(b)           In addition to the limitation set forth in subsection (a) of this Section 5.1, the Operating Partnership will not, and will not permit any Subsidiary to, incur any Indebtedness, other than Permitted Debt, if, for the period consisting of the four consecutive fiscal quarters most recently ended prior to the date on which such additional Indebtedness is to be incurred, the ratio of Consolidated Income Available for Debt Service to the Annual Service Charge shall have been less than 1.5 to 1, on a pro forma basis after giving effect to the incurrence of such Indebtedness and to the application of the proceeds therefrom, and calculated on the assumption that (i) such Indebtedness and any other Indebtedness incurred by the Operating Partnership or its Subsidiaries since the first day of such four-quarter period and the application of the proceeds therefrom, including to refinance other Indebtedness, had occurred at the beginning of such period, (ii) the repayment or retirement of any other Indebtedness by the Operating Partnership or its Subsidiaries since the first day of such four-quarter period had been incurred, repaid or retained at the beginning of such period (except that, in making such computation, the amount of Indebtedness under any revolving credit facility shall be computed based upon the average daily balance of such Indebtedness under such credit facility during such period), (iii) any income earned as a result of any increase in Adjusted Total Assets since the end of such four-quarter period had been earned, on an annualized basis, for such period, and (iv) in the case of an acquisition or disposition by the Operating Partnership or any of its Subsidiaries of any asset or group of assets since the first day of such four-quarter period, including, without limitation, by merger, stock purchase or sale, or asset purchase or sale, such acquisition or disposition or any related repayment of Indebtedness had occurred as of the first day of such period with the appropriate adjustments with respect to such acquisition or disposition being included in such pro forma calculation of Consolidated Income Available for Debt Service to the Annual Service Charge.

(c)           In addition to the limitations set forth in subsections (a) and (b) of this Section 5.1, the Operating Partnership will not, and will not permit any Subsidiary to, incur any Indebtedness secured by any Lien of any kind upon any of the property of the Operating Partnership or any of its Subsidiaries (the “Secured Debt”) if, immediately after giving effect to the incurrence of such additional

Secured Debt, the aggregate principal amount of all outstanding Secured Debt of the Operating Partnership, and of its Subsidiaries determined at the applicable proportionate interest of the Operating Partnership in each such Subsidiary, is greater than 40% of the Adjusted Total Assets.

Section 5.2            Maintenance of Total Unencumbered Assets.

The Operating Partnership will maintain Total Unencumbered Assets of not less than 150% of the aggregate principal amount of all outstanding Unsecured Debt.

Section 5.3            Provision of Financial Information.

(a)           Whether or not SL Green or the Operating Partnership is subject to the reporting requirements of Section 13 or 15(d) of the Exchange Act, SL Green and the Operating Partnership must, and solely to the extent that SL Green OP is subject to the requirements of Section 13 or 15(d) of the Exchange Act, SL Green OP will, provide the Trustee and holders within 15 days after filing, or in the event no such filing is required, within 15 days after the end of the time periods specified in those sections with all quarterly and annual financial information that would be required to be contained in a filing with the SEC on Forms 10-Q and 10-K if SL Green, SL Green OP (if applicable) or the Operating Partnership were required to file such forms; provided that, the foregoing delivery requirements shall be deemed satisfied if the foregoing materials are available on the SEC’s EDGAR system or on SL Green’s, SL Green OP’s or the Operating Partnership’s web site within the applicable time period.

(b)           In addition, whether or not required by the SEC, SL Green and the Operating Partnership will, and SL Green OP will, solely to the extent that SL Green OP is subject to the requirements of Section 13 or 15(d) of the Exchange Act, file a copy of all of the information and reports referred to above with the SEC for public availability within the time periods specified in the SEC’s rules and regulations.

TRUSTEE’S CERTIFICATE OF AUTHENTICATION

This is one of the Notes of the series designated therein referred to in the within-mentioned Indenture.

[REVERSE SIDE OF NOTE]

4.50% Senior Notes due 2022

Indenture.  This Note is one of a duly authorized issue of securities of the Co-Obligors, issued and to be issued in one or more series under an Indenture, dated as of August 5, 2011, as supplemented by a First Supplemental Indenture, dated as of August 5, 2011, and a Second Supplemental Indenture, dated as of November 15, 2012 (as so supplemented, herein called the “Indenture”), between the Co-Obligors and The Bank of New York Mellon, as Trustee (herein called the “Trustee”, which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto relating to the Notes reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Co-Obligors, the Trustee and the Holders of the Notes and of the terms upon which the Notes are, and are to be, authenticated and delivered.  This Note is one of the series designated on the face hereof, initially limited in aggregate principal amount to $200,000,000. Under a Board Resolution, Officer’s Certificate pursuant to Board Resolutions or a supplemental indenture, the Co-Obligors may from time to time, without the consent of the Holders of Notes, issue additional Notes (in any such case “Additional Notes”) having the same ranking and the same interest rate, maturity and other terms as the Notes. Any Additional Notes and the Initial Notes will constitute a single series under the Indenture and all references to the relevant Notes herein shall include the Additional Notes unless the context otherwise requires.

Optional Redemption.  The Notes are subject to redemption at the Co-Obligors’ option, at any time and from time to time, in whole or in part, at a Redemption Price equal to the sum of (i) the principal amount of the Notes being redeemed, (ii) unpaid interest accrued thereon to the redemption date and (iii) the Make-Whole Amount (as defined below), if any, with respect to such Notes. If the Notes are redeemed on or after September 1, 2022 (60 days prior to the maturity date of the Notes), the redemption price for the Notes will equal 100% of the principal amount of the Notes, plus unpaid accrued interest thereon to the redemption date.

For purposes of determining the optional redemption price, the following definitions are applicable:

“Make-Whole Amount” means, in connection with any optional redemption, the excess, if any, of (i) the aggregate present value as of the date of such redemption of each dollar of principal being redeemed and the amount of interest (exclusive of interest accrued to the date of redemption) that would have been payable in respect of each such dollar if such redemption had not been made, determined by discounting, on a semi-annual basis, such principal and interest at the Reinvestment Rate (determined on the third business day in The City of New York preceding the date such notice of redemption is given) from the respective dates on which such principal and interest would have been payable if such redemption had not been made, to the date of such redemption over (ii) the aggregate principal amount of the Notes being redeemed. The Co-Obligors shall be solely responsible for calculating the Make-Whole Amount.

“Reinvestment Rate” means 0.45% plus the arithmetic mean of the yields under the heading “Week Ending” published in the most recent Statistical Release under the caption “Treasury Constant Maturities” for the maturity (rounded to the nearest month) corresponding to the remaining life to maturity, as of the redemption date, of the principal being redeemed. If no maturity exactly corresponds to such maturity, yields for the two published maturities most closely corresponding to such maturity shall be calculated pursuant to the immediately preceding sentence and the Reinvestment Rate shall be

interpolated or extrapolated from such yields on a straight-line basis, rounding each of such relevant periods to the nearest month. For the purpose of calculating the Reinvestment Rate, the most recent Statistical Release published prior to the date of determination of the Make-Whole Amount shall be used.

“Statistical Release” means the statistical release designated “H.15 (519)” or any successor publication which is published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded United States government securities adjusted to constant maturities or, if such statistical release is not published at the time of any determination under the Indenture, then such other reasonably comparable index designated by the Co-Obligors.

Notice of any redemption will be mailed at least 30 days but not more than 60 days before the Redemption Date (unless a shorter period shall be satisfactory to the Trustee) to each registered Holder of the Notes to be redeemed. Unless the Co-Obligors default in payment of the redemption price, on and after the Redemption Date, interest will cease to accrue on the Notes or portions of the Notes called for redemption.  If fewer than all of the Notes are to be redeemed, the Outstanding Notes shall be redeemed on a pro rata basis.

Except as set forth above, the Notes will not be redeemable by the Co-Obligors prior to maturity and will not be entitled to the benefit of any sinking fund.

Defaults and Remedies.  If an Event of Default with respect to Notes shall occur and be continuing, the principal of the Notes may be declared due and payable in the manner and with the effect provided in the Indenture.

Amendment, Modification and Waiver.  The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the respective Co-Obligors and the rights of the Holders of the Notes of each series to be affected under the Indenture at any time by the applicable Co-Obligors and the Trustee with the consent of the Holders of a majority in aggregate principal amount of the Notes at the time Outstanding of each series to be affected.  The Indenture also contains provisions permitting the Holders of a majority in aggregate principal amount of the Notes of each series at the time Outstanding, on behalf of the Holders of all Notes of such series, to waive compliance by the Co-Obligors with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences.  Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note.

Denominations, Transfer and Exchange.  The Notes are issuable only in registered form without coupons in denominations of $2,000 and in integral multiples of $1,000 in excess thereof.  As provided in the Indenture and subject to certain limitations therein set forth, Notes are exchangeable for a like aggregate principal amount of Notes of like tenor of a different authorized denomination, as requested by the Holder surrendering the same.

As provided in the Indenture and subject to certain limitations therein set forth, the transfer of this Note is registerable in the Security Register, upon surrender of this Note for registration of transfer at the Registrar accompanied by a written request for transfer in form satisfactory to the Co-Obligors and the Registrar duly executed by, the Holder hereof or his attorney duly authorized in writing, and thereupon one or more new Notes and of like tenor, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

No service charge shall be made for any such registration of transfer or exchange, but the Co-Obligors may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

Persons Deemed Owners.  Prior to due presentment of this Note for registration of transfer, the Co-Obligors, the Trustee and any agent of the Co-Obligors or the Trustee may treat the Person in whose name this Note is registered as the owner hereof for all purposes, whether or not this Note be overdue, and neither the Co-Obligors, the Trustee nor any such agent shall be affected by notice to the contrary.

Miscellaneous.  The Indenture and this Note shall be governed by and construed in accordance with the laws of the State of New York, without regard to the conflicts of law rules of said State.

All terms used in this Note and not defined herein shall have the meanings assigned to them in the Indenture.
