The Boards of Directors of
Shelbourne Properties I, Inc.
Shelbourne Properties II, Inc.
Shelbourne Properties III, Inc.
527 Madison Avenue - 16th Floor
New York, New York 10022

Gentlemen:

     We have  been  engaged  in  discussions  contemplating  that my  affiliated
companies  ("Purchaser"),  enter into agreements  with Shelbourne  Properties I,
Inc.,  Shelbourne  Properties  II, Inc.,  and  Shelbourne  Properties  III, Inc.
(collectively, the "Companies"), with respect to tender offers for shares of the
Companies and the liquidation of their assets.

     You are hereby advised that we are prepared to complete the  transaction as
we have proposed it to you at the purchase  price for shares of the Companies as
set forth below:

                     Icahn
                     Purchase Price             Number of Shares

    HXD              $63.15                     251,785
    HXE              $73.85                     268,444
    HXF              $58.30                     236,631

     We would also agree to add to the Stock  Purchase  Agreements the following
undertakings and covenants which you designated as significant:

     1. The Equity Amount for each Company in the  calculation of "Net Proceeds"
will be modified to equal the  greater of (i) the current  Equity  Amount as set
forth in the Plan of  Liquidation  or (ii) the revised tender offer price in the
final Ashner offer  multiplied  by the current  outstanding  number of shares in
such Company.

     2.  Purchaser  will  agree  not to  acquire  or have one of its  affiliates
acquire any  property of the  Companies  or support a sale of any  property of a
Company to Northstar Capital Investment Company or its affiliates.


     3.  Purchaser's  non-independent  nominees to the Board of Directors of the
Companies will,  subject to their fiduciary  duties and existing  obligations of
the  Companies,  support  and  recommend  the  implementation  of the  following
distribution policy for the Companies:

         a. The Companies  will make  quarterly  distributions  of all operating
         cash flow in  excess  of  budgeted  capital  expenditures,  anticipated
         corporate  expenses and a reserve of 2% of the current  appraised value
         of the applicable properties.

         b. 80% of each Company's current excess net cash will be used to retire
         existing debt and/or make a distribution  to  stockholders on or before
         90 days following the election of nominees of Purchaser as directors of
         such Company.

4.       The Plans of Liquidation to be submitted for stockholder approval will
be drafted to provide that:

         a. All excess refinancing  proceeds, if any, will be distributed within
         the earlier of 30 days following the quarter in which such  refinancing
         occurs or 90 days following the refinancing.

         b. All net property sale proceeds,  if any, will be distributed  within
         the earlier of 30 days following the quarter in which such  refinancing
         occurs or 90 days following the refinancing.

     5. The Plans of Liquidation to be submitted for  stockholder  approval will
be drafted to provide that, unless  otherwise  approved by  stockholders  not
affiliated with Purchaser and so long as a majority of the Boards of Directors
consist of members nominated by Purchaser,  or by persons nominated by such
nominees,  the failure to observe the distribution policy set forth in Paragraph
4 above shall result in each of the following:

         a. Permanent elimination of the Incentive Payment.

         b.  Elimination  of any service fees payable to affiliates of Purchaser
         by the  Companies  during  the  period  in which the  distribution  was
         delayed.

         c.  Elimination  of any fees payable to directors  (other than those of
         objecting  directors) of the  Companies  during the period in which the
         distribution was delayed.

     6. If prior  to any  date set  forth  below,  stockholders  shall  not have
received aggregate distributions equal on a per share basis to:

                                       By 12/31/04    By 12/31/05    By 12/31/06
Shelbourne Properties I, Inc.          $16.00         $32.00         $48.00
Shelbourne Properties II, Inc.         $18.66         $37.33         $56.00
Shelbourne Properties III, Inc.        $14.66         $29.33         $44.00

then  Purchaser  will  vote  its  shares  at the  next  annual  meeting  of
stockholders following the first such failure for the applicable Company(ies) in
proportion to the  stockholders  not  affiliated  with  Purchaser on all matters
properly  brought  before  the  meeting  and the  applicable  Company(ies)  will
endeavor to cause such meeting to be held not later than May 30,  2005;  May 30,
2006 and May 30, 2007, as applicable.

     7. If any of the Plans of Liquidation  are not approved after being subject
to stockholder vote,  subject to their fiduciary duty, the nominees of Purchaser
will use commercially reasonable efforts to market and sell the property located
at 568 Broadway,  New York,  New York and to distribute  the proceeds  therefrom
within the earlier of 30 days following the quarter in which such sale occurs or
90 days following the sale.

     8. As a part of the  Stock  Purchase  Agreement,  I would  agree  that upon
payment of the break-up fee (up to the existing $1.5 million  obligation) to the
Ashner group, I will reimburse the Companies for such amounts when paid.

     If there are  additional  matters that should be  addressed,  or additional
matters raised in the bid by the Ashner group,  please contact us so that we may
respond promptly.

                                                     Very truly yours,


                                                     /s/ Carl C. Icahn
