Constellation Energy Golf Classic, An Initiative of Mayo A. Shattuck, Tees Off Yesterday, September 11

Hunt Valley, Md. – September 12, 2006

The amount raised by the Constellation Energy Golf Classic (9/11 – 9/17) represents a mere fraction of what Constellation Energy gives to the community and other charitable organizations. The three areas in which Constellation Energy, led by Chairman/CEO Mayo Shattuck, supports are Corporative Giving, Volunteerism and Employee Giving. Last year, Constellation Energy gave approximately $10 million through its formal corporate programs, showing its strength in corporate philanthropy after only four years into Mr. Shattuck’s tenure.

Mayo A. Shattuck is more than the Chairman/CEO of Constellation Energy, a great golfer and the visionary behind the Constellation Energy Classic (9/11 – 9/17). First and foremost, Mr. Shattuck is a great leader—from the courts of Williams College, where he captained the varsity tennis team, to his current position, Mr. Shattuck also finds the time to serve in a variety of leadership capacities. Mr. Shattuck is currently a director on the boards of Gap, Inc. and Capital One Financial Corporation. He serves on the board of directors for several other organizations, including the Edison Electric Institute, Nuclear Energy Institute, and Institute of Nuclear Power Operations. Additional organizations to which Mr. Shattuck devotes his time and energy include the Board of Trustees of Johns Hopkins Medicine, the Advisory Council of Stanford Business School, the Board of Walters Art Museum, and as chairman of the Board of Visitors of the University of Maryland Baltimore County.

Under the tutelage of a leader of Mayo A. Shattuck’s caliber, Constellation Energy has compiled many industry awards. During 2004, only three short years after Mr. Shattuck joined the organization, the Edison Electric Institute awarded Baltimore Gas and Electric with its Emergency Assistance Award for its role in power restoration in Florida after the series of hurricanes that swept through the area. In that year, Constellation Energy was also awarded the Platts Energy Company of the Year Award for its leadership in the North American competitive electricity marketplace and impressive growth. These two achievements were in no small part attributable to Mayo A. Shattuck. The panel of international judges cited several factors in determining the winner. As the largest energy provider to commercial and industrial customers, Constellation Energy has achieved vigorous double digit growth over the course of Mr. Shattuck’s time with the company.
