On October 21, 2026, Select Water Holdings LLC

(the “Issuer”), a subsidiary of Select Water Solutions, Inc. (the “Company”), issued $900 million aggregate principal

amount of its 7.625% Senior Notes due 2034 (the “Notes”). The Notes were issued pursuant to the indenture, dated as of October

21, 2026 (the “Indenture”), by and among the Issuer, the guarantors named therein (the “Guarantors”) and U.S.

Bank Trust Company, National Association, as trustee (the “Trustee”). Additional information regarding the Notes and the Indenture,

pursuant to which such Notes were issued, is set forth below.

Indenture and Senior Notes

The Notes are senior unsecured obligations of

the Issuer. The Notes are fully and unconditionally guaranteed on a senior unsecured basis by the existing subsidiaries of the Issuer

that guarantee its indebtedness under its revolving credit facility. The Notes are not guaranteed by the Company or SES Holdings, LLC

(“SES Holdings”), and neither the Company nor SES Holdings is a party to the Indenture.

Maturity

and Interest

The Notes will mature on November 1,

2034. The Notes bear interest at the rate of 7.625% per annum, payable semi-annually in arrears on each May 1 and November 1, with

interest payments on the Notes commencing May 1, 2027.

Optional

Redemption

At any time prior to November 1, 2029, the Issuer

may redeem up to 40% of the aggregate principal amount of the Notes with an amount of cash not greater than the net cash proceeds of certain

equity offerings at a redemption price equal to 107.625% of the principal amount of the Notes redeemed, plus accrued and unpaid interest,

if any, to, but excluding, the redemption date, if at least 50% of the aggregate principal amount of the Notes remains outstanding immediately

after such redemption and the redemption occurs within 180 days of the closing date of such equity offering.

At any time prior to November 1, 2029, the Issuer

may, on any one or more occasions, redeem all or a part of the Notes at a redemption price equal to 100% of the principal amount of the

Notes redeemed, plus a “make-whole” premium and accrued and unpaid interest, if any, to, but excluding, the redemption date.

On or after November 1, 2029, the Issuer may redeem

the Notes, in whole or in part, at the redemption prices set forth below, plus accrued and unpaid interest, if any, to, but excluding,

the redemption date, subject to the right of holders of record on the relevant record date to receive interest due on the relevant interest

payment date, if redeemed during the twelve-month period beginning on November 1 of the years indicated below:

Year

Percentage

2029

103.813 %

2030

101.906 %

2031 and thereafter

100.000 %

Change of

Control

If a Change of Control (as defined in the Indenture)

occurs (along with a downgrade of the Notes by two rating agencies), the Issuer may be required to offer to purchase the Notes at a purchase

price equal to 101% of the principal amount, plus accrued and unpaid interest, if any, to the purchase date.

Certain

Covenants

The Indenture contains covenants that, among other

things, limit the ability of the Issuer and its restricted subsidiaries to: (i) incur or guarantee additional indebtedness or issue certain

types of preferred stock; (ii) pay dividends or distributions in respect of its equity or redeem, repurchase or retire its equity or subordinated

indebtedness; (iii) transfer or sell assets; (iv) make investments; (v) create certain liens; (vi) enter into agreements that restrict

dividends or other payments from any non-Guarantor restricted subsidiary to it; (vii) consolidate, merge or transfer all or substantially

all of its assets; (viii) engage in transactions with affiliates; and (ix) create unrestricted subsidiaries.

Events of

Default

If an Event of Default (as defined in the Indenture)

occurs and is continuing under the Indenture, the Trustee or holders of at least 25% in aggregate principal amount of the then outstanding

Notes may declare the principal of, and accrued and unpaid interest, if any, on all the then outstanding Notes to be due and payable immediately;

provided that the Notes will be due and payable immediately without further action or notice if such an Event of Default results from

certain events of bankruptcy or insolvency with respect to the Issuer, any restricted subsidiary of the Issuer that is a significant subsidiary

or any group of restricted subsidiaries of the Issuer that, taken together, would constitute a significant subsidiary.

Special

Mandatory Redemption

If (i) the Company’s previously announced

acquisition of Pilot Water Solutions LLC (the “Pilot Water Acquisition”) has not been completed on or before March 1, 2027

(or such later date as the outside date under the related acquisition agreement may be extended by agreement of the parties thereto) (the

“Outside Date”), or (ii) prior to the Outside Date, the Issuer notifies the Trustee in writing that the acquisition agreement

has been terminated without the closing occurring thereunder or that the Issuer will not pursue the consummation of the Pilot Water Acquisition,

the Issuer will be required to redeem an aggregate principal amount of the Notes equal to the excess, if any, of (x) the aggregate principal

amount of the Notes issued on the issue date over (y) $450.0 million, at a redemption price equal to the issue price of the Notes to be

redeemed, plus accrued and unpaid interest to, but excluding, the special mandatory redemption date.

“Attributable Debt” in respect

of a sale-and-leaseback transaction means, at the time of determination, the present value of the obligation of the lessee for net rental

payments during the remaining term of the lease included in such sale-and-leaseback transaction including any period for which such lease

has been extended or may, at the option of the lessor, be extended. As used in the preceding sentence, “net rental payments”

under any lease for any such period shall mean the sum of rental and other payments required to be paid with respect to such period by

the lessee thereunder, excluding any amounts required to be paid by such lessee on account of maintenance and repairs, insurance, taxes,

assessments, water rates or similar charges. In the case of any lease that is terminable by the lessee upon payment of penalty, such net

rental payment shall also include the amount of such penalty, but no rent shall be considered as required to be paid under such lease

subsequent to the first date upon which it may be so terminated. For purposes of this definition, present value shall be calculated using

a discount rate equal to the rate of interest implicit in the subject transaction, determined in accordance with GAAP; provided,

however, that if such sale-and-leaseback transaction results in a Finance Lease Obligation, the amount of Indebtedness represented

thereby will be determined in accordance with the definition of “Finance Lease Obligation.”

“Bankruptcy Law” means Title

11, U.S. Code or any similar federal or state law for the relief of debtors.

“Beneficial Owner” has the meaning

assigned to such term in Rule 13d-3 and Rule 13d-5 under the Exchange Act, except that in calculating the beneficial ownership

of any particular “person” (as that term is used in Section 13(d)(3) of the Exchange Act), such “person”

will be deemed to have beneficial ownership of all securities that such “person” has the right to acquire by conversion or

exercise of other securities, whether such right is currently exercisable or is exercisable only after the passage of time. The terms

“Beneficial Ownership,” “Beneficially Owns” and “Beneficially Owned” have a corresponding meaning.

For purposes of this definition, a Person shall be deemed not to Beneficially Own securities that are the subject of a stock or unit purchase

agreement, merger agreement or similar agreement until consummation of the transactions or, as applicable, series of related transactions

contemplated thereby.

“Board of Directors” means:

(1) with respect to a corporation,

the board of directors of the corporation or any committee thereof duly authorized to act on behalf of such board;

(2) with respect to a partnership,

the board of directors, board of managers or other governing body of the general partner of the partnership, or any committee thereof

duly authorized to act on behalf of such board;

company, the board of directors or board of managers, the managing member or members or any controlling committee of managing members

thereof or other governing body;

(4) with respect to any other Person,

(5) with respect to references to

the Board of Directors of the Company, such references shall include the Board of Directors of the Parent.

“Business Day” means any day

other than a Legal Holiday.

“Capital Stock” means:

(1) in the case of a corporation,

corporate stock;

(2) in the case of an association

or business entity, any and all shares, interests, participations, rights or other equivalents (however designated) of corporate stock;

(3) in the case of a partnership

or limited liability company, partnership interests (whether general or limited) or membership interests; and

(4) any other interest or participation

that confers on a Person the right to receive a share of the profits and losses of, or distributions of assets of, the issuing Person,

but excluding from all of the foregoing any debt securities convertible into Capital Stock, whether or not such debt securities include

any right of participation with Capital Stock.

“Cash Equivalents” means:

(1) securities issued or fully guaranteed

or insured by the United States government or any agency thereof having maturities of not more than twenty-four (24) months from the date

of acquisition thereof;

(2) time deposits with, certificates

of deposit, bankers’ acceptances or Eurodollar time deposits of, any commercial bank that is a lender under the Credit Agreement

or (a) is organized under the laws of the United States of America, any state thereof or the District of Columbia or is the principal

at the time of acquisition and such financial institution otherwise meets the requirements of clauses (2)(a) and (c) of this

definition, in each case having a tenor of not more than 270 days;

(4) taxable and tax-exempt municipal

securities rated at least A- (or then equivalent grade) by S&P and A3 (or then equivalent grade) by Moody’s, including variable

(a)   With

respect to any (x) Restricted Payment, Investment or acquisition, in each case, the consummation by the Company or any Subsidiary

of which is not conditioned on the availability of, or on obtaining, third-party financing for such Investment or acquisition (whether

by merger, amalgamation, consolidation or other business combination or the acquisition of Capital Stock or otherwise) as applicable and

(y) redemption, repurchase, defeasance, satisfaction and discharge or repayment of Indebtedness, Disqualified Equity, Designated

Preferred Stock or Preferred Stock requiring irrevocable notice in advance of such redemption, repurchase, defeasance, satisfaction and

discharge or repayment and with respect to which such irrevocable notice has been delivered (any transaction described in clauses (x) or

(y), a “Limited Condition Transaction”), in each case for purposes of determining:

(1) whether any Indebtedness (including

Acquired Debt), Designated Preferred Stock or Disqualified Equity that is being incurred or issued in connection with such Limited Condition

Transaction is permitted to be incurred in compliance with Section 4.09;

(2) whether any Lien being incurred

in connection with such Limited Condition Transaction or to secure any such Indebtedness or Disqualified Equity or Designated Preferred

Stock is permitted to be incurred in accordance with Section 4.12 or the definition of “Permitted Liens”;

(3) whether any other transaction

(including any Investment or Restricted Payment) undertaken or proposed to be undertaken in connection with such Limited Condition Transaction

complies with the covenants or agreements contained in this Indenture or the Notes; and

(4) any calculation of the Consolidated

Leverage Ratio, Fixed Charge Coverage Ratio, Consolidated Net Income, and/or Consolidated Cash Flow and/or Consolidated Net Tangible Assets

and whether a Default or Event of Default exists in connection with the foregoing;

at the option of the Company, the date that the definitive

agreement (or other relevant definitive documentation) for such Limited Condition Transaction is entered into (the “Transaction

Agreement Date”) may be used as the applicable date of determination, as the case may be, in each case 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” and if the Company or the Restricted Subsidiaries could have taken such action on the relevant Transaction Agreement Date

in compliance with the applicable ratios or other provisions, such provisions shall be deemed to have been complied with. For the avoidance

of doubt, if the Company elects to use the Transaction Agreement Date as the applicable date of determination in accordance with the foregoing,

(a) such election may not be revoked, (b) any fluctuation or change in the Consolidated Leverage Ratio, Fixed Charge Coverage

Ratio, Consolidated Net Income, Consolidated Cash Flow or Consolidated Net Tangible Assets of the Company, the target business, or assets

to be acquired subsequent to the Transaction Agreement Date and prior to the consummation of such Limited Condition Transaction, will

not be taken into account for purposes of determining whether any Investment, Restricted Payment, Indebtedness, Designated Preferred

Stock, Disqualified Equity or Lien that is being made, incurred or issued in connection with such Limited Condition Transaction is permitted

to be made, incurred or issued or in connection with compliance by the Company or any of the Restricted Subsidiaries with any other provision

of this Indenture or the Notes or any other action or transaction undertaken in connection with such Limited Condition Transaction and

(c) until such Limited Condition Transaction is consummated or the definitive agreements related thereto are terminated, such Limited

Condition Transaction and all transactions proposed to be undertaken in connection therewith (including the making of any Restricted Payment,

or Investments, or the incurrence of Indebtedness and Liens) will be given pro forma effect when determining compliance of other transactions

(including the making of any Restricted Payment, or Investments, or the incurrence or issuance of Indebtedness, Designated Preferred Stock,

Disqualified Equity and Liens unrelated to such Investment, acquisition or repayment, repurchase or refinancing of Indebtedness) that

are consummated after the Transaction Agreement Date and on or prior to the consummation of such Limited Condition Transaction and any

such transactions (including any incurrence or issuance of Indebtedness, Designated Preferred Stock, or Disqualified Equity and the use

of proceeds thereof) will be deemed to have occurred on the Transaction Agreement Date 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 Transaction;

provided that for purposes of any such calculation of the Fixed Charge Coverage Ratio, Fixed Charges will be calculated using an assumed

interest rate for the Indebtedness to be incurred in connection with such Limited Condition Transaction based on the indicative interest

margin contained in any financing commitment documentation with respect to such Indebtedness or, if no such indicative interest margin

exists, as reasonably determined by the Company in good faith. Each item of Indebtedness, Designated Preferred Stock, or Disqualified

Equity that is incurred or issued, each Lien incurred and each other transaction undertaken will be deemed to have been incurred, issued

or taken first, to the extent available, pursuant to the relevant Fixed Charge Coverage Ratio or Consolidated Leverage Ratio test.

(b)   Compliance

with any requirement relating to absence of Default or Event of Default in respect of any incurrence of Indebtedness, issuance of Disqualified

Equity or Designated Preferred Stock, creation of a Lien, Asset Sale, Investment, Restricted Subsidiary or Unrestricted Subsidiary

designation or repayment of Indebtedness, Designated Preferred Stock, or Disqualified Equity in connection with a Limited Condition Transaction

for which the Company has elected to test such actions as of the Transaction Agreement Date, may be determined as of the Transaction Agreement

Date and not as of any later date as would otherwise be required under this Indenture.

The terms and provisions contained in

the Notes will constitute, and are hereby expressly made, a part of this Indenture and the Company, 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

therein and each shall provide that it represents the aggregate principal amount of outstanding Notes from time to time endorsed thereon

and that the aggregate principal amount of outstanding Notes represented thereby may from time to time be reduced or increased, as appropriate,

in the aggregate principal amount of outstanding Notes represented thereby will be made by the Trustee or the Custodian, at the direction

of the Trustee, in accordance with instructions given by the Holder thereof as required by Section 2.06 hereof.

Global Notes. Notes offered and sold in reliance on Regulation S will be issued initially in the form of the Regulation S Temporary

Global Note, which will be deposited on behalf of the purchasers of the Notes represented thereby with the Trustee, as custodian for the

Depositary, and registered in the name of the Depositary or the nominee of the Depositary for the accounts of designated agents holding

Securities Act and who will take delivery of a beneficial ownership interest in a 144A Global Note bearing a Private Placement Legend,

all as contemplated by Section 2.06(b) hereof).

Following the termination of the Restricted Period,

the Company shall instruct, which instructions shall be in writing and comply with Rule 903(b)(3)(ii)(B) of Regulation S, the

of such beneficial interests and in accordance with Section 2.06(g), the Trustee will (i) reduce and endorse the Regulation

S Temporary Global Note accordingly and (ii) increase and endorse the Regulation S Permanent Global Note accordingly. The aggregate

principal amount of the Regulation S Temporary Global Note and the Regulation S Permanent Global Note may from time to time be increased

or decreased by adjustments made on the records of the Trustee and the Depositary or its nominee, as the case may be, in connection with

transfers of interest as hereinafter provided.

(d)   Euroclear

and Clearstream Procedures Applicable. The provisions of the “Operating Procedures of the Euroclear System” and “Terms

and Conditions Governing Use of Euroclear” and the “General Terms and Conditions of Clearstream Banking” and “Customer

Company by manual or facsimile signature.

If an Officer whose signature is on a Note no longer

holds that office at the time a Note is authenticated, the Note will nevertheless be valid.

A Note will not be valid until authenticated by

the manual signature of the Trustee. The signature will be conclusive evidence that the Note has been authenticated under this Indenture.

The Trustee will, upon receipt of a written order

of the Company signed by an Officer of the Company (an “Authentication Order”), together with the other documents required

by Sections 12.03 and 12.04, authenticate Notes for original issue that may be validly issued under this Indenture, including any Additional

Notes. The aggregate principal amount of Notes outstanding at any time may not exceed the aggregate principal amount of Notes authorized

for issuance by the Company pursuant to one or more Authentication Orders, except as provided in Section 2.07 hereof.

The Trustee may appoint an authenticating agent

acceptable to the Company 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 Company.

Notes may be presented for registration of transfer or for exchange (“Registrar”) and an office or agency where Notes

Agent or Registrar without notice to any Holder. The Company will notify the Trustee in writing of the name and address of any Agent not

a party to this Indenture. If the Company fails to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall

Company (“DTC”) to act as Depositary with respect to the Global Notes.

Section 2.04          Paying

Agent to Hold Money in Trust.

The Company will require each Paying Agent other

than the Trustee to agree in writing that the Paying Agent will hold in trust for the benefit of Holders or the Trustee all money held

by the Paying Agent for the payment of principal, premium, if any, or interest on the Notes, and will notify the Trustee of any default

by the Company in making any such payment. While any such default continues, the Trustee may require a Paying Agent to pay all money held

by it to the Trustee. The Company at any time may require a Paying Agent to pay all money held by it to the Trustee. Upon payment over

to the Trustee, the Paying Agent (if other than the Company or a Subsidiary) will have no further liability for the money. If the Company

or a Subsidiary acts as Paying Agent, it will segregate and hold in a separate trust fund for the benefit of the Holders all money held

by it as Paying Agent. Upon any bankruptcy or reorganization proceedings relating to the Company, the Trustee will serve as Paying Agent

for the Notes.

as the Trustee may request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and

addresses of the Holders of Notes.

by a nominee of the Depositary to the Depositary or to another nominee of the Depositary, or by the Depositary or any such nominee to

a successor Depositary or a nominee of such successor Depositary. All Global Notes will be exchanged by the Company for Definitive Notes

if:

(1) the Company delivers to the

Trustee notice from the Depositary that it is unwilling or unable to continue to act as Depositary or that it is no longer a clearing

agency registered under the Exchange Act and, in either case, a successor Depositary is not appointed by the Company within 90 days;

(2) the Company, at its option but

subject to the Depositary’s requirements, notifies the Trustee in writing that it elects to cause the issuance of the Definitive

Notes; provided that in no event shall the Regulation S Temporary Global Note be exchanged by the Company for Definitive Notes

prior to (A) the expiration of the Restricted Period and (B) the receipt by the Registrar of any certificates required pursuant

to Rule 903(b)(3)(ii)(B) under the Securities Act; or

(3) there has occurred and is continuing

a Default or Event of Default with respect to the Notes, and the Depositary notifies the Trustee of its decision to exchange the Global

Notes for Definitive Notes.

Upon the occurrence of any of the preceding events

in (1), (2) or (3) above, Definitive Notes shall be issued in such names as the Depositary shall instruct the Trustee. Global

Notes also may be exchanged or replaced, in whole or in part, as provided in Sections 2.07 and 2.10 hereof. Every Note authenticated and

delivered in exchange for, or in lieu of, a Global Note or any portion thereof, pursuant to this Section 2.06 or Section 2.07

or 2.10 hereof, shall be authenticated and delivered in the form of, and shall be, a Global Note. A Global Note may not be exchanged for

Indirect Participants shall have no rights under this Indenture with respect to any Global Note held on their behalf by the Depositary

or by the Trustee as the Custodian with respect to the Global Notes, and the Company, the Trustee and any agent of the Company or the

Trustee shall be entitled to treat the Depositary as the absolute owner of such Global Note for all purposes whatsoever. Notwithstanding

the foregoing, nothing herein shall prevent the Company, the Trustee or any agent of the Company or the Trustee from giving effect to

any written certification, proxy or other authorization furnished by the Depositary or impair, as between the Depositary and its Participants

or the Indirect Participants, the operation of customary practices of such Depositary governing the exercise of the rights of a holder

of a beneficial interest in any Global Note. Subject to the provisions of this Section 2.06 and Section 12.14, the Holder of

a Global Note shall be entitled to grant proxies and otherwise authorize any Person, including Participants and Indirect Participants

and Persons that may hold interests through such Persons, to take any action that a Holder is entitled to take under this Indenture or

the Notes. Beneficial interests in the Restricted Global Notes will be subject to restrictions on transfer comparable to those set forth

(3) All Global Notes and Definitive

Notes issued upon any registration of transfer or exchange of Global Notes or Definitive Notes will be the valid obligations of the Company,

evidencing the same debt, and entitled to the same benefits under this Indenture, as the Global Notes or Definitive Notes surrendered

upon such registration of transfer or exchange. The transferor shall also provide or cause to be provided to the Trustee all information

necessary to allow the Trustee to comply with any applicable tax reporting obligations, including without limitation, any cost basis reporting

obligations under Internal Revenue Code Section 6045. The Trustee may rely on any such information provided to it and shall have

no responsibility to verify or ensure the accuracy of such information.

(4) Neither the Registrar nor the

Company will be required:

(A)   to

issue, to register the transfer of or to exchange any Notes during a period beginning at the opening of business 15 days before the day

of any selection of Notes for redemption under Section 3.02 hereof and ending at the close of business on the day of selection;

(B)   to

register the transfer of or to exchange any Note selected for redemption in whole or in part, except the unredeemed portion of any Note

being redeemed in part; or

(5) Prior to due presentment for

the registration of a transfer of any Note, the Trustee, any Agent and the Company may deem and treat the Person in whose name any Note

is registered as the absolute owner of such Note for the purpose of receiving payment of principal of and interest on such Notes and for

all other purposes, and none of the Trustee, any Agent or the Company shall be affected by notice to the contrary.

(6) The Trustee will authenticate

Global Notes and Definitive Notes in accordance with the provisions of Section 2.02 hereof.

(7) All certifications, certificates

and Opinions of Counsel required to be submitted to the Registrar pursuant to this Section 2.06 to effect a registration of transfer

or exchange may be submitted by facsimile.

(8) Neither the Trustee nor the

Registrar shall have any 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 Participants or beneficial owners of interests in any Definitive Note or 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.

Section 2.07          Replacement

Notes.

If any mutilated Note is surrendered to the Trustee

or the Company and the Trustee receives evidence to its satisfaction of the destruction, loss or theft of any Note, the Company will issue

and the Trustee, upon receipt of an Authentication Order, will authenticate a replacement Note if the Trustee’s requirements are

met. If required by the Trustee or the Company, an indemnity bond must be supplied by the Holder that is sufficient in the judgment of

the Trustee and the Company to protect the Company, the Trustee, any Agent and any authenticating agent from any loss that any of them

may suffer if a Note is replaced. The Company may charge for its expenses in replacing a Note.

Every replacement Note is an additional obligation

of the Company and will be entitled to all of the benefits of this Indenture equally and proportionately with all other Notes duly issued

hereunder.

Section 2.08          Outstanding

Notes.

The Notes outstanding at any time are all the Notes

authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in the interest

in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this Section 2.08 as not

outstanding. Except as set forth in Section 2.09 hereof, a Note does not cease to be outstanding because the Company or an Affiliate

of the Company holds the Note; however, Notes held by the Company or a Subsidiary of the Company shall not be deemed to be outstanding

for purposes of Section 3.07(a) hereof.

If a Note is replaced pursuant to Section 2.07

hereof, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Note is held by a protected

purchaser.

If the principal amount of any Note is considered

paid under Section 4.01 hereof, it ceases to be outstanding and interest on it ceases to accrue.

If the Paying Agent (other than the Company, a

Subsidiary or an Affiliate of any thereof) holds, by 11:00 a.m., Eastern Time, on a Redemption Date or other maturity date, money sufficient

to pay Notes payable on that date, then on and after that date such Notes will be deemed to be no longer outstanding and will cease to

accrue interest.

Section 2.09          Treasury

Notes.

In determining whether the Holders of the required

principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Company or any Guarantor, or by any Person

directly or indirectly controlling or controlled by or under direct or indirect common control with the Company or any Guarantor, will

be considered as though not outstanding, except that for the purposes of determining whether the Trustee will be protected in relying

on any such direction, waiver or consent, only Notes that a Responsible Officer of the Trustee actually knows are so owned will be so

disregarded.

Section 2.10          Temporary

Notes.

Until certificates representing Notes are ready

for delivery, the Company may prepare and the Trustee, upon receipt of an Authentication Order, together with the other documents required

by Sections 12.03 and 12.04, will authenticate temporary Notes. Temporary Notes will be substantially in the form of certificated Notes

but may have variations that the Company considers appropriate for temporary Notes and as may be reasonably acceptable to the Trustee.

Without unreasonable delay, the Company will prepare and the Trustee will authenticate definitive Notes in exchange for temporary Notes.

Holders of temporary Notes will be entitled to

all of the benefits of this Indenture.

Section 2.11          Cancellation.

The Company at any time may deliver Notes to the

Trustee for cancellation. The Registrar and Paying Agent will forward to the Trustee any Notes surrendered to them for registration of

transfer, exchange or payment. The Trustee and no one else will cancel all Notes surrendered for registration of transfer, exchange, payment,

replacement or cancellation and will destroy canceled Notes in accordance with the Trustee’s policy then in effect (subject to the

record retention requirement of the Exchange Act). Certification of the destruction of all canceled Notes will be delivered to the Company

upon written request. The Company may not issue new Notes to replace Notes that it has paid or that have been delivered to the Trustee

for cancellation.

Section 2.12          Defaulted

Interest.

If the Company defaults in a payment of interest

on the Notes, it will pay the defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest,

to the Persons who are Holders on a subsequent special record date, in each case at the rate provided in the Notes and in Section 4.01

hereof, provided that no special record date shall be required with respect to a payment of interest that is made within the applicable

grace period. The Company will 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. The Company will fix or cause to be fixed each such special record date and payment date; provided

that no such special record date may be less than 10 days prior to the related payment date for such defaulted interest. At least

15 days before the special record date, the Company (or, upon the written request of the Company, the Trustee in the name and at the expense

of the Company) will send or cause to be sent to Holders a notice that states the special record date, the related payment date and the

amount of such interest to be paid. The Trustee will not at any time be under any duty or responsibility to any Holder of Notes to determine

defaulted interest, or with respect to the nature, extent, or calculation of the amount of defaulted interest owed, or with respect to

the method employed in such calculation of defaulted interest.

Section 2.13          Trustee,

Paying Agent, Registrar Not Responsible for Depositary.

None of the Trustee, any Paying Agent or the Registrar

shall have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership

interests in any Global Note or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests.

The Trustee, any Paying Agent and the Registrar shall be entitled to deal with any Depositary, and any nominee thereof, that is the Holder

of any Global Note for all purposes of this Indenture relating to such Global Note (including the payment of principal, premium, if any,

and interest, the giving of instructions or directions by or to the owner or holder of a beneficial ownership interest in such Global

Note) as the sole Holder of such Global Note and shall have no obligations to the beneficial owners thereof. None of the Trustee, any

Paying Agent or the Registrar shall have any responsibility or liability for any acts or omissions of any Depositary with respect to any

Global Notes, for the records of any Depositary, including records in respect of beneficial ownership interests in respect of any Global

Note, for any transactions between such Depositary and any participant in such Depositary or between or among any such Depositary, any

such participant or any holder or owner of a beneficial interest in any Global Note or for any transfers of beneficial interests in any

Global Note.

ARTICLE 3

REDEMPTION AND PREPAYMENT

Section 3.01          Notices

to Trustee.

If the Company elects to redeem Notes pursuant

to the optional redemption provisions of Section 3.07 hereof, it must furnish to the Trustee, at least five Business Days (unless

a shorter period is satisfactory to the Trustee) before a notice of such redemption is to be given pursuant to Section 3.03, an Officer’s

Certificate setting forth:

(1)   the clause of this Indenture

pursuant to which the redemption shall occur;

(2)   the Redemption Date;

(3) the principal amount of Notes

to be redeemed; and

(4) the redemption price (if then

determinable and otherwise the method of determination).

Section 3.02          Selection

of Notes to Be Redeemed.

If less than all of the Notes are to be redeemed

at any time, the Trustee will select Notes for redemption as follows:

(1)  if

the Notes are listed on any national securities exchange, in compliance with the requirements of the principal national securities exchange

on which the Notes are listed; or

(2) if the Notes are not listed on any national securities exchange, on a pro rata basis;

and if the Notes are in global form, all in accordance

with the procedures of the Depositary.

No Notes of $2,000 or less can be redeemed in part.

In the event of partial redemption, the particular Notes to be redeemed will be selected prior to the redemption by the Trustee from the

outstanding Notes not previously called for redemption.

The Trustee will promptly notify the Company in

writing of the Notes selected for redemption and, in the case of any Note selected for partial redemption, the principal amount thereof

to be redeemed. Notes and portions of Notes selected will be in amounts of $2,000 or whole multiples of $1,000 in excess thereof; except

that if all of the Notes of a Holder are to be redeemed, the entire outstanding amount of Notes held by such Holder, even if not a multiple

of $1,000, shall be redeemed. Except as provided in the preceding sentence, provisions of this Indenture that apply to Notes called for

redemption also apply to portions of Notes called for redemption.

The Company will promptly notify the Trustee in

writing of any listing or delisting of the Notes on or from a national securities exchange.

Section 3.03          Notice

of Redemption.

At least 10 days (other than in connection with

a Special Mandatory Redemption, which shall be given pursuant to Section 3.08) but not more than 60 days before a Redemption Date,

the Company will mail or cause to be mailed, by first class mail (or sent electronically in the case of notices to DTC) a notice of optional

redemption to each Holder whose Notes are to be redeemed at its registered address, except that redemption notices may be given 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 pursuant to Article 8 or 11 hereof. Notice of any redemption of the Notes may, at the Company’s discretion,

be subject to one or more conditions precedent. In addition, if such redemption is subject to satisfaction of one or more conditions precedent,

such notice shall describe such conditions and state that, in the Company’s discretion, the Redemption Date may be delayed until

such time (including more than 60 days after the date the notice of redemption was delivered) as any or all such conditions shall be satisfied,

or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied

by the Redemption Date, or by the Redemption Date so delayed, or such notice may be rescinded at any time in the Company’s discretion

if in the good faith judgment of the Company any or all of such conditions will not be satisfied. The Company shall provide written notice

to the Trustee no later than the Redemption Date, by 11:00 a.m., Eastern Time, that all conditions to the redemption have been satisfied

or if any such redemption has been rescinded or delayed, and upon receipt the Trustee shall provide such notice to each Holder of Notes

in the same manner in which the redemption notice was given.

The notice will identify the Notes to be redeemed

and will state:

(1) the Redemption Date;

(2) the redemption price, if then

determinable and, if not, the manner of its determination;

(3) if any Note is being redeemed

in part, the portion of the principal amount of such Note to be redeemed and that, after the Redemption Date upon surrender of such Note,

a new Note or Notes in principal amount equal to the unredeemed portion will be issued in the name of the Holder thereof upon cancellation

of the original Note;

(4) the name and address of the

Paying Agent;

(5) that Notes called for redemption

must be surrendered to the Paying Agent to collect the redemption price;

(6) that, unless the Company defaults

in making such redemption payment, interest on Notes called for redemption ceases to accrue on and after the Redemption Date;

(7) the paragraph of the Notes and/or

Section of this Indenture pursuant to which the Notes called for redemption are being redeemed;

(8) any condition precedent to the

redemption; and

(9) that no representation is made

as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Notes.

At the Company’s request, the Trustee will

give the notice of redemption in the Company’s name and at its expense; provided, however, that the Company has delivered

to the Trustee an Officer’s Certificate in accordance with Section 3.01 requesting that the Trustee give such notice and a

form of the notice of redemption setting forth the information specified in the preceding paragraph.

Section 3.04          Effect

of Notice of Redemption.

Once notice of redemption is given in accordance

with Section 3.03 hereof, Notes called for redemption without condition will become irrevocably due and payable on the Redemption

Date at the redemption price.

Section 3.05          Deposit

of Redemption Price.

Prior to 11:00 a.m., Eastern Time, on the Redemption

Date, the Company will deposit with the Trustee or with the Paying Agent money sufficient (as determined by the Company) to pay the redemption

price of and accrued interest on all Notes to be redeemed on that date. The Trustee or the Paying Agent will promptly return to the Company

any money deposited with the Trustee or the Paying Agent by the Company in excess of the amounts necessary to pay the redemption price

of, and accrued interest on all Notes to be redeemed.

If the Company complies with the provisions of

the preceding paragraph, on and after the Redemption Date, interest will cease to accrue on the Notes or the portions of Notes called

for redemption. If a Note is redeemed on or after an interest record date but on or prior to the related interest payment date, then any

accrued and unpaid interest shall be paid to the Person in whose name such Note was registered at the close of business on such record

date. If any Note called for redemption is not so paid upon surrender for redemption because of the failure of the Company to comply with

the preceding paragraph, interest shall be paid on the unpaid principal, from the Redemption Date until such principal is paid, and to

the extent lawful on any interest not paid on such unpaid principal, in each case at the rate then in effect as provided in the Notes

and in Section 4.01 hereof.

Section 3.06          Notes

Redeemed in Part.

Upon surrender of a Note that is redeemed in part,

the Company will issue and, upon receipt of an Authentication Order, the Trustee will authenticate for the Holder, at the expense of the

Company, a new Note equal in principal amount to the unredeemed portion of the Note surrendered.

Section 3.07          Optional

Redemption.

(a)   At

any time prior to November 1, 2029, the Company may on any one or more occasions redeem up to 40% of the aggregate principal amount

of Notes (including any Additional Notes) issued under this Indenture, upon prior notice in accordance with Section 3.03 hereof at

a redemption price of 107.625% of the principal amount, plus accrued and unpaid interest, if any, to, but excluding, the Redemption Date

(subject to the right of Holders of Notes on the relevant record date to receive interest due on an interest payment date that is on or

prior to the Redemption Date), with an amount of cash not greater than the net cash proceeds of one or more Equity Offerings; provided

that:

(1) at least 50% of the aggregate

principal amount of Notes issued under this Indenture on the Issue Date (excluding Notes held by the Company and its Subsidiaries) remains

outstanding immediately after the occurrence of such redemption; and

(2) the redemption occurs within

180 days of the date of the closing of such Equity Offering.

(b)   Except

pursuant to Section 3.07(a), Section 3.07(d), and Section 3.07(e) hereof, the Notes will not be redeemable at the

Company’s option prior to November 1, 2029.

or after November 1, 2029, the Company may redeem all or a part of the Notes, upon prior notice in accordance with Section 3.03

hereof, at the redemption prices (expressed as percentages of principal amount) set forth below plus accrued and unpaid interest, if any,

on the Notes redeemed to, but excluding, the applicable Redemption Date, if redeemed during the twelve-month period beginning on November 1

of each year indicated below, subject to the rights of Holders of Notes on the relevant record date to receive interest due on an interest

payment date that is on or prior to the Redemption Date:

Percentage

103.813 %

2030

101.906 %

2031 and thereafter

100.000 %

(d)   At

any time prior to November 1, 2029, the Company may also redeem all or a part of the Notes, upon prior notice in accordance with

Section 3.03 hereof, at a redemption price equal to 100% of the principal amount of Notes redeemed plus the Applicable Premium calculated

as of the Redemption Date, plus accrued and unpaid interest, if any, to, but excluding, the Redemption Date, subject to the rights of

Holders on the relevant record date to receive interest due on an interest payment date that is on or prior to the Redemption Date. The

notice need not set forth the Applicable Premium but only the manner of calculation of the redemption price. With respect to any redemption

pursuant to this Section 3.07(d), the Company will prior to such Redemption Date file with the Trustee an Officer’s Certificate

setting forth the Applicable Premium and the Treasury Rate and showing the calculation of each in reasonable detail. The Trustee shall

not be responsible for any such calculation.

(e)   In

the event that Holders of not less than 90% of the aggregate principal amount of the outstanding Notes tender and do not withdraw such

Notes in a Change of Control Offer or Alternate Offer (each as defined below in Section 4.13) or any other tender offer and the Company

(or the third party making the Change of Control Offer, Alternate Offer or other tender offer) purchases all of the Notes validly tendered

and not withdrawn by such Holders, the Company will have the right, upon not less than 10 nor more than 60 days’ prior notice, given

not more than 30 days following the purchase pursuant to the Change of Control Offer, Alternate Offer, or tender offer described above,

to redeem all of the Notes that remain outstanding following such purchase at a redemption price equal to the applicable tender offer

price in such Change of Control Offer, Alternate Offer or other tender offer (exclusive of any early tender premium, consent fee or other

fee or payment not conditioned solely upon participation in such tender or redemption), plus, without duplication, accrued and unpaid

interest on the Notes that remain outstanding to, but excluding, the Redemption Date (subject to the right of Holders of record on the

relevant record date to receive interest due on an interest payment date that is on or prior to the Redemption Date).

(f)   Any

redemption pursuant to this Section 3.07 shall be made pursuant to the provisions of Sections 3.01 through 3.06 hereof.

Section 3.08          Special

Mandatory Redemption.

If (x) the consummation of the Pilot Water

Acquisition does not occur on or before March 1, 2027 (or such later date as the Outside Date under the Acquisition Agreement shall

be extended by agreement of the parties thereto) (the “Outside Date”) or (y) prior thereto, the Company notifies

the Trustee in writing that the Acquisition Agreement has been terminated without the closing occurring thereunder or that the Company

will not pursue the consummation of the Pilot Water Acquisition (the earlier of the date of delivery of such notice described in clause

(y) and the Outside Date, the “Special Mandatory Redemption Trigger Date”), the Company will be required to redeem

an aggregate principal amount of the Notes equal to the excess, if any, of (i) the aggregate principal amount of the Notes issued

on the Issue Date over (ii) $450.0 million (such redemption, the “Special Mandatory Redemption”) at a redemption

price equal to the issue price of the Notes to be redeemed plus accrued and unpaid interest to, but excluding, the Special Mandatory Redemption

Date (as defined below) (the “Special Mandatory Redemption Price”).

As used herein, the “Pilot Water Acquisition”

means the closing of the acquisition of the outstanding membership interests of Pilot Water Solutions LLC, pursuant to the Acquisition

Agreement, and the “Acquisition Agreement” means the Membership Interest Purchase Agreement, dated as of September 24,

2026, by and among Pilot OFS Holdings LLC and Minerva Infrastructure LLC, as sellers, Select Water Solutions, LLC, as buyer, Pilot Travel

Centers LLC, as seller parent for limited purposes, and Pilot OFS Holdings LLC in its capacity as the sellers’ representative, as

amended from time to time.

In the event that the Company becomes obligated

to redeem Notes pursuant to the Special Mandatory Redemption, the Company will promptly, and in any event not more than 10 Business Days

after the Special Mandatory Redemption Trigger Date, deliver notice to the Trustee of the Special Mandatory Redemption and the date upon

which such Notes will be redeemed (the “Special Mandatory Redemption Date,” which date shall be no earlier than the

third Business Day following the date of such notice or later than the tenth Business Day following the date of such notice) together

with a notice of Special Mandatory Redemption and written instructions to the Trustee instructing the Trustee to deliver such notice to

each registered Holder of Notes to be redeemed (which instructions must be delivered to the Trustee at least two Business Days prior to

the date such notice of redemption is to be sent). The Trustee will then promptly mail (or in the case of Notes issued in global form,

deliver electronically in accordance with DTC procedures), such notice of Special Mandatory Redemption to each registered Holder of Notes

to be redeemed at its registered address. Unless the Company defaults in payment of the Special Mandatory Redemption Price, on and after

such Special Mandatory Redemption Date, interest will cease to accrue on the Notes to be redeemed.

Section 3.09          Mandatory

Redemption.

Except as described above in Section 3.08,

the Company is not required to make mandatory redemption or sinking fund payments with respect to the Notes. The Company is not prohibited

from acquiring the Notes by means other than a redemption, whether pursuant to tender offers, open market purchases or otherwise.

Section 3.10          Offer

to Purchase by Application of Excess Proceeds.

In the event that, pursuant to Section 4.10

hereof, the Company is required to commence an offer to all Holders to purchase Notes (an “Asset Sale Offer”), it will

follow the procedures specified below.

The Asset Sale Offer shall be made to all Holders

and all holders of other Indebtedness that is pari passu with the Notes containing provisions similar to those set forth in this

Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets. The Asset Sale Offer will remain open for

a period of at least 20 Business Days following its commencement and not more than 30 Business Days, except to the extent that a longer

period is required by applicable law (the “Offer Period”). No later than three Business Days after the termination

of the Offer Period (the “Purchase Date”), the Company will apply all Excess Proceeds (the “Offer Amount”)

to the purchase of Notes and such other pari passu Indebtedness (on a pro rata basis, if applicable) or, if less than the

Offer Amount has been tendered, all Notes and other Indebtedness tendered in response to the Asset Sale Offer. Payment for any Notes so

purchased will be made in the same manner as interest payments are made.

If the Purchase Date is on or after an interest

record date and on or before the related interest payment date, any accrued and unpaid interest will be paid to the Person in whose name

a Note is registered at the close of business on such record date, and no additional interest will be payable to Holders who tender Notes

pursuant to the Asset Sale Offer.

Upon the commencement of an Asset Sale Offer, the

Company will send, in the manner prescribed in Section 12.02, a notice to the Trustee and each of the Holders. The notice will contain

all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Asset Sale Offer. The notice, which will

govern the terms of the Asset Sale Offer, will state:

(1) that the Asset Sale Offer is

being made pursuant to this Section 3.10 and Section 4.10 hereof and the length of time the Asset Sale Offer will remain open;

(2) the Offer Amount, the purchase

price and the Purchase Date;

(3) that any Note not tendered or

accepted for payment will continue to accrue interest;

(4) that, unless the Company defaults

in making such payment, any Note accepted for payment pursuant to the Asset Sale Offer will cease to accrue interest after the Purchase

Date;

(5) that Holders electing to have

a Note purchased pursuant to an Asset Sale Offer may elect to have Notes purchased in integral multiples of $1,000 only;

(6) that Holders electing to have

Notes purchased pursuant to any Asset Sale Offer will be required to surrender the Note, with the form entitled “Option of Holder

to Elect Purchase” attached to the Notes completed, or transfer by book-entry transfer, to the Company, a Depositary, if appointed

by the Company, or a Paying Agent at the address specified in the notice at least three days before the Purchase Date;

(7) that Holders will be entitled

to withdraw their election if the Company, the depositary for the Asset Sale Offer or the Paying Agent, as the case may be, receives,

not later than the expiration of the Offer Period, a telegram, telex, electronic image scan, facsimile transmission or letter setting

forth the name of the Holder, the principal amount of the Note the Holder delivered for purchase and a statement that such Holder is withdrawing

his election to have such Note purchased;

(8) that, if the aggregate principal

amount of Notes and other pari passu Indebtedness surrendered by holders thereof exceeds the Offer Amount, the Notes and other

pari passu Indebtedness to be purchased will be selected on a pro rata basis based on the principal amount of Notes and

such other pari passu Indebtedness surrendered (with such adjustments as may be deemed appropriate by the Company so that only

Notes in denominations of $2,000, or integral multiples of $1,000 in excess thereof, will be purchased); and

(9) that Holders whose Notes were

purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered (or transferred

by book-entry transfer).

On or before the Purchase Date, the Company will,

to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Offer Amount of Notes or portions thereof

tendered pursuant to the Asset Sale Offer, or if less than the Offer Amount has been tendered, all Notes tendered, and will deliver or

cause to be delivered to the Trustee the Notes properly accepted together with an Officer’s Certificate stating that such Notes

or portions thereof were accepted for payment by the Company in accordance with the terms of this Section 3.10. The Company, the

depositary for the Asset Sale Offer or the Paying Agent, as the case may be, will promptly (but in any case not later than five days after

the Purchase Date) mail or deliver to each tendering Holder an amount equal to the purchase price of the Notes tendered by such Holder

and accepted by the Company for purchase, and the Company will promptly issue a new Note, and the Trustee, upon written request from the

Company, will authenticate and mail or deliver (or cause to be transferred by book entry) such new Note to such Holder, in a principal

amount equal to any unpurchased portion of the Note surrendered. Any Note not so accepted shall be promptly mailed or delivered by the

Company to the Holder thereof. The Company will publicly announce the results of the Asset Sale Offer on the Purchase Date.

ARTICLE 4

COVENANTS

Section 4.01          Payment

of Notes.

The Company will pay or cause to be paid the principal

of, premium, if any, and interest on the Notes on the dates and in the manner provided in the Notes. Principal, premium, if any, and interest

will be considered paid on the date due if the Paying Agent, if other than the Company or a Subsidiary thereof, holds as of 11:00 a.m. Eastern

Time on the due date money deposited by the Company in immediately available funds and designated for and sufficient to pay all principal,

premium, if any, and interest then due. With respect to physical certificates, presentation is due at maturity.

The Company shall pay interest on overdue principal,

and it shall pay interest on overdue installments of interest, at the rate then prevailing on the Notes to the extent lawful.

Notwithstanding anything to the contrary contained

in this Indenture, the Company may, to the extent required to do so by law, deduct or withhold income or other similar taxes imposed by

the United States of America from principal or interest payments hereunder.

Section 4.02          Maintenance

of Office or Agency.

The Company will maintain an office or agency (which

may be an office of the Trustee or an affiliate of the Trustee, Registrar or co-registrar) where Notes may be surrendered for registration

of transfer or for exchange and where notices and demands to or upon the Company in respect of the Notes and this Indenture may be served.

The Company will give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency.

If at any time the Company fails to maintain any such required office or agency or fails to furnish the Trustee with the address thereof,

such presentations, surrenders, notices and demands (not including service of process) may be made or served at the Corporate Trust Office

of the Trustee.

The Company 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 such designations; provided, however, that no such designation or rescission will in any manner relieve the

Company of its obligation to maintain an office or agency for such purposes. The Company will give prompt written notice to the Trustee

of any such designation or rescission and of any change in the location of any such other office or agency.

The Company hereby designates the Corporate Trust

Office of the Trustee as one such office or agency of the Company in accordance with Section 2.03 hereof.

Analysis of Financial Condition and Results of Operations” and, with respect to the annual information only, a report on the annual

financial statements by the Parent’s certified independent accountants; and

(2) all information containing substantially

the same information that would be required to be filed with the SEC on Form 8-K if the Parent were required to file such reports

under Items 1.01 (Entry into a Material Definitive Agreement); 1.03 (Bankruptcy or Receivership); 2.01 (Completion of Acquisition

or Disposition of Assets); 2.03 (Creation of a Direct Financial Obligation or an Obligation under an Off-Balance Sheet Arrangement

of a Registrant); 2.04 (Triggering Events that Accelerate or Increase a Direct Financial Obligation or an Obligation under an Off-Balance

Sheet Arrangement); 4.02 (Non-Reliance on Previously Issued Financial Statements or a Related Audit Report or Completed Interim Review);

5.01 (Changes in Control of Registrant); 5.02(a)(1) (Resignation of Director due to Disagreement with Registrant); and

5.02(c)(1) (Name and Position of Newly Appointed Officer and Date of Appointment). The availability of the foregoing information

or reports on the SEC’s website will be deemed to satisfy the foregoing delivery requirements.

(b)   Notwithstanding

the foregoing, the financial statements, information and other documents required to be provided as described in Section 4.03(a) may

be those of (i) the Company or (ii) any direct or indirect parent of the Company or the Parent; provided that in the

case of clause (ii), if and so long as such parent has Independent Assets or Operations, the same is accompanied by consolidating information

(which need not be audited) that explains in reasonable detail the differences between the information relating to such parent, on the

one hand, and the information relating to the Parent and its Restricted Subsidiaries on a stand-alone basis, on the other hand.

the avoidance of doubt, (1) such information provided pursuant to Section 4.03(a) will not be required to contain the separate

financial information required by Rule 3-09, Rule 3-10 or Rule 3-16 of Regulation S-X or any schedules required by Regulation

S-X, or in each case any successor provisions, (2) such information shall not be required to comply with Regulation G under the Exchange

Act or Item 10(e) of Regulation S-K with respect to any non-GAAP financial measures contained therein and (3) such information

will not be required to comply with Section 302 or Section 404 of the Sarbanes-Oxley Act of 2002, or related Items 307 or 308

of Regulation S-K.

(d)   If

the Company 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 Company, then the annual and quarterly

information required by Section 4.03(a) 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 Company and its Restricted Subsidiaries

separate from the financial condition and results of operations of such Unrestricted Subsidiaries.

(e)   Any

and all Defaults or Events of Default arising from a failure to furnish in a timely manner any information required by this Section 4.03

shall be deemed cured (and the Company shall be deemed to be in compliance with this Section 4.03) upon furnishing such information

as contemplated by this Section 4.03 (but without regard to the date on which such information or report is so furnished); provided

that such cure shall not otherwise affect the rights of the Holders under Article 6 if the principal of, premium, if any, on,

and interest, if any, on, the Notes have been accelerated in accordance with the terms of this Indenture and such acceleration has not

been rescinded or cancelled prior to such cure.

(f)   So

long as any Notes are outstanding, the Company will also maintain a website to which Holders, bona fide prospective investors, bona fide

market makers in the Notes affiliated with any Initial Purchaser and bona fide securities analysts (to the extent providing analysis of

investment in the Notes) are given access (which may be password protected) and to which all of the reports required by this Section 4.03

are posted within 15 days after the time the Company would be required to provide such information pursuant to Section 4.03(a), unless

they are otherwise publicly available on the SEC’s EDGAR filing system (or any successor filing system).

(g)   The

Company shall furnish to Holders, prospective investors, broker-dealers and securities analysts, upon their request, any 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.

(h)   Delivery

of reports, information and documents to the Trustee under this Indenture is for information purposes only and the information and the

Trustee’s receipt of the foregoing shall not constitute actual or constructive knowledge or notice of any information contained

therein, or determinable from information contained therein, including the Company’s compliance with any of its covenants thereunder

(as to which the Trustee is entitled to rely exclusively on an Officer’s Certificate). The Trustee shall have no duty to monitor

or confirm, on a continuing basis or otherwise, the Company’s or any other person’s compliance with any of the covenants under

this Indenture, to determine whether such reports, information or documents are available on the SEC’s EDGAR filing system (or any

successor filing system), the Company’s website or otherwise, to examine such reports, information, documents and other reports

to ensure compliance with the provisions of this Indenture, to ascertain the correctness or otherwise of the information or the statements

contained therein or to participate in any conference calls.

Section 4.04          Compliance

Certificate.

(a)   The

Company and each Guarantor shall deliver to the Trustee, within 90 days after the end of each fiscal year ending after the Issue Date,

an Officer’s Certificate stating that a review of the activities of the Company and the Company’s Subsidiaries during the

preceding fiscal year has been made under the supervision of the signing Officers with a view to determining whether the Company has kept,

observed, performed and fulfilled its obligations under this Indenture, and further stating, as to each such Officer signing such certificate,

that to the best of his or her knowledge the Company has kept, observed, performed and fulfilled each and every covenant contained in

this Indenture and is not in default in the performance or observance of any of the terms, provisions and conditions of this Indenture

(or, if a Default or Event of Default has occurred, describing all such Defaults or Events of Default of which he or she may have knowledge

and what action the Company is taking or proposes to take with respect thereto).

(b)   So

long as any of the Notes are outstanding, the Company and the Guarantors will deliver to the Trustee, within five Business Days of an

Officer thereof becoming aware of any Default or Event of Default, an Officer’s Certificate specifying such Default or Event of

Default and what action the Company is taking or proposes to take with respect thereto.

The Trustee shall be entitled to conclusively rely

upon all of the Officer’s Certificates delivered under this Section 4.04 without any duty of further inquiry.

Section 4.05          Taxes.

The Company will pay, and will cause each of its

Restricted Subsidiaries to pay, prior to delinquency, all material taxes, assessments, and governmental levies except such as are contested

in good faith and by appropriate proceedings or where the failure to effect such payment is not adverse in any material respect to the

Holders of the Notes.

Section 4.06          Stay,

Extension and Usury Laws.

The Company and each of the Guarantors covenant

(to the extent that they may lawfully do so) that they will not at any time insist upon, plead, or in any manner whatsoever claim or take

the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect

the covenants or the performance of this Indenture; and the Company and each of the Guarantors (to the extent that they may lawfully do

so) hereby expressly waive all benefit or advantage of any such law, and covenant that they will not, by resort to any such law, 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 has been enacted.

Section 4.07          Restricted

Payments.

(a)   The

Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly:

(i)   declare

or pay any dividend or make any other payment or distribution on account of the Company’s or any of its Restricted Subsidiaries’

Equity Interests (including, without limitation, any payment in connection with any merger or consolidation involving the Company or any

of its Restricted Subsidiaries) or to the direct or indirect holders of the Company’s or any of its Restricted Subsidiaries’

Equity Interests in their capacity as such (other than distributions or dividends payable in Equity Interests of the Company (other than

Disqualified Equity or Designated Preferred Stock) and other than distributions or dividends payable to the Company or a Restricted Subsidiary);

(ii)   purchase,

redeem or otherwise acquire or retire for value (including without limitation, in connection with any merger or consolidation involving

the Company) any Equity Interests of the Company or any direct or indirect parent of the Company;

(iii)   make

any payment on or with respect to, or purchase, redeem, defease or otherwise acquire or retire for value any Indebtedness of the Company

or any Guarantor that is contractually subordinated to the Notes or to any Note Guarantee (excluding intercompany Indebtedness between

or among the Company and any of its Restricted Subsidiaries), except a payment of interest or principal within one year of the Stated

Maturity thereof; or

(iv)   make

any Restricted Investment (all such payments and other actions set forth in these clauses (i) through (iv) above being collectively

referred to as “Restricted Payments”), unless, at the time of and after giving effect to such Restricted Payment,

(1)   no

Payment Default or Event of Default (other than a Reporting Default) has occurred and is continuing or would occur as a consequence of

such Restricted Payment;

(2)   the

Company’s Fixed Charge Coverage Ratio for the most recently ended four full fiscal quarters for which internal financial statements

are available at the time of such Restricted Payment is not less than 2.00 to 1.00; and

(3)   such

Restricted Payment, together with the aggregate amount of all other Restricted Payments made by the Company and its Restricted Subsidiaries

since the Issue Date (excluding Restricted Payments permitted by Section 4.07(b)(2) through (15) and (17) but including any

Restricted Payments made under Section 4.07(b)(16) only to the extent that such Restricted Payments pursuant to Section 4.07(b)(16)

do not, at the time thereof, reduce the amount available for Restricted Payments under the following clauses (A) through (E) below

zero) is less than the sum, without duplication (the “Restricted Payments Basket”) of:

(A)   50%

of the Consolidated Net Income of the Company for the period (taken as one accounting period) from October 1, 2026 to the end of

the Company’s most recently ended fiscal quarter for which internal financial statements are available at the time of such Restricted

Payment; plus

(B)   100%

of the aggregate net cash proceeds received by the Company and the Fair Market Value of property or securities other than cash (including

Capital Stock of Persons engaged primarily in a Permitted Business) or long term assets that are used or useful in a Permitted Business

to the extent acquired as a contribution to its common equity capital or from the issue or sale of or in consideration of Equity Interests

of a Parent Company (other than Disqualified Equity, Designated Preferred Stock or Excluded Contributions), and solely to the extent the

proceeds thereof are contributed to the common equity capital of the Company, in each case, since the Issue Date, or from the issue or

sale of convertible or exchangeable Disqualified Equity, Designated Preferred Stock or convertible or exchangeable debt securities of

the Company that since the Issue Date have been converted into or exchanged for such Equity Interests or Equity Interests of a Parent

Company (other than Equity Interests (or Disqualified Equity, Designated Preferred Stock, Excluded Contributions or debt securities) sold

to a Restricted Subsidiary of the Company); plus

the extent that any Restricted Investment that was made after the Issue Date is sold for cash or Cash Equivalents or otherwise liquidated

or repaid for cash or Cash Equivalents (including any sale of Equity Interests of an Unrestricted Subsidiary), the return of capital or

similar payment made in cash or Cash Equivalents with respect to such Restricted Investment (less the cost of disposition, if any); plus

(D)   dividends,

repayments of loans or advances, or other transfers of assets in each case to the Company or any of its Restricted Subsidiaries from any

Person other than a Restricted Subsidiary (including, without limitation, Unrestricted Subsidiaries) or from redesignations of Unrestricted

Subsidiaries as Restricted Subsidiaries, to the extent such amounts have not been included in Consolidated Net Income for any period commencing

on or after the Issue Date; plus

(E)   any

dividends or distributions received in cash by the Company or a Restricted Subsidiary after the Issue Date from an Unrestricted Subsidiary

of the Company, to the extent that such dividends or distributions were not otherwise included in the Consolidated Net Income of the Company

for such period, provided, however, that this clause (E) shall exclude any amounts deemed to increase the aggregate amounts

available under Section 4.07(b)(17).

(b)   The

provisions of Section 4.07(a) hereof will not prohibit:

(1) the payment of any dividend

or distribution or the consummation of an irrevocable redemption of subordinated Indebtedness within 60 days after the date of the declaration

of such dividend or distribution, or the delivery of the irrevocable notice of redemption, as the case may be, if at the date of declaration

or the date on which such irrevocable notice is delivered, such dividend, distribution or redemption would have complied with the provisions

of this Indenture (assuming, in the case of a redemption payment, the giving of the notice of such redemption payment would have been

deemed to be a Restricted Payment at such time and such deemed Restricted Payment would have been permitted at such time);

(2) the making of any Restricted

Payment in exchange for, or out of the net cash proceeds of, a substantially concurrent (a) capital contribution to the Company from

any Person (other than a Restricted Subsidiary of the Company) or (b) sale (other than to a Restricted Subsidiary of the Company)

of Equity Interests of the Company (other than Disqualified Equity) or any direct or indirect parent, with a sale being deemed substantially

concurrent if such Restricted Payment occurs not more than 180 days after such sale;

(3) (a) the purchase, redemption,

defeasance or other acquisition or retirement for value of any subordinated Indebtedness of the Company or any Guarantor with the net

cash proceeds from an incurrence of, or in exchange for, Permitted Refinancing Indebtedness and (b) the prepayment, redemption, purchase,

defeasance or other satisfaction of any Indebtedness (1) existing at the time a Person becomes a Subsidiary or (2) assumed in

connection with the acquisition of assets, in each case, so long as such Indebtedness was not incurred in contemplation of such Person

becoming a Subsidiary or such asset acquisition (other than to the extent constituting refinancing indebtedness);

(4) the payment of any distribution

or dividend by a Restricted Subsidiary of the Company to the holders of its Equity Interests (other than Disqualified Equity) on a pro

rata basis or on a basis more favorable to the Company or a Restricted Subsidiary;

(5) so long as no Payment Default

or Event of Default (other than a Reporting Default) has occurred and is continuing or would be caused thereby, the repurchase, redemption

or other acquisition or retirement for value of any Equity Interests of the Company, any Restricted Subsidiary of the Company or any direct

or indirect parent thereof (including the Parent) held by any current or former officer, director, manager, consultant or employee of

the Company or any of the Company’s Restricted Subsidiaries or such direct or indirect parent pursuant to any equity subscription

agreement or plan, stock or unit option agreement, shareholders’ agreement, employment agreement or similar agreement; provided,

that the aggregate price paid for all such repurchased, redeemed, acquired or retired Equity Interests may not exceed $20.0 million in

any twelve-month period with any portion of such $20.0 million that is unused in any calendar year to be carried forward to successive

calendar years and added to such amount; provided further, that such amount in any twelve-month period may be increased by an amount

not to exceed (a) the cash proceeds received by the Company from the sale of Equity Interests of the Company to members of management,

employees, directors or managers of the Company or its Restricted Subsidiaries that occurs after the Issue Date (to the extent the cash

proceeds from the sale of such Equity Interests have not otherwise been applied to the payment of Restricted Payments by virtue of (3)(B) of

Section 4.07(a) hereof), plus (b) the cash proceeds of key man life insurance policies received by the Company after

the Issue Date, less (c) the amount of any Restricted Payments made pursuant to clauses (a) and (b) of this clause

(5);

(6) so long as no Payment Default

or Event of Default (other than a Reporting Default) has occurred and is continuing or would be caused thereby, payments of dividends

on Disqualified Equity or Designated Preferred Stock issued pursuant to Section 4.09 hereof;

(7) purchases or other acquisitions

of Capital Stock (a) deemed to occur upon exercise of stock or unit options, warrants or other convertible securities if such Capital

Stock represents a portion of the exercise price of such options, warrants or other convertible securities or (b) made in lieu of

withholding taxes resulting from any such exercise or in connection with vesting of restricted equity grants, performance share units

or similar compensatory equity awards;

(8) cash payments in lieu of the

issuance of fractional shares in connection with the exercise of warrants, options or other securities convertible into or exchangeable

for Capital Stock of the Company, or arising from stock or unit dividends, splits or business combinations;

(9) in connection with an acquisition

by the Company or any of its Restricted Subsidiaries, the return to the Company or any of its Restricted Subsidiaries of Equity Interests

of the Company or any of its Restricted Subsidiaries constituting a portion of the purchase consideration in settlement of indemnification

claims or pursuant to purchase price adjustments under the acquisition agreement;

(10) so long as no Payment Default

or Event of Default (other than a Reporting Default) has occurred and is continuing, the purchase, redemption, defeasance or other acquisition

or retirement for value of any subordinated Indebtedness pursuant to provisions similar to those in Section 4.10 or 4.13; provided

that all Notes validly tendered and not withdrawn by Holders in connection with a Change of Control Offer or Asset Sale Offer, as

applicable, have been purchased, redeemed, defeased or otherwise acquired or retired for value;

(11) distributions to any Parent Company

in an amount sufficient (including any pro rata distributions required to be paid to holders of Capital Stock of such Parent Company)

to permit Parent to pay quarterly dividends on its outstanding common stock in an amount not to exceed $0.10 per share (such amount to

be appropriately adjusted (upward or downward, as applicable) to reflect any stock split, reverse stock split, stock dividend or similar

transaction occurring after the Issue Date so that the aggregate amount of distributions permitted after such transaction is the same

as the amount permitted immediately prior to such transaction);

(12) Restricted Payments that are made

(a) in an amount that does not exceed the aggregate amount of Excluded Contributions received since the Issue Date or (b) without

duplication with clause (a), in an amount equal to the Net Proceeds from an Asset Sale in respect of property or assets acquired after

the Issue Date, if the acquisition of such property or assets was financed with Excluded Contributions received since the Issue Date;

(13) Permitted Tax Distributions;

(14) Permitted Payments to Parent;

(15) payments made in connection with

the Pilot Water Acquisition and the transactions relating thereto in accordance with the Acquisition Agreement;

(16) so long as no Event of Default has

occurred and is continuing or would be caused thereby, other Restricted Payments, if the Company’s Consolidated Leverage Ratio would

have been less than or equal to 4.0 to 1.0, determined on a pro forma basis after giving effect to any such Restricted Payment; and

(17) other Restricted Payments in an

aggregate amount not to exceed the greater of (a) $140.0 million and (b) 5.0% of Consolidated Net Tangible Assets at the time

made, plus, in the case of Restricted Payments constituting Investments made pursuant to this clause (17), an amount equal to any returns

(including dividends, interest, distributions, returns of principal, profits on sale, repayments, income and similar amounts) actually

received in respect of any such Restricted Payments constituting Investments; provided that if this clause (17) is utilized to

make a Restricted Investment, the amount deemed to be utilized under this clause (17) will be the amount of such Restricted Investment

at any time outstanding (with the fair market value of such Investment being measured at the time made and without giving effect to subsequent

changes in value, but subject to adjustment as set forth in the definition of “Investment”).

The amount of all Restricted Payments (other than

cash) will be the Fair Market Value on the date of the Restricted Payment of the asset(s) or securities proposed to be transferred

or issued by the Company or such Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment, except that the amount

of any noncash dividend or distribution paid in accordance with clause (1) of Section 4.07(b) hereof shall be the Fair

Market Value as of the date on which such dividend or distribution is declared. The Fair Market Value of any assets or securities that

are required to be valued by this Section 4.07 will be determined in the manner prescribed in the definition of that term. For the

purposes of determining compliance with this Section 4.07, in the event that a Restricted Payment meets the criteria of more than

one of the categories of Restricted Payments described in the preceding clauses (1) through (17) (other than clause (16)), or more

than one of the clauses described in the definition of “Permitted Investments,” the Company will be permitted to classify

(or reclassify in whole or in part in its sole discretion) such Restricted Payment or Investment (or portion thereof) among Section 4.07(a) and/or

the preceding clauses (1) through (17) (other than clause (16)) and/or one or more clauses contained in the definition of “Permitted

Investments,” in any manner that complies with this Section 4.07.

For the avoidance of doubt, this Section 4.07

will not restrict the making of any “AHYDO catch up payment” with respect to, and required by the terms of, any Indebtedness

of the Company or any Restricted Subsidiary permitted to be incurred under this Indenture.

Section 4.08          Dividend

and Other Payment Restrictions Affecting Subsidiaries.

(a)   The

Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create or permit to exist or become

effective any consensual encumbrance or restriction on the ability of any Restricted Subsidiary that is not a Guarantor to:

(1) pay dividends or make any other

distributions on its Equity Interests to the Company or any of its Restricted Subsidiaries, or pay any indebtedness owed to the Company

or any of its Restricted Subsidiaries; provided that priority of any preferred equity or similar Equity Interest in receiving dividends

or liquidating distributions prior to the payment of dividends or liquidating distributions on common equity shall not be deemed to be

a restriction on the ability to make distributions on Equity Interests;

(2) make loans or advances to the

Company or any of its other Restricted Subsidiaries; or

(3) sell, lease or otherwise transfer

any of its properties or assets to the Company or any of its other Restricted Subsidiaries.

(b)   The

restrictions in Section 4.08(a) hereof will not apply to encumbrances or restrictions existing under or by reason of:

(1) agreements as in effect on the

Issue Date and any amendments, restatements, modifications, renewals, supplements, refundings, replacements or refinancings of those agreements

or the Indebtedness to which they relate; provided that the amendments, restatements, modifications, renewals, supplements, refundings,

replacements or refinancings are not materially more restrictive, taken as a whole, with respect to such dividend, distribution and other

payment restrictions than those contained in those agreements on the Issue Date;

(2) the Credit Agreement, this Indenture,

the Notes and the Note Guarantees;

(3) agreements governing Indebtedness

permitted to be incurred under the provisions of the covenant described in Section 4.09 and any amendments, restatements, modifications,

renewals, supplements, refundings, replacements or refinancings of such agreements; provided that either (a) the restrictions

therein are not materially more restrictive, taken as a whole, than those contained in the Credit Agreement, this Indenture, the Notes

and the Note Guarantees or (b) are, in the judgment of the Company or any officer thereof, not reasonably likely to have a material

adverse effect on the ability of the Company to make required payments on the Notes;

(4) applicable law, rule, regulation

or order;

(5) any instrument governing Indebtedness

or Equity Interest of a Person acquired by the Company or any of its Restricted Subsidiaries as in effect at the time of such acquisition

(except to the extent such Indebtedness or Equity Interest was incurred in connection with or in contemplation of such acquisition, other

than refinancing indebtedness), which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person,

other than the Person, or the property or assets of the Person, so acquired; provided that, in the case of Indebtedness, such Indebtedness

was permitted by the terms of this Indenture to be incurred;

(6) customary non-assignment provisions

in transportation agreements or purchase and sale or exchange agreements, pipeline and water treatment agreements, or similar operational

agreements or in licenses or leases, in each case entered into in the ordinary course of business;

(7) purchase money obligations for

property acquired and Finance Lease Obligations that impose restrictions on the property purchased or leased of the nature described in

clause (3) of Section 4.08(a) hereof;

(8) any agreement (a) for the

sale or other disposition of a Restricted Subsidiary that contains any such restrictions on that Restricted Subsidiary pending its sale

or other disposition or (b) for the sale or other disposition of a particular asset or line of business of a Restricted Subsidiary

that imposes restrictions on assets subject to any agreement of the nature described in clause (3) of Section 4.08(a) hereof;

(9) Permitted Refinancing Indebtedness;

provided that the restrictions contained in the agreements governing such Permitted Refinancing Indebtedness are not materially

more restrictive, taken as a whole, than those contained in the agreements governing the Indebtedness being refinanced;

(10) Liens permitted to be incurred

under the provisions of Section 4.12 hereof that limit the right of the debtor to dispose of the assets subject to such Liens;

(11) provisions limiting the disposition

or distribution of assets or property in joint venture agreements, asset sale agreements, sale-leaseback agreements, stock sale agreements

and other similar agreements entered into in the ordinary course of business;

(12) any agreement or instrument relating

to any property or assets acquired after the Issue Date, so long as such encumbrance or restriction relates only to the property or assets

so acquired and is not and was not created in anticipation of such acquisitions (other than with respect to any refinancing indebtedness

or similar replacement agreements entered into in connection with applicable change of control provisions);

(13) restrictions on cash or other deposits

or net worth imposed by customers under contracts entered into in the ordinary course of business; and

(14) encumbrances or restrictions contained

in, or in respect of, Hedging Obligations permitted under this Indenture from time to time.

Section 4.09          Incurrence

of Indebtedness and Issuance of Disqualified Equity or Designated Preferred Stock.

(a)   The

Company will not, and will not permit any of its Restricted Subsidiaries to, directly or indirectly, create, incur, issue, assume, Guarantee

or otherwise become directly or indirectly liable, contingently or otherwise, with respect to (collectively, “incur”)

any Indebtedness (including Acquired Debt), and the Company will not issue any Disqualified Equity or Designated Preferred Stock and will

not permit any of its Restricted Subsidiaries to issue any Disqualified Equity or Designated Preferred Stock; provided, however,

that the Company and any Restricted Subsidiary may incur Indebtedness (including Acquired Debt) and the Company and the Restricted Subsidiaries

may issue Disqualified Equity or Designated Preferred Stock, if the Company’s Fixed Charge Coverage Ratio for the Reference Period

immediately preceding the date on which such additional Indebtedness is incurred or such Disqualified Equity or Designated Preferred Stock

is issued, as the case may be, would have been at least 2.0 to 1.0, determined on a pro forma basis (including a pro forma application

of the net proceeds therefrom), as if the additional Indebtedness had been incurred or the Disqualified Equity or Designated Preferred

Stock had been issued, as the case may be, at the beginning of such Reference Period.

(b)   The

provisions of Section 4.09(a) hereof will not prohibit the incurrence of any of the following items of Indebtedness (collectively,

“Permitted Debt”) or the issuance of any Disqualified Equity or Designated Preferred Stock:

(1) the incurrence by the Company

or any of its Restricted Subsidiaries of additional Indebtedness and letters of credit and the Guarantees thereof under Credit Facilities

in an aggregate principal amount at any one time outstanding under this clause (1) (with letters of credit being deemed to have a

principal amount equal to the maximum potential liability of the Company and its Restricted Subsidiaries thereunder), including all Permitted

Refinancing Indebtedness incurred to renew, refund, refinance, replace, defease or discharge any Indebtedness incurred pursuant to this

clause (1), not to exceed the greater of (a) $750.0 million and (b) 35.0% of Consolidated Net Tangible Assets (determined as

of the date of incurrence and after giving effect to the use of proceeds therefrom);

(2) the incurrence by the Company

and its Restricted Subsidiaries of any Existing Indebtedness or Disqualified Equity or Designated Preferred Stock;

(3) the incurrence by the Company

and the Guarantors of Indebtedness represented by the Notes and the related Note Guarantees issued on the Issue Date;

(4) the incurrence by the Company

or any of its Restricted Subsidiaries of Indebtedness represented by Finance Lease Obligations, mortgage financings or purchase money

obligations, in each case, incurred for the purpose of financing or refinancing all or any part of the purchase price or cost of construction

or improvement of property, plant or equipment used in the business of the Company or any of its Restricted Subsidiaries, in an aggregate

principal amount, including all Permitted Refinancing Indebtedness incurred to renew, refund, refinance, replace, defease or discharge

any Indebtedness incurred pursuant to this clause (4), at any time outstanding not to exceed the greater of (a) $175.0 million and

(b) 7.5% of Consolidated Net Tangible Assets (determined as of the date of incurrence and after giving effect to the use of proceeds

therefrom);

(5) the incurrence by the Company

or any of its Restricted Subsidiaries of Permitted Refinancing Indebtedness in exchange for, or the net proceeds of which are used to

renew, refund, refinance, replace, defease or discharge any Indebtedness (other than intercompany Indebtedness) that was permitted by

this Indenture to be incurred under Section 4.09(a) hereof or clause (2), (3), (4), (10), (13), or (15) of this Section 4.09(b) or

this clause (5);

(6) the incurrence by the Company

or any of its Restricted Subsidiaries of intercompany Indebtedness between or among the Company and any of its Restricted Subsidiaries;

provided, however, that:

(A)   if

the Company or any Guarantor is the obligor on such Indebtedness and the payee is not the Company or a Guarantor, such Indebtedness must

be unsecured and expressly subordinated to the prior payment in full in cash of all Obligations then due with respect to the Notes, in

the case of the Company, or the Note Guarantee, in the case of a Guarantor; and

(B)   (1) any

subsequent issuance or transfer of Equity Interests that results in any such Indebtedness being held by a Person other than the Company

or a Restricted Subsidiary of the Company and (2) any sale or other transfer of any such Indebtedness to a Person that is not either

the Company or a Restricted Subsidiary of the Company,

will be deemed, in each case, to constitute an incurrence

of such Indebtedness by the Company or such Restricted Subsidiary, as the case may be, that was not permitted by this clause (6);

(7) the incurrence by the Company

or any of its Restricted Subsidiaries of Hedging Obligations or Indebtedness under Treasury Management Arrangements;

(8) the Guarantee by the Company

or any of its Restricted Subsidiaries of (a) Indebtedness of the Company or a Restricted Subsidiary of the Company that was permitted

to be incurred by another provision of this Section 4.09 or (b) Indebtedness incurred by Joint Ventures, provided that

such Guarantee constitutes a Permitted Investment; and provided further, in each case, that if the Indebtedness being Guaranteed

is subordinated to or pari passu with the Notes or the Note Guarantees, then the Guarantee shall be subordinated or pari passu,

as applicable, to the same extent as the Indebtedness Guaranteed;

(9) the incurrence by the Company

or any of its Restricted Subsidiaries of Indebtedness in respect of workers’ compensation claims, health or other types of social

security benefits, unemployment or other insurance or self-insurance obligations, insurance contracts, reclamation, statutory obligations,

bankers’ acceptances, and performance, payment, appeal and surety bonds in the ordinary course of business, including Guarantees

and obligations respecting standby letters of credit supporting such obligations, to the extent not drawn (in each case other than an

obligation for money borrowed) and replacements of any of the foregoing;

(10) the incurrence by the Company

or any of its Restricted Subsidiaries of Permitted Acquisition Indebtedness;

(11) the issuance by the Company or any

of its Restricted Subsidiaries of Disqualified Equity or Designated Preferred Stock to the Company or any of its Restricted Subsidiaries,

as the case may be; provided, however, that:

(A)   any

subsequent issuance or transfer of Equity Interests of a Restricted Subsidiary that results in any such Disqualified Equity or Designated

Preferred Stock being held, directly or indirectly, by a Person other than the Company or a Restricted Subsidiary of the Company; and

(B)   any

sale or other transfer of any such Disqualified Equity or Designated Preferred Stock to a Person that is not either the Company or a Restricted

Subsidiary of the Company;

will be deemed, in each case, to constitute an issuance of

such Disqualified Equity or Designated Preferred Stock by the Company or such Restricted Subsidiary that was not permitted by this clause

(11);

(12) the incurrence in the ordinary course

of business by the Company or any of its Restricted Subsidiaries of Indebtedness under letters of credit incurred pursuant to a Credit

Facility, provided that such obligations are reimbursed within 30 days following the drawing of such letter of credit;

(13) the incurrence by the Company or

any of its Restricted Subsidiaries of liability in respect of the Indebtedness of any Unrestricted Subsidiary of the Company or any Joint

Venture but only to the extent that such liability is the result of the Company’s or any such Restricted Subsidiary’s being

a general partner of such Unrestricted Subsidiary or Joint Venture and not as guarantor of such Indebtedness and provided that,

after giving effect to any such incurrence, the aggregate principal amount of all Indebtedness incurred under this clause (13) and then

outstanding does not exceed $25.0 million;

(14) Indebtedness incurred on behalf

of, or guarantee obligations in respect of the Indebtedness of, joint ventures (regardless of the form of legal entity) that are not Subsidiaries

in an aggregate principal amount, when aggregated with the outstanding principal amount of Indebtedness then outstanding incurred pursuant

to this clause (14), not to exceed the greater of (a) $150.0 million and (b) 5.0% of Consolidated Net Tangible Assets (determined

as of the date of incurrence and after giving effect to the use of proceeds therefrom);

(15) Indebtedness Incurred or Disqualified

Equity or Designated Preferred Stock issued by the Company or any Restricted Subsidiary or Preferred Stock issued by any of its Restricted

Subsidiaries to the extent that the net proceeds thereof are promptly deposited with the Trustee to satisfy and discharge the Notes in

accordance with this Indenture; and

(16) the incurrence by the Company or

any of its Restricted Subsidiaries of additional Indebtedness or issuance of Disqualified Equity or Designated Preferred Stock in an aggregate

principal amount, including all Permitted Refinancing Indebtedness incurred to renew, refund, refinance, replace, defease or discharge

any Indebtedness incurred pursuant to this clause (16) at any time outstanding not to exceed the greater of (a) $130.0 million and

(b) 5.0% of Consolidated Net Tangible Assets (determined as of the date of incurrence and after giving effect to the use of proceeds

therefrom).

No Indebtedness shall be deemed to be contractually

subordinated in right of payment to any other Indebtedness of the Company or any such Guarantor solely by virtue of being unsecured or

by virtue of being secured on a first or junior Lien basis.

For purposes of determining compliance with this

Section 4.09, in the event that an item of proposed Indebtedness meets the criteria of more than one of the categories of Permitted

Debt described in clauses (1) through (16) above, or is entitled to be incurred pursuant to Section 4.09(a) hereof, the

Company will be permitted to classify such item of Indebtedness on the date of its incurrence, or later reclassify all or a portion of

such item of Indebtedness, in any manner that complies with this Section 4.09. Indebtedness under the Credit Agreement outstanding

on the date on which Notes are first issued and authenticated under this Indenture will initially be deemed to have been incurred on such

date in reliance on the exception provided by clause (1) of the definition of Permitted Debt.

The accrual of interest, the accretion or amortization

of original issue discount, the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms, the

reclassification of Preferred Stock as Indebtedness due to a change in accounting principles, and the payment of dividends on Disqualified

Equity or Designated Preferred Stock in the form of additional shares or units of the same class of Disqualified Equity or Designated

Preferred Stock will not be deemed to be an incurrence of Indebtedness or an issuance of Disqualified Equity or Designated Preferred Stock

for purposes of this Section 4.09; provided, in each such case, that the amount of any such accrual, accretion or payment

is included in Fixed Charges of the Company as accrued to the extent required by the definition of such term. Notwithstanding any other

provision of this Section 4.09, the maximum amount of Indebtedness that the Company or any Restricted Subsidiary may incur pursuant

to this Section 4.09 shall not be deemed to be exceeded solely as a result of fluctuations in exchange rates or currency values.

For purposes of calculating any ratio-based basket,

with respect to any revolving Indebtedness, delayed draw facility or other committed debt financing incurred under such ratio-based basket,

the Company may elect, at any time (which election may not be changed with respect to such Indebtedness), to either (x) give pro

forma effect to the incurrence of the entire committed amount of such Indebtedness, in which case such committed amount may thereafter

be borrowed or reborrowed, in whole or in part, from time to time, without further compliance with any ratio-based component of any provision

of this Indenture, or (y) give pro forma effect to the incurrence of the actual amount drawn under such revolving Indebtedness, delayed

draw facility or other committed debt financing, in which case, the ability to incur the amounts committed to under such Indebtedness

will be subject to the ratio-based basket (to the extent being incurred pursuant to such ratio) at the time of each such incurrence.

In the event an item of Indebtedness, Disqualified

Equity or Designated Preferred Stock (or any portion thereof) is incurred or issued pursuant to this Section 4.09(b) (other

than clause (10) above) on the same date that an item of Indebtedness, Disqualified Equity or Designated Preferred Stock (or

any portion thereof) is incurred or issued under Section 4.09(a) of this covenant or clause (10) above, then the Fixed

Charge Coverage Ratio will be calculated with respect to such incurrence or issuance under Section 4.09(a) or clause (10) above

without regard to any incurrence or issuance under Section 4.09(b) (other than with respect to any incurrence or issuance under

clause (10) above). Unless the Company elects otherwise, the incurrence or issuance of Indebtedness, Disqualified Equity or

Designated Preferred Stock will be deemed incurred or issued first under Section 4.09(a) or clause (10) to the extent

permitted, with the balance incurred or issued under Section 4.09(b) (other than pursuant to clause (10)) and any item

of Indebtedness, Disqualified Equity or Designated Preferred Stock incurred pursuant to Section 4.09(b) (other than pursuant

to clause (10)) will be automatically reclassified as incurred pursuant to Section 4.09(a). If any Indebtedness is incurred,

or Disqualified Equity or Designated Preferred Stock is issued, in reliance on a basket measured by reference to a percentage of the Company’s

Consolidated Net Tangible Assets, and any refinancing, extension or replacement thereof would cause the percentage of the Company’s

Consolidated Net Tangible Assets to be exceeded if calculated based on the Company’s Consolidated Net Tangible Assets on the date

of such refinancing, such percentage of the Company’s Consolidated Net Tangible Assets will not be deemed to be exceeded to the

extent the principal amount of such newly incurred Indebtedness, the liquidation preference of such newly issued Disqualified Equity or

Designated Preferred Stock does not exceed the sum of (i) the principal amount of such Indebtedness, the liquidation preference of

such Disqualified Equity or Designated Preferred Stock being refinanced, extended, or replaced plus (ii) any accrued and unpaid interest

on such Indebtedness, Disqualified Equity or Designated Preferred Stock, plus (iii) the amount of any tender premium or penalty or

premium required to be paid under the terms of the instrument or documents governing such refinanced Indebtedness, Disqualified Equity

or Designated Preferred Stock and any defeasance costs and any fees and expenses (including original issue discount, upfront fees or similar

fees) incurred in connection with the issuance of such new Indebtedness, Disqualified Equity or Designated Preferred Stock or the extension,

replacement, refunding, refinancing, renewal or defeasance thereof.

The amount of any Indebtedness outstanding as of

any date will be:

(1)           the

accreted value of the Indebtedness, in the case of any Indebtedness issued with original issue discount;

(2)           the

principal amount of the Indebtedness, in the case of any other Indebtedness; and

(3)           in

respect of Indebtedness of another Person secured by a Lien on the assets of the specified Person, the lesser of:

(A)            the

Fair Market Value of such assets at the date of determination; and

(B)            the

amount of the Indebtedness of the other Person.

For purposes of determining compliance with any

U.S. dollar-denominated restriction on the incurrence of Indebtedness, the U.S. dollar equivalent principal amount of Indebtedness denominated

in a foreign 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 a foreign 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

the principal amount of such Indebtedness being refinanced. The principal amount of any Indebtedness incurred to refinance other Indebtedness,

if incurred in a different currency from the Indebtedness being refinanced, shall be calculated based on the currency exchange rate applicable

to the currencies in which such respective Indebtedness is denominated that is in effect on the date of such refinancing.

Section 4.10          Asset

Sales.

The Company will not, and will not permit any of

its Restricted Subsidiaries to, consummate an Asset Sale unless:

(1) the Company (or the Restricted

Subsidiary, as the case may be) receives consideration (including by way of relief from, or by any Person assuming responsibilities for,

any liabilities, contingent or otherwise) at the time of the Asset Sale at least equal to the Fair Market Value of the assets or Equity

Interests issued or sold or otherwise disposed of (such Fair Market Value to be determined on the date of contractually agreeing to such

Asset Sale and which shall give effect to the assumption by another Person of any liabilities as provided for in clause (2)(A) below);

and

(2) at least 75% of the consideration

received in the Asset Sale by the Company or such Restricted Subsidiary, together with the consideration received in all other Asset Sales

by the Company or any Restricted Subsidiary since the Issue Date (on a cumulative basis) is in the form of cash or Cash Equivalents. For

purposes of the foregoing, each of the following shall be deemed to be cash:

(A)  any

liabilities, as shown on the Company’s most recent consolidated balance sheet, of the Company or any Restricted Subsidiary (other

than contingent liabilities and liabilities that are by their terms subordinated to the Notes or any Note Guarantees) that are assumed,

cancelled or otherwise forgiven by the transferee of any such assets pursuant to a written agreement that releases the Company or such

Restricted Subsidiary from further liability;

(B)   any

securities, notes or other Obligations received by the Company or any such Restricted Subsidiary from such transferee that are within

180 days after the Asset Sale (subject to ordinary settlement periods), converted by the Company or such Restricted Subsidiary into cash,

to the extent of the cash received in that conversion;

Investment, stock, property, assets or capital or other expenditure of the kind referred to in clause (2) or (3) of the next

succeeding paragraph;

(D)   any

Designated Non-cash Consideration received by the Company or any of its Restricted Subsidiaries in such Asset Sale having an aggregate

fair market value (as determined in good faith by the Company), taken together with all other Designated Non-cash Consideration received

pursuant to this clause (D), not to exceed the greater of (i) $150.0 million and (ii) 7.5% of the Company’s Consolidated

Net Tangible Assets at the time of receipt (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); and

(E)   accounts

receivable of a business retained by the Company or any of its Restricted Subsidiaries, as the case may be, following the sale of such

business, provided such accounts receivable (i) are not past due more than 60 days at the time of contractual agreement of

such Asset Sale and (ii) do not have a payment date greater than 90 days from the date of the invoices creating such accounts receivable.

Within 365 days after the receipt of any Net Proceeds

from an Asset Sale, the Company (or the applicable Restricted Subsidiary, as the case may be) may apply such Net Proceeds:

(1)  to

repay, repurchase or retire Senior Indebtedness of the Company or its Restricted Subsidiaries or any Indebtedness of a Restricted Subsidiary

that is not a Guarantor (or to make an offer to repurchase or give notice of redemption of such Indebtedness, provided that such

repurchase or redemption closes within 45 days after the end of such 365-day period);

(2)  to

acquire all or substantially all of the properties or assets of, or any Capital Stock of, another Person engaged primarily in a Permitted

Business, if, after giving effect to any such acquisition of Capital Stock, such Person is or becomes a Restricted Subsidiary of the Company;

(3)  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 Company or any Restricted Subsidiary owning an amount of the Capital Stock of such business such that

it constitutes or continues to constitute a Restricted Subsidiary; (b) a capital expenditure in a Permitted Business; or (c) acquisitions

by the Company or any Restricted Subsidiary of other assets, other than securities, in the case of clauses (a) and this clause (c),

either (i) that are or will be used or useful in the Permitted Business or (ii) that replace, in whole or in part, the properties

or assets that are the subject of such Asset Sale.

The requirement in clause (2) or (3) of the preceding paragraph

shall be deemed to be satisfied if a bona fide binding contract committing to make the investment, acquisition or expenditure referred

to therein is entered into by the Company or any of its Restricted Subsidiaries within the time period specified in the preceding paragraph

and such Net Proceeds are subsequently applied in accordance with such contract within 180 days following the date such agreement is entered

into. Pending the final application of any Net Proceeds, the Company or any Restricted Subsidiary may invest or utilize the Net Proceeds

in any manner that is not prohibited by this Indenture.

Any Net Proceeds from Asset Sales that are not

applied or invested as provided in the second preceding paragraph of this Section 4.10 will constitute “Excess Proceeds.”

When the aggregate amount of Excess Proceeds exceeds $50.0 million, within five Business Days thereof, the Company will make an Asset

Sale Offer to all Holders of Notes and all holders of other Indebtedness that is pari passu with the Notes containing provisions

similar to those set forth in this Indenture with respect to offers to purchase or redeem with the proceeds of sales of assets to purchase

the maximum principal amount of Notes and such other pari passu Indebtedness that may be purchased out of the Excess Proceeds.

The Company may satisfy the foregoing obligations with respect to any Net Proceeds from an Asset Sale by making an Asset Sale Offer with

respect to such Net Proceeds or equivalent amount prior to the time period that may be required by this Indenture with respect to all

or a part of the available Net Proceeds (the “Advance Portion”) in advance of being required to do so by this Indenture

(an “Advance Offer”). The offer price in any Asset Sale Offer will be equal to 100% of the principal amount plus accrued

and unpaid interest, if any, to the date of purchase, and will be payable in cash. If any Excess Proceeds (or in the case of an Advance

Offer, the Advance Portion) remain(s) after consummation of an Asset Sale Offer, the Company (or any Restricted Subsidiary) may use

those Excess Proceeds (or Advance Portion) for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount

of Notes and other pari passu Indebtedness tendered into such Asset Sale Offer exceeds the amount of Excess Proceeds (or in the

case of an Advance Offer, the Advance Portion), the Trustee shall (subject to the Depositary’s applicable procedures) select the

Notes and the representative of such other pari passu Indebtedness will (subject to the Depositary’s applicable procedures)

select such other pari passu Indebtedness to be purchased on a pro rata basis. Upon completion of each Asset Sale Offer

(or Advance Offer), the amount of Excess Proceeds (or the Advance Portion) will be reset at zero.

The Company will 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 and regulations

are applicable in connection with each repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities

laws or regulations conflict with the provisions of Section 3.10 hereof or this Section 4.10, the Company will comply with the

applicable securities laws and regulations and will not be deemed to have breached its obligations under Section 3.10 hereof or this

Section 4.10 by virtue of such compliance.

Section 4.11          Transactions

with Affiliates.

(a)   The

Company will not, and will not permit any of its Restricted Subsidiaries to, make any payment to, or sell, lease, transfer or otherwise

dispose of any of its properties or assets to, or purchase any property or assets from, or enter into or make or amend any transaction,

contract, agreement, understanding, loan, advance or Guarantee with, or for the benefit of, any Affiliate of the Company that would reasonably

be expected to exceed $25.0 million (measured, in the case of commercial agreements or recurring transactions, based on the value of payments

to or revenue received from such Affiliate reasonably expected by the Company during the term of such agreement) (each an “Affiliate

Transaction”), unless:

(1) the Affiliate Transaction is

on terms that are no less favorable to the Company or the relevant Restricted Subsidiary than those that could have been obtained in a

comparable transaction by the Company or such Restricted Subsidiary with an unrelated Person or, if in the good faith judgment of the

Company, no comparable transaction is available with which to compare such Affiliate Transaction, such Affiliate Transaction is fair to

the Company or the relevant Restricted Subsidiary from a financial or commercial point of view; and

(2) the Company delivers to the

Trustee with respect to any Affiliate Transaction (or series of related Affiliate Transactions) involving aggregate consideration in excess

of $100.0 million (measured, in the case of commercial agreements or recurring transactions, based on the value of payments to or revenue

received from such Affiliate reasonably expected by the Company during the term of such agreement), a resolution of the Board of Directors

of the Company set forth in an Officer’s Certificate certifying that such Affiliate Transaction complies with clause (1) of

this Section 4.11(a) and that such Affiliate Transaction has been approved by (i) a majority of the disinterested members

of the Board of Directors of the Company, if any, (ii) the conflicts committee of the Board of Directors or (iii) the audit

committee of the Board of Directors.

(b)   The

following items will not be deemed to be Affiliate Transactions and, therefore, will not be subject to the provisions of Section 4.11(a) hereof:

(1) reasonable fees and compensation

paid to or for the benefit of any employee, officer or director of the Company, any of its Restricted Subsidiaries or any direct or indirect

parent (including the Parent), and any stock option plan, severance arrangement, employment agreement, employee benefit plan, officer

or director indemnification agreement or any similar arrangement entered into by the Company or any of its Restricted Subsidiaries or

any direct or indirect parent (including the Parent) existing on the Issue Date, or entered into thereafter in the ordinary course of

business, and any indemnities or other transactions permitted or required by bylaw, statutory provisions or any of the foregoing agreements,

plans or arrangements;

(2) transactions between or among

the Company and/or its Restricted Subsidiaries or any Parent Company;

(3) transactions with a Person (other

than an Unrestricted Subsidiary of the Company) that is an Affiliate of the Company or Parent solely because the Company or Parent owns,

directly or through a Restricted Subsidiary, an Equity Interest in, or controls, such Person;

(4) any issuance or sale of Equity

Interests (other than Disqualified Equity or Designated Preferred Stock) of the Company (or the Parent) to Affiliates or any Qualified

Owner of the Company or to any former, current or future director, manager, officer, employee or consultant of the Company, any of its

Subsidiaries or any direct or indirect parent thereof;

(5) Permitted Investments or Restricted

Payments that do not violate Section 4.07 hereof;

(6) customary compensation, indemnification

and other benefits made available to officers, directors or employees of the Company, a Restricted Subsidiary of the Company or any Parent

Company, including reimbursement or advancement of out-of-pocket expenses and provisions of officers’ and directors’ liability

insurance;

(7) in the case of gathering, handling,

transporting, recycling, waste water treatment, sale of recycled, brackish and produced water, gas transportation services, sale of skim

oil, solid waste management, reclamation services or other operational contracts consistent with or included in the scope of a Permitted

Business, any such contracts are entered into in the ordinary course of business on terms substantially similar to those contained in

similar contracts entered into by the Company or any Restricted Subsidiary and third parties, or are otherwise fair to the Company or

any Restricted Subsidiary from a financial or commercial point of view, as determined in good faith by the Company or an officer thereof;

(8) the existence of, or the performance

by the Company or any Restricted Subsidiary of its obligations under the terms of, any agreements to which it is a party as of the date

of the Offering Memorandum and any amendments thereto and any similar agreements which it may enter into thereafter; provided,

however, that the existence of, or the performance by the Company or any Restricted Subsidiary of its obligations under, any future

amendment to such agreements or under any such similar agreements shall only be permitted by this clause (8) to the extent that the

terms of any such amendment or new agreement, taken as a whole, are not less favorable to the Holders in any material respect;

(9) if such Affiliate Transaction

is with a Person in its capacity as a holder of Indebtedness or Equity Interests of the Company or any of its Restricted Subsidiaries,

a transaction in which such Person is treated no more favorably than the other holders of such Indebtedness or Equity Interests;

(10) (A) Guarantees by the

Company or any of its Restricted Subsidiaries of the performance of obligations of Unrestricted Subsidiaries or Joint Ventures in the

ordinary course of business, except for Guarantees of Indebtedness in respect of borrowed money, and (B) pledges by the Company or

any Restricted Subsidiary of Capital Stock in Unrestricted Subsidiaries or Joint Ventures for the benefit of lenders or other creditors

of Unrestricted Subsidiaries or Joint Ventures as contemplated by clause (13) of the definition of “Permitted Liens” so long

as any such transaction described in this clause (B), if involving aggregate consideration in excess of $50.0 million, has been approved

by (i) a majority of the disinterested members of the Board of Directors of the Company, if any, (ii) the conflicts committee

of the Board of Directors or (iii) the audit committee of the Board of Directors;

(11) any transaction in which the Company

or any of its Restricted Subsidiaries, as the case may be, delivers to the Trustee a letter from an accounting, appraisal or investment

banking firm of national standing stating that such transaction is fair to the Company or such Restricted Subsidiary from a financial

point of view or that such transaction meets the requirements of Section 4.11(a)(1) hereof;

(12) (a) payments by the Company

and its Subsidiaries pursuant to, and the entry into, tax sharing agreements among the Company and its Subsidiaries and any Parent Company;

provided that in each case the amount of such payments by the Company and its Subsidiaries are permitted under clauses (13) or (14) of

Section 4.07(b) and (b) the formation and maintenance of any consolidated, combined, unitary or similar group or subgroup

for tax, accounting or cash pooling or management purposes in the ordinary course of business;

(13) any transactions between the Company

or any Restricted Subsidiary and any Person, a director of which is also a director of the Company, a Restricted Subsidiary or a Parent

Company, provided that such director abstains from voting as a director of the Company, or the Restricted Subsidiary or Parent

Company, as applicable, in connection with the approval of the transaction;

(14) customary payments by the Company

and any of its Restricted Subsidiaries to any Qualified Owner made for any financial advisory, financing, underwriting or placement services

or in respect of other investment banking activities (including in connection with acquisitions or divestitures), which payments are approved

by the majority of the members of the Board of Directors of the Company, in good faith;

(15) Permitted Intercompany Activities

and related transactions; and

(16) a Joint Venture which would constitute

a transaction with an Affiliate solely as a result of the Company or any Restricted Subsidiary owning an Equity Interest or otherwise

controlling such Joint Venture or similar entity.

Section 4.12          Liens.

The Company will not, and will not permit any Restricted

Subsidiaries to, create, incur, assume or otherwise cause to exist or become effective any Lien (an “Initial Lien”)

of any kind (other than Permitted Liens) securing Indebtedness, upon any of their property or assets, now owned or hereafter acquired,

unless the Notes or any Note Guarantee of such Restricted Subsidiary, as applicable, are secured on an equal and ratable basis with the

Indebtedness so secured until such time as such Indebtedness is no longer secured by a Lien.

Any Lien created for the benefit of Holders of

the Notes pursuant to the preceding paragraph shall provide by its terms that such Lien shall be automatically and unconditionally released

and discharged upon the release and discharge of the Initial Lien.

Section 4.13          Offer

to Repurchase Upon Change of Control.

(a)   Upon

the occurrence of a Change of Control, the Company will make an offer (a “Change of Control Offer”) to each Holder

of Notes to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of that Holder’s Notes

at a purchase price in cash equal to 101% of the aggregate principal amount of Notes repurchased, plus accrued and unpaid interest, if

any, on the Notes repurchased to, but excluding, the date of purchase (the “Change of Control Payment”), subject to

the rights of Holders of Notes on the relevant record date to receive interest due on an interest payment date that is on or prior to

the date of purchase. Within 30 days following any Change of Control, the Company will send a notice to each Holder, with a copy to the

Trustee, describing the transaction or transactions that constitute the Change of Control and stating:

(1) that the Change of Control Offer

is being made pursuant to this Section 4.13 and that all Notes tendered will be accepted for payment;

(2) the purchase price and the purchase

date, which shall be no earlier than 30 days and no later than 60 days from the date such notice is sent (the “Change of Control

Payment Date”);

(3) that any Note not tendered will

continue to accrue interest;

(4) that, unless the Company defaults

in the payment of the Change of Control Payment, all Notes accepted for payment pursuant to the Change of Control Offer will cease to

accrue interest after the Change of Control Payment Date;

(5) that Holders electing to have

any Notes purchased pursuant to a Change of Control Offer will be required to surrender the Notes, with the form entitled “Option

of Holder to Elect Purchase” attached to the Notes completed, or transfer by book-entry transfer, to the Paying Agent at the address

specified in the notice prior to the close of business on the third Business Day preceding the Change of Control Payment Date;

(6) that Holders will be entitled

to withdraw their election if the Paying Agent or depositary receives, not later than the close of business on the second Business Day

preceding the Change of Control Payment Date, a telegram, telex, electronic image scan, facsimile transmission or letter setting forth

the name of the Holder, the principal amount of Notes delivered for purchase, and a statement that such Holder is withdrawing his election

to have the Notes purchased; and

(7) that Holders whose Notes are

being purchased only in part will be issued new Notes equal in principal amount to the unpurchased portion of the Notes surrendered, which

unpurchased portion must be equal to $2,000 in principal amount or an integral multiple of $1,000 in excess thereof.

The Company will comply with the requirements of

Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations

are applicable in connection with the repurchase of the Notes as a result of a Change of Control. To the extent that the provisions of

any securities laws or regulations conflict with the provisions of this Section 4.13, the Company will comply with the applicable

securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.13 by virtue of such

compliance.

(b)   On

the Change of Control Payment Date, the Company will, to the extent lawful:

(1) accept for payment all Notes

or portions of Notes properly tendered pursuant to the Change of Control Offer;

(2) deposit with the Paying Agent

or depositary an amount equal to the Change of Control Payment in respect of all Notes or portions of Notes properly tendered; and

(3) deliver or cause to be delivered

to the Trustee the Notes properly accepted together with an Officer’s Certificate stating the aggregate principal amount of Notes

or portions of Notes being purchased by the Company.

The Paying Agent or depositary will promptly mail

to each Holder of Notes properly tendered the Change of Control Payment for such Notes (or, if all the Notes are then in global form,

it will make such payment through the facilities of DTC), and the Trustee will promptly authenticate and mail (or cause to be transferred

by book entry) to each Holder a new Note equal in principal amount to any unpurchased portion of the Notes surrendered, if any; provided,

that each new Note will be in a principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. The Company will publicly

announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

The provisions described above that require the

Company to make a Change of Control Offer following a Change of Control will be applicable whether or not any other provisions of this

Indenture are applicable.

anything to the contrary in this Section 4.13, the Company will not be required to make a Change of Control Offer upon a Change of

Control if (1) a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements

set forth in this Section 4.13 and purchases all Notes properly tendered and not withdrawn under the Change of Control Offer, (2) notice

of redemption has been given pursuant to Section 3.03 hereof, unless and until there is a default in payment of the applicable redemption

price, or (3) in connection with or in contemplation of any Change of Control, the Company or a third party makes an offer to purchase

(an “Alternate Offer”) any and all Notes validly tendered and not withdrawn at a cash price equal to or higher than

the Change of Control Payment and purchases all Notes properly tendered and not withdrawn under the Alternate Offer.

Section 4.14          Additional

Guarantees.

If, after the Issue Date, any Restricted Subsidiary

of the Company that is not already a Guarantor guarantees any Indebtedness of the Company or a Guarantor under a Credit Facility in an

aggregate principal amount in excess of $50.0 million for any such Restricted Subsidiary, then that Subsidiary will become a Guarantor

by executing and delivering to the Trustee a supplemental indenture substantially in the form of Exhibit E hereto within 30 calendar

days of the date on which it guaranteed such Indebtedness; provided that the preceding shall not apply to Subsidiaries of the Company

that have been properly designated as Unrestricted Subsidiaries in accordance with this Indenture for so long as they continue to constitute

Unrestricted Subsidiaries. Notwithstanding the preceding, any Note Guarantee of a Restricted Subsidiary that was incurred pursuant to

this Section 4.14 will be released in accordance with Section 10.05 hereof.

Section 4.15          Designation

of Restricted and Unrestricted Subsidiaries.

As of the Issue Date, each of Wildfire Water Solutions, Inc.

and Select Water Reuse, LLC and their respective Subsidiaries will be Unrestricted Subsidiaries. The Company may from time to time designate

any other Restricted Subsidiary to be an Unrestricted Subsidiary if that designation would not cause a Default. If a Restricted Subsidiary

is designated as an Unrestricted Subsidiary, the aggregate Fair Market Value of all outstanding Investments owned by the Company and its

Restricted Subsidiaries in the Subsidiary designated as an Unrestricted Subsidiary will be deemed to be an Investment made as of the time

of the designation and will either reduce the amount available for Restricted Payments under Section 4.07 hereof or qualify as a

Permitted Investment under one or more clauses of the definition of Permitted Investments, as determined by the Company; provided that

any designation will only be permitted if the Investment would be permitted at that time and if the Restricted Subsidiary otherwise meets

the definition of an Unrestricted Subsidiary.

Any designation of a Subsidiary of the Company

as an Unrestricted Subsidiary will be evidenced to the Trustee by filing with the Trustee an Officer’s Certificate certifying that

such designation complied with the preceding conditions and was permitted by Section 4.07 hereof.

The Company may at any time designate any Unrestricted

Subsidiary to be a Restricted Subsidiary of the Company; provided that such designation will be deemed to be an incurrence of Indebtedness

by a Restricted Subsidiary of the Company of any outstanding Indebtedness of such Unrestricted Subsidiary, and such designation will only

be permitted if (1) such Indebtedness is permitted under Section 4.09 hereof, calculated on a pro forma basis as if such designation

had occurred at the beginning of the Reference Period and (2) no Default or Event of Default would be in existence following such

designation.

Section 4.16          Termination

of Covenants.

(a)   If

on any date following the Issue Date: (i) the Notes are rated an Investment Grade Rating by (a) at least one Rating Agency to

the extent the Notes are rated by two or fewer Rating Agencies and (b) at least two Rating Agencies to the extent the Notes are rated

by three or more Rating Agencies, and (ii) no Default or Event of Default shall have occurred and be continuing then, upon the Company’s

delivery of an Officer’s Certificate notifying the Trustee that the Notes are rated an Investment Grade Rating as of the date of

such Officer’s Certificate (the “Termination Date”), the Company and its Restricted Subsidiaries will no longer

be subject to the following provisions of this Indenture: (1) Section 4.07; (2) Section 4.08; (3) Section 4.09;

(4) Section 4.10; (5) Section 4.11; (6) Section 4.14; (7) Section 4.15; and (8) clause (4) of

Section 5.01(a). For the avoidance of doubt, such provisions of this Indenture will not be reinstated following the Termination Date.

(b)   However,

the Company and its Restricted Subsidiaries will remain subject to the other provisions of this Indenture, including: (1) Section 4.03;

(2) Section 4.12 (with associated incurrence capacity as if the covenant described in Section 4.09 remained in effect);

and (3) Section 5.01 (with the exception of clause (4) of Section 5.01(a)).

Company may not designate any of its Subsidiaries as Unrestricted Subsidiaries after the Termination Date.

(d)   The

Trustee will have no obligation to independently determine or verify if a Termination Date has occurred or to notify the Holders of the

same. The Trustee may conclusively rely on all Officer’s Certificates delivered pursuant to this Section 4.16 without any duty

of further inquiry.

the successor Person and not to the Company), and may exercise every right and power of the Company under this Indenture with the same

effect as if such successor Person had been named as the Company herein.

ARTICLE 6

(6) default under any instrument

under which any Indebtedness for money borrowed has been incurred by the Company or any of its Restricted Subsidiaries (or the payment

of which is Guaranteed by the Company or any of its Restricted Subsidiaries), whether such Indebtedness or Guarantee now exists, or is

created after the Issue Date, if that default:

(A)   is

caused by a failure to pay principal of such Indebtedness prior to the expiration of the grace period provided in such Indebtedness on

the date of such default (a “Debt Payment Default”); or

(B)   results

in the acceleration of such Indebtedness prior to its express maturity,

and, in each case, the principal amount of any such Indebtedness,

together with the principal amount of any other such Indebtedness under which there has been a Debt Payment Default or the maturity of

which has been so accelerated, aggregates $75.0 million or more, and, within 20 Business Days of such Debt Payment Default or acceleration,

(ii) any such acceleration is rescinded, or (iii) such Indebtedness is repaid, in each case, during the 30-day period commencing

upon the end of any applicable grace period for such Debt Payment Default or the occurrence of such acceleration, as applicable, any Event

(7) failure by the Company or any

of the Company’s Restricted Subsidiaries to pay final judgments entered by a court or courts of competent jurisdiction aggregating

in excess of $75.0 million, which judgments are not paid, discharged or stayed for a period of 60 days;

of the Company that, taken together, would constitute a Significant Subsidiary; or

the liquidation of the Company or any of the Company’s Restricted Subsidiaries that is a Significant Subsidiary or any group of

Restricted Subsidiaries of the Company that, taken together, would constitute a Significant Subsidiary;

and the order or decree remains unstayed and in effect for

60 consecutive days; and

(10) except as permitted by this

Indenture, any Note Guarantee is held in any judicial proceeding to be unenforceable or invalid or ceases for any reason to be in full

force and effect, or any Guarantor, or any Person acting on behalf of any Guarantor, denies or disaffirms its Obligations under its Note

Guarantee.

Section 6.02          Acceleration.

(a)   In

the case of an Event of Default specified in clause (8) or (9) of Section 6.01 hereof, with respect to the Company or any

Restricted Subsidiary of the Company that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Company that, taken

together, would constitute a Significant Subsidiary, the principal of, and accrued and unpaid interest, if any, on, all outstanding Notes

will become due and payable immediately without further action or notice. If any other Event of Default occurs and is continuing, the

Trustee or the Holders of at least 25% in aggregate principal amount of the then outstanding Notes may declare all the principal of, and

accrued and unpaid interest, if any, on, Notes to be due and payable immediately; provided that a notice of Default may not be given with

respect to any action taken, and reported publicly or to Holders of Notes, more than two years prior to such notice of Default.

(b)   Upon

any such declaration, the unpaid principal of, and accrued and unpaid interest, if any, on, Notes shall become due and payable immediately.

Holders of a majority in aggregate principal amount of the then outstanding Notes by notice to the Trustee may, on behalf of the Holders

of all of the Notes, rescind an acceleration or waive any existing Default or Event of Default and its consequences under this Indenture

except a continuing Default or Event of Default in the payment of interest, or premium, if any, on, or the principal of, the Notes.

(d)   Any

notice of Default, notice of acceleration or instruction delivered 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 of Notes (each a “Directing

Holder”) must be accompanied by a written representation from each such Holder delivered to the Company and the Trustee that

such Holder is not (or, in the case such Holder is DTC or its nominee, that such Holder is being instructed solely by beneficial owners

that are not) Net Short (a “Position Representation”), which representation, in the case of a Noteholder Direction

relating to the delivery of a notice of Default 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 Company (with a copy to the Trustee) with such other information as the Company may reasonably request

from time to time in order to verify the accuracy of such Directing Holder’s Position Representation within five Business Days of

request therefor (a “Verification Covenant”). The Trustee shall have no duty whatsoever to provide this information

to the Company or to obtain this information for the Company. In any case in which the Holder is DTC or its nominee, any Position Representation

or Verification Covenant required hereunder shall be provided by the beneficial owner of the Notes in lieu of DTC or its nominee and DTC

shall be entitled to conclusively rely on such Position Representation and Verification Covenant in delivering its direction to the Trustee.

If the Holder of the applicable Notes is a clearing system or a common safekeeper or its nominee, any Position Representation required

hereunder shall be provided by the clearing system or the common safekeeper or its nominee or by the beneficial owner of an interest in

such Global Notes after delivery to the Trustee of appropriate confirmation of beneficial ownership satisfactory to the Trustee.

(e)   Notwithstanding

anything to the contrary in this Section 6.02, any Noteholder Direction delivered to the Trustee during the pendency of an Event

of Default as the result of bankruptcy or similar proceedings shall not require compliance with this Section 6.02. In addition, for

the avoidance of doubt, this Section 6.02 shall not apply to any Holder that is a Regulated Bank.

(f)   If,

following the delivery of a Noteholder Direction, but prior to acceleration of the Notes, the Company 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 Company 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

Default, Event of Default or acceleration (or notice thereof) that resulted from the applicable Noteholder Direction, the cure period

with respect to such Default shall be automatically stayed and the cure period with respect to such Default or Event of Default shall

be automatically reinstituted and any remedy stayed pending a final and non-appealable determination of a court of competent jurisdiction

on such matter. If, following the delivery of a Noteholder Direction, but prior to acceleration of the Notes, the Company 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 Default or Event of Default that resulted

from the applicable Noteholder Direction shall be automatically reinstituted and any remedy stayed pending satisfaction of such Verification

Covenant.

(g)   Any

breach of the Position Representation as confirmed by a final and non-appealable determination of a court of competent jurisdiction on

such matter shall result in such Holder’s participation in such Noteholder Direction being disregarded; and, if, without the participation

of such Holder, the percentage of Notes held by the remaining Holders of the Notes 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 shall be voided and the Trustee shall be deemed not to have

received such Noteholder Direction or any notice of such Default or Event of Default; provided, however, this shall not invalidate

any indemnity and/or security provided by the Directing Holders to the Trustee which obligations shall continue to survive. If the Directing

Holder has satisfied its Verification Covenant, then the Trustee shall be permitted to act in accordance with such Noteholder Direction.

Notwithstanding the above, if such Directing Holder’s participation is not required to achieve the requisite level of consent of

Holders required under this Indenture to give such Noteholder Direction, the Trustee shall be permitted to act in accordance with such

Noteholder Direction notwithstanding any action taken or to be taken by the Company (as described above).

(h)   Notwithstanding

anything in Sections 6.02(f) and (g) to the contrary, any Noteholder Direction delivered to the Trustee during the pendency

of an Event of Default specified in clauses (1), (2), (8) or (9) of Section 6.01 hereof shall not require compliance

with the foregoing paragraphs.

(i)   For

the avoidance of doubt, the Trustee shall be entitled to conclusively rely on any Noteholder Direction delivered to it in accordance with

this Indenture, shall have no duty to inquire as to or investigate the accuracy or authenticity of any Position Representation or determine

whether it complies with the provisions of this Indenture, enforce compliance with any Verification Covenant, to monitor, investigate,

verify or otherwise determine if a Holder has a Net Short position, inquire if the Company will seek action to determine if a Directing

Holder has breached its Position Representation or monitor any court proceedings undertaken in connection therewith, 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 and shall have no liability for ceasing

to take any action or staying any remedy, or otherwise failing to act in accordance with a Noteholder Direction. With their acquisition

of the Notes, each Holder by its purchase of the Notes and subsequent purchaser of the Notes consents to the delivery of its Position

Representation by the Trustee to the Company in accordance with the terms of this Section 6.02. The Trustee shall have no liability

to the Company, any Holder or any Person in acting in good faith on a Noteholder Direction or for determining whether any Holder has delivered

a Position Representation.

(j)   Each

Holder by its purchase of the Notes and subsequent purchaser of the Notes waives any and all claims, in law and/or in equity, against

the Trustee and agrees not to commence any legal proceeding against the Trustee in respect of, and agrees that the Trustee will not be

liable for any action that the Trustee takes in accordance with Section 6.02(d) through Section 6.02(i), or arising out

of or in connection with following instructions or taking actions in accordance with a Noteholder Direction. Each Holder by its purchase

of the Notes and subsequent purchaser of the Notes acknowledges and agrees that neither the Trustee nor any agent thereof shall be liable

to any person for acting or refraining to act in accordance with (i) Section 6.02(d) through Section 6.02(i), (ii) any

Noteholder Direction, (iii) any Officer’s Certificate delivered in connection therewith, or (iv) its duties under this

Indenture as Trustee as determined by the Trustee as a result of Section 6.02(d) through Section 6.02(i). The Company agrees

to waive any and all claims, in law and/or in equity, against the Trustee, and not to commence any legal proceeding against the Trustee

in respect of, and agrees that the Trustee will not be liable for any action that the Trustee takes in accordance with Section 6.02(d) through

Section 6.02(i), or arising out of or in connection with following instructions or taking actions in accordance with a Noteholder

Direction. In connection with the requisite percentages required under this Section 6.02, the Trustee shall also treat all outstanding

Notes equally irrespective of any Position Representation in determining whether the requisite percentage has been obtained with respect

to the initial delivery of the Noteholder Direction. The Company confirms that any and all other actions that the Trustee takes or omits

to take under this Section 6.02 and all fees, costs and expenses of the Trustee and its agents and counsel arising hereunder and

in connection herewith shall be covered by Section 7.06.

Section 6.03          Other

Remedies.

If an Event of Default occurs and is continuing,

the Trustee may pursue any available remedy to collect the payment of principal, premium and interest, if any, on the Notes or to enforce

the performance of any provision of the Notes or this Indenture.

The Trustee may maintain a proceeding even if it

does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder

of a Note in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver

of or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law.

Section 6.04          Waiver

of Past Defaults.

Holders of a majority in aggregate principal amount

of the then outstanding Notes by notice to the Trustee may on behalf of the Holders of all of the Notes waive an existing Default or Event

of Default and its consequences hereunder, except a continuing Default or Event of Default in the payment of the principal of, premium

or interest on the Notes (including in connection with an offer to purchase); provided, however, that the Holders of a majority

in aggregate principal amount of the then outstanding Notes may rescind an acceleration and its consequences, including any related payment

default that resulted from such acceleration. Upon any such waiver, and the payment of all amounts due the Trustee in connection with

such Default, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every

purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon.

Section 6.05          Control

by Majority.

Holders of a majority in aggregate principal amount

of the then outstanding Notes may direct the time, method and place of conducting any proceeding for exercising any remedy available to

the Trustee or exercising any trust or power conferred on it. However, the Trustee may refuse to follow any direction that conflicts with

law or this Indenture or that the Trustee determines may be unduly prejudicial to the rights of other Holders of Notes or that may involve

the Trustee in personal liability (provided, however, that the Trustee shall be under no obligation to determine whether

any action or inaction is unduly prejudicial to any Holder) and the Trustee has not been offered indemnity and/or security satisfactory

to it against any loss, fee, cost, claim, damage, liability or expense (including reasonable attorney’s fees and expenses).

Section 6.06          Limitation

on Suits.

A Holder may pursue a remedy with respect to this

Indenture or the Notes only if:

(1) such Holder gives to the Trustee

written notice that an Event of Default is continuing;

(2) Holders of at least 25% in aggregate

principal amount of the then outstanding Notes make a written request to the Trustee to pursue the remedy;

(3) such Holder or Holders offer

and, if requested, provide to the Trustee indemnity and/or security satisfactory to the Trustee against any loss, fee, cost, claim, damage,

liability or expense (including reasonable attorney’s fees and expenses);

(4) the Trustee does not comply

with the request within 60 days after receipt of the request and the offer of indemnity and/or security; and

(5) during such 60-day period, Holders

of a majority in aggregate principal amount of the then outstanding Notes do not give the Trustee a direction inconsistent with such request.

A Holder of a Note may not use this Indenture to

prejudice the rights of another Holder of a Note or to obtain a preference or priority over another Holder of a Note. The Trustee will

have no duty to determine whether any Holder’s use of this Indenture complies with the preceding sentence.

Section 6.07          Rights

of Holders of Notes to Receive Payment.

Notwithstanding any other provision of this Indenture,

the right of any Holder of a Note to receive payment of principal, premium and interest on the Note, on or after the respective due dates

expressed in the Note, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be amended

in a manner adverse to such Holder without the consent of such Holder.

Section 6.08          Collection

Suit by Trustee.

If an Event of Default specified in Section 6.01(1) or

(2) hereof occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust

against the Company for the whole amount of principal of, premium and interest remaining unpaid on, the Notes and interest on overdue

principal and, to the extent lawful, interest and 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.

Section 6.09          Trustee

May File Proofs of Claim.

The Trustee is authorized to file such proofs of

claim and 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 the Holders of the Notes

allowed in any judicial proceedings relative to the Company (or any other obligor upon the Notes), their creditors or their property and

shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims

and any custodian 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 to the Trustee any amount due to 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 7.06 hereof. To the extent that the payment of any such compensation, expenses, disbursements and advances

of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.06 hereof out of the estate in any

such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and

all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding whether

in liquidation or under any plan of reorganization or arrangement or otherwise. 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, or to authorize the Trustee to vote in respect of the claim of any Holder

in any such proceeding.

Section 6.10          Priorities.

If the Trustee collects any money pursuant to this

Article 6, it shall pay out the money in the following order:

First:      to

the Trustee, the Agents and the Custodian, and their respective agents and attorneys for any and all amounts due under this Indenture,

Trustee and the costs, fees, and expenses of collection;

Second: to

Holders of Notes for amounts due and unpaid on the Notes for principal, premium and interest ratably, without preference or priority of

any kind, according to the amounts due and payable on the Notes for principal, premium, if any, and interest, respectively; and

Third:    to

the Company or to such party as a court of competent jurisdiction shall direct.

The Trustee may fix a record date and payment date

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 attorneys’ fees, against any party litigant in the suit, having due regard to

the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the

Trustee, a suit by a Holder of a Note pursuant to Section 6.07 hereof, or a suit by Holders of more than 10% in aggregate principal

amount of the then outstanding Notes.

Section 7.01          Duties

of Trustee.

(a)   If

an Event of Default has occurred and is continuing, the Trustee will exercise such of the rights and powers vested in it by this Indenture,

and use the same degree of care and skill in its exercise, as a prudent person would exercise or use under the circumstances in the conduct

of such person’s own affairs.

(b)   Except

during the continuance of an Event of Default:

(1) the duties of the Trustee will

be determined solely by the express provisions of this Indenture and the Trustee need perform only those duties that are specifically

set forth in this Indenture and no others, and no implied covenants or obligations shall be read into this Indenture against the Trustee;

and

(2) in the absence of willful misconduct

on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein,

upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, the Trustee will

examine the certificates and opinions to determine whether or not they conform on their face to the requirements of this Indenture.

Trustee may not be relieved from liabilities for its own grossly negligent action, its own grossly negligent failure to act, or its own

willful misconduct, except that:

(1) this paragraph does not limit

the effect of paragraph (b) of this Section 7.01;

(2) the Trustee will not be liable

for any error of judgment made in good faith by a Responsible Officer, unless it is proved that the Trustee was grossly negligent in

ascertaining the pertinent facts; and

(3) the Trustee will not be liable

with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 6.05

hereof.

(d)            Whether

or not therein expressly so provided, every provision of this Indenture that in any way relates to the Trustee is subject to paragraphs

(a), (b), and (c) of this Section 7.01.

(e)            No

provision of this Indenture will require the Trustee to expend or risk its own funds or incur any liability. The Trustee will be under

no obligation to exercise any of its rights and powers under this Indenture at the request of any Holders, unless such Holder has furnished

to the Trustee indemnity and/or security satisfactory to the Trustee against any loss, fee, cost, claim, damage, liability or expense

(including reasonable attorney’s fees and expenses).

(f)            The

Trustee will not be liable for interest on or the investment of any money received by it except as the Trustee may agree in writing with

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

shall have no investment discretion and the Trustee’s only responsibility for investments shall be to follow the written instructions

of the Company. Absent written investment instructions, all moneys or deposits held by the Trustee shall be uninvested. The Trustee shall

not incur any liability for losses arising from any investments made pursuant to this Indenture. The Trustee shall not be required to

determine the suitability or legality of any investments.

Section 7.02         Rights

of Trustee.

Trustee may conclusively rely and shall be fully protected in acting or refraining from acting upon any document (whether in original

or facsimile form or PDF transmission or executed or signed in accordance with Section 12.11 hereof) believed by it to be genuine

and to have been signed or presented by the proper Person. The Trustee need not investigate any fact or matter stated in the document.

(b)            Before

the Trustee acts or refrains from acting, it may require an Officer’s Certificate and an Opinion of Counsel. The Trustee will not

be liable for any action it takes or omits to take in good faith in reliance on such Officer’s Certificate or Opinion of Counsel.

Prior to taking, suffering or admitting any action, the Trustee may consult with counsel of the Trustee’s own choosing and the

advice of such counsel or any Opinion of Counsel will be full and complete authorization and protection from liability in respect of

any action taken, suffered or omitted by it hereunder in good faith and in conclusive reliance thereon.

Trustee may act through its attorneys and agents and will not be responsible for the misconduct or negligence of any attorney or agent

appointed with due care.

(d)            The

Trustee will not be liable for any action it takes or omits to take in good faith that it believes to be authorized or within the rights

or powers conferred upon it by this Indenture.

(e)            Unless

otherwise specifically provided in this Indenture, any demand, request, direction or notice from the Company will be sufficient if signed

by an Officer of the Company.

(f)            The

Trustee will be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction

of any of the Holders unless such Holders have furnished to the Trustee indemnity and/or security satisfactory to the Trustee against

the losses, fee, cost, claim, damage, liabilities and expenses (including reasonable attorney’s fees and expenses) that might be

incurred by it in compliance with such request or direction.

(g)            The

Trustee shall not be deemed to have notice of a Default or an Event of Default unless a Responsible Officer of the Trustee (i) receives

written notice of such Default or Event of Default, and such notice references this Indenture and the Notes or (ii) otherwise has

actual knowledge of such Default or Event of Default in connection with Sections 6.01(1) or 6.01(2).

(h)            In

no event shall the Trustee be responsible or liable for special, indirect, punitive or consequential loss or damage of any kind whatsoever

(including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or

damage and regardless of the form of action.

(i)            The

rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified,

are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder.

(j)            Any

discretion, permissive right or privilege in favor of the Trustee shall not be construed as a duty or obligation.

(k)            The

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

(l)            The

Trustee will not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument,

opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or

documents, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see

fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine during normal

business hours the books, records and premises of the Company, personally or by agent or attorney at the sole cost of the Company, and

shall incur no liability or additional liability of any kind by reason of such inquiry or investigation.

(m)            The

Trustee may request that the Company and each of the Guarantors shall deliver to the Trustee an Officer’s Certificate setting forth

the names of individuals and/or titles of Officers of the Company and each Guarantor, as applicable, authorized at such time to take

specified actions pursuant to this Indenture of the Company, the Notes and the Guarantees, which Officer’s Certificate may be signed

by any Person authorized to sign an Officer’s Certificate, including any Person specified as so authorized in any such certificate

previously delivered and not superseded.

(n)            The

Company will be responsible for making calculations called for under the Notes, including but not limited to determination of redemption

price, premium, if any, and any other amounts payable on the Notes. The Company will make the calculations in good faith and, absent

manifest error, its calculations will be final and binding on the Holders of the Notes. The Company will provide a schedule of its calculations

to the Trustee when applicable, and the Trustee is entitled to rely conclusively on the accuracy of the Company’s calculations

without independent verification.

(o)            The

Trustee shall not be liable for any action taken or omitted by it in good faith at the direction of the Holders of not less than a majority

in aggregate principal amount of the Notes as to the time, method and place of conducting any proceedings for any remedy available to

the Trustee or the exercising of any power conferred by this Indenture.

Section 7.03         Individual

Rights of Trustee.

The Trustee in its individual or any other capacity

may become the owner or pledgee of Notes and may otherwise deal with the Company or any Affiliate of the Company with the same rights

it would have if it were not Trustee. The Trustee is also subject to Sections 7.08 and 7.09 hereof.

Section 7.04         Trustee’s

Disclaimer.

The Trustee will not be responsible for and makes

no representation as to the validity, adequacy or enforceability of this Indenture or the Notes, it shall not be liable for the acts

or omissions of the Company or accountable for the Company’s use of the proceeds from the Notes or any money paid to the Company

or upon the Company’s direction under any provision of this Indenture, it will not be responsible for the use or application of

any money received by any Paying Agent other than the Trustee, and it will not be responsible for any statement or recital herein or

any statement in the Notes or any other document in connection with the sale of the Notes or pursuant to this Indenture other than its

certificate of authentication. The Trustee shall not be liable in its individual capacity for the Obligations evidenced by the Notes

or this Indenture.

Section 7.05         Notice

of Defaults.

If a Default or Event of Default occurs and is

continuing and if it is actually known to a Responsible Officer of the Trustee in accordance with Section 7.02(g), the Trustee will

send to Holders of Notes a notice of the Default or Event of Default within 90 days after it occurs. Except in the case of a Default

or Event of Default in payment of principal of, premium, if any, or interest on any Note, the Trustee may withhold the notice if and

so long as it in good faith determines that withholding the notice is in the interests of the Holders of the Notes.

Section 7.06         Compensation

and Indemnity.

(a)            The

Company will pay to the Trustee from time-to-time compensation as agreed to in writing by the Trustee and the Company for its acceptance

of this Indenture and services hereunder. The Trustee’s compensation will not be limited by any law on compensation of a trustee

of an express trust. The Company will reimburse the Trustee promptly upon request for all reasonable disbursements, advances and expenses

incurred or made by it in addition to the compensation for its services. Such expenses will include the reasonable compensation, disbursements

and expenses of the Trustee’s agents and counsel.

(b)            The

Company and the Guarantors will indemnify, defend and protect, jointly and severally, the Trustee (in its individual capacity and in

any capacity under this Indenture and any other document or transaction entered into in connection herewith) and its agents and any authenticating

agent for, and to hold them harmless against, any and all losses, liabilities, claims or expenses, including taxes (other than taxes

based upon, or measured by or determined by the income of the Trustee) incurred by it arising out of or in connection with the acceptance

or administration of its duties under this Indenture, including the costs and expenses (including reasonable fees, costs and expenses

of its agents and counsel and court costs) of enforcing this Indenture against the Company and the Guarantors (including this Section 7.06)

and defending itself against any claim (whether asserted by the Company, the Guarantors, any Holder or any other Person) or liability

in connection with the exercise or performance of any of its powers or duties hereunder, except to the extent any such loss, liability

or expense shall be caused by its gross negligence or willful misconduct, as determined by a court of competent jurisdiction in a final,

non-appealable decision. The Trustee will notify the Company promptly of any claim for which it may seek indemnity. Failure by the Trustee

to so notify the Company will not relieve the Company or any of the Guarantors of their obligations hereunder. The Company or such Guarantor

will defend the claim and the Trustee will cooperate in the defense. The Trustee may have separate counsel and the Company will pay the

reasonable fees, costs and expenses of such counsel. Neither the Company nor any Guarantor need pay for any settlement made without its

consent, which consent will not be unreasonably withheld.

secure the Company’s and the Guarantors’ payment obligations in this Section 7.06, the Trustee will have a Lien prior

to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal and interest on particular

Notes. Such Lien will survive the satisfaction and discharge of this Indenture or the earlier resignation or removal of the Trustee or

any termination of this Indenture including in connection with any bankruptcy proceeding of the Company and/or the Guarantors.

(e)            When

the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.01(8) or (9) hereof occurs,

the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute

expenses of administration under any Bankruptcy Law.

resignation or removal of the Trustee and appointment of a successor Trustee will become effective only upon the successor Trustee’s

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

Company’s expense), the Company, or the Holders of at least 10% in aggregate principal amount of the then outstanding Notes may

petition any court of competent jurisdiction for the appointment of a successor Trustee.

(e)            If

the Trustee, after written request by any Holder who has been a Holder for at least six months, fails to comply with Section 7.09

hereof, such Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor

Trustee.

(f)            A

successor Trustee will deliver a written acceptance of its appointment to the retiring Trustee and to the Company. Thereupon, the resignation

or removal of the retiring Trustee will become effective, and the successor Trustee will have all the rights, powers and duties of the

Trustee under this Indenture. The successor Trustee will send a notice of its succession to Holders. The retiring Trustee will promptly

transfer all property held by it as Trustee to the successor Trustee; provided all sums owing to the Trustee hereunder have been

paid and subject to the Lien provided for in Section 7.06 hereof. Notwithstanding replacement of the Trustee pursuant to this Section 7.07,

the Company’s obligations under Section 7.06 hereof will continue and survive for the benefit of the retiring Trustee and

will also survive the satisfaction and discharge of this Indenture and any termination of this Indenture including a termination in connection

with bankruptcy of the Company and/or the Guarantors.

to Effect Legal Defeasance or Covenant Defeasance.

The Company may, at its option and at any time,

elect to have either Section 8.02 or 8.03 hereof be applied to all outstanding Notes and Note Guarantees upon compliance with the

conditions set forth below in this Article 8.

Section 8.02         Legal

Defeasance and Discharge.

Upon the Company’s exercise under Section 8.01

hereof of the option applicable to this Section 8.02, the Company and each of the Guarantors will, subject to the satisfaction of

the conditions set forth in Section 8.04 hereof, be deemed to have been discharged from their obligations with respect to all outstanding

Notes (including the Note Guarantees) on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”).

For this purpose, Legal Defeasance means that the Company and the Guarantors will be deemed to have paid and discharged the entire Indebtedness

represented by the outstanding Notes (including the Note Guarantees), which will thereafter be deemed to be “outstanding”

only for the purposes of Section 8.05 hereof and the other Sections of this Indenture referred to in clauses (1) and (2) below,

and to have satisfied all their other obligations under such Notes, the Note Guarantees and this Indenture (and the Trustee, on demand

of and at the expense of the Company, shall execute proper instruments acknowledging the same), except for the following provisions which

will survive until otherwise terminated or discharged hereunder:

(1) the rights of Holders of outstanding

Notes to receive payments in respect of the principal of, or interest or premium, if any, on, such Notes when such payments are due from

the trust referred to in Section 8.04 hereof;

including, without limitation, those in Section 7.06 hereof; and

Defeasance.

Upon the Company’s exercise under Section 8.01

hereof of the option applicable to this Section 8.03, the Company and each of the Guarantors will, subject to the satisfaction of

the conditions set forth in Section 8.04 hereof, be released from each of their obligations under the covenants contained in Sections

4.03, 4.04, 4.05, 4.07, 4.08, 4.09, 4.10, 4.11, 4.12, 4.13, 4.14 and 4.15 hereof and clause (4) of Section 5.01 hereof with

respect to the outstanding Notes, and the Guarantors will be released from their Obligations with respect to the Note Guarantees, on

and after the date the conditions set forth in Section 8.04 hereof are satisfied (hereinafter, “Covenant Defeasance”),

and the Notes will thereafter be deemed not “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 will continue to be deemed “outstanding”

for all other purposes hereunder. For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes and Note Guarantees,

the Company and the Guarantors may omit to comply with and will 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 will not constitute

a Default or an Event of Default under Section 6.01 hereof, but, except as specified above, the remainder of this Indenture and

such Notes and Note Guarantees will be unaffected thereby. In addition, upon the Company’s exercise under Section 8.01 hereof

of the option applicable to this Section 8.03, subject to the satisfaction of the conditions set forth in Section 8.04 hereof,

Sections 6.01(3) through 6.01(7) inclusive and Section 6.01(10) hereof will not constitute Events of Default.

of any reinvestment of interest (in the case of amounts including non-callable Government Securities, in the opinion of a nationally

recognized investment bank or firm of independent public accountants), to pay the principal of, or interest and premium, if any, on the

outstanding Notes on the stated date for payment thereof or on the applicable Redemption Date, as the case may be, and any and all other

amounts due under this Indenture, and the Company must specify whether the Notes are being defeased to such stated date for payment or

to a particular Redemption Date (provided that if such redemption requires the payment of an Applicable Premium, (x) the amount

of cash in U.S. dollars, non-callable Government Securities, or a combination thereof, that must be irrevocably deposited will be determined

using an assumed Applicable Premium calculated as of the date of such deposit and (y) the depositor must irrevocably deposit or

cause to be deposited additional money (the “Applicable Premium Deficit”) in trust on the Redemption Date as necessary

to pay such Applicable Premium as determined on such date (it being understood that any defeasance shall be subject to the condition

subsequent that such Applicable Premium Deficit is in fact paid); any Applicable Premium Deficit shall be set forth in an Officer’s

Certificate delivered to the Trustee simultaneously with the deposit of such Applicable Premium Deficit that confirms that such Applicable

Premium Deficit shall be applied toward such redemption; provided, further, that the Trustee shall have no liability whatsoever in the

event that such Applicable Premium Deficit is not in fact paid after any defeasance);

(2) in the case of an election

under Section 8.02 hereof, the Company must deliver to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming

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 an election

under Section 8.03 hereof, the Company must deliver to the Trustee an Opinion of Counsel reasonably acceptable to the Trustee confirming

that, subject to customary assumptions and exclusions, the Holders 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

shall have occurred and be continuing on the date of such deposit (other than a Default or Event of Default resulting from the borrowing

of funds to be applied to such deposit (and any similar concurrent deposit relating to other Indebtedness) or the grant of Liens securing

such borrowings);

(5) such Legal Defeasance or Covenant

Defeasance will not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other than

this Indenture or any other agreement governing other Indebtedness being defeased, discharged or replaced) to which the Company or any

of its Subsidiaries is a party or by which the Company or any of its Subsidiaries is bound;

the Trustee an Officer’s Certificate and an Opinion of Counsel, each stating that all conditions precedent relating to the Legal

Defeasance or the Covenant Defeasance have been complied with.

Section 8.05         Deposited

Money and Government Securities to be Held in Trust; Other Miscellaneous Provisions.

Subject to Section 8.06 hereof, all money

and non-callable Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively

for purposes of this Section 8.05, the “Trustee”) pursuant to Section 8.04 hereof in respect of the outstanding

Notes will be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment,

either directly or through any Paying Agent (including the Company acting as Paying Agent) as the Trustee may determine, to the Holders

of such Notes of all sums due and to become due thereon in respect of principal, premium, if any, and interest but such money need not

be segregated from other funds except to the extent required by law.

The Company will pay and indemnify the Trustee

against any tax, fee or other charge imposed on or assessed against the cash or non-callable Government Securities deposited pursuant

to Section 8.04 hereof 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.

Notwithstanding anything in this Article 8

to the contrary, the Trustee will deliver or pay to the Company from time to time upon the request of the Company any money or non-callable

Government Securities held by it as provided in Section 8.04 hereof which, in the opinion of a nationally recognized firm of independent

public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04(1) hereof),

are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant

Defeasance.

Section 8.06           Repayment

to the Company.

Any money deposited with the Trustee or any Paying

Agent, or then held by the Company, in trust for the payment of the principal of, premium, if any, or interest on any Note and remaining

unclaimed for two years after such principal, premium, if any, or interest has become due and payable shall, subject to applicable escheatment

laws, be paid to the Company on its request or (if then held by the Company) will be discharged from such trust; and the Holder of such

Note will thereafter be permitted to look only to the Company for payment thereof, and all liability of the Trustee or such Paying Agent

with respect to such trust money, and all liability of the Company as trustee thereof, will thereupon cease.

Section 8.07           Reinstatement.

If the Trustee or Paying Agent is unable to apply

any U.S. dollars or non-callable Government Securities in accordance with Section 8.02 or 8.03 hereof, as the case may be, by reason

of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then

the Company’s and the Guarantors’ obligations under this Indenture and the Notes and the Note Guarantees will be revived

and reinstated as though no deposit had occurred pursuant to Section 8.02 or 8.03 hereof until such time as the Trustee or Paying

Agent is permitted to apply all such money in accordance with Section 8.02 or 8.03 hereof, as the case may be; provided,

however, that, if the Company makes any payment of principal of, premium, if any, or interest on any Note following the reinstatement

of its obligations, the Company will 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.

agreements and stipulations that may be therein contained, but the Trustee will not be obligated to enter into such amended or supplemental

indenture that affects its own rights, duties or immunities under this Indenture or otherwise.

Section 9.02         With

Consent of Holders of Notes.

Except as provided below in this Section 9.02,

the Company, the Guarantors and the Trustee may amend or supplement this Indenture (including, without limitation, Sections 3.10, 4.10

and 4.13 hereof), the Notes and the Note Guarantees with the consent of the Holders of a majority in aggregate principal amount of the

then outstanding Notes (including, without limitation, Additional Notes, if any), including, without limitation, consents obtained in

connection with a tender offer or exchange offer for, or purchase of, the Notes, and, subject to Sections 6.04 and 6.07 hereof, any existing

Default or Event of Default (other than a Default or Event of Default in the payment of the principal of, premium or interest on the

Notes, except a Payment Default resulting from an acceleration that has been rescinded) or compliance with any provision of this Indenture

or the Notes or the Note Guarantees may be waived with the consent of the Holders of a majority in aggregate principal amount of the

then outstanding Notes (including, without limitation, Additional Notes, if any), including, without limitation, consents obtained in

connection with a tender offer or exchange offer for, or purchase of, the Notes. Section 2.08 hereof shall determine which Notes

are considered to be “outstanding” for purposes of this Section 9.02. However, without the consent of each Holder affected,

an amendment, supplement or waiver under this Section 9.02 may not (with respect to any Notes held by a non-consenting Holder):

(1) reduce the principal amount

of Notes whose Holders must consent to an amendment, supplement or waiver;

(2) reduce the principal of or

change the fixed maturity of any Note or alter the provisions with respect to the redemption or repurchase of the Notes (other than provisions

relating to minimum required notice of optional redemption or the provisions of Sections 3.10 and 4.10 or Section 4.13 hereof);

(3) reduce the rate of or change

the time for payment of interest, including default interest, on any Note (other than with respect to the minimum notice period required

under Article 3);

(4) waive a Default or Event of

Default in the payment of principal of, or interest or premium, if any, on the Notes (except a rescission of acceleration of the Notes

by the Holders of a majority in aggregate principal amount of the then outstanding Notes and a waiver of the payment default that resulted

from such acceleration);

(5) make any Note payable in money

other than that stated in the Notes;

(6) make any change in the provisions

of this Indenture relating to waivers of past Defaults or the rights of Holders of Notes to receive payments of, principal of, or interest

or premium, if any, on, the Notes (other than as permitted by clause (7) below);

(7) waive a redemption or repurchase

payment with respect to any Note (other than a payment required by Sections 3.10 and 4.10 or Section 4.13 hereof);

(8) release any Guarantor from

any of its obligations under its Note Guarantee or this Indenture, except in accordance with the terms of this Indenture; or

(9) make any change in the preceding

amendment, supplement and waiver provisions.

Upon the request of the Company and upon the filing

with the Trustee of evidence satisfactory to the Trustee of the consent of the Holders of Notes as aforesaid, and upon receipt by the

Trustee of the documents described in Section 9.05 hereof, the Trustee will join with the Company and the Guarantors in the execution

of such amended or supplemental indenture unless such amended or supplemental indenture directly affects the Trustee’s own rights,

duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but will not be obligated to,

enter into such amended or supplemental Indenture.

It is not necessary for the consent of the Holders

of Notes under this Section 9.02 to approve the particular form of any proposed amendment, supplement or waiver, but it is sufficient

if such consent approves the substance thereof.

After an amendment, supplement or waiver under

this Section 9.02 becomes effective, the Company will send to the Holders of Notes affected thereby a notice briefly describing

the amendment, supplement or waiver. Any failure of the Company to send such notice, or any defect therein, will not, however, in any

way impair or affect the validity of any such amended or supplemental indenture or waiver.

Section 9.03         Revocation

and Effect of Consents.

Until an amendment, supplement or waiver becomes

effective, a consent to it by a Holder of a Note is a continuing consent by the Holder of a Note and every subsequent Holder of a Note

or portion of a Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made

on any Note. However, any such Holder of a Note or subsequent Holder of a Note may revoke the consent as to its Note if the Trustee receives

written notice of revocation before the date the amendment, supplement or waiver becomes effective. An amendment, supplement or waiver

becomes effective in accordance with its terms (except as provided in the second succeeding paragraph) and thereafter binds every Holder.

The Company may, but shall not be obligated to,

fix a record date for the purpose of determining the Holders entitled to consent to any amendment, supplement or waiver. If a record

date is fixed, then notwithstanding the second to last sentence of the immediately preceding paragraph, those Persons who were Holders

at such record date (or their duly designated proxies) and only those Persons, shall be entitled to consent to such amendment or waiver

or revoke any consent previously given, whether or not such Persons continue to be Holders after such record date.

After an amendment, supplement or waiver becomes

effective, it shall bind every Holder, unless it makes a change described in any of the clauses (1) through (9) of Section 9.02,

in which case, the amendment, supplement or waiver shall bind only each Holder of a Note who has consented to it and every subsequent

Holder of a Note or portion of a Note that evidences the same indebtedness as the consenting Holder’s Note.

Section 9.04         Notation

on or Exchange of Notes.

The Trustee may place an appropriate notation

about an amendment, supplement or waiver on any Note thereafter authenticated. The Company in exchange for all Notes may issue and the

Trustee shall, upon receipt of an Authentication Order, authenticate new Notes that reflect the amendment, supplement or waiver.

Failure to make the appropriate notation or issue

a new Note will not affect the validity and effect of such amendment, supplement or waiver.

Section 9.05         Trustee

to Sign Amendments, etc.

The Trustee will sign any amended or supplemental

indenture authorized pursuant to this Article 9 if the amendment or supplement does not adversely affect the rights, duties, liabilities

or immunities of the Trustee. In executing any amended or supplemental indenture, the Trustee will be entitled to receive and (subject

to Section 7.01 hereof) will be fully protected in relying upon, in addition to the documents required by Section 12.03 hereof,

an Officer’s Certificate and an Opinion of Counsel stating that the execution of such amended or supplemental indenture is authorized

or permitted by this Indenture and that such supplemental indenture constitutes the legal, valid and binding obligation of the Company

and the Guarantors subject to customary exceptions.

Section 9.06         Effect

of Supplemental Indentures.

Upon the execution of any supplemental indenture

under this Article 9, this Indenture shall be modified in accordance therewith, and such supplemental indenture shall form a part

of this Indenture for all purposes; and every Holder of Notes theretofore or thereafter authenticated and delivered hereunder shall be

bound thereby.

ARTICLE 10

NOTE GUARANTEES

Section 10.01         Guarantee.

(a)            Subject

to this Article 10, each of the Guarantors hereby, jointly and severally, guarantees to each Holder of a Note authenticated and

delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture,

the Notes or the obligations of the Company hereunder or thereunder, that:

(1) the principal of, premium,

if any, and interest on, the Notes will be promptly paid in full when due, whether at Stated Maturity, by acceleration, redemption or

otherwise, and interest on the overdue principal of and interest on the Notes, if any, if lawful, and all other obligations of the Company

to the Holders or the Trustee hereunder or thereunder will be promptly 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 any of such other obligations, that same will be promptly 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.

Failing payment when due of any amount so guaranteed

or any performance so guaranteed for whatever reason, the Guarantors will be jointly and severally obligated to pay the same immediately.

Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection.

(b)            The

Guarantors hereby agree that their obligations hereunder are 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 of the Notes with

respect to any provisions hereof or thereof, the recovery of any judgment against the Company, 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

diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Company, any

right to require a proceeding first against the Company, protest, notice and all demands whatsoever and covenants that its Note Guarantee

will not be discharged except by complete performance of the obligations contained in the Notes and this Indenture.

any Holder or the Trustee is required by any court or otherwise to return to the Company, the Guarantors or any custodian, trustee, liquidator

or other similar official acting in relation to either the Company or the Guarantors, any amount paid by either to the Trustee or such

Holder, each Note Guarantee, to the extent theretofore discharged, will be reinstated in full force and effect.

(d)            Each

Guarantor agrees that it will not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed

hereby until payment in full of all obligations guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on

the one hand, and the Holders and the Trustee, on the other hand, (1) the maturity of the obligations guaranteed hereby may be accelerated

as provided in Article 6 hereof for the purposes of this Section 10.01, notwithstanding any stay, injunction or other prohibition

preventing such acceleration in respect of the obligations guaranteed hereby, and (2) in the event of any declaration of acceleration

of such obligations as provided in Article 6 hereof, such obligations (whether or not due and payable) will forthwith become due

and payable by the Guarantors for the purposes of this Section 10.01. The Guarantors will have the right to seek contribution from

any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Note Guarantee.

Section 10.02         Limitation

on Guarantor Liability.

Each Guarantor, and by its acceptance of Notes,

each Holder, hereby confirm that it is the intention of all such parties that the Note Guarantee of such Guarantor not constitute a fraudulent

transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or

any similar federal or state law to the extent applicable to any Note Guarantee. To effectuate the foregoing intention, the Trustee,

the Holders and the Guarantors hereby irrevocably agree that the obligations of such Guarantor will be limited to the maximum amount

that will, after giving effect to such maximum amount and all other contingent and fixed liabilities of such Guarantor that are relevant

under such laws, and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf

of any other Guarantor in respect of the obligations of such other Guarantor under this Article 10, result in the obligations of

such Guarantor under its Note Guarantee not constituting a fraudulent transfer or conveyance.

Section 10.03         Execution

and Delivery of Notation of Note Guarantee.

To evidence its Note Guarantee and of all the

Obligations under this Indenture set forth in Section 10.01 hereof, each Guarantor hereby agrees that a notation of such Note Guarantee

substantially in the form attached as Exhibit D hereto will be endorsed by an Officer of such Guarantor on each Note authenticated

and delivered by the Trustee (provided that no such notation will be required with respect to any Note authenticated prior to

the time a Guarantor becomes a Guarantor) and that this Indenture (including any supplement thereto) will be executed on behalf of such

Guarantor by one of its Officers.

Each Guarantor hereby agrees that its Note Guarantee

and its guarantee of all of the Obligations under this Indenture set forth in Section 10.01 hereof will remain in full force and

effect notwithstanding any failure to endorse on each Note a notation of such Note Guarantee.

If an Officer whose signature is on this Indenture

or on the notation of its Note Guarantee no longer holds that office at the time the Trustee authenticates the Note on which such notation

of its Note Guarantee is endorsed, the Note Guarantee will be valid nevertheless.

The delivery of any Note by the Trustee, after

the authentication thereof hereunder, will constitute due delivery of the Note Guarantee set forth in this Indenture on behalf of the

Guarantors.

In the event that the Company or any of the Company’s

Restricted Subsidiaries creates or acquires any wholly-owned Restricted Subsidiary after the date of this Indenture, if required by Section 4.14

hereof, the Company will cause such Restricted Subsidiary to comply with the provisions of Section 4.14 hereof and this Article 10,

to the extent applicable.

Section 10.04         Guarantors

May Consolidate, etc., on Certain Terms.

Except as otherwise provided in Section 10.05

hereof, a Guarantor may not sell or otherwise dispose of all or substantially all of its properties or assets to, or consolidate with

or merge with or into (whether or not such Guarantor is the surviving Person) another Person, other than the Company or another Guarantor,

unless:

(a)            immediately

after giving effect to such transaction, no Default or Event of Default exists; and

(b)            either:

(1) the Person acquiring the properties

or assets in any such sale or disposition or the Person formed by or surviving any such consolidation or merger is a Guarantor, or assumes

all the obligations of that Guarantor under this Indenture and its Note Guarantee, pursuant to a supplemental indenture in form reasonably

satisfactory to the Trustee; or

(2) the transaction does not violate

Section 4.10 of this Indenture.

In case of any such consolidation, merger, sale

or other disposition and upon the assumption by the successor Person, by supplemental indenture, executed and delivered to the Trustee

and reasonably satisfactory in form to the Trustee, of such obligations of the Guarantor, such successor Person will succeed to and be

substituted for the Guarantor with the same effect as if it had been named herein as a Guarantor. Such successor Person thereupon may

cause to be signed any or all of the notations of Note Guarantees to be endorsed upon all of the Notes issuable hereunder which theretofore

shall not have been signed by the Company and delivered to the Trustee. The Note Guarantee so issued by such successor Person will in

all respects have the same legal rank and benefit under this Indenture as the Note Guarantees theretofore and thereafter issued in accordance

with the terms of this Indenture as though such Note Guarantee had been issued at the date of the execution hereof.

Section 10.05         Releases.

A Guarantor will be automatically and unconditionally

released, discharged and relieved of any obligations under its Note Guarantee and all of its other Obligations under this Indenture without

any further action by the Company, the relevant Guarantor or the Trustee:

(a)            in

the event of any sale or other disposition (i) of all or substantially all of the properties or assets of such Guarantor (including

by way of merger or consolidation) to a Person that is not (either before or after giving effect to such transactions) the Company or

a Restricted Subsidiary of the Company, or (ii) of Capital Stock of such Guarantor after which the applicable Guarantor is no longer

a Restricted Subsidiary of the Company; provided that any such sale or other disposition does not violate the applicable provisions

of Section 4.10 hereof;

(b)            upon

designation of such Guarantor as an Unrestricted Subsidiary in accordance with the terms of this Indenture;

such time as such Guarantor ceases to guarantee any other Indebtedness of the Company under a Credit Facility such that it would not,

if not a Guarantor, be required to become a Guarantor under Section 4.14 hereof, or (ii) with respect to any Guarantor that

provided a Note Guarantee not required pursuant to the terms of this Indenture, at any time at the sole discretion of the Company;

(d)            upon

Legal Defeasance or Covenant Defeasance in accordance with Article 8 hereof or satisfaction and discharge of this Indenture in accordance

with Article 11 hereof; or

(e)            upon

the merger or consolidation of such Guarantor with and into the Company or another Guarantor that is the surviving Person in such merger

or consolidation, or upon the liquidation or dissolution of such Guarantor.

Upon delivery by the Company to the Trustee of an Officer’s

Certificate and an Opinion of Counsel to the effect that the conditions of this Section 10.05 for a release have been satisfied,

the Trustee will execute any documents reasonably required in order to evidence the release of any Guarantor from its obligations under

its Note Guarantee and all of its other Obligations under this Indenture.

Any Guarantor not released from its obligations under its

Note Guarantee and all of its other Obligations under this Indenture as provided in this Section 10.05 will remain liable for the

full amount of principal of and interest, and premium, if any, on the Notes and for the other Obligations of such Guarantor under this

Indenture as provided in this Article 10.

In addition, the Company will have the right, upon delivery of an

Officer’s Certificate to the Trustee, to cause any Guarantor that does not guarantee any Indebtedness under any Credit Facility

of the Company or Guarantor, and is not otherwise required by the applicable terms of this Indenture, to provide a Guarantee, to be unconditionally

released and discharged from all obligations under its Guarantee, and such Guarantee will thereupon automatically and unconditionally

terminate and be discharged and of no further force or effect.

ARTICLE 11

satisfaction and discharge

Section 11.01         Satisfaction

and Discharge.

This Indenture will be discharged and will cease

to be of further effect as to all Notes issued hereunder (except as to surviving rights of registration of transfer or exchange of the

Notes and as otherwise specified in this Article 11), when:

(1) either:

(A)            all

Notes that have been authenticated, except lost, stolen or destroyed Notes that have been replaced or paid and Notes for whose payment

money has been deposited in trust and thereafter repaid to the Company, have been delivered to the Trustee for cancellation; or

100

(B)            all

Notes that have not been delivered to the Trustee for cancellation have become due and payable or will become due and payable within

one year by reason of the sending of a notice of redemption or otherwise, and the Company or any Guarantor has irrevocably deposited

or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders, cash in U.S. dollars, non-callable

Government Securities, or a combination of cash in U.S. dollars and non-callable Government Securities, in amounts as will be sufficient,

without consideration of any reinvestment of interest, in the opinion of a nationally recognized investment bank, valuation or firm of

independent public accountants solely to the extent the deposit includes any Government Securities and solely with respect to such amount

of Government Securities, to pay and discharge the entire Indebtedness on the Notes not delivered to the Trustee for cancellation for

principal, premium, if any, and accrued interest, if any, to the date of Stated Maturity or redemption (provided that if such redemption

requires the payment of any Applicable Premium, (x) the amount of cash in U.S. dollars, non-callable Government Securities, or a

combination thereof, that must be irrevocably deposited will be determined using an assumed Applicable Premium calculated as of the date

of such deposit and (y) the depositor must irrevocably deposit or cause to be deposited the Applicable Premium Deficit in trust

on the Redemption Date as necessary to pay such Applicable Premium as determined by such date; any Applicable Premium Deficit shall be

set forth in an Officer’s Certificate delivered to the Trustee simultaneously with the deposit of such Applicable Premium Deficit

that confirms that such Applicable Premium Deficit shall be applied toward such redemption; provided, further, that the Trustee shall

have no liability whatsoever in the event that such Applicable Premium Deficit is not in fact paid after any satisfaction and discharge);

(2) the Company or any Guarantor

has paid or caused to be paid all sums payable by it under this Indenture, including without limitation any and all amounts due and owing

to the Trustee; and

(3) the Company has delivered irrevocable

instructions to the Trustee under this Indenture to apply the deposited money toward the payment of the Notes at Stated Maturity or on

the Redemption Date, as the case may be.

In addition, the Company must deliver (a) an Officer’s

Certificate stating that all conditions precedent set forth in clauses (1) through (3) above have been satisfied, and (b) an

Opinion of Counsel to the Trustee (which Opinion of Counsel may be subject to customary assumptions and qualifications), stating that

all conditions precedent to satisfaction and discharge set forth in Section 11.01(3) have been satisfied.

Notwithstanding the satisfaction and discharge

of this Indenture, if money has been deposited with the Trustee pursuant to subclause (B) of clause (1) of this Section 11.01,

the provisions of Sections 11.02 and 8.06 hereof will survive. In addition, nothing in this Section 11.01 will be deemed to discharge

those provisions of Section 7.06 hereof, that, by their terms, survive the satisfaction and discharge of this Indenture.

Section 11.02         Application

of Trust Money.

Subject to the provisions of Section 8.06

hereof, all money deposited with the Trustee pursuant to Section 11.01 hereof 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 Company

acting as Paying Agent) as the Trustee may determine, to the Persons entitled thereto, of the principal (and premium, if any) and interest

for whose payment such money has been deposited with the Trustee; but such money need not be segregated from other funds except to the

extent required by law.

101

If the Trustee or Paying Agent is unable to apply

any money or Government Securities in accordance with Section 11.01 hereof 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 Company’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 11.01 hereof until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance

with Section 11.01; provided that if the Company has made any payment of principal of, premium, if any, or interest on any

Notes because of the reinstatement of their obligations, the Company 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.

The Company will pay and indemnify the Trustee

against any tax, fee or other charge imposed on or assessed against the cash or non-callable Government Securities deposited pursuant

to Section 11.01 hereof 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.

Capitalized terms used herein have the meanings

assigned to them in the Indenture referred to below unless otherwise indicated.

principal amount of this Note at 7.625% per annum. The Company will pay interest semi-annually in arrears on May 1 and November 1

of each year, or if any such day is not a Business Day, on the next succeeding Business Day, provided that the final interest

payment will be due on November 1, 2034 (each, an “Interest Payment Date”); provided, further that the

first Interest Payment Date shall be May 1, 2027. Interest on the Notes will accrue from the most recent date to which interest

has been paid or, if no interest has been paid, from the date of issuance; provided that if there is no existing Default in the

payment of interest, and if this Note is authenticated between a record date referred to on the face hereof and the next succeeding Interest

Payment Date, interest shall accrue from such next succeeding Interest Payment Date. Interest will be computed on the basis of a 360-day

year of twelve 30-day months. If any payment with respect to any principal of, premium, if any, on, or interest, if any, on any Notes

(including any payment to be made on any date fixed for redemption or purchase of any Note) is due on a day which is not a Business Day,

then the payment need not be made on such date, but may be made on the next Business Day with the same force and effect as if made on

such date, and no interest will accrue for the intervening period.

(2)            Method

of Payment. The Company will pay interest on the Notes (except defaulted interest) to the Persons who are registered Holders

of Notes at the close of business on the April 15 or October 15 next preceding the Interest Payment Date, even if such Notes

are canceled after such record date and on or before such Interest Payment Date, except as provided in Section 2.12 of the Indenture

with respect to defaulted interest. The Notes will be payable as to principal, premium and interest at the office or agency of the Company

maintained for such purpose, or, at the option of the Company, payment of interest may be made by check mailed to the Holders at their

addresses set forth in the register of Holders; provided that payment by wire transfer of immediately available funds will be

required with respect to principal of and interest and premium on, all Global Notes and all other Notes to Holders having an aggregate

principal amount of Notes more than $5.0 million, the Holders of which will have provided wire transfer instructions not later than the

relevant record date to the Company or the Paying Agent to that Holder’s U.S. dollar account within the contiguous United States.

The Company will pay the principal of, and interest on, Notes in global form registered in the name of or held by The Depository Trust

Company (“DTC”) or its nominee in immediately available funds to DTC or its nominee, as the case may be, as the registered

Holder of such Global Notes. Such payment will be in such coin or currency of the United States of America as at the time of payment

is legal tender for payment of public and private debts.

Supplement and Waiver. Subject to certain exceptions, the Indenture or the Notes or the Note Guarantees may be amended or

supplemented with the consent of the Holders of a majority in aggregate principal amount of the then outstanding Notes including Additional

Notes, if any, and any existing Default or Event of Default or compliance with any provision of the Indenture or the Notes or the Note

Event of Default arising from certain events of bankruptcy or insolvency with respect to the Company or any Restricted Subsidiary of

the Company that is a Significant Subsidiary or any group of Restricted Subsidiaries of the Company that, taken together, would constitute

a Significant Subsidiary, the principal of, and accrued and unpaid interest, if any, on all outstanding Notes will become due and payable

immediately without further action or notice. Subject to certain limitations, Holders of a majority in aggregate principal amount of

the then outstanding Notes may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of the

Notes notice of any continuing Default or Event of Default if it determines that withholding notice is in their interest, except a Default

or Event of Default relating to the payment of principal, interest, or premium, if any, on any Note. The Holders of a majority in aggregate

principal amount of the then outstanding Notes by notice to the Trustee may, on behalf of the Holders of all of the Notes, rescind an

acceleration or waive any existing Default or Event of Default and its consequences under the Indenture except a continuing Default or

Event of Default in the payment of interest or premium, if any, on, or the principal of, the Notes. The Company and the Guarantors are

required to deliver to the Trustee annually a statement regarding compliance with the Indenture, and the Company and the Guarantors are

required, within five Business Days of becoming aware of any Default or Event of Default, to deliver to the Trustee a statement specifying

such Default or Event of Default and what action the Company is taking or proposes to take with respect thereto, other than to the extent

such Default or Event of Default has been cured.

(14)            Trustee

Dealings with the Company. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from,

and perform services for the Company or its Affiliates, and may otherwise deal with the Company or its Affiliates, as if it were not

the Trustee.

(15)            No

Recourse Against Others. A director, officer, partner, member, employee, incorporator, manager or unit holder or other owner

of Equity Interest of the Company, any Guarantor or the Parent, as such, will not have any liability for any obligations of the Company,

the Guarantors or the Parent under the Notes, the Indenture, the Note Guarantees or for any claim based on, in respect of, or by reason

of, such obligations or their creation. Each Holder of Notes by accepting a Note waives and releases all such liability. The waiver and

release are part of the consideration for the issuance of the Notes and the Note Guarantees.

A-6

(16)            Authentication.

This Note will not be valid until authenticated by the manual signature of the Trustee or an authenticating agent.

(17)            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 not as tenants in common), CUST (= Custodian), and U/G/M/A

(= Uniform Gifts to Minors Act).

(18)            CUSIP

Numbers. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Company

has caused CUSIP numbers to be printed on the Notes, and the Trustee may use CUSIP numbers in notices of redemption 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

of redemption, and reliance may be placed only on the other identification numbers placed thereon.

(19)            GOVERNING
