Superior Pipeline Company LLC (Superior), a wholly owned subsidiary of
Unit Corporation (NYSE: UNT), announced that it is in the process of

long term agreement with Range Resources Corporation (NYSE: RRC) as the
initial producer for the new plant. Start-up of the facility is expected
to occur during the second quarter of 2012.

“The construction of this new plant is consistent with Superior’s
strategic plan to build ‘greenfield’ gathering and processing assets in
the Mississippian trend,” stated Bob Parks, President of Superior. “We
are constructing this plant with the flexibility to accommodate future
expansions as we contract to receive additional gas volumes in northern
Oklahoma. This plant, along with our existing assets accessing the
Mississippian trend, will bring our overall processing capacity in the
region to over 100 MMcf per day.”
