The holders of a majority of the stock issued and outstanding and entitled to vote thereat, present in person or represented by proxy, shall constitute a quorum at any meeting of stockholders for the transaction of business except at each election of directors and as otherwise provided by statute or by the Certificate of Incorporation.

If any stockholder entitled to vote at any meeting shall be present at such meeting and such stockholder shall abstain, whether in person or by proxy, from casting the vote or votes which he or it is entitled to cast at such meeting, such abstention shall not affect the determination of the presence of a quorum at such meeting. For all purposes of these by-laws, an abstention from voting on any matter properly submitted to stockholders at a meeting shall not be considered a vote cast for or against such matter.

(b) Each stockholder having the right to vote shall be entitled to vote in person or by proxy appointed by an instrument in writing subscribed by the stockholder, bearing a date not more than three years prior to voting, unless such instrument provides for a longer period, and is filed with the Secretary of the corporation before, or at the time of, the meeting. If such instrument shall designate two or more persons to act as proxies, unless such instrument shall provide to the contrary, a majority of such persons present at any meeting at which their powers thereunder are to be exercised shall have and may exercise all of the powers of voting or giving consents thereby conferred, or if only one be present, then such powers may be exercised by that one.

2

(c) An instrument in writing subscribed by a stockholder and appointing a proxy may confer upon such proxy discretionary power to vote on any matter that may come before an annual meeting of the stockholders of the corporation unless, with respect to a particular matter, (i) the corporation receives, by certified mail, return receipt requested, addressed to the corporation’s Secretary, notice not later than the 15th day of February next preceding the annual meeting that the matter will be presented at the annual meeting and (ii) the corporation fails to include in its proxy statement for the annual meeting advice on the nature of the matter and how the corporation intends to exercise its discretion to vote on the matter.

(d) When a quorum is present at any meeting of stockholders, a majority of the shares voted in person or by proxy shall decide any question brought before such meeting, unless the question is one upon which, by express provision of an applicable statute, of the Certificate of Incorporation or of these by-laws, a different vote is required, in which case such express provision shall govern and control the decision of such question.

(e) When a quorum is present at any meeting of stockholders at which the Board of Directors is to be elected, the stockholders shall elect such directors by a plurality of the shares voted in person or by proxy. All votes for election of directors that are cast in person shall be cast by written ballot.

SECTION 2.8. Consent of Stockholders. Whenever the vote of stockholders at a meeting thereof is required or permitted to be taken for or in connection with any corporate action by statute, the meeting and vote of stockholders may be dispensed with if all the stockholders who would have been entitled to vote upon the action if such meeting were held shall consent in writing to such corporate action being taken; or if the Certificate of Incorporation authorizes the action to be taken with the written consent of the holders of less than all the stock who would have been entitled to vote upon the action if a meeting were held, then on the written consent of the stockholders or any class of stockholders having not less than such percentage of the number of votes as may be authorized in the Certificate of Incorporation; provided that in no case shall the written consent be by the holders of stock having less than the minimum percentage of the vote required by statute for the proposed corporate action, and provided that prompt notice must be given to stockholders or any class of stockholders who would have been entitled to vote on the taking of corporate action by stockholders without a meeting and by less than unanimous consent. Notwithstanding the foregoing, or Section 2.5 or Section 5.1, whenever the vote of holders of Class B Common stock is taken, notice of a meeting at which such vote is to be taken may be communicated verbally, electronically, or in writing to all holders of Class B Common stock; provided, however, that the holders of a majority of Class B Common stock can waive any timing or other requirements of any notice.

SECTION 2.9. Voting of Stock of Certain Holders. Shares standing in the name of another corporation, domestic or foreign, may be voted by such officer, agent or proxy as the by-laws of such corporation may prescribe, or in the absence of such provision, as the Board of Directors of such corporation may determine. Shares standing in the name of a deceased person may be voted by the executor or administrator of such deceased person, either in person or by proxy. Shares standing in the name of a guardian, conservator or trustee may be voted by such fiduciary, either in person or by proxy, but no such fiduciary shall be entitled to vote shares held in such fiduciary capacity without a transfer of such shares into the name of

3

such fiduciary. Shares standing in the name of a receiver may be voted by such receiver. A stockholder whose shares are pledged shall be entitled to vote such shares, unless in the transfer by the pledger on the books of the corporation, he has expressly empowered the pledgee to vote thereon, in which case only the pledgee, or his proxy, may represent the stock and vote thereon.

SECTION 2.10. Treasury Stock. The corporation shall not vote, directly or indirectly, shares of its own stock owned by it; and such shares shall not be counted in determining the total number of outstanding shares.

SECTION 2.11. Fixing Record Date. The Board of Directors may fix in advance a date, not exceeding 60 days preceding the date of any meeting of stockholders, or the date for payment of any dividend or distribution, or the date for the allotment of rights, or the date when any change, or conversion or exchange of capital stock shall go into effect, or a date in connection with obtaining a consent, as a record date for the determination of the stockholders entitled to notice of, and to vote at, any such meeting and any adjournment thereof, or entitled to receive payment of any such dividend or distribution, or to receive any such allotment of rights, or to exercise the rights in respect of any such change, conversion or exchange of capital stock, or to give such consent, and in such case such stockholders and only such stockholders as shall be stockholders of record on the date so fixed shall be entitled to such notice of, and to vote at, any such meeting and any adjournment thereof, or to receive payment of such dividend or distribution, or to receive such allotment of rights, or to exercise such rights, or to give such consent, as the case may be, notwithstanding any transfer of any stock on the books of the corporation after any such record date fixed as aforesaid.

SECTION 3.1. Powers. The business and affairs of the corporation shall be managed by its Board of Directors, which may exercise all such powers of the corporation and do all such lawful acts and things as are not by statute or by the Certificate of Incorporation or by these by-laws directed or required to be exercised or done by the stockholders.

SECTION 3.2. Number, Election and Term. The number of directors which shall constitute the whole Board shall be NINE. Unless such number is fixed by express provision of the statutes or the Certificate of Incorporation, in which case such express provision shall govern and control, the number of directors shall from time to time be fixed and determined by the directors and shall be set forth in the notice of any meeting of stockholders held for the purpose of electing directors.

SECTION 3.3. Vacancies, Additional Directors and Removal from Office.

4

the directors then in office elected by the holders of Common stock, though less than a quorum, or a sole remaining such director, may choose a successor or fill the newly created directorship; and a director so chosen shall hold office until the next annual election and until his successor shall be duly elected and shall qualify, unless sooner displaced. If any vacancy occurs in the members of the Board of Directors elected by the holders of Class B Common stock caused by death, resignation, retirement, disqualification or removal from office of any such director, or otherwise, or if any new directorship to be elected by the holders of Class B Common stock is created by an increase in the authorized number of directors, a majority of the directors then in office elected by the holders of Class B Common stock, though less than a quorum, or a sole remaining such director, may choose a successor or fill the newly created directorship; and a director so chosen shall hold office until the next annual election and until his successor shall be duly elected and shall qualify, unless sooner displaced.

Such notice shall be deemed given effectively if given in person or by telephone, mail, facsimile, electronic mail or by other means of electronic transmission delivered in accordance with Section 5.1 hereto. Any director may waive notice of any meeting. The attendance of a director at any meeting shall constitute a waiver of notice of such meeting except for the purpose of objecting 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 special meeting of the Board of Directors need be specified in the notice or waiver of notice of such meeting, except that notice shall be given of any proposed amendment to the by-laws if it is to be adopted or with respect to any other matter where notice is required by statute.

SECTION 3.7. Quorum and Vote Required. Six of the nine members of the Board of Directors shall constitute a quorum for the transaction of business at any meeting of the Board of Directors, and the act of six of the directors shall be the act of the Board of Directors, except as may be otherwise specifically provided by statute, by the Certificate of Incorporation

No provision of these by-laws shall be construed to preclude any director from serving the corporation in any other capacity and receiving compensation therefor.

The Advisory Members of the Board of Directors may be elected at any regular or special meeting of the Board of Directors. The Advisory Members of the Board of Directors shall receive the same fee for attending a meeting that a Director receives and shall be paid their travel expenses, if any, incurred in attending meetings of the Board of Directors.

They shall exhibit the holder’s name and number of shares and shall be signed by the Chief Executive Officer, the President or a Vice President and by the Secretary or an Assistant Secretary. If any certificate is countersigned (1) by a transfer agent other than the corporation or any employee of the corporation, or (2) by a registrar other than the corporation or any employee of the corporation, any other signature on the certificate may be a facsimile. If the corporation shall be authorized to issue more than one class of stock or more than one series of any class, the designations, preferences and relative participating, optional or other special rights of each class of stock or series thereof and the qualifications, limitations or restrictions of such preferences and rights shall be set forth in full or summarized on the face or back of the certificate which the corporation shall issue to represent such class of stock; provided that, except as otherwise provided by statute, in lieu of the foregoing requirements there may be set forth on the face or back of the certificate which the corporation shall issue to represent such class or series of stock, a statement that the corporation will furnish to each stockholder who so requests the designations, preferences and relative, participating, optional or other special rights of each class of stock or series thereof and qualifications, limitations or restrictions of such preferences and rights. All certificates surrendered to the corporation for transfer shall be cancelled and no new certificate shall be issued until the former certificate for a like number of shares shall have been surrendered and cancelled, except that in the case of a lost, stolen, destroyed or mutilated certificate a new one may be issued therefor upon such terms and with such indemnity, if any, to the corporation as the Board of Directors may prescribe. Certificates shall not be issued representing fractional shares of stock.

SECTION 8.2. Lost Certificates. The Board of Directors may direct a new certificate or certificates to be issued in place of any certificate or certificates theretofore issued by the corporation alleged to have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming the certificate of stock to be lost, stolen or destroyed. When authorizing such issue of a new certificate or certificates, the Board of Directors may, in its discretion and as a condition precedent to the issuance thereof, require the owner of such lost, stolen or destroyed certificate or certificates, or his legal representative, to advertise the same in

12

such manner as it shall require or to give the corporation a bond in such sum as it may direct as indemnity against any claim that may be made against the corporation with respect to the certificate or certificates alleged to have been lost, stolen or destroyed, or both.

SECTION 8.3. Transfers. Upon surrender to the corporation or the transfer agent of the corporation of a certificate for shares duly endorsed or accompanied by proper evidence of succession, assignment or authority to transfer, it shall be the duty of the corporation to issue a new certificate to the person entitled thereto, cancel the old certificate and record the transaction upon its books. Transfers of shares shall be made only on the books of the corporation by the registered holder thereof, or by his attorney thereunto authorized by power of attorney and filed with the Secretary of the corporation or the Transfer Agent.

SECTION 8.4. Registered Stockholders. The corporation shall be entitled to treat the holder of record of any share or shares of stock as the holder in fact thereof and, accordingly, shall not be bound to recognize any equitable or other claim to or interest in such share or shares on the part of any other person, whether or not it shall have express or other notice thereof, except as otherwise provided by the laws of the State of Delaware.

ARTICLE X

INDEMNIFICATION

SECTION 10.1. Right to Indemnification. Each person who was or is made a party or is threatened to be made a party to or is otherwise involved in any action, suit or proceeding, whether civil, criminal, administrative or investigative (hereinafter a “proceeding”), by reason of the fact that he or she is or was a director, Advisory Member of the Board of Directors or officer of the corporation or is or was serving at the request of the corporation as a director, Advisory Member of the Board of Directors, officer, or trustee of another corporation or of a partnership, joint venture, trust or other enterprise, including service with respect to an employee benefit plan (hereinafter an “indemnitee”), whether the basis of such proceeding is alleged action in an official capacity as a director, Advisory Member of the Board of Directors,

13

officer or trustee, or in any other capacity while serving as a director, Advisory Member of the Board of Directors, officer or trustee, shall be indemnified and held harmless by the corporation to the fullest extent authorized by the Delaware General Corporation Law, as the same exists or may hereafter be amended (but, in the case of any such amendment, only to the extent that such amendment permits the corporation to provide broader indemnification rights than such law permitted the corporation to provide prior to such amendment), against all expense, liability and loss (including attorneys’ fees, judgments, fines, ERISA excise taxes or penalties and amounts paid in settlement) reasonably incurred or suffered by such indemnitee in connection therewith; provided, however, that, except as provided in Section 10.3 with respect to proceedings to enforce rights to indemnification, the corporation shall indemnify any such indemnitee in connection with a proceeding (or part thereof) initiated by such indemnitee only if such proceeding (or part thereof) was authorized by the Board of Directors of the corporation.

SECTION 10.2. Right to Advancement of Expenses. In addition to the right to indemnification conferred in Section 10.1, an indemnitee shall also have the right to be paid by the corporation the expenses (including attorney’s fees) incurred in defending any such proceeding in advance of its final disposition (hereinafter an “advancement of expenses”); provided, however, that, if the Delaware General Corporation Law requires, an advancement of expenses incurred by an indemnitee in his or her capacity as a director or officer (and not in any other capacity in which service was or is rendered by such indemnitee, including, without limitation, service to an employee benefit plan) shall be made only upon delivery to the corporation of an undertaking (hereinafter an “undertaking”), by or on behalf of such indemnitee, to repay all amounts so advanced if it shall ultimately be determined by final judicial decision from which there is no further right to appeal (hereinafter a “final adjudication”) that such indemnitee is not entitled to be indemnified for such expenses under this Section 10.2 or otherwise.

SECTION 10.3. Right of Indemnitee to Bring Suit. If a claim under Section 10.1 or 10.2 is not paid in full by the corporation within sixty (60) days after a written claim has been received by the corporation, except in the case of a claim for an advancement of expenses, in which case the applicable period shall be twenty (20) days, the indemnitee may at any time thereafter bring suit against the corporation to recover the unpaid amount of the claim. If successful in whole or in part in any such suit, or in a suit brought by the corporation to recover an advancement of expenses pursuant to the terms of an undertaking, the indemnitee shall be entitled to be paid also the expense of prosecuting or defending such suit. In (i) any suit brought by the indemnitee to enforce a right to indemnification hereunder (but not in a suit brought by the indemnitee to enforce a right to an advancement of expenses) it shall be a defense that, and (ii) in any suit brought by the corporation to recover an advancement of expenses pursuant to the terms of an undertaking, the corporation shall be entitled to recover such expenses upon a final adjudication that, the indemnitee has not met any applicable standard for indemnification set forth in the Delaware General Corporation Law. Neither the failure of the corporation (including its directors who are not parties to such action, a committee of such directors, independent legal counsel, or its stockholders) to have made a determination prior to the commencement of such suit that indemnification of the indemnitee is proper in the circumstances because the indemnitee has met the applicable standard of conduct set forth in the Delaware General Corporation Law, nor an actual determination by the corporation (including its directors who are not parties to such action,

14

a committee of such directors, independent legal counsel, or it stockholders) that the indemnitee has not met such applicable standard of conduct, shall create a presumption that the indemnitee has not met the applicable standard of conduct or, in the case of such a suit brought by the indemnitee, be a defense to such suit. In any suit brought by the indemnitee to enforce a right to indemnification or to an advancement of expenses hereunder, or brought by the corporation to recover an advancement of expenses pursuant to the terms of an undertaking, the burden of proving that the indemnitee is not entitled to be indemnified, or to such advancement of expenses, under this Article X or otherwise shall be on the corporation.

SECTION 10.4. Non-Exclusivity of Rights. The rights to indemnification and to the advancement of expenses conferred in this Article X shall not be exclusive of any other right which any person may have or hereafter acquire under any statute, the corporation’s Certificate of Incorporation, by-laws, agreement, vote of stockholders or disinterested directors or otherwise.

SECTION 10.5. Insurance. The corporation may maintain insurance, at its expense, to protect itself and any director, Advisory Member of the Board of Directors, officer, employee or agent of the corporation or another corporation, partnership, joint venture, trust or other enterprise against any expense, liability or loss, whether or not the corporation would have the power to indemnify such person against such expense, liability or loss under the Delaware General Corporation Law.

SECTION 10.6. Indemnification of Employees and Agents of the corporation. The corporation may, to the extent authorized from time to time by the Board of Directors, grant rights to indemnification and to the advancement of expenses to any employee or agent of the corporation to the fullest extent of the provisions of this Article X with respect to the indemnification and advancement of expenses of directors and officers of the corporation.

SECTION 10.7. Nature of Rights. The rights conferred upon indemnities in this Article X shall be contract rights and such rights shall continue as an indemnitee who has ceased to be a director, Advisory Member of the Board of Directors, officer or trustee and shall inure to the benefit of the indemnitee’s heirs, executors and administrators. Any amendment, alteration or repeal of this Article X that adversely affects any right of an indemnitee or its successors shall be prospective only and shall not limit or eliminate any such right with respect to any proceeding involving any occurrence or alleged occurrence of any action or omission to act that took place prior to such amendment, alteration or repeal.
