#### FORWARD-LOOKING STATEMENTS
This prospectus and any accompanying prospectus supplement, together with other documents and information incorporated by reference into this prospectus and any accompanying prospectus supplement, contain certain forward-looking statements within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act. Forward-looking statements include statements concerning our plans, objectives, goals, strategies, future events, future revenues or performance, capital expenditures, financing needs, plans or intentions relating to acquisitions and other information that is not historical information. In some cases, forward-looking statements can be identified by terminology such as "believes," "expects," "estimates," "may," "will," "should," "anticipates," or "intends" or the negative of such terms or other comparable terminology, or by discussions of strategy. Such statements are based on assumptions and expectations that may not be realized and are inherently subject to risks, uncertainties and other factors, many of which cannot be predicted with accuracy and some of which might not even be anticipated. Although we believe the expectations reflected in these forward-looking statements are based on reasonable assumptions, future events and actual results, performance, transactions or achievements, financial and otherwise, may differ materially from the results, performance, transactions or achievements expressed or implied by the forward-looking statements contained in or contemplated by this prospectus or any prospectus supplement. As a result, you should not rely on or construe any forward-looking statements in this prospectus or any prospectus supplement or the documents and information incorporated by reference into this prospectus or any prospectus supplement, or which management or persons acting on their behalf may make orally or in writing from time to time, as predictions of future events or as guarantees of future performance. We caution you not to place undue reliance on forward-looking statements, which speak only as of the date of this prospectus or any prospectus supplement, the dates of the documents incorporated by reference herein or as of the dates otherwise indicated in such forward-looking statements, as applicable. All of our forward-looking statements, including those contained or incorporated by reference in this prospectus or any prospectus supplement are qualified in their entirety by this statement.

There are a number of risks and uncertainties that could cause our actual results to differ materially from the forward-looking statements contained in, contemplated by or incorporated by reference in this prospectus or any prospectus supplement. Any forward-looking statements should be considered in light of the risks and uncertainties referred to in Item 1A. "Risk Factors" in CubeSmart's and the Operating Partnership's Annual Report on Form 10-K for the year ended December 31, 2022 and in our periodic reports and other information that we subsequently file with the SEC. These risks include, but are not limited to the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • adverse changes in economic conditions in the real estate industry and in the markets in which we own and operate self-storage properties;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the effect of competition from existing and new self-storage properties and operators on our ability to maintain or raise occupancy and rental rates;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the failure to execute our business plan;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • adverse impacts from the COVID-19 pandemic, other pandemics, quarantines and stay at home orders, including the impact on our ability to operate our self-storage properties, the demand for self-storage, rental rates and fees and rent collection levels;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • reduced availability and increased costs of external sources of capital;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • increases in interest rates and operating costs;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • financing risks, including the risk of over-leverage and the corresponding risk of default on our mortgage and other debt and potential inability to refinance existing or future debt;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • counterparty non-performance related to the use of derivative financial instruments;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • risks related to our ability to maintain CubeSmart's qualification as a REIT for federal income tax purposes;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the failure of acquisitions and developments to close on expected terms, or at all, or to perform as expected;

[**TABLE OF CONTENTS**](#TOC)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • increases in taxes, fees and assessments from state and local jurisdictions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the failure of our joint venture partners to fulfill their obligations to us or their pursuit of actions that are inconsistent with our objectives;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • reductions in asset valuations and related impairment charges;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • cyber security breaches, cyber or ransomware attacks or a failure of our networks, systems or technology, which could adversely impact our business, customer and employee relationships or result in fraudulent payments;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • changes in real estate, zoning, use and occupancy laws or regulations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • risks related to or a consequence of natural disasters or acts of violence, pandemics, active shooters, terrorism, insurrection or war that affect the markets in which we operate;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • potential environmental and other liabilities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • governmental, administrative and executive orders and laws, which could adversely impact our business operations and customer and employee relationships;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • uninsured or uninsurable losses and the ability to obtain insurance coverage or recovery from insurance against risks and losses;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the ability to attract and retain talent in the current labor market;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • other factors affecting the real estate industry generally or the self-storage industry in particular; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • other risks identified in our Annual Report on Form 10-K for the year ended December 31, 2022 and, from time to time, in subsequent reports that we file with the SEC or in other documents that we publicly disseminate.

Given these uncertainties and the other risks identified elsewhere in this prospectus and any accompanying prospectus supplement, together with other documents and information incorporated by reference into this prospectus and any accompanying prospectus supplement, we caution readers not to place undue reliance on forward-looking statements. We undertake no obligation to publicly update or revise any forward-looking statements included or incorporated by reference in this prospectus or any prospectus supplement, whether as a result of new information, future events or otherwise except as may be required by securities laws. Because of the factors referred to above, the future events discussed in or incorporated by reference in this prospectus or any prospectus supplement may not occur and actual results, performance or achievement could differ materially from that anticipated or implied in the forward-looking statements.

#### CUBESMART AND THE OPERATING PARTNERSHIP
We are a self-administered and self-managed real estate company focused primarily on the ownership, operation, management, acquisition, and development of self-storage properties in the United States.

CubeSmart was formed in July 2004 as a Maryland REIT. CubeSmart owns its assets and conducts its business through the Operating Partnership, and its subsidiaries. CubeSmart controls the Operating Partnership as its sole general partner and, as of December 31, 2022, owned an approximately 99.4% interest in the Operating Partnership. The Operating Partnership was formed in July 2004 as a Delaware limited partnership and has been engaged in virtually all aspects of the self-storage business, including the ownership, operation, management, acquisition, and development of self-storage properties.

Our self-storage properties are designed to offer affordable and easily-accessible storage space for our residential and commercial customers. Our customers rent storage cubes for their exclusive use, typically on a month-to-month basis. Additionally, some of our stores offer outside storage areas for vehicles and boats. Our stores are designed to accommodate both residential and commercial customers, with features such as wide aisles and load-bearing capabilities for large truck access. All of our stores have a storage associate available to assist our customers during business hours and many of our owned stores have a manager who resides in an apartment at the store. Our customers can access their storage cubes during business hours, and some of our stores provide customers with 24-hour access through computer-controlled access systems. Our goal is to provide customers with the highest standard of physical attributes and service in the industry. To that end, many of our owned stores include climate-controlled cubes.

Our executive offices are located at 5 Old Lancaster Road, Malvern, PA 19355 and our telephone number is (610) 535-5000.

You should carefully consider the risk factors incorporated by reference to our most recent Annual Report on Form 10-K and the other information contained or incorporated by reference in this prospectus, as updated by our subsequent filings under the Exchange Act, and the risk factors and other information contained in the applicable prospectus supplement before acquiring any of such securities.

[**TABLE OF CONTENTS**](#TOC)

#### USE OF PROCEEDS
Unless otherwise indicated in the applicable prospectus supplement, CubeSmart will contribute or otherwise transfer the net proceeds of any sale of securities to the Operating Partnership in exchange for additional partnership interests in the Operating Partnership, the economic terms of which will be substantially identical to those of the securities sold. We will not receive any proceeds from the resale by any selling securityholders of common shares.

Unless otherwise indicated in the applicable prospectus supplement, the Operating Partnership will use those net proceeds and any net proceeds from any sale of its debt securities for general business purposes, including, without limitation, repayment of outstanding debt, acquisitions, developments, investments in joint ventures, capital expenditures, working capital and other general corporate purposes.

Both Maryland statutory law governing REITs formed under Maryland law, which we refer to as the "Maryland REIT Law", and CubeSmart's declaration of trust provide that none of its shareholders will be personally liable, by reason of status as a shareholder, for any of its obligations.

#### Common Shares
Each common share generally entitles the holder thereof to one vote per share on all matters upon which shareholders are entitled to vote and, except as provided with respect to any class or series of preferred shares that CubeSmart may issue, the holders of common shares will possess exclusive voting power on all matters as to which shareholders have voting rights. There is no cumulative voting in the election of trustees. CubeSmart's bylaws provide that a plurality of the votes cast at a meeting of shareholders duly called at which a quorum is present is sufficient to elect a trustee and that a majority of the votes cast at a meeting of shareholders duly called at which a quorum is present is sufficient to approve any other matter which may properly come before the meeting, unless a higher vote is required under CubeSmart's declaration of trust or bylaws or applicable statute. Generally, shareholders have the right to vote on: (i) the election of trustees; (ii) mergers or consolidations of CubeSmart and the sale by CubeSmart of all or substantially all of its assets; and (iii) certain amendments to CubeSmart's declaration of trust. Shareholders also have the right to propose amendments or modifications to CubeSmart's bylaws and to vote on such amendments and modifications. Under the Maryland REIT law, a Maryland REIT generally cannot amend its declaration of trust or merge with another entity without the affirmative vote of shareholders holding at least two-thirds of the shares entitled to vote on the matter unless a lesser percentage (but not less than a majority of all the votes entitled to be cast on the matter) is set forth in the REIT's declaration of trust. Under CubeSmart's declaration of trust, approval of such matters would require the affirmative vote of the majority of the shares entitled to vote on such matters. CubeSmart's board of trustees may amend the declaration of trust without shareholder approval to maintain CubeSmart's qualification as a REIT, under the Internal Revenue Code of 1986, as amended (the "Code"), or in any manner in which the charter of a Maryland corporation may be amended without shareholder approval.

All common shares offered by this prospectus will be duly authorized, fully paid and nonassessable. Subject to the preferences of any future class or series of preferred shares, holders of common shares are entitled to receive dividends and distributions, if any, when authorized by CubeSmart's board of trustees, and payable out of assets legally available for the payment of dividends or distributions. Holders of common shares are entitled to share ratably in CubeSmart's assets legally available for distribution to shareholders in the event of CubeSmart's liquidation, dissolution or winding up, after payment of or adequate provision for all of CubeSmart's known debts and liabilities, and subject to the preferential rights, if any, of the holders of any class or series of preferred shares that CubeSmart may issue.

Holders of common shares have no preference, conversion, exchange, sinking fund, redemption or appraisal rights and have no preemptive rights to subscribe for any of CubeSmart's securities. Subject to the

------

[**TABLE OF CONTENTS**](#TOC)

restrictions on transfer of shares contained in the declaration of trust and to the power of CubeSmart's board of trustees to create common shares with differing voting rights, all common shares have equal dividend, liquidation and other rights.

#### Preferred Shares
CubeSmart's board of trustees is authorized, without shareholder approval, to classify and designate the rights, preferences, privileges and restrictions of one or more classes or series of our authorized preferred shares. Prior to the issuance of a new class or series of preferred shares, CubeSmart would file with State Department of Assessments and Taxation of Maryland articles supplementary to set the preferences, conversion or other rights, voting powers, restrictions and limitations as to dividends and other distributions, qualifications and terms and conditions of redemption for such class or series. Any class or series of preferred shares that CubeSmart may issue that ranks senior to common shares as to dividends and distributions would limit CubeSmart's ability to pay dividends and distributions on common shares until full distributions have been paid with respect to such preferred shares.

We will describe the specific terms of a particular series of preferred shares in the prospectus supplement relating to that series, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the title of the series and the number of shares in the series;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the price at which the preferred shares will be offered;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the dividend rate or rates or method of calculating the rates, the dates on which the dividends will be payable, whether or not dividends will be cumulative or non-cumulative and, if cumulative, the dates from which dividends on the preferred shares being offered will cumulate;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the voting rights, if any, of the holders of preferred shares being offered;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the provisions for a sinking fund, if any, and the provisions for redemption, if applicable, of the preferred shares being offered;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the liquidation preference per share;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the terms and conditions, if applicable, upon which the preferred shares being offered will be convertible into CubeSmart's common shares, including the conversion price, or the manner of calculating the conversion price, and the conversion period;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the terms and conditions, if applicable, upon which the preferred shares being offered will be exchangeable for debt securities, including the exchange price, or the manner of calculating the exchange price, and the exchange period;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • any listing of the preferred shares being offered on any securities exchange;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • whether interests in the shares of the series will be represented by depositary shares;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • a discussion of any material U.S. federal income tax considerations applicable to the preferred shares being offered;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the relative ranking and preferences of the preferred shares being offered as to dividend rights and rights upon liquidation, dissolution or the winding up of CubeSmart's affairs;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • any limitations on the issuance of any class or series of preferred shares ranking senior or equal to the series of preferred shares being offered as to dividend rights and rights upon liquidation, dissolution or the winding up of CubeSmart's affairs;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • information with respect to book-entry procedures, if any; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • any additional rights, preferences, qualifications, limitations and restrictions of the series.

CubeSmart's board of trustees could authorize, without shareholder approval, the issuance of preferred shares with terms and conditions that could have the effect of discouraging a takeover or other transaction in which holders of some or a majority of shares might receive a premium for their shares over the then-prevailing market price of its shares. We currently do not expect that the board of trustees would require

------

[**TABLE OF CONTENTS**](#TOC)

shareholder approval prior to such a preferred issuance. In addition, any preferred shares that CubeSmart issues would rank senior to its common shares with respect to the payment of distributions, in which case CubeSmart could not pay any distributions on its common shares until full distributions have been paid with respect to such preferred shares.

#### Restrictions on Ownership and Transfer
In order for CubeSmart to maintain its qualification as a REIT under the Code, shares must be beneficially owned by 100 or more persons during at least 335 days of a taxable year of 12 months or during a proportionate part of a shorter taxable year. Also, no more than 50% of the value of CubeSmart's outstanding shares may be owned, directly, indirectly or through attribution, by five or fewer individuals (as defined in the Code to include certain entities).

Because CubeSmart's board of trustees believes that it is important for CubeSmart to continue to qualify as a REIT for U.S. federal income tax purposes, CubeSmart's declaration of trust, subject to certain exceptions, contains restrictions on percentage of shares of beneficial interest that a person may own. Under the declaration of trust:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • no person may own directly or indirectly, or be deemed to own through attribution, more than 9.8% in value or number of shares (whichever is more restrictive) of the issued and outstanding (a) common shares or (b) shares of any class or series of preferred shares;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • no person may beneficially or constructively own shares that would result in CubeSmart being "closely held" under Section 856(h) of the Code or otherwise cause us to fail to qualify as a REIT for U.S. federal income tax purposes; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • no person may transfer shares if such transfer would result in shares being owned by fewer than 100 persons.

CubeSmart's board of trustees may exempt a person that is not an individual from the 9.8% ownership limit if such person provides information and makes representations to the board of trustees that are satisfactory to the board of trustees, in its reasonable discretion, to establish that such person's ownership in excess of the 9.8% limit would not jeopardize CubeSmart's qualification as a REIT for U.S. federal income tax purposes.

Any person who acquires or attempts or intends to acquire beneficial or constructive ownership of shares that will or may violate any of the foregoing restrictions on transferability and ownership will be required to give us immediate notice and provide such other information to us as we may request in order to determine the effect of such transfer on CubeSmart's status as a REIT for U.S. federal income tax purposes. If any transfer of shares or any other event would otherwise result in any person violating the ownership limits described above, then CubeSmart's declaration of trust provides that (a) the transfer will be void and of no force or effect with respect to the prohibited transferee with respect to that number of shares that exceeds the ownership limits or that such number of shares will be automatically transferred to a charitable trust for the benefit of a charitable beneficiary and (b) the prohibited transferee would not acquire any right or interest in the shares. The foregoing restrictions on transferability and ownership would not apply if CubeSmart's board of trustees were to determine that it is no longer in CubeSmart's best interests to attempt to qualify, or to continue to qualify, as a REIT for U.S. federal income tax purposes.

All certificates evidencing shares bear a legend referring to the restrictions described above.

The declaration of trust expressly provides that the ownership limit and ownership restrictions on shares shall not preclude the settlement of any transaction entered into through the facilities of the New York Stock Exchange or any other national securities exchange or quotation system over which shares may be traded from time to time. The fact that the settlement of any transaction occurs shall not negate the effect of any other provision in the declaration of trust providing for ownership limit or ownership restrictions and any transferee in such a transaction shall be subject to all of such other provisions.

Every owner of more than 5% (or such lower percentage as required by the Code or the regulations promulgated thereunder) of all classes or series of shares, including common shares, is required to give written notice to us within 30 days after the end of each taxable year stating the name and address of such

------

[**TABLE OF CONTENTS**](#TOC)

owner, the number of shares of each class and series of shares that the owner beneficially owns and a description of the manner in which such shares are held. Each such owner shall provide to us such additional information as we may request in order to determine the effect, if any, of such beneficial ownership on CubeSmart's status as a REIT for U.S. federal income tax purposes and to ensure compliance with the ownership limitations. In addition, each shareholder is required, upon demand, to provide to us such information as we may request, in good faith, in order to determine CubeSmart's status as a REIT for U.S. federal income tax purposes and to comply with the requirements of any taxing authority or governmental authority or to determine such compliance.

The ownership limitations in the declaration of trust could discourage, delay or prevent a takeover, change of control or other transaction in which holders of some or a majority of CubeSmart's outstanding common shares might have received a premium for their shares over the then-prevailing market price of such shares.

#### Transfer Agent and Registrar
The transfer agent and registrar for our common shares is American Stock Transfer & Trust Co., LLC. The transfer agent and registrar for our preferred shares will be set forth in the applicable prospectus supplement.

#### Certain Provisions of Maryland Law and CubeSmart's Declaration of Trust and Bylaws
The following description of certain provisions of Maryland law and of CubeSmart's declaration of trust and bylaws is only a summary. For a complete description, we refer you to the applicable Maryland law and CubeSmart declaration of trust and bylaws.

 *Number of Trustees; Vacancies* 

CubeSmart's bylaws provide that at least a majority of our trustees will be "independent," with independence being defined in the manner established by CubeSmart's board of trustees and in a manner consistent with listing standards established by the NYSE.

 *Removal of Trustees* 

 *Business Combinations* 

CubeSmart's board of trustees has approved a resolution that exempts CubeSmart from the provisions of the Maryland business combination statute described below, but its board of trustees may opt to make these provisions applicable to CubeSmart in the future. Maryland law prohibits "business combinations" between CubeSmart and an interested shareholder (described below) or an affiliate of an interested shareholder for five years after the most recent date on which the interested shareholder becomes an interested shareholder. 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. Maryland law describes an interested shareholder as:

------

[**TABLE OF CONTENTS**](#TOC)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • any person who beneficially owns 10% or more of the voting power of CubeSmart's shares; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • an affiliate or associate of CubeSmart 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 CubeSmart's then-outstanding voting shares.

A person is not an interested shareholder if CubeSmart's board of trustees approves in advance the transaction by which the person otherwise would have become an interested shareholder. However, in approving a transaction, CubeSmart's board of trustees may provide that its approval is subject to compliance, at or after the time of approval, with any terms and conditions determined by CubeSmart's board of trustees.

After the five-year prohibition, any business combination between CubeSmart and an interested shareholder generally must be recommended by CubeSmart's board of trustees and approved by the affirmative vote of at least:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • 80% of the votes entitled to be cast by holders of CubeSmart's then outstanding shares of beneficial interest; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • two-thirds of the votes entitled to be cast by holders of CubeSmart's voting shares other than shares held by the interested shareholder with whom or with whose affiliate the business combination is to be effected or shares held by an affiliate or associate of the interested shareholder.

These super-majority vote requirements do not apply if CubeSmart's common shareholders receive a minimum price, as described under Maryland law, for their shares in the form of cash or other consideration in the same form as previously paid by the interested shareholder for its shares.

The statute permits various exemptions from its provisions, including business combinations that are approved by CubeSmart's board of trustees before the time that the interested shareholder becomes an interested shareholder.

 *Control Share Acquisitions* 

CubeSmart's bylaws contain a provision exempting any and all acquisitions of CubeSmart's shares from the provisions of the Maryland Control Share Acquisition Act. However, CubeSmart's board of trustees may opt to make these provisions applicable to an acquisition of CubeSmart's shares at any time by amending or repealing this provision in the future, and may do so on a retroactive basis. Maryland law provides that "control shares" of a Maryland REIT acquired in a "control share acquisition" have no voting rights unless approved by a vote of two-thirds of the votes entitled to be cast on the matter. Shares beneficially owned by the acquiring person in a control share acquisition or by CubeSmart's officers or employees who are CubeSmart's trustees are excluded from the shares entitled to vote in accordance with the immediately preceding sentence. "Control shares" are shares that, if aggregated with all other shares previously acquired by the acquiring person, or in respect of which the acquiring person is able to exercise or direct the exercise of voting power (except solely by virtue of a revocable proxy), would entitle the acquiring person to exercise or direct the exercise of the voting power in electing trustees within one of the following ranges of voting power:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • one-tenth or more but less than one-third;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • one-third or more but less than a majority; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • a majority or more of all voting power.

Control shares do not include shares the acquiring person is then entitled to vote as a result of having previously obtained shareholder approval. A "control share acquisition" means the acquisition of control shares, subject to certain exceptions.

A person who has made or proposes to make a control share acquisition may compel CubeSmart's board of trustees to call a special meeting of shareholders to be held within 50 days of demand to consider the voting rights of the shares. The right to compel the calling of a special meeting is subject to the satisfaction of certain conditions, including an undertaking to pay the expenses of the special meeting. If no request for a special meeting is made, we may present the question at any shareholders' meeting.

------

[**TABLE OF CONTENTS**](#TOC)

If voting rights are not approved at the shareholders' meeting or if the acquiring person does not deliver the statement required by Maryland law, then, subject to certain conditions and limitations, we may redeem any or all of the control shares, except those for which voting rights have previously been approved, for fair value. Fair value is determined without regard to the absence of voting rights for the control shares and as of the date of the last control share acquisition or of any meeting of shareholders at which the voting rights of the shares were considered and not approved. If voting rights for control shares are approved at a shareholders' meeting, the acquiror may then vote a majority of the shares entitled to vote, and all other shareholders may exercise appraisal rights. The fair value of the shares for purposes of these appraisal rights may not be less than the highest price per share paid by the acquiror in the control share acquisition. The control share acquisition statute does not apply to shares acquired in a merger, consolidation or share exchange if we are a party to the transaction, nor does it apply to acquisitions approved by or exempted by our declaration of trust or bylaws.

#### Possible Anti-Takeover Effect of Certain Provisions of Maryland Law and CubeSmart's Declaration of Trust and Bylaws
The business combination provisions of Maryland law (if CubeSmart's board of trustees opts to make them applicable to CubeSmart), the control share acquisition provisions of Maryland law (if the applicable provision in CubeSmart's bylaws is rescinded), the limitations on removal of trustees, the restrictions on the acquisition of CubeSmart's shares of beneficial interest, the power to issue additional common shares or preferred shares and the advance notice provisions for shareholder trustee nominations and other shareholder proposals of our bylaws could have the effect of delaying, deterring or preventing a transaction or a change in control that might involve a premium price for holders of the common shares or might otherwise be in their best interest. The "unsolicited takeovers" provisions of Maryland law permit CubeSmart's board of trustees, without shareholder approval and regardless of what is provided in our declaration of trust or bylaws, to implement takeover defenses that we may not yet have.

[**TABLE OF CONTENTS**](#TOC)

#### DESCRIPTION OF DEPOSITARY SHARES

#### General
CubeSmart may elect to have shares of preferred shares represented by depositary shares. The shares of any series of the preferred shares underlying the depositary shares will be deposited under a separate deposit agreement between CubeSmart and a bank or trust company that we select. The prospectus supplement relating to a series of depositary shares will set forth the name and address of this preferred shares depositary. Subject to the terms of the deposit agreement, each owner of a depositary share will be entitled, proportionately, to all the rights, preferences and privileges of the preferred shares represented by such depositary share, including dividend, voting, redemption, conversion, exchange and liquidation rights. As of the date of this prospectus, there are no depositary shares outstanding.

The depositary shares will be evidenced by depositary receipts issued pursuant to the deposit agreement, each of which will represent the applicable interest in a number of shares of a particular series of the preferred shares described in the applicable prospectus supplement.

A holder of depositary shares will be entitled to receive the shares of preferred shares, but only in whole shares of preferred shares, underlying those depositary shares. If the depositary receipts delivered by the holder evidence a number of depositary shares in excess of the whole number of shares of preferred shares to be withdrawn, the depositary will deliver to that holder at the same time a new depositary receipt for the excess number of depositary shares.

#### Dividends and Other Distributions
The preferred shares depositary will distribute all cash dividends or other cash distributions in respect of the series of preferred shares represented by the depositary shares to the record holders of depositary receipts in proportion, to the extent possible, to the number of depositary shares owned by those holders. The depositary, however, will distribute only the amount that can be distributed without attributing to any depositary share a fraction of one cent, and any undistributed balance will be added to and treated as part of the next sum received by the depositary for distribution to record holders of depositary receipts then outstanding.

If there is a distribution other than in cash in respect of the preferred shares, the preferred shares depositary will distribute property received by it to the record holders of depositary receipts in proportion, insofar as possible, to the number of depositary shares owned by those holders, unless the preferred shares depositary determines that it is not feasible to make such a distribution. In that case, the preferred shares depositary may, with our approval, adopt any method that it deems equitable and practicable to effect the distribution, including a public or private sale of the property and distribution of the net proceeds from the sale to the holders.

The amount distributed in any of the above cases will be reduced by any amount we or the preferred shares depositary are required to withhold on account of taxes.

#### Conversion and Exchange
If any series of preferred shares underlying the depositary shares is subject to provisions relating to its conversion or exchange as set forth in an applicable prospectus supplement, each record holder of depositary receipts will have the right or obligation to convert or exchange the depositary shares evidenced by the depositary receipts pursuant to those provisions.

#### Redemption of Depositary Shares
If any series of preferred shares underlying the depositary shares is subject to redemption, the depositary shares will be redeemed from the proceeds received by the preferred shares depositary resulting from the redemption, in whole or in part, of the preferred shares held by the preferred shares depositary. Whenever CubeSmart redeems a share of preferred shares held by the preferred shares depositary, the preferred shares depositary will redeem as of the same redemption date a proportionate number of depositary shares representing the shares of preferred shares that were redeemed. The redemption price per depositary share

------

[**TABLE OF CONTENTS**](#TOC)

will be equal to the aggregate redemption price payable with respect to the number of shares of preferred shares underlying the depositary shares. If fewer than all the depositary shares are to be redeemed, the depositary shares to be redeemed will be selected by lot or proportionately as CubeSmart may determine.

After the date fixed for redemption, the depositary shares called for redemption will no longer be deemed to be outstanding and all rights of the holders of the depositary shares will cease, except the right to receive the redemption price. Any funds that we deposit with the preferred shares depositary relating to depositary shares which are not redeemed by the holders of the depositary shares will be returned to us after a period of two years from the date the funds are deposited by CubeSmart.

#### Voting
Upon receipt of notice of any meeting at which the holders of any shares of preferred shares underlying the depositary shares are entitled to vote, the preferred shares depositary will mail the information contained in the notice to the record holders of the depositary receipts. Each record holder of the depositary receipts on the record date, which will be the same date as the record date for the preferred shares, may then instruct the preferred shares depositary as to the exercise of the voting rights pertaining to the number of shares of preferred shares underlying that holder's depositary shares. The preferred shares depositary will try to vote the number of shares of preferred shares underlying the depositary shares in accordance with the instructions, and we will agree to take all reasonable action which the preferred shares depositary deems necessary to enable the preferred shares depositary to do so. The preferred shares depositary will abstain from voting the preferred shares to the extent that it does not receive specific written instructions from holders of depositary receipts representing the preferred shares.

#### Record Date
Subject to the provisions of the deposit agreement, whenever

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • any cash dividend or other cash distribution becomes payable,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • any distribution other than cash is made,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • any rights, preferences or privileges are offered with respect to the preferred shares,

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the preferred shares depositary receives notice of any meeting at which holders of preferred shares are entitled to vote or of which holders of preferred shares are entitled to notice, or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the preferred shares depositary receives notice of the mandatory conversion of or any election by us to call for the redemption of any preferred shares, the preferred shares depositary will in each instance fix a record date, which will be the same as the record date for the preferred shares, for the determination of the holders of depositary receipts:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • who will be entitled to receive dividends, distributions, rights, preferences or privileges or the net proceeds of any sale, or who will be entitled to give instructions for the exercise of voting rights at any such meeting or to receive notice of the meeting or the redemption or conversion.

#### Withdrawal of Preferred Shares
Upon surrender of depositary receipts at the principal office of the preferred shares depositary, upon payment of any unpaid amount due the preferred shares depositary, and subject to the terms of the deposit agreement, the owner of the depositary shares evidenced by the depositary receipts is entitled to delivery of the number of whole shares of preferred shares and all money and other property, if any, represented by the depositary shares. Partial shares of preferred shares will not be issued. If the depositary receipts delivered by the holder evidence a number of depositary shares in excess of the number of depositary shares representing the number of whole shares of preferred shares to be withdrawn, the preferred shares depositary will deliver to the holder at the same time a new depositary receipt evidencing the excess number of depositary shares. Holders of preferred shares that are withdrawn will not be entitled to deposit the shares that have been withdrawn under the deposit agreement or to receive depositary receipts.

------

[**TABLE OF CONTENTS**](#TOC)

#### Amendment and Termination of the Deposit Agreement
CubeSmart and the preferred shares depositary may at any time agree to amend the form of depositary receipt and any provision of the deposit agreement. However, any amendment that materially and adversely alters the rights of holders of depositary shares will not be effective unless the amendment has been approved by the holders of at least a majority of the depositary shares then outstanding. The deposit agreement may be terminated by CubeSmart or by the preferred shares depositary only if all outstanding shares have been redeemed or if a final distribution in respect of the underlying preferred shares has been made to the holders of the depositary shares in connection with our liquidation, dissolution or winding up.

#### Charges of Preferred Shares Depositary
CubeSmart will pay all charges of the preferred shares depositary including charges in connection with the initial deposit of the preferred shares, the initial issuance of the depositary receipts, the distribution of information to the holders of depositary receipts with respect to matters on which preference shares is entitled to vote, withdrawals of the preferred shares by the holders of depositary receipts or redemption or conversion of the preferred shares, except for taxes (including transfer taxes, if any) and other governmental charges and any other charges expressly provided in the deposit agreement to be at the expense of holders of depositary receipts or persons depositing preferred shares.

#### Miscellaneous
Neither CubeSmart nor the preferred shares depositary will be liable if either of us is prevented or delayed by law or any circumstance beyond our control in performing any obligations under the deposit agreement. The obligations of the preferred shares depositary under the deposit agreement are limited to performing its duties under the agreement without negligence or bad faith. Our obligations under the deposit agreement are limited to performing our duties in good faith. Neither CubeSmart nor the preferred shares depositary is obligated to prosecute or defend any legal proceeding in respect of any depositary shares or preferred shares unless satisfactory indemnity is furnished. CubeSmart and the preferred shares depositary may rely on advice of or information from counsel, accountants or other persons that they believe to be competent and on documents that they believe to be genuine.

The preferred shares depositary may resign at any time or be removed by CubeSmart, effective upon the acceptance by its successor of its appointment. If CubeSmart has not appointed a successor preferred shares depositary and the successor depositary has not accepted its appointment within 60 days after the preferred shares depositary delivered a resignation notice to CubeSmart, the preferred shares depositary may terminate the deposit agreement. See "Amendment and Termination of the Deposit Agreement" above.

The description in the applicable prospectus supplement of any depositary shares CubeSmart offers will not necessarily be complete and will be qualified in its entirety by reference to the applicable deposit agreement, which will be filed with the SEC if CubeSmart offers s depositary shares. For more information on how you can obtain copies of any depositary share agreement if CubeSmart offers depositary shares, see "Where You Can Find More Information." CubeSmart urges you to read the applicable depositary share agreement and any applicable prospectus supplement in their entirety.

#### DESCRIPTION OF WARRANTS
CubeSmart may issue warrants for the purchase of common shares, preferred shares or depositary shares. CubeSmart may issue warrants independently or together with any offered securities. The warrants may be attached to or separate from those offered securities. CubeSmart will issue the warrants under one or more warrant agreements to be entered into between CubeSmart and a warrant agent to be named in the applicable prospectus supplement. The warrant agent will act solely as our agent in connection with the warrants and will not assume any obligation or relationship of agency or trust for or with any holders or beneficial owners of warrants.

The prospectus supplement relating to any warrants that CubeSmart may offer will contain the specific terms of the warrants. These terms may include the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the aggregate number of warrants;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • any provisions for adjustment of the number or amount of securities receivable upon exercise of the warrants or the exercise price of the warrants;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the price or prices at which the securities purchasable upon exercise of the warrants may be purchased;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • if applicable, the date on and after which the warrants and the securities purchasable upon exercise of the warrants will be separately transferable;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • a discussion of any material U.S. federal income tax considerations applicable to the exercise of the warrants;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • any other terms of the warrants, including terms, procedures and limitations relating to the exchange and exercise of the warrants.

#### Exercise of Warrants
Each warrant will entitle the holder of the warrant to purchase for cash the amount of CubeSmart's common shares, preferred shares and/or depositary shares, as the case may be, at the exercise price stated or determinable in the applicable prospectus supplement for the warrants. Warrants may be exercised at any time up to the close of business on the expiration date shown in the applicable prospectus supplement, unless otherwise specified in such prospectus supplement. After the close of business on the expiration date, unexercised warrants will become void. Warrants may be exercised as described in the applicable prospectus supplement. When the warrant holder makes the payment and properly completes and signs the warrant certificate at the corporate trust office of the warrant agent or any other office indicated in the prospectus supplement, CubeSmart will, as soon as possible, forward the common shares, preferred shares and/or depositary shares that the warrant holder has purchased, as the case may be. If the warrant holder exercises the warrant for less than all of the warrants represented by the warrant certificate, CubeSmart will issue a new warrant certificate for the remaining warrants.

The description in the applicable prospectus supplement of any warrants CubeSmart offers will not necessarily be complete and will be qualified in its entirety by reference to the applicable warrant agreement and warrant certificate, which will be filed with the SEC if CubeSmart offers warrants. For more information on how you can obtain copies of any warrant certificate or warrant agreement if we offer warrants, see "Where You Can Find More Information." We urge you to read the applicable warrant certificate, the applicable warrant agreement and any applicable prospectus supplement in their entirety.

#### DESCRIPTION OF THE DEBT SECURITIES
The following summary sets forth the general terms and provisions of the indenture under which the debt securities will be issued by the Operating Partnership. The debt securities will be issued by the Operating Partnership under an indenture, as amended or supplemented from time to time, among the Operating Partnership, CubeSmart, as guarantor, and U.S. Bank National Association, as trustee, or such other trustee selected by the Operating Partnership.

The debt securities may be issued from time to time in one or more series. The particular terms and provisions of the debt securities with respect to a specific offering of debt securities will be set forth in the applicable prospectus supplement. This summary of general terms and provisions of the indenture and the debt securities does not purport to be complete and is subject to, and is qualified in its entirety by reference to, all provisions of the indenture and those debt securities.

The indenture is filed as an exhibit to the registration statement of which this prospectus is a part and will be available for inspection at the corporate trust office of the trustee or as described under "Where You Can Find More Information." The indenture will be qualified under, subject to, and governed by, the Trust Indenture Act of 1939, as amended, or the Trust Indenture Act.

All section references appearing herein are to sections of the indenture, and capitalized terms used but not defined herein will have the respective meanings set forth in the indenture.

#### General
The debt securities will be direct, unsecured obligations of the Operating Partnership. Except for any series of debt securities which is expressly subordinated to other indebtedness of the Operating Partnership, the debt securities will rank equally with all other unsecured and unsubordinated indebtedness of the Operating Partnership. Under the indenture, the debt securities may be issued without limit as to aggregate principal amount, in one or more series, as established from time to time pursuant to authority granted by a resolution of the board of trustees of CubeSmart as sole general partner of the Operating Partnership or as established in one or more supplemental indentures to the indenture. All of the debt securities of any one series need not be issued at the same time and, unless otherwise provided, a series may be reopened, without the consent of the holders of the debt securities of that series, for issuances of additional debt securities of that series. All debt securities of a particular series shall be substantially identical except as to denomination, date of issuance, issue price and the date from which interest, if any, shall accrue.

All of the debt securities will be fully and unconditionally guaranteed as to payment of principal and premium, if any, and interest by CubeSmart. The indenture allows certain of our subsidiaries from time to time to become guarantors of specific series of the debt securities.

The indenture provides that there may be more than one trustee for any one or more series of debt securities. Any trustee under the indenture may resign or be removed with respect to one or more series of debt securities, and a successor trustee may be appointed to act with respect to that series. Except as otherwise indicated in this prospectus or the applicable prospectus supplement, any action to be taken by the trustee may be taken by each such trustee with respect to, and only with respect to, the one or more series of debt securities for which it is trustee under the indenture.

#### Terms
The applicable prospectus supplement relating to the series of debt securities being offered will describe the specific terms and provisions of those debt securities, including the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the title of the debt securities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • any limit on the aggregate principal amount of the debt securities and whether any additional securities of such series may be issued without consent of the holders;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the date or dates, or the manner of determining the date or dates, on which the principal of the debt securities will be payable;

------

[**TABLE OF CONTENTS**](#TOC)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the extent and manner, if any, to which payments on the debt securities may be subordinated to other indebtedness of the Operating Partnership;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • whether the debt securities are entitled to the benefits of the guarantee of any subsidiary guarantor, and whether any such guarantee is made on a senior or subordinated basis and, if applicable, a description of the subordination terms of any such guarantee, and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • any other terms of the debt securities not inconsistent with the provisions of the indenture.

The debt securities may provide for less than the entire principal amount of those debt securities to be payable upon declaration of acceleration of the maturity thereof or original issue discount securities. The applicable prospectus supplement will describe special U.S. federal income tax, accounting and other considerations applicable to the original issue discount securities.

The indenture does not contain any provisions that would limit the ability of the Operating Partnership to incur indebtedness or that would afford holders of debt securities protection in the event of a highly leveraged or similar transaction involving the Operating Partnership. However, restrictions on ownership and transfers of CubeSmart's common shares and preferred shares, designed to preserve CubeSmart's status as a REIT for U.S. federal income tax purposes, may prevent or hinder a change of control. Reference is made to the applicable prospectus supplement for information with respect to any deletions from, modifications of or additions to the events of default or covenants of the Operating Partnership that are described below, including any addition of a covenant or other provision providing event risk or similar protection.

#### Guarantee
CubeSmart will, under the indenture, fully and unconditionally guarantee the due and punctual payment of principal of and premium, if any, and interest on all debt securities issued by the Operating Partnership, and the due and punctual payment of any sinking fund payments on those debt securities, when and as the same will become due and payable, whether at a maturity date, by declaration of acceleration, call for redemption or otherwise.

From time to time, subsidiaries of the Operating Partnership may join as guarantors under the indenture. Such subsidiaries' guarantees will be limited to the series of debt securities for which they execute notations of guarantee in accordance with the terms of the indenture, and may be released in connection with:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the sale, by the Operating Partnership, of the equity interests that it holds in the subsidiary guarantor; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the occurrence of certain conditions described in the supplemental indenture or related documents adopting the series of debt securities which are the subject of the subsidiary's guarantee.

The obligations of each guarantor, other than CubeSmart, under its guarantee will be limited as necessary to prevent that guarantee from constituting a fraudulent conveyance or fraudulent transfer under applicable law.

#### Denominations
Unless otherwise specified in the applicable prospectus supplement, the debt securities of any series shall be issuable only in registered form without coupons and, other than securities in global form (which may be of any denomination), will be issuable in denominations of $2,000 and integral multiples of $1,000 in excess thereof.

#### Payments
Unless otherwise specified in the applicable prospectus supplement, the principal of and premium, if any, and interest on any series of debt securities will be payable at the corporate trust office of the trustee. However, at the option of the Operating Partnership, payment of interest may be made by check mailed to the address of the person entitled thereto as it appears in the security register or by wire transfer of funds to that person at a bank account maintained within the United States.

------

[**TABLE OF CONTENTS**](#TOC)

All amounts paid by the Operating Partnership to a paying agent or a trustee for the payment of the principal of or premium, if any, or interest on any debt security which remains unclaimed at the end of two years after the principal, premium or interest has become due and payable will be repaid to the Operating Partnership, and the holder of the debt security thereafter may look only to the Operating Partnership for payment of these amounts.

Any interest not punctually paid or duly provided for on any interest payment date with respect to a debt security will forthwith cease to be payable to the holder on the applicable regular record date and may either be paid to the person in whose name that debt security is registered at the close of business on a special record date for the payment of that defaulted interest to be fixed by the trustee or may be paid at any time in any other lawful manner, all in accordance with the indenture. Notice of any special record date will be given to the holder of that debt security not less than 10 days prior to the special record date.

#### Registration and Transfer
Subject to certain limitations imposed upon debt securities issued in book-entry form, the debt securities of any series will be exchangeable for other debt securities of the same series, of a like aggregate principal amount and tenor, of different authorized denominations upon surrender of such debt securities at the corporate trust office of the trustee. In addition, subject to certain limitations imposed upon debt securities issued in book-entry form, the debt securities of any series may be surrendered for registration of transfer at the corporate trust office of the trustee.

Every debt security surrendered for registration of transfer or exchange will be duly endorsed or accompanied by a written instrument of transfer. No service charge will be made for any registration of transfer or exchange of any debt securities, but the Operating Partnership may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

If the applicable prospectus supplement refers to any transfer agent (in addition to the trustee) initially designated by the Operating Partnership and the guarantors with respect to any series of debt securities, the Operating Partnership may at any time rescind the designation of that transfer agent or approve a change in the location through which that transfer agent acts, except that the Operating Partnership and the guarantors will be required to maintain a transfer agent in each place of payment for that series. The Operating Partnership and the guarantors may at any time designate additional transfer agents with respect to any series of debt securities.

Neither the Operating Partnership nor the trustee will be required to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • issue, register the transfer of or exchange debt securities of any series during a period beginning at the opening of business 15 days before any selection of debt securities of that series to be redeemed and ending at the close of business of the day of mailing of the relevant notice of redemption; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • register the transfer of or exchange any debt security, or portion thereof, called for redemption, except the unredeemed portion of any debt security being redeemed in part.

#### Merger, Consolidation and Sale
Unless otherwise provided in the applicable prospectus supplement, the Operating Partnership may consolidate with, or sell, lease or convey all or substantially all of its assets to, or merge with or into, any other entity, provided that the following conditions are satisfied or fulfilled:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • either the Operating Partnership is the continuing entity, or the successor (if other than the Operating Partnership) formed by or resulting from any such consolidation or merger or which has received the transfer of those assets is organized under the laws of the United States of America and expressly assumes the due and punctual payment of the principal of and premium, if any, and interest on all of the debt securities and the performance and observance of all of the covenants and conditions contained in the indenture;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • immediately after giving effect to the transaction, no event of default under the indenture, and no event which, after notice or the lapse of time, or both, would become an event of default, has occurred and is continuing; and

[**TABLE OF CONTENTS**](#TOC)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • an officer's certificate of CubeSmart as general partner of the Operating Partnership and a legal opinion covering compliance with these conditions is delivered to the trustee.

Unless otherwise provided in the applicable prospectus supplement, CubeSmart may consolidate with, or sell, lease or convey all or substantially all its assets to, or merge with or into, any other entity, provided that substantially the same conditions as above are satisfied or fulfilled.

#### Covenants
We will set forth in the applicable prospectus supplement any financial covenants applicable to any issue of debt securities.

 *Provision of Financial Information* 

Unless otherwise provided in the applicable prospectus supplement, so long as any debt securities are outstanding, CubeSmart and the Operating Partnership will furnish to the trustee such information, documents and other reports as may be required by the Trust Indenture Act, including filing with the trustee within 15 days information, documents or reports required to be filed by the Issuer with the SEC.

 *Waiver of Certain Covenants* 

The Operating Partnership and the guarantors may choose not to comply with any term, provision or condition of certain covenants if at any time the holders of at least a majority in principal amount of all the outstanding debt securities, by act of those holders, either waive compliance in that instance or generally waive compliance with that covenant. Except to the extent so expressly waived, and until any waiver becomes effective, the Operating Partnership's and the guarantors' obligations and the duties of the trustee in respect of any such term, provision or condition will remain in full force and effect.

 *Existence* 

Unless otherwise provided in the applicable prospectus supplement, except as permitted under "Merger, Consolidation or Sale," each of the Operating Partnership and the guarantors will do or cause to be done all things necessary to preserve and keep in full force and effect its existence, rights (declaration and statutory) and franchises; provided, however, that neither the Operating Partnership nor any guarantor will be required to preserve any right or franchise if the board of directors of the Operating Partnership, or the board of trustees or analogous body of any subsidiary guarantor, determines that the preservation thereof is no longer necessary or desirable in the conduct of its business and that the loss of that right or franchise is not disadvantageous in any material respect to the holders of the debt securities.

 *Maintenance of Properties* 

Unless otherwise provided in the applicable prospectus supplement, each of the Operating Partnership and the guarantors will cause all of its material properties used or useful in the conduct of its business or the business of any of its Subsidiaries to be maintained and kept in good condition, repair and working order, all as in the judgment of the Operating Partnership or the applicable guarantor may be necessary so that the business carried on in connection with those properties may be properly and advantageously conducted at all times; provided, however, that, subject to the covenant described under "Merger, Consolidation and Sale" above, neither the Operating Partnership nor any guarantor nor any of their respective Subsidiaries will be prevented from selling or otherwise disposing of their properties at any time.

 *Payment of Taxes and Other Claims* 

Unless otherwise provided in the applicable prospectus supplement, each of the Operating Partnership and the guarantors will pay or discharge or cause to be paid or discharged, before becoming delinquent:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • all taxes, assessments and governmental charges levied or imposed upon it or any of its Subsidiaries or upon its income, profits or property or that of any of its Subsidiaries; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • all lawful claims for labor, materials and supplies which, if unpaid, might by law become a lien upon its property or the property of any of its Subsidiaries;

------

[**TABLE OF CONTENTS**](#TOC)

*provided, however*, that neither the Operating Partnership nor any guarantor will be required to pay or discharge or cause to be paid or discharged any tax, assessment, charge or claim whose amount or applicability is being contested in good faith.

 *Payment of Additional Amounts* 

Unless otherwise provided in the applicable prospectus supplement, each of the Operating Partnership and the guarantors will pay to any holder of debt securities that is a United States Alien such additional amounts as may be required such that every net payment on the debt securities held by such holder, after deduction or withholding on account of any present or future U.S. tax (other than taxes unrelated to the holder's ownership of the debt securities and certain other taxes), is not less than the amount provided in such debt securities as then due and payable.

 *Additional Covenants* 

The applicable prospectus supplement relating to the series of debt securities being offered will describe any additional covenants specific to that series.

#### Events of Default, Notice and Waiver
Unless otherwise provided in the applicable prospectus supplement, the indenture provides that the following events will be "events of default" with respect to any series of debt securities issued under the indenture:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (1)

default for 30 days in the payment of any interest on any debt security of that series;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (2)

default in the payment of any principal of or premium, if any, on any debt security of that series when due;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (3)

default in making any sinking fund payment as required for any debt security of that series;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (4)

default in the performance of any other covenant or warranty of the Operating Partnership and/or any of the guarantors contained in the indenture with respect to any debt security of that series, which continues for 60 days after written notice as provided in the indenture;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (5)

default in the payment of an aggregate principal amount exceeding $25,000,000 of any evidence of indebtedness of the Operating Partnership and/or any of the guarantors or any mortgage, indenture or other instrument under which that indebtedness is issued or by which that indebtedness is secured, such default having continued after the expiration of any applicable grace period or having resulted in the acceleration of the maturity of that indebtedness, but only if that indebtedness is not discharged or such acceleration is not rescinded or annulled within a period of 10 days after the Operating Partnership's receipt of written notice executed by holders of at least 25% in principal amount of the outstanding debt securities of that series;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (6)

certain events of bankruptcy, insolvency or reorganization, or court appointment of a receiver, liquidator or trustee of the Operating Partnership, CubeSmart, or any of their respective properties;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (7)

except as otherwise permitted in the indenture, any guarantee of the debt securities of any series is held in any judicial proceeding to be unenforceable or invalid or shall cease for any reason to be in full force and effect, or CubeSmart or any subsidiary guarantor shall deny or disaffirm its obligations under its guarantee with respect to the debt securities of the applicable series; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (8)

any other event of default provided with respect to a particular series of debt securities.

Unless otherwise provided in the applicable prospectus supplement, if an event of default (other than as described in clause (6) above) with respect to debt securities of any series at the time outstanding occurs and is continuing, then in each case the trustee or the holders of not less than 25% in principal amount of the outstanding debt securities of that series may declare the principal (or, if the debt securities of that series are original issue discount securities or indexed securities, that portion of the principal amount as may be specified in the terms thereof) of and premium, if any, and accrued and unpaid interest on all of the debt

------

[**TABLE OF CONTENTS**](#TOC)

securities of that series to be due and payable immediately by written notice thereof to the Operating Partnership and CubeSmart (and to the trustee if given by the holders). If an event of default described in clause (6) above occurs and is continuing, the principal (or such portion thereof) of and premium, if any, and accrued and unpaid interest on all of the debt securities of that series will become and be immediately due and payable without any declaration or other act on the part of the trustee or any holders. However, at any time after any acceleration with respect to debt securities of that series, but before a judgment or decree for payment of the amounts due has been obtained by the trustee, the holders of not less than a majority in principal amount of outstanding debt securities of that series may rescind and annul that acceleration and its consequences if (1) the Operating Partnership or any guarantor has paid or deposited with the trustee all required payments of the principal of and premium, if any, and interest on the debt securities of that series (without giving effect to the acceleration) plus certain fees, expenses, disbursements and, premium, if any, advances of the trustee and (2) all events of default, other than the nonpayment of accelerated principal, premium, if any, or interest with respect to debt securities of that series, have been cured or waived as provided in the indenture. The indenture also provides that the holders of not less than a majority in principal amount of the outstanding debt securities of any series may waive any past default with respect to that series and its consequences, except a default (A) in the payment of the principal of or premium, if any, or interest on any debt security of that series or (B) in respect of a covenant or provision contained in the indenture that cannot be modified or amended without the consent of the holder of each outstanding debt security affected thereby.

The trustee will be required to give notice to the holders of debt securities within 90 days of a default under the indenture unless such default has been cured or waived; provided, however, that the trustee may withhold notice to the holders of any series of debt securities of any default with respect to that series (except a default in the payment of the principal of or premium, if any, or interest on any debt securities of that series or in the payment of any sinking fund installment in respect of any debt securities of that series) if the responsible officers of the trustee consider withholding of notice to be in the interest of the holders.

The indenture provides that no holders of debt securities of any series may institute any judicial or other proceedings with respect to the indenture or for any remedy thereunder, except in the case of failure of the trustee, for 60 days, to act after it has received a written request to institute proceedings in respect of an event of default from the holders of not less than 25% in principal amount of the outstanding debt securities of that series, as well as an offer of reasonable security or indemnity. This provision will not prevent, however, any holder of debt securities from instituting suit for the enforcement of payment of the principal of and premium, if any, and interest on the debt securities at the respective due date or dates for payment.

Subject to provisions in the indenture relating to its duties in case of default, the trustee is under no obligation to exercise any of its rights or powers under the indenture at the request or direction of any holders of debt securities of any series then outstanding under the indenture, unless the holders offer to the trustee reasonable security or indemnity. The holders of not less than a majority in principal amount of the outstanding debt securities of any series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee, or of exercising any trust or power conferred upon the trustee for that series. However, the trustee may refuse to follow any direction which is in conflict with any law or the indenture, which may involve the trustee in personal liability or which may be unduly prejudicial to the holders of debt securities of that series not joining in the proceeding.

Within 120 days after the end of each fiscal year, the Operating Partnership and CubeSmart must deliver to the trustee a certificate, signed by one of several specified officers of the general partner of the Operating Partnership and of CubeSmart, stating whether or not such officers have knowledge of any default under the indenture and, if so, specifying each such default and the nature and status thereof.

#### Modification of the Indenture
Modifications and amendments of provisions of the indenture applicable to any series may be made only with consent of the holders of more than 50% in principal amount of all outstanding debt securities which are affected by the modification or amendment; provided, however, that no such modification or amendment may, without the consent of the holder of each debt security affected thereby:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • change the stated maturity of the principal of, or any installment of interest or premium, if any, on, that debt security;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • reduce the principal amount of, or the rate or amount of interest on, or any premium payable on redemption of, that debt security, or reduce the amount of principal of an original issue discount security that would be due and payable upon declaration of acceleration of the maturity thereof or would be provable in bankruptcy, or adversely affect any right of repayment of the holder of that debt security;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • change the place of payment, or the coin or currency, for payment of principal of, premium, if any, or interest on that debt security;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • impair the right to institute suit for the enforcement of any payment on or with respect to that debt security on or after the stated maturity thereof;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • reduce the percentage of outstanding debt securities of any series necessary to modify or amend the indenture, to waive compliance with certain provisions thereof or specified defaults and consequences thereunder or to reduce the quorum or voting requirements set forth in the indenture;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • modify or affect in any manner adverse to the holders the terms and conditions of the obligations of any of the guarantors in respect of the due and punctual payments of principal of (or premium, if any) or interest, if any, on or any sinking fund requirements or additional amounts under the guarantees applicable to that debt security; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • modify any of the foregoing provisions or any of the provisions relating to the waiver of certain past defaults or certain covenants, except to increase the required percentage to effect that action or to provide that certain other provisions may not be modified or waived without the consent of the holder of that debt security.

Modifications and amendments of the indenture may be made by the Operating Partnership, the guarantors and the trustee without the consent of any holder of debt securities for any of the following purposes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • to evidence the succession of another person to the Operating Partnership as obligor, or to any of the guarantors under the indenture;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • to add to the covenants of the Operating Partnership or any of the guarantors for the benefit of the holders of all or any series of debt securities or to surrender any right or power conferred upon the Operating Partnership or any of the guarantors in the indenture;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • to add events of default for the benefit of the holders of all or any series of debt securities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • to pledge property to the trustee to secure, or add additional guarantees with respect to, the debt securities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • to change or eliminate any provisions of the indenture, provided that the change or elimination will become effective only when there are no outstanding debt securities of any series created prior thereto which are entitled to the benefit of such provision;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • to provide for the acceptance of appointment by a successor trustee or facilitate the administration of the trust under the indenture by more than one trustee;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • to establish the form or terms of debt securities of any series;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • to supplement any of the provisions of the indenture to the extent necessary to permit or facilitate defeasance and discharge of any series of such debt securities, provided that such action will not adversely affect the interests of the holders of the debt securities of any series in any material respect;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • to supplement any of the provisions of the indenture to the extent necessary to permit or facilitate a merger or consolidation of the Operating Partnership or any Guarantor, provided that such action will not adversely affect the interests of the holders of the debt securities of any series in any material respect;

[**TABLE OF CONTENTS**](#TOC)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • to add to or change or eliminate any provisions of the indenture to the extent necessary or desirable in accordance with any amendments to the Trust Indenture Act or to maintain the qualification of the indenture under the Trust Indenture Act;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • to cure any ambiguity, defect or inconsistency in the indenture or to make any other provision with respect to matters or questions arising under the indenture, provided that such action will not adversely affect the interests of holders of debt securities of any series in any material respect;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • to provide for the issuance of any additional debt securities of a series with terms substantially identical to the issued debt securities of that series (which additional debt securities will be treated, together with the already issued debt securities of that series, as a single series of debt securities); or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • to reflect the release of any guarantor (other than CubeSmart) from the indenture.

The indenture provides that, in determining whether the holders of the requisite principal amount of outstanding debt securities of a series have given any request, demand, authorization, direction, notice, consent or waiver thereunder or whether a quorum is present at a meeting of holders of debt securities:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (1)

debt securities owned by the Operating Partnership, any of the guarantors or any other obligor upon the debt securities or any affiliate of the Operating Partnership, any of the guarantors or of that other obligor will be disregarded;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (2)

the principal amount of an original issue discount security that is deemed to be outstanding will be the amount of the principal thereof (or the U.S. dollar equivalent thereof on the date of original issuance, in the case of debt securities denominated in one or more foreign currencies) that would be due and payable as of the date of determination upon declaration of acceleration of the maturity of that debt security;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (3)

the principal amount of a debt security denominated in a foreign currency that is deemed outstanding will be the U.S. dollar equivalent, determined on the issue date for that debt security, of the principal amount (or, in the case of an original issue discount security, the U.S. dollar equivalent on the issue date of that debt security of the amount determined as provided in clause (2) above); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (4)

debt securities that have been cancelled or delivered to the trustee for cancellation, or for which payment has been made or the redemption amount has been deposited with the trustee as provided in the indenture, will be disregarded.

The indenture contains provisions for convening meetings of the holders of debt securities of a series. A meeting may be called at any time by the trustee, and also, upon request, by the Operating Partnership or the holders of at least 25% in principal amount of the outstanding debt securities of that series, in each case upon notice given as provided in the indenture. Except for any consent that must be given by the holder of each debt security affected by certain modifications and amendments of the indenture, any resolution presented at a meeting or adjourned meeting duly reconvened at which a quorum is present may be adopted by the affirmative vote of the holders of a majority in principal amount of the outstanding debt securities of that series; provided, however, that, except as referred to above, any resolution with respect to any request, demand, authorization, direction, notice, consent, waiver or other action that may be made, given or taken by the holders of a specified percentage, which is less than a majority, in principal amount of the outstanding debt securities of a series may be adopted at a meeting or adjourned meeting duly reconvened at which a quorum is present by the affirmative vote of the holders of the debt securities of that series. Any resolution passed or decision taken at any meeting of holders of debt securities of any series duly held in accordance with the indenture will be binding on all holders of debt securities of that series. The quorum at any meeting called to adopt a resolution, and at any reconvened meeting, will be persons holding or representing a majority in principal amount of the outstanding debt securities of a series; provided, however, that if any action is to be taken at such meeting with respect to a consent or waiver which may be given by the holders of not less than a specified percentage in principal amount of the outstanding debt securities of a series, the persons holding or representing such specified percentage in principal amount of the outstanding debt securities of such series will constitute a quorum.

------

[**TABLE OF CONTENTS**](#TOC)

Notwithstanding the foregoing provisions, if any action is to be taken at a meeting of holders of debt securities of any series with respect to any request, demand, authorization, direction, notice, consent, waiver or other action that the indenture expressly provides may be made, given or taken by the holders of a specified percentage in principal amount of all outstanding debt securities affected thereby, or of the holders of that series and one or more additional series:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • there will be no minimum quorum requirement for the meeting; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the principal amount of the outstanding debt securities of such series that vote in favor of the request, demand, authorization, direction, notice, consent, waiver or other action will be taken into account in determining whether such request, demand, authorization, direction, notice, consent, waiver or other action has been made, given or taken under the indenture.

#### Discharge; Legal Defeasance and Covenant Defeasance
Unless otherwise provided in the applicable prospectus supplement, the Operating Partnership and the guarantors may discharge certain obligations to holders of any series of debt securities that have not already been delivered to the trustee for cancellation and that either have become due and payable or will become due and payable within one year (or are scheduled for redemption within one year) by irrevocably depositing with the trustee, in trust, funds in such currency or currencies, currency unit or units or composite currency or currencies in which such debt securities are payable in an amount sufficient to pay the entire indebtedness on such debt securities in respect of principal and premium, if any, and interest to the date of such deposit (if such debt securities have become due and payable) or to the stated maturity or redemption date, as the case may be.

In addition, the indenture provides that, unless otherwise provided in the applicable prospectus supplement, the Operating Partnership may elect either:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • to defease and discharge itself and the guarantors from any and all obligations with respect to those debt securities (except for the obligation to pay additional amounts, if any, upon the occurrence of certain events of tax, assessment or governmental charge with respect to payments on such debt securities and the obligations to register the transfer or exchange of such debt securities, to replace temporary or mutilated, destroyed, lost or stolen debt securities, to maintain an office or agency in respect of such debt securities and to hold moneys for payment in trust), or legal defeasance; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • to release itself and the guarantors from their obligations with respect to those debt securities under "Covenants" or their obligations with respect to any other covenant, and any omission to comply with such obligations will not constitute a default or an event of default with respect to those debt securities, or covenant defeasance;

in either case upon the irrevocable deposit by the Operating Partnership or the guarantors with the trustee, in trust, of any amount, in such currency or currencies, currency unit or units or composite currency or currencies in which those debt securities are payable at stated maturity, or Government Obligations, or both, applicable to those debt securities which through the scheduled payment of principal and interest in accordance with their terms will provide money in an amount sufficient, based on a certification by officers of the Operating Partnership, to pay the principal of and premium, if any, and interest on such debt securities, and any mandatory sinking fund or analogous payments thereon, on the scheduled due dates.

This trust may only be established if, among other conditions, the Operating Partnership has delivered to the trustee an opinion of counsel to the effect that the beneficial owners of the debt securities will not recognize income, gain or loss for U.S. federal income tax purposes as a result of legal defeasance or covenant defeasance, as the case may be, and will be subject to U.S. federal income tax on the same amounts, in the same manner and at the same times as would have been the case if legal defeasance or covenant defeasance, as the case may be, had not occurred, and the opinion of counsel, in the case of legal defeasance, must refer to and be based upon a ruling of the Internal Revenue Service or a change in applicable U.S. federal income tax law occurring after the date of the indenture.

In the event the Operating Partnership effects covenant defeasance with respect to the debt securities of any series and those debt securities are declared due and payable because of the occurrence of any event of default other than an event of default described in clause (4) under "Events of Default, Notice and Waiver"

------

[**TABLE OF CONTENTS**](#TOC)

with respect to the covenants described under "Covenants" (which would no longer be applicable to those debt securities) or described in clause (7) under "Events of Default, Notice and Waiver" with respect to any other covenant as to which there has been covenant defeasance, the amount in the currency, currency unit or composite currency in which those debt securities are payable, and Government Obligations on deposit with the trustee, will be sufficient to pay amounts due on those debt securities at the time of their stated maturity but may not be sufficient to pay amounts due on those debt securities at the time of the acceleration resulting from such event of default. However, the Operating Partnership and the guarantors would remain liable to make payment of those amounts due at the time of acceleration.

The applicable prospectus supplement may further describe the provisions, if any, permitting legal defeasance or covenant defeasance, including any modifications to the provisions described above, with respect to the debt securities of a particular series.

#### Subordination
The terms and conditions, if any, upon which the debt securities of any series will be subordinated to other indebtedness of the Operating Partnership, including the debt securities of other series, will be set forth in the applicable prospectus supplement. These terms will include a description of the indebtedness ranking senior to the debt securities of that series, the restrictions on payments to the holders of the debt securities of that series while a default with respect to the senior indebtedness is continuing, the restrictions, if any, on payments to the holders of the debt securities of that series following an event of default, and provisions requiring holders of the debt securities of that series to remit certain payments to holders of senior indebtedness.

#### Book-Entry System and Global Securities
The debt securities of a series may be issued in whole or in part in the form of one or more securities in global form that will be deposited with, or on behalf of, a depository identified in the applicable prospectus supplement relating to that series. Global securities, if any, issued in the United States are expected to be deposited with The Depository Trust Company, or DTC, as depository. Unless otherwise indicated, global securities will be issued in fully registered form and in either temporary or permanent form. Unless the applicable prospectus supplement states otherwise, and until it is exchanged in whole or in part for the debt securities represented thereby, a global security may not be transferred except as a whole by the depository for that global security to a nominee of that depository or by a nominee of that depository to that depository or another nominee of such depository or by that depository or any nominee of that depository to a successor depository or any nominee of that successor.

The specific terms of the depository arrangement with respect to a series of debt securities will be described in the applicable prospectus supplement. We anticipate that, unless otherwise indicated in the applicable prospectus supplement, the following provisions will apply to depository arrangements.

The applicable prospectus supplement will state whether the global securities will be issued in certificated or book-entry form. If the global securities are to be issued in book-entry form, we expect that upon the issuance of a global security, the depository for the global security or its nominee will credit on its book-entry registration and transfer system the respective principal amounts of the individual debt securities represented by the global security to the accounts of persons that have accounts with such depository, or participants. These accounts will be designated by the underwriters, dealers or agents with respect to the debt securities. Ownership of beneficial interests in a global security will be limited to participants or persons that may hold interests through participants.

We expect that, for the global securities deposited with DTC, pursuant to procedures established by DTC, ownership of beneficial interests in any global security with respect to which DTC is the depository will be shown on, and the transfer of that ownership will be effected only through, records maintained by DTC or its nominee (with respect to beneficial interests of participants) and records of participants (with respect to beneficial interests of persons who hold through participants). None of the Operating Partnership, the guarantors, the trustee, any paying agent and the security registrar will have any responsibility or liability for any aspect of the records of DTC or for maintaining, supervising or reviewing any records of DTC or any of its participants relating to beneficial ownership interests in the debt securities.

------

[**TABLE OF CONTENTS**](#TOC)

The laws of some states require that certain purchasers of securities take physical delivery of such securities in definitive form. These limits and laws may impair the ability to own, pledge or transfer beneficial interest in a global security.

Unless otherwise specified in the applicable prospectus supplement or the actual global security, so long as the depository for a global security or its nominee is the registered owner of the book-entry global security, the depository or that nominee, as the case may be, will be considered the sole owner or holder of the debt securities represented by that global security for all purposes under the applicable indenture. Except as described below or in the applicable prospectus supplement or the global security, owners of beneficial interest in a global security will not be entitled to have any of the individual debt securities represented by the global security registered in their names, will not receive or be entitled to receive delivery of debt securities in definitive certificated form and will not be considered the owners or holders thereof under the applicable indenture. Beneficial owners of debt securities evidenced by a global security will not be considered the owners or holders thereof under the indenture for any purpose, including with respect to the giving of any direction, instructions or approvals to the trustee thereunder. Accordingly, each person owning a beneficial interest in a global security with respect to which DTC is the depository must rely on the procedures of DTC and, if that person is not a participant, on the procedures of the participant through which that person owns its interests, to exercise any rights of a holder under the applicable indenture. We understand that, under existing industry practice, if we request any action of holders or if an owner of a beneficial interest in a global security desires to give or take any action which a holder is entitled to give or take under the applicable indenture, DTC would authorize the participants holding the relevant beneficial interest to give or take that action, and the participants would authorize beneficial owners through the participants to give or take that action or would otherwise act upon the instructions of beneficial owners holding through them.

Payments of principal of and premium, if any, and interest on debt securities represented by a global security registered in the name of a depository or its nominee will be made to or at the direction of the depository or its nominee, as the case may be, as the registered owner of the global security under the indenture. Under the terms of the indenture, the Operating Partnership, the guarantors, the trustee, any paying agent and the security registrar may treat the persons in whose name debt securities, including a global security, are registered as the owners thereof for the purpose of receiving such payments. Consequently, none of the Operating Partnership, the guarantors, the trustee, any paying agent and the security registrar has or will have any responsibility or liability for the payment of those amounts to beneficial owners of debt securities (including principal, premium, if any, and interest). We believe, however, that it is currently the policy of DTC to immediately credit the accounts of relevant participants with payments, in amounts proportionate to their respective holdings of beneficial interests in the relevant global security as shown on the records of DTC or its nominee. Payments by participants to owners of beneficial interests in the global security held through participants will be governed by standing instructions and customary practices, as is the case with securities held for the account of customers in bearer form or registered in street name, and will be the responsibility of the participants. Redemption notices with respect to any debt securities represented by a global security will be sent to the depository or its nominee. If less than all of the debt securities of any series are to be redeemed, we expect the depository to determine the amount of the interest of each participant in the debt securities to be redeemed to be determined by lot. None of the Operating Partnership, the guarantors, the trustee, any paying agent and the security registrar for the debt securities will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in the global security for the debt securities or for maintaining any records with respect thereto.

None of the Operating Partnership, the guarantors, the trustee, any paying agent and the security registrar will be liable for any delay by the holders of a global security or the depository in identifying the beneficial owners of debt securities and the Operating Partnership, the guarantors and the trustee may conclusively rely on, and will be protected in relying on, instructions from the holder of a global security or the depository for all purposes. The rules applicable to DTC and its participants are on file with the SEC.

If a depository for any debt securities is at any time unwilling, unable or ineligible to continue as depository and a successor depository is not appointed by the Operating Partnership within 90 days, the Operating Partnership will issue definitive certificated debt securities in exchange for the global security representing those debt securities. If an event of default has occurred and is continuing with respect to the

------

[**TABLE OF CONTENTS**](#TOC)

debt securities of any series, the Operating Partnership will issue definitive certificated debt securities in exchange for the global security or securities representing the debt securities of such series. In addition, the Operating Partnership may at any time and in its sole discretion, subject to any limitations described in the applicable prospectus supplement or the global security relating to the debt securities, determine not to have any of the debt securities represented by one or more global securities and in such event will issue definitive certificated debt securities in exchange for the global security or securities representing the debt securities.

The debt securities of a series may also be issued in whole or in part in the form of one or more bearer global securities that will be deposited outside of the United States with a depository, or with a nominee for the depository, identified in the applicable prospectus supplement and/or global security. Any such bearer global securities may be issued in temporary or permanent form. The specific terms and procedures, including the specific terms of the depository arrangement, with respect to any portion of a series of debt securities to be represented by one or more bearer global securities will be described in the applicable prospectus supplement and/or global security.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • which in either case, are full faith and credit obligations of the United States of America or that other government, and are not callable or redeemable at the option of the issuer thereof, and will also include a depositary receipt issued by a bank or trust company as custodian with respect to any such Government Obligation or a specific payment of interest on or principal of any such Government Obligation held by that custodian for the account of the holder of a depositary receipt, provided that (except as required by law) the custodian is not authorized to make any deduction from the amount payable to the holder of that depositary receipt from any amount received by the custodian in respect of the Government Obligation or the specific payment of interest on or principal of the Government Obligation evidenced by such depositary receipt.

"*Subsidiary*" means, as to any person, (a) any corporation more than 50% of whose stock of any class or classes having by the terms thereof ordinary voting power to elect a majority of the directors of such corporation (irrespective of whether or not at the time, any class or classes of stock of such corporation shall have or might have voting power by reason of the lapse of time or the happening of any contingency) is at the time owned by such person directly or indirectly through Subsidiaries, and (b) any partnership, association, joint venture, limited liability company, trust or other entity in which such person directly or indirectly through Subsidiaries has more than a 50% equity interest or 50% Capital Percentage at any time.

#### PLAN OF DISTRIBUTION

#### Sales by Us
We may sell the securities from time to time in one or more transactions, including block transactions and transactions on the NYSE or on a delayed or continuous basis, in each case:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • through underwriters or dealers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • through agents;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • directly to one or more purchasers, including our affiliates;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • directly to shareholders;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • through block trades;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • through a combination of any of these methods of sale; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • in any other manner, as provided in the applicable prospectus supplement.

The securities may be sold at a fixed price or prices, which may be changed, or at market prices prevailing at the time of sale, at prices relating to the prevailing market prices or at negotiated prices. The consideration may be cash or another form negotiated by the parties. Agents, underwriters or broker-dealers may be paid compensation for offering and selling the securities. That compensation may be in the form of discounts, concessions or commissions to be received from us or from the purchasers of the securities.

For each offering of common shares, preferred shares, depositary shares, subscriptions rights, warrants or debt securities, the prospectus supplement or other offering materials will describe the specific plan, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the terms of the offering and the specific plan of distribution;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the name or names of any underwriters, dealers, agents or direct purchasers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the purchase price of the securities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • any delayed delivery arrangements;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • any commissions paid to agents and any underwriting discounts, commissions or other items constituting underwriters' compensation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • any discounts or concessions allowed or reallowed or paid to dealers; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • any other applicable terms of the specific offering.

If we use underwriters for a sale of securities, the underwriters may offer and sell the securities at a fixed price or prices, which may be changed, or from time to time at market prices prevailing at the time of sale, at prices related to such prevailing market prices, at negotiated prices or under delayed delivery contracts or other contractual commitments. We also may, from time to time, authorize underwriters acting as agents to offer and sell the securities upon the terms and conditions set forth in any prospectus supplement. Underwriters may sell the securities to or through dealers, and such dealers may receive compensation in the form of discounts, concessions or commissions (which may be changed from time to time) from the underwriters and/or from the purchasers for whom they may act as agent.

Offers to purchase the securities may be solicited by agents designated by us from time to time. Any such agent involved in the offer or sale of the securities will be named, and any commissions payable by the Company to such agent will be set forth in the prospectus supplement. Unless otherwise indicated in the prospectus supplement, any such agent will be acting on a reasonable best efforts basis for the period of its appointment. Any such agent may be deemed to be an underwriter, as that term is defined in the Securities Act, of the securities so offered and sold.

We may from time to time engage a firm to act as our agent for one or more offerings of our securities. We sometimes refer to this agent as our "offering agent." If we reach agreement with an offering agent with respect to a specific offering, including the number of securities and any minimum price below which sales

------

[**TABLE OF CONTENTS**](#TOC)

may not be made, then the offering agent will try to sell such securities on the agreed terms. The offering agent could make sales in privately negotiated transactions and/or any other method permitted by law, including sales deemed to be an "at-the-market" offering as defined in Rule 415 promulgated under the Securities Act, including sales made directly on the NYSE, or sales made to or through a market maker other than on an exchange. The offering agent will be deemed to be an "underwriter" within the meaning of the Securities Act with respect to any sales effected through an "at-the-market" offering.

If an underwriter or underwriters are utilized in the sale of securities, we will execute an underwriting agreement with such underwriter or underwriters at the time an agreement for such sale is reached, and the names of the specific managing underwriter or underwriters, as well as any other underwriters, and the terms of the transactions, including compensation of the underwriters and dealers, if any, will be set forth in the prospectus supplement, which will be used by the underwriters to resell the securities.

If a dealer is utilized in the sale of the securities, we may sell such securities to the dealer, as principal. The dealer may then resell such securities to the public at varying prices to be determined by such dealer at the time of resale. The name of the dealer and the terms of the transactions will be set forth in the prospectus supplement relating thereto.

Offers to purchase the securities may be solicited directly by us and sales thereof may be made by us directly to institutional investors or others. The terms of any such sales, including the terms of any bidding or auction prices, if utilized, will be described in the prospectus supplement relating thereto.

We may enter into derivative transactions with third parties, or sell securities not covered by this prospectus to third parties in privately negotiated transactions. If disclosed in the applicable prospectus supplement, in connection with those derivative transactions third parties may sell securities covered by this prospectus and such prospectus supplement, including in short sale transactions. If so, the third party may use securities pledged by us or borrowed from us or from others to settle those short sales or to close out any related open borrowings of securities, and may use securities received from us in settlement of those derivative transactions to close out any related open borrowings of securities. If the third party is or may be deemed to be an underwriter under the Securities Act, it will be identified in the applicable prospectus supplements.

Some or all of the securities that we offer through this prospectus may be new issues of securities with no established trading market. We are not making an offer of securities in any state that does not permit such an offer.

If indicated in the applicable prospectus supplement, we may authorize underwriters or other persons acting as our agents to solicit offers by institutions or other suitable purchasers to purchase the securities from us at the public offering price set forth in the prospectus supplement, pursuant to delayed delivery contracts providing for payment and delivery on the date or dates stated in the prospectus supplement. These purchasers may include, among others, commercial and savings banks, insurance companies, pension funds, investment companies, educational and charitable institutions and other institutions, but will in all cases be subject to our approval. Delayed delivery contracts will be subject to the condition that the purchase of the securities covered by the delayed delivery contracts will not at the time of delivery be prohibited under the laws of any jurisdiction in the United States to which the purchaser is subject. The underwriters and agents will not have any responsibility with respect to the validity or performance of these contracts.

To facilitate the offering of the securities, certain persons participating in the offering may engage in transactions that stabilize, maintain, or otherwise affect the price of the securities. This may include over-allotments or short sales of the securities, which involves the sale by persons participating in the offering of more securities than we sold to them. In these circumstances, these persons would cover the over-allotments or short positions by making purchases in the open market or by exercising their over-allotment option. In addition, these persons may stabilize or maintain the price of the securities by bidding for or purchasing securities in the open market or by imposing penalty bids, whereby selling concessions allowed to dealers participating in the offering may be reclaimed if securities sold by them are repurchased in connection with stabilization transactions. The effect of these transactions may be to stabilize or maintain the market price of the securities at a level above that which might otherwise prevail in the open market. These transactions may be discontinued at any time.

------

[**TABLE OF CONTENTS**](#TOC)

Underwriters, dealers and agents participating in the distribution of the securities may be deemed to be underwriters, and any discounts and commissions received by them from us or from purchasers of the securities and any profit realized by them on resale of the securities may be deemed to be underwriting discounts and commissions under the Securities Act. If such dealers or agents were deemed to be underwriters, they may be subject to statutory liabilities under the Securities Act. Underwriters, dealers and agents may be entitled, under agreements entered into with us, to indemnification against and contribution toward certain civil liabilities, including liabilities under the Securities Act.

In the ordinary course of business, we may engage in transactions with underwriters, dealers, agents and their affiliates and they may perform services for us.

The selling securityholders may resell or redistribute the securities from time to time on any stock exchange or automated interdealer quotation system on which the securities are listed, in the over-the-counter market, in privately negotiated transactions, or in any other legal manner, at fixed prices that may be changed, at market prices prevailing at the time of sale, at prices related to prevailing market prices or at negotiated prices. Persons who are pledgees, donees, transferees, or other successors in interest of any of the named selling securityholders (including but not limited to persons who receive securities from a named selling securityholder as a gift, partnership distribution or other nonsale-related transfer after the date of this prospectus) may also use this prospectus and are included when we refer to "selling securityholders" in this prospectus. The selling securityholders may sell the securities by one or more of the following methods, without limitation:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • block trades (which may include cross trades) in which the broker or dealer so engaged will attempt to sell the securities as agent but may position and resell a portion of the block as principal to facilitate the transaction;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • purchases by a broker or dealer as principal and resale by the broker or dealer for its own account;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • an exchange distribution or secondary distribution in accordance with the rules of any stock exchange on which the securities may be listed;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • ordinary brokerage transactions and transactions in which the broker solicits purchases;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • an offering at other than a fixed price on or through the facilities of any stock exchange on which the securities are listed or to or through a market maker other than on that stock exchange;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • privately negotiated transactions, directly or through agents;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • short sales;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • through the writing of options on the securities, whether or the options are listed on an options exchange;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • through the distribution of the securities by any securityholders to its partners, members or shareholders;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • one or more underwritten offerings;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • agreements between a broker or dealer and any securityholder to sell a specified number of the securities at a stipulated price per share; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • any combination of any of these methods of sale or distribution, or any other method permitted by applicable law.

The selling securityholders may also transfer the securities by gift.

The selling securityholders may engage brokers and dealers, and any brokers or dealers may arrange for other brokers or dealers to participate in effecting sales of the securities. These brokers, dealers or underwriters may act as principals, or as an agent of a selling securityholder. Broker-dealers may agree with a selling securityholder to sell a specified number of the securities at a stipulated price per share. If the broker-dealer is unable to sell securities acting as agent for a selling securityholder, it may purchase as principal any

------

[**TABLE OF CONTENTS**](#TOC)

unsold securities at the stipulated price. Broker-dealers who acquire securities as principals may thereafter resell the securities from time to time in transactions in any stock exchange or automated interdealer quotation system on which the securities are then listed, at prices and on terms then prevailing at the time of sale, at prices related to the then-current market price or in negotiated transactions. Broker-dealers may use block transactions and sales to and through broker-dealers, including transactions of the nature described above.

From time to time, one or more of the selling securityholders may pledge, hypothecate or grant a security interest in some or all of the securities owned by them. The pledgees, secured parties or persons to whom the securities have been hypothecated will, upon foreclosure in the event of default, be deemed to be selling securityholders. The number of a selling securityholder's securities offered under this prospectus will decrease as and when it takes such actions. The plan of distribution for that selling securityholder's securities will otherwise remain unchanged. In addition, a selling securityholder may, from time to time, sell the securities short, and, in those instances, this prospectus may be delivered in connection with the short sales and the securities offered under this prospectus may be used to cover short sales.

The selling securityholders and any underwriters, brokers, dealers or agents that participate in the distribution of the securities may be deemed to be "underwriters" within the meaning of the Securities Act, and any discounts and commissions received by them from us or from purchasers of the securities and any profit realized by them on resale of the securities may be deemed to be underwriting discounts and commissions under the Securities Act.

A selling securityholder may enter into hedging transactions with broker-dealers and the broker-dealers may engage in short sales of the securities in the course of hedging the positions they assume with that selling securityholder, including, without limitation, in connection with distributions of the securities by those broker-dealers. A selling securityholder may enter into option or other transactions with broker-dealers that involve the delivery of the securities offered hereby to the broker-dealers, who may then resell or otherwise transfer those securities. A selling securityholder may also loan or pledge the securities offered hereby to a broker-dealer and the broker-dealer may sell the securities offered hereby so loaned or upon a default may sell or otherwise transfer the pledged securities offered hereby.

The selling securityholders and other persons participating in the sale or distribution of the securities will be subject to applicable provisions of the Exchange Act and the related rules and regulations adopted by the SEC, including Regulation M. This regulation may limit the timing of purchases and sales of any of the securities by the selling securityholders and any other person. The anti-manipulation rules under the Exchange Act may apply to sales of securities in the market and to the activities of the selling securityholders and their affiliates. Furthermore, Regulation M may restrict the ability of any person engaged in the distribution of the securities to engage in market-making activities with respect to the particular securities being distributed for a period of up to five business days before the distribution. These restrictions may affect the marketability of the securities and the ability of any person or entity to engage in market-making activities with respect to the securities.

We may agree to indemnify the selling securityholders and their respective officers, directors, employees and agents, and any underwriter or other person who participates in the offering of the securities, against specified liabilities, including liabilities under the federal securities laws or to contribute to payments the underwriters may be required to make in respect of those liabilities. The selling securityholders may agree to indemnify us, the other selling securityholders and any underwriter or other person who participates in the offering of the securities, against specified liabilities arising from information provided by the selling securityholders for use in this prospectus or any accompanying prospectus supplement, including liabilities under the federal securities laws. In each case, indemnification may include each person who is an affiliate of or controls one of these specified indemnified persons within the meaning of the federal securities laws or is required to contribute to payments the underwriters may be required to make in respect of those liabilities. The selling securityholders may agree to indemnify any brokers, dealers or agents who participate in transactions involving sales of the securities against specified liabilities arising under the federal securities laws in connection with the offering and sale of the securities.

We will not receive any proceeds from sales of any securities by the selling securityholders.

We cannot assure you that the selling securityholders will sell all or any portion of the securities offered.

We will supply the selling securityholders and any stock exchange upon which the securities are listed with reasonable quantities of copies of this prospectus. To the extent required by Rule 424 under the Securities Act in connection with any resale or redistribution by a selling securityholder, we will file a prospectus supplement setting forth:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the aggregate number of securities to be sold;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the public offering price;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the names of any underwriter, agent or broker-dealer, if applicable; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • any applicable commissions, discounts, concessions, fees or other items constituting compensation to underwriters, agents or broker-dealers with respect to the particular transaction (which may exceed customary commissions or compensation).

If a selling securityholder notifies us that a material arrangement has been entered into with a broker-dealer for the sale of securities through a block trade, special offering, exchange, distribution or secondary distribution or a purchase by a broker or dealer, the prospectus supplement will include any other facts that are material to the transaction. If applicable, this may include a statement to the effect that the participating broker-dealers did not conduct any investigation to verify the information set forth or incorporated by reference in this prospectus.

#### Item 15. Indemnification of Directors and Officers
 *CubeSmart* 

The Maryland REIT Law permits a Maryland REIT to include in its declaration of trust a provision limiting the liability of its trustees and officers to the trust and CubeSmart's shareholders for money damages except for liability resulting from (a) actual receipt of an improper benefit or profit in money, property or services or (b) active or deliberate dishonesty established in a judgment or other final adjudication to be material to the cause of action. CubeSmart's declaration of trust contains a provision that limits the liability of CubeSmart's trustees and officers to the maximum extent permitted by Maryland law.

The Maryland REIT Law permits a Maryland REIT to indemnify and advance expenses to its trustees, officers, employees and agents to the same extent as permitted by the Maryland General Corporation Law, or the MGCL, for directors and officers of Maryland corporations. The MGCL permits a corporation to indemnify its present and former directors and officers, among others, against judgments, penalties, fines, settlements and reasonable expenses actually incurred by them in connection with any proceeding to which they may be made or threatened to be made a party by reason of their service in those or other capacities unless it is established that (a) the act or omission of the director or officer was material to the matter giving rise to the proceeding and (i) was committed in bad faith or (ii) was a result of active and deliberate dishonesty, (b) the director or officer actually received an improper personal benefit in money, property or services or (c) in the case of any criminal proceeding, the director or officer had reasonable cause to believe that the act or omission was unlawful. However, a Maryland corporation may not indemnify for an adverse judgment in a suit by or in the right of the corporation or if the director or officer was adjudged to be liable to the corporation nor may a director or officer be indemnified in circumstances in which the director or officer is found liable for an improper personal benefit, unless in either case a court orders indemnification and then only for expenses. In accordance with the MGCL and CubeSmart's bylaws, as a condition to advancement of expenses, CubeSmart is required to obtain (a) a written affirmation by the trustee or officer of his good faith belief that he has met the standard of conduct necessary for indemnification and (b) a written statement by him or on his behalf to repay the amount paid or reimbursed by us if it shall ultimately be determined that the standard of conduct was not met.

CubeSmart's declaration of trust provides that it shall indemnify, to the maximum extent permitted by Maryland law in effect from time to time, any individual who is a present or former trustee or officer (including any individual who, at CubeSmart's request, serves or has served as an officer, partner, employee

------

[**TABLE OF CONTENTS**](#TOC)

or agent of another corporation, partnership, joint venture, trust, employee benefit plan or any other enterprise) from and against any claim or liability to which such person may become subject by reason of service in such capacity. CubeSmart has the power, with the approval of CubeSmart's board of trustees, to provide indemnification and advancement of expenses to a present or former trustee or officer who served a predecessor of CubeSmart in any of the capacities described above and to any employee or agent of CubeSmart or a predecessor of CubeSmart. Maryland law requires us to indemnify a trustee or officer who has been successful, on the merits or otherwise, in the defense of any proceeding to which he is made a party by reason of his service in that capacity.

The above discussion of CubeSmart's declaration of trust and bylaws and of the MGCL is not intended to be exhaustive and is qualified in its entirety by such declaration of trust, bylaws and statutes.

CubeSmart has entered into and expects to continue to enter into indemnification agreements with each of its executive officers and trustees whereby CubeSmart indemnifies such executive officers and trustees to the fullest extent permitted by Maryland law against all expenses and liabilities, subject to limited exceptions.

 *CubeSmart, L.P.* 

To the fullest extent permitted by applicable law, the partnership agreement of CubeSmart, L.P., referred to in the prospectus as the "Operating Partnership," provides for indemnification of our general partner, any limited partners and any of our (and our general partner's) officers, directors or trustees and other persons as our general partner may designate from and against any and all losses, claims, damages, liabilities, joint and several, expenses, judgments, fines, settlements and other amounts incurred in connection with any actions relating to our operations, unless it is established by a final determination of a court of competent jurisdiction that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the act or omission of the indemnitee was material to the matter giving rise to the proceeding and either was committed in bad faith or was the result of active and deliberate dishonesty;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • the indemnitee actually received an improper personal benefit in money, property or services; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; • indemnitee had reasonable cause to believe that the act or omission was unlawful.

The Operating Partnership has also entered into indemnification agreements with each of CubeSmart's executive officers whereby it indemnifies them to the fullest extent permitted by Maryland law against all expenses and liabilities, subject to limited exceptions.

Incorporated herein by reference as above indicated.

\*\*

To be filed by amendment or as an exhibit to a document to be incorporated by reference in connection with the offering of the securities registered hereunder.

#### Item 17. Undertakings
The undersigned registrants hereby undertake:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (1)

To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (i)

To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (ii)

To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in the volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Securities and Exchange Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration statement; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (iii)

To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

*provided, however*, that paragraphs (1)(i), (1)(ii) or (1)(iii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Securities and Exchange Commission by the registrants pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement, or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (2)

That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (3)

To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (4)

That, for the purpose of determining liability under the Securities Act of 1933 to any purchaser:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (i)

If the registrants are relying on Rule 430B:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (A)

Each prospectus filed by the registrants pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (B)

Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5) or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof; provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (ii)

If the registrants are subject to Rule 430C, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness; *provided, however*, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (5)

That, for the purpose of determining liability of the registrants under the Securities Act of 1933 to any purchaser in the initial distribution of the securities, the undersigned registrants undertake that in a primary offering of securities of the undersigned registrants pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrants will be sellers to the purchaser and will be considered to offer or sell such securities to such purchaser:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (i)

Any preliminary prospectus or prospectus of the undersigned registrants relating to the offering required to be filed pursuant to Rule 424;

------

[**TABLE OF CONTENTS**](#TOC)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (ii)

Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrants or used or referred to by the undersigned registrants;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (iii)

The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrants or their respective securities provided by or on behalf of the undersigned registrants; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (iv)

Any other communication that is an offer in the offering made by the undersigned registrants to the purchaser.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (6)

That, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of the securities at that time shall be deemed to be the initial bona fide offering thereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (7)

Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers or controlling persons of the registrants pursuant to the foregoing provisions, or otherwise, the registrants have been advised that in the opinion of the Securities and Exchange Commission this type of indemnification is against public policy as expressed in the Securities Act of 1933 and is therefore unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrants of expenses incurred or paid by their respective director, officer or controlling person of such registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrants will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (8)

To file an application for the purpose of determining the eligibility of the trustee to act under subsection (a) of Section 310 of the Trust Indenture Act in accordance with the rules and regulations prescribed by the Securities and Exchange Commission under Section 305(b)(2) of the Trust Indenture Act.

We have acted as counsel to CubeSmart, a Maryland real estate investment trust (the "<u>Company</u>"), and CubeSmart, L.P., a Delaware limited partnership (the "<u>Partnership</u>" and together with the Company, the "<u>Registrants</u>"), in connection with the filing by the Registrants of a Registration Statement on Form S-3 (the "<u>Registration Statement</u>") with the Securities and Exchange Commission (the "<u>Commission</u>") on March 3, 2023, relating to the registration of: (1) (a) common shares of beneficial interest, $.01 par value per share, of the Company ("<u>Common Shares</u>"), (b) one or more series of preferred shares of beneficial interest, $.01 par value per share, of the Company ("<u>Preferred Shares</u>"), (c) one or more series of Preferred Shares represented by depositary shares ("<u>Depositary Shares</u>"), (d) subscription rights to purchase Common Shares, Preferred Shares or Depositary Shares ("<u>Subscription Rights</u>"), and (e) warrants to purchase Common Shares, Preferred Shares or Depositary Shares ("<u>Warrants</u>") and (2) debt securities of the Partnership ("<u>Debt Securities</u>"), which will be fully and unconditionally guaranteed by the Company ("<u>Guarantees</u>," and together with the Common Shares, the Preferred Shares, the Depositary Shares, the Subscription Rights, the Warrants, and the Debt Securities, collectively, the "<u>Securities</u>").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;H. Such other documents and matters as we have deemed necessary or appropriate to express the opinion set forth in this letter, subject to the assumptions, limitations and qualifications stated herein.

In expressing the opinion set forth below, we have assumed, and so far as is known to us there are no facts inconsistent with, the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;I. Each natural person executing or delivering any of the Documents is legally competent to do so;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;II. Each individual executing or delivering any of the Documents on behalf of a party (other than the Company or the Partnership) is duly authorized to do so;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;III. Each of the parties (other than the Company or the Partnership) executing or delivering any of the Documents has duly and validly executed and delivered each of the Documents to which such party is a signatory, and such party's obligations set forth therein are legal, valid and binding;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;IV. All Documents submitted to us as originals are authentic. All Documents submitted to us as certified or photostatic copies conform to the original documents. All signatures on all such Documents are genuine. All public records reviewed or relied upon by us or on our behalf are true and complete. All statements and information contained in the Documents and in the factual representations to us by officers of the Company are true and complete. There are no oral or written modifications or amendments to the Documents, by action or conduct of the parties or otherwise;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;V. The Securities will be issued against payment of valid consideration under applicable law; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;VI. The outstanding shares of beneficial interest of the Company have not been and will not be transferred in violation of any restriction or limitation contained in the Declaration. The Securities will not be transferred in violation of any restriction or limitation contained in the Declaration.

For the purposes of the opinions set forth below, we have assumed that the issuance of, and certain terms of, the Securities that may be issued from time to time will have been duly authorized and established by proper action of the Partnership or the Company, as applicable, consistent with the procedures and terms described in the Registration Statement and in accordance with (a) the Certificate, the Partnership Agreement and applicable Delaware law, with respect to the Partnership and (b) the Declaration and Bylaws and applicable Maryland law, with respect to the Company, in a manner that does not violate any law, government or court-imposed order or restriction or agreement or instrument then binding on the Partnership or the Company, respectively, as applicable (the "<u>Authorizing Proceedings</u>").

![](tm238324d2_ex5-1img002.jpg)

In expressing the opinions set forth below, we have further assumed that (i) prior to any issuance of Preferred Shares or Depositary Shares, such Preferred Shares shall be classified in accordance with the Declaration and applicable Maryland law, and appropriate Articles Supplementary to the Declaration shall be duly filed for recordation with the Maryland State Department of Assessments and Taxation; (ii) any Depositary Shares will be issued by a depositary (as defined below) under one or more deposit agreements (each, a "<u>Deposit Agreement</u>"), each between the Company and a financial institution identified therein as depositary (each, a "<u>Depositary</u>"), that create legal, valid and binding obligations of the parties thereto (other than the Company); (iii) the Subscription Rights will be issued under one or more subscription agreements that create legal, valid and binding obligations of the parties thereto (other than the Company), (iv) the Warrants will be issued under one or more warrant agreements (each a "<u>Warrant Agreement</u>") that create legal, valid and binding obligations of the parties thereto (other than the Company); (v) the Debt Securities will be issued pursuant to and governed by the Indenture that creates legal, valid and binding obligations of the parties thereto (other than the Partnership); and (vi) the Trustee will be duly organized, validly existing and in good standing under the laws of its jurisdiction of organization and will be in compliance, generally, and with respect to acting as a Trustee, under the Indenture and all applicable laws and regulations.

Based upon the foregoing, and subject to the assumptions, limitations and qualifications stated herein, we are of the opinion that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. Upon the completion of all Authorizing Proceedings relating to the Securities that are Common Shares and the due execution, countersignature and delivery of certificates evidencing such Common Shares, and assuming that at the time of any offering or sale of such Common Shares, the Company shall have such number of Common Shares as are included in such offering or sale, authorized and available for issuance, the Common Shares will be duly authorized and, when and if delivered against payment therefor in accordance with the resolutions of the Board of Trustees of the Company, or a duly authorized and empowered committee thereof, authorizing their issuance, will be validly issued, fully paid and nonassessable.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. Upon the completion of all Authorizing Proceedings relating to the Securities that are Preferred Shares and upon the classification of such Preferred Shares in accordance with applicable law and the filing of appropriate Articles Supplementary to the Declaration and the due execution, countersignature and delivery of certificates evidencing such Preferred Shares, and assuming that at the time of any offering or sale of such Preferred Shares, the Company shall have such number of Preferred Shares as are included in such offering or sale, authorized and available for issuance, the Preferred Shares will be duly authorized and, when and if delivered against payment therefor in accordance with the resolutions of the Board of Trustees of the Company, or a duly authorized and empowered committee thereof, authorizing their issuance, will be validly issued, fully paid and nonassessable.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. Upon the completion of all Authorizing Proceedings relating to a Deposit Agreement and a series of Preferred Shares underlying a series of Depositary Shares (and subject to the assumption expressed in opinion paragraph 2 above), and upon the classification of such Preferred Shares in accordance with applicable law and the filing of appropriate Articles Supplementary to the Declaration and the due execution, countersignature and delivery of the Deposit Agreement and certificates evidencing the Preferred Shares and depositary receipts evidencing the Depositary Shares (the "<u>Depositary Receipts</u>") in the form provided by a Deposit Agreement, and when delivered against payment therefor in accordance with the resolutions of the Board of Trustees, or a duly authorized and empowered committee thereof, authorizing their issuance, such Depositary Shares will be validly issued and will entitle the holders thereof to the rights specified in the Depositary Receipts and the Deposit Agreement for such Depositary Shares except as such rights may be limited by bankruptcy, insolvency, reorganization or similar laws affecting creditors' rights generally, and subject to general principles of equity (regardless of whether enforcement is sought in a proceeding in equity or at law).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. Upon completion of all Authorizing Proceedings relating to Securities that are Subscription Rights and the due execution, authentication and delivery of certificates representing such Subscription Rights, and assuming that at the time of any offering or sale of such Subscription Rights, the Company shall have such number of Common Shares, Preferred Shares and/or Depositary Shares as are issuable upon exercise of such Subscription Rights, authorized and available for issuance (subject to the assumptions expressed in opinion paragraphs 1, 2 and 3 above), and when delivered against payment therefor in accordance with the resolutions of the Board of Trustees of the Company, or a duly authorized and empowered committee thereof, authorizing their issuance, the Subscription Rights will be duly authorized and will be binding obligations of the Company, enforceable against the Company in accordance with their respective terms, except as such enforceability may be limited by bankruptcy, insolvency, reorganization or similar laws affecting creditors' rights generally, and subject to general principles of equity (regardless of whether enforcement is sought in a proceeding in equity or at law).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5. Upon completion of all Authorizing Proceedings relating to Securities that are Warrants and the due execution, authentication and delivery of the Warrant Agreement and certificates representing such Warrants, and assuming that at the time of any offering or sale of such Warrants, the Company shall have such number of Common Shares, Preferred Shares and/or Depositary Shares as are issuable upon exercise of such Warrants, authorized and available for issuance (subject to the assumptions expressed in opinion paragraphs 1, 2 and 3 above), and when delivered against payment therefor in accordance with the resolutions of the Board of Trustees of the Company, or a duly authorized and empowered committee thereof, authorizing their issuance, the Warrants will be duly authorized and will be binding obligations of the Company, enforceable against the Company in accordance with their respective terms, except as such enforceability may be limited by bankruptcy, insolvency, reorganization or similar laws affecting creditors' rights generally, and subject to general principles of equity (regardless of whether enforcement is sought in a proceeding in equity or at law).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7. Upon completion of all Authorizing Proceedings relating to Securities that are Guarantees, and upon the due execution and delivery of the Guarantees pursuant to the Indenture, the Guarantees will be duly authorized by all necessary action of the Company, and such Guarantees will be legally issued and will be binding obligations of the Company, enforceable against the Company in accordance with their terms, except as such enforceability may be limited by bankruptcy, insolvency, reorganization or similar laws affecting creditors' rights generally, and subject to general principles of equity (regardless of whether enforcement is sought in a proceeding in equity or at law).

We express no opinion herein as to the laws of any state or jurisdiction other than the laws of the State of Delaware and the State of Maryland and the federal laws of the United States of America.

We assume no obligation to supplement this opinion if any applicable law changes after the date hereof or if we become aware of any fact that might change the opinion expressed herein after the date hereof.

CubeSmart

CubeSmart, L.P.

5 Old Lancaster Road

Malvern, Pennsylvania 19355

Ladies and Gentlemen:

We have acted as counsel to CubeSmart, a Maryland real estate investment trust (the "<u>Company</u>") and CubeSmart, L.P., a Delaware limited partnership (the "<u>Partnership</u>"), in connection with the preparation of the Registration Statement on Form S-3 filed by the Company and the Partnership under the Securities Act of 1933, as amended (the "<u>1933 Act</u>"), with the Securities and Exchange Commission (the "<u>Commission</u>") on March 3, 2023 (the "<u>Registration Statement</u>"). Any capitalized terms used but not defined herein shall have the meanings given to such terms in the Registration Statement.

The opinions expressed herein are based on the Internal Revenue Code of 1986, as amended (the "<u>Code</u>"), Treasury regulations thereunder (including proposed and temporary Treasury regulations) and interpretations of the foregoing as expressed in court decisions, legislative history and administrative determinations of the Internal Revenue Service (the "<u>IRS</u>") (including its practices and policies in issuing private letter rulings, which are not binding on the IRS, except with respect to a taxpayer that receives such a ruling), all as of the date hereof. This opinion represents our best legal judgment with respect to the probable outcome on the merits and is not binding on the IRS or the courts. There can be no assurance that positions contrary to our opinion will not be taken by the IRS, or that a court considering the issues would not reach a conclusion contrary to such opinions. No assurance can be given that future legislative, judicial or administrative changes, on either a prospective or retroactive basis, would not adversely affect the opinions expressed herein.

In rendering the opinions expressed herein, we have examined such statutes, regulations, records, certificates and other documents as we have considered necessary or appropriate as a basis for such opinions, including: (1) the Articles of Restatement of the Declaration of Trust of the Company dated May 27, 2015, as amended or supplemented through the date hereof and (2) the Second Amended and Restated Agreement of Limited Partnership of the Partnership dated as of October 27, 2004, as amended or supplemented through the date hereof.

In rendering the opinions expressed herein, we have relied upon written representations as to factual matters of the Company and the Partnership contained in an Officer's Certificate Regarding Certain Tax Matters dated March 3, 2023 regarding their consolidated assets, operations and activities (the "<u>Officer's Certificate</u>"). We have not made an independent investigation or audit of the facts set forth in the Officer's Certificate or in any other document. We consequently have relied upon the accuracy of the representations as to factual matters in the Officer's Certificate. After inquiry, we are not aware of any facts or circumstances contrary to, or inconsistent with, the representations that we have relied upon or the other assumptions set forth herein. Our opinion is limited to the tax matters specifically covered herein, and we have not addressed, nor have we been asked to address, any other tax matters relevant to the Company, the Partnership or any other person.

We have assumed, with your consent, that, insofar as relevant to the opinions expressed herein:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1) the Company has been and will be operated in the manner described in the Officer's Certificate, the Registration Statement and the Form 10-K for the fiscal year ended December 31, 2022 (including, in each case, the other documents incorporated therein by reference);

![](tm238324d2_ex8-1img001.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2) all of the obligations imposed by the documents that we reviewed have been and will continue to be performed or satisfied in accordance with their terms; and all of such documents have been properly executed, are valid originals or authentic copies of valid originals, and all signatures thereon are genuine;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3) all representations made in the Officer's Certificate (and other factual information provided to us) are true, correct and complete and will continue to be true, correct and complete, and any representation or statement made in the Officer's Certificate "to the best of knowledge," "to the knowledge" or "to the actual knowledge" of any person(s) or party(ies) or similarly qualified is true, correct and complete as if made without such qualification; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(4) all documents that we have reviewed have been properly executed, are valid originals or authentic copies of valid originals, and all signatures thereon are genuine.

Based upon the foregoing, and subject to the assumptions, limitations and qualifications stated herein, we are of the opinion that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. Commencing with its taxable year ended December 31, 2004, the Company has been organized and operated in conformity with the requirements for qualification as a REIT under the Code, and the Company's current organization and current and proposed method of operation will enable it to continue to meet the requirements for qualification and taxation as a REIT under the Code for its taxable year ending December 31, 2023 and thereafter.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. The discussion in the Registration Statement under the heading "Material United States Federal Income Tax Considerations," to the extent it describes provisions of U.S. federal income tax law and regulations or legal conclusions with respect thereto, is correct in all material respects as of the date hereof.

We assume no obligation to advise you of any changes in our opinion subsequent to the date of this letter. We do not purport to express any opinion herein concerning any law other than the federal income tax law of the United States. The Company's qualification for taxation as a REIT depends upon the Company's ability to meet, on a continuing basis, through actual annual operating and other results, the requirements of the Code, including the requirements with regard to the sources of its gross income, the composition of its assets, the level of its distributions to shareholders and the diversity of its share ownership. We will not review the Company's compliance with these requirements on a continuing basis. Accordingly, no assurance can be given that the actual results of the Company's operations, the sources of its income, the nature of its assets, the level of its distributions to shareholders and the diversity of its share ownership for any given taxable year will satisfy the requirements under the Code for qualification and taxation as a REIT.

We hereby consent to the reference to our firm under the Section "Legal Matters" in the Prospectus included in the Registration Statement and to the filing of this opinion as an exhibit to the Registration Statement. In giving this consent, we do not admit that we are within the category of persons whose consent is required under Section 7 of the 1933 Act.

**<u>Exhibit 1</u>**

**ARTICLES OF ASSOCIATION**

**OF**

**U. S. BANK TRUST COMPANY, NATIONAL ASSOCIATION**

For the purpose of organizing an association (the "Association") to perform any lawful activities of national banks, the undersigned enter into the following Articles of Association:

**FIRST.** The title of this Association shall be U. S. Bank Trust Company, National Association.

**SECOND.** The main office of the Association shall be in the city of Portland, county of Multnomah, state of Oregon. The business of the Association will be limited to fiduciary powers and the support of activities incidental to the exercise of those powers. The Association may not expand or alter its business beyond that stated in this article without the prior approval of the Comptroller of the Currency.

**THIRD.** The board of directors of the Association shall consist of not less than five nor more than twenty-five persons, the exact number to be fixed and determined from time to time by resolution of a majority of the full board of directors or by resolution of a majority of the shareholders at any annual or special meeting thereof. Each director shall own common or preferred stock of the Association or of a holding company owning the Association, with an aggregate par, fair market, or equity value of not less than $1,000, as of either (i) the date of purchase, (ii) the date the person became a director, or (iii) the date of that person's most recent election to the board of directors, whichever is more recent. Any combination of common or preferred stock of the Association or holding company may be used.

Any vacancy in the board of directors may be filled by action of a majority of the remaining directors between meetings of shareholders. The board of directors may increase the number of directors up to the maximum permitted by law. Terms of directors, including directors selected to fill vacancies, shall expire at the next regular meeting of shareholders at which directors are elected, unless the directors resign or are removed from office. Despite the expiration of a director's term, the director shall continue to serve until his or her successor is elected and qualified or until there is a decrease in the number of directors and his or her position is eliminated.

Honorary or advisory members of the board of directors, without voting power or power of final decision in matters concerning the business of the Association, may be appointed by resolution of a majority of the full board of directors, or by resolution of shareholders at any annual or special meeting. Honorary or advisory directors shall not be counted to determined the number of directors of the Association or the presence of a quorum in connection with any board action, and shall not be required to own qualifying shares.

**FOURTH.** There shall be an annual meeting of the shareholders to elect directors and transact whatever other business may be brought before the meeting. It shall be held at the main office or any other convenient place the board of directors may designate, on the day of each year specified therefor in the Bylaws, or if that day falls on a legal holiday in the state in which the Association is located, on the next following banking day. If no election is held on the day fixed or in the event of a legal holiday on the following banking day, an election may be held on any subsequent day within 60 days of the day fixed, to be designated by the board of directors, or, if the directors fail to fix the day, by shareholders representing two-thirds of the shares issued and outstanding. In all cases, at least 10 days' advance notice of the meeting shall be given to the shareholders by first-class mail.

In all elections of directors, the number of votes each common shareholder may cast will be determined by multiplying the number of shares he or she owns by the number of directors to be elected. Those votes may be cumulated and cast for a single candidate or may be distributed among two or more candidates in the manner selected by the shareholder. On all other questions, each common shareholder shall be entitled to one vote for each share of stock held by him or her.

A director may resign at any time by delivering written notice to the board of directors, its chairperson, or to the Association, which resignation shall be effective when the notice is delivered unless the notice specifies a later effective date.

A director may be removed by the shareholders at a meeting called to remove him or her, when notice of the meeting stating that the purpose or one of the purposes is to remove him or her is provided, if there is a failure to fulfill one of the affirmative requirements for qualification, or for cause; provided, however, that a director may not be removed if the number of votes sufficient to elect him or her under cumulative voting is voted against his or her removal.

**FIFTH.** The authorized amount of capital stock of the Association shall be 1,000,000 shares of common stock of the par value of ten dollars ($10) each; but said capital stock may be increased or decreased from time to time, according to the provisions of the laws of the United States. The Association shall have only one class of capital stock.

No holder of shares of the capital stock of any class of the Association shall have any preemptive or preferential right of subscription to any shares of any class of stock of the Association, whether now or hereafter authorized, or to any obligations convertible into stock of the Association, issued, or sold, nor any right of subscription to any thereof other than such, if any, as the board of directors, in its discretion, may from time to time determine and at such price as the board of directors may from time to time fix.

Transfers of the Association's stock are subject to the prior written approval of a federal depository institution regulatory agency. If no other agency approval is required, the approval of the Comptroller of the Currency must be obtained prior to any such transfers.

Unless otherwise specified in the Articles of Association or required by law, (1) all matters requiring shareholder action, including amendments to the Articles of Association must be approved by shareholders owning a majority voting interest in the outstanding voting stock, and (2) each shareholder shall be entitled to one vote per share.

Unless otherwise specified in the Articles of Association or required by law, all shares of voting stock shall be voted together as a class, on any matters requiring shareholder approval.
