2 Scope of Agreement2.1 The scope of this Agreement covers

a.

Design, manufacture, shop assembly, shop inspection and testing, and supply of Flame Scanner and Cooling Air Fan System Special Tools, Recommended Spares and consumable spares for the project.

b. c.

Remedy and defects therein; and Train the employers Representatives at Contractor /Subcontractors facilities.

2.2 Flame Scanner and Cooling Air Fan System and its accessories, Special Tools, Recommended Spares and Consumable Spares shall be utilized for the Project of 4x360 MW coal fired power plant in Ucchpinda, Janjgir Champa District, Chhattisgarh state, India. This has reference to the discussions had at Changchun on January 20th, 2011 and the subsequent emails exchanged between us and Forney Coporation and Beijing Eastern Transit Control Technology Co, Ltd., dated January 25th, February 14th, February 16th, March 25th, March 26th, April 1st, and April 7th 2011 on the subject. 2.3 The technical specifications of this Agreement shall be the minimum technical requirements, and do not cover all the technical details. The Contractor shall ensure all necessary technical specification to supply the latest industry standard products.

3 Project Related Information boilers to ensure the safe operation and forms a part of FSSS (Furnace Safety Supervision System). Based on the physical property of flame, the Scanner carries out a real-time detection on combustion situation. Once the flame combustion cannot meet the required conditions or flame is extinguished, the Scanner will give a signal as the judging condition for fault alarm to FSSS. According to the signal, the users can stop supplying the fuel into the boiler timely if the flame is extinguished, so that the boilers can be prevented from explosion resulting from accumulation of flammable materials in furnace.
