with respect to the Notes, unless the Company shall have exercised its right pursuant to Section 4.1 hereof to redeem the Notes, the Company shall make an offer to each Holder of the Notes to repurchase all or, at such Holder’s option, any
part (equal to $2,000 or any integral multiple of $1,000 in excess thereof) of such Holder’s Notes (the “Change of Control Offer”) for payment in cash equal to 101% of the aggregate principal amount of the Notes repurchased
plus accrued and unpaid interest, if any, on the Notes repurchased to, but not including, the date of purchase (the “Change of Control Payment”). 
 (b) Within 30 days following any Change of Control Triggering Event with respect to the Notes or, at the Company’s option, prior to any Change of Control but after the public announcement of the transaction or
transactions that constitutes or may constitute a Change of Control, the Company shall cause a notice to be mailed to Holders of the Notes, with a copy to the Trustee for the Notes, describing the transaction or transactions that constitute or may
constitute the Change of Control Triggering Event and offering to repurchase the Notes on the date specified in the notice, which date shall be no earlier than 30 days and no later than 60 days from the date such notice is mailed (the
“Change of Control Payment Date”), pursuant to the procedures required by the Notes and described in such notice. The notice shall, if mailed prior to the date of consummation of the Change of Control, state that the offer to
purchase is conditioned on the Change of Control Triggering Event occurring on or prior to the Change of Control Payment Date. Upon 10 Business Days’ advance notice to the Trustee, the Company may request the Trustee to mail the notice to
Holders described in this Section 2.8(b) in the name of and at the expense of the Company. 
 (c) The Company shall comply with the
requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with the repurchase of Notes as a result of a Change of Control
Triggering Event. To the extent that the provisions of any such securities laws or regulations conflict with this Section 2.8, the Company shall comply with those securities laws and regulations and shall not be deemed to have breached its
obligations under this Section 2.8 by virtue of such conflict. 
 (d) On the Change of Control Payment Date, the Company shall, to the
extent lawful: 
 (i) accept for payment all Notes or portions of Notes properly tendered pursuant to the Change of Control
Offer; 
 (ii) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes or
portions of Notes properly tendered; and 
 (iii) deliver or cause to be delivered to the Trustee the Notes properly accepted
together with an Officer’s Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Company. 
 (e) The Paying Agent shall promptly mail, to each Holder who properly tendered Notes, the purchase price for such Notes, and the Trustee shall promptly authenticate and mail (or cause to be transferred by book entry) to each such Holder a
new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided that each new Note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof.

 (f) The Company shall not be required to make a Change of Control Offer upon a Change of Control
Triggering Event if a third party makes a Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Third Supplemental Indenture applicable to a Change of Control Offer made by the
Company and purchases all Notes properly tendered and not withdrawn under such Change of Control Offer. In the event that such third party terminates or defaults on its Change of Control Offer, the Company shall be required to make a Change of
Control Offer treating the date of such termination or default as though it were the date of the Change of Control Triggering Event. 
 (g)
The Company shall not be required to purchase any Notes if there has occurred and is continuing on the Change of Control Payment Date an Event of Default under the Indenture, other than a default in the payment of the Change of Control Payment.

 COVENANTS

 Section 3.1. Limitations on Liens. The Company shall not (nor shall it permit any of its Significant Subsidiaries to) create
or permit to exist any Lien on any Principal Property of the Company or any of its Significant Subsidiaries (or on any Capital Stock of a Significant Subsidiary), whether such Principal Property or Capital Stock is now existing or owned or hereafter
acquired, to secure any Indebtedness, unless the Company shall contemporaneously secure the Notes (together with, if the Company so determines, any other Indebtedness of or guaranty by the Company or such Significant Subsidiary then existing or
thereafter created which is not subordinated to the Notes) equally and ratably with (or, at the Company’s option, prior to) such secured Indebtedness. 
 The foregoing restriction, however, shall not require the Company to secure the Notes if the Lien consists of either of the following: 
 (a) Permitted Liens; or 
 (b) Liens securing Indebtedness if at the time of determination, after giving pro
forma effect to the incurrence, creation, assumption or guaranty of such Indebtedness or the securing of outstanding Indebtedness and to the retirement of Indebtedness which is concurrently being retired, the sum of (without duplication)
(i) the aggregate principal amount of all Indebtedness of the Company and its Subsidiaries secured by Liens (other than Permitted Liens) and (ii) all Attributable Debt in respect of Sale and Lease-Back Transactions not otherwise permitted
under the first sentence of Section 3.2 hereof, does not exceed fifteen percent of Consolidated Net Tangible Assets. 
 Section 3.2. Limitation on Sale and Lease-Back Transactions. The Company shall not, and shall not permit any of its Significant Subsidiaries to, enter into any Sale and Lease-Back Transaction with respect to any Principal

square feet, or (ii) the land, improvements, buildings and fixtures located at One North End Ave, New York, New York 10282, (y) any such Sale and Lease-Back Transaction involving a lease for a term of not more than three years or
(z) any such Sale and Lease-Back Transaction between the Company and one of its Subsidiaries or between its Subsidiaries, unless: 
 (a)
the Company or such Significant Subsidiary, as applicable, could have incurred Indebtedness secured by a Lien on the Principal Property involved in such Sale and Lease-Back Transaction in an amount at least equal to the Attributable Debt with
respect to such Sale and Lease-Back Transaction, without equally and ratably securing the Notes, pursuant to Section 3.1 hereof; or 
  

 10 








 (b) the proceeds of such Sale and Lease-Back Transaction are at least equal to the fair market value of
the affected Principal Property (as determined in good faith by the Company’s Board of Directors) and the Company applies an amount equal to the net proceeds of such Sale and Lease-Back Transaction within 365 days of such Sale and Lease-Back
Transaction to any (or a combination) of: 
 (i) the prepayment or retirement of the Notes, 
 (ii) the prepayment or retirement (other than any mandatory retirement, mandatory prepayment or sinking fund payment or by payment at
maturity) of other Indebtedness of the Company or of one of its Subsidiaries (other than Indebtedness that is subordinated to the Notes or Indebtedness owed to the Company or one of its Subsidiaries) that matures more than 12 months after its
creation; or 
 (iii) the purchase, construction, development, expansion or improvement of other comparable property.

Transaction if, after giving pro forma effect to such Sale and Lease-Back Transaction, the sum of (without duplication) (i) the aggregate principal amount of all Indebtedness of the Company and its Subsidiaries secured by Liens (other than
Permitted Liens) and (ii) all Attributable Debt in respect of Sale and Lease-Back Transactions not otherwise permitted under the first sentence of this Section 3.2, does not exceed fifteen percent of Consolidated Net Tangible Assets.

 (i) 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the Redemption Date; or 
 (ii) the sum of the present values of the Remaining Scheduled Payments of principal and interest in respect of the Notes to be redeemed discounted to the

appropriate; provided that if at the time of redemption the Notes to be redeemed are registered as one or more Global Securities, the Depositary shall determine, in accordance with its procedures, the principal amount of the Notes to be
redeemed held by each Holder of such Notes. 
 (b) Notice of any redemption pursuant to this Section 4.1 shall be given as provided in
Section 1104 of the Base Indenture, except that any notice of such redemption shall not specify the related Optional Redemption Price

redemption to each Holder of Notes in accordance with Section 1104 of the Base Indenture. If funds sufficient to pay the Special Mandatory Redemption Price (including any accrued and unpaid interest) of all of the Notes to be redeemed on the
Special Mandatory Redemption Date are deposited with the Paying Agent on or before 10:00 a.m., New York City time, on the Special Mandatory Redemption Date, the Notes shall cease to accrue interest on and after the Special Mandatory Redemption Date,

 [FORM OF REVERSE OF SECURITY] 
 This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued
in one or more series under a Senior Debt Indenture, dated as of August 12, 2008 (the “Base Indenture”), as supplemented by the Third Supplemental Indenture, dated as of August 12, 2008 (the “Supplemental
Indenture” and, together with the Base Indenture, the “Indenture”), between the Company and U.S. Bank National Association, as Trustee (herein called the “Trustee,” which term includes any successor trustee
under the Indenture), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon
which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof initially limited in aggregate principal amount to $750,000,000, provided that the Company may, without the
consent of any Holder, at any time and from time to time increase the initial principal amount. 
 The Securities of this series are subject
to redemption as provided in Sections 4.1 and 4.2 of the Supplemental Indenture and Article XI of the Base Indenture. 
 This Security will
not be subject to any sinking fund. 
 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, and premium, if any, plus accrued and
unpaid interest on 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 not less than a majority 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 reasonable indemnity, 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. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or any premium or interest hereon on or after
the respective due dates expressed herein. 
 No reference herein to the Indenture and no provision of this Security or of the Indenture
