D. Any reclassification of securities, recapitalization, reorganization of this corporation or any merger or consolidation of this corporation with any of its Subsidiaries, or any similar transaction which has the effect, directly or indirectly, of increasing the proportionate share of the outstanding capital stock beneficially owned by any 20% Shareholder or the proportionate number of votes which may be cast in an election of directors in respect of the shares of this corporation’s capital stock beneficially owned by any 20% Shareholder; or

If such 20% Shareholder or any Affiliate of such 20%

2

Shareholder has acquired shares other than for cash, the price at which such shares shall be deemed to have been acquired shall be determined by the Continuing Directors of this corporation and such determination of a majority of such Continuing Directors of this corporation shall be conclusive for the purposes of this Article 6:

provided however, that no transaction described in Subparagraphs A through F above shall constitute a Business Combination:

(i) if the Board of Directors has by resolution authorized or ratified the execution and delivery of a written agreement in principle, memorandum of understanding, letter of intent, agreement or plan respecting such transaction prior to the time that any 20% Shareholder involved in such transaction acquired beneficial ownership of more than 10% of the outstanding shares of any class or series of any capital stock of this corporation, or

(ii) if 70% of the Continuing Directors have approved the transaction prior to its submission to the shareholders.

No Business Combination described in Subparagraphs A through E above shall be entered into by this corporation without the affirmative vote of the holders of at least 80% of the outstanding shares of all classes and series of this corporation’s capital stock, voting as a single class, and the affirmative vote of the holders of at least 66  ²/3% of all shares of this corporation’s capital stock, other than the shares beneficially owned by the 20% Shareholder and no Business Combination described in Subparagraph F above shall be entered into by this corporation without the affirmative vote of the holders of at least 85% of the outstanding shares of all classes and series of this corporation’s capital stock, voting as a single class, and the affirmative vote of the holders of at least 75% of all shares of this corporation’s capital stock other than the shares beneficially owned by the 20% Shareholder.

3

owned by such 10% Shareholder and the Affiliates of such 10% Shareholder that such shares so held by such 10% Shareholder and his Affiliates represent as a proportion of the outstanding shares of the class being tendered for by the corporation. The corporation is hereby specifically authorized to set appropriate conditions to any tender offer made by it limiting the shares to be tendered by 10% Shareholders and their Affiliates and/or the shares which the corporation is required to accept from 10% Shareholders and their Affiliates in any tender offer to such percentages of the shares beneficially owned by 10% Shareholder and their Affiliates as the Board of Directors deems to be in the best interests of the corporation, provided, however, that the provisions of this paragraph shall not apply to purchases by this corporation of its own capital stock on the over-the-counter market or on any exchange other than purchases effected on such markets in a “cross” transaction or by prearrangement, with a 10% Shareholder or an Affiliate of a 10% Shareholder.
