The tenant is Mitsui & Co.--one of the 40-year-old building's original tenants--which has re-upped for 85,000 sf for the next 15 years. The lease begins immediately, over-riding the current deal, which is set to expire in 2005.

The deal was handled exclusively by the brokerage firm, and Derrick Ades, Ken Meyerson and Bruce Weinberg spoke for the tenant while Keith Caggiano, Jon Zuckerman and Stephen B. Siegel represented the building owner, MetLife. The firm has been handling the management and leasing duties on its headquarters building since November of 2001, when San Francisco-based Shorenstein bowed out.

Terms of the deal were being kept under wraps, but sources familiar with the deal have placed the Mitsui agreement between $55 and $60 per foot. Rents in the 2.8-million-sf 200 Park have been placed in the mid $60s.

Insignia has made some splashy deals around town of late--especially in the lower Manhattan subsector. These include the nearly 500,000 sf Insignia landed for Health Insurance Plan of New York and the 157,000-foot deal it carved out for Teachers' Retirement system, both at 55 Water St.

Management and leasing for 200 Park came for Insignia at the same time as the 425,000-sf foot Fred F. French Building at 551 Fifth Avenue. Shorenstein had both buildings in its portfolio for about decade prior to the switch.
