Software developer Exa Corp. has signed a seven-year lease renewal for 44,241 square feet at 55 Network Drive in Burlington.
The second-floor space serves as Exa’s world headquarters, which is being renovated in a flexible and collaborative office space environment designed by Spagnolo Gisness & Assoc. of Boston.
JLL’s Tamie Thompson and Tyler Spring represented Exa in the negotiations with landlord Nordblom Co., which was represented by Adele Olivier and Patrick O’Neill.
The 1-million-square-foot Network Drive park is now 98 percent leased. The 158-acre campus also contains a 270,000-square-foot build-to-suit site at 25 Network Drive.
