The following defined terms used solely for purposes of this Section 1.04 shall, unless the context otherwise requires, have the meanings specified below for purposes of the Notes.

"Treasury Rate" means the rate per year, calculated on the third Business Day preceding the Redemption Date, equal to (i) 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 that establishes yields on actively traded United States Treasury securities adjusted to constant maturity under the caption "Treasury Constant Maturities," for the maturity corresponding to the Comparable Treasury Issue; provided that if no

maturity is within three months before or after the Par Call Date for the applicable series of Notes being redeemed, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue will be determined and the Treasury Rate will be interpolated or extrapolated from those yields on a straight line basis rounding to the nearest month; or (ii) if that release, or any successor release, is not published during the week preceding the calculation date or does not contain such yields, the rate per year equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for that Redemption Date.

"Comparable Treasury Issue" means the United States Treasury security selected by an Independent Investment Banker that would be used, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the Par Call Date of the applicable series of Notes.

"Comparable Treasury Price" means (i) the average of the Reference Treasury Dealer Quotations for that Redemption Date, after excluding the highest and lowest of the Reference Treasury Dealer Quotations, or (ii) if the Company obtains fewer than three Reference Treasury Dealer Quotations, the average of all Reference Treasury Dealer Quotations so received.

"Independent Investment Banker" means one of the Reference Treasury Dealers that the Company appoints.

"Par Call Date" means the 2020 Notes Par Call Date in the case of the 2020 Notes, the 2022 Notes Par Call Date in the case of the 2022 Notes, the 2025 Notes Par Call Date in the case of the 2025 Notes, the 2035 Notes Par Call Date in the case of the 2035 Notes and the 2045 Notes Par Call Date in the case of the 2045 Notes.

"Reference Treasury Dealer" means each of Citigroup Global Markets Inc. (and its successors), Credit Suisse Securities (USA) LLC (and its successors), Xxxxxxx Lynch, Pierce, Xxxxxx & Xxxxx Incorporated (and its successors), Mizuho Securities USA Inc. (and its successors) and any other nationally recognized investment banking firm that is a primary U.S. Government securities dealer specified from time to time by the Company. If, however, any of them shall cease to be a primary U.S. Government securities dealer in New York City, the Company will substitute another nationally recognized investment banking firm that is such a dealer.

"Reference Treasury Dealer Quotations" means, with respect to each Reference Treasury Dealer and any Redemption Date, the average, as determined by the Company, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Company by such Reference Treasury Dealer as of 3:30 p.m., New York time, on the third Business Day preceding the Redemption Date.

"Remaining Scheduled Payments" means the remaining scheduled payments of the principal of and interest on each Note of the series to be redeemed that would be due after the related Redemption Date but for such redemption if such series of Notes matured on the applicable Par Call Date. If the Redemption Date is not an Interest Payment Date with respect to the Note of the series being redeemed, the amount of the next succeeding scheduled interest payment on the

Note of the series being redeemed will be reduced by the amount of interest accrued thereon to that Redemption Date.

SECTION 1.05 Special Mandatory Redemption.

The Company has entered into an Agreement and Plan of Merger, dated as of November 16, 2014 (as it may be amended, restated or supplemented from time to time, the "Merger Agreement"), among the Company, Red Tiger LLC and Xxxxx Xxxxxx Incorporated to acquire all of the outstanding shares of Xxxxx Xxxxxx Incorporated (the "Xxxxx Xxxxxx acquisition").

If the Xxxxx Xxxxxx acquisition is not completed on or prior to November 13, 2016, or if, prior to such date, the Merger Agreement is terminated for any reason (each, a "Special Mandatory Redemption Event"), the 2020 Notes and the 2022 Notes (collectively, the "Redeemable Notes") will be redeemed in whole at a special mandatory redemption price (the "Special Mandatory Redemption Price") equal to 101% of the aggregate principal amount of the applicable series of Redeemable Notes being redeemed, plus, in each case, accrued but unpaid interest on the principal amount of such series of Redeemable Notes to, but not including, the Special Mandatory Redemption Date (as defined below).

Upon the occurrence of a Special Mandatory Redemption Event, the Company shall promptly (but in no event later than 5 Business Days following such Special Mandatory Redemption Event) notify the Trustee in writing of such event, and shall, no later than 5 Business Days following such notice to the Trustee, mail (or with respect to Global Securities, to the extent permitted or required by applicable procedures or regulations of the Depositary, send electronically) a notice of redemption to the registered address of each Holder of the Redeemable Notes (such date of notification to the Holders, the "Redemption Notice Date") fixing the date of such special mandatory redemption, which date shall not be later than the 30th day following the Redemption Notice Date (such date, the "Special Mandatory Redemption Date"), in accordance with Section 10.02 of the Original Indenture. The Company shall notify each Holder of the Redeemable Notes in accordance with Section 10.02 of the Original Indenture that all of the outstanding Redeemable Notes shall be redeemed at the Special Mandatory Redemption Price on the Special Mandatory Redemption Date automatically and without any further action by the Holders of any series of Redeemable Notes. At or prior to 12:00 p.m. (New York City time) on the Business Day immediately preceding the Special Mandatory Redemption Date, the Company shall deposit with the Trustee funds sufficient to pay the Special Mandatory Redemption Price for each series of Redeemable Notes. If such deposit is made as provided above, all of the Redeemable Notes will cease to bear interest on and after the Special Mandatory Redemption Date.

The 2025 Notes, the 2035 Notes and the 2045 Notes shall not be subject to this Section 1.05.

Upon the closing of the Xxxxx Xxxxxx acquisition, the provisions of this Section 1.05 regarding the special mandatory redemption will cease to apply.

SECTION 1.06 Denominations.

The Notes shall be issued only in fully registered book-entry form, without coupons, in denominations of $2,000 and integral multiples of $1,000 in excess thereof.

2.700% SENIOR NOTES DUE 2020

This Security is one of a duly authorized issue of 2.700% Senior Notes Due 2020 (the "Securities") of Halliburton Company, a Delaware corporation (the "Issuer"). The Issuer issued the Securities under an Indenture dated as of October 17, 2003 (the "Original Indenture") between the Issuer and The Bank of New York Mellon Trust Company, N.A. (as successor to JPMorgan Chase Bank), as trustee (the "Trustee"), as supplemented by the Eighth Supplemental Indenture dated as of November 13, 2015 (the "Eighth Supplemental Indenture" and, together with the Original Indenture, the "Indenture"). Capitalized terms used herein for which no definition is provided herein shall have the meanings set forth in the Indenture.

1. Interest. The Issuer promises to pay interest on the principal amount of this Security at 2.700% per annum from November 13, 2015 until maturity. The Issuer will pay interest semiannually on May 15 and November 15 of each year, 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 November 13, 2015; 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 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 May 15, 2016. Interest will be computed on the basis of a 360-day year of twelve 30-day months.

2. Method of Payment. The Issuer 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 Issuer will pay the principal of 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 or any Paying Agent, provided that at the option of the Issuer, the Issuer may pay such amounts (1) by wire transfer with respect to Securities represented by a Global Note or (2) by check payable in such money mailed to a Holder's registered address with respect to any Security.

3. Paying Agent and Registrar. Initially, the Trustee will act as Paying Agent and Registrar. The Issuer may change any Paying Agent, Registrar, co-registrar or additional paying agent without notice to any Holder. The Issuer or any of the Issuer's subsidiaries may act in any such capacity.

4. Indenture. The terms of the Securities include those stated in the Indenture and the provisions made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (15 U.S. Code §§ 77aaa-77bbbb) (the "TIA"), as in effect on the date of the Eighth Supplemental Indenture; provided, that if any provision of the Indenture limits, qualifies or conflicts with the duties imposed by operation of TIA Section 318(c), the imposed duties shall control. Holders are

A-5

referred to the Indenture and the TIA for a statement of such terms and provisions. The Securities are unsecured senior obligations of the Issuer and rank equally with all of the Issuer's existing and future unsecured indebtedness. The Indenture provides for the issuance of other series of debt securities thereunder.

5. Denominations, Transfer, Exchange. The Securities are in registered form without coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof. 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. The Registrar need not exchange or register the transfer of any Securities during the period between a record date and the corresponding Interest Payment Date.

6. Optional Redemption. No sinking fund is provided for the Securities. At any time and from time to time before October 15, 2020, the Securities will be redeemable, in the Issuer's sole discretion, in whole or in part, in principal amounts of $2,000 or any integral multiple of $1,000 in excess thereof for an amount equal to the greater of:

(i) 100% of the principal amount of the Securities being redeemed; and

(ii) as determined by an Independent Investment Banker, the sum of the present values of the Remaining Scheduled Payments on the Securities, discounted to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 20 basis points.

At any time and from time to time on or after October 15, 2020, the Securities will be redeemable, in the Issuer's sole discretion, in whole or in part, in principal amounts of $2,000 or any integral multiple of $1,000 in excess thereof for an amount equal to 100% of the principal amount of the Securities being redeemed.

In the event of any such redemption, interest will accrue up to the date of redemption. Unless there is a default in payment of the redemption amount, on and after the Redemption Date, interest will cease to accrue on the Securities or portions thereof called for redemption.

7. Special Mandatory Redemption. The Issuer has entered into an Agreement and Plan of Merger, dated as of November 16, 2014 (as it may be amended, restated or supplemented from time to time, the "Merger Agreement"), among the Issuer, Red Tiger LLC and Xxxxx Xxxxxx Incorporated to acquire all of the outstanding shares of Xxxxx Xxxxxx Incorporated (the "Xxxxx Xxxxxx acquisition").

If the Xxxxx Xxxxxx acquisition is not completed on or prior to November 13, 2016, or if, prior to such date, the Merger Agreement is terminated for any reason (each, a "Special Mandatory Redemption Event"), the Securities will be redeemed in whole at a special mandatory redemption price (the "Special Mandatory Redemption Price") equal to 101% of the aggregate principal amount of the Securities being redeemed, plus accrued but unpaid interest on the principal amount of such Securities to, but not including, the Special Mandatory Redemption Date (as defined below).

A-6

Upon the occurrence of a Special Mandatory Redemption Event, the Issuer shall promptly (but in no event later than 5 Business Days following such Special Mandatory Redemption Event) notify the Trustee in writing of such event, and shall, no later than 5 Business Days following such notice to the Trustee, mail (or with respect to Global Securities, to the extent permitted or required by applicable procedures or regulations of the Depositary, send electronically) a notice of redemption to the registered address of each Holder of the Securities (such date of notification to the Holders, the "Redemption Notice Date") fixing the date of such special mandatory redemption, which date shall not be later than the 30th day following the Redemption Notice Date (such date, the "Special Mandatory Redemption Date"), in accordance with Section 10.02 of the Original Indenture. The Issuer shall notify each Holder of the Securities in accordance with Section 10.02 of the Original Indenture that all of the outstanding Securities shall be redeemed at the Special Mandatory Redemption Price on the Special Mandatory Redemption Date automatically and without any further action by the Holders of any of the Securities. At or prior to 12:00 p.m. (New York City time) on the Business Day immediately preceding the Special Mandatory Redemption Date, the Issuer shall deposit with the Trustee funds sufficient to pay the Special Mandatory Redemption Price for the Securities. If such deposit is made as provided above, all of the Securities will cease to bear interest on and after the Special Mandatory Redemption Date.

Upon the closing of the Xxxxx Xxxxxx acquisition, the provisions regarding the special mandatory redemption will cease to apply.

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

9. Amendments and Waivers. Subject to certain exceptions and limitations, the Indenture or the Securities may be amended or supplemented by the Issuer and the Trustee with the written consent (including consents obtained in connection with a tender offer or exchange offer or a solicitation of consents, provided that in each case such offer or solicitation is made to all Holders of then outstanding Securities) of the Holders of at least a majority in principal amount of the then outstanding Securities affected by such amendment or supplement (provided that if such amendment or supplement affects holders of securities of other series issued under the Original Indenture, the Holders of the Securities and such other series of securities shall act 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) or interest on the Securities or a continued Default in respect of a provision that cannot be amended or supplemented without the consent of each Holder of the Securities affected) by the Holders of at least a majority in principal amount of the then outstanding Securities (or of all series of securities issued under the Original Indenture acting as one class in the case of a Default or Event of Default with respect to all such series, as the case may be) in accordance with the terms of the Indenture. The Issuer and the Trustee may amend or supplement the Indenture or the Securities or waive any provision of either without the consent of the Holders, to:

(9) 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 Section 8.01 of the Original Indenture, provided, however, that any such action shall not adversely affect the interest of the Holders of the Securities or the holders of any other series of securities issued under the Original Indenture in any material respect;

(10) evidence and provide for the acceptance of appointment hereunder 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 Section 7.08 of the Original Indenture; or

(11) make any other change that does not adversely affect the rights of any Holder of Securities.

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 Issuer 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 Securities with respect to which such consent is required or sought as of a date fixed in accordance with the terms of the Indenture.

Without the consent of each Holder affected, the Issuer may not:

(1) reduce the amount of securities issued under the Original Indenture (including the Securities) whose Holders must consent to an amendment, supplement or waiver;

(7) make any change in the percentage of principal amount of Securities necessary to waive compliance with certain provisions of the Indenture pursuant to Section 6.04 or 6.07 of the Original Indenture or make any change in the fifth paragraph of Section 9.02 of the Original Indenture; or

(8) waive a continuing Default or Event of Default in the payment of principal of, premium (if any) or interest on the Securities.

A supplemental indenture that changes or eliminates any covenant or other provision of the Indenture which has expressly been included solely for the benefit of one or more particular series of securities issued under the Original Indenture (including the Securities), or which modifies the rights of the holders of securities of such series of securities issued under the Original Indenture (including the Securities) with respect to such covenant or other provision, shall be deemed not to affect the rights under the Indenture of the holders of the securities of any other series.

(3) default by the Issuer in its compliance with any of its other covenants or agreements in, or provisions of, the Securities or the Indenture which shall not have been remedied within 60 days after written notice to the Issuer by the Trustee or to the Issuer and Trustee by the holders of at least 25% in aggregate principal amount of the securities of all series of securities issued under the Original Indenture (including the Securities) then outstanding affected by such default;

A-9

on which it would otherwise have become due and payable and such payment default is not cured or such acceleration is not rescinded within 30 days after notice to the Issuer in accordance with the terms of the Indebtedness; and

(5) certain events involving bankruptcy, insolvency or reorganization affecting the Issuer.

The Trustee shall not be deemed to know or have notice of any Default or Event of Default unless a Trust Officer at the Corporate Trust Office of the Trustee receives written notice at the Corporate Trust Office of the Trustee of such Default or Event of Default with specific reference to such Default or Event of Default.

If an Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of the outstanding Securities affected by such Event of Default (or, in the case of an Event of Default described in clause (3) above, if outstanding securities of other series of securities issued under the Original Indenture are affected by such Event of Default, then at least 25% in principal amount of the then outstanding securities of all series (including the Securities) so affected), may declare the principal of and accrued and unpaid interest on all then outstanding Securities or securities of all such series, as the case may be, to be immediately due and payable, except that in the case of an Event of Default arising from certain events of bankruptcy, insolvency or reorganization affecting the Issuer, all outstanding Securities become due and payable immediately without further action or notice by the Trustee or any Holder. The amount due and payable upon the acceleration of any Security is equal to 100% of the principal amount thereof plus accrued and unpaid 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 indemnity satisfactory to it before it enforces the Indenture or the Securities. Subject to certain limitations, Holders of a majority in aggregate principal amount of the then outstanding Securities may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or may direct the Trustee in its exercise of any trust or power conferred on the Trustee. The Trustee may withhold from Holders notice of any continuing default (except a default in payment of principal, premium (if any) or interest) if it determines that withholding notice is in their interests. The Issuer must furnish an annual compliance certificate 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 issued thereunder and shall be discharged under certain circumstances specified in the Indenture upon the irrevocable deposit with the Trustee of funds or Government Obligations sufficient for such payment and the satisfaction of certain other conditions specified in the Indenture.

12. Defeasance. Subject to certain exceptions and conditions specified in the Indenture, the Issuer at any time may terminate some or all of its obligations under the Securities and the Indenture upon the irrevocable deposit with the Trustee of funds or Government Obligations sufficient for the payment of all the Securities on the dates those payments are due and payable.

13. Trustee Dealings with the Issuer. The Trustee, in its individual or any other capacity, may make loans to, accept deposits from, and perform services for the Issuer or its Affiliates, and may otherwise deal with the Issuer or its Affiliates, as if it were not Trustee.

A-10

14. No Recourse Against Others. A director, officer, employee or stockholder, as such, of the Issuer shall not have any liability for any obligations of the Issuer under the Securities or the Indenture or for any claim based on, in respect of or by reason of such obligations or their creation. Each Holder by accepting a Security waives and releases all such liability. The waiver and release are part of the consideration for the issuance of the Securities.

15. Authentication. The Securities shall not be valid until authenticated by the manual signature of the Trustee or an authenticating agent.

16. CUSIP Numbers. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Issuer 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.

17. Indenture to Control; Governing Law. In the case of any conflict between the provisions of this Security and the Indenture, the provisions of the Indenture shall control. The Indenture and the Securities shall be governed by and construed in accordance with the laws of the State of New York.

18. Successor Person. When a Successor assumes all the obligations of its predecessor under the Securities and the Indenture in accordance with the terms and conditions of the Indenture, the predecessor person will (except in certain circumstances specified in the Indenture) be released from those obligations.

19. Abbreviations and Definitions.
