PERQUISITES:
|-- |  | -------------------------



| | 1. |  | Medical and Other Insurance Coverage:The Corporation shall
provide such medical and other insurance coverage to the Executive
to the extent and on the terms that such benefits are made available
to other similarly situated employees. This provision does not
alter the Corporations right to modify or eliminate any employee
benefit plan from time to time and does not guarantee the
continuation of any kind or level of benefit or perquisite.
| | -- |  | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
|
| | 2. |  | Paid Personal Leave:The Executive shall receive vacation, sick and
personal holiday leave pursuant to the Corporations Paid Personal Leave Policy
(PPL) under the schedule for an Executive of the Company, which is attached
hereto as Exhibit 2 and incorporated herein by reference.                                                                                                                                                               
|
| | 3. |  | Other Perquisites and Benefits:The Corporation will provide
the Executive with appropriate office space, as it deems necessary,
and will provide telephone, computer, email and internet access as

|E. |  | COMPENSATION UPON CHANGE
IN CONTROL: Notwithstanding any other
provision in this Agreement, if there is a change in control of the
Corporation (as hereinafter defined) during the Term of this Agreement,
and within twelve (12) months thereafter, either (1) the Executive is
terminated Without Cause (as hereinafter defined in section F) or (2) the
Executives responsibilities are significantly reduced and, as a result,
the Executive terminates his employment pursuant to section J, the
Executive shall be entitled to the compensation and benefits set forth
below. For purposes of this provision, it shall not be considered a
significant reduction in the Executives responsibilities if changes in
these responsibilities are those that would be normally anticipated as a
result of the Corporation becoming a subsidiary or a division of another
company and thus no longer a separately traded public company, provided
that the Executive has responsibilities that would customarily be
associated with those of a chief financial officer of the Corporation as a
private company.

| | 1. |  | Base Compensation:The Corporation shall pay the Executive
sixteen (16) months of his then current base salary. This
compensation will be paid in two parts, as follows: (a) an initial
lump-sum payment of eight (8) months of base salary will be paid
within ten (10) working days of termination of employment and (b)
beginning six (6) months after termination of employment, equal
monthly payments for eight (8) months thereafter. This second
payment in section (b) will be correspondingly reduced by any base
compensation payments the Executive receives through new employment.
The Executive is obligated to inform the Corporation, its
successors and assigns, in writing within ten (10) calendar days of
his acceptance of such new employment and include in this notice
what his base compensation and expected start date are. However, if
the Executives base compensation at such new employment is equal to
or exceeds his prior base salary at the Corporation, the Executive
may simply confirm this fact in the notice in lieu of disclosing the
actual new base compensation figure.

medical benefits coverage under COBRA, the Corporation will pay the
applicable COBRA premium for a period of the lesser of eighteen (18)
months or until such time as the Executive obtains other employment
that provides medical benefits coverage, provided the Executive and
any of his eligible dependents elect COBRA continuation coverage.
This provision is otherwise subject to all applicable COBRA
continuation requirements and does not alter the Corporations right
to amend or terminate its medical plan.

course work eligible for reimbursement under the Corporations
Tuition Assistance Program (Program) or has an education
assistance loan outstanding under that Program, the Corporation will
reimburse any remaining balance due on the course work and forgive
any indebtedness in connection with the outstanding education
assistance loan. This provision is otherwise subject to all
applicable Tuition Assistance Program requirements and does not

contrary, to the extent that any payment or distribution of any type to

the Corporation, any person who acquires ownership or effective control
of the Corporation or ownership of a substantial portion of the
Corporations assets (within the meaning of Section 280G of the Internal
Revenue Code of 1986 as amended (the Code), and the regulations
thereunder), or any affiliate of such person, whether paid or payable or
distributed or distributable pursuant to the terms of this Agreement or
otherwise (the Total Payment), is or will be subject to the excise tax
imposed under Section 4999 of the Code (the Excise Tax), then the Total
Payments shall be reduced (but not below zero) if and to the extent
necessary so that no portion of the Total Payments will be subject to the
Excise Tax. The Corporation shall reduce or eliminate the Total Payments
by first reducing or eliminating the portion of the Total Payments which
is payable in cash and then by reducing or eliminating payments which are
not payable in cash, in each case in reverse order beginning with
payments or benefits which are paid the farthest in time from the
determination that the Total Payments need to be reduced. All
determinations required to be made under this provision shall be made by
a nationally recognized accounting firm that is the Corporations outside
auditor at the time of such determinations.

to appear or to follow the manner of opportunity afforded by the Board or
its committee, the Board, or the delegated committee, may render its
decision without hearing the Executives views.

This Agreement will be construed and enforced as if such illegal, invalid,
or unenforceable provision had never comprised a part hereof, and the
remaining provisions will remain in full force and effect and will not be
affected by the illegal, invalid, or unenforceable provision or by its
severance from this Agreement. Furthermore, in lieu of each such illegal,
invalid, or unenforceable provision, there will be added automatically, as
a part of this Agreement,
