(f) Other Transactions. Any other transaction or series of transactions that is similar in purpose or effect to those referred to in clauses (a) through (e) of this paragraph 1.

This voting requirement shall apply even though no vote, or a lesser percentage vote, may be required by law, by any other provision of these Articles of Incorporation, or otherwise. The term “business combination”, as used in this Article, means any of the transactions referred to in clauses (a) through (f) of this paragraph 1.

2. Fair Price Requirement. The fair price requirement will be satisfied if the consideration to be received in the business combination by the holders of the Corporation’s Common Shares and Preferred Shares, and by the Corporation or any of its subsidiaries, as the case may be, meets the following tests:

(a) Amount of Consideration to Be Received by Shareholders. If any holder of the Corporation’s Common Shares or Preferred Shares, other than an interested shareholder, is to receive consideration in the business combination for any of the shares, the aggregate amount of cash and fair market value of any other consideration to be received per share may not be less than the sum of —.

(A) the greater of (i) the highest per share price, including commissions, paid by the interested shareholder for any shares of the same class or series during the two-year period ending on the date of the most recent purchase by the interested shareholder of any such shares, (ii) the highest sales price reported for shares of the same

class or series traded on a national securities exchange or in the over-the-counter market during the one year period preceding the first public announcement of the proposed business transaction, or (iii) in the case of Preferred Shares, the amount of the per share liquidation preference; plus

(B) interest on the per share price calculated at the prime rate for unsecured short-term loans in effect at AmeriTrust Company, Cleveland, Ohio, on the date on which the interested shareholder first became an interested shareholder, compounded annually from that date until the business combination is consummated, less the per share amount of cash dividends payable to holders of record on record dates in the interim, up to the amount of such interest.

For purposes of this clause (a), per share amounts will be adjusted for any stock dividend, stock split, or similar transaction.

(b) Form of Consideration to Be Received by Shareholders. The consideration to be received by holders of the Corporation’s Common Shares or Preferred Shares must be in cash or in the same form as was previously paid by the interested shareholder for shares of the same class or series; if the interested shareholder previously paid for such shares with different forms of consideration, the consideration to be received by the holders of the shares must be in cash or in the same form as was previously paid by the interested shareholder for the largest number of shares previously acquired by it. The provisions of this clause (b) are not intended to diminish the aggregate amount of cash and fair market value of any other consideration that any holder of the Corporation’s Common Shares or Preferred Shares is otherwise entitled to receive upon the liquidation or dissolution of the Corporation, under the terms of any contract with the Corporation or an interested shareholder, or otherwise.

(c) Consideration to Be Received by the Corporation or Any of Its Subsidiaries. If the Corporation or any of its subsidiaries is to

receive consideration in the business combination, the consideration to be received must be fair to the Corporation or its subsidiaries, as determined by the continuing directors (as hereinafter defined).

3. Other Conditions. The other conditions will be satisfied if, from the time the interested shareholder became an interested shareholder until the completion of the business combination, each of the following has at all times been and continues to be true:

(a) Continuing Directors. The Corporation’s Board of Directors has included at least five continuing directors. The term “continuing director”, as used in this Article, means an individual who (i) either was a director of the Corporation at the time the interested shareholder became an interested shareholder or was subsequently nominated or elected by the other continuing directors and (ii) is not an affiliate or associate (as hereinafter defined) of the interested shareholder. All actions required or permitted to be taken by the continuing directors under this Article shall be taken by the unanimous written consent of all continuing directors or by the vote of a majority of the continuing directors at a meeting convened upon such notice as would be required for a meeting of the full Board of Directors.

(b) No Acquisition of Additional Shares. The interested shareholder has not become the beneficial owner (as hereinafter defined) of any additional Common Shares or Preferred Shares of the Corporation, except (i) as part of the transaction that resulted in the interested shareholder becoming an interested shareholder, (ii) upon conversion of securities previously acquired by it, or (iii) pursuant to a stock dividend or stock split.

(c) No Special Benefits to the Interested Shareholder. The interested shareholder has not received, directly or indirectly, the benefit (except proportionately as a shareholder) of any loan, advance, guaranty, pledge, or other financial assistance, tax credit or deduction, or other benefit from the Corporation or any of its subsidiaries.

(d) Proxy Statement. A proxy or information statement describing the business combination and complying with the requirements of the Securities Exchange Act of 1934, as amended, and the rules and regulations under it (or any subsequent provisions replacing that Act and the rules and regulations under it) has been mailed at least 30 days prior to the completion of the business combination to the holders of all outstanding shares of the Corporation entitled to vote in elections of directors, whether or not shareholder approval of the business combination is required. If deemed advisable by the continuing directors, the proxy or information statement shall contain a recommendation by the continuing directors as to the advisability (or inadvisability) of the business combination and/or an opinion by an investment banking firm, selected by the continuing directors and retained at the expense of the Corporation, as to the fairness (or unfairness) of the business combination to holders of the Corporation’s Common Shares or Preferred Shares other than the interested shareholder.

(e) No Omission or Reduction of Dividends. Except to the extent approved by the continuing directors, there has been no (i) failure to pay in full, when and as due, any dividends on the Corporation’s Preferred Shares or (ii) failure to pay or reduction in the annual rate of dividends on the Corporation’s Common Shares, whether directly or indirectly through a reclassification, recapitalization, or otherwise.

(f) No Change in Business or Capital Structure. Except to the extent approved by the continuing directors, there has been no material change in (i) the nature of the business conducted by the Corporation and its subsidiaries or (ii) the capital structure of the Corporation, including but not limited to any change in the number of outstanding Common Shares, the number and series of any outstanding Preferred Shares, and the types and aggregate principal amount of any outstanding debt securities, except for changes resulting from the exercise of previously issued options, warrants, or other rights, the conversion of previously issued shares, the issuance of previously authorized debt securities,

and the mandatory redemption or retirement of debt securities in accordance with their terms.
