California Code, Health and Safety Code - HSC § 51153

In connection with loans made pursuant to this article, the agency may collect, enforce the collection of, and foreclose on any collateral securing the loans and may acquire or take possession of such collateral and sell the same at public or private sale, with or without public bidding, and otherwise deal with such collateral as may be necessary to protect the interest of the agency therein. The exercise of the powers specified in this subdivision shall be subject to any agreements with bondholders.

With respect to deposit of moneys in the fund pursuant to this section, the agency may require that any collateral provided on account thereof be lodged with a financial institution or trust company located in the state designated by the agency as custodian therefor. In the absence of such requirement the financial institution shall, if collateral is to be provided for the loan or securities purchased, upon receipt of the proceeds from the agency, enter into an agreement with the agency containing such provisions as the agency shall deem necessary to adequately identify and maintain such collateral and service the same and shall provide that such financial institution shall hold such collateral as an agent for the agency and shall be held accountable as the trustee of an express trust for the application and disposition thereof and the income therefrom solely to the uses and purposes in accordance with the provisions of such agreement. A copy of each such agreement and any revisions or supplements thereto shall be filed with the Secretary of State and no further filing or other action under the California Uniform Commercial Code or any other law of the state shall be required to perfect the security interest of the agency in such collateral or any additions thereto or substitutions therefor, and the lien and trust for the benefit of the agency so created shall be binding from and after the time made against all parties having claims of any kind in tort, contract, or otherwise against such financial institution.
