The aggregate principal amount of Notes which may be authenticated and issued under this Indenture is not limited; provided, however, that any Additional Notes issued under this Indenture are issued in accordance with Section 303 hereof, as part of the same series as the Notes.

The Notes shall be known and designated as the “5.750% Senior Notes due 2031” of the Issuers. The Stated Maturity of the Notes shall be October 1, 2031, and the Notes shall bear interest at the rate of 5.750% per annum from July 18, 2024, or from the most recent Interest Payment Date to which interest has been paid or duly provided for on the Notes.

The principal of (and premium, if any) and interest on the Notes shall be payable at the office or agency of the Issuers maintained for such purpose within the City and State of New York or, at the option of the Issuers, payment of interest may be made by check mailed to the Holders at their respective addresses set forth in the Note Register of Holders; provided that all payments of principal, premium, if any, and interest with respect to Notes represented by one or more Global Notes registered in the name of or held by the Depositary or its nominee will be made by wire transfer of immediately available funds to the accounts specified by the Holder or Holders thereof. Until otherwise designated by the Issuers, the Issuers’ office or agency in New York shall be the office of the trustee maintained for such purpose.

Holders shall have the right to require the Issuers to purchase their Notes, in whole or in part, in the event of a Change in Control pursuant to Section 1016.

-25-

SECTION 303. Execution, Authentication, Delivery and Dating.

The Notes shall be executed on behalf of each Issuer by any two Officers on behalf of Parent and one Officer of behalf of AIDAC. The signature of any Officer on the Notes may be manual or facsimile signatures (including any electronic signature) of the present or any future such authorized officer and may be imprinted or otherwise reproduced on the Notes.

Notes bearing the manual or facsimile signatures (including any electronic signature) of individuals who were at any time the proper officers of either Issuer shall bind such Issuer, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Notes or did not hold such offices at the date of such Notes.

At any time and from time to time after the execution and delivery of this Indenture, the Issuers may deliver Notes executed by the Issuers to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Notes, and the Trustee in accordance with such Company Order shall authenticate and deliver such Notes. Such Company Order shall identify the Notes to be authenticated, the date on which the original issue of the Notes is to be authenticated, the number of separate Note certificates, the principal amount of such Notes to be authenticated, the registered holder of each of the said Notes, and delivery instructions.

On the Issue Date, the Issuers shall deliver the Initial Notes in the aggregate principal amount of $500,000,000 executed by the Issuers to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Notes, directing the Trustee to authenticate the Notes and certifying that all conditions precedent to the issuance of Notes contained herein have been fully complied with, and the Trustee in accordance with such Company Order shall authenticate and deliver such Initial Notes. At any time and from time to time after the Issue Date, the Issuers may deliver Additional Notes executed by the Issuers to the Trustee for authentication, together with a Company Order for the authentication and delivery of such Additional Notes, directing the Trustee to authenticate the Additional Notes and certifying that the issuance of such Additional Notes is in compliance with Article Ten hereof and that all other conditions precedent to the issuance of Notes contained herein have been fully complied with, and the Trustee in accordance with such Company Order shall authenticate and deliver such Additional Notes; provided, however, that, notwithstanding anything to the contrary, no Opinion of Counsel will be required in connection with the authentication of the Initial Notes. In each case, the Trustee shall receive an Officers’ Certificate and an Opinion of Counsel of the Issuers that it may reasonably require in connection with such authentication of Notes. Such order shall specify the amount of Notes to be authenticated and the date on which the original issue of Notes is to be authenticated.

Each Note shall be dated the date of its authentication.

No Note shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Note a certificate of authentication substantially in the form provided for herein duly executed by the Trustee by manual signature of an authorized officer, and such certificate upon any Note shall be conclusive evidence, and the only evidence, that such Note has been duly authenticated and delivered hereunder and is entitled to the benefits of this Indenture.

In case either Issuer, pursuant to Article Eight, shall be amalgamated, consolidated or merged with or into any other Person or shall convey, transfer, lease or otherwise dispose of its properties and assets substantially as an entirety to any Person, and the successor Person resulting from such amalgamation or consolidation, or surviving such merger, or into which such Issuer shall have been merged, or the Person which shall have received a conveyance, transfer, lease or other disposition as

-26-

aforesaid, shall have executed a supplemental indenture hereto with the Trustee pursuant to Article Nine, any of the Notes authenticated or delivered prior to such consolidation, merger, conveyance, transfer, lease or other disposition may, from time to time, at the request of the successor Person, be exchanged for other Notes executed in the name of the successor Person with such changes in phraseology and form as may be appropriate, but otherwise in substance of like tenor as the Notes surrendered for such exchange and of like principal amount; and the Trustee, upon Company Request of the successor Person, shall authenticate and deliver Notes as specified in such request for the purpose of such exchange. If Notes shall at any time be authenticated and delivered in any new name of a successor Person pursuant to this Section in exchange or substitution for or upon registration of transfer of any Notes, such successor Person, at the option of the Holders but without expense to them, shall provide for the exchange of all Notes at the time Outstanding for Notes authenticated and delivered in such new name.

SECTION 304. Temporary Notes.

In the event Definitive Notes are to be issued pursuant to the terms of this Indenture, pending the preparation of Definitive Notes, the Issuers may execute, and upon Company Order the Trustee shall authenticate and deliver, temporary Notes which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the Definitive Notes in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Notes may determine, as conclusively evidenced by their execution of such Notes.

If temporary Notes are issued, the Issuers will cause Definitive Notes to be prepared without unreasonable delay. After the preparation of Definitive Notes, the temporary Notes shall be exchangeable for Definitive Notes upon surrender of the temporary Notes at the office or agency of the Issuers designated for such purpose pursuant to Section 1002, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Notes, the Issuers shall execute and the Trustee shall authenticate and deliver in exchange therefor a like principal amount of Definitive Notes of authorized denominations. Until so exchanged, the temporary Notes shall in all respects be entitled to the same benefits under this Indenture as Definitive Notes.

SECTION 305. Registration, Paying Agent, Registration of Transfer and Exchange.

The Issuers shall cause to be kept at the Corporate Trust Office of the Trustee a register (the register maintained in such office and in any other office or agency designated pursuant to Section 1002 being herein sometimes referred to as the “Note Register”) in which, subject to such reasonable regulations as it may prescribe, the Issuers shall provide for the registration of Notes and of transfers of Notes. The Note Register shall be in written form or any other form capable of being converted into written form within a reasonable time. At all reasonable times, the Note Register shall be open to inspection by the Trustee. The Trustee is hereby initially appointed as note registrar (the “Note Registrar”) for the purpose of registering Notes and transfers of Notes as herein provided and as Paying Agent. The Issuers may appoint one or more co-registrars and one or more additional paying agents. The Issuers may change any Paying Agent or Registrar without prior notice to any Holder; provided, that the Issuers shall maintain one or more Paying Agents in the Borough of Manhattan, City of New York. The Issuers shall notify the Trustee in writing of the name and address of any Agent not party to this Indenture. If the Issuers fail to appoint or maintain another entity as Registrar or Paying Agent, the Trustee shall act as such. The Issuers may act as Paying Agent or Registrar.

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

-27-

Upon surrender for registration of transfer of any Note at the office or agency of the Issuers designated pursuant to Section 1002, the Issuers shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Notes of any authorized denomination or denominations of a like aggregate principal amount.

At the option of the Holder, Notes may be exchanged for other Notes of any authorized denomination and of a like aggregate principal amount, upon surrender of the Notes to be exchanged at such office or agency. Whenever any Notes are so surrendered for exchange, the Issuers shall execute, and the Trustee shall authenticate and deliver, the Notes which the Holder making the exchange is entitled to receive.

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

Every Note presented or surrendered for registration of transfer or for exchange shall (if so required by the Issuers or the Note Registrar) be duly endorsed, or be accompanied by written instruments of transfer, in form satisfactory to the Issuers and the Note Registrar, duly executed by the Holder thereof or his attorney duly authorized in writing.

No service charge shall be made for any registration of transfer or exchange or redemption of Notes, but the Issuers may require payment of a sum sufficient to cover any taxes, fees or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Notes, other than exchanges pursuant to Sections 303, 304, 906, 1016 or 1109 not involving any transfer.

Neither the Registrar nor the Issuers shall be required to register the transfer of or exchange any Note selected for redemption in whole or in part, except the unredeemed portion of any Note being redeemed in part.

SECTION 306. Mutilated, Destroyed, Lost and Stolen Notes.

If (i) any mutilated Note is surrendered to the Trustee, or (ii) the Issuers and the Trustee receive evidence to their satisfaction of the destruction, loss or theft of any Note, and there is delivered to the Issuers and the Trustee such security or indemnity as may be required by them to protect the Trustee, any Agent and the Issuers from any loss, then, in the absence of notice to the Issuers or the Trustee that such Note has been acquired by a bona fide purchaser, the Issuers shall execute and upon Company Order the Trustee shall authenticate and deliver, in exchange for any such mutilated Note or in lieu of any such destroyed, lost or stolen Note, a new Note of like tenor and principal amount, 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 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 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.

-28-

Every new Note issued pursuant to this Section in lieu of any mutilated, destroyed, lost or stolen Note shall constitute an original additional contractual obligation of the Issuers and shall be entitled to all benefits of this Indenture equally and proportionately with any and 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 307. Payment of Interest; Interest Rights Preserved.

Interest on any Note which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name such Note (or one or more Predecessor Notes) is registered at the close of business on the Regular Record Date for such interest at the office or agency of the Issuers maintained for such purpose pursuant to Section 1002; provided, however, that, subject to Section 301 hereof, each installment of interest may at the Issuers’ option be paid by (i) mailing a check for such interest, payable to or upon the written order of the Person entitled thereto pursuant to Section 308, to the address of such Person as it appears in the Note Register or (ii) transfer to an account located in the United States maintained by the payee.

Any interest on any Note which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date shall forthwith cease to be payable to the Holder on the Regular Record Date by virtue of having been paid to such Holder, and such defaulted interest and (to the extent lawful) interest on such defaulted interest at the rate borne by the Notes (such defaulted interest and interest thereon herein collectively called “Defaulted Interest”) may be paid by the Issuers, at their election in each case, as provided in clause (1) or (2) below:

(1) The Issuers may elect to make payment of any Defaulted Interest on the Notes to the Persons in whose names such Notes (or their respective Predecessor Notes) are registered at the close of business on a Special Record Date for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Issuers shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Note and the date of the proposed payment, and at the same time the Issuers shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Issuers of such Special Record Date, and in the name and at the expense of the Issuers, shall cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be given in the manner provided for in Section 106, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so given, such Defaulted Interest shall be paid to the Persons in whose names the Notes (or their respective Predecessor Notes) are registered at the close of business on such Special Record Date and shall no longer be payable pursuant to the following clause (2).

-29-

(2) The Issuers may make payment of any Defaulted Interest in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Notes may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Issuers to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee.

Subject to the foregoing provisions of this Section, each Note delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Note shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Note.

SECTION 308. Persons Deemed Owners.

Prior to the due presentment of a Note for registration of transfer, the Issuers, the Trustee and any agent of the Issuers or the Trustee may treat the Person in whose name such Note is registered as the owner of such Note for the purpose of receiving payment of principal of (and premium, if any) and (subject to Sections 305 and 307) interest on such Note and for all other purposes whatsoever, whether or not such Note be overdue, and none of the Issuers, the Trustee or any agent of the Issuers or the Trustee shall be affected by notice to the contrary.

SECTION 309. Cancellation.

All Notes surrendered for payment, redemption, registration of transfer or exchange shall, if surrendered to any Person other than the Trustee, be delivered to the Trustee and shall be promptly cancelled by it. The Issuers may at any time deliver to the Trustee for cancellation any Notes previously authenticated and delivered hereunder. All Notes so delivered shall be promptly cancelled by the Trustee. If the Issuers shall so acquire any of the Notes, however, such acquisition shall not operate as a redemption or satisfaction of the indebtedness represented by such Notes unless and until the same are surrendered to the Trustee for cancellation. No Notes shall be authenticated in lieu of or in exchange for any Notes cancelled as provided in this Section, except as expressly permitted by this Indenture. All cancelled Notes held by the Trustee shall be disposed of by the Trustee in accordance with its customary procedures. Evidence of the disposition of all cancelled Notes shall upon the written request of the Issuers be delivered to the Issuers.

SECTION 310. Computation of Interest.

Interest on the Notes shall be computed on the basis of a 360-day year of twelve 30-day months.

(2) the holders thereof have rescinded or waived the acceleration, notice or action (as the case may be) giving rise to such Event of Default, or

(3) if the default that is the basis for such Event of Default has been cured.

SECTION 503. Collection of Indebtedness and Suits for Enforcement by Trustee.

The Issuers covenant, jointly and severally, that if an Event of Default specified in Section 501(1) or 501(2) hereof occurs and is continuing with respect to the Notes, the Issuers will, upon demand of the Trustee, pay to the Trustee for the benefit of the Holders of such Notes, the whole amount then due and payable on such Notes for principal (and premium, if any) and interest, and interest on any overdue principal (and premium, if any) and, to the extent that payment of such interest shall be legally enforceable, upon any overdue installment of interest, at the rate borne by such Notes, and, in addition thereto, 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.

If the Issuers fail to pay such amounts forthwith upon such demand, the Trustee, in its own name as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Issuers or any other obligor upon the Notes and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Issuers or any other obligor upon such Notes, wherever situated.

If an Event of Default occurs and is continuing with respect to the Notes, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders under this Indenture and the Note Guarantees by such appropriate judicial proceedings as the Trustee shall deem necessary to protect and enforce any such rights whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy.

In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Issuers or any other obligor, upon the Notes or the property of the Issuers or of such other obligor or their creditors, the Trustee (irrespective of whether the principal of the Notes shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Issuers for the payment of overdue principal, premium, if any, or interest) shall be entitled and empowered, by intervention in such proceeding or otherwise,

-45-

(i) to file and prove a claim for the whole amount of principal (and premium, if any) and interest owing and unpaid in respect of the Notes and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel) and of the Holders allowed in such judicial proceeding, and

(ii) to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay the Trustee any amount due it for the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel, and any other amounts due the Trustee hereunder.

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 thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

SECTION 511. 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.

(2) the Trustee shall cease to be eligible under Section 608 and shall fail to resign after written request therefor by the Issuers or by any Holder who has been a bona fide Holder of a Note for at least six months, or

(3) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent or a receiver of the Trustee or of its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation,

then, in any such case, (i) the Issuers, by a Board Resolution, may remove the Trustee, or (ii) any Holder who has been a bona fide Holder of a Note for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee and the appointment of a successor Trustee.

SECTION 610. Acceptance of Appointment by Successor.

(a) Every successor Trustee appointed hereunder shall execute, acknowledge and deliver to the Issuers and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on request of the Issuers or the successor Trustee, such retiring Trustee shall, upon payment of its charges, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder. Upon request of any such successor Trustee, the Issuers shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts. The retiring Trustee shall have no responsibility or liability for the action or inaction of any successor Trustee.

(b) Upon request of any such successor Trustee, the Issuers shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all rights, powers and trusts referred to in paragraph (a) of this Section.

In case any Notes shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Notes so authenticated with the same effect as if such successor Trustee had itself authenticated such Notes. In case at that time any of the Notes shall not have been authenticated, any successor Trustee may authenticate such Notes either in the name of any predecessor hereunder or in the name of the successor Trustee. In all such cases such certificates shall have the full force and effect which this Indenture provides for the certificate of authentication of the Trustee shall have; provided, however, that the right to adopt the certificate of authentication of any predecessor Trustee or to authenticate Notes in the name of any predecessor Trustee shall apply only to its successor or successors by merger, conversion or consolidation.

SECTION 612. Appointment of Authenticating Agent.

At any time when any of the Notes remain Outstanding, the Trustee may appoint an Authenticating Agent or Agents with respect to the Notes which shall be authorized to act on behalf of the Trustee to authenticate Notes and the Trustee shall give written notice of such appointment to all Holders of Notes with respect to which such Authenticating Agent will serve, in the manner provided for in Section 106. Notes so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Any such appointment shall be evidenced by an instrument in writing signed by a Responsible Officer of the Trustee, and a copy of such instrument shall be promptly furnished to the Issuers. Wherever reference is made in this Indenture to the authentication and delivery of Notes by the Trustee or the Trustee’s certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the Issuers and shall at all times be a corporation organized and doing business under the laws of the United States of America, any state thereof or the District of Columbia, authorized under such laws to act as Authenticating Agent, having a combined capital and surplus of not less than $50,000,000 and subject to supervision or examination by Federal or state authority. If such corporation publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect specified in this Section.

Any corporation into which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to all or substantially all the corporate agency or corporate trust business of an Authenticating Agent, shall continue to be an Authenticating Agent, provided such corporation shall be otherwise eligible under this Section, without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent.

-55-

An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee and to the Issuers. The Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Issuers. Upon receiving such a notice of resignation or upon such a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Issuers and shall give written notice of such appointment to all Holders of Notes, in the manner provided for in Section 106. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section.

The Issuers agree to pay to each Authenticating Agent from time to time such compensation for its services under this Section as shall be agreed in writing between the Issuers and such Authenticating Agent.

If an appointment is made pursuant to this Section, the Notes may have endorsed thereon, in addition to the Trustee’s certificate of authentication, an alternate certificate of authentication in the following form:

This is one of the Notes designated therein referred to in the within-mentioned Indenture.

SECTION 613. Force Majeure.

In no event shall the Trustee be responsible or liable for any failure or delay in the performance of its obligations hereunder arising out of or caused by, directly or indirectly, forces beyond its control, including, without limitation, (i) any act or provision of any present or future law or regulation or governmental authority, (ii) any act of God, (iii) natural disaster, (iv) war, (v) terrorism, (vi) civil unrest, (vii) accidents, (viii) labor dispute, (ix) disease, (x) epidemic or pandemic, (xi) quarantine, (xii) national emergency, (xiii) loss or malfunction of utility or computer software or hardware, (xiv) communications system failure, (xv) malware or ransomware or hacking, cyber-attacks, or other use or infiltration of the Trustee’s technological infrastructure exceeding authorized access; (xvi) unavailability of the Federal Reserve Bank wire or telex system or other wire or other funds transfer systems, or (xvii) unavailability of any securities clearing system, it being understood that the Trustee shall use reasonable efforts which are consistent with accepted practices in the banking industry to resume performance as soon as practicable under the circumstances.

SECTION 1004. Corporate Existence.

SECTION 1007. Insurance.

(a) Parent will at all times keep all of its and its Subsidiaries’ properties which are of an insurable nature insured with insurers, believed by Parent to be responsible (including, to the extent consistent with past practice, self-insurance), against loss or damage to the extent that property of similar character is usually so insured by corporations similarly situated and owning like properties.

(b) In connection with the covenants set forth in this Section 1007, it is understood and agreed that:

(ii) the designation of any form, type or amount of insurance coverage by the Trustee under this Section 1007 shall in no event be deemed a representation, warranty or advice by the Trustee that such insurance is adequate for the purposes of the business of Parent or the protection of its properties.

-64-

there is no Default or Event of Default which has occurred and is continuing or, if such signers do know of such Default or Event of Default, the certificate shall describe its status, with particularity and that, to the best of his or her knowledge, no event has occurred and remains by reason of which payments on the account of the principal of or interest, if any, on the Notes is prohibited or if such event has occurred, a description of the event and what action each is taking or proposes to take with respect thereto. The Officers’ Certificate shall also notify the Trustee should Parent elect to change the manner in which it fixes its fiscal year-end. For purposes of this Section, such compliance shall be determined without regard to any period of grace or requirement of notice under this Indenture.

(b) (i) When any Default or Event of Default has occurred and is continuing under this Indenture, or (ii) if the trustee for or the holder of any other evidence of Indebtedness of Parent or any Subsidiary gives any notice or takes any other action with respect to a claimed default (other than with respect to Indebtedness in the principal amount of less than $50,000,000), the Issuers shall deliver to the Trustee by registered or certified mail or overnight delivery or PDF or other electronic transmission an Officers’ Certificate specifying such event, notice or other action within ten Business Days of any Officer becoming aware of the foregoing.

Thereafter, such Subsidiary shall be a Guarantor for all purposes of this Indenture until such Note Guarantee is released in accordance with the provisions of this Indenture. In the event of a sale or other transfer or disposition of all of the Capital Stock in any Guarantor to any Person that is not an Affiliate of Parent in compliance with the terms of this Indenture, or in the event all or substantially all the assets or Capital Stock of a Guarantor are sold or otherwise transferred, by way of merger, consolidation or otherwise, to a Person that is not an Affiliate of Parent in compliance with the terms of this Indenture, then, without any further action on the part of the Trustee or any Holder, such Guarantor (or the Person concurrently acquiring such assets of such Guarantor) shall be deemed automatically and unconditionally cancelled, released and discharged of any obligations under its Note Guarantee, as evidenced by a supplemental indenture, written instrument or confirmation executed by the Trustee, upon request; provided, however that if evidence of such cancellation, discharge or release is requested to be executed by the Trustee, an Officers’ Certificate and an Opinion of Counsel complying with Section 1301 of this Indenture. Any Note Guarantee may include provisions that a Guarantor of such Note Guarantee shall be deemed automatically and unconditionally cancelled, released and discharged of any obligations under its Note Guarantee under certain circumstances, as evidenced by a supplemental indenture, written instrument or confirmation executed by the Trustee, upon request.

Each Note Guarantee by a Subsidiary of Parent will be limited to an amount not to exceed the maximum amount that can be guaranteed by that Subsidiary without rendering the Note Guarantee, as it relates to such Subsidiary, voidable under applicable law relating to fraudulent conveyance or fraudulent transfer or similar laws affecting the rights of creditors generally.

SECTION 1021. Additional Amounts.

If the Issuers (or a Guarantor, if any) or other applicable withholding agent is required by law to deduct or withhold taxes imposed by Bermuda, Ireland or another Relevant Tax Jurisdiction on payments to Holders, it will pay to any Holder so entitled all additional amounts that may be necessary so that every Net Payment of interest, principal, premium or other amount received by the beneficial owner on that Note or the Note Guarantee will not be less than the amount provided for in that Note or the Note Guarantee.

-69-

(a) The Issuers (and Guarantors, if any) will also indemnify and reimburse Holders for:

(1) Taxes (including any interest, penalties and related expenses) imposed on the Holders (or if a Holder is not the beneficial owner, the beneficial owner) by a Relevant Tax Jurisdiction if and to the same extent that a Holder would have been entitled to receive additional amounts if the Issuers (or a Guarantor) or other applicable withholding agent had been required to deduct or withhold those taxes from payments on the Notes or the Note Guarantees; and

(2) Stamp, court, issue, registration, documentary or similar taxes or charges (including any interest, penalties and related expenses) imposed by a Relevant Tax Jurisdiction in connection with the execution, delivery, enforcement or registration of the Notes or the Note Guarantees or other related documents and obligations.

(b) The Issuers (or a Guarantor) will not pay additional amounts to any Holder for or on account of any of the following:

(1) Any tax, assessment or other governmental charge imposed solely because at any time there is or was a connection between such Holder (or between a fiduciary, settlor, beneficiary, member or shareholder of or possessor of power over the relevant Holder if the Holder is an estate, nominee, trust, partnership, limited liability company, or corporation) and the Relevant Tax Jurisdiction imposing the tax (other than any connection arising as a result of receipt of a payment or the acquisition, ownership, disposition or holding of, or enforcement of rights under, a Note or the Note Guarantees);

(2) Any estate, inheritance, gift or any similar tax, assessment or other governmental charge;

(3) Any tax, assessment or other governmental charge imposed solely because such Holder (or if such Holder is not the beneficial owner, the beneficial owner) fails to comply with any certification, identification or other reporting requirement concerning the nationality, residence, identity or connection with the taxing jurisdiction of such Holder or any beneficial owner of the Note or the Note Guarantees, if compliance is required by law or by an applicable income tax treaty to which the jurisdiction imposing the tax is a party, as a precondition to an exemption from the tax, assessment or other governmental charge for which such Holder is eligible and the Issuers (or a Guarantor) have given the Holders at least 60 days’ written notice that Holders will be required to provide such information and identification; and

(4) Any tax, assessment or other governmental charge with respect to a Note or a Note Guarantee presented for payment more than 30 days after the date on which payment became due and payable or the date on which payment thereof is duly provided for and notice thereof given to Holders, whichever occurs later, except to the extent that such Holder of the Note would have been entitled to additional amounts on presenting the Note for payment on any date during the 30-day period.

ARTICLE ELEVEN

REDEMPTION OF NOTES

SECTION 1101. Right of Redemption.

(a) Prior to August 1, 2031 (two months prior to the Stated Maturity) (the “Par Call Date”), the Issuers may redeem the Notes at their option, in whole or in part, at any time and from time to time, at a Redemption Price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of: (1) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming the Notes matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 25 basis points less (b) interest accrued to, but not including, the date of redemption (the “Applicable Premium”), and (2) 100% of the principal amount of the Notes to be redeemed, plus, in either case, accrued and unpaid interest thereon to, but excluding, the Redemption Date.

(b) On or after the Par Call Date, the Issuers may redeem the Notes, in whole or in part, at any time and from time to time, at a Redemption Price equal to 100% of the aggregate principal amount of the Notes being redeemed plus accrued and unpaid interest thereon, if any, to, but not including, the Redemption Date.

(c) The Issuers’ actions and determinations in determining the Redemption Price shall be conclusive and binding for all purposes, absent manifest error.

(d) Notice of any redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with DTC’s procedures) at least 10 days but not more than 60 days before the Redemption Date to each Holder to be redeemed.

(e) In the case of a partial redemption, selection of the Notes for redemption will be made pro rata, by lot or such similar method in accordance with the procedures of DTC. No Notes of a principal amount of $150,000 or less will be redeemed in part. If any Note is to be redeemed in part only, the notice of redemption that relates to the Note will state the portion of the principal amount of the Note to be redeemed. A new Note in a principal amount equal to the unredeemed portion of the Note will be issued in the name of the Holder upon surrender for cancellation of the original Note. For so long as the Notes are held by DTC (or another depository), the redemption of the Notes shall be done in accordance with the policies and procedures of DTC.

(f) Unless the Issuers default in payment of the Redemption Price, on and after the Redemption Date interest will cease to accrue on the Notes or portions thereof called for redemption.

(g) Any notice of redemption may, at the Issuers’ option and discretion, be subject to one or more conditions precedent, including, but not limited to, completion of any debt or equity financing, acquisition or other corporate transaction. In addition, if such redemption is subject to satisfaction of one or more conditions precedent, such notice shall state that, in the Issuers’ sole discretion, the redemption date may be delayed until such time as any or all such conditions shall be satisfied, or such redemption 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 so delayed. In addition, the Issuers may provide in such notice that payment of the redemption price and performance of the Issuers’ obligations with respect to such redemption may be performed by another Person (it being understood that any such provision for payment by another Person will not relieve the Issuers and the Guarantors from their obligations with respect to such redemption).

-71-

(h) The Issuers shall provide at least two Business Days’ prior written notice to the Trustee prior to the Redemption Date (or such lesser period as the Trustee may agree to) if any such redemption is being rescinded or delayed, and upon receipt, the Trustee shall promptly provide such notice to each Holder of the Notes in the manner provided for in Section 106.

(i) In addition to the Issuers’ rights to redeem the Notes as set forth in subclauses (a) through (h) above the Issuers may at any time purchase Notes in open market transactions, tender offers, privately negotiated transactions or otherwise.

(j) Notwithstanding anything to the contrary herein (including in Section 1105 hereof), the provisions of this Section 1101 will apply to any redemption effected pursuant to this Section 1101.

SECTION 1102. Redemption for Taxation Reasons.

The Issuers will be entitled, at their option, to redeem the Notes in whole if at any time it becomes obligated to pay additional amounts on the Notes on the next Interest Payment Date with respect to the Notes, but only if the obligation results from a change in, or an amendment to, the laws or treaties (including any regulations or official rulings promulgated thereunder) of a Relevant Tax Jurisdiction (or a political subdivision or taxing authority thereof or therein), or from a change in any official position regarding the interpretation, administration or application of those laws, treaties, regulations or official rulings (including a change resulting from a holding, judgment or order by a court of competent jurisdiction), that becomes effective and is announced after the Issue Date (or, if the applicable Relevant Tax Jurisdiction became a Relevant Tax Jurisdiction on a date after the Issue Date, such later date) and provided the Issuers cannot avoid the obligation after taking reasonable measures to do so. If the Issuers redeem the Notes in these circumstances, it will do so at a Redemption Price equal to 100% of the principal amount of the Notes redeemed, plus accrued and unpaid interest, if any, and any other amounts due to, but excluding, the Redemption Date.

If the Issuers become entitled to redeem the Notes in these circumstances, it may do so at any time on a redemption date of its choice. However, the Issuers must give the Holders of Notes being redeemed notice of the redemption not less than 10 days or more than 60 days before the redemption date and not more than 90 days before the next date on which they would be obligated to pay additional amounts. In addition, the Issuers’ obligation to pay additional amounts must remain in effect when they give the notice of redemption. Notice of the Issuers’ intent to redeem the Notes shall not be effective until such time they deliver to the Trustee an Officers’ Certificate stating that the obligation to pay additional amounts cannot be avoided by taking reasonable measures and an opinion of independent legal counsel or an independent auditor stating that the Issuers are obligated to pay additional amounts because of an amendment to or change in law, treaties or position as described in the preceding paragraph. In addition to the Issuers’ rights to redeem Notes as set forth above, the Issuers may at any time and from time to time purchase Notes in open-market transactions, tender offers, privately negotiated purchases or otherwise.

(4) no Default or Event of Default with respect to the Outstanding Notes (other than that resulting from borrowing funds to be applied to make such deposit or the granting of Liens in connection therewith) shall have occurred and be continuing on the date of such deposit;

(5) such Legal Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under any other material agreement or instrument (other than this Indenture) to which, the Issuers are a party or by which one of the Issuers is bound (other than that resulting from borrowing funds to be applied to make such deposit and the granting of Liens in connection therewith); and

(6) the Issuers shall have delivered to the Trustee an Officers’ Certificate and an Opinion of Counsel in the United States (which Opinion of Counsel may be subject to customary assumptions and exclusions), 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.

The Issuers shall pay and indemnify the Trustee against any tax, fee or other charge imposed on or assessed against the Government Securities deposited pursuant to Section 1204 or the principal and interest received in respect thereof other than any such tax, fee or other charge which by law is for the account of the Holders of the Outstanding Notes.

Anything in this Article Twelve to the contrary notwithstanding, the Trustee shall deliver or pay to the Issuers from time to time upon Company Request any money or Government Securities held by it as provided in Section 1204 which, in the opinion of a nationally recognized firm of independent public accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect an equivalent Legal Defeasance or Covenant Defeasance, as applicable, in accordance with this Article.

-77-

SECTION 1206. Reinstatement.

If the Trustee or any Paying Agent is unable to apply any money or Government Securities in accordance with Section 1205 by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Issuers’ obligations under this Indenture and the Outstanding Notes shall be revived and reinstated as though no deposit had occurred pursuant to Section 1202 or 1303, as the case may be, until such time as the Trustee or Paying Agent is permitted to apply all such money or Government Securities in accordance with Section 1205; provided, however, that if the Issuers make any payment of principal of (or premium, if any) or interest on any Note following the reinstatement of its obligations, the Issuers shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money or Government Securities held by the Trustee or Paying Agent.

The Notes are subject to all such terms, and Holders are referred to the Indenture for a statement of all such terms. To the extent permitted by applicable law, in the event of any inconsistency between the terms of this Note and the terms of the Indenture, the terms of the Indenture shall control.

The Notes are senior unsecured obligations of the Issuers. The Indenture does not limit the aggregate principal amount of the Notes.

Optional Redemption. Prior to August 1, 2031 (two months prior to the maturity date of the Notes) (the “Par Call Date”), the Issuers may redeem the Notes at their option, in whole or in part, at any time and from time to time, at a redemption price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of: (1) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming the Notes matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 25 basis points less (b) interest accrued to, but not including, the date of redemption (the “Applicable Premium”), and (2) 100% of the principal amount of the Notes to be redeemed, plus, in either case, accrued and unpaid interest thereon to, but excluding, the Redemption Date.

On or after the Par Call Date, the Issuers may redeem the Notes, in whole or in part, at any time and from time to time, at a redemption price equal to 100% of the aggregate principal amount of the Notes being redeemed plus accrued and unpaid interest thereon, if any, to, but not including, the Redemption Date.

The Issuers will be entitled, at its option, to redeem the Notes in whole if at any time it becomes obligated to pay additional amounts on the Notes on the next Interest Payment Date with respect to the Notes, but only if their obligation results from a change in, or an amendment to, the laws or treaties (including any regulations or official rulings promulgated thereunder) of a Relevant Tax Jurisdiction (or a political subdivision or taxing authority thereof or therein), or from a change in any official position regarding the interpretation, administration or application of those laws, treaties, regulations or official rulings (including a change resulting from a holding, judgment or order by a court of competent jurisdiction), that becomes effective and is announced after the Issue Date (or, if the applicable Relevant Tax Jurisdiction became a Relevant Tax Jurisdiction on a date after the Issue Date, such later date) and provided the Issuers cannot avoid the obligation after taking reasonable measures to do so. If the Issuers redeem the Notes in these circumstances, it will do so at a Redemption Price equal to 100% of the principal amount of the Notes redeemed, plus accrued and unpaid interest, if any, and any other amounts due to, but excluding, the Redemption Date.

A-1-5

If the Issuers become entitled to redeem the Notes in these circumstances, they may do so at any time on a redemption date of its choice. However, the Issuers must give the Holders being redeemed notice of the redemption not less than 10 days or more than 60 days before the redemption date and not more than 90 days before the next date on which they would be obligated to pay additional amounts. In addition, the Issuers’ obligation to pay additional amounts must remain in effect when they give the notice of redemption. Notice of the Issuers’ intent to redeem the Notes shall not be effective until such time as they deliver to the Trustee both a certificate signed by two Officers on behalf of Parent and one Officers on behalf of AIDAC stating that the obligation to pay additional amounts cannot be avoided by taking reasonable measures and an opinion of independent legal counsel or an independent auditor stating that the Issuers are obligated to pay additional amounts because of an amendment to or change in law, treaties or position as described in the preceding paragraph.

In addition to the Issuers’ rights to redeem Notes as set forth above, the Issuers may at any time purchase Notes in open-market transactions, tender offers, privately negotiated purchases or otherwise.

Upon the occurrence of a Change in Control Triggering Event, the Holders will have the right to require that the Issuers purchase such Holder’s outstanding Notes, in whole or in part, at a purchase price of 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to, but excluding, the date of purchase.

The Notes are in registered form without coupons, in minimum denominations of $150,000 and integral multiples of $1,000 in excess thereof. A Holder may register the transfer or exchange of Notes in accordance with the Indenture. The Note Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay any taxes and fees required by law or permitted by the Indenture. The Note Registrar need not register the transfer or exchange of any Notes (i) during a period beginning at the opening of business 15 days before the mailing of a notice of redemption of Notes for redemption under Section 1105 of the Indenture and ending at the close of business on the day of such mailing, (ii) selected for redemption (except the unredeemed portion of any Note being redeemed in part) and (iii) between a Record Date and the next succeeding Interest Payment Date.

A registered Holder may be treated as the owner of a Note for all purposes.

If money for the payment of principal (premium, if any) or interest remains unclaimed for two years, the Trustee and the Paying Agent will pay the money back to the Issuers at their written request. After that, Holders entitled to the money must look to the Issuers for payment, unless an abandoned property law designates another Person, and all liability of the Trustee and such Paying Agent with respect to such money shall cease.

A-1-6

Subject to certain conditions, the Issuers at any time shall be entitled to terminate some or all of their obligations under the Notes and the Indenture if the Issuers deposit with the Trustee money or Government Securities for the payment of principal and interest on the Notes to redemption or maturity, as the case may be.

Subject to certain exceptions, the Indenture or the Notes may be amended or supplemented with the consent of the Holders of at least a majority in aggregate principal amount of the Outstanding Notes, and any existing Default or compliance with any provision may be waived with the consent of the Holders of a majority in aggregate principal amount of the Outstanding Notes. Without notice to or the consent of any Holder, the parties thereto may amend or supplement the Indenture or the Notes to, among other things, cure any ambiguity, defect or inconsistency and make any change that does not adversely affect the rights of any Holder.

The Indenture contains certain covenants, including, without limitation, covenants with respect to the following matters: (i) Liens; (ii) Purchase of Notes upon a Change in Control; (iii) Note Guarantees; and (iv) Amalgamation, Merger, Consolidation or Sale of all or Substantially all Assets.

When a successor Person or other entity assumes all the obligations of its predecessor under the Notes and the Indenture, the predecessor Person will be released from those obligations.

If an Event of Default, as defined in the Indenture, occurs and is continuing, the Trustee or the Holders of at least 30% in principal amount of the Outstanding Notes may declare all the Notes to be immediately due and payable. If a bankruptcy or insolvency default with respect to Parent or any of its Significant Subsidiaries occurs and is continuing, the Notes automatically become immediately due and payable. Holders may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee may require indemnity reasonably satisfactory to it before it enforces the Indenture or the Notes. Subject to certain limitations, Holders of at least a majority in aggregate principal amount of the Outstanding Notes may direct the Trustee in its exercise of any trust or power.

If the Notes are guaranteed, the Issuers’ obligations under the Notes are fully, irrevocably and unconditionally guaranteed on a senior basis, to the extent set forth in the Indenture, by each of the Guarantors.

The Trustee under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may make loans to, accept deposits from, perform services for, and otherwise deal with, the Issuers and their respective Affiliates as if it were not the Trustee.
