      This Proxy Statement and the enclosed Proxy are furnished in connection
with the solicitation of proxies by the Board of Directors of CNB Corporation
(the "Corporation"), a Michigan bank holding company whose sole subsidiary is
Citizens National Bank of Cheboygan (the "Bank"), to be voted at the Annual
Meeting of Shareholders of the Corporation to be held on May 16, 2006, at 5:30
p.m., at the Knights of Columbus Hall, 9840 South Straits Highway, Cheboygan,
Michigan (the "Annual Meeting"), or at any adjournment or adjournments thereof,
for the purposes set forth in the accompanying Notice of 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 14, 2006, 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 17, 2006, 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 17, 2006, 1,237,582 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.

      Nine persons have been nominated for election to the Board, each to serve
one year expiring at the 2007 Annual Meeting of Shareholders. The Board has
nominated Steven J. Baker, D.V.M., James C. Conboy, Jr., Kathleen M. Darrow,

are incumbent directors elected by the Corporation's shareholders at the prior
annual meeting of shareholders except for Ms. Lieder and Mr. Swadling who were
appointed to the Board of Directors of the Bank in September 2005.

      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 Hillesheim (who serves as Chairman), Baker,
Darrow, Ellenberger, Ormsbee 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 78 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 6 times during 2005. 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
nominating committee. The Board of Directors believes that, given its relatively
small size and with six of its eight 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 nominating committee. The Board
of Directors does not have a charter or other formal written policy with regard
to its function as a 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 5 meetings during 2005, including the organizational meeting. The Board of
Directors of the Bank held a total of 26 meetings during 2005, 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 70%. 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 2005 Annual Meeting of Shareholders.

                          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, 2005 with management and the
independent external auditors.

                                      -8-


      The Committee discussed with the independent external auditors the matters
required to be discussed by Statement on Auditing Standards 61, 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, 2005 for filing with the Securities and Exchange Commission.

Submitted by the Audit Committee of the Board of Directors:

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

                                 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.

                            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

                                      -9-


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 2005 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 $2,450 for service on the two Boards. The Chairman of the
Board and the Chairman of the Audit Committee receive an additional $250
quarterly retainer. 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, including John P. Ward, Chairman;
James C. Conboy, Jr., President & Chief Executive Officer; and Susan A. Eno,
Executive Vice President & Secretary. At present, all officers of the
Corporation, with the exception of Mr. Ward, 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 cash
compensation from the Corporation. Mr. Ward receives no compensation as Chairman
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

                                      -13-



form of stock option awards. Executive officers also participate in the Bank's
401(k) Savings Plan and Defined Benefit 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 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. 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 LLP which
provided legal services to the Corporation and the Bank during 2005. During 2005
he received no compensation from Bodman LLP. It is anticipated that Bodman 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 2005 and was compensated $7,200 for his services.

             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.

      Crowe Chizek and Company LLC has served as the independent external
auditors for the Bank since 1980 and for the Corporation since its formation in
1985 and the Audit Committee has selected Crowe Chizek and Company LLC to serve
as the Corporation's independent external auditors for 2006. A representative of
Crowe Chizek and Company LLC is not expected to be at the Annual Meeting of
Shareholders.

fees for a cost segregation study and review of a new markets tax credit
application.

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

      The Board of Directors does not have a formal process for shareholders to

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

                                       16

                                 CNB CORPORATION
                             AUDIT COMMITTEE CHARTER

ORGANIZATION

There shall be a committee of the Board of Directors to be known as the Audit
Committee. The Audit Committee shall be composed of all members of the Board of
Directors who qualify as "independent directors" under the NYSE Standards of
Independence. At least one member must have expertise in accounting or other
aspects of financial management and all members are expected to be financially
literate or to gain such literacy after appointment. The Audit Committee shall
meet at least quarterly each year and more frequently as circumstances may
require.

PURPOSE

The Audit Committee shall assist the Board of Directors in fulfilling its
responsibility to shareholders, potential shareholders, the investment
community, and others relating to the accounting and financial reporting
processes and practices of the Corporation and the quality and integrity of the
financial reports of the Corporation. In so doing, the Audit Committee shall
maintain free and open means of communication between the Board of Directors,
the independent external auditors, the internal auditors and the management of
the Corporation.

RESPONSIBILITIES AND AUTHORITY

The Audit Committee is responsible for determining the specific policies and
procedures it needs to carry out its responsibilities and believes such policies
and procedures should remain flexible, in order to best react to changing
conditions and to ensure to the Board of Directors and shareholders that the
accounting and financial reporting practices of the Corporation are in
accordance with all requirements and are of the highest quality. The Audit
Committee shall have the following responsibilities and authority:

- -     Appoint, evaluate and, where appropriate, replace, and approve the
      compensation of the independent external auditors engaged to audit the
      financial statements of the Corporation or perform other audit, review or
      attest services. The independent external auditors shall report directly
      to the Audit Committee and the Committee shall oversee the work of the
      independent external auditors, including resolution of any disagreements
      between management and the independent external auditors.

- -     Pre-approve all audit and permitted non-audit services of the independent
      external auditors and approve all engagement fees and terms in accordance
      with the Audit and Non-Audit Services Pre-Approval Policy.

- -     Review at least annually all relationships between the independent
      external auditors and the Corporation to assess the auditors' independence
      and their compliance with auditing rules and standards, including the
      rotation of lead audit and concurring review partners.



- -     Review and discuss with the independent external auditors and management
      the scope of the proposed audit for the current year and the audit
      procedures to be utilized. Receive and review the results of the audit,
      including any comments or recommendations of the independent external
      auditors and management's response to them.

- -     Review with the independent external auditors and the internal auditors
      the adequacy and effectiveness of the accounting and financial controls of
      the Corporation and elicit any recommendations for the improvement of such
      internal control procedures or particular areas where new or more detailed
      controls or procedures are desirable. Particular emphasis will be given to
      the adequacy of such internal controls to expose inaccurate, incomplete or
      unauthorized transactions, deficiencies in the safeguarding of assets,
      unreliable financial and regulatory reporting, and deviations from laws,
      regulations, corporate policies or the code of conduct.

- -     Annually evaluate the adequacy and effectiveness of the internal audit
      function including its structure and appoint, replace, and approve the
      compensation of any outside audit firm performing any of the internal
      audit functions. Review and approve the proposed risk assessment and the
      internal audit plan for the coming year and the coordination of such plan
      with the independent external auditors.

- -     Review and approve the appointment, replacement, reassignment or dismissal
      of the manager of internal audit. Annually evaluate the competence and
      performance of the manager of internal audit, limiting senior management's
      input into the evaluation to administrative details.

- -     Receive and review at each regular meeting a summary of findings and
      recommendations from completed internal audits, together with management's
      response where appropriate, and a progress report on the internal audit
      plan, with explanations for any deviations from the approved plan.

- -     Provide sufficient opportunity for the Audit Committee to meet separately
      with the internal auditors and the independent external auditors, without
      members of management present, to discuss the results of their
      examinations or any other matters either of the parties believe should be
      discussed privately.

- -     Review and discuss with management and the independent external auditors
      the audited financial statements prior to their being included in the
      annual report to shareholders or reports to be filed with the Securities
      and Exchange Commission or other regulators, and discuss with the
      independent external auditors any matters required to be communicated to
      the Audit Committee by the independent external auditors under generally
      accepted auditing standards.

                                       2



- -     Review and discuss with management and the independent external auditors
      the interim financial statements prior to their being included in reports
      to be filed with the Securities and Exchange Commission or other
      regulators and discuss with the independent external auditors any matters
      required to be communicated to the Audit Committee by the independent
      external auditors under generally accepted auditing standards.

- -     Review with the independent external auditors, internal auditors and
      management changes and developments in accounting, financial reporting, or
      auditing standards and principles, or any other legal or regulatory
      matters that may have a significant effect on the Corporation's financial
      statements or the audit process.

- -     Issue the report required by the Securities and Exchange Commission to be
      included in the Corporation's annual proxy statement and cause a copy of
      this Audit Committee Charter, as it may be amended from time to time, to
      be published in the annual proxy statement in compliance with applicable
      rules and regulations.

- -     Establish and maintain procedures for the receipt, retention and treatment
      of complaints regarding accounting or auditing matters, including
      procedures necessary to receive and respond to confidential and anonymous
      submissions by employees regarding questionable accounting or auditing
      matters. Investigate any matter brought to its attention within the scope
      of its responsibilities, with full access to all books, records,
      facilities and personnel of the Corporation, and with the power to retain
      outside counsel or other experts for this purpose.

- -     Keep written minutes of all Audit Committee meetings and report to the
      Board of Directors on matters discussed and all actions taken at each
      meeting.

- -     Review at least annually the adequacy of this Charter and recommend any
      proposed changes to the Board of Directors for approval.
