Dear sir or madam:

We refer to the certificates of deposit pledge agreement dated [date] July 2010 between Tianjin New Highland Science Development Co., Ltd.

This document is the Additional Pledge Commitments referred to in Clause 2.2 (Additional pledge) of the Pledge Agreement. The terms in bold used in the Additional Pledge Commitments shall have the same meanings as defined in the Pledge Agreement.

As the consideration for the Secured Parties to continue to provide or maintain the loan limits or sign or maintain various related agreements and arrangements, and as the security interests for securing the payment on time by the Pledgor of all Secured Obligations and its performance of all its other obligations under the Transaction Finance Document, in accordance with the Real Right Law of the People’s Republic of China (物权法), the Guarantee Law of the People’s Republic of China and other laws and regulations of China, the Pledgor, as the rightful owner of the New CD (with specifics listed in the following attachment), hereby pledges the New CD and its rights to collect all principals, interests and any other amounts of whatever nature and relevant rights and interest to the Security Agent who acts in the interests of the Secured Parties, which are the beneficiaries of the pledge interests and rights under the Additional Pledge Commitments.

The Pledgor shall, within 5 Business Days upon depositing any additional amounts into the Onshore Cash Collateral Account or making an early withdrawal from a Pledged CD as per requirement of the Security Agent (as the case may be), provide to the Security Agent, a New CD, relevant signature specimens or passwords and confirmation of the New CD. The Pledgor shall, to the best of its ability, ensure that the Security Agent receives, within 90 days from a change of the

balance of the Onshore Cash Collateral Account or a Pledged CD (as the case may be) and for the purpose of the pledge of the New CD, the relevant approval registration and filing documents from the Approving Authorities, Security Registration Authorities and the Filing Authorities (including, for avoidance of confusion, relevant documentations for any changes in the approval, registration and filing status), or documents giving evidence that such approval, registration and filing cannot be obtained, or postal evidences that the full set of application materials required for the approval, registration and filing purposes have been submitted to the Approving Authorities, Security Registration Authorities and Filing Authorities.

With respect to the pledge of New CDs established by the Pledgor in other circumstances, the Pledgor shall, to the best of its ability, ensure that the Security Agent receives, within 90 days from the signing of the Additional Pledge Commitments and for the purpose of the pledge of the New CDs, the relevant approval registration and filing documents from the Approving Authorities, Security Registration Authorities and the Filing Authorities (including, for avoidance of confusion, relevant documentations for any changes in the approval, registration and filing status), or documents giving evidence that such approval, registration and filing cannot be obtained, or postal evidences that the full set of application materials required for the approval, registration and filing purposes have been submitted to the Approving Authorities, Security Registration Authorities and Filing Authorities.

A New CD [date/No./amount] is the new certificate of deposit set up after the change of the certificate of deposit amount (if applicable), and the Additional Pledge Commitments shall replace the pledge established on the aforementioned CD.
