OGE Energy, ArcLight Capital Announce Equity Funding Agreement

OKLAHOMA CITY, Oct. 6 /PRNewswire-FirstCall/ -- OGE Energy Corp. (NYSE: OGE) and ArcLight Capital Partners LLC (ArcLight) today announced a transaction through which an ArcLight affiliate will acquire a 9.9 percent equity ownership stake in Enogex, OGE Energy's midstream natural gas pipeline subsidiary. As part of the transaction, OGE Energy will contribute its marketing business, OGE Energy Resources, Inc., to Enogex. ArcLight, a private equity firm based in Boston, has agreed to pay OGE $183 million for the equity ownership stake in Enogex.  The transaction, which is subject to customary closing conditions, is expected to be completed by November 1, 2010.

"We are pleased to announce this transaction, which creates value for OGE's shareowners today and in the future by improving our ability to capitalize on the significant growth opportunities for Enogex," said Pete Delaney, OGE Energy chairman, president and CEO. "Enogex's strong operating capabilities combined with the additional funding to be provided by ArcLight should accelerate the expansion of our natural gas midstream business."

The transaction will enable ArcLight to increase its ownership stake over time, by providing equity funding for capital expenditures associated with Enogex's business plan.

"The agreement will provide OGE Energy with additional equity funding flexibility that should enable OGE to fund ongoing capital expenditures at both businesses with the goal of improving our credit profile and increasing earnings," Delaney said

"As emerging natural gas resource plays continue to be developed, they are creating significant midstream infrastructure opportunities," said Robb Turner, Co-founder and Senior Partner of ArcLight Capital Partners. "Enogex has substantial organic growth opportunities around its strategically located mid-continent operations.  In addition, the company is well positioned as a leading midstream platform to grow into new regions and serve new customers. We have a long relationship with OGE's strong management team and believe together we can build an elite midstream business."  

OGE Energy will be represented on the Enogex Holdings LLC board by Delaney; Danny Harris, OGE senior vice president and COO; and Sean Trauschke, OGE vice president and CFO. Robb Turner will represent ArcLight on the board of directors. Enogex Holdings LLC will own 100 percent of Enogex LLC.
