         (c) Except as defined below, capitalized terms in this Section 6.1 have
the meanings specified in Section 9.1 of Article IX. For purposes of this
Section 6.1:

               (i) "Change of Control" of (A) the Corporation shall mean any
          transaction or series of related transactions (whether by purchase of
          existing shares of Common Stock or Units, merger, consolidation or
          otherwise, but not including the issuance of newly issued shares of
          Common Stock by the Corporation or of Units by the Operating
          Partnership following a capital contribution by the Corporation in
          response to such issuance by the Corporation), to which the
          Corporation is a party or the Corporation's consent or approval is
          required, the result of which is that either (1) any Person or Group
          becomes the Beneficial Owner, directly or indirectly, of 25% or more
          of the total voting power in the aggregate of all classes of stock of
          the Corporation then outstanding normally entitled to vote in the
          election of Directors of the Corporation (or any surviving entity)
          (including in such calculation the shares of stock such Person or
          Group would receive if any Units owned by such Person or Group were
          presented for redemption and acquired by the Corporation for shares of
          stock) or (2) the Beneficial Owners of the stock of the Corporation
          normally entitled to vote in the election of Directors immediately
          prior to the transaction or series of related transactions
          beneficially own less than 75% of the total voting power in the
          aggregate of all classes of stock of the Corporation then outstanding
          normally entitled to vote in the election of Directors of the
          Corporation (or any surviving entity) immediately after such
          transaction or transactions (including in such calculation the shares
          of stock such Beneficial Owners would receive if any Units owned by
          such Beneficial Owners were presented for redemption and acquired by
          the Corporation for shares of stock); or (B) the Operating Partnership
          shall mean (i) any sale, transfer or other conveyance (whether by
          merger or consolidation of the Corporation or otherwise) by the
          Corporation of the general partnership interest in the Operating
          Partnership, or (ii) any transaction or series of related transactions
          (whether by purchase of existing Units, issuance of Units (other than
          as a result of a capital contribution by the Corporation following an
          issuance of shares of Equity Stock), merger, consolidation or
          otherwise), to which the Operating Partnership is a party or the
          consent or approval of the Corporation is required, the result of
          which is that either (1) any Person or Group becomes the Beneficial
          Owner, directly or indirectly, of Units which represent 25% or more of
          the total percentage of limited partnership interests therein or (2)
          the Beneficial Owners of limited partnership interests therein
          immediately prior to the transaction beneficially own less than 75% of
          the total percentage of limited partnership interests therein then
          outstanding immediately after such transaction or series of related
          transactions.

                  (ii) "Person" shall have the same meaning as such term has for
         purposes of Sections 13(d) and 14(d) of the Exchange Act.


                                       5



                  (iii) "Group" shall have the same meaning as such term has for
         purposes of Sections 13(d) and 14(d) of the Exchange Act.

                  (iv) "Beneficial Owner" shall have the same meaning as such
         term has for purposes of Rule 13d-3 promulgated under the Exchange Act,
         except that a Person shall be deemed to have beneficial ownership of
         all shares that a Person has the right to acquire, whether or not such
         right is immediately exercisable. "Beneficially Owns" and "Beneficially
         Owned" shall have the correlative meanings.

                  (v) "Units" shall mean the units into which partnership
         interests in the Operating Partnership are divided, and as the same may
         be adjusted, as provided in the limited partnership agreement of the
         Operating Partnership (the "Operating Partnership Agreement");
         provided, however, that for the purposes of these Articles the term
         "Units" shall not include the Incentive Units or Convertible Units (as
         such terms are defined in the Operating Partnership Agreement).

         6.2 Number. The number of Directors initially shall be five (5).
Thereafter, the number of Directors shall be as fixed by resolution duly adopted
from time to time by the Board of Directors; provided, however, that the total
number of Directors shall be not fewer than the minimum number required by the
Maryland General Corporation Law and not more than nine (9). No reduction in the
number of Directors shall cause the removal of any Director from office prior to
the expiration of his or her term.

         6.3      Initial Board.  The names of the initial Directors are:

                  Alan M. Leventhal
                  Lionel P. Fortin
                  Stephen T. Clark
                  Steven Shulman
                  Scott M. Sperling

         6.4 Term; Election. The Directors, including the Independent Directors
(as defined below in Section 6.7), shall be classified, with respect to the term
for which they severally hold office, into three classes, as nearly equal in
number as possible. The initial Class I Directors of the Corporation shall be
Alan M. Leventhal; the initial Class II Directors of the Corporation shall be
Lionel P. Fortin and Stephen T. Clark; and the initial Class III Directors of
the Corporation shall be Steven Shulman and Scott M. Sperling. The initial Class
I Directors shall serve for a term expiring at the annual meeting of
stockholders to be held in 1999; the initial Class II Directors shall serve for
a term expiring at the annual meeting of stockholders to be held in 2000; and
the initial Class III Directors shall serve for a term expiring at the annual
meeting of stockholders to be held in 2001. At each annual meeting of
stockholders, the successor or successors of the class of Directors whose term
expires at that meeting shall be elected by a plurality of the votes of the
shares present in person or 


                                       6



represented by proxy at such meeting and entitled to vote on the election of
Directors, and shall hold office for a term expiring at the annual meeting of
stockholders held in the third year following the year of their election. The
Directors elected to each class shall hold office until their successors are
duly elected and qualified or until their earlier resignation or removal.

         Notwithstanding the foregoing, whenever, pursuant to the provisions of
Article VII of these Articles, the holders of any one or more series of
Preferred Stock shall have the right, voting separately as a series or together
with holders of other such series, to elect Directors at an annual or special
meeting of stockholders, the election, term of office, filling of vacancies and
other features of such directorships shall be governed by the terms of these
Articles and any articles supplementary applicable thereto, and such Directors
so elected shall not be divided into classes pursuant to this Section 6.4.

         During any period when the holders of any series of Preferred Stock
have the right to elect additional Directors as provided for or fixed pursuant
to the provisions of Article VII of these Articles, then upon commencement and
for the duration of the period during which such right continues: (a) the
then otherwise total authorized number of Directors of the Corporation shall
automatically be increased by such specified number of Directors, and the
holders of such Preferred Stock shall be entitled to elect the additional
Directors so provided for or fixed pursuant to said provisions and (b) each such
additional Director shall serve until such Director's successor shall have been
duly elected and qualified, or until such Director's right to hold such office
terminates pursuant to said provisions, whichever occurs earlier, subject to
such Director's earlier death, disqualification, resignation or removal. Except
as otherwise provided by the Board in the resolution or resolutions establishing
such series, whenever the holders of any series of Preferred Stock having such
right to elect additional Directors are divested of such right pursuant to the
provisions of such stock, the terms of office of all such additional Directors
elected by the holders of such stock, or elected to fill any vacancies resulting
from the death, resignation, disqualification or removal of such additional
Directors, shall forthwith terminate and the total authorized number of
Directors of the Corporation shall be reduced accordingly.

         6.5 Resignation or Removal of Directors. Any Director may resign from
the Board of Directors or any committee thereof at any time by written notice to
the Board of Directors, effective upon execution and delivery to the Corporation
of such notice or upon any future date specified in the notice. Subject to the
rights, if any, of the holders of any series of Preferred Stock to elect
Directors and to remove any Director whom such holders have the right to elect,
any Director (including persons elected by Directors to fill vacancies in the
Board of Directors) may be removed from office (a) only with cause and (b) only
by the affirmative vote of the holders of at least 75% of the shares then
entitled to vote at a meeting of the stockholders called for that purpose. At
least 30 days prior to any meeting of stockholders at which it is proposed that
any Director be removed from office, written notice of such proposed removal
shall be sent to the Director whose removal will be considered at the 


                                       7



meeting. For purposes of these Articles, "cause," with respect to the removal of
any Director, shall mean only (i) conviction of a felony, (ii) declaration of
unsound mind by order of a court, (iii) gross dereliction of duty, (iv)
commission of any act involving moral turpitude or (v) commission of an act that
constitutes intentional misconduct or a knowing violation of law if such action
in either event results both in an improper substantial personal benefit to such
Director and a material injury to the Corporation.

         6.6 Vacancies. Subject to the rights, if any, of the holders of any
series of Preferred Stock to elect Directors and to fill vacancies in the Board
of Directors relating thereto, any and all vacancies in the Board of
Directors, however occurring, including, without limitation, by reason of an
increase in size of the Board of Directors, or the death, resignation,
disqualification or removal of a Director, shall be filled solely by the
affirmative vote of a majority of the remaining Directors then in office, even
if less than a quorum of the Board of Directors; provided that any Director
appointed to fill the vacancy for an Independent Director shall also require the
vote of a majority of the Independent Directors. Any Director appointed in
accordance with the preceding sentence shall hold office for the remainder of
the full term of the class of Directors in which the new directorship was
created or the vacancy occurred and until such Director's successor shall have
been duly elected and qualified or until such Director's earlier resignation or
removal. Subject to the rights, if any, of the holders of any series of
Preferred Stock, when the number of Directors is increased or decreased, the
Board of Directors shall determine the class or classes to which the increased
or decreased number of Directors shall be apportioned; provided, however, that
no decrease in the number of Directors shall shorten the term of any incumbent
Director. In the event of a vacancy in the Board of Directors, the remaining
Directors, except as otherwise provided by law, may exercise the powers of the
full Board of Directors until such vacancy is filled.

         6.7 Independent Directors. Notwithstanding anything herein to the
contrary, at all times (except during a period not to exceed sixty (60) days
following the death, resignation, incapacity, or removal from office of a
Director prior to the expiration of the Director's term of office), a majority
of the Board of Directors shall be comprised of persons ("Independent
Directors") who are not officers or employees of the Corporation or any
affiliate thereof and who do not have a material business or professional
relationship with the Corporation or any affiliate thereof. The foregoing
provision may not be amended, altered, changed or repealed without the
affirmative vote of two-thirds of the shares of stock of the Corporation then
outstanding and entitled to vote on such matter at a meeting of stockholders.

         6.8 Powers. Subject to the express limitations herein or in the Bylaws,
the business and affairs of the Corporation shall be managed under the direction
of the Board of Directors. These Articles, as amended or supplemented from time
to time, shall be construed with a presumption in favor of the grant of power
and authority to the Directors. The determination as to any of the following
matters, made in good faith by or pursuant to the direction of the Board of
Directors consistent with these Articles and in the absence of actual receipt of
an improper benefit in money, property or services or active and deliberate


                                       8



dishonesty established by a court, shall be final and conclusive and shall be
binding upon the Corporation and every holder of shares of its stock: the amount
of the net income of the Corporation for any period and the amount of assets at
any time legally available for the payment of dividends, redemption of its stock
or the payment of other distributions on its stock; the amount of paid-in
surplus, net assets, other surplus, annual or other net profit, net assets in
excess of capital, undivided profits or excess of profits over losses on sales
of assets; the amount, purpose, time of creation, increase or decrease,
alteration or cancellation of any reserves or charges and the propriety thereof
(whether or not any obligation or liability for which such reserves or charges
shall have been created shall have been paid or discharged); the fair value, or
any sale, bid or asked price to be applied in determining the fair value, of any
asset owned or held by the Corporation; any matters relating to the acquisition,
holding and disposition of any assets by the Corporation; or any other matter
relating to the business and affairs of the Corporation.


                                   ARTICLE VII

                                      STOCK

         7.1 Authorized Stock. The total number of shares of stock which the
Corporation has authority to issue (the "Stock") is nine hundred fifty million
(950,000,000) shares, initially consisting of (i) two hundred million
(200,000,000) shares of preferred stock, par value $.01 per share ("Preferred
Stock"); (ii) five hundred million (500,000,000) shares of common stock, par
value $.01 per share ("Common Stock"); and (iii) two hundred fifty million
(250,000,000) shares of excess stock, par value $.01 per share ("Excess Stock").
The aggregate par value of all the shares of all classes of stock is $9,500,000.
If shares of one class of Stock are classified or reclassified into shares of
another class of Stock pursuant to this Article VII, the number of authorized
shares of the former class shall be automatically decreased and the number of
shares of the latter class shall be automatically increased, in each case by the
number of shares so classified or reclassified, so that the aggregate number of
shares of Stock of all classes that the Corporation has authority to issue shall
not be more than the total number of shares of stock set forth in the first
sentence of this paragraph. To the extent permitted by Maryland law, the Board
of Directors, without any action by the stockholders of the Corporation, may
amend the charter from time to time to increase or decrease the aggregate number
of shares of Stock or the number of shares of Stock of any class or series that
the Corporation has authority to issue.

         7.2 Preferred Stock. Subject to any limitations prescribed by law, the
Board of Directors is expressly authorized to classify any unissued shares of
Preferred Stock and reclassify any previously classified but unissued shares of
Preferred Stock of any series from time to time, in one or more classes or
series of such stock and, by filing articles supplementary with the State
Department of Assessments and Taxation of Maryland, to establish or change from
time to time the number of shares to be included in each such class or


                                       9



series, and to fix the preferences, conversion or other rights, voting powers,
restrictions, limitations as to dividends and other distributions,
qualifications and terms and conditions of redemption of each class or series.
Any action by the Board of Directors under this Section 7.2 of Article VII shall
require the affirmative vote of a majority of the Directors then in office (or,
if a committee shall be acting on behalf of the Board of Directors, a majority
of the members of such committee then in office, which committee was established
by the affirmative vote of a majority of the Directors then in office).

         7.3 Common Stock. Subject to all of the rights, powers and preferences
of the Preferred Stock and except as provided by law or in this Article VII (or
in any articles supplementary regarding any class or series of Preferred Stock):

                  7.3.1 Voting Rights. The holders of shares of Common Stock
         shall be entitled to vote for the election of Directors and on all
         other matters requiring stockholder action, and each holder of shares
         of Common Stock shall be entitled to one vote for each share of Common
         Stock held by such stockholder.

                  7.3.2 Dividend Rights. Holders of Common Stock shall be
         entitled to receive such dividends and other distributions in cash,
         stock or property of the Corporation as may be authorized and declared
         by the Board of Directors upon the Common Stock and, if any Excess
         Stock is then outstanding, the Excess Stock out of any assets or funds
         of the Corporation legally available therefor, but only when and as
         authorized by the Board of Directors or any authorized committee
         thereof from time to time, and shall share ratably with the holders of
         Excess Stock in any such dividend or distribution.

                  Before payment of any dividends or other distributions, there
         may be set aside out of any assets of the Corporation available for
         dividends or other distributions such sum or sums as the Board of
         Directors may from to time, in its absolute discretion, think proper as
         a reserve fund for contingencies, for equalizing dividends or other
         distributions, for repairing or maintaining any property of the
         Corporation or for such other purpose as the Board of Directors shall
         determine to be in the best interest of the Corporation, and the Board
         of Directors may modify or abolish any such reserve in the manner in
         which it was created.

                  7.3.3 Rights Upon Liquidation. Upon the voluntary or
         involuntary liquidation, dissolution or winding up of the Corporation,
         the net assets of the Corporation available for distribution to the
         holders of Common Stock, and, if any Excess Stock is then outstanding,
         Excess Stock shall be distributed pro rata to such holders in
         proportion to the number of shares of Common Stock and Excess Stock
         held by each.


                                       10



         7.4 Excess Stock. For the purposes of this Section 7.4, terms not
otherwise defined shall have the meanings set forth in Article IX.

                  7.4.1    Conversion into Excess Stock.

                           (a) If, notwithstanding the other provisions
                  contained in these Articles, from and after the date of the
                  Offering and prior to the Restriction Termination Date, there
                  is a purported Transfer or Non-Transfer Event such that any
                  Person (other than a Look- Through Entity) would Beneficially
                  Own shares of Equity Stock in excess of the Ownership Limit,
                  or such that any Person that is a Look-Through Entity would
                  Beneficially Own shares of Equity Stock in excess of the
                  Look-Through Limit, then, (i) except as otherwise provided in
                  Section 9.4 of Article IX, the purported transferee shall be
                  deemed to be a Prohibited Owner and shall acquire no right or
                  interest (or, in the case of a Non-Transfer Event, the Person
                  holding record title to the shares of Equity Stock
                  Beneficially Owned by such Beneficial Owner shall cease to own
                  any right or interest) in such number of shares of Equity
                  Stock which would cause such Beneficial Owner to Beneficially
                  Own shares of Equity Stock in excess of the Ownership Limit or
                  the Look-Through Limit, as the case may be, (ii) such number
                  of shares of Equity Stock in excess of the Ownership Limit or
                  the Look-Through Limit, as the case may be, (rounded up to the
                  nearest whole share) shall be automatically converted into an
                  equal number of shares of Excess Stock and transferred to a
                  Trust in accordance with Section 7.4.4 of this Article VII and
                  (iii) the Prohibited Owner shall submit the certificates
                  representing such number of shares of Equity Stock to the
                  Corporation, accompanied by all requisite and duly executed
                  assignments of transfer thereof, for registration in the name
                  of the Trustee of the Trust. Such conversion into Excess Stock
                  and transfer to a Trust shall be effective as of the close
                  of trading on the Trading Day prior to the date of the
                  purported Transfer or Non-Transfer Event, as the case may be,
                  even though the certificates representing the shares of Equity
                  Stock so converted may be submitted to the Corporation at a
                  later date.

                           (b) If, notwithstanding the other provisions
                  contained in these Articles, from and after the date of the
                  Offering and prior to the Restriction Termination Date there
                  is a purported Transfer or Non-Transfer Event that, if
                  effective, would (i) result in the Corporation being "closely
                  held" within the meaning of Section 856(h) of the Code, (ii)
                  cause the Corporation to Constructively Own 10% or more of the
                  ownership interest in a tenant of the Corporation's or a
                  Subsidiary's real property within the meaning of Section
                  856(d)(2)(B) of the Code or (iii) result in the shares of
                  Equity Stock being beneficially owned by fewer than 100
                  persons within the meaning of Section 856(a)(5) of the Code,
                  then (x) the purported transferee shall be deemed to be a


                                       11



                  Prohibited Owner and shall acquire no right or interest 
                  (or, in the case of a Non-Transfer Event, the Person 
                  holding record title of the shares of Equity Stock with 
                  respect to which such Non-Transfer Event occurred shall 
                  cease to own any right or interest) in such number of 
                  shares of Equity Stock, the ownership of which by such 
                  purported transferee or record holder would (A) result in 
                  the Corporation being "closely held" within the meaning of 
                  Section 856(h) of the Code, (B) cause the Corporation to 
                  Constructively Own 10% or more of the ownership interests 
                  in a tenant of the Corporation's or a Subsidiary's real 
                  property within the meaning of Section 856(d)(2)(B) of the 
                  Code or (c) result in the shares of Equity Stock being 
                  beneficially owned by fewer than 100 persons within the 
                  meaning of Section 856(a)(5) of the Code, (y) such number 
                  of shares of Equity Stock (rounded up to the nearest whole 
                  share) shall be automatically converted into an equal 
                  number of shares of Excess Stock and transferred to a Trust 
                  in accordance with Section 7.4 of this Article VII and (z) 
                  the Prohibited Owner shall submit such number of shares of 
                  Equity Stock to the Corporation, accompanied by all 
                  requisite and duly executed assignments of transfer 
                  thereof, for registration in the name of the Trustee of the 
                  Trust. Such conversion into Excess Stock and transfer to a 
                  Trust shall be effective as of the close of trading on the 
                  Trading Day prior to the date of the purported Transfer or 
                  Non-Transfer Event, as the case may be, even though the 
                  certificates representing the shares of Equity Stock so 
                  converted may be submitted to the Corporation at a later 
                  date.

                           (c) Upon the occurrence of such a conversion of
                  shares of Equity Stock into an equal number of shares of
                  Excess Stock, such shares of Equity Stock shall be
                  automatically retired and canceled, without any action
                  required by the Board of Directors of the Corporation, and
                  shall thereupon be restored to the status of authorized but
                  unissued shares of the particular class or series of Equity
                  Stock from which such Excess Stock was converted and may be
                  reissued by the Corporation as that particular class or series
                  of Equity Stock.

                  7.4.2 Remedies for Breach. If the Corporation, or its
         designees, shall at any time determine in good faith that a Transfer
         has taken place in violation of Section 9.2 of Article IX or that a
         Person intends to acquire or has attempted to acquire Beneficial
         Ownership or Constructive Ownership of any shares of Equity Stock in
         violation of Section 9.2 of Article IX, the Corporation shall take such
         action as it deems advisable to refuse to give effect to or to prevent
         such Transfer or acquisition, including, but not limited to, refusing
         to give effect to such Transfer on the stock transfer books of the
         Corporation or instituting proceedings to enjoin such Transfer or
         acquisition, but the failure to take any such action shall not affect
         the automatic conversion of shares of Equity Stock into Excess Stock
         and their transfer to a Trust in accordance with Section 7.4.1.


                                       12



                  7.4.3 Notice of Restricted Transfer. Any Person who acquires
         or attempts to acquire shares of Equity Stock in violation of Section
         9.2 of Article IX, or any Person who owns shares of Equity Stock that
         were converted into shares of Excess Stock and transferred to a Trust
         pursuant to Sections 7.4.1 and 7.4.4 of this Article VII, 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 Non-Transfer Event, as the case may be, on the
         Corporation's status as a REIT.

                  7.4.4 Ownership in Trust. Upon any purported Transfer or Non-
         Transfer Event that results in Excess Stock pursuant to Section 7.4.1
         of this Article VII, (i) the Corporation shall create, or cause to be
         created, a Trust, and shall designate a Trustee and name a Beneficiary
         thereof and (ii) such Excess Stock shall be automatically transferred
         to such Trust to be held for the exclusive benefit of the Beneficiary.
         Any conversion of shares of Equity Stock into shares of Excess Stock
         and transfer to a Trust shall be effective as of the close of trading
         on the Trading Day prior to the date of the purported Transfer or
         Non-Transfer Event that results in the conversion. Shares of Excess
         Stock so held in trust shall remain issued and outstanding shares of
         stock of the Corporation.

                  7.4.5 Dividend Rights. Each share of Excess Stock shall be
         entitled to the same dividends and distributions (as to both timing and
         amount) as may be declared by the Board of Directors with respect to
         shares of Common Stock. The Trustee, as record holder of the shares of
         Excess Stock, shall be entitled to receive all dividends and
         distributions and shall hold all such dividends or distributions in
         trust for the benefit of the Beneficiary. The Prohibited Owner with
         respect to such shares of Excess Stock shall repay to the Trust the
         amount of any dividends or distributions received by it that are (i)
         attributable to any shares of Equity Stock that have been converted
         into shares of Excess Stock and (ii) dividends or distributions which
         were distributed by the Corporation to stockholders of record on a
         record date which was on or after the date that such shares were
         converted into shares of Excess Stock. The Corporation shall take all
         measures that it determines reasonably necessary to recover the amount
         of any such dividend or distribution paid to a Prohibited Owner,
         including, if necessary, withholding any portion of future dividends or
         distributions payable on shares of Equity Stock Beneficially Owned by
         the Person who, but for the provisions of Articles VII and IX, would
         Constructively Own or Beneficially Own the shares of Equity Stock that
         were converted into shares of Excess Stock; and, as soon as reasonably
         practicable following the Corporation's receipt or withholding thereof,
         shall pay over to the Trust for the benefit of the Beneficiary the
         dividends so received or withheld, as the case may be.

                  7.4.6 Rights upon Liquidation. In the event of any voluntary
         or involuntary liquidation of, or winding up of, or any distribution of
         the assets of, the Corporation, 


                                       13



         each holder of shares of Excess Stock shall be entitled to receive,
         ratably with each other holder of shares of Common Stock and Excess
         Stock, that portion of the assets of the Corporation that is available
         for distribution to the holders of Common Stock and Excess Stock. The
         Trust shall distribute to the Prohibited Owner the amounts received
         upon such liquidation, dissolution, or winding up, or distribution;
         provided, however, that the Prohibited Owner shall not be entitled to
         receive amounts in excess of, in the case of a purported Transfer in
         which the Prohibited Owner gave value for shares of Equity Stock and
         which Transfer resulted in the conversion of the shares into shares of
         Excess Stock, the product of (x) the price per share, if any, such
         Prohibited Owner paid for the shares of Equity Stock and (y) the
         number of shares of Equity Stock which were so converted into Excess
         Stock, and, in the case of a Non-Transfer Event or purported Transfer
         in which the Prohibited Owner did not give value for such shares
         (e.g., if the shares were received through a gift or devise) and which
         Non-Transfer Event or purported Transfer, as the case may be, resulted
         in the conversion of the shares into shares of Excess Stock, the
         product of (x) the price per share equal to the Market Price on the
         date of such Non-Transfer Event or purported Transfer and (y) the
         number of shares of Equity Stock which were so converted into Excess
         Stock. Any remaining amount in such Trust shall be distributed to the
         Beneficiary.

                  7.4.7 Voting Rights. Each share of Excess Stock shall entitle
         the holder to no voting rights other than those voting rights which
         accompany a class of stock under Maryland law. The Trustee, as record
         holder of the Excess Stock, shall be entitled to vote all shares of
         Excess Stock. Any vote by a Prohibited Owner as a purported holder of
         shares of Equity Stock prior to the discovery by the Corporation that
         such shares of Equity Stock have been converted into shares of Excess
         Stock shall, subject to applicable law, (i) be rescinded and shall be
         void ab initio with respect to such shares of Excess Stock and (ii) be
         recast in accordance with the desires of the Trustee acting for the
         benefit of the 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.


                  7.4.8    Designation of Permitted Transferee.

                  (a) As soon as practicable after the Trustee acquires Excess
Stock, but in an orderly fashion so as not to materially adversely affect the
trading price of Common Stock, the Trustee shall designate one or more Persons
as Permitted Transferees and sell to such Permitted Transferees any shares of
Excess Stock held by the Trustee; provided, however, that (i) any Permitted
Transferee so designated purchases for valuable consideration (whether in a
public or private sale) the shares of Excess Stock and (ii) any Permitted
Transferee so designated may acquire such shares of Excess Stock without
violating any of the restrictions set forth in Section 9.2 of Article IX and
without such acquisition resulting in the conversion of the shares of Equity
Stock so acquired into shares of Excess Stock and the transfer of such


                                       14



shares to a Trust pursuant to Sections 7.4.1 and 7.4.4 of this Article VII. The
Trustee shall have the exclusive and absolute right to designate Permitted
Transferees of any and all shares of Excess Stock. Prior to any transfer by the
Trustee of shares of Excess Stock to a Permitted Transferee, the Trustee shall
give not less than five Trading Days' prior written notice to the Corporation of
such intended transfer and the Corporation must have waived in writing its
purchase rights under Section 7.4.10 of this Article VII.

                  (b) Upon the designation by the Trustee of a Permitted
Transferee in accordance with the provisions of this Section 7.4.8, the Trustee
shall cause to be transferred to the Permitted Transferee shares of Excess Stock
acquired by the Trustee pursuant to Section 7.4.4 of this Article VII. Upon such
transfer of shares of Excess Stock to the Permitted Transferee, such shares of
Excess Stock shall be automatically converted into an equal number of shares of
Equity Stock of the same class and series from which such Excess Stock was
converted. Upon the occurrence of such a conversion of shares of Excess Stock
into an equal number of shares of Equity Stock, such shares of Excess Stock
shall be automatically retired and canceled, without any action required by the
Board of Directors of the Corporation, and shall thereupon be restored to the
status of authorized but unissued shares of Excess Stock and may be reissued by
the Corporation as Excess Stock. The Trustee shall (i) cause to be recorded on
the stock transfer books of the Corporation that the Permitted Transferee is the
holder of record of such number of shares of Equity Stock, and (ii) distribute
to the Beneficiary any and all amounts held with respect to such shares of
Excess Stock after making payment to the Prohibited Owner pursuant to Section
7.4.9 of this Article VII.

                  (c) If the Transfer of shares of Excess Stock to a purported
Permitted Transferee would or does violate any of the transfer restrictions set
forth in Section 9.2 of Article IX, such Transfer shall be void ab initio as to
that number of shares of Excess Stock that cause the violation of any such
restriction when such shares are converted into shares of Equity Stock (as
described in clause (b) above) and the purported Permitted Transferee shall be
deemed to be a Prohibited Owner and shall acquire no rights in such shares of
Excess Stock or Equity Stock. Such shares of Equity Stock shall be automatically
re-converted into Excess Stock and transferred to the Trust from which they were
originally Transferred. Such conversion and transfer to the Trust shall be
effective as of the close of trading on the Trading Day prior to the date of the
Transfer to the purported Permitted Transferee and the provisions of this
Article VII shall apply to such shares, including, without limitation, the
provisions of Sections 7.4.8 through 7.4.10 with respect to any future Transfer
of such shares by the Trust.

                  7.4.9 Compensation to Record Holder of Shares of Equity Stock
         That Are Converted into Shares of Excess Stock. Any Prohibited Owner
         shall be entitled (following acquisition of the shares of Excess Stock
         and subsequent designation of and sale of Excess Stock to a Permitted
         Transferee in accordance with Section 7.4.8 of this Article VII or
         following the acceptance of the offer to purchase such shares in
         accordance with Section 7.4.10 of this Article VII) to receive from the
         Trustee following the sale or other disposition of such shares of
         Excess Stock the lesser of (i) 


                                       15



         (a) in the case of a purported Transfer in which the Prohibited Owner
         gave value for shares of Equity Stock and which Transfer resulted in
         the conversion of such shares into shares of Excess Stock, the product
         of (x) the price per share, if any, such Prohibited Owner paid for the
         shares of Equity Stock and (y) the number of shares of Equity Stock
         which were so converted into Excess Stock and (b) in the case of a
         Non-Transfer Event or purported Transfer in which the Prohibited Owner
         did not give value for such shares (e.g., if the shares were received
         through a gift or devise) and which Non-Transfer Event or purported
         Transfer, as the case may be, resulted in the conversion of such
         shares into shares of Excess Stock, the product of (x) the price per
         share equal to the Market Price on the date of such Non-Transfer Event
         or purported Transfer and (y) the number of shares of Equity Stock
         which were so converted into Excess Stock or (ii) the proceeds
         received by the Trustee from the sale or other disposition of such
         shares of Excess Stock in accordance with Section 7.4.8 or Section
         7.4.10 of this Article VII. Any amounts received by the Trustee in
         respect of such shares of Excess Stock and in excess of such amounts
         to be paid to the Prohibited Owner pursuant to this Section 7.4.9
         shall be distributed to the Beneficiary in accordance with the
         provisions of Section 7.4.8 of this Article VII. Each Beneficiary and
         Prohibited Owner shall waive any and all claims that it may have
         against the Trustee and the Trust arising out of the disposition of
         shares of Excess Stock, except for claims arising out of the gross
         negligence or willful misconduct of, or any failure to make payments
         in accordance with this Section 7.4 of this Article VII by such
         Trustee.

                  7.4.10 Purchase Right in Excess Stock. Shares of Excess Stock
         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 shares of Excess Stock (or,
         in the case of a Non-Transfer Event or Transfer in which the Prohibited
         Owner did not give value for the shares (e.g., if the shares were
         received through a gift or devise), the Market Price on the date of
         such Non-Transfer Event or Transfer in which the Prohibited Owner did
         not give value for the shares) or (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 90 days following
         the later of (a) the date of the Non-Transfer Event or purported
         Transfer which results in such shares of Excess Stock or (b) the date
         the Board of Directors first determined that a Transfer or Non-Transfer
         Event resulting in shares of Excess Stock has occurred, if the
         Corporation does not receive a notice of such Transfer or Non-Transfer
         Event pursuant to Section 7.4.3 of this Article VII.

         7.5 Classification of Stock. The Board of Directors may classify or
reclassify any unissued shares of Stock from time to time by setting or changing
the preferences, conversion or other rights, voting powers, restrictions,
limitations as to dividends and other distributions, qualifications, and terms
and conditions of redemption for each class or series, including, but not
limited to, the reclassification of unissued shares of Common Stock to shares of
Preferred 


                                       16



Stock or unissued shares of Preferred Stock to shares of Common Stock or the
issuance of any rights plan or similar plan.

         7.6 Issuance of Stock. The Board of Directors may authorize the
issuance from time to time of shares of Stock of any class or series, whether
now or hereafter authorized, or securities or rights convertible into shares of
Stock, for such consideration as the Board of Directors may deem advisable (or
without consideration in the case of a share split or dividend), subject to such
restrictions or limitations, if any, as may be set forth in these Articles or
the By-laws of the Corporation.

         7.7 Dividends or Distributions. The Directors may from time to time
authorize and declare and pay to stockholders such dividends or distributions in
cash, property or other assets of the Corporation or in securities of the
Corporation or from any other source as the Directors in their discretion shall
determine.

         7.8 Ambiguity. In the case of an ambiguity in the application of any of

are listed or admitted to trading or, if the shares of Equity Stock are not


                                       19



listed or admitted to trading on any national securities exchange, the last
quoted price, or if not so quoted, the average of the high bid and low asked
prices in the over-the-counter market, as reported by the Nasdaq Stock Market,
Inc. or, if such system is no longer in use, the principal other automated

undertakings acceptable to it and subject to the provisions of Article VI, may,
in its sole discretion, waive the application of Section 9.4(a) to a Person
subject, as the case may be, to any such limitations on Transfer, provided that
(A) the Board of Directors obtains such representations and undertakings from
such Person as are reasonably necessary to ascertain that such Person's
Beneficial Ownership or Constructive Ownership of shares of Equity Stock will
now and in the future not result in the Corporation Constructively Owning 10% or
more of the ownership interests in a tenant of the real property of the
Corporation or any direct or indirect Subsidiary of the Corporation, within the
meaning of Section 856(d)(2)(B) of the Code and (B) such Person agrees in

as the Board of Directors may establish at the time of such waiver with respect
to such Person or (y) such other restrictions and conditions as the Board of
Directors may in its sole discretion impose at the time of such waiver with
respect to such Person, will result, as of the time of such violation even if
discovered after such violation, in the conversion of such shares in excess of
the original limit applicable to such Person into shares of Excess Stock
pursuant to Section 7.4.1 of Article VII.

         (b) The Board of Directors, upon receipt of a ruling from the Internal
Revenue Service or an opinion of counsel or other evidence or undertakings
acceptable to it and subject to the provisions of Article VI, may, in its sole
discretion, waive the application of the Ownership Limit or the Look-Through
Ownership Limit to a Person subject, as the case may be, to any such limit,
provided that (A) the Board of Directors obtains such representations and
undertakings from such Person as are reasonably necessary to ascertain that such
Person's Beneficial Ownership or Constructive Ownership of shares of Equity
Stock will now and in the future (i) not result in the Corporation being
"closely held" within the meaning of Section 856(h) of the Code, (ii) not cause
the Corporation to Constructively Own 10% or more of the ownership interests of
a tenant of the Corporation or a Subsidiary within the meaning of Section
856(d)(2)(B) of the Code and to violate the 95% gross income test of Section
856(c)(2) of the Code, and (iii) not result in the shares of Equity Stock of the
Corporation being beneficially owned by fewer than 100 persons within the
meaning of Section 856(a)(5) of the Code and (B) such Person agrees in writing
that any violation or attempted violation of (x) such other limitation as the
Board of Directors may establish at the time of such waiver with respect to such
Person or (y) such other restrictions and conditions as the Board of Directors
may in its sole discretion impose at the time of such waiver with respect to
such Person, will result, as of the time of such violation even if discovered
after such violation, in the conversion of such shares in excess of the original
limit applicable to such Person into shares of Excess Stock pursuant to Section
7.4.1 of Article VII.

         9.5 New York Stock Exchange Transactions. Notwithstanding any provision
contained herein to the contrary, nothing in these Articles shall preclude the
settlement of any transaction entered into through the facilities of the New
York Stock Exchange or any other national securities exchange or the Nasdaq
Stock Market, Inc. or any other automated quotation system. In no event shall
the existence or application of the preceding sentence have the effect of
deterring or preventing the conversion of Equity Stock into Excess Stock as
contemplated herein.

         9.6 Ambiguity. In the case of an ambiguity in the application of any of
the provisions of this Article IX, including any definition contained in Section
9.1 of this Article IX, the Board of Directors shall have the power to determine
the application of the provisions of this Article IX with respect to any
situation based on the facts known to it.

         9.7 Remedies Not Limited. Except as set forth in Section 9.5 of this
Article IX, nothing contained in this Article IX or Article VII shall limit the
authority of the Corporation 


                                       24



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 and to ensure compliance with the Ownership Limit
or the Look-Through Ownership Limit.


                                    ARTICLE X

                        RIGHTS AND POWERS OF CORPORATION,
                         BOARD OF DIRECTORS AND OFFICERS

         In carrying on its business, or for the purpose of attaining or
furthering any of its objects, the Corporation shall have all of the rights,
powers and privileges granted to corporations by the laws of the State of
Maryland, as well as the power to do any and all acts and things that a natural
person or partnership could do as now or hereafter authorized by law, either
alone or in partnership or conjunction with others. In furtherance and not in
limitation of the powers conferred by statute, the powers of the Corporation and
of the Directors and stockholders shall include the following:

         10.1 Conflicts of Interest. Any Director or officer individually, or
any firm of which any Director or officer may be a member, or any corporation or
association of which any Director or officer may be a director or officer or in
which any Director or officer may be interested as the holder of any amount of
its stock or otherwise, may be a party to, or may be pecuniarily or otherwise
interested in, any contract or transaction of the Corporation, and, in the
absence of fraud, no contract or other transaction shall be thereby affected or
invalidated; provided, however, that (a) such fact shall have been disclosed or
shall have been known to the Board of Directors or the committee thereof that
approved such contract or transaction and such contract or transaction shall
have been approved or satisfied by the affirmative vote of a majority of the
disinterested Directors, or (b) such fact shall have been disclosed or shall
have been known to the stockholders entitled to vote, and such contract or
transaction shall have been approved or ratified by a majority of the votes cast
by the stockholders entitled to vote, other than the votes of shares owned of
record or beneficially by the interested Director or corporation, firm or other
entity, or (c) the contract or transaction is fair and reasonable to the
Corporation. Any Director of the Corporation who is also a director or officer
of or interested in such other corporation or association, or who, or the firm
of which he is a member, is so interested, may be counted in determining the
existence of a quorum at any meeting of the Board of Directors of the
Corporation which shall authorize any such contract or transaction, with like
force and effect as if he were not such director or officer of such other
corporation or association or were not so interested or were not a member of a
firm so interested.

         10.2 Amendment of Articles. The Corporation reserves the right, from
time to time, to make any amendment of its Articles, now or hereafter authorized
by law, including any amendment which alters the contract rights, as expressly
set forth in its Articles of any outstanding Stock.


                                       25



         No amendment or repeal of these Articles shall be made unless the same
is first approved by the Board of Directors pursuant to a resolution adopted by
the Board of Directors in accordance with Maryland General Corporation Law, and,
except as otherwise provided by law, thereafter approved by the stockholders.

         Whenever any vote of the holders of voting stock is required to amend
or repeal any provision of these Articles, then in addition to any other vote of
the holders of voting stock that is required by these Articles or by law, the
affirmative vote of a majority of the outstanding shares of stock of the
Corporation entitled to vote on such amendment or repeal, voting together as a
single class, and the affirmative vote of a majority of the outstanding shares
of each class entitled to vote thereon as a class, shall be required to amend or
repeal any provision of these Articles; provided, however, that in each case
two-thirds rather than a majority shall be needed if such amendment or repeal is
not approved by more than 75% of the Directors then in office; and provided,
further, that the affirmative vote of not less than 75% of the outstanding
shares entitled to vote on such amendment or repeal, voting together as a single
class, and the affirmative vote of not less than 75% of the outstanding shares
of each class entitled to vote thereon as a class, shall be required to amend or
repeal any of the provisions of Article VI, Article X or Article XII of these
Articles.

                                  MISCELLANEOUS

         15.1 Provisions in Conflict with Law or Regulations.

                  (a) The provisions of these Articles are severable, and if the
Directors shall determine that any one or more of such provisions are in
conflict with the REIT provisions of the Code, or other applicable federal or
state laws, the conflicting provisions shall be deemed never to have constituted
a part of these Articles, even without any amendment of these Articles pursuant
to Section 10.2 hereof; provided, however, that such determination by the
Directors shall not affect or impair any of the remaining provisions of these
Articles or render invalid or improper any action taken or omitted prior to such
determination. No Director shall be liable for making or failing to make such a
determination.

                  (b) If any provision of these Articles or any application of
such provision shall be held invalid or unenforceable by any federal or state
court having jurisdiction, such holding shall not in any manner affect or render
invalid or unenforceable such provision in any other jurisdiction, and the
validity of the remaining provisions of these Articles shall not be affected.
Other applications of such provision shall be affected only to the extent
necessary to comply with the determination of such court.
