Each ADS represents the right to receive five ordinary shares. Any securities registered hereunder may be sold separately or in combination with other securities registered hereunder. The securities registered also include such indeterminate number of ordinary shares and ordinary shares in the form of ADSs as may be issued upon exercise of warrants or pursuant to the antidilution provisions of any such warrants. In addition, pursuant to Rule 416 under the Securities Act of 1933, as amended, or the Securities Act, the shares being registered hereunder include such indeterminate number of ordinary shares as may be issuable with respect to the shares being registered hereunder as a result of stock splits, stock dividends or similar transactions. The proposed maximum per security and aggregate offering prices per class of securities will be determined from time to time by the Registrant in connection with the issuance by the Registrant of the securities registered hereunder and is not specified as to each class of security. Separate consideration may or may not be received for securities that are issuable on exercise, conversion or exchange of other securities. The Registrant is relying on Rules 456(b) and 457(r) under the Securities Act to defer payment of the entire registration fee. In connection with the securities offered hereby, the Registrant will pay "pay-as-you-go registration fees" in accordance with Rule 456(b) under the Securities Act. The Registrant will calculate the registration fee applicable to an offer of securities pursuant to this registration statement based on the fee rate in effect on the date of such fee payment.</ffd:OfferingNote>

Pursuant to Rule 457(p), the filing fee of $20,404.08 in connection with such $185,154,964.00 of unsold unallocated universal shelf securities may be offset against the total filing fee due for this registration statement. Pursuant to Rule 457(p), the offering of such $185,154,964.00 of unsold unallocated universal shelf securities under the Prior Registration Statement will be deemed terminated as of the time of the filing of this registration statement.</ffd:TermntnCmpltnWdrwl>
