Securities exchange adds 22,000 s/f at Wells REIT's 60 Broad Street.

International Securities Exchange Inc., the world's largest equity options exchange, expanded its lease at 60 Broad Street by 22,135 s/f for 10 years, increasing its presence in the building to nearly 65,000 square feet.

The leasing efforts on behalf of ISE were led by the Newmark Knight Frank team of managing directors Robert Eisenberg and Jeffrey I. Peck together with Mark S. Weiss, executive vice president and principal.

ISE previously leased floors 26 through 28 from the landlord, Wells Real Estate Investment Trust, and subleased a portion of the 31st floor.

This new transaction includes a direct lease with Wells Real Estate Investment Trust for 12,275 square feet on the entire 29th floor.

In addition, when its sublease on the 31st floor expires, ISE will lease the space directly from Wells Real Estate Investment Trust to run coterminous with the balance of its floors.

Arthur Stern and Anthony Stapleton of Cogswell Realty Group represented Wells Real Estate Investment Trust in the transaction.

"ISE needed to expand but did not want to split its operations. We worked together with Wells Real Estate Investment Trust to assemble the additional space," Peck explained.

"This is an expansion of an innovative tenant. It is truly an exciting, fast-growing dynamic company," added Eisenberg.

In May 2000, ISE launched the first fully electronic options exchange in the United States, and since that time, has grown rapidly. In 2003, it traded its 250-millionth contract, making ISE the largest U.S. equity options exchange and, in March 2005, ISE became the first securities exchange to sell its shares in an initial public offering.
