STRICTLY PRIVATE & CONFIDENTIAL

Dear Sirs,

PROJECT DREAM – FEE LETTER

We refer to the commitment letter from Shanghai Pudong Development Bank Co., Ltd., Shanghai Branch to the Borrower dated on or about the date hereof (as amended and/or supplemented from time to time, the “Commitment Letter”). This letter (including the agreement constituted by the Borrower’s acknowledgement of its terms) (this “Letter”) is the Fee Letter referred to in the Commitment Letter. Terms defined in the other Underwriting Documents (as defined in the Commitment Letter, and in each case as amended and/or supplemented from time to time) shall have the same meaning and construction in this Letter unless a contrary indication appears herein. In addition:

1. Upfront Fee

The Borrower agrees to pay (or procure to be paid) to the Mandated Lead Arranger a non-refundable upfront fee (the “Upfront Fee”) in US$ as follows:

(i) if the Facility Agreement is executed and the Facility is utilized, (x) an amount equal to US$5,957,000 (being 3.7 per cent. flat on the amount of the Facility), which fee will be paid on the first Drawdown Date;

(ii) if the Facility Agreement is executed and the Acquisition under the Merger Agreement is consummated within 9 months after countersignature by the Borrower to the Commitment Letter, but the Facility is not utilized, an amount equal to US$4,347,000 (being 2.7 per cent. flat on the amount of the Facility), which fee will be paid within 5 business days upon the written notice of the Mandated Lead Arranger; or

(iii) if the Facility Agreement is executed but the Facility is not utilized within 9 months after countersignature by the Borrower to the Commitment Letter, an amount which is calculated at a rate of 1.32 per cent. (on an annualized basis) based on the amount of the Facility and such amount will accrue from day to day and shall be computed on the basis of the actual number of days elapsed and a year of 360 days, which fee will be paid on the last day of 9 months from the countersignature by the Borrower to the Commitment Letter; for the avoidance of doubt, if conditions set forth under paragraph (ii) above are satisfied (i.e., the Facility Agreement is executed and the Acquisition under the Merger Agreement is consummated within 9 months after countersignature by the Borrower to the Commitment Letter, but the Facility is not utilized), the Upfront Fee under paragraph (ii) above shall apply.
