                                  P.O. Box 280
                           101 North Pine River Street
                             Ithaca, Michigan 48847


         This proxy statement is being furnished to holders of common stock,
with no par value ("Common Stock"), of Commercial National Financial Corporation
(the "Corporation") in connection with the solicitation of proxies by the
Corporation's board of directors for use at the annual meeting of shareholders
to be held on April 22, 2003, and at any adjournment of that meeting. The annual
meeting will be held at the Ithaca Community Center, 120 North Maple Street,
Ithaca, Michigan 48847, at 7:00 p.m. for the purposes set forth in the
accompanying Notice of Annual Meeting of Shareholders. This proxy statement and
form of proxy are first being sent to shareholders on or about March 26, 2003.

         If a proxy in the form distributed by the Corporation is properly
executed and returned to the Corporation, the shares represented by that proxy
will be voted at the annual meeting of shareholders and at any adjournment of
that meeting. Where a shareholder specified a choice, the proxy will be voted as
specified. If no choice is specified, the shares represented by the proxy will
be voted for the election of all nominees to the board of directors. Management
does not know of any other matters to be presented at the annual meeting. If
other matters are presented, all proxies will be voted in accordance with the
judgment of the persons named as proxies, who will consider management's
recommendations.

         A proxy may be revoked at any time prior to the closing of the polls by
written notice delivered to the President of the Corporation, by a subsequent
dated proxy, or by voting the shares represented by the proxy at the annual
meeting.

         Solicitation of proxies will be made initially by mail. Officers,
directors and employees of the Corporation and its wholly owned subsidiary,
Commercial Bank (the "Bank"), may also solicit proxies in person or by telephone
without additional compensation. In addition, proxies may be solicited by
nominees and other fiduciaries, who may mail material to or otherwise
communicate with the beneficial owners of shares held by them. All expenses of
solicitation of proxies will be paid by the Bank.

                              ELECTION OF DIRECTORS


         The board of directors of the Corporation has nominated the following
10 persons for election to the board of directors at the annual meeting:

         Richard F. Abbott          Patrick G. Duffy        Howard D. Poindexter
         Jefferson P. Arnold        David A. Ferguson       Scott E. Sheldon
         Jeffrey S. Barker          Paul B. Luneack
         Don J. Dewey               Kim C. Newson

         Directors are to be elected at the annual meeting of shareholders to
serve until the next following annual meeting of shareholders. The proposed
nominees are willing to be elected and to serve. In the event that any nominee
is unable to serve or is otherwise unavailable for election, which is not now
contemplated, the incumbent Corporation board of directors may or may not select
a substitute nominee. If a substitute nominee is selected, all proxies will be
voted for the person so selected. If a substitute nominee is not so







selected, all proxies will be voted for the election of the remaining nominees.
Proxies will not be voted for a greater number of persons than the number of
nominees named.

         A vote of shareholders holding a plurality of shares is required to
elect directors. For the purpose of counting votes on this proposal,
abstentions, broker non-votes, and other shares not voted will not be counted as
shares voted, and the number of votes of which a plurality is required will be
reduced by the number of shares not voted.

         It is the Corporation's practice to award stock options annually to key
policy making members of management. Stock options have been an important
component of the Corporation's executive compensation program for several years.
Stock options are believed to help align the interests of senior management with
the interests of shareholders by promoting stock ownership by senior executive
officers and by rewarding them for appreciation in the price of the
Corporation's Common Stock. Stock options which were granted, exercised, or
outstanding during 2002 were granted under the 1991 Stock Option Plan and the
2001 Stock Option Plan. The 1991 Stock Option Plan terminated by its terms on
April 22, 2001. The Corporation's shareholders have approved the 2001 Stock
Option Plan.

         The Corporation's 1991 Stock Option Plan and 2001 Stock Option Plan
provide that stock options, stock appreciation rights, and tax benefit rights
may be issued to directors, officers, and key employees. Stock options entitle a
participant to buy shares of Common Stock of the Corporation during a specified
time period at a specified price. Subject to restrictions imposed by the Plan,
the human resource committee in its discretion determines who will be granted
options, how many shares will be subject to options, and the form of
consideration that may be paid upon exercise of an option. As of December 31,
2002, a maximum of 83,510 authorized shares are subject to the exercise of
options under the 2001 plan. As of December 31, 2002, a maximum of 148,329
authorized shares are subject to the exercise of options under the 1991 plan. As
of December 31, 2002, no stock appreciation rights had been granted under the
plan. The 1991 Stock Option Plan terminated by its terms on April 22, 2001.

         The following tables set forth information concerning stock options
granted to and exercised or retained by the named executive officers of the
Corporation and Bank during 2002. In 2002, the Corporation granted options under
the 2001 Stock Option Plan. As indicated in the following table, options awarded
in 2002 are exercisable for ten years.

(1)      The per share exercise price of each option is equal to the market
         value of the Common Stock on the date each option was granted. The
         option information has been adjusted to reflect the 5% stock dividend
         paid in November of 2002. All outstanding options were granted for a
         term of ten or fewer years. Options terminate subject to certain
         limited exercise provisions, in the event of death, retirement, or
         other termination of employment. In the event of a change in control of
         the Corporation, a participant may exercise tax benefit rights granted
         in tandem with the options. Such tax benefit rights would entitle an
         optionee to cash payments at the time of exercise to partially
         reimburse the optionee for tax liability.

CHANGE OF CONTROL ARRANGEMENT

         The Bank has entered into a Change of Control Arrangement with named
executive officers Jeffrey S. Barker, Patrick G. Duffy, and Andrew P. Shafley
providing that if certain "employment changes" occur within 24 months after a
"change of control" of the Corporation, then they shall receive a lump sum
severance payment equal to 1 1/2 times their yearly salary and bonus.

         The Arrangement generally defines employment changes as follows:
termination of employment for reasons other than good cause; a significant
change in the nature or scope of their authority or in the overall working
environment; their assignment to duties materially inconsistent with their
present duties, responsibilities and status; or a material reduction in their
monthly rate of base salary. A change of control occurs for purposes of the
Arrangement when more than 50% of the Corporation's common stock is acquired by
an entity, person or group.

         The Bank's purpose in entering into the Arrangement with Mr. Barker,
Mr. Duffy, and Mr. Shafley is to provide these individuals with financial
security following a change of control and to provide an additional inducement
for them to remain employed by the Bank. With continuation of their employment
reasonably assured, the Corporation and its shareholders should be more assured
that they will act, with respect to a possible change of control, for the
benefit of the Corporation and its shareholders and without concern for their
own financial security.






                                       8


COMPENSATION OF DIRECTORS

         The board of directors of the Bank holds regular monthly meetings. The
Bank compensates its directors at the rate of $1,000 per month. The Chairman of
the board is paid $2,000 per month. Directors of the Bank, who are not executive
officers, are paid $150 for each committee meeting attended. The Corporation's
board of directors meetings customarily coincide with Bank board of directors
meetings. No separate cash compensation is paid to directors for Corporation
board of directors meetings.

         The directors of the Corporation and Bank may receive stock options
under the Corporation's 2001 Stock Option Plan. The number of shares of Common
Stock covered by each option equals the number of shares the director could
purchase if he had purchased shares with the directors fees that the director
earned during the year. The options awarded to the directors are exercisable
after six months from the date of grant and expire ten years from the date of
grant.

deemed to be incorporated by reference into any prior or subsequent filing by
the Corporation under the Security Act of 1933 or the Securities Exchange Act of

letter from the independent auditors required by Independence Standards Board
Standard No. 1 (which relates to the auditor's independence from the Corporation
and its related entities) and has discussed with the auditors the auditors'

referred to above, the Audit Committee recommended to the Board of Directors
that the Consolidated Financial Statements be included in the Corporation's
Annual Report on Form 10-K for the year ended December 31, 2002 for filing with
the Securities and Exchange Commission.

         Audit Committee Charter The Board of Directors and Audit Committee have
adopted an Audit Committee Charter.

defined in Rule 4200(a)(15) of the National Association of Securities Dealers'
listing standards.

RELATIONSHIP WITH INDEPENDENT CERTIFIED PUBLIC ACCOUNTANTS

         The firm of Crowe, Chizek and Company LLP examined and certified the
financial statements of the Corporation for the year ended December 31, 2002.
Upon the recommendation of the Audit Committee, the






                                       9



Board of Directors has selected Crowe, Chizek and Company LLP to act as the
Corporation's independent auditors for 2003.

shareholders and to make any comments deemed appropriate.


CERTAIN RELATIONSHIPS

         Directors and officers of the Corporation and members of their
immediate families and businesses controlled by them were customers of and had
certain transactions with the Bank in the ordinary course of business since
January 1, 2002. It is anticipated that such transactions will take place in the
future in the ordinary course of business. All loans and commitments included in
such transactions were made on substantially the same terms, including interest
rates, fees, and collateral, as those prevailing at the time for comparable
transactions with other persons and did not involve more than normal risk of
collectibility or present any unfavorable features.

         During 2002, the Bank retained the services of Mr. Arnold, an attorney,
for routine legal matters. These fees were billed at the regular rates charged
by Mr. Arnold for services rendered to all of his firm's clients. The fees paid
by the Bank did not exceed 5% of the firm's gross revenues for its last fiscal
year.
