OFFICE DEVELOPMENT PIPELINE Houston’s development activity remained dormant in Q3 2010, with no new additions to the office buildings already under construction. The 2M square feet under construction are as follows: Indermuehle & Company’s 19,130-square-foot Sugar Creek Office Park (E. Fort Bend County 4 3 submarket) and Caldwell Companies’ 15,367-square-foot Webster Office Building (NASA/Clear Lake submarket). Two CBD office projects—Hines’ 972,474-square-foot Main Place (slated for delivery by February 2011) and Trammell Crow Company’s Hess Tower (formerly Discovery Tower, scheduled for completion by October 2010)—continue to be the sole high-profile buildings under construction at the end of the third quarter. Notably, both downtown projects began construction before the economic downturn of late 2008. Developers have ventured to introduce new product in high- 1 2 growth suburban markets, including a project in the East Fort Bend County submarket: Newland Communities’ 40,000-square-foot The Exchange at Telfair (expected by year-end 2010), which will be part of the planned mixed-use development for one of the area’s newest and most

5 successful master-planned communities of the same name. Other suburban projects include Greenwood Corporation’s 156,000-square-foot Chasewood Crossing II in the FM 1960-Highway 249 submarket (scheduled for completion in April 2011), as well as Black Forest Ventures’ 70,000-square-foot Black Forest Park, located in The Woodlands submarket and slated for delivery by November 2010. The German investment firm Black Forest Ventures (based in The Woodlands) recently made news with the acquisition of the Stanford Financial Center in the Galleria submarket, and is considered by industry leaders likely to continue expanding in Houston.
