Comcast Corporation and the School District of Philadelphia Join Forces for Annual Community Day of Service

Over 1,650 Comcast employees and their families from the Philadelphia metro and surrounding areas will volunteer to improve local schools, parks, community centers, shelters and other organizations as part of Comcast's fifth annual company-wide day of service on October 1, 2005. Comcast Cares Day is one of the largest single-day corporate volunteer efforts in the United States. This year 30,000 employee volunteers are expected to work on projects at 300 locations in 32 States and the District of Columbia.

For one of the seven projects in the greater Philadelphia area, Comcast
Headquarters will partner with the School District of Philadelphia at Penn
Treaty Middle School which educates students in grades 5-8 from the
Kensington, North Philadelphia and Fishtown areas of the city. Together
Comcast and local school volunteers will refurbish the school's classrooms,
repaint exterior fencing, update the computer technology lab, conduct a
library book and school supply drive for students and teachers and organize
donations of athletic supplies and electronic equipment such as TVs and air
conditioners. The Mural Arts Program of Philadelphia will join the effort by
painting four murals inside the school.

"At Comcast, we have always believed in giving back to our communities,"
said Comcast Chairman and CEO, Brian L. Roberts. "This year's project at Penn
Treaty Middle School is really exciting for us because we are working with the
School District to improve education for some of Philadelphia's children, and
education is something Comcast is truly passionate about."

The day of service will being with a kickoff program at 9:00 am at Penn
Treaty Middle School (600 E. Thompson Street Philadelphia, PA 19125) with
participation from Mayor John Street, Ralph Roberts, Comcast Founder, Paul
Vallas, CEO of the School District of Philadelphia, Garry Maddox, former
Philadelphia Phillies outfielder and Philadelphia Phillies Hall of Famer and

"As we continue to make improvements across Philadelphia in our school
system, it is great to have local companies like Comcast contribute to the
effort," said James E. Nevels, chairman of the Philadelphia's School Reform
Commission. "Comcast continues to be a great corporate citizen to the entire
Greater Philadelphia region."

"I am thrilled that Comcast chose Penn Treaty Middle School as one of
their projects on Comcast Cares Day," said Paul Vallas, CEO of the School
District of Philadelphia. "By serving as good corporate citizens and investing
so much to improve conditions at Penn Treaty, Comcast is affecting young lives
in Philadelphia."

company's Comcast Cares program.
