    § 2.1.     There shall be a
        thirty-first series of Bonds under the Indenture, known as and entitled “First Mortgage Bonds, Series NNN due 2052” or “First Mortgage Bonds, Series NNN” (herein and in the Indenture referred to as the “2052 Series NNN Bonds”), and the form thereof shall contain suitable provisions with respect to the matters hereinafter in this Section specified and shall in other respects be substantially as set forth in Exhibit A
        to the Indenture.

     

    The aggregate principal amount of 2052 Series NNN Bonds which may be authenticated and delivered and outstanding under the Indenture is
      $125,000,000.

     

    

    
      12

      
        


    

    The 2052 Series NNN Bonds shall be payable to the Collateral Agent, and shall be nontransferable except to a successor of the Collateral
      Agent, in accordance with the Note Purchase Agreement.

     

    The 2052 Series NNN Bonds shall bear interest at the rate of 5.47% per annum, computed on the basis of a 360-day year of twelve 30-day
      months, until the principal thereof is paid or made available for payment, and shall mature on October 24, 2052, subject to prior redemption as described herein; provided that any principal, Make-Whole Amount (as defined in the Note Purchase
      Agreement), and any such installment of interest which is overdue shall bear interest at a rate of interest that is the greater of (i) 7.47% per annum or (ii) 2.00% per annum over the rate of interest publicly announced by PNC Bank, National
      Association as its “base” or “prime” rate (to the extent that payment of such interest is enforceable under applicable law).

     

    The 2052 Series NNN Bonds shall be in the form of registered Bonds without coupons of denominations of $1,000 and any integral multiple
      thereof which may be authorized by the Company, the issue of a registered Bond without coupons in any such denomination to be conclusive evidence of such authorization.  Any 2052 Series NNN Bonds shall be dated (i) as of the semi-annual interest
      payment date (as specified in the first paragraph of the 2052 Series NNN Bonds) next preceding the date on which such 2052 Series NNN Bonds shall be authenticated, unless such 2052 Series NNN Bonds are authenticated before April 24, 2023, in which
      case such 2052 Series NNN Bonds shall be dated October 24, 2022 or, (ii) if such date of authentication shall be an interest payment date, such 2052 Series NNN Bonds shall be dated such interest payment date; provided, however, that, if at the time of authentication of any 2052 Series NNN Bonds interest is in default on the 2052 Series NNN Bonds, such 2052 Series NNN Bonds shall be dated as of the interest
      payment date to which interest has previously been paid or made available for payment on the 2052 Series NNN Bonds.  All 2052 Series NNN Bonds shall bear interest from their respective dates, such interest to be payable, upon the terms of and
      otherwise in accordance with the 2052 Series NNN Bonds, on each date on which interest shall from time to time be payable on the Series 2022C Senior Notes due October 24, 2052; provided, that the obligation of the Company to make payments with respect to the principal of, Make-Whole Amount, if any, and interest on the 2052 Series NNN Bonds shall be fully or partially, as the case may be, satisfied and
      discharged to the extent that at the time any such payment shall be due, the then due principal of, Make-Whole Amount, if any, and interest on any of the Series 2022C Senior Notes due October 24, 2052 shall have been fully or partially paid from
      payments made by the Company under the Note Purchase Agreement.  The principal of, Make-Whole Amount, if any, and interest on the 2052 Series NNN Bonds shall be payable at the principal office of the Trustee, in Edison, New Jersey, or, at the option
      of the Company, at the “principal office” (as indicated pursuant to the Note Purchase Agreement) of the Collateral Agent, in any coin or currency of the United States of America which at the time of payment shall be legal tender for the payment of
      public and private debts.

     

    

    
      13

      
        


    

    Notwithstanding any other provision of the Indenture or of the 2052 Series NNN Bonds, payments of the principal of, Make-Whole Amount, if
      any, and interest on any 2052 Series NNN Bond may be made directly to the registered holder thereof without presentation or surrender thereof or the making of any notation thereon if there shall be filed with the Trustee a Certificate of the Company
      to the effect that such registered holder (or the person for whom such registered holder is a nominee) and the Company have entered into a written agreement that payment shall be so made; provided, however, that before such registered holder
      transfers or otherwise disposes of any 2052 Series NNN Bond, such registered holder will, at its election, either endorse thereon (or on a paper annexed thereto) the principal amount thereof redeemed and the last date to which interest has been paid
      thereon or make such Bond available to the Company at the principal office of the Trustee for the purpose of making such endorsement thereon.

     

    The 2052 Series NNN Bonds shall be subject to redemption at the option of the Company or otherwise, and shall be subject to mandatory
      redemption, in the manner provided in the applicable provisions of Article Ten of the Indenture, as amended by Article III of this Twelfth Supplemental Indenture.

     

    The 2052 Series NNN Bonds shall be excluded from the benefits of, and shall not be subject to redemption through the operation of, a
      Mandatory Sinking Fund pursuant to § 11.02 of the Indenture.

     

    Notwithstanding the provisions of § 10.02 or any other provision of the Indenture, the selection of 2052 Series NNN Bonds to be redeemed
      shall, in case fewer than all of the outstanding 2052 Series NNN Bonds are to be redeemed, be made by the Trustee pro rata (to the nearest multiple of One Thousand Dollars ($1,000)) among the registered holders of the 2052 Series NNN Bonds in
      proportion, as nearly as practicable, to the respective unpaid principal amounts of 2052 Series NNN Bonds registered in the names of such holders, with adjustments, to the extent practicable, to compensate for any prior redemption not made exactly in
      such proportion (or otherwise as may be specified by a written order signed by the registered holders of all outstanding 2052 Series NNN Bonds).

     

    The definitive 2052 Series NNN Bonds may be issued in the form of engraved Bonds or Bonds printed or lithographed on steel engraved borders
      or Bonds in typed form on normal bond paper.  Subject to the foregoing provisions of this Section and the provisions of § 2.11 of the Indenture, all definitive 2052 Series NNN Bonds shall be fully exchangeable for other Bonds of the same series, of
      like aggregate principal amounts, and, upon surrender to the Trustee at its principal office, shall be exchangeable for other Bonds of the same series of a different authorized denomination or denominations, as requested by the holder surrendering
      the same.  The Company will execute, and the Trustee shall authenticate and deliver, registered Bonds without coupons, whenever the same shall be required for any such exchange.

        Bonds in the aggregate principal amount of $125,000,000 may forthwith upon the execution and delivery of this Twelfth Supplemental Indenture, or from time to time thereafter, be executed by the Company and delivered to the Trustee, and shall
        thereupon be authenticated and delivered by the Trustee upon compliance by the Company with the provisions of Articles Four, Five or Six of the Indenture, without awaiting the filing or recording of this Twelfth Supplemental Indenture.  No
        additional 2052 Series NNN Bonds shall be issued under Article Four, Five or Six of the Indenture without the consent in writing of the holders of all the outstanding 2052 Series NNN Bonds.

     

    ARTICLE III

      under this Section shall be fully or partially, as the case may be, satisfied and discharged to the extent that at any time such payment shall be due, the then due payment at maturity or redemption payment on any of the Series 2022C Senior Notes due
      October 24, 2052 shall have been fully or partially made from payments made by the Company on the Notes under the Note Purchase Agreement; provided, further, however,
      that any principal, Make-Whole Amount, and any interest which is overdue shall bear interest at a rate of interest that is the greater of (i) 7.47% per annum or (ii) 2.00% per annum over the rate of interest publicly announced by PNC Bank, National
      Association as its “base” or “prime” rate (to the extent that payment of such interest is enforceable under applicable law).  Terms used and not defined in this Section and in Section 10.66 shall have the respective meanings given to them in the
