                                                           EXHIBIT 10(D)(ii)(A)



                                CNB CORPORATION
                             1996 STOCK OPTION PLAN

I.    PURPOSE.

      The purpose of this 1996 Stock Option Plan (the "Plan") is to reward
      certain key executives (the "Participants") of CNB Corporation, a
      Michigan corporation (the "Company") or its Subsidiaries, for their past
      contributions to the Company's goals by allowing these key executives to
      gain a proprietary interest in the Company through ownership of shares of
      the Company's common stock, $2.50 par value ("Common Stock").


II.   PARTICIPANTS.

      Participants will consist of such key executives of the Company or any or
      all of its present or future Subsidiaries as the Board of Directors of
      the Company (the "Board") or the Committee, as defined in Section III
      herein, in its sole discretion, determines to be mainly responsible for
      the success, future growth and profitability of the Company and whom the
      Board or the Committee may designate from time to time to receive Awards
      under the Plan.  Awards may be granted under this Plan to persons who
      have previously received Awards or other benefits under this or other
      plans of the Company.


III. ADMINISTRATION.

      A.    The Plan shall be administered by a committee (the "Committee")
            appointed by the Board.  The Committee shall be composed of not
            fewer than two members of the Board who are not employed by the
            Company. No member of the Committee may exercise discretion with
            respect to, or participate in, the administration of the Plan if,
            at any time, during the twelve-month period prior to such exercise
            or participation, he or she has been granted or awarded stock,
            stock options or any other derivative security of any Company or an
            affiliate thereof under this Plan or any similar plan of the
            Company except as permitted in Rule 16b-3(c)(2)(i)(A) through (D)
            under the Securities Exchange Act of 1934.  In the event the
            Company's Common Stock is registered under the Securities Exchange
            Act of 1934, as amended, members of the Committee shall be subject
            to any additional restrictions necessary to satisfy the
            requirements for disinterested administration of the Plan as set
            forth in Rule 16b-3, as it may be amended from time to time.  No
            member of the Board or the Committee shall be liable for any action
            taken, or determination made, hereunder in good faith.  Service on
            the Committee shall constitute service as a director of the Company
            so

   2

     that members of the Committee shall be entitled to indemnification and
     reimbursement as directors of the Company pursuant to its bylaws.

B.   POWERS. Within the limits of the express provisions of the Plan,
     the Committee shall determine:

     1. The Participants to whom Awards shall be granted;

     2. The time or times at which such Awards shall be granted;

     3. The form and amount of the Awards; and

     4. The limitations, restrictions and conditions applicable to any such 
        Award.

     In making such determinations, the Committee may take into account the
     nature of the services rendered by such Participants, or classes of
     Participants, their present and potential contributions to the Company's
     success and such other factors as the Committee, in its discretion, shall
     deem relevant.  All Awards are subject to the approval of the Board.

C.   INTERPRETATIONS.  Subject to the express provisions of the Plan, the 
     Committee may interpret the Plan, prescribe, amend and rescind rules
     and regulations relating to it, determine the terms and provisions of the
     respective Awards and make all other determinations it deems necessary or
     advisable for the administration of the Plan.

D.   DETERMINATIONS.  The determinations of the Committee, unless otherwise 
     determined by the Board, on all matters regarding the Plan shall be
     conclusive and binding.

E.   NONUNIFORM DETERMINATIONS.  The Committee's determinations under the Plan
     including, without limitation, determinations as to the Participants to
     receive Awards, the terms and provisions of such awards and the agreements
     evidencing the same, need not be uniform and may be made by it selectively
     among Participants who receive or are eligible to receive awards under the
     Plan, whether or not such Participants are similarly situated.

F.   A majority of the Committee shall constitute a quorum, and the acts 
     approved by a majority of the members present at any meeting at
     which a quorum is present or acts approved in writing or by a majority of
     the Committee, shall be acts of the Committee.

IV.  AWARDS UNDER THE PLAN.

      The following provisions shall apply to each award under the Plan. Awards
      shall be in such form and upon such terms and conditions as the Committee
      shall from time to time determine, subject to the following:

      A.    MAXIMUM LIMITATIONS.  The aggregate number of shares of Common
            Stock which will be available for grant under the Plan is 50,000,
            subject to adjustment pursuant to Section IV.C., below.  The
            maximum number of shares which may be issued to a single individual
            is 25,000.  Shares of Common Stock issued pursuant to the Plan
            shall be authorized but unissued shares, or, if permitted under the
            Michigan Business Corporation Act,  shares held in the treasury of
            the Company.  In the event that, prior to the end of the period
            during which Stock Options may be granted under the Plan, any Stock
            Option expires unexercised or is terminated, surrendered or
            canceled without being exercised or vested, in whole or in part,
            for any reason, the number of shares subject to such Award or the
            unexercised, terminated, forfeited or unearned portion thereof,
            shall be added to the remaining number of shares of Common Stock
            available for award under the Plan, including a grant to a former
            holder of such Award, upon such terms and conditions as the
            Committee shall determine, which terms may be more or less
            favorable than those applicable to such former Stock Option.

      B.    FORM.  Awards under the Plan shall be granted in either or both
            of the following forms:

            1. Nonstatutory stock options (NSOs);
            2. Incentive stock options ("ISOs).

            Unless otherwise expressly provided at the time of grant, Options
            granted under the Plan will not be NSOs.

      C.    ADJUSTMENT PROVISIONS.  The aggregate number of shares of Common
            Stock with respect to which awards shall be made, the aggregate
            number of shares of Common Stock subject to each outstanding Stock
            Option and the exercise price per share of each such Stock Option
            may all be appropriately adjusted as the Committee may determine
            for any increase or decrease in the number of shares of issued
            Common Stock resulting from a subdivision or consolidation of
            shares, whether through reorganization, recapitalization, stock
            split-up, stock distribution or combination of shares, or the
            payment of a share dividend or other increase or decrease in the
            number of such shares outstanding effected without receipt of
            consideration by the Company.  Adjustments under this Section IV.C.
            shall be made according to the sole discretion of the Committee,
            and its decisions shall be binding and conclusive.


                                      3
   4


     D. WITHHOLDING TAXES.  Whenever the Company is required to issue or
        transfer shares of Common Stock to a Participant under the Plan, the
        Company shall have the right to require the Participant to remit to the
        Company an amount sufficient to satisfy all federal, state and local
        withholding tax requirements prior to the delivery of any certificate
        or certificates for such shares.  Whenever payments under the Plan are
        to be made to a Participant in cash, such payments shall be net of the
        amount sufficient to satisfy all federal, state and local withholding
        tax requirements.

     E. CONDITIONS OF GRANT.  The Committee, in its discretion, may, as
        a condition to the grant of an Award under the Plan, require a
        Participant who is the recipient of such Award to enter into a  
        covenant not to compete with the Company and its subsidiaries, which
        shall become effective on the date of termination of employment of the
        Participant with the Company, or any other date designated by the
        Committee, and which shall contain such terms and conditions as shall
        be specified by the Committee.

        If the Participant shall fail to enter into any such agreement at the
        request of the Committee, then no Award shall be made hereunder to such
        Participant and the number of shares of Common Stock that would
        have been subject to such Award shall be added to the remaining number
        of shares available for grant as an Award under the Plan.

     F. INVESTMENT REPRESENTATION.  If the Committee, in its discretion,
        determines that as a matter of law such procedure is or may be
        desirable, it may require a Participant upon the exercise of an Option
        or any other acquisition of stock pursuant to the Plan to execute and
        deliver to the Secretary of the Company, the Investment Purpose
        Statement.  This statement warrants that the shares are for the
        Participant's own account, for investment and not with a view to the
        resale or distribution thereof and that subsequent offer of sale or
        sale of any of the shares will be made either pursuant to:

        1.        A Registration Statement on the appropriate form
                  under the Securities Act of 1933 (the "Securities Act") and
                  any applicable state securities laws, which Registration
                  Statement has become effective and is current with respect to
                  the shares being offered and sold; or

        2.        A specific exemption from the registration requirements of 
                  the Securities Act and any applicable state
                  securities laws.  The Company may endorse an appropriate
                  legend referring to the foregoing restriction upon the
                  certificate or certificates representing any shares awarded
                  under the Plan or issued or transferred to the Participant
                  upon the exercise of an Option.






                                      4

     G. ISSUANCE OF STOCK CERTIFICATE.  The Company shall issue, in the name of
        the Participant, stock certificates representing the total number of
        shares of Common Stock issuable pursuant to the exercise of any Stock
        Option ("Option Shares") as soon as reasonably practicable after such
        exercise.  If such shares have not been registered under the Securities
        Act and any applicable state securities laws, the certificates will
        bear the following legend:

        "The shares represented by this certificate have not been registered
        under the Federal Securities Act of 1933, as amended, or state
        securities or Blue Sky laws and may not be sold or transferred in the
        absence of an effective registration statement thereunder or an opinion
        of counsel satisfactory to the Company that such registration is not
        required."


V.   STOCK OPTIONS

     A. OPTION AGREEMENT.  Stock Options granted under this Plan shall
        be subject to such terms and conditions, shall be exercisable at        
        such time or times, and shall be evidenced by such form of written
        option agreement (the "Option Agreement") between the Participant and
        the Company, in form of Exhibit A attached hereto or such other form as
        the Committee shall determine; provided that such determinations are
        not inconsistent with the other provisions of the Plan, or with Section
        422 of the Internal Revenue Code of 1986, as amended (the "Code") for
        qualification as an ISO.

     B. EXERCISE OF STOCK OPTIONS.

        1.        EXERCISE PRICE.  The per share exercise price of each
                  Stock Option shall be fixed by the Committee in the Option
                  Agreement, but shall not be less than 100% of the Fair Market
                  Value (as defined in Section XII.G.) of the Common Stock
                  subject to such Stock Option on the date of grant.

        2.        MANNER OF EXERCISE OF OPTIONS AND PAYMENT FOR STOCK.
                  Any Stock Option granted under the Plan may be exercised by
                  the Participant, a legatee or legatees of such Stock Option
                  under the Participant's last will, or by his or her
                  executors, personal representatives or distributees.

                  a.    NOTICE.  The Option may be exercised by
                        delivering to the Secretary of the Company written
                        notice of the number of shares of Common Stock with
                        respect to which the Stock Option is being exercised.





                                      5

        b.   PAYMENT.  Except as otherwise provided in the Plan or in any Option
             Agreement, the purchase price of Common Stock upon exercise of any
             Stock Option by a Participant shall be paid in full as follows:

             1)    in cash or certified check by the Participant;
             2)    by a broker-dealer to whom the Participant has submitted an
                   exercise notice consisting of a fully endorsed Stock Option;
             3)    in Common Stock valued at its Fair Market Value on the date
                   of exercise;
             4)    by agreeing to surrender Stock Options then exercisable by 
                   him or her valued at the excess of the aggregate Fair Market
                   Value of the Common Stock subject to such Stock Options on 
                   the date of exercise over the aggregate option exercise 
                   prices of such Common Stock;
             5)    by directing the Company to withhold such number of shares 
                   of Common Stock otherwise issuable upon exercise of such 
                   Stock Option having an aggregate Fair Market Value on the 
                   date of exercise equal to the exercise price of the Stock 
                   Option; or 
             6)    by such other medium of payment as the Committee, in its 
                   discretion, shall authorize, or by any combination of 1), 
                   2), 3), 4) or 5) above, at the discretion of the Committee.

             In the case of payment pursuant to 2), 3), 4), 5) or 6) above, the
             Participant's election must be made on or prior to the date of
             exercise of the Stock Option and must be irrevocable. In the case
             of a Participant who is an insider subject to Section 16 of the
             Securities Exchange Act of 1934 and who elects payment pursuant to
             5) above, the election must be made in writing either within ten
             (10) business days beginning on the third (3rd) business day
             following release of the Company's quarterly or annual summary of
             earnings and ending on the twelfth (12th) business day following
             such day, or at least six (6) months prior to the date of exercise
             of such Stock Option.

C.   TERM OF STOCK OPTIONS.  Each Stock Option shall become exercisable at the
     time, and for the number of shares of Common Stock fixed by the Committee
     in the Stock Option Agreement.  Each Stock Option shall expire and all 
     rights to purchase Common Stock thereunder shall cease on the date fixed 
     by the Committee in the Option Agreement, which shall not be later than 
     ten (10) years from the date such Stock Option is granted.

D.   PROVISIONS SPECIFICALLY APPLICABLE TO INCENTIVE STOCK OPTIONS (ISOS).  It
     is intended that ISOs granted under the Plan shall constitute Incentive 
     Stock Options



                                      6
   7

            within the meaning of Section 422 of the Code.  ISOs may be granted
            under the Plan for the purchase of shares of Common Stock.
            Notwithstanding any other provision herein contained, ISOs shall be
            in such form and upon such conditions as the Board shall from time
            to time determine, subject to the following:

            1.    TERM OF OPTIONS.  No Incentive Stock Option shall be
                  exercisable prior to the date one year, or after the date ten
                  years, from the date such ISO is granted.

            2.    LIMITATION ON AMOUNTS.  The aggregate Fair Market Value
                  (determined with respect to each ISO as of the time such ISO
                  is granted) of the Common Stock with respect to which ISOs are
                  exercisable for the first time by an employee during any
                  calendar year (under this Plan or any other plan of the
                  Company or Subsidiary) shall not exceed $100,000.

            3.    TEN PERCENT SHAREHOLDER.  No employee may receive an ISO under
                  the Plan if such employee at the time the award is granted,
                  owns (as defined in Section 424(d) of the Code) stock
                  possessing more than 10% of the total combined voting power of
                  all classes of stock of the Company, its parent or any
                  Subsidiary, unless the option price for such ISO is at least
                  110% of the Fair Market Value of the Common Stock subject to
                  such ISO on the date of grant and such Option is not
                  exercisable after the date five years from the date such
                  Option is granted.


VI.   TRANSFERABILITY.

      No Award made under the Plan may be transferred, assigned, pledged or
      hypothecated (whether by operation of law or otherwise), except to a
      grantor trust (as defined in Sections 671-7 of the Code) or as provided
      by will or the applicable laws of descent or distribution, and no Award
      shall be subject to execution, attachment or similar process.  Any
      attempted assignment, transfer, pledge, hypothecation or other
      disposition of an Award, or levy of attachment or similar process upon
      the Award not specifically permitted herein shall be null and void and
      without effect.  A Stock Option may be exercised only by the Participant
      during his or her lifetime, or pursuant to Section IX.C., by his or her
      estate or the person who acquires the right to exercise such Stock Option
      upon his or her death by bequest or inheritance.

VII.  DISSOLUTION.

      Upon the dissolution or liquidation of the Company, each Stock Option
      granted hereunder shall expire as of the effective date of such
      transaction.




                                      7
   8


VIII. EFFECTIVE DATE AND CONDITIONS SUBSEQUENT TO EFFECTIVE DATE.

             A.   The Plan shall become effective on the date of the
                  approval of the Plan by the Board provided that the
                  shareholders of the Company approve the Plan within 12 months
                  thereafter, and the Plan shall be null and void and of no
                  effect if such condition is not fulfilled.  Stock Options may
                  be granted or awarded before shareholder approval of the Plan
                  but each such Stock Option granted or awarded hereunder shall
                  be subject to shareholder approval of the Plan and if such
                  approval is not obtained, such grants will be null and void
                  and of no effect.

             B.   No grant or award shall be made under the Plan more
                  than ten (10) years from the date of adoption of the Plan by
                  the Board; provided, however, that the Plan and all Awards
                  made under the Plan prior to such date shall remain in effect
                  and subject to adjustment and amendment as herein provided
                  until they have been satisfied or terminated in accordance
                  with the terms of the respective grants or awards and the
                  related Agreements.


IX. TERMINATION OF EMPLOYMENT.

      Each Stock Option shall, unless sooner expired pursuant to Section IX.A,
      B, or C below, expire on the first to occur of the tenth (10th)
      anniversary of the date of grant thereof or the expiration date set forth
      in the applicable Option Agreement.

      A.    OTHER THAN FOR CAUSE, DEATH, OR DISABILITY.  If the
            Participant's employment with the Company and its Subsidiaries is
            terminated for any reason other than cause, death or disability (as
            determined solely by the Board), the Participant will have the
            right for a period of thirty (30) days following such termination,
            or for a period determined at the discretion of the Committee, to
            exercise that portion of the Option, if any, which was exercisable
            by the Participant on the date of termination of employment.  In no
            event shall the Participant have the right to exercise an Option
            subsequent to the expiration date of the Option.

      B.    CAUSE.  If the Participant's employment is terminated for cause,
            as determined by the Board, all Stock Options shall expire on the
            first to occur of the expiration date set forth in the applicable
            Option Agreement, or the date and time of termination of
            employment.

      C.    DEATH OR DISABILITY.  If the employment of a Participant with
            the Company and all Subsidiaries terminates by reason of disability
            (as determined by the Board) or death, the Participant or the
            Participant's legal representative or legatees will have the right
            for a period of six (6) months following such termination, or for a
            period determined

            at the discretion of the Committee, to exercise that portion of the
            Option, if any, which was exercisable by the Participant on the
            date of termination of employment.  In no event shall the
            Participant have the right to exercise an Option subsequent to the
            expiration date of the Option.


X.    CHANGE IN CONTROL.

      Any unexercisable Stock Option will become immediately exercisable and
      any stock restrictions will immediately lapse in the event that a change
      of control occurs as defined in each applicable Agreement.


XI.   POSTPONEMENT OF EXERCISE.

      The Committee may postpone any exercise of a Stock Option for such time
      as the Committee, in its sole discretion, may deem necessary in order to
      permit the Company to:

      A.    Effect, amend or maintain any necessary registration of the Plan
            or the shares of Common Stock issuable upon the exercise of a Stock
            Option under the Securities Act of 1933, as amended, or the
            securities laws of any applicable jurisdiction;

      B.    Permit any action to be taken in order to:

            1.    List such shares of Common Stock on a stock exchange
                  if shares of Common Stock are then listed on such exchange;
                  or

            2.    Comply with restrictions or regulations incident to
                  the maintenance of a public market for its shares of Common
                  Stock, including any rules or regulations of any stock
                  exchange on which the shares of Common Stock are listed; or

      C.    Determine that such shares of Common Stock and the Plan are
            exempt from such registration or that no action of the kind
            referred to in XI.B above needs to be taken; and the Company shall
            not be obligated by virtue of any terms and conditions of any
            Option Agreement or any provision of the Plan to recognize the
            exercise of a Stock Option, or to sell or issue shares of Common
            Stock in violation of the Securities Act or the law of any
            government having jurisdiction thereof.  Any such postponement
            shall not extend the terms of a Stock Option and neither the
            Company nor its directors or officers shall have any obligation or
            liability to any Participant or any other person with respect to
            any shares of Common Stock as to which the Stock Option shall lapse
            because of such postponement.

XII. MISCELLANEOUS.

        A.  NO OBLIGATION TO EXERCISE OPTIONS.  The granting of a Stock Option
            shall impose no obligation upon a Participant to exercise such Stock
            Option.

        B.  TERMINATION AND AMENDMENT OF PLAN.  The Board, without further
            action on the part of the shareholders of the Company, may from time
            to time alter, amend or suspend the Plan or any Stock Option granted
            hereunder or may at any time terminate the Plan, except that, it may
            not without approval of the shareholders of the Company (except to
            the extent provided in Section IV.C. hereof):

            1.  Materially increase the total number of shares of
                Common Stock available for grant to Section 16 insiders under
                the Plan;

            2.  Materially increase benefits to Participants under
                the Plan;

            3.  Effect a change relating to ISOs granted hereunder
                which is inconsistent with Section 422 of the Code or
                regulations issued thereunder; or

            4.  Change the class of persons eligible to be
                Participants.

            No action taken by the Board, with or without shareholder approval,
            under this Section may materially and adversely affect any
            outstanding Award without the consent of the holder thereof.

        C.  APPLICATION OF FUNDS.  The proceeds received by the Company from
            the sale of Common Stock pursuant to the Plan will be used for
            general corporate purposes.

        D.  RIGHT TO TERMINATE EMPLOYMENT.  Nothing in the Plan or any agreement
            entered into pursuant to the Plan shall confer upon any Participant
            the right to continue in the employment of the Company or any
            Subsidiary or affect any right which the Company or any Subsidiary
            may have to terminate the employment of such Participant.

        E.  RIGHTS AS A SHAREHOLDER.  No Participant shall have any right or
            privilege as a shareholder unless and until certificates for shares
            of Common Stock are issuable to him or her.

        F.  LEAVES OF ABSENCE AND DISABILITY.  The Committee shall be entitled
            to make such rules, regulations and determinations as it deems
            appropriate under the Plan in respect of any leave of absence taken
            by or disability of any Participant. Without limiting the generality
            of the foregoing, the Committee shall be entitled to determine:

                                      10
   11


                 1.  Whether or not any such leave of absence shall constitute a
                     termination of employment within the meaning of the Plan; 
                     and

                 2.  The impact, if any, of any such leave of absence on Awards 
                     under the Plan theretofore made to any Participant who 
                     takes such leave of absence.

            G.   FAIR MARKET VALUE.  Whenever the Fair Market Value of Common
                 Stock is to be determined under the Plan as of a given date, 
                 such Fair Market Value shall be:

                 1.  If the Common Stock is principally traded on an exchange
                     or market in which prices are reported on a bid and asked
                     basis, the average of the mean between the bid and the
                     asked price for the Common Stock at the close of trading   
                     for the 10 consecutive trading days immediately preceding
                     such given date;

                 2.  If the Common Stock is principally listed on a national
                     securities exchange, the average of the closing prices of
                     the Common Stock on the Composite Tape for the 10
                     consecutive trading, days immediately preceding such given
                     date; or

                 3.  If the Common Stock is neither traded on the over the
                     counter market nor listed on a national securities 
                     exchange, such value as the Board, in good faith, shall 
                     determine.

            H.   NOTICES.  Every direction, revocation or notice authorized or
                 required by the Plan shall be deemed delivered to the Company:

                 1.  On the date it is personally delivered to the Secretary of
                     the Company at its principal executive offices; or

                 2.  Three business days after it is sent by registered or
                     certified mail; postage prepaid, addressed to the Secretary
                     at such offices.

                 and to a Participant:

                 3.  On the date it is personally delivered to him or her; or

                 4.  Three business days after it is sent by registered or
                     certified mail, postage prepaid, addressed to him or her at
                     the last address shown for him or her on the records of the
                     Company.

            I.   ELIMINATION OF FRACTIONAL SHARES.  If under any provision of 
                 the Plan that requires a computation of the number of shares of
                 Common Stock subject to an Award, the number so computed is not
                 a whole number of shares of Common Stock, such number of shares
                 shall be rounded down to the next whole number.

        J.      GOVERNING LAW.  All questions pertaining to the validity,
                construction and administration of the plan and Awards granted
                hereunder shall be determined in conformity with the laws of the
                State of Michigan.

     F)    by such other medium of payment as the Committee, in its
           discretion, shall authorize, or by any combination of 1), 2), 3), 4)
