The lease, which reportedly was due to expire next August, now runs until 2022, and includes two options for renewal, as well as options for expansion, according to a release. Mintz Levin first opened a New York office at 666 Third in 2000 with six attorneys and 34,000 square feet of space, and now houses 76 attorneys and 54 other employees there.

"Once the economic framework was set on this transaction, the real estate committee of Mintz Levin, Tishman Speyer and Newmark Knight Frank worked collaboratively in solving the logistical items necessary to accommodate a re-stack in a full building," says Mark Weiss, vice chairman of Newmark Knight Frank, in a release. Mintz Levin had occupied non-contiguous floors at the Tishman Speyer-owned property.

Weiss represented the law firm in negotiations. Adjacent to the landmark Chrysler Building, Chrysler East was built in 1951 and was formerly known as the Kent Building before Tishman Speyer undertook a repositioning program at 666 Third. The two properties are collectively known as the Chrysler Center.
