Comcast Center Claims Its Place Atop the Philadelphia Skyline

Nation's Tallest Sustainable Skyscraper Rises 975 Feet into the
Clouds
PHILADELPHIA--(Business Wire)--
Amidst loud cheers and applause from more than 500 spectators,
Liberty Property Trust CEO Bill Hankowsky and Senior Vice President
John Gattuso, Comcast CEO Brian Roberts, Comcast Founder Ralph
Roberts, and design architect Robert A.M. Stern officially opened the
newest, tallest and greenest member of the Philadelphia skyline -
Comcast Center - at a reception this evening.

The 58 floor, glass-encased tower rises 975 feet into the air. It
surpasses One Liberty Place, developed by Liberty's predecessor
company, Rouse & Associates, as the city's (and in fact, the
Commonwealth of Pennsylvania's) tallest building. A high performance
green building, it has been designed to achieve LEED certification
from the US Green Building Council.

Comcast Center features 1.25 million square feet of Class A
office, restaurant and retail space; a dramatic eight-story winter
garden that includes a major art installation by sculptor Jonathan
Borofsky, a half acre public plaza with a seasonal cafe and unique
fountain installation, and "The Comcast Experience," a ground-breaking
hi-definition video wall standing 83.3' wide by 25.4' high, showcasing
a one-of-a kind intersection of media, technology and public art.

"Comcast Center, like Liberty Place, is not just a building, but a
great urban project that has transformed both the skyline and the
streetscape of an entire city block," said Hankowsky. "It breaks new
ground on several fronts - it creates a dynamic new experience for
commuters entering their city, it provides a stimulating, efficient
home that allows the state's largest corporation and most prominent
corporate citizen to continue to grow and contribute to the city's
financial vitality, and it serves as a beacon of sustainability in a
world striving for responsible environmental stewardship."

Comcast Corporation leases more than 90% of the building. The
"vertical campus" for the nation's leading provider of entertainment,
information and communications products and services, will house more
than 2,900 Comcast workers in a dozen departments, including the
company's corporate headquarters, Comcast Interactive Capital (the
company's venture capital arm), Comcast Interactive Media (the
company's Internet businesses), and all of the headquarters functions
for the company's Programming Division. Comcast University, the
company's highly regarded training and development program, is also in
residence.

"This is a defining moment in Comcast's history," said Roberts,
who dedicated the evening to his father, Comcast founder, Ralph
Roberts. "Our vision was to create a world class, exciting home and
classy, state-of-the-art space for Comcast employees in the City of
Philadelphia. We have been committed to this great city for over 40
years and this fantastic green building with great views in every
direction and on every floor is the result of our vision."

Other tenants in the complex include The Judge Group and Citizen's
Bank, which will occupy 50,000 square feet of office space and operate
a retail bank branch on the Plaza level. That ground level area also
features a Godiva Chocolatier retail location and Table 31 Steakhouse
Bistro, the newest restaurant from Philadelphia icons George Perrier
and Chris Scarduzio.

Comcast Center was designed by Robert A.M. Stern Architects, New
York, led by the firm's founder and senior partner Robert A.M. Stern.
Celebrating the opening of Comcast Center, Stern said, "We have
realized the dream of a great building that will house a great company
and that will be a meeting place for all Philadelphia as we move
forward into the 21st Century."

Kendall Heaton Associates of Houston, Texas, served as
architect-of-record for the building. Atelier Ten of London and New
York was the environmental design consultant.

An Investment in the Future of Philadelphia

The project included approximately $850 million of private
investment. According to a study prepared by Econsult, construction of
the project generated nearly $1.26 billion in one-time economic
activity, supporting over 5,400 jobs and almost $210 million in
earnings within the City of Philadelphia. Statewide, over $2 billion
in one-time total expenditures occurred, supporting over 17,000 jobs
and over $650 million in earnings. Additionally, over $12 million in
tax revenues were generated for the City of Philadelphia and over $44
million in tax revenues were generated for the Commonwealth during the
construction stage alone.

Each year after full occupancy, Econsult estimates that Comcast
Center will generate almost $1.16 billion in total expenditures
supporting over 6,500 jobs and almost $460 million in earnings within
the City of Philadelphia. In the Commonwealth, it is estimated almost
$1.65 billion in total expenditures supporting over 9,000 jobs and
almost $600 million in earnings each year.

Additionally, according to Econsult, Comcast alone - headquarters
and operations combined - generates total annual expenditures of $3.3
billion, 26,500 direct and indirect jobs, and earnings of $1.2 billion
in the 11-county Philadelphia region. This enormous economic impact
has doubled since 2004, while personal and corporate tax revenues to
state and local governments increased by 88 percent in the same period
to $240 million. Furthermore, between 2003 and 2007, Comcast made
significant financial and in-kind charitable contributions to the
Philadelphia region, totaling more than $1 billion during that period.

Construction of Comcast Center also included approximately $30
million worth of public improvements, including the dramatic new
gateway to Suburban Station, a renovation of the station's concourse
and a new public plaza at street level.

"One of the great stories behind this project is that a large
portion of this building was developed by minority, women, and
disabled-owned businesses and built by minority and women workers,"
said David L. Cohen, Executive Vice President, Comcast Corporation.
"Liberty and Comcast were committed to incorporate diversity into the
contracting and employment of this project and we are delighted, as
you can see first-hand, with this terrific result."

Minority/women/disabled-owned businesses (MWDB) were also key to
the success of the building of Comcast Center. In total, nearly $100
million worth of vendor contracts related to construction activity
were awarded to 73 MWDBs, which comprised 45% of the vendors on the
project. On a combined basis, more than 30 percent of the qualified
construction contracts entered into by Comcast and Liberty went to
MWBs and on the employment side, over 338,000 hours of work were
performed by minorities and women, representing 21% of all hours
worked on the project. In addition, approximately 40 percent of the
Comcast design work was awarded to minority and women owned businesses
and over 60 percent of the FF&E contracts were awarded to minority and
women-owned businesses.

"Every once in a long while a project comes along that can change
the tenor of a city, and Comcast Center is that project for
Philadelphia," said Mayor Michael Nutter. "Thousands of our citizens -
construction workers, plumbers, electricians, designers, masons,
artists, executives - look at Comcast Center and proudly tell their
friends and family 'That's my building.' And they are right - it is
their building and the building of every Philadelphian."

To further celebrate the opening, Comcast will donate a book in
the name of each Comcast worker to the Comcast Center to the Free
Library of Philadelphia. In total, the Comcast Foundation will donate
$125,000 to provide more than 2,900 new books to the Free Library to
help support education and literacy in the region.

Cornerstone of Sustainable Design

The tallest tower in Philadelphia has the distinction of being the
nation's tallest green office building. A high-performance green
building, Comcast Center is expected to achieve LEED certification
from the US Green Building Council. It boasts a multiplicity of
features designed to save energy and reduce environmental impact.

"This project employed everything we knew about sustainable design
and took it to a whole new level," said John Gattuso, Senior Vice
President of Urban and National Development for Liberty, who lead the
Comcast Center project team. "Every square foot of the building
encompasses some aspect of high performance design while the plaza,
art and fountains make it an outstanding public space."

The cutting edge sustainable design of Comcast Center can be found
in nearly every aspect of the building. Comcast Center uses 40% less
water than a typical office building, and fixtures will save more than
three million gallons of drinking water annually. Waterless urinals in
all restrooms will save 1.2 million gallons of urinal-water use every
year.

Shading on the plaza reduces the heat-island effect caused by
pavement by 70%. A glass curtain blocks 60% of heat while allowing 70%
of the sun's visible light, reducing energy used for air conditioning
while utilizing natural light to its fullest. An under-floor water
loop is used to cool the winter garden and 6th floor atrium floor
during the summer and warm it during the winter, saving energy.

Liberty diverted 77% of the waste from construction to salvaging
and recycling, keeping 20,000 tons of waste out of landfills. Glass,
aluminum cans, newsprint, white paper and cardboard are all recycled
through a program in the building. In addition, 80% of Comcast
Center's wood products are from forests with certification from the
Forestry Stewardship Council (FSC).

Astounding Clarity: "The Comcast Experience" Revealed

For months Philadelphians have wondered what the enormous shades
on the Lobby walls near the elevator were shielding. The answer was
revealed at the reception.

With a flick of a switch, Brian Roberts unveiled the centerpiece
of the lobby: the largest four-millimeter LED screen in the world.
Spanning 83.3 feet wide by 25.4 feet high, the 2,100 square foot video
wall brings spectacular original programming to visitors 18 hours a
day. Designed by BARCO, the wall displays thousands of unique hours of
programming, created solely for this use by The Niles Creative Group.

"Given the strong relationship between Comcast and Liberty and
Philadelphia, we wanted to make this special gift to the City in
connection with the construction and building of our new
headquarters," said Brian Roberts, commenting on The Comcast
Experience. "Philadelphia is known for its public art and The Comcast
Experience is a tribute to the spirit of creativity and technology
that is part of the fabric of this city."

Utilizing a technique called "3-Camera Panorama," which involves
placing three high-definition cameras side-by-side and filming
everything from spectacular nature footage to urban landscapes, a
seamless, wide-screen vista is created. This realistic imagery offers
10 million pixels of clarity - five times the resolution of
hi-definition TV- supplemented with computer-generated images of
amazingly realistic quality, producing a vivid virtual world."

The system that delivers the content to the screen has the ability
to make a pre-designed selection from a bank of hundreds of images.
This system combines elements of content into independent layers,
which are formatted based on the overall artistic direction for the
screen. The selection from the delivery system is random in nature, in
order to create an array of over-changing imagery.

For Tenants and Commuters Alike

Innovations such as The Comcast Experience can be seen and felt
throughout the building. Just walking onto the property at the street
level, visitors are welcomed by a half-acre landscaped public park
that features artistic fountains by Wet Design. Native landscaping by
the Olin Group creates a cool urban space during hot summer months.

Passing through energy-saving revolving doors brings them to the
Winter Garden lobby featuring three stories of glass on three sides.
There, the visitor encounters a father and son gazing up at the glass
canopy; a closer inspection shows them to be elements of the sculpture
Humanity in Motion by world-renowned artist and sculptor Jonathan
Borofsky. They are looking at nearly a dozen sculptures of people
walking their own paths - across beams suspended three stories high.

The project features another striking addition, just north of
Comcast Center: a new entrance lobby addition to historic Arch Street
Presbyterian Church, scheduled for completion on July 15.

A Dramatic Entrance: Suburban Station

When Liberty announced its intention to develop the building in
2001, a significant part of the vision was to give Philadelphia
commuters coming into Suburban Station a dramatic entrance that
reflected the dynamic urban environment they were entering. Commuters
will now have the opportunity to sample some of the best food and
retail the city has to offer before ascending the sweeping staircase
into the Winter Garden.

The Market at Comcast Center features some of the best-known icons
of Philadelphia and beyond. These include the delicious tastes of
Bucks County Coffee, DiBruno Bros., Jake & Max's Delicatessen,
LaScala's Italian American Home-Style To Go, Mexican Post, Frank's Old
Philly-Style Sandwiches, Sook Hee's Produce, Susanna Foo's Dumpling
Kitchen, Termini Bros, Tokyo Sushi & Catering and Under the "C"
(seafood.) The retail portion of the concourse includes higher-end
services and businesses including L'UOMO (custom Italian clothier),
Details, High Speed Cleaners, Gateway Newstands, and Govberg Jewelers.

The Market at Comcast Center is open Monday through Saturday. The
concourse itself, as an entrance and exit to the building, is open
year-round with 24-hour access.
