Ladies and Gentlemen:

      Vornado  Realty  Trust,  a  Maryland  real  estate  investment  trust (the
"Company"),  confirms its agreement with Merrill Lynch  International  ("Merrill
Lynch")  and each of the other  international  underwriters  named in Schedule A
hereto  (collectively,  the  "International  Managers",  which  term  shall also
include  any  underwriter  substituted  as  hereinafter  provided  in Section 10
hereof), for whom Merrill Lynch,  Goldman Sachs International,  Furman Selz LLC,
Salomon Brothers  International  Limited,  Smith Barney Inc. and UBS Limited are
acting as representatives (in such capacity, the "Lead Managers"),  with respect
to the issue  and sale by the  Company  and the  purchase  by the  International
Managers,  acting severally and not jointly, of the respective numbers of Common
Shares of  Beneficial  Interest,  par  value  $0.04 per  share,  of the  Company
("Common Shares") set forth in said Schedule A, and with respect to the grant by
the Company to the International Managers,  acting severally and not jointly, of
the  option   described   in  Section   2(b)  hereof  to  purchase  all  or  any


                                       1




part of 420,000 additional Common Shares to cover  over-allotments,  if any. The
aforesaid 2,800,000 Common Shares (the "Initial International Securities") to be
purchased  by the  International  Managers  and all or any  part of the  420,000
Common  Shares  subject to the option  described  in Section  2(b)  hereof  (the
"International  Option  Securities") are hereinafter called,  collectively,  the
"International Securities".

      It is  understood  that  the  Company  is  concurrently  entering  into an
agreement dated the date hereof (the "U.S.  Purchase  Agreement")  providing for
the  offering by the Company of an aggregate of  11,200,000  Common  Shares (the
"Initial U.S. Securities") through arrangements with certain underwriters in the
United  States and Canada (the "U.S.  Underwriters")  for which  Merrill  Lynch,
Pierce,  Fenner & Smith  Incorporated,  Goldman,  Sachs & Co.,  Furman Selz LLC,
Salomon  Brothers Inc,  Smith Barney Inc. and UBS  Securities  LLC are acting as
representatives (the "U.S. Representatives") and the grant by the Company to the
U.S.  Underwriters,  acting severally and not jointly,  of an option to purchase
all or any part of up to  1,680,000  additional  Common  Shares  solely to cover
overallotments,  if any (the "U.S.  Option  Securities"  and,  together with the
International  Option  Securities,  the "Option  Securities").  The Initial U.S.
Securities  and the U.S.  Option  Securities  are  hereinafter  called the "U.S.
Securities".  It is understood that the Company is not obligated to sell and the
International  Managers are not obligated to purchase, any Initial International
Securities  unless all of the  Initial  U.S.  Securities  are  contemporaneously
purchased by the U.S. Underwriters.

      The  International  Managers  and the U.S.  Underwriters  are  hereinafter
collectively called the "Underwriters", the Initial International Securities and
the Initial U.S.  Securities are  hereinafter  collectively  called the "Initial
Securities",  and the  International  Securities  and the  U.S.  Securities  are
hereinafter collectively called the "Securities".

      The Underwriters will concurrently enter into an Intersyndicate  Agreement
of  even  date  herewith  (the  "Intersyndicate  Agreement")  providing  for the
coordination of certain  transactions among the Underwriters under the direction
of Merrill Lynch & Co., Merrill Lynch,  Pierce,  Fenner & Smith Incorporated (in
such capacity, the "Global Coordinator").

      The Company understands that the International  Managers propose to make a
public  offering of the  International  Securities  as soon as the Lead Managers
deem advisable after this Agreement has been executed and delivered.

      The Company has filed with the  Securities  and Exchange  Commission  (the
"Commission")  one or more  registration  statements  on Form S-3,  including  a
prospectus relating to the Common Shares and other securities of the Company for
the registration of such securities under the Securities Act of 1933, as amended
(the "1933 Act"). Such registration  statements have been declared  effective by
the   Commission.   A  prospectus   supplement   reflecting  the  terms  of  the
International  Securities,  the  terms of the  offering  thereof  and the  other
matters set forth therein has been prepared or will be prepared. Such prospectus
supplement is  hereinafter  called the  "International  Prospectus  Supplement."
Concurrently with the preparation of the International  Prospectus Supplement, a
prospectus supplement reflecting the terms of the U.S. Securities, the terms  of
the offering  thereof and the other  matters set forth therein has been prepared
or will be prepared and will be filed in accordance with the provisions of  Rule
424(b) 


                                       2



("Rule  424(b)") of the rules and  regulations of the Commission  under the 1933
Act (the "1933 Act Regulations").  Such prospectus supplement, in the form first
filed after the date hereof pursuant to Rule 424(b),  is hereinafter  called the
"U.S. Prospectus Supplement." The International  Prospectus  Supplement and  the
U.S. Prospectus  Supplement are hereinafter  collectively called the "Prospectus
Supplements."  Such  registration  statements,  as amended  at the date  hereof,
including all documents  incorporated  or deemed to be incorporated by reference
therein and the exhibits thereto, and schedules thereto, if any, are hereinafter
called the  "Registration  Statement" and the basic prospectus  included therein
and relating to all offerings of securities under the Registration Statement, as
supplemented by the International  Prospectus  Supplement is hereinafter  called
the  "International  Prospectus"  and as  supplemented  by the  U.S.  Prospectus
Supplement is hereinafter  called the "U.S.  Prospectus"  and the  International
Prospectus  and the  U.S.  Prospectus  are  hereinafter  called,  together,  the
"Prospectuses",  except that if such basic prospectus is amended or supplemented
on or prior to the date on which the  Prospectus  Supplements  are  first  filed
pursuant  to Rule  424(b),  the term  "Prospectuses"  shall  refer to the  basic
prospectus as so amended or  supplemented  and as supplemented by the Prospectus
Supplements,  in either case  including the documents  filed by the Company with
the Commission  pursuant to the Securities Exchange Act of 1934, as amended (the
"1934 Act"),  that are incorporated by reference  therein.  For purposes of this
Agreement,  all references to the Registration  Statement or the Prospectuses or
any  amendment  or  supplement  to  either of the  foregoing  shall be deemed to
include  the copy filed with the  Commission  pursuant  to its  Electronic  Data
Gathering, Analysis and Retrieval System ("EDGAR").

      All references in this Agreement to financial statements and schedules and
other  information  which is  "contained,"  "included,"  "stated,"  "described,"
"discussed" or "set forth" in the Registration Statement or the Prospectuses (or
other  references  of like import)  shall be deemed to mean and include all such
financial  statements and schedules and other  information which is incorporated
by reference in the Registration Statement or the Prospectuses,  as the case may
be; and all  references in this  Agreement to amendments or  supplements  to the
Registration  Statement, or the Prospectuses shall be deemed to mean and include
the filing of any document under the 1934 Act which is incorporated by reference
in the Registration Statement or the Prospectuses, as the case may be.

      For purposes of this Agreement, unless the context requires otherwise, all
references to  "subsidiaries"  shall include  preferred stock  affiliates of the
Company in which the Company owns all of the outstanding preferred equity.

      business affairs or business prospects of the Company and its subsidiaries
      taken as a whole;  and, to the best of the  Company's  knowledge,  no such
      proceedings are threatened or contemplated by governmental  authorities or
      threatened  by others;  and there are no  contracts  or  documents  of the
      Company  or any of its  subsidiaries  which  are  required  to be filed as
      exhibits  to the  Registration  Statement  by the 1933 Act or the 1933 Act
      Regulations which have not been so filed;

          (xii)   Neither  the  Company  nor  any  of  its  subsidiaries  is  in
      violation  of its  charter  documents  or  by-laws  or in  default  in the
      performance or observance of any material obligation,  agreement, covenant
      or condition contained in any material indenture, mortgage, deed of trust,
      loan  agreement,  lease or other  agreement or instrument to which it is a
      party or by which it or any of its  properties  or  assets  may be  bound,
      which default would have a material adverse effect on the general affairs,
      management,   financial  position,  shareholders'  equity  or  results  of
      operations of the Company and its subsidiaries;

         (xiii)   The  statements  set  forth  in  the  Prospectuses  under  the
      captions "Description of Shares of Beneficial  Interest",  "Federal Income
      Tax Considerations", "Plan of Distribution" and "Underwriting", insofar as
      they purport to describe the provisions of the laws and documents referred
      to therein, are accurate, complete and fair summaries;

          (xiv)   Neither the Company nor any of its  subsidiaries is subject to
      registration as an "investment  company" under the Investment  Company Act
      of 1940, as amended (the "Investment Company Act");

           (xv)   Deloitte & Touche LLP, who have  certified  certain  financial
      statements  and  financial  statement  schedules  of the  Company  and its
      subsidiaries  included or  incorporated  by reference in the  Registration
      Statement,  are independent public accountants as required by the 1933 Act
      and the 1933 Act Regulations;

          (xvi)   The financial statements and the financial statement schedules
      included or  incorporated by reference in the  Registration  Statement and
      the Prospectuses  present fairly the financial position of the Company and
      its  consolidated  subsidiaries as at the dates indicated, the results of
      their operations for the periods specified and the information required to
      be stated therein;  and said financial  statements and financial statement
      schedules  have  been  prepared  in  conformity  with  generally  accepted
      accounting principles applied on a consistent basis throughout the periods
      involved.   The  selected  financial  data  included  or  incorporated  by
      reference in the Prospectuses present fairly the information shown therein
      and have been compiled on a basis consistent with that of the consolidated
      financial   statements  included  or  incorporated  by  reference  in  the
      Registration


                                        7





      Statement.  Any  pro  forma  financial  statements  and  other  pro  forma
      financial  information included in the Registration Statement and the Pro-
      spectuses comply in all material respects with the applicable requirements
      of Rule 11-02 of Regulation  S-X of the  Commission and present fairly the
      information shown therein;  the pro forma  adjustments,  if any, have been
      properly  applied to the  historical  amounts in the  compilation  of such
      statements, and in the opinion of the Company, the assumptions used in the
      preparation  thereof are reasonable and the  adjustments  used therein are
      appropriate to give effect to the transactions or  circumstances  referred
      to therein;

         (xvii)   Except as otherwise disclosed in the Prospectuses,  and except
      as 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 its subsidiaries taken as a whole: (i) each of the Company and
      its  subsidiaries  has good and  marketable  title to all  properties  and
      assets  described in the Prospectuses as owned by such party, in each case
      free of all liens,  encumbrances and defects; (ii) all of the leases under
      which the Company or any of its  subsidiaries  holds or uses real property
      or assets  as a lessee  are in full  force and  effect,  and  neither  the
      Company nor any of its  subsidiaries is in material  default in respect of
      any of the terms or provisions of any of such leases and no claim has been
      asserted by anyone  adverse to any such party's rights as lessee under any
      of such leases,  or affecting or questioning any such party's right to the
      continued  possession  or use of the leased  property or assets  under any
      such  leases;  (iii)  all  liens,   charges,   encumbrances,   claims,  or
      restrictions  on or affecting the  properties and assets of the Company or
      any of  its  subsidiaries  that  are  required  to  be  disclosed  in  the
      Prospectuses are disclosed therein;  (iv) neither the Company,  any of its
      subsidiaries  nor,  to the  knowledge  of the  Company,  any lessee of any
      portion of any such  party's  properties  is in  default  under any of the
      leases pursuant to which the Company or any of its subsidiaries leases its
      properties  and neither the Company nor any of its  subsidiaries  knows 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 leases;  (v) no tenant
      under any lease  pursuant to which the Company or any of its  subsidiaries
      leases its  properties has an option or right of first refusal to purchase
      the premises leased thereunder; (vi) to the best of its knowledge, each of
      the properties of the Company or any of its subsidiaries complies with all

      on or access to the properties of the Company or any of its subsidiaries;

        (xviii)   Except as otherwise  disclosed in the  Prospectuses,  or as is
      not reasonably  likely to have a material adverse effect on the condition,
      financial or  otherwise,  or the  earnings,  business  affairs or business
      prospects of the Company and its subsidiaries taken as a whole:


                                       8



                  A.  each of the Company and its  subsidiaries is in compliance
          with all  applicable  laws  relating to pollution or the  discharge of
          materials  into  the environment,  including  common  law  relating to
          damage to property or injury to persons  ("Environmental  Laws"). Each
          of the Company and its  subsidiaries  currently holds all governmental
          authorizations  required under Environmental Laws in order  to conduct
          their  businesses  as described in the  Prospectuses,  and none of the
          above  has  any   basis  to   believe   that  any  such   governmental
          authorization  may be  modified,  suspended or revoked,  or cannot  be
          renewed in the ordinary course of business;

                  B.  there  are  no  past  or  present   actions,   activities,
          circumstances,  conditions,  events or incidents,  including,  without
          limitation,  the  release,  threatened  release,  or  disposal  of any
          material (including radiation and noise), that could form the basis of
          any claim  (whether by a  governmental  authority  or other  person or
          entity)  under   Environmental   Laws  for  cleanup  costs,   damages,
          penalties,  fines,  or  otherwise,  against  any of the Company or its
          subsidiaries, or against any person or entity whose liability for such
          claim may have  been  retained  by any of the  Company  or its subsid-
          iaries, whether by contract or law; and

                  C.  the Company and its  subsidiaries  have fully disclosed to
          the  International  Managers and their  counsel all studies,  reports,
          assessments,  audits  and other  information  in their  possession  or
          control  relating to any pollution or release,  threatened  release or
          disposal  of  materials  regulated  under  Environmental  Laws on, at,
          under,  from or  transported  from any of their  currently or formerly
          owned, leased or operated properties,  including,  without limitation,
          all  information  relating to  underground  storage tanks and asbestos
          containing materials.

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

      (b) Officer's  Certificates.  Any certificate signed by any officer of the
Company or any of its subsidiaries delivered to the Global Coordinator, the Lead
Managers  or to  counsel  for the  International  Managers  shall  be  deemed  a
representation and warranty by the Company to each  International  Manager as to
the matters covered thereby.

      SECTION 2. Sale and Delivery to International Managers; Closing.
                 ----------------------------------------------------

      (a) Initial Securities. On the basis of the representations and warranties
herein  contained and subject to the terms and conditions  herein set forth, the
Company agrees to sell to each International Manager, severally and not jointly,
and each International  Manager,  severally and not jointly,  agrees to purchase
from the Company,  at the price per share set forth in Schedule B, the number of
Initial  International  Securities  set forth in Schedule A opposite the name of
such International  Manager, plus any additional number of Initial International


                                        9




Securities which such  Underwriter may become obligated to purchase  pursuant to
the provisions of Section 10 hereof.

      (b) Option Securities.  In addition,  on the basis of the  representations
and warranties  herein contained and subject to the terms and conditions  herein
set forth,  the Company hereby grants an option to the  International  Managers,
severally and not jointly, to purchase up to an additional 420,000 Common Shares
at the price per share set forth in  Schedule  B, less an amount per share equal
to any  dividends  or  distributions  declared by the Company and payable on the
Initial  International  Securities but not payable on the  International  Option
Securities.  The option hereby granted will expire 30 days after the date hereof
and may be  exercised in whole or in part from time to time only for the purpose
of covering  over-allotments  which may be made in connection  with the offering
and  distribution  of the Initial  International  Securities  upon notice by the
Global  Coordinator  to the Company  setting  forth the number of  International
Option  Securities  as to which  the  several  International  Managers  are then
exercising  the option and the time and date of payment  and  delivery  for such
International  Option  Securities.  Any such time and date of  delivery  for the
International  Option  Securities (a "Date of Delivery")  shall be determined by
the Global  Coordinator,  but shall not be later than seven full  business  days
after the exercise of said option,  nor in any event prior to the Closing  Time,
as hereinafter  defined.  If the option is exercised as to all or any portion of
the International Option Securities,  each of the International Managers, acting
severally and not jointly,  will purchase that proportion of the total number of
International Option Securities then being purchased which the number of Initial
International  Securities  set forth in  Schedule  A  opposite  the name of such
International  Manager  bears  to the  total  number  of  Initial  International
Securities,  subject in each case to such adjustments as the Global  Coordinator
in its  discretion  shall make to eliminate any sales or purchases of fractional
shares.

      (c)  Payment.   Payment  of  the  purchase  price  for,  and  delivery  of
certificates  for,  the  Initial  Securities  shall  be made at the  offices  of
Skadden,  Arps, Slate,  Meagher & Flom LLP, 919 Third Avenue, New York, NY 10022
or at such other place as shall be agreed upon by the Global Coordinator and the
Company, at 9:00 A.M. (Eastern time) on the third (fourth, if the pricing occurs
after 4:30 P.M.  (Eastern  time) on any given day)  business  day after the date
hereof  (unless  postponed in accordance  with the provisions of Section 10), or
such  other time not later  than ten  business  days after such date as shall be
agreed upon by the Global  Coordinator  and the  Company  (such time and date of
payment and delivery being herein called "Closing Time").

      In  addition,  in the event  that any or all of the  International  Option
Securities are purchased by the International Managers,  payment of the purchase
price  for,  and  delivery  of  certificates  for,  such  International   Option
Securities shall be made at the above-mentioned  offices, or at such other place
as shall be agreed upon by the Global Coordinator and the Company,  on each Date
of  Delivery  as  specified  in the notice  from the Global  Coordinator  to the
Company.


                                       10



      Payment  shall be made to the  Company  by wire  transfer  of  immediately
available funds to a bank account designated by the Company, against delivery to
the Lead Managers for the respective  accounts of the International  Managers of
certificates  for the  International  Securities  to be purchased by them. It is
understood that each International Manager has authorized the Lead Managers, for
its  account,  to accept  delivery  of,  receipt  for,  and make  payment of the
purchase price for, the Initial  International  Securities and the International
Option  Securities,  if any,  which it has agreed to  purchase.  Merrill  Lynch,
individually and not as representative of the International  Managers,  may (but
shall not be obligated  to) make  payment of the purchase  price for the Initial
International  Securities or the International Option Securities,  if any, to be
purchased by any International Manager whose funds have not been received by the
Closing  Time or the  relevant  Date of  Delivery,  as the case may be, but such
payment  shall not  relieve  such  International  Manager  from its  obligations
hereunder.

      (d)   Denominations;    Registration.   Certificates   for   the   Initial
International Securities and the International Option Securities,  if any, shall
be in such  denominations  and registered in such names as the Lead Managers may
request in writing at least one full business day before the Closing Time or the
relevant Date of Delivery,  as the case may be. The certificates for the Initial
International  Securities and the International Option Securities,  if any, will
be made available for examination and packaging by the Lead Managers in The City
of New York not later than 10:00 A.M.  (Eastern  time) on the business day prior
to the Closing Time or the relevant Date of Delivery, as the case may be.

      SECTION 3.  Covenants  of the  Company.  The Company  covenants  with each
International Manager as follows:

            (a)   Delivery of Registration Statements. The Company has furnished
      or will  deliver to the Lead  Managers  and counsel for the  International
      Managers,   without  charge,  copies  of  the  Registration  Statement  as
      originally filed and of each amendment thereto  (including  exhibits filed
      therewith or incorporated by reference therein and documents  incorporated
      or deemed to be  incorporated  by  reference  therein)  and  copies of all
      consents and  certificates  of experts,  and will also deliver to the Lead
      Managers,  without charge, a conformed copy of the Registration  Statement
      as originally filed and of each amendment  thereto (without  exhibits) for
      each  of the  International  Managers.  The  copies  of  the  Registration
      Statement  and  each  amendment  thereto  furnished  to the  International
      Managers  will  be  identical  to the  electronically  transmitted  copies
      thereof filed with the Commission  pursuant to EDGAR, except to the extent
      permitted by Regulation S-T.

                  During  the  period  when  the  International   Prospectus  is
      required by the 1933 Act to be delivered in  connection  with sales of the
      International Securities, the Company will inform the Lead Managers of its
      intention  to file any  amendment  to the  Registration  Statement  or any
      supplement to the International Prospectus; will furnish the Lead Managers
      with copies of any such  amendment  or  supplement  a  reasonable  time in
      advance of filing; and will not file any such amendment or supplement in a
      form to which the Lead Managers or counsel for the International  Managers
      shall reasonably  


                                       11



      object (it being understood that the terms "amendment" and "supplement" do
      not include documents filed by the Company pursuant to the 1934 Act).

            (b)   Delivery of  Prospectuses.  The Company has  delivered to each
      International Manager,  without charge, as many copies of each preliminary
      prospectus as such  International  Manager reasonably  requested,  and the
      Company hereby  consents to the use of such copies for purposes  permitted
      by the 1933 Act. The Company will furnish to each  International  Manager,
      without  charge,  during the period when the  International  Prospectus is
      required to be delivered  under the 1933 Act or the 1934 Act,  such number
      of copies of the International  Prospectus (as amended or supplemented) as
      such International  Manager may reasonably  request.  The Prospectuses and
      any  amendments  or  supplements  thereto  furnished to the  International
      Managers  will  be  identical  to the  electronically  transmitted  copies
      thereof filed with the Commission  pursuant to EDGAR, except to the extent
      permitted by Regulation S-T.

            (c)   Continued  Compliance with  Securities  Laws. The Company will
      comply with the 1933 Act and the 1933 Act Regulations and the 1934 Act and
      the rules and  regulations  of the  Commission  thereunder  (the "1934 Act
      Regulations"),  so as to permit the completion of the  distribution of the
      Securities as contemplated in this Agreement,  the U.S. Purchase Agreement
      and in the  Prospectuses.  If at any time when a prospectus is required by
      the 1933 Act to be delivered in connection  with sales of the  Securities,
      any event shall occur or condition  shall exist as a result of which it is
      necessary for the Company to amend the Registration  Statement or amend or
      supplement  the  Prospectuses  in  order  that the  Prospectuses  will not
      include  any  untrue  statements  of a  material  fact or omit to  state a
      material  fact  necessary  in  order to make the  statements  therein  not
      misleading  in the light of the  circumstances  existing at the time it is
      delivered to a purchaser,  or if it shall be necessary at any such time to
      amend the  Registration  Statement or amend or supplement the Prospectuses
      in order to comply with the  requirements  of the 1933 Act or the 1933 Act
      Regulations,   the  Company  will  promptly  prepare  and  file  with  the
      Commission,  such  amendment or  supplement as may be necessary to correct
      such  statement or omission or to make the  Registration  Statement or the
      Prospectuses  comply with such requirements,  and the Company will furnish
      to the  International  Managers such number of copies of such amendment or
      supplement as the International Managers may reasonably request.

            (d)   Rule 158. The Company  will timely file such reports  pursuant
      to the 1934 Act as are necessary in order to make  generally  available to
      its  securityholders  as soon as practicable an earnings statement for the
      purposes  of,  and to  provide  the  benefits  contemplated  by,  the last
      paragraph of Section 11(a) of the 1933 Act.

            (e)   Use of  Proceeds.  The  Company  will  use  the  net  proceeds
      received by it from the sale of the Securities in the manner  specified in
      the Prospectuses under "Use of Proceeds".


                                       12





            (f)    Listing.  The Company will use its best efforts to effect the
      listing of the Securities on the New York Stock Exchange.

            (g)    Restriction  on  Sale  of  Securities.   Subject  to  certain
      exceptions,  including exceptions for the issuance of Common Shares by the
      Company  in  certain  acquisitions  and  transactions   described  in  the
      Prospectuses  under the  heading  "Recent  Developments  - Arbor  Property
      Trust",  during  a  period  of 75 days  from  the  date of the  Prospectus
      Supplements,  the Company will not,  without the prior written  consent of
      the Global Coordinator,  directly or indirectly,  offer, sell, contract to
      sell  or  otherwise  dispose  of  any  Common  Shares  or  any  securities
      convertible  into or exercisable or  exchangeable  for Common Shares.  The
      foregoing  sentence  shall  not  apply  to (A) the  Securities  to be sold
      hereunder  or under the U.S.  Purchase  Agreement,  (B) any Common  Shares
      issued by the  Company  upon the  exercise  of an option or warrant or the
      conversion of a security  outstanding  on the date hereof,  (C) any Common
      Shares  issued or options to purchase  Common Shares  granted  pursuant to
      existing  employee  benefit  plans of the Company,  (D) any Common  Shares
      issued  pursuant  to any  non-employee  director  stock  plan or  dividend
      reinvestment plan or (E) any Common Shares (or securities convertible into
      or exercisable or exchangeable for Common Shares) issued by the Company in
      connection with acquisitions.

      SECTION 4. Payment of Expenses. The Company will pay all expenses incident
to the  performance of its obligations  under this Agreement,  including (i) the
preparation,  printing  and  filing  of the  Registration  Statement  (including
financial  statements  and exhibits) as originally  filed and of each  amendment
thereto,  (ii) the  preparation  and printing of this  Agreement,  any Agreement
among  Underwriters  and such other  documents as may be required in  connection
with the offering, purchase, sale, issuance or delivery of the Securities, (iii)
the preparation, issuance and delivery of the certificates for the Securities to
the  Underwriters,  including any stock or other transfer taxes and any stamp or

the  International  Managers  and the  transfer  of the  Securities  between the
International   Managers   and  the  U.S.   Underwriters,   (iv)  the  fees  and
disbursements of the Company's counsel and accountants,  (v) the  qualification,
if any, of the Securities under state securities laws, including filing fees and
the  reasonable  fees and  disbursements  of  counsel  for the  Underwriters  in
connection  therewith and in  connection  with the  preparation  of any Blue Sky
Survey  and any  supplement  thereto,  (vi) the  printing  and  delivery  to the
Underwriters of copies of each  preliminary  prospectus and of the  Prospectuses
and any  amendments or supplements  thereto,  (vii) the fees and expenses of any

the fees and expenses  incurred in connection with the listing of the Securities
on the New York  Stock  Exchange.  The  Underwriters  will pay all  expenses  in
connection  with the  marketing  of the  Securities,  including  all "road show"
expenses.


                                       13




      Termination  of  Agreement.  If this  Agreement is  terminated by the Lead
Managers  in  accordance  with the  provisions  of Section 5 or Section  9(a)(i)
hereof, the Company shall reimburse the International  Managers for all of their
out-of-pocket  expenses,  including the  reasonable  fees and  disbursements  of
counsel for the International Managers.

      SECTION  5.  Conditions  of  International   Managers'  Obligations.   The
obligations of the several  International  Managers hereunder are subject to the
accuracy of the  representations  and  warranties  of the Company  contained  in
Section  1 hereof  or in  certificates  of any  officer  of the  Company  or any
subsidiary of the Company  delivered  pursuant to the provisions  hereof, to the
performance by the Company of its covenants and other obligations hereunder, and
to the following further conditions:

            (a)    Effectiveness  of  Registration   Statement.  No  stop  order
      suspending the effectiveness of the Registration Statement shall have been
      issued under the 1933 Act or proceedings  therefor initiated or threatened
      by the  Commission,  and any  request  on the part of the  Commission  for

      satisfaction of counsel to the International Managers. The U.S. Prospectus
      shall have been filed with the  Commission  pursuant to Rule 424(b) within

      Time,  the Lead  Managers  shall have  received the  opinion,  dated as of
      Closing  Time,  of Ballard  Spahr  Andrews & Ingersoll,  special  Maryland
      counsel for the Company, in form and substance reasonably  satisfactory to
      counsel for the International Managers, to the effect set forth in Exhibit
      B hereto.

            (d)    Opinion of Counsel  for  International  Managers.  At Closing
      Time, the Lead Managers shall have received the favorable  opinion,  dated

      to the matters set forth in clauses (i), (iii),  (v), (vi) and (xi) in the
      opinion of Sullivan & Cromwell  referred  to in  paragraph  (b) above.  In
      giving such opinion such counsel may rely,  as to all matters  governed by
      the laws of  jurisdictions  other  than the law of the State of New York ,
      the federal law of the United  States and the General  Corporation  Law of
      the State of Delaware,  upon the opinions of counsel  satisfactory  to the
      Lead Managers.  Such counsel may also state that,  insofar as such opinion
      involves  factual  matters,  they have  relied,  to the  extent  they deem
      proper,  upon certificates of officers of the Company and its subsidiaries
      and certificates of public officials.

      been,  since the date  hereof or since  the  respective  dates as of which

      affairs  or  business  prospects  of  the  Company  and  its  subsidiaries
      considered  as one  enterprise,  whether or not  arising  in the  ordinary

      Closing Time, to the effect that they reaffirm the statements  made in the
      letter furnished  pursuant to subsection (f) of this Section,  except that

      business days prior to Closing Time.

            (h)   Approval of Listing.  At Closing Time,  the  Securities  shall

      in Section 2(b) hereof


                                       15




      to purchase all or any portion of the International Option Securities, the
      representations  and  warranties of the Company  contained  herein and the
      statements in any certificates  furnished by the Company or any subsidiary
      of the  Company  hereunder  shall be true and  correct  as of each Date of
      Delivery  and, at the relevant Date of Delivery,  the Lead Managers  shall
      have received:

                (i)   Officers' Certificate.  A certificate,  dated such Date of
            Delivery, of the President or a Vice President of the Company and of
            the Chief  Financial  Officer  of the  Company  confirming  that the
            certificate  delivered at the Closing Time  pursuant to Section 5(e)
            hereof remains true and correct as of such Date of Delivery.

            Delivery and otherwise to the same effect as the opinion required by
            Section 5(d) hereof.

                (iv)  Bring-down   Comfort  Letter.  A  letter  from  Deloitte &

                                       16




             (m)  Termination of Agreement.  If any condition  specified in this
      Section  shall  not  have  been  fulfilled  when  and  as  required  to be
      fulfilled,  this  Agreement,  or,  in the  case  of any  condition  to the
      purchase of International Option Securities on a Date of Delivery which is
      after the Closing  Time,  the  obligations  of the  several  International
      Managers to purchase the relevant Option Securities,  may be terminated by
      the Lead  Managers  by  notice to the  Company  at any time at or prior to
      Closing  Time or such  Date of  Delivery,  as the  case  may be,  and such
      termination  shall be without  liability  of any party to any other  party
      except as  provided  in Section 4 and except  that  Sections 1, 6, 7 and 8
      shall survive any such termination and remain in full force and effect.

      SECTION 6. Indemnification.

             (a) Indemnification of International Managers. The Company and the
      Operating  Partnership  each agree to  indemnify  and hold  harmless  each
      International   Manager  and  each  person,   if  any,  who  controls  any
      International  Manager within the meaning of Section 15 of the 1933 Act or
      Section 20 of the 1934 Act as follows:

                (i)   against  any and all loss,  liability,  claim,  damage and
            expense whatsoever, as incurred, arising out of any untrue statement
            or alleged  untrue  statement  of a material  fact  contained in the
            Registration  Statement (or any amendment thereto),  or the omission
            or alleged  omission  therefrom  of a material  fact  required to be
            stated  therein or  necessary  to make the  statements  therein  not
            misleading or arising out of any untrue  statement or alleged untrue
            statement of a material fact included in any preliminary  prospectus
            or the Prospectuses (or any amendment or supplement thereto), or the
            omission or alleged omission  therefrom of a material fact necessary
            in  order  to make  the  statements  therein,  in the  light  of the
            circumstances under which they were made, not misleading;

                (ii)   against any and all loss,  liability,  claim,  damage and
            expense  whatsoever,  as  incurred,  to the extent of the  aggregate
            amount paid in settlement of any litigation, or any investigation or
            proceeding  by  any  governmental  agency  or  body,   commenced  or
            threatened,  or of any claim  whatsoever  based upon any such untrue
            statement  or  omission,  or any such  alleged  untrue  statement or
            omission;  provided  that  (subject to Section  6(d) below) any such
            settlement is effected with the written consent of the Company; and

               (iii)    against  any and all  expense  whatsoever,  as  incurred
            (including,   subject  to  Section   6(c)   hereof,   the  fees  and
            disbursements  of  counsel  chosen  by  Merrill  Lynch),  reasonably
            incurred  in  investigating,  preparing  or  defending  against  any
            litigation,  or any  investigation or proceeding by any governmental
            agency or body,  commenced or  threatened,  or any claim  whatsoever
            based  upon any  such  untrue  statement  or  omission,  or any such
            alleged  untrue  statement or omission,  to the extent that any such
            expense is not paid under (i) or (ii) above;


                                       17





provided,  however,  that this indemnity  agreement shall not apply to any loss,
liability,  claim,  damage or expense to the  extent  arising  out of any untrue
statement or omission or alleged  untrue  statement or omission made in reliance
upon and in conformity with written information  furnished to the Company by any
International  Manager or U.S. Underwriter through the Lead Managers or the U.S.
Representatives  expressly  for  use  in  the  Registration  Statement  (or  any
amendment  thereto),   or  any  preliminary   prospectus  or  the  International
Prospectus (or any amendment or supplement thereto).

      (b) Indemnification of Company, Operating Partnership,  Trustees, Partners
and Officers.  Each International Manager severally agrees to indemnify and hold
harmless the Company,  the Operating  Partnership,  their respective trustees or
partners, each of the officers who signed the Registration  Statement,  and each
person, if any, who controls the Company or the Operating Partnership within the
meaning of Section 15 of the 1933 Act or Section 20 of the 1934 Act  against any
and all loss,  liability,  claim,  damage and expense described in the indemnity
contained in subsection (a) of this Section, as incurred,  but only with respect
to untrue  statements or omissions,  or alleged untrue  statements or omissions,
made  in  the  Registration   Statement  (or  any  amendment  thereto),  or  any
preliminary  prospectus  or  the  International  Prospectus  (or  any  amendment
thereto) in reliance upon and in conformity with written  information  furnished
to the Company by such International Manager through the Lead Managers expressly
for  use in the  Registration  Statement  (or  any  amendment  thereto)  or such
preliminary  prospectus  or  the  International  Prospectus  (or  any  amendment
thereto).

      (c) Actions against Parties;  Notification.  Each indemnified  party shall
give notice as promptly as reasonably  practicable to each indemnifying party of
any action  commenced  against it in  respect of which  indemnity  may be sought
hereunder, but failure to so notify an indemnifying party shall not relieve such
indemnifying  party  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.  In the case of parties  indemnified  pursuant to Section 6(a) above,
counsel to the indemnified  parties shall be selected by Merrill Lynch,  and, in
the case of parties indemnified  pursuant to Section 6(b) above,  counsel to the
indemnified  parties shall be selected by the Company. An indemnifying party may
participate  at its own  expense in the  defense of any such  action;  provided,
however,  that  counsel to the  indemnifying  party shall not  (except  with the
consent of the indemnified  party) also be counsel to the indemnified  party. In
no event shall the indemnifying  parties be liable for fees and expenses of more
than one counsel  (in  addition to any local  counsel)  separate  from their own
counsel  for all  indemnified  parties  in  connection  with any one  action  or
separate but similar or related actions in the same jurisdiction  arising out of
the same general  allegations or  circumstances.  No  indemnifying  party shall,
without  the  prior  written  consent  of the  indemnified  parties,  settle  or
compromise  or  consent  to  the  entry  of any  judgment  with  respect  to any
litigation,  or any  investigation or proceeding by any  governmental  agency or
body,  commenced  or  threatened,  or any claim  whatsoever  in respect of which
indemnification  or contribution could be sought under this Section 6 or Section
7 hereof (whether or not the indemnified parties are actual or potential parties
thereto),  unless  such  settlement,  compromise  or  consent  (i)  includes  an
unconditional  release of each indemnified  party from all 

                                       18




liability arising out of such litigation, investigation, proceeding or claim and
(ii) 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.


      (d) Settlement without Consent if Failure to Reimburse.  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 6(a)(ii)  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, (iii) such indemnifying party, if it has not theretofore paid such
reimbursement,  is requested again to pay  reimbursement  at least five, but not
more than ten, days prior to such  settlement  being entered into, and (iv) such
indemnifying   party  shall  not  have  reimbursed  such  indemnified  party  in
accordance with such request prior to the date of such settlement.

      SECTION 7. Contribution.  If the indemnification provided for in Section 6
hereof is for any reason  unavailable  to or  insufficient  to hold  harmless an
indemnified  party in respect of any  losses,  liabilities,  claims,  damages or
expenses referred to therein,  then each indemnifying  party shall contribute to
the aggregate amount of such losses,  liabilities,  claims, damages and expenses
incurred by such  indemnified  party, as incurred,  (i) in such proportion as is
appropriate to reflect the relative  benefits received by the Company on the one
hand and the  International  Managers on the other hand from the offering of the
Securities  pursuant to this  Agreement  or (ii) if the  allocation  provided by
clause  (i) is not  permitted  by  applicable  law,  in  such  proportion  as is
appropriate to reflect not only the relative  benefits referred to in clause (i)
above  but also the  relative  fault of the  Company  on the one hand and of the
International  Managers on the other hand in connection  with the  statements or
omissions  which  resulted  in such  losses,  liabilities,  claims,  damages  or
expenses, as well as any other relevant equitable considerations.

      The  relative  benefits  received  by the  Company on the one hand and the
International  Managers on the other hand in connection with the offering of the
International Securities pursuant to this Agreement shall be deemed to be in the
same  respective  proportions as the total net proceeds from the offering of the
International  Securities pursuant to this Agreement (before deducting expenses)
received  by the  Company and the total  underwriting  discount  received by the
International  Managers,  in  each  case  as  set  forth  on  the  cover  of the
International Prospectus, bear to the aggregate initial public offering price of
the International Securities as set forth on such cover.

      The  relative  fault of the Company on the one hand and the  International
Managers on the other hand shall be  determined  by  reference  to,  among other
things,  whether any such untrue or alleged untrue  statement of a material fact
or omission or alleged  omission to state a material fact relates to information
supplied  by the  Company  or by the  International  Managers  and the  parties'
relative intent, knowledge,  access to information and opportunity to correct or
prevent such statement or omission.


                                       19



      The Company and the International Managers agree that it would not be just
and equitable if contribution  pursuant to this Section 7 were determined by pro
rata allocation (even if the  International  Managers were treated as one entity
for such  purpose)  or by any other  method of  allocation  which  does not take
account of the equitable considerations referred to above in this Section 7. The
aggregate amount of losses,  liabilities,  claims, damages and expenses incurred
by an indemnified  party and referred to above in this Section 7 shall be deemed
to include any legal or other expenses  reasonably  incurred by such indemnified
party in investigating,  preparing or defending  against any litigation,  or any
investigation  or proceeding by any  governmental  agency or body,  commenced or
threatened, or any claim whatsoever based upon any such untrue or alleged untrue
statement or omission or alleged omission.

      Notwithstanding the provisions of this Section 7, no International Manager
shall be required to contribute  any amount in excess of the amount by which the
total  price  at  which  the  International  Securities  underwritten  by it and
distributed  to the public were offered to the public  exceeds the amount of any
damages which such  International  Manager has otherwise been required to pay by
reason of any 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 1933 Act) shall be entitled to contribution from any person
who was not guilty of such fraudulent misrepresentation.

      For  purposes of this  Section 7, each  person,  if any,  who  controls an
International  Manager  within  the  meaning  of  Section  15 of the 1933 Act or
Section 20 of the 1934 Act shall have the same  rights to  contribution  as such
International  Manager,  and each trustee or partner, as the case may be, of the
Company or the Operating  Partnership,  each officer who signed the Registration
Statement,  and each person, if any, who controls the Company within the meaning
of  Section 15 of the 1933 Act or Section 20 of the 1934 Act shall have the same
rights to contribution as the Company or the Operating Partnership,  as the case
may  be.  The  International  Managers'  respective  obligations  to  contribute
pursuant to this  Section 7 are several in  proportion  to the number of Initial
International Securities set forth opposite their respective names in Schedule A
hereto and not joint.

      SECTION 8. Representations, Warranties and Agreements to Survive Delivery.
All representations, warranties and agreements contained in this Agreement or in
certificates  of officers of the  Company or any of its  subsidiaries  submitted
pursuant hereto, shall remain operative and in full force and effect, regardless
of any  investigation  made by or on  behalf  of any  International  Manager  or
controlling  person,  or by or on  behalf  of the  Company,  and  shall  survive
delivery of the Securities to the International Managers.

      SECTION 9. Termination of Agreement.

      (a) Termination;  General. The Lead Managers may terminate this Agreement,
by notice to the  Company,  at any time at or prior to Closing Time (i) if there
has been,  since the 


                                       20





time of execution of this  Agreement or since the  respective  dates as of which
information  is given in the  International  Prospectus,  any  material  adverse
change in the condition,  financial or otherwise,  or in the earnings,  business
affairs or business prospects of the Company and its subsidiaries  considered as
one enterprise,  whether or not arising in the ordinary  course of business,  or
(ii) if there has occurred any material adverse change in the financial  markets
in the United States or the  international  financial  markets,  any outbreak of
hostilities  or escalation  thereof or other calamity or crisis or any change or
development   involving  a  prospective  change  in  national  or  international
political, financial or economic conditions, in each case the effect of which is
such as to make it,  in the  judgment  of the Lead  Managers,  impracticable  to
market the Securities or to enforce contracts for the sale of the Securities, or
(iii)  if  trading  in any  securities  of the  Company  has been  suspended  or
materially  limited  by the  Commission  or the New York Stock  Exchange,  or if
trading  generally on the American Stock Exchange or the New York Stock Exchange
or in the Nasdaq  National Market has been suspended or materially  limited,  or
minimum or maximum  prices for trading  have been fixed,  or maximum  ranges for
prices  have been  required,  by any of said  exchanges  or by such system or by
order of the Commission, the National Association of Securities Dealers, Inc. or
any  other  governmental  authority,  or (iv) if a banking  moratorium  has been
declared by either Federal or New York authorities.

      (b) Liabilities. If this Agreement is terminated pursuant to this Section,
such  termination  shall be without  liability  of any party to any other  party
except as provided in Section 4 hereof, and provided further that Sections 1, 6,
7 and 8 shall survive such termination and remain in full force and effect.

      SECTION 10. Default by One or More of the International  Managers.  If one
or more of the  International  Managers  shall fail at Closing Time or a Date of
Delivery to purchase the  Securities  which it or they are obligated to purchase
under this Agreement (the "Defaulted Securities"),  the Lead Managers shall have
the right,  within 24 hours thereafter,  to make arrangements for one or more of
the  non-defaulting  International  Managers,  or  any  other  underwriters,  to
purchase all, but not less than all, of the Defaulted Securities in such amounts
as may be agreed upon and upon the terms herein set forth; if, however, the Lead
Managers shall not have completed such arrangements  within such 24-hour period,
then:

            (a)   if the number of Defaulted  Securities  does not exceed 10% of
      the aggregate  number of  Securities to be purchased by the  International
      Managers and the U.S.  Managers on such date,  each of the  non-defaulting
      International  Managers shall be obligated,  severally and not jointly, to
      purchase the full amount thereof in the proportions  that their respective
      underwriting obligations hereunder bear to the underwriting obligations of
      all non-defaulting International Managers, or

            (b)   if the  number  of  Defaulted  Securities  exceeds  10% of the
      aggregate  number  of  Securities  to be  purchased  by the  International
      Managers or the U.S.  Underwriters  on such date,  this Agreement or, with
      respect to any Date of Delivery  which occurs after the Closing Time,  the
      obligation of the International Managers to purchase and of the Company to
      sell the International  Option Securities to be purchased 


                                       21





      and sold on such Date of Delivery,  shall terminate  without  liability on
      the part of any non-defaulting International Manager.

      No action taken  pursuant to this  Section  shall  relieve any  defaulting
International Manager from liability in respect of its default.

      In the event of any such default which does not result in a termination of

                      FORM OF OPINIONS OF COMPANY'S COUNSEL
                           TO BE DELIVERED PURSUANT TO
                                  SECTION 5(b)


          (i)     The Company is a real estate  investment  trust duly organized
and  existing  under the laws of the State of Maryland  and is in good  standing
with the State Department of Assessments and Taxation of Maryland;

         (ii)     The Company has the  trust power and  authority to own,  lease
and operate its properties and conduct its business  substantially  as described
in the  Prospectuses  and the Company has the trust power and authority to enter
into and perform its obligations under this Agreement;

        (iii)      The issuance and sale of the International Securities to  the

issued, fully paid and nonassessable;

         (iv)      Such counsel does not know of any litigation or  governmental
proceedings  instituted  or  threatened  against  the  Company  or  any  of  its
subsidiaries  that would be required to be disclosed in the  Prospectuses and is
not so  disclosed;  and such  counsel  does not know of any  documents  that are
required to be filed as exhibits to the  Registration  Statement  and are not so
filed or of any documents that are required to be summarized in the Prospectuses
that are not so summarized;

          (v)      This  Agreement  has  been  duly  authorized,   executed  and
delivered by the Company;

         (vi)      The Registration  Statement has been declared effective under
the Act,  and, to the best of such counsel's knowledge, no stop order suspending
the  effectiveness  of  the  Registration  Statement  has  been  issued  and  no
proceedings for that purpose have been  instituted or are pending under the 1933
Act; and

        (vii)      All  regulatory  consents,  authorizations,  approvals    and
filings required to be obtained or made by the Company under the Federal laws of
the United States and the laws of the State of New York for the  issuance,  sale
and delivery of the International Securities by the Company to the International
Managers have been  obtained or made;  provided,  however,  that for purposes of
this paragraph (vii),  such counsel need not express any opinion with respect to
state securities laws;







       (viii)      The execution and delivery by the Company of  this  Agreement
does not, and the issuance of the  International  Securities and the sale of the
International   Securities  to  the  International  Managers  pursuant  to  this
Agreement  and the  performance  by the  Company of its  obligations  under this
Agreement and the consummation of the transactions  herein contemplated will not
(A) violate the Company's Amended and Restated Declaration of Trust or Bylaws or
the  certificate  or  articles  of  incorporation  or  by-laws  of  any  of  its
subsidiaries, (B) violate any court order or administrative decree known to such
counsel or any federal law of the United  States or law of the State of New York
applicable  to the  Company,  or (C) result in a default  under or breach of any
contract,  indenture,  mortgage, loan agreement, note, lease or other instrument
filed as an  exhibit  to the  Registration  Statement  or as an  exhibit  to any
current document  incorporated by reference  therein to which the Company or any
subsidiary  is a party or by which any of them may be bound,  or to which any of
their property is subject,  subject,  in the case of clauses (A), (B) and (C) of
this  paragraph  (viii),  to  bankruptcy,   insolvency,   fraudulent   transfer,
reorganization, moratorium and similar laws of general applicability relating to
or  affecting  creditors'  rights and to general  equity  principles;  provided,
however,  that for  purposes of this  paragraph  (viii),  such  counsel need not
express any opinion  with  respect to federal or state  securities  laws,  other
antifraud laws or fraudulent transfer laws;

         (ix)      The  information  set  forth in the  Prospectuses  under  the
heading  "Certain  Federal  Income  Tax  Considerations",  and under  such other
heading in the  Prospectuses,  as amended or  supplemented  with  respect to the
International  Securities,  describing the tax considerations in connection with
the International  Securities,  to the extent that it constitutes matters of law
or legal conclusions,  is correct in all material  respects;  provided that such
opinion may be rendered in reliance upon  representations  made by third parties
and, as to the  qualification of Alexander's,  Inc. as a real estate  investment
trust for federal income tax purposes, an opinion of Shearman & Sterling;

          (x)      Neither  the  Company  nor  any  of  its  subsidiaries  is an
"investment  company" or an entity "controlled" by an "investment  company",  as
such terms are defined in the Investment Company Act of 1940;

         (xi)      On the basis of the  information  which was  reviewed  in the
course  of  the  performance  of  the  services  referred  to in  their  opinion
considered in the light of their  understanding of the applicable law (including
the  requirements  of Form S-3 and the character of the prospectus  contemplated
thereby) and the  experience  they have gained  through their practice under the
1933 Act, such counsel are of the opinion that the Registration Statement, as of
its effective date, and the  Prospectuses,  as of the date of the  Prospectuses,
appeared on their face to be appropriately  responsive in all material  respects
to the  requirements  of the 1933 Act and the  1933  Act  Regulations;  and that
nothing  that came to their  attention  in the course of their review has caused
them to believe  that the  Registration  Statement,  as of its  effective  date,
contained  any  untrue  statement  of a  material  fact or  omitted to state any
material fact required to be stated 







therein or necessary to make the  statements  therein not misleading or that the
Prospectuses,  as of their date,  contained  any untrue  statement of a material
fact or  omitted  to state  any  material  fact  necessary  in order to make the
statements  therein,  in the light of the  circumstances  under  which they were
made, not misleading; also, nothing that has come to such counsel's attention in
the course of certain  procedures (as described in such opinion) has caused such
counsel to believe that the Prospectuses, as of the date and time of delivery of
such opinion,  contained  any untrue  statement of a material fact or omitted to
state any material fact  necessary in order to make the statements  therein,  in
the light of the  circumstances  under  which  they were made,  not  misleading;
provided,  however, that such opinion may state that the limitations inherent in
the   independent   verification   of  factual  matters  and  the  character  of
determinations  involved in the registration  process are such that such counsel
do not assume any responsibility  for the accuracy,  completeness or fairness of
the  statements  contained in the  Registration  Statement or the  Prospectuses,
except as  otherwise  specifically  referred to in  paragraph  (viii)  above and
except for those made under the heading  "Description  of Common  Shares" in the
Prospectuses  insofar as they  relate to the  provisions  of  documents  therein
described,  and that such  counsel  need not express any opinion or belief as to
the financial  statements and schedules or other financial data contained in the
Registration Statement or the Prospectuses.

      In giving  these  opinions,  Sullivan &  Cromwell  may state that they are
admitted  to the bar of the State of New York and do not  express any opinion as
to the laws of any other  jurisdiction other than the federal laws of the United
States of America and may rely (1) as to all matters of fact, upon  certificates
and written  statements  of officers and  employees of and  accountants  for the
Company and (2) as to all matters of Maryland  law,  upon the opinion of Ballard
Spahr Andrews & Ingersoll and certificates of appropriate government officials.
