FACTS ABOUT CONVERSION

The Board of Directors of Bridgeport Savings and Loan Association ("Bridgeport
Savings") unanimously adopted a Plan of Conversion to convert from an Ohio
mutual savings and loan association to an Ohio capital stock savings and loan
association (the "Conversion").

This brochure answers some of the most frequently asked questions about the
Conversion and about your opportunity to invest in common shares of Ohio State
Financial Services, Inc., (the "Holding Company"), the newly formed corporation
that will become the holding company for Bridgeport Savings following the
Conversion.

Investment in the common shares of Ohio State Financial Services, Inc. involves
certain risks. For a discussion of these risks and other factors, including a
complete description of the offering, INVESTORS ARE URGED TO READ THE
ACCOMPANYING PROSPECTUS, especially the discussion under the heading "Risk
Factors" on page x.

WHY IS BRIDGEPORT SAVINGS 
CONVERTING TO STOCK FORM? 
- --------------------------------------------------------------------------------
The stock form of ownership is used by most business corporations and an
increasing number of savings institutions. Through the sale of stock, Bridgeport
Savings will raise additional capital enabling it to:

     -      support and expand its current financial and other services.

     -      allow customers and friends to purchase common shares and share in
            the Holding Company's and Bridgeport Saving's future.

WILL THE CONVERSION AFFECT ANY OF MY
DEPOSIT ACCOUNTS OR LOANS?
- --------------------------------------------------------------------------------
No. The Conversion will have no effect on the balance or terms of any savings
account or loan, and your deposits will continue to be federally insured by the
Federal Deposit Insurance Corporation ("FDIC") to the maximum legal limit. YOUR
SAVINGS ACCOUNT IS NOT BEING CONVERTED TO STOCK.

ACCOUNT?

However, no assurance can be given that an active and liquid market will
develop.

Dear Member:

         We are pleased to announce that Bridgeport Savings and Loan Association
is converting from an Ohio mutual savings and loan association to an Ohio
capital stock savings and loan association (the "Conversion"). In conjunction
with the Conversion, Ohio State Financial Services, Inc., the newly-formed
corporation that will become the holding company for Bridgeport Savings, is
offering common shares in a subscription offering and a community offering.

         Unfortunately, Ohio State Financial Services, Inc. is unable to either
offer or sell its common shares to you because the small number of eligible
subscribers in your jurisdiction makes registration or qualification of the
common shares under the securities laws of your jurisdiction impractical, for
reasons of cost or otherwise. Accordingly, this letter should not be considered
an offer to sell or a solicitation of an offer to buy the common shares of Ohio
State Financial Services, Inc.

         However, as a member of Bridgeport Savings, you have the right to vote
on the Plan of Conversion at the Special Meeting of Members to be held on XXXX
xx, 1997. Therefore, enclosed is a proxy card, a Proxy Statement (which includes
the Notice of the Special Meeting), a Prospectus (which contains information
incorporated into the Proxy Statement) and a return envelope for your proxy
card.

whether or not you are able to attend, please complete the enclosed proxy card
and return it in the enclosed envelope.
