THE DATANG FURTHER SUBSCRIPTION

Reference is made to the announcement by the Company dated 8 November 2008 and the Investor Announcement relating to, among other things, the potential exercise of the pre-emptive right and subscription of the Datang Pre-emptive Securities by Datang.

Datang has indicated in writing to the Company that it wishes to subscribe for the Datang Pre-emptive Securities, pursuant to which the Company and Datang entered into the Datang Further Subscription Agreement on 5 May 2011 under which Datang will subscribe for (i) 84,956,858 Convertible Preferred Shares at a price equivalent to the Investor Subscription Price of HK$5.39 per Convertible Preferred Share (the "Datang Pre-emptive Preferred Shares") and (ii) 16,991,371 Warrants at an exercise price of HK$5.39 per Warrant (the "Datang Pre-emptive Warrants" and, together with the Datang Pre-emptive Preferred Shares, the "Datang Pre-emptive Securities"). The issue of the Datang Pre- emptive Securities to Datang is conditional on the obtaining of the approval of Independent Shareholders and necessary governmental approvals.

The Datang Pre-emptive Preferred Shares represent (i) approximately 3.1% of the existing issued share capital of the Company as at the Latest Practicable Date (assuming full conversion thereof); and (ii) approximately 2.7% of the issued share capital of the Company as enlarged by the issue of the Investor Initial Preferred Shares and the Datang Pre-emptive Preferred Shares (assuming full conversion thereof).

The Datang Further Subscription Price of HK$5.39 which is reflective of an effective conversion price of HK$0.539 per Ordinary Share (based on the initial Conversion Rate) represents (i) a discount of approximately 28.1% to the closing price of HK$0.75 per Ordinary Share as quoted on the Stock Exchange on 5 May 2011, being the last full trading day immediately before the execution of the Datang Further Subscription Agreement; (ii) a discount of approximately 25.3% to the average closing prices of approximately HK$0.72 per Ordinary Share as quoted on the Stock Exchange for the last five consecutive trading days up to and including 5 May 2011; and (iii) a discount of approximately 20.9% to the average closing prices of approximately HK$0.68 per Ordinary Share as quoted on the Stock Exchange for the last ten consecutive trading days up to and including 5 May 2011.

The Datang Warrant Preferred Shares (if issued pursuant to full exercise by Datang of the Datang Pre-emptive Warrants) represent (i) approximately 0.6% of the existing issued share capital of the Company as at the Latest Practicable Date (assuming full conversion thereof); and (ii) approximately 0.5% of the issued share capital as enlarged by the Investor Subscription and the Datang Further Subscription, assuming a full exercise of the Investor Warrants and the Datang Pre-emptive Warrants (assuming full conversion thereof).

The exercise price of HK$5.39 per Datang Warrant is equivalent to the Datang Subscription Price for the Datang Pre-emptive Preferred Shares and is reflective of an effective conversion price of HK$0.539 per Ordinary Share (based on the initial Conversion Rate), which represents (i) a discount of approximately 28.1% to the closing price of HK$0.75 per Ordinary Share as quoted on the Stock Exchange on 5 May 2011, being the last full trading day immediately before the execution of the Datang Further Subscription Agreement; (ii) a discount of approximately 25.3% to the average closing prices of approximately HK$0.72 per Ordinary Share as quoted on the Stock Exchange for the last five consecutive trading days up to and including 5 May 2011; and (iii) a discount of approximately 20.9% to the average closing prices of approximately HK$0.68 per Ordinary Share as quoted on the Stock Exchange for the last ten consecutive trading days up to and including 5 May 2011.

PRE-EMPTIVE RIGHTS OF TSMC

The Company has notified TSMC in accordance with the terms of the TSMC Share and Warrant Issuance Agreement in connection with the Investor Subscription. TSMC has notified the Company that it will not exercise its pre-emption rights in respect of the Investor Subscription and the Datang Further Subscription.

REASONS FOR, AND BENEFITS OF, THE DATANG SUBSCRIPTION

The Company is of the view that the Datang Further Subscription will strengthen the relationship between Datang and the Company and provide additional source of funding for the Company's needs beyond the equity capital raised through the Investor Subscription. The Company has been informed by Datang that it continues to view its holding in the Company as a long term strategic investment, and that it will not dispose of the Ordinary Shares held by it in any significant way.

On this basis, the Directors (including the independent non-executive Directors) consider that, subject to the opinion of Guangdong Securities, the terms of the Datang Further Subscription are fair and reasonable and in the interests of the Company and the Shareholders as a whole.

USE OF PROCEEDS

It is estimated that the net proceeds from the issue of the Datang Pre-emptive Preferred Shares will be approximately US$58.3 million.

It is estimated that the net proceeds upon exercise of the Datang Pre-emptive Warrants would be approximately US$11.7 million.

Datang currently holds 19.07% of the entire existing issued share capital of the Company.

The Datang Further Subscription constitutes a connected transaction of the Company under Chapter 14A of the Listing Rules. The Datang Further Subscription is subject to reporting, announcement and independent shareholders' approval requirements under Chapter 14A of the Listing Rules. Accordingly, the Datang Further Subscription is subject to approval of the Independent Shareholders at the EGM. To the best of the Directors' knowledge, information and belief, having made all reasonable enquiries, apart from Datang and its associates (as defined in the Listing Rules), no other Shareholder of the Company will be required to abstain from voting on the resolutions for approving the Datang Further Subscription Agreement, the Datang Warrant Agreement, the Further Special Mandate and the transactions contemplated thereunder at the EGM.

Pursuant to the Listing Rules, an Independent Board Committee (consisting of all the independent non-executive Directors of the Company who have no direct or indirect interest in the Datang Further Subscription and the Further Special Mandate, other than, where applicable, being a Shareholder of the Company) has been established to advise the Independent Shareholders as to whether the respective terms of the Datang Further Subscription Agreement, the Datang Warrant Agreement and the Further Special Mandate are fair and reasonable, whether the entering into of the Datang Further Subscription Agreement, Datang Warrant Agreement and the proposal for the grant of the Further Special Mandate are in the interests of the Company and the Shareholders as a whole and to advise the Independent Shareholders on how to vote, taking into account the recommendations of Guangdong Securities.

The Independent Board Committee has approved the appointment of Guangdong Securities as the independent financial adviser to make recommendations to the Independent Board Committee and Independent Shareholders as to whether the respective terms of the Datang Further Subscription Agreement, the Datang Warrant Agreement and the Further Special Mandate are fair and reasonable and the reasons thereof, whether the entering into of the Datang Further Subscription Agreement and the Datang Warrant Agreement are in the interests of the Company and the Shareholders as a whole, and to advise the Independent Shareholders as to whether they should vote in favour of the Datang Further Subscription and the Further Special Mandate.

Capital

On a liquidation, dissolution, winding up (whether voluntary or involuntary) or return or reduction of capital of the Company (but not on conversion of the Convertible Preferred Shares or any repurchases by the Company of any Convertible Preferred Shares or Ordinary Shares) the assets of the Company available for distribution among the members will be applied first in paying to the holders of the Convertible Preferred Shares and holders of other preference shares of the Company an amount in repayment of capital equal to the amount paid up or credited as paid up on such shares in priority to:

(A) any payment to the holders of Ordinary Shares; and

(B) any other obligations ranking pari passu with the claims of the holders of Ordinary

Conversion right

The holders of the Convertible Preferred Shares will have the right at any time to convert (in whole or in part) their Convertible Preferred Shares into fully paid Ordinary Shares at the Conversion Rate (which shall be for a minimum amount of 70,000,000 Convertible Preferred Shares or, if less than 70,000,000 Convertible Preferred Shares are then held by Datang, all of such Convertible Preferred Shares).

Mandatory Conversion Date

The Convertible Preferred Shares will be mandatorily converted into Ordinary Shares at the then applicable Conversion Rate on the day immediately following the expiry of twelve months commencing from the Investor Closing Date as if the holder of the Convertible Preferred Shares has elected to convert its Convertible Preferred Shares into Ordinary Shares on the mandatory conversion date.

Adjustment to Conversion Rate

The initial Conversion Rate will be ten Ordinary Shares per Convertible Preferred Share

(subject to adjustments as described below).

The initial Conversion Rate is subject to adjustment upon the occurrence of certain prescribed events, among other things, capitalisation of profits or reserves, consolidations, sub-divisions and re-classifications of shares, capital distributions, issue of shares or other securities, and the issue of a new class of shares carrying voting rights.

In the event of any issue of any Ordinary Share or any securities which by their terms are convertible into or exchangeable for, or carry right(s) of subscription for, any Ordinary Share, the Conversion Rate in force immediately before such issue will be adjusted to compensate the holders of Convertible Preference Shares by reference to the lowest of:

(i) the reference price per Ordinary Share which initially is HK$0.5390 (subject to adjustment as described in this section);

(ii) the amount which represents:

a. in respect of any rights issue of Ordinary Shares by the Company, 90% of the relevant theoretical ex-rights price for an Ordinary Share under that rights issue;

b. in respect of any issue of securities which by their terms are convertible into or exchangeable for, or carry right(s) of subscription for, Ordinary Share(s):

(1) in the case of options, warrants or similar instruments, the aggregate of the subscription price or premium for such instrument and the initial exercise price at which the holder of such instrument may subscribe for Ordinary Shares;

(2) in the case of convertible bonds or convertible shares or similar instruments, the initial conversion price at which such instrument may be converted into Ordinary Shares; or

(3) in any other case, the aggregate price paid and initially payable by the subscriber of such securities in order to receive Ordinary Shares; and

c. in respect of any other issue of Ordinary Shares by the Company, the relevant issue price for an Ordinary Share under that issue;

(iii) the amount which represents a discount of 10% to the arithmetic average of the daily volume weighted average price for an Ordinary Share as shown on the VAP page of Bloomberg for the:

a. ten consecutive trading days immediately after the date on which the relevant issue is announced; or

b. in the case of a rights issue, ten consecutive trading days immediately after the ex- rights date; or

c. if the reference price to determine the issue price is based on share prices for a period after the relevant issue is announced, all the trading days during that period.

The adjustment will become effective immediately following the date of the issuance of the new securities.

No adjustment to the Conversion Rate will be made which has the effect or result of: (i) reducing the initial Conversion Rate upon the issue of the Convertible Preferred Shares, except upon any consolidation of Ordinary Shares or any corporate exercise with the effect of increasing the nominal value of the Ordinary Shares; or (ii) any Ordinary Share, upon conversion, falling to be issued at a price below the nominal value of the Ordinary Share.

Voting

The Convertible Preferred Shares will entitle the holders thereof to receive notice of, attend and vote at any meeting of members of the Company. Each Convertible Preferred Share will confer on its holder such number of voting rights as if the Convertible Preferred Share had been converted into Ordinary Shares.

Consent

Except with the consent or sanction of at least 75 per cent. of the vote of the holders of the Convertible Preferred Shares given at a separate class meeting, no resolution may be made by the Company to amend the terms of the Convertible Preferred Shares.

Transferability

The Convertible Preferred Shares will be freely transferrable save as provided for under the terms of the Datang Further Subscription Agreement.

Redemption

The Convertible Preferred Shares are non-redeemable.
