options granted subsequent to commencement of employment) (a) at September 19,
2003, or (b) on an Acceleration Event (as defined in that certain Incentive
Stock Option Agreement dated as of the date hereof), is not worth One Million

          (g) Change in Control. For purposes of this Agreement, "Change in
              -----------------
Control" shall be deemed to occur if (i) any "person" as that term is used in
Sections 13 and 14(d)(2) of the Exchange Act), other than Steven E. Bernstein,
is or becomes the beneficial owner (as that term is used in Section 13(d) of the
Exchange Act), directly or indirectly, of twenty-five percent (25%) or more of
the voting stock; or (ii) during any period of two consecutive years,
individuals who at the beginning of such period constitute the Board ceases for
any reason to constitute at least a majority thereof, unless the election or the

consolidation or corporate reorganization in which the owners of the Company's
capital stock entitled to vote in the election of directors ("Voting Stock")

     7. COMPENSATION UPON TERMINATION
        -----------------------------

          (a) If Hunt's employment is terminated for any reason pursuant to
Section 6(d) or Section 6(f) hereof, the Company shall be obligated to pay to
Hunt a severance payment in an amount equal to the Base Salary plus the then
current minimum cash bonus potential, such payment to be made in a lump sum on
or before the fifth day following the Date of Termination; provided, however,
                                                           --------  -------
that if the lump sum severance payment under this Section 7(a), either alone or
together with other payments which Hunt has the right to receive from the
Company, would constitute a "parachute payment" (as defined in Section 280G of
the Internal Revenue Code of 1986, as amended (the "Code")), such lump sum
severance payment shall be reduced to the largest amount as will result in no
portion of the lump sum severance payment under this Section 7(a) being subject
to the excise tax imposed by Section 4999 of the Code. The determination of any
reduction in the lump sum severance payment under this Section 7(a) pursuant to
the foregoing provision shall be made by independent counsel to the Company in
consultation with the independent certified public accounts of the Company. In
addition to the foregoing, the Company shall be obligated to pay to Hunt all
amounts accrued hereunder and otherwise, through and including the Date of -
Termination, whether such amounts were payable prior to the Date of Termination
or thereafter, and Hunt shall be entitled to receive any extension of benefits
beyond the Date of Termination, provided that (i) such benefits were received by
Hunt prior to the Date of Termination and (ii) such extension is customarily
offered by the Company to its employees or is otherwise required by applicable
law.

          (b) If Hunt's employment is terminated pursuant to Sections 6(a),
6(b), 6(c) or 6(e) hereof, on and after the Date of Termination the Company
shall no longer be obligated to pay Hunt any amounts payable hereunder for such
period, whether in the form of Base Salary or otherwise, and Hunt shall have no
right to compensation or other benefits hereunder for any such period.
Notwithstanding the foregoing, the Company shall be obligated to pay to Hunt all
amounts accrued hereunder and otherwise, through and - including the Date of
Termination, whether such amounts were payable prior to the Date of Termination
or thereafter, and Hunt shall be entitled to receive any extension of benefits
beyond the Date of Termination, provided that (i) such benefits were received by
Hunt prior to the Date of Termination and (ii) such extension is customarily
offered by the Company to its employees or is otherwise required by applicable
law.

          (c) Notwithstanding the foregoing or anything contained herein to the
contrary, in no event shall the total amount of payments made under this Section
7 of this Agreement on account of termination under Section 6(f)(v) hereof
exceed three times the "base amount" minus one dollar. "Base Amount" means the
average annualized compensation income from the Company includible in Hunt's
gross income for Federal income tax purposes over the five-year period (or such
lesser period as Hunt shall have been employed) preceding the year in which
Hunt's employment is terminated. This paragraph, and the language therein, shall
be interpreted consistently with Section 280G of the Internal Revenue Code of
1986, as amended, and any regulations thereunder.

          (d) The foregoing provisions shall be in addition to, and not in
limitation of, Hunt's rights to exercise stock options granted to him or sell
any restricted stock issued to him and Hunt's rights under Section 4(f) in
connection therewith.
