    5.   Special Acceleration Event.
         ---------------------------

         A.  In the event the Maker sells or otherwise transfers for value one
or more shares of the Corporation's common stock serving as collateral for this
Note, then the unpaid portion of the principal balance of this Note attributable
to the purchase price of those shares and the associated taxes incurred in
connection with their purchase (as such taxes are pro-rated over all the shares
of the Corporation's common stock serving as collateral for this Note) shall
become immediately due and payable, together with all accrued and unpaid
interest on such principal portion, and shall be paid directly out of the
proceeds of such sale or transfer.

         B.  Should the Corporation be acquired (whether by merger or
acquisition of all or substantially all of the Corporation's assets or
outstanding voting stock) for consideration payable in cash or freely-tradable
securities, then the unpaid portion of the principal balance of this Note
attributable to any shares of the Corporation's common stock serving as
collateral for this Note which are vested at the time of such acquisition,
including any such shares which vest as a result of such acquisition, shall
become immediately due and payable, together with all accrued and unpaid
interest on such principal portion, upon the expiration of the ninety (90)
period following the effective of such acquisition; provided, however, that if
the Pooling of Interest Method, as described in Accounting Principles Board
Opinion No. 16, is used to account for the acquisition for financial reporting
purposes, such acceleration shall not occur at any time prior to the end of the
sixty (60)-day period immediately following the end of the applicable
restriction period required under Accounting Series Release Numbers 130 and 135.

     6.  Employment.  For purposes of applying the provisions of this Note, the
         ----------
Maker shall be considered to remain in the Corporation's employ for so long as
the Maker renders services as a full-time employee of the Corporation, any
successor entity or one or more of the Corporation's fifty percent (50%)-or-more
owned (directly or indirectly) subsidiaries.

     7.  Security.  The proceeds of the loan evidenced by this Note shall be
         --------
applied solely to the payment of the purchase price of 45,000 shares of the
Corporation's common stock and the associated taxes incurred in connection with
the purchase of such shares, and payment of this Note shall be secured by a
pledge of those shares with the Corporation pursuant to the Stock Pledge
Agreement to be executed this date by the Maker. The Maker, however, shall
remain personally liable for payment of this Note and assets of the Maker, in
addition to the collateral under the Stock Pledge Agreement, may be applied to
the satisfaction of the Maker's obligations hereunder.

     8.  Collection.  If action is instituted to collect this Note, the
         ----------
Corporation shall provide prior written notice to the Maker of its intent to
pursue such legal action to collect this Note and Maker promises to pay all
costs and expenses (including reasonable attorney fees) incurred in connection
with such action.

limited to its express terms. No delay by the Corporation in acting with respect
to the terms of this Note or the Stock Pledge Agreement shall constitute a
waiver of any breach, default, or failure of a condition under this Note, the
Stock Pledge Agreement or the obligations secured thereby.

    10.  Conflicting Agreements.  In the event of any inconsistencies between
         ----------------------
