         Partnership and its subsidiaries (the "Subsidiaries") and their
         business has been or will be so prepared and will be filed pursuant to
         Rule 424(b) of the Rules and Regulations on or before the second

         or any amendment thereto became effective under the Act (the "Effective
         Date"), including all information contained in the final prospectus
         filed with the Commission pursuant to Rule 424(b) of the Rules and
         Regulations and deemed to be a part of the Second Registration

         Act") after the Effective Date of the Second Registration Statement and
         incorporated by reference in the Prospectus shall be deemed to


                                       -2-

         be included in the Registration Statement and the Prospectus as of the
         date of such filing. The term "Prospectus" as used herein means the
         Prospectus Supplement and the related prospectus supplemented by such
         Prospectus Supplement (including, in the case of such prospectus, the
         documents incorporated by reference therein pursuant to Item 12 of Form
         S-3 under the Act as of the date of the Prospectus Supplement and the
         Closing Date, as the case may be). The term "Preliminary Prospectus" as
         used herein shall mean the preliminary prospectus included in the
         Second Registration Statement.

                  (ii) The Commission has not issued, and is not to the
         knowledge of the Company or the Operating Partnership threatening to
         issue, an order preventing or suspending the use of any Preliminary
         Prospectus or the Prospectus, nor has the Commission, to the knowledge
         of the Company or the Operating Partnership, instituted proceedings for
         that purpose. Each Preliminary Prospectus at its date of issue, the
         Registration Statement at its Effective Date, and the Prospectus at its
         date of issue and any amendments or supplements thereto contains or
         will contain, as the case may be, all statements which are required to
         be stated therein by, and in all material respects conform or will
         conform, as the case may be, to the requirements of, the Act and the
         Rules and Regulations. Neither the Registration Statement nor any
         amendment thereto, as of the applicable Effective Date, and neither the
         Prospectus nor any supplement thereto, as of its applicable issue date
         or the Closing Date, contains or will contain, as the case may be, any
         untrue statement of a material fact, or omits or will omit to state any
         material fact required to be stated therein or necessary to make the
         statements therein, in the light of the circumstances under which they
         were made, not misleading; provided, however, that the Company and the
         Operating Partnership make no representation or warranty as to
         information contained in or omitted from the Registration Statement or
         the Prospectus, or any such amendment or supplement, in reliance upon,
         and in conforming with, written information furnished to the Company by
         you specifically for use in the preparation thereof.

                  (iii) The documents incorporated by reference in the
         Prospectus pursuant to Item 12 of Form S-3 under the Act, at the time
         they were filed with the Commission, complied in all material respects
         with the requirements of the Exchange Act, and the rules and
         regulations adopted by the Commission thereunder (the "1934 Act Rules
         and Regulations"), and, when read together and with the other
         information in the Prospectus, at the time the applicable Registration
         Statement became effective and at the Closing Date, did not or will
         not, as the case may be, contain an untrue statement of a material fact
         or omit to state a material fact required to be stated therein or
         necessary to make the statements therein not misleading.

         the execution and delivery of this Agreement by the Company and the
         Operating Partnership have been duly authorized by the Board of
         Trustees of the Company; this Agreement constitutes a valid and legally
         binding obligation of the Company and the Operating Partnership
         enforceable in accordance with its terms (except to the extent the
         enforceability of the indemnification and contribution provisions of
         Section 6 hereof may be limited by public policy considerations as
         expressed in the Act as construed by courts of competent jurisdiction,
         and except as enforceability may be limited by bankruptcy, insolvency,
         reorganization, moratorium and other laws affecting creditors' rights
         generally and by general principles of equity); the issue and sale of
         the Shares by the Company and the performance of this Agreement and the
         consummation of the transactions herein contemplated will not result in
         a violation of the Company's declaration of trust or bylaws or the
         Operating Partnership's agreement of limited partnership, each as
         amended to the date hereof or the Closing Date, as the case may be, or
         result in a breach or violation of any of the terms and provisions of,
         or constitute a default under, or result in the creation or imposition
         of any lien, charge or encumbrance upon any properties or assets of the
         Company or of the Operating Partnership or the Subsidiaries under, any
         statute, or under any indenture, mortgage, deed of trust, note, loan
         agreement, sale and leaseback arrangement or other agreement or
         instrument to which any of the Company, the Operating Partnership or
         the Subsidiaries is a party or by which they are bound or to which any
         of the properties or assets of the Company, the Operating Partnership
         or the Subsidiaries is subject, or any order, rule or regulation of any
         court or governmental agency or body having jurisdiction over the
         Company, the Operating Partnership or the Subsidiaries or their
         properties, except to such extent as does not materially adversely
         affect the business of the Company, the Operating Partnership and the
         Subsidiaries taken as a whole; no consent, approval, authorization,
         order, registration or qualification of or with any court or
         governmental agency or body is required for the consummation of the
         transactions herein contemplated, except such as may be required by the
         National Association of Securities Dealers, Inc. (the "NASD"), the New
         York Stock Exchange, Inc. or under the Act or the Rules and Regulations
         or any state securities laws.

                  (v) Neither the Company, nor the Operating Partnership or any
         of the Subsidiaries, taken as a whole, has sustained since the date of
         the latest audited financial statements included or incorporated by
         reference in the Prospectus any material loss or interference with its
         business from fire, explosion, flood or other calamity, whether or not
         covered by insurance, or from any labor dispute or court or
         governmental action, order or decree. Except as contemplated in the

         entered into any material transactions not in the ordinary course of
         business, and there has not been any material change in the capital
         stock or long-term debt of the Company and the Units of limited
         partnership interest (the "Units") or long-term debt of the Operating
         Partnership and the Subsidiaries, taken as a whole, or any material

         Partnership and the Subsidiaries, taken as a whole; the Company, the
         Operating Partnership and the Subsidiaries have made all necessary
         payroll tax payments and are current and up-to-date as of the date of

         pending or, to the knowledge of the Company or the Operating
         Partnership, threatened or contemplated, any action, suit or proceeding
         to which any of the Company, the Operating Partnership or the
         Subsidiaries is a party before or by any court or public, regulatory or
         governmental agency or body which might be expected to result
         (individually or in the aggregate) in any material adverse change in
         the condition (financial or other), business or prospects of the
         Company, the Operating Partnership and the Subsidiaries, taken as a
         whole, or might be expected to materially and adversely affect
         (individually or in the aggregate) the properties or assets thereof,
         taken as a whole, and there are no contracts or documents of the
         Company, the Operating Partnership and the Subsidiaries which are
         required to be filed as exhibits to the applicable Registration
         Statement by the Act or by the Rules and Regulations which have not
         been filed as exhibits to the applicable Registration Statement or
         incorporated by reference therein.

                  (vii) The Company has duly and validly authorized Common
         Shares as described in the Prospectus; all outstanding Common


                                       -5-
   6
         Shares conform, and the Shares, when issued will conform, to the
         description thereof in the Prospectus and have been, or, when issued
         and paid for will be, duly authorized, validly issued, fully paid and
         nonassessable; and the issuance of the Shares to be purchased from the
         Company hereunder is not subject to preemptive rights.

                  (viii) Each of the Company, the Operating Partnership and the
         Subsidiaries has been duly incorporated or formed, as the case may be,
         and is a validly existing corporation, real estate investment trust or
         limited partnership, or other legal entity, as the case may be, in good
         standing under the laws of the state or other jurisdiction in which it
         is incorporated or formed, as the case may be. The Company, the
         Operating Partnership and the Subsidiaries have full power and
         authority to own, lease and operate their properties and conduct their
         businesses as described in the Prospectus; each of the Company, the
         Operating Partnership and the Subsidiaries is duly qualified or
         registered to do business and is in good standing in each state or
         other jurisdiction in which its ownership or leasing of property or
         conduct of business legally requires such qualification, except where
         the failure to be so qualified would not have a material adverse effect
         on the ability of the Company and the Operating Partnership, considered
         as a single enterprise, to conduct their business as described in the
         Prospectus; and the outstanding shares of capital stock or ownership
         interests of the Subsidiaries have been duly authorized and validly
         issued, are fully paid and nonassessable and are owned by the Operating
         Partnership free and clear of any mortgage, pledge, lien, encumbrance,
         charge or adverse claim and are not the subject of any agreement or
         understanding with any person, except as set forth in the Prospectus.

                  (ix) Ernst & Young LLP, the accounting firm which has
         certified the financial statements incorporated by reference in the
         Prospectus and forming a part of the Registration Statement, are
         independent public accountants as required by the Act and the Rules and
         Regulations.

                  (x) The consolidated financial statements of the Company
         together with the related schedules and notes thereto, set forth or
         included or incorporated by reference in the Registration Statement and
         Prospectus fairly present the consolidated financial condition of the
         Company as of the dates indicated and the consolidated results of
         operations, shareholders' equity and cash flows for the periods therein
         specified, in conformity with generally accepted accounting principles
         consistently applied throughout the periods involved (except as
         otherwise stated therein). The summary and selected financial and
         statistical data included or incorporated by reference in the
         Registration Statement and the Prospectus present fairly the
         information shown therein and, to the extent based upon or derived from
         the financial


                                       -6-
   7
         statements, have been compiled on a basis consistent with the financial
         statements presented therein. In addition, the pro forma financial
         statements of the Company, and the related notes thereto, included or
         incorporated by reference in the Registration Statement and the
         Prospectus present fairly the information shown therein, have been
         prepared in accordance with the Commission's rules and guidelines with
         respect to pro forma financial statements and have been properly
         compiled on the basis described therein, and the assumptions used in
         the preparation thereof are reasonable and the adjustments used therein
         are appropriate to give effect to the transactions and circumstances
         referred to therein. Furthermore, all financial statements required by
         Rule 3-14 of Regulation S-X ("Rule 3-14") have been included or
         incorporated by reference in the Registration Statement and the
         Prospectus and any such financial statements are in conformity with the
         requirements of Rule 3-14. No other financial statements are required
         to be set forth or to be incorporated by reference in the Registration
         Statement or the Prospectus under the Act or the Rules and Regulations
         thereunder.

                  (xi) Neither the Company, the Operating Partnership nor any of
         the Subsidiaries is in default with respect to any contract or
         agreement to which it is a party; provided that this representation
         shall not apply to defaults which in the aggregate are not materially
         adverse to the condition, financial or other, or the business or
         prospects of the Company, the Operating Partnership and the
         Subsidiaries, taken as a whole.

                  (xii) Neither the Company, the Operating Partnership nor the
         Subsidiaries is in violation of any laws, ordinances or governmental
         rules or regulations to which it is subject, including, without
         limitation, Section 13 of the Exchange Act, and neither the Company,
         the Operating Partnership nor any of the Subsidiaries has failed to
         obtain any license, permit, franchise, easement, consent, or other
         governmental authorization necessary to the ownership, leasing and
         operation of its properties or to the conduct of its business, which
         violation or failure would materially adversely affect the business,
         operations, affairs, properties, prospects, profits or condition
         (financial or other) of the Company, the Operating Partnership and the
         Subsidiaries, taken as a whole. Neither the Company, the Operating
         Partnership nor the Subsidiaries has, at any time during the past five
         years, (A) made any unlawful contributions to any candidate for any
         political office, or failed fully to disclose any contribution in
         violation of law, or (B) made any payment to any state, federal or
         foreign government official, or other person charged with similar
         public or quasi-public duty (other than payments required or permitted
         by applicable law).

                  (xiii) There are no holders of securities of the Company
         having rights to registration thereof or preemptive rights to


                                       -7-
   8
         purchase Common Shares except as disclosed in the Prospectus and
         registration rights of persons whose securities have been registered
         under the Act. Holders of any such registration rights have waived such
         rights with respect to the offering being made by the Prospectus.

                  (xiv) Except as described in the Prospectus, the Company, the
         Operating Partnership and the Subsidiaries own or possess, or can
         acquire on reasonable terms, adequate patents, patent licenses,
         trademarks, service marks and trade names necessary to conduct the
         business now operated by them, and neither the Company nor the
         Operating Partnership or the Subsidiaries has received any notice of
         infringement of or conflict with asserted rights of others with respect
         to any patents, patent licenses, trademarks, service marks or trade
         names which, singly or in the aggregate, if the subject of an
         unfavorable decision, ruling or finding, would have a material adverse
         effect on the conduct of the business, operations, financial condition
         or income of the Company, the Operating Partnership and the
         Subsidiaries, taken as a whole.

                  (xv) The Company, the Operating Partnership and each of the
         Subsidiaries have good and marketable title to all properties and
         assets described in the Prospectus as owned by them, free and clear of
         all liens, charges, encumbrances or restrictions, except such as (i)
         are described in the Prospectus or (ii) are not material to the
         business of the Company, the Operating Partnership and the
         Subsidiaries, taken as a whole. The Company, the Operating Partnership
         and each of the Subsidiaries have valid, subsisting and enforceable
         leases for the properties described in the Prospectus as leased by one
         of them as lessee, with such exceptions as are not material and do not
         materially interfere with the use made and proposed to be made of such
         properties by the Company, the Operating Partnership and such
         Subsidiaries; to the knowledge of the Company and the Operating
         Partnership, the use and occupancy of each of the properties of the
         Company and the Operating Partnership complies in all material respects
         with all applicable codes and zoning laws and regulations, except for
         such failures to comply that would not have a material adverse effect
         on the business operations, use or value of such property; neither the
         Company nor the Operating Partnership has knowledge of any pending or
         threatened condemnation or zoning change that will in any material
         respect affect the size of, use of, improvements of, construction on,
         or access to any of the properties of the Company and the Operating
         Partnership or knowledge of any pending or threatened proceeding or
         action that will in any manner material to the business of the Company
         and the Operating Partnership, taken as a whole, affect the size of,
         use of, improvements on, construction on, or access to any of the
         properties of the Company and the Operating Partnership.

                  (xvi) Title insurance in favor of the Company or the


                                       -8-
   9
         Operating Partnership (or the Subsidiary that holds title to such
         property) is maintained with respect to each of the properties owned by
         the Company or the Operating Partnership in an amount at least equal to
         the greater of (i) the cost of acquisition of such property of (ii) the
         cost of construction by the Company or the Operating Partnership of the
         improvements located on such property (measured at the time of such
         construction), except, in each case, where the failure to maintain such
         title insurance would not have a material adverse effect on the
         condition, financial or otherwise, or the earnings, business affairs or
         business prospects of the Company and the Operating Partnership, taken
         as a whole. Title insurance in favor of the mortgagee with respect to
         properties mortgaged by the Company, the Operating Partnership or any
         Subsidiary is maintained in an amount equal to the maximum commitment
         by such mortgagee of the related mortgage loan.

                  (xvii) (a) Except as disclosed in the Prospectus, each of the
         Company and the Operating Partnership has no knowledge of (a) the
         presence of any hazardous substances, Hazardous Materials (defined
         below) on any of its properties, except that which is in compliance
         with all applicable Environmental Laws (as hereinafter defined) or (b)
         any spills, releases, discharges or disposals of Hazardous Materials
         that have occurred or are presently occurring on or from its
         properties, which presence or occurrence would individually or in the
         aggregate have a material adverse effect on the conduct of the
         business, operations, financial condition or income of the Company, the
         Operating Partnership and the Subsidiaries taken as a whole.

                  (b) Except as disclosed in the Prospectus, each of the
         Company, the Operating Partnership and the Subsidiaries and their
         properties (i) are in compliance with all applicable Environmental
         Laws, (ii) have received all permits, licenses or other approvals
         required under applicable Environmental Laws to conduct its business
         and (iii) are in compliance with all terms and conditions of any such
         permit, license or approval, except where such noncompliance with
         Environmental Laws, failure to receive required permits, licenses or
         other approvals or failure to comply with the terms and conditions of
         such permits, licenses or approvals would not individually or in the
         aggregate have a material adverse effect on the conduct of the
         business, operations, financial condition or income of the Company, the
         Operating Partnership and the Subsidiaries taken as a whole.

                  (c) The Operating Partnership or the Company has engaged
         environmental consultants to perform phase I environmental site
         assessments in general accordance with the ASTM Standard to identify
         any "recognized environmental conditions" (as defined in the ASTM
         Standard prior to the purchase of properties by the Operating
         Partnership or the Company. On


                                       -9-
   10
         the basis of such phase I environmental site assessments, or such
         additional investigations as may have been performed based on the
         findings of a phase I assessment, and, except as described in the
         Prospectus, the Company and the Operating Partnership have reasonably
         concluded that no such recognized environmental conditions exist which
         would, individually or in the aggregate, have a material adverse effect
         on the conduct of the business, operations, financial condition or
         income of the Company, the Operating Partnership and the Subsidiaries
         taken as a whole.

                  (d) As used herein, "Hazardous Material" shall mean substances
         defined or listed as "hazardous substances," "toxic substances,"
         "hazardous waste," "hazardous materials" or "pollutants" in or under
         any applicable Federal, state or local law relating to the protection
         of public health and the environment, including, without limitation,
         any flammable explosives, radioactive materials, asbestos,
         polychlorinated biphenyls ("PCBs") and petroleum products and
         by-products.

                  (e) As used herein, "Environmental Law" shall mean all laws,
         regulations or ordinances of any Federal, state or local governmental
         authority having or claiming jurisdiction over any of the Properties (a
         "Governmental Authority") that are designed to protect public health
         and the environment or regulate the handling of Hazardous Materials,
         including, without limitation, the Comprehensive Environmental
         Response, Compensation, and Liability Act of 1980, as amended (42
         U.S.C. Section 9601 et seq.) ("CERCLA"), the Hazardous Materials
         Transportation Act, as amended (49 U.S.C. Section 5101 et seq.), the
         Resource Conservation and Recovery Act, as amended (42 U.S.C. Section
         6901 et seq.), the Federal Water Pollution Control Act, as amended (33
         U.S.C. Section 1251 et seq.), and the Clean Air Act, as amended (42
         U.S.C. Section 7401 et seq.), and any and all analogous state or local
         laws.

                  (xviii) No labor disturbance exists with the employees of the
         Company, the Operating Partnership or the Subsidiaries or, to the
         knowledge of the Company and the Operating Partnership, is imminent
         which would have a material adverse effect on the Company, the
         Operating Partnership and the Subsidiaries taken as a whole.

                  (xix) The Company has not taken and will not take, directly or
         indirectly, any action designed to or which might reasonably be
         expected to cause or result in stabilization or manipulation of the
         price of the Common Shares, and the Company is not aware of any such
         action taken or to be taken by affiliates of the Company.

                  (xx) Neither the Company nor the Operating Partnership is an
         "investment company" or a company "controlled" by an "investment
         company" within the meaning of the Investment Company Act of 1940, as
         amended.


                                      -10-
   11
                  (xxi) The mortgages and deeds of trust encumbering the
         properties and assets of the Company, the Operating Partnership and the
         Subsidiaries described in the Prospectus are not convertible into
         equity securities of the respective entity that owns such properties
         and assets.

                  (xxii) Property and casualty insurance in favor of the Company
         or the Operating Partnership is maintained with respect to each of the
         properties owned by it in an amount and on such terms as is reasonable
         and customary for businesses of this type.

                  (xxiii) The Company has continuously been organized and
         operated in conformity with the requirements for qualification as a
         real estate investment trust under the Internal Revenue Code of 1986,
         as amended (the "Code") for all taxable years commencing with its
         taxable year ended December 31, 1994. The Company has filed an election
         to be taxed as a real estate investment trust for all subsequent
         taxable years, and no such election has been terminated. The Company's
         proposed method of operation will permit it to continue to meet the
         requirements for taxation as a real estate investment trust under the
         Code.

                  (xxiv) Except as disclosed in the Prospectus, each entity
         identified in the Prospectus as a tenant of any property, or a
         subtenant thereof, has entered into a lease or a sublease, if
         applicable, for the possession of such property; except as disclosed in
         the Prospectus and to the knowledge of the Company and the Operating
         Partnership, each such lease is in full force and effect and neither
         the Company nor the Operating Partnership has notice of any defense to
         the obligations of the tenant thereunder or any claim asserted or
         threatened by any person or entity, the absence or unenforceability of
         which lease, or which defense or claim, if sustained, would have a
         material adverse effect on the conduct of the business, operations,
         financial condition or income of the Company, the Operating Partnership
         and the Subsidiaries, taken as a whole; and except as disclosed in the
         Prospectus, the lessor under each lease has complied with its
         obligations under such lease in all material respects and neither the
         Company nor the Operating Partnership has notice of any default by the
         tenant under such lease which, individually or in the aggregate with
         other such defaults as to which the Company or the Operating
         Partnership has been given notice, would have a material adverse effect
         on the conduct of the business, operations, financial condition or
         income of the Company, the Operating Partnership and the Subsidiaries,
         taken as a whole.

                  (xxv) Any certificate signed by any officer of the Company or
         by the Company as general partner of the Operating Partnership and
         delivered to you or to your counsel shall be


                                      -11-
   12
         deemed a representation and warranty by the Company or the
         Operating Partnership, as the case may be, to you as to the
         matters covered thereby.

                  (xxvi) A registration statement relating to the Common Shares
         has been declared effective by the Commission pursuant to the Exchange
         Act and the Common Shares are duly registered thereunder. The Shares
         have been approved for listing on the New York Stock Exchange, subject
         to notice of issuance or sale of the Shares, as the case may be.

         4. Additional Covenants. The Company covenants and agrees with you
that:

                  (a) The Company will (i) prepare a Prospectus Supplement
         setting forth the number of Shares covered thereby and such of their
         terms, if any, as are not otherwise specified in the Prospectus
         pursuant to which the Shares are being offered and sold, the name of
         the Underwriter and the number of Shares which the Underwriter has
         agreed to purchase, the price at which the Shares are to be purchased
         by the Underwriter from the Company and such other information as the
         Underwriter and the Company deem appropriate in connection with the
         offering of the Shares, and file the Prospectus in a form approved by
         you pursuant to Rule 424(b) under the Act no later than the
         Commission's close of business on the second business day following the
         date of the determination of the offering price of the Shares; (ii) not
         file (and the Operating Partnership will not so file) any amendment to
         the Registration Statement or supplement to the Prospectus, in either
         case, relating to the offering and sale of the Shares, of which you
         shall not previously have been advised and furnished with a copy or to
         which you shall have reasonably objected in writing or which is not in
         compliance with the Rules and Regulations; and (iii) promptly notify
         you after it shall have received notice of the time when any amendment
         to the Registration Statement relating to the offering and sale of the
         Shares becomes effective or when any supplement to the Prospectus
         relating to the offering and sale of the Shares has been filed.

                  (b) The Company or the Operating Partnership, as the case may
         be, will advise you promptly, after it shall receive notice or obtain
         knowledge, of any request of the Commission for amendment of the
         Registration Statement relating to the offering and sale of the Shares
         or for supplement to the Prospectus relating to the offering and sale
         of the Shares or for any additional information relating to the
         offering and sale of the Shares, or of the issuance by the Commission
         of any stop order suspending the effectiveness of the Registration
         Statement relating to the offering and sale of the Shares or the use of
         the Prospectus relating to the offering and sale of the Shares or of
         the institution or threatening of any proceedings for that purpose
         relating to the offering and sale of the Shares, and the Company and
         the


                                      -12-
   13
         Operating Partnership will use their best efforts to prevent the
         issuance of any such stop order preventing or suspending the use of the
         Prospectus in connection with the offering and sale of the Shares and
         to obtain as soon as possible the lifting thereof, if issued.

                  (c) The Company will cooperate with you and your counsel in
         endeavoring to qualify the Shares for sale under the securities laws of
         such jurisdictions as you may have designated and will make such
         applications, file such documents, and furnish such information as may
         be necessary for that purpose, provided the Company shall not be
         required to qualify as a foreign corporation or to file a general
         consent to service of process in any jurisdiction where it is not now
         so qualified or required to file such a consent or to subject itself to
         taxation as doing business in any jurisdiction where it is not now so
         taxed. The Company will, from time to time, file such statements,
         reports, and other documents, as are or may be required to continue
         such qualifications in effect for so long a period as you may
         reasonably request, subject to the foregoing provision.

                  (d) The Company will deliver to you, without charge, as many
         copies of the Prospectus (including all documents incorporated by
         reference therein), or as it thereafter may be amended or supplemented
         in connection with the offering and sale of the Shares, as you may from
         time to time reasonably request. The Company consents to the use of
         such Prospectus by you, both in connection with the offering or sale of
         the Shares and for such period of time thereafter as the Prospectus is
         required by law to be delivered, and for such other purposes as may be
         legally required in connection with the offering or sale of the Shares.
         The Company will deliver to you at or before the Closing Date two
         conformed copies of the Registration Statement and all amendments
         thereto, including all exhibits filed therewith or incorporated by
         reference therein and all documents incorporated by reference in the
         Prospectus and will deliver to you such number of copies of the
         Registration Statement, without exhibits, and of all amendments
         thereto, as you may reasonably request.

                  (e) If, during the period in which a prospectus is required by
         law to be delivered by an underwriter or dealer in connection with the
         offering and sale of the Shares, any event shall occur as a result of
         which, in the judgment of the Company or in your judgment or in the
         opinion of your counsel, it becomes necessary to amend or supplement
         the Prospectus in order to make the statements therein, in light of the
         circumstances existing at the time the Prospectus is delivered to a
         purchaser, not misleading, or, if it is necessary at any time to amend
         or supplement the Prospectus in connection with the offering and sale
         of the Shares to comply with any law, the Company promptly will prepare
         and file with the Commission an appropriate amendment to the
         Registration Statement or


                                      -13-
   14
         supplement to the Prospectus so that the Prospectus as so amended or
         supplemented will not, in the light of the circumstances when it is so
         delivered, be misleading, or so that the Prospectus will comply with
         law.

                  (f) The Company will make generally available to its
         shareholders and will file as an exhibit in a report pursuant to the
         Exchange Act, as soon as it is practicable to do so, but in any event
         not later than 15 months after the effective date of the Registration
         Statement, an earnings statement in reasonable detail, covering a
         period of at least 12 consecutive months beginning after the effective
         date of the Registration Statement, which earnings statement shall
         satisfy the requirements of Section 11(a) of the Act and Rule 158 of
         the Rules and Regulations and will advise you in writing when such
         statement has been so made available.

                  (g) The Company will, for a period of five years from the
         Closing Date, deliver to you at your principal executive offices a
         reasonable number of copies of annual reports, quarterly reports,
         current reports and copies of all other documents, reports and
         information furnished by the Company to its shareholders or filed with
         any securities exchange pursuant to the requirements of such exchange
         or with the Commission pursuant to the Act or the Exchange Act. The
         Company will deliver to you similar reports with respect to any
         significant subsidiaries, as that term is defined in the Rules and
         Regulations, which are not consolidated in the Company financial
         statements. Any report, document or other information required to be
         furnished under this paragraph (g) shall be furnished as soon as
         practicable after such report, document or information becomes
         available.

                  (h) The Company will apply the proceeds from the sale of the
         Shares as set forth in the description under "Use of Proceeds" in the
         Prospectus, which description complies in all respects with the
         requirements of Item 504 of Regulation S-K of the Commission.

                  (i) The Company will supply you with copies of all
         correspondence to and from, and all documents issued to and by, the
         Commission in connection with the registration of the Shares under the
         Act.

                  (j) Prior to the Closing Date, the Company will furnish to
         you, as soon as they have been prepared, copies of any unaudited
         interim consolidated financial statements of the Company and its
         subsidiaries for any periods subsequent to the periods covered by the
         financial statements included in the Registration Statement and the
         Prospectus.

                  (k) Prior to the Closing Date, the Company will not issue any
         press releases or other communications directly or indirectly and will
         hold no press conference, with respect to


                                      -14-
   15
         the Company or any of its subsidiaries, the financial condition,
         results of operations, business, properties, assets or liabilities of
         the Company or any of its subsidiaries, or the offering of the Shares,
         without your prior written consent.

                  (l) The Company will use its best efforts to obtain approval
         for, and maintain the listing of the Shares on, the New York Stock
         Exchange.

                  (m) The Company and the Operating Partnership will maintain
         and keep accurate books and records reflecting their assets and
         maintain internal accounting controls which provide reasonable
         assurance that (1) transactions are executed in accordance with
         management's authorization, (2) transactions are recorded as necessary
         to permit the preparation of the Company's consolidated financial
         statements and to maintain accountability for the assets of the
         Company, the Operating Partnership and the Subsidiaries, (3) access to
         the assets of the Company, the Operating Partnership and the
         Subsidiaries is permitted only in accordance with management's
         authorization, and (4) the recorded accounts of the assets of the
         Company, the Operating Partnership and the Subsidiaries are compared
         with existing assets at reasonable intervals.

                  (n) During any period in which a prospectus is required by law
         to be delivered by an Underwriter or dealer in connection with the
         offering and sale of the Shares, the Company and the Operating
         Partnership will promptly file all documents required to be filed with
         the Commission pursuant to Sections 13, 14 or 15(d) of the Exchange
         Act.

                  (o) The Company will use its best efforts to continue to meet
         the requirements to qualify as a "real estate investment trust" under
         the Code.

         5. Conditions of Underwriter's Obligation. Your obligations, as
Underwriter to purchase and pay for the Shares, as provided herein, shall be
subject to the accuracy in all material respects, as of the dare hereof and as
of the Closing Date, of the representations and warranties of the Company and
the Operating Partnership contained herein, to the performance in all material
respects by the Company of its covenants and obligations hereunder, and to the
following additional conditions:

                  (a) All filings in connection with the offering and sale of
         the Shares required by Rule 424 of the Rules and Regulations shall have
         been made. No stop order suspending the effectiveness of the
         Registration Statement, as amended from time to time, shall have been
         issued and no proceeding for that purpose shall have been initiated or,
         to your knowledge or the knowledge of the Company or the Operating
         Partnership, threatened or contemplated by the Commission, and any
         request of the Commission for additional information (to


                                      -15-
   16
         be included in the Registration Statement or the Prospectus or
         otherwise in connection with the offering and sale of the Shares) shall
         have been complied with to your reasonable satisfaction.

                  (b) You shall not have disclosed in writing to the Company, on
         or prior to the Closing Date, that the Registration Statement or
         Prospectus or any amendment or supplement thereto contains an untrue
         statement of fact which, in the opinion of your counsel, is material,
         or omits to state a fact which, in the opinion of such counsel, is
         material and is required to be stated therein or is necessary to make
         the statements therein, in light of the circumstances under which they
         were made, not misleading.

                  (c) On the Closing Date, you shall have received the opinions
         of Wolf, Block, Schorr and Solis-Cohen LLP and Weinberg & Green, LLC,
         counsel for the Company, addressed to you and dated the Closing Date,
         as to the matters set forth in Schedule I attached hereto.

                  (d) You shall have received on the Closing Date, from Chapman
         and Cutler, your counsel, such opinion or opinions, dated the Closing
         Date with respect to the organization of the Company, the validity of
         the issuance of the Shares, the Registration Statement, the Prospectus
         and other related matters as you may reasonably require; the Company
         shall have furnished to such counsel such documents as they reasonably
         request for the purpose of enabling them to pass on such matters.

                  (e) You shall have received at or prior to the Closing Date
         from Chapman and Cutler a memorandum or memoranda, in form and
         substance satisfactory to you, with respect to the qualification for
         offering and sale by you of the Shares under state securities or Blue
         Sky laws of such jurisdictions as you may have designated to the
         Company.

                  (f) On the date of this Agreement and on the Closing Date, you
         shall have received from Ernst & Young, LLP, a letter or letters, dated
         the date of this Agreement and the Closing Date, respectively, in form
         and substance satisfactory to you, confirming that they are independent
         public accountants with respect to the Company within the meaning of
         the Act and the published Rules and Regulations, and stating to the
         effect set forth in Schedule II hereto.

                  (g) Except as contemplated in the Prospectus, (i) neither the
         Company, the Operating Partnership nor any of the Subsidiaries shall
         have sustained since the date of the latest audited financial
         statements included or incorporated by reference in the Prospectus any
         loss or interference with its business from fire, explosion, flood or
         other calamity, whether or not covered by insurance, or from any labor
         dispute


                                      -16-
   17
         or court or governmental action, order or decree; and (ii) subsequent
         to the respective dates as of which information is given in the
         Registration Statement and the Prospectus, neither the Company, the
         Operating Partnership nor any of the Subsidiaries shall have incurred
         any liability or obligation, direct or contingent, or entered into
         transactions, and there shall not have been any change in the Common
         Shares, the Units or long-term debt of the Company, the Operating
         Partnership and the Subsidiaries or any change in the condition
         (financial or other), net worth, business, affairs, management,
         prospects or results of operations of the Company, the Operating
         Partnership or the Subsidiaries, the effect of which, in any such case
         described in clause (i) or (ii), is in your reasonable judgment so
         material and adverse as to make it impracticable or inadvisable to
         proceed with the offering or the delivery of the Shares being delivered
         on the Closing Date on the terms and in the manner contemplated in the
         Prospectus.

                  (h) There shall not have occurred any of the following: (i) a
         suspension or material limitation in trading in securities generally on
         the New York Stock Exchange or the American Stock Exchange or the
         establishing on such exchanges by the Commission or by such exchanges
         of minimum or maximum prices which are not in force and effect on the
         date hereof; (ii) a general moratorium on commercial banking activities
         declared by either federal or state authorities; (iii) the outbreak or
         escalation of hostilities involving the United States or the
         declaration by the United States of a national emergency or war, if the
         effect of any such event specified in this clause (iii) in your
         judgment makes it impracticable or inadvisable to proceed with the
         offering or the delivery of the Shares in the manner contemplated in
         the Prospectus; (iv) any calamity or crisis, change in national,
         international or world affairs, act of God, change in the international
         or domestic markets, or change in the existing financial, political or
         economic conditions in the United States or elsewhere, if the effect of
         any such event specified in this clause (iv) makes it impracticable or
         inadvisable to proceed with the offering or the delivery of the Shares
         in the manner contemplated in the Prospectus; or (v) the enactment,
         publication, decree, or other promulgation of any federal or state
         statute, regulation, rule, or order of any court or other governmental
         authority, or the taking of any action by any federal, state or local
         government or agency in respect of fiscal or monetary affairs, if the
         effect of any such event specified in this clause (v) in your judgment
         makes it impracticable or inadvisable to proceed with the offering or
         the delivery of the Shares in the manner contemplated in the
         Prospectus.

                  (i) You shall have received certificates, dated the Closing
         Date and signed by the Chief Executive Officer or the President and the
         Chief Financial Officer of the Company


                                      -17-
   18
         stating that (i) they have examined the Registration Statement and the
         Prospectus as amended or supplemented and all documents incorporated by
         reference therein and nothing has come to their attention that would
         lead them to believe that (i) either the Registration Statement or the
         Prospectus, or any amendment or supplement thereto, or any documents
         incorporated by reference therein, as of their respective effective,
         issue or filing dates, as the case may be, or (ii) the Prospectus, as
         amended or supplemented, and when read together with the documents
         incorporated by reference therein, as of the Closing Date, contained or
         contains, as of such date, any untrue statement of a material fact, or
         omits to state a material fact required to be stated therein or
         necessary in order to make the statements therein, in light of the
         circumstances under which they were made, not misleading, and, that
         (ii) all representations and warranties made herein by the Company and
         the Operating Partnership are true and correct in all material respects
         at the Closing Date, with the same effect as if made on and as of the
         Closing Date, and all agreements herein to be performed by the Company
         on or prior to the Closing Date have been duly performed in all
         material respects.

                  (j) The Company and the Operating Partnership shall not have
         failed, refused, or been unable, at or prior to the Closing Date to
         have performed in all material respects any agreement on their part to
         be performed or any of the conditions herein contained and required to
         be performed or satisfied by them at or prior to the Closing Date.

                  (k) The Company and the Operating Partnership shall have
         furnished to you at the Closing Date such other certificates as you may
         have reasonably requested as to the accuracy, on and as of the Closing
         Date, of the representations and warranties of the Company and the
         Operating Partnership herein and as to the performance by the Company
         and the Operating Partnership of their obligations hereunder. (l) The
         Shares shall have been approved for trading on the New York Stock
         Exchange upon official notice of issuance thereof.

         All such opinions, certificates, letters and documents will be in
compliance with the provisions hereof only if they are reasonably satisfactory
to you and to Chapman and Cutler, your counsel. The Company and the Operating
Partnership will furnish you with such conformed copies of such opinions,
certificates, letters and documents as you may request.

         If any of the conditions specified above in this Section 5 shall not
have been satisfied at or prior to the Closing Date or waived by you in writing,
this Agreement may be terminated by you on notice to the Company.

         6. Indemnification. (a) The Company and the Operating


                                      -18-
   19
Partnership will indemnify and hold harmless you and each person, if any, who
controls you within the meaning of the Act, against any losses, claims, damages
or liabilities, joint or several, to which you or such controlling person may
become subject, under the Act or otherwise, insofar as such losses, claims,
damages or liabilities (or actions in respect thereof) arise out of or are based
upon an untrue statement or alleged untrue statement of a material fact
contained in the Registration Statement, any Preliminary Prospectus, the
Prospectus, or any amendment or supplement thereto, or in any blue sky
application or other document executed by the Company or the Operating
Partnership or based on any information furnished in writing by the Company or
the Operating Partnership, filed in any jurisdiction in order to qualify any or
all of the Shares under the securities laws thereof ("Blue Sky Application"), or
arise out of or are based upon the omission or alleged omission to state therein
a material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading; and will reimburse you and each such controlling person for any
legal or other expenses reasonably incurred by you or such controlling person in
connection with investigating or defending any such loss, claim, damage,
liability or action; provided, however, that the Company and the Operating
Partnership shall not be liable in any such case to the extent that any such
loss, claim, damage or liability arises out of or is based upon an untrue
statement or alleged untrue statement or omission or alleged omission made in
the Registration Statement, such Preliminary Prospectus or the Prospectus, or
such amendment or supplement, or any Blue Sky Application in reliance upon and
in conformity with written information furnished to the Company by you,
specifically for use in the preparation thereof; and provided, further, that if
any Preliminary Prospectus or the Prospectus contained any alleged untrue
statement or allegedly omitted to state therein a material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstance under which they were made, not misleading and such statement or
omission shall have been corrected in a revised Preliminary Prospectus or in the
Prospectus or in an amended or supplemented Prospectus, the Company and the
Operating Partnership shall not be liable to you or controlling persons under
this subsection (a) with respect to such alleged untrue statement or alleged
omission to the extent that any such loss, claim, damage or liability of such
person results from the fact that you sold Shares to a person to whom there was
not sent or given, at or prior to the written confirmation of such sale, such
revised Preliminary Prospectus or Prospectus or amended or supplemented
Prospectus. In addition to its other obligations under this Section 6(a), the
Company and the Operating Partnership agree that, as an interim measure during
the pendency of any claim, action, investigation, inquiry or other proceeding
arising out of or based upon any statement or omission, or any alleged statement
or omission, described in this Section 6(a), it will reimburse you on a monthly
basis for all reasonable legal and other expenses incurred in connection with
investigating or defending any such claim, action, investigation, inquiry or
other proceeding,


                                      -19-
   20
notwithstanding the absence of a judicial determination as to the propriety and
enforceability of the obligation of the Company and the Operating Partnership to
reimburse you for such expenses and the possibility that such payments might
later be held to have been improper by a court of competent jurisdiction. This
indemnity agreement shall be in addition to any liabilities which the Company
and the Operating Partnership may otherwise have.

         (b) You will indemnify and hold harmless the Company and the Operating
Partnership, each of the Company's trustees, each of the Company's officers who
have signed the Registration Statement and each person, if any, who controls the
Company or the Operating Partnership within the meaning of the Act, against any
losses, claims, damages or liabilities, joint or several, to which the Company,
the Operating Partnership or any such trustee, officer or controlling person may
become subject, under the Act or otherwise, insofar as such losses, claims,
damages or liabilities (or actions in respect thereof) arise out of or are based
upon any untrue statement or alleged untrue statement of any material fact
contained in the Registration Statement, any Preliminary Prospectus, the
Prospectus, any amendment or supplement thereto, or any Blue Sky Application or
arise out of or are based upon the omission or the alleged omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein, in light of the circumstances under which they were made,
not misleading, in each case to the extent, but only to the extent, that such
untrue statement or alleged untrue statement or omission or alleged omission was
made in the Registration Statement, such Preliminary Prospectus or the
Prospectus, such amendment or supplement, or any Blue Sky Application in
reliance upon and in conformity with written information furnished to the
Company by you specifically for use in the preparation thereof; and will
reimburse any legal or other expenses reasonably incurred by the Company, the
Operating Partnership or any such trustee, officer or controlling person in
connection with investigating or defending any such loss, claim, damage,
liability or action. In addition to your other obligations under this Section
6(b), you agree that, as an interim measure during the pendency of any claim,
action, investigation, inquiry or other proceeding arising out of or based upon
any statement or omission, or any alleged statement or omission, described in
this Section 6(b), you will reimburse the Company and the Operating Partnership
on a monthly basis for all reasonable legal and other expenses incurred in
connection with investigating or defending any such claim, action,
investigation, inquiry or other proceeding, notwithstanding the absence of a
judicial determination as to the propriety and enforceability of your obligation
to reimburse the Company and the Operating Partnership for such expenses and the
possibility that such payments might later be held to have been improper by a
court of competent jurisdiction. This indemnity agreement shall be in addition
to any liabilities which you may otherwise have.

         (c) Any party which proposes to assert the right to be indemnified
under this Section 6 shall, within ten days after


                                      -20-
   21
receipt of notice of commencement of any action, suit or proceeding against such
party in respect of which a claim is to be made against an indemnifying party
under this Section 6, notify each such indemnifying party of the commencement of
such action, suit or proceeding, enclosing a copy of all papers served, but the
omission so to notify such indemnifying party of any such action, suit or
proceeding shall not relieve such indemnifying party from any liability which it
may have to any indemnified party under this Section 6 unless such indemnifying
party has been materially prejudiced by such omission and such omission shall
not relieve such indemnifying party from any liability which it may have to any
indemnified party otherwise than under this Section 6. In case any such action,
suit or proceeding shall be brought against any indemnified party and it shall
notify the indemnifying party of the commencement thereof, the indemnifying
party shall be entitled to participate in, and, to the extent that it shall
wish, jointly with any other indemnifying party similarly notified, to assume
the defense thereof, with counsel reasonably satisfactory to such indemnified
party, and after notice from the indemnifying party to such indemnified party of
its election so to assume the defense thereof, the indemnifying party shall not
be liable to such indemnified party for any legal or other expenses, other than
reasonable costs of investigation, subsequently incurred by such indemnified
party in connection with the defense thereof. The indemnified party shall have
the right to employ its own counsel in any such action, but the fees and
expenses of such counsel shall be at the expense of such indemnified party
unless (i) the employment of counsel by such indemnified party at the expense of
the indemnifying party has been authorized by the indemnifying party, (ii) the
indemnified party shall have been advised by such counsel in a written opinion
that there may be a conflict of interest between the indemnifying party and the
indemnified party in the conduct of the defense, or certain aspects of the
defense, of such action (in which case the indemnifying party shall not have the
right to direct the defense of such action with respect to those matters or
aspects of the defense on which a conflict exists or may exist on behalf of the
indemnified party) (provided, however, that the indemnifying party shall not be
required to pay the fees and expenses of more than one counsel for all of the
indemnified parties entitled to separate counsel pursuant to this clause (ii))or
(iii) the indemnifying party shall not in fact have employed counsel to assume
the defense of such action, in any of which events such fees and expenses to the
extent reasonable and applicable shall be borne by the indemnifying party. An
indemnifying party shall not be liable for any settlement of any action or claim
effected without its consent. Each indemnified party, as a condition of such
indemnity, shall cooperate in good faith with the indemnifying party in the
defense of any such action or claim.

         (d) If the indemnification provided for in this Section 6 is for any
reason, other than pursuant to the terms thereof, judicially determined (by the
entry of a final judgment or decree by a court of competent jurisdiction and the
expiration of time to


                                      -21-
   22
appeal or the denial of the last right to appeal) to be unavailable to an
indemnified party under subsection (a) or (b) above in respect of any losses,
claims, damages or liabilities (or actions in respect thereof) referred to
therein, then each indemnifying party shall, in lieu of indemnifying such
indemnified party, contribute to the amount paid or payable by such indemnified
party as a result of such losses, claims, damages or liabilities (or actions in
respect thereof) in such proportion as is appropriate to reflect the relative
benefits received by the Company and the Operating Partnership, on the one hand,
and you, on the other hand, from the offering of the Shares. If, however, the
allocation provided by the immediately preceding sentence is not permitted by
applicable law, then each indemnifying party shall contribute to such amount
paid or payable by such indemnified party in such proportion as is appropriate
to reflect not only such relative benefits but also the relative fault, as
applicable, of the Company and the Operating Partnership, on the one hand, and
you, on the other hand, in connection with the statements or omissions which
resulted in such losses, claims, damages or liabilities (or actions in respect
thereof), as well as other relevant equitable considerations. The relative
benefits received by, as applicable, the Company and the Operating Partnership
taken together and you shall be deemed to be in the same proportion as the total
net proceeds from the offering (before deducting expenses) received by the
Company bear to the total underwriting discounts and commissions received by
you, in each case as set forth in the table on the cover page of the Prospectus.
The relative fault shall be determined by reference to, among other things,
whether the untrue statement of a material fact or the omission or alleged
omission to state a material fact relates to information supplied by the Company
or the Operating Partnership, on the one hand, or you, on the other hand, and
the parties' relative intent, knowledge, access to information and opportunity
to correct or prevent such statement or omission. The Company, the Operating
Partnership and you agree that it would not be just and equitable if
contributions pursuant to this subsection (d) were determined by pro rata
allocation or by any other method of allocation which does not take account of
the equitable considerations referred to above in this subsection (d). The
amount paid or payable by an indemnified party as a result of the losses,
claims, damages or liabilities (or actions in respect thereof) referred to above
in this subsection (d) shall be deemed to include any legal or other expenses
reasonably incurred by such indemnified party in connection with investigating
or defending any such action or claim. Notwithstanding the provisions of this
subsection (d), you shall not be required to contribute any amount in excess of
the amount by which the total price at which the Shares underwritten by you and
sold in the offering were offered exceeds the amount of any damages which you
have otherwise paid or become liable to pay by reason of any 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.


                                      -22-
   23
         7. Representations and Agreements to Survive Delivery. All
representations, warranties, and agreements of the Company, the Operating
Partnership and you contained herein or in certificates delivered pursuant
hereto, including your agreements contained in Section 6 hereof, shall remain
operative and in full force and effect regardless of any termination or

termination shall be without liability of any party to any other party except as
provided in Sections 6 and 9 hereof.

         If you terminate this Agreement as provided in Sections 8(b), you shall
notify the Company by telephone or telegram, confirmed by letter.

         9. Cost and Expenses. The Company will bear and pay the costs and
expenses incident to the registration of the Shares and public offering thereof,
including, without limitation, (a) the fees and expenses of the Company's
accountants and the fees and expenses of counsel for the Company, (b) the
preparation, printing, filing, delivery and shipping of the Registration
Statement, each Preliminary Prospectus, the Prospectus, and any amendments or
supplements thereto (c) the furnishing of copies of such documents to you, (d)
the registration or qualification of the Shares for offering and sale under the
securities laws of the various states, including the reasonable fees and
disbursements of your counsel relating to such registration or qualification,
(e) the fees payable to the NASD (if any) and the Commission in connection with
their review of the proposed offering of the Shares, (f) all printing and
engraving costs related to preparation of the certificates for the Shares,
including transfer agent and registrar fees, (g) all initial transfer taxes, if
any, (h) all fees and expenses relating to the authorization of the Shares for
trading on the New York Stock Exchange, (i) all travel expenses, including air
fare and accommodation expenses, of representatives of the Company in connection
with the offering of the Shares and (j) all of the other costs and expenses
incident to the performance by the Company of the registration and offering of
the Shares; provided, however, that you will bear and pay the fees and expenses
of your counsel (other than fees and disbursements relating to the registration
or qualification of the Shares for offering and sale under the securities laws
of the various states), your out-of-pocket expenses, and any advertising costs
and expenses incurred by you incident to the public offering of the Shares.

   24
         If this Agreement is terminated by you in accordance with the

out-of-pocket expenses, including the reasonable fees and disbursements of your
counsel.
