19. Transactions Related to the Partnership

In March 2012, we sold to the Partnership contract operations customer service agreements with 39 customers and a fleet of 406 compressor units used to provide compression services under those agreements, comprising approximately 188,000 horsepower, or 5% (by then available horsepower) of our and the Partnership’s combined U.S. contract operations business. The assets sold also included 139 compressor units, comprising approximately 75,000 horsepower, that we previously leased to the Partnership, and a natural gas processing plant with a capacity of 10 million cubic feet per day used to provide processing services. Total consideration for the transaction was approximately $182.8 million, excluding transaction costs, and consisted of the Partnership’s payment of $77.4 million in cash and assumption of $105.4 million of our long-term debt.

In March 2012, the Partnership sold, pursuant to a public underwritten offering, 4,965,000 common units representing limited partner interests in the Partnership, including 465,000 common units sold pursuant to an over-allotment option. The Partnership used the $114.5 million of net proceeds from this offering to repay borrowings outstanding under its revolving credit facility. In connection with this sale and as permitted under the Partnership’s partnership agreement, the Partnership issued and sold to Exterran General Partner, L.P. (“GP”), our wholly-owned subsidiary and the Partnership’s general partner, approximately 101,000 general partner units in consideration of the continuation of GP’s approximate 2.0% general partner interest in the Partnership. The change in our ownership interest in the Partnership resulting from the sale of the common units resulted in adjustments to noncontrolling interest, accumulated other comprehensive income (loss), deferred income taxes and additional paid-in capital to reflect our new ownership percentage in the Partnership.

In June 2011, we sold to the Partnership contract operations customer service agreements with 34 customers and a fleet of 407 compressor units used to provide compression services under those agreements, comprising approximately 289,000 horsepower, or 8% (by then available horsepower) of our and the Partnership’s combined U.S. contract operations business (the “June 2011 Contract Operations Acquisition”). In addition, the assets sold included 207 compressor units, comprising approximately 98,000 horsepower, that we previously leased to the Partnership, and a natural gas processing plant with a capacity of 8 million cubic feet per day used to provide processing services.

In May 2011, the Partnership sold, pursuant to a public underwritten offering, 5,134,175 common units representing limited partner interests in the Partnership, including 134,175 common units sold pursuant to an over-allotment option.

In connection with this sale and as permitted under the Partnership’s partnership agreement, the Partnership issued and sold to GP approximately 53,000 general partner units in consideration of the continuation of GP’s approximate 2.0% general partner interest in the Partnership. The change in our ownership interest in the Partnership resulting from the sale of the common units resulted in adjustments to noncontrolling interest, accumulated other comprehensive income (loss), deferred income taxes and additional paid-in capital to reflect our new ownership percentage in the Partnership.

In March 2011, we sold, pursuant to a public underwritten offering, 5,914,466 common units representing limited partner interests in the Partnership, including 664,466 common units sold pursuant to an over-allotment option. We used the $162.2 million of net proceeds received from the sale of the common units to repay borrowings under our revolving credit facility and term loan. The change in our ownership interest in the Partnership resulting from the sale of the common units resulted in adjustments to noncontrolling interest, accumulated other comprehensive income (loss), deferred income taxes and additional paid-in capital to reflect our new ownership percentage in the Partnership.

In September 2010, we sold, pursuant to a public underwritten offering, 5,290,000 common units representing limited partner interests in the Partnership, including 690,000 common units sold pursuant to an over-allotment option. We used the $109.4 million of net proceeds received from the sale of the common units to repay borrowings under our revolving credit facility and term loan. The change in our ownership interest in the Partnership from the sale of the common units resulted in adjustments to noncontrolling interest, accumulated other comprehensive income (loss) and additional paid-in capital to reflect our new ownership percentage in the Partnership.

In August 2010, we sold to the Partnership contract operations customer service agreements with 43 customers and a fleet of approximately 580 compressor units used to provide compression services under those agreements, comprising approximately 255,000 horsepower, or approximately 6% (by then available horsepower) of our combined U.S. contract operations business. Total consideration for the transaction was approximately $214.0 million, excluding transaction costs. In connection with this acquisition, the Partnership issued to our wholly-owned subsidiaries approximately 8.2 million common units and approximately 167,000 general partner units.

Through our wholly-owned subsidiaries, we owned all of the subordinated units of the Partnership. As of each of June 30, 2011 and 2010, the Partnership met the requirements under its partnership agreement for early conversion of 1,581,250 of these subordinated units into common units. Accordingly, in each of August 2011 and 2010, 1,581,250 subordinated units converted into common units. As of September 30, 2011, the Partnership met the requirements under its partnership agreement for conversion of all remaining subordinated units into common units and therefore, the remaining 3,162,500 subordinated units converted into common units in November 2011.
