         A member of the Board shall be deemed to be "disinterested"  only if he
or she, at the time of his or her appointment to the Committee and within the 12
preceding months,  was not eligible,  under this Plan or under any other plan of
the-Corporation  or an affiliate of the Corporation,  for the purchase of stock,
for the grant of rights or options to purchase  stock, or for the grant of stock
appreciation rights.

         5. ELIGIBILITY.

         (a) Eligible Classes.

         The Optionees  shall be such Employees (who may be officers or employee
directors) as the Committee may select,  subject to the terms and conditions set
forth below.

         (b) Ten-Percent Shareholders.

         An Employee who owns more than 10% of the total  combined  voting power
of  all  classes  of  outstanding  stock  of  the  Corporation  or  any  of  its
Subsidiaries shall not be eligible to receive an Incentive Stock Option,  unless
(i) the Exercise  Price of the Shares subject to such Option is at least 110% of
the Fair  Market  Value of such Shares on the date of grant and (ii) the term of
such Option does not exceed five years from the date of grant.

         (c) Attribution Rules.

         For purposes of (b) above, in determining  stockownership,  an Employee
shall be deemed to own the stock owned, directly or indirectly, by or for his or
her brothers,  sisters, spouse,  ancestors and lineal descendants.  Stock owned,
directly or indirectly,  by or for a corporation,  partnership,  estate or trust
shall be deemed to be owned proportionately by or for its shareholders, partners
or  beneficiaries.  Stock with  respect to which such  Employee  holds an option
shall not be counted.

         (d) Outstanding Stock.

         For purposes of (b) above,  "outstanding stock" shall include all stock
actually  issued and  outstanding  immediately  after the grant of the Incentive
Stock  Option to the  Optionee.  "Outstanding  stock"  shall not include  shares
authorized for issuance under outstanding options held by the Optionee or by any
other person.

                                       4




         6. STOCK.

         The  aggregate  number of Shares  which may be issued upon  exercise of
Options under the Plan shall not exceed 350,000. The number of Shares subject to
Options  outstanding  at any time shall not  exceed  the  number of Shares  then
remaining  available  for  issuance  under  the  Plan.  In the  event  that  any
outstanding Option for any reason expires or is terminated, the Shares allocable
to the unexercised  portion of such Option may again be made subject to Options.
The  limitation  established by this Section 6 shall be subject to adjustment in
the manner  provided  in Section 10 upon the  occurrence  of an event  specified
therein.

         7. TERMS AND CONDITIONS OF OPTIONS.

         (a) Stock Option Agreements.

         Options shall be evidenced by written  stock option  agreements in such
form as the Committee shall from time to time determine.  Such agreements  shall
comply with and be subject to the terms and conditions set forth below. However,
the provisions of all stock option  agreements  executed under the Plan need not
be identical.

         (b) Number of Shares.

         Each Option shall specify the number of Shares to which it pertains and
shall provide for the  adjustment of such number in accordance  with Section 10.
The Option  shall also  specify  whether it is an  Incentive  Stock  Option or a
Nonstatutory Stock Option.

         (c) Exercise Price.

         Each Option shall specify the Exercise Price.  The Exercise Price under
a Nonstatutory  Stock Option shall not be less than 85% of the Fair Market Value
on the date of grant.  The Exercise Price under any Incentive Stock Option shall
not be less than 100% of the Fair Market  Value on the date of grant and, in the
case of an Incentive  Stock Option  granted to an Optionee  described in Section
5(b), shall not be less than 110% of the Fair Market Value on the date of grant.

                                       5




         (d) Medium and Time of Payment.

         The Purchase  Price shall be payable in full in United  States  dollars
upon the exercise of the Option,  except that the Committee  may determine  that
all or part of the Purchase  Price can be paid (i) by the surrender of Shares in
good form for transfer, owned for 12 months or more by the person exercising the
Option  and having a Fair  Market  Value on the date of  exercise  equal to that
portion of the Purchase  Price which is being paid with  Shares,  or (ii) with a
full-recourse  promissory  note executed by the Optionee.  The interest rate and
other terms and  conditions of such note shall be as specified by the Committee;
provided, however, that such note shall have a term of not more than five years,
shall be  payable  in full  within 90 days  after the  Optionee  ceases to be an
Employee  and shall bear  interest  at a rate not less than the Test  Rate.  The
Committee  may  require  that  the  Optionee  pledge  his or her  Shares  to the
Corporation  for the purpose of securing the repayment of such note.  Payment in
the form of a promissory note shall be permissible  only if the person executing
such note then is an Employee.

         (e) Withholding Taxes.

         As a  condition  to the  exercise  of an Option or the  disposition  of
Shares acquired under the Plan, the Optionee shall make such arrangements as the
Committee  may  require  for the  satisfaction  of any  Federal,  state or local
withholding tax  obligations  that may arise in connection with such exercise or
disposition.

         (f) Term and Nontransferability of Options.

         Each option shall specify the date when all or any installment  thereof
is to become  exercisable.  The Option shall also specify its term,  which shall
not exceed 10 years from the dateof grant and, in the case of an Incentive Stock
Option granted to an Optionee  described in Section 5(b),  shall not exceed five
years from the date of grant.

         During the lifetime of the  Optionee,  the Option shall be  exercisable
only by the Optionee and shall not be assignable or  transferable.  In the event
of the Optionee's death, the Option shall not be transferable other than by will
or by the laws of descent and distribution.

         (g) Termination of Service (Except by Death).

         If an Optionee  ceases to be an Employee  for any reason other than his
or her death,  then the Optionee  shall have the right to exercise an Option (to
the extent not previously  exercised and not expired) at any time within 90 days
after the date when he or she ceases to be an  Employee,  but only to the extent
that,  on such date,  the  Optionee's  right to  exercise  then such  Option has
accrued  pursuant to the terms of the  applicable  stock option  agreement.  The
Committee, in the applicable stock option agreement,

                                       6




may replace such period of 90 days with any other period.

         For purposes of this Subsection (g), the Employee relationship shall be
deemed to continue while the Optionee is on military leave,  sick leave or other
bona fide leave of  absence  (to be  determined  in the sole  discretion  of the
Committee).  The foregoing  notwithstanding,  in the case of an Incentive  Stock
Option,  the Employee  relationship  shall not be deemed to continue  beyond the
90th day after the Optionee ceased active  employment as a common-law  employee,
unless  the  Optionee's  reemployment  rights  are  guaranteed  by statute or by
contract.

         (h) Death of Optionee.

         If an Optionee  dies while an Employee  and has not fully  exercised an
Option,  then such  Option  (to the  extent  not  previously  exercised  and not
expired)  may be  exercised  at any time within 12 months  after the  Optionee's
death by the executors or  administrators  of his or her estate or by any person
or persons who have acquired  such Option  directly from the Optionee by bequest
or  inheritance,  but only to the  extent  that,  at the date of the  Optionee's
death,  the Optionee's right to exercise such Option had accrued pursuant to the
terms of the applicable stock option agreement.

         If an Optionee  dies after the Employee  relationship  terminated,  but
within the period  during  which an Option could have been  exercised  under (g)
above, and has not fully exercised such Option,  then such Option (to the extent
not previously exercised and not expired) may be exercised at any time within 12
months after the Optionee's death by the executors or  administrators  of his or
her estate or by any person or persons who have  acquired  such Option  directly
from the Optionee by bequest or inheritance, but only to the extent that, at the
date of  termination  of the  Employee  relationship,  the  Optionee's  right to
exercise such Option had accrued  pursuant to the terms of the applicable  stock
option agreement.

         (i) Rights as a Shareholder.

         An Optionee, or a transferee of an Optionee,  shall have no rights as a
shareholder  with  respect to any Shares  covered by his or her Option until the
date of the issuance of a stock certificate for such Shares. No adjustment shall
be made for dividends (ordinary or extraordinary, whether in cash, securities or
other  property),  distributions  or other  rights for which the record  date is
prior to the date when such stock  certificate is issued,  except as provided in
Section 10.

                                       7




         (j) Modification, Extension and Renewal of Options.

         Within the limitations of the Plan, the Committee may modify, extend or
renew outstanding  Options or accept the cancellation of outstanding Options (to
the  extent  not  previously  exercised)  for the  granting  of new  Options  in
substitution  therefor.  The foregoing  notwithstanding,  no  modification of an
Option shall, without the consent of the Optionee, alter or impair any rights or
obligations under such Option.

         (k) Other Provisions.

         The stock option agreements  authorized under the Plan may contain such
other provisions not inconsistent with the terms of the Plan (including, without
limitation,  restrictions upon the exercise of the Option or the transferability
of Shares) as the Committee may deem advisable.

         8. LIMITATION ON ISO AWARDS.

         No Incentive  Stock Options  shall be granted to an Optionee  under the
Plan if the  aggregate  Fair  Market  Value of the Stock  subject  to his or her
Incentive  Stock Options which become  exercisable for the first time during any
one calendar year (under all plans of the Corporation, any parent corporation or
a Subsidiary)  would exceed  $100,000.  For purposes of this Section 8, the Fair
Market Value of a Share shall be  determined  as of the date when the  Incentive
Stock Option covering such Share is granted.

         9. TERM OF PLAN.

         Options  may be granted  pursuant  to the Plan until May 12,  1997,  or
until such earlier date as the Board may determine at its sole discretion.

         10. RECAPITALIZATIONS.

         Subject to any required  action by  stockholders,  the number of Shares
covered by the Plan as  provided  in Section 6, the number of Shares  covered by
each  outstanding  Option  and the  Exercise  Price  thereof  shall be  adjusted
proportionately  for any  increase or  decrease  in the number of issued  Shares
resulting  from a  subdivision  or  consolidation  of Shares or the payment of a
stock  dividend or any other increase or decrease in the number of issued Shares
effected without receipt of consideration by the Corporation.

         Subject to any required action by  stockholders,  if the Corporation is
the  surviving  corporation  in any merger or  consolidation,  each  outstanding
Option shall pertain to the securities to which a holder of the number of Shares
subject to the Option would have been entitled.  A dissolution or liquidation of
the Corporation or a merger or

                                       8




consolidation  in which the Corporation is not the surviving  corporation  shall
cause each  outstanding  Option to terminate,  unless the agreement of merger or
consolidation  provides for the assumption thereof by the surviving corporation;
provided,  however,  that each Optionee  shall have the right to exercise his or
her  Options  in  full  immediately  prior  to the  date  of  such  dissolution,
liquidation,  merger or consolidation,  but only to the extent that such Options
have not previously been exercised,  have not expired and are not assumed by the
surviving corporation.

         To the extent that the  foregoing  adjustments  relate to securities of
the  Corporation,  such  adjustments  shall  be  made  by the  Committee,  whose
determination shall be conclusive and binding on all persons.

         Except as expressly  provided in this  Section 10, the  Optionee  shall
have no rights by reason of any subdivision or  consolidation of shares of stock
of any  class,  the  payment  of any stock  dividend  or any other  increase  or
decrease  in the  number  of  shares  of stock of any  class or by reason of any
dissolution, liquidation, merger or consolidation or spin-off of assets or stock
of another  corporation,  and any issue by the Corporation of shares of stock of
any class, or securities  convertible  into shares of stock of any class,  shall
not affect,  and no adjustment by reason  thereof shall be made with respect to,
the number or Exercise Price of Shares subject to an Option.

         The grant of an Option pursuant to the Plan shall not affect in any way
the right or power of the  Corporation to make  adjustments,  reclassifications,
reorganizations  or changes of its  capital or business  structure,  to merge or
consolidate or to dissolve,  liquidate,  sell or transfer all or any part of its
business or assets.

         11. SECURITIES LAW REQUIREMENTS.

         (a) Legality of Issuance.

         No Shares  shall be issued upon the  exercise of any Option  unless and
until the Corporation has determined that (i) it and the Optionee have taken all
actions  required to register the Shares under the  Securities  Act of 1933,  as
amended  (the  "Act"),   or  to  perfect  an  exemption  from  the  registration
requirements  thereof;  (ii) any  applicable  listing  requirement  of any stock
exchange  on which  Stock is  listed  has been  satisfied;  and  (iii) any other
applicable provision of state or Federal law has been satisfied.

         (b) Restrictions on Transfer; Representations of Optionee.

         Regardless  of whether the  offering  and sale of Shares under the Plan
have been  registered  under the Act or have been  registered or qualified under
the securities laws of any state, the Corporation may impose  restrictions  upon
the sale,  pledge or other  transfer of such Shares  (including the placement of
appropriate   legends  on  stock  certificates)  if,  in  the  judgment  of  the
Corporation  and its counsel,  such  restrictions  are necessary or desirable in
order to achieve  compliance with the provisions of the Act, the

                                       9




securities  laws of any state or any other  law.  In the event  that the sale of
Shares  under  the Plan is not  registered  under  the Act but an  exemption  is
available which requires an investment  representation or other  representation,
each Optionee shall be required to represent that such Shares are being acquired
for investment,  and not with a view to the sale or distribution thereof, and to
make such other  representations  as are deemed  necessary or appropriate by the
Corporation and its counsel. Stock certificates evidencing Shares acquired under
the Plan  pursuant  to an  unregistered  transaction  shall bear an  appropriate
restrictive legend.

         Any determination by the Corporation and its counsel in connection with
any of the matters set forth in this Section 11 shall be conclusive  and binding
on all persons.

         (c) Registration or Qualification of Securities.

         The Corporation may, but shall not be obligated to, register or qualify
the sale of Shares under the Act or any other  applicable  law. The  Corporation
shall not be obligated to take any affirmative action in order to cause the sale
of Shares under the Plan to comply with any law.

         (d) Removal of Legends.

         If, in the  opinion  of the  Corporation  and its  counsel,  any legend
placed on a stock  certificate  representing  Shares issued under the Plan is no
longer required,  the holder of such  certificate  shall be entitled to exchange
such  certificate for a certificate  representing  the same number of Shares but
lacking such legend.

         12. AMENDMENT OF THE PLAN.

         The Board may from time to time, with respect to any Shares at the time
not subject to Options, suspend or discontinue the Plan or revise or amend it in
any respect  whatsoever  except that,  without the approval of the Corporation's
shareholders, no such revision or amendment shall:

         (a)      Increase the number of Shares  subject to the Plan,  except as
                  provided in Section 10;

         (b)      Materially change the designation in Section 5 with respect to
                  the class of  Employees  eligible to receive  Incentive  Stock
                  Options; or

         (c)      Amend this Section 12 to defeat its purpose.

                                       10




         13.APPLICATION OF FUNDS.

         The  proceeds  received  by the  Corporation  from  the  sale of  Stock
pursuant  to the  exercise  of an  Option  will be used  for  general  corporate
purposes.

         14. APPROVAL OF SHAREHOLDERS.

         The  adoption  of the Plan and any  amendment  described  in Section 12
shall be  subject  to  approval  by the  affirmative  vote of the  holders  of a
majority of the outstanding shares of the Corporation entitled to vote or by the
unanimous  written  consent  of all  holders  of the  outstanding  shares of the
Corporation  entitled  to vote.  In the event that the Plan is not  approved  by
stockholders   within  12  months  after  adoption  by  the  Board,  any  Option
theretofore granted shall be null and void.

         15. EXECUTION.

         To record the  adoption of the Plan by the Board,  effective  as of May
13,  1987,  the  Corporation  has caused its  authorized  officers  to affix the
corporate name hereto.
