SL Green Realty Corp.
Notes to Condensed Consolidated Financial Statements
(Unaudited)
March 31, 2007

1. Organization and Basis of Presentation

SL Green Realty Corp., also referred to as the Company or SL Green, a Maryland corporation, and SL Green Operating Partnership, L.P., or the operating partnership, a Delaware limited partnership, were formed in June 1997 for the purpose of combining the commercial real estate business of S.L. Green Properties, Inc. and its affiliated partnerships and entities. The operating partnership received a contribution of interest in the real estate properties, as well as 95% of the economic interest in the management, leasing and construction companies which are referred to as the Service Corporation. The Company has qualified, and expects to qualify in the current fiscal year, as a real estate investment trust, or REIT, under the Internal Revenue Code of 1986, as amended, or the Code, and operates as a self-administered, self-managed REIT. A REIT is a legal entity that holds real estate interests and, through payments of dividends to stockholders, is permitted to reduce or avoid the payment of Federal income taxes at the corporate level. Unless the context requires otherwise, all references to “we,” “our” and “us” means the Company and all entities owned or controlled by the Company, including the operating partnership.

Substantially all of our assets are held by, and our operations are conducted through, the operating partnership. The Company is the sole managing general partner of the operating partnership. As of March 31, 2007, minority investors held, in the aggregate, a 4.2% limited partnership interest in the operating partnership.

On January 25, 2007, we completed the acquisition, or the Reckson Merger, of all of the outstanding shares of common stock of Reckson Associates Realty Corp., or Reckson, pursuant to the terms of the Agreement and Plan of Merger, dated as of August 3, 2006, as amended, the Merger Agreement, among SL Green, Wyoming Acquisition Corp., or Wyoming, Wyoming Acquisition GP LLC, Wyoming Acquisition Partnership LP, Reckson and Reckson Operating Partnership, L.P., or ROP. Pursuant to the terms of the Merger Agreement, each of the issued and outstanding shares of common stock of Reckson were converted into (i) $31.68 in cash, (ii) 0.10387 of a share of the common stock, par value $0.01 per share, of SL Green and (iii) a prorated dividend in an amount equal to approximately $0.0977 in cash. We also assumed an aggregate of approximately $226.3 million of Reckson mortgage debt, approximately $287.5 million of Reckson convertible public debt and approximately $967.8 million of Reckson public unsecured notes. ROP is a subsidiary of our operating partnership.

On January 25, 2007, we completed the sale, or Asset Sale, of certain assets of ROP to an asset purchasing venture led by certain of Reckson’s former executive management, or the Buyer, for a total consideration of approximately $2.0 billion. SL Green caused ROP to transfer the following assets to the Buyer in the Asset Sale: (1) certain real property assets and/or entities owning such real property assets, in either case, of ROP and 100% of certain loans secured by real property, all of which are located in Long Island, New York; (2) certain real property assets and/or entities owning such real property assets, in either case, of ROP located in White Plains and Harrison, New York; (3) all of the real property assets and/or entities owning 100% of the interests in such real property assets, in either case, of ROP located in New Jersey; (4) the entity owning a 25% interest in Reckson Australia Operating Company LLC, Reckson’s Australian management company (including its Australian licensed responsible entity), and other related entities, and ROP and ROP subsidiaries’ rights to and interests in, all related contracts and assets, including, without limitation, property management and leasing, construction services and asset management contracts and services contracts; (5) the direct or indirect interest of Reckson in Reckson Asset Partners, LLC, an affiliate of RSVP and all of ROP’s rights in and to certain loans made by ROP to Frontline Capital Group, the bankrupt parent of RSVP, and other related entities, which will be purchased by a 50/50 joint venture with an affiliate of SL Green; (6) a 50% participation interest in certain loans made by a subsidiary of ROP that are secured by four real property assets located in Long Island, New York; and (7) 100% of certain loans secured by real property located in White Plains and New Rochelle, New York.

As of March 31, 2007, we owned the following interests in commercial office properties primarily in midtown Manhattan, a borough of New York City, or Manhattan, as well as Long Island City, Westchester County, Connecticut and New Jersey, which are collectively known as the Suburban assets:

Location	Ownership	Number of Properties	Square Feet	Weighted Average Occupancy (1)
Manhattan	Consolidated properties	26	14,145,000	98.2	%
	Unconsolidated properties	8	7,966,900	95.9	%

Suburban	Consolidated properties	28	4,660,900	90.5	%
	Unconsolidated properties	1	1,402,000	100.0	%
		63	28,174,800

(1) The weighted average occupancy represents the total leased square feet divided by total available square feet.

We also own an aggregate of 505,000 square feet of retail (nine) and development (one) properties. In addition, we manage three office properties owned by third parties and affiliated companies encompassing approximately 1.0 million rentable square feet.

We also own approximately 25% of the outstanding common stock of Gramercy Capital Corp. (NYSE: GKK), or Gramercy, as well as 64.83 units of the Class B limited partner interest in Gramercy’s operating partnership. See Note 6.

Partnership Agreement

In accordance with the partnership agreement of the Operating Partnership, or the Operating Partnership Agreement, we allocate all distributions and profits and losses in proportion to the percentage ownership interests of the respective partners. As the managing general partner of the Operating Partnership, we are required to take such reasonable efforts, as determined by us in our sole discretion, to cause the Operating Partnership to distribute sufficient amounts to enable the payment of sufficient dividends by us to avoid any Federal income or excise tax at the Company level. Under the Operating Partnership Agreement each limited partner will have the right to redeem units of limited partnership interest for cash, or if we so elect, shares of our common stock on a one-for-one basis. In addition, we are prohibited from selling 673 First Avenue and 470 Park Avenue South before August 2009.

Basis of Quarterly Presentation

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and notes required by accounting principles generally accepted in the United States for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for fair presentation have been included. The 2007 operating results for the period presented are not necessarily indicative of the results that may be expected for the year ending December 31, 2007. These financial statements should be read in conjunction with the financial statements and accompanying notes included in our annual report on Form 10-K for the year ended December 31, 2006.

The balance sheet at December 31, 2006 has been derived from the audited financial statements at that date but does not include all the information and footnotes required by accounting principles generally accepted in the United States for complete financial statements.

2. Significant Accounting Policies

Principles of Consolidation

The consolidated financial statements include our accounts and those of our subsidiaries, which are wholly-owned or controlled by us or entities which are variable interest entities in which we are the primary beneficiary under the Financial Accounting Standards Board, or FASB, Interpretation No. 46, or FIN 46, “Consolidation of Variable Interest Entities - an Interpretation of ARB No. 51,” and FIN 46, “Interpretation No. 46R, or FIN 46R.” See Note 5, Note 6 and Note 7. Entities which we do not control and entities which are variable interest entities, but where we are not the primary beneficiary are accounted for under the equity method. We consolidate variable interest entities in which we are determined to be the primary beneficiary. The interest that we do not own is included in “Minority Interest-Other Partnerships” on the balance sheet. All significant intercompany balances and transactions have been eliminated.

In June 2005, the FASB ratified the consensus in EITF Issue No. 04-5, or EITF 04-5, “Determining Whether a General Partner, or the General Partners as a Group, Controls a Limited Partnership or Similar Entity When the Limited Partners Have Certain Rights,” which provides guidance in determining whether a general partner controls a limited partnership. EITF 04-5 states that the general partner in a limited partnership is presumed to control that limited partnership. The presumption may be overcome if the limited partners have either (1) the substantive ability to dissolve the limited partnership or otherwise remove the general partner without cause or (2) substantive participating rights, which provide the limited partners with the ability to effectively participate in significant decisions that would be expected to be made in the ordinary course of the limited partnership’s business and thereby preclude the general partner from exercising unilateral control over the partnership. Our adoption of EITF 04-5 did not have any effect on net income or stockholders’ equity.

We consolidate our investment in 919 Third Avenue as we own a 51% controlling interest.

Investment in Commercial Real Estate Properties

In accordance with SFAS No. 141, “Business Combinations,” we allocate the purchase price of real estate to land and building and, if determined to be material, intangibles, such as the value of above, below and at-market leases and origination costs associated with the in-place leases. We depreciate the amount allocated to building and other intangible assets over their estimated useful lives, which generally range from three to 40 years. The values of the above and below market leases are amortized and recorded as either an increase (in the case of below market leases) or a decrease (in the case of above market leases) to rental income over the remaining

term of the associated lease. The value associated with in-place leases and tenant relationships are amortized over the expected term of the relationship, which includes an estimated probability of the lease renewal, and its estimated term. If a tenant vacates its space prior to the contractual termination of the lease and no rental payments are being made on the lease, any unamortized balance of the related intangible will be written off. The tenant improvements and origination costs are amortized as an expense over the remaining life of the lease (or charged against earnings if the lease is terminated prior to its contractual expiration date). We assess fair value of the leases based on estimated cash flow projections that utilize appropriate discount and capitalization rates and available market information. Estimates of future cash flows are based on a number of factors including the historical operating results, known trends, and market/economic conditions that may affect the property.

We have not yet obtained all the information necessary to finalize our estimates to complete the purchase price allocations in accordance with SFAS No. 141 related to the Reckson Merger. The purchase price allocations will be finalized once the information we identified has been received, which should not be longer than one year from the date of acquisition.

As a result of our evaluations, under SFAS No. 141, of acquisitions made, we recognized an increase of approximately $641,000 and $340,000 in rental revenue for the three months ended March 31, 2007 and 2006, respectively, for the amortization of below market leases and a reduction in lease origination costs, resulting from the reallocation of the purchase price of the applicable properties. We recognized a reduction in interest expense for the amortization of the above market rate debt of approximately $1.1 million and $189,000 for the three months ended March 31, 2007 and 2006, respectively.

Scheduled amortization on existing intangible liabilities on real estate investments is as follows (in thousands):

	Intangible Liabilities
2007	$	1,957
2008	2,605
2009	2,356
2010	1,857
2011	1,540
Thereafter	2,753
	$	13,068

Income Taxes

We are taxed as a REIT under Section 856(c) of the Code. As a REIT, we generally are not subject to Federal income tax. To maintain our qualification as a REIT, we must distribute at least 90% of our REIT taxable income to our stockholders and meet certain other requirements. If we fail to qualify as a REIT in any taxable year, we will be subject to Federal income tax on our taxable income at regular corporate rates. We may also be subject to certain state, local and franchise taxes. Under certain circumstances, Federal income and excise taxes may be due on our undistributed taxable income.

Pursuant to amendments to the Code that became effective January 1, 2001, we have elected or may elect to treat certain of our existing or newly created corporate subsidiaries as taxable REIT subsidiaries, or TRS. In general, a TRS of ours may perform non-customary services for our tenants, hold assets that we cannot hold directly and generally engage in any real estate or non-real estate related business. A TRS is subject to corporate Federal income tax. Our TRS’s generate income, resulting in Federal income tax liability for these entities. Our TRS’s paid approximately $1.5 million and $1.1 million in estimated federal, state and local taxes during the three months ended March 31, 2007 and 2006.

Stock-Based Employee Compensation Plans

We have a stock-based employee compensation plan, described more fully in Note 13. We account for this plan under SFAS No. 123 “Shared Based Payment,” revised, or SFAS No. 123-R.

The Black-Scholes option-pricing model was developed for use in estimating the fair value of traded options, which have no vesting restrictions and are fully transferable. In addition, option valuation models require the input of highly subjective assumptions including the expected stock price volatility. Because our plan has characteristics significantly different from those of traded options and because changes in the subjective input assumptions can materially affect the fair value estimate, in our opinion, the existing models do not necessarily provide a reliable single measure of the fair value of our employee stock options.

Compensation cost for stock options, if any, is recognized ratably over the vesting period of the award. Our policy is to grant options with an exercise price equal to the quoted closing market price of our stock on the grant date. Awards of stock, restricted stock or employee loans to purchase stock, which may be forgiven over a period of time, are expensed as compensation on a current basis over the benefit period.

The fair value of each stock option granted is estimated on the date of grant using the Black-Scholes option pricing model with the following weighted average assumptions for grants during the three months ended March 31, 2007 and 2006.

	2007		2006
Dividend yield	2.1	%	2.40	%
Expected life of option	5 years		5 years
Risk-free interest rate	4.61	%	4.80	%
Expected stock price volatility	21.48	%	16.61	%

The following table illustrates the effect on net income available to common stockholders and earnings per share if the fair value method had been applied to all outstanding and unvested stock options for the three months ended March 31, 2007 and 2006 (in thousands, except per share amounts):

	Three months Ended
	March 31,
	2007			2006
Net income available to common stockholders	$	147,427		$	23,732
Deduct stock option expense-all awards	(1,662		)	(492		)
Add back stock option expense included in net income	1,484			231
Allocation of compensation expense to minority interest	74			25
Pro forma net income available to common stockholders	$	147,323		$	23,496
Basic earnings per common share-historical	$	2.60		$	0.55
Basic earnings per common share-pro forma	$	2.60		$	0.54
Diluted earnings per common share-historical	$	2.53		$	0.54
Diluted earnings per common share-pro forma	$	2.53		$	0.53

The effects of applying SFAS No. 123-R in this pro forma disclosure are not indicative of the impact future awards may have on our results of operations.

Earnings Per Share

We present both basic and diluted earnings per share, or EPS. Basic EPS excludes dilution and is computed by dividing net income available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock, where such exercise or conversion would result in a lower EPS amount. This also includes units of limited partnership interest.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates.

Concentrations of Credit Risk

Financial instruments that potentially subject us to concentrations of credit risk consist primarily of cash investments, structured finance investments and accounts receivable. We place our cash investments in excess of insured amounts with high quality financial institutions. The collateral securing our structured finance investments is primarily located in the greater New York area. (See Note 5). We perform ongoing credit evaluations of our tenants and require certain tenants to provide security deposits or letters of credit. Though these security deposits and letters of credit are insufficient to meet the total value of a tenant’s lease obligation, they are a measure of good faith and a source of funds to offset the economic costs associated with lost rent and the costs associated with re-tenanting the space. Although the properties in our real estate portfolio are primarily located in Manhattan, we also have properties located in Westchester, Connecticut, New Jersey and Long Island. The tenants located in our buildings operate in various industries. Other than one tenant at 1515 Broadway who contributed approximately 6.4% of our annualized rent, no other tenant in the portfolio contributed more than 5.7% of our annualized rent, including our share of joint venture annualized rent, at March 31, 2007. Approximately 7%, 6%, 6% and 6% of our annualized rent, including our share of joint venture annualized rent, was attributable to 1221 Avenue of the Americas, 1515 Broadway, 420 Lexington Avenue and 1185 Avenue of the Americas, respectively, for the quarter ended March 31, 2007. One borrower accounted for more than 10.0% of the revenue earned on structured finance investments during the three months ended March 31, 2007.

Reclassification

Certain prior year balances have been reclassified to conform with the current year presentation.

New Accounting Pronouncements

In July 2006, the FASB issued Interpretation No. 48, “Accounting for Uncertainty in Income Taxes,” or FIN 48. This interpretation, among other things, creates a two-step approach for evaluating uncertain tax positions. Recognition (step one) occurs when an enterprise concludes that a tax position, based solely on its technical merits, is more-likely-than-not to be sustained upon examination. Measurement (step two) determines the amount of benefit that more-likely-than-not will be realized upon settlement. Derecognition of a tax position that was previously recognized would occur when a company subsequently determines that a tax position no longer meets the more-likely-than-not threshold of being sustained. FIN 48 specifically prohibits the use of a valuation allowance as a substitute for derecognition of tax positions, and it has expanded disclosure requirements. FIN 48 is effective for fiscal years beginning after December 15, 2006, in which the impact of adoption should be accounted for as a cumulative-effect adjustment to the beginning balance of retained earnings. The adoption of FIN 48, did not have a material impact on our consolidated financial statements.

3. Property Acquisitions

In January 2007, we acquired Reckson for approximately $6.0 billion, inclusive of transaction costs. Simultaneously, we sold approximately $2.0 billion of the Reckson assets to an asset purchasing venture led by certain of Reckson’s former executive management. The transaction included the acquisition of 30 properties encompassing approximately 9.2 million square feet, of which five properties encompassing approximately 4.2 million square feet are located in Manhattan.

In January 2007, we acquired 300 Main Street in Stamford, Connecticut and 399 Knollwood Road in White Plains, New York for approximately $46.6 million, from affiliates of RPW Group. These commercial office buildings encompass 275,000 square feet, inclusive of 50,000 square feet of garage parking at 300 Main Street.

In April 2007, we completed the acquisition of 331 Madison Avenue and 48 East 43rd Street for a total of $73.0 million. Both 331 Madison Avenue and 48 East 43rd Street are located adjacent to 317 Madison Avenue, a property that SL Green acquired in 2001. 331 Madison Avenue is an approximately 92,000-square foot, 14-story office building. The 22,850-square-foot 48 East 43rd Street property is a seven-story loft building that was later converted to office use.

In March 2007, we entered into an agreement to acquire an office property located at 500 West Putnam Avenue in Greenwich, Connecticut for $56.0 million. This property is a four-story, 121,500-square-foot office building. This transaction, which is subject to customary closing conditions, is expected to close during the second quarter of 2007. See Note 4 regarding the sale of 125 Broad Street in a related transaction.

In addition, we assumed approximately $136.9 million of structured finance investments as part of the Reckson Merger. There were approximately $205.0 million and none in repayments and participations during those periods, respectively. At March 31, 2007 and December 31, 2006 all loans were performing in accordance with the terms of the loan agreements.

(1)	Acquisition price represents the actual or implied purchase price for the joint venture.

(2)	We acquired our interest from The McGraw-Hill Companies, or MHC. MHC is a tenant at the property and accounted for approximately 14.8% of property’s annualized rent at March 31, 2007. We do not manage this joint venture.

(3)	As a result of exceeding the performance thresholds set forth in our joint venture agreement with SITQ, our economic stake in the property was increased to 66.175% in August 2006.

(4)	Under a tax protection agreement established to protect the limited partners of the partnership that transferred 1515 Broadway to the joint venture, the joint venture has agreed not to adversely affect the limited partners’ tax positions before December 2011. One tenant, whose leases end between 2008 and 2015, represents approximately 85.7% of this joint venture’s annualized rent at March 31, 2007.

(5)	In March 2006, we, along with Credit Suisse, sold a 40.0% interest in the joint venture to Schrager and RFR. They will perform the redevelopment and residential conversion of the Clock Tower. The arrangement provides Schrager and RFR with the ability to increase their ownership interest if certain performance thresholds are achieved.

(6)	We invested approximately $109.5 million in this asset through the origination of a loan secured by up to 47% of the interests in the property’s ownership, with an option to convert the loan to an equity interest. Certain existing members have the right to re-acquire approximately 4% of the property’s equity.

In March 2007, a joint venture between our company, SITQ and SEB Immobilier — Investment GmbH sold One Park Avenue for $550.0 million. We received approximately $108.7 million in proceeds from the sale, approximately $77.2 million of which represented an incentive distribution under our joint venture arrangement with SEB and the balance of approximately $31.5 million was recognized as gain on sale.

We finance our joint ventures with non-recourse debt. The first mortgage notes payable collateralized by the respective joint venture properties and assignment of leases at March 31, 2007 and December 31, 2006, respectively, are as follows (in thousands):

We are entitled to receive fees for providing management, leasing, construction supervision and asset management services to our joint ventures. We earned approximately $3.0 million and $1.5 million from these services for the three months ended March 31, 2007, and 2006, respectively. In addition, we have the ability to earn incentive fees based on the ultimate financial performance of certain of the joint venture properties.

Gramercy Capital Corp.

In April 2004, we formed Gramercy as a commercial real estate specialty finance company that focuses on the direct origination and acquisition of whole loans, subordinate interests in whole loans, mezzanine loans, preferred equity and net lease investments involving commercial properties throughout the United States. It also established a real estate securities business that will focus on the acquisition, trading and financing of commercial mortgage backed securities and other real estate related securities. Gramercy qualified as a REIT for federal income tax purposes and expects to qualify for its current fiscal year. In August 2004, Gramercy sold 12.5 million shares of common stock in its initial public offering at a price of $15.00 per share, for a total offering of $187.5 million. As part of the offering, which closed on August 2, 2004, we purchased 3,125,000 shares, or 25%, of Gramercy, for a total investment of approximately $46.9 million. During the term of Gramercy’s origination agreement, we will have the right to purchase 25% of the shares in any future offering of Gramercy’s common stock in order to maintain our percentage ownership interest in Gramercy. At March 31, 2007 we held 6,418,333 shares of Gramercy’s common stock representing a total investment of approximately $113.7 million. The market value of our investment in Gramercy was approximately $196.9 million at March 31, 2007.

Gramercy is a variable interest entity, but we are not the primary beneficiary. Due to the significant influence we have over Gramercy, we account for our investment under the equity method of accounting.

In connection with Gramercy’s initial public offering, GKK Manager LLC, or the Manager, an affiliate of ours, entered into a management agreement with Gramercy, which provided for an initial term through December 2007, with automatic one-year extension options and certain termination rights. In April 2006, Gramercy’s board of directors approved, among other things, an extension of the management

agreement through December 2009. Gramercy pays the Manager an annual management fee equal to 1.75% of their gross stockholders’ equity (as defined in the amended and restated management agreement). In addition, Gramercy also pays the Manager a collateral management fee (as defined in the collateral management agreement) of 0.25% per annum on the outstanding investment grade bonds in Gramercy’s July 2005 collateralized debt obligation. The amended and restated management agreement provides that in connection with formations of future collateralized debt obligations, or CDO, or other securitization vehicles, if a collateral manager is retained, the Manager or an affiliate will be the collateral manager and will receive the following fees: (i) 0.25% per annum of the book value of the assets owned for transitional “managed” CDOs, (ii) 0.15% per annum of the book value of the assets owned for non-transitional “managed” CDOs, (iii) 0.10% per annum of the book value of the assets owned for static CDOs that own primarily non-investment grade bonds, and (iv) 0.05% per annum of the book value of the assets owned for static CDOs that own primarily investment grade bonds; limited in each instance by the fees that are paid to the collateral manager. For the three months ended March 31, 2007 and 2006, we received an aggregate of approximately $2.7 million and $2.2 million, respectively, in fees under the management agreement and $1.1 million and $0.5 million under the collateral management agreement.

To provide an incentive for the Manager to enhance the value of Gramercy’s common stock, we, along with the other holders of Class B limited partnership interests in Gramercy’s operating partnership, are entitled to an incentive return payable through the Class B limited partner interests in Gramercy’s operating partnership, equal to 25% of the amount by which funds from operations (as defined in Gramercy’s partnership agreement) plus certain accounting gains exceed the product of the weighted average stockholders’ equity of Gramercy multiplied by 9.5% (divided by 4 to adjust for quarterly calculations). We will record any distributions on the Class B limited partner interests as incentive distribution income in the period when earned and when receipt of such amounts have become probable and reasonably estimable in accordance with Gramercy’s partnership agreement as if such agreement had been terminated on that date. We earned approximately $2.8 million and $1.2 million under this agreement for the three months ended March 31, 2007, and 2006, respectively. Due to the control we have over the Manager, we consolidate the accounts of the Manager into ours.

In May 2005, our Compensation Committee approved long-term incentive performance awards pursuant to which certain of our officers and employees, including some of whom are our senior executive officers, were awarded a portion of the interests previously held by us in the Manager as well as in the Class B limited partner interests in Gramercy’s operating partnership. These awards are dependent upon, among other things, tenure of employment and the performance by SL Green Realty Corp. of its investment in Gramercy. We recorded compensation expense of approximately $0.7 million and $0.3 million for the three months ended March 31, 2007 and 2006, respectively, related to these awards. After giving effect to these awards, we own 64.83 units of the Class B limited partner interests and 65.83% of the Manager. The officers and employees who received these awards own 15.75 units of the Class B limited partner interests and 15.75% of the Manager.

Gramercy is obligated to reimburse the Manager for its costs incurred under an asset servicing agreement and an outsource agreement between the Manager and us. The asset servicing agreement, which was amended and restated in April 2006, provides for an annual fee payable to us of 0.05% of the book value of all Gramercy’s credit tenant lease assets and non-investment grade bonds and 0.15% of the book value of all other Gramercy assets. We may reduce the asset-servicing fee for fees that Gramercy pays directly to outside servicers. The outsourcing agreement currently provides for a fee of $1.33 million per year, increasing 3% annually over the prior year. For the three months ended March 31, 2007 and 2006, the Manager received an aggregate of approximately $1.1 million and $0.8 million, respectively, under the outsourcing and asset servicing agreements.

During the three months ended March 31, 2006, we paid our proportionate share of an advisory fee of approximately $162,500 to Gramercy in connection with a transaction.

All fees earned from Gramercy are included in other income in the Consolidated Statements of Income.

Effective May 1, 2005 Gramercy entered into a lease agreement with an affiliate of ours, for their corporate offices at 420 Lexington Avenue, New York, NY. The lease is for approximately five thousand square feet with an option to lease an additional approximately two thousand square feet and carries a term of ten year with rents of approximately $249,000 per annum for year one rising to $315,000 per annum in year ten.

7. Investment in and Advances to Affiliates

Service Corporation

Income from management, leasing and construction contracts from third parties and joint venture properties is realized by the Service Corporation. In order to maintain our qualification as a REIT, we, through our operating partnership, own 100% of the non-voting common stock (representing 95% of the total equity) of the Service Corporation our operating partnership receives substantially all of the cash flow from the Service Corporation’s operations through dividends on its equity interest. All of the voting common stock of the Service Corporation (representing 5% of the total equity) is held by our affiliate. This controlling interest gives the affiliate the power to elect all directors of the Service Corporation. Effective July 1, 2003, we consolidated the operations of the Service Corporation because it is considered to be a variable interest entity under FIN 46 and we are the primary beneficiary. For the three months ended March 31, 2007 and 2006, the Service Corporation earned approximately $3.5 million and $1.3 million of revenue and incurred approximately $2.6 million and $1.9 million in expenses, respectively. Effective January 1, 2001, the Service Corporation elected to be treated as a TRS.

All of the management, leasing and construction services with respect to the properties wholly-owned by us are conducted through SL Green Management LLC which is 100% owned by our Operating Partnership.

eEmerge

In May 2000, our operating partnership formed eEmerge, Inc., a Delaware corporation, or eEmerge. eEmerge is a separately managed, self-funded company that provides fully-wired and furnished office space, services and support to businesses.

In March 2002, we acquired all the voting common stock of eEmerge Inc. As a result, we control all the common stock of eEmerge. Effective with the quarter ended March 31, 2002, we consolidated the operations of eEmerge. Effective January 1, 2001, eEmerge elected to be taxed as a TRS.

In June 2000, eEmerge and Eureka Broadband Corporation, or Eureka, formed eEmerge.NYC LLC, a Delaware limited liability company, or ENYC, whereby eEmerge has a 95% interest and Eureka has a 5% interest in ENYC. During the third quarter of 2006, ENYC acquired the interest held by Eureka. As a result, eEmerge owns 100% of ENYC. ENYC operates a 71,700 square foot fractional office suites business. ENYC entered into a 10-year lease with our Operating Partnership for its 50,200 square foot premises, which is located at 440 Ninth Avenue, Manhattan. ENYC entered into another 10-year lease with our Operating Partnership for its 21,500 square foot premises at 28 West 44PthP Street, Manhattan. Allocations of net profits, net losses and distributions are made in accordance with the Limited Liability Company Agreement of ENYC. Effective with the quarter ended March 31, 2002, we consolidated the operations of ENYC.

(1) Held in bankruptcy remote special purpose entity.

(2) Effective interest rate for the quarter ended March 31, 2007.

(3) The balance on this mortgage at March 31, 2007 was included in liabilities related to assets held for sale.

(4) We own a 51% interest in the joint venture that is the borrower on this loan. This loan is non-recourse to us.

(5) This loan will be repaid in May 2007.

(6) We sold this property in March 2007.

(7) We own a 50% interest in the joint venture that is the borrower on these loans. These loans are non-recourse to us.

(8) See Note 3 for a description of our ownership interest in this property.

At March 31, 2007 and December 31, 2006 the gross book value of the properties collateralizing the mortgage notes was approximately $3.2 billion and $1.6 billion, respectively.

For the three months ended March 31, 2007 and 2006, we incurred approximately $60.9 million and $18.2 million of interest expense, respectively, excluding interest which was capitalized of approximately $3.9 million and $2.5 million, respectively.

Mortgage Recording Tax - Hypothecated Loan

We had a credit loan totaling approximately $250.0 million from Wachovia Bank, National Association (“Wachovia”) at December 31, 2006. This loan was collateralized by the mortgage encumbering our interest in 485 Lexington Avenue. The loan was also collateralized by an equivalent amount of our cash, which was held by Wachovia and invested in US Treasury securities. Interest earned on the cash collateral was applied by Wachovia to service the loan with interest rates commensurate with that of a portfolio of six-month US Treasury securities. We, along with Wachovia, each had the right of offset and, therefore, the loan and the cash collateral were presented on a net basis in the consolidated balance sheet at December 31, 2006. The purpose of this loan was to preserve mortgage recording tax credits for future potential refinancing for which these credits would be applicable. At the same time, the underlying mortgage remains a bona-fide debt to Wachovia. On January 22, 2007, we refinanced 485 Lexington Avenue at which time this mortgage was assigned to the new lender and we repaid an equivalent amount of the loan.

10. Corporate Indebtedness

2005 Unsecured Revolving Credit Facility

We have a $800.0 million unsecured revolving credit facility. We increased the capacity under the 2005 unsecured revolving credit facility from $500.0 million in January 2007. The 2005 unsecured revolving credit facility bears interest at a spread ranging from 85 basis points to 125 basis points over LIBOR, based on our leverage ratio. This facility matures in September 2008 and has a one-year extension option. The 2005 unsecured revolving credit facility also requires a 12.5 to 25 basis point fee on the unused balance payable annually in arrears. The 2005 unsecured revolving credit facility had no balance and carried a spread over LIBOR of 110 basis points at March 31, 2007. Availability under the 2005 unsecured revolving credit facility was further reduced by the issuance of approximately $15.3 million in letters of credit. The effective all-in interest rate on the 2005 unsecured revolving credit facility was 6.42% for the three months ended March 31, 2007. The 2005 unsecured revolving credit facility includes certain restrictions and covenants (see restrictive covenants below).

Term Loans

We had a $325.0 million unsecured term loan, which was scheduled to mature in August 2009. This term loan bore interest at a spread ranging from 110 basis points to 140 basis points over LIBOR, based on our leverage ratio. This unsecured term loan was repaid and terminated in March 2007. The effective all-in interest rate on the unsecured term loan was 5.63% for the three months ended March 31, 2007.

We have a $200.0 million five-year non-recourse term loan secured by a pledge of our ownership interest in 1221 Avenue of the Americas. This term loan has a floating rate of 125 basis points over the current LIBOR rate and matures in May 2010. The effective all-in interest rate on this secured term loan was 5.96% for the three months ended March 31, 2007.

In January 2007, we closed on a $500.0 million unsecured bridge loan, which matures in January 2010. This term loan bears interest at a spread ranging from 85 basis points to 125 basis points over LIBOR, based on our leverage ratio. As of March 31, 2007, we had $500.0 million outstanding under the unsecured bridge loan at the rate of 110 basis points over LIBOR. This bridge loan is prepayable at any time without penalty. The effective all-in interest rate on the unsecured bridge loan was 6.42% for three months ended March 31, 2007. The unsecured bridge loan includes certain restrictions and covenants (see restrictive covenants below).

Unsecured Notes

In March 2007, we issued $750.0 million of 3.00% exchangeable senior notes which are due in 2027. The notes were offered in accordance with Rule 144A under the Securities Act of 1933, as amended. The notes will pay interest semi-annually at a rate of 3.00% per annum and mature on March 30, 2027. Interest on these notes is payable semi-annually on March 30 and September 30. The notes will have an initial exchange rate representing an exchange price that is at a 25.0% premium to the last reported sale price of our common stock on March 20, 2007, or $173.30. The initial exchange rate is subject to adjustment under certain circumstances. The notes will be senior unsecured obligations of our operating partnership and will be exchangeable upon the occurrence of specified events, and during the period beginning on the twenty-second scheduled trading day prior to the maturity date and ending on the second business day prior to the maturity date, into cash or a combination of cash and shares of our common stock, if any, at our option. The notes will be Redeemable, at our option on, and after April 15, 2012. We may be required to repurchase the notes on March 30, 2012, 2017 and 2022, and upon the occurrence of certain designated events. The net proceeds from the offering were approximately $736.0 million, after deducting estimated fees and expenses. The proceeds of the offering were used to repay certain of our existing indebtedness, make investments in additional properties, and make open market purchases of our common stock and for general corporate purposes.

As of March 31, 2007, we had outstanding approximately $2.0 billion (net of unamortized issuance discounts) of senior unsecured notes.

The following table sets forth our senior unsecured notes and other related disclosures by scheduled maturity date (in thousands):

(a) These notes were redeemed on April 27, 2007.

(b) Exchangeable senior debentures which are callable after June 17, 2010 at 100% of par. In addition, the debentures can be put to us, at the option of the holder at par plus accrued and unpaid interest, on June 15, 2010, 2015 and 2020 and upon the occurrence of certain change of control transactions. As a result of the Reckson Merger, the adjusted exchange rate for the debentures is 7.7461 shares of our common stock per $1,000 of principal amount of debentures and the adjusted reference dividend for the debentures is $1.3491.

Interest on the senior unsecured notes is payable semi-annually with principal and unpaid interest due on the scheduled maturity dates. In addition, certain of the senior unsecured notes were issued at discounts aggregating approximately $20.1 million. Such discounts are being amortized to interest expense over the term of the senior unsecured notes to which they relate. Through March 31, 2007, approximately $0.4 million of the aggregate discounts have been amortized.

Restrictive Covenants

The terms of the 2005 unsecured revolving credit facility and the unsecured bridge loan and unsecured bonds include certain restrictions and covenants which limit, among other things, the payment of dividends (as discussed below), the incurrence of additional indebtedness, the incurrence of liens and the disposition of assets, and which require compliance with financial ratios relating to the minimum amount of tangible net worth, the minimum amount of debt service coverage, and fixed charge coverage, the maximum amount of unsecured indebtedness, the minimum amount of unencumbered property debt service coverage and certain investment limitations. The dividend restriction referred to above provides that, except to enable us to continue to qualify as a REIT for Federal Income Tax purposes, we will not during any four consecutive fiscal quarters make distributions with respect to common stock or other equity interests in an aggregate amount in excess of 90% of funds from operations for such period, subject to certain other adjustments. As of March 31, 2007 and December 31, 2006, we were in compliance with all such covenants.

Junior Subordinate Deferrable Interest Debentures

In June 2005, we issued $100.0 million in unsecured floating rate trust preferred securities through a newly formed trust, SL Green Capital Trust I, or Trust, which is a wholly-owned subsidiary of our Operating Partnership. The securities mature in 2035 and bear interest at a fixed rate of 5.61% for the first ten years ending July 2015, a period of up to eight consecutive quarters if our Operating Partnership exercises its right to defer such payments. The trust preferred securities are redeemable, at the option of our Operating Partnership, in whole or in part, with no prepayment premium any time after July 2010. Our interest in the Trust is accounted for using the equity method and the assets and liabilities of that entity is not consolidated into our financial statements. Interest on the junior subordinated notes is included in interest expense on our consolidated statements of income while the value of the junior subordinated notes, net of our investment in the trusts that issued the securities, is presented as a separate item in our consolidated balance sheets.

The operating partnership is the lessor and the sublessor to tenants under operating leases with expiration dates ranging from March 31, 2007 to 2037. The minimum rental amounts due under the leases are generally either subject to scheduled fixed increases or adjustments. The leases generally also require that the tenants reimburse us for increases in certain operating costs and real estate taxes above their base year costs.

In 2007, we paid a consulting fee of $525,000 to Stephen Wolff, the brother-in-law of Marc Holliday, in connection with our aggregate investment of $119.1 million in the joint venture that owns 800 Third Avenue.

Management Fees

S.L. Green Management Corp. receives property management fees from an entity in which Stephen L. Green owns an interest. The aggregate amount of fees paid to S.L. Green Management Corp. from such entity was approximately $66,000 and $43,000 for the three months ended March 31, 2007 and 2006, respectively.

Management Indebtedness

In January 2001, Mr. Marc Holliday, then our president, received a non-recourse loan from us in the principal amount of $1.0 million pursuant to his amended and restated employment and non-competition agreement he executed at the time. This loan bore interest at the applicable federal rate per annum and was secured by a pledge of certain of Mr. Holliday’s shares of our common stock. The principal of and interest on this loan was forgivable upon our attainment of specified financial performance goals prior to December 31, 2006, provided that Mr. Holliday remained employed by us until January 17, 2007. Due to the attainment of the performance goals, this loan was forgiven in January 2007. In April 2000, Mr. Holliday received a loan from us in the principal amount of $300,000 with a maturity date of July 2003. This loan bore interest at a rate of 6.60% per annum and was secured by a pledge of certain of Mr. Holliday’s shares of our common stock. In May 2002, Mr. Holliday entered into a loan modification agreement with us in order to modify the repayment terms of the $300,000 loan. Pursuant to the agreement, $100,000 (plus accrued interest thereon) was forgivable on each of January 1, 2004, January 1, 2005 and January 1, 2006, provided that Mr. Holliday remained employed by us through each of such date. This $300,000 loan was completely forgiven on January 1, 2006.

13. Stockholders’ Equity

Common Stock

Our authorized capital stock consists of 200,000,000 shares, $.01 par value, of which we have authorized the issuance of up to 100,000,000 shares of common stock, $.01 par value per share, 75,000,000 shares of excess stock, at $.01 par value per share, and 25,000,000 shares of preferred stock, par value $.01 per share. As of March 31, 2007, 59,181,651 shares of common stock and no shares of excess stock were issued and outstanding.

In January 2007, we issued approximately 9.0 million shares of our common stock in connection with the Reckson acquisition. These shares had a value of approximately $1.1 billion on the date the merger agreement was executed.

In March 2007, Board of Directors approved a stock purchase plan under which we can buy up to $300.0 million of our common stock. This plan will expire on December 31, 2008. In April 2007, we purchased approximately 16,000 shares of our common stock at an average price of $132.48 per share.

Perpetual Preferred Stock

In December 2003, we sold 6,300,000 shares of our 7.625% Series C preferred stock, (including the underwriters’ over-allotment option of 700,000 shares) with a mandatory liquidation preference of $25.00 per share. Net proceeds from this offering (approximately $152.0 million) were used principally to repay amounts outstanding under our secured and unsecured revolving credit facilities. The Series C preferred stockholders receive annual dividends of $1.90625 per share paid on a quarterly basis and dividends are cumulative, subject to certain provisions. On or after December 12, 2008, we may redeem the Series C preferred stock at par for cash at our option. The Series C preferred stock was recorded net of underwriters discount and issuance costs.

In 2004, we sold 4,000,000 shares of our 7.875% Series D cumulative redeemable preferred stock, or the Series D preferred stock, with a mandatory liquidation preference of $25.00 per share. Net proceeds from these offerings (approximately $96.3 million) were used principally to repay amounts outstanding under our secured and unsecured revolving credit facilities. The Series D preferred stockholders receive annual dividends of $1.96875 per share paid on a quarterly basis and dividends are cumulative, subject to certain provisions. On or after May 27, 2009, we may redeem the Series D preferred stock at par for cash at our option. The Series D preferred stock was recorded net of underwriters discount and issuance costs.

Rights Plan

In February 2000, our board of directors authorized a distribution of one preferred share purchase right, or Right, for each outstanding share of common stock under a shareholder rights plan. This distribution was made to all holders of record of the common stock on March 31, 2000. Each Right entitles the registered holder to purchase from us one one-hundredth of a share of Series B junior participating preferred stock, par value $0.01 per share, or Preferred Shares, at a price of $60.00 per one one-hundredth of a Preferred Share, or Purchase Price, subject to adjustment as provided in the rights agreement. The Rights expire on March 5, 2010, unless we extend the expiration date or the Right is redeemed or exchanged earlier. The Rights are attached to each share of common stock. The Rights are generally exercisable only if a person or group becomes the beneficial owner of 17% or more of the outstanding common stock or announces a tender offer for 17% or more of the outstanding common stock, or Acquiring Person. In the event that a person or group becomes an Acquiring Person, each holder of a Right, excluding the Acquiring Person, will have the right to receive, upon exercise, common stock having a market value equal to two times the Purchase Price of the Preferred Shares.

Dividend Reinvestment and Stock Purchase Plan

We filed a registration statement with the SEC for our dividend reinvestment and stock purchase plan, or DRIP, which was declared effective on September 10, 2001, and commenced on September 24, 2001. We registered 3,000,000 shares of our common stock under the DRIP.

During the three months ended March 31, 2007 and 2006, approximately 17,000 and 43,000 shares were issued and approximately $2.3 million and $3.4 million of proceeds were received, respectively, from dividend reinvestments and/or stock purchases under the DRIP. DRIP shares may be issued at a discount to the market price.

2003 Long-Term Outperformance Compensation Program

Our board of directors adopted a long-term, seven-year compensation program for senior management. The program, which measured our performance over a 48-month period (unless terminated earlier) commencing April 1, 2003, provided that holders of our common equity were to achieve a 40% total return during the measurement period over a base of $30.07 per share before any restricted stock awards were granted. Plan participants would receive an award of restricted stock in an amount between 8% and 10% of the excess return over the baseline return. At the end of the four-year measurement period, 40% of the award will vest on the measurement date and 60% of the award will vest ratably over the subsequent three years based on continued employment. Any restricted stock to be issued under the program will be allocated from our 2005 Stock Option and Incentive Plan (as defined below), which was previously approved through a stockholder vote in May 2002. In April 2007, the Compensation Committee determined that under the terms of the 2003 Outperformance Plan, as of March 31, 2007, the performance hurdles had been met and the maximum performance pool of $22,825,000, taking into account forfeitures, was established. In connection with this event, approximately 166,312 shares of restricted stock (as adjusted for forfeitures) were allocated under the 2005 Stock Option and Incentive Plan. These awards are subject to vesting as noted above. We record the expense of the restricted stock award in accordance with SFAS 123-R. The fair value of the award on the date of grant was determined to be $3.2 million. Forty percent of the value of the award will be amortized over four years and the balance will be amortized at 20% per year over five, six and seven years, respectively, such that 20% of year five, 16.67% of year six, and 14.29% of year seven will be recorded in year one. Compensation expense of $101,500 and $162,500 was recorded during the three months ended March 31, 2007 and 2006, respectively.

2005 Long-Term Outperformance Compensation Program

In December 2005, the compensation committee of our board of directors approved a long-term incentive compensation program, the 2005 Outperformance Plan. Participants in the 2005 Outperformance Plan will share in a “performance pool” if our total return to stockholders for the period from December 1, 2005 through November 30, 2008 exceeds a cumulative total return to stockholders of 30% during the measurement period over a base share price of $68.51 per share. The size of the pool was to be 10% of the outperformance amount in excess of the 30% benchmark, subject to a maximum dilution cap equal to the lesser of 3% of our outstanding shares and units of limited partnership interest as of December 1, 2005 or $50.0 million. In the event the potential performance pool reached this dilution cap before November 30, 2008 and remained at that level or higher for 30 consecutive days, the performance period was to end early and the pool would be formed on the last day of such 30 day period. Each participant’s award under the 2005 Outperformance Plan would be designated as a specified percentage of the aggregate performance pool to be allocated to him or her assuming the 30% benchmark is achieved. Individual awards would be made in the form of partnership units, or LTIP Units, that may ultimately become exchangeable for shares of our common stock or cash, at our election. LTIP Units would be granted prior to the determination of the performance pool; however, they were only to vest upon satisfaction of performance and other thresholds, and were not entitled to distributions until after the performance pool was established. The 2005 Outperformance Plan provides that if the pool was established, each participant would also be entitled to the distributions that would have been paid on the number of LTIP Units earned, had they been issued at the beginning of the performance period. Those distributions were to be paid in the form of additional LTIP Units.

After the performance pool was established, the earned LTIP Units are to receive regular quarterly distributions on a per unit basis equal to the dividends per share paid on our common stock, whether or not they are vested. Any LTIP Units not earned upon the establishment of the performance pool were to be automatically forfeited, and the LTIP Units that are earned are subject to time-based vesting, with one-third of the LTIP Units earned vesting on November 30, 2008 and each of the first two anniversaries thereafter based on continued employment. On June 14, 2006, the Compensation Committee determined that under the terms of the 2005 Outperformance Plan, as of June 8, 2006, the performance period had accelerated and the maximum performance pool of $49,250,000, taking into account forfeitures, was established. Individual awards under the 2005 Outperformance Plan are in the form of partnership units, or LTIP Units, in SL Green Operating Partnership, L.P., that, subject to certain conditions, are convertible into shares of the Company’s common stock or cash, at the Company’s election. The total number of LTIP Units earned by all participants as a result of the establishment of the performance pool was 490,475 and are subject to time-based vesting.

The cost of the 2005 Outperformance Plan (approximately $8.0 million, subject to adjustment for forfeitures) will continue to be amortized into earnings through the final vesting period in accordance with SFAS 123-R. We recorded approximately $0.5 million and $0.4 million of compensation expense during the three months ended March 31, 2007 and 2006, respectively, in connection with the 2005 Outperformance Plan.

2006 Long-Term Outperformance Compensation Program

On August 14, 2006, the compensation committee of our board of directors approved a long-term incentive compensation program, the 2006 Outperformance Plan. Participants in the 2006 Outperformance Plan will share in a “performance pool” if our total return to stockholders for the period from August 1, 2006 through July 31, 2009 exceeds a cumulative total return to stockholders of 30% during the measurement period over a base share price of $106.39 per share. The size of the pool will be 10% of the outperformance amount in excess of the 30% benchmark, subject to a maximum award of $60 million. The maximum award will be reduced by the amount of any unallocated or forfeited awards. In the event the potential performance pool reaches the maximum award before July 31, 2009 and remains at that level or higher for 30 consecutive days, the performance period will end early and the pool will be formed on the last day of such 30 day period. Each participant’s award under the 2006 Outperformance Plan will be designated as a specified percentage of the aggregate performance pool. Assuming the 30% benchmark is achieved, the pool will be allocated among the participants in accordance with the percentage specified in each participant’s participation agreement. Individual awards will be made in the form of partnership units, or LTIP Units, that, subject to vesting and the satisfaction of other conditions, are exchangeable for a per unit value equal to the then trading price of one share of our common stock. This value is payable in cash or, at our election, in shares of common stock. LTIP Units will be granted prior to the determination of the performance pool; however, they will only vest upon satisfaction of performance and time vesting thresholds under the 2006 Outperformance Plan, and will not be entitled to distributions until after the performance pool is established. Distributions on LTIP Units will equal the dividends paid on our common stock on a per unit basis. The 2006 Outperformance Plan provides that if the pool is established, each participant will also be entitled to the distributions that would have been paid had the number of earned LTIP Units been issued at the beginning of the performance period. Those distributions will be paid in the form of additional LTIP Units. Thereafter, distributions will be paid currently with respect to all earned LTIP Units that are a part of the performance pool, whether vested or unvested. Although the amount of earned awards under the 2006 Outperformance Plan (i.e. the number of LTIP Units earned) will be determined when the performance pool is established, not all of the awards will vest at that time. Instead, one-third of the awards will vest on July 31, 2009 and each of the first two anniversaries thereafter based on continued employment.

In the event of a change in control of our company prior to August 1, 2007, the performance period will be shortened to end on a date immediately prior to such event and the cumulative stockholder return benchmark will be adjusted on a pro rata basis. In the event of a change in control of our company on or after August 1, 2007 but before July 31, 2009, the performance pool will be calculated assuming the performance period ended on July 31, 2009 and the total return continued at the same annualized rate from the date of the change in control to July 31, 2009 as was achieved from August 1, 2006 to the date of the change in control; provided that the performance pool may not exceed 200% of what it would have been if it was calculated using the total return from August 1, 2006 to the date of the change in control and a pro rated benchmark. In either case, the performance pool will be formed as described above if the adjusted benchmark target is achieved and all earned awards will be fully vested upon the change in control. If a change in control occurs after the performance period has ended, all unvested awards issued under our 2006 Outperformance Plan will become fully vested upon the change in control.

The cost of the 2006 Outperformance Plan will be amortized into earnings through the final vesting period in accordance with SFAS 123-R. We recorded approximately $0.6 million of compensation expense during the three months ended March 31, 2007 in connection with the 2006 Outperformance Plan.

Deferred Stock Compensation Plan for Directors

Under our Independent Director’s Deferral Program, which commenced July 2004, our non-employee directors may elect to defer up to 100% of their annual retainer fee, chairman fees and meeting fees. Unless otherwise elected by a participant, fees deferred under the program shall be credited in the form of phantom stock units. The phantom stock units are convertible into an equal number of shares of common stock upon such directors’ termination of service from the Board of Directors or a change in control by us, as defined by the program. Phantom stock units are credited to each non-employee director quarterly using the closing price of our common stock on the applicable dividend record date for the respective quarter. Each participating non-employee director’s account is also credited for an equivalent amount of phantom stock units based on the dividend rate for each quarter.

During the three months ended March 31, 2007, 3,567 phantom stock units were earned. As of March 31, 2007, there were approximately 14,127 phantom stock units outstanding.

Stock Option Plan

During August 1997, we instituted the 1997 Stock Option and Incentive Plan, or the 1997 Plan. The 1997 Plan was amended in December 1997, March 1998, March 1999 and May 2002. The 1997 Plan, as amended, authorizes (i) the grant of stock options that qualify as incentive stock options under Section 422 of the Code, or ISOs, (ii) the grant of stock options that do not qualify, or NQSOs, (iii) the grant of stock options in lieu of cash Directors’ fees and (iv) grants of shares of restricted and unrestricted common stock. The exercise price of stock options are determined by our compensation committee, but may not be less than 100% of the fair market value of the shares of our common stock on the date of grant. At March 31, 2007, approximately 0.7 million shares of our common stock were reserved for issuance under the 1997 Plan.

2005 Stock Option and Incentive Plan

Subject to adjustments upon certain corporate transactions or events, up to a maximum of 3,500,000 shares, or the Fungible Pool Limit, may be granted as Options, Restricted Stock, Phantom Shares, dividend equivalent rights and other equity-based awards under the 2005 Plan; provided that, as described below, the manner in which the Fungible Pool Limit is finally determined can ultimately result in the issuance under the 2005 Plan of up to 4,375,000 shares (subject to adjustments upon certain corporate transactions or events). Each share issued or to be issued in connection with ‘‘Full-Value Awards’’ (as defined below) that vest or are granted based on the achievement of certain performance goals that are based on (A) FFO growth, (B) total return to stockholders (either in absolute terms or compared with other companies in the market) or (C) a combination of the foregoing (as set forth in the 2005 Plan), shall be counted against the Fungible Pool Limit as 2.6 units. “Full-Value Awards” are awards other than Options, Stock Appreciation Rights or other awards that do not deliver the full value at grant thereof of the underlying shares (e.g., Restricted Stock). Each share issued or to be issued in connection with any other Full-Value Awards shall be counted against the Fungible Pool Limit as 3.9 units. Options, Stock Appreciation Rights and other awards that do not deliver the value at grant thereof of the underlying shares and that expire 10 years from the date of grant shall be counted against the Fungible Pool Limit as one unit. Options, Stock Appreciation Rights and other awards that do not deliver the value at grant thereof of the underlying shares and that expire five years from the date of grant shall be counted against the Fungible Pool Limit as 0.8 of a unit, or five-year option. Thus, under the foregoing rules, depending on the type of grants made, as many as 4,375,000 shares can be the subject of grants under the 2005 Plan. At the end of the third calendar year following the effective date of the 2005 Plan, (i) the three-year average of (A) the number of shares subject to awards granted in a single year, divided by (B) the number of shares of our outstanding common stock at the end of such year shall not exceed the (ii) greater of (A) 2% or (B) the mean of the applicable peer group. For purposes of calculating the number of shares granted in a year in connection with the limitation set forth in the foregoing sentence, shares underlying Full-Value Awards will be taken into account as (i) 1.5 shares if our annual common stock price volatility is 53% or higher, (ii) two shares if our annual common stock price volatility is between 25% and 52%, and (iii) four shares if our annual common stock price volatility is less than 25%. No award may be granted to any person who, assuming exercise of all options and payment of all awards held by such person, would own or be deemed to own more than 9.8% of the outstanding shares of the Company’s common stock. In addition, subject to adjustment upon certain corporate transactions or events, a participant may not receive awards (with shares subject to awards being counted, depending on the type of award, in the proportions ranging from 0.8 to 3.9, as described above) in any one year covering more than 700,000 shares; thus, under this provision, depending on the type of grant involved, as many as 875,000 shares can be the subject of option grants to any one person in any year, and as many as 269,230 shares may be granted as restricted stock (or be the subject of other Full-Value Grants) to any one person in any year. If an option or other award granted under the 2005 Plan expires or terminates, the common stock subject to any portion of the award that expires or terminates without having been exercised or paid, as the case may be, will again become available for the issuance of additional awards. Shares of our common stock distributed under the 2005 Plan may be treasury shares or authorized but unissued shares. Unless the 2005 Plan is previously terminated by the Board, no new Award may be granted under the 2005 Plan after the tenth anniversary of the date that such 2005 Plan was initially approved by the Board. At March 31, 2007, approximately 2.0 million shares of our common stock, calculated on a weighted basis, were available for issuance under the 2005 Plan, or 2.5 million if all shares available under the 2005 Plan were issued as five-year options.

In March 2007, our Board of Directors approved an amended and restated 2005 Stock Option and Incentive Plan that would increase the number of shares that may be issued pursuant to such plan. The amended and restated 2005 Stock Option and Incentive Plan is subject to stockholder approval.

Options granted under the plans are exercisable at the fair market value on the date of grant and, subject to termination of employment, generally expire ten years from the date of grant, are not transferable other than on death, and are generally exercisable in three to five annual installments commencing one year from the date of grant.

A summary of the status of our stock options as of March 31, 2007 and December 31, 2006 and changes during the periods then ended are presented below:

The unit holders represent the minority interest ownership in our operating partnership. As of March 31, 2007 and December 31, 2006, the minority interest unit holders owned 4.2% (2,618,700 units) and 5.1% (2,693,900 units) of the operating partnership, respectively. At March 31, 2007, 2,618,700 shares of our common stock were reserved for the conversion of units of limited partnership interest in our operating partnership.

15. Commitments and Contingencies

We and our operating partnership are not presently involved in any material litigation nor, to our knowledge, is any material litigation threatened against us or our properties, other than routine litigation arising in the ordinary course of business. Management believes the costs, if any, incurred by us and our operating partnership related to this litigation will not materially affect our financial position, operating results or liquidity.

Our property located at 810 7th Avenue, New York, NY is subject to certain air rights lease agreements. These lease agreements have terms expiring in 2044 and 2048, including renewal options.

16. Financial Instruments: Derivatives and Hedging

In accordance with SFAS No. 133, “Accounting for Derivative Instruments and Hedging Activities,” we recognize all derivatives on the balance sheet at fair value. Derivatives that are not hedges must be adjusted to fair value through income. If a derivative is a hedge, depending on the nature of the hedge, changes in the fair value of the derivative will either be offset against the change in fair value of the hedged asset, liability, or firm commitment through earnings, or recognized in other comprehensive income until the hedged item is recognized in earnings. The ineffective portion of a derivative’s change in fair value will be immediately recognized in earnings. SFAS No. 133 may increase or decrease reported net income and stockholders’ equity prospectively, depending on future levels of interest rates and other variables affecting the fair values of derivative instruments and hedged items, but will have no effect on cash flows.

The following table summarizes the notional and fair value of our derivative financial instruments at March 31, 2007. The notional value is an indication of the extent of our involvement in these instruments at that time, but does not represent exposure to credit, interest rate or market risks (in thousands).

On March 31, 2007, the derivative instruments were reported as an asset at their fair value of approximately $4.2 million. This is included in Other Assets on the consolidated balance sheet at March 31, 2007. Offsetting adjustments are represented as deferred gains or losses in Accumulated Other Comprehensive Income of $11.6 million, including a gain of approximately $7.2 million from the settlement of a forward swap, which is being amortized over the ten-year term of the related mortgage obligation from December 2003. Currently, all of our derivative instruments are designated as effective hedging instruments.

We are hedging exposure to variability in future cash flows for forecasted transactions in addition to anticipated future interest payments on existing debt.

17. Environmental Matters

Our management believes that the properties are in compliance in all material respects with applicable Federal, state and local ordinances and regulations regarding environmental issues. Management is not aware of any environmental liability that it believes would have a materially adverse impact on our financial position, results of operations or cash flows. Management is unaware of any instances in which it would incur significant environmental cost if any of our properties were sold.

18. Segment Information

We are a REIT engaged in owning, managing, leasing, acquiring and repositioning commercial office and retail properties in Manhattan, Westchester County, Connecticut, Long Island City and New Jersey and have two reportable segments, real estate and structured finance investments. Our investment in Gramercy and its related earnings are included in the structured finance segment. We evaluate real estate performance and allocate resources based on earnings contribution to income from continuing operations.

Our real estate portfolio is primarily located in the geographical markets of Manhattan, Westchester, Connecticut, Long Island City and New Jersey. The primary sources of revenue are generated from tenant rents and escalations and reimbursement revenue. Real estate property operating expenses consist primarily of security, maintenance, utility costs, real estate taxes and ground rent expense (at certain applicable properties). See Note 5 for additional details on our structured finance investments.

Selected results of operations for the three months ended March 31, 2007 and 2006, and selected asset information as of March 31, 2007 and December 31, 2006, regarding our operating segments are as follows (in thousands):

December 31, 2006	4,068,571		563,656		4,632,227

Income from continuing operations represents total revenues less total expenses for the real estate segment and total investment income less allocated interest expense for the structured finance segment. Interest costs for the structured finance segment are imputed assuming 100% leverage at our unsecured revolving credit facility borrowing cost. We do not allocate marketing, general and administrative expenses (approximately $34.2 million and $13.0 million for the three months ended March 31, 2007 and 2006, respectively) to the structured finance segment, since we base performance on the individual segments prior to allocating marketing, general and administrative expenses. All other expenses, except interest, relate entirely to the real estate assets. There were no transactions between the above two segments.

20. Subsequent Events

In April 2007, we announced that we have acquired a 32.26% interest in the office condominium located at 1745 Broadway in Midtown Manhattan. The investment was made through a joint venture with SITQ and The Witkoff Group. The interest was acquired for approximately $66.5 million, valuing the office space at approximately $520.0 million. The property encompasses approximately 674,000 square feet.

In April 2007, we announced that we entered into an agreement to sell our office condominium interest in floors six through eighteen at 110 East 42nd Street for $111.5 million. The property encompasses approximately 181,000 square feet. This transaction, which is subject to customary closing conditions, is expected to close during the second quarter of 2007. The sale price does not include approximately 112,000 square feet of developable air rights, which we are retaining along with the ability to transfer these rights off-site.

In April 2007, we announced that we had entered into an agreement to sell our property located at 292 Madison Avenue for $140.0 million. The property encompasses approximately 187,000 square feet. This transaction, which is subject to customary closing conditions, is expected to close during the second quarter of 2007.

In April 2007, we announced that we had entered into an agreement to acquire the fee interest in 333 West 34th Street for $183.0 million from Citigroup Global Markets, Inc. The property encompasses approximately 345,000 square feet. At closing, Citigroup will enter into a full building triple net lease through 2009. This transaction, which is subject to customary closing conditions, is expected to close during the second quarter of 2007.

In April 2007, we announced that we had acquired 1 Jericho Plaza and 2 Jericho Plaza in Jericho, New York in a partnership with Onyx Equities and an affiliate of Credit Suisse Securities (USA) LLC, for $210.0 million. The property encompasses approximately 640,000 square feet. This transaction, which is subject to customary closing conditions, is expected to close during the second quarter of 2007.

In April 2007, we, along with Gramercy, together as tenants-in-common, acquired the fee interest in 2 Herald Square, a 354,400 square foot office and retail property located at 1328 Broadway in New York City. The fee interest, which is subject to a long-term operating lease, was purchased for $225.0 million. We own 55% of the fee and Gramercy owns the remaining 45%. The tenancy-in-common financed its acquisition with a $191.25 million, 10-year fixed rate loan provided by an affiliate of Goldman, Sachs & Co.

In April 2007, we entered into new employment agreements with each of Marc Holliday, Andrew Mathias, Gregory F. Hughes and Andrew Levine as well as with five other individuals. We recorded a one-time charge in the first quarter of approximately $13.0 million primarily in connection with these agreements.

ITEM 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Overview

SL Green Realty Corp., or the Company, a Maryland corporation, and SL Green Operating Partnership, L.P., or the Operating Partnership, a Delaware limited partnership, were formed in June 1997 for the purpose of combining the commercial real estate business of S.L. Green Properties, Inc. and its affiliated partnerships and entities. We are a self-managed real estate investment trust, or REIT, with in-house capabilities in property management, acquisitions, financing, development, construction and leasing. Unless the context requires otherwise, all references to “we,” “our” and “us” means the Company and all entities owned or controlled by the Company, including the Operating Partnership.

On January 25, 2007, we completed the acquisition, or the Reckson Merger, of all of the outstanding shares of common stock of Reckson Associates Realty Corp., or Reckson, pursuant to the terms of the Agreement and Plan of Merger, dated as of August 3, 2006, as amended, the Merger Agreement, among SL Green, Wyoming Acquisition Corp., or Wyoming, Wyoming Acquisition GP LLC, Wyoming Acquisition Partnership LP, Reckson and Reckson Operating Partnership, L.P. or ROP. Pursuant to the terms of the Merger Agreement, each of the issued and outstanding shares of common stock of Reckson were converted into the right to receive (i) $31.68 in cash, (ii) 0.10387 of a share of the common stock, par value $0.01 per share, of SL Green and (iii) a prorated dividend in an amount equal to approximately $0.0977 in cash. We also assumed an aggregate of approximately $226.3 million of Reckson mortgage debt, approximately $287.5 million of Reckson convertible public debt and approximately $967.8 million of Reckson public unsecured notes.

The following discussion related to our consolidated financial statements should be read in conjunction with the financial statements appearing in this report and in Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2006.

Location	Ownership	Number of Properties	Square Feet	Weighted Average Occupancy (1)
Manhattan	Consolidated properties	26	14,145,000	98.2	%
	Unconsolidated properties	8	7,966,900	95.9	%

Suburban	Consolidated properties	28	4,660,900	90.5	%
	Unconsolidated properties	1	1,402,000	100.0	%
		63	28,174,800

(1) The weighted average occupancy represents the total leased square feet divided by total available square feet.

We also own 505,000 square feet of retail (nine) and development (one) properties. In addition, we manage three office properties owned by third parties and affiliated companies encompassing approximately 1.0 million rentable square feet.

Critical Accounting Policies

Refer to our 2006 Annual Report on Form 10-K for a discussion of our critical accounting policies, which include rental property, investment in unconsolidated joint ventures, revenue recognition, allowance for doubtful accounts, reserve for possible credit losses and derivative instruments. There have been no material changes to these policies in 2007.

Results of Operations

Comparison of the three months ended March 31, 2007 to the three months ended March 31, 2006

The following comparison for the three months ended March 31, 2007, or 2007, to the three months ended March 31, 2006, or 2006, makes reference to the following: (i) the effect of the “Same-Store Properties,” which represents all properties owned by us at January 1, 2006 and at March 31, 2007 and total 19 of our 54 consolidated properties, representing approximately 40.0% of our share of annualized rental revenue, (ii) the effect of the “Acquisitions,” which represents all properties or interests in properties acquired in 2006, namely, 25-27 and 29 West 34PthP Street (January), 521 Fifth Avenue (March), 609 Fifth Avenue (June) and 717 Fifth Avenue (September), and in 2007, namely, 300 Main Street, 399 Knollwood and the Reckson assets (all January 2007) and (iii) “Other,” which represents corporate level items not allocable to specific properties, the Service Corporation and eEmerge. Assets classified as held for sale, are excluded from the following discussion.

Rental Revenues (in millions)	2007		2006		$ Change		% Change
Rental revenue	$	155.6	$	79.1	$	76.5	96.7	%
Escalation and reimbursement revenue	28.6		13.9		14.3		102.9
Total	$	184.2	$	93.0	$	91.2	98.1	%

Same-Store Properties	$	96.8	$	88.7	$	8.1	9.1	%
Acquisitions	85.2		2.6		82.6		3,176.9
Other	2.2		1.7		0.5		29.4
Total	$	184.2	$	93.0	$	91.2	98.1	%

Occupancy in the Same-Store Properties increased slightly from 96.0% at March 31, 2006 to 98.7% at March 31, 2007. The increase in the Acquisitions is primarily due to owning these properties for a period during the quarter in 2007 compared to a partial period or not being included in 2006.

At March 31, 2007, we estimated that the current market rents on our consolidated Manhattan properties and consolidated Suburban properties were approximately 33.1% and 16.4% higher, respectively, than then existing in-place fully escalated rents. We believe that the trend of increasing rental rates will continue during 2007. Approximately 4.2% of the space leased at our consolidated properties expires during the remainder of 2007. We believe that occupancy rates will increase slightly at the Same-Store Properties in 2007.

The increase in escalation and reimbursement revenue was due to the recoveries at the Same-Store Properties ($2.6 million) and the Acquisitions ($11.8 million). The increase in recoveries at the Same-Store Properties was primarily due to electric reimbursements ($0.8 million), operating expense escalations ($1.6 million) and real estate tax escalations ($0.2 million).

Investment and Other Income (in millions)	2007		2006		$ Change			% Change
Equity in net income of unconsolidated joint ventures	$	9.4	$	10.0	$	(0.6	)	(6.0	)%
Investment and preferred equity income	21.7		13.5		8.2			60.7
Other income	89.9		9.9		80.0			808.1
Total	$	121.0	$	33.4	$	87.6		262.3	%

The decrease in equity in net income of unconsolidated joint ventures was primarily due to lower net income contributions from 1515 Broadway ($0.8 million), 521 Fifth Avenue which is under redevelopment ($0.7 million) and the Mack-Green joint venture ($1.3 million). This was partially offset by increased net income contributions from our investments in Gramercy ($1.6 million) and One Park Avenue ($0.6 million). Occupancy at our joint venture properties decreased from 96.7% in 2006 to 95.9% in 2007 primarily due to increased vacancy at 1221 Avenue of the Americas and 521 Fifth Avenue. At March 31, 2007, we estimated that current market rents at our Manhattan and Suburban joint venture properties were approximately 38.3% and 11.0% higher, respectively, than then existing in-place fully escalated rents. Approximately 4.0% of the space leased at our joint venture properties expires during the remainder of 2007.

The increase in investment and preferred equity income was primarily due to higher outstanding balances during the current quarter. The weighted average investment balance outstanding and weighted average yield were $718.7 million and 9.98%, respectively, for 2007 compared to $453.1 million and 10.3%, respectively, for 2006.

The increase in other income was primarily due to an incentive distribution earned in 2007 upon the sale of One Park Avenue (approximately $77.2 million) as well by fee income earned by GKK Manager, an affiliate of ours and the external manager of Gramercy, (approximately $2.6 million).

Property Operating Expenses (in millions)	2007		2006		$ Change		% Change
Operating expenses	$	49.6	$	27.8	$	21.8	78.4	%
Real estate taxes	31.2		17.7		13.5		76.3
Ground rent	7.3		4.9		2.4		49.0
Total	$	88.1	$	50.4	$	37.7	74.8	%

Same-Store Properties	$	49.2	$	46.0	$	3.2	7.0	%
Acquisitions	35.0		1.0		34.0		3,400.0
Other	3.9		3.4		0.5		14.7
Total	$	88.1	$	50.4	$	37.7	74.8	%

Same-Store Properties operating expenses, excluding real estate taxes ($0.3 million), increased approximately $2.9 million. There were increases in repairs, maintenance and payroll expenses ($0.7 million), utilities ($2.1 million) and other miscellaneous expenses ($0.4 million), respectively. This was partially offset by a decrease in insurance costs ($0.3 million).

The increase in real estate taxes was primarily attributable to the Same-Store Properties ($0.3 million) due to higher assessed property values and the Acquisitions ($13.2 million).

Other Expenses (in millions)	2007		2006		$ Change		% Change
Interest expense	$	60.9	$	18.2	$	42.7	234.6	%
Depreciation and amortization expense	38.0		15.6		22.4		143.6
Marketing, general and administrative expense	34.2		13.0		21.2		163.1
Total	$	133.1	$	46.8	$	86.3	184.4	%

The increase in interest expense was primarily attributable to borrowings associated with new investment activity, primarily the Reckson Merger, and the funding of ongoing capital projects and working capital requirements. The weighted average interest rate decreased from 5.68% for the quarter ended March 31, 2006 to 5.64% for the quarter ended March 31, 2007. As a result of the new investment activity, the weighted average debt balance increased from $1.6 billion as of March 31, 2006 to $5.0 billion as of March 31, 2007.

Marketing, general and administrative expenses represented 11.6% of total revenues in 2007 compared to 11.2% in 2006. The increase is primarily due to a one-time charge of $13.0 million associated with nine new employment agreements as well as additional hiring due to the Reckson Merger.

Liquidity and Capital Resources

We currently expect that our principal sources of working capital and funds for acquisition and redevelopment of properties, tenant improvements and leasing costs and for structured finance investments will include:

(1) Cash flow from operations;

(2) Borrowings under our 2005 unsecured revolving credit facility;

(3) Other forms of secured or unsecured financing;

(4) Proceeds from common or preferred equity or debt offerings by us or the Operating Partnership (including issuances of limited partnership units in the Operating Partnership and trust preferred securities); and

(5) Net proceeds from divestitures of properties and redemptions and participations of structured finance investments.

Cash flow from operations is primarily dependent upon the occupancy level of our portfolio, the net effective rental rates achieved on our leases, the collectibility of rent and operating escalations and recoveries from our tenants and the level of operating and other costs. Additionally, we believe that our joint venture investment programs will also continue to serve as a source of capital for acquisitions.

We believe that our sources of working capital, specifically our cash flow from operations and borrowings available under our 2005 unsecured revolving credit facility, and our ability to access private and public debt and equity capital, are adequate for us to meet our short-term and long-term liquidity requirements for the foreseeable future.

Cash Flows

The following summary discussion of our cash flows is based on our condensed consolidated statements of cash flows in “Item 1. Financial Statements” and is not meant to be an all-inclusive discussion of the changes in our cash flows for the periods presented below.

Cash and cash equivalents were $499.7 million and $117.2 million at March 31, 2007 and December 31, 2006, respectively, representing an increase of $382.5 million. The increase was a result of the following increases and decreases in cash flows (in thousands):

	Three months ended March 31,
	2007			2006			Increase (Decrease)
Net cash provided by operating activities	$	135,247		$	33,399		$	101,848
Net cash used in investing activities	$	(2,916,868	)	$	(306,503	)	$	2,610,365
Net cash provided by financing activities	$	3,164,171		$	269,535		$	2,894,636

Our principal source of operating cash flow is related to the leasing and operating of the properties in our portfolio. Our properties provide a relatively consistent stream of cash flow that provides us with resources to pay operating expenses, debt service and fund quarterly dividend and distribution payment requirements. At March 31, 2007 our portfolio was 96.3% occupied. In addition, rental rates continue to increase and tenant concession packages decrease in the Manhattan and Suburban marketplace. Our structured finance and joint venture investments also provide a steady stream of operating cash flow to us.

Cash is used in investing activities to fund acquisitions, redevelopment projects and recurring and nonrecurring capital expenditures. We selectively invest in new projects that enable us to take advantage of our development, leasing, financing and property management skills and invest in existing buildings that meet our investment criteria. In the first quarter of 2007, we acquired Reckson for approximately $4.0 billion which included the assumption of approximately $1.5 billion of consolidated debt. During the three months ended March 31, 2007, we used cash primarily for the following investing activities (in thousands):

Acquisitions of real estate	$	(2,503,400	)
Capital expenditures and capitalized interest	(10,714		)
Escrow cash-capital improvements/acquisition deposits	140,848
Joint venture investments	(60,157		)
Distributions from joint ventures	9,164
Proceeds from sales of real estate	49,574
Structured finance and other investments	(235,682		)

We generally fund our investment activity through property-level financing, our 2005 unsecured revolving credit facility, term loans, unsecured notes, construction loans and from time to time we issue common stock. During the three months ended March 31, 2007, the following financing activities provided the funds to complete the investing activity noted above (in thousands):

Proceeds from our debt obligations	$	2,017,337
Repayments under our debt obligations	(605,927		)
Net proceeds from issuance of common stock	1,010,078
Other financing activities	484,305
Dividends and distributions paid	(11,156		)

Capitalization

As of March 31, 2007, we had 59,181,651 shares of common stock, 2,618,700 units of limited partnership interest in our operating partnership, 6,300,000 shares of our 7.625% Series C cumulative redeemable preferred stock, or Series C preferred stock, and 4,000,000 shares of our 7.875% Series D cumulative redeemable preferred stock, or Series D preferred stock, outstanding.

In March 2007, our Board of Directors approved a stock purchase plan under which we can buy up to $300.0 million of our common stock. This plan will expire on December 31, 2008. In April 2007, we purchased approximately 16,000 shares of our common stock at an average price of $132.48 per share.

Rights Plan

We adopted a shareholder rights plan which provides, among other things, that when specified events occur, our shareholders will be entitled to purchase from us a new created series of junior preferred shares, subject to our ownership limit described below. The preferred share purchase rights are triggered by the earlier to occur of (1) ten days after the date of a purchase announcement that a person or group acting in concert has acquired, or obtained the right to acquire, beneficial ownership of 17% or more of our outstanding shares of common stock or (2) ten business days after the commencement of or announcement of an intention to make a tender offer or exchange offer, the consummation of which would result in the acquiring person becoming the beneficial owner of 17% or more of our outstanding common stock. The preferred share purchase rights would cause substantial dilution to a person or group that attempts to acquire us on terms not approved by our board of directors.

Dividend Reinvestment and Stock Purchase Plan

We filed a registration statement with the SEC for our dividend reinvestment and stock purchase plan, or DRIP which was declared effective on September 10, 2001. The DRIP commenced on September 24, 2001. We registered 3,000,000 shares of common stock under the DRIP.

2003 Long-Term Outperformance Compensation Program

2005 Long-Term Outperformance Compensation Program

vesting, with one-third of the LTIP Units earned vesting on November 30, 2008 and each of the first two anniversaries thereafter based on continued employment. On June 14, 2006, the Compensation Committee determined that under the terms of the 2005 Outperformance Plan, as of June 8, 2006, the performance period had accelerated and the maximum performance pool of $49,250,000, taking into account forfeitures, was established. Individual awards under the 2005 Outperformance Plan are in the form of partnership units, or LTIP Units, in SL Green Operating Partnership, L.P., that, subject to certain conditions, are convertible into shares of the Company’s common stock or cash, at the Company’s election. The total number of LTIP Units earned by all participants as a result of the establishment of the performance pool was 490,475 and are subject to time-based vesting.

2006 Long-Term Outperformance Compensation Program

On August 14, 2006, the compensation committee of our board of directors approved a long-term incentive compensation program, the 2006 Outperformance Plan. Participants in the 2006 Outperformance Plan will share in a “performance pool” if our total return to stockholders for the period from August 1, 2006 through July 31, 2009 exceeds a cumulative total return to stockholders of 30% during the measurement period over a base share price of $106.39 per share. The size of the pool will be 10% of the outperformance amount in excess of the 30% benchmark, subject to a maximum award of $60 million. The maximum award will be reduced by the amount of any unallocated or forfeited awards. In the event the potential performance pool reaches the maximum award before July 31, 2009 and remains at that level or higher for 30 consecutive days, the performance period will end early and the pool will be formed on the last day of such 30 day period. Each participant’s award under the 2006 Outperformance Plan will be designated as a specified percentage of the aggregate performance pool. Assuming the 30% benchmark is achieved, the pool will be allocated among the participants in accordance with the percentage specified in each participant’s participation agreement. Individual awards will be made in the form of partnership units, or LTIP Units, that, subject to vesting and the satisfaction of other conditions, are exchangeable for a per unit value equal to the then trading price of one share of our common stock. This value is payable in cash or, at our election, in shares of common stock. LTIP Units will be granted prior to the determination of the performance pool; however, they will only vest upon satisfaction of performance and time vesting thresholds under the 2006 Outperformance Plan, and will not be entitled to distributions until after the performance pool is established. Distributions on LTIP Units will equal the dividends paid on our common stock on a per unit basis. The 2006 Outperformance Plan provides that if the pool is established, each participant will also be entitled to the distributions that would have been paid had the number of earned LTIP Units been issued at the beginning of the performance period. Those distributions will be paid in the form of additional LTIP Units. Thereafter, distributions will be paid currently with respect to all earned LTIP Units that are a part of the performance pool, whether vested or unvested. Although the amount of earned awards under the 2006 Outperformance Plan (i.e. the number of LTIP Units earned) will be determined when the performance pool is established, not all of the awards will vest at that time. Instead, one-third of the awards will vest on July 31, 2009 and each of the first two anniversaries thereafter based on continued employment.

Deferred Stock Compensation Plan for Directors

for an equivalent amount of phantom stock units based on the dividend rate for each quarter.

During the three months ended March 31, 2007, approximately 3,567 phantom stock units were earned. As of March 31, 2007, there were approximately 14,127 phantom stock units outstanding.

2005 Stock Option and Incentive Plan

Subject to adjustments upon certain corporate transactions or events, up to a maximum of 4,375,000 shares, or the Fungible Pool Limit, may be granted as options, restricted stock, phantom shares, dividend equivalent rights and other equity-based awards under the 2005 Stock Option and Incentive Plan, or the 2005 Plan. At March 31, 2007, approximately 2.0 million shares of our common stock, calculated on a weighted basis, were available for issuance under the 2005 Plan, or 2.5 million shares if all shares available under the 2005 Plan were issued as five-year options.

At March 31, 2007, borrowings under our mortgage loans, 2005 unsecured revolving credit facility, term loan, unsecured bridge loan, unsecured notes and trust preferred securities (including our share of joint venture debt of approximately $1.3 billion) represented 41.9% of our combined market capitalization of approximately $15.0 billion (based on a common stock price of $137.18 per share, the closing price of our common stock on the New York Stock Exchange on March 31, 2007). Market capitalization includes our consolidated debt, common and preferred stock and the conversion of all units of limited partnership interest in our Operating Partnership, and our share of joint venture debt.

Indebtedness

The table below summarizes our consolidated mortgage debt, 2005 unsecured revolving credit facility, term loan, unsecured bridge loan, unsecured notes and trust preferred securities outstanding at March 31, 2007 and December 31, 2006, respectively (dollars in thousands).

The variable rate debt shown above bears interest at an interest rate based on 30-day LIBOR (5.32% and 4.83% at March 31, 2007 and 2006, respectively). Our consolidated debt at March 31, 2007 had a weighted average term to maturity of approximately 8.8 years.

Certain of our structured finance investments, totaling approximately $103.1 million, are variable rate investments which mitigate our exposure to interest rate changes on our unhedged variable rate debt at March 31, 2007.

Mortgage Financing

As of March 31, 2007, our total mortgage debt (excluding our share of joint venture debt of approximately $1.3 billion) consisted of approximately $1.8 billion of fixed rate debt, including hedged variable rate debt, with an effective weighted average interest rate of approximately 6.01% and $0.4 billion of variable rate debt with an effective weighted average interest rate of approximately 7.10%.

Corporate Indebtedness

2005 Unsecured Revolving Credit Facility

We have a $800.0 million unsecured revolving credit facility. We increased the capacity under the 2005 unsecured revolving credit facility from $500.0 million. The 2005 unsecured revolving credit facility bears interest at a spread ranging from 85 basis points to 125 basis points over the 30-day LIBOR, based on our leverage ratio, currently 110 basis points. This facility matures in September 2008 and has a one-year extension option. The 2005 unsecured revolving credit facility also requires a 12.5 to 25 basis point fee on the unused balance payable annually in arrears. The 2005 unsecured revolving credit facility had no balance outstanding at March 31, 2007. Availability under the 2005 unsecured revolving credit facility was further reduced by the issuance of approximately $15.3 million in letters of credit. The 2005 unsecured revolving credit facility includes certain restrictions and covenants (see restrictive covenants below).

Term Loans

We had a $325.0 million unsecured term loan, which was scheduled to mature in August 2009. The effective all-in weighted average interest rate on the unsecured term loan was 5.63% for three months ended March 31, 2007. The unsecured term loan was repaid and terminated in March 2007.

We also have a $200.0 million five-year non-recourse term loan, secured by a pledge of our ownership interest in 1221 Avenue of the

Americas. The loan matures in May 2010. This term loan has a floating rate of 125 basis points over the current 30-day LIBOR rate. During April 2004, we entered into a swap agreement to fix the LIBOR at a blended all-in interest rate of 5.10% through December 2008. This loan carried an effective all-in weighted average interest rate of 5.96% for the three months ended March 31, 2007.

In January 2007, we closed on a $500.0 million unsecured bridge loan, which matures in January 2010. This bridge loan bears interest at a spread ranging from 85 basis points to 125 basis points over LIBOR, based on our leverage ratio. As of March 31, 2007, we had $500.0 million outstanding under the unsecured bridge loan at the rate of 110 basis points over LIBOR. This bridge loan is prepayable at any time without penalty. The effective all-in interest rate on the unsecured bridge loan was 6.42% for three months ended March 31, 2007. The unsecured bridge loan includes certain restrictions and covenants (see restrictive covenants below).

Unsecured Notes

In March 2007, we issued $750.0 million of 3.00% exchangeable senior notes which are due in 2027. The notes were offered in accordance with Rule 144A under the Securities Act of 1933, as amended. The notes will pay interest semiannually at a rate of 3.00% per annum and mature on March 30, 2027. Interest on these notes is payable semi-annually on March 30 and September 30. The notes will have an initial exchange rate representing an exchange price that is at a 25.0% premium to the last reported sale price of our common stock on March 20, 2007, or $173.30. The initial exchange rate is subject to adjustment under certain circumstances. The notes will be senior unsecured obligations of our operating partnership and will be exchangeable upon the occurrence of specified events, and during the period beginning on the twenty-second scheduled trading day prior to the maturity date and ending on the second business day prior to the maturity date, into cash or a combination of cash and shares of our common stock, if any, at our option. The notes will be redeemable, at our option, on and after April 15, 2012. We may be required to repurchase the notes on March 30, 2012, 2017 and 2022, and upon the occurrence of certain designated events. The net proceeds from the offering were approximately $736.0 million, after deducting estimated fees and expenses. The proceeds of the offering were used to repay certain of our existing indebtedness, make investments in additional properties, and make open market purchases of our common stock and for general corporate purposes.

As of March 31, 2007, we had outstanding approximately $2.0 billion (net of unamortized issuance discounts) of senior unsecured notes.

The following table sets forth our senior unsecured notes and other related disclosures by scheduled maturity date (in thousands):

Junior Subordinate Deferrable Interest Debentures

In June 2005, we issued $100.0 million of Trust Preferred Securities, which are reflected on the balance sheet at March 31, 2007 as Junior Subordinate Deferrable Interest Debentures. The proceeds were used to repay our 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.

Restrictive Covenants

The terms of our 2005 unsecured revolving credit facility and unsecured bridge loan and unsecured bonds include certain restrictions and covenants which limit, among other things, the payment of dividends (as discussed below), the incurrence of additional indebtedness, the incurrence of liens and the disposition of assets, and which require compliance with financial ratios relating to the minimum amount of tangible net worth, the minimum amount of debt service coverage, the minimum amount of fixed charge coverage, the maximum amount of unsecured indebtedness, the minimum amount of unencumbered property debt service coverage and certain investment limitations. The dividend restriction referred to above provides that, except to enable us to continue to qualify as a REIT for Federal income tax purposes, we will not during any four consecutive fiscal quarters make distributions with respect to common stock or other equity interests in an aggregate amount in excess of 90% of funds from operations for such period, subject to certain other adjustments. As of March 31, 2007 and December 31, 2006, we were in compliance with all such covenants.

Market Rate Risk

We are exposed to changes in interest rates primarily from our floating rate borrowing arrangements. We use interest rate derivative instruments to manage exposure to interest rate changes. A hypothetical 100 basis point increase in interest rates along the entire interest rate curve for 2007 would increase our annual interest cost by approximately $8.9 million and would increase our share of joint venture annual interest cost by approximately $6.9 million, respectively.

We recognize all derivatives on the balance sheet at fair value. Derivatives that are not hedges must be adjusted to fair value through income. If a derivative is a hedge, depending on the nature of the hedge, changes in the fair value of the derivative will either be offset against the change in fair value of the hedged asset, liability, or firm commitment through earnings, or recognized in other comprehensive income until the hedged item is recognized in earnings. The ineffective portion of a derivative’s change in fair value is immediately recognized in earnings.

Approximately $4.3 billion of our long-term debt bears interest at fixed rates, and therefore the fair value of these instruments is affected by changes in the market interest rates. The interest rate on our variable rate debt and joint venture debt as of March 31, 2007 ranged from LIBOR plus 75 basis points to LIBOR plus 275 basis points.

Contractual Obligations

Combined aggregate principal maturities of mortgages and notes payable, 2005 unsecured revolving credit facility, term loan, unsecured bridge loan, unsecured notes and bonds, trust preferred securities, our share of joint venture debt, excluding extension options, estimated interest expense, and our obligations under our capital lease, air rights and ground leases, as of March 31, 2007 are as follows (in thousands):

Off-Balance Sheet Arrangements

We have a number of off-balance sheet investments, including joint ventures and structured finance investments. These investments all have varying ownership structures. Substantially all of our joint venture arrangements are accounted for under the equity method of accounting as we have the ability to exercise significant influence, but not control over the operating and financial decisions of these joint venture arrangements. Our off-balance sheet arrangements are discussed in Note 5, “Structured Finance Investments” and Note 6, “Investments in Unconsolidated Joint Ventures” in the accompanying financial statements.

Capital Expenditures

We estimate that for the nine months ending December 31, 2007, we will incur approximately $161.7 million of capital expenditures (including tenant improvements and leasing commissions) on existing wholly-owned properties and our share of capital expenditures at our joint venture properties will be approximately $35.9 million. We expect to fund these capital expenditures with operating cash flow, borrowings under our credit facilities, additional property level mortgage financings, and cash on hand. Future property acquisitions may require substantial capital investments for refurbishment and leasing costs. We expect that these financing requirements will be met in a similar fashion. We believe that we will have sufficient resources to satisfy our capital needs during the next 12-month period. Thereafter, we expect that our capital needs will be met through a combination of net cash provided by operations, borrowings, potential asset sales or additional equity or debt issuances.

Dividends

We expect to pay dividends to our stockholders based on the distributions we receive from our Operating Partnership primarily from property revenues net of operating expenses or, if necessary, from working capital or borrowings.

To maintain our qualification as a REIT, we must pay annual dividends to our stockholders of at least 90% of our REIT taxable income, determined before taking into consideration the dividends paid deduction and net capital gains. We intend to continue to pay regular quarterly dividends to our stockholders. Based on our current annual dividend rate of $2.80 per share, we would pay approximately $166.4 million in dividends. Before we pay any dividend, whether for Federal income tax purposes or otherwise, which would only be paid out of available cash to the extent permitted under our unsecured and secured credit facilities, and our term loans, we must first meet both our operating requirements and scheduled debt service on our mortgages and loans payable.

Leases

Nancy Peck and Company leases 2,013 square feet of space at 420 Lexington Avenue pursuant to a lease that expired on June 30, 2005 and provided for annual rental payments of approximately $66,000. This space is now leased on a month-to-month basis. Nancy Peck and Company is owned by Nancy Peck, the wife of Stephen L. Green. The rent due under the lease is offset against a consulting fee, of $11,025 per month, are affiliate pays to her under a consulting agreement which is cancelable upon 30-days notice. The consulting agreement was cancelled in July 2006.

Management Fees

S.L. Green Management Corp. receives property management fees from certain entities in which Stephen L. Green owns an interest. The aggregate amount of fees paid to S.L. Green Management Corp. from such entities was approximately $66,000 and $43,000 for the three months ended March 31, 2007 and 2006, respectively.

Management Indebtedness

In January 2001, Mr. Marc Holliday, then our president, received a non-recourse loan from us in the principal amount of $1,000,000 pursuant to his amended and restated employment and non-competition agreement he executed at that time. This loan bears interest at the applicable federal rate per annum and is secured by a pledge of certain of Mr. Holliday’s shares of our common stock. The principal of and interest on this loan is forgivable upon our attainment of specified financial performance goals prior to December 31, 2006, provided that Mr. Holliday remains employed by us until January 2007. As a result of the performance goals being met, this loan was forgiven in January 2007. In April 2000, Mr. Holliday received a loan from us in the principal amount of $300,000, with a maturity date of July 2003. This loan bore interest at a rate of 6.60% per annum and was secured by a pledge of certain of Mr. Holliday’s shares of our common stock. In May 2002, Mr. Holliday entered into a loan modification agreement with us in order to modify the repayment terms of the $300,000 loan. Pursuant to the agreement, one-third of the $300,000 was forgiven on each of January 1, 2004, January 1, 2005 and January 1, 2006, provided that Mr. Holliday remained employed by us through each of such date. This $300,000 loan was completely forgiven on January 1, 2006.

Other

Insurance

We maintain “all-risk” property and rental value coverage (including coverage regarding the perils of flood, earthquake and terrorism) and liability insurance with limits in excess of $200.0 million per location. The property policies expire on December 31, 2007 and the liability policies expire on October 31, 2007. SL Green now maintains two property insurance portfolios. The first portfolio maintains a blanket limit of $600.0 million per occurrence for the majority of the New York City properties in our portfolio with a sub-limit of $450.0 million for acts of terrorism. The second portfolio maintains a $600.0 million per occurrence, including terrorism, for the majority of the Suburban properties. The New York City portfolio incorporates our captive, Belmont Insurance Company, which we formed in an effort to stabilize, to some extent, the fluctuations of insurance market conditions. Belmont is licensed to write up to $100.0 million of coverage for us, but at this time is providing $50.0 million of terrorism coverage in excess of $100.0 million and is insuring a large deductible on the liability insurance with a $250,000 deductible per occurrence and a $2.4 million annual aggregate loss limit. We have secured an excess insurer to protect against catastrophic liability losses (above $250,000 / occurrence and a stop loss for aggregate claims that exceed $2.4 million. We have retained a third party administrator to manage all claims within the deductible and we anticipate that direct management of liability claims will improve loss experience and ultimately lower the cost of liability insurance in future years. We have a 45% interest in the property at 1221 Avenue of the Americas, where we participate with The Rockefeller Group Inc., which carries a blanket policy providing $1.0 billion of “all-risk” property insurance, including terrorism coverage, and a 49.9% interest in the property at 100 Park Avenue, where we participate with Prudential, which carries a blanket policy of $500.0 million of “all-risk” property insurance, including terrorism coverage. We, together with Gramercy, own One Madison Avenue, which is under a triple net lease with insurance provided by the tenant, Credit Suisse Securities (USA) LLC. Although we consider our insurance coverage to be appropriate, in the event of a major catastrophe, such as an act of terrorism, we may not have sufficient coverage to replace certain properties.

In October 2006, we formed a wholly-owned taxable REIT subsidiary, Belmont, to act as a captive insurance company and be one of the elements of our overall insurance program. Belmont acts as a direct property insurer with respect to a portion of our terrorism coverage for the NYC portfolio and provides primary liability insurance to cover the deductible program. As long as we own Belmont, we are responsible for its liquidity and capital resources, and the accounts of Belmont are part of our consolidated financial statements. If we experience a loss and Belmont is required to pay under its insurance policy, we would ultimately record the loss to the extent of Belmont’s required payment. Therefore, insurance coverage provided by Belmont should not be considered as the equivalent of third-party insurance, but rather as a modified form of self-insurance.

The Terrorism Risk Insurance Act, or TRIA, which was enacted in November 2002, was renewed on January 1, 2006. Congress extended TRIA, now called TRIEA (Terrorism Risk Insurance Extension Act) until December 31, 2007. The law extends the federal Terrorism Insurance Program that requires insurance companies to offer terrorism coverage and provides for compensation for insured losses resulting from acts of terrorism. Our debt instruments, consisting of mortgage loans secured by our properties (which are generally non-recourse to us), mezzanine loans, ground leases and our 2005 unsecured revolving credit facility and secured and unsecured term loans, contain customary covenants requiring us to maintain insurance. There can be no assurance that the lenders or ground lessors under these instruments will not take the position that a total or partial exclusion from “all-risk” insurance coverage for losses due to terrorist acts is a breach of these debt and ground lease instruments that allows the lenders or ground lessors to declare an event of default and accelerate repayment of debt or recapture of ground lease positions. In addition, if lenders insist on full coverage for these risks and prevail in asserting that we are required to maintain such coverage, it could result in substantially higher insurance premiums.

Funds from Operations

Funds from Operations, or FFO, is a widely recognized measure of REIT performance. We compute FFO in accordance with standards established by the National Association of Real Estate Investment Trusts, or NAREIT, which may not be comparable to FFO reported by other REITs that do not compute FFO in accordance with the NAREIT definition, or that interpret the NAREIT definition differently than we do. The revised White Paper on FFO approved by the Board of Governors of NAREIT in April 2002 defines FFO as net income (loss) (computed in accordance with Generally Accepted Accounting Principles, or GAAP), excluding gains (or losses) from debt restructuring and sales of properties, plus real estate related depreciation and amortization and after adjustments for unconsolidated partnerships and joint ventures. We present FFO because we consider it an important supplemental measure of our operating performance and believe that it is frequently used by securities analysts, investors and other interested parties in the evaluation of REITs, particularly those that own and operate commercial office properties.

We also use FFO as one of several criteria to determine performance-based bonuses for members of our senior management. FFO is intended to exclude GAAP historical cost depreciation and amortization of real estate and related assets, which assumes that the value of real estate assets diminishes ratably over time. Historically, however, real estate values have risen or fallen with market conditions. Because FFO excludes depreciation and amortization unique to real estate, gains and losses from property dispositions and extraordinary items, it provides a performance measure that, when compared year over year, reflects the impact to operations from

trends in occupancy rates, rental rates, operating costs, interest costs, providing perspective not immediately apparent from net income. FFO does not represent cash generated from operating activities in accordance with GAAP and should not be considered as an alternative to net income (determined in accordance with GAAP), as an indication of our financial performance or to cash flow from operating activities (determined in accordance with GAAP) as a measure of our liquidity, nor is it indicative of funds available to fund our cash needs, including our ability to make cash distributions.

FFO for the three months ended March 31, 2007 and 2006 are as follows (in thousands):

	Three months ended March 31,

Inflation

Substantially all of the office leases provide for separate real estate tax and operating expense escalations as well as operating expense recoveries based on increases in the Consumer Price Index or other measures such as porters’ wage. In addition, many of the leases provide for fixed base rent increases. We believe that inflationary increases may be at least partially offset by the contractual rent increases and expense escalations described above.

Forward-Looking Information

This report includes certain statements that may be deemed to be “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933, as amended, or the Act, and Section 21E of the Securities Exchange Act of 1934, as amended, or the Exchange Act. Such forward-looking statements relate to, without limitation, our future capital expenditures, dividends and acquisitions (including the amount and nature thereof) and other development trends of the real estate industry and the Manhattan, Westchester, Connecticut, Long Island City and New Jersey office market, business strategies, and the expansion and growth of our operations. These statements are based on certain assumptions and analyses made by us in light of our experience and our perception of historical trends, current conditions, expected future developments and other factors we believe are appropriate. We intend such forward-looking statements to be covered by the safe harbor provisions for forward-looking statements contained in Section 27A of the Act and Section 21E of the Exchange Act. Such statements are subject to a number of assumptions, risks and uncertainties which may cause our actual results, performance or achievements to be materially different from future results, performance or achievements expressed or implied by these forward-looking statements. Forward-looking statements are generally identifiable by the use of the words “may,” “will,” “should,” “expect,” “anticipate,” “estimate,” “believe,” “intend,” “project,” “continue,” or the negative of these words, or other similar words or terms. Readers are cautioned not to place undue reliance on these forward-looking statements. Among the factors about which we have made assumptions are:

· general economic or business (particularly real estate) conditions, either nationally or in New York City, Westchester, Connecticut, Long Island City and New Jersey being less favorable than expected;

· reduced demand for office space;

· risks of real estate acquisitions;

· risks of structured finance investments;

· availability and creditworthiness of prospective tenants;

· adverse changes in the real estate markets, including increasing vacancy, decreasing rental revenue and increasing insurance costs;

· availability of capital (debt and equity);

· unanticipated increases in financing and other costs, including a rise in interest rates;

· market interest rates could adversely affect the market price of our common stock, as well as our performance and cash flows;

· our ability to satisfy complex rules in order for us to qualify as a REIT, for federal income tax purposes, our Operating Partnership’s ability to satisfy the rules in order for it to qualify as a partnership for federal income tax purposes, the ability of certain of our subsidiaries to qualify as REITs and certain of our subsidiaries to qualify as taxable REIT subsidiaries for federal income tax purposes and our ability and the ability of our subsidiaries to operate effectively within the limitations imposed by these rules;

· accounting principles and policies and guidelines applicable to REITs;

· competition with other companies;

· the continuing threat of terrorist attacks on the national, regional and local economies including, in particular, the New York City area and our tenants;

· legislative or regulatory changes adversely affecting real estate investment trusts and the real estate business; and

· environmental, regulatory and/or safety requirements.

We undertake no obligation to publicly update or revise any forward-looking statements, whether as a result of future events, new information or otherwise.

The risks included here are not exhaustive. Other sections of this report may include additional factors that could adversely affect the Company’s business and financial performance. Moreover, the Company operates in a very competitive and rapidly changing environment. New risk factors emerge from time to time and it is not possible for management to predict all such risk factors, nor can it assess the impact of all such risk factors on the Company’s business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. Given these risks and uncertainties, investors should not place undue reliance on forward-looking statements as a prediction of actual results.

ITEM 3. Quantitative and Qualitative Disclosure About Market Risk

For quantitative and qualitative disclosures about market risk, see item 7A, “Quantitative and Qualitative Disclosures About Market Risk,” of our Annual Report on Form 10-K for the year ended December 31, 2006. Our exposures to market risk have not changed materially since December 31, 2006.

ITEM 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure based closely on the definition of “disclosure controls and procedures” in Rule 13a-15(e) of the Exchange Act. Notwithstanding the foregoing, a control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that it will detect or uncover failures within the Company to disclose material information otherwise required to be set forth in our periodic reports. Also, we have investments in certain unconsolidated entities. As we do not control these entities, our disclosure controls and procedures with respect to such entities are necessarily substantially more limited than those we maintain with respect to our consolidated subsidiaries.

As of the end of the period covered by this report, we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and our Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of the end of the period covered by this report.

Changes in Internal Control over Financial Reporting

There have been no significant changes in our internal control over financial reporting during the quarter ended March 31, 2007, that has materially affected, or is reasonably likely to material affect, our internal control over financial reporting.

PART II OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

As of March 31, 2007, we were not involved in any material litigation nor, to management’s knowledge, is any material litigation threatened against us or our portfolio other than routine litigation arising in the ordinary course of business or litigation that is adequately covered by insurance.

On December 6, 2006, the company announced that it and Reckson Associates Realty Corp. had reached an agreement in principal to settle the previously disclosed class action lawsuits relating to the SL Green/Reckson merger. The settlement, which remains subject to documentation and judicial review and approval, provides (1) for certain contingent profit sharing participations for Reckson stockholders relating to specified assets, (2) for potential payments to Reckson stockholders of amounts relating to Reckson’s interest in contingent profit sharing participations in connection with the sale of certain Long Island industrial properties in a prior transaction, and (3) for the dismissal by the plaintiffs of all actions with prejudice and customary releases of all defendants and related parties.

ITEM 1A. RISK FACTORS

Declines in the demand for office space in New York City, and in particular, in midtown Manhattan, as well as Westchester, Connecticut, New Jersey and Long Island City, resulting from general economic conditions could adversely affect the value of our real estate portfolio and our results of operations and, consequently, our ability to service current debt and to pay dividends to stockholders.

Most of our commercial office properties are located in midtown Manhattan. As a result, our business is dependent on the condition of the New York City economy in general and the market for office space in midtown Manhattan, in particular. Weakness in the New York City economy could materially reduce the value of our real estate portfolio and our revenues, and thus adversely affect our ability to service current debt and to pay dividends to stockholders. We could also be impacted by weakness in our Suburban markets, including Westechester, Connecticut, New Jersey and Long Island City.

We may be unable to renew leases or relet space as leases expire.

When our tenants decide not to renew their leases upon their expiration, we may not be able to relet the space. Even if tenants do renew or we can relet the space, the terms of renewal or reletting, including the cost of required renovations, may be less favorable than current lease terms. Over the next five years, through the end of 2011, leases will expire on approximately 36.8% and 32.0% of the rentable square feet at our consolidated properties and unconsolidated joint venture properties, respectively. As of March 31, 2007, approximately 6.7 million and 2.9 million square feet are scheduled to expire by December 31, 2011 at our consolidated properties and unconsolidated joint venture properties, respectively, and these leases currently have annualized escalated rental income totaling approximately $264.7 million and $141.7 million, respectively. If we are unable to promptly renew the leases or relet this space at similar rates, our cash flow and ability to service debt and pay dividends to stockholders would be adversely affected.

The expiration of long term leases or operating sublease interests could adversely affect our results of operations.

Our interest in nine of our commercial office properties is through either long-term leasehold or operating sublease interests in the land and the improvements, rather than by a fee interest in the land. Unless we can purchase a fee interest in the underlying land or extend the terms of these leases before their expiration, we will lose our right to operate these properties and our interest in the improvements upon expiration of the leases, which would significantly adversely affect our results of operations. These properties are 673 First Avenue, 420 Lexington Avenue, 461 Fifth Avenue, 711 Third Avenue, 625 Madison Avenue, 521 Fifth Avenue, 919 Third Avenue, 1185 Avenue of the Americas, and 1055 Washington Avenue, CT. The average remaining term of these long-term leases, including our unilateral extension rights on each of the properties, is approximately 25 years. Pursuant to the operating sublease arrangements, we, as tenant under the operating sublease, perform the functions traditionally performed by landlords with respect to our subtenants. We are responsible for not only collecting rent from our subtenants, but also maintaining the property and paying expenses relating to the property. Our share of annualized escalated rents of these properties at March 31, 2007 totaled approximately $256.3 million, or 27.8%, of our share of total portfolio annualized revenue associated with these properties.

Reliance on major tenants and insolvency or bankruptcy of these and other tenants could adversely affect our results of operations.

Giving effect to leases in effect as of March 31, 2007 for consolidated properties and unconsolidated joint venture properties as of that date, our five largest tenants, based on square footage leased, accounted for approximately 20.0% of our share of portfolio annualized rent, and, other than three tenants, Citigroup, N.A., Viacom International Inc. and Credit Suisse Securities (USA) LLC who accounted for approximately 5.7%, 6.4% and 4.2% of our share of portfolio annualized rent, respectively, and no tenant accounted for more than 2.7% of that total. Our business would be adversely affected if any of these tenants or any other tenants became insolvent, declared bankruptcy or otherwise refused to pay rent in a timely fashion or at all.

We may suffer adverse consequences if our revenues decline since our operating costs do not necessarily decline in proportion to our revenue.

We earn a significant portion of our income from renting our properties. Our operating costs, however, do not necessarily fluctuate in relation to changes in our rental revenue. This means that our costs will not necessarily decline even if our revenues do. Our operating costs could also increase while our revenues do not. If our operating costs increase but our rental revenues do not, we may be forced to borrow to cover our costs, we may incur losses and we may not have cash available for distributions to our stockholders.

We face risks associated with property acquisitions.

We intend to acquire individual properties and portfolios of properties, including large portfolios that could significantly increase our size and alter our capital structure. Our acquisition activities and their success may be exposed to the following risks:

· we may be unable to acquire a desired property because of competition from other well capitalized real estate investors, including publicly traded REITs, institutional investment funds and private investors or at all;

· even if we enter into an acquisition agreement for a property, it is usually subject to customary conditions to closing, including due diligence investigations to our satisfaction;

· even if we are able to acquire a desired property, competition from other real estate investors may significantly increase the purchase price;

· we may be unable to finance acquisitions on favorable terms or at all;

· acquired properties may fail to perform as we expected;

· our estimates of the costs of repositioning or redeveloping acquired properties may be inaccurate;

· we may not be able to obtain adequate insurance coverage for new properties;

· acquired properties may be located in new markets where we may face risks associated with a lack of market knowledge or understanding of the local economy, lack of business relationships in the area and unfamiliarity with local governmental and permitting procedures; and

· we may be unable to quickly and efficiently integrate new acquisitions, particularly acquisitions of portfolios of properties, into our existing operations, and as a result our results of operations and financial condition could be adversely affected.

We may acquire properties subject to liabilities and without any recourse, or with only limited recourse, with respect to unknown liabilities. As a result, if a liability were asserted against us based upon those properties, we might have to pay substantial sums to settle it, which could adversely affect our cash flow. Unknown liabilities with respect to properties acquired might include:

· liabilities for clean-up of undisclosed environmental contamination;

· claims by tenants, vendors or other persons dealing with the former owners of the properties;

· liabilities incurred in the ordinary course of business; and

· claims for indemnification by general partners, directors, officers and others indemnified by the former owners of the properties.

Competition for acquisitions may reduce the number of acquisition opportunities available to us and increase the costs of those acquisitions.

We plan to continue to acquire properties as we are presented with attractive opportunities. We may face competition for acquisition opportunities with other investors, particularly private investors who can incur more leverage, and this competition may adversely affect us by subjecting us to the following risks:

· an inability to acquire a desired property because of competition from other well-capitalized real estate investors, including publicly traded and privately held REITs, institutional investment funds, investment banking firms and other real estate investors; and

· an increase in the purchase price for such acquisition property, in the event we are able to acquire such desired property.

We rely on four large properties for a significant portion of our revenue.

As of March 31, 2007, four of our properties, 420 Lexington Avenue, 1185 Avenue of the Americas, 1221 Avenue of the Americas and 1515 Broadway, accounted for approximately 25.2% of our portfolio annualized rent, including our share of joint venture annualized rent, and 1221 Avenue of the Americas alone accounted for approximately 7% of our portfolio annualized rent, including our share of joint venture annualized rent. Our revenue and cash available for distribution to our stockholders would be materially adversely affected if the ground lease for the 420 Lexington Avenue property were terminated for any reason or if one or all of these properties were materially damaged or destroyed. Additionally, our revenue and cash available for distribution to our stockholders would be materially adversely affected if our tenants at these properties experienced a downturn in their business which may weaken their financial condition and result in their failure to timely make rental payments, defaulting under their leases or filing for bankruptcy.

The continuing threat of terrorist attacks may adversely affect the value of our properties and our ability to generate cash flow.

There may be a decrease in demand for space in New York City because it is considered at risk for future terrorist attacks, and this decrease may reduce our revenues from property rentals. In the aftermath of a terrorist attack, tenants in the New York City area may choose to relocate their business to less populated, lower-profile areas of the United States that are not as likely to be targets of future terrorist activity. This in turn would trigger a decrease in the demand for space in the New York City area, which could increase vacancies in our properties and force us to lease our properties on less favorable terms. As a result, the value of our properties and the level of our revenues could materially decline.

A terrorist attack could cause insurance premiums to increase significantly.

We maintain “all-risk” property and rental value coverage (including coverage regarding the perils of flood, earthquake and terrorism) and liability insurance with limits in excess of $200.0 million per location. The property policies expire on December 31, 2007 and the liability policies expire on October 31, 2007. We now maintain two property insurance portfolios. The first portfolio maintains a blanket limit of $600.0 million per occurrence for the majority of the New York City properties in our portfolio with a sub-limit of $450.0 million for acts of terrorism. The second portfolio maintains a $600.0 million per occurrence, including terrorism, for the majority of the Suburban properties. The New York City portfolio incorporates our captive, Belmont Insurance Company, which we formed in an effort to stabilize, to some extent, the fluctuations of insurance market conditions. Belmont is licensed to write up to $100.0 million of coverage for us, but at this time is providing $50.0 million of terrorism coverage in excess of $100.0 million and is insuring a large deductible on the liability insurance with a $250,000 deductible per occurrence and a $2.4 million annual aggregate loss limit. We have secured an excess insurer to protect against catastrophic liability losses (above $250,000 / occurrence) and a stop loss for aggregate claims that exceed $2.4 million. We have retained a third party administrator to manage all claims within the deductible and we anticipate that direct management of liability claims will improve loss experience and ultimately lower the cost of liability insurance in future years. We have a 45% interest in the property at 1221 Avenue of the Americas, where we participate with The Rockefeller Group Inc., which carries a blanket policy providing $1.0 billion of “all-risk” property insurance, including terrorism coverage, and a 49.9% interest in the property at 100 Park Avenue, where we participate with Prudential, which carries a blanket policy of $500.0 million of “all-risk” property insurance, including terrorism coverage. We, together with Gramercy, own One Madison Avenue, for which insurance is provided by the tenant, Credit Suisse Securities (USA) LLC. Although we consider our insurance coverage to be appropriate, in the event of a major catastrophe, such as an act of terrorism, we may not have sufficient coverage to replace certain properties.

The Terrorism Risk Insurance Act, or TRIA, which was enacted in November 2002, was renewed on January 1, 2006. Congress extended TRIA, now called TRIEA (Terrorism Risk Insurance Extension Act) until December 31, 2007. The law extends the federal Terrorism Insurance Program that requires insurance companies to offer terrorism coverage and provides for compensation for insured losses resulting from acts of terrorism. Our debt instruments, consisting of mortgage loans secured by our properties (which are generally non-recourse to us), mezzanine loans, ground leases and our 2005 unsecured revolving credit facility and secured term loan, and unsecured bridge loan, contain customary covenants requiring us to maintain insurance. There can be no assurance that the lenders or ground lessors under these instruments will not take the position that a total or partial exclusion from “all-risk” insurance coverage for losses due to terrorist acts is a breach of these debt and ground lease instruments that allows the lenders or ground lessors to declare an event of default and accelerate repayment of debt or recapture of ground lease positions. In addition, if lenders insist on full coverage for these risks and prevail in asserting that we are required to maintain such coverage, it could result in substantially higher insurance premiums.

Our dependence on smaller and growth-oriented businesses to rent our office space could adversely affect our cash flow and results of operations.

Many of the tenants in our properties are smaller, growth-oriented businesses that may not have the financial strength of larger corporate tenants. Smaller companies generally experience a higher rate of failure than large businesses. Growth-oriented firms may also seek other office space, including Class A space, as they develop. Dependence on these companies could create a higher risk of tenant defaults, turnover and bankruptcies, which could adversely affect our distributable cash flow and results of operations.

Debt financing, financial covenants, degree of leverage, and increases in interest rates could adversely affect our economic performance.

Scheduled debt payments could adversely affect our results of operations.

The total principal amount of our outstanding consolidated indebtedness was approximately $4.9 billion as of March 31, 2007, consisting of none under our 2005 unsecured revolving credit facility, $500.0 million under our unsecured bridge loan, $2.0 billion under our unsecured notes, $200.0 million under our secured term loan, $100.0 million under our junior subordinated deferrable interest debentures and approximately $2.2 billion of non-recourse mortgage loans on eighteen of our properties. In addition, we could increase the amount of our outstanding indebtedness in the future, in part by borrowing under our 2005 unsecured revolving credit facility, which had $784.7 million available for draw as of March 31, 2007. Our 2005 unsecured revolving credit facility matures in September 2008. Our unsecured bridge loan matures in January 2010. Our secured term loan matures in May 2010. As of March 31, 2007, the total principal amount of non-recourse indebtedness outstanding at the joint venture properties was approximately $2.6 billion, of which our proportionate share was approximately $1.3 billion. Cash flow could be insufficient to pay distributions at expected levels and meet the payments of

principal and interest required under our current mortgage indebtedness, credit facility, term loan, bridge loan, debentures and indebtedness outstanding at our joint venture properties.

If we are unable to make payments under our unsecured credit facility, our secured term loan, and our unsecured bridge loan, all amounts due and owing at such time shall accrue interest at a rate equal to 4% higher than the rate at which each such loan was made. If a property is mortgaged to secure payment of indebtedness and we are unable to meet mortgage payments, the mortgagee could foreclose on the property, resulting in loss of income and asset value. Foreclosure on mortgaged properties or an inability to make scheduled payments under our secured term loan, unsecured credit facility and our unsecured bridge loan, would have a negative impact on our financial condition and results of operations.

We may not be able to refinance existing indebtedness, which in all cases requires substantial principal payments at maturity. In 2007, approximately $33.2 million and $892.3 million of debt on our consolidated properties and our unconsolidated joint venture properties, respectively, will mature. At the present time we intend to exercise extension options or refinance the debt associated with our properties on or prior to their respective maturity dates. If any principal payments due at maturity cannot be refinanced, extended or paid with proceeds of other capital transactions, such as new equity capital, our cash flow will not be sufficient in all years to repay all maturing debt. At the time of refinancing, prevailing interest rates or other factors, such as the possible reluctance of lenders to make commercial real estate loans may result in higher interest rates. Increased interest expense on the refinanced debt would adversely affect cash flow and our ability to service debt and make distributions to stockholders.

Financial covenants could adversely affect our ability to conduct our business.

The mortgages on our properties contain customary negative covenants that limit our ability to further mortgage the property, to enter into new leases or materially modify existing leases, and to discontinue insurance coverage. In addition, our 2005 unsecured revolving credit facility contains customary restrictions and requirements on our method of operations. Our 2005 unsecured revolving credit facility and secured term loan, unsecured bridge loan and unsecured bonds also require us to maintain designated ratios of total debt-to-assets, debt service coverage and unencumbered assets-to-unsecured debt. Restrictions on our ability to conduct business could adversely affect our results of operations and our ability to make distributions to stockholders.

Rising interest rates could adversely affect our cash flow.

Advances under our 2005 unsecured revolving credit facility, secured term loan, unsecured bridge loan and certain property-level mortgage debt bear interest at a variable rate. These variable rate borrowings totaled approximately $608.3 million at March 31, 2007. In addition, we could increase the amount of our outstanding variable rate debt in the future, in part by borrowing under our 2005 unsecured revolving credit facility, which had $784.7 million available for draw as of March 31, 2007. Borrowings under our 2005 unsecured revolving credit facility bear interest at a spread equal to the 30-day LIBOR, plus 110 basis points. Borrowings under our unsecured bridge loan and our secured term loan bear interest at spreads equal to the 30-day LIBOR plus 110 and 125 basis points, respectively. As of March 31, 2007, borrowings under the 2005 unsecured revolving credit facility, secured term loan, unsecured bridge loan and junior subordinated deferrable interest debentures totaled none, $200.0 million, $500.0 million and $100.0 million, respectively, and bore interest at 6.42%, 5.96%, 6.42%, and 5.61%, respectively. We may incur indebtedness in the future that also bears interest at a variable rate or may be required to refinance our debt at higher rates. Accordingly, increases in interest rates above that which we anticipated based upon historical trends could adversely affect our ability to continue to make distributions to stockholders. At March 31, 2007, a hypothetical 100 basis point increase in interest rates along the entire interest rate curve would increase our annual interest costs by approximately $8.9 million and would increase our share of joint venture annual interest costs by approximately $6.9 million.

Failure to hedge effectively against interest rate changes may adversely affect results of operations.

The interest rate hedge instruments we use to manage some of our exposure to interest rate volatility involve risk, such as the risk that counterparties may fail to honor their obligations under these arrangements. In addition, these arrangements may not be effective in reducing our exposure to interest rate changes. Failure to hedge effectively against interest rate changes may adversely affect our results of operations.

Our policy of no limitation on debt could adversely affect our cash flow.

Our organizational documents do not contain any limitation on the amount of indebtedness we may incur. As of March 31, 2007, assuming the conversion of all outstanding units of the operating partnership into shares of our common stock, our combined debt-to-market capitalization ratio, including our share of joint venture debt of $1.3 billion, was approximately 41.9%. However, our policy is to incur debt only if upon a conversion our consolidated debt to market capitalization ratio would be 60.0% or less. Our board of directors can alter or eliminate this policy and may do so if our board of directors determines that this action is in the best interests of our business. If this policy is changed and we become more highly leveraged, an increase in debt service could adversely affect cash available for distribution to stockholders and could increase the risk of default on our indebtedness. In addition, any change that increases our debt to market capitalization percentage could be viewed negatively by investors. As a result, our share price could decrease.

We have established our debt policy relative to the total market capitalization of our business rather than relative to the book value of our assets. We use total market capitalization because we believe that the book value of our assets, which to a large extent is the depreciated original cost of our properties, and our primary tangible assets, does not accurately reflect our ability to borrow and to meet debt service requirements. Our market capitalization, however, is more variable than book value, and does not necessarily reflect the fair market value of our assets at all times. We also will consider factors other than market capitalization in making decisions regarding the incurrence of indebtedness, such as the purchase price of properties to be acquired with debt financing, the estimated market value of our properties upon refinancing and the ability of particular properties and our business as a whole to generate cash flow to cover expected debt service.

Structured finance investments could cause us to incur expenses, which could adversely affect our results of operations.

We owned mezzanine loans, junior participations and preferred equity interests in eighteen properties with an aggregate book value of approximately $688.3 million at March 31, 2007. Such investments may or may not be recourse obligations of the borrower and are not insured or guaranteed by governmental agencies or otherwise. In the event of a default under these obligations, we may have to realize upon our collateral and thereafter make substantial improvements or repairs to the underlying real estate in order to maximize the property’s investment potential. Borrowers may contest enforcement of foreclosure or other remedies, seek bankruptcy protection against such enforcement and/or bring claims for lender liability in response to actions to enforce their obligation to us. Relatively high loan-to-value ratios and declines in the value of the property may prevent us from realizing an amount equal to our investment upon foreclosure or realization. In addition, under the origination agreement with Gramercy, we are precluded from making certain types of structured finance investments.

Joint investments could be adversely affected by our lack of sole decision-making authority and reliance upon a co-venturer’s financial condition.

We co-invest with third parties through partnerships, joint ventures, co-tenancies or other entities, acquiring non-controlling interests in, or sharing responsibility for managing the affairs of, a property, partnership, joint venture, co-tenancy or other entity. Therefore, we will not be in a position to exercise sole decision-making authority regarding that property, partnership, joint venture or other entity. Investments in partnerships, joint ventures, or other entities may involve risks not present were a third party not involved, including the possibility that our partners, co-tenants or co-venturers might become bankrupt or otherwise fail to fund their share of required capital contributions. Additionally, our partners or co-venturers might at any time have economic or other business interests or goals, which are inconsistent with our business interests or goals. These investments may also have the potential risk of impasses on decisions such as a sale, because neither we nor the partner, co-tenant or co-venturer would have full control over the partnership or joint venture. Consequently, actions by such partner, co-tenant or co-venturer might result in subjecting properties owned by the partnership or joint venture to additional risk. In addition, we may in specific circumstances be liable for the actions of our third-party partners, co-tenants or co-venturers. As of March 31, 2007, our unconsolidated joint ventures owned eight properties and we had an aggregate cost basis in the joint ventures totaling approximately $744.0 million. As of March 31, 2007, our share of joint venture debt totaled approximately $1.3 billion.

Our joint venture agreements contain terms in favor of our partners that may have an adverse effect on the value of our investments in the joint ventures.

Each of our joint venture agreements has been individually negotiated with our partner in the joint venture and, in some cases, we have agreed to terms that are favorable to our partner in the joint venture. For example, our partner may be entitled to a specified portion of the profits of the joint venture before we are entitled to any portion of such profits and our partner may have rights to buy our interest in the joint venture, to force us to buy the partner’s interest in the joint venture or to compel the sale of the property owned by such joint venture. These rights may permit our partner in a particular joint venture to obtain a greater benefit from the value or profits of the joint venture than us, which may have an adverse effect on the value of our investment in the joint venture and on our financial condition and results of operations. We may also enter into similar arrangements in the future.

We are subject to possible environmental liabilities and other possible liabilities.

We are subject to various federal, state and local environmental laws. These laws regulate our use, storage, disposal and management of hazardous substances and wastes and can impose liability on property owners or operators for the clean-up of certain hazardous substances released on a property and any associated damage to natural resources without regard to whether the release was legal or whether it was caused by the property owner or operator. The presence of hazardous substances on our properties may adversely affect occupancy and our ability to develop or sell or borrow against those properties. In addition to potential liability for clean-up costs, private plaintiffs may bring claims for personal injury, property damage or for similar reasons. Various laws also impose liability for the clean-up of contamination at any facility (e.g., a landfill) to which we have sent hazardous substances for treatment or disposal, without regard to whether the materials were transported, treated and disposed in accordance with law.

Our properties may be subject to other risks relating to current or future laws including laws benefiting disabled persons, and other state or local zoning, construction or other regulations. These laws may require significant property modifications in the future for which we may

not have budgeted and could result in fines being levied against us. The occurrence of any of these events could have an adverse impact on our cash flows and ability to make distributions to stockholders.

We may incur significant costs complying with the Americans with Disabilities Act and similar laws.

Under the Americans with Disabilities Act, or ADA, all public accommodations must meet federal requirements related to access and use by disabled persons. Additional federal, state and local laws also may require modifications to our properties, or restrict our ability to renovate our properties. We have not conducted an audit or investigation of all of our properties to determine our compliance. If one or more of our properties is not in compliance with the ADA or other legislation, then we would be required to incur additional costs to bring the property into compliance. We cannot predict the ultimate amount of the cost of compliance with ADA or other legislation. If we incur substantial costs to comply with the ADA and any other legislation, our financial condition, results of operations and cash flow and/or ability to satisfy our debt service obligations and to pay dividends to our stockholders could be adversely affected.

Our charter documents and applicable law may hinder any attempt to acquire us, which could discourage takeover attempts and prevent our stockholders from receiving a premium over the market price of our stock.

Provisions of our articles of incorporation and bylaws could inhibit changes in control.

A change of control of our company could benefit stockholders by providing them with a premium over the then-prevailing market price of the stock. However provisions contained in our articles of incorporation and bylaws may delay or prevent a change in control of our company. These provisions, discussed more fully below, are:

· staggered board of directors;

· ownership limitations for tax purposes;

· the board of director’s ability to issue additional common stock and preferred stock without stockholder approval; and

· stockholder rights plan.

Our board of directors is staggered into three separate classes.

The board of directors of our company is divided into three classes. The terms of the class I, class II and class III directors expire in 2007, 2008 and 2009, respectively. Our staggered board may deter changes in control because of the increased time period necessary for a third party to acquire control of the board.

We have a share ownership limit for REIT tax purposes.

To remain qualified as a REIT for federal income tax purposes, not more than 50% in value of our outstanding capital stock may be owned by five or fewer individuals at any time during the last half of any taxable year. For this purpose, stock may be “owned” directly, as well as indirectly under certain constructive ownership rules, including, for example, rules that attribute stock held by one family member to another family member. To avoid violating this rule regarding share ownership limitations and maintain our REIT qualification, our articles of incorporation prohibit ownership by any single stockholder of more than 9.0% in value or number of shares of our common stock. Limitations on the ownership of preferred stock may also be imposed by us.

The board of directors has the discretion to raise or waive this limitation on ownership for any stockholder if deemed to be in our best interest. To obtain a waiver, a stockholder must present the board and our tax counsel with evidence that ownership in excess of this limit will not affect our present or future REIT status.

Absent any exemption or waiver, stock acquired or held in excess of the limit on ownership will be transferred to a trust for the exclusive benefit of a designated charitable beneficiary, and the stockholder’s rights to distributions and to vote would terminate. The stockholder would be entitled to receive, from the proceeds of any subsequent sale of the shares transferred to the charitable trust, the lesser of: the price paid for the stock or, if the owner did not pay for the stock, the market price of the stock on the date of the event causing the stock to be transferred to the charitable trust; and the amount realized from the sale.

This limitation on ownership of stock could delay or prevent a change in control.

We have a stockholder rights plan.

We adopted a stockholder rights plan which provides, among other things, that when specified events occur, our stockholders will be entitled to purchase from us a newly created series of junior preferred shares, subject to our ownership limit described above. The preferred share purchase rights are triggered by the earlier to occur of (1) ten days after the date of a public announcement that a person or group acting in concert has acquired, or obtained the right to acquire, beneficial ownership of 17% or more of our outstanding shares of common stock or (2) ten business days after the commencement of or announcement of an intention to make a tender offer or exchange offer, the consummation of which would result in the acquiring person becoming the beneficial owner of 17% or more of our outstanding common stock. The preferred share purchase rights would cause substantial dilution to a person or group that attempts to acquire us on terms not approved by our board of directors.

Maryland takeover statutes may prevent a change of control of our company, which could depress our stock price.

Under Maryland law, “business combinations” between a Maryland corporation and an interested stockholder or an affiliate of an interested stockholder are prohibited for five years after the most recent date on which the interested stockholder becomes an interested stockholder. These business combinations include a merger, consolidation, share exchange, or, in circumstances specified in the statute, an asset transfer or issuance or reclassification of equity securities. An interested stockholder is defined as:

· any person who beneficially owns 10% or more of the voting power of the corporation’s outstanding shares; or

· an affiliate or associate of the corporation who, at any time within the two-year period prior to the date in question, was the beneficial owner of 10% or more of the voting power of the then outstanding voting stock of the corporation.

· A person is not an interested stockholder under the statute if the board of directors approves in advance the transaction by which he otherwise would have become an interested stockholder.

After the five-year prohibition, any business combination between the Maryland corporation and an interested stockholder generally must be recommended by the board of directors of the corporation and approved by the affirmative vote of at least:

· 80% of the votes entitled to be cast by holders of outstanding shares of voting stock of the corporation, voting together as a single group; and

· two-thirds of the votes entitled to be cast by holders of voting stock of the corporation other than shares held by the interested stockholder with whom or with whose affiliate the business combination is to be effected or held by an affiliate or associate of the interested stockholder.

The business combination statute may discourage others from trying to acquire control of us and increase the difficulty of consummating any offer, including potential acquisitions that might involve a premium price for our common stock or otherwise be in the best interest of our stockholders.

In addition, Maryland law provides that “control shares” of a Maryland corporation acquired in a “control share acquisition” will have no voting rights except to the extent approved by a vote of two-thirds of the votes entitled to be cast on the matter, excluding shares of stock owned by the acquiror, by officers of the corporation or by directors who are employees of the corporation, under the Maryland Control Share Acquisition Act. “Control shares” means voting shares of stock that, if aggregated with all other shares of stock owned by the acquiror or in respect of which the acquiror is able to exercise or direct the exercise of voting power (except solely by virtue of a revocable proxy), would entitle the acquiror to exercise voting power in electing directors within one of the following ranges of voting power: (i) one-tenth or more but less than one-third, (ii) one-third or more but less than a majority, or (iii) a majority or more of all voting power. A “control share acquisition” means the acquisition of ownership of, or the power to direct the exercise of voting power with respect to, issued and outstanding control shares, subject to certain exceptions.

We have opted out of these provisions of the Maryland General Corporation Law, or the MGCL, with respect to business combinations and control share acquisitions by resolution of our board of directors and a provision in our bylaws, respectively. However, in the future, our board of directors may reverse its decision by resolution and elect to opt in to the MGCL’s business combination provisions, or amend our bylaws and elect to opt in to the MGCL’s control share provisions.

Additionally, Title 8, Subtitle 3 of the MGCL permits our board of directors, without stockholder approval and regardless of what is provided in our charter or bylaws, to implement takeover defenses, some of which we do not have. Such takeover defenses, if implemented, may have the effect of inhibiting a third party from making us an acquisition proposal or of delaying, deferring or preventing a change in our control under circumstances that otherwise could provide you with an opportunity to realize a premium over the then-current market price.

Future issuances of common stock and preferred stock could dilute existing stockholders’ interests.

Our articles of incorporation authorize our board of directors to issue additional shares of common stock and preferred stock without stockholder approval. Any such issuance could dilute our existing stockholders’ interests. Also, any future series of preferred stock may have voting provisions that could delay or prevent a change of control.

Changes in market conditions could adversely affect the market price of our common stock.

As with other publicly traded equity securities, the value of our common stock depends on various market conditions, which may change from time to time. Among the market conditions that may affect the value of our common stock are the following:

· the extent of your interest in us;

· the general reputation of REITs and the attractiveness of our equity securities in comparison to other equity securities, including securities issued by other real estate-based companies;

· our financial performance; and

· general stock and bond market conditions.

The market value of our common stock is based primarily upon the market’s perception of our growth potential and our current and potential future earnings and cash dividends. Consequently, our common stock may trade at prices that are higher or lower than our net asset value per share of common stock. If our future earnings or cash dividends are less than expected, it is likely that the market price of our common stock will diminish.

Market interest rates may have an effect on the value of our common stock.

If market interest rates go up, prospective purchasers of shares of our common stock may expect a higher distribution rate on our common stock. Higher market interest rates would not, however, result in more funds for us to distribute and, to the contrary, would likely increase our borrowing costs and potentially decrease funds available for distribution. Thus, higher market interest rates could cause the market price of our common stock to go down.

There are potential conflicts of interest between us and Mr. Green.

There is a potential conflict of interest relating to the disposition of the property contributed to us by Stephen L. Green, and his family. Mr. Green serves as the chairman of our board of directors and is an executive officer. As part of our formation, Mr. Green contributed appreciated property, with a net book value of $73.5 million, to the operating partnership in exchange for units of limited partnership interest in the operating partnership. He did not recognize any taxable gain as a result of the contribution. The operating partnership, however, took a tax basis in the contributed property equal to that of the contributing unitholder. The fair market value of the property contributed by him exceeded his tax basis by approximately $34.0 million at the time of contribution. The difference between fair market value and tax basis at the time of contribution represents a built-in gain. If we sell a property in a transaction in which a taxable gain is recognized, for tax purposes the built-in gain would be allocated solely to him and not to us. As a result, Mr. Green has a conflict of interest if the sale of a property, which he contributed, is in our best interest but not his.

There is a potential conflict of interest relating to the refinancing of indebtedness specifically allocated to Mr. Green. Mr. Green would recognize gain if he were to receive a distribution of cash from the operating partnership in an amount that exceeds his tax basis in his partnership units. His tax basis includes his share of debt, including mortgage indebtedness, owed by our operating partnership. If our operating partnership were to retire such debt, then he would experience a decrease in his share of liabilities, which, for tax purposes, would be treated as a distribution of cash to him. To the extent the deemed distribution of cash exceeded his tax basis, he would recognize gain.

Limitations on our ability to sell or reduce the indebtedness on specific mortgaged properties could adversely affect the value of the stock.

We have agreed to restrictions relating to future transactions involving 673 First Avenue and 470 Park Avenue South. During the period of time that these restrictions apply, our ability to manage or use these properties in a manner that is in our overall best interests may be impaired. In particular, these restrictions could preclude us from participating in major transactions otherwise favorable to us if a

disposition of these restricted assets is required. These restrictions may also inhibit a change in control of our company even though a disposition or change in control might be in the best interests of the stockholders.

Specifically, we have agreed not to sell our interest in these properties until August 20, 2009 without the approval of unitholders holding at least 75% of the units issued in consideration for these properties. The current gross carrying value of the commercial real estate of these properties totaled approximately $88.3 million at March 31, 2007. We have also agreed not to reduce the mortgage indebtedness (approximately $33.6 million at March 31, 2007), other than pursuant to scheduled amortization, on 673 First Avenue until one year prior to its maturity date without the same consent. In addition, we are obligated to use commercially reasonable efforts to refinance this mortgage prior to its maturity date in an amount not less than the principal amount outstanding on the maturity date. With respect to 673 First Avenue, Mr. Green controls at least 75% of the units whose approval is necessary. With respect to 470 Park Avenue South, Mr. Green controls at least 65% of the units whose approval is necessary. Finally, during this period, we may not incur debt secured by any of these properties if the amount of our new debt would exceed the greater of 75% of the value of the property securing the debt or the amount of existing debt being refinanced plus associated costs. The maturity date for the mortgage loan for 673 First Avenue is February 11, 2013.

In addition, on May 15, 2002, we acquired the property located at 1515 Broadway, New York, New York. Under a tax protection agreement established to protect the limited partners of the partnership that transferred 1515 Broadway to us, we have agreed not to take certain action that would adversely affect the limited partners’ tax positions before December 31, 2011. We also acquired the property located at 220 East 42nd Street, New York, New York, on February 13, 2003. We have agreed not to take certain action that would adversely affect the tax positions of certain of the partners who held interests in this property prior to the acquisition for a period of seven years, after the acquisition. We also acquired the property located at 625 Madison Avenue, New York, New York, on October 19, 2004 and have agreed not to take certain action that would adversely affect the tax positions of certain of the partners who held interests in this property prior to the acquisition for a period of seven years after the acquisition.

In addition, pursuant to the Reckson Merger we acquired certain properties located in Valhalla, New York and succeeded to Reckson’s agreement not to take certain actions prior to April 21, 2013 that would adversely affect the tax positions of certain of the partners who held interests in those properties prior to their contribution to Reckson.

In connection with future acquisitions of interests in properties, we may agree to similar restrictions on our ability to sell or refinance the acquired properties with similar potential adverse consequences.

We face potential conflicts of interest.

Members of management may have a conflict of interest over whether to enforce terms of agreements with entities in which senior management, directly or indirectly, has an interest.

Two entities owned by one of Mr. Green’s sons, First Quality Maintenance, L.P. and Classic Security LLC, currently provide cleaning, exterminating and security services to all of our office properties, with the exception of cleaning services at one property. Our company and our tenants accounted for approximately 13.4% of First Quality Maintenance, L.P.’s 2006 total revenue and 39.7% of Classic Security LLC’s 2006 total revenue. Bright Star Courier, LLC, a messenger service company owned by one of Mr. Green’s sons, has provided messenger services at of our properties since May 1, 2002. We accounted for approximately 28.8% of Bright Star Courier, LLC’s 2006 total revenue. In addition, Onyx Restoration Works, a restoration company owned by one of Mr. Green’s sons, has provided restoration services at all of our properties since March 2005. We accounted for approximately 62.8% of Onyx Restoration Works’ 2006 total revenue. While the contracts pursuant to which these services are provided are reviewed by our board of directors, they are not the result of arm’s length negotiations and, therefore, there can be no assurance that the terms and conditions are not less favorable than those which could be obtained from third parties providing comparable services. In addition, to the extent that we choose to enforce our rights under any of these agreements, we may determine to pursue available remedies, such as actions for damages or injunctive relief, less vigorously than we otherwise might because of our desire to maintain our ongoing relationship with the individual involved.

Members of management may have a conflict of interest over whether to enforce terms of senior management’s employment and noncompetition agreements.

Stephen Green, Marc Holliday, Gregory Hughes, Andrew Levine and Andrew Mathias entered into employment and noncompetition agreements with us pursuant to which they have agreed not to actively engage in the acquisition, development or operation of office real estate in the New York City metropolitan area. For the most part these restrictions apply to the executive both during his employment and for a period of time thereafter. Each executive is also prohibited from otherwise disrupting or interfering with our business through the solicitation of our employees or clients or otherwise. To the extent that we choose to enforce our rights under any of these agreements, we may determine to pursue available remedies, such as actions for damages or injunctive relief, less vigorously than we otherwise might because of our desire to maintain our ongoing relationship with the individual involved. Additionally, the non-competition provisions of these agreements despite being limited in scope and duration, could be difficult to enforce, or may be subject to limited enforcement, should litigation arise over them in the future. Mr. Green has interests in two properties in Manhattan, which are exempt from the non-competition provisions of his employment and non-competition agreement.

Our failure to qualify as a REIT would be costly.

We believe we have operated in a manner to qualify as a REIT for federal income tax purposes and intend to continue to so operate. Many of these requirements, however, are highly technical and complex. The determination that we are a REIT requires an analysis of factual matters and circumstances. These matters, some of which may not be totally within our control, can affect our qualification as a REIT. For example, to qualify as a REIT, at least 95% of our gross income must come from designated sources that are listed in the REIT tax laws. We are also required to distribute to stockholders at least 90% of our REIT taxable income excluding capital gains. The fact that we hold our assets through the operating partnership and its subsidiaries further complicates the application of the REIT requirements. Even a technical or inadvertent mistake could jeopardize our REIT status. Furthermore, Congress and the Internal Revenue Service, which we refer to as the IRS, might make changes to the tax laws and regulations, and the courts might issue new rulings that make it more difficult, or impossible, for us to remain qualified as a REIT.

If we fail to qualify as a REIT, we would be subject to federal income tax at regular corporate rates. Also, unless the IRS grants us relief under specific statutory provisions, we would remain disqualified as a REIT for four years following the year we first failed to qualify. If we failed to qualify as a REIT, we would have to pay significant income taxes and would therefore have less money available for investments or for distributions to stockholders. This would likely have a significant adverse effect on the value of our securities. In addition, the REIT tax laws would no longer require us to make any distributions to stockholders.

We would incur adverse tax consequences in Reckson failed to qualify as a REIT.

We have assumed that Reckson has qualified as a REIT for United States federal income tax purposes and that we will continue to be able to qualify as a REIT following the Reckson Merger. However, if Reckson failed to qualify as a REIT, we generally would have succeeded to significant tax liabilities (including the significant tax liability that would result from a deemed sale of assets by Reckson pursuant to the Reckson Merger).

Previously enacted tax legislation reduces tax rates for dividends paid by non-REIT corporations.

Under certain previously enacted tax legislation, the maximum tax rate on dividends to individuals has generally been reduced from 38.6% to 15% (from January 1, 2003 through December 31, 2008). The reduction in rates on dividends is generally not applicable to dividends paid by a REIT except in limited circumstances that we do not contemplate. Although this legislation will not adversely affect the taxation of REITs or dividends paid by REITs, the favorable treatment of regular corporate dividends could cause investors who are individuals to consider stock of non-REIT corporations that pay dividends as relatively more attractive than stocks of REITs. It is not possible to predict whether such a change in perceived relative value will occur or what the effect, if any, this legislation will have on the market price of our stock.

We are dependent on external sources of capital.

Because of distribution requirements imposed on us to qualify as a REIT, it is not likely that we will be able to fund all future capital needs, including acquisitions, from income from operations. We therefore will have to rely on third-party sources of capital, which may or may not be available on favorable terms or at all. Our access to third-party sources of capital depends on a number of things, including the market’s perception of our growth potential and our current and potential future earnings. In addition, we anticipate having to raise money in the public equity and debt markets with some regularity, and our ability to do so will depend upon the general conditions prevailing in these markets. At any time conditions may exist which effectively prevent us, and REITs in general, from accessing these markets. Moreover, additional equity offerings may result in substantial dilution of our stockholders’ interests, and additional debt financing may substantially increase our leverage.

We face significant competition for tenants.

The leasing of real estate is highly competitive. The principal means of competition are rent charged, location, services provided and the nature and condition of the facility to be leased. We directly compete with all lessors and developers of similar space in the areas in which our properties are located. Demand for retail space has been impacted by the recent bankruptcy of a number of retail companies and a general trend toward consolidation in the retail industry, which could adversely affect the ability of our company to attract and retain tenants.

Our commercial office properties are concentrated in highly developed areas of midtown Manhattan and certain Suburban central business districts, or CBD’s. Manhattan is the largest office market in the United States. The number of competitive office properties in Manhattan and CBD’s in which our Suburban properties are located (which may be newer or better located than our properties) could have a material adverse effect on our ability to lease office space at our properties, and on the effective rents we are able to charge.

Loss of our key personnel could harm our operations.

We are dependent on the efforts of Stephen L. Green, the chairman of our board of directors and an executive officer, Marc Holliday, our chief executive officer, Andrew Mathias, our president and chief investment officer and Gregory F. Hughes, our chief operating and financial officer. A loss of the services of either of these individuals could adversely affect our operations.

Our business and operations would suffer in the event of system failures.

Despite system redundancy, the implementation of security measures and the existence of a Disaster Recovery Plan for our internal information technology systems, our systems are vulnerable to damages from any number of sources, including computer viruses,

unauthorized access, energy blackouts, natural disasters, terrorism, war and telecommunication failures. Any system failure or accident that causes interruptions in our operations could result in a material disruption to our business. We may also incur additional costs to remedy damages caused by such disruptions.

Compliance with changing regulation of corporate governance and public disclosure may result in additional expenses, affect our operations and affect our reputation.

Changing laws, regulations and standards relating to corporate governance and public disclosure, including the Sarbanes-Oxley Act of 2002 and new SEC regulations and New York Stock Exchange rules, are creating uncertainty for public companies. These new or changed laws, regulations and standards are subject to varying interpretations in many cases due to their lack of specificity, and as a result, their application in practice may evolve over time as new guidance is provided by regulatory and governing bodies, which could result in continuing uncertainty regarding compliance matters and higher costs necessitated by ongoing revisions to disclosure and governance practices. We are committed to maintaining high standards of corporate governance and public disclosure. As a result, our efforts to comply with evolving laws, regulations and standards have resulted in, and are likely to continue to result in, increased general and administrative expenses and a diversion of management time and attention from revenue-generating activities to compliance activities. In particular, our efforts to comply with Section 404 of the Sarbanes-Oxley Act of 2002 and the related regulations regarding our required assessment of our internal controls over financial reporting and our external auditors’ audit of that assessment has required the commitment of significant financial and managerial resources. In addition, it has become more difficult and more expensive for us to obtain director and officer liability insurance. We expect these efforts to require the continued commitment of significant resources. Further, our directors, chief executive officer and chief financial officer could face an increased risk of personal liability in connection with the performance of their duties. As a result, we may have difficulty attracting and retaining qualified directors and executive officers, which could harm our business. If our efforts to comply with new or changed laws, regulations and standards differ from the activities intended by regulatory or governing bodies due to ambiguities related to practice, our reputation may be harmed.

ITEM 2.	UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

	In March 2007, our Board of Directors approved a stock purchase plan under which we can buy up to $300.0 million of our common stock. This plan will expire on December 31, 2008. In April 2007, we purchased approximately 16,000 shares of our common stock at an average price of $132.48 per share.
