Jock Howland, managing director with Jones Lang LaSalle, represented M3 Capital in the lease. "They really wanted to focus on the West Loop and to remain close to the train stations," Howland tells GlobeSt.com. "They wanted to be in a first-class building with first-class neighbors."

M3 Capital, formed by partners of Macquarie Capital Partners LLC in December 2006, now occupies 16,800 sf at One N. Wacker, another Buck building. Howland also represented Macquarie in that lease in 2004. "They would have loved to stay in that building, but there was no vacancy," Howland. "When it came time for them to look to move, the best solution for them turned out to be the next new building that the Buck company was developing."

In its spin-off from Macquarie, M3 will move out of 1 N. Wacker in December. The company will temporarily occupy about 16,000 sf on the 52nd floor of the Sears Tower, 233 S. Wacker, until its space in 155 N. Wacker is ready. Howland says Buck has been successful in landing tenants for its new venture, which is already about 60% preleased.
