Investor Presentation

December 19, 2005

Safe Harbor Language

This presentation includes “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. These forward-looking statements include, for example, statements regarding benefits of the proposed merger, the likelihood and timing of closing of the proposed merger, integration plans, expected synergies, anticipated future financial and operating performance and results, including estimates for growth. Any statements that express, or involve discussions as to expectations, beliefs, plans, objectives, assumptions or future events or performance (often, but not always, through the use of words or phrases such as “will likely result,” “are expected to,” “will continue,” “is anticipated,” “believe,” “could,” “estimated,” “may,” “plan,” “potential,” “projection,” “target,” “outlook”) are not statements of historical facts and may be forward-looking. There are a number of risks and uncertainties that could cause actual results to differ materially from the forward-looking statements made herein. These risks and uncertainties include, for example, the ability to obtain governmental approvals of the transaction on the proposed terms and schedule; the failure of FPL Group, Inc. (FPL Group) or Constellation Energy Group, Inc. (Constellation Energy) stockholders to approve the transaction; the risk that the businesses will not be integrated successfully or that anticipated synergies will not be achieved or will take longer to achieve than expected; disruption from the transaction making it more difficult to maintain relationships with customers, employees, suppliers or governmental entities; unexpected transaction costs or liabilities; economic conditions; and other specific factors discussed in documents filed with the Securities and Exchange Commission by both FPL Group and Constellation Energy. These risks, as well as other risks associated with the merger, will be more fully discussed in the joint proxy statement/prospectus that will be included in the Registration Statement on Form S-4 that Constellation Energy will file with the SEC in connection with the proposed merger. Readers are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this presentation. Neither Constellation Energy nor FPL Group undertakes any obligation to publicly release any revision to its forward-looking statements to reflect events or circumstances after the date of this presentation.

Use Of Non-GAAP Financial Measures

It is important to recognize that in certain instances in this presentation we have adjusted actual financial results, prepared in accordance with generally accepted accounting principles (GAAP), for certain items, including special items (which are defined as items not related to the ongoing, underlying business or which distort comparability of results) and certain economic, non-qualifying hedges. We have also provided earnings estimates in terms of adjusted earnings, excluding special items and certain economic, non-qualifying hedges. We believe that the resulting adjusted, non-GAAP information provides a picture of results that is comparable among periods since it excludes the impact of items, the size and nature of which can make period to period comparisons difficult and potentially confusing. However, investors should note that non-GAAP measures involve judgments by management. We note that such information is not in accordance with GAAP and should not be viewed as an alternative to GAAP information. A reconciliation of adjusted information to GAAP is included either on the slide where the information is appears or in the appendix to this presentation. These slides are only intended to be reviewed in conjunction with the oral presentation to which they relate.

Non-Solicitation

This communication is not a solicitation of a proxy from any security holder of FPL Group or Constellation Energy. Constellation Energy intends to file with the Securities and Exchange Commission a registration statement that will include a joint proxy statement/prospectus of Constellation Energy and FPL Group and other relevant documents to be mailed to security holders in connection with the proposed transaction. WE URGE INVESTORS TO READ THE JOINT PROXY STATEMENT/PROSPECTUS AND ANY OTHER RELEVANT DOCUMENTS WHEN THEY BECOME AVAILABLE, BECAUSE THEY WILL CONTAIN IMPORTANT INFORMATION ABOUT FPL GROUP, CONSTELLATION ENERGY, AND THE PROPOSED TRANSACTION. A definitive proxy statement will be sent to security holders of FPL Group and Constellation Energy seeking approval of the proposed transaction. Investors and security holders will be able to obtain these materials (when they are available) and other documents filed with the SEC free of charge at the SEC’s website, www.sec.gov. In addition, a copy of the joint proxy statement/prospectus (when it becomes available) may be obtained free of charge from Constellation Energy, Shareholder Services, 750 E. Pratt Street, Baltimore, MD 21201, or from FPL Group, Shareholder Services, P.O. Box 14000, 700 Universe Blvd., Juno Beach, Florida 33408-0420.

This communication shall not constitute an offer to sell or the solicitation of an offer to buy any securities, nor shall there be any sale of securities in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of such jurisdiction. No offering of securities shall be made except by means of a prospectus meeting the requirements of Section 10 of the Securities Act of 1933, as amended.

FPL Group, Constellation Energy, and their respective directors and executive officers of FPL Group and Constellation Energy and other persons may be deemed to be participants in the solicitation of proxies in respect of the proposed transaction. Information regarding FPL Group’s directors and executive officers is available in its proxy statement filed with the SEC by FPL Group on April 5, 2005, and information regarding Constellation Energy’s directors and executive officers is available in its proxy statement filed with the SEC by Constellation Energy on April 13, 2005.

Brian Ferguson, a director of FPL Group elected since the the date of the filing of the 2005 definitive proxy statement, can be found in the Company’s filing on Form 10-Q dated August 4, 2005. Other information regarding the participants in the proxy solicitation and a description of their direct and indirect interests, by security holdings or otherwise, will be contained in the joint proxy statement/prospectus and other relevant materials to be filed with the SEC when they become available.

* We are unable to reconcile our estimated future adjusted earnings to GAAP earnings because we do not predict the future impact of special items and economic, non-qualifying hedges due to the difficulty of doing so. The impact of special items and economic, non-qualifying hedges could be material to our operating results computed in accordance with GAAP.
