Party A and Party B hereby agree to enter into this contract for the advance

      Registration No.: Pu 2004132389, with land size of 222,318.40 square
      meters for the usage of technical research.

      The commercial building is located at Capital of Leaders (East District)
      and the structure is made of armored concrete. The constructed building
      shall have 3 floors above ground and no floors below ground.

      The above mentioned commercial building shall be subject to the advance
      sale provisions of the Real Estate Transfer Measure of Shanghai. The
      advance sale has been authorized by the Shanghai Pudong New Area
      Construction Bureau. (Advance Sale Approval No.: Pudong New Area (2005) Yu
      Zi No. 0000723)

-     Party B has purchased from Party A the building located at Room 101 and
      Room 102 (multi-story), 1st Floor, Building 3, Building 4, Building 5 and
      Building 6, No. 1387 Zhang Dong Road, Capital of Leaders (East District)
      (hereinafter referred to as the "Building"). The government has authorized
      the usage of the building for office work.

      Party A's temporary measurement of the constructed floorage of the
      Building is 12,636.93 square meters, of which the interior is 11,723.84
      square meters and public use is 913.09 square meters. The Building's
      constructed height is 4.50, 3.90 meters.

-     Party B has purchased the Building at a unit price (not including
      decoration cost) of RMB 9,000.00 yuan (nine thousand yuan) per constructed
      square meter.

      According to Party A's temporary measurement of the constructed floorage
      of the Building, the aggregate purchase price is preliminarily set at RMB
      113,732,370.00 yuan (one hundred thirteen million, seven hundred thirty
      two thousand, three hundred and seventy yuan).

-     The aggregate purchase price (excluding decoration and equipment expenses)
      paid by Party B includes the price of the Building and the land use right
      associated with the Building. Except in the case that the temporary
      measurement differs from the as-measured constructed floorage of the
      Building, the aggregate purchase price set forth in this contract shall be
      unchanged.

                                       1
<PAGE>

-     If Party B does not make payment according to the schedule and timing set
      forth in this contract, then Party B shall pay a penalty to Party A in the
      amount of 0.05% of the outstanding balance for each day after the due
      date. The penalty shall be calculated starting the second day after the
      due date until full payment is received. If the payment has been overdue
      for more than 30 days, Party A can choose the following course of action.

      In addition to paying interest (the interest rate shall be determined
      according to the similar duration for deposits with the People's Bank of
      China), Party B shall pay the penalty to Party A and the duties of the
      contract will continue to be performed. If the payment has been overdue
      for more than 60 days, Party A has the right to terminate this contract
      and to deduct the penalty and interest from the payments already made by
      Party B to Party A. The remaining balance shall then be returned to Party
      B. If the payments already made by Party B to Party A are not sufficient
      to settle the penalty and interest, then Party B shall pay Party A within
      five days of receiving written notice (hereinafter referred to as the
      "Notice of Termination Period") from Party A. During the Notice of
      Termination Period, if the breach of contract continues, the penalty and
      interest will continue to accrue. If the breach of contract by Party B
      results in loss to Party A and the loss is greater than the penalty, then
      Party B shall compensate Party A the difference between the loss and
      penalty.

-     After the signing of this contract, Party A shall not change the
      construction design plan. If Party A needs to make changes to the design
      plan, Party A must receive written consent from Party B and relevant
      government approvals. Party A shall enter into an amendment to this
      contract with Party B within 15 days of receiving the written consent.

      If Party A does not receive written consent from Party B to change the
      design plan of the Building, Party B has the right to terminate this
      contract.

-     Party A shall not change the layout of the office park unless it receives
      written consent from Party B.

      If Party A does not receive written consent from Party B to change the
      layout of the office park, Party B has the right to request Party A to
      restore the office park to its original condition. If the office park
      cannot be restored to its original condition, Party A shall pay to Party B
      an amount of 5.00% of the aggregate purchase price.

-     Party A shall transfer the Building to Party B before March 30, 2006
      except due to force majeure.

-     If Party A does not transfer the Building to Party B in accordance with
      the terms of this contract, then Party A shall pay a penalty to Party B in
      the amount of 0.05% of the payments already made to Party A for each day
      after the due date. The penalty shall be calculated starting the second
      day after the transfer date until the transfer has occurred. If the
      transfer has been overdue for more than 30 days, Party B can choose the
      following course of action:

      Party A shall pay the penalty to Party B and the duties of the contract
      will continue to be performed. If the transfer has been overdue for more
      than 60 days, Party B has the right to terminate this contract. In
      addition to returning the payments already made by Party B with interest
      (the interest rate shall be determined according to the People's Bank of
      China for deposits of similar duration as the period from the date of the
      receipt of the purchase payment to the date of contract termination),
      Party A shall pay a penalty to Party B (the penalty period shall be
      calculated from the second day after the transfer date set forth in this
      contract until Party A has returned the payments from Party B with
      interest).

-     The risk and liability of the Building shall be passed from Party A to
      Party B following the date of the transfer of the Building. If Party B
      does not complete the inspection and transfer

                                       2
<PAGE>

      procedures by the date set forth, Party A shall provide Party B with
      written notice to do so. If Party B does not complete the inspection and
      transfer procedures according to the dates set forth in the written
      notice, then the risk and liability of the Building shall be transferred
      from Party A to Party B on the second day following the date set forth in
      the written notice.

-     Party A warrants that at the time of the transfer of the Building to Party
      B, there shall be no mortgage, property right or financial obligation on
      the Building. If, after the transfer of the Building, the condition is not
      in accordance with Party A's warranty, then Party A shall be fully
      responsible.

-     At the time that Party A transfers the Building, the Building shall have
      been deemed adequate following inspection. If the Building's decoration
      and equipment is not to the standards set forth in this contract, Party B
