                                           -----
of One Million, Two Hundred Fifty Thousand Dollars ($1,250,000) (the "Principal
                                                                      ---------
Amount") on the termination of Maker's employment with Payee (the "Maturity
------                                                             --------
Date") as more fully described in Section 6.2.
----

     1.   Payment Provisions.  Maker covenants that so long as any amount
          ------------------
hereunder is outstanding:

          1.1.  Maturity.  Upon the occurrence of the Maturity Date, or on any
                --------
     accelerated maturity hereof, Maker will pay the entire principal amount of
     this Note then outstanding, together with all accrued and unpaid interest
     thereon.

          1.2.  Interest.  Interest calculated daily on the basis of a 365-day
                --------
     year on the entire Principal Amount from time to time unpaid through and
     including the maturity hereof shall accrue at a rate per annum equal to
     eight percent (8.0%) after the first anniversary of the date hereof. No
     interest shall accrue prior to the first anniversary hereof. Interest after
     maturity shall be payable at a rate of one percent (1%) per annum in excess
     of the rate payable hereunder prior to maturity. In no event shall the rate
     of interest hereunder exceed the maximum interest rate permitted by
     applicable law.

          1.3.  Voluntary Prepayments.  Maker may at any time or from time to
                ---------------------

     interest accrued on the prepaid amount.

          1.4.  Place of Payments.  Payment shall be made in lawful money of the
                -----------------

     writing to Maker.

     2.   Remedy.  If a default shall have occurred and be continuing, Payee
          ------
shall thereafter have the right and remedy (to the extent permitted by
applicable law), to demand, sue for or collect from Maker up to the entire
Principal Amount plus all accrued and unpaid interest thereon, such right and
remedy being exclusive.

     3.   Marshaling.  Payee shall not be required to marshal any present or
          ----------
future security for (including but not limited to this Promissory Note), or
other assurances of payment of, the amounts due hereunder, or to resort to such
security or other assurances of payment in any particular order. All of Payee's
rights hereunder and in respect of such security and other assurances of payment
shall be cumulative and in addition to all other rights, however existing or
arising. To the extent that he lawfully may, Maker hereby agrees that he will
not invoke any law relating to the marshaling of collateral that might cause
delay in or impede the enforcement of Payee's rights under this

Promissory Note, and to the extent that he lawfully may, Maker hereby
irrevocably waives the benefits of all such laws.

     4.   Maker's Obligations Not Affected.  The obligations of Maker hereunder
          --------------------------------
shall remain in full force and effect without regard to and shall not be
impaired b y (a) any exercise or nonexercise, or any waiver, by Payee of any
right, remedy, power or privilege under or in respect of any of such obligations

Note, or (c) the taking of additional security for, or any other assurances of
payment of, any of such obligations or the release or discharge or termination
of any security or other assurances of payment or performance for any of such
obligations; whether or not Maker shall have notice or knowledge of any of the
foregoing.

     5.   Further Assurances. Maker will do all such acts, and will furnish to
          ------------------
Payee all such financing statements, certificates, legal opinions and other
documents and will obtain all such governmental consents and corporate approvals
and will do or cause to be done all such other things as Payee may reasonably
request from time to time in order to give full effect to this Promissory Note
and to secure the rights of Payee hereunder, all without any cost or expense to
Payee. If Payee so elects, a photocopy of this Promissory Note may at any time
and from time to time be filed by Payee as a financing statement in any
recording office in any jurisdiction.
