                                     PART I

ITEM 1.  DESCRIPTION OF BUSINESS

GENERAL

         Ohio State Financial Services, Inc. ("OSFS") is a unitary savings and
loan holding company organized under Ohio law in March 1997. On September 26,
1997, OSFS acquired all of the common shares issued by Bridgeport Savings and
Loan Association, a savings and loan association organized under Ohio law (the
"Association"), upon the conversion of the Association from mutual to stock form
(the "Conversion").

         As a savings and loan holding company, OSFS is subject to regulation,
supervision and examination by the Office of Thrift Supervision (the "OTS"). The
activities of OSFS have been limited primarily to holding the common stock of
the Association. Consequently, the following discussion focuses primarily on the
business of the Association.

         As an Ohio savings and loan association, the Association is subject to
supervision and regulation by the OTS, the Ohio Department of Commerce, Division
of Financial Institutions (the "Division") and the Federal Deposit Insurance
Corporation (the "FDIC"). The Association is a member of the Federal Home Loan
Bank (the "FHLB") of Cincinnati, and the deposits of the Association are insured
up to applicable limits by the FDIC in the Savings Association Insurance Fund
(the "SAIF").

         The Association conducts business from its main office located in
Bridgeport, Ohio, and one full-service branch located in Shadyside, Ohio. The
principal business of the Association is the origination of permanent mortgage
loans on one- to four-family residential real estate located in the
Association's primary market area, which consists of Belmont County, Ohio, and
Ohio and Marshall Counties, West Virginia. The Association also originates a
limited number of loans for the construction of one- to four-family residences
and permanent mortgage loans secured by nonresidential real estate in its market
area. In addition to real estate lending the Association originates secured and
unsecured consumer loans. For liquidity and interest rate risk management
purposes, the Association invests in interest-bearing deposits in other
financial institutions, U.S. Government and agency obligations and
mortgage-backed securities. Funds for lending and other investment activities
are obtained primarily from savings deposits, which are insured up to applicable
limits by the FDIC, principal repayments of loans and maturities of investment
securities.

         Interest on loans and investments is the Association's primary source
of income. The Association's principal expense is interest paid on deposit
accounts. Operating results are dependent to a significant degree on the net
interest income of the Association, which is the difference between interest
income earned on loans, mortgage-backed securities and other investments and
interest paid on deposits. Like most thrift institutions, the Association's
interest income and interest expense are significantly affected by general
economic conditions and by the policies of various regulatory authorities.


LENDING ACTIVITIES

         GENERAL. The Association's principal lending activity is the
origination of conventional fixed-rate real estate loans secured by one- to
four-family residences located in the Association's primary market area. Though
the Association currently originates loans for its portfolio and not with the
intention of selling such loans in the secondary market, fixed-rate loans are
generally underwritten according to secondary market guidelines. In addition to
real estate lending, the Association originates consumer loans, including loans
secured by deposit accounts, automobile loans, and unsecured loans.

         LOAN MATURITY. The following table sets forth certain information as of
December 31, 1997, regarding the dollar amount of loans maturing in the
Association's portfolio based on their contractual terms to maturity. Demand
loans and other loans having no stated schedule of repayments or no stated
maturity are reported as due in one year or less. Mortgage loans originated by
the Association in its portfolio generally include due-on-sale clauses that
provide the Association with the contractual right to deem the loan immediately
due and payable in the event the borrower transfers the ownership of the
property without the Association's consent. The table does not include the
effects of possible prepayments or scheduled repayments.

         LOANS SECURED BY ONE- TO FOUR-FAMILY REAL ESTATE. The principal lending
activity of the Association is the origination of conventional loans secured by
first mortgages on one- to four-family residences, primarily single-family
residences, located within the Association's primary market area. At December
31, 1997, the Association's one- to four-family residential real estate loans
totaled approximately $19.8 million, or 80.3% of total loans.

         OTS regulations and Ohio law limit the amount which the Association may
lend in relationship to the appraised value of the real estate and improvements
which will secure the loan at the time of loan origination. In accordance with
such regulations, the Association makes loans on one- to four-family residences
of up to 80% of the value of the real estate and improvements thereon (the
"LTV").

         The Association currently offers fixed-rate loans with terms of up to
25 years, though most loans are originated with terms of 15 years. The
Association does offer adjustable-rate mortgage loans ("ARMs") for terms of up
to 25 years, but has originated very few ARMs since 1990. The maximum interest
rate adjustment period on the ARMs is five years, but can be any number of years
less than five. The interest rate adjustments on ARMs presently offered by the
Association are indexed to the quarterly National Average Cost of Funds to
SAIF-Insured Institutions. Rate adjustments are computed by adding a stated
margin, typically 2%, to the index, with a maximum adjustment of 5% over the
term of the loan.

         The Association has purchased interests in loans from other Ohio
financial institutions at times when there was low loan demand in the
Association's primary market area. Such purchases consist of fixed-rate loans
which meet the Association's underwriting standards. The Association's loan
portfolio includes two participation interests in several single-family loans
secured by properties located in Columbus, Ohio. At December 31, 1997, the
outstanding balance of participation loans purchased, which is included in the
one- to four-family loans, was $4.5 million, or 18.4% of the Association's total
loan portfolio.

         LOANS SECURED BY MULTIFAMILY RESIDENCES. The Association originates a
limited number of loans secured by multifamily properties, which contain more
than four units. Multifamily loans are offered with fixed rates of interest for
terms of up to 25 years and have LTVs of up to 75%.

         Multifamily lending is generally considered to involve a higher degree
of risk than one- to four-family residential lending because the borrower
typically depends upon income generated by the project to cover operating
expenses and debt service. The profitability of a project can be affected by
economic conditions, government policies and other factors beyond the control of
the borrower. The Association attempts to reduce the risk associated with
multifamily lending by evaluating the creditworthiness of the borrower and the
projected income from the project and by obtaining personal guarantees on loans
made to corporations and partnerships. The Association requires borrowers to
agree to submit financial statements annually to enable the Association to
monitor the loan and requires an assignment of rents.

         NONRESIDENTIAL REAL ESTATE. The Association also originates a limited
number of loans for the purchase of nonresidential real estate. The
Association's nonresidential real estate loans have fixed rates, terms of up to
25 years and LTVs of up to 80%. Among the properties securing nonresidential
real estate loans are a church and a used car lot, which are located in the
Association's primary market area.


                                      -3-

         Nonresidential real estate lending is generally considered to involve a
higher degree of risk than residential lending due to the relatively larger loan
amounts and the effects of general economic conditions on the successful
operation of income-producing properties. The Association has endeavored to
reduce such risk by evaluating the credit history of the borrower, the location
of the real estate, the financial condition of the borrower, the quality and
characteristics of the income stream generated by the property and the
appraisals supporting the property's valuation.

         At December 31, 1997, approximately $572,000, or 2.3% of the
Association's total loans, were secured by mortgages on nonresidential real
estate.

         LAND LOANS. The Association also originates a limited number of loans
secured by single-family land lots. The Association's land loans are generally
three year amortizing loans and require an LTV of 75% or less. At December 31,
1997, approximately $18,000, or .07% of the Association's total loans, were
secured by land loans made to individuals intending to construct and occupy
single family residences on the properties.

         CONSTRUCTION LOANS. The Association originates a limited number of
loans for the construction of single-family residential real estate.
Construction loans are structured as permanent loans with fixed rates of
interest and terms of up to 25 years. During the first six months, while the
residence is being constructed, the borrower is required to pay interest only.
Construction loans have LTVs of up to 80%, with the value of the land counting
as part of the owner's equity. At December 31, 1997, the Association had
approximately $124,000, or .50% of its total loans, invested in construction
loans, which represented one loan in process from 1995 due to the halt of
construction. During the year ended December 31, 1997, the Association did not
originate any construction loans.

         CONSUMER LOANS. The Association originates various types of consumer
loans, including home improvement loans, loans secured by savings accounts and
motor vehicles and unsecured loans. Consumer loans are made at fixed rates of
interest. Consumer loans secured by a deposit or savings account are made at an
interest rate that is 2% above the rate paid on the underlying deposit account.
Automobile loans are originated with terms of up to six years for new
automobiles and up to three years for used automobiles. All automobile loans are
originated directly by the Association.

         The Association also makes closed-end home equity loans in an amount
which, when added to the prior indebtedness secured by the real estate, does not
exceed 80% of the estimated value of the real estate. Home equity loans are
secured by real estate. The Association does not offer home equity loans with a
line of credit feature.

         Consumer loans may entail greater credit risk than do residential
mortgage loans. The risk of default on consumer loans increases during periods
of recession, high unemployment, and other adverse economic conditions. Although
the Association has not had significant delinquencies on consumer loans, no
assurance can be provided that delinquencies will not increase.

         At December 31, 1997, the Association had approximately $4.1 million,
or 16.5% of its total loans, invested in consumer loans.

         COMMERCIAL LOANS. The Association has occasionally made commercial
loans to businesses in its primary market area. At December 31, 1997, the
Association had approximately $69,000, or .28% of total loans, invested in six
commercial loans. All of the loans were made to local businesses and are secured
by company vehicles. The Association does not currently originate commercial
loans.

         LOAN SOLICITATION AND PROCESSING. Loan originations are generally
obtained from existing customers and members of the local community and from
referrals from real estate brokers, lawyers, accountants, and current and former
customers. The Association also advertises in the local print media and
periodically advertises on radio and television.

         In underwriting real estate loans, the Association typically obtains a
credit report, verification of employment and other documentation concerning the
creditworthiness of the borrower. An appraisal of the fair market value of the
real estate that will be given as security for the loan is prepared by a
certified fee appraiser approved by the Board of Directors. Upon the completion
of the appraisal and the receipt of information on the credit history of the
borrower, the application for a loan is submitted for review in accordance with
the Association's underwriting guidelines which are established annually by the
Board of Directors. The President of the Association has authority to approve
loans of less than $100,000. Loans for


                                      -4-
<PAGE>   6

amounts greater than $100,000 must be approved by the full Board of Directors of
the Association, which meets twice a month.

         Borrowers are required to carry satisfactory fire and casualty
insurance and flood insurance, if applicable, and to name the Association as an
insured mortgagee. The Association obtains an attorney's opinion of title.

         The procedure for approval of construction loans is the same as for
permanent real estate loans, except that an appraiser evaluates the building
plans, construction specifications, and estimates of construction costs. The
Association also evaluates the feasibility of the proposed construction project
and the experience and record of the builder. Once approved, the construction
loan is disbursed in installments based upon periodic inspections of
construction progress.

         Consumer loans are underwritten on the basis of the borrower's credit
history and an analysis of the borrower's income and expenses, ability to repay
the loan, and the value of the collateral, if any. The President of the
Association has authority to approve secured consumer loans of up to $50,000,
and unsecured consumer loans of up to $25,000. The Assistant Vice President and
the Loan Manager of the Association each have the authority to approve
applications for secured consumer loans up to $25,000 and for unsecured loans up
to $10,000 and $2,000, respectively

         LOAN ORIGINATIONS AND PARTICIPATIONS. Currently, the Association is
originating fixed-rate loans for its portfolio and not with the intention of
selling such loans in the secondary market. The Association occasionally
purchases participation interests in fixed-rate loans originated by other
financial institutions which meet the Association's underwriting standards.
Typically the Association purchases a 90% interest in the loan, with the seller
retaining a 10% interest and the servicing of the loan. At December 31, 1997,
the outstanding balance of participation loans purchased, which is included in
the one- to four-family loans, was $4.5 million, or 18.4% of the Association's
total loan portfolio. See "Loans Secured by One- to Four-Family Real Estate."

         The Association issues written commitments to prospective borrowers on
all approved mortgage loans which expire within 30 days of the date of issuance
and charges an application fee. In some instances, commitments may be renewed
or


                                      -5-

extended. At December 31, 1997, the Association had $512,000 of outstanding
commitments to originate loans and $36,000 in undisbursed funds related to
construction loans. Management believes that less than 1% of loan commitments
expire without being funded.

         LOANS TO ONE BORROWER LIMITS. OTS regulations generally limit the
aggregate amount that a savings association may lend to any one borrower to an
amount equal to 15% of the association's unimpaired capital and unimpaired
surplus (the "Lending Limit Capital"). A savings association may lend to one
borrower an additional amount not to exceed 10% of the association's Lending
Limit Capital if the additional amount is fully secured by certain forms of
"readily marketable collateral." Real estate is not considered "readily
marketable collateral." In applying this limit, the regulations require that
loans to certain related or affiliated borrowers be aggregated. An exception to
this limit permits loans of any type to one borrower of up to $500,000.

         Based on such limits, the Association was able to lend approximately
$1.2 million to one borrower at December 31, 1997. The maximum amount that the
Association will lend to one borrower, however, is $500,000. The largest amount
the Association had outstanding to one borrower at December 31, 1997, was
$185,000, which consisted of two loans, each secured by a residential property
and an automobile. At December 31, 1997, the loans were performing in accordance
with their terms.

         LOAN ORIGINATION AND OTHER FEES. The Association realizes loan
origination fees and other fee income from its lending activities. In addition,
the Association realizes income from late payment charges, application fees, and
fees for other miscellaneous services.

         Loan origination fees and other fees are a volatile source of income,
varying with the volume of lending, loan repayments, and general economic
conditions. All nonrefundable loan origination fees and certain direct loan
origination costs are deferred and recognized in accordance with Statement of
Financial Accounting Standards ("SFAS") No. 91 as an adjustment to yield over
the life of the related loan.

         DELINQUENT LOANS, NONPERFORMING ASSETS AND CLASSIFIED ASSETS. The
Association attempts to maintain a high level of asset quality through sound
underwriting policies and efficient collection practices.

         To discourage late payments, the Association charges a late fee of 5%
of the payment amount after 15 days for loans originated since January 1, 1990.
When a loan is 30 days past due, the borrower is sent a delinquency notice. When
a loan is 31 to 60 days delinquent, the Association sends to the borrower
another delinquency notice and a personalized letter and one of the
Association's loan personnel will telephone the borrower. When a loan becomes 60
days delinquent, additional contacts are made and the loan is generally referred
to an attorney for foreclosure, unless a repayment schedule has been
established.

         Loans are reviewed on a monthly basis and are placed on nonaccrual
status when collection in full is considered doubtful by management. Generally,
loans past due more than 90 days as to principal or interest are placed on
nonaccrual status. Interest accrued and unpaid at the time a loan is placed on
nonaccrual status is charged against interest income. Subsequent cash payments
are generally applied to interest income unless, in the opinion of management,
the collection of principal and interest is doubtful. In those cases, subsequent
cash payments would be applied to principal.

         For the year ended December 31, 1997, approximately $8,000 would have
been recorded had such nonaccruing loans been accruing pursuant to contractual
terms. During such period, interest collected on such loans and included in net
income was approximately $2,500.

         Real estate acquired in settlement of loans is classified separately on
the balance sheet at the lower of the recorded investment in the property or its
fair value minus estimated costs of sale. Prior to foreclosure, the loan is
written down to the value of the underlying collateral by a charge to the
allowance for loan losses, if necessary. Any subsequent write-downs are charged
against operating expenses. Operating expenses of such properties, net of
related income or loss on disposition, are included in other expenses. At
December 31, 1997, the Association had no real estate acquired in settlement of
loans.

         The Association classifies its assets on a regular basis in accordance
with federal regulations. Problem assets are classified as "substandard,"
"doubtful" or "loss." "Substandard" assets have one or more defined weaknesses
and are characterized by the distinct possibility that the Association will
sustain some loss if the deficiencies are not corrected. "Doubtful" assets have
the same weaknesses as "substandard" assets, with the additional characteristics
that (i) the weaknesses make collection or liquidation in full, on the basis of
currently existing facts, conditions and values, questionable and (ii) there is
a high possibility of loss. An asset classified "loss" is considered
uncollectible and of such little value that its continuance as an asset of the
Association is not warranted. In addition, federal regulations also contain a
"special mention" category, consisting of assets which do not currently expose
an institution to a different degree of risk to warrant classification but which
possess credit deficiencies or potential weaknesses deserving management's close
attention.

         The aggregate amounts of the Association's classified assets at the
dates indicated were as follows:

         The Association establishes a general allowance for loan losses for any
loan classified as substandard or doubtful. If an asset, or portion thereof, is
classified as loss, the Association establishes a specific allowance for loss in
the amount of 100% of the portion of the asset classified loss or charges off
the portion of any real estate loan deemed to be uncollectible. See "Allowance
for Loan Losses."

         The Association analyzes each classified asset on a monthly basis to
determine whether changes in the classifications are appropriate under the
circumstances. Such analysis focuses on a variety of factors, including the
amount of any delinquency and the reasons for the delinquency, if any, the use
of the real estate securing the loan, the status of the borrower, and the
appraised value of the real estate. As such factors change, the classification
of the asset will change accordingly. At December 31, 1997, the Association had
classified $371,000 of assets as special mention, $71,000 as substandard and no
assets as doubtful or loss.

         ALLOWANCE FOR LOAN LOSSES. Management reviews on a quarterly basis the
allowance for loan losses as it relates to a number of relevant factors,
including, but not limited to, growth and changes in the composition of the loan
portfolio, trends in the level of delinquent and problem loans, current and
anticipated economic conditions in the primary lending area, past loss
experience, and possible losses arising from specific problem assets.

         While management believes that it uses the best information available
to determine the allowance for loan losses, unforeseen market conditions could
result in adjustments and net income could be significantly affected if
circumstances differ substantially from the assumptions used in making the final
determination. In addition, the Association's determination as to the amount of
its allowance for loan losses in subject to review by the OTS, as part of its
examination process, which may result in the establishment of an additional
allowance based upon the judgment of the OTS after a review of the information
available at the time of the OTS examination.

         The following table sets forth the allocation of the allowance for loan
losses by category. The allocations are based on management's assessment of the
risk characteristics of each of the components of the total loan portfolio and
is subject to changes as and when the risk factors of each such component
changes. The allocation is not indicative of either the specific amounts or the
loan categories in which future charge-offs may be taken, nor should it be taken
as an indicator of future loss trends. The allocation of the allowance to each
category is not necessarily indicative of future loss in any particular category
and does not restrict the use of the allowance to absorb losses in any category.

INVESTMENT ACTIVITIES

         GENERAL. Federal regulation and Ohio law permit the Association to
invest in various types of investment securities, including interest-bearing
deposits in other financial institutions, U.S. Treasury and agency obligations,
mortgage-backed securities, and certain other specified investments. The Board
of Directors of the Association has adopted an investment policy which
authorizes management to make investments in U.S. Treasury obligations, U.S.
Government and agency securities, municipal obligations, mortgage-backed
securities, deposits in the FHLB, certificates of deposit in federally-insured
financial institutions, and federal funds at commercial banks. The Association's
investment policy is designed primarily to provide and maintain liquidity within
regulatory guidelines, to maintain a balance of high quality investments to
minimize risk, and to maximize return without sacrificing liquidity and safety.
See "REGULATION."

         The Association's securities available for sale and investment
securities held to maturity at December 31, 1997, did not contain securities of
any issuer with an aggregate book value in excess of 10% of the Association's
equity, excluding those issued by the U. S. Government or its agencies. As of
December 31, 1997, the Association's investment portfolio was comprised of FHLB
stock, U.S. Government and agency securities, mortgage-backed securities, and
stock of a service provider, with an aggregate market value of $ 4.6 million.

         At December 31, 1997, the Association held mortgage-backed securities
in its held to maturity investment portfolio with an amortized cost of $847,000.
The average yield on mortgage-backed securities at December 31, 1997, was 10.29%
The Association's mortgage-backed securities at December 31, 1997, were all
issued by the Government National Mortgage Association (the "GNMA") or the
Federal Home Loan Mortgage Corporation (the "FHLMC"), representing participation
interests in direct pass-through pools of long-term mortgage loans originated
and serviced by the issuers of the securities. Expected maturities will differ
from contractual maturities due to scheduled repayments and because borrowers
may have the right to call or prepay obligations with or without prepayment
penalties.

interest-bearing deposits and investment securities portfolio, including those
designated as available for sale, at the dates indicated:

DEPOSITS AND BORROWINGS

         GENERAL. Deposits have traditionally been the primary source of the
Association's funds for use in lending and other investment activities. In
addition to deposits, the Association derives funds from interest payments and
principal repayments on loans and income on earning assets. Loan payments are a
relatively stable source of funds, while deposit inflows and outflows fluctuate
in response to general interest rates and money market conditions. The
Association may also borrow funds from the FHLB as a source of funds.

         DEPOSITS. Deposits are attracted principally from within the
Association's market area through the offering of a selection of deposit
instruments, including regular passbook savings accounts, NOW accounts, money
market accounts, and certificates of deposit. Interest rates paid, maturity
terms, service fees, and withdrawal penalties for the various types of accounts
are monitored weekly by the President and reviewed monthly by the Board of
Directors of the Association. The Association does not use brokers to attract
deposits. The amount of deposits from outside the Association's market area is
not significant.

         The following table sets forth the dollar amount of deposits in the
various types of accounts offered by the Association at the dates indicated:

         At December 31, 1997, approximately $9.5 million of the Association's
certificates of deposit mature within one year. Based on past experience and the
Association's prevailing pricing strategies, management believes that a
substantial percentage of such certificates will be renewed with the Association
at maturity. If, however, the Association is unable to renew the maturing
certificates for any reason, borrowings of up to $7.0 million are available from
the FHLB of Cincinnati.

         The following table presents the amount of the Association's
certificates of deposit of $100,000 or more by the time remaining until maturity
at December 31, 1997:

         BORROWINGS. The FHLB system functions as a central reserve bank
providing credit for its member institutions and certain other financial
institutions. See "REGULATION - Federal Home Loan Banks." As a member in good
standing of the FHLB of Cincinnati, the Association is authorized to apply for
advances from the FHLB of Cincinnati, provided certain standards of
creditworthiness have been met. Under current regulations, an association must
meet certain qualifications to be eligible for FHLB advances. The extent to
which an association is eligible for such advances will depend upon whether it
meets the Qualified Thrift Lender (the "QTL") test. See "REGULATION - Office of
Thrift Supervision -- Qualified Thrift Lender Test." If an association meets the
QTL test, the association will be eligible for 100% of the advances it would
otherwise be eligible to receive. If an association does not meet the QTL test,
the association will be eligible for such advances only to the extent it holds
specified QTL test assets. At December 31, 1997, the Association was in
compliance with the QTL test. At December 31, 1997, and during the year ended
December 31, 1996, the Association did not utilize FHLB advances. For the year
ended December 31, 1995, the average outstanding balance of FHLB advances was
$23,000. For the year ended December 31, 1997, the Association's average
outstanding balance of FHLB advances was $15,000.

COMPETITION

         The Association faces competition for deposits and loans from branches
of two large independent commercial banks located in Bridgeport and branches of
two larger independent commercial banks and one branch of a super-regional
commercial bank in Shadyside. In addition, competing financial institutions
exist in surrounding communities located in the Association's market area. The
primary factors in competition for deposits are customer service and convenience
of office location. The Association competes for loan originations primarily
through the interest rates and loan fees it charges and through the efficiency
and quality of services it provides to borrowers. Competition is intense and is
affected by, among other things, the general availability of lendable funds,
general and local economic conditions, current interest rate levels and other
factors which are not readily predictable. The Association does not offer all of
the products and services offered by some of its competitors, particularly
commercial banks.

SUBSIDIARY ACTIVITY

         On September 25, 1997, the Association dissolved its wholly-owned
subsidiary, Trailway Financial, Inc. ("Trailway"). Trailway was formed to
acquire stock in Intrieve, Inc., the Association's data processing servicing
company.

EMPLOYEES

         At December 31, 1997, the Association had 14 full-time employees and no
part-time employees. The Association believes that relations with its employees
are excellent. The Association offers health, life and disability benefits to
all employees and has a defined benefit pension plan and a 401(k) plan for its
eligible full-time employees. None of the employees of the Association is
represented by a collective bargaining unit.

YEAR 2000

         The Association's operations, like those of most financial
institutions, depend almost entirely on computer systems. The Association is
addressing the potential problems associated with the possibility that the
computers which control or operate the Association's operating systems,
facilities and infrastructure may not be programmed to read four-digit date
codes and, upon arrival of the year 2000, may recognize the two-digit code "00"
as the year 1900, causing systems to fail to


                                      -13-
<PAGE>   15

function or to generate erroneous data. The Association is working with the
companies that supply or service its computer-operated or computer-dependent
systems to identify and remedy any year-2000 related problems.

         At this time, no specific material expenses have been identified which
are reasonably likely to be incurred by the Association in connection with
year-2000 issues and the Association does not expect to incur significant
expense to implement corrective measures. No assurance can be given at this
time, however, that significant expense will not be incurred in future periods.
In the event that the Association is ultimately required to purchase replacement
computer systems, programs and equipment, or that substantial expense must be
incurred to make the Association's current systems, programs and equipment
year-2000 compliant, OSFS's net income and financial condition could be
adversely affected. While the Association is endeavoring to ensure that its
computer-dependent operations are year-2000 compliant, no assurance can be given
that some year-2000 problems will not occur.

         In addition to possible expense related to its own systems, OSFS could
incur losses if year-2000 issues adversely affect the Association's depositors
or borrowers. Such problems could include delayed loan payments due to year-2000
problems affecting any of the Association's significant borrowers or impairing
the payroll systems of large employers in the Association's primary market area.
Because the Association's loan portfolio is highly diversified with regard to
individual borrowers and types of businesses and the Association's primary
market area is not significantly dependent upon one employer or industry, the
Association does not expect any significant or prolonged year-2000 related
difficulties that will affect net earnings or cash flow.

                                   REGULATION

GENERAL

         OSFS is a savings and loan holding company within the meaning of the
Home Owners Loan Act, as amended (the "HOLA"). Consequently, OSFS is subject to
regulation, examination and oversight by the OTS and must submit periodic
reports to the OTS concerning its activities and financial condition. In
addition, as a corporation organized under Ohio law, OSFS is subject to
provisions of the Ohio Revised Code applicable to corporations generally.

         As a savings and loan association chartered under the laws of Ohio, the
Association is subject to regulation, examination and oversight by the
Superintendent of the Division (the "Ohio Superintendent"). Because the
Association's deposits are insured by the FDIC, the Association also is subject
to regulatory oversight by the FDIC. the Association must file periodic reports
with the OTS concerning its activities and financial condition. Examinations are
conducted periodically by federal and state regulators to determine whether the
Association is in compliance with various regulatory requirements and is
operating in a safe and sound manner. The Association is a member of the FHLB
and is subject to certain regulations promulgated by the Board of Governors of
the Federal Reserve System (the "FRB").

         Congress is considering legislation to eliminate the federal savings
and loan charter and the separate federal regulation of savings and loan
associations. Pursuant to such legislation, Congress may eliminate the OTS and
the Association may be regulated under federal law as a bank or be required to
change its charter. Such change in regulation or charter would likely change the
range of activities in which the Association may engage and would probably
subject the Association to more regulation by the FDIC. In addition, OSFS might
become subject to a different set of holding company regulations limiting the
activities in which OSFS may engage and subjecting OSFS to additional regulatory
requirements, including separate capital requirements. At this time, OSFS cannot
predict when or whether Congress may actually pass legislation regarding OSFS's
and the Association's regulatory requirements or charter. Although such
legislation, if enacted, may change the activities in which OSFS or the
Association are authorized to engage, it is not anticipated that the current
activities of either OSFS or the Association will be materially affected by
those activity limits.

OHIO CORPORATION LAW

         MERGER MORATORIUM STATUTE. Chapter 1704 of the Ohio Revised Code
regulates certain takeover bids affecting certain public corporations which have
significant ties to Ohio. This statute prohibits, with some exceptions, any
merger, combination or consolidation and any of certain other sales, leases,
distributions, dividends, exchanges, mortgages or transfers between an Ohio
corporation and any person who has the right to exercise, alone or with others,
10% or more of the voting power of such corporation (an "Interested
Shareholder"), for three years following the date on which such person first
becomes an Interested Shareholder. Such a business combination is permitted only
if, prior to the time such person first


                                      -14-
<PAGE>   16

becomes an Interested Shareholder, the Board of Directors of the issuing
corporation has approved the purchase of shares which resulted in such person
first becoming an Interested Shareholder.

         After the initial three-year moratorium, such a business combination
may not occur unless (1) one of the specified exceptions applies, (2) the
holders of at least two-thirds of the voting shares, and of at least a majority
of the voting shares not beneficially owned by the Interested Shareholder,
approve the business combination at a meeting called for such purpose, or (3)
the business combination meets certain statutory criteria designed to ensure
that the issuing public corporation's remaining shareholders receive fair
consideration for their shares.

         An Ohio corporation may, under certain circumstances, "opt out" of the
statute by specifically providing in its articles of incorporation that the
statute does not apply to any business combination of such corporation. However,
the statute still prohibits for twelve months any business combination that
would have been prohibited but for the adoption of such an opt-out amendment.
The statute also provides that it will continue to apply to any business
combination between a person who became an Interested Shareholder prior to the
adoption of such an amendment as if the amendment had not been adopted. Neither
OSFS nor the Association has opted out of the protection afforded by Chapter
1704.

         CONTROL SHARE ACQUISITION. Section 1701.831 of the Ohio Revised Code
(the "Control Share Acquisition Statute") requires that, with certain
exceptions, acquisitions of voting securities which would result in the
acquiring shareholder owning 20%, 33-1/3% or 50% of the outstanding voting
securities of an Ohio corporation (a "Control Share Acquisition") must be
approved in advance by the holders of at least a majority of the outstanding
voting shares of such corporation represented at a meeting at which a quorum is
present and a majority of the portion of the outstanding voting shares
represented at such a meeting excluding the voting shares owned by the acquiring
shareholder, by certain other persons who acquire or transfer voting shares
after public announcement of the acquisition or by certain officers of the
corporation or directors of the corporation who are employees of the
corporation. The Control Share Acquisition Statute was intended, in part, to
protect shareholders of Ohio corporations from coercive tender offers.

         TAKEOVER BID STATUTE. Ohio law provides that an offeror may not make
not make a tender offer or request or invitation for tenders that would result
in the offeror beneficially owning more than ten percent of any class of the
target company's equity securities unless such offeror files certain information
with the Ohio Division of Securities (the "Securities Division") and provides
such information to the target company and the offerees within Ohio. The
Securities Division may suspend the continuation of the control bid if the
Securities Division determines that the offeror's filed information does not
provide full disclosure to the offerees of all material information concerning
the control bid. The statue also provides that an offeror may not acquire any
equity security of a target company within two years of the offeror's previous
acquisition of any equity security of the same target company pursuant to a
control bid unless the Ohio offerees may sell such security to the offeror on
substantially the same terms as provided by the previous control bid. The
statute does not apply to a transaction if either the offeror or the target
company is a savings and loan holding company and the proposed transaction
requires federal regulatory approval.

OHIO SAVINGS AND LOAN REGULATION

         The Ohio Superintendent is responsible for the regulation and
supervision of Ohio savings and loan associations in accordance with the laws of
the State of Ohio and imposes assessments on Ohio associations based on their
asset size to cover the costs of supervision and examination. Ohio law
prescribes the permissible investments and activities of Ohio savings and loan
associations, including the types of lending that such associations may engage
in and the investments in real estate, subsidiaries and corporate or government
securities that such associations may make. The ability of Ohio associations to
engage in these state-authorized investments and activities is subject to
oversight and approval by the FDIC, if such investments or activities are not
permissible for a federally-chartered savings association. The Ohio
Superintendent also has approval authority over any mergers involving, or
acquisitions of control of, Ohio savings and loan associations. The Ohio
Superintendent may initiate certain supervisory measures or formal enforcement
actions against Ohio associations. Ultimately, if the grounds provided by law
exist, the Superintendent may place an Ohio association in conservatorship or
receivership.

         In addition to being governed by the laws of Ohio specifically
governing savings and loan associations, the Association is also governed by
Ohio corporate law, to the extent such law does not conflict with the laws
specifically governing savings and loan associations.

OFFICE OF THRIFT SUPERVISION

         GENERAL. The OTS is an office of the Department of the Treasury and is
responsible for the regulation and supervision of all federally-chartered
savings associations and all other savings associations the deposits of which
are insured by the FDIC in the SAIF. The OTS issues regulations governing the
operation of savings associations, regularly examines such associations and
imposes assessments on savings associations based on their asset size to cover
the costs of general supervision and examination. The OTS also may initiate
enforcement actions against savings associations and certain persons affiliated
with them for violations of laws or regulations or for engaging in unsafe or
unsound practices. If the grounds provided by law exist, the OTS may appoint a
conservator or receiver for a savings association.

         Savings associations are subject to regulatory oversight under various
consumer protection and fair lending laws. These laws govern, among other
things, truth-in-lending disclosures, equal credit opportunity, fair credit
reporting and community reinvestment. Failure to abide by federal laws and
regulations governing community reinvestment could limit the ability of an
association to open a new branch or engage in a merger. Community reinvestment
regulations evaluate how well and to what extent an institution lends and
invests in its designated service area, with particular emphasis on low- to
moderate-income communities and borrowers in that area.

         REGULATORY CAPITAL REQUIREMENTS. The Association is required by OTS
regulations to meet certain minimum capital requirements. The tangible capital
requirement requires savings associations to maintain "tangible capital" of not
less than 1.5% of their adjusted total assets. Tangible capital is defined in
OTS regulations as core capital minus any intangible assets.

         "Core capital" is comprised of common stockholders' equity (including
retained earnings), noncumulative preferred stock and related surplus, minority
interests in consolidated subsidiaries, certain nonwithdrawable accounts and
pledged deposits of mutual associations. OTS regulations require savings
associations to maintain core capital of at least 3% of their total assets. The
OTS has proposed to amend the core capital requirement so that those
associations that do not have the highest examination rating and exceed an
acceptable level of risk will be required to maintain core capital of from 4% to
5%, depending on the association's examination rating and overall risk. The
Association does not anticipate that it will be adversely affected if the core
capital requirement regulation is amended as proposed.

         OTS regulations require that savings associations maintain "risk-based
capital" in an amount not less than 8% of their risk-weighted assets. Risk-based
capital is defined as core capital plus certain additional items of capital,
which in the case of the Association includes allowances for loan and lease
losses at December 31, 1997.

         The OTS has adopted an interest rate risk component to the risk-based
capital requirement, though the implementation of that component has been
delayed. Pursuant to the interest rate risk component, a savings association
will have to measure the effect of an immediate 200 basis point change in
interest rates on the value of its portfolio as determined under the methodology
of the OTS. If the measured interest rate risk is above the level deemed normal
under the regulation, the association will be required to deduct one-half of
such excess exposure from its total capital when determining its risk-based
capital. In general, an association with less than $300 million in assets and a
risk-based capital ratio in excess of 12% will not be subject to the interest
rate risk component. Pending implementation of the interest rate risk component,
the OTS has the authority to impose a higher individualized capital requirement
on any savings association it deems to have excess interest rate risk. The OTS
also may adjust the risk-based capital requirement on an individualized basis to
take into account risks due to concentrations of credit and non-traditional
activities.

         The OTS has adopted regulations governing prompt corrective action to
resolve the problems of capital deficient and otherwise troubled savings
associations. At each successively lower defined capital category, an
association is subject to more restrictive and more numerous mandatory or
discretionary regulatory actions or limits, and the OTS has less flexibility in
determining how to resolve the problems of the institution. In addition, the OTS
generally can downgrade an association's capital category, notwithstanding its
capital level, if, after notice and opportunity for hearing, the association is
deemed to be engaging in an unsafe or unsound practice because it has not
corrected deficiencies that resulted in it receiving a less than satisfactory
examination rating on matters other than capital or it is deemed to be in an
unsafe or unsound condition. All undercapitalized associations must submit a
capital restoration plan to the OTS within 45 days after becoming
undercapitalized. Such associations will be subject to increased monitoring and
asset growth restrictions and will be required to obtain prior approval for
acquisitions, branching and engaging in new lines of business. Furthermore,
critically undercapitalized institutions must be placed in conservatorship or
receivership within 90 days of reaching that capitalization


                                      -16-
<PAGE>   18

level, except under limited circumstances. The Association's capital at December
31, 1997, met the standards for the highest category, a "well-capitalized"
institution.

         Federal law prohibits a savings association from making a capital
distribution to anyone or paying management fees to any person having control of
the association if, after such distribution or payment, the association would be
undercapitalized. In addition, each company controlling an undercapitalized
association must guarantee that the association will comply with its capital
plan until the association has been adequately capitalized on an average during
each of four preceding calendar quarters and must provide adequate assurances of
performance. The aggregate liability pursuant to such guarantee is limited to
the lesser of (a) an amount equal to 5% of the association's total assets at the
time the institution became undercapitalized and (b) the amount that is
necessary to bring the association into compliance with all capital standards
applicable to such association at the time the association fails to comply with
its capital restoration plan.

         LIQUIDITY. OTS regulations require that a savings association maintain
an average daily balance of liquid assets (cash, certain time deposits, bankers'
acceptances and specified United States government, state or federal agency
obligations) equal to a monthly average of not less than 4% of its net
withdrawable savings deposits plus borrowings payable in one year or less.
Monetary penalties may be imposed upon associations failing to meet these
liquidity requirements. The eligible liquidity of the Association at December
31, 1997, was approximately $10.2 million, or 37%, and exceeded the applicable
4.0% liquidity requirement by approximately $9.1 million.

         QUALIFIED THRIFT LENDER TEST. Savings associations are required to meet
the QTL test. Prior to September 30, 1996, the QTL test required savings
associations to maintain a specified level of investments in assets that are
designated as qualifying thrift investments ("QTI"), which are generally related
to domestic residential real estate and manufactured housing and include credit
card, student and small business loans and stock issued by any FHLB, the FHLMC
or the FNMA. Under such test, 65% of an institution's "portfolio assets" (total
assets less goodwill and other intangibles, property used to conduct business
and 20% of liquid assets) must consist of QTI on a monthly average basis in nine
out of every 12 months. Effective September 30, 1996, a savings association may
also qualify as a QTL by meeting the definition of "domestic building and loan
association" under the Internal Revenue Code of 1986, as amended (the "Code").
In order for an institution to meet the definition of a "domestic building and
loan association" under the Code, at least 60% of such institution's assets must
consist of specified types of property, including cash loans secured by
residential real estate or deposits, educational loans and certain governmental
obligations. The OTS may grant exceptions to the QTL test under certain
circumstances. If a savings association fails to meet the QTL test, the
association and its holding company become subject to certain operating and
regulatory restrictions. A savings association that fails to meet the QTL test
will not be eligible for new FHLB advances. At December 31, 1997, the
Association met the QTL test.

         LENDING LIMIT. OTS regulations generally limit the aggregate amount
that a savings association can lend to one borrower to an amount equal to 15% of
the association's Lending Limit Capital. A savings association may lend to one
borrower an additional amount not to exceed 10% of the association's Lending
Limit Capital, if the additional amount is fully secured by certain forms of
"readily marketable collateral." Real estate is not considered "readily
marketable collateral." Certain types of loans are not subject to the lending
limit. A general exception to the 15% limit provides that an association may
lend to one borrower up to $500,000, for any purpose. In applying the limit on
loans to one borrower, the regulations require that loans to certain related
borrowers be aggregated. At December 31, 1997, the Association was in compliance
with this lending limit.

         TRANSACTIONS WITH INSIDERS AND AFFILIATES. Loans to executive officers,
directors and principal shareholders and their related interests must conform to
the lending limit on loans to one borrower, and the total of such loans to
executive officers, directors, principal shareholders and their related
interests cannot exceed the association's Lending Limit Capital (or 200% of
Lending Limit Capital for qualifying institutions with less than $100 million in
deposits). Most loans to directors, executive officers and principal
shareholders must be approved in advance by a majority of the "disinterested"
members of the board of directors of the association, with any "interested"
director not participating. All loans to directors, executive officers and
principal shareholders must be made on terms substantially the same as offered
in comparable transactions with the general public or as offered to all
employees in a company-wide benefit program. Loans to executive officers are
subject to additional limitations. The Association was in compliance with such
restrictions at December 31, 1997.

         All transactions between savings associations and their affiliates must
comply with Sections 23A and 23B of the Federal Reserve Act (the "FRA"). An
affiliate of a savings association is any company or entity that controls, is
controlled by or is under common control with the savings association. OSFS is
an affiliate of the Association . Generally, Sections 23A and 23B of the FRA (i)
limit the extent to which a savings association or its subsidiaries may engage
in "covered


                                      -17-
<PAGE>   19

transactions" with any one affiliate to an amount equal to 10% of such
institution's capital stock and surplus, (ii) limit the aggregate of all such
transactions with all affiliates to an amount equal to 20% of such capital stock
and surplus, and (iii) require that all such transactions be on terms
substantially the same, or at least as favorable to the association, as those
provided in transactions with a non-affiliate. The term "covered transaction"
includes the making of loans, purchasing of assets, issuance of a guarantee and
other similar types of transactions. In addition to the limits in Sections 23A
and 23B, a savings association may not make any loan or other extension of
credit to an affiliate unless the affiliate is engaged only in activities
permissible for a bank holding company and may not purchase or invest in
securities of any affiliate except shares of a subsidiary. The Association was
in compliance with these requirements and restrictions at December 31, 1997.

         LIMITATIONS ON CAPITAL DISTRIBUTIONS. The OTS imposes various
restrictions or requirements on the ability of associations to make capital
distributions, including dividend payments. An association which has converted
from mutual to stock form is prohibited from declaring or paying any dividends
or from repurchasing any of its stock if, as a result, the net worth of the
association would be reduced below the amount required to be maintained for the
liquidation account established in connection with its mutual to stock
conversion. OTS regulations also establish a three-tier system limiting capital
distributions according to ratings of associations based on their capital level
and supervisory condition.

         Tier 1 consists of associations that, before and after the proposed
distribution, meet their fully phased-in capital requirements. Associations in
this category may make capital distributions during any calendar year up to the
greater of (i) 100% of net income, current year-to-date, plus 50% of the amount
by which the lesser of the association's tangible, core or risk-based capital
exceeds its fully phased-in capital requirement for such capital component, as
measured at the beginning of the calendar year, and (ii) the amount authorized
for a Tier 2 association. A Tier 1 association deemed to be in need of more than
normal supervision by the OTS may be downgraded to a Tier 2 or Tier 3
association. The Association meets the requirements for a Tier 1 association and
has not been notified of any need for more than normal supervision.

         Tier 2 consists of associations that, before and after the proposed
distribution, meet their current minimum, but not fully phased-in, capital
requirements. Associations in this category may make capital distributions of up
to 75% of net income over the most recent four quarters. Tier 3 associations do
not meet current minimum capital requirements and must obtain OTS approval of
any capital distribution. Tier 2 associations that propose to make a capital
distribution in excess of the noted safe harbor level must also obtain OTS
approval. Tier 2 associations proposing to make a capital distribution within
the safe harbor provisions and Tier 1 associations proposing to make any capital
distribution need only submit written notice to the OTS 30 days prior to such
distribution.

         As a subsidiary of OSFS, the Association is required to give the OTS 30
days' notice prior to declaring any dividend on its stock. The OTS may object to
the distribution during such 30-day period based on safety and soundness
concerns.

         HOLDING COMPANY REGULATION. OSFS is a savings and loan holding company
within the meaning of the HOLA. As such, OSFS has registered with the OTS and is
subject to OTS regulations, examination, supervision and reporting requirements.

         The HOLA generally prohibits a savings and loan holding company from
controlling any other savings association or savings and loan holding company,
without prior approval of the OTS, or from acquiring or retaining more than 5%
of the voting shares of a savings association or holding company thereof, which
is not a subsidiary. Under certain circumstances, a savings and loan holding
company is permitted to acquire, with the approval of the OTS, up to 15% of the
previously unissued voting shares of an undercapitalized savings association for
cash without such savings association being deemed to be controlled by OSFS.
Except with the prior approval of the OTS, no director or officer of a savings
and loan holding company or person owning or controlling by proxy or otherwise
more than 25% of such holding company's stock may also acquire control of any
savings institution, other than a subsidiary institution, or any other savings
and loan holding company.

         As a unitary savings and loan holding company, OSFS generally has no
restrictions on its activities. Such companies are the only financial
institution holding companies which may engage in any commercial, securities and
insurance activities without restriction. Congress is considering legislation
which may limit OSFS's ability to engage in these activities. It cannot be
predicted whether and in what form these proposals might become law. However,
such limits would not impact OSFS's current activities, which consist solely of
holding stock of the Association . The broad latitude to engage in activities
under current law can be restricted. If the OTS determines that there is
reasonable cause to believe that the continuation by a savings and loan holding
company of an activity constitutes a serious risk to the financial safety,
soundness or stability of its subsidiary savings association, the OTS may impose
such restrictions as deemed necessary to address such risk, including limiting
(i) payment of dividends by the savings association, (ii) transactions between
the savings association


                                      -18-
<PAGE>   20

and its affiliates, and (iii) any activities of the savings association that
might create a serious risk that the liabilities of OSFS and its affiliates may
be imposed on the savings association. Notwithstanding the foregoing rules as to
permissible business activities of a unitary savings and loan holding company,
if the savings association subsidiary of a holding company fails to meet the QTL
test, then such unitary holding company would become subject to the activities
restrictions applicable to multiple holding companies. At December 31, 1997, the
Association met both those tests.

         If OSFS acquired control of another savings institution, other than
through a merger or other business combination with the Association, OSFS would
become a multiple savings and loan holding company. Unless the acquisition was
an emergency thrift acquisition and each subsidiary savings association met the
QTL test, the activities of OSFS and any of its subsidiaries (other than the
Association other subsidiary savings associations) would thereafter be subject
to activity restrictions. The HOLA provides that, among other things, no
multiple savings and loan holding company or subsidiary thereof that is not a
savings institution shall commence or continue for a limited period of time
after becoming a multiple savings and loan holding company or subsidiary
thereof, any business activity other than (i) furnishing or performing
management services for a subsidiary savings institution, (ii) conducting an
insurance agency or escrow business, (iii) holding, managing or liquidating
assets owned by or acquired from a subsidiary savings institution, (iv) holding
or managing properties used or occupied by a subsidiary savings institution, (v)
acting as trustee under deeds of trust, (vi) those activities previously
directly authorized by federal regulation as of March 5, 1987, to be engaged in
by multiple holding companies, or (vii) those activities authorized by the FRB
as permissible for bank holding companies, unless the OTS by regulation
prohibits or limits such activities for savings and loan holding companies.
Those activities described in (vii) above must also be approved by the OTS prior
to being engaged in by a multiple holding company.

         The OTS may approve acquisitions resulting in the formation of a
multiple savings and loan holding company that controls savings associations in
more than one state only if the multiple savings and loan holding company
involved controls a savings association that operated a home or branch office in
the state of the association to be acquired as of March 5, 1987, or if the laws
of the state in which the institution to be acquired is located specifically
permit institutions to be acquired by state-chartered institutions or savings
and loan holding companies located in the state where the acquiring entity is
located (or by a holding company that controls such state-chartered savings
institutions). As under prior law, the OTS may approve an acquisition resulting
in a multiple savings and loan holding company controlling savings associations
in more than one state in the case of certain emergency thrift acquisitions.
Bank holding companies have had more expansive authority to make interstate
acquisitions than savings and loan holding companies since August 1995.

         FEDERAL REGULATION OF ACQUISITIONS OF CONTROL OF OSFS AND THE
ASSOCIATION. In addition to the Ohio law limitations on the merger and
acquisition of the Association and OSFS, federal limitations generally require
regulatory approval of acquisitions at specified levels. Under pertinent federal
law and regulations, no person, directly or indirectly, or acting in concert
with others, may acquire control of the Association or OSFS without 60 days'
prior notice to the OTS. "Control" is generally defined as having more than 25%
ownership or voting power; however, ownership or voting power of more than 10%
may be deemed "control" if certain factors are in place. If the acquisition of
control is by a company, the acquiror must obtain approval, rather than give
notice, of the acquisition as a savings and loan holding company.

         In addition, any merger of the Association must be approved by the OTS
as well as the Superintendent. Further, any merger of OSFS in which OSFS is not
the resulting company must also be approved by both the OTS and the
Superintendent.

FEDERAL DEPOSIT INSURANCE CORPORATION

         DEPOSIT INSURANCE AND ASSESSMENTS. The FDIC is an independent federal
agency that insures the deposits, up to prescribed statutory limits, of
federally insured banks and savings and loan associations and safeguards the
safety and soundness of the banking and savings and loan industries. The FDIC
administers two separate insurance funds, the Bank Insurance Fund ("BIF") for
commercial banks and state savings banks and the SAIF for savings associations.
The Association is a member of the SAIF and its deposit accounts are insured by
the FDIC up to the prescribed limits. The FDIC has examination authority over
all insured depository institutions, including the Association , and has
authority to initiate enforcement actions against federally-insured savings
associations if the FDIC does not believe the OTS has taken appropriate action
to safeguard safety and soundness and the deposit insurance fund.

         The FDIC is required to maintain designated levels of reserves in the
SAIF and in the BIF. The FDIC may increase assessment rates for either fund if
necessary to restore the fund's ratio of reserves to insured deposits to its
target level within a reasonable time and may decrease such rates if such target
level has been met. The FDIC has established a risk-based


                                      -19-
<PAGE>   21

assessment system for both SAIF and BIF members. Under this system, assessments
vary based on the risk the institution poses to its deposit insurance fund. The
risk level is determined based on the institution's capital level and the FDIC's
level of supervisory concern about the institution.

         Prior to September 1996, the SAIF's ratio of reserves to insured
deposits was significantly below the level required by law, while the BIF's
ratio was above the required level. As a result, institutions with SAIF-insured
deposits were paying higher deposit insurance assessments than institutions with
BIF-insured deposits. Federal legislation providing for the recapitalization of
the SAIF became effective in September 1996 and included a special assessment of
$.657 per $100 of SAIF-insured deposits held at March 31, 1995. The Association
had approximately $29.1 million in deposits at March 31, 1995, and paid a
special assessment of $190,000.

         STATE-CHARTERED ASSOCIATION ACTIVITIES. The ability of state-chartered
associations to engage in any state-authorized activities or make any
state-authorized investments is limited if such activity is conducted or
investment is made in a manner different than that permitted for, or subject to
different terms and conditions than those imposed on, federally chartered
savings associations. Engaging as a principal in any such activity or investment
not permissible for a federal association is subject to approval by the FDIC.
Such approval will not be granted unless certain capital requirements are met
and there is not a significant risk to the FDIC insurance fund. All of the
Association's activities and investments at December 31, 1997, were permissible
for a federal association.

FRB RESERVE REQUIREMENTS

         FRB regulations currently require savings associations to maintain
reserves of 3% of net transaction accounts (primarily NOW accounts) up to $47.8
million (subject to an exemption of up to $4.7 million), and of 10% of net
transaction accounts in excess of $47.8 million. At December 31, 1997, the
Association was in compliance with the new reserve requirements.

FEDERAL HOME LOAN BANKS

         The FHLBs provide credit to their members in the form of advances. The
Association is a member of the FHLB of Cincinnati and must maintain an
investment in the capital stock of the FHLB of Cincinnati in an amount equal to
the greater of 1.0% of the aggregate outstanding principal amount of the
Association's residential mortgage loans, home purchase contracts and similar
obligations at the beginning of each year, or 5% of its advances from the FHLB
of Cincinnati. The Association was in compliance with this requirement with an
investment in stock of the FHLB of Cincinnati of $348,000 at December 31, 1997.

         FHLB advances to member institutions who meet the QTL test are
generally limited to the lower of (i) 25% of the member's assets or (ii) 20
times the member's investment in FHLB stock. At December 31, 1997, the
Association's maximum limit on advances was approximately $7.0 million. The
granting of advances is also subject to the FHLB's collateral and credit
underwriting guidelines.

         Upon the origination or renewal of a loan or advance, the FHLB is
required by law to obtain and maintain a security interest in collateral in one
or more of the following categories: fully-disbursed, whole first mortgage loans
on improved residential property or securities representing a whole interest in
such loans; securities issued, insured or guaranteed by the United States
Government or an agency thereof; deposits in any FHLB; or other real estate
related collateral (up to 30% of the member association's capital) acceptable to
the FHLB, if such collateral has a readily ascertainable value and the FHLB can
perfect its security interest in the collateral.

         The FHLB is required to establish standards of community investment or
service that its members must maintain for continued access to long-term
advances. The standards take into account a member's performance under the
Community Reinvestment Act and its record of lending to first-time home buyers.
All long-term advances by the FHLB must be made only to provide funds for
residential housing finance.

                                    TAXATION

FEDERAL TAXATION

         OSFS and the Association are each subject to the federal tax laws and
regulations which apply to corporations generally. In addition to the regular
income tax, OSFS and the Association may be subject to the alternative minimum
tax which is imposed at a minimum tax rate of 20% on "alternative minimum
taxable income" (which is the sum of a corporation's regular taxable income,
with certain adjustments, and tax preference items), less any available
exemption. Such tax preference items include interest on certain tax-exempt
bonds issued after August 7, 1986. In addition, 75% of the amount by which a
corporation's "adjusted current earnings" exceeds its alternative minimum
taxable income computed without regard to this preference item and prior to
reduction by net operating losses, is included in alternative minimum taxable
income. Net operating losses can offset no more than 90% of alternative minimum
taxable income. The alternative minimum tax is imposed to the extent it exceeds
the corporation's regular income tax. Payments of alternative minimum tax may be
used as credits against regular tax liabilities in future years. However, the
Taxpayer Relief Act of 1997 repealed the alternative minimum tax for certain
"small corporations" for tax years beginning after December 31, 1997. A
corporation initially qualifies as a small corporation if it had average gross
receipts of $5,000,000 or less for the three tax years ending with its first tax
year beginning after December 31, 1996. Once a corporation is recognized as a
small corporation, it will continue to be exempt from the alternative minimum
tax for as long as its average gross receipts for the prior three-year period
does not exceed $7,500,000. In determining if a corporation meets this
requirement, the first year that it achieved small corporation status is not
taken into consideration.

         The Association's average gross receipts for the three tax years ending
on December 31, 1997, is $2.5 million and as a result, the Association does
qualify as a small corporation exempt from the alternative minimum tax.

         Prior to the enactment of the Small Business Jobs Protection Act (the
"Act"), which was signed into law on August 21, 1996, certain thrift
institutions, such as the Association , were allowed deductions for bad debts
under methods more favorable than those granted to other taxpayers. Qualified
thrift institutions could compute deductions for bad debts using either the
specific charge-off method of Section 166 of the Code or one of two reserve
methods of Section 593 of the Code. The reserve methods under Section 593 of the
Code permitted a thrift institution annually to elect to deduct bad debts under
either (i) the "percentage of taxable income" method applicable only to thrift
institutions, or (ii) the "experience" method that also was available to small
banks. Under the "percentage of taxable income" method, a thrift institution
generally was allowed a deduction for an addition to its bad debt reserve equal
to 8% of its taxable income (determined without regard to this deduction and
with additional adjustments). Under the "experience" method, a thrift
institution was generally allowed a deduction for an addition to its bad debt
reserve equal to the greater of (i) an amount based on its actual average
experience for losses in the current and five preceding taxable years, or (ii)
an amount necessary to restore the reserve to its balance as of the close of the
base year. A thrift institution could elect annually to compute its allowable
addition to bad debt reserves for qualifying loans either under the experience
method or the percentage of taxable income method. For tax years 1995, 1994, and
1993, the Association used the percentage of taxable income method.

         The Act eliminated the percentage of taxable income method of
accounting for bad debts by thrift institutions, effective for taxable years
beginning after 1995. Thrift institutions that are treated as small banks are
allowed to utilize the experience method applicable to such institutions, while
thrift institutions that are treated as large banks are required to use only the
specific charge off method.

         A thrift institution required to change its method of computing
reserves for bad debt will treat such change as a change in the method of
accounting, initiated by the taxpayer and having been made with the consent of
the Secretary of the Treasury. Section 481(a) of the Code requires certain
amounts to be recaptured with respect to such change. Generally, the amounts to
be recaptured will be determined solely with respect to the "applicable excess
reserves" of the taxpayer. The amount of the applicable excess reserves will be
taken into account ratably over a six-taxable year period, beginning with the
first taxable year beginning after 1995, subject to the residential loan
requirement described below. In the case of a thrift institution that is treated
as a large bank, the amount of the institution's applicable excess reserves
generally is the excess of (i) the balances of its reserve for losses on
qualifying real property loans (generally loans secured by improved real estate)
and its reserve for losses on nonqualifying loans (all other types of loans) as
of the close of its last taxable year beginning before January 1, 1996, over
(ii) the balances of such reserves as of the close of its last  taxable year
beginning before January 1, 1988 (I.E., the "pre-1988 reserves"). In the case
of a thrift institution that is treated as a small bank, like the
Association, the amount of the institution's applicable excess reserves
generally is the excess of (i) the balances of its reserve for losses on
qualifying real property loans and its reserve for losses on nonqualifying
loans as of the close of its last

                                      -21-
<PAGE>   23

taxable year beginning before January 1, 1996, over (ii) the greater of the
balance of (a) its pre-1988 reserves or (b) what the thrift's reserves would
have been at the close of its last year beginning before January 1, 1996, had
the thrift always used the experience method.

         For taxable years that begin after December 31, 1995, and before
January 1, 1998, if a thrift meets the residential loan requirement for a tax
year, the recapture of the applicable excess reserves otherwise required to be
taken into account as a Code Section 481(a) adjustment for the year will be
suspended. A thrift meets the residential loan requirement if, for the tax year,
the principal amount of residential loans made by the thrift during the year is
not less than its base amount. The "base amount" generally is the average of the
principal amounts of the residential loans made by the thrift during the six
most recent tax years beginning before January 1, 1996. A residential loan is a
loan as described in Section 7701(a)(19)(C)(v) (generally a loan secured by
residential or church property and certain mobile homes), but only to the extent
that the loan is made to the owner of the property.

         The balance of the pre-1988 reserves is subject to the provisions of
Section 593(e), as modified by the Act, which require recapture in the case of
certain excessive distributions to shareholders. The pre-1988 reserves may not
be utilized for payment of cash dividends or other distributions to a
shareholder (including distributions in dissolution or liquidation) or for any
other purpose (except to absorb bad debt losses). Distribution of a cash
dividend by a thrift institution to a shareholder is treated as made: first, out
of the institution's post-1951 accumulated earnings and profits; second, out of
the pre-1988 reserves; and third, out of such other accounts as may be proper.
To the extent a distribution by the Association to OSFS is deemed paid out of
its pre-1988 reserves under these rules, the pre-1988 reserves would be reduced
and the gross income of the Association for tax purposes would be increased by
the amount which, when reduced by the income tax, if any, attributable to the
inclusion of such amount in its gross income, equals the amount deemed paid out
of the pre-1988 reserves. As of December 31, 1997, the pre-1988 reserves of the
Association for tax purposes totaled approximately $832,000. The Association
believes it had approximately $4.3 million of accumulated earnings and profits
for tax purposes as of December 31, 1997, which would be available for dividend
distributions, provided regulatory restrictions applicable to the payment of
dividends are met. See Notes 6 and 15 to the financial statements. No
representation can be made as to whether the Association will have current or
accumulated earnings and profits in subsequent years.

         The tax returns of the Association have been audited or closed without
audit through fiscal year 1992. In the opinion of management, any examination of
open returns would not result in a deficiency which could have a material
adverse effect on the financial condition of the Association .

OHIO TAXATION

         OSFS is subject to the Ohio corporation franchise tax, which, as
applied to OSFS, is a tax measured by both net earnings and net worth. The rate
of tax is the greater of (i) 5.1% on the first $50,000 of computed Ohio taxable
income and 8.9% of computed Ohio taxable income in excess of $50,000 or (ii)
0.582% times taxable net worth. For tax years beginning after December 31, 1998,
the rate of tax is the greater of (i) 5.1% on the first $50,000 of computed Ohio
taxable income and 8.5% of computed Ohio taxable income in excess of $50,000 or
(ii) .400% times taxable net worth.

         In computing its tax under the net worth method, OSFS may exclude 100%
of its investment in the capital stock of the Association , as reflected on the
balance sheet of OSFS in computing its taxable net worth as long as it owns at
least 25% of the issued and outstanding capital stock of the Association . The
calculation of the exclusion from net worth is based on the ratio of the
excludable investment (net of any appreciation or goodwill included in such
investment) to total assets multiplied by the net value of the stock. As a
holding company, OSFS may be entitled to various other deductions in computing
taxable net worth that are not generally available to operating companies.

         A special litter tax is also applicable to all corporations, including
OSFS, subject to the Ohio corporation franchise tax other than "financial
institutions." If the franchise tax is paid on the net income basis, the litter
tax is equal to .11% of the first $50,000 of computed Ohio taxable income and
 .22% of computed Ohio taxable income in excess of $50,000. If the franchise tax
is paid on the net worth basis, the litter tax is equal to .014% times taxable
net worth.

         The Association is a "financial institution" for State of Ohio tax
purposes. As such, it is subject to the Ohio corporate franchise tax on
"financial institutions," which is imposed annually at a rate of 1.5% of the
book net worth of the Association determined in accordance with generally
accepted accounting principles. For tax year 1999, however, the franchise tax on
financial institutions will be 1.4% of the book net worth and for tax year 2000
and years thereafter the tax


                                      -22-
<PAGE>   24

will be 1.3% of the book net worth. As a "financial institution," the
Association is not subject to any tax based upon net income or net profits
imposed by the State of Ohio.
