The failure to so notify the Indemnifying Party shall not relieve the Indemnifying Party of its obligations hereunder, except to the extent such failure shall have actually materially and adversely prejudiced the Indemnifying Party. If the Indemnifying Party does not notify the

Indemnified Party within thirty (30) days following the receipt of a notice with respect to any such claim that the Indemnifying Party disputes its indemnity obligation to the Indemnified Party for any Damages with respect to such claim, such Damages shall be conclusively deemed a liability of the Indemnifying Party and the Indemnifying Party shall promptly pay to the Indemnified Party any and all Damages arising out of such claim. If the Indemnifying Party has timely disputed its indemnity obligation for any Damages with respect to such claim, the parties shall proceed in good faith to negotiate a resolution of such dispute and, if not resolved through such negotiations, such dispute shall be resolved by arbitration determined pursuant to Section 10.09.

Section 10.02. Severability. Whenever possible, each provision of this Agreement shall be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability shall not affect any other provision or any other jurisdiction, and this Agreement shall be reformed, construed and enforced in such jurisdiction as if such invalid, illegal or unenforceable provision had never been contained herein.

Section 10.03. Complete Agreement. This Agreement, the ▇▇▇ and the RRA embody the complete agreement and understanding among the parties hereto with respect to the subject matter hereof and supersede any prior understandings, agreements or representations by or among the parties, written or oral, which may have related to the subject matter hereof in any way.

Section 10.04. Counterparts. This Agreement may be executed in separate counterparts, each of which shall be an original and all of which taken together shall constitute one and the same agreement. Signatures in the form of facsimile or electronically imaged “PDF” shall be deemed to be original signatures for all purposes hereunder.

Section 10.05. Assignments. This Agreement is personal to each of the parties hereto. No party may assign or delegate any rights or obligations hereunder without first obtaining the written consent of each other party hereto; provided that the Purchaser may assign any rights or obligations hereunder to any of its Affiliates without obtaining the prior written consent of the other parties hereto.

Section 10.07. Amendment. The provisions of this Agreement may be amended, or modified only upon the prior written consent of all parties hereto. The failure of any party to

enforce any of the provisions of this Agreement shall in no way be construed as a waiver of such provisions and shall not affect the right of such party thereafter to enforce each and every provision of this Agreement in accordance with its terms.

Section 10.08. Governing Law. This Agreement, the rights and obligations of the parties hereto, and all claims or disputes relating hereto, shall be governed by and construed in accordance with the laws of the State of New York, without regard to the conflict of law rules of such state.

Any dispute arising out of or in connection with this Agreement shall be referred to and finally resolved by arbitration under the administered rules (the “Rules”) of the Hong Kong International Arbitration Centre (the “HKIAC”), which Rules are deemed to be incorporated by reference into this Section 10.09. For the purposes of such arbitration:

(a) the number of arbitrators shall be three (the “Arbitration Board”). The Company and the Purchaser shall each select one arbitrator. All selections shall be made within thirty (30) days after the selecting party gives or receives, as the case may be, the demand for arbitration. The two arbitrators so appointed shall jointly agree on a third arbitrator, who shall be the chairman of the Arbitration Board. If the said two arbitrators are unable to agree upon the appointment of a third arbitrator within thirty (30) days after the parties have appointed their respective arbitrators, then such third arbitrator shall be appointed by the HKIAC;

(b) the seat of the arbitration shall be in Hong Kong and the language to be used shall be English; and

The parties hereto shall be entitled to specific performance from any court of law or equity of competent jurisdiction (without posting any bond or other security) in order to enforce any tribunal award pursuant to any arbitration proceeding hereunder.

Section 10.10. Expenses. Except as otherwise provided herein, all costs and expenses incurred in connection with this Agreement, or any amendment or waiver hereof, and the transactions contemplated hereby shall be paid by the party incurring such costs or expenses.

Except for those Persons expressly entitled to indemnification pursuant to Article 8, there are no third party beneficiaries of this Agreement and nothing in this Agreement, express or implied, is intended to confer on any Person other than the parties hereto and the Persons expressly entitled to indemnification pursuant to Article 8 and their respective successors, heirs and assigns, any rights, remedies, obligations.
