     Subject : Company Performance in The 2nd Quarter 2006
    
     To   : President
            The Stock Exchange of Thailand
    
     Rayong  Purifier  Public  Company   Limited  and its subsidiaries
      would like to clarify the decrease of  Baht  28.28 million
     in the Net Profit of the company after Tax in the 2nd Quarter 2006
      (2Q06) or down 18.9%, compared to the  2nd Quarter 2005 (2Q05).
      The main contributors  that caused  the decrease in the Net Profit
      from Baht  149.83million  in  2Q05 to Baht 121.55 million
      in 2Q06  can  be summarized as follows:-
     
       1.   Increase of Condensate Residue Supply
       In  2Q06, the company obtained an additional supply  of   feed  stock
     or  Condensate  Residue  (CR)  from   the   Aromatic  (Thailand)  PLC.
      This  helped  increase  the  production from 11.0 KBD in 2Q05 to 14.3 KBD
       in  2Q06,  by 3.3 KBD or 30% up.
     
       2.   Increase of Revenue and services
       The  revenue  of  the company in 2Q06  was  Baht  5,326  Million,
     increasing Baht 1,945 million or 58% from Baht  3,381million in 2Q05.
     This resulted from the   rising  oil  prices  in  the world market and
     increasing  sale volume of 27 million Liters or 14% up in 2Q06,
     compared  to 2Q05.
     
       3.   Gross Profit
       The Company earned Baht 278 million in gross profit  in  2Q06,
     decreasing Baht 14 million or 5% compared to Baht 292  million in  2Q05.
      This  was  due  to  the  lower  marketing margin in 2Q06 compared to
     the one in  2Q05,  when  the  controlled  diesel  price   policy
      was  promulgated.
    
       4.   Selling and Administration Expenditure
       In 2Q06, the company spent Baht 117 million in sale and
     administrative cost, increasing Baht 27 million or up   30%,
     compared to  Baht 90 million in 2Q05. This mainly  came from
     approximately Baht 8 million due to the   increase of sale volume
     in 2Q06, Baht 10 million from   retail segment expansion of
     PURE THAI ENERGY COMPANY   LIMITED (PTEC) and
      other subsidiary expenses.
     
       5.   Interest Expense
       The company paid  Baht 5 million or 125% more in 2Q06
      for the interest compared to 2Q05  as  a result of  rising interest rate
     and increase of interest expense  of VTN-P Petrochemical Joint Venture,
     subsidiary in   Vietnam.
    
       As a result, the net profit of the company decreased by
      Baht 28.28 million or 18.9%  in 2Q06 compared to 2Q05.
    
    
     Please be so informed.
