Cal. Gov. Code § 64116
In the discretion of the authority, any bonds issued under this division may be secured by a trust agreement or indenture by and between the issuer and a corporate trustee or trustees, which may be the Treasurer or any trust company or bank having the powers of a trust company within or without the state. The trust agreement, indenture, or the resolution providing for the issuance of those bonds may pledge or assign the revenues to be received from a project sponsor or pursuant to any revenue-producing contract or as pledged by the issuer pursuant to Section 64109. The indenture, trust agreement, or resolution providing for the issuance of those bonds may contain provisions for protecting and enforcing the rights and remedies of the bondholders as may be reasonable and proper and not in violation of law, including, particularly, provisions as have been specifically authorized to be included in any resolution or resolutions authorizing bonds thereof. The trust agreement or indenture may set forth the rights and remedies of the bondholders and of the trustee or trustees, and may restrict the individual right of action of bondholders. In addition to the foregoing, the indenture, trust agreement, or resolution may contain other provisions as the authority or issuer may deem reasonable and proper for the security of the bondholders.
