(1) - One line diagram

A draft of the one line diagram will be prepared.

D4 - Instrumentation

(1)- DCS and ESD conceptual specifications

Criteria to be developed into specifications for purchase will be prepared.

(2) - Functional design specifications

A description of the operation of each plant unit, with reference to the P&ID’s, and a list of the blocks will be prepared to enable the suppliers of the DCS and ESD systems to develop the software of both systems

D5 - Buildings, structural steel work and civil work

An outline of the main production building will be prepared, and the following items will be specified:

• Location of deposition reactors & converters with loads

• Overhead crane location and load

6. TIME SCHEDULE AND DEADLINES

All schedules and time are related on the project start. The project start is defined as the moment, when the down payment has been done by DAQO.

1 - Documentation of Know How and knowledge transfer

All documentation of the Know How described in Section 3 above will be delivered by the Contractor to the Customer within 4 (four) months after project start.

Note: The supply of the documentation will take place progressively in coordination with the preparation of the documentation of the Basic Engineering Package (as set forth in Section 4 and 5 above) as the availability of several elements of the basic engineering is necessary for the preparation of the documentation of the Know How. However, this process of preparation of the documentation will in no event extend the time period set forth above.

20

2 - Basic Engineering Package and Construction Services according to Sections 4 and 5

Note: The dates indicated below are depending on the availability of information from DAQO Group. However, the dates will be extended only if the Contractor has notified the Customer in writing about the information required by the Contractor and the time by which the Contractor requires such information; the dates will be extended only by the time by which information from the DAQO GROUP is delayed. Partial deliveries will be in accordance to the project development.
