                       PROPOSAL I -- ELECTION OF DIRECTORS

     The Board of Directors consists of seven members.  The By-Laws provide that
the Board of Directors  is to be divided  into three  classes as nearly equal in
number as  possible.  The  members of each class are to be elected for a term of
three years and until their  successors are elected and qualified.  One class of
directors  is to be  elected  annually.  Directors  must  have  their  principal
domicile  in St.  Joseph  County,  Indiana,  must  have  had a loan  or  deposit
relationship  with MFB Financial  for a continuous  period of 12 months prior to
their nomination to the board, and non-employee  directors must have served as a
member of a civic or community  organization based in St. Joseph County, Indiana
for at least a  continuous  period of 12 months  during the five years  prior to
their nomination to the Board. The nominees for director this year are Marian K.
Torian and Reginald H. Wagle,  each of whom is a current director of the Holding
Company. If elected by the shareholders at the Annual Meeting, the terms of Mrs.
Torian and Mr. Wagle will expire in 2001.

     Unless  otherwise   directed,   each  proxy  executed  and  returned  by  a
shareholder  will be voted for the election of the nominees listed below. If any
person named as a nominee should be unable or unwilling to stand for election at
the time of the Annual  Meeting,  the proxy holders will nominate and vote for a
replacement  nominee  recommended  by the Board of Directors.  At this time, the
Board of Directors  knows of no reason why the nominees  listed below may not be
able to serve as directors if elected.

     The following table sets forth certain  information  regarding the nominees
for the position of director of the Holding  Company,  including  the number and
percent of shares of Common Stock  beneficially  owned by such persons as of the
Voting Record Date. Unless otherwise indicated, each nominee has sole investment
and/or  voting power with respect to the shares shown as  beneficially  owned by
him. No nominee for  director  is related to any other  nominee for  director or
executive officer of the Holding Company by blood,  marriage,  or adoption,  and
there are no  arrangements or  understandings  between any nominee and any other
person  pursuant to which such nominee was  selected.  The table also sets forth
the number of shares of Holding Company Common Stock  beneficially  owned by all
directors and executive officers of the Holding Company as a group.

last fiscal year of the Board of Directors of the Holding  Company held while he
served as director  and of meetings of  committees  which he served  during that
fiscal  year.  The  Board  of  Directors  of the  Holding  Company  has an Audit
Committee  and  a  Stock  Compensation  Committee.  All  committee  members  are
appointed by the Board of Directors.

     The Audit  Committee,  comprised of all members of the Board of  Directors,
recommends the appointment of the Holding Company's independent accountants, and
meets with them to outline the scope and review the  results of such audit.  The
Audit  Committee  held one meeting  during the fiscal year ended  September  30,
1997.

     The Stock Compensation  Committee administers the Option Plan and the RRPs.
The members of that  Committee are Mrs.  Torian and Messrs.  Eberhart,  Kintner,
Marien and Wagle. It held one meeting during the fiscal year ended September 30,
1997.

     The Board of Directors  nominated  the slate of directors  set forth in the
Proxy  Statement.  Although the Board of  Directors of the Holding  Company will
consider  nominees  recommended by shareholders,  it has not actively  solicited
recommendations for nominees from shareholders nor has it established procedures
for this  purpose.  Article  III,  Section 12 of the Holding  Company's  By-Laws
provides  that  shareholders  entitled to vote for the election of directors may
name  nominees  for  election  to the Board of  Directors  but there are certain
requirements  that must be  satisfied  in order to do so.  Among  other  things,
written notice of a proposed nomination must be received by the Secretary of the
Holding  Company not less than 120 days prior to the Annual  Meeting;  provided,
however,  that in the event that less than 130 days' notice or public disclosure
of the date of the  meeting is given or made to  shareholders  (which  notice or
public  disclosure  includes  the date of the Annual  Meeting  specified  in the
Holding  Company's  By-Laws if the Annual Meeting is held on such date),  notice
must be received not later than the close of business on the 10th day  following
the day on which  such  notice  of the date of the  meeting  was  mailed or such
public disclosure was made.

Management Remuneration and Related Transactions

     Remuneration of Named Executive Officer

     During the fiscal year ended September 30, 1997, no cash  compensation  was
paid directly by the Holding Company to any of its executive  officers.  Each of
such officers was compensated by MFB Financial.

     The  following  table sets forth  information  as to annual,  long-term and
other compensation for services in all capacities to the Holding Company and its
subsidiaries  for the last two  fiscal  years of the  person who served as chief
executive  officer of the Holding Company during the fiscal year ended September
30, 1997 (the "Named Executive Officer"). There were no other executive officers
of the Holding  Company who earned  over  $100,000 in salary and bonuses  during
that fiscal year.

Employment Contracts

     MFB  Financial has entered into a three-year  employment  contract with Mr.
Viater,  the Holding  Company's Named Executive  Officer.  The contract  extends
annually for an additional  one-year term to maintain its three-year term if the
Board of Directors of MFB  Financial  determines  to so extend it, unless notice
not to extend is properly  given by either  party to the  contract.  Mr.  Viater
receives  salary  under the  contract  equal to his  current  salary  subject to
increases approved by the Board of Directors.  The contract also provides, among
other  things,  for  participation  in other fringe  benefits and benefit  plans
available to MFB Financial's employees.  Mr. Viater may terminate his employment
upon sixty days' written  notice to MFB  Financial.  MFB Financial may discharge
him for cause (as  defined in the  contract)  at any time or in  certain  events
specified  by  OTS  regulations.   If  MFB  Financial  terminates  Mr.  Viater's
employment  for other than cause or if Mr. Viater  terminates his own employment
for cause (as defined in the  contract),  he will receive his base  compensation
under the contract for an additional  three years if the  termination  follows a
change of control of the Holding Company (as defined below). In addition, during
such period,  he will continue to participate in MFB Financial's group insurance
plans or receive comparable benefits.  Moreover, within a period of three months
after such termination  following a change of control,  Mr. Viater will have the
right to cause MFB Financial to purchase any stock options they hold for a price
equal to the fair market value (as defined in the contact) of the shares subject
to such options minus their option price.  Mr.  Viater's  employment  may not be
terminated by MFB Financial  without cause. If the payments  provided for in the
contract,  together with any other payments made to Mr. Viater by MFB Financial,
are deemed to be payments in  violation of the "golden  parachute"  rules of the
Code,  such payments will be reduced to the largest amount which would not cause
MFB Financial to lose a tax deduction for such payments under those rules. As of
the date hereof,  the cash compensation  which would be paid under the contracts
if the three-year payment obligation were triggered under the contracts would be
$417,924 to Mr. Viater.  For purposes of this employment  contract,  a change of
control of the Holding  Company is  generally  an  acquisition  of  control,  as
defined  in  regulations  issued  under the Change in Bank  Control  Act and the
Savings and Loan Holding Company Act.




     The  employment   contracts   provide  MFB  Financial   protection  of  its
confidential  business information and protection from competition by Mr. Viater
should he voluntarily terminate his employment without cause or be terminated by
MFB Financial for cause.  Similar  contracts have been entered into with respect
to three other executive officers of the Holding Company.

Compensation of Directors

     All directors of MFB Financial receive an annual fee of $4,000,  plus a fee
of $425 per Board meeting  attended.  Members of Board  Committees,  who are not
employees  of MFB  Financial,  are paid a separate  fee of $30 per  meeting.  As
Chairman  of the  Board  of  MFB  Financial,  Mrs.  Torian  receives  additional
directors' fees of $2,600 per year.

     Directors of the Holding  Company are not currently paid  directors'  fees.
The Holding  Company may, if it believes it is  necessary  to attract  qualified
directors  or otherwise  beneficial  to the Holding  Company,  adopt a policy of
paying directors' fees.

Transactions With Certain Related Persons

     MFB  Financial  has  followed a policy of  offering  to its  directors  and
executive  officers  real  estate  mortgage  loans  secured  by their  principal
residence  and  other  loans.  These  loans are made in the  ordinary  course of
business with the same collateral,  interest rates and underwriting  criteria as
those of comparable  transactions prevailing at the time and do not involve more
than the normal risk of collectibility or present other unfavorable features.

                        PROPOSAL II -- STOCK OPTION PLAN

     The Board of Directors of the Holding Company  adopted the MFB Corp.  Stock
Option Plan (the "Option  Plan") on August 19, 1997.  The essential  features of
the Option Plan are summarized  below,  but the Option Plan is set forth in full
in Exhibit A to this Proxy  Statement,  and all statements  made in this summary
are qualified by reference to the full text of the Option Plan.

Purpose

     The purpose of the Option Plan is to provide to certain directors, officers
and other key employees of the Holding Company and its  subsidiaries  (currently
approximately  ten persons) a favorable  opportunity  to acquire Common Stock of
the Holding  Company and thereby  increase the incentive of such persons to work
for the success of the Holding Company and its  subsidiaries and better enabling
such entities to attract or retain capable directors and executive personnel.

     The Option Plan  provides  for the grant of both  incentive  stock  options
(options that afford  favorable tax treatment to recipients upon compliance with
certain  restrictions  and that do not normally  result in tax deductions to the
Holding  Company)  and  options  that  do not so  qualify  (non-qualified  stock
options).

Administration

     The Option Plan is  administered,  construed and interpreted by a committee
consisting of at least two members of the Holding  Company's Board of Directors.
Currently,  the Holding Company's Stock Compensation  Committee  administers the
Option Plan. The Stock  Compensation  Committee  selects the individuals to whom
options or cash  awards will be granted and  determines  the time of grant,  the
number of shares of stock to be covered by each  option,  the amount of any cash
awards,  the option price,  the period within which the option may be exercised,
whether the option is an incentive stock option or  non-qualified  stock option,
and any other  terms and  conditions  of the  options  or cash  awards  granted.
Members of the Stock Compensation Committee must be nonemployee directors of the
Holding  Company.  The current members of that Committee are set forth on page 4
of this Proxy Statement.

Reservation of Shares




     The Holding  Company has  reserved  150,000  shares of its Common Stock for
issuance  upon exercise of options to be granted under the Option Plan. No stock
options have been granted under the Option Plan as yet.  Shares issued under the
Option Plan may be  authorized  but  unissued  shares or treasury  shares of the
Holding  Company.  In the  event of  corporate  changes  affecting  the  Holding
Company's  Common  Stock,  such  as  reorganizations,  recapitalizations,  stock
splits,   stock   dividends,   mergers,   consolidations,    liquidations,   and
extraordinary  distributions  (consisting of cash, securities, or other assets),
the Stock Compensation Committee may make appropriate  adjustments in the number
and kind of shares reserved under the Option Plan and in the option price under,
and the number and kind of shares covered by, outstanding  options granted under
the Option Plan.  Any shares subject to an option which expires or is terminated
before exercise will again be available for issuance under the Option Plan.

     Options and cash awards may be granted to  directors,  officers  (including
officers who are members of the Board of  Directors)  and other key employees of
the Holding Company and its subsidiaries who are materially  responsible for the
management  or  operation  of  the  business  of  the  Holding  Company  or  its
subsidiaries and have provided  valuable  services to the Holding Company or its
subsidiaries.
Such individuals may be granted more than one option under the Option Plan.

Terms of the Options

     Stock  Option  Price.  The price to be paid for shares of Common Stock upon
the  exercise of each  incentive  stock  option  shall not be less than the fair
market value of such shares on the date on which the option is granted. However,
the Committee does have the discretion to award  non-qualified  stock options to
eligible  employees and directors of the Holding Company or of its  subsidiaries
at a price no less than 85% of the fair market  value of the Common Stock on the
date the option is granted.  Incentive  stock options granted to holders of more
than 10% of the  combined  voting  power of all  classes of stock of the Holding
Company  may be granted at an option  price no less than 110% of the fair market
value of the stock on the date of grant.

     Option  Term.  No option may have a term  longer than ten years and one day
from the date  grant.  However,  under the  Internal  Revenue  Code of 1986,  as
amended (the  "Code"),  incentive  stock options may not have terms in excess of
ten years.  Incentive  stock options  granted to holders of more than 10% of the
combined  voting  power of all classes of stock of the  Holding  Company may not
have terms in excess of five years.

     Exercise of Option.  The option  price of each share of stock is to be paid
in full in cash at the time of exercise. Under certain circumstances, the Option
Plan  permits  optionees  to deliver a notice to their  broker to deliver to the
Holding Company the total option price in cash and the amount of any taxes to be
withheld from the optionee's  compensation  as a result of any  withholding  tax
obligation  of the  Holding  Company.  Payment of the  option  price may also be
effected by tendering whole shares of the Holding  Company's  Common Stock owned
by the Optionee  and cash having a fair market value equal to the cash  exercise
price of the shares with respect to which the option is being exercised. Options
may  be  exercisable  in  full  at  any  time  during  their  term  or  in  such
installments,  on a cumulative  basis, as the Stock  Compensation  Committee may
determine,  except that no option may be  exercised at any time as to fewer than
100 shares  unless the  exercise is with  respect to an entire  residue of fewer
than 100 shares,  and no option may be exercised  during the first six months of
its term.

     Exercise  of Options by Other than  Outside  Directors.  Except as provided
below, upon termination of an  optionholder's  employment by the Holding Company
and its  subsidiaries,  all rights under any options  granted to him but not yet
exercised terminate.  In the event that an optionee retires pursuant to any then
existing pension plan of the Holding Company or its subsidiaries, his option may
be exercised by him in whole or in part within three years after his  retirement
until the expiration of the option term fixed by the  Committee,  whether or not
the option was otherwise exercisable by him at his date of retirement; provided,
however,  that if he remains a director  or  director  emeritus  of the  Holding
Company he may exercise such option until the later of (a) three years after his
retirement  or (b) six  months  after he ceases  to be a  director  or  director
emeritus of the Holding  Company.  If an  optionee's  employment  by the Holding
Company  and its  subsidiaries  terminates  by  reason  of  permanent  and total
disability,  his option may be  exercised  by him in whole or in part within one
year  after  such  termination  of  employment,  whether  or not the  option was
otherwise  exercisable by him at the time of such termination of employment.  If
the optionee  dies while  employed by the Holding  Company or its  subsidiaries,
within three years after his retirement (or, if later,  six months following his
termination  of  service as a  director  or  director  emeritus  of the  Holding
Company),  or within one year after his  termination  of  employment  because of
permanent and total disability,  his option may be exercised by his estate or by
the person or persons  entitled  thereto  by will or by the  applicable  laws of
descent  or  distribution  at any time  within  one year  after the date of such
death,  whether or not the option was otherwise  exercisable  by the optionee at
the date of his death. Notwithstanding the foregoing, in no event may any option
be  exercised  after  the  expiration  of the  option  term  set  by  the  Stock
Compensation Committee.




     Exercise  of  Options  by  Outside  Directors.  Options  granted to Outside
Directors terminate six months after the date such Outside Director ceases to be
a director and director  emeritus of the Holding  Company for any reason.  If an
optionee  who is an  Outside  Director  ceases to be a  director  and a director
emeritus by reason of disability,  any option granted to him may be exercised in
whole or in part within one year of such termination of service,  whether or not
the option was otherwise  exercisable by him at the time of such  termination of
service.  In the event of the death of an Outside  Director  while  serving as a
director or director emeritus of the Holding Company, within six months after he
ceases to be a director  and a director  emeritus  of the  Holding  Company,  or
within one year after he ceases to be a director and a director  emeritus of the
Holding  Company  by reason of  disability,  any  option  granted  to him may be
exercised by his estate or by the person or persons  entitled thereto by will or
by the applicable  laws of descent or  distribution  at any time within one year
after the date of such death,  whether or not the option was  exercisable by the
optionee at the date of his death.  Notwithstanding  the foregoing,  in no event
may any option be exercised  after the  expiration of the option term set by the
Stock Compensation Committee.

     Nontransferability of Option. Options may not be transferred except by will
or the laws of descent and  distribution  or  pursuant  to a qualified  domestic
relations order. During the lifetime of an optionee,  they may be exercised only
by him or his guardian or legal representative.

     Maximum  Incentive Stock Options.  The aggregate fair market value of stock
with respect to which incentive stock options are exercisable for the first time
by an  optionee  during any  calendar  year under the Option Plan may not exceed
$100,000.  For  purposes of these  computations,  the fair  market  value of the
shares is to be  determined as of the date the option is granted and computed in
the manner determined by the Stock  Compensation  Committee  consistent with the
requirements of the Code. This limitation does not apply to non-qualified  stock
options granted under the Option Plan.

     Cash Awards.  The Stock  Compensation  Committee may grant to optionees who
are granted non-qualified stock options the right to receive a cash amount which
is intended to reimburse the optionee for all or a portion of the federal, state
and local income taxes  imposed upon the optionee as a result of the exercise of
a non-qualified stock option and the receipt of a cash award.

     Replacement  and  Extension  of the Terms of Options and Cash  Awards.  The
Stock Compensation  Committee from time to time may permit an optionee under the
Option Plan or any other stock option plan adopted by the Holding Company or any
of its subsidiaries,  to surrender for cancellation any unexercised  outstanding
stock option and receive from the optionee's  employing  corporation in exchange
therefor  an  option  for  such  number  of  shares  of  Common  Stock as may be
designated  by the Stock  Compensation  Committee.  Such  optionees  may also be
granted related cash awards.

     Change  of  Control.  In the event of a change of  control  of the  Holding
Company,  and  subject to  certain  limitations  set forth in the  Option  Plan,
outstanding options which are not otherwise  exercisable will become immediately
exercisable.  Change of  control,  for this  purpose,  means an  acquisition  of
control of the Holding Company or MFB Financial  within the meaning of 12 C.F.R.
ss. 574.4(a)  (other than a change of control  resulting from a trustee or other
fiduciary  holding shares of Common Stock under an employee  benefit plan of the
Holding  Company or any of its  subsidiaries).  This  provision  could result in
adverse tax  consequences to the Holding Company and to the optionee as a result
of the golden  parachute  provisions  in the Code.  Under the  golden  parachute
provisions,  compensatory  payments  made by the Holding  Company to an employee
following a change in control  which are  contingent  on a change in control and
which exceed  certain  limits based on the average  annual  compensation  of the
employee  for the five  calendar  years  before the  change in  control  are not
deductible by the Holding Company and would subject the optionee to a 20% excise
tax.  The  value  of any  option  which  would  become  immediately  exercisable
following a change in control (the spread  between the then fair market value of
the option  shares and the option  price)  could be deemed to be a  compensatory
payment contingent on a change in control, and, thus, if such amount, when added
to any other  payments  made by the Holding  Company to the  employee  which are
contingent on a change in control,  would exceed the limits described above, the
excess amounts would be non-deductible and subject to the excise tax.




     The  effect of this  change  of  control  provision  which,  under  certain
circumstances, could accelerate benefits to optionholders may be to increase the
cost of a  potential  business  combination  or  acquisition  of  control of the
Holding  Company.  To the  extent  that  this  increased  cost  is  significant,
potential  acquirors may be deterred  from pursuing a transaction  involving the
Holding Company,  and its shareholders may be deprived of an opportunity to sell
their shares at a favorable price.  However, the options which have been granted
to date under the Option Plan are fully exercisable  within six months following
the date of the grant, so the change of control provision described above is not
expected to have a significant  deterrent effect.  Moreover,  to the extent this
provision  could operate to accelerate  benefits under stock options  awarded in
the future,  the Board of Directors believes that the expected benefits of these
provisions in attracting and retaining qualified  management  personnel outweigh
these possible disadvantages.

Other Provisions

     The  Stock  Compensation  Committee  may  provide  for  such  other  terms,
provisions and conditions of an option as are not  inconsistent  with the Option
Plan. The Stock Compensation Committee may also prescribe,  and amend, waive and
rescind rules and  regulations  relating to the Option Plan,  may accelerate the
vesting of stock  options or cash awards  granted or made under the Option Plan,
may make  amendments or  modifications  in the terms and  conditions  (including
exercisability)  of  the  options  relating  to the  effect  of  termination  of
employment  of the  optionees,  and may waive  any  restrictions  or  conditions
applicable to any option or the exercise thereof.

Amendment and Termination

     The Board of  Directors  of the  Holding  Company may amend the Option Plan
from  time to time,  and,  with the  consent  of the  optionee,  the  terms  and
provisions of his option or cash award, provided, however, that (1) no amendment
may,  without the consent of an  optionee,  make any changes in any  outstanding
option or cash award which would adversely affect the rights of the optionee and
(2) without  approval of the holders of at least a majority of the shares of the
Holding Company voting in person or by proxy at a duly constituted  meeting,  or
adjournment  thereof,  the following changes in the Option Plan may not be made:
an increase in the number of shares  reserved for issuance under the Option Plan
(except as permitted by the  antidilutive  provisions  in the Option  Plan);  an
extension of the option terms to more than 10 years and one day from the date of
grant of the  option;  or a  material  modification  of the  class of  employees
eligible to receive  options or cash awards under the Option Plan.  The Board of
Directors of the Holding  Company may  terminate the Option Plan at any time. In
any event, no incentive stock options may be granted under the Stock Option Plan
after January 19, 2008.

Federal Income Tax Consequences

     The grant of incentive and non-qualified stock options will have no federal
tax  consequences  to the  Holding  Company  or the  optionee.  Moreover,  if an
incentive  stock option is  exercised  (a) while the employee is employed by the
Holding Company or its subsidiaries,  (b) within three months after the optionee
ceases to be an employee of the Holding Company or its  subsidiaries,  (c) after
the optionee's  death, or (d) within one year after the optionee ceases to be an
employee of the Holding Company or its subsidiaries if the optionee's employment
is terminated  because of permanent and total disability  (within the meaning of
ss.  22(e)(3) of the Code),  the  exercise of the  incentive  stock  option will
ordinarily have no federal income tax consequences to the Holding Company or the
optionee.  However,  the amount by which the fair market  value of the shares at
the time of exercise  exceeds the option  price of the option  will,  along with
other specified  items, be considered  taxable income in the taxable year of the
optionee  in which the option was  exercised  for  purposes of  determining  the
applicability  of the alternative  minimum tax. As a result,  the exercise of an
incentive  stock  option may subject an optionee to an  alternative  minimum tax
depending on that optionee's particular circumstances.




     On the other hand, the recipient of a non-qualified  stock option generally
will realize taxable ordinary income at the time of exercise of his option in an
amount  equal to the excess of the fair market  value of the shares  acquired at
the time of such  exercise  over the option  price.  A like amount is  generally
deductible  by the Holding  Company for federal  income tax  purposes as of that
date, as long as the Holding Company  withholds  federal income tax with respect
to that taxable amount,  assuming the optionholder's income is subject to income
tax withholding by the Holding Company.  The Option Plan permits,  under certain
circumstances,   holders  of  non-qualified   stock  options  to  satisfy  their
withholding  obligation  by  having  shares  equal in  value  to the  applicable
withholding  taxes withheld from the shares which they would  otherwise  receive
upon the exercise of a non-qualified stock option.

     Upon the sale of the shares  acquired  upon the  exercise  of an  incentive
stock  option no  sooner  than two years  after the grant of the  option  and no
sooner than one year after  receipt of the shares by the  optionee,  any capital
gain  recognized  would be taxed to the optionee at long-term or mid-term rates.
Upon the sale of shares  acquired upon the exercise of an incentive stock option
prior to two years  after  the  grant of an  option  or prior to one year  after
receipt of the shares by the optionee, the optionee will generally recognize, in
the year of  disposition,  ordinary income equal to the lesser of (a) the spread
between  the fair  market  value of the shares on the date of  exercise  and the
exercise price;  and (b) the gain realized upon the disposition of those shares.
The Holding  Company  will be  entitled  to a  deduction  equal to the amount of
income  recognized as ordinary  income by the  optionee,  so long as the Holding
Company  withholds  federal  income  tax with  respect  to that  taxable  amount
(assuming the optionholder's  income is subject to income tax withholding by the
Holding  Company).  If the  spread is the basis for  determining  the  amount of
ordinary  income realized by the optionee,  there will be additional  long-term,
mid-term or short-term capital gain realized if the proceeds of such sale exceed
such spread.

     Upon  the   subsequent   sale  of  shares   acquired  upon  exercise  of  a
non-qualified  stock option,  the optionholder will recognize  long-term capital
gain or loss if the shares are deemed to have been held for more than 18 months,
mid-term  capital  gain or loss if the  shares  have  been held for more than 12
months but less than 18 months, and short-term capital gain or loss in all other
cases.  Currently,  long-term  capital  gains  for  noncorporate  taxpayers  are
generally  taxed  at a  maximum  rate  of 20% and  mid-term  capital  gains  for
noncorporate  taxpayers are generally taxed at a maximum rate of 28%. Short-term
capital gains are taxed at the same rates as ordinary income.

Financial Accounting Consequences

     At this time, neither the grant of incentive or non-qualified stock options
nor the  issuance  of shares  upon  exercise  of such  options  will result in a
compensation  expense  charge to the Holding  Company's  earnings for  financial
accounting purposes,  except that for non-qualified stock options, earnings will
be charged  with the excess,  if any,  of the fair  market  value on the date of
grant over the exercise  price of the option  shares.  Option  proceeds from the
exercise of these  options  and tax savings  from  non-qualified  stock  options
(other  than tax  savings  resulting  from  charges  to  earnings  made when the
exercise  price is less than fair market value of the option  shares on the date
of grant) are credited to capital. The Financial Accounting Standards Board (the
"FASB") has adopted rules that require  increased  disclosure about the value of
stock options in financial  statements for the Holding Company,  including their
impact on earnings.

     THE BOARD OF DIRECTORS  RECOMMENDS  THAT  SHAREHOLDERS  VOTE TO APPROVE AND
RATIFY THE OPTION PLAN.  SUCH ACTION  REQUIRES THE APPROVAL OF THE HOLDERS OF AT
LEAST A MAJORITY OF THE SHARES OF THE HOLDING  COMPANY'S  COMMON STOCK VOTING IN
PERSON  OR BY  PROXY  AND  ENTITLED  TO  VOTE  AT  THE  ANNUAL  MEETING,  OR ANY
ADJOURNMENT  THEREOF.  ABSTENTIONS  WILL BE  INCLUDED  IN THE  NUMBER  OF SHARES
PRESENT AND  ENTITLED TO VOTE ON THE PROPOSAL  AND  ACCORDINGLY  TREATED AS "NO"
VOTES,  BUT BROKER  NON-VOTES WILL BE EXCLUDED FROM THE NUMBER OF SHARES PRESENT
AND ENTITLED TO VOTE ON THE PROPOSAL AND WILL HAVE NO EFFECT ON THE VOTE.




                    PROPOSAL III -- RATIFICATION OF AUDITORS

     The Board of Directors proposes for the ratification of the shareholders at
the Annual Meeting the appointment of Crowe,  Chizek and Company LLP,  certified
public accountants,  as independent auditors for the fiscal year ended September
30, 1998. Crowe, Chizek and Company LLP has served as auditors for MFB Financial
since 1977. A representative of Crowe, Chizek and Company LLP will be present at
the Annual Meeting with the opportunity to make a statement if he so desires. He
will also be available to respond to any appropriate questions  shareholders may
have.

             SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

     Section 16(a) of the  Securities  and Exchange Act of 1934, as amended (the
"1934 Act"),  requires  that the Holding  Company's  officers and  directors and
persons who own more than 10% of the Holding Company's Common Stock file reports
of  ownership  and  changes  in  ownership  with  the  Securities  and  Exchange
Commission (the "SEC").  Officers,  directors and greater than 10%  shareholders
are required by SEC  regulations  to furnish the Holding  Company with copies of
all Section 16(a) forms that they file.

     Based  solely on its  review of the copies of such  forms  received  by it,
and/or written  representations  from certain  reporting persons that no Forms 5
were required for those persons,  the Holding  Company  believes that during the
fiscal year ended September 30, 1997, all filing requirements  applicable to its
officers,  directors  and greater  than 10%  beneficial  owners with  respect to
Section  16(a)  of the 1934 Act were  satisfied  in a timely  manner;  provided,
however that Marian K. Torian was approximately two months late in reporting the
exercise of a stock  option for 1,000 shares and  simultaneous  sale on the open
market of 550 of those shares.

                              SHAREHOLDER PROPOSALS

     Any  proposal  which a  shareholder  wishes to have  presented  at the next
Annual  Meeting of the  Holding  Company and  included in the Holding  Company's
proxy  statement,  must be received at the main office of the Holding Company no
later than 120 days in advance of December 15, 1998. Any such proposal should be
sent to the  attention  of the  Secretary  of the  Holding  Company at 121 South
Church Street, Mishawaka, Indiana, 46544.

                                  OTHER MATTERS

     Management  is not aware of any business to come before the Annual  Meeting
other than those matters described in the Proxy Statement. However, if any other
matters should properly come before the Annual Meeting,  it is intended that the
proxies  solicited  hereby will be voted with respect to those other  matters in
accordance with the judgment of the persons voting the proxies.

     The cost of solicitation  of proxies will be borne by the Holding  Company.
The  Holding  Company  will  reimburse  brokerage  firms and  other  custodians,
nominees and  fiduciaries  for reasonable  expenses  incurred by them in sending
proxy  material to the  beneficial  owners of the Common  Stock.  In addition to
solicitation by mail, directors,  officers, and employees of the Holding Company
may solicit proxies personally or by telephone without additional compensation.

     Each  shareholder is urged to complete,  date and sign the proxy and return
it promptly in the enclosed envelope.

                                            Charles J. Viater, President
December 15, 1997



                                    MFB CORP.

                             1997 STOCK OPTION PLAN



         1.  Purpose.  The purpose of the MFB Corp.  1997 Stock Option Plan (the
"Plan") is to provide to  directors,  officers  and other key  employees  of MFB
Corp.  (the  "Holding   Company")  and  its   majority-owned   and  wholly-owned
subsidiaries  (individually a "Subsidiary" and collectively the "Subsidiaries"),
including,  but not  limited  to,  MFB  Financial  ("MFB"),  who are  materially
responsible  for the  management  or  operation  of the  business of the Holding
Company or a  Subsidiary  and have  provided  valuable  services  to the Holding
Company or a  Subsidiary,  a  favorable  opportunity  to acquire  Common  Stock,
without par value ("Common  Stock"),  of the Holding Company,  thereby providing
them with an increased  incentive to work for the success of the Holding Company
and its  Subsidiaries and better enabling each such entity to attract and retain
capable directors and executive personnel.

         2.  Administration  of  the  Plan.  The  Plan  shall  be  administered,
construed and  interpreted  by a committee  (the  "Committee")  consisting of at
least two members of the Board of Directors of the Holding Company, each of whom
is a "Non-Employee  Director"  within the meaning of the definition of that term
contained in Reg. ss. 16b-3  promulgated  under the  Securities  Exchange Act of
1934,  as amended  (the "1934  Act").  The  members  of the  Committee  shall be
designated  from time to time by the Board of Directors of the Holding  Company.
The decision of a majority of the members of the Committee shall  constitute the
decision  of the  Committee,  and the  Committee  may act either at a meeting at
which a  majority  of the  members of the  Committee  is present or by a written
consent  signed by all members of the  Committee.  The Committee  shall have the
sole, final and conclusive  authority to determine,  consistent with and subject
to the provisions of the Plan:

               (a)  the  individuals  (the   "Optionees")  to  whom  options  or
          successive options or cash awards shall be granted under the Plan;

               (b) the  time  when  options  or cash  awards  shall  be  granted
          hereunder;

               (c) the number of shares of Common Stock to be covered under each
          option and the amount of any cash awards;

               (d) the option price to be paid upon the exercise of each option;

               (e) the period within which each such option may be exercised;

               (f) the extent to which an option is an incentive stock option or
          a non-qualified stock option; and

               (g) the terms and  conditions  of the  respective  agreements  by
          which options granted or cash awards shall be evidenced.

The Committee shall also have authority to prescribe,  amend, waive, and rescind
rules and  regulations  relating to the Plan, to  accelerate  the vesting of any
stock options or cash awards made hereunder, to make amendments or modifications
in the terms and conditions  (including  exercisability) of the options relating
to the effect of termination of employment of the optionee  (subject to the last
sentence  of  Section  12  hereof),  to waive  any  restrictions  or  conditions
applicable  to any  option  or the  exercise  thereof,  and to  make  all  other
determinations necessary or advisable in the administration of the Plan.




         3. Eligibility.  The Committee may, consistent with the purposes of the
Plan,  grant  options  and cash  awards  to  officers,  directors  and other key
employees of the Holding  Company or of a  Subsidiary  who in the opinion of the
Committee are from time to time  materially  responsible  for the  management or
operation  of the business of the Holding  Company or of a  Subsidiary  and have
provided  valuable  services to the Holding  Company or a Subsidiary;  provided,
however,  that in no event may any employee who owns (after  application  of the
ownership  rules in ss. 425(d) of the Internal  Revenue Code of 1986, as amended
(the  "Code"))  shares of stock  possessing  more than 10  percent  of the total
combined  voting power of all classes of stock of the Holding  Company or any of
its  Subsidiaries be granted an incentive stock option  hereunder  unless at the
time such option is granted the option price is at least 110% of the fair market
value of the stock  subject to the  option  and such  option by its terms is not
exercisable  after the expiration of five (5) years from the date such option is
granted.  An  individual  who has been  granted  an  option  under  the Plan (an
"Optionee"), if he is otherwise eligible, may be granted an additional option or
options if the Committee shall so determine.

         4. Stock Subject to the Plan. There shall be reserved for issuance upon
the exercise of options  granted under the Plan,  150,000 shares of Common Stock
of the Holding Company,  which may be authorized but unissued shares or treasury
shares of the Holding Company. Subject to Section 7 hereof, the shares for which
options  may be  granted  under the Plan shall not exceed  that  number.  If any
option shall expire or terminate or be surrendered for any reason without having
been exercised in full, the unpurchased shares subject thereto shall (unless the
Plan shall have terminated) become available for other options under the Plan.

         5.  Terms of  Options.  Each  option  granted  under the Plan  shall be
subject  to the  following  terms and  conditions  and to such  other  terms and
conditions not  inconsistent  therewith as the Committee may deem appropriate in
each case:

              (a)  Option  Price.  The price to be paid for shares of stock upon
         the exercise of each option shall be determined by the Committee at the
         time such option is  granted,  but such price in no event shall be less
         than the fair market value,  as determined by the Committee  consistent
         with Treas.  Reg. ss. 20.2031-2 and any requirements of ss. 422A of the
         Code,  of such  stock on the  date on which  such  option  is  granted;
         provided,  however that the  Committee  shall have  discretion to award
         non-qualified  stock options to eligible  employees or directors of the
         Holding  Company or of a Subsidiary  at a price no less than 85% of the
         fair  market  value  of the  Common  Stock  on the  date of  grant,  as
         determined by the Committee consistent with Treas. Reg ss. 20.2031-2.

              (b)  Period  for  Exercise  of  Option.  An  option  shall  not be
         exercisable  after the  expiration  of such period as shall be fixed by
         the Committee at the time of the grant  thereof,  but such period in no
         event  shall  exceed  ten (10) years and one day from the date on which
         such option is granted;  provided, that incentive stock options granted
         hereunder  shall  have  terms  not in  excess  of ten  (10)  years  and
         non-qualified  stock options shall be for a period not in excess of ten
         (10) years and one day from the date of grant thereof. Options shall be
         subject to earlier termination as hereinafter provided.

              (c)  Exercise of Options.  The option price of each share of stock
         purchased  upon exercise of an option shall be paid in full at the time
         of such exercise.  Payment may be in (i) cash, (ii) if the Optionee may
         do so in  conformity  with  Regulation  T (12 C.F.R.  ss.  220.3(e)(4))
         without violating ss. 16(b) or ss. 16(c) of the 1934 Act, pursuant to a
         broker's cashless exercise procedure, by delivering a properly executed
         exercise notice together with  irrevocable  instructions to a broker to
         promptly  deliver to the Holding Company the total option price in cash
         and,  if  desired,  the  amount  of any taxes to be  withheld  from the
         Optionee's  compensation  as a result of any withholding tax obligation
         of the Holding Company or any of its Subsidiaries, as specified in such
         notice, or (iii) with the approval of the Committee, by tendering whole
         shares of the Holding  Company's Common Stock owned by the Optionee and
         cash having a fair market value equal to the cash exercise price of the
         shares with  respect to which the option is being  exercised.  For this
         purpose,  any shares so tendered by an Optionee shall be deemed to have



         a fair market  value  equal to the mean  between the highest and lowest
         quoted  selling  prices for the shares on the date of  exercise  of the
         option (or if there were no sales on such date the weighted  average of
         the means between the highest and lowest quoted  selling prices for the
         shares on the nearest  date before and the nearest  date after the date
         of exercise of the options as prescribed by Treas. Reg. ss. 20-2031-2),
         as  reported  in The  Wall  Street  Journal  or a  similar  publication
         selected by the  Committee.  The Committee  shall have the authority to
         grant  options  exercisable  in full at any time during their term,  or
         exercisable in such installments at such times during their term as the
         Committee may determine;  provided,  however, that options shall not be
         exercisable during the first six (6) months of their term. Installments
         not  purchased in earlier  periods  shall be cumulated and be available
         for purchase in later periods.  Subject to the other provisions of this
         Plan,  an  option  may be  exercised  at any time or from  time to time
         during the term of the option as to any or all whole  shares which have
         become  subject to purchase  pursuant to the terms of the option or the
         Plan,  but not at any time as to fewer than one  hundred  (100)  shares
         unless the remaining  shares which have become  subject to purchase are
         fewer than one hundred (100) shares. An option may be exercised only by
         written notice to the Holding  Company,  mailed to the attention of its
         Secretary,  signed by the  Optionee (or such other person or persons as
         shall demonstrate to the Holding Company his or their right to exercise
         the option),  specifying the number of shares in respect of which it is
         being  exercised,  and accompanied by payment in full in either cash or
         by check in the amount of the aggregate  purchase  price  therefor,  by
         delivery of the irrevocable broker instructions  referred to above, or,
         if the  Committee  has  approved  the  use of the  stock  swap  feature
         provided for above,  followed as soon as practicable by the delivery of
         the option price for such shares.

              (d)  Certificates.  The certificate or certificates for the shares
         issuable  upon an exercise of an option  shall be issued as promptly as
         practicable after such exercise.  An Optionee shall not have any rights
         of a shareholder in respect to the shares of stock subject to an option
         until  the  date of  issuance  of a stock  certificate  to him for such
         shares.  In no case may a fraction  of a share be  purchased  or issued
         under the Plan,  but if, upon the  exercise of an option,  a fractional
         share would  otherwise be issuable,  the Holding Company shall pay cash
         in lieu thereof.

              (e)  Termination of Option.  If an Optionee (other than a director
         of the Holding  Company or a  Subsidiary  who is not an employee of the
         Holding Company or a Subsidiary (an "Outside  Director"))  ceases to be
         an employee of the Holding Company and the  Subsidiaries for any reason
         other than  retirement,  permanent  and total  disability  (within  the
         meaning of ss. 22(e)(3) of the Code),  or death,  any option granted to
         him  shall  forthwith  terminate.  Leave  of  absence  approved  by the
         Committee shall not constitute cessation of employment.  If an Optionee
         (other  than an  Outside  Director)  ceases  to be an  employee  of the
         Holding  Company  and the  Subsidiaries  by reason of  retirement,  any
         option  granted  to him may be  exercised  by him in  whole  or in part
         within three (3) years after the date of his retirement, whether or not
         the option was  otherwise  exercisable  at the date of his  retirement;
         provided, however, that if such employee remains a director or director
         emeritus  of the  Holding  Company,  the  option  granted to him may be
         exercised  by him in whole or in part  until the later of (a) three (3)
         years  after the date of his  retirement,  or (b) six months  after his
         service as a director  or  director  emeritus  of the  Holding  Company
         terminates.   (The  term   "retirement"   as  used  herein  means  such
         termination of employment as shall entitle such  individual to early or
         normal retirement  benefits under any then existing pension plan of the
         Holding Company or a Subsidiary.) If an Optionee (other than an Outside
         Director)  ceases to be an  employee  of the  Holding  Company  and the
         Subsidiaries  by reason of permanent and total  disability  (within the
         meaning of ss. 22(e)(3) of the Code),  any option granted to him may be
         exercised by him in whole or in part within one (1) year after the date
         of his termination of employment by reason of such  disability  whether
         or not  the  option  was  otherwise  exercisable  at the  date  of such
         termination.  Options  granted to Outside  Directors  shall cease to be



         exercisable  six (6) months after the date such Outside  Director is no
         longer a director  or director  emeritus  of the  Holding  Company or a
         Subsidiary  for any  reason  other  than  death  or  disability.  If an
         Optionee  who is an  Outside  Director  ceases to be a  director  and a
         director  emeritus by reason of  disability,  any option granted to him
         may be exercised in whole or in part within one (1) year after the date
         the Optionee ceases to be a director and a director  emeritus by reason
         of such disability, whether or not the option was otherwise exercisable
         at such  date.  In the event of the death of an  Optionee  while in the
         employ or service as a director  or  director  emeritus  of the Holding
         Company  or a  Subsidiary,  or,  if the  Optionee  is  not  an  Outside
         Director,  within three (3) years after the date of his retirement (or,
         if later, six months following his termination of service as a director
         or director  emeritus of the Holding Company or a Subsidiary) or within
         one (1) year  after  the  termination  of his  employment  by reason of
         permanent and total  disability  (within the meaning of ss. 22(e)(3) of
         the Code), or, if the Optionee is an Outside  Director,  within six (6)
         months after he is no longer a director and a director  emeritus of the
         Holding  Company or of Subsidiary for reasons other than disability or,
         within one (1) year after the  termination  of his service by reason of
         disability,  any option  granted to him may be exercised in whole or in
         part at any time  within  one (1) year  after the date of such death by
         the executor or administrator of his estate or by the person or persons
         entitled  to the option by will or by  applicable  laws of descent  and
         distribution  until the  expiration  of the option term as fixed by the
         Committee,  whether or not the option was otherwise  exercisable at the
         date of his death.  Notwithstanding  the  foregoing  provisions of this
         subsection  (e), no option shall in any event be exercisable  after the
         expiration  of the period  fixed by the  Committee in  accordance  with
         subsection (b) above.

              (f)  Nontransferability of Option. No option may be transferred by
         the  Optionee  otherwise  than  by  will or the  laws  of  descent  and
         distribution  or pursuant to a qualified  domestic  relations  order as
         defined  by the  Code or  Title  I of the  Employee  Retirement  Income
         Security Act, or the rules  thereunder,  and during the lifetime of the
         Optionee  options  shall be  exercisable  only by the  Optionee  or his
         guardian or legal representative.

              (g) No Right to Continued Service.  Nothing in this Plan or in any
         agreement  entered into pursuant  hereto shall confer on any person any
         right to continue  in the employ or service of the  Holding  Company or
         its  Subsidiaries  or  affect  any  rights  the  Holding   Company,   a
         Subsidiary,  or the  shareholders  of the  Holding  Company may have to
         terminate his service at any time.

              (h) Maximum  Incentive  Stock  Options.  The aggregate fair market
         value of stock with respect to which  incentive  stock options  (within
         the meaning of ss. 422A of the Code) are exercisable for the first time
         by an  Optionee  during any  calendar  year under the Plan or any other
         plan of the  Holding  Company  or its  Subsidiaries  shall  not  exceed
         $100,000.  For this purpose, the fair market value of such shares shall
         be  determined  as of the date  the  option  is  granted  and  shall be
         computed  in such  manner  as shall  be  determined  by the  Committee,
         consistent with the requirements of ss. 422A of the Code.

              (i)  Agreement.  Each option  shall be  evidenced  by an agreement
         between the Optionee and the Holding Company which shall provide, among
         other  things,  that,  with respect to  incentive  stock  options,  the
         Optionee will advise the Holding Company  immediately  upon any sale or
         transfer of the shares of Common Stock  received  upon  exercise of the
         option to the extent  such sale or  transfer  takes  place prior to the
         later of (a) two (2)  years  from the date of grant or (b) one (1) year
         from the date of exercise.




              (j)  Investment  Representations.  Unless the shares subject to an
         option are registered  under  applicable  federal and state  securities
         laws, each Optionee by accepting an option shall be deemed to agree for
         himself and his legal  representatives  that any option  granted to him
         and any and all shares of Common Stock  purchased  upon the exercise of
         the option shall be acquired for  investment and not with a view to, or
         for the sale in connection  with, any  distribution  thereof,  and each
         notice of the exercise of any portion of an option shall be accompanied
         by a  representation  in writing,  signed by the  Optionee or his legal
         representatives,  as the case may be,  that the shares of Common  Stock
         are being acquired in good faith for investment and not with a view to,
         or for sale in connection  with, any  distribution  thereof  (except in
         case of the Optionee's legal representatives for distribution,  but not
         for  sale,  to  his  legal  heirs,   legatees  and  other  testamentary
         beneficiaries).  Any shares issued pursuant to an exercise of an option
         may bear a legend evidencing such representations and restrictions.

         6. Incentive  Stock Options and  Non-Qualified  Stock Options.  Options
granted under the Plan may be incentive stock options under ss. 422A of the Code
or non-qualified stock options, provided,  however, that Outside Directors shall
be granted only non-qualified stock options.  All options granted hereunder will
be clearly  identified as either incentive stock options or non-qualified  stock
options.  In no event will the exercise of an incentive  stock option affect the
right to exercise any non-qualified  stock option, nor shall the exercise of any
non-qualified  stock  option  affect the right to exercise any  incentive  stock
option.  Nothing  in this  Plan  shall be  construed  to  prohibit  the grant of
incentive  stock  options and  non-qualified  stock  options to the same person,
provided,  further, that incentive stock options and non-qualified stock options
shall not be granted in a manner whereby the exercise of one non-qualified stock
option or incentive stock option affects the exercisability of the other.

         7. Adjustment of Shares. In the event of any change after the effective
date of the Plan in the  outstanding  stock of the Holding  Company by reason of
any reorganization,  recapitalization,  stock split, stock dividend, combination
of  shares,   exchange  of  shares,   merger  or   consolidation,   liquidation,
extraordinary distribution (consisting of cash, securities, or other assets), or
any other  change  after  the  effective  date of the Plan in the  nature of the
shares of stock of the Holding  Company,  the  Committee  shall  determine  what
changes, if any, are appropriate in the number and kind of shares reserved under
the  Plan,  and  the  Committee  shall  determine  what  changes,  if  any,  are
appropriate  in the option price under and the number and kind of shares covered
by  outstanding  options  granted  under  the  Plan.  Any  determination  of the
Committee hereunder shall be conclusive.

         8. Cash Awards.  The Committee may, at any time and in its  discretion,
grant to any Optionee who is granted a  non-qualified  stock option the right to
receive, at such times and in such amounts as determined by the Committee in its
discretion,  a cash amount  ("cash  award")  which is intended to reimburse  the
Optionee  for all or a portion  of the  federal,  state and local  income  taxes
imposed upon such Optionee as a consequence  of the exercise of a  non-qualified
stock option and the receipt of a cash award.

         9.  Replacement  and Extension of the Terms of Options and Cash Awards.
The  Committee  from time to time may permit an  Optionee  under the Plan or any
other stock option plan  heretofore or hereafter  adopted by the Holding Company
or any  Subsidiary to surrender for  cancellation  any  unexercised  outstanding
stock option and receive from his employing  corporation in exchange therefor an
option for such  number of shares of Common  Stock as may be  designated  by the
Committee. Such Optionees also may be granted related cash awards as provided in
Section 8 hereof.

         10. Change in Control. In the event of a Change in Control, all options
previously  granted and still  outstanding  under the Plan  regardless  of their
terms,  shall become  exercisable.  For this purpose,  "Change in Control" shall
mean a change in control of the Holding Company or MFB, within the meaning of 12
C.F.R. ss. 574.4(a) (other than a change of control  resulting from a trustee or
other fiduciary holding shares of Common Stock under an employee benefit plan of
the Holding Company or any of its Subsidiaries).




         11. Tax  Withholding.  Whenever  the  Holding  Company  proposes  or is
required to issue or transfer shares of Common Stock under the Plan, the Holding
Company  shall  have the  right to  require  the  Optionee  or his or her  legal
representative  to remit to the Holding Company an amount  sufficient to satisfy
any federal,  state  and/or  local  withholding  tax  requirements  prior to the
delivery of any certificate or certificates for such shares,  and whenever under
the Plan  payments  are to be made in  cash,  such  payments  shall be net of an
amount  sufficient to satisfy any federal,  state and/or local  withholding  tax
requirements.   If  permitted  by  the  Committee  and  pursuant  to  procedures
established  by the Committee,  an Optionee may make a written  election to have
shares of Common Stock having an aggregate  fair market value,  as determined by
the Committee,  consistent with the requirements of Treas.  Reg. ss.  20.2031-2,
sufficient to satisfy the applicable withholding taxes, withheld from the shares
otherwise to be received upon the exercise of a non-qualified option.

         12. Amendment.  The Board of Directors of the Holding Company may amend
the Plan from time to time and, with the consent of the Optionee,  the terms and
provisions of his option or cash award,  except that without the approval of the
holders of at least a majority  of the shares of the Holding  Company  voting in
person or by proxy at a duly constituted meeting or adjournment thereof:

                  (a) the number of shares of stock  which may be  reserved  for
         issuance  under the Plan may not be  increased,  except as  provided in
         Section 7 hereof;

                  (b) the period during which an option may be exercised may not
         be  extended  beyond  ten (10) years and one day from the date on which
         such option was granted; and

                  (c) the class of persons to whom options or cash awards may be
         granted under the Plan shall not be modified materially.

         No  amendment  of the Plan,  however,  may,  without the consent of the
Optionees,   make  any  changes  in  any  outstanding  options  or  cash  awards
theretofore  granted under the Plan which would  adversely  affect the rights of
such Optionees.

         13.  Termination.  The Board of  Directors  of the Holding  Company may
terminate  the Plan at any time and no option  or cash  award  shall be  granted
thereafter.  Such  termination,  however,  shall not affect the  validity of any
option or cash  award  theretofore  granted  under the Plan.  In any  event,  no
incentive stock option may be granted under the Plan after the date which is ten
(10) years from the effective date of the Plan.

         14.  Successors.  This Plan shall be binding  upon the  successors  and
assigns of the Holding Company.

         15.  Governing Law. The terms of any options granted  hereunder and the
rights and obligations hereunder of the Holding Company, the Optionees and their
successors in interest shall be governed by Indiana law.

         16.  Government and Other  Regulations.  The obligations of the Holding
Company to issue or transfer and deliver shares under options  granted under the
Plan or make cash  awards  shall be subject to  compliance  with all  applicable
laws, governmental rules and regulations, and administrative action.

         17.  Effective  Date.  The Plan shall become  effective on the date the
Plan is  approved  by the  holders of at least a  majority  of the shares of the
Holding  Company voting in person or by proxy at a duly  constituted  meeting or
adjournment  thereof  and any  options  granted  pursuant to the Plan may not be
exercised  until the Board of Directors of the Holding  Company has been advised
by counsel that such approval has been obtained and all other  applicable  legal
requirements have been met.
