CUBESMART
2007 EQUITY INCENTIVE PLAN
PERFORMANCE-VESTED RESTRICTED SHARE UNIT AGREEMENT

Restricted Share Units/Non-transferability	This grant is a Performance Award for up to the maximum number of PSUs set forth on the cover sheet subject to the vesting conditions described below.  Each PSU represents the right to delivery of a Share upon satisfaction of the vesting conditions.  Your PSUs are restricted and  may not be transferred, assigned, pledged or hypothecated, whether by operation of law or otherwise, nor may the Shares potentially subject to delivery upon vesting of PSUs be made subject to execution, attachment or similar process.
Vesting of PSUs and Issuance of Shares	The Company will issue one Share in your name with respect to each PSU that vests pursuant to the terms of this Agreement within thirty (30) days following the date of the expiration of the Performance Period, or such earlier time as PSUs may vest under this Award.
	Your right to the Shares under this Agreement vests up to the maximum number of Shares covered by this grant, as shown on the cover sheet, on the last day of the Performance Period, provided that you continue in service through the last day of the Performance Period.  The number of PSUs that vest, if any, and the number of Shares deliverable following vesting shall be based on the Company’s total shareholder return (appreciation in share price and dividends) (“TSR”), as measured by the average closing stock price during the thirty (30) trading days immediately preceding the first day of the Performance Period and the average closing stock price during the last thirty (30) trading days of the Performance Period, plus aggregate dividends, compared to the TSR of the peer group (consisting of all equity REIT’s) as set forth below:
	If the Company’s TSR for the Performance Period falls in the:	The number of PSUs that vest shall be:
	Upper Quartile (75 percentile and above)	200% of Target
	Third Quartile (50th  to 74th percentile)	Target
	Second Quartile (25th  to 49th percentile)	50% of Target
	Lower Quartile (below 25th percentile)	0%
	The number of PSUs that vest for results (i) above the 25th percentile but less than the 50th percentile and (ii) above the 50th percentile but less than the 75th percentile, will be interpolated.

2

	Other than pursuant to the terms of this Agreement, no PSUs will vest after your service has terminated for any reason unless otherwise provided in a severance plan adopted by the Company in which you are eligible to participate or as determined by the Committee.
Dividend Equivalents	On each of the Company’s dividend payment dates during the Performance Period, the Company shall credit to a bookkeeping account, solely for the purposes of recordkeeping, a number of PSUs equal to the quotient of (x) divided by (y), where (x) is an amount equal to the dividends payable with respect to the maximum number of Shares listed on the cover sheet, and (y) is the closing price of Shares on such dividend payment date, rounded to the nearest whole unit.  As of the last day of the Performance Period (or any earlier vesting date as may be provided for under this Award), PSUs credited to the bookkeeping account (“Dividend PSUs”) shall vest, if at all, to the extent of the product of (a) times (b) where (a) is the total number of Dividend PSUs and (b) is a fraction, the numerator of which is the number of other PSUs that vest under this Award and the denominator of which is the maximum number of Shares listed on the cover sheet.  Vested Dividend PSUs shall be paid in Shares at the same time and subject to the same terms as the underlying vested PSUs.
Change In Control	In the event of a Change in Control before the last day of the Performance Period where the Company is not the surviving corporation (or survives only as a subsidiary of another corporation) (the “Surviving Corporation”), your unvested PSUs under this Agreement shall be fixed at the Target number of PSUs listed on the cover sheet and the Target number of PSUs shall vest on the last day of the Performance Period if you continue in service through the last day of the Performance Period.
Termination in Connection with Change in Control	If (i) the Company is not the Surviving Corporation in a Change in Control, (ii) your unvested PSUs were assumed by, or replaced with a comparable award by, the Surviving Corporation, and (iii) your service terminates without Cause upon or within 12 months following a Change in Control (“Change in Control Termination”), the Target number of PSUs shall vest on the date of termination.  For purposes of this Agreement, the term “Cause” shall have the meanings assigned to such term in any applicable Company severance plan in which you are an eligible employee, or in the absence of such a severance plan, then it shall have the meanings assigned to such term in the Plan.

3

If (i) the Company is not the Surviving Corporation in a Change in Control, (ii) your unvested PSUs that were assumed by, or replaced with a comparable award by, the Surviving Corporation, and (iii) your service terminates because of your death or Disability before the last day of the Performance Period, a pro-rated amount of your unvested PSUs will vest on the last day of the Performance Period, equal to the product of (x) times (y), rounded to the nearest whole unit, where (x) is the Target number of PSUs, and (y) is a fraction, the numerator of which is the number of days that elapsed from January 1, 2017 to the date on which you terminate service, and the denominator of which is 1,095.  For purposes of this Agreement, the term “Disability” shall have the meanings assigned to such term in any applicable Company severance plan in which you are an eligible employee, or in the absence of such a severance plan, then it shall have the meanings assigned to such term in the Plan.

Termination Other than a Change in Control Termination

If you terminate service due to death, Disability, or a Company-initiated termination of service without Cause before the last day of the Performance Period and a Change in Control has not occurred, a pro-rated amount of your PSUs will vest on the last day of the Performance Period, equal to the product of (x) times (y), rounded to the nearest whole unit, where (x) is the number of PSUs that would have vested on the last day of the Performance Period as determined on the same basis as if you had continued in active service through the last day of the Performance Period, and (y) is a fraction, the numerator of which is the number of days that elapse from January 1, 2017 to the date on which you terminate service, and the denominator of which is 1,095, provided further that if you terminate service because of a Company-initiated termination of service without Cause, vesting of your PSUs is also conditioned on your continued adherence to all restrictive covenants and confidentiality obligations you have to the Company or any of its Subsidiaries or Affiliates.

4

Forfeiture of Unvested PSUs	Except as provided pursuant in the provisions of this Agreement, in the event that your service terminates before the last day of the Performance Period for any reason other than death, Disability, or a Company-initiated termination of service without Cause, including in connection with a Change in Control as set forth in this Agreement, you will forfeit to the Company all of the PSUs subject to this grant that have not yet vested.
Recoupment Policy	If it is determined by the Board that your gross negligence, intentional misconduct or fraud caused or partially caused the Company to have to restate all or a portion of its financial statements, the Board, in its sole discretion, may, to the extent permitted by law and to the extent it determines in its sole judgment that it is in the best interests of the Company to do so, require repayment of any Shares delivered to you pursuant to this Agreement or to effect the cancellation of unvested PSUs, if (i) the vesting of the PSUs was calculated based upon, or contingent on, the achievement of financial or operating results that were the subject of, or affected by, the restatement, and (ii) the extent of vesting of PSUs would have been less had the financial statements been correct.  In addition, you agree that you will be subject to any compensation clawback and recoupment policies that may be applicable to you as an employee of the Company, as in effect from time to time and as approved by the Board, whether or not approved before or after the Grant Date.
Withholding Taxes	You agree, as a condition of this grant, that you will make acceptable arrangements to pay any withholding or other taxes that may be due as a result of the vesting of Shares acquired under this grant. In the event that the Company determines that any federal, state, local or foreign tax or withholding payment is required relating to the vesting of Shares arising from this grant, the Company shall have the right to: (i) require such payments from you, (ii) withhold such amounts from other payments due to you from the Company or any Affiliate, or (iii) withhold Shares otherwise payable to you pursuant to this Agreement in an amount equal to the withholding or other taxes due.
Retention Rights	This Agreement does not give you the right to be retained by the Company (or any parent, Subsidiaries or Affiliates) in any capacity.  Furthermore, nothing in the Plan or this Agreement shall be construed to limit the discretion of the Company to terminate your service with the Company at any time, with or without Cause.
No Impact on Other Benefits	The value of your PSUs is not part of your normal or expected compensation for purposes of calculating any severance, retirement, welfare, insurance or similar employee benefit.

5

Shareholder Rights	You do not have any of the rights of a shareholder with respect to the PSUs unless and until the Shares relating to the vested PSUs are paid to you.  You do not have the right to make an election pursuant to Section 83(b) of the Internal Revenue Code of 1986, as amended.
Adjustments	In the event of a split, a dividend or a similar change in the Shares, the number of Shares covered by this grant may be adjusted (and rounded down to the nearest whole number) pursuant to the Plan. Your Shares shall be subject to the terms of the agreement of merger, liquidation or reorganization in the event the Company is subject to such corporate activity.
Successors and Assigns	The Company may assign any of its rights under this Agreement. This Agreement will be binding upon and inure to the benefit of the successors and assigns of the Company. Subject to the restrictions on transfer set forth herein, this Agreement will be binding upon you and your beneficiaries, executors, administrators and the person(s) to whom the PSUs may be transferred by will or the laws of descent or distribution.
The Plan	The Plan is discretionary and may be amended, cancelled or terminated by the Company at any time, in its discretion. The grant of the PSUs in this Agreement does not create any contractual right or other right to receive any PSUs or other grants in the future. Future grants, if any, will be at the sole discretion of the Company. Any amendment, modification, or termination of the Plan shall not constitute a change or impairment of the terms and conditions of your service with the Company.
	The text of the Plan is incorporated in this Agreement by reference. Except as otherwise noted, capitalized terms used in this Agreement, and not otherwise defined in this Agreement, have the meaning set forth in the Plan.
	This Agreement and the Plan constitute the entire understanding between you and the Company regarding the award of PSUs under this Agreement. Any prior agreements, commitments or negotiations concerning the award of PSUs under this Agreement are superseded.
