filed on February 8, 2008 (the "Original Schedule 13G" and the Original Schedule
13G as amended, the "Schedule 13G") with respect to shares of common stock, par
value $0.0001 per share (the "Common Stock") of Solarfun Power Holdings Co.,
Ltd., a Cayman Islands corporation (the "Company"). Capitalized terms used

     As of the date of this filing, (i) Highbridge International LLC
beneficially owns 1,606,940 Ordinary Shares and $45,700,000 aggregate principal
amount of Convertible Senior Notes due January 15, 2018 (the "Notes")
convertible into 2,389,543 ADSs, which represent 11,947,715 Ordinary Shares,
(ii) Highbridge Convertible Arbitrage Master Fund, L.P no longer beneficially

Ordinary Shares beneficially owned by Highbridge International LLC and the
$45,700,000 aggregate principal amount of the Notes convertible into 2,389,543

LLC, Glenn Dubin and Henry Swieca disclaims beneficial ownership of Ordinary
Shares owned by Highbridge International LLC.

Highbridge Convertible Arbitrage Master Fund, L.P. no longer beneficially owns
any Ordinary Shares of the Company, and (iii) each of Highbridge Capital
