Mandatory Stocks of Liquid Fuels

Until April 7th 2007, the Group applied regulations concerning mandatory stocks of liquid fuels pursuant to Art. 19a.5 of the Polish State Reserves and Mandatory Fuel Stocks Act of May 30th 1996 (Dz.U. of 2003 No. 24, item 197, Dz.U. of 2004 No. 42, item 386, Dz.U. of 2005 No. 132, item 1110 and No. 143, item 1201). Pursuant to the above Act, producers and importers of liquid fuels are obliged to create mandatory stocks of liquid fuels, hereinafter referred to as “stocks,” based on the volume of liquid fuels produced or imported – from an EU member state or another state – in the previous year, taking into account the schedule for reaching the volume of liquid fuel stocks required at the end of a given year, in accordance with the appendix to the Regulation of the Minister of Economy on the schedule for the creation of liquid fuel stocks, dated December 19th 2005 (Dz.U. of 2005 No. 266, item 2240). This schedule specifies the path to reach in 2008, and subsequent years, the level of stocks corresponding to 76-day average internal fuel consumption at the end of the year. Thus, together with the existing economic reserves accounting for a 14-day consumption, the 90-day stocks required by the EU regulations will be reached. In each subsequent year, the required level of stocks should be increased by the stocks volume required for such number of days as is specified for each subsequent year in the Regulation of the Minister of Economy on the schedule for the creation of liquid fuel stocks, dated December 19th 2005.

Mandatory fuel stocks may be stored in the form of finished products, semi-finished products and crude oil. However, the total volume of stocks in the form of semi-finished products and crude oil (taking into account the capacity for processing crude oil into fuels) may not exceed the share of each type of fuel in the stocks, as stipulated in the Regulation of the Minister of Economy on the detailed procedure for the creation and determination of the volume of liquid fuel stocks, dated May 12th 2006 (Dz.U. of 2006 No. 92, item 642).

April 7th 2007 saw the introduction, by virtue of the Act on Stocks of Crude Oil, Petroleum Products and Natural Gas, as well as on the Rules to be Followed in the Event of a Threat to National Fuel Security or a Disruption on the Petroleum Market, dated February 16th 2007 (Dz.U. of 2007, No. 52, item 343, dated March 23rd 2007) of new regulations applicable to mandatory stocks, The mandatory stocks include crude oil, petroleum products (liquid fuels) and LPG. The Act defined the basis for calculation of the required amount of mandatory stocks as well as the entities subject to the requirement to increase mandatory stocks (73 days in 2007 and 76 days following 2008, excluding LPG).

Detailed rules are set forth in the following regulations of the Minister of Economy, effective as of May 25th 2007:

• Regulation concerning the detailed list of commodities and petroleum products included in the intervention stocks, dated April 24th 2007 (Dz. U. No. 81 item 546),
• Regulation concerning the detailed procedure for creation and maintenance of mandatory stocks of crude oil or fuels and determining their amount, dated April 24th 2007 (Dz. U. No. 81 item 547),
• Regulation concerning the register of producers and traders obliged to create and maintain mandatory stocks of crude oil or fuels, dated April 24th 2007 (Dz. U. No. 81 item 548),
• Regulation concerning the detailed procedure for the reduction of the amount of mandatory stocks of crude oil or fuels, dated April 24th 2007 (Dz. U. No. 81 item 549).

The gross value of mandatory stocks created on the basis of the above regulations is as follows:
