Pegasus corporate chiefs had narrowed the choice to the firm's addresses in Dallas and Phoenix, James S. Vanderslice, president of GLV Realty Advisors in Dallas, tells GlobeSt.com. The 16,000-sf, class A lease, now resting at 8350 N. Central Expressway, was launched at a flat rate with a co-terminus expiration of the 83,000-sf headquarters pact which expires in 2012, he says.

Pegasus last week opened doors on the extra floor, which is contiguous to its others in Campbell Centre. As Pegasus' corporate account broker, Vanderslice negotiated the expansion with the Trammell Crow Co. team of Michael Feldt and Randy Shipman, who represented GE Capital, owner of the 20-story, 431,000-sf building.

A renovated historic property in the Dallas CBD landed Gabbert & Associates, which is relocating from North Market Street into a 3,116-sf office under a two-year lease. The firm was swayed to sign by the historic location and renovation, says a spokeswoman for Dallas-based International Capital Inc. The 127,000-sf 501 Elm St. is across from Dealey Plaza and adjacent to the JFK Sixth Floor Museum in the West End.

Also inbound to 501 Elm St. is WebDirect Advertising, a startup that penned a one-year lease for a 1,644-sf office. Scott Ehley of the John Bowles Co. in Dallas, the building owner's broker, single-handedly structured both transactions for 501 Elm St.

At Carillon Towers, TCG Dallas renewed a 13,358-sf office in a stair-stepped, 10-year lease for the 261,275-sf office building owned by KBS Realty Advisors of Newport Beach, CA. The telecommunications service provider, an 11-year tenant, re-upped on the same amount of space to keep the building at 75% occupancy.

Matt Didyk of Transwestern Commercial Services' Dallas office represented KBS Realty. The tenant's parent, AT&T Corp., had Karlos McGhee, global real estate manager, negotiating its terms for a building with a quoted rate of $16 per sf.

At the Princeton at 14651 Dallas Parkway, Halliburton Investor Relations LLC took 4,808 sf in a seven-year lease. The deal doubled Halliburton's space and slides the operation into a "prominent Tollway building at very reasonable rates," Allan Halliburton, president of investor relations, said in a press release.

Evan Reynolds, president of the Reynolds Co. in Dallas, represented Halliburton. Darryl Cothron of Houston-based PM Realty Group's Dallas office bargained for the building owner.

A 2,227-sf renewal was cut by Generation Next Telecommunications Inc. for Park Centre at 850 Central Parkway in Plano. Glen Kirksey and Perry Jones, both with Property Advisers Realty Inc. in Irving, negotiated the straight-up renewal.

A 4,703-sf office sublease put Claimsnet.com Inc. into "as-is" class B space leased to the Texas Society of CPAs, which continues to occupy the first floor of 14860 Montford Dr. The dot-com signed for the balance of the two-year term on the second floor at a significant discount off the market rate, says Steven Schneider of Grubb & Ellis Co. in Dallas. Chris Mickey of CB Richard Ellis Inc.'s Dallas office represented the Texas society in the transaction.
