FOR IMMEDIATE RELEASE

Buildings to Serve as Noble Energy Headquarters

HOUSTON, TEXAS – Trammell Crow Company (TCC), in joint venture with Principal Real Estate Investors, announces the completion and opening of Noble Energy Center One, a 497,000 square foot office building located at 1001 Noble Energy Way in Houston’s Northwest office submarket. In addition, the joint venture has broken ground on a 4.7 acre site, Noble Energy Center Two, a 20-story, 470,000 square-foot build-to-suit office building located adjacent to Noble Energy Center One. Both buildings serve as global headquarters for Noble Energy (NYSE: NBL), a leading independent energy company engaged in worldwide oil and gas exploration and production.

The 10-story Noble Energy Center One underwent a significant capital renovation that began in January 2012, which included modifications to lobbies, elevators, landscaping, common areas, signage and other aspects of the building and parking garage. New features include a full service kitchen including a café, dining area and coffee bar,  fitness center, outdoor dining and meeting areas, and a state-of-the-art conference center. The project has also obtained LEED®Gold certification from the U.S. Green Building Council. Some of the building’s sustainable elements include low-flow plumbing fixtures, a water efficient irrigation system, and energy efficient lighting in both the building and the garage. Additionally, more than 75% of construction waste was recycled, salvaged or reused.

The architectural design concept includes unique stone feature displays on each floor, and custom wall coverings that represent aspects of the company’s core business – both domestic and international – in major circulation areas. In addition, the office design includes significant usage of interior glass so that occupants have generous access to daylight and views. Emphasis was placed on outfitting workrooms and conference rooms with collaborative technologies.

Concurrent with the completion of Noble Energy Center One, the development team has begun construction on Noble Energy Center Two. Noble Energy Center Two will feature an integrated eight-story parking garage, a Town Hall to serve corporate meetings, and an elevated sky bridge connecting to Noble Energy Center One. The building is pre-certified LEED® GOLD and the ownership is seeking ENERGY STAR certification. Noble Energy Center Two is scheduled to be complete by mid-2015.

The Noble Energy Center Two development team includes Austin Commercial as the general contractor and Kirksey as the project architect. JP Morgan and US Bank provided construction financing for the project.

The Noble Energy Center campus is located at the corner of State Highway 249 and Louetta, adjacent to The Vintage, a master-planned mixed-use community that features 537,000 square feet of retail/office space, over 1,600 upscale residences, two apartment communities, a 123-room hotel, Kelsey-Seybold Clinic, and a St. Luke’s regional hospital. It is also situated among an abundance of attractive wooded neighborhoods, golf courses, premier retail and restaurants and regional parks. Access is provided by way of Beltway 8, SH 249 and the planned Grand Parkway expansion, which will improve regional mobility throughout north and west Houston.
