Comptroller of the Currency. Upon consummation of the Subsidiary Merger, the
separate corporate existence of FFB shall cease and MAB shall survive and
continue to exist as a national banking association (MAB, as the resulting bank
in the Subsidiary Merger, sometimes being referred to herein as the "Resulting
Bank"). SFG may, at any time prior to the Effective Date, convert the charter of
MAB to an Ohio state-chartered bank, in its sole discretion. In such event, the
Subsidiary Merger will be implemented in accordance with applicable Ohio banking
laws. (The Parent Merger and the Subsidiary Merger shall sometimes collectively
be referred to as the "Merger".)

         2.03 CERTIFICATE OF PARENT MERGER. Subject to the satisfaction or
waiver of the conditions set forth in Article VII, the Parent Merger shall
become effective upon the occurrence of the filing in the office of the DSS and
the OSS of a certificate of merger in accordance with Section 252 of the DGCL
and Section 1701.81 of the OGCL or such later date and time as may be set forth
in such certificate. The Parent Merger shall have the effects prescribed in the
DGCL and the OGCL.

         2.04 EFFECTIVE DATE AND EFFECTIVE TIME. Subject to the satisfaction or
waiver of the conditions set forth in Article VII, the parties shall cause the
effective date of the Parent Merger (the "Effective Date") to occur on (i) the
fifth business day to occur after the last of the conditions set forth in
Article VII shall have been satisfied or waived in accordance with the terms of
this Agreement (or, at the election of SFG, on the last business day of the
month in which such fifth business day occurs or, if such fifth business day
occurs within the last five business days of such month, on the last business
day of the succeeding month; provided, no such

election shall cause the Effective Date to fall after the date specified in
Section 8.01 (c) hereof or after the date or dates on which any Regulatory
Authority approval or any extension thereof expires, or (ii) such other date to
which the parties may agree in writing. In no event will the Effective Date
occur earlier than May 1, 1999. The time on the Effective Date when the Parent
Merger shall become effective is referred to as the "Effective Time."


                                   ARTICLE III

                       CONSIDERATION; EXCHANGE PROCEDURES

         3.01 MERGER CONSIDERATION. Subject to the provisions of this Agreement,
at the Effective Time, automatically by virtue of the Parent Merger and without
any action on the part of any Person:

         (a) Outstanding WBI Common Stock and WBI Rights. Each share, excluding
     Treasury Stock and Dissenting Shares, of WBI Common Stock issued and
     outstanding immediately prior to the Effective Time shall become and be
     converted into .7315 of a share of SFG Common Stock (the "Exchange Ratio").
     The Exchange Ratio shall be subject to adjustment as set forth in Section
     3.05.

         (b) Treasury Shares. Each share of WBI Common Stock held as Treasury
     Stock immediately prior to the Effective Time shall be canceled and retired
     at the Effective Time and no consideration shall be issued in exchange
     therefor.

         (c) Dissenting Shares. Dissenting Shares shall not be exchanged for SFG
     Common Stock but rather shall be entitled to the rights set forth in
     Section 262 of the DGCL. Notwithstanding any other provision of this
     Agreement, any Dissenting Shares shall not, after the Effective Time, be
     entitled to vote for any purpose or receive any dividends or other
     distributions (except dividends or other distributions payable to
     stockholders of record of WBI at a date which is prior to the Effective
     Date) and shall be entitled only to such rights as are afforded in respect
     of Dissenting Shares pursuant to the DGCL.

         (d) Outstanding SFG Stock. Each share of SFG Common Stock issued and
     outstanding immediately prior to the Effective Time shall remain issued and
     outstanding and unaffected by the Parent Merger.

         3.02 RIGHTS AS STOCKHOLDERS; STOCK TRANSFERS. At the Effective Time,
holders of WBI Common Stock shall cease to be, and shall have no rights as,
stockholders of WBI, other than to receive any dividend or other distribution
with respect to such WBI Common Stock with a record date occurring prior to the
Effective Time and the consideration provided under this Article III, and
appraisal rights in the case of Dissenting Shares. After the Effective Time,
there shall be no transfers on the stock transfer books of WBI of shares of WBI
Stock.

                                       8
<PAGE>   12

         3.03 FRACTIONAL SHARES. Notwithstanding any other provision hereof, no
fractional shares of SFG Common Stock and no certificates or scrip therefor, or
other evidence of ownership thereof, will be issued in the Parent Merger;
instead, SFG shall pay to each holder of WBI Common Stock who would otherwise be
entitled to a fractional share of SFG Common Stock (after taking into account
all Old Certificates delivered by such holder) an amount in cash (without
interest) determined by multiplying such fractional share of SFG Common Stock to
which the holder would be entitled by the last sale price of SFG Common Stock,
as reported by the NASDAQ (as reported in The Wall Street Journal or, if not
reported therein, in another authoritative source), for the NASDAQ trading day
immediately preceding the Effective Date.

         3.04 EXCHANGE PROCEDURES. (a) At or prior to the Effective Time, SFG
shall deposit, or shall cause to be deposited, with Bank of New York (in such
capacity, the "Exchange Agent"), for the benefit of the holders of certificates
formerly representing shares of WBI Common Stock ("Old Certificates"), for
exchange in accordance with this Article III, certificates representing the
shares of SFG Common Stock ("New Certificates") and an estimated amount of cash
(such cash and New Certificates, together with any dividends or distributions
with a record date occurring on or after the Effective Date with respect thereto
(without any interest on any such cash, dividends or distributions), being
hereinafter referred to as the "Exchange Fund") to be paid pursuant to this
Article III in exchange for outstanding shares of WBI Common Stock.

         (b) As promptly as practicable after the Effective Date, SFG shall send
     or cause to be sent to each former holder of record of shares of WBI Common
     Stock immediately prior to the Effective Time transmittal materials for use
     in exchanging such stockholder's Old Certificates for the consideration set
     forth in this Article III. SFG shall cause the New Certificates into which
     shares of a stockholder's WBI Common Stock are converted on the Effective
     Date and/or any check in respect of any fractional share interests or
     dividends or distributions which such person shall be entitled to receive
     to be delivered to such stockholder upon delivery to the Exchange Agent of
     Old Certificates representing such shares of WBI Common Stock (or indemnity
     reasonably satisfactory to SFG and the Exchange Agent, if any of such
     certificates are lost, stolen or destroyed) owned by such stockholder. No
     interest will be paid on any such cash to be paid in lieu of fractional
     share interests or in respect of dividends or distributions which any such
     person shall be entitled to receive pursuant to this Article III upon such
     delivery.

         (c) Notwithstanding the foregoing, neither the Exchange Agent, if any,
     nor any party hereto shall be liable to any former holder of WBI Stock for
     any amount properly delivered to a public official pursuant to applicable
     abandoned property, escheat or similar laws.

         (d) No dividends or other distributions with respect to SFG Common
     Stock with a record date occurring on or after the Effective Date shall be
     paid to the holder of any unsurrendered Old Certificate representing shares
     of WBI Common Stock converted in the Parent Merger into the right to
     receive shares of such SFG Common Stock until the holder 



                                       9
<PAGE>   13

     thereof shall be entitled to receive New Certificates in exchange therefor
     in accordance with the procedures set forth in this Section 3.04. After
     becoming so entitled in accordance with this Section 3.04, the record
     holder thereof also shall be entitled to receive any such dividends or
     other distributions, without any interest thereon, which theretofor had
     become payable with respect to shares of SFG Common Stock such holder had
     the right to receive upon surrender of the Old Certificates.

         (e) Any portion of the Exchange Fund that remains unclaimed by the
     stockholders of WBI for six months after the Effective Time shall be paid
     to SFG. Any stockholders of WBI who have not theretofor complied with this
     Article III shall thereafter look only to SFG for payment of the shares of
     SFG Common Stock, cash in lieu of any fractional shares and unpaid
     dividends and distributions on SFG Common Stock deliverable in respect of
     each share of WBI Common Stock such stockholder holds as determined
     pursuant to this Agreement, in each case, without any interest thereon.

         3.05 ANTI-DILUTION PROVISIONS. In the event SFG changes (or establishes
a record date for changing) the number of shares of SFG Common Stock issued and
outstanding between the date hereof and the Effective Date as a result of a
stock split, stock dividend, recapitalization, reclassification, split up,
combination, exchange of shares, readjustment or similar transaction with
respect to the outstanding SFG Common Stock and the record date therefor shall
be prior to the Effective Date, the Exchange Ratio shall be proportionately
adjusted.

         3.06 OPTIONS. (a) At the Effective Time, each outstanding option to
purchase shares of WBI Common Stock under the WBI Stock Plans (each, a "WBI
Stock Option"), whether vested or unvested, shall be converted into an option to
acquire, on the same terms and conditions as were applicable under such WBI
Stock Option, the number of shares of SFG Common Stock equal to (a) the number
of shares of WBI Common Stock subject to the WBI Stock Option, multiplied by (b)
the Exchange Ratio (such product rounded to the nearest whole number) (a
"Replacement Option"), at an exercise price per share (rounded to the nearest
whole cent) equal to (y) the aggregate exercise price for the shares of WBI
Common Stock which were purchasable pursuant to such WBI Stock Option divided by
(z) the number of full shares of SFG Common Stock subject to such Replacement
Option in accordance with the foregoing. Notwithstanding the foregoing, each WBI
Stock Option which is intended to be an "incentive stock option" (as defined in
Section 422 of the Code) shall be adjusted in accordance with the requirements
of Section 424 of the Code. At or prior to the Effective Time, WBI shall use its
best efforts, including using its best efforts to obtain any necessary consents
from optionees, with respect to the WBI Stock Plans to permit the replacement of
the outstanding WBI Stock Options by SFG pursuant to this Section and to permit
SFG to assume the WBI Stock Plans. WBI shall further take all action necessary
to amend the WBI Stock Plans to eliminate automatic grants or awards thereunder
following the Effective Time. At the Effective Time, SFG shall assume the WBI
Stock Plans; provided, that such assumption shall be only in respect of the
Replacement Options and that SFG shall have no obligation with respect to any
awards under the WBI Stock Plans other than the Replacement Options and shall
have no obligation to make any additional grants or 



                                       10
<PAGE>   14

awards under such assumed WBI Stock Plans.

         (b) At all times after the Effective Time, SFG shall reserve for
     issuance such number of shares of SFG Common Stock as necessary so as to
     permit the exercise of the Replacement Options in the manner contemplated
     by this Agreement and the instruments pursuant to which the corresponding
     WBI Stock Options were granted. SFG shall make all filings required under
     federal and state securities laws no later than the Effective Time so as to
     permit the exercise of such options and the sale of the shares received by
     the optionee upon such exercise at and after the Effective Time and SFG
     shall continue to make such filings thereafter as may be necessary to
     permit the continued exercise of options and subsequent sale of such
     shares.

     this Agreement.

                         REPRESENTATIONS AND WARRANTIES

         5.01 DISCLOSURE SCHEDULES. On or prior to the date hereof, SFG has
delivered to WBI a schedule and WBI has delivered to SFG a schedule
(respectively, its "Disclosure Schedule") setting forth, among other things,
items the disclosure of which is necessary or appropriate either in response to
an express disclosure requirement contained in a provision hereof or as an
exception to one or more representations or warranties contained in Section 5.03
or 5.04 or to one or more of its covenants contained in Article IV; provided,
that (a) no such item is required to be set forth in a Disclosure Schedule as an
exception to a representation or warranty if its absence would not be reasonably
likely to result in the related representation or warranty being deemed untrue
or incorrect under the standard established by Section 5.02, and (b) the mere
inclusion of an item in a Disclosure Schedule as an exception to a
representation or warranty shall not be deemed an admission by a party that such
item represents a material exception or fact, event or circumstance or that such
item is reasonably likely to result in a Material Adverse Effect on the party
making the representation. WBI's representations, warranties and covenants
contained in this Agreement shall not be deemed to be untrue or breached as a
result of effects arising solely from actions taken in compliance with a written
request of SFG.



                                       14
<PAGE>   18

         5.02 STANDARD. No representation or warranty of WBI or SFG contained in
Section 5.03 or 5.04 shall be deemed untrue or incorrect, and no party hereto
shall be deemed to have breached a representation or warranty, as a consequence
of the existence of any fact, event or circumstance unless such fact,
circumstance or event, individually or taken together with all other facts,
events or circumstances inconsistent with any representation or warranty
contained in Section 5.03 or 5.04 has had, or is reasonably likely to have, a
Material Adverse Effect. For purposes of this Agreement, "knowledge" shall mean,
with respect to a party hereto, actual knowledge of any officer of that party
with the title of not less than senior vice president and that party's in-house
counsel, if any.

         5.03 REPRESENTATIONS AND WARRANTIES OF WBI. Subject to Sections 5.01

     shares of WBI Common Stock have been duly authorized and are validly issued
     and outstanding, fully paid and nonassessable, and subject to no preemptive
     rights (and were not issued in violation of any preemptive rights). As of

     there are no shares of WBI Common Stock authorized and reserved for
     issuance, WBI does not have any Rights issued or outstanding with respect
     to WBI Common Stock, and WBI does not have any commitment to authorize,
     issue or sell any WBI Common Stock or Rights, except pursuant to this
     Agreement and the Stock Option Agreement. The number of shares of WBI
     Common Stock which are issuable and reserved for issuance upon exercise of
     WBI Stock Options as of the date hereof are Previously Disclosed in WBI's
     Disclosure Schedule.

     outstanding equity securities of each of its Subsidiaries, (C) no equity

     issued (other than to it or its wholly-owned Subsidiaries) by reason of any
     Right or otherwise, (D) there are no contracts, commitments, understandings
     or arrangements by which any of such Subsidiaries is or may be bound to

     contracts, commitments, understandings, or arrangements relating to its
     rights to vote or to dispose of such securities and (F) all the equity

         in a partnership or joint venture of any kind, other than its
         Subsidiaries.

              (iii) Each of WBI's Subsidiaries has been duly organized and is

         its organization, and is duly qualified to do business and in good
         standing in the jurisdictions where its ownership or leasing of
         property or the conduct of its business requires it to be so qualified.

         (d) Corporate Power. Each of WBI and its Subsidiaries has the corporate
     power and authority to carry on its business as it is now being conducted
     and to own all its properties and assets; WBI has the corporate power and
     authority to execute, deliver and perform its obligations under this
     Agreement and the Stock Option Agreement; and FFB has the corporate power
     and authority to consummate the Subsidiary Merger in accordance with the
     terms of this Agreement.

         (e) Corporate Authority. Subject in the case of this Agreement to
     receipt of the requisite adoption of this Agreement by the holders of a
     majority of the outstanding shares of WBI Common Stock entitled to vote
     thereon (which is the only stockholder vote required thereon), this
     Agreement, the Stock Option Agreement and the transactions contemplated
     hereby and thereby have been authorized by all necessary corporate action
     of WBI and the WBI Board prior to the date hereof. The Agreement to Merge,
     when executed by FFB, shall have been approved by the Board of Directors of
     FFB and by the WBI Board, as the sole stockholder of FFB. This Agreement is
     a valid and legally binding obligation of WBI, enforceable in accordance
     with its terms (except as enforceability may be limited by applicable
     bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer and
     similar laws of general applicability relating to or affecting creditors'
     rights or by general equity principles). The WBI Board has received the
     written opinion of Stifel, Nicholaus & Company, Incorporated to the effect
     that as of the date hereof the consideration to be received by the holders
     of WBI Common Stock in the Parent Merger is fair to the holders of WBI
     Common Stock from a financial point of view.

         (f) Regulatory Filings; No Defaults. (i) No consents or approvals of,
     or filings or registrations with, any Governmental Authority or with any
     third party are required to be made or obtained by WBI or any of its
     Subsidiaries in connection with the execution, delivery or performance by
     WBI of this Agreement or the Stock Option Agreement or to consummate the
     Merger except for (A) filings of applications, notices and the Agreement to
     Merge, as applicable, with federal and state thrift and banking
     authorities, (B) filings with the SEC and state securities authorities, and
     (C) the filing of the certificate of merger with the DSS pursuant to the
     DGCL and the OSS pursuant to the OGCL. As of the date hereof, WBI is not
     aware of any reason why the approvals set forth in Section 7.01(b) will not
     be received without the imposition of a condition, restriction or
     requirement of the type described in Section 7.01(b).

              (ii) Subject to receipt of the regulatory and stockholder
         approvals referred to above and expiration of related regulatory
         waiting periods, and required filings under federal and state
         securities laws, the execution, delivery and performance of this
         Agreement and the Stock Option Agreement and the consummation of the
         transactions contemplated hereby and thereby do not and will not (A)
         constitute a breach or violation of, or a default under, or give rise
         to any Lien, any acceleration of remedies or any right of termination
         under, any law, rule or regulation or any judgment, decree, order,
         governmental permit or license, or agreement, indenture or instrument
         of WBI or of any of its Subsidiaries or to which WBI or any of its
         Subsidiaries or properties is subject or bound, (B) constitute a breach
         or violation of, or a default under, the WBI Certificate or the WBI
         By-Laws, or (C) require any consent or approval under any such law,
         rule, regulation, judgment, decree, order, governmental permit or
         license, agreement, indenture or instrument.

         (g) Financial Reports and SEC Documents. (i) WBI's Annual Reports on
     Form 10-KSB for the fiscal years ended June 30, 1996, 1997 and 1998 and all
     other reports, registration statements, definitive proxy statements or
     information statements filed or to be filed by it or any of its
     Subsidiaries subsequent to June 30, 1996 under the Securities Act, or under
     Section 13(a), 13(c), 14 or 15(d) of the Exchange Act, in the form filed or
     to be filed (collectively, "WBI SEC Documents") with the SEC, as of the
     date filed, (A) complied or will comply in all material respects with the
     applicable requirements under the Securities Act or the Exchange Act, as
     the case may be, and (B) did not and will not contain any untrue statement
     of a material fact or omit to state a material fact required to be stated
     therein or necessary to make the statements therein, in light of the
     circumstances under which they were made, not misleading; and each of the
     balance sheets or statements of condition contained in or incorporated by
     reference into any such WBI SEC Document (including the related notes and
     schedules thereto) fairly presents, or will fairly present, the financial
     position of WBI and its Subsidiaries as of its date, and each of the
     statements of income and changes in stockholders' equity and cash flows or
     equivalent statements in such WBI SEC Documents (including any related
     notes and schedules thereto) fairly presents, or will fairly present, the
     results of operations, changes in stockholders' equity and cash flows, as
     the case may be, of 



                                       17
<PAGE>   21

     WBI and its Subsidiaries for the periods to which they relate, in each case
     in accordance with generally accepted accounting principles consistently
     applied during the periods involved, except in each case as may be noted
     therein, subject to normal year-end audit adjustments and the absence of
     footnotes in the case of unaudited statements.

              (ii) Since June 30, 1998, WBI and its Subsidiaries have not
         incurred any material liability not disclosed in any WBI SEC Document
         other than in the ordinary course of business consistent with past
         practice.

              (iii) Since June 30, 1998, (A) WBI and its Subsidiaries have
         conducted their respective businesses in the ordinary and usual course
         consistent with past practice (excluding matters related to this
         Agreement and the transactions contemplated hereby) and (B) no event
         has occurred or circumstance arisen that, individually or taken
         together with all other facts, circumstances and events (described in
         any paragraph of Section 5.03 or otherwise), is reasonably likely to
         have a Material Adverse Effect with respect to WBI.

         (h) Litigation. No litigation, claim or other proceeding before any
     court or governmental agency is pending against WBI or any of its
     Subsidiaries and, to WBI's knowledge, no such litigation, claim or other
     proceeding has been threatened.

         (i) Regulatory Matters.

              (i) Neither WBI nor any of its Subsidiaries or properties is a
         party to or is subject to any order, decree, agreement, memorandum of
         understanding or similar arrangement with, or a commitment letter or
         similar submission to, or extraordinary supervisory letter from, any
         federal or state governmental agency or authority charged with the
         supervision or regulation of financial institutions (or their holding
         companies) or issuers of securities or engaged in the insurance of
         deposits (including, without limitation, the Office of the Comptroller
         of the Currency, the Office of Thrift Supervision, the Federal Reserve
         System and the FDIC) or the supervision or regulation of it or any of
         its Subsidiaries (collectively, the "Regulatory Authorities").

              (ii) Neither it nor any of its Subsidiaries has been advised by
         any Regulatory Authority that such Regulatory Authority is
         contemplating issuing or requesting (or is considering the
         appropriateness of issuing or requesting) any such order, decree,
         agreement, memorandum of understanding, commitment letter, supervisory
         letter or similar submission.

         (j) Compliance with Laws. Each of WBI and its Subsidiaries:

              (i) is in compliance with all applicable federal, state, local and
         foreign statutes, laws, regulations, ordinances, rules, judgments,
         orders or decrees applicable thereto or to the employees conducting
         such businesses, including, without limitation, the Equal Credit



                                       18
<PAGE>   22

         Opportunity Act, the Fair Housing Act, the Community Reinvestment Act,
         the Home Mortgage Disclosure Act and all other applicable fair lending
         laws and other laws relating to discriminatory business practices;

              (ii) has all permits, licenses, authorizations, orders and
         approvals of, and has made all filings, applications and registrations
         with, all Governmental Authorities that are required in order to permit
         them to own or lease their properties and to conduct their businesses
         as presently conducted; all such permits, licenses, certificates of
         authority, orders and approvals are in full force and effect and, to
         WBI's knowledge, no suspension or cancellation of any of them is
         threatened; and

              (iii) has received, since June 30, 1998, no notification or
         communication from any Governmental Authority (A) asserting that WBI or
         any of its Subsidiaries is not in compliance with any of the statutes,
         regulations, or ordinances which such Governmental Authority enforces
         or (B) threatening to revoke any license, franchise, permit, or
         governmental authorization (nor, to WBI's knowledge, do any grounds for
         any of the foregoing exist).

         (k) Material Contracts; Defaults. Except for this Agreement, the Stock
     Option Agreement, those agreements and other documents filed as exhibits to
     the WBI SEC Documents, neither it nor any of its Subsidiaries is a party
     to, bound by or subject to any agreement, contract, arrangement, commitment
     or understanding (whether written or oral) (i) that is a "material
     contract" within the meaning of Item 601(b)(10) of the SEC's Regulation S-K
     or (ii) that restricts or limits in any way the conduct of business by it
     or any of its Subsidiaries (including without limitation a non-compete or
     similar provision). Neither it nor any of its Subsidiaries is in default
     under any contract, agreement, commitment, arrangement, lease, insurance
     policy or other instrument to which it is a party, by which its respective
     assets, business, or operations may be bound or affected in any way, or
     under which it or its respective assets, business, or operations receive
     benefits, and there has not occurred any event that, with the lapse of time
     or the giving of notice or both, would constitute such a default.

         (l) No Brokers. No action has been taken by WBI that would give rise to
     any valid claim against any party hereto for a brokerage commission,
     finder's fee or other like payment with respect to the transactions
     contemplated by this Agreement, excluding a Previously Disclosed fee to be
     paid to Stifel, Nicolaus & Company, Incorporated.

         (m) Employee Benefit Plans. (i) Section 5.03(m)(i) of WBI's Disclosure
     Schedule contains a complete and accurate list of all existing bonus,
     incentive, deferred compensation, pension, retirement, profit-sharing,
     thrift, savings, employee stock ownership, stock bonus, stock purchase,
     restricted stock, stock option, severance, welfare and fringe benefit
     plans, employment or severance agreements and all similar practices,
     policies and arrangements in which any employee or former employee (the
     "Employees"), consultant or former consultant 


                                       19
<PAGE>   23

     (the "Consultants") or director or former director (the "Directors") of WBI
     or any of its Subsidiaries participates or to which any such Employees,
     Consultants or Directors are a party (the "Compensation and Benefit
     Plans"). Neither WBI nor any of its Subsidiaries has any commitment to
     create any additional Compensation and Benefit Plan or to modify or change
     any existing Compensation and Benefit Plan.

              (ii) Each Compensation and Benefit Plan has been operated and
         administered in all material respects in accordance with its terms and
         with applicable law, including, but not limited to, ERISA, the Code,
         the Securities Act, the Exchange Act, the Age Discrimination in
         Employment Act, or any regulations or rules promulgated thereunder, and
         all filings, disclosures and notices required by ERISA, the Code, the
         Securities Act, the Exchange Act, the Age Discrimination in Employment
         Act and any other applicable law have been timely made. Each
         Compensation and Benefit Plan which is an "employee pension benefit
         plan" within the meaning of Section 3(2) of ERISA (a "Pension Plan")
         and which is intended to be qualified under Section 401(a) of the Code
         has received a favorable determination letter (including a
         determination that the related trust under such Compensation and
         Benefit Plan is exempt from tax under Section 501(a) of the Code) from
         the Internal Revenue Service ("IRS"), and WBI is not aware of any
         circumstances likely to result in revocation of any such favorable
         determination letter. There is no material pending or, to the knowledge
         of WBI, threatened legal action, suit or claim relating to the
         Compensation and Benefit Plans. Neither WBI nor any of its Subsidiaries
         has engaged in a transaction, or omitted to take any action, with
         respect to any Compensation and Benefit Plan that would reasonably be
         expected to subject WBI or any of its Subsidiaries to a tax or penalty
         imposed by either Section 4975 of the Code or Section 502 of ERISA,
         assuming for purposes of Section 4975 of the Code that the taxable
         period of any such transaction expired as of the date hereof.

              (iii) No liability (other than for payment of premiums to the PBGC
         which have been made or will be made on a timely basis) under Title IV
         of ERISA has been or is expected to be incurred by WBI or any of its
         Subsidiaries with respect to any ongoing, frozen or terminated
         "single-employer plan", within the meaning of Section 4001(a)(15) of
         ERISA, currently or formerly maintained by any of them, or any
         single-employer plan of any entity (an "ERISA Affiliate") which is
         considered one employer with WBI under Section 4001(a)(14) of ERISA or
         Section 414(b) or (c) of the Code (an "ERISA Affiliate Plan"). None of
         WBI, any of its Subsidiaries or any ERISA Affiliate has contributed, or
         has been obligated to contribute, to a multiemployer plan under
         Subtitle E of Title IV of ERISA at any time since September 26, 1980.
         No notice of a "reportable event", within the meaning of Section 4043
         of ERISA for which the 30-day reporting requirement has not been
         waived, has been required to be filed for any Compensation and Benefit
         Plan or by any ERISA Affiliate Plan within the 12-month period ending
         on the date hereof, and no such notice will be required to be filed as
         a result of the transactions contemplated by this Agreement. The PBGC
         has not instituted proceedings to terminate any Pension Plan or ERISA
         Affiliate Plan and, to WBI's knowledge, no condition exists that
         presents a 



                                       20
<PAGE>   24

         material risk that such proceedings will be instituted. To the
         knowledge of WBI, there is no pending investigation or enforcement
         action by the PBGC, the Department of Labor (the "DOL") or IRS or any
         other governmental agency with respect to any Compensation and Benefit
         Plan. Under each Pension Plan and ERISA Affiliate Plan, as of the date
         of the most recent actuarial valuation performed prior to the date of
         this Agreement, the actuarially determined present value of all
         "benefit liabilities", within the meaning of Section 4001(a)(16) of
         ERISA (as determined on the basis of the actuarial assumptions
         contained in such actuarial valuation of such Pension Plan or ERISA
         Affiliate Plan), did not exceed the then current value of the assets of
         such Pension Plan or ERISA Affiliate Plan and since such date there has
         been neither an adverse change in the financial condition of such
         Pension Plan or ERISA Affiliate Plan nor any amendment or other change
         to such Pension Plan or ERISA Affiliate Plan that would increase the
         amount of benefits thereunder which reasonably could be expected to
         change such result.

              (iv) All contributions required to be made under the terms of any
         Compensation and Benefit Plan or ERISA Affiliate Plan or any employee
         benefit arrangements under any collective bargaining agreement to which
         WBI or any of its Subsidiaries is a party have been timely made or have
         been reflected on WBI's financial statements. Neither any Pension Plan
         nor any ERISA Affiliate Plan has an "accumulated funding deficiency"
         (whether or not waived) within the meaning of Section 412 of the Code
         or Section 302 of ERISA and all required payments to the PBGC with
         respect to each Pension Plan or ERISA Affiliate Plan have been made on
         or before their due dates. None of WBI, any of its Subsidiaries or any
         ERISA Affiliate (x) has provided, or would reasonably be expected to be
         required to provide, security to any Pension Plan or to any ERISA
         Affiliate Plan pursuant to Section 401(a)(29) of the Code, and (y) has
         taken any action, or omitted to take any action, that has resulted, or
         would reasonably be expected to result, in the imposition of a lien
         under Section 412(n) of the Code or pursuant to ERISA.

              (v) Neither WBI nor any of its Subsidiaries has any obligations to
         provide retiree health and life insurance or other retiree death
         benefits under any Compensation and Benefit Plan, other than benefits
         mandated by Section 4980B of the Code, and each such Compensation and
         Benefit Plan may be amended or terminated without incurring liability
         thereunder. There has been no communication to Employees by WBI or any
         of its Subsidiaries that would reasonably be expected to promise or
         guarantee such Employees retiree health or life insurance or other
         retiree death benefits on a permanent basis.

              (vi) WBI and its Subsidiaries do not maintain any Compensation and
         Benefit Plans covering foreign Employees.

              (vii) With respect to each Compensation and Benefit Plan, if
         applicable, WBI has provided or made available to SFG, true and
         complete copies of existing: (A) Compensation and Benefit Plan
         documents and amendments thereto; (B) trust instruments and insurance
         contracts; (C) two most recent Forms 5500 filed with the IRS; 


                                       21
<PAGE>   25

         (D) most recent actuarial report and financial statement; (E) the most
         recent summary plan description; (F) forms filed with the PBGC (other
         than for premium payments); (G) most recent determination letter issued
         by the IRS; (H) any Form 5310 or Form 5330 filed with the IRS; and (I)
         most recent nondiscrimination tests performed under ERISA and the Code
         (including 401(k) and 401(m) tests).

              (viii) Except as disclosed on Section 5.03(m)(viii) of WBI's
         Disclosure Schedule, the consummation of the transactions contemplated
         by this Agreement would not, directly or indirectly (including, without
         limitation, as a result of any termination of employment prior to or
         following the Effective Time) reasonably be expected to (A) entitle any
         Employee, Consultant or Director to any payment (including severance
         pay or similar compensation) or any increase in compensation, (B)
         result in the vesting or acceleration of any benefits under any
         Compensation and Benefit Plan or (C) result in any material increase in
         benefits payable under any Compensation and Benefit Plan.

              (ix) Except as disclosed on Section 5.03(m)(ix) of WBI's
         Disclosure Schedule, neither WBI nor any of its Subsidiaries maintains
         any compensation plans, programs or arrangements the payments under
         which would not reasonably be expected to be deductible as a result of
         the limitations under Section 162(m) of the Code and the regulations
         issued thereunder.

              (x) Except as disclosed on Section 5.03(m)(x) of WBI's Disclosure
         Schedule, as a result, directly or indirectly, of the transactions
         contemplated by this Agreement (including, without limitation, as a
         result of any termination of employment prior to or following the
         Effective Time), none of SFG or WBI, or any of their respective
         Subsidiaries, will be obligated to make a payment that would be
         characterized as an "excess parachute payment" to an individual who is
         a "disqualified individual" (as such terms are defined in Section 280G
         of the Code)of WBI on a consolidated basis, without regard to whether
         such payment is reasonable compensation for personal services performed
         or to be performed in the future.

         (n) Labor Matters. Neither WBI nor any of its Subsidiaries is a party
     to or is bound by any collective bargaining agreement, contract or other
     agreement or understanding with a labor union or labor organization, nor is
     WBI or any of its Subsidiaries the subject of a proceeding asserting that
     it or any such Subsidiary has committed an unfair labor practice (within
     the meaning of the National Labor Relations Act) or seeking to compel WBI
     or any such Subsidiary to bargain with any labor organization as to wages
     or conditions of employment, nor is there any strike or other labor dispute
     involving it or any of its Subsidiaries pending or, to WBI's knowledge,
     threatened, nor is WBI aware of any activity involving its or any of its
     Subsidiaries' employees seeking to certify a collective bargaining unit or
     engaging in other organizational activity.

         (o) Takeover Laws. WBI has taken all action required to be taken by it
     in order to 




                                       22
<PAGE>   26

     exempt this Agreement, the Stock Option Agreement and the transactions
     contemplated hereby and thereby from, and this Agreement, the Stock Option
     Agreement and the transactions contemplated hereby and thereby are exempt
     from, the requirements of any "moratorium", "control share", "fair price",
     "affiliate transaction", "business combination" or other antitakeover laws
     and regulations of any state (collectively, "Takeover Laws") applicable to
     it, including, without limitation, the State of Delaware.

         (p) Environmental Matters. To WBI's knowledge, neither the conduct nor
     operation of WBI or its Subsidiaries nor any condition of any property
     presently or previously owned, leased or operated by any of them
     (including, without limitation, in a fiduciary or agency capacity), or on
     which any of them holds a Lien, violates or violated Environmental Laws and
     to WBI's knowledge, no condition has existed or event has occurred with
     respect to any of them or any such property that, with notice or the
     passage of time, or both, is reasonably likely to result in liability under
     Environmental Laws. To WBI's knowledge, neither WBI nor any of its
     Subsidiaries has received any notice from any person or entity that WBI or
     its Subsidiaries or the operation or condition of any property ever owned,
     leased, operated, or held as collateral or in a fiduciary capacity by any
     of them are or were in violation of or otherwise are alleged to have
     liability under any Environmental Law, including, but not limited to,
     responsibility (or potential responsibility) for the cleanup or other
     remediation of any pollutants, contaminants, or hazardous or toxic wastes,
     substances or materials at, on, beneath, or originating from any such
     property.

         (q) Tax Matters. (i) All Tax Returns that are required to be filed by
     or with respect to WBI and its Subsidiaries have been duly filed, (ii) all
     Taxes shown to be due on the Tax Returns referred to in clause (i) have
     been paid in full, (iii) the Tax Returns referred to in clause (i) have
     been examined by the Internal Revenue Service or the appropriate state,
     local or foreign taxing authority or the period for assessment of the Taxes
     in respect of which such Tax Returns were required to be filed has expired,
     (iv) all deficiencies asserted or assessments made as a result of such
     examinations have been paid in full, (v) no issues that have been raised by
     the relevant taxing authority in connection with the examination of any of
     the Tax Returns referred to in clause (i) are currently pending, and (vi)
     no waivers of statutes of limitation have been given by or requested with
     respect to any Taxes of WBI or its Subsidiaries. WBI has made available to
     SFG true and correct copies of the United States federal income Tax Returns
     filed by WBI and its Subsidiaries for each of the three most recent fiscal
     years ended on or before June 30, 1997. Neither WBI nor any of its
     Subsidiaries has any liability with respect to income, franchise or similar
     Taxes that accrued on or before the end of the most recent period covered
     by the WBI SEC Documents filed prior to the date hereof in excess of the
     amounts accrued with respect thereto that are reflected in the financial
     statements included in WBI' SEC Documents filed on or prior to the date
     hereof. As of the date hereof, neither WBI nor any of its Subsidiaries has
     any reason to believe that any conditions exist that might prevent or
     impede the Parent Merger from qualifying as a reorganization within the
     meaning of Section 368(a) of the Code.

              (ii) No Tax is required to be withheld pursuant to Section 1445 of
         the Code as a result of the transfer contemplated by this Agreement.

              (iii) WBI and its Subsidiaries will not be liable for any taxes as
         a result of any Covered Transaction.

         (r) Risk Management Instruments. All material interest rate swaps,
     caps, floors, option agreements, futures and forward contracts and other
     similar risk management arrangements, whether entered into for WBI' own
     account, or for the account of one or more of WBI' Subsidiaries or their
     customers (all of which are listed on WBI' Disclosure Schedule), were
     entered into (i) in accordance with prudent business practices and all
     applicable laws, rules, regulations and regulatory policies and (ii) with
     counterparties believed to be financially responsible at the time; and each
     of them constitutes the valid and legally binding obligation of WBI or one
     of its Subsidiaries, enforceable in accordance with its terms (except as
     enforceability may be limited by applicable bankruptcy, insolvency,
     reorganization, moratorium, fraudulent transfer and similar laws of general
     applicability relating to or affecting creditors' rights or by general
     equity principles), and is in full force and effect. Neither WBI nor its
     Subsidiaries, nor to WBI' knowledge any other party thereto, is in breach
     of any of its obligations under any such agreement or arrangement.

         (s) Books and Records. The books and records of WBI and its
     Subsidiaries have been fully, properly and accurately maintained in all
     material respects, and there are no material inaccuracies or discrepancies
     of any kind contained or reflected therein and they fairly reflect the
     substance of events and transactions included therein.

         (t) Insurance. WBI's Disclosure Schedule sets forth all of the
     insurance policies, binders, or bonds maintained by WBI or its
     Subsidiaries. WBI and its Subsidiaries are insured with reputable insurers
     against such risks and in such amounts as the management of WBI reasonably
     has determined to be prudent in accordance with industry practices. All
     such insurance policies are in full force and effect; WBI and its
     Subsidiaries are not in material default thereunder; and all claims
     thereunder have been filed in due and timely fashion.

         (u) Accounting Treatment. As of the date hereof, after due inquiry, WBI
     is aware of no reason why the Merger will fail to qualify for
     "pooling-of-interests" accounting treatment.

         (v) Disclosure. The representations and warranties contained in this
     Section 5.03 do not contain any untrue statement of a material fact or omit
     to state any material fact necessary in order to make the statements and
     information contained in this Section 5.03 not misleading.

         (w) Year 2000. Neither WBI nor any of its Subsidiaries has received, or
     has reason to believe that it will receive, a rating of less than

     Examination. WBI has disclosed to SFG a complete and accurate copy of its
     plan, including an estimate of the anticipated associated costs, for

     organized, validly existing and in good standing under the laws of the
     State of Ohio. SFG is duly qualified to do business and is in good standing

     leasing of property or assets or the conduct of its business requires it to
     be so qualified. MAB is a national banking association duly organized,
     validly existing and in good standing under the laws of the United States

     of SFG consists of 160,000,000 shares, of which 150,000,000 shares are SFG
     Common Stock, of which 45,045,733 shares are outstanding as of the date
     hereof, and 10,000,000 shares are SFG serial preferred stock, of which no
     shares are outstanding as of the date hereof. As of the date hereof, except

     issued or outstanding with respect to SFG Common Stock and SFG does not
     have any commitment to authorize, issue or sell any SFG Common Stock or
     Rights, except pursuant to this Agreement. The outstanding shares of SFG
     Common Stock have been duly authorized and are validly issued and
     outstanding, fully paid and nonassessable, and subject to no preemptive
     rights (and were not issued in violation of any preemptive rights).

              (ii) The shares of SFG Common Stock to be issued in exchange for
         shares of WBI Common Stock in the Parent Merger, when issued in
         accordance with the terms of this Agreement, will be duly authorized,
         validly issued, fully paid and nonassessable and subject to no
         preemptive rights.

         (c) Subsidiaries. Each of SFG's Subsidiaries has been duly organized
     and is validly existing in good standing under the laws of the jurisdiction
     of its organization, and is duly qualified to do business and is in good

<PAGE>   29

         (d) Corporate Power. Each of SFG and its Subsidiaries has the corporate
     power and authority to carry on its business as it is now being conducted
     and to own all its properties and assets; and SFG has the corporate power
     and authority to execute, deliver and perform its obligations under this
     Agreement and the Stock Option Agreement and to consummate the transactions
     contemplated hereby and thereby.

         (e) Corporate Authority. This Agreement, the Stock Option Agreement and
     the transactions contemplated hereby and thereby have been authorized by
     all necessary corporate action of SFG and the SFG Board prior to the date
     hereof and no stockholder approval is required on the part of SFG. The
     Agreement to Merge, when executed by MAB, shall have been approved by the
     Board of Directors of MAB and by the SFG Board, as the sole stockholder of
     MAB. This Agreement is a valid and legally binding agreement of SFG,
     enforceable in accordance with its terms (except as enforceability may be
     limited by applicable bankruptcy, insolvency, reorganization, moratorium,
     fraudulent transfer and similar laws of general applicability relating to
     or "affecting creditors" rights or by general equity principles).

         (f) Regulatory Approvals; No Defaults. (i) No consents or approvals of,
     or filings or registrations with, any Governmental Authority or with any
     third party are required to be made or obtained by SFG or any of its
     Subsidiaries in connection with the execution, delivery or performance by
     SFG of this Agreement or to consummate the Merger except for (A) the filing
     of applications, notices, or the Agreement to Merge, as applicable, with
     the federal and state thrift and banking authorities; (B) the filing and
     declaration of effectiveness of the Registration Statement; (C) the filing
     of the certificate of merger with the DSS pursuant to the DGCL and with the
     OSS pursuant to the OGCL; (D) such filings as are required to be made or
     approvals as are required to be obtained under the securities or "Blue Sky"
     laws of various states in connection with the issuance of SFG Common Stock
     in the Parent Merger; and (E) receipt of the approvals set forth in Section
     7.01(b). As of the date hereof, SFG is not aware of any reason why the
     approvals set forth in Section 7.01(b) will not be received without the
     imposition of a condition, restriction or requirement of the type described
     in Section 7.01(b).

              (ii) Subject to the satisfaction of the requirements referred to
         in the preceding paragraph and expiration of the related waiting
         periods, and required filings under federal and state securities laws,
         the execution, delivery and performance of this Agreement and the
         consummation of the transactions contemplated hereby do not and will
         not (A) constitute a breach or violation of, or a default under, or
         give rise to any Lien, any acceleration of remedies or any right of
         termination under, any law, rule or regulation or any judgment, decree,
         order, governmental permit or license, or agreement, indenture or
         instrument of SFG or of any of its Subsidiaries or to which SFG or any
         of its Subsidiaries or properties is subject or bound, (B) constitute a
         breach or violation of, or a default under, the articles of
         incorporation or Code of Regulations (or similar governing documents)
         of SFG or any of its Subsidiaries, or (C) require any consent or
         approval under any such law, rule, regulation, judgment, decree, order,
         governmental permit or license, agreement, indenture or instrument.

     filed (collectively, "SFG SEC Documents") as of the date filed, (A)
     complied or will comply in all material respects with the applicable
     requirements under the Securities Act or the Exchange Act, as the case may
     be, and (B) did not and will not contain any untrue statement of a material
     fact or omit to state a material fact required to be stated therein or
     necessary to make the statements therein, in light of the circumstances
     under which they were made, not misleading; and each of the balance sheets
     or statements of condition contained in or incorporated by reference into
     any such SFG SEC Document (including the related notes and schedules
     thereto) fairly presents, or will fairly present, the financial position of
     SFG and its Subsidiaries as of its date, and each of the statements of
     income or results of operations and changes in stockholders' equity and
     cash flows or equivalent statements in such SFG SEC Documents (including
     any related notes and schedules thereto) fairly presents, or will fairly
     present, the results of operations, changes in stockholders' equity and
     cash flows, as the case may be, of SFG and its Subsidiaries for the periods
     to which they relate, in each case in accordance with generally accepted
     accounting principles consistently applied during the periods involved,
     except in each case as may be noted therein, subject to normal year-end
     audit adjustments in the case of unaudited statements.

              (ii) The Ohio Bank financial statements as of December 31, 1997
         and 1996 and for each of the three years in the period ended December
         31, 1997, (A) complied or will comply in all material respects with
         generally accepted accounting principles, and (B) did not and will not
         contain any untrue statement of a material fact or omit to state a
         material fact required to be stated therein or necessary to make the
         statements therein, in light of the circumstances under which they were
         made, not misleading.

              (iii) Since December 31, 1997, no event has occurred or
         circumstance arisen that, individually or taken together with all other
         facts, circumstances and events (described in any paragraph of Section
         5.04 or otherwise), is reasonably likely to have a Material Adverse
         Effect with respect to SFG.

         (h) Litigation; Regulatory Action. (i) No litigation, claim or other
     proceeding before any Governmental Authority is pending against SFG or any

<PAGE>   31

              (ii) Neither SFG nor any of its Subsidiaries or properties is a
         party to or is subject to any order, decree, agreement, memorandum of
         understanding or similar arrangement with, or a commitment letter or
         similar submission to, or extraordinary supervisory letter from a
         Regulatory Authority, nor has SFG or any of its Subsidiaries been
         advised by a Regulatory Authority that such agency is contemplating
         issuing or requesting (or is considering the appropriateness of issuing
         or requesting) any such order, decree, agreement, memorandum of
         understanding, commitment letter, supervisory letter or similar
         submission.

         (i) Compliance with Laws. Each of SFG and its Subsidiaries:

              (i) is in compliance with all applicable federal, state, local and
         foreign statutes, laws, regulations, ordinances, rules, judgments,
         orders or decrees applicable thereto or to the employees conducting
         such businesses, including, without limitation, the Equal Credit
         Opportunity Act, the Fair Housing Act, the Community Reinvestment Act,
         the Home Mortgage Disclosure Act and all other applicable fair lending
         laws and other laws relating to discriminatory business practices; and

              (ii) has all permits, licenses, authorizations, orders and
         approvals of, and has made all filings, applications and registrations
         with, all Governmental Authorities that are required in order to permit
         them to conduct their businesses substantially as presently conducted;
         all such permits, licenses, certificates of authority, orders and
         approvals are in full force and effect and, to the best of its
         knowledge, no suspension or cancellation of any of them is threatened;
         and

              (iii) has received, since December 31, 1996, no notification or
         communication from any Governmental Authority (A) asserting that SFG or
         any of its Subsidiaries is not in compliance with any of the statutes,
         regulations, or ordinances which such Governmental Authority enforces
         or (B) threatening to revoke any license, franchise, permit, or
         governmental authorization (nor, to SFG's knowledge, do any grounds for
         any of the foregoing exist).

         (j) No Brokers. No action has been taken by SFG that would give rise to
     any valid claim against any party hereto for a brokerage commission,
     finder's fee or other like payment with respect to the transactions
     contemplated by this Agreement.

         (k) Takeover Laws. SFG has taken all action required to be taken by it
     in order to exempt this Agreement, the Stock Option Agreement and the
     transactions contemplated hereby and thereby from, and this Agreement, the
     Stock Option Agreement and the transactions contemplated hereby and thereby
     are exempt from, the requirements of any Takeover Laws applicable to SFG.

         (l) Environmental Matters. To SFG's knowledge, neither the conduct nor
     operation of SFG or its Subsidiaries nor any condition of any property
     presently or previously owned, 



                                       28
<PAGE>   32

     leased or operated by any of them (including, without limitation, in a
     fiduciary or agency capacity), or on which any of them holds a Lien,
     violated Environmental Laws and to SFG's knowledge no condition has existed
     or event has occurred with respect to any of them or any such property
     that, with notice or the passage of time, or both, is reasonably likely to
     result in liability under Environmental Laws. To SFG's knowledge, neither
     SFG nor any of its Subsidiaries has received any notice from any person or
     entity that SFG or its Subsidiaries or the operation or condition of any
     property ever owned, leased, operated, or held as collateral or in a
     fiduciary capacity by any of them are or were in violation of or otherwise
     are alleged to have liability under any Environmental Law, including, but
     not limited to, responsibility (or potential responsibility) for the
     cleanup or other remediation of any pollutants, contaminants, or hazardous
     or toxic wastes, substances or materials at, on, beneath, or originating
     from any such property.

         (m) Tax Matters. (i) All Tax Returns that are required to be filed by
     or with respect to SFG and its Subsidiaries have been duly filed, (ii) all
     Taxes shown to be due on the Tax Returns referred to in clause (i) have
     been paid in full, (iii) the Tax Returns referred to in clause (i) have
     been examined by the Internal Revenue Service or the appropriate state,
     local or foreign taxing authority or the period for assessment of the Taxes
     in respect of which such Tax Returns were required to be filed has expired,
     (iv) all deficiencies asserted or assessments made as a result of such
     examinations have been paid in full, (v) no issues that have been raised by
     the relevant taxing authority in connection with the examination of any of
     the Tax Returns referred to in clause (i) are currently pending, and (vi)
     no waivers of statutes of limitation have been given by or requested with
     respect to any Taxes of SFG or its Subsidiaries. Neither SFG nor any of its
     Subsidiaries has any liability with respect to income, franchise or similar
     Taxes that accrued on or before the end of the most recent period covered
     by the SFG SEC Documents filed prior to the date hereof in excess of the
     amounts accrued with respect thereto that are reflected in the financial
     statements included in SFG's SEC Documents filed on or prior to the date
     hereof. As of the date hereof, SFG has no reason to believe that any
     conditions exist that might prevent or impede the Parent Merger from
     qualifying as a reorganization with the meaning of Section 368(a) of the
     Code.

         (n) Books and Records. The books and records of SFG and its
     Subsidiaries have been fully, properly and accurately maintained in all
     material respects, and there are no material inaccuracies or discrepancies
     of any kind contained or reflected therein, and they fairly present the
     substance of events and transactions included therein.

         (o) Insurance. SFG's Disclosure Schedule sets forth all of the
     insurance policies, binders, or bonds maintained by SFG or its
     Subsidiaries. SFG and its Subsidiaries are insured with reputable insurers
     against such risks and in such amounts as the management of SFG reasonably
     has determined to be prudent in accordance with industry practices. All
     such insurance policies are in full force and effect; SFG and its
     Subsidiaries are not in material default thereunder; and all claims
     thereunder have been filed in due and timely fashion.


                                       29
<PAGE>   33

         (p) Accounting Treatment. As of the date hereof, after due inquiry, SFG
is aware of no reason why the Merger will fail to qualify for "pooling-of-
interests" accounting treatment.

         (q) Contracts. Neither SFG nor any of its Subsidiaries is in default
     under any contract, agreement, commitment, arrangement, lease, insurance
     policy or other instrument to which it is a party, by which its respective
     assets, business, or operations may be bound or affected in any way, or
     under which it or its respective assets, business, or operations receive
     benefits, and there has not occurred any event that, with the lapse of time
     or the giving of notice or both, would constitute such a default.

         (r) Disclosure. The representations and warranties contained in this
     Section 5.04 do not contain any untrue statement of a material fact or omit
     to state any material fact necessary in order to make the statements and
     information contained in this Section 5.04 not misleading.

         (s) Risk Management Instruments. All material interest rate swaps,
     caps, floors, option agreements, futures and forward contracts and other
     similar risk management arrangements, whether entered into for SFG's own
     account, or for the account of one or more of its Subsidiaries or their
     customers, were entered into (i) in accordance with prudent business
     practices and all applicable laws, rules, regulations and regulatory
     policies and with counterparties believed to be financially responsible at
     the time; and each of them constitutes the valid and legally binding
     obligation of SFG or one of its Subsidiaries, enforceable in accordance
     with its terms (except as enforceability may be limited by applicable
     bankruptcy, insolvency, reorganization, moratorium, fraudulent transfer and
     similar laws of general applicability relating to or affecting creditors'
     rights or by general equity principles), and is in full force and effect.
     Neither SFG nor its Subsidiaries, nor to SFG's knowledge any other party
     thereto, is in breach of any of its obligations under any such agreement or
     arrangement in any material respect.

         (t) Year 2000. Neither SFG nor any of its Subsidiaries has received, or
     has reason to believe that it will receive, a rating of less than
     "satisfactory" on any Year 2000 Report of Examination of any Regulatory
     Authority. SFG has disclosed to WBI a complete and accurate copy of its
     plan, including an estimate of the anticipated associated costs, for
     addressing the issues set forth in the statements of the FFIEC dated May 5,
     1997, entitled "Year 2000 Project Management Awareness," and December 17,
     1997, entitled "Safety and Soundness Guidelines Concerning the Year 2000
     Business Risk," as such issues affect it and its Subsidiaries, and such
     plan is in material compliance with the schedule set forth in the FFIEC
     statements.

         6.01 REASONABLE BEST EFFORTS. Subject to the terms and conditions of
this Agreement, each of WBI and SFG agrees to use their reasonable best efforts
in good faith to take, or cause to be taken, all actions, and to do, or cause to
be done, all things necessary, proper or desirable, or advisable under
applicable laws, so as to permit consummation of the Merger as promptly as
practicable and otherwise to enable consummation of the transactions
contemplated hereby and shall cooperate fully with the other party hereto to
that end.

         6.02 STOCKHOLDER APPROVAL. WBI agrees to take, in accordance with
applicable law, the WBI Certificate and WBI By-Laws, all action necessary to

adopted by WBI's stockholders for consummation of the Parent Merger (including
any adjournment or postponement, the "WBI Meeting"), as promptly as practicable
after the Registration Statement is declared effective. The WBI Board shall
recommend that its stockholders adopt this Agreement at the WBI Meeting unless
otherwise necessary under the applicable fiduciary duties of the WBI Board, as
determined by the WBI Board in good faith after consultation with and based upon
advice of independent legal counsel.

         6.03 REGISTRATION STATEMENT. (a) SFG agrees to prepare pursuant to all
applicable laws, rules and regulations a registration statement on Form S-4 (the
"Registration Statement") to be filed by SFG with the SEC in connection with the
issuance of SFG Common Stock in the Parent Merger (including the proxy statement
and prospectus and other proxy solicitation materials of WBI constituting a part
thereof (the "Proxy Statement") and all related documents). WBI agrees to
cooperate, and to cause its Subsidiaries to cooperate, with SFG, its counsel and
its accountants, in preparation of the Registration Statement and the Proxy
Statement; and provided that WBI and its Subsidiaries have cooperated as
required above, SFG agrees to file the Proxy Statement and the Registration
Statement (together, the "Proxy/Prospectus") with the SEC as promptly as
reasonably practicable. Each of WBI and SFG agrees to use all reasonable efforts
to cause the Proxy/Prospectus to be declared effective under the Securities Act
as promptly as reasonably practicable after filing thereof. SFG also agrees to
use all reasonable efforts to obtain, prior to the effective date of the
Registration Statement, all necessary state securities law or "Blue Sky" permits
and approvals required to carry out the transactions contemplated by this
Agreement. WBI agrees to furnish to SFG all information concerning WBI, its
Subsidiaries, officers, directors and stockholders as may be reasonably
requested in connection with the foregoing.

         (b) Each of WBI and SFG agrees, as to itself and its Subsidiaries, that
     none of the information supplied or to be supplied by it for inclusion or
     incorporation by reference in (i) the Registration Statement will, at the
     time the Registration Statement and each amendment or supplement thereto,
     if any, becomes effective under the Securities Act, contain any untrue
     statement of a material fact or omit to state any material fact required to
     be stated therein or necessary to make the statements therein not
     misleading, and (ii) the Proxy Statement and any amendment or supplement
     thereto will, at the date of mailing to the WBI 





                                       31
<PAGE>   35

     stockholders and at the time of the WBI Meeting, as the case may be,
     contain any untrue statement of a material fact or omit to state any
     material fact required to be stated therein or necessary to make the
     statements therein not misleading or any statement which, in the light of
     the circumstances under which such statement is made, will be false or
     misleading with respect to any material fact, or which will omit to state
     any material fact necessary in order to make the statements therein not
     false or misleading or necessary to correct any statement in any earlier
     statement in the Proxy Statement or any amendment or supplement thereto.
     Each of WBI and SFG further agrees that if it shall become aware prior to
     the Effective Date of any information furnished by it that would cause any
     of the statements in the Proxy Statement to be false or misleading with
     respect to any material fact, or to omit to state any material fact
     necessary to make the statements therein not false or misleading, to
     promptly inform the other party thereof and to take the necessary steps to
     correct the Proxy Statement.

         (c) SFG agrees to advise WBI, promptly after SFG receives notice
     thereof, of the time when the Registration Statement has become effective
     or any supplement or amendment has been filed, of the issuance of any stop
     order or the suspension of the qualification of SFG Stock for offering or
     sale in any jurisdiction, of the initiation or threat of any proceeding for
     any such purpose, or of any request by the SEC for the amendment or
     supplement of the Registration Statement or for additional information.

         6.04 PRESS RELEASES. Each of WBI and SFG agrees that it will not,
without the prior approval of the other party, issue any press release or
written statement for general circulation relating to the transactions
contemplated hereby, except as otherwise required by applicable law or
regulation or NASDAQ rules.

         6.05 ACCESS; INFORMATION. (a) Each of WBI and SFG agrees that upon
reasonable notice and subject to applicable laws relating to the exchange of
information, it shall afford the other party and the other party's officers,
employees, counsel, accountants and other authorized representatives, such
access during normal business hours throughout the period prior to the Effective
Time to the books, records (including, without limitation, tax returns and work
papers of independent auditors), properties, personnel and to such other
information as any party may reasonably request and, during such period, it
shall furnish promptly to such other party (i) a copy of each material report,
schedule and other document filed by it pursuant to federal or state securities
or banking laws, and (ii) all other information concerning the business,
properties and personnel of it as the other may reasonably request.

         (b) Each agrees that it will not, and will cause its representatives
     not to, use any information obtained pursuant to this Section 6.05 (as well
     as any other information obtained prior to the date hereof in connection
     with the entering into of this Agreement) for any purpose unrelated to the
     consummation of the transactions contemplated by this Agreement. Subject to
     the requirements of law, each party will keep confidential, and will cause
     its representatives to keep confidential, all information and documents
     obtained pursuant to this Section 6.05 (as well as any other information
     obtained prior to the date hereof in connection 



                                       32
<PAGE>   36

     with the entering into of this Agreement) unless such information (i) was
     already known to such party, (ii) becomes available to such party from
     other sources not known by such party to be bound by a confidentiality
     obligation, (iii) is disclosed with the prior written approval of the party
     to which such information pertains or (iv) is or becomes readily
     ascertainable from published information or trade sources. In the event
     that this Agreement is terminated or the transactions contemplated by this
     Agreement shall otherwise fail to be consummated, each party shall promptly
     cause all copies of documents or extracts thereof containing information
     and data as to another party hereto to be returned to the party which
     furnished the same. No investigation by either party of the business and
     affairs of the other shall affect or be deemed to modify or waive any
     representation, warranty, covenant or agreement in this Agreement, or the
     conditions to either party's obligation to consummate the transactions
     contemplated by this Agreement.

         (c) During the period from the date of this Agreement to the Effective
     Time, WBI shall promptly furnish SFG with copies of all monthly and other
     interim financial statements produced in the ordinary course of business as
     the same shall become available.

         6.06 ACQUISITION PROPOSALS. WBI agrees that it shall not, and shall
cause its Subsidiaries and its and its Subsidiaries' officers, directors,
agents, advisors and affiliates not to, solicit or encourage inquiries or
proposals with respect to, or engage in any negotiations concerning, or provide
any confidential information to, or have any discussions with, any person
relating to, any Acquisition Proposal. It shall immediately cease and cause to
be terminated any activities, discussions or negotiations conducted prior to the
date of this Agreement with any parties other than SFG with respect to any of
the foregoing and shall use its reasonable best efforts to enforce any
confidentiality or similar agreement relating to an Acquisition Proposal. WBI
shall promptly (within 24 hours) advise SFG following the receipt by WBI of any
Acquisition Proposal and the substance thereof (including the identity of the
person making such Acquisition Proposal), and advise SFG of any material
developments with respect to such Acquisition Proposal immediately upon the
occurrence thereof. Notwithstanding the foregoing, but only after the receipt of
an Acquisition Proposal and during the period prior to the WBI Meeting, WBI may
provide information at the request of or enter into negotiations with the party
presenting the Acquisition Proposal with respect thereto, if the WBI Board
determines in good faith, after consultation with and based upon the advice of
independent legal counsel, that the failure to do so would result in a breach of
the fiduciary duties of the WBI Board to the WBI stockholders under applicable
law.

         6.07 AFFILIATE AGREEMENTS. Not later than the 15th day prior to the
mailing of the Proxy Statement, WBI shall deliver to SFG a schedule of each
person that, to the best of its knowledge, is or is reasonably likely to be, as
of the date of the WBI Meeting, deemed to be an "affiliate" of WBI (each, a "WBI
Affiliate") as that term is used in Rule 145 under the Securities Act or SEC
Accounting Series Releases 130 and 135. WBI shall use its reasonable best
efforts to cause each person who may be deemed to be a WBI Affiliate, as the
case may be, to execute and deliver to SFG on or before the date of mailing of
the Proxy Statement an agreement in the form attached hereto as Exhibit B.



                                       33
<PAGE>   37

         6.08 TAKEOVER LAWS. No party hereto shall take any action that would
cause the transactions contemplated by this Agreement or the Stock Option
Agreement to be subject to requirements imposed by any Takeover Law and each of
them shall take all necessary steps within its control to exempt (or ensure the
continued exemption of) the transactions contemplated by this Agreement from, or
if necessary challenge the validity or applicability of, any applicable Takeover
Law, as now or hereafter in effect.

         6.09 CERTAIN POLICIES. Prior to the Effective Date, WBI shall,
consistent with generally accepted accounting principles and on a basis mutually
satisfactory to it and SFG, modify and change its loan, litigation and real
estate valuation policies and practices (including loan classifications and
levels of reserves) so as to be applied on a basis that is consistent with that
of SFG; provided, however, that WBI shall not be obligated to take any such
action pursuant to this Section 6.09 unless and until SFG acknowledges that all
conditions to its obligation to consummate the Merger have been satisfied and
certifies to WBI that SFG's representations and warranties, subject to Section
5.02, are true and correct as of such date and that SFG is otherwise material in
compliance with this Agreement. WBI's representations, warranties and covenants
contained in this Agreement shall not be deemed to be untrue or breached in any
respect for any purpose as a consequence of any modifications or changes
undertaken solely on account of this Section 6.09.

         6.10 NASDAQ LISTING. SFG shall file a listing application, or a NASDAQ
Notification Form for Change in the Number of Shares Outstanding, as required by
NASDAQ, with respect to the shares of SFG Common Stock to be issued to the
holders of WBI Common Stock in the Merger.

         6.11 REGULATORY APPLICATIONS. (a) SFG and WBI and their respective
Subsidiaries shall cooperate and use their respective reasonable best efforts to
prepare all documentation, to timely effect all filings and to obtain all
permits, consents, approvals and authorizations of all third parties and
Governmental Authorities necessary to consummate the transactions contemplated
by this Agreement. Each of SFG and WBI shall have the right to review in
advance, and to the extent practicable each will consult with the other, in each
case subject to applicable laws relating to the exchange of information, with
respect to, and shall be provided in advance so as to reasonably exercise its
right to review in advance, all material written information submitted to any
third party or any Governmental Authority in connection with the transactions
contemplated by this Agreement. In exercising the foregoing right, each of the
parties hereto agrees to act reasonably and as promptly as practicable. Each
party hereto agrees that it will consult with the other party hereto with
respect to the obtaining of all material permits, consents, approvals and
authorizations of all third parties and Governmental Authorities necessary or
advisable to consummate the transactions contemplated by this Agreement and each
party will keep the other party apprised of the status of material matters
relating to completion of the transactions contemplated hereby.



                                       34
<PAGE>   38

         (b) Each party agrees, upon request, to furnish the other party with
     all information concerning itself, its Subsidiaries, directors, officers
     and stockholders and such other matters as may be reasonably necessary or
     advisable in connection with any filing, notice or application made by or
     on behalf of such other party or any of its Subsidiaries to any third party
     or Governmental Authority.

         6.12 INDEMNIFICATION. (a) Following the Effective Date and for a period
of six years thereafter, SFG shall indemnify, defend and hold harmless the
present directors, officers and employees of WBI and its Subsidiaries (each, an
"Indemnified Party") against all costs or expenses (including reasonable
attorneys' fees), judgments, fines, losses, claims, damages or liabilities
(collectively, "Costs") incurred in connection with any claim, action, suit,
proceeding or investigation, whether civil, criminal, administrative or
investigative, arising out of actions or omissions occurring at or prior to the
Effective Time (including, without limitation, the transactions contemplated by
this Agreement) to the fullest extent that WBI is permitted to indemnify (and
advance expenses to) its directors, officers, and employees under the laws of
the State of Delaware, the WBI Certificate and the WBI By-Laws as in effect on
the date hereof; provided that any determination required to be made with
respect to whether an officer's, director's or employee's conduct complies with
the standards set forth under Delaware law, the WBI Certificate and the WBI
By-Laws shall be made by independent counsel (which shall not be counsel that
provides material services to SFG) selected by SFG and reasonably acceptable to
such officer, director or employee.

         (b) For a period of three years from the Effective Time, SFG shall use
     its reasonable best efforts to provide that portion of director's and
     officer's liability insurance that serves to reimburse the present and
     former officers and directors of WBI or any of its Subsidiaries (determined
     as of the Effective Time) (as opposed to WBI) with respect to claims
     against such directors and officers arising from facts or events which
     occurred before the Effective Time, which insurance shall contain at least
     the same coverage and amounts, and contain terms and conditions no less
     advantageous, as that coverage currently provided by WBI; provided,
     however, that in no event shall SFG be required to extend more than 200
     percent of the current amount expended by WBI (the "Insurance Amount") to
     maintain or procure such directors and officers insurance coverage;
     provided , further that if SFG is unable to maintain or obtain the
     insurance called for by this Section 6.12(b), SFG shall use its reasonable
     best efforts to obtain as much comparable insurance or is available for the
     Insurance Amount; provided, further, that officers and directors of WBI or
     any Subsidiary may be required to make application and provide customary
     representations and warranties to SFG's insurance carrier for the purpose
     of obtaining such insurance.

         (c) Any Indemnified Party wishing to claim indemnification under
     Section 6.12(a), upon learning of any claim, action, suit, proceeding or
     investigation described above, shall promptly notify SFG thereof; provided
     that the failure so to notify shall not affect the obligations of SFG under
     Section 6.12(a) unless and to the extent that SFG is actually prejudiced as
     a result of such failure.


                                       35
<PAGE>   39

         (d) If SFG or any of its successors or assigns shall consolidate with
     or merge into any other entity and shall not be the continuing or surviving
     entity of such consolidation or merger or shall transfer all or
     substantially all of its assets to any entity, then and in each case,
     proper provision shall be made so that the successors and assigns of SFG
     shall assume the obligations set forth in this Section 6.12.

         6.13 BENEFIT PLANS. (a) Except as expressly contemplated by a separate
     agreement entered into by WBI and SFG on the date hereof, at the Effective
     Time, SFG or an applicable SFG Subsidiary, as the case may be, shall be
     substituted for WBI and each WBI Subsidiary as the sponsoring employer
     under those benefit and welfare plans with respect to which WBI or any of
     its Subsidiaries is a sponsoring employer immediately prior to the
     Effective Time, and shall assume and be vested with all of the powers,
     rights, duties, obligations and liabilities previously vested in WBI and/or
     its Subsidiaries with respect to each such plan. Except as expressly
     contemplated by a separate agreement entered into by WBI and SFG on the
     date hereof, each such plan shall be continued in effect by SFG or an
     applicable SFG Subsidiary after the Effective Time without a termination or
     discontinuance thereof as a result of the Merger, subject to the power
     reserved to SFG or any applicable SFG Subsidiary under each such plan to
     subsequently amend or terminate the plan, which amendments or terminations
     shall comply with the terms of the plans and applicable law. WBI, each WBI
     Subsidiary, and SFG will use all reasonable efforts (i) to effect said
     substitutions and assumptions, and such other actions contemplated under
     this Agreement, and (ii) to amend such plans as to the extent necessary to
     provide for said substitutions and assumptions, and such other actions
     contemplated under this Agreement.

         (b) At or as promptly as practicable after the Effective Time, SFG
     shall provide, or cause an appropriate SFG Subsidiary to provide, to each
     employee of WBI, and its wholly-owned subsidiaries as of the Effective Time
     ("WBI Employees") the opportunity to participate in, subject to eligibility
     and vesting provisions, each employee benefit and welfare plan maintained
     by SFG or an appropriate SFG Subsidiary, whichever is applicable, for
     similarly-situated employees; provided that with respect to such plans
     maintained by SFG or an SFG Subsidiary, whichever is applicable, WBI
     Employees shall be given full credit for their service with WBI and its
     Subsidiaries in determining participation in, eligibility for and vesting
     in benefits thereunder and past years of service will be fully taken into
     account for vacation and severance benefits to the extent applicable;
     provided further that WBI Employees shall not be subject to any
     pre-existing condition exclusions under the group health plan of SFG or any
     applicable SFG Subsidiary; and provided further that to the extent that the
     initial period of coverage for WBI Employees under any plan of SFG or an
     SFG Subsidiary, whichever is applicable, that is an "employee benefit plan"
     as defined in Section 3(1) of ERISA is not a full 12-month period of
     coverage, WBI Employees shall be given credit under the applicable welfare
     plan for any deductibles and co-insurance payments made by such WBI
     Employees under the corresponding welfare plan of WBI or an applicable WBI
     subsidiary during the balance of such 12-month period of coverage. Nothing
     in the preceding sentence shall 



                                       36
<PAGE>   40

     obligate SFG or any SFG Subsidiary to provide or cause to be provided any
     benefits duplicative to those provided under any benefit or welfare plan of
     WBI or any applicable WBI Subsidiary while continued pursuant to
     subparagraph (a) above. Except as otherwise provided in this Agreement, or
     in any applicable plan, the power of SFG or any SFG Subsidiary to amend or
     terminate any benefit or welfare plans of WBI and its Subsidiaries shall
     not be altered or affected. Moreover, this subsection 6.13(b) shall not
     confer upon any WBI Employee any rights or remedies hereunder and shall not
     constitute a contract of employment or create any rights, to be retained or
     otherwise, in employment at SFG or any SFG Subsidiary.

<PAGE>   41




              (c) Any separate agreement entered into by WBI and SFG on the date
hereof relating to employee or director benefits is incorporated herein by
reference and shall be deemed a part of this Agreement.

         6.14 NOTIFICATION OF CERTAIN MATTERS. Each of WBI and SFG shall give
prompt notice to the other of any fact, event or circumstance known to it that
(i) is reasonably likely, individually or taken together with all other facts,
events and circumstances known to it, to result in any Material Adverse Effect
with respect to it or (ii) would cause or constitute a material breach of any of
its representations, warranties, covenants or agreements contained herein.

         6.15 DIVIDEND COORDINATION. It is agreed by the parties hereto that
they will cooperate to assure that as a result of the Merger, during any
applicable period, there shall not be a duplicating payment of both an SFG and a
WBI dividend. The parties further agree that if the Effective Date is at the end
of a fiscal quarter, then they will cooperate to assure that the WBI
shareholders receive the dividend, if any, declared by WBI rather than the
dividend for that period, if any, by SFG. In no event will the selection of the
Effective Date cause the stockholders of WBI to lose a quarterly or a portion of
a quarterly dividend.

         6.16 BOARD REPRESENTATION. SFG shall cause its Executive Committee to
nominate for election to the SFG Board one (1) member of the WBI Board, which
nominee shall be recommended by WBI and reasonably satisfactory to SFG. At the
Effective Time, the nominee so selected shall be elected to fill a vacancy for a
term ending at the annual meeting of stockholders of SFG in 2001 and shall
thereafter serve as a member of the SFG Board until his successor is elected and
shall have qualified. SFG shall cause its Executive Committee to nominate for
election to the MAB Board one (1) member of the FFB Board, which nominee shall
be recommended by WBI and reasonably satisfactory to SFG.

         6.17 SEPARATE DIVISION OF MAB. In connection with the merger of FFB
into MAB, MAB shall name a new Community Bank Division, which will include all
of FFB's offices (with the exception of the Rossford, Ohio branch) in addition
to the MAB branches in Bowling Green, Elmore, North Baltimore, Grand Rapids,
Genoa, Stony Ridge, Weston and Bradner, Ohio.

         7.01 CONDITIONS TO EACH PARTY'S OBLIGATION TO EFFECT THE MERGER. The
respective obligation of each of SFG and WBI to consummate the Merger is subject
to the fulfillment or written waiver by SFG and WBI prior to the Effective Time
of each of the following conditions:

         (a) WBI Stockholder Approval. This Agreement shall have been duly
     adopted by the requisite vote of the stockholders of WBI.

         (b) Regulatory Approvals. All regulatory approvals required to
     consummate the transactions contemplated hereby shall have been obtained
     and shall remain in full force and effect and all statutory waiting periods
     in respect thereof shall have expired and no such approvals shall contain
     (i) any conditions, restrictions or requirements which the SFG Board
     reasonably determines would either before or after the Effective Time have
     a Material Adverse Effect on SFG after giving effect to the consummation of
     the Merger, or (ii) any conditions, restrictions or requirements that are
     not customary and usual for approvals of such type and which the SFG Board
     reasonably determines would either before or after the Effective Date be
     unduly burdensome.

         (c) No Injunction. No Governmental Authority of competent jurisdiction
     shall have enacted, issued, promulgated, enforced or entered any statute,
     rule, regulation, judgment, decree, injunction or other order (whether
     temporary, preliminary or permanent) which is in effect and prohibits
     consummation of the transactions contemplated by this Agreement.

         (d) Registration Statement. The Registration Statement shall have
     become effective under the Securities Act and no stop order suspending the
     effectiveness of the Registration Statement shall have been issued and no
     proceedings for that purpose shall have been initiated or threatened by the
     SEC.

         (e) Blue Sky Approvals. All permits and other authorizations under
     state securities laws necessary to consummate the transactions contemplated
     hereby and to issue the shares of SFG Common Stock to be issued in the
     Parent Merger shall have been received and be in full force and effect.

         (f) Accounting Treatment. SFG shall have received from Crowe, Chizek
     and Company, LLP, SFG's independent auditors, a letter, dated the date of
     or shortly prior to each of the mailing date of the Proxy Statement and the
     Effective Date, stating its opinion that the Merger shall qualify for
     pooling-of-interests accounting treatment.

         7.02 CONDITIONS TO OBLIGATION OF WBI. The obligation of WBI to
consummate the Merger is also subject to the fulfillment or written waiver by
WBI prior to the Effective Time of each of the following conditions:

         (a) Representations and Warranties. The representations and warranties
     of SFG set forth in this Agreement shall be true and correct, subject to
     Section 5.02, as of the date of this Agreement and as of the Effective Date
     as though made on and as of the Effective Date (except that representations
     and warranties that by their terms speak as of the date of this Agreement
     or some other date shall be true and correct as of such date), and WBI
     shall have received a certificate, dated the Effective Date, signed on
     behalf of SFG by the Chief 



                                       39
<PAGE>   43

     Executive Officer and the Chief Financial Officer of SFG to such effect.

         (b) Performance of Obligations of SFG. SFG shall have performed in all
     material respects all obligations required to be performed by them under

     by the Chief Executive Officer and the Chief Financial Officer of SFG to
     such effect.

         (c) Tax Opinion. WBI shall have received an opinion of counsel to SFG
     or SFG's independent auditors, dated the Effective Date, to the effect
     that, on the basis of facts, representations and assumptions set forth in
     such opinion, (i) the Parent Merger constitutes a "reorganization" within
     the meaning of Section 368 of the Code and (ii) no gain or loss will be
     recognized by stockholders of WBI who receive shares of SFG Common Stock in
     exchange for shares of WBI Common Stock, and cash in lieu of fractional
     share interests, other than the gain or loss to be recognized as to cash
     received in lieu of fractional share interests. In rendering its opinion,
     counsel to SFG or SFG's independent auditors, as the case may be, may
     require and rely upon representations contained in letters from WBI and 
     SFG.
     
         (d) Opinion of SFG's Counsel. WBI shall have received an opinion of
     counsel to SFG, dated the Effective Date, to the effect that, on the basis
     of the facts, representations and assumptions set forth in the opinion, (i)
     SFG is a corporation duly organized and in good standing under the laws of
     the State of Ohio, (ii) this Agreement has been duly executed by SFG and
     constitutes the binding obligation of SFG, enforceable against SFG in

     non-assessable, and (iv) that upon the filing of the certificate of merger
     with the DSS, the Parent Merger shall become effective.

         (e) Fairness Opinion. WBI shall have received a fairness opinion from
     Stifel, Nicolaus & Company, Incorporated, financial advisor to WBI, dated
     as of a date reasonably proximate to the date of the Proxy Statement,

                                   TERMINATION

         8.01 TERMINATION. This Agreement may be terminated, and the Acquisition
may be abandoned:

         (a) Mutual Consent. At any time prior to the Effective Time, by the
     mutual consent of SFG and WBI, if the Board of Directors of each so
     determines by vote of a majority of the members of its entire Board.

         (b) Breach. At any time prior to the Effective Time, by SFG or WBI, if
     its Board of Directors so determines by vote of a majority of the members
     of its entire Board, in the event of either: (i) a breach by the other
     party of any representation or warranty contained herein (subject to the
     standard set forth in Section 5.02), which breach cannot be or has not been
     cured within 30 days after the giving of written notice to the breaching
     party of such breach; or (ii) a breach by the other party of any of the
     covenants or agreements contained herein, which breach cannot be or has not
     been cured within 30 days after the giving of written notice to the

                                       41
<PAGE>   45


         (c) Delay. At any time prior to the Effective Time, by SFG or WBI, if
     its Board of Directors so determines by vote of a majority of the members
     of its entire Board, in the event that the Parent Merger is not consummated
     by September 30, 1999, except to the extent that the failure of the Parent
     Merger then to be consummated arises out of or results from the knowing
     action or inaction of the party seeking to terminate pursuant to this
     Section 8.01(c).

         (d) No Approval. By WBI or SFG, if its Board of Directors so determines
     by a vote of a majority of the members of its entire Board, in the event
     (i) the approval of any Governmental Authority required for consummation of
     the Merger and the other transactions contemplated by this Agreement shall
     have been denied by final nonappealable action of such Governmental
     Authority or (ii) the WBI stockholders fail to adopt this Agreement at the
     WBI Meeting.

         (e) By WBI, if the Average NASDAQ Closing Price (as defined below) of
     SFG Common Stock is less than $24.25, subject to adjustment for events
     occurring under Section 3.05, provided however, that prior to WBI
     exercising any right of termination pursuant to this Section 8.01(e), SFG
     may, at its option, for a period of three (3) business days, offer to
     distribute to WBI stockholders, in connection with Section 3.01, an
     additional number of shares of SFG Common Stock to offset the amount by
     which the Average NASDAQ Closing Price is below $24.25 subject to
     adjustment for events occurring under Section 3.05. In the event that SFG
     offers the stockholders of WBI additional shares of SFG Common Stock in
     accordance herewith, the right of WBI to terminate this Agreement under
     this Section 8.01 (e) shall be null and void, and the Merger Consideration
     shall be adjusted in accordance herewith. For purposes of this Section 8.01
     (e), the Average NASDAQ Closing Price shall mean the arithmetic mean of the
     NASDAQ closing prices of SFG Common Stock for the ten (10) trading days
     immediately preceding the eighth (8th) trading day prior to the Effective
     Date.

         8.02 EFFECT OF TERMINATION AND ABANDONMENT, ENFORCEMENT OF AGREEMENT.
In the event of termination of this Agreement and the abandonment of the Merger
pursuant to this Article VIII, no party to this Agreement shall have any
liability or further obligation to any other party hereunder except (i) as set
forth in Section 9.01 and (ii) that termination will not relieve a breaching
party from liability for any willful breach of this Agreement giving rise to
such termination. Notwithstanding anything contained herein to the contrary, the
parties hereto agree that irreparable damage will occur in the event that a
party breaches any of its obligations, duties, covenants and agreements
contained herein. It is accordingly agreed that the parties shall be entitled to
an injunction or injunctions to prevent breaches or threatened breaches of this
Agreement and to enforce specifically the terms and provisions of this Agreement
in any court of the United States or any state having jurisdiction, this being
in addition to any other remedy to which they are entitled by law or in equity.

                                   ARTICLE IX

                             STOCK OPTION AGREEMENT

      STOCK OPTION AGREEMENT, dated as of December 16, 1998, between Sky
Financial Group, Inc., an Ohio corporation ("Grantee"), and Wood Bancorp, Inc.,
a Delaware corporation ("Issuer").

                              W I T N E S S E T H:

      WHEREAS, Grantee and Issuer are simultaneously entering into an Agreement
and Plan of Merger (the "Merger Agreement");

      WHEREAS, as an inducement to the willingness of Grantee to enter into the
Merger Agreement, Issuer has agreed to grant Grantee the Option (as hereinafter
defined); and

      WHEREAS, the Board of Directors of Issuer has approved the grant of the
Option and the Merger Agreement;

      NOW, THEREFORE, in consideration of the foregoing and the mutual covenants
and agreements set forth herein and in the Merger Agreement, the parties hereto
agree as follows:

      1. (a) Issuer hereby grants to Grantee an unconditional, irrevocable
option (the "Option") to purchase, subject to the terms hereof, up to an
aggregate of 560,926 fully paid and nonassessable shares of the common stock,
par value $.01 per share, of Issuer ("Common Stock") at a price per share equal
to $16.00; PROVIDED, HOWEVER, that in the event Issuer issues or agrees to issue
any shares of Common Stock (other than shares of Common Stock issued pursuant to
stock options granted pursuant to any employee and director benefit plans prior
to the date hereof) at a price less than such price per share (as adjusted
pursuant to subsection (b) of Section 5), such price shall be equal to such
lesser price (such price, as adjusted if applicable, the "Option Price");
PROVIDED, FURTHER, that in no event shall the number of shares for which this
Option is exercisable exceed 19.9% of the issued and outstanding shares of
Common Stock. The number of shares of Common Stock that may be received upon the
exercise of the Option and the Option Price are subject to adjustment as herein
set forth.

      (b) In the event that any additional shares of Common Stock are issued or
otherwise become outstanding after the date of this Agreement (other than
pursuant to this Agreement and other than pursuant to an event described in
Section 5(a) hereof), the number of shares of Common Stock subject to the Option
shall be increased so that, after such issuance, such number together with any
shares of Common Stock previously issued pursuant hereto, equals 19.9% of the
number of shares of Common Stock then issued and outstanding without giving
effect to any shares subject or issued pursuant to the Option. Nothing contained
in this Section l(b) or elsewhere in this Agreement shall be deemed to authorize
Issuer to issue shares in breach any provision of the Merger Agreement.

      2. (a) The Holder (as hereinafter defined) may exercise the Option, in
whole or part, if, but only if, both an Initial Triggering Event (as hereinafter
defined) and a Subsequent Triggering Event (as hereinafter defined) shall have
occurred prior to the occurrence of an Exercise 




<PAGE>   2

Termination Event (as hereinafter defined), PROVIDED that the Holder shall have
sent the written notice of such exercise (as provided in subsection (e) of this
Section 2) within six (6) months following such Subsequent Triggering Event (or
such later period as provided in Section 10). Each of the following shall be an
Exercise Termination Event: (i) the Effective Time of the Merger; (ii)
termination of the Merger Agreement in accordance with the provisions thereof if
such termination occurs prior to the occurrence of an Initial Triggering Event
except a termination by Grantee pursuant to Section 8.01(b) of the Merger
Agreement (but only if the breach giving rise to the termination was willful) 
(a "Listed Termination"); or (iii) the passage of eighteen (18) months (or such
longer period as provided in Section 10) after termination of the Merger
Agreement if such termination follows the occurrence of an Initial Triggering
Event or is a Listed Termination. The term "Holder" shall mean the holder or
holders of the Option. Notwithstanding anything to the contrary contained
herein, (i) the Option may not be exercised at any time when Grantee shall be in
material breach of any of its representations, warranties, covenants or
agreements contained in the Merger Agreement such that Issuer shall be entitled
to terminate the Merger Agreement pursuant to Section 8.01(b) thereof and (ii)
this Agreement shall automatically terminate upon the proper termination of the
Merger Agreement by Issuer pursuant to Section 8.01(b) thereof as a result of
the material breach by Grantee of its representations, warranties, covenants or
agreements contained in the Merger Agreement.

      (b) The term "Initial Triggering Event" shall mean any of the following
events or transactions occurring on or after the date hereof:

          (i) Issuer or its financial institution subsidiary (the "Issuer
      Subsidiary"), without having received Grantee's prior written consent,
      shall have entered into an agreement to engage in an Acquisition
      Transaction (as hereinafter defined) with any person (the term "person"
      for purposes of this Agreement having the meaning assigned thereto in
      Sections 3(a)(9) and 13(d)(3) of the Securities Exchange Act of 1934, as
      amended (the "1934 Act"), and the rules and regulations thereunder) other
      than Grantee or any of its Subsidiaries (each a "Grantee Subsidiary") or
      the Board of Directors of Issuer (the "Issuer Board") shall have
      recommended that the shareholders of Issuer approve or accept any
      Acquisition Transaction other than as contemplated by the Merger
      Agreement. For purposes of this Agreement, (a) "Acquisition Transaction"
      shall mean (x) a merger or consolidation, or any similar transaction,
      involving Issuer or the Issuer Subsidiary (other than mergers,
      consolidations or similar transactions involving solely Issuer and/or one
      or more wholly-owned Subsidiaries of the Issuer, PROVIDED, any such
      transaction is not entered into in violation of the terms of the Merger
      Agreement), (y) a purchase, lease or other acquisition of all or any
      substantial part of the assets or deposits of Issuer or the Issuer
      Subsidiary, or (z) a purchase or other acquisition (including by way of
      merger, consolidation, share exchange or otherwise) of securities
      representing 10% or more of the voting power of Issuer or the Issuer
      Subsidiary and (b) "Subsidiary" shall have the meaning set forth in Rule
      12b-2 under the 1934 Act;

          (ii) Any person other than the Grantee or any Grantee Subsidiary shall
      have acquired beneficial ownership or the right to acquire beneficial
      ownership of 10% or more of the 





                                       2
<PAGE>   3

      outstanding shares of Common Stock (the term "beneficial ownership" for
      purposes of this Agreement having the meaning assigned thereto in Section
      13(d) of the 1934 Act, and the rules and regulations thereunder);

          (iii) The shareholders of Issuer shall have voted and failed to adopt
      the Merger Agreement at a meeting which has been held for that purpose or
      any adjournment or postponement thereof, or such meeting shall not have
      been held in violation of the Merger Agreement or shall have been
      cancelled prior to termination of the Merger Agreement if, prior to such
      meeting (or if such meeting shall not have been held or shall have been
      cancelled, prior to such termination), it shall have been publicly
      announced that any person (other than Grantee or any of its Subsidiaries)
      shall have made, or disclosed an intention to make, a proposal to engage
      in an Acquisition Transaction;

          (iv) The Issuer Board shall have withdrawn or modified (or publicly
      announced its intention to withdraw or modify) in any manner adverse in
      any respect to Grantee its recommendation that the shareholders of Issuer
      approve the transactions contemplated by the Merger Agreement, or Issuer
      or the Issuer Subsidiary shall have authorized, recommended, proposed (or
      publicly announced its intention to authorize, recommend or propose) an
      agreement to engage in an Acquisition Transaction with any person other
      than Grantee or a Grantee Subsidiary;

          (v) Any person other than Grantee or any Grantee Subsidiary shall have
      made a proposal to Issuer or its shareholders to engage in an Acquisition
      Transaction and such proposal shall have been publicly announced;

          (vi) Any person other than Grantee or any Grantee Subsidiary shall
      have filed with the SEC a registration statement or tender offer materials
      with respect to a potential exchange or tender offer that would constitute
      an Acquisition Transaction (or filed a preliminary proxy statement with
      the Securities and Exchange Commission (the "SEC") with respect to a
      potential vote by its shareholders to approve the issuance of shares to be
      offered in such an exchange offer);

          (vii) Issuer shall have willfully breached any covenant or obligation
      contained in the Merger Agreement in anticipation of engaging in an
      Acquisition Transaction, and following such breach Grantee would be
      entitled to terminate the Merger Agreement (whether immediately or after
      the giving of notice or passage of time or both); or

          (viii) Any person other than Grantee or any Grantee Subsidiary shall
      have filed an application or notice with the Board of Governors of the
      Federal Reserve System (the "Federal Reserve Board") or other federal or
      state bank regulatory or antitrust authority, which application or notice
      has been accepted for processing, for approval to engage in an Acquisition
      Transaction.


                                       3
<PAGE>   4

      (c) The term "Subsequent Triggering Event" shall mean any of the following
events or transactions occurring after the date hereof:

          (i) The acquisition by any person (other than Grantee or any Grantee
      Subsidiary) of beneficial ownership of 25% or more of the then outstanding
      Common Stock; or

          (ii) The occurrence of the Initial Triggering Event described in
      clause (i) of subsection (b) of this Section 2, except that the percentage
      referred to in clause (z) of the second sentence thereof shall be 25%.

      (d) Issuer shall notify Grantee promptly in writing of the occurrence of
any Initial Triggering Event or Subsequent Triggering Event (together, a
"Triggering Event"), it being understood that the giving of such notice by
Issuer shall not be a condition to the right of the Holder to exercise the
Option.

      (e) In the event the Holder is entitled to and wishes to exercise the
Option (or any portion thereof), it shall send to Issuer a written notice (the
date of which being herein referred to as the "Notice Date") specifying (i) the
total number of shares it will purchase pursuant to such exercise and (ii) a
place and date not earlier than three business days nor later than 60 business
days from the Notice Date for the closing of such purchase (the "Closing Date");
PROVIDED, that if prior notification to or approval of the Federal Reserve Board
or any other regulatory or antitrust agency is required in connection with such
purchase, the Holder shall promptly file the required notice or application for
approval, shall promptly notify Issuer of such filing, and shall expeditiously
process the same and the period of time that otherwise would run pursuant to
this sentence shall run instead from the date on which any required notification
periods have expired or been terminated or such approvals have been obtained and
any requisite waiting period or periods shall have passed. Any exercise of the
Option shall be deemed to occur on the Notice Date relating thereto.

      (f) At the closing referred to in subsection (e) of this Section 2, the
Holder shall (i) pay to Issuer the aggregate purchase price for the shares of
Common Stock purchased pursuant to the exercise of the Option in immediately
available funds by wire transfer to a bank account designated by Issuer and (ii)
present and surrender this Agreement to Issuer at its principal executive
offices, PROVIDED that the failure or refusal of the Issuer to designate such a
bank account or accept surrender of this Agreement shall not preclude the Holder
from exercising the Option .

      (g) At such closing, simultaneously with the delivery of immediately
available funds as provided in subsection (f) of this Section 2, Issuer shall
deliver to the Holder a certificate or certificates representing the number of
shares of Common Stock purchased by the Holder and, if the Option should be
exercised in part only, a new Option evidencing the rights of the Holder thereof
to purchase the balance of the shares purchasable hereunder.

 



                                      4

      (h) Certificates for Common Stock delivered at a closing hereunder may be
endorsed with a restrictive legend that shall read substantially as follows:

            "The transfer of the shares represented by this certificate is
      subject to certain provisions of an agreement, dated as of December 16,
      1998, between the registered holder hereof and Issuer and to resale
      restrictions arising under the Securities Act of 1933, as amended. A copy
      of such agreement is on file at the principal office of Issuer and will be
      provided to the holder hereof without charge upon receipt by Issuer of a
      written request therefor."

It is understood and agreed that: (i) the reference to the resale restrictions
of the Securities Act of 1933, as amended (the "1933 Act") in the above legend
shall be removed by delivery of substitute certificate(s) without such reference
if the Holder shall have delivered to Issuer a copy of a letter from the staff
of the SEC, or an opinion of counsel, in form and substance reasonably
satisfactory to Issuer, to the effect that such legend is not required for
purposes of the 1933 Act; (ii) the reference to the provisions of this Agreement
in the above legend shall be removed by delivery of substitute certificate(s)
without such reference if the shares have been sold or transferred in compliance
with the provisions of this Agreement and under circumstances that do not
require the retention of such reference in the opinion of Counsel to the Holder;
and (iii) the legend shall be removed in its entirety if the conditions in the
preceding clauses (i) and (ii) are both satisfied. In addition, such
certificates shall bear any other legend as may be required by law.

      (i) Upon the giving by the Holder to Issuer of the written notice of
exercise of the Option provided for under subsection (e) of this Section 2 and
the tender of the applicable purchase price in immediately available funds, the
Holder shall be deemed to be the holder of record of the shares of Common Stock
issuable upon such exercise, notwithstanding that the stock transfer books of
Issuer shall then be closed or that certificates representing such shares of
Common Stock shall not then be actually delivered to the Holder. Issuer shall
pay all expenses, and any and all United States federal, state and local taxes
and other charges that may be payable in connection with the preparation, issue
and delivery of stock certificates under this Section 2 in the name of the
Holder or its assignee, transferee or designee.

      3. Issuer agrees: (i) that it shall at all times maintain, free from
preemptive rights, sufficient authorized but unissued or treasury shares of
Common Stock so that the Option may be exercised without additional
authorization of Common Stock after giving effect to all other options,
warrants, convertible securities and other rights to purchase Common Stock; (ii)
that it will not, by charter amendment or through reorganization, consolidation,
merger, dissolution or sale of assets, or by any other voluntary act, avoid or
seek to avoid the observance or performance of any of the covenants,
stipulations or conditions to be observed or performed hereunder by Issuer;
(iii) promptly to take all action as may from time to time be required
(including (x) complying with all applicable premerger notification, reporting
and waiting period requirements specified in 15 U.S.C. Section 18a and
regulations promulgated thereunder and (y) in the event, under the Bank Holding
Company Act of 1956, as amended (the "BHCA"), or the Change in Bank Control Act
of 1978, as amended, or any state or other federal banking law, prior approval
of or notice to the 



                                       5
<PAGE>   6

Federal Reserve Board or to any state or other federal regulatory authority is
necessary before the Option may be exercised, cooperating fully with the Holder
in preparing such applications or notices and providing such information to the
Federal Reserve Board or such state or other federal regulatory authority as
they may require) in order to permit the Holder to exercise the Option and
Issuer duly and effectively to issue shares of Common Stock pursuant hereto; and
(iv) promptly to take all action provided herein to protect the rights of the
Holder against dilution.

      4. This Agreement (and the Option granted hereby) are exchangeable,
without expense, at the option of the Holder, upon presentation and surrender of
this Agreement at the principal office of Issuer, for other Agreements providing
for Options of different denominations entitling the holder thereof to purchase,
on the same terms and subject to the same conditions as are set forth herein, in
the aggregate the same number of shares of Common Stock purchasable hereunder.
The terms "Agreement" and "Option" as used herein include any Agreements and
related Options for which this Agreement (and the Option granted hereby) may be
exchanged. Upon receipt by Issuer of evidence reasonably satisfactory to it of
the loss, theft, destruction or mutilation of this Agreement, and (in the case
of loss, theft or destruction) of reasonably satisfactory indemnification, and
upon surrender and cancellation of this Agreement, if mutilated, Issuer will
execute and deliver a new Agreement of like tenor and date. Any such new
Agreement executed and delivered shall constitute an additional contractual
obligation on the part of Issuer, whether or not the Agreement so lost, stolen,
destroyed or mutilated shall at any time be enforceable by anyone.

      5. In addition to the adjustment in the number of shares of Common Stock
that are purchasable upon exercise of the Option pursuant to Section 1 of this
Agreement, the number of shares of Common Stock purchasable upon the exercise of
the Option and the Option Price shall be subject to adjustment from time to time
as provided in this Section 5.

      (a) In the event of any change in, or distributions in respect of, the
Common Stock by reason of stock dividends, split-ups, mergers,
recapitalizations, combinations, subdivisions, conversions, exchanges of shares
or the like, the type and number of shares of Common Stock purchasable upon
exercise hereof shall be appropriately adjusted and proper provision shall be
made so that, in the event that any additional shares of Common Stock are to be
issued or otherwise become outstanding as a result of any such change (other
than pursuant to an exercise of the Option), the number of shares of Common
Stock that remain subject to the Option shall be increased so that, after such
issuance and together with shares of Common Stock previously issued pursuant to
the exercise of the Option (as adjusted on account of any of the foregoing
changes in the Common Stock), it equals 19.9% of the number of shares of Common
Stock then issued and outstanding.

      (b) Whenever the number of shares of Common Stock purchasable upon
exercise hereof is adjusted as provided in this Section 5, the Option Price
shall be adjusted by multiplying the Option Price by a fraction, the numerator
of which shall be equal to the number of shares of 




                                       6
<PAGE>   7

Common Stock purchasable prior to the adjustment and the denominator of which
shall be equal to the number of shares of Common Stock purchasable after the
adjustment.

      6. Upon the occurrence of a Subsequent Triggering Event that occurs prior
to an Exercise Termination Event, Issuer shall, at the request of Grantee
delivered within twelve (12) months (or such later period as provided in Section
10) of such Subsequent Triggering Event (whether on its own behalf or on behalf
of any subsequent holder of this Option (or part thereof) or any of the shares
of Common Stock issued pursuant hereto), promptly prepare, file and keep current
a registration statement under the 1933 Act covering any shares issued and
issuable pursuant to this Option and shall use its reasonable best efforts to
cause such registration statement to become effective and remain current in
order to permit the sale or other disposition of any shares of Common Stock
issued upon total or partial exercise of this Option ("Option Shares") in
accordance with any plan of disposition requested by Grantee. Issuer will use
its reasonable best efforts to cause such registration statement promptly to
become effective and then to remain effective for such period not in excess of
180 days from the day such registration statement first becomes effective or
such shorter time as may be reasonably necessary to effect such sales or other
dispositions. Grantee shall have the right to demand two such registrations. The
Issuer shall bear the costs of such registrations (including, but not limited
to, Issuer's attorneys' fees, printing costs and filing fees, except for
underwriting discounts or commissions, brokers' fees and the fees and
disbursements of Grantee's counsel related thereto). The foregoing
notwithstanding, if, at the time of any request by Grantee for registration of
Option Shares as provided above, Issuer is in registration with respect to an
underwritten public offering by Issuer of shares of Common Stock, and if in the
good faith judgment of the managing underwriter or managing underwriters, or, if
none, the sole underwriter or underwriters, of such offering the offer and sale
of the Option Shares would interfere with the successful marketing of the shares
of Common Stock offered by Issuer, the number of Option Shares otherwise to be
covered in the registration statement contemplated hereby may be reduced;
PROVIDED, HOWEVER, that after any such required reduction the number of Option
Shares to be included in such offering for the account of the Holder shall
constitute at least 25% of the total number of shares to be sold by the Holder
and Issuer in the aggregate; and PROVIDED FURTHER, HOWEVER, that if such
reduction occurs, then Issuer shall file a registration statement for the
balance as promptly as practicable thereafter as to which no reduction pursuant
to this Section 6 shall be permitted or occur and the Holder shall thereafter be
entitled to one additional registration and the twelve (12) month period
referred to in the first sentence of this section shall be increased to
twenty-four (24) months. Each such Holder shall provide all information
reasonably requested by Issuer for inclusion in any registration statement to be
filed hereunder. If requested by any such Holder in connection with such
registration, Issuer shall become a party to any underwriting agreement relating
to the sale of such shares, but only to the extent of obligating itself in
respect of representations, warranties, indemnities and other agreements
customarily included in such underwriting agreements for Issuer. Upon receiving
any request under this Section 6 from any Holder, Issuer agrees to send a copy
thereof to any other person known to Issuer to be entitled to registration
rights under this Section 6, in each case by promptly mailing the same, postage
prepaid, to the address of record of the persons entitled to receive such
copies. Notwithstanding anything to the contrary contained herein, in no event
shall 




                                       7
<PAGE>   8

the number of registrations that Issuer is obligated to effect be increased by
reason of the fact that there shall be more than one Holder as a result of any
assignment or division of this Agreement.

      7. (a) At any time after the occurrence of a Repurchase Event (as defined
below) (i) at the request of the Holder, delivered prior to an Exercise
Termination Event (or such later period as provided in Section 10), Issuer (or
any successor thereto) shall repurchase the Option from the Holder at a price
(the "Option Repurchase Price") equal to the amount by which (A) the
market/offer price (as defined below) exceeds (B) the Option Price, multiplied
by the number of shares for which this Option may then be exercised and (ii) at
the request of the owner of Option Shares from time to time (the "Owner"),
delivered prior to an Exercise Termination Event (or such later period as
provided in Section 10), Issuer (or any successor thereto) shall repurchase such
number of the Option Shares from the Owner as the Owner shall designate at a
price (the "Option Share Repurchase Price") equal to the market/offer price
multiplied by the number of Option Shares so designated. The term "market/offer
price" shall mean the highest of (i) the price per share of Common Stock at
which a tender or exchange offer therefor has been made, (ii) the price per
share of Common Stock to be paid by any third party pursuant to an agreement
with Issuer, (iii) the highest closing price for shares of Common Stock within
the six-month period immediately preceding the date the Holder gives notice of
the required repurchase of this Option or the Owner gives notice of the required
repurchase of Option Shares, as the case may be, or (iv) in the event of a sale
of all or any substantial part of Issuer's assets or deposits, the sum of the
net price paid in such sale for such assets or deposits and the current market
value of the remaining net assets of Issuer as determined by a nationally
recognized investment banking firm selected by the Holder or the Owner, as the
case may be, and reasonably acceptable to Issuer, divided by the number of
shares of Common Stock of Issuer outstanding at the time of such sale. In
determining the market/offer price, the value of consideration other than cash
shall be determined by a nationally recognized investment banking firm selected
by the Holder or Owner, as the case may be, and reasonably acceptable to Issuer.

      (b) The Holder and the Owner, as the case may be, may exercise its right
to require Issuer to repurchase the Option and any Option Shares pursuant to
this Section 7 by surrendering for such purpose to Issuer, at its principal
office, a copy of this Agreement or certificates for Option Shares, as
applicable, accompanied by a written notice or notices stating that the Holder
or the Owner, as the case may be, elects to require Issuer to repurchase this
Option and/or the Option Shares in accordance with the provisions of this
Section 7. As promptly as practicable, and in any event within five business
days after the surrender of the Option and/or certificates representing Option
Shares and the receipt of such notice or notices relating thereto, Issuer shall
deliver or cause to be delivered to the Holder the Option Repurchase Price
and/or to the Owner the Option Share Repurchase Price therefor or the portion
thereof that Issuer is not then prohibited under applicable law and regulation
from so delivering.

      (c) To the extent that Issuer is prohibited under applicable law or
regulation, or as a consequence of administrative policy, from repurchasing the
Option and/or the Option Shares in full, Issuer shall immediately so notify the
Holder and/or the Owner and thereafter deliver or 



                                       8
<PAGE>   9

cause to be delivered, from time to time, to the Holder and/or the Owner, as
appropriate, the portion of the Option Repurchase Price and the Option Share
Repurchase Price, respectively, that it is no longer prohibited from delivering,
within five business days after the date on which Issuer is no longer so
prohibited; PROVIDED, HOWEVER, that if Issuer at any time after delivery of a
notice of repurchase pursuant to paragraph (b) of this Section 7 is prohibited
under applicable law or regulation, or as a consequence of administrative
policy, from delivering to the Holder and/or the Owner, as appropriate, the
Option Repurchase Price and the Option Share Repurchase Price, respectively, in
full (and Issuer hereby undertakes to use its reasonable best efforts to obtain
all required regulatory and legal approvals and to file any required notices as
promptly as practicable in order to accomplish such repurchase), the Holder or
Owner may revoke its notice of repurchase of the Option and/or the Option Shares
whether in whole or to the extent of the prohibition, whereupon, in the latter
case, Issuer shall promptly (i) deliver to the Holder and/or the Owner, as
appropriate, that portion of the Option Repurchase Price and/or the Option Share
Repurchase Price that Issuer is not prohibited from delivering; and (ii)
deliver, as appropriate, either (A) to the Holder, a new Agreement evidencing
the right of the Holder to purchase that number of shares of Common Stock
obtained by multiplying the number of shares of Common Stock for which the
surrendered Agreement was exercisable at the time of delivery of the notice of
repurchase by a fraction, the numerator of which is the Option Repurchase Price
less the portion thereof theretofore delivered to the Holder and the denominator
of which is the Option Repurchase Price, and/or (B) to the Owner, a certificate
for the Option Shares it is then so prohibited from repurchasing. If an Exercise
Termination Event shall have occurred prior to the date of the notice by Issuer
described in the first sentence of this subsection (c), or shall be scheduled to
occur at any time before the expiration of a period ending on the thirtieth day
after such date, the Holder shall nonetheless have the right to exercise the
Option until the expiration of such 30-day period.

      (d) For purposes of this Section 7, a "Repurchase Event" shall be deemed
to have occurred upon the occurrence of any of the following events or
transactions after the date hereof:

          (i) the acquisition by any person (other than Grantee or any Grantee
      Subsidiary) of beneficial ownership of 50% or more of the then outstanding
      Common Stock; or

          (ii) the consummation of any Acquisition Transaction described in
      Section 2(b)(i) hereof, except that the percentage referred to in clause
      (z) shall be 50%.

      8.  (a) In the event that prior to an Exercise Termination Event, Issuer
shall enter into an agreement (i) to consolidate with or merge into any person,
other than Grantee or a Grantee Subsidiary, or engage in a plan of exchange with
any person, other than Grantee or a Grantee Subsidiary and Issuer shall not be
the continuing or surviving corporation of such consolidation or merger or the
acquirer in such plan of exchange, (ii) to permit any person, other than Grantee
or a Grantee Subsidiary, to merge into Issuer or be acquired by Issuer in a plan
of exchange and Issuer shall be the continuing or surviving or acquiring
corporation, but, in connection with such merger or plan of exchange, the then
outstanding shares of Common Stock shall be changed into or 




                                       9
<PAGE>   10

exchanged for stock or other securities of any other person or cash or any other
property or the then outstanding shares of Common Stock shall after such merger
or plan of exchange represent less than 50% of the outstanding shares and share
equivalents of the merged or acquiring company, or (iii) to sell or otherwise
transfer all or a substantial part of its or the Issuer Subsidiary's assets or
deposits to any person, other than Grantee or a Grantee Subsidiary, then, and in
each such case, the agreement governing such transaction shall make proper
provision so that the Option shall, upon the consummation of any such
transaction and upon the terms and conditions set forth herein, be converted
into, or exchanged for, an option (the "Substitute Option"), at the election of
the Holder, of either (x) the Acquiring Corporation (as hereinafter defined) or
(y) any person that controls the Acquiring Corporation.

      (b) The following terms have the meanings indicated:

          (i) "Acquiring Corporation" shall mean (i) the continuing or
      surviving person of a consolidation or merger with Issuer (if other than
      Issuer), (ii) the acquiring person in a plan of exchange in which Issuer
      is acquired, (iii) the Issuer in a merger or plan of exchange in which
      Issuer is the continuing or surviving or acquiring person, and (iv) the
      transferee of all or a substantial part of Issuer's assets or deposits (or
      the assets or deposits of the Issuer Subsidiary).

          (ii) "Substitute Common Stock" shall mean the common stock issued by
      the issuer of the Substitute Option upon exercise of the Substitute
      Option.

          (iii) "Assigned Value" shall mean the market/offer price, as defined
      in Section 7.

          (iv) "Average Price" shall mean the average closing price of a share
      of the Substitute Common Stock for one year immediately preceding the
      consolidation, merger or sale in question, but in no event higher than the
      closing price of the shares of Substitute Common Stock on the day
      preceding such consolidation, merger or sale; PROVIDED that if Issuer is
      the issuer of the Substitute Option, the Average Price shall be computed
      with respect to a share of common stock issued by the person merging into
      Issuer or by any company which controls or is controlled by such person,
      as the Holder may elect.

      (c) The Substitute Option shall have the same terms as the Option,
PROVIDED that if the terms of the Substitute Option cannot, for legal reasons,
be the same as the Option, such terms shall be as similar as possible and in no
event less advantageous to the Holder. The issuer of the Substitute Option shall
also enter into an agreement with the then Holder or Holders of the Substitute
Option in substantially the same form as this Agreement (after giving effect for
such purpose to the provisions of Section 9), which agreement shall be
applicable to the Substitute Option.

      (d) The Substitute Option shall be exercisable for such number of shares
of Substitute Common Stock as is equal to the Assigned Value multiplied by the
number of shares of Common 




                                       10
<PAGE>   11

Stock for which the Option was exercisable immediately prior to the event
described in the first sentence of Section 8(a), divided by the Average Price.
The exercise price of the Substitute Option per share of Substitute Common Stock
shall then be equal to the Option Price multiplied by a fraction, the numerator
of which shall be the number of shares of Common Stock for which the Option was
exercisable immediately prior to the event described in the first sentence of
Section 8(a) and the denominator of which shall be the number of shares of
Substitute Common Stock for which the Substitute Option is exercisable.

      (e) In no event, pursuant to any of the foregoing paragraphs, shall the
Substitute Option be exercisable for more than 19.9% of the shares of Substitute
Common Stock outstanding prior to exercise of the Substitute Option. In the
event that the Substitute Option would be exercisable for more than 19.9% of the
shares of Substitute Common Stock outstanding prior to exercise but for this
clause (e), the issuer of the Substitute Option (the "Substitute Option Issuer")
shall make a cash payment to Holder equal to the excess of (i) the value of the
Substitute Option without giving effect to the limitation in this clause (e)
over (ii) the value of the Substitute Option after giving effect to the
limitation in this clause (e). This difference in value shall be determined by a
nationally recognized investment banking firm selected by the Holder.

      (f) Issuer shall not enter into any transaction described in subsection
(a) of this Section 8 unless the Acquiring Corporation and any person that
controls the Acquiring Corporation assume in writing all the obligations of
Issuer hereunder.

      9. (a) At the request of the holder of the Substitute Option (the
"Substitute Option Holder"), the issuer of the Substitute Option (the
"Substitute Option Issuer") shall repurchase the Substitute Option from the
Substitute Option Holder at a price (the "Substitute Option Repurchase Price")
equal to the amount by which (i) the Highest Closing Price (as hereinafter
defined) exceeds (ii) the exercise price of the Substitute Option, multiplied by
the number of shares of Substitute Common Stock for which the Substitute Option
may then be exercised, and at the request of the owner (the "Substitute Share
Owner") of shares of Substitute Common Stock (the "Substitute Shares"), the
Substitute Option Issuer shall repurchase the Substitute Shares at a price (the
"Substitute Share Repurchase Price") equal to the Highest Closing Price
multiplied by the number of Substitute Shares so designated. The term "Highest
Closing Price" shall mean the highest closing price for shares of Substitute
Common Stock within the six-month period immediately preceding the date the
Substitute Option Holder gives notice of the required repurchase of the
Substitute Option or the Substitute Share Owner gives notice of the required
repurchase of the Substitute Shares, as applicable.

      (b) The Substitute Option Holder and the Substitute Share Owner, as the
case may be, may exercise its respective rights to require the Substitute Option
Issuer to repurchase the Substitute Option and the Substitute Shares pursuant to
this Section 9 by surrendering for such purpose to the Substitute Option Issuer,
at its principal office, the agreement for such Substitute Option (or, in the
absence of such an agreement, a copy of this Agreement) and/or certificates for
Substitute Shares accompanied by a written notice or notices stating that the
Substitute Option Holder or the 




                                       11
<PAGE>   12

Substitute Share Owner, as the case may be, elects to require the Substitute
Option Issuer to repurchase the Substitute Option and/or the Substitute Shares
in accordance with the provisions of this Section 9. As promptly as practicable
and in any event within five business days after the surrender of the Substitute
Option and/or certificates representing Substitute Shares and the receipt of
such notice or notices relating thereto, the Substitute Option Issuer shall
deliver or cause to be delivered to the Substitute Option Holder the Substitute
Option Repurchase Price and/or to the Substitute Share Owner the Substitute
Share Repurchase Price therefor or the portion thereof which the Substitute
Option Issuer is not then prohibited under applicable law and regulation from so
delivering.

      (c) To the extent that the Substitute Option Issuer is prohibited under
applicable law or regulation, or as a consequence of administrative policy, from
repurchasing the Substitute Option and/or the Substitute Shares in part or in
full, the Substitute Option Issuer shall immediately so notify the Substitute
Option Holder and/or the Substitute Share Owner and thereafter deliver or cause
to be delivered, from time to time, to the Substitute Option Holder and/or the
Substitute Share Owner, as appropriate, the portion of the Substitute Option
Repurchase Price and/or the Substitute Share Repurchase Price, respectively,
which it is no longer prohibited from delivering, within five (5) business days
after the date on which the Substitute Option Issuer is no longer so prohibited;
PROVIDED, HOWEVER, that if the Substitute Option Issuer is at any time after
delivery of a notice of repurchase pursuant to subsection (b) of this Section 9
prohibited under applicable law or regulation, or as a consequence of
administrative policy, from delivering to the Substitute Option Holder and/or
the Substitute Share Owner, as appropriate, the Substitute Option Repurchase
Price and the Substitute Share Repurchase Price, respectively, in full (and the
Substitute Option Issuer shall use its reasonable best efforts to receive all
required regulatory and legal approvals as promptly as practicable in order to
accomplish such repurchase), the Substitute Option Holder and/or Substitute
Share Owner may revoke its notice of repurchase of the Substitute Option or the
Substitute Shares either in whole or to the extent of prohibition, whereupon, in
the latter case, the Substitute Option Issuer shall promptly (i) deliver to the
Substitute Option Holder or Substitute Share Owner, as appropriate, that portion
of the Substitute Option Repurchase Price or the Substitute Share Repurchase
Price that the Substitute Option Issuer is not prohibited from delivering; and
(ii) deliver, as appropriate, either (A) to the Substitute Option Holder, a new
Substitute Option evidencing the right of the Substitute Option Holder to
purchase that number of shares of the Substitute Common Stock obtained by
multiplying the number of shares of the Substitute Common Stock for which the
surrendered Substitute Option was exercisable at the time of delivery of the
notice of repurchase by a fraction, the numerator of which is the Substitute
Option Repurchase Price less the portion thereof theretofore delivered to the
Substitute Option Holder and the denominator of which is the Substitute Option
Repurchase Price, and/or (B) to the Substitute Share Owner, a certificate for
the Substitute Option Shares it is then so prohibited from repurchasing. If an
Exercise Termination Event shall have occurred prior to the date of the notice
by the Substitute Option Issuer described in the first sentence of this
subsection (c), or shall be scheduled to occur at any time before the expiration
of a period ending on the thirtieth day after such date, the Substitute 




                                       12
<PAGE>   13

Option Holder shall nevertheless have the right to exercise the Substitute
Option until the expiration of such 30-day period.

      10. The 30-day, 6-month, 12-month, 18-month or 24-month periods for
exercise of certain rights under Sections 2, 6, 7, 9, 12 and 14 shall be
extended: (i) to the extent necessary to obtain all regulatory approvals for the
exercise of such rights (for so long as the Holder, Owner, Substitute Option
Holder or Substitute Share Owner, as the case may be, is using commercially
reasonable efforts to obtain such regulatory approvals), and for the expiration
of all statutory waiting periods; and (ii) to the extent necessary to avoid
liability under Section 16(b) of the 1934 Act by reason of such exercise.

      11. Issuer hereby represents and warrants to Grantee as follows:

      (a) Issuer has full corporate power and authority to execute and deliver
this Agreement and to consummate the transactions contemplated hereby. The
execution and delivery of this Agreement and the consummation of the
transactions contemplated hereby have been duly and validly authorized by the
Issuer Board prior to the date hereof and no other corporate proceedings on the
part of Issuer are necessary to authorize this Agreement or to consummate the
transactions so contemplated. This Agreement has been duly and validly executed
and delivered by Issuer.

      (b) Issuer has taken all necessary corporate action to authorize and
reserve and to permit it to issue, and at all times from the date hereof through
the termination of this Agreement in accordance with its terms will have
reserved for issuance upon the exercise of the Option, that number of shares of
Common Stock equal to the maximum number of shares of Common Stock at any time
and from time to time issuable hereunder, and all such shares, upon issuance
pursuant thereto, will be duly authorized, validly issued, fully paid,
nonassessable, and will be delivered free and clear of all claims, liens,
encumbrance and security interests and not subject to any preemptive rights.

      12. Neither of the parties hereto may assign any of its rights or
obligations under this Agreement or the Option created hereunder to any other
person, without the express written consent of the other party, except that in
the event an Initial Triggering Event shall have occurred prior to an Exercise
Termination Event, Grantee, subject to the express provisions hereof, may assign
in whole or in part its rights and obligations hereunder; PROVIDED, HOWEVER,
that until the date 15 days following the date on which the Federal Reserve
Board has approved an application by Grantee to acquire the shares of Common
Stock subject to the Option, Grantee may not assign its rights under the Option
except in (i) a widely dispersed public distribution, (ii) a private placement
in which no one party acquires the right to purchase in excess of 2% of the
voting shares of Issuer, (iii) an assignment to a single party (E.G., a broker
or investment banker) for the purpose of conducting a widely dispersed public
distribution on Grantee's behalf or (iv) any other manner approved by the
Federal Reserve Board.

      13. Each of Grantee and Issuer will use its reasonable best efforts to
make all filings with, and to obtain consents of, all third parties and
governmental authorities necessary to the consummation of the transactions
contemplated by this Agreement, including, without limitation, applying to the
Federal Reserve Board under the BHCA for approval to acquire the shares issuable
hereunder, but Grantee shall not be obligated to apply to state banking
authorities for approval to acquire the shares of Common Stock issuable
hereunder until such time, if ever, as it deems appropriate to do so.

      14. (a) Grantee may, at any time following a Repurchase Event and prior to
the occurrence of an Exercise Termination Event (or such later period as
provided in Section 10), relinquish the Option (together with any Option Shares
issued to and then owned by Grantee) to Issuer in exchange for a cash fee equal
to the Surrender Price; PROVIDED, HOWEVER, that Grantee may not exercise its
rights pursuant to this Section 14 if Issuer has repurchased the Option (or any
portion thereof) or any Option Shares pursuant to Section 7. The "Surrender
Price" shall be equal to $2.8 million (i) plus, if applicable, Grantee's
purchase price with respect to any Option Shares and (ii) minus, if applicable,
the excess of (B) the net cash amounts, if any, received by Grantee pursuant to
the arms' length sale of Option Shares (or any other securities into which such
Option Shares were converted or exchanged) to any unaffiliated party, over (B)
Grantee's purchase price of such Option Shares.

      (b) Grantee may exercise its right to relinquish the Option and any Option
Shares pursuant to this Section 14 by surrendering to Issuer, at its principal
office, a copy of this Agreement together with certificates for Option Shares,
if any, accompanied by a written notice stating (i) that Grantee elects to
relinquish the Option and Option Shares, if any, in accordance with the
provisions of this Section 14 and (ii) the Surrender Price. The Surrender Price
shall be payable in immediately available funds on or before the second business
day following receipt of such notice by Issuer.

      (c) To the extent that Issuer is prohibited under applicable law or
regulation, or as a consequence of administrative policy, from paying the
Surrender Price to Grantee in full, Issuer shall immediately so notify Grantee
and thereafter deliver or cause to be delivered, from time to time, to Grantee,
the portion of the Surrender Price that it is no longer prohibited from paying,
within five business days after the date on which Issuer is no longer so
prohibited; PROVIDED, HOWEVER, that if Issuer at any time after delivery of a
notice of surrender pursuant to paragraph (b) of this Section 14 is prohibited
under applicable law or regulation, or as a consequence of administrative
policy, from paying to Grantee the Surrender Price in full, (i) Issuer shall (A)
use its reasonable best efforts to obtain all required regulatory and legal
approvals and to file any required notices as promptly as practicable in order
to make such payments, (B) within five days of the submission or receipt of any
documents relating to any such regulatory and legal approvals, provide Grantee
with copies of the same, and (c) keep Grantee advised of both the status of any
such request for regulatory and legal approvals, as well as any discussions with
any relevant regulatory or other third party reasonably related to the same and
(ii) Grantee may revoke such notice of surrender by delivery of a notice of
revocation to Issuer and, upon delivery of such 



                                       14
<PAGE>   15

notice of revocation, the Exercise Termination Date shall be extended to a date
six months from the date on which the Exercise Termination Date would have
occurred if not for the provisions of this Section 14(c) (during which period
Grantee may exercise any of its rights hereunder, including any and all rights
pursuant to this Section 14).

      15. The parties hereto acknowledge that damages would be an inadequate
remedy for a breach of this Agreement by either party hereto and that the
obligations of the parties hereto shall be enforceable by either party hereto
through injunctive or other equitable relief. In connection therewith both
parties waive the posting of any bond or similar requirement.

      16. If any term, provision, covenant or restriction contained in this
Agreement is held by a court or a federal or state regulatory agency of
competent jurisdiction to be invalid, void or unenforceable, the remainder of
the terms, provisions and covenants and restrictions contained in this Agreement
shall remain in full force and effect, and shall in no way be affected, impaired
or invalidated. If for any reason such court or regulatory agency determines
that the Holder is not permitted to acquire, or Issuer is not permitted to
repurchase pursuant to Section 7, the full number of shares of Common Stock
provided in Section l(a) hereof (as adjusted pursuant to Section l(b) or Section
5 hereof), it is the express intention of Issuer to allow the Holder to acquire
or to require Issuer to repurchase such lesser number of shares as may be
permissible, without any amendment or modification hereof.

      17. All notices, requests, claims, demands and other communications
hereunder shall be deemed to have been duly given when delivered in person, by
fax, telecopy, or by registered or certified mail (postage prepaid, return
receipt requested) at the respective addresses of the parties set forth in the
Merger Agreement.

      18. This Agreement shall be governed by and construed in accordance with
the laws of the State of Ohio, without regard to the conflict of law principles
thereof (except to the extent that mandatory provisions of Federal law or of the
VSCA are applicable).

      19. This Agreement may be executed in two or more counterparts, each of
which shall be deemed to be an original, but all of which shall constitute one
and the same agreement.

      20. Except as otherwise expressly provided herein, each of the parties
hereto shall bear and pay all costs and expenses incurred by it or on its behalf
in connection with the transactions contemplated hereunder, including fees and
expenses of its own financial consultants, investment bankers, accountants and
counsel.

      21. Except as otherwise expressly provided herein or in the Merger
Agreement, this Agreement contains the entire agreement between the parties with
respect to the transactions contemplated hereunder and supersedes all prior
arrangements or understandings with respect thereof, written or oral. The terms
and conditions of this Agreement shall inure to the benefit of and be binding
upon the parties hereto and their respective successors and permitted assignees.

             SKY FINANCIAL GROUP, INC. ANNOUNCES PLANS TO AFFILIATE
                     FIRST FEDERAL BANK, BOWLING GREEN, OHIO



         DECEMBER 17, 1998 (BOWLING GREEN; OHIO; NASDAQ: SKYF) Sky Financial
Group, Inc. today announced the execution of a definitive agreement with Wood
Bancorp, Inc. (NASDAQ: FFWD) and its affiliate First Federal Bank, Bowling
Green, Ohio. First Federal Bank is a federal savings bank with seven offices in
Bowling Green, Rossford, Woodville, Pemberville, Grand Rapids and North
Baltimore, Ohio, with $130 million in total deposits. It is anticipated that the
transaction will be completed by June 30, 1999, pending regulatory approvals and
the approval of Wood Bancorp's shareholders. Immediately following the
affiliation, First Federal will merge with the Mid American National Bank &
Trust Company, a Sky Financial affiliate.

         Under the terms of the agreement, Wood Bancorp shareholders will
receive .7315 shares of Sky Financial Group common stock for each share of Wood
Bancorp common stock. The transaction is valued at $59 million. The exchange of
shares will qualify as a tax-free exchange, and the transaction will be
accounted for as a pooling-of-interests. Wood Bancorp has issued an option in
favor of Sky Financial to purchase up to 19.9% of the outstanding shares of Wood
Bancorp, at an exercise price of $16.00 per share, which is exercisable upon the
occurrence of certain events.

         "This in-market merger represents an important addition to Mid Am
Bank's already strong presence in the Northwest Ohio market area," stated Marty
E. Adams, President and Chief Operating Officer of Sky Financial Group. "With a
pro forma Wood county market share of 38% coupled with operating efficiencies
this transaction should contribute to our previously announced earnings
objectives, and will further enhance our leadership position in this important
market."

         Richard L. Gordley, First Federal's President and CEO, said the
affiliation with Sky Financial Group will benefit First Federal's customers
employees, shareholders, and the communities in which the bank operates. "Sky
Financial and First Federal are both well known for their strong customer
service approach and commitment to their communities, and we are proud to form a
partnership that will continue this proud tradition. Mr. Gordley further
explained that " this merger will allow us to provide a broader range of
financial services to our customers, while still allowing our customers to work
with the people they know and trust. We will now be able to offer investment,
insurance, leasing and trust services, as well as a host of other products and
services to our customers."

         David R. Francisco, Chairman and CEO of Sky Financial Group, said that
"this transaction meets our conservative acquisition criteria, and does not
rely upon significant revenue growth to achieve our goals. We look forward to
First Federal participating with us in our future growth."

Federal Bank, who have become accustomed to high quality, personalized service
during First Federal Bank's 75 year history," stated Patrick A.
Kennedy, President and CEO of Mid American National Bank & Trust Company.

         Robert E. Spitler, Chairman of the Board of First Federal, is expected
