EDISON, N.J., Jan. 5, 2011 /PRNewswire/ -- Mack-Cali Realty Corporation (NYSE: CLI) today announced that Verizon New Jersey has signed a 5-year lease extension at 600 Horizon Center Drive at Horizon Center Business Park in Hamilton Township, New Jersey. Verizon leases the entire 95,000-square-foot building and now will do so through 2017.

Verizon New Jersey, a unit of Verizon Communications, was represented in the lease transaction by Marc Rosenberg of Cushman & Wakefield.

We believe that relationship, along with the fact that Horizon Center Business Park offers a strategic location, facilitated their decision to make a significant space commitment well in advance of their lease expiration."
