Our customers have scaled back activity levels, as reflected byreduced capital expenditure levels and lower drilling rig counts, particularlyin North America.

We expect that business conditions will continue to bechallenging until natural gas supply and demand are more in balance.” Ernie L. Danner, Exterran Holdings` President and Chief Operating Officer, said,”As a result of our expectations for continued weakness in the North Americanatural gas market over the remainder of 2009 and our concern regarding ourVenezuelan operations, we are working diligently to ensure that our costs are inline with our business activity levels. Earlier this year, we disclosed ourplans to consolidate our fabrication operations in North America, which includethe closure of one major facility and the discontinuation of compressorfabrication activities at another. Today, we are announcing that we will reduceoperating and general and administrative costs, including headcount reductions,in all facets of our business. We believe, however, that the longer-term growthprospects for our company are strong given our leading market positions in ourfocus areas, and we intend to continue to execute our business strategiesincluding the expansion of our international contract operations businessthrough the successful execution of our backlog of new projects.” Exterran Partners, L.P.
