Calculation of Filing Fee

Transaction valuation*
$1,494,980,186.70 Amount of filing fee**
$45,895.89

*Estimated for purposes of calculating the amount of filing fee only. The calculation assumes the purchase of all outstanding ordinary shares of STATS ChipPAC Ltd., a company organized under the laws of Singapore, other than the shares owned by the Offerors, at a purchase price of S$1.75 per share, net to the seller in cash. As of March 9, 2007, there were 2,016,277,910 ordinary shares outstanding, of which 712,228,050 shares are owned by the Offerors. As a result, this calculation assumes the purchase of 1,304,049,860 shares. The transaction valuation of S$2,282,087,255.00 has been translated at US$1.00=S$1.5265, the Bloomberg composite U.S. dollar to Singapore dollar exchange rate at the close of the New York market on March 12, 2007.

**The amount of filing fee, calculated in accordance with Rule 240.0-11 of the Securities Exchange Act of 1934, as amended, and Fee Rate Advisory No. 6 for fiscal year 2007, equals $30.70 per $1,000,000 of the transaction value, or $45,895.89.
