New York, NY, July 25, 2005 - SL Green Realty Corp. (NYSE: SLG) today reported funds from operations available to common stockholders, or FFO, of $46.4 million, or $1.02 per share for the second quarter ended June 30, 2005, a 1.9% decrease over the same quarter in 2004. Excluding the incentive fee received in 2004 in connection with the recapitalization of One Park Avenue ($4.3 million or $0.10 per share), FFO increased 8.5% for the second quarter. The Company also reported FFO of $2.01 per share for the six months ended June 30, 2005, a 7.5% increase over the same period in 2004, which was $1.87 per share.

Operating and Leasing Activity

For the second quarter of 2005, revenues and EBITDA of $106.1 million and $64.2 million, respectively, increased $23.4 million (or 28%) and $10.2 million (or 19%), respectively, over the same period in 2004, largely due to the new acquisitions described above. Same-store GAAP NOI increased 2.4% to $35.7 million during the second quarter for the wholly-owned properties and 8.5% to $23.0 million for the joint venture properties.

Average starting office rents of $43.49 per rentable square foot for the second quarter represented a 1.7% increase over the previously fully escalated rents.

During the second quarter the Company had a net increase in the size of its portfolio by approximately 1.0 million square feet, which increased total useable square feet under ownership from 17.4 million to 18.4 million square feet. In addition the Company owns 267,000 square feet of office space at One Madison Avenue, which it intends to convert into residential condominiums. Occupancy for the portfolio increased from 95.7% at

March 31, 2005 to 95.9% at June 30, 2005. During the quarter, the Company signed 75 leases totaling 387,313 square feet with 71, and 386,134 square feet, representing office leases.

Significant leasing activities during the second quarter included:

• 71 office leases totaling approximately 386,134 square feet were signed, representing a significant increase in the average size lease when compared to 70 office leases totaling 342,000 square feet signed during the same period in 2004.

• New lease with Omnicom Group for approximately 33,000 square feet at 220 East 42^nd Street.

• Renewal of Solomon-Page Group for approximately 36,000 square feet at 1140 Avenue of the Americas.

• Renewal of Morgan Stanley & Co., Incorporated for approximately 95,000 square feet at 1221 Avenue of the Americas.

Real Estate Investment Activity

During the second quarter of 2005, the Company announced acquisitions totaling approximately $1.0 billion and dispositions totaling approximately $60.5 million.

Investment activity announced during the second quarter included:

• Acquisition of the fee interest in One Madison Avenue from Metropolitan Life Insurance Company (MetLife) for $918.0 million (excluding transaction costs). One Madison Avenue consists of two contiguous buildings - the South Building and the North Tower - totaling approximately 1.4 million square feet. The South Building, which consists of approximately 1.2 million square feet, was acquired, pursuant to a joint venture agreement with Gramercy Capital Corp., for $803.0 million. SL Green owns a 55% interest in the joint venture. The building is 95.5% net leased to Credit Suisse First Boston, or CSFB, through 2020. The North Tower, which consists of 267,000 square feet and is zoned for residential and office use, was acquired for $115.0 million. SL Green and CSFB currently intend to physically separate the South Building and the North Tower and convert the North Tower to residential condominium units. SL Green and CSFB will share in the profits of the residential component. The South Building acquisition was funded by a $690.0 million 15-year mortgage with a fixed interest rate of 5.91 percent per annum. The North Tower acquisition was funded by a $115.0 million two-year loan with an interest rate of 275 basis points over the 30-day LIBOR. Approximately $98.0 million was drawn at closing.

• Acquisition of partnership interest in 19 West 44th Street from its partner, the City Investment Fund, or CIF, resulting in majority ownership and control of the property. The transaction valued the property at $91.2 million. Pursuant to the terms of the initial joint venture agreement, SL Green would have been entitled to an incentive fee of approximately $7.3 million upon a sale of the property. With the interests being acquired by SL Green, the incentive fee income will be deferred and reflected as a reduction to the Company’s basis in the property to approximately $79.2 million, or $272 per square foot. In addition, SL Green originated a loan secured by CIF’s remaining ownership stake. CIF also granted SL Green an option to purchase CIF’s remaining equity interest.

• Sale of the fee interest in 1414 Avenue of the Americas for $60.5 million, or approximately $500 per square foot. The property is approximately 121,000

square feet. The Company recognized a gain on sale of approximately $35.9 million. The sale was effectuated through a reverse 1031 exchange with 625 Madison Avenue, which resulted in substantially all of the taxable gain on sale being deferred.

Financing and Capital Activity

• In June 2005, the Company completed a $120.0 million 10-year interest-only mortgage refinancing of the property located at 711 Third Avenue. The mortgage bears interest at a fixed rate of 4.99% per annum. The refinancing proceeds were used to pay down the Company’s unsecured revolving line of credit.

• In June 2005, the Company issued $100.0 million of Trust Preferred Securities, which are reflected on the balance sheet at June 30, 2005 as Junior Subordinate Deferrable Interest Debentures. The proceeds were used to repay the Company’s unsecured revolving credit facility. The $100.0 million of junior subordinate deferred interest debentures have a 30-year term ending July 2035. They bear interest at a fixed rate of 5.61% for the first 10 years ending July 2015. Thereafter, the rate will float at three month LIBOR plus 1.25%. The securities are redeemable at par beginning in July 2010.

• In May 2005, the Company increased an existing term loan from $100.0 million to $200.0 million while simultaneously reducing the interest rate by 25 basis points to LIBOR plus 125. The maturity was also extended through May 2010.

Structured Finance Activity

The Company’s structured finance investments totaled $396.9 million on June 30, 2005, a net increase of $21.8 million from March 31, 2005. The structured finance investments currently have a weighted average maturity of 6.6 years. The weighted average yield for the quarter ended June 30, 2005 was 10.27%, down slightly from 10.43% for the quarter ended March 31, 2005.

Investment In Gramercy Capital Corp.

Fees earned from various agreements between the Company and Gramercy Capital Corp. (NYSE: GKK) totaled approximately $1.9 million for the quarter ended June 30, 2005. The Company’s share of FFO generated from its investment of 4.7 million shares in Gramercy totaled approximately $2.2 million for the quarter ended June 30, 2005.
