 [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 an Indenture, dated as of March 14, 2006 (herein called the “Indenture”, which term shall have the meaning assigned to it in such instrument), between the Company and The Bank of New York Mellon
(formerly known as The Bank of New York), 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 $300,000,000, subject to certain exceptions referred to in the Indenture. In addition, the Company may from time to time without the consent of the Holders of
Securities create and issue further securities having the same terms and conditions as the Securities in all respects (or in all respects except for the issue date and issue price) and so that such further issue shall be consolidated and form a
single series with the outstanding securities of this series (including the Securities) or upon such terms as the Company may determine at the time of their issue. References herein to the Securities include (unless the context requires otherwise)
any other securities issued as described in this paragraph and forming a single series with the Securities. 
 The Securities of
this series are subject to redemption upon not less than 30 days’ and not more than 60 days’ notice by mail, in whole or in part, at the option of the Company at any time and from time to time, at a Redemption Price equal to the greater of
(i) 100% of the principal amount of the Securities to be redeemed and (ii) the sum of the present values of the remaining scheduled payments of principal and interest in respect of the Securities to be redeemed (not including any portion
of such payments of interest accrued as of the date of redemption) discounted to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate, plus 25 basis points plus, in each case,
accrued interest thereon to the Redemption Date. 
 “Comparable Treasury Issue” means the United States Treasury
security selected by the Reference Treasury Dealers as having a maturity comparable to the remaining term of the Securities to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in
pricing new issues of corporate debt securities of comparable maturity to the remaining term of the Securities. 

“Reference Treasury Dealer” means (i) each of Barclays Capital Inc. and J.P. Morgan Securities LLC and their respective
successors unless any of them shall cease to be a primary U.S. Government securities dealer in New York City (a “Primary Treasury Dealer”), in which case the Company shall substitute another Primary Treasury Dealer, and (ii) any other
two Primary Treasury Dealers selected by the Company. 
 “Reference Treasury Dealer Quotations” means, with respect to
the Reference Treasury Dealer and any Redemption Date, the average, as determined by the Trustee, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the
Trustee by such Treasury Reference Dealer at 3:30 p.m., New York City time, on the third Business Day preceding such Redemption Date. 







 “Treasury Rate” means, with respect to any Redemption Date, the rate per annum
equal to the semiannual equivalent yield to maturity (computed as of the third business day immediately preceding that Redemption Date) of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue (expressed as a percentage
of its principal amount) equal to the Reference Treasury Dealer Quotations for that redemption date. The Treasury Rate will be calculated on the third Business Day preceding the redemption date. 

In the event of redemption of this Security in part only, a new Security or Securities of this series and of like tenor for the
unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof. 
 If a Change of
Control Triggering Event occurs, unless the Company has exercised its right to redeem the Securities, Holders of Securities will have the right to require the Company to repurchase all or a portion of the Securities pursuant to the offer described
below (a “Change of Control Offer”), at a purchase price equal to 101% of the principal amount thereof plus accrued and unpaid interest, if any, to the date of purchase, subject to the rights of Holders of Securities on the relevant record
date to receive interest due on the relevant Interest Payment Date. 
 Within 30 days following the date upon which the Change
of Control Triggering Event occurred, or at the Company’s option, prior to any Change of Control but after the public announcement of the pending Change of Control, the Company will be required to send, by first class mail, a notice to Holders
of Securities, with a copy to the Trustee, which notice will govern the terms of the Change of Control Offer. Such notice will state, among other things, the purchase date, which must be no earlier than 30 days nor later than 60 days from the date
such notice is mailed, other than as may be required by law (the “Change of Control Payment Date”). The notice, if mailed prior to the date of consummation of the Change of Control, will state that the Change of Control Offer is
conditioned on the Change of Control being consummated on or prior to the Change of Control Payment Date. Holders of Securities electing to have Securities purchased pursuant to a Change of Control Offer will be required to surrender their
Securities, with the form entitled “Option of Holder to Elect Purchase” on the reverse of the Securities completed, to the Paying Agent at the address specified in the notice, or transfer their Securities to the Paying Agent by book-entry
transfer pursuant to the applicable procedures of the Paying Agent, prior to the close of business on the third Business Day prior to the Change of Control Payment Date. 
 The Company will not be required to make a Change of Control Offer if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for such an offer made
by the Company and such third party purchases all Securities properly tendered and not withdrawn under its offer.

of any Change of

publicly announced consideration for possible downgrade by any Rating Agency).

occurrence of any one of the following: 
 (1) the direct or indirect sale, lease, transfer, conveyance or other disposition
(other than by way of merger or consolidation), in one or a series of related transactions, of all or substantially all of the assets of the Company and its subsidiaries taken as a whole to any “person” (as that term is used in
Section 13(d)(3) of the Exchange Act) other than to the Company or one of its subsidiaries; 
 (2) the consummation of any
transaction (including without limitation, any merger or consolidation) the result of which is that any “person” (as that term is used in Section 13(d)(3) of the Exchange Act) becomes the “beneficial owner” (as defined in
Rules 13d-3 and 13d-5 under the Exchange Act), directly or indirectly, of more than 50% of the outstanding Voting Stock of the Company, measured by voting power rather than number of shares; 

(3) the Company consolidates with, or merges with or into, any person, or any person consolidates with, or merges with or into, the
Company, in a transaction in which any of the outstanding Voting Stock of the Company or such other person is converted into or exchanged for cash, securities or other property, other than any such transaction where the shares of the Voting Stock of
the Company outstanding immediately prior to such transaction constitute, or are converted into or exchanged for, a majority of the Voting Stock of the surviving person immediately after giving effect to such transaction; 

(4) the first day on which the majority of the members of the board of directors of the Company cease to be Continuing Directors; or

majority of the Continuing Directors who were members of such board of directors at the time of such nomination or election. 

“Fitch” means Fitch Inc., a subsidiary of Fimalac, S.A., and its successors.

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 transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made
upon this Security.

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 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. 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 shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of
and any premium and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed.
