A telegram, telex, cablegram or other electronic transmission by a shareholder consenting to an action to be taken is considered to be written, signed, and dated for the purposes of this Section 2.08 if the transmission sets forth or is delivered with information from which the corporation can determine that the transmission was transmitted by the shareholder and the date on which the shareholder transmitted the transmission. The date of transmission is the date on which the consent was signed.

Consent given by telegram, telex, cablegram, or other electronic transmission may be delivered to the principal place of business of the corporation or to an officer or agent of the corporation having custody of the book in which proceedings of shareholder meetings are recorded to the extent and in the manner provided by resolution of the board of directors of the corporation.

Notice of each special meeting of the board of directors shall be given to each director at least two days before the date of the meeting.

Section 3.10. Waiver and Requirements of Notice.

Except as may be otherwise provided by law or by the Certificate of Formation or by these bylaws, neither the business to be transacted at, nor the purpose of, any regular or special meeting of the board of directors need be specified in the notice or waiver of notice of such meeting.

4

Section 3.11. Quorum; Vote Required. At all meetings of the board of directors a majority of the directors 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, unless otherwise specifically provided by law, the Certificate of Formation or these bylaws.

Any such committee shall have and may exercise such powers, as the board may determine and specify in the respective resolutions appointing them. A majority of all the members of any such committee may determine its action and fix the time and place of its meetings, unless the board of directors shall otherwise provide. The board of directors shall have power at any time to change the number, subject as aforesaid, and members of any such committee, to fill vacancies and to discharge any such committee.

Section 3.13. Action Without Meeting. Any action required or permitted to be taken at a meeting of the board of directors or any committee may be taken without a meeting if a consent in writing, setting forth the action so taken, is signed by all of the members of the board of directors or committee, as the case may be. A telegram, telex, cablegram, or other electronic transmission by a director consenting to an action to be taken and transmitted by a director is considered written, signed, and dated for the purposes of this Section 3.13 if the transmission sets forth or is delivered with information from which the corporation can determine that the transmission was transmitted by the director and the date on which the director transmitted the transmission.

Section 3.14. Compensation. By resolution of the board of directors, the directors may be paid their expenses, if any, of attendance at each meeting of the board of directors, or a meeting of a committee thereof, and may be paid a fixed sum for attendance at each meeting of the board of directors, or a meeting of a committee thereof, or a stated salary as director.

NOTICES

Section 4.01. Form of Notice; Delivery. Any notice to directors or shareholders shall be in writing and shall be delivered personally, by electronic transmission (to the extent permitted by Section 4.02), or by mail to the directors or shareholders at their respective addresses appearing on the books of the corporation. Notice by mail shall be deemed to be given at the time when the same shall be deposited in the United States mail, postage prepaid.

Section 4.02. Notice by Electronic Transmission. On consent of a director or shareholder, notice from the corporation may be given to the director or shareholder by electronic transmission. The director or shareholder may specify the form of electronic transmission to be used to communicate notice. The director or shareholder may revoke this consent by written notice to the corporation. The director’s or shareholder’s consent is deemed to be revoked if the corporation is unable to deliver by electronic transmission two consecutive notices and the secretary of the corporation or other person responsible for delivering the notice on behalf of the corporation knows that the delivery of these two electronic transmissions was unsuccessful. The inadvertent failure to treat the unsuccessful transmissions as a revocation of the director’s or shareholder’s consent does not invalidate a meeting or other action. Notice under this Section 4.02 is deemed given when the notice is (i) transmitted to a facsimile number provided by the director or shareholder for the purpose of receiving notice; (ii) transmitted to an electronic mail address provided by the director or shareholder for the purpose of receiving notice; (iii) posted on an electronic network and a message is sent to the director or shareholder at the address provided by the director or shareholder for the purpose of alerting the director or shareholder of a posting; or (iv) communicated to the director or shareholder by any other form of electronic transmission consented to by the director or shareholder.

Section 4.03. Waiver. Whenever any notice is required to be given under the provisions of the statutes or of the Certificate of Formation or of these bylaws, a waiver thereof in writing signed by the person or persons entitled to such notice, or a waiver by electronic transmission, whether before or after the time stated therein, shall be deemed equivalent to the giving of such notice. The business to be transacted at a regular or special meeting of the shareholders, directors, or members of a committee of directors or the purpose of a meeting is not required to be specified in a written waiver of notice or a waiver by electronic transmission.

Section 6.03. Lost Certificates. The board of directors may direct a new certificate to be issued in place of any certificate theretofore issued by the corporation alleged to have been lost or destroyed. When authorizing such issue of a new certificate, the board of directors, in its discretion and as a condition precedent to the issuance thereof, may prescribe such terms and conditions as it deems expedient and may require such indemnities as it deems adequate to protect the corporation from any claim that may be made against it with respect to any such certificate alleged to have been lost or destroyed.

Upon surrender to the corporation or the transfer agent of the corporation of a certificate representing shares duly endorsed or accompanied by proper evidence of succession, assignment or authority to transfer, a new certificate shall be issued to the person entitled thereto and the old certificate canceled and the transaction recorded upon the transfer records of the corporation.

Section 6.05. Closing of Transfer Records. For the purpose of determining shareholders (i) entitled to notice of or to vote at any meeting of shareholders, or, after an adjournment thereof, at any reconvened meeting, (ii) entitled to receive a distribution (other than a distribution involving a purchase or redemption by the corporation of any of its own shares) or a share dividend or (iii) for any other proper purpose (other than determining shareholders entitled to consent to action by shareholders proposed to be taken without a meeting of shareholders), the board of directors may provide that the share transfer records shall be closed for a stated period but not to exceed, in any case, sixty days. If the share transfer records shall be closed for the purpose of determining shareholders entitled to notice of or to vote at a meeting of shareholders, such records shall be closed for at least ten days immediately preceding such meeting. In lieu of closing the share transfer records, the board of directors may fix in advance a date as the record date for any such determination of shareholders, such date in any case to be not more than sixty days and, in the 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. If the share transfer records are not closed and no record date is fixed for the determination of shareholders entitled to notice of or to vote at a meeting of shareholders, or shareholders entitled to receive a distribution (other than a distribution involving a purchase or redemption by the corporation of any of its own shares) or a share dividend, the date on which notice of the meeting is mailed or the date on which the resolution of the board of directors declaring such distribution or share dividend is adopted, as the case may be, shall be the record date for such determination of shareholders. When a determination of shareholders entitled to vote at any meeting of shareholders has been made as provided in this Section 6.05, such determination shall be applied after an adjournment thereof to any reconvened meeting except where the determination has been made through the closing of the share transfer records and the stated period of closing has expired.

Section 6.06. Fixing Record Dates for Consents to Action. Unless a record date shall have previously been fixed or determined, whenever action by shareholders is proposed to be taken by consent in writing or by electronic transmission without a meeting of shareholders, the board of directors may fix a record date for the purpose of determining shareholders entitled to consent to that action which record date shall not precede, and shall not be more than ten 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 and prior action of the board of directors is not required by law, the record date for determining shareholders entitled to consent to action in writing or by electronic transmission without a meeting shall be the first date on which a signed written consent or electronic transmission setting forth the action taken or proposed to be taken is delivered to or received by the corporation in the manner required by Section 2.08 of these bylaws. If no record date shall have been fixed by the board of directors and prior action of the board of directors is required by law, the record date for determining shareholders entitled to consent to action in writing or by electronic transmission without a meeting shall be at the close of business on the date on which the board of directors adopts a resolution taking such prior action.

Section 6.07. Registered Shareholders. Except as otherwise required by law, the corporation shall be entitled to regard the person in whose name any shares are registered in the share transfer records at any particular time as the owner of those shares at that time for purposes of voting those shares, receiving distributions, share dividends or notices in respect thereof, transferring those shares, exercising rights of dissent with respect to those shares, exercising or waiving any preemptive right with respect to those shares, entering into agreements with respect to those shares or giving proxies with respect to those shares. Except as otherwise required by law, neither the corporation nor any of its officers, directors, employees or agents shall be liable for regarding that person as the owner of those shares at that time for those purposes, regardless of whether that person does not possess a certificate for those shares.

Section 6.08. List of Shareholders. The officer or agent having charge of the transfer books for shares shall make, at least ten days before each meeting of shareholders, a complete list of the shareholders entitled to vote at such meeting, arranged in alphabetical order, with the address of each and the number of shares held by each, which list, for a period of ten days prior to such meeting, shall be kept on file at the registered office or principal place of business of the corporation and shall be subject to inspection by any shareholder at any time during usual business hours. Alternatively, the list of the shareholders may be kept on a reasonably accessible electronic network, if the information required to gain access to the list is provided with the notice of the meeting. The corporation does not need to include any electronic contact information of any shareholder on the list. If the corporation elects to make the list available on an electronic network, the corporation shall take reasonable steps to ensure that the information is available only to shareholders of the corporation. Such list shall also be produced and kept open at the time and place of the meeting and shall be subject to the inspection of any shareholder during the whole time of the meeting. If the meeting is held by means of remote communication, the list must be open to the examination of any shareholder for the duration of the meeting on a reasonably accessible electronic network, and the information required to access the list must be provided to shareholders with the notice of the meeting. The original share transfer records, or a duplicate thereof, shall be prima facie evidence as to who are the shareholders entitled to examine such list or transfer records or to vote at any meeting of the shareholders.
