 If an event of default occurs and is continuing, the mortgage trustee may:

| • |     | take possession of the trust estate and hold, use, operate, manage and control the same; |

| • |     | sell the trust estate; and |

| • |     | enforce its rights and the rights of the mortgage bondholders by appropriate judicial proceeding at law or in 
 equity. (Article IV, Section 3)                                                                               |

The holders of a majority in aggregate principal amount of outstanding mortgage bonds have the right to direct the method and place of conducting all proceedings for the sale of the trust estate, foreclosure or appointment of a receiver or other proceedings under the mortgage. (Article VI, Section 15) The holders of not less than a majority in principal amount, upon providing reasonable security and indemnity to the mortgage trustee, can require the mortgage trustee to take action toward the execution or enforcement of the trusts created by the mortgage. (Article VI, Section 16; Article XII, Section 1(b)(8)) No holder of any mortgage bond will have the right to institute any proceeding for the foreclosure of the mortgage or for the enforcement of any other remedy under the mortgage unless:

| • |     | such holder has previously given the mortgage trustee notice of default; |

| • |     | the holders of 25% in principal amount of outstanding mortgage bonds have requested the mortgage trustee, and 
 afforded it a reasonable opportunity, to institute such proceeding in its own name;                           |

| • |     | such holder or holders have offered the mortgage trustee adequate security and indemnity against costs, expenses 
 and liabilities; and                                                                                             |

| • |     | the mortgage trustee has refused or neglected to comply with such request within a reasonable time. 
 (Article VI, Section 18)                                                                            |

No holder of mortgage bonds will have any right in any manner to affect, disturb or prejudice the lien of the mortgage. (Article VI, Section 18) Nothing in the mortgage, however, will affect or impair the right of any bondholder, which is absolute and unconditional, to enforce payment of the principal and interest of such holder’s bonds. (Article VI, Section 18) The laws of the various states in which the trust estate is located may limit or deny the ability of the mortgage trustee to enforce certain rights and remedies provided in the mortgage in accordance with their terms. 15
