SL GREEN REALTY CORP. FIRST QUARTER 2001 UNAUDITED ================================================================================ FINANCIAL HIGHLIGHTS EARNINGS PERFORMANCE o First quarter Funds From Operations (FFO) were $21.2 million or $0.73 per share (diluted), 18% better than one year ago, when FFO was $17.2 million or $0.62 per share (diluted). Quarterly FFO results exclude an extraordinary loss due to an early debt extinguishment of $0.1 million, the $1.5 million gain on the sale of 633 Third Avenue in 2001 and the $14.2 million gain of the sales of 36 West 44th Street and 29 West 33rd Street in 2000, and a 2001 cumulative effect of accounting change ($0.5 million) related to the implementation of SFAS 133. o The 18% growth in first quarter FFO reflects contributions from the following: o Consolidated GAAP NOI increased $7.5 million: -- $6.8 million from the 2001 acquisitions of One Park Avenue and 1370 Broadway -- $3.4 million increase from same store properties as GAAP revenue increased $4.4 million, net of the change in credit loss, (i) $3.9 million in rental revenue as GAAP replacement rents were 56% higher than the previously fully escalated rents and (ii) increased escalation and reimbursement income ($1.6 million) related to the increased recovery ($1.0 million) of higher electric expense resulting from the higher electric rates, and increased operating expense escalations ($0.5 million). The increased electric recovery represented an 82% recovery rate on the increased electric costs. Revenue gains were partially offset by $1.8 million of higher operating costs, which resulted from: higher utility costs ($1.4 million) primarily due to higher electric rates ($1.0 million) and higher fuel and gas costs ($0.4 million). -- $0.7 million increase from the Company's joint ventures. -- $3.0 million decrease from wholly owned properties sold (29 West 34th Street, Bar Building, 17 Battery South and 633 Third Avenue) or contributed to a joint venture (321 West 44th Street). o Investment income increased $2.3 million due to (i) increased investment in structured finance ($2.2 million) and interest income earned on proceeds from the sale of 17 Battery South ($0.1 million). 4

o The Company had higher interest costs ($4.4 million) associated with: higher average debt levels due to net acquisition and new structured finance activity ($4.3 million), and the higher average debt levels due to the funding of ongoing capital projects and working capital requirements ($0.4 million). The increase was partially offset by lower interest rates from floating rate debt ($0.3 million). o MG&A expense increased $0.8 million from higher personnel costs due to several executive management changes. o Non-real estate depreciation increased $0.1 million due to additional amortization of financing costs primarily associated with the company's new line of credit. o Equity in (loss) income in service corporation and subsidiaries decreased $0.4 million due to lower tenant-rep income ($0.2 million) and an increased loss from Emerge ($0.2 million) due to one-time start-up costs associated with the expansion of the e.Emerge operation. OPERATING MARGINS QUARTERLY o Cash NOI in the 2001 "same store" portfolio rose $4.2 million (17%) from $23.9 million to $28.1 million, and operating margins improved from 56.8% to 59.2%. GAAP NOI increased by $2.5 million to $21.6 million, or approximately 13% over a year ago, and GAAP operating margins after ground rent improved from 56.6% to 57.4%. One of the primary drivers increasing same store cash NOI is the $5.2 million (11%) increase in total revenue combined with a $0.8 million reduction in free rent and straight line rent, resulting in a $6.0 million (14%) increase in cash revenue. The $0.7 decrease in free rent is primarily due to 420 Lexington Avenue ($0.4 million), 440 Ninth Avenue ($0.1 million), and 290 Madison Avenue ($0.1 million). The decrease in free rent is due to reduced free rent in the 2001 lease concession packages and reduced leasing activity as compared to the 2000 first quarter. The $5.2 million increase in total revenue is due to: 1. An increase in rent revenue of $3.2 million resulting from higher replacement rents approximately on 554,000 square feet which were 47% greater than previously fully escalated rents primarily at 420 Lexington Avenue ($1.5 million), 711 Third Avenue ($0.5 million), 1372 Broadway ($0.4 million) and 440 Ninth Avenue ($0.3 million). 2. The balance of the increase is due to higher escalation and reimbursement income ($1.6 million), consisting of electric reimbursement ($1.0 million) and increased operating escalation income ($0.5 million). 5

3. Leasing of 50,000 square feet of previously vacant space ($0.7 million). Partially offsetting the total revenue increase were increased operating expenses ($1.8 million) primarily due to higher utility costs ($1.4 million) and higher payroll costs ($0.3 million). NOTE: See Page 9 for a list of the properties, which comprise the 2001 same store portfolio. o The Company's consolidated first quarter EBITDA margins before ground rent improved to 64.2% compared to 60.8% for 2000. The EBITDA margin after ground rent was 59.2% as compared to 54.8% in the same period of the prior year. These margin improvements are attributable to GAAP NOI growth resulting from (i) an average improvement in replacement rents over this 12-month period of 42% versus previously fully escalated rents, (ii) income from unconsolidated joint ventures, (iii) income from structured finance and (iv) property acquisitions net of property dispositions. QUARTERLY LEASING HIGHLIGHTS o Vacancy at December 31, 2000 was 204,879 useable square feet net of holdover tenants. During the quarter, 101,707 additional useable square feet became available at an average escalated cash rent of $32.37 per rentable square foot. The company also acquired 72,340 vacant useable square feet with the first quarter acquisitions of 469 Seventh Avenue 1370 Broadway and One Park Avenue. Space available to lease during the quarter totaled 378,926 useable square feet, or 3.8% of the total portfolio. o During the first quarter, 45 leases were signed totaling 101,932 useable office square feet with new cash rents averaging $40.05 per rentable square foot. Replacement rents were 42% greater than rents on previously occupied space, which had a fully escalated cash rent averaging $28.19 per rentable square foot. Average tenant concessions were one month of free rent and tenant build-out allowance of $9.01 per rentable square foot. Including early renewals and excluding holdover tenants, the tenant renewal rate was 48%. 7 leases have expired comprising 14,854 useable square feet that are in a holdover status. This results in 262,140 useable square feet remaining vacant at March 31, 2001. o The Company signed 2 leases for 8,482 useable square feet that was for the early renewal of a office tenants. The early renewals were for space that was not scheduled to become available until after 2001. The Company was able to renew the current tenants at an average cash rent of $47.98 representing an increase of 34.0% over the previously escalated rents of $35.81. 6

In-place rents are approximately $27.72 per square foot, approximately 34% below current market levels.

In April 2001 the Company received $50.1 million in proceeds from the early redemption of an outstanding mezzanine loan position. The loan had an anticipated maturity date in September 2001. The loan had an original issue discount that has been accelerated and will result in an increase to second quarter investment income totaling $2.1 million. 7
