     a.   Completion of Retention period and [ ] Win.
          -------------------------------------------
          Subject to Section 3(d), if the Executive remains employed through the

     b.   Completion of Retention Period and [ ] Loss.
          --------------------------------------------
          If the Executive remains employed through the completion of the
          Retention Period and the Corporation does not win the [ ] competition,
          he will receive a lump-sum retention bonus equal to the amount
          calculated in Section 3(a), reduced by one-third (1/3).  The retention

          retention bonus equal to the amount calculated under Section 3(a),
          reduced by one-third (1/3) and further reduced on a pro-rata basis for
          each day by which the Executive's death disability or resignation date
          precedes December 31, 2001. The retention bonus shall be paid as soon
          as practicable following the Executive's death, disability or
          resignation.



     d.   Delay in [ ] Award.  If the [ ] award decision is delayed beyond
          ---------------------

          shall be paid to the Executive as soon as practicable following
          completion of the Retention Period.  If the Company wins the [  ]
          competition, an additional amount equal to the difference between the
          amount paid pursuant to the preceding sentence and the amount payable
          under Section 3(a) shall be paid as soon as practicable following the
          award decision.  Notwithstanding the foregoing, the Compensation
          Committee of the Company's Board of Directors may, in its sole
          discretion, elect to pay such additional amount prior to the receipt
          of the award decision.  Any such payment will be final and not subject
          to repayment to the Company by the Executive if the Company does not
          win the [ ] competition.

 
     e.   Termination By Corporation For Substantial and Serious Cause.  If,
          ------------------------------------------------------------      
          prior to the completion of the Retention Period, the Executive's
          employment is terminated by the Corporation for Substantial and
          Serious Cause, no retention bonus will be payable and no further
          obligation under this Agreement shall exist on the part of the
          Corporation (or its Affiliates) to the Executive.

     f.   Termination By Corporation For Other than Substantial and Serious
          -----------------------------------------------------------------
          Cause or Resignation by Executive For Good Cause. If, prior to the
          ------------------------------------------------                  
          completion of the Retention Period, the Executive's employment is
          terminated by the Corporation for any reason other than Substantial
          and Serious Cause or the Executive resigns for Good Cause, the
          Corporation shall pay to the Executive a retention bonus equal to the
          retention bonus payable under Section 3a as soon as practicable
          following the Executive's termination of employment.  Additionally,
          the Corporation may unilaterally terminate this Agreement at any time,
          in which case the Corporation shall pay to the Executive a retention
          bonus equal to the retention bonus payable under Section 3a as soon as
