Whenever an amendment to or restatement of these Articles of Organization or a sale, lease or exchange by the corporation of any of its assets, or a merger or consolidation involving the corporation, or the dissolution of the corporation is required by law to be approved by the stockholders, such action shall be properly authorized if approved by a majority of the shares outstanding and entitled to vote thereon.

CONTINUATION SHEET 6B

disposition of or otherwise in connection with or resulting from any action, suit or other proceeding, whether civil, criminal, administrative or investigative, before any court or administrative or legislative or investigative body, in which he may be or may have been involved as a party or otherwise or with which he may be or may have been threatened, while in office or thereafter, by reason of his being or having been such a director, officer, employee, agent or trustee, or by reason of any action taken or not taken in any such capacity, except with respect to any matter as to which he shall have been finally adjudicated by a court of competent jurisdiction not to have acted in good faith in the reasonable belief that his action was in the best interests of the corporation. Expenses, including but not limited to counsel fees and disbursements, so incurred by any such person in defending any such action, suit or proceeding may be paid from time to time by the corporation in advance of the final disposition of such action, suit or proceeding upon receipt of an undertaking by or on behalf of the person indemnified to repay the amounts so paid if it shall ultimately be determined that indemnification of such expenses is not authorized hereunder.

As to any matter disposed of by settlement by any such person, pursuant to a consent decree or otherwise, no such indemnification either for the amount of such settlement or for any other expenses shall be provided unless such settlement shall be approved as in the best interests of the corporation, after notice that it involves such indemnification, (a) by a vote of a majority of the disinterested directors then in office (even though the disinterested directors be less than a quorum), or (b) by any disinterested person or persons to whom the question may be referred by vote of a majority of such disinterested directors, or (c) by vote of the holders of a majority of the outstanding stock at the time entitled to vote for directors, voting as a single class, exclusive of any stock owned by any interested persons, or (d) by any disinterested person or persons to whom the question may be referred by vote of the holders of a majority of such stock. No such approval shall prevent the recovery from any such officer, director, employee, agent or trustee of any amounts paid to him or on his behalf as indemnification in accordance with the preceding sentence if such person is subsequently adjudicated by a court of competent jurisdiction not to have acted in good faith in the reasonable belief that his action was in the best interests of the corporation.

The right of indemnification hereby provided shall not be exclusive of or affect any other rights to which any director, officer, employee, agent, or trustee may be entitled or which may lawfully be granted to him. As used herein, the terms “director,” “officer,” “employee,” “agent” and “trustee” include their respective executors, administrators and other legal representatives,

CONTINUATION SHEET 6C

and “interested” person is one against whom the action, suit or other proceeding in question or another action, suit or other proceeding on the same or similar grounds is then or had been pending or threatened, and a “disinterested” person is a person against whom no such action, suit or other proceeding is then or had been pending or threatened.

By action of the board of directors, notwithstanding any interest of the directors in such action, the corporation may purchase and maintain insurance, in such amounts as the board of directors may from time to time deem appropriate, on behalf of any person who is or was a director, officer, employee or other agent of the corporation, or is or was serving at the request of the corporation as a director, trustee, officer, employee or other agent of another organization in which it directly or indirectly owns shares or of which it is directly or indirectly a creditor, against any liability incurred by him in any such capacity, or arising out of his status as such, whether or not the corporation would have the power to indemnify him against such liability.

Intercompany Transactions

No contract or transaction between the corporation and one or more of its directors or officers, or between the corporation and any other organization of which one or more of its directors or officers are directors, trustees or officers, or in which any of them has any financial or other interest, shall be void or voidable, or in any way affected, solely for this reason, or solely because the director or officer is present at or participates in the meeting of the board of directors or committee thereof which authorizes, approves or ratifies the contract or transaction, or solely because his or their votes are counted for such purposes, if:

(a) The material facts as to his relationship or interest and as to the contract or transaction are disclosed or are known to the board of directors or the committee which authorizes, approves or ratifies the contract or transaction, and the board or committee in good faith authorizes, approves or ratifies the contract or transaction by the affirmative vote of a majority of the disinterested directors, even though the disinterested directors be less than a quorum; or

(b) The material facts as to his relationship or interest and as to the contract or transaction are disclosed or are known to the stockholders entitled to vote thereon,

CONTINUATION SHEET 6D

and the contract or transaction is specifically authorized, approved or ratified in good faith by vote of the stockholders; or

(c) The contract or transaction is fair as to the corporation as of the time it is authorized, approved or ratified by the board of directors, a committee thereof, or the stockholders.

Common or interested directors may be counted in determining the presence of a quorum at a meeting of the board of directors or of a committee thereof which authorizes, approves or ratifies the contract or transaction. No director or officer of the corporation shall be liable or accountable to the corporation or to any of its stockholders or creditors or to any other person, either for any loss to the corporation or to any other person or for any gains or profits realized by such director or officer, by reason of any contract or transaction as to which clauses (a), (b) or (c) above are applicable.
