Technical correction to the comment on the financial results by business segment

Technical correction to the comment on the financial results by business segment, regarding the classification of internal revenues, depreciation and amortization. The change does not affect the result and segment results of PKN ORLEN.

The Management Board of Polski Koncern Naftowy ORLEN S.A. (“PKN ORLEN”) informs that, in the attachment to the Regulatory announcement no 50/2006 released on August 11th 2006, concerning the financial data for Q2 2006 and the first two quarters of 2006, under segments with commentary, an editorial error appeared. The originally presented information concerning the value of depreciation and amortization in some business segments, and the value of revenue transfers between the refining and retail segment differ from that actually classified. The data re-editing does not influence the previously presented operating result of PKN ORLEN but it is only an editorial correction of data reported for some business segments.

In the attachment to the Regulatory announcement no 50/2006, as of August 11th 2006:

1. The chart „PKN ORLEN S.A. KEY CONSOLIDATED FINANCIAL DATA BY BUSINESS SEGMENT for the period of 6 and 3 months ended 30 June 2006 and 30 June 2005 (PLN ‘000)”on page 15: in the section of the chart concerning depreciation and amortization in the petrochemicals segment for the 6 months ended 30 June 2006 The figure 204,487 should be: 367,456.

5. In the footnote to the chart „ Refinery (Production + Wholesale)” on page 3:
The text: The revenue includes the following transfers to retail:: 6 months 2006 – PLN 1 083 057 thousand, 3 months 2006 – PLN 114 194 thousand, 6 months 2005 – PLN 1 621 591 thousand, 3 months 2005 – PLN 913 101 thousand.

Correction of the above mentioned numbers influences neither the originally presented total depreciation and amortization value in the various PKN ORLEN business segments in the analyzed periods nor the originally presented value for the operating result in the Production and Wholesale segment as well as in the Retail segment.
