Second Supplemental Indenture related to 4.50% Senior Notes due 2022

On November 15, 2012, SL Green Realty Corp. (the “Company”), SL Green Operating Partnership, L.P. (“SL Green OP”) and Reckson Operating Partnership, L.P. (“Reckson”), as co-obligors (collectively, the “Co-Obligors”), issued $200.0 million aggregate principal amount of 4.50% Senior Notes due 2022 (the “Notes”) in a public offering pursuant to the Co-Obligors’ Registration Statement on Form S-3 (No. 333-163914) filed with the Securities and Exchange Commission (the “Commission”), as amended.  Net proceeds from the offering of the Notes, after underwriting discounts and the Co-Obligors’ estimated fees and expenses, are expected to be approximately $197.7 million.  The Notes were issued pursuant to an indenture, dated as of August 5, 2011 (the “Base Indenture”), among the Co-Obligors and The Bank of New York Mellon, as trustee (the “Trustee”), as amended by the second supplemental indenture (the “Second Supplemental Indenture” and, together with the Base Indenture, the “Indenture”), dated as of November 15, 2012, among the Co-Obligors and the Trustee and the related 4.50% Senior Note due 2022 (the “4.50% Note”) of the Co-Obligors.  Reckson is a wholly-owned subsidiary of the Company’s operating partnership, SL Green OP.  The description of the Indenture and the related form of 4.50% Note contained in this report is qualified in its entirety by reference to the complete text of the Base Indenture, the Second Supplemental Indenture and the form of 4.50% Note.  The Base Indenture was previously filed with the Commission as Exhibit 4.1 to the Current Report on Form 8-K filed by the Co-Obligors on August 5, 2011.  Copies of the Second Supplemental Indenture and the 4.50% Note are filed as Exhibits 4.1 and 4.2, respectively, to this report and are incorporated herein by reference.

The Notes mature on December 1, 2022.  The Notes bear interest at a rate of 4.50% per annum, computed on the basis of a 360-day year composed of twelve 30-day months and payable on June 1 and December 1 of each year, beginning on June 1, 2013.

The Notes are the unsecured unsubordinated obligations of the Co-Obligors and rank equally with each entity’s existing and future unsecured unsubordinated indebtedness.  The Indenture contains covenants that, among other things, restrict the ability of Reckson and its subsidiaries’ to incur additional indebtedness and encumber assets.  These covenants are subject to a number of important limitations and exceptions.  The Company and SL Green OP are not subject to such restrictions.

The Co-Obligors have the option to redeem all or a part of the Notes, at any time or from time to time, at a redemption price equal to 100% of the principal amount of the Notes redeemed, plus a “make-whole” premium, and accrued and unpaid interest, if any, to the applicable redemption date.  If the Notes are redeemed on or after September 1, 2022, the redemption price for the Notes will equal 100% of the principal amount of the Notes, plus accrued interest thereon to the redemption date.

The Indenture provides for customary events of default.  In the case of an event of default arising from specified events of bankruptcy or insolvency, all outstanding Notes will become due and payable immediately without further action or notice.  If any other event of default under the Indenture occurs or is continuing, the Trustee or holders of at least 25% in principal amount of the then outstanding Notes may declare all the Notes to be due and payable immediately.

Underwriting Agreement

On November 9, 2012, the Co-Obligors entered into an Underwriting Agreement (the “Underwriting Agreement”) with Wells Fargo Securities, LLC, as representative of the underwriters listed therein, relating to the sale by the Co-Obligors of $200.0 million aggregate principal amount of the Notes.
