Directed ADSs:		At the issuer’s request, the underwriter has reserved for sale, at the price to public, 1,000,000 ADSs for Good Energies II LP, an affiliate of the issuer. The number of ADSs available for sale to the general public will be reduced by the number of ADSs reserved for Good Energies II LP.
Concurrent Offering:		Concurrently with this offering of ADSs, the issuer is offering, by means of a separate private placement, US$150,000,000 aggregate principal amount of its 3.50% Convertible Senior Notes due January 15, 2018 (the “convertible notes”) (or US$172,500,000 aggregate principal amount of convertible notes if the initial purchasers exercise their option to purchase additional convertible notes in full). The net proceeds from the sale of the convertible notes, offered concurrently with this offering, will be approximately US$144.5 million after deducting the initial purchasers’ discount and estimated offering expenses. If the initial purchasers exercise in full their option to acquire additional convertible notes, the net proceeds will be approximately US$168.8 million. The delivery of the ADSs is contingent upon the closing of the concurrent offering of the convertible notes, and the closing of the offering of the convertible notes is contingent upon the delivery by the issuer of the ADSs.

Use of Proceeds:		The issuer will not receive any proceeds from the sale of the ADSs in this offering. An affiliate of the underwriter will receive all the proceeds from the sale of the ADSs. Such affiliate has informed the issuer that it intends to use the short position created by the repurchase provisions of a share issuance and repurchase agreement dated January 23, 2008 and the concurrent sale of the ADSs by means of this offering to facilitate transactions by which investors in the issuer’s convertible notes may hedge their investments through privately negotiated transactions. The share issuance and repurchase agreement will terminate on February 15, 2018, or, if earlier, the date as of which the issuer terminates such agreement at any time after the entire principal amount of the convertible notes ceases to be outstanding as a result of conversion, repurchase, cancellation or redemption, or earlier in certain circumstances.
Offering Expenses:		The expenses of this offering and the concurrent private placement of the convertible notes are estimated to be US$1,525,320 (excluding underwriting discounts and commissions payable in connection with the concurrent private placement of the convertible notes), including SEC registration fees of US$4,820, Financial Industry Regulatory Authority filing fees of US$15,500, printing expenses of approximately US$275,000, legal fees of approximately US$850,000, accounting fees of approximately US$200,000, and travel and other out-of-pocket expenses of approximately US$180,000.

Capitalization:

The following table sets forth the issuer’s capitalization, as of September 30, 2007, on an actual basis and on an adjusted basis to reflect the sale of the ADSs pursuant to the share issuance and repurchase agreement (assuming the underwriter does not exercise its option to purchase additional ADSs) and the sale of the issuer’s convertible notes (assuming the initial purchasers do not exercise their option to purchase additional convertible notes).
