                            MEETINGS OF SHAREHOLDERS

     Section 1. Place. All meetings of shareholders shall be held at the
principal executive office of the Trust or at such other place as shall be
stated in the notice of the meeting.

     Section 2. Annual Meeting. An annual meeting of the shareholders for the
election of Trustees and the transaction of any business within the powers of
the Trust shall be held annually and at the time set by the Trustees.

     Section 3. Special Meetings.

         (a) General. The President, Chairman of the Board or Board of Trustees
may call a special meeting of the shareholders. Subject to subsection (b) of
this Section 3, a special meeting of shareholders shall also be called by the
Secretary of the Trust upon the written request of the shareholders in
accordance with Article 7 of the Declaration of Trust of the Trust.

         (b) (1) Any shareholder of record seeking to have shareholders request
a special meeting shall, by sending written notice to the secretary (the "Record
Date Request Notice") by registered mail, return receipt requested, request the
Board of Trustees to fix a record date to determine the shareholders entitled to
request a special meeting (the "Request Record Date"). The Record Date Request
Notice shall set forth the purpose of the meeting and the matters proposed to be
acted on at it, shall be signed by one or more shareholders of record as of the
date of signature (or their duly authorized proxies or other agents), shall bear
the date of signature of each such shareholder (or proxy or other agent) and
shall set forth all information relating to each such shareholder that must be
disclosed in solicitations of proxies for election of trustees in an election
contest (even if an election contest is not involved), or is otherwise required,
in each case pursuant to Regulation 14A under the Securities Exchange Act of
1934, as amended (the "Exchange Act"), and Rule 14a-11 thereunder. Upon
receiving the Record Date Request Notice, the Board of Trustees may fix a
Request Record Date. The Request Record Date shall not precede and shall not be
more than ten days after the close of business on the date on which the
resolution fixing the Request Record Date is adopted by the Board of Trustees.




If the Board of Trustees, within ten days after the date on which a valid Record
Date Request Notice is received, fails to adopt a resolution fixing the Request
Record Date and make a public announcement of such Request Record Date, the
Request Record Date shall be the close of business on the tenth day after the
first date on which the Record Date Request Notice is received by the secretary.

         (2) In order for any shareholder to request a special meeting, one or
more written requests for a special meeting signed by shareholders of record (or
their duly authorized proxies or other agents) as of the Request Record Date
entitled to vote not less than ten percent (the "Special Meeting Percentage") of
the issued and outstanding Common Shares of Beneficial Interest (as defined in
the Declaration of Trust) (the "Special Meeting Request") shall be delivered to
the secretary. In addition, the Special Meeting Request shall set forth the
purpose of the meeting and the matters proposed to be acted on at it (which
shall be limited to the matters set forth in the Record Date Request Notice
received by the secretary), shall bear the date of signature of each such
shareholder (or proxy or other agent) signing the Special Meeting Request, shall
set forth the name and address, as they appear in the Trust's books, of each
shareholder signing such request (or on whose behalf the Special Meeting Request
is signed) and the class and number of shares of beneficial interest of the
Trust which are owned of record and beneficially by each such shareholder, shall
be sent to the secretary by registered mail, return receipt requested, and shall
be received by the secretary within 60 days after the Request Record Date. Any
requesting shareholder may revoke his, her or its request for a special meeting
at any time by written revocation delivered to the secretary.

         (3) The secretary shall inform the requesting shareholders of the
reasonably estimated cost of preparing and mailing the notice of meeting
(including the Trust's proxy materials). The secretary shall not be required to
call a special meeting upon shareholder request and such meeting shall not be
held unless, in addition to the documents required by paragraph (2) of this
Section 3(b), the secretary receives payment of such reasonably estimated cost
prior to the mailing of any notice of the meeting.

         (4) Except as provided in the next sentence, any special meeting shall
be held at such place, date and time as may be designated by the chairman or
Board of Trustees, whoever has called the meeting. In the case of any special
meeting called by the secretary upon the request of shareholders (a "Shareholder
Requested Meeting"), such meeting shall be held at such place, date and time as
may be designated by the Board of Trustees; provided, however, that the date of
any Shareholder Requested Meeting shall be not more than 90 days after the
record date for such meeting (the "Meeting Record Date"); and provided further
that if the Board of Trustees fails to designate, within ten days after the date
that a valid Special Meeting Request is actually received by the secretary (the
"Delivery Date"), a date and time for a Shareholder Requested Meeting, then such
meeting shall be held at 2:00 p.m. local time on the 90th day after the Meeting
Record Date or, if such 90th day is not a Business Day (as defined below) , on
the first preceding Business Day; and provided further that in the event that
the Board of Trustees fails to designate a place for a Shareholder Requested
Meeting within ten days after the Delivery Date, then such meeting shall be held
at the principal executive offices of the Trust. In fixing a date for any
special meeting, the chairman or Board of Trustees may consider such factors as
he, she or it deems relevant within the good faith exercise of business
judgment, including, without limitation, the nature of the matters to be


                                      -2-




considered, the facts and circumstances surrounding any request for meeting and
any plan of the Board of Trustees to call an annual meeting or a special
meeting. In the case of any Shareholder Requested Meeting, if the Board of
Trustees fails to fix a Meeting Record Date that is a date within 30 days after
the Delivery Date, then the close of business on the 30th day after the Delivery
Date shall be the Meeting Record Date.

         (5) If at any time as a result of written revocations of requests for
the special meeting, shareholders of record (or their duly authorized proxies or
other agents) as of the Request Record Date entitled to cast less than the
Special Meeting Percentage shall have delivered and not revoked requests for a
special meeting, the secretary may refrain from mailing the notice of the
meeting or, if the notice of the meeting has been mailed, the secretary may
revoke the notice of the meeting at any time before ten days before the meeting
if the secretary has first sent to all other requesting shareholders written
notice of such revocation and of intention to revoke the notice of the meeting.
Any request for a special meeting received after a revocation by the secretary
of a notice of a meeting shall be considered a request for a new special
meeting.

         (6) The chairman, President or the Board of Trustees may appoint
regionally or nationally recognized independent inspectors of elections to act
as the agent of the Trust for the purpose of promptly performing a ministerial
review of the validity of any purported Special Meeting Request received by the
secretary. For the purpose of permitting the inspectors to perform such review,
no such purported Special Meeting Request shall be deemed to have been delivered
to the secretary until the earlier of (i) five Business Days after receipt by
the secretary of such purported request and (ii) such date as the independent
inspectors certify to the Trust that the valid requests received by the
secretary represent at least ten percent of the issued and outstanding Common
Shares of Beneficial Interest. Nothing contained in this paragraph (6) shall in
any way be construed to suggest or imply that the Trust or any shareholder shall
not be entitled to contest the validity of any request, whether during or after
such five Business Day period, or to take any other action (including, without
limitation, the commencement, prosecution or defense of any litigation with
respect thereto, and the seeking of injunctive relief in such litigation).

         (7) For purposes of these Bylaws, "Business Day" shall mean any day
other than a Saturday, a Sunday or a day on which banking institutions in the
State of New York or the Commonwealth of Pennsylvania are authorized or
obligated by law or executive order to close.

         (8) Notwithstanding the foregoing provisions of this Section 3, holders
of a class or series of preferred shares of beneficial interest of the Trust may
call a special meeting in accordance with applicable provisions of the
Declaration of Trust or as otherwise permitted by law.

     Section 4. Notice. Not less than ten nor more than 90 days before each
meeting of shareholders, the secretary shall give to each shareholder entitled
to vote at such meeting and to each shareholder not entitled to vote who is
entitled to notice of the meeting written or printed notice stating the time and
place of the meeting and, in the case of a special meeting or as otherwise may
be required by statute, the purpose for which the meeting is called, either by


                                      -3-





mail, by presenting it to such shareholder personally, by leaving it at his
residence or usual place of business or by any other means permitted by Maryland
law. If mailed, such notice shall be deemed to be given when deposited in the
United States mail addressed to the shareholder at his post office address as it
appears on the records of the Trust, with postage thereon prepaid.

     Section 5. Scope of Notice. Any business of the Trust may be transacted
at an annual meeting of shareholders without being specifically designated in
the notice, except such business as is required by statute to be stated in such
notice. No business shall be transacted at a special meeting of shareholders
except as specifically designated in the notice.

     Section 6. Organization and Conduct of Meetings. Every meeting of
shareholders shall be conducted by an individual appointed by the Board of
Trustees to be chairman of the meeting or, in the absence of such appointment,
by the chairman of the board or, in the case of a vacancy in the office or
absence of the chairman of the board, by one of the following officers present
at the meeting: the president, the vice presidents in their order of rank and
seniority or, in the absence of such officers, a chairman chosen by the
shareholders by the vote of a majority of the votes cast by shareholders present
in person or by proxy. The secretary or, in the secretary's absence, an
assistant secretary, or in the absence of both the secretary and assistant
secretaries, a person appointed by the Board of Trustees or, in the absence of
such appointment, a person appointed by the chairman of the meeting shall act as
secretary. In the event that the secretary presides at a meeting of the
shareholders, an assistant secretary shall record the minutes of the meeting.
The order of business and all other matters of procedure at any meeting of
shareholders shall be determined by the chairman of the meeting. The chairman of
the meeting may prescribe such rules, regulations, and procedures and take such
action as, in the discretion of such chairman, are appropriate for the proper
conduct of the meeting, including, without limitation, (a) restricting admission
to the time set for the commencement of the meeting; (b) limiting attendance at
the meeting to shareholders of record of the Trust, their duly authorized
proxies or other such persons as the chairman of the meeting may determine; (c)
limiting participation at the meeting on any matter to shareholders of record of
the Trust entitled to vote on such matter, their duly authorized proxies or
other such persons as the chairman of the meeting may determine; (d) limiting
the time allotted to questions or comments by participants; (e) maintaining
order and security at the meeting; (f) removing any shareholder who refuses to
comply with meeting procedures, rules or guidelines as set forth by the
chairman; and (g) recessing or adjourning the meeting to a later date and time
and place announced at the meeting. Unless otherwise determined by the chairman
of the meeting, meetings of shareholders shall not be required to be held in
accordance with the rules of parliamentary procedure.

     Section 7. Quorum. At any meeting of shareholders, the presence in
person or by proxy of shareholders entitled to cast a majority of all the votes
entitled to be cast at such meeting shall constitute a quorum; but this section
shall not affect any requirement under any statute or the Declaration of Trust
for the vote necessary for the adoption of any measure. If, however, such quorum
shall not be present at any meeting of the shareholders, the chairman of the
meeting or the shareholders entitled to vote at such meeting, present in person
or by proxy, shall have power to adjourn the meeting from time to time to a date
not more than 120 days after the original record date without notice other than
announcement at the meeting. At such adjourned meeting at which a quorum shall
be present, any business may be transacted which might have been transacted at
the meeting as originally notified.

                                      -4-





     Section 8. Voting. A plurality of all the votes cast at a meeting of
shareholders duly called and at which a quorum is present shall be sufficient to
elect a Trustee. Shareholders shall not be entitled to cumulate their votes in
the election of Trustees. A majority of the votes cast at a meeting of
shareholders duly called and at which a quorum is present shall be sufficient to
approve any other matter which may properly come before the meeting, unless more
than a majority of the votes cast is required by statute or by the Declaration
of Trust. Unless otherwise provided in the Declaration, each outstanding share,
regardless of class, shall be entitled to one vote on each matter submitted to a
vote at a meeting of shareholders.

     Section 9. Proxies. A shareholder may cast the votes entitled to be
cast by the shares of beneficial interest owned of record by the shareholder,
either in person or by proxy executed in any manner permitted by law by the
shareholder or by his duly authorized agent. Such proxy shall be filed with the
secretary of the Trust before or at the meeting. No proxy shall be valid more
than eleven months after its date, unless otherwise provided in the proxy.

     Section 10. Voting of Shares by Certain Holders. Shares registered in
the name of a corporation, partnership, trust or other entity, if entitled to be
voted, may be voted by the chief executive officer or a vice president, a
general partner or trustee thereof, as the case may be, or a proxy appointed by
any of the foregoing individuals, unless some other person who has been
appointed to vote such shares pursuant to a bylaw or a resolution of the board
of directors of such corporation or other entity presents a certified copy of
such bylaw or resolution, in which case such person may vote such shares. Any
trustee or other fiduciary may vote shares registered in his name as such
fiduciary, either in person or by proxy.

     Shares of the Trust directly or indirectly owned by it shall not be
voted at any meeting and shall not be counted in determining the total number of
outstanding shares entitled to be voted at any given time, unless they are held
by it in a fiduciary capacity, in which case they may be voted and shall be
counted in determining the total number of outstanding shares at any given time.

     The Trustees may adopt by resolution a procedure by which a shareholder
may certify in writing to the Trust that any shares registered in the name of
the shareholder are held for the account of a specified person other than the
shareholder. The resolution shall set forth the class of shareholders who may
make the certification, the purpose for which the certification may be made, the
form of certification and the information to be contained in it; if the
certification is with respect to a record date or closing of the share transfer
books, the time after the record date or closing of the share transfer books
within which the certification must be received by the Trust; and any other
provisions with respect to the procedure which the Trustees consider necessary
or desirable. On receipt of such certification, the person specified in the
certification shall be regarded as, for the purposes set forth in the
certification, the shareholder of record of the specified shares in place of the
shareholder who makes the certification.

     Section 11. Inspectors. At any meeting of shareholders, the chairman of
the meeting may, or upon the request of any shareholder shall, appoint one or
more persons as inspectors for such meetings. Such inspectors shall ascertain
and report the number of shares represented at the meeting based upon their
determination of the validity and effect of proxies, count all votes, report the
results and perform such other acts as are proper to conduct the election and
voting with impartiality and fairness to all the shareholders.

                                      -5-





     Each report of an inspector shall be in writing and signed by him or by
a majority of them if there is more than one inspector acting at such meeting.
If there is more than one inspector, the report of a majority shall be the
report of the inspectors. The report of the inspector or inspectors on the
number of shares represented at the meeting and the results of the voting shall
be prima facie evidence thereof.

     Section 12. Voting by Ballot. Voting on any question or in any election
may be viva voce unless the presiding officer shall order or any shareholder
shall demand that voting be by ballot.

     Section 13. No Shareholder Action by Written Consent. Subject to the
rights of the holders of any series Preferred Shares to elect additional
Trustees under specific circumstances, any action required or permitted to be
taken by the shareholders of the Trust must be effected at an annual or special
meeting of shareholders and may not be effected by any consent in writing by
such shareholders.

     Section 14. Nominations and Proposals by Shareholders.

         (a) Annual Meetings of Shareholders. (1) Nominations of persons for
election to the Board of Trustees and the proposal of business to be considered
by the shareholders may be made at an annual meeting of shareholders (i)

Board of Trustees or (iii) by any shareholder of the Trust who was a shareholder
of record both at the time of giving of notice provided for in this Section
14(a) and at the time of the annual meeting, who is entitled to vote at the
meeting and who complied with the notice procedures set forth in this Section
14(a).

         (2) For nominations for election to the Board of Trustees or other
business to be properly brought before an annual meeting by a shareholder
pursuant to clause (iii) of paragraph (a)(1) of this Section 14, the shareholder
must have given timely notice thereof in writing to the secretary of the Trust
and such other business must otherwise be a proper matter for action by
shareholders. To be timely, a shareholder's notice must be delivered to the
secretary at the principal executive office of the Trust by not later than the
close of business on the 90th day prior to the first anniversary of the date of
mailing of the notice for the preceding year's annual meeting nor earlier than
the close of business on the 120th day prior to the first anniversary of the
date of mailing of the notice for the preceding year's annual meeting; provided,
however, that in the event that the date of the mailing of the notice for the
annual meeting is advanced or delayed by more than 30 days from the anniversary
date of the mailing of the notice for the preceding year's annual meeting,
notice by the shareholder to be timely must be so delivered not earlier than the
close of business on the 120th day prior to the date of mailing of the notice
for such annual meeting and not later than the close of business on the later of
the 90th day prior to the date of mailing of the notice for such annual meeting
or the tenth day following the day on which public announcement of the date of
mailing of the notice for such meeting is first made by the Trust. In no event
shall the public announcement of a postponement of the mailing of the notice for
such annual meeting or of an adjournment or postponement of an annual meeting to

                                      -6-





a later date or time commence a new time period for the giving of a
shareholder's notice as described above. A shareholder's notice to be proper
must set forth (i) as to each person whom the shareholder proposes to nominate
for election or reelection as a Trustee (A) the name, age, business address and
residence address of such person, (a) the class and number of shares of
beneficial interest of the Trust that are beneficially owned or owned of record
by such person and (C) all other information relating to such person that is
required to be disclosed in solicitations of proxies for election of directors
in an election contest or is otherwise required, in each case pursuant to
Regulation 14A (or any successor provision) under the Exchange Act (including
such person's written consent to being named in the proxy statement as a nominee
and to serving as a Trustee if elected); (ii) as to any other business that the
shareholder proposes to bring before the meeting, a description of the business
desired to be brought before the meeting, the reasons for conducting such
business at the meeting and any material interest in such business of such
shareholder (including any anticipated benefit to the shareholder therefrom) and
of each beneficial owner, if any, on whose behalf the proposal is made; and
(iii) as to the shareholder giving the notice and each beneficial owner, if any,
on whose behalf the nomination or proposal is made, (x) the name and address of
such shareholder, as they appear on the Trust's share ledger and current name
and address, if different, and of such beneficial owner and (y) the class and
number of shares of beneficial interest of the Trust which are owned
beneficially and of record by such shareholder and such beneficial owner.

         (3) Notwithstanding anything in the second sentence of paragraph (a)(2)
of this Section 14 to the contrary, in the event that the number of Trustees to
be elected to the Board of Trustees is increased and there is no public
announcement by the Trust of such action or specifying the size of the increased
Board of Trustees at least 100 days prior to the first anniversary of the date
of mailing of the notice for the preceding year's annual meeting, a
shareholder's notice required by this Section 14(a) shall also be considered
timely, but only with respect to nominees for any new positions created by such
increase, if the notice is delivered to the secretary at the principal executive
offices of the Trust not later than the close of business on the tenth day
immediately following the day on which such public announcement is first made by
the Trust.

     (b) Special Meetings of Shareholders. Only such business shall be
conducted at a special meeting of shareholders as shall have been brought before
the meeting pursuant to the Trust's notice of meeting.

     (c) General. (1) Only such persons who are nominated in accordance with
the procedures set forth in this Section 14 shall be eligible to serve as
Trustees, and only such business shall be conducted at a meeting of shareholders
as shall have been brought before the meeting in accordance with the procedures
set forth in this Section 14. The chairman of the meeting shall have the power
and duty to determine whether a nomination or any other business proposed to be
brought before the meeting was made or proposed, as the case may be, in
accordance with the procedures set forth in this Section 14 and, if any proposed
nomination or other business is not in compliance with this Section 14, to
declare that such nomination or proposal shall be disregarded.

         (2) For purposes of this Section 14, (a) the "date of mailing of the

shareholder shall also comply with all applicable requirements of state law and
of the Exchange Act and the rules and regulations thereunder with respect to the
matters set forth in this Section 14. Nothing in this Section 14 shall be deemed
to affect any right of a shareholder to request inclusion of a proposal in, nor
the right of the Trust to omit a proposal from, the Trust's proxy statement
pursuant to Rule 14a-8 (or any successor provision) under the Exchange Act.

convened may continue to transact business until adjournment, notwithstanding
the withdrawal of enough Trustees to leave less than a quorum.

     Section 6. Voting. The action of the majority of the Trustees present
at a meeting at which a quorum is present shall be the action of the Trustees,

such written consent is filed with the minutes of proceedings of the Trustees.

     Section 9. Vacancies and Resignations. If for any reason any or all the
Trustees cease to be Trustees, such event shall not terminate the Trust or
affect these Bylaws or the powers of the remaining Trustees hereunder (even if
fewer than three Trustees remain). Any vacancy (including a vacancy created by
an increase in the number of Trustees) shall be filled, at any regular meeting
or at any special meeting called for that purpose, by a majority of the
remaining Trustees, even if such majority is less than a quorum. Any individual
so elected as Trustee shall serve for the unexpired term of the trustee he is
replacing until his successor has been duly elected and qualified. Any Trustee
of the Trust may resign at any time by giving written notice of his resignation
to the Board of Trustees, the chairman of the board, the president or the
secretary. Any resignation shall take effect immediately upon its receipt or at
such later time as specified therein. The acceptance of a resignation shall not
be necessary to make it effective unless otherwise stated in the resignation.

     Section 10. Compensation. Trustees shall not receive any stated salary
for their services as Trustees but, by resolution of the trustees, fixed sums
per year and/or per meeting. Expenses of attendance, if any, may be allowed to
trustees for attendance at each annual, regular or special meeting of the
Trustees or of any committee thereof; but nothing herein contained shall be
construed to preclude any Trustees from serving the Trust in any other capacity
and receiving compensation therefor.

     Section 11. Removal of Trustees. The shareholders may, at any time,
remove any Trustee in the manner provided in the Declaration of Trust.

     Section 12. Loss of Deposits. No Trustee shall be liable for any loss
which may occur by reason of the failure of the bank, trust company, savings and
loan association, or other institution with whom moneys or shares have been
deposited.

     Section 13. Surety Bonds. Unless required by law, no Trustee shall be
obligated to give any bond or surety or other security for the performance of
any of his duties.

     Section 14. Reliance. Each Trustee, officer, employee and agent of the
Trust shall, in the performance of his duties with respect to the Trust, be
fully justified and protected with regard to any act or failure to act in
reliance in good faith upon the books of account or other records of the Trust,
upon an opinion of counsel or upon reports made to the Trust by any of its
officers or employees or by the adviser, accountants, appraisers or other
experts or consultants selected by the Trustees or officers of the Trust,
regardless of whether such counsel or expert may also be a Trustee.

     Section 15. Certain Rights of Trustees, Officers, Employees and Agents.
The Trustees shall have no responsibility to devote their full time to the
affairs of the Trust. Any Trustee or officer, employee or agent of the Trust, in
his personal capacity or in a capacity as an affiliate, employee, or agent of
any other person, or otherwise, may have business interests and engage in
business activities similar to or in addition to those of or relating to the
Trust.

                                   COMMITTEES

     Section 1. Number, Tenure and Qualifications. The Trustees may, by
resolution or resolutions passed by a majority of the whole Board, appoint from
among its members an Executive Committee, an Audit Committee and other
committees, composed of one or more Trustees.

     Section 2. Powers. The Trustees may delegate to committees appointed
under Section 1 of this Article any of the powers of the Board of Trustees.

     Section 3. Committee Procedures. Each Committee may fix rules of
procedure for its business. A majority of the members of a committee shall
constitute a quorum for the transaction of business and the action of a majority
of those present at a meeting at which a quorum is present shall be action of
the committee. In the absence of any member of any committee, the members
thereof present at any meeting, whether or not they constitute a quorum, may
appoint another Trustee to act in the place of such absent member. Any action
required or permitted to be taken at a meeting of a committee may be taken
without a meeting, if a unanimous written consent which sets forth the action is
signed by each member of the committee and filed with the minutes of the
proceedings of such committee. The members of a committee may conduct any
meeting thereof by means of a conference telephone or similar communications
equipment if all persons participating in the meeting can hear each other at the
same time. Participation in a meeting by such means shall constitute presence in
person at the meeting.

     Section 4. Emergency. In the event of a state of disaster of sufficient
severity to prevent the conduct and management of the affairs and business of
the Trust by its Trustees and officers as contemplated by the Declaration of
Trust and these Bylaws, any two or more available members of the then incumbent
Executive Committee, if any, shall constitute a quorum of that Committee for the
full conduct and management of the affairs and business of the Trust in
accordance with the provisions of this Article. In the event of the
unavailability, at such time, of a minimum of two members of the then incumbent
Executive Committee, the available Trustees shall elect an Executive Committee
composed of any two members of the Board of Trustees, whether or not they be
officers of the Trust, which two members shall constitute the Executive
Committee for the full conduct and management of the affairs of the Trust in
accordance with the foregoing provisions of this Section. This Section shall be
subject to implementation by resolution of the Board of Trustees passed form
time to time for that purpose, and any provisions of the Bylaws (other than this
Section) and any resolutions which are contrary to the provisions of this
Section or to the provisions of any such implementing resolutions shall be
suspended until it shall be determined by any interim Executive Committee acting
under this Section that it shall be to the advantage of the Trust to resume the
conduct and management of its affairs and business under all the other
provisions of these Bylaws.

office until his successor is elected and qualifies or until his death,
resignation or removal in the manner hereinafter provided. Any two or more

leave unfilled any office. Election of an officer or agent shall not of itself
create contract rights between the Trust and such officer or agent.

     Section 2. Removal and Resignation. Any officer of the Trust may be
removed by a majority of the members of the Whole Board if in their judgment the
best interests of the Trust would be served thereby, but such removal shall be
without prejudice to the contract rights, if any, of the person so removed. Any
officer of the Trust may resign at any time by giving written notice of his
resignation to the Trustees, the chairman of the board, the chief executive
officer or the secretary. Any resignation shall take effect immediately after
its receipt or at such late time specified therein. The acceptance of a

of the Trust. He may execute any deed, mortgage, bond, contract or other

the Trust or shall be required by law to be otherwise executed; and in general
shall perform all duties incident to the office of chief executive officer and

officer or in the event of a vacancy in such office, the vice president (or in
the event there be more than one vice president, the vice presidents in the
order designated at the time of their election or, in the absence of any
designation, then in the order of their election ) shall perform the duties of
the chief executive officer and when so acting shall have all the powers of and
be subject to all the restrictions upon the chief executive officer; and shall

have the custody of the funds and securities of the Trust and shall keep full
and accurate accounts of receipts and disbursements in books belonging to the
Trust and shall deposit all moneys and other valuable effects in the name and to
the credit of the Trust in such depositories as may be designated by the
Trustees.

     The chief financial officer shall disburse the funds of the Trust as
may be ordered by the Trustees, taking proper vouchers for such disbursements,
and shall render to the chief executive officer and Trustees, at the regular
meetings of the Trustees or whenever they may require it, an account of all his

Trust.

     If required by the Trustees, he shall give the Trust a bond in such sum

                                      -13-





                                  ARTICLE VI.

                      CONTRACTS, LOANS, CHECKS AND DEPOSITS

     Section 1. Contracts. The Trustees may authorize any officer or agent
to enter into any contract or to execute and deliver any instrument in the name
of and on behalf of the Trust and such authority may be general or confined to
specific instances. Any agreement, deed, mortgage, lease or other document shall
be valid and binding upon the Trustees and upon the Trust when so authorized or
ratified by action of the Board of Trustees and executed by an authorized
person.

     Section 2. Checks and Drafts. All checks, drafts or other orders for
the payment of money, notes or other evidences of indebtedness issued in the
name of the Trust shall be signed by such officer or officers, agent or agents
of the Trust and in such manner as shall from time to time be determined by the
Trustees.

                                  ARTICLE VII.

                                     SHARES

     Section 1. Certificates. Except as otherwise provided in these Bylaws,
this Section shall not be interpreted to limit the authority of the Board of
Trustees to issue some or all of the shares of any or all classes or series
without certificates. Each shareholder, upon written request to the Secretary of
Trust, shall be entitled to a certificate or certificates which shall represent
and certify the number of shares of each class of beneficial interests held by
him in the Trust. Each certificate shall be signed by the chief executive
officer or a vice president and countersigned by the secretary or an assistant
secretary or the chief financial officer or an assistant treasurer and may be
sealed with the seal, if any, of the Trust. The signatures may be either manual
or facsimile. Certificates shall be consecutively numbered; and if the Trust
shall, from time to time, issue several classes of shares, each class may have
its own number series. A certificate is valid and may be issued whether or not
an officer who signed it is still an officer when it is issued. Each certificate
representing shares which are restricted as to their transferability or voting
powers, which are preferred or limited as to their dividends or as to their
allocable portion of the assets upon liquidation or which are redeemable at the
option of the Trust, shall have a statement of such restriction, limitation,
preference or redemption provision, or a summary thereof, plainly stated on the
certificate. In lieu of such statement or summary, the Trust may set forth upon
the face or back of the certificate a statement that the Trust will furnish to
any shareholder, upon request and without charge, a full statement of such
information.

     Section 2. Transfers. Certificates shall be treated as negotiable and
title thereto and to the shares they represent shall be transferred by delivery
thereof to the same extent as those of a Maryland stock corporation. Upon
surrender to the Trust or the transfer agent of the Trust of a share certificate
duly endorsed or accompanied by proper evidence of succession, assignment or
authority to transfer, the Trust shall issue a new certificate to the person
entitled thereto, cancel the old certificate and record the transaction upon its
books.


                                      -14-





     The Trust shall be entitled to treat the holder of record of any share
or shares as the holder in fact thereof and, accordingly, shall not be bound to
recognize any equitable or other claim to or interest in such share on the part
of any other person, whether or not it shall have express or other notice
thereof, except as otherwise provided by the laws of the State of Maryland.

     Section 3. Lost Certificate. The Trustees may direct a new certificate
to be issued in place of any certificate previously issued by the Trust alleged
to have been lost, stolen or destroyed upon the making of an affidavit of that
fact by the person claiming the certificate to be lost, stolen or destroyed.
When authorizing the issuance of a new certificate, the Trustees may, in their
discretion and as a condition precedent to the issuance thereof, require the
owner of such lost, stolen or destroyed certificate or his legal representative
to advertise the same in such manner as they shall require and/or to give bond,
with sufficient surety, to the Trust to indemnify it against any loss or claim
which may arise as a result of the issuance of a new certificate.

     Section 4. Closing of Transfer Books or Fixing of Record Date. The Trustees
may set, in advance a record date for the purpose of determining shareholders
entitled to notice of or to vote at any meeting of shareholders, or shareholders
entitled to receive payment of any dividend or the allotment of any other
rights, or in order to make a determination of shareholders for any other proper
purpose. Such date, in any case, shall not be prior to the close of business on
the day the record date is fixed and shall be not more than 90 days and, in the
case of a meeting of shareholders not less than ten days, before the date on
which the meeting or particular action requiring such determination of
shareholders is to be held or taken.

     In lieu of fixing a record date, the Trustees may provide that the
share transfer books shall be closed for a stated period but not longer than 20
days. If the share transfer books are closed for the purpose of determining
shareholders entitled to notice of or to vote at a meeting of shareholders, such
books shall be closed for at lest ten days before the date of such meeting.

     If no record date is fixed and the share transfer books are not closed
for the determination of shareholders, (a) the record date for the determination
of shareholders entitled to notice of or to vote at a meeting of shareholders
shall be at the close of business on the day on which the notice of meeting is
mailed or the 30th day before the meeting, whichever is the closer date to the
meeting; and (b) the record date for the determination of shareholders entitled
to receive payment of a dividend or an allotment of any other rights shall be
the close of business on the day on which the resolution of the Trustees,
declaring the dividend or allotment of rights, is adopted.

     When a determination of shareholders entitled to vote at any meeting of
shareholders has been made as provided in this section, such determination shall
apply to any adjournment thereof, except where the determination has been made
through the closing of the transfer books and the stated period of closing has
expired.


                                      -15-





     Section 5. Share Ledger. The Trust shall maintain at its principal
office or at the office of its counsel, accountants or transfer agent, an
original or duplicate share ledger containing the name and address of each
shareholder and the number of shareholders of each class held by such
shareholder.

     Section 6. Fractional Shares; Issuance of Units. Trustees may issue
fractional shares or provide for the issuance of scrip, all on such terms and
under such conditions as they may determine. Notwithstanding any other provision
of the Declaration or these Bylaws, the Trustees may issue units consisting of
different securities of the Trust. Any security issued in a unit shall have the
same characteristics as any identical securities issued by the Trust, except
that the Trustees may provide that for a specified period securities of the
Trust issued in such unit may be transferred on the books of the Trust only in
such unit.

                                 ARTICLE VIII.

                                 ACCOUNTING YEAR

     The Trustees shall have the power, from time to time, to fix the fiscal
year of the Trust by a duly adopted resolution.

                                    DIVIDENDS

     Section 1. Authorization. Dividends and other distributions upon the
shares of the Trust may be authorized by the Board of Trustees, subject to the
provisions of law and the Declaration of Trust. Dividends may be paid in cash,
property or shares of the Trust, subject to the provisions of law and the
Declaration.

     Section 2. Contingencies. Before payment of any dividends, there may be
set aside out of any funds of the Trust available for dividends such sum or sums
as the Trustees may from time to time, in their absolute discretion, think
proper as the reserve fund for contingencies, for equalizing dividends, for
repairing or maintaining any property of the Trust or for such other purpose as
the Trustees shall determine to be in the best interest of the Trust, and the
Trustees may modify or abolish any such reserve.

                                   ARTICLE X.

                                INVESTMENT POLICY

     Subject to the provisions of the Declaration of Trust, the Trustees may
from time to time adopt, amend, revise or terminate any policy or policies with
respect to investments by the Trust as they shall deem appropriate in their sole
discretion.


                                      -16-





                                  ARTICLE XI.

                                      SEAL

     Section 1. Seal. The Trustees may authorize the adoption of a seal by
the Trust. The seal shall have inscribed thereon the name of the Trust and the
year of its organization. The Trustees may authorize one or more duplicate seals
and provide for the custody thereof.

     Section 2. Affixing Seal. Whenever the Trust is required to place its
seal to a document, it shall be sufficient to meet the requirements of any law,
rule or regulation relating to a seal to place the word "(SEAL)" adjacent to the
signature of the person authorized to execute the document on behalf of the
Trust.

                                  ARTICLE XII.

                                 INDEMNIFICATION

     To the maximum extent permitted by Maryland law in effect from time to
time, the Trust, without requiring a preliminary determination of the ultimate
entitlement to indemnification, shall indemnify (a) any Trustee, officer or
shareholder or any former Trustee, officer or shareholder (including among the
foregoing, for all purposes of this Article XII and without limitation, any
individual who, while a Trustee and at the request of the Trust, serves or has
served as a director, officer, partner or trustee of another corporation,
partnership, joint venture, trust, employee benefit plan or other enterprise),
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
Trustee or officer or any former Trustee or officer against any claim 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 his status as a
shareholder or former shareholder. In addition, the Trust shall pay or
reimburse, in advance of final disposition of a proceeding, reasonable expenses
incurred by a Trustee, officer or shareholder 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, the
Trust 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 indemnification by the Trust as authorized by these Bylaws and
(ii) a written undertaking by him or on his behalf to repay the amount paid or
reimbursed by the Trust if it shall ultimately be determined that the applicable
standard of conduct was not met. The Trust may, with the approval of its
Trustees, provide such indemnification and payment or reimbursement of expenses
to any Trustee, officer or shareholder or any former Trustee, officer or


                                      -17-





shareholder who served a predecessor of the Trust and to any employee or agent
of the Trust or a predecessor of the Trust. Neither the amendment nor repeal of
this Section, nor the adoption or amendment of any other provision of the
Declaration of Trust or these Bylaws inconsistent with this Section, shall apply
to or affect in any respect the applicability of this paragraph with respect to
any act or failure to act which occurred prior to such amendment, repeal or
adoption. Any indemnification or payment or reimbursement of the expenses
permitted by these 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 (the "MGCL") for directors
of Maryland corporations. The Trust may provide to Trustees, officers and
shareholders such other and further indemnification or payment or reimbursement
of expenses as may be permitted by the MGCL, as in effect from time to time, for
directors of Maryland corporations.

                                 ARTICLE XIII.

                                WAIVER OF NOTICE

     Whenever any notice is required to be given pursuant to the Declaration
of Trust or Bylaws or pursuant to applicable law, a waiver thereof in writing,
signed by the person or persons entitled to such notice, whether before or after
the time stated therein, shall be deemed equivalent to the giving of such
notice. Neither the business to be transacted at nor the purpose of any meeting
need be set forth in the waiver of notice, unless specifically required by
statute. The attendance of any person at any meeting shall constitute a waiver
of notice of such meeting, except where such person attends a meeting for the
express purpose of objecting to the transaction of any business on the ground
that the meeting is not lawfully called or convened.

                                  ARTICLE XIV.

                               AMENDMENT OF BYLAWS

     The Trustees shall have the exclusive power to adopt, alter or repeal
any provision of these Bylaws and to make new Bylaws.

     The foregoing are certified as the Bylaws of the Trust, as amended,
approved by the Trustees on June 26, 2001.

                                    AGREEMENT


     This Agreement (this "Agreement") is effective as of December 31, 2001
(the "Effective Date") by and between Anthony A. Nichols, Sr. ("Nichols") and
Brandywine Realty Trust, a Maryland real estate investment trust (the
"Company").

     WHEREAS, Nichols and the Company desire to terminate in its entirety
the Amended and Restated Employment Agreement dated as of December 8, 2000 (the
"Prior Agreement") between Nichols and the Company and to set forth the terms
under which the Company shall employ Nichols from and after the Effective Date,

     NOW, THEREFORE, in consideration of the mutual agreements contained

follows:

     (a) Engagement. The Company hereby engages Nichols as an employee, and
Nichols hereby accepts such engagement by the Company, for the period and upon
the terms and conditions contained in this Agreement.

     (b) Duties.

         (1) During the Term (as defined below), Nichols shall be available to
the Company's President and Chief Executive Officer and Board of Trustees (the
"Board of Trustees") to provide consultation and advice for special research
projects, business development initiatives and strategic planning as and to the
extent requested by, and subject to the direction of, the President and Chief
Executive Officer and Board of Trustees. In addition, during the Term, as and to
the extent requested by and subject to the direction of, the President and Chief
Executive Officer and Board of Trustees, Nichols shall represent the Company in
regional business, community and charity functions. In the performance of his
responsibilities for the Company and its Subsidiaries (as defined below),
Nichols shall not have the authority to bind the Company or its Subsidiaries to
agreements or arrangements and shall not execute documents in the name of the
Company or its Subsidiaries.

         (2) Subject to applicable law, the Company agrees to use commercially
reasonable efforts during the Term to cause Nichols to be nominated for election
to the Board of Trustees at each annual meeting of shareholders of the Company.
Upon the request of a majority of the Trustees, Nichols shall serve as Chairman
of the Board of Trustees and, in such capacity, shall have such authority as may
be vested in such position by the Board of Trustees subject, however, to the
continuing authority of the Board of Trustees to reassign at any time the
position of Chairman to another Trustee. Upon the request of a majority of the
Trustees, Nichols shall serve as a member of the Executive Committee of the
Board of Trustees subject, however, to the continuing authority of the Board of
Trustees to terminate Nichols' membership on the Executive Committee. In his
capacity as a Trustee, Nichols shall carry out his responsibilities in a manner
consistent with applicable law. Unless such compensation is approved by the
Board of Trustees, in its sole discretion, Nichols shall not be entitled to
receive additional compensation on account of his services on the Board of
Trustees or any committee of the Board of Trustees.

                                      -19-





         (3) Nichols shall, upon the request and subject to the direction of the
President and Chief Executive Officer, serve as a director or officer of, or
perform such other duties and services as may be requested for and with respect
to, any of the Company's Subsidiaries. Unless such compensation is also provided
to other inside (employee) directors on account of their service as directors,
Nichols shall not be entitled to receive additional compensation on account of
his services as a director or officer of any Subsidiary of the Company for which
he is requested to serve as a director or officer. As used in this Agreement,
the terms "Subsidiary" and "Subsidiaries" shall mean, with respect to any
entity, any corporation, partnership, limited liability company or other
business entity in which the subject entity has the power (whether by contract,
through securities ownership, or otherwise and whether directly or indirectly
through control of one or more intermediate Subsidiaries) to elect a majority of
board of directors or other governing body, including, in the case of a
partnership, a majority of the board of directors or other governing body of the
general partner.

         (4) The Company shall provide to Nichols during the Term an office and

quality and character as Nichols' secretarial support as of the Effective Date.

     (c) Term. The term of Nichols' employment with the Company shall extend
through 5:00 p.m. on December 31, 2004 or such earlier date as Nichols'
employment shall terminate as provided herein (the "Term"), and upon the

writing, Nichols shall cease to be employed by the Company and its Subsidiaries
in any capacity.

     (d) Periodic Payments. For all of the services rendered by Nichols to the
Company and its Subsidiaries, Nichols shall receive aggregate annual payments of
$360,996. Such payments may be paid, at the election of the Company, either by
the Company or by one or more of its Subsidiaries, in such relative proportions
as the Company may determine, as earned in periodic installments in accordance
with the Company's payroll practices as in effect from time to time. In the
event that Nichols is also employed during any period by a Subsidiary of the
Company, the amount of the payments payable by the Company during such period
shall be reduced by the amount of payments, if any, received by Nichols during
such period from such Subsidiary. Nichols' annual payments shall not be
increased or decreased during the Term.

     (e) Options; Restricted Shares; Loans.

         (1) Options. Pursuant to an award dated January 2, 1998 and (the "1998

exercisable for 678,958 common shares of beneficial interest ("Common Shares")
of the Company. As of the date hereof, the Option is exercisable for 543,166
Common Shares. Nothing in this Agreement shall affect the terms and conditions
of the 1998 Award, which shall continue in force as in effect immediately before
the execution and delivery of this Agreement except that (A) clauses (i) through
(iv), inclusive, of Section 1(a) of the 1998 Award, setting forth the definition
of the term "Expiration Date", are deleted; (B) the term "Change of Control"
means a "Change of Control" within the meaning of Section 17 of the Prior
Agreement , except that, at Nichols' sole discretion, he may elect that the
"Change of Control" definition shall be as set forth in the Brandywine Realty
Trust 1997 Long Term Incentive Plan (the "Plan") (or a successor plan of
comparable intent) as of a date subsequent to the Effective Date.

have vested and the balance remain unvested. The Company and Nichols agree that,

a Loan Agreement dated as of February 18, 2001, as amended and restated as of
April 6, 2001 (the "Loan Agreement"). The principal amount of the Loan and
accrued interest thereon are subject to potential forgiveness on the terms and
conditions set forth in the Loan Agreement. Except as provided in the next
sentence, nothing in this Agreement shall affect the terms and conditions of the
Loan Agreement, (including without limitation Section 6.a), which shall continue
in force as in effect immediately before the execution and delivery of this
Agreement. From and after the Effective Date, in lieu of the provisions in
Sections 6.b and 6.c of the Loan Agreement, the outstanding principal balance of
the Loan, together with accrued interest thereon, shall be subject to
forgiveness as follows: one-half of the outstanding principal balance of the
Loan, together with accrued interest thereon, shall be forgiven on April 1, 2002
and the remaining half, together with accrued interest thereon, shall be
forgiven on April 1, 2003 but only if, on the applicable forgiveness date,
Nichols' employment hereunder has not then terminated hereunder either due to a
termination of Nichols for Cause (as defined in Section 11 below) or Nichols has
not resigned his employment (other than for Good Reason, as defined in Section
12 below).

         (5) Additional Loans. Nichols acknowledges and confirms that as of the
date hereof he owes the Operating Partnership an aggregate of $665,458.32 (plus
accrued interest thereon) on account of two loans made to him by the Operating
Partnership on or about October 10, 1998 and September 30, 1999 in the original
principal amounts of $499,995.25 and $167,100 (the "Additional Loans"). Nichols

force by the Company, Nichols shall be entitled to participate in and receive
the benefits of any retirement plan, health or other employee benefit plan made
generally available to officers of the Company. Payments to Nichols pursuant to
Section 4 hereof shall constitute compensation for purposes of the Company's
retirement, savings and other qualified or non-qualified plans, health and
welfare or other employee benefit programs, if any, and shall be fully benefit
bearing to the extent that his base salary under Section 4 of the Prior
Agreement was so treated. In addition, during the Term, Nichols shall be

negotiation of this Agreement.

         (h) Disability. If the Board of Trustees determines in good faith by a
vote of a majority of its members (other than Nichols) that Nichols is unable to

resulting from a mental or physical illness or injury or any similar cause for a
period of one hundred and twenty (120) consecutive days or for a cumulative

death.

         (j) Change In Control. If Nichols' employment hereunder is terminated

discretion, may terminate Nichols' employment hereunder without Cause and for
any reason or no reason upon 30 days' prior written notice to Nichols at any
time. In the event that Nichols' resigns his employment hereunder with the

Nichols as a termination of his employment hereunder without Cause. "Good
Reason" shall mean (i) a failure by the Company to make the payments required by
Section 4 hereof or other material breach by the Company of this Agreement, (ii)
a Change of Control (as defined in the subsection (B) of Section 5(a) above), or

                              SEPARATION AGREEMENT



                  THIS SEPARATION AGREEMENT is dated as of August 15, 2001 and
is made by and between Jeffrey F. Rogatz ("Rogatz") and BRANDYWINE REALTY TRUST
("BRT"), a Maryland real estate investment trust, having its headquarters at 14

                  WHEREAS, Rogatz serves as Senior Vice President and Chief
Financial Officer of BRT, and holds officer positions with a number of direct
and indirect subsidiaries of BRT;

                  WHEREAS, the parties intend that Rogatz's employment with BRT
and its direct and indirect subsidiaries, including without limitation,
Brandywine Realty Services Corporation ("BRSCO" and, together with BRT and its
other direct and indirect subsidiaries, the "Companies"), will terminate at 5:00
p.m. on August 15, 2001 (the "Effective Time") on an amicable basis.

                  NOW, THEREFORE, Rogatz and BRT, intending to be legally bound,
hereby agree as follows:

                  1. Employment Termination. Rogatz agrees that his employment
with the Companies is terminated, effective as of the Effective Time, and Rogatz
resigns from all positions and offices with the Companies, effective as of the
Effective Time. From and after the Effective Time, the Companies shall have no
obligation to make any payments to, or provide any benefits for, Rogatz on
account of salary, expenses, healthcare or otherwise, other than as and to the
extent provided in Paragraph 2 and other than (a) to pay Rogatz his unpaid
accrued salary and automobile allowance up to the Effective Time, (b) to pay
Rogatz unreimbursed business expenses incurred through the Effective Time (such
amount not to exceed $500 in aggregate), (c) to pay Rogatz the additional sum of
$102,812, which amount represents an agreed upon bonus on account of services by
Rogatz to the Companies during 2001 and prior to the Effective Time and (d)
subject to compliance by Rogatz with his obligations under this Agreement,
including without limitation, Paragraph 11 below, to pay to Rogatz a severance
amount aggregating $39,167, which aggregate severance amount shall be payable
over the period ending on or about October 15, 2001 in accordance with the
Company's normal payroll practices. BRT shall pay or arrange for the payment by
one of the other Companies of the amounts covered by clauses (a), (b) and (c) of
the preceding sentence by no later than 15 days following the Effective Time.
The dollar amounts referred to in the preceding sentence are gross amounts and
do not give effect to required withholdings; all payments made by BRT or one of
the other Companies under this Paragraph 1 and under Paragraph 2 below shall be
net of any required withholding taxes, including withholding taxes required as a
result of other provisions in this Agreement.

                  2.

                  3.

                  4.  Additional Payments.

                                      -28-





                           a. In the event that Rogatz has not accepted
employment with a new employer prior to October 15, 2001 and is in compliance
with all of his obligations under this Agreement, BRT or one of the other
Companies shall continue to make monthly payments to Rogatz in the gross amount
(i.e., before giving effect to deductions for withholdings) of $19,583 per month
in accordance with the Company's normal payroll practices for up to an
additional two and one-half months (such that the aggregate maximum payments
made to Rogatz under this Paragraph 2 do not exceed $48,957), provided that the
foregoing payment obligation shall terminate at such time as Rogatz either
accepts employment with a new employer or fails to comply with any of his
obligations under this Agreement.

                           b. Notwithstanding any prior election or agreement
between Rogatz and the Company to the contrary, and in accordance with Section
7.1(d) of the "Brandywine Realty Trust Executive Deferred Compensation Plan,"
the balance credited to the account of Rogatz thereunder, to the extent vested,
shall be distributed to him in a lump sum after December 31, 2001 and on or
before February 28, 2002, provided that all amounts credited to Rogatz's account
that are attributable to "Additional Company Contributions" pursuant to Section
4.6 of the Plan shall be treated as fully vested.

                  5. Options. Rogatz agrees that all of the options to purchase
common shares of beneficial interest ("Common Shares") awarded to him by BRT,
including without limitation the options awarded to him under the Non-Qualified
Stock Option Award dated January 19, 1999 covering 56,582 Common Shares, and all
rights and privileges contained therein, are terminated in full effective as of
the Effective Time.

                  6. Severance Agreement. Rogatz agrees that the Agreement dated

Effective Time, the vesting restrictions on 3,300 of such Restricted Shares
shall lapse and such Restricted Shares shall become fully vested, and the

none of the 2000 "Restricted Shares" (as defined in the 2001 Restricted Award)
awarded to Rogatz under the Restricted Award have vested. BRT hereby agrees
that, as of the Effective Time, the vesting restrictions on 666 of such
Restricted Shares shall lapse and such Restricted Shares shall become fully
vested, and the remaining 1,334 Restricted Shares shall be forfeited and
surrendered to BRT for cancellation.

                           d. BRT and Rogatz shall cooperate with each other in
the delivery by BRT to Rogatz of a new certificate representing the vested
Restricted Shares to be retained by Rogatz under this Paragraph 5.

                  8. Long-Term Performance Award. Rogatz holds an aggregate of
6,602 Common Shares that he acquired as part of his year-end bonus for 1999, and
566 of these shares are subject to vesting on December 31, 2001 pursuant to
Section 3(c) and Section 4 of the Long-Term Performance Award dated January 2,
2000 between BRT and Rogatz. BRT hereby agrees that, as of the Effective Time,
the vesting restrictions on these 566 shares shall lapse and such shares shall
become fully vested.

                  9. Employee Loans. Rogatz acknowledges and confirms that as of
the Effective Time he owes Brandywine Operating Partnership, L.P. ("BOP") an
aggregate of $435,192.32 (plus interest accrued thereon), reflecting two loans
made to him by BOP on or about January 1999 and September 1999 in the original
principal amounts of $199,996.50 and $245,770.68 (the "Loan"). Rogatz used the
proceeds of the Loan to acquire an aggregate of 26,302 Common Shares.
Notwithstanding the provision in the promissory note (collectively, the "Notes")
evidencing Rogatz's obligation to repay the Loans no later than 90 days
following termination of his employment with the Companies, BRT, in its capacity
as sole general partner of BOP, hereby agrees that Rogatz will have until
December 31, 2001 to repay the principal amount of the Loan; provided, however,
that (i) Rogatz shall continue to be required to pay interest on the Loan at the
times provided in the Note and (ii) in the event that Rogatz sells all or any
portion of the Common Shares acquired by him with proceeds of the Loan, Rogatz
shall be required to use the proceeds of the sale(s) to effect an immediate
repayment of the outstanding principal balance of the Loan, and accrued interest
thereon (with partial prepayments applied first to accrued interest and then to
reduce principal). Until repayment in full of the Loan, and accrued interest
thereon, all Common Shares of Rogatz currently pledged in favor of BOP to secure
repayment of the Loan shall remain so pledged, and upon repayment of the Loan
and accrued interest thereon, BOP shall release its lien on such pledged Common
Shares.

                  10. Confidentiality. Rogatz agrees that he will not disclose
or use, for his direct or indirect benefit or the direct or indirect benefit of
any third party, any non-public information relating to (i) executed and pending
agreements of any of the Companies with third parties (including any potential
agreements that any of the Companies has discussed with third parties), (ii)
contemplated operating strategies of the Companies or (iii) any internal
financial data of the Companies. The agreement of Rogatz in this Paragraph 8
shall terminate on the first anniversary of the Effective Time.


                                      -30-





                  11. Return of Property. Rogatz confirms that he will not
remove from his offices at BRT or use for any purpose after the Effective Time
any files or records of the Companies or any property of the Companies,
including without limitation computers, computer files and data bases,
dictaphones and any other materials, equipment and supplies. Rogatz agrees to
surrender for cancellation as of the Effective Time any credit cards supplied to
him by any of the Companies.

                  12. Non-Solicitation. Until the earlier of (a) 5:00 p.m. on
the date that is the second anniversary of the Effective Time or (b) the
occurrence of a Change of Control (as defined below), Rogatz shall not: (i)
induce or attempt to induce directly or indirectly any employee of any of the
Companies to terminate his or her employment with any of the Companies; (ii)
interfere with the relationship between any of the Companies and their existing
or prospective tenants, including without limitation encouraging a tenant to
terminate, or elect not to renew, its lease with any of the Companies; or (iii)
interfere with the relationship between any of the Companies and any service
providers to any of the Companies; provided that the restriction contained in
this clause (iii) shall not restrict the ability of Rogatz to become employed by
a firm that competes with one of the Companies for a business opportunity. As
used herein, the term "Change of Control" shall have the meaning set forth in
Section 1 of the Brandywine Realty Trust 1997 Long-Term Incentive Plan, as
amended prior to the date hereof.

                  13. Transitional Assistance; Cooperation. Rogatz agrees to
provide full and prompt cooperation to the Companies and their executives in
facilitating an orderly transition with respect to all matters relating to his
responsibilities as an executive of the Companies, including without limitation,
cooperating with respect to matters relating to the Companies' lenders and
shareholders. In furtherance of the foregoing, Rogatz agrees, upon the request
from time to time of BRT's President and Chief Executive Officer (but only in
respect of requests made prior to the later of October 15, 2001 and the date the
obligation of the Companies to make additional payments to Rogatz under
Paragraph 2 terminates on account of his acceptance of new employment), to
attend such meetings at BRT headquarters as the President and Chief Executive
Officer believes to be reasonably necessary to ensure an orderly transition.
Rogatz acknowledges that the obligations of the Companies under clause (d) of
the second sentence of Paragraph 1 and under Paragraph 2 are conditioned upon
compliance by Rogatz with his obligations under this Agreement, including
without limitation, this Paragraph.

                  14. Non-Disparagement. Rogatz agrees that he shall not make
any disparaging, critical or derogatory statements concerning the Companies or
any of their employees, trustees or directors, and BRT, on behalf of itself and
the Companies, agrees that the Companies shall not make any disparaging,
critical or derogatory statements concerning Rogatz. The agreements in this
Paragraph 12 shall terminate on the first anniversary of the Effective Time.

                  15. Waiver and Release of Claims. Rogatz completely releases,
relinquishes, waives and discharges the Companies, its officers, trustees,
directors, employees, agents, successors and assigns from all claims,
liabilities, demands and causes of action, known or unknown, which Rogatz may
have or claim to have against any of the Companies as of the date of the signing
of this Agreement arising out of or in any way related to Rogatz's employment
with any of the Companies or the termination of that employment. Rogatz agrees
that he has executed this release on his own behalf, and also on behalf of

                                      -31-




Rogatz's heirs, agents, representatives, successors and assigns. This release
includes, but is not limited to, a release of any rights or claims Rogatz may
have under: (a) the Age Discrimination in Employment Act, 29 U.S.C. ss.621 et
seq. which prohibits age discrimination in employment; (b) Title VII of the
Civil Rights Act of 1964, as amended by the Civil Rights Act of 1991, 42 U.S.C.
ss.2000(e) et seq., which prohibits discrimination in employment based on race,
color, national origin, religion or sex; (c) the Americans with Disabilities
Act, 42 U.S.C. ss.12101, et seq., which prohibits discrimination on the basis of
a covered disability; (d) the Employee Retirement and Income Security Act, which
prohibits discrimination on the basis of entitlement to certain benefits; (e)
the Family and Medical Leave Act, 29 U.S.C. ss.2601, et seq., which prohibits
discrimination on the basis of entitlement to certain benefits; (f) any other
federal, state or local laws or regulations prohibiting employment
discrimination, including, but not limited to, the New Jersey Law Against
Discrimination and the Pennsylvania Human Relations Act; (g) breach of any
express or implied contract claims; (h) wrongful termination or any other tort
claims, including claims for misrepresentation, defamation, invasion of privacy,
intentional infliction of emotional distress, whether based on common law, or
otherwise; (i) any and all claims for compensatory or punitive damages; and (j)
any and all claims for attorneys' fees and costs.

                  16. Opportunity to Review and Right to Revoke. Rogatz hereby
acknowledges that he is acting of his own free will, that he has been afforded
twenty-one (21) days to read and review the terms of this Agreement, that he has
been advised to seek the advice of counsel, and that he is voluntarily entering
into this Agreement with full knowledge of its respective provisions and
effects. Rogatz also acknowledges that he has seven (7) days following his
signing of this Agreement to revoke this Agreement.

                  17. Third Party Beneficiaries. Each of the direct and indirect
subsidiaries of BRT, including without limitation BRSCO, shall be a third party
beneficiary of this Agreement.

                  18. Acknowledgment; Equitable Relief. Rogatz agrees that the
period of time and the scope of the restrictions in Paragraph 10 of this
Agreement are reasonable. However, if such period of time or scope of
restrictions should be adjudged unreasonable in any judicial proceeding, then
such period of time or scope of restriction shall be reduced to the minimum
extent necessary to make such provisions enforceable. Rogatz agrees that in the
event of a breach by him of Paragraph 8 or 10 the Companies' remedies at law
would be inadequate, and that in addition to such remedies as may be available
to the Companies under law or equity, the Companies shall be entitled to
injunctive relief.

                                      -32-





                  19. Entire Agreement. This Agreement contains the entire
agreement between BRT and Rogatz and supersedes any and all prior and
contemporaneous agreements with respect to the subject matter hereof.

                  20. Governing Law. This Agreement shall be governed by the
laws of the Commonwealth of Pennsylvania.

                  IN WITNESS WHEREOF, Rogatz and BRT have executed this
Agreement as of the date and year first above written.
