Annual Meeting and in this Proxy Statement.

                              VOTING AT THE MEETING

          This Proxy Statement and the enclosed Proxy are expected to be mailed
on or about April 18, 2008, to all holders of record of common stock of the
Corporation as of the record date. The Board of Directors of the Corporation has
fixed the close of business on March 21, 2008, as the record date for the
determination of shareholders entitled to notice of and to vote at the Annual
Meeting and any adjournment thereof.

          The Corporation's only class of outstanding stock is its common stock,
par value $2.50 per share. As of the record date of March 21, 2008, 1,213,632
shares of common stock of the Corporation were outstanding. Each outstanding
share will entitle the holder thereof to one vote on each separate matter
presented for vote at the meeting. Votes cast at the meeting and submitted by
proxy are counted by the inspectors of the meeting who are appointed by the
Corporation.

          If a Proxy in the enclosed form is properly executed and returned to
the Corporation, the shares represented by the Proxy will be voted at the Annual
Meeting and any adjournment thereof. If a shareholder specifies 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 of the nominees
named in this Proxy Statement and in accordance with the judgment of the persons
named as proxies with respect to any other matter which may come before the
meeting or any adjournment thereof.

          A Proxy may be revoked before exercise by notifying the Secretary of
the Corporation in writing, or by submitting a Proxy of a later date or
attending the meeting and voting in person. All shareholders are encouraged to
date and sign the enclosed Proxy form, indicate your choice with respect to the
matters to be voted upon, and return it to the Corporation.



                              ELECTION OF DIRECTORS

          The Bylaws of the Corporation provide for a Board of Directors
consisting of a minimum of one and a maximum of seventeen members. The Bylaws
also provide that at each annual meeting the shareholders shall elect directors
to hold office until the succeeding annual meeting. A director shall hold office
for the term for which he or she is elected and until his or her successor is
elected and qualified. Directors must be shareholders.

          Ten persons have been nominated for election to the Board, each to
serve one year expiring at the 2009 Annual Meeting of Shareholders. The Board
has nominated Steven J. Baker, D.V.M., James C. Conboy, Jr., Kathleen M. Darrow,
Thomas J. Ellenberger, Susan A. Eno, Vincent J. Hillesheim, Kathleen A. Lieder,

the prior annual meeting of shareholders except for Susan A. Eno who was
appointed to the Board of Directors of the Bank in July 2007.

          Unless otherwise directed by a shareholder's Proxy, the persons named
as proxy holders in the accompanying Proxy will vote for the nominees named
above. In the event any of such nominees shall become unavailable, which is not
anticipated, the Board of Directors in its discretion may designate substitute
nominees, in which event the enclosed Proxy will be voted for such substitute
nominees. Proxies cannot be voted for a greater number of persons than the
number of nominees named.

          A plurality of the votes cast at the meeting is required to elect the
nominees as directors of the Corporation. Shares not voted at the meeting,
whether by abstention, broker non-vote, or otherwise, will not be treated as
votes cast at the meeting.

          THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR ELECTION OF ALL NOMINEES
AS DIRECTORS.

                COMMITTEES AND MEETINGS OF THE BOARD OF DIRECTORS

          The Board of Directors of the Corporation has an Audit Committee. Its
membership is comprised of Directors Ellenberger (who serves as Chairman),
Baker, Darrow, Hillesheim, Lieder, Ormsbee, Swadling and VanAntwerp. All members
qualify as "independent directors" under the NYSE listing standards. Under the
Sarbanes-Oxley Act of 2002 and implementing Securities and Exchange Commission
rules, the Corporation is required to disclose whether the Audit Committee has
at least one member who qualifies as an "audit committee financial expert" as
that term is defined in the rules. Based on the exacting criteria set forth in
the Securities and Exchange Commission rules, the Board of Directors has
determined that no independent member of the Board of Directors qualifies as an
"audit committee financial expert". The present members of the Audit Committee
have 94 years of combined service on the Audit Committee. All of the members are
financially literate and at least one of the members has expertise in accounting
and other aspects of financial management. Considering this experience and
expertise and other relevant issues, the Board of Directors believes that the
Audit Committee can effectively fulfill its duties and obligations and has
determined that appointing an additional director or retaining an individual who
would meet the qualifications of an "audit committee financial expert" is
neither necessary nor reasonable at this time.

          The Audit Committee meets at least quarterly each year and more
frequently as circumstances may require. The Audit Committee met 7 times during
2007. The Audit Committee operates under a written charter adopted by the Board
of Directors, a copy of which is attached as Appendix A to this Proxy Statement.

          The Board of Directors of the Corporation does not have a standing
compensation or nominating committee. The Board of Directors believes that,
given its relatively small size and with eight of its ten current members
qualifying as "independent directors" under the NYSE listing standards, it is
appropriate for the entire Board of Directors to serve in the capacity of a
compensation and nominating committee. The Board of Directors does not have a
charter or other formal written policy with regard to its function as a
compensation or nominating committee.

          Traditionally all directors of the Corporation also serve as the Board
of Directors of the Bank; therefore, director nominees must meet the
qualifications for national bank directors set forth in 12 USC Sec. 72. Based on
those qualifications and Comptroller of the Currency and corporate governance
guidelines, the Board of Directors has developed criteria to be used in
considering individual director candidates. Consideration of factors relative to
the size and composition of the Board of Directors will vary according to the
expertise and demographics of the existing Board. In making nominations for
election to the Board of Directors, the Board of Directors will consider
director candidates recommended by shareholders. Any director candidate
recommended by shareholders will be reviewed and evaluated in the same manner as
all other director candidates.

          Under the Bylaws of the Corporation, nominations of persons for
election to the Board of Directors may be made by any shareholder entitled to
vote at a meeting at which one or more directors will be elected by submitting
written notice of any nomination to the Secretary of the Corporation. The notice
must be received at the principal business office of the Corporation not less


                                       7



than 90 days nor more than 120 days prior to the scheduled date of the annual
meeting, regardless of any postponements, deferrals or adjournments of that
meeting to a later date. In the case of a special meeting of the shareholders or
in the event that the date of the applicable annual meeting is changed by more
than 30 days from its scheduled date, a shareholder's notice must be received no
later than the close of business on the 10th day following the earlier of the
day on which notice of the meeting date was mailed or the day public disclosure
of the meeting was made. The notice must set forth or include (1) the name and
address, as they appear on the records of the Corporation, of the shareholder
giving the notice; (2) a representation that the shareholder giving the notice
is a holder of record entitled to vote at such meeting and intends to appear in
person or by proxy at the meeting to nominate the person or persons specified in
the notice; (3) the class and number of shares of the capital stock of the
Corporation beneficially owned and of record by the shareholder giving the
notice; (4) any material interest or relationship that the shareholder giving
the notice may have with each proposed nominee; (5) the name, address, age,
principal occupation or employment, and such other information for each proposed
nominee as would be required to be included in a proxy statement filed pursuant
to the proxy rules of the Securities and Exchange Commission had the nominee
been nominated, or intended to be nominated, by the Board of Directors; and (6)
a signed consent of each proposed nominee to serve as a director of the
Corporation if so elected.

          As noted above, all directors of the Corporation also serve as the
Board of Directors of the Bank. The Board of Directors of the Corporation held a
total of 7 meetings during 2007, including the organizational meeting. The Board
of Directors of the Bank held a total of 25 meetings during 2007, including the
organizational meeting. All directors attended 75% or more of the aggregate
number of meetings of the two Boards and the Audit Committee, except for Mr.
VanAntwerp who attended 42%. There are no family relationships between or among
any of the directors, nominees or executive officers of the Corporation.

          The directors of the Corporation are expected to attend the Annual
Meeting of Shareholders with the organizational meeting of the newly elected
Board of Directors being held immediately after the shareholders' meeting as
provided in the Bylaws. All directors attended the 2007 Annual Meeting of
Shareholders.

                            COMPENSATION OF DIRECTORS

          All directors 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 elected after
January 1, 1994. The plan is a defined benefit plan and provides for retirement
and death benefits to be paid to the participating directors by the Bank over a
minimum of fifteen years. The plan assumes a retirement age of 70 and uses a
6.00% discount rate in calculating the change in plan value each year. 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 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


                                       8



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 in equal installments over a period of ten years or lump sum if
approved by the Board of Directors.

          During 2007 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 $2,575 for service on the two Boards. The Chairman of the
Board received an additional $375 and the Chairman of the Audit Committee
received an additional $250 quarterly retainer. Directors are not separately
compensated for attendance at Board or Committee meetings, but are reimbursed
for travel expenses for meetings attended.

                      COMPENSATION DISCUSSION AND ANALYSIS

     OVERVIEW

          The Corporation strives to attract, motivate and retain high-quality
executives by providing compensation and benefits that are competitive with
similarly situated banks in the markets in which we compete. The Corporation
provides cash bonuses to advance the interest of shareholders and is
commensurate with the Corporation's performance.

          The Corporation's compensation program for executive officers is
administered by the entire Board of Directors, as well as Susan A. Eno,
President & Chief Executive Officer. At present, all officers of the
Corporation, with the exception of Mr. Hillesheim, the Corporation's Chairman,
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
compensation from the Corporation. Mr. Hillesheim received no compensation as
Chairman of the Corporation. The executive officers serve as officers of the
Corporation as an incident to their primary service as officers and employees of
the subsidiary bank and they receive no compensation directly from the
Corporation. The Board of Directors of the Bank (which is comprised of the same
members as the Board of Directors of the Corporation) has the authority and
responsibility for setting compensation for the Bank's officers, including those
officers who also serve as officers of the Corporation.

     COMPENSATION PHILOSOPHY AND OBJECTIVES

          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 two primary components: base salary and
annual cash bonuses. Longer-term incentive opportunities in the form of stock
option awards have also been awarded in the past. The stock option plan ended in
May, 2006 and there are currently no options in effect that allow further
granting. Senior Vice President and above officers 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 bonuses are
used to reward senior officers and other key employees relating to the
performance of the Corporation.

          In evaluating the performance of and determining the annual base
salary and cash bonus 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 in
the form of stock appreciation and dividends 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


                                       10



establishing the annual base salary and cash bonus for the Chief Executive
Officer and the Corporation's other members of senior management.

          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. 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.

          The Board of Directors goal is to effectively balance salaries with
potential compensation that is performance based commensurate with an officer's
individual management responsibilities and potential for future contribution to
corporate objectives.

     BENCHMARKING

          The Board of Directors reviews information regarding the compensation
levels of other financial institutions, including compensation and benefits
surveys published by the Michigan Bankers Association, Crowe Chizek and Company
LLC and Bank Administrative Institute. The Bank considers itself to be in line
with peers within Michigan and the Midwest, which includes the states of
Illinois, Indiana, Ohio and Wisconsin.

     ELEMENTS OF COMPENSATION

          As noted above, the Bank's compensation program for the Chief
Executive Officer and the Corporation's other senior management is comprised of
two fundamental elements: (1) base salary and (2) annual cash bonuses. The Board
of Directors determines the annual base salary and cash bonus for the Chief
Executive Officer. Annual base salary and cash bonuses 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.

     Base Pay. Base compensation for executive officers is predicated primarily
     on competitive circumstance for managerial talent and positions reflecting
     comparable responsibility.

     Annual Cash Bonuses. Annual cash bonuses are used to reward executive and
     senior officers for the Corporation's overall financial performance. At the
     end of each year the Corporation's performance goal for the following
     year's bonuses are established and is based upon the level of net income
     for the Corporation. Corporation performance bonuses were paid to Mr.
     Conboy ($61,700), Ms. Eno ($15,440) and Mr. Damm ($15,440) as a result of
     the Corporation's 2007 performance.


                                       11



     Perquisites and Other Executive Benefits. Consistent with our compensation
     philosophy, we intend to continue to maintain our current benefits for our
     executive officers, including medical, dental, vision, prescription, group
     term life insurance coverage, disability coverage, Defined Benefit Pension
     Plan and the ability to contribute to a 401(k) Savings Plan with a Bank
     match. These benefits are generally provided to all employees on a
     non-discriminatory basis. We believe these benefits are currently at or
     above median competitive benefits levels for comparable companies. In
     addition to the above benefits, certain executive officers are provided
     automobiles for their use relating to business travels. These automobiles
     are also driven for personal use and the portion of the travel related to
     personal use of the automobiles is included in the All Other Compensation
     column in the Summary Compensation Table along with the other perquisites
     and their related values.

     The Bank does not have employment agreements with any of the Named
     Executive Officers.

plan has not been adopted. All previously awarded stock options were vested
prior to 2007. There were no option exercises during 2007.

     PENSION BENEFITS

          The Corporation has a non-contributory defined benefit pension plan
that is qualified for federal tax purposes for all eligible employees. The
Corporation has the authority to change or terminate the pension plan at any
time. In order to be eligible, an employee must have completed six months of
service and have attained age 20. The employee can participate under the plan
upon the satisfaction of the eligibility requirements and having reached the
entry date. The entry date is the first day of the Plan Year following the date
of satisfaction of the eligibility requirements. The Corporation contributed
$200,000 to the plan in 2007 and $311,000 to the plan in 2006.

          The amount of a participant's monthly normal retirement annuity is
equal to 1.1% of their average monthly compensation (salary and bonus)
multiplied by their total number of years of service, plus .65% of their average
monthly compensation in excess of one-twelfth of their covered compensation
multiplied by their total number of years of service (up to a maximum of
thirty-five (35) years), computed to the nearest cent. Upon reaching normal
retirement age of 65, a participant is entitled to receive, a monthly benefit
for life or may elect a one time lump sum benefit. Early retirement, postponed
retirement and disability retirement are also provided for in the plan.

          A plan participant has no vested benefit until after attainment of 5
years of service at which time the participant is fully vested.

          The plan's benefit obligations at year end are calculated using the
following weighted average assumptions:


                                       14



               -    Weighted average discount - 6.50%

               -    Rate of increase in future compensation - 3.00%

               -    Expected long term rate of return on plan assets - 8.00%

     401K PLAN

     The Bank also maintains a 401(k) plan for all eligible employees. In order
to be eligible, an employee must complete 90 days of service and be at least 21
years of age. During 2007 the Bank elected to make matching contributions equal
to 100% of the first 2% and 50% of the next 2% of the employee's deferred
compensation.

     NONQUALIFIED DEFERRED COMPENSATION

          On September 1, 1997, the board of directors approved a Nonqualified
Deferred Compensation Plan, a supplemental retirement program, which permits
voluntary participation for a select group of management personnel and any
directors not eligible to participate in the 1985 Directors' Deferred
Compensation Plan. Mr. Conboy was the only active employee currently
participating eligible for the benefits under the plan. See Compensation of
Directors above for more information regarding this plan.

          The plan permits participating executive officers and directors to
elect in advance to defer from 1% to 100% of his or her compensation, or
directors fees into the plan on an annual basis. The election to defer
compensation under the plan is irrevocable for each plan year. The Corporation
does not make matching contributions to the plan for employees or directors.
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 employee from the Bank, the
employee will be entitled to receive the balance of his or her account in equal
monthly installments over a period of ten years or lump sum if approved by the
board of directors.

     OTHER POTENTIAL POST-EMPLOYMENT PAYMENTS

          Except for the benefits payable under the defined benefit pension
plan, 401k plan and the deferred compensation plans described above there are no
other contracts, plans, or arrangements that will potentially provide executive
officers with payment or other benefits upon termination of their employment or
upon a change in control of the Corporation or Bank.

                                 CODE OF ETHICS

          The Corporation has adopted a Senior Financial Officers Code of Ethics
that applies to the Corporation's chief executive officer, treasurer, controller
or other senior officers performing similar functions. A copy of the Senior
Financial Officers Code of Ethics will be furnished without charge upon written
request to: Secretary, CNB Corporation, P.O. Box 10, Cheboygan, Michigan 49721.

                          REPORT OF THE AUDIT COMMITTEE

          The primary function of the Audit Committee ("Committee") is to assist
the Board of Directors in fulfilling its oversight responsibilities by reviewing
the financial information that will be provided to shareholders and others, the
systems of internal controls, and all internal and external audit processes.
Management is responsible for preparing the Corporation's financial statements
and the independent external auditors are responsible for auditing those
financial statements.

          The Committee reviewed and discussed the audited financial statements
of the Corporation for the year ended December 31, 2007 with management and the
independent external auditors.

          The Committee discussed with the independent external auditors the
matters required to be discussed by Statement on Auditing Standards 114, which
include, among other items, matters related to the conduct of the audit of the
Corporation's financial statements. The Committee also received the written
disclosures and the letter from the independent external auditors required by
Independence Standards Board Standard No. 1 (which relates to the auditors'
independence from management and from the Corporation and its related entities),
discussed with the auditors any relationships that may impact their independence
and satisfied itself as to the auditors' independence.

          Based on the reviews and discussions referred to above, the Committee
recommended to the Board of Directors that the Corporation's audited financial
statements be included in the Annual Report on Form 10-K for the year ended
December 31, 2007 for filing with the Securities and Exchange Commission.

Submitted by the Audit Committee of the Board of Directors:

         Thomas J. Ellenberger, Chairman             Kathleen A. Lieder
         Steven J. Baker                             John L. Ormsbee
         Kathleen M. Darrow                          R. Jeffery Swadling
         Vincent J. Hillesheim                       Francis J. Van Antwerp, Jr.

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 as counsel to the law firm of Bodman LLP which
provided legal services to the Corporation and the Bank during 2007. During 2007
he received no compensation from Bodman LLP. It is anticipated that Bodman LLP
will continue to furnish legal services in the future.

             SECTION 16(A) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

          Section 16(a) of the Securities Exchange Act of 1934 requires
directors, executive officers, and any persons beneficially owning more than 10%
of the Corporation's common stock to file initial reports of ownership of the
common stock and changes in such ownership with the Securities and Exchange
Commission. Since the Bank essentially has knowledge of such ownership
information in its capacity as sole transfer agent for the Corporation's common
stock, it electronically files the required reports in compliance with Section
16(a), as amended under the Sarbanes-Oxley Act of 2002, and Securities and
Exchange Commission rules and regulations.

INDEPENDENT AUDITORS

          Crowe Chizek and Company LLC ("Crowe Chizek") had served as the
independent external auditors for the Bank since 1980 and for the Corporation
since its formation in 1985. On February 22, 2007, the Audit Committee of our
Board of Directors concluded its proposal process for selection of an
independent registered public accounting firm for 2007, and appointed Plante &
Moran, PLLC ("Plante & Moran") as our independent registered public accounting
firm for the calendar year ending December 31, 2007. On the same date, the Audit
Committee determined to dismiss Crowe Chizek as our independent registered
public accounting firm after work was completed for the calendar year ending
December 31, 2006, and advised Crowe Chizek that it would not be engaged as the
Company's independent registered public accounting firm for the calendar year
ending December 31, 2007.

          The audit report of Plante & Moran on our consolidated financial
statements as of and for the year ended December 31, 2007 and Crowe Chizek's
reports on our consolidated financial statements as of and for the year ended
December 31, 2006, did not contain an adverse opinion or a disclaimer of opinion
and were not qualified or modified as to uncertainty, audit scope, or


                                       17



accounting principles.

          During the two most recent calendar years ended December 31, 2007 and
2006, and from December 31, 2006 through the date we appointed Plante & Moran as
our independent registered public accounting firm for the calendar year ending
December 31, 2007, there have been no disagreements between us and Plante &
Moran or Crowe Chizek on any matters of accounting principle or practice,
financial statement disclosure, or auditing scope or procedure, which
disagreements, if not resolved to its satisfaction, would have caused Plante &
Moran or Crowe Chizek to make reference to the subject matter of such
disagreements in connection with its reports. During the period described in the
preceding sentence, there were no "reportable events" as defined in Item
304(a)(1)(iv) or (v) of Regulation S-K of the Securities and Exchange Commission
("SEC").

          During the calendar year ended December 31, 2006, and from December
31, 2006 through the date we appointed Plante & Moran as our independent
registered public accounting firm for the calendar year ending December 31,
2007, neither we nor anyone on our behalf consulted Plante & Moran with respect
to any accounting or auditing issues involving us. In particular, there was no
discussion with Plante & Moran regarding the application of accounting
principles to a specified transaction, the type of audit opinion that might be
rendered on the financial statements, or any matter that was either the subject
of a disagreement with Crowe Chizek on accounting principles or practices,
financial statement disclosure or auditing scope or procedures, which, if not
resolved to the satisfaction of Crowe Chizek, would have caused Crowe Chizek to
make reference to the matter in its reports, or a "reportable event" as defined
in Item 304(a)(1)(iv) or (v) of Regulation S-K.

          The following table sets forth the fees billed to the Corporation by
Plante & Moran for the year ended December 31, 2007 and Crowe Chizek for the
year ended December 31, 2006:



                       2007      2006
                     -------   -------
                         
Audit Fees           $68,500   $60,800
Audit-Related Fees     5,000         0
Tax Fees              11,000     8,400
All Other Fees        13,500       325


All Other Fees for 2007 included $6,000 paid for a validation of our
Asset/Liability model and $7,500 paid for training services for a credit
analyst.

          All of the services provided by the independent external auditors and
their fees for services were approved in accordance with the Audit Committee's
Audit and Non-Audit Services Pre-Approval Policy. The policy sets forth the
procedures and the conditions pursuant to which the Audit Committee may meet its
duty to pre-approve all audit and permitted non-audit services to be performed
by the independent external auditors. The Audit Committee may give general
pre-approval of types of services based on established policy and procedures or
specific pre-approval on an engagement-by-engagement basis. The Audit Committee
annually reviews and pre-approves


                                       18



those services that may be provided by the independent external auditors without
obtaining specific approval from the Audit Committee.

                    SHAREHOLDER COMMUNICATIONS WITH DIRECTORS

          The Board of Directors does not have a formal process for shareholders
to send communications to the Board of Directors. All members of the Board of
Directors and a large majority of the shareholders reside in the rural
geographic area served by the Corporation and the Bank and open and direct
communication between the directors and those shareholders is encouraged. As for
written communications from shareholders or other interested parties to the
Board of Directors or any specific individual director, the practice has been
and will continue to be that all such communications are promptly forwarded to
the appropriate party or shared with the full Board of Directors no later than
the next regularly scheduled meeting of the Board. Any shareholder wishing to
send a written communication to the Board of Directors or a specific individual
director should address the communication to the Board of Directors or the
individual director, CNB Corporation, 303 N. Main Street, Cheboygan, Michigan
