Three Months Ended June 30, 2008

For the second quarter 2008, sales increased 73% to $16.5 million, compared to $9.5 million in the second quarter 2007.

Government orders after the earthquake generated about $4.6 million, which are not expected to recur in future periods. Sales and other amounts, which are reported here in US dollars, were also affected by the strengthening of the Chinese RMB against the US dollar in the last year.
