in each case in a way which would materially and adversely affect the interests of bondholders, we must first notify the rating agencies of the proposed amendment, modification, waiver, supplement, termination or - 79 -

surrender and satisfy the rating agency condition. Upon satisfaction of the rating agency condition, we must thereafter notify the trustee in writing, and the trustee will be required to notify
the bondholders of the proposed amendment, modification, waiver, supplement, termination or surrender and whether the rating agency condition has been satisfied with respect thereto. The trustee will consent to this proposed amendment, modification,
supplement or waiver only with the written consent of the holders of a majority of the outstanding principal amount of the bonds of the tranches materially and adversely affected thereby. In determining whether a majority of holders have consented,
bonds owned by us, SCE or any affiliate of us shall be disregarded, except that, in determining whether the trustee shall be protected in relying upon any such consent, the trustee shall only be required to disregard any bonds it actually knows to
be so owned.

Modifications to the Sale Agreement, the Administration Agreement and the Servicing Agreement

With the prior written consent of the trustee, the sale agreement, the administration agreement and the servicing agreement may be amended,
modified, waived, supplemented, terminated, or surrendered so long as the rating agency condition is satisfied in connection therewith, at any time and from time to time, without the consent of the bondholders. However, any such amendment may not
adversely affect the interest of any bondholder in any material respect without the consent of the holders of a majority of the outstanding principal amount of the bonds. In determining whether a majority of holders have consented, bonds owned by
us, SCE or any affiliate of us shall be disregarded, except that, in determining whether the trustee shall be protected in relying upon any such consent, the trustee shall only be required to disregard any bonds it actually knows to be so owned.
