Agent (the “Authenticating Agent”) for the Notes pursuant to Section 2.3 of the Base Indenture. Neither the Trustee
nor any agent of the Trustee shall be responsible for any action taken or not taken by the Authenticating Agent. The Authenticating Agent
shall have all of the rights, privileges, protections and immunities granted to the Trustee in the Indenture mutatis mutandis.

 

(l)            The
Notes (and the notation of Guarantee endorsed thereon) will be issuable in the form of one or more Global Securities and the Common Depositary
for such Global Securities will be Elavon Financial Services DAC or another Person designated as Common Depositary for Euroclear and Clearstream
or another Person designated as Common Depositary by the Issuer. Neither the Trustee nor any agent of the Trustee shall be responsible
for any action taken or not taken by the Common Depositary.

 

(m)            Subject
to clause (n) below, the Issuer shall pay principal of, premium, interest and additional amounts, if any, on the Notes in money of
the member states of the European Union that have adopted or that adopt the single currency in accordance with the treaty establishing
the European Community, as amended by the Treaty on European Union, that at the time of payment is legal tender for payment of public
and private debts.

 

(n)            Principal
of, premium, interest and additional amounts, if any, on the Notes will be payable at the office or agency of the Paying Agent at 125
Old Broad Street, Fifth Floor, London EC2N 1AR, until such time as the Issuer designates an alternate place of payment. If on or after
the date of this Thirteenth Supplemental Indenture, the Euro is unavailable to the Issuer due to the imposition of exchange controls or
other circumstances beyond the Issuer’s control or if the Euro is no longer being used by the then member states of the European
Union that have adopted the Euro as their currency or for the settlement of transactions by public institutions of or within the international
banking community, then all payments in respect of the Notes will be made in Dollars until the Euro is again available to the Issuer or
so used. The amount payable on any date in Euros will be converted into Dollars on the basis of the most recently available market exchange
rate for Euro. Any payment in respect of the Notes so made in Dollars will not constitute an Event of Default under the Notes or this
Thirteenth Supplemental Indenture. Neither the Trustee nor the Paying Agent shall have any responsibility for any calculation or conversion
in connection with the foregoing.

 

    	 	-14-	 

     

    

 

(o)            The
Issuer shall, on or before each due date of the principal of, premium, interest and additional amounts, if any, the Notes, deposit with
the Paying Agent a sum (in funds which are immediately available on the due date for such payment) sufficient to pay such principal, premium,
interest or additional amounts, if any, and (unless such Paying Agent is the Trustee) the Issuer will promptly notify the Trustee in writing
of any failure to take such action; provided that if such deposit is made on the due date, such deposit shall be received by the Paying
Agent by 10:00 a.m. London time, on such date.

 

(p)            A
Holder may transfer or exchange Notes only in accordance with the Indenture. Upon any transfer or exchange, the Registrar, the Transfer
Agent and the Trustee may require a Holder, among other things, to furnish appropriate endorsements or transfer documents. No service
charge shall be made for any registration of transfer or exchange, but the Issuer or the Trustee may require the payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection therewith. The Issuer is not required to transfer or exchange
any Note for a period of 15 days before a selection of Notes to be redeemed or purchased.

 

(q)            The
provisions of Section 2.4 of the Base Indenture, which require the Issuer to maintain a Paying Agent, Registrar and Transfer Agent
in the Borough of Manhattan, State of New York with respect to Securities shall not apply to the Notes issued under this Thirteenth Supplemental
Indenture.

 

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	%

 

    	 	-15-	 

     

    

 

*              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 foregoing,
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.

 

(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.

 

    	 	-16-	 

     

    

 

(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.

 

(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.

 

(j)            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 Trustee or the Paying Agent in no event shall have any obligations whatsoever to determine the interest rate on the Notes
or a change in the applicable interest rate.

 

    	 	-17-	 

     

    

 

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, neither the Trustee nor the Paying
Agent shall have any 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 are to be redeemed or purchased in an offer to purchase at any time, the Registrar will select the
Notes for redemption or purchase on a pro rata basis subject to the Minimum Denominations requirement as near a pro rata
or by lot selection as is practicable in accordance with Euroclear and Clearstream guidelines, unless otherwise required by law or applicable
stock exchange or depositary requirements.

 

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

 

(c)            The
Registrar will promptly notify the Issuer in writing of the Notes selected for redemption or purchase and, in the case of any Note selected
for partial redemption or purchase, 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 series of a Holder are to be redeemed or purchased,
the entire outstanding amount of Notes of such series held by such Holder shall be redeemed or purchased. Except as provided in the preceding
sentence, provisions of the Indenture that apply to Notes called for redemption or purchase also apply to portions of Notes called for
redemption or purchase.

 

    	 	-18-	 

     

    

 

SECTION 3.2         Optional
Redemption.

 

(a)            Prior
to (i) in the case of the 2026 Notes, June 19, 2026 (one month before the maturity date of the 2026 Notes) and (ii) in
the case of the 2029 Notes, November 19, 2028 (two months before the maturity date of the 2029 Notes (the applicable date with respect
to each of the 2026 Notes and the 2029 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)            the
sum of the present values of the remaining scheduled payments of principal and interest (at the rate in effect on the date of calculation
of the redemption price) on the Notes to be redeemed that would be due if such Notes matured on the Applicable Par Call Date (exclusive
of interest accrued to the date of redemption) discounted to the date of redemption on an annual basis (ACTUAL/ ACTUAL (ICMA)) at the
Bund Rate plus 50 basis points in the case of the 2026 Notes and 50 basis points, in the case of the 2029 Notes; and

 

(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)            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 the Notes of such series of Notes being redeemed plus accrued
and unpaid interest thereon to the applicable redemption date (subject to the right of Holders of record on the relevant record date to
receive interest due on the relevant interest payment 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 this Section 3.2 shall be mailed or electronically
delivered (or otherwise transmitted in accordance with the Common 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 2026 Notes and 2029 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.

 

(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 Common
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 Common
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
for Tax Reasons.

 

If, as a result of any change in, or amendment to,
the laws (or any regulations or rulings promulgated under the laws) of the United States, or any change in, or amendments to, an official
position regarding the application or interpretation of such laws, regulations or rulings (including by virtue of a holding, judgment
or order by a court of competent jurisdiction or a change in published administrative practice), which change or amendment is announced
and becomes effective after the date of this Thirteenth Supplemental Indenture, the Issuer becomes or will become obligated to pay additional
amounts as described in Section 4.6 hereof with respect to the Notes, then the Issuer may, at any time at its option, redeem, in
whole, but not in part, the Notes on not less than 15 nor more than 60 days prior notice to the Holders, at a redemption price equal to
100% of their principal amount, together with accrued and unpaid interest and additional amounts, if any, on the Notes being redeemed
to, but excluding, the redemption date (subject to the rights of holders of record on the relevant record date to receive interest due
on the relevant interest date and additional amounts, if any, in respect thereof) and all additional amounts, if any, then due and which
will become due on the redemption date as a result of the redemption or otherwise; provided, however, that the notice of redemption shall
not be given earlier than 90 days before the earliest date on which the Issuer would be obligated to pay such additional amounts if a
payment in respect of the Notes were then due and unless at the time such notice is given such obligation to pay additional amounts remains
in effect (or will be in effect at the time of such redemption). Prior to any such notice of redemption, the Issuer will deliver to the
Trustee (a) an Officers’ Certificate stating that it is entitled to effect such redemption and that the obligation to pay additional
amounts cannot be avoided by taking reasonable measures available to it and (b) an Opinion of Counsel to the effect that the Issuer
has been or will become obligated to pay additional amounts. The Trustee and Paying Agent will accept and
will be entitled to conclusively rely upon the Officers’ Certificate and Opinion of Counsel as
sufficient evidence of the satisfaction of the conditions precedent described above for the Issuer to exercise its right to redeem the
Notes, which determination will be conclusive and binding on the Holders.

SECTION 3.5         Deposit
of Redemption Price.

  

Prior to 10:00 a.m. (London time) on the redemption
date or purchase date (including any purchase pursuant to Section 4.5), the Issuer shall deposit with the Trustee or with the Paying
Agent money sufficient to pay the redemption or purchase price of and accrued and unpaid interest and additional amounts, if any, and
premium, if any, on all Notes to be redeemed or purchased on that date.

 

SECTION 3.6         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;

 

    	 	-21-	 

     

    

 

(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

  

(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 (or, when the Notes are in the form of Global Securities, send pursuant to the applicable
procedures of the Common Depositary) 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.

 

    	 	-22-	 

     

    

 

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.

  

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 €100,000
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 and additional amounts, if any, 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 and additional amounts,
if any, 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;

 

    	 	-23-	 

     

    

 

(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

 

(iii)            deliver
or cause to be delivered to the Trustee the Notes properly accepted together with an Officers’ 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 distribute to each Holder of Notes properly tendered the Change of Control Payment for such Notes, and, upon
receipt of a Company Order, the Authenticating Agent 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 €100,000 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 under 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.

 

    	 	-24-	 

     

    

 

(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.

 

SECTION 4.6         Payment
of Additional Amounts.

  

All payments by the Issuer or any Guarantor on the
Notes or any Guarantee will be made free and clear of and without withholding or deduction for or on account of any present or future
tax, assessment or other governmental charges and any penalties, interest or additions to tax with respect thereto (each a “tax”)
imposed by the United States, unless the withholding or deduction of such taxes is required by law or the official interpretation or administration
thereof. If any taxes imposed by the United States are required to be withheld or deducted in respect of any payment made under or with
respect to the Notes or any Guarantee, the Issuer or applicable Guarantor will, subject to the exceptions and limitations set forth below,
pay additional amounts (the “additional amounts”) as are necessary in order that the net amounts received in respect
of such payments by each Beneficial Owner who is not a United States Person, after such withholding or deduction by any applicable withholding
agent (including any withholding or deduction in respect of such additional amounts) will equal the amounts which would have been received
in respect of such payments on any Note or Guarantee in the absence of such withholding or deduction; provided, however, that the
foregoing obligation to pay additional amounts shall not apply:

 

(a)            to
any tax to the extent such tax is imposed by reason of the Holder (or the Beneficial Owner for whose benefit such Holder holds such note),
or a fiduciary, settlor, beneficiary, member or stockholder of the Holder if the Holder is an estate, trust, partnership or corporation,
or a person holding a power over an estate or trust administered by a fiduciary holder, being considered as:

 

(i)             being
or having been engaged in a trade or business in the United States or having or having had a permanent establishment in the United States;

 

(ii)            having
or having had any other connection with the United States (other than a connection arising solely as a result of the ownership of such
Notes, the receipt of any payment or the enforcement of any rights under the Notes or any Guarantee), including being or having been a
citizen or resident of the United States;

 

(iii)            being
or having been a personal holding company, a passive foreign investment company or a controlled foreign corporation for United States
federal income tax purposes or a corporation that has accumulated earnings to avoid United States federal income tax;

 

(iv)            being
or having been a “10-percent shareholder” of the Parent Guarantor as defined in section 871(h)(3) of the United States
Internal Revenue Code of 1986, as amended (the “Code”); or

 

(v)            being
or having been a bank receiving payments on an extension of credit made pursuant to a loan agreement entered into in the ordinary course
of its trade or business, as described in section 881(c)(3)(A) of the Code or any successor provisions;

 

(b)            to
any Holder that is not the sole Beneficial Owner of such Notes, or a portion of such Notes, or that is a fiduciary, partnership or limited
liability company, but only to the extent that a Beneficial Owner with respect to the Holder, a beneficiary or settlor with respect to
the fiduciary, or a Beneficial Owner or member of the partnership or limited liability company would not have been entitled to the payment
of an additional amount had the beneficiary, settlor, Beneficial Owner or member received directly its beneficial or distributive share
of the payment;

 

    	 	-25-	 

     

    

 

(c)            to
any tax to the extent such tax would not have been imposed but for the failure of the Holder or the Beneficial Owner to comply with certification,
identification or other information reporting requirements concerning the nationality, residence, identity or connection with the United
States of the Holder or Beneficial Owner of such Notes, if compliance is required by statute, by regulation of the United States or any
taxing authority therein or by an applicable income tax treaty to which the United States is a party as a precondition to exemption from,
or reduction of, such tax, but only to the extent that the Holder or Beneficial Owner is legally eligible to provide such certification
or other evidence;

  

(d)            to
any tax that is imposed otherwise than by withholding or deduction in respect of a payment on the Notes or any Guarantee;

 

(e)            to
any estate, inheritance, gift, sales, transfer, wealth or similar tax;

 

(f)            to
any withholding or deduction that is imposed on a payment to a Holder or Beneficial Owner and that is required to be made pursuant to
any law implementing or complying with, or introduced in order to conform to, any European Union Directive on the taxation of savings;

 

(g)            to
any tax required to be withheld by any paying agent from any payment of principal of or interest on any note, if such payment can be made
without such withholding by at least one other paying agent;

 

(h)            to
any tax to the extent such tax would not have been imposed or levied but for the presentation by the Holder or Beneficial Owner of any
Note, where presentation is required, for payment on a date more than 30 days after the date on which payment became due and payable or
the date on which payment thereof is duly provided for, whichever occurs later;

 

(i)            to
any tax to the extent such tax is imposed or withheld solely by reason of the Beneficial Owner being a bank (i) purchasing such Notes
in the ordinary course of its lending business or (ii) that is neither (1) buying such Notes for investment purposes only nor
(2) buying such Notes for resale to a third-party that either is not a bank or holding such Notes for investment purposes only;

 

(j)            to
any tax imposed under sections 1471 through 1474 of the Code as of the issue date (or any amended or successor provision that is substantively
comparable and not materially more onerous to comply with), any current or future regulations or official interpretations thereof, any
agreement entered into pursuant to current section 1471(b) of the Code (or any amended or successor version described above) or any
fiscal or regulatory legislation, rules or practices adopted pursuant to any intergovernmental agreement (or related laws or official
administrative practices) implementing the foregoing; or

 

(k)            in
the case of any combination of clauses (a) through (j) of this Section 4.6.

 

The Notes are subject in all cases to any tax, fiscal
or other law or regulation or administrative or judicial interpretation applicable to the Notes. Except as specifically provided under
this Section 4.6, the Issuer (or any Guarantor, if applicable) will not be required to make any payment for any tax imposed by any
government or a political subdivision or taxing authority of or in any government or political subdivision.

 

    	 	-26-	 

     

    

 

 

The Issuer or applicable Guarantor shall use reasonable
efforts to obtain certified copies of tax receipts evidencing the payment of any taxes so deducted or withheld, or other evidence, and
shall provide such copies or other evidence to the Trustee. The Trustee shall not be obligated to inquire as to the veracity of such receipt
or other evidence.

 

The foregoing obligations will survive any termination,
defeasance or discharge of the Indenture and will apply mutatis mutandis to any successor to the Issuer or any Guarantor.

the amount of Indebtedness of the Guarantor is not increased thereby, (2) any Guarantor may merge into or transfer all or part of
its properties and assets to the Issuer or another Guarantor and (3) a transfer of assets or Capital Stock of any Guarantor shall

ARTICLE Six

GUARANTEE OF NOTES

 

SECTION 6.1         Guarantee.

 

Subject to the provisions of this Article Six,
each Guarantor, by execution of this Thirteenth Supplemental Indenture, jointly and severally, unconditionally guarantees to each Holder
(a) the due and punctual payment of the principal of, premium, interest and additional amounts, if any, 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 and additional amounts, if any, 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 Thirteenth 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, interest
and additional amounts, if any, 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.

 

    -29-

     

    

 

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 Officers’ 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 Officers’ Certificate
and an Opinion of Counsel to the effect that such release is permitted by the Indenture.

 

    -30-

     

    

 

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;

(c)           the
Issuer defaults in the performance of, or breaches any covenant, warranty or other agreement contained in the Indenture (other than a

(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

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

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:

 

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 Euros, Euro-Denominated
Designated Government Obligations or a combination of cash in Euros and Euro-Denominated Designated Government Obligations in amounts
as will be sufficient, without consideration of any reinvestment of interest, in the opinion of a nationally recognized firm of independent
accountants (in the event that Euro-Denominated Designated 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;

 

    -33-

     

    

 

(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 Officers’ 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, premium, interest or additional
amounts, 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).

 

(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
Thirteenth Supplemental Indenture and the operation of Article Five of this Thirteenth 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 Thirteenth Supplemental Indenture shall survive such satisfaction and discharge.

 

    -34-

     

    

 

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 Euros, Euro-Denominated Designated
Government Obligations or a combination of Euros and Euro-Denominated Designated Government Obligations 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 Euro-Denominated Designated Government Obligations are deposited), to pay the principal of, premium, interest or additional
amounts, 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;

 

(vi)          the
Issuer must deliver to the Trustee an Officers’ 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 Officers’ 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.

 

    -35-

     

    

 

SECTION 8.4        Application
of Trust Money.

 

The Trustee shall hold in trust money or Euro-Denominated
Designated Government Obligations (including proceeds thereof) deposited with it pursuant to this Article Eight. It shall apply the
deposited money and the money from Euro-Denominated Designated 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 Euro-Denominated Designated 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 Euro-Denominated Designated 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 Euro-Denominated Designated Government Obligations.

 

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

 

SECTION 8.7         Reinstatement.

 

If the Trustee or any Paying Agent is unable to apply
any money or Euro-Denominated Designated 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 Euro-Denominated Designated 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 Euro-Denominated Designated
Government Obligations held by the Trustee or any Paying Agent.

and may be used in lieu of the original instrument for all purposes. Signatures of the parties hereto transmitted by facsimile or PDF
shall be deemed to be their original signatures for all purposes.

 

All notices, approvals, consents,
requests and any communications hereunder must be in writing (provided that any communication sent to the Trustee hereunder must be in
the form of a document that is signed manually or by way of a digital signature provided by DocuSign (or such other digital signature
provider as specified in writing to Trustee by the authorized representative), in English). The Issuer agrees to assume all risks arising
out of the use of using digital signatures and electronic methods to submit communications to Trustee, including, without limitation,
the risk of Trustee acting on unauthorized instructions, and the risk of interception and misuse by third parties.

right to accept and act upon any notice, instruction, or other communication, including any funds transfer instruction, (each, a “Notice”)
received pursuant to the Indenture by electronic transmission (including by e-mail, facsimile transmission, web portal or other electronic
methods) and shall not have any duty to confirm that the person sending such Notice is, in fact, a person authorized to do so. Electronic
signatures believed by the Trustee to comply with the ESIGN Act of 2000 or other applicable law (including electronic images of handwritten
signatures and digital signatures provided by DocuSign, Orbit, Adobe Sign or any other digital signature provider identified by any other
party hereto and acceptable to the Trustee) shall be deemed original signatures for all purposes. Each other party to the Indenture assumes
all risks arising out of the use of electronic signatures and electronic methods to send notices to the Trustee, including without limitation
the risk of the Trustee acting on an unauthorized Notice and the risk of interception or misuse by third parties. Notwithstanding the
foregoing, the Trustee may in any instance and in its sole discretion require that a Notice in the form of an original document bearing
a manual signature be delivered to the Trustee in lieu of, or in addition to, any such electronic Notice.

SECTION 13.12     Regulatory

Agent shall be entitled to ask for documentation to verify such entity’s formation and legal existence as well as financial statements,
licenses, identification and authorisation documents from individuals claiming authority to represent the entity or other relevant documentation.

If the Paying Agent or any of their directors know or suspect that a payment is the proceeds of criminal conduct, such person is required
to report such information pursuant to the applicable authorities and such report shall not be treated as a breach by such person of any
confidentiality covenant or other restriction imposed on such person under this Thirteenth Supplemental Indenture, by law or otherwise
on the disclosure of information. The Paying Agent shall be indemnified and held harmless by the Issuer from and against all losses suffered
by them that may arise as a result of the agents being prevented from fulfilling their obligations hereunder due to the extent doing so
would not be consistent with applicable statutory anti-money laundering requirements.

 

(d)            Notwithstanding
anything to the contrary in this Thirteenth Supplemental Indenture or in any other agreement, arrangement or understanding among any such
parties, each party hereto acknowledges that any liability of any party arising under this Thirteenth Supplemental Indenture or any such
other document, to the extent such liability is unsecured or not otherwise exempted, may be subject to the write-down and conversion powers
of a Resolution Authority and agrees and consents to, and acknowledges and agrees to be bound by:

 

(i)            the
application of any Write-Down and Conversion Powers by a Resolution Authority to any such liabilities arising hereunder which may be payable
to it by any party hereto; and

effects of any Bail-in Action on any such liability, including, if applicable:

or cancellation of any such liability;

 

(II) a conversion of all, or a portion
of, such liability into shares or other instruments of ownership in such party, its parent undertaking, or a bridge institution that may
be issued to it or otherwise conferred on it, and that such shares or other instruments of ownership will be accepted by it in lieu of
any rights with respect to any such liability under this Thirteenth Supplemental Indenture or any other agreement; or

 

(III) the variation of the terms of
such liability in connection with the exercise of the write-down and conversion powers of any Resolution Authority.

CELANESE US HOLDINGS LLC, a Delaware limited liability
company (the “Issuer”), promises to pay interest on the principal amount of this 2026 Note at the rate per annum shown
above, subject to adjustment as set forth in Section 2.4 of the Thirteenth Supplemental Indenture. The Issuer shall pay interest
annually on July 19 of each year, commencing July 19, 2023, and on the final maturity date of the 2026 Notes. If such date is
not a Business Day, interest will be paid to registered Holders on the next succeeding Business Day and no additional interest will be
due as a result in accordance with Section 10.6 of the Base Indenture. Interest on the 2026 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 19, 2022
until the principal hereof is due. Interest shall be computed on the basis of the actual number of days in the period for which interest
is being calculated and the actual number of days from and including the last date on which interest was paid on the 2026 Notes (or July 19,
2022, if no interest has been paid on the 2026 Notes), to but excluding the next scheduled interest payment date. The Issuer shall pay
interest on overdue principal and premium, if any, at the rate borne by the 2026 Notes, and it shall pay interest on overdue installments
of interest at the same rate to the extent lawful.

 

2.            Method
of Payment

 

The Issuer shall pay interest and additional amounts,
if any, on the 2026 Notes (except defaulted interest) to the Persons who are registered Holders at the close of business on the July 5
next preceding the interest payment date even if 2026 Notes are canceled after the record date and on or before the interest payment date
(whether or not a Business Day). Holders must surrender 2026 Notes to a Paying Agent to collect principal payments. The Issuer shall pay
principal, premium, if any, and interest in money of the member states of the European Union that have adopted or that adopt the single
currency in accordance with the treaty establishing the European Community, as amended by the Treaty on European Union, that at the time
of payment is legal tender for payment of public and private debts. Payments in respect of the 2026 Notes represented by a Global Security
(including principal, premium, interest and additional amounts, if any) shall be made by wire transfer of immediately available funds
to the accounts specified by the Holders to the Paying Agent or the Issuer. The Issuer will make all payments in respect of a certificated
2026 Note (including principal, premium, interest and additional amounts, if any), at the office of each Paying Agent, except that, at
the option of the Issuer, payment of interest may be made by mailing a check to the registered address of each Holder thereof. Such payment
will be in Euros.

Agent and Registrar

company (the “Issuer”), promises to pay interest on the principal amount of this 2029 Note at the rate per annum shown
above, subject to adjustment as set forth in Section 2.4 of the Thirteenth Supplemental Indenture. The Issuer shall pay interest
annually on January 19 of each year, commencing January 19, 2023, and on the final maturity date of the 2029 Notes. If such
date is not a Business Day, interest will be paid to registered Holders on the next succeeding Business Day and no additional interest
will be due as a result in accordance with Section 10.6 of the Base Indenture. Interest on the 2029 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 19,
2022 until the principal hereof is due. Interest shall be computed on the basis of the actual number of days in the period for which interest
is being calculated and the actual number of days from and including the last date on which interest was paid on the 2029 Notes (or July 19,
2022, if no interest has been paid on the 2029 Notes), to but excluding the next scheduled interest payment date. The Issuer shall pay
interest on overdue principal and premium, if any, at the rate borne by the 2029 Notes, and it shall pay interest on overdue installments
of interest at the same rate to the extent lawful.

 

2.            Method
of Payment

 

The Issuer shall pay interest and additional amounts,
if any, on the 2029 Notes (except defaulted interest) to the Persons who are registered Holders at the close of business on the January 5
next preceding the interest payment date even if 2029 Notes are canceled after the record date and on or before the interest payment date
(whether or not a Business Day). Holders must surrender 2029 Notes to a Paying Agent to collect principal payments. The Issuer shall pay
principal, premium, if any, and interest in money of the member states of the European Union that have adopted or that adopt the single
currency in accordance with the treaty establishing the European Community, as amended by the Treaty on European Union, that at the time
of payment is legal tender for payment of public and private debts. Payments in respect of the 2029 Notes represented by a Global Security
(including principal, premium, interest and additional amounts, if any) shall be made by wire transfer of immediately available funds
to the accounts specified by the Holders to the Paying Agent or the Issuer. The Issuer will make all payments in respect of a certificated
2026 Note (including principal, premium, interest and additional amounts, if any), at the office of each Paying Agent, except that, at
the option of the Issuer, payment of interest may be made by mailing a check to the registered address of each Holder thereof. Such payment
