The Securities may be issued in one or more series, which different series may be issued in various aggregate principal amounts, may mature at different times, may bear interest (if any) at different rates, may be subject to different redemption provisions (if any), may be subject to different sinking, purchase or analogous funds (if any) and may otherwise vary as in the Indenture provided. This Note is one of a series of Securities designated as the 4.450% Senior Notes due 2023 of the Issuer, initially limited in aggregate principal amount to $300,000,000 (the “Notes”). The Issuer may, without notice to or the consent of the Holders of the Outstanding Notes, issue additional Securities of the same tenor as the Notes so that such additional Securities and the Outstanding Notes shall form a single series of Securities under the Indenture.

In case an Event of Default with respect to the 4.450% Senior Notes due 2023, as defined in the Indenture, shall have occurred and be continuing, the principal hereof may be declared, and upon such declaration shall become, due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture.

The Indenture contains provisions permitting the Issuer and the Trustee, with the consent of the holders of not less than a majority in aggregate principal amount of the Securities at the time Outstanding (as defined in the Indenture) of all series to be affected (voting as one class), evidenced as in the Indenture provided, to execute supplemental indentures adding any provisions to or changing in any manner or eliminating any of the provisions of the Indenture or of any supplemental indenture or modifying in any manner the rights of the holders of the Securities of each such series; provided, that no such supplemental indenture shall (i) extend the final maturity of any Security, or reduce the principal amount thereof, reduce the rate or extend the time of payment of interest thereon, or reduce any amount payable on redemption thereof or make the principal thereof (including any amount in respect of original issue discount), or interest thereon payable in any coin or currency other than that provided in the Securities or in accordance with the terms thereof, or reduce the amount of the principal of an Original Issue Discount Security that would be due and payable upon an acceleration of the maturity thereof pursuant to Section 4.1 of the Indenture or the amount thereof provable in bankruptcy pursuant to Section 4.2 of the Indenture or impair or affect the right of any Securityholder to institute suit for the payment thereof or any right of repayment at the option of the Securityholder, in each case without the consent of the holder of each Security so affected, or (ii) reduce the percentage in principal amount of Securities of any series, the consent of the holders of which is required for any such supplemental indenture or the consent of whose holders is required for any waiver of compliance with certain provisions of the Indenture or certain defaults under the Indenture and their consequences, provided for in the Indenture, without the consent of the holders of each Security so affected.

5

It is also provided in the Indenture that, with respect to certain defaults or Events of Default regarding the Securities of any series, prior to a declaration of the acceleration of the maturity of such Securities, the holders of a majority in aggregate principal amount of the Securities of such series at the time Outstanding (each such series voting as a separate class) may on behalf of the holders of all the Securities of such series waive any such past default or Event of Default and its consequences. The preceding sentence shall not, however, apply to a default in respect of a covenant or provision of the Indenture which cannot be modified or amended without the consent of the holder of each Security affected as provided in Section 7.2 of the Indenture. Any such consent or waiver by the holder of this Note shall be conclusive and binding upon such holder and upon all future holders and owners of this Note and any Notes which may be issued in exchange or substitution herefor, irrespective of whether or not any notation thereof is made upon this Note or such other Notes.

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Issuer, which is absolute and unconditional, to pay the principal of and any premium and interest on this Note in the manner, at the respective times, at the rate and in the coin or currency herein prescribed.

If the Issuer does not complete the MEI Acquisition on or before June 13, 2014 (the “Special Redemption Deadline”), or if the MEI Stock Purchase Agreement is terminated prior to such Special Redemption Deadline, the Issuer shall redeem all Outstanding Notes on the Special Redemption Date (such redemption, a “Special Redemption”) at the Special Redemption Price.

The Issuer shall deliver notice of a Special Redemption promptly after the occurrence of the event triggering such Special Redemption to the registered address of each holder, with a copy to the Trustee. If funds sufficient to pay the Special Redemption Price of all Notes to be redeemed on the Special Redemption Date are deposited with the Paying Agent on or before such Special Redemption Date, and the applicable conditions of the Indenture are satisfied, on and after such Special Redemption Date, the Notes shall cease to bear interest and all rights under the Notes shall terminate.

plus, in each case, accrued and unpaid interest on the Notes being redeemed to but excluding the applicable date of redemption. The provisions of Article Eleven of the Indenture shall apply to any redemption of the Notes.

“Treasury Rate” means, with respect to any date of redemption, the yield to maturity at the time of computation of United States Treasury securities with a constant maturity (as compiled and published in the most recent Federal Reserve Statistical Release H.15 (519) which has become publicly available at least two Business Days prior to such date of redemption (or, if such Statistical Release is no longer published, any publicly available source or similar market data)) most nearly equal to the period from such date of redemption to the maturity date; provided, however, that if the period from such date of redemption to the maturity date is not equal to the constant maturity of a United States Treasury security for which a weekly average yield is given, the Treasury Rate shall be obtained by linear interpolation (calculated to the nearest one-twelfth of a year) from the weekly average yields of United States Treasury securities for which such yields are given, except that if the period from such date of redemption to the maturity date is less than one year, the weekly average yield on actually traded United States Treasury securities adjusted to a constant maturity of one year shall be used.

Notice of any redemption will be mailed at least 30 days but not more than 60 days before the redemption date to each holder of the Notes to be redeemed. Unless the Issuer defaults in payment of the redemption price, on and after the redemption date, interest will cease to accrue on the Notes or portions thereof called for redemption.

plus accrued and unpaid interest, if any, on the Notes repurchased, to the date of purchase (the “Change of Control Payment”). Within 30 days following any Change of Control Triggering Event or, at the Issuer’s option, prior to any Change of Control, but after the public announcement of the Change of Control, the Issuer will mail a notice to holders describing the transaction or transactions that constitute or would constitute a Change of Control Triggering Event and offering to repurchase the Notes on the date specified in the notice, which date will 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 described in such notice.

To the extent that the provisions of any securities laws or regulations conflict with the Issuer’s obligations to repurchase the Notes upon a Change of Control Triggering Event, the Issuer will comply with the applicable securities laws and regulations and will not be deemed to have breached our obligations by virtue of such conflict.

On the Change of Control Payment Date, the Issuer will, to the extent lawful:

(2) 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

The Issuer will not be required to make a Change of Control Offer upon a Change of Control Triggering Event if a third party (1) makes the Change of Control Offer in the manner, at the time and otherwise in compliance with the requirements applicable to a Change of Control Offer made by the Issuer and (2) purchases all Notes properly tendered and not withdrawn under the Change of Control Offer. A Change of Control Offer may be made in advance of a Change of Control Triggering Event, if a definitive agreement is in place for a Change of Control at the time of the making of a Change of Control Offer.

For purposes of this provision, the following terms will have the meanings set forth below:

“Below Investment Grade Rating Event” means that the Notes are rated below an Investment Grade Rating by each of the Rating Agencies on any date from the date of the public notice of an arrangement that could result in a Change of Control until the end of the 60-day period following public notice of such arrangement (which 60-day period shall be extended so long as the rating of such series of the Notes is under publicly announced consideration for possible downgrade by any of the Rating Agencies); provided that a Below Investment Grade Rating Event otherwise arising by virtue of a particular reduction in rating shall not be deemed to have occurred in respect of a particular Change of Control (and thus shall not be deemed a Below Investment Grade Rating Event for purposes of the definition of Change of Control Triggering Event hereunder) if the Rating Agencies making the reduction in rating to which this definition would otherwise apply do not announce or publicly confirm or inform the Trustee in writing at its request that the reduction from an Investment Grade Rating to a below Investment Grade Rating was the result, in whole or substantially in part, of any event or circumstance comprised of or arising as a result of, or in respect of, the applicable Change of Control (whether or not the applicable Change of Control shall have occurred at the time of the Below Investment Grade Rating Event).

“Change of Control” means the occurrence of any of the following:

(1) the direct or indirect sale, lease or exchange (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 Issuer and the Issuer’s subsidiaries taken as a whole to any “person” (as that term is used in Section 13(d)(3) of the Securities Exchange Act of 1934, as amended) other than the Issuer or one of the Issuer’s subsidiaries;

(2) the adoption of a plan relating to the liquidation or dissolution of the Issuer (other than in a transaction that complies with the covenant described under Article 8 of the Indenture); or

(3) the consummation of any transaction (including, without limitation, any merger or consolidation) the result of which is that any “person” (as defined above), becomes the beneficial owner, directly or indirectly, of more than 50% of the Issuer’s Voting Stock, measured by voting power rather than number of shares.

Notwithstanding the foregoing, a transaction described in clause (3) above will not be deemed to involve a “Change of Control” if (1) the Issuer becomes a direct or indirect wholly owned subsidiary of a holding company and (2)(A) the direct or indirect holders of the Voting Stock of such holding company immediately following that transaction are substantially the same as, and hold in substantially the same proportions as, the holders of the Issuer’s Voting Stock immediately prior to that transaction or (B) immediately following that transaction no person (other than a holding company satisfying the requirements of this sentence) is the beneficial owner, directly or indirectly, of more than 50% of the then-outstanding Voting Stock, measured by voting power, of such holding company.

“Change of Control Triggering Event” means the occurrence of both a Change of Control and a Below Investment Grade Rating Event.

“Voting Stock” of any specified person as of any date means the Common Stock of such person that is at the time entitled to vote generally in the election of the board of directors of such person.

The Notes will not be entitled to the benefit of any sinking fund.

The Notes are issuable in registered form without coupons at the office or agency of the Issuer in the Borough of Manhattan, The City of New York, and in the manner and subject to the limitations provided in the Indenture, but without the payment of any service charge, Notes may be exchanged for a like aggregate principal amount of Notes of other authorized denominations.

Upon due presentation for registration of transfer of this Note at the office or agency of the Issuer in the Borough of Manhattan, The City of New York, a new Note or Notes of authorized denominations for an equal aggregate principal amount will be issued to the transferee in exchange therefor, subject to the limitations provided in the Indenture, without charge except for any tax or other governmental charge imposed in connection therewith.

The Issuer, the Trustee and any agent of the Issuer or the Trustee may deem and treat the registered holder hereof as the absolute owner of this Note (whether or not this Note shall be overdue and notwithstanding any notation of ownership or other writing hereon), for the purpose of receiving payment of, or on account of, the principal hereof and premium, if any, and subject to the provisions on the face hereof, interest hereon, and for all other purposes, and neither the Issuer nor the Trustee nor any agent of the Issuer or the Trustee shall be affected by any notice to the contrary.
