================================================================================


         The person identified in this Prospectus, whom we refer to as the
"Selling Shareholder," may use this Prospectus to offer and sell up to 3,679,245
of our Common Shares of beneficial interest from time to time. We are
registering these Common Shares for offer and sale as required under the terms
of a registration rights agreement between the Selling Shareholder and us. Our
registration of the offered Common Shares does not mean that the Selling
Shareholder will offer or sell any of the Common Shares. We will receive no
proceeds of any sales of the offered Common Shares by the Selling Shareholder,
but we will incur expenses in connection with the offering.

         The Selling Shareholder may sell the offered Common Shares in public or
private transactions, on or off the New York Stock Exchange, at prevailing
market prices or at privately negotiated prices. The Selling Shareholder may
sell the offered Common Shares directly or through agents or broker-dealers
acting as principal or agent, or in a distribution by underwriters.

         Our Common Shares are listed on the New York Stock Exchange under the
trading symbol "BDN."

         To assist us in qualifying as a real estate investment trust for
federal income tax purposes, our Declaration of Trust provides that, without an
exemption, no shareholder or group of affiliated shareholders may own more than
9.8% in value of our outstanding Common Shares.

         Investing in the offered Common Shares involves risks. You should
carefully read the risk factors described in this Prospectus and in our Annual
Report on Form 10-K filed on March 27, 2003, which is incorporated by reference
in this Prospectus.

         This Prospectus is part of a registration statement on Form S-3 that we
filed with the Securities and Exchange Commission under the Securities Act of
1933. This Prospectus and any accompanying Prospectus supplement do not contain
all of the information included in the registration statement. For further
information, we refer you to the registration statement, including its exhibits,
filed with the SEC. Statements contained in this Prospectus and any accompanying
Prospectus supplement about the contents of any document are not necessarily
complete. If SEC rules require that a document be filed as an exhibit to the
registration statement, please see such document for a complete description of
these matters. You should not assume that the information in this Prospectus or
any Prospectus supplement is accurate as of any date other than the date on the
front of each document.

         This Prospectus provides you with a general description of the offered
Common Shares. Each time the Selling Shareholder sells any of the offered Common
Shares to you, the Selling Shareholder will provide you with this Prospectus and
a Prospectus supplement, if applicable, that will contain specific information
about the terms of the offering. The Prospectus supplement also may add, update
or change any information contained in this Prospectus. You should read both
this Prospectus and any Prospectus supplement together with additional
information described under the heading "Where You Can Find More Information"
below.

         The registration statement of which this Prospectus is a part includes
an additional Prospectus and serves to register an additional 4,875,000 of our
Common Shares. The person identified as the selling shareholder in the
additional Prospectus may use the additional Prospectus to offer and sell up to
all of such additional Common Shares from time to time.

                           FORWARD-LOOKING STATEMENTS

         Some of the information included or incorporated by reference in this
Prospectus contains forward-looking statements, including statements that are
not historical or factual. We intend these forward-looking statements to be
covered by the safe harbor provisions for forward-looking statements contained
in the Private Securities Litigation Reform Act of 1995 and we are including
this paragraph for purposes of complying with these safe harbor provisions. The
forward-looking statements include statements regarding our intent, belief or
expectations. You can identify these statements by the use of terminology such
as "may," "will," "expect," "believe," "intend," "plan," "estimate," "should"
and other comparable terms. In addition, we, through our senior management, from
time to time make forward-looking oral and written public statements concerning
our expected future operations and other developments.

         Although forward-looking statements reflect our good faith beliefs and
best judgment based upon current information, they are not guarantees of future
performance and are subject to known and unknown risks and uncertainties. Actual
results may differ materially from the expectations contained in the
forward-looking statements as a result of various factors. Such factors include,
but are not limited to, the risks identified under the caption "Risk Factors" in
our Annual Report on Form 10-K for the year ended December 31, 2002.

                                  RISK FACTORS

         You should carefully consider the "Risk Factors" in our Annual Report
on Form 10-K for the fiscal year ended December 31, 2002 before deciding to
invest in our Common Shares.

                INFORMATION ABOUT US and the selling shareholder

General

         We, Brandywine Realty Trust, were formed in 1986 as a Maryland real
estate investment trust, or REIT. We are self-administered and self-managed and
engage in acquiring, developing, redeveloping, leasing and managing office and
industrial properties located predominantly in the Mid-Atlantic region. We
operate in a manner intended to qualify as a REIT under the Internal Revenue
Code.

         At September 30, 2003, we owned a portfolio of 207 office properties,
25 industrial facilities and one mixed-use property that contained an aggregate
of approximately 16.0 million net rentable square feet. At September 30, 2003,
we also owned approximately 425 acres of undeveloped land. In addition, at
September 30, 2003, we held economic interests in 10 real estate ventures formed
with third parties to develop commercial properties. We own all of our assets
through our interest in Brandywine Operating Partnership, L.P. (the "Operating
Partnership").

         Our executive offices are located at 401 Plymouth Road, Plymouth
Meeting, Pennsylvania 19462 and our telephone number is (610) 325-5600. We have
an internet web address at http://www.brandywinerealty.com. Information included
or referred to on our website is not a part of this prospectus.

Selling Shareholder

         In 1998 and 1999, the Operating Partnership issued 1,950,000 of its
Series B Preferred Units of limited partnership interest to Commonwealth
Atlantic Operating Properties Inc. (the "Selling Shareholder") and certain of
its affiliates in exchange for interests in real estate and real estate-related
assets. As of the date of this Prospectus, the Selling Shareholder owns all of
the Series B Preferred Units. Each Series B Preferred Unit has a stated value of
$50.00 and is convertible into Class A Units at a conversion price of $28.00;
provided that if the average market price of our Common Shares during the
60-trading day period ending on December 31, 2003 is $23.00 or lower, the
conversion price declines to $26.50. Each Class A Unit may be tendered by the
holder to the Operating Partnership for cash equal to the fair market value of a
Common Share at the time of redemption. At our option, we may purchase the Class
A Units for cash equal to the value of an equivalent number of Common Shares or
we may redeem the Class A Units for an equivalent number of Common Shares and
become the owner of the redeemed Class A Units.

                                      -3-



         We issued the Series B Units in reliance upon the exemption from the
registration requirements of the Securities Act set forth in Section 4(2) of
such statute. In the transaction, we agreed to file a registration statement
with the SEC covering the resale of the Common Shares issuable to the Selling
Shareholder upon the conversion of the Class A Units received upon conversion of
the Series B Preferred Units, and to indemnify the Selling Shareholder against
claims made against it arising out of, among other things, statements made in
the registration statement. Accordingly, we are registering, and this Prospectus
relates to, the offer and sale by the Selling Shareholder of the Common Shares
to be received by the Selling Shareholder upon the conversion, in whole or in
part, of the Series B Preferred Units into Class A Units and the conversion of
the Class A Units into Common Shares. The registration of these securities does
not necessarily mean that any of these securities will be offered or sold by the
Selling Shareholder. We have agreed to pay all expenses of this registration.

                                 USE OF PROCEEDS

         We will not receive any proceeds from the sale of the Common Shares
covered by this Prospectus. All of the net proceeds from the sale of the Common
Shares will go to the Selling Shareholder.







                                      -4-




                  DESCRIPTION OF SHARES OF BENEFICIAL INTEREST

         The following paragraphs summarize provisions of our shares of
beneficial interest. This is a summary, and does not completely describe our
shares of beneficial interest. For a complete description, we refer you to our
Declaration of Trust and Bylaws.

General

         Our Declaration of Trust provides that we are authorized to issue up to
110,000,000 shares of beneficial interest, referred to in this Prospectus as
Shares, consisting of 100,000,000 Common Shares and 10,000,000 Preferred Shares,
par value $.01 per share. Of the Preferred Shares, 750,000 have been designated
as 7.25% Series A Cumulative Convertible Preferred Shares and are referred to in
this Prospectus as the Series A Preferred Shares. An additional 4,375,000
Preferred Shares have been designated as 8.75% Series B Senior Cumulative
Convertible Preferred Shares and are referred to in this Prospectus as the
Series B Preferred Shares. Our Declaration of Trust may generally be amended by
our Board of Trustees, without shareholder approval, to increase or decrease the
aggregate number of authorized Shares of any class except for the Series A
Preferred Shares and Series B Preferred Shares. The authorized Common Shares and
undesignated Preferred Shares are generally available for future issuance
without further action by our shareholders, unless such action is required by
applicable law, the rules of any stock exchange or automated quotation system on
which our securities may be listed or traded or pursuant to the preferential
rights of the Series A Preferred Shares or Series B Preferred Shares. Holders of
Series A Preferred Shares and Series B Preferred Shares have the right to
approve certain additional issuances of Preferred Shares, such as shares that
would rank senior to the Series A or Series B Preferred Shares as to dividends
or liquidation preference.

         Both Maryland statutory law governing real estate investment trusts
organized under Maryland law (the "Maryland REIT Law") and our Declaration of
Trust provide that none of our shareholders will be personally liable, by reason
of status as a shareholder, for any of our obligations. Our Bylaws further
provide that we will indemnify any shareholder or former shareholder against any
claim or liability to which such shareholder may become subject by reason of
being or having been a shareholder, and that we shall reimburse each shareholder
who has been successful, on the merits or otherwise, in the defense of a
proceeding to which he has been made a party by reason of status as such for all
reasonable expenses incurred by him in connection with any such claim or
liability.

         Our Declaration of Trust provides that, subject to the provisions of
any class or series of Preferred Shares then outstanding and to the mandatory
provisions of applicable law, our shareholders are entitled to vote only on the
following matters: (i) election or removal of trustees; (ii) amendment of the
Declaration of Trust (other than an amendment to increase or decrease the
aggregate number of authorized Shares of any class); (iii) a determination by
the Trust to invest in commodities contracts (other than interest rate futures
intended to hedge us against interest rate risk), engage in securities trading
(as compared to investment) activities or hold properties primarily for sale to
customers in the ordinary course of business; and (iv) our merger with another
entity. Except with respect to these matters, no action taken by our
shareholders at any meeting shall in any way bind our Board of Trustees.

Transfer Agent and Registrar

         The transfer agent and registrar for the Common Shares is currently
EquiServe.

Shares

     Common Shares of Beneficial Interest

         Each outstanding Common Share entitles the holder to one vote on all
matters submitted to a vote of shareholders, including the election of trustees.
There is no cumulative voting in the election of trustees. Subject to (i) the
preferential rights of the Series A Preferred Shares and Series B Preferred
Shares and (ii) such preferential rights as may be granted by our Board of
Trustees in future issuances of additional series of Preferred Shares, holders
of Common Shares are entitled to such distributions as may be authorized and
declared from time to time by our Board of Trustees out of funds legally
available therefor.

                                      -5-



         Holders of Common Shares have no conversion, exchange or redemption
rights or preemptive rights to subscribe to any of our securities. All
outstanding Common Shares are fully paid and nonassessable. In the event of any
liquidation, dissolution or winding-up of our affairs, subject to (i) the
preferential rights of the Series A Preferred Shares and Series B Preferred
Shares and (ii) such preferential rights as may be granted by our Board of
Trustees in connection with the future issuances of additional series of
Preferred Shares, holders of Common Shares will be entitled to share ratably in
any of our assets remaining after provision for payment of liabilities to
creditors. All Common Shares have equal dividend, distribution, liquidation and
other rights.

     Preferred Shares of Beneficial Interest

         The Preferred Shares authorized by our Declaration of Trust may be
issued from time to time in one or more series. Prior to the issuance of
Preferred Shares of each such series, our Board of Trustees is required by the
Maryland REIT Law and our Declaration of Trust to set for each series the terms,
preferences, conversion or other rights, voting powers, restrictions,
limitations as to distributions, qualifications and terms or conditions of
redemption, as are permitted by the Maryland REIT Law. These rights, powers,
restrictions and limitations could include the right to receive specified
distributions and payments on liquidation prior to any such payments being made
to the holders of Common Shares. Under certain circumstances, the issuance of
Preferred Shares could have the effect of delaying, deferring or preventing a
change of control of the Company and may adversely affect the voting and other
rights of the holders of Common Shares. See "Provisions of Maryland Law and of
our Declaration of Trust and Bylaws - Control Share Acquisitions."

         Classification or Reclassification of Preferred Shares

         Our Declaration of Trust authorizes the trustees to classify or
reclassify, in one or more series, any unissued Preferred Shares by setting or
changing the number of Preferred Shares constituting such series and the
designation, preferences, conversion or other rights, voting powers,
restrictions, limitations as to distributions, qualifications or terms or
conditions of redemption of such Preferred Shares.

         Series A Preferred Shares. We currently have 750,000 Series A Preferred
Shares issued and outstanding. Each Series A Preferred Share has a stated value
(the "Stated Value") of $50.00 and is convertible into Common Shares at the
option of the holder at a conversion price (the "Conversion Price") of $28.00.
The Conversion Price will be reduced to $26.50 if the average closing price of
the Common Shares during the 60-trading day period ending on December 31, 2003
is $23.00 or lower. At any time that the average market price of the Common
Shares is equal to or greater than 120% of the Conversion Price for 60
consecutive trading days, we have the right to redeem all or any part of the
outstanding Series A Preferred Shares for an amount in cash equal to the
aggregate Stated Value of the Series A Preferred Shares to be redeemed (plus
accrued and unpaid distributions) or for a number of Common Shares equal to the
aggregate Stated Value of the Series A Preferred Shares to be redeemed divided
by the Conversion Price (plus accrued and unpaid distributions). In addition, at
any time on or after January 2, 2004, we have the right to redeem all or any
part of the outstanding Series A Preferred Shares for an amount in cash equal to
the aggregate Stated Value of the Series A Preferred Shares to be redeemed (plus
accrued and unpaid distributions) or, in the event that the average closing
price of the Common Shares is equal to or greater than 110% of the Conversion
Price for 60 consecutive trading days, for a number of Common Shares equal to
the aggregate Stated Value of the Series A Preferred Shares to be redeemed
divided by the Conversion Price (plus accrued and unpaid distributions). Each
Series A Preferred Share accrues distributions, payable in cash and prior to the
payment of any distribution on the Common Shares, in an amount equal to the
greater of (i) $0.9063 per quarter (equivalent to $3.625 per annum) or (ii) the
cash distributions paid or payable for the most recent quarter on the number of
Common Shares into which a Series A Preferred Share is convertible. The holders
of Series A Preferred Shares have no voting rights except (i) with respect to
actions which would have a material and adverse effect on the rights of such
holders and (ii) in the event quarterly distributions on the Series A Preferred
Shares are in arrears for six or more quarters. In the event the quarterly
distributions are so in arrears, the holders of the Series A Preferred Shares
have the right, voting together as a single class with any other class of our
Preferred Shares ranking on a parity with the Series A Preferred Shares, to
elect two additional members to our Board of Trustees. In the event of any
liquidation, dissolution or winding-up of our affairs, the holders of the Series
A Preferred Shares are entitled to receive from our assets remaining after
provision for payment of liabilities to creditors an amount equal to the
aggregate Stated Value of the Series A Preferred Shares then outstanding
together with any accrued and unpaid distributions thereon prior to the
distribution of any such assets to the holders of the Common Shares.

                                      -6-



         Series B Preferred Shares. We currently have 4,375,000 Series B
Preferred Shares issued and outstanding. Distributions on the Series B Preferred
Shares are cumulative from the date of issuance and are payable quarterly at the
greater of (i) $0.525 per share and (ii) the amount of the quarterly
distribution payable on the number of Common Shares into which a Series B
Preferred Share is convertible. The Series B Preferred Shares rank pari passu as
to distributions with the Series A Preferred Shares. We may not pay
distributions on the Common Shares, or other shares that rank junior to the
Series B Preferred Shares as to distributions, until we have paid distributions
on the Series B Preferred Shares. A holder of a Series B Preferred Share may
convert the share into one Common Share at a conversion price of $24.00 per
Common Share. The liquidation value of each Series B Preferred Share equals
$24.00 plus accrued and unpaid distributions. The Series B Preferred Shares rank
pari passu upon liquidation with the Series A Preferred Shares. At any time on
or after April 19, 2004, we may require the conversion of the Series B Preferred
Shares into Common Shares if the Common Shares have traded, during any
consecutive 90-day period following such date, at a price in excess of 130% of
the conversion price and the Common Shares to be issued are freely transferable
and listed on the New York Stock Exchange. We may redeem all of the outstanding
Series B Preferred Shares at any time on or after April 19, 2007 for $24 per
share plus accrued and unpaid distributions. If we experience a change of
control, become closely-held or a pension-held REIT, or fail to qualify as a
REIT, other than through action of Five Arrows Realty Securities III L.L.C.,
Five Arrows may require us to purchase the outstanding Series B Preferred Shares
for $24.48 per share plus accrued and unpaid distributions. Under certain
circumstances, we may, in lieu of making such payment, revise the conversion
ratio so that, based on the then-current market price of the Common Shares, each
Series B Preferred Share will thereafter be convertible into that number of
Common Shares having an aggregate market value equal to at least $28.80. In
certain transactions involving a merger or consolidation as to which holders of
Series B Preferred Shares have a separate voting right, holders who do not vote
in favor of the transaction may require us to redeem their shares for $24.96 per
share plus accrued and unpaid distributions. Five Arrows has the right to vote
on all matters as a single class with holders of Common Shares, and as a
separate class on certain matters affecting the rights of the Series B Preferred
Shares. So long as Five Arrows beneficially owns at least 50% of the outstanding
Series B Preferred Shares, Five Arrows may appoint one trustee to our Board of
Trustees. If we (i) fail to pay distributions on Common Shares equal to at least
$0.32 for two consecutive quarters, (ii) reduce the annual distribution on our
Common Shares to below $1.28 per share, (iii) fail to pay timely distributions
on the Series B Preferred Shares, (iv) are in material default of our credit
facility or (v) fail to maintain a debt service coverage ratio of at least 1.25
or a debt to market capitalization ratio no higher .70, then Five Arrows will
have the right to appoint a second trustee to our Board.

Restrictions on Transfer

         For us to qualify as a REIT under the Internal Revenue Code, not more
than 50% in value of our outstanding Shares may be owned, directly or
indirectly, by five or fewer individuals (defined in the Internal Revenue Code
to include certain entities such as qualified pension plans) during the last
half of a taxable year and Shares must be beneficially owned by 100 or more
persons during at least 335 days of a taxable year of twelve months (or during a
proportionate part of a shorter taxable year).

         Because our Board of Trustees believes it is at present important for
us to continue to qualify as a REIT, our Declaration of Trust, subject to
certain exceptions, contains provisions that restrict the number of Shares that
a person may own and that are designed to safeguard us against an inadvertent
loss of REIT status. In order to prevent any shareholder from owning Shares in
an amount that would cause more than 50% in value of the outstanding Shares to
be held by five or fewer individuals, our Board of Trustees, pursuant to
authority granted in our Declaration of Trust, has passed a resolution that,
subject to certain exceptions, provides that no person may own, or be deemed to
own by virtue of the attribution provisions of the Internal Revenue Code, more
than 9.8% in value of the outstanding Shares. This limitation is referred to in
this Prospectus as the Ownership Limit. Our Board of Trustees, subject to
limitations, retains the authority to effect additional increases to, or
establish exemptions from, the Ownership Limit. Our Board of Trustees, pursuant
to authority granted in our Declaration of Trust, has passed resolutions that
exempt the initial holders of the Series A Preferred Shares and Series B
Preferred Shares and Cohen & Steers Capital Management, Inc. and related persons
from the Ownership Limit, on the condition that, and for so long as, such
holders comply with certain representations, warranties and agreements intended
to ensure that no direct or indirect owner of any of such holders owns more than
9.8% in value of the outstanding Shares.

         In addition, pursuant to our Declaration of Trust, no purported
transfer of Shares may be given effect if it would result in ownership of all of
the outstanding Shares by fewer than 100 persons (determined without any

                                      -7-



reference to the rules of attribution) or result in our being "closely held"
within the meaning of Section 856(h) of the Internal Revenue Code. These
restrictions are referred to in this Prospectus as the Ownership Restrictions.
In the event of a purported transfer or other event that would, if effective,
result in the ownership of Shares in violation of the Ownership Limit or the
Ownership Restrictions, such transfer would be deemed void and such Shares
automatically would be exchanged for "Excess Shares" authorized by our
Declaration of Trust, according to rules set forth in our Declaration of Trust,
to the extent necessary to ensure that the purported transfer or other event
does not result in the ownership of Shares in violation of the Ownership Limit
or the Ownership Restrictions.

         Holders of Excess Shares are not entitled to voting rights (except to
the extent required by law), dividends or distributions. If, after the purported
transfer or other event resulting in an exchange of Shares for Excess Shares and
prior to the discovery by us of such exchange, dividends or distributions are
paid with respect to Shares that were exchanged for Excess Shares, then such
dividends or distributions would be repayable to us upon demand. While
outstanding, Excess Shares would be held in trust by us for the benefit of the
ultimate transferee of an interest in such trust, as described below. While
Excess Shares are held in trust, an interest in that trust may be transferred by
the purported transferee or other purported holder with respect to such Excess
Shares only to a person whose ownership of the Shares would not violate the
Ownership Limit or the Ownership Restrictions, at which time the Excess Shares
would be exchanged automatically for Shares of the same type and class as the
Shares for which the Excess Shares were originally exchanged. Our Declaration of
Trust contains provisions that are designed to ensure that the purported
transferee or other purported holder of the Excess Shares may not receive in
return for such a transfer an amount that reflects any appreciation in the
Shares for which such Excess Shares were exchanged during the period that such
Excess Shares were outstanding. Any amount received by a purported transferee or
other purported holder in excess of the amount permitted to be received would be
required to be turned over to us.

         Our Declaration of Trust also provides that Excess Shares shall be
deemed to have been offered for sale to us, or our designee, which shall have
the right to accept such offer for a period of 90 days after the later of: (i)
the date of the purported transfer or event which resulted in an exchange of
Shares for such Excess Shares; and (ii) the date our Board of Trustees
determines that a purported transfer or other event resulting in an exchange of
Shares for such Excess Shares has occurred if we do not receive notice of any
such transfer. The price at which we may purchase such Excess Shares would be
equal to the lesser of: (i) in the case of Excess Shares resulting from a
purported transfer for value, the price per share in the purported transfer that
caused the automatic exchange for such Excess Shares or, in the case of Excess
Shares resulting from some other event, the market price of such Shares on the
date of the automatic exchange for Excess Shares; or (ii) the market price of
such Shares on the date that we accept the Excess Shares. Any dividend or
distribution paid to a proposed transferee on Excess Shares prior to the
discovery by us that such Shares have been transferred in violation of the
provisions of our Declaration of Trust shall be repaid to us upon our demand. If
the foregoing restrictions are determined to be void or invalid by virtue of any
legal decision, statute, rule or regulation, then the intended transferee or
holder of any Excess Shares may be deemed, at our option, to have acted as our
agent and on our behalf in acquiring or holding such Excess Shares and to hold
such Excess Shares on our behalf.

         Our trustees may waive the Ownership Restrictions if evidence
satisfactory to the trustees and our tax counsel or tax accountants is presented
showing that such waiver will not jeopardize our status as a REIT under the
Internal Revenue Code. As a condition of such waiver, our trustees may require
that an intended transferee give written notice to us, furnish such
undertakings, agreements and information as may be required by our trustees
and/or an undertaking from the applicant with respect to preserving our status.
Any transfer of Shares, or any security convertible into Shares that would
create a direct or indirect ownership of Shares in excess of the Ownership Limit
or result in the violation of the Ownership Restrictions, will be void with
respect to the intended transferee and will result in Excess Shares as described
above.

         Neither the Ownership Restrictions nor the Ownership Limit will be
removed automatically even if the REIT provisions of the Internal Revenue Code
are changed so as no longer to contain any ownership concentration limitation or
if the ownership concentration limitation is increased. Except as described
above, any change in the Ownership Restrictions would require an amendment to
our Declaration of the Trust. Amendments to our Declaration of Trust generally
require the affirmative vote of holders owning not less than a majority of the
outstanding Shares entitled to vote thereon. In addition to preserving our
status as a REIT, the Ownership Restrictions and the Ownership Limit may have
the effect of precluding an acquisition of control of us without the approval of
our Board of Trustees.

                                      -8-



         All persons who own, directly or by virtue of the applicable
attribution provisions of the Internal Revenue Code, more than 4.0% of the value
of any class of outstanding Shares, must file an affidavit with us containing
the information specified in our Declaration of Trust by January 31 of each
year. In addition, each shareholder shall upon demand be required to disclose to
us in writing such information with respect to the direct, indirect and
constructive ownership of Shares as our trustees deem necessary to comply with
the provisions of the Internal Revenue Code applicable to REITs, to comply with
the requirements of any taxing authority or governmental agency or to determine
any such compliance.

         The Ownership Limit could have the effect of delaying, deferring or
preventing a transaction or a change in our control that might involve a premium
price for the Common Shares or otherwise be in the best interest of our
shareholders.

         All certificates representing Shares that are hereafter issued will
bear a legend referring to the restrictions and limitations described above.

                        PROVISIONS OF MARYLAND LAW AND OF
                       OUR DECLARATION OF TRUST AND BYLAWS

         The following paragraphs summarize provisions of Maryland law, our
Declaration of Trust and our Bylaws. These paragraphs are a summary, and do not
completely describe Maryland law, our Declaration of Trust or our Bylaws. For a
complete description, we refer you to the Maryland statutes applicable to REITs,
our Declaration of Trust and our Bylaws.

Duration

         Under our Declaration of Trust, we have a perpetual term of existence
and will continue perpetually subject to the authority of our Board of Trustees
to terminate our existence and liquidate our assets and subject to termination
pursuant to the Maryland REIT Law.

Board of Trustees

         Our Declaration of Trust provides that the number of our trustees shall
not be less than three nor more than 15. Any vacancy, including a vacancy
created by an increase in the number of trustees, may be filled by a majority of
our trustees.

         Our trustees generally will each serve for a one-year term. In
connection with a transaction that included issuance of the Series B Preferred
Units, we granted to an affiliate of the Selling Shareholder the right to
designate an individual for election to the Board. We have also granted to the
holders of Series B Preferred Shares a right to elect a trustee as well as the
right to elect an additional trustee if we fail to comply with certain
agreements. See "Description of Shares of Beneficial Interest - Preferred Shares
of Beneficial Interest - Series B Preferred Shares."

         Our Declaration of Trust generally provides that a trustee may be
removed from office only at a meeting of shareholders. However, a trustee
elected solely by holders of a series of Preferred Shares may be removed only by
the affirmative vote of a majority of the Preferred Shares of that series voting
as a single class.

Business Combinations

         Under Maryland law, as applicable to Maryland real estate investment
trusts, certain "business combinations" (including certain mergers,
consolidations, share exchanges, or, in certain circumstances, asset transfers
or issuances or reclassifications of equity securities) between a Maryland real
estate investment trust and an "interested shareholder" or an affiliate of the
interested shareholder are prohibited for five years after the most recent date
on which the interested shareholder becomes an interested shareholder. An
interested shareholder includes a person who beneficially owns, and an affiliate
or associate (as defined under Maryland law) of the trust who, at any time
during the two-year period prior to the date in question, was the beneficial
owner of 10% or more of the voting power of the trust's then outstanding voting
shares. Thereafter, any such business combination must be recommended by the
trustees of such trust and approved by the affirmative vote of at least:

                                      -9-



                  o     80% of the votes entitled to be cast by holders of
                        outstanding voting shares of beneficial interest of the
                        trust, voting together as a single voting group; and

                  o     two-thirds of the votes entitled to be cast by holders
                        of outstanding voting shares of beneficial interest
                        other than shares held by the interested shareholder
                        with whom or with whose affiliate the business
                        combination is to be effected or by the interested
                        shareholder's affiliates or associates, voting together
                        as a single voting group.

         These super-majority voting requirements do not apply if the trust's
common shareholders receive a minimum price (as defined under Maryland law) for
their shares and the consideration is received in cash or in the same form as
previously paid by the interested shareholder for its shares. These provisions
also do not apply to business combinations that are approved or exempted by the
Board of Trustees of the trust prior to the time that the interested shareholder
becomes an interested shareholder. An amendment to a Maryland REIT's declaration
of trust electing not to be subject to the foregoing requirements must be
approved by the affirmative vote of at least 80% of the votes entitled to be
cast by holders of outstanding voting shares of beneficial interest of the
trust, voting together as a single voting group, and two-thirds of the votes
entitled to be cast by holders of outstanding voting shares of beneficial
interest other than shares of beneficial interest held by interested
shareholders. Any such amendment shall not be effective until 18 months after
the vote of shareholders and does not apply to any business combination of the
trust with an interested shareholder that has such status on the date of the
shareholder vote. Our Board of Trustees has previously exempted any business
combinations involving Safeguard Scientifics, Inc., Pennsylvania State
Employees' Retirement System, LF Strategic Realty Investors L.P., Morgan Stanley
Asset Management Inc., Five Arrows Realty Securities III L.L.C. and Gerard H.
Sweeney and their respective affiliates and associates from the business
combination provisions summarized above and, consequently, the five-year
prohibition and the super-majority vote requirements will not apply to business
combinations between us and any of them.

         The business combination statute could have the effect of delaying,
deferring or preventing offers to acquire us and of increasing the difficulty of
consummating any such transaction.

Control Share Acquisitions

         Under Maryland law, as applicable to Maryland real estate investment
trusts, "control shares" of a Maryland real estate investment trust acquired in
a "control share acquisition" have no voting rights except to the extent
approved by a vote of two-thirds of the votes entitled to be cast on the matter
by shareholders, excluding shares owned by the acquiror, by officers or by
trustees who are employees of the trust in question. "Control shares" are voting
shares of beneficial interest which, if aggregated with all other shares
previously acquired by such acquiror or in respect of which the acquiror is able
to exercise or direct the exercise of voting power (except solely by virtue of a
revocable proxy), would entitle the acquiror to exercise the voting power in the
election of trustees within one of the following ranges of voting power:

         o        one-tenth or more but less than one-third,

         o        one-third or more but less than a majority, or

         o        a majority or more of all voting power.

         Control shares do not include shares the acquiring person is then
entitled to vote as a result of having previously obtained shareholder approval.
A "control share acquisition" means the acquisition of control shares, subject
to certain exceptions.

         A person who has made or proposes to make a control share acquisition,
upon satisfaction of certain conditions (including an undertaking to pay
expenses), may compel the trust's board of trustees to call a special meeting of
shareholders to be held within 50 days of demand to consider the voting rights
of the shares. If no request for a meeting is made, the trust may itself present
the question at any shareholders meeting.

                                      -10-



         If voting rights are not approved at the meeting or if the acquiring
person does not deliver an acquiring person statement as required by the
statute, then, subject to certain conditions and limitations, the trust may
redeem any or all of the control shares, except those for which voting rights
have previously been approved, for fair value determined, without regard to the
absence of voting rights for the control shares, as of the date of the last
control share acquisition by the acquiror or of any meeting of shareholders at
which the voting rights of such shares are considered and not approved. If
voting rights for control shares are approved at a shareholders meeting and the
acquiror becomes entitled to vote a majority of the shares entitled to vote, all
other shareholders may exercise appraisal rights. The fair value of the shares
as determined for purposes of such appraisal rights may not be less than the
highest price per share paid by the acquiror in the control share acquisition,
and certain limitations and restrictions otherwise applicable to the exercise of
dissenters' rights do not apply in the context of a control share acquisition.

         Our bylaws contain a provision exempting from the control share
acquisition statute any and all acquisitions by any person of our shares. There
can be no assurance that this provision will not be amended or eliminated at any
time in the future.

Amendment to the Declaration of Trust

         Our Declaration of Trust may be amended only by the affirmative vote of
the holders of not less than a majority of the Shares then outstanding and
entitled to vote thereon, except for the provisions of our Declaration of Trust
relating to (i) increases or decreases in the aggregate number of Shares of any
class (other than the Series A Preferred Shares and Series B Preferred Shares),
which may generally be made by our Board of Trustees without shareholder
approval and (ii) the Maryland General Corporation Law provisions on business
combinations, amendment of which requires the affirmative vote of the holders of
not less than 80% of the Shares then outstanding and entitled to vote. In
addition, if our Board of Trustees determines, with the advice of counsel, that
any one or more of the provisions of our Declaration of Trust conflict with the
Maryland REIT Law, the Internal Revenue Code or other applicable Federal or
state law(s), the conflicting provisions of our Declaration of Trust shall be
deemed never to have constituted a part of our Declaration of Trust, even
without any amendment thereof.

Termination of the Company and REIT Status

         Subject to the rights of any outstanding Preferred Shares and to the
provisions of the Maryland REIT Law, our Declaration of Trust permits our Board
of Trustees to terminate our existence and to discontinue our election to be
taxed as a REIT.

Transactions Between the Company and its Trustee or Officers

         Our Declaration of Trust provides that any contract or transaction
between us and one or more of our trustees, officers, employees or agents must
be approved by a majority of our trustees who have no interest in the contract
or transaction.

Limitation of Liability and Indemnification

         The Maryland REIT Law permits a Maryland real estate investment trust
to include in its Declaration of Trust a provision limiting the liability of its
trustees and officers to the trust and its shareholders for money damages.
However, a Maryland real estate investment trust may not eliminate liability
resulting from actual receipt of an improper benefit or profit in money,
property or services. Also, liability resulting from active and deliberate
dishonesty may not be eliminated if a final judgment establishes that the
dishonesty is material to the cause of action. Our Declaration of Trust contains
such a provision which eliminates such liability to the maximum extent permitted
by the Maryland REIT Law.

         Our Bylaws require us to indemnify, without requiring a preliminary
determination of the ultimate entitlement to indemnification, (a) any present or
former trustee, officer or shareholder who has been successful, on the merits or
otherwise, in the defense of a proceeding to which he was made a party by reason
of such status, against reasonable expenses incurred by him in connection with
the proceeding; (b) any present or former trustee or officer against any claim

                                      -11-



or liability to which he may become subject by reason of such status unless it
is established that (i) his act or omission was committed in bad faith or was
the result of active and deliberate dishonesty, (ii) he actually received an
improper personal benefit in money, property or services or (iii) in the case of
a criminal proceeding, he had reasonable cause to believe that his act or
omission was unlawful; and (c) each shareholder or former shareholder against
any claim or liability to which he may be subject by reason of such status as a
shareholder or former shareholder. However, under Maryland law, a Maryland
corporation may not indemnify for an adverse judgment in a suit by or in the
right of the corporation or for a judgment of liability on the basis that the
act or omission was material to the matter and was committed in bad faith, the
result of active and deliberate dishonesty or a personal benefit was improperly
received, or, if in a criminal proceeding, there was reasonable cause to believe
the act or omission was unlawful. In addition, our Bylaws require us to pay or
reimburse, in advance of final disposition of a proceeding, reasonable expenses
incurred by a present or former trustee, officer or shareholder made a party to
a proceeding by reason of his status as a trustee, officer or shareholder
provided that, in the case of a trustee or officer, we shall have received (i) a
written affirmation by the trustee or officer of his good faith belief that he
has met the applicable standard of conduct necessary for our indemnification as
authorized by the Bylaws and (ii) a written undertaking by him or on his behalf
to repay the amount paid or reimbursed by us if it shall ultimately be
determined that the applicable standard of conduct was not met. Our Bylaws also
(i) permit us, with the approval of our trustees, to provide indemnification and
payment or reimbursement of expenses to a present or former trustee, officer or
shareholder who served our predecessor in such capacity, and to any of our
employees or agents or our predecessors, (ii) provide that any indemnification
or payment or reimbursement of the expenses permitted by our Bylaws shall be
furnished in accordance with the procedures provided for indemnification and
payment or reimbursement of expenses under Section 2-418 of the Maryland General
Corporation Law for directors of Maryland corporations and (iii) permit us to
provide such other and further indemnification or payment or reimbursement of
expenses as may be permitted by the Maryland General Corporation Law for
directors of Maryland corporations.

         The limited partnership agreement of the Operating Partnership also
provides for indemnification by the Operating Partnership of us, as general
partner, and our trustees and officers for any costs, expenses or liabilities
incurred by us or them by reason of any act performed by us or them for or on
behalf of the Operating Partnership or us; provided that such person's actions
were taken in good faith and in the belief that such conduct was in the best
interests of the Operating Partnership and that such person was not guilty of
fraud, willful misconduct or gross negligence.

         Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to our trustees and officers pursuant to the foregoing
provisions or otherwise, we have been advised that, although the validity and
scope of the governing statute has not been tested in court, in the opinion of
the Securities and Exchange Commission, such indemnification is against public
policy as expressed in the Securities Act and is, therefore, unenforceable. In
addition, indemnification may be limited by state securities laws.

                 INDEMNIFICATION FOR SECURITIES ACT LIABILITIES

         Our Declaration of Trust and Bylaws contain provisions to indemnify our
trustees and officers against liability incurred by them as a result of their
services as trustees and officers. We have been informed that in the opinion of
the Securities and Exchange Commission, our indemnification of our trustees,
officers or controlling persons for liabilities arising under the Securities Act
of 1933, as amended, is against public policy as expressed in the Securities
Act, and therefore is unenforceable.

                               SELLING SHAREHOLDER

Common Shares

         Pursuant to the terms of a Registration Rights Agreement (a copy of
which is attached as Exhibit 10.4 to our Quarterly Report on Form 10-Q filed
with the SEC on August 13, 1998) we are registering 3,679,245 Common Shares for
resale by the Selling Shareholder if and to the extent the Selling Shareholder
elects to convert all or a portion of its Series B Preferred Units into Class A
Units and such Class A Units are subsequently redeemed for Common Shares.
Following an issuance of Common Shares upon redemption of Class A Units, the
Selling Shareholder may resell the Common Shares as provided under the section
of this Prospectus entitled "Plan of Distribution" and in any applicable
Prospectus supplement.

                                      -12-



         The following table provides the name of, and the number of Common
Shares beneficially owned by, the Selling Shareholder as of October 1, 2003.
Since the Selling Shareholder may sell all, some or none of its Common Shares,
no estimate can be made of the aggregate number of Common Shares that are to be
offered and sold hereunder or that will be owned by the Selling Shareholder upon
completion of the offering to which this Prospectus relates.

                              PLAN OF DISTRIBUTION

         This Prospectus relates to the offer and sale from time to time of up
to 3,679,245 Common Shares that may be issued to the Selling Shareholder upon
conversion of Series B Preferred Units into Class A Units, and upon redemption
of the Class A Units for Common Shares. We are registering the offer and sale of
the Common Shares by the Selling Shareholder, but the registration of these
Common Shares does not necessarily mean that any or all of such Common Shares
will be offered or sold by the Selling Shareholder.

         We will not receive any proceeds from the sale of the Common Shares by
the Selling Shareholder. "Selling Shareholder" includes affiliates, donees,
transferees, distributees, and pledgees selling Common Shares received from the
named Selling Shareholder after the date of this Prospectus.

         The securities covered by this Prospectus may be offered and sold at
various times by the Selling Shareholder. The Selling Shareholder will act
independently of us in making decisions with respect to the securities covered
by this Prospectus and may offer these securities in one or more of the
following transactions:

         o        on any national securities exchange or quotation service on
                  which the securities may be listed or quoted at the time of
                  sale;

         o        in the over-the-counter market;

         o        in transactions other than on such exchange or in the
                  over-the-counter market;

         o        in brokerage transactions;

                                      -13-

         o        through put or call options;

         o        in privately negotiated transactions;

         o        in connection with short sales;

         o        through underwriters, brokers or dealers (who may act as agent
                  or principal);

         o        by pledge to secure debts and other obligations;

         o        in open market sales in reliance upon Rule 144 under the
                  Securities Act of 1933;

         o        in connection with the writing of non-traded and
                  exchange-traded call options, in hedge transactions and in
                  settlement of other transactions in standardized or
                  over-the-counter options; or

         o        in a combination of any of the above transactions.

         The Selling Shareholder may sell securities covered by this Prospectus
at market prices prevailing at the time of sale, at prices related to such
prevailing market prices, at negotiated prices or at fixed prices. The Selling
Shareholder reserves the sole right to accept and, together with any agent of
the Selling Shareholder, to reject in whole or in part any proposed purchase of
its securities covered by this Prospectus.

         Securities covered by this Prospectus may be sold from time to time to
purchasers directly by the Selling Shareholder or to or through underwriters,
dealers or agents, who may receive compensation in the form of discounts,
concessions or commissions from the Selling Shareholder and/or the purchasers of
securities for whom they may act as an agent (which compensation as to a
particular broker-dealer might be in excess of customary commissions). These
broker-dealers may act either as agent of the Selling Shareholder or as a
principal for the broker-dealer's own account. These transactions may include
transactions in which the same broker-dealer acts as an agent on both sides of
the trade. The Selling Shareholder and any dealers or agents that participate in
the distribution of securities covered by this Prospectus may be deemed to be
"underwriters" within the meaning of Section 2(11) of the Securities Act of
1933, and any profit on the sale of securities covered by this Prospectus and
any commissions received by any dealers or agents might be deemed to be
underwriting commissions under the Securities Act of 1933.

         Because the Selling Shareholder may be deemed to be an "underwriter"
within the meaning of Section 2(11) of the Securities Act of 1933, the Selling
Shareholder will be subject to the prospectus delivery requirements of the
Securities Act of 1933. We have informed the Selling Shareholder that the
anti-manipulation provisions of Regulation M promulgated under the Securities
Exchange Act of 1934 may apply to its sales in the market. However, the
registration of the securities registered by this Prospectus shall not be deemed
an admission by the Selling Shareholder that it is or that anyone acting on its
behalf is an "underwriter."

         At a time any particular offer of securities covered by this Prospectus
is made by the Selling Shareholder, a supplement to this Prospectus, if
required, will be distributed setting forth its name and the names of any
dealers or agents and any commissions and other terms constituting compensation
from the Selling Shareholder and any other required information.

         Under an agreement with the Selling Shareholder, we will pay
substantially all of the expenses incident to the registration of the resale of
the securities covered by this Prospectus. Under an agreement entered into with
the Selling Shareholder, the Selling Shareholder and any underwriter the Selling
Shareholder may utilize will be indemnified by us against certain civil
liabilities, including liabilities under the Securities Act of 1933.
