Cal. MVC § 483.8

A resolution of issuance may include provisions prescribing a procedure by which the terms and conditions of the resolution may be subsequently amended or modified with the consent of the department and the California National Guard Finance Committee and the vote or written consent of the holders of a specified principal amount or specified proportion of the revenue bonds issued and outstanding. Such provisions may include provisions for meetings of revenue bond holders and for the manner in which the consent of the revenue bondholders may be given. A resolution of issuance may provide that the revenue bonds held by the department or by the State of California or any political subdivision, public corporation, or agency thereof shall not be counted as outstanding revenue bonds or be entitled to vote or consent, but shall nevertheless be subject to any such modification or amendment.
