 SECTION 2.01. The Form and Title of the Securities. 
 There is hereby
established two new series of Securities to be issued under the Indenture and to be designated as the Company’s 4.50% Senior Notes due 2022 (the “2022 Notes”) and the Company’s 5.95% Senior Notes due 2042 (the
“2042 Notes” and, together with the 2022 Notes, the “Notes”). The Notes shall be substantially in the forms attached as Exhibits A-1 and A-2 hereto, in each case, with such appropriate insertions,
omissions, substitutions and other variations as are required or permitted by the Indenture, and may have such letters, numbers or other marks of identification and such legends or endorsements placed thereon as the Company may deem appropriate or
as may be required or appropriate to comply with any applicable laws or with any rules made pursuant thereto or with the rules of any securities exchange or automated quotation system on which the Notes may be listed or traded, or to conform to
general usage, or as may, consistently with the Indenture, be determined by the officers executing such Notes, as evidenced by their execution thereof. 
 The Notes shall be executed, authenticated and delivered in accordance with the provisions of, and shall in all respects be subject to, the terms, conditions and covenants of the Original Indenture as
supplemented and amended by the Third Supplemental Indenture and this Fifth Supplemental Indenture (including the forms of Notes set forth as Exhibits A-1 and A-2 hereto (the terms of which are incorporated in and made a part of
this Fifth Supplemental Indenture for all intents and purposes)). 
 SECTION 2.02. Amount. 

The aggregate principal amount of the Notes which may be authenticated and delivered pursuant hereto is unlimited. The Trustee shall
initially authenticate and deliver Notes for original issue in initial aggregate principal amounts of up to $750,000,000 of the 2022 Notes and up to $550,000,000 of the 2042 Notes upon delivery to the Trustee of a Company Order for the
authentication and delivery of such Notes. The Company may, from time to time, without notice to or the consent of the Holders of the Notes, increase the principal amount of the Notes under the Indenture and issue such increased principal amount (or
any portion thereof), in which case any additional Notes so issued will have the same form and terms (other than the date of issuance and, under certain circumstances, the date from which interest thereon will begin to accrue), and will carry the
same right to receive accrued and unpaid interest, as the Notes previously issued, and such additional Notes will form a single series with the Notes previously issued. 
 SECTION 2.03. Stated Maturity and Denominations. 
 The Stated
Maturity of the 2022 Notes shall be April 15, 2022 and the Stated Maturity of the 2042 Notes shall be April 15, 2042. The Notes are issuable only in registered form without coupons in denominations of U.S. $2,000 and any integral multiple
of $1,000 in excess thereof. 
 SECTION 2.04. Interest and Interest Rates. 

The rate or rates at which the Notes shall bear interest, the date or dates from which such interest shall accrue, the Interest Payment
Dates on which any such interest shall be payable and the Regular Record Date for any interest payable on any Interest Payment Date, in each case, shall be as set forth in the form of applicable Note set forth as Exhibit A-1 or
Exhibit A-2 hereto. 
 SECTION 2.05. Place of Payment. 

As long as any Notes are outstanding, the Company shall maintain an office or agency in the Borough of Manhattan, The City of New York,
where Notes may be presented for payment. 
 SECTION 2.06. Optional Redemption. 

At its option, the Company may redeem either series of the Notes, in whole or in part, in principal amounts of $2,000 or an integral
multiple of $1,000 in excess thereof at the applicable times and at the applicable redemption prices determined as set forth in the form of applicable Note attached hereto as Exhibit A-1 and Exhibit A-2, in accordance with
the terms set forth in the Note and in accordance with Article Eleven of the Original Indenture.

 SECTION 2.07. Unconditional Guarantees. 

Article Fourteen of the Original Indenture (as amended and supplemented by the Third Supplemental Indenture and this Fifth
Supplemental Indenture) shall be applicable to the Notes and, accordingly, as more fully set forth in such Article Fourteen, the Guarantors, jointly and severally, fully, irrevocably, unconditionally and absolutely guarantee to the Holders of
Notes and to the Trustee the due and punctual payment of the principal of, and premium, if any, and interest on the Notes, and all other Indenture Obligations, when and as the same shall become due and payable, whether at the Stated Maturity, upon
redemption or by declaration of acceleration or otherwise. 
 To further evidence the Guarantees of the Notes, the Guarantors
hereby agree that a notation of such Guarantees in substantially in the form attached as Exhibit B hereto, in each case, with such appropriate insertions, omissions, substitutions and other variations as are required or permitted by the
Indenture, shall be endorsed on each Note authenticated and delivered by the Trustee and executed by either manual or facsimile signature of an officer of each of the Guarantors. Each Guarantor hereby agrees that its Guarantee of the Notes shall
remain in full force and effect notwithstanding any failure to endorse on any such Note a notation relating to the Guarantee thereof. 
 SECTION 2.08. Acceleration of Maturity; Rescission and Annulment. 

If an Event of Default with respect to the Notes at the time Outstanding occurs and is continuing, then in every such case the Trustee or
the Holders of 25% in aggregate principal amount of the Outstanding Securities of that series may declare the principal amount (or, if the Securities of that series are Original Issue Discount Securities, such portion of the principal amount as may
be specified in the terms of that series) of all of the Securities of that series to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by Holders), and upon any such declaration such principal amount
(or specified amount) shall become immediately due and payable. Notwithstanding the foregoing, if an Event of Default specified in clause (4) or (5) of Section 5.1 of the Indenture occurs, the Notes at the time Outstanding shall be
due and payable immediately without further action or notice. 
 ARTICLE 3 

OTHER AMENDMENTS TO INDENTURE 

SECTION 3.01. Amendments to Indenture 
 The amendments contained in this Section 3.01 shall apply to the Notes only and not to any other series of Securities issued under the Indenture. Such amendments shall be effective only for so long
as there remain outstanding any Notes. The Indenture is hereby amended, subject to the preamble of this Section 3.01 and with respect to the Notes only, by amending and restating Sections 10.5 and 10.6 thereof in their entirety as follows and
by adding the following as new Sections 10.10 and 10.11 thereof: 
 Section 10.5. Limitation on Liens. 

Weatherford Switzerland will not, nor will it permit any Subsidiary to, create, assume, incur or suffer to exist any Lien upon any
property, whether owned or leased on the date of this Fifth Supplemental Indenture or thereafter acquired, to secure any Debt of Weatherford Switzerland or any other Person (other than the Securities issued hereunder), without in any such case
making effective provision whereby all of the Securities Outstanding hereunder shall be secured equally and ratably with, or prior to, such Debt so long as such Debt shall be so secured. This restriction shall not apply to: 

(1) Liens (i) existing on the date any Securities are issued under this Indenture or (ii) provided for under the
terms of agreements existing on such date securing indebtedness existing on such date; 
 (2) Liens on current
assets to secure current liabilities; 

  
 3 







 (3) Liens on property acquired, constructed, altered or improved by
Weatherford Switzerland or any Subsidiary of Weatherford Switzerland after the date of this Indenture which are created or assumed contemporaneously with, or within one year after, such acquisition (or in the case of property constructed, altered or
improved, after the completion and commencement of commercial operation of such property, whichever is later) to secure or provide for the payment of any part of the purchase price of such property or the cost of such construction, alteration or
improvement, it being understood that if a commitment for such a financing is obtained prior to or within such one year period, the applicable Lien shall be deemed to be included in this clause (3) whether or not such Lien is created within
such one year period; provided that in the case of any such construction, alteration or improvement the Lien shall not apply to any property theretofore owned by Weatherford Switzerland or any Subsidiary of Weatherford Switzerland, other than
(i) the property so altered or improved and (ii) any theretofore unimproved real property on which the property so constructed or altered, or the improvement, is located; 

(4) Liens on any property existing at the time of acquisition thereof (including Liens on any property acquired from or
held by a Person which is consolidated or amalgamated with or merged with or into Weatherford Switzerland or a Subsidiary of Weatherford Switzerland) and Liens outstanding at the time any Person becomes a Subsidiary of Weatherford Switzerland that
are not incurred in connection with such entity becoming a Subsidiary of Weatherford Switzerland; 
 (5) Liens in
favor of Weatherford Switzerland or any Subsidiary of Weatherford Switzerland; 
 (6) Liens on any property
(i) in favor of the United States, any State thereof, any foreign country or any department, agency, instrumentality or political subdivision of any such jurisdiction, to secure partial, progress, advance or other payments pursuant to any
contract or statute, (ii) securing any indebtedness incurred for the purpose of financing all or any part of the purchase price or the cost of constructing, installing or improving the property subject to such Liens, including, without
limitation, Liens to secure Debt of the pollution control or industrial revenue bond type, or (iii) securing indebtedness issued or guaranteed by the United States, any State thereof, any foreign country, or any department, agency,
instrumentality or political subdivision of any such jurisdiction; 
 (7) Permitted Liens; and 

(8) any extension, renewal, or replacement (or successive extensions, renewals or replacements), in whole or in part, of
any Lien referred to in any of the foregoing clauses (1), (2), (3), (4), (5), (6) and (7) to the extent such extension, renewal or replacement (or successive extensions, renewals or replacements) involves a Lien described in the foregoing
clauses; provided, however, that the principal amount of Debt secured thereby shall not exceed the principal amount of Debt so secured at the time of such extension, renewal or replacement, together with the reasonable costs related to such
extension, renewal or replacement, and that such extension, renewal or replacement shall be limited to all or a part of the property which secured the Lien so extended, renewed or replaced (plus improvements on such property). 

Notwithstanding the foregoing provisions of this Section 10.5, Weatherford Switzerland and any Subsidiary of Weatherford Switzerland may issue,
assume or guarantee secured Debt, which would otherwise be subject to the foregoing restrictions, in an aggregate amount which, together with all other such secured Debt and together with the aggregate amount of Attributable Indebtedness of
Weatherford Switzerland and its Subsidiaries deemed to be outstanding in respect of all Sale-Leaseback Transactions (excluding any such Sale-Leaseback Transactions the proceeds of which have been applied in accordance with clauses (a), (b) or
(c) of Section 10.6) does not exceed 15% of Consolidated Net Worth, as shown on a consolidated balance sheet, as of a date not more than 150 days prior to the proposed transaction, prepared by Weatherford Switzerland in accordance with
generally accepted accounting principles. 
 For purposes of this Section 10.5 and for Section 10.6 only, “Subsidiary” means
(i) a corporation more than 50% of the outstanding voting stock of which is owned, directly or indirectly, by Weatherford Switzerland or by one or more other Subsidiaries of Weatherford Switzerland, or by Weatherford Switzerland and one or more
other Subsidiaries of Weatherford Switzerland or (ii) any partnership or similar business organization more than 50% of the ownership interests having ordinary voting power of which shall at the time be so owned. For the purposes of this
definition, “voting stock” means capital stock or equity interests which ordinarily have voting power for the election of directors, whether at all times or only so long as no senior class of stock has such voting power by reason of any
contingency.

Transaction with any Person (other than Weatherford Switzerland or a Subsidiary of Weatherford Switzerland) unless: 
 (a) at the time of entering into such Sale-Leaseback Transaction, Weatherford Switzerland or such Subsidiary of Weatherford Switzerland would be entitled to incur Debt, in a principal amount equal to the
Attributable Indebtedness with respect to such Sale-Leaseback Transaction, secured by a Lien on the property subject to such Sale-Leaseback Transaction, pursuant to Section 10.5 without equally and ratably securing the Securities pursuant to
such Section; 
 (b) after the Issue Date and within a period commencing six months prior to the consummation of
such Sale-Leaseback Transaction and ending six months after the consummation thereof, Weatherford Switzerland or such Subsidiary of Weatherford Switzerland shall have expended for property used or to be used in the ordinary course of business of
Weatherford Switzerland or such Subsidiary of Weatherford Switzerland (including amounts expended for additions, expansions, alterations, repairs and improvements thereto) an amount equal to all or a portion of the net proceeds of such
Sale-Leaseback Transaction, and Weatherford Switzerland shall have elected to designate such amount as a credit against such Sale-Leaseback Transaction (with any such amount not being so designated to be applied as set forth in clause

personal property leased in such Sale-Leaseback Transaction, which amount shall not be less than the fair value of such property at the time of entering into such Sale-Leaseback Transaction (adjusted to reflect the remaining term of the lease and
any amount expended by Weatherford Switzerland as set forth in clause (b) above), less an amount equal to the principal amount of Securities and pari passu indebtedness voluntarily defeased or retired by Weatherford Switzerland within such
12-month period and not designated as a credit against any other Sale-Leaseback Transaction entered into by Weatherford Switzerland or any Subsidiary of Weatherford Switzerland during such period. 

Section 10.10 Change of Control Repurchase at the Option of Holders 

(a) Upon the occurrence of a Change of Control Triggering Event, Holders of Securities will have the right to require the Company to make
an offer (the “Change of Control Offer”) to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of their Securities at a purchase price in cash equal to 101% of the aggregate principal amount of
Securities repurchased plus accrued and unpaid interest, if any, on the Securities repurchased, to the date of purchase (the “Change of Control Payment”). Within 30 days following any Change of Control Triggering Event, the Company

 (1) that the Change of Control Offer is being made pursuant to this Section 10.10 and that all Securities 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 mailed (the “Change of Control Payment Date”); 
 (3) that any Securities not tendered will continue to
accrue interest; 

  
 5 







 (4) that, unless the Company defaults in the payment of the Change of Control Payment, all
Securities 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 Securities repurchased pursuant to a Change of Control Offer will be required to surrender the Securities, with the form entitled “Option of Holder to Elect
Purchase” attached to the Securities completed, or transfer by book-entry transfer, to 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 receives, not later than the close of
business on the second Business Day preceding the Change of Control Payment Date, a telegram, telex, facsimile, transmission or letter setting forth the name of the Holder, the principal amount of Securities delivered for purchase, and a statement
that such Holder is withdrawing his election to have the Securities purchased; and 
 (7) that Holders whose Securities are
being purchased only in part will be issued new Securities equal in principal amount to the unpurchased portion of the Securities surrendered, which unpurchased portion must be equal to $2,000 in principal amount or in any 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 Securities as a result of a Change of Control Triggering Event. To the extent that the provisions of
any securities laws or regulations conflict with the provisions of this Section 10.10 (or compliance with this Section 10.10 would constitute a violation of any such laws or regulations), the Company will comply with the applicable
securities laws and regulations and will not be deemed to have breached its obligations under this Section 10.10 by virtue of such conflicts. 
 (b) On or before the Change of Control Payment Date, the Company will be required, to the extent lawful, to: 
 (1) accept for payment all Securities or portions of Securities properly tendered pursuant to the Change of Control Offer; 
 (2) deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Securities or portions of Securities properly tendered; and 

(3) deliver or cause to be delivered to the Trustee the Securities properly accepted. 

The Paying Agent will promptly (but in any case not later than five days after the Change of Control Payment Date) mail to each Holder of
Securities properly tendered the Change of Control Payment for such Securities, and the Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new Security equal in principal amount to any unpurchased
portion of the Securities surrendered, if any; provided that each new Security 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. 
 If Holders of not less than 95% in aggregate principal
amount of a series of outstanding Securities validly tender and do not withdraw such Securities in a Change of Control Offer and the Company, or any third party making a Change of Control Offer in lieu of the Company as described below, purchases
all of such Securities validly tendered and not withdrawn by such Holders, the Company will have the right, upon not less than 30 nor more than 60 days’ prior notice, given not more than 30 days following such purchase pursuant to the
Change of Control Offer described above, to redeem such Securities that remain outstanding following such purchase at a redemption price in cash equal to the applicable Change of Control Payment plus, to the extent not included in the Change of
Control Payment, accrued and unpaid interest, if any, to the date of redemption. 

  
 6 







 (c) Notwithstanding anything to the contrary in this Section 10.10, the Company will
not be required to make a Change of Control Offer with respect to a series of Securities upon a Change of Control Triggering Event 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 10.10 and purchases all Securities properly tendered and not withdrawn under the Change of Control Offer, or (2) notice of redemption has been given pursuant to Section 11.4 with respect

 [REVERSE OF NOTE] 
 WEATHERFORD INTERNATIONAL LTD. 
 a Bermuda exempted company 

4.50% Senior Notes due 2022 
 This Security is one of a duly authorized issue of senior securities of Weatherford International Ltd., a Bermuda exempted company (the “Company”) (herein called the
“Securities”), issued and to be issued in one or more series under an Indenture, dated as of October 1, 2003 (the “Original Indenture”) (the Original Indenture, as supplemented and amended by the Third
Supplemental Indenture thereto, dated as of February 26, 2009, and the Fifth Supplemental Indenture thereto, dated April 4, 2012, among the Company, Weatherford International Ltd., a Swiss joint-stock corporation (“Weatherford
Switzerland”), Weatherford International, Inc., a Delaware corporation (together with Weatherford Switzerland, the “Guarantors”), and Deutsche Bank Trust Company Americas, as Trustee (herein called the
“Trustee,” which term includes any successor trustee under the Original Indenture and any supplements and amendments thereto) being collectively referred to as the “Indenture”), to which Indenture and all indentures
supplemental thereto reference is hereby made for a statement, of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Guarantors, the Trustee and the Holders of the Securities and of the terms upon
which the Securities are, and are to be, authenticated and delivered. As provided in the Indenture, the Securities may be issued in one or more series, which different series may be issued in various aggregate principal amounts, may mature at
different times, may bear interest, if any, at different rates, may be subject to different redemption provisions, if any, may be subject to different sinking, purchase or analogous funds, if any, may be subject to different covenants and Events of
Default and may otherwise vary as in the Indenture provided or permitted. This Security is one of the series designated on the face hereof. 
 This Security is the general, unsecured, senior obligation of the Company and is guaranteed pursuant to guarantees (the “Guarantees”) by each of the Guarantors on a joint and several
basis. The Guarantees are the general, unsecured, senior obligation of the Guarantors. 
 Commencing on January 15, 2022
(90 days prior to the Stated Maturity), the Securities are subject to redemption upon not less than 30 nor more than 60 days’ notice by mail, at any time, as a whole or in part, at the election of the Company at a Redemption Price equal to
100% of the principal amount of Securities then outstanding to be redeemed, plus accrued and unpaid interest thereon to the redemption date. Prior to January 15, 2022 (90 days prior to the Stated Maturity), the Securities are subject to
redemption upon not less than 30 nor more than 60 days’ notice by mail, as a whole or in part, at the election of the Company at a Redemption Price equal to the greater of: (a) 100% of the principal amount of Securities then
outstanding to be redeemed, plus accrued and unpaid interest thereon to the redemption date; or (b) the sum of the present values of the remaining scheduled payments of principal and interest on the Securities then outstanding to be redeemed
(not including any portion of such payments of interest accrued as of the redemption date), discounted to the redemption date on a semi-annual basis (computed based on a 360-day year consisting of 12 30-day months) at the Adjusted Treasury Rate,
plus 35 basis points (0.35%), as calculated by an Independent Investment Banker, plus accrued and unpaid interest thereon to the redemption date; but interest installments whose Stated Maturity is on or prior to such Redemption Date will be payable
to the Holders of such Securities, or one or more Predecessor Securities, of record at the close of business on the relevant Record Dates referred to on the face hereof, all as provided in the Indenture. 

“Adjusted Treasury Rate” means, with respect to any redemption date: (a) the yield, under the heading which
represents the average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15(519)” or any successor publication which is published weekly by the Board of Governors of the Federal
Reserve System and which 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 (if no maturity is within three months before or after the remaining life, as defined below, yields for the two published maturities most closely corresponding to the 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 (b) 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 year equal to the semi-annual 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 such redemption date. The Adjusted Treasury Rate will be calculated on the third business day preceding the redemption date. 

  
 A-1-4








 “Comparable Treasury Issue” means the United States Treasury security
selected by an Independent Investment Banker as having a maturity comparable to the remaining term of the Securities to be redeemed 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 remaining term of such Securities. 
 “Comparable
Treasury Price” means (1) the average of five Reference Treasury Dealer Quotations for the redemption date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) if an Independent Investment Banker
obtains fewer than five such Reference Treasury Dealer Quotations, the average of all such quotations. 
 “Independent
Investment Banker” means J.P. Morgan Securities LLC, Morgan Stanley & Co. LLC, Citigroup Global Markets Inc. or Deutsche Bank Securities Inc. or any of their respective successors, as designated by the Company, or if all such firms
are unwilling or unable to serve as such, an independent investment and banking institution of national standing appointed by the Company. 
 “Reference Treasury Dealer” means: (a) J.P. Morgan Securities LLC, Morgan Stanley & Co. LLC, Citigroup Global Markets Inc or Deutsche Bank Securities Inc. and each of
their respective successors; provided that, if any such Reference Treasury Dealer ceases to be a primary U.S. Government securities dealer in the United States (“Primary Treasury Dealer”), the Company will substitute another Primary
Treasury Dealer; and (b) up to one other Primary Treasury Dealer selected by the Company. 
 “Reference Treasury
Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by an Independent Investment Banker, 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 an Independent Investment Banker at 3:00 p.m., New York City time, on the third business day preceding such redemption date. 

In the event of redemption of this Security in part only, a new Security or Securities of this series and of like tenor for the
unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof. 
 The Indenture
permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the Guarantors and the rights of the Holders of the Securities of each series to be affected under the
Indenture at any time by the Company and the Guarantors and the Trustee with the consent of the Holders of a majority in aggregate principal amount of the Securities at the time Outstanding of each series to be affected. The Indenture also contains
provisions permitting the Holders of specified percentages in aggregate principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company and the
Guarantors with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future
Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security. 

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to pay the principal of (and premium, if any) and interest on this Security at the times, place(s) and rate, and in the coin or currency, herein prescribed. 

This Global Security or portion hereof may not be exchanged for Definitive Securities of this series except in the limited circumstances
provided in the Indenture. The holders of beneficial interests in this Global Security will not be entitled to receive physical delivery of Definitive Securities except as described in the Indenture and will not be considered the Holders thereof for
any purpose under the Indenture. 
 The Securities are issuable only in registered form without coupons in denominations of U.S.
$2,000 and any integral multiple of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this
series and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same. 
 No service
charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. 

  
 A-1-5








 Prior to due presentment of this Security for registration of transfer, the Company, the
Guarantors, the Trustee and any agent of the Company, the Guarantors or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and none of the
Company, the Guarantors, the Trustee nor any such agent shall be affected by notice to the contrary. 
 No recourse under or
upon any obligation, covenant or agreement of or contained in the Indenture or of or contained in any Security, or the Guarantees endorsed thereon, or for any claim based thereon or otherwise in respect thereof, or in any Security or in the
Guarantees, or because of the creation of any indebtedness represented thereby, shall be had against any incorporator, shareholder, member, officer, manager or director, as such, past, present or future, of the Company or the Guarantors or of any
successor Person, either directly or through the Company or the Guarantors or any successor Person, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment, penalty or otherwise; it being expressly
understood that all such liability is hereby expressly waived and released by the acceptance hereof and as a condition of, and as part of the consideration for, the Securities and the execution of the Indenture. 

The Indenture provides that the Company and the Guarantors (a) will be discharged from any and all obligations in respect of the
Securities (except for certain obligations described in the Indenture), or (b) need not comply with certain restrictive covenants of the Indenture, in each case if the Company or a Guarantor deposits, in trust, with the Trustee money or U.S.
Government Obligations (or a combination thereof) which through the payment of interest thereon and principal thereof in accordance with their terms will provide money, in an amount sufficient to pay all the principal of and interest on the
Securities, but such money need not be segregated from other funds except to the extent required by law. 
 As more fully
provided in the Indenture, no Holder may pursue any remedy under the Indenture unless the Trustee shall have failed to act after notice of an Event of Default and written request by Holders of at least 25% in principal amount of a series of the
Securities and the offer to the Trustee of indemnity satisfactory to it; however, such provision does not affect the right to sue for enforcement of any overdue payment on any Security. 

Except as otherwise defined herein, all terms used in this Security which are defined in the Indenture shall have the meanings assigned
to them in the Indenture. 
 Customary abbreviations may be used in the name of a Holder or any 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). 

The Company will furnish to any holder of record of this Security, upon written request, without charge, a copy of the Indenture.
Requests may be made to: Weatherford International Ltd., 2000 St. James Place, Houston, Texas 77056, Attention: Corporate Secretary. 
 This Security shall be governed by and construed in accordance with the laws of the State of New York without regard to any principles of conflicts of law thereof that would result in the application of
the laws of any other jurisdiction.

which the Securities are, and are to be, authenticated and delivered. As provided in the Indenture, the Securities may be issued in one or more series, which different series may be issued in various aggregate principal amounts, may mature at
different times, may bear interest, if any, at different rates, may be subject to different redemption provisions, if any, may be subject to different sinking, purchase or analogous funds, if any, may be subject to different covenants and Events of
Default and may otherwise vary as in the Indenture provided or permitted. This Security is one of the series designated on the face hereof. 
 This Security is the general, unsecured, senior obligation of the Company and is guaranteed pursuant to guarantees (the “Guarantees”) by each of the Guarantors on a joint and several
basis. The Guarantees are the general, unsecured, senior obligation of the Guarantors. 
 Commencing on October 17, 2041
(180 days prior to the Stated Maturity), the Securities are subject to redemption upon not less than 30 nor more than 60 days’ notice by mail, at any time, as a whole or in part, at the election of the Company at a Redemption Price equal
to 100% of the principal amount of Securities then outstanding to be redeemed, plus accrued and unpaid interest thereon to the redemption date. Prior to October 17, 2041 (180 days prior to the Stated Maturity), the Securities are subject to
redemption upon not less than 30 nor more than 60 days’ notice by mail, as a whole or in part, at the election of the Company at a Redemption Price equal to the greater of: (a) 100% of the principal amount of Securities then
outstanding to be redeemed, plus accrued and unpaid interest thereon to the redemption date; or (b) the sum of the present values of the remaining scheduled payments of principal and interest on the Securities then outstanding to be redeemed
(not including any portion of such payments of interest accrued as of the redemption date), discounted to the redemption date on a semi-annual basis (computed based on a 360-day year consisting of 12 30-day months) at the Adjusted Treasury Rate,
plus 40 basis points (0.40%), as calculated by an Independent Investment Banker, plus accrued and unpaid interest thereon to the redemption date; but interest installments whose Stated Maturity is on or prior to such Redemption Date will be payable
to the Holders of such Securities, or one or more Predecessor Securities, of record at the close of business on the relevant Record Dates referred to on the face hereof, all as provided in the Indenture. 

“Adjusted Treasury Rate” means, with respect to any redemption date: (a) the yield, under the heading which
represents the average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15(519)” or any successor publication which is published weekly by the Board of Governors of the Federal
Reserve System and which 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 (if no maturity is within three months before or after the remaining life, as defined below, yields for the two published maturities most closely corresponding to the 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 (b) 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 year equal to the semi-annual 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 such redemption date. The Adjusted Treasury Rate will be calculated on the third business day preceding the redemption date. 

  
 A-2-4








 “Comparable Treasury Issue” means the United States Treasury security
selected by an Independent Investment Banker as having a maturity comparable to the remaining term of the Securities to be redeemed 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 remaining term of such Securities. 
 “Comparable
Treasury Price” means (1) the average of five Reference Treasury Dealer Quotations for the redemption date, after excluding the highest and lowest Reference Treasury Dealer Quotations, or (2) if an Independent Investment Banker
obtains fewer than five such Reference Treasury Dealer Quotations, the average of all such quotations. 
 “Independent
Investment Banker” means J.P. Morgan Securities LLC, Morgan Stanley & Co. LLC, Citigroup Global Markets Inc. or Deutsche Bank Securities Inc. or any of their respective successors, as designated by the Company, or if all such firms
are unwilling or unable to serve as such, an independent investment and banking institution of national standing appointed by the Company. 
 “Reference Treasury Dealer” means: (a) J.P. Morgan Securities LLC, Morgan Stanley & Co. LLC, Citigroup Global Markets Inc. or Deutsche Bank Securities Inc. and each of their
respective successors; provided that, if any such Reference Treasury Dealer ceases to be a primary U.S. Government securities dealer in the United States (“Primary Treasury Dealer”), the Company will substitute another Primary Treasury
Dealer; and (b) up to one other Primary Treasury Dealer selected by the Company. 
 “Reference Treasury Dealer
Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by an Independent Investment Banker, 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 an Independent Investment Banker at 3:00 p.m., New York City time, on the third business day preceding such redemption date. 

In the event of redemption of this Security in part only, a new Security or Securities of this series and of like tenor for the
unredeemed portion hereof will be issued in the name of the Holder hereof upon the cancellation hereof. 
 The Indenture
permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the Guarantors and the rights of the Holders of the Securities of each series to be affected under the
Indenture at any time by the Company and the Guarantors and the Trustee with the consent of the Holders of a majority in aggregate principal amount of the Securities at the time Outstanding of each series to be affected. The Indenture also contains
provisions permitting the Holders of specified percentages in aggregate principal amount of the Securities of each series at the time Outstanding, on behalf of the Holders of all Securities of such series, to waive compliance by the Company and the
Guarantors with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future
Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security. 

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the
Company, which is absolute and unconditional, to pay the principal of (and premium, if any) and interest on this Security at the times, place(s) and rate, and in the coin or currency, herein prescribed. 

This Global Security or portion hereof may not be exchanged for Definitive Securities of this series except in the limited circumstances
provided in the Indenture. The holders of beneficial interests in this Global Security will not be entitled to receive physical delivery of Definitive Securities except as described in the Indenture and will not be considered the Holders thereof for
any purpose under the Indenture. 
 The Securities are issuable only in registered form without coupons in denominations of U.S.
$2,000 and any integral multiple of $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this
series and of like tenor of a different authorized denomination, as requested by the Holder surrendering the same. 
 No service
charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith. 

  
 A-2-5








 Prior to due presentment of this Security for registration of transfer, the Company, the
Guarantors, the Trustee and any agent of the Company, the Guarantors or the Trustee may treat the Person in whose name this Security is registered as the owner hereof for all purposes, whether or not this Security be overdue, and none of the
Company, the Guarantors, the Trustee nor any such agent shall be affected by notice to the contrary. 
 No recourse under or
upon any obligation, covenant or agreement of or contained in the Indenture or of or contained in any Security, or the Guarantees endorsed thereon, or for any claim based thereon or otherwise in respect thereof, or in any Security or in the
Guarantees, or because of the creation of any indebtedness represented thereby, shall be had against any incorporator, shareholder, member, officer, manager or director, as such, past, present or future, of the Company or the Guarantors or of any
successor Person, either directly or through the Company or the Guarantors or any successor Person, whether by virtue of any constitution, statute or rule of law, or by the enforcement of any assessment, penalty or otherwise; it being expressly
understood that all such liability is hereby expressly waived and released by the acceptance hereof and as a condition of, and as part of the consideration for, the Securities and the execution of the Indenture. 

The Indenture provides that the Company and the Guarantors (a) will be discharged from any and all obligations in respect of the
Securities (except for certain obligations described in the Indenture), or (b) need not comply with certain restrictive covenants of the Indenture, in each case if the Company or a Guarantor deposits, in trust, with the Trustee money or U.S.
Government Obligations (or a combination thereof) which through the payment of interest thereon and principal thereof in accordance with their terms will provide money, in an amount sufficient to pay all the principal of and interest on the
Securities, but such money need not be segregated from other funds except to the extent required by law. 
 As more fully
provided in the Indenture, no Holder may pursue any remedy under the Indenture unless the Trustee shall have failed to act after notice of an Event of Default and written request by Holders of at least 25% in principal amount of a series of the
Securities and the offer to the Trustee of indemnity satisfactory to it; however, such provision does not affect the right to sue for enforcement of any overdue payment on any Security. 

Except as otherwise defined herein, all terms used in this Security which are defined in the Indenture shall have the meanings assigned
to them in the Indenture. 
 Customary abbreviations may be used in the name of a Holder or any 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). 

The Company will furnish to any holder of record of this Security, upon written request, without charge, a copy of the Indenture.
Requests may be made to: Weatherford International Ltd., 2000 St. James Place, Houston, Texas 77056, Attention: Corporate Secretary. 
 This Security shall be governed by and construed in accordance with the laws of the State of New York without regard to any principles of conflicts of law thereof that would result in the application of
the laws of any other jurisdiction.
