     of business, except where the failure to so qualify or register would not

     proceeding in equity or at law). This Agreement, the Deposit Agreement, the
     Operating Partnership Agreement and the Material Agreements are sometimes
     herein collectively called the "Company Documents."

          (q) The execution and delivery of this Agreement and the Deposit
     Agreement, the issuance of the Preferred Shares, the issuance and sale of
     the Shares, the performance of the obligations set forth herein or therein
     and the consummation of the transactions contemplated hereby and thereby or
     in the Prospectus by the Transaction Entities will not conflict with or
     constitute a material breach or violation by such parties of, or default
     under or result in the creation or imposition of any lien, charge or
     encumbrance upon any Facility, or any other property or asset of a
     Transaction Entity under or pursuant to, (i) any of the other Company
     Documents or (ii) any contract, indenture, mortgage, loan agreement, note,
     lease, joint venture or partnership agreement or other instrument or
     agreement to which any Transaction Entity is a party or by which they, any
     of them, any of their respective properties or other assets or any Facility
     may be bound or subject, nor will such action conflict with or constitute a
     breach or violation by the Transaction Entities of, or default under, (X)
     the articles of incorporation, by-laws, certificate of limited partnership,
     partnership agreement or other governing documents, as the case may be, of
     any Transaction Entity or (Y) any applicable law, rule, order,
     administrative regulation or administrative or court decree.

          (r) (i)  No labor dispute with employees of either of the Primary
     Entities exists or is imminent, and (ii) no Primary Entity is aware of any
     existing or imminent labor disturbance by the employees of any of the
     Transaction Entities' principal suppliers, manufacturers or contractors,
     which, in the case of either (i) or (ii), might be expected to result in
     any Material Adverse Change.  No collective bargaining agreement exists
     with the employees of any of the Primary Entities, and to the best
     knowledge of either of the Primary Entities, no such agreement is imminent.

          (s) There is no action, suit or proceeding before or by any court or
     governmental agency or body, domestic or foreign, now pending, or, to the
     knowledge of  the Primary Entities, after due inquiry, threatened against
     or affecting any Transaction Entity, Facility or, to the knowledge of the
     Company, any officer or director of the Company, which is required to be
     disclosed in the Registration Statement or the

                                      -9-


     Prospectus (other than as disclosed therein), or that, if determined
     adversely to any Transaction Entity, Facility or such officer or director,
     will or could reasonably be expected to result in a Material Adverse Change
     or to prevent consummation of the transaction contemplated hereby. There
     are no pending legal or governmental proceedings to which any Transaction
     Entity is a party or of which they or any of their respective properties or
     assets or any Facility is the subject, including ordinary routine
     litigation incidental to the business, that, considered in the aggregate,
     could reasonably be expected to result in a Material Adverse Change. There
     are no contracts or documents of any Transaction Entity which are required
     to be filed as exhibits to the Registration Statement by the Act or which
     were required to be filed as exhibits to any of the Incorporated Documents
     by the Exchange Act, which have not been so filed, or which are required to
     be incorporated by reference into the Prospectus by the Act or the Exchange
     Act which have not been so incorporated.

     to be, 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"), and its proposed method of operation
     will enable it to continue to meet the requirements for taxation as a real
     estate investment trust under the Code.

          (u) Each of the Transaction Entities has filed all federal, state,
     local and foreign income tax returns which have been required to be filed
     and has paid all taxes required to be paid and any other assessment, fine
     or penalty levied against it, to the extent that any of the foregoing is
     due and payable, except, in all cases, for any such tax assessment, fine or
     penalty that is being contested in good faith and except in any case in
     which the failure to so pay would not result in a Material Adverse Change.

          (v) At all times since its formation, the Operating Partnership has
     been, and upon the sale of the Shares will continue to be, classified as a
     partnership for Federal income tax purposes.

     the business proposed to be operated by the Transaction Entities.

          (y) No authorization, approval, consent or order of any court or
     governmental authority or agency or other entity or person is necessary in
     connection with the offering, the execution and delivery of this Agreement
     or the Deposit Agreement, the issuance of the Preferred Shares or the
     issuance or sale of the Shares hereunder, except such as may

                                      -10-


     be required under the Act or state securities, real estate syndication or
     blue sky laws, or the listing requirements of the American Stock Exchange
     or such as have been received.

          (z)  Each of the Transaction Entities possesses, and at the Closing
     Date will possess, such certificates, authorizations or permits issued by
     the appropriate local, state, federal or foreign regulatory agencies or
     bodies necessary to conduct the business now operated by it, or proposed to
     be conducted by it, except for such certificates, authorizations and
     permits, the failure to obtain, maintain or possess which by any of the
     Transaction Entities would not result, singly or in the aggregate, in a
     Material Adverse Change, and none of the Transaction Entities has received
     any notice of proceedings relating to the revocation or modification of any
     such certificate, authority or permit which, singly or in the aggregate, if
     the subject of an unfavorable decision, ruling or finding, would result in
     a Material Adverse Change.

          (aa) Except as disclosed in the Prospectus, there are no persons with
     registration or other similar rights to have any securities registered
     pursuant to the Registration Statement that have not been waived in

     the American Stock Exchange and the Shares will be listed on the American
     Stock Exchange, subject to official notice of issuance.

          (cc) The Company has taken no action designed to, or likely to have
     the effect of, terminating the registration of the Common Stock or the
     Series A Stock or the Series D Stock under the Exchange Act or delisting
     the Common Stock or the Series A Stock or the Series D Stock from the
     American Stock Exchange, nor has the Company received any notification that

     any such registration or listing.

          (dd) The Company has not distributed and will not distribute prior to
     the later of (i) the Closing Date or (ii) completion of the distribution of
     the Shares, any offering material in connection with the offering and sale
     of the Shares other than any Preliminary Prospectuses, the Prospectus, the
     Registration Statement and other materials, if any, permitted by the Act.

          (ee) Neither the Company nor any of its subsidiaries has at any time
     during the last five (5) years (i) made any unlawful contribution to any
     candidate for foreign office or failed to disclose fully any contribution
     in violation of law, or (ii) made any payment to any federal or state
     governmental officer or official, or other person charged with similar
     public or quasi-public duties, other than payments required or permitted by
     the laws of the United States or any jurisdiction thereof.

                                      -11-


          (ff) The Company has not taken and will not take, directly or
     indirectly, any action designed to or that might reasonably be expected to
     cause or result in stabilization or manipulation of the price of the Common
     Stock or the Series A Stock or the Series D Stock to facilitate the sale or
     resale of the Shares in violation of the Act.

          (gg) (i) At the Closing Date, the Company, the Operating Partnership
     or one of the other Transaction Entities will have good and marketable
     title (or, with respect to any Facilities located in Texas, good and
     indefeasible fee simple title, or such substantially equivalent quality of
     title as provided by the applicable title insurance policy) to each of the
     Facilities and all other items of real property (and improvements therein),
     in each case free and clear of all liens, encumbrances, claims, security
     interests and defects, other than those (A) referred to in the Registration
     Statement or described in any document incorporated into the Registration
     Statement by reference or (B) which are not material in amount; (ii) all
     liens, charges, encumbrances, claims or restrictions on or affecting any of

     otherwise described in the Prospectus, neither Primary Entity is, and, to
     the best knowledge of the Primary Entities, no Transaction Entity is, in

     case may be) relating to the Facilities, or (B) any of the mortgage or
     other security documents or other agreements encumbering or otherwise
     recorded against the Facilities, and no Primary Entity knows, after due
     inquiry, of any event which, but for the passage of time or the giving of
     notice, or both, would constitute a default under any of such documents or
     agreements; (iv) each of the Facilities complies with all applicable codes,
     laws and regulations (including, without limitation, building and zoning
     codes, laws and regulations and laws relating to access to the Facilities);
     and (v) no Primary Entity has knowledge of, after due inquiry, any pending
     or threatened condemnation proceeding, zoning change or other proceeding or
     action that will in any manner affect the size of, use of, improvements on,
     construction on or access to the Facilities, except in each case for such
     matters as could not, individually or in the aggregate, result in a
     Material Adverse Change.

          (hh) Each of the Facilities has property, title, casualty and
     liability insurance in favor of either the Company, the Operating
     Partnership, or one of the Transaction Entities with respect to the
     Facilities by insurers of recognized financial responsibility against such
     losses and risks and in such amounts as are prudent and customary in the
     businesses in which they are engaged, provided, that with respect to
     certain Facilities, title insurance is held by Public Storage, Inc., a
     California corporation ("PSI"), or an affiliate of PSI under policies the
     benefits of which have been assigned to the Company or the Operating
     Partnership pursuant to a binding agreement, or PSI has indemnified the
     Company, the Operating Partnership or the respective Transaction Entity
     against material defects in title to the Facilities pursuant to a binding
     agreement; and none of the Company, the Operating Partnership, or the other
     Transaction Entities has any reason to believe that they will not be able
     to renew their existing insurance coverage as and when such coverage
     expires or to obtain similar coverage from similar insurers as may be
     necessary to continue their businesses at a cost that would not result in a
     Material Adverse Change, except as described in or contemplated by the
     Registration Statement and the Prospectus.

                                      -12-

     and no condition exists on, in or under any Facility or Land that could

     Environmental Law or give rise to the imposition of any Lien (as defined
     below) under any Environmental Law; (iii) none of the Transaction Entities

     dealer, file any amendment or supplement to the Registration Statement
     (including any filing under Rule 462(b) under the Act) or the Prospectus,
     unless a copy thereof shall first have been submitted to the
     Representatives within a reasonable period of time prior to the filing
     thereof and the Representatives shall not have objected thereto in good
     faith.

          (b) The Company will notify the Representatives promptly, and will
     confirm such advice in writing, (1) of the receipt of any comments from or
     any request by the Commission for amendments or supplements to the
     Registration Statement or the Prospectus or for additional information, (2)
     of the issuance by the Commission of any stop order suspending the
     effectiveness of the Registration Statement or the initiation of any
     proceedings for that purpose or the threat thereof, (3) of the happening of
     any event during the period mentioned in the second sentence of Section
     5(e) that in the judgment of the Company makes any statement made in the
     Registration Statement or the Prospectus untrue or that requires the making
     of any changes in the Registration Statement or the Prospectus in order to
     make the statements therein, in light of the circumstances in which they
     are made, not misleading, and (4) of receipt by the Company or any
     representative or attorney of the Company of any other communication from

     statement therein, in the light of the circumstances under which it was
     made, not misleading, or if it is necessary to supplement or amend the

     hereof, the Company will forthwith prepare and duly file with the
     Commission an appropriate supplement or amendment thereto, and will deliver

                         --------
     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 general
     service of process in any jurisdiction where it is not now so subject.

          (g) During the period of five years commencing on the date hereof, the
     Company will furnish to each of the Representatives and each other
     Underwriter who may so request copies of such financial statements and
     other periodic and special reports as the Company may from time to time
     distribute generally to the holders of any class of its capital stock, and
     will furnish to each of the Representatives and each other Underwriter who
     may so request a copy of each annual or other report it shall be required
     to file with the Commission.

          (h) The Company will make generally available to holders of its
     securities as soon as may be practicable but in no event later than the
     last day of the fifteenth full calendar month following the calendar
     quarter in which the Effective Date falls, a consolidated earnings
     statement (which need not be audited but shall be in reasonable detail),
     with respect to the Primary Entities, for a period of 12 months commencing
     after the Effective Date, and satisfying the provisions of Section 11(a) of
     the Act (including Rule 158 thereunder) and will file such earnings
     statement as an exhibit to the next periodic report required by Section 13
     or 15(d) of the Exchange Act covering the period when the earnings
     statement is released.

          (i) If this Agreement shall terminate or shall be terminated after
     execution pursuant to any provisions hereof (otherwise than pursuant to the
     second paragraph of Section 9 hereof or by notice given by you terminating
     this Agreement pursuant to Section 9 or Section 10 hereof) or if this
     Agreement shall be terminated by the Underwriters 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 the
     Representatives for all out-of-pocket expenses (including fees and expenses
     of counsel for the Underwriters) reasonably incurred by you in connection
     herewith.

                                      -16-


          (j) The Company will not at any time, directly or indirectly, take any
     action intended, or which might reasonably be expected, to cause or result
     in, or which will constitute, stabilization of the price of the Shares to
     facilitate the sale or resale of any of the Shares in violation of the Act.

          (k) The Company will apply the net proceeds from the offering and sale
     of the Shares in the manner set forth in the Prospectus under "Use of
     Proceeds."

          (l) The Company will use its best efforts to have the Shares listed,
     subject to notice of issuance, on the American Stock Exchange.

6.   Conditions of Underwriters' Obligations.  The several obligations of the
     ---------------------------------------
Underwriters to purchase the Shares hereunder are subject to the following
conditions:

          (a) All of the representations and warranties of the Company contained
     in this Agreement shall be true and correct on the Closing Date with the
     same force and effect as if made on and as of the Closing Date.

          (b) The Registration Statement (including any post-effective amendment
     thereto) shall have become effective not later than 5:00 P.M. (and, in the
     case of a Registration Statement filed under Rule 462(b) of the Act, not
     later than 10:00 p.m.), New York City time, on the date of this Agreement,
     or at such later date and time as shall be consented to in writing by the
     Representatives, and all filings, if any, required by Rules 424 and 430A
     under the Act shall have been timely made; and at the Closing Date no stop
     order suspending the effectiveness of the Registration Statement shall have
     been issued and no proceedings for that purpose shall have been instituted
     or, to the knowledge of the Company or any Underwriter, contemplated 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 the satisfaction of the
     Representatives.

          (c) 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, properties, net worth, or results of operations of the
     Transaction Entities not contemplated by the Prospectus, which in your
     opinion, as Representatives of the several Underwriters, 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 director
     of the Company which makes any statement made in the Prospectus untrue in
     any material respect or which, in the opinion of the Company and its
     counsel or the Underwriters 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 not misleading, if amending or
     supplementing the Prospectus to reflect such event or development would, in
     your opinion, as Representatives of the several Underwriters, adversely
     affect the market for the Shares.  On the Closing Date, the Underwriters
     shall have received a certificate dated the Closing Date, signed by each of
     the President and the

                                      -17-


     Chief Financial Officer of the Company confirming the matters set forth in
     Sections 6(a), (b) and (c).

          (d) The Underwriters shall have received an opinion, dated the Closing
     Date and satisfactory in form and substance to counsel for the
     Underwriters, from David Goldberg, counsel for the Company, to the effect
     that:

               (i)    Each of the Company and the Operating Partnership has been
          duly organized and is validly existing (in the case of the Company, as
          a corporation) in good standing under the laws of the jurisdiction in
          which it is organized, with full power and authority to own or lease
          and occupy its properties and conduct its business as described in the
          Prospectus, and is duly qualified to do business, and is in good
          standing, in each jurisdiction which requires such qualification,
          except where the failure to so qualify would not, individually or in
          the aggregate, have a Material Adverse Change;

               (ii)   All of the Company's ownership interest in the Operating
          Partnership is owned free and clear of any perfected security interest
          and, to my knowledge, after due inquiry, any other security interests,
          claims, liens or encumbrances;

               (iii)  The Company's authorized equity capitalization is as set
          forth in the Prospectus; the capital stock of the Company conforms to
          the description thereof contained in the Prospectus in all material
          respects; the statements in the Prospectus Supplement under the
          caption "Description of Preferred Stock and Depositary Shares" and in
          the Prospectus under the captions "Description of Preferred Stock" and
          "Description of the Depositary Shares," insofar as such statements
          constitute summaries of the documents referred to therein, have been
          reviewed by me and fairly summarize the matters referred to therein in
          all material respects; the outstanding shares of Common Stock and
          Series A Stock and Series D Stock have been duly and validly
          authorized and issued and are fully paid and nonassessable and the
          deposit of the Preferred Shares in accordance with the Deposit
          Agreement has been duly authorized; the Shares and the Preferred
          Shares have been duly and validly authorized, and, when issued and
          delivered pursuant to the Agreement and the Deposit Agreement and, in
          the case of the Shares, paid for by the Underwriters pursuant to the
          Agreement, will be fully paid and nonassessable; the Shares have been
          duly authorized for listing, subject to official notice of issuance,
          on the American Stock Exchange; the forms of certificates for the
          Shares are in valid and sufficient form in compliance with the
          American Stock Exchange requirements; and the holders of outstanding
          shares of capital stock of the Company are not entitled to preemptive
          or other rights to subscribe for the Shares or the Preferred Shares;

               (iv)    To the best of my knowledge, after due inquiry, there is
          no pending or threatened action, suit or proceeding before any court
          or governmental agency, authority or body or arbitrator involving the
          Company or the Operating Partnership of a character required to be
          disclosed in the Registration Statement

                                      -18-


          which is not adequately disclosed in the Prospectus, and there is no
          franchise, contract or other document of a character required to be
          described in the Registration Statement or Prospectus, or to be filed
          as an exhibit, which is not described or filed as required; and, to
          the best of my knowledge, after due inquiry, the statements in the
          Company's Quarterly Report on Form 10-Q for the quarterly period ended
          September 30, 2001, under Part I, Item 2 - "Management's Discussion
          and Analysis of Financial Condition and Results of Operations -
          Liquidity and Capital Resources - Distributions" and the Company's
          Annual Report on Form 10-K for the fiscal year ended December 31,
          2000, under Part III, Item 13 - "Certain Relationships and Related
          Transactions" (other than the financial statements and other financial
          and statistical information contained therein, as to which I need not
          express any opinion) fairly summarize the matters therein described in
          all material respects;

               (v)    The Registration Statement and the Prospectus and any
          amendment or supplement thereto comply as to form in all material
          respects with the requirements for the use of Form S-3 and the rules
          and regulations thereunder, and the Registration Statement and the
          Prospectus and any amendment or supplement thereto (other than the
          financial statements and other financial information contained
          therein, as to which I need express no opinion) comply as to form in
          all material respects with the requirements of the Act and the rules
          thereunder and each of the documents incorporated therein by reference
          (or, if any amendment with respect to any such document was filed,
          when such document was filed), complied as to form in all material
          respects with the requirements of the Exchange Act and the rules
          thereunder (other than the financial statements and other financial
          information contained therein, as to which I need express no opinion);

               (vi)   The Company has full corporate power and authority to
          enter into and perform its obligations under the Agreement and the
          Deposit Agreement and to issue, sell and deliver the Shares and to
          issue and deliver the Preferred Shares; the Agreement has been, and
          the Deposit Agreement will have been as of the Closing Date, duly
          authorized, executed and delivered by the Company; the Operating
          Partnership has full partnership, power and authority to enter into
          and to perform its obligations under the Agreement; and the Agreement
          has been duly authorized, executed and delivered by the Operating
          Partnership;

               (vii)  No consent, approval, authorization or order of any court
          or governmental agency, authority or body is required for the
          execution of the Agreement or the Deposit Agreement by the Primary
          Entities which are parties thereto, the performance by such Primary
          Entities of their obligations thereunder or the consummation of the
          transactions contemplated herein or therein, except such as have been
          obtained under the Act and the Exchange Act and such as may be
          required under the Blue Sky laws of any jurisdiction in connection
          with the purchase and distribution by the Underwriters of the Shares;

                                      -19-


               (viii) The Company and the Operating Partnership have all
          requisite power and authority, and, to the best of my knowledge, after
          due inquiry, all necessary material authorizations, approvals, orders,
          licenses, certificates and permits of and from all regulatory or
          governmental officials, bodies and tribunals, to own or lease their
          respective properties and to conduct their respective businesses as
          now being conducted and as described in the Prospectus; and, to the
          best of my knowledge, after due inquiry, all such authorizations,
          approvals, licenses, certificates and permits are in full force and
          effect, except where the failure to be in full force and effect would
          not have a Material Adverse Change, and the Company and the Operating
          Partnership are complying with all applicable laws, the violation of
          which could have a Material Adverse Change;

               (ix)   The Company is not in violation of its articles of
          incorporation or by-laws, and the Operating Partnership is not in
          violation of its partnership agreement, and to the best of my
          knowledge, after due inquiry, neither the Company nor the Operating
          Partnership is in default in the performance of any obligation,
          agreement or condition contained in any loan, note or other evidence
          of indebtedness or in any indenture, mortgage, deed of trust or any
          other material agreement by which it or its properties are bound,
          except for such defaults as could not, individually or the aggregate,
          have a Material Adverse Change;

               (x)    Neither the issue and sale of the Shares nor the
          consummation of any of the other transactions contemplated by the
          Agreement (including without limitation the execution, delivery and
          performance of the Deposit Agreement, the issuance and deposit of the
          Preferred Shares in accordance with the Deposit Agreement and the
          consummation of the transactions contemplated therein) nor the
          fulfillment of the terms hereof or thereof will conflict with, result
          in a breach or violation of, or constitute a default under any law or
          the articles of incorporation or by-laws of the Company or the
          partnership agreement of the Operating Partnership or the terms of any
          indenture or other agreement or instrument known to me and to which
          the Company or the Operating Partnership is a party or is bound or any
          judgment, order or decree known to me to be applicable to the Company
          or the Operating Partnership of any court, regulatory body,
          administrative agency, governmental body or arbitrator having
          jurisdiction over the Company or the Operating Partnership;

               (xi)   No holders of securities of the Company have rights to the
          registration of such securities under the Registration Statement,
          except as provided therein;

               (xii)  Any required filing of the Prospectus, including any
          supplements thereto, pursuant to Rule 424(b) has been made in the
          manner and within the time period required by Rule 424(b); and, to the
          best of my knowledge, no stop order suspending the effectiveness of
          the Registration Statement has been issued and no proceedings for that
          purpose have been instituted or threatened;

                                      -20-


               (xiii)  To the best of my knowledge, after due inquiry, neither
          the Company nor the Operating Partnership is in violation of any law,
          ordinance, administrative or governmental rule or regulation
          applicable to the Company or the Operating Partnership or of any
          decree of any court or governmental agency or body having jurisdiction
          over the Company or the Operating Partnership, the violation of which
          could have a Material Adverse Change;

               (xiv)   The statements in the Registration Statement and
          Prospectus, insofar as they are descriptions of contracts, agreements
          or other legal documents, or refer to statements of law or legal
          conclusions, are accurate and present fairly the information required
          to be shown in all material respects;

               (xv)    The Company and the Operating Partnership own or have the
          right to use all patents, trademarks, trademark registrations, service
          marks, service mark registrations, trade names, copyrights, licenses,
          inventions, trade secrets and rights described in the Prospectus as
          being owned by them or any of them or necessary for the conduct of
          their respective businesses, and, other than routine proceedings which
          if adversely determined would not materially affect the business of
          the Company and the Operating Partnership taken as a whole as
          described in the Prospectus, to the best of my knowledge, there is no
          claim to the contrary or any challenge by any other person to the
          rights of the Company and the Operating Partnership with respect to
          the foregoing;

               (xvi)   Except as described in the Prospectus, to the best of my
          knowledge, after due inquiry, there are no outstanding options,
          warrants or other rights calling for the issuance of, and there are no
          commitments, plans or arrangements to issue, any shares of capital
          stock of the Company or any security convertible into or exchangeable
          or exercisable for capital stock of the Company;

               (xvii)  Except as described in the Prospectus, to the best of my
          knowledge, after due inquiry, there is no holder of any security of
          the Company or any other person who has the right, contractual or
          otherwise, to cause the Company to sell or otherwise issue to them, or
          to permit them to underwrite the sale of, the Shares or the Preferred
          Shares or the right to have any Common Stock or other securities of
          the Company included in the Registration Statement or the right, as a
          result of the filing of the Registration Statement, to require
          registration under the Act of any shares of Common Stock or other
          securities of the Company;

               (xviii) Assuming due authorization, execution and delivery by
          the Depositary, the Deposit Agreement constitutes the valid and
          binding agreement of the Company, enforceable against the Company in
          accordance with its terms, except to the extent that enforcement
          thereof may be limited by (i) bankruptcy, insolvency, reorganization,
          moratorium or other similar laws now or hereafter in effect relating
          to creditors' rights generally and (ii) general principles of equity
          and (regardless of whether a proceeding is considered at law or in
          equity);

                                      -21-


               (xix)  When the Shares evidenced by the Depositary Receipts are
          issued and delivered in accordance with the terms of the Deposit
          Agreement against the deposit of duly authorized and issued, fully
          paid and nonassessable shares of Preferred Stock, the Depositary
          Receipts will entitle the holders thereof to the benefits provided
          therein and in the Deposit Agreement.

     In addition, such counsel shall state that he has participated in
conferences with representatives of the Underwriters, and with officers and
other representatives of the Company and representatives of the independent
certified public accountants of the Company, at which conferences the contents
of the Registration Statement and the Prospectus and related matters were
discussed and, although such counsel does not pass upon and does not assume any
responsibility for the accuracy, completeness or fairness of the statements
contained in the Registration Statement and the Prospectus, on the basis of the
foregoing (relying as to certain factual matters on the information provided to
such counsel by the Company and not on an independent investigation, but in the
absence of information to the contrary), no facts have come to such counsel's
attention which leads such counsel to believe that the Registration Statement,
as of its effective date, contained an untrue statement of a material fact or
omitted to state a material fact required to be stated therein or necessary to
make the statements therein not misleading, or that the Prospectus, as of its
date and as of the date hereof, contained an untrue statement of a material fact
or omitted to state a material fact necessary to make the statements therein, in
the light of the circumstances under which they were made, not misleading;
provided that such counsel need not express any comment with respect to the
- --------
financial statements and other financial data included in the Registration
Statement or Prospectus.

          (e) The Underwriters shall have received an opinion, dated the Closing
     Date and satisfactory in form and substance to counsel for the
     Underwriters, from Hogan & Hartson L.L.P., counsel for the Company, to the
     effect that:

               (i)   The Company was organized and has operated in conformity
          with the requirements for qualification and taxation as a real estate
          investment trust ("REIT") under the Code for the taxable year ended
          December 31, 2001, and the Company's current organization and method
          of operation (as described in the Prospectus, the Prospectus
          Supplement and the management representation letter) will enable it to
          continue to meet the requirements for qualification and taxation as a
          REIT; and

               (ii)  The statements in the Prospectus under the heading "Certain
          Federal Income Tax Considerations" and in the Company's Form 10-Q for
          the quarterly period ended September 30, 2001 under the heading "Item
          2A - Risk Factors - We would incur adverse tax consequences if we fail
          to qualify as a REIT" read in conjunction with the statements in the
          Prospectus Supplement under the heading "Federal Income Tax
          Consequences,"  to the extent they describe matters of federal income
          tax law or federal income tax legal conclusions, are correct in all
          material respects.

          (f) The Underwriters shall have received an opinion, dated the Closing
     Date from Hale and Dorr LLP, counsel to the Underwriters, with respect to
     the Registration

                                      -22-


     Statement, the Prospectus and this Agreement, which opinion shall be

     they may reasonably request to enable them to pass on such matters.

          (g) You shall have received letters addressed to you, as
     Representatives of the several Underwriters, and dated the date hereof and
     the Closing Date from Ernst & Young LLP, independent certified public
     accountants, substantially in the forms heretofore approved by you.

          (h) (i) No stop order suspending the effectiveness of the Registration
     Statement shall have been issued and no proceedings for that purpose shall
     have been taken or, to the knowledge of the Company, shall be contemplated
     by the Commission at or prior to the Closing Date; (ii) there shall not
     have been any material change in the capital stock 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 Primary Entities
     taken as a whole; (iv) the Primary Entities shall not have any liabilities
     or obligations, direct or contingent (whether or not in the ordinary course
     of business), that are material to the Primary Entities, 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 Primary Entities contained in this Agreement shall be
     true and correct in all material respects 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 signed by
     the chief executive officer and the chief financial officer of the Company
     (or such other officers as are acceptable to you), to the effect set forth
     in this Section 6(h) and in Section 6(i) hereof.

          (i) The Company shall not in any material respect have failed at or
     prior to the Closing Date to have performed or complied with any of its
     agreements herein contained or contained in the Deposit Agreement and
     required to be performed or complied with by it hereunder or thereunder at
     or prior to the Closing Date.

          (j) Prior to the Closing Date the Shares shall have been listed,
     subject to notice of issuance, on the American Stock Exchange.

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

          (l) Subsequent to the Execution Time, there shall not have been any
     decrease in the rating of any of the Company's debt securities by any
     "nationally recognized

                                      -23-


     statistical rating organization" (as defined for purposes of Rule 436(g)
     under the Act) or any notice given of any intended or potential decrease in
     any such rating or of a possible change in any such rating that does not
     indicate the direction of the possible change.

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

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

7.   Indemnification and Contribution.
     --------------------------------

          (a) The Primary Entities, jointly and severally, agree to indemnify
     and hold harmless you and each other Underwriter and each person, if any,
     who controls any 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 Preliminary 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 such Underwriter
     furnished in writing to the Company by or on behalf of any Underwriter
     through you expressly for use in connection therewith; provided, however,
     that with respect to any untrue statement or omission of material fact made
     in any Preliminary Prospectus, the indemnity agreement contained in this
     Section 7(a) shall not inure to the benefit of any Underwriter from whom
     the person asserting any such loss, claim, damage or liability purchased
     the securities concerned, to the extent that any such loss, claim, damage
     or liability of such Underwriter occurs under the circumstance where it
     shall have been determined by a court of competent jurisdiction by final
     and nonappealable judgment that (w) the Company had previously furnished
     copies of the Prospectus to the Representatives, (x) delivery of the
     Prospectus was required by the Act to be made to such person, (y) the
     untrue statement or omission of a material fact contained in the
     Preliminary Prospectus was corrected in the Prospectus and (z) there was
     not sent or given to such person, at or prior to the written confirmation
     of the sale of such securities to such person, a copy of the Prospectus.

          (b) If any action, suit or proceeding shall be brought against any
     Underwriter or any person controlling any Underwriter in respect of which
     indemnity may be sought against the Primary Entities, such Underwriter or
     such controlling person shall promptly notify the Company (but failure to
     so notify the Company shall not relieve the Company

                                      -24-


     from any liability hereunder to the extent it is not materially prejudiced
     as a result thereof and in any event shall not relieve it from any
     liability which it may have otherwise than on account of this indemnity
     agreement) and the Company shall assume the defense thereof, including the
     employment of counsel and payment of all fees and expenses; provided,
     however, that if the defendants in any such action include both the
     indemnified party and the indemnifying party and the indemnified party
     shall have reasonably concluded that there may be one or more legal
     defenses available to it and/or other indemnified parties which are
     different from or additional to those available to the indemnifying party,
     the indemnifying party shall not have the right to direct the defense of
     such action on behalf of such indemnified party or parties and such
     indemnified party or parties shall have the right to select separate
     counsel to defend such action on behalf of such indemnified party or
     parties. Such 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 such Underwriter or such controlling
     person unless (i) the Primary Entities jointly and severally have agreed in
     writing to pay such fees and expenses, (ii) the Company has failed promptly
     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 such Underwriter or such controlling person and a Primary Entity and
     such Underwriter or such controlling person shall have been advised by its
     counsel that representation of such indemnified party and a Primary Entity
     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 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 all such Underwriters and controlling persons not
     having actual or potential differing interests with you or among
     themselves, which firm shall be designated in writing by Salomon Smith
     Barney Inc., and that all such fees and expenses shall be reimbursed as
     they are incurred. The Primary Entities shall not be liable for any
     settlement of any such action, suit or proceeding effected without the
     Company's written consent, but if settled with such written consent, or if
     there be a final judgment for the plaintiff in any such action, suit or
     proceeding, the Primary Entities jointly and severally agree to indemnify
     and hold harmless any 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) Each Underwriter agrees, severally and not jointly, to indemnify
     and hold harmless the Company, its directors, its 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 to each
     Underwriter, but only with respect to information relating to such
     Underwriter furnished in writing by or on behalf of such Underwriter
     through you

                                      -25-


     expressly for use in the Registration Statement, the Prospectus or any
     Preliminary Prospectus, or any amendment or supplement thereto. If any
     action, suit or proceeding shall be brought against the Company, any of its
     directors, any such officer, or any such controlling person based on the
     Registration Statement, the Prospectus or any Preliminary Prospectus, or
     any amendment or supplement thereto, and in respect of which indemnity may
     be sought against any Underwriter pursuant to this paragraph (c), such
     Underwriter shall have the rights and duties given to the Company by
     paragraph (b) above (except that if the Company 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 such Underwriter's
     expense), and the Company, its directors, any such officer, and any such
     controlling person shall have the rights and duties given to the
     Underwriters by paragraph (b) above. The foregoing indemnity agreement
     shall be in addition to any liability which the Underwriters may otherwise
     have.

          (d) If the indemnification provided for in this Section 7 is
     unavailable to an indemnified party under paragraph (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 Primary Entities on the one hand and the
     Underwriters 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
     Primary Entities on the one hand and the Underwriters 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 Primary
     Entities on the one hand and the Underwriters 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 bear to the total
     underwriting discounts and commissions received by the Underwriters, in
     each case as set forth in the table on the cover page of the Prospectus.
     The relative fault of the Primary Entities on the one hand and the
     Underwriters 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 Primary Entities on the one hand or by the
     Underwriters 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 Primary Entities, on the one hand and the Underwriters, on the
     other hand, agree that it would not be just and equitable if contribution
     pursuant to this Section 7 were determined by a pro rata allocation (even
     if the Underwriters were treated as one entity for such purpose) 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

                                      -26-


     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 7, no Underwriter shall be required to
     contribute any amount in excess of the amount by which the total price of
     the Shares underwritten by it and distributed to the public 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.
     The Underwriters' obligations to contribute pursuant to this Section 7 are
     several in proportion to the respective numbers of Shares set forth
     opposite their names in Schedule I hereto and not joint.

          (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 and does not include a
     statement as to or an admission of fault, culpability or a failure to act
     by or on behalf of any indemnified party.

          (g) If at any time an indemnified party shall have requested an
     indemnifying party to reimburse the indemnified party for fees and expenses
     of counsel, such indemnifying party agrees that it shall be liable for any
     settlement of the nature contemplated by Section 7(b) effected without its
     written consent if (i) such settlement is entered into more than 45 days
     after receipt by such indemnifying party of the aforesaid request, (ii)
     such indemnifying party shall have received notice of the terms of such
     settlement at least 30 days prior to such settlement being entered into and
     (iii) such indemnifying party shall not have reimbursed such indemnified
     party in accordance with such request prior to the date of such settlement.
     Notwithstanding the immediately preceding sentence, if at any time an
     indemnified party shall have requested an indemnifying party to reimburse
     the indemnified party for fees and expenses of counsel, an indemnifying
     party shall not be liable for any settlement of the nature contemplated by
     Section 7(b) effected without its consent if such indemnifying party (i)
     reimburses such indemnified party in accordance with such request to the
     extent such indemnifying party considers such request to be reasonable and
     (ii) provides written notice to the indemnified party substantiating the
     unpaid balance as unreasonable, in each case prior to the date of such
     settlement.

          (h) Any losses, claims, damages, liabilities or expenses for which an
     indemnified party is entitled to indemnification or contribution under this
     Section 7 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 7 and the
     representations and warranties of the Company 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 any Underwriter or any person
     controlling

                                      -27-


     any Underwriter, the Company, its directors or officers, or any person
     controlling the Company, (ii) acceptance of any Shares and payment therefor
     hereunder, and (iii) any termination of this Agreement. A successor to any
     Underwriter or any person controlling any Underwriter, or to the Company,
     its directors or officers, or any person controlling the Company, shall be
     entitled to the benefits of the indemnity, contribution and reimbursement
     agreements contained in this Section 7.

8.   Expenses.
     --------

     The Company agrees to pay the following costs and expenses and all other
costs and expenses incident to the performance by it of its obligations
hereunder: (i) the preparation, printing or reproduction, and filing with the
Commission of the Registration Statement (including financial statements and
exhibits thereto) and the Prospectus, including each amendment or supplement to
any of them; (ii) the printing (or reproduction) and delivery (including
postage, air freight charges and charges for counting and packaging) of such

any of them, as may be reasonably requested for use in connection with the
offering and sale of the Shares; (iii) the preparation, printing,
authentication, issuance and delivery of certificates for the Shares and the
Preferred Shares, including any stamp taxes in connection with the original
issuance and sale of the Shares and the Preferred Shares; (iv) the printing (or
reproduction) and delivery of this Agreement, the preliminary and supplemental
Blue Sky Memoranda, the Deposit Agreement and all other agreements or documents
printed (or reproduced) and delivered in connection with the offering of the
Shares and the Preferred Shares; (v) the fees and expenses of the Depositary,
including the fees and disbursements of counsel for the Depositary, if any; (vi)
the registration of the Shares under the Exchange Act and the listing of the
Shares on the American Stock Exchange; (vii) the registration or qualification
of the Shares and the Preferred Shares for offer and sale under the securities
or Blue Sky laws of the several states as provided in Section 5(f) hereof
(including the reasonable fees, expenses and disbursements of counsel for the
Underwriters relating to the preparation, printing or reproduction, and delivery
of the preliminary and supplemental Blue Sky Memoranda and such registration and
qualification); (viii) the filing fees and the fees and expenses of counsel for
the Underwriters in connection with any filings required to be made with the
National Association of Securities Dealers, Inc.; (ix) the transportation and
other expenses incurred by or on behalf of Company representatives in connection
with presentations to prospective purchasers of the Shares; and (x) the fees and
expenses of the Company's accountants and the fees and expenses of counsel
(including local and special counsel) for the Company.

9.   Effective Date of Agreement.
     ---------------------------

     This Agreement shall become effective: (i) upon the execution and delivery
hereof by the parties hereto; or (ii) if, at the time this Agreement is executed
and delivered, it is necessary for a post-effective amendment to the
Registration Statement to be declared or become effective before the offering of
the Shares may commence, when notification of the effectiveness of 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 by you, as Representatives of the several Underwriters, by
notifying the Company.

                                      -28-


     If any one or more of the Underwriters shall fail or refuse to purchase
Shares which it or they are obligated to purchase hereunder on the Closing Date,
and the aggregate number of Shares which such defaulting Underwriter or
Underwriters are obligated but fail or refuse to purchase is not more than one-
tenth of the aggregate number of Shares which the Underwriters are obligated to
purchase on the Closing Date, each non-defaulting Underwriter shall be
obligated, severally, in the proportion which the number of Shares set forth
opposite its name in Schedule I hereto bears to the aggregate number of Shares
set forth opposite the names of all non-defaulting Underwriters or in such other
proportion as you may specify in accordance with Section 11 of the Master
Agreement Among Underwriters of Salomon Smith Barney Inc., to purchase the
Shares which such defaulting Underwriter or Underwriters are obligated, but fail
or refuse, to purchase. If any one or more of the Underwriters shall fail or
refuse to purchase Shares which it or they are obligated to purchase on the
Closing Date and the aggregate number of Shares with respect to which such
default occurs is more than one-tenth of the aggregate number of Shares which
the Underwriters are obligated to purchase on the Closing Date and arrangements
satisfactory to you and the Company for the purchase of such Shares by one or
more non-defaulting Underwriters or other party or parties approved by you and
the Company are not made within 36 hours after such default, this Agreement will
terminate without liability on the part of any non-defaulting Underwriter or the
Company. In any such case which does not result in termination of this
Agreement, either you or the Company shall have the right to postpone the
Closing Date, but in no event for longer than seven days, in order that the
required changes, if any, in the Registration Statement and the Prospectus or
any other documents or arrangements may be effected. Any action taken under this
paragraph shall not relieve any defaulting Underwriter from liability in respect
of any such default of any such Underwriter under this Agreement. The term
"Underwriter" as used in this Agreement includes, for all purposes of this
Agreement, any party not listed in Schedule I hereto who, with your approval and
the approval of the Company, purchases Shares which a defaulting Underwriter is
obligated, but fails or refuses, to purchase.

     Any notice under this Section 9 may be given by telegram, telecopy or
telephone but shall be subsequently confirmed by letter.

10.  Termination.
     -----------

     This Agreement shall be subject to termination in your absolute discretion,
without liability on the part of any Underwriter to the Company by notice to the
Company, if prior to the Closing Date, (i) there has been, since the time of
execution of this Agreement or since the respective dates as of which
information is given in the Prospectus, any material adverse change, or any
development involving a prospective material adverse change, in the condition,
financial or otherwise, or in the business, properties, net worth or results of
operations of the Company or the Operating Partnership, whether or not arising
in the ordinary course of business, (ii) trading in securities generally on the
New York Stock Exchange, the American Stock Exchange or the Nasdaq National
Market shall have been suspended or materially limited, (iii) a general
moratorium on commercial banking activities in New York or California shall have
been declared by either federal or state authorities, or (iv) there shall have
occurred any outbreak or escalation of hostilities or other international or
domestic calamity, crisis or change in political, financial or economic
conditions, the effect of which on the financial markets of the United States is
such as to make it, in your judgment, impracticable or inadvisable to commence
or

                                      -29-


continue the offering of the Shares at the offering price to the public set
forth on the cover page of the Prospectus or to enforce contracts for the resale
of the Shares by the Underwriters. Notice of such termination may be given to
the Company by telegram, telecopy or telephone and shall be subsequently
confirmed by letter.

11.  Information Furnished by the Underwriters.
     -----------------------------------------

     The statements set forth in the last paragraph on the cover page and in the
first, second, third, seventh, eighth, ninth and twelfth paragraphs under the
caption "Underwriting" in the Prospectus Supplement constitute the only
information furnished by or on behalf of the Underwriters through you as such
information is referred to in Sections 3(b) and 7 hereof.

12.  Miscellaneous.
     -------------

     Except as otherwise provided in Sections 3, 9 and 10 hereof, notice given
pursuant to any provision of this Agreement shall be in writing and shall be

     This Agreement has been and is made solely for the benefit of the several
Underwriters, the Primary Entities, their respective directors and officers, and
the other controlling persons referred to in Section 7 hereof and their
respective successors and assigns, to the extent provided herein, and no other
person shall acquire or have any right under or by virtue of this Agreement.
Neither the term "successor" nor the term "successors and assigns" as used in
this Agreement shall include a purchaser from any Underwriter of any of the
Shares in his status as such purchaser.

13.  Applicable Law; Counterparts.
     ----------------------------

     This agreement shall be governed by and construed in accordance with the
laws of the State of New York, including without limitation Section 5-1401 of
the New York General Obligations Law.

constitute one and the same instrument. If signed in counterparts, this
Agreement shall not become effective unless at least one counterpart hereof
shall have been executed and delivered on behalf of each party hereto.

                                      -30-


     If the foregoing is in accordance with your understanding of our agreement,
