Development Pipeline

ACC6, Ashburn, Virginia
We expect to develop ACC5 and ACC6 each in two phases on approximately 30.4 acres of land at the Ashburn Corporate Center in Loudoun County, Virginia. The ACC6 floor plan has not yet been determined, but we plan for the facility to be built in two phases and have an aggregate critical load of 31.2 MW.

ACC7, Ashburn, Virginia
ACC7 will be developed on approximately 10.4 acres of land at the Ashburn Corporate Center in Loudoun County, Virginia. Ground-up development of ACC7, which will be constructed in one phase, has not yet been scheduled. We anticipate that ACC7 will comprise 100,000 gross square feet and 50,000 raised square feet, with a critical load of 10.4 MW.

NJ1, Piscataway, New Jersey
NJ1 will be developed in two phases on approximately 38.1 acres of land in Piscataway, New Jersey, which is located less than 30 miles from New York City. It is presently anticipated that ground-up development of phase one of this development will be completed in 2009. We anticipate that NJ1 will comprise approximately 360,000 gross square feet and 171,200 raised square feet, and will have an aggregate critical load of 36.4 MW.

SC1 and SC2, Santa Clara, California
We have a contract to acquire 17.2 acres of land in Santa Clara, California, which, we believe, will support the development of two new data centers, which we refer to as SC1 and SC2 in this prospectus. We expect to complete our purchase of the Santa Clara land early in 2008. We anticipate that SC1 and SC2 will each be developed in two phases. It is presently anticipated that ground up development of Phase I of SC1 will be completed in 2009. Development of Phase II of SC1 and all of SC2 has not yet been scheduled. We anticipate that, upon completion, SC1 and SC2 will each comprise 360,000 gross square feet and 171,200 raised square feet, with an aggregate critical load of 36.4 MW.
