                       SUPPLEMENT DATED NOVEMBER 17, 1997

                           OFFER TO PURCHASE FOR CASH
                      ANY AND ALL LIMITED PARTNERSHIP UNITS
                             AT $27.50 NET PER UNIT
                                       BY
                                 JOHN N. GALARDI


     The following  information  is intended to supplement the  information  set
forth in the Offer to Purchase dated October 27, 1997. In determining whether to
tender  Units  pursuant  to the  Offer to  Purchase  or to  withdraw  any  Units
previously  tendered,  Limited Partners should carefully  consider the following
information:

     1.   The  Offeror  is the  owner  of 50% of the  outstanding  stock  of the
          corporation  which owns 100% of the  outstanding  stock of the general
          partner of the Partnership.  Accordingly,  the Offeror is an affiliate
          of the Partnership.

     2.   The Offeror is making the Offer  because he believes that the purchase
          of Units at this time pursuant to the Offer is economically attractive
          to him.  His desire to purchase  Units at a price he deems  attractive
          may be deemed to  conflict  with the  desire of  Limited  Partners  to
          realize a higher value for their Units. Accordingly,  the interests of
          the Offeror,  an affiliate of the Partnership,  may be deemed to be in
          conflict with the interests of the Limited Partners.  However, neither
          the  Offeror  nor the  Partnership  is making  any  recommendation  to
          Limited  Partners  to tender  Units or any  representation  to Limited
          Partners  with  respect to the  adequacy  or  fairness of the price of
          $27.50 per Unit.

     3.   The  amount of $27.50  per Unit is lower  than the  Limited  Partners'
          equity  per Unit of $55.97  reported  in the  Partnership's  Quarterly
          Report on Form 10-Q for the Quarter Ended June 30, 1997 and lower than
          secondary  market prices paid for Units during the last four months of
          1996, as disclosed in Section 9 of the Offer to Purchase.

     4.   The Limited  Partners' equity in the Partnership of $55.97 per Unit is
          based on book value and not on a  currently  realizable  value for the
          Partnership's  property.  The Offeror has not had an  appraisal of the
          property performed, has no knowledge of any current appraisals and has
          not formed any  conclusion as to the current net  realizable  value of
          the  property.  The Offeror does,  however,  believe that the price of
          $27.50 per Unit represents an attractive investment to him compared to
          the value he expects the Units to have in the future.



     5.   The price of $27.50  per Unit was  determined  by the  Offeror  as the
          price  which he  believed  represented  an  attractive  price  for him
          economically.  In determining  this price, he considered the following
          factors:

            (a)  the current  offer to  purchase  Units at $21.00 per Unit by KM
                 Investments, LLC;

            (b)  that there is not a liquid market for the Units;

            (c)  that  the  Offeror  may have to hold the  Units  for a  lengthy
                 period of time;

            (d)  that the Partnership is not currently making any  distributions
                 and there is no  assurance  that the  Partnership  will  resume
                 making any distributions;

            (e)  that the  publicly  reported  prices for sales of the Units has
                 been declining; and

            (f)  the  Offeror's  personal  expectations  that  the  value of the
                 Partnership's property will increase in the future.

               The  Offeror  did not  obtain any  appraisals  or  valuations  in
          connection with his determination of the Purchase Price.

     6.   Certain historical financial information regarding the Partnership and
          certain information regarding its property is set forth on Schedules A
          and  B  hereto.  This  information  has  been  derived  from  publicly
          available  reports of the  Partnership  filed with the  Securities and
          Exchange Commission.

     7.   The scheduled  termination  date for the  Partnership  is December 31,
          2030, although it was initially expected to terminate upon the sale of
          all of its properties, and those sales were expected to commence after
          approximately  five years.  The Offeror  understands  that the General
          Partner,  however,  has elected not to sell the remaining  property at
          this time  because it does not believe  that the value it could obtain
          for the  property at this time is  attractive  and has not  determined
          when  it may  do  so.  Limited  Partners  have  the  right  under  the
          Partnership's partnership agreement to remove the General Partner by a
          majority vote.

     8.   The  Offer  will have no effect  on the  compensation  of the  General
          Partner.

     9.   The Offeror has not  considered any  transaction  other than the Offer
          with respect to any purchase of the Partnership or its assets.

     10.  The Partnership is not currently making any cash distributions because
          it does not have any cash available for  distribution in excess of its
          operating  requirements.  Neither the Offeror nor any other  person is
          obligated to contribute  funds to the Partnership to enable it to make
          distributions.



     11.  The Offeror will be obligated to purchase any Units  validly  tendered
          and not withdrawn if the  conditions  set forth in Item 8 of the Offer
          to Purchase are satisfied as of the Expiration  Date of the Offer,  as
          it may be extended. The standard which will be employed by the Offeror
          in determining whether the conditions are satisfied or shall be waived
          in his reasonable judgment.

     If you wish to tender Units, please complete, sign and return the Letter of
Transmittal.
