Rights Agreement with Xiangcai Securities and submitted the application for the
transfer of trust beneficial rights to Zhong Rong Trust in order to transfer
the trust beneficial rights and all rights and obligations under the Special
Trust Scheme to Xiangcai Securities at a total consideration of RMB2.1 billion.
