In connection with this acquisition, we issued approximately 51,000 general partner units to our general partner, a wholly-owned subsidiary of Exterran Holdings. In May 2011, we sold, pursuant to a public underwritten offering, 5,134,175 common units representing limited partner interests in us, including 134,175 common units sold pursuant to an over-allotment option. The net proceeds from this offering were used (i) to repay approximately $64.8 million of borrowings outstanding under the revolving credit facility and (ii) for general partnership purposes, including to fund a portion of the consideration for the June 2011 Contract Operations Acquisition from Exterran Holdings. In connection with this sale and as permitted under the partnership agreement, we issued approximately 53,000 general partner units to our general partner in consideration of the continuation of its approximate 2.0% general partner interest in us.

We did not sell any common units in this offering and did not receive any proceeds from the sale of the common units by Exterran Holdings. In connection with our initial issuance of these units to Exterran Holdings, we agreed to pay certain costs relating to their future public sale. These costs have been recorded as a reduction to partners’ capital. As of June 30, 2011, Exterran Holdings owned 7,751,641 common units, 4,743,750 subordinated units and 757,722 general partner units, collectively representing a 35% interest in us.
