WITNESSETH:

     WHEREAS, the parties have entered into the Agreement; and

     WHEREAS, pursuant to and in accordance with Section 8.03 of the Agreement, the parties wish to amend the Agreement as set forth in this Amendment;

     NOW, THEREFORE, in consideration of the rights and obligations contained herein, and for other good and valuable consideration, the adequacy of which is hereby acknowledged, the parties agree as follows:

     Section 1. Closing Deliveries by the Purchaser. Section 2.06 of the Agreement is amended in its entirety to read as follows:

     “SECTION 2.06. Closing Deliveries by the Purchaser. (a) At the Closing, the Purchaser shall deliver to the Company, the Founders or the Sellers (as applicable):

     (i) to each Seller an amount set forth opposite such Seller’s name on Column A of Exhibit C hereto in cash in U.S. dollars by wire transfer in immediately available funds to the bank account designated by such Seller;

     (ii) a true and complete copy, certified by the Secretary or an Assistant Secretary of the Purchaser, of the resolutions duly and validly adopted by the Board of Directors of the Purchaser evidencing (i) its authorization and approval of the execution and delivery of this Agreement and the consummation of the transactions contemplated hereby and (ii) its authorization of the issuance of Purchaser Ordinary Shares to be issued to the Sellers pursuant to paragraph (b) of this Section 2.06;

     (iii) a certificate of the Secretary or an Assistant Secretary of the Purchaser certifying the names and signatures of the officers of the Purchaser authorized to sign this Agreement and the other documents to be delivered hereunder; and

     (iv) a certificate of a duly authorized officer of the Purchaser certifying as to the matters set forth in Section 6.01(i).

     (b) Within ten (10) days after the Closing, the Purchaser shall deliver to each Seller a share certificate representing the number of Purchaser Ordinary Shares set forth opposite such Seller’s name on Column B of Exhibit C hereto in the name of such Seller.”

     Section 2. Purchase Price. Section 2.02(e) is amended by adding a sentence as follow:

     “No 2004 Additional Consideration or 2005 Additional Consideration shall be payable if (i) any of the conditions set forth in Sections 6.02(iv), (v) and (viii) of the Agreement shall have not been satisfied prior to April 30, 2004 or (ii) any of the conditions set forth in Section 6.02(xi) shall have not been satisfied prior to December 31, 2004, each according to the terms of the Agreement. The Sellers and the Purchaser agree that the Purchaser may withhold and deduct all or a portion of the 2004 Additional Consideration or the 2005 Additional Consideration against all Losses arising out of or resulting from Wang Xing’s failure, prior to December 31, 2004, to hold or obtain the appropriate ICP license described in Section 6.02(xi). The Purchaser agrees to use its reasonable best efforts to assist Wang Xing in its application for the ICP license described in clause (ii) of Section 6.02(xi).”

     Section 3. Updated Disclosure Schedule. The Disclosure Schedule to the Agreement is amended and updated in its entirety by the disclosure schedule attached to this Amendment.

     Section 4. Assignment. This Amendment may not be assigned by operation of law or otherwise without the express written consent of the parties hereto (which consent may be granted or withheld in the sole discretion of each party); provided, however, that the Purchaser may assign this Amendment or any of its rights and obligations hereunder to one or more Affiliates of the Purchaser without the consent of other parties.

     Section 5. No Third Party Beneficiary. This Amendment shall be binding upon and inure solely to the benefit of the parties hereto and their permitted assigns and nothing herein, express or implied, is intended to or shall confer upon any other Person, including, without limitation, any union or any employee or former employee of the Company, any legal or equitable right, benefit or remedy of any nature whatsoever, including, without limitation, any rights of employment for any specified period, under or by reason of this Agreement.

     Section 6. Entire Agreement. This Amendment constitutes the entire agreement of the parties hereto with respect to the subject matter hereof and supersedes all prior agreements and undertakings, both written and oral, among the parties hereto with respect to the subject matter hereof. Except as amended by this Amendment, the Agreement shall continue in full force and effect.

     Section 7. Severability. If any term or other provision of this Amendment is invalid, illegal or incapable of being enforced by any Law or public policy, all other terms and provisions of this Amendment shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated by this Amendment is not affected in any manner materially adverse to any party. Upon such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Amendment so as to effect the original intent of the parties as closely as possible in an acceptable manner in order that the transactions contemplated by this Amendment are consummated as originally contemplated to the greatest extent possible.

     Section 8. Counterparts. This Amendment may be executed and delivered (including by facsimile transmission) in one or more counterparts, and by the different parties hereto in separate counterparts, each of which when executed shall be deemed to be an original but all of which taken together shall constitute one and the same agreement.
