 of a precise definition of the term “adequate protection” and the broad discretionary powers of a bankruptcy court, it is impossible to predict (1) how long payments under the bonds
could be delayed following commencement of a bankruptcy case, (2) whether or when the indenture trustee could repossess or dispose of the pledged assets or (3) whether or to what extent holders of the bonds would be compensated for any
delay in payment or loss of value of the pledged assets through the requirement of “adequate protection.”

The ability of the indenture trustees to effectively liquidate the collateral and the value received could be impaired or impeded by the need to obtain regulatory consents.

While we have all necessary consents to grant the security interests created by the first mortgage bond indenture, any foreclosure thereon
could require additional approvals that have not been obtained from California or federal regulators. We cannot assure you that these approvals could be obtained by the indenture trustees on a timely basis or at all.

USE OF PROCEEDS
