The net amount of rent required to be paid under any such lease for any such period is the aggregate amount of the rent payable by the lessee with respect to such period after excluding amounts required to be paid on account of maintenance and repairs, insurance, taxes, assessments, water rates and similar charges.

This Security is one of the series designated on the face hereof limited in aggregate principal amount to $400,000,000.

The Securities of this series are subject to redemption at any time, upon not less than 30 days’ and not more than 60 days’ notice by mail, as a whole or from time to time in part, at the election of the Company (provided, however, that, if the Company shall have elected pursuant to the Indenture to defease the entire Indebtedness of this Security or certain restrictive covenants and Events of Defaults with respect to this Security, prior to making such election to redeem the Securities it shall have deposited in trust amounts sufficient to pay the Redemption Price), (i) on or before November 1, 2023 at a Redemption Price equal to the greater of (A) 100% of the principal amount of such Securities to be redeemed, plus accrued interest thereon to the Redemption Date and (B) as determined by the Quotation Agent, the sum of the present values of the Remaining Scheduled Payments (as defined below) of this Security to be redeemed, discounted to the Redemption Date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined below), plus 20 basis points, plus accrued and unpaid interest thereon to the Redemption Date or (ii) after November 1, 2023 at a Redemption Price equal to 100% of the principal amount of such Securities to be redeemed, plus accrued interest thereon to the Redemption Date.

“Comparable Treasury Price” means, with respect to any Redemption Date, (1) the average of the Reference Treasury Dealer Quotations for such Redemption Date, after excluding the highest and lowest of such Reference Treasury Dealer Quotations, or (2) if the Trustee obtains fewer than four such Reference Treasury Dealer Quotations, the average of all quotations obtained.

The Indenture contains provisions for defeasance at any time of the entire Indebtedness of this Security or certain restrictive covenants and Events of Default with respect to this Security, in each case upon compliance with certain conditions set forth in the Indenture.

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of a majority in principal amount of the Securities at the time Outstanding of each series to be affected. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount of the Securities of this series at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee indemnity or security reasonably satisfactory to it, and the Trustee shall not have received from the Holders of a majority in principal amount of Securities of this series at the time Outstanding a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity.
