STOCKHOLDERS

Section 1.01. Annual Meetings . The annual meeting of the stockholders of the Corporation for the election of directors and for the transaction of such other business as properly may come before such meeting shall be held at such place, either within or without the State of

Delaware, and at such date and hour, as may be fixed from time to time by resolution of the Board of Directors and set forth in the notice or waiver of notice of the meeting.

Section 1.02. Special Meetings . Special meetings of the stockholders may be called at any time by the Chief Executive Officer or the Secretary or by the Board of Directors. A special meeting shall be called by the Chief Executive Officer or by the Secretary immediately upon receipt of a written request therefor by stockholders holding in the aggregate not less than one-third in number of the outstanding shares of the Corporation at the time entitled to vote at any meeting of the stockholders. Such special meetings of the stockholders shall be held at such places, within or without the State of Delaware, as shall be specified in the respective notices or waivers of notice thereof.

Section 1.03. Notice of Meetings; Waiver . The Secretary or any Assistant Secretary shall cause written notice of the place, date and hour of each meeting of the stockholders, and, in the case of a special meeting, the purpose or purposes for which such meeting is called, to be given personally or by mail, not less than ten nor more than sixty days prior to the meeting, to each stockholder of record entitled to vote at such meeting. If such notice is mailed, it shall be deemed to have been given to a stockholder when deposited in the United States mail, postage prepaid, directed to the stockholder at his address as it appears on the record of stockholders of the Corporation, or, if he or she shall have filed with the Secretary of the Corporation a written request that notices to him or her be mailed to some other address, then directed to him or her at such other address. Such further notice shall be given as may be required by law.

No notice of any meeting of stockholders need be given to any stockholder who submits a signed waiver of notice, whether before or after the meeting. Neither the business to be transacted at, nor the purpose of, any regular or special meeting of the stockholders need be specified in a written waiver of notice. The attendance of any stockholder at a meeting of stockholders shall constitute a waiver of notice of such meeting, except when the stockholder attends a meeting for the express purpose of objecting, at the beginning of the meeting, to the transaction of any business on the ground that the meeting is not lawfully called or convened.

Section 1.04. Quorum . Except as otherwise required by law or by the Certificate of Incorporation, the presence in person or by proxy of the holders of record of a majority of the shares entitled to vote at a meeting of stockholders shall constitute a quorum for the transaction of business at such meeting.

Section 1.05. Voting . If, pursuant to Section 5.05 of these By-Laws, a record date has been fixed, every holder of record of shares entitled to vote at a meeting of stockholders shall be entitled to one vote for each share outstanding in his or her name on the books of the Corporation at the close of business on such record date. If no record date has been fixed, then every holder of record of shares entitled to vote at a meeting of stockholders shall be entitled to one vote for each share of stock standing in his or her name on the books of the Corporation at the close of business on the day next preceding the day on which notice of the meeting is given, or, if notice is waived, at the close of business on the day next preceding the day on which the meeting is held. Except as otherwise required by law or by the Certificate of Incorporation or by these By-Laws, the vote of a majority of the shares represented in person or by proxy at any meeting at which a quorum is present shall be sufficient for the transaction of any business at such meeting.

Section 1.06. Voting by Ballot . No vote of the stockholders need be taken by written ballot unless demanded by the holders of at least fifteen percent (15%) of the shares represented in person or by proxy at any meeting at which a quorum is present or as otherwise required by law. Any vote which need not be taken by ballot may be conducted in any manner approved by the meeting.

Section 1.07. Adjournment . If a quorum is not present at any meeting of the stockholders, the holders of a majority of the shares present in person or by proxy shall have the power to adjourn any such meeting from time to time until a quorum is present. Notice of any adjourned meeting of the stockholders of the Corporation need not be given if the place, date and hour thereof are announced at the meeting at which the adjournment is taken, provided, however, that if the adjournment is for more than thirty days, or if after the adjournment a new record date for the adjourned meeting is fixed pursuant to Section 5.05 of these By-Laws, a notice of the adjourned meeting, conforming to the requirements of Section 1.03 of these By-Laws, shall be given to each stockholder of record entitled to vote at such meeting. At any adjourned meeting at which a quorum is present, any business may be transacted that might have been transacted on the original date of the meeting.

Section 1.08. Proxies . Any stockholder entitled to vote at any meeting of the stockholders or to express consent to or dissent from corporate action in writing without a meeting may authorize another person or persons to vote at any such meeting and express such consent or dissent for him or her by proxy. Every proxy shall be revocable at the pleasure of the stockholder executing it, except in those cases where applicable law provides that a proxy shall be irrevocable. A stockholder may revoke any proxy which is not irrevocable by attending the meeting and voting in person or by filing an instrument in writing revoking the proxy or by filing another duly executed proxy bearing a later date with the Secretary.

Section 1.09. Organization; Procedure . At every meeting of stockholders the presiding officer shall be the Chairman or, in the event of his or her absence or should the Chairman in his

2

or her discretion determine not to preside, in the following order of availability, the Chief Executive Officer, the President, or a Vice President, and in the case more than one Vice President shall be present, that Vice President designated by the Board of Directors (or in the absence of any such designation, the most senior Vice President, based on title). In case none of the foregoing officers designated to be the presiding officer shall be present, a presiding officer shall be chosen by the vote of a majority of the shares represented in person or by proxy and entitled to vote at the meeting.

The order of business and all other matters of procedure at every meeting of stockholders may be determined by such presiding officer.

Section 1.10. Inspectors of Elections . Preceding any meeting of the stockholders, the Board of Directors shall appoint one or more persons to act as Inspectors of Elections, and may designate one or more alternate inspectors. In the event no inspector or alternate is able to act, the person presiding at the meeting shall appoint one or more inspectors to act at the meeting. Each inspector, before entering upon the discharge of the duties of an inspector, shall take and sign an oath faithfully to execute the duties of inspector with strict impartiality and according to the best of his or her ability. The inspector shall:

(a) ascertain the number of shares outstanding and the voting power of each;

(b) determine the shares represented at a meeting and the validity of proxies and ballots;

(d) determine and retain for a reasonable period a record of the disposition of any challenges made to any determination by the inspectors; and

(e) certify his or her determination of the number of shares represented at the meeting, and his or her count of all votes and ballots.

The inspector may appoint or retain other persons or entities to assist in the performance of the duties of inspector.

Section 1.11. Opening and Closing of Polls . The date and time for the opening and the closing of the polls for each matter to be voted upon at a stockholder meeting shall be announced at the meeting. The inspector of the election shall be prohibited from accepting any ballots, proxies or votes or any revocations thereof or changes thereto after the closing of the polls, unless the Court of Chancery upon application by a stockholder shall determine otherwise.

Section 1.12. Consent of Stockholders in Lieu of Meeting . To the fullest extent permitted by law, whenever the vote of stockholders at a meeting thereof is required or permitted to be taken for or in connection with any corporate action, such action may be taken without a meeting, without prior notice and without a vote of stockholders, if a consent or consents in

3

writing, setting forth the action so taken, shall be signed by the holders of outstanding stock having not less than the minimum number of votes that would be necessary to authorize or take such action at a meeting at which all shares entitled to vote thereon were present and voted and shall be delivered to the Corporation by delivery to its registered office in the State of Delaware, its principal place of business, or an officer or agent of the Corporation having custody of the book in which proceedings of meetings of stockholders are recorded.

Every written consent shall bear the date of signature of each stockholder who signs the consent and no written consent shall be effective to take the corporate action referred to therein unless, within sixty days of the earliest dated consent delivered in the manner required by law to the Corporation, written consents signed by a sufficient number of holders to take action are delivered to the Corporation by delivery to its registered office in the State of Delaware, its principal place of business, or an officer or agent of the Corporation having custody of the book in which proceedings of meetings of stockholders are recorded. Prompt notice of the taking of the corporate action without a meeting by less than unanimous written consent shall be given to those 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 as provided in this Section 1.12.
