               the applicable laws of the PRC.

     1.2  The Borrower agrees to accept such loan provided by the Lender and
          hereby agrees and warrants that such loan shall be used only for the
          investment in the Borrower's Company for the business development of
          the Company. Without the Lender's prior written consent, the Borrower
          shall not use the amount of such loan for any other purpose or
          transfer or pledge its equity interest in the Borrower's Company to
          any other third party.

     1.3  The Lender and the Borrower jointly agree and confirm that the
          Borrower shall repay the loan only by transferring all of the
          Borrower's equity in the Borrower's Company to the Lender or to any
          other person (legal person or natural person) designated by the
          Lender.

     1.4  The Lender and the Borrower hereby jointly agree and confirm that any
          proceeds raised from the transfer of Borrower's equity in the
          Borrower's Company shall be used to repay the Lender, for the
          consideration of the loan provided by the Lender, in such manner as
          designated by the Lender in accordance with this Agreement and the
          Agreement shall terminate thereupon.

     1.5  The Lender and the Borrower hereby jointly agree and confirm that the
          Lender is entitled to, but is not obliged to, at any time, purchase or
          designate any other person (legal person or natural person) to
          purchase all or part of Borrower's equity in the Borrower's Company at
          any price determined by Both Parties, subject to the permission of the
          law.

          The Borrower warrants to issue an irrevocable power of attorney to

          Agreement. However, if the transfer price shall exceed the principal
          amount of the loan hereunder, the amount in excess of the principal
          amount of the loan shall be deemed the interest payable on such loan
          under this Agreement, which shall be paid to the Lender by the
          Borrower.
