Whenever any notice is required to be given to any stockholder, a written waiver of notice signed by the person or persons entitled to such notice, whether before or after the time stated in the waiver, shall be deemed equivalent to the giving of such notice; and attendance of a stockholder at any meeting shall constitute a waiver of notice of the meeting unless such attendance is for the sole purpose of objecting to the transaction of any business on the ground that the meeting was not lawfully called or convened.

For the purpose of determining stockholders entitled to notice of or to vote at any meeting of stockholders or any adjournment thereof, or stockholders entitled to receive payment of any dividend, or in order to make a determination of stockholders for any other proper purpose, the Board of Directors of the corporation may fix, in advance, a date as the record date for any such determination of stockholders. Such date shall be not more than sixty (60) nor less than ten (10) days before the date of such meeting, nor more than sixty (60) days prior to any other action. If no record date is fixed for the determination of stockholders entitled to notice of or a vote at a meeting of stockholders, the record date shall be the close of business on the day next preceding the date on which notice is given. The record date for determining stockholders for any other purpose shall be at the close of business on the date on which the resolution of the Board of Directors relating thereto is adopted.

No proxy shall be valid after eleven months from the date of its execution, unless a longer time is expressly provided therein, but in no event shall a proxy be valid after three years from the date of execution. The presence at any meeting of any stockholder who has given a proxy shall not revoke such proxy unless the stockholder shall file written notice of such revocation with the Secretary of the meeting prior to the voting of such proxy. The instrument authorizing a proxy to act shall be exhibited to the Secretary and lodged with him if he shall so request.

Whenever any action, other than the election of directors is to be taken by vote of the stockholders, it shall be authorized by a majority of the votes cast at a meeting of stockholders by the holders of shares entitled to vote thereon, unless a greater plurality is required by the Certificate of Incorporation.

Where voting as a class or series is provided in the Certificate of Incorporation, it shall be by the proportionate vote provided in the certificate or, if no proportionate vote is so provided, then for any action other than the election of directors, by a majority of the votes cast at such meeting by the holders of shares of such class or series entitled to vote thereon.
