any reason. For purposes of this Agreement, "Cause" means (i) any willful act of

     3. Compensation and Benefits.

                  (a) Fee. For services performed hereunder, Consultant will be
compensated at the rate of FIFTY THOUSAND DOLLARS ($50,000) per annum, payable
on at least a monthly basis and, to the extent applicable, such compensation
shall be "grossed up" for any social security or Medicare taxes (but not for any
Federal, state or local income tax) payable thereon by Consultant.

                  (b) Life Insurance. During the term of this Agreement, the
Bank agrees to use its commercially reasonable efforts to obtain and maintain a
life insurance policy on the life of Consultant for the benefit of one or more
beneficiaries designated by Consultant. The Bank shall pay all premiums payable
under such policy. The coverage under such policy shall be in an amount equal to
or exceeding the remaining fees payable under Section 3(a) during the Term (the
"Minimum Coverage"). Consultant agrees to cooperate reasonably with the Bank and
its insurance carrier to obtain such a policy and, if necessary, to submit to
reasonable health examinations by physicians. Consultant agrees that, at the
Bank's sole option, such policy may be a "split-dollar" policy, whereby the Bank
and the beneficiaries designated by Consultants would all be payees thereunder,
provided that the amount payable to Consultant's beneficiaries is no less than
the Minimum Coverage.

                  (c) Health Insurance. The Bank agrees to provide coverage to
Consultant and his spouse under the Bank's group health insurance policy through
age 65 on the same basis as employees of the Bank. The Bank will allow
Consultant and his spouse to continue health insurance benefits after age 65
under the Bank's health insurance program on the same basis as retirees of the
Bank. Consultant agrees to pay a portion of the premium for such coverage which
is typically paid by retirees of the Bank under the policy.

     4. Duties and Compensation. Consultant shall provide consulting services to
the Bank and its subsidiaries on a part-time "as needed" basis, at the times and
in the manner such services are reasonably assigned to Consultant by the Bank
consistent with the purpose set forth in the next sentence; provided, however,
that, without his consent, Consultant shall not be required to provide services
hereunder exceeding 250 hours per annum in the aggregate. The parties intend
that the consulting services to be provided hereunder shall be for the purpose
of facilitating the transition of Citizens' business and operations to the Bank,
developing new business opportunities in the market areas served by Citizens,
and advising the Bank regarding corporate and business matters. Consultant will
devote his knowledge, energy, skills and appropriate time to perform his duties
hereunder. During the term of this Agreement, Consultant shall refrain from
providing consulting or advisory services to any bank or financial institution
which competes with the Bank in any market served by Citizens prior to the
merger of Citizens and the Bank.

     5. Business Expenses. Consultant is authorized to incur reasonable and
necessary business expenses in performing his duties under this Agreement. For
this purpose, the Bank agrees to reimburse Consultant for such expenses, upon
presentation of appropriate expense vouchers or receipts to the President and
CEO of the Bank in accordance with the Bank's reimbursement practices.
