The following terms relate
to the Offered Securities:

 

(1)            The
Offered Securities constitute a series of securities having the title “2.750% Senior Notes due 2031”.

 

(2)            The
initial aggregate principal amount of the Offered Securities that may be authenticated and delivered under the Base Indenture (except
for Offered Securities authenticated and delivered upon registration of transfer of, or in exchange for, or in lieu of, other Offered
Securities pursuant to Section 2.05, 2.06, 2.07, 2.11, or 3.03 of the Base Indenture) is $300,000,000. The aggregate amount of Additional

(3)            The
entire Outstanding principal of the Offered Securities shall be payable on November 15, 2031.

 

(4)            The
rate at which the Offered Securities shall bear interest shall be 2.750% per year, as set forth in Section 1 of the form of Offered
Security attached hereto as Exhibit A and subject to adjustment as set forth in Section 2 of the form of Offered Security attached
hereto as Exhibit A. The date from which interest shall accrue on the Offered Securities shall be November 23, 2021 or the most
recent Interest Payment Date to which interest has been paid or provided for. The Interest Payment Dates for the Offered Securities shall
be May 15 and November 15 of each year, beginning on May 15, 2022. Interest shall be payable on each Interest Payment Date
to the Holders of record at the close of business on the May 1 and November 1 immediately prior to each Interest Payment Date
(a “regular record date”); however, interest payable at maturity will be paid to the Person to whom principal is payable.
The basis upon which interest shall be calculated shall be that of a 360-day year consisting of twelve 30-day months. If any Interest
Payment Date of the Offered Securities would otherwise be a day that is not a Business Day, that Interest Payment Date will be postponed
to the next date that is a Business Day and no interest will accrue on the amounts so payable for the period from and after such date
to the next Business Day. If the maturity date of the Offered Securities falls on a day that is not a Business Day, the related payment
of principal and interest will be made on the next Business Day as if it were made on the date such payment was due, and no interest will
accrue on the amounts so payable for the period from and after such date to the next Business Day.

 

(5)            The
Offered Securities shall be issuable in whole in the registered form of one or more Global Securities, and the Depositary for such Global
Securities shall be The Depository Trust Company, New York, New York. The Offered Securities shall be substantially in the form attached
hereto as Exhibit A, the terms of which are incorporated by reference in this Fourth Supplemental Indenture. The Offered Securities
shall be issuable in denominations of $2,000 or any integral multiple of $1,000 in excess thereof.

 

(6)            The
Offered Securities shall be subject to redemption at the Company's option on any Redemption Date as set forth in Section 6 of the
form of Offered Security attached hereto as Exhibit A.

(7)            Except
as provided in this Fourth Supplemental Indenture, the Offered Securities shall not be subject to redemption, repurchase or repayment
at the option of any Holder thereof, upon the occurrence of any particular circumstances or otherwise. The Offered Securities shall not
have the benefit of any sinking fund. For the avoidance of doubt, the Company, the Guarantor and their respective Affiliates may purchase
Offered Securities from the Holders thereof from time to time, either in the open market at prevailing prices or in private transactions
at negotiated prices. Any Offered Securities purchased by the Company, the Guarantor or any of their respective Affiliates may, at the
purchaser’s discretion, be held, resold or canceled.

 

(8)            Except
as provided in this Fourth Supplemental Indenture, the Holders of the Offered Securities shall have no special rights in addition to those
provided in the Base Indenture upon the occurrence of any particular events.

 

(9)            The
Offered Securities shall be general unsecured and unsubordinated obligations of the Company and shall be ranked equally among themselves.

 

(10)          The
Offered Securities are not convertible into shares of common stock or other securities of the Company or the Guarantor.

 

(11)          In
addition to the provisions of the Base Indenture referred to in Section 11.03(b) thereof, the covenants described in Sections
1.3(1), 1.3(2) and 1.3(3) of this Fourth Supplemental Indenture shall be subject to the Company’s covenant defeasance
right set forth in Section 11.03 of the Base Indenture. In addition, following any such covenant defeasance, the Events of Default
set forth in Sections 1.4(3), 1.4(4), 1.4(5) (as it relates to the provisions of Section 1.3(3)), 1.4(6) and 1.4(7) of
this Fourth Supplemental Indenture shall cease to apply with respect to the Offered Securities.

 

Section 1.2 Additional Defined Terms.

 

As used in this Fourth Supplemental
Indenture, the following defined terms shall have the following meanings with respect to the Offered Securities only:

 

“Attributable Debt”,
in connection with a Sale and Lease-Back Transaction, as of any particular time, means the aggregate of the present values (discounted
at a rate that, at the inception of the lease, represents the effective interest rate that the lessee would have incurred to borrow over
a similar term the funds necessary to purchase the leased assets) of the obligations of the Company, the Guarantor or any Restricted Subsidiary
for net rental payments during the remaining term of the applicable lease, including any period for which such lease has been extended
or, at the option of the lessor, may be extended. The term “net rental payments” under any lease of any period shall
mean the sum of the rental and other payments required to be paid in such period by the lessee thereunder, not including any amounts required
to be paid by such lessee, whether or not designated as rental or additional rental, on account of maintenance and repairs, reconstruction,
insurance, taxes, assessments, water rates or similar charges required to be paid by such lessee thereunder or any amounts required to
be paid by such lessee thereunder contingent upon the amount of sales, maintenance and repairs, reconstruction, insurance, taxes, assessments,
water rates or similar charges.

means each Monday, Tuesday, Wednesday, Thursday and Friday which is not a day on which banking institutions in The City of New York are
authorized or obligated by law or executive order to close.

 

“Change of Control”
means the occurrence on or after the Issue Date of any of the following: (1) the direct or indirect sale, lease, transfer, conveyance
or other disposition (other than by way of merger or consolidation or as a pledge for security purposes only), in one or more series of
related transactions, of all or substantially all of the assets of Parent and its Subsidiaries, taken as a whole, to any person, other
than Parent and/or a direct or indirect wholly-owned Subsidiary of Parent; (2) the consummation of any transaction (including, without
limitation, any merger or consolidation) the result of which is that any person becomes the “beneficial owner” (as defined
in Rules 13d-3 and 13d-5 under the Exchange Act), directly or indirectly, of more than 50% of Parent’s outstanding Voting Stock
or other Voting Stock into which Parent's Voting Stock is reclassified, consolidated, exchanged or changed, measured by voting power rather
than number of shares; (3) Parent consolidates with, or merges with or into, any person, or any person consolidates with, or merges
with or into, Parent, in any such event pursuant to a transaction in which any of Parent’s outstanding Voting Stock or the Voting
Stock of such other person is converted into or exchanged for cash, securities or other property, other than any such transaction where
the shares of Parent’s Voting Stock outstanding immediately prior to such transaction constitute, or are converted into or exchanged
for, at least a majority of the Voting Stock of the surviving person or any direct or indirect parent company of the surviving person
immediately after giving effect to such transaction; or (4) the approval by the holders of Parent's Voting Stock of a plan for Parent’s
liquidation or dissolution. Notwithstanding the foregoing, a transaction shall not be deemed to involve a Change of Control under clause
(1), (2) or (4) above if: (i) Parent becomes a direct or indirect wholly-owned Subsidiary of a holding company or a holding
company becomes the successor to Parent under the Indenture pursuant to a transaction that is permitted under the Indenture and (ii) the
direct or indirect holders of the Voting Stock of such holding company immediately following that transaction (or a series of related
transactions) are the same or substantially the same (and hold in the same or substantially the same proportions) as the holders of Parent’s
Voting Stock immediately prior to that transaction. The term “person”, as used in this definition, means any Person and any
two or more Persons as provided in Section 13(d)(3) of the Exchange Act.

 

“Change of Control
Triggering Event” means the occurrence of both a Change of Control and a Rating Event; provided, however, that a Change of Control
Triggering Event otherwise arising by virtue of a particular reduction in rating shall not be deemed to have occurred in respect of a
Change of Control if the Rating Agency or Rating Agencies making the reduction in rating to which this definition would otherwise apply
do not announce or publicly confirm or inform the Trustee in writing at the Company’s request that the reduction was the result,
in whole or in part, of any event or circumstance comprised of or arising as a result of, or in respect of, the applicable Change of Control
(whether or not the applicable Change of Control shall have occurred at the time of the purported Change of Control Triggering Event).
Unless both Rating Agencies are providing a rating for the Offered Securities at the commencement of any period referred to in the definition
of “Rating Event”, a Rating Event shall be deemed to have occurred during such period. Notwithstanding the foregoing, no Change
of Control Triggering Event shall be deemed to have occurred in connection with any particular Change of Control unless and until such
Change of Control has actually been consummated.

(n)            any
extension, renewal or replacement (or successive extensions, renewals or replacements) in whole or in part, of any Lien referred to in
the foregoing clauses (a) to (m), inclusive; provided, however, that the principal amount of Indebtedness secured thereby (except
to the extent otherwise excepted under clauses (a) through (m)) shall not exceed the principal amount of Indebtedness so secured
at the time of such extension, renewal or replacement, and that such extension, renewal or replacement shall be limited to all or a part
of the assets, or any replacements therefor and products and proceeds thereof, that secured the Lien so extended, renewed or replaced,
plus improvements and construction on real property.

 

    	 	 11	 
	 	Fourth Supplemental Indenture	 

     

    

 

Notwithstanding the foregoing,
any Liens securing the Offered Securities granted pursuant to this Section 1.3(1) shall be automatically released and discharged
upon the release by all Holders of the Indebtedness secured by the Lien giving rise to the Lien securing the Offered Securities (including
any deemed release upon payment in full of all obligations under such Indebtedness), or, with respect to any particular Principal Property,
upon any sale, exchange or transfer to any Person not an Affiliate of Parent or the Company of such Principal Property.

 

(2)            Limitation
on Sale and Lease-Back Transactions.

 

Neither the Company nor the
Guarantor shall, and neither of them shall permit any Restricted Subsidiary to, enter into any Sale and Lease-Back Transaction (other
than with the Company, the Guarantor and/or one or more Subsidiaries of the Guarantor) unless:

 

(a)            the
Company, the Guarantor or such Restricted Subsidiary, at the time of entering into such Sale and Lease-Back Transaction, would be entitled
to incur Indebtedness secured by a Lien on the Principal Property to be leased in an amount at least equal to the Attributable Debt in
respect of such Sale and Lease-Back Transaction, without equally and ratably securing the Offered Securities pursuant to Section 1.3(1) of
this Fourth Supplemental Indenture; or

 

(b)            the
direct or indirect proceeds of the sale of the Principal Property to be leased are at least equal to the fair value of such Principal
Property, as determined by Parent’s Board of Directors, and an amount equal to the net proceeds from the sale of the property or
assets so leased is applied, within 180 days of the effective date of any such Sale and Lease-Back Transaction, to the purchase or acquisition,
or, in the case of real property, commencement of the construction of property or assets or to the retirement (other than at maturity
or pursuant to a mandatory sinking fund or mandatory redemption provision) of Offered Securities, or of Funded Indebtedness of Parent
or a consolidated Subsidiary ranking on a parity with or senior to the Offered Securities; provided that there shall be credited to the
amount of net proceeds required to be applied pursuant to this clause (b) an amount equal to the sum of (i) the principal amount
of Offered Securities delivered within 180 days of the effective date of such Sale and Lease-Back Transaction to the Trustee for retirement
and cancellation and (ii) the principal amount of other Funded Indebtedness voluntarily retired by Parent or a consolidated Subsidiary
ranking on a parity with or senior to the Offered Securities within such 180-day period, excluding retirements of Offered Securities and
other Funded Indebtedness as a result of conversions or pursuant to mandatory sinking fund or mandatory prepayment provisions.

(3)            Change
of Control Triggering Event.

 

(a)            If
a Change of Control Triggering Event with respect to the Offered Securities occurs, unless the Company has exercised its option to redeem
the Offered Securities, it shall be required to make an offer (a “Change of Control Offer”) to each Holder of the Offered
Securities to repurchase, at the Holder’s election, all or any part (equal to $2,000 or an integral multiple of $1,000 in excess
thereof) of that Holder’s Offered Securities on the terms set forth in this Fourth Supplemental Indenture. In a Change of Control
Offer, the Company shall be required to offer payment in cash equal to 101% of the aggregate principal amount of the Offered Securities
repurchased, plus accrued and unpaid interest, if any, on the Offered Securities repurchased to, but excluding, the date of repurchase
(a “Change of Control Payment”). Within 30 days following any Change of Control Triggering Event with respect to the
Offered Securities or, at the Company's option, prior to any Change of Control with respect to the Offered Securities, but after public
announcement of the transaction that constitutes or may constitute the Change of Control, a notice shall be sent to the Trustee and to
the Holders of the Offered Securities describing in reasonable detail the transaction that constitutes or may constitute the Change of
Control Triggering Event and offering to repurchase the Offered Securities on the date specified in the notice, which date shall, except
as described in the immediately following sentence, be no earlier than 30 days and no later than 60 days from the date such notice is
sent (or, in the case of a notice prior to the consummation of the Change of Control Triggering Event, no earlier than 30 days nor later
than 60 days from the Change of Control Triggering Event) other than as may be required by law (a “Change of Control Payment
Date”). The notice shall, if sent prior to the date of consummation of the Change of Control, state that the offer to purchase
is conditioned on the Change of Control Triggering Event occurring on or prior to the Change of Control Payment Date.

 

(b)            If
the Change of Control Payment Date falls on a day that is not a Business Day, the related payment of the Change of Control Payment will
be made on the next Business Day as if it were made on the date such payment was due, and no interest will accrue on the amounts so payable
for the period from and after such date to the next Business Day.

 

(c)            In
order to accept the Change of Control Offer, the Holder must deliver (or otherwise comply with alternative instructions in accordance
with the procedures of the Depositary) to the paying agent, at least five Business Days prior to the Change of Control Payment Date, its
Offered Security together with the form entitled “Election Form” (which form is contained in the form of Offered Security
attached hereto as Exhibit A) duly completed, or a telegram, telex, facsimile transmission or a letter from a member of a national
securities exchange, or the Financial Industry Regulatory Authority, Inc. or a commercial bank or trust company in the United States
setting forth:

 

(i)            the
name of the Holder of such Offered Security;

 

    	 	 13	 
	 	Fourth Supplemental Indenture	 

     

    

 

(ii)            the
principal amount of such Offered Security;

 

(iii)            the
principal amount of such Offered Security to be repurchased;

 

(iv)            the
certificate number or a description of the tenor and terms of such Offered Security;

 

(v)            a
statement that the Holder is accepting the Change of Control Offer; and

 

(vi)            a
guarantee that such Offered Security, together with the form entitled “Election Form” duly completed, shall be received by
the paying agent at least five Business Days prior to the Change of Control Payment Date.

 

(d)            Any
exercise by a Holder of its election to accept the Change of Control Offer shall be irrevocable. The Change of Control Offer may be accepted
for less than the entire principal amount of an Offered Security, but in that event the principal amount of such Offered Security remaining
Outstanding after repurchase must be equal to $2,000 or an integral multiple of $1,000 in excess thereof.

 

(e)            On
the Change of Control Payment Date, the Company shall, to the extent lawful:

 

(i)            accept
for payment all Offered Securities or portions of such Offered Securities 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 Offered Securities or portions of Offered Securities
properly tendered; and

 

(iii)            deliver
or cause to be delivered to the Trustee the Offered Securities properly accepted together with an Officers' Certificate stating the aggregate
principal amount of Offered Securities or portions of Offered Securities being repurchased.

 

(f)            The
Company shall not be required to make a Change of Control Offer upon the occurrence of a Change of Control Triggering Event if a third
party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Company
and the third party purchases all Offered Securities properly tendered and not withdrawn under its offer. In addition, the Company shall
not repurchase any Offered Securities if there has occurred and is continuing on the Change of Control Payment Date an Event of Default
under the Base Indenture (as supplemented by this Fourth Supplemental Indenture), other than a default in the payment of the Change of
Control Payment upon a Change of Control Triggering Event.

 

    	 	 14	 
	 	Fourth Supplemental Indenture	 

     

    

 

(g)            Notwithstanding
the foregoing, the Company and the Guarantor shall comply with the requirements of Rule 14e-1 under the Securities Exchange Act of
1934, as amended (the “Exchange Act”), and any other securities laws and regulations thereunder to the extent those
laws and regulations are applicable in connection with the repurchase of the Offered Securities as a result of a Change of Control Triggering
Event. To the extent that the provisions of any such securities laws or regulations conflict with this Section 1.3(3), neither the
Company nor the Guarantor shall be deemed to have breached its obligations under this Section 1.3(3) by virtue of its compliance
with such securities laws or regulations.

 

(4)            Limitation
on Mergers and Other Transactions.

 

Each of the Company and the
Guarantor covenants that it will not merge or consolidate with any other Person or sell or convey all or substantially all of its assets
in one transaction or a series of related transactions to any Person, unless:

 

(a)            either
the Company or the Guarantor, as the case may be, shall be the continuing entity, or the successor entity or the Person which acquires
by sale or conveyance substantially all the assets of the Company or the Guarantor, as the case may be (if other than the Company or the
Guarantor, as the case may be), (A) shall expressly assume the due and punctual payment of the principal of, premium, if any, and
interest on the Offered Securities or the obligations under the Parent guarantee, as the case may be, according to their tenor, and the
due and punctual performance and observance of all of the covenants and agreements of the Base Indenture (as supplemented by this Fourth
Supplemental Indenture) to be performed or observed by the Company or the Guarantor, as the case may be, by supplemental indenture reasonably
satisfactory to the Trustee, executed and delivered to the Trustee by such person, (B) shall be an organization treated as a “corporation”
for United States federal tax purposes under the laws of the United States, any state thereof or the District of Columbia, Luxembourg, Ireland,
England and Wales, Jersey, any member state of the European Union as in effect on the date the Offered Securities are first issued, or
Switzerland, (C) shall agree to pay any Additional Amounts with respect to any withholding or deduction of Taxes or any payment on
the Offered Securities or the Parent guarantee (as applicable) imposed by any jurisdiction in which such successor entity is incorporated
or otherwise a resident for tax purposes pursuant to the terms set forth and, subject to the exceptions described in, Section 14.02
of the Base Indenture and (D) shall obtain either (x) an opinion, in form and substance reasonably acceptable to the Trustee,
of tax counsel of recognized standing reasonably acceptable to the Trustee, which counsel shall include Foley & Lardner LLP,
or (y) a ruling from the United States Internal Revenue Service, in either case to the effect that such merger or consolidation,
or such sale or conveyance, will not result in an exchange of the Offered Securities for new debt instruments for United States federal
income tax purposes; and

 

(b)            no
Event of Default (as defined below) and no event that, after notice or lapse of time or both, would become an Event of Default shall be
continuing immediately after such merger or consolidation, or such sale or conveyance.

 

    	 	 15	 
	 	Fourth Supplemental Indenture	 

     

    

 

The Company shall deliver
to the Trustee prior to or simultaneously with the consummation of the proposed transaction an Officer’s Certificate to the foregoing
effect and an Opinion of Counsel stating that the proposed transaction and any such supplemental indenture comply with the Base Indenture
(as supplemented by this Fourth Supplemental Indenture).

 

Section 1.4 Events of Default.

 

Solely with respect to the
Offered Securities, the provisions set forth below shall replace in their entirety Sections 6.01(a) and (b) of the Base Indenture:

 

“(a) Whenever used
herein with respect to the Offered Securities, “Event of Default” means any one or more of the following events that has occurred
and is continuing:

 

(1)            default
in the payment of any installment of interest upon any of the Offered Securities as and when the same shall become due and payable, and
continuance of such default for a period of 30 days;

 

(2)            default
in the payment of all or any part of the principal of or premium, if any, on any of the Offered Securities as and when the same shall
become due and payable either at maturity, upon redemption, by declaration or otherwise;

 

(3)            default
in the performance or breach by the Company or the Guarantor of the covenant described under Section 1.3(4) of this Fourth Supplemental
Indenture;

 

(4)            failure
by the Company for 60 days from receipt of written notice by the Trustee or the Holders of at least 25% of the principal amount of the
Offered Securities Outstanding to comply with the provisions under Section 1.3(3) of this Fourth Supplemental Indenture;

 

(5)            default
in the performance, or breach, of any covenant or agreement of the Company or the Guarantor in respect of the Offered Securities and the
related guarantee (other than a default or breach that is specifically dealt with elsewhere), and continuance of such default or breach
for a period of 90 days after the date on which there has been given, by registered or certified mail, to the Company or the Guarantor
by the Trustee or to the Company or the Guarantor and the Trustee by the Holders of at least 25% in principal amount of the Outstanding
Offered Securities, a written notice specifying such default or breach and requiring it to be remedied and stating that the notice is
a “Notice of Default” under the Indenture;

 

(6)            the
Parent guarantee with respect to the Offered Securities shall for any reason cease to be, or shall for any reason be asserted in writing
by the Company or the Guarantor not to be, in full force and effect and enforceable in accordance with its terms except to the extent
contemplated by the Base Indenture, the Fourth Supplemental Indenture and such guarantee;

 

    	 	 16	 
	 	Fourth Supplemental Indenture	 

     

    

 

(7)            an
event of default shall happen and be continuing with respect to any Indebtedness (other than Non-Recourse Indebtedness) of the Company,
the Guarantor or any Restricted Subsidiary under any indenture or other instrument evidencing or under which the Company, the Guarantor
or any Restricted Subsidiary shall have a principal amount outstanding (such amount with respect to original issue discount bonds or zero
coupon notes, bonds or debentures or similar securities based on the accreted amount determined in accordance with GAAP and as of the
date of the most recently prepared consolidated balance sheet of the Company, the Guarantor or any Restricted Subsidiary, as the case
may be) in excess of $100,000,000, and such event of default shall involve the failure to pay the principal of such Indebtedness on the
final maturity date thereof after the expiration of any applicable grace period with respect thereto, or such Indebtedness shall have
been accelerated so that the same shall have become due and payable prior to the date on which the same would otherwise have become due
and payable, and such acceleration shall not be rescinded or annulled within 30 days after notice thereof shall have been given to the
Company by the Trustee, or to the Company and the Trustee by the Holders of at least 25% in aggregate principal amount of the Outstanding
Offered Securities; provided, however, that:

 

(a)            if
such event of default under such indenture or instrument shall be remedied or cured by the Company or the Guarantor or waived by the requisite
holders of such Indebtedness, then the Event of Default hereunder by reason thereof shall be deemed likewise to have been thereupon remedied,
cured or waived without further action upon the part of either the Trustee or any of the Holders; and

 

(b)            subject
to the provisions of Sections 7.01 and 7.02 of the Base Indenture, the Trustee shall not be charged with actual knowledge of any such
event of default unless written notice thereof shall have been given to a Responsible Officer of the Trustee by the Company or the Guarantor,
as the case may be, by the holder or an agent of the holder of any such Indebtedness, by the trustee then acting under any indenture or
other instrument under which such default shall have occurred, or by the Holders of not less than 25% in the aggregate principal amount
of Outstanding Offered Securities.

 

(8)            a
court having jurisdiction in the premises shall enter a decree or order for relief in respect of the Company or the Guarantor in an involuntary
case under any applicable bankruptcy, insolvency or other similar law now or hereafter in effect, or appointing a receiver, liquidator,
assignee, custodian, trustee or sequestrator or similar official of the Company or the Guarantor or for any substantial part of its property
or ordering the winding up or liquidation of its affairs, and such decree or order shall remain unstayed and in effect for a period of
90 consecutive days; or

 

(9)            the
Company or the Guarantor shall commence a voluntary case under any applicable bankruptcy, insolvency or other similar law now or hereafter
in effect, or consent to the entry of an order for relief in an involuntary case under any such law, or consent to the appointment of
or taking possession by a receiver, liquidator, assignee, custodian, trustee or sequestrator or similar official of the Company or Parent
or for any substantial part of its property, or make any general assignment for the benefit of creditors.

	 	Fourth Supplemental Indenture	 

     

    

 

(b) If an Event of Default
shall have occurred and be continuing in respect of the Offered Securities, in each and every case (other than an Event of Default described
in the eighth and ninth paragraphs above), unless the principal of all the Offered Securities shall have already become due and payable,
either the Trustee at the written request of the Holder or Holders of not less than 25% in aggregate principal amount of the Offered Securities
then Outstanding, by notice in writing to the Company and the Guarantor, as applicable, and to the Trustee if given by such Holder or
Holders, may declare the unpaid principal and accrued and unpaid interest of all the Offered Securities to be due and payable immediately.
If an Event of Default described in the eighth or ninth paragraphs above shall have occurred in respect of the Offered Securities, the
unpaid principal and accrued and unpaid interest of all the Offered Securities shall be due and payable immediately, without any declaration
or other act on the part of the Trustee or the Holders.”

 

Section 1.5 Additional Notes.

 

The
Company may, without the consent of the Holders of the outstanding Offered Securities, issue additional debt securities of such
series (“Additional Notes”), which Additional Notes shall have the same terms as the outstanding Offered Securities
except for the issue price, date of issuance, and under some circumstances, the first interest payment date; provided that if Additional
Notes are not fungible with the then outstanding Offered Securities for U.S. federal income tax purposes, such Additional Notes shall
be issued with a separate CUSIP code from the outstanding Offered Securities. Additional Notes issued in this manner shall form a single
series with the outstanding Offered Securities for all purposes under the Indenture.

be issued in one or more series under and pursuant to an Indenture for the Company's unsubordinated debt securities, dated as of March 26,
2018, as supplemented by the Third Supplemental Indenture, dated as of April 30, 2018 (the “Base Indenture”),
duly executed and delivered by and among the Company, nVent Electric plc, an Irish public limited company (“Parent”
or the “Guarantor”), and U.S. Bank National Association, a national banking association (the “Trustee”),
as supplemented by the Fourth Supplemental Indenture, dated as of November 23, 2021 (the “Fourth Supplemental Indenture”),
by and among the Company, the Guarantor and the Trustee. The Base Indenture as supplemented and amended by the Fourth Supplemental Indenture
is referred to herein as the “Indenture.” By the terms of the Base Indenture, the debt securities issuable thereunder
are issuable in series that may vary as to amount, date of maturity, rate of interest and in other respects as provided in the Base Indenture.
This security is one of the series designated on the face hereof (individually, a “Security,” and collectively, the
 “Securities”), and reference is hereby made to the Indenture for a description of the rights, limitations of rights,
obligations, duties and immunities of the Trustee, the Company, the Guarantor and the holders of this Security (the “Securityholders”).
Capitalized terms used herein and not otherwise defined shall have the meanings given them in the Base Indenture or in the Fourth Supplemental
Indenture, as applicable.

 

1.            Interest.
The Company promises to pay interest on the principal amount of this Security at an annual rate of 2.750% (the “Original Interest
Rate”), subject to adjustment pursuant to Section 2 of this Security. The Company shall pay interest semi-annually on May 15
and November 15 of each year (each such day, an “Interest Payment Date”). If any Interest Payment Date, redemption
date or maturity date of this Security is not a Business Day, then payment of interest or principal (and premium, if any) shall be made
on the next succeeding Business Day with the same force and effect as if made on the date such payment was due, and no interest shall
accrue for the period after such date to the date of such payment on the next succeeding Business Day. Interest on the Securities shall
accrue from the most recent date to which interest has been paid or duly provided for or, if no interest has been paid, from the date
of issuance; provided that, if there is no existing Default in the payment of interest, and if this Security is authenticated between
a regular record date referred to on the face hereof and the next succeeding Interest Payment Date, interest shall accrue from such next
succeeding Interest Payment Date; and provided, further, that the first Interest Payment Date shall be May 15, 2022. Interest shall
be calculated on the basis of a 360-day year consisting of twelve 30-day months.

 

    A-4

     

    

 

2.            Interest
Rate Adjustment.   The interest rate payable on this Security shall be subject to adjustment from time to time if either
Fitch or S&P (or, if applicable, a “nationally recognized statistical rating organization” within the meaning of Section 3(a)(62)
under the Exchange Act selected by the Company as a replacement for Fitch or S&P, or both, as the case may be (each, a “Substitute
Rating Agency”)) downgrades (or subsequently upgrades) its rating assigned to the Securities, as set forth in this Section 2.
Each of Fitch, S&P and any Substitute Rating Agency is an “Interest Rate Rating Agency,” and together they are
 “Interest Rate Rating Agencies.”

 

If the rating of the Securities
from one or both of Fitch or S&P (or, if applicable, any Substitute Rating Agency) is decreased to a rating set forth in either of
the tables set forth in this Section 2, the interest rate shall increase from the Original Interest Rate by an amount equal to the
sum of the percentages per annum set forth in the following tables opposite those ratings:

 

	Fitch
    Rating*	 	Percentage	 
	BB+	 	 	0.25	%
	BB	 	 	0.50	%
	BB-	 	 	0.75	%
	B+
    or below	 	 	1.00	%

 

	S&P
    Rating*	 	Percentage	 
	BB+	 	 	0.25	%
	BB	 	 	0.50	%
	BB-	 	 	0.75	%
	B+
    or below	 	 	1.00	%

 

 

 

*            Including
the equivalent ratings of any Substitute Rating Agency therefor.

 

For purposes of making adjustments
to the interest rate payable on this Security, the following rules of interpretation shall apply:

 

(1)            if
at any time less than two Interest Rate Rating Agencies provide a rating on the Securities for reasons not within Parent’s control
(i) the Company shall use commercially reasonable efforts to obtain a rating on the Securities from a Substitute Rating Agency for
purposes of determining any increase or decrease in the interest rate on this Security pursuant to the tables set forth in this Section 2,
(ii) such Substitute Rating Agency shall be substituted for the last Interest Rate Rating Agency to provide a rating on the Securities
but which has since ceased to provide such rating, (iii) the relative ratings scale used by such Substitute Rating Agency to assign
ratings to senior unsecured debt shall be determined in good faith by an independent investment banking institution of national standing
appointed by the Company and, for purposes of determining the applicable ratings included in the applicable table in this Section 2
with respect to such Substitute Rating Agency, such ratings shall be deemed to be the equivalent ratings used by Fitch or S&P, as
applicable, in such table, and (iv) the interest rate payable on this Security shall increase or decrease, as the case may be, such
that the interest rate payable equals the Original Interest Rate plus the appropriate percentage, if any, set forth opposite the rating
from such Substitute Rating Agency in the applicable table in this Section 2 (taking into account the provisions of clause (iii) in
this paragraph (1)) (plus any applicable percentage resulting from a decreased rating by the other Interest Rate Rating Agency);

 

    A-5

     

    

 

(2)            for
so long as only one Interest Rate Rating Agency provides a rating on the Securities, any increase or decrease in the interest rate payable
on this Security necessitated by a reduction or increase in the rating by that Interest Rate Rating Agency shall be twice the applicable
percentage set forth in the applicable table set forth in this Section 2;

 

(3)            if
both Interest Rate Rating Agencies cease to provide a rating of the Securities for any reason, and no Substitute Rating Agency has provided
a rating on the Securities, the interest rate shall increase to, or remain at, as the case may be, 2.00% per annum above the Original
Interest Rate prior to any such adjustment;

 

(4)            if
Fitch or S&P ceases to rate the Securities or make a rating of the Securities publicly available for reasons within Parent’s
control, the Company shall not be entitled to obtain a rating from a Substitute Rating Agency and the increase or decrease in the interest
rate on this Security shall be determined in the manner described in this Section 2 as if either only one or no Interest Rate Rating
Agency provides a rating on the Securities, as the case may be;

 

(5)            each
interest rate adjustment required by any decrease or increase in a rating as set forth in this Section 2, whether occasioned by the
action of Fitch or S&P (or, in either case, any Substitute Rating Agency), shall be made independently of (and in addition to) any
and all other interest rate adjustments occasioned by the action of the other Interest Rate Rating Agency;

 

(6)            in
no event shall (i) the interest rate on this Security be reduced to below the Original Interest Rate prior to any such adjustment
or (ii) the total increase in the interest rates on this Security pursuant to this Section 2 exceed 2.00% above the Original
Interest Rate; and

 

(7)            subject
to paragraphs (3) and (4) of this Section 2, no adjustment in the interest rate on this Security shall be made solely as
a result of an Interest Rate Rating Agency ceasing to provide a rating of the Securities.

 

If at any time the interest
rate on this Security has been adjusted upward and either of the Interest Rate Rating Agencies subsequently increases its rating of the
Securities, the interest rate on this Security shall again be adjusted (and decreased, if appropriate) such that the interest rate on
this Security equals the Original Interest Rate prior to any such adjustment plus (if applicable) an amount equal to the sum of the percentages
per annum set forth opposite the ratings in the tables set forth in this Section 2 with respect to the ratings assigned to the Securities
(or deemed assigned) at that time, all calculated in accordance with the rules of interpretation set forth in this Section 2.
If Fitch, S&P or any Substitute Rating Agency subsequently increases its rating on the Securities to “BBB-” (or its equivalent
if with respect to any Substitute Rating Agency) or higher, the interest rate on this Security shall be decreased to the Original Interest
Rate prior to any adjustments made pursuant to this Section 2.

 

    A-6

     

    

 

Any increase or decrease in
the interest rate shall take effect from the first day of the interest period during which a rating change occurs requiring an adjustment
in the interest rate. If either Interest Rate Rating Agency changes its rating of the Securities more than once during any particular
interest period, the last such change by such Interest Rate Rating Agency to occur shall control in the event of a conflict for purposes
of any increase or decrease in the interest rate.

 

The interest rate shall permanently
cease to be subject to any adjustment (notwithstanding any subsequent decrease in the ratings by either Interest Rate Rating Agency) if
the Securities become rated “BBB+” or higher by Fitch or S&P (or their equivalent if with respect to any Substitute Rating
Agency), in each case with a stable or positive outlook.

 

If the interest rate payable
on this Security is increased as set forth in this Section 2, the term “interest” shall be deemed to include any such
additional interest unless the context otherwise requires.

 

3.            Method
of Payment. The Company shall pay interest on this Security (except defaulted interest), if any, to the persons in whose name such
Security is registered at the close of business on the regular record date referred to on the facing page of this Security for such
interest installment. In the event that this Security or a portion hereof is called for redemption and the Redemption Date is subsequent
to a regular record date with respect to any Interest Payment Date and prior to such Interest Payment Date, interest on this Security
shall be paid upon presentation and surrender of this Security as provided in the Indenture. The principal of and the interest on this
Security shall be payable in the coin or currency of the United States of America that at the time is legal tender for public and private
debt, at the office or agency of the Company maintained for that purpose in accordance with the Indenture.

 

4.            Paying
Agent and Registrar. Initially, U.S. Bank National Association, the Trustee, shall act as paying agent and Security Registrar. The
Company may change or appoint any paying agent or Security Registrar without notice to any Securityholder. The Guarantor, the Company
or any of their Subsidiaries may act in any such capacity.

 

5.            Indenture.
The terms of this Security include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture
Act of 1939 (the “TIA”) as in effect on the date the Indenture is qualified. This Security is subject to all such terms,
and Securityholders are referred to the Indenture and the TIA for a statement of such terms. These Securities are unsecured general obligations
of the Company and constitute the series designated on the face hereof as the “2.750% Senior Notes due 2031”, initially limited
to $300,000,000 in aggregate principal amount.

 

    A-7

     

    

 

The Company shall furnish

Counsel, Telecopy No. (763) 204-7951.

 

6.            Optional
Redemption. This Security is subject to redemption at the option of the Company on any date prior to the maturity date, in whole or
from time to time in part, in principal amounts of $2,000 or any integral multiple of $1,000 above that amount (provided that any
remaining principal amount thereof shall be at least the minimum authorized denomination thereof), on written notice given to each Securityholder
thereof at its address shown in the Security Register for this Security (or, as to Securities represented by a Global Security, electronically
in accordance with the Depositary’s Applicable Procedures) not less than 15 days nor more than 90 days prior to the date fixed for
redemption in such notice (the “Redemption Date”); provided that redemption notices may be provided more than 90 days
prior to the Redemption Date if the notice is issued in connection with the defeasance of the Securities or the satisfaction and discharge
of the Securities. The Securities shall be redeemable at a redemption price equal to (x) if the Redemption Date is prior to August 15,
2031 (the “Par Call Date”), the greater of (i) 100% of the principal amount of such Securities to be redeemed
and (ii) the sum of the present values of the remaining scheduled payments of principal and interest thereon that would be due (if
such Securities to be redeemed matured on the Par Call Date) from the Redemption Date to the Par Call Date (exclusive of any accrued interest)
discounted to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate
plus 20 basis points; or (y) if the Redemption Date is on or after the Par Call Date, 100% of the principal amount of the Securities
to be redeemed, plus, in the case of each of (x) and (y), any interest accrued but not paid to the date of redemption (subject to
the right of Holders on the relevant record date to receive interest due on, but not including, the relevant Interest Payment Date).

 

Any
notice of redemption may, at the Company’s discretion, be subject to one or more conditions precedent, including completion
of a refinancing transaction or other corporate transaction that is pending (such as an equity or equity-linked offering, an incurrence
of indebtedness or an acquisition or other strategic transaction involving a change of control in the Company or another entity). In addition,
if such redemption or notice is subject to satisfaction of one or more conditions precedent, the Company may, in its discretion, delay
the Redemption Date until such time as any or all such conditions shall be satisfied or waived, 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 or waived by the Redemption Date, or
by the Redemption Date so delayed.

 

This Security is also subject
to redemption to the extent provided in Section 14.01 of the Base Indenture.

 

If the giving of the notice
of redemption is completed as provided in the Indenture, interest on such Securities or portions of Securities shall cease to accrue on
and after the Redemption Date, unless the Company shall default in the payment of any such redemption price and accrued interest with
respect to any such Security or portion thereof.

 

    A-8

     

    

 

Except as otherwise expressly
provided herein or in the Fourth Supplemental Indenture, the Company shall not be required to make mandatory redemption or sinking fund
payments with respect to this Security.

 

“Comparable Redemption
Treasury Issue” means the United States Treasury security selected by an Independent Investment Banker as having a maturity
comparable to the remaining term of such Securities to be redeemed (assuming, for this purpose, that such Securities matured on the Par
Call Date) that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues
of corporate debt securities of comparable maturity to the remaining term of such Securities.

 

“Comparable Redemption
Treasury Price”, with respect to any Redemption Date, means (i) the average of the Redemption Reference Treasury Dealer
Quotations for such Redemption Date, after excluding the highest and lowest such Redemption Reference Treasury Dealer Quotations (unless
there is more than one highest or lowest quotation, in which case only one such highest and/or lowest quotation shall be excluded), or
(ii) if the Independent Investment Banker obtains fewer than four such Redemption Reference Treasury Dealer Quotations, the average
of all such Redemption Reference Treasury Dealer Quotations.

 

“Independent Investment
Banker” means one of the Redemption Reference Treasury Dealers appointed by the Company.

 

“Redemption Reference
Treasury Dealers” means four primary U.S. government securities dealers in the United States selected by the Company.

 

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

 

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

7.            Change
of Control Triggering Event. If a Change of Control Triggering Event occurs with respect to this Security, unless the Company has
exercised its option to redeem this Security, it shall be required to make an offer to the holder of this Security to repurchase, at such
holder's election, all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of such holder’s Security
on the terms set forth in the Indenture, in cash equal to 101% of the aggregate principal amount of this Security to be repurchased, plus
accrued and unpaid interest, if any, on such Security to, but excluding, the date of repurchase (a “Change of Control Payment”).
Within 30 days following any Change of Control Triggering Event with respect to this Security, or at the Company’s option, prior
to any Change of Control with respect to this Security, but after public announcement of the transaction that constitutes or may constitute
the Change of Control, a notice shall be sent to the Trustee and to each Securityholder describing in reasonable detail the transaction
that constitutes or may constitute the Change of Control Triggering Event and offering to repurchase this Security on the date specified
in the notice, which date shall, except as described in the immediately following sentence, be no earlier than 30 days and no later than
60 days from the date such notice is sent (or in the case of a notice prior to the consummation of the Change of Control Triggering Event,
no earlier than 30 days nor later than 60 days from the Change of Control Triggering Event) other than as may be required by law (a “Change
of Control Payment Date”). The notice shall, if sent prior to the date of consummation of the Change of Control, state that

will be made on the next Business Day as if it were made on the date such payment was due, and no interest will accrue on the amounts
so payable for the period from and after such date to the next Business Day.

duly executed if so required by the Company or the Security Registrar) at the office of the Security Registrar or at the office of any
transfer agent designated by the Company for such purpose. No service charge shall be made for any registration of transfer or exchange,
but a Securityholder may be required to pay any applicable taxes or other governmental charges. If the Securities are to be redeemed,
the Company shall not be required to: (i) issue, register the transfer of, or exchange any Security during a period beginning at

series and ending at the close of business on the day such notice of redemption is sent; (ii) register the transfer of or exchange
any Security of any series or portions thereof selected for redemption, in whole or in part, except the unredeemed portion of any such

9.            Persons
Deemed Owners. The registered Securityholder may be treated as its owner for all purposes.

 

10.          Repayment
to the Guarantor or the Company. Any funds or Governmental Obligations deposited with any paying agent or the Trustee, or then held
by the Guarantor or the Company, in trust for payment of principal of, premium, if any, or interest on the Securities that are not applied
but remain unclaimed by the Securityholders for at least one year after the date upon which the principal of, premium, if any, or interest
on such Securities shall have respectively become due and payable, shall be repaid to the Guarantor or the Company, as applicable, or
(if then held by the Guarantor or the Company) shall be discharged from such trust. After return to the Company or the Guarantor, Securityholders
entitled to the money or securities must look to the Company or the Guarantor, as applicable, for payment as unsecured general creditors.

 

11.          Amendments,
Supplements and Waivers. The Base Indenture contains provisions permitting the Company, the Guarantor and the Trustee, with the consent
of the holders of not less than a majority in aggregate principal amount of the securities of each series at the time Outstanding affected
by such supplemental indenture or indentures to enter into supplemental indentures for the purpose of adding, changing or eliminating
any provisions of the Base Indenture or any supplemental indenture or of modifying in any manner not covered elsewhere in the Base Indenture
the rights of the holders of the securities of such series; provided, however, that no such supplemental indenture, without
the consent of the holders of each security then Outstanding and affected thereby, shall: (i) extend a fixed maturity of or any installment
of principal of any securities of any series or reduce the principal amount thereof, or reduce the amount of principal of any original
issue discount security that would be due and payable upon declaration of acceleration of the maturity thereof; (ii) reduce the rate
of or extend the time for payment of interest on any security of any series; (iii) reduce the premium payable upon the redemption
of any security; (iv) make any security payable in Currency other than that stated in the security; (v) impair the right to
institute suit for the enforcement of any payment on or after the fixed maturity thereof (or in the case of redemption, on or after the
redemption date); or (vi) reduce the aforesaid percentage of securities, the holders of which are required to consent to any such
supplemental indenture or indentures.

 

The Base Indenture also contains
provisions permitting the holders of not less than a majority in aggregate principal amount of the Outstanding securities of each series
affected thereby, on behalf of all of the holders of the securities of such series, to waive any past default under the Base Indenture,
and its consequences, except a default in the payment of the principal of, premium, if any, or interest on, any of the securities of such
series as and when the same shall become due by the terms of such securities.

 

Any such consent or waiver
by the registered Securityholder shall be conclusive and binding upon such Securityholder and upon all future Securityholders and owners
of this Security and of any Security issued in exchange for this Security or in place hereof (whether by registration of transfer or otherwise),
irrespective of whether or not any notation of such consent or waiver is made upon this Security.

 

    A-11

     

    

 

12.          Defaults
and Remedies. If an Event of Default with respect to the securities of a series issued pursuant to the Base Indenture occurs and is
continuing, the Trustee at the written request of the holders or the holders of at least 25% in aggregate principal amount of the securities
of such series then Outstanding, by notice in writing to the Company and the Guarantor (and to the Trustee if notice is given by such
holders), may declare the unpaid principal of, premium, if any, and accrued interest, if any, due and payable immediately. Subject to
the terms of the Indenture, if an Event of Default under the Indenture shall occur and be continuing, the Trustee shall be under no obligation
to exercise any of its rights or powers under the Indenture at the request or direction of any of the holders, unless such holders have
offered the Trustee indemnity satisfactory to it. Upon satisfaction of certain conditions set forth in the Indenture, the holders of a
majority in principal amount of the Outstanding securities of a series issued pursuant to the Base Indenture shall have the right to direct
the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred
on the Trustee, with respect to the securities of such series.

 

13.          Trustee,
Paying Agent and Security Registrar May Hold Securities. The Trustee, subject to certain limitations imposed by the TIA, or any
paying agent or Security Registrar, in its individual or any other capacity, may become the owner or pledgee of Securities with the same
rights it would have if it were not Trustee, paying agent or Security Registrar.

 

14.          No
Recourse Against Others. No recourse under or upon any obligation, covenant or agreement of the Indenture, or of any Security, or
for any claim based thereon or otherwise in respect hereof or thereof, shall be had against any incorporator, stockholder, officer or
director, past, present or future as such, of the Guarantor or the Company or of any predecessor or successor Person, either directly
or through the Guarantor or the Company or any such predecessor or successor Person, whether by virtue of any constitution, statute or
rule of law, or by the enforcement of any assessment or penalty or otherwise; it being expressly understood that the Indenture and
the obligations issued hereunder and thereunder are solely corporate obligations, and that no such personal liability whatever shall attach
to, or is or shall be incurred by, the incorporators, organizers, shareholders, partners, members, officers, directors, managers or agents
as such, of the Guarantor or the Company or of any predecessor or successor Person, or any of them, because of the creation of the indebtedness
authorized by the Indenture, or under or by reason of the obligations, covenants or agreements contained in the Indenture or in the Securities
or implied therefrom; and that any and all such personal liability of every name and nature, either at common law or in equity or by constitution
or statute, of, and any and all such rights and claims against, every such incorporator, organizer, shareholder, partner, member, officer,
director, manager or agent as such, because of the creation of the indebtedness authorized by the Indenture, or under or by reason of
the obligations, covenants or agreements contained in the Indenture or in the Securities or implied therefrom, are hereby expressly waived
and released as a condition of, and as a consideration for, the acceptance of the Securities.

        17.      Corporate Authority. Landlord and Tenant represent and warrant to the other that each has the power and authority to enter
            into this Amendment and that the person duly executing this Amendment on behalf of each party has the requisite power and authority to do so.

      

       

      
        18.      Entire Agreement. The

            matter. No representations, warranties, undertakings or promises, whether oral, implied, written, or otherwise, have been made by any party to any other party unless expressly stated in the above-referenced documents, or unless mutually agreed

      19.      Effectiveness. The parties agree that the submission of a draft or copy of this Amendment for review or
            signature by a party is not intended, nor will it constitute or be deemed, by either party to be an offer to enter into a legally binding agreement with respect to the subject matter hereof and may not be relied on for any legal or equitable rights or obligations. Any draft or document submitted by Landlord or its agents to Tenant will not constitute a reservation of or option or offer in favor of Tenant. The parties
            will be legally bound with respect to the subject matter hereof pursuant to the terms of this Amendment only if, as and when all the parties have executed and delivered this Amendment to each other. Before the complete execution and delivery of
            this Amendment by all parties, each party will be free to negotiate the form and terms of this Amendment in a manner acceptable to that party in its sole and absolute discretion. The parties acknowledge and agree that the execution and delivery
            by one party before the execution and delivery of this Amendment by the other party will be of no force and effect and will in no way prejudice the party that executed this Amendment or the party that has not executed this Amendment.
