Okla. Stat. tit. 18, § 1075
EXCEPTION TO REQUIREMENTS OF NOTICE
B. Whenever notice is required to be given pursuant to any provision of the Oklahoma General Corporation Act or the certificate of incorporation or bylaws of any corporation, to any shareholder or, if the corporation is a nonstock corporation, to any member to whom:
2. all , and at least two, payments, if sent by first-class mail, of dividends or interest on securities during a twelve-month period, have been mailed addressed to such person at his address as shown on the records of the corporation and
have been returned undeliverable, the giving of such notice to such person shall not be required. Any action or meeting which shall be taken or held without notice to such person shall have the same force and effect as if such notice had been duly given. If any such person shall deliver to the corporation a written notice setting forth his then current address, the requirement that notice be given to such person shall be reinstated. In the event that the action taken by the corporation is such as to require the filing of a certificate under any of the other sections of the Oklahoma General Corporation Act, the certificate need not state that notice was not given to persons to whom notice was not required to be given pursuant to the provisions of this subsection.
