Technology
Party C: Qingdao Siwei Chemical Co., Ltd


In line with the principle of reciprocity and mutual benefit and the operational
mechanism of combining "academic research with production", the three parties A,
B and C hereby, in light of the issue of exploitation of nano calcium carbonate,
enter into the following agreements:

1.    Party A entrusts Party B to conduct  research and development for the nano
      calcium  carbonate  products  produced  by  Party A,  including  Polyvinyl
      Chloride (PVC),  Polypropylene  (PP),  Polyethylene (PE), ABS, BOPP, BOPE,
      Compound  Agglomerate  of Nano Calcium  Carbonate,  General  Thermoplastic
      Colophony,  Non-dripping Film for Greenhouses,  Colophony Products, and so
      on.  Meanwhile,   Party  A  entrusts  Party  B  to  provide  the  relevant
      consultation and technological services relating to the technology of nano
      calcium  carbonate  for clients of Party A to assist them in their efforts
      to increase their market shares.
2.    Party B accepts the  entrustment  from Party A,  conducting  researches of
      technical  modification  and  application  for the nano calcium  carbonate
      products,  guiding their industrial applications,  and providing technical
      services for the sales of Party A.
3.    The term of the  contract is five years.  Party A pays Party B the project
      expenditure  for   researching  and  exploiting  nano  calcium   carbonate
      amounting  to RMB  60,000  (sixty  thousand)  yuan as the  expenditure  of
      experiment fee, scientific consultation fee and traveling expenses, and so
      on. The  expenditure  shall be paid in two  separate  payments.  The first
      payment in the amount of RMB 20,000  (twenty  thousand) yuan shall be paid

      the amount of RMB 40,000  (forty  thousand)  yuan shall be paid off within
      one year.  After three years,  Party A shall  properly pay more  technical
      service  fee to Party B according  to the  operating  conditions.  Party B
      shall  succeed in  developing  one  application  technology in one special
      field within one year after signing this contract.

4.    The modifying agent used in nano calcium carbonate by Party C shall not be
      sold to any other nano  calcium  carbonate  manufacturer  within two years
      after successful cooperation with Party A on modification and application.
      Party C shall  guarantee  the  supply by  preferential  prices and Party A
      shall not cooperate with any other  modifying  agent  manufacturer  of the
      same kind within two years.
5.    As for the  modifier  used by  Party C in nano  calcium  carbonate,  after
      successful application tests by Party A's customers, Party A promises that
      the annul  purchase  amount  for the year  2003  shall not be less than 60
      tons, with the desirable amount of 90 tons; the annual purchase amount for
      the year 2004 shall not be less than 100 tons,  with the desirable  amount
      of 150 tons.  The  terms of the  cooperation  between  Party C and Party A
      shall not be disclosed to any other parties.
6.    Party A  provides  Party  B with  the  expenditure  for  exploitation  and
      application of nano calcium  carbonate.  Once the project is  successfully
      completed,  the resulting technological  achievement shall belong to Party
      A. Party B shall not disclose this  information to any other party without
      the consent of Party A.
