In calculating Consolidated Interest Expense for purposes of this Consolidated Interest Coverage Ratio:

(a) interest on outstanding Indebtedness determined on a fluctuating basis as of the Transaction Date and which will continue to be so determined thereafter shall be deemed to have accrued at a fixed rate per annum equal to the rate of interest on such Indebtedness in effect on the Transaction Date;

10

(b) if interest on any Indebtedness actually incurred on the Transaction Date may optionally be determined at an interest rate based upon a factor of a prime or similar rate, a eurocurrency interbank offered rate, or other rates, then the interest rate in effect on the Transaction Date will be deemed to have been in effect during the Four-Quarter Period; and

Section 2.12. Defaulted Interest. If the Issuer defaults in a payment of interest on the Notes, it shall pay the defaulted interest in any lawful manner plus, to the extent lawful, interest payable on the defaulted interest, to the Persons who are Holders on a subsequent special record date, which date shall be the earliest practicable date but in all events at least five Business Days prior to the payment date, in each case at the rate provided in the Notes and in Section 4.1. The Issuer shall fix or cause to be fixed each such special record date and payment date and shall promptly thereafter notify the Trustee of any such date. At least 15 days before the special record date, the Issuer (or, at the request of the Issuer, the Trustee, in the name and at the expense of the Issuer) shall mail or cause to be mailed 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 have no duty whatsoever to determine whether any defaulted interest is payable or the amount thereof. Notwithstanding the foregoing, if the Issuer pays the defaulted interest prior to the date that is 30 days after the date of default in payment of interest, no special record date will be set and payment will be made to the Holders as of the original record date.

Section 2.13. Computation of Interest. Interest, if any, on the Notes shall be computed on the basis of a 360-day year comprised of twelve 30-day months.

Section 2.14. CUSIP Number. The Issuer in issuing the Notes may use a “CUSIP” number, and if it does so, the Trustee shall use the CUSIP number in notices of redemption or exchange as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness or accuracy of the CUSIP number printed in the notice or on the Notes and that reliance may be placed only on the other identification numbers printed on the Notes, and any such redemption or exchange shall not be affected by any defect in or omission of such numbers. The Issuer shall promptly notify the Trustee in writing of any change in any CUSIP number.

Section 2.15. Special Transfer Provisions. Each Note issued pursuant to an exemption from registration under the Securities Act (other than in reliance on Regulation S) will constitute a Transfer Restricted Note and be required to bear the Restricted Notes Legend until the date that is six months after the later of the date of original issue and the last date on which the Issuer or any affiliate (within the meaning of Rule 405 under the Securities Act) of the Issuer was the owner of such Notes (or any predecessor thereto), unless and until such Transfer Restricted Note is transferred or exchanged pursuant to an effective registration statement under the Securities Act.

(a) Transfers to QIBs. The following provisions shall apply with respect to the registration of any proposed transfer of a Note issued in reliance on Regulation S to a QIB:

(1) The Registrar shall register the transfer of a Note issued in reliance on Regulation S by a Holder to a QIB if such transfer is being made by a proposed transferor who has provided the Registrar with (a) an appropriately completed certificate of transfer in the form attached to the Note and (b) a certificate substantially in the form set forth in Exhibit C from the proposed transferor; provided that the letter required by this clause (b) shall only be required prior to the expiration of the Restricted Period.

43

(b) Transfers Pursuant to Regulation S. The following provisions shall apply with respect to registration of any proposed transfer of a Transfer Restricted Note pursuant to Regulation S:

(1) The Registrar shall register any proposed transfer of a Transfer Restricted Note by a Holder pursuant to Regulation S upon receipt of (a) an appropriately completed certificate of transfer in the form attached to the Note and (b) a certificate substantially in the form set forth in Exhibit D hereto from the proposed transferor.

(2) If the proposed transferee is a Participant and the Transfer Restricted Note to be transferred consists of an interest in the Rule 144A Global Note or the IAI Global Note upon receipt by the Registrar of (x) the letter, if any, required by paragraph 2.15(b)(1) above and (y) instructions in accordance with the Depositary’s and the Registrar’s procedures therefor, the Registrar shall reflect on its books and records the date and an increase in the principal amount of the Regulation S Global Note in an amount equal to the principal amount of the beneficial interest in the Rule 144A Global Note or the IAI Global Note to be transferred, and the Registrar shall reflect on its books and records the date and a corresponding decrease in the principal amount of the Rule 144A Global Note or the IAI Global Note in an amount equal to the principal amount of the beneficial interest in such Rule 144A Global Note or the IAI Global Note to be transferred.

(c) Transfers to IAIs. The following provisions shall apply with respect to the registration of any proposed transfer of a Note issued in reliance on Rule 144A or Regulation S to an IAI:

(1) The Registrar shall register the transfer of a Note issued in reliance on Rule 144A or Regulation S by a Holder to an IAI if such transfer is being made by a proposed transferor who has provided the Registrar with (a) an appropriately completed certificate of transfer in the form attached to the Note and (b) a certificate substantially in the form set forth in Exhibit E from the proposed transferor.

(2) If the proposed transferee is a Participant and the Note to be transferred consists of an interest in the Rule 144A Global Note or the Regulation S Global Note, upon receipt by the Registrar of (x) the items required by paragraph 2.15(c)(1) above and (y) instructions given in accordance with the Depositary’s and the Registrar’s procedures therefor, the Registrar shall reflect on its books and records the date and an increase in the principal amount of the IAI Global Note in an amount equal to the principal amount of the beneficial interest in the Rule 144A Global Note or the Regulation S Global Note to be so transferred, and the Registrar shall reflect on its books and records the date and a corresponding decrease in the principal amount of such 144A Global Note or the Regulation S Global Note in an amount equal to the principal amount of the beneficial interest in such 144A Global Note or Regulation S Global Note to be so transferred.

(d) In the event that a Global Note is exchanged for Notes in certificated, registered form pursuant to Section 2.6, such Notes may be exchanged only in accordance with such procedures as are substantially consistent with the provisions of clauses (a), (b) and (c) of this Section 2.15 above (including the certification requirements intended to ensure that such transfers comply with Rule 144A, Regulation S or other applicable exemption, as the case may be) and such other procedures as may from time to time be adopted by the Issuer and notified to the Trustee in writing.

44

(e) Restricted Notes Legend. Upon the transfer, exchange or replacement of Notes not bearing the Restricted Notes Legend, the Registrar shall deliver Notes that do not bear the Restricted Notes Legend. Upon the transfer, exchange or replacement of Notes bearing the Restricted Notes Legend, the Registrar shall deliver only Notes that bear the Restricted Notes Legend unless there is delivered to the Registrar an Opinion of Counsel reasonably satisfactory to the Issuer to the effect that neither such legend nor the related restrictions on transfer are required in order to maintain compliance with the provisions of the Securities Act.

(f) Regulation S Legend. Upon the transfer, exchange or replacement of Notes not bearing the Regulation S Legend, the Registrar shall deliver Notes that do not bear the Regulation S Legend.

(g) General. By its acceptance of any Note bearing the Restricted Notes Legend or the Regulation S Legend, as applicable, each Holder of such a Note acknowledges the restrictions on transfer of such Note set forth in this Indenture and in the Restricted Notes Legend or the Regulation S Legend, as applicable, and agrees that it shall transfer such Note only as provided in this Indenture. A transfer of a beneficial interest in a Global Note that does not involve an exchange of such interest for a certificated Note or a beneficial interest in another Global Note shall be subject to compliance with applicable law and the applicable procedures of the Depositary but is not subject to any procedure required by this Indenture.

In connection with any proposed transfer pursuant to Regulation S or pursuant to any other available exemption from the registration requirements of the Securities Act (other than pursuant to Rule 144A), the Issuer may require the delivery of an Opinion of Counsel, other certifications or other information satisfactory to the Issuer.

The Registrar shall retain copies of all letters, notices and other written communications received pursuant to this Section 2.15.

(h) Swiss Transfer Restrictions. The Notes shall not be transferred, publicly offered, sold or advertised, directly or indirectly, in or into Switzerland within the meaning of the Swiss Financial Services Act (the “FinSA”) except to any investor that qualifies as a professional client within the meaning of the FinSA.

Section 2.16. Issuance of Additional Notes. The Issuer shall be entitled to issue Additional Notes in an unlimited aggregate principal amount under this Indenture that shall have identical terms as the Initial Notes, other than with respect to the date of issuance, issue price, first interest payment date applicable thereto, date from which interest will accrue and transfer restrictions; provided that such issuance is not prohibited by the terms of this Indenture, including Section 4.9; provided, further, that if any Additional Notes are not fungible with the Initial Notes for U.S. federal income tax purposes, such Additional Notes shall have a separate CUSIP number from the Initial Notes. The Initial Notes and any Additional Notes shall be treated as a single class for all purposes under this Indenture.

With respect to any Additional Notes, the Issuer shall set forth in an Officers’ Certificate, a copy of which shall be delivered to the Trustee, the following information:

(1) the aggregate principal amount of such Additional Notes to be authenticated and delivered pursuant to this Indenture;

45

(2) the issue price, the issue date, the CUSIP number of such Additional Notes, the first interest payment date and the amount of interest payable on such first interest payment date applicable thereto and the date from which interest shall accrue;

(3) whether such Additional Notes shall be Transfer Restricted Notes; and

(4) that such issuance is not prohibited by this Indenture.

The Trustee shall, upon receipt of the Officers’ Certificate and Opinion of Counsel, authenticate the Additional Notes in accordance with the provisions of Section 2.2 of this Indenture.

Section 2.17. Additional Amounts.

(a) Payments made by or on behalf of the Issuer or any Guarantor, as applicable, on, or in respect of, the Notes or a Guarantee shall be made free and clear of and without withholding or deduction for, or on account of, any present or future income, stamp or other tax, duty, levy, impost, assessment or other similar charges in the nature of a tax, including related penalties and interest (collectively, “Taxes”), unless the Issuer, any Guarantor or the Paying Agent is required to withhold or deduct such amounts by law.

(b) If the Issuer, any Guarantor or the Paying Agent is required to withhold or deduct any amount for or on account of Taxes imposed or levied by or on behalf of the government of the United Kingdom or any other jurisdiction (other than the United States) in which the Issuer or any Guarantor is organized, formed or incorporated or resident for tax purposes or from or through which payments by or on behalf of the Issuer or any Guarantor are made, or any political subdivision or territory thereof (or, in each case, any authority or agency therein or thereof having the power to tax) (each, a “Taxing Jurisdiction”), from any payment made with respect to the Notes or a Guarantee, the Issuer or such Guarantor shall pay such additional amounts (“Additional Amounts”) as may be necessary so that the net amount received by each Holder and beneficial owner (including Additional Amounts) after such withholding or deduction (including any withholding or deduction from such Additional Amounts) shall not be less than the amount the Holder or beneficial owner would have received in respect of such payment on the Notes or the Guarantee if such Taxes had not been withheld or deducted; provided that no Additional Amounts shall be payable with respect to Taxes:

(1) that would not have been imposed or levied but for the existence of any present or former connection (other than the mere acquisition, ownership or holding of, or the receipt of payment or the exercise or enforcement of rights in respect of, the Notes or the Guarantees) between the Holder or beneficial owner of the Notes (or between a fiduciary, settlor, beneficiary, partner, member or shareholder of, or possessor of power over, the relevant Holder or beneficial owner, if such Holder or beneficial owner is an estate, nominee, trust, partnership, limited liability company or corporation) and a Taxing Jurisdiction, including, without limitation, such Holder or beneficial owner being or having been a citizen or resident thereof or treated as a resident thereof or domiciled therein or a national thereof or being or having been present or engaged in trade or business therein or having or having had a permanent establishment therein;

(2) that are estate, inheritance, gift, sales, excise, transfer, personal property, wealth or similar Taxes;

(3) payable other than by deduction or withholding from payments of principal and premium, if any, or interest on the Notes or the Guarantee;

46

(4) that would not have been imposed but for the failure of the applicable recipient of such payment to comply with any reasonable certification, identification, information, documentation or other reporting requirement to the extent: (a) such compliance is required by applicable law or official administrative practice or an applicable treaty as a precondition to exemption from, or reduction in, the rate of deduction or withholding of such Taxes (including, without limitation, a certification that the Holder or beneficial owner is not resident in a Taxing Jurisdiction); and (b) at least 30 days before the first payment date with respect to which such Additional Amounts would otherwise have been payable, the Issuer or Guarantor has notified such recipient in writing that such recipient is required to comply with such requirement;

(5) that would not have been imposed but for the presentation of a Note (where presentation is required) for payment on a date more than 30 days after the date on which such payment became due and payable or the date on which payment thereof was duly provided for, whichever occurred later;

(6) that are imposed or withheld pursuant to Sections 1471 through 1474 of the Code, as of the Issue Date (or any amended or successor version of such sections that is not materially more onerous to comply with), any regulations promulgated thereunder or official interpretations thereof, any similar law, regulation, rule or practice adopted pursuant to or implementing an intergovernmental agreement between a non-U.S. jurisdiction and the United States with respect to the foregoing, or any agreements entered into pursuant to Section 1471(b)(1) of the Code; or

(7) any combination of the foregoing items.

(c) All references in this Indenture or the Notes to the payment of the principal of or premium, if any, or interest on the Notes shall be deemed to include Additional Amounts to the extent that, in that context, Additional Amounts are, were or would be payable in respect thereof. The obligations of the Issuer and any Guarantor to pay Additional Amounts if and when due shall survive the termination of this Indenture and the payment of all other amounts in respect of the Notes and the Guarantees.

(d) The Issuer or Guarantor, as the case may be, shall provide the Trustee with the official acknowledgment of the Taxing Jurisdiction (or, if such acknowledgment is not obtained by the Issuer or Guarantor despite it having used all reasonable efforts to do so, other reasonable documentation) evidencing any payment of any Taxes in respect of which the Issuer or Guarantor has paid any Additional Amounts. Copies of such documentation shall be made available by the Trustee to the Holders or beneficial owners of the Notes or the Paying Agent, as applicable, upon written request therefor.

(e) The Issuer shall pay any stamp, issue, excise, property, registration, court, documentary or other similar taxes and duties (other than, in each case, any such amounts imposed on or measured by net wealth of a holder), including interest, penalties and other liabilities related thereto, imposed by a Taxing Jurisdiction in respect of the creation, issue, delivery, enforcement, registration and offering of the Notes, the initial sale of the Notes by the initial purchasers thereof, or the execution of the Notes, this Indenture or any other related document or instrument, in each case save for any such taxes or duties which arise or are increased as a result of any document being voluntarily registered or voluntarily presented in any court in any jurisdiction by a Holder, beneficial owner or initial purchaser of the Notes (provided that for these purposes any such registration or presentation which, in the reasonable determination of a Holder, beneficial owner or initial purchaser of the Notes (as relevant), is reasonably required to protect its legal or economic interests shall not be regarded as having been voluntarily registered or voluntarily presented), and the Issuer shall indemnify the Holders and beneficial owners of the Notes from and against any such amounts paid by such Holders or beneficial owners.

47

(f) For the avoidance of doubt, the obligations under this Section 2.17 will apply to any successor to the Issuer or any Guarantor.

ARTICLE III

REDEMPTION AND PREPAYMENT

Section 3.1. Notices to Trustee. If the Issuer elects to redeem Notes pursuant to the optional redemption provisions of Section 3.7, it shall furnish to the Trustee, at least two Business Days (or such shorter period as is acceptable to the Trustee) before sending a notice of such redemption, an Officers’ Certificate setting forth the (i) section of this Indenture pursuant to which the redemption shall occur, (ii) redemption date and (iii) principal amount of Notes to be redeemed.

Section 3.2. Selection of Notes to Be Redeemed. In the event that less than all of the Notes are to be redeemed at any time, the Trustee shall, upon the prior written request of the Issuer, select the Notes to be redeemed among the Holders on a pro rata basis (except that any Notes represented by a Global Note will be redeemed by such method the Depositary may require); provided, however, that no Notes of $2,000 in original principal amount or less shall be selected for redemption in part.

On and after the redemption date, unless the Issuer defaults in the payment of the redemption price, interest will cease to accrue on Notes or portions of them called for redemption so long as the Issuer has deposited with the Paying Agent funds in satisfaction of the applicable redemption price pursuant to this Indenture (including accrued and unpaid interest on the Notes to be redeemed). The Trustee shall promptly notify the Issuer in writing of the Notes selected for redemption. The Trustee may select for redemption portions (equal to $1,000 or any integral multiples of $1,000 thereof) of the principal of the Notes that have minimum denominations larger than $2,000.

Section 3.3. Notice of Optional Redemption. The Issuer shall deliver or cause to be delivered in accordance with Section 11.2, a notice of optional redemption to each Holder whose Notes are to be redeemed (with a copy to the Trustee), at least 10 days but not more than 60 days before a redemption date (except that notices may be delivered more than 60 days before a redemption date if the notice is issued in connection with a defeasance or discharge of this Indenture pursuant to Article VIII). Any notice of redemption may, at the Issuer’s discretion, be subject to one or more conditions precedent. If such redemption is subject to satisfaction of one or more conditions precedent, such notice shall describe each such condition, and if applicable, shall state that, in the Issuer’s discretion, the redemption date may be delayed until such time (including more than 60 days after the date the notice of redemption was mailed or delivered, including by electronic transmission) as any or all such conditions are satisfied (or waived by the Issuer in its sole discretion), or that such redemption may not occur and such notice may be rescinded in the event that any or all such conditions are not satisfied (or waived by the Issuer in its sole discretion) by the redemption date, or by the redemption date as so delayed, or that such notice may be rescinded at any time in the Issuer’s discretion if as determined in good faith by the Issuer, any or all of such conditions will not be satisfied. The Issuer shall provide the Trustee with written notice of the satisfaction or waiver of such conditions precedent, the delay of such redemption or the rescission of such notice of redemption in the same manner that the related notice of redemption was given to the Trustee, and the Trustee shall send a copy of such notice to the Trustee to the Holders in the same manner that the related notice of redemption was given to such Holders. In addition, the Issuer may provide in such notice that payment of the redemption price and performance of the Issuer’s obligations with respect to such redemption may be performed by another Person. In no event will the Trustee be responsible for monitoring or charged with knowledge of, the maximum aggregate amount of Notes eligible under this Indenture to be redeemed.

The notice shall identify the Notes to be redeemed (including “CUSIP” numbers and corresponding “ISINs”, if applicable) and shall state:

48

(1) the redemption date;

(2) the redemption price (or the method by which it is to be determined);

(3) if any Note is being redeemed in part, the portion of the principal amount of such Note to be redeemed and that, after the redemption date, upon surrender of such Note, a new Note or Notes in principal amount equal to the unredeemed portion shall be issued upon cancellation of the original Note (or appropriate adjustments to the amount and beneficial interests in a Global Note will be made, as appropriate);

(4) the name and address of the Paying Agent;

(5) that Notes called for redemption must be surrendered to the Paying Agent to collect the redemption price;

(6) that, unless the Issuer defaults in making such redemption payment, interest, if any, on Notes called for redemption ceases to accrue on and after the redemption date;

(7) the paragraph of the Notes and/or Section of this Indenture pursuant to which the Notes called for redemption are being redeemed;

(8) that no representation is made as to the correctness or accuracy of the CUSIP number, if any, listed in such notice or printed on the Notes; and

(9) any conditions precedent to such redemption.

At the Issuer’s written request, the Trustee shall give the notice of redemption in the Issuer’s name and at the Issuer’s expense; provided, however, that the Issuer shall have delivered to the Trustee, at least three Business Days prior to the date of the giving of the notice of redemption (or such shorter period as is acceptable to the Trustee), an Officers’ Certificate requesting that the Trustee give such notice and setting forth the information to be stated in the notice as provided in the preceding paragraph. The notice sent in the manner herein provided shall be deemed to have been duly given whether or not the Holder receives such notice. In any case, failure to give such notice or any defect in the notice to the Holder of any Note shall not affect the validity of the proceeding for the redemption of any other Note.

Section 3.4. Effect of Notice of Redemption. Once notice of redemption is delivered in accordance with Section 3.3, Notes called for redemption become due and payable on the redemption date at the applicable redemption price, subject to satisfaction of any conditions specified in the notice of redemption and as further contemplated by the first paragraph of Section 3.3.

Section 3.5. Deposit of Redemption Price. On or before 11:00 a.m. (New York City time) on the redemption date, the Issuer shall deposit with the Trustee or with the Paying Agent (other than the Issuer or an Affiliate of the Issuer) money sufficient to pay the redemption price on all Notes to be redeemed on that date. The Trustee or the Paying Agent shall promptly return to the Issuer any money deposited with the Trustee or the Paying Agent by the Issuer in excess of the amounts necessary to pay the redemption price of all Notes to be redeemed.

If Notes called for redemption are paid or if the Issuer has deposited with the Trustee or Paying Agent money sufficient to pay the redemption price of, and unpaid and accrued interest, if any, on, all Notes to be redeemed, on and after the redemption date, and interest, if any, shall cease to accrue on the Notes or the portions of Notes called for redemption (regardless of whether certificates for such securities are

49

actually surrendered). If a Note is redeemed on or after an interest record date but on or prior to the related interest payment date, then any accrued and unpaid interest, if any, shall be paid to the Person in whose name such Note was registered at the close of business on such record date. If any Note called for redemption shall not be so paid upon surrender for redemption because of the failure of the Issuer to comply with the preceding paragraph, and interest, if any, shall be paid on the unpaid principal from the redemption date until such principal is paid, and to the extent lawful on any interest, if any, not paid on such unpaid principal, in each case, at the rate provided in the Notes and in Section 4.1.

Section 3.6. Notes Redeemed in Part. Upon surrender and cancellation of a Note that is redeemed in part, the Issuer shall issue and, upon the written request of an Officer of the Issuer, the Trustee shall authenticate for the Holder at the expense of the Issuer a new Note equal in principal amount to the unredeemed portion of the Note surrendered and canceled; provided that each such new Note will be in a principal amount of $2,000 or integral multiples of $1,000 in excess thereof.

Section 3.7. Optional Redemption.

(a) The Notes may be redeemed, in whole or in part, at any time or from time to time prior to April 15, 2026 at the option of the Issuer, upon notice as provided in Section 3.3, at a redemption price equal to 100.0% of the principal amount of the Notes redeemed plus the Applicable Premium, and accrued and unpaid interest thereon, if any, to, but excluding, the redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date that is on or prior to the redemption date). The Issuer will calculate the Treasury Rate and Applicable Premium and, prior to the redemption date, provide an Officers’ Certificate to the Trustee setting forth the Treasury Rate and the Applicable Premium and showing the calculation of each in reasonable detail.

(b) At any time or from time to time on or after April 15, 2026, the Issuer, at its option, may redeem the Notes, in whole or in part, upon notice as provided in Section 3.3, at the redemption prices (expressed as percentages of principal amount of the Notes to be redeemed) set forth below, together with accrued and unpaid interest thereon, if any, to, but excluding, the applicable redemption date (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date that is on or prior to the redemption date), if redeemed during the 12-month period beginning April 15 of the years indicated below:

(c) At any time or from time to time prior to April 15, 2026, the Issuer, at its option, may, on any one or more occasions, redeem up to 40.0% of the principal amount of the outstanding Notes issued under this Indenture, upon notice as provided in Section 3.3, in an amount not greater than the net cash proceeds of one or more Qualified Equity Offerings at a redemption price equal to 108.000% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest, if any, to, but excluding, the date of redemption (subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date); provided that:

(1) at least 60.0% of the aggregate principal amount of Notes originally issued under this Indenture on the Issue Date (excluding Notes held by the Issuer and its Subsidiaries) remains outstanding immediately after giving effect to any such redemption (unless all such Notes are redeemed substantially concurrently); and

50

(2) the redemption occurs not more than 180 days after the date of the closing of any such Qualified Equity Offering.

(d) The Issuer may redeem Notes as provided in Section 4.13(h).

(e) The Issuer may acquire Notes by means other than a redemption, whether pursuant to a tender offer, open market purchase, negotiated transaction or otherwise, in accordance with applicable securities laws.

Section 3.8. Optional Tax Redemption.

(a) The Issuer (or an applicable Successor) may redeem the Notes in whole, but not in part, at its option at any time prior to maturity, upon the giving of not less than 30 nor more than 90 days’ notice of tax redemption to the Holders, at a redemption price equal to the principal amount of the Notes plus accrued and unpaid interest, if any, to, but excluding, the redemption date, if:

(1) as a result of any change in or amendment to the laws, or any regulations, protocols or rulings (including a holding, judgment or order by a governmental agency or court of competent jurisdiction) promulgated thereunder, of a Taxing Jurisdiction or, in the event of the assumption of its obligations under the Notes by a Successor not organized under the laws of a Taxing Jurisdiction pursuant to Section 5.1, the jurisdiction in which such Successor is organized or resident for tax purposes or any political subdivision or territory thereof (or, in each case, any authority or agency therein or thereof having the power to tax), or any change in the application or official interpretation of such laws, regulations, protocols or rulings (including a holding, judgment or order by a governmental agency or court of competent jurisdiction), or (in either case) any change in the application or official interpretation of, or any execution of or amendment to, any treaty or treaties (including protocols) affecting taxation to which any such jurisdiction is a party, which change, execution or amendment is announced and becomes effective on or after (i) the Issue Date or (ii) in the event of the assumption of the Issuer’s obligations under this Indenture and the Notes by a Successor not organized under the laws of a Taxing Jurisdiction pursuant to Section 5.1, with respect to Taxes imposed by the jurisdiction in which such Successor is organized or resident for tax purposes or any political subdivision or territory thereof (or, in each case, any authority or agency therein or thereof having the power to tax), the date of the transaction resulting in such assumption, the Issuer or such Successor, as applicable, would be required to pay Additional Amounts with respect to the Notes on the next succeeding payment date with respect to the Notes, and

(2) the payment of such Additional Amounts cannot be avoided by the use of reasonable measures available to the Issuer or such Successor, as applicable; provided that changing the jurisdiction of the Issuer is not a reasonable measure for purposes of this section.

(b) No notice of any such redemption may be given earlier than 90 days prior to the earliest date on which the Issuer or such Successor, as applicable, would be obligated to pay any Additional Amounts.

(c) The Issuer or such Successor shall also pay to each Holder, or make available for payment to each such Holder, on the redemption date, any Additional Amounts resulting from the payment of such redemption price by it. Prior to the delivery of any notice of redemption, the Issuer or such Successor shall deliver to the Trustee (i) an Officers’ Certificate stating that the requirements referred to in Section 3.8(a) are satisfied, and (ii) an Opinion of Counsel to the effect that the Issuer or such Successor, as applicable, has or will become obliged to pay such Additional Amounts as a result of the change, amendment or execution described above, in each case to be held by the Trustee and made available for viewing at the offices of the Trustee on written request by any Holder. Delivery of any notice of redemption shall be conclusive and binding on the Holders of the Notes being redeemed.

51

(d) Any notice of redemption shall be irrevocable once an Officers’ Certificate has been delivered to the Trustee.

Section 3.9. Certain Tender Offers. If Holders of not less than 90.0% in aggregate principal amount of the outstanding Notes validly tender and do not withdraw such Notes in such tender offer and the Issuer, or any third party approved in writing by the Issuer making such tender offer in lieu of the Issuer, purchases all of the Notes validly tendered and not withdrawn by such Holders, the Issuer or such third party shall have the right upon not less than 10 nor more than 60 days’ prior notice, given not more than 30 days following any such purchase date, to redeem (with respect to the Issuer) or purchase (with respect to a third party) all Notes that remain outstanding following such purchase at a price equal to the price paid to each other Holder in such tender offer plus, to the extent not included in the tender offer payment, accrued and unpaid interest, if any, thereon, to, but excluding, the redemption date or purchase date, subject to the right of Holders of record on the relevant record date to receive interest due on the relevant interest payment date falling on or prior to the redemption date or purchase date.

(b) If the Issuer is not subject to the requirements of Section 13 or 15(d) of the Exchange Act, then the Issuer may satisfy its obligations under this Section 4.3 with respect to the information relating to the Issuer that would be required in Section 4.3(a) by furnishing such financial information relating to any Parent Company; provided that if the financial information so furnished relates to any Parent Company, the same is accompanied by a reasonably detailed description, either on the face of the financial information or in the footnotes thereto and in “Management’s Discussion and Analysis of the Financial Condition and Results of Operations”, of the quantitative differences between the information relating to such Parent Company, on the one hand, and the information relating to the Issuer and the Restricted Subsidiaries on a standalone basis, on the other hand.

(c) If the Issuer has designated any of its Subsidiaries as Unrestricted Subsidiaries, and such Unrestricted Subsidiaries, individually or taken together, would constitute a Significant Subsidiary, then the quarterly and annual financial information required by Section 4.3(a) will include a reasonably detailed presentation, either on the face of the financial statements or in the footnotes thereto, and in Management’s Discussion and Analysis of Financial Condition and Results of Operations, of the financial condition and results of operations of the Issuer and its Restricted Subsidiaries excluding the Unrestricted Subsidiaries.

(1) not later than 15 Business Days after filing or furnishing a copy of each, use its commercially reasonable efforts, consistent with its judgment as to what is prudent at the time, to participate in quarterly conference calls after the delivery of the reports referred to in Section 4.3(a)(1) with the SEC or the Trustee, hold a conference call to discuss the results of operations for the relevant reporting period (the Issuer may satisfy the requirements of this clause (d)(1) by holding the required conference call within the time period required by this clause (d)(1) as part of any earnings call of the Issuer or any Parent Company); and

53

(2) issue a press release or otherwise publicly announce no fewer than two Business Days prior to the date of any conference call required to be held in accordance with this paragraph, announcing the time and date of such conference call and either including all information necessary to access the call or directing Holders, prospective investors, broker-dealers and securities analysts to contact the appropriate person at the Issuer to contact the appropriate person at the Issuer to obtain such information.

(f) Any and all Defaults arising from a failure to furnish in a timely manner any information or notice required by this covenant shall be deemed cured (and the Issuer shall be deemed to be in compliance with this Section 4.3) upon furnishing such information or notice as contemplated by this Section 4.3 (but without regard to the date on which such information or notice is so furnished).

(g) For so long as any Notes remain outstanding, the Issuer shall furnish to the Holders and to securities analysts and prospective investors, upon their request, the information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act.

(h) Delivery of such reports, information and documents to the Trustee is for informational purposes only, and the Trustee’s receipt thereof shall not constitute actual or constructive knowledge or notice of any information contained therein or determinable from information contained therein, including the Issuer’s, any Guarantor’s or any other person’s compliance with any of the covenants in this Indenture or the Notes (as to which the Trustee is entitled to rely exclusively on Officers’ Certificates). The Trustee will not be obligated to monitor or confirm, on a continuing basis or otherwise, the Issuer’s, any Guarantor’s or any other person’s compliance with any of the covenants described herein or to determine whether such reports, information or documents have been posted on any website or other online data system or filed with the SEC through EDGAR (or other applicable system), to examine such reports, information, documents to ensure compliance with the provisions of this Indenture, to ascertain the correctness or otherwise of the information or the statements contained therein, or to participate in any conference calls.

Section 4.4. Compliance Certificate. The Issuer shall deliver to the Trustee, within 90 days after the end of each fiscal year beginning with the fiscal year ending December 31, 2023, an Officers’ Certificate stating that a review of the activities of the Issuer and its Subsidiaries during the preceding fiscal year has been made under the supervision of the signing Officers with a view to determining whether each has kept, observed, performed and fulfilled its obligations under this Indenture, and further stating, as to each such Officer signing such certificate, that, to his or her knowledge, each entity has kept, observed, performed and fulfilled each and every covenant contained in this Indenture and is not in default in the performance or observance of any of the terms, provisions and conditions of this Indenture (or, if a Default or Event of Default shall have occurred, describing all such Defaults or Events of Default of which he or she may have knowledge and what action the Issuer is taking or proposes to take with respect thereto) and that, to his or her knowledge, no event has occurred and remains in existence by reason of which payments on account of the principal of, premium, if any, or interest, if any, on the Notes is prohibited or if such event has occurred, a description of the event and what action the Issuer is taking or proposes to take with respect thereto.

54

The Issuer shall, so long as any of the Notes are outstanding, deliver to the Trustee, within 30 days after upon any Officer becomes aware of any Default or Event of Default, an Officers’ Certificate specifying such Default or Event of Default and what action the Issuer is taking or proposes to take with respect thereto.

Section 4.5. Taxes. The Issuer shall pay, and shall cause each of its Subsidiaries to pay, prior to delinquency all material taxes, assessments and governmental levies, except such as are contested in good faith and by appropriate proceedings and with respect to which appropriate reserves have been taken in accordance with GAAP or where the failure to effect such payment is not adverse in any material respect to the Holders of the Notes.

Section 4.6. Stay, Extension and Usury Laws. The Issuer and each of the Guarantors covenants (to the extent that it may lawfully do so) that it shall not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay, extension or usury law wherever enacted, now or at any time hereafter in force, that may affect the covenants or the performance of this Indenture, and the Issuer and each of the Guarantors (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it shall not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee, but shall suffer and permit the execution of every such power as though no such law has been enacted.

Section 4.7. Limitation on Restricted Payments.

(a) The Issuer shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, make any Restricted Payment if at the time of such Restricted Payment:

(1) a Payment Default or Event of Default shall have occurred and be continuing or shall occur as a consequence thereof;

(2) the Issuer is not able to incur at least $1.00 of additional Indebtedness pursuant to the Coverage Ratio Exception; and

(3) the amount of such Restricted Payment, when added to the aggregate amount of all other Restricted Payments made after the Issue Date (other than Restricted Payments made pursuant to Sections 4.7(b)(2) through (10), Section 4.7(b)(11)(A) and Section 4.7(b)(12); provided that Restricted Payments made after the Issue Date pursuant to Section 4.7(b)(11)(B) shall not cause the amount calculated pursuant to Section 4.7(a)(3)(A) to be less than zero for any fiscal period), exceeds the sum (the “Restricted Payments Builder Basket”) of (without duplication):

(A) 50.0% of Consolidated Net Income of the Issuer and the Restricted Subsidiaries for the period (taken as one accounting period) commencing on April 1, 2023 to and including the last day of the fiscal quarter ended immediately prior to the date of such calculation for which consolidated financial statements are available (or, if such Consolidated Net Income shall be a deficit, minus 100.0% of such deficit), plus

(B) 100.0% of (i) the aggregate net cash proceeds, or the Fair Market Value of any assets or Equity Interests of any Person engaged in a Permitted Business, in each case received by the Issuer or its Restricted Subsidiaries on or after the Issue Date as a contribution to the Issuer’s common equity capital or from the issue or sale of Qualified Equity Interests of the Issuer or from the issue or sale of convertible or exchangeable Disqualified Equity Interests of the Issuer or convertible or exchangeable debt securities of the Issuer that have been converted into or exchanged for such Qualified Equity Interests (other than Equity Interests or debt securities issued or sold to a Subsidiary of the Issuer or net cash proceeds received by the Issuer from Qualified Equity Offerings to the extent applied to redeem the Notes in accordance with the provisions set forth under Section 3.7(c)), and (ii) the aggregate net cash proceeds, if any, received by the Issuer or any of its Restricted Subsidiaries upon any conversion or exchange described in clause (i) above, plus

(D) upon a Redesignation of an Unrestricted Subsidiary as a Restricted Subsidiary, an amount (to the extent not included in the computation of Consolidated Net Income) equal to the lesser of (i) the Fair Market Value of the Issuer’s proportionate interest in such Subsidiary immediately following such Redesignation, and (ii) the aggregate amount of the Issuer’s Investments in such Subsidiary to the extent such Investments reduced the Restricted Payments Builder Basket and were not previously repaid or otherwise reduced.

(4) the purchase, repurchase, redemption, defeasance or other acquisition or retirement for value of Subordinated Indebtedness of the Issuer or any Restricted Subsidiary (A) at a purchase price not greater than 101.0% of the principal amount of such Subordinated Indebtedness in the event of a Change of Control in accordance with provisions similar to Section 4.13 or (B) at a purchase price not greater than 100.0% of the principal amount thereof in accordance with provisions similar to Section 4.10; provided that, prior to or simultaneously with such purchase, repurchase, redemption, defeasance or other acquisition or retirement, the Issuer has made the Change of Control Offer or Net Proceeds Offer, as applicable, as provided in such covenant with respect to the Notes and has completed the repurchase or redemption of all Notes validly tendered for payment in connection with such Change of Control Offer or Net Proceeds Offer;

(5) so long as no Payment Default or Event of Default has occurred and is continuing or would result therefrom, redemptions, repurchases or other acquisitions or retirements for value by the Issuer of, or distributions to any Parent Company to permit such Parent Company to redeem, repurchase, or otherwise acquire or retire for value, Equity Interests of the Issuer or any Parent Company held by officers, directors or employees or former officers, directors or employees (or their transferees, estates or beneficiaries under their estates), either (x) upon any such individual’s death, disability, retirement, severance or termination of employment or service or (y) pursuant to

56

any equity subscription agreement, stock option agreement, stockholders’ agreement or similar agreement; provided, in any case, that the aggregate cash consideration paid for all such redemptions, repurchases or other acquisitions or retirements shall not exceed (A) $20.0 million during any calendar year (with unused amounts in any calendar year being carried forward to succeeding calendar years) plus (B) the amount of any net cash proceeds received by or contributed to the Issuer or any Parent Company (to the extent received by or contributed to the Issuer or any Restricted Subsidiary) from the issuance and sale after the Issue Date of Qualified Equity Interests to its officers, directors or employees that have not been applied to the payment of Restricted Payments pursuant to this clause (5), plus (C) the net cash proceeds of any “key-man” life insurance policies that have not been applied to the payment of Restricted Payments pursuant to this clause (5);

(7) so long as no Payment Default or Event of Default has occurred and is continuing or would result therefrom, dividends or distributions on Disqualified Equity Interests of the Issuer or any Restricted Subsidiary or on any Preferred Stock of any Restricted Subsidiary, in each case issued in compliance with Section 4.9 to the extent such dividends or distributions are included in the definition of Consolidated Interest Expense;

(8) the payment of cash in lieu of fractional Equity Interests of the Issuer;

(9) payments or distributions to dissenting stockholders pursuant to applicable law in connection with a merger, consolidation or transfer of assets that complies with Section 5.1;

(10) cash distributions by the Issuer to the holders of Equity Interests of the Issuer in accordance with a distribution reinvestment plan or dividend reinvestment plan to the extent such payments are applied to the purchase of Equity Interests directly from the Issuer;

(12) Permitted Payments to Parent.

provided that no issuance and sale of Qualified Equity Interests used to make a payment pursuant to clauses (2) or (5)(B) above shall increase the Restricted Payments Builder Basket to the extent of such payment.

For purposes of determining compliance with this Section 4.7, in the event that any Restricted Payment or Investment (or a portion thereof) meets the criteria of more than one of the categories of Restricted Payments described in Section 4.7(a) or Sections 4.7(b)(1) through (12) and/or one or more of

57

the clauses contained in the definition of “Permitted Investments,” the Issuer will, in its sole discretion, be entitled to divide or classify (or later divide, classify or reclassify), in whole or in part, such Restricted Payment or Investment (or any portion thereof) among Section 4.7(a) and/or such Sections 4.7(b)(1) through (12) and/or one or more clauses contained in the definition of “Permitted Investments” in a manner that otherwise complies with this covenant.

If any Person in which an Investment is made, which Investment constitutes a Restricted Payment when made, thereafter becomes a Restricted Subsidiary in accordance with this Indenture, all such Investments previously made in such Person shall be Permitted Investments under clause (1)(b) of the definition thereof, and for the avoidance of doubt, all such Investments shall no longer be counted as Restricted Payments for purposes of calculating the aggregate amount of Restricted Payments pursuant to clause (3) of the definition of “Restricted Payments”, in each case, to the extent such Investments would otherwise be so counted.

For the purposes of determining compliance with any U.S. dollar-denominated restriction on Restricted Payments denominated in a foreign currency, the U.S. dollar-equivalent amount of such Restricted Payment shall be calculated based on the relevant currency exchange rate in effect on the date that such Restricted Payment was made. The amount of any Restricted Payment (other than cash) will be the Fair Market Value on the date of the Restricted Payment (or, in the case of a dividend, on the date of declaration) of the assets or securities proposed to be transferred or issued by the Issuer or such Restricted Subsidiary, as the case may be, pursuant to the Restricted Payment.

Section 4.8. Limitation on Dividend and Other Restrictions Affecting Restricted Subsidiaries. (a) The Issuer shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, create or otherwise cause or permit to exist or become effective any consensual encumbrance or consensual restriction on the ability of any Restricted Subsidiary to:

(1) pay dividends or make any other distributions on or in respect of its Equity Interests to the Issuer or any of its Restricted Subsidiaries, or with respect to any other interest or participation in, or measured by, its profits (it being understood that the priority of any Preferred Stock in receiving dividends or liquidating distributions prior to dividends or liquidating distributions being paid on Common Stock shall not be deemed a restriction on the ability to make distributions on Equity Interests);

(2) make loans or advances, or pay any Indebtedness or other obligation owed, to the Issuer or any other Restricted Subsidiary (it being understood that the subordination of loans or advances made to the Issuer or any Restricted Subsidiary to other Indebtedness or obligations incurred by the Issuer or any Restricted Subsidiary shall not be deemed a restriction on the ability to make loans or advances); or

(3) transfer any of its property or assets to the Issuer or any other Restricted Subsidiary (it being understood that such transfers shall not include any type of transfer described in clause (1) or (2) above);

(b) Notwithstanding the foregoing, Section 4.8(a) shall not prohibit, encumbrances or restrictions:

(1) existing under the RCF Credit Agreement existing on the Issue Date or any other agreements existing on the Issue Date;

(2) existing under this Indenture, the Notes and the Guarantees;

58

(3) existing under any instrument governing Acquired Indebtedness or Equity Interests of a Person acquired by the Issuer or any of its Restricted Subsidiaries, which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person or the properties or assets of the Person so acquired;

(4) existing under any agreement or other instrument of a Person acquired by the Issuer or any of its Restricted Subsidiaries in existence at the time of such acquisition (but not created in contemplation thereof), which encumbrance or restriction is not applicable to any Person, or the properties or assets of any Person, other than the Person and its Subsidiaries, or the property or assets of the Person and its Subsidiaries, so acquired (including after acquired property);

(5) existing under any amendment, restatement, modification, renewal, increases, supplement, refunding, replacement or refinancing of an agreement referred to in clauses (1), (2), (3), (4) or (10) of this Section 4.8(b) or this clause (5); provided, however, that such encumbrances and restrictions contained in such amendments, restatements, modifications, renewals, increases, supplements, refunding, replacements or refinancing are, in the good faith judgment of the Issuer, not materially more restrictive, taken as a whole, than such encumbrances and restrictions contained in the agreements referred to in such clauses on the Issue Date or the date such Restricted Subsidiary became a Restricted Subsidiary or was merged into a Restricted Subsidiary, whichever is applicable;

(6) existing under or by reason of applicable law, regulation or order;

(7) resulting from non-assignment provisions of any contract, including any charter party agreement, drilling contract or any demise, bareboat, time voyage, other charter or any lease, entered into in the ordinary course of business;

(8) in the case of Section 4.8(a)(3) above, encumbrances or restrictions permitted to be incurred under the provisions of Section 4.12 that limit the right of the debtor to dispose of the assets securing such Indebtedness;

(9) imposed under any agreement to sell Equity Interests or assets, as permitted under this Indenture, to any Person pending the closing of such sale;

(10) (A) resulting from any other agreement governing Indebtedness or other obligations entered into after the Issue Date that contains encumbrances and restrictions that in the good faith judgment of the Issuer are not materially more restrictive, taken as a whole, with respect to any Restricted Subsidiary than those in effect on the Issue Date pursuant to agreements in effect on the Issue Date or those contained in this Indenture, the Notes and the Guarantees or (B) contained in agreements or instruments governing such Indebtedness that is customary and does not prohibit (except upon a default or an event of default thereunder) the payment of dividends in an amount sufficient, as determined by the Issuer in good faith, to make scheduled payments of cash interest and principal on the Notes when due;

(11) as a result of customary provisions in partnership agreements, limited liability company organizational governance documents, joint venture agreements, shareholder agreements and other similar agreements entered into in the ordinary course of business that restrict the disposition or distribution of ownership interests in or assets of such partnership, limited liability company, joint venture, corporation or similar Person;

59

(12) resulting from any agreement governing Purchase Money Indebtedness and any Refinancing Indebtedness in respect thereof incurred in compliance with Section 4.9 that imposes restrictions of the nature described in Section 4.8(a)(3) on the assets acquired;

(13) on cash or other deposits or net worth imposed by customers, suppliers or landlords under contracts entered into in the ordinary course of business;

(14) with respect to an Unrestricted Subsidiary or Equity Interests thereof pursuant to or by reason of an agreement that the Unrestricted Subsidiary is a party to entered into before the date on which such Unrestricted Subsidiary became a Restricted Subsidiary; provided that such agreement was not entered into in anticipation of the Unrestricted Subsidiary becoming a Restricted Subsidiary and any such encumbrance or restriction shall not extend to any assets or property of the Issuer or any other Restricted Subsidiary other than the assets and property so acquired; and

(15) resulting from supermajority voting requirements existing under corporate charters, by-laws, stockholders agreements and similar documents and agreements.

In each case set forth above, notwithstanding any stated limitation on the assets or property that may be subject to such encumbrance or restriction, an encumbrance or restriction on a specified asset or property or group or type of assets or property may also apply to all improvements, additions, repairs, attachments or accessions thereto, assets and property affixed or appurtenant thereto, parts, replacements and substitutions therefor, and all products and proceeds thereof, including dividends, distributions, interest and increases in respect thereof.

Section 4.9. Limitation on Additional Indebtedness.

(a) The Issuer shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, incur any Indebtedness (including Acquired Indebtedness); provided that the Issuer and any of its Restricted Subsidiaries may incur additional Indebtedness (including Acquired Indebtedness), in each case, if, after giving effect thereto on a pro forma basis (including giving pro forma effect to the application of the proceeds thereof), the Issuer’s Consolidated Interest Coverage Ratio would be at least 2.00 to 1.00; provided, further, that Restricted Subsidiaries that are not Guarantors may not incur any Indebtedness pursuant to this Section 4.9(a) if the aggregate principal amount of all then outstanding Indebtedness incurred by Restricted Subsidiaries that are not Guarantors pursuant to this Section 4.9(a) exceeds the greater of (i) $50.0 million and (ii) 1.0% of the Issuer’s Consolidated Total Assets determined at the time of incurrence (the “Coverage Ratio Exception”).

(b) Notwithstanding the above, each of the following incurrences of Indebtedness shall be permitted (the “Permitted Indebtedness”):

(1) Indebtedness of the Issuer or any Restricted Subsidiary under one or more Debt Facilities in an aggregate principal amount at any time outstanding, including the issuance and creation of letters of credit and bankers’ acceptances thereunder (with letters of credit and bankers’ acceptances being deemed to have a principal amount equal to the face amount thereof) not to exceed the greater of (A) $750.0 million and (B) 15.0% of the Issuer’s Consolidated Total Assets determined at the time of incurrence;

(2) Indebtedness represented by (A) the Notes issued on the Issue Date (excluding any Additional Notes) and (B) the Guarantees of the Notes issued on the Issue Date (excluding any Additional Notes);

(4) guarantees by the Issuer or any Restricted Subsidiary of Indebtedness permitted to be incurred in accordance with the provisions of this Indenture; provided that in the event such Indebtedness that is being guaranteed is Subordinated Indebtedness, then the related guarantee shall be subordinated in right of payment to the Notes;

(5) Indebtedness under Hedging Obligations entered into for bona fide hedging purposes of the Issuer or any Restricted Subsidiary in the ordinary course of business and not for the purpose of speculation; provided that in the case of Hedging Obligations relating to interest rates, (A) such Hedging Obligations relate to payment obligations on Indebtedness otherwise permitted to be incurred by this Section 4.9, and (B) the notional principal amount of such Hedging Obligations at the time incurred does not exceed the principal amount of the Indebtedness to which such Hedging Obligations relate;

(6) Indebtedness of the Issuer owed to and held by a Restricted Subsidiary and Indebtedness of any Restricted Subsidiary owed to and held by the Issuer or any other Restricted Subsidiary; provided, however, that

(B) if a Guarantor is the obligor on such Indebtedness and a Restricted Subsidiary that is not a Guarantor is the obligee, such Indebtedness is subordinated in right of payment to the Guarantee of such Guarantor; and

(C) (i) any subsequent issuance or transfer of Equity Interests or any other event which results in any such Indebtedness being held by a Person other than the Issuer or any other Restricted Subsidiary; and

(ii) any sale or other transfer of any such Indebtedness to a Person other than the Issuer or any other Restricted Subsidiary shall be deemed, in each case of this subclause (C), to constitute an incurrence of such Indebtedness not permitted by this clause (6);

(15) Indebtedness of Persons incurred and outstanding on the date on which such Person was acquired by the Issuer or any Restricted Subsidiary, or merged or consolidated with or into the Issuer or any Restricted Subsidiary or incurred by the Issuer or any Restricted Subsidiary to finance any such acquisition or merger; provided, however, that at the time such Person or assets is/are acquired by the Issuer or a Restricted Subsidiary, or merged or consolidated with the Issuer or any Restricted Subsidiary and after giving pro forma effect to the incurrence of such Indebtedness pursuant to this clause (15) and any other related Indebtedness and the application of proceeds therefrom, either (A) the Issuer would have been able to incur $1.00 of additional Indebtedness pursuant to the Coverage Ratio Exception; or (B) the Consolidated Interest Coverage Ratio of the Issuer and its Restricted Subsidiaries would be greater than or equal to such Consolidated Interest Coverage Ratio immediately prior to such acquisition, merger or consolidation;

(16) Indebtedness in respect of letters of credit, bankers’ acceptances, letters of guaranty and similar credit transactions (or reimbursement agreements in respect thereof and with each such instrument being deemed to have a principal amount equal to the face amount thereof) at any one time outstanding not to exceed the greater of (x) $50.0 million and (y) 1.0% of the Issuer’s Consolidated Total Assets determined at the time of incurrence;

62

(17) Indebtedness consisting of the financing of insurance premiums; and

(18) to the extent constituting Indebtedness, prepayments for property or services under any drilling contract, pool agreement or charter party agreement in the ordinary course of business.

(c) For purposes of determining compliance with this Section 4.9, in the event that an item of Indebtedness meets the criteria of more than one of the categories of Permitted Indebtedness described in clauses (1) through (18) above, or is entitled to be incurred pursuant to the Coverage Ratio Exception, the Issuer will be permitted, in its sole discretion, to divide and classify such item of Indebtedness, or later reclassify all or a portion of such item of Indebtedness (provided that at the time of reclassification it meets the criteria in such category or categories), in any manner that complies with this Section 4.9; provided, that Indebtedness incurred under the RCF Credit Agreement on the Issue Date shall be deemed to have been incurred under clause (1) above and may not be reclassified. In addition, for purposes of determining any particular amount of Indebtedness under this covenant, the amount of Indebtedness issued at a price that is less than the principal amount thereof will be equal to the amount of the liability in respect thereof determined in accordance with GAAP.

(d) The accrual of interest, the accretion or amortization of original issue discount and the payment of interest on any Indebtedness in the form of additional Indebtedness with the same terms will not be deemed to be an incurrence of Indebtedness under this Section 4.9; provided, in each such case, that the amount thereof is included in Consolidated Interest Expense of the Issuer as accrued.

(e) For the purposes of determining compliance with any U.S. dollar-denominated restriction on the incurrence of Indebtedness denominated in a foreign currency, the U.S. dollar-equivalent principal amount of such Indebtedness incurred pursuant thereto shall be calculated based on the relevant currency exchange rate in effect on the earlier of the date that such Indebtedness was incurred, in the case of term Indebtedness, or first committed, in the case of revolving credit Indebtedness; provided that if such Indebtedness is incurred to refinance other Indebtedness denominated in a foreign currency, and such refinancing would cause the applicable U.S. dollar-denominated restriction to be exceeded if calculated at the relevant currency exchange rate in effect on the date of such refinancing, such U.S. dollar-denominated restriction shall be deemed not to have been exceeded so long as the principal amount of such Refinancing Indebtedness does not exceed the principal amount of such Indebtedness being refinanced. The principal amount of any Indebtedness incurred to refinance other Indebtedness, if incurred in a different currency from the Indebtedness being refinanced, shall be calculated based on the currency exchange rate applicable to the currencies in which such Refinancing Indebtedness is denominated that is in effect on the date of such refinancing.

(f) If at any time an Unrestricted Subsidiary becomes a Restricted Subsidiary, any Indebtedness of such Subsidiary shall be deemed to be incurred by a Restricted Subsidiary as of such date (and, if such Indebtedness is not permitted to be incurred as of such date under this Section 4.9, the Issuer shall be in Default of this Section 4.9).

(g) Notwithstanding anything to the contrary in this Section 4.9, in the event an item of Indebtedness (or any portion thereof) is incurred or issued, any Lien is incurred or other transaction is undertaken in reliance on any ratio based exceptions, thresholds and baskets, such ratio(s) shall be calculated with respect to such incurrence, issuance or other transaction without giving effect to amounts being utilized under any other exceptions, thresholds or baskets (other than ratio based baskets) on the same date. Each item of Indebtedness that is incurred or issued, each Lien incurred and each other transaction undertaken shall be deemed to have been incurred, issued or taken first, to the extent available, pursuant to the relevant ratio based test.

63

(h) If any Indebtedness is incurred in reliance on a basket measured by reference to the Consolidated Total Debt Ratio or a percentage of Consolidated Total Assets, and any refinancing thereof would cause the Consolidated Total Debt Ratio or the percentage of Consolidated Total Assets to be exceeded if calculated based on the Consolidated Total Debt Ratio or Consolidated Total Assets, as applicable, on the date of such refinancing, such Consolidated Total Debt Ratio or percentage of Consolidated Total Assets, as applicable, will not be deemed to be exceeded to the extent the principal amount of such newly incurred Indebtedness does not exceed the sum of (i) the principal amount of such Indebtedness being refinanced, extended, replaced, refunded, renewed or defeased, plus (ii) any accrued and unpaid interest on the Indebtedness (or any accrued and unpaid dividends on the Preferred Stock and any accrued and unpaid dividends on the Disqualified Equity Interests, as applicable) being so refinanced, extended, replaced, refunded, renewed or defeased, plus (iii) the amount of any tender premium or penalty or premium required to be paid under the terms of the instrument or documents governing such refinanced Indebtedness and any defeasance costs and any fees and expenses (including original issue discount, upfront fees or similar fees) incurred in connection with the issuance of such new Indebtedness or the extension, replacement, refunding, refinancing, renewal or defeasance of such refinanced Indebtedness.

Section 4.10. Limitation on Asset Sales.

(a) The Issuer shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, consummate any Asset Sale unless:

(1) the Issuer or such Restricted Subsidiary, as the case may be, receives consideration (including by way of relief from, or by any Person assuming responsibility for any liability, contingent or otherwise, in connection with the Asset Sale) at least equal to the Fair Market Value (such Fair Market Value to be determined on the date of contractually agreeing to such Asset Sale) of the Equity Interests or assets subject to such Asset Sale; and

(2) except in the case of an Asset Swap, at least 75.0% of the total consideration from such Asset Sale and all other Asset Sales on a cumulative basis since the Issue Date received by the Issuer or a Restricted Subsidiary, as the case may be, is in the form of cash or Cash Equivalents.

For purposes of clause (a)(2) above and for no other purpose, the following shall be deemed to be cash:

(A) the amount (without duplication) of any liabilities (as shown on the Issuer’s or such Restricted Subsidiary’s most recent balance sheet or in the notes thereto or, if incurred or accrued subsequent to the date of such balance sheet, such liabilities that would have been reflected on the Issuer’s or a Restricted Subsidiary’s consolidated balance sheet or in the notes thereto if such incurrence or accrual had taken place on or prior to the date of such balance sheet, as determined in good faith by the Issuer) (other than Subordinated Indebtedness or intercompany Indebtedness) of the Issuer or such Restricted Subsidiary that are cancelled, terminated or expressly assumed by the transferee of any such assets pursuant to a written agreement that releases the Issuer or such Restricted Subsidiary from further liability therefor or indemnifies the Issuer or such Restricted Subsidiary against further liability;

(B) the amount of any securities, notes or other obligations received from such transferee that are within 180 days after such Asset Sale converted by the Issuer or such Restricted Subsidiary into cash (to the extent of the cash actually so received);

(C) any assets or Equity Interests of the kind referred to in Section 4.10(b)(2);

64

(D) accounts receivable of a business retained by the Issuer or any Restricted Subsidiary, as the case may be, following the sale of such business; provided that such accounts receivable (i) are not past due more than 60 days and (ii) do not have a payment date greater than 90 days from the date of the invoices creating such accounts receivable; and

(E) any Designated Non-cash Consideration received by the Issuer or such Restricted Subsidiary in such Asset Sale having an aggregate Fair Market Value, taken together with all other Designated Non-cash Consideration received pursuant to this clause (E), not to exceed an amount equal to 5.0% of the Issuer’s Consolidated Total Assets (determined at the time of receipt of such Designated Non-cash Consideration), with the Fair Market Value of each item of Designated Non-cash Consideration being measured at the time received and without giving effect to subsequent changes in value.

In the case of any Asset Sale pursuant to a condemnation, seizure, appropriation or similar taking, including by deed in lieu of condemnation, or any actual or constructive total loss or an agreed or compromised total loss, such Asset Sale shall not be required to satisfy the requirements of clauses (1) and (2) of this Section 4.10(a).

(b) If the Issuer or any Restricted Subsidiary engages in an Asset Sale, the Issuer or such Restricted Subsidiary may, no later than 365 days following the receipt of any Net Available Proceeds therefrom, apply all or any of the Net Available Proceeds therefrom to:

(1) repay, repurchase, redeem, defease or otherwise retire any Indebtedness of the Issuer or a Restricted Subsidiary (other than any Subordinated Indebtedness of the Issuer or a Guarantor, and other than Indebtedness owed to the Issuer or an Affiliate of the Issuer); or

(2) (A) to make any capital expenditure not prohibited under this Indenture, (B) acquire Qualified Equity Interests held by a Person other than the Issuer or any of its Restricted Subsidiaries in a Person that is a Restricted Subsidiary or in a Person engaged in a Permitted Business that shall become a Restricted Subsidiary immediately upon the consummation of such acquisition or (C) a combination of (A) and (B); provided that the requirements of this clause (b)(2) shall be deemed to be satisfied with respect to any Asset Sale if the Issuer or any Restricted Subsidiary enters into an agreement committing to make the acquisition, investment or expenditure referred to above within 365 days after the receipt of such Net Available Proceeds with the good faith expectation that such Net Available Proceeds will be applied to satisfy such commitment in accordance with such agreement within 180 days after such 365-day period, and if such Net Available Proceeds are not so applied within such 180-day period, then such Net Available Proceeds shall constitute Excess Proceeds (as defined below).

The amount of Net Available Proceeds not applied or invested as provided in clauses (1) or (2) of this Section 4.10(b) shall constitute “Excess Proceeds.”

(c) On the 366th day after an Asset Sale (or, at the Issuer’s option, an earlier date), if the aggregate amount of Excess Proceeds equals or exceeds $75.0 million, the Issuer shall be required to make an offer, with a copy to the Trustee, to purchase or redeem (a “Net Proceeds Offer”) from all Holders and, to the extent required by the terms of other Pari Passu Indebtedness of the Issuer, to all holders of other Pari Passu Indebtedness outstanding with similar provisions requiring the Issuer to make an offer to purchase or redeem such Pari Passu Indebtedness with the proceeds from any Asset Sale to purchase or redeem the maximum principal amount of Notes and any such Pari Passu Indebtedness to which the Net Proceeds Offer applies that may be purchased or redeemed out of the Excess Proceeds, at an offer price in cash in an amount equal to 100.0% of the principal amount of Notes and Pari Passu Indebtedness plus accrued and unpaid interest thereon, if any, to the date of purchase, in accordance with the procedures set forth in this Indenture or the agreements governing the Pari Passu Indebtedness, as applicable, in each case in minimum denominations of $2,000 or integral multiples of $1,000 in excess thereof.

65

Notwithstanding any other provisions of this covenant, (i) to the extent that any of or all the Net Available Proceeds of any Asset Sales is prohibited or delayed by applicable law, the portion of such Net Available Proceeds so affected will not be required to be applied in compliance with this Section 4.10, and such amounts may be retained by the Issuer or Subsidiary, as applicable, so long, but only so long, as the applicable law will not permit repatriation to the United States or the United Kingdom (the Issuer hereby agreeing to use reasonable efforts (as determined in the Issuer’s good faith judgment) to, or otherwise cause the applicable Subsidiary to, promptly take all actions reasonably required by the applicable law to permit such repatriation), and once such repatriation of any of such affected Net Available Proceeds is permitted under the applicable law, such repatriation will be promptly effected and such repatriated Net Available Proceeds will be promptly (and in any event not later than five Business Days after such repatriation could be made) applied (net of additional taxes payable or reserved against as a result thereof) (whether or not repatriation actually occurs) in compliance with this Section 4.10 and (ii) to the extent that the Issuer has determined in good faith that repatriation of any of or all the Net Available Proceeds of any such prohibited or delayed Asset Sale would have a material adverse tax cost consequence with respect to such Net Available Proceeds (which for the avoidance of doubt, may include, but is not limited to, any prepayment whereby doing so the Issuer, any Restricted Subsidiary or any of their respective Affiliates and/or equity partners would incur a tax liability, including as a result of a dividend or a deemed dividend, or a withholding tax), the Net Available Proceeds so affected may be retained by the applicable Subsidiary. The non-application of any prepayment amounts as a consequence of the foregoing provisions will not, for the avoidance of doubt, constitute a Default or an Event of Default. The Trustee shall be entitled to conclusively rely on an Officer’s Certificate from the Issuer to the effect that applicable law will not permit repatriation of such amounts to the United States.

To the extent that the sum of the aggregate principal amount of Notes and Pari Passu Indebtedness so validly tendered pursuant to a Net Proceeds Offer is less than the Excess Proceeds, the Issuer may use any remaining Excess Proceeds, or a portion thereof, for any purposes not otherwise prohibited by the provisions of this Indenture. If the aggregate principal amount of Notes and Pari Passu Indebtedness so validly tendered pursuant to a Net Proceeds Offer exceeds the amount of Excess Proceeds, the Issuer shall select the Notes and Pari Passu Indebtedness to be purchased on a pro rata basis on the basis of the aggregate outstanding principal amount of Notes and Pari Passu Indebtedness. Upon completion of such Net Proceeds Offer in accordance with the foregoing provisions, the amount of Excess Proceeds with respect to which such Net Proceeds Offer was made shall be deemed to be zero.

(d) The Net Proceeds Offer will remain open for a period of 20 Business Days following its commencement, except to the extent that a longer period is required by applicable law (the “Net Proceeds Offer Period”). No later than five Business Days after the termination of the Net Proceeds Offer Period (the “Net Proceeds Purchase Date”), the Issuer will purchase the principal amount of Notes and Pari Passu Indebtedness required to be purchased pursuant to this Section 4.10 (the “Net Proceeds Offer Amount”) or, if less than the Net Proceeds Offer Amount has been so validly tendered, all Notes and Pari Passu Indebtedness validly tendered in response to the Net Proceeds Offer.

(e) If the Net Proceeds Purchase Date is on or after an interest record date and on or before the related interest payment date, any accrued and unpaid interest will be paid to the Person in whose name a Note is registered at the close of business on such record date, and no additional interest will be payable to Holders who tender Notes pursuant to the Net Proceeds Offer.

66

(f) Pending the final application of any Net Available Proceeds pursuant to this Section 4.10, the holder of such Net Available Proceeds may apply such Net Available Proceeds temporarily to reduce Indebtedness outstanding under a revolving Debt Facility or otherwise invest such Net Available Proceeds in any manner not prohibited by this Indenture.

(g) On or before the Net Proceeds Purchase Date, the Issuer will, to the extent lawful, accept for payment, on a pro rata basis to the extent necessary, the Net Proceeds Offer Amount of Notes and Pari Passu Indebtedness or portions of Notes and Pari Passu Indebtedness so validly tendered and not properly withdrawn pursuant to the Net Proceeds Offer, or if less than the Net Proceeds Offer Amount has been validly tendered and not properly withdrawn, all Notes and Pari Passu Indebtedness so validly tendered and not properly withdrawn, in each case in minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof. The Issuer or the Paying Agent, as the case may be, will promptly (but in any case not later than five Business Days after termination of the Net Proceeds Offer Period) mail or deliver to each tendering Holder and the Issuer will mail or deliver to each tendering holder or lender of Pari Passu Indebtedness, as the case may be, an amount equal to the purchase price of the Notes or Pari Passu Indebtedness so validly tendered and not properly withdrawn by such holder or lender, as the case may be, and accepted by the Issuer for purchase, and the Issuer will promptly issue a new Note, and the Trustee, upon delivery of an Officers’ Certificate from the Issuer, in form and substance reasonably satisfactory to the Trustee, will authenticate and mail or deliver such new Note to such Holder, in a principal amount equal to any unpurchased portion of the Note surrendered; provided that each such new Note will be in a minimum principal amount of $2,000 or an integral multiple of $1,000 in excess thereof. Any Note not so accepted will be promptly mailed or delivered by the Issuer to the Holder thereof. The Issuer shall publicly announce the results of the Net Proceeds Offer as soon as practicable after the Net Proceeds Purchase Date.

(h) Notwithstanding the foregoing provisions of this Section 4.10, the sale, conveyance or other disposition of all or substantially all of the assets of the Issuer and its Restricted Subsidiaries, taken as a whole, shall be governed by Section 4.13 and/or Section 5.1 and not by this Section 4.10.

(i) The Issuer shall comply with all applicable securities laws and regulations in the United States, including, without limitation, the requirements of Rule 14e-1 under the Exchange Act and any other applicable laws and regulations in connection with the purchase of Notes pursuant to a Net Proceeds Offer. To the extent that the provisions of any applicable securities laws or regulations conflict with this Section 4.10, the Issuer shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 4.10 by virtue of such compliance.

Section 4.11. Limitation on Transactions with Affiliates.

(a) The Issuer shall not, and shall not permit any of its Restricted Subsidiaries to, directly or indirectly, in one transaction or a series of related transactions, sell, lease, transfer or otherwise dispose of any of its assets to, or purchase any assets from, or enter into any contract, agreement, understanding, loan, advance or guarantee with, or for the benefit of, any Affiliate (an “Affiliate Transaction”) involving aggregate payments or consideration to or from the Issuer or a Restricted Subsidiary in excess of $15.0 million with respect to any single transaction or series of related transactions, unless:

(1) the terms of such Affiliate Transaction either (i) are not materially less favorable to the Issuer or such Restricted Subsidiary, as the case may be, than those that could reasonably be expected to have been obtained in a comparable transaction at the time of such transaction in arm’s length dealings with a Person who is not such an Affiliate, or (ii) if in the good faith judgment of the Issuer’s Board of Directors or senior management no comparable transaction is available with which to compare such Affiliate Transaction, are otherwise fair to the Issuer or such Restricted Subsidiary from a financial point of view; and

67

(2) the Issuer delivers to the Trustee, (i) with respect to any Affiliate Transaction involving aggregate value in excess of $25.0 million, an Officers’ Certificate certifying that such Affiliate Transaction complies with clause (a)(1) above and (ii) with respect to any Affiliate Transaction involving aggregate value in excess of $50.0 million, an Officers’ Certificate certifying that such Affiliate Transaction complies with clause (a)(1) above and which sets forth and authenticates a resolution that has been approved by the Board of Directors of the Issuer, including a majority of the disinterested members of the Board of Directors of the Issuer, if any.

(b) Notwithstanding the foregoing, Section 4.11(a) shall not prohibit:

(1) transactions to the extent between or among (i) the Issuer and one or more Restricted Subsidiaries or (ii) Restricted Subsidiaries;

(2) reasonable director, trustee, officer, consultant and employee compensation (including bonuses) and other benefits (including pursuant to any employment agreement or any retirement, health, stock option or other benefit plan), payments or loans (or cancellation of loans) to directors, trustees, officers, consultants and employees of the Issuer and indemnification arrangements, in each case, as determined in good faith by the Issuer’s Board of Directors or senior management;

(3) Permitted Investments or Restricted Payments which are made in accordance with Section 4.7;

(4) transactions pursuant to any agreement in effect on the Issue Date or as thereafter amended or replaced in any manner that, taken as a whole, is not materially less advantageous to the Issuer or its Restricted Subsidiaries than such agreement as it was in effect on the Issue Date;

(5) any transaction with a Person (other than an Unrestricted Subsidiary of the Issuer) which would constitute an Affiliate of the Issuer solely because the Issuer or a Restricted Subsidiary owns an equity interest in or otherwise controls such Person;

(6) transactions with customers, clients, suppliers, contractors, joint venture partners or purchasers or sellers of goods or services, or transactions otherwise related to the purchase or sales of goods or services, in each case in the ordinary course of business and otherwise not in violation of the terms of this Indenture; provided that in the reasonable determination of the Board of Directors of the Issuer or the senior management of the Issuer, such transactions are fair to the Issuer and its Restricted Subsidiaries from a financial point of view or on terms not materially less favorable to the Issuer or the relevant Restricted Subsidiary than those that could reasonably be expected to be obtained in a comparable transaction at such time on an arm’s-length basis from a Person that is not an Affiliate of the Issuer;

(7) the issuance or sale of any Qualified Equity Interests of the Issuer and the granting of registration, indemnification and other customary rights in connection therewith to, or the receipt of capital contributions from, Affiliates of the Issuer;

(8) payments to an Affiliate in respect of the Notes or any other Indebtedness of the Issuer or any of its Restricted Subsidiaries on a similar basis as concurrent payments are made or offered to be made in respect thereof to non-Affiliates;

(9) any transaction in which the Issuer or any of its Restricted Subsidiaries, as the case may be, delivers to the Trustee a letter from an accounting, appraisal or investment banking firm of national standing stating that such transaction is fair to the Issuer or such Restricted Subsidiary from a financial point of view or that such transaction meets the requirements of Section 4.11(a)(1);

68

(10) any transaction where the only consideration paid by the Issuer or the relevant Restricted Subsidiary is Qualified Equity Interests of the Issuer;

(11) transactions between the Issuer or any Restricted Subsidiary and any Person, a director of which is also a director of the Issuer or any direct or indirect parent company of the Issuer, and such director is the sole cause for such Person to be deemed an Affiliate of the Issuer or any Restricted Subsidiary; provided, however, that such director shall abstain from voting as a director of the Issuer or such direct or indirect parent company, as the case may be, on any matter involving such other Person;

(12) the entering into of a tax sharing agreement, or payments pursuant thereto, between the Issuer and/or one or more Subsidiaries, on the one hand, and any other Person with which the Issuer or such Subsidiaries are required or permitted to file a consolidated tax return or with which the Issuer or such Subsidiaries are part of a consolidated group for tax purposes to be used by such Person to pay taxes, and which payments by the Issuer and the Restricted Subsidiaries are not in excess of the tax liabilities that would have been payable by them on a stand-alone basis;

(13) Intellectual Property licenses in the ordinary course of business or consistent with industry practice; and

(14) (A) pledges and other transfers of Equity Interests in Unrestricted Subsidiaries and (B) any transactions with an Affiliate in which the consideration paid consists solely of Equity Interests of the Issuer.

Section 4.12. Limitation on Liens.

(a) The Issuer shall not, and shall not permit any Restricted Subsidiary to, directly or indirectly, create, incur, assume or permit or suffer to exist any Lien (an “Initial Lien”) of any kind (other than Permitted Liens) upon any of their property or assets (including Equity Interests of any Restricted Subsidiary), whether owned at the Issue Date or thereafter acquired, which Lien secures Indebtedness, unless contemporaneously with the incurrence of such Lien:

(1) in the case of any Lien securing Indebtedness that is not Subordinated Indebtedness, effective provision is made to secure the Notes or such Guarantee, as the case may be, at least equally and ratably with or prior to such Indebtedness with a Lien on the same collateral; and

(2) in the case of any Lien securing Subordinated Indebtedness, effective provision is made to secure the Notes or such Guarantee, as the case may be, with a Lien on the same collateral that is senior to the Lien securing such Subordinated Indebtedness.

(b) A Lien created for the benefit of the Holders pursuant to Section 4.12(a) shall provide by its terms that such Lien shall be automatically and unconditionally released and discharged upon the release and discharge of the Initial Lien. In addition, in the event that an Initial Lien is or becomes a Permitted Lien, the Issuer may, at its option and without consent from any Holder of the Notes, elect to release and discharge any Lien created for the benefit of the Holders of the Notes pursuant to Section 4.12(a) in respect of such Initial Lien.

69

Section 4.13. Offer to Purchase upon Change of Control Triggering Event.

(a) Upon the occurrence of any Change of Control Triggering Event, unless the Issuer has previously or concurrently exercised its right to redeem all of the Notes as described under Section 3.7, each Holder shall have the right, except as provided below, to require that the Issuer purchase all or any portion (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of that Holder’s Notes for a cash price (the “Change of Control Purchase Price”) equal to 101.0% of the principal amount of the Notes to be purchased, plus accrued and unpaid interest thereon, if any, to, but excluding, the date of purchase.

(b) Not later than 30 days following any Change of Control Triggering Event, the Issuer shall deliver, or cause to be delivered, to the Holders, with a copy to the Trustee, a notice:

(1) describing the transaction or transactions that constitute the Change of Control;

(2) offering to purchase, pursuant to the procedures required by this Indenture and described in the notice (a “Change of Control Offer”), on a date specified in the notice, which shall be a Business Day not earlier than 30 days, nor later than 60 days, from the date the notice is delivered (the “Change of Control Payment Date”), and for the Change of Control Purchase Price, all Notes properly tendered by such Holder pursuant to such Change of Control Offer prior to 5:00 p.m. New York time on the second Business Day preceding the Change of Control Payment Date; and

(3) describing the procedures, as determined by the Issuer, consistent with this Indenture, that Holders must follow to accept the Change of Control Offer.

(1) deposit with the Paying Agent an amount equal to the Change of Control Purchase Price in respect of all Notes or portions of Notes properly tendered;

(e) If the Change of Control Payment Date is on or after an interest record date and on or before the related interest payment date, any accrued and unpaid interest, if any, will be paid on the relevant interest payment date to the Person in whose name a Note is registered at the close of business on such record date.

(f) A Change of Control Offer shall remain open for at least 20 Business Days or for such longer period as is required by law. The Issuer shall publicly announce the results of the Change of Control Offer on or as soon as practicable after the Change of Control Payment Date.

70

(g) The Issuer shall not be required to make a Change of Control Offer upon a Change of Control Triggering Event if (i) a third party makes the Change of Control Offer in the manner, at the times and otherwise in compliance with the requirements set forth in this Indenture applicable to a Change of Control Offer made by the Issuer and purchases all Notes properly tendered and not withdrawn under such Change of Control Offer, (ii) in connection with or in contemplation of any publicly announced Change of Control, the Issuer has made an offer to purchase (an “Alternate Offer”) any and all Notes validly tendered at a cash price equal to or higher than the Change of Control Purchase Price and has purchased all Notes properly tendered in accordance with the terms of the Alternate Offer or (iii) a notice of redemption of all outstanding Notes has been given pursuant to Section 3.3, unless and until there is a default in the payment of the redemption price on the applicable redemption date or the redemption is not consummated due to the failure of a condition precedent contained in the applicable redemption notice to be satisfied.

(h) If Holders of not less than 90.0% in aggregate principal amount of the outstanding Notes validly tender and do not withdraw such Notes in a Change of Control Offer or Alternate Offer and the Issuer, or any third party making a Change of Control Offer in lieu of the Issuer as described above, purchases all of the Notes validly tendered and not withdrawn by such Holders, the Issuer will have the right, upon not less than 10 nor more than 60 days’ prior notice, given not more than 30 days following such purchase pursuant to the Change of Control Offer or an Alternate Offer, as applicable, to redeem all Notes that remain outstanding following such purchase at a redemption price in cash equal to the applicable Change of Control Purchase Price or an Alternate Offer price, as applicable, plus, to the extent not included in the Change of Control Purchase Price or an Alternate Offer price, as applicable, accrued and unpaid interest, if any, to, but excluding, the date of redemption.

(i) The Issuer shall comply with all applicable securities legislation in the United States, including, without limitation, the requirements of Rule 14e- 1 under the Exchange Act and any other applicable laws and regulations in connection with the purchase of Notes pursuant to a Change of Control Offer. To the extent that the provisions of any applicable securities laws or regulations conflict with this Section 4.13, the Issuer shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under this Section 4.13 by virtue of such compliance.

(j) The provisions under this Indenture relating to the Issuer’s obligation to make a Change of Control Offer may be waived, modified or terminated with the written consent of the Holders of a majority in principal amount of the Notes then outstanding.

(k) Notwithstanding anything to the contrary contained in this Section 4.13, a Change of Control Offer may be made in advance of a Change of Control Triggering Event, conditional upon such Change of Control Triggering Event or other events or circumstances, if a definitive agreement is in place for the Change of Control at the time of making of the Change of Control Offer.

Section 4.14. Corporate Existence. Subject to Article V, the Issuer shall do or cause to be done all things necessary to preserve and keep in full force and effect its corporate existence and the corporate, partnership, limited liability company or other existence of each of the Guarantors in accordance with the respective organizational or constitutional documents (as the same may be amended from time to time) of the Issuer or any such Guarantor and the rights (charter and statutory), licenses and franchises of the Issuer and the Guarantors; provided that the Issuer shall not be required to preserve any such right, license or franchise, or the corporate, partnership or other existence of any of the Guarantors, if the Issuer shall determine that the preservation thereof is no longer desirable in the conduct of the business of the Issuer and its Subsidiaries, taken as a whole, and that the loss thereof is not adverse in any material respect to the Holders.

Section 4.15. Additional Guarantees. If any Restricted Subsidiary of the Issuer that is not already a Guarantor shall guarantee any Indebtedness of the Issuer or any Guarantor under the (i) RCF Credit Agreement or (ii) any Debt Facility or capital markets debt securities of the Issuer or any Guarantor, in each case of this clause (ii), in an aggregate principal amount that exceeds the greater of (x) $50.0 million and (y) 1.0% of the Issuer’s Consolidated Total Assets, then the Issuer shall, within 30 days thereof, cause such Restricted Subsidiary to execute and deliver to the Trustee a supplemental indenture in substantially the form attached hereto as Exhibit B pursuant to which such Restricted Subsidiary shall become a Guarantor with respect to the Notes, upon the terms and subject to the release provisions and other limitations set forth in Article X.

Section 4.16. Limitation on Designation of Unrestricted Subsidiaries.

(a) The Board of Directors of the Issuer may designate any Subsidiary (including any newly formed or newly acquired Subsidiary or a Person becoming a Subsidiary through merger or consolidation or Investment therein) of the Issuer as an “Unrestricted Subsidiary” under this Indenture (a “Designation”) only if:

(1) no Default shall have occurred and be continuing at the time of or after giving effect to such Designation; and

(2) the Issuer would be permitted to make, at the time of such Designation, (a) a Permitted Investment or (b) an Investment pursuant to Section 4.7, in either case, in an amount (the “Designation Amount”) equal to the Fair Market Value of the Issuer’s proportionate interest in such Subsidiary on such date.

(b) No Subsidiary shall be Designated as an “Unrestricted Subsidiary” unless:

(1) all of the Indebtedness of such Subsidiary and its Subsidiaries shall, at the date of Designation, consist of Non-Recourse Debt, except for (i) any guarantee given solely to support the pledge by the Issuer or any Restricted Subsidiary of the Equity Interests of such Unrestricted Subsidiary, which guarantee is not otherwise recourse to the Issuer or any Restricted Subsidiary, (ii) any customary keepwell in the ordinary course of business (which keepwell is not recourse to the Issuer or any Restricted Subsidiary) and (iii) any guarantee of Indebtedness of such Subsidiary by the Issuer or a Restricted Subsidiary that is permitted as both an incurrence of Indebtedness and an Investment (in each case in an amount equal to the amount of such Indebtedness so guaranteed) permitted under Section 4.7 and Section 4.9;

(2) except as permitted by Section 4.11, on the date such Subsidiary is Designated an Unrestricted Subsidiary, such Subsidiary is not party to any agreement, contract, arrangement or understanding (other than a guarantee permitted under clause (1) of this Section 4.16(b)) with the Issuer or any Restricted Subsidiary unless the terms of the agreement, contract, arrangement or understanding are not materially less favorable to the Issuer or the Restricted Subsidiary than those that could reasonably be expected to have been obtained at the time from Persons who are not Affiliates of the Issuer; and

(3) such Subsidiary is a Person with respect to which neither the Issuer nor any of its Restricted Subsidiaries has any direct or indirect obligation (a) to subscribe for additional Equity Interests of such Person or (b) to maintain or preserve the Person’s financial condition or to cause the Person to achieve any specified levels of operating results (in each case other than a guarantee permitted under clause (1) of this Section 4.16(b)) or to the extent treated as an Investment permitted by Section 4.7.

72

Any such Designation by the Board of Directors of the Issuer shall be evidenced to the Trustee by filing with the Trustee a resolution of the Board of Directors of the Issuer giving effect to such Designation and an Officers’ Certificate certifying that such Designation complies with the foregoing conditions. If, at any time, any Unrestricted Subsidiary fails to meet the preceding requirements as an Unrestricted Subsidiary, it shall thereafter cease to be an Unrestricted Subsidiary for purposes of this Indenture and any Indebtedness of the Subsidiary and any Liens on assets of such Subsidiary shall be deemed to be incurred by a Restricted Subsidiary at such time and, if the Indebtedness is not permitted to be incurred under Section 4.9 or the Lien is not permitted under Section 4.12, the Issuer shall be in default of the applicable covenant.

(c) The Board of Directors of the Issuer may redesignate an Unrestricted Subsidiary as a Restricted Subsidiary (a “Redesignation”) only if:

(1) no Default shall have occurred and be continuing at the time of and after giving effect to such Redesignation; and

(2) all Liens, Indebtedness and Investments of such Unrestricted Subsidiary outstanding immediately following such Redesignation would, if incurred or made at such time, have been permitted to be incurred or made for all purposes of this Indenture.

Any such Redesignation shall be evidenced to the Trustee by filing with the Trustee an Officers’ Certificate certifying that such Redesignation complies with the foregoing conditions.

Section 4.17. Effectiveness of Covenants.

(a) If:

(1) the Notes have a Specified Investment Grade Rating from any two of the Rating Agencies; and

(2) no Default or Event of Default has occurred and is then continuing;

then upon delivery by the Issuer to the Trustee of an Officers’ Certificate to the foregoing effect (the date of delivery of any such Officers’ Certificate, the “Termination Date”), the Issuer and its Restricted Subsidiaries will thereafter, not be subject to the following covenants:

(i) Section 4.7;

(ii) Section 4.8;

(iii) Section 4.9;

(iv) Section 4.10;

(v) Section 4.11;

(vi) Section 4.15;

(vii) Section 4.16; and

(viii) Section 5.1(a)(3).

73

The Trustee shall have no duty to monitor the ratings of the Notes, shall not be deemed to have

knowledge of the ratings of the Notes and may conclusively rely on any Officer’s Certificate provided by the Issuer with respect to the ratings of the Notes. The Trustee shall have no duty to notify the Holders whether the Issuer and its Restricted Subsidiaries are subject to the provisions listed in this Section 4.17(a).

(b) Each Guarantor shall be automatically released from its obligations under its Guarantee and its obligations under this Indenture upon delivery by the Issuer to the Trustee of the Officers’ Certificate under Section 4.17(a) on the Termination Date.

(c) Following delivery by the Issuer to the Trustee of the Officers’ Certificate under Section 4.17(a) on the Termination Date, and solely for the purposes of determining compliance with Section 4.12 (i) notwithstanding the termination of Section 4.9 the ratio based exceptions, thresholds and basket provisions of such Section 4.9 that are referred to in, or necessary to give effect to, Section 4.12 shall be deemed to still be in effect and (ii) references to “Restricted Subsidiaries” shall be deemed to be references to “Subsidiaries,” as the context requires.

(d) The Trustee shall have no obligation to independently determine or verify if a Termination Date has occurred or notify the Holders of any Termination Date. The Trustee may provide a copy of such Officers’ Certificate to any Holder of the Notes upon request.

Section 4.18. Maintenance of Listing. The Issuer shall use its commercially reasonable efforts to obtain and maintain the listing of the Notes on the Official List of the International Stock Exchange (the “Exchange”) for so long as any Notes are outstanding; provided that if the Issuer is unable to obtain admission to listing of the Notes on the Exchange or if at any time the Issuer is unable to maintain such listing, it shall use its commercially reasonable efforts to obtain a listing of the Notes on another recognized stock exchange.

(5) default by the Issuer or any Restricted Subsidiary under any mortgage, indenture or other instrument or agreement under which there is issued or by which there is secured or evidenced Indebtedness for borrowed money by the Issuer or any Restricted Subsidiary, whether such Indebtedness now exists or is incurred after the Issue Date, which default:

(A) is caused by a failure to pay at its Stated Maturity principal on such Indebtedness within the applicable express grace period and any extensions thereof, or

76

(B) results in the acceleration of such Indebtedness prior to its Stated Maturity,

and, in each case, the principal amount of such Indebtedness, together with the principal amount of any other Indebtedness with respect to which an event described in clause (A) or (B) has occurred and is continuing, aggregates $100.0 million or more, and in any such case, such Indebtedness is not repaid or such failure to pay is not cured or such acceleration is not rescinded, annulled or otherwise cured within 30 days;

77

Section 6.2. Acceleration. If an Event of Default (other than an Event of Default specified in Section 6.1(7) with respect to the Issuer) shall have occurred and be continuing under this Indenture, the Trustee, by written notice to the Issuer, or the Holders of at least 25.0% in aggregate principal amount of the Notes then outstanding by written notice to the Issuer and the Trustee, may declare (an “acceleration declaration”) all amounts owing under the Notes to be due and payable. Upon such acceleration declaration, the aggregate principal of and accrued and unpaid interest on the outstanding Notes shall become due and payable immediately; provided, however, that after such acceleration, but before a judgment or decree based on acceleration, the Holders of a majority in aggregate principal amount of the Notes then outstanding may rescind and annul such acceleration if:

(1) the rescission would not conflict with any judgment or decree;

(2) all Events of Default have been cured or waived other than nonpayment of accelerated principal and interest;

(3) to the extent the payment of such interest is lawful, interest on overdue installments of interest and overdue principal, which has become due otherwise than by such declaration of acceleration, has been paid; and

(4) the Issuer has paid the Trustee its reasonable compensation and reimbursed the Trustee for its reasonable expenses, disbursements and advances.

No such rescission shall affect any subsequent Default or impair any right consequent thereto.

If an Event of Default specified in Section 6.1(7) occurs with respect to the Issuer, then all unpaid principal of and accrued and unpaid interest, if any, on all outstanding Notes shall ipso facto become and be immediately due and payable without any declaration, further action or notice to the extent permitted by applicable law.

Section 6.3. Other Remedies. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy to collect the payments on the Notes or to enforce the performance of any provision of the Notes or this Indenture.

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

Section 6.4. Waiver of Past Defaults. Subject to Section 9.2, the Holders of a majority in aggregate principal amount of the Notes then outstanding by written notice to the Trustee may, on behalf of the Holders of all of the Notes, waive any existing Default and its consequences under this Indenture except a continuing Default in the payment of interest or premium, or the principal of, the Notes.

Section 6.5. Control by Majority. The Holders of a majority in aggregate principal amount of the then outstanding Notes may direct the time, method and place of conducting any proceeding for exercising any remedy available to the Trustee or exercising any trust power conferred on it. However, (i) the Trustee may refuse to follow any direction that conflicts with law or this Indenture, that may involve the Trustee in personal liability, or that the Trustee determines in good faith may be unduly prejudicial to the rights of Holders not joining in the giving of such direction (it being understood that the Trustee does not have an affirmative duty to determine whether or not any such direction is unduly prejudicial to the

78

rights of Holders of the Notes not joining in the giving of such direction) and (ii) the Trustee may take any other action it deems proper that is not inconsistent with any such direction received from the Holders. Subject to Section 7.1, prior to taking any action hereunder, the Trustee shall be entitled to indemnification reasonably satisfactory to it against all loss, liability and expense caused by taking or not taking such action.

Section 6.6. Limitation on Suits. A Holder may pursue a remedy with respect to this Indenture or the Notes only if:

(1) the Holder gives the Trustee written notice of a continuing Event of Default;

(2) the Holder or Holders of at least 25.0% in aggregate principal amount of outstanding Notes make a written request to the Trustee to pursue the remedy;

(3) such Holder or Holders offer the Trustee indemnity satisfactory to the Trustee against any costs, liability or expense;

(4) the Trustee does not comply with the request within 60 days after receipt of the request and the offer of indemnity; and

(5) during such 60-day period, the Holders of a majority in aggregate principal amount of the outstanding Notes do not give the Trustee a direction that is 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 any such use by a Holder prejudices the rights of any other Holders or obtains priority or preference over such other Holders).

Section 6.7. Rights of Holders of Notes to Receive Payment. Notwithstanding any other provision of this Indenture, the contractual right of any Holder to receive payment of principal of, premium, if any, or interest on, such Note or to bring suit for the enforcement of any such payment, on or after the due date expressed in the Notes, shall not be modified without the consent of the Holder.

Section 6.8. Collection Suit by Trustee. If an Event of Default specified in Section 6.1(1) or Section 6.1(2) occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Issuer for the whole amount of principal of, premium and interest remaining unpaid on the Notes and interest on overdue principal and, to the extent lawful, such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel.

Section 6.9. Trustee May File Proofs of Claim. The Trustee is authorized to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and the Holders allowed in any judicial proceedings relative to the Issuer (or any other obligor upon the Notes), its creditors or its property and shall be entitled and empowered to collect, receive and distribute any money or other securities or property payable or deliverable upon the conversion or exchange of the Notes or on any such claims, and any custodian in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee under Section 7.6. To the extent that the payment of any such compensation, expenses, disbursements and advances to the Trustee, its agents and counsel,

79

and any other amounts due the Trustee under Section 7.6 out of the estate in any such proceeding, shall be denied for any reason, payment of the same shall be secured by a Lien on, and shall be paid out of, any and all distributions, dividends, money, securities and other properties that the Holders may be entitled to receive in such proceeding, whether in liquidation or under any plan of reorganization or arrangement or otherwise. Nothing in this Section 6.9 shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Notes or the rights of any Holder, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

Section 6.10. Priorities. If the Trustee collects any money or property pursuant to this Article VI, it shall pay out the money and property in the following order:

First: to the Trustee, its agents and attorneys for amounts due under Section 7.6, including payment of all reasonable compensation, expenses and liabilities incurred, and all advances made, by it and the costs and expenses of collection;

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

Third: without duplication, to the Holders for any other Obligations owing to the Holders under this Indenture and the Notes; and

Fourth: to the Issuer or to such party as a court of competent jurisdiction shall direct.

The Trustee may fix a record date and payment date for any payment to Holders pursuant to this Section 6.10.

Section 6.11. 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 the 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 and expenses, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.7, or a suit by Holders of more than 10.0% in principal amount of the then outstanding Notes.

Section 6.12. Noteholder Direction.

(a) Any notice of Default, notice of acceleration or instruction to the Trustee to provide a notice of Default, notice of acceleration or take any other action (a “Noteholder Direction”) provided by any one or more Holders of Notes (except any Holder that certifies in the Noteholder Direction that it is a Regulated Bank) (each a “Directing Holder”) must be accompanied by a written representation from each such Holder of Notes delivered to the Issuer and the Trustee that such Holder of Notes is not (or, in the case such Holder of Notes is DTC or its nominee, that such Holder of Notes is being instructed solely by beneficial owners that are not) Net Short (a “Position Representation”), which representation, in the case of a Noteholder Direction relating to the delivery of a notice of Default shall be deemed a continuing representation until the resulting Event of Default is cured or otherwise ceases to exist or the Notes are accelerated. In addition, each Directing Holder is deemed, at the time of providing a Noteholder Direction, to covenant to provide the Issuer with such other information as the Issuer may reasonably request from time to time in order to verify the accuracy of such Holder’s Position Representation within five Business Days of request therefor

80

(a “Verification Covenant”). In any case in which the Holder of Notes is DTC or its nominee, any Position Representation or Verification Covenant required hereunder shall be provided by the beneficial owner of the Notes in lieu of DTC or its nominee, and DTC shall be entitled to rely conclusively on such Position Statement and Verification Covenant in delivering its direction to the Trustee.

(b) If, following the delivery of a Noteholder Direction, but prior to acceleration of the Notes, the Issuer determines in good faith that there is a reasonable basis to believe a Directing Holder was, at any relevant time, in breach of its Position Representation and provides to the Trustee an Officers’ Certificate stating that the Issuer has initiated litigation in a court of competent jurisdiction seeking a determination that such Directing Holder was, at such time, in breach of its Position Representation, and seeking to invalidate any Event of Default that resulted from the applicable Noteholder Direction, the cure period with respect to such Default shall be automatically stayed and the cure period with respect to such Event of Default shall be automatically reinstituted and any remedy stayed pending a final and non-appealable determination of a court of competent jurisdiction on such matter if, without the participation of such Holder, the percentage of Notes held by the remaining Holders that provided such Noteholder Direction would have been insufficient to validly provide such Noteholder Direction. If, following the delivery of a Noteholder Direction, but prior to acceleration of the Notes, the Issuer provides to the Trustee an Officers’ Certificate stating that a Directing Holder failed to satisfy its Verification Covenant, the cure period with respect to such Default shall be automatically stayed and the cure period with respect to any Event of Default that resulted from the applicable Noteholder Direction shall be automatically reinstituted and any remedy stayed pending satisfaction of such Verification Covenant. Any breach of the Position Representation shall result in such Holder’s participation in such Noteholder Direction being disregarded; and, if, without the participation of such Holder of Notes, the percentage of Notes held by the remaining Holders of Notes that provided such Noteholder Direction would have been insufficient to validly provide such Noteholder Direction, such Noteholder Direction shall be void ab initio, with the effect that such Event of Default shall be deemed never to have occurred, acceleration voided and the Trustee shall be deemed not to have received such Noteholder Direction or any notice of such Default or Event of Default; provided, however, such voiding of such Noteholder Direction shall not void or invalidate any indemnity or security provided by the Directing Holders to the Trustee, which such indemnification or security obligations shall continue to survive.

(c) Notwithstanding anything in Section 6.12(a) or Section 6.12(b) to the contrary, (i) any Noteholder Direction delivered to the Trustee during the pendency of an Event of Default as the result of a bankruptcy or similar proceeding shall not require compliance with Section 6.12(a) or Section 6.12(b) and (ii) a notice of Default may not be given with respect to any action taken, and reported publicly to Holders, more than two years prior to such notice of Default. In addition, for the avoidance of doubt, Section 6.12(a) and Section 6.12(b) shall not apply to any Holder of Notes that is a Regulated Bank and has so stated in the applicable Noteholder Direction. For the avoidance of doubt, (i) the Trustee shall be entitled to conclusively rely on any Noteholder Direction delivered to it in accordance with this Indenture, shall have no duty to inquire as to or investigate the accuracy of any Position Representation, enforce compliance with any Verification Covenant, verify any statements in any officer’s certificate delivered to it, or otherwise make calculations, investigations or determinations with respect to Derivative Instruments, Net Shorts, Long Derivative Instruments, Short Derivative Instruments or otherwise, (ii) shall have no obligation to monitor or to determine whether a Directing Holder is Net Short and (iii) can conclusively rely on a Directing Holder’s Position Representation, any Officer’s Certificate delivered by the Issuer to the Trustee and the determinations made by a court of competent jurisdiction. The Trustee shall have no liability to the Issuer, any Holder of Notes or any other Person in acting in good faith on a Noteholder Direction.

ARTICLE VII

TRUSTEE

Section 7.1. Duties of Trustee.

(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 its exercise as a prudent person would exercise or use under the circumstances in the conduct of his or her own affairs. The Trustee shall not be liable for any action taken or omitted by it in the performance of its duties under this Indenture except for its own gross negligence or willful misconduct.

(b)

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

(2) 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 (but need not confirm or investigate the accuracy of mathematical calculations or other facts stated therein); provided, however, in the case of any such certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall examine the certificates and opinions furnished to it to determine whether or not they conform to the requirements of this Indenture.

(c) The Trustee may not be relieved from liabilities for its own grossly negligent actions, its own grossly negligent failure to act, or its own willful misconduct, except that:

(1) this paragraph 7.1(c) does not limit the effect of paragraph 7.1(b), 7.1(d) or 7.1(e) or 7.2;

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

(3) the Trustee shall not be liable with respect to any action it takes or omits to take in accordance with a direction received by it pursuant to Section 6.5; and

(4) no provision of this Indenture shall require the Trustee to expend or risk its own funds or incur any liability.

(d) The Trustee shall not be liable for interest on or the investment of any money received by it except as the Trustee may agree in writing with the Issuer. Money held in trust by the Trustee need not be segregated from other funds except to the extent required by law. The Trustee shall have no investment discretion and the Trustee’s only responsibility for investments shall be to follow the written instructions of the Issuer. Absent written investment instructions, all moneys or deposits held by the Trustee shall be uninvested. The Trustee shall not incur any liability for losses arising from any investments made pursuant to this Indenture. The Trustee shall not be required to determine the suitability or legality of any investments.

82

(e) Whether or not therein expressly so provided, every provision of this Indenture that in any way relates to the Trustee is subject to Article VII.

Section 7.2. Rights of Trustee.

(a) The Trustee may conclusively rely and shall be fully protected in acting or refraining from acting on any resolution, certificate, statement, instrument, opinion, notice, report, request, direction, consent, order, bond, debenture or other document (whether in original or facsimile form) 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 therein.

(b) Before the Trustee acts or refrains from acting, it may require an Officers’ 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 Officers’ Certificate or Opinion of Counsel. Prior to taking, suffering or admitting any action, the Trustee may consult with counsel of the Trustee’s own choosing, and the Trustee shall be fully protected from liability in respect of any action taken, suffered or omitted by it hereunder in good faith and in conclusive reliance on the advice or opinion of such counsel.

(c) The Trustee may act through its attorneys and agents and shall not be responsible for the misconduct or negligence of any attorney or agent appointed with due care.

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

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

(f) The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request or direction of any of the Holders unless such Holders shall have offered to the Trustee security or indemnity satisfactory to the Trustee against the costs, expenses and liabilities that might be incurred by it in compliance with such request or direction.

(g) The Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or documents, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall be entitled to examine during normal business hours the books, records and premises of the Issuer, personally or by agent or attorney at the sole cost of the Issuer, and shall incur no liability or additional liability of any kind by reason of such inquiry or investigation.

(h) The rights, privileges, protections, immunities and benefits given to the Trustee, including, without limitation, its right to be indemnified, are extended to, and shall be enforceable by, the Trustee in each of its capacities hereunder, to the Agents and to each other agent, custodian and Person employed to act hereunder.

(i) The Trustee may request that the Issuer and each of the Guarantors shall deliver to the Trustee an Officers’ Certificate setting forth the names of individuals and/or titles of Officers of the Issuer and each Guarantor, as applicable, authorized at such time to take specified actions pursuant to this Indenture of the Issuer, the Notes and the Guarantees, which Officers’ Certificate may be signed by any Person authorized to sign an Officers’ Certificate, including any Person specified as so authorized in any such certificate previously delivered and not superseded.

83

(j) The Trustee shall not be deemed to have notice of any Default or Event of Default, unless a Responsible Officer of the Trustee has actual knowledge thereof or the Trustee shall have been notified specifically of the Default or Event of Default in a written instrument or document delivered to it, referring to this Indenture, describing such Event of Default and stating that such notice is a “Notice of Default.”

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

(l) The Trustee shall not be required to give any bond or surety in respect of the performance of its powers and duties hereunder.

(m) The Issuer will be responsible for making calculations called for under the Notes, including but not limited to determination of redemption price, premium, if any, and any other amounts payable on the Notes. The Issuer will make the calculations in good faith and, absent manifest error, its calculations will be final and binding on the Holders of the Notes. The Issuer will provide a schedule of its calculations to the Trustee when applicable, and the Trustee is entitled to rely conclusively on the accuracy of the Issuer’s calculations without independent verification.

(n) The permissive right of the Trustee to do things enumerated in this Indenture shall not be construed as a duty.

(o) In addition to all of the rights, benefits, privileges and immunities granted to the Trustee and Agents hereunder, and notwithstanding that this Indenture is not qualified under the TIA, all of the rights, benefits, privileges and immunities granted to a trustee under the TIA are incorporated herein.

Section 7.3. Individual Rights of the Trustee. The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Issuer or any Affiliate of the Issuer with the same rights it would have if it were not Trustee. Any Agent may do the same with like rights and duties. The Trustee is also subject to Section 7.9.

Section 7.4. Trustee’s Disclaimer. The Trustee shall not be responsible for and makes no representation as to the validity or adequacy of this Indenture, the Notes or any Guarantee, it shall not be accountable for the use of the proceeds from the Notes or any money paid to the Issuer or upon the Issuer’s direction under any provision of this Indenture, 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 Notes, any Officers’ Certificate delivered to the Trustee hereunder, or any other document in connection with the sale of the Notes or pursuant to this Indenture other than the Trustee’s certificate of authentication hereunder.

Section 7.5. Notice of Defaults. If a Default or Event of Default occurs and is continuing and if a Responsible Officer of the Trustee has knowledge thereof as set forth in Section 7.2(j), the Trustee shall deliver to Holders a notice of the Default or Event of Default within 90 days after it occurs. Except in the case of a Default or Event of Default in payment of principal of, premium, if any, or interest on any Note, the Trustee may withhold the notice if and so long as the board of directors, the executive committee or a trust committee of directors or Responsible Officers of the Trustee in good faith determines that the withholding of such notice is in the interest of the Holders.

84

Section 7.6. Compensation and Indemnity. The Issuer shall pay to the Trustee from time to time compensation for its acceptance of this Indenture and for all services rendered by it hereunder as agreed upon in writing; including but not limited to acting as Registrar or Paying Agent. The Trustee’s compensation shall not be limited by any law on compensation of a trustee of an express trust. The Issuer shall reimburse the Trustee, as applicable, promptly upon request for all reasonable disbursements, advances and expenses incurred or made by it in addition to the compensation for its services. Such expenses shall include the reasonable compensation, disbursements and expenses of the Trustee’s agents and counsel.

Each of the Issuer and the Guarantors, jointly and severally, shall indemnify, defend, protect and hold harmless the Trustee (in its individual and trustee capacities or in its capacity as Registrar or Paying Agent) and its officers, directors, employees and agents from and against any and all claims, damages, losses, liabilities, actions, suits, costs or expenses incurred by it (including, without limitation, the fees and expenses of its agents and counsel and court costs) arising out of or in connection with the acceptance or administration of its duties under this Indenture and trusts thereunder, the performance of its obligations and/or exercise of its rights hereunder, including the costs and expenses of enforcing this Indenture against the Issuer or any Guarantor (including this Section 7.6) and defending itself against any claim (whether asserted by the Issuer or any Holder or any other Person) or liability in connection with the exercise or performance of any of its powers or duties hereunder, except to the extent any such loss, claim, damage, liability or expense shall be caused by its own gross negligence or willful misconduct as determined by a court of competent jurisdiction in a final, non-appealable judgment. The Trustee shall notify the Issuer promptly of any claim for which it may seek indemnity. Failure by the Trustee to so notify the Issuer shall not relieve the Issuer of its obligations hereunder. The Trustee may have one separate counsel, and the Issuer shall pay the reasonable fees and expenses of such counsel for the Trustee. The Issuer need not pay for any settlement made without its consent, which consent shall not be unreasonably withheld. The liability of any Guarantor organized in Switzerland (a “Swiss Guarantor”) under this Section 7.6 shall be limited to such Swiss Guarantor’s Swiss Available Amount.

The obligations of the Issuer and the Guarantors under this Section 7.6 shall survive the satisfaction and discharge of this Indenture, the payment of the Notes or the resignation or removal of the Trustee.

To secure the Issuer’s payment obligations in this Section 7.6, the Trustee shall have a Lien prior to the Notes on all money or property held or collected by the Trustee, except that held in trust to pay principal or interest, if any, on particular Notes. Such Lien shall survive the satisfaction and discharge of this Indenture, the payment of the Notes and the resignation or removal of the Trustee.

When the Trustee incurs expenses or renders services after an Event of Default specified in Section 6.1(7) occurs, the expenses and the compensation for the services (including the fees and expenses of its agents and counsel) are intended to constitute expenses of administration under any Bankruptcy Law.

Section 7.7. 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 7.7.

The Trustee may resign in writing at any time and be discharged from the trust hereby created by so notifying the Issuer not less than 30 days prior to the effective date of such resignation. The Holders of a majority in principal amount of the then outstanding Notes may remove the Trustee upon 30 days’ prior notice by so notifying the Trustee and the Issuer in writing. The Issuer may remove the Trustee if:

(a) the Trustee fails to comply with Section 7.9;

85

(b) 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;

(c) a custodian or public officer takes charge of the Trustee or its property; or

(d) the Trustee becomes incapable of acting.

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

If a successor trustee does not take office within 30 days after the retiring Trustee resigns or is removed, such retiring Trustee (at the expense of the Issuer), the Issuer or the Holders of at least 10.0% in principal amount of the then outstanding Notes may petition any court of competent jurisdiction for the appointment of a successor trustee.

If the Trustee, after written request by any Holder who has been a bona fide holder of a Note for at least six months, fails to comply with Section 7.9, such 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 Issuer. Thereupon, the resignation or removal of the retiring Trustee shall become effective, and the successor trustee shall have all the rights, powers and the duties of the Trustee under this Indenture. The successor trustee shall mail a notice of its succession to the Holders. The retiring Trustee shall promptly transfer all property held by it as Trustee to the successor Trustee; provided that all sums owing to such Trustee hereunder have been paid and subject to the Lien provided for in Section 7.6. Notwithstanding replacement of the Trustee pursuant to this Section 7.7, the Issuer’s and the Guarantors’ obligations under Section 7.6 shall continue for the benefit of the retiring Trustee.

Section 7.8. Successor Trustee by Merger, Etc. If the Trustee or any Agent consolidates, merges or converts into, or transfers all or substantially all of its corporate trust business (including this transaction) to, another corporation, the successor corporation without any further act shall be the successor Trustee or any Agent, as applicable.

Section 7.9. Eligibility; Disqualification. There shall at all times be a Trustee hereunder that is a corporation organized and doing business under the laws of the United States or of any state thereof that is authorized under such laws to exercise corporate trustee power and that is subject to supervision or examination by federal or state authorities. Such Trustee together with its affiliates shall at all times have a combined capital surplus of at least $50.0 million as set forth in its most recent annual report of condition.

ARTICLE VIII

DEFEASANCE; DISCHARGE OF THIS INDENTURE

Section 8.1. Option to Effect Legal Defeasance or Covenant Defeasance. The Issuer may, by delivery of an Officers’ Certificate, at any time, elect to have either Section 8.2 or Section 8.3 applied to all outstanding Notes upon compliance with the conditions set forth below in this Article VIII.

86

Section 8.2. Legal Defeasance. Upon the Issuer’s exercise under Section 8.1 of the option applicable to this Section 8.2, the Issuer shall, subject to the satisfaction of the conditions set forth in Section 8.4, be deemed to have been discharged from its obligations with respect to all outstanding Notes on the date the conditions set forth below are satisfied (hereinafter, “Legal Defeasance”). For this purpose, Legal Defeasance means that the Issuer and the Guarantors shall be deemed to have paid and discharged the entire Obligations represented by the Notes and the Guarantees, which shall thereafter be deemed to be outstanding only for the purposes of Section 8.5 and the other Sections of this Indenture referred to in (a) and (b) below, and to have satisfied all of its other Obligations under such Notes, Guarantees and this Indenture (and the Trustee, on written demand of and at the expense of the Issuer, shall execute instruments acknowledging the same), and this Indenture shall cease to be of further effect as to all such Notes and Guarantees, except for the following provisions which shall survive until otherwise terminated or discharged hereunder: (a) the rights of Holders of outstanding Notes to receive payments in respect of the principal of, and interest and premium, if any, on such Notes when such payments are due from the trust funds referred to in Section 8.4(1); (b) the Issuer’s obligations with respect to such Notes under Section 2.2, Section 2.3, Section 2.4, Section 2.6, Section 2.7, Section 2.10, and Section 4.2; (c) the rights, powers, trusts, duties and immunities of the Trustee, including without limitation thereunder, under Section 7.2, Section 7.6, Section 8.5 and Section 8.7 and the obligations of the Issuer and the Guarantors in connection therewith; and (d) the provisions of this Article VIII. Subject to compliance with this Article VIII, the Issuer may exercise its option under this Section 8.2 notwithstanding the prior exercise of its option under Section 8.3.

Section 8.3. Covenant Defeasance. Upon the Issuer’s exercise under Section 8.1 above of the option applicable to this Section 8.3, the Issuer shall, subject to the satisfaction of the conditions set forth in Section 8.4 below, be released from its obligations under Section 4.3, Section 4.7, Section 4.8, Section 4.9, Section 4.10, Section 4.11, Section 4.12, Section 4.13, Section 4.15, Section 4.16 and Section 5.1(a)(3) on and after the date the conditions set forth below are satisfied (hereinafter, “Covenant Defeasance”), and the Notes shall thereafter be deemed not outstanding for the purposes of any direction, waiver, consent or declaration or act of Holders (and the consequences of any thereof) in connection with such covenants, but shall continue to be deemed outstanding for all other purposes hereunder (it being understood that such Notes shall not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes, the Issuer or any of its Subsidiaries may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document and such omission to comply shall not constitute a Default under Section 6.1, but, except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby.

Section 8.4. Conditions to Legal or Covenant Defeasance. The following shall be the conditions to the application of either Section 8.2 or Section 8.3 to the outstanding Notes:

(1) the Issuer must irrevocably deposit with the Trustee, as trust funds, in trust solely for the benefit of the Holders, U.S. dollars, U.S. Government Obligations or a combination thereof, in such amounts as will be sufficient (without consideration of any reinvestment of interest) in the opinion of a nationally recognized investment bank, appraisal firm or firm of independent public accountants selected by the Issuer and delivered and addressed to the Trustee, to pay the principal of and interest, if any, on the outstanding Notes on the stated date for payment thereof or on the applicable redemption date, as the case may be,

(2) in the case of Legal Defeasance, the Issuer shall have delivered to the Trustee an Opinion of Counsel from counsel in the United States confirming that:

(A) the Issuer has received from, or there has been published by, the United States Internal Revenue Service a ruling, or

87

(B) since the Issue Date, there has been a change in the applicable U.S. federal income tax law,

in either case to the effect that, and based thereon such Opinion of Counsel shall confirm that, the beneficial owners of the outstanding Notes will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such Legal Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Legal Defeasance had not occurred,

(3) in the case of Covenant Defeasance, the Issuer shall have delivered to the Trustee an Opinion of Counsel from counsel in the United States confirming that the beneficial owners of the outstanding Notes will not recognize income, gain or loss for U.S. federal income tax purposes as a result of such Covenant Defeasance and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Covenant Defeasance had not occurred,

(4) no Default shall have occurred and be continuing on the date of such deposit (other than a Default resulting from the borrowing of funds to be applied to such deposit and the grant of any Lien securing such borrowings),

(5) the Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under any other material agreement or instrument (other than this Indenture and the agreements governing any other Indebtedness being defeased, discharged or replaced) to which the Issuer or any of its Subsidiaries is a party or by which the Issuer or any of its Subsidiaries is bound,

(6) the Issuer shall have delivered to the Trustee an Officers’ Certificate stating that the deposit was not made by it with the intent of preferring the Holders over any other of its creditors or with the intent of defeating, hindering, delaying or defrauding any other of its creditors or others, and

(7) the Issuer shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel to the effect that the conditions precedent provided for in clauses (1) through (6) of this Section 8.4 have been complied with.

Section 8.5. Deposited Money and U.S. Government Obligations to Be Held in Trust; Other Miscellaneous Provisions. Subject to Section 8.6, all U.S. dollar and U.S. Government Obligations (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.5, the “Deposit Trustee”) pursuant to Section 8.4 or Section 8.8 in respect of the outstanding Notes shall be held in trust, shall not be invested, and shall be applied by the Deposit Trustee in accordance with the provisions of such Notes and this Indenture to the payment, either directly or through any Paying Agent (including the Issuer or any Subsidiary acting as Paying Agent) as the Deposit Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of principal, premium, if any, and interest, if any, but such money need not be segregated from other funds except to the extent required by law.

The Issuer shall pay and indemnify the Deposit Trustee against any tax, fee or other charge imposed on or assessed against the cash or non-callable U.S. Government Obligations deposited pursuant to Section 8.4 or Section 8.8 or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the outstanding Notes.

88

Anything in this Article VIII to the contrary notwithstanding, the Deposit Trustee shall deliver or pay to the Issuer from time to time upon the written request of the Issuer and be relieved of all liability with respect to any U.S. dollars or non-callable U.S. Government Obligations held by it as provided in Section 8.4 or Section 8.8 which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Deposit Trustee (which may be the opinion delivered under Section 8.4(1)), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance or satisfaction and discharge, as the case may be.

Section 8.6. Repayment to Issuer. Subject to any applicable abandoned property law, any money deposited with the Trustee or any Paying Agent, or then held by the Issuer, in trust for the payment of the principal of, premium, if any, or interest, if any, on any Note and remaining unclaimed for two years after such principal and premium, if any, or interest has become due and payable shall be paid to the Issuer on its written request or (if then held by the Issuer) shall be discharged from such trust; and the Holder of such Note shall thereafter, as an unsecured general creditor, look only to the Issuer for payment thereof; and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Issuer as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such repayment, may at the expense of the Issuer cause to be published once, in the New York Times and The Wall Street Journal (national edition), notice that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such notification or publication, any unclaimed balance of such money then remaining shall be repaid to the Issuer.

Section 8.7. Reinstatement. If the Trustee or Paying Agent is unable to apply any U.S. dollars or U.S. Government Obligations in accordance with Section 8.2, Section 8.3 or Section 8.8, as the case may be, by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the obligations of the Issuer and the Guarantors under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 8.2, Section 8.3 or Section 8.8 until such time as the Trustee or Paying Agent is permitted to apply all such money in accordance with Section 8.2, Section 8.3 or Section 8.8, as the case may be; provided, however, that, if the Issuer makes any payment of principal of, premium, if any, or interest on any Note following the reinstatement of its obligations, the Issuer shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or Paying Agent.

Section 8.8. Discharge. This Indenture will be discharged and will cease to be of further effect (except as to rights, protections and immunities of the Trustee) as to all outstanding Notes when either:

(1) all the Notes that have been authenticated and delivered (except lost, stolen or destroyed Notes which have been replaced or paid and Notes for whose payment money has been deposited in trust or segregated and held in trust by the Issuer and thereafter repaid to the Issuer or discharged from this trust), have been delivered to the Trustee for cancellation; or

(2) (A) all Notes not delivered to the Trustee for cancellation otherwise (i) have become due and payable, (ii) will become due and payable, or may be called for redemption, within one year or (iii) have been called for redemption pursuant to Section 3.7 and, in any case, the Issuer has irrevocably deposited or caused to be deposited with the Trustee as trust funds in trust solely for the benefit of the Holders, cash in U.S. dollars, U.S. Government Obligations or a combination thereof, in such amounts as will be sufficient without consideration of any reinvestment of interest (which in the case of a deposit of U.S. Government Obligations will be in the opinion of a nationally recognized investment bank, appraisal firm or firm of independent public accountants selected by the Issuer and delivered to the Trustee) to pay and discharge the entire Indebtedness (including all

89

principal and accrued interest, if any) on the Notes not theretofore delivered to the Trustee for cancellation (provided that if such redemption is made as provided under Section 3.7(a), (x) the amount of cash in U.S. dollars, non-callable Government Securities, or a combination thereof, that must be irrevocably deposited will be determined using an assumed Applicable Premium calculated as of the date of such deposit and (y) the depositor must irrevocably deposit or cause to be deposited additional money in trust on the redemption date as necessary to pay the Applicable Premium as determined by such date) (any such amount, the “Applicable Premium Deficit”) (it being understood that any satisfaction and discharge shall be subject to the condition subsequent that such Applicable Premium Deficit is in fact paid); provided that the Trustee shall have no liability whatsoever in the event that such Applicable Premium Deficit is not in fact paid after any satisfaction and discharge of this Indenture and that any Applicable Premium Deficit will be set forth in an Officers’ Certificate delivered to the Trustee simultaneously with the deposit of such Applicable Premium Deficit that confirms that such Applicable Premium Deficit will be applied toward such redemption);

(B) the Issuer has paid or caused to be paid all other sums payable by it under this Indenture; and

(C) the Issuer has delivered irrevocable instructions to the Trustee under this Indenture to apply the deposited money toward the payment of the Notes at maturity or on the date of redemption, as the case may be.

In addition, the Issuer must deliver an Officers’ Certificate and an Opinion of Counsel to the Trustee stating that all conditions precedent to satisfaction and discharge have been complied with.

After the Notes are no longer outstanding, the Issuer’s and the Guarantors’ obligations in Section 7.6, Section 8.5 and Section 8.7 shall survive any discharge pursuant to this Section 8.8.

After such delivery or irrevocable deposit and receipt of the Officers’ Certificate and Opinion of Counsel, the Trustee, upon written request, shall acknowledge in writing the discharge of the Issuer’s obligations under the Notes and this Indenture except for those surviving obligations specified above.

ARTICLE IX

(6) to secure the Notes or any Guarantees or any other obligation under this Indenture or effect the release of any collateral in respect thereof (to the extent in accordance with the provisions of this Indenture);

(7) to evidence and provide for the acceptance of appointment by a successor Trustee;

(8) to conform the text of this Indenture or the Notes to any provision of the “Description of notes” contained in the Offering Memorandum, to the extent that such provision in the “Description of notes” was intended to be a substantially verbatim recitation of a provision of this Indenture, the Guarantees or the Notes, as evidenced by an Officers’ Certificate of the Issuer;

(6) waive a default in the payment of principal of or premium or interest, if any, on any Notes (except a rescission of acceleration of the Notes by the Holders thereof as provided in this Indenture and a waiver of the payment default that resulted from such acceleration);

(7) modify the contractual rights of Holders to receive payments of principal of or interest or Additional Amounts, if any, on the Notes on or after the due date therefor or to institute suit for the enforcement of any payment on the Notes;

(8) release any Guarantor from any of its obligations under its Guarantee or this Indenture, except as permitted by this Indenture; or

(9) make any change in these amendment and waiver provisions.

It shall not be necessary for the consent of the Holders under this Section 9.2 to approve the particular form of any proposed amendment or waiver, but it shall be sufficient if such consent approves the substance thereof.

Section 9.3. Revocation and Effect of Consents. Until an amendment, supplement or waiver becomes effective, a consent to it by a Holder of a Note is a continuing consent by the Holder and every subsequent Holder of that Note or portion of the Note that evidences the same debt as the consenting Holder’s Note, even if notation of the consent is not made on the Note. However, any such Holder or subsequent Holder may revoke the consent as to its Note if the Trustee receives written notice of revocation before the date the waiver, supplement or amendment becomes effective. When an amendment, supplement or waiver becomes effective in accordance with its terms, it thereafter binds every Holder.

The Issuer may, but shall not be obligated to, fix a record date for determining which Holders consent to such amendment, supplement or waiver.

Section 9.4. Notation on or Exchange of Notes. The Trustee may place an appropriate notation about an amendment, supplement or waiver on any Note thereafter authenticated. The Issuer in exchange for all Notes may issue and the Trustee shall authenticate new Notes that reflect the amendment, supplement or waiver.

Failure to make the appropriate notation or issue a new Note shall not affect the validity and effect of such amendment, supplement or waiver.

92

Section 9.5. Trustee to Sign Amendments, Etc. The Trustee shall sign any amended or supplemental indenture authorized pursuant to this Article IX if the amendment or supplement does not adversely affect the rights, duties, liabilities or immunities of the Trustee. In signing or refusing to sign any amendment or supplemental indenture, the Trustee shall be provided with and (subject to Section 7.1) shall be fully protected in relying upon an Officers’ Certificate and an Opinion of Counsel stating that the execution of such amendment or supplemental indenture is authorized or permitted by this Indenture and that all conditions precedent thereto have been met or waived.

GUARANTEES

Section 10.1. Guarantees.

(a) Each Guarantor hereby jointly and severally, fully and unconditionally guarantees the Notes and obligations of the Issuer hereunder and thereunder, and guarantees to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee, that: (i) the principal of and premium, if any, and interest, if any, on the Notes shall be paid in full when due, whether at Stated Maturity, by acceleration, call for redemption or otherwise, together with interest on the overdue principal, if any, and interest on any overdue interest, if any, to the extent lawful, and all other Obligations of the Issuer to the Holders or the Trustee under this Indenture or the Notes shall be paid in full or performed, all in accordance with the terms hereof and thereof; and (ii) in case of any extension of time of payment or renewal of any Notes or of any such other obligations, the same shall be paid in full when due or performed in accordance with the terms of the extension or renewal, whether at Stated Maturity, by acceleration or otherwise. Each of the Guarantees shall be a guarantee of payment and not of collection.

(b) Each Guarantor hereby agrees that its obligations hereunder shall be unconditional, irrespective of the validity, regularity or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder with respect to any provisions hereof or thereof, the recovery of any judgment against the Issuer, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a Guarantor.

(c) Each Guarantor hereby waives the benefits of diligence, presentment, demand for payment, filing of claims with a court in the event of insolvency or bankruptcy of the Issuer, any right to require a proceeding first against the Issuer or any other Person, protest, notice and all demands whatsoever and covenants that the Guarantee of such Guarantor shall not be discharged as to any Note or this Indenture except by complete performance of the obligations contained in such Note and this Indenture and such Guarantee. Each of the Guarantors hereby agrees that, in the event of a Default in payment of principal or premium, if any, or interest on any Note, whether at its Stated Maturity, by acceleration, call for redemption, purchase or otherwise, legal proceedings may be instituted by the Trustee on behalf of, or by, the Holder of such Note, subject to the terms and conditions set forth in this Indenture, directly against each of the Guarantors to enforce each such Guarantor’s Guarantee without first proceeding against the Issuer or any other Guarantor. Each Guarantor agrees that if, after the occurrence and during the continuance of an Event of Default, the Trustee or any of the Holders are prevented by applicable law from exercising their respective rights to accelerate the maturity of the Notes, to collect interest on the Notes, or to enforce or exercise any other right or remedy with respect to the Notes, such Guarantor shall pay to the Trustee for the account of the Holders, upon demand therefor, the amount that would otherwise have been due and payable had such rights and remedies been permitted to be exercised by the Trustee or any of the Holders and any other amounts due and owing to the Trustee under this Indenture.

93

(d) If any Holder or the Trustee is required by any court or otherwise to return to the Issuer or any Guarantor, or any custodian, trustee, liquidator or other similar official acting in relation to the Issuer or any Guarantor, any amount paid by any of them to the Trustee or such Holder, the Guarantee of each of the Guarantors, to the extent theretofore discharged, shall be reinstated in full force and effect. This paragraph 10.1(d) shall remain effective notwithstanding any contrary action which may be taken by the Trustee or any Holder in reliance upon such amount required to be returned. This paragraph 10.1(d) shall survive the termination of this Indenture.

(e) Each Guarantor further agrees that, as between each Guarantor, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article VI for the purposes of the Guarantee of such Guarantor, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (y) in the event of any acceleration of such obligations as provided in Article VI, such obligations (whether or not due and payable) shall forthwith become due and payable by each Guarantor for the purpose of the Guarantee of such Guarantor.

(f) Each Guarantor that makes a payment for distribution under its Guarantee is entitled upon payment in full of all guaranteed obligations under this Indenture to seek contribution from each other Guarantor in a pro rata amount of such payment based on the respective net assets of all the Guarantors at the time of such payment in accordance with GAAP.

Section 10.2. Execution and Delivery of Guarantee. To evidence its Guarantee set forth in Section 10.1, each Guarantor agrees that this Indenture or a supplemental indenture in substantially the form attached hereto as Exhibit B shall be executed on behalf of such Guarantor by an Officer of such Guarantor (or, if an officer is not available, by a board member or director) on behalf of such Guarantor by manual or facsimile signature. Each Guarantor hereby agrees that its Guarantee set forth in Section 10.1 hereof shall remain in full force and effect notwithstanding the absence of the endorsement of any notation of such Guarantee on the Notes. In case the Officer, board member or director of such Guarantor whose signature is on this Indenture or supplemental indenture, as applicable, no longer holds office at the time the Trustee authenticates any Note, the Guarantee shall be valid nevertheless.

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

Section 10.3. Severability. In case any provision of any Guarantee shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby.

Section 10.4. Limitation of Guarantors’ Liability. Each Guarantor and by its acceptance hereof each Holder confirms that it is the intention of all such parties that the Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of the Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law or the provisions of its local law relating to fraudulent transfer or conveyance. To effectuate the foregoing intention, the Trustee, the Holders and Guarantors hereby irrevocably agree that the obligations of such Guarantor under its Guarantee (other than a company that is a direct or indirect parent of the Issuer) shall be limited to the maximum amount that will not, after giving effect to all other contingent and fixed liabilities of such Guarantor (including, without limitation, any guarantees under the RCF Credit Agreement) and after giving effect to any collections from, rights to receive contribution from or payments made by or on behalf of any other Guarantor in respect of the obligations of such other Guarantor under its Guarantee, result in the obligations of such Guarantor under its Guarantee constituting a fraudulent conveyance, fraudulent preference or fraudulent transfer or otherwise reviewable under applicable law.

94

Section 10.5. Releases. A Guarantor shall be automatically released of any Obligations under its Guarantee and this Indenture upon:

(a) any sale or other disposition of all or substantially all of the assets of such Guarantor (by merger, consolidation or otherwise) to a Person that is not (either before or after giving effect to such transaction) the Issuer or a Restricted Subsidiary, if the sale or other disposition does not violate Section 4.10 of this Indenture;

(b) any sale, exchange or transfer (by merger, consolidation or otherwise) of the Equity Interests of such Guarantor after which the applicable Guarantor is no longer a Restricted Subsidiary, which sale, exchange or transfer does not violate Section 4.10 of this Indenture;

(c) the proper Designation of such Guarantor by the Issuer as an Unrestricted Subsidiary in accordance with the terms of this Indenture;

(d) in the case of any Restricted Subsidiary that after the Issue Date is required to provide a Guarantee pursuant to Section 4.15, the release or discharge of the guarantee by, or direct obligation of, such Guarantor with respect to the RCF Credit Agreement, Debt Facility or capital markets debt securities that resulted in the creation of such Guarantee;

(e) legal or covenant defeasance or satisfaction and discharge of this Indenture pursuant to Section 8.2, Section 8.3 or Section 8.8; or

(f) dissolution of such Guarantor; provided no Default has occurred that is continuing; or

(g) following the delivery by the Issuer to the Trustee of the Officers’ Certificate on the Termination Date under Section 4.17.

Upon delivery to the Trustee of an Officers’ Certificate and an Opinion of Counsel to the effect that the conditions to release of a Guarantor’s Guarantee set forth above have been satisfied, the Trustee shall execute any documents reasonably requested by the Issuer to evidence such release.

Any Guarantor not released from its obligations under its Guarantee shall remain liable for the full amount of principal of and interest on the Notes and for the other obligations of any Guarantor under this Indenture as provided in this Article X.

Section 10.6. Benefits Acknowledged. Each Guarantor acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated by this Indenture and that its guarantee and waivers pursuant to its Guarantee are knowingly made in contemplation of such benefits.

Section 10.7. Foreign Limitations.

(a) Luxembourg. Notwithstanding anything to the contrary in this Indenture, for the avoidance of doubt:

(i) The Guarantee Obligations of any Luxembourg Guarantor for the Obligations of any Issuer or Guarantor which is not a direct or indirect subsidiary of the relevant Luxembourg Guarantor shall be limited at any time to an aggregate amount not exceeding the higher of:

95

(A) 99% 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”)), increased by the amount of any Intra-Group Liabilities and each determined as at the date of this Agreement, and

(B) 99% of such Luxembourg Guarantor’s capitaux propres (as referred to in article 34 of the 2002 Law as implemented by the Regulation), increased by the amount of any Intra-Group Liabilities and each determined as at the date on which a demand is made under this guaranty.

(C) For the purpose of this Clause 10.7, “Intra-Group Liabilities” shall mean any amounts owed by the Luxembourg Guarantor to any other member of the group to which such Luxembourg Guarantor belongs and that have not been financed (directly or indirectly) by a borrowing under any other Debt Facilities.

(D) The amount of the Luxembourg Guarantor’s capitaux propres under this section shall be (a) determined by the Trustee on the basis of the latest available annual accounts, and (b) 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 the Luxembourg Guarantor.

(E) Where, for the purpose of the above determinations, (i) no duly established annual accounts are available for the relevant reference period (which, for the avoidance of doubt, includes a situation where no final annual accounts have been established in due time in respect of the then most recently ended financial year) or (ii) where the relevant annual accounts do not adequately reflect the status of the Luxembourg Guarantor’s capitaux propres or Intra-Group Liabilities as envisaged above since the close of its last financial year, the determination of the relevant amount will be made by the Trustee (acting reasonably) and in order to prepare such determination, the Trustee shall take into consideration such available elements and facts at such time, including without limitation, the latest annual accounts of such Luxembourg Guarantor and any entities in which it has a direct or indirect equity interest, any recent valuation of the assets of such Luxembourg Guarantor and any entities in which it has a direct or indirect equity interest (if available), the fair value of the assets of such Luxembourg Guarantor and any entities in which it has a direct or indirect equity interest.

The above limitation shall not apply:

(F) in respect of any amounts due under any other Debt Facilities by an Issuer or a Guarantor which is a direct or indirect subsidiary of that Luxembourg Guarantor; or

(G) in respect of any amounts due under any other Debt Facilities by an Issuer or a Guarantor which is not a direct or indirect subsidiary of that Luxembourg Guarantor 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.

Notwithstanding anything to the contrary, no Luxembourg Guarantor guarantees any amounts due under any other Debt Facilities if and to the extent the granting of a guaranty for such amounts would constitute an unlawful financial assistance violating articles 430-19 (where applicable) and 1500-7 of the Luxembourg law dated 10 August 1915 on commercial companies, as amended.

96

(b) Denmark. Notwithstanding anything in the contrary in this Indenture or the Notes:

(i) The Specified Obligations of each Restricted Guarantor shall be limited if and to the extent required to comply with Danish statutory provisions on unlawful financial assistance including, without limitation, (i) section 206(1) of Consolidated Act No. 1451 of 11 September 2022 on public and private limited liability companies as amended and supplemented from time to time (the “Danish Companies Act”) and/or (ii) section 210(1) (as modified by sections 211 and 212 of the Danish Companies Act).

(ii) Without limiting the generality of paragraph (i) above, the Specified Obligations of any Danish Guarantor shall further be limited to the amount equivalent to the higher of the Equity (A) at the date of this Indenture (or, if later, on the date upon which it accedes to this Indenture as a Guarantor) and (B) at the time(s) that a payment is requested from it in respect of any Specified Obligations.

(iii) For purposes of this Section 10.7(b):

“Additional Guaranteed Debt” means indebtedness of the Issuer and any of its Restricted Subsidiaries (other than inter-group indebtedness and indebtedness pursuant to the Credit Documents, this Indenture and the Notes) that is guaranteed by the relevant Danish Guarantor and the obligations under that guarantee is pari passu to such Danish Guarantor’s guarantee obligations in respect of this Indenture.

“Collateral Documents” has the meaning ascribed to such term in the RCF Credit Agreement.

“Credit Documents” has the meaning ascribed to such term in the RCF Credit Agreement.

“Danish Guarantor” means each Guarantor incorporated under Danish law.

“Direct Obligations” means, in respect of any Danish Guarantor (and its Danish and foreign Subsidiaries, as applicable) its (and such Subsidiaries’) liabilities in respect of Indebtedness under a Credit Document in its capacity as a RCF Borrower to the extent that it (and/or such Subsidiaries) is or becomes a primary debtor of such Indebtedness under the relevant Credit Document.

“Equity” means in respect of a Danish Guarantor its equity (in Danish: egenkapital) at the relevant time based on its most recent financial statements prepared in accordance with the accounting principles applied by such Danish Guarantor, which must be in accordance with Danish law, however, adjusted:

(A) in by recognising (if not already so recognised) the unpaid portion, if any, of the subscription price for shares issued by the Danish Guarantor in accordance with the gross method (Da: bruttometoden) pursuant to section 35b of the Danish Financial Statements Act (Da: årsregnskabsloven);

(B) upwards if and to the extent any book value is not equal to market value:

(C) by adding back any loans owed by the Danish Guarantor to its direct shareholder that are generally subordinated (that is, subordinated to all other creditors of the Danish Guarantor) to the extent they have not been included in the calculation of the equity, provided always that any payment made by the Danish Guarantor under any Credit Document, this Indenture, the Notes or in respect of any Additional Guaranteed Debt in respect of such obligations of the Danish Guarantor shall reduce pro tanto the outstanding amount of such subordinated loan by the Danish Guarantor; and

97

(D) by adding back obligations (in the amounts outstanding at the time when a claim for payment is made) of the Danish Guarantor in respect of any intercompany loan owing by the Danish Guarantor to a RCF Borrower as borrower under the RCF Credit Agreement, the Issuer as issuer of the Notes or the borrower or issuer of any Additional Guaranteed Debt, as the case may be, and originally borrowed by that RCF Borrower under the RCF Credit Agreement, by the Issuer as issuer of the Notes or by that borrower or issuer under the Additional Guaranteed Debt, as the case may be, and on-lent by that RCF Borrower, the Issuer as issuer of the Notes or by that borrower or issuer of the Additional Guaranteed Debt, as the case may be, to the Danish Guarantor provided always that any payment made by the Danish Guarantor under the Guaranty and Collateral Agreement or any other Credit Document, this Indenture, the Notes or any similar documentation for any Additional Guaranteed Debt, as the case may be, in respect of the Specified Obligations shall reduce pro tanto the outstanding amount of the intercompany loan owing by the Danish Guarantor.

“Guaranty and Collateral Agreement” has the meaning ascribed to such term in the RCF Credit Agreement.

“Liens” has the meaning ascribed to such term in the RCF Credit Agreement.

“RCF Borrower” has the meaning ascribed to the term “Borrower” in the RCF Credit Agreement.

“Restricted Guarantor” means each Danish Guarantor and its Danish and non-Danish Subsidiaries.

“Secured Obligations” has the meaning ascribed to such term in the RCF Credit Agreement.

“Specified Obligations” means in respect of any relevant Restricted Guarantor, its obligations and liabilities under the guaranty contained in Section 2 of the Guaranty and Collateral Agreement, Section 2.14(d) of the Credit Agreement and Section 10.1 of this Indenture or a similar provision of the documentation for any Additional Guaranteed Debt and in respect of the security and other Liens granted under or pursuant to any Collateral Documents to secure any Secured Obligations and under any other guarantee, indemnity, security, collateral, subordination of rights and/or claims, subordination and/or turnover of rights of recourse, application of proceeds (including mandatory prepayments) provision and any other means or direct or indirect financial assistance under or pursuant to any Credit Documents, this Indenture, the Notes or the documentation for any Additional Guaranteed Debt (including under any Collateral Documents under which it grants security and other Liens to the extent that it secures obligation that are not its or its relevant subsidiaries’ Direct Obligations).

98

(c) Switzerland. Notwithstanding anything to the contrary in this Indenture, for the avoidance of doubt:

(i) If and to the extent that a Swiss Guarantor becomes liable for obligations of its Affiliates other than its Subsidiaries and if complying with such obligations would constitute a repayment of capital (Einlagerückgewähr), a violation of the legally protected reserves (gesetzlich geschützte Reserven) or the payment of a (constructive) dividend ((verdeckte) Gewinnausschüttung) by such Swiss Guarantor or would otherwise be restricted under then applicable Swiss law (the “Swiss Restricted Obligations”), the aggregate liability of the Swiss Guarantor for Swiss Restricted Obligations shall be limited at such time to the amount of unrestricted equity capital available for distribution as dividends to the shareholders or quotaholders, respectively, of the Swiss Guarantor (the “Swiss Available Amount”). The Swiss Available Amount shall be determined on the basis of an audited interim balance sheet of the Swiss Guarantor provided that (A) this limitation shall only apply to the extent it is a requirement under applicable Swiss law at the time the Swiss Guarantor is required to perform under the Swiss Restricted Obligations, and (B) such limitation shall not free the Swiss Guarantor from its obligations in excess of the Swiss Available Amount, but merely postpone the performance date therefor until such times as performance is again permitted.

(ii) In relation to payments made under the Swiss Restricted Obligations, the Swiss Guarantor shall:

(A) procure that such payments can be made without deduction of Swiss Withholding Tax, or with deduction of Swiss Withholding Tax at a reduced rate, by discharging the liability to such tax by notification pursuant to applicable law (including double tax treaties) rather than payment of the tax;

(B) if such notification procedure pursuant to Section 10.7(c)(ii)(A) does not apply:

(I) deduct Swiss Withholding Tax at the rate of 35 per cent (or such other rate as is in force at that time) from any such payment or if the notification procedure pursuant to Section 10.7(c)(ii)(A) applies for a part of the Swiss Withholding Tax only, deduct Swiss Withholding Tax at the reduced rate resulting after the discharge of part of such tax by notification under applicable law;

(II) pay any such deduction to the Swiss Federal Tax Administration;

(III) notify and provide evidence to the Trustee that the Swiss Withholding Tax has been paid to the Swiss Federal Tax Administration; and

(IV) (x) use its best efforts to ensure that any person other than the Trustee, which is entitled to a full or partial refund of the Swiss Withholding Tax deducted from such payment in respect of Swiss Restricted Obligations, will, as soon as possible after such deduction, request a refund of Swiss Withholding Tax under applicable law (including treaties) and pay to the Trustee upon receipt any amounts so refunded; or (y) if the Trustee is entitled to a full or partial refund of the Swiss Withholding Tax deducted from such payment, and if requested by the Trustee, provide the Trustee those documents that are required by law and applicable treaties to be provided by the payer of such tax, for the Trustee, to prepare a claim for refund of Swiss Withholding Tax.

99

(iii) Where a deduction for Swiss Withholding Tax is required to be made in respect of any payment under this Section 10.7(c)(iii) pursuant to Section 10.7(c)(ii), the Trustee shall be entitled to further enforce the Guarantee and other indemnity granted by the Swiss Guarantor under this Indenture and apply proceeds therefrom against the Swiss Restricted Obligations (and the Swiss Guarantor shall withhold Swiss Withholding Tax on the additional amount in accordance with Section 10.7(c)(ii)) so that after making any required deduction of Swiss Withholding Tax, the aggregate amount paid net of Swiss Withholding Tax is equal to the amount which would have resulted if no deduction of Swiss Withholding Tax had been required, subject always to the limitations set out in Section 10.7(c)(ii). This Section 10.7(c)(iii) is without prejudice to the indemnification obligations of the Issuer or any Guarantor other than the Swiss Guarantor in respect of any amounts deducted for the account of Swiss Withholding Tax.

(iv) If and to the extent requested by the Trustee, the Swiss Guarantor shall promptly implement all such measures and/or promptly procure the fulfilment of all prerequisites allowing it to promptly make the requested payment(s) from time to time, including the following:

(A) preparation of an up-to-date audited interim balance sheet of the Swiss Guarantor to the extent required by Swiss corporate law, on the basis of which the Swiss Available Amount will be determined;

(B) confirmation of the auditors of the Swiss Guarantor that the relevant amount represents (the maximum of) the Swiss Available Amount;

(C) approval by a shareholders’ or quotaholders’ meeting of the Swiss Guarantor of the distribution of the relevant requested amount (within the limits of the Swiss Available Amount);

(D) if the enforcement of obligations of the Swiss Guarantor were limited due to the effects referred to in this Section 10.7 and to the extent permitted by applicable Swiss law, write up and/or, to the extent permitted under its Guarantee, realize any of its assets that are shown in its balance sheet with a book value that is lower than the market value of the assets (in case of realization, however, only if such assets are not necessary for the Swiss Guarantor’s business (nicht betriebsnotwendige Aktiven)), and/or convert share capital and statutory reserves into freely available reserves unless prohibited by mandatory law; and

(E) all such measures necessary or useful, and permitted under applicable Swiss law, to allow the Swiss Guarantor to make prompt payments or perform promptly Swiss Restricted Obligations with a minimum of limitations.

(v) No proceeds from the Notes shall be applied in any manner that may be illegal or contravene any applicable law or regulation in any relevant jurisdiction, including those laws or regulations concerning financial assistance by a company for the acquisition of, or subscription for, shares or concerning the protection of shareholders’ capital.

(vi) No proceeds from the Notes shall be used (and neither the Issuer nor any Guarantor shall, and the Issuer shall ensure that none of its Subsidiaries or Affiliates will, use such proceeds) in a manner which constitutes a “use of proceeds in Switzerland” as interpreted by the Swiss Federal Tax Administration for the purposes of Swiss Withholding Tax, unless and to the extent that a written confirmation or countersigned tax ruling application from the Swiss Federal Tax Administration has been obtained and provided in a form satisfactory in advance to the Trustee (acting reasonably), confirming that the intended “use of proceeds in Switzerland” does not result therein that payments in respect of any of the Notes become subject to Swiss Withholding Tax.

Section 11.7. Governing Law; Consent to Jurisdiction. THE LAW OF THE STATE OF NEW YORK SHALL GOVERN AND BE USED TO CONSTRUE THIS INDENTURE, THE NOTES AND THE GUARANTEES (including, without limitation, non-contractual disputes or claims).

Section 11.9. Successors. All agreements of the Issuer and the Guarantors in this Indenture and the Notes and the Guarantees, as applicable, shall bind their respective successors and assigns. All agreements of the Trustee in this Indenture shall bind its respective successors and assigns.

Section 11.11. Execution in Counterparts. This Indenture may be executed in two or more counterparts, which when so executed shall constitute one and the same agreement.

The words “execution,” “signed,” “signature,” “delivery,” and words of like import in or relating to this Agreement or any document to be signed in connection with this Agreement shall be deemed to include electronic signatures, deliveries or the keeping of records in electronic form, each of which shall be of the same legal effect, validity or enforceability as a manually executed signature, physical delivery thereof or the use of a paper-based recordkeeping system, as the case may be, and the parties hereto consent to conduct the transactions contemplated hereunder by electronic means.

Section 11.12. Table of Contents, Headings, Etc. The Table of Contents, Cross-Reference Table and Headings of the Articles and Sections of this Indenture have been inserted for convenience of reference only, are not to be considered a part of this Indenture and shall in no way modify or restrict any of the terms or provisions hereof.

Section 11.13. Acts of Holders.

(a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in person or by agent duly appointed in writing (or, with respect to Global Notes, otherwise in accordance with the rules and procedures of the Depositary); and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee and, where it is hereby expressly required, to the Issuer. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the “Act” of Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and conclusive in favor of the Trustee and the Issuer, if made in the manner provided in this Section 11.13.

(b) The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to such officer the execution thereof. Where such execution is by a signer acting in a capacity other than such signer’s individual capacity, such certificate or affidavit shall also constitute sufficient proof of such signer’s authority. The fact and date of the execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any other manner which the Trustee deems sufficient.

(c) The ownership of Notes shall be proved by the register maintained by the Registrar hereunder.

(d) Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Note shall bind every future Holder of the same Note and the Holder of every Note issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or the Issuer in reliance thereon, whether or not notation of such action is made upon such Note.

(e) If the Issuer shall solicit from the Holders any request, demand, authorization, direction, notice, consent, waiver or other Act, the Issuer may, at its option, by or pursuant to a board resolution of the Issuer’s Board of Directors, fix in advance a record date for the determination of Holders entitled to give such request, demand, authorization, direction, notice, consent, waiver or other Act, but the Issuer shall have no obligation to do so. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act may be given before or after such record date, but only the Holders of record at the close of business on such record date shall be deemed to be Holders for the purposes of determining whether Holders of the requisite proportion of outstanding Notes have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other Act, and for that purpose the outstanding Notes shall be computed as of such record date; provided that no such authorization, agreement or consent by the Holders on such record date shall be deemed effective unless it shall become effective pursuant to the provisions of this Indenture not later than six months after the record date.

104

Section 11.14. Force Majeure. In no event shall the Trustee or Agent be responsible or liable for any failure or delay in the performance of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without limitation, fire, riots, strikes, or work stoppages for any reason, embargoes, governmental actions, accidents, acts of war or terrorism, civil or military disturbances, nuclear or natural catastrophes or acts of God, and interruptions, loss or malfunctions of utilities, communications or computer (software and hardware) services, it being understood that the Trustee shall use reasonable efforts which are consistent with accepted practices in the U.S. banking industry to resume performance as soon as practicable under the circumstances.

Section 11.15. Legal Holidays. If any scheduled payment date with respect to the Notes falls on a day that is not a Business Day, the payment to be made on such payment date will be made on the next succeeding Business Day with the same force and effect as if made on such payment date, and no additional interest will accrue solely as a result of such delayed payment.

Section 11.16. USA PATRIOT Act. The parties hereto acknowledge that in accordance with Section 326 of the USA PATRIOT Act, the Trustee, like all financial institutions and in order to help fight the funding of terrorism and money laundering, is required to obtain, verify, and record information that identifies each person or legal entity that establishes a relationship or opens an account. The Issuer agrees that it will provide the Trustee with information about the Issuer as the Trustee may reasonably request in order for the Trustee to satisfy the requirements of the USA PATRIOT Act.

Section 11.17. Waiver of Jury Trial. EACH OF THE ISSUER, ANY GUARANTOR AND THE TRUSTEE HEREBY, AND EACH HOLDER OF A NOTE BY ITS ACCEPTANCE THEREOF, IRREVOCABLY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE, THE NOTES OR ANY OF THE TRANSACTIONS CONTEMPLATED THEREBY OR HEREBY.

8.000% Senior Notes due 2030

Capitalized terms used herein shall have the meanings assigned to them in the Indenture referred to below unless otherwise indicated.

(1) Interest. Noble Finance II LLC, a Delaware limited liability company, and any successor thereto (the “Issuer”) promises to pay interest on the unpaid principal amount of this 8.000% Senior Note due 2030 (a “Note”) at a fixed rate of 8.000% per annum. The Issuer will pay interest in U.S. dollars semiannually in arrears on April 15 and October 15, commencing October 15, 2023³ (each an “Interest Payment Date”) or if any such day is not a Business Day, on the next succeeding Business Day with the same force and effect as if made on such Interest Payment Date, and no additional interest shall accrue solely as a result of such delayed payment. Interest on the Notes shall accrue from the most recent date to which interest has been paid, or, if no interest has been paid, from and including the date of issuance. The Issuer shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue principal at the rate equal to the then applicable interest rate on the Notes to the extent lawful; it shall pay interest (including post-petition interest in any proceeding under any Bankruptcy Law) on overdue installments of interest (without regard to any applicable grace period), at the same rate to the extent lawful. Interest shall be computed on the basis of a 360-day year comprised of twelve 30-day months.

(2) Method of Payment. The Issuer shall pay interest on the Notes (except defaulted interest) on the applicable Interest Payment Date to the Persons who are registered Holders at the close of business on the April 1 and October 1 preceding the Interest Payment Date (whether or not a Business Day), even if such Notes are cancelled after such record date and on or before such Interest Payment Date, except as provided in Section 2.12 of the Indenture with respect to defaulted interest. If a Holder of at least $5,000,000 aggregate principal amount of the Notes in physical, certificated form has given written wire transfer instructions to the Trustee at least ten Business Days prior to the applicable Interest Payment Date, the Issuer will make all payments of principal, premium, and interest, if any, on such Holder’s Notes by wire transfer of immediately available funds to the account in New York specified in those instructions. Otherwise, payments on the Notes will be made at the office or agency of the Trustee or Paying Agent in the City and State of New York unless the Issuer elects to make interest payments by check mailed to the Holders at their addresses set forth in the register of Holders. Such payment shall be in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts.

Any payments of principal of this Note prior to Stated Maturity shall be binding upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange hereof or in lieu hereof, whether or not noted hereon. The final principal amount due and payable at the maturity of this Note shall be payable only upon presentation and surrender of this Note at an office of the Trustee or the Trustee’s agent appointed for such purposes. Payments in respect of Global Notes will be made by wire transfer of immediately available funds to the Depositary.

(3) Paying Agent and Registrar. Initially, U.S. Bank Trust Company, National Association shall act as Paying Agent and Registrar. The Issuer may change any Paying Agent or Registrar without notice to any Holder, and the Issuer and/or any Restricted Subsidiaries may act as Paying Agent or Registrar.

A-6

(4) Indenture. The Issuer issued the Notes under an Indenture, dated as of April 18, 2023 (the “Indenture”), among the Issuer, the Guarantors thereto and the Trustee. The terms of the Notes include those stated in the Indenture. To the extent the provisions of this Note are inconsistent with the provisions of the Indenture, the Indenture shall govern. The Notes are subject to all such terms, and Holders are referred to the Indenture for a statement of such terms. The Initial Notes issued on the Issue Date were initially issued in an aggregate principal amount of $600,000,000. The Indenture permits the issuance of Additional Notes subject to compliance with certain conditions.

The payment of principal and interest on the Notes and all other amounts under the Indenture is unconditionally guaranteed, jointly and severally, on a senior unsecured basis by the Guarantors.

(5) Redemption and Repurchase. The Notes are subject to optional redemption, and may be the subject of an optional tax redemption, a Net Proceeds Offer and a Change of Control Offer, as further described in the Indenture. The Issuer shall not be required to make mandatory redemption or sinking fund payments with respect to Notes.

(6) Denominations, Transfer, Exchange. The Notes are in registered form without coupons in initial minimum denominations of $2,000 and integral multiples of $1,000 in excess thereof.

The transfer of the Notes may be registered and the Notes may be exchanged as provided in the Indenture. The Registrar, the Trustee and the Issuer may require a Holder, among other things, to furnish appropriate endorsements and transfer documents, and the Issuer may require a Holder to pay any stamp or transfer tax or similar government charge required by law or permitted by the Indenture in accordance with Section 2.6(g)(2) of the Indenture. The Registrar is not required (A) to issue, to register the transfer of or to exchange Notes during a period beginning at the opening of 15 days before the day of any selection of Notes for redemption and ending at the close of business on the day of such selection, (B) to register the transfer of or to exchange any Note so selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part, or (C) to register the transfer of or to exchange a Note between a record date and the next succeeding Interest Payment Date.

(7) Persons Deemed Owners. The registered Holder of a Note will be treated as its owner for all purposes.

(8) Amendment, Supplement and Waiver. The Indenture, the Notes and the Guarantees may be amended or supplemented, and compliance with provisions thereof may be waived, in each case as provided in the Indenture.

(9) Defaults and Remedies. The remedies of Holders in the event of a Default are as set forth in the Indenture.

(10) No Recourse Against Others. No director, officer, employee, incorporator or stockholder, partner or member of the Issuer or any Guarantor, as such, will have any liability for any indebtedness, obligations or liabilities of the Issuer under the Notes or the Indenture or of any Guarantor under its Guarantee or for any claim based on, in respect of, or by reason of, such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The waiver and release are part of the consideration for issuance of the Notes and the Guarantees, to the extent permitted by applicable law.

(11) Authentication. This Note shall not be valid until authenticated by the manual signature of the Trustee or an authenticating agent.

(13) CUSIP Numbers. Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Issuer has caused CUSIP numbers to be printed on the Notes, and the Trustee may use CUSIP numbers in notices of redemption as a convenience to the Holders. No representation is made as to the accuracy of such numbers either as printed on the Notes or as contained in any notice of redemption, and reliance may be placed only on the other identification numbers placed thereon.
