The provisions of Sections 202, 204 (other than subdivision (a) thereof) and 205 of the new law relating to the contents of articles do not apply to corporations existing on the effective date unless and until an amendment of the articles is filed stating that the corporation elects to be governed by all of the provisions of the new law not otherwise applicable to it under this chapter. Such amendment may be adopted by approval of the board alone, except that, if any such amendment makes any change in the articles other than conforming the statement of purposes and powers to subdivision (b) of Section 202 and the deletion of any references to par value and location of principal office and deleting any statement regarding the number of directors or conforming any such statement to Section 212 (subject to Section 2304), it shall also be approved by the outstanding shares (Section 152) if such approval is otherwise required for the changes made. The amendment shall not name the corporation’s initial agent for service of process if a report required by Section 1502 has been filed.
