                                            mutual promises and obligations contained in Section 3 of this Agreement, the Company Parties
                                            voluntarily release and forever discharge Executive, Executive’s estate, and Executive’s
                                            heirs generally from all claims, demands, debts, damages and liabilities of every name and
                                            nature, known or unknown (“Claims”) that, as of the date when Executive signs
                                            this Agreement, the Company Parties have, ever had, now claim to have or ever claimed to
                                            have had against Executive, Executive’s estate and Executive’s heirs up to signing
                                            this Agreement, except for any Claims relating to or arising out of any fraudulent or dishonest
                                            act or omission by Executive. The Company Parties represent that they have not filed, and

                                            or any administrative agency concerning any matter involving you. As a material inducement

settlement of all restricted stock unit awards that become vested as a result of Section 2(c) herein until January 1, 2023, and the Company

will be subject to the additional tax imposed under Section 409A, and any ambiguities herein will be interpreted to so comply. Notwithstanding
the foregoing, the Company makes no representations that such deferral complies with Section 409A and in no event shall the Company be
liable for all or any portion of any taxes, penalties, interest or other expenses that may be incurred by Executive on account of non-compliance
with Section 409A of the Code.

“Treasury Rate” means, with respect
to any redemption date, the yield determined by the Issuer in accordance with the following two paragraphs:

 

(i)            The
Treasury Rate shall be determined by the Issuer as of 4:15 p.m., New York City time (or as of such time as yields on U.S. government
securities are posted daily by the Board of Governors of the Federal Reserve System), on the third Business Day preceding the
redemption date based upon the yield or yields for the most recent day that appear as of such time on such day in the most recent
statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates
(Daily)—H.15” (or any successor designation or publication) (“H.15”) under the caption “U.S.
government securities–Treasury constant maturities–Nominal” (or any successor caption or heading). In determining
the Treasury Rate, the Issuer shall select, as applicable: (1) the yield for the Treasury constant maturity on H.15 exactly
equal to the period from the redemption date to the Applicable Calculation Date (the “Remaining Life”); or
(2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two yields – 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 – and shall interpolate to the Applicable Calculation
Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal
places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the
yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the
applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of
months or years, as applicable, of such Treasury constant maturity from the redemption date.

 

(ii)            If
on the third Business Day preceding the redemption date no such yield or yields appear in H.15, or H.15 or any successor designation or
publication is no longer published, the Issuer 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 Applicable Calculation Date, as applicable. If there
is no United States Treasury security maturing on the Applicable Calculation Date but there are two or more United States Treasury securities
with a maturity date equally distant from the Applicable Calculation Date, one with a maturity date preceding the Applicable Calculation
Date and one with a maturity date following the Applicable Calculation Date, the Issuer shall select the United States Treasury security
with a maturity date preceding the Applicable Calculation Date. If there are two or more United States Treasury securities maturing on
the Applicable Calculation Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Issuer
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. Prior to the applicable
redemption date, the Issuer shall file with the Trustee an Officer’s Certificate setting forth the Treasury Rate and showing the
calculation of such in reasonable detail. The Trustee will have no responsibility for the calculation of the Treasury Rate and will have
no duty to verify the Issuer’s calculation.

 

“United States” means the United
States of America, the states of the United States, and the District of Columbia.

 

“United States Dollar Equivalent”
means with respect to any monetary amount in a currency other than Dollars, at any time of determination thereof, the amount of Dollars
obtained by translating such other currency involved in such computation into Dollars at the spot rate for the purchase of Dollars with
the applicable other currency as published in the Financial Times on the date that is two Business Days prior to such determination.

 

“United States Person” means any
individual who is a citizen or resident of the United States for United States federal income tax purposes, a corporation, partnership
or other entity created or organized in or under the laws of the United States, any state of the United States or the District of Columbia,

States of America the timely payment of which is unconditionally guaranteed as a full faith and credit obligation of the United States
of America, which, in either case, are not callable or redeemable at the option of the issuer thereof, and shall also include a depositary
receipt issued by a bank (as defined in Section 3(a)(2) of the Securities Act), as custodian with respect to any such U.S. Government
Obligations or a specific payment of principal of or interest on any such U.S. Government Obligations held by such custodian for the account
of the holder of such depositary receipt; provided that (except as required by law) such custodian is not authorized to make any deduction
from the amount payable to the holder of such depositary receipt from any amount received by the custodian in respect of the U.S. Government
Obligations or the specific payment of principal of or interest on the U.S. Government Obligations evidenced by such depositary receipt.

SECTION 2.4     Interest
Rate Adjustment.

 

(a)            The
interest rate payable on any Series of Notes will be subject to adjustments from time to time if either Moody’s or S&P,
or, in either case, any Substitute Rating Agency downgrades (or subsequently upgrades) the rating assigned to the Notes of such Series,
in the manner described below:

 

(b)            If
the rating from Moody’s (or any Substitute Rating Agency therefor) of the Notes of any Series is decreased to a rating set
forth in the immediately following table, the interest rate on the Notes of such Series will increase such that it will equal the
interest rate payable on the Notes of such Series on the date of their initial issuance, plus the percentage set forth opposite the
ratings from the table below, plus any applicable percentage from the immediately following clause (c) of this Section 2.4.

 

	Moody’s Rating*	 	Percentage	 
	Ba1	 	 	0.250	%
	Ba2	 	 	0.500	%
	Ba3	 	 	0.750	%
	B1 or below	 	 	1.000	%

 

*            Including
the equivalent ratings, in either case of any Substitute Rating Agency or under any successor rating categories of Moody’s.

 

(c)            In
addition, if the rating from S&P (or any Substitute Rating Agency therefor) of the Notes of any Series is decreased to a rating
set forth in the immediately following table, the interest rate on the Notes of such Series will increase such that it will equal
the interest rate payable on the Notes of such Series on the date of their initial issuance, plus the percentage set forth opposite
the ratings from the table below, plus any applicable percentage from the immediately preceding clause (b) of this Section 2.4.

 

	S&P Rating*	 	Percentage	 
	BB+	 	 	0.250	%
	BB	 	 	0.500	%
	BB-	 	 	0.750	%
	B+ or below	 	 	1.000	%

 

*            Including
the equivalent ratings, in either case of any Substitute Rating Agency or under any successor rating categories of S&P.

 

(d)            Notwithstanding
the forgoing, if at any time the interest rate on the Notes of any Series has been adjusted upward and either Moody’s or S&P
(or, in either case, a Substitute Rating Agency therefor), as the case may be, subsequently increases its rating of the Notes of that
Series to any of the threshold ratings set forth above, the interest rate on the Notes of that Series will be decreased such
that the interest rate for the Notes of that Series equals the interest rate payable on the Notes of that Series on the date
of their initial issuance, plus the percentages set forth opposite the ratings from the tables in Section 2.4(b) and (c) above
in effect immediately following the increase in rating. If Moody’s (or any Substitute Rating Agency therefor) subsequently increases
its rating of the Notes of a Series to Baa3 or higher (or its respective equivalent, in either case of any Substitute Rating Agency
or under any successor rating categories of Moody’s) and S&P (or any Substitute Rating Agency therefor) increases its rating
to BBB- or higher (or its respective equivalent, in either case of any Substitute Rating Agency or under any successor rating categories
of S&P), the interest rate on the Notes of that Series will be decreased to the interest rate payable on the Notes of that Series on
the date of their initial issuance.

 

(e)            The
interest rates on the Notes of any Series will permanently cease to be subject to any adjustment described above (notwithstanding
any subsequent downgrade in the ratings by either or both Moody’s or S&P) if the Notes of such Series become rated Baa2
and BBB (or the equivalent of either such rating, in the case of a Substitute Rating Agency) or higher by Moody’s and S&P (or,
in either case, a Substitute Rating Agency therefor), respectively (or one of these ratings if the Notes are only rated by one Rating
Agency). In such case, the interest rate on the Notes of that Series will be the interest rate payable on the Notes of that series
on the date of their initial issuance.

 

    -13- 

     

    

 

(f)            Each
adjustment required by any decrease or increase in a rating set forth above (or an equivalent rating, in either case of any Substitute
Rating Agency or under any successor rating categories of Moody’s or S&P, as the case may be), whether occasioned by the action
of Moody’s or S&P (or, in either case, a Substitute Rating Agency therefor), shall be made independent of any and all other
adjustments; provided, however, in no event shall (1) the interest rate for the Notes of any Series be reduced to below
the interest rate payable on the Notes of that Series on the date of their initial issuance, or (2) the total increase in the
interest rate on the Notes of any Series exceed 2.000% above the interest rate payable on the Notes of that Series on the date
of their initial issuance.

 

(g)            Except
as provided in this Section 2.4(g) and the immediately following Section 2.4(h), no adjustments in the interest rate of
the Notes of a Series shall be made solely as a result of a Rating Agency ceasing to provide a rating of such Series of Notes.
If at any time fewer than two rating agencies provide a rating of the Notes of a Series for any reason beyond the Issuer’s
control, the Issuer will use its commercially reasonable efforts to obtain a rating of such Series of Notes from a Substitute Rating
Agency, to the extent one exists, and if a Substitute Rating Agency exists, for purposes of determining any increase or decrease in the
interest rate on the Notes of a Series pursuant to the tables above:

 

(i)            such
Substitute Rating Agency will be substituted for the last Rating Agency to provide a rating of such Series of such Notes, but which
has since ceased to provide such rating;

 

(ii)            the
relative rating scale used by such Substitute Rating Agency to assign ratings to senior unsecured debt will be determined in good faith
by an independent investment banking institution of national standing appointed by the Issuer and, for purposes of determining the applicable
ratings included in the applicable tables in Section 2.4(b) and (c) above with respect to such Substitute Rating Agency,
such ratings will be deemed to be the equivalent ratings used by Moody’s or S&P, as applicable, in such table; and

 

(iii)            the
interest rate on the Notes of such Series will increase or decrease, as the case may be, such that the interest rate equals the interest
rate payable on the Notes of such Series on the date of their initial issuance, plus the appropriate percentage, if any, set forth
opposite the rating from such Substitute Rating Agency in the applicable table in Section 2.4(b) and (c) above (taking
into account the provisions of clause (i) above) (plus any applicable percentage resulting from a decreased rating by the other rating
agency).

 

(h)            For
so long as only one Rating Agency provides a rating of the Notes of a Series, any subsequent increase or decrease in the interest rate
of such Series of Notes necessitated by a reduction or increase in the rating by the Rating Agency providing the rating shall be
twice the percentage set forth in the applicable table in Section 2.4(b) and (c) above. For so long as none of Moody’s,
S&P or a Substitute Rating Agency provides a rating of the Notes of a Series, the interest rate on the Notes of such Series will
increase to, or remain at, as the case may be, 2.000% above the interest rate payable on the Notes of such Series on the date of
their initial issuance. If Moody’s or S&P either ceases to rate the Notes of a Series for reasons within the Issuer’s
control or ceases to make a rating of the Notes of such Series publicly available for reasons within the Issuer’s control,
the Issuer will not be entitled to obtain a rating from a Substitute Rating Agency and the increase or decrease in the interest rate of
the Notes of such Series shall be determined in the manner described above as if either only one or no Rating Agency provides a rating
of the Notes of such Series.

 

    -14- 

     

    

 

(i)            Any
interest rate increase or decrease described above will take effect from the first day of the interest period, commencing after the
date on which a rating change occurs that requires an adjustment in the interest rate. As such, interest will not accrue at such
increased or decreased rate until the next interest payment date following the date on which the rating change occurs. If
Moody’s, or S&P (or, in either case, a Substitute Rating Agency therefor) changes its rating of the Notes of a
Series more than once during any particular interest period, the last change by such agency will control for purposes of any
interest rate increase or decrease with respect to the Notes of such Series described above relating to such Rating
Agency’s action

 

If the interest rate payable on the Notes of a Series is
increased as described under this Section 2.4, the term “interest,” as used with respect to the Notes of that Series,
will be deemed to include any such additional interest unless the context otherwise requires.

 

The interest rate and the amount of interest payable
on the Notes of any Series will be determined and calculated by the Issuer. For the avoidance of doubt, the Trustee shall have no
duty to monitor any ratings of the Notes, or to determine if an adjustment to any interest rate is to be made or what an interest rate
should be, or make any other determinations or calculations in respect of the interest amounts due on the Notes, or to notify the Holders
of any of the foregoing or determine the consequences thereof.

 

ARTICLE Three

REDEMPTION

 

SECTION 3.1     Selection
of Securities to be Redeemed.

 

(a)            If
less than all of any Series of Notes under the Indenture are to be redeemed at any time, the Trustee will select the Notes for redemption
as follows:

 

(i)            if
the Notes are listed on any national securities exchange, in compliance with the requirements of the principal national securities exchange
on which the Notes are listed; or

 

(ii)            if
the Notes are not listed on any national securities exchange, on a pro rata basis to the extent practicable and when the Notes are in
the form of global securities, in accordance with the applicable rules and procedures of DTC.

 

(b)            In
the event of a partial redemption, the particular Series of Notes to be redeemed will be selected, unless otherwise provided herein,
not less than 10 nor more than 60 days prior to the redemption date by the Trustee from the outstanding Notes of such Series not
previously called for redemption.

 

(c)            The
Trustee will promptly notify the Issuer in writing of the Notes selected for redemption and, in the case of any Note selected for partial
redemption, the principal amount thereof to be redeemed or purchased. No Notes having principal of less than the Minimum Denomination
shall be redeemed in part; except that if all of the Notes of a particular Series of a Holder are to be redeemed, the entire outstanding
amount of such Notes held by such Holder shall be redeemed. Except as provided in the preceding sentence, provisions of the Indenture
that apply to Notes called for redemption also apply to portions of Notes called for redemption.

 

SECTION 3.2     Optional
Redemption.

 

(a)            (A) At
any time, in the case of the 2024 Notes and the 2025 Notes, and (B) prior to (i) in the case of the 2027 Notes, June 15,
2027 (one month before the maturity date of the 2027 Notes), (ii) in the case of the 2029 Notes, May 15, 2029 (two months before
the maturity date of the 2029 Notes) and (iii) in the case of the 2032 Notes, April 15, 2032 (three months before the maturity
of the 2032 Notes) (the applicable date with respect to each of the 2027 Notes, the 2029 Notes and the 2032 Notes, the “Applicable
Par Call Date”), the Issuer may redeem such series of Notes, at its option, in whole or in part, at any time and from time to
time, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

 

(i)            (a) the
sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the redemption date (assuming,
in the case of the 2027 Notes, the 2029 Notes and the 2032 Notes, that the Notes of such series matured on the Applicable Par Call Date)
on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus (1) in the case
of the 2024 Notes, 45 basis points, (2) in the case of the 2025 Notes, 45 basis points, (3) in the case of the 2027 Notes, 50
basis points, (4) in the case of the 2029 Notes, 50 basis points and (5) in the case of the 2032 Notes, 50 basis points, less
(b) interest accrued to the date of redemption, and

 

    -15- 

     

    

 

(ii)            100%
of the principal amount of the Notes of such series to be redeemed,

 

plus,
in either case, accrued and unpaid interest thereon to the applicable redemption date.

 

(b)            With
respect to the 2027 Notes, 2029 Notes and 2032 Notes, on or after the Applicable Par Call Date, the Issuer may redeem any such series
of 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 such
Series of Notes redeemed plus accrued and unpaid interest thereon to the applicable redemption date.

 

The Issuer’s actions and determinations in determining the redemption
price shall be conclusive and binding for all purposes of this Section 3.2, absent manifest error.

 

Notices under the Section 3.2 shall be mailed or electronically
delivered (or otherwise transmitted in accordance with the Depositary’s procedures) at least 10 days but not more than 60 days before
the redemption date to each Holder of 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.

 

Notwithstanding anything in this Section 3.2, the Issuer may acquire
the Notes by means other than a redemption, whether by tender offer, open market purchases, negotiated transactions or otherwise, in accordance
with applicable securities laws, so long as such acquisition does not otherwise violate the terms of the Indenture.

 

Notice of any redemption of the Notes in connection with a transaction
or an event may, at the Issuer’s discretion, be given prior to the completion or the occurrence thereof. Any redemption or notice
may, at the Issuer’s discretion, be subject to one or more conditions precedent, including, but not limited to, completion or occurrence
of a related transaction or event. At the Issuer’s discretion, the redemption date may be delayed until such time as any or all
such conditions shall be satisfied, or such redemption may not occur and such notice may be rescinded in the event that any or all such
conditions shall not have been satisfied by the redemption date, or by the redemption date as so delayed. The Issuer will provide written
notice to the Trustee prior to the close of business two Business Days prior to the redemption date if any such redemption has been rescinded
or delayed. Upon Trustee’s receipt of such notice of the delay of such date of redemption or the rescission of such notice of redemption,
such date of redemption shall be automatically delayed or such notice of redemption shall be automatically rescinded, as applicable, and
the redemption of the Notes shall be automatically delayed or rescinded and cancelled, as applicable, as provided in such notice.

 

SECTION 3.3     Special
Mandatory Redemption.

 

(a)            In
the event that (i) the M&M Acquisition is not consummated on or prior to August 17, 2023, or such later date as the parties
to the Transaction Agreement may agree as the “Outside Date” thereunder, or (ii) the Transaction Agreement is terminated
without the M&M Acquisition being consummated (any such event being a “Special Mandatory Redemption Event”), the
Issuer will redeem (the “Special Mandatory Redemption”) all of the outstanding 2024 Notes, 2025 Notes, 2027 Notes,
2029 Notes and the 2032 Notes at a redemption price equal to 101% of the aggregate principal amount of such Notes, respectively, plus
accrued and unpaid interest, if any, to (but excluding) the redemption date (the “Special Mandatory Redemption Price”).
For purposes of the foregoing, the M&M Acquisition will be deemed consummated if the closing under the Transaction Agreement occurs,
including after giving effect to any amendments to the Transaction Agreement or waivers thereunder acceptable to the Issuer.

 

    -16- 

     

    

 

 

(b)            Notice
of the occurrence of a Special Mandatory Redemption Event and that a Special Mandatory Redemption is to occur (the “Special Mandatory
Redemption Notice”) will be delivered to the Trustee and delivered to Holders of Notes according to the procedures of the Depositary
within 10 Business Days after the Special Mandatory Redemption Event. At the Issuer’s written request, the Trustee shall give the
Special Mandatory Redemption Notice in the name and at the expense of the Issuer. On the redemption date specified in the Special Mandatory
Redemption Notice, which shall be no more than 10 Business Days (or such other minimum period as may be required by the Depositary) after
mailing or sending the Special Mandatory Redemption Notice, the special mandatory redemption shall occur (the date of such redemption,
the “Special Mandatory Redemption Date”). If funds sufficient to pay the Special Mandatory Redemption Price of all
of each Series of the Notes subject to such Special Mandatory Redemption then outstanding on the Special Mandatory Redemption Date
are deposited with a paying agent or the Trustee on or before such Special Mandatory Redemption Date, then on and after such Special Mandatory
Redemption Date, the Notes of such series shall cease to bear interest and, other than the right to receive the Special Mandatory Redemption
Price, all rights under the Notes of such series shall terminate.

 

(c)            Upon
the consummation of the M&M Acquisition, the foregoing clauses (a) and (b) of this Section 3.3 will cease to apply.

 

SECTION 3.4         Redemption
Procedures.

 

Except as provided in this Article Three, the
provisions of Article III of the Base Indenture shall apply in the case of a redemption pursuant to this Article Three.

 

ARTICLE Four

COVENANTS

 

Holders of the Notes shall be entitled to the benefit
of all covenants in Article IV of the Base Indenture and the following additional covenants, which shall be deemed to be provisions
of the Base Indenture with respect to the Notes; provided that this Article Four shall not become a part of the terms of any
other series of Securities:

 

SECTION 4.1           Liens.

 

The Issuer will not, and will not permit any Subsidiary
to, create, incur, issue, assume or guarantee any Indebtedness secured by a Lien (other than Permitted Liens) upon any Principal Property
or Capital Stock of any Subsidiary that directly owns any Principal Property without in any such case making or causing to be made effective
provision whereby the Notes (together with, if the Issuer shall so determine, any other Indebtedness of the Issuer or such Subsidiary
then existing or thereafter created which is not subordinate to the Notes) shall be secured equally and ratably with (or prior to) such
Indebtedness, so long as such Indebtedness shall be so secured, unless after giving effect thereto, the aggregate amount (without duplication)
of all such Indebtedness plus all Attributable Debt of the Issuer and its Subsidiaries in respect of any Sale and Leaseback Transaction
would not exceed 15% of Consolidated Net Tangible Assets.

 

SECTION 4.2           Sale
/ Leaseback Transactions.

 

The Issuer will not, and will not permit any of its
Subsidiaries to, enter into any Sale and Lease-Back Transaction with respect to any Principal Property unless,

 

(a)            the
Issuer or such Subsidiary would be entitled to create, incur, issue, assume or guarantee Indebtedness secured by a Lien pursuant to Section 4.1
on the Principal Property to be leased in an amount equal to the Attributable Debt with respect to such Sale and Leaseback Transaction
without equally and ratably securing the Notes;

 

(b)            the
Issuer or such Subsidiary shall apply, within 180 days of the effective date of any such arrangement, an amount not less than the greater
of (i) the net proceeds of the sale of such Principal Property or (ii) the fair market value (as determined by the Board of
Directors) of such Principal Property to either the prepayment or retirement (other than any mandatory prepayment or retirement) of Indebtedness
incurred or assumed by the Issuer or such Subsidiary (other than Indebtedness owned by Issuer or any of its Subsidiaries) which by its
terms matures at or is extendible or renewable at the option of the obligor to a date more than twelve months after the date of the creation
of such Indebtedness, or to the acquisition, construction or improvement of a manufacturing plant or manufacturing facility; or

 

    -17-

     

    

 

(c)            the
Attributable Debt of the Issuer or such Subsidiary in respect of such Sale and Lease-Back Transaction and all other Sale and Lease-Back
Transactions entered into after the Issue Date (other than any such Sale and Lease-Back Transaction as would be permitted as described
in clauses (a) and (b) of this covenant, plus the aggregate principal amount of Indebtedness secured by Liens then outstanding
(not including any such Indebtedness secured by Permitted Liens) which do not equally and ratably secure the Notes (or secure the Notes
on a basis that is prior to other Indebtedness secured thereby) would not exceed 15% of Consolidated Net Tangible Assets.

 

SECTION 4.3           Additional
Guarantees.

 

After the Issue Date, the Issuer shall cause each
Subsidiary that guarantees any Indebtedness of the Issuer or any of the Guarantors under the Credit Agreements, in each case, substantially
at the same time, to execute and deliver to the Trustee a Guarantee pursuant to which such Subsidiary will unconditionally Guarantee,
on a joint and several basis, the full and prompt payment of the principal of, premium, interest and additional amounts, if any, on the
Notes and all other obligations under the Indenture on the same terms and conditions as those set forth in the Indenture.

 

SECTION 4.4           Reports.

 

Whether or not required by the Commission, so long
as any Notes are outstanding, the Issuer shall electronically file with the Commission by the respective dates specified in the Commission’s
rules and regulations (the “Required Filing Date”), unless, in any such case, such filings are not then permitted
by the Commission:

 

(a)            all
quarterly and annual financial information that would be required to be contained in a filing with the Commission on Forms 10-Q and
10-K if the Issuer were required to file such Forms, including a “Management’s Discussion and Analysis of Financial Condition
and Results of Operations” and, with respect to the annual information only, a report on the annual financial statements by the
Issuer’s certified independent accountants; and

 

(b)            all
current reports that would be required to be filed with the Commission on Form 8-K if the Issuer were required to file such reports;

 

If such filings with the Commission are not then
permitted by the Commission, or such filings are not generally available on the Internet free of charge, the Issuer shall, within 15 days
of each Required Filing Date, transmit by mail to Holders of the Notes, as their names and addresses appear in the Note register, without
cost to such Holders of the Notes, and file with the Trustee copies of the information or reports that the Issuer would be required to
file with the Commission pursuant to the first paragraph of this Section 4.4 if such filing were then permitted.

 

So long as the Parent Guarantor complies with the
requirements of Rules 3-10 and 13-01 of Regulation S-X promulgated by the Commission (or any successor provision), the reports,
information and other documents required to be filed and furnished to Holders of the Notes pursuant to this Section 4.4 may, at the
option of the Issuer, be filed by and be those of the Parent Guarantor rather than the Issuer.

 

The availability of the foregoing reports on the
Commission’s EDGAR service (or successor thereto) shall be deemed to satisfy the Issuer’s delivery obligations to the Trustee
and Holders.

 

    -18-

     

    

 

Delivery of such reports, information and documents
to the Trustee is for informational purposes only, and the Trustee’s receipt of such shall not constitute actual or constructive
knowledge or notice of any information contained therein or determinable from information contained therein, including the Issuer’s
compliance with any of its covenants hereunder (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates).
The Trustee shall have no duty to monitor or confirm, on a continuing basis or otherwise, the Issuer’s or any other person’s
compliance with any of the covenants under the Indenture, to determine whether the Issuer posts reports, information or documents on the
SEC’s website (including via the EDGAR filing system), the Issuer’s (or Parent Guarantor’s) website or otherwise, to
collect any such information from the SEC’s website (including via the EDGAR filing system), the Issuer’s (or Parent Guarantor’s)
website or otherwise, or to review or analyze reports delivered to it to ensure compliance with the provisions of the Indenture, to ascertain
the correctness or otherwise of the information or the statements contained therein or to participate in any conference calls.

 

SECTION 4.5           Change
of Control Event.

 

(a)            If
a Change of Control Event occurs, each Holder will have the right to require the Issuer to repurchase all or any part (equal to $2,000
or an integral multiple of $1,000 in excess thereof) of that Holder’s Notes pursuant to a Change of Control Offer on the terms set
forth in the Indenture. In the Change of Control Offer, the Issuer shall offer to purchase such Notes at a purchase price in cash (the
“Change of Control Payment”) equal to 101% of the aggregate principal amount of Notes repurchased plus accrued and
unpaid interest on the Notes repurchased, to the date of purchase (subject to the right of Holders of record on the relevant record date
to receive interest due on the relevant interest payment date).

 

(b)            Within
30 days following any Change of Control Event, the Issuer will send a notice to each Holder describing the transaction or transactions
that constitute the Change of Control and offering (the “Change of Control Offer”) to repurchase Notes on the date
specified in the notice (the “Change of Control Payment Date”), which date will be no earlier than 30 days and
no later than 60 days from the date such notice is sent, pursuant to the procedures required by the Indenture and described in such
notice. Such notice shall state:

 

(i)            that
a Change of Control Event has occurred and that such Holder has the right to require the Issuer to purchase all or a portion of such Holder’s
Notes at a purchase price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest to the date of purchase
(subject to the right of the Holders of record on the relevant record date to receive interest on the relevant interest payment date);

 

(ii)            the
circumstances and relevant facts and financial information regarding such Change of Control Event;

 

(iii)            the
Change of Control Payment Date; and

 

(iv)            the
instructions determined by the Issuer, consistent with this Section 4.5, that a Holder must follow in order to have its Notes purchased.

 

(c)            Holders
electing to have a Note purchased shall be required to surrender the Note, with an appropriate form duly completed, to the Issuer at the
address specified in the notice at least three Business Days prior to the Change of Control Purchase Date. The Holders shall be entitled
to withdraw their election if the Trustee or the Issuer receives not later than one Business Day prior to the Change of Control Purchase
Date a facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Note which was delivered for
purchase by the Holder and a statement that such Holder is withdrawing his election to have such Note purchased. Holders whose Notes are
purchased only in part shall be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered.

 

(d)            On
the Change of Control Payment Date, the Issuer will, 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

 

    -19-

     

    

 

(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 Issuer.

 

(e)            On
the Change of Control Purchase Date all Notes purchased by the Issuer under this Section 4.5 shall be delivered to the Trustee for
cancellation, and the Issuer shall pay the Change of Control Payment to the Holders entitled thereto.

 

(f)            The
Paying Agent will promptly mail or provide in accordance with the applicable procedures of the DTC to each Holder of Notes properly tendered
the Change of Control Payment for such Notes, and the Trustee will promptly authenticate and mail (or cause to be transferred by book
entry) to each 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.

 

(g)            The
Issuer shall not be required to make a Change of Control Offer upon a Change of Control Event if (i) a third party makes the Change
of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Section 4.5 applicable
to a Change of Control Offer made by the Issuer and purchases all Notes properly tendered and not withdrawn under the Change of Control
Offer or (ii) notice of redemption has been given pursuant to the Indenture as described above Section 3.2, unless and until
there is a default in the payment of the applicable redemption price. Notwithstanding anything to the contrary contained herein, a Change
of Control Offer may be made in advance of a Change of Control Event or conditional upon the occurrence of a Change of Control Event,
if a definitive agreement is in place for the Change of Control at the time the Change of Control Offer is made and such Change of Control
Offer is otherwise made in compliance with the provisions of this Section 4.5.

 

(h)            The
Issuer shall comply with the requirements of Section 14e−1 of the Exchange Act and any other securities laws or regulations
in connection with the repurchase of Notes pursuant to this Section 4.5 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 provisions of this Section 4.5, the Issuer shall comply with the applicable securities laws and regulations
and shall not be deemed to have breached its obligations under this Section 4.5 by virtue thereof.

 

ARTICLE Five

merge with an Affiliate incorporated solely for the purpose of reincorporating the Issuer in a (or another) state of the United States,

Merger and Sale of Assets by a Guarantor.

 

(a)            Subject
to the provisions described under Section 6.4(a), no Guarantor shall consolidate or merge with or into or wind up into (whether or

ARTICLE Six

GUARANTEE OF NOTES

 

SECTION 6.1           Guarantee.

 

Subject to the provisions of this
Article Six, each Guarantor, by execution of this Twelfth Supplemental Indenture, jointly and severally, unconditionally
guarantees to each Holder (a) the due and punctual payment of the principal of, premium, if any, and interest on each Note,
when and as the same shall become due and payable, whether at maturity, by acceleration or otherwise, the due and punctual payment
of interest on the overdue principal of, premium, if any, and, to the extent permitted by law, interest on the Notes, to the extent
lawful, and the due and punctual payment of all other Obligations and due and punctual performance of all obligations of the Issuer
to the Holders or the Trustee all in accordance with the terms of such Note and the Indenture, and (b) in the case of any
extension of time of payment or renewal of any Notes or any of such other Obligations, that the same will be promptly paid in full
when due or performed in accordance with the terms of the extension or renewal, at stated maturity, by acceleration or otherwise.
Each Guarantor, by execution of this Twelfth Supplemental Indenture, agrees that its obligations hereunder shall be absolute and
unconditional, irrespective of, and shall be unaffected by, any invalidity, irregularity or unenforceability of any such Note or the
Indenture, any failure to enforce the provisions of any such Note or the Indenture, any waiver, modification or indulgence granted
to the Issuer with respect thereto by the Holder of such Note, or any other circumstances which may otherwise constitute a legal or
equitable discharge of a surety or such Guarantor.

 

Each Guarantor hereby waives diligence, presentment,
demand for payment, filing of claims with a court in the event of insolvency or bankruptcy of the Issuer, any right to require a proceeding
first against the Issuer, protest or notice with respect to any such Note or the Indebtedness evidenced thereby and all demands whatsoever,
and covenants that this Guarantee will not be discharged as to any such Note except by payment in full of the principal thereof, and interest
thereon. Each Guarantor hereby agrees that, as between such Guarantor, on the one hand, and the Holders and the Trustee, on the other
hand, (a) subject to this Article Six, the maturity of the Obligations guaranteed hereby may be accelerated as provided in Article Seven
for the purposes of this Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect
of the Obligations guaranteed hereby, and (b) in the event of any declaration of acceleration of such Obligations as provided in
Article Seven, such Obligations (whether or not due and payable) shall forthwith become due and payable by each Guarantor for the
purpose of this Guarantee.

 

SECTION 6.2           Execution
and Delivery of Notation of Guarantee.

 

To further evidence the Guarantee set forth in Section 6.1,
each Guarantor hereby agrees that a notation of such Guarantee, substantially in the form included in Exhibit B hereto, shall
be endorsed on each Note authenticated and delivered by the Trustee and such Guarantee shall be executed by either manual or facsimile
signature of an Officer or an Officer of a general partner, as the case may be, of each Guarantor. The validity and enforceability of
any Guarantee shall not be affected by the fact that it is not affixed to any particular Note.

 

Each Guarantor hereby agrees that its Guarantee set
forth in Section 6.1 shall remain in full force and effect notwithstanding any failure to endorse on each Note a notation of such
Guarantee.

 

If an Officer of a Guarantor whose signature is on
the Indenture or a Guarantee no longer holds that office at the time the Trustee authenticates the Note on which such Guarantee is endorsed
or at any time thereafter, such Guarantor’s Guarantee of such Note shall be valid nevertheless.

 

The delivery of any Note by the Trustee, after the
authentication thereof hereunder, shall constitute due delivery of any Guarantee set forth in the Indenture on behalf of each Guarantor.

SECTION 6.3           Limitation
of Guarantee.

 

Each Guarantor, and by its acceptance of the Notes,
each Holder, hereby confirms that it is the intention of all such parties that the Guarantee of such Guarantor not constitute a fraudulent
transfer or conveyance for purposes of any Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act
or any similar federal or state law to the extent applicable to any Guarantee. To effectuate the foregoing intention, the Trustee, the
Holders and the Guarantors hereby irrevocably agree that the obligations of each Guarantor are limited to the maximum amount as will,
after giving effect to all other contingent and fixed liabilities of such Guarantor and after giving effect to any collections from or
payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under its Guarantee or pursuant
to its contribution obligations under the Indenture, result in the obligations of such Guarantor under its Guarantee not constituting
a fraudulent conveyance or fraudulent transfer under federal or state law. Each Guarantor that makes a payment or distribution under a
Guarantee shall be entitled to a contribution from each other Guarantor in a pro rata amount based on the assets of each Guarantor.

 

SECTION 6.4           Release
of Guarantor.

 

(a)            A
Guarantor (other than a company that is a direct or indirect Parent of the Issuer except in the case of clause (i)(2) or (4) below)
shall be automatically and unconditionally released and discharged from all of its obligations under its Guarantee if:

 

(i)            (1) 
all of its assets or Capital Stock is sold or transferred,

 

(2)            the
Guarantor merges with or into, or consolidates with or amalgamates with, or transfers all or substantially all of its assets to, another
Person in compliance with Article Five,

 

(3)            such
Guarantor ceases to be a Subsidiary of the Issuer in connection with any (direct or indirect) sale of Capital Stock or other transaction,
or

 

(4)            the
Notes are subject to legal defeasance or the Indenture is satisfied and discharged as provided under Article VIII of the Base Indenture;
or

 

(5)            such
Guarantor is released from its guarantee of the Credit Agreements; and

 

(ii)            such
Guarantor ceases to, or substantially contemporaneously with the release of such Guarantor’s obligation under its Guarantee hereunder
will cease to, or at such time does not, guarantee the Issuer’s obligations under the Credit Agreements; and

 

(iii)            such
Guarantor has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent
herein provided for relating to such transaction have been complied with; and

 

(b)            The
Trustee shall execute any documents reasonably requested by the Issuer or a Guarantor in order to evidence the release of such Guarantor
from its obligations under its Guarantee endorsed on the Notes and under this Article Six upon receipt of an Officer’s Certificate
and an Opinion of Counsel to the effect that such release is permitted by the Indenture.

 

SECTION 6.5           Waiver
of Subrogation.

 

Each Guarantor hereby irrevocably waives any claim
or other rights which it may now or hereafter acquire against the Issuer that arise from the existence, payment, performance or enforcement
of such Guarantor’s obligations under its Guarantee and the Indenture, including, without limitation, any right of subrogation,
reimbursement, exoneration, indemnification, and any right to participate in any claim or remedy of any Holder of Notes against the Issuer,
whether or not such claim, remedy or right arises in equity, or under contract, statute or common law, including, without limitation,
the right to take or receive from the Issuer, directly or indirectly, in cash or other property or by set-off or in any other manner,
payment or security on account of such claim or other rights. If any amount shall be paid to any Guarantor in violation of the preceding
sentence and the Notes shall not have been paid in full, such amount shall have been deemed to have been paid to such Guarantor for the
benefit of, and held in trust for the benefit of, the Holders, and shall forthwith be paid to the Trustee for the benefit of such Holders
to be credited and applied upon the Notes, whether matured or unmatured, in accordance with the terms of the Indenture. Each Guarantor
acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated by the Indenture and that
the waiver set forth in this Section 6.5 is knowingly made in contemplation of such benefits.

SECTION 7.1           Events
of Default.

 

(a)            With
respect to the Notes, Section 6.1 of the Base Indenture shall be replaced in its entirety with the following, which shall be deemed
to be provisions of the Base Indenture with respect to the Notes; provided that the terms of this Article Seven shall not
become a part of the terms of any other series of Securities:

 

An “Event of Default” occurs if:

 

(a)  the Issuer defaults in payment
when due and payable, upon redemption (including a Special Mandatory Redemption), acceleration or otherwise, of principal of, or premium,
if any, on the Notes;

 

(b)            the
Issuer defaults in the payment when due of interest on or with respect to the Notes and such default continues for a period of 30 days;

 

(c)            the
Issuer defaults in the performance of, or breaches any covenant, warranty or other agreement contained in the Indenture (other than a
default in the performance or breach of a covenant, warranty or agreement which is specifically dealt with in clauses (a) or
(b) above) and such default or breach continues for a period of 60 days after the notice specified below;

 

(d)            a
default under any mortgage, indenture or instrument under which there is issued or by which there is secured or evidenced any Indebtedness
for money borrowed by the Issuer or any Subsidiary Guarantor (other than Indebtedness under a Qualified Securitization Financing) or the
payment of which is guaranteed by the Issuer or any Subsidiary Guarantor (other than Indebtedness under a Qualified Securitization Financing)
(other than Indebtedness owed to the Issuer or a Subsidiary), whether such Indebtedness or guarantee now exists or is created after the
Issue Date, if (i) such default either (1) results from the failure to pay any such Indebtedness at its stated final maturity
(after giving effect to any applicable grace periods) or (2) relates to an obligation other than the obligation to pay principal
of any such Indebtedness at its stated final maturity and results in the holder or holders of such Indebtedness causing such Indebtedness
to become due prior to its stated maturity and (ii) the principal amount of such Indebtedness, together with the principal amount
of any other such Indebtedness in default for failure to pay principal at stated final maturity (after giving effect to any applicable
grace periods), or the maturity of which has been so accelerated, aggregate $100.0 million or more at any one time outstanding; or

 

(e)            the
Issuer or any Guarantor that is a Significant Subsidiary pursuant to or within the meaning of any Bankruptcy Law:

 

(i)            commences

to the appointment of a Custodian of it or for any substantial part of its property; or

 

(iv)            makes
a general assignment for the benefit of its creditors or takes any comparable action under any foreign laws relating to insolvency;

 

    -24-

     

    

 

(f)            a
court of competent jurisdiction enters an order or decree under any Bankruptcy Law that:

 

(i)            is
for relief against the Issuer or any Significant Subsidiary in an involuntary case;

 

(ii)            appoints
a Custodian of the Issuer or any Significant Subsidiary or for any substantial part of its property;

 

(iii)            orders
the winding up or liquidation of the Issuer or any Significant Subsidiary; or

 

(iv)            or
any similar relief is granted under any foreign laws and the order or decree remains unstayed and in effect for 60 days; or

 

(g)            any
Guarantee of a Significant Subsidiary fails to be in full force and effect (except as contemplated by the terms thereof) or any Guarantor
(other than the Parent Guarantor) denies or disaffirms its obligations under its Guarantee and such Default continues for 10 days.

 

The foregoing shall constitute Events of Default
whatever the reason for any such Event of Default and whether it is voluntary or involuntary or is effected by operation of law or pursuant
to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body.

 

The term “Bankruptcy Law” means
Title 11, United States Code, or any similar Federal, state or, so long as the Issuer is domiciled in Luxembourg, Luxembourg law, in each
case for the relief of debtors. The term “Custodian” means any receiver, trustee, assignee, liquidator, custodian or
similar official under any Bankruptcy Law.

 

(b)  Within 30 days after the Issuer
has actual knowledge of any Default or Event of Default, the Issuer is required to deliver to the Trustee an Officers’ Certificate
specifying the Default or Event of Default, its status and what action the Issuer is taking or proposes to take in respect thereof.

 

(c)  With respect to the Notes, Section 6.2
of the Base Indenture shall be amended such that all references to “Section 6.1(d) or (e)” are references to “Section 6.1(f) or
(g)”, which references shall be deemed to be provisions of the Base Indenture with respect to the Notes; provided that the terms
of this Article Seven shall not become a part of the terms of any other series of Securities:

 

(d)  In the event of any Event of
Default specified in Section 6.1(d) of the Base Indenture, such Event of Default and all consequences thereof (excluding, however,
any resulting payment default) shall be annulled, waived and rescinded, automatically and without any action by the Trustee or the Holders
of the Notes, if within 20 days after such Event of Default arose the Issuer delivers an Officer’s Certificate to the Trustee stating
that (i) the Indebtedness or guarantee that is the basis for such Event of Default has been discharged or (ii) the Holders thereof
have rescinded or waived the acceleration, notice or action (as the case may be) giving rise to such Event of Default or (iii) the
default that is the basis for such Event of Default has been cured, it being understood that in no event shall an acceleration of the
principal amount of the Notes pursuant to Section 6.2 of the Base Indenture be annulled, waived or rescinded upon the happening of
any such events.

 

ARTICLE Eight

SATISFACTION AND DISCHARGE

 

With respect to the Notes, Article VIII of the
Base Indenture shall be superseded in its entirety by the following language with respect to, and solely for the benefit of the Holders
of the Notes; provided that this Article Eight shall not become part of the terms of any other series of Securities:

 

    -25-

     

    

 

SECTION 8.1           Discharge
of Liability on Notes.

 

The Indenture shall be discharged and shall cease
to be of further effect (except as to surviving rights of registration of transfer or exchange of Notes and the surviving rights of the
Trustee, as expressly provided for in the Indenture) as to all outstanding Notes:

 

(a)            when
either:

 

(i)            all
the Notes theretofore authenticated and delivered (other than Notes which have been replaced pursuant to Section 2.8 of the Base
Indenture or paid and Notes for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Issuer
and thereafter repaid to the Issuer or discharged from such trust) have been delivered to the Trustee for cancellation; or

 

(ii)            all
of the Notes (A) have become due and payable, (B) will become due and payable at their stated maturity within one year or (C) if
redeemable at the option of the Issuer, are to be called for redemption within one year under arrangements satisfactory to the Trustee
for the giving of notice of redemption by the Trustee in the name, and at the expense, of the Issuer, and the Issuer has irrevocably deposited
or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders, cash in U.S. Dollars, U.S. Government
Obligations or a combination thereof in amounts as will be sufficient without consideration of any reinvestment of interest, in the opinion
of a nationally recognized firm of independent public accountants (in the event that U.S. Government Obligations are deposited), to pay
and discharge the entire Indebtedness on the Notes not delivered to the Trustee for cancellation for principal, premium, if any, and accrued
interest to the date of maturity or redemption;

 

(b)            the
Issuer and/or the Guarantors has paid or caused to be paid all sums payable by them under the Indenture;

 

(c)            the
Issuer has delivered irrevocable instructions to the Trustee to apply the deposited money toward the payment of the Notes at maturity
or the redemption date, as the case may be; and

 

(d)            the
Issuer has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel stating that all conditions precedent under
the Indenture relating to the satisfaction and discharge of the Indenture have been complied with.

 

SECTION 8.2           Defeasance.

 

(a)            The
Issuer may, at its option and at any time, elect to have all of its obligations discharged with respect to the outstanding Notes issued
under the Indenture (“Legal Defeasance”) except for:

 

(i)            the
rights of Holders of outstanding Notes issued thereunder to receive payments in respect of the principal of, or interest or premium, if
any, on such Notes when such payments are due from the trust referred to below;

 

(ii)            the
Issuer’s obligations with respect to the Notes issued thereunder concerning issuing temporary Notes, registration of Notes, mutilated,
destroyed, lost or stolen Notes and the maintenance of an office or agency for payment and money for security payments held in trust;

 

(iii)            the
rights, powers, trusts, duties and immunities of the Trustee, and the Issuer’s obligations in connection therewith; and

 

(iv)            this
Section 8.2(a).

 

    -26-

     

    

 

(b)          The
Issuer may, at its option and at any time, elect to have its obligations released with respect to Sections 4.1, 4.2, 4.3 and 4.4 of this
Twelfth Supplemental Indenture and the operation of Article Five of this Twelfth Supplemental Indenture (“Covenant Defeasance”)
and thereafter any omission to comply with those covenants will not constitute a Default or Event of Default with respect to the Notes.
The Issuer may exercise its Legal Defeasance option notwithstanding its prior exercise of its Covenant Defeasance option.

 

If the Issuer exercises its Legal Defeasance option,
payment of the Notes so defeased may not be accelerated because of an Event of Default. If the Issuer exercises its Covenant Defeasance
option, payment of the Notes so defeased may not be accelerated because of an Event of Default specified in Sections 6.1(c), 6.1(d), 6.1(e),
6.1(f) (with respect to Significant Subsidiaries of the Issuer only), 6.1(g) (with respect to Significant Subsidiaries of the
Issuer only) and 6.1(h) of the Base Indenture or because of the failure of the Issuer to comply with Section 5.1.

 

Upon satisfaction of the conditions set forth herein
and upon request of the Issuer, the Trustee shall acknowledge in writing the discharge of those obligations that the Issuer terminates.

 

(c)          Notwithstanding
clauses (a) and (b) above, the Issuer’s obligations in Sections 2.4, 2.5, 2.6, 2.7, 2.8, 2.9, 7.6 and 7.7 of the Base
Indenture and in this Article shall survive until the Notes have been paid in full. Thereafter, the Issuer’s obligations in
Sections 8.6 and 8.7 of this Twelfth Supplemental Indenture shall survive such satisfaction and discharge.

 

SECTION 8.3           Conditions
to Defeasance.

 

(a)            The
Issuer may exercise its Legal Defeasance option or its Covenant Defeasance option only if:

 

(i)            the
Issuer has irrevocably deposited with the Trustee, in trust, for the benefit of the Holders, cash in U.S. Dollars, U.S. Government Obligations
or a combination thereof in amounts as will be sufficient without consideration of investment of interest, in the opinion of a nationally
recognized firm of independent public accountants (in the event that U.S. Government Obligations are deposited), to pay the principal
of, or premium and interest, if any, on the outstanding Notes issued thereunder on the stated maturity or on the applicable redemption
date, as the case may be, and the Issuer must specify whether the Notes are being defeased to maturity or to a particular redemption date;

 

(ii)            in
the case of Legal Defeasance, the Issuer has delivered to the Trustee an Opinion of Counsel confirming that (1) the Issuer has received
from, or there has been published by, the Internal Revenue Service a ruling or (2) since the Issue Date, there has been a change
in the applicable federal income tax law, in either case to the effect that, and based thereon such Opinion of Counsel will confirm that,
the beneficial owners of the respective outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a
result of such Legal Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times
as would have been the case if such Legal Defeasance had not occurred;

 

(iii)            in
the case of Covenant Defeasance, the Issuer has delivered to the Trustee an Opinion of Counsel confirming that the beneficial owners of
the respective outstanding Notes will not recognize income, gain or loss for federal income tax purposes as a result of such Covenant
Defeasance and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been
the case if such Covenant Defeasance had not occurred;

 

(iv)            no
Default or Event of Default has occurred and is continuing on the date of such deposit (other than a Default or Event of Default resulting
from the borrowing of funds to be applied to such deposit and the granting of Liens in connection therewith);

 

(v)            such
Legal Defeasance or Covenant Defeasance will not result in a breach or violation of, or constitute a default under any material agreement
or instrument (other than the Indenture) to which the Issuer or any of its Subsidiaries is a party or by which the Issuer or any of its
Subsidiaries is bound;

 

    -27-

     

    

 

(vi)            the
Issuer must deliver to the Trustee an Officer’s Certificate stating that the deposit was not made by the Issuer with the intent
of preferring the Holders of Notes over the other creditors of the Issuer with the intent of defeating, hindering, delaying or defrauding
creditors of the Issuer or others; and

 

(vii)            the
Issuer must deliver to the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent
relating to the Legal Defeasance or the Covenant Defeasance as contemplated by this Article Eight have been complied with.

 

(b)            Before
or after a deposit, the Issuer may make arrangements satisfactory to the Trustee for the redemption of such Notes at a future date in
accordance with Article III.

 

SECTION 8.4           Application
of Trust Money.

 

The Trustee shall hold in trust money or U.S. Government
Obligations (including proceeds thereof) deposited with it pursuant to this Article Eight. It shall apply the deposited money and
the money from U.S. Government Obligations through each Paying Agent and in accordance with the Indenture to the payment of principal
of and interest on the Notes so discharged or defeased.

 

SECTION 8.5           Repayment
to Issuer.

 

Each of the Trustee and each Paying Agent shall promptly
turn over to the Issuer upon request any money or U.S. Government Obligations held by it as provided in this Article Eight which,
in the written opinion of nationally recognized firm of independent public accountants delivered to the Trustee (which delivery shall
only be required if U.S. Government Obligations have been so deposited), are in excess of the amount thereof which would then be required
to be deposited to effect an equivalent discharge or defeasance in accordance with this Article Eight.

 

Subject to any applicable abandoned property law,
the Trustee and each Paying Agent shall pay to the Issuer upon written request any money held by them for the payment of principal or
interest that remains unclaimed for two years, and, thereafter, Holders entitled to the money must look to the Issuer for payment as general
creditors, and the Trustee and each Paying Agent shall have no further liability with respect to such monies.

 

SECTION 8.6           Indemnity
for U.S. Government Obligations.

 

The Issuer shall pay and shall indemnify the Trustee
against any tax, fee or other charge imposed on or assessed against deposited U.S. Government Obligations or the principal and interest
received on such U.S. Government Obligations.

 

SECTION 8.7           Reinstatement.

 

If the Trustee or any Paying Agent is unable to apply
any money or U.S. Government Obligations in accordance with this Article Eight by reason of any legal proceeding or by reason of
any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, the Issuer’s
obligations under the Indenture and the Notes so discharged or defeased shall be revived and reinstated as though no deposit had occurred
pursuant to this Article Eight until such time as the Trustee or any Paying Agent is permitted to apply all such money or U.S. Government
Obligations in accordance with this Article Eight; provided, however, that, if the Issuer has made any payment of principal
of or interest on, any such Notes because of the reinstatement of its obligations, the Issuer shall be subrogated to the rights of the
Holders of such Notes to receive such payment from the money or U.S. Government Obligations held by the Trustee or any Paying Agent.

approves the substance thereof.

 

After an amendment under this Section 9.3 becomes
effective, the Issuer shall mail (or deliver pursuant to the procedures of the DTC) to the Holders a notice briefly describing such amendment.
The failure to give such notice to all Holders, or any defect therein, shall not impair or affect the validity of an amendment under this
Section 9.3.

 

SECTION 9.4           Payment
for Consent.

 

(a)            The
Issuer will not, and will not permit any of its Subsidiaries to, directly or indirectly, pay or cause to be paid any consideration to
or for the benefit of any Holder of Notes for or as an inducement to any consent, waiver or amendment of any of the terms or provisions
of the Indenture or the Notes unless such consideration is offered to be paid and is paid to all Holders of the Notes that consent, waive
or agree to amend in the time frame set forth in the solicitation documents relating to such consent, waiver or agreement.

registered address of each Holder thereof.

 

3.            Paying
Agent and Registrar

 

Initially, U.S. Bank Trust Company, National Association

4.            Indenture

 

The Issuer issued the 2024 Notes under an Indenture,

The aggregate principal amount at maturity of the
2024 Notes which may be authenticated and delivered under the Indenture shall be unlimited. In addition, the aggregate principal amount

such monies.

11.            Discharge

the Indenture or the 2024 Notes to, among other things, cure any ambiguity, defect or inconsistency.

 

13.            Defaults
and Remedies

 

If an Event of Default occurs (other than an Event

of, premium, if any, and interest on all the 2024 Notes shall become immediately due and payable without any declaration or other act
on the part of the Trustee or any Holders. Under certain circumstances, the Holders of a majority in principal amount of the outstanding
2024 Notes may rescind any such acceleration with respect to the 2024 Notes and its consequences.

 

14.            Trustee
Dealings with the Issuer

 

Subject to certain limitations imposed by the TIA,
the Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of 2024 Notes and may otherwise
deal with and collect obligations owed to it by the Issuer or its Affiliates and, subject to the Indenture, may otherwise deal with the
Issuer or its Affiliates with the same rights it would have if it were not Trustee.

holder of any equity interests in the Issuer or any Guarantor shall have any liability for or any obligations, covenants or agreements
of the Issuer or the Guarantors under the 2024 Notes or the Indenture or for any claim based thereon or otherwise in respect of, or by
reason of, such obligations or their creation. By accepting a 2024 Note, each holder expressly waives and releases all such liability.

CELANESE US HOLDINGS LLC, a Delaware limited liability
company (the “Issuer”), promises to pay interest on the principal amount of this 2032 Note at the rate per annum shown

on January 15 and July 15 of each year, commencing January 15, 2023, and on the final maturity date of the 2032 Notes.
Interest on the 2032 Notes shall accrue from the most recent date to which interest has been paid or duly provided for or, if no interest
has been paid or duly provided for, from July 14, 2022 until the principal hereof is due. Interest shall be computed on the basis
of a 360 day year comprised of twelve 30-day months. The Issuer shall pay interest on overdue principal and premium, if any, at the rate
borne by the 2032 Notes, and it shall pay interest on overdue installments of interest at the same rate to the extent lawful.

of Payment

 

The Issuer shall pay interest on the 2032 Notes

(whether or not a Business Day). Holders must surrender 2032 Notes to a Paying Agent to collect principal payments. The Issuer shall
pay principal, premium, if any, and interest in money of the United States of America, that at the time of payment is legal tender for

if any, and interest) shall be made by wire transfer of immediately available funds to the accounts specified by The Depository Trust
Company, the Issuer or any successor depositary. The Issuer will make all payments in respect of a certificated 2032 Note (including

of the Issuer, payment of interest may be made by mailing a check to the registered address of each Holder thereof.

Agent and Registrar

 

Initially, U.S. Bank Trust Company, National Association
