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”).

In addition, Holders may not be entitled to require the Company to purchase their Notes in certain circumstances involving a significant change in the composition of the Company’s Board of Directors, including in connection with a proxy contest where the Company’s Board of Directors does not approve a dissident slate of directors but approves them as required by clause (4) of Section 1.1(e)(iv).

(e)    Notwithstanding this Section 2.13, a transaction will not be deemed to involve a Change of Control under clause (2) of Section 1.1(e)(iv) if (i) the Company becomes a direct or indirect wholly-owned subsidiary of a holding company and (ii) (A) the direct or indirect holders of the Voting Stock of such holding company immediately following that transaction are substantially the same as the holders of the Company’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 Voting Stock of such holding company.

(f)    The Company will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Change of Control. To the extent that the provisions of any securities laws or regulations conflict with the Change of Control provisions of the Indenture, the Company will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under the Change of Control provisions of the Indenture by virtue of such compliance.

The Notes are subject to redemption at the Company’s option, in whole or in part, at any time prior to February 24, 2025, at a redemption price equal to the greater of (i) 100% of the principal amount to be redeemed plus accrued and unpaid interest thereon to, but excluding, the Redemption Date, and (ii) the sum, as determined by an Independent Investment Banker, of the present values of the remaining scheduled payments of principal and interest on the Notes to be redeemed (exclusive of interest accrued to, but excluding, the Redemption Date) that would be due if the Notes matured on February 24, 2025 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 50 basis points plus accrued and unpaid interest on the principal amount being redeemed to, but excluding, the Redemption Date.

Commencing on February 24, 2025, the Company may redeem the Notes, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the principal amount of the Notes being redeemed plus accrued and unpaid interest on the principal amount being redeemed to, but excluding, the Redemption Date.

For purposes of determining the optional redemption price, the following definitions are applicable:

“Comparable Treasury Issue” means the United States Treasury security selected by an Independent Investment Banker as having a maturity comparable to the remaining term (“Remaining Life”) of the Notes to be redeemed (assuming that the Notes matured on February 24, 2025) 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 Notes.

“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 such Reference Treasury Dealer Quotations, or (2) if the Independent Investment Banker obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such Quotations or, if only one such Quotation is obtained, such Quotation.

A-4

“Independent Investment Banker” means an independent investment banking institution of national standing appointed by the Company, which may be one of the Reference Treasury Dealers.

“Reference Treasury Dealer” means (1) BofA Securities, Inc., Citigroup Global Markets Inc. and ▇.▇. ▇▇▇▇▇▇ Securities LLC, and their respective successors, and (2) any other primary U.S. government securities dealer in New York City that the Company selects (each, a “Reference Treasury Dealer”).

“Reference Treasury Dealer Quotation” means with respect to each Reference Treasury Dealer and any Redemption Date for the Notes, the average, as determined by the Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue for the Notes (expressed in each case as a percentage of its principal amount) quoted in writing to the Independent Investment Banker by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third Business Day preceding such Redemption Date.

“Treasury Rate” means with respect to any Redemption Date, (1) the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15” or any successor publication which is published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities,” for the maturity corresponding to the Comparable Treasury Issue (if no maturity is within three months before or after the Remaining Life, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue shall be determined and the Treasury Rate shall be interpolated or extrapolated from such yields on a straight line basis, rounding to the nearest month), (2) if the period from the Redemption Date to the maturity date of the notes to be redeemed is less than one year, the weekly average yield on actually traded United States Treasury securities adjusted to a constant maturity of one year will be used, or (3) if such release (or any successor release) is not published during the week preceding the calculation date or does not contain such yields, the rate per annum equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for such Redemption Date. The Treasury Rate shall be calculated on the third Business Day preceding the redemption date.

Notice of any redemption shall be mailed at least 30 days but not more than 60 days before the Redemption Date to each registered Holder of the Notes to be redeemed. If money sufficient to pay the redemption price of all of the Notes (or portions thereof) to be redeemed on the Redemption Date is deposited with the Trustee or Paying Agent on or before the Redemption Date, and unless the Company defaults in payment of the redemption price, on and after the Redemption Date, interest shall cease to accrue on the Notes or portions of the Notes called for redemption. If fewer than all of the Notes are to be redeemed, and such Notes are at the time represented by a Global Security, the Depositary shall select by lot the particular interests to be redeemed. If the Company elects to redeem fewer than all of the Notes, and any of such Notes are not represented by a Global Security, then the Trustee shall select the particular Notes to be redeemed in a manner it deems appropriate and fair (and the Depositary shall select by lot the particular interests in any Global Security to be redeemed).
