Strategic Rationale This transaction reinforces SLG’s position as the premier landlord in NYC Properties totaling 24.3 million square feet $1.01 billion of combined NYC revenues (1) 1,228 tenants Reckson acquisition will provide substantial accretion Synergies in excess of $20 million Projected accretion in 2007: $0.20 - $0.40 per share Initial Pro forma FFO guidance for 2007: $5.25 per share There is significant upside to the retained Reckson portfolio from below-market rents and SLG operating initiatives CBD office portfolio in-place rents are an estimated 25% below market rates 1185 Avenue of the Americas and 1350 Avenue of the Americas have substantial near term lease rollover Transaction offers unique opportunity to acquire high quality assets in irreplaceable locations at a discount to replacement cost Provides SLG with the opportunity to realize gains from the immediate disposition of non-core Reckson assets, while retaining selective suburban exposure to offer tenants an alternative to Manhattan escalating rents Enables SLG to continue the selective disposition of its own non-core assets which can be deployed into Reckson assets on a tax-efficient basis (1) Annualized 1Q06 rent as reported in companies’ financial supplementals.
