-- Plan to pursue Initial Public Offering of Partnership

CenterPoint Energy, Inc. (NYSE: CNP), OGE Energy Corp. (NYSE: OGE) and ArcLight Capital Partners, LLC (ArcLight) announced today that they have entered into an agreement to form a master limited partnership that will include CenterPoint Energy’s interstate pipelines and field services businesses and the midstream business of Enogex LLC, owned jointly by subsidiaries of OGE and Arclight. The partnership will be managed by a general partner whose governance will be shared by CenterPoint Energy and OGE on a 50/50 basis.

Creation of a New Leading Midstream Company

The new partnership will own and operate 8,400 miles of interstate pipelines with nearly 9 billion cubic feet of transport capacity and nearly 2,300 miles of intrastate pipelines. It will also have more than 11,000 miles of gathering lines, which in 2012 moved nearly 4 billion cubic feet of natural gas per day. Additionally, it will have more than 90 billion cubic feet of natural gas storage capacity and 11 major processing plants with nearly 2 billion cubic feet per day of inlet capacity.

The partnership will benefit from:

-- Enhanced scale

-- Geographic diversification, with operations in major natural gas and liquids-rich producing areas of Oklahoma, Texas, Arkansas and Louisiana

-- Significant asset positions in a broad range of basins, including the Granite Wash, Tonkawa, Mississippi Lime, Cana Woodford, Haynesville, Fayetteville, Barnett and Woodford plays

-- Enhanced supply and market access

-- Meaningful operating and commercial synergies

-- Stable and predictable cash flows from a balanced and diversified portfolio of assets

-- Independent access to capital

“We are very excited about creating a substantial, growth-oriented midstream company,” said David M. McClanahan, president and chief executive officer of CenterPoint Energy. “This new company will be a significant participant in the rapidly growing midstream market. With enhanced scale, broader geographic reach and expanded capabilities, the partnership will be able to compete in ways that neither we nor Enogex could do as separate companies.”

“The stronger financial and operational capabilities of the new partnership should allow us to realize the full potential of these assets," said Pete Delaney, Chairman and CEO of OGE Energy. “We believe all of our shareowners will benefit from the creation of this partnership as a stronger competitor that we expect to be valued on a public MLP basis."

“The partnership provides a very attractive investment opportunity supporting the strong growth of the US natural gas and liquids infrastructure build out,” said Robb Turner, senior partner of ArcLight. “The combination of growth opportunities, long-term customer relationships and stable assets across many of the premier on-shore US basins complement each other well and provide a compelling investment thesis.”

The partnership’s leadership team will be announced after regulatory approvals are received. Prior to closing both companies will continue to operate independently, and teams of personnel from both companies will develop an integration plan that can be implemented once the transaction has closed.

Transaction Terms and Other Details

The companies expect to close the formation of the partnership in the second or third quarter of 2013, following receipt of customary regulatory approvals and certain third-party consents. Under the terms of the agreement, the new partnership will seek to arrange a new $1.4 billion credit facility as well as a $1.05 billion term loan. The transaction has been approved by the board of directors of CenterPoint Energy and OGE Energy, as well as ArcLight.

Subject to certain adjustments at closing, CenterPoint Energy, OGE Energy and ArcLight will have 59 percent, 28 percent and 13 percent limited partner interest in the partnership, respectively. CenterPoint Energy and OGE Energy will hold 40 percent and 60 percent interests, respectively, in the incentive distribution rights of the general partner.

Pursuant to a registration rights agreement to be signed upon the closing of the transaction, OGE and CenterPoint Energy will agree to initiate the process for the sale of equity interests in the partnership in an initial public offering (IPO). In consultation with ArcLight, OGE, CenterPoint Energy and the partnership will determine the financial and other terms of any such IPO. The execution of any IPO is subject to market conditions and the parties can give no assurance that such an IPO will in fact take place.
