During the last five years, to the knowledge of the Reporting Persons, none of the Reporting Persons’ directors or executive officers, (a) has been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or (b) has been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

On February 10, 2004, STATS, Camelot Merger, Inc., a Delaware corporation and a wholly owned subsidiary of STATS (“Merger Sub”), and ChipPAC entered into an Agreement and Plan of Merger and Reorganization (the “Merger Agreement”).

Pursuant to the Merger Agreement, and subject to the conditions set forth therein (including approval of the shareholders of STATS and ChipPAC, receipt of a private letter ruling from U.S. tax authorities relating to the tax treatment of the Merger (as defined below) for ChipPAC stockholders (the “U.S. Private Letter Ruling”), certain regulatory approvals and other customary conditions), Merger Sub will merge with and into ChipPAC, with ChipPAC as the surviving corporation (the “Merger”). As a result of the Merger, each issued and outstanding share of ChipPAC Class A Common Stock, other than those shares of ChipPAC Class A Common Stock held by STATS, Merger Sub, any other subsidiary of STATS, ChipPAC or any subsidiary of ChipPAC, will be canceled and converted into the right to receive 0.87 (the “Exchange Ratio”) American Depositary Shares of STATS (“STATS ADSs”), each of which represents the right to receive ten ordinary shares, par value S$0.25 per share, of STATS.

As an inducement to STATS to enter into the Merger Agreement and in consideration thereof, certain stockholders of ChipPAC, including members of the Bain Group and the CVC Group (each as defined in the Merger Agreement), the directors of ChipPAC and certain officers of ChipPAC (each, a “Stockholder” and collectively, the “Stockholders”),

entered into a Voting Agreement with STATS (the “Voting Agreement”). In addition, the Stockholders granted to STATS, acting through its board of directors, an irrevocable proxy with respect to the shares covered by the Voting Agreement.

References to, and descriptions of, the Merger, the Merger Agreement and the Voting Agreement set forth herein are qualified in their entirety by reference to the copies of the Merger Agreement and the Voting Agreement included as Exhibits 1 and 2, respectively, to this Statement, which are incorporated by reference herein in their entirety where such references and descriptions appear.

As described in Item 3 above, pursuant to the Merger Agreement and subject to the conditions set forth therein (including approval of the shareholders of STATS and ChipPAC, receipt of the U.S. Private Letter Ruling, certain regulatory approvals and other customary conditions), Merger Sub will merge with and into ChipPAC and ChipPAC will become a wholly owned subsidiary of STATS. Once the Merger is consummated, Merger Sub will cease to exist as a corporation and all of the business, assets, liabilities and obligations of Merger Sub will be merged into ChipPAC with ChipPAC remaining as the surviving corporation (the “Surviving Corporation”).

As an inducement to STATS to enter into the Merger Agreement and in consideration thereof, STATS and the Stockholders entered into the Voting Agreement. Each Stockholder has, by its execution of the Voting Agreement, agreed that at every meeting of the stockholders of ChipPAC, however called, and at every adjournment thereof, and in every action by consent of the stockholders of ChipPAC, such Stockholder shall, provided that such Stockholder has not received notice from STATS (which notice may be delivered at any such meeting) stating STATS’ intention to exercise the Proxy (as defined below) at such meeting, appear at any such meeting or otherwise cause all shares of ChipPAC Class A Common Stock beneficially owned by it (with respect to each Stockholder, 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 contemplated by the Merger Agreement 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 STATS, against any action, proposal, agreement or transaction, including, but not limited to, any Competing Transaction (as defined in the Merger Agreement), other than the Merger Agreement and the Merger, the purpose or effect of which would be expected to prevent, delay, postpone or materially adversely affect the Merger.

Concurrently with the execution of the Voting Agreement, each Stockholder delivered to STATS a proxy in the form attached as Exhibit B to the Voting Agreement (the “Proxy”), which such Stockholder agreed shall be irrevocable to the fullest extent permissible by law, with respect to the Shares.

The beneficial ownership of shares of ChipPAC Class A Common Stock is acquired pursuant to the Voting Agreement and the Proxy, which was entered into in connection

with the Merger Agreement. The purpose of the Voting Agreement is to assist STATS and ChipPAC in consummating the Merger and the other transactions contemplated by the Merger Agreement.

Upon consummation of the Merger, (i) the directors of Merger Sub shall become the directors of the Surviving Corporation, (ii) the officers of Merger Sub shall be the officers of the Surviving Corporation, (iii) the Certificate of Incorporation of Merger Sub in effect at the Effective Time (as defined in the Merger Agreement) shall be the Certificate of Incorporation of the Surviving Corporation, except that at the Effective Time Article I of the Certificate of Incorporation shall be amended to read as follows: “The name of the corporation is STATS ChipPAC, Inc.”; (iv) the name of the Surviving Corporation will be STATS ChipPAC, Inc., and (v) the by-laws of Merger Sub in effect at the Effective Time shall be the by-laws of the Surviving Corporation.

If the Merger is consummated as planned, the ChipPAC Class A Common Stock will be eligible for termination of registration pursuant to Section 12(g)(4) of the Securities Exchange Act of 1934, as amended, and will cease to be authorized to be quoted on The Nasdaq Stock Market, Inc.’s National Market (“Nasdaq”).

(a)-(b) As a result of the Voting Agreement, the Reporting Persons may be deemed to be the beneficial owners of 18,167,837 shares of ChipPAC Class A Common Stock (all of which are outstanding as of February 10, 2004), constituting 18.7% of the issued and outstanding shares of ChipPAC Class A Common Stock, and may be deemed to have the shared power to vote such shares in the manner described in Item 4. However, the Reporting Persons are not entitled to any rights as a stockholder of ChipPAC as to such shares, apart from such limited voting rights. The Reporting Persons do not have the power to dispose of such shares. The calculation of the foregoing percentage is based on the number of shares of ChipPAC Class A Common Stock outstanding as of January 30, 2004 (as represented by ChipPAC in the Merger Agreement).

Except as disclosed in this Item 5(a)-(b), neither the Reporting Persons nor, to the best of their knowledge, any of the persons listed on Schedule A to this Statement beneficially owns any shares of ChipPAC Class A Common Stock or has the right to acquire any shares of ChipPAC Class A Common Stock.

The filing of this Statement shall not be construed as an admission by the Reporting Persons that they are, for purposes of Section
13(d) of the Exchange Act, the beneficial owner of shares of ChipPAC Class A Common Stock owned by the Stockholders.

(c) Except as disclosed in this Statement, none of the Reporting Persons nor, to its knowledge, any of the persons listed on Schedule A to this Statement has effected any transaction in the ChipPAC Class A Common Stock during the past 60 days.

(d) Other than as described herein, to the knowledge of the Reporting Persons, the Stockholders have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the Shares beneficially owned by the Reporting Persons.

References to, and descriptions of, the Merger Agreement and the Voting Agreement set forth herein are qualified in their entirety by reference to the copies of the Merger Agreement and the Voting Agreement included as Exhibits 1 and 2, respectively, to this Statement, which are incorporated by reference herein in their entirety where such references and descriptions appear.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer.

In addition to containing agreements regarding Stockholders voting their Shares, the Voting Agreement subjects the Stockholders’ Shares to certain restrictions on transfer.

Pursuant to the Voting Agreement, until termination of the Voting Agreement in accordance with its terms, each Stockholder has agreed that, except as contemplated by the Voting Agreement and the Merger Agreement, such Stockholder shall not 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 (as defined in the Merger Agreement) of any nature whatsoever with respect to, any of such Stockholder’s Shares or any outstanding principal amount of ChipPAC’s 8% Convertible Subordinated Notes due 2011 or 2.50% Convertible Subordinated Notes due 2008 (collectively, the “Company Securities”) (or agree or consent to, or offer to do, any of the foregoing). Notwithstanding anything to the contrary contained in the Voting Agreement, 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 U.S. Income Tax Regulations (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. Pursuant to the Voting Agreement, STATS has agreed 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.

Pursuant to the Voting Agreement, until the date that is 90 days after the date of the Effective Time, each Stockholder has agreed 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 STATS ordinary shares or STATS ADSs (or agree or consent to, or offer to do, any of the foregoing) (the “Limitations on Sale”); provided, however, (i) each Stockholder may transfer STATS ordinary shares or STATS ADSs to an affiliate of such Stockholder if such affiliate agrees in writing to comply with the Limitations on Sale; (ii) each Stockholder may sell, during any three-month period, such number of STATS ordinary shares (whether in the form of STATS ordinary shares or STATS ADSs) equal to the maximum number of STATS 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 of 1933, as amended, assuming that the STATS 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 STATS ordinary shares or STATS ADSs to any transferee in a transaction consummated in accordance with any private placement exemption from the registration requirement of the Securities Act if such transferee agrees in writing to comply with the Limitations on Sale; and (iv) each Stockholder listed on Exhibit C to the Voting Agreement may transfer STATS ordinary shares or STATS 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.
