Unless required by statute, or determined by the chairman of the meeting to be advisable, the vote on any question need not be by written ballot. On a vote by written ballot, each ballot shall be signed by the stockholder voting, or by his proxy, if there be such proxy, and shall state the number of shares voted.

Section 9. List of Stockholders. The officer who has charge of the stock ledger of the Corporation shall prepare and make, at least ten days before every meeting of stockholders, a complete list of the stockholders entitled to vote at the meeting, arranged in alphabetical order, and showing the address of each stockholder and the number of shares registered in the name of each stockholder.

Any action which is required to be or may be taken at any annual or special meeting of stockholders of the Corporation may be taken without a meeting, without prior notice to stockholders and without a vote if consents in writing, setting forth the action so taken, shall have been signed by the holders of outstanding stock having not less than the minimum number of votes that would be necessary to authorize or to take such action at a meeting at which all shares entitled to vote thereon were present and voted.

Section 11. Duration and Revocation of Consents.

Section 12. Notice of Action by Consent. The Corporation shall give prompt notice of the taking of corporate action without a meeting by less than unanimous written consent to stockholders who have not consented in writing and who, if the action had been taken at a meeting, would have been entitled to notice of the meeting if the record date for such meeting had been the date that written consents signed by a sufficient number of stockholders to take the action were delivered to the Corporation in the manner provided in Section 228(c) of the Delaware General Corporation Law.

If there are no directors in office, then an election of directors may be held in the manner provided by statute. If, at the time of filling any vacancy or any newly created directorship, the directors then in office shall constitute less than a majority of the whole Board (as constituted immediately prior to any such increase), the Court of Chancery may, upon application of any stockholder or holders of at least ten percent of the votes of the shares at the time outstanding having the right to vote for such directors, summarily order an election to be held to fill any such vacancies or newly created directorships, or to replace the directors chosen by the directors then in office. Except as otherwise provided in these By-Laws, when one or more directors shall resign from the Board of Directors, effective at a future date, a majority of the directors then in office, including those who have so resigned, shall have the power to fill such vacancy or vacancies, the vote thereon to take effect when such resignation or resignations shall become effective, and each director so chosen shall hold office as provided in this section in the filling of other vacancies.

Except as otherwise provided in the Certificate of Incorporation or in these By-Laws, any director may be removed, either with or without cause, at any time, by the affirmative vote of a majority of the votes of the issued and outstanding stock entitled to vote for the election of directors of the Corporation given at a special meeting of the stockholders called and held for the purpose; and the vacancy in the Board of Directors caused by any such removal may be filled by such stockholders at such meeting, or, if the stockholders shall fail to fill such vacancy, as in these By-Laws provided.

Section 13. Compensation.

Section 14. Action Without Meeting.

INDEMNIFICATION

To the fullest extent permitted by law, the Corporation shall indemnify any director or officer of the Corporation who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative by reason of the fact that he is or was a director or officer of the Corporation, or is or was serving at the request of the Corporation as a director, officer, agent or employee of another corporation, partnership, joint venture, trust or other enterprise against expenses (including attorneys’ fees), liability, loss, judgment, fines and amounts paid in settlement actually and reasonably incurred by him in connection with such action, suit or proceeding if he acted in good faith and in a manner reasonably believed to be in or not opposed to the best interests of the Corporation, and, with respect to any criminal action or proceedings, had no reasonable cause to believe his conduct was unlawful. The termination of any action, upon a plea of nolo contendere or equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner which be reasonably believed to be in or not opposed to the best interests of the Corporation, and, with respect of any criminal action or proceeding, had reasonable cause to believe that his conduct was unlawful.

Such indemnity shall inure to the benefit of the heirs, executors and administrators of any director or officer so indemnified pursuant to this Article. The right to indemnification under this Article shall be a contract right and shall include the right to be paid by the Corporation the expenses incurred in defending any such proceeding in advance of its disposition; provided however, that, if the Delaware General Corporation Law requires, the payment of such expenses incurred in advance of the final disposition of a proceeding shall be made only upon delivery to the Corporation of an undertaking, by or on behalf of such director or officer to repay all amounts so advanced if it shall ultimately be determined that such director or officer is not entitled to be indemnified under this Article or otherwise. Such indemnification and advancement of expenses shall be in addition to any other rights to which those directors and officers seeking indemnification and advancement of expenses may be entitled under any law, agreement, vote of stockholders, or otherwise.

Any repeal or amendment of this Article by the stockholders of the Corporation or by changes in applicable law shall, to the extent permitted by applicable law, be prospective only, and shall not adversely affect any right to indemnification or advancement of expenses of a

director or officer of the Corporation existing at the time of such repeal or amendment. In addition to the foregoing, the right to indemnification and advancement of expenses shall be to the fullest extent permitted by the General Corporation Law of the State of Delaware or any other applicable law and all amendments to such laws as hereafter enacted from time to time.

ARTICLE VI

STOCK

Section 1. Certificates. Every holder of stock shall be entitled to have a certificate signed by or in the name of the Corporation by the Chairman of the Board of Directors, if any, or the President, and by the Secretary or an Assistant Secretary, of the Corporation, certifying the number of shares owned by him in the Corporation. Any of or all the signatures on the certificate may be a facsimile. In case any officer, transfer agent, or registrar who has signed or whose facsimile signature has been placed upon a certificate shall have ceased to be such officer, transfer agent, or registrar before such certificate is issued, it may be issued by the Corporation with the same effect as if he were such officer, transfer agent, or registrar at the date of issue.

The Corporation may issue a new certificate of stock in the place of any certificate theretofore issued by it, alleged to have been lost, stolen or destroyed, and the Corporation may require the owner of the lost, stolen or destroyed certificate, or his legal representative, to give the Corporation a bond sufficient to indemnify it against any claim that may be made against it on account of the alleged loss, theft or destruction of any such certificate or the issuance of such new certificate.

Section 3. Waiver of Notice of Meetings of Stockholders, Directors and Committees. Any written waiver of notice, signed by the person entitled to notice, whether before or after the time stated therein, shall be deemed equivalent to notice. Attendance of a person at a meeting shall constitute a waiver of notice of such meeting, except when the person attends a meeting for the express purpose of objecting, at the beginning of the meeting, to the transaction of any business because the meeting is not lawfully called or convened. Neither the business to be transacted at, nor the purpose of any regular or special meeting of the stockholders, directors, or members of a committee of directors need be specified in any written waiver of notice.

Section 4. Interested Directors; Quorum. No contract or transaction between the Corporation and one or more of its directors or officers, or between the Corporation and any other Corporation, partnership, association, or other organization in which one or more of its directors or officers are directors or officers, or have a financial interest, shall be void or voidable 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 the contract or transaction, or solely because his or their votes are counted for such purpose, if (1) 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, and the Board of Directors or committee in good faith authorizes the contract or transaction by the affirmative votes of a majority of the disinterested directors, even though the disinterested directors be less than a quorum; or (2) 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, and the contract or transaction is specifically approved in good faith by vote of the stockholders; or (3) 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 thereat 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 which authorizes the contract or transaction.

Section 5. Form of Records. Any records maintained by the Corporation in the regular course of its business, including its stock ledger, books of account, and minute books, may be kept on, or be in the form of, punch cards, magnetic tape, photographs, microphotographs, or any other information storage device, provided that the records so kept can be converted into clearly legible form within a reasonable time. The Corporation shall so convert any records so kept upon the request of any person entitled to inspect the same.

Section 6. Amendments. These By-Laws may be amended or repealed, or new By-Laws may be adopted, (1) at any annual or special meeting of the stockholders, by a majority of the total votes of the stockholders, present or in person or represented by proxy and entitled to vote on such action; provided, however, that the notice of such meeting shall have been given as provided in these By-Laws, which notice shall mention that amendment or repeal of these By-Laws, or the adoption of new By-Laws, is one of the purposes of such meeting; (2) by written consent of the stockholders pursuant to Section 11 of Article I; or (3) by action of the Board of Directors.
