                        Centerville Domes. In the event a new well is proposed
                        (other than a substitute well due to, but not limited to
                        mechanical difficulties) in the existing units or the
                        existing well is redrilled to a new bottomhole location,
                        Eagle will have the right to participate for its working
                        interest share.

                2.      Eagle will have the option to participate for its
                        working interest share in all leasehold acquisitions on
                        the subject domes subsequent to June 1, 1999.

                3.      Eagle will pay its allocated share of operating and
                        processing expenses and necessary facility enhancement
                        expenses. It is expressly understood that MEXP is not
                        selling any interest in any existing facilities or
                        pipelines.

                4.      The applicable existing Joint Venture Agreements and
                        Joint Operating Agreements will govern all operations on
                        the subject domes.

                5.      Eagle will have a restricted license to the proprietary
                        3-D seismic data covering Richmond, Grange, and Arm

                        office, but will not be granted a license on the 3-D
                        seismic data covering the Interdomal, Centerville,
                        Moselle, and Kola Domes and will be subject to the terms
                        and conditions under the applicable license agreements
                        owned by MEXP on these domes.

                6.      MEXP is currently discussing the sale of additional
                        interest in these prospects under the same terms and
                        conditions to the third parties. In the event MEXP sells
                        this program to a third party for less consideration,
                        Eagle will have the right to participate
                        proportionately for those same terms and condition.
