AGREEMENT THIS AGREEMENT (this "Agreement") is entered into effective as of January 1, 2000, by and between FX Energy, Inc., a Nevada corporation, and its subsidiaries and affiliates through which it owns interests and carries out activities in Poland (collectively, "FX Energy"), and Apache Overseas, Inc.. a Delaware corporation, and its subsidiaries and affiliates through which it owns interests and carries out activities in Poland (collectively, "Apache"). Recitals A. Apache and FX Energy hold certain rights to explore for and exploit natural gas and oil in certain lands in the Republic of Poland and have been conducting exploration operations in Poland pursuant to various agreements. Apache and FX Energy jointly hold exploration rights covering approximately 11.5 million acres and options covering approximately 3.4 million acres controlled by Polski Gornictwo Naftowe i Gazownictwo S.A. ("POGC"). B. The strategic alliance of Apache and FX Energy has historically focused on an extensive exploration program. To date, Apache and FX Energy have jointly participated in the drilling of six wells, and Apache has covered all of FX Energy's drilling and completion costs for five of the six wells. Apache and FX Energy also entered into a Farmin Agreement with POGC with respect to POGC's Lachowice area. The Farmin Agreement was the first agreement of its kind executed by POGC with foreign entities. C. The close relationship that Apache and FX Energy have developed together. and with POGC will hopefully lead to an expanded program in the Republic of Poland that will include the acquisition of producing properties and the development and enhancement of proven properties within the Republic of Poland. Apache and FX Energy have been evaluating several opportunities, and, as a result of their analyses, executed a Letter of Intent with POGC that, among other things, establishes an exclusive negotiation period for a proposed transaction involving the acquisition of interests in the Koscian, Rensko, Obrzycko, Paproc East and Stezyca project areas (the "Zielona Gora transaction"). D. In light of these developments, Apache and FX Energy wish to modify certain provisions of their existing agreements and acknowledge certain additional agreements.

Future Well Carries. FX Energy hereby acknowledges and agrees that Apache has satisfied all of its seismic and drilling obligations to FX Energy in Poland other than as set forth in this paragraph. Apache will carry FX Energy in: (i) five wells located within the parties' Area of Mutual Interest and in which both Apache and FX Energy participate (the "Carried Wells"), and (ii) 350 kilometers of seismic in Blocks 410, 411, 412, 413, 414, 415, 430, 431, 432, 433, 452, and 453 (the 2 "Carpathian Blocks").

If a proposed Carried Well is a well required to satisfy a minimum work obligation of either the Lublin Blocks (defined below) or Carpathian Blocks, then FX Energy will be required to elect to be carried in that well. In the event a well is proposed outside of the Lublin or Carpathian Blocks, FX Energy will have the right to elect to be carried in such well, provided that Apache and FX Energy agree that such well is substantially equivalent to the wells previously drilled in Poland in terms of cost and depth. The commitments set forth in the previous paragraph are intended to supersede Apache's obligations to drill ten exploratory wells within certain specified time periods, as more fully described in the following Agreements: (i) Lublin Participation Agreement. Participation Agreement dated as of April 16, 1997 between Apache Overseas, Inc. and FX Energy, Inc. pertaining to the Lublin Area Concessions; (ii) Carpathian Participation Agreement. Participation Agreement dated as of February 27, 1998 between Apache Overseas, Inc. and FX Energy, Inc. pertaining to the Western Carpathian Concessions; and (iii) Global Agreement.
