(e) Effect on Shares. At the Effective Time, by virtue of the Merger and without any action on the part of C&N, Citizens or the holders of any of the following securities, the following shall occur:

(i) Outstanding C&N Common Stock. Each share of C&N Common Stock issued and outstanding immediately prior to the Effective Time shall continue to be issued and outstanding as an identical share of C&N Common Stock, except that shares of C&N Common Stock owned by Citizens (other than shares held in trust, managed, custodial or nominee accounts and the like that in any such case are beneficially owned by third parties and shares acquired in respect of debts previously contracted) shall become treasury stock of C&N.

(ii) Cancellation of Certain Common Stock. Each share of Citizens Common Stock that is owned by C&N, by Citizens as treasury shares, or by any of their respective Subsidiaries (other than shares that are held in trust, managed, custodial or nominee accounts and the like and that are beneficially owned by third parties and other than shares acquired in respect of debts previously contracted) shall be canceled and cease to be issued and outstanding, and no consideration shall be delivered therefor.

(iii) Conversion of Citizens Common Stock. Each share of Citizens Common Stock issued and outstanding immediately prior to the Effective Time (other than shares canceled pursuant to Section 1.02(e)(ii) and Dissenting Citizens Shares) shall be converted into the right to receive, at the election of the holder thereof either: (A) 1.297 shares of C&N Common Stock, subject to adjustment as provided in Section 1.02(j) below (the “Stock Consideration”), or (B) $28.57 in cash (the “Cash Consideration”). Notwithstanding the foregoing, and giving effect to Section 1.02(e)(ii) hereof, (1) the number of shares of Citizens Common Stock to be converted into the right to receive the Stock Consideration on the Effective Date shall be equal to fifty percent (50%) of the total number of shares of Citizens Common Stock issued and outstanding on the Effective Date and (2) the number of shares of Citizens Common Stock to be converted into the right to receive the Cash Consideration on the Effective Date shall be equal to fifty percent (50%) of the total number of shares of Citizens Common Stock issued and outstanding on the Effective Date, minus (x) the number of Dissenting Citizens Shares, if any, and (y) the aggregate number of shares with respect to which cash is paid in lieu of fractional shares pursuant to Section 1.02(e)(iv).

(iv) Cash in Lieu of Fractional Shares. Notwithstanding anything herein to the contrary, no fraction of a whole share of C&N Common Stock and no scrip or certificate therefore shall be issued in connection with the Merger. Any former Citizens shareholder who would otherwise be entitled to receive a fraction of a share of C&N Common Stock shall receive, in lieu thereof, cash in an amount equal to such fraction multiplied by the Average Closing Price.

(v) Dissenting Citizens Shares. The outstanding shares of Citizens Common Stock, the holders of which have timely filed written notices of an intention to demand appraisal for their shares (“Dissenting Citizens Shares”) pursuant to Subchapter D of Chapter 15 of the BCL and have not effectively withdrawn or lost their dissenters’ rights under the BCL, shall not be converted into or represent a right to receive the Merger Consideration under this Agreement, and the holders thereof shall be entitled only to such rights as are granted by Subchapter D of Chapter 15 of the BCL. If any such holder of Citizens Common Stock shall have failed to perfect or shall have withdrawn or lost such right, the Dissenting Citizens Shares held by such holder shall thereupon be treated as No Election Shares.

(f) Election Procedures. C&N shall cause the Exchange Agent to mail an Election Form to holders of Citizens Common Stock not more than fifty (50) Business Days and not less than twenty (20) Business Days prior to the Election Deadline. Each Election Form shall permit the holder (or in the case of nominee record holders, the beneficial owner through proper instructions and documentation):

(i) To elect to receive the Stock Consideration with respect to all of their shares of Citizens Common Stock (the “Stock Election Shares”); or

(ii) To elect to receive the Cash Consideration with respect to all of their shares of Citizens Common Stock (the “Cash Election Shares”); or

(iii) To elect to receive the Stock Consideration with respect to a specified number of their shares of Citizens Common Stock and the Cash Consideration with respect to their remaining shares of Citizens Common Stock (a “Mixed Election”). With respect to each holder of Citizens Common Stock who makes a Mixed Election, their shares of Citizens Common Stock to be converted into the right to receive the Stock Consideration shall be treated as Stock Election Shares and their shares of Citizens Common Stock to be converted into the right to receive the Cash Consideration shall be treated as Cash Election Shares, in each case subject to the allocation rules set forth in Section 1.02(h) of this Agreement.

The Exchange Agent shall use reasonable efforts to make the Election Form available to all persons who become holders of Citizens Common Stock during the period between the record date for the mailing of the Election Form and the Election Deadline. If a holder of Citizens Common Stock: (i) does not submit a properly completed

Election Form before the Election Deadline; (ii) revokes an Election Form prior to the Election Deadline and does not resubmit a properly completed Election Form prior to the Election Deadline; or (iii) fails to perfect his, her or its dissenters’ rights pursuant to Section 1.02(e)(v) of this Agreement, the shares of Citizens Common Stock held by such holder shall be deemed “No Election Shares”. Nominee record holders who hold Citizens Common Stock on behalf of multiple beneficial owners shall be required to indicate how many of the shares held by them are Stock Election Shares, Cash Election Shares and No Election Shares. For purposes of Section 1.02(h), any Dissenting Citizens Shares shall be deemed to be Cash Election Shares, provided that Dissenting Citizens Shares shall not under any circumstance be converted into Reallocated Stock Shares.

(g) Effective Election. Any Election shall be properly made only if the Exchange Agent shall have actually received a properly completed Election Form by the Election Deadline. Any Election Form may be revoked or changed by the person submitting such Election Form to the Exchange Agent by written notice to the Exchange Agent only if such written notice is actually received by the Exchange Agent at or prior to the Election Deadline. The Exchange Agent shall have reasonable discretion to (i) determine whether any Election, modification or revocation is received, (ii) determine whether any Election, modification or revocation has been properly made, and (iii) disregard immaterial defects in any Election Form. Good faith determinations made by the Exchange Agent regarding such matters shall be binding and conclusive. Neither C&N, Citizens nor the Exchange Agent shall be under any obligation to notify any person of any defect in an Election Form.

(h) Allocation. All Elections shall be subject to the following allocation rules. The Exchange Agent shall effect the allocation of the aggregate Merger Consideration among the holders of Citizens Common Stock in accordance with their respective Election Forms, but subject to the following allocation rules:

(i) Aggregate Stock Consideration Overelected. If the number of Stock Election Shares exceeds fifty percent (50%) of the total number of shares of Citizens Common Stock issued and outstanding on the Effective Date, then:

(a) Employee Benefits. Except as set forth in this Section 4.11(a) and as provided in Section 4.11(b), as of the Effective Time, each employee of Citizens or CTC who becomes an employee of C&N or of any C&N Subsidiary shall be entitled to full credit for each year of service with Citizens or CTC for purposes of determining eligibility for participation and vesting, but not benefit accrual, in C&N’s, or as appropriate, in the C&N Subsidiary’s, employee benefit plans, programs and policies. C&N shall use the original date of hire by Citizens or CTC in making these determinations. Notwithstanding the above, Citizens employees shall be eligible to participate in the Citizens & Northern Bank Pension Plan commencing January 1, 2008, provided that they have the requisite service (which includes credited service with Citizens), subject to the provisions of the Citizens & Northern Pension Plan in effect as of January 1, 2008. After the Effective Time, C&N may maintain, discontinue, amend, freeze, convert to, or merge any C&N or C&N Subsidiary plan or any Citizens benefit plan, subject to the plan’s provisions and applicable Law, and subject further to the requirement that employees of Citizens or CTC shall not be treated differently in any material respect than similarly situated employees of C&N or a C&N Subsidiary, except as specifically referenced herein.

(b) Severance Policy. C&N agrees to cause C&N Bank to provide a lump sum severance payment, as set forth below, to any full-time, active employee of Citizens or CTC whose employment is terminated hereafter in connection with the Merger up to twelve (12) months following the Effective Date, because (i) such employee’s position is eliminated, or (ii) such employee is not offered or retained in comparable employment (i.e., a position of generally similar job description or responsibilities with Citizens or CTC) with C&N Bank or any C&N Subsidiary, excluding any employee (i) who has an existing employment or consulting agreement with Citizens or CTC, (ii) who has accepted an offer from C&N of noncomparable employment, (iii) who has been designated to receive a retention bonus in accordance with Section 4.11(d), or (iv) whose employment is terminated for Cause (as defined below), provided such employee executes such documentation as C&N may reasonably require, including C&N’s customary form of release. The severance pay to be provided by C&N Bank under this subsection shall equal one (1) weeks’ pay for each full year of continuous service (determined based on the date of the employee’s commencement of employment with Citizens) with a minimum severance benefit of four (4) weeks’ pay and a maximum severance benefit of twenty-six (26) weeks’ pay. For purposes of this Section 4.11(b), “Cause” shall mean termination because of the employee’s personal dishonesty, misconduct, breach of fiduciary duty involving personal profit, intentional failure to perform stated duties or willful violation of any Law (other than traffic violations or similar offenses). The benefits provided to terminated Citizens employees under this subsection are the only severance benefits payable by C&N or C&N Bank to such employees (excluding severance benefits provided under existing employment or consulting agreements or as otherwise required by Law). The benefits payable to employees under this subsection or otherwise shall in any event be in lieu of any termination benefits to which such employees would otherwise be entitled under C&N’s or C&N Bank’s severance policies or programs then in effect.

(c) Intention regarding Future Employment. C&N shall use its reasonable best efforts to inform the employees of Citizens at least forty-five (45) days prior to the Effective Date of the likelihood of such employees having continued employment with C&N Bank following the Effective Date.

(d) Retention Bonuses. Each employee of Citizens or CTC jointly designated in writing by mutual agreement of C&N and Citizens shall be entitled to receive a “retention” bonus from Citizens, CTC, C&N or a C&N Subsidiary, as the case may be, in an amount to be mutually agreed upon in writing by C&N and Citizens, which amount shall not exceed $7,500 per employee or $25,000 in the aggregate for all employees, in the event that such employee remains an employee of Citizens or CTC, or C&N or a C&N Subsidiary, as applicable, until the Effective Date (or in certain cases, a date, after the Effective Date, that the systems conversion occurs) provided that such employee is not terminated for Cause prior to the Effective Date or thereafter, if applicable. Except as

otherwise agreed to by C&N, retention bonuses shall not be payable to any Citizens or CTC employee who is a party to an employment or other agreement that provides severance benefits or payments in the event of a termination of employment following a change in control of Citizens or CTC.

Section 4.12 —Citizens Division; Advisory Board.

(a) For a period of at least two (2) years after the Effective Date, C&N shall operate the former business of CTC as the Citizens Division of Citizens & Northern Bank, subject to such consolidationsand/or closures of branch offices of C&N and CTC as deemed desirable by C&N (the “Citizens Division”) under the name “Citizens Trust Company, a division of Citizens & Northern Bank” or similar designation authorized by the PDB (and to which the FDIC has no objection).

(b) On the Effective Date, C&N Bank shall establish the Citizens Advisory Board (the “Citizens Advisory Board”), which shall consist of all non-employee members of the CTC board of directors immediately before the Effective Date, but excluding the Citizens Designee. The Citizens Advisory Board shall be maintained for a term of at least two (2) years after the Effective Date. Each member of the Citizens Advisory Board shall be paid for his or her services in accordance with C&N’s standard compensation policy for advisory or divisional board members and shall be subject to C&N’s policies concerning advisory board membership, including mandatory retirement provisions.

Section 4.13 —Affiliate Letter. Citizens shall deliver to C&N, concurrently with the execution of this Agreement, the Letter Agreement attached hereto as Exhibit 2 (the “Letter Agreement”), executed by each director and each executive officer of Citizens.

(2) C&N and Citizens will each be a party to the reorganization within the meaning of Section 368(b) of the IRC;

(3) No gain or loss will be recognized by C&N or Citizens as a result of the Merger (except for amounts resulting from any required change in accounting methods or any income or deferred gain recognized under the relevant consolidated return regulations);

(6) Each Citizens shareholder’s aggregate tax basis in any shares of C&N common stock received in the transaction (including fractional shares deemed received and redeemed) will be the same as the aggregate tax basis of the shares of Citizens common stock the Citizens shareholder surrendered in exchange therefor, decreased by the amount of any cash received by the shareholder and increased by the amount of income or gain recognized by the shareholder in the exchange; and

(7) Each Citizens shareholder’s holding period in any shares of C&N common stock received in the transaction (including any fractional shares deemed received and redeemed) will, in each instance, include the period during which the shares of Citizens common stock surrendered in exchange therefor were held.
