COMPENSATION OF DIRECTORS

All directors initially elected prior to January 1, 1994 participate in
the Citizens National Bank of Cheboygan 1985 Directors' Deferred Compensation
Plan in lieu of current payment of director fees. The plan was adopted by the
Bank in 1985 and in 1993 participation in the plan was closed to directors
initially elected after January 1, 1994. The plan provides for retirement and
death benefits to be paid to the participating directors by the Bank over a
minimum of fifteen years. The Bank is the owner and beneficiary of life
insurance policies which are structured to fund the Bank's obligations under the
terms of the plan.

Directors initially elected after January 1, 1994, may participate in
the Citizens National Bank of Cheboygan 1997 Deferred Compensation Plan. The
plan was adopted by the Bank effective September 1, 1997. The plan permits
deferral of all or any portion of current director fees. Amounts deferred are
credited with interest at a rate equal to the Bank's "yield on earning assets"
as calculated at year end of the prior year. Upon separation for any reason of
the services of a participating director from the Bank, the director will be
entitled to receive the balance of his or her account either in a lump sum or in
approximately equal installments over a period of ten years.

During 2002, directors participating in the 1985 Directors' Deferred
Compensation Plan received a deferred annual retainer of $4,000 for service on
the Board of Directors of the Corporation and the Bank. Directors not eligible
to participate in the 1985 Directors' Deferred Compensation Plan received a
quarterly retainer of $2,075 for service on the two Boards. Directors are not
compensated for attendance at Board or Committee meetings, but are reimbursed
for travel expenses for meetings attended.

REPORT ON EXECUTIVE COMPENSATION

The Corporation's compensation program for executive officers is
administered by the entire Board of Directors. At present, all officers of the
Corporation, with the exception of Mr. Ward, the Corporation's Secretary, are
also officers of the Bank, and although they receive compensation from the Bank
in their capacity as officers of the Bank, they receive no separate cash
compensation from the Corporation. Mr. Ward receives no compensation as
Secretary of the Corporation.

The Board of Directors has developed and implemented compensation plans
which seek to align the financial interests of the Corporation's senior officers
with those of its shareholders. The Corporation's executive compensation program
is comprised of three primary components: base salary, annual cash incentive
bonus opportunities and longer-term incentive opportunities in the form of stock
option awards. Executives also participate in the Bank's 401(k) Savings Plan and
Pension Plan and are eligible to participate in the Bank's 1997 Deferred
Compensation Plan.

To attract and retain officers with exceptional abilities and talent,
annual base salaries are set to provide competitive levels of compensation
recognizing individual performance and achievements. Annual cash incentive
bonuses are used to reward senior officers and other key employees for
individual performance, accomplishments and achievement of annual business
targets. A significant portion of career compensation for senior officers is
linked to corporate performance through stock option awards.

The Board of Directors determines the annual base salary, incentive
bonus and stock option awards for the Chief Executive Officer. Annual base
salary, incentive bonus and stock option awards with respect to the
Corporation's other senior officers are recommended by the Chief Executive
Officer to, and ultimately determined by, the Board of Directors. All
recommendations of the Chief Executive Officer were approved by the Board of
Directors for the most recent calendar year.

In evaluating the performance of and determining the annual base
salary, incentive bonus and stock option awards for the Chief Executive Officer
and other senior management, the Board of Directors takes into account
management's contribution to the long-term success of the Corporation. The Board
of Directors considers return to shareholders to be primary in measuring
financial performance. The mission of the Corporation is to maximize long-term
return to shareholders consistent with its commitments to maintain the safety
and soundness of the Corporation and the Bank and provide the highest possible
service at a fair price to the customers and communities that it serves. The
Board of Directors has taken these subjective and qualitative factors into
account, along with other quantitative measures of corporate performance, in
establishing the annual base salary, incentive bonus and stock option awards for
the Chief Executive Officer and the Corporation's other senior management,
giving at least equal weight to the subjective and qualitative factors and no
particular weight to any given factor. The determination of the size of stock
option awards is based

-13-

upon a subjective analysis of each recipient's position within the organization,
his or her individual performance and his or her growth potential within the
organization.

The Board of Directors primarily considers five quantitative measures
of corporate performance in establishing the compensation to be paid to the
Chief Executive Officer and the Corporation's other senior management. These
measures of corporate performance are: (i) after-tax earnings and earnings
growth; (ii) capital position; (iii) quality of the Bank's loan portfolio; (iv)
targeted as compared to actual operating performance; and (v) the Corporation's
performance and financial condition as compared to that of its Federal Reserve
Bank peer group. These measures were considered by the Board of Directors in
determining each component of executive compensation, with particular weight
being given to after-tax earnings and earnings growth. The Board of Directors
also takes into consideration compensation levels at comparable financial
institutions based on various general and targeted compensation surveys of peer
group commercial banks with total assets between $100 and $500 million and
located in the Midwest United States and the state of Michigan.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Directors and officers of the Corporation, as well as members of their
immediate families and the companies, organizations and other entities with
which they are associated, have had, and are expected to have in the future,
transactions with the Bank. All such transactions are made in the ordinary
course of business and on substantially the same terms, including interest rates
and collateral requirements on loan transactions, as those prevailing at the
same time for comparable transactions with other persons. All such loan
transactions do not involve more than normal risk of collectibility or present
other unfavorable features and, when required, are approved by the Board of
Directors.

Director Conboy serves of counsel to the law firm of Bodman, Longley &
Dahling LLP which provided legal services to the Corporation and the Bank during
2002. It is anticipated that Bodman, Longley & Dahling LLP will continue to
furnish legal services in the future.

Director Ward served as a consultant to, and worked on various projects
for, the Bank during 2002 and was compensated $7,400 for his services.

SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section 16(a) of the Securities Exchange Act of 1934 requires

of the Corporation's common stock to file reports of ownership and changes in
ownership of shares of common stock with the Securities and Exchange Commission.
