      ----------------------------------------------------------------------

2.3   In order to ensure party B's normal operation, recovery of investment and
      reasonable profit, both party A and B agree to the following matters:

      2.3.1 Party A shall control the discharge standard for industrial sewage
            discharging into municipal sewage network. If the plant's discharge
            of sewage beyond the standard causes the sewage inlet water quality
            of the project exceeds the designed standard, which causes the
            sewage treatment cannot meet the standard, party A shall pay party B
            sewage treatment fee as per normal rate and at the same time party B
            shall make report to party A within 24 hours. Party A shall
            investigate the reason for exceeding the standard within 24 hours
            after receiving the report and take relevant measures.

      2.3.2 Party A agrees that party B conducts annual planned shutdown
            maintenance during the term of operation. If the sewage treatment
            plant is planned to make maintenance, party B shall make application
            to local environmental authority 15 days in advance and give a
            written notice to party B. Only the approval of the environmental
            authority is got can party B conduct maintenance. During
            maintenance, party A shall not investigate party B's responsibility
            for outlet water exceeding the standard. Maintenance is allowed once
            every year, and the duration of maintenance shall not exceed 20
            days.

                                       2
<PAGE>

     2.3.3 Party A agrees that party B has suitable debugging time after
           maintenance (party B shall apply to party A for it before
           maintenance). Party B's debugging period for conformity of standard
           shall not exceed 28 days.

2.4   In water treatment, due to the fact that when the microorganisms are under
      8iae entigrade, the treatment efficiency decreases greatly, so when the
      temperature of inlet water of the sewage treatment plant is lower than
      7iae entigrade, if some outlet water indexes cannot meet the outlet water
      standard stated in table 2.1 hereof, the case is deemed as caused by
      natural reason and party B shall not be liable for it, and party A still
      deems the water as in conformity to the standard and pay sewage treatment
      fee to party B pursuant to the designed water volume and the payment
      standard stated in Article 2.6 and pay sewage discharge fee for exceeding
      the standard incurred thereby to environmental authority.

2.5   To ensure the smooth implementation of the project, party A shall
      coordinate the participation of banks at the project's location. Specific
      method is as this: After conclusion of the Contract, based on the project,
      party B shall set up a wholly owned specialized sewage treatment company
      at the local place as its economic entity to implement the project and
      shall be responsible for the project's preparation, construction and
      operation with full power. At the same time, party A is responsible for
      introducing a local bank to party B for party B to make negotiation about
      specific cooperation with it. Party B pledges its operation and fee
      collection right of the sewage treatment plant under the Contract to the
      bank to apply to it for loan for the project; proportion of the loan is
      45% of the total investment of the Contract, and this loan shall be only
      used for construction and purchase of part of equipment of the project
      under the supervision of the bank. 55% capital owned by party B will be
      directly invested into the project for technology, design and equipment
      purchase. To ensure that the project can be completed safely, on time and
      with stated quality, party B shall effect insurance with an insurance
      company or seek a bonding company to make guarantee. To ensure recovery of
      the bank loan, the sewage treatment fee received by party A shall be
      deposited into the bank's special account and shall be settled under the
      supervision of the bank; party B shall also open a special account as
      settlement account. Party B shall regard the sewage treatment fee paid by
      party A as source of fund for repayment of the bank loan, and after
      transferring the sewage treatment fee received to the settlement account
      every month, party B shall repay the bank loan as per proportion agreed to
      by party B and the bank.

2.6   After Handan Fengfeng Mining Area Sewage Treatment Plant is constructed,
      the date on which the acceptance inspection of the project's debugging on
      completion is passed shall be the starting date of the term of operation
      of party B. From the starting date, the term of operation of party B is 22
      years. During the term of operation, party B shall make management and
      operation with full power to recover its investment and obtain profit from
      operation. During the term of operation of party B, party A is responsible
      for depositing the sewage treatment fee received by the local government
      into the special account of the bank stated in Article 2.5 hereof as the
      source of fund to pay sewage treatment fee to party B and repay party B's
      bank loan. If party B cannot meet the outlet water standard stated in
      table 2.1 hereof, party A can refuse to pay the sewage treatment fee for
      this part of sewage. Settlement method is: Party A pays sewage treatment
      fee for the previous month to party B the 5th day every month. The fee
      rate for party A to pay sewage treatment fee excluding tax is (if party B
      needs to pay tax, party A shall supplement the same to party B in full
      amount): [omitted].

                                       3
<PAGE>

2.7   Party A ensures that it will pay the sewage treatment fee in full amount
      to party B as scheduled every month for party B to recover its investment
      and make reasonable earnings. If the sewage treatment fee received by
      party A is not enough to pay the sewage treatment fee to party B, party A
      shall be responsible for raising fund from other channels, and party A's
      government shall issue a letter of guarantee for payment in full amount to
      ensure the payment of sewage treatment fee in full amount to party B on
      time. After expiration of the term of operation, Party B shall hand over
      the sewage treatment plant that is sound and that can operate safely and
      normally to party A, upon which, party B's operation and management right
      is finished.

2.8   The calculation method for party A to pay sewage treatment fee to party B:
      In constructing the sewage treatment plant, party B shall conduct design
      and construction work according to the sewage treatment volume determined
      by party A and install water meter at the back of water inlet pump of the
      sewage treatment plant and party A will regard the data on the meter as
      the basis for calculating the sewage treatment fee that should be paid to
      party B every month. If party A cannot supply the designed rated volume of
      sewage to party B for treatment, party A shall pay sewage treatment fee as
      per the designed rated volume to party B. Sewage treatment fee for the
      part in excess of the designed rated volume shall be paid as per the cost,
      i.e. [omitted].

2.9   Meter reading time for the sewage treatment volume shall be 16:00, the
      28th day of every month. Party B shall write the reading on the meter by
      the end of 16:00, the 28th day of every month on the meter reading
      settlement sheet, and party A shall, before 12:00 PM of the same day, send
      personnel to check the sheet and make calculation and sign on it, which is
      in triplicates, one copy of which for party A and B each and one copy for
      the bank. The bank regards the sheet as the basis for transfer of
      accounts, and shall directly transfer the money in party A's special
      account to party B's special account as per the amount on the sheet
      without party A's confirmation. If party A fails to send personnel to
      check the sheet and make calculation at the 28th day, after 12 o'clock
      that night party A shall be deemed as has approved the settlement sheet,
      and when the bank directly makes transfer of account according to party
      B's meter reading settlement sheet, party B shall have no objection.

2.10  During the term of operation, if the state's currency depreciates, the
      sewage treatment fee that should be paid by party A to party B shall be
      adjusted according to the depreciation coefficient published by the state.
      If there is inflation and rising prices, party A shall adjust the unit
      price for sewage treatment fee according to the price index published by
      the state and pay the supplemented fee to party B. If inflation and
      fluctuation of price index in accumulation does not exceed 15% on the base
      of the year in which the contract is signed, party A needs not to adjust
      the unit price; if it exceeds 15%, party A shall adjust the unit price for
      the sewage treatment fee that should be paid to party B according to the
      coefficient of the part in excess. And likewise, if price index falls by
      15%, party A shall also adjust the settlement unit price accordingly.
