In the larger of the two signings, IXIS North America Inc. has leased two full floors totaling 71,681 sf. The firm will initially occupy 55,198 sf for a 15-year term and will take up the rest of the space five years after the lease term starts.

IXIS North America, which was represented in the transaction by Michael Goldman of Studley, is one of the subsidiaries that make up the US capital markets arm of IXIS Corporate & Investment Bank. Based in France, the company is a member of Group Caisse d'Epargne.

As far as the other new tenant, HQ Global Workplaces has taken a total of 22,229 sf. The provider of temporary office suites has signed on for a period of 10 years. In the case of both transactions, Mack-Cali was represented by Mark Ravesloot of the New York office of CB Richard Ellis, and in-house by Jane Greenblatt, senior director of leasing and development. Further terms of the signings were not disclosed.

The two new leases bring Harborside Financial Center Plaza 5 to the 87% leased mark. Other tenants on the current roster include Ameritrade, Bigelow Asset Management, Forest Laboratories, Garban Intercapital, Hay Acquisitions, Mitsui, Moody's Investors Services and SunAmerica, among a number of others.

"Harborside's appeal is as a headquarters location," says Mitchell E. Hersh, Mack-Cali's president and chief executive officer. "The location also has attractive financial incentives."

The building is part of the larger Harborside Financial Center, a complex of six office towers totaling more than 3.6 million sf. The REIT retains ownership of five of the towers and continues to manage the sixth. A 350-room Hyatt Regency Hotel is also part of the complex.
