Corp. Code, § 604

(a) Any form of proxy or written consent distributed to 10 or more shareholders of a corporation with outstanding shares held of record by 100 or more persons shall afford an opportunity on the proxy or form of written consent to specify a choice between approval and disapproval of each matter or group of related matters intended to be acted upon at the meeting for which the proxy is solicited or by such written consent, other than elections to office, and shall provide, subject to reasonable specified conditions, that where the person solicited specifies a choice with respect to any such matter the shares will be voted in accordance therewith.

(b) In any election of directors, any form of proxy in which the directors to be voted upon are named therein as candidates and which is marked by a shareholder “withhold” or otherwise marked in a manner indicating that the authority to vote for the election of directors is withheld shall not be voted for the election of a director.

(c) Failure to comply with this section shall not invalidate any corporate action taken, but may be the basis for challenging any proxy at a meeting and the superior court may compel compliance therewith at the suit of any shareholder.

(d) This section does not apply to any corporation with an outstanding class of securities registered under Section 12 of the Securities Exchange Act of 1934 or whose securities are exempted from such registration by Section 12(g)(2) of that act.
