California Code, Food and Agricultural Code (Formerly Agricultural Code) - FAC § 54122

The bylaws may prescribe the manner of determining the value of a member's interest and provision for its purchase by the association upon the death or withdrawal of a member or upon the expulsion of a member or forfeiture of his membership, or at the option of the association, the purchase at a price fixed by conclusive appraisal by the board of directors; and the conditions and terms for the repurchase by the association from its stockholders of their stock upon their disqualification as stockholders. In case of the expulsion of a member, and where the bylaws do not provide any procedure or penalty, the board of directors shall equitably and conclusively appraise his property interest in the association and shall fix the amount of his property interest in money, which shall be paid to him within one year after such expulsion.
