C. EXCESS SHARES. 1. OWNERSHIP IN TRUST. Upon any purported Transfer (whether or not such Transfer is the result of a transaction entered into through the facilities of the NYSE) that results in Excess Shares pursuant to subparagraph B(4)(c) of this Article IV, such Excess Shares shall be deemed to have been transferred to the Corporation, as Trustee of a Trust for the exclusive benefit of such Beneficiary or Beneficiaries to whom an interest in such Excess Shares may later be transferred pursuant to subparagraph C(6). Excess Shares so held in trust shall be issued and outstanding stock of the Corporation. The Purported Record Transferee shall have no rights in such Excess Shares except the right to designate a transferee of such Excess Shares upon the terms specified in subparagraph C(6) of this Article IV. The Purported Beneficial Transferee shall have no rights in such Excess Shares except as provided in subparagraph C(6). 2. SEPARATE CLASS. Excess Shares shall be a separate class of issued and outstanding stock of the Corporation. The rights, privileges and other attributes of Excess Shares shall be as provided in paragraphs C(3), C(4), C(5) and C(6) of this Article IV. 3. DIVIDEND RIGHTS. Excess Shares shall not be entitled to any dividends. Any dividend or distribution paid prior to the discovery by the Corporation that the shares of Common Stock have been converted into Excess Shares shall be repaid to the Corporation upon demand and shall not be held for the benefit of any Beneficiary of the Trust. 4. RIGHTS UPON LIQUIDATION. Subject to the preferential rights of the Preferred Stock, if any, as may be determined by the Board of Directors of the Corporation pursuant to paragraph D of this Article IV, in the event of any voluntary or involuntary liquidation, dissolution or winding up of, or any distribution of the assets of the Corporation, each holder of Excess Shares shall be entitled to receive, ratably with each other holder of Common Equity Stock, that portion of the assets of the Corporation available for distribution to its stockholders as the number of Excess Shares held by such holder bears to the total number of shares of Common Equity Stock then outstanding. The Corporation, as holder of the Excess Shares in trust, or if the Corporation shall have been dissolved, any trustee appointed by the Corporation prior to its dissolution, shall distribute ratably to the Beneficiaries of the Trust, when determined (or if not determined, or only partially determined, ratably to the other holders of Common Stock and Beneficiaries of the Trust who have been determined), any such assets received in respect of the Excess Shares in any liquidation, dissolution or winding up of, or any distribution of the assets of the Corporation. 5. VOTING RIGHTS. The holders of Excess Shares shall not be entitled to vote on any matters (except as required by law); PROVIDED, HOWEVER, that no corporate action authorized by the stockholders prior to the discovery that shares of Common Stock have been converted into Excess Shares shall be void or voidable as a result of the inclusion of the vote of holders of Excess Shares in approving a corporate action or in determining the presence of a quorum. 6. RESTRICTIONS ON TRANSFER; DESIGNATION OF BENEFICIARY. (a) Excess Shares shall not be transferable. The Purported Record Transferee may freely designate a Beneficiary of an interest in the Trust (representing the number of Excess Shares held by the Trust attributable to a purported Transfer that resulted in the Excess Shares), if (i) Excess Shares held in the Trust would not be Excess Shares in the hands of such Beneficiary and (ii) the Purported Beneficial Transferee does not receive a price for designating such Beneficiary that reflects a price per share for such Excess Shares that exceeds (x) the price per share such Purported Beneficial Transferee paid for the Common Stock in the purported Transfer that resulted in the Excess Shares, or (y) if the Transfer or other event that resulted in the Excess Shares was not a transaction in which the Purported Beneficial Transferee gave value for such Excess Shares, a price per share equal to the Market Price on the date of the purported Transfer or other event that resulted in the Excess Shares. Upon such transfer of an interest in the Trust, the corresponding Excess Shares in the Trust shall be automatically exchanged for an equal number of shares of Common Stock and such shares of Common Stock shall be transferred of record to the transferee of the interest in the Trust if such Common Stock would not be Excess Shares in the hands of such transferee. Prior to any transfer of any interest in the Trust, the Purported Record Transferee must give advance notice to the Corporation of the intended transfer and the Corporation must have waived in writing its purchase rights under subparagraph C(7) of this Article IV. (b) Notwithstanding the foregoing, if a Purported Beneficial Transferee receives a price for designating a Beneficiary of an interest in the Trust that exceeds the amounts allowable under subparagraph C(6)(a) of this Article IV, such Purported Beneficial Transferee shall pay, or cause such Beneficiary to pay, such excess to the Corporation and such payment shall be the only remedy for breach of such requirement. 7. PURCHASE RIGHT IN EXCESS SHARES. Excess Shares 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 per share in the transaction that created such Excess Shares (or, if the Transfer or other event that resulted in the Excess Shares was not a transaction in which the Purported Beneficial Transferee gave value for such Excess Shares, a price per share equal to the Market Price on the date of the purported Transfer or other event that resulted in the Excess Shares) and (ii) the Market Price on the date the Corporation, or its designee, accepts such offer. The Corporation shall have the right to accept such offer for a period of ninety days after the later of (i) the date of the Transfer which resulted in such Excess Shares and (ii) the date the Board of Directors determines in good faith that a Transfer resulted in Excess Shares has occurred, if the Corporation does not receive a notice of such Transfer pursuant to subparagraph B(4)(e) of this Article IV. The Corporation may appoint a special trustee of the trust established under subparagraph C(1) for the purpose of consummating the purchase of the Excess Shares by the Corporation and such payment shall be the only remedy for breach of such requirement. D. PREFERRED STOCK. The Board of Directors of the Corporation, by resolution, is hereby expressly vested with authority to provide for the issuance of the shares of Preferred Stock in one or more classes or one or more series, with such voting powers, full or limited, or no voting powers, and with such designations, preferences and relative, participating, optional and other special rights, and qualifications, limitations or restrictions thereof, if any, as shall be stated and expressed in the resolution or resolutions providing for such issue adopted by the Board of Directors. Except as otherwise provided by law, the holders of the Preferred Stock of the Corporation shall only have such voting rights as are provided for or expressed in the resolutions of the Board of Directors relating to such Preferred Stock adopted pursuant to the authority contained in the Articles of Incorporation. Before issuance of any such shares of Preferred Stock, the Corporation shall file Articles Supplementary with the State Department of Assessment and Taxation of Maryland in accordance with the provision of Section 2-208 of the Maryland General Corporation Law. E. RESERVATION OF SHARES. Pursuant to the obligations of the Corporation under the Partnership Agreement to issue shares of Common Stock in exchange for Units, the Board of Directors is hereby required to reserve a sufficient number of authorized but unissued shares of Common Stock to permit the Corporation to issue shares of Common Stock in exchange for Units that may be exchanged for shares of Common Stock pursuant to the Partnership Agreement. F. NYSE SETTLEMENT. Nothing in this Article IV shall preclude the settlement of any transaction entered into through the facilities of the NYSE. G. PREEMPTIVE RIGHTS. No holder of shares of capital stock of the Corporation shall, as such holder, have any preemptive or other right to purchase or subscribe for any shares of Common Stock, Excess Shares or any class of capital stock of the Corporation which the Corporation may issue or sell. H. CONTROL SHARES. Pursuant to Section 3-702(b) of the General Corporation Law of Maryland (the "Act"), the terms of Subtitle 7 of Title 3 of the Act shall be inapplicable to any acquisition of a Control Share (as defined in the Act) that is not prohibited by the terms of Article IV.

The number of directors which will constitute the entire Board of Directors shall be fixed by, or in the manner provided in, the By-laws but shall in no event be less than three. C. CLASSIFICATION. The directors shall be classified, with respect to the time for which they severally hold office, into three classes, as nearly equal in number as possible, as shall be provided in the By-laws of the Corporation, one class to be originally elected for a term expiring at the annual meeting of stockholders to be held in 1994, another class to be originally elected for a term expiring at the annual meeting of stockholders to be held in 1995, and another class to be originally elected for a term expiring at the annual meeting of stockholders to be held in 1996, with each class to hold office until its successors are elected and qualified. At each annual meeting of the stockholders of the Corporation, the date of which shall be fixed by or pursuant to the By-laws of the Corporation, the successors of the class of directors whose terms expire at that meeting shall be elected to hold office for a term expiring at the annual meeting of stockholders held in the third year following the year of their election.

Any director elected in accordance with the preceding sentence shall hold office until the next annual meeting of the Corporation, at which time a successor shall be elected to fill the remaining term of the position filled by such director.

(iv) Any dividend or distribution paid prior to the discovery by the Corporation that shares of Common Stock have been transferred in violation of subparagraph B(4)(b) of this Article IV, shall be repaid to the Corporation upon demand and shall be held in trust for the Designated Charity.

(j) LIMITATIONS ON MODIFICATIONS. (i) From the date of the Initial Public Offering and prior to the Restriction Termination Date, neither the Ownership Limit nor any Existing Holder Limit may be increased (nor may any additional Existing Holder Limit be created) if, after giving effect to such increase (or creation), five Persons who are Beneficial Owners of Common Stock (including all of the then Existing Holders) could (taking into account the Ownership Limit and the Existing Holder Limit) Beneficially Own, in the aggregate, more than 49% of the outstanding Common Stock. (ii) Prior to the modification of any Existing Holder Limit or Ownership Limit pursuant to subparagraph B(4)(i) of this Article IV, the Board of Directors of the Corporation may require such opinions of counsel, affidavits, undertakings or agreements as it may deem necessary or advisable in order to determine or ensure the Corporation's status as a REIT.

(ii) Prior to granting any exception pursuant to subparagraph B(4)(k)(i) of this Article IV, 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. 5.

Dividends shall be payable to holders of record as they appear in the share records of the Corporation at the close of business on the applicable record date (a "Record Date"), which shall be the 1st day of the calendar month in which the applicable Quarterly Dividend Date falls on or such other date designated by the Board of Directors of the Corporation for the payment of dividends that is not more than 30 nor less than 10 days prior to such Quarterly Dividend Date. The amount of any dividend payable for any Dividend Period shorter than a full Dividend Period shall be computed on the basis of a 360-day year of twelve 30-day months. "Business Day" shall mean any day, other than a Saturday or Sunday, that is neither a legal holiday nor a day on which banking institutions in The City of New York are authorized or required by law, regulation or executive order to close. (B) The amount of any dividends accumulated on any Series A Preferred Shares at any Quarterly Dividend Date shall be the amount of any unpaid dividends accumulated thereon to but excluding such Quarterly Dividend Date and the amount of dividends accumulated on any shares of Series A Preferred Shares at any date other than a Quarterly Dividend Date shall be equal to the sum of the amount of any unpaid dividends accumulated thereon to but excluding the last preceding Quarterly Dividend Date, plus an amount calculated on the basis of the annual dividend rate of $4.1875 per share for the period after such last preceding Quarterly Dividend Date to and including the date as of which the calculation is made based on a 360-day year of twelve 30-day months. Dividends on the Series A Preferred Shares will accumulate whether or not the Corporation has earnings, whether or not there are funds legally available for the payment of such dividends and whether or not such dividends are authorized or declared. (C) Except as otherwise expressly provided herein, the Series A Preferred Shares will not be entitled to any dividends in excess of full cumulative dividends as described above and shall not be entitled to participate in the earnings or assets of the Corporation, and no interest, or sum of money in lieu of interest, shall be payable in respect of any dividend payment or payments on the Series A Preferred Shares which may be in arrears. (D) Any dividend payment made on the Series A Preferred Shares shall first be credited against the earliest accumulated but unpaid dividend due with respect to such shares which remains payable. (E) If, for any taxable year, the Corporation elects to designate as "capital gain dividends" (as defined in and permitted pursuant to Section 857 of the Internal Revenue Code of 1986, as amended (the "Code")), any portion (the "Capital Gains Amount") of the dividends paid or made available for the year to holders of all classes of shares (the "Total Dividends"), then the portion of the Capital Gains Amount that shall be allocated to the holders of the Series A Preferred Shares shall equal (i) the Capital Gains Amount multiplied by (ii) a fraction that is equal to (a) the total dividends paid or made available to the holders of the Series A Preferred Shares for the year over (b) the Total Dividends. (F) No dividends on the Series A Preferred Shares shall be authorized by the Board of Directors of the Corporation or be paid or set apart for payment by the Corporation at such time as the terms and provisions of any agreement of the Corporation, including any agreement relating to its indebtedness, prohibits such authorization, payment or setting apart for payment or provides that such authorization, payment or setting apart for payment would constitute a breach thereof or a default thereunder, or if such authorization or payment shall be restricted or prohibited by law. (G) No dividends will be declared or paid or set apart for payment on any capital stock of the Corporation ranking, as to dividends, on a parity with or junior to the Series A Preferred Shares for any period unless full cumulative dividends have been or contemporaneously are declared and paid or declared and a sum sufficient for the payment therefor set apart for such payment on the Series A Preferred Shares for all past Dividend Periods and the then current Dividend Period. When dividends are not paid in full (or a sum sufficient for such full payment is not so set apart) upon the Series A Preferred Shares and the shares of any other series of Preferred Stock ranking on a parity as to dividends with the Series A Preferred Shares, all dividends declared on the Series A Preferred Shares and any other series of Preferred Stock ranking on a parity as to dividends with the Series A Preferred Shares shall be declared pro rata so that the amount of dividends declared per Series A Preferred Share and such other series of Preferred Stock shall in all cases bear to each other the same ratio that accumulated dividends per Series A Preferred Share and such other series of Preferred Stock bear to each other. (H) Except as provided in subparagraph G, unless full cumulative dividends on the Series A Preferred Shares have been or contemporaneously are declared and paid or declared and a sum sufficient for the payment therefor set apart for such payment on the Series A Preferred Shares for all past Dividend Periods and the then current Dividend Period, no dividends (other than in Junior Shares) shall be declared or paid or set aside for payment nor shall any other distribution be declared or made upon the Junior Shares or any other capital stock of the Corporation ranking on a parity with the Series A Preferred Shares as to dividends or upon liquidation, nor shall any Junior Shares or any other capital stock of the Corporation ranking on a parity with the Series A Preferred Shares as to dividends or upon liquidation be redeemed, purchased or otherwise acquired for any consideration (or any moneys be paid or made available for a sinking fund for the redemption of such shares) by the Corporation (except by conversion into or exchange for other Junior Shares). (v) LIQUIDATION RIGHTS. (A) Upon the voluntary or involuntary dissolution, liquidation or winding up of the Corporation (a "liquidation"), the holders of the Series A Preferred Shares then outstanding shall be entitled to receive in cash or property (at its fair market value determined by the Corporation's Board of Directors) and to be paid out of the assets of the Corporation legally available for distribution to its shareholders, before any payment or distribution shall be made on any Junior Shares, the amount of $50.00 per share, plus accumulated and unpaid dividends, if any, thereon to and including the date of liquidation. (B) After the payment to the holders of the Series A Preferred Shares of the full liquidation amounts provided for in paragraph (A), the holders of the Series A Preferred Shares, as such, shall have no right or claim to any of the remaining assets of the Corporation. (C) If, upon any voluntary or involuntary dissolution, liquidation, or winding up of the Corporation, the amounts payable with respect to the preference distributions on the Series A Preferred Shares and the shares of each other series of Preferred Stock of the Corporation ranking, as to liquidation rights, on a parity with the Series A Preferred Shares are not paid in full, the holders of the Series A Preferred Shares and any other shares of Preferred Stock of the Corporation ranking, as to liquidation rights, on a parity with the Series A Preferred Shares shall share ratably in any such distribution of assets of the Corporation in proportion to the full respective preference amounts to which they would otherwise be respectively entitled. (D) Neither the sale, lease, transfer or conveyance of all or substantially all of the property or business of the Corporation, nor the merger or consolidation of the Corporation into or with any other entity or the merger or consolidation of any other entity into or with the Corporation, shall be deemed to be a dissolution, liquidation or winding up, voluntary or involuntary, for the purposes of this paragraph (v). (vi) REDEMPTION. (A) OPTIONAL REDEMPTION. On and after October 15, 2027, the Corporation may, at its option (subject to the provisions of this paragraph (vi)), redeem at any time all or, from time to time, part of the Series A Preferred Shares at a price per share (the "Redemption Price"), payable in cash, of $50.00 per share, together with all accumulated and unpaid dividends, if any, to and including the date fixed for redemption (the "Redemption Date"), without interest, to the extent the Corporation has funds legally available therefor. The Series A Preferred Shares have no stated maturity and will not be subject to any sinking fund or mandatory redemption provisions, except as provided for in paragraph (ix) below. (B) PROCEDURES FOR REDEMPTION. (1) Notice of redemption will be given by publication in a newspaper of general circulation in The City of New York, such publication to be made once a week for two successive weeks commencing not less than 30 nor more than 60 days prior to the Redemption Date. Notice of any redemption furnished by the Corporation will also be mailed by the registrar, postage prepaid, not less than 30 nor more than 60 days prior to the Redemption Date, addressed to each holder of record of the Series A Preferred Shares to be redeemed at the address set forth in the share transfer records of the registrar. No failure to give such notice or any defect therein or in the mailing thereof shall affect the validity of the proceedings for the redemption of any Series A Preferred Shares except as to the holder to whom the Corporation has failed to give notice or except as to the holder to whom notice was defective. In addition to any information required by law or by the applicable rules of any exchange upon which Series A Preferred Shares may be listed or admitted to trading, such notice shall state: (a) the Redemption Date; (b) the Redemption Price; (c) the number of Series A Preferred Shares to be redeemed; (d) the place or places where certificates for the Series A Preferred Shares to be redeemed are to be surrendered for payment of the Redemption Price; and (e) that dividends on the Series A Preferred Shares to be redeemed will cease to accumulate on the Redemption Date. (2) If notice has been mailed in accordance with paragraph (vi)(B)(1) above and provided that on or before the Redemption Date specified in such notice all funds necessary for such redemption shall have been irrevocably set aside by the Corporation, separate and apart from its other funds, in trust for the pro rata benefit of the holders of the Series A Preferred Shares so called for redemption, so as to be, and to continue to be available therefor, then, from and after the Redemption Date, dividends on the Series A Preferred Shares so called for redemption shall cease to accumulate, and said shares shall no longer be deemed to be outstanding and shall not have the status of Series A Preferred Shares and all rights of the holders thereof as shareholders of the Corporation (except the right to receive the Redemption Price) shall cease. Upon surrender, in accordance with such notice, of the certificates for any Series A Preferred Shares so redeemed (properly endorsed or assigned for transfer, if the Corporation shall so require and the notice shall so state), such Series A Preferred Shares shall be redeemed by the Corporation at the Redemption Price. In case fewer than all the Series A Preferred Shares represented by any such certificate are redeemed, a new certificate or certificates shall be issued representing the unredeemed Series A Preferred Shares without cost to the holder thereof. (3) Any funds deposited with a bank or trust company for the purpose of redeeming Series A Preferred Shares shall be irrevocable except that: (a) the Corporation shall be entitled to receive from such bank or trust company the interest or other earnings, if any, earned on any money so deposited in trust, and the holders of any Series A Preferred Shares redeemed shall have no claim to such interest or other earnings; and (b) any balance of monies so deposited by the Corporation and unclaimed by the holders of the Series A Preferred Shares entitled thereto at the expiration of two years from the applicable Redemption Date shall be repaid, together with any interest or other earnings earned thereon, to the Corporation, and after any such repayment, the holders of the Series A Preferred Shares entitled to the funds so repaid to the Corporation shall look only to the Corporation for payment without interest or other earnings. (4) No Series A Preferred Shares may be redeemed except from proceeds from the sale of other capital stock of the Corporation (consisting of common stock, preferred stock, depositary shares, interests, participations or other ownership interests (however designated) and any rights (other than debt securities convertible into or exchangeable for equity securities) or options to purchase any of the foregoing) and not from any other source. (5) Unless full accumulated dividends on all Series A Preferred Shares shall have been or contemporaneously are declared and paid or declared and a sum sufficient for the payment thereof set apart for payment on the Series A Preferred Shares for all past Dividend Periods and the then current Dividend Period, no Series A Preferred Shares shall be redeemed, purchased or otherwise acquired directly or indirectly on the Series A Preferred Shares; provided, however, that the foregoing shall not prevent the redemption, purchase or acquisition of Series A Preferred Shares to preserve the Corporation's REIT status or the purchase or acquisition of Series A Preferred Shares pursuant to a purchase or exchange offer made on the same terms to holders of all outstanding Series A Preferred Shares. (6) If the Redemption Date is after a Record Date and before the related Quarterly Dividend Date, the dividend payable on such Quarterly Dividend Date shall be paid to the holder in whose name the Series A Preferred Shares to be redeemed are registered at the close of business on such Record Date notwithstanding the redemption thereof between such Record Date and the related Quarterly Dividend Date or the Corporation's default in the payment of the dividend due. Except as provided in this paragraph (vi), the Corporation will make no payment or allowance for unpaid dividends, whether or not in arrears, on Series A Preferred Shares to be redeemed. (7) In case of redemption of less than all Series A Preferred Shares at the time outstanding, the Series A Preferred Shares to be redeemed shall be selected pro rata from the holders of record of such Series A Preferred Shares in proportion to the number of Series A Preferred Shares held by such holders (with adjustments to avoid redemption of fractional shares) or by any other equitable method determined by the Corporation. (vii) VOTING RIGHTS. Except as required by law, and as set forth below, the holders of the Series A Preferred Shares shall not be entitled to vote at any meeting of the shareholders for election of Directors or for any other purpose or otherwise to participate in any action taken by the Corporation or the shareholders thereof, or to receive notice of any meeting of shareholders. (A) Whenever dividends on any Series A Preferred Shares shall be in arrears for six or more quarterly periods, whether or not such quarterly periods are consecutive, the holders of such Series A Preferred Shares (voting separately as a class with all other series of Preferred Stock of the Corporation upon which like voting rights have been conferred and are exercisable) will be entitled to vote for the election of two additional Directors of the Corporation at a special meeting called by the holders of record of at least ten percent (10%) of the Series A Preferred Shares (unless such request is received less than 90 days before the date fixed for the next annual or special meeting of the shareholders) or at the next annual meeting of shareholders, and at each subsequent annual meeting until all dividends accumulated on such Series A Preferred Shares for the past Dividend Periods and the then current Dividend Period shall have been fully paid or declared and a sum sufficient for the payment thereof set aside for payment. In such case, the entire Board of Directors of the Corporation will be increased by two Directors. (B) So long as any Series A Preferred Shares remain outstanding, the Corporation will not, without the affirmative vote or consent of the holders of at least two-thirds of the Series A Preferred Shares outstanding at the time, given in person or by proxy, either in writing or at a meeting (voting separately as a class), (i) authorize or create, or increase the authorized or issued amount of, any class or series of shares of capital stock ranking senior to the Series A Preferred Shares with respect to the payment of dividends or the distribution of assets upon liquidation, dissolution or winding up of the Corporation or reclassify any authorized capital stock of the Corporation into such capital stock, or create, authorize or issue any obligation or security convertible into or evidencing the right to purchase any such capital stock; or (ii) amend, alter or repeal the provisions of the Corporation's Articles of Incorporation, including these Articles Supplementary, whether by merger, consolidation or otherwise (an "Event"), so as to materially and adversely affect any right, preference, privilege or voting power of the Series A Preferred Shares or the holders thereof; provided, however, with respect to the occurrence of any of the Events set forth in (ii) above, so long as the Series A Preferred Shares remain outstanding with the terms thereof materially unchanged, taking into account that upon the occurrence of an Event, the Corporation may not be the surviving entity, the occurrence of any such Event shall not be deemed to materially and adversely affect such rights, preferences, privileges or voting power of holders of Series A Preferred Shares; and provided, further, that (x) any increase in the amount of the authorized Preferred Stock or the creation or issuance of any other series of Preferred Stock, or (y) any increase in the amount of authorized Series A Preferred Shares, in each case ranking on a parity with or junior to the Series A Preferred Shares with respect to payment of dividends and the distribution of assets upon liquidation, dissolution or winding up, shall not be deemed to materially and adversely affect such rights, preferences, privileges or voting powers. The foregoing voting provisions will not apply if, at or prior to the time when the act with respect to which such vote or consent would otherwise be required shall be effected, all outstanding Series A Preferred Shares shall have been redeemed or called for redemption and sufficient funds shall have been deposited in trust to effect such redemption. (C) On each matter submitted to a vote of the holders of Series A Preferred Shares in accordance with this paragraph (vii), or as otherwise required by law, each Series A Preferred Share shall be entitled to one vote. With respect to each Series A Preferred Share, the holder thereof may designate a proxy, with each such proxy having the right to vote on behalf of the holder. (viii) CONVERSION. The Series A Preferred Shares are not convertible into or exchangeable for any other property or securities of the Corporation. (ix) RESTRICTIONS ON OWNERSHIP. (A) Definitions. The following terms shall have the following meanings: (1) "Beneficial Ownership" shall mean ownership of the Series A Preferred Shares by a Person who would be treated as an owner of such Series A Preferred Shares either directly or constructively through the application of Section 544 of the Code, as modified by Section 856(h) of the Code. The terms "Beneficial Owner," "Beneficially Owns" and "Beneficially Owned" shall have the correlative meanings. (2) "Code" shall mean the Internal Revenue Code of 1986, as amended from time to time. (3) "Constructive Ownership" shall mean ownership of Series A Preferred Shares by a Person who would be treated as an owner of such Series A Preferred Shares either directly or constructively through the application of Section 318 of the Code, as modified by Section 856(d)(5) of the Code. The terms "Constructive Owner," "Constructively Owns" and "Constructively Owned" shall have the correlative meanings. (4) "Initial Placement" shall mean the sale of Series A Preferred Shares pursuant to the Corporation's Offering Memorandum dated October 7, 1997. (5) "Ownership Limit" shall initially mean 7% of the outstanding Series A Preferred Shares of the Corporation. (6) "Person" shall mean an individual, corporation, partnership, estate, trust, a portion of a trust permanently set aside for or to be used exclusively for the purposes described in Section 642(c) of the Code, association, private foundation within the meaning of Section 509(a) of the Code, joint stock company or other entity and also includes a group as that term is used for purposes of Section 13(d)(3) of the Securities Exchange Act of 1934, as amended; but does not include an underwriter which participates in a public offering of the Series A Preferred Shares provided that the ownership of Series A Preferred Shares by such underwriter would not result in the Corporation failing to qualify as a REIT. (7) "REIT" shall mean a Real Estate Investment Trust under Section 856 of the Code. (8) "Restriction Termination Date" shall mean the first day after the date of the Initial Placement on which the Board of Directors of the Corporation determines that it is no longer in the best interests of the Corporation to attempt to, or continue to, qualify as a REIT. (9) "Transfer" shall mean any sale, transfer, gift, assignment, devise or other disposition of Series A Preferred Shares or the right to vote or receive dividends on Series A Preferred Shares (including (A) the granting of any option or entering into any agreement for the sale, transfer or other disposition of Series A Preferred Shares or the right to vote or receive dividends on Series A Preferred Shares or (B) the sale, transfer, assignment or other disposition or grant of any securities or rights convertible into or exchangeable for Series A Preferred Shares, or the right to vote or receive dividends on Series A Preferred Shares), whether voluntary or involuntary, whether of record or Beneficially or Constructively (including transfers of interests in other entities which result in changes in Beneficial or Constructive Ownership of Series A Preferred Shares), and whether by operation of law or otherwise. (B) Restrictions. (1) During the period commencing on the date of the Initial Placement and prior to the Restriction Termination Date: (a) no Person shall Beneficially Own any Series A Preferred Shares in excess of the Ownership Limit; (b) no Person shall Beneficially Own any shares of Series A Preferred Shares if, as a result of such Beneficial Ownership, the Series A Preferred Shares and Common Stock of the Corporation would be Beneficially Owned by less than 100 Persons (determined without reference to the rules of attribution under Section 544 of the Code); and (c) no Person shall Beneficially Own any shares if, as a result of such Beneficial Ownership, the Corporation would be "closely held" within the meaning of Section 856(h) of the Code or would otherwise result in the Corporation failing to qualify as a REIT.. (2) Any Transfer that would result in a violation of the restrictions in subparagraph (ix)(B)(1) shall be void ab initio as to the Transfer of such Series A Preferred Shares that would cause the violation of the applicable restriction in subparagraph (ix)(B)(1), and the intended transferee shall acquire no rights in such Series A Preferred Shares. (C) Remedies for Breach. (1) If the Board of Directors or a committee thereof shall at any time determine in good faith that a Transfer or other event has taken place in violation of subparagraph (ix)(B)(1) or that a Person intends to acquire or has attempted to acquire Beneficial Ownership of any shares of the Corporation that will result in violation of subparagraph (ix)(B)(1) (whether or not such violation is intended and determined without reference to any rules of attribution), the Corporation shall inform the Purported Transferee of its obligations hereunder, including such Purported Transferee's obligations to pay over to the Charitable Trust any and all dividends received with result to the Trust Shares. In addition, the Board of Directors or a committee thereof shall take such action as it or they deem advisable to refuse to give effect to or to prevent such Transfer, including, but not limited to, refusing to give effect to such Transfer on the books of the Corporation or instituting proceedings to enjoin such Transfer and to receive any dividend erroneously paid and declaring any votes erroneously cast to be retroactively invalid; 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 subparagraph (ix)(B)(1) shall automatically result in a transfer to the Charitable Trust as described in subparagraph (C)(2), irrespective of any action (or non-action) by the Board of Directors or committee. (2) If, notwithstanding the other provisions contained in subparagraph (ix)(B)(1), at any time after the date of the Initial Placement and prior to the Restriction Termination Date, there is a purported Transfer (whether or not such Transfer is the result of a transaction entered into through the facilities of the NYSE), change in the capital structure of the Corporation, or other event such that one or more of the restrictions on ownership and transfers described in subparagraph (ix)(B)(1) above has been violated, then the Series A Preferred Shares being Transferred (or in the case of an event other than a Transfer, the shares owned or Constructively Owned or Beneficially Owned) (the Person making such Transfer being the "Purported Transferee") which would cause one or more of the restrictions on ownership or transfer to be violated (rounded up to the nearest whole share) (the "Trust Shares"), shall automatically be transferred to the Corporation, as Trustee of a trust (the "Charitable Trust") for the exclusive benefit of The American Cancer Society (the "Designated Charity"), an organization described in Section 170(b)(1)(A) and 170(c) of the Code. The Purported Transferee shall have no rights in such Trust Shares. (3) The Corporation, as Trustee of the Charitable Trust, may transfer the shares held in such trust to a Person whose ownership of the shares will not result in a violation of the ownership restrictions (a "Permitted Transferee"). If such a transfer is made, the interest of the Designated Charity will terminate and proceeds of the sale will be payable to the Purported Transferee and to the Designated Charity. The Purported Transferee will receive the lesser of (1) the price paid by the Purported Transferee for the shares or, if the Purported Transferee did not give value for the shares, the market price of the shares as determined by the Board of Directors on the day of the event causing the shares to be held in trust, and (2) the price per share received by the Corporation, as Trustee, from the sale or other disposition of the shares held in trust. The Designated Charity will receive any proceeds in excess of the amount payable to the Purported Transferee. The Purported Transferee will not be entitled to designate a Permitted Transferee. (4) All stock held in the Charitable Trust will be deemed to have been offered for sale to the Corporation or its designee for a 90-day period, at the lesser of the price paid for that stock by the Purported Transferee and the market price on the date that the Corporation accepts the offer. This period will commence on the date of the violative transfer, if the Purported Transferee gives notice to the Corporation of the transfer, or the date that the Board of Directors of the Corporation determines that a violative transfer occurred, if no such notice is provided. (5) Any dividend or distribution paid prior to the discovery by the Corporation that Series A Preferred Shares have been transferred in violation of subparagraph (ix)(B)(1) shall be repaid to the Corporation upon demand and shall be held in trust for the Designated Charity. Any dividend or distribution declared but unpaid shall be rescinded as void ab initio with respect to such shares of stock. (6) Subject to the preferential rights of the Series A Preferred Shares, in the event of any voluntary or involuntary liquidation, dissolution or winding up of, or any distribution of the assets of, the Corporation, the Designated Charity shall be entitled to receive, ratably with each other holder of Series A Preferred Shares, that portion of the assets of the Corporation available for distribution to its stockholders as the number of Trust Shares bears to the total number of shares of Series A Preferred Shares then outstanding (including the Trust Shares). The Corporation, as Trustee, or if the Corporation shall have been dissolved, any trustee appointed by the Corporation prior to its dissolution, shall distribute to the Designated Charity, when determined (or if not determined, or only partially determined, ratably to the other holders of Series A Preferred Shares who have been determined and the Designated Charity), any such assets received in respect of the Trust Shares in any liquidation, dissolution or winding up of, or any distribution of the assets of, the Corporation. (7) The Purported Transferee will not be entitled to vote any Series A Preferred Shares it attempts to acquire, and any stockholder vote will be rescinded if a Purported Transferee votes and the stockholder vote would have been decided differently if such Purported Transferee's vote was not counted. (D) Notice of Restricted Transfer. Any Person who acquires or attempts to acquire shares in violation of subparagraph (ix)(B)(1) or any Person who is a Purported Transferee shall immediately give written notice to the Corporation of such event 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. (E) Owners Required To Provide Information. From the date of the Initial Placement and prior to the Restriction Termination Date each Person who is a Beneficial Owner or Constructive Owner of Series A Preferred Shares and each Person (including the shareholder of record) who is holding Series A Preferred Shares for a Beneficial Owner or Constructive Owner shall provide to the Corporation such information as the Corporation may request, in good faith, in order to determine the Corporation's status as a REIT. (F) Remedies Not Limited. Except as provided in subparagraph (ix)(M), nothing contained in this paragraph (ix) 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 shareholders in preserving the Corporation's status as a REIT. (G) Ambiguity. In the case of an ambiguity in the application of any of the provisions of this paragraph (ix), including any definition contained in subparagraph (ix)(A), the Board of Directors shall have the power to determine the application of the provisions of this paragraph (ix) with respect to any situation based on the facts known to it. (H) Modification of Ownership Limit. Subject to the limitations provided in subparagraph (ix)(I), the Board of Directors may from time to time increase the Ownership Limit and shall file Articles Supplementary with the State Department of Assessments and Taxation of Maryland to evidence such increase. (I) Limitations on Modifications. (1) The Ownership Limit may not be increased if, after giving effect to such increase, five Persons who are Beneficial Owners (including ownership of Common Stock for purposes of this subparagraph (ix)(I)(1)), Beneficially Own in the aggregate, more than 49.0% in value of the outstanding shares of stock of the Corporation. (2) Prior to the modification of the Ownership Limit pursuant to subparagraph (ix)(H), the Board of Directors of the Corporation may require such opinions of counsel, affidavits, undertakings or agreements as it may deem necessary or advisable in order to determine or ensure the Corporation's status as a REIT. (J) Legend. Each certificate for Series A Preferred Shares shall bear a legend referring to the restrictions described above. (K) Termination of REIT Status. The Board of Directors shall take no action to terminate the Corporation's status as a REIT or to amend the provisions of this subparagraph (ix) until such time as (A) the Board of Directors adopts a resolution recommending that the Corporation terminate its status as a REIT or amend this subparagraph (ix), as the case may be, (B) the Board of Directors presents the resolution at an annual or special meeting of the shareholders and (C) such resolution is approved by holders of a majority of the issued and outstanding Series A Preferred Shares. (L) Severability. If any provision of this paragraph (ix) or any application of any such provision is determined to be invalid by any Federal or state court having jurisdiction over the issues, the validity of the remaining provisions shall not be affected and other applications of such provision shall be affected only to the extent necessary to comply with the determination of such court. (M) NYSE Settlement. Nothing in these Articles Supplementary shall preclude the settlement of any transaction with respect to the Series A Preferred Shares of the Corporation entered into through the facilities of the New York Stock Exchange. (N) Exceptions. (i) The Board of Directors, in its sole discretion, may exempt a Person from the Ownership Limit if such Person is not an individual for purposes of Section 542(a)(2) of the Code and the Board of Directors obtains such representations and undertakings from such Person as are reasonably necessary to ascertain that no individual's Beneficial Ownership of such Series A Preferred Shares will violate the Ownership Limit, and agrees that any violation of such representations or undertaking (or other action which is contrary to the restrictions contained in this paragraph (ix)) or attempted violation will result in such Series A Preferred Shares automatically being transferred to the Charitable Trust. (ii) Prior to granting any exception pursuant to subparagraph N, 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.
