     The  persons  filing  this   statement  are  Longacre   Corp.,  a  Delaware

     Except as disclosed on Exhibit 2 attached hereto and  incorporated  herein,
none of Carl C. Icahn,  Longacre nor any  executive  officer of  Longacre,  has,
during  the  past  five  years,  (a) been  convicted  in a  criminal  proceeding
(excluding traffic violations or similar misdemeanors), or (b) been a party to a
civil proceeding of a judicial or administrative body of competent  jurisdiction
and as a result of such  proceeding  was or is subject to a judgment,  decree or
final  order  enjoining  future  violations  of, or  prohibiting,  or  mandating
activities  subject  to,  Federal or State  securities  laws or a finding of any
violation with respect to such laws.


Item 3.           Source and Amount of Funds or Other Consideration

     Longacre  acquired the 7,038 Shares as a result of the  conversion on April
17, 2001 of the units of Integrated Resources High Equity Partners,  L.P.-Series
88,  held by  Longacre  into the shares of the Issuer,  in  connection  with the
merger of Integrated  Resources  High Equity  Partners,  L.P.-Series 88 with and
into the  Issuer.  As of August 1, 2002,  the  aggregate  purchase  price of the
45,438  Shares  (including  the  Shares  held  as  a  result  of  the  foregoing
conversion)  purchased by Longacre was $1,701,740 (including  commissions).  The
source of funding for the purchase of these Shares was general  working  capital
of Longacre.



Item 4.           Purpose of Transaction

     On July 29, 2002,  (i) Carl C. Icahn issued a press  release (a copy of the
press  release is filed as Exhibit 3 hereto  and is  incorporated  herein in its
entirety),  indicating  that his related  companies  are  prepared to initiate a
tender  offer for the shares of the Issuer (the "Icahn  Offer"),  (ii)  Longacre
commenced  legal  actions  referred  to in the  press  release,  and  (iii)  the
Registrants  entered into negotiations with the Issuer with respect to the Icahn
Offer.  On July  31,  2002,  an  affiliate  of the  Registrants  entered  into a
confidentiality  agreement with the Issuer.  The Registrants  reserve the right,
from time to time, to acquire additional Shares and to dispose of the Shares.

Schedule 14D-9 filing, filed with the Securities and Exchange Commission on July
10, 2002).

     (b) Longacre has sole voting power and sole dispositive  power with respect
to the  45,438  Shares.  Carl C.  Icahn  has  shared  voting  power  and  shared
dispositive power with regard to the 45,438 Shares held by Longacre.

Item 2),  may be deemed to  beneficially  own (as that term is  defined  in Rule
13d-3 under the Act) the Shares which Longacre directly  beneficially  owns. Mr.
Icahn  disclaims  beneficial  ownership  of the Shares held by Longacre  for all
other purposes.

                                                            Exhibit 2

On January 5, 2001, Reliance Group Holdings, Inc. ("Reliance") commenced an
action in the United States District Court for the Southern District of New York
against  "Carl  C.  Icahn,   Icahn  Associates  Corp.  and  High  River  Limited
Partnership"  alleging  that High  River's  tender  offer for Reliance 9% senior
notes violated  Section 14(e) of the Exchange Act.  Reliance  sought a temporary
restraining  order and  preliminary and permanent  injunctive  relief to prevent
defendants  from purchasing the notes.  The Court initially  imposed a temporary
restraining  order.  Defendants then supplemented the tender offer  disclosures.
The Court  conducted a hearing on the  disclosures  and other matters  raised by
Reliance.  It then denied  plaintiffs'  motion for a preliminary  injunction and
ordered dissolution of its temporary  restraining order following  dissemination
of the supplement.

Reliance took an immediate appeal to the United States Court of Appeals for
the Second  Circuit and sought a stay to  restrain  defendants  from  purchasing
notes  during the  pendency of the appeal.  On January  30,  2001,  the Court of
Appeals denied plaintiff's stay application. On January 30, Reliance also sought
a  further  temporary  restraining  order  from the  District  Court.  The Court
considered the matter and reimposed its original  restraint  until noon the next
day, at which time the restraint was dissolved. The appeal was argued on March 9
and denied on March 22.




                                                                    Exhibit 3


                      Icahn Led Group to Make Tender Offer
               For Shares of Shelbourne Properties I, II and III.
                 Price Exceeds HX Investor's Prior Offer by 10%;
                           Reduces Liquidation Costs.


New York,  NY, July 29, 2002 - Investor Carl C. Icahn today  announced that
his related companies, together with outside investors, are prepared to initiate
competing tender offers (the "Icahn Offers") for shares of Shelbourne Properties
I, Inc. (AMEX: HXD),  Shelbourne  Properties II, Inc. (AMEX: HXE) and Shelbourne
Properties III, Inc. (AMEX: HXF) (collectively the "Companies"), as follows:

                  Icahn                     Ashner
                  Purchase Price            Purchase Price     Number of Shares

HXD               $58.30                    $53                251,785
HXE               $68.20                    $62                268,444
HXF               $53.90                    $49                236,631

Mr. Icahn noted that the prices  represent  premiums of  approximately  10%
over the share prices specified in the tender an offers previously  announced by
HX  Investors,  L.P., a company  affiliated  with Michael L. Ashner (the "Ashner
Offers").  In order to preserve REIT status, the Icahn Offers will be structured
in a manner to assure that no individual exceeds 8% beneficial ownership of each
Company.

The Icahn  Offers  will be on the same terms and  conditions  as the Ashner
Offers and will  contemplate  that the Companies and their affiliates will enter
into agreements  substantially  similar to those entered into with HX Investors,
L.P.  and its  affiliates,  including  the  grant by the  Companies  of  similar
approvals,  waivers  and  consents.  However,  rather  than the charge of 25% of
liquidation  proceeds included in the HX Investors deal, Icahn indicated that he
would accept a reduced  amount of 15% which would be  structured  in a manner to
comply with legal requirements applicable to REITs. In that regard, an affiliate
of Mr. Icahn is today commencing  legal actions  challenging the legality of the
Ashner Offers, which include allegations  concerning the effects that the Ashner
Offers and the related 25% liquidation charge may have on the REIT status of the
Companies and the after-tax  proceeds available to shareholders and the adequacy
of the disclosures set forth in the Ashners Offers. The Icahn Offers will not be
subject to financing.

Mr. Icahn  indicated that his  affiliates are prepared to meet  immediately
with the Companies to complete any necessary documentation.  Mr. Icahn stated "I
believe  that the  Shelbourne  Board  agreed  to a deal  that  does not  provide
sufficient value to shareholders. The strength of that belief is reflected in my
willingness to increase the tender price by 10% above the Ashner Offers approved
by the Board and to reduce the  liquidation  cost.  I call on the members of the
Shelbourne  Board of Directors to act promptly to facilitate  the  completion of
this bid. The Board of Directors  should also carefully  review the  allegations
set forth in the litigation  being  commenced  today when  considering,  as they
must, the best interests of shareholders."


The  Icahn  Offers  will be  conditioned  on the  termination  of the Stock
Purchase  Agreements  dated  as of July  1,  2002  between,  among  others,  the
Companies and HX Investors in  accordance  with their terms and on the designees
of HX Investors not being appointed to the Board of Directors of the Companies.

Upon the  commencement of any tender offer,  the bidders will file a tender
offer statement with the Securities and Exchange Commission. That statement will
contain  important  information  about the  tender  offer and  should be read by
security holders.  In that event,  security holders will be able to obtain at no
charge (i) the tender  offer  statement  and other  documents  when they  become
available   on   the   Securities   and   Exchange   Commission's   website   at
http://www.sec.gov and (ii) the offer to purchase, the letter of transmittal and
the notice of  guaranteed  delivery  from the  information  agent for the tender
offer.
