ITEM 5. OTHER EVENTS

On November 15, 2000, MarkWest Hydrocarbon, Inc. issued the following press
release:

                 MARKWEST HYDROCARBON, INC., ADDS SAN JUAN BASIN
                  PROPERTIES WITH SUBSTANTIAL UPSIDE POTENTIAL

     DENVER -- November 15, 2000 -- MarkWest Hydrocarbon, Inc. ("MarkWest")
(AMEX: MWP), announced today the acquisition of additional coal bed methane
properties and gathering systems in New Mexico's San Juan Basin for $5.625
million and will close in January 2001. The properties cover 4,800 acres and 40
producing gas wells containing 3.9 billion cubic feet (Bcf) of proved developed
reserves and 3.0 Bcf of proved undeveloped reserves, net to MarkWest. The
purchase also includes 11 miles of gathering pipelines. MarkWest will be the
operator of both the production and gathering systems, with initial production
of 1,200 thousand cubic feet per day (Mcfd) net to MarkWest.

     John Fox, President, said, "This expansion of our San Juan Basin assets is
consistent with our highly experienced technical and operating staff's ability
to add value by exploiting underperforming wells. We will utilize
state-of-the-art technologies on numerous recompletion and infill drilling
opportunities to significantly increase gas flow. The properties are highly
complementary to currently owned and operated fields in the Colorado portion of
the basin and afford opportunities for expansion of a low-pressure gathering
system and compression facilities improvement. We also see a substantial
pipeline and compression services opportunity surrounding our property."

     Fox went on to say, "This new addition will increase our year-end 2001 exit
rate of production to approximately 6,800 Mcfd from a previously expected 4,500
Mcfd rate. This acquisition will increase cash operating income for the Rocky
Mountain Business Unit from $2.5 million to $4 million in 2001, with further
increases in 2002. The unit's capital expenditures will be increased from $1.5
million to $3.5 million to implement this program."
