HOUSTON-Parkway Properties Inc. has added two new tenants to its class A office building at 1401 Enclave Pkwy. in the Energy Corridor. Chemical Market Associates Inc. signed a 10-year lease for 26,000 square feet, and Callon Petroleum Co. signed a 10-year new lease for 12,000 square feet.

The new tenants will backfill a large portion of space Parkway Properties got back last year, according to Mike Fransen, vice president and asset manager for Parkway Properties' local portfolio. The Jackson, MS-based REIT has owned 1401 Enclave Pkwy. since 2007, and it underwrote the 209,000-square-foot office building with the expectation that Parker Drilling would vacate 52,000 square feet – the entire fifth and sixth floors – when it relocated to Greenway Plaza.

"We started marketing the space almost immediately, and we thought we had found the perfect tenant for the majority of the space in December 2008, but when the contract got to the CFO's desk, he was concerned about what happening in the economy, and the company decided not to take the space," Fransen tells GlobeSt.com. "At that point, we had to ramp up our efforts to fill the space, and we toured just about every sizeable deal that was looking in the Energy Corridor."
