(6)(a) Except as set forth in Clause (d) of this paragraph (6) of Article Seventh, the affirmative vote of the holders of at least 75% of the outstanding shares of the corporation entitled to vote in election of Directors shall be required to effect or validate:

(1) any merger or consolidation with or into any other corporation, or

(2) any sale or lease of all or a substantial part of the assets of the corporation to any other corporation, person or other entity,

if, in the case of both (1) and (2), as of the record date for determination of stockholders entitled to notice thereof and to vote thereon, such other corporation, person or entity which is party to such a transaction is the beneficial owner, directly or indirectly, of 5% or more of the outstanding shares of the corporation entitled to vote in elections of directors. Such affirmative vote shall be in addition to any vote of the holders of the shares of the corporation otherwise required by law, this certificate of incorporation or any agreement between the corporation and any national securities exchange.

(4) which are beneficially owned, directly or indirectly (including shares deemed owned through application of clause (2) above), by any other corporation, person or entity with which it or its “affiliate” or “associate” has any agreement or arrangement or understanding for the purpose of acquiring, holding, voting, or disposing of shares of the corporation. For the purpose of determining whether a specific corporation, person or entity is the beneficial owner of one or more of the outstanding shares of the corporation, the outstanding shares of the corporation shall include shares not in fact outstanding but

3

deemed owned through the application of clauses (b)(2)(3) and (4) above by such corporation, person or entity, but shall not include any other shares which may be issuable pursuant to any agreement or upon exercise of conversion rights, warrants or options or otherwise.

(c) The Board of Directors shall have the power and duty to determine for the purposes of this paragraph (6), on the basis of information known to the corporation, whether:

(1) such other corporation or entity beneficially owns more than 5% of the outstanding shares of the corporation entitled to vote in elections of Directors;

(2) a corporation, person, or entity is an “affiliate” or “associate” (as defined in paragraph (b) above) of another; and

(3) the memorandum of understanding referred to in clause (d) below is substantially consistent with the transaction covered thereby.

Any such determination shall be conclusive and binding for all purposes of this paragraph (6).

(d) The provisions of this paragraph (6) shall not apply to:

(1) any transaction of a type addressed by paragraph 6(a)(1) or (2) if the Board of Directors of the corporation has approved a memorandum of understanding or other written agreement providing for such transaction with such other corporation prior to the time that such other corporation shall have become the beneficial owner of more than 5% of the outstanding shares of the corporation entitled to vote in elections of Directors; or after such acquisition of 5% of the outstanding shares, if 75% or more of the entire Board of Directors approve such transaction prior to its consummation; or

(2) any merger or consolidation of the corporation with, or any sale or lease by the corporation or any subsidiary thereof of any assets of, or any sale or lease by the corporation or any subsidiary thereof of any of its assets to, any corporation of which a majority of the outstanding shares of all classes of stock entitled to vote in election of Directors is owned of record or beneficially by the corporation and its subsidiaries.

NINTH. No action required to be taken or which may be taken at any annual or special meeting of stockholders of the corporation may be taken without a meeting, and the power of stockholders to consent in writing, without a meeting, to the taking of any action is specifically denied.

TENTH. (1) The corporation shall indemnify its officers, directors, employees and agents to the fullest extent permitted by law.

(2) No director of the corporation shall be personally liable to the corporation or its stockholders for monetary damages, for breach of fiduciary duty as a director, except for liability (i) for any breach of the director’s duty of loyalty to the corporation or its stockholders; (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law; (iii) under Section 174 of the Delaware General Corporation Law; or (iv) for any transaction from which the director derived an improper personal benefit.

Whenever a compromise or arrangement is proposed between this corporation and its creditors or any class of them and/or between this corporation and its stockholders or any class of them, any court of equitable jurisdiction within the State of Delaware may, on this application in a summary way of this corporation or of any creditor or stockholder thereof, or on the application of any receiver or receivers appointed for this corporation under the provisions of Section 291 of Title 8 of the Delaware Code or on the application of trustees in dissolution or of any receiver or receivers appointed for this corporation under the provisions of Section 279 of Title 8 of the Delaware Code order a meeting of the creditors or class of creditors, and/or of the

4

stockholders or class of stockholders of this corporation, as the case may be, to be summoned in such manner as the said court directs. If a majority in number representing three-fourths in value of the creditors or class of creditors, and/or of the stockholders or class of stockholders of this corporation, as the case may be, agree to any compromise or arrangement and to any reorganization of this corporation as consequence of such compromise or arrangement, the said compromise or arrangement and the said application has been made, be binding on all the creditors or class of creditors, and/or on all the stockholders or class of stockholders, of this corporation, as the case may be, and also on this corporation.
