Operating and Leasing Activity

For the second quarter of 2006, the Company reported revenues and EBITDA of $132.8 million and $76.9 million, respectively, increases of $30.7 million (or 30.1%) and $14.7 million (or 23.7%), respectively, over the same period in 2005, largely due to strong leasing activity at 625 Madison Avenue and 420 Lexington Avenue as well as the acquisitions in 2005 and 2006, including 28 West 44th Street (February 2005), an additional interest in 19 West 44th Street (June 2005) and 521 Fifth Avenue (March 2006). Same-store GAAP NOI on a combined basis increased by 5.3% for the second quarter when compared to the same quarter in 2005, with the wholly-owned properties increasing 7.9% to $47.0 million during the second quarter and the joint venture properties increasing by 0.5% to $24.1 million.

Average starting office rents of $46.40 per rentable square foot for the second quarter represented a 10.3% increase over the previously fully escalated rents.

Occupancy for the portfolio increased from 95.2% at March 31, 2006 to 95.9% at June 30, 2006. During the quarter, the Company signed 60 leases totaling 437,864 square feet, with 57 leases and 427,862 square feet representing office leases.

Real Estate Investment Activity

During the second quarter of 2006, the Company announced new investments totaling approximately $545.5 million.

Investment activity announced during the second quarter included:

- In June 2006, the Company acquired an additional 40% ownership interest in the venture that owns 55 Corporate Drive, N.J., increasing our ownership interest to 50%. This interest is held as a tenant-in-common interest. Subsequent to this acquisition, which valued the property at $236.0 million, the property was refinanced. The mortgage was repaid and replaced by a $190.0 million, ten-year interest-only mortgage with a fixed stated interest rate of 5.75%. The property is net-leased to a single tenant until 2015.

- On June 30, 2006, the Company completed the investment in the previously announced transaction involving 609 Fifth Avenue — a mixed-use property that includes New York City’s American Girl Store and approximately 100,000 square feet of Class A office space — in a transaction that valued the property at approximately $182.0 million. The Company issued approximately 64 million preferred units in SL Green Operating Partnership, L.P., valued at $1.00 per unit, to subsidiaries of 609 Partners, LLC, the partnership that indirectly holds the property, and acquired all of its common partnership interests. The property remains subject to a $102.0 million mortgage loan held by Morgan Stanley Mortgage Capital, Inc. The mortgage has a fixed annual interest rate of 5.85% and will mature in October 2013.

- In May 2006, the Company entered into a joint venture with Mack-Cali Realty Corporation. The joint venture, in which the Company has a 50% ownership interest, acquired interests in seven class A office properties, valued at approximately $127.5 million from entities affiliated with The Gale Company in which entities the Company had a preferred equity investment. The properties, which encompass approximately 900,000 square feet, are subject to $102.5 million of mortgage loans at an effective interest rate of approximately 7.57%.

Financing and Capital Activity

In July 2006, the Company sold 2,500,000 shares of its common stock for net proceeds, after deducting underwriting discounts, commissions and transaction expenses, of approximately $269.1 million. Lehman Brothers acted as sole underwriter for this offering, and was also granted a 30-day option to purchase up to an additional 250,000 shares solely to cover over-allotments.

In April 2006, the Company refinanced the $140.0 million loan on 521 Fifth Avenue with a new $140.0 million five-year loan that bears interest at LIBOR plus 100 basis points. The previous loan bore interest at LIBOR plus 162.5 basis points.

Structured Finance Activity

The Company’s structured finance investments totaled $334.0 million on June 30, 2006, a decrease of $132.2 million over the balance at March 31, 2006. The structured finance investments currently have a weighted average maturity of 7.7 years. The weighted average yield for the quarter ended June 30, 2006 was 10.31%, consistent with the yield for the quarter ended March 31, 2006.

During the second quarter 2006, the Company originated $44.2 million of structured finance investments with an initial yield of 9.74%. This includes an investment in a New York City commercial office property, which Gramercy elected not to make. In addition, the Company received redemptions totaling approximately $176.5 million that were yielding 10.97%.

In May 2006, Mack-Cali Realty Corporation acquired The Gale Company’s interests in the New Jersey properties constituting the Bellmeade portfolio, which interests are in substantially all of the entities in which the Company had a preferred equity investment. This transaction, as well as other redemptions during the quarter, resulted in the recognition of approximately $4.9 million ($0.10 per share) of fee and promote income.

Investment In Gramercy Capital Corp.

In May 2006, we purchased 750,000 shares of common stock of Gramercy for approximately $20.1 million in connection with its approximately $80.0 million common stock offering. At June 30, 2006, the book value of the Company’s investment in Gramercy totaled $116.8 million. Fees earned from various arrangements between the Company and Gramercy totaled approximately $5.4 million for the quarter ended June 30, 2006, including an incentive fee of $1.6 million earned as a result of Gramercy’s FFO exceeding the 9.5% annual return on equity performance threshold. For the six months ended June 30, 2006, the Company earned $10.2 million in fees from Gramercy. The Company’s share of FFO generated from its investment in Gramercy totaled approximately $3.7 million and $6.9 million for the three and six months ended June 30, 2006, respectively, compared to $2.2 million and $3.3 million for the same periods in the prior year.

The Company’s marketing, general and administrative, or MG&A, expenses include the consolidation of the expenses of its subsidiary GKK Manager LLC, the entity which manages and advises Gramercy. For the quarter ended June 30, 2006, the Company’s MG&A includes approximately $2.6 million of costs associated with Gramercy.
