REPRESENTATIONS AND WARRANTIES

2.1 Representations and Warranties. Each Investor represents and warrants to each other Investor that it is duly authorized to execute and deliver this Agreement, to perform its obligations under and to consummate the transactions contemplated by this Agreement, and that this Agreement is a valid and legally binding agreement of such Investor, enforceable in accordance with its terms.

2.2 Reliance on Other Investors. Each Investor shall be entitled to rely upon the representations and warranties and agreements of each other Investor in the Subscription Agreement.

ARTICLE III

BOARD OF DIRECTORS; VOTING

3.1. Appointment of Directors. As long as the Co-Investors own in the aggregate at least 10% of the outstanding Shares, the Co-Investors shall be entitled to select one of the Board directors (the "Co-Investor Designee") whom AOF is entitled to appoint pursuant to Section 2.1 of the Shareholders Agreement (the "AOF Designees"). The director to be selected by the Co-Investors shall be determined by the Co-Investors holding a majority of the Shares then held by the Co-Investors. AOF agrees to appoint each Co-Investor Designee as an AOF Designee pursuant to the Shareholders Agreement. AOF agrees that in connection with any Transfer of Shares owned by it (other than in a Public Sale), AOF will ensure that the Transferee of such Shares will assume AOF's obligation under this Section 3.1 if, following such Transfer, AOF would not be able to fulfill such obligation. Following an issue of Shares upon exercise of the Warrants or issue of Shares to employees of any ASAT Company pursuant to an exercise of stock options granted to such employee, the 10% threshold above shall be reduced to reflect the dilutive effect or reduction of the numbers of Shares held by the Co-Investors as a result of such event.

3.2. Voting by Co-Investor Director. With respect to any matter voted upon by the Board, the Co-Investors agree to cause the Co-Investor Designees to vote in accordance with the instructions of AOF except with respect to matters as to which the AOF Designees are not entitled to vote under applicable law or pursuant to 6.3 of the Shareholders Agreement, in which case such director may vote in accordance with the Co-Investors' instructions (subject to the

requirements of the Shareholders Agreement).

3.3. Voting of ASAT Shares. Subject to Section 3.4, with respect to any matter voted upon by the shareholders of ASAT, each Co-Investor agrees to vote, in person or by proxy, all Shares owned by it, at any annual or extraordinary general meeting of shareholders or by consensual action of shareholders without a meeting, in accordance with the instructions of AOF.

3.4. No Conflict. Nothing in this Article III shall require a Co-Investor or a Co-Investor Designee to vote in conflict with the Shareholders Agreement or applicable law or in favor of a resolution or other action that would adversely affect the rights or preferences of any class of Shares held by such Co-Investor and would not in the same manner adversely affect the rights or preferences of Shares of the same class held by other Shareholders.

3.5. Information. Any Co-Investor Designee shall be entitled to disclose Confidential Information to the Co-Investors as co-investors referred to in Section 6.1 of the Shareholders Agreement.

ARTICLE IV

TRANSFER OF SHARES

4.1. Restrictions on Sale of Shares. Except for (a) Transfers to the Co-Investors' Permitted Transferees pursuant to Section 3.3 of the Shareholders Agreement, (b) Transfers pursuant to a Public Sale and (c) Transfers required as a result of the exercise by any Shareholder of drag along rights pursuant to Section 4.3 of the Shareholders Agreement, each Co-Investor agrees that it shall not Transfer Shares that it owns until it has first complied with the provisions of this Article IV.

4.2 Sale of Shares. If any Co-Investor desires to Sell Shares to a Third Party in a Sale subject to Section 4.1 of the Shareholders Agreement, such Co-Investor shall comply with the provisions therein. Such Co-Investor shall advise each other Investor of its intention to make such a Sale at least 14 days before such Co-Investor gives any other Shareholder a Right of First Offer Notice in respect thereof. Such Co-Investor shall indicate in its Right of First Offer Notice that the offer therein is being made to other Shareholders subject to the prior right of CAIP and AOF to purchase all such Shares as Permitted Transferees. If CAIP or AOF gives a Section 4.1 Purchase Notice in respect of such Shares, then all such Shares shall be Sold exclusively to either or both of them as Permitted Transferees. If CAIP and AOF fail to give a Section 4.1 Purchase Notice within the Right of First Offer Notice Period, then the provisions of Section 4.1 of the Shareholders Agreement shall apply to such Sale without regard to this Section 4.2.

4.3 Drag Along Rights. If CAIP and AOF propose to Sell all their Shares to a Third Party, they may require all (and not less than all) the Co-Investors to Sell all (and not less than all) their Shares together with CAIP's and AOF's Shares as follows:

(a) At least 14 days before giving a Right of First Offer Notice as provided in Section 4.3(b) hereof, CAIP and AOF shall advise the Co-Investors of their intention to compel the Co-Investors to sell their Shares to such Third Party and their intention to take the other actions provided for in this Section 4.3.

(b) CAIP and AOF shall provide to all other Shareholders a right of first offer for all (and not less than all) CAIP's and AOF's Shares in accordance with Section 4.1 of the Shareholders Agreement. The Right of First Offer Notice shall state that if the offer therein is not accepted, then CAIP and AOF shall include all the Shares then owned by Co-Investors in any Sale to a Third Party as provided below. If one or more Offerees shall deliver a Section 4.1 Purchase Notice to CAIP and AOF accepting such offer, then CAIP and AOF (and the Co-Investors, if applicable) shall Sell their Shares to such Offeree(s) as provided in such notice and Section 4.1 of the Shareholders Agreement.

(c) If no Offeree shall have delivered a Section 4.1 Purchase Notice in respect of such offer, CAIP and AOF may Sell all their Shares to a Third Party as provided in Section 4.1 of the Shareholders Agreement and, in the event of such a Sale, shall include in such Sale all Shares then owned by the Co-Investors at the same price per Share and on the same terms specified in the Right of First Offer Notice. CAIP and AOF shall deliver to the Co-Investors promptly after agreeing to such a Sale written notice thereof and of their decision to compel the Co-Investors to sell their Shares in accordance herewith and a copy of all agreements containing the terms and conditions pursuant to which the Shares are proposed to be Sold. To the extent that CAIP and/or AOF receives any fee or other payment as compensation for exercising their drag along rights under Section 4.3 of the Shareholders Agreement and causing the Co-Investors' Shares to be included in a Sale to a Third Party, the Co-Investors shall receive a pro rata portion (in the proportion provided in Section 5.2(a)) of such fee or payment.

(d) If the proposed Sale to a Third Party hereunder would be a Section 4.3 Sale, then before the Sale to a Third Party may be consummated, CAIP and AOF shall (if required by the shareholders Agreement) offer to QPL (and not the Co-Investors) a right of first refusal with respect to all the Investors' Shares to be included in such Sale in accordance with Sections 4.3(b) through (e) of the Shareholders Agreement. If QPL delivers a Section 4.3 Purchase Notice, then all Investors shall Sell all their Shares to QPL as provided in Section 4.3(d) and (e) of the Shareholders Agreement.

(e) Each Co-Investor (i) shall be required to participate in a Sale on the terms and conditions set forth in the notice delivered to them by CAIP and AOF pursuant to (c) above, (ii) deliver to the Third Party the certificates representing such Shares on or before the closing of such Sale and collect directly from the Third Party the consideration to be paid for such Shares, and (iii) otherwise cooperate in good faith to effect such Sale, including (if necessary) Selling their Shares to CAIP or AOF as a Permitted Transferee in exchange for such consideration in order to effect the purposes of this Section 4.3. It is understood that the number of Investor Shares to be sold in any Sale under this Section 4.3 shall be reduced to the extent that QPL exercises its tag-along rights in respect of such Sale under Section 4.2 of the Shareholders Agreement.

(f) The last sentence of Section 4.3(k) of the Shareholders Agreement shall in no respect restrict CAIP's and AOF's rights herein. Notwithstanding anything contained in this Section 4.3, there shall be no liability on the part of CAIP or AOF to any Co-Investor if any Sale of Shares to a Third Party pursuant to this Section 4.3 is not consummated for whatever reason. Any decision as to whether to Sell Shares to a Third Party shall be at the sole and absolute discretion of CAIP and AOF.
