action or omission was in the best interest of the Company.

                           For purposes of Section 5.1 of this Agreement,

<PAGE>



Board  of  Directors,  Executive  fails  to  render  services  of the  character
contemplated  hereby because of illness or other  incapacity for a period of six
(6) consecutive  months,  or for shorter periods  aggregating  more than six (6)
months  in any  consecutive  twelve  (12)  months,  the Board of  Directors  may
determine  that  Executive  had become  disabled and may elect to terminate  his
employment  hereunder,  effective as of the date of such  determination.  In the
event  of  Executive's  death  during  the term  hereof,  this  Agreement  shall
terminate forthwith.

hereunder is  terminated  under  Section 5.2, the Company shall pay Executive as
severance pay,  subject to  appropriate  deductions,  one-twelfth  (1/12) of his

termination  (hereinafter  "Monthly  Severance  Payment") during the period (the
"Severance  Period") ending on the earlier of (I) the date Executive obtains new
employment, either directly or indirectly, at an annual compensation in whatever
form of not less than the annual  Base  Salary  then in effect or (ii) three (3)
months from the date of the Termination Notice;  provided,  however, that should
Executive obtain new employment,  directly or indirectly  (through a corporation
or  other  entity  of which  Executive  or any  family  member  is an  employee,
shareholder, etc.), at an annual compensation less than the Base Salary provided
hereunder,  each Monthly Severance  Payment after such new employment  commences
shall be reduced by one-twelfth  (1/12) of Executive's  annual salary under such
new employment; and provided further, that Executive shall make available to the
Company,  any and all documents  pertaining to  Executive's  annual salary under
such new employment,  including,  without  limitation,  pay stubs, W-2's and the
appropriate  portions of any income tax  returns,  that  Company may  reasonably
request  in order to make  such  adjustments.  On the first  anniversary  of the
Commencement  Date, the Severance  Period shall be modified to be the earlier of
(I) the date Executive obtains new employment, either directly or indirectly, at
an annual  compensation in whatever form of not less than the annual Base Salary
then in effect  consistent  with the  foregoing  or (ii) six (6) months from the
date of the Termination  Notice. In the event that Executive's  employment shall
be terminated  pursuant to Sections 5.2 or 5.6 in  connection  with or resulting
from a sale of all or substantially all of the Company's assets or equity,  then
the Severance  Period shall be 12 months without regard to any other  employment
or compensation which Executive might secure from a third party.

                           5.5      Voluntary Termination.   If Executive 
voluntarily  terminates  his  employment  hereunder  other than as  provided  in
Section 5.6, he shall (i) give three (3) months  written notice and (ii) be paid
Base  Salary  through  the  date of his  termination  and  shall  receive  other
compensation  and benefits,  if any, as provided under the Company's  applicable
plans and programs.

Employment.  "Certain changes affecting  Executive's  employment" shall mean any
material  diminution in benefits or  employment  conditions as a result of which

Executive,  without his consent, any portion of his Base Salary or other amounts
due to Executive  under  Section 4 within ten (10) days of the date such payment
is due;

                                    5.6.2  the Company's failure to continue in 
effect or continue  Executive's  participation in any compensation plan which is
material  to his total  compensation  or its  failure to continue to provide him
with benefits substantially similar to those provided to all senior executives;

                                    5.6.3  the shifting of Executive's principal
