Deregistration of Unsold Shares of Common Stock
-----------------------------------------------
Pursuant to Post-Effective Amendment No. 1 ("Post-Effective Amendment No.
1") to the Company's Registration Statement on Form S-1 (File No. 333-26233)
(the "Registration Statement"), MarkWest Hydrocarbon, Inc. (the "Company")
deregistered the remaining shares of the Company's Common Stock which were
registered with the Securities and Exchange Commission pursuant to the
Registration Statement and which were not sold pursuant to such Registration
Statement. As disclosed in such Registration Statement, the Company agreed to
file and maintain a shelf registration statement relating to the Shares
registered thereby in order to permit certain stockholders to resell such shares
from time to time during a period of at least 60 days from April 30, 1997, the
date of the Prospectus. Such shares were deregistered because said 60-day
period, as extended in the sole discretion of the Company, had elapsed. Post-
Effective Amendment No. 1 incorrectly indicated that the number of unsold shares
deregistered as a result of Post-Effective Amendment No. 1 was 45,703. The
correct number of unsold shares to be deregistered as a result of Post-Effective
Amendment No. 1 was 46,703. Accordingly, to the extent that any shares
registered by the Registration Statement were not deregistered as a result of
Post-Effective Amendment No. 1, the Company hereby deregisters such shares
pursuant to this Post-Effective Amendment No. 2.
