                      Common Shares of Beneficial Interest

                             UNDERWRITING AGREEMENT


                                                               February 12, 1998


SMITH BARNEY INC.
388 Greenwich Street
New York, New York 10013

Dear Sirs:

         Brandywine Realty Trust, a Maryland real estate investment trust (the
"Company"), proposes to issue and sell an aggregate of 1,012,820 shares (the
"Shares") of its common shares of beneficial interest, par value $0.01 per share
(the "Common Shares"), to you (the "Underwriter"). The Underwriter intends to
deposit the Shares with the trustee of The Equity Focus Trusts - REIT Portfolio
Series, 1998-A (the "Trust") a registered unit investment trust under the
Investment Company Act of 1940, as amended, to which Smith Barney Inc. acts as
sponsor and depositor, in exchange for units in the Trust.

         The Company, directly and through a wholly-owned subsidiary, is the
sole general partner and a limited partner (with an aggregate 98.709% ownership
interest as of the date hereof, without giving effect to the issuance and sale
of any Shares hereunder) of Brandywine Operating Partnership, L.P., a Delaware
limited partnership (the "Operating Partnership"). The Company will contribute
the net proceeds of the sale of the Shares to the Operating Partnership in
exchange for additional partnership interests in the Operating Partnership. The
Company and the Operating Partnership wish to confirm as follows their agreement
with you, in connection with the purchase of the Shares by the Underwriter.







         1. Registration Statement and Prospectus. The Company has prepared and
filed with the Securities and Exchange Commission (the "Commission") in
accordance with the provisions of the Securities Act of 1933, as amended, and
the rules and regulations of the Commission thereunder (collectively, the
"Act"), a registration statement on Form S-3 (Registration No. 333-39155) under
the Act (the "registration statement"), including a prospectus generally
relating to the Shares; and such amendments, if any, to such registration
statement as may have been required prior to the date hereof have been filed
with the Commission, and such amendments, if any, have been similarly prepared.
Such registration statement and any post-effective amendments thereto have
become effective under the Act. The Company also has filed with the Commission
pursuant to Rule 424(b) under the Act, a prospectus supplement relating to the
Shares dated the date hereof.

         The term "Registration Statement" as used in this Agreement means the
registration statement (including all financial schedules and exhibits), as
amended at the time it became effective, or, if the registration statement
became effective prior to the execution of this Agreement, as supplemented or
amended prior to the execution of this Agreement, including all information (if
any) deemed to be a part of such registration at the time it became effective
pursuant to Rule 430A under the Act. If it is contemplated, at the time this
Agreement is executed, that a post-effective amendment to the registration
statement will be filed and must be declared effective before the offering of
the Shares may commence, the term "Registration Statement" as used in this
Agreement means the registration statement as amended by said post-effective
amendment. The term "Prospectus" as used in this Agreement means the base
prospectus included in the Registration Statement at the time it was declared
effective, or, if the prospectus included in the Registration Statement omits
information in reliance on Rule 430A under the Act and such information is
included in a prospectus filed with the Commission pursuant to Rule 424(b) under
the Act, the term "Prospectus" as used in this Agreement means the prospectus in
the form included in the Registration Statement as supplemented by the addition
of the Rule 430A information contained in the prospectus filed with the
Commission pursuant to Rule 424(b). The term "Prepricing Prospectus" as used in
this Agreement means the prospectus subject to completion in the form included
in the registration statement at the time of the initial filing of the
registration statement with the Commission, and as such prospectus shall have
been amended or supplemented from time to time prior to the date of the
Prospectus. Any reference in this Agreement to the registration statement, the
Registration Statement, any Prepricing Prospectus or the Prospectus shall be
deemed to refer to and include the documents incorporated by reference therein
pursuant to Item 12 of Form S-3 under the Act, as of the date of the
registration statement, the Registration Statement, such Prepricing Prospectus
or the Prospectus, as the case may be, and any reference to any amendment or
supplement to the registration statement, the Registration Statement, any
Prepricing Prospectus or the Prospectus shall be deemed to refer to and include
any documents filed after such date under the Securities Exchange Act of 1934,
as amended (the "Exchange Act") which, upon filing, are incorporated by
reference therein, as required by paragraph (b) of Item 12 of Form S-3. As used
herein, the term "Incorporated Documents" means the documents that at the time
are incorporated by reference in the registration statement, the Registration
Statement, any Prepricing Prospectus, the Prospectus, or any amendment or
supplement thereto. Capitalized terms used, but not defined, herein shall have
the respective meanings ascribed thereto in the Prospectus.

                                       -2-





         2. Agreements to Sell and Purchase. The Company hereby agrees, subject
to all the terms and conditions set forth herein, to issue and sell to the
Underwriter and, upon the basis of the representations, warranties and
agreements of the Company and the Operating Partnership herein contained and
subject to all the terms and conditions set forth herein, the Underwriter agrees
to purchase from the Company, at a purchase price of $22.859375 per Share (the
"Purchase Price per share"), 1,012,820 Shares.

         3. Delivery of the Shares and Payment Therefor. Delivery to the
Underwriter of and payment for the Shares shall be made at the office of Smith
Barney Inc., 388 Greenwich Street, New York, NY 10013, at 10:00 A.M., New York
City time, on February 18, 1998 (the "Closing Date"). The place of closing for
the Shares and the Closing Date may be varied by agreement between the
Underwriter and the Company.

         Certificates for the Shares to be purchased hereunder shall be
registered in such names and in such denominations as you shall request prior to
9:30 A.M., New York City time, on the second business day preceding the Closing
Date. Such certificates shall be made available to you in New York City for
inspection and packaging not later than 9:30 A.M., New York City time, on the
business day next preceding the Closing Date. The certificates evidencing the
Shares to be purchased hereunder shall be delivered to you on the Closing Date
against payment of the purchase price therefor by wire transfer of immediately
available funds to the Company.

         4. Agreements of the Company and the Operating Partnership. The Company
and the Operating Partnership jointly and severally agree with the Underwriter
as follows:

                  (a) If, at the time this Agreement is executed and delivered,
it is necessary for the Registration Statement or a post-effective amendment
thereto to be declared effective before the offering of the Shares may commence,
the Company will endeavor to cause the Registration Statement or such
post-effective amendment to become effective as soon as possible and will advise
you promptly and, if requested by you, will confirm such advice in writing, when
the Registration Statement or such post-effective amendment has become
effective.

                  (b) The Company will advise you promptly and, if requested by
you, will confirm such advice in writing: (i) of any request by the Commission
for amendment of or a supplement to the Registration Statement, any Prepricing
Prospectus or the Prospectus or for additional information; (ii) of the issuance
by the Commission of any stop order suspending the effectiveness of the
Registration Statement or of the suspension of qualification of the Shares for
offering or sale in any jurisdiction or the initiation of any proceeding for
such purpose; and (iii) within the period of time referred to in paragraph (f)
below, of any change in the Company's condition (financial or other), business,
prospects, properties, net worth or results of operations, or of the happening
of any event, which makes any statement of a material fact made in the
Registration Statement or the Prospectus (as then amended or supplemented)
untrue or which requires the making of any additions to or changes in the
Registration Statement or the Prospectus (as then amended or supplemented) in
order to state a material fact required by the Act or the regulations thereunder
to be stated therein or

                                       -3-





necessary in order to make the statements therein not misleading, or of the
necessity to amend or supplement the Prospectus (as then amended or
supplemented) to comply with the Act or any other law. If at any time the
Commission shall issue any stop order suspending the effectiveness of the
Registration Statement, the Company will make every reasonable effort to obtain
the withdrawal of such order at the earliest possible time.

                  (c) The Company will furnish to you, without charge, (i) five
copies of the registration statement as originally filed with the Commission and
of each amendment thereto, including financial statements and all exhibits to
the registration statement, (ii) such number of copies of the Prepricing
Prospectus or Prospectus as you may reasonably request, (iii) such number of
copies of the Incorporated Documents as you may reasonably request, and (iv)
such number of conformed copies of the Registration Statement and of each
amendment thereto, but without exhibits, as you may reasonably request.

                  (d) The Company will not file any amendment to the
Registration Statement or make any amendment or supplement to the Prospectus or,
prior to the end of the period of time referred to in the first sentence of
subsection (f) below, file any document which upon filing becomes an
Incorporated Document, of which you shall not previously have been advised or to
which, after you shall have received a copy of the document proposed to be
filed, you shall object.

                  (e) Prior to the execution and delivery of this Agreement, the
Company has delivered to you, without charge, in such quantities as you have
reasonably requested, copies of each form of the Prepricing Prospectus. The
Company consents to the use, in accordance with the provisions of the Act and
with the securities or Blue Sky or real estate syndication laws of the
jurisdictions in which the Shares are offered by the Underwriter, prior to the
date of the Prospectus, of each Prepricing Prospectus so furnished by the
Company.

                  (f) As soon after the execution and delivery of this Agreement
as possible and thereafter from time to time for such period as in the opinion
of counsel for the Underwriter a prospectus is required by the Act to be
delivered in connection with sales by the Underwriter or dealer, the Company
will expeditiously deliver to each Underwriter and each dealer, without charge,
as many copies of the Prospectus (and of any amendment or supplement thereto) as
you may request. The Company consents to the use of the Prospectus (and of any
amendment or supplement thereto) in accordance with the provisions of the Act
and with the securities or Blue Sky or real estate syndication laws of the
jurisdictions in which the Shares are offered by the Underwriter, both in
connection with the offering and sale of the Shares and for such period of time
thereafter as the Prospectus is required by the Act to be delivered in
connection with sales by an Underwriter or dealer. If during such period of time
any event shall occur that in the judgment of the Company or in the opinion of
counsel for the Underwriter is required to be set forth in the Prospectus (as
then amended or supplemented) or should be set forth therein in order to make
the statements therein, in the light of the circumstances under which they were
made, not misleading, or if it is necessary to supplement or amend the
Prospectus (or to file under the Exchange Act any document which, upon filing,
becomes an Incorporated Document) in order to comply with the Act or any other
law, the

                                       -4-





Company will forthwith prepare and, subject to the provisions of paragraph (d)
above, file with the Commission an appropriate supplement or amendment thereto
(or to such document), and will expeditiously furnish to the Underwriter a
reasonable number of copies thereof. In the event that the Company and you agree
that the Prospectus should be amended or supplemented, the Company, if requested
by you, will promptly issue a press release announcing or disclosing the matters
to be covered by the proposed amendment or supplement.

                  (g) The Company will cooperate with you and with counsel for
the Underwriter in connection with the registration or qualification of the
Shares for offering and sale by the Underwriter under the securities or Blue Sky
or real estate syndication laws of such jurisdictions as you may designate and
will file such consents to service of process or other documents necessary or
appropriate in order to effect such registration or qualification; provided that
in no event shall the Company be obligated to qualify to do business in any
jurisdiction where it is not now so qualified or to take any action which would
subject it to service of process in suits, other than those arising out of the
offering or sale of the Shares, in any jurisdiction where it is not now so
subject.

                  (h) The Company will make generally available to its security
holders a consolidated earnings statement, which need not be audited, covering a
twelve-month period commencing after the effective date of the Registration
Statement and ending not later than 15 months thereafter, as soon as practicable
after the end of such period, which consolidated earnings statement shall
satisfy the provisions of Section 11(a) of the Act.

                  (i) During the period of five years hereafter, the Company
will furnish to you (i) as soon as available, a copy of each report of the
Company mailed to stockholders or filed with the Commission, and (ii) from time
to time such other information concerning the Company as you may reasonably
request.

                  (j) If this Agreement shall terminate or shall be terminated
after execution pursuant to any provisions hereof (otherwise than pursuant to
Section 11 hereof or by notice given by you terminating this Agreement pursuant
to Section 11 or Section 12 hereof) or if this Agreement shall be terminated by
the Underwriter because of any failure or refusal on the part of the Company to
comply with the terms or fulfill any of the conditions of this Agreement, the
Company agrees to reimburse you for all out-of-pocket expenses (including fees
and expenses of counsel for the Underwriter) incurred by you in connection
herewith.

                  (k) The Company will apply the net proceeds from the sale of
the Shares in accordance with the description set forth in the Prospectus.

                  (l) The Company will timely file with the Commission the
Prospectus pursuant to Rule 424(b) under the Act and will advise you of the time
and manner of such filing.

                  (m) Except as stated in this Agreement and in any Prepricing
Prospectus and Prospectus, the Company has not taken, nor will it take, directly
or indirectly, any action designed

                                       -5-






to or that might reasonably be expected to cause or result in stabilization or
manipulation of the price of the Common Shares to facilitate the sale or resale
of the Shares.

         5. Representations and Warranties of the Company. The Company and the
Operating Partnership, jointly and severally, represent and warrant to the
Underwriter that:

                  (a) Each Prepricing Prospectus included as part of the
registration statement as originally filed or as part of any amendment or
supplement thereto, or filed pursuant to Rule 424 under the Act, complied when
so filed in all material respects with the provisions of the Act. The Commission
has not issued any order suspending the effectiveness of the Registration
Statement or any part thereof and no proceeding for that purpose has been
instituted or threatened or, to the best knowledge of the Company, contemplated
by the Commission or the securities authority of any state or other
jurisdiction.

                  (b) The Company and the transactions contemplated by this
Agreement meet the requirements and conditions for using a registration
statement on Form S-3 under the Act. When any Prepricing Prospectus was filed
with the Commission it (i) contained all statements required to be stated
therein in accordance with, and complied in all material respects with the
requirements of, the Act and the rules and regulations of the Commission
thereunder and (ii) did not include any untrue statement of a material fact or
omit to state any material fact necessary in order to make the statements
therein, in the light of the circumstances under which they were made, not
misleading. When the Registration Statement or any amendment thereto was
declared effective, and on the Closing Date it (i) contained or will contain all
statements required to be stated therein in accordance with, and complied or
will comply in all material respects with the requirements of, the Act and the
rules and regulations of the Commission thereunder and (ii) did not or will not
include any untrue statement of a material fact or omit to state any material
fact necessary to make the statements therein not misleading. When the
Prospectus or any amendment or supplement thereto is filed with the Commission
pursuant to Rule 424(b) and at the Closing Date, the Prospectus, as amended or
supplemented at any such time, (i) contained or will contain all statements
required to be stated therein in accordance with, and complied or will comply in
all material respects with the requirements of, the Act and the rules and
regulations of the Commission thereunder and (ii) did not or will not include
any untrue statement of a material fact or omit to state any material fact
necessary in order to make the statements therein, in the light of the
circumstances under which they were made, not misleading. The representations
and warranties in this paragraph (b) do not apply to statements in or omissions
from the Registration Statement or the Prospectus made in reliance upon and in
conformity with information furnished to the Company in writing by or on behalf
of the Underwriter through you expressly for use therein.

                  (c) The Incorporated Documents heretofore filed, when they
were filed (or, if any amendment with respect to any such document was filed,
when such amendment was filed), conformed in all material respects with the
requirements of the Exchange Act and the rules and regulations thereunder, any
further Incorporated Documents so filed will, when they are filed, conform in
all material respects with the requirements of the Exchange Act and the rules
and

                                       -6-






regulations thereunder, no such document when it was filed (or, if an amendment
with respect to any such document was filed, when such amendment was filed),
contained an untrue statement of a material fact or omitted to state a material
fact required to be stated therein or necessary in order to make the statements
therein not misleading and no such further document, when it is filed, will
contain an untrue statement of a material fact or will omit to state a material
fact required to be stated therein or necessary in order to make the statements
therein not misleading.

                  (d) The Company is a real estate investment trust duly formed
and validly existing under and by virtue of the laws of the State of Maryland
and is in good standing with the State Department of Assessments and Taxation of
Maryland, with full trust power and authority to own, lease, and operate its
properties and to conduct its business as described in the Registration
Statement and the Prospectus, and is duly registered and qualified to conduct
its business and is in good standing in each jurisdiction or place where the
nature of its properties or the conduct of its business requires such
registration or qualification, except where the failure to be so registered or
qualified would not have a material adverse effect on the condition (financial
or otherwise), business, prospects, properties, net worth or results of
operations of the Company.

                  (e) Each of the Operating Partnership and the corporations,
limited liability companies, partnerships and limited partnerships listed on
Schedule 5(e) hereto (each, a "Subsidiary") is a corporation, limited
partnership, limited liability company or general partnership duly incorporated
or formed, as the case may be, validly existing and in good standing under the
laws of its jurisdiction of incorporation or formation. Each such entity has
full corporate, limited liability company or partnership power and authority, to
own, lease, and operate its properties, and to conduct its business as described
in the Registration Statement and the Prospectus. Each such Subsidiary is duly
registered and qualified to conduct its business and is in good standing in each
jurisdiction or place where the nature of its properties or the conduct of its
business requires such registration or qualification, except where the failure
to be so registered or qualified would not have a material adverse effect on the
condition (financial or otherwise), business, prospects, properties, net worth
or results of operations of such Subsidiary.

                  (f) All the outstanding Common Shares of the Company have been
duly authorized and validly issued, are fully paid and nonassessable and are
free of any preemptive or similar rights; the Shares have been duly authorized
and, when issued and delivered to the Underwriter against payment therefor in
accordance with the terms hereof, will be validly issued, fully paid and
nonassessable and free of any preemptive or similar rights that entitle or will
entitle any person or entity to acquire any Shares upon the issuance thereof by
the Company, and the beneficial interest of the Company conforms to the
description thereof in the Registration Statement and the Prospectus. Except
with regard to 1997 compensation of non-employee trustees of the Company payable
in Common Shares, awards under the Company's 1997 Long-Term Incentive Plan and
as disclosed in the Prospectus, there are no outstanding options, warrants or
other rights calling for the issuance of, or any commitment, plan or arrangement
to issue, any beneficial interest of the Company or any security convertible
into or exchangeable for beneficial interest of the Company.


                                       -7-






                  (g) All of the outstanding Units and shares of capital stock
or partnership interests in each of the Subsidiaries have been duly authorized
and validly issued or created under the documents or agreements forming such
entity, are fully paid and, in the case of Subsidiaries that are corporations,
nonassessable, and will be owned or be held by the persons and entities in the
percentage amounts set forth and in the manner described in the Prospectus or

                           (2) Except as may be specifically disclosed in the

                           (4) Except as disclosed in the Environmental Reports,
neither the Company nor any Subsidiary has received notice of any occurrence or
circumstance which, with notice or passage of time or both, would give rise to
any claim under or pursuant to any Environmental Law pertaining to hazardous or
toxic waste or substances on or originating from the Properties or arising out
of the conduct of any such party.

                           (5) No environmental engineering firm which prepared

                  (ee) To the knowledge of the Company, all physical condition

         6. Indemnification and Contribution. (a) The Company and the Operating
Partnership, jointly and severally, agree to indemnify and hold harmless the
Underwriter, the directors, officers, employees and agents of the Underwriter,
and each person, if any, who controls the Underwriter within the meaning of
Section 15 of the Act or Section 20 of the Exchange Act from and against any and
all losses, claims, damages, liabilities and expenses (including reasonable
costs of investigation) arising out of or based upon any untrue statement or
alleged untrue statement of a material fact contained in any Prepricing
Prospectus or in the Registration Statement or the Prospectus or in any
amendment or supplement thereto, or arising out of or based upon any omission or
alleged omission to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading, except insofar as
such losses, claims, damages, liabilities or expenses arise out of or are based
upon any untrue statement or omission or alleged untrue statement or omission
which has been made therein or omitted therefrom in reliance upon and in
conformity with the information relating to the Underwriter furnished in writing
to the Company by or on behalf of the Underwriter through you expressly for use
in connection therewith (which information is described in its entirety in
Section 12 below); provided, however, that the indemnification contained in this
paragraph (a) with respect to any Prepricing Prospectus shall not inure to the
benefit of any Underwriter (or to the benefit of any person controlling the
Underwriter) on account of any such loss, claim, damage, liability or expense
arising from the sale of the Shares by the Underwriter to any person if a copy
of the Prospectus shall not have been delivered or sent to such person within
the time required by the Act and the regulations thereunder, and the untrue
statement or alleged untrue statement or omission or alleged omission of a
material fact contained in such Prepricing Prospectus was corrected in the
Prospectus, provided that the Company has delivered the Prospectus to the
Underwriter in requisite quantity on a timely basis to permit such delivery or
sending within the time required by the Act. The foregoing indemnity agreement
shall be in addition to any liability which the Company may otherwise have.

         (b) If any action, suit or proceeding shall be brought against the
Underwriter or any person controlling the Underwriter in respect of which
indemnity may be sought against the Company or the Operating Partnership, the
Underwriter or such controlling person shall promptly notify the Company or the
Operating Partnership, and the Company or the Operating Partnership shall assume
the defense thereof, including the employment of counsel and payment of all fees
and expenses. The

                                      -15-






Underwriter or any such controlling person shall have the right to employ
separate counsel in any such action, suit or proceeding and to participate in
the defense thereof, but the fees and expenses of such counsel shall be at the
expense of the Underwriter or such controlling person unless (i) the Company and
the Operating Partnership have agreed in writing to pay such fees and expenses,
(ii) the Company and the Operating Partnership have failed to assume the defense
and employ counsel, or (iii) the named parties to any such action, suit or
proceeding (including any impleaded parties) include both the Underwriter or
such controlling person and the Company or the Operating Partnership and the
Underwriter or such controlling person shall have been advised by its counsel
that representation of such indemnified party and the Company or the Operating
Partnership by the same counsel would be inappropriate under applicable
standards of professional conduct (whether or not such representation by the
same counsel has been proposed) due to actual or potential differing interests
between them (in which case the Company and the Operating Partnership shall not
have the right to assume the defense of such action, suit or proceeding on
behalf of such Underwriter or such controlling person). It is understood,
however, that the Company shall, in connection with any one such action, suit or
proceeding or separate but substantially similar or related actions, suits or
proceedings in the same jurisdiction arising out of the same general allegations
or circumstances, be liable for the reasonable fees and expenses of only one
separate firm of attorneys (in addition to any local counsel) at any time for
the Underwriter and controlling persons not having actual or potential differing
interests with you or among themselves, which firm shall be designated in
writing by the Underwriter, and that all such fees and expenses shall be
reimbursed as they are incurred. The Company and the Operating Partnership shall
not be liable for any settlement of any such action, suit or proceeding effected
without its written consent, but if settled with such written consent, or if
there shall be a final judgment for the plaintiff in any such action, suit or
proceeding, the Company and the Operating Partnership agree to indemnify and
hold harmless the Underwriter, to the extent provided in the preceding
paragraph, and any such controlling person from and against any loss, claim,
damage, liability or expense by reason of such settlement or judgment.

         (c) The Underwriter agrees to indemnify and hold harmless the Company,
its trustees and officers who sign the Registration Statement, and any person
who controls the Company within the meaning of Section 15 of the Act or Section
20 of the Exchange Act, to the same extent as the foregoing indemnity from the
Company and the Operating Partnership to the Underwriter, but only with respect
to losses, claims, damages, liabilities and expenses arising out of or based on
information relating to the Underwriter furnished in writing by or on behalf of
the Underwriter through you expressly for use in the Registration Statement, the
Prospectus or any Prepricing Prospectus or any amendment or supplement thereto.
If any action, suit or proceeding shall be brought against the Company, any of
its directors or officers, or any such controlling person based on the
Registration Statement, the Prospectus or any Prepricing Prospectus, or any
amendment or supplement thereto, and in respect of which indemnity may be sought
against the Underwriter pursuant to this paragraph (c), the Underwriter shall
have the rights and duties given to the Company and the Operating Partnership by
paragraph (b) above (except that if the Company or the Operating Partnership
shall have assumed the defense thereof such Underwriter shall not be required to
do so, but may employ separate counsel therein and participate in the defense
thereof, but the fees and expenses of such counsel shall be at the Underwriter's
expense), and the Company, its trustees and officers, and any

                                      -16-






such controlling person shall have the rights and duties given to the
Underwriter by paragraph (b) above. The foregoing indemnity agreement shall be
in addition to any liability which the Underwriter may otherwise have.

         (d) If the indemnification provided for in this Section 6 is
unavailable to an indemnified party under paragraphs (a) or (c) hereof in
respect of any losses, claims, damages, liabilities or expenses referred to
therein, then an indemnifying party, in lieu of indemnifying such indemnified
party, shall contribute to the amount paid or payable by such indemnified party
as a result of such losses, claims, damages, liabilities or expenses (i) in such
proportion as is appropriate to reflect the relative benefits received by the
Company and the Operating Partnership, on the one hand, and the Underwriter, on
the other hand, from the offering of the Shares, or (ii) if the allocation
provided by clause (i) above is not permitted by applicable law, in such
proportion as is appropriate to reflect not only the relative benefits referred
to in clause (i) above but also the relative fault of the Company and the
Operating Partnership, on the one hand, and the Underwriter, on the other, in
connection with the statements or omissions that resulted in such losses,
claims, damages, liabilities or expenses, as well as any other relevant
equitable considerations. The relative benefits received by the Company and the
Operating Partnership, on the one hand, and the Underwriter, on the other, shall
be deemed to be in the same proportion as the total net proceeds from the
offering (before deducting expenses) received by the Company and the Operating
Partnership bear to the total underwriting discounts and commissions received by
the Underwriter, in each case as set forth in the table on the cover page of the
Prospectus. The relative fault of the Company on the one hand and the
Underwriter on the other hand shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Company on the one hand or by the Underwriter on the other hand
and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission.

         (e) The Company, the Operating Partnership and the Underwriter agree
that it would not be just and equitable if contribution pursuant to this Section
6 were determined by a pro rata allocation or by any other method of allocation
that does not take account of the equitable considerations referred to in
paragraph (d) above. The amount paid or payable by an indemnified party as a
result of the losses, claims, damages, liabilities and expenses referred to in
paragraph (d) above shall be deemed to include, subject to the limitations set
forth above, any legal or other expenses reasonably incurred by such indemnified
party in connection with investigating any claim or defending any such action,
suit or proceeding. Notwithstanding the provisions of this Section 6, the
Underwriter shall not be required to contribute any amount in excess of the
amount by which the total price of the Shares underwritten by it exceeds the
amount of any damages which such Underwriter has otherwise been required to pay
by reason of such untrue or alleged untrue statement or omission or alleged
omission. No person guilty of fraudulent misrepresentation (within the meaning
of Section 11(f) of the Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.


                                      -17-






         (f) No indemnifying party shall, without the prior written consent of
the indemnified party, effect any settlement of any pending or threatened
action, suit or proceeding in respect of which any indemnified party is or could
have been a party and indemnity could have been sought hereunder by such
indemnified party, unless such settlement includes an unconditional release of
such indemnified party from all liability on claims that are the subject matter
of such action, suit or proceeding.

         (g) Any losses, claims, damages, liabilities or expenses for which an
indemnified party is entitled to indemnification or contribution under this
Section 6 shall be paid by the indemnifying party to the indemnified party as
such losses, claims, damages, liabilities or expenses are incurred. The
indemnity and contribution agreements contained in this Section 6 and the
representations and warranties of the Company and the Operating Partnership set
forth in this Agreement shall remain operative and in full force and effect,
regardless of (i) any investigation made by or on behalf of the Underwriter or
any person controlling the Underwriter, the Company and its trustees or
officers, the Operating Partnership and its officers, or any person controlling
the Company or the Operating Partnership, (ii) acceptance of any Shares and
payment therefor hereunder, and (iii) any termination of this Agreement. A
successor to the Underwriter or any person controlling the Underwriter, or to
the Company and its trustees or officers, the Operating Partnership and its
officers, or any person controlling the Company or the Operating Partnership,
shall be entitled to the benefits of the indemnity, contribution, and
reimbursement agreements contained in this Section 6.

         7. Conditions of Underwriter's Obligations. The obligation of the
Underwriter to purchase the Shares hereunder are subject to the following
conditions:

                  (a) If, at the time this Agreement is executed and delivered,
it is necessary for the registration statement or a post-effective amendment

effective not later than 5:30 P.M., New York City time, on the date hereof, or
at such later date and time as shall be consented to in writing by you, and all
filings, if any, required by Rules 424 and 430A under the Act shall have been
timely made; no stop order suspending the effectiveness of the registration
statement shall have been issued and no proceeding for that purpose shall have
been instituted or, to the knowledge of the Company or any Underwriter,
threatened by the Commission, and any request of the Commission for additional
information (to be included in the Registration Statement or the Prospectus or
otherwise) shall have been complied with to your satisfaction.

                  (b) Subsequent to the effective date of this Agreement, there
shall not have occurred (i) any change, or any development involving a
prospective change, in or affecting the condition (financial or other),
business, prospects, properties, net worth, or results of operations of the
Company or the Subsidiaries not contemplated by the Prospectus, which in your
opinion would materially, adversely affect the market for the Shares, or (ii)
any event or development relating to or involving the Company or any officer or
trustee of the Company or the Operating Partnership which makes any statement
made in the Prospectus untrue or which, in the opinion of the Company and its

                                      -18-






counsel or the Underwriter and their counsel, requires the making of any
addition to or change in the Prospectus in order to state a material fact
required by the Act or any other law to be stated therein or necessary in order
to make the statements therein, in light of the circumstances in which they were
made, not misleading, if amending or supplementing the Prospectus to reflect
such event or development would, in your opinion, materially, adversely affect
the market for the Shares.

                  (c) You shall have received on the Closing Date, the opinion
of Pepper Hamilton LLP, counsel for the Company, the Operating Partnership and
the other Subsidiaries, dated the Closing Date and addressed to you, in the form
set forth on Exhibit 7(c) attached hereto.

                  In rendering their opinion as aforesaid, such counsel may rely
upon an opinion or opinions, each dated the Closing Date, of other counsel
retained by them or the Company as to laws of any jurisdiction other than the
United States, the State of New York, the Commonwealth of Pennsylvania and the
State of Delaware, provided that (1) each such local counsel is reasonably
acceptable to you, (2) such reliance is expressly authorized by each opinion so
relied upon and a copy of each such opinion is delivered to you and is, in form
and substance, satisfactory to you and your counsel, and (3) such counsel shall
state in their opinion that they believe that they and the Underwriter are
justified in relying thereon.

                  (d) You shall have received on the Closing Date an opinion of
Arthur Andersen LLP, special tax advisor to the Company, satisfactory in form
and substance to you, to the effect that (i) the descriptions of the Federal
income tax conclusions contained in the Prospectus under the caption "Federal
Income Tax Considerations" are correct in all material respects, and the
discussion contained therein fairly summarizes the Federal income tax
considerations that may be material to a holder of the common shares; (ii)
assuming the Company is operated in accordance with the assumptions and
representations of management regarding its activities and intended activities,
the Company will continue to qualify as a REIT under the Code; and (iii) the
Operating Partnership and the Title Holding Partnerships will be treated for
Federal income tax purposes as partnerships and not as associations taxable as
corporations or as publicly-traded partnerships.

                  (e) You shall have received on the Closing Date an opinion of
Battle Fowler LLP, counsel for the Underwriter, dated the Closing Date and
addressed to you, with respect to the Registration Statement, the Prospectus and
this Agreement and such other related matters as you may request.

                  (f) You shall have received comfort letters, including, but
not limited to, certain agreed upon procedures, addressed to you and dated the
date hereof and the Closing Date from Arthur Andersen LLP and Zelenkofske

purpose shall have been taken or, to the knowledge of the Company or the
Underwriter, shall be contemplated by the Commission at or prior to the

                                      -19-






Closing Date; (ii) there shall not have been any change in the beneficial
interest of the Company nor any material increase in the short-term or long-term
debt of the Company (other than in the ordinary course of business) from that
set forth or contemplated in the Registration Statement or the Prospectus (or
any amendment or supplement thereto); (iii) there shall not have been, since the
respective dates as of which information is given in the Registration Statement
and the Prospectus (or any amendment or supplement thereto), except as may
otherwise be stated in the Registration Statement and Prospectus (or any
amendment or supplement thereto), any material adverse change in the condition
(financial or other), business, prospects, properties, net worth or results of
operations of the Properties or the Company and the Subsidiaries taken as a
whole; (iv) the Company and the Subsidiaries shall not have any liabilities or
obligations, direct or contingent (whether or not in the ordinary course of
business), that are material to the Company and the Subsidiaries, taken as a
whole, other than those reflected in the Registration Statement or the
Prospectus (or any amendment or supplement thereto); and (v) all the
representations and warranties of the Company and the Operating Partnership
contained in this Agreement shall be true and correct on and as of the date
hereof and on and as of the Closing Date as if made on and as of the Closing
Date, and you shall have received a certificate, dated the Closing Date and

                  (h) The Company shall not have failed at or prior to the

                  (j) The Company and the Operating Partnership shall have
furnished or caused to be furnished to you such further certificates and
documents as you shall have reasonably requested.

         All such opinions, certificates, letters and other documents will be in
compliance with the provisions hereof only if they are satisfactory in form and
substance to you and your counsel.

         Any certificate or document signed by any officer of the Company and
the Operating Partnership and delivered to you, or to counsel for the
Underwriter, shall be deemed a representation and warranty by the Company or the
Operating Partnership, as applicable, to each Underwriter as to the statements
made therein.

and all other costs and expenses incident to the performance by it of its

the time this Agreement is executed and delivered, it is necessary for the

the effectiveness of the Registration Statement or such post-effective amendment
has been released by the Commission. Until such time as this Agreement shall
have become effective, it may be terminated by the Company, by notifying you, or

general moratorium on commercial banking activities in New York or Pennsylvania

                                      -21-






financial markets of the United States is such as to make it, in your judgment,
impracticable or inadvisable (x) to commence or continue the offering of the
units of the Trust to the public, or (y) to enforce contracts for the sale of
the units of the Trust. Notice of such termination may be given to the Company
by telegram, telecopy or telephone and shall be subsequently confirmed by

Executive Officer; or (ii) if to you, in care of Smith Barney Inc., 388

contracts made and to be performed within the State of New York.

         This Agreement may be signed in various counterparts which together
