Okla. Stat. tit. 18, § 18-1074: Waiver of notice

WAIVER OF NOTICE

Whenever notice is required to be given under any provision of

the Oklahoma General Corporation Act or of the certificate of

incorporation or bylaws, a written waiver thereof, signed by the

person entitled to notice, or a waiver by electronic transmission by

the person entitled to notice, whether before or after the time

stated therein, shall be deemed equivalent to notice. Attendance of

a person at a meeting shall constitute a waiver of notice of such

meeting, except when the person attends a 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. Neither the business to be transacted at, nor

the purpose of, any regular or special meeting of the shareholders,

directors, or members of a committee of directors need be specified

in any written waiver of notice or any waiver by electronic

transmission unless so required by the certificate of incorporation

or the bylaws.
