RPC signed Nang Nuan Crude Oil Contract with PTTEP

BackSep 07, 2005

To President The Stock Exchange of Thailand Rayong Purifier Public Co., Ltd. or RPC is pleased to inform that on September 6th, 2005, we signed the Purchasing Contract with PTTEP for 60,000 Barrels of crude oil from Nang Nuan oil field with total value of approx. 150 Million Baht. This will enable us to utilize 5KBD remaining refining capacity which will eventually increases our revenue and profit especially when the country s refining capacity is rather tight and all local refineries have almost been fully utilized. This is a good opportunity for us to secure more feedstock other than Condensate Residue (CR) from ATC. However, RPC is responsible to off-take all CR produced by ATC up to 12,600 Barrels per day as stated in the contract between RPC and ATC. Utilizing Nang Nuan Crude, Thailand s local feedstock, within the country not only maximizing the value of domestic resources locally but also helps decreasing the import of petroleum feedstock and products as well as saving foreign currency. At the same time, it increases the utilization of local refining capacity as a whole. Eventhough this is a spot (one time) contract as a test cargo, but if it produces good results, we will try to secure Nang Nuan Crude Oil on a long-term basis with PTTEP in due course. Please be so informed. Sincerely Yours, Ms.Siraporn Krishnakan Assistant to Managing Director Investor Relations / Managing Director Office Tel 0 2515-8671 E-mail:ir@rpcthai.com
