Preferred Stock and dividends accrued thereon to the date of such payment.

FOURTEENTH. BUSINESS COMBINATIONS

A.Voting Requirements for Business Combinations

In addition to any affirmative vote required by law or the Articles, no Business Combination may be effected with an Interested Shareholder for a period of five years following the date that such shareholder became an Interested Shareholder, unless approved by the affirmative vote of the holders of outstanding voting securities of the Corporation entitled to exercise two-thirds of the combined voting power of the Corporation and by the affirmative vote of two-thirds of the voting securities beneficially owned by Disinterested Shareholders.

B. Fair Price Requirement

Within 25 days after a corporation, person or other entity becomes an Interested Shareholder, such Interested Shareholder shall give written notice to each holder of voting securities or securities convertible into or exchangeable for voting securities, or options, warrants or rights to purchase voting securities or securities convertible into or exchangeable for voting securities of the Corporation stating that it is an Interested Shareholder and that such holder may sell any of the above-mentioned securities to the Interested Shareholder for cash at the price, as determined below. Within 25 days after a holder receives the above notice, the holder may send written demand to the Interested Shareholder stating the number, class and identifying number of the securities to be sold to the Interested Shareholder. Within 10 days after the holder sends written demand, the Interested Shareholder must purchase the securities identified in the written demand. Upon expiration of the 10 day purchase period, any holder of securities entitled to written notice under this section may institute an action or proceeding in any court of law or equity to enforce his or her rights under this section.

1.The price for all securities to be purchased by an Interested Shareholder shall be the higher of (a) the highest price paid per security by the Interested Shareholder for the voting securities at any time plus an increment representing any value, including, without limitation, any proportion of any value payable for acquisition of control of the Corporation, that may not be reflected in such price or (b) the highest price per security of the voting securities traded on the securities markets in which the Corporation’s securities are traded during the 45 day period commencing 30 days prior to the date such Interested Shareholder became an Interested Shareholder.

1.For purposes of determining the price, all convertible or exchangeable securities shall be deemed to be converted or exchanged and all options, warrants and rights shall be treated as being exercised. That portion of the price equal to the exercise price for options, warrants and rights shall be paid to the Corporation and the balance to the holders thereof.

2.If an Interested Shareholder does not send notice or purchase securities as required by this section, the Corporation, at its option, may assume the obligations of the Interested Shareholders.

3.Regardless of anything contained in this subsection, in the event any court of law or equity declares an Interested Shareholder’s duty to purchase securities under this section unenforceable, the Corporation shall purchase such securities for cash at the price determined by the application of subsection (1) above.
