A class of Preferred Stock, designated the "7.95% Series K Cumulative Redeemable Preferred Stock" (the "Series K Preferred Stock"), is hereby established. The number of shares of Series K Preferred Stock shall be 800,000 (the "Series K Preferred Shares"). (2) RANK. The Series K Preferred Shares will rank, with respect to dividend rights and rights upon voluntary or involuntary liquidation, dissolution or winding up of the Corporation, (a) senior to all classes or series of Common Stock (as defined in the Charter) and to all equity securities of the Corporation the terms of which provide that such equity securities shall rank junior to such Series K Preferred Shares; (b) on a parity with the Series A Preferred Stock, the Series B Preferred Stock, the Series D Preferred Stock, the Series E Preferred Stock, the Series F Preferred Stock, the Series G Preferred Stock, the Series H Preferred Stock, the Series I Preferred Stock, the Series J Preferred Stock and all equity securities issued by the Corporation other than those referred to in clauses (a) and (c) (it being the intent of the Corporation that the Series K 2 Preferred Stock be on a parity with the Series A Preferred Stock, the Series B Preferred Stock, the Series D Preferred Stock, the Series E Preferred Stock, the Series F Preferred Stock, the Series G Preferred Stock, the Series H Preferred Stock, the Series I Preferred Stock and the Series J Preferred Stock with respect to dividend rights and rights upon voluntary or involuntary liquidation, dissolution or winding up of the Corporation, notwithstanding any provision contained in these Articles Supplementary, which, if given effect, would make the Series K Preferred Stock not in parity with the Series A Preferred Stock, the Series B Preferred Stock, the Series D Preferred Stock, the Series E Preferred Stock, the Series F Preferred Stock, the Series G Preferred Stock, the Series H Preferred Stock, the Series I Preferred Stock and the Series J Preferred Stock; and any such provision contained in these Articles Supplementary shall be of no force or effect); and (c) junior to all equity securities issued by the Corporation which rank senior to the Series K Preferred Shares in accordance with Section 6(d) of this Article Third. The term "equity securities" does not include convertible debt securities, until the same are converted into equity securities. (3) DIVIDENDS. (a) Holders of Series K Preferred Shares shall be entitled to receive, if, when and as authorized by the Board, out of funds legally available for the payment of dividends, cumulative preferential cash dividends at the rate of 7.95% of the $50.00 liquidation preference per annum (equivalent to $3.975 per annum per share). Such dividends shall accumulate on a daily basis computed on the basis of a 360-day year consisting of twelve 30-day months and be cumulative, shall accrue from the original date of issuance and shall be payable quarterly (such quarterly periods for purposes of payment and accrual will be the quarterly periods ending on the dates specified in this sentence and not calendar year quarters) in equal amounts in arrears on the 15th day of each January, April, July and October or, if not a business day, the next succeeding business day (each a "Dividend Payment Date"). 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 (each, a "Dividend Record Date"), which shall be the date designated by the Board for the payment of dividends that is not more than 30 nor less than 10 days prior to the applicable payment date therefor. Any dividend payable on the Series K Preferred Shares for any partial dividend period shall be prorated and computed on the basis of a 360-day year consisting of twelve 30-day months. If any date on which distributions are to be made on the Series K Preferred Stock is not a Business Day (as defined herein), then payment of the distribution to be made on such date will be made on the next succeeding day that is a Business Day (and without any interest or other payment in respect of any such delay) 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 made on such date. Notwithstanding any provision to the contrary contained herein, each outstanding share of Series K Preferred Stock shall be entitled to receive, and shall receive, a dividend with respect to any Dividend Record Date equal to the dividend paid with respect to each other share of Series K Preferred Stock which is outstanding on such date which shall be equal to the greatest dividend per share payable on any such share on such date. In addition, notwithstanding anything to the contrary set forth herein, each share of Series K Preferred Stock shall also continue to accrue all accrued and unpaid distributions up to the exchange date on any Series K Preferred Unit (as defined in the Sixth Amended and Restated Agreement of Limited Partnership of AMB Property, L.P., dated as of April 17, 2002, as amended and supplemented from time to time (the 3 "Partnership Agreement")) validly exchanged into such share of Series K Preferred Stock in accordance with the provisions of the Partnership Agreement. (b) No dividend on the Series K Preferred Shares shall be authorized by the Board 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. (c) Notwithstanding anything to the contrary contained herein, dividends on the Series K Preferred Shares shall accumulate whether or not restrictions exist in respect thereof, whether or not there are funds legally available for the payment thereof and whether or not such dividends are declared or authorized. Accrued but unpaid dividends on the Series K Preferred Shares will accumulate as of the Dividend Payment Date on which they first become payable or on the date of redemption, as the case may be. (d) If any Series K Preferred Shares are outstanding, no full dividends will be declared or paid or set apart for payment on any other equity securities of the Corporation of any other class or series ranking, as to distributions or upon voluntary or involuntary liquidation, dissolution or winding up of the Corporation, junior to or on a parity with the Series K Preferred Shares (including the Series A Preferred Stock, the Series B Preferred Stock, the Series D Preferred Stock, the Series E Preferred Stock, the Series F Preferred Stock, the Series G Preferred Stock, the Series H Preferred Stock, the Series I Preferred Stock and the Series J Preferred Stock) unless full cumulative dividends have been or contemporaneously are declared and paid or declared and a sum sufficient for the payment thereof irrevocably set apart in trust for such payment on the Series K Preferred Shares for all dividend periods. When dividends are not paid in full (or a sum sufficient for such full payment is not so set apart) upon the Series K Preferred Shares and any other equity securities ranking as to distributions on a parity with the Series K Preferred Shares (including the Series A Preferred Stock, the Series B Preferred Stock, the Series D Preferred Stock, the Series E Preferred Stock, the Series F Preferred Stock, the Series G Preferred Stock, the Series H Preferred Stock, the Series I Preferred Stock and the Series J Preferred Stock), all dividends declared upon the Series K Preferred Shares and any other equity securities of the Corporation ranking on a parity with the Series K Preferred Stock as to distributions and upon voluntary or involuntary liquidation, dissolution or winding up of the Corporation (including the Series A Preferred Stock, the Series B Preferred Stock, the Series D Preferred Stock, the Series E Preferred Stock, the Series F Preferred Stock, the Series G Preferred Stock, the Series H Preferred Stock, the Series I Preferred Stock and the Series J Preferred Stock) shall be declared pro rata so that the amount of dividends declared per Series K Preferred Share and each such other equity securities shall in all cases bear to each other the same ratio that accumulated dividends per Series K Preferred Share and such other equity securities (which shall not include any accumulation in respect of unpaid dividends for prior dividend periods if such other equity securities do not have a cumulative dividend) bear to each other. No interest, or sum of money in lieu of interest, shall be payable in respect of any dividend payment or payments on Series K Preferred Shares which may be in arrears. 4 (e) Except as provided in the immediately preceding paragraph, unless full cumulative dividends on the Series K Preferred Shares have been or contemporaneously are declared and paid or declared and a sum sufficient for the payment thereof is irrevocably set apart in trust for payment for all dividend periods, no dividends (other than in Common Stock or other equity securities of the Corporation ranking junior to the Series K Preferred Shares as to distributions and upon voluntary or involuntary liquidation, dissolution and winding up of the Corporation) shall be declared or paid or set aside for payment nor shall any other dividend be declared or made upon the Common Stock or any other equity securities of the Corporation ranking as to distributions or upon voluntary or involuntary liquidation, dissolution or winding up of the Corporation junior to or on a parity with the Series K Preferred Stock (including the Series A Preferred Stock, the Series B Preferred Stock, the Series D Preferred Stock, the Series E Preferred Stock, the Series F Preferred Stock, the Series G Preferred Stock, the Series H Preferred Stock, the Series I Preferred Stock and the Series J Preferred Stock), nor shall any Common Stock or any other equity securities of the Corporation ranking junior to or on a parity with the Series K Preferred Stock as to distributions or upon voluntary or involuntary liquidation, dissolution or winding up of the Corporation (including the Series A Preferred Stock, the Series B Preferred Stock, the Series D Preferred Stock, the Series E Preferred Stock, the Series F Preferred Stock, the Series G Preferred Stock, the Series H Preferred Stock, the Series I Preferred Stock and the Series J Preferred Stock) be redeemed, purchased or otherwise acquired for any consideration (or any monies be paid to or made available for a sinking fund for the redemption of any such securities) by the Corporation (except by conversion into or exchange for other equity securities of the Corporation ranking junior to the Series K Preferred Stock as to distributions and upon voluntary and involuntary liquidation, dissolution and winding up of the Corporation, and except pursuant to Section 7 of this Article Third to ensure the Corporation's continued status as a real estate investment trust (a "REIT") for Federal income tax purposes or comparable Charter provisions with respect to other classes or series of the Corporation's stock). (f) Accumulated but unpaid dividends on the Series K Preferred Shares will not bear interest and holders of Series K Preferred Shares shall not be entitled to any dividend in excess of full cumulative dividends as described above. Any dividend payment made on the Series K Preferred Shares shall first be credited against the earliest accumulated but unpaid dividend due with respect to such shares which remains payable. (g) If, for any taxable year, the Corporation elects to designate as a "capital gain dividend" (as defined in 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 every class or series of stock of the Corporation, the portion of the Capital Gains Amount that shall be allocable to holders of the Series K Preferred Stock shall be the amount that the total dividends (as determined for Federal income tax purposes) paid or made available to the holders of the Series K Preferred Stock for the year bears to the aggregate amount of dividends (as determined for Federal income tax purposes) paid or made available to the holders of all classes or series of stock of the Corporation for such year. (4) LIQUIDATION PREFERENCE. (a) In the event of any voluntary or involuntary liquidation, dissolution or winding up of the Corporation, the holders of Series K Preferred Shares then outstanding shall be entitled to 5 receive out of the assets of the Corporation legally available for distribution to its stockholders remaining after payment or provision for payment of all debts and liabilities of the Corporation, a liquidation preference in cash of $50.00 per share, plus an amount equal to any accumulated or accrued and unpaid dividends to the date of such payment, before any distribution of assets is made to holders of Common Stock or any other equity securities of the Corporation that rank junior to the Series K Preferred Shares as to liquidation rights. (b) If, upon any such voluntary or involuntary liquidation, dissolution or winding up of the Corporation, the assets of the Corporation are insufficient to make full payment to holders of Series K Preferred Shares and the corresponding amounts payable on all shares of other classes or series of equity securities of the Corporation ranking on a parity with the Series K Preferred Shares as to liquidation rights (including the Series A Preferred Stock, the Series B Preferred Stock, the Series D Preferred Stock, the Series E Preferred Stock, the Series F Preferred Stock, the Series G Preferred Stock, the Series H Preferred Stock, the Series I Preferred Stock and the Series J Preferred Stock), then the holders of the Series K Preferred Shares and all other such classes or series of equity securities shall share ratably in any such distribution of assets in proportion to the full liquidating distributions to which they would otherwise be respectively entitled. (c) Written notice of any such liquidation, dissolution or winding up of the Corporation, stating the payment date or dates when, and the place or places where, the amounts distributable in such circumstances shall be payable, shall be given by first class mail, postage pre-paid, not less than 30 nor more than 60 days prior to the payment date stated therein, to each record holder of the Series K Preferred Shares at the respective addresses of such holders as the same shall appear on the stock transfer records of the Corporation. (d) After payment of the full amount of the liquidating distributions to which they are entitled, the holders of Series K Preferred Shares will have no right or claim to any of the remaining assets of the Corporation. (e) The consolidation or merger of the Corporation with or into any other entity, a merger of another entity with or into the Corporation, a statutory share exchange by the Corporation or a sale, lease, transfer or conveyance of all or substantially all of the property or business of the Corporation shall not be deemed to constitute a liquidation, dissolution or winding up of the Corporation. (f) In determining whether a distribution (other than upon voluntary or involuntary liquidation, dissolution or winding up of the Corporation) by dividend, redemption or other acquisition of shares of stock of the Corporation or otherwise is permitted under the MGCL, no effect shall be given to amounts that would be needed, if the Corporation were to be dissolved at the time of the distribution, to satisfy the preferential rights upon dissolution of holders of the Series K Preferred Shares whose preferential rights upon dissolution are superior to those receiving the distribution. 6 (5) OPTIONAL REDEMPTION. (a) The Series K Preferred Shares are not redeemable prior to April 17, 2007. To ensure that the Corporation remains a qualified REIT for Federal income tax purposes, however, the Series K Preferred Shares shall be subject to the provisions of Section 7 of this Article Third pursuant to which Series K Preferred Shares owned by a stockholder in excess of the Ownership Limit (as defined in Section 7 of this Article Third) or certain other limitations shall automatically be transferred to a Trust for the benefit of a Charitable Beneficiary (as defined in Section 7 of this Article Third) and the Corporation shall have the right to purchase such shares, as provided in Section 7 of this Article Third. On and after April 17, 2007, the Corporation, at its option, upon giving notice as provided below, may redeem the Series K Preferred Shares, in whole or from time to time in part, for cash, at a redemption price of $50.00 per share, plus all accumulated and unpaid dividends on such Series K Preferred Shares to the date fixed for redemption. (b) The redemption price of the Series K Preferred Shares (other than any portion thereof consisting of accumulated and unpaid dividends) is payable solely from the sale proceeds of other equity securities of the Corporation, and not from any other source. For purposes of the preceding sentence, "equity securities" means any equity securities (including Common Stock and Preferred Stock (as defined in the Charter), depositary shares in respect of any of the foregoing, 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. (c) If fewer than all of the outstanding Series K Preferred Shares are to be redeemed, the shares to be redeemed shall be selected pro rata (as nearly as practicable without creating fractional shares). (d) Notwithstanding anything to the contrary contained herein, unless full cumulative dividends on all Series K 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 for all past dividend periods and the then current dividend period, no Series K Preferred Shares shall be redeemed unless all outstanding Series K Preferred Shares are simultaneously redeemed; provided, however, that the foregoing shall not prevent the purchase by the Corporation of Series K Preferred Shares pursuant to Section 7 of this Article Third or otherwise in order to ensure that the Corporation remains qualified as a REIT for Federal or state income tax purposes or the purchase or acquisition of Series K Preferred Shares pursuant to a purchase or exchange offer made on the same terms to holders of all outstanding Series K Preferred Shares. In addition, unless full cumulative dividends on all outstanding Series K Preferred Shares have been or contemporaneously are declared and paid or declared and a sum sufficient for the payment thereof irrevocably set apart in trust for payment for all dividend periods, the Corporation shall not purchase or otherwise acquire directly or indirectly any Series K Preferred Shares or any equity securities of the Corporation ranking junior to or on a parity with the Series K Preferred Shares as to dividends or upon voluntary or involuntary liquidation, dissolution or winding up of the Corporation (including the Series A Preferred Stock, the Series B Preferred Stock, the Series D Preferred Stock, the Series E Preferred Stock, the Series F Preferred Stock, the Series G Preferred Stock, the Series H Preferred Stock, the Series I Preferred Stock and the Series J Preferred Stock) (except by conversion into or exchange for equity securities of the Corporation ranking junior to the Series K Preferred Shares as to dividends and upon voluntary or involuntary 7 liquidation, dissolution or winding up of the Corporation and except pursuant to Section 7 of this Article Third or comparable Charter provisions with respect to other classes or series of the Corporation's stock). (e) The holders of shares of Series K Preferred Stock at the close of business on a Dividend Record Date will be entitled to receive the dividend payable with respect to the shares of Series K Preferred Stock held on the corresponding Dividend Payment Date notwithstanding the redemption thereof between such Dividend Record Date and the corresponding Dividend Payment Date or the Corporation's default in the payment of the dividend due. Except as provided herein, the Corporation will make no payment or allowance for unpaid dividends, whether or not in arrears, on Series K Preferred Shares to be redeemed. (f) The following provisions set forth the procedures for Redemption: (i) 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. A similar notice will be (i) faxed and (ii) mailed by the Corporation, postage prepaid, not less than 30 nor more than 60 days prior to the redemption date, addressed to the respective holders of record of the Series K Preferred Shares to be redeemed at their respective addresses as they appear on the share records of the Corporation. 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 K Preferred Shares except as to the holder to whom notice was defective or not given. (ii) In addition to any information required by law or by the applicable rules of any exchange upon which the Series K 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 K Preferred Shares to be redeemed; (D) the place or places where the certificates evidencing shares of Series K Preferred Shares are to be surrendered for payment of the redemption price; and (E) that dividends on the Series K Preferred Shares to be redeemed will cease to accumulate on such redemption date. If fewer than all of the Series K Preferred Shares held by any holder are to be redeemed, the notice mailed to such holder shall also specify the number of Series K Preferred Shares to be redeemed from such holder. (iii) On or after the redemption date, each holder of Series K Preferred Shares to be redeemed shall present and surrender the certificates representing such holder's Series K Preferred Shares to the Corporation at the place designated in the notice of redemption and shall be entitled to the redemption price and any accrued or accumulated and unpaid dividends payable upon such redemption upon such surrender and thereupon the redemption price of such shares (including all accumulated and unpaid dividends up to the redemption date) shall be paid to or on the order of the person whose name appears on such certificate representing Series K Preferred Shares as the owner thereof and each surrendered certificate shall be canceled. If fewer than all the shares represented by any such certificate representing Series K Preferred Shares are to be redeemed, a new certificate shall be issued representing the unredeemed shares. (iv) If notice of redemption of any Series K Preferred Shares has been given and if the funds necessary for such redemption have been irrevocably set aside by the 8 Corporation in trust for the benefit of the holders thereof, then from and after the redemption date all dividends on such Series K Preferred Shares shall cease to accumulate and any such Series K Preferred Shares will no longer be deemed outstanding and all rights of the holders thereof will terminate, except the right to receive the redemption price (including all accrued or accumulated and unpaid dividends up to the redemption date) and such shares shall not thereafter be transferred (except with the consent of the Corporation) on the Corporation's stock transfer records. At its election, the Corporation, prior to a redemption date, may irrevocably deposit the redemption price (including accumulated and unpaid dividends to the redemption date) of the Series K Preferred Shares so called for redemption in trust for the holders thereof with a bank or trust company, in which case the redemption notice to holders of the Series K Preferred Shares to be redeemed shall (A) state the date of such deposit, (B) specify the office of such bank or trust company as the place of payment of the redemption price and (C) require such holders to surrender the certificates representing such shares at such place on or about the date fixed in such redemption notice (which may not be later than the redemption date) against payment of the redemption price (including all accrued or accumulated and unpaid dividends to the redemption date). Any monies so deposited which remain unclaimed by the holders of the Series K Preferred Shares at the end of two years after the redemption date shall be returned by such bank or trust company to the Corporation. (g) Any Series K Preferred Shares that shall at any time have been redeemed shall, after such redemption, have the status of authorized but unissued Preferred Stock, without further designation as to series or class until such shares are once more designated as part of a particular series or class by the Board. (6) VOTING RIGHTS. (a) Holders of the Series K Preferred Shares will not have any voting rights, except as set forth below. (b) (i) Whenever dividends on any Series K Preferred Shares shall remain unpaid for six or more quarterly periods (whether or not consecutive) (a "Preferred Dividend Default"), the holders of such Series K Preferred Shares (voting as a single class with all other equity securities of the Corporation ranking on a parity with the Series K Preferred Shares as to dividends and upon voluntary or involuntary liquidation, dissolution or winding up of the Corporation upon which like voting rights have been conferred and are exercisable, including the Series A Preferred Stock, the Series B Preferred Stock, the Series D Preferred Stock, the Series E Preferred Stock, the Series F Preferred Stock, the Series G Preferred Stock, the Series H Preferred Stock, the Series I Preferred Stock and the Series J Preferred Stock ("Parity Preferred Stock")) will be entitled to vote for the election of two additional directors of the Corporation (the "Preferred Stock Directors"), who will be elected by a plurality of the votes cast in such election for a one-year term and until their successors are duly elected and shall qualify (or until such director's right to hold such office terminates as provided herein, whichever occurs earlier, subject to such director's earlier death, disqualification, resignation or removal), at a special meeting called by the holders of at least 20% of the outstanding Series K Preferred Shares or the holders of shares of any other class or series of Parity Preferred Stock with respect to which dividends are so unpaid (unless such request is received less than 90 days before the date fixed for the next annual or special meeting of stockholders) or, if the request for a special meeting is 9 received by the Corporation less than 90 days before the date fixed for the next annual or special meeting of stockholders, at the next annual or special meeting of stockholders, and at each subsequent annual meeting until all dividends accumulated on the Series K Preferred Shares for all past dividend periods and the dividend for the then current dividend period shall have been fully paid or declared and a sum sufficient for the payment thereof irrevocably set aside in trust for payment in full. (ii) At any time when the voting rights described in Section 6(b)(i) above shall have vested, a proper officer of the Corporation shall call or cause to be called, a special meeting of the holders of Series K Preferred Stock and all the series of Parity Preferred Stock upon which like voting rights have been conferred and are exercisable (collectively, the "Parity Securities") by mailing or causing to be mailed to such holders a notice of such special meeting to be held not less than ten and not more than 45 days after the date such notice is given. The record date for determining holders of the Parity Securities entitled to notice of and to vote at such special meeting will be the close of business on the third business day preceding the day on which such notice is mailed. At any such special meeting, all of the holders of the Parity Securities, by plurality vote, voting together as a single class without regard to series will be entitled to elect two directors on the basis of one vote per $25.00 of liquidation preference to which such Parity Securities are entitled by their terms (excluding amounts in respect of accumulated and unpaid dividends) and not cumulatively. Notice of all meetings at which holders of the Series K Preferred Shares shall be entitled to vote will be given to such holders at their addresses as they appear in the transfer records. If a Preferred Dividend Default shall terminate after the notice of a special meeting has been given but before such special meeting has been held, the Corporation shall, as soon as practicable after such termination, mail or cause to be mailed notice of such termination to holders of the Series K Preferred Shares that would have been entitled to vote at such special meeting. (c) If and when all accumulated dividends and the dividend for the then current dividend period on the Series K Preferred Shares shall have been paid in full or declared by the Corporation and irrevocably set aside in trust for payment in full, the holders of Series K Preferred Shares shall be divested of the voting rights set forth in Section 6(b) of this Article Third (subject to revesting in the event of each and every Preferred Dividend Default) and, if all accumulated dividends have been paid in full or declared by the Corporation and irrevocably set aside in trust for payment in full on all other classes or series of Parity Preferred Stock upon which like voting rights have been conferred and are exercisable, the term of office of each Preferred Stock Director so elected shall forthwith terminate.

The Corporation shall have the right to accept such offer until the Trustee has sold the shares of Series K Preferred Stock held in the Trust pursuant to Section 7(c)(iv). Upon such a sale to the Corporation, the interest of the Charitable Beneficiary in the shares of Series K Preferred 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 the Trustee with respect to such Series K Preferred Stock shall thereupon be paid to the Charitable Beneficiary. (vi) 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 the Series K Preferred Stock held in the Trust would not violate the restrictions set forth in Section 7(b)(i) in the hands of such Charitable Beneficiary. (d) 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 7(b) of these Articles Supplementary 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 Series K Preferred Stock of the Corporation in violation of Section 7(b) of these Articles Supplementary, the Board of Directors or a committee thereof or other designees if permitted by the MGCL shall take such action as it deems advisable to refuse to give effect or to prevent such Transfer, including, but not limited to, causing the Corporation to redeem shares of Series K Preferred Stock, refusing to give effect to such Transfer on the books of the Corporation or instituting proceedings to enjoin such Transfer; 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 7(b)(i) of these Articles Supplementary, shall automatically result in the transfer to a Trust as described in Section 7(b)(ii) and any Transfer in violation of Section 7(b)(iii) shall automatically be void ab initio irrespective of any action (or non-action) by the Board of Directors.

(f) Owners Required To Provide Information. Prior to the Restriction Termination Date each Person who is a beneficial owner or Beneficial Owner or Constructive Owner of Series K Preferred Stock and each Person (including the shareholder of record) who is holding Series K Preferred Stock for a beneficial owner or Beneficial Owner or Constructive Owner shall provide to the Corporation such information that the Corporation may request, in good faith, in order to determine the Corporation's status as a REIT. 17 (g) Remedies Not Limited. Nothing contained in these Articles Supplementary (but subject to Section 7(n) of these Articles Supplementary) 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 by preservation of the Corporation's status as a REIT. (h) Ambiguity. In the case of an ambiguity in the application of any of the provisions of this Section 7 of these Articles Supplementary, including any definition contained in Section 7(a), the Board of Directors shall have the power to determine the application of the provisions of this Section 7 with respect to any situation based on the facts known to it (subject, however, to the provisions of Section 7(n) of these Articles Supplementary). In the event Section 7 requires an action by the Board of Directors and these Articles Supplementary fail to 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 Section 7. 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 7(b)) acquired Beneficial or Constructive Ownership of Series K Preferred Stock in violation of Section 7(b)(i), such remedies (as applicable) shall apply first to the shares of Series K Preferred Stock which, but for such remedies, would have been actually owned by such Person, and second to shares of Series K Preferred 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 Series K Preferred Stock based upon the relative number of the shares of Series K Preferred Stock held by each such Person. (i) Exceptions. (i) Subject to Section 7(b)(i)(C), the Board of Directors, in its sole discretion, may exempt a Person from the limitation on a Person Beneficially Owning shares of Series K Preferred Stock in violation of Section 7(b)(i)(A) if the Board of Directors obtains any representations and undertakings from such Person as are reasonably necessary in the opinion of the Board of Directors to ascertain that no individual's Beneficial Ownership of such shares of Series K Preferred Stock will violate Section 7(b)(i)(A) or that any such violation will not cause the Corporation to fail to qualify as a REIT under the Code, and that any violation of any representations or undertakings (or other action which is contrary to the restrictions contained in Section 7(b) of these Articles Supplementary) or attempted violation will result in such Series K Preferred Stock being transferred to a Trust in accordance with Section 7(b)(ii) of these Articles Supplementary. (ii) Subject to Section 7(b)(i)(C), the Board of Directors, in its sole discretion, may exempt a Person from the limitation on a Person Constructively Owning Series K Preferred Stock in violation of Section 7(b)(i)(B), if the Corporation obtains such representations and undertakings from such Person as are reasonably necessary in the opinion of the Board of Directors to ascertain 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 and that any violation or attempted violation will result in such Series K Preferred Stock being transferred to a Trust in accordance with Section 7(b)(ii) of these Articles Supplementary. Notwithstanding the 18 foregoing, the inability of a Person to make the certification described in this Section 7(i)(ii) shall not prevent the Board of Directors, in its sole discretion, from exempting such Person from the limitation on a Person Constructively Owning Series K Preferred Stock in violation of Section 7(b)(i)(B) if the Board of Directors determines that the resulting application of Section 856(d)(2)(B) of the Code would affect the characterization of less than 0.5% of the gross income (as such term is used in Section 856(c)(2) of the Code) of the Corporation in any taxable year, after taking into account the effect of this sentence with respect to all other capital stock of the Corporation to which this sentence applies. (iii) Prior to granting any exception pursuant to Section 7(i)(i) or (ii) of these Articles Supplementary, the Board of Directors may require a ruling from the Internal Revenue Service, 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.
