The exact applicable price and effective date for the notes may not be as set forth in the table above, in which case:

• if the actual applicable price is between two applicable prices listed in the table above, or the actual effective date is between two dates listed in the table above, we will determine the number of additional ADSs to be added in respect of the notes by linear interpolation between the numbers of additional ADSs set forth for the two applicable prices in the table above, or for the two dates based on a 365-day year, as applicable;

• if the actual applicable price is greater than US$90.00 per ADS (subject to adjustment), we will not increase the conversion rate; and

• if the actual applicable price is less than US$31.00 per ADS (subject to adjustment), we will not increase the conversion rate.

In no event will the conversion rate for the notes exceed 32.2581 ADSs per US$1,000 principal amount. We will adjust this maximum conversion rate in the same manner in which, and for the same events for which, we must adjust the conversion rate as described in the prospectus under “— Conversion Rights — Adjustments to the Conversion Rate”.
