(b) Subject to applicable Law, Acquisition Sub expressly reserves the right to waive any Offer Condition or amend or modify the terms of the Offer by concurrent written notice to the Company and to the Stockholders, provided that (x) no such proposed amendment or modification shall be effective for any purpose if it could reasonably be expected to impose additional obligations or liability on the Stockholders with respect to the Offer or the consummation of the Offer other than as contemplated hereby,(y) any proposed amendment or modification that would require the amendment of any term of this agreement shall not be effective without such amendment having been made pursuant to Section 6, and (z) without the prior written consent of the Company and the Stockholders, Acquisition Sub shall not (i) reduce the number of shares of Company Common Stock subject to the Offer, (ii) reduce the consideration payable in the Offer, (iii) waive the Minimum Condition (as defined in Schedule C) or (iv) change the form of consideration payable in the Offer. Subject to Section 4, (i) Acquisition Sub may extend the Offer for a period of up to 30 days only if and to the extent such extension is approved by the FSC, and (ii) Acquisition Sub may make such changes to the Offer as are required in order to comply with Regulation 14E of the U.S. Securities Exchange Act of 1934, as amended.

(c) On or prior to the date of commencement of the Offer, Acquisition Sub shall file with the FSC and submit to the Market Observation Post System of Taiwan (“MOPS”) a Tender Offer Prospectus in due and proper form that complies in all material respects with the applicable form relating to the Offer (together with any supplements, amendments and exhibits thereto, and all deliveries, mailings and notices required by applicable Law, the “Offer Documents”). Acquisition Sub shall promptly correct any information in the Offer Documents if and to the extent that such information shall have become false or misleading in any material respect, and Acquisition Sub shall take all steps necessary to amend or supplement the Offer Documents and to cause the Offer Documents as so amended or supplemented to be timely filed with the FSC and published in the MOPS and to be timely disseminated to holders of Shares, in each case as and to the extent required by applicable FSC, TSE and MOPS rules and regulations.  Acquisition Sub shall give the Company, the Stockholders and their respective counsel a reasonable opportunity to review and comment on the Offer Documents and all amendments and supplements to the Offer Documents prior to their being filed with the FSC and published in the MOPS and disseminated to holders of Shares.  Acquisition Sub further hereby agrees to promptly provide the Company, the Stockholders and their respective counsel in writing with any comments Acquisition Sub or its counsel may receive from the FSC or the MOPS with respect to the Offer Documents promptly after the receipt of such comments, and shall promptly consult with and provide the Company, the Stockholders and their respective counsel a reasonable opportunity to review and comment on the response of Acquisition Sub to such comments prior to responding.

(d) Subject solely to the satisfaction or waiver by Acquisition Sub of the Offer Conditions in accordance with Section 2(b) hereof, Acquisition Sub shall promptly and in event within seven (7) business days after the then scheduled Expiration Date if at that time all of the Offer Conditions are satisfied (or waived by Acquisition Sub), accept for payment and pay for the shares of Company Common Stock validly tendered and not withdrawn pursuant to the Offer for the Offer Price. If Acquisition Sub is ordered by the FSC to amend the terms of the Offer according to applicable Law, Acquisition Sub shall promptly do so, and shall re-submit the Offer Documents and make a public announcement regarding such amendment, and the Expiration Date shall be re-started to count from the date Acquisition Sub re-submits the Offer Documents and makes such a public announcement.

(e) If, between the date of this Agreement and the first time at which Acquisition Sub accepts for payment and makes payment for any shares of Company Common Stock tendered pursuant to the Offer (the “Acceptance Time”), the outstanding shares of Company Common Stock are changed into a different number or class of shares by reason of any share issuance, share split, division or subdivision of shares, share dividend, reverse share split, consolidation of shares, reclassification, recapitalization or other similar transaction, then the Offer Price shall be adjusted accordingly.

Section 3. Agreement to Tender and Vote; Other Covenants of the Stockholders. Each Stockholder, solely as to itself and its own Subject Shares and not as to any other Stockholder or the Subject Shares of any other Stockholder, and Acquisition Sub, covenant and agree as follows:

(a) Agreement to Tender. Such Stockholder shall accept the Offer with respect to all the Subject Shares of such Stockholder and shall tender, on the Expiration Date, and Acquisition Sub shall accept for payment and shall pay for, all of such Subject Shares pursuant to the Offer and the terms of this Agreement if and only if (x) each of the prerequisites set forth in Schedule D attached hereto (the “Stockholder Prerequisites”) is satisfied (or such prerequisite is waived by Acquisition Sub) and (y) Acquisition Sub shall have delivered to such Stockholder written notice that the Stockholder Prerequisites have been satisfied (or waived by Acquisition Sub) (the “Stockholder Notice”) no later than one (1) business day prior to the Expiration Date (and which Stockholder Notice shall be presumed to confirm that the Stockholder Prerequisites remain satisfied as of the Expiration Date unless the Acquisition Sub delivers written notice to the contrary to each of the Stockholders prior to the tender of Subject Shares by any Stockholder, and if such notice to the contrary is delivered, then such Stockholder shall not so tender); provided, however, that in no event shall such Stockholder tender any Subject Shares into the Offer prior to the Expiration Date unless instructed to do so in the Stockholder Notice delivered by Acquisition Sub (which such Stockholder Notice may not be given by Acquisition Sub earlier than the 10^th business day after the Offer commences and in which case, if such instruction is given, such Stockholder shall accept the Offer with respect to all of the Subject Shares of such Stockholder on the date indicated in such instruction, and Acquisition Sub shall accept for payment and shall pay for, all of such Subject Shares at the Acceptance Time pursuant to Section 2(d)). Acquisition Sub shall be required to deliver the Stockholder Notice to the Stockholders no later than one (1) business day prior to the Expiration Date so long all of the Stockholder Prerequisite are satisfied (or waived by Acquisition Sub) as of such time (and which Stockholder Notice shall be presumed to confirm that the Stockholder Prerequisites remain satisfied as of the Expiration Date unless the Acquisition Sub delivers written notice to the contrary to each of the Stockholders prior to the tender of Subject Shares by any Stockholder, and if such notice to the contrary is delivered, then such Stockholder shall not tender); provided, that Acquisition Sub may elect to deliver the Stockholder Notice to the Stockholders earlier than the Expiration Date. Such Stockholder shall not withdraw any Subject Shares of such Stockholder tendered pursuant to the Offer unless (i) the Offer shall have been terminated in accordance with applicable Law or has expired without Acquisition Sub purchasing all shares of Company Common Stock tendered (and not validly withdrawn) pursuant to the Offer, or (ii) this Agreement shall have been terminated in accordance with its terms; provided, however, that such Stockholder shall have no obligation under this Agreement if the Offer Price is amended to less than NT$91.00 per share.

(b) Agreement to Vote in Favor of Merger. (1) At any meeting of the stockholders of the Company called to seek the Company Stockholder Approval or in any other circumstances upon which a vote, consent or other approval with respect to the Merger Agreement, any other agreement contemplated hereby or thereby, the Offer or the Merger, or any other transaction contemplated hereby or by the Merger Agreement is sought, such Stockholder, subject to the provisions of this Agreement, shall (i) if a meeting is held, appear at such meeting or otherwise cause the Subject Shares to be counted as present at such meeting for purposes of establishing a quorum and (ii) vote (or cause to be voted) the Subject Shares in favor of granting the Company Stockholder Approval.

The Stockholder shall not take or commit or agree to take any action inconsistent with the foregoing.

(3) Revoke Other Proxies. Such Stockholder represents that any proxies heretofore given by it in respect of its Subject Shares that may still be in effect are not irrevocable, and such proxies are hereby revoked.

(4) IRREVOCABLE PROXY; Solicitation of Proxies.

(i)     During the term of this Agreement and, in the event of termination of this Agreement pursuant to the final paragraph of Section 4, the Survival Period, to the extent permitted by the Securities and Exchange Law of Taiwan and regulations promulgated thereunder, each Stockholder hereby irrevocably grants to, and appoints, the Stockholders who are members of the Company Management, and any person designated in writing by the Company (including the Company’s securities agent), and each of them individually, as such Stockholder’s proxy and attorney-in-fact (with full power of substitution), for and in the name, place and stead of such Stockholder, to vote such Stockholder’s Subject Shares, or grant a consent or approval in respect of such Subject Shares in a manner consistent with this Section 3(b)(4)(i).

Upon the Acceptance Time, the rights and obligations of the parties to this Agreement (other than Section 3(i) which continues until such time as (1) Acquisition Sub has nominated for election at least a majority of directors of the Company and (2) such nominees have been elected as directors of the Company) shall terminate in their entirety.
