(k) references to “principal amount” of Notes include any increase in the principal amount of outstanding Notes as a result of a PIK Payment.

Section 1.05 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 an agent duly appointed in writing. Except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments or record or both are delivered to the Trustee, the Collateral Custodian, if applicable, and, where it is hereby expressly required, to the Co-Issuers. Proof of execution of any such instrument or of a writing appointing any such agent, or the holding by any Person of a Note, shall be sufficient for any purpose of this Indenture and (subject to Section 7.01) conclusive in favor of the Trustee, the Collateral Custodian and the Co-Issuers, if made in the manner provided in this Section 1.05.

(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 the certificate of any notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof. Where such execution is by or on behalf of any legal entity other than an individual, such certificate or affidavit shall also constitute proof of the authority of the Person executing the same. 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 that the Trustee deems sufficient.

(d) Any request, demand, authorization, direction, notice, consent, waiver or other action by 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 any action taken, suffered or omitted by the Trustee, the Collateral Custodian or the Co-Issuers in reliance thereon, whether or not notation of such action is made upon such Note.

(e) The Co-Issuers may set a record date for purposes of determining the identity of Holders entitled to give any request, demand, authorization, direction, notice, consent, waiver or take any other act, or to vote or consent to any action by vote or consent authorized or permitted to be given or taken by Holders. Unless otherwise specified, if not set by the Co-Issuers prior to the first solicitation of a Holder made by any Person in respect of any such action, or in the case of any such vote, prior to such vote, any such record date shall be the later of 30 days prior to the first solicitation of such consent or the date of the most recent list of Holders furnished to the Trustee prior to such solicitation.

(f) Without limiting the foregoing, a Holder entitled to take any action hereunder with regard to any particular Note may do so with regard to all or any part of the principal amount of such Note or by one or more duly appointed agents, each of which may do so pursuant to such appointment with regard to all or any part of such principal amount. Any notice given or action taken by a Holder or its agents with regard to different parts of such principal amount pursuant to this Section 1.05(f) shall have the same effect as if given or taken by separate Holders of each such different part.

(g) Without limiting the generality of the foregoing, a Holder, including DTC that is the Holder of a Global Note, may make, give or take, by a proxy or proxies duly appointed in writing, any request, demand, authorization, direction, notice, consent, waiver or other action provided in this Indenture to be made, given or taken by Holders, and DTC that is the Holder of a Global Note may provide its proxy or proxies to the beneficial owners of interests in any such Global Note through such depositary’s standing instructions and customary practices.

(h) The Co-Issuers may fix a record date for the purpose of determining the Persons who are beneficial owners of interests in any Global Note held by DTC entitled under the procedures of such depositary to make, give or take, by a proxy or proxies duly appointed in writing, any request, demand,

authorization, direction, notice, consent, waiver or other action provided in this Indenture to be made, given or taken by Holders. If such a record date is fixed, the Holders on such record date or their duly appointed proxy or proxies, and only such Persons, shall be entitled to make, give or take such request, demand, authorization, direction, notice, consent, waiver or other action, whether or not such Holders remain Holders after such record date. No such request, demand, authorization, direction, notice, consent, waiver or other action shall be valid or effective if made, given or taken more than 90 days after such record date.

(i) Notwithstanding anything herein to the contrary, a holder of a beneficial interest in a Global Note will be entitled to exercise rights to vote, give consents and directions which Holders of the related Notes are entitled to give under this Indenture and the other Notes Documents upon delivery of a beneficial ownership certificate in a form acceptable to the Trustee which certifies (i) that such Person is a beneficial owner of an interest in a Global Note, and (ii) the amount of Notes so owned; provided that, nothing shall prevent the Trustee from reasonably requesting additional information and documentation with respect to any such beneficial owner; provided further that the Trustee shall be entitled to conclusively rely on the accuracy and the currency of each beneficial ownership certificate and shall have no liability for relying thereon.

Section 1.06 Limited Condition Transactions.

Notwithstanding anything in this Indenture to the contrary, when (i) calculating availability under any applicable basket or ratio in this Indenture in connection with the incurrence of Indebtedness, the creation of Liens, the making of any Disposition, the making of any acquisitions, the making of an Investment, the making of a Restricted Payment (other than a Restricted Payment pursuant to clause (1) of the definition thereof), the repayment of Indebtedness or for any other purpose, (ii) determining whether any Default or Event of Default has occurred, is continuing or would result from any action or (iii) determining compliance with any representations and warranties and any other condition precedent to any action or transaction, in each case of clauses (i) through (iii) in connection with a Limited Condition Transaction, the date of determination of such basket or ratio, whether any Default or Event of Default has occurred, is continuing or would result therefrom, or the satisfaction of any other condition precedent shall, at the option of the Co-Issuers (the Co-Issuer’s election to exercise such option in connection with any Limited Condition Transaction, a “Transaction Election”), be deemed to be the date of declaration of such Restricted Payment (other than a Restricted Payment made pursuant to clause (1) of the definition thereof) or the date that the definitive agreement for such Restricted Payment (other than a Restricted Payment made pursuant to clause (1) of the definition thereof), Investment, acquisition, Disposition or incurrence, repayment, repurchase or refinancing of Indebtedness, Disqualified Stock or preferred stock is entered into, the date a public announcement of an intention to make an offer in respect of the target of such acquisition or Investment or the date of such notice, which may be conditional, of such repayment, repurchase or refinancing of Indebtedness, Disqualified Stock or preferred stock or such Disposition is given to the holders of such Indebtedness, Disqualified Stock or preferred stock (any such date, the “Transaction Test Date”). If on a pro forma basis after giving effect to such Limited Condition Transaction and the other transactions to be entered into in connection therewith (including any acquisitions, Investments, the incurrence or issuance of Indebtedness, Disqualified Stock or preferred stock and the use of proceeds thereof, the incurrence of Liens, repayments, Restricted Payments (other than a Restricted Payment made pursuant to clause (1) of the definition thereof) and Dispositions) and any related pro forma adjustments, with such baskets and ratios, absence of defaults, satisfaction of conditions precedent and other provisions calculated as if such Limited Condition Transaction or other transactions had occurred on the relevant Transaction Test Date in compliance with the applicable baskets and ratios or other provisions, such provisions shall be deemed to have been complied with. For the avoidance of doubt, (i) if any of such baskets, ratios, absence of defaults, satisfaction of conditions precedent or other provisions are exceeded or breached as a result of fluctuations in such ratio, a change in facts and circumstances or other provisions at or prior to the consummation of the relevant Limited Condition Transaction, such ratios, absence of

defaults, satisfaction of conditions precedent and other provisions will not be deemed to have been exceeded, breached, or otherwise failed to have been satisfied as a result of such fluctuations or changed circumstances solely for purposes of determining whether the Limited Condition Transaction and any related transactions is permitted hereunder and (ii) such baskets and ratios and compliance with such conditions shall not be tested at the time of consummation of such Limited Condition Transaction or related transactions. If the Issuer has made a Transaction Election for any Limited Condition Transaction, then in connection with any subsequent calculation of any ratio or basket availability with respect to any other Limited Condition Transaction or otherwise on or following the relevant Transaction Test Date and prior to the earlier of the date on which such Limited Condition Transaction is consummated or the date that the definitive agreement for such Limited Condition Transaction is terminated or expires without consummation of such Limited Condition Transaction, any such ratio or basket shall be calculated on a pro forma basis assuming such Limited Condition Transaction and other transactions in connection therewith (including any incurrence of Indebtedness and the use of proceeds thereof) have been consummated. For purposes of any calculation of any ratio that includes Fixed Charges or otherwise includes interest expense of any Indebtedness to be incurred, such Fixed Charges or interest expense may be calculated using an assumed interest rate for the Indebtedness to be incurred in connection with such Limited Condition Transaction based on the indicative interest margin contained in any financing commitment documentation with respect to such Indebtedness or, if no such indicative interest margin exists, as reasonably determined by the Issuer in good faith.

Article 2

THE NOTES

Section 2.01 Form and Dating; Terms.

(a) General. The Notes and the Trustee’s certificate of authentication (including any PIK Notes and the related Trustee’s certificate of authentication) shall be substantially in the form of Exhibit A hereto. The Notes may have notations, legends or endorsements required by law, stock exchange rules or usage. Each Note shall be dated the date of its authentication. The Notes shall be in minimum denominations of $1.00 and integral multiples of $1.00 in excess thereof.

(b) Global Notes. Notes issued in global form shall be substantially in the form of Exhibit A hereto (including the Global Note Legend thereon and the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Notes issued in definitive form shall be substantially in the form of Exhibit A hereto (but without the Global Note Legend thereon and without the “Schedule of Exchanges of Interests in the Global Note” attached thereto). Each Global Note shall represent such of the outstanding Notes as shall be specified in the “Schedule of Exchanges of Interests in the Global Note” attached thereto and each shall provide that it shall represent up to the aggregate principal amount of Notes from time to time endorsed thereon and that the aggregate principal amount of outstanding Notes represented thereby may from time to time be reduced or increased, as applicable, to reflect prepayments, exchanges and redemptions. Any endorsement of a Global Note to reflect the amount of any increase or decrease in the aggregate principal amount of outstanding Notes represented thereby resulting from exchange from one Global Note to another shall be made by the Trustee or the Collateral Custodian, at the direction of the Trustee, in accordance with instructions given by the Holder thereof as required by Section 2.06 hereof.

(c) Temporary Global Notes. Notes offered and sold in reliance on Regulation S shall be issued initially in the form of the Regulation S Temporary Global Note, which shall be deposited on behalf of the purchasers of the Notes represented thereby with the Trustee, as custodian for the Notes Depositary, and registered in the name of the Notes Depositary or the nominee of the Notes Depositary for

the accounts of designated agents holding on behalf of Euroclear or Clearstream, duly executed by the Co-Issuers and authenticated by the Trustee as hereinafter provided.

Following the termination of the Restricted Period, beneficial interests in the Regulation S Temporary Global Note shall be exchanged for beneficial interests in the Regulation S Permanent Global Note pursuant to the Applicable Procedures. Simultaneously with the authentication of the Regulation S Permanent Global Note, the Trustee shall cancel the Regulation S Temporary Global Note. The aggregate principal amount of the Regulation S Temporary Global Note and the Regulation S Permanent Global Note may from time to time be increased or decreased by adjustments made on the records of the Trustee and the Notes Depositary or its nominee, as the case may be, in connection with transfers of interest, exchanges, prepayments and redemption as hereinafter provided.

(d) Terms. The aggregate principal amount of Notes that may be authenticated and delivered under this Indenture is unlimited.

The terms and provisions contained in the Notes in Exhibit A attached hereto shall constitute, and are hereby expressly made, a part of this Indenture and the Co-Issuers, the Guarantors and the Trustee, by their execution and delivery of this Indenture, expressly agree to such terms and provisions and to be bound thereby. However, to the extent any provision of any Note conflicts with the express provisions of this Indenture, the provisions of this Indenture shall govern and be controlling.

The Notes shall be subject to repurchase by the Co-Issuers pursuant to a Mandatory Repurchase Offer as provided in Section 3.09 hereof, an ECF Repurchase Offer as provided in Section 4.22 hereof or a Parent Change of Control Offer as provided in Section 4.23 hereof. The Notes shall not be redeemable or prepayable, other than as provided in Article 3.

(e) Euroclear and Clearstream Procedures Applicable. The provisions of the “Operating Procedures of the Euroclear System” and “Terms and Conditions Governing Use of Euroclear” and the “General Terms and Conditions of Clearstream Banking” and “Customer Handbook” of Clearstream shall be applicable to transfers of beneficial interests in the Regulation S Temporary Global Note and the Regulation S Permanent Global Notes that are held by Participants through Euroclear or Clearstream.

(f) PIK Notes. The Co-Issuers shall from time to time issue PIK Notes and/or increase the principal amount of a Global Note as a result of a PIK Payment, if any, in accordance with the applicable provisions of this Indenture. The Initial Notes and PIK Notes will be treated (i) as a single class of securities for all purposes under this Indenture, including waivers, amendments, redemptions and offers to purchase, and (ii) for U.S. federal income tax purposes, as part of the same “issue” pursuant to Treasury Regulations Sections 1.1275-1(f)(4) and 1.1275-2(c)(3).

Section 2.02 Execution and Authentication.

One or more Responsible Officers of each Co-Issuer shall sign the Notes on behalf of the Co-Issuers by manual or facsimile signature.

If a Responsible Officer whose signature is on a Note no longer holds that office at the time a Note is authenticated, the Note shall nevertheless be valid.

A Note shall not be valid until authenticated by the manual signature of the Trustee or an authenticating agent. The signature shall be conclusive evidence that the Note has been authenticated under this Indenture. A Note shall be dated the date of its authentication unless otherwise provided by a board

resolution, a supplemental indenture or an Officer’s Certificate. On the Closing Date, the Trustee shall, upon receipt of an Issuer Order (an “Authentication Order”), authenticate and deliver the Initial Notes. In addition, from time to time, the Trustee shall upon receipt of an Authentication Order in accordance with Section 2.16, authenticate and deliver any PIK Notes in an aggregate principal amount to be determined at the time of issuance and specified therein and/or an increase in the aggregate principal amount of an outstanding Global Note as a result of a PIK Payment in the amount specified therein. Such Authentication Order shall specify the amount of the Notes to be authenticated and/or the amount of the increase in the aggregate principal amount of an outstanding Global Note as a result of a PIK Payment, the date on which the original issue of Notes is to be authenticated and whether the Notes are to be Initial Notes or PIK Notes. Notwithstanding anything to the contrary in this Indenture or Exhibit A, any issuance of PIK Notes, as applicable, after the Closing Date shall be in a principal amount of at least $1.00 and integral multiples of $1.00 in excess thereof.

The Trustee may appoint an authenticating agent acceptable to the Co-Issuers to authenticate Notes. An authenticating agent may authenticate Notes whenever the Trustee may do so. Each reference in this Indenture to authentication by the Trustee includes authentication by such agent. An authenticating agent has the same rights as any Registrar, Paying Agent or agent of services of notices and demands.

Section 2.03 Registrar and Paying Agent.

The Co-Issuers shall maintain an office or agency where Notes may be presented for registration of transfer or for exchange (“Registrar”) and an office or agency where Notes may be presented for payment (“Paying Agent”). The Registrar shall keep a register of the Notes (“Note Register”) and of their transfer and exchange. The Co-Issuers may have one or more co-registrars and one or more additional paying agents. The term “Registrar” includes any co-registrar and the term “Paying Agent” includes any additional paying agent. The Co-Issuers may change any Paying Agent or Registrar without prior notice to any Holder. If the Co-Issuers fail to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. The Co-Issuers hereby appoint the Trustee at its Corporate Trust Office as Registrar and Paying Agent for the Notes unless another Registrar or Paying Agent, as the case may be, is appointed prior to the time the Notes are first issued. The Co-Issuers shall notify the Trustee of the name and address of any Agent not a party to this Indenture.

The Co-Issuers initially appoint DTC to act as Notes Depositary with respect to the Global Notes.

Section 2.04 Paying Agent to Hold Money in Trust.

The Co-Issuers shall, no later than the Allocation Date in connection with each Payment Date, deposit with a Paying Agent cash (which shall be funded in accordance with Section 2.9 of the Collateral Agency and Accounts Agreement) and, if applicable, PIK Notes sufficient to pay such amount, such cash and, if applicable, such PIK Notes to be held in trust for the Holders entitled to the same, and (unless such Paying Agent is the Trustee) the Co-Issuers shall promptly notify the Trustee of their action or failure so to act. The Co-Issuers shall require each Paying Agent other than the Trustee to agree in writing that such Paying Agent shall hold in trust for the benefit of Holders or the Trustee all cash and/or PIK Notes held by such Paying Agent for the payment of principal, premium, if any, and interest on the Notes, and shall notify the Trustee of any default by the Co-Issuers in making any such payment. While any such default continues, the Trustee may require a Paying Agent to pay or deliver, as applicable, all cash and/or PIK Notes held by it to the Trustee. The Co-Issuers at any time may require a Paying Agent to pay all cash and/or PIK Notes held by it to the Trustee. Upon payment over, or delivery, to the Trustee, a Paying Agent shall have no further liability for the cash and/or PIK Notes, as the case may be. If the Parent Guarantor or either Co-

Issuer acts as Paying Agent, it shall segregate and hold in a separate trust fund for the benefit of the Holders all cash held by it as Paying Agent. Upon any bankruptcy or reorganization proceedings relating to the Co-Issuers, the Trustee shall serve as Paying Agent for the Notes. Notwithstanding anything in this Indenture to the contrary, any PIK Payment in the form of an increase in the aggregate principal amount of an outstanding Global Note made in accordance with Sections 2.01(f), 2.16 and 4.01 shall be deemed to comply with this Section 2.04.

Section 2.05 Holder Lists.

The Trustee shall preserve in as current a form as is reasonably practicable the most recent list available to it of the names and addresses of Holders. If the Trustee is not the Registrar, the Co-Issuers shall furnish to the Trustee at least five Business Days before each Payment Date and at such other times as the Trustee may reasonably request in writing, a list in such form and as of such date as the Trustee may reasonably require of the names and addresses of the Holders of Notes.

Section 2.06 Transfer and Exchange.

(a) Transfer and Exchange of Global Notes. Except as otherwise set forth in this Section 2.06, a Global Note may be transferred, in whole and not in part, only to another nominee of the Notes Depositary or to a successor Notes Depositary or a nominee of such successor Notes Depositary. A beneficial interest in a Global Note may not be exchanged for a Definitive Note unless (i) the Notes Depositary (x) notifies the Co-Issuers that it is unwilling or unable to continue as Notes Depositary for such Global Note or (y) has ceased to be a clearing agency registered under the Exchange Act and, in either case, a successor Notes Depositary is not appointed by the Co-Issuers within 120 days or (ii) there shall have occurred and be continuing a Default with respect to the Notes. Upon the occurrence of any of the preceding events in (i) or (ii) above, Definitive Notes delivered in exchange for any Global Note or beneficial interests therein will be registered in the names, and issued in any approved denominations, requested by or on behalf of the Notes Depositary (in accordance with its customary procedures). Global Notes also may be exchanged or replaced, in whole or in part, as provided in Section 2.07 and Section 2.10 hereof. Every Note authenticated and delivered in exchange for, or in lieu of, a Global Note or any portion thereof, pursuant to this Section 2.06 or Section 2.07 or Section 2.10 hereof, shall be authenticated and delivered in the form of, and shall be, a Global Note, except for Definitive Notes issued subsequent to any of the preceding events in (i) or (ii) above and pursuant to Section 2.06(b)(ii)(B) and Section 2.06(c) hereof. A Global Note may not be exchanged for another Note other than as provided in this Section 2.06(a); provided, however, beneficial interests in a Global Note may be transferred and exchanged as provided in Section 2.06(b) or Section 2.06(c) hereof.

(b) Transfer and Exchange of Beneficial Interests in the Global Notes. The transfer and exchange of beneficial interests in the Global Notes shall be effected through the Notes Depositary, in accordance with the provisions of this Indenture and the Applicable Procedures. Beneficial interests in the Restricted Global Notes shall be subject to restrictions on transfer comparable to those set forth herein to the extent required by the Securities Act. Transfers of beneficial interests in the Global Notes also shall require compliance with either subparagraph (i) or (ii) below, as applicable, as well as one or more of the other following subparagraphs, as applicable:

(i) Transfer of Beneficial Interests in the Same Global Note. Beneficial interests in any Restricted Global Note may be transferred to Persons who take delivery thereof in the form of a beneficial interest in the same Restricted Global Note in accordance with the transfer restrictions set forth in the Private Placement Legend; provided, however, that prior to the expiration of the Restricted Period, transfers of beneficial interests in the Regulation S Temporary Global Note may not be made to a U.S. Person or for the account or benefit of a U.S. Person. Beneficial interests in

any Unrestricted Global Note may be transferred to Persons who take delivery thereof in the form of a beneficial interest in an Unrestricted Global Note. No written orders or instructions shall be required to be delivered to the Registrar to effect the transfers described in this Section 2.06(b)(i).

(ii) All Other Transfers and Exchanges of Beneficial Interests in Global Notes. In connection with all transfers and exchanges of beneficial interests that are not subject to Section 2.06(b)(i) hereof, the transferor of such beneficial interest must deliver to the Registrar either (A) (1) a written order from a Participant or an Indirect Participant given to the Notes Depositary in accordance with the Applicable Procedures directing the Notes Depositary to credit or cause to be credited a beneficial interest in another Global Note in an amount equal to the beneficial interest to be transferred or exchanged and (2) instructions given in accordance with the Applicable Procedures containing information regarding the Participant account to be credited with such increase or (B) (1) subsequent to any of the events in clauses (i) or (ii) of Section 2.06(a), a written order from a Participant or an Indirect Participant given to the Notes Depositary in accordance with the Applicable Procedures directing the Notes Depositary to cause to be issued a Definitive Note in an amount equal to the beneficial interest to be transferred or exchanged and (2) instructions given by the Notes Depositary to the Registrar containing information regarding the Person in whose name such Definitive Note shall be registered to effect the transfer or exchange referred to in (1) above; provided, that in no event shall Definitive Notes be issued upon the transfer or exchange of beneficial interests in the Regulation S Temporary Global Note prior to (A) the expiration of the Restricted Period and (B) the receipt by the Registrar of the certificates in the form of Exhibit B hereto. Upon satisfaction of all of the requirements for transfer or exchange of beneficial interests in Global Notes contained in this Indenture and the Notes or otherwise applicable under the Securities Act, the Trustee shall adjust the principal amount of the relevant Global Note(s) pursuant to Section 2.06(h) hereof.

(iii) Transfer of Beneficial Interests to Another Restricted Global Note. A beneficial interest in any Restricted Global Note may be transferred to a Person who takes delivery thereof in the form of a beneficial interest in another Restricted Global Note if the transfer complies with the requirements of Section 2.06(b)(ii) hereof and the Registrar receives the following:

(A) if the transferee will take delivery in the form of a beneficial interest in the 144A Global Note, then the transferor must deliver a certificate in the form of Exhibit B hereto, including the certifications in item (1) thereof;

(B) if the transferee will take delivery in the form of a beneficial interest in the Regulation S Global Note, then the transferor must deliver a certificate in the form of Exhibit B hereto, including the certifications in item (2) thereof; or

(C) if the transferee will take delivery in the form of a beneficial interest in the IAI Global Note, then the transferor must deliver a certificate in the form of Exhibit B hereto, including the certifications, certificates and, if applicable, Opinion of Counsel, in each case as required by item (3)(d) thereof.

(iv) Transfer and Exchange of Beneficial Interests in a Restricted Global Note for Beneficial Interests in an Unrestricted Global Note. A beneficial interest in any Restricted Global Note may be exchanged by any Holder thereof for a beneficial interest in an Unrestricted Global Note or transferred to a Person who takes delivery thereof in the form of a beneficial interest in an Unrestricted Global Note if the exchange or transfer complies with the requirements of Section 2.06(b)(ii) hereof and the Registrar receives the following:

(A) if the Holder of such beneficial interest in a Restricted Global Note proposes to exchange such beneficial interest for a beneficial interest in an Unrestricted Global Note, a certificate from such Holder substantially in the form of Exhibit C hereto, including the certifications in item (1)(a) thereof; or

(B) if the Holder of such beneficial interest in a Restricted Global Note proposes to transfer such beneficial interest to a Person who shall take delivery thereof in the form of a beneficial interest in an Unrestricted Global Note, a certificate from such Holder in the form of Exhibit B hereto, including the certifications in item (4) thereof;

and, in each such case set forth in this Section 2.06(b)(iv), if the Registrar or Co-Issuers so requests or if the Applicable Procedures so require, an Opinion of Counsel in form reasonably acceptable to the Registrar and Co-Issuers to the effect that such exchange or transfer is in compliance with the Securities Act and that the restrictions on transfer contained herein and in the Private Placement Legend are no longer required in order to maintain compliance with the Securities Act.

If any such transfer is effected pursuant to this Section 2.06(b)(iv) at a time when an Unrestricted Global Note has not yet been issued, the Co-Issuers shall issue and, upon receipt of an Authentication Order in accordance with Section 2.02 hereof, the Trustee shall authenticate one or more Unrestricted Global Notes in an aggregate principal amount equal to the aggregate principal amount of beneficial interests transferred pursuant to this Section 2.06(b)(iv).

Beneficial interests in an Unrestricted Global Note cannot be exchanged for, or transferred to Persons who take delivery thereof in the form of, a beneficial interest in a Restricted Global Note.

(i) Beneficial Interests in Restricted Global Notes to Restricted Definitive Notes. If any Holder of a beneficial interest in a Restricted Global Note proposes to exchange such beneficial interest for a Restricted Definitive Note or to transfer such beneficial interest to a Person who takes delivery thereof in the form of a Restricted Definitive Note, then, upon the occurrence of any of the events in clauses (i) or (ii) of Section 2.06(a) hereof and receipt by the Registrar of the following documentation:

The Trustee shall mail such Definitive Notes to the Persons in whose names such Notes are so registered.

Notwithstanding Section 2.06(c)(i)(A) and Section 2.06(c)(i)(C) hereof, a beneficial interest in the Regulation S Temporary Global Note may not be exchanged for a Definitive Note or transferred to a Person who takes delivery thereof in the form of a Definitive Note prior to (A) the expiration of the Restricted Period and (B) the receipt by the Registrar of any certificates required pursuant to Exhibit B hereto, except in the case of a transfer pursuant to an exemption from the registration requirements of the Securities Act other than Rule 903 or Rule 904.

(iii) Beneficial Interests in Restricted Global Notes to Unrestricted Definitive Notes. A Holder of a beneficial interest in a Restricted Global Note may exchange such beneficial interest for an Unrestricted Definitive Note or may transfer such beneficial interest to a Person who takes delivery thereof in the form of an Unrestricted Definitive Note only upon the occurrence of any of the events in subsection (i) or (ii) of Section 2.06(a) hereof and if the Registrar receives the following:

(h) Cancellation and/or Adjustment of Global Notes. At such time as all beneficial interests in a particular Global Note have been exchanged for Definitive Notes or a particular Global Note has been redeemed, repurchased or canceled in whole and not in part, each such Global Note shall be returned to or retained and canceled by the Trustee in accordance with Section 2.11 hereof. At any time prior to such cancellation, if any beneficial interest in a Global Note is exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note or for Definitive Notes, the principal amount of Notes represented by such Global Note shall be reduced accordingly and an endorsement shall be made on such Global Note by the Trustee or by the Notes Depositary at the direction of the Trustee to reflect such reduction; and if the beneficial interest is being exchanged for or transferred to a Person who will take delivery thereof in the form of a beneficial interest in another Global Note, such other Global Note shall be increased accordingly and an endorsement shall be made on such Global Note by the Trustee or by the Notes Depositary at the direction of the Trustee to reflect such increase.

(iv) All Global Notes and Definitive Notes issued upon any registration of transfer or exchange of Global Notes or Definitive Notes shall be the valid obligations of the Co-Issuers, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Global Notes or Definitive Notes surrendered upon such registration of transfer or exchange.

(v) The Co-Issuers shall not be required (A) to issue, to register the transfer of or to exchange any Notes during a period beginning at the opening of business 15 days before the day of any selection of Notes for redemption under Section 3.02 hereof and ending at the close of business on the day of selection, (B) to register the transfer of or to exchange any Note so selected for redemption or tendered (and not withdrawn) for repurchase in connection with a Parent Change of Control Offer, ECF Repurchase Offer, a Mandatory Repurchase Offer or other tender offer, in whole or in part, except the unredeemed or untendered portion of any Note being redeemed or repurchased in part or (C) to register the transfer of or to exchange a Note between a record date and the next succeeding Payment Date.

(vi) Prior to due presentment for the registration of a transfer of any Note, the Trustee, any Agent and the Co-Issuers may deem and treat the Person in whose name any Note is registered as the absolute owner of such Note for the purpose of receiving payment of interest, principal and premium, if any, on such Notes and for all other purposes, and none of the Trustee, any Agent or the Co-Issuers shall be affected by notice to the contrary.

(vii) Upon surrender for registration of transfer of any Note at the office or agency of the Co-Issuers designated pursuant to Section 4.24 hereof, the Co-Issuers shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more replacement Notes of any authorized denomination or denominations of a like aggregate principal amount.

(viii) At the option of the Holder, Notes may be exchanged for other Notes of any authorized denomination or denominations of a like aggregate principal amount upon surrender of the Notes to be exchanged at such office or agency.

(ix) All certifications, certificates and Opinions of Counsel required to be submitted to the Registrar pursuant to this Section 2.06 to effect a registration of transfer or exchange may be submitted by facsimile.

the Notes Depositary) of any notice (including any notice of redemption or purchase) or the payment of any amount or delivery of any Notes (or other security or property) under or with respect to such Notes. The Trustee may rely and shall be fully protected in relying upon information furnished by the Notes Depositary with respect to its members, Participants or Indirect Participants, and any beneficial owners.

(xi) The Trustee shall have no obligation or duty to monitor, determine or inquire as to compliance with any restrictions on transfer imposed under this Indenture or under applicable law with respect to any transfer of any interest in any Note (including any transfers between or among the Notes Depositary’s participants, members, or beneficial owners in any Global Note) other than to require delivery of such certificates and other documentation or evidence as are expressly required by, and to do so if and when expressly required by, the terms of this Indenture, and to examine the same to determine substantial compliance as to form with the express requirements hereof. None of the Trustee, the Collateral Custodian nor any of their agents shall have any responsibility for any actions taken or not taken by the Notes Depositary.

(xii) Each purchaser of the Notes offered hereby will be deemed to have represented and agreed to provide the Co-Issuers and its agents with any correct, complete and accurate information and documentation that may be required for the Co-Issuers to comply with FATCA, the AEOI Regulations and the CRS, and to prevent the imposition of U.S. federal withholding tax under FATCA on payments to or for the benefit of the Co-Issuers, including but not limited to a properly completed and executed “Entity Self-Certification Form” or “Individual Self-Certification Form” (in the forms published by the Cayman Islands Department for International Tax Cooperation, which forms can be obtained at https://www.ditc.ky/category/legislation-resources) on or prior to the date on which it becomes a holder of Notes. In the event such purchaser fails to provide such information or documentation, or to the extent that its ownership of Notes would otherwise cause the Co-Issuers to be subject to any tax under FATCA, (A) the Co-Issuers (and any agent acting on their behalf) are authorized to withhold amounts otherwise distributable to the purchaser as compensation for any tax imposed under FATCA or any fine or penalty imposed under the CRS as a result of such failure or the purchaser’s ownership, and (B) to the extent necessary to avoid an adverse effect on the Co-Issuers as a result of such failure or the purchaser’s ownership, the Co-Issuers will have the right to compel the purchaser to sell its Notes and, if it does not sell its Notes within 10 Business Days after notice from the Co-Issuers or its agents, the Co-Issuers will have the right to sell such Notes at a public or private sale called and conducted in any manner permitted by law, and to remit the net proceeds of such sale (taking into account any taxes incurred by the Co-Issuers in connection with such sale) to the purchaser as payment in full for such Notes. The Co-Issuers may also assign each such Note a separate securities identifier in the Co-Issuers’ sole discretion. It agrees that the Co-Issuers and its agents or representatives may (1) provide any information and documentation concerning its investment in its Notes to the Cayman Islands Tax Information Authority, the IRS and any other relevant tax authority and (2) take such other steps as they deem necessary or helpful to ensure that the Co-Issuers comply with FATCA, the AEOI Regulations and the CRS.

(xiii) Each Co-Issuer is subject to anti-money laundering legislation in the Cayman Islands. Accordingly, if Notes are issued in the form of certificated Notes, each Co-Issuer may, except in relation to certain categories of institutional investors, require a detailed verification of the identity of the purchaser of such certificated Notes and the source of the payment used by such purchaser for purchasing such certificated Notes. The

laws of other major financial centers may impose similar obligations upon the Co-Issuers. Each Holder of a beneficial interest will, by its acquisition of such an interest, be deemed to have represented and agreed to provide the Co-Issuers or their agents with such information and documentation that may be required for the Co-Issuers to achieve compliance with Cayman AML Regulations and shall update or replace such information or documentation, as necessary.

Section 2.07 Replacement Notes.

If any mutilated Note is surrendered to the Trustee, the Co-Issuers shall execute, and the Trustee shall authenticate and deliver in exchange therefor, a new Note of like tenor and principal amount and bearing a number not contemporaneously outstanding.

If there shall be delivered to the Co-Issuers and the Trustee (i) evidence to their satisfaction of the destruction, loss or theft of any Note and (ii) such security or indemnity as may be required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Co-Issuers or the Trustee that such Note has been acquired by a bona fide purchaser, the Co-Issuers shall execute, and upon the Co-Issuers’ request the Trustee shall authenticate and make available for delivery, in lieu of any such destroyed, lost or stolen Note, a new Note of like tenor and principal amount and bearing a number not contemporaneously outstanding.

In case any such mutilated, destroyed, lost or stolen Note has become or is about to become due and payable, the Co-Issuers, in their discretion, may, instead of issuing a new Note, pay such Note.

Upon the issuance of any new Note under this Section, the Co-Issuers may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other expenses (including the fees and expenses of the Trustee) connected therewith.

Every replacement Note is a contractual obligation of the Co-Issuers and shall be entitled to all of the benefits of this Indenture equally and proportionately with all other Notes duly issued hereunder.

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

Section 2.08 Outstanding Notes.

The Notes outstanding at any time are all the Notes authenticated by the Trustee except for those canceled by it, those delivered to it for cancellation, those reductions in the interest in a Global Note effected by the Trustee in accordance with the provisions hereof, and those described in this Section 2.08 as not outstanding. Except as set forth in this Section 2.08 or Section 2.09 hereof, a Note does not cease to be outstanding because the Co-Issuers or an Affiliate of the Co-Issuers holds the Note.

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

If the principal amount of any Note is considered paid under Section 4.01 hereof, it ceases to be outstanding and interest on it ceases to accrue.

If the Paying Agent (other than the Co-Issuers, a Subsidiary or an Affiliate of any thereof) holds, on a redemption date, repurchase date or maturity date, money sufficient to pay Notes payable on

that date, then on and after that date such Notes shall be deemed to be no longer outstanding and shall cease to accrue interest.

For the avoidance of doubt, unless represented by PIK Notes, the aggregate principal amount outstanding under any Note (as reflected in the books and records of the Depositary and the Trustee) shall include any increase in the aggregate principal amount of the applicable Global Notes as a result of a PIK Payment.

Subject to Section 2.09, in determining whether the Holders of the requisite principal amount of outstanding Notes have given any request, demand, authorization, direction, notice, consent or waiver hereunder, the principal amount of Notes that shall be deemed to be outstanding for such purposes shall be the amount of the principal thereof that would be due and payable as of the date of such determination upon a declaration of acceleration of the maturity thereof pursuant to Section 6.02.

Section 2.09 Treasury Notes; Competitors.

(a) In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver or consent, Notes owned by the Co-Issuers, or by any Affiliate of the Co-Issuers, shall be considered as though not outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes that a Responsible Officer of the Trustee actually knows are so owned shall be so disregarded. Notes so owned which have been pledged in good faith shall not be disregarded if the pledgee establishes to the satisfaction of the Trustee the pledgee’s right to deliver any such direction, waiver or consent with respect to the Notes and that the pledgee is not the Co-Issuers or any obligor upon the Notes or any Affiliate of the Co-Issuers or of such other obligor.

(b) In determining whether the Holders of the requisite principal amount of the outstanding Notes have given or taken any request, demand, authorization, direction, notice, consent, waiver or other action pursuant to, or in connection with, this Indenture, the Notes, Guarantees, or Notes Documents, Notes owned by a Competitor will be disregarded and deemed not to be outstanding (it being understood that in determining whether the Trustee is protected in relying upon any such request, demand, authorization, direction, notice, consent, waiver or other action, only Notes in respect of which the Trustee has received prior written notice from the Co-Issuers that such Notes are owned by a Holder that is a Competitor will be so disregarded).

Section 2.10 Temporary Notes.

Until certificates representing Notes are ready for delivery, the Co-Issuers may prepare and the Trustee, upon receipt of an Authentication Order, shall authenticate temporary Notes. Temporary Notes shall be substantially in the form of certificated Notes but may have variations that the Co-Issuers consider appropriate for temporary Notes and as shall be reasonably acceptable to the Trustee. Without unreasonable delay, the Co-Issuers shall prepare and the Trustee shall authenticate definitive Notes in exchange for temporary Notes.

Holders and beneficial Holders, as the case may be, of temporary Notes shall be entitled to all of the benefits accorded to Holders, or beneficial Holders, respectively, of Notes under this Indenture.

Section 2.11 Cancellation.

The Co-Issuers at any time may deliver Notes to the Trustee for cancellation. The Registrar and Paying Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer,

exchange or payment. The Trustee or, at the direction of the Trustee, the Registrar or the Paying Agent and no one else shall cancel all Notes surrendered for registration of transfer, exchange, payment, replacement or cancellation and shall dispose of cancelled Notes (subject to the record retention requirement of the Exchange Act) in accordance with its customary procedures. Certification of the disposal of all cancelled Notes shall be delivered to the Co-Issuers upon its written request. The Co-Issuers may not issue new Notes to replace Notes that it has paid or that have been delivered to the Trustee for cancellation.

Section 2.12 Defaulted Interest.

If the Co-Issuers or the Guarantors default in a payment of interest or principal on the Notes or in the payment of any other amount become due under this Indenture, whether at the Stated Maturity, by acceleration or otherwise, the Co-Issuers shall on written demand of the Trustee pay interest, to the extent permitted by law, on all overdue amounts up to (but not including) the date of actual payment (after as well as before judgment) at a rate equal to the rate then applicable thereto plus 2.00% per annum, pursuant to clause (a) or (b) below, as the Co-Issuers shall elect:

(a) The Co-Issuers may elect to make such payment to the persons who are Holders of the Notes on a subsequent special record date. The Co-Issuers shall fix the payment date for such defaulted interest and the special record date therefor, which shall not be more than 15 days nor less than 10 days prior to such payment date. At least 10 days before the special record date, the Co-Issuers shall mail to the Trustee and to each Holder of the Notes a notice that states the special record date, the payment date and the amount of interest to be paid.

(b) The Co-Issuers may elect to make such payment in any other lawful manner.

Payment of defaulted interest and any interest thereon to the Trustee shall be deemed to satisfy the Co-Issuers’ obligation to pay such defaulted interest and any interest thereon for all purposes of this Indenture.

Section 2.13 CUSIP and ISIN Numbers.

(a) The Co-Issuers in issuing the Notes may use “CUSIP” and/or “ISIN” numbers (if then generally in use), and, if so, the Trustee shall use “CUSIP” and/or “ISIN” numbers in notices as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such numbers either as printed on the Notes or as contained in any notice and that reliance may be placed only on the other elements of identification printed on the Notes, and any such notice shall not be affected by any defect in or omission of such numbers.

(b) The Co-Issuers will as promptly as practicable notify the Trustee in writing of any change in the “CUSIP” and “ISIN” numbers.

Section 2.14 Prohibition on Transfers to Competitors.

The transfer of any Notes to any Competitor is prohibited, and by acceptance of any transferred Note the transferee shall be deemed to represent that it is not a Competitor.

Section 2.15 Co-Issuers.

(a) Joint and Several Liability. All Obligations of the Co-Issuers under this Indenture and the other Transaction Documents shall be joint and several Obligations of the Co-Issuers, each as principal. Anything contained in this Indenture and the other Transaction Documents to the contrary notwithstanding, the Obligations of each Co-Issuer hereunder, solely to the extent that such Co-Issuer did

not receive proceeds of Notes hereunder, shall be limited to a maximum aggregate amount equal to the largest amount that would not render its Obligations hereunder subject to avoidance as a fraudulent transfer or conveyance under §548 of the Bankruptcy Code, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar foreign, federal or state law to the extent applicable to the Obligations of such Co-Issuer (collectively, the “Fraudulent Transfer Laws”), in each case after giving effect to all other liabilities of such Co-Issuer, contingent or otherwise, that are relevant under the Fraudulent Transfer Laws (specifically excluding, however, any liabilities of such Co-Issuer in respect of intercompany Indebtedness to any other Obligor or Affiliates of any other Obligor to the extent that such Indebtedness would be discharged in an amount equal to the amount paid by Obligor hereunder) and after giving effect as assets to the value (as determined under the applicable provisions of the Fraudulent Transfer Laws) of any rights to subrogation or contribution of such Co-Issuer pursuant to (i) applicable law or (ii) any agreement providing for an equitable allocation among such Co-Issuer and other Affiliates of any Obligor of Obligations arising under guarantees by such parties.

(b) Subrogation. Until the Obligations shall have been paid in full in cash, each Co-Issuer shall withhold exercise of any right of subrogation, contribution or any other right to enforce any remedy which it now has or may hereafter have against the other Co-Issuer or any other Obligor of the Obligations. Each Co-Issuer further agrees that, to the extent the waiver of its rights of subrogation, contribution and remedies as set forth herein is found by a court of competent jurisdiction to be void or voidable for any reason, any such rights such Co-Issuer may have against the other Co-Issuer, any collateral or security or any such other Obligor, shall be junior and subordinate to any rights the Notes Secured Parties may have against the other Co-Issuer, any such collateral or security, and any such other Obligor.

(c) Obligations Absolute. Each Co-Issuer hereby waives, for the benefit of the Notes Secured Parties: (1) any right to require any Notes Secured Parties, as a condition of payment or performance by such Co-Issuer, to (i) proceed against any other Co-Issuer or any other Person, (ii) proceed against or exhaust any security held from any other Co-Issuer, any Guarantor or any other Person, (iii) proceed against or have resort to any balance of any deposit account or credit on the books of any Notes Secured Party in favor of any other Co-Issuer or any other Person, or (iv) pursue any other remedy in the power of any Notes Secured Party whatsoever; (2) any defense arising by reason of the incapacity, lack of authority or any disability or other defense of any other Co-Issuer including any defense based on or arising out of the lack of validity or the unenforceability of the Obligations or any agreement or instrument relating thereto or by reason of the cessation of the liability of the other Co-Issuer from any cause other than payment in full of the Obligations; (3) any defense based upon any statute or rule of law which provides that the obligation of a surety must be neither larger in amount nor in other respects more burdensome than that of the principal; (4) any defense based upon any Notes Secured Party’s errors or omissions in the administration of the Obligations, except behavior which amounts to bad faith, gross negligence or willful misconduct; (5) (i) any principles or provisions of law, statutory or otherwise, which are or might be in conflict with the terms hereof and any legal or equitable discharge of such Co-Issuer’s obligations hereunder, (ii) the benefit of any statute of limitations affecting such Co-Issuer’s liability hereunder or the enforcement hereof, (iii) any rights to set-offs, recoupments, recharacterization and counterclaims, and (iv) promptness, diligence and any requirement that any Notes Secured Party protect, secure, perfect or insure any security interest or lien or any property subject thereto; (6) notices, demands, presentments, protests, notices of protest, notices of dishonor and notices of any action or inaction, including acceptance hereof, notices of default hereunder or any agreement or instrument related thereto, notices of any renewal, extension or modification of the Obligations or any agreement related thereto, notices of any extension of credit to such Co-Issuer and any right to consent to any thereof; (7) any defense based upon any rescission, waiver, compromise, acceleration, amendment or modification of any of the terms or provisions of any of the Transaction Documents and (8) any defenses or benefits that may be derived from or afforded by law which limit the liability of or exonerate guarantors or sureties, or which may conflict with the terms hereof.

The obligations of the Co-Issuers hereunder shall not, to the extent permitted by applicable law, be affected by (i) the failure of the Trustee, the Collateral Agent or a Holder to assert any claim or demand or to enforce any right or remedy against any other Obligor under the provisions of this Indenture or any other Transaction Document or otherwise; (ii) any extension or renewal of any provision hereof or thereof; (iii) any rescission, waiver, compromise, acceleration, amendment or modification of any of the terms or provisions of any of the Transaction Documents; (iv) the release, exchange, waiver or foreclosure of any security held by the Collateral Agent or the Trustee for the Obligations or any of them; (v) the failure of the Trustee or a Holder to exercise any right or remedy against any other Obligor; or (vi) the release or substitution of any Collateral or any other Obligor.

To the extent permitted by applicable law, each Co-Issuer hereby waives any defense that it might have based on a failure to remain informed of the financial condition of the other Co-Issuer and of any other Obligor and any circumstances affecting the ability of the Co-Issuers to perform under this Indenture.

Each Co-Issuer further agrees that its obligations hereunder shall continue to be effective or be reinstated, as the case may be, if at any time payment, or any part thereof, of any Obligation is rescinded or must otherwise be restored by the Trustee, any Holder or any other Notes Secured Party upon the bankruptcy or reorganization of the other Co-Issuer or any Guarantor, or otherwise.

Section 2.16 Payment of Interest.

(a) (x) Prior to the consummation of a Public Company Transaction, the Notes shall bear (A) cash interest at a rate of 8.00% per annum and (B) interest payable in-kind at a rate of 4.00% per annum by increasing the principal amount of the outstanding Notes or issuing additional Notes having the same terms and conditions as the other Notes (such notes, “PIK Notes,” such interest payable in-kind, “PIK Interest” and such payment, “PIK Payment”) (rounded up to the nearest $1.00); provided that, at the Co-Issuers’ option, the Co-Issuers may elect, upon notice of such election to the Trustee and the Holders no later than 5 Business Days prior to the Payment Date immediately preceding the applicable Interest Period, to pay interest at a rate of 11.00% per annum payable in cash and (y) after the consummation of a Public Company Transaction, the Notes shall bear interest at a rate of (A) 11.00% per annum payable in cash plus (B) if any Notes are outstanding on the date that is six months after the consummation of a Public Company Transaction, 2.00% per annum payable in cash.

(b) PIK Interest will be payable on the applicable Payment Date (x) with respect to Notes represented by one or more Global Notes registered in the name of, or held by, the Notes Depositary or its nominee on the relevant record date, by increasing the principal amount of the outstanding Global Notes on such Payment Date by an amount equal to the amount of PIK Interest for the applicable Interest Period (rounded up to the nearest $1.00) and upon receipt of an Authentication Order at least five (5) Business Days prior to the applicable Payment Date, the Trustee will cause such Global Notes to be increased and (y) with respect to Definitive Notes, by issuing PIK Notes in certificated form on such Payment Date in an aggregate principal amount equal to the amount of PIK Interest for the applicable Interest Period (rounded up to the nearest $1.00), and the Trustee will, upon receipt of an Authentication Order at least five (5) Business Days prior to the applicable Payment Date, authenticate such PIK Notes in certificated form for delivery to the Holders as of the relevant record date, as evidenced by the Note Register and set forth in the Authentication Order. Following an increase in the principal amount of the outstanding Global Notes as a result of a PIK Payment, the Global Notes will bear interest on such increased principal amount from and after the date of such PIK Payment. Any PIK Notes issued in certificated form will be dated as of the applicable Payment Date and will bear interest from and after such date. All Notes issued pursuant to a PIK Payment will mature on the Stated Maturity and will be governed by, and subject to the terms, provisions and conditions of this Indenture and shall have the same rights and benefits as the Notes

issued on the Closing Date. Any PIK Notes issued in certificated form will be issued with the description “PIK” on the face of such PIK Note, and references to the “principal” or “principal amount” of the PIK Notes shall include any increase in the principal amount of the outstanding Notes as a result of any PIK Payment.

(c) The calculation of PIK Interest will be made by the Co-Issuers or on behalf of the Co-Issuers by such Person as the Co-Issuers shall designate. The Co-Issuers shall notify the Trustee and the Holders in writing not later than ten (10) Business Days prior to the applicable Payment Date of the amount of PIK Interest payable on such Payment Date and the amount of cash interest payable on such Payment Date and shall also specify such PIK Interest and cash interest in the applicable Payment Date Statement. Notwithstanding anything in this Indenture to the contrary, the payment of accrued interest (including interest that would be PIK Interest when paid) in connection with any prepayment or redemption of Notes as described in Paragraph 5 of the Notes (Redemption, Prepayment and Repurchase), Section 3.07, Section 3.08 and Section 3.09 shall be made solely in cash. PIK Interest on the Notes will be paid in denominations of $1.00 and integral multiples of $1.00 in excess thereof. The Trustee shall have no duty to calculate or verify the Co-Issuers’ calculations under the Notes and this Indenture.

Article 3

REDEMPTION

Section 3.01 Notices to Trustee.

If the Co-Issuers elect to redeem Notes pursuant to Section 3.07 hereof, they shall furnish to the Trustee, not less than 10 days before notice of redemption is required to be sent or caused to be sent to Holders pursuant to Section 3.03 hereof but not more than 60 days before a redemption date (except that redemption notices may be delivered more than 60 days prior to a redemption date if the notice is issued in connection with a defeasance of the Notes or a satisfaction and discharge of this Indenture), an Officer’s Certificate setting forth (i) the paragraph or subparagraph of such Note and/or Section of this Indenture pursuant to which the redemption shall occur, (ii) the redemption date, (iii) the principal amount of the Notes to be redeemed and (iv) the redemption price.

Section 3.02 Selection of Notes to Be Redeemed.

If less than all of the Notes are to be redeemed at any time, such Notes shall be selected for redemption by the Trustee (1) if the Notes are listed on an exchange and such listing is known to the Trustee, in compliance with the requirements of such exchange or in the case of Global Notes, in accordance with customary procedures of the Notes Depositary or (2) on a pro rata basis to the extent practicable, or, if the pro rata basis is not practicable for any reason, by lot or by such other method as most nearly approximates a pro rata basis subject to customary procedures of the Notes Depositary. Such Notes to be redeemed shall be selected, unless otherwise provided herein, not less than 10 days nor more than 60 days prior to the redemption date from the outstanding Notes not previously called for redemption.

The Trustee shall promptly notify the Co-Issuers in writing of the Notes selected for redemption and, in the case of any Note selected for partial redemption, the principal amount thereof to be redeemed. Notes and portions of Notes selected shall be in minimum amounts of $1.00 or integral multiples of $1.00 in excess thereof; no Notes of $1.00 or less can be redeemed in part, except that if all of the Notes of a Holder are to be redeemed or purchased, the entire outstanding amount of Notes held by such Holder, even if not a multiple of $1.00, shall be redeemed or purchased. Except as provided in the preceding sentence, provisions of this Indenture that apply to Notes called for redemption also apply to portions of Notes called for redemption.

The Trustee shall not be responsible for any actions taken or not taken by DTC pursuant to its Applicable Procedures.

Section 3.03 Notice of Redemption.

If the Co-Issuers elect to redeem Notes pursuant to Section 3.07 hereof, the Co-Issuers shall deliver notices of redemption electronically or by first-class mail, postage prepaid, at least 10 but not more than 60 days before the purchase or redemption date to each Holder of Notes (with a copy to the Trustee) at such Holder’s registered address or otherwise in accordance with the procedures of DTC, except that redemption notices may be delivered electronically or mailed more than 60 days prior to a redemption date if the notice is issued in connection with Article 8 or Article 11 hereof. Notices of redemption may be conditional.

The notice shall identify the Notes to be redeemed and shall state:

(a) the redemption date;

(b) the redemption price;

(c) if any Note is to be redeemed in part only, the portion of the principal amount of that Note that is 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 of the original Note representing the same indebtedness to the extent not redeemed shall be issued in the name of the Holder of the Notes upon cancellation of the original Note;

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

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

(f) that, unless the Co-Issuers default in making such redemption payment, interest on Notes called for redemption ceases to accrue on and after the redemption date;

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

(h) 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

(i) any condition to such redemption.

At the Co-Issuers’ request, the Trustee shall give the notice of redemption in the Co-Issuers’ names and at their expense; provided that the Co-Issuers shall have delivered written notice to the Trustee, at least 5 Business Days prior to the date on which notice of redemption is to be sent (unless a shorter notice shall be agreed to by the Trustee) in the form of an Officer’s Certificate requesting that the Trustee give such notice and setting forth the information to be stated in such notice as provided in the preceding paragraph.

Any notice of any redemption may be given prior to the redemption thereof, and any such redemption or notice may, at the Co-Issuers’ discretion, be subject to one or more conditions precedent, including the consummation of an incurrence or issuance of debt or equity or a Parent Change of Control

or other corporate transaction. If such redemption is so subject to satisfaction of one or more conditions precedent, such notice shall describe each such condition, and if applicable, shall state that, in the Co-Issuers’ 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 shall be satisfied, or such redemption or purchase may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the redemption date, or by the redemption date as so delayed. In addition, the Co-Issuers may provide in such notice that payment of the redemption price and performance of the Co-Issuers’ obligations with respect to such redemption may be performed by another Person.

Section 3.04 Effect of Notice of Redemption.

Once notice of redemption is sent in accordance with Section 3.03 hereof, Notes called for redemption become irrevocably due and payable on the redemption date at the redemption price, unless such redemption is conditioned on the happening of a future event. The notice, if sent in a manner herein provided, shall be conclusively presumed to have been 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 designated for redemption in whole or in part shall not affect the validity of the proceedings for the redemption of any other Note. Subject to Section 3.05 hereof, on and after the redemption date, interest ceases to accrue on Notes or portions of Notes called for redemption.

Section 3.05 Deposit of Redemption or Purchase Price.

Prior to 4:00 p.m. (Eastern time) on the Business Day prior to the redemption or purchase date, the Co-Issuers shall deposit with the Trustee or with the Paying Agent money sufficient to pay the redemption or purchase price of and accrued and unpaid interest on all Notes to be redeemed or purchased on that date. The Trustee or the Paying Agent shall promptly return to the Co-Issuers any money deposited with the Trustee or the Paying Agent by the Co-Issuers in excess of the amounts necessary to pay the redemption price of, and accrued and unpaid interest on, all Notes to be redeemed or purchased.

If the Co-Issuers comply with the provisions of the preceding paragraph, on and after the redemption or purchase date, interest shall cease to accrue on the Notes or the portions of Notes called for redemption or purchase. If a Note is redeemed or purchased on or after a record date but on or prior to the related Payment Date, then any accrued and unpaid interest to the redemption or purchase date 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 or purchase shall not be so paid upon surrender for redemption or purchase because of the failure of the Co-Issuers to comply with the preceding paragraph, interest shall be paid on the unpaid principal, from the redemption or purchase date until such principal is paid, and to the extent lawful on any interest accrued to the redemption or purchase date not paid on such unpaid principal, in each case at the rate provided in the Notes and in Section 4.01 hereof.

Section 3.06 Notes Redeemed or Purchased in Part.

Upon surrender of a Definitive Note that is redeemed or purchased in part, the Co-Issuers shall issue and the Trustee shall authenticate for the Holder at the expense of the Co-Issuers a new Note equal in principal amount to the unredeemed or unpurchased portion of the Note surrendered representing the same indebtedness to the extent not redeemed or purchased; provided, that each new Note shall be in a principal amount of $1.00 or an integral multiple of $1.00 in excess thereof. It is understood that, notwithstanding anything in this Indenture to the contrary, only an Authentication Order and not an Opinion of Counsel or Officer’s Certificate is required for the Trustee to authenticate such new Note.

Section 3.07 Optional Redemption.

(a) At any time prior to March 12, 2028, the Co-Issuers may on one or more occasions redeem all or a part of the Notes, upon notice as described under Section 3.03 hereof, at a redemption price equal to 100.0% of the principal amount of the Notes (including any PIK Notes) to be redeemed plus the Redemption Premium as of the date of redemption (the “Redemption Date”), plus accrued and unpaid interest, if any, thereon, to, but not including, the applicable Redemption Date; provided that (i) on or prior to June 10, 2025, the Co-Issuers may redeem all (but not less than all) of the principal amount of then-outstanding Notes at a redemption price equal to 108.0% thereof, plus accrued and unpaid interest on the principal amount being redeemed up to, but excluding, the applicable Redemption Date and (ii) upon or after the consummation of a Public Company Transaction, the Co-Issuers may redeem all then-outstanding Notes at a redemption price equal to the lesser of (A) 104.0% thereof and (B) the then-applicable Redemption Premium, in each case, plus accrued and unpaid interest on such Notes up to, but excluding, the applicable Redemption Date; provided that, in the case of this clause (ii), such notice of redemption shall be issued by the Co-Issuers within thirty (30) days of the consummation of such Public Company Transaction and the Redemption Date shall occur within sixty (60) days after the date on which such notice of redemption is issued.

(b) On and after March 12, 2028, the Co-Issuers may on one or more occasions redeem all or a part of the Notes (including any PIK Notes) upon notice as described under Section 3.03 hereof, at a redemption price equal to 100% thereof, plus accrued and unpaid interest, if any, thereon to, but not including the Redemption Date.

Without limiting the generality of the foregoing, it is understood and agreed that if the Notes are accelerated or otherwise become due prior to their stated maturity, in each case, in respect of any Event of Default (including any Bankruptcy Default) (each an “Acceleration Event”), an amount in cash equal to the Redemption Premium with respect to an optional redemption of the Notes shall also be due and payable as though the Notes had been optionally redeemed in full immediately prior to the time of such Acceleration Event and shall constitute part of the Obligations payable to Holders of the Notes in view of the impracticability and extreme difficulty of ascertaining actual damages and by mutual agreement of the parties as to a reasonable calculation of each Holder’s loss as a result thereof. If the Redemption Premium becomes due and payable, it shall be deemed to be principal of the Notes, and interest shall accrue on the full principal amount of the Notes (including the Redemption Premium) from and after the applicable Acceleration Event. Any Redemption Premium payable above shall be presumed to be the liquidated damages sustained by each Holder of the Notes as the result of the acceleration of the Notes and each Co-Issuer and each Guarantor agrees that it is reasonable under the circumstances currently existing. The Redemption Premium shall also be payable in the event the Notes (and/or this Indenture) are satisfied, released or discharged by foreclosure (whether by power of judicial proceeding or otherwise), deed in lieu of foreclosure or by any other similar means. Each Co-Issuer AND EACH GUARANTOR EXPRESSLY WAIVES (TO THE FULLEST EXTENT IT MAY LAWFULLY DO SO) THE PROVISIONS OF ANY PRESENT OR FUTURE STATUTE OR LAW THAT PROHIBITS OR MAY PROHIBIT THE COLLECTION OF THE FOREGOING Redemption PREMIUM IN CONNECTION WITH ANY SUCH ACCELERATION event. Each Co-Issuer and each Guarantor expressly agrees (to the fullest extent it may lawfully do so) that: (A) the Redemption Premium is reasonable and is the product of an arm’s length transaction between sophisticated business people, ably represented by counsel; (B) the Redemption Premium shall be payable notwithstanding the then prevailing market rates at the time acceleration occurs; (C) there has been a course of conduct between the Holders of the Notes and the Co-Issuers and the Guarantors giving specific consideration in this transaction for such agreement to pay the Redemption Premium; and (D) each Co-Issuer and each Guarantor shall be estopped hereafter from claiming differently than as agreed to in this paragraph. Each Co-Issuer and each Guarantor expressly

acknowledges that its agreement to pay the Redemption Premium to the Holders of the Notes as herein described is a material inducement to the Holders to purchase the Notes.

(d) If the optional Redemption Date is on or after a record date and on or before the corresponding Payment Date, the accrued and unpaid interest, if any, to, but not including, the Redemption Date will be paid on the Redemption Date to the Holder in whose name the Note is registered at the close of business on such record date in accordance with the applicable procedures of DTC, and no additional interest will be payable to Holders whose Notes will be subject to redemption by the Co-Issuers.

(e) Any redemption pursuant to this Section 3.07 shall be made pursuant to the provisions of Section 3.01 through Section 3.06 hereof.

Section 3.08 Mandatory Prepayments.

(a) Upon the receipt of Net Proceeds by the Holdco Guarantor, Spirit or any of their Subsidiaries from (i) the issuance or incurrence of any Indebtedness of the Co-Issuers or any Guarantor (other than with respect to any Indebtedness permitted to be incurred pursuant to Section 4.09), (ii) [reserved] or (iii) a Permitted Pre-paid Miles Purchase for which Net Proceeds, together with the aggregate amount of Net Proceeds previously received from Permitted Pre-paid Miles Purchases during the same fiscal year, are in excess of $25.0 million (such excess, “Excess PPM Net Proceeds”) (each of the events set forth in the foregoing clauses (i) and (iii), a “Mandatory Prepayment Event”), the Co-Issuers will cause such Net Proceeds or Excess PPM Net Proceeds, as applicable (the “Applied Mandatory Prepayment Amount”), plus accrued and unpaid interest on the aggregate principal amount of Notes to be prepaid to, but excluding, the Prepayment Date (as defined below) (the “Remitted Amount”), to be remitted to the Trustee to be paid by the Trustee to Holders as of the Prepayment Record Date (as defined below) by a date that is (a) with respect to the Mandatory Prepayment Event set forth in clause (i), five (5) Business Days after the receipt of such Net Proceeds, (b) [reserved], and (c) with respect to the Mandatory Prepayment Event set forth in clause (iii), ten (10) Business Days after the receipt of such Net Proceeds (such remittance date, as the case may be, a “Prepayment Date”).

(b) On such Prepayment Date, the Trustee will apply the Remitted Amount to prepay the maximum principal amount of Notes that may be prepaid with the portion of such Remitted Amount representing the Applied Mandatory Prepayment Amount at a prepayment price equal to the redemption price that would be due if the Notes were being redeemed pursuant to Section 3.07 (including, in the case of any Mandatory Prepayment Event set forth in clause (i) of Section 3.08(a), the Redemption Premium that would be due if the Notes (including any PIK Notes) were being redeemed pursuant to Section 3.07 on the applicable Prepayment Date, plus accrued and unpaid interest on the principal amount being prepaid up to, but excluding, the Prepayment Date. The “Prepayment Record Date” for any Prepayment Date will be the Business Day prior to the Prepayment Date.

(c) Notwithstanding anything to the contrary in Section 3.08(a) or (b), if following a Mandatory Prepayment Event but prior to the related Prepayment Date, the Co-Issuers pay the related Applied Mandatory Prepayment Amount (inclusive of any applicable premium (including the Redemption Premium)) to the Holders on an intervening Payment Date pursuant to the provisions of Section 4.01, no mandatory prepayment pursuant to the provisions of Section 3.08(a) and (b) will be required.

(d) In connection with any mandatory prepayment of the Notes pursuant to this Section 3.08, the Co-Issuers, or the Trustee of behalf of the Co-Issuers pursuant to written instructions from the Co-Issuers to the Trustee, shall issue a written notice to the Holders at least two (2) Business Days prior

to the Prepayment Date, which notice shall include a description of the Mandatory Prepayment Event, the aggregate principal amount of Notes to be prepaid, the prepayment price and the Prepayment Date.

(e) Any prepayment made pursuant to this Section 3.08 shall be made pursuant to the procedures set forth in this Indenture, except to the extent inconsistent with Section 3.08(c). The Co-Issuers shall not be required to make any mandatory prepayment or sinking fund payment with respect to the Notes, except pursuant this Section 3.08 and Section 3.09(b).

Section 3.09 Mandatory Repurchase Offers.

(a) In the event that the Holdco Guarantor, Spirit or any of their Subsidiaries receives Net Proceeds in respect of:

(i) a Recovery Event (“Recovery Event Proceeds”) that causes the aggregate amount of all Recovery Event Proceeds received since the Closing Date to exceed $10.0 million (such excess amounts, “Excess Recovery Event Proceeds”);

(each of the events set forth in clauses (i), (ii), (iii) and (iv), a “Mandatory Repurchase Offer Event”), the Co-Issuers (or the Parent on behalf of the Co-Issuers) shall, except as provided in Section 3.09(b), make an offer (a “Mandatory Repurchase Offer”) to all Holders to purchase the maximum principal amount of Notes on a pro rata basis that may be purchased out of such Excess Recovery Event Proceeds, Excess Contingent Payment Event Proceeds, Excess Notes Priority Collateral Sale Proceeds or Excess Revolving Priority Collateral Sale Proceeds, as applicable (the “Applicable Mandatory Repurchase Offer Proceeds”).

(b) Upon the occurrence of any Mandatory Repurchase Offer Event, the Co-Issuers must (I) promptly deposit the Applicable Mandatory Repurchase Offer Proceeds into the Collateral Proceeds Account and (II) provide notice to the Trustee of such Mandatory Repurchase Offer Event and, as long as no Event of Default shall have occurred and be continuing at the time of such Mandatory Repurchase Offer Event, the Co-Issuers shall have the option to (x) in the case of Excess Revolving Priority

Collateral Sale Proceeds, invest the Excess Revolving Priority Collateral Sale Proceeds within 365 days of receipt thereof in Qualified Replacement Assets, (y) in the case of a Recovery Event, repair, replace or restore the assets which are the subject of such Recovery Event and (z) in the case of Excess Notes Priority Collateral Sale Proceeds, invest such Excess Notes Priority Collateral Sale Proceeds within 365 days of receipt thereof in additional assets that are, or shall become concurrently with such investment, Notes Priority Collateral, and any such Applicable Mandatory Repurchase Offer Proceeds so invested (or, in the case of clause (y), applied to so repair, replace or restore the assets with are subject of such Recovery Event) shall not be required to be applied to make a Mandatory Repurchase Offer pursuant to clause (a) of this Section 3.09 and the Co-Issuers may, upon two (2) Business Days’ prior written notice, direct the Trustee to release to the Co-Issuers from the Collateral Proceeds Account the applicable portion of the Applicable Mandatory Repurchase Offer Proceeds on the date of, and in order to consummate, the transaction described in clause (x), (y) or (z) above, as applicable, such written direction accompanied by an Officer’s Certificate, certifying as to the applicable clause above pursuant to which such amount shall be used and that the release of such amount is in compliance with this Indenture and the other Notes Documents (upon which direction and Officer’s Certificate the Trustee may conclusively rely without independent inquiry or investigation); provided further, that any such Applicable Mandatory Repurchase Offer Proceeds from such Mandatory Repurchase Offer Event that are not invested (or, in the case of clause (y), applied to so repair, replace or restore the assets with are subject of such Recovery Event) within such 365-day period will thereafter be required to be re-deposited into the Collateral Proceeds Account and applied to make a Mandatory Repurchase Offer pursuant to clause (a) of this Section 3.09 (it being understood that the last day of such 365-day period shall constitute the date on which Spirit or the applicable Subsidiary shall have received the Net Proceeds of such Mandatory Repurchase Offer Event).

(d) If the Mandatory Repurchase Date is on or after a record date and on or before the related Payment Date, any accrued and unpaid interest up to but excluding the Mandatory Repurchase Date, shall 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 shall be payable to Holders who tender Notes pursuant to the Mandatory Repurchase Offer.

(e) Subject to Section 3.09(b), notices of a Mandatory Repurchase Offer (“Mandatory Repurchase Offer Notices”) shall be sent by first class mail or sent electronically, no later than (a) with respect to the Mandatory Repurchase Offer Event set forth in clause (i) of Section 3.09(a), five (5) Business Days after the receipt of Net Proceeds therefrom and (b) with respect to the Mandatory Repurchase Offer Event set forth in clause (ii), (iii) or (iv) of Section 3.09(a), ten (10) Business Days after the receipt of Net Proceeds therefrom, in each case, to each Holder at such Holder’s registered address or otherwise in accordance with the applicable procedures of DTC. The Mandatory Repurchase Offer Notice shall contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Mandatory

(vii) that Holders shall be entitled to withdraw their election if the Co-Issuers, the Notes Depositary or the Paying Agent, as the case may be, receives, not later than the expiration of the Mandatory Repurchase Offer Period, a facsimile or other electronic transmission or letter setting forth the name of the Holder, the principal amount of the Notes the Holder delivered for purchase and a statement that such Holder is withdrawing his election to have such Notes purchased;

(viii) that, if the aggregate principal amount of Notes surrendered by the Holders thereof exceeds the amount that can be repurchased with the Applicable Mandatory Repurchase Offer Proceeds, the Trustee shall select the Notes (while the Notes are in global form pursuant to the procedures of the Notes Depositary) to be purchased on a pro rata basis based on the principal amount of the Notes tendered (with such adjustments as may be deemed appropriate by the Co-Issuers so that only Notes in denominations of $1.00, or integral multiples of $1.00 in excess thereof, shall remain outstanding after such purchase) to the extent practicable, or, if the pro rata basis is not practicable for any reason, by lot or by such other method as most nearly approximates a pro rata basis subject to customary procedures of the Notes Depositary; and

(ix) that Holders whose Notes were purchased only in part shall be issued new Notes (or allocated an applicable beneficial interest in the applicable Global Note) equal in principal amount to the unpurchased portion of the Notes surrendered (or transferred by book-entry transfer) representing the same indebtedness to the extent not repurchased.

(f) To the extent that the aggregate principal amount of Notes validly tendered or otherwise surrendered in connection with a Mandatory Repurchase Offer is less than the Applicable Mandatory Repurchase Offer Proceeds, the Co-Issuers may, after purchasing all such Notes validly

tendered and not withdrawn, instruct the Trustee to release the remaining Applicable Mandatory Repurchase Offer Proceeds to the Co-Issuers and may use the remaining Applicable Mandatory Repurchase Offer Proceeds for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of the Notes validly tendered pursuant to any Mandatory Repurchase Offer exceeds the amount that can be repurchased with the Applicable Mandatory Repurchase Offer Proceeds, the Co-Issuers will allocate the Applicable Mandatory Repurchase Offer Proceeds to purchase Notes on a pro rata basis on the basis of the aggregate principal amount of tendered Notes; provided that no Notes will be selected and purchased in an unauthorized denomination. Upon completion of any repurchase of Notes in a Mandatory Repurchase Offer, the amount of Applicable Mandatory Repurchase Offer Proceeds shall be reset at zero and the Co-Issuers may instruct the Trustee to release the remaining Applicable Mandatory Repurchase Offer Proceeds to the Co-Issuers. Together with any instruction of the Co-Issuers to the Trustee pursuant to this Section 3.09(f), the Co-Issuers shall deliver to the Trustee an Officer’s Certificate, certifying that the release of such amount is in compliance with this Indenture and the other Notes Documents (upon which direction and Officer’s Certificate the Trustee may conclusively rely without independent inquiry or investigation).

(g) On or before the Mandatory Repurchase Date, the Co-Issuers shall, to the extent lawful, (1) accept for payment, on a pro rata basis to the extent necessary, the Notes or portions thereof validly tendered pursuant to the Mandatory Repurchase Offer, or if the aggregate Mandatory Offer Repurchase Price for all Notes so tendered in such Mandatory Repurchase Offer does not exceed the total amount of Applicable Mandatory Repurchase Offer Proceeds, all Notes tendered and (2) deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officer’s Certificate stating the aggregate principal amount of Notes or portions thereof so tendered.

(h) The Co-Issuers, the Notes Depositary, the Paying Agent or the Trustee, as the case may be, shall promptly mail or deliver to each tendering Holder from amounts held in the Collateral Proceeds Account an amount equal to the repurchase price of the Notes properly tendered by such Holder and accepted by the Co-Issuers for repurchase, and the Co-Issuers shall promptly issue a new Note, and the Trustee, upon receipt of an Authentication Order, shall authenticate and mail or deliver (or cause to be transferred by book-entry) such new Note to such Holder (it being understood that, notwithstanding anything in this Indenture to the contrary, no Opinion of Counsel or Officer’s Certificate is required for the Trustee to authenticate and mail or deliver such new Note) in a principal amount equal to any unpurchased portion of the Note surrendered representing the same indebtedness to the extent not repurchased; provided, that each such new Note shall be in a minimum denomination of $1.00 or an integral multiple of $1.00 in excess thereof. Any Note not so accepted shall be promptly mailed or delivered by the Co-Issuers to the Holder thereof. The Co-Issuers shall publicly announce the results of the Mandatory Repurchase Offer on or as soon as practicable after the Mandatory Repurchase Date.

(i) To the extent that the provisions of any securities laws or regulations, including Rule 14e-1 under the Exchange Act, conflict with the provisions of this Indenture, the Co-Issuers shall not be deemed to have breached their obligations described in this Indenture by virtue of compliance therewith.

Article 4

COVENANTS

Section 4.01 Payment of Notes.

On each Payment Date prior to (i) the occurrence and continuance of a Bankruptcy Default or (ii) the occurrence and continuance of any other Event of Default with respect to which the Collateral Agent (at the direction of the Required Debtholders) or the Trustee (at the direction of the Permitted Noteholders) has provided the Co-Issuers with at least two (2) Business Days’ prior written notice that this

Section 4.01 shall no longer apply, all Available Funds in the Notes Payment Account on such Payment Date (based upon instructions in the Payment Date Statement furnished to it on the related Determination Date by the Co-Issuers) shall be distributed by the Trustee in the following order of priority (the “Payment Waterfall”):

(a) first, ratably to the Trustee and the Collateral Custodian, Fees, costs, expenses, reimbursements and indemnification amounts due and payable to such Persons pursuant to the terms of this Indenture and the other Notes Documents in an amount not to exceed $200,000 in the aggregate per annum;

(b) second, to the Trustee, on behalf of the Holders, an amount equal to the Interest Distribution Amount with respect to such Payment Date minus the amount of interest paid by the Co-Issuers in connection with any redemptions, prepayments or repurchases of any Notes pursuant to this Indenture after the immediately preceding Payment Date and prior to such Payment Date;

(c) third, on the Termination Date only, to the Trustee, on behalf of the Holders, in an amount equal to the outstanding principal amount of the Notes;

(d) fourth, to the Notes Reserve Account, to the extent the amount on deposit in the Notes Reserve Account is less than the Notes Reserve Account Required Balance for the following Payment Date;

(e) fifth, to the extent not already paid, to the Trustee on behalf of the Holders, the Remitted Amount for any mandatory prepayments required pursuant to Section 3.08;

(f) sixth, any premium without any duplication for any premium paid pursuant to Section 4.01(e) due and unpaid as of such Payment Date;

(g) seventh, to pay (x) ratably to the Trustee and the Collateral Custodian, and then (y) to any other Person (other than Spirit and any of its Subsidiaries), any additional Obligations due and payable to such Person on such Payment Date to the extent not paid pursuant to clause (a) through clause (f) of this Section 4.01;

(h) eighth, if a Cash Trap Period is in effect as of the last day of the related Quarterly Reporting Period and a Cash Trap Cure has not occurred on or prior to such Payment Date, then to the ECF Account, an amount equal to the Required Excess Cash Flow for such Payment Date;

(i) ninth, [reserved]; and

(j) tenth, (i) if an Event of Default has occurred and is continuing, all remaining amounts shall be remitted to, and remain on deposit in, the applicable Collection Account (as specified in the Payment Date Statement) (and held under the sole control of the Collateral Agent) or (ii) if no Event of Default has occurred and is continuing, all remaining amounts shall be released to or at the direction of the Co-Issuers, which may be distributed directly or indirectly to Spirit without any restriction.

For the avoidance of doubt, to the extent Available Funds with respect to any Payment Date are insufficient to pay amounts due under this Indenture to the Agents, Holders or any other Person on such Payment Date, the Co-Issuers, and to the extent provided in Article 10 hereof, the Guarantors, are fully obligated to timely pay such amounts to the Agents, Holders or other Persons.

PIK Interest will be considered paid on the date due if prior to such date the Trustee has received (i) an Authentication Order to increase the aggregate principal amount of an outstanding Global Note as a

result of a PIK Payment in the amount set forth in such Authentication Order or (ii) PIK Notes duly executed by the Co-Issuers together with an Authentication Order pursuant to Section 2.02 requesting the authentication of such PIK Notes by the Trustee as of such Payment Date.

Section 4.02 Collections.

(a) Spirit shall instruct and use commercially reasonable efforts to cause sufficient counterparties to Free Spirit Agreements to direct all payments of Free Spirit Program Revenues into the Loyalty Collection Account such that in any Quarterly Reporting Period, at least 90% of the aggregate amount of Free Spirit Program Revenues are deposited directly into the Loyalty Collection Account. To the extent any Co-Issuer or Guarantor or any of their respective controlled Affiliates receives any such payments to an account other than the Loyalty Collection Account, such Person shall cause such amounts to be deposited into the Loyalty Collection Account within two (2) Business Days after receipt and identification thereof.

(b) Spirit shall cause all reasonably identifiable revenues of the Saver$ Club, but in any event no less than 90% of all Saver$ Club Transaction Revenues, received by Spirit to be deposited into the Loyalty Collection Account within two business days after receipt and identification thereof.

(c) Other than as required to provide for any successor account that becomes the Loyalty Collection Account, no Co-Issuer or Guarantor shall revoke, or permit to be revoked, any Direction of Payment.

Section 4.03 Collection Account; Debt Service Coverage Ratio Cure.

(a) Spirit shall determine the Required Deposit Amount and notify the Trustee and the Collateral Agent in writing of such Required Deposit Amount for each Quarterly Reporting Period no later than the fifth Business Day of such Quarterly Reporting Period; provided that at any time that Spirit determines that the Required Deposit Amount for a Quarterly Reporting Period is greater (including as a result of the occurrence of a Cash Trap Event) or less, than the Required Deposit Amount for such Quarterly Reporting Period as previously calculated, then Spirit shall promptly (i) notify the Trustee and the Collateral Agent in writing and (ii) such revised Required Deposit Amount shall thereafter be applicable for such Quarterly Reporting Period, unless subsequently revised; provided that the effect of such increase shall be to stop further withdrawals from any Collection Account but shall not require the deposit of additional funds. The Co-Issuers shall only be permitted to withdraw or release funds from the Collection Accounts in accordance with the terms of the Collateral Agency and Accounts Agreement.

(b) Subject to the terms of the Collateral Documents, the Guarantors may or may cause any of their Affiliates (with written notice to the Collateral Agent) to deposit amounts into a Collection Account from time to time prior to a Payment Date, but such amounts (other than Cure Amounts or to the extent constituting Transaction Revenues) shall not constitute “Collections” for purposes of the Debt Service Coverage Ratio.

(d) [Reserved].

(e) To the extent that Collections received in the Collection Accounts with respect to any Quarterly Reporting Period are insufficient to satisfy the Debt Service Coverage Ratio Test for such Quarterly Reporting Period, the Co-Issuers may deposit, or cause to be deposited into the Collection Accounts, funds in an amount necessary to satisfy the Debt Service Coverage Ratio Test for such Quarterly

Reporting Period (such deposited amounts, the “Cure Amounts”); provided that such deposit and deemed cures shall not occur more than five (5) times in the aggregate since the Closing Date and no more than two (2) times in any four (4) fiscal periods. To the extent that Cure Amounts are received in a Collection Account on or prior to the Payment Date with respect to the Quarterly Reporting Period in which such funds are necessary to satisfy the Debt Service Coverage Ratio Test, Cure Amounts will be treated as Collections for such Quarterly Reporting Period for purposes of the Debt Service Coverage Ratio. Any Cure Amounts received in a Collection Account on or prior to the Determination Date for such Quarterly Reporting Period shall be allocated to the Notes Payment Account on the Allocation Date with respect to such Quarterly Reporting Period pursuant to the terms of the Collateral Agency and Accounts Agreement. Any Cure Amounts received in a Collection Account following the Determination Date with respect to such Quarterly Reporting Period shall not be allocated to the Notes Payment Account on the Allocation Date with respect to such Quarterly Reporting Period and shall be allocated to the Quarterly Reporting Period in which such funds were deposited.

Section 4.04 Notes Payment Account.

(a) The Co-Issuers shall establish and maintain or cause to be maintained at the Collateral Custodian, a segregated non-interest bearing trust account in the name of one or both Co-Issuers (as specified in the applicable Account Control Agreement), for the purpose of holding amounts transferred thereto from the Collection Accounts on each Allocation Date pursuant to the terms of the Collateral Agency and Accounts Agreement (such account, the “Notes Payment Account”). The Notes Payment Account shall be subject at all times to an Account Control Agreement. Amounts on deposit in the Notes Payment Account shall remain uninvested.

(b) On each Allocation Date, the Notes Payment Account shall be funded with amounts allocated from the Collection Accounts as contemplated under Section 4.03 in accordance with the terms of the Collateral Agency and Accounts Agreement.

(c) As security for the prompt payment or performance in full when due, whether at stated maturity, by acceleration or otherwise, of all Obligations, the Co-Issuers hereby grant to the Trustee for the benefit of the Notes Secured Parties a security interest in and lien upon, all of the Co-Issuers’ right, title and interest in and to (i) the Notes Payment Account, (ii) all funds held in the Notes Payment Account, and all certificates and instruments, if any, from time to time representing or evidencing any account or such funds, (iii) all Investments from time to time of amounts in the Notes Payment Account and all certificates and instruments, if any, from time to time representing or evidencing such Investments, (iv) all notes, certificates of deposit and other instruments from time to time delivered to or otherwise possessed by the Trustee or any Notes Secured Party or any assignee or agent on behalf of the Trustee or any Notes Secured Party in substitution for or in addition to any of the then existing Collateral in the Notes Payment Account, and (v) all interest, dividends, cash, instruments and other property from time to time received, receivable or otherwise distributed in respect of or in exchange for any and all of the then existing Collateral in the Notes Payment Account.

(d) Each Co-Issuer and Guarantor hereby acknowledges and agrees that at all times, the Trustee shall be the only Person that has a right to withdraw from the Notes Payment Account and the funds on deposit in the Notes Payment Account shall at all times continue to be Collateral security for all of the Obligations.

(e) If, at any time, the Notes Payment Account shall no longer be an Eligible Account, the Co-Issuers shall provide prompt written notice to the Trustee and, within sixty (60) days, move the Notes Payment Account to a new depositary institution pursuant to Section 7.11.

Section 4.05 Notes Reserve Account.

(a) The Co-Issuers shall establish and maintain or cause to be maintained at the Collateral Custodian, a segregated non-interest bearing trust account in the name of one or both Co-Issuers (as specified in the applicable Account Control Agreement) (such account, the “Notes Reserve Account”), for the purpose of holding a minimum balance of not less than the Notes Reserve Account Required Balance at all times, and the Co-Issuers will maintain a minimum balance of not less than the Notes Reserve Account Required Balance in the Notes Reserve Account at all times, except for periods between any Determination Date and Payment Date to the extent resulting from the application of funds in the Notes Reserve Account into the Notes Payment Account. The Notes Reserve Account shall be subject at all times to an Account Control Agreement.

(b) So long as the Collateral Custodian has not been notified by the Trustee or any Co-Issuer that an Event of Default exists, then the Collateral Custodian shall, at the written direction of either Co-Issuer from time to time cause the funds held in the Notes Reserve Account, from time to time, to be invested in one or more Cash Equivalents selected by such Co-Issuer (which Cash Equivalents shall at all times be subject to the Lien created hereunder); provided that in no event shall the Collateral Custodian: (i) have any responsibility whatsoever as to the validity or quality of any Cash Equivalent, (ii) be liable for the selection of Cash Equivalents or for investment losses incurred thereon or in respect of losses incurred as a result of the liquidation of any Cash Equivalent before its stated maturity pursuant to this Section 4.05 or the failure of a Co-Issuer to provide timely written investment direction or (iii) have any obligation to invest or reinvest any such amounts in the absence of such investment direction. Notwithstanding anything else in this Indenture to the contrary, in no event shall any Co-Issuer direct any investment in any such Cash Equivalent that will mature later than the Business Day before the next occurring Payment Date. It is agreed and understood that the entity serving as the Trustee or the Collateral Custodian may earn fees associated with the investments outlined above in accordance with the terms of such investments. In no event shall the Trustee or the Collateral Custodian be deemed an investment manager or adviser in respect of any selection of investments hereunder. It is understood and agreed that the Trustee, the Collateral Custodian or their respective affiliates are permitted to receive additional compensation that could be deemed to be in the Trustee’s or the Collateral Custodian’s economic self-interest for (1) serving as investment adviser, administrator, shareholder servicing agent, custodian or sub custodian with respect to certain of the investments, (2) using affiliates to effect transactions in certain investments and (3) effecting transactions in investments. All income from such Cash Equivalents shall be retained in the Notes Reserve Account, subject to release as permitted by this Indenture. All investments in such Cash Equivalents shall be at the risk of the Co-Issuers. All income from Investments in the Notes Reserve Account shall be taxable to the Co-Issuers (or their regarded parent entity), and the Collateral Custodian shall prepare and timely distribute to the Co-Issuers, as required, Form 1099 or other appropriate U.S. federal and state income tax forms with respect to such income.

(c) As security for the prompt payment or performance in full when due, whether at stated maturity, by acceleration or otherwise, of all Obligations, each Co-Issuer hereby grants to the Trustee for the benefit of the Notes Secured Parties a security interest in and lien upon, all of the Co-Issuers’ right, title and interest in and to (i) the Notes Reserve Account, (ii) all funds held in the Notes Reserve Account, and all certificates and instruments, if any, from time to time representing or evidencing any account or such funds, (iii) all Investments from time to time of amounts in the Notes Reserve Account and all certificates and instruments, if any, from time to time representing or evidencing such Investments, (iv) all notes, certificates of deposit and other instruments from time to time delivered to or otherwise possessed by the Trustee or any Notes Secured Party or any assignee or agent on behalf of the Trustee or any Notes Secured Party in substitution for or in addition to any of the then existing Collateral in the Notes Reserve Account, and (v) all interest, dividends, cash, instruments and other property from time to time received,

receivable or otherwise distributed in respect of or in exchange for any and all of the then existing Collateral in the Notes Reserve Account.

(d) The Co-Issuers hereby acknowledge and agree that the Trustee shall be the only Person that has a right to withdraw from the Notes Reserve Account. The funds on deposit in the Notes Reserve Account shall at all times continue to be Collateral security for the benefit of the Notes Secured Parties.

(e) If, at any time, the Notes Reserve Account shall no longer be an Eligible Account, the Co-Issuers shall provide prompt written notice to the Trustee and, within sixty (60) days, move the Notes Reserve Account to a new depositary institution pursuant to Section 7.11.

(f) If, on any Determination Date, the amount on deposit in the Notes Reserve Account would exceed the then applicable Notes Reserve Account Required Balance for the related Payment Date, the Co-Issuers shall be entitled to request the Trustee by notice in writing (which may be the Payment Date Statement) to transfer such excess amounts in the Notes Reserve Account to a Collection Account. In such circumstances, the Trustee shall promptly direct the Collateral Custodian to wire such excess amounts from the Notes Reserve Account to the Collection Account specified by the Co-Issuers.

(g) If, on any Determination Date, the Available Funds for the related Payment Date will not be sufficient to pay the amounts due in accordance with Section 4.01(a) through Section 4.01(c) on the related Payment Date, the Co-Issuers shall request by notice in writing (which may be the Payment Date Statement) to the Trustee that the Trustee, on or prior to the related Payment Date, transfer amounts in the Notes Reserve Account to the Notes Payment Account to the extent necessary so that the Available Funds on the related Payment Date will be sufficient to pay such amounts. In such circumstances, the Trustee shall promptly direct the Collateral Custodian to wire such amounts from the Notes Reserve Account to the Notes Payment Account.

Section 4.06 Operation of the Free Spirit Program.

(a) Each Co-Issuer and Guarantor (as applicable) agrees to honor Miles according to the policies and procedure of the Free Spirit Program, subject to cure, except to the extent that would not be reasonably expected to cause a Material Adverse Effect, and shall take any action permitted under the Free Spirit Agreements and applicable law that it, in its reasonable business judgment, determines is advisable, in order to diligently and promptly (i) enforce its rights and any remedies available to it under the Free Spirit Agreements, (ii) perform its obligations under the Free Spirit Agreements and (iii) cause the applicable counterparties to perform their obligations under the related Free Spirit Agreements, including such counterparties’ obligations to make payments to and indemnify the applicable Co-Issuer or Guarantor in accordance with the terms thereof, in each case except as would not reasonably be expected to result in a Material Adverse Effect.

(b) Neither any Co-Issuer nor Spirit shall substantially reduce the Free Spirit Program business or modify the terms of the Free Spirit Program in any manner that would reasonably be expected to result in a Material Adverse Effect.

(c) Spirit shall not and shall not permit any of its Subsidiaries to change the policies and procedures of the Free Spirit Program except to the extent that such change would not be reasonably expected to cause a Material Adverse Effect.

(d) Each of the Co-Issuers and the Guarantors shall not, and shall not permit any of their respective Subsidiaries to, establish, create or operate any Loyalty Program, other than a Permitted

Acquisition Loyalty Program, unless substantially all such Loyalty Program cash proceeds (which excludes, for the avoidance of doubt, airline revenues such as ticket sales and non-loyalty ancillary revenue), accounts in which such cash receipts are deposited, Intellectual Property and member data (but solely to the extent that such Intellectual Property and member data would be included in the definition of Loyalty Program Intellectual Property, substituting references to the Free Spirit Program and the Saver$ Club, as applicable, with references to such other Loyalty Program) are pledged as Collateral on a first lien basis, subject to Third-Party Rights and other Permitted Liens; provided that, for the avoidance of doubt, nothing will prohibit the Co-Issuers or the Guarantors or any of their respective Subsidiaries from offering and providing discounts or other incentives (other than any Currency) for travel or carriage on Spirit.

With respect to any Permitted Acquisition Loyalty Program, the Co-Issuers and the Guarantors will be permitted to undertake the following actions at any time after such actions are permitted under the Material Free Spirit Agreements, such Permitted Acquisition Loyalty Program’s co-branding, partnering or similar agreements and debt obligations and applicable law: (i) terminate the Permitted Acquisition Loyalty Program; (ii) merge and consolidate the Permitted Acquisition Loyalty Program into the Free Spirit Program; or (iii) cause the Permitted Acquisition Loyalty Program’s cash receipts (which excludes airline revenues such as ticket sales and non-loyalty ancillary revenue), accounts in which such cash receipts are deposited, Intellectual Property and member data to be pledged as Collateral.

Until it is merged into or consolidated with the Free Spirit Program, any Permitted Acquisition Loyalty Program shall not constitute a Free Spirit Program and its co-branding, partnering or similar agreements shall not constitute Free Spirit Agreements.

(e) On each Determination Date, the Loyalty Issuer shall deliver or cause to be delivered to the Trustee an updated Schedule 4.06(e), attached as Annex I to the corresponding Payment Date Statement, to the extent necessary to cause the Material Free Spirit Agreements listed on such updated schedule, in the aggregate, to represent at least 85% of the Free Spirit Program Revenues in the prior twelve (12) months.

(f) If, as of any Determination Date, the aggregate amount of Retained Agreement Revenues for the preceding four Quarterly Reporting Periods (or, in the case of the first three Quarterly Reporting Periods, since the Closing Date) are greater than or equal to 5.0% of the Free Spirit Program Revenues for such period, (i) Spirit shall promptly assign its rights to receive payment under one or more Retained Agreements to the Loyalty Issuer such that the aggregate amount of revenues produced by the Retained Agreements not so assigned is less than 5.0% of the Free Spirit Program Revenues in such period (on a pro forma basis). Upon the effectiveness of such assignment, such Retained Agreement(s) shall become Free Spirit Agreement(s).

(g) Each Co-Issuer and Guarantor shall maintain in effect commercially reasonable privacy and data security policies. Without limiting the generality of the foregoing, except as would not reasonably be expected to result in a Material Adverse Effect, each applicable Co-Issuer and Guarantor shall comply in all material respects, and shall cause each of its Subsidiaries and each of its Third Party Processors to be in compliance in all material respects with (i) all internal privacy policies and privacy policies contained on any websites maintained by or on behalf of such Co-Issuer or Guarantor or such Subsidiary and such policies are accurate, not misleading and consistent with the actual practices of such Co-Issuer or Guarantor, (ii) all Data Protection Laws with respect to Personal Data of the United States, the State of California, the United Kingdom, the Cayman Islands, and the European Union and (iii) its contractual commitments and obligations regarding Personal Data.

Section 4.07

Maintenance of Rating.

The Co-Issuers and the Guarantors shall use commercially reasonable efforts to (x) cause the Notes to be rated by both of the Rating Agencies within 30 days of the Closing Date and (y) cause the Notes to be continuously rated by both of the Ratings Agencies but, in each case, shall not be required to obtain any specific rating. The Co-Issuers and the Guarantors shall make commercially reasonable efforts to provide the Rating Agencies (at Spirit’s sole expense) such reports, records and documents as each shall reasonably request to monitor or affirm such ratings, except to the extent the disclosure of any such document or any such discussion would result in the violation of any Co-Issuer’s or Guarantor’s contractual (including all confidentiality obligations set forth in the Free Spirit Agreements) or legal obligations; provided that the Co-Issuers’ or Guarantors’ failure to obtain such a rating after using commercially reasonable efforts shall not constitute an Event of Default.

Section 4.08 Restricted Payments.

(a) Spirit shall not, and shall not permit any of its Subsidiaries to, directly or indirectly:

(1) declare or pay any dividend or make any other payment or distribution on account of Spirit’s or any of its Subsidiaries’ Equity Interests (including any payment in connection with any merger or consolidation involving Spirit or any of its Subsidiaries) or to the direct or indirect holders of Spirit’s or any of its Subsidiaries’ Equity Interests in their capacity as such (other than dividends, distributions or payments payable in Qualifying Equity Interests or in the case of preferred stock of Spirit, an increase in the liquidation value thereof);

(2) purchase, redeem or otherwise acquire or retire for value any Equity Interests of Spirit or any Subsidiary thereof;

(3) make any voluntary payment on or with respect to, or purchase, redeem, defease or otherwise acquire or retire for value (collectively, for purposes of this clause (3), a “purchase”) any Indebtedness of the Co-Issuers or any Guarantor that is contractually subordinated in right of payment to the Notes or the applicable Note Guarantee (excluding any intercompany Indebtedness between or among Spirit and its Subsidiaries), Junior Lien Debt (excluding, for the avoidance of doubt, any payment in respect of Indebtedness outstanding pursuant to Section 4.09(b)(vi)) or unsecured Indebtedness, in each case, except any scheduled payment of interest and any purchase within one year of the scheduled maturity of such Indebtedness; or

(4) make any Restricted Parent Investment;

(all such payments and other actions set forth in these clauses (1) through (4) being collectively referred to as “Restricted Payments”), unless, at the time of and after giving effect to such Restricted Payment, the sum of such Restricted Payment together with the aggregate amount of all other Restricted Payments (other than Restricted Parent Investments) made by Spirit and its Subsidiaries since the Closing Date and together with Restricted Parent Investments outstanding at the time of giving effect to such Restricted Payment (excluding, in each case, Restricted Payments permitted by clauses (ii) through (xxi) of Section 4.07(b) hereof), is less than the sum, without duplication, of:

(i) an amount (which amount shall not be less than zero) equal to 50% of the Consolidated Net Income (less 100% of such Consolidated Net Income which is a deficit) of Spirit for the period (taken as one accounting period) from January 1, 2025 to the end

of Spirit’s most recently ended fiscal quarter for which financial statements are available at the time of such Restricted Payment or Restricted Parent Investment; plus

(ii) 100% of the aggregate net cash proceeds and the Fair Market Value of non-cash consideration received by Spirit after the Closing Date, in each case, as a contribution to its common equity capital or from the issue or sale of Qualifying Equity Interests (other than Qualifying Equity Interests sold to a Subsidiary of Spirit and Excluded Contributions); plus

(iii) 100% of the aggregate net cash proceeds and the Fair Market Value of non-cash consideration received by Spirit from the issue or sale of convertible or exchangeable Disqualified Stock of Spirit or convertible or exchangeable debt securities of Spirit (regardless of when issued or sold) or in connection with the conversion or exchange thereof, in each case that have been converted into or exchanged after the Closing Date for Qualifying Equity Interests of Spirit (other than Qualifying Equity Interests and convertible or exchangeable Disqualified Stock or debt securities sold to a Subsidiary of Spirit); plus

(iv) to the extent that any Restricted Parent Investment that was made after the Closing Date by Spirit is (a) sold for cash or otherwise cancelled, liquidated or repaid for cash, or (b) made in an entity that subsequently becomes a Subsidiary of Spirit, the initial amount of such Restricted Parent Investment (or, if less, the amount of cash received upon repayment or sale);

provided, however, there shall be no increase in respect of any amount contemplated by clause (iv) of this Section 4.08(a) pursuant to any such clause to the extent such amount otherwise increases the capacity of Spirit to make Restricted Payments pursuant to this Section 4.08(a).

(b) The provisions of Section 4.08(a) hereof shall not prohibit:

(i) the payment of any dividend or distribution or the consummation of any irrevocable redemption within 60 days after the date of declaration of the dividend or distribution or giving of the redemption notice, as the case may be, if at the date of declaration or notice, the dividend or distribution or redemption payment would have complied with the other applicable provisions of this Indenture;

(ii) the making of any Restricted Payment in exchange for, or out of or with the net cash proceeds of the substantially concurrent sale (other than to a Subsidiary of Spirit) of, Qualifying Equity Interests or from the substantially concurrent contribution of common equity capital to Spirit; provided that the amount of any such net cash proceeds that are utilized for any such Restricted Payment shall not be considered to be net proceeds of Qualifying Equity Interests for purposes of clause (ii) of Section 4.08(a) hereof and shall not be considered to be Excluded Contributions;

(iii) Restricted SPV Payments by the SPV Parties (A) with amounts released to the Co-Issuers under Section 4.01(j), Section 4.22(e) or pursuant to the terms of the Collateral Agency and Accounts Agreement, in each case, so long as no Event of Default has occurred and is continuing at such time and/or (B) in the form of cash dividends or cash distributions to Spirit solely to the extent necessary for Spirit to pay (x) government fees and other amounts due and owing in respect of maintaining the corporate existence of the SPV Parties and/or (y) any U.S. federal, state or local or non-U.S. income taxes (or any

franchise taxes imposed in lieu thereof) of Spirit to the extent attributable to the income of the SPV Parties, determined by assuming that Spirit is subject to the maximum rate of tax applicable to C corporations;

(iv) the repurchase, redemption, defeasance or other acquisition or retirement for value of Indebtedness of the Co-Issuers or any Guarantor that is contractually subordinated in right of payment to the Notes or to the applicable Note Guarantee with the net cash proceeds from an incurrence of Permitted Refinancing Indebtedness;

(v) Restricted Payment so long as, immediately after giving effect to such payment or declaration, the Total Net Leverage Ratio is less than or equal to 4.00 to 1.00;

If the Trustee provides such a notice, the Co-Issuers shall use their reasonable efforts to resolve the discrepancy and provide an updated Payment Date Statement on or prior to the related Payment Date. If the discrepancy is not resolved and a replacement Payment Date Statement is not received by the Trustee prior to the payment of Available Funds on the related Payment Date pursuant to Section 4.01 and it is later determined that the information identified by the Trustee as incorrect was in fact incorrect and such error resulted in a party receiving a smaller distribution on the Payment Date than they would have received had there not been such an error, then the Co-Issuers shall indemnify such party for such shortfall. For the avoidance of doubt and, notwithstanding anything to the contrary in this Indenture or in any Collateral Document, the Trustee shall have no obligation to inquire into, investigate, verify or perform any calculations in connection with a Payment Date Statement or notice from the Trustee in respect of the same; it being understood and agreed that the Trustee shall be entitled to conclusively rely, and shall not be liable for so relying, on the Payment Date Statement last received by it on or prior to each Payment Date and the Trustee shall have no obligation, responsibility or liability in connection with any indemnification payment of the Co-Issuers pursuant to the immediately preceding sentence;

(b) To the extent not satisfied by this Section 4.17, for so long as any of the Notes remain outstanding during any period when the Reporting Entity is not subject to Section 13 or 15(d) of the

103

Exchange Act, the Co-Issuers shall furnish to Holders, prospective investors and securities analysts, upon the requests of such Holders, prospective investors or securities analysts, any information required to be delivered pursuant to Rule 144A(d)(4) under the Securities Act so long as the Notes are not freely transferable under the Securities Act.

(d) Information required to be delivered pursuant to this Indenture to the Trustee pursuant to Section 4.17(a)(i) through Section 4.17(a)(viii) may be made available by the Trustee to the Holders by posting such information on the Trustee’s website on the Internet at http://wilmingtontrustconnect.com. Information required to be delivered pursuant to this Indenture shall be deemed to have been delivered to the Trustee on the date on which Spirit provides written notice to the Trustee that such information has been posted on Spirit’s general commercial website on the Internet (to the extent such information has been posted or is available as described in such notice), as such website may be specified by Spirit to the Trustee from time to time, and shall be in a format which is suitable for transmission.

(e) Delivery of reports, information, appraisals, and documents to the Trustee is for informational purposes only and its receipt of such reports, information, appraisals, and documents shall not constitute constructive notice of any information contained therein or determinable from information contained therein, including compliance by any Co-Issuer, Guarantor or any other Person with any of its covenants under this Indenture or the Notes (as to which the Trustee is entitled to rely exclusively on Officer’s Certificates). The Trustee shall have no liability or responsibility for the content, filing or timeliness of any report, appraisal, or other information delivered, filed or posted under or in connection with this Indenture, the other Transaction Documents or the transactions contemplated thereunder. The Trustee has no duty to monitor or confirm, on a continuing basis or otherwise, the Obligors’ compliance with this Article 4 or with respect to matters disclosed in any reports or other documents filed with the SEC or EDGAR or any website under this Indenture, or participate in any conference calls.

(f) The financial statements, information and other documents required to be provided as described in Sections 4.17(a)(i), 4.17(a)(ii), 4.17(b), 4.17(d) and 4.17(e) may be those of (i) Spirit or (ii) any direct or indirect parent of Spirit, including the Holdco Guarantor (any such entity described in clause (i) or (ii) that provides such financial statements, information or other documents, the “Reporting Entity”), so long as, in the case of clause (ii), such direct or indirect parent of Spirit shall comply Section 4.36 or (2) the financial information so delivered shall be accompanied by a reasonably detailed description of the quantitative differences between the information relating to such parent, on the one hand, and the information relating to Spirit and its Subsidiaries on a standalone basis, on the other hand.

(b) its and its Subsidiaries’ rights (charter and statutory) and material franchises; provided, however, that Spirit shall not be required to preserve any such right or franchise, or the corporate, partnership or other existence of it or any of its Subsidiaries (other than any SPV Party), if its Board of Directors shall determine that the preservation thereof is no longer desirable in the conduct of the business of Spirit and its Subsidiaries, taken as a whole, and that the loss thereof would not, individually or in the aggregate, have a Material Adverse Effect.

For the avoidance of doubt, this Section 4.18 shall not prohibit any actions permitted by Article 5.

Section 4.19 Use of Proceeds.

Spirit will not use, and will not permit any of its Subsidiaries to use, the proceeds of the Notes (A) in violation of any Anti-Corruption Laws, (B) for the purpose of funding, financing or facilitating any activities, business or transaction of or with any Sanctioned Person, or in any Sanctioned Country (except to the extent permitted by applicable law), or (C) in any manner that would result in the violation of any Sanctions applicable to Spirit or any of its Subsidiaries.

(a) The Obligors shall not terminate, amend, waive, supplement or otherwise modify any IP Agreement or any provision thereof or exercise any right or remedy under or pursuant to or under any IP Agreement, in each case without the prior written consent of the Required Debtholders if such termination, amendment, waiver, supplement or modification or exercise of remedies would reasonably be expected to result in a Material Adverse Effect; provided that (i) termination of any IP Agreement or any amendment to the termination provisions thereof, or (ii) any amendment to an IP Agreement that (A) materially and adversely affects rights to the Loyalty Program Intellectual Property, Brand Intellectual Property or, in the case of the Contribution Agreements, other applicable Collateral, or rights to use Loyalty Program Intellectual Property, Brand Intellectual Property or, in the case of the Contribution Agreements, other applicable Collateral, (B) shortens the scheduled term thereof, (C) in the case of any IP License, materially and adversely changes the amount or calculation of the termination payment, or the amount, calculation or rate of fees due and owing thereunder, (D) changes the contractual subordination of payments thereunder in a manner materially adverse to the Senior Secured Parties, (E) reduces the frequency of payments thereunder to an SPV Party or permits payments due to an SPV Party thereunder to be deposited to an account other than a Collection Account, (F) changes the amendment standards applicable to such IP Agreement (other than changes affecting rights of the Trustee or the Collateral Agent to consent to amendments, which is covered by clause (G)) in a manner that would reasonably be expected to result in a Material Adverse Effect or (G) materially impairs the rights of the Trustee or the Collateral Agent to enforce or consent to amendments to any provisions thereof in accordance therewith shall, in each case, be deemed to have a Material Adverse Effect.

105

(b) Any assignment, pursuant to a Contribution Agreement, of Intellectual Property registered in the United States shall be filed in the applicable intellectual property office and applicable internet domain name registrars on or before the date that is thirty (30) days after the Closing Date (as extendable automatically without consent of the Trustee to the extent the Co-Issuers are diligently pursuing satisfaction of the terms hereof, but such completion has been delayed as a result of the COVID-19 pandemic or other events and conditions (e.g., natural disaster), which are outside the control of the Obligors).

Section 4.22 Required Excess Cash Flow Repurchase Offers.

(a) On each Payment Date, if a Cash Trap Period is in effect as of the last day of the related Quarterly Reporting Period and a Cash Trap Cure has not occurred on or prior to such Payment Date, then the Co-Issuers, in the Payment Date Statement, shall direct the Trustee to deposit any Required Excess Cash Flow for such Payment Date to the ECF Account pursuant to Section 4.01. Within 30 days of any such Payment Date, the Co-Issuers shall make an offer (an “ECF Repurchase Offer”) to all Holders to purchase the maximum principal amount of Notes on a pro rata basis that may be purchased out of such Required Excess Cash Flow at a repurchase price equal to 100.0% of the principal amount of the Notes to be repurchased, plus accrued and unpaid interest thereon to, but excluding, the ECF Repurchase Date (as defined below).

(b) The ECF Repurchase Offer shall remain open for a period of 20 Business Days following its commencement and no longer, except to the extent that a longer period is required by applicable law (the “ECF Repurchase Offer Period”). Promptly after the expiration of the ECF Repurchase Offer Period (the “ECF Repurchase Date”), the Trustee shall apply all of the Required Excess Cash Flow to effect the repurchase by the Co-Issuers of all of the Notes tendered in the ECF Repurchase Offer at a repurchase price equal to 100.0% of the principal amount of the Notes to be repurchased, plus accrued and unpaid interest thereon to, but excluding, the ECF Repurchase Date (the “ECF Offer Repurchase Price”); provided that if the aggregate ECF Offer Repurchase Price for all Notes tendered in such ECF Repurchase Offer exceeds the total amount of Required Excess Cash Flow, then such tendered Notes shall be repurchased pro rata up to the maximum amount of Notes that can be repurchased with such Required Excess Cash Flow.

(c) If the ECF Repurchase Date is on or after a record date and on or before the related Payment Date, any accrued and unpaid interest up to but excluding the ECF Repurchase Date, shall 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 shall be payable to Holders who tender Notes pursuant to the ECF Repurchase Offer.

(d) Notices of an ECF Repurchase Offer (“ECF Repurchase Offer Notices”) shall be sent by the Co-Issuers by first class mail or sent electronically, no later than 30 days after the applicable Payment Date, to each Holder at such Holder’s registered address or otherwise in accordance with the

106

applicable procedures of DTC. ECF Repurchase Offer Notices shall contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the ECF Repurchase Offer. The ECF Repurchase Offer shall be made to all Holders. The ECF Repurchase Offer Notice, which shall govern the terms of the ECF Repurchase Offer, shall state:

(i) that the ECF Repurchase Offer is being made pursuant to this Section 4.22 and the length of time the ECF Repurchase Offer shall remain open;

(ii) the Required Excess Cash Flow for such Payment Date, the repurchase price and the ECF Repurchase Date;

(iii) that any Note not tendered or accepted for payment shall continue to accrue interest;

(iv) that, unless the Co-Issuers default in making such payment, any Note accepted for payment pursuant to the ECF Repurchase Offer shall cease to accrue interest after the ECF Repurchase Date;

(v) that Holders electing to have a Note purchased pursuant to an ECF Repurchase Offer may elect to have Notes purchased in minimum amounts of $1.00 or integral multiples of $1.00 in excess thereof only;

(vi) that Holders electing to have a Note purchased pursuant to any ECF Repurchase Offer shall be required to surrender the Note, with the form entitled “Option of Holder to Elect Purchase” attached to the Note completed, or transfer by book-entry transfer, to the Co-Issuers, the Notes Depositary, if appointed by the Co-Issuers, or a Paying Agent at the address specified in the notice at least two (2) Business Days before the ECF Repurchase Date;

(vii) that Holders shall be entitled to withdraw their election if the Co-Issuers, the Notes Depositary or the Paying Agent, as the case may be, receives, not later than the expiration of the ECF Repurchase Offer Period, a facsimile or other electronic transmission or letter setting forth the name of the Holder, the principal amount of the Notes the Holder delivered for purchase and a statement that such Holder is withdrawing his election to have such Notes purchased;

(viii) that, if the aggregate principal amount of Notes surrendered by the Holders thereof exceeds the amount that can be repurchased with the Required Excess Cash Flow for such Payment Date, the Trustee shall select the Notes (while the Notes are in global form pursuant to the procedures of the Notes Depositary) to be purchased on a pro rata basis based on the principal amount of the Notes tendered (with such adjustments as may be deemed appropriate by the Co-Issuers so that only Notes in denominations of $1.00, or integral multiples of $1.00 in excess thereof, shall remain outstanding after such purchase) to the extent practicable, or, if the pro rata basis is not practicable for any reason, by lot or by such other method as most nearly approximates a pro rata basis subject to customary procedures of the Notes Depositary; and

107

(e) To the extent that the aggregate principal amount of Notes validly tendered or otherwise surrendered in connection with an ECF Repurchase Offer is less than the Required Excess Cash Flow, the Co-Issuers may, after purchasing all such Notes validly tendered and not withdrawn, use the remaining Required Excess Cash Flow for any purpose not otherwise prohibited by this Indenture. If the aggregate principal amount of the Notes validly tendered pursuant to any ECF Repurchase Offer exceeds the Required Excess Cash Flow, the Co-Issuers will allocate the Required Excess Cash Flow to purchase Notes on a pro rata basis on the basis of the aggregate principal amount of tendered Notes; provided that no Notes will be selected and purchased in an unauthorized denomination. Upon completion of any repurchase of Notes in an ECF Repurchase Offer, the amount of Required Excess Cash Flow shall be reset at zero.

(f) On or before the ECF Repurchase Date, the Co-Issuers shall, to the extent lawful, (1) accept for payment, on a pro rata basis to the extent necessary, the Notes or portions thereof validly tendered pursuant to the ECF Repurchase Offer, or if the aggregate ECF Offer Repurchase Price for all Notes so tendered in such ECF Repurchase Offer does not exceed the total amount of Required Excess Cash Flow, all Notes tendered and (2) deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officer’s Certificate stating the aggregate principal amount of Notes or portions thereof so tendered.

(g) The Trustee, the Notes Depositary or the Paying Agent, as the case may be, shall promptly mail or deliver to each tendering Holder from amounts held in the ECF Account an amount equal to the repurchase price of the Notes properly tendered by such Holder and accepted by the Co-Issuers for repurchase, and the Co-Issuers shall promptly issue a new Note, and the Trustee, upon receipt of an Authentication Order, shall authenticate and mail or deliver (or cause to be transferred by book-entry) such new Note to such Holder (it being understood that, notwithstanding anything in this Indenture to the contrary, no Opinion of Counsel or Officer’s Certificate is required for the Trustee to authenticate and mail or deliver such new Note) in a principal amount equal to any unpurchased portion of the Note surrendered representing the same indebtedness to the extent not repurchased; provided, that each such new Note shall be in a minimum denomination of $1.00 or an integral multiple of $1.00 in excess thereof. Any Note not so accepted shall be promptly mailed or delivered by the Co-Issuers to the Holder thereof. The Co-Issuers shall publicly announce the results of the ECF Repurchase Offer on or as soon as practicable after the ECF Repurchase Date.

(h) The Co-Issuers will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of an ECF Repurchase Offer. To the extent that the provisions of any securities laws or regulations, including Rule 14e-1 under the Exchange Act, conflict with the provisions of this Indenture, the Co-Issuers shall not be deemed to have breached its obligations described in this Indenture by virtue of compliance therewith.

Section 4.23 Offer to Repurchase Upon Parent Change of Control.

(a) If a Parent Change of Control occurs, each Holder of Notes will have the right to require the Co-Issuers to repurchase all or any part of that Holder’s Notes pursuant to an offer (a “Parent Change of Control Offer”) at a purchase price in cash equal to 101% of the aggregate principal amount of Notes repurchased, plus accrued and unpaid interest on the Notes repurchased to the date of repurchase (the “Parent Change of Control Payment”), subject to the rights of Holders of Notes on the relevant record date to receive interest due on the relevant Payment Date. Within thirty (30) days following any Parent Change of Control, the Co-Issuers will mail or send electronically pursuant to applicable DTC procedures a notice to each Holder and the Trustee describing the transaction or transactions that constitute the Parent Change of Control and offering to repurchase Notes on the date specified in the notice (the “Parent Change of

108

Control Payment Date”), which date will be no earlier than thirty (30) days and no later than sixty (60) days from the date such notice is mailed or sent, pursuant to the procedures required by this Indenture and described in such notice and stating:

(i) that the Parent Change of Control Offer is being made pursuant to this Section 4.23 and that all Notes tendered will be accepted for payment;

(ii) the purchase price and the Parent Change of Control Payment Date, which shall be no earlier than 30 days and no later than 60 days from the date such notice is mailed or sent;

(iii) that any Note not tendered will continue to accrue interest;

(iv) that, unless the Co-Issuers default in the payment of the Parent Change of Control Payment, all Notes accepted for payment pursuant to the Parent Change of Control Offer will cease to accrue interest after the Parent Change of Control Payment Date;

(v) that Holders of Notes electing to have any Notes purchased pursuant to a Parent Change of Control Offer will be required to surrender the Notes, with the form entitled “Option of Holder to Elect Purchase” attached to the Notes completed, or transfer such Notes by book-entry transfer, to the Paying Agent at the address specified in the notice prior to the close of business on the third Business Day preceding the Parent Change of Control Payment Date; and

(vi) that Holders of Notes will be entitled to withdraw their election if the Paying Agent receives, not later than the close of business on the second Business Day preceding the Parent Change of Control Payment Date, a facsimile or other electronic transmission or letter setting forth the name of the Holder, the principal amount of Notes delivered for purchase, and a statement that such Holder is withdrawing its election to have the Notes purchased.

The Co-Issuers will provide a copy of such notice to the Trustee.

The Co-Issuers will comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes as a result of a Parent Change of Control. To the extent that the provisions of any securities laws or regulations conflict with the provisions of this Section 4.23, the Co-Issuers will comply with the applicable securities laws and regulations and will not be deemed to have breached its obligations under this Section 4.23 by virtue of such compliance.

(b) On the Parent Change of Control Payment Date, the Co-Issuers will, to the extent lawful:

(i) accept for payment all Notes or portions of Notes properly tendered pursuant to the Parent Change of Control Offer;

(ii) deposit with the paying agent an amount equal to the Parent Change of Control Payment in respect of all Notes or portions of Notes properly tendered; and

109

(iii) deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officer’s Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased by the Co-Issuers.

(c) The paying agent will promptly mail or otherwise pay in accordance with this Indenture and applicable DTC procedures to each Holder of Notes properly tendered the Parent Change of Control Payment for the Notes, and the Co-Issuers will issue and the Trustee will promptly authenticate and mail (or cause to be transferred by book entry) to each Holder a new note equal in principal amount to any unpurchased portion of the Notes surrendered, if any.

(d) The provisions of this Section 4.23 that require the Co-Issuers to make a Parent Change of Control Offer following a Parent Change of Control will be applicable whether or not any other provisions of this Indenture are applicable.

(e) The Co-Issuers will not be required to make a Parent Change of Control Offer upon a Parent Change of Control if (1) a third party makes the Parent 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 Parent Change of Control Offer made by the Co-Issuers and purchases all Notes properly tendered and not withdrawn under the Parent Change of Control Offer, or (2) notice of redemption with respect to all Notes has been given pursuant to Section 3.07 unless and until there is a default in payment of the applicable redemption price; and a Parent Change of Control Offer may be made in advance of a Parent Change of Control, conditioned upon the consummation of such Parent Change of Control, if a definitive agreement is in place for the Parent Change of Control at the time the Parent Change of Control Offer is made. If a Parent Change of Control occurs at a time when the Co-Issuers are prohibited, by the terms of any of their indebtedness, from purchasing the Notes, the Co-Issuers may seek the consent of their lenders to the purchase of the Notes or may attempt to refinance the borrowings that contain such prohibition. If the Co-Issuers do not obtain such a consent or repay such borrowings, they would remain prohibited from purchasing the Notes. In such case, the Co-Issuers’ failure to offer to purchase the Notes shall constitute an Event of Default under this Indenture. For the avoidance of doubt, the Co-Issuers’ failure to offer to purchase the Notes shall constitute an Event of Default under Section 6.02(a)(iii) and not Section 6.02(a)(i), but the failure of the Co-Issuers to pay the Parent Change of Control Payment when due shall constitute an Event of Default under Section 6.02(a)(i).

(f) If Holders of not less than 90% in aggregate principal amount of the outstanding Notes validly tender and do not withdraw the Notes in a Parent Change of Control Offer and the Co-Issuers, or any third party making a Parent Change of Control Offer in lieu of the Co-Issuers, purchase all of such Notes validly tendered and not withdrawn by such Holders, the Co-Issuers will have the right, upon not less than twenty (20) nor more than sixty (60) days’ prior notice, given not more than thirty (30) days following such purchase pursuant to the Parent Change of Control Offer described above, to redeem all Notes that remain outstanding following such purchase at a redemption price in cash equal to 101% of the principal amount thereof, plus accrued and unpaid interest thereon, if any, to but not including the date of redemption (subject to the right of Holders of record on the relevant record date to receive interest on the relevant interest payment date).

Section 4.24 Maintenance of Office or Agency.

(a) The Co-Issuers shall maintain an office or agency (which may be an office of the Trustee or an affiliate of the Trustee, Registrar or co-registrar) where Notes may be surrendered for registration of transfer or for exchange and where notices and demands to or upon the Co-Issuers in respect of the Notes and this Indenture may be served. The Co-Issuers shall give prompt written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Co-

110

Issuers shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made at the Corporate Trust Office of the Trustee.

(b) The Co-Issuers may also from time to time designate one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, that no such designation or rescission shall in any manner relieve the Co-Issuers of their obligation to maintain an office or agency for such purposes. The Co-Issuers shall give prompt written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency.

(c) The Co-Issuers hereby designate the Corporate Trust Office of the Trustee as one such office or agency of the Co-Issuers in accordance with Section 2.03 hereof; provided, that no service of legal process on the Co-Issuers or any Guarantor may be made at any office of the Trustee.

Section 4.25 Taxes.

Each Obligor shall pay, and cause each of its Subsidiaries to pay, all material taxes, assessments, and governmental levies before the same shall become more than ninety (90) days delinquent, other than taxes, assessments and levies (i) being contested in good faith by appropriate proceedings and (ii) the failure to effect such payment of which are not reasonably expected to have a Material Adverse Effect.

Section 4.26 Stay, Extension and Usury Laws.

Each Obligor covenants (to the extent that it may lawfully do so) that it will 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 in or the performance of this Indenture; and each Obligor (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law, and covenants that it will not, by resort to any such law, hinder, delay or impede the execution of any power herein granted to the Trustee or the Collateral Agent, but will suffer and permit the execution of every such power as though no such law has been enacted.

Section 4.27 Compliance with Laws.

Spirit shall comply, and cause each of its Subsidiaries to comply, with all applicable laws, rules, regulations and orders of any Governmental Authority applicable to it or its property, except where such noncompliance, individually or in the aggregate, would not reasonably be expected to result in a Material Adverse Effect. Without limiting the foregoing, Spirit will maintain in effect policies and procedures intended to ensure compliance by Spirit, its Subsidiaries and, when acting in such capacity, their respective directors, officers, employees and agents with Anti-Corruption Laws and applicable Sanctions.

Section 4.30 Further Assurances.

(a) In each case, subject to the terms, conditions and limitations in the Notes Documents, each Co-Issuer and other Guarantor shall execute any and all further documents and instruments, and take all further actions, that may be required or advisable under applicable law or that the Collateral Agent may reasonably request, in order to create, grant, establish, preserve, protect and perfect the validity, perfection and priority of the Liens and security interests created or intended to be created by the Collateral Documents, including but not limited to making entries in the registers of mortgages and charges of each Co-Issuer and Cayman Guarantor maintained at its registered office, in each case to the extent required under this Indenture or the Collateral Documents.

(b) [Reserved.]

(c) Pursuant to the Notes Documents, and subject to certain limitations herein and therein, Spirit may identify one or more co-branding, partnering or similar agreements related to or entered into in connection with the Free Spirit Program to constitute “Retained Agreements,” provided that the

112

aggregate amount of Retained Agreement Revenues over the preceding four Quarterly Reporting Periods (or, in the case of the first three Quarterly Reporting Periods, since the Closing Date) must be less than 5.0% of the Free Spirit Program Revenues over the same period. If the aggregate amount of Retained Agreement Revenues in any applicable test period (determined on each Determination Date) is greater than or equal to 5.0% of the Free Spirit Program Revenues over such period, Spirit shall promptly assign the payment rights under one or more Retained Agreements to the Loyalty Issuer such that the aggregate amount of revenues produced by the Retained Agreements not so assigned is less than 5.0% of the Free Spirit Program Revenues in such period on a pro forma basis. All of the Loyalty Issuer’s rights under the Retained Agreements assigned to it shall be pledged as Collateral on a first lien basis and each such assigned Retained Agreement shall thereafter be a Free Spirit Agreement and not a Retained Agreement. The terms of each Free Spirit Agreement entered into following the Closing Date will provide that (i) the counterparty thereto will deposit all payments directly into the Loyalty Collection Account, (ii) acknowledge and agree to the assignment of all payment rights thereunder to the Loyalty Issuer and (iii) consent to the pledge of the Obligors’ rights, title and interest in such agreement as the Collateral.

(d) Promptly after the date upon which it is permissible to transfer and assign any Specified IP, Spirit and the Cayman Guarantors shall, if such Specified IP is not transferred and assigned pursuant to an existing Contribution Agreement, execute and deliver one or more Contribution Agreements together with all further documents and instruments that may be required and advisable, and take all further actions that may be required or advisable under applicable law or that the Collateral Agent may reasonably request, to transfer and assign all of such Guarantors’ right, title and interest in and to such Specified IP to the applicable Co-Issuer, and shall promptly provide the Trustee and the Collateral Agent copies of any such documents.

(e) If Spirit or any other Grantor acquires or creates another Subsidiary after the Closing Date, then Spirit will promptly cause such Subsidiary to become a Guarantor by executing and delivering a supplemental indenture to this Indenture, the form of which is attached as Exhibit D hereto; provided, that any Subsidiary that is not a Material Subsidiary or that is an Excluded Subsidiary need not become a Guarantor unless and until 30 days after such time as it becomes a Material Subsidiary or ceases to be an Excluded Subsidiary or such time as it guarantees, or pledges any property or assets to secure, any other Material Indebtedness of Spirit or any of its other Subsidiaries.

(f) If (x) Spirit or any other Grantor acquires any other assets that are not Excluded Property or (y) any Subsidiary becomes a Guarantor, Spirit shall, in each case, promptly (and in any event within forty-five (45) days of the acquisition of such assets or such Subsidiary becoming a Guarantor, as applicable) and at its own expense:

(A) cause Spirit or any such Subsidiary to become a party to each applicable Collateral Document and all other agreements, instruments or documents that create or purport to create and perfect a first priority Lien (subject to Permitted Liens, including, in the case of any Revolving Priority Collateral, the first priority Lien securing any Credit Facility incurred pursuant to Section 4.09(b)(vi) that is senior to the Lien thereon securing the Notes) in favor of the Collateral Agent, by executing and delivering to the Collateral Agent joinders to all applicable Collateral Documents or pursuant to new Collateral Documents, as the case may be, in substantially the same form as the Collateral Documents or the joinders to the Collateral Documents, as applicable, delivered on or about the Closing Date, it being understood that:

(i) shall not apply to any cash or Cash Equivalents of a SPV Party or any deposit account or securities account in the name of any SPV Party);

in the case of Flight Simulators, acquired by Spirit or any Subsidiary thereof after the Closing Date (other than Flight Simulators located on Pledged Real Property Assets or on Material Real Property Assets subject to the terms and conditions of Section 4.34), Spirit shall file UCC-1 fixture filings in the real property records in the county in which such Flight Simulators are located;

(vi)

in the case of Titled Ground Support Equipment, the applicable Grantor shall (x) submit all required applications and documentation to the applicable government authority to record the Collateral Agent’s security interest on such certificate of title (or local equivalent), (y) deliver an original or certified copy of such certificates of title (or local equivalent) to the Collateral Agent or its designated agent and (z) provide evidence confirming that the Collateral Agent’s security interest therein has been duly recorded in the jurisdiction where the certificate of title (or local equivalent) is registered; provided that Spirit shall, on a semi-annual basis of each calendar year, cause all Titled Ground Support Equipment that is not subject to a perfected Lien in favor of the Collateral Agent at such time to become subject to a perfected Lien in favor of the Collateral Agent pursuant to this sub-clause (vi);

(vii)

in the case of Material Real Property Assets, such assets shall be subject to the terms and conditions of Section 4.34; and

(viii)

in the case of any other assets of a type that is not already included in the Collateral (other than Aircraft, Engines, Spare Parts, Slots, Gate Leaseholds and Real Property Assets), such assets may be subject to such additional terms and conditions to the extent necessary to perfect Liens thereon in favor of the Collateral Agent and as may be customarily required by lenders or creditors in similar financings of a similar size for similarly situated borrowers or issuers secured by the same type of Collateral, in each case, as determined by Spirit in good faith;

(B) execute and deliver (or cause such Subsidiary to execute and deliver) to the Trustee and/or the Collateral Agent such documents and take such actions to create, grant, establish, preserve and perfect the first priority Liens (subject to Permitted Liens, including, in the case of any Revolving Priority Collateral, the first priority Lien securing any Credit Facility incurred pursuant to Section 4.09(b)(vi) that is senior to the Lien securing the Notes) in favor of the Collateral Agent for the benefit of the Senior Secured Parties on such assets of Spirit or such Subsidiary, as applicable, to secure the Obligations to the extent required under the applicable Collateral Documents or reasonably requested by the Trustee, the Collateral Agent or the Required

114

Debtholders, and to cause such Collateral to not be subject to any other Liens other than Permitted Liens; and

(C) if reasonably requested by the Required Debtholders, deliver to the Trustee and the Collateral Agent, for the benefit of the Senior Secured Parties, a written opinion of appropriate counsel to Spirit or such Subsidiary, as applicable, with respect to the matters described in the foregoing clauses (A) and (B), in each case within twenty (20) Business Days after the addition of such Collateral, which written opinion shall be reasonably satisfactory to counsel to the Required Debtholders.

(c) with respect to each Real Property Mortgage, either a bringdown of an existing title policy or a loan policy of title insurance (or marked up title insurance commitment having the effect of a loan policy of title insurance) insuring the Lien of such Real Property Mortgage as a valid first mortgage Lien on the Pledged Real Property Asset in an appropriate amount based on similar financings of a similar size for similarly situated borrowers or issuers secured by the same type of Collateral (as determined by Spirit in good faith) not to exceed the Fair Market Value of such Pledged Real Property Asset (subject to Permitted Liens), which policy (or such marked-up commitment) (each, a “Title Policy”) shall (A) be issued by a Title Company, (B) to the extent necessary and available, include such reinsurance arrangements (with provisions for direct access, if necessary) as shall be reasonably acceptable to counsel to the Required Debtholders, (C) contain a “tie-in” or “cluster” endorsement, if available under applicable law (i.e., policies which insure against losses regardless of location or allocated value of the insured property up to a stated maximum coverage amount), (D) have been supplemented by such customary endorsements (if available in the applicable jurisdiction of the Pledged Real Property Asset) as shall be reasonably requested by the Required Debtholders (including endorsements on matters relating to usury, first loss, zoning, contiguity, revolving credit, doing business, public road access, survey, variable rate, environmental lien, subdivision, mortgage recording tax, separate tax lot, and so-called comprehensive coverage over covenants and restrictions); provided that to the extent that any such endorsement(s) or other documentation cannot be issued or is not available due to the state or condition of the Pledged Real Property Asset, and such state or condition existed on the date of the pledge of such Pledged Real Property Asset and such state or condition does not materially and adversely affect the use or the value of such Pledged Real Property Asset for the business of Spirit and its Affiliates, Spirit shall have no obligation to procure such endorsement or other documentation, and (E) contain no exceptions to title other than Permitted Liens and other

116

exceptions reasonably acceptable to counsel to the Required Debtholders or a datedown endorsement on the existing Title Policy for each existing Real Property Mortgage;

The Permitted Noteholders by 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, principal and premium, if any, on any Note held by a non-consenting Holder; provided, that subject to Section 6.03 hereof, the Permitted Noteholders may rescind an acceleration and its consequences, including any related payment default that resulted from such acceleration.

Section 6.05 Control by Majority.

The Holders of a majority in principal amount of the outstanding Notes may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee with respect to the Notes. However, the Trustee may refuse to follow any direction that conflicts with law or this Indenture or that, subject to Section 7.01, the Trustee determines is unduly prejudicial to the rights of any other Holder of a Note or that would subject the Trustee to personal liability; provided, however that the Trustee has no duty to determine whether any such action is prejudicial to any Holder or beneficial owner of the Notes.

Section 6.06 Limitation on Suits.

(v) the Permitted Noteholders have not given the Trustee a direction inconsistent with such request within such 60-day period.

126

Notwithstanding any other provision of this Indenture, the right of any Holder of a Note to receive payment of principal, interest and premium, if any, on the Notes, on or after the respective due dates expressed in the Note (including in connection with a Mandatory Repurchase Offer, ECF Repurchase Offer, or a Parent Change of Control Offer), or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder.

Section 6.08 Collection Suit by Trustee.

If an Event of Default specified in Section 6.02(a)(i) hereof occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Co-Issuers for the whole amount of interest remaining unpaid, principal and premium, if any, on the Notes and interest on overdue principal and, to the extent lawful, interest and 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 6.09 Restoration of Rights and Remedies.

Section 6.10 Rights and Remedies Cumulative.

Except as otherwise provided with respect to the replacement or payment of mutilated, destroyed, lost or stolen Notes in Section 2.07 hereof, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

Section 6.11 Delay or Omission Not Waiver.

No delay or omission of the Trustee or of any Holder of any Note to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article 6 or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be.

Section 6.12 Trustee May File Proofs of Claim.

To the extent that the payment of any such compensation, expenses, disbursements and advances of the Trustee, the Collateral Custodian, their agents and counsel, and any other amounts due the Trustee under Section 7.07 hereof 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 herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the 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 6.13 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 Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys’ fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.13 does not apply to a suit by the Trustee, a suit by a Holder of a Note pursuant to Section 6.07 hereof, or a suit by Holders of more than 10.0% in principal amount of the then outstanding Notes.

(t) The Trustee shall be fully justified in failing or refusing to take any action under this Indenture or any other related document if such action (A) would, in the reasonable opinion of the Trustee, in good faith (which may be based on the advice or opinion of counsel), be contrary to applicable law, this Indenture or any other related document, or (B) is not provided for in this Indenture or any other related document.

Section 7.03 Individual Rights of Trustee.

The Trustee in its individual or any other capacity may become the owner or pledgee of Notes and may otherwise deal with the Co-Issuers or any Affiliate of the Co-Issuers with the same rights it would have if it were not Trustee.

Section 7.06 [Reserved.]

Section 7.07 Compensation and Indemnity.

(a) The Co-Issuers shall pay to the Trustee and Collateral Custodian from time to time such compensation for its acceptance of this Indenture and services hereunder as the parties shall agree in

132

writing from time to time. Neither the Trustee’s nor Collateral Custodian’s compensation shall be limited by any law on compensation of a trustee of an express trust.

The Trustee or Collateral Custodian, as applicable, shall notify the Co-Issuers promptly of any claim for which it may seek indemnity. Failure by the Trustee or Collateral Custodian, as applicable, to so notify the Co-Issuers shall not relieve the Co-Issuers of their obligations hereunder. The Co-Issuers shall defend the claim and the Trustee and Collateral Custodian may have separate counsel and the Co-Issuers shall pay the fees and expenses of such counsel. The Co-Issuers need not reimburse any expense or indemnify against any loss, liability or expense incurred by the Trustee or Collateral Custodian through the Trustee’s or Collateral Custodian’s, respectively, own willful misconduct or gross negligence.

(c) The obligations of the Co-Issuers and the Guarantors under this Section 7.07 shall survive the satisfaction and discharge of this Indenture or the earlier resignation or removal of the Trustee or Collateral Custodian.

Article 8

LEGAL DEFEASANCE AND COVENANT DEFEASANCE

Section 8.01 Option to Effect Legal Defeasance or Covenant Defeasance.

The Co-Issuers may, at their option and at any time, elect to have either Section 8.02 or Section 8.03 hereof applied to all outstanding Notes upon compliance with the conditions set forth below in this Article 8.

Section 8.02 Legal Defeasance and Discharge.

(a) Upon the Co-Issuers’ exercise under Section 8.01 hereof of the option applicable to this Section 8.02, the Co-Issuers and the Guarantors shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be deemed to have been discharged from their obligations with respect to all outstanding Notes and Note Guarantees on the date the conditions set forth below are satisfied (“Legal Defeasance”). For this purpose, Legal Defeasance means that the Co-Issuers shall be deemed to have paid and discharged the entire Indebtedness represented by the outstanding Notes, which shall thereafter be deemed to be “outstanding” only for the purposes of Section 8.05 hereof and the other Sections of this Indenture referred to in this Section 8.02(a) and Section 8.02(b), and to have satisfied all its other obligations under such Notes and this Indenture including that of the Guarantors (and the Trustee, on demand of and at the expense of the Co-Issuers, shall execute such instruments reasonably requested by the Co-Issuers acknowledging the same), except for the following provisions which shall survive until otherwise terminated or discharged hereunder:

(i) the rights of Holders of Notes to receive payments in respect of the interest, principal and premium, if any, on the Notes when such payments are due solely out of the trust created pursuant to this Indenture referred to in Section 8.04 hereof;

(ii) the Co-Issuers’ obligations with respect to Notes concerning issuing temporary Notes, registration of such Notes, mutilated, destroyed, lost or stolen Notes and the maintenance of an office or agency for payment and money for security payments held in trust;

(iii) the rights, powers, trusts, duties and immunities of the Trustee, and the Co-Issuers’ obligations in connection therewith; and

Upon the Co-Issuers’ exercise under Section 8.01 hereof of the option applicable to this Section 8.03, the Co-Issuers and the Guarantors shall, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, be released from their obligations under Section 4.06 through Section 4.17, Section 4.19 through Section 4.21, Section 4.27 through Section 4.35 and Section 5.01 (except for Section 5.01(a)(i)

135

and (ii) and Section 5.01(d)) hereof with respect to the outstanding Notes on and after the date the conditions set forth in Section 8.04 hereof are satisfied (“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 may not be deemed outstanding for accounting purposes). For this purpose, Covenant Defeasance means that, with respect to the outstanding Notes, the Co-Issuers 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 or an Event of Default under Section 6.02 hereof, but, except as specified above, the remainder of this Indenture and such Notes shall be unaffected thereby. In addition, upon the Co-Issuers’ exercise under Section 8.01 hereof of the option applicable to this Section 8.03, subject to the satisfaction of the conditions set forth in Section 8.04 hereof, Section 6.02(a)(ii) (solely with respect to the defeased covenants listed above), Section 6.02(a)(iii) (solely with respect to the defeased covenants listed above) or Section 6.02(a)(iv) (solely with respect to the defeased covenants listed above) hereof shall not constitute Events of Default.

Section 8.04 Conditions to Legal or Covenant Defeasance.

The following shall be the conditions to the application of either Section 8.02 or Section 8.03 hereof to the outstanding Notes:

(a) the Co-Issuers must irrevocably deposit with the Trustee, in trust, for the benefit of the Holders of the Notes, cash in U.S. dollars, non-callable U.S. Government Securities, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized independent registered public accounting firm, to pay the principal of, premium, if any, and interest on the outstanding Notes on the stated date for payment thereof or on the applicable redemption date, as the case may be;

136

(d) such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under, any material agreement or instrument (other than this Indenture) to which any Co-Issuer is a party or by which any Co-Issuer is bound;

(e) the Co-Issuers shall have delivered to the Trustee an Officer’s Certificate stating that the deposit was not made by the Co-Issuers with the intent of preferring Holders over any other creditors of the Co-Issuers or with the intent of defeating, hindering, delaying or defrauding any other creditors of the Co-Issuers or others;

(f) the Co-Issuers shall have delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel each stating that all conditions precedent provided for or relating to the Legal Defeasance or the Covenant Defeasance, as the case may be, have been complied with; and

Section 8.05 Deposited Money and Government Securities to Be Held in Trust; Other Miscellaneous Provisions.

(a) Subject to Section 8.06 hereof, all money and Government Securities (including the proceeds thereof) deposited with the Trustee (or other qualifying trustee, collectively for purposes of this Section 8.05, the “Trustee”) pursuant to Section 8.04 hereof in respect of the outstanding Notes shall be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent (including the Co-Issuers or a Guarantor acting as Paying Agent) as the Trustee may determine, to the Holders of such Notes of all sums due and to become due thereon in respect of interest, principal and premium, if any, on the Note, but such money need not be segregated from other funds except to the extent required by law.

(c) Anything in this Article 8 to the contrary notwithstanding, the Trustee shall deliver or pay to the Co-Issuers from time to time upon the request of the Co-Issuers any money or Government Securities held by it as provided in Section 8.04 hereof which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee (which may be the opinion delivered under Section 8.04 hereof), are in excess of the amount thereof that would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance.

Section 8.06 Repayment to Co-Issuers.

Subject to applicable abandoned property law, any money deposited with the Trustee or any Paying Agent, or then held by the Co-Issuers, in trust for the payment of the interest, principal and premium, if any, on any Note and remaining unclaimed for two years after such interest, principal and premium, if any, on such Note has become due and payable shall be paid to the Co-Issuers on their request or (if then held by the Co-Issuers) shall be discharged from such trust; and the Holder of such Note shall thereafter look only to the Co-Issuers for payment thereof, and all liability of the Trustee or such Paying

137

Agent with respect to such trust money, and all liability of the Co-Issuers as trustee thereof, shall thereupon cease.

Money so held in trust is subject to the Trustee’s rights under Section 7.07.

Section 9.03 [Reserved].

Section 9.04 Revocation and Effect of Consents.

(a) 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 of a Note and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting ▇▇▇▇▇▇’s Note, even if notation of the consent is not made on any Note. However, any such Holder of a Note or subsequent Holder of a Note 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. An amendment, supplement or waiver becomes effective in accordance with its terms and thereafter binds every Holder.

(b) The Co-Issuers may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to consent to any amendment, supplement or waiver. If a record date is fixed, then, notwithstanding the preceding paragraph, those Persons who were Holders at such record date (or their duly designated proxies), and only such Persons, shall be entitled to consent to such amendment, supplement, or waiver or to revoke any consent previously given, whether or not such Persons continue to be Holders after such record date.

Notwithstanding the foregoing and upon satisfaction of the requirements set forth in the last sentence of Section 9.01 hereof, no Opinion of Counsel shall be required for the Trustee to execute any amendment or supplement adding a new Guarantor under this Indenture. No amendment, supplement or waiver that may affect the rights, duties, liabilities or immunities of the Collateral Agent shall be effective without the prior written consent of the Collateral Agent.

(a) Subject to this Article 10, each of the Guarantors hereby, jointly and severally irrevocably and unconditionally guarantees (the “Note Guarantees”), to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee, the Collateral Custodian, the Collateral Agent and their respective successors and assigns, irrespective of the validity and enforceability of this Indenture, the Notes or the obligations of the Co-Issuers hereunder or thereunder, the due and punctual payment of the unpaid principal and interest on (including defaulted interest, if any, and interest accruing after the Stated Maturity of after the filing of any petition of bankruptcy, or the commencement of any insolvency, reorganization or like proceeding, relating to any Co-Issuer, whether or not a claim for post-filing or post-petition interest is allowed in such proceeding) each Note, whether at the Stated Maturity, upon redemption, upon required prepayment, upon acceleration, upon required repurchase at the option of the holder or otherwise according to the terms thereof and of this Indenture and all other obligations of the Co-Issuers to the Holders, the Trustee or the Collateral Custodian hereunder or thereunder shall be promptly paid in full or performed, all in accordance with the terms hereof and thereof. Failing payment when due of any amount so guaranteed or any performance so guaranteed for whatever reason, the Guarantors shall be jointly and severally obligated to pay the same immediately. Each Guarantor agrees that this is a guarantee of payment and not a guarantee of collection.

(b) The Guarantors hereby agree that their 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 of the Notes with respect to or any amendment of any provisions hereof or thereof, the recovery of any judgment against the Co-Issuers, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a Guarantor. Each Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Co-Issuers, any right to require a proceeding first against the Co-Issuers, protest, notice and all demands whatsoever and covenants that this Note Guarantee shall not be discharged except pursuant to Article 8 or Article 10 or by complete performance of the obligations contained in the Notes and this Indenture.

(c) If any Holder, the Trustee or the Collateral Custodian is required by any court or otherwise to return to the Co-Issuers, the Guarantors or any custodian, trustee, liquidator or other similar official acting in relation to either the Co-Issuers or the Guarantors, any amount paid either to the Trustee, the Collateral Custodian or such Holder, this Note Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect.

(d) Each Guarantor agrees that it shall not be entitled to any right of subrogation in relation to the Holders in respect of any obligations guaranteed hereby until payment in full of all obligations guaranteed hereby. Each Guarantor further agrees that, as between the Guarantors, on the one hand, and the Holders, the Trustee and the Collateral Agent, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article 6 hereof for the purposes of this Note Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (y) in the event of any declaration of acceleration of such obligations as provided in Article 6 hereof, such obligations (whether or not due and payable) shall forthwith become due and payable by the Guarantors for the purpose of this Note Guarantee. The Guarantors shall have the right to seek contribution from any non-paying Guarantor so long as the exercise of such right does not impair the rights of the Holders under the Note Guarantees.

144

(e) Each Note Guarantee shall remain in full force and effect and continue to be effective should any petition be filed by or against the Co-Issuers for liquidation or reorganization, should the Co-Issuers become insolvent or make an assignment for the benefit of creditors or should a receiver or trustee be appointed for all or any significant part of the Co-Issuers’ assets, and shall, to the fullest extent permitted by law, continue to be effective or be reinstated, as the case may be, if at any time payment and performance of the Notes are, pursuant to applicable law, rescinded or reduced in amount, or must otherwise be restored or returned by any obligee on the Notes or Note Guarantees, whether as a “voidable preference,” “fraudulent transfer” or otherwise, all as though such payment or performance had not been made. In the event that any payment, or any part thereof, is rescinded, reduced, restored or returned, the Notes shall, to the fullest extent permitted by law, be reinstated and deemed reduced only by such amount paid and not so rescinded, reduced, restored or returned.

Section 10.02 Limitation on Guarantor Liability.

Each Guarantor, and by its acceptance of Notes, each Holder, hereby confirms that it is the intention of all such parties that the Note Guarantee of such Guarantor not constitute a fraudulent transfer or conveyance for purposes of Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar federal or state law to the extent applicable to any Note Guarantee. To effectuate the foregoing intention, the Trustee, the Holders and the Guarantors hereby irrevocably agree that the obligations of each Guarantor shall be limited to the maximum amount as will, after giving effect to such maximum amount and all other contingent and fixed liabilities of such Guarantor that are relevant under such laws 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 this Article 10, result in the obligations of such Guarantor under its Note Guarantee not constituting a fraudulent conveyance or fraudulent transfer under applicable law or to comply with corporate benefit, financial assistance and other laws.

Section 10.03 Execution and Delivery.

(a) To evidence its Note Guarantee set forth in Section 10.01 hereof, each Guarantor hereby agrees that this Indenture shall be executed on behalf of such Guarantor by one of its Responsible Officers.

(b) Each Guarantor hereby agrees that its Note Guarantee set forth in Section 10.01 hereof shall remain in full force and effect notwithstanding the absence of the endorsement of any notation of such Note Guarantee on the Notes.

(c) If a Responsible Officer whose signature is on this Indenture no longer holds that office at the time the Trustee authenticates the Note, the Note Guarantee shall be valid nevertheless.

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

Section 10.04 Benefits Acknowledged.

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

Section 10.05 Release of Note Guarantees.

145

A Note Guarantee by a Guarantor shall be automatically and unconditionally released and discharged, and no further action by such Guarantor, the Co-Issuers or the Trustee is required for the release of such Guarantor’s Note Guarantee, upon the Co-Issuers’ exercising their Legal Defeasance option or Covenant Defeasance option in accordance with Article 8 hereof or the satisfaction and discharge of the Co-Issuers’ obligations under this Indenture in accordance with the terms of this Indenture or becomes an Excluded Subsidiary, so long as (i) no Event of Default shall have occurred and be continuing or shall result therefrom, (ii) the Co-Issuers shall have delivered a certificate of a Responsible Officer certifying that such conditions to the release of such Note Guarantee have been satisfied together with such information relating thereto as the Trustee may reasonably request and (iii) the Trustee shall execute and deliver, at the Co-Issuers’ expense, such documents as any Co-Issuer or Guarantor may reasonably request and prepare to evidence the release of the Note Guarantee of such Guarantor provided herein.

Section 12.18 Currency Indemnity.

Dollars are the sole currency (the “Required Currency”) of account and payment for all sums payable by the Co-Issuers or any Guarantor under or in connection with the Notes, this Indenture and the Note Guarantees, including damages. Any amount with respect to the Notes, this Indenture the Note Guarantees or the other Notes Documents received or recovered in a currency other than the Required Currency, whether as a result of, or the enforcement of, a judgment or order of a court of any jurisdiction, in the winding-up or dissolution of the Co-Issuers or any Guarantor or otherwise by any Holder or by the Trustee or Paying Agent or Collateral Agent, in respect of any sum expressed to be due to it from the Co-Issuers or any Guarantor will only constitute a discharge to the Co-Issuers or any Guarantor to the extent of the Required Currency amount which the recipient is able to purchase with the amount so received or recovered in that other currency on the date of that receipt or recovery (or, if it is not practicable to make that purchase on that date, on the first date on which it is practicable to do so).

If the Required Currency amount is less than the Required Currency amount expressed to be due to the recipient or the Trustee or Paying Agent or Collateral Custodian under the Notes, each of the Co-Issuers and each Guarantor will indemnify such recipient and/or the Trustee or Paying Agent or Collateral Custodian against any loss sustained by it as a result. In any event, the Co-Issuers and each Guarantor will indemnify the recipient against the cost of making any such purchase.

These indemnities constitute a separate and independent obligation from the Co-Issuers’ and each Guarantor’s other obligations, will give rise to a separate and independent cause of action, will apply irrespective of any waiver granted by any Holder of a Note or the Trustee or Paying Agent or Collateral Custodian (other than a waiver of the indemnities set out herein) and will continue in full force and effect despite any other judgment, order, claim or proof for a liquidated amount in respect of any sum due under any Note or to the Trustee or Collateral Custodian. For the purposes of determining the amount in a currency other than the Required Currency, such amount shall be determined using the Exchange Rate then in effect.

Section 12.19 Waiver of Immunity.

With respect to any proceeding, each party irrevocably waives, to the fullest extent permitted by applicable law, all immunity (whether on the basis of sovereignty or otherwise) from jurisdiction, service of process, attachment (both before and after judgment) and execution to which it might otherwise be entitled in any court of competent jurisdiction, and with respect to any judgment, each party waives any such immunity in any court of competent jurisdiction, and will not raise or claim or cause to be pleaded any such immunity at or in respect of any such proceeding or judgment, including any immunity pursuant to the United States Foreign Sovereign Immunities Act of 1976, as amended.

(b) to the extent such Collateral is comprised of property leased to a Co-Issuer or a Guarantor, upon termination or expiration of such lease, unless any Grantor owns the subject Collateral following such termination or expiration;

(c) if the release of such Lien is approved, authorized or ratified in writing by the Holders holding not less than the aggregate outstanding principal amount of the Notes required by Section 9.02;

(d) to the extent the property constituting such Collateral is owned by any Guarantor, upon the release of such Guarantor from its obligations under its Note Guarantee (in accordance with this Indenture);
