waiting period with respect to such benefits effective March 1, 1996.  In
addition, the Company agrees to reimburse employee up to $10,000 for Internal
Revenue Service defined moving expenses upon delivery of invoices reflecting

     2.3  Bonuses.  Such bonuses as are approved by the unanimous affirmative
          -------                                                            
vote of the entire membership of the Compensation Committee ("Compensation
Committee") of the Board of Directors of the Company ("Committee Approval");
provided

 
that the potential bonus amount for 1996 is hereby established as follows:  for
calendar year 1996, an Incentive Bonus (the "1996 Incentive Bonus") will be paid
if the applicable Financial Target for 1996 (as set forth below) shall be
attained or exceeded.  The amount of the 1996 Incentive Bonus a maximum of 40%
of Salary; 20% to be paid if the Financial Target for 1996 is achieved and
another 20% if certain goals are attained as determined by the President and
Chief Executive Officer of Company.  The Financial Target for 1996 shall be
earnings per share of $0.81. In calculating whether Employer has attained the
Financial Target for 1996 the amount of the 1996 Incentive Bonus shall be
included and items of extraordinary gain and loss shall be excluded.  Nothing in
this Agreement shall prevent the Compensation Committee from awarding an
Incentive Bonus for 1996 if the Financial Target is not met or from awarding an
Incentive Bonus in excess of 40% of Salary for 1996.  Incentive Bonuses in
calendar years after 1996 need not be determined in a similar manner as the 1996
Incentive Bonus; provided however, that in the event that the Financial Target
and/or certain goals applicable to each calendar year after 1996 is met, the
percentage applicable to that year shall not be less than the percentage
applicable to the immediately preceding year.  Such bonus, if any, as determined
in accordance with the provisions of this Section 2.3 shall be paid no later
than fifteen (15) days following the Compensation Committee's review and
approval that such Financial Targets have been attained.

     2.4  Acceleration of Retirement Benefits.  In the event Company terminates
          -----------------------------------                                  
this Agreement for any reason other than under Section 3.2 hereof or if
Employee's employment terminates by reason of death or disability as described
in Section 3.3 hereof, then in addition to amounts otherwise payable to
Employee, Company shall pay Employee, within thirty (30) days of the effective
date of termination, an amount equal to the portion of Company's contributions
for the benefit of Employee under Company's Savings Plan, or any other qualified
retirement plan of Company then in effect, that has not vested as of the date of
Employee's termination, if any, plus an additional amount sufficient to satisfy
Employee's federal or state income tax liability with respect to the foregoing
payment and any additional amount payable pursuant to this Section 2.4, it being
Company's intention that Employee's net after tax position be identical to that
which would have been obtained had  Employee not been subject to any federal or
state income tax liabilities with respect to payments made under this Section
2.4.

     2.5  Acceleration of Exercisability of Stock Options.  In the event
          -----------------------------------------------               
Employee is terminated for any reason other than under Section 3.2 hereof, or if
Employee's employment terminates by reason of death or disability as described
in Section 3.3 hereof, or in the event of a Constructive Discharge, as defined
below, then all unexer  cised options granted to Employee under Company's stock
option plans which would otherwise have vested within twelve (12) months from
the date of Employee's termination or which would otherwise have vested during
the full Term of this Agreement, whichever is greater, shall be deemed fully
vested and exercisable immediately upon Employee's termination.  In determining
which options shall become immediately exercisable hereunder, the then
unexercisable options under each grant of options to Employee shall

                                      -2-

 
become exercisable.  The foregoing benefit shall be in addition to, and not in
lieu of, any similar benefit contained in the Executive Severance Agreement
between Company and Employee, dated as of March 1, 1996 (the "Executive
Severance Agreement").  For purposes of this Agreement, the term "Constructive
Discharge" means a termination of Employee's employment by Employee due to a
failure of Company or its successors, without the prior written consent of
Employee, to fulfill Company's obligations under this Agreement in any material
respect, including any material change by Company in the functions, duties, or

ranking, level, dignity, responsibility, importance or scope of such position.
