Ameriprise Financial to Lease 20,000 SF at 7 WTC
01/04/2006

NEW YORK — January 4, 2006 — Silverstein Properties and Ameriprise Financial, Inc. (NYSE: AMP) today announced that Ameriprise Financial, a leading financial planning, asset management and insurance company, has signed a 10-year lease for approximately 20,000 sq. ft. covering half of the 39th floor at 7 World Trade Center. CB Richard Ellis, exclusive leasing agent for 7 WTC, represented Silverstein Properties in the transaction. Trammell Crow Company represented Ameriprise Financial. The announcement comes on the heels of the New York Academy of Sciences' 40,000-sq. ft. lease signed on December 15, 2005.

"We are pleased to announce another lease at 7 World Trade Center," said Josef Mittlemann, Chief Operating Officer of Silverstein Properties, who has taken an active role to help accelerate the transaction making process. "I want to thank the brokers and attorneys who helped bring about this transaction. We are delighted to welcome Ameriprise Financial to the building, and with the New York Academy of Sciences' deal closed and others in the pipeline accelerating, we look forward to a very successful 2006."

Ameriprise Financial's New York City office move follows the company's recent spin-off from American Express, which was completed on September 30, 2005. The Minneapolis-based company currently maintains space in American Express locations in Lower Manhattan and the new location will include executive offices and office space for New York City-based employees currently working in American Express locations. The company expects to move into the building by mid-2006.

"Now that Ameriprise Financial is an independent company, we are retaining our presence in Lower Manhattan by relocating our New York City corporate offices from existing American Express offices to the 7 World Trade Center building," said Jim Cracchiolo, Chairman and Chief Executive Officer of Ameriprise Financial. "This essentially moves us across the street to an outstanding new location."

Simon Wasserberger, First Vice President of CB Richard Ellis, and Cathy Giliberti of Silverstein Properties handled the negotiation of the lease agreement. Ameriprise Financial was represented by Trammell Crow's James Silberfein, Michael Liss and Richard Fahey. The agency leasing team from CB Richard Ellis is led by Mary Ann Tighe, Chief Executive Officer of the firm's New York Tri-State Region, and Stephen B. Siegel, Chairman, Global Brokerage.

"The New York Academy of Sciences' lease at 7 World Trade Center is indicative of the wide range of tenants willing to call Lower Manhattan home," said Mr. Wasserberger. "But make no mistake: Downtown is the financial capital of the world, and Ameriprise Financial's decision underscores the allure of both the area's great business environment and one of New York's premier new addresses."

The new location will accommodate approximately 50 Ameriprise Financial employees and will have no impact on Minneapolis as a headquarters for the company or Ameriprise financial advisor offices in New York City.
