JP Morgan is renewing its 11th floor digs in both towers, holding onto 59,876 square feet. JP repped itself in the transaction. Bitwave, meanwhile, took a long-view look at its 20,190 square feet on the floor seven in Tower 3. The fabless semiconductor company was repped by Parsons Commercial Group.

Two additional leases for Verizon--63,540 square feet-- and Cass Information Systems, Inc.--17,500 square feet--which were both leased over the summer, help keep the towers close to filled with only 145,000 square feet still available. CB Richard Ellis and CresaPartners, respectively, represented each company.

"One of the interesting impacts of these leases is the potential statement being made to the market by a fairly diversified group of large companies," says John Wilson, partner of Richard Barry Joyce & Partners, in a statement. "I've got a hunch that, given their completely independent decisions to remain in place and commit long term, there may be other firms who have been evaluating their locations who my choose on the same strategy. Instead of making no decision, they might see this as [a] sign of confidence that it's time [to] go long term instead of year to year."
