Liberty/Synterra & Iroko Pharmaceuticals Break Ground on a 56,412 Square Foot Sustainable Office Building at the Philadelphia Navy Yard

The Iroko Building is the fourth development Liberty/Synterra has started at The Navy Yard in 2011

PHILADELPHIA – September 7, 2011 – Liberty Property Trust(NYSE:LRY)/Synterra Partners broke ground on a 56,412 square foot Class A office headquarters building for Iroko Pharmaceuticals in the Philadelphia Navy Yard Corporate Center today.

“We were drawn to the Navy Yard initially because of the many advantages of being in Philadelphia and the vision of what the site could be,” said Osagie Imasogie, Senior Managing Partner, Phoenix IP Ventures, and Chairman, Iroko Pharmaceuticals. “The city is a wonderful place for the life sciences because of its highly educated workforce and research infrastructure. Our management team hails from around the world, and we choose to be in Philadelphia.”

Liberty is investing $15.4 million in the development of the project. When completed in the fourth quarter of 2012, the building will be the seventh sustainable commercial property Liberty has developed with Synterra Partners within the Navy Yard. Initially planned as an inventory office building, the Iroko Building was designed for Liberty/Synterra by DIGSAU, a Philadelphia-based design firm.

The four story office building was preleased to Iroko prior to site work commencing. This groundbreaking marks the fourth building Liberty/Synterra have commenced development on this year, development totaling in excess of 360,000 rentable square feet and representing more than $105 million in investment in high performance sustainable buildings.

“The Philadelphia Navy Yard’s vibrancy, coupled with Liberty/Synterra’s commitment to developing sustainable properties, has proven a very successful pairing,” said John Gattuso, Senior Vice President and Regional Director. “Even when one takes into account our inventory of new high performance flex buildings currently under construction, we are above 93% occupancy at the Navy Yard. It is clear the Philadelphia Navy Yard is attracting, keeping and growing a new generation of leading companies.”

Iroko established its first office in a small office suite at Liberty’s LEED Platinum One Crescent Drive at the Navy Yard Corporate Center in 2007. Growth came quickly, and by 2008 the company had expanded into the entire 19,600 square foot fourth floor. Today the company has 50 employees and expects significant growth by 2013.

Iroko has signed a long term lease at the new building, which has been designed to achieve LEED-CS Gold certification. Helping to keep energy costs down will be a BWAN (building wide area network) system designed by Liberty to track and manage energy use and efficiency in real time from a computer, phone or PDA.

Mayor Michael A. Nutter, who recently mentioned “a big development in The Navy Yard” at an economic development press conference, said, “It is companies such as Iroko that drive the recognition of Philadelphia as a center of excellence for life sciences, especially in light of the incredible resources and talent in the region. During this month of announcements, we are recognizing the valuable role that companies like Iroko play by creating jobs and making smart investments in our city. We are very pleased that Iroko, working with Liberty Property Trust, has chosen The Navy Yard for its home.”

Iroko’s expansion is partially fueled by the advancement of key product launches, according to John Vavricka, president and CEO of Iroko.

“Our NSAID (Non Steroidal Anti Inflamatory Drug) Development programs are proceeding well in Phase III,” said Iroko President and CEO John Vavricka. “Our Company is gearing up for major expansion of our sales and marketing efforts as we prepare for launch of our Nano reformulated NSAID products, so we are very excited about completion of this key facility.”
