Section 2.     Compensation and Reimbursement.
(a)    Consulting Fees. As consideration for the performance of Services by the
Consultant hereunder, the Company shall pay the Consultant during the
Consultation Period consulting fees in the amount of $41,666.67 per month (the
“Consulting Fees”), to be paid to the Consultant at the end of each month.
(b)    Expense Reimbursement. The Company shall reimburse the Consultant for all
reasonable out-of-pocket expenses incurred by the Consultant in connection with
the performance of the Services under this Agreement, so long as they are
approved in writing in advance by the Company.
(c)    Health Insurance Payments. Should the Consultant be eligible for and
elect to remain on the Company’s group health and/or dental insurance plan(s) as
an active enrollee, he shall be entitled to remain on such plan(s) through the
end of the Consultation Period, and the Company shall contribute to the cost of
the Consultant’s group health and/or dental insurance plan(s) at the same rates
as from time to time in effect for the Company’s active workforce. If the
Consultant is not or ceases to be eligible to remain on the Company’s group
health and/or dental insurance plan(s) and is eligible for and timely elects to

Consultation Period or (y) the date that the Consultant is no longer eligible
for and enrolled in COBRA continuation coverage, continue to contribute on the
Consultant’s behalf the employer premium for such coverage at the same rates as
from time to time in effect for the Company’s active workforce. Should the
Consultant cease during the Consultation Period to be eligible to continue
receiving group health and/or dental insurance coverage under COBRA for reasons
other than becoming enrolled in another group health plan, the Company shall
provide the Consultant with an additional monthly payment for the duration of
the Consultation Period in an amount equal to the monthly employer premium paid
during the final month of his COBRA continuation coverage.
(d)    Itemized Statements. At the end of any month in which the Consultant
performs Services and incurs expenses in accordance with Section 2(b), the
Consultant shall submit to the Company an itemized statement of the expenses
incurred, including appropriate and reasonable documentation. The Company shall
pay the Consultant the amount set forth on such itemized statement within
forty-five (45) days after receipt.
(e)    No Employee Benefits. The Consultant’s relationship with the Company will
be that of an independent contractor, and the Consultant shall not, in
connection with this relationship, be entitled to any benefits, coverages or
privileges, including without limitation social security, unemployment, workers
compensation, pension payments, administrative support (other than as may be
approved by the Company’s Chief Executive Officer, Chief Financial Officer or
Chief Operating Officer) or office space on the Company’s premises, made
available to employees of the Company.
Section 3.     Term and Termination.
(a)    Consultation Period. Subject to the terms and conditions hereinafter set
forth, the term of this Agreement (the “Consultation Period”) shall, provided
the Consultant has timely entered into the Separation Agreement, commence on the
Effective Date and continue until terminated as set forth in this Section 3(a)
(and provided that the Consultation Period shall automatically terminate upon
the death, physical incapacitation or mental incompetence of the Consultant).

Date, nor shall the Consultant be deemed to be at any time during the

relationship with the Company shall be that of an independent contractor and
consultant. The Consultant is not authorized to assume or create any obligation
or responsibility, express or implied, on behalf of, or in the name of, the
Company or to bind the Company in any manner. Nothing herein shall create,
expressly or by implication, a partnership, joint venture or other association
between the parties. The Consultant shall be solely responsible for payment of

parties and are not to be construed as a substantive provision hereof. This
Agreement may not be modified or amended except in writing signed or executed by
the Consultant and the Company. In the event any provision of this Agreement is
held to be unenforceable or invalid, such unenforceability or invalidity shall
not affect any other provisions of this Agreement and such other provisions
