                  Operating Partnership in accordance with their terms, and

                  Partnership is required to obtain any consent, authorization
                  or order of, or make any filing or registration with, any
                  court or governmental agency or any regulatory or
                  self-regulatory agency in order for it to execute, deliver or

                  Principal Market and has no actual knowledge of any facts
                  which would reasonably lead to delisting or suspension of the
                  Common Stock by the Principal Market in the foreseeable
                  future.

                                       11

         a. If as of the Mandatory Closing the Buyer cannot make the
representations of the Buyer called for by the Amended and Restated Ownership
Limit Waiver Agreement or if the Company advises the Buyer in writing that,
after reasonable due diligence conducted in cooperation with the Buyer, the
Company has concluded in good faith that the Tax Conditions (as hereinafter
defined) would not be satisfied, then a portion of the investment to be made by
the Buyer on the Mandatory Closing (the "MANDATORY CLOSING INVESTMENT") shall be
made in Series A-2 Preferred Units (as defined in the Limited Partnership
Agreement of the Operating Partnership, as amended (the "PARTNERSHIP
AGREEMENT")) of the Operating Partnership. Subject to the provisions of the
following sentence, that portion of the Mandatory Closing Investment to be made
in such Series A-2 Preferred Units shall be an amount sufficient to reduce the
Buyer's ownership of the capital stock of the Company to less than 9.9% of the
value of the capital stock of the Company (taking into account any attribution
of the Company's capital stock to the Buyer arising from the Buyer's 10% or
greater shareholders, as determined under Section 318(a) of the Internal Revenue
Code of 1986, as amended (the "Code"), as modified by Section 856(d) of the
Code), such value to be computed utilizing the average closing price of the
Company's Common Stock on the New York Stock Exchange for the ten trading days
ending on the trading day immediately preceding the Mandatory Closing Date and
assuming that the value of the Preferred Shares is equal to the Series A
Conversion Value (as defined in the Certificate of Designations) of such
Preferred Shares. If the Buyer cannot make the representation called for in
Section (a) of the Certificate of Representations and Covenants for Ownership
Limit Waiver attached as Exhibit B to the Amended and Restated Ownership Limit
Waiver Agreement, then the provisions of the immediately preceding sentence
shall apply except that 9.225% shall be substituted for 9.9%. If a portion of
the Mandatory Preferred Investment is to be made in such Series A-2 Preferred
Units, then for each Preferred Share that would otherwise be purchased at the
Mandatory Closing but for the provisions of this Section 13(a), the Buyer shall
purchase in lieu thereof that number of Series A-2 Preferred Units equal to the
quotient of one divided by the Conversion Multiple (as defined in the
Partnership Agreement) (the Company represents and warrants to the Buyer that as
of the date hereof the Conversion Multiple is one). The purchase price of each
Series A-2 Preferred Unit purchased at the Mandatory Closing shall be

         b. If any proposed pledgee or subsequent transferee of Preferred Shares
or Common Shares cannot make the representations called for by the Amended and
Restated Ownership Limit Waiver Agreement or if the Company advises such pledgee
or subsequent transferee in writing that, after reasonable due diligence
conducted in cooperation with such pledgee or subsequent transferee, the Company
has concluded in good faith that the Tax Conditions would not be satisfied,
then, simultaneously with the effectiveness of the pledge or transfer, a portion
of the Preferred Shares to be pledged or transferred to such pledgee or
subsequent transferee shall be contributed to the Operating Partnership in
exchange for Series A-2 Preferred Units in order to reduce such pledgee's or
subsequent transferee's ownership of the capital stock of the Company to less
than 9.9% of the value of the capital stock of the Company (taking into account
any attribution of the Company's capital stock to the pledgee or subsequent
transferee arising from the pledgee's or subsequent transferee's 10% or greater
shareholders, as determined under Section 318(a) of the Code, as modified by
Section 856(d) of the Code), such value to be computed utilizing the average
closing price of the Company's Common Stock on the New York Stock Exchange for
the ten trading days ending on the trading day immediately preceding the date of
the pledge or transfer and assuming that the value of the Preferred Shares is

equal to the Series A Conversion Value of such Preferred Shares as of such date.
If the Buyer cannot make the representation called for in Section (a) of the
Certificate of Representations and Covenants for Ownership Limit Waiver attached
as Exhibit B to the Amended and Restated Ownership Limit Waiver Agreement, then
the provisions of the immediately preceding sentence shall apply except that
9.225% shall be substituted for 9.9%. In any contribution and exchange to be
made pursuant to this Section 13(b), the requisite contribution and exchange
shall be made first of Common Shares being pledged or transferred and then of
Preferred Shares being pledged or transferred. Common Shares shall be exchanged
for Common Units (as defined in the Partnership Agreement) as hereinafter
provided and Preferred Shares shall be exchanged for Series A-2 Preferred Units
as hereinafter provided. For each Common Share that would otherwise be pledged
or transferred, the pledgee or transferee shall receive in lieu thereof that
number of Common Units equal to the quotient of one divided by the Conversion
Multiple then in effect. For each Preferred Share that would otherwise be
pledged or transferred, the pledgee or transferee shall receive in lieu thereof
that number of Series A-2 Preferred Units equal to the quotient of one divided
by the Conversion Multiple then in effect.

         c. If at any time there would have been, but for the application of the
remedies set forth herein, a violation of one or more of the Tax Conditions,
then without any action on the part of either the holders of the Preferred
Shares or the Common Shares or the Company or the Operating Partnership, a
number of Preferred Shares or Common Shares, as applicable, shall automatically
be contributed to the Operating Partnership in exchange for Series A-2 Preferred
Units or Common Units, as applicable, in an amount sufficient to prevent the
violation of the Tax Conditions from occurring and effective as of the close of
business on the business day prior to the first day on which the Tax Conditions
would not have been satisfied but for such contribution and exchange. In any
contribution to be made pursuant to this Section 13(c), the requisite
contribution shall be made first of Common Shares prior to any contribution of
Preferred Shares. If the exchange involves Series A Preferred Shares, the
exchange shall be effected through a contribution of the Series A Preferred
Shares to the Operating Partnership in exchange for Series A-2 Preferred Units
(with the result that the Operating Partnership would become an owner of Series
A Preferred Shares). The Operating Partnership and the Company shall then
convert such Series A Preferred Shares into Common Stock and the Operating
Partnership shall retain such Common Stock at least until the holder of the
Series A-2 Preferred Units issued in exchange for the contribution of such
Series A Preferred Shares has disposed of those Series A-2 Preferred Units. In
any event, the exchange of the Series A Preferred Shares for Series A-2
Preferred Units, and any redemption proceeds, conversion, distributions or other
payments made thereafter on the Series A Preferred Shares contributed to the
Operating Partnership or on any Common Stock into which they were converted by
the Partnership, shall not be included in any calculations relating to dividends
or other payments due to holders of Series A Preferred Shares other than the
Operating Partnership. For each Common Share to be exchanged, such holder shall
receive that number of Common Units equal to the quotient of one divided by the
Conversion Multiple then in effect. For each Preferred Share to be exchanged,
the holder shall receive in lieu thereof that number of Series A-2 Preferred
Units equal to the quotient of one divided by the Conversion Multiple then in
effect. Such exchange shall be effective as of the close of business on the
business day prior to the first day on which the Tax Conditions would not have
been satisfied but for such exchange.

         d. Each holder of Preferred Shares shall have the right to exchange all
or any portion of the Preferred Shares for Series A-2 Preferred Units for any
reason at any time and from time to time. Any exchange described herein would be
effected in the manner described in the following paragraph (e).

         e. In no event and under no circumstances (other than in the event of
fraud with respect to the Certificate (as defined in the Amended and Restated
Ownership Limit Waiver Agreement) or the breach of the representation with
respect to direct ownership of tenants under Section 2.5 of the Amended and
Restated Ownership Limit Waiver Agreement, in each case as determined by a
final, non-appealable judgment of a court of competent jurisdiction) shall any
of the Series A Preferred Shares, the Series A-2 Preferred Units or securities
issued or issuable upon conversion or exchange thereof become "Excess Stock" as
defined in the Charter while held by the Buyer or a Subsequent Holder to which
the Ownership Limit Waiver in the Amended and Restated Ownership Limit Waiver
Agreement applies. If any of the conditions to the effectiveness of the
Ownership Limit Waiver is violated by any Person, there shall be an automatic
exchange, with an effective date as of the day prior to the event giving rise to
such violation, of Series A Preferred Shares for Series A-2 Preferred Units (or
Common Shares into Common Units, as applicable) in an amount sufficient to keep
the Ownership Limit Waiver in effect. The exchange shall occur by operation of
law without the requirement for any action on the part of any party. If the
exchange involves Series A Preferred Shares, the exchange shall be effected
through a contribution of the Series A Preferred Shares to the Operating
Partnership in exchange for Series A-2 Preferred Units (with the result that the
Operating Partnership would become an owner of Series A Preferred Shares). The
Operating Partnership and the Company shall then convert such Series A Preferred
Shares into Common Stock and the Operating Partnership shall retain such Common
Stock at least until the holder of the Series A-2 Preferred Units issued in
exchange for the contribution of such Series A Preferred Shares has disposed of
those Series A-2 Preferred Units. In any event, the exchange of the Series A
Preferred Shares for Series A-2 Preferred Units, and any redemption proceeds,
conversion, distributions or other payments made thereafter on the Series A
Preferred Shares contributed to the Operating Partnership or on any Common Stock
into which it is converted by the Partnership, shall not be included in any
calculations relating to dividends or other payments due to holders of Series A
Preferred Shares other than the Operating Partnership. In any contribution to be
made pursuant to this Section 13(e), the requisite contribution shall be made
first of Common Shares prior to the contribution of Preferred Shares. For each
Common Share to be exchanged, such holder shall receive that number of Common
Units equal to the quotient of one divided by the Conversion Multiple then in
effect. For each Preferred Share to be exchanged, the holder shall receive in
lieu thereof that number of Series A-2 Preferred Units equal to the quotient of
(i) the Series A Conversion Value then in effect divided by the Series A
Conversion Price then in effect divided by (ii) the Conversion Multiple then in
effect. Such exchange shall be effective as of the close of business on the
business day prior to the first day on which the Tax Conditions would not have
been satisfied but for such exchange.

         f. Intentionally omitted.

         g. The Company and the Operating Partnership shall promptly take all
action or actions necessary to keep the Conversion Multiple at one and to insure
that each Series A


                                       14
<PAGE>

Preferred Share has the same economic value, rights and interest as the Series
A-2 Preferred Units, and neither the Company nor the Operating Partnership shall
take any action that would change the Conversion Multiple to something other
than 1.

         h.       As used herein, the term "Tax Conditions" shall mean the
                  following:

         1.       The Acquisition (as defined in the Charter) and Beneficial
                  Ownership (as defined in the Charter) of Preferred Shares
                  and/or Common Shares by the Buyer or any Subsequent Holder (as
                  defined in the Ownership Limit Waiver Agreement) permitted by
                  reason of the Ownership Limit Waiver (as defined in the
                  Ownership Limit Waiver Agreement) shall not and is not
                  reasonably expected to cause the Company to be considered to
                  own for purposes of Section 856(d)(2)(B), applying the
                  applicable constructive ownership rules, an interest in any
                  one or more tenants of the Company and its subsidiaries that
                  is described in Section 856(d)(2)(B) of the Code and from
                  which the Company derives, in the aggregate, more than 0.5% of
                  its gross income for any calendar year.

         2.       The Acquisition and Beneficial Ownership of Preferred Shares
                  and/or Common Shares by Buyer or any Subsequent Holder
                  permitted by reason of the Ownership Limit Waiver shall not
                  and is not reasonably expected to cause the Company to fail to
                  qualify as a "domestically-controlled REIT" within the meaning
                  of Section 897(h)(2) of the Code.

         3.       The Acquisition and Beneficial Ownership of Preferred Shares
                  and/or Common Shares permitted by reason of the Ownership
                  Limit Waiver shall not and will not cause any individual
                  (within the meaning of Section 542(a)(2) of the Code,
                  determined taking into account Section 856(h)(3)(A) of the
                  Code) to be considered to have Beneficial Ownership of
                  Company's stock that violates the Ownership Limit, as
                  increased by the Board pursuant to Section 12.9 of the
                  Charter).

         SECTION 12. ADDITION OF SECTION 14 TO THE SECURITIES PURCHASE
AGREEMENT. A new Section 14 is added to the Securities Purchase Agreement to
read in its entirety as follows:

         "14. PROVISIONS REGARDING INTERNAL RATE OF RETURN CALCULATIONS AND
PAYMENT OF PURCHASE PRICE OF MANDATORY PREFERRED SHARES.

         (a) For purposes of accounting for and calculating payments made, or to
be made, by the Company on the Preferred Shares and by the Operating Partnership
on the Series A-2 Preferred Units that involve a determination of an Internal
Rate of Return (as defined in the Certificate of Designations), the provisions
of this Section 14 shall apply. For any such determination, it shall be assumed
that there are twelve (12) periods in each year, which shall be each calendar
month of each such year, and that each such period shall end on the last day of
each such calendar month. In the event a payment by the Company or the Operating
Partnership to which this Section 14 applies is received by the Buyer on or
before the fifth (5th) Business Day


                                       15
<PAGE>

of a period, such payment shall be deemed to have been received by the Buyer on
the last day of the previous period. In the event a payment by the Company or
the Operating Partnership to which this Section 14 applies is received by the
Buyer after the fifth (5th) Business Day but before the last day of such period,
such payment shall be deemed to have been received by the Buyer on the last day
of the previous period, provided that in addition to any amount due to the Buyer
in connection with such payment as of the end of the previous period, Buyer
shall be entitled to also be paid an amount equal to the applicable Internal
Rate of Return on the Stated Liquidation Value (as defined in the Certificate of
Designations) for the number of days such payment is made after the end of the
previous period.

         (b) The payment of the Purchase Price for the Preferred Shares and/or
Series A-2 Preferred Units purchased by the Buyer at the Initial Closing and the
Mandatory Closing shall be deemed to have been paid on April 30, 2001 and May
31, 2001, respectively. For purposes of the first assumption contained in the
definition of "Internal Rate of Return" in the Certificate of Designations, the
Mandatory Closing shall be deemed to have occurred on May 31, 2001. At the
Mandatory Closing, the Buyer shall be credited with having paid to the Company
as part of the Purchase Price an aggregate amount equal to an annual rate of
[CONFIDENTIAL TREATMENT REQUESTED]*% (i.e., the difference between the
[CONFIDENTIAL TREATMENT REQUESTED]*% Internal Rate of Return and the
[CONFIDENTIAL TREATMENT REQUESTED]*% Regular Dividend Rate to be paid during
the first anniversary of the initial issuance of the Preferred Shares)
multiplied by the Purchase Price otherwise to be paid by the Buyer at the
Mandatory Closing for the number of days between the day of the Mandatory
Closing and the end of the period during which the Mandatory Closing occurs,
and the actual amount to be paid by the Buyer to the Company at the Mandatory
Closing shall be the Purchase Price less such credit, provided that for
purposes of all computations of or involving Internal Rate of Return under
the Certificate of Designations, this Agreement and the other Transaction
Documents, Buyer shall be treated as having paid the full Purchase Price.

         (b) The preceding paragraphs (a) and (b) shall be deemed a part of the
sample calculations attached as exhibits to this Agreement."

         SECTION 13. REFERENCE TO AND EFFECT ON THE SECURITIES PURCHASE
AGREEMENT. Except as amended hereby, the Securities Purchase Agreement remains
in full force and effect and is hereby ratified and confirmed.

         SECTION 14. EXECUTION IN COUNTERPARTS. This Amendment may be executed
in two counterparts, each of which when so executed and delivered shall be
deemed to be an original and both of which taken together shall constitute one
and the same instrument.

         SECTION 15. HEADINGS. Section headings in this Amendment are included
herein for convenience of reference only and shall not constitute a part of this
Amendment for any other purpose.

         SECTION 16. EFFECTIVENESS. This Amendment will become effective after a
counterpart to this Amendment have been executed by the Company, the Operating
Partnership and the Buyer and the documents described in Section 1 hereof have
been executed by the Company, the Operating Partnership and the Buyer.
