GONZALES, LA (July 8, 2008) – MIE Properties-LA has initiated construction on
Pelican Point Commerce Center, a new 32-acre business community in Gonzales, LA that, when
completed, will consist of four buildings offering more than 200,000 square feet of flex/research and
development space. The park is situated near the intersection of Interstate 10 and LA Highway 44 and
features more than 1500 feet of frontage along the interstate.

The development company’s initial building is a 37,440 square foot flex/research and
development project that offers 30-foot wide spaces, 16-foot ceiling heights, rear dock loading capabilities
and generous parking on the adjacent surface lot. It is expected to be delivered by this fall and, pending the
pace of leasing activity, MIE Properties-LA intends to break ground on succeeding buildings. Pelican
Point Commerce Center is positioned virtually equidistant from Baton Rouge and New Orleans.

“The local market continues to embrace our flex/office product category, which gives us
the continued confidence to move forward with this new speculative development,” explained Todd Pevey,
Vice President of MIE Properties-LA. “Leasing activity is strong throughout our Louisiana portfolio and
we are keeping pace with this continued construction momentum. Our research points to sustained demand
among tenants in a variety of industry sectors, and we feel it is important to have product in-hand to
quickly respond to these requirements,” he added.

“A growing number of companies seek corporate identification opportunities to increase
their visibility and marketing, and Pelican Point Commerce Center will offer an excellent venue with its
available frontage along Interstate 10,” Pevey said.

“MIE Properties-LA has forged an excellent reputation as a commercial real estate
developer and manager and it is encouraging to see this continuation of activity to support the demand in
our marketplace,” said Tommy Kurtz, President and CEO of the Ascension Economic Development
Corporation. “This additional office space translates to increased options for corporate relocations or
expansions, and a growing economic development environment,” he added.

MIE Properties-Louisiana has developed more than 350,000 square feet of commercial
and retail office space including Barringer Foreman Technology Park, Barringer Crossing I and II and
Main Street Pelican Point.

MIE Properties-Louisiana is an affiliate of St. John Properties, Inc., a Baltimore,
Maryland-headquartered company that owns and has developed more than 13 million square feet of flex,
warehouse, office and retail space in Maryland, Colorado, Delaware, Louisiana, Virginia and Wisconsin.
