                                   SCHEDULE A


Incentive Compensation.
---------------------- 

          (a)  The Bonus shall be paid as a percent of Base Salary (as defined
in Section 5(a) of the Employment Agreement), based upon the achievements of
Target EBITDA, as provided in accordance with the following table:

<TABLE>
<CAPTION>
          TARGET EBITDA                               BONUS
          -------------                               -----
------------------------------------    -------------------------------------
<S>                                             <C>
                90%                                     20%
------------------------------------    -------------------------------------
                95%                                     40%
------------------------------------    -------------------------------------
               100%                                     60%
------------------------------------    -------------------------------------
               105%                                     90%
------------------------------------    -------------------------------------
               110%                                    120%
------------------------------------    -------------------------------------
</TABLE>

In accordance with the above table, if EBITDA achieved for any calendar year
exceeds 90% Target EBITDA, but is less than 100% Target EBITDA, the Bonus shall
be such percentage of Base Salary between 20% and 60%, calculated on a straight-
line basis, as corresponds to the relative achievement of EBITDA, with 20%
corresponding to 90% Target EBITDA and 60% corresponding to 100% Target EBITDA.
If EBITDA achieved for any calendar year exceeds 100% Target EBITDA, but is less
than 110% Target EBITDA, the Bonus shall be such percentage of Base Salary
between 60% and 120%, calculated on a straight-line basis, as corresponds to the
relative achievement of EBITDA, with 60% corresponding to 100% Target EBITDA and
120% corresponding to 110% Target EBITDA.  Notwithstanding the foregoing, if
greater than 110% Target EBITDA is achieved, the Board shall award an additional
Bonus beyond the formula Bonus provided above, in an amount that it shall
determine in its sole discretion.

          (b) Target EBITDA shall be established annually by the Board, or, at
the discretion of the Board, by the Compensation Committee and in either event,
with the concurrence of Executive as to the amount of Target EBITDA thereby
established.  In the event of an acquisition, disposition or other similar
extraordinary corporate event which would significantly alter the Target EBITDA
established for that year, the parties shall negotiate in good faith to set new
levels of Target EBITDA.
