subsequent employment.

--------------------------------------------------------------------------------

7.
Section 280G Matters. If the benefits described in Section 3 or 4 herein, as
applicable, would otherwise constitute a parachute payment under Section 280G of
the Internal Revenue Code of 1986, as amended (the “Code”), and but for this
Section would be subject to the excise tax imposed by Section 4999 of the Code
(the “Excise Tax”), Executive shall either:

a.
pay the Excise Tax, or

b.
have the benefits reduced to such lesser extent as would result in no portion of
such benefits being subject to the Excise Tax, whichever of the foregoing
amounts, taking into account the applicable federal, state and local income
taxes and the Excise Tax, results in the receipt by Executive on an after-tax
basis, of the greatest amount of benefits, notwithstanding that all or some
portion of such benefits may be taxable under Section 4999 of the Code.

Unless Company and Executive otherwise agree in writing, any determination
required under this Section shall be made in writing by Company’s independent
public accountants (“Accountants”), whose determination shall be conclusive and
binding upon Executive and Company for all purposes. For purposes of making the
calculations required by this Section, Accountants may make reasonable
assumptions and approximations concerning applicable taxes and may rely on
reasonable, good faith interpretations concerning the application of Section
280G and 4999 of the Code. Company and Executive shall furnish to Accountants
such information and documents as Accountants may reasonably request in order to
make a determination under this Section. Company shall bear all costs
Accountants may reasonably incur in connection with any calculations
contemplated by this Section.
8.
General Release. All compensation and benefits under Section 3 or 4 herein, as
applicable, are in consideration for Executive’s execution of the General
Release of all known and unknown claims that Executive may then have against
Company and its agents, a form of which is available from Company. If Executive
does not properly execute such General Release, the parties expressly
acknowledge and agree that Executive will not be entitled to any of the benefits
provided under Section 3 or 4 herein, as applicable.

9.
Employment Status. Nothing in this Agreement shall be deemed to constitute a
contract for employment for any specific period of time. The parties expressly
acknowledge and agree that the undersigned's employment with Company shall
continue to be “at will”.
