Notwithstanding the foregoing, each holder of first mortgage bonds has the right, which is absolute and unconditional, to receive payment of the principal of, premium, if any, and interest on such first mortgage bond when due and to institute suit for the enforcement of any such payment, and such rights may not be impaired without the consent of such holder.

The mortgage indenture provides that the mortgage trustee must give the holders notice of any default under the mortgage indenture to the extent required by the Trust Indenture Act of 1939, unless such default shall have been cured or waived, except that no such notice to holders of a default of the character described in the fourth bullet point under “— Mortgage Events of Default” may be given until at least 45 days after the occurrence thereof. The Trust Indenture Act of 1939 permits the mortgage trustee to withhold notices of default (except for notices of certain payment defaults) if the mortgage trustee in good faith determines the withholding of such notice to be in the interest of the holders. We are required to deliver to the mortgage trustee each year a certificate as to whether or not, to the knowledge of the officer signing such certificate, we are in compliance with the conditions and covenants under the mortgage indenture.

As a condition precedent to certain actions by the mortgage trustee at the request or direction of bondholders, the mortgage trustee may require indemnity reasonably satisfactory to it against costs, expenses and liabilities to be incurred in connection therewith.

#### Modification of the Mortgage Indenture
Without the consent of any holders of the first mortgage bonds, we and the mortgage trustee may enter into one or more supplemental indentures for any of the following purposes:

•

to evidence the succession of another person to us and the assumption by any such successor of our covenants in the mortgage indenture and in the first mortgage bonds;

•

to add one or more covenants or other provisions for the benefit of all holders or for the benefit of such holders of, or to remain in effect only so long as there shall be outstanding, first mortgage bonds of one or more specified series, or one or more tranches thereof, or to surrender any right or power conferred upon us by the mortgage indenture;
