Approximate date of commencement of proposed sale to the public: As soon as practicable following the effectiveness of this Registration Statement, satisfaction or waiver of the other conditions to closing of the merger described herein and consummation of the merger.

If this Form is filed to register additional securities for an offering pursuant to Rule 462(b) under the Securities Act, check the following box and list the Securities Act registration statement number of the earlier effective registration statement for the same offering. ¨

If this Form is a post-effective amendment filed pursuant to Rule 462(d) under the Securities Act, check the following box and list the Securities Act registration statement number of the earlier effective registration statement for the same offering. ¨

The Registrant hereby amends this Registration Statement on such date or dates as may be necessary to delay its effective date until the Registrant shall file a further amendment which specifically states that this Registration Statement shall thereafter become effective in accordance with Section 8(a) of the Securities Act of 1933 or until the Registration Statement shall become effective on such date as the Commission, acting pursuant to said Section 8(a), may determine.

This Registration Statement contains the Proxy Statement/Prospectus (the “Proxy Statement/Prospectus”) relating to (i) the solicitation of proxies in connection with the special meeting (the “ChipPAC Special Meeting”) of stockholders of ChipPAC, Inc., a Delaware corporation (“ChipPAC”), to approve and adopt the Agreement and Plan of Merger and Reorganization, dated as of February 10, 2004 (the “Merger Agreement”), among ST Assembly Test Services Ltd, a Singapore public company limited by shares (“STATS”), Camelot Merger, Inc., a Delaware corporation and a wholly owned subsidiary of STATS (“Camelot Merger”), and ChipPAC, and the merger (the “Merger”) of Camelot Merger with and into ChipPAC, with ChipPAC continuing as the surviving corporation and a wholly owned subsidiary of STATS, and (ii) the offering and issuance of American Depositary Shares of STATS (the “STATS ADSs”), each representing ten ordinary shares, par value S$0.25 per share (the “STATS Ordinary Shares”), of STATS, in connection with the proposed Merger. The complete Proxy Statement/Prospectus in connection with the Merger follows immediately after this Explanatory Note, except that the Proxy Statement/Prospectus to be delivered to ChipPAC’s stockholders will not include the notice (the “STATS Notice”) of extraordinary general meeting of the shareholders of STATS (the “STATS EGM”) that is immediately following the letter to the shareholders of STATS and ChipPAC that is immediately following this Explanatory Note. The Shareholders Circular (the “Shareholders Circular”) to be delivered to STATS’ shareholders in connection with the STATS EGM will be identical to the Proxy Statement/Prospectus, except that the STATS Notice will replace the notice of the ChipPAC Special Meeting. At the STATS EGM, STATS shareholders will be asked to approve the issuance of STATS Ordinary Shares underlying the STATS ADSs in connection with the Merger and other matters related to the Merger.

We are pleased to report that the boards of directors of ST Assembly Test Services Ltd and ChipPAC, Inc. each have approved a merger involving the two companies. Before STATS and ChipPAC can complete the merger, we must obtain the approval of the respective companies’ shareholders. We are sending you this document to ask you to vote in favor of the merger and the other matters related to the merger.

In the merger, a subsidiary of STATS will merge with and into ChipPAC and ChipPAC will become a wholly owned subsidiary of STATS. As a result of the merger, ChipPAC stockholders will be entitled to receive 0.87 American Depositary Shares of STATS (STATS ADSs) in exchange for each of their shares of ChipPAC Class A common stock. STATS currently expects to issue approximately 85,741,262 STATS ADSs upon the consummation of the merger (such STATS ADSs will represent the right to receive approximately 857,412,623 STATS ordinary shares). STATS ADSs are quoted on the Nasdaq National Market under the symbol “STTS”. Each STATS ADS represents the right to receive ten ordinary shares, par value S$0.25 per share (STATS ordinary shares), of STATS. STATS ordinary shares are listed on the Singapore Exchange Securities Trading Limited (the Singapore Exchange) under the symbol “ST Assembly”.

STATS will hold an extraordinary general meeting of its shareholders to consider and vote on certain matters related to the merger and ChipPAC will hold a special meeting of its stockholders to consider and vote on the merger and related matters. The merger is conditioned upon, among other things, the approval of STATS shareholders and ChipPAC stockholders.

YOUR VOTE IS VERY IMPORTANT. Whether or not you plan to attend the STATS or ChipPAC shareholders meeting, please take the time to vote by completing, signing, dating and returning the accompanying proxy card. If you are a STATS shareholder, you must return the proxy card in accordance with the instructions printed thereon as soon as possible and in any event so as to arrive at STATS registered office no later than 10:00 a.m., Singapore time on August 2, 2004. If you are a ChipPAC stockholder, you must return the proxy card no later than 9:00 a.m., Pacific time on August 4, 2004 in the enclosed self-addressed stamped envelope. Returning the proxy does NOT deprive you of your right to attend the shareholders meeting and to vote your shares in person.

This document provides detailed information concerning the merger, the STATS extraordinary general meeting and the ChipPAC special meeting. Additional information regarding STATS and ChipPAC has been filed with the U.S. Securities and Exchange Commission and is publicly available. We encourage you to read carefully this entire document, including all of its annexes, and we especially encourage you to read the section entitled “ Risk Factors” beginning on page 31.

We enthusiastically support the proposed merger of STATS and ChipPAC, and we join with the members of our board of directors in recommending that you vote FOR the merger and related matters.

Neither the U.S. Securities and Exchange Commission nor any state securities commission has approved or disapproved the STATS ADSs or STATS ordinary shares to be issued by STATS under this document or passed upon the adequacy or accuracy of this document. Any representation to the contrary is a criminal offense.

The Singapore Exchange assumes no responsibility for the correctness of any statements made, reports contained or opinions expressed in this document.

We have fixed the close of business on June 16, 2004 as the record date for the determination of our stockholders entitled to vote at the meeting. Only holders of record of shares of ChipPAC Class A common stock on that date are entitled to notice of, and to vote at, the special meeting or any adjournment or postponement of the special meeting. You may vote in person or by proxy. To grant your proxy to vote your shares, you must complete and return the enclosed proxy card or grant your proxy by telephone or Internet. Granting your completed proxy in advance of the special meeting will not prevent you from voting in person at the special meeting.

Whether or not you plan to attend the special meeting in person, you are urged to read this document carefully and then sign, date and return the enclosed proxy card in the enclosed postage-paid envelope by following the instructions on the accompanying proxy card.

The merger will constitute a “change of control” as defined in the indenture governing the ChipPAC senior subordinated notes and accordingly, the holders of the ChipPAC senior subordinated notes will have the right to require ChipPAC to repurchase such notes at a purchase price in cash equal to 101% of the principal amount plus any accrued and unpaid interest as of the date of repurchase.

The merger will not constitute a “change of control” as defined in the indenture governing the ChipPAC 2.5% convertible subordinated notes, but may constitute a “change of control” as defined in the indenture governing the ChipPAC 8% convertible subordinated notes.

See “STATS Proposals at the STATS Extraordinary General Meeting” beginning on page 122.

For ChipPAC, the affirmative vote of a majority of the shares of ChipPAC Class A common stock outstanding and entitled to vote at the ChipPAC stockholders meeting is required to approve and adopt the merger agreement and to approve the merger.

The ChipPAC special meeting will be held at 47400 Kato Road, Fremont, California 94583 on August 4, 2004, starting at 9:00 a.m, Pacific time.

Resolution 1: to approve the issuance of the new STATS ordinary shares underlying the STATS ADSs that will be issued to ChipPAC stockholders on the terms and subject to the conditions set out in the merger agreement;

Resolution 3: to approve the offer and grant of the STATS substitute options and the issuance of the new STATS ordinary shares

as may be required to be issued pursuant to the exercise of such STATS substitute options;

Resolution 4: to approve the entry into any supplemental indenture or other agreement in connection with the assumption by STATS of certain obligations under the ChipPAC convertible subordinated notes and the issuance of new STATS ordinary shares underlying the STATS ADSs as may be required to be issued pursuant to the conversion of the ChipPAC convertible subordinated notes into STATS ADSs after the merger;

Resolution 11: to appoint PricewaterhouseCoopers, Singapore as auditors to STATS, effective as of the date this STATS resolution 11 is approved by the STATS shareholders; and

Each of the STATS resolutions will be voted on separately at the STATS extraordinary general meeting. If any of STATS resolutions 1 through 8 and 12 do not receive the requisite approval of the STATS shareholders, none of STATS resolutions 1 through 10 and 12 will be deemed approved by the STATS shareholders and the merger will not be consummated. STATS resolutions 9 and 10 are contingent upon the consummation of the merger and, even if such resolutions receive the requisite STATS shareholder approval, will be deemed approved by STATS shareholders only if the merger is consummated. STATS resolution 11 is not contingent upon the consummation of the merger and therefore will be approved if it receives the requisite STATS shareholder approval.

At the ChipPAC special meeting, ChipPAC stockholders will vote to approve and adopt the merger agreement and to approve the merger.

ChipPAC stockholders who collectively held approximately 17.9% of the outstanding ChipPAC Class A common stock as of June 16, 2004 (the ChipPAC record date) have entered into a voting

agreement (the ChipPAC voting agreement) requiring them to vote all of the shares of ChipPAC Class A common stock owned of record by such stockholders in favor of the adoption and approval of the merger agreement and in favor of the approval of the merger.

After carefully reading and considering the information contained in this document, ChipPAC stockholders should complete and mail their signed proxy card in the enclosed return envelope or vote by Internet or by telephone, in each case as soon as possible so that their shares may be represented at the ChipPAC special meeting. ChipPAC stockholders should complete and mail a proxy as instructed, even if they currently plan to attend the ChipPAC special meeting in person, to ensure that their votes are counted.

Enclosed with this document are a STATS ADS Voting Instructions Card and a STATS Depositary Notice of STATS Extraordinary General Meeting, which explain how a holder of STATS ADSs may instruct the STATS depositary to vote the STATS ordinary shares underlying such holder’s STATS ADSs at the STATS extraordinary general meeting. The STATS ADS Voting Instructions Card must be completed and received by the STATS depositary no later than 10:00 a.m., New York time, on July 28, 2004 to ensure that the STATS depositary votes the STATS ordinary shares underlying the STATS ADSs covered by such voting instructions card.

Holders of STATS ADSs who hold their STATS ADSs in “street name” should contact their broker, who can provide directions on how to instruct the broker to exercise the voting rights of the STATS ordinary shares represented by the STATS ADSs. Brokers will not exercise the voting rights with respect to any STATS resolutions unless the broker receives appropriate instructions from the holder of the STATS ADSs.

If you are a ChipPAC stockholder, you may change your vote at any time before the ChipPAC special meeting by sending to ChipPAC’s secretary a proxy with a later date. Alternatively, you may revoke your proxy by delivering to ChipPAC’s secretary a written revocation prior to the ChipPAC special meeting.

Both STATS shareholders and ChipPAC stockholders may change their vote by voting in person at their respective shareholders meeting.

If a STATS shareholder submits a proxy and does not indicate how such shareholder’s STATS ordinary shares should be voted, the proxy holder may vote or abstain from voting as the proxy holder sees fit.

If a ChipPAC stockholder returns a proxy and does not indicate how the ChipPAC Class A common stock is to be voted, the proxy will be counted as a vote to adopt and approve the merger agreement and to approve the merger.

Please do not send in any ChipPAC stock certificates until you receive these written instructions.

This summary highlights selected information from this document. This summary may not contain all of the information that is important to you.

STATS is a leading semiconductor test and assembly provider to fabless companies (semiconductor companies that do not have their own manufacturing facilities), vertically integrated semiconductor device manufacturers and independent semiconductor wafer foundries. With its principal operations in Singapore and global operations in the United States, United Kingdom, Japan, China and Taiwan, STATS offers full back-end turnkey solutions, including pre-production services, wafer probe, assembly, final test and drop shipment, to customers worldwide. STATS’ expertise is in testing mixed-signal semiconductors, or semiconductors which combine analog and digital circuits in each chip, which are extensively used in fast growing communications applications, such as data networking, broadband and mobile communications. STATS also tests a wide range of digital semiconductors. STATS also offers advanced assembly services and has developed a wide array of traditional and advanced leadframe and laminate-based products to serve some of the world’s technological leaders. Leadframe packages are characterized by a semiconductor die encapsulated in a plastic mold compound with metal leads surrounding the perimeter of the package. Laminate packages include ball grid array packages that employ leads, or interconnects, on the bottom of the package in the form of small bumps, or balls, in a matrix or array pattern and utilize a plastic or tape laminate substrate.

ChipPAC is a full portfolio provider of semiconductor packaging, design, assembly, test and distribution services. ChipPAC is a leader in advanced packaging services that address the needs of semiconductors used in wireless communications, including flip-chip, chip-scale and stacked die technologies. In flip chip packages, the semiconductor device is flipped or placed facing downwards and connected to a package, substrate or board. The chip typically has bumps resting on bond pads in a peripheral or array design. Chip-scale packages are high

density packages that approximate the size of the chip itself and which have a greater chip area to package area ratio. Stacked die technologies allow for multiple stacking of dies or semiconductor devices, in a package. ChipPAC combines a history of innovation and service with more than a decade of experience satisfying some of the largest customers in the industry. With advanced process technology capabilities and a global manufacturing presence spanning Korea, China and Malaysia, ChipPAC has a reputation for providing dependable, high quality packaging solutions.

Camelot Merger, Inc. is a wholly owned subsidiary of STATS, which was formed solely for the purpose of effecting the merger and has no assets, liabilities or historical results of operations.

The terms and conditions of the merger are contained in the merger agreement, which is attached as Annex A to this document. Please carefully read the merger agreement in its entirety as it is the legal document that governs the merger.

In the merger, Camelot Merger, Inc., a newly formed, wholly owned subsidiary of STATS, will merge into ChipPAC. After the merger, ChipPAC will be a wholly owned subsidiary of STATS, and ChipPAC stockholders will become STATS shareholders. The STATS ADSs to be received in the merger will be quoted on the Nasdaq National Market under the symbol “STTS”. STATS ordinary shares are listed on the Singapore Exchange under the symbol “ST Assembly”.

STATS currently anticipates that existing STATS shareholders and ChipPAC stockholders will own approximately 55.7% and 44.3%, respectively, of the STATS ordinary shares outstanding after the merger, based on the number of STATS ordinary shares and ChipPAC Class A common stock outstanding as of June 16, 2004. STS, an indirectly owned subsidiary of Temasek Holdings, the principal holding company through which the corporate investments of the Government of Singapore are held, is currently expected to beneficially own approximately 33.0% of the STATS ordinary shares outstanding after the consummation of the merger.

Each share of ChipPAC Class A common stock will automatically be converted into the right to receive 0.87 STATS ADSs and cash in place of any fractional STATS ADS. Each STATS ADS represents the right to receive ten STATS ordinary shares.

There are a number of significant differences between the rights of holders of ChipPAC Class A common stock and the rights of holders of STATS ADSs or STATS ordinary shares. Examples of such differences include:

In addition, as a foreign private issuer, STATS is subject to requirements under the Securities Act and the Exchange Act that are different from the requirements applicable to ChipPAC prior to the merger. For additional information regarding the rights of holders of STATS ordinary shares and STATS ADSs and a summary of certain material differences between the rights of holders of STATS ordinary shares and holders of ChipPAC Class A common stock, see “Description of STATS Ordinary Shares” beginning on page 140, “Description of STATS American Depositary Shares” beginning on page 144 and “Comparison of Shareholder Rights” beginning on page 153. See also “Risk Factors—Risks related to ownership of STATS ordinary shares or STATS ADS” beginning on page 52.

Each STATS ordinary share and STATS ADS outstanding prior to the merger will remain issued and outstanding as a STATS ordinary share or STATS ADS, as the case may be, after the merger.

When the merger is completed, stock options to purchase shares of ChipPAC Class A common stock granted to ChipPAC employees and directors under the ChipPAC 1999 plan and the ChipPAC 2000 Plan, in each case that are outstanding and not exercised immediately before the effective time of the merger, will be substituted with STATS substitute options to purchase STATS ordinary shares. The number of STATS ordinary shares subject to STATS substitute options and the exercise price of STATS substitute options will be adjusted to account appropriately for the exchange ratio in the merger, subject to certain limitations. Upon exercise of a STATS substitute option, the holder of such STATS substitute option may elect to receive, in lieu of STATS ordinary shares, a number of STATS ADSs equal to the number of STATS ordinary shares subject to the relevant STATS substitute option divided by ten and rounded down to the nearest whole STATS ADS.

The STATS substitute options will be granted under the STATS ChipPAC Ltd. Substitute Share Purchase and Option Plan (the STATS ChipPAC substitute share option plan) or the STATS ChipPAC Ltd. Substitute Equity Incentive Plan (the STATS ChipPAC substitute EIP and, together with the STATS ChipPAC substitute share option plan, the STATS ChipPAC substitute option plans), subject to approval by the STATS shareholders at the STATS extraordinary general meeting. For a description of the STATS ChipPAC substitute option plans, please see “STATS Proposals at the STATS Extraordinary General Meeting—Resolution 2” beginning on page 123.

Holders of STATS ordinary shares who are registered with The Central Depository (Pte) Limited (the CDP) or in STATS’ Register of Shareholders (Members) as of 48 hours before the time set for the STATS

extraordinary general meeting (or by 10:00 a.m., Singapore time, on August 2, 2004) will be entitled to vote at the STATS extraordinary general meeting.

Only holders of record of ChipPAC Class A common stock as of the ChipPAC record date are entitled to notice of, and to vote at, the ChipPAC special meeting.

STATS and ChipPAC will only proceed with the merger if the merger and the related matters are approved at the STATS extraordinary general meeting and the ChipPAC special meeting by the requisite vote of STATS shareholders and ChipPAC stockholders, respectively, and the other conditions to the merger are satisfied or waived.

The affirmative vote of a majority of the votes cast at the STATS extraordinary general meeting is required to approve STATS resolutions 1 through 11 and the affirmative vote of not less than three-fourths of the votes cast at the STATS extraordinary general meeting is required to approve the name change of STATS to “STATS ChipPAC Ltd.”, which is a condition to the completion of the merger. If any of STATS resolutions 1 through 8 and 12 do not receive the requisite approval of the STATS shareholders, none of STATS resolutions 1 through 10 and 12 will be deemed approved by the STATS shareholders and the merger will not be consummated. STATS resolutions 9 and 10 are contingent upon the consummation of the merger and, even if such resolutions receive the requisite STATS shareholder approval, will be deemed approved by STATS shareholders only if the merger is consummated. STATS resolution 11 is not contingent upon the consummation of the merger and therefore will be approved if it receives the requisite STATS shareholder approval.

As of June 16, 2004, directors and executive officers of STATS and their affiliates owned, and were entitled to vote, approximately 637,617,050 STATS ordinary shares, or approximately 59.2% of the outstanding STATS ordinary shares. Certain shareholders, directors and officers of STATS and their affiliates, who as of June 16, 2004, together owned a total of approximately 59.2% of the outstanding STATS ordinary shares, have entered into the STATS voting agreement and have agreed to vote all STATS ordinary shares and STATS ADSs owned of record by such shareholders in favor of the issuance of STATS ordinary shares in the merger and certain other matters related to the merger. As a result, approval of STATS resolutions 1 through 8 at the STATS extraordinary general meeting is assured.

The affirmative vote of a majority of the shares of ChipPAC Class A common stock outstanding and entitled to vote at the ChipPAC special meeting is required to approve and adopt the merger agreement and to approve the merger.

As of the ChipPAC record date, directors and executive officers of ChipPAC and their affiliates owned, and were entitled to vote, approximately 17,906,326 shares of ChipPAC Class A common stock, or approximately 18.2% of the outstanding ChipPAC Class A common stock. Certain stockholders and directors of ChipPAC and Mr. McKenna, the President and Chief Executive Officer of ChipPAC and Chairman of the ChipPAC board of

directors, and their affiliates, who as of the ChipPAC record date together owned a total of approximately 17.9% of the outstanding shares of ChipPAC Class A common stock, have entered into the ChipPAC voting agreement and have agreed to vote all shares of ChipPAC Class A common stock owned of record by such stockholders in favor of the adoption and approval of the merger agreement and the approval of the merger.

The STATS board of directors believes that the merger is fair to STATS shareholders and in their best interests, and it recommends that STATS shareholders vote FOR the STATS resolutions related to the merger. In addition, the STATS board of directors has approved the recommendation of the STATS audit committee to appoint PricewaterhouseCoopers, Singapore as auditors to STATS and recommends that STATS shareholders vote FOR STATS resolution 11.

The ChipPAC board of directors believes that the merger is fair to ChipPAC stockholders and in their best interests. The ChipPAC board of directors recommends that ChipPAC stockholders vote FOR the proposal to adopt and approve the merger agreement and to approve the merger.

In connection with the merger, Morgan Stanley Dean Witter Asia (Singapore) Pte (Morgan Stanley), STATS’ financial advisor, delivered a written opinion to the STATS board of directors as to the fairness to STATS, from a financial point of view, of the exchange ratio under the merger agreement. The full text of Morgan Stanley’s opinion, dated as of February 10, 2004, is attached as Annex D to this document. STATS shareholders are encouraged to read this opinion carefully and in its entirety for a description of the procedures followed, the assumptions made, matters considered and the limitations on the review undertaken. Morgan Stanley’s opinion was provided to the STATS board of directors in connection with its evaluation of the fairness to STATS, from a financial point of view, of the exchange ratio under the merger agreement, and does not address any other aspect of the merger and does not constitute a recommendation to any STATS shareholder, STATS ADS holder or ChipPAC stockholder as to how any such holder should vote on any matter related to the merger.

In connection with the merger, Credit Suisse First Boston LLC, ChipPAC’s financial advisor, delivered a written opinion to the ChipPAC board of directors as to the fairness, from a financial point of view, to the holders of ChipPAC Class A common stock of the exchange ratio. The full text of Credit Suisse First Boston’s written opinion, dated February 9, 2004, is attached to this document as Annex E. ChipPAC stockholders are encouraged to read this opinion carefully in its entirety for a description of the procedures followed, assumptions made, matters considered and limitations on the review undertaken. Credit Suisse First Boston’s opinion was provided to the ChipPAC board of directors in connection with its evaluation of the exchange ratio, does not address any other aspect of the proposed merger and does not constitute a recommendation to any ChipPAC stockholder, STATS shareholder or STATS ADS holder as to any matters relating to the merger.

STATS and ChipPAC have agreed that they will not solicit or encourage the initiation of any inquiries regarding any acquisition proposals by third parties. STATS and ChipPAC may respond to unsolicited competing

transaction proposals if required to comply with their respective board of directors’ fiduciary duties. STATS and ChipPAC must promptly notify the other party if it receives any acquisition proposal.

At the effective time of the merger, each of Messrs. Koh Beng Seng, William J. Meder, Teng Cheong Kwee and Quek Swee Kuan will resign from the STATS board of directors and, subject to their election at the STATS extraordinary general meeting, four persons who have been designated by ChipPAC will serve as directors of STATS. ChipPAC has designated Dr. Conn, Mr. McKenna, Mr. Norby and Dr. Park to be nominated for election to the STATS board of directors. In addition, one of Dr. Conn, Mr. Norby and Dr. Park will be appointed to the audit committee of the STATS board of directors (the STATS audit committee). If Mr. McKenna is elected to the STATS board of directors, he will be appointed as Vice Chairman of the STATS board of directors and serve in that capacity and as a director until December 31, 2004. After the completion of the merger and assuming the election of Dr. Conn, Mr. McKenna, Mr. Norby and Dr. Park to the STATS board of directors at the STATS extraordinary general meeting, the STATS board of directors will be composed of the following 11 persons:

Each of STATS’ and ChipPAC’s obligation to consummate the merger is subject to the satisfaction or waiver of a number of conditions, including:

In addition, STATS’ obligation to complete the merger is subject to the satisfaction or waiver of the condition that there not be any continuing default or event of default under the ChipPAC convertible subordinated notes or the ChipPAC senior subordinated notes.

If the closing condition to the merger that STATS and ChipPAC have received either a private letter ruling from the IRS, or an opinion from a nationally recognized law firm, that the exchange of ChipPAC Class A common stock for STATS ADSs in the merger will not result in the recognition of gain under Section 367 of the Internal Revenue Code is not satisfied, STATS and ChipPAC may under the merger agreement waive the condition. In this event, if the merger were to proceed, ChipPAC stockholders would recognize gain on the exchange of ChipPAC Class A common stock for STATS ADSs in the merger. If STATS and ChipPAC decide to waive the condition and wish to proceed with the merger without having received either the private letter ruling or the opinion, which would cause U.S. Holders of ChipPAC Class A common stock to recognize gain, STATS and ChipPAC will re-solicit the approval of ChipPAC stockholders for approval and adoption of the merger agreement and approval of the merger, and will not complete the merger unless such approval is obtained. See “The Merger — Material U.S. federal income tax consequences” beginning on page 93.

STATS and ChipPAC may jointly agree at any time to terminate the merger agreement without completing the merger, even if STATS shareholders have approved the issuance of STATS ordinary shares in the merger and the other matters related to the merger and ChipPAC stockholders have approved and adopted the merger agreement and approved the merger. In addition, either of STATS or ChipPAC may, without the consent of the other party, terminate the merger agreement in various circumstances, including the following:

ChipPAC and STATS have agreed to pay a termination fee to the other party of $40 million if the merger agreement is terminated under certain circumstances.

Neither STATS shareholders nor ChipPAC stockholders are entitled to appraisal or dissenters’ rights in connection with the merger under Singapore law or Delaware law, respectively.

Under the Hart-Scott-Rodino Act, the merger may not be consummated unless certain filings have been submitted to the U.S. Federal Trade Commission (the FTC) and the Antitrust Division of the U.S. Department of Justice (the Antitrust Division) and a required waiting period has expired or been terminated. STATS and ChipPAC filed the required materials on March 9, 2004. The FTC granted early termination of the waiting period effective March 19, 2004.

In addition, under the Korean Monopoly Regulation and Fair Trade Act, as amended, STATS is required to file a share acquisition notification with the Korean Fair Trade Commission (the Korean FTC) within 30 days after the consummation of the merger.

The FTC and the Antitrust Division have the authority to challenge the merger on antitrust grounds before or after the merger is completed. In addition, certain private parties, state attorneys general or other antitrust authorities may challenge the transactions under antitrust laws under certain circumstances. STATS and ChipPAC believe that they will obtain the necessary antitrust clearances. There can be no assurance, however, that a challenge to the merger on antitrust grounds will not be made, or, if such a challenge is made, what the result will be.

On June 3, 2004, STATS announced that the Singapore Exchange granted its in-principle approval for the listing and quotation on the Singapore Exchange of STATS ordinary shares underlying the STATS ADSs to be issued in connection with the merger. Such approval of the Singapore Exchange is not to be taken as an indication of the merits of the issuance of the STATS ordinary shares.

The merger has been structured to qualify as a reorganization, generally tax-free to ChipPAC, STATS and their respective shareholders for U.S. federal income tax purposes. Because the exchange of ChipPAC Class A

common stock for STATS ADSs will represent an exchange of stock of a U.S. corporation for the stock of a non-U.S. corporation, Section 367 of the Internal Revenue Code and the Treasury regulations thereunder prescribe certain requirements that must be met in order for ChipPAC stockholders to avoid gain recognition as a result of the exchange. STATS and ChipPAC have submitted a ruling request to the IRS for the private letter ruling to the effect that, based on certain representations and assumptions, the exchange of ChipPAC Class A common stock for STATS ADSs in the merger will not result in the recognition of gain under Section 367 of the Internal Revenue Code.

In connection with the closing of the merger, STATS and ChipPAC will receive legal opinions from their respective legal counsel that (determined without the application of Section 367 of the Internal Revenue Code) the merger will qualify as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code and that STATS, ChipPAC and Camelot Merger, Inc. will be a party to the reorganization. In addition, it is a condition to the closing of the merger that either the IRS has issued the private letter ruling described above or STATS and ChipPAC have each received an opinion from a nationally recognized law firm to the effect that the exchange of ChipPAC Class A common stock for STATS ADSs in the merger will not result in the recognition of gain under Section 367 of the Internal Revenue Code. The private letter ruling and the tax opinions must not have been withdrawn or modified in any material respect prior to the merger, and will be subject to certain assumptions, representations and qualifications and will be based on the truth and accuracy of certain assumptions and covenants made by STATS and ChipPAC in certificates delivered or to be delivered to the IRS and counsel by the respective managements of STATS and ChipPAC. Under currently applicable Treasury regulations, the Section 367 tax opinion referred to above could not be issued because the exchange of ChipPAC Class A common stock for STATS ADSs in the merger would likely result in the recognition of gain under Section 367 of the Internal Revenue Code unless the IRS issues the requested private letter ruling.

Provided that the conditions set forth in the prior paragraph are satisfied so that the merger qualifies as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code and the exchange of ChipPAC Class A common stock for STATS ADSs in the merger qualifies as not resulting in the recognition of gain under Section 367 of the Internal Revenue Code, a U.S. Holder (as defined below) of ChipPAC Class A common stock will not recognize any gain or loss as a result of the receipt of STATS ADSs in exchange for ChipPAC Class A common stock pursuant to the merger. A U.S. Holder will, however, recognize gain or loss in connection with any cash received by such U.S. Holder in lieu of a fractional STATS ADS.

If the closing condition that either the IRS has issued the private letter ruling or STATS and ChipPAC have received the tax opinions referred to above is not satisfied, STATS and ChipPAC may, under the merger agreement, waive the condition. In such case, if the merger does not qualify as a reorganization, U.S. Holders of ChipPAC Class A common stock will recognize gain or loss on the exchange of ChipPAC Class A common stock for STATS ADSs. If, however, the merger qualifies as a reorganization (determined without the application of Section 367 of the Internal Revenue Code) but the exchange does not qualify for nonrecognition of gain under Section 367 of the Internal Revenue Code, U.S. Holders of ChipPAC Class A common stock will recognize gain (but not loss) on the exchange of ChipPAC Class A common stock for STATS ADSs in the merger. If STATS and ChipPAC decide to waive the condition and wish to proceed with the merger without having received the private letter ruling or the opinions, which would cause U.S. Holders of ChipPAC Class A common stock to recognize gain, STATS and ChipPAC will re-solicit the approval of ChipPAC stockholders for the approval and adoption of the merger agreement and the approval of the merger, and will not complete the merger unless such approval is obtained.

This U.S. federal income tax treatment may not apply to certain ChipPAC stockholders. ChipPAC stockholders are strongly urged to consult their own tax advisors for a full understanding of the merger’s tax consequences.

Certain STATS shareholders, executive officers and directors have entered into the STATS voting agreement with ChipPAC in which each has agreed, among other things, to vote all STATS ordinary shares and STATS ADSs owned of record by such shareholder in favor of the approval of the issuance of STATS ordinary shares in the merger and certain other matters related to the merger and against any action that would delay or prevent the merger. These persons have the right, as of June 16, 2004, to vote a total of 637,617,050 STATS ordinary shares, or approximately 59.2% of the outstanding STATS ordinary shares. As a result, approval of STATS resolutions 1 through 8 at the STATS extraordinary general meeting is assured.

Certain ChipPAC stockholders and directors, and Mr. McKenna, the President, Chief Executive Officer and Chairman of the board of directors of ChipPAC, have entered into the ChipPAC voting agreement with STATS in which each has agreed, among other things, to vote all shares of ChipPAC Class A common stock owned of record by such stockholder in favor of the adoption and approval of the merger agreement and the approval of the merger and against any action that would delay or prevent the merger. Certain of these persons do not own any shares of ChipPAC Class A common stock, but entered into the ChipPAC voting agreement to evidence their support for the merger. The ChipPAC stockholders who entered into the ChipPAC voting agreement have the right, as of the ChipPAC record date, to vote a total of 17,646,587 shares of ChipPAC Class A common stock, or approximately 17.9% of the outstanding ChipPAC Class A common stock.

INTERESTS OF CERTAIN PERSONS IN THE MERGER AND THE RELATED TRANSACTIONS (see page 87)

When considering the recommendations of the STATS board of directors regarding the issuance of the STATS ordinary shares in the merger and the other matters related to the merger, STATS shareholders should be aware of the interests that certain of STATS’ executive officers and directors have in the merger and the related transactions that are different from the interests of STATS shareholders generally, including the employment agreements with STATS that each of the executive officers of STATS has with STATS.

The STATS board of directors was aware of these interests in approving the merger agreement and the merger.

When considering the recommendations of the ChipPAC board of directors regarding the merger agreement and the merger, ChipPAC stockholders should be aware of the interests that certain of ChipPAC’s executive officers and directors have in the merger that are different from the interests of ChipPAC stockholders generally. These interests include, among other things:

The ChipPAC board of directors was aware of these interests in approving the merger agreement and the merger.

The following summary consolidated financial data should be read in conjunction with STATS’ consolidated financial statements and related notes thereto audited by KPMG, independent accountants, included in STATS’ annual reports and other financial information included in STATS’ filings with the SEC. See “Where You Can Find More Information” on page 181.

The consolidated statement of operations data for each of the years ended December 31, 2001, 2002 and 2003 and the consolidated balance sheet data at December 31, 2002 and 2003, which have been prepared in accordance with U.S. generally accepted accounting principles, are derived from STATS’ consolidated financial statements and related notes thereto incorporated by reference in this document.

STATS’ historical financial data as of and for the three months ended March 31, 2003 and 2004, has been derived from, and should be read in conjunction with, STATS’ unaudited condensed consolidated financial statements and related notes thereto that are incorporated by reference into this document. The unaudited results of operations data for the three months ended March 31, 2004, are not necessarily indicative of the results to be expected for any other interim period or for the fiscal year 2004 as a whole. Except as otherwise noted in this document, all references to “$” shall mean U.S. dollars.

The following summary consolidated financial data should be read in conjunction with ChipPAC’s consolidated financial statements and related notes thereto included in ChipPAC’s annual reports and other financial information included in ChipPAC’s filings with the SEC. See “Where You Can Find More Information” on page 181.

The consolidated statement of operations data for each of the years ended December 31, 2001, 2002 and 2003 and the consolidated balance sheet data at December 31, 2002 and 2003, which have been prepared in accordance with U.S. generally accepted accounting principles, are derived from ChipPAC’s consolidated financial statements and related notes thereto incorporated by reference in this document.

ChipPAC’s historical financial data as of and for the three months ended March 31, 2003 and 2004 has been derived from, and should be read in conjunction with, ChipPAC’s unaudited condensed consolidated financial statements and related notes thereto that are incorporated by reference into this document. The unaudited results of operations data for the three months ended March 31, 2004, are not necessarily indicative of the results to be expected for any other interim period or for the fiscal year 2004 as a whole.

The following summary unaudited pro forma condensed combined consolidated financial information gives effect to the proposed merger between STATS and ChipPAC using the purchase method of accounting for the business combination. This data should be read in conjunction with the unaudited pro forma condensed combined consolidated financial statements and related notes thereto, which can be found beginning on page 169.

The unaudited pro forma condensed combined consolidated financial statements have been presented assuming an exchange ratio of 0.87 STATS ADSs in exchange for each share of ChipPAC Class A common stock pursuant to the merger agreement.

There can be no assurance that STATS and ChipPAC will not incur charges in excess of those included in the pro forma total consideration related to the merger or that STATS management will be successful in its effort to integrate the operations of STATS and ChipPAC.

The unaudited pro forma condensed combined consolidated statement of operations information gives effect to the proposed merger as if it had been consummated on January 1, 2003 and combines the historical consolidated statement of operations of STATS for the year ended December 31, 2003 and the three months ended March 31, 2004 with the historical consolidated statement of operations of ChipPAC for the year ended December 31, 2003 and the three months ended March 31, 2004, after giving effect to adjustments arising from applying the purchase method of accounting.

The unaudited pro forma condensed combined consolidated balance sheet information gives effect to the proposed merger as if it had been consummated on March 31, 2004. The unaudited pro forma condensed combined consolidated balance sheet combines the unaudited historical consolidated balance sheet of STATS as of March 31, 2004 with the unaudited historical consolidated balance sheet of ChipPAC as of March 31, 2004, after giving effect to adjustments arising from applying the purchase method of accounting.

The pro forma information is presented for illustrative purposes only and is not necessarily indicative of the operating results or financial position that would have occurred if the proposed merger had been consummated on January 1, 2003 or March 31, 2004, nor is it necessarily indicative of future operating results or financial position. The unaudited pro forma condensed combined consolidated financial statements are based on STATS management’s preliminary estimates of, and good faith assumptions regarding, the adjustments arising from the proposed merger at the time of the filing of this document. The pro forma adjustments are based upon the limited information currently made available to STATS by ChipPAC for purposes of conducting a valuation of ChipPAC’s assets and liabilities. Not all information required to complete such valuation is currently available to STATS, due to, among other things, regulatory restrictions and other considerations regarding the sharing of certain information between possible competitors prior to the consummation of the merger, and as additional information becomes available to STATS, the actual allocation of the merger consideration to the ChipPAC assets acquired and liabilities assumed upon the consummation of the merger could differ materially from current estimates. The actual amounts recorded as of the completion of the merger may differ materially from the information presented in these unaudited pro forma condensed combined consolidated financial statements. The pro forma information should be read in conjunction with the unaudited pro forma condensed combined consolidated financial statements and accompanying notes thereto included in this document and with STATS’ and ChipPAC’s historical consolidated financial statements and related notes thereto incorporated by reference into this document.

The assumptions used in the following pro forma statements were determined as of March 31, 2004.

The following table presents certain comparative historical per share data regarding the net income (loss) and book values of each of STATS and ChipPAC and unaudited combined pro forma per share data after giving effect to the merger as a purchase of ChipPAC by STATS assuming the merger had been consummated at the beginning of the period presented below. The following data assumes 0.87 STATS ADSs will be issued in exchange for each share of ChipPAC Class A common stock in connection with the merger and the substitution of ChipPAC options based upon the same exchange ratio. This data has been derived from and should be read in conjunction with the summary historical financial data, summary unaudited pro forma condensed combined consolidated financial information and the separate audited financial statements and related notes thereto of STATS and ChipPAC, included or incorporated by reference into this document. The unaudited pro forma per share data is presented for informational purposes only and is not intended to represent or be indicative of the consolidated results of operations or financial condition of STATS that would have been reported had the merger been completed as of the dates presented, and should not be taken as representative of future consolidated results of operations or financial condition of STATS. Neither STATS nor ChipPAC paid any dividends in the twelve months ended December 31, 2003 or in the three months ended March 31, 2004.

STATS ordinary shares are listed on the Singapore Exchange under the symbol “ST Assembly” and the STATS ADSs are quoted on the Nasdaq National Market under the symbol “STTS”. Shares of ChipPAC Class A common stock are quoted on the Nasdaq National Market under the symbol “CHPC”. The following table sets forth, for the calendar quarters indicated, based on published financial sources, the high and low closing prices per STATS ordinary share as reported by the Singapore Exchange and the high and low closing prices of STATS ADSs and ChipPAC Class A common stock as reported on the Nasdaq National Market. Neither STATS nor ChipPAC has paid any cash dividends on the STATS ordinary shares, STATS ADSs or ChipPAC Class A common stock, as the case may be, to date.

The following table shows the high and low prices per STATS ordinary share as reported on the Singapore Exchange and the high and low prices per STATS ADS and per share of ChipPAC Class A common stock, each as reported on the Nasdaq National Market on (i) February 9, 2004, the last full trading day preceding public announcement that ChipPAC and STATS had entered into the merger agreement and (ii) June 30, 2004, the last full trading day for which high and low prices were available at the time of the printing of this document.

The table also includes the equivalent high and low price per share of ChipPAC Class A common stock on those dates. This equivalent high and low price per share reflects the fluctuating value of the STATS ADSs that ChipPAC stockholders would receive in exchange for each share of ChipPAC Class A common stock if the merger was completed on either of these dates, applying the exchange ratio of 0.87 STATS ADSs for each share of ChipPAC Class A common stock.

The above table shows only historical comparisons. These comparisons may not provide meaningful information to STATS shareholders in determining whether to approve the issuance of STATS ordinary shares in

connection with the merger or the other matters related to the merger or to ChipPAC stockholders in determining whether to approve and adopt the merger agreement and approve the merger. STATS and ChipPAC shareholders are urged to obtain current market quotations for STATS ordinary shares, STATS ADSs and ChipPAC Class A common stock and to review carefully the other information contained in this document or incorporated by reference into this document in considering whether to approve the proposals contained in this document. See “Where You Can Find More Information” on page 181.

STATS is a public limited company organized under the laws of the Republic of Singapore. Several of STATS’ directors and officers and experts named in this document are nonresidents of the United States, and a significant portion of the assets of STATS and these persons are located outside the United States. As a result, it may not be possible for investors to effect service of process within the United States upon these persons or to enforce, in courts outside the United States, judgments against such persons obtained in United States courts or predicated upon the civil liability provisions of the laws of the United States, including the federal securities laws. Furthermore, since a substantial portion of the assets of STATS are located outside the United States, any judgment obtained in the United States against STATS may not be collectible within the United States. STATS has been advised that judgments of U.S. courts based on the civil liability provisions of the federal securities laws of the United States are not enforceable in Singapore courts. STATS has also been advised that there is doubt as to whether Singapore courts will enter judgments in original actions brought in Singapore courts based solely upon the civil liability provisions of the U.S. securities laws.

Shareholders of STATS and ChipPAC should consider the risks described below relating to the merger, the combined company and the ownership of STATS ADSs before deciding how to vote at their respective shareholders meetings. By voting in favor of the merger and related matters, current ChipPAC stockholders will be choosing to invest in STATS ADSs, and current STATS shareholders will be accepting dilution of their ownership interest in STATS and accepting that STATS will become subject to ChipPAC’s liabilities.

An investment in STATS ADSs involves a high degree of risk. In deciding whether to vote in favor of the merger, STATS and ChipPAC shareholders should consider all of the information that is included in this document and its annexes and all of the information that is included in the documents incorporated by reference. See “Where You Can Find More Information” beginning on page 181.

The market value of STATS ADSs issued in the merger will depend upon their market price at the time of the merger, and no adjustment to the exchange ratio will be made as a result of changes in the market price of STATS ordinary shares or STATS ADSs.

Upon completion of the merger, each share of ChipPAC Class A common stock will be exchanged for 0.87 STATS ADSs. The exchange ratio is fixed and will not be adjusted for changes in the market price of either shares of ChipPAC Class A common stock, STATS ordinary shares or STATS ADSs. As a result, the specific dollar value of STATS ADSs that ChipPAC stockholders will receive and that STATS shareholders will retain upon completion of the merger will depend upon the market value of STATS ADSs when the merger is completed, and may increase or decrease from the date a STATS or ChipPAC shareholder submits a proxy or the time of the shareholders meetings of STATS and ChipPAC. The market prices of STATS ordinary shares, STATS ADSs and shares of ChipPAC Class A common stock fluctuate based on general market and economic conditions, STATS’ and ChipPAC’s business and other factors as discussed in this document, and have experienced significant volatility. No predictions or assurances can be made as to the market price of STATS ordinary shares or STATS ADSs at any time before or after the completion of the merger and, therefore, the STATS ADSs that ChipPAC stockholders will receive in the merger cannot be valued with any degree of certainty.

Failure to receive the private letter ruling from the IRS or an opinion of counsel may delay or prevent the merger.

A condition to closing the merger is receipt by STATS and ChipPAC of the private letter ruling from the IRS or an opinion from a nationally recognized law firm, which private letter ruling or opinion must not have been withdrawn or modified in any material respect prior to the merger, that the exchange of ChipPAC Class A common stock for STATS ADSs in the merger will not result in the recognition of gain under Section 367 of the Internal Revenue Code. STATS and ChipPAC have submitted their request to the IRS for the private letter ruling. In the event that neither the private letter ruling nor the opinions can be obtained, the merger agreement may be terminated by either of STATS or ChipPAC. There can be no assurance that the IRS will issue the private letter ruling prior to the STATS extraordinary general meeting and the ChipPAC special meeting, if at all. If the IRS does not issue the private letter ruling in a timely manner, or advises STATS and ChipPAC that it will not issue the private letter ruling, it is unlikely that nationally recognized law firms would be able to give STATS and ChipPAC opinions in a timely manner, if at all, because under currently applicable Treasury regulations the exchange of ChipPAC Class A common stock for STATS ADSs in the merger would likely result in the recognition of gain under Section 367 of the Internal Revenue Code unless the IRS issues the requested private letter ruling. Consequently, consummation of the merger may be materially delayed and/or the merger agreement may be terminated even if all other conditions to closing have been satisfied or waived, including the requisite STATS shareholder approvals and ChipPAC stockholder approvals.

Any delay of the consummation of the merger could prevent the combined company from realizing the expected benefits of the merger and could materially harm its business, financial results and prospects. In the event that neither the private letter ruling nor the opinion can be obtained, the merger agreement may be terminated.

The combined company may face challenges in integrating ChipPAC with STATS and, as a result, may not realize the expected benefits of the merger.

The combined company may not be successful in integrating the businesses of STATS and ChipPAC. Integrating the two companies’ operations and personnel will be a complex process. The integration may not be completed rapidly and may not achieve the anticipated benefits of the merger. The successful integration of the two companies’ businesses will require, among other things, the following:

The successful integration of the two companies will involve considerable risks and may not be successful. These risks include:

The combined company may not succeed in addressing these risks or any other problems encountered in connection with the merger. The diversion of the attention of management and any difficulties encountered in the process of combining STATS and ChipPAC could cause the disruption of, or a loss of momentum in, the activities of the combined company’s business. Further, the process of combining ChipPAC’s business with STATS’ business could negatively affect employee morale and STATS’ ability to retain some key STATS and ChipPAC employees after the merger. If the anticipated benefits of the merger are not realized or the combined company is unsuccessful in addressing the risks related to the integration, the combined company’s business, financial condition and results of operations may be negatively impacted.

Some of the directors and officers of STATS and ChipPAC may have interests in the merger that are different from, in addition to or conflict with those of other shareholders of STATS and/or stockholders of ChipPAC and that may influence them to support the approval of the merger.

Some of the directors and officers of STATS and ChipPAC participate in arrangements that provide them with interests in the merger that are different from the other shareholders of STATS and/or ChipPAC. These interests, which may influence these individuals to support the merger and the other transactions contemplated by the merger agreement, include the following:

In addition, the surviving corporation in the merger will indemnify each present and former ChipPAC officer and director against liabilities arising out of such person’s services as an officer or director of ChipPAC and will maintain directors and officers liability insurance to cover any such liabilities for the next six years.

The interests are more fully described in the section entitled “The Merger—Interests of certain persons in the merger and the related transactions” beginning on page 87.

Neither the combined company nor ChipPAC may have the ability to raise the funds necessary to finance any change of control offer required to be made in connection with the merger, which would adversely affect the combined company’s liquidity.

The proposed merger will cause a change of control under the ChipPAC senior subordinated notes indenture and may constitute a change of control under the ChipPAC 8% convertible subordinated notes indenture. If the merger is consummated, the combined company or ChipPAC will be required to offer to buy back the $165 million principal amount of outstanding ChipPAC senior subordinated notes for a price equal to 101% of the principal amount of the notes, plus any accrued and unpaid interest to the date of the repurchase and may be required to offer to buy back the $50 million principal amount of outstanding ChipPAC 8% convertible subordinated notes for a price equal to the principal amount of the notes, plus any accrued and unpaid interest to the date of repurchase. If the holders of the ChipPAC senior subordinated notes and the ChipPAC 8% convertible subordinated notes choose to exercise such repurchase rights, the combined company or ChipPAC could be required to repurchase up to $215 million in principal amount of indebtedness. STATS and ChipPAC currently expect to finance any required repurchase of indebtedness transaction expenses and operating cash requirements from cash on hand, operating cash flow and short term borrowings. Neither the combined company nor ChipPAC can assure you that there will be sufficient funds available for it to make any required repurchase of the ChipPAC senior subordinated notes or the ChipPAC 8% convertible subordinated notes upon the change of control. Even if such funds were available, any repurchase of the ChipPAC senior subordinated notes or the ChipPAC 8% convertible subordinated notes would adversely affect the combined company’s liquidity and may adversely affect the combined company’s business, financial condition and results of operations. The combined company may also seek to redeem or refinance outstanding ChipPAC indebtedness following the completion of the merger.

Whether or not the merger is completed, the announcement of the proposed merger may cause disruptions in the business of STATS and ChipPAC, which could have material adverse effects on each company’s business and operations.

Whether or not the merger is completed, the customers, suppliers or other strategic partners of STATS and ChipPAC, in response to the announcement of the merger, may terminate or cancel their existing relationships with STATS or ChipPAC, or delay or defer decisions to enter into or to renew those arrangements, which could have a material adverse effect on the business of each company and, if the merger is completed, the business of the combined company. Similarly, current and prospective STATS and ChipPAC employees may experience uncertainty about their future roles with the combined company, which may adversely affect the ability of the combined company to attract and retain key management, sales, marketing and technical personnel.

STATS and ChipPAC each expect to incur significant transaction costs in connection with the merger, which could adversely affect the financial results of the combined company.

STATS and ChipPAC expect to incur transaction costs of approximately $36.0 million in connection with the merger. If the benefits of the merger do not exceed the associated costs, including costs associated with integrating the two companies and the dilution to STATS shareholders resulting from the issuance of the STATS ADSs issued in connection with the merger, the combined company’s financial results, including earnings per ordinary share and per ADS, could be materially harmed.

The market price of STATS ordinary shares and STATS ADSs may decline as a result of the merger.

The market price of STATS ordinary shares and STATS ADSs may decline as a result of the merger for a number of reasons, including if:

Neither STATS nor ChipPAC may be able to enter into a merger or business combination with another party at a favorable price because of restrictions in the merger agreement.

Provisions in the merger agreement prohibit each of STATS and ChipPAC, subject to certain exceptions, from soliciting, initiating, encouraging or entering into certain other transactions, such as a merger, sale of assets or other business combination outside the ordinary course of business, with any other third parties until the earlier of the consummation of the merger and the termination of the merger agreement. These provisions may discourage other companies from proposing transactions that may be favorable to STATS or ChipPAC and their respective shareholders. As a result, if the merger is not consummated, the parties may be at a disadvantage compared to their competitors.

Charges to earnings resulting from the application of the purchase method of accounting may adversely affect the market value of STATS ordinary shares and STATS ADSs following the merger.

In accordance with United States generally accepted accounting principles, the combined company will account for the merger using the purchase method of accounting, which may result in charges to earnings that could have a material adverse effect on the market value of STATS ordinary shares and STATS ADSs following completion of the merger. Under purchase accounting, STATS will record the market value of the STATS ADSs issued in connection with the merger, the fair market value of the options to purchase ChipPAC Class A common stock that will be substituted with options to purchase STATS ordinary shares and the amount of direct transaction costs, as the cost of acquiring the business of ChipPAC. The combined company will allocate these total costs to ChipPAC’s net tangible assets, amortizable intangible assets and, if any, intangible assets with indefinite lives and in-process research and development, based on their fair values as of the date of completion of the merger, and record the excess of the purchase price over those fair values as goodwill. The portion of the estimated purchase price allocated to in-process research and development, if any, will be expensed by the combined company in the quarter in which the merger is completed. The combined company will incur additional depreciation and amortization expense over the useful lives of certain of the net tangible and amortizable intangible assets acquired in connection with the merger. In addition, to the extent the value of these assets, including goodwill, becomes impaired, the combined company may be required to incur material charges relating to the impairment of those assets. These depreciation, amortization, in-process research and development and potential impairment charges will decrease the net income of the combined company in the foreseeable future, which could have a material impact on the combined company’s results of operations and the market value of STATS ordinary shares and STATS ADSs following the merger.

In addition, the unaudited pro forma condensed combined consolidated financial statements included in this document are based on STATS management’s preliminary estimates of, and good faith assumptions regarding,

the adjustments arising from the proposed merger at the time of the filing of this document. The pro forma adjustments are based upon the limited information currently made available to STATS by ChipPAC for purposes of conducting a valuation of ChipPAC’s assets and liabilities. Not all information required to complete such a valuation is currently available to STATS, due to, among other things, regulatory restrictions and other considerations regarding the sharing of certain information between possible competitors prior to the consummation of the merger, and as additional information becomes available to STATS, the actual allocation of the merger consideration to the ChipPAC assets acquired and liabilities assumed upon the consummation of the merger could differ materially from current estimates. If the actual allocation results in charges that decrease the net income of the combined company, the market value of STATS ordinary shares and STATS ADSs following the merger may be negatively impacted.

Failure to receive necessary governmental consents and approvals or the imposition of restrictions or conditions by governmental authorities may prevent or delay consummation of the merger and may limit the expected benefits of the merger.

The obligations of STATS and ChipPAC to consummate the proposed merger are subject to the satisfaction or waiver of a number of closing conditions including, among other things, receipt of all necessary governmental consents and approvals. In particular, the merger is subject to review by the Antitrust Division and the Federal Trade Commission under the Hart-Scott-Rodino Act. STATS and ChipPAC filed their respective Hart-Scott-Rodino forms on March 9, 2004 and received early termination of the waiting period effective March 19, 2004.

During or after the statutory waiting periods, and even after the completion of the merger, governmental authorities could seek to block or challenge the merger as they deem necessary or desirable in the public interest. The governmental authorities also may impose restrictions or conditions on the merger that may seriously harm the combined company if the merger is completed. These conditions could include a complete or partial license, divestiture, spin-off or the holding separate of assets or businesses. In addition, in some jurisdictions, a competitor, customer or other third party could initiate a private action under the antitrust laws challenging or seeking to enjoin the merger, before or after it is completed. STATS, ChipPAC or the combined company may not prevail, or may incur significant costs, in defending or settling any action under such antitrust laws.

If the combined company is unable to take advantage of opportunities to market and sell STATS’ and ChipPAC’s products and services to the other’s traditional customers, the combined company may not realize some of the expected benefits of the merger.

Prior to the merger, STATS and ChipPAC have each maintained separate and distinct customer bases and business partners specific to their respective businesses. Following the merger, the combined company expects to take advantage of the customer bases of the formerly separate businesses in order to promote and sell the products and services of one company to the traditional customers and business partners of the other company. In the event that the traditional customers and business partners of either STATS or ChipPAC are not receptive to the products and services of the other, the combined company may not realize some of the expected benefits of the merger, and the business of the combined company may be harmed.

STATS and ChipPAC may lose key personnel, customers and business partners due to uncertainties associated with the merger.

Current and prospective employees, customers and business partners of STATS and ChipPAC may experience uncertainty about their future relationship with the combined company. Such uncertainty may adversely affect the combined company’s ability to attract and retain key management, sales, marketing and technical personnel. Current and prospective customers and business partners may, in response to the announcement or consummation of the merger, delay or cancel purchasing decisions. Any delay in, or cancellation of, purchasing decisions could adversely affect the business of the combined company.

In determining whether to approve the merger agreement, the merger and the other matters related to the merger, shareholders of STATS and ChipPAC should read carefully the risks below which relate to STATS’ and ChipPAC’s current business and which will also apply to the business of the combined company following the merger.

Failure to complete the merger could negatively affect the market price of STATS and ChipPAC securities, as well as adversely affect their financial results.

The obligations of STATS and ChipPAC to consummate the proposed merger are subject to the satisfaction or waiver of a number of closing conditions, including receipt of the private letter ruling from the IRS or opinions from nationally recognized law firms relating to the U.S. federal income tax treatment of the merger for ChipPAC stockholders and shareholder approvals. If the merger is not consummated for any reason, STATS and ChipPAC will be subject to a number of material risks, including:

If STATS or ChipPAC is unsuccessful in addressing these risks, their respective business, financial condition and results of operations may be negatively impacted.

STATS and ChipPAC each have experienced substantial losses in the past and the combined company may continue to do so in the future.

STATS achieved operating income of $0.5 million in 2003, but suffered net losses of $1.7 million. Similarly, ChipPAC achieved operating income of $0.4 million in 2003, but suffered net losses of $28.8 million. Although the results of operations for both companies improved in 2003 and during the first quarter of 2004 compared to the prior year and the first quarter of 2003, respectively, no assurance can be made that the combined company will not continue to incur operating losses and net losses in the future due to a variety of factors, including if the semiconductor industry does not recover from the downturn as currently expected or makes only a partial recovery.

Downturns in the semiconductor industry have adversely affected STATS’ and ChipPAC’s operating results, and may continue to adversely affect the combined company’s operating results.

The results from operations of STATS and ChipPAC have been, and of the combined company’s will be, significantly affected by conditions in the semiconductor industry. The market for semiconductors is characterized by:

In addition, the semiconductor industry is cyclical and, at various times, has experienced significant downturns because of production over-capacity and reduced unit demand causing rapid erosion of average selling prices and low capacity utilization. If demand for semiconductor capacity does not keep pace with the growth of supply, or further declines, the combined company’s business would be subject to more intense competition and its results of operations may suffer as a result of the resulting downward pricing pressure and capacity underutilization. The industry began experiencing such a downturn in the fourth quarter of 2000 which continued through 2001 and 2002, with a significant recovery only occurring in 2003, with 18.3% growth in 2003, according to data released by the Semiconductor Industry Association. No assurances can be made that the current recovery or uptrend will continue. If there is any future downturn in the semiconductor industry, the combined company’s business, financial condition and results of operations are likely to be materially adversely affected.

If the combined company is unable to increase its capacity utilization rates, the combined company’s profitability will be adversely affected.

As a result of the capital intensive nature of STATS’ and ChipPAC’s business, the combined company’s operations will be characterized by high fixed costs. Consequently, high capacity utilization will allow the combined company to maintain higher gross margins because it allows the combined company to allocate fixed costs over a greater number of units tested and assembled. Insufficient utilization of installed capacity can have a material adverse effect on the combined company’s profitability. In 2001, STATS’ and ChipPAC’s capacity utilization rates declined substantially from prior levels, primarily as a result of a decrease in demand for their test and assembly services resulting from a downturn in the overall semiconductor industry, particularly for communications applications. Due to the high level of fixed costs, STATS and ChipPAC suffered substantial net losses in 2001 and 2002. While capacity utilization rates increased in 2002 and 2003, net losses continued in 2003.

The combined company’s ability to restore or increase its profitability and enhance its gross margins will continue to be dependent, in large part, upon its ability to achieve high capacity utilization rates. Capacity utilization rates may be affected by a number of factors and circumstances, including:

The combined company cannot make any assurances that its capacity utilization rates will return to the former high levels of STATS or ChipPAC or that the combined company will not be materially adversely affected by a continued decline or future declines in the semiconductor industry, declines in industries that purchase semiconductors or other factors. Any inability on the part of the combined company to increase its capacity utilization rates could have a material adverse effect on the combined company’s business, financial condition and results of operations.

A decrease in demand for communications equipment and personal computers would significantly decrease the demand for the combined company’s services.

Substantially all of STATS’ and ChipPAC’s net revenues were derived from customers who use STATS’ or ChipPAC’s test or assembly services for semiconductors used in communications equipment and personal computers. In 2002 and 2003, 84.6% and 88.2%, respectively, of STATS’ net revenues, and 57.5% and 61.0%, respectively, of ChipPAC’s net revenues, were derived from testing and assembly of semiconductors used in such applications. Any significant decrease in the demand for communications equipment or personal computers may decrease the demand for the combined company’s services and could seriously harm STATS and the combined company. In addition, the declining average selling price of communications equipment and personal computers places significant pressure on the prices of the components that are used in this equipment. If the average selling prices of communications equipment and personal computers continue to decrease, the pricing pressure on services provided by STATS, ChipPAC or the combined company may reduce our net revenues and therefore significantly reduce the combined company’s gross profit margin.

STATS’ and ChipPAC’s results fluctuate, and the combined company’s operating results may fluctuate, from quarter to quarter, which may make it difficult to predict the future performance of the combined company and could cause volatility in the market price of STATS ordinary shares and STATS ADSs following the merger.

STATS’ and ChipPAC’s operating results have fluctuated, and the combined company’s operating results may continue to fluctuate, substantially from quarter to quarter due to a wide variety of factors, including:

As a result of all of these factors, STATS and ChipPAC believe that period-to-period comparisons of their respective operating results may not be meaningful, and that such comparisons to predict the combined company’s future performance may not be meaningful. Unfavorable changes in any of the above factors may adversely affect the combined company’s business, financial condition and results of operations. In addition, such unfavorable changes could cause volatility in the price of STATS ordinary shares and STATS ADSs.

The combined company’s profitability will be affected by average selling prices of test and assembly services that have experienced pricing pressures and tend to decline.

Decreases in the average selling prices of test and assembly services can have a material adverse effect on the combined company’s profitability. The average selling prices of test and assembly services have declined historically, with assembly services in particular experiencing severe pricing pressure. This pricing pressure for test and assembly services is likely to continue. The combined company’s ability to maintain or increase its profitability will continue to be dependent, in large part, upon its ability to offset decreases in average selling prices by improving production efficiency, increasing unit volumes tested or assembled, or by shifting to higher margin test and assembly services. If the combined company is unable to do so, its business, financial condition and results of operations could be materially adversely affected.

The combined company will depend on a small number of customers for a significant portion of its revenues and any decrease in sales to any of them could adversely affect its business and results of operations.

The combined company will be dependent on a small group of customers for substantially all of their respective net revenues. STATS’ ten largest customers accounted for 85.6%, 79.8% and 78.8% of STATS’ net revenues in 2001, 2002 and 2003, respectively. In the year ended December 31, 2003, STATS’ three largest customers, Analog Devices, Inc., Broadcom Corporation and Marvell Technology Group Ltd., each represented in excess of 10% of STATS’ net revenues and in the aggregate represented 57.2% of STATS’ net revenues. ChipPAC’s ten largest customers accounted for 89.1%, 88.6% and 79.1% of ChipPAC’s net revenues in 2001, 2002 and 2003, respectively. In the year ended December 31, 2003, ChipPAC’s four largest customers, Intel Corporation, Intersil, LSI Logic Corporation and nVidia Corporation, each represented in excess of 10% of ChipPAC’s net revenues and in the aggregate represented approximately 50% of ChipPAC’s net revenues.

Although no one customer is expected to account for more than 15% of the combined company’s revenue after the merger, the combined company anticipates that for the foreseeable future its ten largest customers will continue to account for a significant portion of its net revenues. The ability of the combined company to retain these customers, as well as other customers and to add new customers is important to the ongoing success of the combined company. The loss of one or more key customers, or reduced demand from any key customers, could have a material adverse effect on the combined company’s business, financial condition and results of operations.

Decisions by IDM customers to curtail outsourcing may adversely affect the combined company.

Historically, STATS and ChipPAC have been dependent on the trend in outsourcing of test and assembly services by IDMs. IDM customers continually evaluate the outsourced services against their own in-house test and assembly services. As a result, at any time, IDMs may decide to shift some or all of their outsourced test and assembly services to internally sourced capacity. Any such shift or a slowdown in this trend of outsourcing test and assembly services is likely to adversely affect the combined company’s business, financial condition and results of operations.

In a downturn in the semiconductor industry, IDMs may respond by shifting some outsourced test and assembly services to internally serviced capacity on a short term basis. This would have a material adverse effect on the combined company’s business, financial condition and results of operations, especially during a prolonged industry downturn.

The combined company may not be able to develop or access leading technology that may affect its ability to compete effectively.

The semiconductor test and assembly markets are characterized by rapid technological change and increasing complexity. The combined company must be able to offer its customers test and assembly services based upon the most advanced technology. This requirement could result in significant research and development expenditures and capital expenditures in the future. The combined company will periodically review its

equipment for obsolescence and impairment. If it is determined that, due to technology advances, reduced demand in certain end markets or otherwise, the anticipated future usage of any equipment has been diminished, the combined company will write down such equipment. In 2001 and 2002, STATS wrote down $26.9 million and $15.4 million of equipment, respectively, and made no write downs in 2003. In 2003, ChipPAC wrote down $11.7 million of impaired assets.

If the combined company fails to develop advanced test and assembly services or to access those developed by others in a timely manner, it could lose customers or miss potential customers demanding these advanced services. Developing new technology may result in longer sales cycles and product implementations, which may cause revenue and operating income to fluctuate and fail to meet expectations. Also, the combined company would miss the opportunity to benefit from the higher average selling prices that are derived from newer and emerging test and assembly services. In addition, the choice of test equipment will be important to the combined company because obtaining the wrong test equipment or failing to understand market requirements will make the combined company less competitive and will lower its asset utilization. In order to remain competitive, the combined company must be able to upgrade or migrate its test equipment to respond to changing technological requirements.

The testing and assembly process is complex and the combined company’s production yields and customer relationships may suffer from defects or malfunctions in its testing equipment or defective packages and the introduction of new packages.

Semiconductor testing and assembly are complex processes that require significant technological and process expertise. Semiconductor testing involves sophisticated testing equipment and computer software. STATS and ChipPAC develop computer software that is used to test their respective customers’ semiconductors. STATS and ChipPAC also develop conversion software programs which enable the companies to test semiconductors on different types of testers. Similar to most software programs, these software programs are complex and may contain programming errors or “bugs”. In addition, the testing process is subject to operator error by employees who operate testing equipment and related software. Any significant defect in the testing or conversion software, malfunction in the testing equipment or operator error could reduce the combined company’s production yields, damage customer relationships and materially harm the combined company’s business.

The assembly process is complex and involves a number of precise steps. Defective packages primarily result from:

These and other factors have, from time to time, contributed to lower production yields. They may do so in the future, particularly as the combined company expands its capacity or changes its processing steps. In addition, to be competitive, the combined company must continue to expand its offering of packages. The production yields on new packages typically are significantly lower than production yields on more established packages.

The failure to maintain high standards or acceptable production yields, if significant and prolonged, could result in lost customers, increased costs of production, delays, substantial amounts of returned goods and claims by customers relating thereto. Any of these problems could have a material adverse effect on the combined company’s business, financial condition and results of operations.

If the combined company is unable to obtain testing or assembly equipment in a timely manner and on reasonably favorable terms and prices, the combined company may be unable to meet customer demands and its revenue may decline.

The semiconductor test and assembly business is capital intensive and requires investment in expensive capital equipment manufactured by a limited number of suppliers, which are located principally in the United States, Singapore, Europe, Korea, and Japan. The market for capital equipment used in semiconductor testing is characterized, from time to time, by intense demand, limited supply and long delivery cycles. The combined company’s operations and expansion plans are highly dependent upon its ability to obtain a significant amount of capital equipment from a limited number of suppliers. If the combined company is unable to obtain certain equipment, such as testers and wire bonders, in a timely manner, it may be unable to fulfill its customers’ demand, which would negatively impact the combined company’s business, financial condition and results of operations.

Generally, neither STATS nor ChipPAC have binding supply agreements with any of their respective suppliers and the companies acquire equipment on a purchase order basis, which may expose the combined company to substantial risks. For example, increased levels of demand for the type of capital equipment required in their respective businesses may cause an increase in the price of such equipment and may lengthen delivery cycles, which could have a material adverse effect on the combined company’s business, financial condition and results of operations. In addition, adverse fluctuations in foreign currency exchange rates, particularly the Japanese yen, could result in increased prices for certain equipment purchased by the combined company, which could have a material adverse effect on the combined company’s business, financial condition and results of operations.

The combined company is expected to incur significant capital expenditures in the future and therefore may require additional financing in the future which may not be available on acceptable terms, if at all.

The combined company’s capital expenditures will be largely driven by the demand for its services. The combined company will not be able to accurately estimate its capital expenditure beyond the upcoming quarter. The combined company’s pro forma capital expenditures increased from $213.6 million in 2002 to $362.6 million in 2003, primarily as a result of an increase in demand for services. In 2004, the combined company expects that its capital expenditures will be between $300 million and $390 million. To grow its business, the combined company will need to increase its test and assembly capacity, as well as replace existing equipment from time to time. This will require substantial capital expenditures for additional equipment and further expenditures to recruit and train new employees. These expenditures will likely be made in advance of increased sales. No assurances can be made that the combined company’s net revenues will increase after these expenditures. The combined company’s failure to increase its net revenues after these expenditures could have a material adverse effect on the combined company’s business, financial condition and results of operations.

The combined company may need to obtain additional debt or equity financing to fund its capital expenditures. Additional equity financing may result in dilution to the holders of STATS ordinary shares and STATS ADSs. Additional debt financing may be required which, if obtained, may:

No assurances can be made that the combined company will be able to obtain the additional financing on terms that are acceptable to it or at all.

STATS and ChipPAC have entered into a number of financial arrangements that will impose limitations on the combined company’s actions which may limit its ability to maintain and grow its business.

The terms of the STATS convertible notes, the STATS Medium Term Notes program (the STATS MTN program), the ChipPAC convertible subordinated notes and the ChipPAC senior subordinated notes contain restrictions on the respective companies’ ability to, among other things:

These limitations will be applicable to the combined company after the merger. As a result of these limitations, the combined company may encounter difficulties obtaining the required consents from existing lenders to conduct its business, in particular, to obtain the necessary financing to maintain or grow its business, on a timely basis or at all. This could have a material adverse effect on the combined company’s business, financial condition and results of operations.

The combined company generally will not have any long-term supply contracts with its raw materials suppliers and may not be able to obtain the raw materials required for its business, which could have a material adverse effect on its business.

STATS and ChipPAC obtain the materials they need for their assembly services from outside suppliers. The companies purchase all of their materials on a purchase order basis. Neither STATS nor ChipPAC generally have entered into long-term contracts with their suppliers. If the combined company cannot obtain sufficient quantities of materials at reasonable prices or if it is not able to pass on higher materials costs to its customers, this could have a material adverse effect on the combined company’s business, financial condition and results of operations.

The combined company may not be successful in its acquisitions of and investments in other companies and businesses.

As part of its growth strategy, from time to time, STATS and ChipPAC made, and the combined company may make, acquisitions of or investments in other companies or businesses. For example, in 2003, STATS set up a new manufacturing facility in Shanghai, China as a first step of its strategic plan to establish a significant manufacturing presences in China to service its existing international customers, as well as engage the indigenous Chinese foundries and design houses. In 2001, STATS acquired a majority interest in Winstek Semiconductor Corporation (Winstek) to enhance its positions in the Taiwanese market. The merger described in this document is another example of this growth strategy.

The success of the merger and any future acquisitions and investments depends on a number of factors, including:

If the combined company is unsuccessful in its acquisitions and investments, its financial condition may be materially adversely affected.

The combined company may not be able to compete successfully in its industry.

The independent semiconductor test and assembly service industry is very competitive and diverse and will require that the combined company be capable of testing increasingly complex semiconductors, as well as bringing the most technologically advanced packages to market as quickly as its competitors. The industry comprises both large multi-national companies and small niche market competitors. STATS and ChipPAC face, and the combined company will face, substantial competition from a number of competitors that are much larger in size. These competitors include, among others, Advanced Semiconductor Engineering, Inc., Amkor Technology, Inc., ASE Test Limited, ASAT Holdings Limited and Siliconware Precision Industries Co., Ltd. Their facilities are primarily located in Asia.

Each of these companies has significant manufacturing capacity, financial resources, research and development operations, marketing and other capabilities and has been in operation for some time. Such companies have also established relationships with many of STATS’ and ChipPAC’s current or the combined company’s potential customers. Some of these competitors have established testing facilities in North America and may commence independent testing operations in Asia. These activities would compete directly with the combined company’s activities.

STATS and ChipPAC also face, and the combined company will face, competition from the internal capabilities and capacity of many of their current and potential IDM customers. Many IDMs have greater financial, technical and other resources than STATS, ChipPAC or the combined company and may rely on internal sources for test and assembly services for a number of reasons, including due to:

No assurance can be made that the combined company will be able to compete successfully in the future against its existing or potential competitors or that its customers will not rely on internal sources for test and assembly services, or that the combined company’s business, financial condition and results of operations will not be adversely affected by such increased competition.

STATS’ and ChipPAC’s intellectual property will be important to the ability of the combined company to succeed in its business, but may be difficult to obtain and protect.

The combined company’s ability to compete successfully and achieve future growth in net revenues will depend, in part, on its ability to develop and to protect STATS’, ChipPAC’s and its intellectual property and the intellectual property of its customers. The companies seek, and the combined company will seek, to protect

proprietary information and know-how through patents, the use of confidentiality and non-disclosure agreements and limited access to and distribution of proprietary information. As of February 15, 2004, STATS had six issued patents in Singapore, over 35 issued patents in the United States, over 65 pending patent applications in Singapore and over 35 pending patent applications in the United States. As of March 8, 2004, ChipPAC had 14 issued patents in Korea, 3 issued patents in the United States, 47 pending patent applications in Korea and 31 pending patent applications in the United States.

No assurance can be made that any of STATS’ or ChipPAC’s filed applications for patents will be granted, or, if granted, will not be challenged, invalidated or circumvented or will offer the combined company any meaningful protection. Further, no assurance can be made that the Asian countries in which the combined company will market its products and services will protect the combined company’s intellectual property rights to the same extent as the United States. In particular, historically, China, Taiwan, Korea and certain other countries in Southeast Asia in general have not protected intellectual property to the same extent as the United States. Additionally, no assurance can be made that the competitors of STATS, ChipPAC or the combined company will not develop, patent or gain access to similar know-how and technology, or reverse engineer the assembly services of STATS, ChipPAC or the combined company, or that any confidentiality and non-disclosure agreements upon which STATS, ChipPAC or the combined company relies to protect their trade secrets and other proprietary information will be adequate protection. The occurrence of any such events could have a material adverse effect on the combined company’s business, financial condition and results of operations.

STATS and ChipPAC have licenses to use third-party patents, patent applications and other technology rights, as well as trademark rights, in the operation of their respective businesses. To the extent these licenses are not perpetual and irrevocable, STATS and ChipPAC believe that these licenses are renewable under normal commercial terms upon their expiration. However, the combined company may be unable to utilize the technologies under these licenses if they are not extended or otherwise renewed or if any of these licenses are terminated by the licensor due to STATS’, ChipPAC’s or the combined company’s uncured breach or bankruptcy, as the case may be. Alternatively, if the combined company is able to renew these license arrangements, no assurances can be made that they will be on the same terms as currently exist. Any failure to extend or renew these license arrangements could cause the combined company to incur substantial liabilities and to suspend the packaging services and processes that utilize these technologies.

The combined company may be subject to intellectual property rights disputes, which could have a materially adverse effect on its business.

The combined company’s ability to compete successfully will depend, in part, on its ability to operate without infringing the proprietary rights of others. When STATS, ChipPAC or the combined company becomes aware of the valid intellectual property of others that may pertain to or affect its business, the companies will attempt to either design around such intellectual property, or license, cross-license or otherwise obtain the intellectual property rights that they feel are required. However, the companies have no means of ascertaining what patent applications have been filed in the United States until they are granted or, for certain patent applications, until they are published. In addition, the companies may not be aware of the intellectual property rights of others or be familiar with the laws governing such rights in certain countries in which their products and services are or may be sold. As the number of patents, copyrights and other intellectual property rights in their industry increases, and as the coverage of these rights increases, the combined company may face more frequent patent infringement claims and other intellectual property claims brought by third parties.

In the event that any valid claim is made against STATS, ChipPAC or the combined company, such party could be required to:

It is the nature of the semiconductor industry that, from time to time, STATS, ChipPAC or the combined company may receive communications alleging that such party has infringed the intellectual property rights of others. STATS, ChipPAC or the combined company may also, from time to time, receive from customers requests for indemnification against pending or threatened infringement claims brought against such customers. No assurances can be made that the resolution of any future allegation or request for indemnification will not have a material adverse effect on the combined company’s business or financial condition.

Although the combined company may seek licenses from or enter into agreements with third parties covering the intellectual property that STATS, ChipPAC or the combined company are allegedly infringing, no assurance can be made that any such licenses could be obtained on acceptable terms, if at all. The combined company may also have to commence lawsuits against companies who infringe its intellectual property rights. Such claims could result in substantial costs and diversion of the combined company’s resources.

Should any of the disputes described above occur, the combined company’s business, financial condition and results of operations could be materially adversely affected.

The combined company will be exposed to certain risks as a result of the significant ownership by STS, an indirectly owned subsidiary of the Government of Singapore.

On June 16, 2004, STS, an indirectly owned subsidiary of Temasek Holdings, the principal holding company through which the corporate investments of the Government of Singapore are held, beneficially owned approximately 66.1% of the outstanding STATS ordinary shares. After the merger, STS, and hence the Government of Singapore, will beneficially own approximately 33.0% of the outstanding STATS ordinary shares and the combined company will be exposed to certain risks as a result of the significant ownership by the Government of Singapore. In particular, the interests of STS and the Government of Singapore may sometimes conflict with those of STATS other shareholders. There can be no assurance that in the event of such a conflict, STS or the Government of Singapore will vote its shares in a way that benefits the other shareholders of the combined company.

STS controls STATS and will be a significant shareholder of the combined company, and therefore will have the ability to exercise significant influence over matters requiring the approval of the combined company’s shareholders.

As a result of holding, as of June 16, 2004, approximately 66.1% of the outstanding STATS ordinary shares, STS currently is able to exercise direct control over matters requiring STATS shareholder approval. After the merger, STS will beneficially own approximately 33.0% of the outstanding STATS ordinary shares and STS will have significant influence over matters requiring the approval of the combined company’s shareholders.

Matters that typically will require the approval of the shareholders of the combined company include, among other things:

This concentration of ownership may delay, deter or prevent acts that could result in a change of control of the combined company, which may be against the interests of the other holders of STATS ordinary shares and STATS ADSs.

A change in control of the combined company could result in a breach of certain of its agreements which could have a material adverse effect on the combined company’s financial condition.

The STATS convertible notes and the STATS MTN program provide that noteholders may require STATS to redeem the notes if any person, other than STPL or its affiliates, holds, directly or indirectly, more than 50% of STATS’ issued share capital. Similarly, the ChipPAC convertible subordinated notes and the ChipPAC senior subordinated notes provide that noteholders may require ChipPAC to repurchase the notes upon a change of control, as defined in the respective indentures. See “The Merger—Effect of the merger on the ChipPAC notes” beginning on page 63. After the merger, the combined company will be subject to these covenants.

From time to time, the combined company may agree to similar terms in its financing or other arrangements. If this were to occur, the financial condition of the combined company may be materially adversely affected. This restriction may also limit the ability of the combined company to raise funds through the issuance of equity or equity-linked securities.

The combined company may have conflicts of interest with its affiliates which may not be resolved in favor of the combined company.

In the past, a substantial portion of STATS’ financing, as well as certain amounts of STATS’ net revenues, have come from its affiliates, and STATS has paid a management fee to STPL for certain services. The combined company will continue to have certain contractual and other business relationships and may engage in material transactions with the Government of Singapore, companies within the Singapore Technologies Group (including Chartered Semiconductor Manufacturing Ltd, which is a customer) and EDB Investments Pte Ltd (EDBI). Although all new material related party transactions generally will require the approval of the audit committee of the combined company’s board of directors and in certain circumstances may also require separate approval of a majority of the combined company’s board of directors, circumstances may arise in which the interests of the combined company’s affiliates may conflict with the interests of its other shareholders. In addition, EDBI, STPL and their affiliates make investments in various companies. They have invested in the past, and may invest in the future, in entities that compete with the combined company. For example, affiliates of STPL have investments in United Test & Assembly Center Ltd, a Singapore-based provider of semiconductor assembly and testing services for semiconductor logic/ASIC and memory products. In the context of negotiating commercial arrangements with affiliates, conflicts of interest have arisen in the past and may arise, in this or other contexts, in the future. No assurance can be made that any conflicts of interest will be resolved in favor of the combined company.

The combined company will have a substantial amount of outstanding indebtedness and may require financing to fulfill its obligations under its indebtedness.

As of March 31, 2004, STATS had $361.4 million of long-term debt outstanding, excluding current installments, of which $330.3 million was comprised of STATS convertible notes, compared to $219.4 million of long-term debt outstanding as of March 31, 2003. As of March 31, 2004, ChipPAC had $365.0 million of long-term debt outstanding, of which $200 million was comprised of ChipPAC convertible subordinated notes and $165 million was a guarantee of the ChipPAC senior subordinated notes, compared to $267.9 million of long-term debt outstanding as of March 31, 2003.

In addition, the holders of STATS convertible notes may, in certain circumstances, including a change in control of STATS, as defined in the respective indenture relating to the STATS 1.75% convertible notes and the STATS 4.25% convertible notes, or on March 18, 2005 in respect of the STATS 1.75% convertible notes and on November 7, 2007 in respect of the STATS 4.25% convertible notes, require the combined company to redeem all or a portion of the holders’ STATS convertible notes. Similarly, the holders of the ChipPAC 2.5% convertible subordinated notes due, the ChipPAC 8% convertible subordinated notes and the ChipPAC senior subordinated notes may, in certain circumstances, including a change in control of ChipPAC, as defined in the respective indenture relating to the ChipPAC 2.5% convertible subordinated notes and the ChipPAC 8% convertible subordinated notes, require the combined company to redeem all or a portion of the holders’ notes. The combined company may be required to refinance its debt in order to make such payments. If such an event were to occur, or at maturity of the notes, no assurance can be made that the combined company will have sufficient funds or would be able to arrange financing to make the required purchase or redemption. The combined company may not be able to obtain such financing on terms that are acceptable to it or at all. If the combined company is unable to obtain adequate financing to repurchase or redeem the notes, the combined company will be in default under the terms of the notes.

The combined company will depend on certain key employees and the loss of certain of them could adversely affect its business.

The success of the combined company will depend on the continued service of its key senior management, in particular Mr. Tan Lay Koon, Mr. Han Byung Joon and the chief operating officers of its test and assembly facilities. The combined company will not maintain “key man” life insurance on any of its personnel. The loss of these persons could have a material adverse effect on the combined company’s business, financial condition and results of operations, particularly if it is unable to find, relocate and integrate adequate replacements for any of these persons. Further, in order to develop or grow its business, the combined company will require experienced technical, customer support, sales and management personnel and other skilled employees. The combined company may be unable to attract or retain these persons. This could disrupt its operations or materially adversely affect the success of its business.

STATS’ independent auditors have notified STATS’ audit committee that it considers resource constraints in STATS’ accounting department to be a material weakness in STATS’ internal controls. STATS’ audit committee has requested management to take all action necessary to address this concern promptly and STATS’ management is taking action to address this concern. If STATS does not successfully address this concern, the combined company’s ability to comply with applicable financial reporting requirements on a timely basis could be impaired.

As part of a recent audit process, STATS’ independent auditors, KPMG, notified the STATS audit committee of certain reportable conditions, including its concern that resource constraints in STATS’ accounting department constitute a material weakness of STATS’ internal controls. In light of the complex and changing nature of the reporting environment in which STATS operates (including the significant changes to internal control documentation and reporting requirements resulting from the U.S. Sarbanes-Oxley Act) and the size and complexity of its business, KPMG recommended that STATS significantly enhance its accounting and financial reporting department staffing, including by hiring a Chief Financial Officer who ideally would have experience in the same capacity at a company publicly listed on a U.S. stock exchange and that uses U.S. generally accepted accounting principles (U.S. GAAP), or a partner or senior manager from an audit firm that audited such companies, or by hiring a supporting financial reporting manager or controller with similar experience. KPMG also recommended that STATS establish a corporate level accounting support group, ideally including one or

more U.S. certified public accountants. KPMG’s reports on STATS’ consolidated financial statements did not contain an adverse opinion, a disclaimer of opinion or a qualification or modification as to uncertainty, audit scope or accounting principles. In addition, there have been no disagreements between STATS and KPMG regarding accounting principles or practices, financial statement disclosure or auditing scope or procedures that have not been resolved to the satisfaction of KPMG and KPMG has not reported any instances of fraud. KPMG has not advised STATS that information has come to KPMG’s attention that has made KPMG unwilling to be associated with the historical financial statements. STATS’ audit committee and management have discussed the recommendations with KPMG and STATS intends to take prompt action to address the concern. STATS intends to add resources to its accounting staff, including retaining some of ChipPAC’s financial reporting staff. Prior to receiving the letter from KPMG, STATS had entered into an employment agreement with Mr. Potter, the Acting Chief Financial Officer of ChipPAC, to become Chief Financial Officer of STATS upon completion of the merger. Mr Potter will provide additional accounting resources to the combined company and enhance its U.S. GAAP reporting expertise. KPMG also noted three additional reportable conditions related to STATS’ internal controls and recommended that STATS establish a policy to involve STATS’ accounting department in the review and approval of significant new contracts, that STATS review key manual controls and ensure that their performance is documented, and that STATS review its investment policy and foreign exchange management practices. STATS and the STATS audit committee have discussed each of these reportable conditions and recommendations with KPMG and, in response to KPMG’s recommendations, STATS has amended its contracts policy to require specifically that the accounting department be informed of all contracts upon their agreement or execution, STATS has incorporated additional controls into its inventory counting process, one of its key manual controls, and has explained its investment policy and foreign exchange management practices in regards to retaining a significant portion of its proceeds that it raised from the debt and equity offerings in November 2003 as a natural hedge to fund its Singapore dollar payment requirements and entering into a one-month S$10 million principal amount foreign currency derivative instrument with the objective to increase the interest yield on such funds. See “STATS Proposals at the STATS Extraordinary General Meeting—Resolution 11: Appoint PricewaterhouseCoopers, Singapore as auditors to STATS” on page 135. STATS’ failure to correct its resource constraint or its failure to discover and address any other weakness in its internal controls could impair the combined company’s ability to comply with applicable financial reporting requirements on a timely basis.

The combined company will need a controlled environment for its operations and any prolonged inability to maintain a clean room environment may disrupt its operations and materially adversely affect its business.

STATS’ and ChipPAC’s testing and assembly operations take place in areas where air purity, temperature and humidity are controlled. If the combined company is unable to control its testing or assembly environment, its test or assembly equipment may become nonfunctional or the tested and assembled semiconductors may be defective. If the combined company experiences prolonged interruption in its operations due to problems in the clean room environment, this could have a material adverse effect on the combined company’s business, financial condition and results of operations.

Liabilities and obligations under certain environmental laws and regulations could require the combined company to spend additional funds and could adversely affect the combined company’s financial condition and results of operations.

STATS and ChipPAC are, and the combined company will be, subject to a variety of environmental laws and regulations in the countries in which they have operations, including laws and regulations relating to the use, storage, discharge and disposal of hazardous materials and the chemical by-products of, and waste water discharges from, their testing and assembly processes. STATS and ChipPAC may also be subject to liability under such laws and regulations for the investigation or cleanup of contamination caused by, or other damages associated with, the release of hazardous materials in connection with current or historical operations at their facilities or off-site locations. While STATS and ChipPAC believe that they are currently in material compliance with such laws and regulations, failure to comply with such laws and regulations in the future could subject the combined company to liabilities that may have an adverse effect on the combined company’s financial condition and results of operations. While STATS and ChipPAC believe that they do not face material liabilities associated

with contamination conditions and that in some cases ChipPAC has contractual indemnification agreements with predecessors relating to such conditions, should these predecessors become unable or unwilling to address these conditions, or should other yet unknown conditions be identified in the future that are not subject to such indemnification agreements, the combined company could face environmental liabilities that may have an adverse effect on the combined company’s financial condition and results of operations.

A fire or other calamity at one of its facilities could adversely affect the combined company.

STATS and ChipPAC conduct, and the combined company will conduct, their testing and assembly operations at a limited number of facilities. Significant damage at any of these facilities as a result of a fire or other calamity would have a material adverse effect on the combined company’s business, financial conditions and results of operations. Some of the processes to be utilized by the combined company in its operations place it at risk of fire and other damage. For example, highly flammable gases are used in the preparation of wafers holding semiconductor devices for flip chip assembly. While the combined company will maintain insurance policies covering losses, including losses due to fire, which the combined company considers to be adequate, no assurance can be made that it would be sufficient to cover all of its potential losses. The combined company’s insurance policies cover its buildings, machinery and equipment.

Research and development investments may not yield profitable and commercially viable packages or test services and thus will not necessarily result in increases in revenues for the combined company.

STATS and ChipPAC invest significant resources in their research and development. However, research and development efforts may not yield commercially viable packages or test services. The qualification process for new packages and test services is conducted in various stages which may take one or more years to complete, and during each stage there is a substantial risk that the combined company will have to abandon a potential package or test service which is no longer marketable and in which STATS, ChipPAC or the combined company have invested significant resources. In the event the combined company is able to qualify new packages or test services, a significant amount of time will have elapsed between its investment in new packages or test services and the receipt of any related revenues. In addition, from time to time, customers of STATS and ChipPAC have requested, and customers of the combined company may request, research and development services relating to the development of packages and/or services. These customers generally do not, and may not, reimburse the combined company for its research and development expenses if the developed package or service does not achieve expected levels of demand or utilization.

Significant fluctuations in exchange rates may affect the financial condition and results of operations of the combined company.

STATS’ financial statements are prepared in U.S. dollars. STATS’ net revenues are generally denominated in U.S. dollars and operating expenses are generally incurred in U.S. dollars and Singapore dollars. STATS’ capital expenditures are generally denominated in U.S. dollars, Japanese yen, Singapore dollars and other currencies. In addition, a portion of ChipPAC’s costs are denominated in foreign currencies, including the South Korean Won, the Chinese Renminbi (RMB), the Malaysian Ringgit and the Japanese Yen. As a result, the combined company will be affected by significant fluctuations in foreign currency exchange rates among the U.S. dollar, the Japanese yen, the Singapore dollar and other currencies and the combined company will be affected by fluctuations in foreign currency exchange rates among the foregoing currencies, as well as the South Korean Won, the Chinese RMB and the Malaysian Ringgit.

The ability of the combined company to make further investments in its subsidiaries may be dependent on regulatory approvals.

The combined company’s subsidiaries may require future equity-related financing, and any capital contributions to certain of its subsidiaries, such as Winstek, STATS Shanghai Ltd. or ChipPAC Shanghai

Limited, may require the approval of the relevant authorities in the jurisdiction in which the subsidiary is incorporated. The approvals are required from the investment commissions of the particular jurisdiction and relate to any initial or additional equity investment by foreign entities in local corporations. The combined company may not be able to obtain any such approval in the future in a timely manner or at all.

If the combined company encounters future labor problems, it may fail to deliver its products in a timely manner, which could adversely affect its revenues and profitability.

ChipPAC’s employees at its Ichon, South Korea facility are represented by the ChipPAC Korea Labor Union and are covered by collective bargaining and wage agreements. The wage agreement is renewed every year, and the collective bargaining agreement, which covers basic union activities, working conditions and welfare programs, among other things, is renewed every other year. ChipPAC entered into new wage and collective bargaining agreements with the union in June 2003, which were retroactive to May 1, 2003. As of December 31, 2003, approximately 64% of ChipPAC’s South Korean employees were represented by the ChipPAC Korea Labor Union. In addition, one of ChipPAC’s Chinese subsidiaries experienced labor protests and a two-day work stoppage in July 1998 in connection with proposed workforce reductions. No assurances can be made that issues with the labor union or other employees will be resolved favorably for it in the future, that it will not experience significant work stoppages in future years or that it will not record significant charges related to those work stoppages. In addition, potential efficiency enhancement efforts, including personnel reductions, following ChipPAC’s acquisition of the Malaysian business may create the risk of labor problems in Malaysia or at other facilities.

Because a significant portion of Winstek’s business and operations are located in Taiwan, a severe earthquake could severely disrupt the normal operation of Winstek’s business and adversely affect the combined company’s earnings.

Taiwan is susceptible to earthquakes. For example, on March 31, 2002, Taiwan experienced a severe earthquake that caused significant property damage and loss of life, particularly in central Taiwan. This earthquake damaged production facilities and adversely affected the operations of many companies involved in the semiconductor and other industries. STATS’ 55% owned subsidiary, Winstek, experienced no structural damage to its facilities and no damage to its machinery and equipment as a result of this earthquake. There were, however, interruptions to STATS’ production schedule primarily as a result of power outage caused by the earthquake. The production facilities of many of STATS’ suppliers and customers and providers of complementary semiconductor manufacturing services, including foundries, are located in Taiwan. If STATS’ customers are affected, it could result in a decline in the demand for the combined company’s testing and packaging services. If suppliers and providers of complementary semiconductor manufacturing services are affected, the combined company’s production schedule could be interrupted or delayed. As a result, a major earthquake in Taiwan could severely disrupt the normal operation of business, in particular Winstek’s business, and may have a material adverse effect on the combined company’s financial condition and results of operations.

New laws and regulations, currency devaluation and political instability in foreign countries, particularly in China, Malaysia, South Korea and Taiwan could make it more difficult for the combined company to operate successfully.

For the years ended December 31, 2003, 2002 and 2001, approximately 18.6%, 19.2% and 21.6%, respectively, of the combined company’s pro forma total revenues were generated from markets outside the United States, primarily from customers in Southeast Asia and Europe. In addition, substantially all of the combined company’s test and assembly facilities will be located in China, Malaysia, Singapore, South Korea and Taiwan. The combined company cannot determine if its future operations and earnings will be affected by new laws, new regulations, a volatile political climate, changes in or new interpretations of existing laws or regulations or other consequences of doing business outside the United States, particularly in China, Malaysia,

South Korea and Taiwan. If future operations are negatively affected by these changes, the combined company’s sales or profits may suffer.

The combined company could suffer adverse tax and other financial consequences if U.S. or foreign taxing authorities do not agree with its interpretation of applicable tax laws.

ChipPAC’s corporate structure and operations are based, in part, on interpretations of various tax laws, including withholding tax, and other relevant laws of applicable non-U.S. jurisdictions. In the merger, ChipPAC will become a wholly owned subsidiary of STATS. No assurances can be made that non-U.S. taxing authorities will agree with ChipPAC’s or the combined company’s interpretations or that they will reach the same conclusions. For example, the Korean National Tax Administration (the Korean Tax Administration) has informed ChipPAC that the Korean Tax Administration has made an assessment of approximately $13.4 million against ChipPAC relating to withholding tax that the Korean Tax Administration asserts should have been collected on a loan from ChipPAC’s Hungarian subsidiary to its Korean subsidiary. ChipPAC believes that no withholding on the transaction in question is required under the prevailing tax treaty. ChipPAC has appealed this assessment and believes that such assessment should be overturned. However, ChipPAC’s interpretations are not, and the combined company’s interpretations will not be, binding on any taxing authority and, if these foreign jurisdictions were to change or to modify the relevant laws, ChipPAC or the combined company could suffer adverse tax and other financial consequences or the anticipated benefits of ChipPAC’s corporate structure could be materially impaired.

Judgments of U.S. courts against STATS or the combined company may not be enforceable outside of the United States.

STATS is, and the combined company will be, a public limited company organized under the laws of the Republic of Singapore. Several of STATS’ and the combined company’s directors and officers and experts named in this document are nonresidents of the United States, and a significant portion of the assets of STATS, the combined company and these persons are located outside the United States. As a result, it may not be possible for investors to effect service of process within the United States upon these persons or to enforce, in courts outside the United States, judgments against such persons obtained in U.S. courts or predicated upon the civil liability provisions of the laws of the United States, including the U.S. securities laws. Furthermore, since a substantial portion of the assets of STATS and the combined company are located outside the United States, any judgment obtained in the United States against STATS or the combined company may not be collectible within the United States. STATS has been advised that judgments of U.S. courts based on the civil liability provisions of the U.S. securities laws of the United States are not enforceable in Singapore courts. STATS has also been advised that there is doubt as to whether Singapore courts will enter judgments in original actions brought in Singapore courts based solely upon the civil liability provisions of the federal securities laws of the United States.

The rights of STATS shareholders are materially different and in certain respects more limited than the rights of ChipPAC stockholders.

The corporate affairs of STATS and the combined company will be governed by the STATS memorandum of association and articles of association and Singapore law. The corporate affairs of ChipPAC are governed by the ChipPAC certificate of incorporation, ChipPAC bylaws and Delaware law. There are material differences between the organizational documents of STATS and ChipPAC and the laws governing their respective corporate affairs, including, without limitation, the following:

In addition, to the extent that similar rights exist under the organizational documents of or under applicable laws relating to STATS and ChipPAC, the standard of care and/or nature or extent of damages or other remedies available may be different.

For additional information regarding the rights of STATS shareholders and a summary of certain material differences between the rights of holders of STATS ordinary shares and holders of ChipPAC Class A common stock, see “Description of STATS Ordinary Shares” beginning on page 140, “Description of STATS American Depositary Shares” beginning on page 144 and “Comparison of Shareholder Rights” beginning on page 153.

The rights of holders of STATS ordinary shares are materially different from the rights of holders of STATS ADSs.

STATS ordinary shares represent equity interests in STATS and are governed by the STATS memorandum of association, the STATS articles of association and Singapore law. The STATS ADSs represent ownership interests in the STATS ordinary shares and other property on deposit with Citibank, N.A., the STATS depositary bank, on behalf of the STATS ADS holders and are governed by the terms and conditions of the deposit agreement, dated as of February 8, 2000, among STATS, the STATS depositary and the holders and beneficial owners from time to time of the American Depositary Shares evidenced by American Depositary Receipts (the STATS ADRs) issued thereunder (the STATS deposit agreement) and the STATS ADR that represents the STATS ADSs. There are material differences between the rights of holders of STATS ordinary shares and holders of STATS ADSs, including, without limitation, the following:

For additional information regarding the rights to holders of STATS ordinary shares and holders of STATS ADSs, see “Description of STATS Ordinary Shares” beginning on page 140 and “Description of STATS American Depositary Shares” beginning on page 144.

As a foreign private issuer, the combined company will be subject to different U.S. securities laws and rules than ChipPAC, which may, among other things, limit the information available to holders of STATS ordinary shares and STATS ADSs.

As a foreign private issuer, STATS is, and the combined company will be, subject to requirements under the Securities Act of 1933, as amended (the Securities Act), and the Securities Exchange Act of 1934, as amended (the Exchange Act), which are different from the requirements applicable to ChipPAC prior to the merger. For example, the combined company will not be required to comply with the notice and disclosure requirements under the Exchange Act relating to the solicitation of proxies for shareholder meetings. In addition, STATS’ officers, directors and principal shareholders will be exempt from the reporting and “short-swing” profit recovery provisions of Section 16 of the Exchange Act and the rules thereunder with respect to their purchases and sales of STATS ordinary shares and/or STATS ADSs. The periodic disclosure required of foreign private issuers is more limited than the periodic disclosure required of U.S. issuers and therefore there may be less publicly available information about the combined company than is regularly published by or about U.S. public companies in the United States.

The trading volume for STATS ADSs on the Nasdaq National Market has historically been more limited than the trading market for STATS ordinary shares on the Singapore Exchange which may adversely affect the ability of the holders of STATS ADSs to buy or sell STATS ADSs in a timely manner, if at all.

The STATS ADSs to be issued to ChipPAC stockholders will be quoted on the Nasdaq National Market under the symbol “STTS” and the STATS ordinary shares are listed on the Singapore Exchange under the symbol “ST Assembly”. The average weekly trading volume for the STATS ADSs over the past three months ending on June 25, 2004 has been approximately 90,684 STATS ADSs. This trading volume is substantially lower than then average weekly trading volume for the STATS ordinary shares on the Singapore Exchange, which was approximately 20,490,500 STATS ordinary shares, over the same three-month period. While a holder of STATS ADSs is entitled to surrender such holder’s STATS ADSs and receive the underlying STATS ordinary shares, such holder will need to pay certain fees, charges and taxes. See “Description of STATS American Depositary Shares” beginning on page 144. No assurances can be made that a more active trading market for the STATS ADSs on the Nasdaq National Market will develop after the consummation of the merger.

The date, time and place of the STATS extraordinary general meeting are as follows:

In connection with the proposed merger between STATS and ChipPAC, the STATS board of directors has convened the STATS extraordinary general meeting for August 4, 2004. At the meeting, STATS will propose the following STATS resolutions:

Each of the STATS resolutions will be voted on separately at the STATS extraordinary general meeting. If any of STATS resolutions 1 through 8 and 12 does not receive the requisite approval of the STATS shareholders, none of STATS resolutions 1 through 10 and 12 will be deemed approved by the STATS shareholders and the merger will not be consummated. STATS resolutions 9 and 10 are contingent upon the consummation of the merger and, even if such resolutions receive the requisite STATS shareholder approval, will be deemed approved by STATS shareholders only if the merger is consummated. STATS resolution 11 is not contingent upon the consummation of the merger and therefore will be approved if it receives the requisite STATS shareholder approval. For additional information regarding the STATS proposals, see “STATS Proposals at the STATS Extraordinary General Meeting” beginning on page 122.

The STATS board of directors has, by unanimous vote of the directors voting at the meeting of the STATS board of directors to consider the merger, determined that the merger is consistent with and in furtherance of the long-term business strategy of STATS and fair to and in the best interests of the holders of the STATS ordinary shares and STATS ADSs. In addition, at a subsequent meeting, the STATS board of directors adopted the recommendation of the STATS audit committee to appoint PricewaterhouseCoopers, Singapore as auditors to STATS. Accordingly, after careful consideration, the STATS board of directors has approved and declared advisable the merger, the merger agreement and the appointment of PricewaterhouseCoopers, Singapore as auditors to STATS, and recommends that STATS shareholders vote FOR the approval of all of the STATS resolutions.

Any two or more shareholders of STATS holding or representing in the aggregate not less than one third of the outstanding STATS ordinary shares present in person or by proxy at the STATS extraordinary general meeting will constitute a quorum.

Holders of STATS ordinary shares who are registered with the CDP as of 48 hours before the time set for the STATS extraordinary general meeting, or by 10:00 a.m., Singapore time, on August 2, 2004, shall be entitled to vote at the STATS extraordinary general meeting.

At the close of business on June 16, 2004, there were 1,076,841,260 STATS ordinary shares issued and outstanding held by 32,033 owners.

To be effective, a proxy must be deposited at STATS’ registered office located at 5 Yishun Street 23, Singapore 768442, at least 48 hours before the time set for the STATS extraordinary general meeting, or by 10:00 a.m., Singapore time, on August 2, 2004, or at any adjournment thereof. A proxy need not be a STATS shareholder. STATS shareholders may appoint any member of the STATS board of directors or any other person as their proxy.

Any STATS shareholder signing a proxy in the form accompanying this document has the power to revoke it either prior to the STATS extraordinary general meeting at which the matter voted by the proxy is acted upon, or at the STATS extraordinary general meeting prior to the vote on the matter. A proxy may be revoked, at any time not less than 48 hours before the time set for the STATS extraordinary general meeting, by submitting a subsequently dated instrument appointing a proxy or, at the STATS extraordinary general meeting prior to the vote on the STATS resolutions, by such shareholder attending the STATS extraordinary general meeting and voting in person.

On a show of hands, every holder of STATS ordinary shares present in person or by proxy shall have one vote. On a poll, every holder of STATS ordinary shares present in person or by proxy shall have one vote for each STATS ordinary share held. A resolution put to a vote of STATS shareholders at the STATS extraordinary general meeting will be decided on a show of hands unless a poll is demanded. A poll may be demanded in certain circumstances, including by:

provided always that no poll shall be demanded on the choice of a chairman or on a question of adjournment.

STATS ordinary shares represented by duly elected proxies deposited with STATS will be voted at the STATS extraordinary general meeting in accordance with the instructions of the STATS shareholder’s instructions contained in the proxy. In the absence of specific instructions in the proxy, the proxy of a STATS shareholder may vote or abstain as such proxy sees fit.

On a show of hands, each of STATS resolutions 1 through 11 will be duly passed by the affirmative vote of a simple majority of STATS shareholders present in person or by proxy and voting at the extraordinary general meeting, and STATS resolution 12 will be duly passed by an affirmative vote of not less than three-fourths of STATS shareholders present in person or by proxy and voting at the STATS extraordinary general meeting. If a poll is demanded, each of STATS resolutions 1 through 11 will be duly passed by the affirmative vote of a simple majority of votes cast at the STATS extraordinary general meeting for each STATS ordinary share held, and STATS resolution 12 will be duly passed by an affirmative vote of not less than three-fourths of votes cast at the STATS extraordinary general meeting for each STATS ordinary share held.

Certain shareholders, directors and officers of STATS and their affiliates, who as of June 16, 2004 together owned a total of approximately 59.2% of the outstanding STATS ordinary shares, have entered into the STATS voting agreement and have agreed to vote all STATS ordinary shares and STATS ADSs owned of record by such shareholder in favor of the issuance of STATS ordinary shares in the merger and certain other matters related to the merger. As a result, approval of STATS resolutions 1 through 8 at the STATS extraordinary general meeting is assured.

The STATS board of directors is soliciting proxies from STATS shareholders for use at the STATS extraordinary general meeting, and any adjournment or postponement of the STATS extraordinary general meeting.

STATS will pay the costs of soliciting proxies to be voted at the STATS extraordinary general meeting, except that the expense of printing and mailing proxy materials will be divided equally by STATS and ChipPAC. In addition to the solicitation of proxies by mail, solicitation may be made by certain directors, officers and other employees of STATS by personal interview, telephone or facsimile. No additional compensation will be paid for such solicitation. STATS will request brokers and nominees who hold STATS ordinary shares in their names and the STATS depositary to furnish proxy materials to the beneficial owners of the STATS ordinary shares and STATS ADSs and will reimburse such brokers and nominees for their reasonable expenses incurred in forwarding solicitation materials to such beneficial owners.

Do not send in any certificates representing STATS ordinary shares or STATS ADSs with your proxy.

To assure that your STATS ordinary shares are represented at the STATS extraordinary general meeting, please complete, date and sign the enclosed proxy in accordance with the instructions printed thereon and mail it as soon as possible and in any event so as to arrive at 5 Yishun Street 23, Singapore 768442 no later than 10:00 a.m., Singapore time, on August 2, 2004, whether or not you plan to attend the STATS extraordinary general meeting. STATS shareholders may revoke their proxy at any time not less than 48 hours before the time set for the STATS extraordinary general meeting by submitting a subsequently dated instrument appointing a proxy or, at the STATS extraordinary general meeting prior to the vote on the STATS resolutions, by such shareholder attending the STATS extraordinary general meeting and voting in person.

If you hold STATS ADSs, please review the enclosed STATS ADS Voting Instructions Card and Depositary Notice of STATS Extraordinary General Meeting for an explanation of how you may instruct the STATS depositary to vote the STATS ordinary shares underlying your STATS ADSs at the STATS extraordinary general meeting. Please complete the enclosed STATS ADS Voting Instructions Card and return it to Citibank Shareholder Services, P.O. Box 8527, Edison, New Jersey 08818-9395 as soon as possible and in any event so as to arrive no later than 10:00 a.m., New York time on July 28, 2004.

ChipPAC is furnishing this document to holders of ChipPAC Class A common stock in connection with the solicitation of proxies by the ChipPAC board of directors for use at the special meeting of ChipPAC stockholders to be held on August 4, 2004, and any adjournment or postponement of the special meeting.

The date, time and place of the special meeting of ChipPAC stockholders are as follows:

The ChipPAC board of directors has, by unanimous vote of the directors voting at the meeting of the ChipPAC board of directors to consider the merger, concluded that the merger is fair to, and in the best interests of, ChipPAC and its stockholders and has approved the merger, the merger agreement and the associated transactions. Accordingly, the ChipPAC board of directors has declared advisable, and recommends, that ChipPAC stockholders vote FOR adoption and approval of the merger agreement and approval of the merger.

The ChipPAC board of directors has fixed the close of business on June 16, 2004 as the record date for the ChipPAC special meeting. Only holders of record of ChipPAC Class A common stock on the ChipPAC record date are entitled to notice of, and to vote at, the ChipPAC special meeting. At the close of business on the ChipPAC record date, ChipPAC had outstanding and entitled to vote 98,553,175 shares of Class A common stock, held by approximately 58 stockholders of record.

Holders of ChipPAC Class A common stock are entitled to one vote for each share held as of the record date. Adoption and approval of the merger agreement and approval of the merger will require the affirmative vote of the holders of a majority of the outstanding shares of ChipPAC Class A common stock. A quorum of ChipPAC stockholders is required to hold a valid special meeting. Attendance at the meeting in person or by proxy of holders of a majority of the shares of ChipPAC Class A common stock outstanding and entitled to vote on the record date is required for a quorum.

Certain stockholders and directors of ChipPAC and Mr. McKenna, the President and Chief Executive Officer of ChipPAC and Chairman of the ChipPAC board of directors, who, as of the ChipPAC record date, together owned a total of approximately 17.9% of the outstanding ChipPAC Class A common stock, have entered into the ChipPAC voting agreement and have agreed to vote all of the shares of ChipPAC Class A common stock owned of record by such stockholder in favor of the adoption and approval of the merger agreement and the approval of the merger.

On the record date, directors and executive officers of ChipPAC and their affiliates owned, and were entitled to vote, approximately 17,906,326 shares of ChipPAC Class A common stock, or approximately 18.2% of the outstanding voting shares. Certain directors and one of the executive officers of ChipPAC and their affiliates, who, as of the ChipPAC record date, together owned a total of approximately 17.9% of the outstanding ChipPAC Class A common stock, have entered into the ChipPAC voting agreement and have agreed to vote all of the shares of ChipPAC Class A common stock owned by such stockholder of record in favor of the adoption and approval of the merger agreement and the approval of the merger. In addition, such directors and officers have granted STATS an irrevocable proxy to vote their shares of ChipPAC Class A common stock in favor of adoption and approval of the merger agreement and approval of the merger. See “Agreements Related to the Merger—ChipPAC voting agreement” on page 117.

Abstentions and broker non-votes each will be included in determining the number of shares of ChipPAC Class A common stock present and voting at the ChipPAC special meeting for the purpose of determining the presence of a quorum. Because adoption and approval of the merger agreement and approval of the merger require the affirmative vote of a majority of the outstanding shares of ChipPAC Class A common stock entitled to vote, abstentions and broker non-votes will have the same effect as votes against the adoption and approval of the merger agreement and approval of the merger. In addition, the failure of a ChipPAC stockholder to return a proxy or vote in person will have the effect of a vote against the adoption and approval of the merger agreement and approval of the merger. Brokers holding shares of ChipPAC Class A common stock for beneficial owners cannot vote on the actions proposed in this document without the beneficial owners’ specific instructions.

ChipPAC will pay the costs of soliciting proxies to be voted at the ChipPAC special meeting, except that STATS will share equally the expenses incurred in connection with filing and printing this document. Arrangements will also be made with brokerage firms and custodians, nominees and fiduciaries who are record holders of ChipPAC Class A common stock for the forwarding of proxy solicitation materials to the beneficial owners of ChipPAC Class A common stock. ChipPAC will reimburse these brokers, custodians, nominees and fiduciaries for reasonable out-of-pocket expenses they incur in connection with the forwarding of proxy solicitation materials.

ChipPAC has retained MacKenzie Partners, Inc. to assist in the solicitation of proxies from banks, brokerage firms, nominees, institutional holders and individual investors for a customary fee, plus expenses relating to the solicitation.

In addition to solicitation by mail, directors, officers, employees and agents of ChipPAC may solicit proxies in person or by telephone, telegram or other means of communication. These persons will receive no additional compensation for solicitation of proxies but may be reimbursed for reasonable out-of-pocket expenses.

The proxy accompanying this document is solicited on behalf of the ChipPAC board of directors for use at the ChipPAC special meeting. Please complete, date, sign and return the accompanying proxy as soon as possible.

All properly signed proxies that are not revoked will be voted at the ChipPAC special meeting, and at any adjournments or postponements of the ChipPAC special meeting, according to the instructions indicated on the proxies. If a holder of ChipPAC Class A common stock properly executes and returns a proxy and does not specify otherwise, the shares represented by that proxy will be voted FOR the proposal to adopt and approve the merger agreement and to approve the merger at the ChipPAC special meeting. If any other matters are properly brought before the ChipPAC special meeting, the persons named in the proxies will have discretion to vote on such matters.

ChipPAC stockholders whose broker holds such stockholder’s shares of ChipPAC Class A common stock in “street name” should instruct their broker to vote their shares of ChipPAC Class A common stock, following the broker’s directions. Most brokers have procedures for telephone or Internet voting. ChipPAC stockholders should review the material sent to them by their broker or call their account representative for more information. In the event that a ChipPAC stockholder does not instruct their broker as to how their shares of ChipPAC Class A common stock held in “street name” should be voted, such shares will not be voted for the adoption and approval of the merger agreement and the approval of the merger or for any other proposal with respect to which the broker does not have discretionary authority.

ChipPAC stockholders may revoke their proxy at any time before it is exercised at the ChipPAC special meeting by taking any of the following actions:

Please note, however, that if shares of ChipPAC Class A common stock are held of record by a broker, bank or other nominee and the beneficial owner of such shares wishes to vote at the ChipPAC special meeting, such owner must bring to the meeting a letter from the broker, bank or other nominee confirming such owner’s beneficial ownership of the shares of ChipPAC Class A common stock.

Do not send in any stock certificates with the proxy. The exchange agent will mail transmittal forms with instructions for the surrender of stock certificates for ChipPAC Class A common stock to former ChipPAC stockholders as soon as practicable after the completion of the merger.

To assure that your shares of ChipPAC Class A common stock are represented at the ChipPAC special meeting, please complete, date and sign the enclosed proxy and mail it promptly in the postage-paid envelope provided, whether or not you plan to attend the ChipPAC special meeting. ChipPAC stockholders may revoke their proxy at any time before it is voted at the ChipPAC special meeting.

This section of this document describes the material aspects of the proposed merger. While STATS and ChipPAC believe that the description covers the material terms of the merger and the related transactions, this summary may not contain all of the information that is important to you. You should carefully read this entire document and the other documents STATS and ChipPAC refer to in this document for a more complete understanding of the merger.

In accordance with the merger agreement and Delaware law, Camelot Merger, Inc., which is a newly formed, wholly owned subsidiary of STATS, will be merged with and into ChipPAC. As a result of the merger, the separate corporate existence of Camelot Merger, Inc. will cease and ChipPAC will survive the merger as a wholly owned subsidiary of STATS.

In the merger, holders of ChipPAC Class A common stock will receive 0.87 STATS ADSs for each share of ChipPAC Class A common stock they hold. The number of STATS ADSs that holders of ChipPAC Class A common stock will receive in the merger will be appropriately adjusted for any stock splits, combinations and other similar events that occur between the date of the merger agreement and the completion of the merger. STATS will not issue fractional STATS ADSs in the merger. Instead, each holder of shares of ChipPAC Class A common stock exchanged in the merger who would otherwise have received a fraction of a STATS ADS will receive cash, without interest, in an amount equal to the holder’s proportionate interest in the gross proceeds of the sale on the Nasdaq National Market by the exchange agent of the aggregated fractional STATS ADSs that otherwise would be issued in the merger. STATS will pay all commissions, transfer taxes and out-of-pocket costs, including the expenses and compensation of the exchange agent, incurred in connection with the sale by the exchange agent of the STATS ADSs.

Treatment of ChipPAC stock options; Adoption of STATS ChipPAC substitute share option plans

At the effective time of the merger, each ChipPAC stock option granted under the ChipPAC 1999 plan and the ChipPAC 2000 plan that is outstanding and unexercised immediately prior to the effective time of the merger will be substituted with a STATS substitute option to purchase a number of STATS ordinary shares equal to the number of shares of ChipPAC Class A common stock subject to such ChipPAC option multiplied by 8.7 (ten times the exchange ratio), at a per STATS ordinary share exercise price equal to the exercise price per share of the substituted ChipPAC option divided by 8.7 (ten times the exchange ratio), subject to certain limitations. Upon exercise of a STATS substitute option, the holder of the STATS substitute option may elect to receive, in lieu of STATS ordinary shares, a number of STATS ADSs equal to the number of STATS ordinary shares subject to the STATS substitute option divided by ten and rounded down to the nearest whole STATS ADS.

The STATS substitute options will be granted under the STATS ChipPAC substitute share option plan or the STATS ChipPAC substitute EIP, subject to receipt of the requisite approval of the STATS shareholders at the STATS extraordinary general meeting. For a description of the STATS ChipPAC substitute share option plan and the STATS ChipPAC substitute EIP, please see “STATS Proposals at the STATS Extraordinary General Meeting—Resolution 2” beginning on page 123.

STATS will file registration statements with the SEC that registers the resale of STATS ordinary shares and the STATS ADSs that will be issuable upon the exercise of the STATS substitute options following the merger. STATS will use its reasonable best efforts to have these registration statements declared effective as soon as practicable after the consummation of the merger.

As of March 31, 2004, ChipPAC had outstanding $150 million aggregate principal amount of ChipPAC 2.5% convertible subordinated notes and $50 million aggregate principal amount of ChipPAC 8% convertible subordinated notes and had guaranteed $165 million aggregate principal amount of ChipPAC senior subordinated notes. The ChipPAC 2.5% convertible subordinated notes were issued under an indenture, dated as of May 28, 2003 (the ChipPAC 2.5% notes indenture), between ChipPAC and U.S. Bank National Association, as trustee. The ChipPAC 2.5% notes indenture provides that after the consummation of the merger, the holders of the ChipPAC 2.5% convertible subordinated notes will be entitled to convert such notes into the number of STATS ADSs that they would have received in the merger if they had converted such notes into ChipPAC Class A common stock immediately prior to the merger. If the ChipPAC 2.5% convertible subordinated notes are outstanding at the time the merger is consummated, as a condition precedent to the merger, STATS and the trustee must enter into a supplemental indenture to implement this modification in the conversion rights of the ChipPAC 2.5% convertible subordinated notes. The merger will not constitute a “change of control”, as defined in the ChipPAC 2.5% notes indenture, and accordingly the holders of the ChipPAC 2.5% convertible subordinated notes will not have the right to require ChipPAC to repurchase such notes.

The ChipPAC 8% convertible subordinated notes were issued under an indenture, dated as of June 15, 2001 (the ChipPAC 8% notes indenture), between ChipPAC and Firstar Bank, N.A., as trustee. The ChipPAC 8% notes indenture provides that after the consummation of the merger, the holder of the ChipPAC 8% convertible subordinated notes will be entitled to convert such notes into the number of STATS ADSs that it would have received in the merger if it had converted such notes into ChipPAC Class A common stock immediately prior to the merger. If the ChipPAC 8% convertible subordinated notes are outstanding at the time the merger is consummated, as a condition precedent to the merger, STATS and the trustee must enter into a supplemental indenture to implement this modification in the conversion rights of the ChipPAC 8% convertible subordinated notes. The merger may constitute a “change of control”, as defined in the ChipPAC 8% notes indenture. Pursuant to the ChipPAC 8% notes indenture, the merger will not constitute a “change of control” if, among things, the closing price of shares of ChipPAC Class A common stock for any five trading days during the ten trading days immediately preceding the consummation of the merger is at least equal to 105% of the conversion price for the ChipPAC 8% convertible subordinated notes in effect on such trading day (such conversion price is currently $9.96). If the merger does constitute a “change of control” as defined in the ChipPAC 8% notes indenture, the holder of the ChipPAC 8% convertible subordinated notes will have the right to require ChipPAC to repurchase such convertible subordinated notes at a purchase price in cash equal to the principal amount plus any accrued and unpaid interest to the date of repurchase.

Under the indenture, dated as of July 29, 1999 (the ChipPAC senior subordinated notes indenture), between ChipPAC and Firstar Bank of Minnesota, N.A., as trustee, governing the ChipPAC senior subordinated notes, the merger will constitute a “change of control”, as defined in such indenture, and accordingly the holders of the ChipPAC senior subordinated notes will have the right to require ChipPAC to repurchase such senior subordinated notes at a purchase price in cash equal to 101% of the principal amount plus any accrued and unpaid interest to the date of repurchase.

STATS will file registration statements with the SEC that registers the resale of STATS ADSs that will be issuable upon the conversion of the ChipPAC 2.5% convertible subordinated notes or the ChipPAC 8% convertible subordinated notes following the merger, as well as the STATS ordinary shares underlying the STATS ADSs, and STATS will use its reasonable best efforts to have these registration statements declared effective as soon as practicable after the effective time of the merger.

At the consummation of the merger, each of Messrs. Koh, Meder, Teng and Quek will resign from the STATS board of directors and, subject to their election at the STATS extraordinary general meeting, four persons who have been designated by ChipPAC will serve as directors of STATS. ChipPAC has designated Dr. Conn, Mr. McKenna, Mr. Norby and Dr. Park to be nominated for election to the STATS board of directors. In

addition, one of Dr. Conn, Mr. Norby or Dr. Park will be appointed to the STATS audit committee. If Mr. McKenna is elected to the STATS board of directors, he will be appointed as Vice Chairman of the STATS board of directors and will serve in that capacity until December 31, 2004.

For additional information regarding the ChipPAC designees to be nominated for election to the STATS board of directors, see “Directors and Executive Officers of STATS” beginning on page 138.

At the effective time of the merger, STATS’ name will be changed to “STATS ChipPAC Ltd.”

For additional information regarding the proposed STATS name change, see “STATS Proposals at the STATS Extraordinary General Meeting—Resolution 12” beginning on page 137.

STATS and ChipPAC have been familiar with each other’s businesses for several years. In the early part of 2001, Mr. McKenna, Chairman, President and Chief Executive Officer of ChipPAC, met with then-Chairman of the STATS board of directors and Chief Executive Officer, Mr. Tan Bock Seng, to discuss a possible transaction between the companies. The parties preliminarily discussed a transaction in which STATS would acquire ChipPAC in a stock-for-stock transaction. Although preliminary discussions took place over several months, no agreement was reached at that time.

In the latter half of 2001, ChipPAC and STATS again engaged in preliminary discussions regarding a possible combination of the companies. In these discussions, the parties discussed a transaction in which, among other things, (i) STATS would acquire ChipPAC in a transaction in which ChipPAC Class A common stock would be exchanged for STATS ADSs at a fixed exchange ratio, (ii) the initial board of directors of the combined company would be comprised of numbers of STATS directors and ChipPAC directors proportional to the relative pro forma ownership of the combined company, (iii) the principal shareholders of STATS and ChipPAC would make capital contributions to the combined company, and (iv) ChipPAC stockholders would own approximately 35% to 40% of the combined company. During the first two weeks of November 2001, ChipPAC and STATS exchanged diligence materials, and on November 9, 2001, ChipPAC and STATS conducted management presentations and had preliminary due diligence meetings in Pebble Beach, California. After these meetings, the parties terminated discussions without any agreement being reached.

In December 2002, Mr. McKenna met in Singapore with STATS’ newly-appointed Chief Executive Officer, Mr. Tan Lay Koon, to discuss the possibility of reviving discussions regarding a possible business combination. Mr. Tan requested that Mr. McKenna make a preliminary proposal regarding such a transaction. Mr. McKenna sent a proposal letter to STATS as requested on December 20, 2002. Mr. McKenna proposed a transaction in which shareholders of STATS and ChipPAC would each own 50% of the combined company. After consultation with the STATS board of directors, Mr. Tan informed Mr. McKenna that the STATS board of directors considers various strategic alternatives from time to time and took note of ChipPAC’s interest in STATS, but STATS did not otherwise respond to ChipPAC’s proposal.

In the first half of November 2003, Mr. McKenna contacted Mr. Tan in an effort to re-initiate discussions regarding a possible business combination. On November 14, 2003, the ChipPAC board of directors met to consider a possible transaction with STATS. Following this discussion, the ChipPAC board of directors authorized Mr. McKenna to make a written proposal to STATS. Later that day, Mr. McKenna delivered a written proposal to STATS that contemplated a transaction in which, among other things, (i) ChipPAC Class A common stock would be exchanged for STATS ADSs at an exchange ratio to be fixed prior to the announcement of the transaction and (ii) the initial board of directors of the combined company would be comprised of numbers of STATS directors and ChipPAC directors proportional to the relative pro forma ownership of the combined

company, with each of STATS and ChipPAC jointly choosing independent directors. The proposed exchange ratio would, assuming then current market prices for both companies’ stock, reflect a 65% premium over the trailing 30-day average ratio of the market prices of the STATS ADSs and ChipPAC Class A common stock with the measurement period ending five business days prior to the announcement of the proposed transaction, subject to a minimum exchange ratio of 0.77 and a maximum exchange ratio of 0.95 of a STATS ADS for each ChipPAC share.

Mr. Tan discussed ChipPAC’s proposal with the executive committee of the STATS board of directors on November 27, 2003 and was authorized to respond to ChipPAC’s proposal. On December 3, 2003, Mr. Tan delivered a letter to Mr. McKenna containing a revised proposal for a possible business combination. In this proposal, (i) the initial board of directors of the combined company would be comprised of numbers of STATS and ChipPAC directors proportional to the relative pro forma ownership of the combined company, including one director designated by each of ChipPAC’s two principal stockholders, (ii) each of ChipPAC’s two principal shareholders would agree to certain resale restrictions on STATS ADSs to be received in the merger, and (iii) the proposed exchange ratio would reflect a 50% premium over the trailing 30-day average ratio of the market prices of the STATS ADSs and ChipPAC Class A common stock, subject to a minimum exchange ratio of 0.70 and a maximum exchange ratio of 0.85 of a STATS ADS for each ChipPAC share. This proposal also outlined certain principal conditions for a proposed transaction, including satisfactory completion of due diligence investigations, negotiation of mutually satisfactory agreements, board approval and other conditions.

On December 5, 2003, the ChipPAC board of directors met to consider the counterproposal received from STATS, and authorized Mr. McKenna and Credit Suisse First Boston, ChipPAC’s financial advisor, to continue discussions with STATS and STATS’ financial advisor, Morgan Stanley, regarding the terms of a possible transaction. After this meeting, Mr. McKenna telephoned Mr. Tan to discuss the proposal and the two agreed to proceed with preliminary discussions with respect to a possible transaction.

On December 13, 2003, Mr. Tan sent a revised proposal to Mr. McKenna. In the revised proposal, the proposed exchange ratio would, assuming then current market prices for both companies’ stock, reflect a 50% premium over the trailing 30-day average ratio of the market prices of STATS ADSs and ChipPAC Class A common stock with the measurement period ending five business days prior to the announcement of the proposed transaction, subject to a minimum exchange ratio of 0.75 and a maximum exchange ratio of 0.87 of a STATS ADS for each ChipPAC share. This proposal also indicated that the current Chairman of the STATS board of directors would remain Chairman of the STATS board of directors of the combined company following completion of the merger. Following review by the ChipPAC board of directors, Mr. McKenna communicated to Mr. Tan ChipPAC’s willingness to attempt to negotiate a definitive agreement having the basic terms reflected in Mr. Tan’s December 13th letter and he suggested that the parties proceed with the next step of due diligence.

Throughout the last half of December 2003 and early January 2004, representatives of STATS and ChipPAC, and their respective legal and financial advisors, participated in telephone conference calls to discuss, among other things, structural alternatives for a possible business combination between STATS and ChipPAC. The parties discussed, among other forms of transactions, a transaction in which STATS would acquire ChipPAC pursuant to a reverse subsidiary merger and a transaction in which a newly formed holding company would acquire both STATS and ChipPAC. Throughout January 2004, STATS, ChipPAC, and their respective legal and financial advisors, discussed and evaluated the potential tax treatment of the proposed merger and alternative forms of transactions.

On January 6, 2004, STATS and ChipPAC signed a mutual non-disclosure agreement providing for the safeguarding of the confidentiality of information that the parties might share with each other during their discussions relating to a potential business combination.

In early January 2004, Mr. Tan and Mr. McKenna held a telephone conversation and agreed that a logical next step in the initial review processes of both parties was to conduct a joint meeting during which each party

would describe their business and organization. Mr. Tan and Mr. McKenna agreed that the parties should meet in Tokyo from January 10 through January 12.

From January 10 through January 12, 2004, a team from STATS consisting of Mr. Tan and senior executives of STATS, met at the offices of Morgan Stanley in Tokyo with Mr. McKenna and members of ChipPAC’s senior management team. Representatives of Shearman & Sterling LLP, STATS’ U.S. legal counsel, Kirkland & Ellis LLP, ChipPAC’s U.S. legal counsel, and STATS’ and ChipPAC’s respective financial advisors, also attended these meetings. During these meetings, each company’s management team made a series of presentations to representatives of the other company regarding their company’s business, financial condition and results of operations and held a number of one-on-one meetings to further their understanding of each company’s operations. Following these meetings, Mr. Tan and Mr. McKenna conducted a follow-up call and reviewed the preliminary discussions that occurred between the parties.

Starting on January 13, 2004, ChipPAC permitted STATS and its legal, financial and accounting advisors to access data rooms of due diligence documents that ChipPAC had established at the offices of Kirkland & Ellis LLP in San Francisco and at the offices of Rajah & Tann, ChipPAC’s Singapore legal counsel, in Singapore. From January 13, 2004 until the announcement of the proposed merger, representatives of STATS and its legal and financial advisors reviewed information regarding ChipPAC and conducted interviews of a number of members of ChipPAC senior management. During that same period, representatives of ChipPAC and its legal and financial advisors reviewed information regarding STATS at data rooms of due diligence documents that STATS had established at the offices of Shearman & Sterling LLP in San Francisco and Singapore and conducted a series of interviews of a number of members of STATS senior management.

On January 16, 2004, Shearman & Sterling LLP provided an initial draft of a merger agreement for the proposed transaction to Kirkland & Ellis LLP. From January 16, 2004 until the announcement of the proposed merger on February 10, 2004, the parties exchanged comments on the draft agreement and negotiated its terms.

On January 21, 2004, the ChipPAC board of directors met to discuss the proposed merger agreement and the discussions that took place between ChipPAC and STATS in Tokyo the preceding week. At that meeting, Mr. McKenna reviewed discussions regarding the transaction to date. Kirkland & Ellis LLP reviewed the fiduciary duties of the ChipPAC directors in the context of a proposed transaction of this type. Credit Suisse First Boston reviewed with the ChipPAC board of directors financial aspects of the proposed merger.

On January 26, 2004, the ChipPAC board of directors met again to continue their discussions and their review of the progress of negotiations between the parties. ChipPAC’s legal and financial advisors reported on the progress of negotiations with STATS.

On January 28, 2004, at a regularly scheduled meeting of the STATS board of directors, the STATS board of directors reviewed STATS’ results of operations for the quarter and year ended December 31, 2003 and discussed, among other things, the status of the negotiations with ChipPAC. After the Nasdaq National Market closed that day, STATS issued a press release announcing its results of operations for the quarter and year ended December 31, 2003.

On January 28, 2004, Shearman & Sterling LLP provided an initial draft of the voting agreements to Kirkland & Ellis LLP. From January 28, 2004 until the announcement of the proposed merger on February 10, 2004, the parties exchanged comments on the draft voting agreements and negotiated their terms.

On January 29, 2004, ChipPAC issued a press release announcing its results of operations for the quarter and year ended December 31, 2003.

On February 2, 2004, the ChipPAC board of directors met again to continue their review of the progress of negotiations between the parties. On that same day, the parties also submitted an initial ruling request letter to the

IRS, requesting, subject to the completion of negotiations and execution of a definitive merger agreement, a private letter ruling relating to the tax treatment of the proposed merger to ChipPAC’s stockholders.

On February 2, 2004, STATS and ChipPAC agreed, subject to completion of due diligence and negotiation of a definitive agreement, that the exchange ratio would be 0.87 STATS ADSs for each share of ChipPAC Class A common stock. This exchange ratio was agreed in accordance with the formula that the parties discussed on December 13, 2003 and in light of then current market prices for both companies’ stock and then current average ratios of the market prices of STATS ADSs and ChipPAC Class A common stock.

On February 5, 2004, the ChipPAC board of directors held a regularly scheduled meeting during which they reviewed and discussed the terms of the merger agreement and the progress of negotiations between the parties.

Following these presentations, the STATS board of directors discussed the proposed transaction and the matters presented to it and authorized STATS management to continue its negotiations with ChipPAC.

Also on February 9, 2004, the ChipPAC board of directors met to discuss the terms of the proposed merger and consider its advisability. ChipPAC management and ChipPAC’s legal and financial advisors also attended this meeting. Kirkland & Ellis LLP reviewed the outcome of negotiations with STATS and responded to questions from the ChipPAC directors. Credit Suisse First Boston reviewed with the ChipPAC board of directors its financial analysis of the exchange ratio provided for in the proposed merger and rendered to the ChipPAC board its oral opinion, which opinion was confirmed by delivery of a written opinion dated February 9, 2004, to the effect that, as of that date and based on and subject to the matters described in its opinion, the exchange ratio was fair to the holders of ChipPAC Class A common stock, from a financial point of view. Following the presentations and after discussion, the ChipPAC board of directors approved the merger agreement and the transactions contemplated by the merger agreement.

Following the meetings, representatives of STATS and ChipPAC, and their respective legal and financial advisors, participated in several telephone conference calls to finalize the merger agreement and related documentation.

On February 10, 2004, STATS contacted the Singapore Exchange while trading was closed during the lunch hour in Singapore to suspend trading in STATS ordinary shares during the afternoon session. The STATS board of directors met at 1:30 pm, Singapore time on Tuesday, February 10, at which meeting Mr. Tan updated the STATS board of directors on the final terms of the merger. A representative of Morgan Stanley rendered to the

STATS board of directors the oral opinion of Morgan Stanley, which was subsequently confirmed by delivery of a written opinion dated February 10, 2004, to the effect that, as of the date of the written opinion and based upon and subject to the various considerations contained in the written opinion, the exchange ratio under the merger agreement was fair from a financial point of view to STATS. Representatives of Allen & Gledhill, STATS’ Singapore legal counsel, reviewed with the STATS board of directors the proposed form of board resolutions to approve the proposed transaction and the merger agreement and related documents.

After taking into consideration all of the factors set forth above, the ChipPAC board of directors concluded that the merger was fair to, and in the best interests of, ChipPAC and its stockholders (other than STATS and its affiliates) and that ChipPAC should proceed with the merger. Accordingly, the ChipPAC board of directors adopted the merger agreement and approved the merger and the associated transactions and recommended that ChipPAC stockholders vote FOR the adoption and approval of the merger agreement and approval of the merger.

STATS retained Morgan Stanley to provide the STATS board of directors with financial advisory services and an opinion as to the fairness to STATS, from a financial point of view, of the exchange ratio under the merger agreement. Morgan Stanley was selected based on its qualifications, expertise and reputation and its knowledge of the business and affairs of STATS. At a meeting of the STATS board of directors on February 10, 2004, Morgan Stanley rendered its oral opinion to the STATS board of directors, confirmed by delivery of a written opinion dated February 10, 2004, that, as of the date of the written opinion and based upon and subject to the various considerations contained in the written opinion, the exchange ratio under the merger agreement was fair from a financial point of view to STATS.

The full text of Morgan Stanley’s written opinion dated February 10, 2004, which contains, among other things, the assumptions made, procedures followed, matters considered and limitations on the review undertaken, is attached as Annex D to this document. Morgan Stanley’s written opinion is addressed to the STATS board of directors and covers only the fairness of the exchange ratio from a financial point of view to STATS as of the date of the opinion. Morgan Stanley’s written opinion expresses no opinion at all as to ChipPAC’s or STATS’ underlying decision to effect the merger, or as to any other aspect of the merger. The Morgan Stanley opinion does not constitute a recommendation to any STATS ADS holder, STATS shareholder or ChipPAC stockholder as to how they should vote on the issuance of STATS ADSs in the merger or the other matters related to the merger. The summary of the Morgan Stanley opinion contained in this document is qualified by reference to the full text of the Morgan Stanley opinion attached as Annex D, which should be read carefully and in its entirety.

In arriving at its opinion, Morgan Stanley assumed and relied upon, without independent verification, the accuracy and completeness of all information supplied or otherwise made available to it by ChipPAC and/or STATS for the purposes of its opinion. With respect to financial forecasts, Morgan Stanley assumed that they had been reasonably prepared on bases reflecting the best currently available estimates and judgments of the future financial performance of ChipPAC and STATS by their respective managements. Morgan Stanley did not make any independent valuation or appraisal of the assets and liabilities of ChipPAC or STATS, nor was Morgan Stanley furnished with any independent valuation or appraisal of those assets or liabilities.

Morgan Stanley also relied, without independent verification, upon the assessment of the management of ChipPAC and the management of STATS of:

Morgan Stanley also assumed that in the course of obtaining any necessary approvals and consents required for the merger, no restrictions would be imposed that would have a material adverse effect on the benefits expected by ChipPAC and STATS to be derived from the proposed merger. In addition, Morgan Stanley assumed that the merger would be completed in accordance with the merger agreement, including, among other things, that the merger would be treated as a tax-free reorganization under the Internal Revenue Code.

Morgan Stanley’s opinion is necessarily based on financial, economic, market and other conditions as in effect on the date of the opinion, and the information made available to Morgan Stanley as of the date of the opinion. Morgan Stanley’s opinion does not address the relative merits of the transactions contemplated by the merger agreement as compared to any other alternative transactions, whether or not any of those alternative transactions could be achieved. In addition, Morgan Stanley is not an expert in accounting, legal or tax matters, and its opinion does not address any advice rendered by ChipPAC’s or STATS’ respective accountants, legal counsel or tax advisors with respect to the merger. Morgan Stanley’s opinion does not address the prices at which the ChipPAC Class A common stock, STATS ordinary shares or STATS ADSs will trade following the announcement or completion of the merger, or as to the financial performance of ChipPAC or STATS following completion of the merger.

The following is a brief summary of the material financial analyses performed by Morgan Stanley in connection with giving its opinion. Some of these summaries include information presented in tables. In order to fully understand the financial analyses used by Morgan Stanley, these tables must be read together with the text of each summary. The tables alone do not constitute a complete description of the financial analyses.

Based on financial data and estimates provided by the management of STATS and ChipPAC, Morgan Stanley analyzed the respective contributions by STATS and ChipPAC to the combined company by comparing their respective percentage contributions to the revenues, EBITDA and net income of the combined company on a pro forma basis. This analysis assumed the completion of the merger and included certain interest cost savings associated with the assumed conversion of the ChipPAC convertible subordinated notes into ChipPAC Class A common stock. This analysis showed the following:

Using publicly available information, Morgan Stanley reviewed the terms of the following eight selected transactions announced between October 1, 2000 and January 23, 2004 involving companies in the semiconductor industry where the acquiror and/or target was a public company domiciled in the United States, the acquiror obtained control of the target, and the purchase consideration involved some form of stock component:

For each of these transactions, Morgan Stanley reviewed the ratios of the closing prices of the target’s shares divided by the corresponding closing prices of the acquiror’s shares over a 30-day period ending on the day prior to announcement of the acquisition. These ratios are referred to as the average exchange ratios. Morgan Stanley then analyzed the premiums implied by the transaction exchange ratios in such transactions over the 30-day average exchange ratio prior to announcement and the premium of the implied target share price in such transactions as of announcement over the closing target share prices one month prior to announcement and one day prior to announcement of the acquisition. The following table presents the range of premiums in these selected precedent transactions:

Morgan Stanley applied reference ranges of the premiums paid in these selected precedent transactions to the 30-day average exchange ratio and the closing prices of ChipPAC Class A common stock and STATS ADSs on January 7, 2004 and February 6, 2004, which resulted in the following implied ranges of prices for shares of ChipPAC Class A common stock and the following implied exchange ratio ranges:

Morgan Stanley then compared these implied price ranges with the implied per share price of $11.60 for ChipPAC Class A common stock based on the exchange ratio of 0.87 under the merger agreement and the closing price of the ChipPAC Class A common stock as of February 6, 2004. The following compares the range of exchange ratios implied by this analysis with the exchange ratio in the merger:

No company or transaction utilized in the precedent transaction analysis is identical to ChipPAC, STATS or the merger. In evaluating the precedent transactions, Morgan Stanley made judgments and assumptions with regard to industry performance, general business, economic, market and financial conditions and other factors, many of which are beyond the control of ChipPAC or STATS. These factors include the impact of competition on the business of ChipPAC or STATS and the industry generally, industry growth and the absence of any material adverse change in the financial condition and prospects of ChipPAC, STATS or the industry in general or the financial markets in general, all of which could affect the public trading value of the companies. Mathematical analyses, such as determining the average or median, is not in itself a meaningful method of using comparable transaction data.

Comparable company analysis examines a company’s trading performance relative to a group of publicly traded peer companies. Using publicly available information and estimates for ChipPAC, STATS and the peer companies, Morgan Stanley performed a comparable public company trading analysis by calculating and comparing (i) the multiple of share prices to 2004 estimated earnings, (ii) the multiple of aggregate value as of February 6, 2004 to estimated EBITDA for 2004, and (iii) the multiple of aggregate value as of February 6, 2004 to estimated sales for 2004. The group of selected peer companies consisted of the following:

In conducting its analysis, Morgan Stanley excluded certain outlier multiples. This analysis showed the following multiples:

Based on an analysis of the comparable public companies and the corresponding information for ChipPAC, Morgan Stanley applied the following reference multiples (which included a 40% control premium) for ChipPAC, which resulted in the following ranges of implied per share prices for the ChipPAC Class A common stock and the following ranges of implied exchange ratios:

No company utilized in the comparable company analysis is identical to ChipPAC. In evaluating the comparable companies, Morgan Stanley made judgments and assumptions with regard to industry performance, general business, economic, market and financial conditions and other factors, many of which are beyond the control of ChipPAC or STATS. These factors include the impact of competition on the business of ChipPAC or STATS and the industry generally, industry growth and the absence of any material adverse change in the financial condition and prospects of ChipPAC, STATS or the industry in general or the financial markets in general, all of which could affect the public trading value of the companies. Mathematical analyses, such as determining the average or median, is not in itself a meaningful method of using comparable company data.

Based on the combined market value of ChipPAC Class A common stock, STATS ordinary shares and STATS ADSs, Morgan Stanley analyzed the range of the ChipPAC stockholders’ implied percentage ownership of the combined company during the period from October 1, 2001 through February 4, 2004. For purposes of the analysis, Morgan Stanley assumed that the $200 million in aggregate principal amount of ChipPAC convertible subordinated notes issued during this period were converted into ChipPAC Class A common stock and added to the equity value of ChipPAC. The analysis showed a range of implied ownership by ChipPAC stockholders ranging from a low of 17.0% to a high of 49.1%, and a trailing 12-month average of 38.8% through February 4, 2004. The following compares the range of exchange ratios implied by this analysis with the exchange ratio in the merger:

Using financial information and estimates provided by the management of ChipPAC and STATS, Morgan Stanley analyzed the pro forma effect of the merger on STATS’ estimated financial performance for 2004. Based on the exchange ratio of 0.87 under the merger agreement, and implied multiples of aggregate value to estimated 2004 sales, aggregate value to estimated 2004 EBITDA and price to estimated 2004 earnings derived by Morgan Stanley using projections provided by the management of STATS and ChipPAC, the analysis showed that the merger would be accretive to STATS’ earnings per share before amortization and certain other charges, even if no synergies result from the merger. The analysis was based on the closing price of ChipPAC Class A common stock as of February 6, 2004, and assumed completion of the merger and the conversion of $50 million in aggregate principal amount of the ChipPAC 8% convertible subordinated notes.

Morgan Stanley also performed certain other reviews and analyses, including historical share price performance analysis. Morgan Stanley noted that due to the cyclical nature of the semiconductor industry and the difficulty in predicting medium-term to long-term cash flows of ChipPAC and STATS, discounted cash flow analysis would be of limited value in evaluating the exchange ratio under the merger agreement.

The preparation of a fairness opinion is a complex process that involves various determinations as to the most relevant methods of financial analyses and the application of these methods to the particular circumstances, and is not susceptible to a partial analysis or summary description. In arriving at its opinion, Morgan Stanley considered the results of all of its analyses as a whole and did not attribute any particular weight to any particular analysis or factor considered by it. Furthermore, selecting any portion of Morgan Stanley’s analyses without considering all of its analyses would create an incomplete view of the process underlying its analyses and the opinion. In addition, Morgan Stanley may have deemed various assumptions more or less probable than other assumptions, so that the ranges of valuations resulting from any particular analysis described above should not be taken to be its view of the actual value of ChipPAC, STATS or the combined company.

In performing its analyses, Morgan Stanley made numerous assumptions with respect to industry performance, general business and economic conditions and other matters, many of which are beyond the control of STATS, ChipPAC or the combined company. Any estimates contained in the analyses performed by Morgan Stanley are not necessarily indicative of actual values, which may be significantly more or less favorable than those suggested by these analyses. These analyses were prepared solely as a part of Morgan Stanley’s analysis of the fairness from a financial point of view of the exchange ratio under the merger agreement and were provided to the STATS board of directors in connection with the delivery of Morgan Stanley’s opinion to STATS. The analyses do not purport to be appraisals of value or to reflect the prices at which STATS or ChipPAC securities might actually be sold. In addition, as described above, Morgan Stanley’s opinion was one of the many factors taken into consideration by the STATS board of directors in its evaluation of the proposed merger. Consequently, the Morgan Stanley analyses as described above should not be viewed as determinative of the opinion of the STATS board of directors with respect to the value of STATS or ChipPAC or of whether the STATS board of directors would have been willing to agree to different consideration.

Morgan Stanley is an internationally recognized investment banking and advisory firm. Morgan Stanley, as part of its investment banking business, is regularly engaged in the valuation of businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements and valuations for corporate, estate and other purposes. Morgan Stanley has provided and may continue to provide investment banking services to STATS or ChipPAC in the future. In the ordinary course of its trading, brokerage, investment management and financing activities, Morgan Stanley and its affiliates may, at any time, have a long or short position in, and buy and sell the debt or equity securities and senior loans of STATS or ChipPAC for its account or the account of its customers.

STATS has agreed to pay Morgan Stanley for its financial advisory services in connection with the merger an estimated aggregate fee of up to approximately $6 million, which is contingent upon completion of the merger. STATS has also agreed, in its sole discretion and in good faith, to pay Morgan Stanley an additional incentive fee of up to $1 million for satisfactory execution of the merger. In addition, STATS has agreed to reimburse Morgan Stanley for out-of-pocket expenses incurred by Morgan Stanley in performing its services. STATS has also agreed to indemnify Morgan Stanley and its affiliates, their respective directors, officers, agents and employees and each person, if any, controlling Morgan Stanley or any of its affiliates against certain liabilities and expenses related to, arising out of or in connection with Morgan Stanley’s engagement. In the past, Morgan Stanley and its affiliates have provided financing services for STATS and have received fees for the rendering of these services. During the past two years, Morgan Stanley acted as a joint lead manager for a concurrent S$200 million equity offering by STATS and a US$115 million convertible bond offering by STATS on October 29, 2003. In connection with these services, STATS paid Morgan Stanley an aggregate of approximately $3.1 million.

In connection with Credit Suisse First Boston’s engagement, ChipPAC requested that Credit Suisse First Boston evaluate the fairness, from a financial point of view, to the holders of ChipPAC Class A common stock of the exchange ratio provided for in the merger. On February 9, 2004, at a meeting of the ChipPAC board of directors held to evaluate the merger, Credit Suisse First Boston rendered to the ChipPAC board of directors an oral opinion, which opinion was confirmed by delivery of a written opinion dated February 9, 2004, to the effect that, as of that date and based on and subject to the matters described in its opinion, the exchange ratio was fair to the holders of ChipPAC Class A common stock, from a financial point of view.

The full text of Credit Suisse First Boston’s written opinion, dated February 9, 2004, to the ChipPAC board of directors, which sets forth the procedures followed, assumptions made, matters considered and limitations on the review undertaken, is attached as Annex E and is incorporated into this document by reference. Holders of ChipPAC Class A common stock are encouraged to read this opinion carefully and

in its entirety. Credit Suisse First Boston’s opinion was provided to the ChipPAC board of directors in connection with its evaluation of the exchange ratio and relates only to the fairness, from a financial point of view, of the exchange ratio, does not address any other aspect of the proposed merger and does not constitute a recommendation to any stockholder as to any matters relating to the merger. The summary of Credit Suisse First Boston’s opinion in this document is qualified in its entirety by reference to the full text of the opinion.

In connection with its review, Credit Suisse First Boston did not assume any responsibility for independent verification of any such information and relied on such information being complete and accurate in all material respects. With respect to the financial forecasts for ChipPAC provided to or discussed with Credit Suisse First Boston by ChipPAC management, Credit Suisse First Boston was advised, and Credit Suisse First Boston assumed, that the forecasts had been reasonably prepared on bases reflecting the best currently available estimates and judgments of ChipPAC management as to the future financial performance of ChipPAC. As the ChipPAC board of directors was aware, STATS did not provide Credit Suisse First Boston with financial forecasts relating to STATS beyond calendar year 2004 and Credit Suisse First Boston therefore relied, at ChipPAC’s direction, upon the assessments of ChipPAC management as to those matters. Credit Suisse First Boston was advised, and assumed, that the financial forecasts relating to STATS with respect to calendar year 2004 provided to or discussed with Credit Suisse First Boston by STATS management and the financial forecasts relating to STATS beyond calendar year 2004 provided to or discussed with Credit Suisse First Boston by ChipPAC management were reasonably prepared on bases reflecting the best currently available estimates and judgments of the managements of STATS and ChipPAC, as the case may be, as to the future financial performance of STATS. In addition, Credit Suisse First Boston relied, with ChipPAC’s consent and without independent verification, on the assessments of the managements of ChipPAC and STATS as to:

Credit Suisse First Boston also assumed, with ChipPAC’s consent, that in the course of obtaining any regulatory or third party consents, approvals or agreements in connection with the merger, no limitations, restrictions or conditions would be imposed that would have an adverse effect on ChipPAC, STATS or the

contemplated benefits of the merger and that the merger would be consummated in accordance with the terms of the merger agreement and other relevant documents without waiver, modification or amendment of any material term, condition or agreement contained in the merger agreement. Representatives of ChipPAC advised Credit Suisse First Boston, and Credit Suisse First Boston therefore assumed, that the merger agreement, when executed, would conform to the draft reviewed by Credit Suisse First Boston in all respects material to its analyses.

Credit Suisse First Boston was not requested to make, and has not made, an independent evaluation or appraisal of the assets or liabilities, contingent or otherwise, of ChipPAC or STATS, and Credit Suisse First Boston was not furnished with any such evaluations or appraisals. Credit Suisse First Boston’s opinion was necessarily based on information made available to it as of the date of the opinion, and financial, economic, market and other conditions as they existed and could be evaluated on the date of the opinion. Credit Suisse First Boston did not express any opinion as to the actual value of STATS ADSs when issued to holders of ChipPAC Class A common stock in the merger or the prices at which STATS ADSs or STATS ordinary shares would trade at any time. In connection with its engagement, Credit Suisse First Boston was not requested to, and it did not, solicit third party indications of interest in acquiring all or any part of ChipPAC. Credit Suisse First Boston’s opinion did not address the relative merits of the merger as compared to other business strategies that may be available to ChipPAC, and it did not address the underlying business decision of ChipPAC to engage in the merger. Except as described above, ChipPAC imposed no other limitations on Credit Suisse First Boston with respect to the investigations made or procedures followed in rendering the opinion.

In preparing its opinion to the ChipPAC board of directors, Credit Suisse First Boston performed a variety of financial and comparative analyses, including those described below. The summary of Credit Suisse First Boston’s analyses described below is not a complete description of the analyses underlying Credit Suisse First Boston’s opinion. The preparation of a financial opinion is a complex process involving various determinations as to the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances and, therefore, a financial opinion is not readily susceptible to partial analysis or summary description. In arriving at its opinion, Credit Suisse First Boston made qualitative judgments as to the significance and relevance of each analysis and factor that it considered. Credit Suisse First Boston arrived at its ultimate opinion based on the results of all analyses undertaken by it and assessed as a whole and did not draw, in isolation, conclusions from or with regard to any one factor or method of analysis. Accordingly, Credit Suisse First Boston believes that its analyses must be considered as a whole and that selecting portions of its analyses and factors or focusing on information presented in tabular format, without considering all analyses and factors or the narrative description of the analyses, could create a misleading or incomplete view of the processes underlying its analyses and opinion.

In its analyses, Credit Suisse First Boston considered industry performance, general business, economic, market and financial conditions and other matters, many of which are beyond the control of ChipPAC and STATS. No company, transaction or business used in Credit Suisse First Boston’s analyses as a comparison is identical to ChipPAC or STATS or the proposed merger, and an evaluation of the results of those analyses is not entirely mathematical. Rather, the analyses involve complex considerations and judgments concerning financial and operating characteristics and other factors that could affect the acquisition, public trading or other values of the companies, business segments or transactions analyzed. The estimates contained in Credit Suisse First Boston’s analyses and the ranges of valuations resulting from any particular analysis are not necessarily indicative of actual values or predictive of future results or values, which may be significantly more or less favorable than those suggested by the analyses. In addition, analyses relating to the value of businesses or securities do not purport to be appraisals or to reflect the prices at which businesses or securities actually may be sold. Accordingly, Credit Suisse First Boston’s analyses and estimates are inherently subject to substantial uncertainty.

Credit Suisse First Boston’s opinion and financial analyses were only one of many factors considered by the ChipPAC board of directors in its evaluation of the proposed merger and should not be viewed as determinative of the views of the ChipPAC board of directors or management with respect to the merger or the exchange ratio.

The following is a summary of the material financial analyses underlying Credit Suisse First Boston’s opinion dated February 9, 2004 delivered to the ChipPAC board of directors in connection with the merger. The financial analyses summarized below include information presented in tabular format. In order to fully understand Credit Suisse First Boston’s financial analyses, the tables must be read together with the text of each summary. The tables alone do not constitute a complete description of the financial analyses. Considering the data in the tables below without considering the full narrative description of the financial analyses, including the methodologies and assumptions underlying the analyses, could create a misleading or incomplete view of Credit Suisse First Boston’s financial analyses.

Credit Suisse First Boston compared financial, operating and stock market data of ChipPAC, STATS and the following five publicly traded companies in the semiconductor assembly and test industry:

Credit Suisse First Boston reviewed enterprise values, calculated as equity value plus net debt and minority interests, as multiples of revenue and earnings before interest, taxes, depreciation and amortization, commonly referred to as EBITDA, for calendar years 2003 and 2004. Credit Suisse First Boston also reviewed per share equity values of the selected companies as a multiple of earnings per share, commonly referred to as EPS, for calendar years 2003 and 2004. Estimated financial data for the selected companies were based on publicly available research analysts’ estimates. Estimated financial data for ChipPAC were based on internal estimates of ChipPAC management and estimated financial data for STATS were based on internal estimates of STATS management. All multiples were based on closing stock prices on February 6, 2004. Credit Suisse First Boston derived implied exchange ratio reference ranges by applying ranges of selected revenue, EBITDA and EPS multiples derived from the financial data observed for the selected companies, respectively, to calendar year 2003 and estimated calendar year 2004 revenue and EBITDA and calendar year 2004 estimated unlevered net income, defined as operating income less taxes, for ChipPAC and STATS, which yielded implied exchange ratio reference ranges based on calendar year 2003 revenue and EBITDA of 0.593x to 0.655x and 0.497x to 0.541x, respectively, and implied exchange ratio reference ranges based on estimated calendar year 2004 revenue, EBITDA and unlevered net income of 0.650x to 0.711x, 0.623x to 0.648x and 1.005x to 1.027x, respectively. Calendar year 2003 EPS multiples of the selected companies were not considered meaningful given that both ChipPAC and STATS had negative net income in that calendar year. This analysis indicated the following overall implied exchange ratio reference range, as compared to the exchange ratio provided for in the merger:

Credit Suisse First Boston reviewed the purchase prices and implied transaction values of the following 11 selected transactions involving companies in the semiconductor assembly and test industry:

Credit Suisse First Boston compared transaction values in the selected transactions as multiples of latest 12 months revenue and EBITDA. All multiples for the selected transactions were based on information available at the time of announcement of the relevant transaction. Credit Suisse First Boston derived implied exchange ratio reference ranges by applying ranges of selected multiples derived from the financial data observed for the selected transactions to corresponding financial data of ChipPAC for calendar year 2003 and utilizing the closing per ADS price of STATS on February 6, 2004, which yielded implied exchange ratio reference ranges based on revenue and EBITDA of 0.258x to 0.569x and 0.089x to 0.340x, respectively. This analysis indicated the following overall implied exchange ratio reference range, as compared to the exchange ratio provided for in the merger:

Credit Suisse First Boston calculated the estimated present value of the stand-alone, unlevered, after-tax free cash flows that each of ChipPAC and STATS could generate for calendar years 2004 through 2008. Estimated financial data for ChipPAC were based on internal estimates of ChipPAC management. Estimated financial data for STATS were based on internal estimates of STATS management for calendar year 2004 and extrapolated by ChipPAC management for calendar years 2005 through 2008. Credit Suisse First Boston applied a range of EBITDA terminal value multiples of 7.0x to 10.0x to ChipPAC’s and STATS’ estimated EBITDA for calendar year 2008. The present value of the cash flows and terminal values were calculated using discount rates ranging from 13.0% to 16.0%. This analysis indicated the following implied exchange ratio reference range, as compared to the exchange ratio provided for in the merger:

Credit Suisse First Boston compared the relative contributions of ChipPAC and STATS to the combined company’s pro forma revenue, gross profit and EBITDA for calendar years 2003 and 2004 and estimated net income for calendar year 2004. Estimated financial data for ChipPAC were based on internal estimates of ChipPAC management and estimated financial data for STATS were based on internal estimates of STATS management. Credit Suisse First Boston computed the fully diluted equity ownership percentages of ChipPAC’s stockholders in the combined company implied by ChipPAC’s relative contribution for each operating metric observed, in each case adjusted to reflect net debt and minority interests of ChipPAC and STATS, and the exchange ratios implied by those ownership percentages. This analysis indicated the following implied exchange ratio reference range, as compared to the exchange ratio provided for in the merger:

Credit Suisse First Boston reviewed the potential pro forma effect of the merger on STATS’ calendar year 2004 estimated cash earnings per ADS without giving effect to potential cost savings and other synergies that could result from the merger. Estimated financial data for ChipPAC were based on internal estimates of ChipPAC management and estimated financial data for STATS were based on internal estimates of STATS management. Based on the exchange ratio of 0.870x, this analysis indicated that the merger could be accretive to STATS’ calendar year 2004 estimated cash earnings per ADS. The actual results achieved by the combined company may vary from these projected results and the variations may be material.

In the course of preparing its opinion, Credit Suisse First Boston also reviewed and considered other information and data, including:

Credit Suisse First Boston has acted as ChipPAC’s exclusive financial advisor in connection with the merger. ChipPAC selected Credit Suisse First Boston based on Credit Suisse First Boston’s experience and reputation, and its familiarity with ChipPAC and its business. Credit Suisse First Boston is an internationally recognized investment banking firm and is regularly engaged in the valuation of businesses and securities in connection with mergers and acquisitions, leveraged buyouts, negotiated underwritings, competitive biddings, secondary distributions of listed and unlisted securities, private placements and valuations for corporate and other purposes.

Credit Suisse First Boston and its affiliates in the past have provided and may in the future provide investment banking and financial services to ChipPAC and STATS unrelated to the merger, for which services Credit Suisse First Boston and its affiliates have received, and would expect to receive, compensation. In 2002, Credit Suisse First Boston acted as sole bookrunner and lead managing underwriter for two public offerings of ChipPAC Class A common stock. From January 2002 to May 2003, Credit Suisse First Boston and its affiliates also provided investment banking and financial services to ChipPAC in connection with certain amendments to ChipPAC’s bank facility and ChipPAC Class A common stock repurchases undertaken by ChipPAC. Credit Suisse First Boston and its affiliates received an aggregate of approximately $4.7 million for such services. In the ordinary course of business, Credit Suisse First Boston and its affiliates may actively trade the securities of ChipPAC and STATS for their own accounts and for the accounts of customers and, accordingly, may at any time hold long or short positions in those securities.

ChipPAC has agreed to pay Credit Suisse First Boston for its financial advisory services in connection with the merger, including the rendering of its opinion, an estimated aggregate fee of approximately $21 million, approximately $20 million of which is contingent upon completion of the merger. ChipPAC also has agreed to reimburse Credit Suisse First Boston for its out-of-pocket expenses, including fees and expenses of legal counsel and any other advisor retained by Credit Suisse First Boston, and to indemnify Credit Suisse First Boston and related parties against liabilities, including liabilities under the federal securities laws, arising out of its engagement.

During the due diligence investigations that each of STATS and ChipPAC conducted on the other prior to the signing of the merger agreement, STATS and ChipPAC exchanged certain forecasts for their respective 2004 operating results. The forecasts provided by STATS (the STATS forecasts) to ChipPAC and its financial advisor were prepared by management of STATS in November 2003. The forecasts provided by ChipPAC (the ChipPAC forecasts) to STATS and its financial advisor were prepared by management of ChipPAC in January 2004. Neither the STATS forecasts nor the ChipPAC forecasts were prepared with a view to public disclosure and are included in this document only because they were provided to the other party and its financial advisor. STATS does not in the ordinary course publicly disclose projections of future operating results, other than providing general guidance in its quarterly earnings releases for expected revenues and utilization for the next quarter and expected capital expenditures for the full year. Similarly, ChipPAC only provides, in its quarterly earnings releases, general guidance for the full year revenue and a range for expected revenue and net income per share for the next quarter. STATS and ChipPAC do not publish forecasts beyond this limited guidance due to the significant volatility in the semiconductor and semiconductor assembly and test services industries and the resulting difficulties in making forecasts for results of operations for future periods.

The STATS forecasts and the ChipPAC forecasts were prepared by the management of STATS and ChipPAC, respectively, based on a variety of estimates and assumptions about STATS and ChipPAC, respectively, on a stand-alone basis. Certain key assumptions underlying these forecasts are summarized below. These assumptions may not be accurate, may not be realized, and are inherently subject to a wide variety of significant business, economic and competitive risks and uncertainties, all of which are difficult to predict and most of which are beyond the control of STATS and ChipPAC. Such risks and uncertainties could cause actual results to differ materially from those contained in the forecasts. Accordingly, there can be no assurance that the forecasts are indicative of the future performance of either of the companies or that actual results will not differ materially from those presented in the forecasts. STATS and ChipPAC management believe that the semiconductor industry is highly volatile and that it is particularly difficult to forecast future financial performance in the semiconductor industry.

STATS and ChipPAC also note that the STATS forecasts and the ChipPAC forecasts did not take into account any effects on the business or results of operations (whether positive or negative) of STATS or ChipPAC as a result of the announcement of the proposed merger. In addition, the STATS forecasts and the ChipPAC

forecasts do not reflect any changes in general business and economic conditions or any other event that has occurred and that was not anticipated at the time the STATS forecasts and the ChipPAC forecasts were prepared. Since the STATS forecasts and the ChipPAC forecasts were prepared, each of STATS and ChipPAC has announced results of operation for the year ended December 31, 2003 and for the quarter ended March 31, 2004. See “Summary Historical Financial Data of STATS” on page 20, “Summary Historical Financial Data of ChipPAC” on page 22 and the historical consolidated financial statements of STATS and ChipPAC incorporated by reference in this document. The STATS forecasts and ChipPAC forecasts are presented in this document for the limited purpose of giving shareholders access to the financial forecasts that were made available to ChipPAC and STATS, respectively, and their respective financial advisor in connection with their due diligence investigations prior to the signing of the merger agreement.

The STATS forecasts forecasted net sales and gross profit for STATS for the year ended December 31, 2004 of $548.9 million and $121.7 million, respectively. Net income and fully diluted earnings per STATS ADS for the year ended December 31, 2004 were forecasted at $40.1 million and $0.37 per STATS ADS, respectively. The principal assumptions underlying the STATS forecast were: (i) projected growth in STATS revenue assuming that (a) the expected year-over-year growth rate of the outsourced semiconductor test and assembly market would exceed the growth rate projected for the semiconductor industry as published in industry reports, (b) increased overall demand projections by STATS’ customers (where available) will be met, (c) STATS will proceed with production of STATS’ new programs and new customer wins and (d) average selling price erosion would be consistent with STATS’ historical norms and (ii) overall improvement in STATS’ cost structure, which would result from, among other things, (a) material price increases and decreases for the relevant commodity type, (b) labor cost increases being offset by overall productivity gains, (c) increases in overhead costs being spread over a greater volume of services provided, and (d) improved manufacturing productivity through improved utilization and improved processes, and which would be partially offset by effects of foreign currency exchange rates.

The ChipPAC forecasts forecasted net sales and gross profit for ChipPAC for the year ended December 31, 2004 of $617.7 million and $138.9 million, respectively. Net income and fully diluted earnings per share of ChipPAC Class A common stock (excluding merger related costs) for the year ended December 31, 2004 were forecasted at $35.0 million and $0.35 per share of ChipPAC Class A common stock, respectively. The principal assumptions underlying the ChipPAC forecasts were that: (i) the higher volume of business and demand in the most recently preceding quarter ended December 31, 2003 would be more representative of each of the quarters in 2004 than the earlier quarters in 2003, (ii) semiconductor industry revenue would increase at approximately 20% (as reported by the Semiconductor Industry Association and The Gartner Group), (iii) outsourcing assembly and test would grow faster than the underlying semiconductor growth rate (as reported by Dataquest), (iv) average selling price erosion would be consistent with ChipPAC’s historical norms, (v) ChipPAC’s confirmed new programs would commence production, (vi) ChipPAC’s cost structure would improve overall, as a result of a combination of factors, including (a) new design wins, (b) the increased price of gold, (c) foreign currency exchange rates having an overall negative effect, (d) material price increases and decreases based on commodity type, (e) labor cost increases being offset by overall productivity gains, (f) increased overhead costs being spread over greater volume and (g) improved manufacturing productivity.

Certain matters discussed in this document, including, but not limited to the STATS forecasts and the ChipPAC forecasts, are forward-looking statements that involve risks and uncertainties. There can be no assurance that any of the STATS forecasts or the ChipPAC forecasts will be realized and the actual results for 2004 may vary materially from those described above.

In addition, the STATS forecasts and the ChipPAC forecasts were not prepared with a view to public disclosure or compliance with published guidelines of the SEC or the guidelines established by the American Institute of Certified Public Accountants regarding projections, which would require a more complete presentation of data than provided above. Neither STATS’ nor ChipPAC’s independent accountants have examined or compiled any of the STATS forecasts or the ChipPAC forecasts or expressed any conclusion or provided any form of assurance with respect to the STATS forecasts or the

ChipPAC forecasts and accordingly assume no responsibility for the STATS forecasts or the ChipPAC forecasts. The STATS forecasts and the ChipPAC forecasts are included in this document only because such information was provided to ChipPAC and STATS, respectively, and their respective financial advisors. The inclusion of the STATS forecasts and the ChipPAC forecasts in this document should not be regarded as an indication that any of STATS or ChipPAC or their respective advisors considered or consider the STATS forecasts or the ChipPAC forecasts to be an accurate prediction of future events and the STATS forecasts and the ChipPAC forecasts should not be relied on as such. None of STATS, ChipPAC or any other of their representatives or advisors has made or makes any representation to any person regarding the ultimate performance of STATS or ChipPAC compared to the information contained in the STATS forecasts or the ChipPAC forecasts, respectively. None of STATS, ChipPAC or their respective officers and directors intends to update or otherwise revise the STATS forecasts or the ChipPAC forecasts to reflect the occurrence of future events even in the event that any or all of the assumptions underlying the STATS forecasts or the ChipPAC forecasts are shown to be in error. Actual results may vary materially from those reflected in the STATS forecasts or the ChipPAC forecasts.

When considering the recommendations of the STATS board of directors, STATS shareholders should be aware that the directors and officers of STATS have interests in the merger and have arrangements that are different from, or are in addition to, those of STATS shareholders generally. The STATS board of directors and the ChipPAC board of directors were aware of these interests, to the extent they existed at the time, and considered them, among other matters, in approving the merger, the merger agreement and the transactions contemplated by the merger agreement.

Covenants of the executives. The executive officers are subject to a confidentiality provision under the employment agreements precluding them from using or disclosing confidential information of STATS.

Termination. STATS may terminate the employment agreements with its executive officers without cause upon three months’ notice or payment in lieu of notice.

When considering the recommendation of the ChipPAC board of directors, ChipPAC stockholders should be aware that the directors and officers of ChipPAC have interests in the merger and have arrangements that are different from, or in addition to, those of ChipPAC stockholders generally. The STATS board of directors and the ChipPAC board of directors were aware of these interests, to the extent they existed at the time, and considered them, among other matters, in approving the merger, the merger agreement and the transactions contemplated by the merger agreement.

ChipPAC stock beneficially owned by ChipPAC executive officers and directors. At the close of business on June 16, 2004, the executive officers and directors of ChipPAC beneficially owned in the aggregate approximately 17,906,326 of the outstanding shares of ChipPAC Class A common stock, collectively representing 18.2% of the total outstanding voting power of ChipPAC on that date. Certain directors and Mr. McKenna, the President and Chief Executive Officer of ChipPAC and Chairman of the ChipPAC board of directors, have agreed to vote all of the shares of ChipPAC Class A common stock owned of record by them at the ChipPAC special meeting in favor of the approval and adoption of the merger agreement and approval of the merger.

ChipPAC stock options. Pursuant to the merger agreement and the terms of ChipPAC’s various stock plans, each holder, including executive officers and directors of ChipPAC, of a ChipPAC option granted under the ChipPAC 1999 plan and ChipPAC 2000 plan, that is outstanding and unexercised immediately prior to the effective time of the merger will be entitled to receive STATS substitute options to purchase 8.7 STATS ordinary shares for each share of ChipPAC Class A common stock subject to a ChipPAC option held by the option holder on substantially the same terms and conditions as were applicable to the ChipPAC stock option. Upon exercise of a STATS substitute option, the holder of a STATS substitute option may elect to receive, in lieu of STATS ordinary shares, a number of STATS ADSs equal to the number of STATS ordinary shares subject to such STATS substitute option, divided by ten and rounded down to the nearest whole STATS ADS. Based on ChipPAC stock options outstanding as of June 16, 2004:

Separation agreement with Mr. McKenna. STATS, ChipPAC and Mr. McKenna entered into a separation agreement, which will not become effective until the consummation of the merger, pursuant to which Mr. McKenna has agreed to resign from his position as President and Chief Executive Officer of ChipPAC and to relinquish his position as a member of the ChipPAC board of directors.

STATS has agreed to nominate Mr. McKenna to serve, effective as of the consummation of the merger, as Vice Chairman of the STATS board of directors for a term to continue until December 31, 2004. Mr. McKenna is required to resign as a member, and from his position as Vice Chairman, of the STATS board of directors on and effective as of December 31, 2004.

In consideration of covenants agreed to by Mr. McKenna under his separation agreement, including his resignation from his position as President and Chief Executive Officer of ChipPAC and his execution and delivery of a general release against ChipPAC, STATS and their affiliates, Mr. McKenna will be eligible to receive the following payments and benefits from ChipPAC, subject to the terms and conditions of the separation agreement:

Accordingly, under and subject to the terms and conditions of his separation agreement, if the merger is completed, Mr. McKenna will be eligible to receive cash payments aggregating approximately $2.21 million and accelerated vesting in full of unvested stock options held by Mr. McKenna (which, as of June 16, 2004, represented approximately 679,800 shares of ChipPAC Class A common stock).

Under his separation agreement, Mr. McKenna has agreed not to compete with STATS or ChipPAC, not to solicit any employees of ChipPAC and not to interfere with any business relations of STATS or ChipPAC for a period of 24 months immediately following the completion of the merger.

The separation agreement with Mr. McKenna will, upon its effectiveness, supersede his existing employment agreement with ChipPAC. Pursuant to Mr. McKenna’s existing employment agreement, if ChipPAC terminates his employment without “cause” or if Mr. McKenna resigns for “good reason” (both of the foregoing terms as defined in his existing employment agreement), Mr. McKenna will be entitled to the following payments and benefits:

“Good reason” under Mr. McKenna’s employment agreement includes a situation where Mr. McKenna ceases to serve as President and Chief Executive Officer of ChipPAC and where he ceases to report to the ChipPAC board of directors.

The cash payments Mr. McKenna would be eligible to receive under his existing employment agreement if his employment is terminated without cause or if he resigns for good reason aggregates approximately $976,000.

Employment agreement with Michael G. Potter. On March 17, 2004, after the signing of the merger agreement and announcement of the proposed merger, STATS, ChipPAC and Mr. Michael G. Potter, the Acting Chief Financial Officer of ChipPAC, entered into an employment agreement, which will not become effective unless and until the merger is consummated. The employment agreement with Mr. Potter will, upon its effectiveness, supersede his existing employment agreement with ChipPAC.

Position and term. Mr. Potter will serve as the Chief Financial Officer of the combined company for a term of five years.

Compensation. Under his employment agreement, Mr. Potter will receive an annual base salary in the amount of $217,000. He will also be eligible to earn an annual cash bonus during each year of the five-year term and a retention bonus payable over the two-year period commencing on the day the merger is consummated. The amount of the annual bonus will be based on Mr. Potter’s performance and will be determined at the end of the applicable incentive compensation plan year. The amount of the retention bonus is equal to $217,000. The retention bonus is payable at the rate of 25% of the bonus amount on the first payroll date following the consummation of the merger, 25% at the end of the first year following consummation of the merger, and 50% at the end of the second year following consummation of the merger. Subject to approval of the compensation committee of the STATS board of directors, Mr. Potter will be granted under the STATS 1999 option plan an option to purchase a number of STATS ordinary shares as determined by the compensation committee on the date of grant having a per share exercise price equal to the fair market value of the STATS ordinary shares on the date of grant. Mr. Potter will also be entitled to certain expatriate and repatriation benefits in connection with the relocation of Mr. Potter and his immediate family to Singapore.

Employment termination. If (1) the combined company terminates the employment of Mr. Potter without cause, (2) he resigns for good reason during the two years following the consummation of the merger or (3) he resigns for any reason during the three subsequent years, he will be entitled to payment of the unpaid portion of his retention bonus, his prorated annual incentive bonus, continuation of his salary for a maximum of six months following the date of termination, payment for the cost of maintaining COBRA coverage continuation during a maximum period of six months, automatic full vesting and immediate exercisability of his options outstanding on the date of the termination and, if Mr. Potter’s place of employment is located outside the United States on the date of the termination, payment of the cost to repatriate Mr. Potter and his immediate family to the United States.

If Mr. Potter and the combined company mutually agree to terminate Mr. Potter’s employment during the two-year period following the consummation of the merger, Mr. Potter will be entitled to a prorated amount of the unpaid portion of his retention bonus, the prorated portion of his annual incentive bonus, continuation of his salary for a maximum of six months following the date of termination, payment for the cost of maintaining COBRA coverage continuation during a maximum period of six months and full vesting and immediate exercisability of his options outstanding as of the date of termination.

In the event of Mr. Potter’s death or in the case of termination of his employment due to his disability during the term of his agreement, Mr. Potter or his estate, as applicable, will be entitled to payment of any unpaid prorated portion of the retention bonus, the prorated portion of his annual incentive bonus, full vesting and immediate exercisability of his options outstanding as of the date of the termination or death, as applicable, and, if Mr. Potter’s place of employment is located outside the United States on the date of termination or death, as applicable, payment of the cost to repatriate Mr. Potter and his immediate family to the United States.

Covenants. Pursuant to his employment agreement, Mr. Potter has agreed not to use or disclose any confidential information of STATS or its affiliates and to be bound during the 18 months following the consummation of the merger by a covenant not to compete with the combined company and during the 18 months following the termination of his employment by a covenant not to solicit the employees or business relations of the combined company.

ChipPAC, Inc. Employee Retention and Severance Plan. ChipPAC has established the ChipPAC employee retention plan in connection with and conditioned upon the consummation of the merger, under which all active and full-time employees, including executive officers, of ChipPAC are eligible to be selected to receive a retention or severance payment or both, based upon the participant’s continuing employment, in the case of a participant receiving a retention payment, or the participant’s termination in connection with the consummation of the merger, in the case of a participant receiving a severance payment. The maximum aggregate amount payable under the ChipPAC employee retention plan may in no event exceed $5 million. The terms and conditions to which the retention and severance payments are subject, including the amounts payable under the plan, will be determined by the plan administrator, in consultation with senior management of ChipPAC. Certain retention payments are payable over a two-year period following the completion of the merger based on the participant’s continued employment through the payment dates. The retention and severance payments vary in amount, ranging from the amount of severance payable under the participant’s original employment offer letter, to a specific number of weeks of base pay not to exceed 78 weeks of base pay, to two weeks’ base pay for each full year of employment completed with ChipPAC as of the termination date, to a percentage of a participant’s base salary not to exceed an amount equal to two times base salary.

Under the ChipPAC employee retention plan, ChipPAC stock options held by participants whose employment is expected to be terminated at or shortly after closing, other than options granted on or after January 1, 2004, become fully exercisable upon the consummation of the merger. All ChipPAC stock options will be substituted with STATS substitute options on substantially the same terms and conditions as were applicable to the ChipPAC stock options replaced. In addition, certain participants under the ChipPAC employee retention plan whose employment is terminated without cause or by the participant for good reason will be entitled during a specified period to reimbursement for medical and dental continuation coverage.

The executive officers of ChipPAC are eligible to participate in the ChipPAC employee retention plan to the extent that they have not entered into separate arrangements of a similar nature in connection with the merger. ChipPAC has entered into retention agreements with each of Mr. Krakauer and Ms. McCall under the terms and conditions of the ChipPAC employee retention plan. These retention agreements, upon their effectiveness, will supersede the respective existing employment agreements with these executive officers.

On April 18, 2004, after the signing of the merger agreement and announcement of the proposed merger, ChipPAC entered into a retention agreement with Mr. Krakauer under and subject to the provisions of the ChipPAC employee retention plan. Mr. Krakauer’s retention agreement will be rendered void if the merger is not consummated. Pursuant to Mr. Krakauer’s retention agreement and subject to the terms and conditions of the ChipPAC employee retention plan, he will be entitled to the following payments and benefits if he continues his employment with ChipPAC through the later of June 30, 2004 and the closing of the merger, or earlier, if ChipPAC terminates Mr. Krakauer’s employment without “cause” or if he resigns for “good reason” (as these terms are defined in the ChipPAC employee retention plan) prior to his scheduled termination date:

Accordingly, under and subject to the terms and conditions of his retention agreement and the ChipPAC employee retention plan, if the merger is completed, Mr. Krakauer will be eligible to receive cash payments aggregating approximately $387,400 and accelerated vesting in full of unvested stock options granted to him prior to January 1, 2004 (which, as of June 16, 2004, represented approximately 141,000 shares of ChipPAC Class A common stock).

Mr. Krakauer’s retention agreement will, upon its effectiveness, supersede his existing employment agreement. Under his existing employment agreement, if ChipPAC terminates Mr. Krakauer’s employment without cause, he will be eligible to receive severance in an amount equal to eight months of his base salary and a prorated bonus for the fiscal year in which the termination occurs, provided that ChipPAC achieved its targets such that a bonus were paid out to other eligible participants for the applicable performance period. Accordingly, under his existing employment agreement, if ChipPAC terminates Mr. Krakauer’s employment without cause, whether or not the merger is completed, Mr. Krakauer will be eligible to receive cash payments aggregating approximately $293,300.

On May 11, 2004, after the signing of the merger agreement and announcement of the proposed merger, ChipPAC entered into a retention agreement with Ms. McCall under and subject to the provisions of the ChipPAC employee retention plan. Ms. McCall’s retention agreement will be rendered void if the merger is not consummated. Pursuant to Ms. McCall’s retention agreement and subject to the terms and conditions of the ChipPAC employee retention plan, she will be entitled to the following payments and benefits if she continues her employment with ChipPAC through the 90th day following the closing of the merger, or earlier, if ChipPAC terminates her employment without “cause” or if she resigns for “good reason” (as those terms are defined in the ChipPAC employee retention plan) prior to her scheduled termination date:

Accordingly, under and subject to the terms and conditions of her retention agreement and the ChipPAC employee retention plan, Ms. McCall will be eligible to receive cash payments aggregating approximately $477,400 and accelerated vesting in full of unvested stock options granted to her prior to January 1, 2004 (which, as of June 16, 2004, represented approximately 96,000 shares of ChipPAC Class A common stock).

Ms. McCall’s retention agreement will, upon its effectiveness, supersede her existing employment agreement. Ms. McCall’s existing employment agreement provides that if ChipPAC terminates Ms. McCall’s employment without cause or if she is subject to an involuntary or constructive termination within six months of a change in control, Ms. McCall will be eligible to receive a severance payment equal to eight months of her base salary and a prorated bonus for the fiscal year in which the termination occurs, provided that ChipPAC achieved its targets such that a bonus is paid out to other eligible participants for the applicable performance period. Ms. McCall’s existing employment agreement also provides for accelerated vesting in full of an unvested stock option held by Ms. McCall (which, as of June 16, 2004, represented approximately 30,000 shares of ChipPAC Class A common stock) upon completion of the merger. Accordingly, under Ms. McCall’s existing employment agreement, if the merger is not completed and ChipPAC terminates Ms. McCall’s employment without cause or upon an involuntary or constructive termination of Ms. McCall’s employment following completion of the merger, Ms. McCall will be eligible to receive cash payments of up to approximately $240,000.

The merger will be completed when all of the conditions to completion of the merger are satisfied or waived, including the approval by the shareholders of STATS of the issuance of STATS ordinary shares in the merger and the other matters related to the merger and the adoption and approval of the merger agreement and approval of the merger by the stockholders of ChipPAC. The merger will become effective upon the filing of the certificate of merger with the Secretary of State of the State of Delaware.

When the merger is completed, STATS’ exchange agent will mail to former ChipPAC stockholders a letter of transmittal and instructions for use in surrendering ChipPAC stock certificates in exchange for STATS ADSs. When former ChipPAC stockholders deliver their ChipPAC stock certificates to the exchange agent along with an executed letter of transmittal and any other required documents, the ChipPAC stock certificates will be canceled and former ChipPAC stockholders will be entitled to receive the number of full STATS ADSs to which they are entitled under the merger agreement. They will also receive payment in cash, without interest, in lieu of any fractional STATS ADS that would have been otherwise issuable to them in the merger (based on the price obtained by STATS’ exchange agent when selling the aggregate of all fractional STATS ADSs on Nasdaq).

STATS will only issue to ChipPAC stockholders the STATS ADSs or a check in lieu of a fractional STATS ADS in the name in which the surrendered ChipPAC stock certificate is registered. If ChipPAC stockholders wish to have their certificates issued in another name they must present the exchange agent with all documents required to show and effect the unrecorded transfer of ownership and show that they paid any applicable stock transfer taxes.

ChipPAC stockholders should not submit their ChipPAC stock certificates for exchange until they receive the transmittal instructions and a form of letter of transmittal from the exchange agent.

ChipPAC stockholders are not entitled to receive any dividends or other distributions on STATS ADSs until the merger is completed and they have surrendered their ChipPAC stock certificates in exchange for STATS ADSs.

Subject to the effect of applicable laws, promptly following surrender of ChipPAC stock certificates and the issuance of the corresponding STATS ADSs, ChipPAC stockholders will be paid the amount of dividends or other distributions, without interest, with a record date after the completion of the merger which were previously paid with respect to their whole STATS ADSs.

The following discussion constitutes the opinion of Shearman & Sterling LLP regarding the material U.S. federal income tax consequences of the merger to U.S. Holders of ChipPAC Class A common stock who will exchange their ChipPAC Class A common stock for STATS ADSs, and the material U.S. federal income tax consequences to U.S. Holders of the ownership and disposition of STATS ADSs. The discussion under the subsection herein entitled “—The merger” below also constitutes the opinion of Kirkland & Ellis LLP regarding the material U.S. federal income tax consequences of the merger to U.S. Holders of ChipPAC Class A common stock who will exchange their ChipPAC Class A common stock for STATS ADSs. The opinions of Shearman & Sterling LLP and Kirkland & Ellis LLP will be filed as exhibits to the registration statement, of which this document forms a part, filed with the SEC on Form F-4 prior to the time the registration statement is declared effective by the SEC. The discussion is based on the Internal Revenue Code, Treasury regulations under the Internal Revenue Code, administrative rulings and judicial decisions, all as in effect as of the date of this document and all of which are subject to change (possibly with retroactive effect) and to differing interpretations. Any change in the foregoing could affect the continuing validity of the U.S. federal income tax consequences described in this document. This discussion is not binding on the IRS, and there can be no assurance that the IRS will not disagree with or challenge any of the conclusions described below.

This discussion applies only to holders of ChipPAC Class A common stock and holders of STATS ADSs after the merger who are U.S. Holders. For purposes of this discussion, the term “U.S. Holder” means:

If a partnership holds ChipPAC Class A common stock, the U.S. federal income tax treatment of a partner in the partnership generally will depend on the status of the partner and the activities of the partnership. Partners of partnerships that hold ChipPAC Class A common stock should consult their tax advisors regarding the U.S. federal income tax consequences to them of the merger.

This discussion is not a comprehensive description of all the tax consequences that may be relevant to holders of ChipPAC Class A common stock. It applies only to holders of ChipPAC Class A common stock that hold their ChipPAC Class A common stock, and will hold the STATS ADSs that they receive in the merger, as capital assets within the meaning of Section 1221 of the Internal Revenue Code. No attempt has been made to address all aspects of U.S. federal income taxation that may be relevant to a particular holder of ChipPAC Class A common stock in light of its particular circumstances or to holders of ChipPAC Class A common stock subject to special treatment under the U.S. federal income tax laws, including:

In addition, this discussion does not address any alternative minimum tax, U.S. federal estate and gift tax, or any state, local or foreign tax consequences of the merger. It does not address the tax consequences of any transaction other than the merger, including transactions completed prior to or after the merger (whether or not such transactions are in connection with the merger).

In general, for U.S. federal income tax purposes, ownership of STATS ADSs will be treated as ownership of the underlying STATS ordinary shares. Deposits and withdrawals of ordinary shares in exchange for STATS ADSs will not be subject to U.S. federal income taxation.

EACH HOLDER OF CHIPPAC CLASS A COMMON STOCK SHOULD CONSULT ITS TAX ADVISOR WITH RESPECT TO THE PARTICULAR TAX CONSEQUENCES OF THE MERGER TO SUCH HOLDER.

For U.S. federal income tax purposes, the merger has been structured to qualify as a reorganization under the provisions of Section 368(a) of the Internal Revenue Code. Because the exchange of ChipPAC Class A common stock for STATS ADSs will represent an exchange of stock of a U.S. corporation for the stock of a non-U.S. corporation, the additional requirements of Section 367 of the Internal Revenue Code and the Treasury regulations thereunder must be met in order for ChipPAC stockholders to avoid recognizing gain in the merger. STATS and ChipPAC have submitted a ruling request to the IRS for the private letter ruling to the effect that the exchange of ChipPAC Class A common stock for STATS ADSs in the merger will not result in the recognition of gain under Section 367 of the Internal Revenue Code.

Shearman & Sterling LLP and Kirkland & Ellis LLP are of the opinion that the merger will constitute a reorganization within the meaning of Section 368(a) of the Internal Revenue Code (determined without the application of Section 367 of the Internal Revenue Code) and that each of STATS, ChipPAC and Camelot Merger, Inc. will be a party to the reorganization within the meaning of Section 368(b) of the Internal Revenue Code. These opinions rely upon certain factual representations made by STATS, ChipPAC and Camelot Merger, Inc., as of the date of this registration statement. In addition, it is a condition to the closing of the merger that STATS and ChipPAC shall have each received opinions to such effect from Shearman & Sterling LLP and Kirkland & Ellis LLP, respectively, which opinions shall not have been withdrawn or modified in any material respect. The issuance of such opinions is conditioned upon the receipt by each of Shearman & Sterling LLP and Kirkland & Ellis LLP of certain additional factual representations to be made by STATS, ChipPAC and Camelot Merger, Inc., which representations shall be dated on or before the date of such opinions and shall not have been withdrawn or modified in any materials respects.

It is also a condition to the closing of the merger that either (a) the IRS has issued the private letter ruling described above or (b) STATS and ChipPAC have each received an opinion from a nationally recognized law firm to the effect that for U.S. federal income tax purposes the exchange of ChipPAC Class A common stock for STATS ADSs in the merger will not result in the recognition of gain under Section 367 of the Internal Revenue Code, which private letter ruling or opinion shall not have been withdrawn or modified in any material respect at the time of the merger. Under the currently applicable Treasury regulations, the tax opinion referred to in (b) above could not be issued because the exchange of ChipPAC Class A common stock for STATS ADSs in the merger would likely result in the recognition of gain under Section 367 of the Internal Revenue Code unless the IRS issues the requested private letter ruling. Such tax opinions will neither bind the IRS nor preclude the IRS from adopting a contrary position. In addition, the tax opinions and the private letter ruling are subject to certain assumptions and qualifications and will be based on the truth and accuracy of certain assumptions, representations and covenants made by STATS and ChipPAC in certificates delivered or to be delivered to the IRS and counsel by the respective managements of STATS and ChipPAC prior to the effective time of the merger.

Exchange of ChipPAC Class A Common Stock for STATS ADSs. Provided that the conditions set forth in the prior two paragraphs are satisfied so that the merger qualifies as a reorganization and the exchange of ChipPAC Class A common stock for STATS ADSs in the merger qualifies as not resulting in the recognition of gain under Section 367 of the Internal Revenue Code, a U.S. Holder will not recognize any gain or loss upon receipt of STATS ADSs in exchange for such holder’s ChipPAC Class A common stock, except in respect of cash received instead of a fractional STATS ADS. The aggregate adjusted tax basis of the STATS ADSs (including fractional STATS ADSs deemed received and redeemed as described below) received in the merger will be equal to the aggregate adjusted tax basis of the shares of ChipPAC Class A common stock surrendered for the STATS ADSs. The holding period of the STATS ADSs (including fractional STATS ADSs deemed received and redeemed as described below) will include the period during which the shares of ChipPAC Class A common stock were held. If the merger does not qualify as a reorganization, U.S. Holders of ChipPAC Class A common stock will recognize gain or loss on the exchange of ChipPAC Class A common stock for STATS ADSs. If the merger qualifies as a reorganization (determined without the application of Section 367 of the Internal Revenue Code) but the exchange does not qualify for nonrecognition of gain under Section 367 of the Internal Revenue Code,

U.S. Holders of ChipPAC Class A common stock will recognize gain (but not loss) on the exchange of ChipPAC Class A common stock for STATS ADSs. A U.S. Holder’s capital gain or loss will generally equal the difference between (i) the sum of the fair market value of the STATS ADSs received and any cash received instead of a fractional STATS ADS and (ii) such holder’s basis in the ChipPAC Class A common stock surrendered. Any recognized capital gain or loss will be long-term capital gain or loss if the U.S. Holder’s holding period for the ChipPAC Class A common stock is more than one year at the time of the exchange. Long-term capital gains recognized by certain non-corporate U.S. Holders, including individuals, generally will be subject to a maximum rate of U.S. federal income tax of 15%.

Fractional shares. A U.S. Holder who receives cash instead of a fractional STATS ADS generally will be treated as having received a fractional STATS ADS and then as having sold the fractional STATS ADS for cash in the market. Gain or loss generally will be recognized based on the difference between the amount of cash received instead of the fractional share and the portion of the holder’s aggregate adjusted tax basis of the shares of ChipPAC Class A common stock surrendered which is allocable to the fractional STATS ADS. Such gain or loss generally will be long-term capital gain or loss if the holding period for such shares of ChipPAC Class A common stock is more than one year at the effective time of the merger.

Reporting requirements and backup withholding. Each holder of ChipPAC Class A common stock that receives STATS ADSs in the merger will be required to file a statement with its U.S. federal income tax return providing its basis in the ChipPAC Class A common stock surrendered and the fair market value of the STATS ADSs and any cash received in the merger, and to retain permanent records of this information relating to the merger. Certain non-corporate holders of ChipPAC Class A common stock may be subject to backup withholding at a 28% rate on cash payments received instead of fractional STATS ADSs. Backup withholding generally will not apply, however, to a holder of ChipPAC Class A common stock that furnishes a correct taxpayer identification number and certifies that it is not subject to backup withholding.

The following, in its entirety, constitutes the opinion of Shearman & Sterling LLP regarding the material U.S. federal income tax consequences to U.S. Holders of the ownership and disposition of STATS ADSs.

Distributions on the ADSs. Subject to the passive foreign investment company (PFIC) rules discussed below, distributions, if any, made with respect to the STATS ADSs will be included in the gross income of a U.S. Holder as dividend income to the extent of STATS’ current and accumulated earnings and profits, calculated pursuant to U.S. federal income tax principles. U.S. Holders must include such distributions in income on the date that distributions with respect to the underlying STATS ordinary shares are actually or constructively received by the STATS depositary. Subject to certain limitations, dividends paid to noncorporate U.S. Holders, including individuals, may be eligible for a reduced rate of taxation if STATS is a “qualified foreign corporation” for U.S. federal income tax purposes. A qualified foreign corporation includes (i) a foreign corporation that is eligible for the benefits of a comprehensive income tax treaty with the United States that includes an exchange of information program, and (ii) a foreign corporation if both (a) its stock with respect to which a dividend is paid or its ADSs backed by such stock are readily tradable on an established securities market within the United States and (b) the otherwise qualified corporation is not a PFIC. STATS believes that the STATS ordinary shares or the STATS ADSs are considered to be readily tradable on an established securities market within the United States and it is not a PFIC. No assurances can be made that distributions made with respect to the STATS ADSs are or will continue to be eligible for a reduced rate of taxation.

A corporate U.S. Holder will not be entitled to a dividends received deduction generally available upon the receipt of dividends distributed by U.S. corporations. Distributions in excess of STATS’ current and accumulated earnings and profits will be treated as a return of capital to the extent of the U.S. Holder’s basis in the STATS ADSs and thereafter as capital gain. Such capital gain will be long-term capital gain if the U.S. Holder’s holding period for the STATS ADSs is more than one year at the time of the sale or exchange.

Dividends received with respect to the STATS ADSs will constitute “passive income”, or, in the case of certain U.S. Holders, “financial services income”, and generally will be treated as income from sources without the United States for U.S. foreign tax credit limitation purposes. Under Section 904(g) of the Internal Revenue Code, dividends paid by a foreign corporation 50% or more of which is owned by U.S. persons may be treated as income from sources within the United States to the extent that the foreign corporation has more than a small amount of income from sources within the United States. STATS does not expect that it will be more than 50% owned by U.S. persons following the merger. Singapore taxes are paid by STATS and deemed to have been distributed to and paid by its shareholders. A U.S. Holder will not be subject to U.S. federal income tax on such amounts, and the U.S. Holder will not be eligible for foreign tax credits for such amounts against their U.S. federal income tax.

If a taxable dividend is paid in a currency other than the U.S. dollar, the amount includible in gross income will be the U.S. dollar value of such dividend, calculated by reference to the exchange rate in effect on the date of actual or constructive receipt of the dividend on the underlying ordinary shares by the STATS depositary, regardless of whether the payment is actually converted into U.S. dollars. Gain or loss, if any, realized as a result of the currency exchange fluctuations during the period from the date of distribution of the dividend to the date of conversion of the payment into U.S. dollars will be treated as ordinary income or loss. This gain or loss generally will be from sources within the United States for U.S. foreign tax credit limitation purposes. U.S. Holders should consult their own tax advisors concerning the possibility of foreign currency gain or loss if any such currency is not converted into U.S. dollars on the date of receipt.

Sale or exchange of the ADSs. Subject to the PFIC rules discussed below, upon the sale or exchange of STATS ADSs, a U.S. Holder generally will recognize capital gain or loss equal to the difference between (i) the amount of cash proceeds and the fair market value of any property received on the sale or exchange and (ii) such holder’s adjusted tax basis in the STATS ADSs sold or exchanged. Such capital gain or loss will be long-term capital gain or loss if the U.S. Holder’s holding period for the STATS ADSs is more than one year at the time of sale or exchange. Long-term capital gains recognized by certain non-corporate U.S. Holders, including individuals, generally will be subject to a maximum rate of tax of 15%. The deductibility of capital losses is subject to limitations. Such gain or loss generally will be treated as income or loss from sources within the United States for U.S. foreign tax credit limitation purposes.

PFIC. Special U.S. federal income tax rules apply to U.S. persons owning shares of a PFIC. A non-U.S. corporation generally will be classified as a PFIC for U.S. federal income tax purposes in any taxable year in which, after applying relevant look-through rules with respect to the income and assets of subsidiaries, either at least 75% of its gross income is “passive income”, or on average at least 50% of the gross value of its assets is attributable to assets that produce passive income or are held for the production of passive income. For this purpose, passive income generally includes dividends, interest, royalties, rents (other than rents and royalties derived in the active conduct of a trade or business and not derived from a related person), annuities and gains from assets that produce passive income.

The following discussion, insofar as it relates to matters of Singapore tax law, constitutes the opinion of Allen & Gledhill regarding the material Singapore tax, stamp duty and estate duty consequences of the purchase, ownership and disposal of STATS ordinary shares or STATS ADSs (collectively, the STATS shares), to a holder of the STATS shares who is not tax resident and who does not carry on business or otherwise have a presence in Singapore or, in the case of estate duty, is not domiciled in Singapore. The opinion of Allen & Gledhill will be filed as an exhibit to the registration statement, of which this document forms a part, filed with the SEC on Form F-4 prior to the time the registration statement is declared effective by the SEC. The statements made herein regarding taxation are general in nature and based on certain aspects of the tax laws of Singapore and administrative guidelines issued by the relevant authorities in force as of the date hereof and are subject to any changes in such laws or administrative guidelines, or in the interpretation of these laws or guidelines, occurring

after such date, which changes could be made on a retroactive basis. The statements made herein do not purport to be a comprehensive description of all of the tax considerations that may be relevant to all ChipPAC stockholders, some of which (such as dealers in securities) may be subject to special rules. ChipPAC stockholders are advised to consult their own tax advisors as to the Singapore or other tax consequences of the ownership of or disposition of the STATS shares, including, in particular, the effect of any foreign, state or local tax laws to which they are subject.

General. Nonresident corporate taxpayers are subject to income tax on income that is accruing in or derived from Singapore, and on foreign income received or deemed received in Singapore, subject to certain exceptions. A nonresident individual is subject to income tax on the income accruing in or derived from Singapore.

Subject to the provisions of any applicable double taxation treaty, nonresident taxpayers who derive certain types of income from Singapore are subject to a withholding tax on that income at a rate of 22% for the year of assessment 2004 or 20% for the year of assessment 2005 (assuming that the 2004 budget proposals announced by the Singapore Minister for Finance on February 27, 2004 are duly enacted), or 15% in the case of interest, royalty and rental of moveable equipment, subject to certain exceptions.

A corporation will be regarded as being tax resident in Singapore if the control and management of its business is exercised in Singapore (for example, if the corporation’s board of directors meets and conducts the business of the corporation in Singapore). An individual is tax resident in Singapore in a year of assessment if, in the preceding year, he or she was physically present in Singapore or exercised an employment in Singapore (other than as a director of a company) for 183 days or more, or if he or she resides in Singapore.

No comprehensive tax treaty currently exists between Singapore and the United States.

Dividend distributions. Dividends received in respect of STATS shares by either a resident or nonresident of Singapore are not subject to Singapore withholding tax.

Dividends paid out of tax-exempt income or income subject to concessionary tax rate. If STATS pays dividends on STATS shares out of income received that is exempt from tax because of STATS’ pioneer status or out of STATS’ income received that is subject to tax at a concessionary rate, if any, such dividends will be free from Singapore tax in the hands of the holders of STATS shares.

The above is not a comprehensive statement of all circumstances under which STATS may be able to pay tax exempt dividends.

Dividends paid out of income subject to normal corporate taxation—Impution system. Prior to January 1, 2003, Singapore was on the imputation system of corporate taxation. Under this system, the tax STATS paid on income subject to normal corporate income tax would be imputed to, and deemed to be paid on behalf of, STATS shareholders upon distribution of such income. Upon distribution of such income as dividends, STATS shareholders would have received dividends (franked dividends) net of such tax. The gross amount of dividends (that is, on the amount of net dividends plus an amount equal to the amount of gross dividends multiplied by the prevailing corporate tax rate applicable at the time of distribution) (which was 22% for the year of assessment 2003 and 2004 and (assuming that the 2004 budget proposals announced by the Singapore Minister of Finance on February 27, 2004 are duly enacted) 20% for the year of assessment 2005) would be subject to Singapore tax. In this way, the tax STATS paid would be available to STATS shareholders as a tax credit to offset their tax liability on their overall income subject to Singapore income tax (including the gross amount of dividends).

A nonresident shareholder is effectively taxed on Franked Dividends at the corporate income tax rate. Thus, because tax deducted from the dividend and paid by STATS at the corporate income tax rate is in effect imputed

to, and deemed paid on behalf of, STATS shareholders (as discussed in the preceding paragraph), no further Singapore income tax will be imposed on net dividends received by a nonresident holder of STATS ordinary shares or STATS ADSs. Further, the nonresident shareholder who does not have a permanent establishment in Singapore and deductible expenses attributed to such dividend income would normally not receive any tax refund from the Inland Revenue Authority of Singapore.

Dividends paid out of income subject to normal corporate taxation—New one-tier corporate tax system. A new one-tier corporate tax system became effective from January 1, 2003 (subject to certain transitional rules). Under this new system, the tax on corporate profits is final and dividends paid by a Singapore resident company will be tax exempt in the hands of the shareholder, regardless of whether the shareholder is a company or an individual and whether or not the shareholder is a Singapore tax resident. Accordingly, under the one-tier corporate tax system, no further Singapore income tax will be imposed on the net dividends received by a nonresident holder of STATS shares.

However, to enable companies to make use of their unutilized dividend franking credits as at December 31, 2002, there will be a five-year transitional period from January 1, 2003 to December 31, 2007, during which a company may remain on the imputation system for the purposes of paying franked dividends out of its unutilized dividend franking credits as at December 31, 2002. Accordingly, as long as STATS remains on the imputation system, STATS shareholders may continue to receive dividends with credits attached as described above under “Imputation System.”

For the transitional period from January 1, 2003 up to December 31, 2007, when the imputation system will co-exist with the one-tier corporate tax system, if STATS has not moved to the one-tier system, tax vouchers issued by STATS will distinguish between franked dividends and normal tax exempt dividends not being exempt dividends under the one-tier system, such as dividends paid out of tax exempt income, or amounts not taxed because of approved deduction, further deduction of expenses or foreign tax credit allowed. If STATS has fully utilized its dividend franking credits (that is, STATS is required to move to the one-tier system) or if STATS elects to move to the one-tier system at an earlier date, tax vouchers issued by STATS will distinguish between normal tax exempt dividends and exempt dividends under the one-tier system.

Capital gains on disposal of STATS shares. Singapore does not impose tax on capital gains. However, there are currently no specific laws or regulations which address the characterization of capital gains; hence gains or profits may be construed to be of an income nature and subject to tax, especially if they arise from activities which the Inland Revenue Authority of Singapore regards as the carrying on of a trade or business in Singapore.

There is no stamp duty payable in respect of the issuance and holding of STATS shares. Where securities evidenced in certificated form are acquired in Singapore, stamp duty is payable on the instrument of transfer of STATS shares at the rate of S$0.20 for every S$100 or part thereof of the consideration for, or market value of, STATS shares, whichever is higher. The stamp duty is borne by the purchaser unless there is an agreement to the contrary. Where an instrument of transfer is executed outside Singapore or no instrument of transfer is executed, no stamp duty is payable on the acquisition of STATS ordinary shares or STATS ADSs. However, stamp duty may be payable if the instrument of transfer is executed outside Singapore and received in Singapore.

In the case of an individual who is not domiciled in Singapore, Singapore estate duty is imposed on the value of immovable properties situated in Singapore passing on the death of the individual. Estate duty is not imposed on the movable properties in Singapore owned by a non-domiciled person. Thus, an individual holder of STATS securities who is not domiciled in Singapore at the time of his or her death will generally not be subject to Singapore estate duty on the value of STATS securities held by the individual upon the individual’s death.

Prospective purchasers of STATS securities who are individuals, whether or not domiciled in Singapore, should consult their own tax advisers regarding the Singapore estate duty consequences of their investment and ownership of STATS securities.

In accordance with United States generally accepted accounting principles, STATS will account for the merger using the purchase method of accounting. Under the purchase method of accounting, STATS will record the market value of the STATS ADSs issued in connection with the merger, the fair value of the options to purchase shares of ChipPAC Class A common stock that are substituted with STATS substitute options to purchase STATS ordinary shares and the amount of direct transaction costs as the cost of acquiring the business of ChipPAC. STATS will allocate that cost to the individual assets acquired and liabilities assumed, including various identifiable intangible assets (such as acquired technology and acquired trade names) based on their respective fair values at the date of the completion of the merger. Any excess of the purchase price over those fair values will be accounted for as goodwill.

Intangible assets with finite useful lives will generally be amortized over a specified period, resulting in an estimated accounting charge attributable to these items. In accordance with the Statement of Financial Accounting Standards No. 142, “Goodwill and Other Intangible Assets”, intangible assets with indefinite useful lives, including goodwill resulting from a business combination completed subsequent to June 30, 2001, will not be amortized but instead will be tested for impairment at least annually. The results of operations and cash flows of ChipPAC will be included in STATS’ financial statements prospectively as of the completion of the merger.

Under the provisions of the Hart-Scott-Rodino Act, the merger may not be consummated until the specified waiting period requirements of the Hart-Scott-Rodino Act have been satisfied. STATS and ChipPAC filed notification reports with the Antitrust Division and the FTC under the Hart-Scott-Rodino Act on March 9, 2004 and received early termination of the Hart-Scott-Rodino waiting period effective March 19, 2004.

In addition, under the Korean Monopoly Regulation and Fair Trade Act, as amended, STATS is required to file a share acquisition notification with the Korean FTC within 30 days after the consummation of the merger.

At any time before or after the completion of the merger, the Antitrust Division or the FTC could take any action under the antitrust laws as it deems necessary or desirable in the public interest, including seeking to enjoin the completion of the merger or seeking the divestiture of substantial assets of STATS or ChipPAC. In addition, certain private parties, state attorneys general or other antitrust authorities may challenge the transactions under antitrust laws under certain circumstances.

STATS and ChipPAC believe that the completion of the merger will not violate any antitrust laws. There can be no assurance, however, that a challenge to the merger on antitrust grounds will not be made, or, if such a challenge is made, what the result will be.

In addition, the completion of this merger is subject to the effectiveness of the registration statement of which this document is a part and compliance with applicable corporate laws of the State of Delaware.

The issuance of the STATS ADSs to be issued in the merger and the STATS ordinary shares underlying such STATS ADSs will be registered under the Securities Act. These STATS ADSs will be freely transferable under the Securities Act, except for STATS ADSs issued to any person who is deemed to be an affiliate of ChipPAC. Persons who may be deemed to be affiliates include individuals or entities that control, are controlled by, or are under common control with ChipPAC and may include some of ChipPAC’s officers and directors, as well as its principal stockholders. ChipPAC’s affiliates may not sell their STATS ADSs acquired in the merger except pursuant to:

The merger agreement requires that ChipPAC use its reasonable best efforts to deliver or cause to be delivered to STATS, not later than the effective time of the merger, a written agreement to the effect that these affiliated persons will not sell, transfer or otherwise dispose of any of the STATS ADSs issued to them in the merger in violation of the Securities Act or the related rules.

Under Delaware law, ChipPAC stockholders are not entitled to appraisal or dissenters’ rights in connection with the merger because, on the ChipPAC record date, ChipPAC Class A common stock was designated and quoted for trading on the Nasdaq National Market and will be converted into STATS ADSs, which, at the effective time of the merger, will be listed on the Nasdaq National Market.

Under Singapore law, holders of STATS ADSs are not entitled to appraisal or dissenters’ rights in connection with the merger or the other matters to be considered at the STATS extraordinary general meeting.

Quotation of STATS ADSs to be issued in the merger and the listing of the STATS ordinary shares

STATS has agreed to cause the STATS ADSs to be issued and to be reserved for issuance in connection with the merger to be approved for quotation on the Nasdaq National Market, subject to official notice of issuance. STATS also has agreed to cause the STATS ordinary shares underlying such STATS ADSs to be approved for listing on the Singapore Exchange, subject to official notification of issuance.

Delisting and deregistration of the ChipPAC Class A common stock after the merger

If the merger is completed, the ChipPAC Class A common stock will be delisted from the Nasdaq National Market and will be deregistered under the Exchange Act.

This section of the document describes the merger agreement. While STATS and ChipPAC believe that the description covers the material terms of the merger agreement, this summary may not contain all of the information that is important to you. This summary is qualified in its entirety by reference to the merger agreement, a copy of which is attached as Annex A to this document and is incorporated into this document by reference. You should read the merger agreement in its entirety, as it is the legal document governing this merger.

Following the adoption and approval of the merger agreement and approval of the merger by ChipPAC stockholders and the approval of the issuance of STATS ordinary shares in the merger and the other matters related to the merger by STATS shareholders, and the satisfaction or waiver of the other conditions to the merger, Camelot Merger, Inc., a wholly owned subsidiary of STATS, will merge with and into ChipPAC. ChipPAC will survive the merger as a wholly owned subsidiary of STATS. If all conditions to the merger are satisfied or waived, the merger will become effective at the time of the filing of a certificate of merger with the Secretary of State of the State of Delaware.

At the effective time of the merger, each issued and outstanding share of ChipPAC Class A common stock will be converted into the right to receive 0.87 STATS ADSs. However, any shares of ChipPAC Class A common stock owned by ChipPAC, STATS, or any of their direct or indirect wholly owned subsidiaries will be cancelled without conversion. The exchange ratio will be adjusted appropriately to reflect any stock split, reverse stock split, stock dividend, extraordinary cash dividends, reorganization, recapitalization, reclassification, combination, exchange of shares or other similar change with respect to STATS ordinary shares, STATS ADSs or ChipPAC Class A common stock occurring prior to the effective time of the merger.

Based on the exchange ratio of 0.87 and based on the number of shares of ChipPAC Class A common stock and options to purchase ChipPAC Class A common stock outstanding as of June 16, 2004, a total of approximately 85,741,262 STATS ADSs and options to purchase 78,763,292 STATS ordinary shares will be issued or granted in the merger.

At the effective time of the merger, all options to purchase shares of ChipPAC Class A common stock, whether vested or unvested, granted under the ChipPAC 1999 plan and ChipPAC 2000 plan that are outstanding and unexercised immediately prior to the effective time of the merger will be substituted with STATS substitute options to purchase STATS ordinary shares, subject to substantially similar terms and conditions as were applicable prior to the effective time of the merger, including, without limitation, any antidilution provisions, except where such terms and conditions must be changed to comply with Singapore law. ChipPAC will use reasonable efforts to take all necessary action, including obtaining the consent of any holder of options to purchase shares of ChipPAC Class A common stock, to implement such substitution. The number of STATS ordinary shares issuable upon the exercise of these STATS substitute options will be equal to the number of shares of ChipPAC Class A common stock subject to the substituted ChipPAC option multiplied by 8.7 (ten times the exchange ratio). Any fractional STATS ordinary shares resulting from such adjustment will be rounded down to the nearest whole number. The STATS substitute options issuable in the merger will have an exercise price per STATS ordinary shares equal to the exercise price per share of the substituted ChipPAC option divided by 8.7 (ten times the exchange ratio), subject to certain limitations. The exercise price will be rounded up to the nearest whole cent. Upon exercise of a STATS substitute option, the holder of such STATS substitute option may elect to receive, in lieu of STATS ordinary shares, a number of STATS ADSs equal to the number of STATS ordinary

shares subject to the relevant STATS substitute option divided by ten and rounded down to the nearest whole STATS ADS.

STATS is required to reserve for issuance a sufficient number of STATS ordinary shares for delivery upon the exercise of the STATS substitute options. STATS is required to file a registration statement covering the STATS ordinary shares issuable with respect to the STATS substitute options and is required to use its reasonable efforts to maintain the effectiveness of such registration statements for so long as the STATS substitute options remain outstanding.

After the effective time of the merger, STATS’ exchange agent will mail to each record holder of ChipPAC Class A common stock a letter of transmittal and instructions for surrendering their certificates. Only those holders who properly surrender their certificates representing ChipPAC Class A common stock in accordance with the instructions will receive the STATS ADSs to which the record holder is entitled, any cash (without interest) which may be payable in lieu of a fractional interest in a STATS ADS and any dividends or other distributions with respect to STATS ADSs declared or made after the effective time. The surrendered certificates representing shares of ChipPAC Class A common stock will be cancelled.

After the effective time of the merger, each certificate representing shares of ChipPAC Class A common stock that have not been surrendered will only represent (i) the number of STATS ADSs which the record holder is entitled to receive in the merger, (ii) the right to receive cash (without interest) in lieu of any fractional interest in a STATS ADS and (iii) any dividends or distributions that may be applicable. Following the effective time of the merger, ChipPAC will not register any transfers of ChipPAC Class A common stock on its stock transfer books.

STATS will not issue any fractional interests in STATS ADSs in the merger. Instead, each holder of shares of ChipPAC Class A common stock exchanged in the merger who would otherwise have received a fraction of a STATS ADS will receive cash, without interest, in an amount equal to the holder’s proportionate interest in the gross proceeds of the sale on the Nasdaq National Market by the exchange agent of the aggregated fractional STATS ADSs that otherwise would be issued in the merger. STATS will pay all commissions, transfer taxes and out-of-pocket costs, including the expenses and compensation of the exchange agent, incurred in connection with the sale by the exchange agent of the STATS ADSs.

After the effective date of the merger, no dividends or other distributions declared or made after the closing of the merger with respect to STATS ordinary shares will be paid to the holder of any unsurrendered ChipPAC certificate until the holder surrenders its ChipPAC certificate in accordance with the letter of transmittal.

If any ChipPAC Class A common stock certificate is lost, stolen or destroyed, a ChipPAC stockholder must provide an appropriate affidavit certifying that fact. STATS may require a ChipPAC stockholder to deliver a bond as indemnity against any claim that may be made against STATS with respect to any lost, stolen or destroyed certificate.

Holders of ChipPAC Class A common stock should not send in their certificates until they receive a letter of transmittal from the exchange agent.

STATS and ChipPAC each made a number of representations and warranties in the merger agreement regarding aspects of their respective businesses, financial condition, structure and other facts pertinent to the merger.

All representations and warranties of ChipPAC and STATS expire at the effective time of the merger.

The representations and warranties contained in the merger agreement are complicated and not easily summarized. You are urged to carefully read the articles of the merger agreement entitled “Representations and Warranties of the Company”, relating to ChipPAC and “Representations and Warranties of Parent”, relating to STATS.

The companies have agreed that unless the merger agreement states otherwise, until the earlier of the completion of the merger or unless the other company consents in writing, each company will use its reasonable best efforts:

The companies have also agreed that unless the merger agreement states otherwise, until the earlier of the completion of the merger or unless the other company consents in writing, each company will conduct its business in compliance with certain specific restrictions relating to the following:

The agreements related to the conduct of ChipPAC’s and STATS’ businesses in the merger agreement are complicated and not easily summarized. You are urged to carefully read the sections of the merger agreement entitled “Conduct of Business by the Company Pending the Merger” relating to ChipPAC and “Conduct of Business By Parent Pending the Merger” relating to STATS.

STATS and ChipPAC have further agreed to cease, as of the date of the merger agreement, any and all existing activities, discussions or negotiations with any parties conducted prior to that date with respect to any Competing Transactions, as defined in the merger agreement. The term “Competing Transaction” has a special meaning under the merger agreement, which is summarized after the next paragraph.

Until the merger is completed or the merger agreement is terminated, the companies and their subsidiaries have agreed not to, directly or indirectly, take any of the following actions:

A “Competing Transaction” is any transaction, other than the merger, involving any of the following:

STATS and ChipPAC have agreed to promptly inform each other if any proposal or offer regarding a Competing Transaction is made or, if any inquiry or contact with the party making the proposal regarding a Competing Transaction is made.

Either company’s board of directors may, without breaching the merger agreement, respond to an unsolicited, bona fide, written proposal or offer regarding a Competing Transaction by discussing the proposal with the party making the proposal, and furnishing information to the party making the proposal if all of the following conditions are met:

A “Superior Proposal” is an unsolicited, bona fide offer made by a third party to consummate any of the following transactions:

and where the transaction is on terms that such company’s board of directors determines in good faith, after having consulted with an internationally recognized financial advisor, is reasonably likely to be more favorable to such company’s shareholders from a financial point of view than the merger and reasonably capable of being completed on the proposed terms.

ChipPAC is obligated under the merger agreement to hold and convene the ChipPAC special meeting of stockholders for purposes of voting for the approval and adoption of the merger agreement. Unless the ChipPAC board of directors withdraws or modifies its recommendation to its stockholders in favor of the approval and adoption of the merger agreement, ChipPAC agrees to use its reasonable best efforts to solicit from its stockholders proxies in favor of the approval and adoption of the merger agreement. ChipPAC also agrees to take all other necessary or advisable action to secure the required vote or consent of its stockholders.

STATS is obligated under the merger agreement to hold and convene the STATS extraordinary general meeting of shareholders for purposes of voting on the issuance of STATS ordinary shares underlying the STATS ADSs that will be issued to holders of ChipPAC Class A common stock in the merger and the other matters related to the merger. Unless the STATS board of directors withdraws or modifies its recommendation to its shareholders in favor of the issuance of STATS ordinary shares in the merger or the other matters related to the merger, STATS agrees to use its reasonable best efforts to solicit from its shareholders proxies in favor of the STATS resolutions. STATS also agrees to take all other necessary or advisable action to secure the required vote or consent of its shareholders.

From the date of the merger agreement through the effective time of the merger, STATS has agreed, subject to the fiduciary duties of the STATS board of directors, not to increase the number of STATS directors who are nominees of STS and to maintain the size of the STATS board of directors at 11 members.

In addition, STATS has agreed to cause, subject to the fiduciary duties of the STATS board of directors, certain changes to the STATS board of directors at the effective time of the merger, including:

If any of Dr. Conn, Mr. McKenna, Mr. Norby or Dr. Park determine not to, or are unable to, serve on the STATS board of directors, ChipPAC may designate an alternate person to be nominated for election to the STATS board of directors who qualifies as an independent director under the rules of the Nasdaq National Market, subject to approval by STATS, which approval may not be unreasonably withheld.

For one year following the completion of the merger, STATS is required to, or required to cause the surviving corporation of the merger to, provide to ChipPAC employees compensation and employee benefit plans, programs and policies and fringe benefits (other than equity based compensation arrangements) that, in the aggregate, are substantially similar to those that were provided to the ChipPAC employees immediately prior to the execution of the merger agreement.

After the completion of the merger, STATS is required to, or required to cause the surviving corporation of the merger to, recognize the service of each ChipPAC employee determined as of the completion of the merger for purposes of eligibility and vesting under any employee benefit plans, programs or arrangements maintained by STATS, the surviving corporation, or any of their affiliates that employs any continuing ChipPAC employee, except that such crediting of service will not operate to duplicate any benefit or the funding of such benefit. Pre-existing condition limitations will be waived for continuing ChipPAC employees under each such employee benefit plan, program or arrangement that provides health benefits to these employees to the same extent waived under the applicable group health plan of STATS maintained prior to the completion of the merger, and each continuing ChipPAC employee will be given credit for amounts paid under the corresponding group health plan of STATS during the plan year in which the completion of the merger occurs for purposes of applying deductibles, co-payments and out-of-pocket maximums for such plan year.

STATS is required to cause the surviving corporation to honor for the one-year period following the consummation of the merger certain employment and severance agreements existing as of the date of the merger agreement between ChipPAC and any current or former director, officer or employee of ChipPAC. In addition, STATS is required to cause the surviving corporation of the merger to perform ChipPAC’s obligations under the ChipPAC employee retention plan, which provides for payments at specified times of severance and retention payments to selected employees of ChipPAC contingent upon the consummation of the merger in an aggregate cash amount of $5.0 million, and the individual award agreements to be entered into thereunder with participating employees of ChipPAC. For additional information regarding the ChipPAC employee retention plan, please see “The Merger — ChipPAC, Inc. Employee Retention and Severance Plan” beginning on page 91.

ChipPAC has agreed to provide to STATS, no later than 30 days after the signing of the merger agreement, a list of names and addresses of all persons who were, in the judgment of ChipPAC, affiliates of ChipPAC for purposes of Rule 145 under the Securities Act. ChipPAC has further agreed to use its reasonable best efforts to deliver to STATS, prior to the effective time, a letter from each such person agreeing, among other things, to abide by certain transfer restrictions pursuant to Rule 145.

STATS has agreed, at the effective time of the merger, to provide to each of the trustee under the ChipPAC 2.5% notes indenture and the trustee under the ChipPAC 8% notes indenture a supplemental indenture providing that the respective convertible subordinated notes are convertible into 0.87 STATS ADS for each share of ChipPAC Class A common stock into which the convertible subordinated notes were convertible immediately prior to the merger. In addition, prior to the effective time of the merger, ChipPAC will provide, and after the effective time of the merger the surviving corporation of the merger will provide, all notices to holders of ChipPAC convertible subordinated notes and ChipPAC senior subordinated notes and opinions and other documentation reasonably requested by the trustee under the indentures governing the ChipPAC convertible subordinated notes or the ChipPAC senior subordinated notes.

The obligations of STATS and ChipPAC to complete the merger and the other transactions contemplated by the merger agreement are subject to the satisfaction or waiver, to the extent legally permissible, of each of the following conditions before completion of the merger:

ChipPAC’s obligations to complete the merger and the other transactions contemplated by the merger agreement are subject to the satisfaction or waiver of each of the following additional conditions before completion of the merger:

STATS’ obligations to complete the merger and the other transactions contemplated by the merger agreement are subject to the satisfaction or waiver of each of the following additional conditions before completion of the merger:

Under the terms of the merger agreement, a Material Adverse Effect on either STATS or ChipPAC is defined to mean any change, event, violation, inaccuracy, circumstance or effect that, individually or when taken together with all other changes, events, violations, inaccuracies, circumstances and effects that have occurred prior to the date of determination of the occurrence of the Material Adverse Effect, is, or is reasonably likely to be, materially adverse to the business, financial condition or results of operations of such entity and its subsidiaries taken as a whole.

However, under the terms of the merger agreement, none of the following, alone or in combination, will be deemed to constitute, nor will any of the following be taken into account in determining whether there has been or will be a Material Adverse Effect on any entity:

Further, in the case of ChipPAC, any attrition of U.S.-based employees of ChipPAC or its subsidiaries will not be deemed to constitute, nor will it be taken into account in determining whether there has been or will be a Material Adverse Effect.

The merger agreement may be terminated by action taken or authorized by the terminating party’s board of directors, at any time prior to completion of the merger, whether before or after the approval and adoption of the merger agreement by ChipPAC stockholders as follows:

Either STATS or ChipPAC will pay the nonterminating party a termination fee of $40 million if any of the following conditions occur:

All fees and expenses incurred in connection with the merger and the merger agreement and any related transactions, including fees and expenses of advisors, will be paid by the party incurring such expenses whether or not the merger is consummated. STATS and ChipPAC will share equally in the payment of the filing fees under the Hart-Scott-Rodino Act and fees directly associated with the printing, filing and mailing of the registration statement on Form F-4, proxy statement and the STATS shareholder circular, but will not pay for the fees and expenses of advisors in relation to these actions.

Following the merger, it is expected that ChipPAC will continue its operations as a wholly owned subsidiary of STATS. The stockholders of ChipPAC will become holders of STATS ADSs, and their rights as holders of STATS ADSs will be governed by the STATS deposit agreement, the STATS memorandum of association and the STATS articles of association, each as currently in effect, and Singapore law. See “Comparison of Shareholder Rights” beginning on page 153, “Description of STATS Ordinary Shares” beginning on page 140 and “Description of STATS American Depositary Shares” beginning on page 144.

STATS and ChipPAC may amend the merger agreement before completion of the merger by mutual written consent approved by their respective boards of directors. However, after the approval and adoption of the merger

agreement by the stockholders of ChipPAC, the merger agreement cannot be amended to reduce or change the type of consideration into which each share of ChipPAC Class A common stock will be converted upon completion of the merger. In addition, either STATS or ChipPAC may extend the other’s time for the performance of any of the obligations or other acts under the merger agreement, waive any inaccuracies in the other’s representations and warranties and waive compliance by the other with any of the agreements or conditions contained in the merger agreement.

This section of this document describes agreements related to the merger agreement, including the STATS voting agreement, the ChipPAC voting agreement, the ChipPAC affiliate letter and the separation and employment arrangements with certain employees of ChipPAC. While STATS and ChipPAC believe that these descriptions cover the material terms of these agreements, these summaries may not contain all of the information that is important to you. Forms of these agreements are attached as annexes to this document, as exhibits to Annex A of this document or as exhibits to the registration statement, of which this document forms a part, filed with the SEC on Form F-4.

These STATS shareholders may vote their STATS ordinary shares and STATS ADSs on all other matters in a manner determined by the shareholder.

Within five business days after receipt of the STATS shareholders circular, each shareholder who entered into the voting agreement shall deliver to STATS, with a copy to the ChipPAC representative, a proxy in the form attached to the STATS shareholders circular, appointing the chief executive officer of ChipPAC or such other person designated in writing by ChipPAC, and failing the ChipPAC representative, a representative nominated by such shareholder, as its proxy to vote such shareholder’s shares in favor of the approval of the issuance of STATS ordinary shares in the merger and the other matters related to the merger.

Each STATS shareholder who is a party to the STATS voting agreement agreed, subject to limited exceptions, not to sell, otherwise transfer or create or permit to exist any liens of any nature with respect to the STATS ordinary shares and STATS ADSs owned, controlled or acquired, either directly or indirectly, by that person until the termination of the STATS voting agreement.

Except pursuant to existing financing agreements, each STATS shareholder who is party to the STATS voting agreement agreed not to sell or otherwise transfer the STATS ordinary shares and STATS ADSs owned, controlled or acquired, either directly or indirectly, by that person until 90 days after completion of the merger; provided, however, that each such STATS shareholder may transfer STATS ordinary shares or STATS ADSs

(i) to an affiliate of such shareholder or in a transaction consummated in accordance with any private placement exemption from the registration requirements of the Securities Act if each person to whom any of the STATS ordinary shares or STATS ADSs, or any interest in any of the STATS ordinary shares or STATS ADSs, is transferred agrees to be bound by the terms and provisions of the STATS voting agreement or (ii) if the number of STATS ordinary shares (whether in the form of STATS ordinary shares or STATS ADSs) sold during any three month period are equal to the maximum number of STATS ordinary shares that such shareholder would be permitted to sell during that three month period in accordance with Rule 144(e) under the Securities Act.

The STATS voting agreement will terminate upon the earlier to occur of the termination of the merger agreement or the completion of the merger or, in regard to any individual shareholder, the modification of the merger agreement in a manner materially adverse to such shareholder, unless such shareholder gives prior written consent to the modification, or by agreement between ChipPAC and the shareholder to terminate the STATS voting agreement. The STATS voting agreement is attached to this document as Annex B, and you are urged to read it in its entirety.

Each stockholder has also irrevocably appointed STATS as their lawful attorney and proxy to vote the shares of ChipPAC Class A common stock owned by such stockholder in favor of:

As of February 10, 2004, these ChipPAC stockholders entered into the ChipPAC voting agreement with respect to approximately 17,646,587 shares of ChipPAC Class A common stock beneficially owned by them which represented approximately 18.1% of the outstanding ChipPAC Class A common stock. As of the

None of the ChipPAC stockholders who are parties to the ChipPAC voting agreement were paid additional consideration in connection with entering into the ChipPAC voting agreement.

Each ChipPAC stockholder who is a party to the ChipPAC voting agreement agreed, subject to limited exceptions, not to sell, otherwise transfer or create or permit to exist any liens of any nature with respect to the ChipPAC securities owned, controlled or acquired, either directly or indirectly, by that person until the termination of the ChipPAC voting agreement; provided, however, that any stockholder or one or more of such stockholder’s affiliates shall be allowed to sell or otherwise transfer any of such stockholder’s ChipPAC securities to the extent such disposition or dispositions would prevent such stockholder from being a “five percent transferee shareholder” as defined in Section 1.367(a)-3(c)(5)(ii) of the U.S. Treasury Regulations as of the consummation of the merger, with the relevant U.S. income tax provisions to be applied by substituting “4.9 percent” for “five percent” for this purpose.

Each ChipPAC stockholder who is party to the ChipPAC voting agreement agreed not to sell or otherwise transfer the STATS ordinary shares or STATS ADSs owned, controlled or acquired, either directly or indirectly, by that person until 90 days after completion of the merger; provided, however, each ChipPAC stockholder may transfer STATS ordinary shares or STATS ADSs (i) to an affiliate of such stockholder or in a transaction consummated in accordance with any private placement exemption from the registration requirements of the Securities Act if each person to whom any of the STATS ordinary shares or STATS ADSs, or any interest in any of the STATS ordinary shares or STATS ADSs, is transferred agrees to be bound by the terms and provisions of the ChipPAC voting agreement or (ii) if the number of STATS ordinary shares (whether in the form of STATS ordinary shares or STATS ADSs) sold during any three month period are equal to the maximum number of STATS ordinary shares that such stockholder would be permitted to sell during that three month period in accordance with Rule 144(e) under the Securities Act. Certain stockholders who are party to the ChipPAC voting agreement may transfer STATS ordinary shares or STATS ADSs at any time to such stockholder’s limited partners, owners or equity holders provided that such transfer complies with the provisions of Rule 145 of the Securities Act.

The ChipPAC voting agreement will terminate upon the earlier to occur of the termination of the merger agreement and the completion of the merger or, with regard to any individual stockholder, the modification of the merger agreement in a manner materially adverse to such stockholder, unless such stockholder gives prior written consent to the modification, or by agreement between STATS and the stockholder to terminate the ChipPAC voting agreement. The ChipPAC voting agreement is attached to this document as Annex C, and you are urged to read it in its entirety.

No later than 30 days after the date of the merger agreement, ChipPAC shall deliver to STATS a list of names and addresses of those persons who were, in ChipPAC’s reasonable judgment, on such date, affiliates (within the meaning of Rule 145 of the rules and regulations promulgated under the Securities Act) of ChipPAC. ChipPAC shall use its reasonable best efforts to deliver or cause to be delivered to STATS, prior to the completion of the merger, an affiliate letter, executed by each of the persons identified as possible affiliates and any person who shall, to the knowledge of ChipPAC, become an affiliate of ChipPAC subsequent to the delivery of the initial list to STATS. Under the affiliate letters, such persons acknowledge the resale restrictions on the STATS ADSs to be received by them in the merger imposed by Rule 145 under the Securities Act. In accordance with the affiliate letters, STATS will be entitled to place appropriate legends on any American Depositary Receipts evidencing the STATS ADSs received by these ChipPAC stockholders in the merger. The form of affiliate letter is attached as Exhibit 6.08 to the merger agreement, which is attached to this document as Annex A, and you are urged to read it in its entirety.

STATS, ChipPAC and Mr. McKenna entered into a separation agreement pursuant to which Mr. McKenna has agreed to resign from his position as President and Chief Executive Officer of ChipPAC and to relinquish his position as a member of the ChipPAC board of directors, effective as of the consummation of the merger. STATS has agreed to nominate Mr. McKenna to serve, effective as of the consummation of the merger, as a member and Vice Chairman of the STATS board of directors for a term to continue until December 31, 2004.

Among other payments and benefits, Mr. McKenna will be eligible to receive from ChipPAC a lump sum payment in an amount equal to three times his annual salary and target bonus and full vesting and immediate exercisability of his outstanding options. For additional information regarding the terms of Mr. McKenna’s separation agreement, see “The Merger—Interests of certain persons in the merger and the related transactions” on page 87.

On February 26, 2004, after the signing of the merger agreement and announcement of the proposed merger, STATS, ChipPAC and Mr. Dennis Daniels entered into a five-year employment agreement, which will not become effective unless and until the merger is consummated.

Mr. Daniels will serve as the Vice President, Human Resources of the combined company for a term of five years.

Under his employment agreement, Mr. Daniels will receive annual base salary in the amount of $200,000. He will also be eligible to earn an annual cash bonus during each year of the five-year term and a retention bonus payable over the two-year period commencing on the day the merger is consummated. The amount of the annual bonus will be based on Mr. Daniels’ performance and will be determined at the end of the applicable incentive compensation plan year. The amount of the retention bonus is equal to $300,000. The retention bonus is payable at the rate of 25% of the bonus amount on the first payroll date following the consummation of the merger, 25% at the end of the first year following consummation of the merger, and 50% at the end of the second year following consummation of the merger. Subject to approval of the compensation committee of the STATS board of directors, Mr. Daniels will be granted under the STATS 1999 option plan an option to purchase a number of STATS ordinary shares as determined by the compensation committee on the date of grant having a per share exercise price equal to the fair market value of the STATS ordinary shares on the date of grant. Mr. Daniels will also be entitled to certain expatriate and repatriation benefits in connection with the relocation of Mr. Daniels and his immediate family to Singapore.

If (i) the combined company terminates the employment of Mr. Daniels without cause, (ii) he resigns for good reason during the two years following the consummation of the merger or (iii) he resigns for any reason during the three subsequent years, he will be entitled to payment of the unpaid portion of his retention bonus, his prorated annual incentive bonus, continuation of his salary for a maximum of six months following the date of termination, payment for the cost of maintaining COBRA coverage continuation during a maximum period of six months, automatic full vesting and immediate exercisability of his options outstanding on the date of the termination and, if Mr. Daniels’ place of employment is located outside the United States on the date of the termination, payment of the cost to repatriate Mr. Daniels and his immediate family to the United States.

If Mr. Daniels and the combined company mutually agree to terminate Mr. Daniels’ employment during the two-year period following the consummation of the merger, Mr. Daniels will be entitled to a prorated amount of the unpaid portion of his retention bonus, the prorated portion of his annual incentive bonus, continuation of his salary for a maximum of six months following the date of termination, payment for the cost of maintaining COBRA coverage continuation during a maximum period of six months and full vesting and immediate exercisability of options outstanding as of the date of termination and, if Mr. Daniels’ place of employment is located outside the United States on the date of termination, payment of the cost to repatriate Mr. Daniels and his immediately family to the United States.

In the event of Mr. Daniels’ death or in the case of termination of his employment due to his disability during the term of his agreement, Mr. Daniels or his estate, as applicable, will be entitled to payment of any unpaid prorated portion of the retention bonus, the prorated portion of his annual incentive bonus, full vesting and immediate exercisability of his options outstanding as of the date of the termination or death, as applicable, and, if Mr. Daniels’ place of employment is located outside the United States on the date of termination or death, as applicable, payment of the cost to repatriate Mr. Daniels and his immediate family to the United States.

Pursuant to his employment agreement, Mr. Daniels has agreed not to use or disclose any confidential information of STATS or its affiliates and to be bound during the 18 months following the consummation of the merger by a covenant not to compete with the combined company and during the 18 months following the termination of his employment by a covenant not to solicit the employees or business relations of the combined company.

On March 17, 2004, after the signing of the merger agreement and announcement of the proposed merger, STATS, ChipPAC and Mr. Potter, the Acting Chief Financial Officer of ChipPAC, entered into an employment agreement, which will not become effective unless and until the merger is consummated, pursuant to which Mr. Potter agreed to serve as Chief Financial Officer of the combined company.

For additional information regarding the terms and conditions of Mr. Potter’s employment agreement, see “The Merger—Interests of certain persons in the merger and related transactions” beginning on page 87.

STATS and ChipPAC have entered into employment agreements with each of Messrs. H.C. Han, Kenny Lee, Jin Aun Lew, B.K. Sohn and Chong Meng Ng in contemplation of the merger. None of these employment agreements will become effective until the consummation of the merger.

Mr. Ng will serve as the President and Managing Director, ChipPAC Shanghai, Mr. Lew will serve as the President and Managing Director, ChipPAC Malaysia and Mr. Sohn will serve as the President and Managing Director, ChipPAC Korea. The three foregoing managing directors will report directly to the Chief Executive Officer of the combined company. Mr. Han, who will serve as the Senior Vice President, Manufacturing Operations of the combined company, will report directly to the Managing Director, the Korea division of the combined company. Mr. Lee, who will serve as the Senior Vice President, Research and Development of the combined company, will report directly to the Chief Technology Officer of the combined company.

Their employment agreements, which were executed on or about the time that the merger agreement was executed, provide for Messrs. Ng, Lew, Sohn, Han and Lee to receive annual base salaries in the amounts of $170,000, MYR 575,000, KRW 156,060,000, KRW 81,606,586 and KRW 73,264,000, respectively. On June 9 and June 20, 2004, STATS and ChipPAC entered into an amended and restated employment agreement with each of Mr. Sohn and Mr. Ng, respectively, providing for an increased annual salary of KRW 171,615,000 and US$176,800, respectively, which increase is to be effective retroactively to April 1, 2004. Pursuant to their employment agreements, these individuals will also be eligible to earn an annual cash bonus and a retention bonus, which is payable over the two-year period commencing on the completion of the merger. The amount of the annual bonus will be based on the performance of the employee and will be determined at the end of the plan year. The amount of each retention bonus is equal to $170,000, MYR 575,000, KRW 312,120,000, KRW 81,606,586.50 and KRW 56,448,000 with respect to Messrs. Ng, Lew, Sohn, Han and Lee, respectively. The retention bonuses are payable at the rate of 25% of the bonus amounts on the first payroll date following the completion of the merger, 25% at the end of the first year following completion of the merger, and 50% at the end of the second year following completion of the merger. Pursuant to Mr. Ng’s employment agreement, he will also be entitled to additional benefits related to his status as an expatriate employee.

If the employee is involuntarily terminated (termination without cause or resignation for good reason), he will be entitled to payment of the unpaid portion of his retention bonus, his prorated annual incentive bonus, continuation of his salary for a maximum of six months following the date of termination, payment for the cost of maintaining COBRA coverage continuation during a maximum period of six months and automatic full vesting and immediate exercisability of his options outstanding on the date of the termination. In the case of an involuntary termination of Mr. Ng’s employment, STATS will continue to reimburse Mr. Ng for any continuing obligations he may have under his expatriate arrangements.

In the event of an employee’s death or in the case of an employment termination due to disability, the employee or his estate, as applicable, will be entitled to payment of any unpaid prorated portion of the retention bonus, the prorated portion of his annual incentive bonus and full vesting and immediate exercisability of options outstanding as of the date of the termination or an employee’s death, as applicable.

Pursuant to their employment agreements, the employees have each agreed not to use or disclose any confidential information of STATS or its affiliates and are bound during specified periods by covenants not to compete with the combined company (or its subsidiaries or affiliates) and a covenant not to solicit employees or business relations of the combined company.

At the STATS extraordinary general meeting, STATS will propose the following 12 STATS resolutions for approval of the STATS shareholders. STATS resolutions 1 through 11 will be proposed as ordinary resolutions and STATS resolution 12 will be proposed as a special resolution. STATS resolutions 1 through 11 require an affirmative vote of a simple majority of the votes cast at the extraordinary general meeting. STATS resolution 12 requires the affirmative vote of not less than three-fourths of the votes cast at the extraordinary general meeting. Each of the STATS resolutions will be voted on separately at the STATS extraordinary general meeting. If any of STATS resolutions 1 through 8 and 12 does not receive the requisite approval of the STATS shareholders, none of STATS resolutions 1 through 10 and 12 will be deemed approved by the STATS shareholders and the merger will not be consummated. STATS resolutions 9 and 10 are contingent upon the consummation of the merger and, even if such resolutions receive the requisite STATS shareholder approval, will be deemed approved by STATS shareholders only if the merger is consummated. STATS resolution 11 is not contingent upon the consummation of the merger and therefore will be approved if it receives the requisite STATS shareholder approval.

Resolution 1: Approve the issuance of STATS ordinary shares underlying the STATS ADSs that will be issued to ChipPAC stockholders on the terms and subject to the conditions set out in the merger agreement

In the merger, holders of ChipPAC Class A common stock will receive 0.87 STATS ADS for each share of ChipPAC Class A common stock they hold. Each STATS ADS represents the right to receive ten STATS ordinary shares. Such STATS ordinary shares shall be issued by STATS to the STATS depositary and, upon receipt, the STATS depositary shall issue to holders of ChipPAC Class A common stock 0.87 STATS ADS for each share of ChipPAC Class A common stock they hold.

As of June 16, 2004, there were approximately 98,553,175 shares of ChipPAC Class A common stock outstanding. Based on the exchange ratio of 0.87 and the number of shares of ChipPAC Class A common stock outstanding as of June 16, 2004, approximately 85,741,262 STATS ADSs would be issued to ChipPAC stockholders in connection with the merger, which would represent the right to receive approximately 857,412,623 STATS ordinary shares. In addition, assuming that all of the ChipPAC convertible subordinated notes outstanding as of March 31, 2004 were converted into ChipPAC Class A common stock prior to the consummation of the merger and that all of the ChipPAC stock options outstanding as of June 16, 2004 were exercised prior to the consummation of the merger, and based on the exchange ratio of 0.87 and the number of shares of ChipPAC Class A common stock outstanding as of June 16, 2004, approximately 114,172,111 STATS ADSs would be issued to ChipPAC stockholders in connection with the merger, which would represent the right to receive approximately 1,141,721,114 STATS ordinary shares.

At the STATS extraordinary general meeting, STATS will propose that its shareholders approve the issuance of the new STATS ordinary shares underlying the STATS ADSs that will be issued to ChipPAC stockholders on the terms and subject to the conditions set out in the merger agreement.

The affirmative vote of a majority of the votes cast at the STATS extraordinary general meeting is required to approve STATS resolution 1. STATS shareholders who collectively held approximately 59.2% of the outstanding STATS ordinary shares as of June 16, 2004 have entered into the STATS voting agreement requiring them to vote all of the STATS ordinary shares and STATS ADSs owned of record by such shareholders in favor of, among other things, STATS resolution 1. See “Agreements Related to the Merger—STATS voting agreement” beginning on page 116. As a result, approval of STATS resolution 1 is assured.

The STATS board of directors recommends that STATS shareholders vote FOR STATS resolution 1 to approve the issuance of the STATS ordinary shares underlying the STATS ADSs that will be issued to ChipPAC stockholders on the terms and subject to the conditions set out in the merger agreement.

Resolution 2: Approve and adopt the STATS ChipPAC substitute option plans under which the STATS substitute options will be granted in connection with the merger

When the merger is completed, stock options to acquire shares of ChipPAC Class A common stock granted to ChipPAC employees and directors under the ChipPAC 1999 plan and ChipPAC 2000 plan, in each case that are outstanding and not exercised as of immediately before the effective time of the merger, will be substituted with STATS substitute options. The STATS substitute options will be granted under the STATS ChipPAC substitute share option plan and the STATS ChipPAC substitute EIP, subject to approval by the STATS shareholders at the STATS extraordinary general meeting.

At the STATS extraordinary general meeting, STATS will propose that its shareholders approve and adopt the STATS ChipPAC substitute option plans under which the STATS substitute options will be granted in connection with the merger. The summaries of the STATS ChipPAC substitute share option plan and the STATS ChipPAC substitute EIP that follow are qualified in their entirety by reference to the respective plans, which are attached hereto as Annex F and Annex G, respectively.

Generally. In connection with the merger, STATS will adopt, subject to STATS shareholder approval, the STATS ChipPAC substitute share option plan. Adoption of the STATS ChipPAC substitute share option plan will permit STATS to grant STATS substitute options to holders of options granted under the ChipPAC 1999 Plan that are outstanding immediately prior to the effective time of the merger. STATS will grant STATS substitute options under the STATS ChipPAC substitute share option plan to employees, consultants and members of the board of directors of ChipPAC who hold ChipPAC options granted under the ChipPAC 1999 plan (the ChipPAC 1999 plan options). The number of STATS ordinary shares that may be issued upon the exercise of STATS substitute options granted under the STATS ChipPAC substitute share option plan may not exceed, in the aggregate, 7.2 million STATS ordinary shares, which is an aggregate number that is intended to approximate the maximum number of shares of ChipPAC Class A common stock that may be subject to outstanding ChipPAC 1999 plan options immediately prior to the effective time of the merger, multiplied by 8.7 (ten times the exchange ratio), subject to adjustment for certain changes in capitalization. The STATS ChipPAC substitute share option plan will be administered by a committee consisting of members of the STATS board of directors appointed by the STATS board of directors.

Terms and conditions of STATS substitute options. The STATS substitute options granted under the STATS ChipPAC substitute share option plan will be subject to terms and conditions that are substantially similar to the terms and conditions to which the ChipPAC 1999 plan options are subject. STATS substitute options granted in substitution for ChipPAC 1999 plan options that were intended to qualify as “incentive stock options” under the Internal Revenue Code will be granted in such a manner and will be subject to such terms and conditions in an effort to preserve their qualified status.

Shares issuable under substitute options. STATS substitute options are exercisable for STATS ordinary shares. The number of STATS ordinary shares issuable upon the exercise of a STATS substitute option will be equal to the number of shares of ChipPAC Class A common stock subject to the substituted ChipPAC 1999 plan option, multiplied by 8.7 (ten times the exchange ratio). Any fractional STATS ordinary shares resulting from adjustments resulting from the conversion will be rounded down to the nearest whole number. Upon exercise of a STATS substitute option, the holder of such STATS substitute option may elect to receive, in lieu of STATS ordinary shares, a number of STATS ADSs equal to the number of STATS ordinary shares subject to the relevant STATS substitute option, divided by ten and rounded down to the nearest whole STATS ADS. The number of shares of ChipPAC Class A common stock subject to substituted ChipPAC 1999 plan options was originally determined by the plan administrator of the ChipPAC 1999 plan.

Term. The term of each STATS substitute option granted under the STATS ChipPAC substitute share option plan will in no event exceed the term of the substituted ChipPAC 1999 plan option. The term of a substituted ChipPAC 1999 plan option was determined by the plan administrator of the ChipPAC 1999 plan, except that no incentive stock option was granted under the ChipPAC 1999 plan with a term that exceeded ten years from the date of grant, and no incentive stock option granted under the ChipPAC 1999 plan to an individual who owned stock representing more than 10% of the total combined voting power of all classes of capital stock of ChipPAC or its subsidiaries on the date of grant was granted with a term that exceeded five years from the date of grant. The substituted ChipPAC 1999 plan options generally have a term of ten years. Notwithstanding the foregoing, no STATS substitute option granted to a holder of substituted ChipPAC 1999 plan options who was not an employee of ChipPAC at the time of grant of the STATS substitute option may have a term that exceeds five years from the date of grant of the STATS substitute option.

Exercise Price. A STATS substitute option granted under the STATS ChipPAC substitute share option plan will have an exercise price per STATS ordinary share equal to the exercise price per share of the substituted ChipPAC 1999 plan option divided by 8.7 (ten times the exchange ratio), subject to certain limitations. The exercise price will be rounded up to the nearest whole cent. The exercise price of a substituted ChipPAC 1999 plan option was determined by the plan administrator of the ChipPAC 1999 plan, except that no incentive stock option was granted under the ChipPAC 1999 plan with an exercise price of less than 110% of the fair market value of the underlying shares to an individual who owned stock representing more than 10% of the total combined voting power of all classes of capital stock of ChipPAC or its subsidiaries on the date of grant, and no incentive stock option granted under the ChipPAC 1999 plan was granted to any other employee with an exercise price that was less than 100% of the fair market value of the underlying shares on the date of grant. In no event may the exercise price of a STATS substitute option granted under the STATS ChipPAC substitute share option plan be less than the par value of the underlying STATS ordinary shares.

Payment of exercise price. Holders of STATS substitute options granted under the STATS ChipPAC substitute share option plan may pay the exercise price using the same form of consideration permitted under the substituted ChipPAC 1999 plan options. The plan administrator of the ChipPAC 1999 plan determined the acceptable forms of consideration for paying the exercise price under the ChipPAC 1999 plan. The permissible forms of consideration include cash, check, or other ordinary shares of STATS.

Vesting. The STATS substitute options granted under the STATS ChipPAC substitute share option plan vest and become exercisable at the same rate and on the same basis that the substituted ChipPAC 1999 plan options vest and are exercisable. The vesting schedule applicable to the substituted ChipPAC 1999 plan options was fixed by the plan administrator of the ChipPAC 1999 plan on the date of grant.

Termination of employment (or consulting arrangement). The period during which a STATS substitute option granted under the STATS ChipPAC substitute share option plan is exercisable following termination of employment or cessation of consulting services with STATS by the option holder is the same period of time during which the substituted ChipPAC 1999 plan option is exercisable following a termination of employment or service. This post-termination exercisability period was fixed by the plan administrator of the ChipPAC 1999 plan and set forth in the agreement evidencing the option grant at the time of grant. Generally, in the absence of such a provision in the option agreement, vested STATS substitute options will remain exercisable for a period of 30 days following an employment termination of the option holder other than by reason of death or disability, and for a period of six months following a termination due to disability or death.

Non-transferability. The STATS substitute options granted under the STATS ChipPAC substitute share option plan are generally not transferable.

Amendment and termination. The STATS board of directors has the authority to amend or terminate the STATS ChipPAC substitute share option plan, except that a plan termination and no amendment may adversely

impact a holder of a STATS substitute option granted under the STATS ChipPAC substitute share option plan without the holder’s consent. Unless earlier terminated by the STATS board of directors, the STATS ChipPAC substitute share option plan is scheduled to terminate on the date that is the earlier of the 10th anniversary following the effective date of the plan and the date that each STATS substitute option granted under the STATS ChipPAC substitute share option plan has been exercised.

U.S. federal income tax consequences. The U.S. federal income tax consequences to the employee and to STATS differ depending on whether the STATS substitute option is a nonqualified stock option or an incentive stock option.

Nonqualified stock option. The grant of a nonqualified stock option has no immediate U.S. federal income tax effect: the option holder will not recognize taxable income and STATS will not receive a tax deduction.

When the option holder exercises a nonqualified stock option, the option holder will recognize ordinary income in an amount equal to the excess of the fair market value of the STATS ordinary shares on the date of exercise over the exercise price. STATS is required to withhold tax on the amount of income recognized. The tax basis of such STATS ordinary shares to the option holder will be equal to the exercise price paid, plus the amount includible in the option holder’s gross income, and the option holder’s holding period for such STATS ordinary shares will commence on the date on which the option holder recognized taxable income in respect of such STATS ordinary shares. Generally, STATS will receive a tax deduction equal to the amount of income recognized by the option holder.

When the option holder sells the STATS ordinary shares obtained from exercising a nonqualified stock option, any gain or loss will be taxed as a capital gain or loss (long-term or short-term, depending on how long the STATS ordinary shares have been held). Certain additional rules apply if the exercise price for an option is paid in STATS ordinary shares previously owned by the option holder.

Incentive stock option. When an eligible employee is granted an incentive stock option, or when the option holder exercises the option, the option holder will generally not recognize taxable income and STATS will not receive a tax deduction, except that upon the exercise of an incentive stock option, any excess of the fair market price of the STATS ordinary shares over the exercise price constitutes a tax preference item that may have alternative minimum tax consequences for the option holder. If the option holder sells the STATS ordinary shares received pursuant to the exercise of an incentive stock option more than one year after the date of transfer of such shares and more than two years after the date of grant of the incentive stock option, the option holder will normally recognize a long-term capital gain or loss equal to the difference, if any, between the sale price of any such shares and the exercise price. If the option holder does not hold the STATS ordinary shares for the required period, when the option holder sells the shares, the option holder will recognize ordinary compensation income and possibly capital gain or loss, and STATS will generally be entitled to a U.S. federal income tax deduction in the amount of such ordinary compensation income.

None of the executive officers of STATS or members of the STATS board of directors will be granted STATS substitute options under the STATS ChipPAC substitute share option plan. Executive officers of ChipPAC will be granted STATS substitute options to acquire an aggregate of approximately 3,082,576 STATS ordinary shares under the STATS ChipPAC substitute share option plan. No member of the ChipPAC board of directors who is not an employee of ChipPAC will be granted STATS substitute options under the STATS ChipPAC share option plan.

Generally. In connection with the merger, STATS will adopt, subject to STATS shareholder approval, the STATS ChipPAC substitute EIP. Adoption of the STATS ChipPAC substitute EIP will permit STATS to grant STATS substitute options to holders of options granted under the ChipPAC 2000 plan that are outstanding

immediately prior to the effective time of the merger. STATS will grant STATS substitute options under the STATS ChipPAC substitute EIP to employees and consultants of ChipPAC who hold ChipPAC options granted under the ChipPAC 2000 plan (the ChipPAC EIP options). The number of STATS ordinary shares that may be issued upon the exercise of STATS substitute options granted under the STATS ChipPAC substitute EIP may not exceed, in the aggregate, 73 million STATS ordinary shares, which is an aggregate number that is intended to approximate the maximum number of shares of ChipPAC Class A common stock that may be subject to outstanding ChipPAC EIP options immediately prior to the effective time of the merger, multiplied by 8.7 (ten times the exchange ratio), subject to adjustment for certain changes in capitalization. The STATS ChipPAC substitute EIP will be administered by a committee consisting of members of the STATS board of directors appointed by the STATS board of directors.

Terms and conditions of STATS substitute options. The STATS substitute options granted under the STATS ChipPAC substitute EIP will be subject to terms and conditions that are substantially similar to the terms and conditions to which the ChipPAC EIP options are subject. STATS substitute options granted in substitution for ChipPAC EIP options that were intended to qualify as “incentive stock options” under the Internal Revenue Code will be granted in such a manner and will be subject to such terms and conditions in an effort to preserve their qualified status.

Shares issuable under substitute options. STATS substitute options are exercisable for STATS ordinary shares. The number of STATS ordinary shares issuable upon the exercise of a STATS substitute option will be equal to the number of shares of ChipPAC Class A common stock subject to the substituted ChipPAC EIP option, multiplied by 8.7 (ten times the exchange ratio). Any fractional STATS ordinary shares resulting from adjustments resulting from the conversion will be rounded down to the nearest whole STATS ordinary share. Upon exercise of a STATS substitute option, the holder of the STATS substitute option may elect to receive, in lieu of STATS ordinary shares, a number of STATS ADSs equal to the number of STATS ordinary shares subject to the relevant STATS substitute option, divided by ten and rounded down to the nearest whole STATS ADS. The number of shares of ChipPAC Class A common stock subject to substituted ChipPAC EIP options was originally determined by the plan administrator of the ChipPAC 2000 plan.

Term. The term of the STATS substitute options granted under the STATS ChipPAC substitute EIP will in no event exceed the term of the substituted ChipPAC EIP option. The term of a substituted ChipPAC EIP option was determined by the plan administrator of the ChipPAC 2000 plan, except that no incentive stock option was granted under the ChipPAC 2000 plan with a term that exceeded ten years from the date of grant, and no incentive stock option granted under the ChipPAC 2000 plan to an employee who owned stock representing more than 10% of the total combined voting power of all classes of capital stock of ChipPAC or its subsidiaries on the date of grant with a term that exceeded five years from the date of grant. The substituted ChipPAC EIP options generally have a term of ten years. Notwithstanding the foregoing, no STATS substitute option granted to a holder of substituted ChipPAC EIP options who was not an employee of ChipPAC at the time of grant of the STATS substitute option may have a term that exceeds five years from the date of grant of the STATS substitute option.

Exercise price. The STATS substitute options will have an exercise price per STATS ordinary share equal to the exercise price per share of the substituted ChipPAC EIP option, divided by 8.7 (ten times the exchange ratio), subject to certain limitations. The exercise price will be rounded up to the nearest whole cent. The exercise price of a substituted ChipPAC EIP option was determined by the plan administrator of the ChipPAC 2000 plan at the time of grant, except that no incentive stock option was granted under the ChipPAC 2000 plan with an exercise price of less than 110% of the fair market value of the underlying shares to an employee who owned stock representing more than 10% of the total combined voting power of all classes of capital stock of ChipPAC or its subsidiaries on the date of grant, and no incentive stock option granted under the ChipPAC 2000 plan was granted to any other employee with an exercise price that was less than 100% of the fair market value of the underlying shares on the date of grant. In no event may the exercise price of a STATS substitute option granted under the STATS ChipPAC substitute share option plan be less than the par value of the underlying STATS ordinary shares.

Payment of exercise price. Holders of STATS substitute options granted under the STATS ChipPAC substitute EIP may pay the exercise price using the same form of consideration permitted under the substituted ChipPAC EIP options. The plan administrator of the ChipPAC 2000 plan determined the acceptable forms of consideration for paying the exercise price under the ChipPAC 2000 plan. The permissible forms of consideration include cash, check, or other ordinary shares of STATS.

Vesting. The STATS substitute options granted under the STATS ChipPAC substitute EIP vest and become exercisable at the same rate and on the same basis that the substituted ChipPAC EIP options vest and are exercisable. The vesting schedule applicable to the substituted ChipPAC EIP options was fixed by the plan administrator of the ChipPAC 2000 plan on the date of grant.

Termination of employment (or consulting arrangement). The period during which a STATS substitute option granted under the STATS ChipPAC substitute EIP is exercisable following termination of employment or cessation of consulting services with STATS by the option holder is the same period of time during which the substituted ChipPAC EIP option was exercisable following termination of service. This post-termination exercisability period was fixed by the plan administrator of the ChipPAC 2000 plan and set forth in the agreement evidencing the option grant at the time of grant. Generally, in the absence of such a provision in the option agreement, vested STATS substitute options will remain exercisable for a period of 30 days following an employment termination or other service termination of the option holder other than by reason of death, disability or retirement and for a period of six months following a termination due to disability or death and for a period of 30 days upon a qualifying retirement.

Change in control. The plan administrator is authorized to direct STATS to cash out all outstanding STATS substitute options granted under the STATS ChipPAC substitute EIP in connection with a change in control of STATS (as defined in the STATS ChipPAC substitute EIP).

Merger or sale of assets. In the event of a merger or sale of substantially all of the assets of STATS, each outstanding STATS substitute option granted under the STATS ChipPAC substitute EIP must be assumed by the successor corporation or substituted with an equivalent option or right to acquire shares of the successor corporation. If the successor refuses such assumption or substitution, all outstanding STATS substitute options granted under the STATS ChipPAC EIP will vest and become immediately exercisable for a specified period following the triggering corporate transaction.

Buyout. The plan administrator has the authority to at any time offer to buy out for a payment in cash or STATS ordinary shares any STATS substitute option granted under the STATS ChipPAC substitute EIP.

Non-transferability. The STATS substitute options granted under the STATS ChipPAC substitute EIP are generally not transferable.

Amendment and termination. The STATS board of directors has the authority to amend or terminate the STATS ChipPAC substitute EIP. Unless earlier terminated by the STATS board of directors, the STATS ChipPAC substitute EIP is scheduled to terminate on the earlier of the date that no STATS substitute option remains exercisable under the plan and the tenth anniversary of the date the STATS ChipPAC substitute EIP becomes effective.

When the option holder exercises a nonqualified stock option, the option holder will recognize ordinary income in an amount equal to the excess of the fair market value of the STATS ordinary shares on the date of exercise over the exercise price. STATS is required to withhold tax on the amount of income recognized. The tax basis of such shares to the option holder will be equal to the exercise price paid, plus the amount includible in the option holder’s gross income, and the option holder’s holding period for such shares will commence on the date on which the option holder recognized taxable income in respect of such shares. Generally, STATS will receive a tax deduction equal to the amount of income recognized by the option holder.

Incentive stock option. When an eligible employee is granted an incentive stock option, or when the option holder exercises the option, the option holder will generally not recognize taxable income and STATS will not receive a tax deduction, except that upon the exercise of an incentive stock option, any excess of the fair market price of the STATS ordinary shares over the exercise price constitutes a tax preference item that may have alternative minimum tax consequences for the option holder. If the option holder sells the STATS ordinary shares, shares received pursuant to the exercise of an incentive stock option more than one year after the date of transfer of such shares and more than two years after the date of grant of the incentive stock option, the option holder will normally recognize a long-term capital gain or loss equal to the difference, if any, between the sale price of any such shares and the exercise price. If the option holder does not hold the STATS ordinary shares for the required period, when the option holder sells the shares, the option holder will recognize ordinary compensation income and possibly capital gain or loss, and STATS will generally be entitled to a U.S. federal income tax deduction in the amount of such ordinary compensation income.

None of the existing executive officers of STATS or members of the STATS board of directors will be granted STATS substitute options under the STATS ChipPAC substitute EIP. Executive officers of ChipPAC will be granted STATS substitute options to acquire an aggregate of approximately 23,014,275 STATS ordinary shares under the STATS ChipPAC substitute EIP.

The affirmative vote of a majority of the votes cast at the STATS extraordinary general meeting is required to approve STATS resolution 2. STATS shareholders who collectively held approximately 59.2% of the outstanding STATS ordinary shares as of June 16, 2004 have entered into the STATS voting agreement requiring them to vote all of the STATS ordinary shares and STATS ADSs owned of record by such shareholders in favor of, among other things, STATS resolution 2. See “Agreements Related to the Merger—STATS voting agreement” beginning on page 116. As a result, approval of STATS resolution 2 is assured.

The STATS board of directors recommends that STATS shareholders vote FOR STATS resolution 2 to approve and adopt the STATS ChipPAC substitute option plans under which the STATS substitute options will be issued in connection with the merger.

Resolution 3: Approve the offer and grant of the STATS substitute options to replace the outstanding options to acquire ChipPAC Class A common stock and the issuance of new STATS ordinary shares as may be required to be issued pursuant to the exercise of such STATS substitute options

At the effective time of the merger, each outstanding ChipPAC stock option granted under the ChipPAC 1999 plan and ChipPAC 2000 plan, will be substituted with a STATS substitute option to purchase a number of STATS ordinary shares equal to the number of shares of ChipPAC Class A common stock subject to such ChipPAC option, multiplied by 8.7 (ten times the exchange ratio), at a per STATS ordinary share exercise price

equal to the exercise price per share of the substituted ChipPAC option divided by 8.7 (ten times the exchange ratio). Upon exercise of a STATS substitute option, the holder of such STATS substitute option may elect to receive, in lieu of STATS ordinary shares, a number of STATS ADSs equal to the number of STATS ordinary shares subject to the STATS substitute option divided by ten and rounded down to the nearest whole STATS ADS.

As of June 16, 2004, there were options to acquire approximately 9,053,252 shares of ChipPAC Class A common stock outstanding. Based on the number of shares of ChipPAC Class A common stock subject to outstanding options as of June 16, 2004, and 8.7 (ten times the exchange ratio), approximately 78,763,292 STATS ordinary shares (either directly or in the form of STATS ADSs) may be required to be issued pursuant to the exercise of STATS substitute options. The issuance of the STATS ordinary shares (directly or in the form of STATS ADSs) as may be required to be issued pursuant to the exercise of STATS substitute options is subject to approval by the STATS shareholders at the STATS extraordinary general meeting.

At the STATS extraordinary general meeting, STATS will propose that its shareholders approve the offer and grant of the STATS substitute options to substitute for the outstanding options to acquire ChipPAC Class A common stock and the issuance of new STATS ordinary shares as may be required to be issued pursuant to the exercise of such STATS substitute options.

The affirmative vote of a majority of the votes cast at the STATS extraordinary general meeting is required to approve STATS resolution 3. STATS shareholders who collectively held approximately 59.2% of the outstanding STATS ordinary shares as of June 16, 2004 have entered into the STATS voting agreement requiring them to vote all of the STATS ordinary shares and STATS ADSs owned of record by such shareholders in favor of STATS resolution 3. See “Agreements Related to the Merger—STATS voting agreement” beginning on page 116. As a result, approval of STATS resolution 3 is assured.

The STATS board of directors recommends that STATS shareholders vote FOR STATS resolution 3 to approve the offer and grant of the STATS substitute options to replace the outstanding options to acquire ChipPAC Class A common stock and the issuance of new STATS ordinary shares as may be required to be issued pursuant to the exercise of such STATS substitute options.

Resolution 4: Approve the entry into any supplemental indenture or other agreement in connection with the assumption by STATS of certain obligations under the ChipPAC convertible subordinated notes and the issuance of new STATS ordinary shares underlying the STATS ADSs as may be required to be issued pursuant to the conversion of the ChipPAC convertible subordinated notes into STATS ADSs after the merger

As of March 31, 2004, ChipPAC had outstanding $150 million aggregate principal amount of ChipPAC 2.5% convertible subordinated notes and $50 million aggregate principal amount of ChipPAC 8% convertible subordinated notes. The ChipPAC 2.5% notes indenture provides that after the consummation of the merger, the holders of the ChipPAC 2.5% convertible subordinated notes will be entitled to convert such notes into the number of STATS ADSs that they would have received in the merger if they had converted such notes into ChipPAC Class A common stock immediately prior to the merger. If the ChipPAC 2.5% convertible subordinated notes are outstanding at the time the merger is consummated, as a condition precedent to the merger, STATS and the trustee must enter into a supplemental indenture to implement this modification in the conversion rights of the ChipPAC 2.5% convertible subordinated notes. In addition, the ChipPAC 8% notes indenture provides that after the consummation of the merger, the holder of the ChipPAC 8% convertible subordinated notes will be entitled to convert such notes into the number of STATS ADSs that it would have received in the merger if it had converted such notes into ChipPAC Class A common stock immediately prior to the merger. If the ChipPAC 8% convertible subordinated notes are outstanding at the time the merger is consummated, as a condition precedent to the merger, STATS and the trustee must enter into a supplemental indenture to implement this modification in the conversion rights of the ChipPAC 8% convertible subordinated notes.

Based on the exchange ratio of 0.87 and the conversion price of the ChipPAC convertible subordinated notes on June 16, 2004, if all of the holders of the ChipPAC convertible subordinated notes exercised their conversion right, approximately 20,554,520 STATS ADSs would be issued in connection with the merger to the holders of the ChipPAC convertible subordinated notes, which would represent the right to receive approximately 205,545,200 STATS ordinary shares.

At the STATS extraordinary general meeting, STATS will propose that its shareholders approve the entry into any supplemental indenture or other agreement in connection with the assumption by STATS of certain obligations under the ChipPAC convertible subordinated notes and the issuance of new STATS ordinary shares underlying the STATS ADSs as may be required to be issued pursuant to the conversion of the ChipPAC convertible subordinated notes into STATS ADSs after the merger.

The affirmative vote of a majority of the votes cast at the STATS extraordinary general meeting is required to approve STATS resolution 4. STATS shareholders who collectively held approximately 59.2% of the outstanding STATS ordinary shares as of June 16, 2004 have entered into the STATS voting agreement requiring them to vote all of the STATS ordinary shares and STATS ADSs owned of record by such shareholders in favor of STATS resolution 4. See “Agreements Related to the Merger—STATS voting agreement” beginning on page 116. As a result, approval of STATS resolution 4 is assured.

The STATS board of directors recommends that STATS shareholders vote FOR STATS resolution 4 to approve the entry into any supplemental indenture or other agreement in connection with the assumption by STATS of certain obligations under the ChipPAC convertible subordinated notes and the issuance of new STATS ordinary shares underlying the STATs ADSs as may be required to be issued pursuant to the conversion of the ChipPAC convertible subordinated notes into STATS ADSs after the merger.

Resolutions 5 through 8: Elect as directors of STATS, with effect from the effective date of the merger, the following persons: Dr. Conn, Mr. McKenna, Mr. Norby and Dr. Park

At the STATS extraordinary general meeting, STATS will propose that its shareholders approve the resolutions to elect each of Dr. Conn, Mr. McKenna, Mr. Norby and Dr. Park to the STATS board of directors. If Mr. McKenna is elected to the STATS board of directors, he will be appointed as Vice Chairman of the STATS board of directors and will serve in that capacity and as a director until December 31, 2004. For additional information regarding these nominees to the STATS board of directors, see “Directors and Executive Officers of STATS” beginning on page 138.

The affirmative vote of a majority of the votes cast at the STATS extraordinary general meeting is required to approve each of STATS resolutions 5 through and including STATS resolution 8. STATS shareholders who collectively held approximately 59.2% of the outstanding STATS ordinary shares as of June 16, 2004 have entered into the STATS voting agreement requiring them to vote all of the STATS ordinary shares and STATS ADSs owned of record by such shareholders in favor of, among other things, STATS resolutions 5 through and including STATS resolution 8. As a result, approval of each of STATS resolutions 5 through and including STATS resolution 8 is assured.

The STATS board of directors recommends that STATS shareholders vote FOR STATS resolutions 5 through 8 to elect each of Dr. Conn, Mr. McKenna, Mr. Norby and Dr. Park to the STATS board of directors.

Resolution 9: Approve an amendment of the STATS 1999 option plan to increase the maximum number of STATS ordinary shares issuable under the STATS 1999 option plan to 245 million STATS ordinary shares and the issuance of new STATS ordinary shares upon the exercise of options granted under the STATS 1999 option plan

The STATS 1999 option plan was adopted by the STATS board of directors on May 28, 1999 and approved by the STATS shareholders at the 1999 annual general meeting held on May 28, 1999. The STATS executive resource and compensation committee, which administers the STATS 1999 option plan, has amended the STATS

1999 option plan from time to time to accomplish varying objectives, including, among other purposes, to comply with changes in applicable laws and to bring the plan in line with current market practices. Currently, a maximum of 190 million STATS ordinary shares may be issued under the STATS 1999 option plan. As of June 16, 2004, a total of 76,679,475 STATS ordinary shares had been issued under the STATS 1999 option plan or were subject to options outstanding under the plan, leaving 113,320,525 STATS ordinary shares available for future option grants under the STATS 1999 option plan.

STATS’ performance depends on STATS’ ability to recruit and retain the best-qualified employees. STATS does this, in part, by offering compensation and benefit programs that provide value to its employees. The STATS board of directors believes that the use of equity compensation is critical to motivating its current employees, attract new talent and align employees’ interests with those of the STATS shareholders. The STATS board of directors has observed that if the proposed merger is consummated, the number of employees of STATS and its subsidiaries would increase from approximately 4,000 full-time employees to approximately 10,300 full-time employees. In light of the significant increase in the number of employees STATS would have if the merger is consummated, the STATS board of directors has adopted, subject to shareholders approval, an amendment to the STATS 1999 option plan increasing the number of STATS ordinary shares available for issuance under the STATS 1999 option plan from 190 million to 245 million.

At the STATS extraordinary general meeting, the STATS board of directors will seek shareholder approval of the proposed amendment of the STATS 1999 option plan described above and the issuance of new STATS ordinary shares upon the exercise of any options granted under the STATS 1999 option plan. The following summary of the principal provisions of the STATS 1999 option plan as amended is qualified in its entirety by the specific language of the STATS 1999 option plan, a copy of which is attached hereto as Annex H.

The purpose of the STATS 1999 option plan is to offer selected individuals an opportunity to acquire or increase an ownership interest in STATS through the grant of options to purchase STATS ordinary shares. Options granted under the STATS 1999 option plan may be either nonqualified options or incentive stock options intended to qualify under Section 422 of the Internal Revenue Code.

Currently, the aggregate number of STATS ordinary shares that may be issued under the STATS 1999 option plan may not exceed 190 million shares (subject to anti-dilution adjustment pursuant to the STATS 1999 option plan). The STATS board of directors has amended the STATS 1999 option plan, subject to shareholder approval, to increase by 95 million the aggregate maximum number of STATS ordinary shares that may be issued under the STATS 1999 option plan, resulting in a new aggregate maximum of 245 million STATS ordinary shares. If an outstanding option granted under the STATS 1999 option plan expires for any reason, is returned to the option pool in satisfaction of some or all of the exercise price of such an option or in satisfaction of any tax withholding requirement or is cancelled or otherwise terminated, the STATS ordinary shares allocable to the unexercised portion of the option will again become available for future grants of options under the STATS 1999 option plan. In addition, shares issuable under outstanding STATS substitute options granted under the STATS ChipPAC substitute option plans that expire for any reason, are returned to the option pool in satisfaction of some or all of the exercise price of an option or in satisfaction of any tax withholding, or is cancelled or otherwise terminated, will become available for future grants of options under the STATS 1999 option plan.

The STATS 1999 option plan is administered by the STATS executive resource and compensation committee. Employees, outside directors and consultants of STATS and any affiliate of STATS (including any parent or subsidiary) are eligible to be granted options under the STATS 1999 option plan except that: (i) an employee of an affiliate and any individual who is an outside director or consultant is not eligible to be granted incentive share options; and (ii) an employee, outside director or consultant of an affiliate of STATS, other than a parent of STATS or any subsidiary of STATS, who is a resident of the United States is not eligible to participate in the STATS 1999 option plan.

An individual who owns more than 10% of the total combined voting power of all classes of STATS outstanding shares or of the shares of a STATS parent or subsidiary is not eligible to be granted incentive stock options unless the exercise price of the option is at least 110% of the fair market value of the underlying shares on the date of grant and the option by its terms is not exercisable after five years from the date of grant.

The exercise price of an incentive stock option may not be less than 100% of the fair market value of the underlying shares on the date of grant. In no event may the exercise price of an option be less than the par value of the underlying shares.

The exercisability of options outstanding under the STATS 1999 option plan may be fully or partially accelerated under certain circumstances such as a change in control of STATS, as defined in the STATS 1999 option plan.

Each option granted under the STATS 1999 option plan is evidenced by a share option agreement outlining the terms and conditions of the options, subject to the following: (i) the term of an option may not exceed ten years from the date of grant for an option holder who is an employee of STATS or any of its subsidiaries, and may not exceed five years from the date of grant for an option holder who is not an employee of STATS or any of its subsidiaries; (ii) if the option holder’s employment or service is terminated, the option holder may exercise all or part of the option holder’s options at any time before expiration of the options to the extent that the options had become exercisable before the termination of employment or service (or became exercisable as a result of termination), unless otherwise determined by the STATS board of directors in its sole discretion and (iii) the balance of the options will lapse when the option holder’s employment or service terminates.

Each option holder under the STATS 1999 option plan agrees to be bound by the applicable terms of any lock-up agreement between STATS and any underwriter that restricts or prohibits transactions in STATS ordinary shares for any period of time.

The STATS executive resource and compensation committee may modify, extend or assume outstanding options or may accept the cancellation of outstanding options in return for the grant of new options for the same or a different number of STATS ordinary shares and at the same or a different exercise price. No modification of an outstanding option may, without the consent of the option holder, impair the option holder’s rights or increase the option holder’s obligations under the option holder’s outstanding option. Options granted under the STATS 1999 option plan are generally not transferable.

In the event of certain changes in the capitalization of STATS, the STATS executive resource and compensation committee is required to make appropriate adjustments in one or more of the number of the following: (i) STATS ordinary shares available for future options granted under the STATS 1999 option plan; (ii) the number of STATS ordinary shares covered by each outstanding option and (iii) the exercise price of each outstanding option. If STATS is a party to a merger or consolidation, options outstanding under the STATS 1999 option plan will be subject to the agreement of merger or consolidation.

Unless terminated earlier by the STATS executive resource and compensation committee, the STATS 1999 option plan will terminate automatically on May 28, 2009. The STATS executive resource & compensation committee may amend, suspend or terminate the STATS 1999 option plan at any time and for any reason, provided that any amendment that increases the number of STATS ordinary shares available for issuance under the STATS 1999 option plan, or that materially changes the class of persons who are eligible for the grant of incentive share options, will be subject to the approval of STATS shareholders.

As of June 16, 2004, options to purchase an aggregate of 64,155,285 STATS ordinary shares were outstanding, out of which 15,137,000 were held by all STATS directors and executive officers as a group. The exercise prices of these options range from S$0.25 to S$6.93. The expiration dates of these options range from June 2004 to February 2014.

The U.S. federal income tax consequences to the employee and to STATS differ depending on whether the stock option is a nonqualified stock option or an incentive stock option.

Nonqualified stock option. The grant of a nonqualified stock option has no immediate U.S. federal income tax effect: the option holder will not recognize taxable income and STATS will not receive a tax deduction.

When the option holder exercises a nonqualified stock option, the option holder will recognize ordinary income in an amount equal to the excess of the fair market value of the STATS ordinary shares on the date of exercise over the exercise price. STATS is required to withhold tax on the amount of income recognized. The tax basis of such shares to the option holder will be equal to the exercise price paid, plus the amount includible in the option holder’s gross income, and the option holder’s holding period for such shares will commence on the date on which the option holder recognized taxable income in respect of such shares. Generally, STATS will receive a tax deduction equal to the amount of income recognized by the option holder.

Incentive stock option. When an eligible employee is granted an incentive stock option, or when the option holder exercises the option, the option holder will generally not recognize taxable income and STATS will not receive a tax deduction, except that upon the exercise of an incentive stock option, any excess of the fair market price of the STATS ordinary shares over the exercise price constitutes a tax preference item that may have alternative minimum tax consequences for the option holder. If the option holder sells the STATS ordinary shares received pursuant to the exercise of an incentive stock option more than one year after the date of transfer of such shares and more than two years after the date of grant of the incentive stock option, the option holder will normally recognize a long-term capital gain or loss equal to the difference, if any, between the sale price of any such shares and the exercise price. If the option holder does not hold the STATS ordinary shares for the required period, when the option holder sells the shares, the option holder will recognize ordinary compensation income and possibly capital gain or loss, and STATS will generally be entitled to a U.S. federal income tax deduction in the amount of such ordinary compensation income.

The affirmative vote of a majority of the votes cast at the STATS extraordinary general meeting is required to approve STATS resolution 9.

The STATS board of directors recommends that STATS shareholders vote FOR STATS resolution 9 to approve an amendment to the STATS 1999 option plan to increase the maximum number of STATS ordinary shares issuable under the STATS 1999 option plan to 245 million STATS ordinary shares and the issuance of new STATS ordinary shares upon the exercise of options granted under the STATS 1999 option plan.

In connection with the merger, the STATS board of directors has adopted and recommends to the STATS shareholders that they approve and adopt the STATS ChipPAC ESPP, which is intended to qualify under Sections 421 and 423 of the Internal Revenue Code. The STATS board of directors believes that it is in the best interests of STATS to approve and adopt the STATS ChipPAC ESPP in order to provide employees of STATS with the opportunity to purchase STATS ordinary shares, in order to encourage broad employee ownership in STATS, encourage employees to remain in the employ of STATS, enhance the ability to attract new employees by providing an opportunity to acquire a vested interest in the success of STATS and provide a performance incentive to employees of STATS.

At the STATS extraordinary general meeting, STATS will propose that its shareholders approve and adopt the STATS ChipPAC ESPP, under which employees of STATS will be offered rights to purchase STATS ordinary shares. The following summary of the principal provisions of the STATS ChipPAC ESPP is qualified in its entirety by the specific language of the STATS ChipPAC ESPP, a copy of which is attached hereto as Annex I.

Under the STATS ChipPAC ESPP, an employee of STATS or any of its participating subsidiaries whose customary employment is for more than five calendar months per year and for at least 20 hours per week is eligible (subject to limited exceptions set forth in the Internal Revenue Code) to elect through payroll deductions or a lump sum contribution to purchase STATS ordinary shares or STATS ADSs at a discount. The STATS ChipPAC ESPP will be administered by a committee comprised of two or more members appointed by the board of directors of the combined company.

The STATS ChipPAC ESPP will be implemented by six-month purchase periods that will begin on February 15 and August 16 of each calendar year during the period that the STATS ChipPAC ESPP is in effect. A maximum aggregate of 130 million STATS ordinary shares whether issued in the form of STATS ordinary shares or STATS ADSs have been reserved for issuance under the STATS ChipPAC ESPP. The number of STATS ordinary shares available for issuance under the STATS ChipPAC ESPP will be equitably adjusted in the event of specified changes to the capitalization of STATS.

Generally, an eligible employee may elect to participate in the STATS ChipPAC ESPP for any purchase period by filing the enrollment documents by February 14 for the purchase period commencing February 15 and by August 15 for the purchase period commencing August 16. The participants will elect in the enrollment documents to pay for the purchase of STATS ordinary shares or STATS ADSs, as applicable, at the conclusion of the purchase period by either having a specified payroll deduction of 1% to 15% of his or her eligible compensation made on each payday during the purchase period or making a lump sum cash payment to be made within the last fifteen days of a purchase period (unless the administering committee prohibits a particular method of payment for any given purchase period). No participant will be granted a right to purchase STATS ordinary shares (or STATS ADSs) under the STATS ChipPAC ESPP if the participant, immediately after his or her purchase of such shares, would own STATS ordinary shares (or STATS ADSs) possessing more than 5% of the total combined voting power or value of all classes of shares of STATS or any parent or subsidiary of STATS.

A participant may not purchase STATS ordinary shares or STATS ADSs under the STATS ChipPAC ESPP having a fair market value at the time of purchase exceeding US$25,000 during any one calendar year. The maximum number of STATS ordinary shares or STATS ADSs that a participant may purchase in each purchase period may not exceed a number of shares equal to $12,500, based on the fair market value of STATS ordinary shares or STATS ADSs, as applicable, as of the first day of the purchase period rounded down to the nearest whole share, but in no event may more than 10,000 STATS ordinary shares (or 1,000 ADSs, where the participant purchases ADSs) be purchased during any given purchase period. Any amount remaining in the participant’s account after the conclusion of a purchase period that is not used to purchase STATS ordinary shares (or STATS ADSs) remains in the participant’s account to be applied to the purchase of STATS ordinary shares or STATS ADSs, as applicable, during the next purchase period.

A participant may terminate participation in the STATS ChipPAC ESPP and withdraw from an offering by submitting a withdrawal notice and receiving all of his or her accumulated payroll deductions from that purchase period. Upon withdrawal, the participant’s right to purchase STATS ordinary shares or STATS ADSs for the current purchase period will be terminated, and the participant may no longer participate in the current offering.

On the last day of the purchase period, a participant’s accumulated contributions are used to purchase STATS ordinary shares at a price equal to the lesser of (i) 85% of the fair market value of the STATS ordinary shares on the first business day of the purchase period or (ii) 85% of the fair market value of such STATS ordinary shares on the last business day of the purchase period, but in no event may the price of a STATS ordinary share be less than the par value of a STATS ordinary share.

If a participant’s employment terminates for any reason prior to the end of a purchase period, the participant’s account balance will be returned to the participant and the participant’s right to purchase STATS ordinary shares or STATS ADSs under the STATS ChipPAC ESPP will be automatically terminated.

The STATS board of directors may at any time and for any reason terminate, suspend, modify or amend the STATS ChipPAC ESPP, except that no termination or suspension of or amendment or modification to the STATS ChipPAC ESPP may adversely affect outstanding purchase rights.

The STATS ChipPAC ESPP and the right of participants to purchase STATS ordinary shares thereunder are intended to qualify under the provisions of Sections 421 and 423 of the Internal Revenue Code. Under these provisions, no income will be taxable to an employee at the time STATS ordinary shares are purchased under the STATS ChipPAC ESPP. As summarized below, an employee may be taxed upon disposition or sale of the STATS ordinary shares acquired under the STATS ChipPAC ESPP.

If the STATS ordinary shares are sold by a participant at least two years after the date on which the purchase right under the STATS ChipPAC ESPP was granted and more than one year after the transfer of the STATS ordinary shares to the participant, then the participant will recognize ordinary income in an amount equal to the lesser of (i) the excess of the fair market value of the shares on the date of grant over the purchase price of the shares or (ii) the excess of the fair market value of the shares at the time the shares are disposed of over the purchase price of the shares. Any further gain upon the sale will be treated as a capital gain. If the STATS ordinary shares are sold or otherwise disposed of by a participant and the sale price is less than the purchase price, the participant will not recognize ordinary income and the participant will recognize a capital loss equal to the difference.

The sale or other disposition of the STATS ordinary shares acquired under the STATS ChipPAC ESPP prior to the end of the second year following the first day of the applicable purchase period or prior to the end of the first year following the purchase of the shares by the participant is a “disqualifying disposition”. In the case of a disqualifying disposition, the excess of the fair market value of the STATS ordinary shares on the date the shares are purchased over the purchase price will be recognized as ordinary income to the participant in the year of sale or other disposition. Any further gain upon such sale will be treated as a capital gain. If the STATS ordinary shares are sold for less than their fair market value on the date of purchase, the same amount of ordinary income is attributed to the participant and a capital loss will be recognized equal to the difference between the sale price and the fair market value of the STATS ordinary shares on the purchase date. To the extent the participant recognizes ordinary income by reason of a disqualifying disposition, STATS will be entitled to a corresponding tax deduction for compensation in the tax year in which the disposition occurs, provided that STATS has satisfied its withholding obligations under the Internal Revenue Code.

In the event a participant dies owning STATS ordinary shares acquired under the STATS ChipPAC ESPP, compensation must be reported in his or her final income tax return. The amount of compensation to be reported will be the lesser of (a) the excess of the fair market value of the STATS ordinary shares on the date the shares were granted over the purchase price of the shares or (b) the excess of the fair market value of the shares at the time of the participant’s death over the purchase price of the shares.

At the STATS extraordinary general meeting, STATS will propose that its shareholder approve and adopt the STATS ChipPAC ESPP.

The affirmative vote of a majority of the votes cast at the STATS extraordinary general meeting is required to approve STATS resolution 10.

The STATS board of directors recommends that STATS shareholders vote FOR STATS resolution 10 to approve and adopt the STATS ChipPAC ESPP.

Resolution 11: Appoint PricewaterhouseCoopers, Singapore as auditors to STATS

At the STATS extraordinary general meeting, STATS will propose that its shareholders approve a resolution to appoint PricewaterhouseCoopers, Singapore as auditors to STATS, in place of KPMG to hold office until the conclusion of the next annual general meeting of STATS and to authorize the directors of STATS, upon the recommendation of the STATS audit committee, to fix the remuneration of PricewaterhouseCoopers, Singapore.

In light of the proposed merger, the STATS audit committee reviewed the appointment of STATS’ auditors in order to rationalize the audit services required by STATS and ChipPAC upon the consummation of the merger. The decision to review the appointment of STATS’ auditors was not related to the quality of the services provided by KPMG or any concerns raised by KPMG, nor was it motivated by a desire to realize overall cost savings. Based on this review and on conversations with KPMG, the current auditors of STATS, and PricewaterhouseCoopers, Singapore (an affiliated firm of PricewaterhouseCoopers LLP, the current auditors of ChipPAC), the STATS audit committee intends to engage PricewaterhouseCoopers, Singapore to replace KPMG as STATS’ auditors to perform the audit of its financial statements for the fiscal year 2004. PricewaterhouseCoopers, Singapore has consented to be appointed as auditors of STATS and KPMG has given notice in writing to STATS of its desire to resign as auditors of STATS and such resignation will take effect from the appointment of PricewaterhouseCoopers, Singapore at the STATS extraordinary general meeting. Prior to the decision of the STATS audit committee to recommend the engagement of PricewaterhouseCoopers, Singapore as auditors to STATS, the STATS audit committee did not discuss with PricewaterhouseCoopers, Singapore the application of accounting principles to particular transactions or the type of audit report PricewaterhouseCoopers, Singapore may give on STATS’ financial statements.

KPMG’s reports on STATS’ consolidated financial statements did not contain an adverse opinion, a disclaimer of opinion, or a qualification or modification as to uncertainty, audit scope or accounting principles. In addition, there have been no disagreements between STATS and KPMG regarding accounting principles or practices, financial statement disclosure or auditing scope or procedures that were not resolved to the satisfaction of KPMG and would require KPMG to make reference to such disagreement in its report. KPMG has not advised STATS that information has come to KPMG’s attention that has made KPMG unwilling to be associated with the STATS historical financial statements. As part of KPMG’s recent audit process, in a recent letter to the STATS audit committee KPMG noted that, in light of the complex and rapidly changing nature of the reporting environment in which STATS operates (including the significant changes to internal control documentation and reporting requirements resulting from the U.S. Sarbanes-Oxley Act) and the size and complexity of its business, a material weakness of STATS’ internal controls was resource constraints in STATS’ accounting department. KPMG recommended that STATS significantly enhance its accounting and reporting department staffing, including by hiring a Chief Financial Officer who ideally would have experience in the same capacity at a company publicly listed on a U.S. stock exchange and that uses U.S. GAAP or a partner or senior manager from an audit firm that audited such companies, or by hiring a supporting financial reporting manager or controller with similar experience. KPMG also recommended that STATS establish a corporate level accounting support group ideally including one or more U.S. certified public accountants. STATS’ audit committee and management have discussed these recommendations with KPMG and STATS intends to take prompt action to address the concern. STATS intends to add resources to its accounting staff, including retaining some of ChipPAC’s financial reporting staff. Prior to receiving the letter from KPMG, STATS had entered into an employment agreement with Mr. Michael G. Potter, the Acting Chief Financial Officer of ChipPAC, to become Chief Financial Officer of STATS upon completion of the merger. Mr. Potter will provide additional accounting resources to the combined company and enhance its U.S. GAAP reporting expertise. KPMG also noted three additional reportable conditions related to STATS’ internal controls. KPMG noted an occurrence where the STATS’ accounting department was not made aware of a sales arrangement with a significant customer on a timely basis and recommended that STATS establish a policy to involve the accounting department in the review and approval of significant new contracts. STATS has amended its contracts policy, which provides for review by STATS’ legal department and approval in accordance with authority limits, to specifically require notification and involvement of STATS’ finance department. KPMG also noted an occurrence where an erroneous manual input resulted in an overstatement of inventory and recommended that STATS review its key manual controls and implement review documentation procedures. STATS has incorporated additional controls into the inventory counting process, one of its key manual controls, and periodically reviews its key manual controls. KPMG also noted that STATS kept a significant portion of the proceeds that it raised from debt and equity offerings in November 2003 in un-hedged Singapore dollar deposits and investments and had entered into a S$10 million principal amount foreign currency derivative instrument in December 2003, exposing STATS to exchange rate fluctuations, and recommended that STATS revisit its investment policy and practices and update its guidelines

and objectives, acceptable exposures and risks, and specific approval requirements and limits based on objective, type of investment and type of risk. STATS has provided an explanation that it kept a portion of the proceeds in Singapore dollars as a natural hedge to fund its Singapore dollar requirements and that the objective of the derivative instrument, which matured in January 2004, was to increase the interest yield on such funds.

Representatives of PricewaterhouseCoopers, Singapore will be present at the STATS extraordinary general meeting, will be given an opportunity to make a statement if they desire to do so and will be available to respond to appropriate questions.

The STATS board of directors recommends that STATS shareholders vote FOR STATS resolution 11 to appoint PricewaterhouseCoopers, Singapore as auditors to STATS in place of KPMG, to hold office until the conclusion of the next annual general meeting of STATS, and to authorize the STATS board of directors, upon the recommendation of the STATS audit committee, to fix the remuneration of PricewaterhouseCoopers, Singapore.

At the STATS extraordinary general meeting, STATS will propose that its shareholders approve a resolution to change the name of STATS to “STATS ChipPAC Ltd.” and to substitute “STATS ChipPAC Ltd.” for “ST Assembly Test Services Ltd” wherever such latter name appears in the STATS memorandum of association and the STATS articles of association.

The affirmative vote of not less than three-fourths of the votes cast at the STATS extraordinary general meeting is required to approve STATS resolution 12. STATS shareholders who collectively held approximately 59.2% of the outstanding STATS ordinary shares as of June 4, 2004 have entered into the STATS voting agreement requiring them to vote all of the STATS ordinary shares and STATS ADSs owned of record by such shareholders in favor of STATS resolution 12. Therefore, based on the number of the STATS ordinary shares outstanding as of June 16, 2004 and assuming that all of such STATS ordinary shares were voted at the STATS extraordinary general meeting, only an additional 170,013,895 million STATS ordinary shares would need to be voted in favor of STATS resolution 12 to approve STATS resolution 12.

The STATS board of directors recommends that STATS shareholders vote FOR STATS resolution 12 to change the name of STATS to “STATS ChipPAC Ltd.” and to substitute “STATS ChipPAC Ltd.” for “ST Assembly Test Services Ltd” wherever such latter name appears in the STATS memorandum of association and the STATS articles of association.

The following table sets forth the name, age (as at February 15, 2004) and position of each director and member of senior management of STATS:

The following statements are summaries of STATS’ share capital structure and of the more important rights and privileges of shareholders conferred by the laws of Singapore and the STATS memorandum of association and the STATS articles of association, but are qualified by reference to the STATS memorandum of association and the STATS articles of association. The STATS memorandum of association and the STATS articles of association are available for examination at STATS’ registered office and are on file with the SEC.

The STATS ordinary shares issued in exchange for ChipPAC Class A common stock in the merger will be delivered in the form of STATS ADSs which will each represent ten STATS ordinary shares. For a description of STATS ADSs, see “Description of STATS American Depositary Shares” beginning on page 144. The rights of holders of STATS ADSs are different in some important respects from the rights of the holders of STATS ordinary shares.

STATS’ authorized capital is S$800,000,000, consisting of 3,200,000,000 STATS ordinary shares, par value S$0.25 per share. STATS has only one class of shares, namely, STATS ordinary shares, which have identical rights in all respects and rank equally with one another. The STATS articles of association provide that STATS may issue shares of a different class with preferential, deferred, qualified or other special rights, privileges or conditions as the STATS board of directors may determine and may issue preference shares which are, or at the option of STATS are, redeemable, subject to certain limitations. In addition, the STATS board of directors may issue shares at a premium. If shares are issued at a premium, a sum equal to the aggregate amount or value of the premium on the shares will, subject to certain exceptions, be transferred to a share premium account. All STATS ordinary shares are in registered form and all issued STATS ordinary shares are entitled to voting rights. STATS may, subject to and in accordance with the Singapore Companies Act, purchase STATS ordinary shares, but it may not, except as provided in the Singapore Companies Act, grant any financial assistance for the acquisition, or proposed acquisition, of STATS ordinary shares.

New STATS ordinary shares may only be issued with the prior approval of the STATS shareholders in a general meeting of the STATS shareholders. The approval, if granted, will lapse at the conclusion of the next annual general meeting held after the meeting during which the approval was granted or the date by which such annual general meeting is required to be held, whichever is earlier. STATS shareholders have given the STATS board of directors general authority to allot and issue any remaining approved but unissued ordinary shares in the capital of STATS prior to the next annual general meeting. Subject to the foregoing, the provisions of the Singapore Companies Act and any special rights attached to any class of shares currently issued, all new STATS ordinary shares are under the control of the STATS board of directors, who may allot and issue the same with such rights and restrictions as it may think fit, provided that, among other things, new STATS ordinary shares may not be issued to transfer a controlling interest in STATS without the prior approval at a general meeting of the STATS shareholders. STATS shareholders are not entitled to pre-emptive rights under the STATS articles of association or Singapore law.

Only persons who are registered in the register of members and, in cases in which the person so registered is the CDP, the persons named as depositors in the depository register maintained by the CDP for STATS ordinary shares are recognized as STATS shareholders. STATS will not, except as required by law, recognize any equitable, contingent, future or partial interest in any STATS ordinary share or other rights in respect of any STATS ordinary share other than an absolute right to the entirety thereof of the registered holder of the STATS

ordinary share or of the person whose name is entered in the depositary register for that STATS ordinary share. STATS may close the register of members for one or more periods not exceeding 30 days in the aggregate in any calendar year.

STATS is required to hold an annual general meeting every year. In addition, the STATS board of directors may convene an extraordinary general meeting whenever it thinks fit and must do so if STATS shareholders representing not less than 10% of the total voting rights of all STATS shareholders request in writing that such a meeting be held. In addition, two or more STATS shareholders holding not less than 10% of STATS issued share capital may call a meeting. Unless otherwise required by Singapore law or by the STATS articles of association, voting at general meetings is by ordinary resolution, requiring an affirmative vote of a simple majority of the votes cast at that meeting. A special resolution, requiring the affirmative vote of not less than three-fourths of the votes cast at the meeting, is necessary for certain matters under Singapore law, including the voluntary winding up of STATS, amendments to the STATS memorandum of association and the STATS articles of association, a change of the corporate name and a reduction in the share capital, share premium account or capital redemption reserve fund. STATS must give at least 21 days notice in writing for every general meeting convened for the purpose of passing a special resolution. Ordinary resolutions generally require at least 14 days notice in writing. The notice must be given to every STATS shareholder who has supplied STATS with an address in Singapore for the giving of notices and must set forth the place, the day and the hour of the meeting and, in the case of special business, the general nature of that business and a statement regarding the effect of any proposed resolution on STATS in respect of such special business.

A STATS shareholder is entitled to attend, speak and vote at any general meeting, in person or by proxy. A proxy need not be a STATS shareholder. A person who holds STATS ordinary shares through the CDP book-entry clearance system will only be entitled to vote at a general meeting if such shareholder’s name appears on the depositary register maintained by CDP 48 hours before the time of the general meeting. Except as otherwise provided in the STATS articles of association, two or more STATS shareholders holding at least 33 1/3% of the total issued and fully-paid STATS ordinary shares must be present in person or by proxy to constitute a quorum at any general meeting. Under the STATS articles of association, on a show of hands, every STATS shareholder present in person and each proxy shall have one vote. A poll may be demanded in certain circumstances, including by (i) the chairman of the meeting, (ii) not less than five STATS shareholders present in person or by proxy and entitled to vote and (iii) a STATS shareholder present in person or by proxy and representing not less than one-tenth of the total voting rights of all the shareholders having the right to vote at the meeting provided always that no poll shall be demanded on the choice of a chairman or on a question of adjournment. If a poll is called, then every STATS shareholder present in person or by proxy shall have one vote for each STATS ordinary share held or represented.

STATS may, by ordinary resolution of the STATS shareholders, declare dividends at a general meeting, but it may not pay dividends in excess of the amount recommended by the STATS board of directors. STATS must pay all dividends out of its distributable profits. However, STATS may capitalize its share premium account and apply it to pay dividends, if such dividends are satisfied by the issue of shares to the STATS shareholders. The STATS board of directors may also declare an interim dividend without the approval of the STATS shareholders. All dividends are paid pro rata among the STATS shareholders in proportion to the amount paid up on each STATS shareholder’s ordinary shares, unless the rights attaching to an issue of any STATS ordinary share provide otherwise. Unless otherwise directed, dividends are paid by check or warrant sent through the post to each STATS shareholder’s registered address. Notwithstanding the foregoing, the payment to CDP of any dividend payable to a STATS shareholder who holds STATS ordinary shares through the CDP book-entry

clearance system shall, to the extent of payment made to CDP, discharge STATS from any liability to that STATS shareholder in respect of that payment.

The STATS board of directors may, with the approval of the STATS shareholders at a general meeting, capitalize any reserves or profits (including profit or monies carried and standing to any reserve or to the share premium account) and distribute the same as bonus shares credited as paid-up to the STATS shareholders in proportion to their shareholdings. The STATS board of directors may also issue rights to take up additional STATS ordinary shares to STATS shareholders in proportion to their shareholdings. Such rights are subject to any conditions attached to such issue.

The Securities and Futures Act (Chapter 289) of Singapore (the Securities and Futures Act) and the Singapore Take-Over Code regulate the acquisition of, among other things, ordinary shares of public companies and contain certain provisions that may delay, deter or prevent a future takeover or change in control of STATS. Any person acquiring an interest, either on such person’s own or together with parties acting in concert with such person, in 30% or more of STATS voting shares, or if such person holds, either on such person’s own or together with parties acting in concert with such person, between 30% and 50% (both inclusive) of STATS voting shares, and acquires additional voting shares representing more than 1% of STATS voting shares in any six-month period, must extend a takeover offer for the remaining STATS voting shares in accordance with the provisions of the Singapore Take-Over Code. An offer for consideration other than cash must, subject to certain exceptions, be accompanied by a cash alternative at not less than the highest price paid by the offeror or parties acting in concert within the preceding six months.

“Parties acting in concert” comprise individuals or companies who, pursuant to an arrangement or understanding (whether formal or informal), co-operate, through the acquisition by any of them of shares in a company, to obtain or consolidate effective control of that company. Certain persons are presumed (unless the presumption is rebutted) to be acting in concert with each other. They are as follows: a company and its related and associated companies and companies whose associated companies include any of these companies; a company and any of its directors (including their close relatives, related trusts and companies controlled by any of the directors, their close relatives and related trusts); a company and any of its pension funds and employee share schemes; a person and any investment company, unit trust or other fund whose investment such person manages on a discretionary basis; a financial or other professional adviser and its client in respect of shares held by the adviser and persons controlling, controlled by or under the same control as the adviser and all the funds managed by the adviser on a discretionary basis, where the shareholding of the adviser and any of those funds in the client total 10% or more of the client’s equity share capital; directors of a company (including their close relatives, related trusts and companies controlled by any of such directors, their close relatives and related trusts) that is subject to an offer or where the directors have reason to believe a bona fide offer for the company may be imminent; partners; an individual and such individual’s close relatives, related trusts, any person who is accustomed to act in accordance with such individual’s instructions; and companies controlled by the individual, such individual’s close relatives, related trusts or any person who is accustomed to act in accordance with such individual’s instructions.

If a ChipPAC stockholder is in doubt as to whether he or she may incur any such takeover obligations as a result of the acquisition of STATS ordinary shares described herein, he or she should seek independent professional advice at the earliest opportunity.

If STATS liquidates or in the event of any other return of capital, holders of STATS ordinary shares will be entitled to participate in any surplus assets in proportion to their shareholdings, subject to any special rights attaching to any other class of shares.

As permitted by Singapore law, the STATS articles of association provide that, subject to the Singapore Companies Act, STATS will indemnify the STATS board of directors and officers of STATS against any liability incurred in defending any proceedings, whether civil or criminal, which relate to acts or omissions or alleged acts or alleged omissions resulting from such person’s position as an officer, director or employee of STATS. However, STATS may not indemnify directors and officers of STATS against any liability resulting from negligence, default, breach of duty or breach of trust of which they may be guilty in relation to STATS.

Except as described herein, there are no limitations imposed by Singapore law or by the STATS articles of association on the rights of nonresident shareholders to hold or vote STATS ordinary shares.

Under the Singapore Companies Act, a person has a substantial shareholding in a company if such person has an interest (or interests) in one or more voting shares in the company and the nominal amount of the shares (or the aggregate of the nominal amounts of the shares) is not less than five percent of the aggregate of the nominal amount of all voting shares in the company. A person having a substantial shareholding in STATS is required to make certain disclosures under the Singapore Companies Act and the Securities and Futures Act to STATS and to the Singapore Exchange, including the particulars of such person’s interests in STATS and the circumstances by which such person has such interests, within two business days of such person becoming a substantial shareholder of STATS and of any change in the percentage level of such person’s interest.

The rights of minority shareholders of Singapore-incorporated companies are protected under Section 216 of the Singapore Companies Act, which gives the Singapore courts a general power to make any order, upon application by any shareholder of the company, as they think fit to remedy situations where (i) the affairs of the company are being conducted or the powers of the board of directors are being exercised in a manner oppressive to, or in disregard of the interests of, one or more of the shareholders or (ii) the company takes an action, or threatens to take an action, or the shareholders pass a resolution, or propose to pass a resolution, which unfairly discriminates against, or is otherwise prejudicial to, one or more of the shareholders, including the applicant.

Singapore courts have wide discretion as to the relief that they may grant and are in no way limited to the types of relief listed in the Singapore Companies Act itself. Without prejudice to the foregoing, Singapore courts may (i) direct or prohibit any act or cancel or vary any transaction or resolution, (ii) regulate the conduct of STATS’ affairs in the future, (iii) authorize civil proceedings to be brought in the name of, or on behalf of, STATS by a person or persons, (iv) on such terms as the court may direct, provide for the purchase of a minority shareholder’s shares by other STATS shareholders or by STATS, (v) in the case of a purchase of shares by STATS, a corresponding reduction of the share capital, (vi) provide that the STATS memorandum of association or STATS articles of association be amended or (vii) provide that STATS be wound up.

The transfer agent and registrar for the STATS ordinary shares is M&C Services Pte Ltd.

American Depositary Shares, or ADSs, represent ownership interests in securities that are on deposit with a depositary bank. Citibank, N.A., located at 111 Wall Street, New York, New York 10043, acts as the depositary for STATS ADSs. ADSs are normally represented by certificates that are commonly known as American Depositary Receipts, or ADRs. The STATS depositary typically appoints a custodian to safekeep the securities on deposit. The custodian for the securities on deposit is Citibank Nominees Singapore Pte Ltd (the custodian), located at 300 Tampines Avenue #07-00, Tampines Junction, Singapore 529653.

STATS has appointed Citibank, N.A., as depositary pursuant to the STATS deposit agreement. A copy of the STATS deposit agreement is on file with the SEC under cover of a registration statement on Form F-6. You may obtain a copy of the STATS deposit agreement from the SEC’s Public Reference Room at 450 Fifth Street, N.W., Washington, D.C. 20549. See “Where You Can Find More Information” beginning on page 181.

Each STATS ADS represents ten STATS ordinary shares on deposit with the custodian. A STATS ADS also represents any other property received by the STATS depositary or the custodian on behalf of the STATS ADS holders that has not been distributed to the STATS ADS holders because of legal restrictions or practical considerations.

A holder of STATS ADSs and each beneficial owner, upon acceptance of any ADS or any interest therein, is deemed to be a party to the STATS deposit agreement and is bound to its terms and to the terms of the STATS ADR that represents the holder’s STATS ADSs. The STATS deposit agreement and the STATS ADR specify the rights and obligations of STATS, as well as the rights and obligations of holders of STATS ADSs and those of the STATS depositary. Each STATS ADS holder is deemed to have appointed the STATS depositary as its attorney-in-fact with full power to act on such holder’s behalf in certain circumstances. Although the STATS deposit agreement is governed by New York law, STATS’ obligations to the holders of STATS ordinary shares are governed by the laws of Singapore, which may be different from the laws in the United States.

A holder of STATS ADSs may hold STATS ADSs either by means of an STATS ADR registered in the holder’s name or through a brokerage or safekeeping account. If a holder holds STATS ADSs through a brokerage or safekeeping account, such holder must rely on the procedures of the broker or bank to assert the holder’s rights as an STATS ADS holder.

STATS ADSs have been quoted on the Nasdaq National Market since January 28, 2000. As of June 16, 2004, 1,197,230 STATS ADSs (representing 11,972,300 STATS ordinary shares), representing 1.1% of the outstanding STATS ordinary shares, were held by a total of four registered holders of record with addresses in the United States. Because many of STATS ordinary shares and STATS ADSs are held by brokers and other institutions on behalf of shareholders in street name, STATS believes that the number of beneficial holders of the STATS ordinary shares and STATS ADSs is substantially higher.

The following summary description assumes the STATS ADS holder has opted to own the STATS ADSs directly by means of a STATS ADR registered in the holder’s name. Please note that the rights and obligations of a holder of STATS ADSs is determined by the STATS deposit agreement and not by this summary. Shareholders of STATS and ChipPAC are urged to review the STATS deposit agreement in its entirety, as well as the form of STATS ADR attached to the STATS deposit agreement.

The STATS depositary may create STATS ADSs on a holder’s behalf if the holder or the holder’s broker deposits STATS ordinary shares with the custodian. The STATS depositary will deliver the STATS ADSs to the

person indicated only upon satisfaction of the terms provided in the STATS deposit agreement and only after receiving any applicable issuance fees, any charges and taxes payable to the STATS depositary in connection with such transfer of STATS ordinary shares and issuance of STATS ADSs.

The issuance of STATS ADSs may be delayed until the STATS depositary or the custodian receives confirmation that all required approvals have been given and that the STATS ordinary shares have been duly transferred to the custodian. The STATS depositary will only issue STATS ADSs in whole numbers.

When a person makes a deposit of STATS ordinary shares, such person is responsible for transferring good and valid title to the STATS depositary. Such person is deemed to represent and warrant that:

If any of the representations or warranties is incorrect in any way, STATS and the STATS depositary may, at the cost and expense of the person depositing the STATS ordinary shares, take any and all actions necessary to correct the consequences of the misrepresentations.

Subject to the terms of the STATS deposit agreement, a holder of STATS ADSs is entitled to present the STATS ADSs owned by such holder to the STATS depositary for cancellation and then receive the underlying STATS ordinary shares at the custodian’s principal office. In order to withdraw the STATS ordinary shares represented by STATS ADSs, a holder is required to pay to the STATS depositary the fees for cancellation of STATS ADSs and any charges and taxes payable upon the transfer of the STATS ordinary shares being withdrawn. The holder assumes the risk for delivery of all funds and securities upon withdrawal. Once canceled, the STATS ADSs no longer have any of the rights they may previously have had under the STATS deposit agreement.

The STATS depositary may ask a holder of a STATS ADR in whose name the STATS ADR is registered to provide proof of identity and genuineness of any signature and certain other documents as the STATS depositary may deem appropriate before it will cancel any STATS ADSs. The withdrawal of the STATS ordinary shares represented by STATS ADSs may be delayed until the STATS depositary receives satisfactory evidence of compliance with all applicable laws and regulations. As noted above, the STATS depositary will only accept STATS ADSs for cancellation that represent a whole number of securities on deposit.

A holder has the right to withdraw the STATS ordinary shares represented by such holder’s STATS ADSs at any time subject to:

The STATS deposit agreement may not be modified to impair a STATS ADS holder’s right to withdraw the securities represented by such holder’s STATS ADSs except to comply with mandatory provisions of law.

A holder of STATS ADSs generally has the right to receive distributions made by STATS on the securities deposited with the custodian. A STATS ADS holder’s receipt of these distributions may be limited, however, by practical considerations and legal limitations. Holders will receive such distributions subject to the terms of the STATS deposit agreement and Singapore law in proportion to the number of STATS ADSs held as of a specified record date.

Whenever STATS makes a cash distribution for the securities on deposit with the custodian, the custodian confirms receipt of such cash distribution with the STATS depositary. Upon receipt of such confirmation, the STATS depositary arranges for the funds to be converted into U.S. dollars and for the distribution of the U.S. dollars to holders.

The conversion into U.S. dollars takes place only if practicable in the reasonable judgment of the STATS depositary and if the U.S. dollars are transferable to the United States. The amounts distributed to holders is net of the fees, expenses, taxes and governmental charges payable by holders under the terms of the STATS deposit agreement. The STATS depositary applies the same method for distributing the proceeds of the sale of any property, such as undistributed rights, held by the custodian in respect of securities on deposit.

Whenever STATS makes a dividend in, or a free distribution of, STATS ordinary shares for the securities on deposit with the custodian, the custodian confirms such deposit with the STATS depositary. Upon receipt of such confirmation, the STATS depositary either distributes to holders new STATS ADSs representing the STATS ordinary shares deposited or modifies the ADS-to-ordinary share ratio, in which case each STATS ADS held represents rights and interests in the additional STATS ordinary shares so deposited. Only whole new STATS ADSs will be distributed. Fractional entitlements will be sold and the proceeds of such sale will be distributed as in the case of a cash distribution.

The distribution of new STATS ADSs or the modification of the ADS-to-ordinary share ratio upon a distribution of STATS ordinary shares is made net of the fees, expenses, taxes and governmental charges payable by holders under the terms of the STATS deposit agreement. In order to pay such taxes or governmental charges, the STATS depositary may sell all or a portion of the new STATS ordinary shares so distributed.

New STATS ADSs are not distributed if it would violate a law (i.e., the U.S. securities laws) or if it is not operationally practicable. If the STATS depositary does not distribute new STATS ADSs as described above, it will use its best efforts to sell the STATS ordinary shares received and will distribute the proceeds of the sale as in the case of a distribution of cash.

Whenever STATS intends to distribute a dividend payable at the election of STATS ordinary shareholders either in cash or in additional shares, STATS will give prior notice thereof to the STATS depositary and will indicate whether it wishes the distribution to be made available to STATS ADS holders. In such case, STATS will assist the STATS depositary in determining whether such distribution is lawful and reasonably practical.

The STATS depositary will make the election available to STATS ADS holders only if it is reasonably practical and if STATS has provided to the STATS depositary all of the documentation contemplated in the STATS deposit agreement. In such case, the STATS depositary will establish procedures to enable STATS ADS holders to elect to receive either cash or additional STATS ADSs, in each case as described in the STATS deposit agreement.

If the election is not made available to a STATS ADS holder, such holder will receive either cash or additional STATS ADSs, depending on what a STATS ordinary shareholder in Singapore would receive for failing to make an election, as more fully described in the STATS deposit agreement.

Whenever STATS intends to distribute rights to purchase additional STATS ordinary shares, STATS will give prior notice to the STATS depositary and will assist the STATS depositary in determining whether it is lawful and reasonably practicable to distribute to holders of STATS ADS rights to purchase additional STATS ADSs.

The STATS depositary will establish procedures to distribute rights to purchase additional STATS ADSs to holders and to enable such holders to exercise such rights if it is lawful and reasonably practicable to make the rights available to holders of STATS ADSs. Upon the exercise of any such rights, a holder of STATS ADSs may have to pay fees, expenses, taxes and other governmental charges to subscribe for the new STATS ADSs. The STATS depositary is not obligated to establish procedures to facilitate the distribution and exercise of such rights.

The STATS depositary will not distribute the rights to a holder of STATS ADSs if:

The STATS depositary will sell any rights that are not exercised or distributed if such sale is lawful and reasonably practicable. The proceeds of such sale will be distributed to holders of STATS ADSs as in the case of a cash distribution. If the STATS depositary is unable to sell the rights, it will allow the rights to lapse, in which case a holder of STATS ADSs will receive no value for such rights.

Whenever STATS intends to distribute property other than cash, shares or rights to purchase additional STATS ordinary shares, STATS will notify the STATS depositary in advance and will indicate whether it wishes such distribution to be made to holders of STATS ADSs. If so, STATS will assist the STATS depositary in determining whether such distribution to holders of STATS ADSs is lawful and reasonably practicable.

If it is reasonably practicable to distribute such property to a holder of STATS ADSs and if STATS provides the STATS depositary with all of the documentation contemplated in the STATS deposit agreement, the STATS depositary will distribute the property to the holder of STATS ADSs in a manner it deems reasonably practicable.

The distribution will be made net of fees, expenses, taxes and governmental charges payable by holders under the terms of the STATS deposit agreement. In order to pay such taxes and governmental charges, the STATS depositary may sell all or a portion of the property received.

The STATS depositary will not distribute the property to a holder of STATS ADSs and will sell the property if:

The proceeds of such a sale will be distributed to holders of STATS ADSs as in the case of a cash distribution.

Whenever STATS decides to redeem any of the securities on deposit with the custodian, STATS will notify the STATS depositary. If it is reasonably practicable and if STATS provides the STATS depositary with all of the documentation contemplated in the STATS deposit agreement, the STATS depositary will mail notice of the redemption to the holders of STATS ADSs.

The custodian will be instructed to surrender the STATS ordinary shares being redeemed against payment of the applicable redemption price. The STATS depositary will convert the redemption funds received into U.S. dollars upon the terms of the STATS deposit agreement and will establish procedures to enable holders of STATS ADSs to receive the net proceeds from the redemption upon surrender of their STATS ADSs to the STATS depositary. Holders of STATS ADSs may have to pay fees, expenses, taxes and other governmental charges upon the redemption of their STATS ADSs. If less than all STATS ADSs are being redeemed, the STATS ADSs to be retired will be selected by lot or on a pro rata basis, as the STATS depositary may determine.

The STATS ordinary shares held on deposit for a holder’s STATS ADSs may change from time to time. For example, there may be a change in nominal or par value, a split-up, stock split (either forward or reverse), cancellation, consolidation or reclassification of such STATS ordinary shares or a recapitalization, reorganization, merger, consolidation or sale of assets.

If any such change were to occur, a holder’s STATS ADSs would, to the extent permitted by law, represent the right to receive the property received or exchanged in respect of the STATS ordinary shares held on deposit. The STATS depositary may in such circumstances deliver new STATS ADSs to such holder or call for the exchange of such holder’s existing STATS ADSs for new STATS ADSs. If the STATS depositary may not lawfully distribute such property to a holder of STATS ADSs, the STATS depositary may sell such property and distribute the net proceeds to the holder as in the case of a cash distribution.

Holders of STATS ADSs generally have the right under the STATS deposit agreement to instruct the STATS depositary to exercise the voting rights for the STATS ordinary shares represented by the STATS ADSs. The STATS depositary must mail to holders of STATS ADSs any notice of a shareholders’ meeting received from STATS 21 days prior to such meeting, together with information explaining how to instruct the STATS depositary to exercise the voting rights of the securities represented by STATS ADSs. If the STATS depositary timely receives voting instructions from a holder of STATS ADSs, it will endeavor to vote the securities represented by the holder’s STATS ADSs in accordance with such voting instructions.

Please note that the ability of the STATS depositary to carry out voting instructions may be limited by practical and legal limitations and the terms of the securities on deposit. STATS cannot assure holders of STATS ADSs that they will receive voting materials in time to enable such holders of STATS ADSs to return voting instructions to the STATS depositary in a timely manner. Securities for which no voting instructions have been received will not be voted.

A STATS ADS holder is required to pay the following service fees to the STATS depositary:

For a period of ten business days after the closing of the merger, the service fee payable to the STATS depositary for the delivery of STATS ordinary shares upon the surrender of STATS ADSs will be reduced to 2.5 cents from 5 cents per surrendered STATS ADS. STATS ADS holders will remain responsible for the other customary fees, expenses, taxes and governmental charges described below.

STATS ADS holders are responsible to pay certain fees and expenses incurred by the STATS depositary and certain taxes and governmental charges such as:

STATS has agreed to pay certain other charges and expenses of the STATS depositary. Please note that the fees and charges holders may be required to pay may vary over time and may be changed by STATS and by the STATS depositary. Holders will receive prior notice of such changes.

STATS may agree with the STATS depositary to modify the STATS deposit agreement at any time without the consent of holders of STATS ADSs. Any modifications of the STATS deposit agreement that would materially prejudice any of the substantial existing rights of holders under the STATS deposit agreement (except in very limited circumstances enumerated in the STATS deposit agreement) will not become effective as to outstanding STATS ADS holders for 30 days after notice of such modification is given to holders of STATS ADSs.

A holder of STATS ADSs will be bound by the modifications to the STATS deposit agreement if such holder of STATS ADSs continues to hold STATS ADSs after the modifications to the STATS deposit agreement become effective. The STATS deposit agreement cannot be amended to prevent a holder of STATS ADSs from withdrawing the STATS ordinary shares represented by such holder’s STATS ADSs, except as permitted by law.

STATS has the right to direct the STATS depositary to terminate the STATS deposit agreement. Similarly, the STATS depositary may, in certain circumstances, on its own initiative terminate the STATS deposit agreement. In either case, the STATS depositary must give notice to the holders of STATS ADSs at least 30 days before termination.

The STATS depositary maintains STATS ADS holder records at its depositary office. Holders of STATS ADSs may inspect these records at such office during regular business hours but solely for the purpose of communicating with other holders of STATS ADSs in the interest of business matters relating to the STATS ADSs and the STATS deposit agreement.

The STATS depositary maintains facilities in New York to record and process the issuance, cancellation, combination, split-up and transfer of STATS ADRs. These facilities may be closed from time to time, subject to applicable law.

The STATS deposit agreement limits STATS’ obligations and the STATS depositary’s obligations to holders of STATS ADSs. STATS and the STATS depositary are obligated only to take the actions specifically stated in the STATS deposit agreement without negligence or bad faith. Such actions include the following:

The STATS depositary may, in certain circumstances, issue STATS ADSs before receiving a deposit of STATS ordinary shares or release STATS ordinary shares before receiving STATS ADSs. These transactions are commonly referred to as “pre-release transactions”. The STATS deposit agreement limits the aggregate size of pre-release transactions and imposes a number of conditions on such transactions, including the need to receive collateral, the type of collateral required and the representations required from brokers. The STATS deposit agreement requires the STATS ADSs to be fully collateralized before any STATS ADSs are pre-released. The STATS depositary may retain the compensation received from the pre-release transactions.

STATS ADS holders are responsible for the taxes and other governmental charges payable on the STATS ADSs and the securities represented by the STATS ADSs. STATS, the STATS depositary and the custodian may deduct from any distribution the taxes and governmental charges payable by holders of STATS ADSs and may sell any and all property on deposit to pay the taxes and governmental charges payable by holders of STATS ADSs. Holders of STATS ADSs are liable for any deficiency if the sale proceeds do not cover the taxes that are due.

The STATS depositary may refuse to issue STATS ADSs, to deliver, transfer, split and combine STATS ADRs or to release securities on deposit until all taxes and charges are paid by the applicable holder of STATS ADSs. The STATS depositary and the custodian may take reasonable administrative actions to obtain tax refunds and reduced tax withholding for any distributions on a holder’s behalf. However, holders of STATS ADSs may be required to provide to the STATS depositary and to the custodian proof of taxpayer status and residence and such other information as the STATS depositary and the custodian may require to fulfill legal obligations. A holder of STATS ADSs is required to indemnify STATS, the STATS depositary and the custodian for any claims with respect to taxes based on any tax benefit obtained for such holder.

The STATS depositary will arrange for the conversion of all foreign currency received into U.S. dollars if such conversion is practical, and it will distribute the U.S. dollars in accordance with the terms of the STATS deposit agreement. A holder of STATS ADSs may have to pay fees and expenses incurred in converting foreign currency, such as fees and expenses incurred in complying with currency exchange controls and other governmental requirements.

If the conversion of foreign currency is not practical or lawful, or if any required approvals are denied or not obtainable at a reasonable cost or within a reasonable period, the STATS depositary may take the following actions in its discretion:

STATS is a public company limited by shares incorporated under the laws of Singapore. The rights of holders of STATS ordinary shares are governed by Singapore law and by the STATS memorandum of association and the STATS articles of association. STATS is subject to the continuing listing rules of the Nasdaq National Market and applicable U.S. federal securities laws and is not subject to the continuing listing rules of the Singapore Exchange.

ChipPAC is a corporation incorporated under the laws of the State of Delaware. The rights of holders of ChipPAC Class A common stock are governed by Delaware law and by the ChipPAC certificate of incorporation and the ChipPAC bylaws.

If the merger is completed, the holders of ChipPAC Class A common stock will become holders of STATS ADSs, each of which represents the right to receive ten STATS ordinary shares as described in “Description of STATS American Depositary Shares” beginning on page 144. The rights of holders of STATS ADSs are governed by the STATS deposit agreement and the rights of holders of the underlying STATS ordinary shares are governed by Singapore law and by the STATS memorandum of association and the STATS articles of association. There are a number of differences between the rights of holders of ChipPAC Class A common stock and the rights of holders of STATS ADSs or holders of STATS ordinary shares arising from the differences between the corporate laws of Delaware and of Singapore and the governing organizational documents of the two companies. The rights of holders of STATS ADSs to receive STATS ordinary shares is described in “Description of STATS American Depositary Shares” beginning on page 144.

While STATS and ChipPAC believe that the following description covers the material differences between the two companies’ governing laws and organizational documents, this summary may not contain all of the information that is important. This summary is not intended to be a complete discussion and it is qualified in its entirety by applicable Singapore and Delaware law and the governing organizational documents of STATS and ChipPAC. The following summary, as well as the other documents referred to in this summary, should be read carefully for a more complete understanding of the differences between the rights of a holder of ChipPAC Class A common stock and a holder of STATS ordinary shares. For a description of the rights of the holders of STATS ordinary shares and STATS ADSs see “Description of STATS Ordinary Shares” and “Description of STATS American Depositary Shares” on pages 140 and 144, respectively.

STATS’ and ChipPAC’s respective governing organizational documents are on file with the SEC and will be sent to you upon request. See “Where You Can Find More Information” on page 181. The following is a summary of certain material differences between the rights of holders of STATS ordinary shares and holders of ChipPAC Class A common stock:

The following unaudited pro forma condensed combined consolidated financial statements give effect to the proposed merger between STATS and ChipPAC using the purchase method of accounting for the business combination.

Upon completion of the merger, holders of ChipPAC Class A common stock will be entitled to receive 0.87 (the exchange ratio) of a STATS ADS in exchange for each share of ChipPAC Class A common stock owned at the time of the consummation of the merger. The exchange ratio will be proportionately adjusted for any stock split, stock dividend, reorganization or similar change in ChipPAC Class A common stock or STATS ordinary shares. ChipPAC stockholders will receive cash based on the market price of STATS ADSs in lieu of any fractional shares to which they might otherwise be entitled.

The actual number of STATS ADSs to be issued in the merger and the dollar value at the effective time of the merger cannot be determined until the closing date of the merger. The unaudited pro forma condensed combined consolidated financial statements were prepared based on the number of shares of ChipPAC Class A common stock outstanding as of March 31, 2004.

The unaudited pro forma condensed combined consolidated statement of operations gives effect to the proposed merger as if it had been consummated on January 1, 2003. The unaudited pro forma condensed combined consolidated statement of operations data combines the historical consolidated statement of operations of STATS for the year ended December 31, 2003 and the three months ended March 31, 2004 with the historical consolidated statement of operations of ChipPAC for the year ended December 31, 2003 and the three months ended March 31, 2004, after giving effect to adjustments arising from applying the purchase method of accounting.

The unaudited pro forma condensed combined consolidated balance sheet gives effect to the proposed merger as if it had been consummated on March 31, 2004. The unaudited pro forma condensed combined consolidated balance sheet combines the historical consolidated balance sheet of STATS as of March 31, 2004 with the historical consolidated balance sheet of ChipPAC as of March 31, 2004, after giving effect to adjustments arising from applying the purchase method of accounting.

The accompanying unaudited pro forma condensed combined consolidated financial statements are presented in accordance with Article 11 of Regulation S-X. The pro forma information is presented for illustrative purposes only and is not necessarily indicative of the operating results or financial position that would have occurred if the proposed merger had been consummated on January 1, 2003 or March 31, 2004, nor is it necessarily indicative of the future operating results or financial position of the combined company. See “Forward-Looking Statements” on page 28. The unaudited pro forma condensed combined consolidated financial statements are based on STATS management’s preliminary estimates of, and good faith assumptions regarding, the adjustments arising from the proposed merger at the time of the filing of this document. A preliminary valuation was conducted in order to assist STATS management in determining the fair values of a significant portion of ChipPAC’s assets and was considered by STATS management in estimating the fair values of ChipPAC’s assets reflected in the unaudited pro forma condensed combined consolidated financial statements. The preliminary valuation and the pro forma adjustments are based upon the limited information currently made available to STATS by ChipPAC for purposes of conducting a valuation of ChipPAC’s assets and liabilities. Not all information required to complete such a valuation is currently available to STATS, due to, among other things, regulatory restrictions and other considerations regarding the sharing of certain information between possible competitors prior to the consummation of the merger and as additional information becomes available to

STATS, the actual allocation of the merger consideration to the ChipPAC assets acquired and liabilities assumed upon the consummation of the merger could differ materially from current estimates and may include allocation of amounts to in-process research and development. Any amount allocated to in-process research and development will be expensed by the combined company in the quarter in which the merger is completed. A final determination of the fair value of the ChipPAC assets and liabilities cannot be made prior to the consummation of the merger. Therefore, the actual amounts recorded as of the completion of the merger may differ materially from the information presented in these unaudited pro forma condensed combined consolidated financial statements. The pro forma financial statements should be read in conjunction with the accompanying notes thereto and with STATS’ and ChipPAC’s historical consolidated financial statements and related notes thereto incorporated by reference into this document.

See accompanying notes to unaudited pro forma condensed combined financial statements.

On February 10, 2004, STATS and ChipPAC entered into a merger agreement which will result in ChipPAC becoming a wholly owned subsidiary of STATS in a transaction to be accounted for using the purchase method.

The unaudited pro forma condensed combined consolidated financial statements assume the issuance of approximately 86 million STATS ADSs in the merger, based upon the exchange ratio of 0.87 STATS ADSs for each share of ChipPAC Class A common stock and the number of outstanding shares of ChipPAC Class A common stock as of March 31, 2004. The actual number of STATS ADSs to be issued will be determined based upon the actual number of shares of ChipPAC Class A common stock outstanding at the effective time of the merger. The average market price per STATS ADS of $12.402 is based upon an average of the closing prices for a range of trading days (February 8 through 12, 2004) around February 10, 2004, the date on which the proposed merger was announced.

The fair values of STATS substitute options, both vested and unvested, were determined using a Black-Scholes valuation model with the following assumptions: no dividend yield; an expected volatility of 61.87%, and a risk-free interest rate of 2.78%. The model assumed an expected life of 7 years for vested and unvested options.

Based upon the total number of shares of ChipPAC Class A common stock subject to outstanding ChipPAC options as of March 31, 2004, STATS would issue, in connection with the merger, STATS substitute options to acquire approximately 80.96 million STATS ordinary shares at a weighted average exercise price of $0.55 per STATS ordinary share. The actual number of STATS ordinary shares that would be subject to STATS substitute options that will be issued in connection with the merger would be based upon the actual number of shares of ChipPAC Class A common stock subject to outstanding ChipPAC options at the effective time of merger.

The estimated total purchase price of the ChipPAC acquisition is as follows (in thousands):

Under the purchase method of accounting, the total estimated purchase price as shown in the table above is allocated to ChipPAC’s net tangible and identifiable intangible assets based on their estimated fair values as of the date of the consummation of the merger. In determining the preliminary price allocation, STATS management considered, among other factors, its intention for use of acquired assets as well as historical demand and estimates of future demand for ChipPAC’s products and services. Based on these assumptions and subject to changes to other factors as described in the introduction to these unaudited pro forma condensed combined consolidated financial statements on page 169 of this document, the preliminary estimated purchase price is allocated as follows (in thousands):

Of the total estimated purchase price, a preliminary estimate of $45.3 million has been allocated to net liabilities assumed and approximately $131.7 million has been allocated to amortizable identifiable intangible assets acquired. The depreciation and amortization related to the fair value adjustment to net tangible assets and the amortization related to the amortizable intangible assets are reflected as pro forma adjustments to the unaudited pro forma condensed combined consolidated statements of operations.

The fair value of tangible assets was estimated primarily based on the cost and sales comparison approaches. In applying the cost approach, the replacement or reproduction cost estimates for the buildings, machinery and other equipment were based on indexed original costs or manufacturer reported replacement costs. Original historical cost data was segregated by appraisal class and year of acquisition, and indexed to estimated reproduction cost. Inflation trend factors were derived using indices from nationally recognized indexes. Replacement or reproduction costs were reduced by depreciation factors that reflect the estimated physical deterioration and functional obsolescence of assets. The sales comparison approach was used for tangible assets that have an active resale market. Similar assets recently sold or offered for sale were analyzed and their prices adjusted to reflect the difference between the comparable asset and the asset and the conditions of the sale to estimate the value of the acquired assets.

The fair value assigned to intangible assets were estimated by discounting the estimated future cash flows of the intangibles assets to their present value. The cash flow estimates used for technology and intellectual property were based on estimates of product revenue and appropriate royalty rates (based on an analysis of rates for similar technologies and forecast product margins). The cash flow estimates used for customer relationships were based on estimates of revenue attributed to the current customers and the programs they have been qualified on as well as the profitability attributed to each. The rate used to discount these net cash flows was determined after consideration of market returns on debt and equity capital, the weighted average return on invested capital, the nature of each asset and the risk associated with achieving the forecast.

The combined company expects to amortize the fair value of the ChipPAC tradename on a straight-line basis over an average estimated life of 7 years.

Technology and intellectual property relates to ChipPAC’s technology for Ball Grid Array, Leadframe and Chip Scale Package. The combined company expects to amortize the fair value of these assets on a straight-line basis over an average estimated life of 10 years.

Customer relationships represent those customers with which ChipPAC has current sales relationships. The combined company expects to amortize the fair value of these assets on a straight-line basis over an average estimated life of 3 years.

Of the total estimated purchase price, approximately $1,044.5 million has been allocated to goodwill. Goodwill represents the excess of the purchase price of an acquired business over the fair value of the underlying net tangible and identifiable intangible assets.

In accordance with the Statement of Financial Accounting Standards No. 142, “Goodwill and Other Intangible Assets,” goodwill and intangible assets with indefinite lives resulting from business combinations completed subsequent to June 30, 2001 will not be amortized but instead will be tested for impairment at least annually (more frequently if certain indicators are present). In the event that the management of the combined company determines that the value of goodwill or intangible assets with indefinite lives has become impaired, the combined company will incur an accounting charge for an amount of the impairment during the fiscal quarter in which the determination is made.

The unaudited pro forma condensed combined consolidated financial statements reflects how the merger might have affected STATS’ historical financial statements had the merger been consummated at an earlier time. The pro forma adjustments related to the unaudited pro forma condensed combined consolidated statement of operations assume the merger was consummated as of January 1, 2003. The pro forma adjustments related to the unaudited pro forma combined condensed consolidated balance sheet assume the merger was consummated as of March 31, 2004. The assumptions involved in the pro forma adjustments to the unaudited pro forma condensed combined consolidated financial statements are explained in Note 2, below.

Pro forma adjustments are necessary to reflect the estimated purchase price, to adjust amounts related to net tangible and intangible assets acquired and liabilities assumed to a preliminary estimate of their fair values, to reflect the amortization expense related to the estimated amortizable intangible assets, to reflect changes in depreciation and amortization expense resulting from the estimated fair value adjustments to net tangible assets, to reflect the impact on interest expense of the amortization of the fair value adjustment to long-term debt and to reflect the income tax effect related to the pro forma adjustments.

No pro forma adjustments were required to conform ChipPAC’s accounting policies to STATS’ accounting policies. Certain reclassifications have been made to conform ChipPAC’s historical amounts to STATS’ presentation.

The pro forma combined provision for income taxes does not reflect the amounts that would have resulted had STATS and ChipPAC filed consolidated income tax returns during the periods presented.

The pro forma adjustments included in the unaudited pro forma condensed combined consolidated financial statements are as follows:

The pro forma basic and diluted earnings per STATS ordinary share and earnings per STATS ADS are based on the weighted average number of shares of STATS ordinary shares and STATS ADSs outstanding during each period and weighted average number of ChipPAC Class A common stock outstanding during each period multiplied by the exchange ratio. The substitution of ChipPAC options with STATS substitute options is not reflected in pro forma earnings because the effect would be antidilutive.

Note 4 Liabilities under the ChipPAC, Inc. Employee Retention and Severance Plan

Certain employees of ChipPAC will receive payments under the ChipPAC employee retention plan. The unaudited pro forma condensed combined consolidated financial statements do not include any adjustments for liabilities relating to the retention of the employees. The estimated liabilities assumed of $1.23 million to be incurred in the first year of the merger will be recorded upon completion of the merger.

If the merger is not completed, ChipPAC will hold a 2004 Annual Meeting of Stockholders. If this meeting is held, the ChipPAC board of directors will consider proposals of stockholders intended to be presented for action at the annual meeting of stockholders. A stockholder proposal must be submitted in writing and be received at ChipPAC’s principal executive offices, 47400 Kato Road, Fremont, California 94538, Attn: Secretary. ChipPAC will announce the deadline for stockholders to submit proposals a reasonable period of time preceding the mailing of this document. In the event the merger is completed, there will not be an annual meeting of ChipPAC stockholders.

The validity of the STATS ADSs to be issued in connection with the merger and the underlying STATS ordinary shares will be passed upon for STATS by Allen & Gledhill. In addition, Shearman & Sterling LLP will pass upon certain United States federal income tax consequences of the merger to ChipPAC stockholders. Kirkland & Ellis LLP will pass upon certain United States federal income tax consequences of the merger to ChipPAC stockholders.

(b) At the Effective Time, the By-laws of Merger Sub, as in effect immediately prior to the Effective Time, shall be the By-laws of the Surviving Corporation until thereafter amended as provided by law, the Certificate of Incorporation of the Surviving Corporation and such By-laws.

SECTION 2.01. Conversion of Securities. At the Effective Time, by virtue of the Merger and without any action on the part of any party:

(a) each share of class A common stock, par value $0.01 per share, of the Company (“Company Class A Common Stock”) (all shares of Company Class A Common Stock issued and outstanding immediately prior to the Effective Time being hereinafter collectively referred to as the “Company Shares”) issued and outstanding immediately prior to the Effective Time (other than any Company Shares to be canceled pursuant to Section 2.01(b)) shall be canceled and shall be converted automatically, subject to Section 2.02, into the right to receive 0.87 (the “Exchange Ratio”) Parent ADSs. The Parent ADSs may be evidenced by one or more Parent ADRs (as defined in Section 9.03(a)) issued in accordance with the Parent Deposit Agreement (as defined in Section 9.03(a)). The Parent ADSs to be issued upon conversion of Company Shares pursuant to this Section 2.01(a) and any cash to be paid in lieu of fractional Parent ADSs as contemplated in Section 2.02(e) are referred to collectively as “Merger Consideration”. Such Parent ADSs and the underlying Parent Ordinary Shares shall be in the same class and of the same ranking as currently outstanding Parent ADSs and Parent Ordinary Shares;

(b) each Company Share held in the treasury of the Company and each Company Share owned by Merger Sub, Parent or any direct or indirect wholly owned subsidiary of Parent or of the Company immediately prior to the Effective Time (collectively, the “Excluded Company Shares”) shall be canceled without any conversion thereof and no payment or distribution shall be made with respect thereto; and

(c) each share of common stock, par value $0.01 per share, of Merger Sub issued and outstanding immediately prior to the Effective Time shall be converted into and exchanged for one validly issued, fully paid and nonassessable share of common stock, par value $0.01 per share, of the Surviving Corporation (“Surviving Corporation Common Stock”).

SECTION 2.02. Exchange of Certificates. (a) Exchange Agent. (i) Prior to the Effective Time, Parent shall appoint a bank or trust company reasonably acceptable to the Company as exchange agent (the “Exchange Agent”) for the purpose of accepting Certificates (as defined below) to be surrendered by holders of Company Shares in exchange for the Merger Consideration. Promptly after the Effective Time, the Surviving Corporation will mail, or shall cause the Exchange Agent to mail, to each person who was, at the Effective Time, a holder of record of Company Shares entitled to receive the Merger Consideration pursuant to Section 2.01(a): (A) a letter of transmittal, which shall be in customary form and shall specify that delivery shall be effected, and risk of loss and title to the certificates evidencing such Company Shares (the “Certificates”) shall pass, only upon proper delivery of the Certificates to the Exchange Agent and (B) instructions for use in effecting the surrender of the Certificates pursuant to such letter of transmittal.

(ii) At the Effective Time, Parent shall issue to and deposit with the Depositary, for the benefit of the holders of Company Shares converted into the right to receive Parent ADSs in accordance with Section 2.01(a), Parent Ordinary Shares in an amount sufficient to permit the Depositary to issue Parent ADRs representing the number of Parent ADSs issuable pursuant to Section 2.01(a). Parent shall cause the Depositary to issue, upon the instructions of the Exchange Agent, for the benefit of the holders of Company Shares converted into the right to receive Parent ADSs in accordance with Section 2.01(a), through the Exchange Agent, Parent ADRs representing the number of Parent ADSs issuable pursuant to Section 2.01(a).

(b) Exchange Procedures. Upon surrender to the Exchange Agent of a Certificate for cancellation, together with a letter of transmittal, duly completed and validly executed in accordance with the instructions thereto and covering the Company Shares represented by such Certificate, and such other documents as may be required pursuant to the instructions to the letter of transmittal, the holder of such Certificate shall be entitled to receive in exchange therefor (i) the number of whole Parent ADSs (excluding any fractional interest in Parent ADSs) to which such holder is entitled in respect of such Company Shares pursuant to Section 2.01(a), and (ii) a check in the amount (after giving effect to any required Tax withholdings) equal to (A) any cash in lieu of fractional interests in Parent ADSs to which such holder is entitled pursuant to Section 2.02(e) and (B) any dividends or other distributions to which such holder is entitled pursuant to Section 2.02(c), and the Certificate so surrendered shall forthwith be cancelled. In the event of a transfer of ownership of Company Shares that is not registered in the transfer records of the Company, certificates representing, in the aggregate, the proper number of Parent ADSs and a check in the amount equal to any cash in lieu of any fractional interest in Parent ADSs to which such holder is entitled pursuant to Section 2.02(e) and any dividends or other distributions to which such holder is entitled pursuant to Section 2.02(c) may be issued to a transferee if the Certificate representing such Company Shares is presented to the Exchange Agent, properly endorsed and otherwise in proper form for transfer, accompanied by all documents required to evidence and effect such transfer and by evidence that any applicable stock transfer taxes have been paid. Until surrendered as contemplated by this Section 2.02, each Certificate shall be deemed at all times after the Effective Time to represent only the right to receive upon such surrender the Parent ADSs, cash in lieu of any fractional interest in Parent ADSs to which such holder is entitled pursuant to Section 2.02(e) and any dividends or other distributions to which such holder is entitled pursuant to Section 2.02(c).

(c) Distributions with Respect to Unexchanged Shares. No dividends or other distributions declared or made after the Effective Time with respect to the Parent Ordinary Shares with a record date after the Effective Time shall be paid to the holder of any unsurrendered Certificate with respect to the Parent ADSs represented thereby, and no cash payment in lieu of any fractional interest in Parent ADSs shall be paid to any such holder pursuant to Section 2.02(e), until the holder of such Certificate shall surrender such Certificate. Subject to the effect of escheat, tax or other applicable Laws (as defined in Section 3.05(a)), following surrender of any such Certificate, there shall be paid to the holder of whole Parent ADSs issued in exchange therefor, without interest, (i) promptly, the amount of any cash payable with respect to a fractional interest in Parent ADSs to which such holder is entitled pursuant to Section 2.02(e) and the amount of dividends or other distributions with a record date after the Effective Time and theretofore paid with respect to such whole Parent ADSs, and (ii) at the appropriate payment date, the amount of dividends or other distributions, with a record date after the Effective Time but prior to surrender and a payment date occurring after surrender, payable with respect to such whole Parent ADSs.

(d) No Further Rights in Company Shares. All Parent ADSs issued upon conversion of the Company Shares in accordance with the terms hereof (including any cash paid pursuant to Section 2.02(c) or (e)) shall be deemed to have been issued in full satisfaction of all rights pertaining to such Company Shares.

(e) No Fractional ADSs. (i) No certificates or scrip representing fractional interests in Parent ADSs shall be issued upon the surrender for exchange of Certificates, and such fractional interests will not entitle the owner thereof to vote or to any other rights of a shareholder of Parent or a holder of Parent ADRs or Parent ADSs.

(ii) As promptly as practicable following the Effective Time, the Exchange Agent shall determine the excess of (A) the number of whole Parent Ordinary Shares delivered to the Depositary by Parent pursuant to Section 2.02(a)(ii) over (B) the aggregate number of whole Parent Ordinary Shares represented by the Parent ADSs to be distributed to holders of Company Shares pursuant to Section 2.02(b) (such excess, as issued as Parent ADSs by the Depositary to the Exchange Agent, the “Excess ADSs”). As soon after the Effective Time as practicable, the Exchange Agent, as agent for the holders of Company Shares, who, but for the provisions of the Section 2.03(e), would be entitled to fractional interests in Parent ADSs, shall sell the Excess ADSs on the Nasdaq National Market (“Nasdaq”), all in the manner provided in clause (iii) of this Section 2.02(e).

(iii) The sale of the Excess ADSs by the Exchange Agent shall be executed on Nasdaq through one or more member firms of the National Association of Securities Dealers, Inc. (the “NASD”). Until the gross proceeds of

such sale or sales have been distributed to the holders of Company Shares who are entitled to receive such proceeds, the Exchange Agent will hold such proceeds in trust for the holders of Company Shares (the “Company Shares Trust”). Parent shall pay all commissions, transfer taxes and other out-of-pocket transaction costs, including the expenses and compensation of the Exchange Agent incurred in connection with such sale of the Excess ADSs. The Exchange Agent shall determine the portion of the Company Shares Trust to which each holder of Company Shares shall be entitled, if any, by multiplying the amount of the aggregate gross proceeds comprising the Company Shares Trust by a fraction, the numerator of which is the amount of the fractional share interest to which such holder of Company Shares is entitled and the denominator of which is the aggregate amount of fractional share interests to which all holders of Company Shares are entitled.

(iv) As soon as practicable after the determination of the amount of cash, if any, to be paid to the holders of Company Shares in lieu of any fractional interest in Parent ADSs and subject to Section 2.02(i), the Exchange Agent shall make available such amounts to such holders of Company Shares.

(f) Adjustments to Exchange Ratio. The Exchange Ratio shall be adjusted to reflect appropriately the effect of any stock split, reverse stock split, stock dividend (including any dividend or distribution of securities convertible into Parent Ordinary Shares, Parent ADSs or Company Class A Common Stock), extraordinary cash dividends, reorganization, recapitalization, reclassification, combination, exchange of shares or other like change with respect to Parent ADSs, Parent Ordinary Shares or Company Class A Common Stock occurring on or after the date hereof and prior to the Effective Time.

(g) Termination of Exchanges. Any Parent ADSs issuable or deliverable in respect of Certificates pursuant to this Article II and any cash in lieu of fractional interests in Parent ADSs payable pursuant to Section 2.02(e), plus any cash dividends or other distributions that such holder has the right to receive pursuant to Section 2.02(c), that remains unclaimed by any holders of Certificates six months after the Effective Time shall be held by or on behalf of the Depositary, subject to the instruction of Parent, in an account or accounts in Singapore designated for such purpose and on behalf of such holders of Certificates. Any cash remaining unclaimed by holders of Certificates or Company Shares three years after the Effective Time (or such earlier date immediately prior to such time as such cash would otherwise escheat to or become property of any Governmental Authority or as is otherwise provided by applicable Law) shall, to the extent permitted by applicable Law, become the property of the Surviving Corporation or Parent, as Parent may determine, free and clear of any claims or interest of any person previously entitled thereto.

(h) No Liability. None of the Exchange Agent, Parent or the Surviving Corporation shall be liable to any holder of Company Shares for any such Company Shares (or dividends or distributions with respect thereto), or cash delivered to a public official pursuant to any abandoned property, escheat or similar Law.

(i) Withholding Rights. Each of the Surviving Corporation and Parent shall be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of Company Shares such amounts as it is required to deduct and withhold with respect to the making of such payment under the Code, or any provision of state, local or foreign tax Law. To the extent that amounts are so deducted or withheld by the Surviving Corporation or Parent, as the case may be, such withheld amounts shall be treated for all purposes of this Agreement as having been paid to the holder of the Company Shares in respect of which such deduction and withholding was made by the Surviving Corporation or Parent, as the case may be.

(j) Lost Certificates. If any Certificate shall have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and, if required by the Surviving Corporation, the posting by such person of a bond, in such reasonable amount as the Surviving Corporation may direct, as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will issue in exchange for such lost, stolen or destroyed Certificate the Parent ADSs, any cash in lieu of fractional interests in Parent ADSs to which the holders thereof are entitled pursuant to Section 2.02(e) and any dividends or other distributions to which the holders thereof are entitled pursuant to Section 2.02(c).

SECTION 2.03. Stock Transfer Books. At the Effective Time, the stock transfer books of the Company shall be closed and there shall be no further registration of transfers of Company Shares thereafter on the records of the Company. From and after the Effective Time, the holders of Certificates representing Company Shares outstanding immediately prior to the Effective Time shall cease to have any rights with respect to such Company Shares, except as otherwise provided in this Agreement or by Law. On or after the Effective Time, any Certificates presented to the Exchange Agent or Parent for any reason shall be converted into Parent Ordinary Shares or Parent ADSs, any cash in lieu of fractional interests in Parent Ordinary Shares or Parent ADSs to which the holders thereof are entitled pursuant to Section 2.02(e) and any dividends or other distributions to which the holders thereof are entitled pursuant to Section 2.02(c).

SECTION 2.04. Company Stock Options. (a) At the Effective Time, Parent shall issue Substitute Options (as defined below) in accordance with this Section 2.04 to all holders of options to purchase shares of Company Class A Common Stock (the “Company Stock Options”) outstanding, whether or not exercisable and whether or not vested, immediately prior to the Effective Time under the Company 1999 Stock Purchase and Option Plan and the Company 2000 Equity Incentive Plan (collectively, the “Company Stock Option Plans”). Parent shall issue the Substitute Options under the terms of the new stock option plans to be adopted by Parent at the Parent Shareholders’ Meeting (the “New Stock Option Plans”) to replace each of the Company Stock Option Plans. The terms and conditions of the New Stock Option Plans shall be substantially similar in all material respects with the terms and conditions of each of the Company Stock Option Plans, provided that the New Stock Option Plans shall differ from the terms and conditions of the Company Stock Option Plans to the extent necessary to comply with Singapore Law. The Company shall use reasonable efforts to take all necessary action, including obtaining the consent of any holder of Company Stock Options, to implement the substitution of the Company Stock Options with Substitute Options pursuant to the terms of the New Stock Option Plans and in accordance with this Section 2.04; provided, however, that any Company Stock Option that is not substituted with a Substitute Option because the Company Stock Option holder rejects the Substitute Option shall terminate as of the Effective Time. At the Effective Time, (a) each Company Stock Option shall be substituted by Parent with Substitute Options in such manner that Parent (A) is a corporation “issuing a stock option in a transaction to which Section 424(a) applies” within the meaning of Section 424 of the Code and the regulations thereunder or (B), to the extent that Section 424 of the Code does not apply to any such Company Stock Option, would be such a corporation were Section 424 of the Code to apply to such Company Stock Option, and (b) each Substitute Option shall entitle its holder to acquire, on substantially the same terms and conditions as were applicable to the Company Stock Option for which the Substitute Option was substituted, (A) a number of Parent Ordinary Shares equal to the product (rounded down to the nearest whole Parent Ordinary Share) of (1) the number of shares of Company Class A Common Stock that were issuable upon exercise of the related Company Stock Option immediately prior to the Effective Time multiplied by (2) the Option Exchange Ratio (which shall be the number equal to the product of the Exchange Ratio multiplied by 10), and (B) the per share exercise price of each Substitute Option shall be equal to the quotient (rounded up to the nearest cent) arrived at by dividing (1) the per share exercise price of each related Company Stock Option by (2) the Option Exchange Ratio (each, a “Substitute Option”); provided, however, that, upon exercise of a Substitute Option, the holder thereof shall have the right to elect to receive Parent ADSs rather than Parent Ordinary Shares and, upon such election, the holder shall receive a number of Parent ADSs equal to the number of Parent Ordinary Shares subject to the Substitute Option divided by ten (rounded down to the nearest whole Parent ADS).

(b) Subject to the approval of the shareholders of Parent, Parent shall take all corporate action necessary to make available for issuance a sufficient number of Parent Ordinary Shares to be issued upon exercise of the Substitute Options granted in accordance with this Section 2.04.

(c) As soon as practicable after the Effective Time, Parent shall deliver, or cause to be delivered, to each holder of a Substitute Option an appropriate notice setting forth such holder’s rights pursuant thereto. Parent shall ensure, to the extent required by, and subject to the provisions of, the Company Stock Option Plans, that Company Stock Options that qualified as incentive stock options under Section 422 of the Code prior to the Effective Time shall be substituted by Substitute Options that qualify as incentive stock options under Section

422 of the Code after the Effective Time. As soon as practicable after the Effective Time, the Parent Ordinary Shares subject to Substitute Options shall be covered by an effective registration statement on Form S-8 and Form F-6 (or any successor form) or another appropriate form, and Parent shall use its reasonable best efforts to maintain the effectiveness of such registration statement or registration statements for so long as Substitute Options remain outstanding. In addition, Parent shall use reasonable best efforts to cause the Parent Ordinary Shares subject to the Substitute Options or underlying any Parent ADSs to be issued upon exercise of the Substitute Options to be listed on the Singapore Exchange Securities Trading Limited (the “SGX-ST”), and to cause any Parent ADSs to be issued upon exercise of the Substitute Options to be quoted on Nasdaq.

(d) On or after the date of this Agreement and prior to the Effective Time, each of Parent and the Company shall take all necessary action such that, with respect to each member of the Company Board and each employee of the Company that is subject to Section 16 of the Exchange Act, the acquisition by such person of Parent Ordinary Shares, Parent ADSs or Substitute Options in the Merger and the disposition by any such person of Parent Ordinary Shares, Parent ADSs or Company Stock Options pursuant to the transactions contemplated by this Agreement shall be exempt from the short-swing profit liability rules of Section 16(b) of the Exchange Act pursuant to Rule 16b-3 promulgated thereunder.

SECTION 2.05. Employee Stock Purchase Plan. With respect to the Company’s Employee Stock Purchase Plan (the “Purchase Plan”), the purchase period currently in progress shall be shortened by setting a new purchase date in accordance with paragraph 2 of Section 18 of the Purchase Plan (the “New Purchase Date”). The Purchase Plan shall terminate immediately following the purchase of shares of Company Class A Common Stock on the New Purchase Date.

SECTION 2.06. No Appraisal Rights. In accordance with Section 262 of the DGCL, no appraisal rights shall be available to holders of Company Class A Common Stock in connection with the Merger.

Except as set forth in the Company Disclosure Schedule that has been prepared by the Company and delivered by the Company to Parent in connection with the execution and delivery of this Agreement (the “Company Disclosure Schedule”) (which Company Disclosure Schedule shall be arranged in sections corresponding to the sections of this Article III, and any information disclosed in any such section of the Company Disclosure Schedule shall be deemed to be disclosed only for purposes of the corresponding section of this Article III, unless it is reasonably apparent that the disclosure contained in such section of the Company Disclosure Schedule applies to other representations and warranties contained in this Article III), the Company hereby represents and warrants to Parent that:

SECTION 3.01. Corporate Organization. (a) Each of the Company and each subsidiary of the Company (each a “Company Subsidiary”) is a corporation or other organization duly organized, validly existing and, where applicable, in good standing under the laws of the jurisdiction of its incorporation or organization and has the requisite corporate power and authority and all necessary governmental approvals to own, lease and operate its properties and to carry on its business as it is now being conducted, except where the failure to be so organized, existing or in good standing or to have such power, authority and governmental approvals could not reasonably be expected, individually or in the aggregate, to prevent or materially delay consummation of the Merger or any of the transactions contemplated by this Agreement or the Voting Agreements (collectively, the “Transactions”) or otherwise prevent or materially delay the Company from performing its obligations under this Agreement and could not reasonably be expected, individually or in the aggregate, to have a Company Material Adverse Effect (as defined in Section 9.03(a)). The Company and each Company Subsidiary is duly qualified or licensed to do business, and, where applicable, is in good standing, in each jurisdiction where the character of the properties

owned, leased or operated by it or the nature of its business makes such qualification or licensing necessary, except where the failure to be so qualified or licensed and in good standing could not reasonably be expected, individually or in the aggregate, to prevent or materially delay consummation of any of the Transactions or otherwise prevent or materially delay the Company from performing its obligations under this Agreement and could not reasonably be expected, individually or in the aggregate, to have a Company Material Adverse Effect.

(b) A true and complete list of all the Company Subsidiaries, together with the jurisdiction of incorporation or organization of each Company Subsidiary and the percentage of the outstanding capital stock of each Company Subsidiary owned by the Company and each other Company Subsidiary, is set forth in Section 3.01(b) of the Company Disclosure Schedule. Except as set forth in Section 3.01(b) of the Company Disclosure Schedule, the Company does not directly or indirectly own any equity or similar interest in, or any interest convertible into or exchangeable or exercisable for any equity or similar interest in, any corporation, partnership, joint venture or other business association or entity.

SECTION 3.02. Certificate of Incorporation and By-laws. The Company has made available to Parent or its counsel a complete and correct copy of the Certificate of Incorporation and the By-laws or equivalent organizational documents, each as amended to date, of the Company and each Company Subsidiary. Such Certificates of Incorporation, By-laws or equivalent organizational documents are in full force and effect. Neither the Company nor any Company Subsidiary is in violation of any of the provisions of its Certificate of Incorporation, By-laws or equivalent organizational documents, except where such violations could not reasonably be expected, individually or in the aggregate, to prevent or materially delay consummation of any of the Transactions or otherwise prevent or materially delay the Company from performing its obligations under this Agreement and could not reasonably be expected, individually or in the aggregate, to have a Company Material Adverse Effect.

The execution and delivery of this Agreement by the Company and the consummation by the Company of the Transactions have been duly and validly authorized by all necessary corporate action on the part of the Company, and no other corporate proceedings on the part of the Company are necessary to authorize this Agreement or to consummate the Transactions (other than, with respect to the Merger, the approval and adoption of this Agreement by the holders of a majority of the then-outstanding shares of Company Class A Common Stock, if and to the extent required by applicable law, and the filing and recordation of appropriate merger documents as required by the DGCL).

(c) Except as set forth in this Section 6.04(c), the Company Board shall not make a change in the Company Board Recommendation (a “Change in the Company Board Recommendation”) in a manner adverse to Parent or Merger Sub or approve or recommend, or cause or permit the Company to enter into any letter of intent, agreement or obligation with respect to, any Competing Transaction. Notwithstanding the foregoing, if, prior to the approval of this Agreement and the Merger at the Company Stockholders’ Meeting, the Company Board determines, in its good faith judgment prior to the Effective Time and after consultation with independent legal counsel (who may be the Company’s regularly engaged independent legal counsel), that it is required to make a Change in the Company Board Recommendation to comply with its fiduciary obligations to the Company and its stockholders under applicable Law, the Company Board may recommend a Superior Proposal, but only (i) after providing written notice to Parent (a “Notice of Company Superior Proposal”) advising Parent that the Company Board has received a Superior Proposal, specifying the material terms and conditions of such Superior Proposal and identifying the person making such Superior Proposal and indicating that the Company Board intends to effect a Change in the Company Board Recommendation and the manner in which it intends (or may intend) to do so, and (ii) if Parent does not, within 48 hours of Parent’s receipt of the Notice of Company Superior Proposal, deliver to the Company a binding, written offer that the Company Board determines, in its good faith judgment (after having consulted with independent legal counsel and a financial advisor of internationally recognized reputation) to be at least as favorable to the Company’s stockholders as such Superior Proposal. Any disclosure that the Company Board may be compelled to make with respect to the receipt of a proposal or offer for a Competing Transaction under applicable Law or Rule 14d-9 or 14e-2 or that the Company Board determines to comply with its fiduciary duties to the Company and its stockholders will not constitute a violation of this Agreement, provided that such disclosure states that no action will be taken by the Company Board in violation of this Section 6.04(c). The obligation of the Company to call, give notice of, convene and hold the Company Stockholders’ Meeting shall not be limited or otherwise affected by the commencement, disclosure, announcement or submission to it of any Competing Transaction, or by any Change in the Company Board Recommendation, except in the event that this Agreement is terminated in accordance with Section 8.01(j). The Company shall not submit to the vote of its stockholders any Competing Transaction, or propose to do so, except in the event that this Agreement is terminated in accordance with Section 8.01(j).

Notwithstanding the foregoing, if, prior to the approval of the Share Issuance, the Parent Name Change, the New Stock Option Plans Adoption and the Parent Board Appointments at the Parent Shareholders’ Meeting, the Parent Board determines, in its good faith judgment prior to the Effective Time and after consultation with independent legal counsel (who may be Parent’s regularly engaged independent legal counsel), that to make a Change in the Parent Board Recommendation is required to comply with its fiduciary obligations to Parent and its shareholders under applicable Law, the Parent Board may recommend a Superior Proposal, but only (i) after providing written notice to the Company (a “Notice of Parent Superior Proposal”) advising the Company that the Parent Board has received a Superior Proposal, specifying the material terms and conditions of such Superior Proposal and identifying the person making such Superior Proposal and indicating that the Parent Board intends to effect a Change in the Parent Board Recommendation and the manner in which it intends (or may intend) to do so, and (ii) if the Company does not, within 48 hours of the Company’s receipt of the Notice of Parent Superior Proposal, deliver to Parent a binding written offer that the Parent Board determines, in its good faith judgment (after having consulted with independent legal counsel and a financial advisor of internationally recognized reputation) to be at least as favorable to Parent’s shareholders as such Superior Proposal. Any disclosure that the Parent Board may be compelled to make with respect to the receipt of a proposal or offer for a Competing Transaction under applicable Law (including, without limitation, the

Singapore Code on Take-overs and Mergers) or Rule 14d-9 or 14e-2 or the requirements of the Securities Industry Counsel or that the Parent Board determines to comply with its fiduciary duties to Parent and its shareholders will not constitute a violation of this Agreement, provided that such disclosure states that no action will be taken by the Parent Board in violation of this Section 6.04(d). The obligation of Parent to call, give notice of, convene and hold the Parent Shareholders’ Meeting shall not be limited or otherwise affected by the commencement, disclosure, announcement or submission to it of any Competing Transaction, or by any Change in the Parent Board Recommendation, except in the event that this Agreement is terminated in accordance with Section 8.01(k).

(e) A “Competing Transaction” means with respect to the Company or Parent, as the case may be, any of the following (other than the Transactions): (i) a transaction, whether a merger, purchase of assets, tender offer or otherwise, which, if consummated, would result in a third party’s acquiring (A) more than 20% of the equity securities of the Company or of Parent, as the case may be, (B) all or substantially all of the assets of the Company and the Company Subsidiaries, taken as a whole, or of Parent and the Parent Subsidiaries, taken as a whole, or (C) is conditioned upon the non-consummation of the Transactions; (ii) in the case of the Company, any solicitation in opposition to approval and adoption of this Agreement by the Company’s stockholders; and (iii) in the case of Parent, any solicitation in opposition to approval of the Share Issuance, Parent Name Change, the New Stock Option Plans Adoption or the Parent Board Appointments by Parent’s shareholders.

(f) A “Superior Proposal” means with respect to the Company or Parent, as the case may be, an unsolicited bona fide offer made by a third party which (i) is for a transaction, whether a merger, purchase of assets, tender offer or otherwise, other than the Transactions, which, if consummated, would result in (A) the stockholders of such party immediately preceding such transaction holding less than 50% of the equity interest in the surviving or resulting entity of such transaction or (B) a third party’s acquiring all or substantially all of the assets of the Company and the Company Subsidiaries, taken as a whole, or Parent and the Parent Subsidiaries, taken as a whole, as the case may be, and (ii) is on terms that the Board of Directors of such party determines, in its good faith judgment (after having consulted with independent legal counsel and a financial advisor of internationally recognized reputation), taking into account, among other things, all legal, financial, regulatory and other aspects of the proposal and the person making the proposal, (A) if consummated pursuant to its terms, is reasonably likely to result in a transaction that is more favorable to the stockholders of such party (in their capacities as stockholders), from a financial point of view, than the Merger and (B) is reasonably capable of being completed on the terms proposed.

SECTION 6.05. Employee Benefits Matters. (a) For one year following the Effective Time, or such longer period as may be required by applicable Law or contract, Parent shall or shall cause the Surviving Corporation to provide or cause to be provided to employees of the Surviving Corporation or any other affiliate of Parent who were employees of the Company or any Company Subsidiary immediately prior to the Effective Time and, in each case, to the extent an employee continues employment with the Surviving Corporation or any other affiliate of Parent (the “Continuing Employees”) compensation and employee benefit plans, programs and policies and fringe benefits (other than equity based compensation arrangements) that, in the aggregate, are substantially similar to those that were provided to the Continuing Employees by the Company or any Company Subsidiary immediately prior to the execution of this Agreement.

Each such employee benefit plan, program or arrangement that provides health benefits to Continuing Employees shall waive pre-existing condition limitations with respect to the Continuing Employees to the same extent waived under the applicable group health plan of

the Company or any Company Subsidiary maintained prior to the Effective Time, and each Continuing Employee shall be given credit for amounts paid under the corresponding group health plan of the Company or any Company Subsidiary during the plan year in which the Effective Time occurs for purposes of applying deductibles, co-payments and out-of-pocket maximums for such plan year.

(c) As of the Effective Time, Parent shall cause the Surviving Corporation to honor for the one-year period following the Effective Time all employment and severance agreements existing as of the date hereof and set forth in Schedule 3.10(a) of the Company Disclosure Schedule between the Company or any Company Subsidiary and any current or former director, officer or employee of the Company or any Company Subsidiary.

SECTION 6.06. Directors’ and Officers’ Indemnification and Insurance. (a) The Certificate of Incorporation and By-laws of the Surviving Corporation shall contain provisions no less favorable with respect to indemnification than are set forth in Article Eight of the Certificate of Incorporation or Article V of the By-laws of the Company, which provisions shall not be amended, repealed or otherwise modified for a period of six years from the Effective Time in any manner that would affect adversely the rights thereunder of individuals who, at or prior to the Effective Time, were directors, officers, employees, fiduciaries or agents of the Company, unless such modification shall be required by law.

(b) The Surviving Corporation shall use its reasonable best efforts to maintain in effect, for six years from the Effective Time, the current directors’ and officers’ liability insurance policies maintained by the Company (provided that the Surviving Corporation may substitute therefor policies of at least the same coverage containing terms and conditions that are no less advantageous) with respect to matters occurring prior to the Effective Time; provided, however, that in no event shall the Surviving Corporation be required to expend pursuant to this Section 6.06(b) more than an amount per year equal to 200% of current annual premiums paid by the Company for such insurance (which premiums the Company represents and warrants to be $842,575 in the aggregate), it being understood that, if the premium required to be paid by Parent for such policy would exceed such 200% amount, then the coverage of such policy shall be reduced to the maximum amount that may be obtained for a per annum premium in such 200% amount.

(c) In the event the Company or the Surviving Corporation or any of their respective successors or assigns (i) consolidates with or merges into any other person and shall not be the continuing or surviving corporation or entity of such consolidation or merger or (ii) transfers all or substantially all of its properties and assets to any person, then, and in each such case, proper provision shall be made so that the successors and assigns of the Company or the Surviving Corporation, as the case may be, or at Parent’s option, Parent, shall assume the obligations set forth in this Section 6.06.

SECTION 6.07. Notification of Certain Matters. The Company shall give prompt notice to Parent, and Parent shall give prompt notice to the Company, of (a) the occurrence, or non-occurrence, of any event the occurrence, or non-occurrence, of which could reasonably be expected to cause any representation or warranty of such party contained in this Agreement to be untrue or inaccurate in any material respect and (b) any failure of the Company, Parent or Merger Sub, as the case may be, to comply with or satisfy any covenant or agreement to be complied with or satisfied by it hereunder, in the case of (a) or (b), such that the conditions under Section

7.02(a) or Section 7.02(b), in the case of the Company, or under Section 7.03(a) or Section 7.03(b), in the case of Parent, would not be satisfied; provided, however, that the delivery of any notice pursuant to this Section 6.07 shall not limit or otherwise affect the remedies available hereunder to the party receiving such notice.

SECTION 6.08. Company Affiliates. No later than 30 days after the date of this Agreement, the Company shall deliver to Parent a list of names and addresses of those persons who were, in the Company’s reasonable judgment, on such date, affiliates (within the meaning of Rule 145 of the rules and regulations promulgated under the Securities Act (each such person being a “Company Affiliate”)) of the Company. The Company shall provide Parent with such information and documents that the Company has in its possession as Parent shall reasonably request for purposes of reviewing such list.

In case, at any time after the Effective Time, any further action is necessary or desirable to carry out the purposes of this Agreement, the proper officers and directors of each party to this Agreement shall use their reasonable best efforts to take all such action.

SECTION 6.10. Plan of Reorganization. (a) This Agreement is intended to constitute a “plan of reorganization” within the meaning of Section 1.368-2(g) of the income tax regulations promulgated under the Code. From and after the date of this Agreement and until the Effective Time, each party hereto shall use its reasonable best efforts to cause the Merger to qualify, and will not knowingly take any action, cause any action to be taken, fail to take any action or cause any action to fail to be taken which action or failure to act could reasonably be expected to prevent the Merger from qualifying, as a reorganization within the meaning of Section 368(a) of the Code (including the receipt and continued effectiveness of the Private Letter Ruling) or the exchange by Eligible Company Stockholders of Company Shares for Parent ADSs pursuant to the Merger from satisfying the requirements of Section 1.367(a)-3(c) of the Regulations other than subsection (3)(C) thereof. Following the Effective Time, neither the Surviving Corporation, Parent nor any of their affiliates shall knowingly take any action, cause any action to be taken, fail to take any action or cause any action to fail to be taken, which action or failure to act could reasonably be expected to cause the Merger to fail to qualify as a reorganization within the meaning of Section 368(a) of the Code (including the failure to receive and maintain the continued effectiveness of the Private Letter Ruling) or the exchange by Eligible Company Stockholders of Company Shares for Parent ADSs pursuant to the Merger from satisfying the requirements of Section 1.367(a)-3(c) of the Regulations other than subsection (3)(C) thereof.

(b) As of the date hereof, the Company, after consultation with counsel, does not know of any reason (i) why it would not be able to deliver to counsel to the Company and Parent, at the date of the legal opinions referred to below, certificates, with customary exceptions and modifications thereto, to enable such firms to deliver legal opinions that (assuming receipt of the Private Letter Ruling) the Merger qualifies as a reorganization within the meaning of Section 368(a) of the Code, and the Company hereby agrees to use its reasonable best

efforts to deliver such certificates effective as of the date of such opinions or (ii) why counsel to the Company and Parent would not be able to deliver legal opinions that (assuming receipt of the Private Letter Ruling) the Merger qualifies as a reorganization within the meaning of Section 368(a) of the Code.

(c) As of the date hereof, Parent, after consultation with counsel, does not know of any reason (i) why it and Merger Sub would not be able to deliver to counsel to the Company and Parent, at the date of the legal opinions referred to below, certificates, with customary exceptions and modifications thereto, to enable such firms to deliver legal opinions that (assuming receipt of the Private Letter Ruling) the Merger qualifies as a reorganization within the meaning of Section 368(a) of the Code, and Parent hereby agrees to use its reasonable best efforts to deliver such certificates on behalf of both Parent and Merger Sub effective as of the date of such opinions, or (ii) why counsel to the Company and Parent would not be able to deliver legal opinions that (assuming receipt of the Private Letter Ruling) the Merger qualifies as a reorganization within the meaning of Section 368(a) of the Code.

(d) Parent and the Company shall cooperate and use their respective reasonable best efforts to obtain a private letter ruling from the IRS with respect to the transactions contemplated by this Agreement, as provided for under Section 1.367(a)-3(c)(9) of the Regulations, to qualify for an exception to the general rule under Section 367(a)(1) of the Code (the “Private Letter Ruling”). Such reasonable best efforts shall include, without limitation, Parent and Company’s making (or causing their respective affiliates to make) such representations or covenants as the IRS may reasonably request in connection with the Private Letter Ruling. Any written or substantive oral communications with the IRS to the extent possible shall be conducted jointly by the Company and Parent or Kirkland & Ellis LLP and Shearman & Sterling LLP, respectively. If the IRS does not issue the Private Letter Ruling, but there has been a change in law, clear guidance from the IRS or a change in facts that would nevertheless indicate that the opinion described below could be given, Parent and the Company shall use their reasonable best efforts each to obtain an opinion of a nationally recognized law firm that for federal income tax purposes the exchange by Eligible Company Stockholders of Company Shares solely for Parent ADSs pursuant to the Merger will not result in the recognition of gain under the provisions of Section 367(a) of the Code (a “Section 367 Opinion”). Parent and the Company agree to timely satisfy, or cause to be timely satisfied, all applicable tax reporting and filing requirements contained in the Code and the United States Income Tax Regulations with respect to the transactions contemplated hereby, including, without limitation, the reporting requirements contained in Section 1.367(a)-3(c)(6) of the Regulations.

(a) Parent shall promptly prepare and submit to the SGX-ST a listing application covering the Parent Ordinary Shares underlying the Parent ADSs to be issued in the Merger, pursuant to the Substitute Options and upon conversion of the Company Convertible Subordinated Notes, and shall use its reasonable best efforts to obtain, prior to the Effective Time, approval for such listing on the SGX-ST, subject to official notice of issuance to the SGX-ST and customary conditions, and the Company shall cooperate with Parent with respect to such listing.

(b) Parent shall promptly prepare and submit to the Nasdaq a listing application covering the Parent ADSs to be issued in the Merger, pursuant to Substitute Options and upon conversion of the Company Convertible Subordinated Notes, and shall use its reasonable best efforts to obtain, prior to the Effective Time, approval for the quotation of such Parent ADSs, subject to official notice of issuance to Nasdaq, and the Company shall cooperate with Parent with respect to such quotation.

SECTION 6.13. Public Announcements. The initial press release relating to this Agreement shall be a joint press release the text of which has been agreed to by each of Parent and the Company. Thereafter, unless otherwise required by applicable Law or the requirements of the SGX-ST or Nasdaq, no statement or other disclosure regarding the Transactions will be made by any party to this Agreement without the prior approval of

the Company and Parent, which approval shall not be unreasonably withheld or delayed, provided, however, that nothing in this Section 6.13 shall be deemed to limit the rights of the Company or Parent under Section 6.04.

SECTION 6.14. Board of Directors; Corporate Headquarters; Corporate Name. (a) Parent shall use its reasonable best efforts to, subject to the fiduciary duties of the Parent Board, (i) not increase the number of directors who are nominees of Singapore Technologies Semiconductors Pte Ltd prior to the Effective Time and cause the number of directors comprising the Parent Board as of immediately after the Effective Time to be 11, (ii) cause four of the current members of the Parent Board to resign effective as of immediately after the Effective Time, (iii) cause each of Mr. Robert Conn, Mr. Douglas Norby, Mr. Chong Sup Park and Mr. Dennis McKenna (the “Company Designated Directors”), assuming that each such person is willing to serve as a director, to be nominated for election as a director of Parent, effective as of the Effective Time, at the Parent Shareholders’ Meeting, (iv) cause Mr. Dennis McKenna to be appointed as Vice Chairman of the Parent Board as of the Effective Time, to serve as Vice Chairman and director until December 31, 2004, (v) cause one of Mr. Robert Conn, Mr. Douglas Norby or Mr. Chong Sup Park to be appointed to the Audit Committee of the Parent Board as of the Effective Time, and (vi) cause the Audit Committee Terms of Reference to be amended as of the Effective Time to provide, in accordance with NASD Rule 4350(h), that Parent shall conduct an appropriate review of all “related party transactions” (defined as transactions required to be disclosed pursuant to Rule 404 of Regulation S-K under the Securities Act or any successor provision thereto) for potential conflict of interest situations and that all such transactions must be approved by the Audit Committee of the Parent Board. If any Company Designated Director shall, prior to the Effective Time, die or determine not to serve as a director of Parent, the Company shall have the right to appoint another person who would qualify as an “independent” director under the rules of Nasdaq to become a Company Designated Director, subject to the approval of such person by the Parent Board (which approval shall not be unreasonably withheld).

(b) The corporate headquarters of Parent following completion of the Merger will remain in Singapore.

By:		/s/ DENNIS MCKENNA
Name:		Dennis McKenna
Title:		Chairman, Chief Executive Officer and President

I have been advised that as of the date of this letter I may be deemed to be, but do not admit that I am, an “affiliate” of CHIPPAC, INC., (the “Company”), as the term “affiliate” is defined for purposes of paragraphs (c) and (d) of Rule 145 of the rules and regulations (the “Rules and Regulations”) of the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Act”). Pursuant to the terms of the Agreement and Plan of Merger and Reorganization, dated as of February 10, 2004 (the “Merger Agreement”), among ST ASSEMBLY TEST SERVICES LTD, a Singapore public company limited by shares (“Parent”), CAMELOT MERGER, INC., a Delaware corporation (“Merger Sub”), and the Company, Merger Sub will be merged with and into the Company (the “Merger”). Capitalized terms used in this letter agreement without definition shall have the meanings assigned to them in the Merger Agreement.

As a result of the Merger, I may receive American Depositary Shares of Parent (“Parent ADSs”) each representing the right to receive ten ordinary shares, par value $0.25 per share, of Parent (“Parent Ordinary Shares”). I would receive such Parent ADSs in exchange for shares (or upon exercise of options for shares) owned by me of Class A common stock, par value $0.01 per share, of the Company (the “Company Shares”).

1. I represent, warrant and covenant to Parent that in the event I receive any Parent ADSs as a result of the Merger:

A. I shall not make any sale, transfer or other disposition of the Parent ADSs in violation of the Act or the Rules and Regulations.

B. I have carefully read this letter and the Merger Agreement and discussed the requirements of such documents and other applicable limitations upon my ability to sell, transfer or otherwise dispose of the Parent ADSs, to the extent I felt necessary, with my own counsel. I have not relied upon Kirkland & Ellis LLP, counsel for the Company, or Shearman & Sterling LLP, counsel to Parent, in connection with my decision to execute this letter or otherwise in connection with any other agreement or document that I have entered into in connection with the Merger Agreement or the Transactions.

C. I have been advised that the issuance of the Parent ADSs to me pursuant to the Merger has been registered with the Commission under the Act on a Registration Statement on Form F-4. However, I have also been advised that, because at the time the Merger is submitted for a vote of the stockholders of the Company, (a) I may be deemed to be an affiliate of the Company and (b) the distribution by me of the Parent ADSs has not been registered under the Act, I may not sell, transfer or otherwise dispose of the Parent ADSs issued to me in the Merger unless (i) such sale, transfer or other disposition is made in conformity with the volume and other limitations of Rule 145 promulgated by the Commission under the Act, (ii) such sale, transfer or other disposition has been registered under the Act, (iii) in the opinion of counsel reasonably acceptable to Parent or (iv) in accordance with a “no-action” letter obtained by me from the staff of the Commission, such sale, transfer or other disposition is otherwise exempt from registration under the Act.

D. I understand that Parent is under no obligation to register the sale, transfer or other disposition of the Parent ADSs by me or on my behalf under the Act or, except as provided in paragraph 2(A) below, to take any other action necessary in order to make compliance with an exemption from such registration available.

E. I understand that there will be placed on the American Depositary Receipts evidencing the Parent ADSs issued to me, or any substitutions therefor, a legend stating in substance:

THE SHARES REPRESENTED BY THIS CERTIFICATE WERE ISSUED IN A TRANSACTION TO WHICH RULE 145 PROMULGATED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, APPLIES. THE SHARES REPRESENTED BY THIS CERTIFICATE MAY ONLY BE TRANSFERRED PURSUANT TO A REGISTRATION STATEMENT OR IN ACCORDANCE WITH AN EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT OF 1933, AS AMENDED, INCLUDING RULE 145.

F. I understand that unless I certify to Parent that a sale or transfer is made in conformity with the provisions of Rule 145, or pursuant to a registration statement, Parent reserves the right to put the following legend on the certificates issued to my transferee:

THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 AND WERE ACQUIRED FROM A PERSON WHO RECEIVED SUCH SHARES IN A TRANSACTION TO WHICH RULE 145 PROMULGATED UNDER THE SECURITIES ACT OF 1933 APPLIES. THE SHARES HAVE BEEN ACQUIRED BY THE HOLDER NOT WITH A VIEW TO, OR FOR RESALE IN CONNECTION WITH, ANY DISTRIBUTION THEREOF WITHIN THE MEANING OF THE SECURITIES ACT OF 1933 AND MAY NOT BE SOLD, PLEDGED OR OTHERWISE TRANSFERRED EXCEPT PURSUANT TO A REGISTRATION STATEMENT OR IN ACCORDANCE WITH AN EXEMPTION FROM THE REGISTRATION REQUIREMENTS OF THE SECURITIES ACT OF 1933.

G. Execution of this letter should not be considered an admission on my part that I am an “affiliate” of the Company as described in the first paragraph of this letter, nor as a waiver of any rights I may have to object to any claim that I am such an affiliate on or after the date of this letter.

2. By Parent’s acceptance of this letter, Parent hereby agrees with me as follows:

A. For so long as Parent is obligated to file reports pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the undersigned continues to own Parent ADSs received in the Merger, Parent shall (a) use its reasonable best efforts to (i) file, on a timely basis, all reports and data required to be filed with the Commission by it pursuant to Section 13 of the Exchange Act, and (ii) furnish to me upon request a written statement as to whether Parent has complied with such reporting requirements during the 12 months preceding any proposed sale of the Parent ADSs by me under Rule 145, and (b) otherwise use its reasonable efforts to permit such sales pursuant to Rule 145 and Rule 144. Parent hereby represents to me that it has filed all reports required to be filed with the Commission under Section 13 of the Exchange Act during the 12 months preceding the date of this letter.

B. It is understood and agreed that certificates with the legends set forth in paragraphs I(E) and l(F) above will be substituted by delivery of certificates without such legends if (i) one year shall have elapsed from the date the undersigned acquired the Parent ADSs received in the Merger and the provisions of Rule 145(d)(2) are then available to the undersigned, (ii) two years shall have elapsed from the date the undersigned acquired the Parent ADSs received in the Merger and the provisions of Rule 145(d)(3) are then applicable to the undersigned, or (iii) Parent has received either an opinion of counsel, which opinion and counsel shall be reasonably satisfactory to Parent, or a “no action” letter obtained by the undersigned from the staff of the Commission, to the effect that the restrictions imposed by Rule 145 under the Act no longer apply to the undersigned.

Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in a mutually acceptable manner in order that the transactions contemplated by this Agreement be consummated as originally contemplated to the fullest extent possible.

VOTING AGREEMENT, dated as of February 10, 2004 (this “Agreement”), among ST ASSEMBLY TEST SERVICES LTD, a Singapore public company limited by shares (“Parent”), and the stockholders (each a “Stockholder”) of ChipPAC, Inc., a Delaware corporation (the “Company”), identified on the signature pages hereto.

WHEREAS, as of the date hereof, the Stockholders are the record and beneficial owner of the number of Shares (as defined below) set forth opposite each Stockholder’s name in Exhibit A hereto (the “Existing Shares” and, together with any shares of Company Class A Common Stock acquired by Stockholders after the date hereof, whether upon the exercise of warrants, options, conversion of convertible securities, or by means of purchase, dividend, distribution, split-up, recapitalization, combination, exchange of shares, gift, bequest, inheritance or as a successor in interest in any capacity or otherwise, and any shares into which or for which any or all of the Existing Shares and additional shares may be changed or exchanged, the “Shares”); and

WHEREAS, as an inducement and a condition to entering into the Merger Agreement and incurring the obligations set forth therein, Parent has required that the Stockholders agree to enter into this Agreement.

NOW, THEREFORE, in consideration of the foregoing and the mutual covenants and agreements contained herein, and intending to be legally bound hereby, the parties hereto hereby agree as follows:

SECTION 1.01. Voting Agreement. (a) Each Stockholder hereby agrees that, from and after the date hereof and until the earlier to occur of the events set forth in Section 4.01, at every meeting of the stockholders of the Company, however called, and at every adjournment thereof, and in every action by consent of the stockholders of the Company, such Stockholder shall, provided that such Stockholder has not received notice from Parent (which notice may be delivered at any such meeting) stating Parent’s intention to exercise the Proxy at such meeting, appear at any such meeting or otherwise cause the Shares to be counted as present thereat for purposes of establishing a quorum, and shall vote or consent (or cause to be voted or consented) such Stockholder’s Shares: (i) in favor of the approval and adoption of the Merger Agreement, the Merger and the other Transactions and otherwise in such manner as may be necessary to consummate the Merger; and (ii) except as otherwise agreed to in writing in advance by Parent, against any action, proposal, agreement or transaction, including, but not limited to, any Competing Transaction (other than the Merger Agreement and the Merger), the purpose or effect of which would be to prevent, delay, postpone or materially adversely affect the Merger. In all other matters, the Shares shall be voted by and in a manner determined by such Stockholder.

(b) If a Stockholder fails for any reason to vote such Stockholder’s Shares as required by Section 1.01(a), the holder of the Proxy (as defined below) shall have the right to vote such Stockholder’s Shares at any meeting of the Company’s stockholders and in any action by written consent of the Company’s stockholders in accordance with Section 1.01(a) and the Proxy. The vote of a holder of the Proxy shall control in any conflict between a vote of such Stockholder’s Shares by a holder of the Proxy and a vote of such Stockholder’s Shares by such Stockholder with respect to the matters set forth in Section 1.01(a).

(c) Each Stockholder hereby agrees that such Stockholder shall not enter into any agreement or understanding with any person the effect of which would be inconsistent with or violative of any provision contained in Section 1.01(a), 1.01(b) or 1.02.

(d) This Agreement shall only apply to actions taken by the undersigned in such Stockholder’s capacity as a Stockholder and no provision of this Agreement shall limit or otherwise restrict any Stockholder with respect to any act or omission that such Stockholder may undertake or authorize in such Stockholder’s capacity as a director or officer of the Company, including, without limitation, any vote by the Stockholder in such Stockholder’s capacity as a director or officer of the Company with respect to any matter presented to the Company Board.

SECTION 1.02. Irrevocable Proxy. Concurrently with the execution of this Agreement, each Stockholder has delivered to Parent a proxy in the form attached as Exhibit B hereto (the “Proxy”), which such Stockholder agrees shall be irrevocable to the fullest extent permissible by Law, with respect to the Shares.

SECTION 2.01. Organization, Qualification. (a) Such Stockholder, if it is an individual, has all legal capacity to enter into this Agreement and to deliver the Proxy and to carry out his or her obligations hereunder.

(b) Such Stockholder, if it is a corporation or other legal entity, is duly organized, validly existing and, if applicable, in good standing under the Laws of the jurisdiction of its incorporation or formation and has the requisite power and authority and all necessary governmental approvals to execute and deliver this Agreement and perform its obligations under this Agreement.

SECTION 2.02. Authority Relative to this Agreement. Such Stockholder has all necessary power and authority to execute and deliver this Agreement and the Proxy and to perform such Stockholder’s obligations hereunder. This Agreement and the Proxy have been duly and validly executed and delivered by such Stockholder and, assuming due execution and delivery of this Agreement by Parent, constitute legal, valid and binding obligations of such Stockholder, enforceable against such Stockholder in accordance with their terms.

SECTION 2.03. No Conflict. (a) The execution and delivery of this Agreement and the Proxy by such Stockholder do not, and the performance of this Agreement and the Proxy by such Stockholder shall not, (i) conflict with or violate the certificate of incorporation or by-laws or equivalent organizational documents of such Stockholder (if such Stockholder is a corporation or other legal entity), (ii) assuming satisfaction of the requirements set forth in Section 2.03(b) below, conflict with or violate the terms of any trust agreements or equivalent organizational documents of such Stockholder (if such Stockholder is a trust), (iii) conflict with or violate any Law applicable to such Stockholder or by which the Shares owned by such Stockholder are bound or affected or (iv) result in any breach of, or constitute a default (or an event that with notice or lapse of time or both would become a default) under, or give to others any rights of termination, amendment, acceleration or cancellation of, or result in the creation of a lien or encumbrance on any of the Shares owned by such Stockholder pursuant to, any note, bond, mortgage, indenture, contract, agreement, lease, license, permit, franchise or other instrument or obligation to which such Stockholder is a party or by which such Stockholder or the Shares owned by such Stockholder are bound or affected, except for any such conflicts, violations, breaches, defaults or other occurrences that would not, individually or in the aggregate, prevent or materially delay such Stockholder from performing its obligations under this Agreement and the Proxy.

(b) The execution and delivery of this Agreement and the Proxy by such Stockholder does not, and the performance of this Agreement and the Proxy by such Stockholder shall not, require any consent, approval, authorization or permit of any Governmental Authority on the part of such Stockholder.

SECTION 2.04. Title to Company Securities. (a) As of the date hereof, such Stockholder is the record and beneficial owner of the number of Shares and the outstanding principal amount of the 2.50% Convertible Notes and the 8% Convertible Notes (the “Company Convertible Subordinated Notes”, and together with the Shares, the “Company Securities”), in each case, as set forth opposite such Stockholder’s name on Exhibit A hereto. Except as set forth on Exhibit A, such Company Securities are, now and, at all times during the term hereof will be, all the securities of the Company owned either of record or beneficially, by such Stockholder. The Company Securities owned by such Stockholder are now and, at all times during the term hereof will be, owned free and clear of all Liens, other than any Liens created by this Agreement. Except as provided in this Agreement, such Stockholder has not appointed or granted any proxy, which appointment or grant is still effective, with respect to the Shares owned by such Stockholder.

(b) To the knowledge of such Stockholder, no person controlled by such Stockholder (excluding any other Stockholder) is the record or beneficial owner of 2% or more of the outstanding Company Securities.

SECTION 2.05. Information Provided. (a) To the knowledge of such Stockholder, after due inquiry, none of the information relating to such Stockholder specifically provided by or on behalf of such Stockholder for inclusion in the Registration Statement will, at the time the Proxy Statement is filed with the SEC or sent or given to stockholders of the Company, contain any untrue statement of material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading in any material respect.

(b) To the knowledge of such Stockholder, after due inquiry, none of the information relating to such Stockholder specifically provided by or on behalf of such Stockholder for inclusion in the Parent Shareholders Circular will, at the time the Parent Shareholders Circular is filed with the SGX-ST or sent or given to shareholders of Parent, contain any untrue statement of material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein, in light of the circumstances under which they were made, not misleading in any material respect.

SECTION 3.01. No Disposition or Encumbrance of Company Securities. Each Stockholder hereby agrees that during the term of this Agreement, except as contemplated by this Agreement and the Merger Agreement, such Stockholder shall not (a) sell, transfer, tender, assign, pledge, encumber, contribute to the capital of any entity, hypothecate, give or otherwise dispose of, grant a proxy or power of attorney with respect to, deposit into any voting trust or enter into a voting arrangement or agreement, or create or permit to exist any Liens of any nature whatsoever with respect to, any of such Stockholder’s Company Securities (or agree or consent to, or offer to do, any of the foregoing), (b) take any action that would have the effect of preventing or adversely affecting such Stockholder from performing such Stockholder’s obligations hereunder or (c) directly or indirectly, initiate, solicit or encourage any person to take actions that could reasonably be expected to lead to the occurrence of any of the foregoing. Notwithstanding anything to the contrary contained herein, any Stockholder and/or one or more of such Stockholder’s affiliates shall be allowed to sell, transfer, assign or otherwise dispose of any of such Stockholder’s Company Securities to the extent such disposition or dispositions would prevent such Stockholder from being a “five percent transferee shareholder” as defined in Section 1.367(a)-3(c)(5)(ii) of the Regulations as of the Effective Time (a “5% Shareholder”). In determining the amount of Company Securities permitted to be disposed: (y) such Stockholder may make reasonable factual assumptions and apply a reasonable interpretation

of U.S. tax law based on the advice of counsel; and (z) the relevant U.S. income tax provisions should be applied by substituting “4.9 percent” for “five percent” in Section 1.367(a)-3(c)(5)(ii) of the Regulations. Parent hereby agrees to provide any relevant data as may be reasonably requested by such Stockholder for the purpose of determining whether such Stockholder or any affiliate would be a 5% Shareholder.

SECTION 3.02. No Solicitation of Transactions. Each Stockholder agrees that, between the date of this Agreement and the date of termination of the Merger Agreement in accordance with its terms, such Stockholder shall not, and shall not permit any of its subsidiaries or any of its or its subsidiaries’ directors, officers or employees to, and shall use its best efforts to cause the investment bankers, attorneys, accountants and other representatives retained by it or any of its subsidiaries not to, directly or indirectly: (i) solicit, initiate or knowingly encourage (including by way of furnishing nonpublic information), or take any other action knowingly to facilitate, any inquiries or the making of any proposal or offer that constitutes a Competing Transaction; (ii) enter into or maintain or continue discussions or negotiations with any person or entity in furtherance of such inquiries or to obtain a Competing Transaction; (iii) agree to, approve, endorse or recommend any Competing Transaction or enter into any letter of intent or other contract, agreement or commitment contemplating or otherwise relating to any Competing Transaction; or (iv) authorize or permit any of the officers, directors or employees of such Stockholder or any of its subsidiaries, or any investment banker, financial advisor, attorney, accountant or other representative retained by such Stockholder, to take any such action. Each Stockholder shall notify Parent as promptly as practicable (and in any event within two days after any senior executive of such Stockholder attains knowledge thereof; provided, however, that if such senior executive is a director of the Company, the notice to Parent required by this Section 3.02 shall be provided within one day after such senior executive attains knowledge thereof) if any proposal or offer, or any inquiry or contact with any person with respect thereto, regarding a Competing Transaction is made, specifying the material terms and conditions thereof and the identity of the party making such proposal or offer or inquiry or contact. Each Stockholder immediately shall cease and cause to be terminated all existing discussions or negotiations with any parties conducted heretofore with respect to a Competing Transaction. Nothing in this Section 3.02 shall prevent any Stockholder from acting in such Stockholder’s capacity as an officer or director of the Company, or taking any action in such capacity (including at the direction of the Company Board).

SECTION 3.04. Additional Shares. Each Stockholder agrees, while this Agreement is in effect, to give a prompt written notice to Parent of the number of any new Shares acquired by such Stockholder after the date hereof.

SECTION 3.05. Disclosure. Each Stockholder hereby agrees to permit Parent and the Company to publish and disclose in the Registration Statement, the Proxy Statement and the Parent Shareholders Circular (including all documents and schedules filed with the SEC or the SGX-ST), and in any press release or other disclosure document in which Parent and the Company reasonably determine in their good faith judgment that such disclosure is required by Law, including the rules and regulations of the SEC, or is appropriate, in connection with the Merger and the other Transactions, such Stockholder’s identity and ownership of the Company Class A Common Stock and the nature of such Stockholder’s commitments, arrangements and understandings under this Agreement, subject to Parent or the Company using its reasonable best efforts to consult with the Stockholder and to give the Stockholder the right to review and comment on any such disclosure.

SECTION 3.06. Public Announcement. Each Stockholder agrees to not make any public announcement in opposition to, or in competition with, the Merger Agreement or the consummation of the Merger.

SECTION 3.07. Limitations on Sale of Parent Ordinary Shares. (a) From the date of this Agreement until 90 days after the date of the Effective Time, each Stockholder agrees not to sell, transfer, tender, assign, pledge, encumber, contribute to the capital of any entity, hypothecate, give or otherwise dispose of, or enter into any put, call, forward purchase contract or forward sale contract or any other contract, agreement or arrangement having the effect of decreasing or eliminating the risk of ownership with respect to, any Parent Ordinary Shares or Parent ADSs (or agree or consent to, or offer to do, any of the foregoing); provided, however, that (i) each Stockholder may transfer Parent Ordinary Shares or Parent ADSs to an affiliate of such Stockholder if such affiliate agrees in writing to comply with the provisions of this Section 3.07; (ii) each Stockholder may sell, during any three-month period, such number of Parent Ordinary Shares (whether in the form of Parent Ordinary Shares or Parent ADSs) equal to the maximum number of Parent Ordinary Shares that such Stockholder would be permitted to sell during such three-month period in accordance with Rule 144(e) under the Securities Act, assuming that the Parent Ordinary Shares were quoted on Nasdaq and that such rule applied to all sales by the Stockholder and regardless of whether such rule applies; (iii) each Stockholder may transfer Parent Ordinary Shares or Parent ADSs to any transferee in a transaction consummated in accordance with any private placement exemption from the registration requirements of the Securities Act if such transferee agrees in writing to comply with the provisions of this Section 3.07; and (iv) each Stockholder listed on Exhibit C hereto may transfer Parent Ordinary Shares or Parent ADSs to such Stockholder’s limited partners, owners or equity holders provided that such transfer complies with the provisions of Rule 145 of the Securities Act.

(b) Each Stockholder acknowledges and agrees that there will be placed on the Parent ADRs evidencing the Parent ADSs issued in the Merger to such Stockholder, or any substitutions thereof (including, without limitation, any Parent Ordinary Shares issued in exchange for such Parent ADSs), a legend stating in substance:

THE SHARES REPRESENTED BY THIS CERTIFICATE WERE ISSUED IN A TRANSACTION TO WHICH RULE 145 PROMULGATED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, APPLIED. THE SHARES REPRESENTED BY THIS CERTIFICATE MAY ONLY BE TRANSFERRED IN ACCORDANCE WITH THE TERMS OF AN AGREEMENT, DATED FEBRUARY 10, 2004, AMONG PARENT, THE REGISTERED HOLDER HEREOF AND THE OTHER PARTIES IDENTIFIED ON THE SIGNATURE PAGE THERETO, A COPY OF WHICH IS ON FILE AT THE PRINCIPAL OFFICES OF PARENT.

SECTION 3.08. Termination of Other Agreements.

Such Stockholder has not relied upon Kirkland & Ellis LLP, counsel for the Company, or Shearman & Sterling LLP, counsel to Parent, in connection with such Stockholder’s decision to execute this Agreement or otherwise in connection with any other document or agreement such Stockholder has entered into in connection with the Merger Agreement or the Transactions.

SECTION 4.01. Termination.

We understand that ChipPAC Inc. (“ChipPAC”), ST Assembly Test Services Ltd (“STATS”) and Camelot Merger, Inc. (“Merger Sub”), a wholly owned subsidiary of STATS, propose to enter into an Agreement and Plan of Merger and Reorganization substantially in the form of the draft dated 10 February 2004 (the “Merger Agreement”) which provides, among other things, for the merger (the “Merger”) of Merger Sub with and into ChipPAC. Pursuant to the Merger, ChipPAC will become a wholly owned subsidiary of STATS, and each outstanding share of class A common stock, par value $0.01 per share (the “ChipPAC Common Stock”) of ChipPAC, other than shares held in treasury, will be converted into the right to receive 0.87 shares (the “Exchange Ratio”) of American Depositary Shares (“ADS”), each ADS represents 10 ordinary shares of par value S$0.25 each in the capital of STATS (the “STATS ADS’”), subject to adjustment in certain circumstances. The terms and conditions of the Merger are more fully set forth in the Merger Agreement.

You have asked for our opinion as to whether the Exchange Ratio pursuant to the Merger Agreement is fair from a financial point of view to STATS.

We have assumed and relied upon without independent verification the accuracy and completeness of all information supplied or otherwise made available to us by ChipPAC and/or STATS for the purposes of this opinion. With respect to the financial forecasts, we have assumed that they have been reasonably prepared on bases reflecting the best currently available estimates and judgments of the future financial performance of ChipPAC and STATS. We have not made any independent valuation or appraisal of the assets or liabilities of ChipPAC or STATS, nor have we been furnished with any such appraisals. Morgan Stanley has relied upon, without independent verification, the assessment by the management of ChipPAC and STATS of their respective technology and products, and the integration of ChipPAC’s technology with STATS’s technology and the timing of introduction of future products incorporating such technology. We have relied upon, without independent verification, the assessment by the managements of STATS and ChipPAC of: (i) the strategic, financial and other benefits expected to result from the Merger; (ii) the timing and risks associated with the integration of STATS and ChipPAC; (iii) their ability to retain key employees of STATS and ChipPAC, respectively and (iv) the validity of, and risks associated with, STATS and ChipPAC’s existing and future technologies, intellectual property, products, services and business models.

We have assumed that in the course of obtaining the necessary approvals and consents required for the Merger, that no restrictions will be imposed that will have a material adverse effect on the contemplated benefits expected to be derived in the proposed Merger. In addition, we have assumed that the Merger will be consummated in accordance with the terms set forth in the Merger Agreement, including among other things, that the Merger will be treated as a tax-free reorganization pursuant to the Internal Revenue Code of 1986. Our opinion is necessarily based on financial, economic, market and other conditions as in effect on, and the information made available to us as of, the date hereof.

Please note that Morgan Stanley and its associated companies (the “Morgan Stanley Group”) are engaged in securities, asset management and credit transaction services businesses. Our securities business is engaged in securities underwriting, trading and brokerage activities, foreign exchange, commodities and derivatives trading as well as providing investment banking and financial advisory services. In the ordinary course of our underwriting, trading, brokerage, asset management, credit transaction services businesses and financing activities, any member of the Morgan Stanley Group may at any time hold long or short positions, and may trade or otherwise effect transactions, for its own account or the accounts of customers, in debt or equity securities or senior loans of any company that may be involved in the Merger.

We have acted as financial advisor to the Board of Directors of STATS in connection with the Merger and will receive a fee for our services. In the past, Morgan Stanley Asia (Singapore) Pte and its affiliates have provided financial advisory and financing services for STATS and have received fees for the rendering of these services.

It is understood that this letter is for the benefit of and use of the Board of Directors of STATS and may not be used or disclosed for any other purpose without our prior written consent except that this opinion may be included in any filing made by STATS in respect of the transaction with the Securities and Exchange Commission to the extent required by law or regulatory requirement.

We express no opinion whatever and make no recommendation at all as to ChipPAC’s and STATS’s underlying decision to effect the Merger or as to how the holders of ChipPAC Common Stock or ordinary shareholders or ADS holders of STATS should vote at their respective meetings held in connection with the Merger. We do not express and should not be deemed to have expressed any views on any other terms of the Merger. We also express no opinion and accordingly accept no responsibility for or as to the prices at which ChipPAC Common Stock or ordinary shares or ADSs of STATS will trade following announcement of the Merger or as to the financial performance of STATS following consummation of the Merger.

Based upon and subject to the foregoing, we are of the opinion on the date hereof, that the Exchange Ratio pursuant to the Merger Agreement is fair from a financial point of view to STATS.

You have asked us to advise you with respect to the fairness, from a financial point of view, of the Exchange Ratio (as defined below) to the holders of Class A common stock, par value $0.01 per share (“ChipPAC Common Stock”), of ChipPAC, Inc. (“ChipPAC”) provided for in an Agreement and Plan of Merger and Reorganization by and among ST Assembly Test Services Ltd (“STTS”), Camelot Merger, Inc., a wholly owned subsidiary of STTS (“Merger Sub”), and ChipPAC (the “Merger Agreement”). The Merger Agreement provides for, among other things, the merger of Merger Sub with and into ChipPAC (the “Merger”) pursuant to which each share of ChipPAC Common Stock issued and outstanding immediately prior to the effective time of the Merger will be converted into the right to receive 0.87 (the “Exchange Ratio”) American Depositary Shares of STTS (“STTS ADS”), with each STTS ADS representing the right to receive 10 ordinary shares, par value S$0.25 per share, of STTS (“STTS Ordinary Shares”).

In arriving at our opinion, we have reviewed a draft dated February 9, 2004 of the Merger Agreement as well as certain publicly available business and financial information relating to ChipPAC and STTS. We also have reviewed certain other information relating to ChipPAC and STTS, including financial forecasts, provided to or discussed with us by the managements of ChipPAC and STTS, and have met with the managements of ChipPAC and STTS to discuss the businesses and prospects of ChipPAC and STTS, respectively. We also have considered certain financial and stock market data of ChipPAC and STTS and have compared that data with similar data for other publicly held companies in businesses we deemed similar to those of ChipPAC and STTS, and we have considered, to the extent publicly available, the financial terms of certain business combinations and other transactions which have been effected. We also considered such other information, financial studies, analyses and investigations and financial, economic and market criteria which we deemed relevant.

In connection with our review, we have not assumed any responsibility for independent verification of any of the foregoing information and have relied on such information being complete and accurate in all material respects. With respect to financial forecasts relating to ChipPAC provided to or discussed with us by the management of ChipPAC, we have been advised, and we have assumed, that such forecasts have been reasonably prepared on bases reflecting the best currently available estimates and judgments of the management of ChipPAC as to the future financial performance of ChipPAC. As you are aware, STTS has not provided us with financial forecasts relating to STTS beyond calendar year 2004 and we therefore have relied, at your direction, upon the assessments of the management of ChipPAC as to such matters. We have been advised, and we have assumed, that the financial forecasts relating to STTS with respect to calendar year 2004 provided to or discussed with us by the management of STTS and the financial forecasts relating to STTS beyond calendar year 2004 provided to or discussed with us by the management of ChipPAC have been reasonably prepared on bases reflecting the best currently available estimates and judgments of the managements of STTS or ChipPAC, as the case may be, as to the future financial performance of STTS. In addition, we have relied, with your consent and without independent verification, upon the assessments of the managements of ChipPAC and STTS as to (i) the existing and future technology and products of ChipPAC and STTS and the risks associated with such technology and products, (ii) the ability of the managements of ChipPAC and STTS to integrate the businesses of ChipPAC and STTS and (iii) their ability to retain key employees and customers of ChipPAC and STTS. We also

have assumed, with your consent, that, in the course of obtaining any regulatory or third party consents, approvals or agreements in connection with the Merger, no limitations, restrictions or conditions will be imposed that would have an adverse effect on ChipPAC, STTS or the contemplated benefits of the Merger and that the Merger will be consummated as set forth in the Merger Agreement and other relevant documents without waiver, modification or amendment of any material term, condition or agreement thereof. Representatives of ChipPAC have advised us, and we therefore further have assumed, that the Merger Agreement, when executed, will conform to the draft reviewed by us in all respects material to our analyses. In addition, we have not been requested to make, and we have not made, an independent evaluation or appraisal of the assets or liabilities (contingent or otherwise) of ChipPAC or STTS, nor have we been furnished with any such evaluations or appraisals. Our opinion is necessarily based upon information made available to us as of the date hereof and financial, economic, market and other conditions as they exist and can be evaluated on the date hereof. We are not expressing any opinion as to the actual value of STTS ADSs when issued to the holders of ChipPAC Common Stock pursuant to the Merger or the prices at which STTS ADSs or STTS Ordinary Shares will trade at any time. In connection with our engagement, we were not requested to, and we did not, solicit third party indications of interest in acquiring all or any part of ChipPAC. Our opinion does not address the relative merits of the Merger as compared to other business strategies or transactions that might be available to ChipPAC, nor does it address the underlying business decision of ChipPAC to proceed with the Merger.

We have acted as financial advisor to ChipPAC in connection with the Merger and will receive a fee for our services, a significant portion of which is contingent upon the consummation of the Merger. We also will receive a fee for rendering this opinion. We and our affiliates in the past have provided and in the future may provide services to ChipPAC and STTS unrelated to the proposed Merger, for which services we and our affiliates have received, and would expect to receive, compensation. In the ordinary course of our business, we and our affiliates may actively trade securities of ChipPAC and STTS for our and such affiliates’ own accounts and for the accounts of customers and, accordingly, may at any time hold a long or short position in such securities.

It is understood that this letter is for the information of the Board of Directors of ChipPAC in connection with its evaluation of the Merger and does not constitute a recommendation to any stockholder as to how such stockholder should vote or act with respect to any matters relating to the Merger.

Based upon and subject to the foregoing, it is our opinion that, as of the date hereof, the Exchange Ratio is fair to the holders of ChipPAC Common Stock, from a financial point of view.

3. Grant of Substitute Options. A holder of an Option that is outstanding and unexercised immediately prior to the Effective Time shall be granted a Substitute Option subject to the terms and conditions set forth in this Section 3. Anything in the Plan to the contrary notwithstanding, the holder of a Substitute Option may elect to receive ADSs in lieu of Shares upon the exercise of a Substitute Option, and upon such election, the holder of the Substitute Option shall receive a number of ADSs equal to the quotient resulting from dividing the number of Shares subject to the Option for which a Substitute Option is exercisable, by the number 10 (rounded down to the nearest whole ADS). The per Share exercise price of a Substitute Option shall be equal to the quotient (rounded

up to the nearest cent) resulting from dividing the per ChipPAC Share exercise price of the Option substituted with the Substitute Option, by the Exchange Ratio; provided, however, that the per Share exercise price of a Substitute Option shall in no event be less than par value of a Share. The exercise period within which a Substitute Option is exercisable shall be the same exercise period applicable to the Option substituted with the Substitute Option; provided, however, that (i) the exercise period applicable to a Participant who was an employee of ChipPAC or any Subsidiary at the time of grant of an Option and a Substitute Option shall in no event be greater than 120 months, measured from the date of grant of the Option so substituted and (ii) that the exercise period applicable to a Participant who was not an employee of the Company or any Subsidiary at the time of grant of a Substitute Option shall in no event be greater than 60 months, measured from the date of grant of the Substitute Option.

Substitute Options granted under the Plan shall be subject to such terms and conditions and evidenced by agreements as shall be determined from time to time by the Committee to the extent not inconsistent with the provisions of the Plan.

5. Administration of the Plan.

In administering the Plan, the Committee shall provide the Participants with such financial statements as may be required pursuant to applicable law.

6. Limitation on the Aggregate Number of Shares. The number of Shares issued under the Plan (including the number of Shares with respect to which Substitute Options may be granted under the Plan (and which may be issued upon the exercise or payment thereof)) shall not exceed, in the aggregate, 7.2 million Shares, which is an aggregate number that is intended to be equal to or greater than the product of the aggregate number of ChipPAC Shares subject to all Options, multiplied by the Exchange Ratio (as such numbers are equitably adjusted pursuant to Section 9 hereof). If any Substitute Options expire unexercised or unpaid or are canceled, terminated or forfeited in any manner without the issuance of Shares or payment thereunder, the Shares with respect to which such Substitute Options were granted shall become available for issuance pursuant to options or other awards under the ESOP. In addition, Shares that are not made subject to Substitute Options hereunder shall become available for issuance pursuant to options or other awards under the ESOP. Shares to be issued upon exercise of a Substitute Option may be authorized, but unissued Shares, as the Committee shall determine.

7. Incentive Stock Options. All Incentive Stock Options shall comport with all requirements set forth in Section 422 of the Code. To the extent that the aggregate Fair Market Value of Shares with respect to which Substitute Options that are intended to be Incentive Stock Options are exercisable for the first time by any individual during any calendar year exceeds US$100,000 (measured as of the date the Options substituted with the Substitute Options were granted), such options shall be treated as options that are not Incentive Stock Options.

9. Adjustment for Change in Capitalization of the Company. In the event of a reorganization, recapitalization, stock split, stock dividend, combination of shares, merger, consolidation or other change in the Shares or ADSs, the Committee shall make appropriate changes in the number and type of shares authorized by the Plan, the number and type of shares covered by outstanding Substitute Options and the exercise prices thereof.

10. Taxes. The Company shall be entitled, if necessary or desirable, to withhold (or secure payment from the Participant in lieu of withholding) the amount of any withholding or other tax due from the Company with respect to any amount payable and/or Shares of ADSs issuable under the Plan, and the Company may defer such payment or issuance unless indemnified to its satisfaction.

11. Termination and Amendment. The Committee at any time may suspend or terminate the Plan and make such additions or amendments as it deems advisable under the Plan, except that the Committee shall obtain shareholder approval of any amendment to the Plan to the extent necessary and desirable to comply with applicable law; provided that, subject to Section 8 hereof, the Committee shall not change any of the terms of a written agreement with respect to an Option or Substitute Option between the Company and a Participant without the approval of the Participant. Unless terminated earlier in accordance with this Section 11, the Plan shall terminate on the earlier of the tenth anniversary of the date the Plan becomes effective and the date that each Substitute Option has been exercised.

12. Shareholder Approval. The Plan shall be subject to approval by the shareholders of the Company at the time that the transactions contemplated by the Merger Agreement are subject to shareholder approval. Such shareholder approval shall be obtained in the manner and to the degree required under applicable laws. The Plan shall not become effective and no Substitute Option shall be granted under the Plan in the event that the Plan is not approved by the shareholders of the Company, and in no event prior to the Effective Time.

13. Governing Law. The validity, construction, interpretation, administration and effect of the Plan shall be determined in accordance with the laws of the Republic of Singapore.

If a Substitute Option expires or becomes unexercisable without having been exercised in full, or is surrendered pursuant to an Option Exchange Program, the unpurchased Shares that were subject thereto shall become available for future grant or sale under the ESOP; provided, however, that Shares that have actually been issued under the Plan upon exercise of a Substitute Option shall not be returned to the Plan and shall not become available for future distribution under the Plan.

(i) Multiple Administrative Bodies. The Plan may be administered by different Committees with respect to different groups of Service Providers.

(ii) Other Administration. Other than as provided above, the Former Plan and this Plan shall be administered by (A) the Board or (B) a Committee, which committee shall be constituted to satisfy Applicable Laws.

(b) Powers of the Administrator. Subject to the provisions of the Plan, and in the case of a Committee, subject to the specific duties delegated by the Board to such Committee, the Administrator shall have the authority, in its discretion:

(i) to determine the Fair Market Value, in accordance with Section 2 (q) hereof;

(ii) to determine the number of Shares to be covered by each Substitute Option granted hereunder in accordance with the provisions of the Merger Agreement;

(iv) to determine the terms and conditions, not inconsistent with the terms of the Plan, of any Substitute Option granted hereunder;

(vi) to construe and interpret the terms of the Plan and awards granted pursuant to the Plan;

(vii) to prescribe, amend and rescind rules and regulations relating to the Plan, including rules and regulations relating to sub-plans established for the purpose of qualifying for preferred tax treatment under tax laws of jurisdictions other than in the United States;

(viii) to modify or amend each Substitute Option (subject to Section 14(c) of the Plan), including the discretionary authority to extend the post-termination exercisability period of Substitute Options longer than is otherwise provided for in the Plan;

(ix) to the extent permitted under Applicable Law, to allow Optionees to satisfy withholding tax obligations by electing to have the Company withhold from the Shares or ADSs to be issued upon exercise of a Substitute Option that number of Shares having a Fair Market Value equal to the amount required to be withheld. The Fair Market Value of the Shares to be withheld shall be determined on the date that the amount of tax to be withheld is to be determined. All elections by an Optionee to have Shares withheld for this purpose shall be made in such form and under such conditions as the Administrator may deem necessary or advisable;

(x) to authorize any person to execute on behalf of the Company any instrument required to effect the grant of a Substitute Option previously granted by the Administrator; and

(xi) to make all other determinations deemed necessary or advisable for administering the Plan.

(c) Effect of Administrator’s Decision. The Administrator’s decisions, determinations and interpretations shall be final, binding and conclusive on all Optionees and any other holders of Substitute Options.

5. Eligibility. Each holder of an Option shall be granted a Substitute Option in accordance with the terms and conditions of this Plan, including the terms set forth in the Substitute Option Notice.

(a) Each Option shall have been designated in the Option Agreement as either an Incentive Stock Option or a Nonstatutory Stock Option. However, notwithstanding such designation, to the extent that the aggregate Fair Market Value of the Shares with respect to which Incentive Stock Options are exercisable for the first time by the Optionee during any calendar year (under all plans of the Company and any Parent or Subsidiary) exceeds US$100,000, such Substitute Options shall be treated as Nonstatutory Stock Options. For purposes of this Section 6(a), Incentive Stock Options shall be taken into account in the order in which they were granted. The Fair Market Value of the Shares shall be determined as of the time the Option with respect to such Shares was granted.

(b) Neither the Plan nor any Substitute Option shall confer upon an Optionee any right with respect to continuing the Optionee’s relationship as a Service Provider with the Company, nor shall they interfere in any way with the Optionee’s right or the Company’s right to terminate such relationship at any time, with or without cause.

7. Term of Plan. Subject to Section 18 hereof, the Plan shall become effective upon approval by the shareholders of the Company of the Board adoption of the Plan. It shall continue in effect for a term of the shorter of ten (10) years and the period ending on the date that each Substitute Option has been exercised, unless terminated earlier under Section 14 hereof.

8. Term of Substitute Option. The term of a Substitute Option shall be the same term applicable to the Option substituted with the Substitute Option and that is stated in the Option Agreement, subject to the limitations in this Section 8. In the case of a Substitute Option substituted for an Option, which was granted as an Incentive Stock Option, the term of the Substitute Option shall be ten (10) years, measured from the date of grant of the Option so substituted or such shorter term as may be provided in the Option Agreement. In the case of a Substitute Option substituted for an Option, which was granted as an Incentive Stock Option, to an Optionee who at the time of the grant of the Option so substituted owned ChipPAC Shares representing more than ten percent (10%) of the total combined voting power of all classes of shares of ChipPAC or any Parent or Subsidiary of ChipPAC, the term of the Substitute Option shall be five (5) years, measured from the date of grant of the Option so substituted or such shorter term as may be provided in the Option Agreement. In the case of a Substitute Option granted to a person who was not an Employee at the time of the grant of the Substitute Option, the term of the Substitute Option shall be five (5) years, measured from the date of grant of the Substitute Option or such shorter term as may be provided in the Option Agreement.

(a) Substitute Option Exercise Price. The per Share exercise price of a Substitute Option shall be equal to the quotient (rounded up to the nearest cent) arrived at by dividing the per ChipPAC Share exercise price applicable to the Option substituted with the Substitute Option, by the Exchange Ratio; provided, however, that the per Share exercise price of a Substitute Option shall in no event be less than the par value of a Share.

(b) Exercise Dates. Subject to Section 8 hereof, the Substitute Option shall be exercisable at the same time and within the same periods applicable to the Option that was substituted with the Substitute Option.

(c) Form of Consideration. The acceptable form of consideration for exercising a Substitute Option, including the method of payment shall be the same form of consideration and method of payment applicable to the Option substituted with the Substitute Option. In the case of an Incentive Stock Option, the Administrator shall have determined the acceptable form of consideration at the time of grant. Such consideration may consist entirely of:

(iv) to the extent permitted under Applicable Law, other Shares which (A) in the case of Shares acquired upon exercise of a Substitute Option, have been owned by the Optionee for more than six months on the date of surrender, and (B) have a Fair Market Value on the date of surrender equal to the aggregate exercise price of the Shares as to which the Substitute Option shall be exercised;

(v) consideration received by the Company under a cashless exercise program implemented by the Company in connection with the Plan;

(vi) a reduction in the amount of any Company liability to the Optionee, including any liability attributable to the Optionee’s participation in any Company-sponsored deferred compensation program or arrangement;

(viii) such other consideration and method of payment for the issuance of Shares to the extent permitted by Applicable Laws.

(a) Procedure for Exercise; Rights as a Shareholder. (i) Each Substitute Option granted hereunder shall be exercisable according to the terms of the Plan and at such times and under such conditions applicable to the

Option substituted with the Substitute Option and set forth in the Option Agreement. Unless the Administrator provides otherwise, vesting of a Substitute Option granted hereunder shall be tolled during any unpaid leave of absence. A Substitute Option may not be exercised for a fraction of a Share.

(i) A Substitute Option shall be deemed exercised when the Company receives: (A) written or electronic notice of exercise (in accordance with the Option Agreement) from the person entitled to exercise the Substitute Option, and (B) full payment for the Shares with respect to which the Substitute Option is exercised. Full payment may consist of any consideration and method of payment authorized by the Administrator and permitted by the Option Agreement and the Plan.

(ii) Anything in this Plan to the contrary notwithstanding, the holder of a Substitute Option may elect to receive ADSs in lieu of Shares upon the exercise of the Substitute Option, and upon such election, the holder of the Substitute Option shall receive a number of ADSs equal to the quotient that results from dividing the number of Shares for which a Substitute Option is exercisable, by the number 10 (rounded down to the nearest whole ADS).

(iii) Shares or ADSs issued upon exercise of a Substitute Option shall be issued and held by or on behalf of the Optionee or, if requested by the Optionee, shall be issued and held by or on behalf of the Optionee and his or her spouse. Until the Shares or ADSs are issued (as evidenced by the appropriate entry on the books of the Company or of a duly authorized transfer agent of the Company), no right to vote or receive dividends or any other rights as a shareholder shall exist with respect to the Optioned Shares, notwithstanding the exercise of the Substitute Option. The Company shall issue (or cause to be issued) such Shares or ADSs promptly after the Substitute Option is exercised. No adjustment shall be made for a dividend or other right for which the record date is prior to the date the Shares or ADSs are issued, except as provided in Section 12 hereof.

(iv) Exercising a Substitute Option in any manner shall decrease the number of Shares thereafter available, both for purposes of the Plan and for sale under the Substitute Option, by the number of Shares as to which the Substitute Option is exercised.

(b) Termination of Relationship as a Service Provider. If an Optionee ceases to be a Service Provider, other than upon the Optionee’s death, Disability or retirement, the Optionee may exercise his or her Substitute Option within such period of time as is specified with respect to the Option substituted with the Substitute Option and set forth in the Notice of Grant to the extent that the Substitute Option is vested on the date of termination (but in no event later than the expiration of the term of such Substitute Option as set forth in the Option Agreement). In the absence of a specified time in the Option Agreement, the Substitute Option shall remain exercisable for 30 days following the Optionee’s termination (unless the Administrator determines a different length of time). If, on the date of termination, the Optionee is not vested as to his or her entire Substitute Option, the Shares covered by the unvested portion of the Substitute Option shall become available for issuance under the ESOP. If, after termination, the Optionee does not exercise his or her Substitute Option within the time specified by the Administrator, the Substitute Option shall terminate, and the Shares covered by such Substitute Option shall become available for issuance under the ESOP.

(c) Disability of Optionee. If an Optionee ceases to be a Service Provider as a result of the Optionee’s Disability, the Optionee may exercise his or her Substitute Option within such period of time as is specified with respect to the Option substituted with the Substitute Option and set forth in the Notice of Grant to the extent the Substitute Option is vested on the date of termination (but in no event later than the expiration of the term of such Substitute Option as set forth in the Option Agreement). In the absence of a specified time in the Option Agreement, the Substitute Option shall remain exercisable for six months following the Optionee’s termination (unless the Administrator determines a different length of time). If, on the date of termination, the Optionee is not vested as to his or her entire Substitute Option, the Shares covered by the unvested portion of the Substitute Option shall become available for issuance under the ESOP. If, after termination, the Optionee does not exercise his or her Substitute Option within the time specified herein, the Substitute Option shall terminate, and the Shares covered by such Substitute Option shall become available for issuance under the ESOP.

(d) Death of Optionee. If an Optionee dies while a Service Provider, the Substitute Option may be exercised within such period of time as is specified with respect to the Option substituted with the Substitute Option and set forth in the Notice of Grant (but in no event later than the expiration of the term of such Substitute Option as set forth in the Notice of Grant), by the Optionee’s estate or by a person who acquires the right to exercise the Substitute Option by bequest or inheritance, but only to the extent that the Substitute Option is vested on the date of death. In the absence of a specified time in the Option Agreement, the Substitute Option shall remain exercisable for six months following the Optionee’s termination (unless the Administrator determines a different length of time). If, at the time of death, the Optionee is not vested as to his or her entire Substitute Option, the Shares covered by the unvested portion of the Substitute Option shall become available for issuance under the ESOP. The Substitute Option may be exercised by the executor or administrator of the Optionee’s estate or, if none, by the person(s) entitled to exercise the Substitute Option under the Optionee’s will or the laws of descent or distribution. If the Substitute Option is not so exercised within the time specified herein, the Substitute Option shall terminate, and the Shares covered by such Substitute Option shall become available for issuance under the ESOP.

(e) Retirement of Optionee. If an Optionee ceases to be a Service Provider as a result of the Optionee’s voluntary retirement, the Optionee may exercise his or her Substitute Option within such period of time as is specified with respect to the Option that is substituted with the Substitute Option and set forth in the Notice of Grant to the extent the Substitute Option is vested on the date of retirement (but in no event later than the expiration of the term of such Substitute Option as set forth in the Option Agreement). In the absence of a specified time in the Option Agreement, the Substitute Option shall remain exercisable for 30 days following the Optionee’s retirement (unless the Administrator determines a different length of time). If, on the date of retirement, the Optionee is not vested as to his or her entire Substitute Option, the Shares covered by the unvested portion of the Substitute Option shall become available for issuance under the ESOP. If, after retirement, the Optionee does not exercise his or her Substitute Option within the time specified herein, the Substitute Option shall terminate, and the Shares covered by such Substitute Option shall become available for issuance under the ESOP. This Section 10(e) shall only apply to an Optionee who voluntarily retires from the Company or a Subsidiary on or after the date on which such Optionee has attained the age of 59¹/2. Notwithstanding anything in this Section 10(e) or an Option Agreement to the contrary, if the Administrator determines in the good faith exercise of its judgment that any Optionee who has retired engages in any conduct detrimental to the Company, upon such determination by the Administrator, such Substitute Option shall immediately and without further action on the part of the Company, expire and become unexercisable. No notice of such determination need be given to any Optionee in such circumstance.

(f) Change in Control. In the event of a Change in Control, only if provided in the Option Agreement with respect to the Options that was substituted with a Substitute Option, any Substitute Option awarded under this Plan to the extent not previously exercisable shall immediately become fully exercisable. The Administrator in its sole discretion may direct the Company to cash out all outstanding Substitute Options as of the date a Change in Control occurs or such other date as the Administrator may determine prior to the Change in Control.

(g) Buyout Provisions. The Administrator may at any time offer to buy out for a payment in cash or Shares, or, in the sole discretion of the Administrator, ADSs, a Substitute Option previously granted based on such terms and conditions as the Administrator shall establish and communicate to the Optionee at the time that such offer is made.

11. Non-Transferability of Substitute Options. Unless determined otherwise by the Administrator, a Substitute Option may not be sold, pledged, assigned, hypothecated, transferred, or disposed of in any manner other than by will or by the laws of descent or distribution and may be exercised, during the lifetime of the Optionee, only by the Optionee. If the Administrator makes a Substitute Option transferable to the extent permitted under Applicable Law, such Substitute Option shall contain such additional terms and conditions, as the Administrator deems appropriate.

12. Adjustments Upon Changes in Capitalization, Dissolution, Merger or Asset Sale.

(a) Changes in Capitalization. Subject to any required action by the shareholders of the Company, the number of Shares covered by each outstanding Substitute Option, and the number of Shares that have been authorized for issuance under the Plan but as to which no Substitute Options have yet been granted or that have been returned to the Plan upon cancellation or expiration of a Substitute Option, as well as the price per Share covered by each such outstanding Substitute Option, shall be proportionately adjusted for any increase or decrease in the number of issued Shares or ADSs resulting from a stock split, reverse stock split, stock dividend, combination or reclassification of the Shares or ADSs, or any other increase or decrease in the number of issued Shares or ADSs effected without receipt of consideration by the Company; provided, however, that conversion of any convertible securities of the Company shall not be deemed to have been “effected without receipt of consideration.” Such adjustment shall be made by the Board, whose determination in that respect shall be final, binding and conclusive. Except as expressly provided herein, no issuance by the Company of shares of any class, or securities convertible into shares of any class, shall affect, and no adjustment by reason thereof shall be made with respect to, the number or price of Shares subject to a Substitute Option.

(b) Dissolution or Liquidation. In the event of the proposed dissolution or liquidation of the Company, the Administrator shall notify each Optionee as soon as practicable prior to the effective date of such proposed transaction. The Administrator in its discretion may provide for an Optionee to have the right to exercise his or her Substitute Option until ten (10) days prior to such transaction as to all of the Optioned Shares covered thereby, including Shares as to which the Substitute Option would not otherwise be exercisable. In addition, the Administrator may provide that any Company repurchase option applicable to any Shares purchased upon exercise of a Substitute Option shall lapse as to all such Shares, provided the proposed dissolution or liquidation takes place at the time and in the manner contemplated. To the extent it has not been previously exercised, a Substitute Option shall terminate immediately prior to the consummation of such proposed action.

(c) Merger or Asset Sale. In the event of a merger of the Company with or into another corporation, or the sale of substantially all of the assets of the Company, each outstanding Substitute Option shall be assumed or an equivalent option or right substituted by the successor corporation or a Parent or Subsidiary of the successor corporation. In the event that the successor corporation refuses to assume or substitute for the Substitute Option, the Optionee shall fully vest in and have the right to exercise the Substitute Option as to all of the Optioned Shares, including Shares as to which it would not otherwise be vested or exercisable. If a Substitute Option becomes fully vested and exercisable in lieu of assumption or substitution in the event of a merger or sale of assets, the Administrator shall notify the Optionee in writing or electronically that the Substitute Option shall be fully vested and exercisable for a period of fifteen (15) days from the date of such notice, and the Substitute Option shall terminate upon the expiration of such period. For the purposes of this Section 12(c), the Substitute Option shall be considered assumed if, following the merger or sale of assets, the Substitute Option or right confers the right to purchase or receive, for each Share subject to the Substitute Option immediately prior to the merger or sale of assets, the consideration (whether stock, cash, or other securities or property) received in the merger or sale of assets by holders of Shares for each Share held on the effective date of the transaction (and if holders were offered a choice of consideration, the type of consideration chosen by the holders of a majority of the outstanding Shares); provided, however, that if such consideration received in the merger or sale of assets is not solely common stock or ordinary shares of the successor corporation or its Parent, the Administrator may, with the consent of the successor corporation, provide for the consideration to be received upon the exercise of the Substitute Option, for each Share subject to the Substitute Option, to be solely common stock or ordinary shares of the successor corporation or its Parent equal in fair market value to the per share consideration received by holders of Shares in the merger or sale of assets.

13. Date of Grant. The date of grant of an Option and the Substitute Option substituted therefor shall be, for all purposes except where noted otherwise, the date on which the administrator of the Former Plan made the

determination granting the Option, or such other later date as determined by the administrator of the Former Plan and set forth in the Option Agreement.

(a) Amendment and Termination. The Board may at any time amend, alter, suspend or terminate the Plan.

(b) Shareholder Approval. The Company shall obtain shareholder approval of any Plan amendment to the extent necessary and desirable to comply with Applicable Laws.

(c) Effect of Amendment or Termination. No amendment, alteration, suspension or termination of the Plan shall impair the rights of any Optionee, unless mutually agreed otherwise between the Optionee and the Administrator, which agreement must be in writing and signed by the Optionee and the Company. Termination of the Plan shall not affect the Administrator’s ability to exercise the powers granted to it hereunder with respect to Substitute Options granted under the Plan prior to the date of such termination.

(a) Legal Compliance. Shares shall not be issued pursuant to the exercise of a Substitute Option unless the exercise of such Substitute Option and the issuance and delivery of such Shares shall comply with Applicable Laws and shall be further subject to the approval of counsel for the Company with respect to such compliance.

(b) Investment Representations. As a condition to the exercise of a Substitute Option, the Company may require the person exercising such Substitute Option to represent and warrant at the time of any such exercise that the Shares are being purchased only for investment and without any present intention to sell or distribute such Shares if, in the opinion of counsel for the Company, such a representation is required.

16. Inability to Obtain Authority. The inability of the Company to obtain authority from any regulatory body having jurisdiction, which authority is deemed by the Company’s counsel to be necessary to the lawful issuance and sale of any Shares hereunder, shall relieve the Company of any liability in respect of the failure to issue or sell such Shares as to which such requisite authority shall not have been obtained.

17. Reservation of Shares. The Company, during the term of this Plan, shall at all times reserve and keep available such number of Shares as shall be sufficient to satisfy the requirements of the Plan.

18. Shareholder Approval. The adoption of the Plan shall be subject to approval by the shareholders of the Company at the time that the transactions contemplated by the Merger Agreement are subject to shareholder approval. Such shareholder approval shall be obtained in the manner and to the degree required under Applicable Laws. The Plan shall not become effective and no Substitute Option shall be granted under the Plan in the event that the Plan is not approved by the shareholders of the Company and in no event prior to the Effective Time.

19. Governing Law. The validity, construction, interpretation, administration and effect of the Plan shall be determined in accordance with laws of the Republic of Singapore.

Amended by ordinary resolution approved at the 6th Annual Meeting held on 8 June 2000

Amended by ordinary resolution approved at the 10th Annual General Meeting held on 25 April 2004

Amended by ordinary resolution approved at the Extraordinary Meeting held on 4 August 2004

The purpose of the Plan is to offer selected individuals an opportunity to acquire a proprietary interest in the success of the Company, or to increase such interest, by exercising Options to purchase Shares. Options granted under the Plan may include Nonstatutory Options as well as ISOs intended to qualify under Section 422 of the U.S. Tax Code.

The Board of Directors shall administer the Plan unless and until the Board of Directors delegates administration to a Committee, as provided herein. The Board of Directors may delegate administration of the Plan to one or more Committees consisting of two or more members of the Board of Directors. If administration is delegated to a Committee, the Committee shall have, in connection with the administration of the Plan, the powers theretofore possessed by the Board of Directors, including the power to delegate to a subcommittee any of the administrative powers the Committee is authorized to exercise, subject, however, to such resolutions, not inconsistent with the provisions of the Plan, as may be adopted from time to time by the Board of Directors. The Board of Directors may abolish the Committee at any time and revest in the Board of Directors the administration of the Plan. Any reference to the Board of Directors in the Plan shall be construed as a reference to the Committee (if any) to whom the Board of Directors has assigned a particular function.

At such time as the Company is subject to Section 162(m) of the U.S. Tax Code or an Optionee is subject to Section 16 of the U.S. Exchange Act, in the discretion of the Board of Directors, a Committee may consist solely

of two or more Outside Directors, in accordance with Section 162(m) of the U.S. Tax Code, and/or two or more Non-Employee Directors, in accordance with Rule 16b-3. Notwithstanding the foregoing, the Board of Directors or the Committee may (1) delegate to a committee of one or more members of the Board of Directors who are not Outside Directors the authority to grant Options to eligible persons who are either (a) not then Covered Employees and are not expected to be Covered Employees at the time of recognition of income resulting from such Option or (b) not persons with respect to whom the Company wishes to comply with Section 162(m) of the U.S. Tax Code and/or (2) delegate to a committee of one or more members of the Board of Directors who are not Non-Employee Directors the authority to grant Options to eligible persons who are not then subject to Section 16 of the U.S. Exchange Act.

Subject to the provisions of the Plan, the Board of Directors shall have full authority and discretion to take any actions it deems necessary or advisable for the administration of the Plan, including, without limitation, to (i) select Optionees from the individuals eligible to receive Options under the Plan; (ii) grant Options in accordance with the terms of the Plan; (iii) determine the terms and conditions of each Option; (iv) specify and approve the provisions of the Share Option Agreements, including, without limitation, the method of exercise and delivery of notice thereof, including via written or electronic media, in connection with their Options; (v) construe and interpret any Share Option Agreement delivered under the Plan; (vi) prescribe, amend and rescind rules and procedures relating to the Plan; (vii) employ such legal counsel, independent auditors and consultants as it deems desirable for the administration of the Plan and to rely upon any opinion received therefrom; (viii) vary the terms of Options to take account of tax, securities law and other regulatory requirements of foreign jurisdictions; (ix) make all legal and factual determinations; and (x) make all other determinations and take any other action desirable or necessary to interpret, construe or implement properly the provisions of the Plan or any Share Option Agreement.

All decisions, interpretations and other actions of the Board of Directors shall be final and binding on all Optionees and all persons deriving their rights from an Optionee.

Employees, Directors and Consultants shall be eligible for the grant of Options except as follows:

(i) Employees of Affiliated Companies, Directors who are not Employees and Consultants shall not be eligible for the grant of ISOs; and

(ii) Employees, Directors and Consultants, in each case, of Affiliated Companies who are residents of the United States shall not be eligible for the grant of Options.

An individual who owns more than 10% of the total combined voting power of all classes of outstanding shares of the Company, its Parent or any of its Subsidiaries shall not be eligible to be granted ISOs unless (i) the Exercise Price of the ISO is at least 110% of the Fair Market Value of a Share on the date of grant and (ii) such ISO by its terms is not exercisable after the expiration of five years from the date of grant. For purposes of this Subsection (b), in determining share ownership, the attribution rules of Section 424(d) of the U.S. Tax Code shall be applied.

Subject to the provisions of Section 7 relating to adjustment upon change in the Shares, no Employee shall be eligible to be granted an Option covering more than fifty million (50,000,000) Shares during any calendar

year. This Section 3(c) shall not apply at such times that the Company is not subject to Section 162(m) of the U.S. Tax Code or such other date required by Section 162(m) of the U.S. Tax Code and the rules and regulations promulgated thereunder.

Shares offered under the Plan may be authorized but unissued Shares. Subject to adjustment as provided pursuant to Section 7 hereof, the maximum aggregate number of Shares that may be issued under this Plan shall not exceed (i) 245 million Shares, plus (ii) any unissued Shares subject to any option or other awards or rights under the Existing Plans that expire unexercised or are otherwise cancelled as a result of a termination of those options or other awards or rights under the Existing Plans or the non-issuance of options or other awards or rights under the Existing Plans. The aggregate number of Shares that are subject to Options outstanding at any time under the Plan shall not exceed the number of Shares that then remain available for issuance. The Company, during the term of the Plan, shall at all times reserve and keep available sufficient Shares to satisfy the requirement of the Plan.

For purposes of determining the number of Shares that remain available for issuance under Section 4(a) hereof, the following Shares shall be added back to the Plan Limit and again be available for the purposes of the Plan and all other share incentive and option schemes approved by the Board of Directors and contracts of employment:

(i) The number of Shares tendered in accordance with applicable laws to pay the exercise price of an Option;

(ii) The number of Shares acquired by the Company under Section 6(b) below in satisfaction of any tax withholding requirement; and

(iii) The number of Shares subject to an Option that expire unexercised or that are cancelled or otherwise terminated.

Each grant of an Option under the Plan shall be evidenced by a Share Option Agreement between the Optionee and the Company. Such Option shall be subject to all applicable terms and conditions of the Plan and may be subject to any other terms and conditions which are not inconsistent with the Plan and which the Board of Directors deems appropriate for inclusion in a Share Option Agreement. The provisions of the various Share Option Agreements entered into under the Plan need not be identical.

Each Share Option Agreement shall specify the number of Shares that are subject to the Option and shall provide for the adjustment of such number in accordance with Section 7. The Share Option Agreement shall also specify whether the Option is an ISO or a Nonstatutory Option.

Each Share Option Agreement shall specify the Exercise Price. The Exercise Price of an ISO shall not be less than 100% of the Fair Market Value of a Share on the date of grant, and a higher percentage may be required by Section 3(b) hereof. In no event shall the Exercise Price of an Option be less than the par value of Share on the date of grant. Subject to the preceding two sentences, the Exercise Price under any Option shall be

determined by the Board of Directors at its sole discretion. The Exercise Price shall be payable in a form described in Section 6 hereof.

As a condition to the exercise of an Option, the Optionee shall make such arrangements as the Board of Directors may require for the satisfaction of any withholding tax obligations that may arise in connection with such exercise. The Board of Directors may require any Optionee to remit to the Company, prior to exercise of an Option, an amount sufficient to satisfy any applicable tax withholding requirements. The Board of Directors may permit such Optionee to satisfy, in whole or in part, such obligation to remit taxes by directing the Company to withhold Shares that would otherwise be received by such Optionee to satisfy the minimum statutory withholding rates for any applicable tax withholding purposes, in accordance with all applicable laws and pursuant to such rules as the Board of Directors may establish from time to time. The Company shall also have the right to deduct from all cash payments made to an Optionee (whether or not such payment is made in connection with the exercise of an Option) any applicable taxes required to be withheld with respect to such payments.

Each Share Option Agreement shall specify the date when all or any installment of the Option is to become exercisable. The exercisability provisions of any Share Option Agreement shall be determined by the Board of Directors at its sole discretion.

In the event of a Change of Control, in addition to any action required or authorized by the terms of a Share Option Agreement, the Board of Directors may, in its sole discretion unless otherwise provided in a Share Option Agreement, take any or all or any combination of the following actions as a result, or in anticipation, of any such event:

(i) accelerate the time period for purposes of vesting in, or realizing gain from, any outstanding Option made pursuant to this Plan;

(ii) provide for the continuation of any outstanding Options by the Company (if the Company is the survivor corporation);

(iii) provide for the assumption of outstanding Options by the surviving corporation or its parent;

(iv) provide for the substitution by the surviving corporation or its parent of options with substantially the same terms as outstanding Options;

(v) cancel each outstanding Option but only after payment to the Optionee of an amount in cash or cash equivalents equal to (A) the Fair Market Value of the Shares subject to such Option at the time of the merger or consolidation minus (B) the Exercise Price of the Shares subject to such Option; or

(vi) make adjustments or modifications to outstanding Options as the Board of Directors deems appropriate to maintain and protect the rights and interests of Optionees following the Change of Control.

Any such action approved by the Board of Directors shall be conclusive and binding on the Company and all Optionees.

Subject to this Section 5(g), the Share Option Agreement shall specify the term of the Option. The term of an Option granted to an Employee shall not exceed 10 years from the date of grant, and a shorter term may be required by Section 3(b) hereof. The term of an Option granted to a person who is not an Employee shall not exceed 5 years from the date of grant. Subject to the preceding two sentences, the Board of Directors at its sole discretion shall determine when an Option is to expire.

No Option shall be transferable by the Optionee other than to an Optionee’s personal representative on the death of that Optionee. An Option may be exercised during the lifetime of the Optionee only by the Optionee or by the Optionee’s guardian or legal representative or such other person who has the management of the Optionee’s estate. No Option or interest therein may be transferred, assigned, pledged or hypothecated by the Optionee or by the Optionee’s guardian or legal representative or such person who has the management of the Optionee’s estate, or during the Optionee’s lifetime, whether by operation of law or otherwise, or be made subject to execution, attachment or similar process.

If an Optionee’s Service terminates for any reason other than the Optionee’s death, then the Optionee’s Options shall expire on the earliest of the following occasions:

(ii) The date 30 days after the termination of the Optionee’s Service for any reason other than Disability, or such later date as the Board of Directors may determine; or

(iii) The date 12 months after the termination of the Optionee’s Service by reason of Disability, or such later date as the Board of Directors may determine.

The Optionee or his guardian or legal representative or such other person who has the management of the Optionee’s estate may exercise all or part of the Optionee’s Options at any time before the expiration of such Options under the preceding sentence but only to the extent that such Options had become exercisable before the Optionee’s Service terminated (or became exercisable as a result of the termination) unless otherwise determined by the Board of Directors in its sole discretion. The balance of such Options shall lapse when the Optionee’s Service terminates. In the event that the Optionee dies after the termination of the Optionee’s Service but before the expiration of the Optionee’s Options, all or part of such Options may be exercised (prior to expiration) by the Optionee’s personal representatives, but only to the extent that such Options had become exercisable before the Optionee’s Service terminated (or became exercisable as a result of the termination).

For purposes of Subsection (i) above, Service shall be deemed to continue while the Optionee is on a bona fide leave of absence, if such leave was approved by the Company in writing and if continued crediting of Service for this purpose is expressly required by the terms of such leave or by applicable law (as determined by the Company).

If an Optionee dies while the Optionee is in Service, then the Optionee’s Options shall expire on the earlier of the following dates:

(ii) The date 12 months after the Optionee’s death or such later date as the Board of Directors may determine.

All or part of the Optionee’s Options may be exercised at any time before the expiration of such Options under the preceding sentence by the Optionee’s personal representatives, but only to the extent that such Options had become exercisable before the Optionee’s death or became exercisable as a result of the death unless otherwise determined by the Board of Directors in its sole discretion. The balance of such Options shall lapse when the Optionee dies.

An Optionee, or his guardian, legal representative or such other person who has the management of the Optionee’s estate, or the personal representatives of an Optionee in the event of the death of an Optionee, shall have no rights as a shareholder with respect to any Shares covered by the Optionee’s Option until such person has been allotted and issued such Shares by filing a notice of exercise and paying the Exercise Price pursuant to the terms of such Option.

Within the limitations of the Plan, the Board of Directors may modify, extend or assume outstanding Options or may accept the cancellation of outstanding Options (whether granted by the Company or another issuer) in return for the grant of new Options for the same or a different number of Shares and at the same or a different Exercise Price. The foregoing notwithstanding, no modification of an Option shall, without the consent of the Optionee, impair the Optionee’s rights or increase the Optionee’s obligations under such Option.

The entire Exercise Price of Shares issued under the Plan shall be payable in cash or cash equivalents at the time when the Options are exercised, except as otherwise provided in this Section 6.

To the extent that a Share Option Agreement so provides and provided that the relevant requirements of the Companies Act, Chapter 50 of Singapore and the requirements of all other prevailing laws and regulations have been complied with, all or any part of the Exercise Price may be paid by surrendering Shares that are already owned by the Optionee. Such Shares shall be valued at their Fair Market Value on the date when the Option is exercised. The Optionee shall not surrender Shares in payment of the Exercise Price if such action would cause the Company to recognize compensation expense (or additional compensation expense) with respect to the Option for financial reporting purposes.

To the extent that a Share Option Agreement so provides, and in accordance with the rules and procedures established by the Board of Directors for this purpose and subject to applicable law, an Option may also be exercised through “cashless exercise” procedures approved by the Board of Directors involving a broker or dealer approved by the Board of Directors that affords an Optionee the opportunity to sell immediately some or all of the Shares underlying the exercised portion of the Option in order to generate sufficient cash to pay the Exercise Price and/or to satisfy withholding tax obligations related to the Option.

To the extent that a Share Option Agreement so provides, and in accordance with the rules and procedures established by the Board of Directors for this purpose and subject to applicable law, payment of the Exercise Price may be made all or in part by the delivery of an irrevocable direction to pledge Shares to a securities broker or lender approved by the Board of Directors, as security for a loan, and to deliver sufficient cash to pay the Exercise Price and/or to satisfy withholding tax obligations related to the Option.

In the event of a subdivision of the outstanding Shares, a declaration of a dividend payable in Shares, a declaration of an extraordinary dividend payable in a form other than Shares in an amount that has a material

effect on the Fair Market Value of the Shares, a consolidation of the outstanding Shares into a lesser number of Shares, a recapitalization, a reclassification, reorganization, merger, consolidation, combination or a similar occurrence, the Board of Directors shall make appropriate adjustments in one or more of (i) the number of Shares available for future grants under Section 4 hereof, (ii) the number of Shares covered by each outstanding Option or (iii) the Exercise Price under each outstanding Option.

Except as provided in this Section 7, an Optionee shall have no rights by reason of (i) any subdivision or consolidation of shares of any class, (ii) the payment of any dividend or (iii) any other increase or decrease in the number of shares of any class. Any issuance by the Company of shares of any class, or securities convertible into shares of any class, shall not affect, and no adjustment by reason thereof shall be made with respect to, the number or Exercise Price of Shares subject to an Option. The grant of an Option pursuant to the Plan shall not affect in any way the right or power of the Company to make adjustments, reclassifications, reorganizations or changes of its capital or business structure, to merge or consolidate or to dissolve, liquidate, sell or transfer all or any part of its business or assets.

Shares shall not be issued under the Plan unless the issuance and delivery of such Shares comply with (or are exempt from) all applicable requirements of law, including (without limitation) the U.S. Securities Act, all other securities laws and regulations, and the regulations of any exchange or other securities market on which the Company’s securities may then be traded.

Nothing in the Plan or in any right or Option granted under the Plan shall confer upon the Optionee any right to continue in Service for any period of specific duration or interfere with or otherwise restrict in any way the rights of the Company (or any Parent or Subsidiary employing or retaining the Optionee) or of the Optionee, which rights are hereby expressly reserved by each, to terminate his or her Service at any time and for any reason, with or without cause.

The Plan, as set forth herein, shall become effective on the date of its approval by the Company’s shareholders. The Plan shall terminate automatically 10 years after the date of the later of the Plan’s adoption by the Board or Directors or approval by the Company’s shareholders of an increase in the Plan Limit, and may be terminated on any earlier date pursuant to Section 10(b) hereof.

The Board of Directors may amend, suspend or terminate the Plan at any time and for any reason; provided, however, that any amendment of the Plan which increases the number of Shares available for issuance under the Plan (except as provided in Section 7 hereof), or which materially changes the class of persons who are eligible for the grant of ISOs, shall be subject to the approval of the Company’s shareholders. Shareholder approval shall not be required for any other amendment of the Plan.

No Option shall be granted and no Shares shall be issued under the Plan after the termination thereof, except upon exercise of an Option granted prior to such termination. The termination of the Plan, or any amendment thereof, shall not affect any Option previously granted under the Plan.

Except as expressly provided in this Plan, no person other than the Company or an Optionee shall have any rights to enforce any provision of this Plan under the Contracts (Rights of Third Parties) Act, Chapter 53B of Singapore.

The Plan is intended to qualify under Section 423 of the U.S. Tax Code; however, the Company assumes no responsibility, and shall not be liable, for tax consequences to any Participant in the event the Plan does not so qualify.

The Committee shall consist of two or more members of the Board of Directors appointed by and holding office at the pleasure of the Board of Directors.

(f) Governing Law. The Plan shall be construed in accordance with the laws of the Republic of Singapore.

(a) Purchase Periods. While the Plan is in effect, two Purchase Periods shall commence in each calendar year. The Purchase Periods shall consist of the six-month periods commencing on each 15 February and 16 August.

(b) Enrollment. Any individual who, on the day preceding an Offering Date, qualifies as an Eligible Employee may elect to become a Participant in the Plan for such Purchase Period by enrolling in accordance with

the method or methods prescribed for this purpose by the Committee. Any required enrollment form shall be filed with the Company at the location and by the means, including by written or electronic media, prescribed by the Committee by 14 February and 15 August of each calendar year, unless a later time for filing the enrollment form is set by the Committee for all Eligible Employees with respect to a given Purchase Period; provided, however, that with respect to any Eligible Employee hired during the four-week period prior to an Offering Date, the Eligible Employee may file the enrollment form with the Company at any time prior to the Offering Date. To the extent a Participant elects to pay for Company Shares by means of periodic payroll deductions, any required enrollment form shall set forth the percentage of the Participant’s Compensation (subject to Section 8(b) hereof) to be paid as contributions pursuant to the Plan. Participants may choose one of the following methods of payment for the Company Shares to be acquired on his or her behalf during the Purchase Period: periodic payroll deduction or lump sum cash payment; provided, however, that the Committee may, for any Purchase Period, prohibit either method of payment.

(c) Duration of Participation. Once enrolled in the Plan, a Participant shall continue to participate in the Plan until he or she ceases to be an Eligible Employee, withdraws from the Plan under Section 5(a) hereof or reaches the end of the Purchase Period in which his or her periodic payroll contributions were discontinued pursuant to Section 8(b) hereof. A Participant who withdraws from the Plan under Section 5(a) hereof may again become a Participant for any subsequent Purchase Period by following the procedure described in Section 3(b) hereof; provided; however, that he or she then is an Eligible Employee. A Participant whose employee contributions were discontinued automatically under Section 8(b) hereof shall automatically resume participation at the beginning of the earliest Purchase Period ending in the next calendar year; provided; however, that he or she then is an Eligible Employee.

(a) Amount of Contributions. To the extent a Participant elects to pay for the Company Shares by means of payroll deductions, the Participant shall designate on any required enrollment form the portion of his or her Compensation that he or she elects to contribute by payroll deduction for the purchase of Company Shares. Such portion shall be a whole percentage of the Participant’s Compensation, but not less than 1% nor more than 15%. Contributions to the Plan shall be made after payroll deductions for taxes and the Participant’s employee contributions in respect of retirement and welfare benefit plans and may be reduced, if necessary, to ensure that the aggregate of all such deductions does not exceed the Participant’s Compensation for the relevant payroll period.

(b) Payment of Lump Sum Cash Payments. If the lump sum cash payment alternative is selected, the lump sum payment must be paid by the Participant within the fifteen (15) days prior to the Purchase Date of the Purchase Period to which any required enrollment form is applicable, unless the Participant has previously elected to withdraw from participation in the Plan prior to the close of a Purchase Period as provided in Section 5(a) hereof.

(c) Frequency of Payroll Deductions. Payroll deductions, as designated by the Participant pursuant to Section 4(a) hereof, shall commence on the first regularly scheduled pay date following the Offering Date and shall occur on each pay date during the Participant’s participation in the Plan.

(d) Changing Contribution Rates. A Participant may on one occasion only during a Purchase Period increase or decrease the rate of his or her contributions with respect to the Purchase Period by completing and filing with the Company an appropriate form authorizing a change in the payroll deduction rate or lump sum payment, as applicable. The change shall be effective as of the beginning of the next payroll period following the date of the filing of the form, if the form is filed by 15 July and 15 January, and, if not, as of the beginning of the next succeeding Purchase Period. The new contribution rate shall be a whole percentage of the Participant’s Compensation, but not less than 1% nor more than 15%.

(a) Withdrawal. A Participant may elect to withdraw from the Plan prior to the close of a Purchase Period by filing the prescribed form with the Company at the prescribed location by 15 July or 15 January of each calendar year, as applicable. As soon as reasonably practicable thereafter, payroll deductions (if any) shall cease and the entire amount credited to the Participant’s Plan Account shall be refunded to him or her in cash, without interest, after deducting from such amount any expenses that were both incurred by the Company in maintaining the Participant’s Plan Account and earlier communicated to the Participant in writing. A Participant’s withdrawal from the Plan shall not have any effect upon his or her eligibility to re-enroll in the Plan for any subsequent Purchase Period by following the procedure under Section 3(b) hereof, subject to the requirements under Section 3(c) hereof, or to participate in any similar plan that may hereafter be adopted by the Company. No partial withdrawals shall be permitted.

(b) Re-Enrollment After Withdrawal. A former Participant who has withdrawn from the Plan shall not be a Participant until he or she re-enrolls in the Plan under Section 3(b) hereof, subject to the requirements of Section 3(c) hereof. Re-enrollment shall be effective only at an Offering Date.

(a) Termination of Employment. Termination of employment as an Eligible Employee for any reason, including death, shall be treated as an automatic withdrawal from the Plan under Section 5(a) hereof.

(b) Leave of Absence. For purposes of the Plan, the employment of a Participant shall not be deemed to terminate when such Participant goes on a military leave, a sick leave or another bona fide leave of absence, if the leave was approved by the Company in writing. Employment, however, shall be deemed to terminate 90 days after the Participant goes on a leave, unless a contract or statute guarantees his or her right to return to work. The employment of a Participant shall be deemed to terminate in any event when the approved leave ends, unless the Participant immediately returns to work.

(c) Death. In the event of a Participant’s death prior to a Purchase Date, the entire amount credited to his or her Plan Account shall, after deducting from such amount any expenses that were both incurred by the Company in maintaining the Participant’s Plan Account and earlier communicated to the Participant in writing, be paid, without interest, to a beneficiary designated by him or her for this purpose on the prescribed form or, if no beneficiary was designated, to the Participant’s estate. Such form shall be valid only if it was filed with the Company at the prescribed location before the Participant’s death. In the event of a Participant’s death subsequent to a Purchase Date but prior to the delivery to him or her of any Company Shares or cash remaining in his or her Plan Account, the Company shall deliver to the executor or administrator of the estate of the Participant such Company Shares and, after deducting any expenses that were both incurred by the Company in maintaining the Participant’s Plan Account and earlier communicated to the Participant in writing, the cash amount remaining in the Participant’s Plan Account.

(a) Plan Accounts. The Company shall maintain a Plan Account in the name of each Participant. Whenever an amount is deducted or collected from the Participant’s Compensation under the Plan, such amount shall be credited to the Participant’s Plan Account. To the extent required by all applicable laws, all amounts credited to Plan Accounts shall be held in trust for the Participants. To the extent not so required, amounts credited to Plan Accounts may be commingled with the Company’s general assets and applied to general corporate purposes. No interest shall be credited to Plan Accounts.

(b) Purchase Price. The Purchase Price for each Company Share purchased on the Purchase Date shall be the lower of:

(i) 85% of the Fair Market Value of such Company Share on the first Business Day in the applicable Purchase Period; or

(ii) 85% of the Fair Market Value of such Company Share on the last Business Day in the applicable Purchase Period.

Notwithstanding the foregoing, the Purchase Price for each Ordinary Share shall in no event be less than the par value of an Ordinary Share on the Purchase Date.

(c) Number of Company Shares Purchased. As of the Purchase Date, each Participant shall, subject to the provisions of this Section 7(c), be deemed to have elected to purchase the number of Company Shares calculated in accordance with this Section 7(c), unless the Participant has previously elected to withdraw from the Plan in accordance with Section 5(a). The amount then in the Participant’s Plan Account shall be divided by the Purchase Price, and the resulting number of Company Shares, rounded down to the nearest whole Company Share, shall be purchased from the Company with the funds in the Participant’s Plan Account. The foregoing notwithstanding and subject to the share limitations set forth in Sections 8(b) and 13(a), the maximum number of Company Shares that a Participant may purchase in each Purchase Period shall not exceed the number of Company Shares equal to the quotient arrived at by dividing US$12,500 by the Fair Market Value of a Company Share as of the Offering Date rounded down to the nearest whole Company Share, provided, however, that in no event shall the maximum number of Company Shares contemplated by the limit in this sentence exceed 10,000 Ordinary Shares or 1,000 ADSs, as the case may be. In the case of a Participant who elects to purchase Ordinary Shares, the Committee may determine with respect to all Participants who elect to purchase Ordinary Shares during the applicable Purchase Period that any quantity of Ordinary Shares fewer than 10 whole Ordinary Shares, as calculated under this Section 7(c), shall be rounded down to the next lower multiple of 10 whole Ordinary Shares. As a condition to the purchase by the Participant of Company Shares in accordance with this Section 7(c), the Participant may be required to deliver to the Company, on or before the last day of each Purchase Period, a cheque or cash in the amount reasonably required by the Company to satisfy the Company’s withholding obligations under applicable tax laws arising in connection with such purchase (unless the Company has no withholding obligation in respect of the Participant or unless the Company and the Participant shall have made other arrangements for deductions or withholding from the Participant’s salary, bonus or other income payable to the Participant by the Company provided such arrangements satisfy the requirements of applicable laws).

(d) Available Ordinary Shares Insufficient. In the event that the aggregate number of Company Shares that all Participants elect to purchase during any Purchase Period exceeds the maximum number of Ordinary Shares (including the number of Ordinary Shares represented by ADSs, in the case of Participants who elect to purchase ADSs) remaining available for issuance under Section 13(a) hereof, then the number of Company Shares to which each Participant is entitled shall be determined by multiplying the number of Ordinary Shares available for issuance by a fraction, the numerator of which is the number of Ordinary Shares that such Participant has elected to purchase (or number of Ordinary Shares represented by ADSs, in the case of a Participant who elects to purchase ADSs) and the denominator of which is the number of Ordinary Shares that all Participants have elected to purchase (including the number of Ordinary Shares represented by ADSs, in the case of Participants who elect to purchase ADSs), rounded down to the nearest whole Company Share. In the case of a Participant who elects to purchase Ordinary Shares, the Committee may determine with respect to all Participants who elect to purchase Ordinary Shares during the applicable Purchase Period that any quantity of Ordinary Shares fewer than 10 whole Ordinary Shares, as calculated under this Section 7(d), shall be rounded down to the next lower multiple of 10 whole Ordinary Shares.

(e) Issuance of Ordinary Shares. Subject to such consents or other required action of any competent authority under any regulations or enactments for the time being in force as may be necessary and subject to the compliance with the terms of the Plan and the Memorandum of Association and the Articles of Association of the Company, the Company shall, as soon as practicable after the applicable Purchase Date, allot the relevant Ordinary Shares and dispatch to the CDP the relevant Ordinary Share certificates by ordinary post or such other mode as the Committee may deem fit. The Company shall, as soon as practicable after such allotment and where

required, apply to any stock exchange(s) on which the Ordinary Shares are quoted or listed for permission to deal in and for quotation of such Ordinary Shares. Ordinary Shares that are allotted to a Participant on the Purchase Date shall be issued in the name of the CDP to the credit of the securities account of that Participant maintained with the CDP, the securities sub-account maintained with a CDP agent or the CPF investment account maintained with a CPF agent bank.

(f) Unused Cash Balances. Any amount remaining in the Participant’s Plan Account (i) that is (1) less than the Purchase Price for 10 whole Ordinary Shares (if the Committee determines in its discretion to apply the rounding procedures described in Sections 7(c) and 7(d) hereof), or (2) less than the Purchase Price for a whole ADS or Ordinary Share (if the Committee does not apply such rounding procedures) and (ii) that is not authorized by the Committee to be issued as a fractional share, shall be retained in the Plan Account for the next Purchase Period, subject to early withdrawal by the Participant as provided in Section 5(a) hereof, without interest. Any other amount remaining in the Participant’s Plan Account that represents the Purchase Price for whole Company Shares that could not be purchased by reason of the share limitations set forth in Section 7(c), 7(d), 8(b) or Section 13(a) hereof, in each case after deducting from such amount any expenses that were both incurred by the Company in maintaining such account and previously communicated to the Participant in writing shall be returned to the Participant.

(a) Five Percent Limit. Any other provision of the Plan notwithstanding, no Participant shall be granted a right to purchase Company Shares under the Plan if such Participant, immediately after his or her election to purchase such Company Shares, would own shares possessing more than 5% of the total combined voting power or value of all classes of shares of the Company or any Parent or Subsidiary.

(b) U.S. Dollar Limit. Any other provision of the Plan notwithstanding, no Participant shall be granted a right under the Plan that permits the Participant’s rights to purchase Company Shares under the Plan, together with other rights or options to purchase Company Shares or other shares of the Company under all other employee share purchase plans of the Company or any Parent or any Subsidiary subject to Section 423 of the U.S. Tax Code, to accrue at a rate which exceeds US$25,000 of the Fair Market Value of such Company Shares or other shares of the Company for each calendar year in which the purchase right is outstanding at any time. For the purpose of the limitation imposed by this Section 8(b): (i) the right to purchase Company Shares or other shares of the Company under a right or option accrues when the right or option (or any portion thereof) first becomes exercisable during the calendar year, (ii) the right to purchase Company Shares or other shares of the Company under a right or option accrues at the rate provided in the right or option, but in no case may such rate exceed US$25,000 of the Fair Market Value of such Company Shares or other shares of the Company for any one calendar year, and (iii) a right to purchase Company Shares or other shares of the Company that has accrued under one right granted pursuant to the Plan may not be carried over to any other right or option. This limitation shall be applied in accordance with Section 423(b)(8) of the U.S. Tax Code and the U.S. Treasury Regulations thereunder.

For purposes of this Section 8(b), the Fair Market Value of Company Shares that are or may be purchased pursuant to the Plan shall be determined in each case as of the Offering Date in which such Company Shares are purchased, and the Fair Market Value of Company Shares that are or may be purchased pursuant to all other employee share purchase plans of the Company or any Parent or any Subsidiary subject to Section 423 of the U.S. Tax Code shall be determined in each case at the time the option or right to purchase shares pursuant to such plan is granted. Employee share purchase plans not described in Section 423 of the U.S. Tax Code shall be disregarded for purposes of this Section 8(b). If a Participant is precluded by this Section 8(b) from purchasing additional Company Shares under the Plan, then his or her employee contributions shall automatically be discontinued and shall resume at the beginning of the earliest Purchase Period ending in the next calendar year (if he or she then is an Eligible Employee).

(c) Individuals Subject to Non-U.S. Jurisdictions; Trust. To the extent necessary to comply with the laws of any relevant jurisdiction, the Committee shall have the discretion to adopt, on behalf of the Company, one or more sub-plans applicable to separate classes of Eligible Employees who are subject to laws of jurisdictions outside of the United States; provided, however, that the adoption of any plan or sub-plan must be in accordance with the applicable stock exchange listing rules. Furthermore, to the extent necessary to comply with the laws of any relevant jurisdiction and consistent with the purposes of the Plan and the interests of the Company, the Committee may establish a trust in connection with the Plan or any other employee benefit plan of the Company.

Neither contributions credited to a Participant’s Plan Account nor any rights with regard to the exercise of a purchase right or to receive Company Shares under the Plan may be assigned, transferred, pledged or otherwise disposed of in any way (other than by will or the laws of descent and distribution) by the Participant. During his or her lifetime, a Participant’s right to purchase Company Shares hereunder is exercisable only by him or her. Any such attempt at assignment, transfer, pledge or other disposition shall be without effect, except that the Committee may treat such act as a voluntary election to withdraw from the Plan in accordance with Section 5(a) hereof.

Nothing in the Plan nor in any right granted under the Plan shall confer upon any Participant any right to continue in the employ of a Participating Company for any period of specific duration or interfere with or otherwise restrict in any way the rights of the Participating Companies or of the Participant, which rights are hereby expressly reserved by each, to terminate his or her employment at any time and for any reason, with or without cause.

A Participant shall have no rights as a shareholder with respect to any Company Shares that he or she may have a right to purchase under the Plan until such Company Shares have been purchased on the applicable Purchase Date.

Company Shares shall not be issued under the Plan unless the issuance and delivery of such Company Shares comply with (or are exempt from) all applicable requirements of law, including, without limitation, the U.S. Securities Act of 1933, as amended, the rules and regulations promulgated thereunder, U.S. state securities laws and regulations, and the regulations of any securities exchange or other securities market on which the Company’s securities may then be listed or traded.

(a) Authorized Ordinary Shares. Subject to adjustment pursuant to this Section 13, the aggregate number of Company Shares available for purchase under the Plan (including the number of Ordinary Shares represented by ADSs purchased under the Plan) shall not exceed 130 million Ordinary Shares.

(b) Anti-Dilution Adjustments. The following shall be adjusted proportionately by the Committee for any increase or decrease in the number of outstanding Company Shares resulting from a subdivision or consolidation of Company Shares or the payment of a share dividend, any other increase or decrease in such Company Shares effected without receipt or payment of consideration by the Company, the distribution of the shares of a Subsidiary to the Company’s shareholders or a similar event: (i) the aggregate number of Company Shares offered under the Plan; (ii) the Company Share limitation per Purchase Period described in Section 7(c) hereof;

(iii) the rounding procedures described in Sections 7(c) and 7(d) hereof; and (iv) the price of Company Shares that any Participant has elected to purchase. No adjustment or action described in this Section 13(b) or in any other provision of the Plan shall be authorized to the extent that such adjustment or action would cause (i) the Plan to fail to satisfy the requirements of Section 423 of the U.S. Tax Code and (ii) to the extent prohibited under applicable law, an Ordinary Share to be issued at a Purchase Price below the par value of an Ordinary Share.

(c) Corporate Transactions. In the event of a dissolution or liquidation of the Company, any Purchase Period then in progress shall terminate immediately prior to the consummation of such transaction, unless otherwise determined by the Board of Directors, and as soon as reasonably practicable thereafter, payroll deductions (if any) shall cease and the entire amount credited to a Participant’s Plan Account shall be refunded to him or her in cash, without interest, after deducting from such amount any expenses that are both incurred by the Company in maintaining such account and previously communicated to the Participant in writing. In the event of a Corporate Transaction, each purchase right outstanding under the Plan shall be assumed or an equivalent purchase right shall be substituted by the successor corporation or a Parent or Subsidiary of such successor corporation. In the event that the successor corporation refuses to assume or substitute for outstanding purchase rights in connection with a Corporate Transaction, each Purchase Period then in progress shall be shortened and a new Purchase Date shall be set (the “New Purchase Date”), as of which date any Purchase Period then in progress will terminate.

The Board of Directors may at any time and for any reason terminate or amend the Plan. Except as provided in Section 13 hereof, no termination of the Plan may affect purchase rights previously granted, provided; however, that the Plan or a Purchase Period may be terminated by the Board of Directors on a Purchase Date or by the setting of a New Purchase Date by the Board of Directors with respect to a Purchase Period then in progress if the Board of Directors determines that termination of the Plan or the Purchase Period or both is in the best interests of the Company and the shareholders or if continuation of the Plan, or the Purchase Period or both would cause the Company to incur adverse accounting charges as a result of a change after the effective date of the Plan in the generally accepted accounting rules applicable to the Plan. Except as provided in Section 13 hereof and in this Section 14, no amendment to the Plan shall make any change in any purchase right previously granted which adversely affects the rights of any Participant, unless such Participant has consented to such amendment.

The adoption of the Plan shall be subject to approval by the shareholders of the Company. Such shareholder approval shall be obtained in the manner and to the degree required under Applicable Laws. The Plan shall not become effective and no rights shall be granted under the Plan until the Plan is approved by the shareholders of the Company.

Except as otherwise expressly provided in this Plan, no person other than the Company or any Participant shall have any rights to enforce any provision of this Plan under the Contracts (Rights of Third Parties) Act, Chapter 53B of Singapore.

The Registrant’s Articles of Association provide that, subject to the Companies Act, Chapter 50 of Singapore, all of the Registrant’s directors, secretaries and other officers shall be entitled to be indemnified by the Registrant against all costs, charges, losses, expenses and liabilities incurred by them in the execution and discharge of their duties or in relation thereto, including any liabilities incurred by them in defending any proceedings, civil or criminal, which relate to anything done or omitted or alleged to have been done or omitted by them as a director, secretary or other officer of the Registrant. The Registrant’s Articles of Association further provide that none of the Registrant’s directors, secretaries or other officers shall be liable:

The indemnification provisions in the Registrant’s Articles of Association provide for indemnification of the Registrant’s officers and directors to the extent permitted under the Singapore Companies Act (Chapter 50) of Singapore.

The Registrant maintains directors and officers insurance providing indemnification for certain of the Registrant’s directors, officers, affiliates or employees for certain liabilities.

Opinions of Morgan Stanley Dean Witter Asia (Singapore) Pte and Credit Suisse First Boston LLC (attached as Annexes D and E, respectively, to the document filed as part of this registration statement).

(2) The undersigned Registrant hereby undertakes as follows: that prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this Registration Statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the undersigned Registrant undertakes that such offering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other Items of the applicable form.

(3) The Registrant undertakes that every prospectus (a) that is filed pursuant to paragraph (1) immediately preceding, or (b) that purports to meet the requirements of Section 10(a)(3) of the Act and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the Registration Statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new Registration Statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(4) Insofar as the indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

(5) The undersigned Registrant hereby undertakes to respond to requests for information that is incorporated by reference into the Prospectus pursuant to Items 4, 10(b), 11 or 13 of this Form, within one business day of

receipt of such request, and to send the incorporated documents by first-class mail or other equally prompt means and to arrange or provide for a facility in the U.S. for the purpose of responding to such requests. This includes information contained in documents filed subsequent to the effective date of the Registration Statement through the date of responding to the request.

(6) The undersigned Registrant hereby undertakes to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the Registration Statement when it became effective.

(7) The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant’s annual report pursuant to section 13(a) or section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

Pursuant to the requirements of the Securities Act of 1933, as amended, the Registrant certifies that it has duly caused this registration statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the Republic of Singapore, on the 2nd day of July, 2004.

Pursuant to the requirements of the Securities Act of 1933, as amended, this registration statement has been signed by the following persons in the capacities indicated below on the 2nd day of July, 2004.

Board of Directors, Classification and Rotation:	The Singapore Companies Act provides that a company shall have at least one director, who is ordinarily resident in Singapore. The STATS articles of association provide that the STATS	Under Delaware law, the certificate of incorporation or a stockholder-adopted bylaw of a Delaware corporation may provide for the classification of the board of directors in order to stagger the


	STATS Shareholder Rights	ChipPAC Stockholder Rights
	board of directors must have at least two members. No maximum number is fixed. Currently, the number of STATS directors is 11. Under the STATS articles of association, at each annual general meeting, one-third of the STATS directors for the time being, or, if the number of STATS directors is not a multiple of three, the number nearest to but not less than one-third, shall retire from office by rotation. The STATS directors to retire by rotation at an annual general meeting are those who have been longest in office since their last election or appointment. Retiring STATS directors are eligible for re-election. The STATS articles of association permit a director to appoint an alternate director to act in place of such director should such director be unable to perform such director’s duties as director for a period of time. Under Singapore law, the alternate director is not merely an agent of the director, but is accountable to the company for such alternate director’s actions as director during the period for which such alternate director acts as a director.	terms of directors. The term “classified board” generally means the specification of selected board seats for a term of more than one year (but not more than three years), with different classes of board seats coming up for election each year. The ChipPAC bylaws do not provide for a classified board, but rather provide for the election of all of the ChipPAC directors at every annual meeting. The ChipPAC bylaws provide that the number of ChipPAC directors shall be fixed by the vote of a majority of the total number of ChipPAC directors then in office, and such number is currently fixed at eight. The ChipPAC directors shall be elected by a plurality of the votes of the shares present in person or represented by proxy at the annual meeting and entitled to vote in the election of directors.

Removal of Directors:	Under the Singapore Companies Act, shareholders may remove a director of a public company by ordinary resolution, irrespective of any provisions in the company’s memorandum or articles of association or in any agreement between the company and the director, provided that where any director so removed was appointed to represent the interests of any particular class of shareholders or debenture holders the resolution to remove such director shall not take	Under Delaware law, stockholders holding the majority of shares entitled to vote at an election of directors may remove directors with or without cause unless the certificate of incorporation provides otherwise.

Filling Vacancies of the Board of Directors:	Under STATS articles of association, shareholders may, by ordinary resolution at a meeting appoint a person who is willing to be a director either to fill a casual vacancy or as an additional director. Under the STATS articles of association, the STATS board of directors also has the power to appoint a director to fill a casual vacancy or as an additional director, provided that such appointment will only last until the next annual general meeting of STATS, at which the director concerned may be re-elected, but such director shall not be taken into account in determining the number of directors chosen to retire by rotation at such meeting.	Delaware law provides that vacancies and newly created directorships may be filled by the affirmative vote of a majority of the directors then in office even though less than a quorum, or a sole remaining director, unless the certificate of incorporation or bylaws provide otherwise. The ChipPAC certificate of incorporation is consistent with Delaware law. Under the ChipPAC bylaws, nominations for election to the ChipPAC board of directors may be made at a meeting of stockholders (i) by the ChipPAC board of directors or (ii) by any ChipPAC stockholder who follows the procedures laid out in the ChipPAC bylaws. No person shall be eligible to serve as a ChipPAC director unless nominated in accordance with the procedures set forth in the ChipPAC bylaws.

Calling of Special Meetings of Shareholders:	Under Singapore law, an extraordinary general meeting of shareholders may be called by the board of directors whenever it sees fit and the board of directors is required to call such a meeting on the requisition of persons holding not less than 10% of the paid up share capital of the company having voting rights at shareholders’ meetings as of the date of the deposit of the requisition. Two or more shareholders holding not less than 10% of issued share capital may also call a meeting of the	Delaware law provides that a special meeting of stockholders may be called for any purpose or purposes by the board of directors or by such person or persons as may be authorized by the certificate of incorporation or by the bylaws.
