The first to occur of (A) the date of Manager's proposed termination date pursuant to clause (i) above, and (B) the date on which any of the events set forth in clause (ii) above occurs, shall be referred to herein as the "Retirement Trigger Date". If a Retirement Trigger Date occurs, then:

(i)    within fifteen (15) days of the Retirement Trigger Date, each Manager Party (by the Operating Partnership on behalf of such Manager Party pursuant to the power of attorney set forth in Section 9.2 hereof), as applicable, and the Operating Partnership (or its designee) shall execute an assignment and assumption agreement in substantially the form attached hereto as Exhibit E, pursuant to which each such Manager Party shall assign their respective right, title and interest in and to (a) this Agreement, (b) each of the NSA Asset Management Agreements in effect as of the Retirement Trigger Date, and (c) all of such Manager Party's intellectual property then owned by or registered in the name of such Manager Party, including, without limitation, all trade names, and trademarks associated with such Manager Party, the Properties and/or the Deferred Management Properties; and

(ii)    within fifteen (15) days after the determination of the Retirement Fee in accordance with Section 6.1(b) and 6.1(c) below, the Operating Partnership shall pay to the Key Persons (or their respective designees), pro rata with their respective ownership interest in the Manager, an amount (the "Retirement Fee") equal to (x) the annual Normalized EBITDA of the Properties and the Deferred Management Properties (based on Manager's financial statements for the management of the Properties and the Deferred Management Properties for the applicable years) averaged over the eight (8) calendar quarters occurring immediately prior to the Retirement Trigger Date, as reasonably determined by the Operating Partnership (or if the Retirement Trigger Date occurs less than eight (8) calendar quarters following the later of (A) the Initial Public Offering and (B) the Initial Contribution Date, the annualized Normalized EBITDA of the Properties and the Deferred Management Properties (based on Manager's financial statements for the management of the Properties and the Deferred Management Properties for any applicable full calendar year (or any annualized partial calendar year) averaged over such annualized eight (8) calendar quarter period, as reasonably determined by the Operating Partnership), multiplied by (y) four (4).

(b)    Within thirty (30) days of the Retirement Trigger Date, the Operating Partnership shall provide the Manager Parties written notice setting forth its determination of the Retirement Fee and a reasonably detailed description of its calculation thereof. If Manager disagrees with the Operating Partnership's calculation of the Retirement Fee and the Operating Partnership and Manager are unable to reach an agreement as to the Retirement Fee within ten (10) days of the date of Operating Partnership's initial notice, then Manager shall independently make its own determination of the Retirement Fee within forty-five (45) days of the date of Operating Partnership's initial notice and submit such determination to the Operating Partnership. If Manager fails to timely object to the Operating Partnership's determination of the Retirement Fee in accordance with the preceding sentence, then the Operating Partnership's determination shall be deemed to be the Retirement Fee. If Manager has timely submitted its determination and the difference between the Operating Partnership's determination and Manager's determination does not exceed ten percent (10%) of the lower of such determinations, then the Retirement Fee shall be an amount equal to the average of both determinations. If the difference between the amounts of such determinations exceeds ten percent (10%) of the lower of such amounts, then the Operating Partnership and Manager shall jointly appoint a certified public accountant who is independent and unaffiliated with the Parties with at least ten (10) years of experience valuing businesses similar to the business of the Manager (an "Approved Accountant") within fifteen (15) days after the determinations have been exchanged by the Operating Partnership and Manager. If the Operating Partnership and Manager fail to appoint an Approved Accountant during such fifteen (15) day period, then either Party may request the American Arbitration Association or any successor organization thereto to appoint the Approved Accountant within fifteen (15) days after such request. If no such Approved Accountant shall have been appointed within such fifteen (15) day period, then the Operating Partnership and Manager may apply to any court having jurisdiction to have such appointment made by such court. The Approved Accountant shall, within ten (10) Business Days after receipt of the determinations of the Retirement Fee prepared by each of the Operating Partnership and Manager, be empowered only to select as the proper amount of the Retirement Fee whichever of the two determinations the Approved Accountant believes is the more accurate determination of the Retirement Fee. Without limiting the generality of the foregoing, in rendering its decision, the Approved Accountant shall not add to, subtract from or otherwise modify the provisions of this Agreement or the determinations provided by the Operating Partnership and Manager. The decision of the Approved Accountant shall be final and binding on the Parties. For the avoidance of doubt, in the event of a dispute pursuant to this Section 6.1(b), the non-prevailing Party shall reimburse the prevailing Party a reasonable sum for attorneys' fees actually incurred in connection with such dispute and the resolution thereof; provided, however, that the cost of the Approved Accountant shall be shared equally by the parties.

(c)    The Retirement Fee will be paid to Manager in Class A common units of limited partnership interest in the Operating Partnership ("Class A OP Units"). The number of Class A OP Units to which the Key Persons (or their respective designees) would be entitled pursuant to this Section 6.1(c) will be equal to (i) the Retirement Fee divided by (ii) the Value of a REIT Common Share as of the Retirement Trigger Date (rounded up to the next whole number of Class A OP Units in the event that the calculation of Class A OP Units equivalent to the Retirement Fee yields any fractional amount of Class A OP Units). Upon a Retirement Trigger Date, the Manager Parties and each of their respective Affiliates shall, subject to the terms and conditions set forth in the applicable Partnership Unit Designation, convert all of their Series SO Class B common units of limited partnership interest in the Operating Partnership ("Class B OP Units") into Class A OP Units in accordance with the Partnership Unit Designation relating to the Class B OP Units.

In addition, no less than forty-five (45) days prior to the scheduled payoff date for any outstanding indebtedness encumbering a Controlled Property, such Manager Party will deliver a written notice (a "Debt Maturity Notice") to the Operating Partnership, which Debt Maturity Notice shall indicate (i) the date of such scheduled payoff date, (ii) the weighted average monthly Economic Occupancy of such Controlled Property based on the twelve (12) month period prior to the date of the Debt Maturity Notice (or, if such Controlled Property has not been open for business during the twelve (12) month period prior to the date of the Debt Maturity Notice, for the longest number of months prior to the date of the Debt Maturity Notice for which such information is reasonably available), and (iii) the weighted average daily Physical Occupancy of such Controlled Property for the thirty (30) day period prior to the date of the Debt Maturity Notice. If the Operating Partnership determines that the applicable Controlled Properties have both Economic Occupancy and Physical Occupancy consistent with or exceeding local market levels for self-storage and/or mini-warehouse facilities for such periods, then the Operating Partnership shall so notify the applicable Manager Parties pursuant to a written notice in accordance with the provisions of Section 8.4(b) below.

(ii)    In addition, no less than forty-five (45) days after the end of each calendar year, such Manager Party will deliver a written notice (an "Occupancy Report") to the Operating Partnership with respect to any Controlled Property which is not encumbered by any outstanding indebtedness, which Occupancy Report shall indicate (i) the weighted average monthly Economic Occupancy of such Controlled Property based on the twelve (12) month period prior to the end of such calendar year (or, if such Controlled Property has not been open for business during the twelve (12) month period prior to the date of the Occupancy Report, for the longest number of months prior to the date of the Occupancy Report for which such information is reasonably available), and (ii) the weighted average daily Physical Occupancy of such Controlled Property for the thirty (30) day period prior to the date of the Occupancy Report. If the Operating Partnership determines that the applicable Controlled Properties have both Economic Occupancy and Physical Occupancy consistent with or exceeding local market levels for self-storage and/or mini-warehouse facilities for such periods, then the Operating Partnership shall so notify the applicable Manager Parties pursuant to a written notice in accordance with the provisions of Section 8.4(b) below.

(b)    Within five (5) days of receipt of a Controlled Property Notice, if and to the extent required pursuant to Section 8.4(a)(i) above, a Debt Maturity Notice, or, at the option of the Operating Partnership, any Occupancy Report, the Operating Partnership shall provide the Manager Parties with a written notice specifying (i) the Operating Partnership's determination of the value of the applicable

Controlled Property as determined in accordance with the Cap Rate Matrix (the "Controlled Property Purchase Price"), together with a reasonably detailed description of its calculation thereof, and (ii) the number of Class A OP Units and Class B OP Units determined by the Operating Partnership in its sole discretion to be of equivalent value to the equity component of such Controlled Property Purchase Price. If the Manager Parties disagree with the Operating Partnership's determination of the Controlled Property Purchase Price for the applicable Controlled Property, it shall so notify the Operating Partnership in writing within two (2) days of receipt of the Operating Partnership's initial notice. If the Operating Partnership and the Manager Parties are unable to reach an agreement as to the Controlled Property Purchase Price within five (5) days of the date of Operating Partnership's initial notice, then the Operating Partnership and the Manager Parties shall jointly appoint a certified real estate appraiser who is independent and unaffiliated with the Parties with at least ten (10) years of experience appraising commercial real estate similar to the applicable Controlled Property (an "Appraiser") to independently prepare its own determination of the purchase price for the applicable Controlled Property in accordance with the Cap Rate Matrix. If the Operating Partnership and the Manager Parties fail to appoint an Appraiser during such five (5) day period, then either such Party may request the American Arbitration Association or any successor organization thereto to appoint the Appraiser within ten (10) days after such request. If no such Appraiser shall have been appointed within such ten (10) day period, then the Operating Partnership and the Manager Parties may apply to any court having jurisdiction to have such appointment made by such court. The Appraiser shall, within ten (10) Business Days after being appointed in accordance with this Section 8.4(b), submit its determination of the purchase price for the applicable Controlled Property, which determination shall be prepared on the basis of a "one-off" sale of the Controlled Property in exchange for immediately available funds. If the Manager Parties timely object to the Operating Partnership's initial determination and the difference between the higher amount of the Operating Partnership's determination and the Appraiser's determination does not exceed two percent (2%) of the Operating Partnership's determination, then the Operating Partnership's determination shall be deemed to be the Controlled Property Purchase Price for the applicable Controlled Property. If the Manager Parties have timely objected to the Operating Partnership's initial determination and the difference between the Manager Parties' determination and the Appraiser's determination exceeds two percent (2%) of the Operating Partnership's determination, then the Appraiser's determination shall be deemed to be the Controlled Property Purchase Price for the applicable Controlled Property. For the avoidance of doubt, in the event of any dispute pursuant to this Section 8.4(b), the non-prevailing Party shall reimburse the prevailing Party a reasonable sum for attorneys' fees actually incurred in connection with such dispute and the resolution thereof; provided, however, that the cost of the Appraiser shall be shared equally by the parties.

(c)    At any time within thirty (30) days of the final determination of the Controlled Property Purchase Price in accordance with Section 8.4(b), the Operating Partnership (or its designee) shall have the option, in its sole and absolute discretion, to acquire such Controlled Property (or all of the applicable Manager Party's interest therein) for an amount equal to the applicable Controlled Property Purchase Price, as finally determined in accordance with Section 8.4(b). Such option shall be exercisable by written notice to each Manager Party during such thirty (30) day period, which written notice shall specify (i) the Controlled Property Purchase Price, as finally determined in accordance with Section 8.4(b) and (ii) the number of Class A OP Units and Class B OP Units to be issued in connection with the acquisition of the applicable Controlled Property. If the Operating Partnership fails to timely exercise such option, it shall have no further rights with respect to the applicable Controlled Property, and the Manager Parties shall be free to enter into any Controlled Property Transaction with respect to such Controlled Property, without further obligation to comply with the provisions of this Section 8.4 for the applicable Controlled Property.

8.5    Non-Controlled Properties. Promptly following the date on which any Manager Party becomes aware that holders of a Controlling interest in any Non-Controlled Property desire to enter into a voluntary sale, conveyance, assignment, grant of any options with respect to, or any other transfer or

disposition (directly or indirectly, and whether or not for consideration or of record) of any Non-Controlled Property or any legal or beneficial interest in any such Non-Controlled Property (but excluding any new mortgage financing or refinancing of a Non-Controlled Property) (any such transaction, a "Non-Controlled Property Transaction"), such Manager Party shall provide written notice thereof to the Operating Partnership, which notice shall specify the anticipated closing date (if known) of the applicable Non-Controlled Property Transaction. If, within thirty (30) days of receipt of such notice (but in any case, prior to the anticipated closing date set forth in the Manager Party's notice), the Operating Partnership provides written notice to each Manager Party of its desire to purchase the applicable Non-Controlled Property, the Manager Parties shall use commercially reasonable good faith efforts to facilitate an offer by the Operating Partnership to the holders of the Controlling interest in the applicable Non-Controlled Property to purchase such property or any interest therein, as the case may be.

8.6    Restrictions on Future Acquisitions by the Manager Parties. No Manager Party shall enter into any Purchase Contract pursuant to which such Manager Party shall agree to acquire an interest of any kind (whether directly or indirectly) in any self-storage and/or mini-warehouse facility or in any Person owning or holding an interest therein, without first offering such opportunity to the Operating Partnership on the same terms that such interest was offered to the applicable Manager Party. In the event that the Operating Partnership declines to purchase such interest or fails to respond to the applicable Manager Party within ten (10) Business Days following receipt of such offer, the Manager Party shall be free to enter into such Purchase Contract on the same terms offered to the Operating Partnership for the immediately succeeding ninety (90) day period.
