Subsidiary incurs, assumes, guarantees, redeems, retires or extinguishes any Indebtedness or issues or redeems Disqualified Stock or preferred
stock subsequent to the commencement of the Applicable Measurement Period but on or prior to the Applicable Calculation Date, then the
Fixed Charge Coverage Ratio shall be calculated giving pro forma effect to such incurrence, assumption, guarantee, redemption,
retirement or extinguishment of Indebtedness, or such issuance or redemption of Disqualified Stock or preferred stock (in each case, including
a pro forma application of the net proceeds therefrom), as if the same had occurred at the beginning of the Applicable Measurement
Period; provided, however, that the pro forma calculation shall not give effect to any Indebtedness incurred on such
determination date pursuant to the provisions described in Section 1011(b) (other than Indebtedness incurred pursuant to Section 1011(b)(14));

to treat all or any portion of the commitment under any Indebtedness which is to be incurred, as being incurred as of the Applicable Calculation

Ratio, Investments, acquisitions, dispositions, mergers, consolidations and disposed operations (as determined in accordance with GAAP)
that have been made by the Issuer or any Restricted Subsidiary during the Applicable Measurement Period or subsequent to such Applicable

the Issuer or any Restricted Subsidiary since the beginning of such period) shall have made any Investment, acquisition, disposition,
merger, consolidation or disposed operation that would have required adjustment pursuant to this definition, then the Fixed Charge Coverage
Ratio shall be calculated giving pro forma effect thereto for such Applicable Measurement Period as if such Investment, acquisition,
disposition, merger, consolidation or disposed operation had occurred at the beginning of the Applicable Measurement Period.

For purposes of this definition, whenever pro
forma effect is to be given to a transaction, the pro forma calculations shall be made in good faith by a responsible
financial or accounting officer of the Issuer (and may include, for the avoidance of doubt and without duplication, cost savings and
operating expense reductions resulting from such Investment, acquisition, merger or consolidation which is being given pro forma effect
that have been or are expected to be realized). If any Indebtedness bears a floating rate of interest and is being given pro
forma effect, the interest on such Indebtedness shall be calculated as if the rate in effect on the Applicable Calculation Date
had been the applicable rate for the entire period (taking into account for such entire period, any Hedging Obligation applicable to
such Indebtedness with a remaining term of 12 months or longer, and in the case of any Hedging Obligation applicable to such
Indebtedness with a remaining term of less than 12 months, taking into account such Hedging Obligation to the extent of its
remaining term). 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 the Issuer to be the rate of interest implicit in such Capitalized Lease Obligation
in accordance with GAAP. For purposes of making the computation referred to above, interest on any Indebtedness under revolving
credit facilities computed on a pro forma basis shall be computed based upon the average daily balance of such Indebtedness
during the applicable period; or, if lower, the maximum commitments under such revolving credit facilities as of the Applicable
Calculation Date. 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 the Issuer may designate.

election, references herein to GAAP and GAAP concepts shall thereafter be construed to refer to IFRS and corresponding IFRS concepts (except

any calculation or determination in this Indenture that requires the application of GAAP for periods that include fiscal quarters ended
prior to the Issuer’s election to apply IFRS shall remain as previously calculated or determined in accordance with GAAP. The Issuer
shall give written notice of any such election made in accordance with this definition to the Trustee and the Holders. For the avoidance
of doubt, solely making an election (without any other action) referred to in this definition will not be treated as an incurrence of
Indebtedness.

SECTION 105.        Acts
of Holders.

 

(a)                
Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or
taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in
person or by agents duly appointed in writing; and, except as herein otherwise expressly provided, such action shall become effective
when such instrument or instruments are delivered to the Trustee and, where it is hereby expressly required, to the Issuer. Such instrument
or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act”
of the Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent
shall be sufficient for any purpose of this Indenture and conclusive in favor of the Trustee and the Issuer, if made in the manner provided
in this Section 105.

 

(b)               
The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness
of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying
that the individual signing such instrument or writing acknowledged to him the execution thereof. Where such execution is by a signer
acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of authority.

in any other manner that the Trustee deems sufficient.

 

(c)

the Issuer may, at its option, fix in advance a record date for the determination of Holders entitled to give such request, demand, authorization,
direction, notice, consent, waiver or other Act, but the Issuer shall have no obligation to do so. Such record date shall be a date not
earlier than the date 30 days prior to the first solicitation of Holders generally in connection therewith and not later than the date
such solicitation is completed. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver
or other Act may be given before or after such record date, but only the Holders of record at the close of business on such record date
shall be deemed to be Holders for the purposes of determining whether Holders of the requisite proportion of Outstanding Notes have authorized
or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other Act, and for that purpose the
Outstanding Notes shall be computed as of such record date; provided, that no such authorization, agreement or consent by the Holders
on such record date shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later
than eleven months after the record date. Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder
of any Note shall bind every future Holder of the same Note and the Holder of every Note issued upon the registration of transfer thereof

Guarantor in reliance thereon, whether or not notation of such action is made upon such Note.

waiver or other Act of Holders or other document provided or permitted by this Indenture to be made upon, given or furnished to, or filed
with,

 

(1)               
the Trustee by any Holder or by the Issuer or any Guarantor shall be sufficient for every purpose hereunder if made, given, furnished
or filed in writing via facsimile, email in PDF format or mailed, first class postage prepaid, or delivered by recognized overnight courier,
to or with the Trustee at the Corporate Trust Office; or

 

(2)               
the Issuer or any Guarantor by the Trustee or by any Holder shall be sufficient for every purpose hereunder (unless otherwise herein
expressly provided) if made, given, furnished or delivered in writing via facsimile, or email in PDF or mailed, first class postage prepaid,
or delivered by recognized overnight courier, to the Issuer or such Guarantor addressed to BWX Technologies, Inc., 800 Main Street, 4th
Floor, Lynchburg, VA 24504, or at any other address previously furnished in writing to the Trustee by the Issuer or such Guarantor.

as specified in writing to the Trustee by the authorized representative), in English. The Issuer agrees to assume all risks arising out
of the use of using digital signatures and electronic methods to submit communications to the Trustee, including without limitation the
risk of the Trustee acting on unauthorized instructions, and the risk of interception and misuse by third parties.

to the Trustee at the address show above. Any Person may change its address by giving notice of such change as set forth herein.

 

SECTION 107.        
Notice to Holders; Waiver. Where this Indenture provides for notice of any event to Holders by the Issuer or the Trustee,
such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing and delivered electronically or mailed,
first class postage prepaid, to each Holder affected by such event, at his address as it appears in the Note Register, not later than
the latest date, and not earlier than the earliest date, prescribed for the giving of such notice. In any case where notice to Holders
is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect
the sufficiency of such notice with respect to other Holders. Notices given by publication shall be deemed given on the first date on
which publication is made, notices given by first-class mail, postage prepaid, shall be deemed given five calendar days after mailing;
notices sent by overnight delivery service will be deemed given when delivered; and notices given electronically shall be deemed given
when sent. Any notices required to be given to the holders of Notes that are in global form will be given to the Depository.

 

The Trustee agrees to accept and act upon instructions
or directions pursuant to this Indenture sent by unsecured e-mail, pdf, facsimile transmission or other similar unsecured electronic methods,
provided, however, that the Trustee shall have received an incumbency certificate listing Persons designated to give such
instructions or directions and containing specimen signatures of such designated Persons, which such incumbency certificate shall be amended
and replaced whenever a Person is to be added or deleted from the listing. If the Issuer elects to give the Trustee e-mail or facsimile
instructions (or instructions by a similar electronic method) and the Trustee in its discretion elects to act upon such instructions,
the Trustee’s understanding of such instructions shall be deemed controlling. 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
such instructions conflict or are inconsistent with a subsequent written instruction. The Issuer agrees to assume all risks 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.

 

In case by reason of the suspension of or irregularities
in regular mail service or by reason of any other cause, it shall be impracticable to mail notice of any event to Holders when such notice
is required to be given pursuant to any provision of this Indenture, then any manner of giving such notice as shall be satisfactory to
the Trustee shall be deemed to be a sufficient giving of such notice for every purpose hereunder.

 

Where this Indenture provides for notice in any
manner, such notice may be waived in writing by the Person entitled to receive such notice, either before or after the event, and such
waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not
be a condition precedent to the validity of any action taken in reliance upon such waiver.

 

SECTION 108.        
Effect of Headings and Table of Contents. The Article and Section headings herein and the Table of Contents and the reconciliation
and tie between the TIA and this Indenture are for convenience of reference only, are not intended to be considered a part hereof and

SECTION 113.        
Legal Holidays. In any case where any Interest Payment Date, Redemption Date or Stated Maturity or Maturity of any Note
shall not be a Business Day, then (notwithstanding any other provision of this Indenture or of the Notes) payment of principal (or premium,
if any) or interest need not be made on such date, but may be made on the next succeeding Business Day with the same force and effect
as if made on the Interest Payment Date, Redemption Date, or at the Stated Maturity or Maturity; provided, that no interest shall
accrue for purposes of such payment for the period from and after such Interest Payment Date, Redemption Date, Stated Maturity or Maturity,
as the case may be.

SECTION 115.        
Trust Indenture Act Controls. If any provision of this Indenture limits, qualifies or conflicts with another provision which

by facsimile or PDF shall be deemed to be their original signatures for all purposes.

SECTION 202.        
Execution, Authentication, Delivery and Dating. The Notes shall be executed on behalf of the Issuer by at least one Officer.
The signature of any Officer on the Notes may be manual or facsimile signatures of the present or any future such authorized officer and
may be imprinted or otherwise reproduced on the Notes.

 

Notes bearing the manual or facsimile signature
of an individual who was at any time the proper officer of the Issuer shall bind the Issuer, notwithstanding that such individual has
ceased to hold such office prior to the authentication and delivery of such Notes or did not hold such office at the date of such Notes.

 

At any time and from time to time after the execution
and delivery of this Indenture, the Issuer may deliver Notes executed by the Issuer to the Trustee for authentication, together with an
Issuer Order for the authentication and delivery of such Notes, and the Trustee in accordance with such Issuer Order shall authenticate
and deliver such Notes.

 

On the Issue Date, the Issuer shall deliver the
Initial Notes in the aggregate principal amount of $400,000,000 executed by the Issuer to the Trustee for authentication, together with
an Issuer Order for the authentication and delivery of such Notes, specifying the principal amount and registered holder of each Note,
directing the Trustee to authenticate the Notes and deliver the same to the Persons named in such Issuer Order and the Trustee in accordance
with such Issuer Order shall authenticate and deliver such Initial Notes. At any time and from time to time after the Issue Date, the
Issuer may deliver Additional Notes executed by the Issuer to the Trustee for authentication, together with an Issuer Order for the authentication
and delivery of such Additional Notes, specifying the principal amount of and registered holder of each Note, directing the Trustee to
authenticate the Additional Notes and deliver the same to the Persons in such Issuer Order and the Trustee in accordance with such Issuer
Order shall authenticate and deliver such Additional Notes. In each case (other than the issuance of the Initial Notes), the Trustee shall
receive an Officer’s Certificate and an Opinion of Counsel of the Issuer that it may reasonably require in connection with such
authentication of Notes. Such Issuer Order shall specify the date on which the original issue of Notes is to be authenticated. In authenticating
Additional Notes and accepting the additional responsibilities under this Indenture in relation to such Additional Notes, the Trustee
shall receive, and be fully protected in relying on:

 

(a)
       A copy of the resolution or resolutions of the Board of Directors in or pursuant to which the terms and form of the Notes were
established, certified by the Secretary or an Assistant Secretary of the Issuer as having been duly adopted by the Board of
Directors and to be in full force and effect as of the date of such certificate, or if the terms and form of such Notes are
established by an Officer’s Certificate pursuant to general authorization of the Board of Directors, such Officer’s
Certificate;

 

    -39-

     

    

 

(b)
       an executed supplemental indenture, if any;

 

(c)
       an Officer’s Certificate delivered in accordance with Section 103; and

 

(d)
      an Opinion of Counsel which shall state:

 

(1)
      that the form and terms of such Notes have been established in conformity with the other provisions of this Indenture; and

 

(2)
      that such Notes, when authenticated and delivered by the Trustee 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.

 

Each Note shall be dated the date of its authentication.

 

No Note shall be entitled to any benefit under
this Indenture or be valid or obligatory for any purpose unless there appears on such Note a certificate of authentication substantially
in the form provided for herein duly executed by the Trustee by manual signature of an authorized signatory, and such certificate upon
any Note shall be conclusive evidence, and the only evidence, that such Note has been duly authenticated and delivered hereunder and is
entitled to the benefits of this Indenture.

 

In case the Issuer or any Guarantor, pursuant to
Article Eight of this Indenture, shall be consolidated or merged with or into any other Person or shall convey, transfer, lease or otherwise
dispose of its properties and assets substantially as an entirety to any Person, and the successor Person resulting from such consolidation,
or surviving such merger, or into which the Issuer or such Guarantor shall have been merged, or the Person which shall have received a
conveyance, transfer, lease or other disposition as aforesaid, shall have executed a supplemental indenture hereto with the Trustee pursuant
to Article Eight of this Indenture, any of the Notes authenticated or delivered prior to such consolidation, merger, conveyance, transfer,
lease or other disposition may, from time to time, at the request of the successor Person, be exchanged for other Notes executed in the
name of the successor Person with such changes in phraseology and form as may be appropriate, but otherwise in substance of like tenor
as the Notes surrendered for such exchange and of like principal amount; and the Trustee, upon Issuer Request of the successor Person,
shall authenticate and deliver Notes as specified in such request for the purpose of such exchange. If Notes shall at any time be authenticated
and delivered in any new name of a successor Person pursuant to this Section 202 in exchange or substitution for or upon registration
of transfer of any Notes, such successor Person, at the option of the Holders but without expense to them, shall provide for the exchange
of all Notes at the time Outstanding for Notes authenticated and delivered in such new name.

 

The Trustee may appoint an authenticating agent
acceptable to the Issuer to authenticate Notes. An authenticating agent may authenticate Notes 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 an Agent to deal with Holders or an affiliate of the Issuer.

THE NOTES

 

SECTION 301.        
Title and Terms. The aggregate principal amount of Notes which may be authenticated and issued under this Indenture is not
limited; provided that any Additional Notes issued under this Indenture are issued in accordance with Sections 202, 312 and 1011
hereof, as part of the same series as the Initial Notes.

 

The terms and provisions contained in the Notes
shall constitute, and are hereby expressly made, a part of this Indenture, and the Issuer, the Guarantors and the Trustee, by their execution
and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. However, to the extent any provision
of any Note conflicts with the express provisions of this Indenture, the provisions of this Indenture shall govern and be controlling.

 

The Notes shall be known and designated as the
 “4.125% Senior Notes due 2029” of the Issuer. The Stated Maturity of the Notes shall be April 15, 2029, and the Notes shall
bear interest at the rate of 4.125% per annum from the Issue Date, or from the most recent Interest Payment Date to which interest has
been paid or duly provided for, payable on October 15, 2021 and semi-annually thereafter on April 15 and October 15 in each year and at
said Stated Maturity, until the principal thereof is paid or duly provided for and to the Person in whose name the Note (or any Predecessor
Note) is registered at the close of business on April 1 and October 1 immediately preceding such Interest Payment Date (each, a “Regular
Record Date”).

 

The principal of (and premium, if any) and interest
on the Notes shall be payable at the offices or agencies of the Issuer set forth in Section 302, or, at the option of the Issuer, payment
of interest may be made by check mailed to the Holders of the Notes at their respective addresses set forth in the Note Register of Holders;
provided that all payments of principal, premium, if any, and interest with respect to Notes represented by one or more permanent
Global Notes registered in the name of or held by the Depository or its nominee will be made by wire transfer of immediately available
funds to the Depository.

 

Holders shall have the right to require the Issuer
to purchase their Notes, in whole or in part, in the event of a Change of Control pursuant to Section 1016. The Notes shall be subject
to repurchase pursuant to an Asset Sale Offer as provided in Section 1017.

 

The Notes shall be redeemable as provided in Article
Eleven.

 

The due and punctual payment of principal of (and
premium, if any) and interest on the Notes payable by the Issuer is irrevocably unconditionally guaranteed, to the extent set forth herein,
by each of the Guarantors.

 

SECTION 302.        
Note Registrar, Transfer Agent and Paying Agent. The Issuer shall maintain one or more Paying Agents for the Notes in New
York. The Issuer hereby appoints the Trustee as the initial Paying Agent.

 

The Issuer shall be responsible for making calculations
called for under the Notes, including but not limited to determination of redemption price or other amounts payable on the Notes. The
Issuer will make the calculations in good faith and, absent manifest error, its calculations will be final and binding on the Holders.
The Issuer will provide a schedule of its calculations to the Trustee when requested by the Trustee, and the Trustee is entitled to rely
conclusively on the accuracy of the Issuer’s calculations without independent verification. The Trustee shall forward the Issuer’s
calculations to any Holder of the Notes upon the written request of such Holder.

 

The Issuer will also maintain one or more registrars
(each, a “Note Registrar”) with offices in New York. The Issuer will also maintain a transfer agent (each, a “Transfer
Agent”) in New York. The Issuer hereby appoints the Trustee as the initial Note Registrar and Transfer Agent. The Note Registrar
and the Transfer Agent shall keep a register of the Notes and of their transfer and exchange (the register maintained in such office and
in any other office or agency designated pursuant to Section 1002 being herein sometimes referred to as the “Note Register”).
The Note Register shall be in written form or any other form capable of being converted into written form within a reasonable time. At
all reasonable times, the Note Register shall be open to inspection by the Trustee. The Issuer may change the Paying Agents, the Note
Registrars or the Transfer Agents without prior notice to the Holders. The Issuer may have one or more co-registrars and one or more additional
paying agents. The term “Note Registrar” includes any co-registrars.

 

The Issuer shall enter into an appropriate agency
agreement with any Note Registrar or Paying Agent not a party to this Indenture. The agreement shall implement the provisions of this
Indenture that relate to such agent.

 

    -41-

     

    

 

The Issuer shall notify the Trustee in writing of the name and address
of any such agent. If the Issuer fails to maintain a Note Registrar or Paying Agent, the Trustee shall act as such and shall be entitled
to appropriate compensation therefor pursuant to Section 607. The Issuer or any Affiliate thereof may act as Paying Agent or Note Registrar.

 

The Issuer acknowledges that neither the Trustee
nor any Agent makes any representations as to the interpretation or characterization of the transactions herein undertaken for tax or
any other purpose, in any jurisdiction.

 

SECTION 303.        
Denominations. The Notes shall be issuable only in registered form without coupons and only in denominations of $2,000 and
any integral multiples of $1,000 in excess thereof.

 

SECTION 304.        
Temporary Notes. Pending the preparation of definitive Notes, the Issuer may execute, and upon Issuer Order the Trustee
shall authenticate and deliver, temporary Notes which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any
authorized denomination, substantially of the tenor of the definitive Notes in lieu of which they are issued and with such appropriate
insertions, omissions, substitutions and other variations as the officers executing such Notes may determine, as conclusively evidenced
by their execution of such Notes.

 

If temporary Notes are issued, the Issuer will
cause definitive Notes to be prepared without unreasonable delay. After the preparation of definitive Notes, the temporary Notes shall
be exchangeable for definitive Notes upon surrender of the temporary Notes at the office or agency of the Issuer designated for such purpose
pursuant to Section 1002, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Notes, the Issuer
shall execute and the Trustee shall authenticate and deliver in exchange therefor a like principal amount of definitive Notes of authorized
denominations. Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits under this Indenture as
definitive Notes.

 

SECTION 305.        
Registration of Transfer and Exchange. Upon surrender for registration of transfer of any Note at the office or agency of
the Issuer designated pursuant to Section 1002, the Issuer shall execute, and the Trustee shall authenticate and deliver, in the name
of the designated transferee or transferees, one or more new Notes of any authorized denomination or denominations of a like aggregate
principal amount.

 

At the option of the Holder, Notes may be exchanged
for other Notes of any authorized denomination and of a like aggregate principal amount, upon surrender of the Notes to be exchanged at
such office or agency together with endorsement, instrument of exchange and such other required deliverables in form satisfactory to the
Issuer, the Note Registrar and the Trustee. Whenever any Notes are so surrendered for exchange, the Issuer shall execute, and upon receipt
of an Issuer Order, the Trustee shall authenticate and deliver in accordance with such Issuer Order, the Notes which the Holder making
the exchange is entitled to receive.

 

All Notes issued upon any registration of transfer
or exchange of Notes shall be the valid obligations of the Issuer, evidencing the same debt, and entitled to the same benefits under this
Indenture, as the Notes surrendered upon such registration of transfer or exchange.

 

Every Note presented or surrendered for registration
of transfer or for exchange shall (if so required by the Issuer, the Note Registrar or the Trustee) be duly endorsed, or be accompanied
by written instruments of transfer, in form satisfactory to the Issuer, the Note Registrar and the Trustee, duly executed by the Holder
thereof or his attorney duly authorized in writing.

 

No service charge shall be made for any registration
of transfer or exchange or redemption of Notes, but the Issuer may require payment of a sum sufficient to cover any taxes, fees or other
governmental charge that may be imposed in connection with any registration of transfer or exchange of Notes, other than exchanges pursuant
to Section 202, 304, 906, 1016, 1017 or 1108 not involving any transfer.

 

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 or under applicable
law with respect to any transfer of any interest in any Note (including any transfers between or among Depository participants or
beneficial owners of interests in any Notes in global form) 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 to examine the same to determine substantial compliance as to form with the express requirements hereof.

 

    -42-

     

    

 

SECTION 306.        
Mutilated, Destroyed, Lost and Stolen Notes. If (1) any mutilated Note is surrendered to the Trustee, or (2) the Issuer
and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Note, and there is delivered to the Issuer
and the Trustee such security and/or indemnity to save each of them harmless from any claim, loss, cost or liability resulting from such
lost or stolen Note, then, in the absence of written notice to the Issuer or the Trustee that such Note has been acquired by a Protected
Purchaser (as defined in Section 8-303 of the Uniform Commercial Code) (a “Protected Purchaser”), the Issuer shall
execute and upon Issuer Order the Trustee shall authenticate and deliver, in exchange for any such mutilated Note or in lieu of any such
destroyed, lost or stolen Note, a new Note of like tenor and principal amount, bearing a number not contemporaneously outstanding.

 

In case any such mutilated, destroyed, lost or
stolen Note has become or is about to become due and payable, the Issuer in its discretion may, instead of issuing a new Note, pay such
Note.

 

Upon the issuance of any new Note under this Section
306, the Issuer may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation
thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith.

 

Every new Note issued pursuant to this Section
306 in lieu of any mutilated, destroyed, lost or stolen Note shall constitute an original additional contractual obligation of the Issuer
and each Guarantor, whether or not the mutilated, destroyed, lost or stolen Note shall be at any time enforceable by anyone, and shall
be entitled to all benefits of this Indenture equally and proportionately with any and all other Notes duly issued hereunder.

 

The provisions of this Section 306 are exclusive
and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed,
lost or stolen Notes.

 

SECTION 307.        
Payment of Interest; Interest Rights Preserved.

 

(a)          
Interest on any Note which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid
to the Person in whose name such Note (or one or more Predecessor Notes) is registered at the close of business on the Regular Record
Date for such interest at the office or agency of the Issuer maintained for such purpose pursuant to Section 1002; provided that,
subject to Section 301 hereof, each installment of interest may at the Issuer’s option be paid by (1) mailing a check for such interest,
payable to or upon the written order of the Person entitled thereto pursuant to Section 308, to the address of such Person as it appears
in the Note Register or (2) transfer to an account maintained by the payee; provided that payment by wire transfer of immediately
available funds shall be required with respect to principal of, premium on, if any, and interest on, all Notes in global form and all
other Notes the Holders of which shall have provided wire transfer instructions to the Issuer and the Paying Agent. If paying principal,
premium, or interest on a global note, not later than 10:00 a.m. (New York City time) on the due date of any principal of or interest
on any Notes of a series, or any redemption or purchase price of the Notes, the Issuer will deposit with the Paying Agent (and the Paying
Agent shall have received such funds by such time) money in immediately available funds sufficient to pay such amounts, provided
that if the Issuer, a Guarantor or any of their Subsidiaries is acting as paying agent, it will, on or before each due date, segregate
and hold in a separate trust fund for the benefit of the Holders of the Notes of such series a sum of money sufficient to pay such amounts
until paid to such Holders or otherwise disposed of as provided in this Indenture.

 

(b)         
Any interest on any Note which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date shall
forthwith cease to be payable to the Holder on the Regular Record Date by virtue of having been such Holder, and such defaulted interest
and (to the extent lawful) interest on such defaulted interest at the rate borne by the Notes (such defaulted interest and interest thereon
herein collectively called “Defaulted Interest”) may be paid by the Issuer, at its election in each case, as provided
in clause (1) or (2) below:

 

    -43-

     

    

 

(1)        
 the Issuer may elect to make payment of any Defaulted Interest to the Persons in whose names the Notes (or their respective Predecessor
Notes) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed
in the following manner. The Issuer shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each
Note and the date of the proposed payment, and at the same time the Issuer shall deposit with the Trustee an amount of money equal to
the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee
for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons
entitled to such Defaulted Interest as in this clause (1) provided. Thereupon the Trustee shall fix a Special Record Date for the payment
of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and
not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Issuer
of such Special Record Date, and in the name and at the expense of the Issuer, shall cause notice of the proposed payment of such Defaulted
Interest and the Special Record Date therefor to be given in the manner provided for in Section 107, not less than 10 days prior to such
Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so given,
such Defaulted Interest shall be paid to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at
the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (2); and

 

(2)        
the Issuer may make payment of any Defaulted Interest in any other lawful manner not inconsistent with the requirements of any
securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange, if, after written notice
given by the Issuer to the Trustee of the proposed payment pursuant to this clause (2), such manner of payment shall be deemed practicable
by the Trustee.

 

(c)         
Subject to the foregoing provisions of this Section 307, each Note delivered under this Indenture upon registration of transfer
of or in exchange for or in lieu of any other Note shall carry the rights to interest accrued and unpaid, and to accrue, which were carried
by such other Note.

 

SECTION 308.        
Persons Deemed Owners. Prior to the due presentment of a Note for registration of transfer, the Issuer, any Guarantor, the
Trustee and any agent of the Issuer or the Trustee may treat the Person in whose name such Note is registered as the owner of such Note
for the purpose of receiving payment of principal of (and premium, if any) and (subject to Sections 305 and 307) interest on such Note
and for all other purposes whatsoever, whether or not such Note be overdue, and none of the Issuer, the Trustee or any agent of the Issuer
or the Trustee shall be affected by notice to the contrary.

 

SECTION 309.        
Cancellation. All Notes surrendered for payment, redemption, registration of transfer or exchange shall, if surrendered
to any Person other than the Trustee, be delivered to the Trustee and shall be cancelled by the Trustee in accordance with its customary
procedures. The Issuer may at any time deliver to the Trustee for cancellation any Notes previously authenticated and delivered hereunder
which the Issuer may have acquired in any manner whatsoever, and may deliver to the Trustee (or to any other Person for delivery to the
Trustee) for cancellation any Notes previously authenticated hereunder which the Issuer has not issued and sold, and all Notes so delivered
shall be cancelled by the Trustee in accordance with its customary procedures. If the Issuer shall so acquire any of the Notes, however,
such acquisition shall not operate as a redemption or satisfaction of the indebtedness represented by such Notes unless and until the
same are surrendered to the Trustee for cancellation. No Notes shall be authenticated in lieu of or in exchange for any Notes cancelled
as provided in this Section 309, except as expressly permitted by this Indenture. All cancelled Notes held by the Trustee shall be disposed
of by the Trustee in accordance with its customary procedures. Evidence or confirmation of the cancellation of such Notes shall be delivered
to the Issuer by the Trustee upon the Issuer’s request. The Note Registrar shall maintain a record of all cancelled Notes in accordance
with its customary procedures. The Note Registrar shall provide the Issuer a list of all Notes that have been cancelled from time to time
as requested by the Issuer.

 

SECTION 310.        
Computation of Interest. Interest on the Notes shall be computed on the basis of a 360-day year of twelve 30-day months.

 

    -44-

     

    

 

SECTION 311.        
Transfer and Exchange. The Notes shall be issued in registered form and shall be transferable only upon the surrender of
a Note for registration of transfer. When a Note is presented to the Note Registrar or a co-registrar with a request to register a transfer,
the Note Registrar shall register the transfer as requested if the requirements of this Indenture and Section 8-401(a) of the Uniform
Commercial Code are met. When Notes are presented to the Note Registrar or a co-registrar with a request to exchange them for an equal
principal amount of Notes of other denominations, the Note Registrar shall make the exchange as requested if the same requirements are
met.

 

The Issuer shall not be required, and without the
prior written consent of the Issuer, the Note Registrar shall not be required, to register the transfer of or exchange of any Note (1)
during a period beginning at the opening of business 15 days before provision of a notice of redemption of Notes and ending at the close
of business on the day of such provision, (2) selected for redemption in whole or in part, (3) that has been tendered in a Change of Control
Offer, Asset Sale Offer or other tender offer and (4) beginning at the opening of business on any record date and ending on the close
of business on the related Interest Payment Date.

 

SECTION 312.        
CUSIP, ISIN and Common Code Numbers. The Issuer in issuing the Notes may use CUSIP, ISINs and “Common Code”
numbers (in each case, if then generally in use) in addition to serial numbers, and, if so, the Trustee shall use such CUSIP, ISINs and
 “Common Code” numbers in addition to serial numbers in notices of redemption, repurchase or other notices to Holders as a
convenience to Holders; provided that the Trustee shall have no liability for any defect in such numbers as they appear on any
Note, notice or elsewhere, and provided, further, that any such notice may state that no representation is made as to the
correctness of such CUSIP, ISINs and “Common Code” numbers either as printed on the Notes or as contained in any notice of
a redemption or repurchase and that reliance may be placed only on the serial or other identification numbers printed on the Notes, and
any such redemption or repurchase shall not be affected by any defect in or omission of such numbers. The Issuer will promptly notify
the Trustee in writing of any change in the CUSIP, ISINs and “Common Code” numbers applicable to the Notes.

 

SECTION 313.        
Issuance of Additional Notes. The Issuer may, subject to Section 1011 of this Indenture, issue additional Notes having identical
terms and conditions to the Initial Notes issued on the Issue Date (the “Additional Notes”). The Initial Notes issued
on the Issue Date and any Additional Notes subsequently issued shall be treated as a single class for all purposes under this Indenture;
provided, that Additional Notes will not be issued with the same CUSIP number, if any, as Initial Notes unless such Additional
Notes are fungible with Initial Notes for U.S. Federal income tax purposes.

 

SECTION 314.        
Global Securities.

 

Neither the Trustee nor any Agent shall have any
responsibility or liability for any actions taken or not taken by the Depository.

(1)         
either,

 

(A)        
all Notes theretofore authenticated and delivered (other than (i) Notes which have been destroyed, lost or stolen and which have
been replaced or paid as provided in Section 306 and (ii) Notes for whose payment money has theretofore been deposited in trust with the
Trustee or any Paying Agent or segregated and held in trust by the Issuer and thereafter repaid to the Issuer or discharged from such
trust, as provided in Section 1003) have been delivered to the Trustee for cancellation; or

 

    -45-

     

    

 

(B)        
 all such Notes not theretofore delivered to the Trustee for cancellation,

 

(i)          
have become due and payable by reason of the making of a notice of redemption pursuant to Section 1105 or otherwise, or

 

(ii)         
will become due and payable at their Stated Maturity within one year, or

 

(iii)        
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, in the case of (i), (ii) or
(iii) above, has irrevocably deposited or caused to be deposited with the Trustee in trust solely for the benefit of the Holders of the
Notes, cash in U.S. dollars, U.S. dollar-denominated Government Securities, or a combination thereof, in such amounts as will be sufficient
without consideration of any reinvestment of interest to pay and discharge the entire indebtedness on such Notes not theretofore delivered
to the Trustee for cancellation, for principal, premium, if any, and accrued interest to the Stated Maturity or Redemption Date, as the
case may be;

 

(2)        
no Default or Event of Default (other than that resulting from borrowing funds to be applied to make such deposit and any similar
and simultaneous deposit relating to other Indebtedness and, in each case, the granting of Liens in connection therewith) with respect
to this Indenture or the Notes issued hereunder shall have occurred and be continuing on the date of such deposit or shall occur as a
result of such deposit and such deposit shall not result in a breach or violation of, or constitute a default under the Senior Credit
Facility or any other material agreement or instrument (other than this Indenture) to which the Issuer or any Guarantor is a party or
by which the Issuer or any Guarantor is bound (other than that resulting from borrowing funds to be applied to make such deposit and any
similar and simultaneous deposit relating to other Indebtedness and, in each case, the granting of Liens in connection therewith);

 

(3)        
the Issuer has paid or caused to be paid all sums payable by it under this Indenture;

 

(4)        
the Issuer has delivered irrevocable instructions to the Trustee under this Indenture to apply the deposited money toward the payment
of such Notes at the Stated Maturity or the Redemption Date, as the case may be; and

 

(5)        
the Issuer must deliver an Officer’s Certificate and an Opinion of Counsel to the Trustee stating that all conditions precedent
herein to the satisfaction and discharge of this Indenture have been satisfied.

 

Notwithstanding the satisfaction and discharge
of this Indenture, the obligations of the Issuer to the Trustee under Section 607, the obligations of the Issuer to any Authenticating
Agent under Section 612 and, if money or Government Securities shall have been deposited with the Trustee pursuant to subclause (B) of
clause (1) of this Section 401, the obligations of the Trustee under Section 402 and the last paragraph of Section 1003 shall survive
such satisfaction and discharge.

 

SECTION 402.        
Application of Trust Money. Subject to the provisions of the last paragraph of Section 1003, all money or U.S. dollar-denominated
Government Securities deposited with the Trustee pursuant to Section 401 shall be held in trust and applied by it, in accordance with
the provisions of the Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Issuer acting
as its own Paying Agent) of the principal (and premium, if any) and interest for whose payment such money or U.S. dollar-denominated Government
Securities has been deposited with the Trustee; but such money or U.S. dollar-denominated Government Securities need not be segregated
from other funds except to the extent required by law.

If the Trustee or Paying Agent is unable to apply
any money or U.S. dollar-denominated Government Securities in accordance with Section 401 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 and any Guarantor’s obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit
had occurred pursuant to Section 401 until such time as the Trustee or Paying Agent is permitted to apply all such money or U.S. dollar-denominated
Government Securities in accordance with Section 401; provided that if the Issuer has made any payment of principal of (and premium,
if any) or interest on any Notes because of the reinstatement of its obligations, the Issuer shall be subrogated to the rights of the
Holders of such Notes to receive such payment from the money or U.S. dollar-denominated Government Securities held by the Trustee or Paying
Agent.

SECTION 501.        
Events of Default. “Event of Default,” wherever used herein, means any one of the following events (whatever
the reason for such Event of Default and whether it be voluntary or involuntary or be effected by operation of law or pursuant to any
judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body):

 

(1)        
default in payment when due and payable, upon redemption, acceleration or otherwise, of principal of, or premium, if any, on the
Notes issued under this Indenture;

 

(2)        
default for 30 days or more in the payment when due of interest on or with respect to the Notes issued under this Indenture;

 

(3)        
failure by the Issuer or any Restricted Subsidiary for 60 days after the receipt of written notice given by the Trustee or the
Holders of not less than 25% in principal amount of the Notes then outstanding (with a copy to the Trustee) to comply with any of its
obligations, covenants or agreements (other than a default referred to in clauses (1) and (2) above) contained in this Indenture or the
Notes;

 

(4)        
default under any mortgage, indenture or instrument under which there is issued or by which there is secured or evidenced any Indebtedness
for money borrowed by the Issuer or any Restricted Subsidiary or the payment of which is guaranteed by the Issuer or any Restricted Subsidiary,
other than Indebtedness owed to the Issuer or any Restricted Subsidiary, whether such Indebtedness or guarantee now exists or is created
after the issuance of the Notes, if both:

 

(A)        such default either results from the failure to pay any principal of such Indebtedness at its stated final maturity (after giving
effect to any applicable grace periods) or relates to an obligation other than the obligation to pay principal of any such Indebtedness
at its stated final maturity and results in the holder or holders of such Indebtedness causing such Indebtedness to become due prior to
its stated maturity, and

 

(B)         the principal amount of such Indebtedness, together with the principal amount of any other such Indebtedness in default for failure
to pay principal at stated final maturity (after giving effect to any applicable grace periods), or the maturity of which has been so
accelerated, aggregate $75.0 million or more at any one time outstanding;

 

(5)        
failure by the Issuer or any Significant Subsidiary to pay final judgments aggregating in excess of $75.0 million (net of amounts
covered by insurance policies issued by reputable insurance companies), which final judgments remain unpaid, undischarged and unstayed
for a period of more than 60 days after such judgment becomes final, 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;

 

    -47-

     

    

 

(6)        
 any of the following events with respect to the Issuer or any Significant Subsidiary:

 

(A)       
the Issuer or any Significant Subsidiary pursuant to or within the meaning of any Bankruptcy Law:

 

(i)         
commences a voluntary case;

 

(ii)        
consents to the entry of an order for relief against it in an involuntary case;

 

(iii)       
consents to the appointment of a custodian of it or for any substantial part of its property;

 

(iv)       
takes any comparable action under any foreign laws relating to insolvency; or

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

 

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

(7)        
the Guarantee of any Guarantor that is a Significant Subsidiary shall for any reason cease to be in full force (except as contemplated
by the terms thereof or hereof) and effect or be declared null and void or any responsible officer of any Guarantor that is a Significant
Subsidiary denies that it has any further liability under its Guarantee or gives notice to such effect, other than by reason of the termination
of the related Indenture or the release of any such Guarantee in accordance with this Indenture.

 

SECTION 502.        
Acceleration of Maturity; Rescission and Annulment.

 

(a)         
If any Event of Default (other than an Event of Default specified in Section 501(6) above with respect to the Issuer) occurs and
is continuing under this Indenture, the Trustee or the Holders of at least 25% in principal amount of the Outstanding Notes issued under
this Indenture may declare the principal, premium, if any, interest and any other monetary obligations on all the Outstanding Notes to
be due and payable immediately, by a notice to the Issuer (and to the Trustee if given by Holders).

 

(b)        
Upon the effectiveness of a declaration under 502(a), such principal and interest will be due and payable immediately. Notwithstanding
the foregoing, in the case of an Event of Default arising under Section 501(6) with respect to the Issuer, all Outstanding Notes will
become due and payable without further action or notice. The Trustee may withhold from the Holders notice of any continuing Default or
Event of Default, except a Default or Event of Default relating to the payment of principal, premium, if any, or interest if it determines
that withholding notice is in the interest of the Holders. In addition, the Trustee shall have no obligation to accelerate the Notes if
the Trustee determines acceleration is not in the best interest of the Holders of the Notes.

 

(c)          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 (other than a Regulated
Bank) (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 the Depository 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 shall be deemed a
continuing representation until the resulting Event of Default is cured or otherwise ceases to exist or the notes 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 (5) Business Days of request therefor (a “Verification
Covenant”). In any case in which the Holder is the Depository or its nominee, any Position Representation or Verification
Covenant required hereunder shall be provided by the beneficial owner of the notes in lieu of the Depository or its nominee.

 

    -48-

     

    

 

(d)         
If, following the delivery of a Noteholder Direction, but prior to acceleration of the Outstanding Notes, 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 in 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 Event of Default 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. Until such time as the Trustee has received an Officer’s
Certificate certifying such final and non-appealable determination, the Trustee shall have no duty or obligation to act with respect to
such Noteholder Direction. If, following the delivery of a Noteholder Direction, but prior to acceleration of the Outstanding Notes, 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. Upon receipt of an Officer’s Certificate in accordance with this Section 502, the Trustee shall have no duty
or obligation to act with respect to such Noteholder Direction. 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 Outstanding
Notes 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, with the effect that such Event of Default shall be deemed never
to have occurred, 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.

 

(e)         
Notwithstanding anything in the preceding Sections 502(c) and (d) to the contrary, any Noteholder Direction delivered to the Trustee
during the pendency of an Event of Default as the result of a bankruptcy or similar proceeding shall not require compliance with the foregoing
clauses. In addition, for the avoidance of doubt, the preceding Sections 502(c) and (d) shall not apply to any Holder that is a Regulated
Bank, and the Trustee shall have no duty to verify or determine whether a Holder is a Regulated Bank.

 

(f)         
For the avoidance of doubt, the Trustee shall be entitled to conclusively rely on any Noteholder Direction delivered to it in accordance
with this Section 502, shall have no duty to inquire as to or investigate the accuracy of any representation, including 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 or a direction provided by the Issuer in accordance with Section 5.02(d).

 

(g)        
At any time after a declaration of acceleration has been made and before a judgment or decree for payment of the money due has
been obtained by the Trustee as hereinafter provided in this Article Five, the Holders of a majority in aggregate principal amount of
the Outstanding Notes, by notice to the Trustee, may rescind and annul such declaration and its consequences, so long as such rescission
and annulment would not conflict with any judgment of a court of competent jurisdiction, if:

 

    -49-

     

    

 

(1)         
 the Issuer has paid or deposited with the Trustee a sum sufficient to pay:

 

(A)        
all overdue interest on all Outstanding Notes,

 

(B)        
all unpaid principal of (and premium, if any, on) any Outstanding Notes which has become due otherwise than by such declaration
of acceleration, and interest on such unpaid principal at the rate borne by the Notes,

 

(C)         
to the extent that payment of such interest is lawful, interest on overdue interest at the rate borne by the Notes, and

 

(D)        
all sums paid or advanced by the Trustee hereunder and the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel; and

 

(2)         
Events of Default, other than the non-payment of amounts of principal of (or premium, if any, on) or interest on Notes, which have
become due solely by such declaration of acceleration, have been cured or waived as provided in Section 513,

 

no such rescission shall affect any subsequent default or impair any
right consequent thereon.

 

(h)         
Notwithstanding the preceding paragraph, in the event of any Event of Default specified in Section 501(4) above, such Event of
Default and all consequences thereof (excluding any resulting payment default, other than as a result of acceleration of the Notes) 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,

 

(1)         
the Indebtedness or guarantee that is the basis for such Event of Default has been discharged, or

 

(2)         
the holders thereof have rescinded or waived the acceleration, notice or action (as the case may be) giving rise to such Event
of Default, or

 

(3)          
if the default that is the basis for such Event of Default has been cured.

 

SECTION 503.        
Collection of Indebtedness and Suits for Enforcement by Trustee. The Issuer covenants that if:

 

(1)         
default is made in the payment of any installment of interest on any Note when such interest becomes due and payable and such default
continues for a period of 30 days, or

 

(2)         
default is made in the payment of the principal of (or premium, if any, on) any Note at the Maturity thereof, the Issuer will,
upon demand of the Trustee, pay to the Trustee for the benefit of the Holders of such Notes, the whole amount then due and payable on
such Notes for principal (and premium, if any) and interest, and interest on any overdue principal (and premium, if any) and, to the extent
that payment of such interest shall be legally enforceable, upon any overdue installment of interest, at the rate borne by the Notes,
and, in addition thereto, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

 

If the Issuer fails to pay such amounts forthwith
upon such demand, the Trustee, in its own name as trustee of an express trust, may institute a judicial proceeding for the collection
of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Issuer,
any Guarantor or any other obligor upon the Notes and collect the moneys adjudged or decreed to be payable in the manner provided by law
out of the property of the Issuer, any Guarantor or any other obligor upon the Notes, wherever situated.

 

    -50-

     

    

 

If an Event of Default occurs and is continuing,
the Trustee may proceed to protect and enforce its rights and the rights of the Holders under this Indenture and the Guarantees by such
appropriate judicial proceedings as the Trustee shall deem necessary to protect and enforce any such rights, including seeking recourse
against any Guarantor, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of
any power granted herein, or to enforce any other proper remedy, including seeking recourse against any Guarantor.

 

SECTION 504.        
Trustee May File Proofs of Claim. In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization,
arrangement, adjustment, composition or other judicial proceeding relative to the Issuer or any other obligor including any Guarantor,
upon the Notes or the property of the Issuer or of such other obligor or their creditors, the Trustee (irrespective of whether the principal
of the Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee
shall have made any demand on the Issuer for the payment of overdue principal, premium, if any, or interest) shall be entitled and empowered,
by intervention in such proceeding or otherwise,

 

(1)         
to file and prove a claim for the whole amount of principal (and premium, if any) and interest owing and unpaid in respect of the
Notes and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including
any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders
allowed in such judicial proceeding, and

 

(2)         
to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same;

 

and any custodian, receiver, assignee, trustee, liquidator, sequestrator
or similar official in any such judicial proceeding is hereby authorized by each Holder to make such 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 the Trustee any amount due it for
the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the
Trustee under Section 607.

 

Nothing herein contained 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 Notes 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. The Trustee may, on behalf of the Holders, vote for the election of a trustee in bankruptcy or similar
official and be a member of a creditors’ committee or other similar committee.

 

SECTION 505.        
Trustee May Enforce Claims Without Possession of Notes. All rights of action and claims under this Indenture or the Notes
may be prosecuted and enforced by the Trustee without the possession of any of the Notes or the production thereof in any proceeding relating
thereto, and any such proceeding instituted by the Trustee shall be brought in its own name and as trustee of an express trust, and any
recovery of judgment shall, after provision for the payment of the reasonable compensation, expenses, disbursements and advances of the
Trustee, its agents and counsel, be for the ratable benefit of the Holders in respect of which such judgment has been recovered.

 

SECTION 506.        
Application of Money Collected. Any money or property collected by the Trustee pursuant to this Article Five shall be applied
in the following order, at the date or dates fixed by the Trustee and, in case of the distribution of such money on account of principal
(or premium, if any) or interest, upon presentation of the Notes and the notation thereon of the payment if only partially paid and upon
surrender thereof if fully paid:

 

FIRST: To the payment of all amounts
due the Trustee and its Agents (including any predecessor Trustee) under Section 607;

 

SECOND: To the payment of the
amounts then due and unpaid for principal of (and premium, if any) and interest on the Notes in respect of which or for the benefit of
which such money has been collected, ratably, without preference or priority of any kind, according to the amounts due and payable on
such Notes for principal (and premium, if any) and interest, respectively; and

 

    -51-

     

    

 

THIRD: The balance, if any, to
the Issuer or as a court of competent jurisdiction may direct in writing; provided that all sums due and owing to the Holders and
the Trustee have been paid in full as required by this Indenture.

 

The Trustee may fix a record date and payment date
for any payment to Holders of Notes pursuant to this Section 506.

 

SECTION 507.        
Limitation on Suits. Except to enforce the right to receive payment of principal, premium, if any, or interest when due,
no Holder shall pursue any remedy with respect to this Indenture or the Notes, unless:

 

(1)           
such Holder has previously given the Trustee notice that an Event of Default is continuing;

 

(2)           
Holders of at least 25% in principal amount of the Outstanding Notes have requested the Trustee to pursue the remedy;

 

(3)           
such Holders have provided the Trustee security or indemnity satisfactory to the Trustee against any loss, liability or expense;

 

(4)           
the Trustee has not complied with such request within 60 days after the receipt thereof and the offer of security and/or indemnity
satisfactory to it against any loss, liability or expense; and

 

(5)           
Holders of a majority in principal amount of the Outstanding Notes have not given the Trustee a direction inconsistent with such
request within such 60-day period,

 

it being understood and intended that no one or more Holders shall
have any right in any manner whatever by virtue of, or by availing of, any provision of this Indenture or the Guarantees to affect, disturb
or prejudice the rights of any other Holders, or to obtain or to seek to obtain priority or preference over any other Holders or to enforce
any right under this Indenture or the Guarantees, except in the manner herein provided and for the equal and ratable benefit of all the
Holders (it being further understood that the Trustee does not have an affirmative duty to ascertain whether or not such actions or forbearances
are unduly prejudicial to such Holders).

 

SECTION 508.        
Unconditional Right of Holders to Receive Principal, Premium and Interest. Notwithstanding any other provision in this Indenture,
the Holder shall have the right, which is absolute and unconditional, to receive payment, as provided herein (including, if applicable,
Article Eleven) and in such Note of the principal of (and premium, if any) and (subject to Section 307) interest on such Note on the respective
Stated Maturities expressed in such Note (or, in the case of redemption, on the Redemption Date) and to institute suit for the enforcement
of any such payment on or after such respective dates, and such rights shall not be impaired without the consent of such Holder.

 

SECTION 509.        
Restoration of Rights and Remedies. If the Trustee or any Holder has instituted any proceeding to enforce any right or remedy
under this Indenture or the Guarantees 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,
any other obligor of the Notes, 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 510.         Rights
and Remedies Cumulative. Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost
or stolen Notes in the last paragraph of Section 306, 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.

 

    -52-

     

    

 

SECTION 511.        
Delay or Omission Not Waiver. No delay or omission of the Trustee or of any Holder of any Note 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 Five 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.

 

SECTION 512.        
Control by Holders. The Holders of a majority in principal amount of the Outstanding Notes shall have the right to 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 with respect to the Notes; provided that:

 

(1)         
such direction shall not be in conflict with any rule of law or with this Indenture, and such Holders have complied with Section
603(f),

 

(2)         
the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction, and

 

(3)         
the Trustee need not take any action which might involve it in personal liability or be unduly prejudicial to the Holders not consenting
(it being understood that the Trustee does not have an affirmative duty to ascertain whether or not such actions or inactions are unduly
prejudicial to such Holders).

 

SECTION 513.        
Waiver of Past Defaults. Subject to Sections 508 and 902, the Holders of not less than a majority in principal amount of
the Outstanding Notes by written notice to the Trustee may on behalf of the Holders of all such Notes waive any existing Default or Event
of Default and its consequences hereunder (except (1) a continuing Default or Event of Default in the payment of interest on, premium,
if any, or the principal of any such Note held by a non-consenting Holder, or (2) in respect of a covenant or provision hereof or in any
Guarantee which under Article Nine cannot be modified or amended without the consent of the Holder of each Outstanding Note affected which
shall require the consent of all Holder of the Notes) and rescind any acceleration and its consequences with respect to the Notes; provided
such rescission would not conflict with any judgment of a court of competent jurisdiction.

 

Upon any such waiver, 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 Event of Default or impair any right consequent thereon.

 

SECTION 514.        
Waiver of Stay or Extension Laws. Each of the Issuer, the Guarantors and any other obligor on the Notes covenants (to the
extent that it may lawfully do so) that it will not 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 each of the Issuer, the Guarantors and any other obligor on the Notes (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not hinder, delay or impede
the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such
law had been enacted.

 

SECTION 515.        
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 a 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
attorney’s 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 515 does not apply to a suit by the Trustee, a suit by a Holder relating to right
to payment hereof, or a suit by Holders of more than 10% in principal amount of the then Outstanding Notes.

THE TRUSTEE

 

SECTION 601.        
Duties of the Trustee.

 

(a)           
Except during the continuance of an Event of Default,

 

(1)         
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

 

(2)         
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;
but in the case of any such certificates or opinions specifically required by any provision hereof to be provided to it, the Trustee shall
be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture, but not to verify
the contents thereof.

 

(b)           
If an Event of Default has occurred and is continuing of which a Responsible Officer has actual knowledge or of which written notice
of such Event of Default shall have been given to a Responsible Officer by the Issuer, any other obligor of the Notes or by Holders of
at least 25% of the aggregate principal amount of the Notes, the Trustee shall exercise such of the rights and powers vested in it by
this Indenture, and use the same degree of care and skill in their exercise, as a prudent Person would exercise or use under the circumstances
in the conduct of such Person’s own affairs.

 

(c)           
No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent
failure to act, or its own willful misconduct, except that

 

(1)         
this clause (c) shall not be construed to limit the effect of clause (a) of this Section 601;

 

(2)         
the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it shall be proved
in a court of competent jurisdiction that the Trustee was negligent in ascertaining the pertinent facts; and

 

(3)         
the Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith in accordance with
the direction of the Holders of a majority in aggregate principal amount of the Outstanding Notes relating to the time, method and place
of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under
this Indenture;

 

(d)

SECTION 604.        
Trustee Not Responsible for Recitals or Issuance of Notes. The recitals contained herein and in the Notes, except for the
Trustee’s certificates of authentication, shall be taken as the statements of the Issuer, and neither the Trustee nor any Agent
assumes responsibility for their correctness. Neither the Trustee nor any Agent makes representations as to the validity or sufficiency

its individual or any other capacity, may become the owner or pledgee of Notes and, subject to TIA Sections 310(b) and 311, may otherwise
deal with the Issuer with the same rights it would have if it were not the Trustee, Paying Agent, Note Registrar or such other agent;
provided that if it acquires any “conflicting interest” (within the meaning of TIA Section 310(b)), it must eliminate
such conflict within 90 days, apply to the SEC for permission to continue or resign.

 

SECTION 606.

SECTION 607.

(1)               
to pay to the Trustee from time to time such compensation as shall be agreed in writing between the Issuer and the Trustee for

as otherwise expressly provided herein, to reimburse the Trustee upon its request for all reasonable expenses, disbursements and

and the expenses and disbursements of its agents and counsel), except any such expense, disbursement or advance as shall be
determined to have been caused by its own negligence or willful misconduct; and

 

    -56-

     

    

 

(3)               
 to indemnify the Trustee and any predecessor Trustee for, and to hold it harmless against, any and all loss, liability, claim,
damage or expense, including taxes (other than the taxes based on the income of the Trustee) incurred without negligence or willful misconduct
on its part arising out of or in connection with the acceptance or administration of this trust, including the reasonable costs and expenses
of defending itself against any claim regardless of whether the claim is asserted by the Issuer, a Guarantor, a Holder or any other Person
or liability in connection with the exercise or performance of any of its powers or duties hereunder, including the reasonable costs and
expenses of enforcing this Indenture or a Guarantee against the Issuer or a Guarantor (including this Section 607).

 

The Trustee shall notify the Issuer promptly of
any claim asserted against the Trustee or any of its agents for which it may seek indemnity. Failure to provide such notice shall not
relieve the Issuer of its obligations in this Section 607 unless the failure to notify the Issuer impairs the Issuer’s ability to
defend such claim. The Issuer may, at the request of the Trustee, defend the claim and the Trustee shall cooperate in the defense; provided
that the Trustee and its agents subject to the claim may have separate counsel and the Issuer 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 the Issuer assumes
the Trustee’s defense and there is no conflict of interest between the Issuer and the Trustee and its agents subject to the claim
in connection with such defenses, as reasonably determined by the Trustee. The Issuer need not pay for any settlement made without its
written consent.

 

The obligations of the Issuer and the Guarantors
under this Section 607 to compensate the Trustee, to pay or reimburse the Trustee for expenses, disbursements and advances and to indemnify
and hold harmless the Trustee shall constitute additional indebtedness hereunder and shall survive the satisfaction and discharge of this
Indenture and resignation or removal of the Trustee. As security for the performance of such obligations of the Issuer, the Trustee shall
have a claim prior to the Notes upon all property and funds held or collected by the Trustee as such, except funds held in trust solely
for the benefit of the Holders entitled thereto for the payment of principal of (and premium, if any) or interest on particular Notes.

 

When the Trustee incurs expenses or renders services
in connection with an Event of Default specified in Section 501(6), the expenses (including the reasonable charges and expenses of its
counsel) of and the compensation for such services are intended to constitute expenses of administration under any applicable Bankruptcy
Law. “Trustee” for the purposes of this Section 607 shall include any predecessor Trustee and the Trustee in each of its capacities
hereunder and each agent, custodian and other Person employed to act hereunder as permitted by this Indenture; provided, however,
that the negligence or willful misconduct of any predecessor Trustee hereunder shall not affect the rights of any other successor Trustee
hereunder (other than a successor Trustee that is successor by merger or consolidation to such predecessor Trustee).

 

The provisions of this Section 607 shall survive
the satisfaction and discharge of this Indenture and resignation or removal of the Trustee.

Corporate Trustee Required; Eligibility. There shall be at all times a Trustee hereunder which shall be eligible to act

reports of condition at least annually, pursuant to law or to the requirements of federal, State, territorial or District of Columbia
supervising or examining authority, then for the purposes of this Section 608, the combined capital and surplus of such corporation shall
be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the
Trustee shall cease to be eligible in accordance with the provisions of this Section 607, it shall resign immediately in the manner and
with the effect hereinafter specified in this Article Six.

the Issuer shall promptly appoint a successor trustee by written instrument, a copy of which shall be delivered to the resigning
Trustee and a copy to the successor Trustee. If the instrument of acceptance by a successor Trustee required by Section 610 shall not
have been delivered to the Trustee within 30 days after the giving of such notice of resignation, the resigning Trustee may petition,
at the expense of the Issuer, any court of competent jurisdiction for the appointment of a successor Trustee.

the Issuer are outstanding if the requirements for such exclusion set forth in TIA Section 310(b)(1) are met.

 

(e)               
The Trustee shall comply with TIA Section 311(a), excluding any creditor relationship listed in TIA Section 311(b). A Trustee who
has resigned or been removed shall be subject to TIA Section 311(a) to the extent indicated.

 

(f)                
If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for
any cause, the Issuer shall promptly appoint a successor Trustee. If, within one year after such resignation, removal or incapability,
or the occurrence of such vacancy, a successor Trustee shall be appointed by the Act of the Holders of a majority in principal amount
of the Outstanding Notes delivered to the Issuer and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its
acceptance of such appointment, become the successor Trustee and supersede the successor Trustee appointed by the Issuer. If no successor
Trustee shall have been so appointed by the Issuer or the Holders and accepted appointment in the manner hereinafter provided, any Holder
who has been a bona fide Holder for at least six months may, on behalf of himself and all others similarly situated, petition any court
of competent jurisdiction for the appointment of a successor Trustee.

instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such
successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of
the retiring Trustee; but, on request of the Issuer or the successor Trustee, such retiring Trustee shall, upon payment of its charges,
execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and
shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder. Upon
request of any such successor Trustee, the Issuer shall execute any and all instruments for more fully and certainly vesting in and confirming
to such successor Trustee all such rights, powers and trusts.

 

(b)               
No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified
and eligible under this Article Six.

 

SECTION 611.        
Merger, Conversion, Consolidation or Succession to Business. Any corporation into which the Trustee may be merged or converted
or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee
shall be a party, or any corporation succeeding to all or substantially all of the corporate trust business of the Trustee, shall be
the successor of the Trustee hereunder; provided such corporation shall be otherwise qualified and eligible under this Article
Six, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Notes
shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation
to such authenticating Trustee may adopt such authentication and deliver the Notes so authenticated with the same effect as if such successor
Trustee had itself authenticated such Notes. In case at that time any of the Notes shall not have been authenticated, any successor Trustee
may authenticate such Notes either in the name of any predecessor hereunder or in the name of the successor Trustee. In all such cases
such certificates shall have the full force and effect which this Indenture provides for the certificate of authentication of the Trustee
shall have; provided that, the right to adopt the certificate of authentication of any predecessor Trustee or to authenticate
Notes in the name of any predecessor Trustee shall apply only to its successor or successors by merger, conversion or consolidation.

SECTION 612.        
Appointment of Authenticating Agent. At any time when any of the Notes remain Outstanding, the Trustee may appoint one or
more agents (each an “Authenticating Agent”) with respect to the Notes which shall be authorized to act on behalf of
the Trustee to authenticate Notes and the Trustee shall give written notice of such appointment to all Holders of Notes with respect to
which such Authenticating Agent will serve, in the manner provided for in Section 107. Notes so authenticated shall be entitled to the
benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Any such appointment
shall be evidenced by an instrument in writing signed by an authorized signatory of the Trustee, and a copy of such instrument shall be
promptly furnished to the Issuer. Wherever reference is made in this Indenture to the authentication and delivery of Notes by the Trustee
or the Trustee’s certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf
of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent.
Each Authenticating Agent shall be acceptable to the Issuer.

 

Any corporation into which an Authenticating Agent
may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation
to which such Authenticating Agent shall be a party, or any corporation succeeding to all or substantially all the corporate agency or
corporate trust business of an Authenticating Agent, shall continue to be an Authenticating Agent; provided such corporation shall
be otherwise eligible under this Section 612, without the execution or filing of any paper or any further act on the part of the Trustee
or the Authenticating Agent.

 

An Authenticating Agent may resign at any time
by giving written notice thereof to the Trustee and to the Issuer. The Trustee may at any time terminate the agency of an Authenticating
Agent by giving written notice thereof to such Authenticating Agent and to the Issuer. Upon receiving such a notice of resignation or
upon such a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions
of this Section 612, the Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Issuer and shall give written
notice of such appointment to all Holders of Notes, in the manner provided for in Section 107. Any successor Authenticating Agent upon
acceptance of its appointment hereunder shall become vested with all the rights, powers and duties of its predecessor hereunder, with
like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under
the provisions of this Section 612.

 

The Issuer agrees to pay to each Authenticating
Agent from time to time such compensation for its services under this Section 612 as shall be agreed in writing between the Issuer and
such Authenticating Agent.

 

If an appointment is made pursuant to this Section
612, the Notes may have endorsed thereon, in addition to the Trustee’s certificate of authentication, an alternate certificate of
authentication in the following form:

 

This is one of the Notes designated therein referred
to in the within-mentioned Indenture.

Subject to Section 1208, the Successor Person or
the Division Successor(s), as applicable, shall succeed to, and be substituted for, such Guarantor under this Indenture and such Guarantor’s
Guarantee and such Guarantor will automatically be released and discharged from its obligations under this Indenture and such Guarantor’s
Guarantee. Notwithstanding the foregoing, any Guarantor may (i) merge into or transfer all or part of its properties and assets (including

exercise every right and power of, the Issuer or such Guarantor, as the case may be, under this Indenture or the Guarantees, as the case
may be, with the same effect as if such successor Person had been named as the Issuer or such Guarantor, as the case may be, herein or
the Guarantees, as the case may be. When a successor Person assumes all obligations of its predecessor hereunder, the Notes or the Guarantees,
as the case may be, such predecessor shall be released from all obligations; provided that in the event of a transfer or lease,
the predecessor shall not be released from the payment of principal and interest or other obligations on the Notes or the Guarantees,
as the case may be.

COVENANTS

 

SECTION 1001.     
Payment of Principal, Premium, if any, and Interest. The Issuer covenants and agrees for the benefit of the Holders that
it will duly and punctually pay the principal of (and premium on, if any) the Notes in accordance with the terms of the Notes and this
Indenture.

 

The Issuer shall pay interest on overdue principal
at the rate specified therefor in the Notes, and it shall pay interest on overdue installments of interest at the same rate to the extent
lawful.

 

SECTION 1002.     
Maintenance of Office or Agency. The Issuer will maintain in The City of New York, an office or agency where Notes may be
presented or surrendered for payment, where Notes may be surrendered for registration of transfer or exchange and where notices and demands
to or upon the Issuer in respect of the Notes and this Indenture may be served. The designated office of the Trustee shall be such office
or agency of the Issuer in The City of New York, unless the Issuer shall designate and maintain some other office or agency for one or
more of such purposes. The Issuer will give prompt written notice to the Trustee of 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, and the
Issuer hereby appoints the Trustee as its agent to receive all such presentations, surrenders, notices and demands.

 

The Issuer may also from time to time designate
one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to
time rescind any such designation; provided, that no such designation or rescission shall in any manner relieve the Issuer of its
obligation to maintain an office or agency in The City of New York. The Issuer will give prompt written notice to the Trustee of any such
designation or rescission and any change in the location of any such other office or agency.

 

SECTION 1003.     
Money for Notes Payments to Be Held in Trust. If the Issuer shall at any time act as its own Paying Agent, it will, on or
before each due date of the principal of (or premium, if any) on any of the Notes, segregate and hold in trust for the benefit of the
Persons entitled thereto a sum sufficient to pay the principal of (or premium, if any) or interest so becoming due until such sums shall
be paid to such Persons or otherwise disposed of as herein provided and will promptly notify the Trustee of its action or failure so to
act.

 

Whenever the Issuer shall have one or more Paying
Agents for the Notes, it will, on or before each due date of the principal of (or premium, if any) or interest on any Notes in accordance
with Section 1001, deposit with a Paying Agent a sum sufficient to pay the principal (and premium, if any) or interest so becoming due,
such sum to be held in trust for the benefit of the Persons entitled to such principal, premium or interest, and (unless such Paying Agent
is the Trustee) the Issuer will promptly notify the Trustee in writing of such action or any failure so to act.

 

Each Paying Agent agrees:

 

(1)               
that it will hold all sums received by it as Paying Agent for the payment of the principal of or interest on any Notes in trust
for the benefit of the Holders or of the Trustee;

 

(2)               
that it will give the Trustee notice of any failure by the Issuer to make any payment of the principal of or interest on any Notes
and any other payments to be made by or on behalf of the Issuer under this Indenture or the Notes when the same shall be due and payable;
and

 

(3)               
that it will pay any such sums so held in trust by it to the Trustee forthwith upon the Trustee’s written request at any
time during the continuance of the failure referred to in clause (2) above.

 

The Issuer may at any time, for the purpose
of obtaining the satisfaction and discharge of this Indenture or for any other purpose, pay, or by Issuer Order direct any Paying
Agent to pay, to the Trustee all sums held in trust by the Issuer or such Paying Agent, such sums to be held by the Trustee upon the
same trusts as those upon which such sums were held by the Issuer or such Paying Agent; and, upon such payment by any Paying Agent
to the Trustee, such Paying Agent shall be released from all further liability with respect to such sums.

 

    -65-

     

    

 

Any money deposited with the Trustee or any Paying
Agent, or then held by the Issuer, in trust for the payment of the principal of (or premium, if any) or interest on any Note and remaining
unclaimed for two years after such principal, premium or interest has become due and payable shall be paid to the Issuer on Issuer Request,
or (if then held by the Issuer) shall be discharged from such trust; and the Holder of such Note shall thereafter, as an unsecured general
creditor, look only to the Issuer for payment thereof, and all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Issuer as Trustee thereof, shall thereupon cease; provided, that the Trustee or such Paying Agent,
before being required to make any such repayment, may at the expense of the Issuer cause to be published once, in a newspaper published
in the English language, customarily published on each Business Day and of general circulation in the Borough of Manhattan, The City of
New York, notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from

(a)                
The Issuer will deliver to the Trustee within 120 days after the end of each fiscal year, an Officer’s Certificate stating
that a review of the activities of the Issuer and its Restricted Subsidiaries during the preceding fiscal year has been made under the
supervision of the signing officer with a view to determining whether it has kept, observed, performed and fulfilled, and has caused each
of its Restricted Subsidiaries to keep, observe, perform and fulfill its obligations under this Indenture and further stating that, to
the best of his or her knowledge, the Issuer during such preceding fiscal year has kept, observed, performed and fulfilled, and has caused
each of its Restricted Subsidiaries to keep, observe, perform and fulfill each and every such covenant contained in this Indenture and
no Default or Event of Default occurred during such year and at the date of such certificate there is no Default or Event of Default which
has occurred and is continuing or, if such signers do know of such Default or Event of Default, the certificate shall describe its status,
with particularity and that, to the best of his or her knowledge, no event has occurred and remains by reason of which payments on the
account of the principal of or interest, if any, on the Notes is prohibited or if such event has occurred, a description of the event
and what action each is taking or proposes to take with respect thereto. The Officer’s Certificate shall also notify the Trustee
should the Issuer elect to change the manner in which it fixes its fiscal year end. For purposes of this Section 1008(a), such compliance
shall be determined without regard to any period of grace or requirement of notice under this Indenture.

 

(b)               
When any Default or Event of Default has occurred and is continuing under this Indenture, the Issuer shall deliver to the Trustee
an Officer’s Certificate specifying such event, notice or other action within ten Business Days of becoming aware of such occurrence.

 

SECTION 1009.     
Reports and Other Information.

 

(a)                
Whether or not the Issuer is subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, so long as any Notes
are outstanding, the Issuer will furnish to the Holder, within fifteen (15) Business Days after filing, or in the event no such filing
is required, within fifteen (15) Business Days after the end of the time periods specified in those sections and any extension period
granted under Section 12b-25 of the Exchange Act:

 

(1)                (x)
all annual and quarterly financial statements that would be required to be contained in a filing with the SEC on Forms 10-K and 10-Q
(or any successor or comparable forms) of the Issuer, if the Issuer were required to file such forms, plus a
 “Management’s Discussion and Analysis of Financial Condition and Results of Operations” section; and (y) with
respect to the annual financial statements only, a report on the annual financial statements by the Issuer’s independent
registered public accounting firm; and

 

(2)               
all information that would be required to be contained in filings with the SEC on Form 8-K under Items 1.01 (including furnishing
any material debt agreements that would be required to be described in such Form 8-K), 1.02, 1.03, 2.01, 2.05, 2.06, 4.01, 4.02, 5.01
and 5.02(b) and (c) (other than with respect to information otherwise required or contemplated by Item 402 of Regulation S-K) as in effect
on the Issue Date if the Issuer were required to file such reports; provided, however, that no such current report shall
be required to include as an exhibit, or to include a summary of the terms of, any employment or compensatory arrangement agreement, plan
or understanding between the Issuer (or any of its Subsidiaries) and any director, manager or executive officer, of the Issuer (or any
of its Subsidiaries).

 

The Issuer shall make available such information
and such reports (as well as the details regarding the conference call described below) to the Trustee under this Indenture, to any Holder
and, upon request, to any beneficial owner of the Notes, in each case, by (a) filing such reports with the SEC (and such reports are publicly
available) or (b) posting such reports on the Issuer’s website and issuing a press release in respect thereof. The Issuer will hold
a quarterly conference call for all Holders and securities analysts (to the extent providing analysis of investment in the Notes) to discuss
such financial information (including a customary Q&A session) no later than five (5) Business Days after distribution of such financial
information.

(b)               
The Issuer shall provide S&P and Moody’s (and their respective successors) with information on a periodic basis as S&P
or Moody’s, as the case may be, shall reasonably require in order to maintain public ratings of the Notes. To the extent not satisfied
by the foregoing, the Issuer shall also furnish to Holders, securities analysts (to the extent providing analysis of investment in the
Notes) and prospective investors in the Notes upon request the information required to be delivered pursuant to Rule 144A(d)(4) under
the Securities Act, so long as the Notes are not freely transferable under the Securities Act.

 

(c)                
If the Issuer 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 the Issuer, then the annual
and quarterly information required by clause (1) of the first paragraph of this covenant shall include a reasonably detailed presentation,
either on the face of the financial statements or in the footnotes thereto, of the financial condition and results of operations of the
Issuer and its Restricted Subsidiaries separate from the financial condition and results of operations of such Unrestricted Subsidiaries.

 

(d)               
Notwithstanding the foregoing, the financial statements, information and other documents required to be provided as described above,
may be those of (i) the Issuer or (ii) any direct or indirect parent of the Issuer rather than those of the Issuer; provided that
the same is accompanied by consolidating information that explains in reasonable detail the differences between the information relating
to such parent, on the one hand, and the information relating to the Issuer and the Restricted Subsidiaries on a standalone basis, on
the other hand.

 

Delivery of reports, information and documents
to the Trustee is for informational purposes only and its receipt of such reports shall not constitute constructive notice of any information
contained therein or determinable from information contained therein, including our compliance with any of our covenants under this Indenture
or the Notes (as to which the Trustee is entitled to rely exclusively on Officer’s Certificates).

 

The Trustee shall not be obligated to monitor or
confirm, on a continuing basis or otherwise, our compliance with the covenants or with respect to this Indenture or any reports or other
documents filed with the SEC under this Indenture.

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 another currency 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, in the case of revolving credit debt; provided that if such Indebtedness is incurred
to Refinance other Indebtedness denominated in another currency, 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
(i) the principal amount of such Indebtedness being Refinanced plus (ii) the aggregate amount of fees, underwriting discounts,
premiums and other costs and expenses incurred in connection with such Refinancing.

 

(d)               
This Indenture shall not treat (1) unsecured Indebtedness as subordinated or junior to Secured Indebtedness merely because it is
unsecured or (2) Senior Indebtedness as subordinated or junior to any other Senior Indebtedness merely because it has a junior priority
with respect to the same collateral.

of the Issuer or any Guarantor, or any income or profits therefrom, or assign or convey any right to receive income therefrom, unless
the Notes (or the related Guarantee in the case of Liens of a Guarantor) are equally and ratably secured with (or, in the event the Lien
relates to Subordinated Indebtedness, are secured on a senior basis to) the obligations so secured. Any Lien created for the benefit of
the Holders of the Notes pursuant to this Section 1012 will provide by its terms that such Lien shall be automatically and unconditionally
released and discharged upon the release and discharge of the Lien that gave rise to the obligation to secure the Notes.

(2)               
the purchase price and the purchase date, which shall be no earlier than 15 days nor later than 60 days from the date such notice
is mailed (the “Change of Control Payment Date”);

 

(3)               
that any Note not properly tendered shall remain outstanding and continue to accrue interest;

 

(4)               
that, unless the Issuer defaults in the payment of the Change of Control Payment, all Notes accepted for payment pursuant to the
Change of Control Offer shall cease to accrue interest on the Change of Control Payment Date;

 

(5)               
that Holders electing to have any Notes purchased pursuant to a Change of Control Offer shall be required to surrender such Notes,
with the form entitled “Option of Holder to Elect Purchase” on the reverse of such Notes completed, to the Paying Agent specified
in the notice at the address specified in the notice prior to the close of business on the 3rd (third) Business Day preceding the Change
of Control Payment Date;

 

(6)               
that Holders shall be entitled to withdraw their tendered Notes and their election to require the Issuer to purchase such Notes;
provided that the Paying Agent receives, not later than the expiration time of the Change of Control Offer, electronic transmission
(in PDF), facsimile transmission or letter (sent in the same manner provided in the Change of Control Offer) setting forth the name of
the Holder of the Notes, the principal amount of Notes tendered for purchase, and a statement that such Holder is withdrawing its tendered
Notes and its election to have such Notes purchased;

 

(7)               
that if the Issuer is purchasing less than all of the Notes held by any Holder, the Holder will be issued new Notes and such new
Notes will be equal in principal amount to the unpurchased portion of the Notes surrendered. The unpurchased portion of the Notes must
be equal to $2,000 or an integral multiple of $1,000 in excess thereof;

 

(8)               
if such notice is delivered prior to the occurrence of a Change of Control, stating that the Change of Control Offer is conditional
on the occurrence of such Change of Control and if applicable, shall state that, in the Issuer’s discretion, the Change of Control
Payment Date may be delayed until such time as the Change of Control shall occur, or that such redemption may not occur and such notice
may be rescinded in the event that the Issuer shall determine that such condition will not be satisfied by the Change of Control Payment
Date, or by the Change of Control Payment as so delayed; and

 

(9)               
the other instructions, as determined by us, consistent with this Section 1016, that a Holder must follow.

 

(b)               
While the Notes are in global form and the Issuer makes an offer to purchase all of the Notes pursuant to the Change of Control
Offer, a Holder may exercise its option to elect for the purchase of the Notes through the facilities of the Depository, subject to its
rules and regulations.

 

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

 

(d)               
On the Change of Control Payment Date, the Issuer shall, to the extent permitted by law,

 

(1)               
 accept for payment all Notes issued by it or portions thereof properly tendered pursuant to the Change of Control Offer,

 

(2)               
unless deposited before the Change of Control Payment Date, deposit with the Paying Agent an amount equal to the aggregate Change
of Control Payment in respect of all Notes or portions thereof so tendered, and

 

(3)               
deliver, or cause to be delivered, to the Trustee for cancellation the Notes so accepted together with an Officer’s Certificate
stating that all Notes or portions thereof have been tendered to and purchased by the Issuer.

 

    -84-

     

    

 

(e)                In
the event that the Issuer makes a Change of Control Payment, the Paying Agent shall promptly deliver or mail to each Holder of the Notes
the Change of Control Payment received by the Paying Agent for such Notes, and upon receipt of written direction from the Issuer, the
Trustee shall promptly authenticate a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any;
provided that each such new Note shall be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof.
The Issuer shall publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control
Payment Date.

 

(f)                 The
Issuer shall not be required to make a Change of Control Offer following a Change of Control if (i) a third party makes the Change of
Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture applicable to
a Change of Control Offer made by the Issuer and purchases all such Notes validly tendered and not withdrawn under such Change of Control
Offer or (ii) a notice of redemption has been given pursuant to Section 1105. Notwithstanding anything to the contrary herein, a Change
of Control Offer may be made in advance of a Change of Control, conditional upon such Change of Control, if a definitive agreement is
in place for the Change of Control at the time of the making of such Change of Control Offer.

 

(g)               
If Holders of not less than 90% in aggregate principal amount of the outstanding Notes validly tender and do not withdraw such
Notes in a Change of Control Offer and the Issuer, or any third party making a Change of Control Offer in lieu of the Issuer as described
above, purchases all of the Notes validly tendered and not withdrawn by such Holders, the Issuer or such third party will have the right,
upon not less than 15 days nor more than 60 days’ prior notice, provided that such notice is given not more than 30 days
following such purchase pursuant to the Change of Control Offer described above, to redeem all Notes that remain outstanding following
such purchase on a specified date (the “Second Change of Control Payment Date”) at a price in cash equal to the applicable
Change of Control Payment in respect of the Second Change of Control Payment Date.

 

(h)               
The provisions of this Section 1016, including the definition of “Change of Control,” may be waived or modified with
the written consent of the Holders of a majority in principal amount of the Notes.

 

SECTION 1017.     
Asset Sales.

 

(a)               
The Issuer shall not, and shall not permit any Restricted Subsidiary to consummate, directly or indirectly, an Asset Sale, unless:

 

(1)               
the Issuer or such Restricted Subsidiary, as the case may be, receives consideration at the time of such Asset Sale at least equal
to the Fair Market Value (as determined at the time of contractually agreeing to such Asset Sale) of the assets sold or otherwise disposed
of; and

 

    -85-

     

    

 

(2)               
except in the case of a Permitted Asset Swap, at least 75% of the consideration from such Asset Sale and all other Asset Sales
since May 24, 2018, on a cumulative basis received by the Issuer or such Restricted Subsidiary, as the case may be, is in the form of
cash or Cash Equivalents; provided that the amount of:

 

(A)               any
liabilities (as reflected on the Issuer’s most recent consolidated balance sheet or in the footnotes thereto, or if incurred
or accrued subsequent to the date of such balance sheet, such liabilities that would have been reflected on the Issuer’s
consolidated balance sheet or in the footnotes thereto if such incurrence or accrual had taken place on or prior to the date of such
balance sheet, as determined in good faith by the Issuer) of the Issuer, other than liabilities that are by their terms subordinated
to the Notes, that are assumed by the transferee of any such assets (or are otherwise extinguished in connection with the
transactions relating to such Asset Sale) and for which the Issuer and all such Restricted Subsidiaries have been validly released
by all applicable creditors in writing,

 

    -85- 

     

    

 

(B)              
any securities, notes or other obligations or assets received by the Issuer or such Restricted Subsidiary from such transferee
that are converted by the Issuer or such Restricted Subsidiary into cash or Cash Equivalents, or by their terms are required to be satisfied
for cash or Cash Equivalents (to the extent of the cash or Cash Equivalents received), in each case, within 180 days following the closing
of such Asset Sale; and

 

(C)               any
Designated Non-cash Consideration received by the Issuer or such Restricted Subsidiary in such Asset Sale having an aggregate Fair
Market Value, taken together with all other Designated Non-cash Consideration received pursuant to this clause (C) that is at that
time outstanding, not to exceed the greater of (x) $100.0 million and (y) 25% of EBITDA for the Applicable Measurement Period 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, shall be deemed to be
cash for purposes of this provision and for no other purpose.

 

    -86- 

     

    

 

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

 

(1)               
to permanently repay or reduce:

 

(A)              
Secured Indebtedness under Credit Facilities to the extent such Indebtedness was incurred under Section 1011(b)(1), and to correspondingly
reduce any outstanding commitments with respect thereto;

 

(B)              
Obligations under Senior Secured Indebtedness of the Issuer or a Guarantor, and to correspondingly reduce any outstanding commitments
with respect thereto;

 

(C)              
Obligations under the Notes or any other Senior Indebtedness of the Issuer or any Restricted Subsidiary (and, in the case of other
Senior Indebtedness, to correspondingly reduce any outstanding commitments with respect thereto, if applicable); provided that
if the Issuer or any Restricted Subsidiary shall so repay any such Senior Indebtedness other than the Notes, the Issuer or such Restricted
Subsidiary shall reduce Obligations under the Notes on a pro rata basis by, at its option, either (A) redeeming Notes as described
under Section 1101 or (B) purchasing Notes through open market purchases, at a price equal to or higher than 100% of the principal amount
thereof, in a manner that complies with this Indenture and applicable securities law or make an offer (in accordance with the procedures
set forth below for an Asset Sale Offer) to all Holders to purchase their Notes on a ratable basis with such other Senior Indebtedness
for no less than 100% of the principal amount thereof, plus the amount of accrued but unpaid interest, if any, thereon up to the
principal amount of Notes to be repurchased; or

 

(D)              
Indebtedness of a Restricted Subsidiary that is not a Guarantor, other than Indebtedness owed to the Issuer or another Restricted
Subsidiary;

 

    -87- 

     

    

 

(2)                to
make (a) an Investment in any one or more businesses; provided that such Investment in any business is in the form of the
acquisition of Capital Stock and results in the Issuer or a Restricted Subsidiary, as the case may be, owning an amount of the
Capital Stock of such business such that it constitutes or continues to constitute a Restricted Subsidiary, (b) capital expenditures
or (c) acquisitions of other property or assets, in the case of each of clauses (a), (b) and (c), either (i) used or useful in a
Similar Business or (ii) that replace the businesses, properties and/or assets that are the subject of such Asset Sale; provided that
the Issuer and its Restricted Subsidiaries shall be deemed to have complied with this clause (2) if and to the extent that, within
450 days after the Asset Sale that generated the Net Proceeds, the Issuer or such Restricted Subsidiary has entered into and not
abandoned or rejected a binding agreement to consummate any such investment described in this clause (2) with the good faith
expectation that such Net Proceeds will be applied to satisfy such commitment within 180 days of such commitment (an
 “Acceptable Commitment”) and, in the event any Acceptable Commitment is later cancelled or terminated for any
reason before the Net Proceeds are applied in connection therewith, the Issuer or such Restricted Subsidiary enters into another
Acceptable Commitment (a “Second Commitment”) within 180 days of such cancellation or termination; provided, further,
that if any Second Commitment is later cancelled or terminated for any reason before such Net Proceeds are applied, then such Net
Proceeds shall constitute Excess Proceeds; or

 

(3)               
any combination of the foregoing.

 

(c)                
Any Net Proceeds from any Asset Sale that are not invested or applied in accordance with Section 1017(b) within the time set forth
therein will be deemed to constitute “Excess Proceeds.” Within ten (10) Business Days after the date that the
aggregate amount of Excess Proceeds exceeds $25.0 million, the Issuer shall make an offer to all Holders of the Notes, and, if required
by the terms of any Indebtedness that is pari passu with the Notes (“Pari Passu Indebtedness”), to the holders
of such Pari Passu Indebtedness (an “Asset Sale Offer”), to purchase the maximum aggregate principal amount of Notes
and such Pari Passu Indebtedness, and with respect to the Notes only in denominations of $2,000 initial principal amount and multiples
of $1,000 thereafter, that may be purchased out of the Excess Proceeds at an offer price, in the case of the Notes, in cash in an amount
equal to 100% of the principal amount thereof, plus accrued and unpaid interest, if any, to the date fixed for the closing of such
offer, in accordance with the procedures set forth in this Indenture. In the event that the Issuer or a Restricted Subsidiary prepays
any Pari Passu Indebtedness that is outstanding under a revolving credit or other committed loan facility pursuant to an Asset Sale Offer,
the Issuer or such Restricted Subsidiary shall cause the related loan commitment to be reduced in an amount equal to the principal amount
so prepaid.

 

The Issuer shall commence an Asset Sale Offer by
transmitting electronically or by mailing the notice required pursuant to the terms of this Indenture, with a copy to the Trustee. To
the extent that the aggregate amount of Notes and, if applicable, Pari Passu Indebtedness tendered pursuant to an Asset Sale Offer is
less than the Excess Proceeds (or, in the case of an Asset Sale Offer being effected in advance of being required to do so by this Indenture,
the amount of Net Proceeds the Issuer is offering to apply in such Asset Sale Offer), the Issuer may use any remaining Excess Proceeds
(or such amount offered) in any manner not prohibited by this Indenture. If the aggregate principal amount of Notes and, if applicable,
Pari Passu Indebtedness surrendered in an Asset Sale Offer exceeds the amount of Excess Proceeds, the Trustee shall select the Notes to
be purchased or repaid on a pro rata basis and in accordance with the procedures of the Depository; provided that no Notes
of $2,000 or less shall be repurchased in part. Upon completion of any such Asset Sale Offer, the amount of Excess Proceeds shall be reset
at zero, and in the case of an Asset Sale Offer being effected in advance of being required to do so by this Indenture, the amount of
Net Proceeds the Issuer is offering to apply in such Asset Sale Offer shall be excluded in subsequent calculations of Excess Proceeds.

 

(d)               
Pending the final application of any Net Proceeds pursuant to this Section 1017, the Issuer or the applicable Restricted Subsidiary
may apply such Net Proceeds temporarily to reduce Indebtedness outstanding under a revolving credit facility or otherwise invest such
Net Proceeds in any manner not prohibited by this Indenture.

 

(e)                
The Issuer shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations
thereunder to the extent such laws or regulations are applicable in connection with the repurchase of the Notes 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
shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations described in
this Indenture by virtue thereof.

 

    -88- 

     

    

 

(f)                 
 The provisions under this Indenture relative to the Issuer’s obligation to make an offer to repurchase the Notes as a result
of an Asset Sale may be waived or modified with the written consent of the Holders of a majority in principal amount of the Notes.

 

(g)               
Notices of purchase or redemption shall be delivered electronically or mailed by first-class mail, postage prepaid, at least 15
but not more than 60 days before the purchase or Redemption Date to the Trustee and each Holder of Notes at such Holder’s registered
address or otherwise in accordance with the procedures of the Depository, except that redemption notices may be mailed more than 60 days
prior to a Redemption Date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of this
Indenture. If any Note is to be purchased or redeemed in part only, any notice of purchase or redemption that relates to such Note shall
state the portion of the principal amount thereof that has been or is to be purchased or redeemed.

 

(h)               
If any Notes are to be purchased or redeemed in part only, the Issuer shall issue a new Note in principal amount equal to the unredeemed
portion of the original Note in the name of the Holder thereof upon cancellation of the original Note. Notes called for redemption become
due on the date fixed for redemption, unless such redemption is conditioned on the happening of a future event. On and after the Redemption
Date, unless the Issuer defaults in payment of the Redemption Price, interest shall cease to accrue on Notes or portions thereof called
for redemption, unless such redemption is conditioned on the happening of a future event.

 

SECTION 1018.     
Suspension of Covenants.

 

(a)                
During any period of time that: (1) the Notes have Investment Grade Ratings from both Rating Agencies and (2) no Default or Event
of Default has occurred and is continuing under this Indenture (the occurrence of the events described in the foregoing clauses (1) and
(2) being collectively referred to as a “Covenant Suspension Event”), the Issuer and the Restricted Subsidiaries shall
not be subject to the following provisions of this Indenture:

 

(A)     
clause (a)(4) of Section 801;

 

(B)     Section 1010;

 

(C)     Section 1011;

 

(D)     Section 1013;

 

(E)     Section 1014;

 

(F)     Section 1015; and

 

(G)     Section 1017;

 

(collectively, the “Suspended Covenants”).
Upon the occurrence of a Covenant Suspension Event (the date of such occurrence, the “Suspension Date”), the
amount of Excess Proceeds from Net Proceeds shall be set at zero. In the event that the Issuer and the Restricted Subsidiaries are
not subject to the Suspended Covenants 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 withdraws its Investment Grade Rating or downgrades the
rating assigned to the Notes below an Investment Grade Rating, then the Issuer and the Restricted Subsidiaries will thereafter again
be subject to the Suspended Covenants with respect to future events. The period of time between the Suspension Date and the
Reversion Date is referred to in this description as the “Suspension Period.” Notwithstanding that the Suspended
Covenants may be reinstated, no Default, Event of Default or breach of any kind shall be deemed to exist under this Indenture, the
Notes or the Guarantees with respect to the Suspended Covenants, and none of the Issuer or any of its Subsidiaries shall bear any
liability for any actions taken or events occurring during the Suspension Period, or any actions taken at any time pursuant to any
contractual obligation arising prior to the Reversion Date, as a result of a failure to comply with the Suspended Covenants during
the Suspension Period (or upon termination of the Suspension Period or after that time based solely on events that occurred during
the Suspension Period). The Issuer shall provide an Officer’s Certificate to the Trustee indicating the occurrence of any
Suspension Date or Reversion Date. The Trustee shall have no obligation to independently determine or verify if such events have
occurred or notify the Holders of any Suspension Date or Reversion Date. The Trustee may provide a copy of such Officer’s
Certificate to any Holder upon request.

 

    -89- 

     

    

 

(b)               
On the Reversion Date, all Indebtedness incurred, or Disqualified Stock issued, during the Suspension Period shall be deemed to
have been outstanding on the Issue Date, so that they are classified to have been incurred or issued pursuant to Section 1011(b)(3). On
the Reversion Date, all Liens created, incurred or assumed during the Suspension Period in compliance with this Indenture will be deemed
to have been outstanding on the Issue Date, so that they are classified as permitted under clause (7) of the definition of “Permitted
Liens.” Calculations made after the Reversion Date of the amount available to be made as Restricted Payments under Section 1010
shall be made as though Section 1010 had been in effect since the Issue Date and throughout the Suspension Period, but with the actions
taken by the Issuer and its Restricted Subsidiaries during the Suspension Period having no effect on such calculation. No Subsidiaries
shall be designated as Unrestricted Subsidiaries during any Suspension Period. Any Affiliate Transaction entered into after the Reversion
Date pursuant to an agreement entered into during any Suspension Period shall be deemed to be permitted pursuant Section 1013(b)(6). Any
encumbrance or restriction on the ability of any Restricted Subsidiary that is not a Guarantor to take any action described in Sections
1014(a) through (c) that becomes effective during any Suspension Period shall be deemed to be permitted pursuant to Section 1014(c)(1).

 

SECTION 1019.     
Financial Calculations for Limited Condition Acquisitions.When calculating the availability under any basket or ratio
under this Indenture, in each case in connection with a Limited Condition Acquisition, the date of determination of such basket or ratio
and of any Default or Event of Default may, at the option of the Issuer, be the date the definitive agreements for such Limited Condition
Acquisition are entered into and such baskets or ratios shall be calculated with such pro forma adjustments as are appropriate
and consistent with the pro forma adjustment provisions set forth in the definition of “Fixed Charge Coverage Ratio”
after giving effect to such Limited Condition Acquisition and the other transactions to be entered into in connection therewith (including
any incurrence of Indebtedness and the use of proceeds thereof) as if they occurred at the beginning of the applicable period for purposes
of determining the ability to consummate any such Limited Condition Acquisition (and not for purposes of any subsequent availability of
any basket or ratio), and, for the avoidance of doubt, (x) if any of such baskets or ratios are exceeded as a result of fluctuations
in such basket or ratio (including due to fluctuations in EBITDA of the Issuer or the target company) subsequent to such date of determination
and at or prior to the consummation of the relevant Limited Condition Acquisition, such baskets or ratios will not be deemed to have been
exceeded as a result of such fluctuations solely for purposes of determining whether the Limited Condition Acquisition and related transactions
are permitted hereunder and (y) such baskets or ratios shall not be tested at the time of consummation of such Limited Condition
Acquisition or related transactions; provided, further, that if the Issuer elects to have such determinations occur at the
time of entry into such definitive agreement, any such transactions (including any incurrence of Indebtedness and the use of proceeds
thereof) shall be deemed to have occurred on the date the definitive agreements are entered into and outstanding thereafter for purposes
of calculating any baskets or ratios under this Indenture after the date of such agreement and before the consummation of such Limited
Condition Acquisition, unless and until such Limited Condition Acquisition has been abandoned or such definitive agreement has expired
or been terminated prior to consummation thereof.

under this Indenture after the Issue Date) remains outstanding immediately after the occurrence of each such redemption; provided,
further, that each such redemption occurs within 120 days of the date of closing of each such Equity Offering.

 

SECTION 1102.     
Applicability of Article. Redemption of Notes at the election of the Issuer or otherwise, as permitted or required by any
provision of this Indenture, shall be made in accordance with such provision and this Article Eleven.

 

SECTION 1103.     
Election to Redeem; Notice to Trustee. In case of any redemption at the election of the Issuer, the Issuer shall, at least
three Business Days before notice of redemption is required to be sent to Holders pursuant to Section 1105 hereof (unless a shorter notice
shall be satisfactory to the Trustee) but not more than 60 days before a Redemption Date, notify the Trustee of such Redemption Date and
of the principal amount of Notes to be redeemed and, if required, shall deliver to the Trustee such documentation and records as shall
enable the Trustee to select the Notes to be redeemed pursuant to Section 1104.

 

SECTION 1104.     
Selection by Trustee of Notes to Be Redeemed. With respect to any partial redemption or repurchase of Notes made pursuant
to this Indenture, if less than all of the Notes are to be redeemed at any given time, selection of such Notes for redemption will be

provided that no Notes of $2,000 or less shall be redeemed or repurchased in part.

 

Notices of purchase or redemption shall be delivered
electronically or mailed by first-class mail, postage prepaid, at least 15 but not more than 60 days before the purchase or Redemption
Date to the Trustee and each Holder at such Holder’s registered address or otherwise in accordance with the procedures of the Depository,

or redeemed in part only, any notice of purchase or redemption that relates to such Note shall state the portion of the principal amount
thereof that has been or is to be purchased or redeemed.

 

If any Notes are to be purchased or redeemed in
part only, the Issuer will issue a new Note in principal amount equal to the unredeemed portion of the original Note in the name of the
Holder thereof upon cancellation of the original Note. Notes called for redemption become due on the date fixed for redemption, unless
such redemption is conditioned on the happening of a future event. On and after the Redemption Date, unless the Issuer defaults in payment
of the Redemption Price, interest shall cease to accrue on Notes or portions thereof called for redemption, unless such redemption is
conditioned on the happening of a future event.

 

SECTION 1105.     
Notice of Redemption. Notice of redemption shall be given in the manner provided for in Section 107 not less than 15 nor
more than 60 days prior to the Redemption Date, to each Holder to be redeemed.

(4)               
in case any Note is to be redeemed in part only, the notice which relates to such Note shall state that on and after the Redemption
Date, upon surrender of such Note, the Holder will receive, without charge, a new Note or Notes of authorized denominations for the principal
amount thereof remaining unredeemed,

 

(5)               
that on the Redemption Date the Redemption Price (and accrued interest, if any, to the Redemption Date payable as provided in Section
1107) will become due and payable upon each such Note, or the portion thereof, to be redeemed, and that interest thereon will cease to
accrue on and after said date,

 

(6)               
any condition precedent to the redemption;

 

(7)               
the place or places where such Notes are to be surrendered for payment of the Redemption Price and accrued interest, if any,

 

(8)               
the name and address of the Paying Agent,

 

(9)               
that Notes called for redemption must be surrendered to the Paying Agent to collect the Redemption Price,

 

(10)            
CUSIP, ISIN or “Common Code” number and that no representation is made as to the accuracy or correctness of the CUSIP,
ISIN or “Common Code” number, if any, listed in such notice or printed on the Notes, and

 

(11)            
the paragraph of the Notes pursuant to which the Notes are to be redeemed.

 

Notice of redemption of Notes to be redeemed at
the election of the Issuer shall be given by the Issuer or, at the Issuer’s request and provision of such notice information two
Business Days (unless a shorter notice shall be agreed to by the Trustee) prior to the date notice is to be given, by the Trustee in the
name and at the expense of the Issuer.

 

Any redemption may, at the Issuer’s discretion,
be subject to one or more conditions precedent, which shall be set forth in the related notice of redemption, including, but not limited
to, completion of an Equity Offering, other offering or other transaction or event. In addition, if such redemption or purchase is subject
to satisfaction of one or more conditions precedent, such notice shall describe each such condition, and if applicable, shall state that,
in the Issuer’s discretion, the Redemption Date may be delayed until such time as any or all such conditions shall be satisfied,
or such redemption or purchase may not occur and such notice may be rescinded in the event that any or all such conditions shall not have
been satisfied by the Redemption Date, or by the Redemption Date as so delayed.

 

If any such condition precedent has not been satisfied
prior to the Redemption Date, the Issuer shall provide prompt notice to the Trustee. Upon receipt of such notice, the notice of redemption
shall either be rescinded and the redemption of the Notes shall not occur or the Redemption Date shall be delayed. Upon receipt, the Trustee
shall provide such notice to each Holder of the Notes in the same manner in which the notice of redemption was given.

 

    -92- 

     

    

 

The Issuer and its Affiliates may acquire the Notes

or otherwise.

 

SECTION 1106.     
Deposit of Redemption Price. Prior to any Redemption Date, the Issuer shall deposit with the Trustee or with a Paying Agent
(or, if the Issuer is acting as its own Paying Agent, segregate and hold in trust as provided in Section 1003) an amount of money sufficient
to pay the Redemption Price of, and accrued interest on, all the Notes which are to be redeemed on that date.

 

SECTION 1107.     
Notes Payable on Redemption Date. Notice of redemption having been given as aforesaid, the Notes to be redeemed shall, on
the Redemption Date, become due and payable, unless such redemption is conditioned on the happening of a future event, at the Redemption
Price therein specified (together with accrued interest to the Redemption Date), and from and after such date (unless the Issuer shall
default in the payment of the Redemption Price and accrued interest) such Notes shall cease to bear interest. Upon surrender of any such
Note for redemption in accordance with said notice, such Note shall be paid by the Issuer at the Redemption Price, together with accrued
interest to the Redemption Date and such Notes shall be cancelled by the Trustee; provided, that installments of interest whose
Stated Maturity is on or prior to the Redemption Date shall be payable to the Holders of such Notes, or one or more Predecessor Notes,

If any Note called for redemption shall not be
so paid upon surrender thereof for redemption, the principal (and premium, if any) shall, until paid, bear interest from the Redemption
Date at the rate borne by the Notes, unless such redemption is conditioned on the happening of a future event.

 

SECTION 1108.     
Notes Redeemed in Part. Any Note which is to be redeemed only in part (pursuant to the provisions of this Article Eleven)
shall be surrendered at an office or agency of the Issuer maintained for such purpose pursuant to Section 1002 (with, if the Issuer or
the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Issuer and the Trustee duly
executed by, the Holder thereof or such Holder’s attorney duly authorized in writing), and the Issuer shall execute, and the Trustee
shall authenticate and deliver to the Holder of such Note without service charge, a new Note or Notes, of any authorized denomination
as requested by such Holder, in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the
Note so surrendered.

GUARANTEES

 

SECTION 1201.     
Guarantees. The Notes will be guaranteed, on a full, joint and several basis, by the Issuer’s present and future domestic
Wholly-Owned Subsidiaries that are obligors under the Senior Credit Facility. Subject to this Article Twelve, each Guarantor, as primary
obligors and not merely as sureties, hereby jointly and severally, unconditionally and irrevocably guarantees, on a senior unsecured basis,
the Notes and obligations of the Issuer hereunder and thereunder, and guarantees to each Holder authenticated and delivered by the Trustee,
and to the Trustee for itself and on behalf of such Holder, that: (1) the principal of (and premium, if any) and interest on the Notes
will be paid in full when due, whether at Stated Maturity, by acceleration or otherwise (including the amount that would become due but
for the operation of the automatic stay under Section 362(a) of the Bankruptcy Law), together with interest on the overdue principal,
if any, and interest on any overdue interest, to the extent lawful, and all other obligations of the Issuer to the Holders or the Trustee
hereunder or thereunder will be paid in full or performed, all in accordance with the terms hereof and thereof; and (2) in case of any
extension of time of payment or renewal of any Notes or of any such other obligations, the same shall be paid in full when due or performed
in accordance with the terms of the extension or renewal, whether at Stated Maturity, by acceleration or otherwise, subject, however,
in the case of clauses (1) and (2) above, to the limitation set forth in Section 1204 hereof.

 

    -93- 

     

    

 

Each Guarantor hereby agrees (to the extent permitted
by applicable law) that its obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of
the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder with respect to any provisions
hereof or thereof, any release of any other Guarantor, the recovery of any judgment against the Issuer, any action to enforce the same
or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a Guarantor.

 

Each Guarantor hereby waives (to the extent permitted
by law) the benefits of diligence, presentment, demand for payment, filing of claims with a court in the event of insolvency or bankruptcy
of the Issuer, any right to require a proceeding first against the Issuer or any other Person, protest, notice and all demands whatsoever
and covenants that the Guarantee of such Guarantor shall not be discharged as to any Note except by complete performance of the obligations
contained in such Note, this Indenture and such Guarantee. Each Guarantor acknowledges that the Guarantee is a guarantee of payment, performance
and compliance when due and not of collection. Each of the Guarantors hereby agrees that, in the event of a default in payment of principal
(or premium, if any) or interest on such Note, whether at its Stated Maturity, by acceleration, purchase or otherwise, legal proceedings
may be instituted by the Trustee on behalf of, or by, the Holder of such Note, subject to the terms and conditions set forth in this Indenture,
directly against each of the Guarantors to enforce such Guarantor’s Guarantee without first proceeding against the Issuer or any
other Guarantor. Each Guarantor agrees that if, after the occurrence and during the continuance of an Event of Default, the Trustee or
any of the Holders are prevented by applicable law from exercising their respective rights to accelerate the Maturity of the Notes, to
collect interest on the Notes, or to enforce or exercise any other right or remedy with respect to the Notes, such Guarantor shall pay
to the Trustee for the account of the Holder, upon demand therefor, the amount that would otherwise have been due and payable had such
rights and remedies been permitted to be exercised by the Trustee or any of the Holders.

 

If any Holder or the Trustee is required by any
court or otherwise to return to the Issuer or any Guarantor, or any custodian, trustee, liquidator or other similar official acting in
relation to either the Issuer or any Guarantor, any amount paid by any of them to the Trustee or such Holder, the Guarantee of each of
the Guarantors, to the extent theretofore discharged, shall be reinstated in full force and effect. Each Guarantor further agrees that,
as between each Guarantor, on the one hand, and the Holders and the Trustee on the other hand, (1) subject to this Article Twelve, the
Maturity of the obligations guaranteed hereby may be accelerated as provided in Article Five hereof for the purposes of the Guarantee
of such Guarantor notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations
guaranteed hereby, and (2) in the event of any acceleration of such obligation as provided in Article Five hereof, such obligations (whether
or not due and payable) shall forthwith become due and payable by each Guarantor for the purpose of the Guarantee of such Guarantor.

 

Each Guarantee shall remain in full force and effect
and continue to be effective should any petition be filed by or against the Issuer for liquidation, reorganization, should the Issuer
become insolvent or make an assignment for the benefit of creditors or should a receiver or trustee be appointed for all or any significant
part of the Issuer’s assets, and shall, to the fullest extent permitted by law, continue to be effective or be reinstated, as the
case may be, if at any time payment and performance of the Notes are, pursuant to applicable law, rescinded or reduced in amount, or must
otherwise be restored or returned by any obligee on the Notes, whether as a “voidable preference,” “fraudulent transfer”
or otherwise, all as though such payment or performance had not been made. In the event that any payment or any part thereof, is rescinded,
reduced, restored or returned, the Notes shall, to the fullest extent permitted by law, be reinstated and deemed reduced only by such
amount paid and not so rescinded, reduced, restored or returned.

 

SECTION 1202.     
Severability. In case any provision of any Guarantee shall be invalid, illegal or unenforceable, the validity, legality,
and enforceability of the remaining provisions shall not in any way be affected or impaired thereby to the extent permitted by applicable
law.

 

SECTION 1203.      Restricted
Subsidiaries. The Issuer shall cause any Restricted Subsidiary required to guarantee payment of the Notes pursuant to the terms
and provisions of Section 1015 to execute and deliver to the Trustee any amendment or supplement to this Indenture in accordance
with the provisions of Article Nine of this Indenture pursuant to which such Restricted Subsidiary shall guarantee all of the
obligations on the Notes, whether for principal, premium, if any, interest (including interest accruing after the filing of, or
which would have accrued but for the filing of, a petition by or against the Issuer under any Bankruptcy Law, whether or not such
interest is allowed as a claim after such filing in any proceeding under such law) and other amounts due in connection therewith
(including any fees, expenses and indemnities), on an unsecured senior basis. Upon the execution of any such amendment or
supplement, the obligations of the Guarantors and any such Restricted Subsidiary under their respective Guarantees shall become
joint and several and each reference to the “Guarantor” in this Indenture shall, subject to Section 1208, be deemed to
refer to all Guarantors, including such Restricted Subsidiary. Such Guarantee shall be released in accordance with Section 803 and
Section 1208.

 

    -94- 

     

    

 

SECTION 1204.     
Limitation of Guarantors’ Liability. Each Guarantor and by its acceptance hereof each Holder confirms that it is the
intention of all such parties that the guarantee by each such Guarantor pursuant to its Guarantee not constitute a fraudulent transfer
or conveyance for purposes of the Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar
federal or state law or the provisions of its local law relating to fraudulent transfer or conveyance. To effectuate the foregoing intention,
the Holders and each such Guarantor hereby irrevocably agree that the obligations of such Guarantor under its Guarantee shall be limited
to the maximum amount that will not, after giving effect to all other contingent and fixed liabilities of such Guarantor and after giving
effect to any collections from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor
under its Guarantee or pursuant to this Section 1204, result in the obligations of such Guarantor under its Guarantee constituting such
fraudulent transfer or conveyance.

 

SECTION 1205.     
Contribution. In order to provide for just and equitable contribution among the Guarantors, the Guarantors agree that in
the event any payment or distribution is made by any Guarantor (a “Funding Guarantor”) under a Guarantee, such Funding
Guarantor shall be entitled to a contribution from all other Guarantors in a pro rata amount based on the Adjusted Net Assets (as
defined below) of each Guarantor (including the Funding Guarantor) for all payments, damages and expenses incurred by that Funding Guarantor
in discharging the Issuer’s obligations with respect to the Notes or any other Guarantor’s obligations with respect to the
Guarantee of such Guarantor. “Adjusted Net Assets” of such Guarantor at any date shall mean the lesser of (1) the amount
by which the fair value of the property of such Guarantor exceeds the total amount of liabilities, including contingent liabilities (after
giving effect to all other fixed and contingent liabilities incurred or assumed on such date), but excluding liabilities under the Guarantee
of such Guarantor at such date and (2) the amount by which the present fair salable value of the assets of such Guarantor at such date
exceeds the amount that will be required to pay the probable liability of such Guarantor on its debts (after giving effect to all other
fixed and contingent liabilities incurred or assumed on such date), excluding debt in respect of the Guarantee of such Guarantor, as they
become absolute and matured.

 

SECTION 1206.     
Subrogation. Each Guarantor shall be subrogated to all rights of Holders against the Issuer in respect of any amounts paid
by any Guarantor pursuant to the provisions of Section 1201; provided that, if an Event of Default has occurred and is continuing,
no Guarantor shall be entitled to enforce or receive any payments arising out of, or based upon, such right of subrogation until all amounts
then due and payable by the Issuer under this Indenture or the Notes shall have been paid in full.

 

SECTION 1207.     
Reinstatement. Each Guarantor hereby agrees (and each Person who becomes a Guarantor shall agree) that the Guarantee provided
for in Section 1201 shall continue to be effective or be reinstated, as the case may be, if at any time, payment, or any part thereof,
of any obligations or interest thereon is rescinded or must otherwise be restored by a Holder to the Issuer upon the bankruptcy or insolvency
of the Issuer or any Guarantor.

 

SECTION 1208.     
Release of a Guarantor. Any Guarantee by a Guarantor of the Notes shall be automatically and unconditionally released and
discharged upon:

 

(1)               
 

 

(A)              
any sale, exchange or transfer (by merger or otherwise) of (i) the Capital Stock of such Guarantor (including any sale, exchange
or transfer) after which the applicable Guarantor is no longer a Restricted Subsidiary or (ii) all the assets of such Guarantor, which
sale, exchange or transfer is made in compliance with the applicable provisions of this Indenture;

 

(B)               the
release or discharge of the guarantee by, or direct obligation of, such Guarantor with respect to the Senior Credit Facility or the
guarantee or direct obligation which resulted in the creation of such Guarantee, except a discharge or release by or as a result of
payment under such guarantee or direct obligation;

 

    -95- 

     

    

 

(C)              
the designation of any Restricted Subsidiary that is a Guarantor as an Unrestricted Subsidiary in compliance with the applicable
provisions of this Indenture;

 

(D)              
the exercise of the Legal Defeasance of the Notes under Section 1302 hereof, and the Covenant Defeasance of the Notes under Section
1303 hereof, or if the Issuer’s obligations under this Indenture are discharged in accordance with Section 401 of this Indenture;

 

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

 

(F)               
as described under Section 901 or 902; and

 

(2)               
such Guarantor delivering to the Trustee an Officer’s Certificate stating that all conditions precedent herein provided for
relating to such transaction have been complied with.

 

SECTION 1209.     
Benefits Acknowledged. Each Guarantor acknowledges that it will receive direct and indirect benefits from the financing
arrangements contemplated by this Indenture and from its guarantee and waivers pursuant to its Guarantees under this Article Twelve.

LEGAL DEFEASANCE AND COVENANT DEFEASANCE

 

SECTION 1301.     
Issuer’s Option to Effect Legal Defeasance or Covenant Defeasance. The Issuer may, at its option, at any time, with
respect to the Notes, elect to have either Section 1302 or Section 1303 be applied to all Outstanding Notes upon compliance with the conditions
set forth below in this Article Thirteen.

 

SECTION 1302.     
Legal Defeasance and Discharge. Upon the Issuer’s exercise under Section 1301 of the option applicable to this Section
1302, each of the Issuer and the Guarantors shall be deemed to have been discharged from its respective obligations with respect to all
Outstanding Notes on the date the conditions set forth in Section 1304 are satisfied (hereinafter, “Legal Defeasance”).
For this purpose, such Legal Defeasance means that each of the Issuer and the Guarantors shall be deemed to have paid and discharged the
entire indebtedness represented by the Outstanding Notes, which shall thereafter be deemed to be “Outstanding” only for the
purposes of Section 1305 and the other Sections of this Indenture referred to in clauses (1) and (2) below, and to have satisfied all
its other obligations under such Notes and this Indenture insofar as such Notes are concerned (and the Trustee, at the expense of the
Issuer, shall execute proper instruments acknowledging the same), except for the following which shall survive until otherwise terminated
or discharged hereunder: (1) the rights of Holders of Outstanding Notes to receive payments in respect of the principal of (and premium,
if any, on) and interest on such Notes when such payments are due, solely out of the trust described in Section 1304, (2) the Issuer’s
obligations with respect to such Notes under Sections 304, 305, 306, 1002 and 1003, (3) the rights, powers, trusts, duties and immunities
of the Trustee hereunder, and the obligations of each of the Guarantors and the Issuer in connection therewith and (4) this Article Thirteen.
Subject to compliance with this Article Thirteen, the Issuer may exercise its option under this Section 1302 notwithstanding the prior
exercise of its option under Section 1303 with respect to the Notes.

 

SECTION 1303.      Covenant
Defeasance. Upon the Issuer’s exercise under Section 1301 of the option applicable to this Section 1303, each of the
Issuer and the Guarantors shall be released from its respective obligations under any covenant contained in Sections 801 and 802 and
in Sections 1009 through and including 1019 with respect to the Outstanding Notes on and after the date the conditions set forth
below are satisfied (hereinafter, “Covenant Defeasance”), and the Notes shall thereafter be deemed not to be
 “Outstanding” for the purposes of any direction, waiver, consent or declaration or Act of Holders (and the consequences
of any thereof) in connection with such covenants, but shall continue to be deemed “Outstanding” for all other purposes
hereunder. For this purpose, such Covenant Defeasance means that, with respect to the Outstanding Notes, the Issuer or any
Guarantor, as applicable, may omit to comply with and shall have no liability in respect of any term, condition or limitation set
forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by
reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply
shall not constitute a Default or an Event of Default under Sections 501(3), 501(4), 501(5), and 501(7) and, with respect to only
any Significant Subsidiary and not the Issuer, Section 501(6), but, except as specified above, the remainder of this Indenture and
such Notes shall be unaffected thereby.

 

    -96- 

     

    

 

SECTION 1304.     
Conditions to Legal Defeasance or Covenant Defeasance. The following shall be the conditions to application of either Section
1302 or Section 1303 to the Outstanding Notes:

 

(1)               
the Issuer shall irrevocably have deposited or caused to be deposited with the Trustee (or another trustee satisfying the requirements
of Section 608 who shall agree to comply with the provisions of this Article Thirteen applicable to it) as trust funds in trust for the
purpose of making the following payments, specifically pledged as security for, and dedicated solely to the benefit of the Holders of
such Notes (A) cash in U.S. dollars, or (B) Government Securities, or (C) a combination thereof, in such amounts as will be sufficient,
in the written opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof
delivered to the Trustee, to pay and discharge, and which shall be applied by the Trustee (or other qualifying trustee) to pay and discharge,
the principal of (and premium, if any) and interest on the Outstanding Notes at the Stated Maturity (or Redemption Date, if applicable
and so indicated to the Trustee in writing); provided that the Trustee shall have been irrevocably instructed to apply such cash
or the proceeds of such Government Securities or combination thereof to said payments with respect to the Notes. Before such a deposit,
the Issuer may give to the Trustee, in accordance with Section 1103 hereof, a notice of its election to redeem all of the Outstanding
Notes at a future date in accordance with Article Eleven hereof, which notice shall be irrevocable. Such irrevocable redemption notice,
if given, shall be given effect in applying the foregoing;

 

(2)               
in the case of Legal Defeasance, the Issuer shall have delivered to the Trustee an Opinion of Counsel in the United States acceptable
to the Trustee confirming that, subject to customary assumptions and exclusions,

 

(A)              
the Issuer has received from, or there has been published by, the United States Internal Revenue Service a ruling, or

 

(B)              
since the issuance of the Notes, there has been a change in the applicable U.S. Federal income tax law,

 

in either case to the effect that, and based thereon such
Opinion of Counsel in the United States shall confirm that, subject to customary assumptions and exclusions, the beneficial owners of
the Outstanding Notes will not recognize income, gain or loss for U.S. Federal income tax purposes as a result of such Legal 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 Legal Defeasance had not occurred;

 

(3)               
in the case of Covenant Defeasance, the Issuer shall have delivered to the Trustee an Opinion of Counsel in the United States acceptable
to the Trustee confirming that, subject to customary assumptions and exclusions, the beneficial owners of the Outstanding Notes will not
recognize income, gain or loss for U.S. Federal income tax purposes as a result of such Covenant 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 Covenant Defeasance
had not occurred;

 

(4)               
no Default or Event of Default (other than that resulting from borrowing funds to be applied to make such deposit and any similar
and simultaneous deposit relating to other Indebtedness, and, in each case the granting of Liens in connection therewith) with respect
to the Notes issued hereunder shall have occurred and be continuing on the date of such deposit;

 

    -97- 

     

    

 

(5)               
 such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under the Senior
Credit Facility or any other material agreement or instrument (other than this Indenture) to which, the Issuer or any Guarantor is a party
or by which the Issuer or any Guarantor is bound (other than that resulting from borrowing funds to be applied to make such deposit and
any similar and simultaneous deposit relating to other Indebtedness and, in each case, the granting of Liens in connection therewith);

 

(6)               
the Issuer shall have delivered to the Trustee an Opinion of Counsel to the effect that, as of the date of such opinion and subject
to customary assumptions and exclusions following the deposit, the trust funds will not be subject to the effect of Section 547 of Title
11 of the United States Code;

 

(7)               
the Issuer shall have delivered to the Trustee an Officer’s Certificate stating that the deposit was not made by the Issuer
with the intent of defeating, hindering, delaying or defrauding any creditors of the Issuer or any Guarantor or others; and

 

(8)               
the Issuer shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel each stating that all conditions
precedent provided for or relating to the Legal Defeasance or the Covenant Defeasance, as the case may be, have been complied with.

 

SECTION 1305.     
Deposited Money and Government Securities To Be Held in Trust Other Miscellaneous Provisions. Subject to the provisions
of the last paragraph of Section 1003, all cash and Government Securities (including the proceeds thereof) deposited with the Trustee
(or other qualifying trustee, collectively for purposes of this Section 1305, the “Qualifying Trustee”) pursuant to
Section 1304 in respect of the Outstanding Notes shall be held in trust and applied by the Qualifying Trustee, in accordance with the
provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Issuer acting
as its own Paying Agent) as the Qualifying Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon
in respect of principal (and premium, if any) and interest, but such money or Government Securities need not be segregated from other
funds except to the extent required by law.

 

The Issuer shall pay and indemnify the Qualifying
Trustee against any tax, fee or other charge imposed on or assessed against the Government Securities deposited pursuant to Section 1304
or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account
of the Holders of the Outstanding Notes.

 

Anything in this Article Thirteen to the contrary
notwithstanding, the Qualifying Trustee shall deliver or pay to the Issuer from time to time upon Issuer Request any money or Government
Securities held by it as provided in Section 1304 which, in the opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Qualifying Trustee, are in excess of the amount thereof which would then
be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance, as applicable, in accordance with this Article
Thirteen.

 

SECTION 1306.     
Reinstatement. If the Trustee or any Paying Agent is unable to apply any money or Government Securities in accordance with
Section 1305 by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting
such application, then the Issuer’s and each Guarantor’s obligations under this Indenture and the Outstanding Notes shall
be revived and reinstated as though no deposit had occurred pursuant to Section 1302 or 1303, as the case may be, until such time as the
Trustee or Paying Agent is permitted to apply all such money or Government Securities in accordance with Section 1305; provided that,
if the Issuer makes any payment of principal of (or premium, if any) or interest on any Note following the reinstatement of its obligations,
the Issuer shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government Securities
held by the Trustee or Paying Agent.

Non-U.S. Persons or U.S. Persons who purchased such interests in a transaction that did not require registration under the Securities
Act and (ii) in the case of an exchange for a Definitive Note, in compliance with the requirements of Section 2.4(a) hereof.

 

Beneficial interests in Regulation S Global Notes
may be exchanged for interests in Rule 144A Global Notes if (1) such exchange occurs in connection with a transfer of Notes in compliance
with Rule 144A and (2) the transferor of the beneficial interest in the Regulation S Global Note, first delivers to the Trustee a written
certificate (in a form satisfactory to the Trustee) to the effect that the beneficial interest in the Regulation S Global Note is being
transferred to a Person (a) whom the transferor reasonably believes to be a QIB, (b) purchasing for its own account or the account of
a QIB in a transaction meeting the requirements of Rule 144A, and (c) in accordance with all applicable securities laws of the States
of the United States and other jurisdictions.

 

Beneficial interests in a Rule 144A Global Note
may be transferred to a Person who takes delivery in the form of an interest in a Regulation S Global Note, whether before or after the
expiration of the Distribution Compliance Period, only if the transferor first delivers to the Trustee a written certificate (in the form
provided in this Indenture) to the effect that such transfer is being made in accordance with Rule 903 or 904 of Regulation S or Rule
144 (if applicable).

 

The Rule 144A Global Note and the Regulation S
Global Note are collectively referred to herein as “Global Notes.” The aggregate principal amount of the Global Notes may
from time to time be increased or decreased by adjustments made on the records of the Trustee and the Depository or its nominee as hereinafter
provided.

 

(b)     Book-Entry
Provisions. This Section 2.1(b) shall apply only to a Global Note deposited with or on behalf of the Depository.

 

The Issuer shall execute and the Trustee
shall, in accordance with this Section 2.1(b), authenticate and deliver initially one or more Global Notes that (a) shall be
registered in the name of the Depository and (b) shall be delivered by the Trustee to such Depository or pursuant to such
Depository’s instructions or held by the Trustee as custodian for the Depository.

 

     

     

    

 

Members of, or participants in the Depository (“Agent
Members”) shall have no rights under this Indenture with respect to any Global Note held on their behalf by the Depository or by
the Trustee as the custodian of the Depository or under such Global Note, and the Issuer, the Trustee and any agent of the Issuer or the
Trustee shall be entitled to treat the Depository as the absolute owner of such Global Note for all purposes whatsoever. Notwithstanding
the foregoing, nothing herein shall prevent the Issuer, the Trustee or any agent of the Issuer or the Trustee from giving effect to any
written certification, proxy or other authorization furnished by the Depository or impair as between the Depository and its Agent Members,
the operation of customary practices of such Depository governing the exercise of the rights of a holder of a beneficial interest in any
Global Note.

 

(c)     Definitive
Notes. Except as provided in this Section 2.1, 2.3 or 2.4, owners of beneficial interests in Global Notes shall not be entitled to
receive physical delivery of Definitive Notes.

 

2.2     Authentication.
The Trustee shall authenticate and deliver: (1) on the Issue Date, an aggregate principal amount of $400,000,000 of the Issuer’s
4.125% Senior Notes due 2029 and (2) any Additional Notes for an original issue in an aggregate principal amount specified in the written
order of the Issuer pursuant to Section 202 of this Indenture, in each case upon a written order of the Issuer signed by two Officers
or by an Officer and either an Assistant Treasurer or an Assistant Secretary of the Issuer. Such order shall specify the amount of the
Notes to be authenticated and the date on which the original issue of Notes is to be authenticated and, in the case of any issuance of
Additional Notes pursuant to Section 313 of this Indenture, shall certify that such issuance is in compliance with Section 1011 of this
Indenture.

 

2.3     Transfer
and Exchange.

 

(a)     Transfer
and Exchange of Definitive Notes. When Definitive Notes are presented to the Note Registrar with a request:

 

(x)       to
register the transfer of such Definitive Notes; or

 

(y)       to
exchange such Definitive Notes for an equal principal amount of Definitive Notes of other authorized denominations,

 

the Note Registrar shall register the transfer or make the exchange
as requested if its reasonable requirements for such transaction are met; provided, however, that the Definitive Notes surrendered
for transfer or exchange:

 

(i)        shall
be duly endorsed or accompanied by a written instrument of transfer in form reasonably satisfactory to the Issuer and the Note Registrar,
duly executed by the Holder thereof or its attorney duly authorized in writing; and

 

(ii)       if
such Definitive Notes are required to bear a restricted notes legend, they are being transferred or exchanged pursuant to an effective
registration statement under the Securities Act, pursuant to Section 2.3(b) or pursuant to clause (A), (B) or (C) below, and are accompanied
by the following additional information and documents, as applicable:

 

(A)       if
such Definitive Notes are being delivered to the Note Registrar by a Holder for registration in the name of such Holder, without transfer,
a certification from such Holder to that effect; or

 

(B)       if
such Definitive Notes are being transferred to the Issuer, a certification to that effect; or

 

     

     

    

 

(C)       if
such Definitive Notes are being transferred (x) pursuant to an exemption from registration in accordance with Rule 144A, Regulation
S or Rule 144 under the Securities Act; or (y) in reliance upon another exemption from the requirements of the Securities Act: (i) a
certification to that effect (in the form set forth on the reverse of the Note) and (ii) if the Issuer so requests, an opinion of
counsel or other evidence reasonably satisfactory to it as to the compliance with the restrictions set forth in the legend set forth
in Section 2.3(e)(i).

 

(b)      Restrictions
on Transfer of a Definitive Note for a Beneficial Interest in a Global Note. A Definitive Note may not be exchanged for a beneficial
interest in a Rule 144A Global Note or a Regulation S Global Note except upon satisfaction of the requirements set forth below. Upon receipt
by the Trustee of a Definitive Note, duly endorsed or accompanied by appropriate instruments of transfer, in form satisfactory to the
Trustee, together with:

 

(i)       certification,
in the form set forth on the reverse of the Note, that such Definitive Note is either (A) being transferred to a QIB in accordance with
Rule 144A or (B) being transferred to an IAI or (C) being transferred after expiration of the Distribution Compliance Period by a Person
who initially purchased such Note in reliance on Regulation S to a buyer who elects to hold its interest in such Note in the form of a
beneficial interest in the Regulation S Global Note; and

 

(ii)      written
instructions directing the Trustee to make, or to direct the Notes Custodian to make, an adjustment on its books and records with respect
to such Rule 144A Global Note (in the case of a transfer pursuant to clause (b)(i)(A)) or Regulation S Global Note (in the case of a transfer
pursuant to clause (b)(i)(C)) to reflect an increase in the aggregate principal amount of the Notes represented by the Rule 144A Global
Note or Regulation S Global Note, as applicable, such instructions to contain information regarding the Agent Member account to be credited
with such increase,

 

then the Trustee shall cancel such Definitive Note and cause, or direct
the Notes Custodian to cause, in accordance with the standing instructions and procedures of the Depository and the Notes Custodian, the
aggregate principal amount of Notes represented by the Rule 144A Global Note or Regulation S Global Note, as applicable, to be increased
by the aggregate principal amount of the Definitive Note to be exchanged and shall credit or cause to be credited to the account of the
Person specified in such instructions a beneficial interest in the Rule 144A Global Note or Regulation S Global Note, as applicable, equal
to the principal amount of the Definitive Note so cancelled. If no Rule 144A Global Notes or Regulation S Global Notes, as applicable,
are then outstanding, the Issuer shall issue and the Trustee shall authenticate, upon written order of the Issuer in the form of an Officer’s
Certificate of the Issuer, a new Rule 144A Global Note or Regulation S Global Note, as applicable, in the appropriate principal amount.

 

(c)     Transfer
and Exchange of Global Notes.

 

(i)      The
transfer and exchange of Global Notes or beneficial interests therein shall be effected through the Depository, in accordance with this
Indenture (including applicable restrictions on transfer set forth herein, if any) and the procedures of the Depository therefor. A transferor
of a beneficial interest in a Global Note shall deliver to the Note Registrar a written order given in accordance with the Depository’s
procedures containing information regarding the participant account of the Depository to be credited with a beneficial interest in the
Global Note. The Note Registrar shall, in accordance with such instructions instruct the Depository to credit to the account of the Person
specified in such instructions a beneficial interest in the Global Note and to debit the account of the Person making the transfer the
beneficial interest in the Global Note being transferred.

 

(ii)     If
the proposed transfer is a transfer of a beneficial interest in one Global Note to a beneficial interest in another Global Note, the Note
Registrar shall reflect on its books and records the date and an increase in the principal amount of the Global Note to which such interest
is being transferred in an amount equal to the principal amount of the interest to be so transferred, and the Note Registrar shall reflect
on its books and records the date and a corresponding decrease in the principal amount of the Global Note from which such interest is
being transferred.

 

(iii)    Notwithstanding
any other provisions of this Appendix (other than the provisions set forth in Section 2.4), a Global Note may not be transferred as a
whole except by the Depository to a nominee of the Depository or by a nominee of the Depository to the Depository or another nominee of
the Depository or by the Depository or any such nominee to a successor Depository or a nominee of such successor Depository.

 

     

     

    

 

(iv)    In
the event that a Global Note is exchanged for a Definitive Note pursuant to Section 2.4 of this Appendix, such Notes may be exchanged
only in accordance with such procedures as are substantially consistent with the provisions of this Section 2.3 (including the certification
requirements set forth on the reverse of the Notes intended to ensure that such transfers comply with Rule 144A, Regulation S or another
applicable exemption under the Securities Act, as the case may be) and such other procedures as may from time to time be adopted by the
Issuer.

 

(v)     During
the Distribution Compliance Period, beneficial ownership interests in Regulation S Global Notes may only be sold, pledged or transferred
in accordance with the Applicable Procedures and only (i) to the Issuer, (ii) in an offshore transaction in accordance with Regulation
S or (iii) pursuant to an effective registration statement under the Securities Act, in each case in accordance with any applicable securities
laws of any State of the United States.

 

(e)     Legend.

 

(i)      Except
as permitted by the following paragraphs (ii), (iii) and (iv), each Note certificate evidencing the Global Notes (and all Notes issued
in exchange therefor or in substitution thereof), in the case of Notes offered otherwise than in reliance on Regulation S shall bear a
legend in substantially the following form:

IT IS A “QUALIFIED INSTITUTIONAL BUYER” (AS DEFINED IN RULE 144A UNDER THE SECURITIES ACT), OR (B) IT IS NOT A U.S.
PERSON, IS NOT ACQUIRING THIS SECURITY FOR THE ACCOUNT OR BENEFIT OF A U.S. PERSON AND IS ACQUIRING THIS SECURITY IN AN OFFSHORE
TRANSACTION IN COMPLIANCE WITH REGULATION S UNDER THE SECURITIES ACT, (2) AGREES THAT IT WILL NOT UNTIL THE DATE THAT IS [IN THE
CASE OF RULE 144A NOTES: ONE YEAR AFTER THE LATER OF THE ORIGINAL ISSUE DATE HEREOF, THE ORIGINAL ISSUE DATE OF THE ISSUANCE OF ANY
ADDITIONAL NOTES AND THE LAST DATE ON WHICH THE ISSUER OR ANY AFFILIATE OF THE ISSUER WAS THE OWNER OF THIS SECURITY (OR ANY

ORIGINAL ISSUE DATE OF THE ISSUANCE OF ANY ADDITIONAL NOTES AND THE DATE ON WHICH THIS SECURITY (OR ANY PREDECESSOR OF SUCH
SECURITY) WAS FIRST OFFERED TO PERSONS OTHER THAN DISTRIBUTORS (AS DEFINED IN RULE 902 OF REGULATION S) IN RELIANCE ON REGULATION S]
OFFER, SELL OR OTHERWISE TRANSFER THIS SECURITY EXCEPT (A) TO THE ISSUER OR ANY SUBSIDIARY THEREOF, (B) INSIDE THE UNITED STATES TO
A QUALIFIED INSTITUTIONAL BUYER IN COMPLIANCE WITH RULE 144A UNDER THE SECURITIES ACT, (C) INSIDE THE UNITED STATES TO AN
INSTITUTIONAL “ACCREDITED INVESTOR” (AS DEFINED IN RULE 501(A)(1), (2), (3) OR (7) UNDER THE SECURITIES ACT) (AN
 “ACCREDITED INVESTOR”) THAT, PRIOR TO SUCH TRANSFER, FURNISHES (OR HAS FURNISHED ON ITS BEHALF BY A U.S. BROKER DEALER)
TO THE TRUSTEE A SIGNED LETTER CONTAINING CERTAIN REPRESENTATIONS AND AGREEMENTS RELATING TO THE RESTRICTIONS ON TRANSFER OF THE
NOTES (THE FORM OF WHICH LETTER CAN BE OBTAINED FROM SUCH TRUSTEE), (D) OUTSIDE THE UNITED STATES IN AN OFFSHORE TRANSACTION IN
COMPLIANCE WITH RULE 904 UNDER THE SECURITIES ACT (IF AVAILABLE), (E) PURSUANT TO THE EXEMPTION FROM REGISTRATION PROVIDED BY RULE
144 UNDER THE SECURITIES ACT (IF AVAILABLE) (PROVIDED THAT PRIOR TO SUCH TRANSFER, THE ISSUER MAY REQUIRE AN OPINION OF COUNSEL THAT
SUCH TRANSFER IS IN COMPLIANCE WITH THE SECURITIES ACT), (F) IN ACCORDANCE WITH ANOTHER EXEMPTION FROM THE REGISTRATION REQUIREMENTS
OF THE SECURITIES ACT (PROVIDED THAT PRIOR TO SUCH TRANSFER THE ISSUER MAY REQUIRE AN OPINION OF COUNSEL THAT SUCH TRANSFER IS IN
COMPLIANCE WITH THE SECURITIES ACT) OR (G) PURSUANT TO AN EFFECTIVE REGISTRATION STATEMENT UNDER THE SECURITIES ACT AND, IN EACH
CASE DESCRIBED IN CLAUSES (A) THROUGH (G), IN ACCORDANCE WITH ANY APPLICABLE SECURITIES LAW OF THE UNITED STATES OR ANY OTHER
JURISDICTION AND (3) AGREES FOR THE BENEFIT OF THE ISSUER THAT IT WILL GIVE TO EACH PERSON TO WHOM THIS SECURITY IS TRANSFERRED A
NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND. AS USED HEREIN, THE TERMS “OFFSHORE TRANSACTION,” “UNITED
STATES” AND “U.S. PERSON” HAVE THE MEANING GIVEN TO THEM BY REGULATION S UNDER THE SECURITIES ACT.

 

     

     

    

 

Each certificate evidencing a Note offered in reliance on Regulation
S shall, in addition to the foregoing, bear a legend in substantially the following form:

 

THIS NOTE (OR ITS PREDECESSOR) WAS ORIGINALLY
ISSUED IN A TRANSACTION ORIGINALLY EXEMPT FROM REGISTRATION UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”),
AND MAY NOT BE TRANSFERRED IN THE UNITED STATES OR TO, OR FOR THE ACCOUNT OR BENEFIT OF, ANY U.S. PERSON EXCEPT PURSUANT TO AN AVAILABLE
EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT AND ALL APPLICABLE STATE SECURITIES LAWS. TERMS USED ABOVE HAVE THE
MEANING GIVEN TO THEM IN REGULATION S UNDER THE SECURITIES ACT.

 

Each Definitive Note shall also bear the following additional legend:

 

IN CONNECTION WITH ANY TRANSFER, THE HOLDER WILL DELIVER TO THE
REGISTRAR AND TRANSFER AGENT SUCH CERTIFICATES AND OTHER INFORMATION AS SUCH TRANSFER AGENT MAY REASONABLY REQUIRE TO CONFIRM THAT THE
TRANSFER COMPLIES WITH THE FOREGOING RESTRICTIONS.

 

(ii)     Upon
any sale or transfer of a Transfer Restricted Note (including any Transfer Restricted Note represented by a Global Note) pursuant to Rule
144 under the Securities Act, the Note Registrar shall permit the transferee thereof to exchange such Transfer Restricted Note for a certificated
Note that does not bear the legend set forth above and rescind any restriction on the transfer of such Transfer Restricted Note, if the
transferor thereof certifies in writing to the Note Registrar that such sale or transfer was made in reliance on Rule 144 (such certification
to be in the form set forth on the reverse of the Note).

 

(f)      Cancellation
or Adjustment of Global Note. At such time as all beneficial interests in a Global Note have either been exchanged for Definitive
Notes, redeemed, purchased or cancelled, such Global Note shall be returned to the Depository for cancellation or retained and cancelled
by the Trustee. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for certificated Notes,
redeemed, purchased or cancelled, the principal amount of Notes represented by such Global Note shall be reduced and an adjustment shall
be made on the books and records of the Trustee (if it is then the Notes Custodian for such Global Note) with respect to such Global Note,
by the Trustee or the Notes Custodian, to reflect such reduction.

 

(g)     No
Obligation of the Trustee.

 

(i)      The
Trustee shall have no responsibility or obligation to any beneficial owner of a Global Note, a member of, or a participant in the
Depository or other Person with respect to the accuracy of the records of the Depository or its nominee or of any participant or
member thereof, with respect to any ownership interest in the Notes or with respect to the delivery to any participant, member,
beneficial owner or other Person (other than the Depository) of any notice (including any notice of redemption) or the payment of
any amount, under or with respect to such Notes. All notices and communications to be given to the Holders and all payments to be
made to Holders under the Notes shall be given or made only to or upon the order of the registered Holders (which shall be the
Depository or its nominee in the case of a Global Note). The rights of beneficial owners in any Global Note shall be exercised only
through the Depository subject to the applicable rules and procedures of the Depository. The Trustee may rely and shall be fully
protected in relying upon information furnished by the Depository with respect to its members, participants and any beneficial
owners.

 

     

     

    

 

(ii)     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 or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among
the Depository participants, members or beneficial owners in any Global Note) 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 to examine the same to determine substantial compliance as to form with the express requirements hereof.

 

2.4     Definitive
Notes.

 

(a)     A
Global Note deposited with the Depository or with the Trustee as Notes Custodian for the Depository pursuant to Section 2.1 shall be transferred
to the beneficial owners thereof in the form of Definitive Notes in an aggregate principal amount equal to the principal amount of such
Global Note, in exchange for such Global Note, only if such transfer complies with Section 2.3 hereof and (i) the Depository notifies
the Issuer that it is unwilling or unable to continue as Depository for such Global Note or if at any time such Depository ceases to be
a “clearing agency” registered under the Exchange Act and, in each case, a successor depository is not appointed by the Issuer
within 90 days of such notice, or (ii) a Default has occurred and is continuing or (iii) the Issuer, in its sole discretion, notifies
the Trustee in writing that it elects to cause the issuance of Definitive Notes under this Indenture.

 

(b)     Any
Global Note that is transferable to the beneficial owners thereof pursuant to this Section 2.4 shall be surrendered by the Depository
to the Trustee located at its principal Corporate Trust Office in the Borough of Manhattan, The City of New York, to be so transferred,
in whole or from time to time in part, without charge, and the Trustee shall authenticate and deliver, upon such transfer of each portion
of such Global Note, an equal aggregate principal amount of Definitive Notes of authorized denominations. Any portion of a Global Note
transferred pursuant to this Section 2.4 shall be executed, authenticated and delivered only in denominations of $2,000 principal amount
and any integral multiple of $1,000 in excess thereof and registered in such names as the Depository shall direct. Any Definitive Note
delivered in exchange for an interest in the Transfer Restricted Note shall, except as otherwise provided by Section 2.3(e) hereof, bear
the applicable restricted notes legend and definitive notes legend set forth in Exhibit 1 hereto.

 

(c)     Subject
to the provisions of Section 2.4(b) hereof, the registered Holder of a Global Note shall be entitled to grant proxies and otherwise authorize
any Person, including Agent Members and Persons that may hold interests through Agent Members, to take any action which a Holder is entitled
to take under this Indenture or the Notes.

 

(d)     In
the event of the occurrence of one of the events specified in Section 2.4(a) hereof, the Issuer shall promptly make available to the Trustee
a reasonable supply of Definitive Notes in definitive, fully registered form without interest coupons. In the event that such Definitive
Notes are not issued, the Issuer expressly acknowledges, with respect to the right of any Holder to pursue a remedy pursuant to this Indenture,
including pursuant to Section 507, the right of any beneficial owner of Notes to pursue such remedy with respect to the portion of the
Global Note that represents such beneficial owner’s Notes as if such Definitive Notes had been issued.

[FORM
OF REVERSE SIDE OF INITIAL NOTE]

4.125% Senior Note due 2029

 

	1.	Principal and Interest.

 

The Issuer will pay the principal of this Note
on April 15, 2029.

 

The Issuer promises to pay interest on the principal
amount of this Note on each Interest Payment Date, as set forth below, at the rate of 4.125% per annum (subject to adjustment as provided
below).

 

Interest will be payable semi-annually (to the
Holders of record of the Notes (or any Predecessor Notes) at the close of business on April 1 or October 1 immediately preceding the Interest
Payment Date) on each Interest Payment Date, commencing October 15, 2021.

 

Interest on this Note will accrue from the most
recent date to which interest has been paid or, if no interest has been paid, from April 13, 2021; provided that, if there is no
existing default in the payment of interest and if this Note is authenticated between a Regular Record Date referred to on the face hereof
and the next succeeding Interest Payment Date, interest shall accrue from such Interest Payment Date. Interest will be computed on the
basis of a 360-day year of twelve 30-day months.

 

The Issuer shall pay interest on overdue principal
and premium, if any, and interest on overdue installments of interest, to the extent lawful, at a rate per annum equal to the rate of
interest applicable to the Notes.

 

	2.	Method of Payment.

 

The Issuer will pay interest (except Defaulted
Interest) on the principal amount of the Notes on each April 15 and October 15 to the Persons who are Holders (as reflected in the Note
Register at the close of business on April 1 and October 1 immediately preceding the Interest Payment Date), in each case, even if the
Note is cancelled on registration of transfer or registration of exchange after such Regular Record Date; provided that, with respect
to the payment of principal, the Issuer will make payment to the Holder that surrenders this Note to any Paying Agent on or after April
15, 2029.

 

The Issuer will pay principal (and premium, if
any) and interest in U.S. dollars. However, the Issuer may pay principal (and premium, if any) and interest by its check payable in such
money. The Issuer may pay interest on the Notes either (a) by mailing a check for such interest to a Holder’s registered address
(as reflected in the Note Register) or (b) by wire transfer to an account located in the United States maintained by the payee. If a payment
date is a date other than a Business Day at a place of payment, payment may be made at that place on the next succeeding day that is a
Business Day and no interest shall accrue for the intervening period.

 

	3.	Paying Agent and Note Registrar.

 

The Issuer initially appoints U.S. Bank National
Association, in New York as Paying Agent and Note Registrar. The Issuer may change any Paying Agent or Note Registrar upon written notice

	4.	Indenture.

 

The Issuer issued the Notes under an Indenture
dated as of April 13, 2021 (the “Indenture”), among the Issuer, the Guarantors and the Trustee. Capitalized terms herein
are used as defined in the Indenture unless otherwise indicated. The terms of the Notes include those stated in the Indenture and those
made part of the Indenture by reference to the Trust Indenture Act. The Notes are subject to all such terms, and Holders are referred
to the Indenture and the Trust Indenture Act (to the extent applicable) for a statement of all such terms. To the extent permitted by
applicable law, in the event of any inconsistency between the terms of this Note and the terms of the Indenture, the terms of the Indenture
shall control.

 

The Notes are unsecured senior obligations of the
Issuer. The Indenture does not limit the aggregate principal amount of the Notes.

 

     

     

    

 

	5.	Redemption.

 

Optional Redemption. At any time prior to
April 15, 2024, the Issuer may redeem all or a part of the Notes, upon notice as described in Section 1105 of the Indenture, at a Redemption
Price equal to 100% of the principal amount of Notes redeemed plus the Applicable Premium as of, and accrued and unpaid interest,
if any, to, but excluding, the Redemption Date, subject to the rights of Holders of record of Notes on the relevant Regular Record Date
to receive interest due on the relevant Interest Payment Date.

 

On and after April 15, 2024, the Issuer may redeem
the Notes, in whole or in part, upon notice as described in Section 1105 of the Indenture, at the Redemption Prices (expressed as percentages
of principal amount of the Notes to be redeemed) set forth below, plus accrued and unpaid interest, if any, to, but excluding,

In addition, until April 15, 2024, the Issuer may,
at its option, upon notice as described in Section 1105 of the Indenture, on one or more occasions redeem up to 40% of the aggregate principal
amount of Notes issued under the Indenture at a Redemption Price equal to 104.125% of the aggregate principal amount thereof, plus
accrued and unpaid interest thereon, if any, to, but excluding, the applicable Redemption Date, subject to the right of Holders of
record of Notes on the relevant Regular Record Date to receive interest due on the relevant Interest Payment Date, with the net cash proceeds
of one or more Equity Offerings to the extent such net cash proceeds are received by or contributed to the Issuer; provided that
at least 50% of the sum of the aggregate principal amount of Notes originally issued under the Indenture (including any Additional Notes
issued under the Indenture after the Issue Date) remains outstanding immediately after the occurrence of each such redemption; provided,
further, that each such redemption occurs within 120 days of the date of closing of each such Equity Offering.

 

	6.	Repurchase upon a Change of Control and Asset Sales.

 

Upon the occurrence of (a) a Change of Control,
the Holders of the Notes will have the right to require that the Issuer purchase such Holder’s outstanding Notes, in whole or in
part, at a purchase price of 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to, but excluding,
the date of purchase and (b) Asset Sales, the Issuer may be obligated to make offers to purchase Notes and Senior Indebtedness of the
Issuer with a portion of the Net Proceeds of such Asset Sales at a Redemption Price of 100% of the principal amount thereof plus
accrued and unpaid interest, if any, to, but excluding, the date of purchase.

The Notes are in registered form without coupons
in denominations of $2,000 principal amount and integral multiples of $1,000 in excess thereof. A Holder may transfer or exchange Notes
in accordance with the Indenture. The Note Registrar and the Trustee may require a Holder, among other things, to furnish appropriate
endorsements and transfer documents and the Issuer may require a Holder to pay any taxes and fees required by law or permitted by the
Indenture. The Issuer is not required to transfer or exchange any Notes selected for redemption or tendered (and not withdrawn) for repurchase
in connection with a Change of Control Offer, an Asset Sale Offer or other tender offer. Also, the Issuer is not required to transfer
or exchange any Notes for a period of 15 days before a selection of Notes to be redeemed or within 15 days before an Interest Payment

	8.	Persons Deemed Owners.

 

A registered Holder shall be treated as the owner
of a Note for all purposes.

 

	9.	Unclaimed Money.

 

If money for the payment of principal (premium,
if any) or interest remains unclaimed for two years, the Trustee and the Paying Agent will pay the money back to the Issuer at its written
request. After that, Holders entitled to the money must look to the Issuer for payment, unless an abandoned property law designates another
Person, and all liability of the Trustee and such Paying Agent with respect to such money shall cease.

 

	10.	Discharge and Defeasance Prior to Redemption or Maturity.

 

If the Issuer irrevocably deposits, or causes to
be deposited, with the Trustee money or Government Securities sufficient to pay the then outstanding principal of (premium, if any) and
accrued interest on the Notes (a) to the Redemption Date or Maturity, the Issuer will be discharged from its obligations under the Indenture
and the Notes, except in certain circumstances for certain covenants thereof, and (b) to the Stated Maturity, the Issuer will be discharged
from certain covenants set forth in the Indenture.

 

	11.	Amendment; Supplement; Waiver.

 

Subject to certain exceptions, the Indenture, the
Notes and any related Guarantee may be amended or supplemented with the consent of the Holders of at least a majority in aggregate principal
amount of the Outstanding Notes, including consents obtained in connection with a purchase of, or tender offer or exchange offer for the
Notes, and any existing Default or Event of Default or compliance with any provision of the Indenture or the Notes may be waived with
the consent of the Holders of a majority in aggregate principal amount of the Outstanding Notes, including consents obtained in connection
with a purchase of, or tender offer or exchange offer for, Notes, other than Notes beneficially owned by the Issuer or its Affiliates.
Without notice to or the consent of any Holder, the parties thereto may amend or supplement the Indenture or the Notes to, among other
things, cure any ambiguity, omission, mistake, defect or inconsistency and make any change that does not adversely affect the rights of
any Holder. For purposes of determining whether any Holder shall be disregarded for purposes of such consent, only Notes which a Responsible
Officer of the Trustee actually knows to be beneficially owned by the Issuer or its Affiliates shall be disregarded.

 

	12.	Restrictive Covenants.

 

The Indenture contains certain covenants, including
covenants with respect to the following matters: (i) Restricted Payments; (ii) incurrence of Indebtedness and Issuance of Disqualified
Stock; (iii) Liens; (iv) transactions with Affiliates; (v) dividend and other payment restrictions affecting Restricted Subsidiaries;

a Change of Control; and (ix) disposition of proceeds of Asset Sales. Within 120 days (or the successor time period then in effect under
the rules and regulations of the Exchange Act) after the end of each fiscal year, the Issuer must report to the Trustee on compliance
with such limitations.

 

	13.	Successor Persons.

 

When a successor Person or other entity assumes
all the obligations of its predecessor under the Notes and the Indenture, the predecessor Person will be released from those obligations.

 

     

     

    

 

	14.	Remedies for Events of Default.

 

If an Event of Default, as
defined in the Indenture, occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the
Outstanding Notes may declare all the Notes to be immediately due and payable. If a bankruptcy or insolvency default with respect to
the Issuer occurs and is continuing, the Notes automatically become immediately due and payable. Subject to the provisions of the
Indenture relating to the duties of the Trustee, in case an Event of Default occurs and is continuing, the Trustee shall be under no
obligation to exercise any rights or powers under the Indenture at the request or direction of any of the Holders of the Notes
unless such Holders have offered indemnity or security against any loss, liability or expense satisfactory to the Trustee. Subject
to certain restrictions, the Holders of a majority in principal amount of the Outstanding Notes are given the right to 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 that
the Trustee determines is unduly prejudicial to the rights of any other Holder or that would involve the Trustee in personal
liability.

 

	15.	Guarantees.

 

The Issuer’s obligations under the Notes
are fully, irrevocably and unconditionally guaranteed on a senior unsecured basis, to the extent set forth in the Indenture, by each of
the Guarantors.

 

	16.	Trustee Dealings with Issuer.

 

The Trustee under the Indenture, in its individual
or any other capacity, may become the owner or pledgee of Notes and may make loans to, accept deposits from, perform services for, and
otherwise deal with, the Issuer and its Affiliates as if it were not the Trustee.

 

	17.	Authentication.

 

This Note shall not be valid until the Trustee
manually signs the certificate of authentication on the other side of this Note.

 

	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 right of survivorship and

Committee on Uniform Security Identification Procedures, the Issuer has caused CUSIP numbers to be printed on the Notes and the Trustee
may use CUSIP numbers in notices as a convenience to Holders. No representation is made as to the accuracy of such numbers either as printed
on the Notes or as contained in any notice and reliance may be placed only on the other identification numbers placed thereon.

FORM OF SUPPLEMENTAL INDENTURE

TO BE DELIVERED BY SUBSEQUENT GUARANTORS

 

SUPPLEMENTAL INDENTURE (this “Supplemental
Indenture”), dated as of ______________, 20__, among BWX Technologies, Inc. (the “Issuer”), (__________________),
(the “Guaranteeing Subsidiary”), a subsidiary of the Issuer and U.S. Bank National Association, as trustee under the
Indenture referred to below (the “Trustee”).

 

W I T N E S S E T H

 

WHEREAS, the Issuer has heretofore executed and
delivered to the Trustee an indenture (the “Indenture”), dated as of April 13, 2021 providing for the issuance of 4.125%
Senior Notes due 2029 (the “Notes”);

 

WHEREAS, the Indenture provides that under certain
circumstances the Guaranteeing Subsidiary shall execute and deliver to the Trustee a supplemental indenture pursuant to which the Guaranteeing
Subsidiary shall unconditionally guarantee all of the Issuer’s Obligations under the Notes and the Indenture on the terms and conditions
set forth herein (the “Guarantee”); and

 

WHEREAS, pursuant to Section 901 of the Indenture,
the Trustee is authorized to execute and deliver this Supplemental Indenture.

 

NOW, THEREFORE, in consideration of the foregoing
and for other good and valuable consideration, the receipt of which is hereby acknowledged, the Guaranteeing Subsidiary and the Trustee
mutually covenant and agree for the equal and ratable benefit of the Holders of the Notes as follows:

 

1.       CAPITALIZED
TERMS. Capitalized terms used herein without definition shall have the meanings assigned to them in the Indenture.

The parties may sign any number of copies of this Supplemental Indenture. Each signed copy shall be an original, but all of them together
represent the same agreement. The exchange of copies of the Supplemental Indenture and of signature pages by facsimile or PDF transmission
shall constitute effective execution and delivery of the Supplemental Indenture as to the parties hereto and may be used in lieu of the
original Supplemental 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.

 

6.       EFFECT
OF HEADINGS. The Section headings herein are for convenience or reference only and are not intended to be considered a part hereof and
shall not affect the construction hereof.

 

7.       THE
TRUSTEE. The Trustee shall not be responsible in any manner whatsoever for or in respect of the validity or sufficiency of this Supplemental
Indenture or for or in respect of the recitals contained herein, all of which recitals are made solely by the Guaranteeing Subsidiary
and the Issuer.

 

    Exh. A-1

this Supplemental Indenture to be duly executed, all as of the date first above written.
