(a) Payment of Distributions. Subject to the preferential rights of holders of any class or series of Partnership Interests of the Partnership now or hereafter issued and outstanding, ranking senior to the Series A-1 Preferred Units with respect to the payment of distributions, holders of the Series A-1 Preferred Units shall be entitled to receive, when, as and if authorized by the General

- 4 -

Partner out of funds legally available for payment of distributions, cumulative cash distributions in an amount equal to the Series A-1 Priority Return. Such distributions shall accrue and be cumulative from and including the first date on which any Series A-1 Preferred Units are issued or, if later, the most recent Series A-1 Distribution Payment Date to which distributions have been paid in full, and shall be payable quarterly in arrears, on each Series A-1 Preferred Unit Distribution Payment Date; provided, however, if any Series A-1 Preferred Unit Distribution Payment Date is not a Business Day, then the distribution which would otherwise have been payable on such Series A-1 Preferred Unit Distribution Payment Date may be paid, at the General Partner’s option, on either the immediately preceding Business Day or the next succeeding Business Day, except that, if such Business Day is in the next succeeding calendar year, such payment shall be made on the immediately preceding Business Day, in each case with the same force and effect as if paid on such Series A-1 Preferred Unit Distribution Payment Date, and no interest or additional distributions or other sums shall accrue on the amount so payable from such Series A-1 Preferred Unit Distribution Payment Date to such next succeeding Business Day. The amount of any distribution payable on the Series A-1 Preferred Units for any period greater or less than a full Series A-1 Distribution Period shall be prorated and computed on the basis of a 360-day year consisting of twelve 30-day months. Distributions will be payable to holders of record as they appear in the records of the General Partner at the close of business on the applicable Series A-1 Distribution Record Date. Notwithstanding any provision to the contrary contained herein, each holder of an outstanding Series A-1 Preferred Unit shall be entitled to receive a distribution with respect to any Series A-1 Distribution Record Date equal to the distribution paid with respect to each other Series A-1 Preferred Unit that is outstanding on such date, and to the extent a holder of outstanding Series A-1 Preferred Units redeems such units before a Series A-1 Distribution Date, such holder will not be entitled to any future distributions on his, her, or its Series A-1 Preferred Units.

(b) Distributions Cumulative. Notwithstanding anything contained herein to the contrary, distributions on the Series A-1 Preferred Units shall accrue whether or not the terms and provisions set forth in Section 3(c) at any time prohibit the current payment of distributions, whether or not the Partnership has earnings, whether or not there are funds legally available for the payment of such distributions and whether or not such distributions are authorized or declared.

(c)     Priority as to Distributions.

(i)     Except as provided in Sections 3(c)(ii) and 3(e) below, no distributions shall be declared and paid or declared and set apart for payment, and no other distribution of cash or other property may be declared and made, directly or indirectly, on or with respect to any Parity Preferred Unit or Junior Unit as to distributions for any period, nor shall any Junior Units or Parity Preferred Units as to distributions and the distribution of assets upon the Partnership’s liquidation, dissolution or winding up be redeemed, purchased or otherwise acquired for any consideration, nor shall any funds be paid or made available for a sinking fund for the redemption of such units, and no other distribution of cash or other property may be made, directly or indirectly, on or with respect thereto by the Partnership, unless full cumulative distributions on the Series A-1 Preferred Units for all past Series A-1 Distribution Periods shall have been or contemporaneously are (i) declared and paid or (ii) declared and a sum sufficient for the payment thereof is set apart for such payment.

- 5 -

(ii)     Except as provided in Section 3(e) below, when distributions are not paid in full (or declared and a sum sufficient for such full payment is not so set apart) upon the Series A-1 Preferred Units and any other Parity Preferred Units as to distributions, all distributions declared upon the Series A-1 Preferred Units and such other classes or series of Parity Preferred Units as to the payment of distributions shall be declared pro rata so that the amount of distributions declared per Series A-1 Preferred Unit and each Parity Preferred Unit of such other class or series shall in all cases bear to each other the same ratio that accrued distributions per Series A-1 Preferred Unit and per Parity Preferred Unit of such other class or series (which shall not include any accrual in respect of unpaid distributions on such other class or series of Parity Preferred Units for prior Series A-1 Distribution Periods if such other class or series of Parity Preferred Unit does not have a cumulative distribution) bear to each other. No interest, or sum of money in lieu of interest, shall be payable in respect of any distribution payment or payments on the Series A-1 Preferred Units which may be in arrears.

(d)     Holders of the Series A-1 Preferred Units shall not be entitled to any distributions, whether payable in cash, other property or otherwise, in excess of the full cumulative distributions on the Series A-1 Preferred Units as provided herein. Any distribution payment made on the Series A-1 Preferred Units shall first be credited against the earliest accrued but unpaid distributions due with respect to such Series A-1 Preferred Units which remain payable. Accrued but unpaid distributions on the Series A-1 Preferred Units will accrue as of the Series A-1 Preferred Unit Distribution Payment Date on which they first become payable.

(e)     Notwithstanding the provisions of Section 3(c) and regardless of whether distributions are paid in full (or declared and a sum sufficient for such full payment is not so set apart) on the Series A-1 Preferred Units or Parity Preferred Units, as to distributions, for any or all Distribution Periods, the Partnership shall not be prohibited or limited from (i) paying distributions on any Partnership Units in Junior Units as to payment of distributions and the distribution of assets upon the Partnership’s liquidation, dissolution and winding up, (ii) converting or exchanging any Partnership Units for Junior Units as to payment of distributions and the distribution of assets upon the Partnership’s liquidation, dissolution and winding up, (iii) taking necessary action to ensure that the General Partner remains qualified as a REIT, or (iv) redeeming Series A-1 Preferred Units pursuant to Section 5 or Section 10 below.

Section 4.     Liquidation Proceeds.

(a)     Distributions. Upon any voluntary or involuntary liquidation, dissolution or winding-up of the Partnership, subject to the preferential rights of holders of any class or series of Partnership Interests of the Partnership now or hereafter issued and outstanding, ranking senior to the Series A-1 Preferred Units with respect to liquidating distributions, and taking into account the rights of holders of any Parity Preferred Units then outstanding, a holder of the Series A-1 Preferred Units shall first be entitled to receive the Stated Value per Series A-1 Preferred Unit, plus any accrued and unpaid Series A-1 Priority Return, and then distributions shall be made in accordance with Article 13 of the Partnership Agreement.

(b)     Notice. Written notice of any such voluntary or involuntary liquidation, dissolution or winding-up of the Partnership, stating the payment date or dates when, and the place

- 6 -

or places where, the amounts distributable in such circumstances shall be payable, shall be given by the General Partner pursuant to Section 13.5 of the Partnership Agreement.

(c)     No Further Rights. After payment of the full amount of the liquidating distributions to which it is entitled, a holder of the Series A-1 Preferred Units will have no right or claim to any of the remaining assets of the Partnership.

(d)     Consolidation, Merger or Certain Other Transactions. The voluntary sale, conveyance, lease, exchange or transfer (for cash, shares, securities or other consideration) of all or substantially all of the property or assets of the Partnership to, or the consolidation or merger or other business combination of the Partnership with or into or conversion into, any other corporation, trust or other entity (or of any corporation, trust or other entity with or into the Partnership) shall not be deemed to constitute a liquidation, dissolution or winding-up of the Partnership.

Section 5.     General PartnerRedemption.

(a) Optional Redemption.

i. Except as provided in Section 5(b) herein or upon a determination of the General Partner's board of trustees that such redemption is reasonably necessary to preserve the General Partner's status as a REIT, Series A-1 Preferred Units shall not be redeemable prior to the date that is ten years after the date of initial issuance of each Series A-1 Preferred Unit (the "Non-Call Period").

ii. On and after the Non-Call Period, the General Partner, at its option, upon notice in accordance with Section 5(a)(iv), may redeem the Series A-1 Preferred Units, in whole or in part, at any time or from time to time, for cash at a redemption price equal to the Stated Value per unit, plus, subject to Section 5(a)(v), all accrued and unpaid distributions (whether or not authorized or declared) thereon up to but excluding the date fixed for redemption, without interest, to the extent the General Partner has funds legally available therefor (the "Optional Redemption Right"). If fewer than all of the outstanding Series A-1 Preferred Units are to be redeemed pursuant to this Section 5(a)(ii), the Series A-1 Preferred Units to be redeemed shall be redeemed pro rata (as nearly as may be practicable without creating fractional units) or by lot as determined by the General Partner. Holders of Series A-1 Preferred Units to be redeemed shall surrender such Series A-1 Preferred Units at the place, or in accordance with the book-entry procedures, designated in such notice and shall be entitled to the redemption price equal to the Stated Value per unit and any accrued and unpaid distributions payable upon such redemption following such surrender. If (i) notice of redemption of any Series A-1 Preferred Units has been given, (ii) the funds necessary for such redemption have been set aside by the General Partner for the benefit of the holders of any Series A-1 Preferred Units so called for redemption,

- 7 -

and (iii) irrevocable instructions have been given to pay the redemption price and all accrued and unpaid distributions, then from and after the redemption date, distributions shall cease to accrue on such Series A-1 Preferred Units, such Series A-1 Preferred Units shall no longer be deemed outstanding, and all rights of the holders of such units shall terminate, except the right to receive the redemption price plus any accrued and unpaid distributions payable upon such redemption, without interest. So long as full cumulative distributions on the Series A-1 Preferred Units for all past Series A-1 Distribution Periods shall have been or contemporaneously are (i) declared and paid, or (ii) declared and a sum sufficient for the payment thereof is set apart for payment, nothing herein shall prevent or restrict the General Partner's right or ability to purchase, from time to time, either at a public or a private sale, all or any part of the Series A-1 Preferred Units at such price or prices as the General Partner may determine, subject to the provisions of applicable law, including the repurchase of Series A-1 Preferred Units in open-market transactions or individual purchases duly authorized by the General Partner.

iii. Except as provided in Section 3(e) above, unless full cumulative distributions on the Series A-1 Preferred Units for all past Series A-1 Distribution Periods shall have been or contemporaneously are (i) declared and paid in cash or (ii) declared and a sum sufficient for the payment thereof in cash is set apart for payment, no Series A-1 Preferred Units shall be redeemed pursuant to the Optional Redemption Right or Special Optional Redemption Right unless all outstanding Series A-1 Preferred Units are simultaneously redeemed, and the General Partner shall not purchase or otherwise acquire directly or indirectly any Series A-1 Preferred Units or any class or series of units of the General Partner ranking, as to payment of distributions and the distribution of assets upon liquidation, dissolution or winding up of the General Partner, on parity with or junior to the Series A-1 Preferred Units.

iv. Notice of redemption pursuant to the Optional Redemption Right will be mailed by the General Partner, postage prepaid, not fewer than 30 or more than 60 days prior to the redemption date, addressed to the respective holders of record of the Series A-1 Preferred Units to be redeemed at their respective addresses as they appear on the unit transfer records of the General Partner. No failure to give or defect in such notice shall affect the validity of the proceedings for the redemption of any Series A-1 Preferred Units except as to the holder to whom such notice was defective or not given. In addition to any information required by law, each such notice shall state: (i) the redemption date; (ii) the redemption price; (iii) the number of Series A-1 Preferred Units to be redeemed; (iv) the place or places where the certificates, if any, representing Series A-1 Preferred

- 8 -

Units are to be surrendered for payment of the redemption price; (v) procedures for surrendering uncertificated Series A-1 Preferred Units for payment of the redemption price; (vi) that distributions on the Series A-1 Preferred Units to be redeemed will cease to accrue on such redemption date; and (vii) that payment of the redemption price and any accumulated and unpaid distributions will be made upon presentation and surrender of such Series A-1 Preferred Units. If fewer than all of the Series A-1 Preferred Units held by any holder are to be redeemed, the notice mailed to such holder shall also specify the number of Series A-1 Preferred Units held by such holder to be redeemed. Notwithstanding the foregoing, the General Partner is not required to provide such notice in the event the General Partner redeems the Series A-1 Preferred Units in order to maintain the General Partner's status as a REIT.

v. If a redemption date falls after a Series A-1 Distribution Record Date and on or prior to the corresponding Series A-1 Distribution Payment Date, each holder of Series A-1 Preferred Units at the close of business on such Series A-1 Distribution Record Date shall be entitled to the distribution payable on such units on the corresponding Series A-1 Distribution Payment Date notwithstanding the redemption of such units on or prior to such Series A-1 Distribution Payment Date, and each holder of Series A-1 Preferred Units that surrenders its units on such redemption date will be entitled to the distributions accruing after the end of the Series A-1 Distribution Period to which such Series A-1 Distribution Payment Date relates up to but excluding the redemption date. Except as provided herein, the General Partner shall make no payment or allowance for unpaid distributions, whether or not in arrears, on Series A-1 Preferred Units for which a notice of redemption has been given.

vi. All the Series A-1 Preferred Units redeemed or repurchased pursuant to this Section 5(a), or otherwise acquired in any other manner by the General Partner, shall be restored to the status of authorized but unissued Preferred Units, without designation as to series or class.

(b) Special Optional Redemption.

i. Upon a Change of Control of the General Partner, the General Partner may, upon written notice mailed by the General Partner, postage pre-paid, no fewer than 30 nor more than 60 days prior to the redemption date and addressed to the holders of record of the Series A-1 Preferred Units to be redeemed at their respective addresses as they appear on the unit transfer records of the General Partner, redeem the Series A-1 Preferred Units, in whole or in part, within 120 days after the first date on which such Change of Control occurred, for cash at the Stated Value per unit plus, subject to Section 5(b)(iv), accrued and unpaid distributions,

- 9 -

if any, to, but not including, the redemption date ("Special Optional Redemption Right"). No failure to give such notice or any defect thereto or in the mailing thereof shall affect the validity of the proceedings for the redemption of any Series A-1 Preferred Units except as to the holder to whom notice was defective or not given.

ii. In addition to any information required by law, such notice shall state: (i) the redemption date; (ii) the redemption price; (iii) the number of Series A-1 Preferred Units to be redeemed; (iv) the place or places where the certificates, if any, representing Series A-1 Preferred Units are to be surrendered for payment of the redemption price; (v) procedures for surrendering uncertificated Series A-1 Preferred Units for payment of the redemption price; (vi) that distributions on the Series A-1 Preferred Units to be redeemed will cease to accrue on the redemption date; (vii) that payment of the redemption price and any accumulated and unpaid distributions will be made upon presentation and surrender of such Series A-1 Preferred Units; and (viii) that the Series A-1 Preferred Units are being redeemed pursuant to the Special Optional Redemption Right in connection with the occurrence of a Change of Control and a brief description of the transaction or transactions constituting such Change of Control. If fewer than all of the Series A-1 Preferred Units held by any holder are to be redeemed, the notice mailed to such holder shall also specify the number of Series A-1 Preferred Units held by such holder to be redeemed. Holders of Series A-1 Preferred Units to be redeemed shall surrender such Series A-1 Preferred Units at the place, or in accordance with the book-entry procedures, designated in such notice and shall be entitled to the redemption price equal to the Stated Value per unit and any accrued and unpaid distributions payable upon such redemption following such surrender.

If fewer than all of the outstanding Series A-1 Preferred Units are to be redeemed pursuant to the Special Optional Redemption Right, the Series A-1 Preferred Units to be redeemed shall be redeemed pro rata (as nearly as may be practicable without creating fractional units) or by lot as determined by the General Partner.

iii. If (i) the General Partner has given a notice of redemption pursuant to the Special Optional Redemption Right, (ii) the funds necessary for such redemption have been set aside by the General Partner for the benefit of the holders of the Series A-1 Preferred Units so called for redemption, and (iii) irrevocable instructions have been given to pay the redemption price and all accrued and unpaid distributions, then from and after the redemption date, distributions shall cease to accrue on such Series A-1 Preferred Units, such Series A-1 Preferred Units shall no longer be deemed outstanding, and all rights of the holders of such units shall

- 10 -

terminate, except the right to receive the redemption price plus any accrued and unpaid distributions payable upon such redemption, without interest. So long as full cumulative distributions on the Series A-1 Preferred Units for all past Series A-1 Distribution Periods shall have been or contemporaneously are (i) declared and paid or (ii) declared and a sum sufficient for the payment thereof is set apart for payment, nothing herein shall prevent or restrict the General Partner's right or ability to purchase, from time to time, either at a public or a private sale duly authorized by the General Partner's board of trustees, all or any part of the Series A-1 Preferred Units at such price or prices as the General Partner may determine, subject to the provisions of applicable law, including the repurchase of Series A-1 Preferred Units in open-market transactions or individual purchases duly authorized by the General Partner's board of trustees.

iv. If a redemption date falls after a Series A-1 Distribution Record Date and on or prior to the corresponding Series A-1 Distribution Payment Date, each holder of Series A-1 Preferred Units at the close of business of such Series A-1 Distribution Record Date shall be entitled to the distribution payable on such units on the corresponding Series A-1 Distribution Payment Date notwithstanding the redemption of such units on or prior to such Series A-1 Distribution Payment Date, and each holder of Series A-1 Preferred Units that surrenders its units on such redemption date will be entitled to the distributions accruing after the end of the Series A-1 Distribution Period to which such Series A-1 Distribution Payment Date relates up to but excluding the redemption date. Except as provided herein, the General Partner shall make no payment or allowance for unpaid distributions, whether or not in arrears, on Series A-1 Preferred Units for which a notice of redemption has been given.

Section 6.     Rank. The Series A-1 Preferred Units will, with respect to distribution rights and rights upon voluntary or involuntary liquidation, dissolution or winding-up of the Partnership, rank (a) senior to the OP Units, LTIP Units, and all other Partnership Units, the terms of which provide that such Partnership Units shall rank junior to the Series A-1 Preferred Units as to distributions and rights upon voluntary or involuntary liquidation, dissolution or winding-up of the Partnership; (b) on parity with all Parity Preferred Units, including Third Party Parity Preferred Units; and (c) junior to all Partnership Units, the terms of which provide that such Partnership Units shall rank senior to the Series A-1 Preferred Units as to distributions and rights upon voluntary or involuntary liquidation, winding-up or dissolution of the Partnership ("Senior Units"). The Series A-1 Preferred Units will also rank junior in right of payment to the Partnership's existing and future debt obligations.

Section 7.     Voting Rights. Holders of Series A-1 Preferred Units shall not have any voting or consent rights in respect of their partnership interests represented by the Series A-1 Preferred Units, except that (i) the affirmative vote of a majority in interest of the holders of Series A-1 Preferred Units, voting together as a single class with the holders of Third Party Parity Preferred Units (if any

- 11 -

are issued and outstanding), will be required for any amendments to the terms of the Series A-1 Preferred Units and the Third Party Parity Preferred Units (if any) that materially and adversely affect the rights, preferences, privileges or voting powers of the Series A-1 Preferred Units and the Third Party Parity Preferred Units similarly and (ii) the affirmative vote of the Series A-1 Preferred Units, voting as a separate class, will be required with respect to any amendment that materially and adversely affects the rights, preferences, privileges or voting powers of the Series A-1 Preferred Units disproportionately relative to any Third Party Parity Preferred Units. Notwithstanding the foregoing, the General Partner is entitled to issue additional securities in the Operating Partnership, including but not limited to Junior Units, Parity Preferred Units and Senior Units and exercise its redemption rights, in its sole and absolute discretion, without the approval or vote of any Series A-1 Preferred Unit or Third Party Parity Preferred Unit.

Section 8.    Transfer Restrictions. The Series A-1 Preferred Units shall not be transferable except in accordance with Article XI of the Partnership Agreement.

Section 9.     No Sinking Fund. No sinking fund shall be established for the retirement or redemption of Series A-1 Preferred Units.

Section 10.    Holder Redemption.

(a)    On or after the first anniversary of the date of issuance of each Series A-1 Preferred Unit, each holder of Series A-1 Preferred Units shall have the right (subject to the terms and conditions set forth herein and in any other such agreement between such holder and the Partnership, as applicable) to require the Partnership to redeem (a “Holder Redemption”) all or a portion of the Series A-1 Preferred Units held by such Partner (such Series A-1 Preferred Units being hereafter referred to as “Tendered Units”) in exchange for a cash amount per Series A-1 Preferred Unit equal to the Cash Amount unless the terms of such Series A-1 Preferred Units or a separate agreement entered into between the Partnership and the holder of such Series A-1 Preferred Units provides that such Series A-1 Preferred Units are not entitled to a right of Holder Redemption. The Tendering Partner (as defined below) shall have no right, with respect to any Series A-1 Preferred Units so redeemed, to receive any distributions paid on or after the date of delivery of the Cash Amount or the REIT Series A Preferred Shares, as the case may be. Any Holder Redemption shall be exercised pursuant to a Notice of Redemption delivered to the General Partner by the holder of Series A-1 Preferred Units who is exercising the redemption right (the “Tendering Partner”). The Cash Amount shall be payable to the Tendering Partner on the Specified Redemption Date.

(b)    Notwithstanding Section 10(a) above, if a holder of Series A-1 Preferred Units has delivered to the General Partner a Series A-1 Notice of Redemption, then the General Partner may, in its sole and absolute discretion, (subject to the limitations on ownership and transfer of REIT Series A Preferred Shares set forth in its Organizational Documents) elect to assume and satisfy the Partnership’s Holder Redemption obligation and acquire some or all of the Tendered Series A-1 Units from the Tendering Series A-1 Partner in exchange for the delivery by the General Partner to the Tendering Series A-1 Partner of the REIT Series A Preferred Share Amount (as of the Specified Redemption Date) and, if the General Partner so elects, the Tendering Series A-1 Partner shall sell the Tendered Series A-1 Units to the General Partner in exchange for the REIT Series A Preferred Share Amount. In such event, the Tendering Series A-1 Partner shall have no right to cause the

- 12 -

Partnership to redeem such Tendered Series A-1 Units. The General Partner shall give such Tendering Series A-1 Partner written notice of its election on or before the close of business on the fifth Business Day after the its receipt of the Series A-1 Notice of Redemption, and the Tendering Series A-1 Partner may elect to withdraw its redemption request at any time prior to the acceptance of the Cash Amount or REIT Series A Preferred Share Amount by such Tendering Series A-1 Partner. Assuming the General Partner exercises its option to deliver REIT Series A Preferred Shares, the General Partner shall retain the Tendered Series A-1 Units. Holders of Series A-1 Preferred Units will not be permitted to be a record holder of both Series A Preferred Shares and Series A-1 Preferred Units on the same record date.

(c)    The REIT Series A Preferred Share Amount, if applicable, shall be delivered as duly authorized, validly issued, fully paid and nonassessable REIT Series A Preferred Shares and, if applicable, free of any pledge, lien, encumbrance or transfer restriction, other than those provided in the General Partner’s Organizational Documents, the Securities Act, relevant state securities or blue sky laws and any applicable registration rights agreement or lock-up agreement with respect to such REIT Series A Preferred Shares entered into by the Tendering Series A-1 Partner. In addition, the REIT Series A Preferred Shares for which the Partnership Units might be exchanged shall also bear a legend which generally provides the following (or such other legend that may be specified in the General Partner's Organizational Documents):

THE SHARES EVIDENCED BY THIS CERTIFICATE ARE SUBJECT TO RESTRICTIONS ON BENEFICIAL OWNERSHIP AND CONSTRUCTIVE OWNERSHIP AND TRANSFER FOR THE PURPOSE, AMONG OTHERS, OF THE MAINTENANCE BY NATIONAL STORAGE AFFILIATE TRUST (THE “TRUST”) OF ITS QUALIFICATION AS A REAL ESTATE INVESTMENT TRUST UNDER THE INTERNAL REVENUE CODE OF 1986, AS AMENDED (THE “CODE”). SUBJECT TO CERTAIN FURTHER RESTRICTIONS AND EXCEPT AS EXPRESSLY PROVIDED IN THE TRUST'S DECLARATION OF TRUST, (I) NO PERSON MAY BENEFICIALLY OWN OR CONSTRUCTIVELY OWN COMMON SHARES IN EXCESS OF 9.8 PERCENT (IN VALUE OR NUMBER OF SHARES, WHICHEVER IS MORE RESTRICTIVE) OF THE OUTSTANDING COMMON SHARES UNLESS SUCH PERSON IS EXEMPT FROM SUCH LIMITATION OR IS AN EXCEPTED HOLDER (IN WHICH CASE THE EXCEPTED HOLDER LIMIT SHALL BE APPLICABLE); (II) NO PERSON MAY BENEFICIALLY OWN OR CONSTRUCTIVELY OWN PREFERRED SHARES OF ANY CLASS OR SERIES IN EXCESS OF 9.8 PERCENT (IN VALUE OR NUMBER OF SHARES, WHICHEVER IS MORE RESTRICTIVE) OF THE OUTSTANDING PREFERRED SHARES OF SUCH CLASS OR SERIES, UNLESS SUCH PERSON IS EXEMPT FROM SUCH LIMITATION OR IS AN EXCEPTED HOLDER (IN WHICH CASE THE EXCEPTED HOLDER LIMIT SHALL BE APPLICABLE); (III) NO PERSON MAY BENEFICIALLY OWN OR CONSTRUCTIVELY OWN EQUITY SHARES IN EXCESS OF 9.8 PERCENT (IN VALUE OR NUMBER OF SHARES, WHICHEVER IS MORE RESTRICTIVE) OF THE TOTAL OUTSTANDING EQUITY SHARES, UNLESS SUCH PERSON IS EXEMPT FROM SUCH LIMITATION OR IS AN EXCEPTED HOLDER (IN WHICH CASE THE EXCEPTED HOLDER LIMIT SHALL BE APPLICABLE); (IV) NO PERSON MAY BENEFICIALLY OWN OR CONSTRUCTIVELY OWN EQUITY SHARES THAT WOULD RESULT IN THE TRUST BEING “CLOSELY HELD” UNDER SECTION 856(H) OF THE CODE (WITHOUT REGARD

- 13 -

TO WHETHER THE OWNERSHIP INTEREST IS HELD DURING THE LAST HALF OF A TAXABLE YEAR) OR OTHERWISE CAUSE THE TRUST TO FAIL TO QUALIFY AS A REIT; AND (V) ANY TRANSFER OF EQUITY SHARES THAT, IF EFFECTIVE, WOULD RESULT IN THE EQUITY SHARES BEING BENEFICIALLY OWNED BY LESS THAN 100 PERSONS (AS DETERMINED UNDER THE PRINCIPLES OF SECTION 856(A)(5) OF THE CODE) SHALL BE VOID AB INITIO, AND THE INTENDED TRANSFEREE SHALL ACQUIRE NO RIGHTS IN SUCH EQUITY SHARES. ANY PERSON WHO BENEFICIALLY OWNS OR CONSTRUCTIVELY OWNS OR ATTEMPTS TO BENEFICIALLY OWN OR CONSTRUCTIVELY OWN EQUITY SHARES WHICH CAUSES OR WILL CAUSE A PERSON TO BENEFICIALLY OWN OR CONSTRUCTIVELY OWN EQUITY SHARES IN EXCESS OR IN VIOLATION OF THE ABOVE LIMITATIONS MUST IMMEDIATELY NOTIFY THE TRUST OR, IN THE CASE OF SUCH A PROPOSED OR ATTEMPTED TRANSACTION, GIVE AT LEAST 15 DAYS PRIOR WRITTEN NOTICE. IF ANY OF THE RESTRICTIONS ON TRANSFER OR OWNERSHIP AS SET FORTH IN (I), (II), (III) OR (IV) ABOVE ARE VIOLATED, THE EQUITY SHARES IN EXCESS OR IN VIOLATION OF THE ABOVE LIMITATIONS WILL BE TRANSFERRED AUTOMATICALLY TO A TRUSTEE OF A CHARITABLE TRUST FOR THE BENEFIT OF ONE OR MORE CHARITABLE BENEFICIARIES. FURTHERMORE, UPON THE OCCURRENCE OF CERTAIN EVENTS, ATTEMPTED TRANSFERS IN VIOLATION OF THE RESTRICTIONS DESCRIBED ABOVE MAY BE VOID AB INITIO. ALL CAPITALIZED TERMS IN THIS LEGEND HAVE THE MEANINGS DEFINED IN THE TRUST’S DECLARATION OF TRUST, AS THE SAME MAY BE AMENDED FROM TIME TO TIME, A COPY OF WHICH, INCLUDING THE RESTRICTIONS ON TRANSFER AND OWNERSHIP, WILL BE FURNISHED TO EACH HOLDER OF EQUITY SHARES ON REQUEST AND WITHOUT CHARGE. REQUESTS FOR SUCH A COPY MAY BE DIRECTED TO THE SECRETARY OF THE TRUST AT ITS PRINCIPAL OFFICE.

(d)    Each Tendering Series A-1 Partner covenants and agrees with the General Partner that all Tendered Series A-1 Units shall be delivered to the General Partner free and clear of all liens, claims and encumbrances whatsoever and should any such liens, claims and/or encumbrances exist or arise with respect to such Tendered Series A-1 Units, the General Partner shall be under no obligation to acquire the same. Each Tendering Series A-1 Partner further agrees that, in the event any state or local property transfer tax is payable as a result of the transfer of its Tendered Series A-1 Units to the General Partner (or its designee), such Tendering Series A-1 Partner shall assume and pay such transfer tax.

(e)    Notwithstanding any other provision of this Agreement, a holder of Series A-1 Preferred Units (i) shall not be entitled to effect a Holder Redemption, whether for cash or an exchange for REIT Series A Preferred Shares to the extent the General Partner would not be able to deliver REIT Series A Preferred Shares to satisfy such Holder Redemption because the receipt and ownership of REIT Series A Preferred Shares pursuant to such exchange by such Partner on the Specified Redemption Date could cause such Partner or any other Person to violate the Ownership Limit set forth in the General Partner's Organizational Documents and (ii) shall have no rights under this Agreement to acquire REIT Series A Preferred Shares which would otherwise be prohibited under the General Partner’s Organizational Documents. To the extent any attempted Holder

- 14 -

Redemption or exchange for REIT Series A Preferred Shares would be in violation of this Section 10(e), it shall be null and void ab initio and such holder of Series A-1 Preferred Units shall not acquire any rights or economic interest in the cash otherwise payable upon such Holder Redemption or the REIT Series A Preferred Shares otherwise issuable upon such exchange.
