9.   Withholding
     -----------

     The  Company  shall  have the right to deduct  and  withhold  from any cash
otherwise  payable  to  a  Participant,  or  require  that  a  Participant  make
arrangements  satisfactory  to the Company  for payment of, such  amounts as the
Company shall  determine for the purpose of satisfying its liability to withhold
federal,  state or local income or FICA taxes incurred by reason of the grant or
exercise of an option. In the discretion of the Committee,  a Participant may be
permitted  to  satisfy  the  Company's  withholding  requirements  by  tendering
previously  acquired  Shares or by electing to have the Company  withhold Shares
otherwise  issuable to the Participant,  having a fair market value, on the date
income is recognized  pursuant to the exercise of a Non-Qualified  Stock Option,
in the amount required to be withheld. The election shall be made in writing and
shall be made  according to such rules and in such form as the  Committee  shall
determine.

10.  Exercise of Options
     -------------------

     Each option  granted under the Option Plan will be exercisable on such date
or dates  and  during  such  period  and for such  number  of Shares as shall be
determined  pursuant to the provisions of the option  agreement  evidencing such
option. Subject to the provisions of the Plan, the Committee shall have complete
authority,  in its  discretion,  to  determine  the  extent,  if  any,  and  the
conditions  under which an option may be  exercised in the event of the death of
the Participant or in the event the Participant leaves the employ of the Company
or has his  employment  terminated  by the Company.  The  purchase  price of any
option may be paid (a) in cash or its  equivalent;  (b) with the  consent of the
Committee,  by tendering  (including by attestation)  previously acquired Shares
valued at their fair market value as  determined by the  Committee;  or (c) with
the consent of the Committee,  by electing to have the Company  withhold  Shares
otherwise issuable to the Participant, having a fair market value on the date of
exercise of a Non-Qualified  stock option, in the amount required to be paid; or
with the consent of the Committee,  by any combination of (a), (b), and (c). Any
election  under  (b) or (c)  above  shall be made in  writing  and shall be made
according to such rules and in such form as the Committee shall  determine.  The
Committee may provide one or more means to enable  Participants  and the Company
to defer delivery of Shares otherwise deliverable upon exercise of an option, on
such terms and  conditions as the Committee may  determine,  including by way of
example the manner and timing of making a deferral  election,  the  treatment of
dividends  paid on the Shares  during  the  deferral  period  and the  permitted
distribution  dates or events.  No such deferral means may result in an increase
in the number of shares of Common Stock issuable hereunder.

11.  Transferability
     ---------------

     Options under the Plan are not  transferable  otherwise than by will or the
laws of descent or  distribution,  except that a Participant  may, to the extent
allowed by the Committee and in the manner specified by the Committee,  transfer
any option grant


                                       4


award. The Committee shall have authority, in its discretion,  to amend existing
stock option  agreements and to allow the transfer of any existing  option grant
award in the manner specified by the Committee.

12.  Agreements
     ----------

     Options  granted  pursuant to the Plan shall be  evidenced  by stock option
agreements in such form as the Committee shall from time to time adopt.

13.  Adjustment of Number of Shares
     ------------------------------

     In the event a dividend  shall be  declared  upon the  Common  Stock of the
Company  payable in Shares (other than a stock  dividend  declared in lieu of an
ordinary cash  dividend),  the number of Shares then subject to any such option,
the maximum number of shares set forth in the second  sentence of Section 8, and
the number of Shares  reserved  for  issuance  pursuant  to the Plan but not yet
covered by an option,  shall be  adjusted  by adding to each Share the number of
Shares which would be  distributable  thereon if such Share had been outstanding
on the date fixed for  determining  the  stockholders  entitled to receive  such
stock dividend.  In the event the outstanding  Shares of the Common Stock of the
Company  shall be changed  into or exchanged  for a different  number or kind of
Shares of stock or other  securities  of the Company or of another  corporation,
whether through reorganization, recapitalization, stock split-up, combination of
Shares, merger or consolidation,  then there shall be substituted for each Share
reserved  for issuance  pursuant to the Plan,  but not yet covered by an option,
the maximum number of shares set forth in the second  sentence of Section 8, the
number of shares then subject to any such option,  the number and kind of Shares
of stock or other  securities  into which  each  outstanding  Share  shall be so
changed or for which  each such Share  shall be  exchanged.  In the event  there
shall be any change,  other than as  specified  above in this  paragraph  in the
number or kind of  outstanding  Shares or of any  stock or other  security  into
which such Common  Stock shall have been changed or for which it shall have been
exchanged,  then if the Committee  shall in its sole  discretion  determine that
such change  equitably  requires an  adjustment  in the number or kind of Shares
theretofore  reserved for issuance  pursuant to the Plan, but not yet covered by
an option,  the  maximum  number of shares set forth in the second  sentence  of
Section 8 and/or of the  Shares  then  subject  to an  option or  options,  such
adjustment shall be made by the Committee and shall be effective and binding for
all purposes of the Plan and of each stock option agreement. The option price in
each stock option  agreement for each Share or other  securities  substituted or
adjusted as provided for in this  paragraph  shall be determined by dividing the
option  price in such  agreement  for each Share prior to such  substitution  or
adjustment  by the number of Shares or the fraction of a share  substituted  for
such Share or to which such Share shall have been  adjusted.  No  adjustment  or
substitution  provided for in this  paragraph  shall  require the Company in any
stock option agreement to sell a fractional Share, and the total substitution or
adjustment  with  respect  to each  stock  option  agreement  shall  be  limited
accordingly.


                                       5


14.  Shares Available
     ----------------

     There shall be reserved,  for the purpose of the Plan, a total of 1,500,000
Shares  of  Common  Stock  (or the  number  and kind of Shares of stock or other
securities which, in accordance with Section 13 hereof, shall be substituted for
said Shares or to which said Shares shall be  adjusted).  Such Shares may be, in
whole or in part,  authorized  and unissued  Shares or issued Shares which shall
have been  reacquired  by the Company.  In the event that (i) an option  granted
under the option plan to any employee expires or is terminated unexercised as to
any Shares covered  thereby,  (ii) Shares are forfeited for any reason under the
Plan,  or (iii)  Shares are  tendered to exercise an option,  such Shares  shall
thereafter be available for the granting of options under the Plan.

15.  Expenses
     --------

     The expenses of administering the Plan shall be borne by the Company.

16.  Non-Exclusivity
     ---------------

     Neither  the  adoption  of the  Plan  by the  Board  of  Directors  nor the
submission of the Plan to the  stockholders of the Company for approval shall be
construed as creating any  limitations on the power of the Board of Directors to
adopt such  other  incentive  arrangements  as it may deem  desirable,  and such
arrangements may be either  generally  applicable or applicable only in specific
cases.

17.  Amendment
     ---------

     The Board of Directors,  without further approval of the stockholders,  may
from  time to time  amend  the  Plan in such  respects  as the  Board  may  deem
advisable;  provided,  however, that no amendment shall become effective without
prior approval of the  stockholders  which would (a) increase the maximum number
of Shares  which may be awarded,  or for which  options  may be granted,  in the
aggregate  under the Plan;  or (b) reduce the minimum  option price which may be
established  under the Plan.  No  amendment  shall,  without  the  Participant's
consent,  alter or impair  any of the  rights or  obligations  under any  option
theretofore granted to him under the Plan.
