of the First Lien Intercreditor Agreement or in the event a Market Intercreditor Agreement has been entered into after the Completion
Date, an intercreditor or subordination agreement or arrangement the terms of which are, taken as a whole, not materially less favorable

SECTION 1.03.     Certain
Interpretative Provisions.

 

(a)            For
purposes of all Financial Definitions and calculations in this Indenture, (i) there shall be excluded for any period the effects
of purchase accounting (including the effects of such adjustments pushed down to UK Holdco and the Restricted Subsidiaries) in component
amounts required or permitted by GAAP and related authoritative pronouncements (including the effects of such adjustments pushed down
to UK Holdco and the Restricted Subsidiaries), as a result of the Transactions, any acquisition consummated prior to the Completion Date,
any acquisitions permitted under this Indenture, or the amortization or write-off of any amounts thereof and (ii) effect shall not
be given to (A) any election under Accounting Standards Codification 825-10-25 (previously referred to as Statement of Financial
Accounting Standards 159) (or any other Accounting Standards Codification, International Accounting Standard or Financial Accounting
Standard having a similar result or effect) to value any Indebtedness or other liabilities of UK Holdco or any Subsidiary at “fair
value,” as defined therein, (B) any treatment of Indebtedness in respect of convertible debt instruments under Accounting Standards
Codification 470-20 (or any other Accounting Standards Codification, International Accounting Standard or Financial Accounting Standard
having a similar result or effect) to value any such Indebtedness in a reduced or bifurcated manner as described therein, and such Indebtedness
shall at all times be valued at the full stated principal amount thereof or (C) the application of Accounting Standards Codification
480, 815, 805 and 718 (to the extent these pronouncements under Accounting Standards Codification 718 result in recording an equity award
as a liability on the consolidated balance sheet of UK Holdco and its Restricted Subsidiaries in the circumstance where, but for the application
of the pronouncements, such award would have been classified as equity). Any calculation or determination in this Indenture that requires
the application of GAAP across multiple quarters need not be calculated or determined using the same accounting standard for each constituent
quarter.

 

(b)            Notwithstanding
anything to the contrary contained in this Indenture or in the definition of “Capitalized Lease Obligation”, unless UK Holdco
elects otherwise, all obligations of any Person that are or would have been treated as operating leases for purposes of GAAP prior to
the issuance by the Financial Accounting Standards Board on February 25, 2016 of an Accounting Standards Update (the “ASU”)
shall continue to be accounted for as operating leases (and not be treated as financing or capital lease obligations or Indebtedness)
for purposes of all Financial Definitions, calculations and deliverables under this Indenture (including the calculation of Consolidated
Net Income and EBITDA) (whether or not such operating lease obligations were in effect on such date) notwithstanding the fact that such
obligations are required in accordance with the ASU or any other change in accounting treatment or otherwise (on a prospective or retroactive
basis or otherwise) to be treated as or to be re-characterized as financing or capital lease obligations or otherwise accounted for as
liabilities in financial statements. Interest on a Capitalized Lease Obligation shall be deemed to accrue at an interest rate reasonably
determined by a responsible financial or accounting officer of UK Holdco to be the rate of interest implicit in such Capitalized Lease
Obligation in accordance with GAAP.

(c)            Interest
on Indebtedness that may optionally be determined at an interest rate based upon a factor of a prime or similar rate, a eurocurrency interbank
offered rate, or other rate, shall be deemed to have been based upon the rate actually chosen, or, if none, then based upon such optional
rate chosen as UK Holdco may designate.

 

(d)            For
purposes of covenant compliance, the amount of any Investment shall be the amount actually invested, without adjustment for subsequent
increases or decreases in the value of such Investment but giving effect to any returns or distributions of capital or repayment of principal
actually received in cash by such Person with respect thereto.

SECTION 1.05.     Limited
Condition Transactions and Other Compliance Measurements.

 

(a)            Notwithstanding
anything to the contrary in this Indenture (including in connection with any calculation that is made on a Pro Forma Basis), in connection
with any action being taken in connection with a Limited Condition Transaction, for purposes of

 

(i)            determining
compliance with any provision of this Indenture which (i) requires the calculation of any financial ratio or test (including the
Consolidated First Lien Debt Ratio, Consolidated Secured Debt Ratio, Consolidated Total Debt Ratio and Fixed Charge Coverage Ratio) and/or
(ii) requires the absence of any Default or Event of Default (or any type of Default or Event of Default); or

 

(ii)           determining
compliance with any basket or other condition set forth in this Indenture (including baskets measured as a percentage of LTM EBITDA);

 

in each case, at the option of UK Holdco (UK Holdco’s
election to exercise such option in connection with any Limited Condition Transaction, an “LCT Election”), the date of determination
of whether any such action is permitted under this Indenture shall be deemed to be (A) in the case of any acquisition or other Investment
(including by way of merger, amalgamation or consolidation), any Asset Sale or any assumption or Incurrence of Indebtedness or issuance
of Preferred Stock or Disqualified Stock, or any transaction relating thereto, the date (or on the basis of the financial statements for
the most recently ended reference period) of entry into a binding letter of intent or the definitive agreements for such Limited Condition
Transaction (or, solely in connection with an acquisition (including by way of merger, amalgamation or consolidation) to which the United
Kingdom City Code on Takeovers and Mergers applies, the date on which a “Rule 2.7 Announcement” of a firm intention to
make an offer is made); (B) in the case of any repayment, repurchase or refinancing of Indebtedness, the date that the irrevocable
notice, which may be conditional, of such repayment, repurchase or refinancing of Indebtedness is given to the Holders of such Indebtedness;
or (C) in the case of any other Restricted Payment, at the time (or on the basis of the financial statements for the most recently
ended reference period) of the declaration of such Restricted Payment (the applicable date determined pursuant to clause (A), (B) or
(C), the “LCT Test Date”), and if, after giving effect to the Limited Condition Transaction and the other transactions to
be entered into in connection therewith (including any Incurrence of Indebtedness and the use of proceeds thereof) and, at the election
of UK Holdco, any other Limited Condition Transaction that has not been consummated but with respect to which UK Holdco has made an LCT
Election, on a Pro Forma Basis as if they had occurred at the beginning of the most recently completed reference period ending prior to
the LCT Test Date, UK Holdco or the applicable Restricted Subsidiary would have been permitted to take such action on the relevant LCT
Test Date in compliance with such ratio, test, basket or condition, such ratio, test, basket or condition shall be deemed to have been
complied with. For the avoidance of doubt, if UK Holdco has made an LCT Election and any of the ratios, tests, baskets or conditions for
which compliance was determined or tested as of the LCT Test Date are exceeded as a result of fluctuations in any such ratio, test, basket
or condition, including due to fluctuations in LTM EBITDA at or prior to the consummation of the relevant transaction or action, such
baskets, tests, ratios and conditions will not be deemed to have been exceeded as a result of such fluctuations.

 

    -52- 

     

    

 

(b)            In
addition, for purposes of determining the permissibility of any action, change, transaction or event that requires a calculation of any
financial ratio or financial test and/or the amount of EBITDA or Consolidated Net Income, such financial ratio, financial test or amount
shall, subject to Section 1.05(a), be calculated at the time such action is taken, such change is made, such transaction is consummated
or such event occurs, as the case may be, and no Default or Event of Default shall be deemed to have occurred solely as a result of a
change in such financial ratio, financial test or amount occurring after the time such action is taken, such change is made, such transaction
is consummated or such event occurs, as the case may be.

 

(c)            Notwithstanding
anything to the contrary in this Indenture, unless UK Holdco otherwise notifies the Trustee, with respect to any amount Incurred or transaction
entered into (or consummated) in reliance on a provision of this Indenture that does not require compliance with a financial ratio or
financial test (any such amount, including any amount drawn under any revolving credit facility and any cap expressed as a percentage
of Consolidated Net Income or EBITDA, a “Fixed Amount”) substantially concurrently with any amount Incurred or transaction
entered into (or consummated) in reliance on a provision of this Indenture that requires compliance with a financial ratio or financial
test (any such amount, an “Incurrence-Based Amount”), it is understood and agreed that (i) the Incurrence of the
Incurrence-Based Amount shall be calculated first without giving effect to any Fixed Amount but giving full pro forma effect to the use
of proceeds of such Fixed Amount and the related transactions and (ii) the Incurrence of the Fixed Amount shall be calculated thereafter.
Unless UK Holdco elects otherwise, UK Holdco shall be deemed to have used amounts under an Incurrence-Based Amount then available to UK
Holdco prior to utilization of any amount under a Fixed Amount then available to UK Holdco.

 

(d)            Subject
to Sections 1.05(a), (b) and (c), all financial ratios and tests and the amount of Consolidated Net Income and EBITDA contained in
this Indenture that are calculated with respect to any reference period shall be calculated with respect to such reference period on a
Pro Forma Basis.

 

(e)            For
purposes of determining compliance with the covenants set forth under‎ Section 4.03 or Section 4.11 or the definition
of “Permitted Liens”, if any Indebtedness, Preferred Stock, Disqualified Stock or Lien is created or Incurred in reliance
on a basket measured by reference to a percentage of EBITDA, and any refinancing or replacement thereof would cause the percentage of
EBITDA to be exceeded if calculated based on the EBITDA on the date of such refinancing or replacement, such percentage of EBITDA will
be deemed not to be exceeded so long as the principal amount of such refinancing or replacement Indebtedness, Preferred Stock, Disqualified
Stock or other obligation does not exceed an amount sufficient to repay the principal amount of such Indebtedness, Preferred Stock, Disqualified
Stock or other obligation being refinanced or replaced, except by an amount equal to (x) the amount necessary to pay accrued and
unpaid interest, fees, underwriting discounts and expenses, including any premium and defeasance costs Incurred in connection with such
refinancing or replacement and (y) additional amounts permitted to be Incurred pursuant to Section 4.03.

THE SECURITIES

 

SECTION 2.01.     Amount
of Securities; Issuable in Series. The aggregate principal amount of Original Securities which may be authenticated and delivered
under this Indenture on the Issue Date is $1,000,000,000. The Securities may be issued in one or more series. All Securities of any one
series shall be substantially identical except as to denomination.

 

    -53- 

     

    

 

The Issuer may from time to time after the Issue
Date issue Additional Securities under this Indenture in an unlimited principal amount, so long as (i) the Incurrence of the Indebtedness
represented by such Additional Securities is at such time permitted by Section 4.03 and Section 4.11 and (ii) such Additional
Securities are issued in compliance with the other applicable provisions of this Indenture. With respect to any Additional Securities
issued after the Issue Date (except for Securities authenticated and delivered upon registration of transfer of, or in exchange for, or
in lieu of, other Securities pursuant to Sections 2.07, 2.08, 2.09, 2.10, 3.08, 3.09(e), 4.08(c) or the Appendix), there
shall be (a) established in or pursuant to a resolution of the Board of Directors of the Issuer and (b)(i) set forth or determined
in the manner provided in an Officer’s Certificate or (ii) established in one or more supplemental indentures hereto, prior
to the issuance of such Additional Securities:

 

(1)            whether
such Additional Securities shall be issued as part of a new or existing series of Securities and the title of such Additional Securities
(which shall distinguish the Additional Securities of the series from Securities of any other series);

 

(2)            the
aggregate principal amount of such Additional Securities which may be authenticated and delivered under this Indenture;

 

(3)            the
issue price and issuance date of such Additional Securities, including the date from which interest on such Additional Securities shall
accrue; and

 

(4)            if
applicable, that such Additional Securities shall be issuable in whole or in part in the form of one or more Global Securities and, in
such case, the respective depositaries for such Global Securities, the form of any legend or legends which shall be borne by such Global
Securities in addition to or in lieu of those set forth in Exhibit A hereto and any circumstances in addition to or in lieu
of those set forth in Section 2.2 of the Appendix in which any such Global Security may be exchanged in whole or in part for
Additional Securities registered, or any transfer of such Global Security in whole or in part may be registered, in the name or names
of Persons other than the depositary for such Global Security or a nominee thereof.

 

If any of the terms of any Additional Securities
are established by action taken pursuant to a resolution of the Board of Directors of the Issuer, a copy of an appropriate record of such
action shall be certified by the Secretary or any Assistant Secretary of the Issuer and delivered to the Trustee at or prior to the delivery
of the Officer’s Certificate or the supplemental indenture hereto setting forth the terms of the Additional Securities.

 

Additionally, the Trustee shall receive an Officer’s
Certificate in accordance with Section 12.04, and the Trustee shall receive an Opinion of Counsel which shall state:

 

(1)            that
the form of such Additional Securities has been established by a supplemental indenture or by or pursuant to a resolution of the Board
of Directors in conformity with the provisions of this Indenture;

 

(2)            that
the terms of such Additional Securities have been established in conformity with the other provisions of this Indenture;

 

(3)            that
such Additional Securities, when authenticated and delivered by the Trustee or its Authenticating Agent and issued by the Issuer in the
manner and subject to any conditions specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the
Issuer, enforceable in accordance with their terms, subject to bankruptcy, insolvency, reorganization and other laws of general applicability
relating to or affecting the enforcement of creditors' rights and to general equity principles; and

 

    -54- 

     

    

 

(4)            that
all covenants and conditions precedent under this Indenture with respect to the issuance, authentication and delivery of such Additional
Securities have been complied with.

 

SECTION 2.02.     Form and
Dating. Provisions relating to the Securities are set forth in the Appendix, which is hereby incorporated in and expressly
made a part of this Indenture. The Original Securities and the Trustee’s certificate of authentication, and any Additional Securities
(if issued as Transfer Restricted Definitive Securities) and the Trustee’s certificate of authentication, shall each be substantially
in the form of Exhibit A hereto, which is hereby incorporated in and expressly made a part of this Indenture. The Securities
may have notations, legends or endorsements required by law, stock exchange rule, agreements to which the Issuer or any Guarantor is
subject, if any, or usage (provided that any such notation, legend or endorsement is in a form acceptable to the Issuer). Each
Security shall be dated the date of its authentication. The Securities shall be issuable only in fully registered form without coupons
and only in minimum denominations of $2,000 and any integral multiples of $1,000 in excess thereof.

 

SECTION 2.03.     Execution
and Authentication. The Trustee or its Authenticating Agent shall authenticate and make available for delivery upon a written order
of the Issuer signed by one or more officers, directors or authorized signatories of the Issuer (an “Authentication Order”)
(a) Original Securities for original issue on the date hereof of $1,000,000,000 in aggregate principal amount of 3.875% Senior Secured
Notes due 2028 and (b) subject to the terms of this Indenture, Additional Securities in an aggregate principal amount to be determined
at the time of issuance and specified therein. Such Authentication Order shall specify the amount of the Securities to be authenticated
and the date on which the original issue of Securities is to be authenticated. Notwithstanding anything to the contrary in this Indenture
or the Appendix, any issuance of Additional Securities after the Issue Date shall be in a minimum principal amount of $2,000 and
any integral multiples of $1,000 in excess thereof whether such Additional Securities are of the same or a different series than the
Original Securities. Prior to the authentication of the Original Securities, the Trustee shall receive an Officer’s Certificate
in accordance with Section 12.04.

 

One or more officers, directors or authorized signatories
of the Issuer shall sign the Securities for the Issuer by manual, facsimile or other electronic signature.

 

If an officer, director or authorized signatory whose
signature is on a Security no longer holds that office at the time the Trustee or its Authenticating Agent authenticates the Security,
the Security shall be valid nevertheless.

 

A Security shall not be valid until an authorized
signatory of the Trustee or its Authenticating Agent manually signs the certificate of authentication on the Security. The signature shall
be conclusive evidence that the Security has been authenticated under this Indenture.

 

The Trustee may appoint one or more authenticating
agents (each an “Authenticating Agent”) reasonably acceptable to the Issuer to authenticate the Securities. Any such
appointment shall be evidenced by an instrument signed by a Trust Officer, a copy of which shall be furnished to the Issuer. Unless limited
by the terms of such appointment, an authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in
this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as
any Registrar, Paying Agent or agent for service of notices and demands.

 

    -55- 

     

    

 

 

SECTION 2.04.        Registrar
and Paying Agent.

 

(a)            The
Issuer shall maintain (i) an office or agency where Securities may be presented for registration of transfer or for exchange (the
 “Registrar”) and (ii) an office or agency in the United States where Securities may be presented for payment
(the “Paying Agent”). The Registrar shall keep a register of the Securities and of their transfer and exchange. The
Issuer may have one or more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrars.
The term “Paying Agent” includes the Paying Agent and any additional paying agents. The Issuer initially appoints the Trustee
as (i) Registrar and Paying Agent in connection with the Securities and (ii) the Securities Custodian with respect to the Global
Securities.

 

Upon written request from the Issuer or each time
the register of Holders is amended, the Registrar shall provide the Issuer with a copy of the register of Holders.

 

(b)            The
Issuer shall enter into an appropriate agency agreement with any Registrar or Paying Agent not a party to this Indenture. The agreement
shall implement the provisions of this Indenture that relate to such agent. The Issuer shall notify the Trustee in writing of the name
and address of any such agent. If the Issuer fails to maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be
entitled to appropriate compensation therefor pursuant to Section 7.06. The Issuer or any of its domestically organized Wholly Owned
Subsidiaries may act as Paying Agent or Registrar.

 

(c)            The
Issuer may remove any Registrar or Paying Agent upon written notice to such Registrar or Paying Agent and to the Trustee; provided,
however, that no such removal shall become effective until (i) if applicable, acceptance of an appointment by a successor
as evidenced by an appropriate agreement entered into by the Issuer and such successor Registrar or Paying Agent, as the case may be,
and delivered to the Trustee or (ii) written notification to the Trustee that the Trustee shall serve, to the extent it determines
that it is able, as Registrar or Paying Agent until the appointment of a successor in accordance with clause (i) above.

 

SECTION 2.05.        Paying
Agent to Hold Money in Trust. On or prior to 10:00 a.m. (New York City time) on each due date of the principal of and interest
on any Security, the Issuer shall deposit with the Paying Agent (or if the Issuer or a domestically organized Wholly Owned Subsidiary
is acting as Paying Agent, segregate and hold for the benefit of the Persons entitled thereto) a sum sufficient to pay such principal
and interest when so becoming due. The Issuer shall require each Paying Agent (other than the Trustee) to agree in writing that a Paying
Agent shall hold in trust for the benefit of Holders and the Trustee all money held by a Paying Agent for the payment of principal of
and interest on the Securities, and shall notify the Trustee in writing of any default by the Issuer in making any such payment. If the
Issuer or a domestically organized Wholly Owned Subsidiary of the Issuer acts as Paying Agent, it shall segregate the money held by it
as Paying Agent and hold it for the benefit of the Persons entitled thereto. The Issuer at any time may require a Paying Agent to pay
all money held by it to the Trustee and to account for any funds disbursed by such Paying Agent. During the continuance of a Default
under this Indenture, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. Upon any bankruptcy or reorganization
proceedings relating to the Issuer, the Trustee will serve as Paying Agent. Upon complying with this Section 2.05, a Paying Agent
shall have no further liability for the money delivered to the Trustee. For the avoidance of doubt, a Paying Agent and the Trustee shall
be held harmless and have no liability with respect to payments and disbursements to be made by a Paying Agent and the Trustee until
they have confirmed receipt of funds sufficient to make the relevant payment. No money held by an Agent needs to be segregated except
as is required by law.

 

    -56-

    

    

 

SECTION 2.06.        Holder
Lists. The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names
and addresses of Holders. If the Trustee is not the Registrar, the Issuer shall furnish, or cause the Registrar to furnish, to the Trustee,
in writing at least five Business Days before each interest payment date and at such other times as the Trustee may request in writing,
a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Holders.

 

SECTION 2.07.        Transfer
and Exchange. The Securities shall be issued in registered form and shall be transferable only upon the surrender of a Security for
registration of transfer and in compliance with the Appendix. When a Security is presented to the Registrar with a request to
register a transfer, the Registrar shall register the transfer as requested if its requirements therefor are met. When Securities are
presented to the Registrar with a request to exchange them for an equal principal amount of Securities of other denominations, the Registrar
shall make the exchange as requested if the same requirements are met. To permit registration of transfers and exchanges, the Issuer
shall execute and upon receipt of an Authentication Order the Trustee or its Authenticating Agent shall authenticate Securities at the
Registrar’s request. The Issuer may require a Holder to pay a sum sufficient to pay all Taxes, assessments or other governmental
charges in connection with any transfer or exchange pursuant to this Section 2.07. The Issuer shall not be required to make, and
the Registrar need not register, transfers or exchanges of Securities selected for redemption (except, in the case of Securities to be
redeemed in part, the portion thereof not to be redeemed) or of any Securities for a period of 15 days prior to the sending of a notice
of redemption or of any Securities to be redeemed or tendered and not withdrawn in connection with a Change of Control Offer, a Collateral
Asset Sale Offer or an Asset Sale Offer.

 

Prior to the due presentation for registration of
transfer of any Security, the Issuer, the Guarantors, the Trustee, the Paying Agent and the Registrar may deem and treat the Person in
whose name a Security is registered as the absolute owner of such Security for the purpose of receiving payment of principal of and interest,
if any, on such Security and for all other purposes whatsoever, whether or not such Security is overdue, and none of the Issuer, any
Guarantor, the Trustee, a Paying Agent or the Registrar shall be affected by notice to the contrary.

 

Any Holder of a beneficial interest in a Global
Security shall, by acceptance of such beneficial interest, agree that transfers of beneficial interests in such Global Security may be
effected only through a book-entry system maintained by (a) the Holder of such Global Security (or its agent) or (b) any Holder
of a beneficial interest in such Global Security, and that ownership of a beneficial interest in such Global Security shall be required
to be reflected in a book entry.

 

All Securities issued upon any transfer or exchange
pursuant to the terms of this Indenture shall evidence the same debt and shall be entitled to the same benefits under this Indenture
as the Securities surrendered upon such transfer or exchange.

 

The Trustee shall have no obligation or duty to
monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture, the Appendix or under
applicable law with respect to any transfer of any interest in any Security other than to require delivery of such certificates and other
documentation or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture and
the Appendix.

 

Neither the Trustee nor any of its agents shall have
any responsibility or liability for any actions taken or not taken by the depositary with which the Global Security is registered.

 

    -57-

    

    

 

SECTION 2.08.        Replacement
Securities. If a mutilated Security is surrendered to the Registrar or if the Holder of a Security claims that the Security has been
lost, destroyed or wrongfully taken, the Issuer shall issue and the Trustee shall authenticate (upon receipt of an Authentication Order)
a replacement Security if the requirements of Section 8-405 of the Uniform Commercial Code are met, such that the Holder (a) satisfies
the Issuer or the Trustee within a reasonable time after such Holder has notice of such loss, destruction or wrongful taking and the
Registrar does not register a transfer prior to receiving such notification, (b) makes such request to the Issuer or the Trustee
prior to the Security being acquired by a protected purchaser as defined in Section 8-303 of the Uniform Commercial Code (a “protected
purchaser”) and (c) satisfies any other reasonable requirements of the Trustee. Such Holder shall furnish an indemnity
bond sufficient in the judgment of (i) the Trustee to protect the Trustee or (ii) the Issuer, to protect the Issuer, the Trustee,
a Paying Agent and the Registrar, from any loss that any of them may suffer if a Security is replaced. The Issuer and the Trustee may
charge the Holder for the Issuer’s or Trustee’s expenses in replacing a Security (including, without limitation, attorneys’
fees and disbursements in replacing such Security). In the event any such mutilated, lost, destroyed or wrongfully taken Security has
become or is about to become due and payable, the Issuer in its discretion may pay such Security instead of issuing a new Security in
replacement thereof.

 

Every replacement Security is an additional obligation
of the Issuer.

 

The provisions of this Section 2.08 are exclusive
and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, lost,
destroyed or wrongfully taken Securities.

 

SECTION 2.09.        Outstanding
Securities. Securities outstanding at any time are all Securities authenticated by the Trustee or its Authenticating Agent except
for those canceled by it, those delivered to it for cancellation, those paid or replaced pursuant to Section 2.08 and those described
in this Section 2.09 as not outstanding. Subject to Section 12.06, a Security does not cease to be outstanding because the
Issuer or an Affiliate of the Issuer holds the Security.

 

If a Security is replaced pursuant to Section 2.08
(other than a mutilated Security surrendered for replacement), it ceases to be outstanding unless the Trustee and the Issuer receive
proof satisfactory to them that the replaced Security is held by a protected purchaser. A mutilated Security ceases to be outstanding
upon surrender of such Security and replacement thereof pursuant to Section 2.08.

 

If a Paying Agent holds, in accordance with this
Indenture, on a redemption date or maturity date money sufficient to pay all principal and interest payable on that date with respect
to the Securities (or portions thereof) to be redeemed or maturing, as the case may be, and no Paying Agent is prohibited from paying
such money to the Holders on that date pursuant to the terms of this Indenture, then on and after that date such Securities (or portions
thereof) cease to be outstanding and interest on them ceases to accrue.

 

SECTION 2.10.        Temporary
Securities. In the event that Definitive Securities are to be issued under the terms of this Indenture, until such Definitive Securities
are ready for delivery, the Issuer may prepare and the Trustee upon receipt of an Authentication Order shall authenticate temporary Securities.
Temporary Securities shall be substantially in the form of Definitive Securities but may have variations that the Issuer considers appropriate
for temporary Securities. Without unreasonable delay, the Issuer shall prepare and upon receipt of an Authentication Order the Trustee
shall authenticate Definitive Securities and make them available for delivery in exchange for temporary Securities upon surrender of
such temporary Securities at the office or agency of the Issuer, without charge to the Holder. Until such exchange, temporary Securities
shall be entitled to the same rights, benefits and privileges as Definitive Securities.

 

    -58-

    

    

 

SECTION 2.11.        Cancellation.
The Issuer at any time may deliver Securities to the Registrar for cancellation. The Trustee and the Paying Agent shall forward to the
Registrar any Securities surrendered to them for registration of transfer, exchange or payment. The Registrar and no one else shall cancel
all Securities surrendered for registration of transfer, exchange, payment or cancellation and shall dispose of canceled Securities in
accordance with its customary procedures. The Issuer may not issue new Securities to replace Securities it has redeemed, paid or delivered
to the Registrar for cancellation. The Trustee shall not authenticate Securities in place of canceled Securities other than pursuant
to the terms of this Indenture.

 

SECTION 2.12.        Defaulted
Interest. If the Issuer defaults in a payment of interest on the Securities, the Issuer shall pay the defaulted interest then borne
by the Securities (plus interest on such defaulted interest to the extent lawful), in any lawful manner. The Issuer may pay the
defaulted interest to the Persons who are Holders on a subsequent special record date. The Issuer shall fix or cause to be fixed any
such special record date and payment date and shall promptly mail or cause to be mailed to each affected Holder a notice that states
the special record date, the payment date and the amount of defaulted interest to be paid.

 

SECTION 2.13.        CUSIP
Numbers and ISINs. The Issuer in issuing the Securities may use CUSIP numbers and ISINs (if then generally in use) and, if so, the
Trustee shall use CUSIP numbers and ISINs in notices of redemption as a convenience to Holders; provided, however, that
any such notice may state that no representation is made as to the correctness of such numbers, either as printed on the Securities or
as contained in any notice of a redemption, that reliance may be placed only on the other identification numbers printed on the Securities
and that any such redemption shall not be affected by any defect in or omission of such numbers; provided, further, that
if any Additional Securities are not fungible with the Original Securities for U.S. federal income tax purposes, such Additional Securities
will have a separate CUSIP number and ISINs. The Issuer shall promptly advise the Trustee in writing of any change in the CUSIP numbers
and ISINs.

 

SECTION 2.14.        Calculation
of Specified Percentage of Securities. With respect to any matter requiring consent, waiver, approval or other action of the Holders
of a specified percentage of the principal amount of all the Securities, such percentage shall be calculated, on the relevant date of
determination, by dividing (a) the principal amount, as of such date of determination, of Securities, the Holders of which have
so consented by (b) the aggregate principal amount, as of such date of determination, of the Securities then outstanding, in each
case, as determined in accordance with Section 2.09 and Section 12.06 of this Indenture. Any such calculation made pursuant
to this Section 2.14 shall be made by the Issuer and delivered to the Trustee pursuant to an Officer’s Certificate.

 

SECTION 2.15.        Deposit
of Moneys. Subject to actual receipt of such funds as provided by Section 2.05 by the designated Paying Agent and in the case
of the Trustee, subject to the lien provided for in Section 7.06, such Paying Agent shall remit such payment in a timely manner
to the Holders on such day or date, as the case may be, to the Persons and in the manner set forth in Paragraph 2 of the Securities;
provided, however, that no Paying Agent shall be obliged to make a payment until it has received funds sufficient to make such payment.
The Issuer shall promptly notify the Trustee and the respective Paying Agent of its failure to so act.

REDEMPTION

 

SECTION 3.01.        Optional
Redemption.

 

(a)            The
Securities may be redeemed, in whole, or from time to time in part, subject to the conditions and at the redemption prices set forth
in Paragraph 5 of the Form of Security set forth in Exhibit A hereto, which is hereby incorporated by reference and
made a part of this Indenture, together with accrued and unpaid interest to, but not including, the redemption date.

 

(b)            Notwithstanding
anything in this Indenture or the Securities to the contrary, in connection with any tender offer for the Securities, including a Change
of Control Offer, a Collateral Asset Sale Offer or an Asset Sale Offer, if Holders of not less than 90% in aggregate principal amount
of the outstanding Securities validly tender and do not withdraw such Securities in such tender offer and the Issuer, or any third party
making such tender offer in lieu of the Issuer as described herein, purchases all of the Securities validly tendered and not withdrawn
by such Holders, the Issuer or such third party will have the right, upon not less than 10 days nor more than 60 days’ prior notice
(provided that such notice is given not more than 30 days following such purchase pursuant to such tender offer described herein), to
redeem all Securities that remain outstanding following such purchase at a redemption price in cash equal to the price offered to each
other Holder in such tender offer plus, to the extent not included in such tender offer payment, accrued and unpaid interest, if any,
to, but excluding, the date of such redemption.

 

SECTION 3.02.        Applicability
of Article. Redemption of Securities at the election of the Issuer or otherwise, as permitted or required by any provision of this
Indenture (including the optional redemption provisions of Paragraph 5 of the Form of Security set forth in Exhibit A
hereto), shall be made in accordance with such provision and this Article 3.

 

SECTION 3.03.        Notices
to Trustee. If the Issuer elects to redeem Securities pursuant to the optional redemption provisions of Paragraph 5 of the Form of
Security set forth in Exhibit A hereto, it shall notify the Trustee and the Paying Agent in writing of (i) the particular
part of Paragraph 5 of the Form of Security set forth in Exhibit A hereto pursuant to which the redemption shall occur,
(ii) the redemption date, (iii) the principal amount of Securities to be redeemed and (iv) the redemption price. The Issuer
shall give notice to the Trustee and the Paying Agent provided for in this Section 3.03 at least 10 days but not more than
60 days before a redemption date if the redemption is pursuant to Paragraph 5 of the Form of Security set forth in Exhibit A
hereto. Any such notice may be canceled at any time prior to notice of such redemption being sent to any Holder and shall thereby
be void and of no effect.

 

SECTION 3.04.        Selection
of Securities to Be Redeemed. In the case of any partial redemption, selection of the Securities for redemption will be made by the
Trustee in accordance with the procedures of the Depository; provided, that no such selection shall result in a Holder of Securities
with a principal amount of Securities less than the minimum denomination for the Securities. The Securities to be redeemed shall be selected
from outstanding Securities not previously called for redemption. Securities and portions of them selected shall be in minimum amounts
of $2,000 or a whole multiple of $1,000 in excess thereof. Provisions of this Indenture that apply to Securities called for redemption
also apply to portions of Securities called for redemption.

 

SECTION 3.05.        Notice
of Optional Redemption.

 

(a)            At
least 10 days but not more than 60 days before a redemption date pursuant to Paragraph 5 of the Form of Security set forth
in Exhibit A hereto, the Issuer shall send or cause to be sent, electronically or by first-class mail, a notice of redemption
to each Holder (with a copy to the Trustee and Paying Agent) whose Securities are to be redeemed to such Holder’s registered address
or otherwise in accordance with the procedures of the Depository; provided that redemption notices may be provided more than 60
days prior to a redemption date if the notice is issued in connection with a satisfaction or discharge of this Indenture or defeasance
of the Securities pursuant to this Indenture.

 

    -60-

    

    

 

Any such notice shall identify the Securities to
be redeemed and shall state:

 

(i)             the
redemption date;

 

(ii)            the
redemption price and the amount of accrued interest to the redemption date;

 

(iii)           the
name and address of the Paying Agent;

 

(iv)           that
Securities called for redemption must be surrendered to the Paying Agent to collect the redemption price, plus accrued interest;

 

(v)            if
fewer than all the outstanding Securities are to be redeemed, the certificate numbers (if applicable) and principal amounts of the particular
Securities to be redeemed, the aggregate principal amount of the Securities to be redeemed and the aggregate principal amount of the
Securities to be outstanding after such partial redemption;

 

(vi)           that,
unless the Issuer defaults in making such redemption payment or any Paying Agent is prohibited from making such payment pursuant to the
terms of this Indenture, interest on Securities (or portion thereof) called for redemption ceases to accrue on and after the redemption
date;

 

(vii)          the
CUSIP number and ISIN, if any, printed on the Securities being redeemed; and

 

(viii)         that
no representation is made as to the correctness or accuracy of the CUSIP number or ISIN if any, listed in such notice or printed on the
Securities.

 

In connection with any redemption of Securities
(including with funds in an aggregate amount not exceeding the net cash proceeds of an Equity Offering), any such redemption may, at
the Issuer’s discretion, be subject to one or more conditions precedent, including the completion of any related Equity Offering.
In addition, if such redemption or notice is subject to satisfaction of one or more conditions precedent, such notice shall state that,
in the Issuer’s discretion, the redemption date may be delayed until such time (including more than 60 days after the date the
notice of redemption was sent) as any or all such conditions shall be satisfied (or waived by the Issuer in its sole discretion), 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. In addition, the Issuer may provide in such notice that payment
of the redemption price and performance of the Issuer’s obligations with respect to such redemption may be performed by another
Person.

 

(b)            At
the Issuer’s request, the Trustee shall give the notice of redemption in the Issuer’s name and at the Issuer’s expense;
provided, however, that the Issuer has delivered to the Trustee, at least 5 Business Days (unless a shorter period is acceptable
to the Trustee) prior to the date the redemption notice is sent to Holders, an Officer’s Certificate requesting that the Trustee
give such notice. In such event, the Issuer shall provide the Trustee in writing with the information required by this Section 3.05.

 

SECTION 3.06.       Effect
of Notice of Redemption. Once notice of redemption is provided in accordance with Section 3.05, Securities called for redemption
become due and payable on the redemption date and at the redemption price stated in the notice (except to the extent such redemption
is conditional as set forth in Section 3.05). Upon surrender to any Paying Agent, such Securities shall be paid at the redemption
price stated in the notice, plus accrued interest to the redemption date; provided, however, that if the redemption
date is after a regular record date and on or prior to the interest payment date, the accrued interest shall be payable to the Holder
of the redeemed Securities registered on the relevant record date. Failure to give notice or any defect in the notice to any Holder shall
not affect the validity of the notice to any other Holder.

 

    -61-

    

    

 

SECTION 3.07.         Deposit
of Redemption Price. Prior to 10:00 a.m., New York City time, on the redemption date, the Issuer shall deposit with the Paying
Agent (or, if UK Holdco or a Wholly Owned Subsidiary of UK Holdco is a Paying Agent, shall segregate and hold in trust) money sufficient
to pay the redemption price of and accrued interest on all Securities or portions thereof to be redeemed on that date other than Securities
or portions of Securities called for redemption that have been delivered by the Issuer to the Trustee for cancellation. On and after
the redemption date, interest shall cease to accrue on Securities or portions thereof called for redemption so long as the Issuer has
deposited with the Paying Agent funds sufficient to pay the principal of, plus accrued and unpaid interest on, the Securities
to be redeemed, unless the Paying Agent is prohibited from making such payment pursuant to the terms of this Indenture. For the avoidance
of doubt, the Paying Agent and the Trustee shall be held harmless and have no liability with respect to payments and disbursements to
be made by the Paying Agent and the Trustee until they have confirmed receipt of funds sufficient to make the relevant payment.

 

SECTION 3.08.         Securities
Redeemed in Part. In the case of Definitive Securities, upon surrender of a Security that is redeemed in part, the Issuer shall execute
and upon receipt of an Authentication Order the Trustee or the Authenticating Agent shall authenticate for the Holder (at the Issuer’s
expense) a new Security equal in principal amount to the unredeemed portion of the Security surrendered.

 

SECTION 3.09.         Offer
to Purchase by Application of Excess Proceeds or Collateral Excess Proceeds.

 

(a)            In
the event that, pursuant to Section 4.06 hereof, UK Holdco is required to commence an Asset Sale Offer or a Collateral Asset Sale
Offer, it will follow the procedures specified below.

 

(b)           The
Asset Sale Offer or Collateral Asset Sale Offer, as applicable, shall be made to all Holders with respect to offers to purchase, prepay
or redeem with the proceeds of sales of assets. The Asset Sale Offer or Collateral Asset Sale Offer, as applicable, will remain open
for a period of at least 20 Business Days following its commencement and not more than 30 Business Days, except to the extent that a
longer period is required by applicable law (the “Offer Period”). No later than five Business Days after the termination
of the Offer Period (the “Purchase Date”), UK Holdco will apply all Excess Proceeds or Collateral Excess Proceeds,
as applicable (the “Offer Amount”), to the purchase of Securities and, if applicable, other tendered Indebtedness
as provided in Section 4.06 or, if less than the Offer Amount has been tendered, all Securities and, if applicable, other Indebtedness
tendered in response to the Asset Sale Offer or Collateral Asset Sale Offer, as applicable. Payment for any Securities so purchased will
be made in the same manner as interest payments are made.

 

(c)            If
the Purchase Date is on or after an interest record date and on or before the related interest payment date, any accrued and unpaid interest
will be paid to the Person in whose name a Security is registered at the close of business on such record date, and no additional interest
will be payable to Holders who tender Securities pursuant to the Asset Sale Offer or Collateral Asset Sale Offer, as applicable.

 

    -62-

    

    

 

(d)            Upon
the commencement of an Asset Sale Offer or a Collateral Asset Sale Offer, UK Holdco shall send, or cause to be sent, electronically or
by first-class mail, or as otherwise provided in accordance with the procedures of the Depository, a written notice to the Trustee, the
Paying Agent and each of the Holders. The notice will contain all instructions and materials necessary to enable such Holders to tender
Securities pursuant to the Asset Sale Offer or Collateral Asset Sale Offer, as applicable. The notice, which will govern the terms of
the Asset Sale Offer or Collateral Asset Sale Offer, as applicable, will state:

 

(i)             that
the Asset Sale Offer or Collateral Asset Sale Offer, as applicable, is being made pursuant to this Section 3.09 and Section 4.06
hereof and the length of time the Asset Sale Offer or Collateral Asset Sale Offer, as applicable, will remain open;

 

(ii)            the
Offer Amount, the purchase price and the Purchase Date;

 

(iii)           that
Securities not tendered or accepted for payment will continue to accrue interest;

unless UK Holdco defaults in making such payment, Securities accepted for payment pursuant to the Asset Sale Offer or Collateral Asset
Sale Offer, as applicable, will cease to accrue interest after the Purchase Date;

 

(v)            that
Holders electing to have Securities purchased pursuant to an Asset Sale Offer or Collateral Asset Sale Offer, as applicable, may elect
to have Securities purchased in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof;

 

(vi)           that
Holders electing to have Securities purchased pursuant to any Asset Sale Offer or Collateral Asset Sale Offer, as applicable, will be
required to surrender the Securities, with the form entitled “Option of Holder to Elect Purchase” attached to the Securities
completed, or transfer by book-entry transfer, to UK Holdco, a depository, if appointed by UK Holdco, or a paying agent at the address
specified in the notice at least three days before the Purchase Date;

 

(vii)          that
Holders will be entitled to withdraw their election if UK Holdco, the Depository or the Paying Agent, as the case may be, receives, not
later than the expiration of the Offer Period, a facsimile transmission or letter setting forth the name of the Holder, the principal
amount of the Securities the Holder delivered for purchase and a statement that such Holder is withdrawing his election to have such
Securities purchased;

 

(viii)         that,
if the aggregate principal amount of Securities and, if applicable, other tendered Indebtedness surrendered by Holders thereof exceeds
the Offer Amount, UK Holdco will select the Securities and, if applicable, other tendered Indebtedness as provided in Section 4.06;
and

 

(ix)           that
Holders whose Securities were purchased only in part will be issued new Securities equal in principal amount to the unpurchased portion
of the Securities surrendered (or transferred by book-entry transfer).

 

    -63-

    

    

 

(e)            On
or before the Purchase Date, UK Holdco, to the extent lawful, will accept for payment, on a pro rata basis to the extent necessary (subject
to maintenance of authorized denominations), the Offer Amount of Securities or portions thereof and, if applicable, other Indebtedness
tendered pursuant to the Asset Sale Offer or Collateral Asset Sale Offer, as applicable, or if less than the Offer Amount has been tendered,
all Securities and, if applicable, other Indebtedness tendered, and will deliver or cause to be delivered to the Trustee the Securities
properly accepted together with an Officer’s Certificate stating that such Securities or portions thereof were accepted for payment
by UK Holdco in accordance with the terms of this Section 3.09. UK Holdco, the Depository or the Paying Agent, as the case may be,
will, not later than three Business Days after UK Holdco accepts the Offer Amount, mail or deliver to each tendering Holder an amount
equal to the purchase price of the Securities tendered by such Holder and accepted by UK Holdco for purchase, and UK Holdco will promptly
issue a new Security, and the Trustee or Authenticating Agent, upon receipt of an Authentication Order, will authenticate and mail or
deliver (or cause to be transferred by book entry) such new Security to such Holder, in a principal amount equal to any unpurchased portion
of the Security surrendered; provided that such Security shall be in a minimum principal amount of $2,000 or an integral multiple
of $1,000 in excess thereof. Any Securities not so accepted shall be promptly mailed or delivered by UK Holdco to the Holder thereof.
UK Holdco will publicly announce the results of the Asset Sale Offer or Collateral Asset Sale Offer, as applicable, on or as soon as
practicable after the Purchase Date.

 

(f)            Other
than as specifically provided in this Section 3.09, any purchase pursuant to this Section 3.09 shall be made in accordance
with the provisions of Sections 3.03 through 3.08 hereof and references therein to “redeem,” “redemption” and
similar words shall be deemed to refer to “purchase,” “repurchase” and similar words, as applicable.

 

SECTION 3.10.         [Reserved]

 

SECTION 3.11.         Mandatory
Redemption. Except as provided in Section 3.12, the Issuer is not required to redeem the Securities or make sinking fund
payments with respect to the Securities.

 

SECTION 3.12.         Escrow
of Gross Proceeds; Special Mandatory Redemption

 

(a)           The
Issuer and each of the Holders by acceptance of the Securities hereby authorizes and directs the Trustee to enter into an escrow agreement
(the “Escrow Agreement”) with the Unsecured Notes Trustee and Citibank, N.A., as escrow agent (the “Escrow
Agent”) and as account bank, pursuant to which the Issuer will deposit (or cause to be deposited) the gross proceeds of the
offering of the Securities into a segregated escrow account pursuant to the Escrow Agreement (the “Escrow Account”).
In the Escrow Agreement, the Issuer will grant to the Trustee for its benefit and the benefit of the Holders, a first priority security
interest in the Escrow Account and all amounts on deposit therein to secure the Obligations under the Securities, which shall automatically
be released and terminate upon disbursement of the property in the Escrow Account in accordance with the Escrow Agreement.

 

(b)           The
Escrow Agreement provides that the Issuer will only be entitled to direct the Escrow Agent to release the funds held in the Escrow Account
in accordance with the terms of the Escrow Agreement. Pursuant to the Escrow Agreement, the Escrow Agent will release funds held in the
Escrow Account (the “Release”) to, or at the order of, the Issuer (the date of such release being referred to as the
 “Escrow Release Date”) upon delivery by the Issuer to the Escrow Agent and the Trustee of an Officer’s Certificate
addressed to the Escrow Agent and the Trustee on or prior to November 8, 2021 (the “Escrow End Date”), certifying
that the Escrow Release Conditions will be met substantially concurrently with or promptly following the Release on the Escrow Release
Date.

 

    -64-

    

    

 

(c)            In
the event that (A) the Escrow Agent and the Trustee shall not have received the Officer’s Certificate described in Section 3.12(b) on
or prior to the Escrow End Date, (B) the Issuer shall notify the Escrow Agent and the Trustee in writing that in its reasonable
judgment the Escrow Release Conditions will not be satisfied on or prior to the Escrow End Date or (C) the Issuer shall notify the
Escrow Agent and the Trustee in writing that the ProQuest Agreement has been terminated (each such event described in clauses (A), (B) and
(C) above being a “Mandatory Redemption Event”), the Issuer will send a notice of redemption to Holders to redeem
all of the issued and outstanding Securities (the “Special Mandatory Redemption”) at a price (the “Special
Mandatory Redemption Price”) equal to 100% of the principal amount of the outstanding Securities, plus accrued and unpaid interest
from the Issue Date, to, but not including, the date of such redemption (the “Special Mandatory Redemption Date”),
which shall be the third Business Day following the Mandatory Redemption Event (or such date as may be required by the applicable procedures
of the Depository Trust Company). For purposes of determining the Special Mandatory Redemption Date, a Mandatory Redemption Event pursuant
to the preceding sentence shall be deemed to have occurred (x) in the case of clause (A), on the Escrow End Date, and (y) in
the case of clauses (B) and (C), on the date such written notice is delivered to the Escrow Agent and the Trustee (the date of any
such Mandatory Redemption Event, the “Mandatory Redemption Trigger Date”). Pursuant to the Escrow Agreement, within
one Business Day following the Mandatory Redemption Trigger Date, funds will be liquidated and released from the Escrow Account in order
to consummate the Special Mandatory Redemption. In the event that a Mandatory Redemption Event occurs and the amount in the Escrow Account
is not sufficient to fund the Special Mandatory Redemption Price, then the Issuer shall deposit, or cause Public Parent (or one of its
affiliates) to deposit, with the Trustee (or other paying agent for the Special Mandatory Redemption) no later than the close of business
on the second Business Day immediately preceding the Special Mandatory Redemption Date, an amount of cash necessary to fund the Special
Mandatory Redemption Price for the Securities, including accrued and unpaid interest from, and including, the Issue Date to, but excluding,
the Special Mandatory Redemption Date, plus an amount sufficient to pay any fees and expenses of the Trustee and the Collateral Agent
that have been incurred and are payable pursuant to this Indenture and which have been reasonably requested by the Trustee or the Collateral
Agent, as applicable, in writing prior to 10:00 am (New York City time) on the second Business Day immediately preceding the Special
Mandatory Redemption Date, provided that the Trustee has received written notice of the Special Mandatory Redemption on the Mandatory
Redemption Trigger Date (and if not, the Issuer shall pay, or cause Public Parent (or one of its affiliates) to pay, such fees and expenses
of the Trustee and the Collateral Agent directly to the Trustee and the Collateral Agent, respectively). In addition, the Issuer shall
furnish to the Trustee and the Escrow Agent an Officers’ Certificate setting forth: (i) the provision of this Indenture pursuant
to which the redemption shall occur; (ii) the Special Mandatory Redemption Date; (iii) the Special Mandatory Redemption Price
and (iv) instructions to deliver notice of the Special Mandatory Redemption to Holders, which notice, prepared by the Issuer, shall
contain the same information provided in clauses (i) through (iii) above and which shall be delivered to Holders no later than
the second Business Day immediately preceding the Special Mandatory Redemption Date. In connection with any redemption of the Securities
described in this Section 3.12, the Issuer will deliver, or upon request of the Issuer accompanied by the notice, the Trustee, on
behalf of the Issuer, will deliver electronically or mail to Holders a notice of Special Mandatory Redemption as soon as practicable
upon the occurrence of a Mandatory Redemption Event. Notwithstanding anything to the contrary in this Indenture, any redemption pursuant
to this Section 3.12(c) shall not be subject to the provisions of Sections 3.01 through 3.07 hereof. For the avoidance of doubt,
upon the satisfaction of the Escrow Release Conditions on or prior to the Escrow Release Date and consummation of the Release as provided
in the Escrow Agreement, the Securities shall no longer be subject to Special Mandatory Redemption pursuant to this Section 3.12(c).

 

(d)            By
its acceptance of the Securities, each Holder shall be deemed to authorize and direct the Trustee to enter into and perform its obligations,
if any, under the Escrow Agreement.

 

SECTION 3.13.         Activities
Prior to the Release. Prior to the Escrow Release Date, the primary activities of the Issuer will be restricted to issuing
the Securities and the Unsecured Notes, issuing capital stock to, and receiving capital contributions from, UK Holdco, Holdings or any
other Parent Holding Company, performing its obligations under the Securities, this Indenture, the Unsecured Notes, the Unsecured Notes
Indenture, the Escrow Agreement and the purchase agreement with the Initial Purchasers, performing any obligations under the ProQuest
Agreement, the Release and redeeming the Securities and the Unsecured Notes, if applicable, and conducting such other activities as are
necessary or appropriate in connection with the Transactions or to carry out the activities described in Sections 3.12.

faith judgment. While the Issuer or any direct or indirect parent of the Issuer is in registration with respect to an initial public offering,
the Issuer or any direct or indirect parent of the Issuer shall not be required to disclose any information or take any actions which,
in the view of the Issuer, would violate securities laws or the SEC’s gun jumping rules and shall not be deemed to have breached
its obligations described in this Indenture by virtue thereof.

(d)            Notwithstanding
the foregoing, for so long as the Public Parent or any other direct or indirect parent of the Issuer is a public reporting company (a
 “Reporting Company”), the Issuer shall be deemed to have satisfied its obligations in this Section 4.02 with respect
to furnishing financial information relating to UK Holdco by furnishing financial information relating to such Reporting Company upon
the filing of reports containing such information with the SEC or other securities commissions or stock exchange; provided, that
if a Reporting Company files such reports with the SEC and such Reporting Company has more than de minimis business operations separate
and apart from its ownership of UK Holdco, then the financial statements of such Reporting Company shall include (or the Issuer shall
otherwise furnish to the Trustee and holders of Securities in accordance with this covenant) a presentation of selected financial metrics
(in UK Holdco’s sole discretion), which need not be audited, that show the difference between the information relating to such Reporting
Company, on the one hand, and the information relating to UK Holdco and its Restricted Subsidiaries on a stand-alone basis, on the other
hand; provided, further, that no such disclosure will be required to be furnished if UK Holdco determines in its good faith judgment
that such disclosure is not material to the Holders. The Trustee will have no responsibility to determine whether such filing has occurred.

 

(e)            The
Issuer shall also furnish to Holders, securities analysts and prospective investors upon request the information required to be delivered
pursuant to Rule 144A(d)(4) under the Securities Act, so long as the Securities are not freely transferable under the Securities
Act.

 

(f)             If
UK Holdco has designated any of its Subsidiaries as an Unrestricted Subsidiary and if any such Unrestricted Subsidiary or group of Unrestricted
Subsidiaries, if taken together as one Subsidiary, would constitute a Significant Subsidiary of UK Holdco, then the annual and quarterly
information required by Section 4.02(a)(1) shall include a presentation of selected financial metrics (in UK Holdco’s
sole discretion), which need not be audited, of such Unrestricted Subsidiaries as a group in the “Management’s Discussion
and Analysis of Financial Condition and Results of Operation.”

 

(g)            Notwithstanding
anything herein to the contrary, the Issuer shall not be deemed to have failed to comply with any of its obligations hereunder for purposes
of Section 6.01(c) until 120 days after the date any report hereunder is due. Notwithstanding anything herein to the contrary,
any failure to comply with this Section 4.02 shall be automatically cured when the Issuer or any direct or indirect parent of the
Issuer, as the case may be, makes available all required reports to the Holders.

 

(h)            Delivery
of reports, information and documents to the Trustee is for informational purposes only and the information and the Trustee’s receipt
of such shall not constitute actual or constructive 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 Officer’s Certificates). The Trustee shall have no duty to review or analyze reports delivered to it.

of Consolidated Secured Debt Ratio or Consolidated First Lien Debt Ratio, as applicable, under this Section 4.03(b)(i)(2) on
such date but not, for the avoidance of doubt, excluded from any such calculation made on any such subsequent date),

 

provided,
that (x) any Indebtedness Incurred and outstanding pursuant to Sections 4.03(b)(i)(1) and (2) shall be deemed to be Indebtedness

for Section 4.03(b)(i)(2)(A), (y) any Indebtedness Incurred and outstanding pursuant to Section 4.03(b)(i)(2)(B) shall
be deemed to be Indebtedness secured by a Lien on the Collateral that ranks pari passu with the Liens securing the Securities,
whether or not so secured, solely for the purposes of calculating the Consolidated First Lien Debt Ratio for Section 4.03(b)(i)(2)(B) and
(z) any Indebtedness Incurred pursuant to this Section 4.03(b)(i) may be refinanced at any time if such refinancing does
not exceed the greater of (I) the aggregate principal amount of Indebtedness permitted to be Incurred pursuant to this Section 4.03(b)(i) on
the date of such refinancing and (II) the aggregate principal amount of the Indebtedness being refinanced at such time (together
with an amount necessary to pay accrued and unpaid interest and any fees and expenses, including any premium and defeasance costs, associated
with such refinancing) and, in the case of a refinancing of Indebtedness under the Credit Agreement outstanding on the Completion Date,

renew, refund, refinance, replace, defease or discharge any Indebtedness Incurred pursuant to this Section 4.03(b)(iv), not to exceed
the greater of (x) $550.0 million and (y) 47% of LTM EBITDA at any one time outstanding minus amounts Incurred and outstanding
under Section 4.03(b)(xiii) in respect of Indebtedness originally Incurred under this Section 4.03(b)(iv); provided
that Capitalized Lease Obligations incurred by UK Holdco or any Restricted Subsidiary pursuant to this Section 4.03(b)(iv) in
connection with a Sale/Leaseback Transaction shall not be subject to the foregoing limitation so long as the proceeds of such Sale/Leaseback

or a Guarantor, such Indebtedness is subordinated in right of payment to the Securities or the Guarantee of such Guarantor, as the case
may be; provided, further, that any subsequent issuance or transfer of any Capital Stock or any other event that results
in any Restricted Subsidiary lending such Indebtedness or Disqualified Stock, as applicable, ceasing to be a Restricted Subsidiary or
any other subsequent transfer of any such Indebtedness or Disqualified Stock, as applicable, (except to UK Holdco or another Restricted
Subsidiary) shall be deemed, in each case, to be an Incurrence of such Indebtedness or Disqualified Stock, as applicable;

(xii)         any

Subsidiaries so long as the Incurrence of such Indebtedness or other obligations by UK Holdco or such Restricted Subsidiary is permitted
under the terms of this Indenture; provided that if such Indebtedness is by its express terms subordinated in right of payment
to the Securities or the Guarantee of such Restricted Subsidiary, as applicable, any such guarantee of such Guarantor with respect to
such Indebtedness shall be subordinated in right of payment to such Guarantor’s Guarantee with respect to the Securities substantially
to the same extent as such Indebtedness is subordinated to the Securities or the Guarantee of such Restricted Subsidiary, as applicable;

 

    -71-

    

    

 

(xiii)         the
Incurrence by UK Holdco or any of its Restricted Subsidiaries of Indebtedness or Disqualified Stock or Preferred Stock of a Restricted

(3)         to
the extent such Refinancing Indebtedness refinances (x) Subordinated Indebtedness, such Refinancing Indebtedness is Subordinated

    -73-

    

    

 

(xxv)        customer
deposits and advance payments received in the ordinary course of business from customers for goods purchased in the ordinary course of
business;

 

(xxvi)       Indebtedness
Incurred pursuant to Sale/Leaseback Transactions; and

 

(xxvii)      Indebtedness,
Disqualified Stock or Preferred Stock of UK Holdco or a Restricted Subsidiary Incurred to finance or assumed in connection with an acquisition
of any assets (including Capital Stock), business or Person in an aggregate principal amount or liquidation preference that does not exceed
the greater of (x) $100.0 million and (y) 10% of LTM EBITDA at any one time outstanding (minus amounts Incurred and outstanding
under Section 4.03(b)(xiii) in respect of Indebtedness originally Incurred under this Section 4.03(b)(xxvii)).

 

(c)            For
purposes of determining compliance with this Section 4.03, in the event that an item of Indebtedness, Disqualified Stock or Preferred
Stock (or any portion thereof) meets the criteria of more than one of the categories of Permitted Debt or is entitled to be Incurred as
Ratio Debt, the Issuer shall, in its sole discretion, at the time of Incurrence, divide and/or classify, or at any later time re-divide
and/or reclassify, such item of Indebtedness, Disqualified Stock or Preferred Stock (or any portion thereof) in any manner that complies
with this Section 4.03. With respect to Sections 4.03(b)(iv), (xi), (xxiv) and (xxvii), if at any time that the Issuer would
be entitled to have Incurred any then outstanding item of Indebtedness as Ratio Debt, such item of Indebtedness shall be automatically
reclassified into an item of Indebtedness Incurred as Ratio Debt. Notwithstanding the foregoing, (x) all term loan Indebtedness under
the Credit Agreement outstanding on the Completion Date shall be deemed to have been Incurred pursuant to Section 4.03(b)(i)(1)(A) and
the Issuer shall not be permitted to reclassify all or any portion of such Indebtedness and (y) all Indebtedness under the Credit
Agreement in respect of revolving commitments available on the Completion Date shall be deemed to be Incurred pursuant to Section 4.03(b)(i)(1)(B) and
the Issuer shall not be permitted to reclassify all or any portion of such Indebtedness. The Issuer will also be entitled to divide, classify
or reclassify an item of Indebtedness in more than one of the types of permitted Indebtedness described in Sections 4.03(a) and (b) without
giving pro forma effect to the Indebtedness, Disqualified Stock or Preferred Stock (or any portion thereof) Incurred pursuant to Section 4.03(b) when
calculating the amount of Indebtedness, Disqualified Stock or Preferred Stock (or any portion thereof) that may be Incurred pursuant to
Section 4.03(a).

 

(d)            For
purposes of determining compliance with this Section 4.03, with respect to Indebtedness Incurred under a Debt Facility, reborrowings
of amounts previously repaid pursuant to “cash sweep” provisions or any similar provisions under a Debt Facility that provide
that Indebtedness is deemed to be repaid daily (or otherwise periodically) shall, subject to UK Holdco’s option to elect otherwise
pursuant to Section 4.03(f), only be deemed for purposes of this Section 4.03 to have been Incurred on the date such Indebtedness
was first Incurred and not on the date of any subsequent reborrowing thereof. Accrual of interest, the accretion of accreted value, the
amortization of original issue discount, the payment of interest in the form of additional Indebtedness with the same terms, the payment
of dividends on Disqualified Stock or Preferred Stock in the form of additional shares of Disqualified Stock or Preferred Stock of the
same class, the accretion of liquidation preference and increases in the amount of Indebtedness outstanding solely as a result of fluctuations
in the exchange rate of currencies shall not be deemed to be an Incurrence of Indebtedness, Disqualified Stock or Preferred Stock for
purposes of this Section 4.03. For the avoidance of doubt, the outstanding principal amount of any particular Indebtedness shall
be counted only once, and guarantees of, or obligations in respect of letters of credit relating to, Indebtedness that is otherwise
included in the determination of a particular amount of Indebtedness shall not be included in the determination of such amount of Indebtedness;
provided that the Incurrence of the Indebtedness represented by such guarantee or letter of credit, as the case may be, was in
compliance with this Section 4.03.

 

    -74-

    

    

 

(e)            For
purposes of determining compliance with any U.S. Dollar-denominated restriction on the Incurrence of Indebtedness, the U.S. Dollar-equivalent
principal amount of Indebtedness denominated in a currency other than U.S. Dollars shall be calculated based on the relevant currency
exchange rate in effect on the date such Indebtedness was Incurred, in the case of term debt, or first committed or first Incurred (whichever
yields the lower U.S. Dollar equivalent), in the case of revolving credit debt; provided that if such Indebtedness is Incurred
to refinance other Indebtedness denominated in a currency other than U.S. Dollars, and such refinancing would cause the applicable U.S.
Dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing,
such U.S. Dollar-denominated restriction shall be deemed not to have been exceeded so long as the principal amount of such refinancing
Indebtedness does not exceed the principal amount of such Indebtedness being refinanced (plus an amount not exceeding the amount otherwise
able to be Incurred pursuant to Section 4.03(b), it being understood that such amount shall constitute utilization of the applicable
basket or exception to this Section 4.03, as the case may be).

 

(f)            In
the event that, pursuant to either Section 4.03(a) or 4.03(b)(i)(2), UK Holdco or its Restricted Subsidiaries enters into or
increases commitments under a revolving credit facility, the Consolidated First Lien Debt Ratio, the Consolidated Secured Debt Ratio
and the Consolidated Total Debt Ratio of UK Holdco, will, for purposes of Section 4.03(a), Section 4.03(b)(i)(2) and clause
(26)(y) of the definition of “Permitted Liens” (solely to the extent the Obligations under such revolving credit facility
are secured by Liens on the Collateral) (collectively, the “Reserved Indebtedness Baskets”), as applicable, at UK
Holdco’s option, as elected on the date such revolving credit commitments are entered into or increased, either (a) be determined
on the date such revolving credit commitments are entered into or increased, in which case the Consolidated First Lien Debt Ratio, Consolidated
Secured Debt Ratio and Consolidated Total Debt Ratio, as applicable, for purposes of calculating compliance with (A) the Consolidated
Total Debt Ratio test set forth in Section 4.03(a), (B) the Consolidated First Lien Debt Ratio and the Consolidated Secured
Debt Ratio test sets forth in Section 4.03(b)(i)(2) and (C) the Consolidated First Lien Debt Ratio, Consolidated Secured
Debt Ratio and Consolidated Total Debt Ratio tests set forth in clause (26)(y) of the definition of “Permitted Liens”
(collectively, the “Reserved Indebtedness Tests”), as applicable, shall be calculated (whether on such date or thereafter
(but only with respect to such portion of commitments that have not been permanently reduced)) assuming that the full amount thereof
has been borrowed as of such date, and, if the applicable Reserved Indebtedness Test is satisfied with respect thereto on such date,

agreements governing the Indebtedness being refinanced (as determined by UK Holdco in good faith);

 

(16)         restrictions
or conditions contained in any trading, netting, operating, construction, service, supply, purchase, sale or other agreement to which
UK Holdco or any of its Restricted Subsidiaries is a party entered into in the ordinary course of business; provided that such
agreement prohibits the encumbrance of solely the property or assets of UK Holdco or such Restricted Subsidiary that are the subject of
such agreement, the payment rights arising thereunder or the proceeds thereof and does not extend to any other asset or property of UK
Holdco or such Restricted Subsidiary or the assets or property of any other Restricted Subsidiary; and

 

    -84- 

     

    

 

(17)         any
encumbrances or restrictions of the type referred to in clauses (a), (b) and (c) above imposed by any amendments, modifications,
restatements, renewals, increases, supplements, refundings, replacements or refinancings of the contracts, instruments or obligations
referred to in clauses (1) through (16) above; provided that such amendments, modifications, restatements, renewals,
increases, supplements, refundings, replacements or refinancings are, in the good faith judgment of the Issuer, not materially more restrictive
as a whole with respect to such dividend and other payment restrictions than those contained in the dividend or other payment restrictions
prior to such amendment, modification, restatement, renewal, increase, supplement, refunding, replacement or refinancing.

 

For purposes of determining compliance with this Section 4.05,
(i) the priority of any Preferred Stock in receiving dividends or liquidating distributions prior to dividends or liquidating distributions
being paid on common stock shall not be deemed a restriction on the ability to make distributions on Capital Stock and (ii) the subordination
of loans or advances made to UK Holdco or a Restricted Subsidiary to other Indebtedness Incurred by UK Holdco or any such Restricted Subsidiary
shall not be deemed a restriction on the ability to make loans or advances.

 

SECTION 4.06.      Asset
Sales.

 

(a)           UK
Holdco shall not, and shall not permit any of its Restricted Subsidiaries to, cause or make an Asset Sale, unless:

 

(1)           UK
Holdco or any of its Restricted Subsidiaries, as the case may be, receives consideration at the time of such Asset Sale at least equal
to the Fair Market Value (as determined in good faith by the Issuer) of the Equity Interests issued or assets sold or otherwise disposed
of; and

 

(2)           except
in the case of a Permitted Asset Swap, at least 75% of the consideration therefor received by UK Holdco or such Restricted Subsidiary,
as the case may be, together with the consideration for all other Asset Sales that have been made since the Existing Notes Issue Date
(on a cumulative basis), is in the form of Cash Equivalents; provided, however, that in the case of Asset Sales involving
the disposition of non-core assets (as determined by UK Holdco in its good faith judgment; provided the value of such non-core
assets does not exceed 50% of the consideration payable in connection with such acquisition) acquired as part of any acquisition after
the Existing Notes Issue Date, only 50% of the consideration therefor, together with the consideration for all other Asset Sales made
pursuant to this proviso since the Existing Notes Issue Date, must be in the form of Cash Equivalents; provided, further,
that the amount of:

 

(i)    any
liabilities (as shown on UK Holdco’s or such Restricted Subsidiary’s most recent balance sheet or in the notes thereto or,
if Incurred, increased or decreased subsequent to the date of such balance sheet, such liabilities that would have been reflected in UK
Holdco’s or such Restricted Subsidiary’s balance sheet or in the notes thereto if such Incurrence, increase or decrease had
taken place on the date of such balance sheet, as reasonably determined in good faith by the Issuer) of UK Holdco or any Restricted Subsidiary
(other than liabilities that are by their terms subordinated to the Securities) that are assumed by the transferee (or a third party on
behalf of the transferee) of any such assets or Equity Interests pursuant to an agreement that releases or indemnifies UK Holdco or such
Restricted Subsidiary (or a third party on behalf of the transferee), as the case may be, from further liability;

 

(ii)     any
notes or other obligations or other securities or assets received by UK Holdco or such Restricted Subsidiary from such transferee that
are converted by UK Holdco or such Restricted Subsidiary into cash within 180 days of the receipt thereof (to the extent of the cash received);

 

    -85- 

     

    

 

(iii)  any
Designated Non-cash Consideration received by UK Holdco or any of its Restricted Subsidiaries in such Asset Sale having an aggregate Fair
Market Value, taken together with all other Designated Non-cash Consideration received pursuant to this clause (iii) that is
at that time outstanding, not to exceed the greater of (x) $275.0 million and (y) 24% of LTM EBITDA, at the time of the receipt
of such Designated Non-cash Consideration (with the Fair Market Value of each item of Designated Non-cash Consideration being measured
at the time received and without giving effect to subsequent changes in value);

 

(iv)  Indebtedness
of any Restricted Subsidiary that is no longer a Restricted Subsidiary as a result of such Asset Sale, to the extent that UK Holdco and
each other Restricted Subsidiary are released from any Guarantee of such Indebtedness in connection with such Asset Sale; and

 

(v)   consideration
consisting of Indebtedness of the Issuer or any Guarantor received from Persons who are not UK Holdco or a Restricted Subsidiary, shall
each be deemed to be Cash Equivalents for the purposes of this Section 4.06.

 

(b)          Within
450 days after UK Holdco’s or any Restricted Subsidiary’s receipt of the Net Cash Proceeds of any Asset Sale, UK Holdco
or such Restricted Subsidiary may apply the Net Cash Proceeds from such Asset Sale, at its option:

 

(i)            to
the extent such Net Cash Proceeds are from an Asset Sale of Collateral, to repay any First Priority Lien Obligations (other than the Securities),
including Indebtedness under the Credit Agreement (and, if the Indebtedness repaid is revolving credit Indebtedness, to correspondingly
reduce commitments with respect thereto) or the Existing Notes; provided that if the Issuer or any Guarantor shall so reduce such
First Priority Lien Obligations, the Issuer or such Guarantor will equally and ratably reduce Obligations under the Securities (A) through
open-market purchases (provided that such purchases are at or above 100% of the principal amount thereof), (B) by redeeming
Securities if the Securities are then redeemable as provided under Article 3 or (C) by making an offer (in accordance with the
procedures set forth below for a Collateral Asset Sale Offer) to all Holders to purchase at a purchase price equal to 100% of the principal
amount thereof, plus accrued and unpaid interest, if any, on the principal amount of the Securities,

 

(ii)           to
the extent such Net Cash Proceeds are from an Asset Sale that does not constitute Collateral, (x) to repay any Indebtedness secured
by a Lien on such asset or (y) to repay any Indebtedness of the Issuer or any Guarantor that ranks equally in right of payment with
the Securities or the relevant Guarantee (and, if the Indebtedness repaid is revolving credit Indebtedness, to correspondingly reduce
commitments with respect thereto); provided that if the Issuer or any Guarantor shall so reduce such Indebtedness, the Issuer or
such Guarantor will equally and ratably reduce Obligations under the Securities (A) through open-market purchases (provided
that such purchases are at or above 100% of the principal amount thereof), (B) by redeeming Securities if the Securities are then
redeemable as provided under Article 3 or (C) by making an offer (in accordance with the procedures set forth below for an Asset
Sale Offer) to all Holders to purchase at a purchase price equal to 100% of the principal amount thereof, plus accrued and unpaid
interest, if any, on the principal amount of the Securities,

 

    -86- 

     

    

 

(iii)          to
make an investment in any one or more businesses (provided that if such investment is in the form of the acquisition of Capital
Stock of a Person, such acquisition results in such Person becoming a Restricted Subsidiary), assets, or property or capital expenditures,
in each case used or useful in a Similar Business,

 

(iv)          to
make an investment in any one or more businesses (provided that if such investment is in the form of the acquisition of Capital
Stock of a Person, such acquisition results in such Person becoming a Restricted Subsidiary), properties or assets that replace the properties
and assets that are the subject of such Asset Sale (“Replacement Assets”),

 

(v)           to
repay Indebtedness of a Restricted Subsidiary that is not a Guarantor (and, if the Indebtedness repaid is revolving credit Indebtedness,
to correspondingly reduce commitments with respect thereto), other than Indebtedness owed to UK Holdco or another Restricted Subsidiary,
or

 

(vi)         any
combination of the foregoing;

 

provided
that UK Holdco and its Restricted Subsidiaries shall be deemed to have complied with Sections 4.06(b)(iii) and (iv) if and to
the extent that, within 450 days after the Asset Sale that generated the Net Cash Proceeds, the Issuer or UK Holdco has entered into and
not abandoned or rejected a binding agreement to acquire the assets or Capital Stock of a Similar Business, make an Investment in Replacement
Assets or make a capital expenditure in compliance with the provision described in Sections 4.06(b)(iii) and (iv) (an “Acceptable
Agreement”) with the good faith expectation that such acquisition, purchase or capital expenditure will be completed within
180 days after the end of such 450-day period; provided, further, that if any Acceptable Agreement is later cancelled or
terminated for any reason after the end of such 450-day period and before such Net Cash Proceeds are applied, then such Net Cash Proceeds
shall constitute Collateral Excess Proceeds or Excess Proceeds, as the case may be.

 

Notwithstanding the foregoing, to the extent that
(x) a repatriation or other distribution of any or all of the Net Cash Proceeds of any Asset Sale by a Subsidiary to UK Holdco (and
payment of such amounts by UK Holdco to the Issuer) is prohibited or delayed by applicable local law (including financial assistance and
corporate benefit restrictions and fiduciary and statutory duties of the relevant directors), (y) such distribution would present
a material risk of liability for the applicable Subsidiary or its directors or officers (or gives rise to a material risk of breach of
fiduciary or statutory duties by any director or officers) or (z) a distribution of any or all of the Net Cash Proceeds of any Asset
Sale by a Subsidiary of the Issuer to the Issuer or by any Subsidiary to UK Holdco (and payment of such amounts by UK Holdco to the Issuer)
would reasonably be expected to result in material adverse Tax consequences, as determined by UK Holdco in its sole discretion, the portion
of such Net Cash Proceeds so affected will not be required to be applied in compliance with this Section 4.06 and may be retained
by the applicable Subsidiary; provided that within 450 days of the receipt of such Net Cash Proceeds, UK Holdco shall use commercially
reasonable efforts to permit repatriation of the proceeds that would otherwise be subject to this Section 4.06, if such repatriation
(A) can be effected without violating local law, (B) would not present a material risk as described in clause (y) above
and (C) can be effected without incurring material adverse Tax consequences, and, if such proceeds may be repatriated such proceeds
shall be required to be applied in compliance with this Section 4.06 within such 450-day period, subject to the immediately preceding
paragraph of this Section 4.06(b).

 

Pending the final application of any such Net Cash
Proceeds, UK Holdco or such Restricted Subsidiary may temporarily reduce Indebtedness under a revolving credit facility, if any, or otherwise
invest such Net Cash Proceeds in Cash Equivalents or Investment Grade Securities.

 

    -87- 

     

    

 

Any Net Cash Proceeds from any Asset Sale of Collateral
that are not applied as provided and within the time period set forth in the second and third immediately preceding paragraphs (it being
understood that any portion of such Net Cash Proceeds used to make an offer to purchase Securities, as described in Section 4.06(b)(ii),
shall be deemed to have been invested whether or not such offer is accepted) will be deemed to constitute “Collateral Excess
Proceeds.” When the aggregate amount of Collateral Excess Proceeds exceeds $100.0 million, the Issuer shall make an offer to
all Holders of the Securities, and if required by the terms of any First Priority Lien Obligations or other Obligations secured by a Lien
permitted under this Indenture on the Collateral disposed of (which Lien is not subordinate to the Lien of the Securities with respect
to the Collateral), to all Holders of such First Priority Lien Obligations or other Obligations, as appropriate, on a pro rata basis (a
 “Collateral Asset Sale Offer”), to purchase the maximum principal amount of Securities and such other Indebtedness
that is in minimum denominations of at least $2,000 and integral multiples of $1,000 in excess thereof with respect to the Securities
that may be purchased out of the Collateral Excess Proceeds at an offer price in cash in an amount equal to 100% of the principal amount
thereof (or, in the event such other First Priority Lien Obligations or other Obligations of the Issuer or any Guarantor were issued with
significant original issue discount, 100% of the accreted value thereof), plus accrued and unpaid interest, if any, to, but not
including, the date fixed for the closing of such offer, in accordance with the procedures set forth in this Indenture or the agreement
governing such First Priority Lien Obligations or other Obligations. The Issuer will commence a Collateral Asset Sale Offer with respect
to Excess Proceeds within ten (10) Business Days after the date that Collateral Excess Proceeds exceeds $100.0 million by mailing
or electronically sending the notice required pursuant to the terms of this Indenture, with a copy to the Trustee. The Issuer may satisfy
the foregoing obligations with respect to any Net Cash Proceeds from an Asset Sale of Collateral by making a Collateral Asset Sale Offer
with respect to such Net Cash Proceeds prior to the expiration of the relevant 450 days (or such longer period provided above) or with
respect to Collateral Excess Proceeds of $100.0 million or less. To the extent that the aggregate amount of Securities and such other
First Priority Lien Obligations or other Obligations of the Issuer or any Guarantor tendered pursuant to a Collateral Asset Sale Offer
is less than the Collateral Excess Proceeds, the Issuer may use any remaining Collateral Excess Proceeds (any such amount, “Retained
Declined Collateral Proceeds”) for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount
of Securities or such other First Priority Lien Obligations or other Obligations of the Issuer or any Guarantor surrendered by Holders
thereof exceeds the amount of Collateral Excess Proceeds, the Issuer shall select or cause to be selected the Securities and the trustee
or agent for such other Indebtedness shall select such other Indebtedness to be purchased on a pro rata basis based on the accreted value
or principal amount of the Securities or such Indebtedness tendered (subject to adjustment so that no Securities in an unauthorized denomination
shall remain outstanding after such purchase). Upon completion of any such Collateral Asset Sale Offer, the amount of Collateral Excess
Proceeds shall be reset at zero.

 

    -88- 

     

    

 

Any Net Cash Proceeds from any Asset Sale that does
not constitute Collateral that are not applied as provided and within the time period set forth in the immediately preceding paragraphs
(it being understood that any portion of such Net Cash Proceeds used to make an offer to purchase Securities, as described in Section 4.06(b)(ii),
shall be deemed to have been invested whether or not such offer is accepted) will be deemed to constitute “Excess Proceeds.”
When the aggregate amount of Excess Proceeds exceeds $100.0 million, the Issuer shall make an offer to all Holders of Securities, and
if required by the terms of any Indebtedness of the Issuer or any Guarantor that ranks equally in right of payment with the Securities
or the relevant Guarantee, to the holders of such Indebtedness (an “Asset Sale Offer”) to purchase the maximum principal
amount of Securities and such Indebtedness that is in minimum denominations of at least $2,000 and integral multiples of $1,000 in excess
thereof with respect to the Securities that may be purchased out of the Excess Proceeds at an offer price in cash in an amount equal to
100% of the principal amount thereof (or, in the event such Indebtedness of the Issuer or any Guarantor that ranks equally in right of
payment with the Securities or the relevant Guarantee was issued with significant original issue discount, 100% of the accreted value
thereof), plus accrued and unpaid interest, if any, but not including, to the date fixed for the closing of such offer, in accordance
with the procedures set forth in this Indenture or the agreement governing such other Indebtedness. The Issuer will commence an Asset
Sale Offer with respect to Excess Proceeds within ten (10) Business Days after the date that Excess Proceeds exceeds $100.0 million
by mailing or electronically sending the notice required pursuant to the terms of this Indenture, with a copy to the Trustee. The Issuer
may satisfy the foregoing obligations with respect to any Net Cash Proceeds from an Asset Sale by making an Asset Sale Offer with respect
to such Net Cash Proceeds prior to the expiration of the relevant 450 days (or such longer period provided above) or with respect to Excess
Proceeds of $100.0 million or less. To the extent that the aggregate amount of Securities and such Indebtedness of the Issuer or any Guarantor
that ranks equally in right of payment with the Securities or the relevant Guarantee tendered pursuant to an Asset Sale Offer is less
than the Excess Proceeds, the Issuer may use any remaining Excess Proceeds (any such amount, “Retained Declined Proceeds”)
for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of Securities or the Indebtedness of the
Issuer or any Guarantor that ranks equally in right of payment with the Securities or the relevant Guarantee surrendered by holders thereof
exceeds the amount of Excess Proceeds, the Issuer shall select or cause to be selected the Securities and the trustee or agent for such
other Indebtedness shall select such other Indebtedness to be purchased on a pro rata basis based on the accreted value or principal amount
of the Securities or such Indebtedness tendered (subject to adjustment so that no Securities in an unauthorized denomination shall remain
outstanding after such purchase). Upon completion of any such Asset Sale Offer, the amount of Excess Proceeds shall be reset at zero.

 

(c)          The
Issuer will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations to the
extent such laws or regulations are applicable in connection with the repurchase of the Securities pursuant to an Asset Sale Offer or
Collateral Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this
Indenture, the Issuer will comply with the applicable securities laws and regulations and shall be deemed not to have breached its obligations
described in this Indenture by virtue thereof.

 

SECTION 4.07.      Transactions
with Affiliates.

 

(a)           UK
Holdco shall not, and shall not permit any Restricted Subsidiaries of UK Holdco to, directly or indirectly, make any payment to, or sell,
lease, transfer or otherwise dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or
make or amend any transaction or series of transactions, contract, agreement, understanding, loan, advance or guarantee with, or for the
benefit of, any Affiliate of UK Holdco (each of the foregoing, an “Affiliate Transaction”) involving aggregate consideration
in excess of the greater of $75.0 million and 8% of LTM EBITDA, unless:

 

(i)            Such
Affiliate Transaction is on terms that are not materially less favorable to UK Holdco or the relevant Restricted Subsidiary than those
that could have been obtained in a comparable transaction by UK Holdco or such Restricted Subsidiary with an unrelated Person; and

 

(ii)           with
respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of the greater
of $100.0 million and 10% LTM EBITDA, the Issuer delivers to the Trustee a resolution adopted in good faith by the majority of the
Board of Directors of the Issuer or any other direct or indirect parent of the Issuer approving such Affiliate Transaction and set forth
in an Officer’s Certificate provided to the Trustee certifying that such Affiliate Transaction complies with clause (i) above.

 

    -89- 

     

    

 

(b)          The
provisions of Section 4.07(a) shall not apply to the following:

as a result of such transaction) and (B) any merger or consolidation of UK Holdco or any direct parent company of UK Holdco; provided
that such parent company shall have no material liabilities and no material assets other than cash, Cash Equivalents and the Capital Stock
of UK Holdco and such merger or consolidation is otherwise in compliance with the terms of this Indenture and effected for a bona fide
business purpose;

 

(ii)           (x) Restricted

(or any direct or indirect parent thereof) in good faith;

 

(iv)         the
payment of reasonable and customary fees and reimbursements paid to, and indemnity and similar arrangements provided on behalf of, former,
current or future officers, directors, managers, employees or consultants of UK Holdco or any Restricted Subsidiary or any direct or indirect
parent of UK Holdco;

 

(v)          transactions
in which UK Holdco or any of the Restricted Subsidiaries, as the case may be, delivers to the Trustee a letter from an Independent Financial
Advisor stating that such transaction is fair to UK Holdco or such Restricted Subsidiary from a financial point of view or meets the requirements
of Section 4.07(a)(i);

 

(vi)         payments,
loans or advances to employees or consultants or guarantees in respect thereof (or cancellation of loans, advances or guarantees) for
bona fide business purposes in the ordinary course of business;

 

(vii)        any
agreement, instrument or arrangement as in effect as of the Completion Date or any transaction contemplated thereby, or any amendment
thereto (so long as any such amendment is not disadvantageous to the Holders in any material respect when taken as a whole as compared
to the applicable agreement as in effect on the Completion Date as reasonably determined by the Issuer in good faith);

 

(viii)       the
existence of, or the performance by UK Holdco or any of its Restricted Subsidiaries of its obligations under the terms of any stockholders
or similar agreement (including any registration rights agreement or purchase agreement related thereto) to which it is a party as of
the Completion Date, and any amendment thereto or similar transactions, agreements or arrangements which it may enter into thereafter;
provided, however, that the existence of, or the performance by UK Holdco or any of its Restricted Subsidiaries of its obligations
under, any future amendment to any such existing transaction, agreement or arrangement or under any similar transaction, agreement or
arrangement entered into after the Completion Date shall only be permitted by this clause (viii) to the extent that the terms
of any such existing transaction, agreement or arrangement together with all amendments thereto, taken as a whole, or new transaction,
agreement or arrangement are not otherwise more disadvantageous to the Holders in any material respect when taken as a whole as compared
to the original transaction, agreement or arrangement as in effect on the Completion Date;

 

    -90- 

     

    

 

(ix)          (A) transactions
with customers, clients, suppliers or purchasers or sellers of goods or services, in each case in the ordinary course of business and
otherwise in compliance with the terms of this Indenture, which are fair to UK Holdco and its Restricted Subsidiaries in the reasonable
determination of UK Holdco, and are on terms at least as favorable as might reasonably have been obtained at such time from an unaffiliated

(x)           any
transaction effected as part of a Qualified Receivables Financing;

faith;

    -91- 

     

    

 

(xxiii)      transactions

such Person entered into in the ordinary course of business;

 

(xxiv)      transactions
with Affiliates solely in their capacity as holders of Indebtedness, Equity Interests of UK Holdco or any of its Subsidiaries, so long
as such transaction is with all holders of such class (and there are such non-Affiliate holders) and such Affiliates are treated no more

(xxvii)     transactions
between UK Holdco or any of its Restricted Subsidiaries and any Person that is an Affiliate thereof solely due to the fact that a director

such director abstains from voting as a director of the Issuer or such direct or indirect parent of the Issuer, as the case may be, on
any matter involving such other Person.

 

SECTION 4.08.      Change
of Control.

 

(a)           Upon
the occurrence of a Change of Control, each Holder shall have the right to require the Issuer to repurchase all or any part of such Holder’s
Securities at a purchase price in cash equal to 101% of the principal amount thereof (the “Change of Control Payment”),
plus accrued and unpaid interest, if any, to, but not including, the date of repurchase (subject to the right of the Holders of
record on the relevant record date to receive interest due on the relevant interest payment date), in accordance with the terms contemplated
in this Section 4.08; provided, however, that notwithstanding the occurrence of a Change of Control, the Issuer shall
not be obligated to purchase any Securities pursuant to this Section 4.08 in the event that it has exercised its right to redeem
such Securities of such Holder in accordance with Article 3 of this Indenture.

 

(b)          Within
30 days following any Change of Control, except to the extent that the Issuer has exercised its right to redeem the Securities in
accordance with Article 3 of this Indenture, the Issuer shall cause a notice to be sent electronically, or, at the Issuer’s
option, mailed by first-class mail or otherwise provided in accordance with the procedures of the Depository (a “Change of Control
Offer”) to each Holder with a copy to the Trustee describing:

 

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

 

    -92- 

     

    

 

(ii)           the
transaction or transactions constitute a Change of Control;

 

(iii)          the
repurchase date (which shall be no earlier than 10 days nor later than 60 days from the date such notice is sent, except if delivered
in advance of the occurrence of such Change of Control in accordance with this Section 4.08); and

 

(iv)         the
instructions determined by the Issuer that a Holder must follow in order to have its Securities purchased; provided, however, if
a Change of Control occurs prior to the Completion Date, the Issuer will not be required to make a Change of Control Offer until after
the Completion Date

 

(c)           Holders
electing to have a Security purchased shall be required to surrender the Security, with an appropriate form duly completed, to the Issuer
at the address specified in the notice at least three Business Days prior to the purchase date. The Holders shall be entitled to withdraw

or letter setting forth the name of the Holder, the principal amount of the Security which was delivered for purchase by the Holder and
a statement that such Holder is withdrawing his election to have such Security purchased. Holders whose Securities are purchased only
in part shall be issued new Securities equal in principal amount to the unpurchased portion of the Securities surrendered.

 

(d)          On
the purchase date, all Securities purchased by the Issuer under this Section 4.08 shall be delivered to the Trustee for cancellation,
and the Issuer shall pay the purchase price plus accrued and unpaid interest to the Holders entitled thereto.

 

(e)           Notwithstanding
the foregoing provisions of this Section 4.08, the Issuer shall not be required to make a Change of Control Offer upon a Change of
Control if 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 Section 4.08(b) applicable to a Change of Control Offer made by the Issuer and purchases all Securities validly
tendered and not withdrawn under such Change of Control Offer. In addition, for the avoidance of doubt, the Issuer will not be required
to make a Change of Control Offer if the Issuer has previously or concurrently with the Change of Control, issued a notice of a full redemption
pursuant to the provisions set forth under Article 3 of this Indenture.

 

(f)           At
the time the Issuer delivers Securities to the Trustee which are to be accepted for purchase, the Issuer shall also deliver an Officer’s
Certificate stating that such Securities are to be accepted by the Issuer pursuant to and in accordance with the terms of this Section 4.08.
A Security shall be deemed to have been accepted for purchase at the time the Trustee or the Paying Agent, directly or through an agent,
mails or delivers payment therefor to the surrendering Holder.

 

(g)          Prior
to any Change of Control Offer, the Issuer shall deliver to the Trustee an Officer’s Certificate stating that all conditions precedent
contained herein to the right of the Issuer to make such offer have been complied with.

 

(h)          The
Issuer shall comply, to the extent applicable, with the requirements of Rule 14(e)-1 of the Exchange Act and any other securities
laws or regulations in connection with the repurchase of Securities pursuant to this Section 4.08. To the extent that the provisions
of any securities laws or regulations conflict with provisions of this Section 4.08, the Issuer shall comply with the applicable
securities laws and regulations and shall not be deemed to have breached its obligations under this Section 4.08 by virtue of such
compliance.

 

    -93- 

     

    

 

(i)            Notwithstanding
the foregoing provisions, a Change of Control Offer may be made in advance of a Change of Control, and conditioned upon such Change of
Control, with a purchase date to occur upon, or within a specified period of time not to exceed 15 days after, the consummation of such
Change of Control.

 

SECTION 4.09.      Compliance
Certificate. UK Holdco shall deliver to the Trustee within 120 days after the end of each fiscal year of UK Holdco an Officer’s
Certificate, the signer of which shall be the principal executive officer, principal accounting officer, principal financial officer or
duly authorized manager or director of UK Holdco, stating that in the course of the performance by the signer of his or her duties as
an officer, manager or director of UK Holdco he or she would normally have knowledge of any Default and whether or not the signer knows
of any Default that occurred during such period. If he or she does, the certificate shall describe the Default, its status and what action
UK Holdco or the Issuer, as applicable, is taking or proposes to take with respect thereto.

 

SECTION 4.10.      Future
Guarantors. Subject to the Guaranty and Security Principles, if, on or after the Completion Date, any Restricted Subsidiary (including
any newly formed, newly acquired or newly redesignated Restricted Subsidiary) other than an Excluded Subsidiary that is not then a Guarantor
guarantees or Incurs any Indebtedness under the Credit Agreement, then UK Holdco shall cause such Restricted Subsidiary to (i) execute
and deliver to the Trustee a supplemental indenture pursuant to which such Subsidiary shall become a Guarantor under this Indenture and
(ii) grant Liens on its assets as set forth under Section 4.17, in each case within 20 Business Days of the date that such guarantee
or Lien, as applicable, has been granted pursuant to the Credit Agreement (giving effect to any extension granted by the Credit Agreement
Collateral Agent thereunder).

 

SECTION 4.11.      Liens.
UK Holdco shall not, and shall not permit the Issuer or any of UK Holdco’s Restricted Subsidiaries to, directly or indirectly, create
or Incur any Lien (each, a “Subject Lien”) that secures obligations under any Indebtedness on any asset or property
now owned or hereafter acquired (other than Permitted Liens), unless, in the case of any Subject Lien on any asset or property that does
not constitute Collateral, the Securities (or a Guarantee, in the case of Subject Liens on assets or property of a Restricted Subsidiary
that is a Guarantor) are equally and ratably secured with (or on a senior basis to, in the case such Subject Lien secures any Subordinated
Indebtedness) the Obligations secured by such Subject Lien.

 

Notwithstanding the foregoing, any Lien securing
the Securities granted pursuant to the last clause of the preceding paragraph of this Section 4.11 shall provide by its terms that
such Lien shall be automatically and unconditionally released and discharged upon (a) the release and discharge of the Subject Lien
(including any deemed release upon payment in full of all obligations under such Indebtedness (except upon foreclosure or default of such
Indebtedness)), (b) any sale, exchange or transfer to any Person other than the Issuer or any Guarantor of the property or assets
secured by such Subject Lien, or of all of the Capital Stock held by the Issuer or any Guarantor in, or all or substantially all the assets
of, any Guarantor creating such Subject Lien in each case in accordance with the terms of this Indenture, (c) payment in full of
the principal of, and accrued and unpaid interest, if any, on the Securities, or (d) a defeasance or discharge of the Securities
in accordance with the procedures described in Article 8, and in each case, subject to Section 10.02.

 

For purposes of determining compliance with this
Section 4.11, (x) a Lien need not be Incurred solely by reference to one category of Permitted Liens but may be Incurred under
any combination of such categories (including in part under one such category and in part under any other such category) and (y) in
the event that a Lien (or any portion thereof) meets the criteria of one or more of such categories of Permitted Liens, the Issuer shall,
in its sole discretion, divide, classify or may subsequently reclassify at any time such Lien (or any portion thereof) in any manner that
complies with this Section 4.11 and the definition of “Permitted Liens”; provided that any Liens in respect of
Indebtedness Incurred pursuant to Section 4.03(b)(i)(1)(A) shall be deemed to have been Incurred pursuant to clause (26)(x) of
the definition of “Permitted Liens,” and the Issuer shall not be permitted to reclassify all or any portion of such Liens.

 

    -94- 

     

    

 

With respect to any Lien securing Indebtedness that
was permitted to secure such Indebtedness at the time of the Incurrence of such Indebtedness, such Lien shall also be permitted to secure
any Increased Amount of such Indebtedness. The “Increased Amount” of any Indebtedness shall mean any increase in the
amount of such Indebtedness in connection with any accrual of interest, the accretion of accreted value, the amortization of original
issue discount, the payment of interest in the form of additional Indebtedness with the same terms, accretion of original issue discount
or liquidation preference, any fees, underwriting discounts, accrued and unpaid interest, premiums and other costs and expenses incurred
in connection therewith and increases in the amount of Indebtedness outstanding solely as a result of fluctuations in the exchange rate
of currencies or increases in the value of property securing Indebtedness.

 

SECTION 4.12.      Maintenance
of Office or Agency.

 

(a)          The
Issuer shall maintain, in the United States, an office or agency (which may be an office of the Trustee or an affiliate of the Trustee
or Registrar) where Securities may be surrendered for registration of transfer or for exchange and where notices and demands to or upon
the Issuer in respect of the Securities and this Indenture may be served. The Issuer shall give prompt written notice to the Trustee of
the location, and any change in the location, of such office or agency. If at any time the Issuer shall fail to maintain any such required
office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may
be made or served at the corporate trust office of the Trustee as set forth in Section 12.02.

 

(b)          The
Issuer may also from time to time designate one or more other offices or agencies where the Securities may be presented or surrendered
for any or all such purposes and may from time to time rescind such designations. The Issuer shall give prompt written notice to the Trustee
of any such designation or rescission and of any change in the location of any such other office or agency; provided that no office
or agency of the Trustee shall be an office or agency of the Issuer for purposes of service of legal process against the Issuer or any
Guarantor.

 

(c)          The
Issuer hereby designates the corporate trust office of the Trustee or its agent as such office or agency of the Issuer in accordance with
Section 2.04.

 

SECTION 4.13.      Suspension
of Covenants.

 

(a)          If
on any date following the Completion Date (i) the Securities have Investment Grade Ratings from both Rating Agencies and (ii) no
Default has occurred and is continuing under this Indenture (the occurrence of the events described in the foregoing clauses (i) and
(ii) being collectively referred to as a “Covenant Suspension Event”), UK Holdco and its Restricted Subsidiaries
shall not be subject to Section 4.03, Section 4.04, Section 4.05, Section 4.06, Section 4.07, Section 4.10,
Section 5.01(a)(iv), Section 5.01(b)(iv) and Section 5.01(c)(iv) (collectively, the “Suspended Covenants”).

 

(b)          In
the event that UK Holdco and its Restricted Subsidiaries are not subject to the Suspended Covenants under this Indenture for any period
of time as a result of the foregoing, and on any subsequent date (the “Reversion Date”) one or both of the Rating Agencies
withdraw their Investment Grade Rating or downgrade the rating assigned to the Securities below an Investment Grade Rating, then UK Holdco
and its Restricted Subsidiaries shall thereafter again be subject to the Suspended Covenants under this Indenture with respect to future
events.

 

    -95- 

     

    

 

 

(c)           The
period of time between the occurrence of a Covenant Suspension Event and the Reversion Date is referred to as the “Suspension
Period.” Additionally, upon the occurrence of a Covenant Suspension Event, the amount of Excess Proceeds and Collateral Excess
Proceeds from Net Cash Proceeds shall be reset at zero.

 

(d)           In
the event of any such reinstatement on a Reversion Date, no action taken or omitted to be taken by UK Holdco or any of its Restricted
Subsidiaries prior to such Reversion Date (and no action taken or omitted to be taken following a Reversion Date in connection with honoring,
complying with or otherwise performing or consummating any contractual commitments or obligations entered into during a Suspension Period)
shall give rise to a Default or Event of Default under this Indenture with respect to any Securities; provided that (1) with
respect to Restricted Payments made after any such reinstatement, the amount of Restricted Payments made shall be calculated as though
Section 4.04 had been in effect prior to, but not during, the Suspension Period; provided that no Subsidiaries may be designated
as Unrestricted Subsidiaries during the Suspension Period unless such designation would have complied with Section 4.04 as if Section 4.04
would have been in effect during such period and (2) all Indebtedness Incurred, or Disqualified Stock or Preferred Stock issued,
during the Suspension Period shall be classified as having been Incurred or issued pursuant to Section 4.03(b)(iii). In addition,
for purposes of Section 4.07, all agreements and arrangements entered into by the Issuer and any Restricted Subsidiary with an Affiliate
of UK Holdco during the Suspension Period prior to such Reversion Date shall be deemed to have been entered into on or prior to the Completion
Date, and for purposes of Section 4.05, all contracts entered into during the Suspension Period prior to such Reversion Date that
contain any of the restrictions contemplated by such Section 4.05 shall be deemed to have been existing on the Completion Date.

 

(e)           The
Issuer shall provide an Officer’s Certificate to the Trustee indicating the occurrence of any Covenant Suspension Event or Reversion
Date. The Trustee will have no obligation to (i) independently determine or verify if such events have occurred, (ii) make
any determination regarding the impact of actions taken during the Suspension Period on UK Holdco and its Subsidiaries’ future
compliance with their covenants or (iii) notify the Holders of any Covenant Suspension Event or Reversion Date.

(x) the Fixed Charge Coverage Ratio for the Successor Holdings Guarantor and its Restricted Subsidiaries would not be less than
such ratio for UK Holdco and its Restricted Subsidiaries immediately prior to such transaction or (y) the Consolidated Total Debt

(v)           Holdings
shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel (which may be subject to customary assumptions
and exclusions), each stating that such consolidation, merger or transfer and such supplemental indentures (if any) comply with, and
are permitted by, this Indenture and that this Indenture constitutes a valid and binding obligation of the Successor Holdings Guarantor;
and

 

(vi)          to
the extent any assets of the Person which is merged or consolidated with or into Holdings are assets of the type which would constitute
Collateral under the Security Documents, Holdings or the Successor Holdings Guarantor, as applicable, will take such action, if any,
as may be reasonably necessary to cause such property and assets to be made subject to the Lien of the applicable Security Documents
in the manner and to the extent required in this Indenture or the applicable Security Documents and shall take all reasonably necessary
action so that such Lien is perfected to the extent required by the applicable Security Documents.

 

Subject to certain limitations described in this
Indenture, the Successor Holdings Guarantor will succeed to, and be substituted for, Holdings under this Indenture and the Guarantee

Issuer is the surviving corporation), or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its
properties or assets (determined on a consolidated basis), in one or more related transactions, to any Person unless:

 

(i)            the

or to which such sale, assignment, transfer, lease, conveyance or other disposition shall have been made is a corporation, partnership
or limited liability company organized or existing under the laws of the United States, any state thereof or the District of Columbia

(ii)           the
Successor Company (if other than the Issuer) expressly assumes all the obligations of the Issuer under this Indenture, the Securities
and the applicable Security Documents pursuant to supplemental indentures or other documents or instruments;

after giving effect to such transaction (and treating any Indebtedness that becomes an obligation of the Successor Company or any of
its Restricted Subsidiaries as a result of such transaction as having been Incurred by the Successor Company or such Restricted Subsidiary
at the time of such transaction) no Default or Event of Default shall have occurred and be continuing;

 

    	-102-

     

    

 

(iv)           immediately
after giving pro forma effect to such transaction, as if such transaction had occurred at the beginning of the applicable four-quarter
period, either

 

(A)           the
Successor Company would be permitted to Incur at least $1.00 of additional Indebtedness as Ratio Debt; or

with, and are permitted by, this Indenture and that this Indenture constitutes a valid and binding obligation of the Successor Company;
and

 

(vi)          to
the extent any assets of the Person which is merged or consolidated with or into the Issuer are assets of the type which would constitute
Collateral under the Security Documents, the Issuer or Successor Company, as applicable, will take such action, if any, as may be reasonably
necessary to cause such property and assets to be made subject to the Lien of the applicable Security Documents in the manner and to
the extent required in this Indenture or the applicable Security Documents and shall take all reasonably necessary action so that such
Lien is perfected to the extent required by the applicable Security Documents.

 

The Successor Company (if other than the Issuer)
shall succeed to, and be substituted for, the Issuer under this Indenture and the Securities, and in such event, the Issuer shall automatically
be released and discharged from its obligations under this Indenture and the Securities. Notwithstanding the foregoing Sections 5.01(c)(iii) and
(iv), (x) the Issuer may consolidate with, merge into or sell, assign, transfer, lease, convey or otherwise dispose of all or part
of its properties and assets to Holdings, UK Holdco or any Restricted Subsidiary and (y) the Issuer may merge or consolidate with
an Affiliate incorporated or organized solely for the purpose of reincorporating or reorganizing the Issuer in a state of the United
States, the District of Columbia, any territory of the United States, Luxembourg or the United Kingdom, so long as, in each case, the
amount of Indebtedness of UK Holdco and its Restricted Subsidiaries is not increased thereby (any transaction described in this sentence,
a “Specified Merger/Transfer Transaction”).

 

(d)           Subject
to the provisions of Section 11.02(d), which govern the release of a Guarantee upon the sale or disposition of a Guarantor, each
Subsidiary Guarantor shall not, and UK Holdco shall not permit any Subsidiary Guarantor to, consolidate or merge with or into or wind
up into (whether or not such Subsidiary Guarantor is the surviving corporation), or sell, assign, transfer, lease, convey or otherwise
dispose of all or substantially all of its properties or assets in one or more related transactions to, any Person (herein called the
 “Successor Guarantor”) unless:

 

(i)            the
surviving company (or company to which assets are transferred) in such liquidation, merger, sale, transfer or other disposition is the
Issuer or a Guarantor; or

 

    	-103-

     

    

 

(ii)           (A)          such
sale or disposition or consolidation or merger is not in violation of Section 4.06;

 

(B)           immediately
after giving effect to such transaction (and treating any Indebtedness that becomes an obligation of the Successor Guarantor or any of
its Subsidiaries as a result of such transaction as having been Incurred by the Successor Guarantor or such Subsidiary at the time of
such transaction) no Default or Event of Default shall have occurred and be continuing;

 

(C)           the
Successor Guarantor (if other than such Subsidiary Guarantor) shall have delivered or caused to be delivered to the Trustee an Officer’s
Certificate and an Opinion of Counsel (which may be subject to customary assumptions and exclusions), stating that such consolidation,
merger or transfer and such supplemental indenture complies with this Indenture and that this Indenture constitutes a valid and binding
obligation of the Successor Guarantor;

 

(D)           the
Successor Guarantor expressly assumes all the obligations of such Subsidiary Guarantor under this Indenture, the Securities and the applicable
Security Documents, pursuant to a supplemental indenture; and

 

(E)           to
the extent any assets of the Person which is merged or consolidated with or into the Subsidiary Guarantor are assets of the type which

such action, if any, as may be reasonably necessary to cause such property and assets to be made subject to the Lien of the applicable
Security Documents in the manner and to the extent required in this Indenture or the applicable Security Documents and shall take all
reasonably necessary action so that such Lien is perfected to the extent required by the applicable Security Documents.

 

(F)           The
Successor Guarantor shall succeed to, and be substituted for, such Subsidiary Guarantor under this Indenture and such Subsidiary Guarantor’s
Guarantee, and such Subsidiary Guarantor will automatically be released and discharged from its obligations under this Indenture and
such Subsidiary Guarantor’s Guarantee.

 

(e)           Notwithstanding
the requirements set forth in Section 5.01(d), (1) a Subsidiary Guarantor may merge or consolidate with an Affiliate incorporated
or organized solely for the purpose of reincorporating or reorganizing such Subsidiary Guarantor in a state of the United States, the
District of Columbia, any territory of the United States, Luxembourg or the United Kingdom, so long as the amount of Indebtedness of
the Subsidiary Guarantor is not increased thereby, (2) a Subsidiary Guarantor may merge or consolidate with or transfer all or part
of its properties or assets to another Guarantor or the Issuer, and (3) a Subsidiary Guarantor may convert into a corporation, partnership,

DEFAULTS AND REMEDIES

 

SECTION 6.01.     Events
of Default. An “Event of Default” occurs if:

default occurs in any payment of interest, if any, on any Security when the same becomes due and payable, and such default continues
for a period of 30 days,

 

(b)           a
default occurs in the payment of principal or premium, if any, of any Security when due at its Stated Maturity, upon optional redemption,
upon required repurchase, upon declaration or otherwise,

 

(c)           Holdings,
UK Holdco or any Restricted Subsidiary of UK Holdco fails to comply with any of its agreements contained in the Securities or this Indenture

receipt of a related written Notice of Default as specified below,

 

(d)           Holdings,
UK Holdco, the Issuer or any Significant Subsidiary of UK Holdco fails to pay any Indebtedness (other than Indebtedness owing to Holdings,
UK Holdco or a Restricted Subsidiary) within any applicable grace period after final maturity or the acceleration of any such Indebtedness
by the holders thereof because of a default, in each case, if the total amount of such Indebtedness unpaid or accelerated exceeds $125.0 million
or its foreign currency equivalent,

 

(e)           Holdings,

the winding up or liquidation of Holdings, UK Holdco, the Issuer or any Significant Subsidiary of UK Holdco;

 

    	-105-

     

    

 

or any similar relief is granted under any foreign laws
and the order or decree remains unstayed and in effect for 90 days,

 

(g)           Holdings,
UK Holdco, the Issuer or any Significant Subsidiary of UK Holdco fails to pay final and non-appealable judgments aggregating in excess
of $125.0 million or its foreign currency equivalent (net of any amounts which are covered by enforceable insurance policies issued
by solvent carriers), which judgments are not discharged, waived or stayed for a period of 60 days following the entry thereof and, in
the event such judgment is covered by insurance, an enforcement proceeding has been commenced by any creditor upon such judgment or decree
which is not promptly stayed,

 

(h)           the
Guarantee of Holdings, UK Holdco or a Significant Subsidiary of UK Holdco ceases to be in full force and effect in any material respect
(except as contemplated by the terms thereof) or any such Guarantor denies or disaffirms its obligations under this Indenture, any Guarantee
or any Security Document and such Default continues for 21 days after written notice of such Default shall have been given to the Trustee,

 

(i)            (x) the
Liens created by the Security Documents shall at any time not constitute a valid and perfected Lien on any portion of the Collateral

Documents) other than (A) in accordance with the terms of the relevant Security Document and this Indenture, (B) the satisfaction
in full of all Obligations under this Indenture or (C) any loss of perfection that results from the failure of the Collateral Agent,
the Credit Agreement Collateral Agent or the representative for any other series of First Priority Lien Obligations to maintain possession
of certificates delivered to it representing securities pledged under the Security Documents and (y) such Default continues for
30 days after receipt of written notice given by the Trustee or the Holders of not less than 30% in aggregate principal amount of the
then outstanding Securities,

 

(j)            Holdings,
UK Holdco, the Issuer or any Subsidiary Guarantor shall assert, in any pleading in any court of competent jurisdiction, that any security
interest in any Security Document is invalid or unenforceable, or

 

(k)           the
Issuer fails to consummate the Special Mandatory Redemption to the extent required pursuant to Section 3.12(c).

 

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

 

The term “Bankruptcy Law” means
any law relating to bankruptcy, insolvency, receivership, winding-up, liquidation, reorganization or relief of debtors or any amendment
to, succession to or change in any such law, including, without limitation (i) bankruptcy laws of Luxembourg, (ii) Title 11,
United States Code (as amended from time to time), (iii) the Insolvency Act of 1986 of the United Kingdom (as amended from time
to time), or (iv) any similar law for the relief of debtors in any other jurisdiction applicable to Holdings, UK Holdco, the Issuer
or any Significant Subsidiary of UK Holdco. The term “Custodian” means any receiver, trustee, assignee, liquidator,
custodian, administrator, administrative receiver, manager, or similar official under any Bankruptcy Law.

 

    	-106-

     

    

 

A Default under clauses (c), (d), (g) and
(i) above shall not constitute an Event of Default until the Trustee notifies the Issuer in writing or the Holders of at least 30%
of the aggregate principal amount of the outstanding Securities notify the Issuer and the Trustee in writing of the Default and the Issuer
does not cure such Default within the time specified in clauses (c), (d), (g) and (i) above, as applicable, after receipt
of such notice. provided that a notice of Default must specify the Default, demand that it be remediated and state that such notice
is a “Notice of Default.” A notice of Default may not be given with respect to any action taken, and reported publicly or
to Holders of the Securities, more than two years prior to such notice of Default. Any notice of Default, notice of acceleration or instruction
to the Trustee or the Collateral Agent, as applicable, to provide a notice of Default, notice of acceleration or take any other action
(a “Noteholder Direction”) provided by any one or more Holders (each a “Directing Holder”) must
be accompanied by a written representation from each such Holder delivered to the Issuer and the Trustee or the Collateral Agent, as
applicable, that such Holder is not (or, in the case such holder is DTC or its nominee, that such Holder is being instructed solely by
beneficial owners that are not) Net Short (a “Position Representation”), which representation, in the case of a Noteholder
Direction relating to the delivery of a notice of Default (a “Default Direction”) shall be deemed a continuing representation
until the resulting Event of Default is cured or otherwise ceases to exist or the Securities are accelerated. In addition, each Directing
Holder is deemed, at the time of providing a Noteholder Direction, to covenant to provide the Issuer with such other information as the
Issuer may reasonably request from time to time in order to verify the accuracy of such Holder’s Position Representation within
five Business Days of request therefor (a “Verification Covenant”). In any case in which the holder is DTC or its
nominee, any Position Representation or Verification Covenant required hereunder shall be provided by the beneficial owner of the Securities
in lieu of DTC or its nominee and DTC shall be entitled to conclusively rely on such Position Representation and Verification Covenant
in delivering its direction to the Trustee or the Collateral Agent, as applicable.

 

If, following the delivery of a Noteholder Direction,
but prior to acceleration of the Securities, the Issuer determines in good faith that there is a reasonable basis to believe a Directing
Holder was, at any relevant time, in breach of its Position Representation and provides to the Trustee an Officer’s Certificate
stating that the Issuer has initiated litigation with a court of competent jurisdiction seeking a determination that such Directing Holder
was, at such time, in breach of its Position Representation, and seeking to invalidate any Default, Event of Default or acceleration
(or notice thereof) that resulted from the applicable Noteholder Direction, the cure period with respect to such Default shall be automatically
stayed and the cure period with respect to such Event of Default shall be automatically reinstituted and any remedy stayed pending a
final and non-appealable determination of a court of competent jurisdiction on such matter if, without the participation of such Holder,
the percentage of Securities held by the remaining Holders that provided such Noteholder Direction would have been insufficient to validly
provide such Noteholder Direction. If, following the delivery of a Noteholder Direction, but prior to acceleration of the Securities,
the Issuer provides to the Trustee an Officer’s Certificate stating that a Directing Holder failed to satisfy its Verification
Covenant, the cure period with respect to such Default shall be automatically stayed and the cure period with respect to any Event of
Default that resulted from the applicable Noteholder Direction shall be automatically reinstituted and any remedy stayed pending satisfaction
of such Verification Covenant. Any breach of the Position Representation shall result in such Holder’s participation in such Noteholder
Direction being disregarded; and, if, without the participation of such Holder, the percentage of Securities held by the remaining Holders
that provided such Noteholder Direction would have been insufficient to validly provide such Noteholder Direction, such Noteholder Direction
shall be void ab initio (other than any indemnity such Directing Holder may have offered the Trustee and the Collateral Agent,
as applicable), with the effect that such Event of Default shall be deemed never to have occurred, any acceleration voided and the Trustee
and the Collateral Agent, as applicable, shall be deemed not to have received such Noteholder Direction or any notice of such Default
or Event of Default.

 

    	-107-

     

    

 

Notwithstanding anything in the preceding two paragraphs
to the contrary, any Noteholder Direction delivered to the Trustee in connection with a Default under clauses (c), (d), (g), (i) or
(k), during the pendency of an Event of Default under clauses (e) or (f) as a result of proceeding under Bankruptcy Law shall
not require compliance with the two immediately preceding paragraphs.

  

For the avoidance of doubt, each of the Trustee
and the Collateral Agent shall be entitled to conclusively rely on any Noteholder Direction delivered to it in accordance with the Indenture,
shall have no duty to inquire as to or investigate the accuracy of any Position Representation, enforce compliance with any Verification
Covenant, verify any statements in any Officer’s Certificate delivered to it, or otherwise make calculations, investigations or
determinations with respect to Derivative Instruments, Net Shorts, Long Derivative Instruments, Short Derivative Instruments or otherwise.
Neither the Trustee nor the Collateral Agent shall have any liability to the Issuer, any Holder or any other Person in acting in good
faith on a Noteholder Direction.

 

The Issuer shall deliver to the Trustee, within
30 days after the occurrence thereof, written notice of any event which is, or with the giving of notice or the lapse of time or both
would become, an Event of Default, its status and what action the Issuer is taking or proposes to take with respect thereto.

 

Any time period in the Indenture to cure any actual
or alleged Default or Event of Default may be extended or stayed by a court of competent jurisdiction.

 

SECTION 6.02.     Acceleration.
If an Event of Default (other than an Event of Default specified in Section 6.01(e) or (f) with respect to the Issuer)
occurs and is continuing, the Trustee by written notice to the Issuer or the Holders of at least 30% of the aggregate principal amount
of outstanding Securities by written notice to the Issuer and the Trustee, may declare the principal of, premium, if any, and accrued
but unpaid interest, if any, on all the Securities to be due and payable. Upon such a declaration, such principal and interest, if any,
shall be due and payable immediately. If an Event of Default specified in Section 6.01(e) or (f) with respect to the Issuer
occurs, the principal of, premium, if any, and interest on all the Securities shall ipso facto become and be immediately due and payable
without any declaration or other act on the part of the Trustee or any Holders. The Holders of a majority in principal amount of the
outstanding Securities by notice to the Trustee may rescind an acceleration and its consequences if the rescission would not conflict
with any judgment or decree and if all existing Events of Default have been cured or waived except nonpayment of principal or interest
that has become due solely because of acceleration. No such rescission shall affect any subsequent Default or impair any right consequent
thereto.

 

In the event of any Event of Default specified in
Section 6.01(d), such Event of Default and all consequences thereof (including, without limitation, the declaration of acceleration
of the Securities) shall be annulled, waived and rescinded, automatically and without any action by the Trustee or the Holders, if within
20 days after such Event of Default arose the Issuer delivers an Officer’s Certificate to the Trustee stating that (x) the
Indebtedness or guarantee that is the basis for such Event of Default has been discharged or (y) the holders thereof have rescinded
or waived the acceleration, default, notice or action (as the case may be) giving rise to such Event of Default or (z) the default
or acceleration that is the basis for such Event of Default has been cured or waived, it being understood that in no event shall an acceleration
of the principal amount of the Securities as described above be annulled, waived or rescinded upon the happening of any such events.

 

    	-108-

     

    

 

SECTION 6.03.     Other
Remedies. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy at law or in equity to collect
the payment of principal of or interest on the Securities or to enforce the performance of any provision of the Securities or this Indenture.

 

The Trustee may maintain a proceeding even if it
does not possess any of the Securities or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder
in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or
acquiescence in the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative to the extent
permitted by law.

 

SECTION 6.04.     Waiver
of Past Defaults. Provided the Securities are not then due and payable by reason of a declaration of acceleration, the Holders of
a majority in principal amount of the Securities by notice to the Trustee may waive an existing Default or Event of Default and its consequences
except (a) a Default or Event of Default in the payment of the principal of or interest on a Security or (b) a Default or Event
of Default in respect of a provision that under Section 9.02 cannot be amended without the consent of each Holder affected. When
a Default is waived, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured
for every purpose of this Indenture and the Security Documents, but no such waiver shall extend to any subsequent or other Default or
impair any consequent right.

 

SECTION 6.05.     Control
by Majority. The Holders of a majority in principal amount of the Securities then outstanding may direct the time, method and place
of conducting any proceeding for any remedy available to the Trustee or the Collateral Agent or of exercising any trust or power conferred
on the Trustee or the Collateral Agent. However, the Trustee or the Collateral Agent, as applicable, may refuse to follow any direction
that conflicts with law or this Indenture or, subject to Section 7.01, that the Trustee or the Collateral Agent determines is unduly
prejudicial to the rights of any other Holder (it being understood that neither the Trustee nor the Collateral Agent has an affirmative
duty to ascertain whether or not any action or forbearance is unduly prejudicial to such Holders) or that would involve Trustee or the
Collateral Agent in personal liability; provided, however, that each of the Trustee and or the Collateral Agent may take
any other action deemed proper by the Trustee or the Collateral Agent, as applicable, that is not inconsistent with such direction. Prior
to taking any action under this Indenture, the Trustee or the Collateral Agent, as applicable, shall be entitled to indemnification and/or
security (which may include pre-funding) satisfactory to each of them against all losses, liabilities and expenses caused by taking or
not taking such action.

 

SECTION 6.06.     Limitation
on Suits.

 

(a)           Except
to enforce the right to receive payment of principal, premium, if any, or interest when due, no Holder may pursue any remedy with respect
to this Indenture or the Securities unless:

 

(i)            the
Holder gives to the Trustee written notice stating that an Event of Default is continuing;

 

(ii)           the
Holders of at least 30% of the aggregate principal amount of the Securities then outstanding make a written request to the Trustee to
pursue the remedy;

 

(iii)          such
Holder or Holders offer, and if required, provide to the Trustee security and/or indemnity (which may include pre-funding) satisfactory
to it against any loss, liability or expense;

 

    	-109-

     

    

 

(iv)          the
Trustee does not comply with the request within 60 days after receipt of the request and the offer of security or indemnity; and

 

(v)           the
Holders of a majority in principal amount of the outstanding Securities do not give the Trustee a direction inconsistent with the request
during such 60-day period.

 

(b)           A
Holder may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over another Holder
(it being understood that the Trustee has no affirmative duty to ascertain whether or not such actions are unduly prejudicial to such
Holders).

 

SECTION 6.07.     Rights
of the Holders to Receive Payment. Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment
of principal of and interest on the Securities held by such Holder, on or after the respective due dates expressed or provided for in
the Securities, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or
affected without the consent of such Holder; provided that a Holder shall not have the right to institute any such suit for the
enforcement of payment if and to the extent that the institution or prosecution thereof or the entry of judgment therein would, under
applicable law, result in the surrender, impairment, waiver or loss of the Lien of this Indenture upon any property subject to such Lien.

 

SECTION 6.08.     Collection
Suit by Trustee. If an Event of Default specified in Section 6.01(a) or (b) occurs and is continuing, the Trustee
may recover judgment in its own name and as trustee of an express trust against the Issuer or any other obligor on the Securities for
the whole amount then due and owing (together with interest on overdue principal and (to the extent lawful) on any unpaid interest at
the rate provided for in the Securities) and the amounts provided for in Section 7.06.

 

SECTION 6.09.     Trustee
May File Proofs of Claim. The Trustee may file such proofs of claim and other papers or documents and take such action as may
be necessary or advisable in order to have the claims of the Trustee (including any claim for reasonable compensation, expenses disbursements
and advances of the Trustee and Collateral Agent (including counsel, accountants, experts or such other professionals as the Trustee
deems reasonably necessary, advisable or appropriate)) and the Holders allowed in any judicial proceedings relative to the Issuer or
any Guarantor, their creditors or their property, shall be entitled to participate as a member, voting or otherwise, of any official
committee of creditors appointed in such matters and, unless prohibited by law or applicable regulations, may vote on behalf of the Holders
in any election of a trustee in bankruptcy or other Person performing similar functions, and any Custodian in any such judicial proceeding
is hereby authorized by each Holder to make payments to the Trustee and, in the event that the Trustee shall consent to the making of
such payments directly to the Holders, to pay to the Trustee and Collateral Agent any amount due to them for the reasonable compensation,
expenses, disbursements and advances of the Trustee, the Collateral Agent and their agents and counsel, and any other amounts due the
Trustee and Collateral Agent under Section 7.06 and 10.08.

 

No provision of this Indenture shall be deemed to
authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement,
adjustment or composition affecting the Securities or the rights of any Holder thereof or to authorize the Trustee to vote in respect
of the claim of any Holder in any such proceeding.

 

SECTION 6.10.     Priorities.
Subject to the First Lien Intercreditor Agreement and the Notes Documents, if the Trustee collects any money or property pursuant to
this Article 6 (including upon exercise of remedies with respect to the Collateral), it shall pay out the money or property in the
following order:

 

    	-110-

     

    

 

FIRST: to the Trustee and to the Collateral
Agent, in each case for amounts due to it under this Indenture and the Security Documents;

 

SECOND: to Holders for amounts due and
unpaid on the Securities for principal, premium, if any, and interest, ratably, without preference or priority of any kind, according
to the amounts due and payable on the Securities for principal and interest, respectively; and

 

THIRD: to the Issuer or, to the extent
the Trustee or the Collateral Agent collects any amount for any Guarantor, to such Guarantor.

 

The Trustee, upon prior written notice to the Issuer
and the Guarantors, may fix a record date and payment date for any payment to the Holders pursuant to this Section 6.10. At least
15 days before such record date, the Trustee shall send to each Holder and the Issuer a notice that states the record date, the
payment date and amount to be paid.

 

SECTION 6.11.     Undertaking
for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee or the
Collateral Agent for any action taken or omitted by it as Trustee or the Collateral Agent, a court in its discretion may require the
filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable
costs, including reasonable attorneys’ fees and expenses, against any party litigant in the suit, having due regard to the merits
and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee or
the Collateral Agent, a suit by a Holder pursuant to Section 6.07 or a suit by Holders of more than 10% in principal amount of the
Securities then outstanding.

 

SECTION 6.12.     Waiver
of Stay or Extension Laws. Neither the Issuer nor any Guarantor (to the extent it may lawfully do so) shall at any time insist upon,
or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at
any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Issuer and each Guarantor (to
the extent that it may lawfully do so) hereby expressly waive all benefit or advantage of any such law, and shall not hinder, delay or
impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as though
no such law had been enacted.

 

SECTION 6.13.     Restoration
of Rights and Remedies. If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture
and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder,
then and in every such case, subject to any determination in such proceeding, the Issuer, any Guarantor, the Trustee and the Holders
shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee
and the Holders shall continue as though no such proceeding had been instituted.

 

SECTION 6.14.     Rights
and Remedies Cumulative. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or
stolen Securities in Section 2.08 hereof, no right or remedy herein conferred upon or reserved to the Trustee, Collateral Agent
or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted
by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity
or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion
or employment of any other appropriate right or remedy.

SECTION 6.15.     Delay
or Omission Not Waiver. No delay or omission of the Trustee, Collateral Agent or of any Holder to exercise any right or remedy accruing
upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence
therein. Every right and remedy given by this Article 6 or by law to the Trustee, Collateral Agent or to the Holders may be exercised
from time to time, and as often as may be deemed expedient, by the Trustee, Collateral Agent or by the Holders, as the case may be.

TRUSTEE

 

SECTION 7.01.     Duties
of Trustee.

 

(a)           If
an Event of Default has occurred and is continuing and a Trust Officer of the Trustee has actual knowledge of such Event of Default,
the Trustee shall exercise the rights and powers vested in it by this Indenture and use the same degree of care and skill in its exercise
as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs.

 

(b)           Except
during the continuance of an Event of Default actually known to a Trust Officer of the Trustee:

 

(i)            the
Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture and no implied covenants
or obligations shall be read into this Indenture against the Trustee; and

 

(ii)           in
the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the
opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture.
However, in the case of certificates or opinions required by any provision hereof to be provided to it, the Trustee shall examine the
certificates and opinions to determine whether or not they conform to the form requirements of this Indenture (but need not confirm or
investigate the accuracy of mathematical calculations or other facts stated therein).

 

(c)           The
Trustee may not be relieved from liability for its own negligent action, its own negligent failure to act or its own willful misconduct,
except that:

 

(i)            this
Section 7.01(c) does not limit the effect of Section 7.01(b);

 

(ii)           the
Trustee shall not be liable for any error of judgment made in good faith by a Trust Officer unless it is proved that the Trustee was
negligent in ascertaining the pertinent facts;

Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received
by it pursuant to Section 6.05; and

 

    	-112-

     

    

 

(iv)          no
provision of this Indenture shall require either the Trustee or Collateral Agent to expend or risk its own funds or otherwise incur liability
in the performance of any of its duties hereunder or to take or omit to take any action under this Indenture or the Security Documents
or take any action at the request or direction of Holders if it has grounds for believing that repayment of such funds is not assured
to it or it does not receive an agreement in writing from the Holders for indemnity and/or security and/or prefunding satisfactory to
it in its discretion against any loss, liability or expense which might be incurred by it in compliance with such request or direction
nor shall the Trustee or Collateral Agent be required to do anything which is illegal or contrary to applicable laws or this Indenture.
Neither the Trustee nor the Collateral Agent will be liable to the Holders if prevented or delayed in performing any of its obligations
or discretionary functions under this Indenture or the Security Documents by reason of any present or future law applicable to it, by
any governmental or regulatory authority or by any circumstances beyond its control.

 

(d)           The
Trustee shall not be liable for interest on any money received by it except as the Trustee may agree in writing with the Issuer.

held in trust by the Trustee need not be segregated from other funds except to the extent required by law.

 

(f)            Every
provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject
to the provisions of this Section 7.01.

 

(g)           The
Trustee shall not be deemed to have notice or any knowledge of any matter (including without limitation Defaults or Events of Default)
unless a Trust Officer assigned to this Indenture and working in the Trustee’s corporate trust and agency department has actual
knowledge thereof or unless written notice thereof is received by the Trustee in accordance with the terms of this Indenture and such
notice clearly references the Securities, the Issuer or this Indenture.

 

(h)           The
Trustee will (save as expressly otherwise provided herein) have absolute and uncontrolled discretion as to the exercise or non-exercise
of its functions and will not be responsible for any loss, liability, cost, claim, action, demand, expense or inconvenience which may
result from their exercise or non-exercise but, whenever the Trustee is under the provisions of this Indenture or the Securities bound
to act at the request or direction of the Holders, the Trustee shall nevertheless not be so bound unless first indemnified and/or secured
and/or prefunded to its satisfaction against all actions, proceedings, claims and demands to which it may render itself liable and all
costs, charges, damages, expenses and liabilities which it may incur by so doing.

 

SECTION 7.02.     Rights
of Trustee.

 

(a)           The
Trustee may refrain from taking any action in any jurisdiction if the taking of such action in that jurisdiction would, in its opinion,
based upon legal advice in the relevant jurisdiction, be contrary to any law of that jurisdiction or, to the extent applicable, the State
of New York. Furthermore, the Trustee may also refrain from taking such action if such action would otherwise render it liable to any
person in that jurisdiction, the State of New York or if, in its opinion based upon such legal advice, it would not have the power to
take such action in that jurisdiction by virtue of any applicable law in that jurisdiction, in the State of New York or if it is determined
by any court or other competent authority in that jurisdiction, in the State of New York that it does not have such power.

 

(b)           The
Trustee may conclusively rely on and be protected in acting or refraining to act based on any document believed by it to be genuine and
to have been signed or presented by the proper person. The Trustee need not investigate any fact or matter stated in the document.

 

    	-113-

     

    

 

(c)           Before
the Trustee acts or refrains from acting, it may require an Officer’s Certificate or an Opinion of Counsel or both. The Trustee
shall not be liable for any action it takes or omits to take in good faith in reliance on the Officer’s Certificate or Opinion
of Counsel.

 

(d)           The
Trustee may act through agents and shall not be responsible for the misconduct or negligence of any agent appointed with due care.

 

(e)           The
Trustee shall not be liable for any action it takes or omits to take in good faith which it reasonably believes to be authorized or within
its rights or powers; provided, however, that the Trustee’s conduct, as applicable, does not constitute willful misconduct
or gross negligence.

 

(f)           The
Trustee may consult with counsel of its own selection at the expense of the Issuer and the advice or opinion of counsel with respect
to legal matters relating to this Indenture and the Securities shall be full and complete authorization and protection from liability
in respect of any action taken, omitted or suffered by it hereunder in good faith and in accordance with the advice or opinion of such
counsel.

 

(g)           The
Trustee shall not be bound to make any investigation into the facts or matters stated in any Officer’s Certificate, Opinion of
Counsel, resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, approval, bond, debenture,
note or other paper or document, but the Trustee, in its discretion, may each make such further inquiry or investigation into such facts
or matters as it may see fit.

 

(h)           The
Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction
of any of the Holders pursuant to this Indenture, unless such Holders shall have offered, and if requested, provided to the Trustee indemnity
and/or security (which may include pre-funding) satisfactory to the Trustee against all losses, liabilities and expenses which might
be Incurred by it in compliance with such request or direction.

 

(i)            In
the event the Trustee receives inconsistent or conflicting requests and indemnity from two or more groups of Holders, each representing
less than the requisite majority in aggregate principal amount of the Securities then outstanding, pursuant to the provisions of this
Indenture, the Trustee, in its sole discretion, may determine what action, if any, shall be taken and shall be held harmless and shall
not incur any liability for its failure to act until such inconsistency or conflict is, in its opinion, resolved, and absent willful
misconduct or negligence, the Trustee shall not be liable for acting in good faith on instructions believed by them to be genuine and
from the proper party.

 

(j)           The
Trustee shall not have any obligation or duty to monitor, determine or inquire as to compliance, and shall not be responsible or liable
for compliance with restrictions on transfer, exchange, redemption, purchase or repurchase, as applicable, of minimum denominations imposed
under this Indenture or under applicable law or regulation with respect to any transfer, exchange, redemption, purchase or repurchase,
as applicable, of any interest in any Securities, but may at its sole discretion, choose to do so.

 

(k)           The
permissive rights of the Trustee to take the actions permitted by this Indenture will not be construed as an obligation or duty to do
so.

 

(l)            Except
with respect to Section 4.01 hereof, and provided it or an affiliate of it is acting as a Paying Agent, the Trustee shall have no
duty to inquire as to the performance of UK Holdco or the Issuer with respect to the covenants contained in Article 4 hereof. The
Trustee may assume without inquiry in the absence of written notice to the contrary that UK Holdco and the Issuer are duly complying
with its obligations contained in this Indenture required to be performed and observed by it, and that no Default or Event of Default
or other event which would require repayment of the Securities has occurred.

 

    	-114-

Trustee may, in the execution and exercise of all or any of the trusts, powers, authorities and discretions vested in it by this Indenture,
delegate to any person or persons all or any of the trusts, powers, authorities and discretions vested in it by this Indenture and any
such delegation may be made upon such terms and conditions and subject to such regulations as the Trustee may think fit. The Trustee
shall not be under any obligation to supervise the activities of such delegates and shall not be responsible for the misconduct or negligence
of such delegates, or for any costs, expenses, losses or liabilities of, or caused by, such delegates, provided that such delegation
of such delegates has been made with due care.

 

(n)           The
rights, privileges, protections, immunities and benefits given to the Trustee, including its right to be indemnified and/or secured (including
by way of pre-funding) are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, including as the
Collateral Agent and to each agent, any custodian and any other Person employed to act hereunder. The Trustee shall not be liable for
acting in good faith or instructions believed to be genuine and from the proper party.

 

(o)           In
no event shall the Trustee, including as the Paying Agent, Registrar or Collateral Agent or in any other capacity hereunder, be liable
under or in connection with this Indenture for indirect, special, incidental, punitive or consequential losses or damages of any kind
whatsoever, including but not limited to lost profits, whether or not foreseeable, even if the Trustee, including as the Paying Agent,
Registrar, Collateral Agent or in any other capacity hereunder has been advised of the possibility thereof and regardless of the form
of action in which such damages are sought.

 

(p)           The
Trustee may request that the Issuer deliver a certificate setting forth the names of individuals and/or titles of officers authorized
at such time to take specified actions pursuant to this Indenture.

Trustee shall not be required to give any bond or surety in respect of the performance of its powers and duties hereunder.

 

SECTION 7.03.     Individual
Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise
deal with and collect obligations owed to it by the Issuer or its Affiliates with the same rights it would have if it were not Trustee.
Any Paying Agent or Registrar may do the same with like rights.

 

SECTION 7.04.     Trustee’s
Disclaimer. The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture,
any Guarantee, the First Lien Intercreditor Agreement, the Security Documents, the Escrow Agreement or the Securities, it shall not be
accountable for the Issuer’s use of the proceeds from the Securities, it shall not be responsible for any statement of the Issuer
or any Guarantor in this Indenture, the First Lien Intercreditor Agreement, the Security Documents, the Escrow Agreement or in any document
issued in connection with the sale of the Securities or in the Securities other than the Trustee’s certificate of authentication,
and it shall not be responsible for and makes no representations as to the genuineness, enforceability, collectability, value, sufficiency,
location or existence of any Collateral, or the validity, effectiveness, enforceability, sufficiency, extent, perfection or priority
of any Lien therein. The Trustee shall not be charged with knowledge of any Default or Event of Default or of the identity of any Significant
Subsidiary unless either (a) a Trust Officer shall have actual knowledge thereof or (b) the Trustee shall have received written
notice thereof in accordance with Section 12.02 from the Issuer, any Guarantor or any Holder, and such notice references the Securities
and this Indenture.

 

    	-115-

     

    

 

 

SECTION 7.05.     Notice
of Defaults. If a Default or Event of Default occurs and is continuing and if a Trust Officer has actual knowledge thereof, the Trustee
shall mail by first-class mail to each Holder at the address set forth in the register, notice of the Default or Event of Default within
90 days after it is actually known to a Trust Officer. Except in the case of a Default or Event of Default in payment of principal
of, premium (if any), interest on any Securities (including payments pursuant to the optional redemption or required repurchase provisions
of such Securities), the Trustee may withhold the notice if and so long as the Trustee in good faith determines that withholding the
notice is in the interests of Holders.

 

SECTION 7.06.     Compensation
and Indemnity. The Issuer, or, upon the failure of the Issuer to pay, each Guarantor (if any), jointly and severally (subject to
the conditions set forth in Article 11), shall pay to the Trustee from time to time compensation for its services as agreed to in
writing. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Issuer
shall reimburse the Trustee upon request for all reasonable out-of-pocket expenses Incurred or made by it, including costs of collection,
in addition to the compensation for its services. Such expenses shall include the reasonable compensation and expenses, disbursements
and advances of the Trustee’s agents, counsel, accountants and experts. The Issuer and each Guarantor, jointly and severally shall
indemnify the Trustee against any and all loss, liability, claim, damage or expense (including reasonable attorneys’ fees and expenses)
Incurred by or in connection with the acceptance or administration of this Indenture and the other Notes Documents and the performance
of its duties hereunder and thereunder, including the costs and expenses of enforcing this Indenture or Guarantee against the Issuer
or a Guarantor (including this Section 7.06) and defending itself against or investigating any claim (whether asserted by the Issuer,
any Guarantor, any Holder or any other Person). The Trustee shall notify the Issuer of any claim for which it may seek indemnity promptly
upon obtaining actual knowledge thereof; provided, however, that any failure so to notify the Issuer shall not relieve
the Issuer or any Guarantor of its indemnity obligations hereunder. The Issuer shall defend the claim and the Trustee shall provide reasonable
cooperation at the Issuer’s expense in the defense. The Trustee may have separate counsel and the Issuer and the Guarantors, as
applicable, shall pay the reasonable fees and expenses of such counsel; provided, however, that the Issuer shall not be
required to pay such fees and expenses if it assumes the Trustee’s defense and, in the Trustee’s reasonable judgment, there
is no conflict of interest between the Issuer or the Guarantors, as applicable, and the Trustee in connection with such defense. The
Issuer need not reimburse any expense or indemnify against any loss, liability or expense Incurred by an indemnified party through such
party’s own willful misconduct, gross negligence or fraud as determined by a final order of a court of competent jurisdiction.

 

To secure the Issuer’s and the Guarantors’
payment obligations in this Section 7.06, the Trustee shall have a Lien prior to the Securities on all money or property held or
collected by the Trustee other than money or property held in trust to pay principal of and interest on particular Securities.

 

The Issuer’s and the Guarantors’ payment
obligations pursuant to this Section 7.06 shall survive the satisfaction or discharge of this Indenture, any rejection or termination
of this Indenture under any Bankruptcy Law or the resignation or removal of the Trustee. Without prejudice to any other rights available
to the Trustee under applicable law, when the Trustee incurs expenses after the occurrence of a Default specified in Section 6.01(e) or
(f) with respect to the Issuer, the expenses are intended to constitute expenses of administration under the Bankruptcy Law.

 

For the avoidance of doubt, the rights, privileges,
protections, immunities and benefits given to the Trustee in this Section 7.06, including its right to be indemnified, are extended
to, and shall be enforceable by, the Trustee in each of its capacities hereunder, the Collateral Agent and by each agent, custodian and
other Person employed to act hereunder.

not reasonably promptly appoint a successor Trustee, or if a vacancy exists in the office of Trustee for any reason (the Trustee in such
event being referred to herein as the retiring Trustee), the Issuer shall appoint a successor Trustee within 30 days of receiving notice
of the resignation or removal of the Trustee.

 

(c)            A
successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Issuer. Thereupon the resignation

Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to the Holders. The retiring Trustee shall promptly
transfer all property held by it as Trustee to the successor Trustee (provided all sums owing to the Trustee hereunder are paid), subject
to the Lien provided for in Section 7.06.

 

(d)           If
a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee or the

the replacement of the Trustee pursuant to this Section 7.07, the Issuer’s obligations under Section 7.06 shall continue
for the benefit of the retiring Trustee. In no event shall the retiring Trustee be held responsible for the actions or inactions of the
successor trustee.

 

SECTION 7.08.     Successor
Trustee by Merger. If the Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate
trust business or assets to, another corporation or banking association, the resulting, surviving or transferee corporation without any
further act shall be the successor Trustee.

 

    -117-

     

    

 

In case at the time such successor or successors
by merger, conversion or consolidation to the Trustee shall succeed to the trusts created by this Indenture any of the Securities shall
have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor
trustee, and deliver such Securities so authenticated; and in case at that time any of the Securities shall not have been authenticated,
any successor to the Trustee may authenticate such Securities either in the name of any predecessor hereunder or in the name of the successor
to the Trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Securities or in this Indenture
provided that the certificate of the Trustee shall have.

 

SECTION 7.09.     Eligibility;
Disqualification. There shall at all times be a Trustee hereunder that is a corporation organized and doing business under the laws
of the United States of America or of any state thereof that is authorized under such laws to exercise corporate trustee power, that
is subject to supervision or examination by federal or state authorities and that has combined capital and surplus of at least $50,000,000
as set forth in its most recent published annual report of condition.

any reason and without being responsible for any costs associated therewith by giving notice to the Issuer and the Trustee (and in the
case of resignation of the Paying Agent, the Paying Agent giving 30 days’ written notice) (waivable by the Issuer and the Trustee);
provided that in the case of resignation of the Paying Agent no such resignation shall take effect until a new Paying Agent shall
have been appointed by the Issuer to exercise the powers and undertake the duties hereby conferred and imposed upon the Paying Agent;
provided, further, that the Trustee may resign as Paying Agent or Registrar only if the Trustee also resigns as Trustee
in accordance with Section 7.07. Following receipt of a notice of resignation from any Agent, the Issuer shall promptly give notice
thereof to the Holders in accordance with Section 12.02.

 

(b)            If
any Agent gives notice of its resignation in accordance with this Section 7.10 and a replacement Agent is required and by the tenth
day before the expiration of such notice such replacement has not been duly appointed, such Agent may itself appoint as its replacement
any reputable and experienced financial institution or may petition a court of competent jurisdiction, with reasonable costs and expenses
by the Agent in relation to such petition to be paid by the Issuer. Immediately following such appointment, the Issuer shall give notice
of such appointment to the Trustee, the remaining Agents and the Holders whereupon the Issuer, the Trustee, the remaining Agents and the
replacement Agent shall acquire and become subject to the same rights and obligations between themselves as if they had entered into an
agreement in the form mutatis mutandis of this Indenture.

 

Upon its resignation becoming effective the Paying
Agent shall forthwith transfer all moneys held by it hereunder, if any, to the successor Paying Agent or, if none, the Trustee or to the
Trustee’s order, but shall have no other duties or responsibilities hereunder, and shall be entitled to the payment by the Issuer
of its remuneration for the services previously rendered hereunder and to the reimbursement of all reasonable expenses (including legal
fees) incurred in connection therewith.

defeasance option. In the event that the Issuer terminates all of its obligations under the Securities and this Indenture (with respect
to such Securities) by exercising its legal defeasance option or its covenant defeasance option, the obligations of each Guarantor under
its Guarantee of such Securities shall be terminated simultaneously with the termination of such obligations, and the Liens, if any, on
the Collateral of such Guarantor securing the Securities, will be terminated.

 

If the Issuer exercises its legal defeasance option,
payment of the Securities so defeased may not be accelerated because of an Event of Default. If the Issuer exercises its covenant defeasance
option, payment of the Securities so defeased may not be accelerated because of an Event of Default specified in Section 6.01(c) (with
respect to any Default by UK Holdco or any of its Restricted Subsidiaries with any of its obligations under Article 4 other than
Sections 4.01 and 4.12), 6.01(d), 6.01(e) (only with respect to Significant Subsidiaries of UK Holdco (other than the Issuer)), 6.01(f) (only
with respect to Significant Subsidiaries of UK Holdco (other than the Issuer)), 6.01(g), 6.01(h), 6.01(i) or 6.01(j).

 

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 has terminated.

 

    -119-

     

    

 

(d)            Notwithstanding
clause (a) above, the Issuer’s obligations in Sections 2.04, 2.05, 2.06, 2.07, 2.08, 2.09, 7.06, 7.07, 10.08(z) and
in this Article 8 shall survive until the Securities have been paid in full. Thereafter, the Issuer’s obligations in Sections
7.06, 8.05, 8.06 and 10.08(z) shall survive such satisfaction and discharge.

 

SECTION 8.02.     Conditions
to Defeasance.

 

(a)            The
Issuer may exercise its legal defeasance option or its covenant defeasance option only if:

 

(i)             the
Issuer irrevocably deposits in trust with the Trustee (or an entity designated or appointed (as agent) by it for this purpose) cash in
U.S. Dollars or U.S. Government Obligations or a combination thereof sufficient (in the opinion of an Independent Financial Advisor, which
shall be delivered to the Trustee), for the payment of principal, premium (if any) and interest on the Securities to redemption or maturity,
as the case may be;

 

(ii)           the
Issuer delivers to the Trustee an Officer’s Certificate stating that the deposit was not made with the intent of defeating, hindering,
delaying or defrauding any creditors of the Issuer or any Guarantors or others;

 

(iii)          the
deposit does not constitute a default under any other material agreement or contract relating to Indebtedness binding on the Issuer (other
than a default resulting from borrowing funds to be applied to make the deposit required to effect such legal defeasance or covenant defeasance
and any similar and simultaneous deposit relating to such other Indebtedness and, in each case, the granting of Liens in connection therewith);

 

(iv)           in
the case of the legal defeasance option, the Issuer shall have delivered to the Trustee an Opinion of Counsel (which Opinion of Counsel
may be subject to customary assumptions and exclusions) to the effect that the beneficial owners of the Securities will not recognize
income, gain or loss for U.S. federal income tax purposes as a result of such deposit and defeasance and will be subject to U.S. federal
income tax on the same amounts, in the same manner and at the same times as would have been the case if such deposit and defeasance had
not occurred, provided that such Opinion of Counsel must be based on a ruling received from, or published by, the Internal Revenue
Service or a change in applicable U.S. federal income tax law since the date of this Indenture;

 

(v)            in
the case of the covenant defeasance option, the Issuer shall have delivered to the Trustee an Opinion of Counsel (which Opinion of Counsel
may be subject to customary assumptions and exclusions) to the effect that the beneficial owners of the Securities will not recognize
income, gain or loss for U.S. federal income tax purposes as a result of such deposit and defeasance and will be subject to U.S. federal
income tax on the same amounts, in the same manner and at the same times as would have been the case if such deposit and defeasance had
not occurred; and

 

(vi)           the
Issuer delivers to the Trustee an Officer’s Certificate and an Opinion of Counsel (which Opinion of Counsel may be subject to customary
assumptions and exclusions), each stating that all conditions precedent to the defeasance and discharge of the Securities to be so defeased
and discharged as contemplated by this Article 8 have been complied with.

 

    -120-

     

    

 

Notwithstanding the foregoing, the Opinion of Counsel
required by Section 8.02(a)(iv) above need not be delivered if all Securities not theretofore delivered to the Trustee for cancellation
(x) are due and payable within one year or (y) have been or will become due and payable 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.

 

(b)            Before
or after a deposit, the Issuer may make arrangements satisfactory to the Trustee for the redemption of such Securities at a future date
in accordance with Article 3.

 

SECTION 8.03.     Application
of Trust Money. The Trustee shall hold in trust money or U.S. Government Obligations (including proceeds thereof) deposited with
it pursuant to this Article 8. It shall apply the deposited money and the money from U.S. Government Obligations through each Paying
Agent and in accordance with this Indenture to the payment of principal of and interest on the Securities so discharged or defeased.

 

SECTION 8.04.     Repayment
to Issuer. Each of the Trustee and each Paying Agent shall promptly turn over to the Issuer upon request any money or U.S. Government
Obligations held by it as provided in this Article 8 which, in the written opinion of an Independent Financial Advisor delivered
to the Trustee (which delivery shall only be required if U.S. Government Obligations have been so deposited), are in excess of the amount
thereof which would then be required to be deposited to effect an equivalent discharge or defeasance in accordance with this Article 8.

 

Subject to any applicable abandoned property law,
the Trustee and the 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 the Paying Agent shall have no further liability with respect to such monies.

 

SECTION 8.05.     Indemnity
for U.S. Government Obligations. The Issuer shall pay and shall indemnify the Trustee against any tax, fee or other charge imposed
on or assessed against deposited U.S. Government Obligations or the principal and interest received on such U.S. Government Obligations.

 

SECTION 8.06.     Reinstatement.
If the Trustee or any Paying Agent is unable to apply any money or U.S. Government Obligations in accordance with this Article 8
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 this Indenture and the Securities so discharged or defeased
shall be revived and reinstated as though no deposit had occurred pursuant to this Article 8 until such time as the Trustee or any
Paying Agent is permitted to apply all such money or U.S. Government Obligations in accordance with this Article 8; provided,
however, that, if the Issuer has made any payment of principal of or interest on, any such Securities because of the reinstatement
of its obligations, the Issuer shall be subrogated to the rights of the Holders of such Securities to receive such payment from the money
or U.S. Government Obligations held by the Trustee or any Paying Agent.

Upon the request of the Issuer accompanied by a resolution
of the Board of Directors of the Issuer authorizing the execution of any supplemental indenture entered into to effect any such amendment,
supplement or waiver, and upon receipt by the Trustee of the documents described in Section 9.06, the Trustee shall join with the
Issuer in the execution of such supplemental indenture.

 

SECTION 9.02.     With
Consent of the Holders. Except as otherwise provided in Section 9.01 or this Section 9.02, the Issuer, the Trustee, and
the Collateral Agent may amend this Indenture, the Securities, the Guarantees or the Security Documents, with the consent of the Holders
of at least a majority in aggregate principal amount of the Securities then outstanding voting as a single class (including, without
limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for the Securities) and any existing
or past default or compliance with any provisions of such documents may be waived with the consent of the Holders of a majority in principal
amount of the Securities then outstanding (including, without limitation, consents obtained in connection with the purchase of, or tender
offer or exchange offer for, Securities). However, without the consent of each Holder of an outstanding Security affected, no amendment
may (with respect to any Securities held by a non-consenting Holder):

 

(a)          reduce
the percentage of the aggregate principal amount of Securities whose Holders must consent to an amendment, supplement or waiver;

 

(b)          reduce
the rate of or extend the time for payment of interest, if any, on any Security;

 

(c)          reduce
the principal of or change the Stated Maturity of any Security;

(f)           impair

the due dates therefor or to institute suit for the enforcement of any payment on or with respect to such Holder’s Securities;

any change in Section 6.04 or 6.07 or the second sentence of this Section 9.02;

 

(h)          expressly
subordinate the Securities or any Guarantee related thereto or otherwise modify the ranking thereof to any other Indebtedness of the Issuer
or any Guarantor; or

 

(i)            modify
the Guarantees in any manner adverse to the Holders other than as contemplated in Sections 11.02(b) and (c) hereof.

 

It shall not be necessary for the consent of the
Holders under this Section 9.02 to approve the particular form of any proposed amendment, waiver or consent, but it shall be sufficient
if such consent approves the substance thereof. For the avoidance of doubt, no amendment to, or deletion of any of the covenants described
under Article 4 or Section 5.01, shall be deemed to impair or affect any rights of Holders to receive payment of principal of,
or premium, if any, or interest on, the Securities.

 

    -124-

     

    

 

Upon the request of the Issuer accompanied by a resolution

supplement or waiver, and upon receipt by the Trustee of the documents described in Section 9.06, the Trustee, subject to its rights
in Section 9.06, shall join with the Issuer in the execution of such supplemental indenture.

 

In addition, without the consent of the Holders of
at least 662⁄3% in principal amount of the Securities then outstanding, no amendment, supplement or waiver may modify any Security
Document or the provisions in this Indenture dealing with the Collateral or the Security Documents that would have the impact of releasing
all or substantially all of the Collateral from the Liens of the Security Documents (except as permitted by the terms of this Indenture
and the Security Documents) or change or alter the priority of the security interests in the Collateral.

 

SECTION 9.03.     [Reserved].

 

SECTION 9.04.     Revocation
and Effect of Consents and Waivers.

 

(a)            A
consent to an amendment or a waiver by a Holder of a Security shall bind the Holder and every subsequent Holder of that Security or portion
of the Security that evidences the same debt as the consenting Holder’s Security, even if notation of the consent or waiver is not
made on the Security. However, any such Holder or subsequent Holder may revoke the consent or waiver as to such Holder’s Security
or portion of the Security if the Trustee receives the notice of revocation before the date on which the consent or waiver becomes effective.
After an amendment or waiver becomes effective, it shall bind every Holder. An amendment or waiver becomes effective upon the (i) receipt
by the Issuer or the Trustee of consents by the Holders of the requisite principal amount of Securities, (ii) satisfaction of conditions
to effectiveness as set forth in this Indenture and any supplemental indenture hereto containing such amendment or waiver and (iii) execution
of such amendment or waiver (or supplemental indenture) by the Issuer and the Trustee.

 

(b)            The
Issuer may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to give their consent
or take any other action described above or required or permitted to be taken pursuant to this Indenture. If a record date is fixed, then
notwithstanding Section 9.04(a), those Persons who were Holders at such record date (or their duly designated proxies), and only
those Persons, shall be entitled to give such consent or to revoke any consent previously given or to take any such action, whether or
not such Persons continue to be Holders after such record date. No such consent shall be valid or effective for more than 120 days after
such record date.

 

SECTION 9.05.     Notation
on or Exchange of Securities. If an amendment, supplement or waiver changes the terms of a Security, the Issuer may require the Holder
of the Security to deliver it to the Trustee. The Trustee may place an appropriate notation on the Security regarding the changed terms
and return it to the Holder. Alternatively, if the Issuer so determines, the Issuer in exchange for the Security shall issue and upon
receipt of an Authentication Order the Trustee (or its Authenticating Agent) shall authenticate a new Security that reflects the changed
terms. Failure to make the appropriate notation or to issue a new Security shall not affect the validity of such amendment, supplement
or waiver.

 

SECTION 9.06.     Trustee
and Collateral Agent to Sign Amendments. The Trustee and Collateral Agent shall sign any amendment, supplement or waiver (including
any amended or supplemental indenture, security documents or intercreditor agreements) authorized pursuant to this Article 9 if
the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee or the Collateral
Agent, as applicable. If it does, the Trustee and the Collateral Agent, as applicable, may but need not sign it. In signing such amendment,
the Trustee and the Collateral Agent shall be entitled to receive indemnity satisfactory to each of them and shall be provided with,
and (subject to Section 7.01) shall be fully protected in relying upon, an Officer’s Certificate and Opinion of Counsel stating
that such amendment, supplement or waiver is authorized or permitted by this Indenture.

 

    -125-

     

    

 

SECTION 9.07.     Additional
Voting Terms. All Securities issued under this Indenture shall vote and consent together on all matters (as to which any of such
Securities may vote) as one class and no series of Securities will have the right to vote or consent as a separate class on any matter.

Documents.

 

(a)            Prior

otherwise, and interest on the overdue principal of, premium and interest on the Securities and performance of all other Obligations of
the Issuer and the Guarantors to the Holders or the Trustee under this Indenture, the Securities, the Guarantees and the Security Documents,
according to the terms hereunder or thereunder, shall be secured as provided in the Security Documents, which define the terms of the
Liens that secure the Notes Obligations, subject, following the Release and the grant of security interest as described below, to the
terms of the First Lien Intercreditor Agreement. The Trustee and the Issuer hereby acknowledge and agree that the Collateral Agent holds
the security interest in the Collateral for the benefit of itself, the Holders and the Trustee and pursuant to the terms of this Indenture,
the Security Documents and, following the Release and the grant of security interests as described below, the First Lien Intercreditor
Agreement. Each Holder, by accepting a Security, and each beneficial owner of an interest in a Security, consents and agrees to the terms
of the Security Documents (including the provisions providing for the possession, use, release and foreclosure of Collateral) and the
First Lien Intercreditor Agreement as the same may be in effect or may be amended from time to time in accordance with their terms and
this Indenture and the First Lien Intercreditor Agreement, and authorizes and directs the Collateral Agent to enter into the Security
Documents and the First Lien Intercreditor Agreement and to perform its obligations and exercise its rights thereunder in accordance therewith.
Subject to the Guaranty and Security Principles, following the Release and the grant of security interests as described below, the Issuer
shall deliver to the Collateral Agent copies of all documents required to be filed pursuant to the Security Documents to which the Collateral
Agent is a party, and will do or cause to be done all such acts and things as may be reasonably required by the next sentence of this
Section 10.01, to provide to the Collateral Agent the security interest in the Collateral contemplated hereby and/or by the Security
Documents or any part thereof, as from time to time constituted, so as to render the same available for the security and benefit of this
Indenture and of the Securities secured hereby, according to the intent and purposes herein expressed. Subject to the Guaranty and Security
Principles, following the Release and the grant of security interests as described below, the Issuer shall, and shall cause the Subsidiaries
of the Issuer to, take any and all actions and make all filings (including the filing of UCC financing statements, continuation statements
and amendments thereto (or analogous procedures under the applicable laws in the relevant Security Jurisdiction)) required to cause the
Security Documents to create and maintain, as security for the Notes Obligations of the Issuer and the Guarantors to the Notes Secured
Parties, a valid and enforceable perfected Lien and security interest in and on all of the Collateral (subject to the terms of the First
Lien Intercreditor Agreement, any other Acceptable Intercreditor Agreement and the Security Documents), in favor of the Collateral Agent
for the benefit of the Holders and the Trustee subject to no Liens other than Permitted Liens.

 

    -126-

     

    

 

(c)            The
security interests in the Collateral securing the Obligations under the Securities and the Guarantees (other than as set forth in the
Escrow Agreement) will not be required to be in place on the Completion Date or perfected on such date, but the Issuer will be required
to use commercially reasonable efforts to cause such security interests to be put in place no later than (x) 30 days after the Completion
Date with respect to assets located in the United States owned by the Issuer and Guarantors organized in the United States and (y) 120
days after the Completion Date with respect to other assets.

 

(d)            To
the extent any Capital Stock of any Subsidiary of Holdings would constitute Rule 3-16 Capital Stock, such Capital Stock shall automatically
be deemed not to be part of the Collateral securing the Securities and the Guarantees (but only to the extent necessary for such Subsidiary
to not be subject to the requirement to file separate financial statements of such Subsidiary with the SEC (or any other governmental
authority) pursuant to Rule 3-10 or 3-16 of Regulation S-X under the Securities Act (or any successor regulation) or any other requirement
of law in effect from time to time). In such event, the Security Documents may be amended or modified, without the consent of any Holder,
to the extent necessary to release the security interests on the Rule 3-16 Capital Stock that are so deemed to no longer constitute
part of the Collateral securing the Securities and the Guarantees.

 

(e)            Notwithstanding
any provision hereof to the contrary, the provisions of this Article 10 are qualified in their entirety by the Guaranty and Security
Principles and neither the Issuer nor any Guarantor shall be required pursuant to this Indenture or any Security Document to take any
action that would be inconsistent with the Guaranty and Security Principles.

 

SECTION 10.02.     Release
of Collateral.

(iii)           in
part, as to any asset:

 

(A)            (I) 
constituting Collateral that is sold, transferred or otherwise disposed of by the Issuer or any of the Guarantors to any Person that is
not the Issuer or a Guarantor in a transaction not prohibited by this Indenture (to the extent of the interest sold or disposed of) (but
excluding any transaction subject to Section 5.01 hereof where the recipient is required to become the obligor on the Securities
or a Guarantor hereunder),

upon release of such Guarantor as a guarantor or borrower under the Credit Agreement for any reason),

 

(C)            that
becomes an Excluded Asset, including so long as the Credit Agreement is outstanding, any asset that is not pledged to secure obligations
arising in respect of the Credit Agreement (whether pursuant to the terms of the Credit Agreement (and any related documents) or as a
result of any determination made thereunder, or by amendment, waiver or otherwise) and thereby becomes an Excluded Asset, but in each
case excluding the Escrow Account to the extent set forth in the Escrow Agreement,

 

(D)            in
the case of any Collateral subject to the First Lien Intercreditor Agreement or any other Acceptable Intercreditor Agreement, in accordance
with the terms thereof (including upon the taking of enforcement action by any representative that is “controlling” thereunder),
or

 

(E)            that
is otherwise released in accordance with, and as expressly provided for, by the terms of any Security Document,

 

(b)           With
respect to any release of Collateral or release of the Liens securing the Securities, upon receipt of an Officer’s Certificate and
an Opinion of Counsel stating that all conditions precedent under this Indenture and the Security Documents (and the First Lien Intercreditor
Agreement or any other Acceptable Intercreditor Agreement, as applicable), to such release have been met and that it is permitted for
the Trustee and/or the Collateral Agent to execute and deliver the documents requested by the Issuer in connection with such release,
and any necessary or proper instruments of termination, satisfaction, discharge or release prepared by the Issuer, the Trustee shall,
or shall cause the Collateral Agent to, execute, deliver or acknowledge (at the Issuer’s expense) such instruments or releases (whether
electronically or in writing) to evidence, and shall do or cause to be done all other acts reasonably necessary to effect, in each case
as soon as reasonably practicable, the release and discharge of any Collateral or any Liens securing the Securities permitted to be released
pursuant to this Indenture, the Security Documents, and, if applicable, the First Lien Intercreditor Agreement or such other Acceptable
Intercreditor Agreement. Neither the Trustee nor the Collateral Agent shall be liable for any such release undertaken in reliance upon
any such Officer’s Certificate or Opinion of Counsel, and notwithstanding any term hereof or in any Security Document or in the
First Lien Intercreditor Agreement or in any other Acceptable Intercreditor Agreement to the contrary, but without limiting any automatic
release provided hereunder or under any Security Document, the Trustee and the Collateral Agent shall not be under any obligation to release
any such Lien and security interest, or execute and deliver any such instrument of release, satisfaction, discharge or termination, unless
and until it receives such Officer’s Certificate and Opinion of Counsel.

SECTION 10.03.     Suits
to Protect the Collateral. Subject to the provisions of Article 7 hereof and the Security Documents and the First Lien Intercreditor
Agreement, the Trustee, without the consent of the Holders, on behalf of the Holders, following the occurrence of an Event of Default
that is continuing, may or may instruct the Collateral Agent in writing to take all actions it reasonably determines are necessary in
order to:

 

a)            enforce
any of the terms of the Security Documents; and

 

b)            collect
and receive any and all amounts payable in respect of the Obligations hereunder.

 

Subject to the provisions of the Security Documents
and the First Lien Intercreditor Agreement, if applicable, the Trustee and the Collateral Agent shall have power to institute and to maintain
such suits and proceedings as the Trustee may deem expedient to prevent any impairment of the Collateral by any acts which may be unlawful
or in violation of any of the Security Documents or this Indenture, and such suits and proceedings as the Trustee may determine to preserve
or protect its interests and the interests of the Holders in the Collateral. Nothing in this Section 10.03 shall be considered to
impose any such duty or obligation to act on the part of the Trustee or the Collateral Agent.

 

SECTION 10.04.     Authorization
of Receipt of Funds by the Trustee Under the Security Documents. Subject to the provisions of the First Lien Intercreditor Agreement
or any other Acceptable Intercreditor Agreement, if applicable, the Trustee is authorized to receive any funds for the benefit of the
Holders distributed under the Security Documents, and to make further distributions of such funds to the Holders according to the provisions
of this Indenture.

 

SECTION 10.05.     Purchaser
Protected. In no event shall any purchaser or other transferee in good faith of any property or asset purported to be released hereunder
be bound to ascertain the authority of the Collateral Agent or the Trustee to execute the release or to inquire as to the satisfaction
of any conditions required by the provisions hereof for the exercise of such authority or to see to the application of any consideration
given by such purchaser or other transferee; nor shall any purchaser or other transferee of any property, asset or rights permitted by
this Article 10 to be sold be under any obligation to ascertain or inquire into the authority of the Issuer or the applicable Guarantor
to make any such sale or other transfer.

 

SECTION 10.06.     Powers
Exercisable by Receiver or Trustee. In case the Collateral shall be in the possession of a receiver or trustee, lawfully appointed,
the powers conferred in this Article 10 upon the Issuer or a Guarantor with respect to the release, sale or other disposition of
such property or asset may be exercised by such receiver or trustee, and an instrument signed by such receiver or trustee shall be deemed
the equivalent of any similar instrument of the Issuer or a Guarantor or of any Officer or Officers thereof required by the provisions
of this Article 10; and if the Trustee shall be in the possession of the Collateral under any provision of this Indenture, then
such powers may be exercised by the Trustee.

 

SECTION 10.07.     Release
Upon Termination of the Issuer’s Obligations. In the event that the Issuer delivers to the Trustee an Officer’s Certificate
certifying that (i) payment in full of the principal of, together with accrued and unpaid interest on, the Securities and all other
Notes Obligations that are due and payable at or prior to the time such principal, together with accrued and unpaid interest, are paid
or (ii) the Issuer shall have exercised its legal defeasance option or its covenant defeasance option, in each case in accordance
with Section 8.01 and 8.02 hereof, as applicable, and an Opinion of Counsel stating that all conditions precedent to the execution
and delivery of such notice by the Trustee have been satisfied, the Trustee shall deliver to the Issuer and the Collateral Agent a notice,
in form reasonably satisfactory to the Collateral Agent, stating that the Trustee, on behalf of the Holders, disclaims and gives up any
and all rights it has in or to the Collateral solely on behalf of the Holders of the Securities without representation, warranty or recourse
(other than with respect to funds held by the Trustee pursuant to Section 8.03 hereof, as applicable), and any rights it has under
the Security Documents solely on behalf of the Holders of the Securities and upon receipt by the Collateral Agent of such notice, the
Collateral Agent shall be deemed not to hold a Lien in the Collateral on behalf of the Trustee and shall execute and deliver all documents
and do or cause to be done (at the expense of the Issuer) all acts reasonably requested by the Issuer to release and discharge such Lien
as soon as is reasonably practicable.

 

    -129-

     

    

 

SECTION 10.08.     Collateral
Agent.

 

(a)            The
Issuer and each of the Holders by acceptance of the Securities, and each beneficial owner of an interest in a Security, hereby designates
and appoints the Collateral Agent as its agent under this Indenture, the Security Documents, the First Lien Intercreditor Agreement and
any other Acceptable Intercreditor Agreement and the Issuer directs and authorizes and each of the Holders by acceptance of the Securities
hereby irrevocably authorizes the Collateral Agent to take such action on its behalf under the provisions of this Indenture, the Security
Documents and the First Lien Intercreditor Agreement and to exercise such powers and perform such duties as are expressly delegated to
the Collateral Agent by the terms of this Indenture, the Security Documents, the First Lien Intercreditor Agreement any other Acceptable
Intercreditor Agreement, and consents and agrees to the terms of the First Lien Intercreditor Agreement, each Security Document and any
other Acceptable Intercreditor Agreement, as the same may be in effect or may be amended, restated, supplemented or otherwise modified
from time to time in accordance with their respective terms or the terms of this Indenture. The Collateral Agent agrees to act as such
on the express conditions contained in this Section 10.08. The provisions of this Section 10.08 are solely for the benefit of
the Collateral Agent and none of the Trustee, any of the Holders nor any of the Grantors shall have any rights as a third party beneficiary
of any of the provisions contained herein. Each Holder agrees that any action taken by the Collateral Agent in accordance with the provision
of this Indenture, the First Lien Intercreditor Agreement any other Acceptable Intercreditor Agreement and/or the applicable Security
Documents, and the exercise by the Collateral Agent of any rights or remedies set forth herein and therein shall be authorized and binding
upon all Holders. Notwithstanding any provision to the contrary contained elsewhere in this Indenture, the Security Documents, the First
Lien Intercreditor Agreement and any other Acceptable Intercreditor Agreement, the duties of the Collateral Agent shall be ministerial
and administrative in nature, and the Collateral Agent shall not have any duties or responsibilities, except those expressly set forth
herein and in the other Notes Documents to which the Collateral Agent is a party, nor shall the Collateral Agent have or be deemed to
have any trust or other fiduciary relationship with the Trustee, any Holder or any Grantor, and no implied covenants, functions, responsibilities,
duties, obligations or liabilities shall be read into this Indenture, the Security Documents, the First Lien Intercreditor Agreement or
any other Acceptable Intercreditor Agreement or otherwise exist against the Collateral Agent. Without limiting the generality of the foregoing
sentence, the use of the term “agent” in this Indenture with reference to the Collateral Agent is not intended to connote
any fiduciary or other implied (or express) obligations arising under agency doctrine of any applicable law. Instead, such term is used
merely as a matter of market custom, and is intended to create or reflect only an administrative relationship between independent contracting
parties.

 

(b)            The
Collateral Agent may perform any of its duties under this Indenture, the Security Documents or the First Lien Intercreditor Agreement
by or through receivers, agents, employees, attorneys-in-fact or with respect to any specified Person, such Person’s Affiliates,
and the respective officers, directors, employees, agents, advisors and attorneys-in-fact of such Person and its Affiliates (a “Related
Person”), and shall be entitled to advice of counsel concerning all matters pertaining to such duties, and shall be entitled
to act upon, and shall be fully protected in taking action in reliance upon any advice or opinion given by legal counsel. The Collateral
Agent shall not be responsible for the negligence or willful misconduct of any receiver, agent, employee, attorney-in-fact or Related
Person that it selects as long as such selection was made in good faith.

 

    -130-

     

    

 

(c)            Neither
the Collateral Agent nor any of its Related Persons shall (i) be liable for any action taken or omitted to be taken by any of them
under or in connection with this Indenture or the transactions contemplated hereby (except for its own gross negligence or willful misconduct)
or under or in connection with any Security Document or the First Lien Intercreditor Agreement or any other Acceptable Intercreditor Agreement
or the transactions contemplated thereby (except for its own gross negligence or willful misconduct), or (ii) be responsible in any
manner to any of the Trustee or any Holder for any recital, statement, representation, warranty, covenant or agreement made by the Issuer
or any other Grantor or Affiliate of any Grantor, or any Officer or Related Person thereof, contained in this Indenture, or any other
Notes Documents, or in any certificate, report, statement or other document referred to or provided for in, or received by the Collateral
Agent under or in connection with, this Indenture, the Security Documents or the First Lien Intercreditor Agreement, or the validity,
effectiveness, genuineness, enforceability or sufficiency of this Indenture, the Security Documents, the First Lien Intercreditor Agreement
or any other Acceptable Intercreditor Agreement, or for any failure of any Grantor or any other party to this Indenture, the Security
Documents, the First Lien Intercreditor Agreement or any other Acceptable Intercreditor Agreement to perform its obligations hereunder
or thereunder. No Collateral Agent nor any of their respective Related Persons shall be under any obligation to the Trustee or any Holder
to ascertain or to inquire as to the observance or performance of any of the agreements contained in, or conditions of, this Indenture,
the Security Documents, the First Lien Intercreditor Agreement or any other Acceptable Intercreditor Agreement or to inspect the properties,
books, or records of any Grantor or any Grantor’s Affiliates.

 

(d)            The
Collateral Agent shall be entitled (in the absence of bad faith) to rely, and shall be fully protected in relying, upon any writing, resolution,
notice, consent, certificate, affidavit, letter, telegram, facsimile, certification, telephone message, statement, or other communication,
document or conversation (including those by telephone or e-mail) believed by it to be genuine and correct and to have been signed, sent,
or made by the proper Person or Persons, and upon advice and statements of legal counsel (including, without limitation, counsel to the
Issuer or any other Grantor), independent accountants and/or other experts and advisors selected by the Collateral Agent. No Collateral
Agent shall be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument,
opinion, report, notice, request, direction, consent, order, bond, debenture, or other paper or document. Unless otherwise expressly required
hereunder or pursuant to any Security Document, the Collateral Agent shall be fully justified in failing or refusing to take any action
under this Indenture, the Security Documents or the First Lien Intercreditor Agreement unless it shall first receive such written advice
or concurrence of the Trustee or the Holders of a majority in aggregate principal amount of the Securities as it determines and, if it
so requests, it shall first be indemnified to its satisfaction by the Holders against any and all liability and expense which may be incurred
by it by reason of taking or continuing to take any such action. The Collateral Agent shall in all cases be fully protected from claims
by any Holders in acting, or in refraining from acting, under this Indenture, the Security Documents or the First Lien Intercreditor Agreement
in accordance with a request, direction, instruction or consent of the Trustee or the Holders of a majority in aggregate principal amount
of the then outstanding Notes and such request and any action taken or failure to act pursuant thereto shall be binding upon all of the
Holders.

 

(e)            No
Collateral Agent shall be deemed to have knowledge or notice of the occurrence of any Default or Event of Default, unless a Trust Officer
of the Collateral Agent shall have received written notice from the Trustee or the Issuer referring to this Indenture, describing such
Default or Event of Default and stating that such notice is a “notice of default.” The Collateral Agent shall take such action
with respect to such Default or Event of Default as may be requested by the Trustee in accordance with Article 6 or the Holders
of a majority in aggregate principal amount of the Securities (subject to this Section 10.08).

 

    -131-

     

    

 

(f)            The
Collateral Agent may resign at any time by notice to the Trustee and the Issuer, such resignation to be effective upon the acceptance
of a successor agent to its appointment as Collateral Agent. If the Collateral Agent resigns under this Indenture, the Issuer shall appoint
a successor collateral agent. If no successor collateral agent is appointed prior to the intended effective date of the resignation of
the Collateral Agent (as stated in the notice of resignation), the Collateral Agent may appoint, after consulting with the Trustee, subject
to the consent of the Issuer (which shall not be unreasonably withheld and which shall not be required during a continuing Event of Default),
a successor collateral agent. If no successor collateral agent is appointed and consented to by the Issuer pursuant to the preceding sentence
within thirty (30) days after the intended effective date of resignation (as stated in the notice of resignation) the Collateral Agent
shall be entitled to petition a court of competent jurisdiction to appoint a successor. Upon the acceptance of its appointment as successor
collateral agent hereunder, such successor collateral agent shall succeed to all the rights, powers and duties of the retiring Collateral
Agent, and the term “Collateral Agent” shall mean such successor collateral agent, and the retiring Collateral Agent’s
appointment, powers and duties as the Collateral Agent shall be terminated. After the retiring Collateral Agent’s resignation hereunder,
the provisions of this Section 10.08 (and Section 7.06) shall continue to inure to its benefit and the retiring Collateral Agent
shall not by reason of such resignation be deemed to be released from liability as to any actions taken or omitted to be taken by it while
it was the Collateral Agent under this Indenture.

 

(g)            The
Issuer and each of the Holders by its acceptance of the Securities, and each beneficial owner of an interest in a Security, hereby authorizes
the Trustee and the Collateral Agent, respectively, to appoint co-collateral agents, sub-agents and other additional Collateral Agents
(and, in each case, appointment of such person shall be reflected in documentation, which the Trustee and the Collateral Agent are hereby
authorized to enter into) as the Collateral Agent deems necessary or appropriate. Except as otherwise explicitly provided herein or in
the Security Documents or the First Lien Intercreditor Agreement, no Collateral Agent nor any of its respective officers, directors, employees
or agents or other Related Persons shall be liable for failure to demand, collect or realize upon any of the Collateral or for any delay
in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of any other Person or to
take any other action whatsoever with regard to the Collateral or any part thereof. The Collateral Agent shall be accountable only for
amounts that it actually receives as a result of the exercise of such powers, and neither the Collateral Agent nor any of their respective
officers, directors, employees or agents shall be responsible for any act or failure to act hereunder, except for its own gross negligence
or willful misconduct.

 

(h)            The
Collateral Agent is authorized and directed to (i) enter into the Security Documents to which it is party, whether executed on or
after the Issue Date, (ii) enter into a supplement or joinder to the First Lien Intercreditor Agreement, (iii) enter into any
Acceptable Intercreditor Agreement, (iv) make the representations of the Holders set forth in the Security Documents, the First Lien
Intercreditor Agreement or any other Acceptable Intercreditor Agreement, (v) bind the Holders on the terms as set forth in the Security
Documents, the First Lien Intercreditor Agreement or any other Acceptable Intercreditor Agreement and (vi) perform and observe its
obligations under the Security Documents, the First Lien Intercreditor Agreement and any other Acceptable Intercreditor Agreement.

 

(i)            If
applicable, the Collateral Agent is each Holder’s agent for the purpose of perfecting the Holders’ security interest in assets
which, in accordance with Article 9 of the UCC can be perfected only by possession. Should the Trustee obtain possession of any such
Collateral, upon request from the Issuer, the Trustee shall notify the Collateral Agent thereof and promptly shall deliver such Collateral
to the Collateral Agent or otherwise deal with such Collateral in accordance with the Collateral Agent’s instructions; provided
that, to the extent the Trustee is the secured party in respect of any security interests granted in connection with the Escrow Agreement,
it shall act in accordance with the terms thereof and be subject to the terms of this Section 10.08 and the other applicable provisions
of this Indenture in the same manner as the Collateral Agent.

 

    -132-

     

    

  

(j)            The
Collateral Agent shall not have any obligation whatsoever to the Trustee or any of the Holders to assure that the Collateral exists or
is owned by any Grantor or is cared for, protected, or insured or has been encumbered, or that the Collateral Agent’s Liens have
been properly or sufficiently or lawfully created, perfected, protected, maintained or enforced or are entitled to any particular priority,
or to determine whether all or the Grantor’s property constituting collateral intended to be subject to the Lien and security interest
of the Security Documents has been properly and completely listed or delivered, as the case may be, or the genuineness, validity, marketability
or sufficiency thereof or title thereto, or to exercise at all or in any particular manner or under any duty of care, disclosure, or fidelity,
or to continue exercising, any of the rights, authorities, and powers granted or available to the Collateral Agent pursuant to this Indenture,
any Security Document or the First Lien Intercreditor Agreement other than pursuant to the instructions of the Trustee or the Holders
of a majority in aggregate principal amount of the Securities or as otherwise provided in the Security Documents, it being understood
and agreed that in respect of the Collateral, or any act, omission, or event related thereto, no Collateral Agent shall have any other
duty or liability whatsoever to the Trustee or any Holder or any other Collateral Agent as to any of the foregoing.

 

(k)            If
the Issuer or any Guarantor incurs any obligations in respect of First Priority Lien Obligations that is permitted by the terms of this
Indenture at any time when neither the First Lien Intercreditor Agreement nor any other intercreditor agreement in respect of the First
Priority Lien Obligations is in effect or at any time when Indebtedness constituting First Priority Lien Obligations entitled to the benefit
of such First Lien Intercreditor Agreement or other intercreditor agreement is concurrently retired, or incurs any other obligations permitted
hereunder and required to be subject to an intercreditor agreement, subject to the second paragraph of Section 9.01 hereof, the Collateral
Agent and the Trustee (as applicable) are hereby authorized and directed to enter into such intercreditor agreement provided that such
intercreditor agreement is an Acceptable Intercreditor Agreement (at the sole expense and cost of the Issuer, including legal fees and
expenses of the Collateral Agent), bind the Holders on the terms set forth therein and perform and observe its obligations thereunder.

 

(l)            If
the Issuer or any Guarantor incurs any obligations in respect of Indebtedness on which a junior lien on the Collateral is to be granted
that is permitted by the terms of this Indenture, subject to the second paragraph of Section 9.01 hereof, the Collateral Agent and
the Trustee (as applicable) are hereby authorized and directed to enter into such intercreditor agreement provided that such intercreditor
agreement is an Acceptable Intercreditor Agreement (at the sole expense and cost of the Issuer, including legal fees and expenses of the
Collateral Agent), bind the Holders on the terms set forth therein and perform and observe its obligations thereunder.

 

(m)            No
provision of this Indenture, the First Lien Intercreditor Agreement or any Security Document shall require the Collateral Agent (or the
Trustee) to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder
or thereunder or to take or omit to take any action hereunder or thereunder or take any action at the request or direction of Holders
(or the Trustee in the case of the Collateral Agent) unless it shall have first received indemnity satisfactory to the Collateral Agent
against potential costs and liabilities incurred by the Collateral Agent relating thereto. Notwithstanding anything to the contrary contained
in this Indenture, the First Lien Intercreditor Agreement or the Security Documents, in the event the Collateral Agent is entitled or
required to commence an action to foreclose or otherwise exercise its remedies to acquire control or possession of the Collateral, the
Collateral Agent shall not be required to commence any such action or exercise any remedy or to inspect or conduct any studies of any
property under the mortgages or take any such other action if the Collateral Agent has determined that it may incur personal liability
as a result of the presence at, or release on or from, the Collateral or such property, of any hazardous substances unless the Collateral
Agent has received security or indemnity from the Holders in an amount and in a form all satisfactory to the Collateral Agent in its sole
discretion, protecting the Collateral Agent from all such liability. The Collateral Agent shall at any time be entitled to cease taking
any action described in this Section 10.08(m) if it no longer reasonably deems any indemnity, security or undertaking from the
Issuer or the Holders to be sufficient.

 

    -133-

     

    

 

(n)            The
Collateral Agent (i) shall not be liable for any action taken or omitted to be taken by it in connection with this Indenture, the
First Lien Intercreditor Agreement and the Security Documents or instrument referred to herein or therein, except to the extent that any
of the foregoing are found by a final, non-appealable judgment of a court of competent jurisdiction to have resulted from its own gross
negligence or willful misconduct, (ii) shall not be liable for interest on any money received by it except as the Collateral Agent
may agree in writing with the Issuer (and money held in trust by the Collateral Agent (a) shall be held uninvested without liability
for interest, unless otherwise agreed in writing, (b) shall be held in a non-interest bearing trust account and (c) shall not
be segregated from other funds except to the extent required by law) and (iii) may consult with counsel of its selection and the
advice or opinion of such counsel as to matters of law shall be full and complete authorization and protection from liability in respect
of any action taken, omitted or suffered by it in good faith and in accordance with the advice or opinion of such counsel. The grant of
permissive rights or powers to the Collateral Agent shall not be construed to impose duties to act.

 

(o)            Neither
the Collateral Agent nor the Trustee shall be liable for delays or failures in performance resulting from acts beyond its control. Such
acts shall include but not be limited to acts of God, strikes, lockouts, riots, acts of war, epidemics, governmental regulations superimposed
after the fact, fire, communication line failures, computer viruses, power failures, earthquakes or other disasters. Neither the Collateral
Agent nor the Trustee shall be liable for any indirect, special, punitive, incidental or consequential damages (included but not limited
to lost profits) whatsoever, even if it has been informed of the likelihood thereof and regardless of the form of action.

 

(p)            The
Collateral Agent assumes no responsibility for any failure or delay in performance or any breach by the Issuer or any other Grantor under
this Indenture, the First Lien Intercreditor Agreement, any other Acceptable Intercreditor Agreement or the Security Documents. The Collateral
Agent shall not be responsible to the Holders or any other Person for any recitals, statements, information, representations or warranties
contained in any Notes Documents or in any certificate, report, statement, or other document referred to or provided for in, or received
by the Collateral Agent under or in connection with, this Indenture, the First Lien Intercreditor Agreement any other Acceptable Intercreditor
Agreement or any Security Document; the execution, validity, genuineness, effectiveness or enforceability of the First Lien Intercreditor
Agreement, any other Acceptable Intercreditor Agreement or any Security Document of any other party thereto; the genuineness, enforceability,
collectability, value, sufficiency, location or existence of any Collateral, or the validity, effectiveness, enforceability, sufficiency,
extent, perfection or priority of any Lien therein; the validity, enforceability or collectability of any Obligations; the assets, liabilities,
financial condition, results of operations, business, creditworthiness or legal status of any obligor; or for any failure of any obligor
to perform its Obligations under this Indenture, the First Lien Intercreditor Agreement, any other Acceptable Intercreditor Agreement
or any Security Document. The Collateral Agent shall not have any obligation to any Holder or any other Person to ascertain or inquire
into the existence of any Default or Event of Default, the observance or performance by any obligor of any terms of this Indenture, the
First Lien Intercreditor Agreement, any other Acceptable Intercreditor Agreement, the Credit Agreement or any Security Document, or the
satisfaction of any conditions precedent contained in this Indenture, the First Lien Intercreditor Agreement, any other Acceptable Intercreditor
Agreement or any Security Document. The Collateral Agent shall not be required to initiate or conduct any litigation or collection or
other proceeding under this Indenture, the First Lien Intercreditor Agreement, any other Acceptable Intercreditor Agreement or any Security
Document unless expressly set forth hereunder or thereunder. Without limiting its obligations as expressly set forth herein, the Collateral
Agent shall have the right at any time to seek instructions from the Holders with respect to the administration of the Notes Documents.

 

    -134-

     

    

  

(q)            The
parties hereto and the Holders hereby agree and acknowledge that the Collateral Agent shall not assume, be responsible for or otherwise
be obligated for any liabilities, claims, causes of action, suits, losses, allegations, requests, demands, penalties, fines, settlements,
damages (including foreseeable and unforeseeable), judgments, expenses and costs (including but not limited to, any remediation, corrective
action, response, removal or remedial action, or investigation, operations and maintenance or monitoring costs, for personal injury or
property damages, real or personal) of any kind whatsoever, pursuant to any environmental law as a result of this Indenture, the First
Lien Intercreditor Agreement, any other Acceptable Intercreditor Agreement, any Security Document or any actions taken pursuant hereto
or thereto. Further, the parties hereto and the Holders hereby agree and acknowledge that in the exercise of its rights under this Indenture,
the First Lien Intercreditor Agreement, any other Acceptable Intercreditor Agreement and the Security Documents, the Collateral Agent
may hold or obtain indicia of ownership primarily to protect the security interest of the Collateral Agent in the Collateral and that
any such actions taken by the Collateral Agent shall not be construed as or otherwise constitute any participation in the management of
such Collateral. However, if the Collateral Agent is required to acquire title to an asset pursuant to this Indenture which in the Collateral
Agent’s reasonable discretion may cause the Collateral Agent to be considered an “owner or operator” under the provisions
of the Comprehensive Environmental Response, Compensation and Liability Act (“CERCLA”), 42 U.S.C. §9601, et seq.,
or otherwise cause the Collateral Agent to incur liability under CERCLA or any equivalent federal, state or local law, the Collateral
Agent reserves the right, instead of taking such action, to either resign as the Collateral Agent hereunder or arrange for the transfer
of the title or control of the asset to a court-appointed receiver.

 

(r)            Upon
the receipt by the Collateral Agent of an Officer’s Certificate and an Opinion of Counsel, the Collateral Agent is hereby authorized
to execute and enter into, and shall execute and enter into, without the further consent of any Holder or the Trustee, any Security Document
to be executed after the Issue Date that is permitted to be entered into pursuant to this Indenture or the Security Documents. Such Officer’s
Certificate and an Opinion of Counsel shall (i) state that it is being delivered to the Collateral Agent pursuant to this Section 10.08(r),
and (ii) instruct the Collateral Agent to execute and enter into such Security Document and such Officer’s Certificate shall
state that such Security Document is permitted to be entered into pursuant to this Indenture. Any such execution of a Security Document
shall be at the direction and expense of the Issuer, upon delivery to the Collateral Agent of an Officer’s Certificate and an Opinion
of Counsel stating that all conditions precedent (if any) to the execution and delivery of the Security Document have been satisfied.
The Holders, by their acceptance of the Securities, hereby authorize and direct the Collateral Agent to execute such Security Documents.

 

(s)            Subject
to the provisions of the applicable Security Documents and the First Lien Intercreditor Agreement, each Holder, by acceptance of the Securities,
agrees that the Collateral Agent shall execute and deliver the First Lien Intercreditor Agreement and the Security Documents to which
it is a party and all agreements, documents and instruments incidental thereto (including any releases permitted hereunder), and act in
accordance with the terms thereof. For the avoidance of doubt, the Collateral Agent shall not be required to exercise discretion under
this Indenture, the First Lien Intercreditor Agreement or the Security Documents and shall not be required to make or give any determination,
consent, approval, request or direction without the written direction of the Holders of a majority in aggregate principal amount of the
then outstanding Notes or the Trustee, as applicable, except as otherwise expressly provided for herein or in any Security Document.

 

    -135-

     

    

 

 

(t)            After
the occurrence of an Event of Default, the Trustee may direct the Collateral Agent in connection with any action required or permitted
by this Indenture, the Security Documents or the First Lien Intercreditor Agreement.

 

(u)            The
Collateral Agent is authorized to receive any funds for the benefit of itself, the Trustee and the Holders distributed under the Security
Documents or the First Lien Intercreditor Agreement and to the extent not prohibited under the First Lien Intercreditor Agreement, for
turnover to the Trustee to make further distributions of such funds to itself, the Trustee and the Holders in accordance with the provisions
of Section 6.10 hereof and the other provisions of this Indenture.

 

(v)            Subject
to the terms of the Security Documents, in each case that the Collateral Agent may or is required hereunder or under any other Notes Document
to take any action (an “Action”), including without limitation to make any determination, to give consents, to exercise
rights, powers or remedies, to release or sell Collateral or otherwise to act hereunder or under any other Notes Document, the Collateral
Agent may seek direction from the Holders of a majority in aggregate principal amount of the then outstanding Notes. The Collateral Agent
shall not be liable with respect to any Action taken or omitted to be taken by it in accordance with the direction from the Holders of
a majority in aggregate principal amount of the then outstanding Notes. Subject to the terms of the Security Documents, if the Collateral
Agent shall request direction from the Holders of a majority in aggregate principal amount of the then outstanding Notes with respect
to any Action, the Collateral Agent shall be entitled to refrain from such Action unless and until the Collateral Agent shall have received
direction from the Holders of a majority in aggregate principal amount of the then outstanding Notes, and the Collateral Agent shall not
incur liability to any Person by reason of so refraining.

 

(w)            Notwithstanding
anything to the contrary in this Indenture or any other Notes Document, in no event shall the Collateral Agent or the Trustee be responsible
for, or have any duty or obligation with respect to, the recording, filing, registering, perfection, protection or maintenance of the
security interests or Liens intended to be created by this Indenture or the other Notes Documents (including without limitation the filing
or continuation of any UCC financing or continuation statements or similar documents or instruments (or analogous procedures under the
applicable laws in the relevant Security Jurisdiction), nor shall the Collateral Agent or the Trustee be responsible for, and neither
the Collateral Agent nor the Trustee makes any representation regarding, the validity, effectiveness or priority of any of the Security
Documents or the security interests or Liens intended to be created thereby.

 

(x)            Before
the Collateral Agent acts or refrains from acting in each case at the request or direction of the Issuer, the Guarantors or the Trustee,
it may require an Officer’s Certificate and an Opinion of Counsel. The Collateral Agent shall not be liable for any action it takes
or omits to take in good faith in reliance on such certificate or opinion.

 

(y)            Notwithstanding
anything to the contrary contained herein, the Collateral Agent shall only act pursuant to the instructions of the Holders and/or the
Trustee with respect to the Security Documents and the Collateral.

 

(z)            The
Issuer shall pay compensation to, reimburse expenses of and indemnify the Collateral Agent in accordance with Section 7.06 hereof.
Accordingly, the reference to the “Trustee” in Section 7.06 hereof shall be deemed to include the reference to the Collateral
Agent. The obligations of the Issuer and Guarantors to compensate, reimburse and indemnify the Collateral Agent shall survive the discharge
of this Indenture, termination of the Security Documents and the resignation or removal of the Collateral Agent.

SECTION 10.09.     Parallel
Debt. This Section 10.09 is included in this Indenture solely for the purpose of ensuring the validity and effect of certain
security rights governed by the laws of certain jurisdictions outside of the United States and the United Kingdom, granted pursuant to
the applicable Security Documents and, for the avoidance of doubt, shall not limit the rights and remedies provided to the Notes Secured
Parties by the other provisions hereof and of any of the other Notes Documents. In the case of any Guarantor that is located in a jurisdiction
where Parallel Debt provisions are customary or required (a “Parallel Debt Jurisdiction”), the Issuer, the Guarantors, the
Trustee and the Collateral Agent are hereby authorized to provide for Parallel Debt, in customary form (as determined by the Issuer in
its sole discretion) in a supplemental indenture with respect to such Guarantor’s Guarantee. The Trustee and the Issuer, without
the consent of any Holder, may also incorporate into this Indenture additional Parallel Debt provisions after the Issue Date as necessary
to address any assets or property located in any Parallel Debt Jurisdiction.

GUARANTEES

 

SECTION 11.01.     Guarantees.

 

(a)            Prior
to the Escrow Release Date, the Securities will not be guaranteed.

 

(b)            On
the Completion Date, and subject to the Guaranty and Security Principles, Holdings, UK Holdco and each of UK Holdco’s Restricted
Subsidiaries, in each case, that is an obligor under the Credit Agreement immediately prior to such date, will jointly and severally,
irrevocably and unconditionally, guarantee on a senior (and, upon the grant of security interests
on or after the Completion Date, secured) basis, the performance and punctual payment when due, whether at Stated Maturity, by
acceleration or otherwise, of all obligations of the Issuer under this Indenture and the Securities, whether for payment of principal
of, premium, if any, or interest on the Securities, fees, expenses, indemnification or otherwise (all such obligations guaranteed by such
Guarantors being herein called the “Guaranteed Obligations”). Each Guarantor further agrees that the Guaranteed Obligations
may be extended or renewed, in whole or in part, without notice or further assent from each such Guarantor, and that each such Guarantor
shall remain bound under this Article 11 notwithstanding any extension or renewal of any Guaranteed Obligation.

 

(c)            Each
Guarantor waives presentation to, demand of payment from and protest to the Issuer of any of the Guaranteed Obligations and also waives
notice of protest for nonpayment. Each Guarantor waives notice of any default under the Securities or the Guaranteed Obligations. The
obligations of each Guarantor hereunder shall not be affected by (i) the failure of any Holder, the Trustee or Collateral Agent to
assert any claim or demand or to enforce any right or remedy against the Issuer or any other Person under this Indenture, the Securities,
the Security Documents or any other agreement or otherwise; (ii) any extension or renewal of this Indenture, the Securities or any
other agreement; (iii) any rescission, waiver, amendment or modification of any of the terms or provisions of this Indenture, the
Securities, the Security Documents or any other agreement; (iv) the release of any security, if any, held by any Holder, the Trustee
or Collateral Agent for the Guaranteed Obligations or any Guarantor; (v) the failure of any Holder, Trustee or Collateral Agent to
exercise any right or remedy against any Other Guarantor (as defined below) of the Guaranteed Obligations; or (vi) any change in
the ownership of such Guarantor, except as provided in Section 11.02(d).

 

    	 	-137-	 

     

    

 

(d)            Except
as otherwise provided herein, each Guarantor hereby waives any right to which it may be entitled to have its obligations hereunder divided
among the Guarantors, such that such Guarantor’s obligations would be less than the full amount claimed. Each Guarantor hereby waives
any right to which it may be entitled to have the assets of the Issuer first be used and depleted as payment of the Issuer’s or
such Guarantor’s obligations hereunder prior to any amounts being claimed from or paid by such Guarantor hereunder. Each Guarantor
hereby waives any right to which it may be entitled to require that the Issuer be sued prior to an action being initiated against such
Guarantor.

 

(e)            Each
Guarantor further agrees that its Guarantee herein constitutes a guarantee of payment, performance and compliance when due (and not a
guarantee of collection) and waives any right to require that any resort be had by any Holder, the Trustee or Collateral Agent to any
security held for payment of the Guaranteed Obligations.

 

(f)            Except
as expressly set forth in Sections 8.01 and 11.02, the obligations of each Guarantor hereunder shall not be subject to any reduction,
limitation, impairment or termination for any reason, including any claim of waiver, release, surrender, alteration or compromise, and
shall not be subject to any defense of setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality
or unenforceability of the Guaranteed Obligations or otherwise. Without limiting the generality of the foregoing, the obligations of each
Guarantor herein shall not be discharged or impaired or otherwise affected by the failure of any Holder, the Trustee or Collateral Agent
to assert any claim or demand or to enforce any remedy under this Indenture, the Securities or any other agreement, by any waiver or modification
of any thereof, by any default, failure or delay, willful or otherwise, in the performance of the obligations, or by any other act or
thing or omission or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of any Guarantor
or would otherwise operate as a discharge of any Guarantor as a matter of law or equity.

 

(g)            Except
as set forth in Sections 8.01 and 11.02, each Guarantor agrees that its Guarantee shall remain in full force and effect until payment
in full of all the Guaranteed Obligations. Except as set forth in Sections 8.01 and 11.02, each Guarantor further agrees that its Guarantee
herein shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of principal
of or interest on any Guaranteed Obligation is rescinded or must otherwise be restored by any Holder, the Trustee or Collateral Agent
upon the bankruptcy or reorganization of the Issuer or otherwise.

 

(h)            In
furtherance of the foregoing and not in limitation of any other right which any Holder, the Trustee or Collateral Agent has at law or
in equity against any Guarantor by virtue hereof, upon the failure of the Issuer to pay the principal of or interest on any Guaranteed
Obligation when and as the same shall become due, whether at maturity, by acceleration, by redemption or otherwise, or to perform or comply
with any other Guaranteed Obligation, each Guarantor hereby promises to and shall, upon receipt of written demand by the Trustee, forthwith
pay, or cause to be paid, in cash, to the Trustee an amount equal to the sum of (i) the unpaid principal amount of such Guaranteed
Obligations, (ii) accrued and unpaid interest on such Guaranteed Obligations (but only to the extent not prohibited by applicable
law) and (iii) all other monetary obligations of the Issuer to the Holders and the Trustee in respect of the Guaranteed Obligations.

 

(i)            Each
Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Holders in respect of any Guaranteed Obligations
guaranteed hereby until payment in full of all Guaranteed Obligations. Each Guarantor further agrees that, as between it, on the one hand,
and the Holders and the Trustee, on the other hand, (i) the maturity of the Guaranteed Obligations guaranteed hereby may be accelerated
as provided in Article 6 for the purposes of any Guarantee herein, notwithstanding any stay, injunction or other prohibition preventing
such acceleration in respect of the Guaranteed Obligations guaranteed hereby, and (ii) in the event of any declaration of acceleration
of such Guaranteed Obligations as provided in Article 6, such Guaranteed Obligations (whether or not due and payable) shall forthwith
become due and payable by such Guarantor for the purposes of this Section 11.01.

 

    	 	-138-	 

     

    

 

(j)            Each
Guarantor also agrees to pay any and all costs and expenses (including reasonable attorneys’ fees and expenses) incurred by any
Holder, the Trustee or Collateral Agent in enforcing any rights under this Section 11.01.

 

(k)            Upon
request of the Trustee, each Guarantor shall execute and deliver such further instruments and do such further acts as may be reasonably
necessary or proper to carry out more effectively the purpose of this Indenture.

 

(l)            Any
Guarantee given by any direct or indirect parent of Holdings may be released and discharged from all obligations under this Article 11
at any time upon written notice to the Trustee from such direct or indirect parent of UK Holdco.

 

SECTION 11.02.     Limitation
on Guarantor Liability.

 

(a)            Any
term or provision of this Indenture to the contrary notwithstanding, the maximum aggregate amount of the Guaranteed Obligations guaranteed
hereunder by any Guarantor shall not exceed the maximum amount that can be hereby guaranteed by the applicable Guarantor without rendering
this Indenture or the Guarantee, as each relates to such Guarantor, voidable under applicable law relating to fraudulent conveyance or
fraudulent transfer or similar laws affecting the rights of creditors generally.

 

(b)            In
furtherance of the foregoing and to the extent applicable, a Guarantor’s liability in respect of its Guarantee shall be limited
to the extent set forth below:

 

(i)            Limitations
in Luxembourg.

 

(1)            Notwithstanding
anything to the contrary contained in this Indenture or the Securities, the aggregate obligations of any Guarantor whose registered office/place
of central administration is in Luxembourg (a “Luxembourg Guarantor”) in respect of the Issuer or any Restricted Subsidiary
which is not a direct or indirect subsidiary of such Luxembourg Guarantor shall be limited at any time to an aggregate amount not exceeding
90% of the greater of:

 

(A)            an
amount equal to the sum of the Luxembourg Guarantor’s net assets (Capitaux Propres, as referred to in annex I to the grand-ducal
regulation dated December 18, 2015 defining the form and content of the presentation of balance sheet and profit and loss account,
and enforcing the Luxembourg law dated 19 December 2002 on the register of commerce and companies, accounting and companies annual
accounts, as amended) (the “Regulation”) and its subordinated debt (dettes subordonnées), as reflected in the
financial information of the Luxembourg Guarantor as at the date of this Indenture or (as applicable) as at the date of its accession
as a Guarantor, including, without limitation, its most recently and duly approved financial statements (comptes annuels) and any
(unaudited) interim financial statements signed by its board of managers (gérants) or directors (administrateurs),
as applicable; and

 

    	 	-139-	 

     

    

 

(B)            an
amount equal to the sum of the Luxembourg Guarantor’s net assets (Capitaux Propres), as referred to in the Regulation and
its subordinated debt (dettes subordonnées), as reflected in the financial information of the Luxembourg Guarantor as at
the date the Guarantee is called, including, without limitation, its most recently and duly approved financial statements (comptes
annuels) and any (unaudited) interim financial statements signed by its board of managers (gérants).

 

(2)            The
limitation set forth at paragraph (1) above shall not apply to any amounts received under the Securities and made available, in any
form whatsoever, to such Luxembourg Guarantor or any of its direct or indirect subsidiaries.

 

(3)            Any
Guarantee by any Luxembourg Guarantor under this Section 11.02 will not extend to include any obligations or liabilities if such
inclusion would constitute a breach of the financial assistance prohibitions contained at Article 430-19 (where applicable) of the
Luxembourg act on commercial companies of 10 August 1915, as amended.

 

(ii)            Limitations
in Japan. Notwithstanding anything to the contrary contained in this Indenture, any Guarantee by any Guarantor which is incorporated
under the laws of Japan shall not be effective to the extent that it would result in violating Article 135 and 155 through 165 or
any other provisions of the Companies Act of Japan (Law No. 86 of 2005), as amended.

 

(iii)            Limitations
in the United Kingdom. Notwithstanding anything to the contrary contained in this Indenture or the Securities, this Guarantee does
not apply to any liability to the extent that it would result in such Guarantee constituting unlawful financial assistance within the
meaning of sections 678 or 679 of the United Kingdom Companies Act 2006, as amended.

 

(iv)            Limitations
Applicable to Certain Other Guarantors. Each Guarantor that as of the date of this Indenture or thereafter is incorporated, organized
or formed, as the case may be, under the laws of any jurisdiction other than those jurisdictions set forth in clauses (i) through
(iii) above (an “Other Guarantor”), and by its acceptance hereof, each Holder and the Trustee, hereby confirm
that it is the intention of all such parties that the Guarantee of an Other Guarantor does not constitute a fraudulent transfer or conveyance
for purposes of, or otherwise violate, applicable law. To effectuate the foregoing intention, each Holder and each Other Guarantor hereby
irrevocably agrees that the obligations of an Other Guarantor under its Guarantee shall be limited to the maximum amount as will, after
giving effect to all other contingent and fixed liabilities of such Other Guarantor result in the obligations of such Other Guarantor
not constituting such a fraudulent transfer or conveyance or otherwise violating applicable law and be subject to such other limitations
under applicable law as are described in the supplemental indenture.

 

(c)            Notwithstanding
anything in this Section 11.02 to the contrary, if following the date of this Indenture:

 

(i)            there
shall be any change in the laws of any of the jurisdictions set forth in clauses (i) through (iv) of Section 11.02(b);

 

(ii)            there
shall be any change in the laws under which any Other Guarantor is incorporated, organized or formed, as the case may be; or

 

    	 	-140-	 

     

    

 

(iii)            any
Person shall be required to execute a Guarantee pursuant to Section 4.10 or Section 11.01 otherwise hereunder and such Person
is incorporated, organized or formed, as the case may be, under the laws of any jurisdiction other than those in which entities are contemplated
to become Guarantors as of the date hereof, including those jurisdictions addressed in clauses (i) and (ii) of Section 11.02
and other than any jurisdiction in which a then existing Other Guarantor is incorporated, organized or formed, as the case may be, and
the Issuer shall reasonably determine that the provisions of Section 11.02(b)(iii) hereof with respect to any Other Guarantor
shall not adequately address the limitations on such Guarantee imposed by applicable law of the jurisdiction of incorporation, organization
or formation, as the case may be, of such Person;

 

(iv)            then
upon the delivery of an Officer’s Certificate, the Issuer shall be entitled to amend such clause or add such additional provisions
to such clause, as the case may be, to the extent necessary so that the Guarantee of a Guarantor does not violate applicable law.

 

(d)            A
Guarantee as to any Guarantor shall automatically terminate and be of no further force or effect and such Guarantor shall be deemed to
be unconditionally released and discharged from all obligations under this Article 11 upon the earliest to occur of:

 

(i)            except
in the case of Holdings or UK Holdco, the sale, disposition or other transfer (including through merger, dissolution or consolidation)
of the Capital Stock of such Guarantor to a Person other than Holdings, UK Holdco or a Restricted Subsidiary if after such sale, disposition
or other transfer, such Guarantor is no longer a Restricted Subsidiary, or the sale, disposition or other transfer of all or substantially
all the assets of such Guarantor, in each case, if such sale, disposition or other transfer is made in compliance with this Indenture,

 

(ii)            the
Issuer designating such Guarantor as, or such Guarantor becoming (in each case other than Holdings or UK Holdco), (i) an Unrestricted
Subsidiary in accordance with the provisions set forth under Section 4.04 and the definition of “Unrestricted Subsidiary”
or (ii) an Excluded Subsidiary in accordance with the definition of “Excluded Subsidiary” (unless such subsidiary continues
to provide a guarantee under the Credit Agreement),

 

(iii)            in
the case of any Restricted Subsidiary that is required to guarantee the Securities pursuant to Section 4.10, the release or discharge
of the obligation by such Restricted Subsidiary of Indebtedness of UK Holdco or any Restricted Subsidiary or the repayment of the Indebtedness
or Disqualified Stock, in each case, which resulted in the obligation to guarantee the Securities, except if a release or discharge is
by or as a result of payment in connection with the enforcement of remedies under such other obligation and a Default or Event of Default
would occur thereby,

 

(iv)            the
Issuer’s exercise of its legal defeasance option or covenant defeasance option as described under Section 8.01 or if the Issuer’s
obligations under this Indenture are discharged in accordance with the terms of this Indenture,

 

(v)            the
merger or consolidation of such Guarantor with and into the Issuer or another Guarantor that is the surviving Person in such merger or
consolidation, or upon the liquidation or dissolution of such Guarantor following the transfer of all or substantially all of its assets
to the Issuer or another Guarantor,

 

    	 	-141-

or any other Guarantor, other than in the case of repayment in full of such Indebtedness.

 

SECTION 11.03.     No
Waiver. Neither a failure nor a delay on the part of either the Trustee or the Holders in exercising any right, power or privilege
under this Article 11 shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or further
exercise of any right, power or privilege. The rights, remedies and benefits of the Trustee and the Holders herein expressly specified
are cumulative and not exclusive of any other rights, remedies or benefits which either may have under this Article 11 at law, in
equity, by statute or otherwise.

 

SECTION 11.04.     Modification.
No modification, amendment or waiver of any provision of this Article 11, nor the consent to any departure by any Guarantor therefrom,
shall in any event be effective unless the same shall be in writing and signed by the Trustee, and then such waiver or consent shall be
effective only in the specific instance and for the purpose for which given. No notice to or demand on any Guarantor in any case shall
entitle such Guarantor to any other or further notice or demand in the same, similar or other circumstances.

 

SECTION 11.05.     Execution
of Supplemental Indenture for Future Guarantors. Each Subsidiary and other Person which is required or elects to become a Guarantor
pursuant to Section 4.10 shall promptly execute and deliver to the Trustee a supplemental indenture in the form of Exhibit C
hereto pursuant to which such Subsidiary or other Person shall become a Guarantor under this Article 11 and shall guarantee the Guaranteed
Obligations. Concurrently with the execution and delivery of such supplemental indenture, the Issuer shall deliver to the Trustee an Officer’s
Certificate stating that such supplemental indenture is authorized or permitted by this Indenture.

 

SECTION 11.06.     Non-Impairment.

electronic methods to submit instructions and directions to the Trustee or the Collateral Agent, as applicable, including without limitation
the risk of the Trustee or the Collateral Agent, as applicable, acting on unauthorized instructions, and the risk or interception and

Securities which a Trust Officer or the Trustee actually knows are so owned shall be so disregarded. Subject to the foregoing, only Securities

each party irrevocably submits to the non-exclusive jurisdiction of the Specified Courts in any Related Proceeding. Service of any process,
summons, notice or document by mail to such party’s address set forth above shall be effective service of process for any Related
Proceeding brought in any Specified Court. The parties irrevocably and unconditionally waive any objection to the laying of venue of any
Related Proceeding in the Specified Courts and irrevocably and unconditionally waive and agree not to plead or claim in any Specified
Court that any Related Proceeding brought in any Specified Court has been brought in an inconvenient forum. The Trustee and Collateral
Agent reserve the right to bring an action in any court that has jurisdiction over the trust estate, which may be a court other than the
Specified Courts, when seeking a direction from a court in the administration of the trust estate. On the Completion Date, each Guarantor
that becomes party to this Indenture via a supplemental indenture in the form of Exhibit C hereto that is organized outside the United
States will appoint (i) the Issuer or a Guarantor organized in the United States, any state thereof or the District of Columbia,

or the District of Columbia, Corporation Trust Company (or another company providing a similar service), in each case as its agent for
service of process or other legal summons for purposes of any Related Proceedings that may be instituted in any Specified Courts.

 

(b)            Waiver
of Immunity. With respect to any Related Proceeding, each party irrevocably waives, to the fullest extent permitted by applicable
law, all immunity (whether on the basis of sovereignty or otherwise) from jurisdiction, service of process, attachment (both before and
after judgment) and execution to which it might otherwise be entitled in the Specified Courts, and with respect to any suits, actions,
or proceedings instituted in regard to the enforcement of a judgment of any Specified Court in a Related Proceeding (a “Related
Judgment”), each party waives any such immunity in the Specified Courts or any other court of competent jurisdiction, and will
not raise or claim or cause to be pleaded any such immunity at or in respect of any such Related Proceeding or Related Judgment, including,
without limitation, any immunity pursuant to the United States Foreign Sovereign Immunities Act of 1976, as amended.

the account or benefit of a U.S. Person (other than an Initial Purchaser). A beneficial interest in an Unrestricted Global Security may

orders or instructions shall be required to be delivered to the Registrar to effect the transfers described in this Section 2.2(b)(i).

in an amount equal to the beneficial interest to be transferred or exchanged and (2) instructions given in accordance with the applicable
rules and procedures of the Depository containing information regarding the Agent Member account to be credited with such increase.

(A)            if
the transferee will take delivery in the form of a beneficial interest in a Rule 144A Global Security, then the transferor must deliver
a certificate in the form attached to the applicable Security; and

Unrestricted Global Security or transferred to a Person who takes delivery thereof in the form of a beneficial interest in an Unrestricted
Global Security if the exchange or transfer complies with the requirements of Section 2.2(b)(ii) above and the Registrar receives
the following:

rules and procedures of the Depository, Euroclear or Clearstream, as applicable, so require, an Opinion of Counsel to the
Issuer and the Registrar to the effect that such exchange or transfer is in compliance with the Securities Act and that the
restrictions on transfer contained herein and in the Restricted Securities Legend are no longer required in order to maintain
compliance with the Securities Act. If any such transfer or exchange is effected pursuant to this Section 2.2(b)(iv) at a
time when an Unrestricted Global Security has not yet been issued, the Issuer shall issue and, upon receipt of an Authentication
Order, the Trustee (or the Authenticating Agent) shall authenticate one or more Unrestricted Global Securities in an aggregate
principal amount equal to the aggregate principal amount of beneficial interests transferred or exchanged pursuant to this
Section 2.2(b)(iv).

Capitalized terms used herein have the meanings assigned
to them in the Indenture referred to below unless otherwise indicated.

 

1.            Interest

 

CLARIVATE
SCIENCE HOLDINGS CORPORATION, a Delaware corporation (the “Issuer”), promises to pay interest on the principal
amount of this Security at the rate per annum shown above. The Issuer shall pay interest semiannually on June 30 and December 30
of each year, commencing December 30, 2021.1
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 or duly provided for, from June 24, 2021 until the principal hereof is due. Interest shall be computed on the basis
of a 360-day year of twelve 30-day months. The Issuer shall pay interest on overdue principal at the rate borne by the Securities, 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 on the Securities (except
defaulted interest) to the Persons who are registered Holders at the close of business on the June 15 or December 15 next preceding
the interest payment date even if Securities are canceled after the record date and on or before the interest payment date (whether or
not a Business Day). The Holders must surrender Securities to a Paying Agent to collect principal payments. The Issuer shall pay principal,
premium, if any, and interest in U.S. Dollars. Payments in respect of the Securities represented by a Global Security (including principal
(upon presentation thereof to the Paying Agent), premium, if any, and interest) shall be made by wire transfer of immediately available
funds to the accounts specified by DTC or any successor depository. The Issuer will make all payments in respect of a certificated Security
(including principal, premium, if any, and interest), at the office of the 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; provided, however, that payments
on the Securities may also be made, in the case of a Holder of at least $1,000,000 aggregate principal amount of Securities, by wire transfer
to a U.S. Dollar account maintained by the payee with a bank in the United States if such Holder elects payment by wire transfer by giving
written notice to the Trustee or a Paying Agent to such effect designating such account no later than 30 days immediately preceding
the relevant due date for payment (or such other date as the Trustee may accept in its discretion).

 

3.            Paying
Agent and Registrar

 

Initially, Wilmington Trust, National Association
will act as the Paying Agent and Registrar. The Issuer may appoint and change any Paying Agent or Registrar without notice. The Issuer
or any domestically incorporated Wholly Owned Subsidiary of UK Holdco may act as Paying Agent or Registrar.

    A-6

     

    

 

4.            Indenture

 

The Issuer issued the Securities under an Indenture
dated as of June 24, 2021 (the “Indenture”), among the Issuer, the Guarantors from time to time party thereto,
the Trustee and Collateral Agent. Terms defined in the Indenture and not defined herein have the meanings ascribed thereto in the Indenture.
The Securities are subject to all terms and provisions of the Indenture, and the Holders are referred to the Indenture for a statement
of such terms and provisions. To the extent any provision of this Security conflicts with the express provisions of the Indenture, the
provisions of the Indenture shall govern and be controlling.

 

Prior to the Escrow Release Date, the Securities
will be senior secured obligations of the Issuer, secured by a first-priority security interest in the Escrow Account, as further described
in paragraph 21 hereof. Following the Completion Date, the Securities will be senior (and, following the grant of security interests,
secured) obligations of the Issuer. [This Security is one of the Original Securities referred to in the Indenture.] [This Security is
an Additional Security referred to in the Indenture.]

 

Prior to the Escrow Release Date, the Securities
will not be guaranteed. To guarantee the due and punctual payment of the principal, premium, if any, and interest, on the Securities and
all other amounts payable by the Issuer under the Indenture and the Securities when and as the same shall be due and payable, whether
at maturity, by acceleration or otherwise, according to the terms of the Securities and the Indenture, on the Completion Date, the Guarantors
will, jointly and severally, irrevocably and unconditionally guarantee the Guaranteed Obligations on a senior (and, upon the grant of
security interests on or after the Completion Date, secured) basis pursuant to the terms of the Indenture by executing a supplemental
indenture in the form of Exhibit C to the Indenture, and to the extent required by the Indenture.

 

5.            Optional
Redemption

 

Except
as set forth in the following two paragraphs, the Securities shall not be redeemable at the option of the Issuer prior to June 30,
2024. Thereafter, the Securities shall be redeemable at the option of the Issuer, in whole at any time or in part from time to time, upon
not less than 10 nor more than 60 days’ prior notice sent electronically or mailed by first-class mail to each Holder’s
registered address or provided otherwise in accordance with the procedures of DTC, at the following redemption prices (expressed as a
percentage of principal amount), plus accrued and unpaid interest, if any, to, but not including, the redemption date (subject
to the right of the Holders of record on the relevant record date to receive interest due on the relevant interest payment date), if redeemed
during the 12-month period commencing on June 30 of the years set forth below:

 

	Period	 	Redemption Price	 
	2024	 	 	101.938	%
	2025	 	 	100.969	%
	2026 and thereafter	 	 	100.000	%

 

In
addition, at any time prior to June 30, 2024, the Issuer may redeem the Securities at its option, in whole at any time or
in part from time to time, upon not less than 10 nor more than 60 days’ prior notice sent electronically or mailed by first-class
mail to each Holder’s registered address or provided otherwise in accordance with the procedures of DTC, at a redemption price equal
to 100% of the principal amount of the Securities redeemed plus the Applicable Premium, and accrued and unpaid interest, if any,
to, but not including, the applicable redemption date (subject to the right of the Holders of record on the relevant record date to receive
interest due on the relevant interest payment date).

 

    A-7

the foregoing, at any time and from time to time prior to June 30, 2024, the Issuer may redeem in the aggregate up to 40%
of the aggregate principal amount of the Securities issued (calculated after giving effect to any issuance of any Additional Securities)
with funds in an aggregate amount not exceeding the net cash proceeds of one or more Equity Offerings by UK Holdco or any direct or indirect
parent of UK Holdco, in each case, to the extent the net cash proceeds thereof are contributed to the common or preferred equity capital
(other than Disqualified Stock) of the Issuer or UK Holdco or used to purchase Capital Stock (other than Disqualified Stock) of the Issuer
or UK Holdco from it, at a redemption price (expressed as a percentage of the principal amount thereof) of 103.875% plus accrued
and unpaid interest, if any, to, but not including, the redemption date (subject to the right of the Holders of record on the relevant
record date to receive interest due on the relevant interest payment date); provided, however, that at least 50% of the
original aggregate principal amount of the Securities issued on the Issue Date remain outstanding after each such redemption, unless all
such Securities are redeemed substantially concurrently; and provided, further, that such redemption shall occur within
120 days after the date on which any such Equity Offering is consummated upon not less than 10 nor more than 60 days’ notice provided
to each Holder being redeemed and otherwise in accordance with the procedures set forth in the Indenture.

 

In connection with any tender offer for the Securities,
including a Change of Control Offer, a Collateral Asset Sale Offer or an Asset Sale Offer, if Holders of not less than 90% in aggregate
principal amount of the outstanding Securities validly tender and do not withdraw such Securities in such tender offer and the Issuer,
or any third party making such tender offer in lieu of the Issuer as described in the Indenture, purchases all of the Securities validly
tendered and not withdrawn by such Holders, the Issuer or such third party will have the right, upon not less than 10 days nor more than
60 days’ prior notice, provided that such notice is given not more than 30 days following such purchase pursuant to such
tender offer described in the Indenture), to redeem all Securities that remain outstanding following such purchase at a redemption price
in cash equal to the price offered to each other Holder in such tender offer plus, to the extent not included in such tender offer
payment, accrued and unpaid interest, if any, to, but excluding, the redemption date.

 

In connection with any redemption of Securities (including
with funds in an aggregate amount not exceeding the net cash proceeds of an Equity Offering), any such redemption may, at the Issuer’s
discretion, be subject to one or more conditions precedent, including the completion of any related Equity Offering. In addition, if such
redemption or notice is subject to satisfaction of one or more conditions precedent, such notice shall state that, in the Issuer’s
discretion, the redemption date may be delayed until such time (including more than 60 days after the date the notice of redemption was
sent) as any or all such conditions shall be satisfied (or waived by the Issuer in its sole discretion), 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 so delayed. In addition, the Issuer may provide in such notice that payment of the redemption price and performance
of the Issuer’s obligations with respect to such redemption may be performed by another Person.

 

6.            Mandatory
Redemption; Special Mandatory Redemption

 

Except in the case of a Special Mandatory Redemption
(as further described in Section 3.12(c) of the Indenture), the Issuer shall not be required to redeem or make any sinking fund
payment with respect to the Securities. In the event that (i) the Escrow Release Date does not take place on or prior to November 8,
2021, (ii) the Issuer shall have notified the Escrow Agent in writing that in its reasonable judgment, the ProQuest Acquisition will
not be consummated on or prior to such date or (iii) the ProQuest Agreement has been terminated, then the Issuer will redeem the
Securities on the terms set forth in Section 3.12(c) of the Indenture.

 

    A-8

     

    

 

7.            Notice
of Redemption

 

Other than in the case of a Special Mandatory Redemption,
which shall be subject to the terms of Section 3.12(c) of the Indenture, notice of redemption will be sent electronically or
mailed by first-class mail at least 10 days but not more than 60 days before the redemption date to each Holder of Securities
to be redeemed at his, her or its registered address or provided otherwise in accordance with the procedures of the Depository. Securities
in denominations larger than $2,000 may be redeemed in part but only in whole multiples of $1,000 to the extent practicable. If money
sufficient to pay the redemption price of and accrued and unpaid interest on all Securities (or portions thereof) to be redeemed on the
redemption date is deposited with a Paying Agent on or before the redemption date and certain other conditions are satisfied, on and after
such redemption date, interest ceases to accrue on such Securities (or such portions thereof) called for redemption.

 

8.            Repurchase
of Securities at the Option of the Holders upon Change of Control and Asset Sales

 

Upon the occurrence of a Change of Control, each
Holder shall have the right, subject to certain conditions specified in the Indenture, to require the Issuer to repurchase all or any
part of such Holder’s Securities at a purchase price in cash equal to the Change of Control Payment, plus accrued and unpaid
interest, if any, to, but not including, the date of repurchase (subject to the right of the Holders of record on the relevant record
date to receive interest due on the relevant interest payment date), as provided in, and subject to the terms of, the Indenture.

 

In accordance with Section 4.06 of the Indenture,
the Issuer may be required to use Excess Proceeds or Collateral Excess Proceeds to offer to purchase Securities upon the occurrence of
certain Asset Sales.

 

9.            Denominations;
Transfer; Exchange

 

The Securities are in registered form, without coupons,
in minimum denominations of $2,000 and any integral multiple of $1,000 in excess thereof. A Holder shall register the transfer of or exchange
of Securities in accordance with the Indenture. Upon any registration of transfer or exchange, the Registrar and the Trustee may require
a Holder, among other things, to furnish appropriate endorsements or transfer documents and to pay any taxes required by law or permitted
by the Indenture. The Registrar need not register the transfer of or exchange any Securities selected for redemption (except, in the case
of a Security to be redeemed in part, the portion of the Security not to be redeemed) or to transfer or exchange any Securities for a
period of 15 days prior to the sending of a notice of redemption or transfer or exchange any Securities to be redeemed or tendered
and not withdrawn in connection with a Change of Control Offer, a Collateral Asset Sale Offer or an Asset Sale Offer.

 

10.            Persons
Deemed Owners

 

The registered Holder of this Security shall be treated
as the owner of it for all purposes.

 

11.            Unclaimed
Money

 

If money for the payment of principal or interest
remains unclaimed for two years, the Trustee and a Paying Agent shall pay the money back to the Issuer at its written request unless an
abandoned property law designates another Person. After any such payment, the Holders entitled to the money must look to the Issuer for
payment as general creditors and the Trustee and a Paying Agent shall have no further liability with respect to such monies.

 

    A-9

     

    

 

12.            Discharge
and Defeasance

 

Subject to certain conditions, the Issuer at any
time may terminate some of or all its obligations under the Securities, the Indenture and the applicable Security Documents if the Issuer
deposits with the Trustee money or U.S. Government Obligations for the payment of principal of, and interest on the Securities to redemption,
or maturity, as the case may be.

 

13.            Amendment,
Waiver

 

Subject to certain exceptions set forth in the Indenture,
including the circumstances set forth in Section 9.02 of the Indenture, (i) the Indenture, the Securities, the Guarantees or
the Security Documents may be amended or supplemented with the consent of the Holders of at least a majority in aggregate principal amount
of the Securities then outstanding voting as a single class (including, without limitation, consents obtained in connection with a purchase
of, or tender offer or exchange offer for, such Securities) and (ii) any existing or past default or compliance with any provisions
of such documents may be waived with the consent of the Holders of a majority in principal amount of the Securities then outstanding (including,
without limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, such Securities). Subject
to certain exceptions set forth in the Indenture, without the consent of any Holder, the Issuer and the Trustee may amend the Indenture,
the Securities, the Guarantees or the Security Documents in the circumstances set forth in Section 9.01 of the Indenture.

 

In addition, without the consent of the Holders of
at least 662⁄3% in principal amount of the Securities then outstanding, no amendment, supplement or waiver may modify any Security
Document or the provisions in this Indenture dealing with the Collateral of the Security Documents that would have the impact of releasing
all or substantially all of the Collateral from the Liens of the Security Documents (except as permitted by the terms of this Indenture
and the Security Documents) or change or alter the priority of the security interests in the Collateral.

 

14.            Defaults
and Remedies

 

If an Event of Default (other than an Event of Default
relating to certain events of bankruptcy, insolvency or reorganization of the Issuer) occurs and is continuing, the Trustee by written
notice to the Issuer or the Holders of at least 30% of the aggregate principal amount of outstanding Securities by written notice to the
Issuer and the Trustee, may declare the principal of, premium, if any, and accrued but unpaid interest, on all the Securities to be due
and payable. Upon such a declaration, such principal and interest, will be due and payable immediately. If an Event of Default relating
to certain events of bankruptcy, insolvency or reorganization of the Issuer occurs, the principal of, premium, if any, and interest on
the Securities shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee
or any Holders. The Holders of a majority in principal amount of the outstanding Securities by notice to the Trustee may rescind an acceleration
and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default have been
cured or waived except nonpayment of principal or interest that has become due solely because of acceleration. No such rescission shall
affect any subsequent Default or impair any right consequent thereto.

 

 

    A-10

     

    

 

If
an Event of Default occurs and is continuing, the Trustee shall be under no obligation to exercise any of the rights or powers under the
Indenture at the request or direction of any of the Holders unless such Holders have offered to the Trustee indemnity and/or security
(which may include pre-funding) satisfactory to it against all losses, liabilities and expenses which might be Incurred by it in compliance
with such request or direction. Except to enforce the right to receive payment of principal, premium (if any) or interest when due, no
Holder may pursue any remedy with respect to the Indenture or the Securities unless (i) the Holder gives to the Trustee written notice
stating that an Event of Default is continuing, (ii) the Holders of at least 30% of the aggregate principal amount of the Securities
then outstanding make a written request to the Trustee to pursue the remedy, (iii) such Holder or Holders offer to the Trustee security
or indemnity (which may include pre-funding) satisfactory to it against any loss, liability or expense, (iv) the Trustee does not
comply with such request within 60 days after the receipt of the request and the offer of security or indemnity and (v) the
Holders of a majority in principal amount of outstanding Securities do not give the Trustee a direction inconsistent with the request
within such 60-day period. Subject to certain restrictions, the Holders of a majority in principal amount of the Securities then outstanding
may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust
or power conferred on the Trustee. The Trustee, however, may refuse to follow any direction that conflicts with law or the Indenture or,
subject to Section 7.01 of the Indenture, that the Trustee determines is unduly prejudicial to the rights of any other Holder (it
being understood that the Trustee does not have an affirmative duty to ascertain whether or not any action or forbearance is unduly prejudicial
to such Holders) or that would involve the Trustee in personal liability, provided, however, that the Trustee may take any
other action deemed proper by the Trustee that is not inconsistent with such direction. Prior to taking any action under the Indenture,
the Trustee shall be entitled to indemnification and/or security (which may include pre-funding) satisfactory to it against all losses,
liabilities and expenses caused by taking or not taking such action.

 

15.            Trustee
Dealings with the Issuer

 

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

 

16.            No
Recourse Against Others

 

No director, officer, employee, incorporator or holder
of any equity interests in the Issuer or of any Guarantor or any other direct or indirect parent, as such, shall have any liability for
any obligations of the Issuer or the Guarantors under the Securities, the Indenture or the Guarantees or for any claim based on, in respect
of, or by reason of, such obligations or their creation. Each Holder of Securities by accepting a Security waives and releases all such
liability. The waiver and release are part of the consideration for issuance of the Securities.

 

17.            Authentication

 

This Security shall not be valid until an authorized
signatory of the Trustee (or an authenticating agent) manually signs the certificate of authentication on the other side of this Security.

 

18.            Abbreviations

a Holder or an assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the entireties), JT TEN (=joint tenants with rights
of survivorship and not as tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors Act).

 

    A-11

     

    

 

19.            Governing
Law

 

THIS SECURITY SHALL BE GOVERNED BY, AND CONSTRUED
IN ACCORDANCE WITH, THE INTERNAL LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED IN SUCH STATE WITHOUT

Numbers and ISINs

 

The Issuer has caused CUSIP numbers and ISINs to
be printed on the Securities and has directed the Trustee to use CUSIP numbers and ISINs. No representation is made as to the accuracy
of such numbers either as printed on the Securities or as contained in any notice of redemption and reliance may be placed only on the
other identification numbers placed thereon.

 

21 .            Security

 

Prior to the Escrow Release Date, the Securities
will be secured by a security interest in the Escrow Account and all amounts on deposit therein on the terms and subject to the conditions
set forth in the Indenture and the Escrow Agreement. On and after the Completion Date, and upon the grant of security interests to secure
the Securities, the Securities will be secured by the Collateral on the terms and subject to the conditions set forth in the Indenture,
the First Lien Intercreditor Agreement and the Security Documents. The Collateral Agent will hold the security interest in the Collateral
for the benefit of the Holders of the Securities, in each case pursuant to the Security Documents, and, if applicable, the First Lien
Intercreditor Agreement and any other Acceptable Intercreditor Agreement. Each Holder, by accepting this Security, consents and agrees
to the terms of the Escrow Agreement and, as and when entered into, the Security Documents (including the provisions providing for the
foreclosure and release of Collateral), the First Lien Intercreditor Agreement and any other Acceptable Intercreditor Agreement as the
same may be in effect or may be amended from time to time in accordance with their terms and the Indenture and authorizes and directs
the Trustee and the Collateral Agent to enter into the Escrow Agreement, Security Documents, the First Lien Intercreditor Agreement and
any other Acceptable Intercreditor Agreement, and to perform their obligations and exercise their rights thereunder in accordance therewith.

 

The Issuer will furnish to any Holder of Securities
upon written request and without charge to the Holder a copy of the Indenture which has in it the text of this Security.

Ladies and Gentlemen:

 

This certificate is delivered to request a transfer
of $[       ] principal amount of the 3.875% Senior Secured Notes due 2028 (the “Securities”)
of CLARIVATE SCIENCE HOLDINGS CORPORATION (the “Issuer”).

 

Upon transfer, the Securities would be registered
in the name of the new beneficial owner as follows:

 

	Name:	 	 
	 	 	 
	Address:	 	 
	 	 	 
	Taxpayer ID Number:	 	 

 

The undersigned represents and warrants to you that:

 

1.            We
are an institutional “accredited investor” (as defined in Rule 501(a)(1), (2), (3) or (7) under the
Securities Act of 1933, as amended (the “Securities Act”)), purchasing for our own account or for the account of such
an institutional “accredited investor” at least $250,000 principal amount of the Securities, and we are acquiring the
Securities not with a view to, or for offer or sale in connection with, any distribution in violation of the Securities Act. We have such
knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of our investment in the
Securities, and we invest in or purchase securities similar to the Securities in the normal course of our business. We, and any accounts
for which we are acting, are each able to bear the economic risk of our or its investment.

 

    B-1

     

    

 

2.            We
understand that the Securities have not been registered under the Securities Act and, unless so registered, may not be sold except as
permitted in the following sentence. We agree on our own behalf and on behalf of any investor account for which we are purchasing Securities
to offer, sell or otherwise transfer such Securities prior to the date that is one year after the later of the date of original issue
and the last date on which the Issuer or any affiliate of the Issuer was the owner of such Securities (or any predecessor thereto) (the
 “Resale Restriction Termination Date”) only (a) to the Issuer, (b) pursuant to a registration statement that
has been declared effective under the Securities Act, (c) in a transaction complying with the requirements of Rule 144A under
the Securities Act (“Rule 144A”), to a person we reasonably believe is a qualified institutional buyer under Rule 144A
(a “QIB”) that is purchasing for its own account or for the account of a QIB and to whom notice is given that the transfer
is being made in reliance on Rule 144A, (d) pursuant to offers and sales that occur outside the United States within the meaning
of Regulation S under the Securities Act, (e) to an institutional “accredited investor” within the meaning of Rule 501(a)(1),
(2), (3) or (7) under the Securities Act that is purchasing for its own account or for the account of such an institutional
 “accredited investor,” in each case in a minimum principal amount of Securities of $250,000, or (f) pursuant to any other
available exemption from the registration requirements of the Securities Act, subject in each of the foregoing cases to any requirement
of law that the disposition of our property or the property of such investor account or accounts be at all times within our or their control
and in compliance with any applicable state securities laws. The foregoing restrictions on resale will not apply subsequent to the Resale
Restriction Termination Date. If any resale or other transfer of the Securities is proposed to be made pursuant to clause (e) above
prior to the Resale Restriction Termination Date, the transferor shall deliver a letter from the transferee substantially in the form
of this letter to the Issuer and the Trustee, which shall provide, among other things, that the transferee is an institutional “accredited
investor” within the meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act and that it is acquiring
such Securities for investment purposes and not for distribution in violation of the Securities Act. Each purchaser acknowledges that
the Issuer and the Trustee reserve the right prior to the offer, sale or other transfer prior to the Resale Restriction Termination Date
of the Securities pursuant to clause (d), (e) or (f) above to require the delivery of an opinion of counsel, certifications
or other information satisfactory to the Issuer and the Trustee.

SECTION 1.03.         Certain
Interpretative Provisions.

 

(a)          For
purposes of all Financial Definitions and calculations in this Indenture, (i) there shall be excluded for any period the effects
of purchase accounting (including the effects of such adjustments pushed down to UK Holdco and the Restricted Subsidiaries) in component
amounts required or permitted by GAAP and related authoritative pronouncements (including the effects of such adjustments pushed down
to UK Holdco and the Restricted Subsidiaries), as a result of the Transactions, any acquisition consummated prior to the Completion Date,
any acquisitions permitted under this Indenture, or the amortization or write-off of any amounts thereof and (ii) effect shall not
be given to (A) any election under Accounting Standards Codification 825-10-25 (previously referred to as Statement of Financial
Accounting Standards 159) (or any other Accounting Standards Codification, International Accounting Standard or Financial Accounting
Standard having a similar result or effect) to value any Indebtedness or other liabilities of UK Holdco or any Subsidiary at “fair
value,” as defined therein, (B) any treatment of Indebtedness in respect of convertible debt instruments under Accounting Standards
Codification 470-20 (or any other Accounting Standards Codification, International Accounting Standard or Financial Accounting Standard
having a similar result or effect) to value any such Indebtedness in a reduced or bifurcated manner as described therein, and such Indebtedness
shall at all times be valued at the full stated principal amount thereof or (C) the application of Accounting Standards Codification
480, 815, 805 and 718 (to the extent these pronouncements under Accounting Standards Codification 718 result in recording an equity award
as a liability on the consolidated balance sheet of UK Holdco and its Restricted Subsidiaries in the circumstance where, but for the application
of the pronouncements, such award would have been classified as equity). Any calculation or determination in this Indenture that requires
the application of GAAP across multiple quarters need not be calculated or determined using the same accounting standard for each constituent
quarter.

 

(b)          Notwithstanding
anything to the contrary contained in this Indenture or in the definition of “Capitalized Lease Obligation”, unless UK Holdco
elects otherwise, all obligations of any Person that are or would have been treated as operating leases for purposes of GAAP prior to
the issuance by the Financial Accounting Standards Board on February 25, 2016 of an Accounting Standards Update (the “ASU”)
shall continue to be accounted for as operating leases (and not be treated as financing or capital lease obligations or Indebtedness)
for purposes of all Financial Definitions, calculations and deliverables under this Indenture (including the calculation of Consolidated
Net Income and EBITDA) (whether or not such operating lease obligations were in effect on such date) notwithstanding the fact that such
obligations are required in accordance with the ASU or any other change in accounting treatment or otherwise (on a prospective or retroactive
basis or otherwise) to be treated as or to be re-characterized as financing or capital lease obligations or otherwise accounted for as
liabilities in financial statements. Interest on a Capitalized Lease Obligation shall be deemed to accrue at an interest rate reasonably
determined by a responsible financial or accounting officer of UK Holdco to be the rate of interest implicit in such Capitalized Lease
Obligation in accordance with GAAP.

 

    -45-

     

    

 

(c)          Interest
on Indebtedness that may optionally be determined at an interest rate based upon a factor of a prime or similar rate, a eurocurrency interbank
offered rate, or other rate, shall be deemed to have been based upon the rate actually chosen, or, if none, then based upon such optional
rate chosen as UK Holdco may designate.

 

(d)          For
purposes of covenant compliance, the amount of any Investment shall be the amount actually invested, without adjustment for subsequent
increases or decreases in the value of such Investment but giving effect to any returns or distributions of capital or repayment of principal
actually received in cash by such Person with respect thereto.

in the singular include the plural and words in the plural include the singular;

shown on a balance sheet of UK Holdco dated such date prepared in accordance with GAAP;

 

(h)          (i) the
principal amount of any Preferred Stock shall be (1) the maximum liquidation value of such Preferred Stock or (2) the maximum

Fixed Repurchase Price” of any Disqualified Stock or Preferred Stock that does not have a fixed repurchase price shall be calculated
in accordance with the terms of such Disqualified Stock or Preferred Stock as if such Disqualified Stock or Preferred Stock were purchased
on any date on which Consolidated Total Indebtedness shall be required to be determined pursuant to this Indenture, and if such price
is based upon, or measured by, the Fair Market Value of such Disqualified Stock or Preferred Stock, such Fair Market Value shall be determined
reasonably and in good faith by UK Holdco;

 

(j)           the
words “asset” and “property” shall be construed to have the same meaning and effect and to refer

term “consolidated” with respect to any Person refers to such Person consolidated with the Restricted Subsidiaries,
and excludes from such consolidation any Unrestricted Subsidiary as if such Unrestricted Subsidiary were not an Affiliate of such Person;

 

(o)          references
to agreements or other contractual obligations shall, unless otherwise specified, be deemed to refer to such agreements or contractual
obligations as amended, novated, supplemented, restated, extended, amended and restated or otherwise modified from time to time;

 

(p)          any
reference to any law in this Indenture shall include all statutory and regulatory provisions consolidating, amending, replacing, supplementing,
superseding or interpreting such law;

 

(q)          a
debt instrument includes any equity or hybrid instrument to the extent characterized as indebtedness;

 

(r)           the
words “ordinary course of business” or “ordinary course” shall, with respect to any Person, be deemed
to refer to items or actions that are consistent with industry practice or norms of such Person’s industry or such Person’s
past practice (it being understood that the sale of accounts receivable (and related assets) pursuant to supply-chain, factoring or reverse
factoring arrangements entered into by UK Holdco and its Restricted Subsidiaries shall be deemed to be in the ordinary course of business
so long as such accounts receivable (and related assets) are sold for cash in an amount not less than 95% of the face amount thereof);
and

 

(s)          unless
otherwise provided in this Indenture or the Securities, the words “execute,” “execution,” “signed,”
and “signature” and words of similar import used in or related to any document to be signed in connection with this Indenture
or the Securities or any of the transactions contemplated hereby (including amendments, waivers, consents and other modifications) will

SECTION 1.05.         Limited
Condition Transactions and Other Compliance Measurements.

 

(a)          Notwithstanding
anything to the contrary in this Indenture (including in connection with any calculation that is made on a Pro Forma Basis), in connection
with any action being taken in connection with a Limited Condition Transaction, for purposes of

 

(i)           determining
compliance with any provision of this Indenture which (i) requires the calculation of any financial ratio or test (including the
Consolidated First Lien Debt Ratio, Consolidated Secured Debt Ratio, Consolidated Total Debt Ratio and Fixed Charge Coverage Ratio) and/or
(ii) requires the absence of any Default or Event of Default (or any type of Default or Event of Default); or

 

(ii)          determining
compliance with any basket or other condition set forth in this Indenture (including baskets measured as a percentage of LTM EBITDA);

 

in each case, at the option of UK Holdco (UK Holdco’s
election to exercise such option in connection with any Limited Condition Transaction, an “LCT Election”), the date of determination
of whether any such action is permitted under this Indenture shall be deemed to be (A) in the case of any acquisition or other Investment
(including by way of merger, amalgamation or consolidation), any Asset Sale or any assumption or Incurrence of Indebtedness or issuance
of Preferred Stock or Disqualified Stock, or any transaction relating thereto, the date (or on the basis of the financial statements for
the most recently ended reference period) of entry into a binding letter of intent or the definitive agreements for such Limited Condition
Transaction (or, solely in connection with an acquisition (including by way of merger, amalgamation or consolidation) to which the United
Kingdom City Code on Takeovers and Mergers applies, the date on which a “Rule 2.7 Announcement” of a firm intention to
make an offer is made); (B) in the case of any repayment, repurchase or refinancing of Indebtedness, the date that the irrevocable
notice, which may be conditional, of such repayment, repurchase or refinancing of Indebtedness is given to the Holders of such Indebtedness;
or (C) in the case of any other Restricted Payment, at the time (or on the basis of the financial statements for the most recently
ended reference period) of the declaration of such Restricted Payment (the applicable date determined pursuant to clause (A), (B) or
(C), the “LCT Test Date”), and if, after giving effect to the Limited Condition Transaction and the other transactions to
be entered into in connection therewith (including any Incurrence of Indebtedness and the use of proceeds thereof) and, at the election
of UK Holdco, any other Limited Condition Transaction that has not been consummated but with respect to which UK Holdco has made an LCT
Election, on a Pro Forma Basis as if they had occurred at the beginning of the most recently completed reference period ending prior to
the LCT Test Date, UK Holdco or the applicable Restricted Subsidiary would have been permitted to take such action on the relevant LCT
Test Date in compliance with such ratio, test, basket or condition, such ratio, test, basket or condition shall be deemed to have been
complied with. For the avoidance of doubt, if UK Holdco has made an LCT Election and any of the ratios, tests, baskets or conditions for
which compliance was determined or tested as of the LCT Test Date are exceeded as a result of fluctuations in any such ratio, test, basket
or condition, including due to fluctuations in LTM EBITDA at or prior to the consummation of the relevant transaction or action, such
baskets, tests, ratios and conditions will not be deemed to have been exceeded as a result of such fluctuations.

 

(b)          In
addition, for purposes of determining the permissibility of any action, change, transaction or event that requires a calculation of any
financial ratio or financial test and/or the amount of EBITDA or Consolidated Net Income, such financial ratio, financial test or amount
shall, subject to Section 1.05(a), be calculated at the time such action is taken, such change is made, such transaction is consummated
or such event occurs, as the case may be, and no Default or Event of Default shall be deemed to have occurred solely as a result of a
change in such financial ratio, financial test or amount occurring after the time such action is taken, such change is made, such transaction
is consummated or such event occurs, as the case may be.

 

    -48-

     

    

 

(c)          Notwithstanding
anything to the contrary in this Indenture, unless UK Holdco otherwise notifies the Trustee, with respect to any amount Incurred or transaction
entered into (or consummated) in reliance on a provision of this Indenture that does not require compliance with a financial ratio or
financial test (any such amount, including any amount drawn under any revolving credit facility and any cap expressed as a percentage
of Consolidated Net Income or EBITDA, a “Fixed Amount”) substantially concurrently with any amount Incurred or transaction
entered into (or consummated) in reliance on a provision of this Indenture that requires compliance with a financial ratio or financial
test (any such amount, an “Incurrence-Based Amount”), it is understood and agreed that (i) the Incurrence of the
Incurrence-Based Amount shall be calculated first without giving effect to any Fixed Amount but giving full pro forma effect to the use
of proceeds of such Fixed Amount and the related transactions and (ii) the Incurrence of the Fixed Amount shall be calculated thereafter.
Unless UK Holdco elects otherwise, UK Holdco shall be deemed to have used amounts under an Incurrence-Based Amount then available to UK
Holdco prior to utilization of any amount under a Fixed Amount then available to UK Holdco.

 

 

(d)          Subject
to Sections 1.05(a), (b) and (c), all financial ratios and tests and the amount of Consolidated Net Income and EBITDA contained in
this Indenture that are calculated with respect to any reference period shall be calculated with respect to such reference period on a
Pro Forma Basis.

 

(e)          For
purposes of determining compliance with the covenants set forth under‎ Section 4.03 or Section 4.11 or the definition
of “Permitted Liens”, if any Indebtedness, Preferred Stock, Disqualified Stock or Lien is created or Incurred in reliance
on a basket measured by reference to a percentage of EBITDA, and any refinancing or replacement thereof would cause the percentage of
EBITDA to be exceeded if calculated based on the EBITDA on the date of such refinancing or replacement, such percentage of EBITDA will
be deemed not to be exceeded so long as the principal amount of such refinancing or replacement Indebtedness, Preferred Stock, Disqualified
Stock or other obligation does not exceed an amount sufficient to repay the principal amount of such Indebtedness, Preferred Stock, Disqualified
Stock or other obligation being refinanced or replaced, except by an amount equal to (x) the amount necessary to pay accrued and
unpaid interest, fees, underwriting discounts and expenses, including any premium and defeasance costs Incurred in connection with such
refinancing or replacement and (y) additional amounts permitted to be Incurred pursuant to Section 4.03.

THE SECURITIES

 

SECTION 2.01.        Amount
of Securities; Issuable in Series. The aggregate principal amount of Original Securities which may be authenticated and delivered
under this Indenture on the Issue Date is $1,000,000,000. The Securities may be issued in one or more series. All Securities of any one
series shall be substantially identical except as to denomination.

 

The Issuer may from time to time after the Issue
Date issue Additional Securities under this Indenture in an unlimited principal amount, so long as (i) the Incurrence of the Indebtedness
represented by such Additional Securities is at such time permitted by Section 4.03 and Section 4.11 and (ii) such Additional
Securities are issued in compliance with the other applicable provisions of this Indenture. With respect to any Additional Securities
issued after the Issue Date (except for Securities authenticated and delivered upon registration of transfer of, or in exchange for, or
in lieu of, other Securities pursuant to Sections 2.07, 2.08, 2.09, 2.10, 3.08, 3.09(e), 4.08(c) or the Appendix), there
shall be (a) established in or pursuant to a resolution of the Board of Directors of the Issuer and (b)(i) set forth or determined
in the manner provided in an Officer’s Certificate or (ii) established in one or more supplemental indentures hereto, prior
to the issuance of such Additional Securities:

 

    -49-

     

    

 

(1)            whether
such Additional Securities shall be issued as part of a new or existing series of Securities and the title of such Additional Securities
(which shall distinguish the Additional Securities of the series from Securities of any other series);

 

(2)            the
aggregate principal amount of such Additional Securities which may be authenticated and delivered under this Indenture;

 

(3)            the
issue price and issuance date of such Additional Securities, including the date from which interest on such Additional Securities shall
accrue; and

 

(4)            if
applicable, that such Additional Securities shall be issuable in whole or in part in the form of one or more Global Securities and, in
such case, the respective depositaries for such Global Securities, the form of any legend or legends which shall be borne by such Global
Securities in addition to or in lieu of those set forth in Exhibit A hereto and any circumstances in addition to or in lieu
of those set forth in Section 2.2 of the Appendix in which any such Global Security may be exchanged in whole or in part for
Additional Securities registered, or any transfer of such Global Security in whole or in part may be registered, in the name or names
of Persons other than the depositary for such Global Security or a nominee thereof.

 

If any of the terms of any Additional Securities
are established by action taken pursuant to a resolution of the Board of Directors of the Issuer, a copy of an appropriate record of such
action shall be certified by the Secretary or any Assistant Secretary of the Issuer and delivered to the Trustee at or prior to the delivery
of the Officer’s Certificate or the supplemental indenture hereto setting forth the terms of the Additional Securities.

 

Additionally, the Trustee shall receive an Officer’s
Certificate in accordance with Section 12.04, and the Trustee shall receive an Opinion of Counsel which shall state:

 

(1)          that
the form of such Additional Securities has been established by a supplemental indenture or by or pursuant to a resolution of the Board
of Directors in conformity with the provisions of this Indenture;

 

(2)          that
the terms of such Additional Securities have been established in conformity with the other provisions of this Indenture;

 

(3)          that
such Additional Securities, when authenticated and delivered by the Trustee or its Authenticating Agent and issued by the Issuer in the
manner and subject to any conditions specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the
Issuer, enforceable in accordance with their terms, subject to bankruptcy, insolvency, reorganization and other laws of general applicability
relating to or affecting the enforcement of creditors' rights and to general equity principles; and

 

(4)          that
all covenants and conditions precedent under this Indenture with respect to the issuance, authentication and delivery of such Additional
Securities have been complied with.

 

    -50-

     

    

 

SECTION 2.02.         Form and
Dating. Provisions relating to the Securities are set forth in the Appendix, which is hereby incorporated in and expressly
made a part of this Indenture. The Original Securities and the Trustee’s certificate of authentication, and any Additional Securities
(if issued as Transfer Restricted Definitive Securities) and the Trustee’s certificate of authentication, shall each be substantially
in the form of Exhibit A hereto, which is hereby incorporated in and expressly made a part of this Indenture. The Securities
may have notations, legends or endorsements required by law, stock exchange rule, agreements to which the Issuer or any Guarantor is
subject, if any, or usage (provided that any such notation, legend or endorsement is in a form acceptable to the Issuer). Each
Security shall be dated the date of its authentication. The Securities shall be issuable only in fully registered form without coupons
and only in minimum denominations of $2,000 and any integral multiples of $1,000 in excess thereof.

 

SECTION 2.03.         Execution
and Authentication. The Trustee or its Authenticating Agent shall authenticate and make available for delivery upon a written order
of the Issuer signed by one or more officers, directors or authorized signatories of the Issuer (an “Authentication Order”)
(a) Original Securities for original issue on the date hereof of $1,000,000,000 in aggregate principal amount of 4.875% Senior Notes
due 2029 and (b) subject to the terms of this Indenture, Additional Securities in an aggregate principal amount to be determined
at the time of issuance and specified therein. Such Authentication Order shall specify the amount of the Securities to be authenticated
and the date on which the original issue of Securities is to be authenticated. Notwithstanding anything to the contrary in this Indenture
or the Appendix, any issuance of Additional Securities after the Issue Date shall be in a minimum principal amount of $2,000 and
any integral multiples of $1,000 in excess thereof whether such Additional Securities are of the same or a different series than the
Original Securities. Prior to the authentication of the Original Securities, the Trustee shall receive an Officer’s Certificate
in accordance with Section 12.04.

 

One or more officers, directors or authorized signatories
of the Issuer shall sign the Securities for the Issuer by manual, facsimile or other electronic signature.

 

If an officer, director or authorized signatory whose
signature is on a Security no longer holds that office at the time the Trustee or its Authenticating Agent authenticates the Security,
the Security shall be valid nevertheless.

 

A Security shall not be valid until an authorized
signatory of the Trustee or its Authenticating Agent manually signs the certificate of authentication on the Security. The signature shall
be conclusive evidence that the Security has been authenticated under this Indenture.

 

The Trustee may appoint one or more authenticating
agents (each an “Authenticating Agent”) reasonably acceptable to the Issuer to authenticate the Securities. Any such
appointment shall be evidenced by an instrument signed by a Trust Officer, a copy of which shall be furnished to the Issuer. Unless limited
by the terms of such appointment, an authenticating agent may authenticate Securities whenever the Trustee may do so. Each reference in
this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as
any Registrar, Paying Agent or agent for service of notices and demands.

 

SECTION 2.04.         Registrar
and Paying Agent.

 

(a)          The
Issuer shall maintain (i) an office or agency where Securities may be presented for registration of transfer or for exchange (the
 “Registrar”) and (ii) an office or agency in the United States where Securities may be presented for payment (the
 “Paying Agent”). The Registrar shall keep a register of the Securities and of their transfer and exchange. The Issuer
may have one or more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrars.
The term “Paying Agent” includes the Paying Agent and any additional paying agents. The Issuer initially appoints the Trustee
as (i) Registrar and Paying Agent in connection with the Securities and (ii) the Securities Custodian with respect to the Global
Securities.

 

    -51-

     

    

 

Upon written request from the Issuer or each time
the register of Holders is amended, the Registrar shall provide the Issuer with a copy of the register of Holders.

 

(b)          The
Issuer shall enter into an appropriate agency agreement with any Registrar or Paying Agent not a party to this Indenture. The agreement
shall implement the provisions of this Indenture that relate to such agent. The Issuer shall notify the Trustee in writing of the name
and address of any such agent. If the Issuer fails to maintain a Registrar or Paying Agent, the Trustee shall act as such and shall be
entitled to appropriate compensation therefor pursuant to Section 7.06. The Issuer or any of its domestically organized Wholly Owned
Subsidiaries may act as Paying Agent or Registrar.

 

(c)          The
Issuer may remove any Registrar or Paying Agent upon written notice to such Registrar or Paying Agent and to the Trustee; provided,
however, that no such removal shall become effective until (i) if applicable, acceptance of an appointment by a successor
as evidenced by an appropriate agreement entered into by the Issuer and such successor Registrar or Paying Agent, as the case may be,
and delivered to the Trustee or (ii) written notification to the Trustee that the Trustee shall serve, to the extent it determines
that it is able, as Registrar or Paying Agent until the appointment of a successor in accordance with clause (i) above.

 

SECTION 2.05.          Paying
Agent to Hold Money in Trust. On or prior to 10:00 a.m. (New York City time) on each due date of the principal of and interest
on any Security, the Issuer shall deposit with the Paying Agent (or if the Issuer or a domestically organized Wholly Owned Subsidiary
is acting as Paying Agent, segregate and hold for the benefit of the Persons entitled thereto) a sum sufficient to pay such principal
and interest when so becoming due. The Issuer shall require each Paying Agent (other than the Trustee) to agree in writing that a Paying
Agent shall hold in trust for the benefit of Holders and the Trustee all money held by a Paying Agent for the payment of principal of
and interest on the Securities, and shall notify the Trustee in writing of any default by the Issuer in making any such payment. If the
Issuer or a domestically organized Wholly Owned Subsidiary of the Issuer acts as Paying Agent, it shall segregate the money held by it
as Paying Agent and hold it for the benefit of the Persons entitled thereto. The Issuer at any time may require a Paying Agent to pay
all money held by it to the Trustee and to account for any funds disbursed by such Paying Agent. During the continuance of a Default
under this Indenture, the Trustee may require a Paying Agent to pay all money held by it to the Trustee. Upon any bankruptcy or reorganization
proceedings relating to the Issuer, the Trustee will serve as Paying Agent. Upon complying with this Section 2.05, a Paying Agent
shall have no further liability for the money delivered to the Trustee. For the avoidance of doubt, a Paying Agent and the Trustee shall
be held harmless and have no liability with respect to payments and disbursements to be made by a Paying Agent and the Trustee until
they have confirmed receipt of funds sufficient to make the relevant payment. No money held by an Agent needs to be segregated except
as is required by law.

 

SECTION 2.06.         Holder
Lists. The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names
and addresses of Holders. If the Trustee is not the Registrar, the Issuer shall furnish, or cause the Registrar to furnish, to the Trustee,
in writing at least five Business Days before each interest payment date and at such other times as the Trustee may request in writing,
a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of Holders.

 

    -52-

     

    

 

SECTION 2.07.         Transfer
and Exchange. The Securities shall be issued in registered form and shall be transferable only upon the surrender of a Security for
registration of transfer and in compliance with the Appendix. When a Security is presented to the Registrar with a request to
register a transfer, the Registrar shall register the transfer as requested if its requirements therefor are met. When Securities are
presented to the Registrar with a request to exchange them for an equal principal amount of Securities of other denominations, the Registrar
shall make the exchange as requested if the same requirements are met. To permit registration of transfers and exchanges, the Issuer
shall execute and upon receipt of an Authentication Order the Trustee or its Authenticating Agent shall authenticate Securities at the
Registrar’s request. The Issuer may require a Holder to pay a sum sufficient to pay all Taxes, assessments or other governmental
charges in connection with any transfer or exchange pursuant to this Section 2.07. The Issuer shall not be required to make, and
the Registrar need not register, transfers or exchanges of Securities selected for redemption (except, in the case of Securities to be
redeemed in part, the portion thereof not to be redeemed) or of any Securities for a period of 15 days prior to the sending of a notice
of redemption or of any Securities to be redeemed or tendered and not withdrawn in connection with a Change of Control or an Asset Sale
Offer.

 

Prior to the due presentation for registration of
transfer of any Security, the Issuer, the Guarantors, the Trustee, the Paying Agent and the Registrar may deem and treat the Person in
whose name a Security is registered as the absolute owner of such Security for the purpose of receiving payment of principal of and interest,
if any, on such Security and for all other purposes whatsoever, whether or not such Security is overdue, and none of the Issuer, any Guarantor,
the Trustee, a Paying Agent or the Registrar shall be affected by notice to the contrary.

 

Any Holder of a beneficial interest in a Global Security
shall, by acceptance of such beneficial interest, agree that transfers of beneficial interests in such Global Security may be effected
only through a book-entry system maintained by (a) the Holder of such Global Security (or its agent) or (b) any Holder of a
beneficial interest in such Global Security, and that ownership of a beneficial interest in such Global Security shall be required to
be reflected in a book entry.

 

All Securities issued upon any transfer or exchange
pursuant to the terms of this Indenture shall evidence the same debt and shall be entitled to the same benefits under this Indenture as
the Securities surrendered upon such transfer or exchange.

 

The Trustee shall have no obligation or duty to monitor,
determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture, the Appendix or under applicable
law with respect to any transfer of any interest in any Security other than to require delivery of such certificates and other documentation
or evidence as are expressly required by, and to do so if and when expressly required by the terms of, this Indenture and the Appendix.

 

Neither the Trustee nor any of its agents shall have
any responsibility or liability for any actions taken or not taken by the depositary with which the Global Security is registered.

 

SECTION 2.08.         Replacement
Securities. If a mutilated Security is surrendered to the Registrar or if the Holder of a Security claims that the Security has been
lost, destroyed or wrongfully taken, the Issuer shall issue and the Trustee shall authenticate (upon receipt of an Authentication Order)
a replacement Security if the requirements of Section 8-405 of the Uniform Commercial Code are met, such that the Holder (a) satisfies
the Issuer or the Trustee within a reasonable time after such Holder has notice of such loss, destruction or wrongful taking and the
Registrar does not register a transfer prior to receiving such notification, (b) makes such request to the Issuer or the Trustee
prior to the Security being acquired by a protected purchaser as defined in Section 8-303 of the Uniform Commercial Code (a “protected
purchaser”) and (c) satisfies any other reasonable requirements of the Trustee. Such Holder shall furnish an indemnity
bond sufficient in the judgment of (i) the Trustee to protect the Trustee or (ii) the Issuer, to protect the Issuer, the Trustee,
a Paying Agent and the Registrar, from any loss that any of them may suffer if a Security is replaced. The Issuer and the Trustee may
charge the Holder for the Issuer’s or Trustee’s expenses in replacing a Security (including, without limitation, attorneys’
fees and disbursements in replacing such Security). In the event any such mutilated, lost, destroyed or wrongfully taken Security has
become or is about to become due and payable, the Issuer in its discretion may pay such Security instead of issuing a new Security in
replacement thereof.

 

    -53-

     

    

 

Every replacement Security is an additional obligation
of the Issuer.

 

The provisions of this Section 2.08 are exclusive
and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, lost,
destroyed or wrongfully taken Securities.

 

SECTION 2.09.         Outstanding
Securities. Securities outstanding at any time are all Securities authenticated by the Trustee or its Authenticating Agent except
for those canceled by it, those delivered to it for cancellation, those paid or replaced pursuant to Section 2.08 and those described
in this Section 2.09 as not outstanding. Subject to Section 12.06, a Security does not cease to be outstanding because the
Issuer or an Affiliate of the Issuer holds the Security.

 

If a Security is replaced pursuant to Section 2.08
(other than a mutilated Security surrendered for replacement), it ceases to be outstanding unless the Trustee and the Issuer receive proof
satisfactory to them that the replaced Security is held by a protected purchaser. A mutilated Security ceases to be outstanding upon surrender
of such Security and replacement thereof pursuant to Section 2.08.

 

If a Paying Agent holds, in accordance with this
Indenture, on a redemption date or maturity date money sufficient to pay all principal and interest payable on that date with respect
to the Securities (or portions thereof) to be redeemed or maturing, as the case may be, and no Paying Agent is prohibited from paying
such money to the Holders on that date pursuant to the terms of this Indenture, then on and after that date such Securities (or portions
thereof) cease to be outstanding and interest on them ceases to accrue.

 

SECTION 2.10.         Temporary
Securities. In the event that Definitive Securities are to be issued under the terms of this Indenture, until such Definitive Securities
are ready for delivery, the Issuer may prepare and the Trustee upon receipt of an Authentication Order shall authenticate temporary Securities.
Temporary Securities shall be substantially in the form of Definitive Securities but may have variations that the Issuer considers appropriate
for temporary Securities. Without unreasonable delay, the Issuer shall prepare and upon receipt of an Authentication Order the Trustee
shall authenticate Definitive Securities and make them available for delivery in exchange for temporary Securities upon surrender of
such temporary Securities at the office or agency of the Issuer, without charge to the Holder. Until such exchange, temporary Securities
shall be entitled to the same rights, benefits and privileges as Definitive Securities.

 

SECTION 2.11.         Cancellation.
The Issuer at any time may deliver Securities to the Registrar for cancellation. The Trustee and the Paying Agent shall forward to the
Registrar any Securities surrendered to them for registration of transfer, exchange or payment. The Registrar and no one else shall cancel
all Securities surrendered for registration of transfer, exchange, payment or cancellation and shall dispose of canceled Securities in
accordance with its customary procedures. The Issuer may not issue new Securities to replace Securities it has redeemed, paid or delivered
to the Registrar for cancellation. The Trustee shall not authenticate Securities in place of canceled Securities other than pursuant
to the terms of this Indenture.

 

    -54-

     

    

 

SECTION 2.12.         Defaulted
Interest. If the Issuer defaults in a payment of interest on the Securities, the Issuer shall pay the defaulted interest then borne
by the Securities (plus interest on such defaulted interest to the extent lawful), in any lawful manner. The Issuer may pay the
defaulted interest to the Persons who are Holders on a subsequent special record date. The Issuer shall fix or cause to be fixed any
such special record date and payment date and shall promptly mail or cause to be mailed to each affected Holder a notice that states
the special record date, the payment date and the amount of defaulted interest to be paid.

 

SECTION 2.13.         CUSIP
Numbers and ISINs. The Issuer in issuing the Securities may use CUSIP numbers and ISINs (if then generally in use) and, if so, the
Trustee shall use CUSIP numbers and ISINs in notices of redemption as a convenience to Holders; provided, however, that
any such notice may state that no representation is made as to the correctness of such numbers, either as printed on the Securities or
as contained in any notice of a redemption, that reliance may be placed only on the other identification numbers printed on the Securities
and that any such redemption shall not be affected by any defect in or omission of such numbers; provided, further, that
if any Additional Securities are not fungible with the Original Securities for U.S. federal income tax purposes, such Additional Securities
will have a separate CUSIP number and ISINs. The Issuer shall promptly advise the Trustee in writing of any change in the CUSIP numbers
and ISINs.

 

SECTION 2.14.         Calculation
of Specified Percentage of Securities. With respect to any matter requiring consent, waiver, approval or other action of the Holders
of a specified percentage of the principal amount of all the Securities, such percentage shall be calculated, on the relevant date of
determination, by dividing (a) the principal amount, as of such date of determination, of Securities, the Holders of which have
so consented by (b) the aggregate principal amount, as of such date of determination, of the Securities then outstanding, in each
case, as determined in accordance with Section 2.09 and Section 12.06 of this Indenture. Any such calculation made pursuant
to this Section 2.14 shall be made by the Issuer and delivered to the Trustee pursuant to an Officer’s Certificate.

 

SECTION 2.15.         Deposit
of Moneys. Subject to actual receipt of such funds as provided by Section 2.05 by the designated Paying Agent and in the case
of the Trustee, subject to the lien provided for in Section 7.06, such Paying Agent shall remit such payment in a timely manner
to the Holders on such day or date, as the case may be, to the Persons and in the manner set forth in Paragraph 2 of the Securities;
provided, however, that no Paying Agent shall be obliged to make a payment until it has received funds sufficient to make such payment.
The Issuer shall promptly notify the Trustee and the respective Paying Agent of its failure to so act.

 

ARTICLE 3

 

REDEMPTION

 

SECTION 3.01.         Optional
Redemption.

 

(a)          The
Securities may be redeemed, in whole, or from time to time in part, subject to the conditions and at the redemption prices set forth in
Paragraph 5 of the Form of Security set forth in Exhibit A hereto, which is hereby incorporated by reference and made
a part of this Indenture, together with accrued and unpaid interest to, but not including, the redemption date.

 

(b)          Notwithstanding
anything in this Indenture or the Securities to the contrary, in connection with any tender offer for the Securities, including a Change
of Control Offer or an Asset Sale Offer, if Holders of not less than 90% in aggregate principal amount of the outstanding Securities validly
tender and do not withdraw such Securities in such tender offer and the Issuer, or any third party making such tender offer in lieu of
the Issuer as described herein, purchases all of the Securities validly tendered and not withdrawn by such Holders, the Issuer or such
third party will have the right, upon not less than 10 days nor more than 60 days’ prior notice (provided that such notice is given
not more than 30 days following such purchase pursuant to such tender offer described herein), to redeem all Securities that remain outstanding
following such purchase at a redemption price in cash equal to the price offered to each other Holder in such tender offer plus, to the
extent not included in such tender offer payment, accrued and unpaid interest, if any, to, but excluding, the date of such redemption.

 

    -55-

     

    

 

SECTION 3.02.         Applicability
of Article. Redemption of Securities at the election of the Issuer or otherwise, as permitted or required by any provision of this
Indenture (including the optional redemption provisions of Paragraph 5 of the Form of Security set forth in Exhibit A
hereto), shall be made in accordance with such provision and this Article 3.

 

SECTION 3.03.         Notices
to Trustee. If the Issuer elects to redeem Securities pursuant to the optional redemption provisions of Paragraph 5 of the Form of
Security set forth in Exhibit A hereto, it shall notify the Trustee and the Paying Agent in writing of (i) the particular
part of Paragraph 5 of the Form of Security set forth in Exhibit A hereto pursuant to which the redemption shall occur,
(ii) the redemption date, (iii) the principal amount of Securities to be redeemed and (iv) the redemption price. The Issuer
shall give notice to the Trustee and the Paying Agent provided for in this Section 3.03 at least 10 days but not more than
60 days before a redemption date if the redemption is pursuant to Paragraph 5 of the Form of Security set forth in Exhibit A
hereto. Any such notice may be canceled at any time prior to notice of such redemption being sent to any Holder and shall thereby
be void and of no effect.

 

SECTION 3.04.         Selection
of Securities to Be Redeemed. In the case of any partial redemption, selection of the Securities for redemption will be made by the
Trustee in accordance with the procedures of the Depository; provided, that no such selection shall result in a Holder of Securities
with a principal amount of Securities less than the minimum denomination for the Securities. The Securities to be redeemed shall be selected
from outstanding Securities not previously called for redemption. Securities and portions of them selected shall be in minimum amounts
of $2,000 or a whole multiple of $1,000 in excess thereof. Provisions of this Indenture that apply to Securities called for redemption
also apply to portions of Securities called for redemption.

 

SECTION 3.05.         Notice
of Optional Redemption.

 

(a)          At
least 10 days but not more than 60 days before a redemption date pursuant to Paragraph 5 of the Form of Security set forth in
Exhibit A hereto, the Issuer shall send or cause to be sent, electronically or by first-class mail, a notice of redemption
to each Holder (with a copy to the Trustee and Paying Agent) whose Securities are to be redeemed to such Holder’s registered address
or otherwise in accordance with the procedures of the Depository; provided that redemption notices may be provided more than 60
days prior to a redemption date if the notice is issued in connection with a satisfaction or discharge of this Indenture or defeasance
of the Securities pursuant to this Indenture.

 

Any such notice shall identify the Securities to
be redeemed and shall state:

 

(i)             the
redemption date;

 

(ii)            the
redemption price and the amount of accrued interest to the redemption date;

 

(iii)           the
name and address of the Paying Agent;

 

(iv)           that
Securities called for redemption must be surrendered to the Paying Agent to collect the redemption price, plus accrued interest;

 

(v)            if
fewer than all the outstanding Securities are to be redeemed, the certificate numbers (if applicable) and principal amounts of the particular
Securities to be redeemed, the aggregate principal amount of the Securities to be redeemed and the aggregate principal amount of the Securities
to be outstanding after such partial redemption;

 

(vi)           that,
unless the Issuer defaults in making such redemption payment or any Paying Agent is prohibited from making such payment pursuant to the
terms of this Indenture, interest on Securities (or portion thereof) called for redemption ceases to accrue on and after the redemption
date;

 

    -56-

     

    

 

(vii)             the
CUSIP number and ISIN, if any, printed on the Securities being redeemed; and

 

(viii)            that
no representation is made as to the correctness or accuracy of the CUSIP number or ISIN if any, listed in such notice or printed on the
Securities.

 

In connection with any redemption of Securities (including
with funds in an aggregate amount not exceeding the net cash proceeds of an Equity Offering), any such redemption may, at the Issuer’s
discretion, be subject to one or more conditions precedent, including the completion of any related Equity Offering. In addition, if such
redemption or notice is subject to satisfaction of one or more conditions precedent, such notice shall state that, in the Issuer’s
discretion, the redemption date may be delayed until such time (including more than 60 days after the date the notice of redemption was
sent) as any or all such conditions shall be satisfied (or waived by the Issuer in its sole discretion), 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. In addition, the Issuer may provide in such notice that payment of the redemption price and
performance of the Issuer’s obligations with respect to such redemption may be performed by another Person.

 

(b)            At
the Issuer’s request, the Trustee shall give the notice of redemption in the Issuer’s name and at the Issuer’s expense;
provided, however, that the Issuer has delivered to the Trustee, at least 5 Business Days (unless a shorter period is acceptable
to the Trustee) prior to the date the redemption notice is sent to Holders, an Officer’s Certificate requesting that the Trustee
give such notice. In such event, the Issuer shall provide the Trustee in writing with the information required by this Section 3.05.

 

SECTION 3.06.     Effect
of Notice of Redemption. Once notice of redemption is provided in accordance with Section 3.05, Securities called for redemption
become due and payable on the redemption date and at the redemption price stated in the notice (except to the extent such redemption
is conditional as set forth in Section 3.05). Upon surrender to any Paying Agent, such Securities shall be paid at the redemption
price stated in the notice, plus accrued interest to the redemption date; provided, however, that if the redemption
date is after a regular record date and on or prior to the interest payment date, the accrued interest shall be payable to the Holder
of the redeemed Securities registered on the relevant record date. Failure to give notice or any defect in the notice to any Holder shall
not affect the validity of the notice to any other Holder.

 

SECTION 3.07.     Deposit
of Redemption Price. Prior to 10:00 a.m., New York City time, on the redemption date, the Issuer shall deposit with the Paying
Agent (or, if UK Holdco or a Wholly Owned Subsidiary of UK Holdco is a Paying Agent, shall segregate and hold in trust) money sufficient
to pay the redemption price of and accrued interest on all Securities or portions thereof to be redeemed on that date other than Securities
or portions of Securities called for redemption that have been delivered by the Issuer to the Trustee for cancellation. On and after
the redemption date, interest shall cease to accrue on Securities or portions thereof called for redemption so long as the Issuer has
deposited with the Paying Agent funds sufficient to pay the principal of, plus accrued and unpaid interest on, the Securities
to be redeemed, unless the Paying Agent is prohibited from making such payment pursuant to the terms of this Indenture. For the avoidance
of doubt, the Paying Agent and the Trustee shall be held harmless and have no liability with respect to payments and disbursements to
be made by the Paying Agent and the Trustee until they have confirmed receipt of funds sufficient to make the relevant payment.

SECTION 3.08.     Securities
Redeemed in Part. In the case of Definitive Securities, upon surrender of a Security that is redeemed in part, the Issuer shall execute
and upon receipt of an Authentication Order the Trustee or the Authenticating Agent shall authenticate for the Holder (at the Issuer’s
expense) a new Security equal in principal amount to the unredeemed portion of the Security surrendered.

 

SECTION 3.09.     Offer
to Purchase by Application of Excess Proceeds.

 

(a)            In
the event that, pursuant to Section 4.06 hereof, UK Holdco is required to commence an Asset Sale Offer, it will follow the procedures
specified below.

 

(b)            The
Asset Sale Offer, shall be made to all Holders with respect to offers to purchase, prepay or redeem with the proceeds of sales of assets.
The Asset Sale Offer will remain open for a period of at least 20 Business Days following its commencement and not more than 30 Business
Days, except to the extent that a longer period is required by applicable law (the “Offer Period”). No later than five
Business Days after the termination of the Offer Period (the “Purchase Date”), UK Holdco will apply all Excess Proceeds
(the “Offer Amount”), to the purchase of Securities and, if applicable, other tendered Indebtedness as provided in
Section 4.06 or, if less than the Offer Amount has been tendered, all Securities and, if applicable, other Indebtedness tendered
in response to the Asset Sale Offer. Payment for any Securities so purchased will be made in the same manner as interest payments are
made.

 

(c)            If
the Purchase Date is on or after an interest record date and on or before the related interest payment date, any accrued and unpaid interest
will be paid to the Person in whose name a Security is registered at the close of business on such record date, and no additional interest
will be payable to Holders who tender Securities pursuant to the Asset Sale Offer.

 

(d)            Upon
the commencement of an Asset Sale Offer, UK Holdco shall send, or cause to be sent, electronically or by first-class mail, or as otherwise
provided in accordance with the procedures of the Depository, a written notice to the Trustee, the Paying Agent and each of the Holders.
The notice will contain all instructions and materials necessary to enable such Holders to tender Securities pursuant to the Asset Sale
Offer. The notice, which will govern the terms of the Asset Sale Offer, will state:

 

(i)            that
the Asset Sale Offer is being made pursuant to this Section 3.09 and Section 4.06 hereof and the length of time the Asset Sale
Offer will remain open;

 

(ii)           the
Offer Amount, the purchase price and the Purchase Date;

 

(iii)          that
Securities not tendered or accepted for payment will continue to accrue interest;

 

(iv)          that,
unless UK Holdco defaults in making such payment, Securities accepted for payment pursuant to the Asset Sale Offer will cease to accrue
interest after the Purchase Date;

 

    -58- 

     

    

 

(v)            that
Holders electing to have Securities purchased pursuant to an Asset Sale Offer may elect to have Securities purchased in minimum denominations
of $2,000 and integral multiples of $1,000 in excess thereof;

 

(vi)            that
Holders electing to have Securities purchased pursuant to any Asset Sale Offer will be required to surrender the Securities, with the
form entitled “Option of Holder to Elect Purchase” attached to the Securities completed, or transfer by book-entry transfer,
to UK Holdco, a depository, if appointed by UK Holdco, or a paying agent at the address specified in the notice at least three days before
the Purchase Date;

 

(vii)           that
Holders will be entitled to withdraw their election if UK Holdco, the Depository or the Paying Agent, as the case may be, receives, not
later than the expiration of the Offer Period, a facsimile transmission or letter setting forth the name of the Holder, the principal
amount of the Securities the Holder delivered for purchase and a statement that such Holder is withdrawing his election to have such Securities
purchased;

 

(viii)          that,
if the aggregate principal amount of Securities and, if applicable, other tendered Indebtedness surrendered by Holders thereof exceeds
the Offer Amount, UK Holdco will select the Securities and, if applicable, other tendered Indebtedness as provided in Section 4.06;
and

 

(ix)            that
Holders whose Securities were purchased only in part will be issued new Securities equal in principal amount to the unpurchased portion
of the Securities surrendered (or transferred by book-entry transfer).

 

(e)            On
or before the Purchase Date, UK Holdco, to the extent lawful, will accept for payment, on a pro rata basis to the extent necessary (subject
to maintenance of authorized denominations), the Offer Amount of Securities or portions thereof and, if applicable, other Indebtedness
tendered pursuant to the Asset Sale Offer or if less than the Offer Amount has been tendered, all Securities and, if applicable, other
Indebtedness tendered, and will deliver or cause to be delivered to the Trustee the Securities properly accepted together with an Officer’s
Certificate stating that such Securities or portions thereof were accepted for payment by UK Holdco in accordance with the terms of this
Section 3.09. UK Holdco, the Depository or the Paying Agent, as the case may be, will, not later than three Business Days after UK
Holdco accepts the Offer Amount, mail or deliver to each tendering Holder an amount equal to the purchase price of the Securities tendered
by such Holder and accepted by UK Holdco for purchase, and UK Holdco will promptly issue a new Security, and the Trustee or Authenticating
Agent, upon receipt of an Authentication Order, will authenticate and mail or deliver (or cause to be transferred by book entry) such
new Security to such Holder, in a principal amount equal to any unpurchased portion of the Security surrendered; provided that
such Security shall be in a minimum principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. Any Securities not
so accepted shall be promptly mailed or delivered by UK Holdco to the Holder thereof. UK Holdco will publicly announce the results of
the Asset Sale Offer on or as soon as practicable after the Purchase Date.

 

(f)            Other
than as specifically provided in this Section 3.09, any purchase pursuant to this Section 3.09 shall be made in accordance with
the provisions of Sections 3.03 through 3.08 hereof and references therein to “redeem,” “redemption” and similar
words shall be deemed to refer to “purchase,” “repurchase” and similar words, as applicable.

 

SECTION 3.10.     [Reserved]

 

    -59- 

     

    

 

SECTION 3.11.     Mandatory
Redemption. Except as provided in Section 3.12, the Issuer is not required to redeem the Securities or make sinking fund
payments with respect to the Securities.

 

SECTION 3.12.     Escrow
of Gross Proceeds; Special Mandatory Redemption

 

(a)            The
Issuer and each of the Holders by acceptance of the Securities hereby authorizes and directs the Trustee to enter into an escrow agreement
(the “Escrow Agreement”) with the Secured Notes Trustee and Citibank, N.A., as escrow agent (the “Escrow Agent”)
and as account bank, pursuant to which the Issuer will deposit (or cause to be deposited) the gross proceeds of the offering of the Securities
into a segregated escrow account pursuant to the Escrow Agreement (the “Escrow Account”). In the Escrow Agreement,
the Issuer will grant to the Trustee for its benefit and the benefit of the Holders, a first priority security interest in the Escrow
Account and all amounts on deposit therein to secure the Obligations under the Securities, which shall automatically be released and terminate
upon disbursement of the property in the Escrow Account in accordance with the Escrow Agreement.

 

(b)            The
Escrow Agreement provides that the Issuer will only be entitled to direct the Escrow Agent to release the funds held in the Escrow Account
in accordance with the terms of the Escrow Agreement. Pursuant to the Escrow Agreement, the Escrow Agent will release funds held in the
Escrow Account (the “Release”) to, or at the order of, the Issuer (the date of such release being referred to as the
 “Escrow Release Date”) upon delivery by the Issuer to the Escrow Agent and the Trustee of an Officer’s Certificate
addressed to the Escrow Agent and the Trustee on or prior to November 8, 2021 (the “Escrow End Date”), certifying
that the Escrow Release Conditions will be met substantially concurrently with or promptly following the Release on the Escrow Release
Date.

 

(c)            In
the event that (A) the Escrow Agent and the Trustee shall not have received the Officer’s Certificate described in Section 3.12(b) on
or prior to the Escrow End Date, (B) the Issuer shall notify the Escrow Agent and the Trustee in writing that in its reasonable judgment
the Escrow Release Conditions will not be satisfied on or prior to the Escrow End Date or (C) the Issuer shall notify the Escrow
Agent and the Trustee in writing that the ProQuest Agreement has been terminated (each such event described in clauses (A), (B) and
(C) above being a “Mandatory Redemption Event”), the Issuer will send a notice of redemption to Holders to redeem
all of the issued and outstanding Securities (the “Special Mandatory Redemption”) at a price (the “Special
Mandatory Redemption Price”) equal to 100% of the principal amount of the outstanding Securities, plus accrued and unpaid interest
from the Issue Date, to, but not including, the date of such redemption (the “Special Mandatory Redemption Date”),
which shall be the third Business Day following the Mandatory Redemption Event (or such date as may be required by the applicable procedures
of the Depository Trust Company). For purposes of determining the Special Mandatory Redemption Date, a Mandatory Redemption Event pursuant
to the preceding sentence shall be deemed to have occurred (x) in the case of clause (A), on the Escrow End Date, and (y) in
the case of clauses (B) and (C), on the date such written notice is delivered to the Escrow Agent and the Trustee (the date of any
such Mandatory Redemption Event, the “Mandatory Redemption Trigger Date”). Pursuant to the Escrow Agreement, within
one Business Day following the Mandatory Redemption Trigger Date, funds will be liquidated and released from the Escrow Account in order
to consummate the Special Mandatory Redemption. In the event that a Mandatory Redemption Event occurs and the amount in the Escrow Account
is not sufficient to fund the Special Mandatory Redemption Price, then the Issuer shall deposit, or cause Public Parent (or one of its
affiliates) to deposit, with the Trustee (or other paying agent for the Special Mandatory Redemption) no later than the close of business
on the second Business Day immediately preceding the Special Mandatory Redemption Date, an amount of cash necessary to fund the Special
Mandatory Redemption Price for the Securities, including accrued and unpaid interest from, and including, the Issue Date to, but excluding,
the Special Mandatory Redemption Date, plus an amount sufficient to pay any fees and expenses of the Trustee that have been incurred and
are payable pursuant to this Indenture and which have been reasonably requested by the Trustee in writing prior to 10:00 am (New York
City time) on the second Business Day immediately preceding the Special Mandatory Redemption Date, provided that the Trustee has received
written notice of the Special Mandatory Redemption on the Mandatory Redemption Trigger Date (and if not, the Issuer shall pay, or cause
Public Parent (or one of its affiliates) to pay, such fees and expenses of the Trustee directly to the Trustee). In addition, the Issuer
shall furnish to the Trustee and the Escrow Agent an Officers’ Certificate setting forth: (i) the provision of this Indenture
pursuant to which the redemption shall occur; (ii) the Special Mandatory Redemption Date; (iii) the Special Mandatory Redemption
Price and (iv) instructions to deliver notice of the Special Mandatory Redemption to Holders, which notice, prepared by the Issuer,
shall contain the same information provided in clauses (i) through (iii) above and which shall be delivered to Holders no later
than the second Business Day immediately preceding the Special Mandatory Redemption Date. In connection with any redemption of the Securities
described in this Section 3.12, the Issuer will deliver, or upon request of the Issuer accompanied by the notice, the Trustee, on
behalf of the Issuer, will deliver electronically or mail to Holders a notice of Special Mandatory Redemption as soon as practicable upon
the occurrence of a Mandatory Redemption Event. Notwithstanding anything to the contrary in this Indenture, any redemption pursuant to
this Section 3.12(c) shall not be subject to the provisions of Sections 3.01 through 3.07 hereof. For the avoidance of doubt,
upon the satisfaction of the Escrow Release Conditions on or prior to the Escrow Release Date and consummation of the Release as provided
in the Escrow Agreement, the Securities shall no longer be subject to Special Mandatory Redemption pursuant to this Section 3.12(c).

 

    -60- 

     

    

 

(d)            By
its acceptance of the Securities, each Holder shall be deemed to authorize and direct the Trustee to enter into and perform its obligations,
if any, under the Escrow Agreement.

 

SECTION 3.13.     Activities
Prior to the Release. Prior to the Escrow Release Date, the primary activities of the Issuer will be restricted to issuing
the Securities and the Secured Notes, issuing capital stock to, and receiving capital contributions from, UK Holdco, Holdings or any
other Parent Holding Company, performing its obligations under the Securities, this Indenture, the Secured Notes, the Secured Notes Indenture,
the Escrow Agreement and the purchase agreement with the Initial Purchasers, performing any obligations under the ProQuest Agreement,
the Release and redeeming the Securities and the Secured Notes, if applicable, and conducting such other activities as are necessary
or appropriate in connection with the Transactions or to carry out the activities described in Sections 3.12.

faith judgment that such event is not material to Holders or the business, assets, operations, financial positions or prospects of UK
Holdco and its Restricted Subsidiaries, taken as a whole; provided, further, however, that no such current report

    -62- 

     

    

 

In connection therewith and for the avoidance of doubt, all such
reports (A) shall not be required to comply with Section 302, Section 404 or Section 906 of the Sarbanes-Oxley Act
of 2002, or related Items 307 or 308 of Regulation S-K promulgated by the SEC, or Item 10(e) of Regulation S-K (with respect
to any non-GAAP financial measures contained therein), (B) shall not be required to contain the separate financial information contemplated
by Rule 3-05, Rule 3-09, Rule 3-10, Rule 3-16, Rule 13-01 or Rule 13-02 of Regulation S-X promulgated by

(b)            All
such annual reports shall be furnished within 90 days after the end of the fiscal year (or such longer period as may be permitted
by the SEC if the Issuer or UK Holdco were then subject to SEC reporting requirements as a non-accelerated domestic filer) to which they
relate, and all such quarterly reports shall be furnished within 45 days after the end of the fiscal quarter (or such longer period

they relate. All such current reports shall be furnished within 10 Business Days after the occurrence of each event that would be required
to be reported in such current report.

 

(c)            The
Issuer shall make available such information and such reports (as well as the details regarding the conference call described below) to
any (i) Holder, (ii) beneficial owner of the Securities, (iii) bona fide prospective investor in the Securities, (iv) bona
fide securities analyst or (v) bona fide market maker in the Securities, in each case, by confidentially posting such information
on its website or on Intralinks or any comparable password-protected online data system and making readily available any password or other
login information to any such recipient. The Trustee shall have no responsibility whatsoever to determine if such posting has occurred.
The Issuer shall hold a quarterly conference call for the Holders and securities analysts to discuss such financial information for the
previous quarter no later than ten Business Days after distribution of such financial information. The Issuer may require an acknowledgement
from any such recipient that (i) it will keep all information confidential, (ii) it will not use such information in violation
of applicable securities laws and (iii) it will not use the information to compete with the Issuer and is not a person principally
engaged in a Similar Business or that derives a significant portion of its revenues from a Similar Business in connection with access
to its financial information or conference calls and may withhold access from any person who does not satisfy such conditions in its good
faith judgment. While the Issuer or any direct or indirect parent of the Issuer is in registration with respect to an initial public offering,
the Issuer or any direct or indirect parent of the Issuer shall not be required to disclose any information or take any actions which,
in the view of the Issuer, would violate securities laws or the SEC’s gun jumping rules and shall not be deemed to have breached
its obligations described in this Indenture by virtue thereof.

to furnishing financial information relating to UK Holdco by furnishing financial information relating to such Reporting Company upon
the filing of reports containing such information with the SEC or other securities commissions or stock exchange; provided, that
if a Reporting Company files such reports with the SEC and such Reporting Company has more than de minimis business operations separate
and apart from its ownership of UK Holdco, then the financial statements of such Reporting Company shall include (or the Issuer shall
otherwise furnish to the Trustee and holders of Securities in accordance with this covenant) a presentation of selected financial metrics
(in UK Holdco’s sole discretion), which need not be audited, that show the difference between the information relating to such Reporting
Company, on the one hand, and the information relating to UK Holdco and its Restricted Subsidiaries on a stand-alone basis, on the other
hand; provided, further, that no such disclosure will be required to be furnished if UK Holdco determines in its good faith judgment
that such disclosure is not material to the Holders. The Trustee will have no responsibility to determine whether such filing has occurred.

 

    -63- 

     

    

 

(e)            The
Issuer shall also furnish to Holders, securities analysts and prospective investors upon request the information required to be delivered
pursuant to Rule 144A(d)(4) under the Securities Act, so long as the Securities are not freely transferable under the Securities
Act.

 

(f)            If
UK Holdco has designated any of its Subsidiaries as an Unrestricted Subsidiary and if any such Unrestricted Subsidiary or group of Unrestricted
Subsidiaries, if taken together as one Subsidiary, would constitute a Significant Subsidiary of UK Holdco, then the annual and quarterly
information required by Section 4.02(a)(1) shall include a presentation of selected financial metrics (in UK Holdco’s
sole discretion), which need not be audited, of such Unrestricted Subsidiaries as a group in the “Management’s Discussion
and Analysis of Financial Condition and Results of Operation.”

 

(g)            Notwithstanding
anything herein to the contrary, the Issuer shall not be deemed to have failed to comply with any of its obligations hereunder for purposes
of Section 6.01(c) until 120 days after the date any report hereunder is due. Notwithstanding anything herein to the contrary,
any failure to comply with this Section 4.02 shall be automatically cured when the Issuer or any direct or indirect parent of the
Issuer, as the case may be, makes available all required reports to the Holders.

 

(h)            Delivery
of reports, information and documents to the Trustee is for informational purposes only and the information and the Trustee’s receipt
of such shall not constitute actual or constructive 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 Officer’s Certificates). The Trustee shall have no duty to review or analyze reports delivered to it.

 

SECTION 4.03.     Limitation
on Incurrence of Indebtedness and Issuance of Disqualified Stock and Preferred Stock.

 

(a)            (i) UK
Holdco shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, Incur any Indebtedness (including
Acquired Indebtedness) or issue any shares of Disqualified Stock; and (ii) UK Holdco shall not permit any of its Restricted Subsidiaries
to issue any shares of Preferred Stock; provided, however, that UK Holdco and any of its Restricted Subsidiaries may Incur
Indebtedness (including Acquired Indebtedness) or issue shares of Disqualified Stock and any of UK Holdco’s Restricted Subsidiaries
may issue shares of Preferred Stock, in each case, if either (x) the Fixed Charge Coverage Ratio of UK Holdco and its Restricted
Subsidiaries for the most recently ended four full fiscal quarters for which internal financial statements are available immediately
preceding the date on which such additional Indebtedness is Incurred or such Disqualified Stock or Preferred Stock is issued would have
been at least 2.00 to 1.00 or (y) the Consolidated Total Debt Ratio of UK Holdco would not exceed 6.50 to 1.00 (any such debt incurred
pursuant to this proviso, “Ratio Debt”), in each case determined on a Pro Forma Basis; provided, further,
however, that the aggregate principal amount of Indebtedness (excluding Acquired Indebtedness not Incurred in connection with
or in contemplation of the applicable merger, acquisition or other similar transaction) that may be Incurred and Disqualified Stock or
Preferred Stock that may be issued pursuant to the foregoing by Restricted Subsidiaries that are not the Issuer or Guarantors of the
Securities shall not exceed the greater of (x) $450.0 million and (y) 39% of LTM EBITDA at any one time outstanding pursuant
to this Section 4.03(a) (less the outstanding amount of any Indebtedness Incurred by Restricted Subsidiaries that are non-Guarantor
Subsidiaries pursuant to Section 4.03(b)(xix)(1).

 

    -64- 

     

    

 

(b)            The
limitations set forth in Section 4.03(a) shall not apply to (collectively, “Permitted Debt”):

 

(i)            the
Incurrence by UK Holdco or its Restricted Subsidiaries of Indebtedness under any Debt Facility (and the issuance and creation of letters
of credit and bankers’ acceptances thereunder (with letters of credit and bankers’ acceptances being deemed to have a principal
amount equal to the face amount thereof)) in an aggregate principal amount not to exceed the sum of:

 

(1)   (A) $2,900.0 million, plus
(B) $350.0 million plus (C) an amount equal to the greater of (x) $1,200.0 million and (y) 100% of LTM EBITDA,
in each case, at any one time outstanding, plus

 

(2)   the maximum amount of Indebtedness
such that on a Pro Forma Basis, either (A) the Consolidated Secured Debt Ratio of UK Holdco does not exceed 6.50 to 1.00 or (B) the
Consolidated First Lien Debt Ratio of UK Holdco does not exceed 5.00 to 1.00 (with any Indebtedness Incurred under Section 4.03(b)(i)(1)(C) hereof
on the date of determination of the Consolidated Secured Debt Ratio or Consolidated First Lien Debt Ratio not being included in the calculation
of Consolidated Secured Debt Ratio or Consolidated First Lien Debt Ratio, as applicable, under this Section 4.03(b)(i)(2) on
such date but not, for the avoidance of doubt, excluded from any such calculation made on any such subsequent date),

 

provided, that (x) any Indebtedness Incurred
and outstanding pursuant to Sections 4.03(b)(i)(1) and (2) shall be deemed to be Indebtedness that is secured by a Lien, whether
or not so secured, solely for purposes of calculating the Consolidated Secured Debt Ratio for Section 4.03(b)(i)(2)(A), (y) any
Indebtedness Incurred and outstanding pursuant to Section 4.03(b)(i)(2)(B) shall be deemed to be Indebtedness secured by a Lien
that ranks pari passu with the Liens securing the Securities, whether or not so secured, solely for the purposes of calculating

under the terms of this Indenture; provided that if such Indebtedness is by its express terms subordinated in right of payment
to the Securities or the Guarantee of such Restricted Subsidiary, as applicable, any such guarantee of such Guarantor with respect to
such Indebtedness shall be subordinated in right of payment to such Guarantor’s Guarantee with respect to the Securities substantially

    -69- 

     

    

 

(c)            For
purposes of determining compliance with this Section 4.03, in the event that an item of Indebtedness, Disqualified Stock or Preferred
Stock (or any portion thereof) meets the criteria of more than one of the categories of Permitted Debt or is entitled to be Incurred
as Ratio Debt, the Issuer shall, in its sole discretion, at the time of Incurrence, divide and/or classify, or at any later time re-divide
and/or reclassify, such item of Indebtedness, Disqualified Stock or Preferred Stock (or any portion thereof) in any manner that complies
with this Section 4.03. With respect to Sections 4.03(b)(iv), (xi), (xxiv) and (xxvii), if at any time that the Issuer would
be entitled to have Incurred any then outstanding item of Indebtedness as Ratio Debt, such item of Indebtedness shall be automatically
reclassified into an item of Indebtedness Incurred as Ratio Debt. Notwithstanding the foregoing, (x) all term loan Indebtedness
under the Credit Agreement outstanding on the Completion Date shall be deemed to have been Incurred pursuant to Section 4.03(b)(i)(1)(A) and
the Issuer shall not be permitted to reclassify all or any portion of such Indebtedness and (y) all Indebtedness under the Credit
Agreement in respect of revolving commitments available on the Completion Date shall be deemed to be Incurred pursuant to Section 4.03(b)(i)(1)(B) and
the Issuer shall not be permitted to reclassify all or any portion of such Indebtedness. The Issuer will also be entitled to divide,
classify or reclassify an item of Indebtedness in more than one of the types of permitted Indebtedness described in Sections 4.03(a) and
(b) without giving pro forma effect to the Indebtedness, Disqualified Stock or Preferred Stock (or any portion thereof) Incurred
pursuant to Section 4.03(b) when calculating the amount of Indebtedness, Disqualified Stock or Preferred Stock (or any portion
thereof) that may be Incurred pursuant to Section 4.03(a).

 

(d)            For
purposes of determining compliance with this Section 4.03, with respect to Indebtedness Incurred under a Debt Facility, reborrowings
of amounts previously repaid pursuant to “cash sweep” provisions or any similar provisions under a Debt Facility that provide
that Indebtedness is deemed to be repaid daily (or otherwise periodically) shall, subject to UK Holdco’s option to elect otherwise
pursuant to Section 4.03(f), only be deemed for purposes of this Section 4.03 to have been Incurred on the date such Indebtedness
was first Incurred and not on the date of any subsequent reborrowing thereof. Accrual of interest, the accretion of accreted value, the
amortization of original issue discount, the payment of interest in the form of additional Indebtedness with the same terms, the payment
of dividends on Disqualified Stock or Preferred Stock in the form of additional shares of Disqualified Stock or Preferred Stock of the
same class, the accretion of liquidation preference and increases in the amount of Indebtedness outstanding solely as a result of fluctuations
in the exchange rate of currencies shall not be deemed to be an Incurrence of Indebtedness, Disqualified Stock or Preferred Stock for
purposes of this Section 4.03. For the avoidance of doubt, the outstanding principal amount of any particular Indebtedness shall
be counted only once, and guarantees of, or obligations in respect of letters of credit relating to, Indebtedness that is otherwise
included in the determination of a particular amount of Indebtedness shall not be included in the determination of such amount of Indebtedness;
provided that the Incurrence of the Indebtedness represented by such guarantee or letter of credit, as the case may be, was in
compliance with this Section 4.03.

 

(e)            For
purposes of determining compliance with any U.S. Dollar-denominated restriction on the Incurrence of Indebtedness, the U.S. Dollar-equivalent
principal amount of Indebtedness denominated in a currency other than U.S. Dollars shall be calculated based on the relevant currency
exchange rate in effect on the date such Indebtedness was Incurred, in the case of term debt, or first committed or first Incurred (whichever
yields the lower U.S. Dollar equivalent), in the case of revolving credit debt; provided that if such Indebtedness is Incurred
to refinance other Indebtedness denominated in a currency other than U.S. Dollars, and such refinancing would cause the applicable U.S.
Dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing,
such U.S. Dollar-denominated restriction shall be deemed not to have been exceeded so long as the principal amount of such refinancing
Indebtedness does not exceed the principal amount of such Indebtedness being refinanced (plus an amount not exceeding the amount otherwise
able to be Incurred pursuant to Section 4.03(b), it being understood that such amount shall constitute utilization of the applicable
basket or exception to this Section 4.03, as the case may be).

 

    -70- 

     

    

 

(f)            In
the event that, pursuant to either Section 4.03(a) or 4.03(b)(i)(2), UK Holdco or its Restricted Subsidiaries enters into or
increases commitments under a revolving credit facility, the Consolidated First Lien Debt Ratio, the Consolidated Secured Debt Ratio
and the Consolidated Total Debt Ratio of UK Holdco, will, for purposes of Section 4.03(a), Section 4.03(b)(i)(2) and clause
(26)(y) of the definition of “Permitted Liens” (solely to the extent the Obligations under such revolving credit facility
are secured by Liens) (collectively, the “Reserved Indebtedness Baskets”), as applicable, at UK Holdco’s option,
as elected on the date such revolving credit commitments are entered into or increased, either (a) be determined on the date such
revolving credit commitments are entered into or increased, in which case the Consolidated First Lien Debt Ratio, Consolidated Secured
Debt Ratio and Consolidated Total Debt Ratio, as applicable, for purposes of calculating compliance with (A) the Consolidated Total
Debt Ratio test set forth in Section 4.03(a), (B) the Consolidated First Lien Debt Ratio and the Consolidated Secured Debt
Ratio test sets forth in Section 4.03(b)(i)(2) and (C) the Consolidated First Lien Debt Ratio, Consolidated Secured Debt
Ratio and Consolidated Total Debt Ratio tests set forth in clause (26)(y) of the definition of “Permitted Liens” (collectively,
the “Reserved Indebtedness Tests”), as applicable, shall be calculated (whether on such date or thereafter (but only
with respect to such portion of commitments that have not been permanently reduced)) assuming that the full amount thereof has been borrowed
as of such date, and, if the applicable Reserved Indebtedness Test is satisfied with respect thereto on such date, any future borrowing
or reborrowing thereunder (and the issuance and creation of letters of credit and bankers’ acceptances thereunder) will be permitted
under the applicable Reserved Indebtedness Basket, in each case irrespective of the Consolidated First Lien Debt Ratio, Consolidated
Secured Debt Ratio or Consolidated Total Debt Ratio, as applicable, at the time of any borrowing or reborrowing (or issuance or creation
of letters of credit or bankers’ acceptances thereunder) (the committed amount permitted to be borrowed or reborrowed (and the
issuance and creation of letters of credit and bankers’ acceptances) on a date pursuant to the operation of this clause (a) shall
be the “Reserved Indebtedness Amount”) or (b) be determined on the date such amount is borrowed pursuant to any
such facility or increased commitment.

(A)            the
principal amount (or accreted value, if applicable) of such new Indebtedness does not exceed the principal amount (or accreted value,

defeased, acquired or retired and (y) the remaining Weighted Average Life to Maturity of the Securities;

 

(iv)            the

Stock or the declaration of such dividends on Refunding Capital Stock that is Preferred Stock, after giving effect to such issuance (and
the payment of dividends or distributions) on a Pro Forma Basis, UK Holdco would be permitted to incur at least $1.00 of additional Ratio
Debt pursuant to the test set forth in Section 4.03(a) and (II) the aggregate amount of dividends declared and paid pursuant
to this clause (vi) does not exceed the net cash proceeds actually received by UK Holdco from any such sale of Designated Preferred

provided, however, that at the time of, and after giving
effect to, any Restricted Payment permitted under Section 4.04(b)(x) and 4.04(b)(xxii), no Event of Default shall have occurred
and be continuing or would occur as a consequence thereof.

 

(c)            UK
Holdco shall not permit any Unrestricted Subsidiary to become a Restricted Subsidiary except pursuant to the definition of “Unrestricted
Subsidiary.” For purposes of designating any Restricted Subsidiary as an Unrestricted Subsidiary, all outstanding Investments by
UK Holdco and its Restricted Subsidiaries (except to the extent repaid prior to the time of designation) in the Subsidiary so designated
shall be deemed to be Restricted Payments or Permitted Investments in an amount determined as set forth in the last sentence of the definition

would be permitted at such time and if such Subsidiary otherwise meets the definition of an Unrestricted Subsidiary.

 

(d)            For
purposes of this Section 4.04, if any Investment or Restricted Payment would be permitted pursuant to one or more provisions described
above and/or one or more of the exceptions contained in the definition of “Permitted Investments,” the Issuer may divide and
classify such Investment or Restricted Payment in any manner that complies with this Section 4.04 and may later divide and reclassify
any such Investment or Restricted Payment so long as the Investment or Restricted Payment (as so divided and/or reclassified) would be
permitted to be made in reliance on the applicable exception as of the date of such reclassification.

Indenture, the Securities, any Additional Securities permitted to be Incurred under this Indenture and in each case any guarantees thereof;

 

(3)            applicable
law or any applicable rule, regulation or order;

 

(4)            any
agreement or other instrument of a Person acquired by UK Holdco or any Restricted Subsidiary which was in existence at the time of such
acquisition or at the time it merges with or into UK Holdco or any Restricted Subsidiary or assumed in connection with the acquisition
of assets from such Person (but not created in contemplation thereof), which encumbrance or restriction is not applicable to any Person,
or the properties or assets of any Person and its Subsidiaries, other than the Person, or the property or assets of the Person and its
Subsidiaries, so acquired or the property or assets so assumed;

 

(5)            contracts
or agreements for the sale of assets, including customary restrictions with respect to a Restricted Subsidiary imposed pursuant to an
agreement entered into for the sale or disposition of all or substantially all the Capital Stock or assets of such Restricted Subsidiary;

 

(6)            Indebtedness
secured by a Lien that is otherwise permitted to be Incurred pursuant to Section 4.03 and Section 4.11 that limit the right
of the debtor to dispose of the assets securing such Indebtedness;

 

(7)            restrictions
on cash or other deposits or net worth imposed by customers under contracts entered into in the ordinary course of business;

leases or licenses of intellectual property) that impose restrictions of the type described in clause (c) above on the property
subject to such lease, license, contract or agreement;

 

(11)          any
encumbrance or restriction of a Receivables Subsidiary effected in connection with a Qualified Receivables Financing; provided,
however, that such restrictions apply only to such Receivables Subsidiary;

(12)            other
Indebtedness, Disqualified Stock or Preferred Stock of UK Holdco or any Restricted Subsidiary that is Incurred subsequent to the Completion
Date pursuant to Section 4.03; provided that either (a) such encumbrances and restrictions contained in any agreement
or instrument will not materially affect the Issuer’s ability to make anticipated principal or interest payment on the Securities
(as determined by the Issuer in good faith) or (b) such encumbrances and restrictions are not materially more restrictive, taken
as a whole, than those contained in this Indenture (with respect to other indentures) or the Credit Agreement outstanding on the Completion
Date (with respect to other credit agreements);

 

(13)            any
Restricted Investment not prohibited by Section 4.04 and any Permitted Investment;

 

(14)            arising

detract from the value of property or assets of UK Holdco or any Restricted Subsidiary thereof in any manner material to UK Holdco or
any Restricted Subsidiary thereof;

 

(15)            existing

(16)            restrictions
or conditions contained in any trading, netting, operating, construction, service, supply, purchase, sale or other agreement to which
UK Holdco or any of its Restricted Subsidiaries is a party entered into in the ordinary course of business; provided that such
agreement prohibits the encumbrance of solely the property or assets of UK Holdco or such Restricted Subsidiary that are the subject of
such agreement, the payment rights arising thereunder or the proceeds thereof and does not extend to any other asset or property of UK
Holdco or such Restricted Subsidiary or the assets or property of any other Restricted Subsidiary; and

 

(17)            any
encumbrances or restrictions of the type referred to in clauses (a), (b) and (c) above imposed by any amendments, modifications,
restatements, renewals, increases, supplements, refundings, replacements or refinancings of the contracts, instruments or obligations
referred to in clauses (1) through (16) above; provided that such amendments, modifications, restatements, renewals,
increases, supplements, refundings, replacements or refinancings are, in the good faith judgment of the Issuer, not materially more restrictive
as a whole with respect to such dividend and other payment restrictions than those contained in the dividend or other payment restrictions
prior to such amendment, modification, restatement, renewal, increase, supplement, refunding, replacement or refinancing.

 

For purposes of determining compliance with this Section 4.05,
(i) the priority of any Preferred Stock in receiving dividends or liquidating distributions prior to dividends or liquidating distributions
being paid on common stock shall not be deemed a restriction on the ability to make distributions on Capital Stock and (ii) the subordination
of loans or advances made to UK Holdco or a Restricted Subsidiary to other Indebtedness Incurred by UK Holdco or any such Restricted Subsidiary
shall not be deemed a restriction on the ability to make loans or advances.

SECTION 4.06.     Asset
Sales.

 

(a)            UK
Holdco shall not, and shall not permit any of its Restricted Subsidiaries to, cause or make an Asset Sale, unless:

 

(1)            UK
Holdco or any of its Restricted Subsidiaries, as the case may be, receives consideration at the time of such Asset Sale at least equal
to the Fair Market Value (as determined in good faith by the Issuer) of the Equity Interests issued or assets sold or otherwise disposed
of; and

 

(2)            except
in the case of a Permitted Asset Swap, at least 75% of the consideration therefor received by UK Holdco or such Restricted Subsidiary,
as the case may be, together with the consideration for all other Asset Sales that have been made since the Existing Notes Issue Date
(on a cumulative basis), is in the form of Cash Equivalents; provided, however, that in the case of Asset Sales involving
the disposition of non-core assets (as determined by UK Holdco in its good faith judgment; provided the value of such non-core
assets does not exceed 50% of the consideration payable in connection with such acquisition) acquired as part of any acquisition after
the Existing Notes Issue Date, only 50% of the consideration therefor, together with the consideration for all other Asset Sales made
pursuant to this proviso since the Existing Notes Issue Date, must be in the form of Cash Equivalents; provided, further,
that the amount of:

 

(i)            any
liabilities (as shown on UK Holdco’s or such Restricted Subsidiary’s most recent balance sheet or in the notes thereto or,
if Incurred, increased or decreased subsequent to the date of such balance sheet, such liabilities that would have been reflected in UK
Holdco’s or such Restricted Subsidiary’s balance sheet or in the notes thereto if such Incurrence, increase or decrease had
taken place on the date of such balance sheet, as reasonably determined in good faith by the Issuer) of UK Holdco or any Restricted Subsidiary
(other than liabilities that are by their terms subordinated to the Securities) that are assumed by the transferee (or a third party on
behalf of the transferee) of any such assets or Equity Interests pursuant to an agreement that releases or indemnifies UK Holdco or such
Restricted Subsidiary (or a third party on behalf of the transferee), as the case may be, from further liability;

 

(ii)           any
notes or other obligations or other securities or assets received by UK Holdco or such Restricted Subsidiary from such transferee that
are converted by UK Holdco or such Restricted Subsidiary into cash within 180 days of the receipt thereof (to the extent of the cash received);

 

(iii)          any
Designated Non-cash Consideration received by UK Holdco or any of its Restricted Subsidiaries in such Asset Sale having an aggregate Fair
Market Value, taken together with all other Designated Non-cash Consideration received pursuant to this clause (iii) that is
at that time outstanding, not to exceed the greater of (x) $275.0 million and (y) 24% of LTM EBITDA, at the time of the receipt
of such Designated Non-cash Consideration (with the Fair Market Value of each item of Designated Non-cash Consideration being measured
at the time received and without giving effect to subsequent changes in value);

 

(iv)          Indebtedness
of any Restricted Subsidiary that is no longer a Restricted Subsidiary as a result of such Asset Sale, to the extent that UK Holdco and
each other Restricted Subsidiary are released from any Guarantee of such Indebtedness in connection with such Asset Sale; and

 

(v)           consideration
consisting of Indebtedness of the Issuer or any Guarantor received from Persons who are not UK Holdco or a Restricted Subsidiary, shall
each be deemed to be Cash Equivalents for the purposes of this Section 4.06.

 

    -81- 

     

    

 

(b)           Within
450 days after UK Holdco’s or any Restricted Subsidiary’s receipt of the Net Cash Proceeds of any Asset Sale, UK Holdco
or such Restricted Subsidiary may apply the Net Cash Proceeds from such Asset Sale, at its option:

 

(i)            to
repay any Secured Indebtedness, including Indebtedness under the Credit Agreement (and, if the Indebtedness repaid is revolving credit
Indebtedness, to correspondingly reduce commitments with respect thereto), the Secured Notes or the Existing Notes;

 

(ii)           to
repay any Indebtedness of the Issuer or any Guarantor that ranks equally in right of payment with the Securities or the relevant Guarantee
(and, if the Indebtedness repaid is revolving credit Indebtedness, to correspondingly reduce commitments with respect thereto); provided
that if the Issuer or any Guarantor shall so reduce such Indebtedness, the Issuer or such Guarantor will equally and ratably reduce Obligations
under the Securities (A) through open-market purchases (provided that such purchases are at or above 100% of the principal
amount thereof), (B) by redeeming Securities if the Securities are then redeemable as provided under Article 3 or (C) by
making an offer (in accordance with the procedures set forth below for an Asset Sale Offer) to all Holders to purchase at a purchase price
equal to 100% of the principal amount thereof, plus accrued and unpaid interest, if any, on the principal amount of the Securities,

 

(iii)          to
make an investment in any one or more businesses (provided that if such investment is in the form of the acquisition of Capital
Stock of a Person, such acquisition results in such Person becoming a Restricted Subsidiary), assets, or property or capital expenditures,
in each case used or useful in a Similar Business,

 

(iv)          to
make an investment in any one or more businesses (provided that if such investment is in the form of the acquisition of Capital
Stock of a Person, such acquisition results in such Person becoming a Restricted Subsidiary), properties or assets that replace the properties
and assets that are the subject of such Asset Sale (“Replacement Assets”),

 

(v)           to
repay Indebtedness of a Restricted Subsidiary that is not a Guarantor (and, if the Indebtedness repaid is revolving credit Indebtedness,
to correspondingly reduce commitments with respect thereto), other than Indebtedness owed to UK Holdco or another Restricted Subsidiary,
or

 

(vi)          any
combination of the foregoing;

 

provided that UK Holdco and its Restricted Subsidiaries shall
be deemed to have complied with Sections 4.06(b)(iii) and (iv) if and to the extent that, within 450 days after the Asset Sale
that generated the Net Cash Proceeds, the Issuer or UK Holdco has entered into and not abandoned or rejected a binding agreement to acquire
the assets or Capital Stock of a Similar Business, make an Investment in Replacement Assets or make a capital expenditure in compliance
with the provision described in Sections 4.06(b)(iii) and (iv) (an “Acceptable Agreement”) with the good
faith expectation that such acquisition, purchase or capital expenditure will be completed within 180 days after the end of such 450-day
period; provided, further, that if any Acceptable Agreement is later cancelled or terminated for any reason after the end
of such 450-day period and before such Net Cash Proceeds are applied, then such Net Cash Proceeds shall constitute Excess Proceeds.

 

    -82- 

     

    

 

Notwithstanding the foregoing, to the extent that
(x) a repatriation or other distribution of any or all of the Net Cash Proceeds of any Asset Sale by a Subsidiary to UK Holdco (and
payment of such amounts by UK Holdco to the Issuer) is prohibited or delayed by applicable local law (including financial assistance and
corporate benefit restrictions and fiduciary and statutory duties of the relevant directors), (y) such distribution would present
a material risk of liability for the applicable Subsidiary or its directors or officers (or gives rise to a material risk of breach of
fiduciary or statutory duties by any director or officers) or (z) a distribution of any or all of the Net Cash Proceeds of any Asset
Sale by a Subsidiary of the Issuer to the Issuer or by any Subsidiary to UK Holdco (and payment of such amounts by UK Holdco to the Issuer)
would reasonably be expected to result in material adverse Tax consequences, as determined by UK Holdco in its sole discretion, the portion
of such Net Cash Proceeds so affected will not be required to be applied in compliance with this Section 4.06 and may be retained
by the applicable Subsidiary; provided that within 450 days of the receipt of such Net Cash Proceeds, UK Holdco shall use commercially
reasonable efforts to permit repatriation of the proceeds that would otherwise be subject to this Section 4.06, if such repatriation
(A) can be effected without violating local law, (B) would not present a material risk as described in clause (y) above
and (C) can be effected without incurring material adverse Tax consequences, and, if such proceeds may be repatriated such proceeds
shall be required to be applied in compliance with this Section 4.06 within such 450-day period, subject to the immediately preceding
paragraph of this Section 4.06(b).

 

Pending the final application of any such Net Cash
Proceeds, UK Holdco or such Restricted Subsidiary may temporarily reduce Indebtedness under a revolving credit facility, if any, or otherwise
invest such Net Cash Proceeds in Cash Equivalents or Investment Grade Securities.

 

Any Net Cash Proceeds from any Asset Sale that are
not applied as provided and within the time period set forth in the immediately preceding paragraphs (it being understood that any portion
of such Net Cash Proceeds used to make an offer to purchase Securities, as described in Section 4.06(b)(ii), shall be deemed to have
been invested whether or not such offer is accepted) will be deemed to constitute “Excess Proceeds.” When the aggregate
amount of Excess Proceeds exceeds $100.0 million, the Issuer shall make an offer to all Holders of the Securities, and if required by
the terms of any Indebtedness of the Issuer or any Guarantor that ranks equally in right of payment with the Securities or the relevant
Guarantee, to the holders of such Indebtedness (an “Asset Sale Offer”), to purchase the maximum principal amount of
Securities and such Indebtedness that is in minimum denominations of at least $2,000 and integral multiples of $1,000 in excess thereof
with respect to the Securities that may be purchased out of the Excess Proceeds at an offer price in cash in an amount equal to 100% of
the principal amount thereof (or, in the event such Indebtedness of the Issuer or any Guarantor that ranks equally in right of payment
with the Securities or the relevant Guarantee was issued with significant original issue discount, 100% of the accreted value thereof),
plus accrued and unpaid interest, if any, but not including, to the date fixed for the closing of such offer, in accordance with
the procedures set forth in this Indenture or the agreement governing such other Indebtedness. The Issuer will commence an Asset Sale
Offer with respect to Excess Proceeds within ten (10) Business Days after the date that Excess Proceeds exceeds $100.0 million by
mailing or electronically sending the notice required pursuant to the terms of this Indenture, with a copy to the Trustee. The Issuer
may satisfy the foregoing obligations with respect to any Net Cash Proceeds from an Asset Sale by making an Asset Sale Offer with respect
to such Net Cash Proceeds prior to the expiration of the relevant 450 days (or such longer period provided above) or with respect to Excess
Proceeds of $100.0 million or less. To the extent that the aggregate amount of Securities and such Indebtedness of the Issuer or any Guarantor
that ranks equally in right of payment with the Securities or the relevant Guarantee tendered pursuant to an Asset Sale Offer is less
than the Excess Proceeds, the Issuer may use any remaining Excess Proceeds (any such amount, “Retained Declined Proceeds”)
for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of Securities or the Indebtedness of the
Issuer or any Guarantor that ranks equally in right of payment with the Securities or the relevant Guarantee surrendered by holders thereof
exceeds the amount of Excess Proceeds, the Issuer shall select or cause to be selected the Securities and the trustee or agent for such
other Indebtedness shall select such other Indebtedness to be purchased on a pro rata basis based on the accreted value or principal amount
of the Securities or such Indebtedness tendered (subject to adjustment so that no Securities in an unauthorized denomination shall remain
outstanding after such purchase). Upon completion of any such Asset Sale Offer, the amount of Excess Proceeds shall be reset at zero.

 

    -83- 

     

    

 

(c)            The
Issuer will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations to the
extent such laws or regulations are applicable in connection with the repurchase of the Securities pursuant to an Asset Sale Offer. To
the extent that the provisions of any securities laws or regulations conflict with the provisions of this Indenture, the Issuer will comply
with the applicable securities laws and regulations and shall be deemed not to have breached its obligations described in this Indenture
by virtue thereof.

 

SECTION 4.07.     Transactions
with Affiliates.

 

(a)            UK
Holdco shall not, and shall not permit any Restricted Subsidiaries of UK Holdco to, directly or indirectly, make any payment to, or sell,

make or amend any transaction or series of transactions, contract, agreement, understanding, loan, advance or guarantee with, or for the
benefit of, any Affiliate of UK Holdco (each of the foregoing, an “Affiliate Transaction”) involving aggregate consideration
in excess of the greater of $75.0 million and 8% of LTM EBITDA, unless:

 

(i)            such
Affiliate Transaction is on terms that are not materially less favorable to UK Holdco or the relevant Restricted Subsidiary than those
that could have been obtained in a comparable transaction by UK Holdco or such Restricted Subsidiary with an unrelated Person; and

 

(ii)            with
respect to any Affiliate Transaction or series of related Affiliate Transactions involving aggregate consideration in excess of the greater
of $100.0 million and 10% LTM EBITDA, the Issuer delivers to the Trustee a resolution adopted in good faith by the majority of the
Board of Directors of the Issuer or any other direct or indirect parent of the Issuer approving such Affiliate Transaction and set forth
in an Officer’s Certificate provided to the Trustee certifying that such Affiliate Transaction complies with clause (i) above.

as a result of such transaction) and (B) any merger or consolidation of UK Holdco or any direct parent company of UK Holdco; provided
that such parent company shall have no material liabilities and no material assets other than cash, Cash Equivalents and the Capital Stock

business purpose;

 

(ii)            (x) Restricted

pursuant to compensatory, benefit and incentive plans and agreements with officers, directors, managers or employees of UK Holdco (or

parent of UK Holdco;

 

(v)            transactions

of Section 4.07(a)(i);

 

(vi)           payments,
loans or advances to employees or consultants or guarantees in respect thereof (or cancellation of loans, advances or guarantees) for
bona fide business purposes in the ordinary course of business;

 

(vii)          any
agreement, instrument or arrangement as in effect as of the Completion Date or any transaction contemplated thereby, or any amendment
thereto (so long as any such amendment is not disadvantageous to the Holders in any material respect when taken as a whole as compared
to the applicable agreement as in effect on the Completion Date as reasonably determined by the Issuer in good faith);

 

(viii)         the
existence of, or the performance by UK Holdco or any of its Restricted Subsidiaries of its obligations under the terms of any stockholders
or similar agreement (including any registration rights agreement or purchase agreement related thereto) to which it is a party as of
the Completion Date, and any amendment thereto or similar transactions, agreements or arrangements which it may enter into thereafter;
provided, however, that the existence of, or the performance by UK Holdco or any of its Restricted Subsidiaries of its obligations
under, any future amendment to any such existing transaction, agreement or arrangement or under any similar transaction, agreement or
arrangement entered into after the Completion Date shall only be permitted by this clause (viii) to the extent that the terms
of any such existing transaction, agreement or arrangement together with all amendments thereto, taken as a whole, or new transaction,
agreement or arrangement are not otherwise more disadvantageous to the Holders in any material respect when taken as a whole as compared
to the original transaction, agreement or arrangement as in effect on the Completion Date;

 

(ix)            (A) transactions
with customers, clients, suppliers or purchasers or sellers of goods or services, in each case in the ordinary course of business and
otherwise in compliance with the terms of this Indenture, which are fair to UK Holdco and its Restricted Subsidiaries in the reasonable
determination of UK Holdco, and are on terms at least as favorable as might reasonably have been obtained at such time from an unaffiliated
party or (B) transactions with joint ventures or Unrestricted Subsidiaries entered into in the ordinary course of business;

 

(x)            any
transaction effected as part of a Qualified Receivables Financing;

by UK Holdco or any of its Restricted Subsidiaries to the Investors made for any financial advisory, financing, underwriting or placement
services or in respect of other investment banking activities, including, without limitation, in connection with acquisitions or divestitures,
which payments are approved by a majority of the Board of Directors of UK Holdco or any direct or indirect parent of UK Holdco in good
faith;

to effect the Transactions;

of its Restricted Subsidiaries with current, former or future officers and employees of UK Holdco or any of its respective Restricted
Subsidiaries and the payment of compensation to officers and employees of UK Holdco or any of its respective Restricted Subsidiaries (including
amounts paid pursuant to employee benefit plans, employee stock option or similar plans), in each case in the ordinary course of business;

 

(xxiii)        transactions
with a Person that is an Affiliate of UK Holdco solely because UK Holdco, directly or indirectly, owns Equity Interests in, or controls,
such Person entered into in the ordinary course of business;

 

(xxiv)        transactions
with Affiliates solely in their capacity as holders of Indebtedness, Equity Interests of UK Holdco or any of its Subsidiaries, so long
as such transaction is with all holders of such class (and there are such non-Affiliate holders) and such Affiliates are treated no more
favorably than all other holders of such class generally;

 

(xxv)         any
agreement that provides customary registration rights to the equity holders of UK Holdco or any direct or indirect parent of UK Holdco
and the performance of such agreements;

to and from and transactions with any joint venture in the ordinary course of business; provided such joint venture is not controlled
by an Affiliate (other than a Restricted Subsidiary) of UK Holdco; and

 

    -86- 

     

    

 

(xxvii)       transactions
between UK Holdco or any of its Restricted Subsidiaries and any Person that is an Affiliate thereof solely due to the fact that a director
of such Person is also a director of the Issuer or any direct or indirect parent of the Issuer; provided, however, that
such director abstains from voting as a director of the Issuer or such direct or indirect parent of the Issuer, as the case may be, on
any matter involving such other Person.

 

SECTION 4.08.     Change
of Control.

 

(a)            Upon
the occurrence of a Change of Control, each Holder shall have the right to require the Issuer to repurchase all or any part of such Holder’s
Securities at a purchase price in cash equal to 101% of the principal amount thereof (the “Change of Control Payment”),
plus accrued and unpaid interest, if any, to, but not including, the date of repurchase (subject to the right of the Holders of
record on the relevant record date to receive interest due on the relevant interest payment date), in accordance with the terms contemplated
in this Section 4.08; provided, however, that notwithstanding the occurrence of a Change of Control, the Issuer shall
not be obligated to purchase any Securities pursuant to this Section 4.08 in the event that it has exercised its right to redeem
such Securities of such Holder in accordance with Article 3 of this Indenture.

 

(b)            Within
30 days following any Change of Control, except to the extent that the Issuer has exercised its right to redeem the Securities in
accordance with Article 3 of this Indenture, the Issuer shall cause a notice to be sent electronically, or, at the Issuer’s
option, mailed by first-class mail or otherwise provided in accordance with the procedures of the Depository (a “Change of Control
Offer”) to each Holder with a copy to the Trustee describing:

 

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

 

(ii)            the
transaction or transactions constitute a Change of Control;

 

(iii)           the
repurchase date (which shall be no earlier than 10 days nor later than 60 days from the date such notice is sent, except if delivered
in advance of the occurrence of such Change of Control in accordance with this Section 4.08); and

 

(iv)           the
instructions determined by the Issuer that a Holder must follow in order to have its Securities purchased; provided, however, if
a Change of Control occurs prior to the Completion Date, the Issuer will not be required to make a Change of Control Offer until after
the Completion Date.

 

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

 

    -87- 

     

    

 

(d)            On
the purchase date, all Securities purchased by the Issuer under this Section 4.08 shall be delivered to the Trustee for cancellation,
and the Issuer shall pay the purchase price plus accrued and unpaid interest to the Holders entitled thereto.

 

(e)            Notwithstanding
the foregoing provisions of this Section 4.08, the Issuer shall not be required to make a Change of Control Offer upon a Change of
Control if 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 Section 4.08(b) applicable to a Change of Control Offer made by the Issuer and purchases all Securities validly
tendered and not withdrawn under such Change of Control Offer. In addition, for the avoidance of doubt, the Issuer will not be required
to make a Change of Control Offer if the Issuer has previously or concurrently with the Change of Control, issued a notice of a full redemption
pursuant to the provisions set forth under Article 3 of this Indenture.

 

(f)            At
the time the Issuer delivers Securities to the Trustee which are to be accepted for purchase, the Issuer shall also deliver an Officer’s
Certificate stating that such Securities are to be accepted by the Issuer pursuant to and in accordance with the terms of this Section 4.08.
A Security shall be deemed to have been accepted for purchase at the time the Trustee or the Paying Agent, directly or through an agent,
mails or delivers payment therefor to the surrendering Holder.

 

(g)            Prior
to any Change of Control Offer, the Issuer shall deliver to the Trustee an Officer’s Certificate stating that all conditions precedent
contained herein to the right of the Issuer to make such offer have been complied with.

 

(h)            The
Issuer shall comply, to the extent applicable, with the requirements of Rule 14(e)-1 of the Exchange Act and any other securities
laws or regulations in connection with the repurchase of Securities pursuant to this Section 4.08. To the extent that the provisions
of any securities laws or regulations conflict with provisions of this Section 4.08, the Issuer shall comply with the applicable
securities laws and regulations and shall not be deemed to have breached its obligations under this Section 4.08 by virtue of such
compliance.

 

(i)            Notwithstanding
the foregoing provisions, a Change of Control Offer may be made in advance of a Change of Control, and conditioned upon such Change of
Control, with a purchase date to occur upon, or within a specified period of time not to exceed 15 days after, the consummation of such
Change of Control.

 

SECTION 4.09.     Compliance
Certificate. UK Holdco shall deliver to the Trustee within 120 days after the end of each fiscal year of UK Holdco an Officer’s
Certificate, the signer of which shall be the principal executive officer, principal accounting officer, principal financial officer
or duly authorized manager or director of UK Holdco, stating that in the course of the performance by the signer of his or her duties
as an officer, manager or director of UK Holdco he or she would normally have knowledge of any Default and whether or not the signer
knows of any Default that occurred during such period. If he or she does, the certificate shall describe the Default, its status and
what action UK Holdco or the Issuer, as applicable, is taking or proposes to take with respect thereto.

 

SECTION 4.10.     Future
Guarantors. Subject to the Guaranty Principles, if, on or after the Completion Date, any Restricted Subsidiary (including any newly
formed, newly acquired or newly redesignated Restricted Subsidiary) other than an Excluded Subsidiary that is not then a Guarantor guarantees
or Incurs any Indebtedness under the Credit Agreement, then UK Holdco shall cause such Restricted Subsidiary to execute and deliver to
the Trustee a supplemental indenture pursuant to which such Subsidiary shall become a Guarantor under this Indenture within 20 Business
Days of the date that such guarantee has been granted pursuant to the Credit Agreement (giving effect to any extension granted by the
collateral agent under the Credit Agreement.

 

    -88- 

     

    

 

SECTION 4.11.     Liens.
UK Holdco shall not, and shall not permit the Issuer or any of UK Holdco’s Restricted Subsidiaries to, directly or indirectly,
create or Incur any Lien (each, a “Subject Lien”) that secures obligations under any Indebtedness on any asset or
property now owned or hereafter acquired (other than Permitted Liens), unless (x) in the case of any Subject Lien securing Subordinated
Indebtedness, the Securities and related Guarantees are secured by a Lien on such asset or property that is senior in priority to such
Subject Lien; and (y) in all other cases, the Securities (or a Guarantee, in the case of Subject Liens on assets or property of
a Restricted Subsidiary that is a Guarantor) are equally and ratably secured with the Obligations secured by such Subject Lien.

 

Notwithstanding the foregoing, any Lien securing
the Securities granted pursuant to the last clause of the preceding paragraph of this Section 4.11 shall provide by its terms that
such Lien shall be automatically and unconditionally released and discharged upon (a) the release and discharge of the Subject Lien
(including any deemed release upon payment in full of all obligations under such Indebtedness (except upon foreclosure or default of such
Indebtedness)), (b) any sale, exchange or transfer to any Person other than the Issuer or any Guarantor of the property or assets
secured by such Subject Lien, or of all of the Capital Stock held by the Issuer or any Guarantor in, or all or substantially all the assets
of, any Guarantor creating such Subject Lien in each case in accordance with the terms of this Indenture, (c) payment in full of
the principal of, and accrued and unpaid interest, if any, on the Securities, or (d) a defeasance or discharge of the Securities
in accordance with the procedures described in Article 8.

 

For purposes of determining compliance with this
Section 4.11, (x) a Lien need not be Incurred solely by reference to one category of Permitted Liens but may be Incurred under
any combination of such categories (including in part under one such category and in part under any other such category) and (y) in
the event that a Lien (or any portion thereof) meets the criteria of one or more of such categories of Permitted Liens, the Issuer shall,
in its sole discretion, divide, classify or may subsequently reclassify at any time such Lien (or any portion thereof) in any manner that
complies with this Section 4.11 and the definition of “Permitted Liens”; provided that any Liens in respect of
Indebtedness Incurred pursuant to Section 4.03(b)(i)(1)(A) shall be deemed to have been Incurred pursuant to clause (26)(x) of
the definition of “Permitted Liens,” and the Issuer shall not be permitted to reclassify all or any portion of such Liens.

 

With respect to any Lien securing Indebtedness that
was permitted to secure such Indebtedness at the time of the Incurrence of such Indebtedness, such Lien shall also be permitted to secure
any Increased Amount of such Indebtedness. The “Increased Amount” of any Indebtedness shall mean any increase in the
amount of such Indebtedness in connection with any accrual of interest, the accretion of accreted value, the amortization of original
issue discount, the payment of interest in the form of additional Indebtedness with the same terms, accretion of original issue discount
or liquidation preference, any fees, underwriting discounts, accrued and unpaid interest, premiums and other costs and expenses incurred
in connection therewith and increases in the amount of Indebtedness outstanding solely as a result of fluctuations in the exchange rate
of currencies or increases in the value of property securing Indebtedness.

 

    -89- 

     

    

 

SECTION 4.12.     Maintenance
of Office or Agency.

 

(a)            The
Issuer shall maintain, in the United States, an office or agency (which may be an office of the Trustee or an affiliate of the Trustee
or Registrar) where Securities may be surrendered for registration of transfer or for exchange and where notices and demands to or upon
the Issuer in respect of the Securities and this Indenture may be served. The Issuer shall give prompt written notice to the Trustee of
the location, and any change in the location, of such office or agency. If at any time the Issuer shall fail to maintain any such required
office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may
be made or served at the corporate trust office of the Trustee as set forth in Section 12.02.

 

(b)            The
Issuer may also from time to time designate one or more other offices or agencies where the Securities may be presented or surrendered
for any or all such purposes and may from time to time rescind such designations. The Issuer shall give prompt written notice to the Trustee
of any such designation or rescission and of any change in the location of any such other office or agency; provided that no office
or agency of the Trustee shall be an office or agency of the Issuer for purposes of service of legal process against the Issuer or any
Guarantor.

 

(c)            The
Issuer hereby designates the corporate trust office of the Trustee or its agent as such office or agency of the Issuer in accordance with
Section 2.04.

 

SECTION 4.13.     Suspension
of Covenants.

 

(a)            If
on any date following the Completion Date (i) the Securities have Investment Grade Ratings from both Rating Agencies and (ii) no
Default has occurred and is continuing under this Indenture (the occurrence of the events described in the foregoing clauses (i) and
(ii) being collectively referred to as a “Covenant Suspension Event”), UK Holdco and its Restricted Subsidiaries
shall not be subject to Section 4.03, Section 4.04, Section 4.05, Section 4.06, Section 4.07, Section 4.10,
Section 5.01(a)(iv), Section 5.01(b)(iv) and Section 5.01(c)(iv) (collectively, the “Suspended Covenants”).

 

(b)            In
the event that UK Holdco and its Restricted Subsidiaries are not subject to the Suspended Covenants under this Indenture for any period
of time as a result of the foregoing, and on any subsequent date (the “Reversion Date”) one or both of the Rating Agencies
withdraw their Investment Grade Rating or downgrade the rating assigned to the Securities below an Investment Grade Rating, then UK Holdco
and its Restricted Subsidiaries shall thereafter again be subject to the Suspended Covenants under this Indenture with respect to future
events.

 

(c)            The
period of time between the occurrence of a Covenant Suspension Event and the Reversion Date is referred to as the “Suspension
Period.” Additionally, upon the occurrence of a Covenant Suspension Event, the amount of Excess Proceeds from Net Cash Proceeds
shall be reset at zero.

 

(d)            In
the event of any such reinstatement on a Reversion Date, no action taken or omitted to be taken by UK Holdco or any of its Restricted
Subsidiaries prior to such Reversion Date (and no action taken or omitted to be taken following a Reversion Date in connection with honoring,
complying with or otherwise performing or consummating any contractual commitments or obligations entered into during a Suspension Period)
shall give rise to a Default or Event of Default under this Indenture with respect to any Securities; provided that (1) with
respect to Restricted Payments made after any such reinstatement, the amount of Restricted Payments made shall be calculated as though

would have been in effect during such period and (2) all Indebtedness Incurred, or Disqualified Stock or Preferred Stock issued,
during the Suspension Period shall be classified as having been Incurred or issued pursuant to Section 4.03(b)(iii). In addition,

of UK Holdco during the Suspension Period prior to such Reversion Date shall be deemed to have been entered into on or prior to the Completion

DEFAULTS AND REMEDIES

 

SECTION 6.01.     Events
of Default. An “Event of Default” occurs if:

 

(a)            a
default occurs in any payment of interest, if any, on any Security when the same becomes due and payable, and such default continues for

default occurs in the payment of principal or premium, if any, of any Security when due at its Stated Maturity, upon optional redemption,

UK Holdco or any Restricted Subsidiary of UK Holdco fails to comply with any of its agreements contained in the Securities or this Indenture
(other than those referred to in (a) or (b) above) and such failure continues for 60 days after receipt of a related written
Notice of Default as specified below,

 

(d)            Holdings,
UK Holdco, the Issuer or any Significant Subsidiary of UK Holdco fails to pay any Indebtedness (other than Indebtedness owing to Holdings,
UK Holdco or a Restricted Subsidiary) within any applicable grace period after final maturity or the acceleration of any such Indebtedness
by the holders thereof because of a default, in each case, if the total amount of such Indebtedness unpaid or accelerated exceeds $125.0 million
or its foreign currency equivalent,

 

(e)            Holdings,
UK Holdco, the Issuer or any Significant Subsidiary of UK Holdco pursuant to or within the meaning of any Bankruptcy Law:

 

(i)              commences

(ii)             consents

(iv)            makes

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

 

(i)              is
for relief against Holdings, UK Holdco, the Issuer or any Significant Subsidiary of UK Holdco in an involuntary case;

 

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

 

(iii)            orders
the winding up or liquidation of Holdings, UK Holdco, the Issuer or any Significant Subsidiary of UK Holdco;

 

or any similar relief is granted under any foreign laws

(g)           Holdings,

-97-

     

    

 

(i)            [reserved];

 

(j)            [reserved];
or

 

(k)           the
Issuer fails to consummate the Special Mandatory Redemption to the extent required pursuant to Section 3.12(c).

 

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

 

The term “Bankruptcy Law” means
any law relating to bankruptcy, insolvency, receivership, winding-up, liquidation, reorganization or relief of debtors or any amendment
to, succession to or change in any such law, including, without limitation (i) bankruptcy laws of Luxembourg, (ii) Title 11,
United States Code (as amended from time to time), (iii) the Insolvency Act of 1986 of the United Kingdom (as amended from time
to time), or (iv) any similar law for the relief of debtors in any other jurisdiction applicable to Holdings, UK Holdco, the Issuer
or any Significant Subsidiary of UK Holdco. The term “Custodian” means any receiver, trustee, assignee, liquidator,
custodian, administrator, administrative receiver, manager, or similar official under any Bankruptcy Law.

 

A Default under clauses (c), (d), (g) and
(i) above shall not constitute an Event of Default until the Trustee notifies the Issuer in writing or the Holders of at least 30%
of the aggregate principal amount of the outstanding Securities notify the Issuer and the Trustee in writing of the Default and the Issuer
does not cure such Default within the time specified in clauses (c), (d), (g) and (i) above, as applicable, after receipt
of such notice. provided that a notice of Default must specify the Default, demand that it be remediated and state that such notice
is a “Notice of Default.” A notice of Default may not be given with respect to any action taken, and reported publicly or
to Holders of the Securities, more than two years prior to such notice of Default. Any notice of Default, notice of acceleration or instruction
to the Trustee to provide a notice of Default, notice of acceleration or take any other action (a “Noteholder Direction”)
provided by any one or more Holders (each a “Directing Holder”) must be accompanied by a written representation from
each such Holder delivered to the Issuer and the Trustee that such Holder is not (or, in the case such holder is DTC or its nominee,
that such Holder is being instructed solely by beneficial owners that are not) Net Short (a “Position Representation”),
which representation, in the case of a Noteholder Direction relating to the delivery of a notice of Default (a “Default Direction”)
shall be deemed a continuing representation until the resulting Event of Default is cured or otherwise ceases to exist or the Securities
are accelerated. In addition, each Directing Holder is deemed, at the time of providing a Noteholder Direction, to covenant to provide
the Issuer with such other information as the Issuer may reasonably request from time to time in order to verify the accuracy of such
Holder’s Position Representation within five Business Days of request therefor (a “Verification Covenant”).
In any case in which the holder is DTC or its nominee, any Position Representation or Verification Covenant required hereunder shall
be provided by the beneficial owner of the Securities in lieu of DTC or its nominee and DTC shall be entitled to conclusively rely on
such Position Representation and Verification Covenant in delivering its direction to the Trustee.

 

    
-98-

     

    

 

If, following the delivery of a Noteholder Direction,
but prior to acceleration of the Securities, the Issuer determines in good faith that there is a reasonable basis to believe a Directing
Holder was, at any relevant time, in breach of its Position Representation and provides to the Trustee an Officer’s Certificate
stating that the Issuer has initiated litigation with a court of competent jurisdiction seeking a determination that such Directing Holder
was, at such time, in breach of its Position Representation, and seeking to invalidate any Default, Event of Default or acceleration
(or notice thereof) that resulted from the applicable Noteholder Direction, the cure period with respect to such Default shall be automatically
stayed and the cure period with respect to such Event of Default shall be automatically reinstituted and any remedy stayed pending a
final and non-appealable determination of a court of competent jurisdiction on such matter if, without the participation of such Holder,
the percentage of Securities held by the remaining Holders that provided such Noteholder Direction would have been insufficient to validly
provide such Noteholder Direction. If, following the delivery of a Noteholder Direction, but prior to acceleration of the Securities,
the Issuer provides to the Trustee an Officer’s Certificate stating that a Directing Holder failed to satisfy its Verification
Covenant, the cure period with respect to such Default shall be automatically stayed and the cure period with respect to any Event of
Default that resulted from the applicable Noteholder Direction shall be automatically reinstituted and any remedy stayed pending satisfaction
of such Verification Covenant. Any breach of the Position Representation shall result in such Holder’s participation in such Noteholder
Direction being disregarded; and, if, without the participation of such Holder, the percentage of Securities held by the remaining Holders
that provided such Noteholder Direction would have been insufficient to validly provide such Noteholder Direction, such Noteholder Direction
shall be void ab initio (other than any indemnity such Directing Holder may have offered the Trustee), with the effect that such
Event of Default shall be deemed never to have occurred, any acceleration voided and the Trustee shall be deemed not to have received
such Noteholder Direction or any notice of such Default or Event of Default.

 

Notwithstanding anything in the preceding two paragraphs
to the contrary, any Noteholder Direction delivered to the Trustee in connection with a Default under clauses (c), (d), (g), (i) or
(k), during the pendency of an Event of Default under clauses (e) or (f) as a result of proceeding under Bankruptcy Law shall
not require compliance with the two immediately preceding paragraphs.

 

For the avoidance of doubt, the Trustee shall be
entitled to conclusively rely on any Noteholder Direction delivered to it in accordance with the Indenture, shall have no duty to inquire
as to or investigate the accuracy of any Position Representation, enforce compliance with any Verification Covenant, verify any statements
in any Officer’s Certificate delivered to it, or otherwise make calculations, investigations or determinations with respect to
Derivative Instruments, Net Shorts, Long Derivative Instruments, Short Derivative Instruments or otherwise. The Trustee shall have no
liability to the Issuer, any Holder or any other Person in acting in good faith on a Noteholder Direction.

 

The Issuer shall deliver to the Trustee, within
30 days after the occurrence thereof, written notice of any event which is, or with the giving of notice or the lapse of time or both
would become, an Event of Default, its status and what action the Issuer is taking or proposes to take with respect thereto.

 

Any time period in the Indenture to cure any actual
or alleged Default or Event of Default may be extended or stayed by a court of competent jurisdiction.

 

SECTION 6.02.        Acceleration.
If an Event of Default (other than an Event of Default specified in Section 6.01(e) or (f) with respect to the Issuer)
occurs and is continuing, the Trustee by written notice to the Issuer or the Holders of at least 30% of the aggregate principal amount
of outstanding Securities by written notice to the Issuer and the Trustee, may declare the principal of, premium, if any, and accrued
but unpaid interest, if any, on all the Securities to be due and payable. Upon such a declaration, such principal and interest, if any,
shall be due and payable immediately. If an Event of Default specified in Section 6.01(e) or (f) with respect to the Issuer
occurs, the principal of, premium, if any, and interest on all the Securities shall ipso facto become and be immediately due and payable
without any declaration or other act on the part of the Trustee or any Holders. The Holders of a majority in principal amount of the
outstanding Securities by notice to the Trustee may rescind an acceleration and its consequences if the rescission would not conflict
with any judgment or decree and if all existing Events of Default have been cured or waived except nonpayment of principal or interest
that has become due solely because of acceleration. No such rescission shall affect any subsequent Default or impair any right consequent
thereto.

In the event of any Event of Default specified in
Section 6.01(d), such Event of Default and all consequences thereof (including, without limitation, the declaration of acceleration
of the Securities) shall be annulled, waived and rescinded, automatically and without any action by the Trustee or the Holders, if within
20 days after such Event of Default arose the Issuer delivers an Officer’s Certificate to the Trustee stating that (x) the
Indebtedness or guarantee that is the basis for such Event of Default has been discharged or (y) the holders thereof have rescinded
or waived the acceleration, default, notice or action (as the case may be) giving rise to such Event of Default or (z) the default
or acceleration that is the basis for such Event of Default has been cured or waived, it being understood that in no event shall an acceleration
of the principal amount of the Securities as described above be annulled, waived or rescinded upon the happening of any such events.

 

SECTION 6.03.        Other
Remedies. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy at law or in equity to collect
the payment of principal of or interest on the Securities or to enforce the performance of any provision of the Securities or this Indenture.

 

The Trustee may maintain a proceeding even if it
does not possess any of the Securities or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder
in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or
acquiescence in the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative to the extent
permitted by law.

 

SECTION 6.04.        Waiver
of Past Defaults. Provided the Securities are not then due and payable by reason of a declaration of acceleration, the Holders of
a majority in principal amount of the Securities by notice to the Trustee may waive an existing Default or Event of Default and its consequences
except (a) a Default or Event of Default in the payment of the principal of or interest on a Security or (b) a Default or Event
of Default in respect of a provision that under Section 9.02 cannot be amended without the consent of each Holder affected. When
a Default is waived, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured
for every purpose of this Indenture, but no such waiver shall extend to any subsequent or other Default or impair any consequent right.

 

SECTION 6.05.        Control
by Majority. The Holders of a majority in principal amount of the Securities then outstanding may direct the time, method and place
of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee. However,
the Trustee may refuse to follow any direction that conflicts with law or this Indenture or, subject to Section 7.01, that the Trustee
determines is unduly prejudicial to the rights of any other Holder (it being understood that the Trustee has no affirmative duty to ascertain
whether or not any action or forbearance is unduly prejudicial to such Holders) or that would involve Trustee in personal liability;
provided, however, that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with
such direction. Prior to taking any action under this Indenture, the Trustee shall be entitled to indemnification and/or security (which
may include pre-funding) satisfactory to it against all losses, liabilities and expenses caused by taking or not taking such action.

SECTION 6.06.        Limitation
on Suits.

 

(a)           Except
to enforce the right to receive payment of principal, premium, if any, or interest when due, no Holder may pursue any remedy with respect
to this Indenture or the Securities unless:

 

(i)            the
Holder gives to the Trustee written notice stating that an Event of Default is continuing;

 

(ii)           the
Holders of at least 30% of the aggregate principal amount of the Securities then outstanding make a written request to the Trustee to
pursue the remedy;

 

(iii)          such
Holder or Holders offer, and if required, provide to the Trustee security and/or indemnity (which may include pre-funding) satisfactory
to it against any loss, liability or expense;

 

(iv)         the
Trustee does not comply with the request within 60 days after receipt of the request and the offer of security or indemnity; and

 

(v)          the
Holders of a majority in principal amount of the outstanding Securities do not give the Trustee a direction inconsistent with the request
during such 60-day period.

 

(b)          A
Holder may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over another Holder
(it being understood that the Trustee has no affirmative duty to ascertain whether or not such actions are unduly prejudicial to such
Holders).

 

SECTION 6.07.        Rights
of the Holders to Receive Payment. Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment
of principal of and interest on the Securities held by such Holder, on or after the respective due dates expressed or provided for in
the Securities, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or
affected without the consent of such Holder; provided that a Holder shall not have the right to institute any such suit for the
enforcement of payment if and to the extent that the institution or prosecution thereof or the entry of judgment therein would, under
applicable law, result in the surrender, impairment, waiver or loss of the Lien of this Indenture upon any property subject to such Lien.

 

SECTION 6.08.       Collection
Suit by Trustee. If an Event of Default specified in Section 6.01(a) or (b) occurs and is continuing, the Trustee
may recover judgment in its own name and as trustee of an express trust against the Issuer or any other obligor on the Securities for
the whole amount then due and owing (together with interest on overdue principal and (to the extent lawful) on any unpaid interest at
the rate provided for in the Securities) and the amounts provided for in Section 7.06.

 

SECTION 6.09.       Trustee
May File Proofs of Claim. The Trustee may file such proofs of claim and other papers or documents and take such action as may
be necessary or advisable in order to have the claims of the Trustee (including any claim for reasonable compensation, expenses disbursements
and advances of the Trustee (including counsel, accountants, experts or such other professionals as the Trustee deems reasonably necessary,
advisable or appropriate)) and the Holders allowed in any judicial proceedings relative to the Issuer or any Guarantor, their creditors
or their property, shall be entitled to participate as a member, voting or otherwise, of any official committee of creditors appointed
in such matters and, unless prohibited by law or applicable regulations, may vote on behalf of the Holders in any election of a trustee
in bankruptcy or other Person performing similar functions, and any Custodian in any such judicial proceeding is hereby authorized by
each Holder to make payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly
to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the
Trustee and its agents and counsel, and any other amounts due the Trustee under Section 7.06 and 10.08.

 

    
-101-

     

    

 

No provision of this Indenture shall be deemed to
authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement,
adjustment or composition affecting the Securities or the rights of any Holder thereof or to authorize the Trustee to vote in respect
of the claim of any Holder in any such proceeding.

 

SECTION 6.10.        Priorities.
Subject to the Notes Documents, if the Trustee collects any money or property pursuant to this Article 6, it shall pay out the money
or property in the following order:

 

FIRST: to the Trustee for amounts due
to it under this Indenture;

 

SECOND: to Holders for amounts due and
unpaid on the Securities for principal, premium, if any, and interest, ratably, without preference or priority of any kind, according
to the amounts due and payable on the Securities for principal and interest, respectively; and

 

THIRD: to the Issuer or, to the extent
the Trustee collects any amount for any Guarantor, to such Guarantor.

 

The Trustee, upon prior written notice to the Issuer
and the Guarantors, may fix a record date and payment date for any payment to the Holders pursuant to this Section 6.10. At least
15 days before such record date, the Trustee shall send to each Holder and the Issuer a notice that states the record date, the
payment date and amount to be paid.

 

SECTION 6.11.        Undertaking
for Costs. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any
action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking
to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees
and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by
the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.07
or a suit by Holders of more than 10% in principal amount of the Securities then outstanding.

 

SECTION 6.12.        Waiver
of Stay or Extension Laws. Neither the Issuer nor any Guarantor (to the extent it may lawfully do so) shall at any time insist upon,
or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at
any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Issuer and each Guarantor (to
the extent that it may lawfully do so) hereby expressly waive all benefit or advantage of any such law, and shall not hinder, delay or
impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as though
no such law had been enacted.

 

SECTION 6.13.        Restoration
of Rights and Remedies. If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy under this Indenture
and such proceeding has been discontinued or abandoned for any reason, or has been determined adversely to the Trustee or to such Holder,
then and in every such case, subject to any determination in such proceeding, the Issuer, any Guarantor, the Trustee and the Holders
shall be restored severally and respectively to their former positions hereunder and thereafter all rights and remedies of the Trustee
and the Holders shall continue as though no such proceeding had been instituted.

 

    
-102-

     

    

 

SECTION 6.14.        Rights
and Remedies Cumulative. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or
stolen Securities in Section 2.08 hereof, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders
is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative
and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion
or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate
right or remedy.

 

SECTION 6.15.        Delay
or Omission Not Waiver. No delay or omission of the Trustee or of any Holder to exercise any right or remedy accruing upon any Event
of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every
right and remedy given by this Article 6 or by law to the Trustee or to the Holders may be exercised from time to time, and as often
as may be deemed expedient, by the Trustee or by the Holders, as the case may be.

TRUSTEE

 

SECTION 7.01.        Duties
of Trustee.

 

(a)           If
an Event of Default has occurred and is continuing and a Trust Officer of the Trustee has actual knowledge of such Event of Default,
the Trustee shall exercise the rights and powers vested in it by this Indenture and use the same degree of care and skill in its exercise
as a prudent person would exercise or use under the circumstances in the conduct of such person’s own affairs.

 

(b)           Except
during the continuance of an Event of Default actually known to a Trust Officer of the Trustee:

 

(i)            the
Trustee undertakes to perform such duties and only such duties as are specifically set forth in this Indenture and no implied covenants
or obligations shall be read into this Indenture against the Trustee; and

 

(ii)           in
the absence of bad faith on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the
opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture.
However, in the case of certificates or opinions required by any provision hereof to be provided to it, the Trustee shall examine the
certificates and opinions to determine whether or not they conform to the form requirements of this Indenture (but need not confirm or
investigate the accuracy of mathematical calculations or other facts stated therein).

 

(c)          The
Trustee may not be relieved from liability for its own negligent action, its own negligent failure to act or its own willful misconduct,
except that:

 

(i)            this
Section 7.01(c) does not limit the effect of Section 7.01(b);

 

    
-103-

     

    

 

(ii)           the
Trustee shall not be liable for any error of judgment made in good faith by a Trust Officer unless it is proved that the Trustee was
negligent in ascertaining the pertinent facts;

 

(iii)          the
Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received
by it pursuant to Section 6.05; and

 

(iv)          no
provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur liability in the performance
of any of its duties hereunder or to take or omit to take any action under this Indenture or take any action at the request or direction
of Holders if it has grounds for believing that repayment of such funds is not assured to it or it does not receive an agreement in writing
from the Holders for indemnity and/or security and/or prefunding satisfactory to it in its discretion against any loss, liability or
expense which might be incurred by it in compliance with such request or direction nor shall the Trustee be required to do anything which
is illegal or contrary to applicable laws or this Indenture. The Trustee will not be liable to the Holders if prevented or delayed in
performing any of its obligations or discretionary functions under this Indenture by reason of any present or future law applicable to
it, by any governmental or regulatory authority or by any circumstances beyond its control.

 

(d)          The
Trustee shall not be liable for interest on any money received by it except as the Trustee may agree in writing with the Issuer.

 

(e)           Money
held in trust by the Trustee need not be segregated from other funds except to the extent required by law.

 

(f)            Every
provision of this Indenture relating to the conduct or affecting the liability of or affording protection to the Trustee shall be subject
to the provisions of this Section 7.01.

 

(g)          The
Trustee shall not be deemed to have notice or any knowledge of any matter (including without limitation Defaults or Events of Default)
unless a Trust Officer assigned to this Indenture and working in the Trustee’s corporate trust and agency department has actual
knowledge thereof or unless written notice thereof is received by the Trustee in accordance with the terms of this Indenture and such
notice clearly references the Securities, the Issuer or this Indenture.

 

(h)          The
Trustee will (save as expressly otherwise provided herein) have absolute and uncontrolled discretion as to the exercise or non-exercise
of its functions and will not be responsible for any loss, liability, cost, claim, action, demand, expense or inconvenience which may
result from their exercise or non-exercise but, whenever the Trustee is under the provisions of this Indenture or the Securities bound
to act at the request or direction of the Holders, the Trustee shall nevertheless not be so bound unless first indemnified and/or secured
and/or prefunded to its satisfaction against all actions, proceedings, claims and demands to which it may render itself liable and all
costs, charges, damages, expenses and liabilities which it may incur by so doing.

 

SECTION 7.02.        Rights
of Trustee.

 

(a)           The
Trustee may refrain from taking any action in any jurisdiction if the taking of such action in that jurisdiction would, in its opinion,
based upon legal advice in the relevant jurisdiction, be contrary to any law of that jurisdiction or, to the extent applicable, the State
of New York. Furthermore, the Trustee may also refrain from taking such action if such action would otherwise render it liable to any
person in that jurisdiction, the State of New York or if, in its opinion based upon such legal advice, it would not have the power to
take such action in that jurisdiction by virtue of any applicable law in that jurisdiction, in the State of New York or if it is determined
by any court or other competent authority in that jurisdiction, in the State of New York that it does not have such power.

 

    
-104-

     

    

 

(b)           The
Trustee may conclusively rely on and be protected in acting or refraining to act based on any document believed by it to be genuine and
to have been signed or presented by the proper person. The Trustee need not investigate any fact or matter stated in the document.

 

(c)           Before
the Trustee acts or refrains from acting, it may require an Officer’s Certificate or an Opinion of Counsel or both. The Trustee
shall not be liable for any action it takes or omits to take in good faith in reliance on the Officer’s Certificate or Opinion
of Counsel.

 

(d)           The
Trustee may act through agents and shall not be responsible for the misconduct or negligence of any agent appointed with due care.

 

(e)           The
Trustee shall not be liable for any action it takes or omits to take in good faith which it reasonably believes to be authorized or within
its rights or powers; provided, however, that the Trustee’s conduct, as applicable, does not constitute willful misconduct
or gross negligence.

 

(f)           The
Trustee may consult with counsel of its own selection at the expense of the Issuer and the advice or opinion of counsel with respect
to legal matters relating to this Indenture and the Securities shall be full and complete authorization and protection from liability
in respect of any action taken, omitted or suffered by it hereunder in good faith and in accordance with the advice or opinion of such
counsel.

 

(g)           The
Trustee shall not be bound to make any investigation into the facts or matters stated in any Officer’s Certificate, Opinion of
Counsel, resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, approval, bond, debenture,
note or other paper or document, but the Trustee, in its discretion, may each make such further inquiry or investigation into such facts
or matters as it may see fit.

 

(h)           The
Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction
of any of the Holders pursuant to this Indenture, unless such Holders shall have offered, and if requested, provided to the Trustee indemnity
and/or security (which may include pre-funding) satisfactory to the Trustee against all losses, liabilities and expenses which might
be Incurred by it in compliance with such request or direction.

 

(i)            In
the event the Trustee receives inconsistent or conflicting requests and indemnity from two or more groups of Holders, each representing
less than the requisite majority in aggregate principal amount of the Securities then outstanding, pursuant to the provisions of this
Indenture, the Trustee, in its sole discretion, may determine what action, if any, shall be taken and shall be held harmless and shall
not incur any liability for its failure to act until such inconsistency or conflict is, in its opinion, resolved, and absent willful
misconduct or negligence, the Trustee shall not be liable for acting in good faith on instructions believed by them to be genuine and
from the proper party.

 

(j)            The
Trustee shall not have any obligation or duty to monitor, determine or inquire as to compliance, and shall not be responsible or liable
for compliance with restrictions on transfer, exchange, redemption, purchase or repurchase, as applicable, of minimum denominations imposed
under this Indenture or under applicable law or regulation with respect to any transfer, exchange, redemption, purchase or repurchase,
as applicable, of any interest in any Securities, but may at its sole discretion, choose to do so.

 

    
-105-

     

    

 

(k)           The
permissive rights of the Trustee to take the actions permitted by this Indenture will not be construed as an obligation or duty to do
so.

 

(l)            Except
with respect to Section 4.01 hereof, and provided it or an affiliate of it is acting as a Paying Agent, the Trustee shall have no
duty to inquire as to the performance of UK Holdco or the Issuer with respect to the covenants contained in Article 4 hereof. The
Trustee may assume without inquiry in the absence of written notice to the contrary that UK Holdco and the Issuer are duly complying
with its obligations contained in this Indenture required to be performed and observed by it, and that no Default or Event of Default
or other event which would require repayment of the Securities has occurred.

 

(m)          The
Trustee may, in the execution and exercise of all or any of the trusts, powers, authorities and discretions vested in it by this Indenture,
delegate to any person or persons all or any of the trusts, powers, authorities and discretions vested in it by this Indenture and any
such delegation may be made upon such terms and conditions and subject to such regulations as the Trustee may think fit. The Trustee
shall not be under any obligation to supervise the activities of such delegates and shall not be responsible for the misconduct or negligence
of such delegates, or for any costs, expenses, losses or liabilities of, or caused by, such delegates, provided that such delegation
of such delegates has been made with due care.

 

(n)          The
rights, privileges, protections, immunities and benefits given to the Trustee, including its right to be indemnified and/or secured (including
by way of pre-funding) are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and to each agent,
any custodian and any other Person employed to act hereunder. The Trustee shall not be liable for acting in good faith or instructions
believed to be genuine and from the proper party.

 

(o)           In
no event shall the Trustee, including as the Paying Agent, Registrar or in any other capacity hereunder, be liable under or in connection
with this Indenture for indirect, special, incidental, punitive or consequential losses or damages of any kind whatsoever, including
but not limited to lost profits, whether or not foreseeable, even if the Trustee, including as the Paying Agent, Registrar or in any
other capacity hereunder has been advised of the possibility thereof and regardless of the form of action in which such damages are sought.

 

(p)          The
Trustee may request that the Issuer deliver a certificate setting forth the names of individuals and/or titles of officers authorized
at such time to take specified actions pursuant to this Indenture.

 

(q)          The
Trustee shall not be required to give any bond or surety in respect of the performance of its powers and duties hereunder.

 

SECTION 7.03.        Individual
Rights of Trustee. The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise
deal with and collect obligations owed to it by the Issuer or its Affiliates with the same rights it would have if it were not Trustee.
Any Paying Agent or Registrar may do the same with like rights.

 

SECTION 7.04.       Trustee’s
Disclaimer. The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture,
any Guarantee, the Escrow Agreement or the Securities, it shall not be accountable for the Issuer’s use of the proceeds from the
Securities and it shall not be responsible for any statement of the Issuer or any Guarantor in this Indenture, the Escrow Agreement or
in any document issued in connection with the sale of the Securities or in the Securities other than the Trustee’s certificate
of authentication. The Trustee shall not be charged with knowledge of any Default or Event of Default or of the identity of any Significant
Subsidiary unless either (a) a Trust Officer shall have actual knowledge thereof or (b) the Trustee shall have received written
notice thereof in accordance with Section 12.02 from the Issuer, any Guarantor or any Holder, and such notice references the Securities
and this Indenture.

 

    
-106-

     

    

 

SECTION 7.05.       Notice
of Defaults. If a Default or Event of Default occurs and is continuing and if a Trust Officer has actual knowledge thereof, the Trustee
shall mail by first-class mail to each Holder at the address set forth in the register, notice of the Default or Event of Default within
90 days after it is actually known to a Trust Officer. Except in the case of a Default or Event of Default in payment of principal
of, premium (if any), interest on any Securities (including payments pursuant to the optional redemption or required repurchase provisions
of such Securities), the Trustee may withhold the notice if and so long as the Trustee in good faith determines that withholding the
notice is in the interests of Holders.

 

SECTION 7.06.        Compensation
and Indemnity. The Issuer, or, upon the failure of the Issuer to pay, each Guarantor (if any), jointly and severally (subject to
the conditions set forth in Article 11), shall pay to the Trustee from time to time compensation for its services as agreed to in
writing. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Issuer
shall reimburse the Trustee upon request for all reasonable out-of-pocket expenses Incurred or made by it, including costs of collection,
in addition to the compensation for its services. Such expenses shall include the reasonable compensation and expenses, disbursements
and advances of the Trustee’s agents, counsel, accountants and experts. The Issuer and each Guarantor, jointly and severally shall
indemnify the Trustee against any and all loss, liability, claim, damage or expense (including reasonable attorneys’ fees and expenses)
Incurred by or in connection with the acceptance or administration of this Indenture and the other Notes Documents and the performance
of its duties hereunder and thereunder, including the costs and expenses of enforcing this Indenture or Guarantee against the Issuer
or a Guarantor (including this Section 7.06) and defending itself against or investigating any claim (whether asserted by the Issuer,
any Guarantor, any Holder or any other Person). The Trustee shall notify the Issuer of any claim for which it may seek indemnity promptly
upon obtaining actual knowledge thereof; provided, however, that any failure so to notify the Issuer shall not relieve
the Issuer or any Guarantor of its indemnity obligations hereunder. The Issuer shall defend the claim and the Trustee shall provide reasonable
cooperation at the Issuer’s expense in the defense. The Trustee may have separate counsel and the Issuer and the Guarantors, as
applicable, shall pay the reasonable fees and expenses of such counsel; provided, however, that the Issuer shall not be
required to pay such fees and expenses if it assumes the Trustee’s defense and, in the Trustee’s reasonable judgment, there
is no conflict of interest between the Issuer or the Guarantors, as applicable, and the Trustee in connection with such defense. The
Issuer need not reimburse any expense or indemnify against any loss, liability or expense Incurred by an indemnified party through such
party’s own willful misconduct, gross negligence or fraud as determined by a final order of a court of competent jurisdiction.

 

To secure the Issuer’s and the Guarantors’
payment obligations in this Section 7.06, the Trustee shall have a Lien prior to the Securities on all money or property held or
collected by the Trustee other than money or property held in trust to pay principal of and interest on particular Securities.

 

The Issuer’s and the Guarantors’ payment
obligations pursuant to this Section 7.06 shall survive the satisfaction or discharge of this Indenture, any rejection or termination
of this Indenture under any Bankruptcy Law or the resignation or removal of the Trustee. Without prejudice to any other rights available
to the Trustee under applicable law, when the Trustee incurs expenses after the occurrence of a Default specified in Section 6.01(e) or
(f) with respect to the Issuer, the expenses are intended to constitute expenses of administration under the Bankruptcy Law.

 

    
-107-

     

    

For the avoidance of doubt, the rights, privileges,
protections, immunities and benefits given to the Trustee in this Section 7.06, including its right to be indemnified, are extended
to, and shall be enforceable by, the Trustee in each of its capacities hereunder, and by each agent, custodian and other Person employed
to act hereunder.

 

SECTION 7.07.       Replacement
of Trustee.

 

(a)           The
Trustee may resign at any time by so notifying the Issuer. The Holders of a majority in principal amount of the Securities may remove
the Trustee by so notifying the Trustee and may appoint a successor Trustee. The Issuer may remove the Trustee if:

 

(i)            the
Trustee fails to comply with Section 7.09;

 

(ii)           the
Trustee is adjudged bankrupt or insolvent;

 

(iii)          a
receiver or other public officer takes charge of the Trustee or its property; or

 

(iv)          the
Trustee otherwise becomes incapable of acting.

 

(b)           If
the Trustee resigns, is removed by the Issuer or by the Holders of a majority in principal amount of the Securities and such Holders
do not reasonably promptly appoint a successor Trustee, or if a vacancy exists in the office of Trustee for any reason (the Trustee in
such event being referred to herein as the retiring Trustee), the Issuer shall appoint a successor Trustee within 30 days of receiving
notice of the resignation or removal of the Trustee.

 

(c)            A
successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Issuer. Thereupon the resignation
or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of
the Trustee under this Indenture. The successor Trustee shall mail a notice of its succession to the Holders. The retiring Trustee shall
promptly transfer all property held by it as Trustee to the successor Trustee (provided all sums owing to the Trustee hereunder are paid),
subject to the Lien provided for in Section 7.06.

 

(d)            If
a successor Trustee does not take office within 60 days after the retiring Trustee resigns or is removed, the retiring Trustee or the
Holders of 10% in principal amount of the Securities may petition at the expense of the Issuer any court of competent jurisdiction for
the appointment of a successor Trustee.

 

(e)            If
the Trustee fails to comply with Section 7.09, any Holder may petition any court of competent jurisdiction for the removal of the
Trustee and the appointment of a successor Trustee.

 

(f)            Notwithstanding
the replacement of the Trustee pursuant to this Section 7.07, the Issuer’s obligations under Section 7.06 shall continue
for the benefit of the retiring Trustee. In no event shall the retiring Trustee be held responsible for the actions or inactions of the
successor trustee.

 

SECTION 7.08.       Successor
Trustee by Merger. If the Trustee consolidates with, merges or converts into, or transfers all or substantially all its corporate
trust business or assets to, another corporation or banking association, the resulting, surviving or transferee corporation without any
further act shall be the successor Trustee.

 

    
-108-

     

    

 

In case at the time such successor or successors
by merger, conversion or consolidation to the Trustee shall succeed to the trusts created by this Indenture any of the Securities shall
have been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor
trustee, and deliver such Securities so authenticated; and in case at that time any of the Securities shall not have been authenticated,
any successor to the Trustee may authenticate such Securities either in the name of any predecessor hereunder or in the name of the successor
to the Trustee; and in all such cases such certificates shall have the full force which it is anywhere in the Securities or in this Indenture
provided that the certificate of the Trustee shall have.

 

SECTION 7.09.        Eligibility;
Disqualification. There shall at all times be a Trustee hereunder that is a corporation organized and doing business under the laws
of the United States of America or of any state thereof that is authorized under such laws to exercise corporate trustee power, that
is subject to supervision or examination by federal or state authorities and that has combined capital and surplus of at least $50,000,000
as set forth in its most recent published annual report of condition.

 

SECTION 7.10.       Resignation
of Agents.(a)     Any Agent may resign its appointment hereunder at any time without the need to give
any reason and without being responsible for any costs associated therewith by giving notice to the Issuer and the Trustee (and in the
case of resignation of the Paying Agent, the Paying Agent giving 30 days’ written notice) (waivable by the Issuer and the Trustee);
provided that in the case of resignation of the Paying Agent no such resignation shall take effect until a new Paying Agent shall
have been appointed by the Issuer to exercise the powers and undertake the duties hereby conferred and imposed upon the Paying Agent;
provided, further, that the Trustee may resign as Paying Agent or Registrar only if the Trustee also resigns as Trustee in accordance
with Section 7.07. Following receipt of a notice of resignation from any Agent, the Issuer shall promptly give notice thereof to
the Holders in accordance with Section 12.02.

 

(b)           If
any Agent gives notice of its resignation in accordance with this Section 7.10 and a replacement Agent is required and by the tenth
day before the expiration of such notice such replacement has not been duly appointed, such Agent may itself appoint as its replacement
any reputable and experienced financial institution or may petition a court of competent jurisdiction, with reasonable costs and expenses
by the Agent in relation to such petition to be paid by the Issuer. Immediately following such appointment, the Issuer shall give notice
of such appointment to the Trustee, the remaining Agents and the Holders whereupon the Issuer, the Trustee, the remaining Agents and
the replacement Agent shall acquire and become subject to the same rights and obligations between themselves as if they had entered into
an agreement in the form mutatis mutandis of this Indenture.

 

Upon its resignation becoming effective the Paying
Agent shall forthwith transfer all moneys held by it hereunder, if any, to the successor Paying Agent or, if none, the Trustee or to
the Trustee’s order, but shall have no other duties or responsibilities hereunder, and shall be entitled to the payment by the
Issuer of its remuneration for the services previously rendered hereunder and to the reimbursement of all reasonable expenses (including
legal fees) incurred in connection therewith.

ARTICLE 8

 

DISCHARGE OF INDENTURE; DEFEASANCE

 

SECTION 8.01.        Discharge
of Liability on Securities; Defeasance. This Indenture shall be discharged and shall cease to be of further effect as to all outstanding
Securities (except for certain rights of the Trustee and the Issuer’s obligations with respect thereto), and the Guarantors will
be released without any further action by Holders, when:

 

(a)           either
(i) all the Securities theretofore authenticated and delivered (other than Securities pursuant to Section 2.08 which have been
replaced or paid and Securities for whose payment money has theretofore been deposited in trust) have been delivered to the Trustee for
cancellation or (ii) all of the Securities (a) have become due and payable, (b) will become due and payable within one
year or (c) have been or 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 or any Guarantor has irrevocably
deposited or caused to be deposited with the Trustee (or an entity designated or appointed (as agent) by it for this purpose) money or
U.S. Government Obligations sufficient, in an opinion of an Independent Financial Advisor, which shall be delivered to the Trustee, to
pay and discharge the entire Indebtedness on the Securities not theretofore delivered to the Trustee for cancellation, for principal
of, premium, if any, and interest on such Securities to the date of maturity or redemption together with irrevocable instructions from
the Issuer directing the Trustee to apply or cause to be applied such funds to the payment thereof at maturity or redemption, as the
case may be;

 

(b)           the
Issuer and/or the Guarantors have paid all other sums payable under this Indenture; and

 

(c)           the
Issuer has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel (which may be subject to customary assumptions
and exclusions) each stating that all conditions precedent under this Indenture relating to the satisfaction and discharge of this Indenture
have been complied with;

 

provided that any such counsel may rely on such Officer’s
Certificate as to matters of fact (including as to compliance with the foregoing clauses (a) and (b)).

 

Subject to Sections 8.01(c) and 8.02,
the Issuer at any time may cure all then existing Events of Default and terminate (i) all of its obligations and all obligations
of the Guarantors under the Securities and this Indenture (“legal defeasance option”) or (ii) its obligations
under Article 4 (other than Sections 4.01 and 4.12) and the operation of Section 5.01 and Sections 6.01(c) (with
respect to any Default under Article 4 (other than Sections 4.01 and 4.12)), 6.01(d), 6.01(e) (only with respect to Significant
Subsidiaries of UK Holdco (other than the Issuer)), 6.01(f) (only with respect to Significant Subsidiaries of UK Holdco (other than
the Issuer)), 6.01(g) or 6.01(h) (“covenant defeasance option”). The Issuer may exercise its legal defeasance
option notwithstanding its prior exercise of its covenant defeasance option. In the event that the Issuer terminates all of its obligations
under the Securities and this Indenture (with respect to such Securities) by exercising its legal defeasance option or its covenant defeasance
option, the obligations of each Guarantor under its Guarantee of such Securities shall be terminated simultaneously with the termination
of such obligations.

 

If the Issuer exercises its legal defeasance option,
payment of the Securities so defeased may not be accelerated because of an Event of Default. If the Issuer exercises its covenant defeasance
option, payment of the Securities so defeased may not be accelerated because of an Event of Default specified in Section 6.01(c) (with
respect to any Default by UK Holdco or any of its Restricted Subsidiaries with any of its obligations under Article 4 other than
Sections 4.01 and 4.12), 6.01(d), 6.01(e) (only with respect to Significant Subsidiaries of UK Holdco (other than the Issuer)),
6.01(f) (only with respect to Significant Subsidiaries of UK Holdco (other than the Issuer)), 6.01(g) or 6.01(h).

 

    
-110-

     

    

 

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 has terminated.

 

(d)            Notwithstanding
clause (a) above, the Issuer’s obligations in Sections 2.04, 2.05, 2.06, 2.07, 2.08, 2.09, 7.06, 7.07 and in this Article 8
shall survive until the Securities have been paid in full. Thereafter, the Issuer’s obligations in Sections 7.06, 8.05 and 8.06
shall survive such satisfaction and discharge.

 

SECTION 8.02.       Conditions
to Defeasance.

 

(a)          The
Issuer may exercise its legal defeasance option or its covenant defeasance option only if:

 

(i)            the
Issuer irrevocably deposits in trust with the Trustee (or an entity designated or appointed (as agent) by it for this purpose) cash in
U.S. Dollars or U.S. Government Obligations or a combination thereof sufficient (in the opinion of an Independent Financial Advisor,
which shall be delivered to the Trustee), for the payment of principal, premium (if any) and interest on the Securities to redemption
or maturity, as the case may be;

 

(ii)           the
Issuer delivers to the Trustee an Officer’s Certificate stating that the deposit was not made with the intent of defeating, hindering,
delaying or defrauding any creditors of the Issuer or any Guarantors or others;

 

(iii)          the
deposit does not constitute a default under any other material agreement or contract relating to Indebtedness binding on the Issuer (other
than a default resulting from borrowing funds to be applied to make the deposit required to effect such legal defeasance or covenant
defeasance and any similar and simultaneous deposit relating to such other Indebtedness and, in each case, the granting of Liens in connection
therewith);

 

(iv)          in
the case of the legal defeasance option, the Issuer shall have delivered to the Trustee an Opinion of Counsel (which Opinion of Counsel
may be subject to customary assumptions and exclusions) to the effect that the beneficial owners of the Securities will not recognize
income, gain or loss for U.S. federal income tax purposes as a result of such deposit and defeasance and will be subject to U.S. federal
income tax on the same amounts, in the same manner and at the same times as would have been the case if such deposit and defeasance had
not occurred, provided that such Opinion of Counsel must be based on a ruling received from, or published by, the Internal Revenue
Service or a change in applicable U.S. federal income tax law since the date of this Indenture;

 

(v)           in
the case of the covenant defeasance option, the Issuer shall have delivered to the Trustee an Opinion of Counsel (which Opinion of Counsel
may be subject to customary assumptions and exclusions) to the effect that the beneficial owners of the Securities will not recognize
income, gain or loss for U.S. federal income tax purposes as a result of such deposit and defeasance and will be subject to U.S. federal
income tax on the same amounts, in the same manner and at the same times as would have been the case if such deposit and defeasance had
not occurred; and

 

(vi)          the
Issuer delivers to the Trustee an Officer’s Certificate and an Opinion of Counsel (which Opinion of Counsel may be subject to customary
assumptions and exclusions), each stating that all conditions precedent to the defeasance and discharge of the Securities to be so defeased
and discharged as contemplated by this Article 8 have been complied with.

 

    
-111-

     

    

 

Notwithstanding the foregoing, the Opinion of Counsel
required by Section 8.02(a)(iv) above need not be delivered if all Securities not theretofore delivered to the Trustee for
cancellation (x) are due and payable within one year or (y) have been or will become due and payable 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.

 

(b)            Before
or after a deposit, the Issuer may make arrangements satisfactory to the Trustee for the redemption of such Securities at a future date
in accordance with Article 3.

 

SECTION 8.03.        Application
of Trust Money. The Trustee shall hold in trust money or U.S. Government Obligations (including proceeds thereof) deposited with
it pursuant to this Article 8. It shall apply the deposited money and the money from U.S. Government Obligations through each Paying
Agent and in accordance with this Indenture to the payment of principal of and interest on the Securities so discharged or defeased.

 

SECTION 8.04.        Repayment
to Issuer. Each of the Trustee and each Paying Agent shall promptly turn over to the Issuer upon request any money or U.S. Government
Obligations held by it as provided in this Article 8 which, in the written opinion of an Independent Financial Advisor delivered
to the Trustee (which delivery shall only be required if U.S. Government Obligations have been so deposited), are in excess of the amount
thereof which would then be required to be deposited to effect an equivalent discharge or defeasance in accordance with this Article 8.

 

Subject to any applicable abandoned property law,
the Trustee and the 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 the Paying Agent shall have no further liability with respect to such monies.

 

SECTION 8.05.        Indemnity
for U.S. Government Obligations. The Issuer shall pay and shall indemnify the Trustee against any tax, fee or other charge imposed
on or assessed against deposited U.S. Government Obligations or the principal and interest received on such U.S. Government Obligations.

 

SECTION 8.06.        Reinstatement.
If the Trustee or any Paying Agent is unable to apply any money or U.S. Government Obligations in accordance with this Article 8
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 this Indenture and the Securities so discharged or defeased
shall be revived and reinstated as though no deposit had occurred pursuant to this Article 8 until such time as the Trustee or any
Paying Agent is permitted to apply all such money or U.S. Government Obligations in accordance with this Article 8; provided,
however, that, if the Issuer has made any payment of principal of or interest on, any such Securities because of the reinstatement
of its obligations, the Issuer shall be subrogated to the rights of the Holders of such Securities to receive such payment from the money
or U.S. Government Obligations held by the Trustee or any Paying Agent.

such amendment, supplement or waiver, and upon receipt by the Trustee of the documents described in Section 9.06, the Trustee shall
join with the Issuer in the execution of such supplemental indenture.

 

SECTION 9.02.       With
Consent of the Holders. Except as otherwise provided in Section 9.01 or this Section 9.02, the Issuer and the Trustee may
amend this Indenture, the Securities or the Guarantees, with the consent of the Holders of at least a majority in aggregate principal
amount of the Securities then outstanding voting as a single class (including, without limitation, consents obtained in connection with
a purchase of, or tender offer or exchange offer for the Securities) and any existing or past default or compliance with any provisions
of such documents may be waived with the consent of the Holders of a majority in principal amount of the Securities then outstanding
(including, without limitation, consents obtained in connection with the purchase of, or tender offer or exchange offer for, Securities).
However, without the consent of each Holder of an outstanding Security affected, no amendment may (with respect to any Securities held
by a non-consenting Holder):

 

(a)            reduce
the percentage of the aggregate principal amount of Securities whose Holders must consent to an amendment, supplement or waiver;

(e)            make
any Security payable in money other than that stated in such Security;

 

    
-114-

     

    

 

(f)            impair
the right of any Holder to receive payment of principal of, premium, if any, and interest on such Holder’s Securities on or after
the due dates therefor or to institute suit for the enforcement of any payment on or with respect to such Holder’s Securities;

 

(g)           make
any change in Section 6.04 or 6.07 or the second sentence of this Section 9.02;

 

(h)           expressly

It shall not be necessary for the consent of the
Holders under this Section 9.02 to approve the particular form of any proposed amendment, waiver or consent, but it shall be sufficient
if such consent approves the substance thereof. For the avoidance of doubt, no amendment to, or deletion of any of the covenants described
under Article 4 or Section 5.01, shall be deemed to impair or affect any rights of Holders to receive payment of principal
of, or premium, if any, or interest on, the Securities.

 

Upon the request of the Issuer accompanied by a
resolution of the Board of Directors of the Issuer authorizing the execution of any supplemental indenture entered into to effect any
such amendment, supplement or waiver, and upon receipt by the Trustee of the documents described in Section 9.06, the Trustee, subject
to its rights in Section 9.06, shall join with the Issuer in the execution of such supplemental indenture.

 

SECTION 9.03.        [Reserved].

 

SECTION 9.04.        Revocation
and Effect of Consents and Waivers.

 

(a)          A
consent to an amendment or a waiver by a Holder of a Security shall bind the Holder and every subsequent Holder of that Security or portion
of the Security that evidences the same debt as the consenting Holder’s Security, even if notation of the consent or waiver is
not made on the Security. However, any such Holder or subsequent Holder may revoke the consent or waiver as to such Holder’s Security
or portion of the Security if the Trustee receives the notice of revocation before the date on which the consent or waiver becomes effective.
After an amendment or waiver becomes effective, it shall bind every Holder. An amendment or waiver becomes effective upon the (i) receipt
by the Issuer or the Trustee of consents by the Holders of the requisite principal amount of Securities, (ii) satisfaction of conditions
to effectiveness as set forth in this Indenture and any supplemental indenture hereto containing such amendment or waiver and (iii) execution
of such amendment or waiver (or supplemental indenture) by the Issuer and the Trustee.

 

(b)          The
Issuer may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to give their consent
or take any other action described above or required or permitted to be taken pursuant to this Indenture. If a record date is fixed,
then notwithstanding Section 9.04(a), those Persons who were Holders at such record date (or their duly designated proxies), and
only those Persons, shall be entitled to give such consent or to revoke any consent previously given or to take any such action, whether
or not such Persons continue to be Holders after such record date. No such consent shall be valid or effective for more than 120 days
after such record date.

 

SECTION 9.05.       Notation
on or Exchange of Securities. If an amendment, supplement or waiver changes the terms of a Security, the Issuer may require the Holder
of the Security to deliver it to the Trustee. The Trustee may place an appropriate notation on the Security regarding the changed terms
and return it to the Holder. Alternatively, if the Issuer so determines, the Issuer in exchange for the Security shall issue and upon
receipt of an Authentication Order the Trustee (or its Authenticating Agent) shall authenticate a new Security that reflects the changed
terms. Failure to make the appropriate notation or to issue a new Security shall not affect the validity of such amendment, supplement
or waiver.

 

    
-115-

     

    

 

SECTION 9.06.        Trustee
to Sign Amendments. The Trustee shall sign any amendment, supplement or waiver (including any amended or supplemental indenture,
security documents or intercreditor agreements) authorized pursuant to this Article 9 if the amendment or supplement does not adversely
affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may but need not sign it. In signing such
amendment, the Trustee shall be entitled to receive indemnity satisfactory to it and shall be provided with, and (subject to Section 7.01)
shall be fully protected in relying upon, an Officer’s Certificate and Opinion of Counsel stating that such amendment, supplement
or waiver is authorized or permitted by this Indenture.

 

SECTION 9.07.       Additional
Voting Terms. All Securities issued under this Indenture shall vote and consent together on all matters (as to which any of such
Securities may vote) as one class and no series of Securities will have the right to vote or consent as a separate class on any matter.

GUARANTEES

 

SECTION 11.01.      Guarantees.

 

(a)            Prior
to the Escrow Release Date, the Securities will not be guaranteed.

 

(b)           On
the Completion Date, and subject to the Guaranty Principles, Holdings, UK Holdco and each of UK Holdco’s Restricted Subsidiaries,
in each case, that is an obligor under the Credit Agreement immediately prior to such date, will jointly and severally, irrevocably and
unconditionally, guarantee on a senior unsecured basis, the performance and punctual payment when due, whether at Stated Maturity, by
acceleration or otherwise, of all obligations of the Issuer under this Indenture and the Securities, whether for payment of principal
of, premium, if any, or interest on the Securities, fees, expenses, indemnification or otherwise (all such obligations guaranteed by
such Guarantors being herein called the “Guaranteed Obligations”). Each Guarantor further agrees that the Guaranteed
Obligations may be extended or renewed, in whole or in part, without notice or further assent from each such Guarantor, and that each
such Guarantor shall remain bound under this Article 11 notwithstanding any extension or renewal of any Guaranteed Obligation.

 

(c)            Each
Guarantor waives presentation to, demand of payment from and protest to the Issuer of any of the Guaranteed Obligations and also waives
notice of protest for nonpayment. Each Guarantor waives notice of any default under the Securities or the Guaranteed Obligations. The
obligations of each Guarantor hereunder shall not be affected by (i) the failure of any Holder or the Trustee to assert any claim
or demand or to enforce any right or remedy against the Issuer or any other Person under this Indenture, the Securities or any other
agreement or otherwise; (ii) any extension or renewal of this Indenture, the Securities or any other agreement; (iii) any rescission,
waiver, amendment or modification of any of the terms or provisions of this Indenture, the Securities or any other agreement; (iv) the
release of any security, if any, held by any Holder or the Trustee for the Guaranteed Obligations or any Guarantor; (v) the failure
of any Holder or Trustee to exercise any right or remedy against any Other Guarantor (as defined below) of the Guaranteed Obligations;
or (vi) any change in the ownership of such Guarantor, except as provided in Section 11.02(d).

 

    
-116-

     

    

 

 

(d)            Except
as otherwise provided herein, each Guarantor hereby waives any right to which it may be entitled to have its obligations hereunder divided
among the Guarantors, such that such Guarantor’s obligations would be less than the full amount claimed. Each Guarantor hereby waives
any right to which it may be entitled to have the assets of the Issuer first be used and depleted as payment of the Issuer’s or
such Guarantor’s obligations hereunder prior to any amounts being claimed from or paid by such Guarantor hereunder. Each Guarantor
hereby waives any right to which it may be entitled to require that the Issuer be sued prior to an action being initiated against such
Guarantor.

 

(e)            Each
Guarantor further agrees that its Guarantee herein constitutes a guarantee of payment, performance and compliance when due (and not a
guarantee of collection) and waives any right to require that any resort be had by any Holder or Trustee to any security held for payment
of the Guaranteed Obligations.

 

(f)            Except
as expressly set forth in Sections 8.01 and 11.02, the obligations of each Guarantor hereunder shall not be subject to any reduction,
limitation, impairment or termination for any reason, including any claim of waiver, release, surrender, alteration or compromise, and
shall not be subject to any defense of setoff, counterclaim, recoupment or termination whatsoever or by reason of the invalidity, illegality
or unenforceability of the Guaranteed Obligations or otherwise. Without limiting the generality of the foregoing, the obligations of each
Guarantor herein shall not be discharged or impaired or otherwise affected by the failure of any Holder or the Trustee to assert any claim
or demand or to enforce any remedy under this Indenture, the Securities or any other agreement, by any waiver or modification of any thereof,
by any default, failure or delay, willful or otherwise, in the performance of the obligations, or by any other act or thing or omission
or delay to do any other act or thing which may or might in any manner or to any extent vary the risk of any Guarantor or would otherwise
operate as a discharge of any Guarantor as a matter of law or equity.

 

(g)            Except
as set forth in Sections 8.01 and 11.02, each Guarantor agrees that its Guarantee shall remain in full force and effect until payment
in full of all the Guaranteed Obligations. Except as set forth in Sections 8.01 and 11.02, each Guarantor further agrees that its Guarantee
herein shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of principal
of or interest on any Guaranteed Obligation is rescinded or must otherwise be restored by any Holder or the Trustee upon the bankruptcy
or reorganization of the Issuer or otherwise.

 

(h)            In
furtherance of the foregoing and not in limitation of any other right which any Holder or the Trustee has at law or in equity against
any Guarantor by virtue hereof, upon the failure of the Issuer to pay the principal of or interest on any Guaranteed Obligation when and
as the same shall become due, whether at maturity, by acceleration, by redemption or otherwise, or to perform or comply with any other
Guaranteed Obligation, each Guarantor hereby promises to and shall, upon receipt of written demand by the Trustee, forthwith pay, or cause
to be paid, in cash, to the Trustee an amount equal to the sum of (i) the unpaid principal amount of such Guaranteed Obligations,
(ii) accrued and unpaid interest on such Guaranteed Obligations (but only to the extent not prohibited by applicable law) and (iii) all
other monetary obligations of the Issuer to the Holders and the Trustee in respect of the Guaranteed Obligations.

(i)             Each
Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Holders in respect of any Guaranteed Obligations
guaranteed hereby until payment in full of all Guaranteed Obligations. Each Guarantor further agrees that, as between it, on the one hand,
and the Holders and the Trustee, on the other hand, (i) the maturity of the Guaranteed Obligations guaranteed hereby may be accelerated
as provided in Article 6 for the purposes of any Guarantee herein, notwithstanding any stay, injunction or other prohibition preventing
such acceleration in respect of the Guaranteed Obligations guaranteed hereby, and (ii) in the event of any declaration of acceleration
of such Guaranteed Obligations as provided in Article 6, such Guaranteed Obligations (whether or not due and payable) shall forthwith
become due and payable by such Guarantor for the purposes of this Section 11.01.

 

(j)            Each
Guarantor also agrees to pay any and all costs and expenses (including reasonable attorneys’ fees and expenses) incurred by any
Holder or the Trustee in enforcing any rights under this Section 11.01.

 

(k)           Upon
request of the Trustee, each Guarantor shall execute and deliver such further instruments and do such further acts as may be reasonably
necessary or proper to carry out more effectively the purpose of this Indenture.

 

(l)            Any
Guarantee given by any direct or indirect parent of Holdings may be released and discharged from all obligations under this Article 11
at any time upon written notice to the Trustee from such direct or indirect parent of UK Holdco.

 

SECTION 11.02.            Limitation
on Guarantor Liability.

 

(a)           Any
term or provision of this Indenture to the contrary notwithstanding, the maximum aggregate amount of the Guaranteed Obligations guaranteed
hereunder by any Guarantor shall not exceed the maximum amount that can be hereby guaranteed by the applicable Guarantor without rendering

furtherance of the foregoing and to the extent applicable, a Guarantor’s liability in respect of its Guarantee shall be limited
to the extent set forth below:

anything to the contrary contained in this Indenture or the Securities, the aggregate obligations of any Guarantor whose registered office/place
of central administration is in Luxembourg (a “Luxembourg Guarantor”) in respect of the Issuer or any Restricted Subsidiary
which is not a direct or indirect subsidiary of such Luxembourg Guarantor shall be limited at any time to an aggregate amount not exceeding
90% of the greater of:

 

(A)            an
amount equal to the sum of the Luxembourg Guarantor’s net assets (Capitaux Propres, as referred to in annex I to the grand-ducal

financial information of the Luxembourg Guarantor as at the date of this Indenture or (as applicable) as at the date of its accession
as a Guarantor, including, without limitation, its most recently and duly approved financial statements (comptes annuels) and any
(unaudited) interim financial statements signed by its board of managers (gérants) or directors (administrateurs),
as applicable; and

 

    	 	-118-	 

     

    

 

(B)            an
amount equal to the sum of the Luxembourg Guarantor’s net assets (Capitaux Propres), as referred to in the Regulation and
its subordinated debt (dettes subordonnées), as reflected in the financial information of the Luxembourg Guarantor as at
the date the Guarantee is called, including, without limitation, its most recently and duly approved financial statements (comptes
annuels) and any (unaudited) interim financial statements signed by its board of managers (gérants).

 

(2)            The
limitation set forth at paragraph (1) above shall not apply to any amounts received under the Securities and made available, in any
form whatsoever, to such Luxembourg Guarantor or any of its direct or indirect subsidiaries.

 

(3)            Any
Guarantee by any Luxembourg Guarantor under this Section 11.02 will not extend to include any obligations or liabilities if such
inclusion would constitute a breach of the financial assistance prohibitions contained at Article 430-19 (where applicable) of the
Luxembourg act on commercial companies of 10 August 1915, as amended.

 

(ii)            Limitations
in Japan. Notwithstanding anything to the contrary contained in this Indenture, any Guarantee by any Guarantor which is incorporated
under the laws of Japan shall not be effective to the extent that it would result in violating Article 135 and 155 through 165 or
any other provisions of the Companies Act of Japan (Law No. 86 of 2005), as amended.

 

(iii)            Limitations
in the United Kingdom. Notwithstanding anything to the contrary contained in this Indenture or the Securities, this Guarantee does
not apply to any liability to the extent that it would result in such Guarantee constituting unlawful financial assistance within the
meaning of sections 678 or 679 of the United Kingdom Companies Act 2006, as amended.

 

(iv)            Limitations
Applicable to Certain Other Guarantors. Each Guarantor that as of the date of this Indenture or thereafter is incorporated, organized
or formed, as the case may be, under the laws of any jurisdiction other than those jurisdictions set forth in clauses (i) through
(iii) above (an “Other Guarantor”), and by its acceptance hereof, each Holder and the Trustee, hereby confirm
that it is the intention of all such parties that the Guarantee of an Other Guarantor does not constitute a fraudulent transfer or conveyance
for purposes of, or otherwise violate, applicable law. To effectuate the foregoing intention, each Holder and each Other Guarantor hereby
irrevocably agrees that the obligations of an Other Guarantor under its Guarantee shall be limited to the maximum amount as will, after
giving effect to all other contingent and fixed liabilities of such Other Guarantor result in the obligations of such Other Guarantor
not constituting such a fraudulent transfer or conveyance or otherwise violating applicable law and be subject to such other limitations
under applicable law as are described in the supplemental indenture.

 

(c)            Notwithstanding
anything in this Section 11.02 to the contrary, if following the date of this Indenture:

 

(i)            there
shall be any change in the laws of any of the jurisdictions set forth in clauses (i) through (iv) of Section 11.02(b);

 

    	 	-119-	 

     

    

 

(ii)           there
shall be any change in the laws under which any Other Guarantor is incorporated, organized or formed, as the case may be; or

 

(iii)          any
Person shall be required to execute a Guarantee pursuant to Section 4.10 or Section 11.01 otherwise hereunder and such Person
is incorporated, organized or formed, as the case may be, under the laws of any jurisdiction other than those in which entities are contemplated
to become Guarantors as of the date hereof, including those jurisdictions addressed in clauses (i) and (ii) of Section 11.02
and other than any jurisdiction in which a then existing Other Guarantor is incorporated, organized or formed, as the case may be, and
the Issuer shall reasonably determine that the provisions of Section 11.02(b)(iii) hereof with respect to any Other Guarantor
shall not adequately address the limitations on such Guarantee imposed by applicable law of the jurisdiction of incorporation, organization
or formation, as the case may be, of such Person;

 

(iv)          then
upon the delivery of an Officer’s Certificate, the Issuer shall be entitled to amend such clause or add such additional provisions
to such clause, as the case may be, to the extent necessary so that the Guarantee of a Guarantor does not violate applicable law.

 

(d)            A
Guarantee as to any Guarantor shall automatically terminate and be of no further force or effect and such Guarantor shall be deemed to
be unconditionally released and discharged from all obligations under this Article 11 upon the earliest to occur of:

 

(i)            except
in the case of Holdings or UK Holdco, the sale, disposition or other transfer (including through merger, dissolution or consolidation)
of the Capital Stock of such Guarantor to a Person other than Holdings, UK Holdco or a Restricted Subsidiary if after such sale, disposition
or other transfer, such Guarantor is no longer a Restricted Subsidiary, or the sale, disposition or other transfer of all or substantially
all the assets of such Guarantor, in each case, if such sale, disposition or other transfer is made in compliance with this Indenture,

Issuer designating such Guarantor as, or such Guarantor becoming (in each case other than Holdings or UK Holdco), (i) an Unrestricted
Subsidiary in accordance with the provisions set forth under Section 4.04 and the definition of “Unrestricted Subsidiary”
or (ii) an Excluded Subsidiary in accordance with the definition of “Excluded Subsidiary” (unless such subsidiary continues
to provide a guarantee under the Credit Agreement),

 

(iii)          in
the case of any Restricted Subsidiary that is required to guarantee the Securities pursuant to Section 4.10, the release or discharge
of the obligation by such Restricted Subsidiary of Indebtedness of UK Holdco or any Restricted Subsidiary or the repayment of the Indebtedness
or Disqualified Stock, in each case, which resulted in the obligation to guarantee the Securities, except if a release or discharge is
by or as a result of payment in connection with the enforcement of remedies under such other obligation and a Default or Event of Default
would occur thereby,

 

(iv)          the
Issuer’s exercise of its legal defeasance option or covenant defeasance option as described under Section 8.01 or if the Issuer’s
obligations under this Indenture are discharged in accordance with the terms of this Indenture,

 

(v)           the
merger or consolidation of such Guarantor with and into the Issuer or another Guarantor that is the surviving Person in such merger or
consolidation, or upon the liquidation or dissolution of such Guarantor following the transfer of all or substantially all of its assets
to the Issuer or another Guarantor,

 

    	 	-120-	 

     

    

 

(vi)          in
accordance with Article 9, or

 

(vii)         except
in the case of Holdings or UK Holdco, upon the release or discharge of all other Guarantees by such Guarantor of Indebtedness of the Issuer
or any other Guarantor, other than in the case of repayment in full of such Indebtedness.

 

SECTION 11.03.            No
Waiver. Neither a failure nor a delay on the part of either the Trustee or the Holders in exercising any right, power or privilege
under this Article 11 shall operate as a waiver thereof, nor shall a single or partial exercise thereof preclude any other or further
exercise of any right, power or privilege. The rights, remedies and benefits of the Trustee and the Holders herein expressly specified
are cumulative and not exclusive of any other rights, remedies or benefits which either may have under this Article 11 at law, in
equity, by statute or otherwise.

 

SECTION 11.04.            Modification.
No modification, amendment or waiver of any provision of this Article 11, nor the consent to any departure by any Guarantor therefrom,
shall in any event be effective unless the same shall be in writing and signed by the Trustee, and then such waiver or consent shall be
effective only in the specific instance and for the purpose for which given. No notice to or demand on any Guarantor in any case shall
entitle such Guarantor to any other or further notice or demand in the same, similar or other circumstances.

 

SECTION 11.05.            Execution
of Supplemental Indenture for Future Guarantors. Each Subsidiary and other Person which is required or elects to become a Guarantor
pursuant to Section 4.10 shall promptly execute and deliver to the Trustee a supplemental indenture in the form of Exhibit C
hereto pursuant to which such Subsidiary or other Person shall become a Guarantor under this Article 11 and shall guarantee the Guaranteed
Obligations. Concurrently with the execution and delivery of such supplemental indenture, the Issuer shall deliver to the Trustee an Officer’s
Certificate stating that such supplemental indenture is authorized or permitted by this Indenture.

 

SECTION 11.06.            Non-Impairment.
The failure to endorse a Guarantee on any Security shall not affect or impair the validity thereof.

understanding of such instructions shall be deemed controlling. Subject to Section 7.02, the Trustee shall not be liable for any
losses, costs or expenses arising directly or indirectly from the Trustee’s reliance upon and compliance with such instructions
notwithstanding if such instructions conflict or are inconsistent with a subsequent written instruction. The party providing electronic
instructions agrees to assume all risk arising out of the use of such electronic methods to submit instructions and directions to the
Trustee, including without limitation the risk of the Trustee acting on unauthorized instructions, and the risk or interception and misuse
by third parties. Notwithstanding anything herein to the contrary, the Trustee is not under any obligation to agree to accept electronic
signatures in any form or in any format unless expressly agreed to by the Trustee pursuant to reasonable procedures approved by the Trustee.

Proceeding brought in any Specified Court. The parties irrevocably and unconditionally waive any objection to the laying of venue of any
Related Proceeding in the Specified Courts and irrevocably and unconditionally waive and agree not to plead or claim in any Specified
Court that any Related Proceeding brought in any Specified Court has been brought in an inconvenient forum. The Trustee reserves the right
to bring an action in any court that has jurisdiction over the trust estate, which may be a court other than the Specified Courts, when
seeking a direction from a court in the administration of the trust estate. On the Completion Date, each Guarantor that becomes party
to this Indenture via a supplemental indenture in the form of Exhibit C hereto that is organized outside the United States will appoint
(i) the Issuer or a Guarantor organized in the United States, any state thereof or the District of Columbia, which initially shall

of Immunity. With respect to any Related Proceeding, each party irrevocably waives, to the fullest extent permitted by applicable
law, all immunity (whether on the basis of sovereignty or otherwise) from jurisdiction, service of process, attachment (both before and
after judgment) and execution to which it might otherwise be entitled in the Specified Courts, and with respect to any suits, actions,
or proceedings instituted in regard to the enforcement of a judgment of any Specified Court in a Related Proceeding (a “Related
Judgment”), each party waives any such immunity in the Specified Courts or any other court of competent jurisdiction, and will
not raise or claim or cause to be pleaded any such immunity at or in respect of any such Related Proceeding or Related Judgment, including,
without limitation, any immunity pursuant to the United States Foreign Sovereign Immunities Act of 1976, as amended.

represent the same agreement. One signed copy is enough to prove this Indenture. The exchange of copies of this Indenture and of signature
pages by facsimile or PDF transmission shall constitute effective execution and delivery of this Indenture as to the parties hereto
and may be used in lieu of the original Indenture for all purposes. Signatures of the parties hereto transmitted by facsimile or PDF shall
be deemed to be their original signatures for all purposes.

 

SECTION 12.14.            Table

Capitalized terms used herein have the meanings assigned
to them in the Indenture referred to below unless otherwise indicated.

 

1.            Interest

 

CLARIVATE SCIENCE HOLDINGS CORPORATION, a Delaware
corporation (the “Issuer”), promises to pay interest on the principal amount of this Security at the rate per annum
shown above. The Issuer shall pay interest semiannually on June 30 and December 30 of each year, commencing December 30,
2021.1 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 or duly provided
for, from June 24, 2021 until the principal hereof is due. Interest shall be computed on the basis of a 360-day year of twelve 30-day
months. The Issuer shall pay interest on overdue principal at the rate borne by the Securities, 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 on the Securities (except
defaulted interest) to the Persons who are registered Holders at the close of business on the June 15 or December 15 next preceding
the interest payment date even if Securities are canceled after the record date and on or before the interest payment date (whether or
not a Business Day). The Holders must surrender Securities to a Paying Agent to collect principal payments. The Issuer shall pay principal,
premium, if any, and interest in U.S. Dollars. Payments in respect of the Securities represented by a Global Security (including principal
(upon presentation thereof to the Paying Agent), premium, if any, and interest) shall be made by wire transfer of immediately available
funds to the accounts specified by DTC or any successor depository. The Issuer will make all payments in respect of a certificated Security
(including principal, premium, if any, and interest), at the office of the 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; provided, however, that payments
on the Securities may also be made, in the case of a Holder of at least $1,000,000 aggregate principal amount of Securities, by wire transfer
to a U.S. Dollar account maintained by the payee with a bank in the United States if such Holder elects payment by wire transfer by giving
written notice to the Trustee or a Paying Agent to such effect designating such account no later than 30 days immediately preceding
the relevant due date for payment (or such other date as the Trustee may accept in its discretion).

 

3.            Paying
Agent and Registrar

 

Initially, Wilmington Trust, National Association
will act as the Paying Agent and Registrar. The Issuer may appoint and change any Paying Agent or Registrar without notice. The Issuer
or any domestically incorporated Wholly Owned Subsidiary of UK Holdco may act as Paying Agent or Registrar.

 

 

1With respect to Securities issued on the Issue Date.

 

    A-6 

     

    

 

4.            Indenture

 

The Issuer issued the Securities under an Indenture
dated as of June 24, 2021 (the “Indenture”), among the Issuer, the Guarantors from time to time party thereto
and the Trustee. Terms defined in the Indenture and not defined herein have the meanings ascribed thereto in the Indenture. The Securities
are subject to all terms and provisions of the Indenture, and the Holders are referred to the Indenture for a statement of such terms
and provisions. To the extent any provision of this Security conflicts with the express provisions of the Indenture, the provisions of
the Indenture shall govern and be controlling.

 

Prior to the Escrow Release Date, the Securities
will be senior secured obligations of the Issuer, secured by a first-priority security interest in the Escrow Account. Following the Completion
Date, the Securities will be senior unsecured obligations of the Issuer. [This Security is one of the Original Securities referred to
in the Indenture.] [This Security is an Additional Security referred to in the Indenture.]

 

Prior to the Escrow Release Date, the Securities
will not be guaranteed. To guarantee the due and punctual payment of the principal, premium, if any, and interest, on the Securities and
all other amounts payable by the Issuer under the Indenture and the Securities when and as the same shall be due and payable, whether
at maturity, by acceleration or otherwise, according to the terms of the Securities and the Indenture, on the Completion Date, the Guarantors
will, jointly and severally, irrevocably and unconditionally guarantee the Guaranteed Obligations on a senior unsecured basis pursuant
to the terms of the Indenture by executing a supplemental indenture in the form of Exhibit C to the Indenture, and to the extent
required by the Indenture.

 

5.            Optional
Redemption

 

Except as set forth in the following two paragraphs,
the Securities shall not be redeemable at the option of the Issuer prior to June 30, 2024. Thereafter, the Securities shall be redeemable
at the option of the Issuer, in whole at any time or in part from time to time, upon not less than 10 nor more than 60 days’
prior notice sent electronically or mailed by first-class mail to each Holder’s registered address or provided otherwise in accordance
with the procedures of DTC, at the following redemption prices (expressed as a percentage of principal amount), plus accrued and
unpaid interest, if any, to, but not including, the redemption date (subject to the right of the Holders of record on the relevant record
date to receive interest due on the relevant interest payment date), if redeemed during the 12-month period commencing on June 30
of the years set forth below:

 

	Period	Redemption Price
	2024	102.438%

In addition, at any time prior to June 30, 2024,
the Issuer may redeem the Securities at its option, in whole at any time or in part from time to time, upon not less than 10 nor more
than 60 days’ prior notice sent electronically or mailed by first-class mail to each Holder’s registered address or provided
otherwise in accordance with the procedures of DTC, at a redemption price equal to 100% of the principal amount of the Securities redeemed
plus the Applicable Premium, and accrued and unpaid interest, if any, to, but not including, the applicable redemption date (subject
to the right of the Holders of record on the relevant record date to receive interest due on the relevant interest payment date).

 

    A-7 

     

    

 

Notwithstanding the foregoing, at any time and from
time to time prior to June 30, 2024, the Issuer may redeem in the aggregate up to 40% of the aggregate principal amount of the Securities
issued (calculated after giving effect to any issuance of any Additional Securities) with funds in an aggregate amount not exceeding the
net cash proceeds of one or more Equity Offerings by UK Holdco or any direct or indirect parent of UK Holdco, in each case, to the extent
the net cash proceeds thereof are contributed to the common or preferred equity capital (other than Disqualified Stock) of the Issuer
or UK Holdco or used to purchase Capital Stock (other than Disqualified Stock) of the Issuer or UK Holdco from it, at a redemption price
(expressed as a percentage of the principal amount thereof) of 104.875% plus accrued and unpaid interest, if any, to, but not including,
the redemption date (subject to the right of the Holders of record on the relevant record date to receive interest due on the relevant
interest payment date); provided, however, that at least 50% of the original aggregate principal amount of the Securities
issued on the Issue Date remain outstanding after each such redemption, unless all such Securities are redeemed substantially concurrently;
and provided, further, that such redemption shall occur within 120 days after the date on which any such Equity Offering
is consummated upon not less than 10 nor more than 60 days’ notice provided to each Holder being redeemed and otherwise in accordance
with the procedures set forth in the Indenture.

 

In connection with any tender offer for the Securities,
including a Change of Control Offer or an Asset Sale Offer, if Holders of not less than 90% in aggregate principal amount of the outstanding
Securities validly tender and do not withdraw such Securities in such tender offer and the Issuer, or any third party making such tender
offer in lieu of the Issuer as described in the Indenture, purchases all of the Securities validly tendered and not withdrawn by such
Holders, the Issuer or such third party will have the right, upon not less than 10 days nor more than 60 days’ prior notice, provided
that such notice is given not more than 30 days following such purchase pursuant to such tender offer described in the Indenture), to
redeem all Securities that remain outstanding following such purchase at a redemption price in cash equal to the price offered to each
other Holder in such tender offer plus, to the extent not included in such tender offer payment, accrued and unpaid interest, if
any, to, but excluding, the redemption date.

 

In connection with any redemption of Securities (including
with funds in an aggregate amount not exceeding the net cash proceeds of an Equity Offering), any such redemption may, at the Issuer’s
discretion, be subject to one or more conditions precedent, including the completion of any related Equity Offering. In addition, if such
redemption or notice is subject to satisfaction of one or more conditions precedent, such notice shall state that, in the Issuer’s
discretion, the redemption date may be delayed until such time (including more than 60 days after the date the notice of redemption was
sent) as any or all such conditions shall be satisfied (or waived by the Issuer in its sole discretion), 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 so delayed. In addition, the Issuer may provide in such notice that payment of the redemption price and performance
of the Issuer’s obligations with respect to such redemption may be performed by another Person.

 

6.            Mandatory
Redemption; Special Mandatory Redemption

 

Except in the case of a Special Mandatory Redemption
(as further described in Section 3.12(c) of the Indenture), the Issuer shall not be required to redeem or make any sinking fund

2021, (ii) the Issuer shall have notified the Escrow Agent in writing that in its reasonable judgment, the ProQuest Acquisition will
not be consummated on or prior to such date or (iii) the ProQuest Agreement has been terminated, then the Issuer will redeem the
Securities on the terms set forth in Section 3.12(c) of the Indenture.

 

    A-8 

     

    

 

7.            Notice
of Redemption

which shall be subject to the terms of Section 3.12(c) of the Indenture, notice of redemption will be sent electronically or
mailed by first-class mail at least 10 days but not more than 60 days before the redemption date to each Holder of Securities
to be redeemed at his, her or its registered address or provided otherwise in accordance with the procedures of the Depository. Securities

sufficient to pay the redemption price of and accrued and unpaid interest on all Securities (or portions thereof) to be redeemed on the
redemption date is deposited with a Paying Agent on or before the redemption date and certain other conditions are satisfied, on and after
such redemption date, interest ceases to accrue on such Securities (or such portions thereof) called for redemption.

 

8.            Repurchase
of Securities at the Option of the Holders upon Change of Control and Asset Sales

 

Upon the occurrence of a Change of Control, each
Holder shall have the right, subject to certain conditions specified in the Indenture, to require the Issuer to repurchase all or any
part of such Holder’s Securities at a purchase price in cash equal to the Change of Control Payment, plus accrued and unpaid

offer or exchange offer for, such Securities) and (ii) any existing or past default or compliance with any provisions of such documents
may be waived with the consent of the Holders of a majority in principal amount of the Securities then outstanding (including, without
limitation, consents obtained in connection with a purchase of, or tender offer or exchange offer for, such Securities). Subject to certain
exceptions set forth in the Indenture, without the consent of any Holder, the Issuer and the Trustee may amend the Indenture, the Securities
or the Guarantees in the circumstances set forth in Section 9.01 of the Indenture.

 

14.            Defaults
and Remedies

 

If an Event of Default (other than an Event of Default
relating to certain events of bankruptcy, insolvency or reorganization of the Issuer) occurs and is continuing, the Trustee by written
notice to the Issuer or the Holders of at least 30% of the aggregate principal amount of outstanding Securities by written notice to the
Issuer and the Trustee, may declare the principal of, premium, if any, and accrued but unpaid interest, on all the Securities to be due
and payable. Upon such a declaration, such principal and interest, will be due and payable immediately. If an Event of Default relating
to certain events of bankruptcy, insolvency or reorganization of the Issuer occurs, the principal of, premium, if any, and interest on
the Securities shall ipso facto become and be immediately due and payable without any declaration or other act on the part of the Trustee
or any Holders. The Holders of a majority in principal amount of the outstanding Securities by notice to the Trustee may rescind an acceleration
and its consequences if the rescission would not conflict with any judgment or decree and if all existing Events of Default have been
cured or waived except nonpayment of principal or interest that has become due solely because of acceleration. No such rescission shall
affect any subsequent Default or impair any right consequent thereto.

 

If an Event of Default occurs and is continuing,
the Trustee shall be under no obligation to exercise any of the rights or powers under the Indenture at the request or direction of any
of the Holders unless such Holders have offered to the Trustee indemnity and/or security (which may include pre-funding) satisfactory
to it against all losses, liabilities and expenses which might be Incurred by it in compliance with such request or direction. Except
to enforce the right to receive payment of principal, premium (if any) or interest when due, no Holder may pursue any remedy with respect
to the Indenture or the Securities unless (i) the Holder gives to the Trustee written notice stating that an Event of Default is
continuing, (ii) the Holders of at least 30% of the aggregate principal amount of the Securities then outstanding make a written
request to the Trustee to pursue the remedy, (iii) such Holder or Holders offer to the Trustee security or indemnity (which may include
pre-funding) satisfactory to it against any loss, liability or expense, (iv) the Trustee does not comply with such request within
60 days after the receipt of the request and the offer of security or indemnity and (v) the Holders of a majority in principal
amount of outstanding Securities do not give the Trustee a direction inconsistent with the request within such 60-day period. Subject
to certain restrictions, the Holders of a majority in principal amount of the Securities then outstanding may direct the time, method
and place of conducting any proceeding for any remedy available to the Trustee or of exercising any trust or power conferred on the Trustee.
The Trustee, however, may refuse to follow any direction that conflicts with law or the Indenture or, subject to Section 7.01 of
the Indenture, that the Trustee determines is unduly prejudicial to the rights of any other Holder (it being understood that the Trustee
does not have an affirmative duty to ascertain whether or not any action or forbearance is unduly prejudicial to such Holders) or that
would involve the Trustee in personal liability, provided, however, that the Trustee may take any other action deemed proper
by the Trustee that is not inconsistent with such direction. Prior to taking any action under the Indenture, the Trustee shall be entitled
to indemnification and/or security (which may include pre-funding) satisfactory to it against all losses, liabilities and expenses caused
by taking or not taking such action.

 

    A-10 

     

    

 

15.            Trustee
Dealings with the Issuer

 

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

 

16.            No
Recourse Against Others

 

No director, officer, employee, incorporator or holder
of any equity interests in the Issuer or of any Guarantor or any other direct or indirect parent, as such, shall have any liability for
any obligations of the Issuer or the Guarantors under the Securities, the Indenture or the Guarantees or for any claim based on, in respect
of, or by reason of, such obligations or their creation. Each Holder of Securities by accepting a Security waives and releases all such
liability. The waiver and release are part of the consideration for issuance of the Securities.

 

17.            Authentication

 

This Security shall not be valid until an authorized
signatory of the Trustee (or an authenticating agent) manually signs the certificate of authentication on the other side of this Security.

 

18.            Abbreviations

 

Customary abbreviations may be used in the name of
a Holder or an assignee, such as TEN COM (=tenants in common), TEN ENT (=tenants by the entireties), JT TEN (=joint tenants with rights
of survivorship and not as tenants in common), CUST (=custodian), and U/G/M/A (=Uniform Gift to Minors Act).

 

19.            Governing
Law

 

THIS SECURITY SHALL BE GOVERNED BY, AND CONSTRUED
IN ACCORDANCE WITH, THE INTERNAL LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED IN SUCH STATE WITHOUT
REGARD TO CONFLICTS OF LAW PRINCIPLES THEREOF TO THE EXTENT THE LAW OF ANOTHER JURISDICTION WOULD BE APPLIED THEREBY.

Ladies and Gentlemen:

 

This certificate is delivered to request a transfer
of $[       ] principal amount of the 4.875% Senior Notes due 2029 (the “Securities”)

Upon transfer, the Securities would be registered

	Taxpayer ID Number:	 	 

 

The undersigned represents and warrants to you that:

 

1.            We
are an institutional “accredited investor” (as defined in Rule 501(a)(1), (2), (3) or (7) under the
Securities Act of 1933, as amended (the “Securities Act”)), purchasing for our own account or for the account of such
an institutional “accredited investor” at least $250,000 principal amount of the Securities, and we are acquiring the
Securities not with a view to, or for offer or sale in connection with, any distribution in violation of the Securities Act. We have such
knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of our investment in the
Securities, and we invest in or purchase securities similar to the Securities in the normal course of our business. We, and any accounts
for which we are acting, are each able to bear the economic risk of our or its investment.

2.            We
understand that the Securities have not been registered under the Securities Act and, unless so registered, may not be sold except as
permitted in the following sentence. We agree on our own behalf and on behalf of any investor account for which we are purchasing Securities
to offer, sell or otherwise transfer such Securities prior to the date that is one year after the later of the date of original issue
and the last date on which the Issuer or any affiliate of the Issuer was the owner of such Securities (or any predecessor thereto) (the
 “Resale Restriction Termination Date”) only (a) to the Issuer, (b) pursuant to a registration statement that
has been declared effective under the Securities Act, (c) in a transaction complying with the requirements of Rule 144A under
the Securities Act (“Rule 144A”), to a person we reasonably believe is a qualified institutional buyer under Rule 144A
(a “QIB”) that is purchasing for its own account or for the account of a QIB and to whom notice is given that the transfer
is being made in reliance on Rule 144A, (d) pursuant to offers and sales that occur outside the United States within the meaning
of Regulation S under the Securities Act, (e) to an institutional “accredited investor” within the meaning of Rule 501(a)(1),
(2), (3) or (7) under the Securities Act that is purchasing for its own account or for the account of such an institutional
 “accredited investor,” in each case in a minimum principal amount of Securities of $250,000, or (f) pursuant to any other
available exemption from the registration requirements of the Securities Act, subject in each of the foregoing cases to any requirement
of law that the disposition of our property or the property of such investor account or accounts be at all times within our or their control
and in compliance with any applicable state securities laws. The foregoing restrictions on resale will not apply subsequent to the Resale
Restriction Termination Date. If any resale or other transfer of the Securities is proposed to be made pursuant to clause (e) above
prior to the Resale Restriction Termination Date, the transferor shall deliver a letter from the transferee substantially in the form
of this letter to the Issuer and the Trustee, which shall provide, among other things, that the transferee is an institutional “accredited
investor” within the meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act and that it is acquiring
such Securities for investment purposes and not for distribution in violation of the Securities Act. Each purchaser acknowledges that
the Issuer and the Trustee reserve the right prior to the offer, sale or other transfer prior to the Resale Restriction Termination Date
of the Securities pursuant to clause (d), (e) or (f) above to require the delivery of an opinion of counsel, certifications
or other information satisfactory to the Issuer and the Trustee.
