6.3.1 Upon any purported Transfer or other event described in Section 6.2.2 of this Article VI that would result in a transfer of shares of Capital Stock to a

13

Trust, such Capital Stock shall be deemed to have been transferred to the Trustee in his capacity as trustee of a Trust for the exclusive benefit of one or more Charitable Beneficiaries.

6.3.3 The Trustee shall have all voting rights and rights to dividends or other distributions with respect to Capital Stock held in the Trust, which rights shall be exercised for the exclusive benefit of the Charitable Beneficiary. Any dividend or other distribution paid prior to the discovery by the Corporation that shares of Capital Stock have been transferred to the Trustee shall be paid to the Trustee upon demand, and any dividend or other distribution declared or authorized but unpaid with respect to such Capital Stock shall be paid when due to the Trustee. Any dividends or distributions so paid over to the Trustee shall be held in trust for the Charitable Beneficiary. The Purported Record Transferee and Purported Beneficial Transferee shall have no voting rights with respect to the Capital Stock held in the

14

Trust and, subject to Maryland law, effective as of the date the Capital Stock has been transferred to the Trustee, the Trustee shall have the authority (at the Trustee’s sole discretion) (i) to rescind as void any vote cast by a Purported Record Transferee with respect to such Capital Stock prior to the discovery by the Corporation that the Capital Stock has been transferred to the Trustee and (ii) to recast such vote in accordance with the desires of the Trustee acting for the benefit of the Charitable Beneficiary; provided, however, that if the Corporation has already taken irreversible corporate action, then the Trustee shall not have the authority to rescind and recast such vote. Notwithstanding the provisions of this Article VI, until the Corporation has received notification that the Capital Stock has been transferred into a Trust, the Corporation shall be entitled to rely on its share transfer and other stockholder records for purposes of preparing lists of stockholders entitled to vote at meetings, determining the validity and authority of proxies and otherwise conducting votes of stockholders.

6.3.4 Within 20 days of receiving notice from the Corporation that shares of Capital Stock have been transferred to the Trust, the Trustee of the Trust shall sell the shares of Capital Stock held in the Trust to a person, designated by the Trustee, whose ownership of the shares of Capital Stock will not violate the ownership limitations set forth in Section 6.2.1. Upon such sale, the interest of the Charitable Beneficiary in the shares of Capital Stock sold shall terminate and the Trustee shall distribute the net proceeds of the sale to the Purported Record Transferee and to the Charitable Beneficiary as provided in this Section 6.3.4. The Purported Record Transferee shall receive the lesser of (i) the price paid by the Purported Record Transferee for the shares of Capital Stock in the transaction that resulted in such transfer to the Trust (or, if the event which resulted in the transfer to the Trust did not involve a purchase of such shares of Capital Stock at Market Price, the Market Price of such shares of Capital Stock on the day of the event which resulted in the transfer of such shares of Capital Stock to the Trust)

15

and (ii) the price per share received by the Trustee (net of any commissions and other expenses of sale) from the sale or other disposition of the shares of Capital Stock held in the Trust. The Trustee may reduce the amount payable to the Purported Record Transferee by the amount of dividends and distributions which have been paid to the Purported Record Transferee and are owed by the Purported Record Transferee to the Trustee pursuant to Section 6.3.3 of this Article VI. Any net sales proceeds in excess of the amount payable to the Purported Record Transferee shall be immediately paid to the Charitable Beneficiary together with any dividends or other distributions thereon. If, prior to the discovery by the Corporation that shares of such Capital Stock have been transferred to the Trustee, such shares of Capital Stock are sold by a Purported Record Transferee then (x) such shares of Capital Stock shall be deemed to have been sold on behalf of the Trust and (y) to the extent that the Purported Record Transferee received an amount for such shares of Capital Stock that exceeds the amount that such Purported Record Transferee was entitled to receive pursuant to this Section 6.3.4, such excess shall be paid to the Trustee upon demand.

6.3.5 Capital Stock transferred to the Trustee shall be deemed to have been offered for sale to the Corporation, or its designee, at a price per share equal to the lesser of (i) the price paid by the Purported Record Transferee for the shares of Capital Stock in the transaction that resulted in such transfer to the Trust (or, if the event which resulted in the transfer to the Trust did not involve a purchase of such shares of Capital Stock at Market Price, the Market Price of such shares of Capital Stock on the day of the event which resulted in the transfer of such shares of Capital Stock to the Trust) and (ii) the Market Price on the date the Corporation, or its designee, accepts such offer. The Corporation may reduce the amount payable to the Purported Record Transferee by the amount of dividends and distributions which has been paid to the Purported Record Transferee and are owed by the Purported Record

16

Transferee to the Trustee pursuant to Section 6.3.3 of this Article VI. The Corporation will pay the amount of such reduction to the Trustee for the benefit of the Charitable Beneficiary. The Corporation shall have the right to accept such offer until the Trustee has sold the shares of Capital Stock held in the Trust pursuant to Section 6.3.4. Upon such a sale to the Corporation, the interest of the Charitable Beneficiary in the shares of Capital Stock sold shall terminate and the Trustee shall distribute the net proceeds of the sale to the Purported Record Transferee, and any dividends or other distributions held by Trustee with respect to such Capital Stock shall thereupon be paid to the Charitable Beneficiary.

6.3.6 By written notice to the Trustee, the Corporation shall designate one or more nonprofit organizations to be the Charitable Beneficiary of the interest in the Trust such that (i) the shares of Capital Stock held in the Trust would not violate the restrictions set forth in Section 6.2.1 in the hands of such Charitable Beneficiary and (ii) each Charitable Beneficiary is an organization described in Sections 170(b)(1)(A), 170(c)(2) and 501(c)(3) of the Code.

Section 6.4 Remedies For Breach. If the Board of Directors or a committee thereof or other designees if permitted by the MGCL shall at any time determine in good faith that a Transfer or other event has taken place in violation of Section 6.2 of this Article VI or that a Person intends to acquire, has attempted to acquire or may acquire beneficial ownership (determined without reference to any rules of attribution), Beneficial Ownership or Constructive Ownership of any shares of the Corporation in violation of Section 6.2 of this Article VI (whether or not such violation is intended), the Board of Directors or a committee thereof or other designees if permitted by the MGCL shall take such action as it deems or they deem advisable to refuse to give effect or to prevent such Transfer, including, but not limited to, causing the Corporation to redeem shares of Capital Stock, refusing to give effect to such

17

Transfer on the books of the Corporation or instituting proceedings to enjoin such Transfer or other event; provided, however, that any Transfers (or, in the case of events other than a Transfer, ownership or Constructive Ownership or Beneficial Ownership) in violation of Section 6.2.1 of this Article VI shall automatically result in the transfer to a Trust as described in Section 6.2.2 and any Transfer in violation of Section 6.2.3 shall, subject to Section 6.12, automatically be void ab initio irrespective of any action (or non-action) by the Board of Directors or a committee thereof.

Section 6.5 Notice of Restricted Transfer. Any Person who acquires or attempts or intends to acquire shares in violation of Section 6.2 of this Article VI, or any Person who is a Purported Beneficial Transferee such that an automatic transfer to a Trust results under Section 6.2.2 of this Article VI, shall immediately give written notice to the Corporation of such event or, in the case of such a proposed or attempted transaction, give at least 15 days prior written notice and shall provide to the Corporation such other information as the Corporation may request in order to determine the effect, if any, of such Transfer or attempted Transfer on the Corporation’s status as a REIT.

Section 6.6 Owners Required to Provide Information. From the Initial Date and prior to the Restriction Termination Date, each Person who is a beneficial owner or Beneficial Owner or Constructive Owner of shares of Capital Stock and each Person (including the stockholder of record) who is holding shares of Capital Stock for a beneficial owner or Beneficial Owner or Constructive Owner shall, on demand, provide to the Corporation a completed questionnaire containing the information regarding their ownership of such shares, as set forth in the regulations (as in effect from time to time) of the U.S. Department of Treasury under the Code. In addition, each Person who is a beneficial owner or Beneficial Owner or Constructive Owner of shares of Capital Stock and each Person (including the stockholder of

18

record) who is holding shares of Capital Stock for a beneficial owner or Beneficial Owner or Constructive Owner shall, on demand, be required to disclose to the Corporation in writing such information as the Corporation may request in order to determine the effect, if any, of such stockholder’s Beneficial Ownership and Constructive Ownership of shares of Capital Stock on the Corporation’s status as a REIT and to ensure compliance with the Aggregate Stock Ownership Limit, the Common Stock Ownership Limit, any other ownership limit or as otherwise permitted by the Board of Directors.

Section 6.7 Remedies Not Limited. Nothing contained in this Article VI (but subject to Section 6.12 of this Article VI) shall limit the authority of the Board of Directors to take such other action as it deems necessary or advisable to protect the Corporation and the interests of its stockholders by preservation of the Corporation’s status as a REIT.

Section 6.8 Ambiguity. In the case of an ambiguity in the application of any of the provisions of this Article VI, including any definition contained in Section 6.1, the Board of Directors shall have the power to determine the application of the provisions of this Article VI with respect to any situation based on the facts known to it (subject, however, to the provisions of Section 6.12 of this Article VI). In the event Article VI requires an action by the Board of Directors and the charter of the Corporation does not provide specific guidance with respect to such action, the Board of Directors shall have the power to determine the action to be taken so long as such action is not contrary to the provisions of Article VI. Absent a decision to the contrary by the Board of Directors (which the Board may make in its sole and absolute discretion), if a Person would have (but for the remedies set forth in Section 6.2.2) acquired Beneficial or Constructive Ownership of Common Stock in violation of Section 6.2.1, such remedies (as applicable) shall apply first to the shares of Capital Stock which, but for such remedies, would have been actually owned by such Person, and second to shares of Capital

19

Stock which, but for such remedies, would have been Beneficially Owned or Constructively Owned (but not actually owned) by such Person, pro rata among the Persons who actually own such shares of Capital Stock based upon the relative number of the shares of Capital Stock held by each such Person.

Section 6.9 Exceptions.

6.9.1 Subject to Section 6.2.1(c) of this Article VI, the Board of Directors, in its sole discretion, may exempt (prospectively or retroactively) a Person from the limitation on a Person Beneficially Owning shares of Capital Stock in excess of the Aggregate Stock Ownership Limit or Common Stock in excess of the Common Stock Ownership Limit, as set forth in Section 6.2.1(a) of this Article VI, if the Board determines that such exemption will not cause any Individual’s Beneficial Ownership of shares of Capital Stock to violate the Capital Stock Ownership Limit and that any such exemption will not cause the Corporation to fail to qualify as a REIT under the Code.

6.9.2 Subject to Section 6.2.1(c) of this Article VI, the Board of Directors, in its sole discretion, may exempt (prospectively or retroactively) a Person from the limitation on a Person Constructively Owning Capital Stock in excess of the Aggregate Stock Ownership Limit or Common Stock in excess of the Common Stock Ownership Limit, as set forth in Section 6.2.1(b) of this Article VI, if the Board determines that such Person does not and will not own, actually or Constructively, an interest in a tenant of the Corporation (or a tenant of any entity owned in whole or in part by the Corporation) that would cause the Corporation to own, actually or Constructively, more than a 9.8% interest (as set forth in Section 856(d)(2)(B) of the Code) in such tenant or that any such ownership would not cause the Corporation to fail to qualify as a REIT under the Code.

20

6.9.3 Subject to Section 6.2.1(c) and the remainder of this Section 6.9.3, the Board of Directors may from time to time increase the Aggregate Stock Ownership Limit and/or the Common Stock Ownership Limit for one or more Persons and decrease the Aggregate Stock Ownership Limit and/or the Common Stock Ownership Limit for all other Persons; provided, however, that the decreased Aggregate Stock Ownership Limit and/or the Common Stock Ownership Limit will not be effective for any Person whose percentage ownership in Capital Stock or Common Stock, as the case may be, is in excess of such decreased Aggregate Stock Ownership Limit and/or the Common Stock Ownership Limit until such time as such Person’s percentage of Capital Stock or Common Stock, as the case may be, equals or falls below the decreased Aggregate Stock Ownership Limit and/or the Common Stock Ownership Limit, but any further acquisition of Capital Stock or Common Stock, as the case may be, in excess of such percentage ownership of Capital Stock or Common Stock, as the case may be, will be in violation of the Aggregate Stock Ownership Limit and/or Common Stock Ownership Limit, and, provided further, that the new Aggregate Stock Ownership Limit and/or Common Stock Ownership Limit would not allow five or fewer Persons to Beneficially Own more than 49% in value of the outstanding Capital Stock.

6.9.4 In granting a person an exemption under Section 6.9.1 or 6.9.2 above, the Board of Directors may require such Person to make certain representations or undertakings or to agree that any violation or attempted violation of such representations or undertakings (or other action which is contrary to the restrictions contained in Section 6.2 of this Article VI) will result in such Capital Stock being transferred to a Trust in accordance with Section 6.2.2 of this Article VI. Prior to granting any exception pursuant to Section 6.9.1 or 6.9.2 of this Article VI, the Board of Directors may require a ruling from the IRS, or an opinion of counsel, in either case in form and substance satisfactory to the Board of Directors in its sole discretion, as it may deem necessary or advisable in order to determine or ensure the Corporation’s status as a REIT.
