§ 7     Record Dates.

(a) In order that the corporation may determine the stockholders entitled to notice of or to vote at any meeting of stockholders or any adjournment thereof, the board of directors may fix a record date, which record date shall not precede the date on which the resolution fixing the record date is adopted by the board of directors, and which record date shall not be more than 60 nor less than 10 days before the date of such meeting (or 20 days if a merger or consolidation is to be acted upon at such meeting).

A determination of stockholders of record entitled to notice of or to vote at a meeting of stockholders shall apply to any adjournment of the meeting; provided, however, that the board of directors may fix a new record date for the adjourned meeting.

(b) In order that the corporation may determine the stockholders entitled to consent to corporate action in writing without a meeting, the board of directors may fix a record date, which record date shall not precede the date on which the resolution fixing the record date is adopted by the board of directors, and which date shall not be more than 10 days after the date upon which the resolution fixing the record date is adopted by the board of directors. If no record date has been fixed by the board of directors, the record date for determining stockholders entitled to consent to corporate action in writing without a meeting, when no prior action by the board of directors is required by the certificate of incorporation of the corporation or by statute,

If no record date has been fixed by the board of directors and prior action by the board of directors is required by the certificate of incorporation or by statute, the record date for determining stockholders entitled to consent to corporate action in writing without a meeting shall be at the close of business on the day on which the board of directors adopts the resolution taking such prior action.

(c) In order that the corporation may determine the stockholders entitled to receive payment of any dividend or other distribution or allotment of any rights or the stockholders entitled to exercise any rights in respect of any change, conversion or exchange of stock, or for the purpose of any other lawful action, the board of directors may fix a record date, which record date shall not precede the date upon which the resolution fixing the record date is adopted, and which record date shall not be more than 60 days prior to such action. If no record date is fixed, the record date for determining stockholders for any such purpose shall be at the close of business on the day on which the board of directors adopts the resolution relating thereto.

(d) Only those who shall be stockholders of record on the record date so fixed as aforesaid shall be entitled to such notice of, and to vote at, such meeting and any adjournment thereof, or to consent to such corporate action in writing, or to receive payment of such dividend or other distribution, or to receive such allotment of rights, or to exercise such rights, as the case may be, notwithstanding the transfer of any stock on the books of the corporation after the applicable record date.

§ 8     Lists Of Stockholders. The officer who has charge of the stock ledger of the corporation shall prepare and make, at least 10 days before each meeting of stockholders, a complete list of the stockholders entitled to vote thereat, arranged in alphabetical order, and showing the address of and the number of shares registered in the name of each stockholder. Such list shall be open to the examination of any stockholder, for any purpose germane to the meeting, during ordinary business hours, for a period of at least 10 days prior to the meeting, either at a place within the municipality where the meeting is to be held, which place shall be specified in the notice of the meeting, or, if not so specified, at the place where said meeting is to be held, and the list shall be produced and kept at the time and place of meeting during the whole time thereof, for inspection by any stockholder who may be present.

§ 9     Quorum and Vote Required For Action. Except as may otherwise be provided in the certificate of incorporation of the corporation, the holders of stock of the corporation having a majority of the total votes which all of the outstanding stock of the corporation would be entitled to cast at the meeting, when present in person or by proxy, shall constitute a quorum at any meeting of the stockholders; provided, however, that where a separate vote by a class or classes of stock is required, the holders of stock of such class or classes having a majority of the total votes which all of the outstanding stock of such class or classes would be entitled to cast at the meeting, when present in person or by proxy, shall constitute a quorum entitled to take action with respect to the vote on the matter. Unless a different number of votes is required by statute

or the certificate of incorporation of the corporation, (a) if a quorum is present with respect to the election of directors, directors shall be elected by a plurality of the votes cast by those stockholders present in person or represented by proxy at the meeting and entitled to vote on the election of directors, and (b) in all matters other than the election of directors, if a quorum is present at any meeting of the stockholders, a majority of the votes entitled to be cast by those stockholders present in person or by proxy shall be the act of the stockholders except where a separate vote by class or classes of stock is required, in which case, if a quorum of such class or classes is present, a majority of the votes entitled to be cast by those stockholders of such class or classes present in person or by proxy shall be the act of the stockholders of such class or classes. If a quorum is not present at any meeting of stockholders, then holders of stock of the corporation who are present in person or by proxy representing a majority of the votes cast may adjourn the meeting from time to time without further notice and, where a separate vote by a class or classes of stock is required on any matter, then holders of stock of such class or classes who are present in person or by proxy representing a majority of the votes of such class or classes cast may adjourn the meeting with respect to the vote on that matter from time to time without further notice. At any adjourned meeting at which a quorum is present, any business may be transacted which might have been transacted at the original meeting. Withdrawal of stockholders from any meeting shall not cause failure of a duly constituted quorum at that meeting.

§ 10     Proxies. Each stockholder entitled to vote at a meeting of the stockholders or to express consent to corporate action in writing without a meeting may authorize another person or persons to act for him by proxy, but no proxy shall be valid after three years from its date unless otherwise provided in the proxy. Such proxy shall be in writing and shall be filed with the secretary of the corporation before or at the time of the meeting or the giving of such written consent, as the case may be.

§ 11     Voting of Shares. Each stockholder of the corporation shall be entitled to such vote (in person or by proxy) for each share of stock having voting power held of record by such stockholder as shall be provided in the certificate of incorporation of the corporation or, absent provision therein fixing or denying voting rights, shall be entitled to one vote per share.

§ 12     Voting By Ballot. Any question or any election at a meeting of the stockholders may be decided by voice vote unless the presiding officer shall order that voting be by ballot or unless otherwise provided in the certificate of incorporation of the corporation or required by statute.

§ 13     Inspectors. At any meeting of the stockholders the presiding officer may, or upon the request of any stockholder shall, appoint one or more persons as inspectors for such meeting. Such inspectors shall ascertain and report the number of shares represented at the meeting, based upon their determination of the validity and effect of proxies; count all votes and report the results; and do such other acts as are proper to conduct the election and voting with impartiality and fairness to all the stockholders. Each report of an inspector shall be in writing and signed by him or a majority of them if there is more than one inspector acting at such meeting. If there is more than one inspector, the report of a majority shall be the report of the inspectors. The report of the inspector or inspectors on the number of shares represented at the meeting and the results of the voting shall be prima facie evidence thereof.

§ 14     Informal Action. Any corporate action upon which a vote of stockholders is required or permitted may be taken without a meeting, without prior notice and without a vote, if a consent in 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 in the manner required by law at its registered office within the State of Delaware or at its principal place of business or to an officer or agent of the corporation having custody of the book in which proceedings of meetings of stockholders of the corporation 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 60 days of the earliest dated consent delivered, as aforesaid, written consents signed by a sufficient number of holders to take action are delivered to the corporation in the manner required by law at its registered office within the State of Delaware or at its principal place of business or to an officer or agent of the corporation having or at its principal place of business or to an officer or agent of the corporation having custody of the book in which proceedings of meetings of stockholders of the corporation 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 so consented in writing.

§ 2     Number, Election Term of Office and Qualifications. The number of directors which shall constitute the whole board shall be that number determined by the board from time to time. The directors shall be elected at the annual meeting of the stockholders, except as provided in § 3.3, and each director elected shall hold office until his or her successor is elected and qualified or until his or her earlier death, resignation or removal in a manner permitted by statute or these by-laws. Directors need not be stockholders.

Vacancies occurring in the board of directors and newly-created directorships resulting from any increase in the authorized number of directors may be filled by a majority of the directors then in office, although less than a quorum, or by a sole remaining director, and any director so chosen shall hold office until the next annual election of directors and until his or her successor is duly elected and qualified or until his or her earlier death, resignation or removal in a manner permitted by statute or these by-laws.

§ 4     Regular Meetings. A regular meeting of the board of directors shall be held immediately following the close of, and at the same place as, each annual meeting of

stockholders. No notice of any such meeting, other than this by-law, shall be necessary in order legally to constitute the meeting, provided a quorum shall be present. In the event such meeting is not held at such time and place the meeting may be held at such time and place as shall be specified in a notice given as hereinafter provided for special meetings of the board of directors or as shall be specified in a written waiver signed by all of the directors. The board of directors may provide, by resolution, the time and place for the holding of additional regular meetings without notice other than such resolution.

§ 7     Waiver Of Notice. A written waiver of notice, signed by a director entitled to notice of a meeting of the board of directors or of a committee of such board of which the director is a member, whether before or after the time stated therein, shall be deemed equivalent to the giving of such notice to that director. Attendance of a director at a meeting of the board of directors or of a committee of such board of which the director is a member shall constitute a waiver of notice of such meeting except when the director attends the 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.

§ 8     Quorum and Vote Required For Action. At all meetings of the board of directors, a majority of the number of directors fixed by these by-laws shall constitute a quorum for the transaction of business and 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 statute, the certificate of incorporation of the corporation or these by-laws.

A director of the corporation who is present at a duly convened meeting of the board of directors at which action on any corporate matter is taken shall be conclusively presumed to have assented to the action taken unless his or her dissent shall be entered in the minutes of the meeting or unless he or she shall file his or her written dissent to such action with the person acting as the secretary of the meeting before the adjournment thereof or shall forward such dissent by registered or certified mail to the secretary of the corporation immediately after the adjournment of the meeting. Such right to dissent shall not apply to a director who voted in favor of such action.

§ 11     Informal Action. Unless otherwise restricted by statute, the certificate of incorporation of the corporation or these by-laws, 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 the directors or by all the members of such committee, as the case may be, and such written consent is filed with the minutes of proceedings of the board of directors or of such committee.

§ 12     Compensation. The directors may be paid their expenses, if any, of attendance at each meeting of the board of directors and at each meeting of a committee of the board of directors of which they are members.

CERTIFICATES OF STOCK AND THEIR TRANSFER

§ 1     Form And Execution Of Certificates. Every holder of stock in the corporation shall be entitled to have a certificate signed by, or in the name of, the corporation by the president or a vice president and by the secretary or an assistant secretary of the corporation, certifying the number of shares owned.

When authorizing such issue of a new certificate, 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 his legal representative, to advertise the same in such manner as it shall require and may require such owner 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 alleged to have been lost, stolen or destroyed. The board of directors may delegate its authority to direct the issuance of replacement stock certificates to the transfer agent or agents of the corporation upon such conditions precedent as may be prescribed by the board.

§ 3     Transfers of Stock.
