2001 among the Company, the guarantors (as defined therein) and The Bank of New York Mellon, as trustee (the &#8220;Trustee&#8221;), as
supplemented from time to time, and as further supplemented by a twenty-fourth supplemental indenture dated as of May 6, 2026 between
the Company and the Trustee (collectively, the &#8220;Indenture&#8221;). The Indenture contains covenants that, among other things, will
limit the ability of (i) the Company and certain of its subsidiaries to create certain liens and enter into certain sale and leaseback
transactions and (ii) the Company to consolidate, merge or transfer all or substantially all of the Company&#8217;s assets on a consolidated
basis. The Indenture provides for customary events of default. Upon a change of control triggering event (as defined in the Indenture),
the Company will be required to make an offer to purchase the Notes at a price equal to 101% of their principal amount plus accrued and
unpaid interest to the repurchase date.</p>

after 4:15 p.m., New York City time (or after such time as yields on U.S. government securities are posted daily by the Board of Governors

under the caption &ldquo;U.S. government securities&ndash;Treasury constant maturities&ndash;Nominal&rdquo; (or any successor caption

the Treasury constant maturity on H.15 exactly equal to the period from the Redemption Date to the Par Call Date (the &ldquo;Remaining
Life&rdquo;); or (2)&nbsp;if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields &ndash;
one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury
constant maturity on H.15 immediately longer than the Remaining Life &ndash; and shall interpolate to the Par Call Date on a straight-line

such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity

Date H.15 TCM is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual
equivalent yield to maturity at 11:00 a.m., New York City time, on the second business day preceding such Redemption Date of the United
States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date, as applicable. If there is no United States
Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date equally
distant from the Par Call Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call
Date, the Company shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two
or more United States Treasury securities maturing on the Par Call Date or two or more United States Treasury securities meeting the criteria
of the preceding sentence, the Company shall select from among these two or more United States Treasury securities the United States Treasury
security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities
at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield
to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as
a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal
places.</P>
