                   Party B: Xinjiang Rundi Bio-tech Co., Ltd.

         WHEREAS:

     To safeguard the legitimate rights and interests of Party A and Party B, in
accordance  with the Contract  Law of the  People's  Republic of China and other
relating laws and administrative  regulations,  in the principle of reciprocity,
mutual benefit and  development,  for the subject matter that Party A authorizes
Party B to be the exclusive  distributor in Xinjiang Uygur Autonomous Region for
Party A's products, both parties agree as follows:

         1. Appointment and flow direction control

     1.1 Party A appoints Party B as the exclusive distributor in Xinjiang Uygur
Autonomous Region  (hereinafter  referred to as the "Designated  Territory") for
Party  A's  products.  Party  A's  products  include  "Yi Mu Ling"  water  flush
fertilizer,  "Pu Guang Fu" liquid fertilizer for plant's leaves, "Zhi Guang You"
compound  microorganism  fertilizer and organic  fertilizer.  Both parties agree
that under the same  conditions for  distribution  of Party A's other  follow-up
fertilizer  products in such  territory  Party A shall give first rank to choose
Party B as the exclusive distributor and this Contract shall apply.

     1.2  Party  B's  appointment  as the  exclusive  distributor  for Party A's
products  shall  be  effective  from  Janurary  1,  2007 to  December  31,  2009
(hereinafter  referred to as the  "Distribution  Year").  If Party B reaches the
sales  objective  provided  herein upon  expiration of such term,  Party A shall
continue  the  appointment  of  Party  B as  the  exclusive  distributor  in the
designated  territory,  otherwise  Party A may decide at its own  discretion  to
notify Party B in writing of whether to extend the appointment of Party B as the
exclusive distributor. If Party B accepts this proposal, then the appointment of
Party B as the exclusive distributor of Party A's products shall be extended.

     1.3 The areas for Party B or its any sub-tier distributor who purchases the
products  directly or indirectly  from Party B to distribute  Party A's products
shall be limited to the designated territory.  Except as otherwise prior written
consent is acquired from Party A, Party B may not distribute  Party A's products
at the areas other than the designated  territory,  nor appoint any  individual,
company or distributor outside the designated territory for any reason or in any
manner.

     1.4 If Party B or its any sub-tier  distributor  who purchases the products
directly or indirectly from Party B breaches the stipulations  regarding product
flow control in selling or transferring the products, Party B shall be deemed as
breach of contract, Party A shall have the right to request Party B to stop such
noncompliance  immediately,  and  Party B shall  pay to  Party A the  liquidated
damages at 15% of the sales value of the  nonconforming  sales. If Party B fails

receiving  the goods or finds  shortage  in  quantity,  and it is  necessary  to
return, replace or supplement the goods, Party B shall give notice in writing to

representative  confirms  the  responsibility  is with  Party A, the  action  to

raised within the due time, all the goods shall be deemed acceptable.

     5.3 After receiving Party B's objection or request of compensation, Party A
shall given written  response within seven days after receiving the objection or
request of  compensation,  if Party A's failure to do so shall be deemed as that

shortage.

     6.1  Within  five days  after a  purchase  order is  signed,  Party B shall
advance to Party A 50% of the total  payment  for the goods  under the  purchase
