TERMINATION FEE

3.1 If the Merger is not consummated and the Parent Termination Fee becomes payable by Parent pursuant to Section 8.06(b) of the Merger Agreement, and any party hereto is a Defaulting Party (as defined below), notwithstanding anything provided under the Limited Guaranties, (a) the Defaulting Party shall be responsible for the entire Parent Termination Fee payable by Parent under Section 8.06(b) of the Merger Agreement and shall promptly pay an amount equal to the Parent Termination Fee to Parent by wire transfer of same day fund within one (1) Business Day following the termination of the Merger Agreement pursuant to Section 8.03(a) or Section 8.03(b) thereof; (b) in the event any of the Company’s fees and expenses shall become payable by Parent in accordance with Section 8.06(d) of the Merger Agreement, the Defaulting Party shall be responsible for all such fees and expenses payable by Parent; and (c) in the event that a Non-Defaulting Party’s (or the respective Guarantor’s) liabilities under the relevant Limited Guarantee become due and payable, the Defaulting Party shall indemnify such Non-Defaulting Party (or the respective Guarantor) in full for all payments made by, and all fees and out-of-pocket expenses incurred by, such Non-Defaulting Party (or the respective Guarantor) under such Limited Guarantee (the obligations of the Defaulting Party under this Section 3.1, collectively, the “Default Obligations”). If there is more than one Defaulting Party, each Defaulting Party shall be responsible for its Pro Rata Portion of the Default Obligations. A Defaulting Party’s “Pro Rata Portion” for the purposes of this Section 3.1 is a fraction, the numerator of which is such Defaulting Party’s Contemplated Ownership Percentage and the denominator of which is the aggregated Contemplated Ownership Percentage of all Defaulting Parties.

3.2 If the Merger is not consummated and the Parent Termination Fee becomes payable by Parent pursuant to Section 8.06(b) of the Merger Agreement, but no party is a Defaulting Party, then each party who (or whose Affiliate) also executes a Limited Guarantee shall be responsible for its (or its Affiliate’s) Guaranteed Percentage (as defined in the respective Limited Guarantee) of (i) Parent Termination Fees under Section 8.06(b) and (ii) Company’s fees and expenses under Section 8.06(d) of the Merger Agreement ((i) and (ii) collectively, the “Guaranteed Obligations”) in accordance with and subject to the terms and conditions of the Limited Guarantee executed by such party.

3.3 A “Defaulting Party” is a party hereto, the failure of whom or whose Affiliate to perform its obligation under this Agreement or, to the extent it is a party, the Support Agreement or the Equity Commitment Letter, results in the failure of the Merger to consummate. A “Non-Defaulting Party” is a party hereto who is not a Defaulting Party.

3.4 The parties shall be entitled to receive any termination, break-up or other fees or amounts payable to Parent by the Company pursuant to the Merger Agreement, to be allocated ratably in proportion to their respective Contemplated Ownership Percentages, net of the costs and expenses incurred by the Consortium in connection with the Transaction, including the fees, expenses and disbursements of Consortium Advisors retained by the Consortium (but other than fees and costs of any Separate Advisors who were retained by a party in accordance with Section 4.5 unless otherwise agreed to by the parties in writing).

In the event the Founder terminates a Failing Investor’s participation in the Transactions, the amount of such Failing Investor’s Equity Commitment shall be offered to new investors in such amounts as may be determined by the Founder.

7.2 Amendment. Any provision of this Agreement may be amended or waived if, and only if, such amendment or waiver is in writing and signed by each party hereto.

7.3 Severability. Any term or provision of this Agreement which is invalid or unenforceable in any jurisdiction shall, as to that jurisdiction, be ineffective to the extent of such invalidity or unenforceability without rendering invalid or unenforceable the remaining terms and provisions of this Agreement in any other jurisdiction. If any provision of this Agreement is so broad as to be unenforceable, such provision shall be interpreted to be only as broad as is enforceable.

7.4 Remedies. Except as otherwise provided herein, any and all remedies herein expressly conferred upon a party will be deemed cumulative with and not exclusive of any other remedy conferred hereby, or by law or equity upon such party, and the exercise by a party of any one remedy will not preclude the exercise of any other remedy. No failure or delay on the part of any party hereto in the exercise of any right hereunder will impair such right or be construed to

be a waiver of, or acquiescence in, any breach of any representation, warranty or agreement herein, nor will any single or partial exercise of any such right preclude other or further exercise thereof or of any other right. The parties hereby acknowledge and agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached, and damages alone would not be sufficient remedy for any actual or threatened breach of this Agreement and that each party shall be entitled to seek the remedy of injunction, specific performance and other legal and equitable relief for any breach of this Agreement (without posting a bond or other security) in additional to any other remedies available to it at law or in equity.

7.5 Announcement.

7.7 Governing Law; Dispute Resolution; Jurisdiction. This Agreement shall be interpreted, construed and governed by and in accordance with the laws of New York without regard to the conflicts of law principles thereof. Subject to the last sentence of this Section 7.7, any action arising out of or relating to this Agreement or its subject matter (including a dispute regarding the existence, validity, formation, effect, interpretation, performance or termination of this Agreement) shall be submitted to HKIAC and resolved in accordance with the Administrative Arbitration Rules of HKIAC.
