Financial Results

New York, NY, October 21, 2003 - SL Green Realty Corp. (NYSE:SLG) reported a 1% increase in operating results for the three months ended September 30, 2003. During this period, funds from operations (FFO) before minority interests totaled $31.8 million, or $0.87 per share (diluted), compared to $30.3 million, or $0.86 per share (diluted), for the same quarter in 2002.

For the nine months ended September 30, 2003, operating results improved 6% as FFO before minority interest totaled $93.6 million, or $2.59 per share (diluted), compared to $85.6 million, or $2.45 per share (diluted), for the same period in 2002. The increase is primarily attributable to the acquisitions of 220 East 42nd Street and condominium interests in 125 Broad Street in the first quarter of 2003.

Net income available to common shareholders for the third quarter of 2003 totaled $19.4 million, or $0.59 per share (diluted), a 9% increase as compared to the same quarter in 2002 when net income totaled $17.0 million, or $0.54 per share (diluted). The increase in net income is primarily due to the $3.7 million ($0.10 per share) gain from the sale of 1370 Broadway, partially offset by increased depreciation expense from the first quarter 2003 acquisitions of 220 East 42nd Street and condominium interests in 125 Broad Street.

Net income available to common shareholders for the nine months ended September 30, 2003 totaled $68.9 million, or $2.09 per share (diluted), an increase of 35% as compared to the same period in 2002 when net income totaled $47.9 million, or $1.55 per share (diluted). The increase is primarily due to $21.3 million in gains on the sales of 50 West 23rd Street and 1370 Broadway.

The Company's third quarter weighted average diluted shares outstanding increased 1.4 million, or 4%, to 39.2 million in 2003 from 37.8 million in 2002. The increase is primarily attributable to (i) the issuance of units of limited partnership interests in the Company's operating partnership in connection with the acquisitions of 220 East 42nd Street and condominium interests in 125 Broad Street in the first quarter of 2003, (ii) employee stock grants and stock option redemptions and (iii) additional dilution from outstanding stock options.

Consolidated Results

Total quarterly revenues increased 34% in the third quarter of 2003 to $81.3 million compared to $60.8 million in the same quarter in 2002. The $20.5 million growth in revenue resulted primarily from the following items:

• $14.7 million increase from 2003 acquisitions
• $6.4 million increase from the 2003 same-store portfolio
• $1.4 million increase from affiliates that were previously unconsolidated entities
• $2.0 million decrease in preferred and investment income

The Company's EBITDA increased $5.3 million to $42.7 million. The following items primarily drove the EBITDA increase:

• $3.1 million increase from GAAP NOI
  • $7.4 million increase from 2003 property acquisitions
  • $0.8 million increase from same-store properties
  • $2.8 million decrease in income from unconsolidated joint ventures
  • $2.4 million decrease from reduced income from discontinued operations
• $2.4 million increase from discontinued operations which reduced GAAP NOI
• $1.3 million increase in other income primarily due to gain on sale of other assets
• $0.2 million increase from reduced MG&A expense and
• $2.0 million decrease in investment and preferred income

EBITDA margins (EBITDA divided by total revenue) before ground rent decreased to 62.7% compared to 75.1% for the same period last year. After ground rent, EBITDA margins decreased to 58.1% from 69.2% in the corresponding period. The reductions in margins were primarily due to (i) the reduction in investment income and preferred equity investment income, which decreased primarily due to lower outstanding balances, and (ii) increased operating costs.

FFO improved $1.4 million primarily as a result of:

• $5.3 million increase in EBITDA
• $0.4 million increase in FFO adjustment from unconsolidated joint ventures
• $0.2 million increase from reduced preferred stock dividends
• $0.2 million decrease from higher amortization of finance costs
• $1.7 million decrease in FFO from discontinued operations
• $2.7 million decrease from higher interest expense

The $2.7 million increase in interest expense was primarily associated with higher average debt levels associated with new investment activity ($3.8 million) and the funding of ongoing capital projects and working capital requirements ($0.1 million). These increases were partially offset by reduced loan balances due to previous disposition activity ($1.3 million) and lower interest rates ($0.1 million).

The 2002 results have been restated to classify the operating results of 2003 sales as income from discontinued operations. The properties sold in 2003, which are included in this restatement, are 50 West 23rd Street (March 2003), 875 Bridgeport Avenue, Shelton, Connecticut (May 2003), and 1370 Broadway (July 2003).

Same-Store Results

During the third quarter of 2003, same-store cash NOI increased $0.5 million to $26.1 million, as compared to $25.6 million over the same quarter in 2002. The increase in same-store cash NOI was driven by a $4.5 million (9%) increase in cash revenue. This increase in cash revenue was primarily due to:

• $0.4 million increase from replacement rents, which were 9% higher than previously fully escalated rents, including early renewals and contractual rent steps and reduced free rent ($0.2 million)
• $0.4 million increase from higher weighted average occupancy in 2003 (97.5%) compared to 2002 (96.7%)
• $3.6 million increase in escalation and reimbursement revenue primarily due to real estate tax reimbursements ($2.3 million), higher operating expense escalations ($0.4 million) and increased electric reimbursements ($0.5 million)

However, cash NOI margins before ground rent decreased year over year from 53.2% to 50.6%. The decrease in operating margins was primarily due to the $4.0 million (16%) increase in operating expenses resulted from the following:

• $2.1 million (29%) increase in real estate taxes
• $0.9 million (322%) increase in insurance costs
• $0.4 million (21%) increase in repairs, maintenance and security expenses
• $0.2 million (16%) increase in management, professional and advertising costs
• $0.2 million (4%) increase in utility costs

Approximately 90% of the quarterly electric expense was recovered through the utility clause in tenant leases and approximately 35% of the quarterly real estate tax expense was recovered through the escalation clause in tenant leases.

Leasing Activity

For the third quarter of 2003, the Company signed 69 office leases totaling approximately 275,000 rentable square feet with starting office cash rents averaging $33.90 per square foot, a 3.2% increase over previously fully-escalated cash rents averaging $32.86 per square foot. Tenant concessions averaged 1.1 months of free rent with an allowance for tenant improvements of $16.49 per rentable square foot. This leasing activity includes early renewals for 11 office leases totaling approximately 103,000 rentable square feet. Including retail and storage, the Company's quarterly leasing activity totaled 75 signed leases for approximately 289,000 rentable square feet.

For the nine months ended September 30, 2003, the Company signed 194 office leases totaling approximately 904,000 rentable square feet with starting office cash rents averaging $33.99 per square foot, a 5.9% increase over previously fully-escalated cash rents averaging $32.10 per square foot. Tenant concessions averaged 2.1 months of free rent with an allowance for tenant improvements of $18.64 per rentable square foot. This leasing activity includes early renewals for 24 office leases totaling approximately 157,000 rentable square feet.

Real Estate Activity

1370 Broadway
New York, New York

On July 31, 2003 the Company sold 1370 Broadway for total consideration of $58.5 million, or $234 per square foot. This sale resulted in a gain of approximately $4.0 million. The $18.5 million taxable gain, inclusive of the deferred gain from the prior sale of 17 Battery South, was deferred into the acquisition of 461 Fifth Avenue.

461 Fifth Avenue
New York, New York

On October 1, 2003, the Company acquired the long-term leasehold interest in 461 Fifth Avenue for $60.9 million, or $305 per square foot. The Company's initially announced purchase price of $62.3 million was subsequently reduced by $1.4 million of purchase price adjustments received at closing. The going-in unlevered cash NOI yield on investment is 7.92%. The leasehold acquisition was funded, in part, with the proceeds from the sale of 1370 Broadway. As a 1031 tax-free exchange, the transaction enabled the Company to defer gains from the sale of 1370 Broadway and from the sale of 17 Battery Place South, which gain was initially re-invested in 1370 Broadway. The balance of the acquisition was funded using the Company's unsecured line of credit.

125 Broad Street
New York, New York

During the quarter, the Company exercised an option to acquire its portion of the underlying fee interest in 125 Broad Street for approximately $5.9 million. This transaction is scheduled to close in the third quarter of 2004.

321 West 44th Street
New York, New York

The joint venture, comprised of the Company and Morgan Stanley Real Estate Fund III, L.P. ("MSREF") has entered into an agreement to sell 321 West 44th Street to Thor Equities LLC. The sale price is $35.0 million, or approximately $172 per square foot. 321 West 44th Street is a ten- story office building located mid-block between Eighth and Ninth Avenues on 44th Street. The Company purchased 321 West 44th in March 1998 for $17.0 million. In May 2000, the Company contributed the property into a joint venture with MSREF and retained a 35% ownership interest.

Structured Finance Activity

During the third quarter of 2003, the Company originated $70.0 million of structured finance investments with an initial yield of 10.1%. In July 2003, the Company received proceeds from a redemption totaling $27.6 million.

As of September 30, 2003, the par value of the Company's structured finance and preferred equity investments totaled $168.0 million. The weighted average balance outstanding for the third quarter was $128.0 million. During the third quarter 2003, the weighted average yield was 11.3% and the third quarter end run rate is 11.4%.

Financing Activity

180 Madison Mortgage Financing

In July 2003, the Company completed a $45.0 million first mortgage refinancing of the property located at 180 Madison Avenue, owned through a joint venture with Morgan Stanley Real Estate Fund. The mortgage bears interest at a fixed rate of 4.57% per annum and matures in July 2008. The financing proceeds were used to pay off the existing $31.6 million first mortgage. The Company's share of proceeds totaled $6.0 million and was used to reduce the outstanding balance on the Company's unsecured line of credit.

Conversion of Preferred Income
Equity Redeemable Shares

On September 30, 2003, the Company converted all 4.6 million of the outstanding shares of its 8.0% Series A Preferred Income Equity Redeemable Shares ("PIERS" (SM)). Each share of the PIERS was converted into common stock at the rate of 1.0215 resulting in a 4.7 million common share issuance. Dividends were paid on the PIERS through the conversion date. The Company did not recognize an earnings charge on the conversion because the transaction did not involve either a redemption or an induced conversion.

Forward Swap Contract

During October 2003, the Company entered into a $35.0 million five-year forward serial swap in connection with the anticipated final December 2003 draw from the $200 million unsecured term loan. The forward swap is stepped with a one-year rate of 2.95% that will increase to 5.61% in December 2004 through the term loan maturity date in June 2008.
