with a further  incentive  to continue as  directors of the Company and increase
shareholder value.

conclusive.  No member of the Board  shall be  liable  for any  action  taken or
decision  made in good faith  relating  to the Plan or any Option or  Restricted

5.       Eligibility

         Each Outside  Director of the Company shall be eligible to  participate
in the Plan.

6.       Terms and Conditions of Options

         Each  option  granted  under the Plan  shall be  evidenced  by a signed
written agreement in such form as the Board shall prescribe from time to time in
accordance  with the  Plan,  and  shall  comply  with the  following  terms  and
conditions:

         (a) Automatic Grant of Options. On the first business day of January of
each year,  each Outside  Director who is a director of the Company on such date
shall  automatically  be granted an Option for one thousand five hundred (1,500)
Shares.  All Options granted under the Plan shall be nonqualified stock options.
The  purchase  price of a Share under each Option shall be the Fair Market Value
of a Share on the date of grant.

         (b) Exercisability and Period of Option. Each Option shall become first
exercisable  one year  after  the date  upon  which  it was  granted,  provided,
however,  that  any  Option  granted  pursuant  to the Plan  shall,  if not then
exercisable,  become  exercisable  in full upon the  retirement  of the  Outside
Director  because of age  ("Retirement")  or total and permanent  disability (as
determined  in the sole  discretion  of the  Board),  or upon  the  death of the
Outside  Director.  No Option shall be  exercisable  after the expiration of ten
(10) years from the date upon which such Option is granted. Each Option shall be
subject to termination before its date of expiration as provided in Section 7.

         (c) Notice of Exercise and Payment.  An Option  granted  under the Plan
may be  exercised  by the  optionee  giving  written  notice of  exercise to the
Secretary of the Company. The Option price for Shares purchased shall be paid in
full at the time such notice is given.  An Option  shall be deemed  exercised on
the date the Secretary  receives written notice of exercise,  together with full
payment for the Shares purchased.  The Option price shall be paid to the Company
either in cash,  by  delivery  to the  Company  of Shares  already  owned by the
optionee  or  in  any  combination  of  cash  and  such  Shares.  In  the  event
already-owned  Shares are used to pay all or a portion of the Option price,  the
amount credited to payment of the Option price shall be the Fair Market Value of
the already-owned Shares on the date the Option is exercised.

         (d) Fractional Shares. No fractional Shares shall be issued pursuant to
the  exercise  of  an  Option,  nor shall any  cash  payment be  made in lieu of
fractional Shares.

         (e) Options Nontransferable.  Each Option granted under the Plan shall,
by its terms, be  nontransferable  otherwise than by will or the laws of descent
and  distribution,  and an Option may be  exercised,  during the lifetime of the
Outside  Director,  only by such  Outside  Director  or,  if  permissible  under
applicable law, by the Outside Director's guardian or legal  representative.  No
Option  or  interest  therein  may  be  transferred,   assigned,   pledged,   or
hypothecated by the optionee during his or her lifetime  whether by operation of
law or  otherwise,  or be made  subject  to  execution,  attachment,  or similar
process.

7.       Termination of Service

         (a)  Termination  of Service Other Than Due to Retirement or Death.  In
the event that an Outside  Director shall cease to be a director,  other than by
reason of Retirement or death, then the Outside Director may exercise the Option
during the nine (9)-month period following such  termination,  but, in no event,
after  the  expiration  of the  Option.  In the  event  that the  Option  is not
exercised  during the nine  (9)-month  period  following  termination,  it shall
expire at the end of such nine  (9)-month  period.  In the event that an Outside
Director  ceases to be a director  other than by reason of  Retirement or death,
and then dies during the nine (9)-month  period  following  such  termination of
service as a director, then the Option may be exercised by a legatee or legatees
of the Outside Director under his last will, or by his personal  representatives
or  distributees,  at any time  within a period of one year  after  the  Outside
Director's death, but, in no event, after expiration of the Option. In the event
that the Option is not  exercised  during the one-year  period after the Outside
Director's death, then it shall expire at the end of such one-year period.

         (b) Retirement. In the event that an Outside Director shall cease to be
a director  because of  Retirement,  then the Outside  Director may exercise the
Option at any time during the remaining term of the Option. In the event that an
Outside Director dies following Retirement,  then the Option theretofore granted
to the Outside Director may be exercised by a legatee or legatees of the Outside
Director   under  his  last  will,  or  by  his  personal   representatives   or
distributees, at any time during the remaining term of the Option.

         (c) Death.  In the event that an Outside  Director  shall cease to be a
director because of death,  then the Option  theretofore  granted to the Outside
Director may be exercised by a legatee or legatees of the Outside Director under
his last will, or by his personal  representatives or distributees,  at any time
during the remaining term of the Option.

8.       Restricted Share Awards

         The Board may issue Restricted  Shares to a Director which Shares shall
be subject  to the  following  terms and  conditions  and such  other  terms and
conditions  as the  Board  may  prescribe  in  connection  with  the  grant of a
Restricted Share Award:

         (a)  General.  With  respect to each grant of  Restricted  Shares,  the
Board,  in its sole  discretion,  shall  determine  the period  during which the
restrictions  set forth at Subsection 8(a) shall apply to the Restricted  Shares
(the "Restricted Period").

         (b)  Restrictions.  At the  time of  grant of  Restricted  Shares  to a
Director,  a  certificate  representing  the number of shares  granted  shall be
registered  in his name but shall be held by the  Company for the account of the
Director.  The Director shall have the entire beneficial  ownership interest in,
and all rights and  privileges of a shareholder as to, such  Restricted  Shares,
including the right to receive  dividends and the right to vote such  Restricted
Shares, subject to the following restrictions:  (i) subject to Section 8(c), the
Director  shall not be entitled to delivery of the Share  certificate  until the
expiration of the Restricted  Period;  (ii) none of the Restricted Shares may be
sold,  transferred,  assigned,  pledged, or otherwise  encumbered or disposed of
during the Restricted  Period;  and (iii) all of the Restricted  Shares shall be
forfeited  and all  rights  of the  Director  to such  Restricted  Shares  shall
terminate  without  further  obligation  on the part of the  Company  unless the
Director remains a Director of the Company for the entire  Restricted  Period in
relation to which such  Restricted  Shares were  granted,  except as provided by
Section 8(c). Any Shares received with respect to Restricted  Shares as a result
of a  recapitalization  adjustment  pursuant to Section 3(b) shall be subject to
the same restrictions as such Restricted Shares.

         (c)  Termination of Service as a Director.

                  (i)  Retirement.  If a Director ceases to be a Director of the
Company prior to the end of a Restricted Period by reason of retirement with the
consent  of the  Company,  the  number of  Restricted  Shares  remaining  in the
Director's  account  shall vest in the  Director  and all  restrictions  on such
number of Shares shall lapse.  A certificate  for such Shares shall be delivered
to the Director in accordance with the provisions of Section 8(d) hereof.

                  (ii)  Death.  If a  Director  ceases to be a  Director  of the
Company  prior  to the end of a  Restricted  Period  by  reason  of  death,  the
Restricted  Shares  granted  to  such  Director  shall  immediately  vest in his
beneficiary  or estate and all  restrictions  applicable  to such  Shares  shall
lapse.  A  certificate  for such Shares  shall be  delivered  to the  Director's
beneficiary or estate in accordance with the provisions of Subsection 8(d).

                  (iii) All Other  Terminations.  If a  Director  ceases to be a
Director  prior to the end of a  Restricted  Period  for any  reason  other than
retirement  or death,  the Director  shall  immediately  forfeit all  Restricted
Shares then subject to the  restrictions  of Section 8(b) in accordance with the
provisions   thereof,   except  that  the  Board  may,  if  it  finds  that  the
circumstances  in the  particular  case  so  warrant,  allow  a  Director  whose
employment has so terminated to retain any or all of the Restricted  Shares then
subject to the restrictions of Section 8(b) and all  restrictions  applicable to
such retained  shares shall lapse. A certificate  for such retained shares shall
be delivered to the Director in accordance with the provisions of Section 8(d).

         (d) Payment of Restricted  Shares.  At the end of the Restricted Period
or at such earlier time as provided for in  Subsection  8(c),  all  restrictions
applicable to the Restricted  Shares shall lapse and a Share  certificate  for a
number  of  Shares  equal  to the  number  of  Restricted  Shares,  free  of all
restrictions,  shall be delivered to the Director or his  beneficiary or estate,
as the case may be.

9.       Limitation of Rights

         Neither the Plan,  nor the  granting of an Option or  Restricted  Share
award nor any other action  taken  pursuant to the Plan shall  constitute  or be
evidence of any agreement or understanding, express or implied, that the Company
will retain an Outside  Director  for any period of time,  or at any  particular
rate of compensation.

10.      Compliance with Laws and Exchange Requirements

         No Option or  Restricted  Share  grant  shall be granted  and no Shares
shall be issued in  connection  with any Option  unless the Option or Restricted
Share grant and the issuance and delivery of Shares upon  exercise of the Option
or Restricted Share grant shall comply with all relevant provisions of state and
federal law,  including,  without  limitation,  the  Securities Act of 1933, the
Securities  Exchange  Act  of  1934,  the  rules  and  regulations   promulgated
