Revised 20/20 Schedules

Attached is a redlined copy of the revised schedules to the Purchase and Sale
Agreements. Also attached, for the sake of completeness, are the supplements
to the schedules. The supplements are the same as prior versions, except for
some changes to the title defects schedules for the Maverick, Box Draw, and
Caballo systems.

I attempted to redline the schedules for the title defects, but it redlined
the whole list. The only change of substance added was a new Wyoming DOT
road crossing permit to Maverick. Also taken off were references to the
documents that have been prepared and sent to Gillette (that information was
contained in brackets and began "[See Attached ....]. That information was
for the right of way agents in Gillette so that they knew what documents had
been prepared for them. Please let me know if you have any questions.
