     Disability or Retirement  (termination  on or after age 65), or if Optionee
     terminates employment after age 55, the following shall apply:

          (a)  Termination  Due To Death.  In the event the Optionee  dies while
               actively employed,  all vested Options at the date of death shall
               remain  exercisable  at any time prior to the  expiration  of the
               Exercise  Term by (A)  such  person(s)  that  have  acquired  the
               Optionee's  rights  under such  Options by will or by the laws of
               descent and  distribution,  or (B) if no such person described in

               Optionee  is  terminated  by reason  of  Disability,  all  vested
               Options  as of the date the  Committee  determines  the  Optionee
               terminated  for Disability  shall remain  exercisable at any time
               prior to the  expiration of the Exercise  Term.  All Options that
               are not vested as of the date of termination for Disability shall
               be immediately forfeited.

          (c)  Termination  by  Retirement.  In the event the  employment of the
               Optionee is terminated by reason of  Retirement,  the  Optionee's
               Options shall  continue to vest in  accordance  with the original
               schedule  (just as if the  Optionee had  remained  employed)  and
               shall remain  exercisable  at any time prior to the expiration of
               the Exercise  Term.  In the event of the  Optionee's  death after
               Retirement, the Options shall continue to vest and be exercisable
               in  accordance  with this  subsection  (c) as if the Optionee had
               lived  and  the  Options  shall  be  exercisable  by the  persons
               described in (a) above.

          (d)  Termination  After  Attaining Age 55. If the Optionee  terminates
               employment  (other than as a result of death or Disability) after
               attaining  age 55 but  prior  to age  65,  unless  the  Committee
               determines  otherwise  at  the  time  of  such  termination,  the
               Optionee's  Options shall continue to vest in accordance with the
               original schedule (just as if the Optionee had remained employed)
               and shall remain  exercisable at any time prior to the expiration
               of the Exercise Term. In the event of the Optionee's  death after
               Retirement, the Options shall continue to vest and be exercisable
               in  accordance  with this  subsection  (d) as if the Optionee had
               lived  and  the  Options  shall  be  exercisable  by the  persons
               described in (a) above.

     7. Effect of Change in Control.

          7.1  Notwithstanding  anything  contained  to  the  contrary  in  this
     Agreement, in the event of a Change in Control, (i) the Option shall become
     immediately and fully exercisable,  and (ii) the Optionee will be permitted
     to surrender for  cancellation  within sixty (60) days after such Change in
     Control,  the  Option or any  portion  of the  Option to the extent not yet
     exercised, and the Optionee shall be entitled to receive immediately a cash
     payment in an amount  equal to the  excess,  if any, of (A) the Fair Market
     Value,  at the time of  surrender,  of the Shares  subject to the Option or
     portion thereof surrendered, over (B) the aggregate purchase price for such
     Shares under the Option; provided,  however, that if the Option was granted
     within six (6) months  prior to the Change in Control and the  Optionee may
     be subject to  liability  under  Section  16(b) of the  Exchange  Act,  the
     Optionee  shall be entitled to surrender the Option,  or any portion of the
     Option,  for  cancellation  during the sixty (60) day period  following the
     expiration  of six (6) months from the Grant Date and to receive the amount
     described above with respect to such surrender for cancellation.

          7.2 If the  employment  of the Optionee is  terminated  within two (2)
     years  following a Change in Control,  all vested Options shall continue to
     be  exercisable  at any time within  three (3) years after the date of such
     termination of employment, but in no event after expiration of the Exercise
     Term.

     8. Nontransferability.

          The Option shall not be transferable other than by will or by the laws
     of descent  and  distribution.  During the  lifetime of the  Optionee,  the
     Option shall be exercisable only by the Optionee.

     9. No Right to Continued Employment.

          Nothing  in  this  Agreement  or the  Plan  shall  be  interpreted  or
     construed to confer upon the Optionee any right with respect to continuance
     of employment by the Company or a Subsidiary,  nor shall this  Agreement or
     the Plan interfere in any way with the right of the Company or a Subsidiary
     to terminate the Optionee's employment at any time.

     10. Adjustments.

          In the event of a Change in  Capitalization,  the  Committee  may make
     appropriate adjustments to the number and class of Shares or other stock or
     securities  subject to the Option and the purchase price for such Shares or
     other stock or  securities.  The  Committee's  adjustment  shall be made in
     accordance  with the  provisions  of  Section  11 of the Plan and  shall be
     effective and final,  binding and  conclusive  for all purposes of the Plan
     and this Agreement.

     11. Terminating Events.

          Subject  to  Section  7  hereof,  upon the  effective  date of (i) the
     liquidation or dissolution of the Company or (ii) a merger or consolidation
     of the Company (a  "Transaction"),  the Option shall  continue in effect in
     accordance  with its terms and the Optionee shall be entitled to receive in
     respect of all Shares  subject to the Option,  upon exercise of the Option,
     the same  number and kind of stock,  securities,  cash,  property  or other
     consideration  that each  holder of Shares was  entitled  to receive in the
     Transaction.

     12. Withholding of Taxes and Notice of Disposition.

          12.1 The Company shall have the right to deduct from any  distribution
     of cash to the  Optionee an amount  equal to the  federal,  state and local
     income  taxes and other  amounts as may be  required  by law to be withheld
     (the  "Withholding  Taxes") with respect to the Option.  If the Optionee is
     entitled to receive Shares upon exercise of the Option,  the Optionee shall
     pay the  Withholding  Taxes (if any) to the  Company  in cash  prior to the
     issuance of such Shares.  In  satisfaction of the  Withholding  Taxes,  the
     Optionee may make a written  election  (the "Tax  Election"),  which may be
     accepted or rejected in the discretion of the Committee, to have withheld a
     portion of the Shares  issuable to him or her upon  exercise of the Option,
     having an  aggregate  Fair  Market  Value equal to the  withholding  Taxes,
     provided  that,  if the Optionee may be subject to liability  under Section
     16(b) of the Exchange Act, the election  must comply with the  requirements
     applicable to Share transactions by such Optionees.

     Section 424(c) of the Code and regulations promulgated  thereunder,  of any
     Share or Shares issued to him pursuant to his exercise of the Option within
     the two-year  period  commencing  on the day after the Grant Date or within
     the  one-year  period  commencing  on the day after the date of transfer of
     such  Share or  Shares  to the  Optionee  pursuant  to such  exercise,  the
     Optionee  shall,  within  ten (10)  days of such  disposition,  notify  the
     Company  thereof,  by  delivery  of  written  notice to the  Company at its
     principal  executive  office,  and  immediately  deliver to the Company the
     amount of Withholding Taxes.
