4.000% Senior Notes due 2025

Capitalized terms used herein have the meanings assigned to them in the Indenture referred to below unless otherwise indicated.

(1) Interest. The Notes will bear interest from, and including, October 26, 2015, or from, and including, the most recent interest payment date to which interest has been paid or duly provided for, to, but excluding, the applicable interest payment date or Maturity Date of the Notes, as applicable, at a rate of 4.000% per annum, payable semi-annually in arrears on May 15 and November 15 of each year, commencing May 15, 2016. The Issuer will pay interest to the Person in whose name a Note is registered at the close of business on May 1 or November 1 next preceding the interest payment date. The Issuer will compute interest on the basis of a 360-day year consisting of twelve 30-day months. If any interest payment date or Maturity Date falls on a day that is not a Business Day, the required payment of principal, Make-Whole Premium (as defined below), if any, or interest will be made on the next succeeding Business Day as if made on the date on which such payment was due, and no interest will accrue on such payment for the period from and after such interest payment date or Maturity Date, as the case may be, to the date of such payment on the next succeeding Business Day.

(2) Place of Payment for Principal and Interest.  The principal of and interest on the Notes will be payable at the office or agency of the Issuer maintained for that purpose, pursuant to the Indenture, in the City of New York, which initially shall be the corporate trust office of the Trustee; provided, however, that at the option of the Issuer, such payment of principal, Make-Whole Premium, if any, or interest may be made by check mailed to the person entitled thereto as provided in the Indenture.

(3) Paying Agent and Security Registrar. Initially, U.S. Bank National Association, the Trustee under the Indenture, will act as Paying Agent and Security Registrar. The Issuer may change any Paying Agent or Security Registrar without notice to any Holder. The Issuer or any of its Subsidiaries may act in any such capacity.

(4) Sinking Funds. The Notes are not subject to repayment at the option of the Holder thereof. In addition, the Notes are not entitled to the benefit of, and are not subject to, any sinking fund.

(5) Indenture. The Issuer issued the Notes under an indenture, dated as of September 16, 2011 (the “Base Indenture”), as amended by the First Supplemental Indenture, dated as of June 26, 2012 (the “First Supplemental Indenture”), the Second Supplemental Indenture, dated as of December 17, 2013 (the “Second Supplemental Indenture”) and the Third Supplemental Indenture, dated as of October 26, 2015 (the “Third Supplemental Indenture” and, together with the Base Indenture, the First Supplemental Indenture and the Second Supplemental Indenture and as the Base Indenture, the First Supplemental Indenture, the Second Supplemental Indenture and the Third Supplemental Indenture may be further amended and supplemented from time to time, the “Indenture”), among the Issuer, the Guarantor named therein and the Trustee. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended (15 U.S. Code §§ 77aaa-77bbbb). The Notes are subject to all such terms, and Holders are referred to the Indenture and such Act for a statement of such terms. To the extent any provision of this Note conflicts with the express provisions of the Indenture, the provisions of the Indenture shall govern and be controlling. The Notes are unsecured obligations of the Issuer.

(i) 100% of the principal amount of the Notes then outstanding to be redeemed; and

(ii) the sum, as set forth in an Officers’ Certificate delivered to the Trustee, of the present values of the remaining scheduled payments of principal of, and interest on, the Notes to be redeemed (not including any portion of such payments of interest accrued to the Redemption Date), assuming such Notes matured on the Par Call Date, discounted to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the applicable Treasury Rate plus 30 basis points (the “Make-Whole Premium”);

plus any accrued and unpaid interest on the principal amount of the Notes being redeemed to, but not including, the Redemption Date.

(c)          If any Redemption Date falls on a day that is not a Business Day, the required payment of principal, Make-Whole Premium, if any, or interest on the Notes to be redeemed will be made on the next succeeding Business Day as if made on the date on which such payment was due, and no interest will accrue on such payment for the period from and after such Redemption Date, as the case may be, to the date of such payment on the next succeeding Business Day; provided, however, that with respect to a Redemption Date, if the next such succeeding Business Day falls on a day in the next succeeding calendar year with respect to a Redemption Date, the required payment of principal, Make-Whole Premium, if any, or interest on the Notes to be redeemed shall be made on the Business Day immediately preceding such Redemption Date on which payment was due.

(d)         If notice has been given in the manner provided in Section 1104 of the Indenture and funds for the redemption of the Note or any part thereof called for redemption will have been made available on the Redemption Date, the Notes to be redeemed, or such part thereof, will cease to accrue interest from and after the Redemption Date referred to in such notice and the only right of the Holder will be to receive payment of the Redemption Price.

(5) that on the Redemption Date the Redemption Price shall become due and payable upon each such Note or portion thereof, and that interest or original issue discount thereon, if any, shall cease to accrue on and after said date; and

(6) the place or places where such Notes are to be surrendered for payment of the Redemption Price.

If any Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in principal amount of the Notes then outstanding may declare the entire principal amount of the Notes to be due and payable. Subject to certain limitations, the Holders of a majority in principal amount of the Notes then outstanding may direct the Trustee in its exercise of any trust or power. Subject to certain exceptions, the Holders of a majority in aggregate principal amount of the Notes then outstanding by notice to the Trustee may on behalf of the Holders of all of the Notes waive any existing Default or Event of Default and its consequences under the Indenture except a continuing Default or Event of Default in the payment of principal of, premium, if any, or interest on the Notes.

No trustee, officer, employee or stockholder of CubeSmart or any of its Subsidiaries, as such, will have any liability for any obligations of CubeSmart or any of its Subsidiaries under the Notes or the Indenture based on, in respect of, or by reason of such obligations or their creation. Each Holder by accepting a Note waives and releases all such liability. The foregoing waiver and release are an integral part of the consideration for the issuance of the Notes.

(13) Authentication. No Note shall be entitled to any benefit under the Indenture or be valid or obligatory for any purpose unless there appears on such Note the certificate of authentication manually executed by the Trustee for such Note or on its behalf pursuant to Section 614 of the Indenture, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Note has been duly authenticated and delivered hereunder.

(14) CUSIP Numbers. The Issuer in issuing the Notes may use “CUSIP” numbers (if then generally in use) or other identifying numbers (“Identifying Numbers”) and, if so, the Trustee shall use such Identifying Numbers in notices of redemption as a convenience to Holders; provided that any such notice may state that no representation is made as to the correctness of such Identifying Numbers either as printed on the Notes or as contained in any notice of a redemption and that reliance may be placed only on the other identifying numbers printed on the Notes, and any such redemption shall not be affected by any defect in or omission of such numbers. The Issuer shall promptly notify the Trustee of any change in the Identifying Numbers.

The Issuer will furnish to any Holder upon written request and without charge a copy of the Indenture. Requests may be made to:
