**Item 1.01 Entry into a Material Definitive Agreement.**

As previously disclosed, on November 4, 2025, Nabors Industries, Inc. ("NII") entered into a purchase agreement (the "Purchase Agreement") under which NII agreed to sell $700 million aggregate principal amount of its 7.625% Senior Priority Guaranteed Notes due 2032 (the "Notes") to Goldman Sachs & Co. LLC, Morgan Stanley & Co. LLC, Citigroup Global Markets Inc., Wells Fargo Securities, LLC, HSBC Securities (USA) Inc., Blaylock Van, LLC and Nomura Securities International, Inc. (together, the "Initial Purchasers").

The Notes are fully and unconditionally guaranteed, jointly and severally, by each of the entities that guarantee NII's existing 9.125% senior priority guaranteed notes due 2030 (the "Existing Senior Priority Guaranteed Notes"), which includes (i) Nabors Industries Ltd. ("Nabors Bermuda"), (ii) each of the subsidiaries that guarantee Nabors Bermuda's existing 7.50% senior guaranteed notes due 2028 and NII's existing 8.875% senior guaranteed notes due 2031 (together, the "Existing Senior Guaranteed Notes") and (iii) certain lower-tier subsidiaries of Nabors Bermuda that guarantee NII's amended & restated revolving credit facility (the "A&R Credit Facility") but do not currently guarantee the Existing Senior Guaranteed Notes, other than Nabors Alaska Drilling, Inc. (the "Lower Tier Notes Guarantors" and, together with Nabors Bermuda and the guarantors of the Existing Senior Guaranteed Notes, the "Guarantors") on the same basis as the guarantee of the Existing Senior Priority Guaranteed Notes.

The closing of the sale of the Notes occurred on November 10, 2025. NII received net proceeds, after deducting estimated offering commissions and estimated net expenses, of approximately $687.9 million. Nabors Bermuda intends to use the net proceeds from this offering to retire all of its outstanding 7.375% senior priority guaranteed notes due 2027 (the "Senior Priority Guaranteed Notes due 2027"). The remaining proceeds will be used for general corporate purposes. As of the date hereof, there are $546.1 million in aggregate principal of Senior Priority Guaranteed Notes due 2027 outstanding.

NII sold the Notes to the Initial Purchasers in reliance on the exemption from registration provided by Section 4(a)(2) of the Securities Act of 1933, as amended (the "Securities Act"). The Initial Purchasers then sold the Notes to (i) qualified institutional buyers pursuant to the exemption from registration provided by Rule 144A and (ii) pursuant to Regulation S under the Securities Act. NII relied on these exemptions from registration based in part on representations made by the Initial Purchasers in the Purchase Agreement.

The Notes are governed by an indenture, dated as of November 10, 2025 (the "Indenture"), among NII, as issuer, the Guarantors, as guarantors, and Wilmington Trust, National Association, as trustee.

The Notes will bear interest at an annual rate of 7.625% and will mature on November 15, 2032. The Indenture includes customary covenants, subject to significant exceptions, that limit the ability of Nabors Bermuda and its subsidiaries to, among other things, incur certain liens, enter into sale and leaseback transactions, incur debt and engage in certain asset transfers. In the event of a Change of Control Triggering Event (as defined in the Indenture) with respect to the Notes, the holders of the Notes may require NII to purchase all or a portion of their Notes at a purchase price equal to 101% of the principal amount of the Notes so purchased, plus accrued and unpaid interest, if any.

Prior to November 15, 2028, NII may redeem the Notes, in whole or in part, at a price equal to 100% of the principal amount thereof plus a "make-whole" premium and accrued and unpaid interest, if any. On or after November 15, 2028, NII may redeem the Notes, in whole or in part, at specified prices that decline over time, plus accrued and unpaid interest, if any. In addition, NII may use the net cash proceeds of one or more equity offerings to redeem up to 35% of the aggregate principal amount of Notes prior to November 15, 2028, at a price equal to 107.625% of the principal amount thereof plus accrued and unpaid interest, if any.

The Notes are senior unsecured obligations of NII and will rank *pari passu* in right of payment with all of NII's existing and future unsubordinated debt and other obligations, except that the Notes are (i) effectively junior in right of payment to any of NII's existing and future secured obligations, including secured obligations under the A&R Credit Facility, to the extent of the value of the collateral securing such obligations thereunder, (ii) senior in right of payment to any of NII's future subordinated debt and other obligations that are expressly subordinated to the Notes and (iii) structurally subordinated to the obligations of creditors, including trade creditors, of Nabors Bermuda's subsidiaries that do not guarantee the Notes.

The guarantees of the Notes are (i) senior unsecured obligations of each Guarantor, other than the guarantees of the Lower Tier Notes Guarantors, which are subordinate in right of payment to guarantees by the Lower Tier Notes Guarantors of certain senior guaranteed debt, (ii) rank *pari passu* in right of payment with all existing and future senior obligations of the Guarantors that are not subordinated in right of payment to the guarantees, other than the guarantees of the Lower Tier Notes Guarantors, which are subordinate in right of payment to guarantees by the Lower Tier Notes Guarantors of certain senior guaranteed debt, (iii) senior in right of payment to all future obligations of the Guarantors that are expressly subordinated in right of payment of the guarantees, (iv) effectively subordinated to all existing and future secured obligations of the Guarantors to the extent of the value of the property and assets securing such obligations, including secured obligations under the A&R Credit Facility, and (v) structurally subordinated to any existing and future obligations of any of such Guarantor's subsidiaries that are not Guarantors.

A copy of the Indenture is included in this Form 8-K as Exhibit 4.1 and incorporated herein by reference. The summary description of the Indenture in this report is qualified in its entirety by reference to Exhibit 4.1.

The Securities, any notations thereon relating to the Guarantees and the Trustee's certificate of authentication shall be substantially in the form of Exhibit A hereto. The Securities may have notations, legends or endorsements required by law, securities exchange rule, the Company's certificate of incorporation, memorandum of association, by-laws, agreements to which the Company is subject, if any, or usage; *provided* that any such notation, legend or endorsement is in a form acceptable to the Company. Each Security shall be dated the date of its authentication.

However, to the extent any provision of any Security conflicts with the express provisions of this Indenture, the provisions of this Indenture (to the extent permitted by law) shall govern and be controlling.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) *Global Securities*. Securities issued in global form shall be substantially in the form of Exhibit A (in each case including the Global Security Legend thereon and the Schedule of Exchanges of Interests in the Global Security attached thereto). Securities issued in definitive form shall be substantially in the form of Exhibit A (but without, in each case, the Global Security Legend thereon and without the Schedule of Exchanges of Interests in the Global Security attached thereto). Each Global Security shall represent such of the outstanding Securities as shall be specified therein, and each shall provide that it shall represent the aggregate principal amount of outstanding Securities from time to time endorsed thereon and that the aggregate principal amount of outstanding Securities represented thereby may from time to time be reduced or increased, as appropriate, to reflect exchanges and redemptions. Any endorsement of a Global Security to reflect the amount of any increase or decrease in the aggregate principal amount of outstanding Securities represented thereby shall be made by the Securities Custodian, in accordance with written instructions given by the Holder thereof as required by Section 2.06.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) *Regulation S Global Securities*. Any Securities initially offered and sold in reliance on Regulation S shall be issued initially in the form of a Regulation S Global Security, which shall be deposited on behalf of the purchasers of the Securities represented thereby with the Securities Custodian, and registered in the name of the Depositary or the nominee of the Depositary, duly executed by the Company and authenticated by the Trustee as hereinafter provided.

If an Officer of the Company whose signature is on this Indenture or a Security no longer holds that office at the time the Trustee authenticates such Security or at any time thereafter, the Security shall be valid nevertheless.

A Security shall not be entitled to any benefit under this Indenture or be valid or obligatory for any purpose until authenticated by the manual signature of an authorized signatory of the Trustee or an authenticating agent, as the case may be, which signature shall be conclusive evidence that the Security has been authenticated under this Indenture.

The Trustee shall authenticate and deliver: (1) on the date hereof, Initial Securities for original issue in an aggregate principal amount of $700,000,000 and (2) if and when issued, Additional Securities, in each case upon a written order of the Company signed by one Officer of the Company.

The Company may issue Additional Securities under this Indenture subsequent to the Issue Date; *provided* that a separate CUSIP will be used for any Additional Securities that are not "fungible" for U.S. federal income tax purposes with the Securities issued on the Issue Date. In authenticating such Securities, the Trustee shall receive, and shall be entitled to conclusively rely upon, an Opinion of Counsel substantially to the effect that such Securities and the related Guarantees, when authenticated and delivered by the Trustee and issued by the Company and the Guarantors, respectively, in the manner and subject to any conditions specified in such Opinion of Counsel, will constitute valid and legally binding obligations of the Company and the Guarantors, as the case may be, enforceable in accordance with their respective terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and similar laws of general applicability relating to or affecting creditors' rights and to general equity principles.

The aggregate principal amount of Securities outstanding at any time may not exceed the aggregate principal amount of Securities authorized for issuance by the Company pursuant to such written orders of the Company, except as provided in Section 2.07. Subject to the foregoing, the aggregate principal amount of Securities that may be issued under this Indenture shall not be limited.

The Trustee may appoint one or more authenticating agents acceptable to the Company to authenticate Securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) *General Provisions Relating to Transfers and Exchanges*.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) To permit registrations of transfers and exchanges, the Company shall execute and the Trustee shall authenticate or cause to be authenticated Global Securities and Definitive Securities upon the Company's order or at the Registrar's request.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) All Global Securities and Definitive Securities issued upon any registration of transfer or exchange of Global Securities or Definitive Securities shall be the valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Global Securities or Definitive Securities surrendered upon such registration of transfer or exchange.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(7) The Trustee shall authenticate or cause to be authenticated Global Securities and Definitive Securities upon receipt of a written order of the Company signed by one of its Officers and in accordance with the other provisions of Section 2.02 to the extent applicable.

The Trustee may conclusively rely and shall be fully protected in relying upon information furnished by the Depositary with respect to its members, participants and any beneficial owners.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(10) Neither the Trustee nor any Agent shall have any responsibility or liability for any actions taken or not taken by the Depositary. Each Holder agrees to indemnify the Company and the Trustee against any liability that may result from the transfer, exchange or assignment of such Holder's Security in violation of any provision of this Indenture and/or applicable United States Federal or state securities law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(11) The transferor of any Security shall provide or cause to be provided to the Trustee all information reasonably necessary to allow the Trustee to comply with any applicable tax reporting obligations, including without limitation any cost basis reporting obligations under Section 6045 of the Code. The Trustee may conclusively rely on information provided to it and shall have no responsibility to verify or ensure the accuracy of such information. In connection with any proposed exchange of a Definitive Security for a Global Security, the Company or the Depositary shall be required to provide or cause to be provided to the Trustee all information reasonably necessary to allow the Trustee to comply with any applicable tax reporting obligations, including without limitation any cost basis reporting obligations under Section 6045 of the Code. The Trustee may conclusively rely on information provided to it and shall have no responsibility to verify or ensure the accuracy of such information.

SECTION 2.07. *Replacement Securities*. If a mutilated Security is surrendered to the Registrar or if the Holder of a Security claims that the Security has been lost, destroyed or wrongfully taken, the Company shall issue and the Trustee shall authenticate a replacement Security if the requirements of Section 8-405 of the Uniform Commercial Code are met, such that the Holder (a) satisfies the Company or the Trustee within a reasonable time after such Holder has notice of such loss, destruction or wrongful taking and the Registrar does not register a transfer prior to receiving such notification, (b) makes such request to the Company or Trustee prior to the Security being acquired by a protected purchaser as defined in Section 8-303 of the Uniform Commercial Code (a "protected purchaser") and (c) satisfies any other reasonable requirements of the Trustee. Such Holder must furnish an indemnity bond that is sufficient in the judgment of the Trustee and the Company to protect the Company, the Trustee, any Agent or any authenticating agent from any loss which any of them may suffer if a Security is replaced. The Company and the Trustee may charge for their expenses in replacing a Security. If, after the delivery of such replacement Security, a protected purchaser of the original Security in lieu of which such replacement Security was issued presents for payment or registration such original Security, the Trustee shall be entitled to recover such replacement Security from the Person to whom it was delivered or any Person taking therefrom, except a protected purchaser, and shall be entitled to recover upon the security or indemnity provided therefor to the extent of any loss, damage, cost or expense incurred by the Trustee or the Company in connection therewith. Every replacement Security is a contractual obligation of the Company.

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

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

SECTION 2.08. *Outstanding Securities*. The Securities outstanding at any time are all the Securities authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in the interest in a Global Security effected by the Registrar hereunder and those described in this Section 2.08 as not outstanding; *provided*, *however*, that in determining whether the Holders of the requisite principal amount of outstanding Securities are present at a meeting of Holders of Securities for quorum purposes or have consented to or voted in favor of any request, demand, authorization, direction, notice, consent, waiver, amendment or modification hereunder, Securities held for the account of the Company or any of its Affiliates shall be disregarded and deemed not to be outstanding, except that in determining whether the Trustee shall be protected in making such a determination or relying upon any such quorum, consent or vote, only Securities which a Responsible Officer of the Trustee actually knows to be so owned shall be so disregarded.

If a Security is replaced pursuant to Section 2.07, it ceases to be outstanding unless the Trustee receives proof satisfactory to it that the replaced Security is held by a protected purchaser.

If the principal amount of any Security is considered paid under Section 3.01, it ceases to be outstanding and interest on it ceases to accrue.

SECTION 2.09. [*Reserved*]

SECTION 2.10. *Temporary Securities*. Until Definitive Securities are ready for delivery, the Company may prepare and the Trustee shall authenticate or cause to be authenticated temporary Securities. Temporary Securities shall be substantially in the form of Definitive Securities, but may have variations that the Company considers appropriate for temporary Securities. Without unreasonable delay, the Company shall prepare and the Trustee shall authenticate Definitive Securities in exchange for temporary Securities. Until so exchanged, temporary Securities shall in all respects be entitled to the same benefits under this Indenture as Definitive Securities.

SECTION 2.11. *Cancellation*. The Company or the Guarantors at any time may deliver Securities to the Trustee for cancellation. The Registrar and the Paying Agent shall forward to the Trustee any Securities surrendered to them for registration of transfer, exchange or payment. The Trustee, upon written Company Order, shall cancel all Securities surrendered for registration of transfer, exchange, payment, replacement or cancellation. All canceled Securities held by the Trustee shall be disposed of in accordance with its customary practice (subject to the record retention requirements of the Exchange Act). The Company may not issue new Securities to replace Securities that have been paid or that have been delivered to the Trustee for cancellation.

SECTION 2.12. *Defaulted Interest*. If the Company defaults in a payment of interest on the Securities, it shall pay the defaulted interest in any lawful manner plus, to the extent lawful, interest on the defaulted interest, in each case at the rate provided in the Securities and in the manner provided in Section 3.01. The Company may pay the defaulted interest to the Persons who are Holders on a subsequent special record date. At least 15 days before any special record date, the Company (or the Trustee, in the name of and at the expense of the Company) shall send to Holders a notice that states the special record date, the related payment date and the amount of such interest to be paid. The Trustee will not have any duty to determine whether any defaulted interest is payable or the amount thereof.

SECTION 2.13. *Persons Deemed Owners*. The Company, the Guarantors, the Trustee, any Agent and any authenticating agent may treat the Person in whose name any Security is registered as the owner of such Security for the purpose of receiving payments of principal of or premium, if any, Additional Amounts, if any, or interest on such Security and for all other purposes. None of the Company, the Guarantors, the Trustee, any Agent or any authenticating agent shall be affected by any notice to the contrary.

SECTION 2.14. *CUSIP Numbers*. The Company in issuing the Securities may use "CUSIP," "ISIN" or similar numbers (if then generally in use), and, if so, the Trustee shall use such numbers in notices of redemption as a convenience to Holders; *provided* that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Securities or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Securities, and any such redemption shall not be affected by any defect in or omission of such numbers. The Company will promptly notify the Trustee in accordance with Section 11.02 of any change in any such number.

**ARTICLE III** **<br> COVENANTS**

SECTION 3.01. *Payment of Securities*. The Company shall pay the principal of and premium, if any, Additional Amounts, if any, and interest on the Securities on the dates and in the manner provided in the Securities and this Indenture.

Further, to the extent lawful, the Company shall pay interest on overdue principal, premium, if any, Additional Amounts, if any, and interest (without regard to any applicable grace period), from time to time on demand at the rate then in effect on the Securities.

SECTION 3.02. *Maintenance of Office or Agency*. So long as any of the Securities shall remain outstanding, the Company will, in accordance with Section 2.03, maintain an office or agency (which may be an office of the Trustee or an affiliate of the Trustee, or the Registrar) in the continental United States where the Securities may be surrendered for exchange or registration of transfer as provided in this Indenture, where notices and demands to or upon the Company in respect to the Securities may be served, and where the Securities may be presented or surrendered for payment. The Company may also from time to time designate one or more other offices or agencies in the continental United States where Securities may be presented or surrendered for any and all such purposes and may from time to time rescind such designations; *provided*, *however*, that no such designation or rescission shall in any manner relieve the Company of its obligation under Section 2.03 to maintain an office or agency in The City of New York where any Securities may be presented or surrendered for payment. The Company will give to the Trustee prompt written notice in accordance with Section 11.02 of the location of any such office or agency and of any change of location thereof. In case the Company shall fail to maintain any such office or agency or shall fail to give such notice of the location or of any change in the location thereof, such surrenders, presentations and demands may be made and notices may be served at the office of the Trustee indicated in Section 11.02, and the Company hereby appoints the Trustee its agent to receive at the aforesaid office all such surrenders, presentations, notices and demands; *provided*, *however*, that no service of legal process on the Company may be made at any office of the Trustee.

SECTION 3.03. *SEC Reports; Financial Statements*.

Notwithstanding the foregoing, a transaction shall not be deemed to involve a "Change of Control" under clause (c) above if (i) Nabors Bermuda becomes a direct or indirect wholly owned Subsidiary of a holding company and (ii)(A) the direct or indirect holders of the Voting Stock of such holding company immediately following such transaction are substantially the same as the holders of the Voting Stock of Nabors Bermuda immediately prior to such transaction or (B) immediately following such transaction no "person" (as that term is used in Section 13(d)(3) of the Exchange Act) (other than a holding company satisfying the requirements of this sentence) is the "beneficial owner" (as defined in Rules 13d-3 and 13d-5 under the Exchange Act), directly or indirectly, of more than 50% of the outstanding Voting Stock of such holding company, measured by voting power rather than number of shares.

For purposes of this Section 3.10, the term "Change of Control Triggering Event" means the ratings of the Securities are lowered by at least two of the three Rating Agencies and, immediately following such lowering, the Securities are not rated Investment Grade by at least two of the three Rating Agencies in any case on any date during the period (the "Trigger Period") commencing on the date of the first public announcement by the Company or Nabors Bermuda of any Change of Control (or pending Change of Control) and ending 60 days following consummation of such Change of Control (which 60-day period will be extended for so long as the rating of the Securities is under publicly announced consideration for a possible downgrade as a result of the Change of Control by any of the Rating Agencies); *provided*, *however*, that if the Securities are not rated by all three Rating Agencies, then a "Change of Control Triggering Event" shall occur if the ratings of the Securities are lowered by at least one of the Rating Agencies and, immediately following such lowering, the Securities are not rated Investment Grade by at least one of the Rating Agencies in any case on any date during the Trigger Period. Notwithstanding the foregoing, no Change of Control Triggering Event will be deemed to have occurred in connection with any particular Change of Control unless and until such Change of Control has actually been consummated.

Within 60 days following the date upon which the Change of Control Triggering Event has occurred, or at the Company's option, prior to any Change of Control but after the public announcement of the transaction that constitutes or may constitute the Change of Control, except to the extent that the Company shall have exercised its right to redeem the Securities pursuant to Section 10.07, the Company shall send a notice (a "Change of Control Offer") to each Holder of Securities with a copy to the Trustee, which notice will govern the terms of the Change of Control Offer, stating:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) that a Change of Control Triggering Event has occurred and that such Holder has the right to require the Company to purchase such Holder's Securities at a purchase price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to the date of purchase (subject to the right of holders of record on a record date to receive interest on the relevant Interest Payment Date as provided in the first paragraph of this Section 3.10);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) the circumstances regarding such Change of Control Triggering Event;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) the purchase date (which shall be (i) no earlier than 30 days nor later than 60 days from the date such notice is sent, if sent after consummation of the Change of Control and (ii) on the date of the Change of Control, if such notice is sent prior to consummation of the Change of Control, in each case, other than as may be required by law) (such date, the "Change of Control Payment Date"); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) the instructions that a Holder must follow in order to have its Securities purchased.

Holders of Securities electing to have such Securities purchased pursuant to a Change of Control Offer must surrender their Securities with the form entitled "Option of Holder to Elect Purchase" on the reverse of the Security completed, to the Paying Agent at the address specified in the notice, or transfer their Securities to the Paying Agent by book-entry transfer pursuant to the Applicable Procedures, prior to the close of business on the third Business Day prior to the Change of Control Payment Date.

On the Change of Control Payment Date, all Securities purchased by the Company under this Section shall be delivered to the Trustee for cancellation, and the Company shall pay the purchase price plus accrued and unpaid interest to the Holders entitled thereto.

The Company may make a Change of Control Offer in advance of a Change of Control and the Change of Control Payment Date, and its Change of Control Offer may be conditioned upon 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.

If Holders of not less than 90% in aggregate principal amount of the 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 the 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 all of the Securities that remain outstanding following such purchase at a redemption price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, up to, but excluding, the date of redemption (subject to the right of Holders of record on the relevant record date to receive interest on the relevant Interest Payment Date).

Any redemption pursuant to this Section 3.10 shall be made, to the extent applicable, pursuant to the procedures set forth in Sections 10.01 through 10.06.

The Company shall have no obligation 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 of this Section 3.10 for such an offer made by the Company, and such third party purchases all Securities properly tendered and not withdrawn under its offer.

The Company shall comply, to the extent applicable, with the requirements of Section 14(e) of the Exchange Act and any other securities laws or regulations in connection with the repurchase of Securities pursuant to a Change of Control Offer. To the extent that the provisions of any securities laws or regulations conflict with this Section 3.10, the Company shall comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations by virtue thereof.

SECTION 3.11. *Limitations on Subsidiary Debt*.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) For so long as any Securities are outstanding, Nabors Bermuda will not permit any of its Subsidiaries to incur, directly or indirectly, any Debt other than:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) existing Debt of a Subsidiary of Nabors Bermuda outstanding on the date of issuance of the Securities (other than Debt described in clauses (vii)(A), (viii) or (xiv) of this Section 3.11(a));

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) intercompany loans and advances between or among Nabors Bermuda and its Subsidiaries; *provided* that (a) if the obligor on such intercompany loan or advance is a Guarantor, then such Debt must be expressly subordinated to the prior payment in full in cash of all obligations with respect to the Guarantee of such Guarantor; and (b)(i) any subsequent issuance or transfer of Capital Stock that results in any such Debt being held by a Person other than Nabors Bermuda or a Subsidiary of Nabors Bermuda and (ii) any sale or other transfer of any such Debt to a Person that is not Nabors Bermuda or a Subsidiary of Nabors Bermuda, will be deemed, in each case, to constitute an incurrence of such Debt by such Subsidiary that was not permitted by this clause (2); *provided*, *further*, that (x) notwithstanding the foregoing, the Guarantors may owe such Debt to Nabors Bermuda or any such Subsidiary up to an aggregate principal amount at any one time outstanding under this clause (ii) of $100,000,000 that is not subject to such subordination terms and (y) that any such standalone subordination or intercreditor agreement or such other arrangement shall permit payments in respect of such intercompany indebtedness as long as no Event of Default shall have occurred and be continuing;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) Debt under any Interest Rate Protection Agreements or any Currency Rate Protection Agreements;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) Debt (i) under unsecured lines of credit for overdrafts or for working capital purposes in foreign countries with financial institutions, and (ii) arising from the honoring by a bank or other Person of a check, draft or similar instrument inadvertently drawing against insufficient funds;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(v) Debt of a Person existing at the time such Person becomes a Subsidiary of Nabors Bermuda or is merged, consolidated or amalgamated with or into Nabors Bermuda or any Subsidiary of Nabors Bermuda; *provided* that any such Debt was not incurred in contemplation of any such transaction;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vi) Debt of any Guarantor that is subordinate in right of payment to the Guarantee of such Guarantor;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vii) (A) Debt in an aggregate amount not to exceed $500.0 million represented by (i) the Securities and the Guarantees and (ii) the Existing Senior Priority Guaranteed Notes and other Debt having the same obligors as the Securities and the Guarantees and issued by the Company or Nabors Bermuda and (B) Junior Guaranteed Debt, including in each case any refinancing of such Debt incurred under clause (xiv), *provided* that after giving effect to any such refinancing, the principal amount of Debt incurred pursuant to clause (vii) (A) in the aggregate and at any time outstanding does not exceed $500.0 million and *provided, further*, that, for the avoidance of doubt, any refinancing of Debt incurred pursuant to clause (vii)(A) has the same obligors as the Securities and the Guarantees and such Debt is issued or incurred by the Company or Nabors Bermuda;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(viii) Debt incurred pursuant to Credit Facilities in an aggregate amount at any one time outstanding under this clause (viii), together with any refinancing of such Debt incurred under clause (xiv), not to exceed an amount equal to (A) the greater of (i) $1.70 billion and (ii) 10.0% of Consolidated Net Tangible Assets, less (B) the total Aggregate Debt outstanding at the time of such incurrence (without double counting for Aggregate Debt incurred under this clause (viii)), measured at the time of incurrence of any such Debt and after giving effect to such incurrence, less (C) outstanding Debt incurred or described under clause (vii)(A) of this Section 3.11.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ix) Debt in respect of current accounts payable and accrued expenses incurred in the ordinary course of business;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(x) Debt, which may include purchase money Debt, capital lease or finance lease obligations or mortgage financings, incurred to finance the purchase, installation, construction, design or improvement, or capital lease or finance lease of assets (including equipment) or property (real or personal) (whether through the direct purchase of assets or the capital stock of any person owning such assets) and related Taxes and transaction costs; *provided* that (i) such Debt when incurred shall not exceed 85% of the purchase price of the asset(s) or person financed and all fees, premium, costs and expenses relating thereto, including attorney and legal, accounting, expert, and professional advisor fees and expenses; and (ii) no such Debt shall be refinanced for a principal amount in excess of the principal balance outstanding thereon at the time of such refinancing plus all fees, premium, costs and expenses relating thereto, including attorney and legal, accounting, expert, and professional advisor fees and expenses;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(xi) Debt under performance guaranties, performance bonds and letters of credit issued in the ordinary course of business and serving as a financial or performance guaranty (other than as a guaranty of Debt for borrowed money);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(xii) Debt under documentary credits issued in connection with the purchase of goods in the ordinary course of business;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(xiii) Debt in respect of any Permitted Accounts Receivables Sales Facility; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(xiv) any refinancing of Debt incurred pursuant to the foregoing clauses (i), (v), (vii), (viii) and this clause (xiv); *provided* that (i) such refinancing Debt will not exceed the principal amount of Debt so refinanced plus an amount necessary to pay fees and expenses, including premiums, related to such refinancing (ii) the scheduled maturity date thereof is not shortened (except to the extent such shortened maturity date is subsequent to the Stated Maturity and (iii) such refinancing Debt and any guarantees thereof are incurred solely by the obligors and guarantors, if any, of the Debt so refinanced).

Nabors Bermuda will not permit any of the Guarantors to incur, directly or indirectly, any Debt that is subordinated or junior in right of payment to other Debt of such Guarantor and senior in any respect in right of payment to the Guarantees of the Securities.

Debt permitted by this Section 3.11(a) need not be permitted solely by reference to one provision permitting such Debt but may be permitted in part by one such provision and in part by one or more other provisions of this Section 3.11(a) permitting such Debt. In the event that an item of Debt meets the criteria of more than one of the types of Debt described in this Section 3.11(a), the Company will be permitted, in its sole discretion, to divide, classify or reclassify all or a portion of such item of Debt and only be required to include the amount of such Debt in one of such clauses. For the avoidance of doubt, the Receivables Purchase, the Receivables Sale Agreement, and related transaction documents do not constitute Debt.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) This covenant shall not apply during such time as the Securities are rated Investment Grade by at least two of the three Rating Agencies and no Default or Event of Default has occurred and is continuing under this Indenture. The Trustee shall not have any obligation to monitor the ratings of the Securities.

SECTION 3.12. *Limitations on Asset Transfers.*

Nabors Bermuda shall not permit any of the Lower Tier Notes Guarantors or any of their respective Subsidiaries to directly or indirectly convey, sell, lease, assign, sell and leaseback, transfer (including by way of investment) or otherwise dispose of any drilling related fixed assets, including drilling rigs, drilling-related services assets or related assets (including, without limitation, any Capital Stock of any Subsidiary or any interest in a joint venture that owns such assets), whether now owned or hereafter acquired (each a "Rig Disposition"), to (i) Nabors Bermuda, (ii) any Subsidiary of Nabors Bermuda that is not Nabors Drilling Technologies USA, Inc., Nabors Lux 2 S.à r.l., Canrig Drilling Technology Canada Ltd. or Nabors International Management Limited (together, the "Original Lower Tier Notes Guarantors") or (iii) any joint venture directly held by Nabors Bermuda or a Subsidiary or parent (direct or indirect) of Nabors Bermuda, excluding any joint venture directly or indirectly held by any Original Lower Tier Notes Guarantor or a Subsidiary of such Guarantor, unless such Rig Disposition is to (x) an Original Lower Tier Notes Guarantor, (y) a Subsidiary of an Original Lower Tier Notes Guarantor or (z) a Subsidiary of Nabors Bermuda that is not a Guarantor of any Existing Notes; *provided* that prior to or contemporaneous with such Rig Disposition pursuant to this clause (z), such Subsidiary executes and delivers to the Trustee a supplemental indenture pursuant to which such Subsidiary shall become a Guarantor under this Indenture and the related Guarantee shall be of the same priority as the existing Guarantees of the Lower Tier Notes Guarantors; *provided*, *further* that Rig Dispositions to Transitory Subsidiary Owners shall not be prohibited for so long as such Subsidiary is a Transitory Subsidiary Owner and no Subsidiary that is a Transitory Subsidiary Owner will be required to become a Guarantor for so long as such Subsidiary is a Transitory Subsidiary Owner. In addition, Nabors Bermuda shall not permit any of the Lower Tier Notes Guarantors and any of their respective Subsidiaries to make any Rig Disposition to any direct or indirect parent of Nabors Bermuda.

Net proceeds of any Rig Dispositions to Persons that are not Affiliates of Nabors Bermuda (other than joint ventures directly held by Nabors Bermuda or a Subsidiary or parent (direct or indirect) of Nabors Bermuda, excluding any joint venture directly or indirectly held by any Original Lower Tier Notes Guarantor or a Subsidiary of such Guarantor) received by the Lower Tier Notes Guarantors or any of their Subsidiaries during any twelve month period which are not retained or used in the business or operations of the Original Lower Tier Notes Guarantors or their Subsidiaries (such amounts collectively, "Excess Rig Proceeds"), shall not exceed a total amount of $50.0 million in the aggregate in any twelve month period; *provided* that Excess Rig Proceeds may be transferred to Nabors Bermuda or any Subsidiary of Nabors Bermuda on a temporary basis for tax or other reasons in the ordinary course of such Subsidiary's business for a period of up to twenty Business Days and the full amount of such Excess Rig Proceeds shall be returned to an Original Lower Tier Notes Guarantors or any of their Subsidiaries no later than twenty Business Days following such transfer of such Excess Rig Proceeds.

SECTION 3.13. *Future Guarantors.*

After the Issue Date, if any Subsidiary of Nabors Bermuda (other than the Company and certain entities incorporated or established in Luxembourg as provided in Section 9.04) or any direct or indirect parent of Nabors Bermuda that is not then a Guarantor guarantees the Existing Notes or the Existing Senior Priority Guaranteed Notes then, such Subsidiary or such direct or indirect parent of Nabors Bermuda, as the case may be, within twenty Business Days of the date that such indebtedness has been guaranteed, shall execute and deliver to the Trustee a supplemental indenture pursuant to which such Subsidiary or such direct or indirect parent of Nabors Bermuda, as the case may be, shall become a Guarantor under this Indenture and provide for a Guarantee by such Subsidiary or such direct or indirect parent of Nabors Bermuda, as the case may be, on the same terms and conditions as those set forth herein (including, without limitation, the same priority as the existing Guarantees of a Guarantor that is not a Lower Tier Notes Guarantor).

**ARTICLE IV** **<br> CONSOLIDATION, MERGER AND SALE**

SECTION 4.01. *Limitation on Mergers and Consolidations*. The Company shall not consolidate or amalgamate with or merge into any other Person or convey, transfer or lease its properties and assets substantially as an entirety to any Person unless:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) the Person formed by such consolidation or amalgamation or into which the Company is merged or the Person which acquires by conveyance or transfer, or which leases, the properties and assets of the Company substantially as an entirety shall be a Person organized and existing under the laws of the United States of America, any State thereof or the District of Columbia, and shall expressly assume, by an indenture supplemental hereto, executed and delivered to the Trustee, in form reasonably satisfactory to the Trustee, the due and punctual payment of the principal of and interest on all the Securities and the performance of every covenant of this Indenture on the part of the Company to be performed;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) immediately after giving effect to such transaction, no Default or Event of Default shall have occurred and be continuing; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) the Company has delivered to the Trustee an Officer's Certificate and an Opinion of Counsel, each stating that such consolidation, amalgamation, merger, conveyance, transfer or lease and such supplemental indenture comply with this Article IV and that all conditions precedent herein provided for relating to such transaction have been complied with.

SECTION 4.02. *Successors Substituted*. Upon any consolidation or amalgamation of the Company with, or merger of the Company into, any other Person, or any conveyance, transfer or lease of the properties and assets of the Company substantially as an entirety in accordance with Section 4.01, the successor Person formed by such consolidation or amalgamation or into which the Company is merged or to which such conveyance, transfer or lease is made shall succeed to, and be substituted for, and may exercise every right and power of, the Company under this Indenture with the same effect as if such successor Person had been named as the Company herein, and thereafter, except in the case of a lease to another Person, the predecessor Person shall be relieved of all obligations and covenants under this Indenture and the Securities.

**ARTICLE V** **<br> DEFAULTS AND REMEDIES**

SECTION 5.01. *Events of Default*. "Event of Default" means any one of the following events (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body):

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) default in the payment of the principal of or premium, if any, on the Securities at Maturity, and continuance of such default for a period of 10 days; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) default in the payment of interest or Additional Amounts, if any, with respect to the Securities when they become due and payable, and continuance of such default for a period of 30 consecutive days; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) default in the observance or performance, or breach, of any covenant of the Company or the Guarantors with respect to the Securities or this Indenture (other than a covenant a default in whose performance or whose breach is elsewhere in this Section 5.01 specifically dealt with), and continuance of such default or breach for a period of 90 days after there has been given, in conformity with Section 11.02, to the Company and the Guarantors by the Trustee or to the Company, the Guarantors and the Trustee by the Holders of at least 25% in aggregate principal amount of the outstanding Securities a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a "Notice of Default" hereunder; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) the entry by a court having jurisdiction in the premises of (A) a decree or order for relief in respect of the Company or a Guarantor in an involuntary case or proceeding under any applicable Bankruptcy Law or (B) a decree or order adjudging the Company or a Guarantor a bankrupt or insolvent, or approving as properly filed a petition seeking reorganization, arrangement, adjustment or composition of or in respect of the Company or a Guarantor under any applicable Bankruptcy Law, or appointing a custodian, receiver, receiver and manager, interim receiver, administrator, monitor, liquidator, assignee, trustee, sequestrator or other similar official of the Company or a Guarantor or of any substantial part of the property of the Company or a Guarantor, or ordering the winding up or liquidation of the affairs of the Company or a Guarantor, and the continuance of any such decree or order for relief or any such other decree or order unstayed and in effect for a period of 90 consecutive days; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(v) the commencement by the Company or a Guarantor of a voluntary case or proceeding under any applicable Bankruptcy Law or of any other case or proceeding to be adjudicated a bankrupt or insolvent, or the consent by either of them to the entry of a decree or order for relief in respect of the Company or a Guarantor in an involuntary case or proceeding under any applicable Bankruptcy Law or to the commencement of any bankruptcy or insolvency case or proceeding against any of them, or the filing by any of them of a petition or answer or consent seeking reorganization or relief under any applicable Bankruptcy Law, or the consent by any of them to the filing of such petition or to the appointment of or taking possession by a custodian, receiver, receiver and manager, interim receiver, administrator, monitor, liquidator, assignee, trustee, sequestrator or similar official of the Company or a Guarantor or of any substantial part of the property of the Company or a Guarantor, or the making by either of them of an assignment for the benefit of creditors, or the admission by either of them in writing of its inability to pay its debts generally as they become due, or the taking of corporate action by the Company or a Guarantor in furtherance of any such action; or

The Trustee shall not be deemed to know of a Default or Event of Default unless a Responsible Officer at the Corporate Trust Office of the Trustee has actual knowledge of such Default or Event of Default with specific reference to such Default, the Securities and this Indenture. No duty imposed upon the Trustee in this Indenture shall be applicable with respect to any Default or Event of Default of which the Trustee is not deemed to have notice. No duty imposed upon the Trustee in this Indenture shall be applicable with respect to any Default or Event of Default of which the Trustee shall not have received notice in accordance with the terms of this Indenture.

When a Default is cured, or when an Event of Default is deemed cured pursuant to Section 5.04, such Default, or Event of Default, as the case may be, ceases.

SECTION 5.02. *Acceleration*. If an Event of Default (other than an Event of Default specified in clause (iv) or (v) of Section 5.01) occurs and is continuing with respect to the Securities, the Trustee by notice to the Company and the Guarantors, or the Holders of at least 25% in aggregate principal amount of the then outstanding Securities by written notice to the Company, the Guarantors and the Trustee, may declare the principal of, premium, if any, Additional Amounts, if any, and accrued and unpaid interest on all then outstanding Securities to be due and payable immediately. Upon any such declaration the amounts due and payable on the Securities, as determined in accordance with the final paragraph of this Section 5.02, shall be due and payable immediately. If an Event of Default specified in clause (iv) or (v) of Section 5.01 occurs, the principal of, premium, if any, Additional Amounts, if any, and interest on all Securities then outstanding shall *ipso facto* become and be immediately due and payable without any declaration, notice or other act on the part of the Trustee or any Holder.

At any time after such an acceleration of the Securities has occurred and before a judgment for payment of the money due has been obtained by the Trustee as hereinafter in this Article V provided, the Holders of a majority in aggregate principal amount of the outstanding Securities, by written notice to the Company, the Guarantors and the Trustee, may rescind and annul such acceleration and its consequences if:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) the Company or the Guarantors have paid or deposited with the Trustee a sum sufficient to pay:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(A) the principal of and premium, if any, on any Securities which have become due otherwise than by such declaration of acceleration and Additional Amounts, if any, and any interest thereon then due at the rate or rates prescribed therefor in such Securities or in this Indenture,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(B) to the extent that payment of such interest is lawful, interest upon overdue interest and overdue Additional Amounts, if any, at the rate or rates prescribed therefor in such Securities or in this Indenture, and

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) all Events of Default, other than the non-payment of the principal of Securities which have become due solely by such declaration of acceleration, have been cured or waived as provided in Section 5.04.

No such rescission shall affect any subsequent Event of Default or impair any right consequent thereon.

If the Maturity of the Securities is accelerated pursuant to this Section 5.02, 100% of the principal amount thereof and premium, if any, shall become due and payable plus Additional Amounts, if any, and accrued and unpaid interest to the date of payment.

SECTION 5.03. *Other Remedies*. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payment of principal of, premium, if any, Additional Amounts, if any, or interest on the Securities or to enforce the performance of any provision of the Securities, the related Guarantees or this Indenture.

The Trustee may maintain a proceeding even if it does not possess any of the Securities or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. All remedies are cumulative to the extent permitted by law.

SECTION 5.04. *Waiver of Existing Defaults*. Subject to Sections 5.07 and 8.02, the Holders of a majority in aggregate principal amount of the Securities then outstanding, by written notice to the Trustee, may waive an existing Default or Event of Default and its consequences (including waivers obtained in connection with a tender offer or exchange offer for such Securities or a solicitation of consents in respect of such Securities; *provided* that in each case such offer or solicitation is made to all Holders of the Securities then outstanding on equal terms), except (1) a continuing Default or Event of Default in the payment of the principal of or premium, if any, Additional Amounts, if any, or interest on the Securities or (2) a continuing Default in respect of a provision that under Section 8.02 cannot be amended without the consent of each Holder affected. Upon any such waiver, such Default shall cease to exist, and any Event of Default arising therefrom shall be deemed to have been cured for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other Default or impair any right consequent thereon.

SECTION 5.05. *Control by Majority*. The Holders of a majority in aggregate principal amount of the Securities then outstanding may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on it hereunder. The Trustee, however, may refuse to follow any direction that conflicts with applicable law or this Indenture that the Trustee determines may be unduly prejudicial to the rights of other Holders (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not any such direction unduly prejudices the rights of such Holders), or that may involve the Trustee in personal liability; *provided*, *however*, that the Trustee may take any other action deemed proper by the Trustee that is not inconsistent with such direction. Prior to taking any action hereunder, the Trustee shall receive indemnification from such Holders satisfactory to it against all losses and expenses caused by taking or not taking such action subject to the Trustee's duty to act with the required standard of care during a default.

SECTION 5.06. *Limitations on Suits*. Subject to Section 5.07, a Holder of Securities may pursue a remedy with respect to this Indenture (including the Guarantees) or the Securities only if:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) such Holder gives to the Trustee written notice of a continuing Event of Default;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) the Holders of at least 25% in aggregate principal amount of the Securities then outstanding make a written request to the Trustee to pursue the remedy;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) such Holder or Holders furnish to the Trustee indemnity and security satisfactory to the Trustee against any loss, liability or expense;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) the Trustee does not comply with the request within 60 days after receipt of the request and the furnishing of such indemnity; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(v) during such 60-day period the Holders of a majority in aggregate principal amount of the Securities then outstanding do not give the Trustee a direction inconsistent with the request.

A Holder may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over another Holder (it being understood that the Trustee does not have an affirmative duty to ascertain whether or not such action or forbearances are unduly prejudicial to such Holders or obtain a preference or priority over another Holder).

SECTION 5.07. *Rights of Holders to Receive Payment*. Notwithstanding any other provision of this Indenture, the right of any Holder of a Security to receive payment of principal of and premium, if any, Additional Amounts, if any, and interest on the Securities, on or after the respective due dates expressed in the Security, or to bring suit against the Company or the Guarantors for the enforcement of any such payment on or after such respective dates, is absolute and unconditional and shall not be impaired or affected without the consent of such Holder or obtain a preference or priority over another Holder.

SECTION 5.08. *Collection Suit by Trustee*. If an Event of Default specified in clause (i) or (ii) of Section 5.01 occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Company and the Guarantors (i) for the amount of principal of and premium, if any, Additional Amounts, if any, and interest remaining unpaid on any Securities and (ii) interest on overdue principal, premium, if any, Additional Amounts, if any, and, to the extent lawful, interest on overdue interest, and such further amount as shall be sufficient to cover the reasonable and documented costs, fees and expenses of collection, including the reasonable and documented compensation, expenses, fees, disbursements and advances of the Trustee, its agents and counsel.

SECTION 5.09. *Trustee May File Proofs of Claim*. The Trustee is authorized to file such proofs of claim and other papers or documents and to take such actions, including participating as a member, voting or otherwise, of any committee of creditors, as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the compensation, reasonable expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders allowed in any judicial proceedings relative to the Company and the Guarantors or their respective creditors or properties and shall be entitled and empowered to collect, receive and distribute any money or other property payable or deliverable on any such claims and any Custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee, and in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the compensation, reasonable expenses, fees, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 6.07. To the extent that the payment of any such compensation, fees, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 6.07 out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties which the Holders of the Securities may be entitled to receive in such proceeding whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

SECTION 5.10. *Priorities*. If the Trustee collects any money pursuant to this Article V, it shall pay out the money in the following order:

First: to the Trustee, its agents and attorneys for amounts due under this Indenture, including payment of all compensation, expenses and liabilities incurred, and all advances made, by the Trustee and the costs, fees and expenses of collection;

Second: to Holders for amounts due and unpaid on the Securities for principal, premium, if any, Additional Amounts, if any, and interest ratably, without preference or priority of any kind, according to the amounts due and payable on the Securities for principal, premium, if any, Additional Amounts, if any, and interest, respectively; and

Third: to the Company and the Guarantors.

The Trustee, upon prior written notice to the Company and the Guarantors, may fix a record date and payment date for any payment to Holders pursuant to this Article V. At least 15 days before such record date, the Trustee shall send to each Holder and the Company a notice that states the record date, the payment date and amount to be paid.

SECTION 5.11. *Undertaking for Costs*. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as a trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys' fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 5.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 5.07, or a suit by a Holder or Holders of more than 10% in aggregate principal amount of the Securities then outstanding.

**ARTICLE VI** **<br> TRUSTEE**

SECTION 6.01. *Duties of Trustee*.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) If an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in such exercise, as a prudent man would exercise or use under the circumstances in the conduct of his own affairs.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Except during the continuance of an Event of Default:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) the duties of the Trustee will be determined solely by the express provisions of this Indenture and the Trustee need perform only those duties that are specifically set forth in this Indenture and no others, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) in the absence of gross negligence on its part, the Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture. However, the Trustee shall examine such certificates and opinions to determine whether or not, on their face, they appear to conform to the requirements of this Indenture (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) The Trustee may not be relieved from liability for its own grossly negligent action, its own grossly negligent failure to act, or its own willful misconduct, except that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) this paragraph does not limit the effect of paragraph (b) of this Section 6.01;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it is proved that the Trustee was grossly negligent in ascertaining the pertinent facts;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) The Trustee shall not be liable for any acts or omissions, except for such losses, damages or expenses which have been finally adjudicated by a court of competent jurisdiction to have directly resulted from the Trustee's gross negligence or willful misconduct; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) the Trustee shall not be liable with respect to any action it takes or omits to take in good faith in accordance with a direction received by it pursuant to Section 5.05 hereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) Whether or not therein expressly so provided, every provision of this Indenture that in any way relates to the Trustee is subject to paragraphs (a), (b) and (c) of this Section 6.01.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) No provision of this Indenture shall require the Trustee to expend or risk its own funds or incur any liability. The Trustee may refuse to perform any duty or exercise any right or power unless it receives indemnity satisfactory to it against any loss, liability or expense.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) The Trustee shall not be liable for interest on any money received by it except as the Trustee may agree in writing with the Company. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) In no event shall the Trustee be responsible or liable for special, indirect, punitive, incidental or consequential loss or damage of any kind whatsoever (including, but not limited to, loss of profit) irrespective of whether the Trustee has been advised of the likelihood of such loss or damage and regardless of the form of action.

SECTION 6.02. *Rights of Trustee*.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The Trustee may rely conclusively on and shall be protected in action or refraining from acting upon any resolution, certificate, statement, direction, consent, order, bond, note or other paper or document believed by it to be genuine and to have been signed or presented by the proper Person. The Trustee need not investigate any fact or matter stated in any such paper or document.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Before the Trustee acts or refrains from acting, it may require an Officer's Certificate or an Opinion of Counsel or both. The Trustee shall not be liable for any action it takes or omits to take in good faith in reliance on such Officer's Certificate or Opinion of Counsel. The Trustee may consult with counsel of its selection and the advice of such counsel or any Opinion of Counsel shall be full and complete authorization and protection in respect of any action taken, suffered or omitted by it hereunder in good faith and in reliance thereon.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) The Trustee may act through agents or attorneys and shall not be responsible for the acts or omissions of any agent or attorney appointed with due care.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) The Trustee shall not be liable for any action it takes or omits to take in good faith which it believes to be authorized or within its rights or powers conferred upon it by this Indenture.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) Unless otherwise specifically provided in this Indenture, any demand, request, direction or notice from the Company or a Guarantor shall be sufficient if signed by an Officer of the Company or such Guarantor, as the case may be.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) No provision of this Indenture will require the Trustee to expend or risk its own funds or incur any liability. The Trustee is under no obligation to exercise any of its rights or powers under this Indenture at the request of any Holders, unless such Holder has offered to the Trustee indemnity or security satisfactory to it against any loss, liability or expense that might be incurred by it in connection with its compliance with such request.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) The Trustee is not required to give any bond or surety with respect to the performance of its duties or the exercise of its powers under this Indenture.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(h) The Trustee shall not be responsible or liable for any action taken or omitted by it in good faith at the direction of the Holders of not less than a majority in principal amount of the Securities as to the time, method and place of conducting any proceedings for any remedy available to the Trustee or the exercising of any power conferred by this Indenture.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) The Trustee's immunities and protections from liability and its right to indemnification in connection with the performance of its duties under this Indenture shall extend and be enforceable by the Trustee in each of its capacities hereunder and shall extend to the Trustee's officers, directors, agents, attorneys and employees. Such immunities and protections and right to indemnity, together with the Trustee's right to compensation, shall survive the Trustee's resignation or removal, the discharge of this Indenture and final payment of the Securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(j) The permissive right of the Trustee to take the actions permitted by this Indenture shall not be construed as an obligation or duty to do so.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(k) Except for information provided by the Trustee concerning the Trustee, the Trustee shall have no responsibility for any information in any disclosure material distributed with respect to the Securities, and the Trustee shall have no responsibility for compliance with any U.S. Federal or State securities or employee benefit plan laws in connection with the Securities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(l) The Trustee may request that the Company or any Guarantor, as the case may be, deliver an Officer's Certificate setting forth the names of individuals and/or titles of officers authorized at such time to take specified actions pursuant to this Indenture, which Officer's Certificate may be signed by any person authorized to sign an Officer's Certificate, including any person specified as so authorized in any such certificate previously delivered and not superseded.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(m) The Trustee undertakes to perform such duties and only such duties as are specifically and expressly set forth in this Indenture. These duties shall be deemed purely ministerial in nature, and the Trustee shall not be liable except for the performance of such duties, and no implied covenants or obligations shall be read into this Agreement against the Trustee.

SECTION 6.03. *Individual Rights of Trustee*. The Trustee in its individual or any other capacity may become the owner or pledgee of Securities and may otherwise deal with the Company, the Guarantors or any of their Affiliates with the same rights it would have if it were not the Trustee. Any Agent may do the same with like rights. However, the Trustee is subject to Sections 6.10 and 6.11.

SECTION 6.04. *Trustee's Disclaimer*. The Trustee makes no representation as to the validity or adequacy of this Indenture, the Securities or the Guarantees, it shall not be accountable for any money paid to the Company or upon the Company's direction under any provision hereof, it shall not be responsible for the use or application of any money received by any Paying Agent other than the Trustee and it shall not be responsible for any statement or recital herein or any statement in the Securities or any other document in connection with the issuance of the Securities or pursuant to this Indenture other than its certificate of authentication.

SECTION 6.05. *Notice of Defaults*. If a Default or Event of Default occurs and is continuing and it is actually known to a Responsible Officer of the Trustee, the Trustee shall send to the Holders of such Securities a notice of such Default or Event of Default within 90 days after it occurs. Except in the case of a Default or Event of Default in payment of principal of or premium, if any, Additional Amounts, if any, or interest on any Security, the Trustee may withhold the notice if and so long as it in good faith determines that withholding the notice is in the interests of Holders.

SECTION 6.06. [*Reserved]*

SECTION 6.07. *Compensation and Indemnity*. The Company and the Guarantors jointly and severally agree to pay to the Trustee such compensation as the Company and the Trustee shall from time to time agree in writing. The Company shall reimburse the Trustee upon request for all reasonable and documented out-of-pocket expenses incurred or made by it, including costs of collection, in addition to the compensation for its services. Such expenses shall include the reasonable compensation and expenses, disbursements and advances of the Trustee's agents and counsel. The Trustee's compensation shall not be limited by any law on compensation of a trustee of an express trust. The Company and the Guarantors jointly and severally agree to reimburse the Trustee upon request for all reasonable and documented disbursements, advances and expenses incurred by it. Such expenses shall include the reasonable compensation, disbursements and expenses of the Trustee's agents and counsel.

The Company and the Guarantors jointly and severally agree to indemnify, defend and protect the Trustee or any predecessor Trustee and their agents, employees, officers and directors for and to hold them harmless against any and all loss, liability, damage, claim, or expense (including reasonable and documented fees and expenses of counsel and taxes, other than taxes based upon, measured by or determined by the income of the Trustee) and court costs incurred by it arising out of or in connection with this Indenture or the administration of this trust, including the reasonable and documented costs and expenses of enforcing this Indenture (including, without limitation, this provision) against the Company and of defending itself against any claim (whether asserted by the Company, the Guarantors, any Holder or any other Person), except as set forth in the next paragraph. The Trustee shall notify the Company and the Guarantors promptly of any claim for which it may seek indemnity; however, failure to give such notice shall not relieve the Company or the Guarantors of their obligations. The Company shall defend the claim and the Trustee shall cooperate in the defense. The Trustee may have separate counsel, and the Company and the Guarantors shall pay the reasonable fees and expenses of such counsel. The Company need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld.

Notwithstanding anything herein to the contrary, neither the Company nor the Guarantors shall be obligated to reimburse any fee or expense or indemnify against any loss, liability, damage, claim or expense incurred by the Trustee through its own gross negligence or willful misconduct (as found by a court of competent jurisdiction in a final, non-appealable judgment).

To secure the payment obligations of the Company and the Guarantors in this Section 6.07, the Trustee shall have a lien prior to the Securities on all money or property held or collected by the Trustee, except that held in trust to pay principal of and premium, if any, and Additional Amounts, if any, and interest on the Securities. Such lien shall survive the satisfaction and discharge of this Indenture.

When the Trustee incurs expenses or renders services after an Event of Default specified in Section 5.01(iv) or (v) occurs, the expenses and the compensation for the services are intended to constitute expenses of administration under any Bankruptcy Law.

SECTION 6.08. *Replacement of Trustee*. A resignation or removal of the Trustee and appointment of a successor Trustee shall become effective only upon the successor Trustee's acceptance of appointment as provided in this Section 6.08.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) the Trustee fails to comply with Section 6.10;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) the Trustee is adjudged a bankrupt or an insolvent or an order for relief is entered with respect to the Trustee under any Bankruptcy Law;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) a Custodian or public officer takes charge of the Trustee or its property; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) the Trustee otherwise becomes incapable of acting.

If the Trustee resigns or is removed or if a vacancy exists in the office of Trustee for any reason, the Company and the Guarantors shall promptly appoint a successor Trustee. Within one year after the successor Trustee takes office, the Holders of a majority in aggregate principal amount of the Securities then outstanding may appoint a successor Trustee to replace the successor Trustee appointed by the Company.

If a successor Trustee does not take office within 30 days after the retiring Trustee resigns or is removed, the retiring Trustee (at the Company's expense), the Company or the Holders of at least 10% in aggregate principal amount of the Securities then outstanding may petition any court of competent jurisdiction at the expense of the Company for the appointment of a successor Trustee.

If the Trustee fails to comply with Section 6.10, any Holder may petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

A successor Trustee shall deliver a written acceptance of its appointment to the retiring Trustee and to the Company and the Guarantors. Thereupon, the resignation or removal of the retiring Trustee shall become effective, and the successor Trustee shall have all the rights, powers and duties of the Trustee under this Indenture. The successor Trustee shall send a notice of its succession to Holders.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(viii) make any change in the percentage of principal amount of the Securities necessary to waive compliance with or to modify certain provisions of this Indenture pursuant to Section 5.04 or 5.07 or this clause of this Section 8.02; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ix) waive a continuing Default or Event of Default in the payment of principal of or premium, if any, Additional Amounts, if any, or interest, including defaulted interest, on the Securities.

The right of any Holder to participate in any consent required or sought pursuant to any provision of this Indenture (and the obligation of the Company 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 the Securities as of a record date fixed by the Company in accordance with Section 8.04 of this Indenture.

SECTION 8.03. [*Reserved*]

SECTION 8.04. *Revocation and Effect of Consents*. A consent to an amendment, a supplement or a waiver by a Holder is a continuing consent by the Holder and every subsequent Holder of a Security or portion of a Security that evidences the same debt as the consenting Holder's Security, even if notation of the consent is not made on any Security. However, any such Holder or subsequent Holder may revoke the consent as to its Security or portion of a Security if the Trustee receives written notice of revocation at any time prior to (but not after) the date the Trustee receives an Officer's Certificate certifying that the Holders of the requisite aggregate principal amount of Securities have consented (and not theretofore revoked such consent) to the amendment, supplement or waiver.

The Company may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to consent to any amendment, supplement or waiver or to take any other action with respect to the Securities under this Indenture. If a record date is fixed, then notwithstanding the provisions of the immediately preceding paragraph, those Persons who were Holders at the close of business on such record date (or their duly designated proxies), and only those Persons, shall be entitled to consent to such amendment, supplement or waiver or to revoke any consent previously given, whether or not such Persons continue to be Holders after such record date, and for this purpose the Securities then outstanding shall be computed as of such record date. No consent shall be valid or effective for more than 90 days after such record date unless consents from Holders of the aggregate principal amount of the Securities required hereunder for such amendment, supplement or waiver to be effective shall have also been given and not revoked within such 90-day period.

After an amendment, supplement or waiver becomes effective, it shall bind every Holder, unless it is of the type described in any of clauses (i) through (viii) of Section 8.02. In such case, the amendment, supplement or waiver shall bind each Holder who has consented to it and every subsequent Holder that evidences the same debt as the consenting Holder's Security.

SECTION 8.05. *Notation on or Exchange of Securities*. If an amendment or supplement changes the terms of a Security, the Trustee may require the Holder of the Security to deliver it to the Trustee. The Trustee may place an appropriate notation on the Security regarding the changed terms and return it to the Holder. Alternatively, if the Company or the Trustee so determines, the Company in exchange for the Security shall issue and the Trustee shall authenticate a new Security that reflects the changed terms. Failure to make the appropriate notation or to issue a new Security shall not affect the validity of such amendment or supplement.

SECTION 8.06. *Trustee to Sign Amendments, etc.*. The Trustee shall sign any supplemental indenture authorized pursuant to this Article VIII if the supplemental indenture does not adversely affect the rights, duties, liabilities or immunities of the Trustee. If it does, the Trustee may, but need not, sign it. In signing or refusing to sign such supplemental indenture, the Trustee shall receive, and subject to Section 6.01, shall be fully protected in conclusively relying upon, an Opinion of Counsel and an Officer's Certificate, as conclusive evidence that all conditions precedent to such supplemental indenture have been complied with, that such supplemental indenture is authorized or permitted by this Indenture, that it is not inconsistent herewith, and that it will be valid and binding upon the Company and the Guarantors in accordance with its terms.

**ARTICLE IX** **<br> GUARANTEES OF SECURITIES**

SECTION 9.01. *Unconditional Guarantees*.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) For value received, each of the Guarantors hereby fully, irrevocably, unconditionally and absolutely guarantees to the Holders and to the Trustee the due and punctual payment of the principal of and premium, if any, Additional Amounts, if any, and interest on the Securities and all other amounts due and payable under this Indenture and the Securities by the Company (including, without limitation, all costs and expenses (including reasonable legal fees and disbursements) incurred by the Trustee or the Holders in connection with the enforcement of this Indenture, the Securities and the Guarantees) (collectively, the "Indenture Obligations"), when and as such principal, premium, if any, Additional Amounts, if any, and interest and such other amounts shall become due and payable, whether at the Stated Maturity, upon redemption or by declaration of acceleration or otherwise, according to the terms of the Securities and this Indenture. The guarantees by the Guarantors set forth in this Article IX are referred to herein as the "Guarantees." Without limiting the generality of the foregoing, each Guarantor's liability shall extend to all amounts that constitute part of the Indenture Obligations and would be owed by the Company under this Indenture and the Securities but for the fact that they are unenforceable, reduced, limited, impaired, suspended or not allowable due to the existence of a bankruptcy, reorganization or similar proceeding involving the Company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Failing payment when due of any amount guaranteed pursuant to the Guarantees, for whatever reason, the Guarantors will be obligated to pay the same immediately to the Trustee, without set-off or counterclaim or other reduction whatsoever (whether for taxes, withholding or otherwise). The Guarantees of the Upper Tier Notes Guarantors and Nabors Bermuda are intended to be general, unsecured, senior obligations of such Guarantors and to rank *pari passu* in right of payment with all indebtedness of such Guarantor that is not, by its terms, expressly subordinated in right of payment to the Guarantees of such Guarantor. The Guarantees of the Lower Tier Notes Guarantors are intended to be unsecured obligations and subordinated in right of payment to guarantees by the Lower Tier Notes Guarantors of Senior Guaranteed Debt, including obligations under the Credit Agreement, pursuant to the terms of the Subordination Agreement. Each Guarantor hereby agrees that its obligations hereunder shall be full, irrevocable, unconditional and absolute, irrespective of the validity, regularity or enforceability of the obligations and liabilities of any other obligor with respect to the Securities, the Guarantees or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder with respect to any provisions hereof or thereof with respect to the same, the recovery of any judgment against the Company, or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of such Guarantor.

Each Guarantor hereby agrees that in the event of a default in payment of the principal of or premium, if any, Additional Amounts, if any, or interest on the Securities or any other amounts payable under this Indenture and such Securities by the Company, whether at the Stated Maturity, upon redemption or by declaration of acceleration or otherwise, legal proceedings may be instituted by the Trustee on behalf of the Holders or, subject to Section 5.06, by the Holders, on the terms and conditions set forth in this Indenture, directly against such Guarantor to enforce the Guarantees without first proceeding against the Company, subject to the provisions of the Subordination Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) To the fullest extent permitted by applicable law, the obligations of each Guarantor under this Article IX shall be as aforesaid full, irrevocable, unconditional and absolute and except as set forth in this Article IX shall not be impaired, modified, discharged, released or limited by any occurrence or condition whatsoever, including, without limitation, (i) any compromise, settlement, release, waiver, renewal, extension, indulgence or modification of, or any change in, any of the obligations and liabilities of any other obligor with respect to the Securities or this Indenture, (ii) any impairment, modification, release or limitation of the liability of the Company, any Guarantor or any of their respective estates in bankruptcy, or any remedy for the enforcement thereof, resulting from the operation of any present or future provision of any applicable Bankruptcy Law, or other statute or from the decision of any court, (iii) the assertion or exercise by the Company, any Guarantor or the Trustee of any rights or remedies under any of the Securities or this Indenture or its delay in or failure to assert or exercise any such rights or remedies, (iv) the assignment or the purported assignment of any property as security for any of the Securities, including all or any part of the rights of the Company or any Guarantor under this Indenture, (v) the extension of the time for payment by the Company or any Guarantor of any payments or other sums or any part thereof owing or payable under any of the terms and provisions of any of the Securities or this Indenture or of the time for performance by the Company or any Guarantor of any other obligations under or arising out of any such terms and provisions or the extension or the renewal of any thereof, (vi) the modification or amendment (whether material or otherwise) of any duty, agreement or obligation set forth in this Indenture of any other obligor with respect to the Securities, (vii) the voluntary or involuntary liquidation, dissolution, sale or other disposition of all or substantially all of the assets, marshaling of assets and liabilities, receivership, insolvency, bankruptcy, assignment for the benefit of creditors, reorganization, arrangement, composition or readjustment of, or other similar proceeding affecting, any of the Company or any Guarantor or any of its assets, or the disaffirmance of any of the Securities, the Guarantees or this Indenture in any such proceeding, (viii) the release or discharge of the Company or any Guarantor from the performance or observance of any agreement, covenant, term or condition contained in any of such instruments by operation of law, (ix) the unenforceability of any of the obligations of any of the other obligors under the Securities, the Guarantees or this Indenture, (x) any change in the name, business, capital structure, corporate existence, or ownership of the Company or any Guarantor, or (xi) any other circumstance which might otherwise constitute a defense available to, or a legal or equitable discharge of, a surety or any Guarantor.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) Each Guarantor hereby (i) waives diligence, presentment, demand of payment, notice of acceptance, filing of claims with a court in the event of the merger, amalgamation, insolvency or bankruptcy of the Company or any Guarantor, and all demands and notices whatsoever, (ii) acknowledges that any agreement, instrument or document evidencing the Guarantees may be transferred and that the benefit of its obligations hereunder shall extend to each holder of any agreement, instrument or document evidencing the Guarantees without notice to them and (iii) covenants that its Guarantees will not be discharged except by complete performance of the Guarantees or of the obligations guaranteed thereby. Each Guarantor further agrees that if at any time all or any part of any payment theretofore applied by any Person to the Guarantees is, or must be, rescinded or returned for any reason whatsoever, including, without limitation, the insolvency, bankruptcy or reorganization of such Guarantor, the Guarantees shall, to the extent that such payment is or must be rescinded or returned, be deemed to have continued in existence notwithstanding such application, and the Guarantees shall continue to be effective or be reinstated, as the case may be, as though such application had not been made.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) Each Guarantor shall be subrogated to all rights of the Holders and the Trustee against the Company in respect of any amounts paid by such Guarantor pursuant to the provisions of this Indenture; *provided*, *however*, that such Guarantor shall not be entitled to enforce or to receive any payments arising out of, or based upon, such right of subrogation with respect to any of the Securities until all of the Securities and the Guarantees thereof shall have been paid in full or discharged.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) No failure to exercise and no delay in exercising, on the part of the Trustee or the Holders, any right, power, privilege or remedy under this Article IX and the Guarantees shall operate as a waiver thereof, nor shall any single or partial exercise of any rights, power, privilege or remedy preclude any other or further exercise thereof, or the exercise of any other rights, powers, privileges or remedies. The rights and remedies herein provided for are cumulative and not exclusive of any rights or remedies provided in law or equity. Nothing contained in this Article IX shall limit the right of the Trustee or the Holders to take any action to accelerate the Maturity of the Securities pursuant to Article V or to pursue any rights or remedies hereunder or under applicable law.

SECTION 9.02. *Execution and Delivery of Notation of Guarantees*. To further evidence the Guarantees, each Guarantor hereby agrees that a notation of such Guarantees may be endorsed on each Security authenticated and delivered by the Trustee and that such notation shall be executed by either manual or facsimile signature of an Officer of such Guarantor.

Each Guarantor hereby agrees that its Guarantees shall remain in full force and effect notwithstanding any failure to endorse on each Security a notation of the Guarantees.

If an Officer of any Guarantor whose signature is on this Indenture or a Security no longer holds that office at the time the Trustee authenticates such Security or at any time thereafter, such Guarantor's guarantee of such Security shall be valid nevertheless.

The delivery of any Security by the Trustee, after the authentication thereof hereunder, shall constitute due delivery of the Guarantees set forth in this Indenture on behalf of the Guarantors.

SECTION 9.03. *Guarantors May Consolidate, etc., on Certain Terms*. (a) A Guarantor may consolidate, merge or enter into a scheme of arrangement qualifying as an amalgamation with any Person or sell, lease, convey, transfer or otherwise dispose of all or substantially all of its assets to any Person and (b) the Capital Stock of a Guarantor may be sold or otherwise disposed of to another Person; *provided*, *however*, that in the case of the consolidation, merger or scheme or arrangement qualifying as an amalgamation or sale, lease, conveyance, transfer or disposal of all or substantially all of the assets of such Guarantor or the sale or other disposition of the Capital Stock of a Guarantor, if such other Person is not the Company or a Guarantor, such Guarantor's obligations under its Guarantee must be expressly assumed by such other Person, except in connection with a transaction in which the Guarantee of such Guarantor would be released as provided in Section 9.05; *provided*, *further*, for the avoidance of doubt, the release provisions in Section 9.05 shall not apply to any such sale, transfer or other disposition described in this Section 9.03 to Nabors Bermuda or any Affiliate of Nabors Bermuda.

SECTION 9.04. *Luxembourg: Guarantee Limitation*. The guarantee granted by any Guarantor which is incorporated and established in the Grand-Duchy of Luxembourg (a "Luxembourg Guaranto**r**") under this Article IX shall be limited at any time to an aggregate amount not exceeding the higher of: 95% of such Luxembourg Guarantor's *capitaux propres* (as referred to in article 34 of the Luxembourg law dated 19 December 2002 on the commercial register and annual accounts, as amended (the "2002 Law"), and as implemented by the Grand-Ducal regulation dated 18 December 2015 setting out the form and the content of the presentation of the balance sheet and profit and loss account (the "Regulation")) determined as at the date on which a demand is made under the guarantee, increased by the amount of any Intra-Group Liabilities; and 95% of such Luxembourg Guarantor's *capitaux propres* (as referred to in article 34 of the 2002 Law) determined as at the date of this Agreement, increased by the amount of any Intra-Group Liabilities. The amount of the *capitaux propres* under this Article IX shall be determined by the Trustee acting in its sole commercially reasonable discretion and shall be adjusted (by derogation to the rules contained in the 2002 Law and the Regulation) to take into account the fair value rather than book value of the assets of such Luxembourg Guarantor.

For the purpose of this Clause, "Intra-Group Liabilities" shall mean any amounts owed by such Luxembourg Guarantor to any other member of the group and that have not been financed (directly or indirectly) by any amounts raised in relation to the Securities. The above limitation shall not apply (a) in respect of any amounts due by a direct or indirect subsidiary of that Luxembourg Guarantor in relation to the Securities and (b) in respect of any amounts due by any person which is not a direct or indirect subsidiary of that Luxembourg Guarantor in relation to the Securities and which have been on-lent to or made available by whatever means, directly or indirectly, to that Luxembourg Guarantor or any of its direct or indirect subsidiaries.

SECTION 9.05. *Releases*.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The Guarantee of a Guarantor (other than, in the case of clause (iv) below, the Guarantee of Nabors Bermuda) will be automatically released with respect to the Securities:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) upon the sale or other disposition (including by way of consolidation, merger or scheme or arrangement qualifying as an amalgamation) of a Guarantor, including the sale or disposition of Capital Stock of a Guarantor, following which such Guarantor is no longer a Subsidiary of Nabors Bermuda,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) the sale or disposition of all or substantially all the assets (including by way of consolidation, merger or scheme or arrangement qualifying as an amalgamation) of a Guarantor,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) if the Company exercises its legal defeasance option or its covenant defeasance option with respect to the Securities or if the Company's obligations under this Indenture are satisfied and discharged in accordance with Article VII with respect to the Securities; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) if the Securities are rated Investment Grade by at least two of the three Rating Agencies and no Default or Event of Default has occurred and is continuing under this Indenture;

*provided*, *however*, that in the case of clauses (i) and (ii) above, such sale or other disposition is made to a Person other than Nabors Bermuda or one of its Affiliates and such sale or disposition is otherwise permitted by this Indenture.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) At the request of the Company and upon delivery of an Officer's Certificate and Opinion of Counsel, the Trustee shall execute and deliver an appropriate instrument evidencing the release of a Guarantor pursuant to this Section 9.05.

SECTION 9.06. *Subordination Agreement*. On the Issue Date, the Trustee will enter into (by way of joinder) the Subordination Agreement with respect to the Securities. In the event of (i) any amendment, supplement, modification, extension, renewal, restatement or refunding of Senior Guaranteed Debt, (ii) the replacement, refunding or refinancing of any Senior Guaranteed Debt with new Senior Guaranteed Debt or (iii) the Lower Tier Note Guarantors issue new Senior Guaranteed Debt, the Lower Tier Note Guarantors and the Trustee will enter into a subordination agreement substantially consistent with the Subordination Agreement, and the Trustee shall be provided with, and may conclusively rely upon, an Officer's Certificate stating such subordination agreement is permitted by this Indenture and is substantially consistent with the Subordination Agreement with respect to entry into such subordination agreement.

**ARTICLE X** **<br> REDEMPTION**

SECTION 10.01. *Notices to Trustee*. If the Company elects to redeem the Securities pursuant to the redemption provisions of Section 10.07, it shall furnish to the Trustee, at least five days before notice of such redemption is to be given pursuant to Section 10.03 (unless a shorter period is acceptable to the Trustee), an Officer's Certificate setting forth the Redemption Date, the principal amount of such Securities to be redeemed, the redemption price (or the method of calculating the redemption price) and, if the redemption of such Securities is subject to any condition precedent, each such condition precedent.

SECTION 10.02. *Selection of Securities to be Redeemed*. If less than all of the Securities are to be redeemed, the Trustee shall select the Securities to be redeemed on a pro rata basis (or, in the case of Securities represented by a Global Security, in accordance with the Applicable Procedures).

Securities and portions of them selected shall be in minimum amounts of $2,000 and integral multiples of $1,000 in excess thereof. Except as provided in the preceding sentence, provisions of this Indenture that apply to Securities called for redemption also apply to portions of Securities called for redemption.

SECTION 10.03. *Notices to Holders*.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) At least 10 days, but not more than 75 days before a Redemption Date, the Company shall give in conformity with Section 11.02 a notice of redemption to each Holder of Securities to be redeemed. The notice shall identify the Securities to be redeemed (including CUSIP, ISIN or similar numbers, if any) and shall state:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) the Redemption Date;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) the redemption price (or the method of calculating the redemption price);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) if any Security is being redeemed in part, the portion of the principal amount of such Security to be redeemed and that, after the Redemption Date, upon surrender of such Security, a new Security or Securities in principal amount equal to the unredeemed portion will be issued;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) the name and address of the Paying Agent;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(v) that Securities called for redemption must be surrendered to the Paying Agent at the address specified in such notice to collect the redemption price;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vi) that unless the Company defaults in making the redemption payment, interest on Securities called for redemption ceases to accrue on and after the Redemption Date and the only remaining right of the Holders is to receive payment of the redemption price upon surrender to the Paying Agent of the Securities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(vii) the paragraph of the Securities and/or Section of this Indenture pursuant to which the Securities are being redeemed;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(viii) that no representation is made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Securities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ix) the aggregate principal amount of Securities being redeemed; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(x) any condition precedent to such redemption.

If any of the Securities to be redeemed is in the form of a Global Security, then the Company shall modify such notice to the extent necessary to accord with the procedures of the Depositary applicable to redemptions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) At the Company's request, the Trustee shall give the notice required in Section 10.03(a) in the Company's name; *provided*, *however*, that the Company shall deliver to the Trustee, at least 15 days prior to the requested delivery date (unless the Trustee consents in writing to a shorter period), an Officer's Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in Section 10.03(a).

SECTION 10.04. *Effect of Notices of Redemption*. Notice of redemption may be given and any redemption of Securities may, at the Company's discretion, be subject to one or more conditions precedent, including the consummation of a financing transaction or equity issuance, the proceeds of which are to be used to fund such redemption; *provided* that, if notice of redemption is given pursuant to Section 10.03, and such notice does not include a condition precedent to be satisfied in order for the Company to be obligated to redeem the Securities, the Securities called for redemption shall become due and payable on the Redemption Date at the redemption price. Upon surrender to the Paying Agent of Securities called for redemption, such Securities shall be paid out at the redemption price, plus accrued and unpaid interest up to, but excluding, the Redemption Date; *provided*, *however*, that if the Redemption Date is after the taking of a record of the Holders on a record date and on or prior to the related Interest Payment Date, the accrued and unpaid interest shall be payable to the Person in whose name the redeemed Securities are registered on such record date. Failure to give notice or any defect in the notice to any Holder shall not affect the validity of the notice to any other Holder.

SECTION 10.05. *Deposit of Redemption Price*. At or prior to 11:00 a.m. New York City time on the Redemption Date, the Company shall deposit with the Trustee or with the Paying Agent immediately available funds sufficient to pay the redemption price of all Securities to be redeemed on that date, plus accrued and unpaid interest thereon up to, but excluding, the Redemption Date. The Trustee or the Paying Agent shall return to the Company any money not required for that purpose less the expenses of the Trustee as provided herein.

If the Company complies with the preceding paragraph, interest on the Securities or portions thereof to be redeemed (whether or not such Securities are presented for payment) will cease to accrue on the applicable Redemption Date. If any Security called for redemption shall not be so paid upon surrender because of the failure of the Company to comply with the preceding paragraph, then interest will be paid on the unpaid principal, premium, if any, and Additional Amounts, if any, from the Redemption Date until such principal, premium, if any, and Additional Amounts, if any, are paid and, to the extent lawful, on any interest not paid on such unpaid principal, in each case at the rate provided in the Securities and in Section 3.01.

SECTION 10.06. *Securities Redeemed in Part*. Upon surrender of a Security that is redeemed in part, the Company shall issue and the Trustee shall authenticate for the Holder, at the expense of the Company, a new Security equal in principal amount to the unredeemed portion of the Security surrendered.

SECTION 10.07. *Optional Redemption*.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) On or after November 15, 2028, the Company may redeem the Securities, in whole at any time or in part from time to time, at the redemption prices (expressed as a percentage of principal amount of the Securities to be redeemed) set forth below, plus accrued and unpaid interest, if any, on the Securities, to, but excluding, the applicable Redemption Date, if redeemed during the twelve-month period beginning on November 15 of the years indicated below:

---

| | |
|:---|:---|
| Year | Percentage |
| 2028 | 103.813% |
| 2029 | 101.906% |
| 2030 and thereafter | 100.000% |

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) At any time and from time to time prior to November 15, 2028, upon giving notice as provided in Section 10.03 of this Indenture, the Company may redeem up to 35% of the aggregate principal amount of the Securities with an aggregate amount less than or equal to the cash proceeds less any underwriting spread paid in cash of one or more Equity Offerings, at a redemption price equal to 107.625% of the principal amount thereof, plus accrued and unpaid interest, if any, to (but not including) the Redemption Date; *provided*, *however*, that, at least 50% of the original aggregate principal amount of the Securities (excluding any Additional Securities of such series) must remain outstanding immediately after each such redemption; *provided*, *further*, that such redemption shall occur within 180 days after the date on which any such Equity Offering is consummated.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) At any time prior to November 15, 2028, the Company may redeem the Securities, in whole at any time and in part from time to time, upon giving notice as provided in Section 10.03 of this Indenture, at a redemption price equal to 100% of the aggregate principal amount of the Securities to be redeemed, plus the Applicable Premium, plus accrued and unpaid interest, if any, to, but excluding, the Redemption Date.

Notice of any redemption may be given and any redemption of Securities may, at the Company's discretion, be subject to one or more conditions precedent and any redemption pursuant to this Section 10.07 shall be made, to the extent applicable, pursuant to the provisions of Sections 10.01 through 10.06.

SECTION 10.08. *Tax Redemption*.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) The Securities will be subject to redemption by the Company, in whole but not in part, at a redemption price equal to 100% of the outstanding principal amount of the Securities, plus accrued and unpaid interest thereon to, but excluding, the applicable Redemption Date (including any Additional Amounts) at any time prior to their maturity if, due to a Change in Tax Law (as defined below):

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) the Company or a Guarantor in accordance with the terms of the Securities or a Guarantee has, or would, become obligated to pay, on the next date on which any amount would be payable with respect to the Securities or a Guarantee, any Additional Amounts to the Holders of the Securities; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) such obligation cannot be avoided by such Guarantor or the Company taking reasonable measures available to it (including, in the case of a payment by a Guarantor, taking reasonable measures to have the Company or another Guarantor make the relevant payment if this would avoid the obligation to pay Additional Amounts).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) In such case, the Company may redeem the Securities upon not less than 10 days nor more than 75 days' notice provided, that, (i) no such notice of redemption shall be given earlier than 90 days prior to the earliest date on which the Company or such Guarantor, as the case may be, would be obligated to pay any such Additional Amounts in respect of the Securities or applicable Guarantee and (ii) at the time such notice is given, such obligation to pay such Additional Amounts remains in effect. The Company's right to redeem the Securities pursuant to this Section 10.08 shall continue as long as the Company or a Guarantor is obligated to pay such Additional Amounts, notwithstanding that the Company or such Guarantor, as the case may be, shall have made payments of Additional Amounts. Prior to the giving of any such notice of redemption, the Company must deliver to the Trustee: (1) an Officer's Certificate stating that the Company is entitled to effect such redemption and setting forth a statement of facts showing that the conditions precedent to the right of the Company so to redeem have occurred; and (2) an Opinion of Counsel or an independent accountant of recognized standing, selected by the Company or any Guarantor, as applicable, with respect to tax matters of the applicable Relevant Taxing Jurisdiction to the effect that the Company or such Guarantor has, or would, become obligated to pay such Additional Amounts as a result of such Change in Tax Law and the Trustee shall be entitled to accept such Officer's Certificate and Opinion of Counsel as sufficient evidence of the satisfaction of the conditions precedent in which event they shall be conclusive and binding on the holders of the Securities. For the purposes of this Section 10.08, "Change in Tax Law" shall mean any changes in, or amendment to, any law of a Relevant Taxing Jurisdiction (including any regulations or rulings promulgated thereunder and including, for this purpose, any treaty entered into by the Relevant Taxing Jurisdiction) or any amendment to or change in the application or official interpretation (including judicial or administrative interpretation) of such law, which change or amendment becomes effective or, in the case of an official interpretation, is announced, on or after the date of this Indenture (or, if later, on or after the date on which such Relevant Taxing Jurisdiction became a Relevant Taxing Jurisdiction).

Any redemption pursuant to this Section 10.08 shall be made, to the extent applicable, pursuant to the provisions of Sections 10.01 through 10.06.

The foregoing provisions will apply mutatis mutandis to any successor person, after such successor person becomes a party to this Indenture, with respect to a Change in Tax Law occurring after the time such successor person becomes a party to this Indenture.

**7.625% SENIOR PRIORITY GUARANTEED NOTE DUE 2032**

This Security is one of a duly authorized issue of 7.625% Senior Priority Guaranteed Notes due 2032 (the "Securities") of Nabors Industries, Inc., a Delaware corporation (the "Company").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. *Interest*. The Company promises to pay interest on the principal amount of this Security at a rate of 7.625% per annum until Maturity. The Company will pay interest semi-annually on May 15 and November 15 of each year (each an "Interest Payment Date"), beginning [ ], or if any such day is not a Business Day, on the next succeeding Business Day. Interest on this Security will accrue from the most recent Interest Payment Date on which interest has been paid or, if no interest has been paid, from [ ]; *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. Further, to the extent lawful, the Company shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal, premium, if any, Additional Amounts, if any, and interest (without regard to any applicable grace period), from time to time on demand at the rate then in effect on the Securities. Interest will be computed on the basis of a 360-day year of twelve 30-day months.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. *Method of Payment*. The Company will pay interest on this Security (except defaulted interest) to the Persons who are registered Holders of this Security at the close of business on the record date next preceding the Interest Payment Date, even if this Security is 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 payments of principal and premium, if any. The Company will pay the principal of and premium, if any, and Additional Amounts, if any, and interest on this Security in money of the United States of America that at the time of payment is legal tender for payment of public and private debts. Payments in respect of the Securities represented by a Global Security (including principal, premium, if any, Additional Amounts, if any, and interest) will be made by wire transfer of immediately available funds to the accounts specified by The Depository Trust Company. The Company will make all payments in respect of a certificated Security (including principal, premium, if any, Additional Amounts, if any, and interest) at the office or agency of the Paying Agent maintained for such purpose or, at its option, by mailing a check to the registered address of each Holder thereof; *provided*, *however*, that payments on a certificated Security will be made by wire transfer to a U.S. dollar account maintained by the payee with a bank in the United States if such Holder elects payment by wire transfer by giving written notice to the Trustee or the Paying Agent to such effect designating such account no later than 30 days immediately preceding the relevant due date for payment (or such other date as the Trustee may accept in its discretion).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. *Ranking and Guarantees*. This Security is a senior unsecured obligation of the Company and is guaranteed pursuant to guarantees (the "Guarantees") by the Guarantors to the extent set forth in the Indenture. The Guarantees are senior unsecured obligations of the Guarantors, except that certain of the Guarantees are subject to the Subordination Agreement described in the Indenture. References herein to the Indenture or the Securities shall be deemed also to refer to the Guarantees set forth in the Indenture except where the context otherwise requires.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. *Optional Redemption; Purchases upon Change of Control Triggering Event*.

The Securities are subject to the optional redemption provisions set forth in Sections 10.07 and 10.08 of the Indenture and certain offers to repurchase upon the occurrence of certain Change of Control Triggering Events as set forth in Section 3.10 of the Indenture.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5. *Paying Agent and Registrar*. Initially, Wilmington Trust, National Association., the Trustee under the Indenture, will act as Paying Agent and Registrar.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6. *Indenture*. The Company issued this Security under an Indenture dated as of November 10, 2025 (as amended, supplemented or otherwise modified from time to time, the "Indenture") among the Company, the Guarantors and Wilmington Trust, National Association, (the "Trustee"). The terms of this Security include those stated in the Indenture. This Security and the Guarantees are subject to all such terms, and Holders are referred to the Indenture for a statement of such terms. To the extent any provision of this Security conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling (to the extent permitted by law). The Securities are unsecured obligations of the Company. The Company initially has issued $700,000,000 aggregate principal amount of Securities. The Company may issue Additional Securities of the same series as this Security under the Indenture, *provided* that a separate CUSIP will be used for any Additional Securities that are not "fungible" for U.S. federal income tax purposes with the Securities issued on the date of the Indenture. Capitalized terms used but not defined in this Security have the respective meanings given to such terms in the Indenture.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7. *Denominations, Transfer, Exchange*. The Securities are issuable only in registered form without coupons in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. The transfer of this Security may be registered and this Security may be exchanged only 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 transfer tax or similar governmental charge or other fee required by law and payable in connection therewith. The Registrar need not exchange or register the transfer of this Security during the period between a record date and the corresponding Interest Payment Date.

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

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;9. *Amendments and Waivers*. The Securities are subject to the amendment and waiver provisions set forth in Article VIII of the Indenture.

Pursuant to the Credit Agreement, dated as of January 21, 2022 (as amended, amended and restated, supplemented or otherwise modified from time to time, the "**Credit Agreement**"), by and among Holdings, the Borrower, the Specified Subsidiary Guarantors, as "Guarantors" and the other subsidiaries of the Borrower from time to time party thereto, as "Guarantors", the lenders and issuing banks from time to time party thereto and the Agent, among other things, (i) the lenders and issuing banks have provided commitments to make loans and provide other accommodations to the Borrower and its subsidiaries and (ii) the Specified Subsidiary Guarantors have provided an unconditional guarantee in full of the Senior Obligations (as defined below).

Accordingly, the Agent, on behalf of itself, the Lenders and Issuing Banks and any other holder of Obligations (the "**Senior Parties**"), the Obligors and each Trustee, on behalf of itself, the holders of the applicable Notes and any other holder of Subordinated Obligations (together with their respective successors and assigns, collectively, the "**Subordinated Parties**"), hereby agree as follows:

SECTION 1. <u>Subordination</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Each Trustee on behalf of itself and the other Subordinated Parties hereby agrees that the Subordinated Obligations shall be subordinate and junior in right of payment to the (i) Obligations of each Specified Subsidiary Guarantor (whether now existing or from time to time after the date hereof incurred, assumed, created or arising) and (ii) Permitted Guaranteed Bilateral Letter of Credit Facilities with a Lender or an affiliate thereof (whether now existing or from time to time after the date hereof incurred, assumed, created or arising), including the payment of principal, premium (if any), interest (including, without limitation, interest accruing on or after the filing of any Insolvency Proceeding, whether or not a claim for post-filing interest is allowed or allowable in any such Insolvency Proceeding), fees, charges, expenses, indemnities, reimbursement obligations and all other amounts payable thereunder or in respect thereof, in each case whether or not any of the foregoing is allowed or allowable as a claim in any Insolvency Proceeding (collectively, the "**Senior Obligations**"). For purposes hereof, "**Subordinated Obligations**" means all obligations of the Specified Subsidiary Guarantors to the Subordinated Parties (whether now existing or from time to time after the date hereof incurred, assumed, created or arising) under each Indenture, including each Subsidiary Notes Guarantee, including, in each case to the extent constituting obligations thereunder, the payment of principal, premium (if any), interest (including, without limitation, interest accruing on or after the filing of any Insolvency Proceeding pursuant to the terms of the Indenture, whether or not a claim for post-filing interest is allowed or allowable in any such Insolvency Proceeding), fees, charges, expenses, indemnities, reimbursement obligations and all other amounts payable thereunder or in respect thereof, in each case whether or not any of the foregoing is allowed or allowable as a claim in any Insolvency Proceeding. For purposes hereof, "**Discharge of the Senior Obligations**" shall mean that the Senior Obligations have been indefeasibly paid in full in cash and all commitments of the Senior Parties under the Loan Documents have been terminated (other than any inchoate obligations for which no claim has been asserted).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**(b)** The Obligors, each Trustee and the other Subordinated Parties agree that no payment (whether directly, by purchase, redemption or exercise of any right of setoff or otherwise) in respect of the Subordinated Obligations, whether as principal, interest or otherwise, and whether in cash, securities or other property, shall be made by or on behalf of any Specified Subsidiary Guarantor or received, accepted or demanded from or on behalf of any Specified Subsidiary Guarantor, directly or indirectly, by or on behalf of any Subordinated Party (other than a payment or distribution in the form of debt or equity securities that are subordinated to the Senior Obligations at least to the same extent as the Subordinated Obligations ("**Permitted Junior Securities**")), until Discharge of the Senior Obligations. In the event that any payment by, or on behalf of, or distribution of the assets or other property of, or any equity securities or debt securities issued by, any Specified Subsidiary Guarantor of any kind or character, whether in cash, securities or other property, and whether directly, by purchase, redemption, exercise of any right of setoff or otherwise (other than a payment or distribution in the form of Permitted Junior Securities), including without limitation, in connection with a plan of reorganization or other Insolvency Proceeding with respect to such Specified Subsidiary Guarantor, shall be received by or on behalf of any Subordinated Party or any Affiliate thereof at a time when such payment or distribution is prohibited by this Agreement, such payment or distribution shall be held by any Subordinated Party or its Affiliate in trust (segregated from other property of any Subordinated Party or its Affiliate) for the benefit of, and shall forthwith be paid over to, the Agent, for the benefit of the Senior Parties, until the Discharge of the Senior Obligations. For the avoidance of doubt, the foregoing does not limit the ability of Holdings to make payments of principal, premium (if any), interest, fees, charges, expenses, indemnities, reimbursement obligations and other amounts payable in respect of the Subordinated Obligations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) The provisions of this Agreement shall continue in full force and effect notwithstanding the occurrence of an Insolvency Proceeding (as defined below) against any Obligor or any of its properties or assets until the Discharge of the Senior Obligations. Upon any distribution of the assets of a Specified Subsidiary Guarantor or upon any dissolution, winding up, liquidation or reorganization of such Specified Subsidiary Guarantor, whether in bankruptcy, insolvency, reorganization, arrangement or receivership proceedings or otherwise, or upon any assignment for the benefit of creditors or any other marshalling of the assets and liabilities of such Specified Subsidiary Guarantor, or otherwise (any of the foregoing, an "**Insolvency Proceeding**"):

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) the Senior Parties shall first be entitled to Discharge of the Senior Obligations before the Subordinated Parties shall be entitled to receive any payment or distribution on account of the Subordinated Obligations, whether of principal, interest or otherwise; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) any payment by, or on behalf of, or distribution of the assets of, or any debt or equity securities issued by, such Specified Subsidiary Guarantor of any kind or character, whether in cash, securities or other property, to which any Subordinated Party would be entitled except for the provisions of this **Section 1** shall be paid or delivered by the Person making such payment or distribution (whether a trustee in bankruptcy, a receiver, custodian or liquidating trustee or otherwise) directly to the Agent, for the benefit of the Senior Parties, until Discharge of the Senior Obligations.

In addition, each Trustee, agrees that in connection with any Insolvency Proceeding (i) the Agent, on behalf of the Senior Parties, is irrevocably authorized and empowered (in its own name or in the name of the Subordinated Parties or otherwise), but shall have no obligation, to demand, sue for, collect and receive every payment or distribution referred to in the preceding sentence and give acquittance therefor and to file claims and proofs of claim and take such other action as the Agent may deem necessary or advisable for the exercise or enforcement of any of the rights or interest of the Senior Parties and (ii) each Subordinated Party shall duly and promptly take such action as the Agent, on behalf of the Senior Parties, may request to (A) collect amounts in respect of the applicable Subordinated Obligations for the account of the Senior Parties and to file appropriate claims or proofs of claim in respect of such Subordinated Obligations, (B) execute and deliver to the Agent such irrevocable powers of attorney, assignments or other instruments as the Agent, on behalf of the Senior Parties, may request in order to enable the Agent to enforce any and all claims with respect to the Subordinated Obligations and (C) collect and receive any and all payments or distributions which may be payable or deliverable upon or with respect to the applicable Subordinated Obligations. A copy of this Agreement may be filed with any court as evidence of the Senior Parties' right, power and authority hereunder.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) The Obligors and each Subordinated Party agree that, prior to the Discharge of the Senior Obligations, no Subordinated Party may take any Enforcement Action against any Specified Subsidiary Guarantor without the prior written consent of the Agent (acting upon the direction ofthe Required Lenders), unless:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) the occurrence of, with respect to such Specified Subsidiary Guarantor, an Insolvency Proceeding;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) the holders of Senior Obligations have taken any Enforcement Action in relation to such Specified Subsidiary Guarantor; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) an event of default has occurred under the applicable Indenture in respect of the applicable Subordinated Obligations (a "**Subordinated Debt Default**"); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(A) the applicable Subordinated Parties have provided notice of the Subordinated Debt Default to the Senior Parties in accordance with

**Section 11** hereof;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(B) a period of not less than (i) 90 days (in the case of a payment default) or (ii) or 179 days (in the case of a non-payment default) has passed from the date the Agent and the Senior Parties were first notified of the Subordinated Debt Default (a "**Standstill Period**"); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(C) at the end of the Standstill Period, the Subordinated Debt Default is continuing and has not been cured or waived.

For the purposes hereof, "**Enforcement Action**" means, in relation to or with respect to any Specified Subsidiary Guarantor, any action (whether taken by the relevant creditor or creditors or an agent or trustee on its or their behalf) to: (i) demand payment, declare prematurely due and payable or otherwise seek to accelerate payment of all or any part of the Subordinated Obligations,

(ii) recover all or any part of the Subordinated Obligations (including, by exercising any rights of set-off or combination of accounts), (iii) exercise or enforce any rights under or pursuant to the Subsidiary Notes Guarantee, (iv) commence legal proceedings against such Specified Subsidiary Guarantor or (v) commence, or take any other steps which could lead to the commencement of, an Insolvency Proceeding concerning such Specified Subsidiary Guarantor. Notwithstanding the foregoing, no Subordinated Party may in any Insolvency Proceeding concerning any Specified Subsidiary Guarantor: (i) oppose any sale of assets (including bidding procedures relating thereto) with respect to such Specified Subsidiary Guarantor; (ii) propose any debtor in possession financing or oppose any debtor in possession financing or use of cash collateral with respect to such Specified Subsidiary Guarantor, in each case without the consent of the Agent, acting on behalf of the Senior Parties; (iii) seek appointment of a trustee or examiner with respect to such Specified Subsidiary Guarantor; or (iv) propose, sponsor, vote in favor of, or otherwise support any plan of reorganization or liquidation with respect to such Specified Subsidiary Guarantor unless such plan (a) provides for Discharge of the Senior Obligations on or before the effective date of such plan or (b) the Agent, on behalf of the Senior Parties has provided its prior written consent with respect to such plan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(e) Each Trustee and the other Subordinated Parties waive all rights of subrogation they may have with respect to any Specified Subsidiary Guarantor under the Subordinated Guaranty until the Discharge of the Senior Obligations, and, as between and among such Specified Subsidiary Guarantor, its creditors (other than the Senior Parties) and the Subordinated Parties, no such payment or distribution made to the Senior Parties by virtue of this Agreement that otherwise would have been made to the Subordinated Parties shall be deemed to be a payment by such Specified Subsidiary Guarantor on account of the Subordinated Obligations, it being understood that the provisions of this **paragraph (e)** are intended solely for the purpose of defining the relative rights of the Subordinated Parties and the Senior Parties.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(f) Each Subordinated Party and Specified Subsidiary Guarantor agrees that each Indenture and all other instruments (including the Notes) or records (other than book entry records) now or hereafter creating or evidencing the Subordinated Obligations, whether upon refunding, extension, renewal, refinancing, replacement or otherwise, shall contain the following language:

"Notwithstanding anything contained herein to the contrary, none of the indebtedness created or evidenced by this instrument or record shall become due or be paid or payable by any Specified Subsidiary Guarantor, except to the extent permitted under the Subordination Agreement dated as of January 21, 2022, among Nabors Industries, Inc., a Delaware corporation, Nabors Industries Ltd., a Bermuda exempted company, the Specified Subsidiary Guarantors, the Trustee, and Citibank, N.A, as administrative agent under the 2022 Revolving Credit Facility<sup>1</sup>, which is attached as Exhibit D to the Indenture, which Subordination Agreement is incorporated herein with the same effect as if fully set forth herein";

or shall otherwise refer to and be subject in all respects to the terms of this Agreement in a manner acceptable to the Agent.

<sup>1</sup> Term to be updated to reference the appropriate defined term in future Indentures and instruments.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(g) For the avoidance of doubt, nothing in this Agreement shall affect the rights of payment relative among the Initial Notes and any Additional Notes which shall rank of equal priority in payment as to each other, unless otherwise expressly agreed by the applicable holders thereof.

SECTION 2. <u>Waivers and Consents</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) Each Trustee and the other Subordinated Parties waive the right to compel that any assets or property of any Specified Subsidiary Guarantor be applied in any particular order to discharge the Senior Obligations. Each Trustee and the other Subordinated Parties expressly waive the right to require the Senior Parties to proceed against any Specified Subsidiary Guarantor, or to pursue any other remedy in any Senior Party's power which the Subordinated Parties cannot pursue and which would lighten the Subordinated Parties' burden, notwithstanding that the failureof any Senior Party to do so may thereby prejudice each Subordinated Party. Each Trustee and theother Subordinated Parties agree that they shall not be discharged, exonerated or have their respective obligations hereunder to the Senior Parties reduced by any Senior Party's delay in proceeding against or enforcing any remedy against any Specified Subsidiary Guarantor; by any Senior Party releasing any Specified Subsidiary Guarantor from all or any part of the Senior Obligations; or by the discharge of any Specified Subsidiary Guarantor by operation of law or otherwise, with or without the intervention or omission of a Senior Party. Any Senior Party's vote to accept or reject any plan of reorganization relating to any Specified Subsidiary Guarantor, or any Senior Party's receipt on account of the Senior Obligations other than Discharge of Senior Obligations, shall not discharge, exonerate, or reduce the obligations of any Subordinated Party hereunder to the Senior Parties.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Each Trustee and the other Subordinated Parties waive all rights and defenses arising out of an election of remedies by the Senior Parties, even though that election of remedies, including any nonjudicial foreclosure with respect to security for the Senior Obligations, has impaired the value of each Subordinated Party's rights of subrogation, reimbursement or contribution against any Specified Subsidiary Guarantor. Each Subordinated Party expressly waives any rights or defenses it may have by reason of protection afforded to any Specified Subsidiary Guarantor with respect to the Senior Obligations pursuant to any anti-deficiency laws or other laws of similar import which limit or discharge the principal debtor's indebtedness upon judicial or nonjudicial foreclosure of real property or personal property securing the Senior Obligations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) Each Trustee and the other Subordinated Parties agree that, without the necessity of any reservation of rights against any of them, and without notice to or further assent by any of them, any demand for payment of any Senior Obligations made by a Senior Party may be rescinded in whole or in part by any Senior Party, and any Senior Obligation may be continued, and the Senior Obligations, or the liability of any Specified Subsidiary Guarantor or any other guarantor or any other party upon or for any part thereof or right of offset with respect thereto, may, from time to time, in whole or in part, be renewed, extended, modified, accelerated, compromised, waived, surrendered, or released by the Senior Parties, in each case without notice to or further assent by any Subordinated Party (to the extent contemplated by the Indenture), which will remain bound under this Agreement and without impairing, abridging, releasing or affecting the subordination and other agreements provided for herein.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) Each Trustee and the other Subordinated Parties waive any and all notice of the creation, renewal, extension or accrual of any of the Senior Obligations and notice of or proof of reliance by the Senior Parties upon this Agreement. The Senior Obligations, and any of them, shall be deemed conclusively to have been created, contracted or incurred and the consent given to create the obligations of the Specified Subsidiary Guarantors in respect of the Subordinated Obligations in reliance upon this Agreement, and all dealings between the Specified Subsidiary Guarantors and the Senior Parties shall be deemed to have been consummated in reliance upon this Agreement. Each Subordinated Party acknowledges and agrees that the Senior Parties have relied upon the subordination and other agreements provided for herein in consenting to the Subordinated Obligations. Each Subordinated Party waives notice of or proof of reliance on this Agreement and protest, demand for payment and notice of default.

SECTION 3. <u>Senior Obligations Unconditional</u>. All rights and interests of the Senior Parties hereunder, and all agreements and obligations of each Subordinated Party and each Specified Subsidiary Guarantor hereunder, shall remain in full force and effect irrespective of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) any lack of validity or enforceability of any of the Loan Documents;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) any change in the time, manner or place of payment of, or in any other term of, all or any of the Senior Obligations, or any amendment or waiver or other modification, whether by course of conduct or otherwise, of, or consent to departure from, any of the Loan Documents; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) any other circumstances that might otherwise constitute a defense available to, or a discharge of, any Specified Subsidiary Guarantor in respect of the Senior Obligations, or of each Subordinated Party or any Specified Subsidiary Guarantor in respect of this Agreement.

SECTION 4. <u>Representations and Warranties</u>. Each Trustee represents and warrants to the Agent, for the benefit of the Senior Parties, that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) It has the power and authority to execute and deliver and to perform its obligations under this Agreement and has taken all necessary action to authorize its execution, delivery and performance of this Agreement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) This Agreement has been duly executed and delivered by such Trustee and constitutes a legal, valid and binding obligation of each Subordinated Party, enforceable against each in accordance with its terms, subject to applicable bankruptcy, insolvency, reorganization, moratorium or other laws affecting creditors' rights generally and subject to general principles of equity, regardless of whether considered in a proceeding in equity or at law.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) No consent or authorization of filing with, or other act by or in respect of, any Governmental Authority, is required in connection with the execution, delivery or performance of this Agreement.

SECTION 5. <u>Waiver of Claims</u>.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) To the maximum extent permitted by law, each Subordinated Party waives any claim it might have against the Senior Parties with respect to, or arising out of, any action or failure to act or any error of judgment, negligence, or mistake or oversight whatsoever on the part of the Senior Parties or their directors, officers, employees, agents or Affiliates with respect to any exercise of rights or remedies under Credit Agreement or the other Loan Documents. Neither the Senior Parties nor any of their respective directors, officers, employees, agents or Affiliates shall be liable for failure to demand, collect or realize upon guarantee of the Senior Obligations by Specified Subsidiary Guarantors or for any delay in doing so.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) Each Trustee and the other Subordinated Parties, each for itself and on behalf of its successors and assigns, respectively, hereby waive any and all now existing or hereafter arising rights it may have to require the Senior Parties to marshal assets for the benefit of each other Subordinated Party, or to otherwise direct the timing, order or manner of any sale, collection or other enforcement of the Senior Obligations. The Senior Parties are under no duty or obligation, and each Trustee and the other Subordinated Parties hereby waive any right it may have to compel the Senior Parties, to pursue any Obligor or other Person who may be liable for the SeniorObligations.

Each Subordinated Party and Specified Subsidiary Guarantor, at the expense of the Obligors and at any time from time to time, upon the written request of the Agent shall promptly and duly execute and deliver such further instruments and documents and take such further actions as the Agent reasonably may request for the purposes of obtaining or preserving the full benefits of this Agreement and of the rights and powers herein granted.

From and after delivery of such joinder, such Person shall be a "Specified Subsidiary Guarantor" for all purposes of this Agreement as if originally party hereto on the date hereof.

At any time after the date hereof, if any Person constituting a Specified Subsidiary Guarantor enters into or incurs any indebtedness under any Additional Indenture, the representative for the holders of the obligations under such Additional Indenture shall, concurrent with the incurrence of indebtedness under such Additional Indenture by any Specified Subsidiary Guarantor, execute and deliver a joinder to this Agreement in substantially the form attached as <u>Exhibit B</u> hereto. From and after delivery of such joinder, such representative shall be a "Trustee" for all purposes of this Agreement as if originally party hereto on the date hereof.
