Exelon to Launch Exchange Offer for NRG Energy, Inc.

CHICAGO (Nov. 11, 2008) — Exelon Corporation (NYSE:EXC) announced today that it will launch an exchange offer on Wednesday, Nov. 12 for all of the outstanding shares of NRG Energy, Inc. common stock at a fixed exchange ratio of 0.485 Exelon shares for each NRG share.

“While we would have greatly preferred to enter into direct negotiations with NRG’s board and management, their decision to reject our proposal, without any discussion with us as to the merits or structure of our proposal, has left us with no choice but to bring the offer directly to the NRG shareholders,” said John W. Rowe, Exelon chairman and CEO. “Based on the positive investor response to our proposal, we expect our exchange offer will garner strong support from NRG shareholders, who will not only receive a significant premium for their shares but will also participate in the future growth of the nation’s largest and most diversified power company as new shareholders of a combined Exelon and NRG.”

In a written response to NRG’s Nov. 9 letter rejecting Exelon’s offer, Rowe outlined the compelling strategic, operational and financial value drivers of a combined Exelon-NRG. A copy of Rowe’s letter to NRG is reprinted below.

Exelon also announced today that it has filed a lawsuit in the Delaware Chancery Court against NRG and its directors alleging, among other things, a breach of fiduciary duty by NRG’s directors for various reasons, including the failure of the NRG directors to give appropriate consideration to, and take appropriate action on, the proposal announced by Exelon on Oct. 19. The action seeks relief requiring the NRG board to exempt Exelon’s exchange offer from the Delaware business combination statute, and enjoining the board from taking any actions to frustrate the exchange offer.

“Judicial relief is necessary to ensure that the NRG Board complies with its fiduciary duty to provide the NRG stockholders with the opportunity to decide whether to take advantage of transactions offering them substantial premiums,” the lawsuit states.

Exelon’s Letter to NRG

The full text of Exelon’s Nov. 11 letter to Howard Cosgrove, chairman of the board of NRG and David Crane, president and CEO of NRG, sent in response to their Nov. 9 letter, is reprinted below.

November 11, 2008

Mr. Howard Cosgrove,

Chairman of the Board

Mr. David Crane,

President and Chief Executive Officer

NRG Energy, Inc.

211 Carnegie Center

Princeton, NJ 08540

Dear Howard and David:

Our board was disappointed by your rejection of our proposal. We had hoped to have an opportunity for a constructive conversation prior to your decision. We continue to believe that a combination of our two companies will provide superior value to our respective shareholders.

We strongly disagree with the assertions in your November 9 letter. We think it is important to comment on the following principal points:

Clear Strategic Rationale for the Merger

The combination of NRG and Exelon will create substantially more value for both companies’ shareholders than either company can realize alone. It will create a significantly stronger enterprise on both operational and financial levels. The combined company will be the preeminent low-cost producer of power in the industry, operating in the most attractive markets, and providing earnings and cash flow accretion to shareholders of both Exelon and NRG. In addition, the combined company’s balance sheet will benefit from our investment grade credit rating that will provide greater flexibility for growth and hedging while ultimately reducing the cost of capital.

Strong Value Proposition to NRG Shareholders

Exelon’s proposal provides NRG shareholders an immediate premium and affords them the opportunity to continue to participate in the future value-creating prospects of the combined entity. Moreover, it does so without any tax leakage. With the largest market capitalization in the industry and Exelon’s exceptional record of growth over the past seven years, NRG shareholders will benefit from a more liquid, dividend-paying and less risky investment relative to NRG stand-alone. Additionally, the combined company offers greater potential for stock appreciation at a faster pace than NRG could achieve on a stand-alone basis.

Your analysis overlooks the less risky nature of Exelon’s cash flows. It also ignores the fact that value is driven more by future growth prospects than by historical performance. Moreover, Exelon’s cash flow is stronger and growing faster than NRG’s.

Financing Is Not an Obstacle

A negotiated business combination can be structured in a way that does not trigger the change of control provisions for NRG’s senior notes, which will reduce refinancing requirements to $4 billion or less. We can secure committed financing for that amount at the appropriate time. Reflecting our confidence in that regard, the transaction will not be subject to a financing condition.

In sum, a combination of Exelon and NRG will create superior value for all shareholders. While we would like the opportunity to meet directly with you to discuss the merits of these points, the tenor of your response has led us to conclude that we must take our proposal directly to your shareholders. We are hopeful that a transaction will ultimately be negotiated with the current NRG board. Failing that, we are fully prepared to negotiate with the new board following the 2009 NRG annual meeting of shareholders.

Sincerely,

John W. Rowe

Chairman and Chief Executive Officer
