<PAGE>

In accordance  with the  provisions of Contract Law of the People's  Republic of
China and after  discussions  and  negotiations  about  the  development  of the
process of producing nano calcium carbonate by micro-mixing reactor based on the
existing  technology  of producing  nanometer  granule by  micro-mixing  reactor
developed by Party B, the two parties agree to enter into this contract.

I. The Content, Form and Requirements of the Target Technology:

Based on the existing  production  conditions provided by Party A, Party B shall
carry out the study of the  producing  method of nano  calcium  carbonate by the
micro-mixing  reactor,  find the proper  reacting  condition,  and carry out the
tests on small-scale  test,  pilot scale  experiment and commercial test for the
realization of industrial production.

1. The process of producing nano calcium carbonate by micro-mixing reactor

Based on the raw materials  provided by Party A, Party B shall find out the laws
by studying how the flow rate,  reaction  temperature and the  concentration  of
white lime milk will affect the size and appearance of the obtained nano calcium
carbonate  and the flow law inside  the  micro-mixing  reactor,  in order to get
prepared  for  designing  the  equipment  for  pilot  scale  experiments.  After
finishing  the above  technical  experiments,  Party B shall  submit a  research
report,  and  discuss  with  the  technical  personnel  from  Party A about  the
feasibility of pilot scale experiments.

2.  Determination  of the reacting  conditions  and key  parameters  of relevant
equipment for carbonization reactions in pilot scale experiments

After getting  permission from Party A to carry out the pilot scale experiments,
based on the research result of small-scale  tests,  Party B shall determine the
reacting conditions of the carbonization  reactor and key parameters of relevant
equipment for  carbonization  reactions,  and design the production  process for
pilot scale  experiments and relevant  equipment by cooperating  with the design
organization invited by Party A.

3. Pilot scale experiments

After  getting  permission  from  Party A about  the  stipulations  in the above
provision,  Party B  shall  provide  a  micro-mixing  reactor  for  pilot  scale
experiments. Party A shall provide the necessary equipment coordinating with the
micro-mixing  reactor as well as other  conditions  required  in the pilot scale
experiments, and carry out such tests under the instructions of Party B.



<PAGE>

Pilot scale experiments are designed to study how the gas-liquid phase ratio and
the  concentration of white lime milk will affect the size and appearance of the
obtained nano calcium  carbonate,  and check the stable operating  conditions of
equipment.  If there are  problems  affecting  the  technical  stability  of the
micro-mixing  reactor  during  the  pilot  scale  experiments,  Party B shall be
responsible for fixing them.

Party B shall submit a report of the pilot scale experiments.  Party A shall ask
experts to conduct  the check and  acceptance  of the result of the pilot  scale
experiments.

4. Commercial tests

After getting  permission from Party A to carry out the commercial tests,  based
on the research results of pilot scale experiments,  Party B shall determine the
reacting conditions of the micro-mixing  reactors and key parameters of relevant
equipment for  carbonization  reactions,  and design the production  process for
commercial  tests  and  relevant   equipment  by  cooperating  with  the  design
organization invited by Party A.

Commercial  tests are designed to study how the  gas-liquid  phase ratio and the
concentration  of white  lime milk will  affect the size and  appearance  of the
obtained nano calcium  carbonate,  and check the stable operating  conditions of
equipment.  If there are  problems  affecting  the  technical  stability  of the
micro-mixing  reactor during the pilot scale  experiments,  Party B shall assist
Party B to fix them.

Party A and Party B shall jointly submit the report of commercial tests. Party A
shall ask  experts  to  conduct  the check and  acceptance  of the result of the
commercial tests.

While working at the location of Party B, the board and lodging  expenses of the
staff of Party A shall be  covered  by Party A. If some staff of Party B need to
go  the  locale  of  Party  A  and  do  necessary  work  for  the  sake  of  the
implementation  of this project,  the travel expenses arising from this shall be
covered by Party A.

II. Required Technical Indicators and Parameters:

(I)   Required technical indicators and parameters for small-scale tests

1.    The granule diameter of the primary granule of the nano calcium  carbonate
      obtained by this technical  method shall be less than 60  nanometers.  The
      granules  whose  diameters are more than 60 nanometers  shall account less
      than 5% of the total mass.
