Press Release Details

New York, NY - November 11, 2008 - SL Green Realty Corp. (NYSE: SLG) today announced that Viacom International, Inc. has renewed and extended its lease covering 1.3 million square feet for its Global Headquarters at 1515 Broadway. This notable accomplishment is the third largest lease ever signed in Midtown Manhattan. The iconic tower is owned by SL Green in a joint venture with SITQ. The lease renewal through mid-2015 includes 1.1 million square feet that was scheduled to expire in 2010, along with the extension of an additional 170,000 square feet that was set to expire in 2012 and 2013.

Marc Holliday, Chief Executive Officer of SL Green, stated, "For more than a decade Times Square has been the epicenter of corporate resurgence in Manhattan and 1515 Broadway stands prominently at this "Crossroads of the World". Along with our joint venture partner SITQ, we are extremely pleased that Viacom, which has been a long time Midtown anchor and valued tenant, will continue to call 1515 Broadway its home. Additionally, the transaction will allow us to redesign our previously planned redevelopment and save over $200 million of potential re-tenanting costs."

He continued, "SL Green continues to outperform its leasing objectives in a challenging economic climate. In 2008, we have completed over 3 million square feet of transactions, including numerous early renewals -- a noteworthy achievement that reduces future leasing risk and enhances our 2009 and 2010 revenue outlook. In completing the renewal announced today, we have reduced the amount of square footage of leases expiring over the next two years by approximately 30%."

Mr. Holliday added, "Times Square is a place that continually reinvents itself in the image of visitors and of those who work there. It's essential that its most recognizable building continues to play a leading role in that evolution."

Acquired by the SL Green/SITQ joint venture in 2002, 1515 Broadway was among the skyscrapers that pioneered the transformation of Times Square to become one of the City's foremost office locations. In addition to being anchored by Viacom, the now 95% leased office tower is also home to The Minskoff Theatre, AEG Live's Nokia Theatre and the recently signed Wurk Environments, LLC.

Michael Langinestra, Scott Gottlieb and Andrew Sussman from CB Richard Ellis Inc. and the legal team of Chris Smith and Laura Chirita from Shearman & Sterling LLP represented Viacom in the transaction. SL Green was represented in-house by Steven Durels, Executive Vice President, Neil Kessner, Executive Vice President, and Kathy Crocco, Senior Vice President together with attorneys Stuart Mass and Noah Shapiro from Paul, Hastings, Janofsky & Walker LLP.
