SL GREEN REALTY CORP.

PRO FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

On October 19, 2004, the Company acquired 625 Madison Avenue for $231.5 million, or approximately $415 per square foot. The approximately 558,000 square feet, 17-story building contains 53,000 square feet of retail space and is 68% occupied. The property was acquired with cash and the issuance of approximately 300,000 common units in SL Green Operating Partnership, L.P., valued at $50.50 per unit. The building is also encumbered by a $102 million mortgage loan held by the New York State Teacher’s Retirement System that SL Green assumed upon closing. The mortgage has a fixed annual interest rate of 6.27% and will mature in November 2015. The property being acquired is subject to a ground lease expiring on June 30, 2054, after exercise of all options.

On July 28, 2004, we acquired the property located at 750 Third Avenue and a 30% interest in the property located at 485 Lexington Avenue (collectively the “TIAA Acquisition”).

The unaudited pro forma condensed consolidated balance sheet of SL Green Realty Corp. (the “Company”) as of September 30, 2004 has been prepared as if the Company’s acquisition of the property located at 625 Madison Avenue had been consummated on September 30, 2004. The unaudited pro forma condensed consolidated income statements for the year ended December 31, 2003 and the nine months ended September 30, 2004 are presented as if the Company’s acquisition of the properties located at 625 Madison Avenue, 750 Third Avenue and the 30% interest in 485 Lexington Avenue occurred on January 1, 2003 and the effect was carried forward through the year and the nine month period.

The pro forma condensed consolidated financial statements do not purport to represent what our financial position or results of operations would have been assuming the completion of these acquisitions had occurred on January 1, 2003 and for the period indicated, nor do they purport to project our financial position or results of operations at any future date or for any future period. These pro forma condensed consolidated financial statements should be read in conjunction with our 2003 Annual Report on Form 10-K and our Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2004.

We conducted our audit in accordance with auditing standards generally accepted in the United States of America.  Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the statement of revenues and certain expenses is free from material misstatement.  An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the statement of revenues and certain expenses.  An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation.  We believe that our audit provides a reasonable basis for our opinion.

The accompanying statement of revenues and certain expenses was prepared for the purpose of complying with Rule 3-14 of Regulation S-X of the Securities and Exchange Commission for inclusion in Form 8-K of SL Green Realty Corp. and is not intended to be a complete presentation of the Partnership’s revenues and expenses.

5. Mortgage payable

The Partnership borrowed $55,000,000 under the terms of a Consolidation, Modification and Extension Agreement (“the “Agreement”).  Between 1987 and 1992, the Partnership amended, modified and extended the Agreement and borrowed an additional $51,000,000.  The modified loan agreement was set to mature on December 10, 2004 and bore interest at 10% per annum.  Monthly payments of principal and interest aggregating $994,541 were required until December 10, 2004, at which time the remaining balance of $76,616,951, representing principal and accrued interest, would have been due.
