W I T N E S S E T H:

WHEREAS, the Company has duly authorized the issuance from time to time of its debentures, notes, bonds or other evidences of indebtedness (the “Securities”), which are to be issued in one or more series, and the Company and the Subsidiary Guarantors have heretofore made, executed and delivered to the Trustee an Indenture dated as of January 19, 2018 (the “Original Indenture”) pursuant to which the Securities are issuable;

WHEREAS, Sections 2.01, 2.03 and 9.01 of the Original Indenture provide that the form or terms of any series of Securities may be established in a supplemental indenture, and the Company desires to establish in this First Supplemental Indenture both the form and terms of a separate series of Securities designated as its 3.95% Senior Notes due 2028 (the “Notes”); and

WHEREAS, all things necessary to authorize the execution and delivery of this First Supplemental Indenture, to establish the Notes as provided for in this First Supplemental Indenture, and to make the Original Indenture, as supplemented with respect to the Notes by this First Supplemental Indenture and as it may otherwise be supplemented thereafter with applicability to the Notes (the Original Indenture, as so supplemented, being sometimes referred to herein as the “Indenture”), a valid agreement of the Company and the Subsidiary Guarantors, in accordance with its terms, have been done;

ARTICLE I

SUPPLEMENT OF THE ORIGINAL INDENTURE

SECTION 1.01

Supplement to Article I of the Original Indenture.

(a) Section 1.01 of the Original Indenture is supplemented or superseded with respect to the Notes, in the case of definitional paragraphs that may be inconsistent, by inserting therein, in alphabetical order, the following definitional paragraphs:

“Additional Interest” means the additional interest that shall accrue on the Notes in accordance with the terms of a Registration Rights Agreement if a Registration Default (as defined in the applicable Registration Rights Agreement) occurs.

“Adjusted Treasury Rate” means, with respect to any Redemption Date, the rate per annum equal to: (1) the yield, under the heading that represents the average for the immediately preceding week, appearing in the most recently published statistical release

designated “H.15(519)” or any successor publication that is published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded U.S. Treasury securities, adjusted to constant maturity under the caption “Treasury Constant Maturities” for the maturity corresponding to the Optional Redemption Comparable Treasury Issue; provided that, if no maturity is within three months before or after the remaining term of the Notes, yields for the two published maturities most closely corresponding to the Optional Redemption Comparable Treasury Issue will be determined and the Adjusted Treasury Rate will be interpolated or extrapolated from such yields on a straight line basis, rounding to the nearest month; or (2) if such release (or any successor release) is not published during the week preceding the calculation date or does not contain such yields, the rate per annum equal to the semiannual equivalent yield to maturity of the Optional Redemption Comparable Treasury Issue, calculated using a price for the Optional Redemption Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Optional Redemption Comparable Treasury Price for such Redemption Date. The Company (or its designee) will (a) determine the Adjusted Treasury Rate and the Make-Whole Redemption Price with respect to any redemption on the third Business Day prior to the Redemption Date, and (b) prior to such Redemption Date file with the Trustee an Officers’ Certificate setting forth the Adjusted Treasury Rate and the Make-Whole Redemption Price and showing the calculation of such in reasonable detail.

“Attributable Debt” means, with respect to any Sale and Lease-Back Transaction as of any particular time, the present value discounted at the rate of interest implicit in the terms of the lease of the obligations of the lessee under such lease for net rental payments during the remaining term of the lease.

“Credit Agreement” means that certain Credit Agreement, dated as of September 27, 2012, by and among the Company, ▇▇▇▇▇ Fargo Bank, N.A., as administrative agent, an l/c issuer, swing line lender and a lender and the other lender parties thereto, as amended, restated, replaced, or refinanced from time to time, whether with the same or different lenders.

(iv) the instructions that a holder must follow in order to have its Notes purchased.

(c) Holders of Notes electing to have Notes purchased pursuant to a Change of Control Offer will be required to surrender their Notes, with the form entitled “Option of Holder to Elect Purchase” on the reverse of the Note completed, to the Paying Agent at the address specified in the notice, or transfer their Notes to the Paying Agent by book-entry transfer pursuant to the applicable procedures of the Paying Agent and the Depositary, prior to the close of business on the third Business Day prior to the Change of Control Payment Date.

(d) The Company may make a Change of Control Offer in advance of a Change of Control, and the Company’s Change of Control Offer may be conditioned upon the consummation of such Change of Control, if a definitive agreement is in place for the Change of Control at the time of making the Change of Control Offer.

purchase at a Redemption Price in cash equal to 101% of the principal amount thereof, 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 on the relevant Interest Payment Date). Any such redemption pursuant to this Section 2.07(e) shall be made in accordance with Article III of the Original Indenture.

(f) The Company shall not be required to make a Change of Control Offer if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for such an offer made by the Company and such third party purchases all Notes properly tendered and not withdrawn under its offer.

(h) The Holders of a majority in principal amount of the outstanding Notes may, on behalf of the Holders of all Notes and in accordance with Article IX of the Original Indenture, amend or waive the right of the Holders to require the Company to purchase all or any part of each Holder’s Notes as a consequence of a Change of Control Triggering Event.

2.1 The Notes.

(a) Form and Dating. Initial Notes offered and sold to QIBs in reliance on Rule 144A under the Securities Act (“Rule 144A”) (“Rule 144A Global Notes”) shall be issued initially in the form of one or more permanent Global Notes, and Notes offered and sold in reliance on Regulation S under the Securities Act (“Regulation S”) shall be issued initially in the form of one or more temporary Global Notes (“Temporary Regulation S Global Notes”), in each case with the applicable Restricted Legend (each security, unless and until becoming an Unrestricted Note, a “Restricted Global Note”). Additional Notes offered and sold to QIBs in reliance on Rule 144A shall be issued initially in the form of one or more permanent Rule 144A Global Notes, and Additional Notes offered and sold in reliance on Regulation S shall be issued initially in the form of one or more Temporary Regulation S Global Notes or Permanent Regulation S Global Notes, in each case, with the applicable Restricted Legend. Exchange Notes shall be issued (i) in the form of one or more permanent Global Notes or (ii) in the form of Definitive Notes as provided in Section 2.4.

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

Except as set forth in this Section 2.1(b), beneficial interests in a Temporary Regulation S Global Note will not be exchangeable for interests in a Rule 144A Global Note, a permanent global note (the “Permanent Regulation S Global Note” and, together with the Temporary Regulation S Global Note, the “Regulation S Global Note”) or any other Note prior to the expiration of the period through and including the 40th day after the later of the commencement of the offering of the Initial Notes or Additional Notes represented by such Temporary Regulation S Global Note and the closing of such offering (such period, the “Restricted Period”).

Prior to the expiration of the Restricted Period, beneficial interests in a Temporary Regulation S Global Note may be exchanged for beneficial interests in the Rule 144A Global Note only if (i) such exchange occurs in connection with a transfer of the Notes pursuant to Rule 144A, (ii) the transferor first delivers to the Trustee a written certificate to the effect that the beneficial interest in the Temporary Regulation S Global Note is being transferred to a Person who the transferor reasonably believes to be a QIB and is purchasing for its own account or the account of a QIB, in each case in a transaction meeting the requirements of Rule 144A, and (iii) the transfer is in accordance with all applicable securities laws of the states of the United States and other jurisdictions. After the expiration of the Restricted Period, such certification requirements shall not apply to such transfers of beneficial interests in a Restricted Global Note representing Regulation S Global Notes.

Beneficial interests in a Restricted Global Note representing Rule 144A Global Notes may be transferred to a Person who takes delivery in the form of an interest in the

Appendix-2

Regulation S Global Note, whether before or after the expiration of the Restricted Period, only if the transferor first delivers to the Trustee a written certificate to the effect that such transfer is being made in accordance with Rule 903 or 904 of Regulation S or Rule 144 (if available).

(c) Definitive Notes. Except as provided in Section 2.3 or 2.4, owners of beneficial interests in Restricted Global Notes shall not be entitled to receive Definitive Notes. Definitive Notes shall be exchangeable for beneficial interests in Global Securities only as provided in Section 2.4.

2.2 Authentication of Exchange Notes. Upon the consummation of a Registered Exchange Offer with respect to Transfer Restricted Notes and delivery of a Company Order, the Trustee shall authenticate and deliver Exchange Notes for issue in a Registered Exchange Offer pursuant to a Registration Rights Agreement for a like principal amount of Transfer Restricted Notes. Concurrently with the issuance of such Exchange Notes, the Trustee shall cause the aggregate principal amount of the Transfer Restricted Notes to be reduced accordingly.

2.3 Transfer and Exchange.

(a) Transfer and Exchange of Global Notes. The transfer and exchange of Global Notes or beneficial interests therein shall be effected through the Depositary, in accordance with the Indenture (including applicable restrictions on transfer set forth herein, if any).

In the event that a Restricted Global Note is exchanged for Definitive Notes pursuant to Section 2.4 prior to the consummation of a Registered Exchange Offer or the effectiveness of a Shelf Registration Statement with respect to such Notes, such Notes may be exchanged only in accordance with such procedures as are substantially consistent with the provisions of this Section 2.3 (including the certification requirements set forth on the reverse of the Transfer Restricted Notes intended to ensure that such transfers comply with Rule 144A or Regulation S or another applicable exemption under the Securities Act, as the case may be).

(b) Transfer and Exchange of Definitive Notes. When Definitive Notes are presented to the Registrar with a request (x) to register the transfer of such Definitive Notes or (y) to exchange such Definitive Notes for an equal principal amount of Definitive Notes of other authorized denominations, the Registrar shall register the transfer or make the exchange as requested if its requirements for such transaction are met; provided, however, that if such Definitive Notes surrendered for transfer or exchange are required to bear a Restricted Legend, then they are being transferred or exchanged pursuant to an effective registration statement under the Securities Act, pursuant to Section 2.3(c) or pursuant to clause (A), (B) or (C) below, and are accompanied by the following additional information and documents, as applicable:

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

(B) if such Definitive Notes are being transferred to the Company, a Subsidiary Guarantor or any Subsidiary thereof, a certification to that effect; or

Appendix-3

(C) if such Definitive Notes are being transferred (x) pursuant to an exemption from registration in accordance with Rule 144A or Regulation S under the Securities Act; or (y) in reliance upon another exemption from the requirements of the Securities Act: (I) a certification to that effect and (II) if the Company or the Trustee so requests in connection with a transfer in accordance with Regulation S during the Restricted Period or a transfer pursuant to clause (y), an opinion of counsel or other evidence reasonably satisfactory to it as to the compliance with the restrictions set forth in the applicable Restricted Legend.

(i) Except as permitted by the following subclauses (ii), (iii), (iv) and (v), each Note certificate evidencing the Restricted Global Notes (and all Notes issued in exchange therefor or in substitution thereof) shall bear a legend in substantially the following form (the “Restricted Legend”):

For each Rule 144A Global Note and each Regulation S Global Note:

Appendix-4

REGISTRATION STATEMENT THAT HAS BEEN DECLARED EFFECTIVE UNDER THE U.S. SECURITIES ACT, (C) FOR SO LONG AS THE SECURITIES ARE ELIGIBLE FOR RESALE PURSUANT TO RULE 144A, TO A PERSON IT REASONABLY BELIEVES IS A QUALIFIED INSTITUTIONAL BUYER THAT PURCHASES FOR ITS OWN ACCOUNT OR FOR THE ACCOUNT OF A QUALIFIED INSTITUTIONAL BUYER TO WHOM NOTICE IS GIVEN THAT THE TRANSFER IS BEING MADE IN RELIANCE ON RULE 144A, OR (D) PURSUANT TO OFFERS AND SALES TO PERSONS WHO ARE NOT U.S. PERSONS THAT OCCUR OUTSIDE THE UNITED STATES IN COMPLIANCE WITH REGULATION S UNDER THE U.S. SECURITIES ACT, OR (E) PURSUANT TO ANY OTHER AVAILABLE EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE U.S. SECURITIES ACT, SUBJECT IN EACH OF THE FOREGOING CASES TO ANY REQUIREMENT OR LAW THAT THE DISPOSITION OF ITS PROPERTY OR THE PROPERTY OF SUCH INVESTOR ACCOUNT OR ACCOUNTS BE AT ALL TIMES WITHIN ITS OR THEIR CONTROL AND IN COMPLIANCE WITH ANY APPLICABLE STATE SECURITIES LAWS AND ANY APPLICABLE LOCAL LAWS AND REGULATIONS AND (3) AGREES THAT IT WILL GIVE TO EACH PERSON TO WHOM THIS SECURITY IS TRANSFERRED A NOTICE SUBSTANTIALLY TO THE EFFECT OF THIS LEGEND; PROVIDED, THAT THE COMPANY AND THE TRUSTEE SHALL HAVE THE RIGHT PRIOR TO ANY SUCH OFFER, SALE OR TRANSFER (I) PURSUANT TO CLAUSE (D) PRIOR TO THE RESALE RESTRICTION TERMINATION DATE OR PURSUANT TO CLAUSE (E) TO REQUIRE THE DELIVERY OF AN OPINION OF COUNSEL, CERTIFICATION OR OTHER INFORMATION SATISFACTORY TO EACH OF THEM AND (II) IN EACH OF THE FOREGOING CASES, TO REQUIRE THAT A CERTIFICATE OF TRANSFER IN THE FORM APPEARING ON THE REVERSE OF THIS SECURITY IS COMPLETED AND DELIVERED BY THE TRANSFEROR TO THE TRUSTEE.

THE HOLDER OF THIS SECURITY BY ITS ACCEPTANCE HEREOF WILL BE DEEMED TO HAVE REPRESENTED AND WARRANTED THAT EITHER (1) NO PORTION OF THE ASSETS USED BY SUCH HOLDER TO ACQUIRE OR HOLD THIS SECURITY CONSTITUTES THE ASSETS OF AN EMPLOYEE BENEFIT PLAN THAT IS SUBJECT TO TITLE I OF THE U.S. EMPLOYEE RETIREMENT INCOME SECURITY ACT OF 1974, AS AMENDED (“ERISA”), OF A PLAN, INDIVIDUAL RETIREMENT ACCOUNT OR OTHER ARRANGEMENT THAT IS SUBJECT TO SECTION 4975 OF THE U.S. INTERNAL REVENUE CODE OF 1986, AS AMENDED (THE “CODE”), OR PROVISIONS UNDER ANY OTHER FEDERAL, STATE, LOCAL, NON-U.S. OR OTHER LAWS OR REGULATIONS THAT ARE SIMILAR TO SUCH PROVISIONS OF ERISA OR THE CODE (“SIMILAR LAWS”), OR OF AN ENTITY WHOSE UNDERLYING ASSETS ARE CONSIDERED TO INCLUDE “PLAN ASSETS” OF ANY SUCH PLAN, ACCOUNT OR ARRANGEMENT, (2) THE ACQUISITION AND HOLDING OF THIS SECURITY WILL NOT CONSTITUTE A NON-EXEMPT PROHIBITED TRANSACTION UNDER SECTION 406 OF ERISA OR SECTION 4975 OF THE CODE OR A SIMILAR VIOLATION UNDER ANY APPLICABLE SIMILAR LAWS OR (3) NO ADVICE PROVIDED BY US OR ANY OF OUR AFFILIATES HAS FORMED A PRIMARY BASIS FOR MAKING ANY INVESTMENT OR OTHER DECISION FOR OR ON BEHALF OF SUCH PLAN IN CONNECTION WITH THE NOTES OR THE EXERCISE OF ANY RIGHTS WITH RESPECT TO THE NOTES.

Appendix-5

Each Temporary Regulation S Global Note shall also bear the following legend:

THE RIGHTS ATTACHING TO THIS TEMPORARY REGULATION S GLOBAL NOTE, AND THE CONDITIONS AND PROCEDURES GOVERNING (I) THE EXCHANGE OF BENEFICIAL INTERESTS IN THIS TEMPORARY REGULATION S GLOBAL NOTE FOR INTERESTS IN THE PERMANENT REGULATION S GLOBAL NOTE OR RULE 144A GLOBAL NOTE AND (II) THE TRANSFER OF INTERESTS IN THIS TEMPORARY REGULATION S GLOBAL NOTE, ARE AS SPECIFIED IN THE INDENTURE REFERRED TO ON THE REVERSE HEREOF.

(ii) The Company, acting in its discretion, may remove the Restricted Legend from any Transfer Restricted Note at any time on or after the Resale Restriction Termination Date applicable to such Transfer Restricted Note. Without limiting the generality of the preceding sentence, the Company may effect such removal by issuing and delivering, in exchange for such Transfer Restricted Note, an Unrestricted Note without such Restricted Legend, registered to the same Holder and in an equal principal amount, and upon receipt by the Trustee of a Company Order stating that the Resale Restriction Termination Date applicable to such Transfer Restricted Note has occurred and requesting the authentication and delivery of an Unrestricted Note in exchange therefor given at least three Business Days in advance of the proposed date of exchange specified therein (which shall be no earlier than such Resale Restriction Termination Date), the Trustee shall authenticate and deliver such Unrestricted Note to the Depositary or pursuant to such Depositary’s instructions or hold such Note as Security Custodian and shall request the Depositary to, or, if the Trustee is custodian of such Transfer Restricted Note, shall itself, surrender such Transfer Restricted Note in exchange for such Unrestricted Note without such Restricted Legend and thereupon cancel such Transfer Restricted Note so surrendered, all as directed in such order. For purposes of determining whether the Resale Restriction Termination Date has occurred with respect to any Notes evidenced by a Transfer Restricted Note or delivering any order pursuant to this Section 2.3(c)(ii) with respect to such Notes, (i) only those Notes which a Principal Officer of the Company actually knows (after reasonable inquiry) to be or to have been owned by an Affiliate of the Company shall be deemed to be or to have been, respectively, owned by an Affiliate of the Company; and (ii) “Principal Officer” means the principal executive officer, the principal financial officer, the treasurer or the principal accounting officer of the Company.

For purposes of this Section 2.3(c)(ii), all provisions relating to the removal of the Restricted Legend shall relate, if the Resale Restriction Termination Date has occurred only with respect to a portion of the Notes evidenced by a Transfer Restricted Note, to such portion of the Notes so evidenced as to which the Resale Restriction Termination Date has occurred.

Each holder of any Notes evidenced by any Restricted Global Note, by its acceptance thereof, (A) authorizes and consents to, (B) appoints the Company as its agent for the sole purpose of delivering such electronic messages, executing and delivering such instruments and taking such other actions, on such holder’s behalf, as the Depositary or the Trustee may require to effect, and (C) upon the request of the Company, agrees to deliver such electronic messages, execute and deliver such instruments and take such other actions as the Depositary or the Trustee may require, or as shall otherwise be necessary to effect, the removal of the Restricted Legend (including by means of the exchange of all or the portion of such Restricted Global Note evidencing such Note for a certificate evidencing such Note that does not bear such legend) at any time after the Resale Restriction Termination Date.

Appendix-6

(iii) Upon any sale or transfer of a Transfer Restricted Note pursuant to Rule 144 under the Securities Act, the Registrar shall permit the transferee thereof to exchange such Transfer Restricted Note for a Note that does not bear the Restricted Legend and rescind any restriction on the transfer of such Transfer Restricted Note, if the transferor thereof certifies in writing to the Registrar that, and if the Company or the Trustee so request, delivers an opinion of counsel to the effect that, such sale or transfer was made in reliance on Rule 144 (such certification to be in the form set forth on the reverse of the Note).

(iv) After a transfer of any Transfer Restricted Notes pursuant to and during the period of the effectiveness of a Shelf Registration Statement with respect to such Notes, all requirements pertaining to the Restricted Legend on such Notes will cease to apply, and an Exchange Note in global form, without such legend, will be available to the transferee of the Holder of such Notes upon directions to transfer such Holder’s interest in the Global Security.

(v) Upon the consummation of a Registered Exchange Offer with respect to Transfer Restricted Notes, the Company shall issue Exchange Notes in global form to Holders that exchange such Transfer Restricted Notes in such Registered Exchange Offer.

(d) Restrictions on Transfer of Temporary Regulation S Global Notes. During the Restricted Period, beneficial ownership interests in Temporary Regulation S Global Notes may only be sold, pledged or transferred in accordance with the applicable procedures of the Depositary and only (i) to the Company, (ii) in an offshore transaction in accordance with Regulation S (other than a transaction resulting in an exchange for an interest in a Permanent Regulation S Global Note) or (iii) pursuant to an effective registration statement under the Securities Act, in each case, in accordance with any applicable securities laws of any state of the United States.

(e) No Obligation of the Trustee. The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under the Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among Depositary participants, members or beneficial owners in any Global Security) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the terms of the Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof.

2.4 Definitive Notes.

(a) A Global Security deposited with the Depositary or with the Trustee as custodian for the Depositary pursuant to Section 2.1 shall be transferred to the beneficial owners thereof in the form of Definitive Notes in an aggregate principal amount equal to the principal amount of such Global Security, in exchange for such Global Security, only in the circumstances described in Section 2.17 of the Base Indenture and only if such transfer complies with Section 2.3 hereof. Any Definitive Note delivered in exchange for an interest in a Global Security shall, except as otherwise provided by Section 2.3, bear the Restricted Legend.

Appendix-7

The Depository Trust Company (55 ▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇ ▇▇▇▇, ▇▇▇ ▇▇▇▇), a New York corporation (“DTC”), shall act as the Depositary until a successor shall be appointed by the Company and the Registrar. Unless this certificate is presented by an authorized representative of DTC to the issuer or its agent for registration of transfer, exchange or payment, and any certificate issued is registered in the name of Cede & Co. or in such other name as is requested by an authorized representative of DTC (and any payment is made to Cede & Co. or to such other entity as is requested by an authorized representative of DTC), ANY TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON IS WRONGFUL inasmuch as the registered owner hereof, Cede & Co., has an interest herein.]*

3.95% SENIOR NOTE DUE 2028

This Security is one of a duly authorized issue of 3.95% Senior Notes due 2028 (the “Securities”) of ▇▇▇▇▇▇▇▇▇-UTI Energy, Inc., a Delaware corporation (the “Company”).

1. Interest. The Company promises to pay interest on the principal amount of this Security at 3.95% per annum. The Company will pay interest semiannually on February 1 and August 1 of each year (each an “Interest Payment Date”), or if any such day is not a Business Day, on the next succeeding Business Day. Interest on the Securities will accrue from the most recent Interest Payment Date on which interest has been paid or, if no interest has been paid, from January 19, 2018; provided that if there is no existing Default in the payment of interest, and if this Security is authenticated between a record date referred to on the face hereof (each, a “Record Date”) and the next succeeding Interest Payment Date, interest shall accrue from such next succeeding Interest Payment Date; provided, further, that the first Interest Payment Date shall be August 1, 2018. The Company shall pay interest on overdue principal and premium (if any) from time to time at a rate equal to the interest rate then in effect; it shall pay interest on overdue installments of interest (without regard to any applicable grace periods) from time to time at the same rate to the extent lawful. Interest will be computed on the basis of a 360-day year consisting of twelve 30-day months.

2. Method of Payment. The Company will pay interest on the Securities (except defaulted interest) to the Persons who are registered Holders of Securities at the close of business on the Record Date next preceding the Interest Payment Date, even if such Securities are canceled after such Record Date and on or before such Interest Payment Date. The Holder must surrender this Security to a Paying Agent to collect principal payments. The Company will pay the principal of, premium (if any) on and interest on the Securities in money of the United States of America that at the time of payment is legal tender for payment of public and private debts. Such amounts shall be payable at the offices of the Trustee (as defined below). Payments in respect of Global Securities shall be made by wire transfer of immediately available funds to the accounts specified by the Holder thereof. In all other cases, at the option of the Company, payment of interest may be made at the Corporate Trust Office of the Trustee or by check mailed to the address of the person entitled thereto as such address shall appear in the register of the Notes maintained by the Registrar. Notwithstanding the foregoing, payments in respect of a Definitive Note in certificated form shall be made by wire transfer to a Dollar account maintained by the payee with a bank in the United States if the Holder of such Definitive Note elects payment by wire transfer by giving written notice to the Trustee or the Paying Agent to such effect in accordance with the Indenture (as defined below).

3. Paying Agent and Registrar. Initially, ▇▇▇▇▇ Fargo Bank, National Association (the “Trustee”), the trustee under the Indenture, will act as Paying Agent and Registrar. The Company may change any Paying Agent or Registrar without notice to any Holder. The Company, any Subsidiary Guarantor or any other Subsidiary of the Company may act in any such capacity.

A-7

4. Indenture. The Company issued the Securities under an Indenture, dated as of January 19, 2018 (the “Base Indenture”), among the Company, the Subsidiary Guarantors party thereto and the Trustee, as amended and supplemented with respect to the Securities by the First Supplemental Indenture thereto, dated as of January 19, 2018 and as it may otherwise be amended and supplemented thereafter with applicability to the Securities (the Base Indenture, as so amended and supplemented, the “Indenture”). The terms of the Securities include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (the “TIA”), as in effect on the date of execution of the Indenture. The Securities are subject to all such terms, and Holders are referred to the Indenture and the TIA for a statement of such terms and for the definitions of capitalized terms used but not defined herein. The Securities are unsecured general obligations of the Company limited to $525,000,000 in aggregate principal amount; provided, however, that the authorized aggregate principal amount of the Securities may be increased before or after the issuance of any Securities by a Board Resolution (or action pursuant to a Board Resolution) to such effect. The Base Indenture provides for the issuance of other series of debt securities (including the Securities, the “Debt Securities”) thereunder.

5. Guarantees. Each of the Subsidiary Guarantors named pursuant to the Indenture fully, unconditionally and absolutely guarantees to the Holders and to the Trustee the due and punctual payment of the principal of, and premium, if any, and interest on the Securities and all other amounts due and payable under the Indenture and the Securities by the Company, when and as such principal, premium, if any, and interest shall become due and payable, whether at the Stated Maturity or by declaration of acceleration, call for redemption or otherwise, according to the terms of the Securities and the Indenture, subject to the limitations set forth in the Indenture. In the event of a default in payment of the principal of, or premium, if any, or interest on the Securities, whether at the Stated Maturity or by declaration of acceleration, call for redemption or otherwise, legal proceedings may be instituted by the Trustee on behalf of the Holders or, subject to the Indenture, by the Holders, on the terms and conditions set forth in the Indenture, directly against any Subsidiary Guarantor to enforce its Guarantee without first proceeding against the Company or any other Subsidiary Guarantor.

6. Denominations, Transfer, Exchange. The Securities are in registered form without coupons in minimum denominations of $2,000 and any integral multiples of $1,000. The transfer of Securities may be registered and Securities may be exchanged as provided in the Indenture. The Registrar and the Trustee may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. Neither the Company, any Subsidiary Guarantor, the Trustee nor the Registrar shall be required to register the transfer or exchange of (a) any Security selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part, or (b) any Security during the period beginning 15 Business Days before the giving of notice of redemption of Securities to be redeemed or a notice of a Change of Control Offer and ending at the close of business on the day of transmission.

7. Persons Deemed Owners. The registered Holder of a Security shall be treated as its owner for all purposes.

A-8

8. Redemption. The Securities are subject to redemption, in whole at any time and in part from time to time, at the option of the Company, in principal amounts of $1,000 and integral multiples of $1,000 above such amount (provided that the unredeemed portion of any Security redeemed in part may not be less than $2,000), upon not less than 30 nor more than 60 days’ prior notice as provided in the Indenture, at a Redemption Price equal to (i) if the Redemption Date is prior to November 1, 2027, the greater of (1) 100% of the principal amount of the Securities to be redeemed and (2) the sum of the present values of the remaining scheduled payments of principal and interest thereon that would be due if the Securities matured on November 1, 2027 (exclusive of the interest accrued to the Redemption Date) computed by discounting such payments to the Redemption Date on a semi-annual basis, assuming a 360-day year consisting of twelve 30-day months, at a rate equal to the sum of the Adjusted Treasury Rate for such Securities plus 25 basis points; or (ii) if the Redemption Date is on or after November 1, 2027, 100% of the principal amount of the Securities to be redeemed, plus, in each of clauses (i) and (ii), 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).

9. Amendments and Waivers. Subject to certain exceptions and limitations, the Indenture or the Securities may be amended or supplemented with the consent of the Holders of a majority in principal amount of the then outstanding Debt Securities of all series affected by such amendment or supplement (acting as one class), and any existing or past Default or Event of Default under, or compliance with any provision of, the Indenture may be waived (other than any continuing Default or Event of Default in the payment of the principal of, premium (if any) on or interest on the Securities) by the Holders of a majority in principal amount of the then outstanding Debt Securities of any series or of all series (acting as one class) in accordance with the terms of the Indenture. Without the consent of any Holder, the Company, the Subsidiary Guarantors and the Trustee may amend or supplement the Indenture or the Securities or waive any provision of either: (i) to cure any ambiguity, omission, defect or inconsistency; (ii) if required, to provide for the assumption of the obligations of the Company under the Indenture in the case of the merger, consolidation, amalgamation or sale, conveyance, transfer or lease of assets of the Company substantially as an entirety; (iii) to provide for uncertificated Securities in addition to or in place of certificated Securities; (iv) to provide any security for, any guarantees of or additional obligors or guarantors on, the Securities or the related Guarantees or release any Subsidiary Guarantor from its Guarantee in the manner provided in the Indenture; (v) to comply with any requirement in order to effect or maintain the qualification of the Indenture under the TIA; (vi) to add to the covenants of the Company or any Subsidiary Guarantor for the benefit of the Holders of the Securities, or to surrender any right or power conferred by the Indenture upon the Company or any Subsidiary Guarantor; (vii) to add any additional Events of Default with respect to all or any series of the Debt Securities; (viii) to change or eliminate any of the provisions of the Indenture, provided that the Holders of outstanding Securities are not adversely affected in any material respect; (ix) to supplement any of the provisions of the Indenture to such extent as shall be necessary to permit or facilitate the defeasance and discharge of the Securities pursuant to the Indenture; or (x) to evidence and provide for the acceptance of appointment under the Indenture by a successor Trustee with respect to the Securities and to add to or change any of the provisions of the Indenture as shall be necessary to provide for or facilitate the administration of the trusts thereunder by more than one Trustee, pursuant to the requirements of the Indenture.

A-9

The right of any Holder to participate in any consent required or sought pursuant to any provision of the Indenture (and the obligation of the Company or any Subsidiary Guarantor to obtain any such consent otherwise required from such Holder) may be subject to the requirement that such Holder shall have been the Holder of record of any Securities with respect to which such consent is required or sought as of a date identified by the Company or such Subsidiary Guarantor in a notice furnished to Holders in accordance with the terms of the Indenture.

Without the consent of each Holder affected, an amendment, supplement or waiver may not (i) reduce the amount of Debt Securities whose Holders must consent to an amendment, supplement or waiver; (ii) reduce the rate of or change the time for payment of interest, including default interest, on any Security; (iii) reduce the principal of or premium on, or change the Stated Maturity of, any Security; (iv) reduce the premium, if any, payable upon the redemption of any Security or change the time at which any Security may or shall be redeemed; (v) change the coin or currency in which any Security or any premium or interest with respect thereto is payable; (vi) impair the right to institute suit for the enforcement of any payment of principal of or premium (if any) or interest on any Security, except as provided in the Indenture; (vii) make any change in the percentage of principal amount of Debt Securities necessary to waive compliance with certain provisions of the Indenture or make any change in the provision for modification; or (viii) waive a continuing Default or Event of Default in the payment of principal of or premium (if any) or interest on the Securities.

A supplemental indenture that changes or eliminates any covenant or other provision of the Base Indenture, as supplemented from time to time, which has expressly been included solely for the benefit of one or more particular series of Debt Securities under the Base Indenture, or which modifies the rights of the Holders of Debt Securities of such series with respect to such covenant or other provision, shall be deemed not to affect the rights under the Indenture of the Holders of Debt Securities of any other series.

10. Defaults and Remedies. Events of Default are defined in the Indenture and generally include: (i) default for 30 days in payment of any interest on the Securities; (ii) default in any payment of principal of or premium, if any, on the Securities as and when due and payable; (iii) default by the Company or any Subsidiary Guarantor in compliance with any of its other covenants or agreements in, or provisions of, the Securities or in the Indenture which shall not have been remedied within 60 days after written notice by the Trustee or by the holders of at least 25% in principal amount of the Securities then outstanding (or, in the event that other Debt Securities issued under the Base Indenture are also affected by the default, then 25% in principal amount of all outstanding Debt Securities so affected); (iv) certain events involving bankruptcy, insolvency or reorganization of the Company, any Subsidiary Guarantor that is a Significant Subsidiary or any group of Subsidiary Guarantors that, considered in the aggregate as a single Subsidiary, would constitute a Significant Subsidiary or (v) any Guarantee by a Subsidiary Guarantor that is a Significant Subsidiary or any group of Subsidiary Guarantors that, considered in the aggregate as a single Subsidiary, would constitute a Significant Subsidiary ceases to be in full force and effect with respect to Securities (except as otherwise provided in the Indenture). If an Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the then outstanding Securities (or, in the case of an Event of Default described in clause (iii) above, if outstanding Debt Securities of other series are affected by such

A-10

Default, then at least 25% in principal amount of the then outstanding Debt Securities so affected), may declare the principal of and interest on all the Securities (or such Debt Securities) to be immediately due and payable, except that in the case of an Event of Default described in clause (iv) above, all outstanding Debt Securities under the Base Indenture become due and payable immediately without further action or notice. The amount due and payable upon the acceleration of any Security is equal to 100% of the principal amount thereof plus accrued interest to the date of payment. Holders may not enforce the Indenture or the Securities except as provided in the Indenture. The Trustee may require security or indemnity satisfactory to it before it enforces the Indenture or the Securities. Subject to certain limitations, Holders of a majority in principal amount of the then outstanding Securities (or affected Debt Securities) may direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders notice of any continuing default (except a default in payment of principal, premium or interest) if it determines that withholding notice is in their interests. The Company must furnish annual compliance certificates to the Trustee.

11. Discharge Prior to Maturity. The Indenture with respect to the Securities shall be discharged and canceled upon the payment of all of the Securities and shall be discharged except for certain obligations upon the irrevocable deposit with the Trustee of any combination of funds and Government Obligations sufficient for such payment.

12. Trustee Dealings with Company or Subsidiary Guarantors. The Trustee, in its individual or any other capacity, may become the owner or pledgee of Securities and may make loans to, accept deposits from, and perform services for the Company, any Subsidiary Guarantor or any of their respective Affiliates, and may otherwise deal with the Company, any Subsidiary Guarantor or any such Affiliates, as if it were not Trustee.

13. No Recourse Against Others. The Trustee, and each Holder of a Security by its acceptance hereof, will be deemed to have agreed in the Indenture that no director, manager, member, officer, employee, stockholder, partner, unitholder or other owner of the Company, any Subsidiary Guarantor, the Trustee or any Affiliate of the foregoing entities shall have any liability in respect of the obligations of the Company, a Subsidiary Guarantor and the Trustee under the Indenture, the Securities or any related Guarantees by reason of his, her or its status. Each Holder by accepting a Security waives and releases all such liability. The waiver and release shall be part of the consideration for the issuance of Securities.

14. Authentication. This Security shall not be valid until authenticated by the manual signature of the Trustee or an authenticating agent.

15. 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 Securities as a convenience to the Holders of the Securities. No representation is made as to the accuracy of such numbers as printed on the Securities and reliance may be placed only on the other identification numbers printed thereon.

16. 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).
