Item 5.        Other Events.

         On October 14, 1997, Vornado Realty Trust (the "Company") filed with
the Maryland Department of Assessments and Taxation an amendment to the
Company's Amended and Restated Declaration of Trust (the "Declaration of Trust")
to increase the Company's authorized share capital. As so amended, the
Declaration of Trust authorizes the issuance of up to 240,000,000 shares of
beneficial interest, consisting of 100,000,000 common shares of beneficial
interest, par value $0.04 per share, 20,000,000 preferred shares of beneficial
interest, no par value per share, and 120,000,000 excess shares of beneficial
interest.

         On October 21, 1997, the Company and Vornado Realty L.P. entered into a
U.S. Purchase Agreement with Merrill Lynch, Pierce, Fenner & Smith Incorporated,
Goldman, Sachs & Co., Furman Selz LLC, Salomon Brothers Inc, Smith Barney Inc.
and UBS Securities LLC, as U.S. representatives of the several U.S. Underwriters
named therein, and an International Purchase Agreement with Merrill Lynch
International, Goldman Sachs International, Furman Selz LLC, Salomon Brothers
International Limited, Smith Barney Inc. and UBS Limited, relating to the
issuance and sale by the Company of an aggregate of 14 million common shares of
beneficial interest, par value $0.04 per share (the "Common Shares"), of the
Company (the "Firm Securities"), plus up to an additional 2,100,000 Common
Shares, the issuance and sale of which is subject to the exercise of the
underwriters' over-allotment options (the "Additional Securities" and, together
with the Firm Securities, the "Offered Securities"), at a public offering price
of $45.00 per share. The underwriting discount under the Purchase Agreements is
$2.14 per share. The Purchase Agreements also provide for the underwriters' per
share purchase price for any Additional Securities to be reduced by an amount
equal to any dividends or distributions declared by the Company and payable on
the Firm Securities but not on the Additional Securities.

Ladies and Gentlemen:

      Vornado  Realty  Trust,  a  Maryland  real  estate  investment  trust (the
"Company"),  confirms its  agreement  with Merrill Lynch & Co.,  Merrill  Lynch,
Pierce, Fenner & Smith Incorporated ("Merrill Lynch") and each of the other U.S.
Underwriters named in Schedule A hereto (collectively,  the "U.S. Underwriters",
which  term  shall also  include  any  underwriter  substituted  as  hereinafter
provided in Section 10 hereof),  for whom Merrill Lynch,  Goldman,  Sachs & Co.,
Furman Selz LLC,  Salomon Brothers Inc, Smith Barney Inc. and UBS Securities LLC
are acting as representatives  (in such capacity,  the "U.S.  Representatives"),
with  respect to the issue and sale by the Company and the  purchase by the U.S.
Underwriters,  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 U.S.  Underwriters,  acting severally and not jointly, of the
option


                                        1

<PAGE>



described  in  Section  2(b)  hereof to  purchase  all or any part of  1,680,000
additional  Common  Shares  to  cover  over-allotments,  if any.  The  aforesaid
11,200,000 Common Shares (the "Initial U.S.  Securities") to be purchased by the
U.S.  Underwriters and all or any part of the 1,680,000 Common Shares subject to
the option described in Section 2(b) hereof (the "U.S.  Option  Securities") are
hereinafter called, collectively, the "U.S. Securities".

      It is  understood  that  the  Company  is  concurrently  entering  into an
agreement  dated  the  date  hereof  (the  "International  Purchase  Agreement")
providing  for the offering by the Company of an  aggregate of 2,800,000  Common
Shares  (the  "Initial  International  Securities")  through  arrangements  with
certain  underwriters  outside the United States and Canada (the  "International
Managers") for which Merrill Lynch  International,  Goldman Sachs International,
Furman Selz LLC,  Salomon  Brothers  International,  Smith  Barney Inc.  and UBS
Limited are acting as lead managers (the "Lead  Managers")  and the grant by the
Company to the International  Managers,  acting severally and not jointly, of an
option to purchase  all or any part of up to 420,000  additional  Common  Shares
solely to cover  overallotments,  if any (the "International  Option Securities"
and, together with the U.S. Option  Securities,  the "Option  Securities").  The
Initial  International  Securities and the  International  Option Securities are
hereinafter  called the  "International  Securities".  It is understood that the
Company is not obligated to sell and the U.S.  Underwriters are not obligated to
purchase,  any Initial U.S.  Securities unless all of the Initial  International
Securities are contemporaneously purchased by the International Managers.

      The U.S.  Underwriters  and the  International  Managers  are  hereinafter
collectively  called the  "Underwriters",  the Initial U.S.  Securities  and the
Initial  International   Securities  are  hereinafter  collectively  called  the
"Initial Securities",  and the U.S. Securities and the International  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 U.S.  Underwriters  propose  to make a
public offering of the U.S. Securities as soon as the U.S.  Representatives 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 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 paragraph  (b) of Rule 424 ("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


                                        2

<PAGE>



after the date hereof pursuant to Rule 424(b),  is hereinafter  called the "U.S.
Prospectus Supplement." Concurrently with the preparation and filing of the U.S.
Prospectus  Supplement,  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,  in the form first distributed after the date hereof, is hereinafter
called the "International Prospectus Supplement." The U.S. Prospectus Supplement
and the International  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 U.S.  Prospectus  Supplement is
hereinafter   called  the  "U.S.   Prospectus"   and  as   supplemented  by  the
International  Prospectus  Supplement is hereinafter  called the  "International
Prospectus"  and the  U.S.  Prospectus  and  the  International  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 U.S.
Prospectus  Supplement  is  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.

      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,

      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,

      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

      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

      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

      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:

                    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

              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 re lease, 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 subsidiaries, whether by contract or law; and

                    C. the Company and its subsidiaries  have fully disclosed to
              the U.S.  Underwriters  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 U.S.
Representatives  or to  counsel  for the U.S.  Underwriters  shall  be  deemed a
representation  and warranty by the Company to each U.S.  Underwriter  as to the

      (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 U.S. Underwriter,  severally and not jointly, and
each U.S.  Underwriter,  severally and not jointly,  agrees to purchase from the
Company,  at the price per share set forth in  Schedule B, the number of Initial
U.S.  Securities  set  forth  in  Schedule  A  opposite  the  name of such  U.S.

Underwriter,  plus any additional  number of Initial U.S.  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 U.S.  Underwriters,
severally  and not jointly,  to purchase up to an  additional  1,680,000  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 U.S.  Securities but not payable on the U.S. 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  U.S.   Securities  upon  notice  by  the  Global
Coordinator to the Company setting forth the number of U.S. Option Securities as
to which the several U.S.  Underwriters  are then  exercising the option and the
time and date of payment and delivery for such U.S. Option Securities.  Any such
time and date of delivery for the U.S. 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 U.S.  Option  Securities,  each of the U.S.  Underwriters,
acting  severally and not jointly,  will  purchase that  proportion of the total
number of U.S.  Option  Securities  then  being  purchased  which the  number of
Initial U.S.  Securities  set forth in Schedule A opposite the name of such U.S.
Underwriter  bears to the total  number of Initial U.S.  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 U.S.  Option  Securities
are purchased by the U.S.  Underwriters,  payment of the purchase price for, and
delivery of certificates  for, such U.S. 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.

      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

purchased by them. It is understood  that each U.S.  Underwriter  has authorized
the U.S.  Representatives,  for its account, to accept delivery of, receipt for,
and make payment of the purchase price for, the Initial U.S.  Securities and the
U.S. Option Securities, if any, which it has agreed to purchase.  Merrill Lynch,
individually and not as representative of the U.S. Underwriters,  may (but shall
not be obligated  to) make  payment of the  purchase  price for the Initial U.S.
Securities or the U.S.  Option  Securities,  if any, to be purchased by any U.S.
Underwriter  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 U.S. Underwriter from its obligations hereunder.

      (d)  Denominations;   Registration.  Certificates  for  the  Initial  U.S.
Securities  and  the  U.S.  Option   Securities,   if  any,  shall  be  in  such
denominations  and  registered  in such  names as the U.S.  Representatives  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
U.S.  Securities and the U.S. Option Securities,  if any, will be made available
for  examination  and packaging by the U.S.  Representatives  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 U.S.
Underwriter as follows:

              (a) Delivery of Registration Statements. The Company has furnished
      or will  deliver  to the U.S.  Representatives  and  counsel  for the U.S.
      Underwriters,  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 U.S.
      Representatives,  without  charge,  a conformed  copy of the  Registration
      Statement  as  originally  filed and of each  amendment  thereto  (without
      exhibits)  for  each  of  the  U.S.   Underwriters.   The  copies  of  the
      Registration  Statement and each amendment  thereto  furnished to the U.S.
      Underwriters 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 U.S. Prospectus is required by the
      1933 Act to be delivered in connection with sales of the U.S.  Securities,
      the Company will inform the U.S.  Representatives of its intention to file
      any amendment to the Registration  Statement or any supplement to the U.S.
      Prospectus;  will furnish the U.S. Representatives 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 U.S.
      Representatives  or counsel  for the U.S.  Underwriters  shall  reasonably
      object (it being understood that the terms "amendment" and "supplement" do
      not include documents filed by the Company pursuant to the 1934 Act).



                                       11

<PAGE>



              (b) Delivery of  Prospectuses.  The Company has  delivered to each
      U.S.  Underwriter,  without  charge,  as many  copies of each  preliminary
      prospectus as such U.S. Underwriter 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 U.S.  Underwriter,  without
      charge,  during the period  when the U.S.  Prospectus  is  required  to be
      delivered under the 1933 Act or the 1934 Act, such number of copies of the
      U.S. Prospectus (as amended or supplemented) as such U.S.  Underwriter may
      reasonably  request.  The  Prospectuses  and any amendments or supplements
      thereto  furnished  to the  U.S.  Underwriters  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 International  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 U.S.  Underwriters  such  number  of copies  of such  amendment  or
      supplement as the U.S. Underwriters 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".

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

      convertible  into or exercisable or  exchangeable  for Common Shares.  The

              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;

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
U.S.  Underwriter or International  Manager through the U.S.  Representatives or
the  Lead  Managers  expressly  for use in the  Registration  Statement  (or any


                                       17

amendment thereto), or any preliminary prospectus or the U.S. Prospectus (or any
amendment or supplement thereto).

      (b) Indemnification of Company, Operating Partnership,  Trustees, Partners
and  Officers.  Each U.S.  Underwriter  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 U.S.  Prospectus  (or any  amendment  thereto) in
reliance  upon and in  conformity  with  written  information  furnished  to the
Company by such U.S. Underwriter through the U.S. Representatives  expressly for
use in the Registration Statement (or any amendment thereto) or such preliminary
prospectus or the U.S. 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 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.


                                       18

<PAGE>



      (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 U.S.  Underwriters  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 U.S.
Underwriters  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 U.S.
Underwriters  on the other  hand in  connection  with the  offering  of the U.S.
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 U.S.
Securities  pursuant to this Agreement (before deducting  expenses)  received by
the  Company  and  the  total   underwriting   discount  received  by  the  U.S.
Underwriters,  in each case as set  forth on the  cover of the U.S.  Prospectus,
bear to the aggregate  initial public  offering price of the U.S.  Securities as
set forth on such cover.

      The  relative  fault  of  the  Company  on  the  one  hand  and  the  U.S.
Underwriters  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 U.S.  Underwriters  and the parties'  relative
intent,  knowledge,  access to information and opportunity to correct or prevent
such statement or omission.

      The Company and the U.S.  Underwriters 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 U.S.  Underwriters  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.


                                       19

<PAGE>


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 U.S.  Underwriter
shall be required to contribute  any amount in excess of the amount by which the
total price at which the U.S.  Securities  underwritten by it and distributed to
the public were  offered to the public  exceeds the amount of any damages  which
such U.S.  Underwriter  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 a U.S.
Underwriter  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  U.S.
Underwriter,  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 U.S.  Underwriters'  respective  obligations to contribute  pursuant to this
Section 7 are several in proportion to the number of Initial U.S. 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 U.S. Underwriter or controlling
person,  or by or on behalf of the Company,  and shall  survive  delivery of the
Securities to the U.S. Underwriters.

      SECTION 9. Termination of Agreement.
                 ------------------------

      (a)  Termination;  General.  The U.S.  Representatives  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 time of execution  of this  Agreement or since the
respective dates as of which  information is given in the U.S.  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  


                                       20

<PAGE>



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 U.S.  Representatives,  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 U.S.  Underwriters.  If one or
more of the U.S.  Underwriters  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 U.S. Representatives shall have the
right,  within 24 hours thereafter,  to make arrangements for one or more of the
non-defaulting U.S.  Underwriters,  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 U.S.
Representatives  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  U.S.
      Underwriters  and the  International  Managers  on such date,  each of the
      non-defaulting  U.S.  Underwriters  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 U.S. Underwriters, or

              (b) if the  number  of  Defaulted  Securities  exceeds  10% of the
      aggregate  number of Securities  to be purchased by the U.S.  Underwriters
      and the  International  Managers  on such date,  this  Agreement  or, with
      respect to any Date of Delivery  which occurs after the Closing Time,  the
      obligation of the U.S. Underwriters to purchase and of the Company to sell
      the U.S.  Option  Securities  to be  purchased  and  sold on such  Date of
      Delivery,   shall  terminate   without   liability  on  the  part  of  any
      non-defaulting U.S. Underwriter.



                                       21

<PAGE>



      No action taken pursuant to this Section shall relieve any defaulting U.S.
Underwriter from liability in respect of its default.

      In the event of any such default which does not result in a termination of
this  Agreement or, in the case of a Date of Delivery which is after the Closing
Time,  which  does not result in a  termination  of the  obligation  of the U.S.
Underwriters  to  purchase  and the  Company to sell the  relevant  U.S.  Option
Securities,  as the case may be, either the U.S.  Representatives or the Company
shall have the right to postpone  Closing Time or the relevant Date of Delivery,
as the case may be, for a period not exceeding seven days in order to effect any
required changes in the  Registration  Statement or Prospectuses or in any other
documents or arrangements.  As used herein, the term "U.S. Underwriter" includes
any person substituted for a U.S. Underwriter under this Section 10.

      SECTION 11. Notices. All notices and other communications  hereunder shall
be in  writing  and  shall be  deemed  to have  been  duly  given if  mailed  or
transmitted  by any  standard  form of  telecommunication.  Notices  to the U.S.
Underwriters shall be directed to the U.S.  Representatives  c/o Merrill Lynch &
Co. at North Tower,  World  Financial  Center,  New York,  New York  10281-1201,
attention of Richard  Saltzman;  and notices to the Company shall be directed to
it at Park  80  West,  Plaza  II,  Saddle  Brook,  NJ  07663,  attention  of the
Secretary.

      SECTION 12. Parties. This Agreement shall each inure to the benefit of and
be binding upon the U.S.  Underwriters,  the Company, the Operating  Partnership
and  their  respective  successors.  Nothing  expressed  or  mentioned  in  this
Agreement  is  intended  or  shall be  construed  to give  any  person,  firm or
corporation,  other  than  the  U.S.  Underwriters  and the  Company  and  their
respective  successors and the  controlling  persons and officers,  trustees and
partners   referred   to  in  Sections  6  and  7  and  their  heirs  and  legal
representatives,  any legal or  equitable  right,  remedy  or claim  under or in
respect of this Agreement or any provision herein contained.  This Agreement and
all  conditions  and  provisions  hereof  are  intended  to be for the  sole and
exclusive benefit of the U.S.  Underwriters and the Company and their respective
successors, and said controlling persons and officers, trustees and partners and
their heirs and legal  representatives,  and for the benefit of no other person,
firm or corporation.  No purchaser of Securities from any U.S. Underwriter shall
be deemed to be a successor by reason merely of such purchase.

      SECTION 13.  GOVERNING LAW AND TIME.  THIS AGREEMENT  SHALL BE GOVERNED BY
AND  CONSTRUED IN ACCORDANCE  WITH THE LAWS OF THE STATE OF NEW YORK.  SPECIFIED
TIMES OF DAY REFER TO NEW YORK CITY TIME.

      SECTION 14. Effect of Headings.  The Article and Section  headings  herein
and the Table of  Contents  are for  convenience  only and shall not  affect the
construction hereof.

      payment  pursuant to this Agreement,  the U.S.  Securities will be validly
      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

      that are  required to be filed as exhibits to the  Registration  Statement

      summarized in the Prospectuses that are not so summarized;

           (viii)   The execution and delivery by the Company of this  Agreement
      does not, and the issuance of the U.S. Securities and the sale of the U.S.
      Securities  to the U.S.  Underwriters  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 U.S. Securities,  describing the tax considerations in connection with
      the U.S.  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


                                       A-2

<PAGE>



      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.

International  Managers are not obligated to purchase, any Initial International

"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

"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

          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

      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

<PAGE>


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
<PAGE>


      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
<PAGE>


      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".

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

      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.

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

      suspending the effectiveness of the Registration Statement shall have been

            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 &
            Touche LLP, in form and substance  satisfactory to the Lead Managers
            and dated such Date of Delivery,  substantially in the same form and
            substance as the letter  furnished to the Lead Managers  pursuant to
            Section 5(g) hereof,  except that the "specified date" in the letter
            furnished  pursuant to this paragraph  shall be a date not more than
            five days prior to such Date of Delivery.

             (l)   Additional  Documents.  At  Closing  Time and at each Date of
      Delivery, counsel for the International Managers shall have been furnished
      with such  documents  and  opinions as they may require for the purpose of
      enabling  them to pass upon the  issuance  and sale of the  Securities  as
      herein  contemplated,  or in order to evidence  the accuracy of any of the
      representations   or  warranties,   or  the  fulfillment  of  any  of  the
      conditions,  herein contained; and all proceedings taken by the Company in

      contemplated shall be reasonably satisfactory in form and substance to the
      Lead Managers and counsel for the International Managers.

             (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

<PAGE>



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

<PAGE>


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
<PAGE>


      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

<PAGE>



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

<PAGE>



      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
this  Agreement or, in the case of a Date of Delivery which is after the Closing
Time,  which  does  not  result  in a  termination  of  the  obligation  of  the
International  Managers  to  purchase  and  the  Company  to sell  the  relevant
International Option Securities, as the case may be, either the Lead Managers or
the Company  shall have the right to postpone  Closing Time or the relevant Date
of Delivery,  as the case may be, for a period not exceeding seven days in order
to effect any required changes in the Registration  Statement or Prospectuses or
in any other documents or arrangements.  As used herein, the term "International
Manager" includes any person substituted for a International  Manager under this
Section 10.

      SECTION 11. Notices. All notices and other communications  hereunder shall
be in  writing  and  shall be  deemed  to have  been  duly  given if  mailed  or
transmitted  by  any  standard  form  of   telecommunication.   Notices  to  the
International  Managers shall be directed to the Lead Managers c/o Merrill Lynch
International at Ropemaker Place, 25 Ropemaker Street, London EC2Y 9LY, England,
attention of Richard  Saltzman;  and notices to the Company shall be directed to
it at Park  80  West,  Plaza  II,  Saddle  Brook,  NJ  07663,  attention  of the
Secretary.

      SECTION 12. Parties. This Agreement shall each inure to the benefit of and
be  binding  upon  the  International   Managers,  the  Company,  the  Operating
Partnership and their respective  successors.  Nothing expressed or mentioned in
this  Agreement is intended or shall be  construed  to give any person,  firm or
corporation,  other than the  International  Managers  and the Company and their
respective  successors and the  controlling  persons and officers,  trustees and
partners   referred   to  in  Sections  6  and  7  and  their  heirs  and  legal
representatives,  any legal or  equitable  right,  remedy  or claim  under or in
respect of this Agreement or any provision herein contained.  This Agreement and
all  conditions  and  provisions  hereof  are  intended  to be for the  sole and
exclusive  benefit  of the  International  Managers  and the  Company  and their
respective successors,  and said controlling persons and officers,  trustees and
partners  and their heirs and legal  representatives,  and for the benefit of no
other  person,  firm  or  corporation.  No  purchaser  of  Securities  from  any
International Manager shall be deemed to be a successor by reason merely of such
purchase.

      SECTION 13.  GOVERNING LAW AND TIME.  THIS AGREEMENT  SHALL BE GOVERNED BY
AND  CONSTRUED IN ACCORDANCE  WITH THE LAWS OF THE STATE OF NEW YORK.  SPECIFIED
TIMES OF DAY REFER TO NEW YORK CITY TIME.

      SECTION 14. Effect of Headings.  The Article and Section  headings  herein
and the Table of  Contents  are for  convenience  only and shall not  affect the
construction hereof.

Agreement and the consummation of the transactions  herein contemplated will not

contract,  indenture,  mortgage, loan agreement, note, lease or other instrument
filed as an  exhibit  to the  Registration  Statement  or as an  exhibit  to 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

         (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 



<PAGE>



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.
