Charlesbank Completes $220 Million Acquisition of Natural Gas Assets

BOSTON, MA--(Marketwire - August 7, 2009) - Charlesbank Capital Partners and Southcross Energy are pleased to announce the acquisition by Southcross of the South Texas, Mississippi and Alabama midstream natural gas assets of Crosstex Energy XTEX. The newly formed Southcross Energy is a natural gas transportation and processing company located in Dallas. Wells Fargo Securities arranged the financing for the transaction.

Southcross Energy is led by a seasoned team of industry executives. David Biegler, Chairman and Chief Executive Officer of Southcross, previously served as Chairman of Regency Gas Services, Vice Chairman of TXU and Chairman of ENSERCH. Mike Hunter, President, served as a Regency director and was formerly President of Lone Star Pipeline. Charlesbank first teamed with them to pursue midstream investment opportunities in 2002, a collaboration that culminated in the formation of Regency, a former Charlesbank portfolio company.

"I am delighted to partner with the Charlesbank team again, and to have their backing for what I am confident will be a strong company, with an excellent foundation," said Mr. Biegler. "The initial Southcross portfolio is an attractive mix of midstream assets that provide a wide range of essential services to customers and producers in historically rich natural gas regions."

The South Texas system consists of approximately 1,400 miles of intrastate gathering and transmission pipelines with throughput capacity of about 600,000 MMBtu/d and two processing facilities with a total processing capacity of approximately 195,000 MMBtu/d. The Mississippi and Alabama systems consist of approximately 780 miles of intrastate gathering and transmission pipelines with throughput capacity of about 185,000 MMBtu/d.

"After working for more than a year to identify the appropriate midstream energy opportunity, we are very pleased to complete this transaction," said Jon Biotti, Managing Director for Charlesbank. "With Southcross, we are able to acquire a stable set of assets with attractive underlying contracts alongside a talented and proven management team. We are certain that David Biegler's team will provide the strong operational focus and strategic leadership necessary to generate consistent cash flows and grow the asset base both organically and through acquisition."
