(1) the termination of the period described above for the holder or beneficial owner to apply for a license, qualification or finding of suitability; or

(2) the receipt of the notice from the Gaming Authority that the holder or beneficial owner shall not be licensed, qualified or found suitable by the Gaming Authority; or

5

circumstances. Any and all waivers, consents or approvals made or given, or deemed given, by the holders of the Senior Indebtedness (or any agent or adviser acting on their behalf) under the Senior Loan Facilities shall apply to the Notes with the same effect as if the waiver had been given by the holders of the Notes.

8.2. | Aggregate Principal Amount of Senior Indebtedness

Notwithstanding Section 8.1, the Company shall not amend, supplement, refinance or replace the Senior Loan Facilities such that the principal amount of funded Senior Indebtedness outstanding at any time exceeds $1,200,000,000 (or if the Company incurs Financial Indebtedness (as defined in the Common Terms Agreement) permitted under paragraph 2(f) of Schedule 5, Part B of the Common Terms Agreement, $1,200,000,000 plus an amount being 150% of the aggregate amount of such Financial Indebtedness incurred by the Company).

To this end, each holder of Notes shall cooperate with the Company in its incurrence of Senior Indebtedness by taking all actions requested by the Company to facilitate such incurrence, including, without limitation, entering into intercreditor agreements that, taken as a whole, are not less favorable to the holders of Notes than the terms of the Deed of Appointment and Priority.

10. | EVENTS OF DEFAULT

The events of default in Schedule 10 of the Common Terms Agreement (or the events of default of any amended, supplemented, refinanced or replacement Senior Loan Facilities) (each, an “Event of Default”) shall apply mutatis mutandis to the Notes where the context permits such construction, and to the extent the context does not permit such construction, such provisions shall apply as closely as possible under the circumstances. Any and all waivers of a Default or an Event of Default given, or deemed given, by the holders of the Senior Indebtedness (or any agent or adviser acting on their behalf) under the Senior Loan Facilities shall apply to the Notes with the same effect as if the waiver had been given by the holders of the Notes.

The name and address of each holder of Notes, and, subject to Section 12.2, each transfer thereof and the name and address of each transferee of one or more Notes shall be registered in such register. Prior to due presentment for registration of transfer, the Person in whose name any Note shall be registered shall be deemed and treated as the owner and holder thereof for all purposes hereof, and the Company shall not be affected by any notice or knowledge to the contrary.

12.2. | Transfer and Exchange of Notes

Except as provided in the Deed of Appointment and Priority or in Section 7.2 hereof, the rights of each holder of Notes under this Agreement and the Notes may not be assigned or transferred without the consent of the holders of the Senior Indebtedness, such consent not to be unreasonably withheld. Except as provided in the Deed of Appointment and Priority, the rights of each holder of Notes under this Agreement and the Notes may not be assigned or transferred without the prior written consent of the Company. Subject to compliance with applicable law, obtaining the requisite consents and to the execution of deeds of accession acceptable to the holders of the Senior Indebtedness and the Company, upon surrender of any Note at the principal executive office of the Company for registration of transfer or exchange (and in the case of a surrender for registration of transfer, duly endorsed or accompanied by a written instrument of transfer duly executed by the registered holder of such Note or his attorney duly authorized in writing and accompanied by the address for notices of each transferee of such Note or part thereof), the Company shall execute and deliver, at the Company’s expense (except as provided below), one or more new Notes (as requested by the holder thereof) in exchange therefor, in an aggregate principal amount equal to the unpaid principal amount of the surrendered Note. Each such new Note shall be payable to such Person as such holder may request and shall be substantially in the form of Exhibit 1. Each such new Note shall be dated and bear interest from the date to which interest shall have been paid on the surrendered Note or dated the date of the surrendered Note if no interest shall have been paid thereon. The Company may require payment of a sum sufficient to cover any stamp tax or governmental charge imposed in respect of any such transfer of Notes. Each Note may be transferred only in whole, and not in part. Any transferee, by its acceptance of a Note registered in its name (or the name of its nominee), shall be deemed to have made the representations set forth in Schedule B as of the date of transfer and shall be deemed to have agreed to, and shall be subject to, all terms and provisions of this Agreement and the Notes.

12.3. | Replacement of Notes

Upon receipt by the Company of evidence reasonably satisfactory to it of the ownership of and the loss, theft, destruction or mutilation of any Note, and

(a) in the case of loss, theft or destruction, of an indemnity reasonably satisfactory to it, or

(b) in the case of mutilation, upon surrender and cancellation thereof,

the Company at its own expense shall execute and deliver, in lieu thereof, a new Note, dated and bearing interest from the date to which interest shall have been paid on such lost, stolen, destroyed or mutilated Note or dated the date of such lost, stolen, destroyed or mutilated Note if no interest shall have been paid thereon.

7

13. | PAYMENTS ON NOTES

13.1. | Method and Place of Payment

The Company will pay, or arrange for payment of, all sums becoming due on such Note for principal and interest by wire transfer of immediately available funds to an account specified in writing by the holder of such Note. Upon written request of the Company made concurrently with or reasonably promptly after payment or prepayment in full of any Note, you shall surrender such Note for cancellation, promptly after any such request, to the Company at its principal executive office. Prior to any sale or other disposition of any Note held by you, you will surrender such Note to the Company in exchange for a new Note or Notes in accordance with Section 12.2.

All payments made by the Company hereunder shall be made irrespective of, and without any deduction for, any setoff, counterclaim or withholding. If any amount payable hereunder is required by applicable law to be withheld by the Company, then the Company shall pay such additional amount to the Purchaser so that the net amount received by the Purchaser shall equal the payment due to the Purchaser without regard to the amount so withheld.

16. | AMENDMENT AND WAIVER

16.1. | Requirements

Except as otherwise provided in Sections 8 and 10, this Agreement and the Notes may be amended, and the observance of any term hereof or of the Notes may be waived (either retroactively or prospectively), with (and only with) the written consent of the Company and the Required Holders, except that (a) no amendment or waiver of any of the provisions of Section 1, 2, 3 or 4 hereof will be effective as to you unless consented to by you in writing, and (b) no such amendment or waiver may, without the written consent of the holder of each Note at the time outstanding affected thereby, (i) subject to the provisions of Sections 8 and 10, change the amount or time of any prepayment or payment of principal of, or reduce the rate or change the time of payment or method of computation of interest on the Notes, or (ii) change the percentage of the principal amount of the Notes the holders of which are required to consent to any such amendment or waiver.
