The right in favor of the holders of the Notes to require the Company to repurchase the Notes

Although none of the Company’s controlling shareholders (as defined in the Listing Rules), including WRL, are parties to the Purchase Agreement or the Indenture, the Indenture will contain a change of control provision that would, if triggered, give rise to a right in favor of the holders of the Notes to require the Company to repurchase the Notes. The circumstances that will constitute a change of control include:

(1) the consummation of any transaction that results in any party other than Mr. Stephen A. Wynn and his related parties becoming the direct or indirect owner of more than 50% of the outstanding voting stock of WRL;

(2) the first day on which a majority of the members of the board of directors of either the Company or WRL are not directors who were on the board at the date of the Indenture, or directors who were nominated, elected, or appointed by a majority of the directors who were on the board at the date of the Indenture;

(3) the first day on which WRL ceases to own, directly or indirectly, a majority of the outstanding issued share capital (including warrants, options or other rights convertible into share capital) of the Company; and

(4) WRL consolidates with, or merges with or into, any other party or sells, assigns, conveys, transfers, leases or otherwise disposes of all or substantially all of its assets to any party, or any party consolidates with, or merges with or into, WRL in any such event pursuant to a transaction in which any of the outstanding voting stock of WRL is converted into or exchanged for cash, securities or other property, other than any such transaction where the voting stock of WRL outstanding immediately prior to such transaction is converted into or exchanged for voting stock that results in WRL holding a majority of the voting stock of the transferee or surviving party.

Reasons for the Notes Issue

The Board believes that the Notes Issue represents a timely opportunity for the Company to supplement the funding of the Group’s business. The Board also believes that the Notes Issue will further strengthen the liquidity position of the Group and provide long-term capital to the Company, and that the Notes Issue will further extend the profile of the Group and improve its ability to access the international debt capital markets to support the growth of the Group in the future.

Proposed use of proceeds

The Company estimates that the net proceeds from the offering of the Notes will be approximately US$591.5 million after deducting the discounts and commissions of the Initial Purchasers and estimated offering expenses payable by the Company. We intend to use the net proceeds from the offering for working capital requirements and general corporate purposes.

Listing

The Company proposes to seek a listing of the Notes on the Stock Exchange and has received an eligibility letter from the Stock Exchange for the listing of the Notes. Admission of the Notes to the Stock Exchange and quotation of any Notes on the Stock Exchange is not to be taken as an indication of the merits of the Company or the Notes.

Ratings

The Notes are expected to receive a rating of Ba2 by Moody’s Investors Service, Inc. and BB by Standard & Poor’s Rating Services, a division of the McGraw Hill Companies, Inc. A security rating is not a recommendation to buy, sell or hold securities and may be subject to suspension, reduction or withdrawal at any time by the assigning rating agency.
