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.

This Amendment No. 30 amends and supplements the Tender Offer Statement and Rule 13E-3 Transaction Statement filed under cover of Schedule TO (this “Schedule TO”) with the Securities and Exchange Commission (“SEC”) on March 16, 2007 by Singapore Technologies Semiconductors Pte Ltd (“STSPL”), a company incorporated under the laws of Singapore and a wholly-owned subsidiary of Temasek Holdings (Private) Limited, a company incorporated under the laws of Singapore (“Temasek”), and by Temasek. This Schedule TO relates to the offer by STSPL to purchase all outstanding ordinary shares (“Ordinary Shares”) (including Ordinary Shares represented by American Depositary Shares) of STATS ChipPAC Ltd., a company organized under the laws of Singapore (the “Company”), not owned by Temasek or STSPL, upon the terms and subject to the conditions set forth in the Offer to Purchase, dated March 16, 2007 (the “Offer to Purchase”), and the related Form of Acceptance and Authorisation, Form of Acceptance and Transfer and ADS Letter of Transmittal (which, as amended or supplemented from time to time, together constitute the “Offer”). This Amendment also constitutes Amendment No. 15 to the Schedule 13D, originally filed with the Securities and Exchange Commission on April 23, 2007 (the “Schedule 13D”).

At 5:30 PM Singapore time, 5:30 AM New York City time, on Friday, May 18, 2007, the Offer closed. According to the report of the receiving and tender agents for the Offer, STSPL has received valid acceptances of the Offer in respect of 945,785,049 Ordinary Shares (including Ordinary Shares represented by 36,303,474 ADSs), as well as US$134,500,000 principal amount of Convertible Subordinated Notes due 2008. No acceptances have been received in respect of the Convertible Notes due 2008. Upon the final settlement of the Offer, STSPL and its concert parties will hold a total of 83.1% of the outstanding Ordinary Shares (including Ordinary Shares and ADSs held by STSPL as at the announcement of the Offer on March 1, 2007 and Ordinary Shares acquired or agreed to be acquired by STSPL after March 1, 2007 and up to 5:30 PM Singapore time, 5:30 AM New York City time, on May 18, 2007, other than pursuant to valid acceptances of the Offer). The press release announcing the foregoing has been filed as Exhibit (a)(1)(LIX) hereto and is incorporated herein by this reference.

In addition, this Amendment amends, restates and supplements the disclosure in the Offer to Purchase for purposes of Item 6 (“Purposes of the Transaction and Plans or Proposals”) of the Schedule TO, Item 6 (“Purposes of the Transaction and Plans or Proposals”) of the Schedule 13E-3 and Item 4 (“Purpose of the Transaction”) of the Schedule 13D as follows:

As previously disclosed, STSPL intends to continue to review its investment in STATS ChipPAC now that the Offer is completed. STSPL currently intends to continue to seek to acquire additional Ordinary Shares, ADSs and Convertible Notes, through open market purchases, privately negotiated transactions or otherwise, upon such terms and at such prices as STSPL shall determine, which may be more or less than the price offered in the Offer, subject to applicable law and regulations. In that regard, under the Singapore Code, STSPL may acquire Ordinary Shares, ADSs or Convertible Notes; however, for the period of six months after May 18, 2007, it may not acquire Ordinary Shares, ADSs or Convertible Notes, or make a second offer for the Ordinary Shares, ADSs or Convertible Notes, at a price higher than the price paid in the Offer (S$1.75 per Ordinary Share, S$17.50 per ADS or the “see-through” prices for the Convertible Notes), except with the consent of the Singapore Securities Industry Council.

As previously disclosed, the SGX-ST may suspend the listing of the Ordinary Shares on the SGX-ST if STSPL and other substantial shareholders (i.e., shareholders who have an interest in not less than 5% of the issued Ordinary Shares) own more than 90% of the issued Ordinary Shares. As STSPL currently owns 83.07% of the issued Ordinary Shares, and STATS ChipPAC has received notice that one other substantial shareholder has voting control over 5.02% and dispositive but non-voting authority over an additional 1.84% of the issued Ordinary Shares, further purchases of Ordinary Shares and ADSs by STSPL or any other shareholder may result in the suspension of the listing of the Ordinary Shares on the SGX-ST. Further purchases of Ordinary Shares or ADSs also may result in the delisting of the ADSs from Nasdaq and the termination of registration of the Ordinary Shares and the ADSs under the Exchange Act.

Even if STSPL does not make any further purchases, STSPL may seek to cause STATS ChipPAC to voluntarily terminate the listing of its Ordinary Shares on the SGX-ST or the listing of its ADSs on NASDAQ, or both, or to terminate the Deposit Agreement through which the ADS program is operated, subject to compliance with applicable law and listing requirements. STSPL may also seek to cause STATS ChipPAC to terminate the registration of its Ordinary Shares and ADSs under the U.S. Securities Exchange Act of 1934 if the applicable requirements for the termination of registration are satisfied.

This Amendment also amends the disclosure in Item 8 (“Interest in Securities of the Subject Company”) and Item 11 (“Interest in Securities of the Subject Company”) of Item 13 (“Information Required by Schedule 13E-3”) of the Schedule TO and Item 5 (“Interest in Securities of the Issuer”) of the Schedule 13D to reflect STSPL’s beneficial ownership of 1,838,819,759 Ordinary Shares (including Ordinary Shares represented by ADSs and Ordinary Shares into which the US$134,500,000 principal amount of Convertible Subordinated Notes due 2008 beneficially owned by STSPL may be converted), representing 84.2% of the issued Ordinary Shares (including in the numerator and the denominator the Ordinary Shares issuable upon a conversion of the Convertible Subordinated Notes due 2008 beneficially owned by STSPL).

Since the filing of Amendment No. 14 to the Schedule 13D, STSPL (and through its ownership of STSPL, Temasek) has acquired beneficial ownership of the following additional Ordinary Shares:

•

As of 5:30 p.m. Singapore time, 5:30 a.m. New York City time, on May 18, 2007, STSPL had acquired beneficial ownership of an additional 35,078,737 Ordinary Shares (including Ordinary Shares represented by 72,313 ADSs) in respect of which acceptances have been tendered pursuant to the Offer.

•

On May 18, 2007, STSPL acquired beneficial ownership of an additional 35,668,000 Ordinary Shares through market purchases on the SGX-ST at a price of S$1.75 per share.

The aggregate purchase price for such additional Ordinary Shares is S$123,806,789.75.
