Each shareholder shall have one vote for each share of stock having voting power, registered in his name on the books of the corporation.

The Board of Directors shall consist of not less than five (5) and not more than nine (9) members, the precise number to be fixed by resolution of the Board of Directors from time to time.

The Directors may fill the place of any Director which may become vacant prior to the expiration of his term by a vote of the majority of remaining Directors though the remaining Directors may be less than a quorum of the Board of Directors; such appointment by the Directors shall continue until the expiration of the term of the Director whose place has become vacant. Any vacancy which occurs by reason of any increase in the number of Directors shall be filled by election at an annual meeting or special meeting of shareholders called for such a purpose. 3.4 Election of Directors. Directors shall be elected annually, at the annual meeting of shareholders and shall serve until the next annual meeting of shareholders and until their successors have been elected and qualified. 3.5 Removal. A Director may be removed from office, with or without cause, upon the majority vote of the shareholders entitled to vote at an election of Directors, at a meeting with respect to which notice of such purpose is given.

Any Director may resign at any time either orally at any meeting of the Board of Directors or by so advising to a Co-Chairman of the Board, if any, or the Chief Executive Officer or President or by giving written notice to the corporation. A Director who resigns may postpone the effectiveness of his resignation to a future date or upon the occurrence of a future event specified in a written tender of resignation. If no time of effectiveness is specified therein, a resignation shall be effective upon tender.

The Executive Committee may fix its own rules of procedures, including provision for notice of its meetings. It shall keep a record of its proceedings and shall report these proceedings to the Board of Directors at the meeting thereof held next after they have been taken, and all such proceedings shall be subject to revision or alteration by the Board of Directors except to the extent that action shall have been taken pursuant to or in reliance upon such proceedings prior to any such revision or alteration. (d) The Executive Committee shall act by majority vote of its members; provided, that contracts or transactions of and by the corporation in which officers or Directors of the corporation are interested shall require the affirmative vote of a majority of the disinterested members of the Executive Committee, at a meeting of the Executive Committee at which the material facts as to the interest and as to the contract or transaction are disclosed or known to the members of the Executive Committee prior to the vote. (e) Members of the Executive Committee may participate in committee proceedings by means of conference telephone or similar communications equipment by means of which all persons participating in the proceedings can hear each other, and such participation shall constitute presence in person at such proceedings.

At all meetings of the Board of Directors, the presence of one-third of the Directors, but not less than two Directors, shall be necessary and sufficient to constitute a quorum for the transaction of business. Directors may participate in any meeting by means of conference telephone or similar communications equipment by which all persons participating in the meeting can hear each other, and participation in a meeting by means of such communications equipment shall constitute the presence in person at such meeting. The act of a majority of the Directors present at any meeting at which there is a quorum shall be the act of the Board of Directors, except as may be otherwise specifically provided by- law, the certificate of incorporation or these by-laws. In the absence of a quorum a majority of the Directors present at any meeting may adjourn the meeting from time to time until a quorum is present. Notice of any adjourned meeting need only be given by announcement at the meeting at which the adjournment is taken. 5.6 Action in Lieu of Meeting. Any action required or permitted to be taken at any meeting of the Board of Directors or of any committee thereof may be taken without a meeting if a written consent thereto is signed by all members of the Board of Directors or of such committee, as the case may be, and such written consent is filed with the minutes of the proceedings of the Board of Directors and any further requirements of law pertaining to such consents have been complied with. 5.7 Interested Directors and Officers. An interested Director or officer is one who is a party to a contract or transaction with the corporation or who is an officer or Director of, or has a financial interest in, another corporation, partnership or association which is a party to a contract or transaction with the corporation. Contracts and transactions between the corporation and one or more interested Directors or officers shall not be void or voidable solely because of such relationship or interest or because such a Director is present at a meeting of the Board of Directors or a committee thereof which authorizes, approves or ratifies such contract or transaction, if either: (1) the contract or transaction is approved in good faith by the Board of Directors or appropriate committee by the affirmative votes or consent of a majority of disinterested Directors at a meeting of the Board or committee at which the material facts as to the interested person or persons and the contract or transaction are disclosed or known to the Board or committee prior to the vote; or (2) the contract or transaction is approved in good faith by the shareholders after the material facts as to the interested person or persons and the contract or transaction have been disclosed to them; 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 or the appropriate committee, or the shareholders. Interested Directors may not be counted in determining the presence of a quorum at a meeting of the Board or committee which authorizes the contract or transaction.

The compensation of officers, agents, and employees elected by the Board of Directors shall be fixed by the Board of Directors, but this power may be delegated to any officer, agent or employee as to persons under his direction or control.

He shall have all such powers and duties as generally are incident to the position of Treasurer or as may be assigned to him by the Chief Executive Officer, President or by the Board of Directors. 6.6 Appointment, Powers and Duties of Assistant Secretaries. Assistant Secretaries may be appointed by the Chief Executive Officer, President or elected by the Board of Directors. In the absence or inability of the Secretary to act, any Assistant Secretary may perform all the duties and exercise all the powers of the Secretary.

In such latter event such new officer shall serve until the next annual election of officers. ARTICLE SEVEN CAPITAL STOCK 7.1 Certificates. The interest of each shareholder shall be evidenced by a certificate or certificates representing shares of the corporation which shall be in such form as the Board of Directors may from time to time adopt and shall be numbered and shall be entered in the books of the corporation as they are issued. Each certificate representing shares shall set forth upon the face thereof the following: (a) the name of this corporation; (b) that the corporation is organized under the laws of the State of Delaware; (c) the name or names of the person or persons to whom the certificate is issued; (d) the number and class of shares, and the designation of the series, if any, which the certificate represents; (e) the par value of each share represented by such certificate, or a statement that the shares are without par value; and (f) if any shares represented by the certificate are non-voting shares, a statement or notation to that effect; and if the shares represented by the certificate are subordinate to shares of any other class or series with respect to dividends or amounts payable on liquidation, shall further set forth on either the face or back of the certificate a clear and concise statement to that effect. Each certificate shall be signed by the Chief Executive Officer, President or any Executive or Senior dice President and the Secretary or an Assistant Secretary and may be sealed with the seal of the corporation or a facsimile thereof. If a certificate is countersigned by a transfer agent or registered by a registrar, other than the corporation itself or an employee of the corporation, the signature of any such officer of the corporation may be a facsimile. In case any officer or officers who shall have signed, or whose facsimile signature or signatures shall have been used on, any such certificate or certificates shall cease to be such officer or officers of the corporation, whether because of death, resignation or otherwise, before such certificate or certificates shall have been delivered by the corporation, such certificate or certificates may nevertheless be delivered as though the person or persons who signed such certificate or certificates or whose facsimile signatures shall have been used thereon had not ceased to be such officer or officers. 7.2 Shareholder List. The corporation shall keep or cause to be kept a record of the shareholders of the corporation which readily shows, in alphabetical order or by alphabetical index, and by classes or series of stock, if any, the names of the shareholders entitled to vote, with the address of and the number of shares held by each. Said record shall be presented and kept open for ten days prior to and during all meetings of the shareholders in accordance with the provisions of Section 2.8 of these by-laws. 7.3 Transfer of Shares.

(a) For the purpose of determining shareholders entitled to notice of or to vote at any meeting of shareholders or any adjournment thereof, or entitled to receive payment of any dividend, or in order to make a determination of shareholders for any other proper purpose, the Board of Directors may provide that the stock transfer books shall be closed for a stated period but not to exceed sixty days. If the stock transfer books shall be closed for the purpose of determining shareholders entitled to notice of or to vote at a meeting of shareholders, such books shall be closed for at least ten days immediately preceding such meeting. (b) In lieu of closing the stock transfer books, the Board of Directors may fix in advance a date as the record date for any such determination of shareholders, such date to be not more than sixty days and, in case of a meeting of shareholders, not less than ten days, prior to the date on which the particular action requiring such determination of shareholders is to be taken. 7.5 Registered Owner.

The corporation may, when and if authorized so to do by its Board of Directors, issue certificates for fractional shares or scrip in order to effect share transfers, share distributions or reclassifications, mergers, consolidations or reorganizations. Holders of fractional shares shall be entitled, in proportion to their fractional holdings, to exercise voting rights, receive dividends and participate in any of the assets of the corporation in the event of liquidation. Holders of scrip shall not, unless expressly authorized by the Board of Directors, be entitled to exercise any rights of a shareholder of the corporation, including voting rights, dividend rights or the right to participate in any assets of the corporation in the event of liquidation. In lieu of issuing fractional shares or scrip, the corporation may pay in cash the fair value of fractional interest as determined by the Board of Directors; and the Board of Directors may adopt resolutions regarding rights with respect to fractional shares or scrip as it may deem appropriate, including without limitation the right for persons entitled to receive fractional shares to sell such fractional shares or purchase such additional fractional shares as may be needed to acquire one full share, or sell such fractional shares or scrip for the account of such persons.

Such demand shall be sent to the attention of the Secretary of the corporation at its principal place of business. If the demand is made by an agent or attorney, such demand shall be accompanied by a power of attorney or other authorization to act on behalf of the shareholder. If the Secretary or a majority of the Board of Directors or members of the Executive Committee of the corporation find the request proper, the Secretary shall notify the shareholder within a reasonable time after receipt of said request of the time, which shall in no event be more than thirty days after such notification, and place at which the inspection may be conducted.

ARTICLE NINE INDEMNIFICATION 9.1 Third Party Claims. Under the circumstances prescribed in Sections 9.3 and 9.4, the corporation shall indemnify and hold harmless any person 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, including appeals, (other than an action by or in the right of the corporation) by reason of the fact that he is or was a Director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a Director, officer, partner, employee, or agent of another corporation, partnership, joint venture, trust or other enterprise, against expenses (including attorneys' fees), judgments, fines and amount paid in settlement actually and reasonably incurred by him in connection with such claim, action, suit or proceeding if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interest of the corporation, and with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. The termination of any claim, action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner which he reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal action or proceeding, had reasonable cause to believe that his conduct was unlawful. 9.2 Corporate Claims . Under the circumstances prescribed in Sections 9.3 and 9.4, the corporation shall indemnify and hold harmless any person who was or is a party or is threatened to be made a party to any threatened, pending or completed claim, action or suit by or in the right of the corporation to procure a judgment in its favor by reason of the fact he is or was a Director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a Director, officer, partner, employee or agent, of another corporation, partnership, joint venture, trust or other enterprise against expenses (including attorneys' fees) actually and reasonably incurred by him in connection with the defense or settlement of such action or suit if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation; except that no indemnification shall be made in respect to any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation, unless and only to the extent that the Chancery Court or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Chancery Court or such other court shall deem proper. 9.3 Indemnification of Expenses Where Successful. To the extent that a Director, officer, employee or agent of a corporation has been successful on the merits or otherwise in defense of any action, suit or proceeding referred to in Sections 9.1 and 9.2, or in defense of any claim, issue or matter therein, he shall be indemnified against expenses (including attorneys' fees) actually and reasonably incurred by him in connection therewith. 9.4 Authorization of Indemnification. Except as provided in Section 9.3 and except as may be ordered by a court, any indemnification under Sections 9.1 and 9.2 shall be made by the corporation only as authorized in the specific case upon a determination that indemnification of the director, officer, employee or agent is proper in the circumstances because he has met the applicable standard of conduct set forth in Sections 9.1 and 9.2. Such a determination shall be made (1) by the Board of Directors by a majority vote of a quorum consisting of Directors who were not parties to or have been wholly successful on the merits or otherwise with respect to such action, suit or proceeding, or (2) if such a quorum is not obtainable or, even if obtainable, a quorum of disinterested Directors so directs, by independent legal counsel in a written opinion, or (3) by the affirmative vote of a majority of the shares entitled to vote thereon. 9.5 Advancement of Expenses. Expenses (including attorneys' fees) incurred in defending a civil or criminal action, suit or proceeding may be paid by the corporation in advance of the final disposition of such action, suit or proceeding as authorized by the Board of Directors in the specific case upon receipt of an undertaking by or on behalf of the Director, officer, employee or agent to repay such amount if it shall ultimately be determined that he is not entitled to be indemnified by the corporation as authorized in this Article Nine. 9.6 Nonexclusive Method of Indemnification. The indemnification and advancement of expenses provided by this Article Nine shall not be deemed exclusive of any other rights, in respect of indemnification or otherwise, to which those seeking indemnification or advancement of expenses may be entitled under any agreement, by-law or resolution approved by the affirmative vote of the holders of a majority of the shares entitled to vote thereon taken at a meeting the notice of which specified that such by- law or resolution would be placed before the shareholders, both as to action by a Director, officer, employee or agent in his official capacity and as to action in another capacity while holding such office or position, and shall continue as to a person who has ceased to be a Director, officer, employee or agent and shall inure to the benefit of the heirs, executors and administrators of such a person. 9.7 Insurance. The corporation may purchase and maintain insurance on behalf of any person who is or was a Director, officer, employee or agent of the corporation, or is or was serving at the request of the corporation as a Director, officer, partner, employee or agent of another corporation, partnership, joint venture, trust or other enterprise, against any liability asserted against him and 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 under the provisions of this Article Nine. 9.8 Notification to Shareholders of Indemnification. If any expenses or other amounts are paid by way of indemnification, otherwise than by court order or action by the shareholders or by an insurance carrier pursuant to insurance maintained by the corporation, the corporation shall, not later than the next annual meeting of shareholders unless such meeting is held within three months from the date of such payment, and, in any event, within I5 months from the date of such payment, send by first class mail to its shareholders of record at the time entitled to vote for the election of Directors a statement specifying the persons paid, the amounts paid, and the nature and status at the time of such payment of the litigation or threatened litigation.

Except as otherwise provided in these by-laws, when any notice whatever is required to be given by law, by the certificate of incorporation or by these by-laws, a written waiver thereof, signed by the person entitled to notice, whether before or after the time stated therein, shall be deemed equivalent to notice. In the case of a shareholder, such waiver of notice may be signed by the shareholder's attorney or proxy duly appointed in writing. ARTICLE ELEVEN EMERGENCY POWERS 11.1 By-Laws. The Board of Directors may adopt emergency by-laws, subject to repeal or change by action of the shareholders, which shall, notwithstanding any provision of law, the certificate of incorporation or these by-laws, be operative during any emergency in the conduct of the business of the corporation resulting from an attack on the United States or on a locality in which the corporation conducts its business or customarily holds meetings of its Board of Directors or its shareholders, or during any nuclear or atomic disaster, or during the existence of any catastrophe, or other similar emergency condition, as a result of which a quorum of the Board of Directors or a standing committee thereof cannot readily be convened for action. The emergency by-laws may make any provision that may be practical and necessary for the circumstances of the emergency. 11.2 Lines of Succession. The Board of Directors, either before or during any such emergency, may provide, and from time to time modify, lines of succession in the event that during such an emergency any or all officers or agents of the corporation shall for any reason be rendered incapable of discharging their duties. 11.3 Head Office.

To the extent required to constitute a quorum at any meeting of the Board of Directors during any such emergency, the officers of the corporation who are present shall, unless otherwise provided in emergency by-laws, be deemed, in order of rank and within the same rank in order of seniority, Directors for such meeting, provided, that the emergency by-laws may declare that the Director or Directors in attendance at a meeting shall constitute a quorum. 11.7 Liability of Officers, Directors and Agents. No officer, Director, agent or employee acting in accordance with any emergency by-laws shall be liable except for willful misconduct.

No such designation as capital shall be necessary if shares are being distributed by the corporation pursuant to a split-up or division of its stock rather than as payment of a dividend declared payable in stock of the corporation.

The shareholders may provide by resolution that any by-law provision repealed, amended, adopted, or altered by them may not be repealed, amended, adopted, or altered by the Board of Directors. Action by the shareholders with respect to by-laws shall be taken by an affirmative vote of a majority of all shares entitled to elect Directors, and action by the Board of Directors with respect to by-laws shall be taken by an affirmative vote of a majority of all Directors then holding office.
