(1) Universal Compression, Inc. ("UCI") owns a 98% LP interest in the Issuer. Universal Compression Holdings, Inc. ("UCH") owns 100% of UCI and thus may be deemed to beneficially own all of the reported securities. At the IPO closing, UCI will contribute certain equity interests to the Issuer in exchange for 825,000 common units representing limited partner interests and 6,325,000 subordinated units representing limited partner interests of the Issuer, reducing UCI's LP interest to 56.5%. Immediately following the IPO closing, UCI will contribute all of such common and subordinated units to its wholly-owned subsidiary UCI MLP LP LLC.
(2) Each subordinated unit will convert into one common unit at the end of the subordination period, which will end if the Issuer has earned and paid at least $1.40 on each outstanding unit for any three consecutive, non-overlapping four-quarter periods ending on or after September 30, 2011, but may end as soon as September 30, 2008, if the Issuer meets additional financial tests as described in the partnership agreement. The subordinated units have no expiration date.

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, See Instruction 6 for procedure.
