                             OLYMPIA INVESTORS, L.P.


             THE OFFER, WITHDRAWAL RIGHTS AND PRORATION PERIOD WILL
                    EXPIRE AT 5:00 P.M., NEW YORK CITY TIME,
             ON FRIDAY, JULY 17, 1998, UNLESS THE OFFER IS EXTENDED.







         Olympia   Investors,   L.P.,  a  Delaware   limited   partnership  (the
"Purchaser"),  hereby supplements and amends its offer to purchase up to 148,500
units of limited partnership interest (the "Units") in High Equity Partners L.P.
- - Series 88 (the  "Partnership"),  upon the terms and subject to the  conditions
set  forth in the  Purchaser's  Offer to  Purchase  dated  March  12,  1998,  as
supplemented  and  amended by this  Supplement  dated July 1, 1998 (as it may be
further  supplemented or amended from time to time, the "Offer to Purchase") and
in the related  Assignment of Partnership  Interest,  including the Instructions
thereto (as it may be supplemented or amended from time to time, the "Assignment
of  Partnership  Interest",  which,  collectively  with the  Offer to  Purchase,
constitutes the "Offer").  Capitalized  terms used but not otherwise  defined in
this Supplement shall have the meanings set forth in the Offer to Purchase.

         1. All  references  in the Offer to Purchase to the Purchase  Price are
hereby  amended to reflect an increase  in the  Purchase  Price from  $117.00 to
$125.50 per Unit.

         2. All  references  in the  Offer to  Purchase  to the  number of Units
sought are hereby  amended to reduce such number  from  148,500  Units to 55,760
Units.  The last sentence of the first  paragraph on the front cover page of the
Offer to Purchase is hereby amended and  supplemented to read in its entirety as
follows:

         The 55,760 Units sought pursuant to the Offer  represent  approximately
         15% of the total Units outstanding as of March 31, 1998.

         3.  The  second  paragraph  on the  front  cover  page of the  Offer to
Purchase and the second paragraph of the "Introduction" to the Offer to Purchase
are each hereby amended and supplemented to read in their entirety as follows:

                  The Purchaser is not  affiliated  with  Resources High Equity,
         Inc.,  Resources  Capital  Corp.  or  Presidio  AGP Corp.,  the general
         partners of the  Partnership  (the "General  Partners").  However,  the
         Purchaser has entered into an agreement (the "Agreement") with Presidio
         Capital Corp. ("Presidio"), which indirectly owns all of the issued and
         outstanding  capital stock of the General Partners,  pursuant to which,
         among other  things and subject to the terms and  conditions  set forth
         therein:  (i) the Purchaser has granted  Presidio the right to purchase
         50% of the Units  acquired by the  Purchaser  pursuant to the Offer and
         the Purchaser's  offers for Units of two related  limited  partnerships
         (the "Related  Partnerships");  (ii) either party can initiate buy/sell
         procedures pursuant to which the non-initiating party would be required
         to elect either to buy certain  Units from the  initiating  party or to
         sell certain Units to the initiating party; (iii) the Purchaser and its
         affiliates  have agreed that,  prior to the Standstill  Expiration Date
         (generally defined to mean March 6, 2001,  although such date may occur
         earlier  than  March 6,  2001 upon the  occurrence  of  certain  events
         described in the Agreement) they

                                       -1-

<PAGE>



         will not: seek the removal of the General Partners, call any meeting of
         limited partners or seek to control the management, policies or affairs
         of the  Partnership  or the Related  Partnerships,  effect any business
         combination or other  extraordinary  transaction  with the Partnership,
         any Related Partnership or their general partners,  acquire Units other
         than  pursuant  to the  Offers or acquire  properties  or assets of the
         Partnership or any Related  Partnership;  (iv) subject to the amendment
         described below, the Purchaser and its affiliates have agreed, prior to
         the  Standstill  Expiration  Date,  to vote  their  Units in favor of a
         proposal,  if any, by the General Partners that would result in Limited
         Partners  receiving  securities that are listed on NASDAQ or a national
         securities exchange;  and (v) Presidio has agreed to cause the partners
         of the  Partnership  and  the  Related  Partnerships  to  cooperate  to
         facilitate  the Offers.  The Agreement has been amended to provide that
         the Purchaser and its  affiliates  will not be obligated to vote Units,
         and the Purchaser and its affiliates have determined that they will not
         vote Units, in favor of a proposal that is made in contravention of the
         undertaking of the General  Partners  described in the second paragraph
         of  Section  8 of  this  Supplement.  Section  12  ("Background  of the
         Offers")  contains a more  detailed  description  of the  Agreement and
         amendments thereto.

                  As a result of the  Agreement,  Presidio,  W. Edward  Scheetz,
         David  Hamamoto  and  NorthStar   Capital  Partners  (who  directly  or
         indirectly  control  Presidio),   Millenium  Funding  Corp.,  Millenium
         Funding IV Corp.,  Presidio Holding Company,  LLC,  NorthStar  Presidio
         Management Company, LLC, NorthStar Operating, LLC and NorthStar Capital
         Holdings I, LLC (collectively,  the "Presidio Bidders"),  may be deemed
         to be "co-bidders" with the Purchaser.

         4. The text of the second  bullet  point on the inside front cover page
of the Offer to Purchase  and the second  bullet  point under the heading  "Some
Factors To Be Considered By Limited  Partners" in the  Introduction to the Offer
to Purchase are each hereby amended and  supplemented  to read in their entirety
as follows:

         The Purchase  Price of $125.50 per Unit is  approximately  80.4% of the
         Purchaser's  estimate  of the net asset  value per Unit of $156.05  and
         approximately  84.5% of the Purchaser's  estimate of liquidation  value
         per Unit of $148.55 (each of which amounts includes $5.95 per Unit that
         the General  Partners have disclosed they estimate would be required to
         be  paid  by  them  to  Limited   Partners  upon   liquidation  of  the
         Partnership).   See  Section  13  ("Purchase  Price   Considerations").
         Schedule III to this  Supplement  contains  information  regarding  the
         General  Partners'  calculation  of Revised  Deemed Net Asset Value Per
         Unit ($150.10 per Unit)and the May 1998 appraisals of the Partnership's
         properties on which such calculation is based.

         5. The first paragraph beneath the final bullet point under the heading
"Some Factors To Be Considered By Limited  Partners" in the  Introduction to the
Offer to Purchase is hereby amended and  supplemented to read in its entirety as
follows:

         Although not  necessarily an indication of value,  the $125.50 per Unit
         Purchase Price is a premium over the $103.19 per Unit weighted  average
         selling price for Units reported for the limited and sporadic secondary
         market during the six-month period ended March 31, 1998. See Section 13
         ("Purchase Price Considerations"). Such secondary market selling prices
         do not take into account commissions charged by secondary market makers
         effectuating such sales and other transaction costs.

         6. The second  sentence of the first  paragraph of Section 1 ("Terms of
the Offer;  Expiration  Date;  Proration")  of the Offer to  Purchase  is hereby
amended and supplemented to read in its entirety as follows:

         For purposes of the Offer, the term  "Expiration  Date" shall mean 5:00
         p.m.,  New York  City  time,  on  Friday,  July 17,  1998,  unless  the
         Purchaser in its sole discretion shall have extended the period of time

                                       -2-

<PAGE>



         for which the Offer is open, in which event the term "Expiration  Date"
         shall mean the latest time and date on which the Offer,  as extended by
         the Purchaser, shall expire.

         7. Section 3 ("Procedure for Tendering Units") of the Offer to Purchase
is hereby  supplemented  and amended by adding the  following  at the end of the
paragraph entitled "Valid Tender":

         Anything  herein  to the  contrary  notwithstanding,  Limited  Partners
         should furnish Certificates evidencing tendered Units to the Depositary
         only if available.  It is not necessary to furnish such Certificates in
         order for your tender to be valid.

         8. Section 8 ("Future Plans of the Purchaser") of the Offer to Purchase
is hereby  supplemented  and amended by adding the  following at the end of such
Section:

         The Presidio  Bidders have  furnished the Purchaser  with the following
         information regarding their plans with respect to the Partnership:

                  The General  Partners  are actively  considering  a variety of
         plans to enhance the value and  liquidity of the Units.  The plans have
         included possible conversion of the Partnership into an actively traded
         real estate investment trust (a  "Reorganization  Plan").  Although the
         terms of a Reorganization Plan have not been defined, it is the present
         intention  of  the  General  Partners  that,  if  a  Reorganization  is
         effected,  the fees to them and their  affiliates  from the Partnership
         would not  increase  from their  existing  level (see  Schedule I), and
         their equity interest in the Partnership as general  partners would not
         increase from the existing level.  The trading price for the securities
         that would be issued in  exchange  for the Units  could be more or less
         than the trading price currently  available in the secondary  market. A
         Reorganization  Plan would require as a condition to its  consummation,
         among  other  things,  the  approval  by holders  of a majority  of the
         outstanding Units. There can be no assurance a Reorganization  Plan, or
         any other plan, will actually be proposed by the General Partners,  or,
         if  proposed,  will  be  approved  by  holders  of a  majority  of  the
         outstanding Units or consummated.  However, if a Reorganization Plan is
         proposed by the  General  Partners  and subject to the next  succeeding
         paragraph,  the General  Partners expect that they and their affiliates
         would vote all Units  they own at the time in its  favor,  and that the
         Purchaser and its affiliates  would vote all Units they own at the time
         in its favor.  At present,  the General  Partners and their  affiliates
         beneficially own, in the aggregate, 12.7% of the outstanding Units, and
         the Purchaser has advised that it and its affiliates  beneficially own,
         in the  aggregate,  0.6% of the  outstanding  Units.  If the  Purchaser
         acquires a substantial  number of Units in the Offer, the likelihood of
         approval of a Reorganization Plan, if proposed, would be enhanced.

                  The General  Partners have determined that, prior to the first
         anniversary  of the completion of the Offer,  the General  Partners and
         their affiliates will not solicit approval by the Limited Partners for,
         or  consummate,  a  transaction,  or  series of  related  transactions,
         constituting a "roll-up  transaction" (within the meaning of Regulation
         S-K,  Item 901),  other than a  conversion  of the  Partnership  into a
         stand-alone  (i.e.,  not part of another entity or entities),  actively
         traded,  real estate  investment  trust pursuant to Section 3(a)(10) of
         the  Securities  Act of 1933,  where the terms  and  conditions  of the
         transaction,  or series of related transactions,  including any related
         tender  offer  for  Units  or any  sale  or  financing  of  Partnership
         properties,  are  approved,  after a hearing  upon the fairness of such
         terms and  conditions  at which all Limited  Partners have the right to
         appear,  by the court in connection with a settlement of the litigation
         described in paragraph 12 of Schedule III to this Supplement.

                  Except as set forth herein,  the Presidio  Bidders do not have
         any present  plans or  proposals  which relate to or would result in an
         extraordinary transaction, such as a merger, reorganization or

                                       -3-

<PAGE>



         liquidation,  involving  the  Partnership;  a  sale  or  transfer  of a
         material amount of the Partnership's  assets; any change in composition
         of  the   Partnership's   senior   management  or  personnel  or  their
         compensation;  any changes in the Partnership's present  capitalization
         or   distribution   policy;   or  any  other  material  change  in  the
         Partnership's structure or business.

         9. Section 9 ("Certain  Information  Concerning  the  Partnership")  is
hereby  supplemented  and  amended  by adding the  following  at the end of such
Section:

                  On April 15, and May 15, 1998,  respectively,  the Partnership
         filed with the  Commission  its Annual Report on Form 10-K for the year
         ended December 31, 1997 (the "1997 Form 10-K") and its Quarterly Report
         on Form 10-Q for the  quarter  ended March 31, 1998 (the "March 31 Form
         10-Q").  The  information  set forth below has been  excerpted from the
         1997 Form 10-K and the March 31 Form 10-Q. More comprehensive financial
         and other  information  is included in the 1997 Form 10-K, the March 31
         Form  10-Q  and  other  documents  filed  by the  Partnership  with the
         Commission,  and the  information  set forth below is  qualified in its
         entirety by reference to the 1997 Form 10-K, the March 31 Form 10-Q and
         such other  documents  and all the  financial  information  and related
         notes contained therein.

                  The 1997 Form 10-K reports  that, as of and for the year ended
         December 31, 1997, the  Partnership  had:  Revenues of $9,189,172;  Net
         Income of $3,708,687;  Net Income Per Unit of $9.48;  Distributions Per
         Unit of $9.69; and Total Assets of $56,296,853.  The March 31 Form 10-Q
         reports  that,  as of and for the  quarter  ended March 31,  1998,  the
         Partnership had: Revenues of $2,205,607;  Net Income of $1,108,380; Net
         Income Per Unit of $2.83;  Distributions  Per Unit of $2.55;  and Total
         Assets of $56,233,365.

         10.  The  heading  to  Section  10 to the Offer to  Purchase  is hereby
supplemented and amended to read as follows:

         SECTION 10.  INFORMATION CONCERNING THE PURCHASER, PRESIDIO AND THEIR
         AFFILIATES

and the  text of  Section  10 is  hereby  supplemented  and  amended  to add the
following at the end of such Section:

                  Exhibit  A  to  this  Supplement   contains  AREH's  unaudited
         financial  statements  for the fiscal year ended  December 31, 1997 and
         the three  months  ended  March 31,  1998.  AREH is not  subject to the
         periodic  reporting  requirements  of the  Exchange  Act and  does  not
         prepare  audited  financial  statements  in the ordinary  course of its
         business.  Accordingly,  such  audited  financial  statements  are  not
         available or obtainable without unreasonable cost or expense.

                  For certain  information  furnished  by the  Presidio  Bidders
         concerning  Presidio and certain of its  affiliates,  and the executive
         officers and directors of Presidio and such affiliates,  see Schedule I
         to this Supplement.

                  Schedule II to this Supplement contains information  furnished
         by the  Presidio  Bidders  about the  beneficial  ownership of Units by
         Presidio and its affiliates,  as well as transactions in Units effected
         by them since  December  31,  1995.  Except as  otherwise  set forth in
         Schedule II to this Supplement,  (i) neither  Presidio,  to the best of
         Presidio's knowledge,  the persons or entities identified on Schedule I
         nor any affiliate of the foregoing  beneficially owns or has a right to
         acquire any Units;  (ii) neither  Presidio,  to the best of  Presidio's
         knowledge, the persons or entities identified on Schedule I nor any

                                       -4-

<PAGE>



         affiliate  of the  foregoing,  or any  director,  executive  officer or
         subsidiary of any of the foregoing, has effected any transaction in the
         Units within the past 60 days; (iii) neither  Presidio,  to the best of
         Presidio's  knowledge,  any of the  persons or entities  identified  on
         Schedule  I,  nor  any  director  or  executive  officer  of any of the
         foregoing, has any contract, arrangement, understanding or relationship
         with  any  other  person  with  respect  to  any   securities   of  the
         Partnership,  including,  but not limited to, contracts,  arrangements,
         understandings  or  relationships  concerning  the  transfer  or voting
         thereof,  joint ventures,  loan or option arrangements,  puts or calls,
         guarantees  of  loans,   guarantees  against  loss  or  the  giving  or
         withholding  of  proxies;  (iv)  there  have  been no  transactions  or
         business relationships that would be required to be disclosed under the
         rules and  regulations  of the Commission  between  Presidio or, to the
         best of  Presidio's  knowledge,  the persons or entities  identified on
         Schedule  I,  on the  one  hand,  and  the  Partnership  or  its  other
         affiliates,  on the other hand;  and (v) there have been no  contracts,
         negotiations  or  transactions  between  Presidio  or,  to the  best of
         Presidio's knowledge, the persons or entities identified on Schedule I,
         on the one hand, and the  Partnership or its other  affiliates,  on the
         other hand, concerning a merger,  consolidation or acquisition,  tender
         offer or other acquisition of securities, an election of directors or a
         sale or other transfer of a material amount of assets.

                  The  General   Partners  of  the  Partnership  have  furnished
         Unitholders  with a  Schedule  14D-9,  as amended on May 21 and July 1,
         1998 (as amended, the "Schedule 14D-9"),  which states that the General
         Partners  are  expressing  no opinion and are  remaining  neutral  with
         respect  to the  Offer.  Schedule  III to this  Supplement  sets  forth
         information in Item 4 to the Schedule  14D-9,  which sets forth certain
         factors the General  Partners  believe  Unitholders  should consider in
         deciding whether to accept or reject the Offer.

         11. The first  sentence  of Section 11 ("Source of Funds") of the Offer
to  Purchase  is hereby  amended  and  supplemented  to read in its  entirety as
follows:

         The Purchaser expects that approximately  $6,997,880 (exclusive of fees
         and expenses) will be required to purchase 55,760 Units, if tendered.

         12. Section 12  ("Background of the Offer") of the Offer to Purchase is
hereby  amended  and  supplemented  by deleting  the last  sentence of the third
paragraph and adding the following in lieu thereof:

                  The  Partnership  obtained new appraisals of its properties in
         May 1998 (the "May 1998 Appraisal  Information").  Schedule III to this
         Supplement contains a description of the May 1998 Appraisal Information
         provided by the Presidio Bidders.

                  On May 20, 1998 the Purchaser,  AREH and Presidio  amended the
         Agreement to provide for  cross-indemnification  agreements by AREH and
         Presidio  with  respect  to  certain   liabilities  under  the  federal
         securities laws relating to information provided in connection with the
         Offer  and  offer  for  Units of the  Related  Partnerships  concerning
         themselves and their respective affiliates who are co-bidders.  On June
         29,  1998,  the  Purchaser,  AREH  and  Presidio  further  amended  the
         Agreement to provide that the Purchaser and its affiliates  will not be
         obligated to vote Units,  and the  Purchaser  and its  affiliates  have
         determined  that they will not vote Units,  in favor of a proposal that
         is made in  contravention  of the  undertaking of the General  Partners
         described in the second paragraph of Section 6 of this Supplement.

         13.  Section  13  ("Purchase  Price  Considerations")  of the  Offer to
Purchase is hereby amended and supplemented as follows:

         a. The  following  is added after the table in the third  paragraph  of
said Section:

                                       -5-

<PAGE>



         According to THE PARTNERSHIP  SPECTRUM,  for the two months ended March
         31, 1998, a total of 2,216 Units traded at per Unit prices between $110
         and $120 per Unit with a weighted  average of $110.30  per Unit.  Based
         upon  information  reported by THE PARTNERSHIP  SPECTRUM,  the weighted
         average  price per Unit for the six  months  ended  March 31,  1998 was
         $103.19.

         b. The  fourth  paragraph  of said  Section  is  amended to read in its
entirety as follows:

                  Paragraph 1 of Schedule III to this Supplement  discloses that
         the General Partners estimate the "Revised Net Asset Value Per Unit" to
         be $150.10.  Paragraph  1 states that  Revised Net Asset Value Per Unit
         was determined based upon the May 1998 Appraisal  Information and takes
         into  account  the other  assets  and  liabilities  of the  Partnership
         reflected on the Partnership's March 31, 1998 balance sheet.

         c. The following  sentence is added in lieu of the last sentence of the
fifth paragraph of said Section:

         Additional  information  concerning  statements  made  by  the  General
         Partners of the Partnership  concerning their plans for the Partnership
         is set forth in Item 8 of this Supplement and in Schedule III hereto.

         d. The sixth and  seventh  paragraphs  of said  Section are amended and
restated to read in their entirety as follows:

                  The  Purchase  Price   represents  80.4%  of  the  Purchaser's
         estimate of net asset value per Unit ("NAV  Estimate") and 84.5% of the
         Purchaser's estimate of liquidation value per Unit.

                  NAV ESTIMATE.  The  Purchaser's NAV Estimate equals the sum of
         (i) the amount that the Limited  Partners  would  receive in connection
         with a  hypothetical  sale of all of the  Partnership's  properties  at
         their  estimated  aggregate  value  (based upon the May 1998  Appraisal
         Information,  which is described in Schedule III to this  Supplement));
         (ii) the  Partnership's  net current  assets as of March 31, 1998;  and
         (iii) an additional  $2,212,013 (the "Clawback  Amount"),  which is the
         General Partners' estimate of the amount that the Partnership Agreement
         would  require the General  Partners to pay to the Limited  Partners if
         the  Partnership  were  liquidated  now and realized the values for its
         properties  reflected  in  the  May  1998  Appraisal  Information.  The
         Purchaser's  NAV Estimate does not take into  account:  (i) real estate
         transaction costs that would be incurred on a sale of the Partnership's
         properties, such as brokerage commissions and other selling and closing
         expenses;  (ii) timing  considerations;  or (iii) costs associated with
         winding  up the  Partnership.  The  disclosure  set forth  herein  with
         respect to the May 1998  Appraisal  Information  has been  derived from
         information  furnished  by the Presidio  Bidders for  inclusion in this
         Supplement and the Schedules  hereto and information  publicly filed by
         the  Partnership.  Although the Purchaser has no  information  that any
         statements   contained  herein  based  upon  such  May  1998  Appraisal
         Information  or  information  publicly  filed  by the  Partnership  are
         untrue,  the Purchaser cannot take  responsibility  for the accuracy or
         completeness  of the May  1998  Appraisal  Information  or  such  other
         information.

         e. The second,  third and fourth paragraphs  following the caption "NAV
Estimate" in said Section are deleted in their entirety.

         f. The first two sentences of the paragraph  immediately  following the
caption  "Liquidation  Value"  in said  Section  are  amended  to read in  their
entirety as follows:


                                       -6-

<PAGE>



         In estimating  liquidation  value per Unit, the Purchaser  adjusted its
         NAV  Estimate by  deducting a reserve  equal to 5% of such NAV Estimate
         (net of the Clawback Amount), which represents the Purchaser's estimate
         of the costs of brokerage  commissions,  title costs,  legal fees, real
         estate  transfer  taxes and other  disposition  expenses  (but does not
         include any estimate of the costs of conducting a consent  solicitation
         in order to obtain the Limited  Partners'  approval for property sales,
         as may be required  by the  Partnership  Agreement,  or of the costs of
         winding up the  Partnership,  because of the  difficulty  of estimating
         those  amounts).   The  result  of  $148.55  per  Unit  represents  the
         Purchaser's  estimate of the aggregate net liquidating proceeds payable
         to Limited  Partners  (before  provision for the costs described in the
         parenthetical  to the preceding  sentence) that could be realized in an
         orderly  liquidation  of the  Partnership,  based  on  the  assumptions
         implicit in the calculations describe above.

         14. The second  sentence of the  introductory  paragraph  of Section 14
("Conditions  of the  Offer") of the Offer to  Purchase  is hereby  amended  and
supplemented to read in its entirety as follows:

         Furthermore,  notwithstanding  any  other  term  of  the  Offer  and in
         addition to the  Purchaser's  right to  withdraw  the Offer at any time
         before the  Expiration  Date,  the  Purchaser  will not be  required to
         accept for payment or pay for any Units not  theretofore  accepted  for
         payment  or paid for and may  terminate  or amend  the Offer as to such

                                   SCHEDULE I


                                    PRESIDIO


         The  Partnership is one of a series of three public  partnerships  (the
"HEP Partnerships")  that invested in unleveraged  commercial real estate in the
period 1985-1989.  Subsidiaries of Presidio serve as general partners and hold a
5.0% interest in each of the HEP Partnerships.

         The HEP  Partnerships and their general partners are subject to a class
action lawsuit alleging,  among other things, that the general partners caused a
waste of the HEP Partnerships'  assets by collecting  management fees in lieu of
pursuing  a  strategy  to  maximize  the value of the  investments  owned by the
limited  partners;  that the general partners breached their duty of loyalty and
due care to the limited partners by expropriating management fees without trying
to run the HEP Partnerships  for the purposes for which they are intended;  that
the  general  partners  are  acting  improperly  to enrich  themselves  in their
position of control over the HEP  Partnerships  and that their  actions  prevent
non-affiliated  entities  from making and  completing  tender offers to purchase
outstanding units of limited partnership interest;  that by refusing to seek the
sale of the HEP Partnerships'  properties,  the general partners have diminished
the value of the  limited  partners'  equity in the HEP  Partnerships;  that the
general  partners have taken heavily  overvalued  partnership  asset  management
fees;  and that units of limited  partnership  interest  were sold and  marketed
through the use of false and misleading  statements.  The HEP  Partnerships  and
their general partners believe that each of the claims asserted is meritless and
intend to continue vigorously to defend the action. See Schedule III.

         Presidio  and  its  subsidiaries  are  managed  by  NorthStar  Presidio
Management  Company,  LLC ("NP Management")  pursuant to a management  agreement
dated as of November 4, 1997 (the "Presidio  Management  Agreement").  Under the
Presidio Management Agreement,  NP Management oversees the day-to-day management
of Presidio,  and has full  discretion and  authority,  without the need for any
subsequent  approval of the board of directors or shareholders  of Presidio,  or
any  subsidiary,   except  as  expressly  required  by  Presidio's  organization
instruments,  or otherwise  required by law, to manage Presidio's assets in such
manner as NP Management considers appropriate,  subject to certain restrictions.
Presidio  has  agreed  to  pay NP  Management  a  monthly  fee  of  $100,000  in
consideration  for its services  under the  Presidio  Management  Agreement.  NP
Management  is required to render its  management  services at its own  expense.
Presidio  is  responsible  for  all  other  expenses  relating  to  its  assets,
including, without limitation, services of attorneys,  accountants,  consultants
and other third party  professionals,  and other  operating  expenses,  and must
periodically  reimburse  NP  Management  for any such  expenses  advanced  by NP
Management.

         Under  the  Presidio  Management  Agreement,  Presidio  has  agreed  to
indemnify  NP  Management  and its  affiliates  and their  respective  officers,
directors,  partners,  employees  and  agents  (including,  without  limitation,
persons  serving as officers of  Presidio)  from losses,  provided,  among other
things,  that such losses  resulted  from (i) a mistake of judgment or action or
inaction taken by such person in connection  with NP  Management's  duties under
the Presidio  Management  Agreement  honestly and in good faith that such person
reasonably  believed  to be in  the  best  interest  of  Presidio  or  (ii)  the
negligence,  dishonesty  or bad faith of any agent  selected by such person with
reasonable care on behalf of Presidio.

         Presidio and two of its non-U.S.  subsidiaries,  Presidio GP Corp.  and
Presidio  LP Corp.  (collectively,  the "BVI  Group"),  have each  entered  into
administration  agreements (the  "Hemisphere  Administration  Agreements")  with
Hemisphere  Management  (Cayman)  Limited  ("Hemisphere"),   pursuant  to  which
Hemisphere  acts as the BVI  Group's  offshore  administrator.  Pursuant  to the
Hemisphere Administration Agreements,  Hemisphere shall, among other things, (i)
provide office facilities, personnel and

                                       I-1

<PAGE>



accommodations required by the BVI Group in the Cayman Islands; (ii) communicate
with  shareholders  and the  general  public on the BVI  Group's  behalf;  (iii)
maintain corporate books and records and a shareholder  register;  (iv) call and
hold all meetings of  shareholders  and  directors;  (v) disburse all  necessary
payments on behalf of the BVI Group;  and (vi) accept  subscriptions  for shares
and make  redemptions  and  repurchases  of shares,  in each case subject to the
provisions of the Memorandum and Articles of the respective companies within the
BVI Group and under the supervision of their respective  directors and officers.
In  consideration  for such services,  Hemisphere  receives a fee of $36,000 per
annum from  Presidio  and $4,000 from each of Presidio GP Corp.  and Presidio LP
Corp.  (subject to annual  review and  reduction in certain  circumstances)  and
reimbursement of its out-of-pocket  expenditures.  The Hemisphere Administration
Agreements  are  effective  for  successive  one-year  terms,  unless  and until
terminated  by either party on 30 days'  written  notice to the other party,  or
upon written  notice of the  occurrence of any breach and a failure to cure such
breach within 10 days thereafter.

                  The General  Partners have been allocated 5% of the net income
(losses) of the Partnership, which amounted to $185,434, $107,609 and ($363,025)
for the years ended December 31, 1997, 1996 and 1995, respectively, and received
$189,603,  $136,966  and  $136,966  as its 5%  share of  distributions  for such
respective  periods.  During 1997, Wexford Management LLC, formerly an affiliate
of  the  General  Partners,  received  expense  reimbursements  of  $42,997  for
performing administrative services for the Partnership.

                  Under  the  Partnership's   partnership   agreement,   if  the
compensation  paid to the General Partners and their affiliates over the term of
the Partnership  exceeds certain maximum amounts determined by formula under the
partnership  agreement,   then,  in  connection  with  the  liquidation  of  the
Partnership,  the General  Partners  are  obligated  to repay such excess to the
limited  partners.  Although  such amount can only be  determined at the time of
liquidation (which is not required for a number of years), it is estimated that,
if the  Partnership  were  liquidated now and realized the appraised  values set
forth in Schedule III, the General Partners would be obligated to pay $2,212,013
to the limited  partners.  However,  such amount could be reduced in  connection
with future Partnership operations.  Through ownership of an aggregate of 47,270
Units  (I.E.,  12.7% of the  outstanding  Units) by  affiliates  of the  General
Partners  (excluding  Units  affiliates of the General Partners may acquire from
the Purchaser, as described in the Offer to Purchase, the potential liability of
the General Partners is effectively reduced.

                  The  General  Partners  are  subject to certain  conflicts  of
interest in connection  with the Offer.  Under the agreement  with the Purchaser
described  in the Offer to Purchase,  an  affiliate of the General  Partners has
agreed,  among other things, to cooperate,  and to cause the General Partners to
cooperate,  to facilitate the Offer and to take a neutral stance with respect to
the Offer. In addition,  the partnership  agreement  provides that,  without the
concurrence  of the  General  Partners,  a majority  in  interest of the limited
partners  may vote to remove  the  General  Partners  or amend  the  partnership
agreement   (including  amending  certain  fees  and  compensation   payable  or
authorized  to be payable to the  General  Partners  or their  affiliates);  the
ownership of a large block of Units by any person  increases the  likelihood the
General  Partners may be removed or the  partnership  agreement  may be amended,
should  that person  become a limited  partner or  otherwise  acquire the voting
rights  of a  limited  partner.  In  addition,  since  the  property  management
arrangements  between affiliates of the General Partners and the Partnership are
terminable,  removal of the General Partners or the amendment of the partnership
agreement  could  result  in a  reduction  of  management  fee  income  from the
Partnership to such affiliates. If a large number of Units are tendered pursuant
to the Offer,  the  likelihood  of such  removal or  amendment  could  increase.
However, as described in The Offer to Purchase,  the Purchaser has agreed, among
other  things,  (i)  subject  to  certain  terms  and  conditions,  to permit an
affiliate of the General  Partners to purchase  Units the Purchaser  acquires in
the  Offer and (ii) not to  acquire  Units,  other  than in the  Offer,  or take
certain other action for  approximately  three years.  Accordingly,  during that
three-year  period,  the  Purchaser  will not be in a position  unilaterally  to
remove  the  General  Partners  or  amend  the  partnership  agreement,  and  if
affiliates of the General  Partners  acquire  Units from the Purchaser  that the
Purchaser

                                       I-6

acquires in the Offer, it may become increasingly  difficult for any other party
to acquire a large block of Units and affect management of the Partnership.

                                   SCHEDULE II

                  (a) Except as set forth below, neither the Partnership nor the
General  Partners have effected any transactions in the Units during the past 60
days.  Except as set forth  below,  the  General  Partners  are not aware of any
transactions  in the  Units  during  the  past 60  days by any of its  executive
officers directors, affiliates or subsidiaries.

                       At   present,   affiliates   of  the   General   Partners
beneficially  own an  aggregate  of 47,270  Units,  or 12.7% of the  outstanding
Units, all of which are owned directly by wholly-owned subsidiaries of Presidio.

                  (b) Neither the General  Partners nor, to the knowledge of the
General  Partners,  any of their executive  officers,  directors,  affiliates or
subsidiaries  intend to tender Units owned by them to the Purchaser  pursuant to
the Offer.

                       Since April 1996, wholly-owned  subsidiaries of Presidio,
of  which  the  General  Partners  are  themselves  wholly-owned   subsidiaries,
purchased  the  numbers of Units set forth below at the prices  indicated.  Each
transaction was effected in a brokerage transaction, except for the transactions
on April 22, 1996, May 13, 1996, October 21, 1996,  December 3, 1996, January 6,
1997, December 9, 1997, January 6, 1998, February 5, 1998 and February 11, 1998,
which were privately negotiated transactions.

</TABLE>

Of the Units listed above,  the 17,584 Units  purchased on February 5, 1998 at a
price of $128.00 per Unit were  purchased  at a price in excess of the  Purchase
Price in the Offer. All of the foregoing  purchases of Units were for investment
purposes and with a view to making a profit.  Although such  purchases  were not
intended as steps in furtherance of a Reorganization  Plan, the General Partners
believe  the  effect of such  purchases  may be to  enhance  the  ability of the
General  Partners and their  affiliates to control the  Partnership and effect a
Reorganization Plan.

                                  SCHEDULE III

                  (a) The General  Partners  are  expressing  no opinion and are
remaining neutral with respect to the Offer.

                  (b) In May 1998,  the  Partnership  obtained new appraisals of
the Partnership's  properties (the "New Appraisal  Information"),  which reflect
appraised  values  that  average  approximately  3%  greater  than  those in the
appraisal  information the General Partners  obtained in the summer of 1997. The
purchase price being offered by the Purchaser is 16% less than $150.10, which is
an amount (the  "Revised  Deemed Net Asset Value Per Unit") equal to (i) the sum
of the appraised value of the limited partners' share of the Partnership's  real
estate assets (based on the New Appraisal  Information)  plus the  Partnership's
net current assets at March 31, 1998 (based on the  Partnership's  balance sheet
at that  date),  divided  by (ii) the number of  outstanding  Units at March 31,
1998. However, the Offer provides Unitholders with the immediate  opportunity to
liquidate their investment in the Partnership at a price that generally  exceeds
recent secondary market selling prices for Units.  Certain  Unitholders may find
that 16% discount  acceptable,  if they want the certainty of an immediate  cash
purchase  in  exchange  for  their  Units.  Other  Unitholders  who do not  want
immediate cash,  however,  may prefer to continue to retain their  investment in
the  Partnership  and  potentially  receive a greater  amount  for their  Units.
Because of differing motivations  Unitholders may have, the General Partners are
not making a recommendation and are remaining neutral with respect to the Offer.
See Item 3(b)(i) in the Solicitation/Recommendation  Statement on Schedule 14D-9
originally  filed with the Securities and Exchange  Commission on March 25, 1998
(the "Original Schedule 14D-9") regarding certain conflicts of interest to which
the General Partners are subject.

                  Although the General  Partners are not making a recommendation
with  respect to the Offer,  the General  Partners  believe  Unitholders  should
consider,  among others,  the following factors in deciding whether to accept or
reject the Offer:

                  1. Although the value of the Units is not certain and there is
no established public trading market for the Units, the Revised Deemed Net Asset
Value Per Unit estimated by the General  Partners is $150.10,  compared with the
$125.50 per Unit price in the Offer. The Revised Deemed Net Asset Value Per Unit
was  determined  based on  independent  third party  appraisals  obtained by the
Partnership in May 1998, and take into account the other assets and  liabilities
of the Partnership  reflected on the Partnership's March 31, 1998 balance sheet.
The  Revised  Deemed Net Asset Value Per Unit does not  necessarily  reflect the
amount a Unitholder would receive if the Partnership  were liquidated,  and does
not  take  into  account   transaction   costs  relating  to  the  sale  of  the
Partnership's   properties,   which  would  reduce  the  amounts  available  for
distribution.  There can be no assurance that the actual value of a Unit was not
more or less than the Revised Deemed Net Asset Value Per Unit, or that the value
of a Unit will not increase or decrease.

                  The New Appraisal  Information was obtained in connection with
the General Partners'  consideration of a possible  settlement of the California
Action (as defined in paragraph 12 below).  The  following  table sets forth the
market  value of each of the  Partnership's  properties  as specified in the New
Appraisal  Information.  (In the case of joint  venture  investments,  the value
represents the Partnership's  proportionate interest in the joint venture. There
is no  discount  to  reflect  the fact  that  certain  real  estate in which the
Partnership   has  an  interest  is  held  by  joint  ventures  with  affiliated
partnerships  in which  the  Partnership  itself  does  not  have a  controlling
interest or the unilateral power to effect a sale of the entire property.)

</TABLE>

                  The  sum of the  appraised  value  of the  Partnership's  real
estate  plus the  Partnership's  net  current  assets at March 31,  1998  equals
$58,740,665, or $150.10 per Unit.

                  2. Secondary  market sales  activity for the Units,  including
privately  negotiated sales, has been limited. At present,  privately negotiated
sales and  sales  through  intermediaries  (E.G.,  through  the  trading  system
operated by American  Partnership  Board,  Inc.,  which publishes sell offers by
holders of Units) are the only means  available to a Unitholder  to liquidate an
investment  in Units  (other than the Offer and other  possible  tender  offers)
because  the Units are not  listed  or traded on any  exchange  or quoted on any
NASDAQ  list or  system.  According  to  Partnership  Spectrum,  an  independent
industry publication,  between December 1, 1997 and January 31, 1998, there were
671 Units traded in the secondary  market between a high of $109.50 per Unit and
a low of $84.00 per Unit, with a weighted average price of $93.89 per Unit. Such
prices do not take  into  account  commissions  and  other  transactional  costs
payable by sellers of Units  (which  typically  range  between 8% and 10% of the
reported selling price). In addition,  such prices do not reflect the prices per
Unit paid by an  affiliate of the General  Partners in that period  ranging from
$109.93  per Unit to  $124.00  per  Unit,  or the  $128.00  per Unit  paid by an
affiliate of the General Partners in early February 1998. See Item 6 below.

                  3. Three  tender  offers for Units  occurred  during  1996 and
1997.  Each  offer was for fewer  than 5% of the  outstanding  Units.  The offer
prices were $60.00 per Unit (in a June 1996 tender offer), $72.00 per Unit (in a
February  1997 tender  offer) and  $100.00  per Unit (in an October  1997 tender
offer).  These tender  offers have afforded only a modest amount of liquidity to
limited  partners,  and, in each case,  the General  Partners  recommended  that
limited partners reject the offer. In March 1998, another tender offer commenced
for fewer than 5% of the  outstanding  Units with an offer  price of $125.00 per
Unit. The General  Partners have  recommended  that the limited  partners reject
that offer.

                  4. During 1996 and 1997,  affiliates  of the General  Partners
purchased from Elm Investors LLC ("Elm"), in privately negotiated  transactions,
for an  aggregate of  $124,210,  an  aggregate of 1,500 Units (I.E.,  an average
price of $82.81 per Unit) the  General  Partners  believe Elm had  acquired,  at
least in part, pursuant to a tender offer in June 1996, in which Elm had offered
to purchase fewer than 5% of the  outstanding  Units for $60.00 per Unit.  These
purchases  of Units  were for  investment  purposes  and with a view to making a
profit. See the preceding paragraph and Item 6 below.

                  5. In March  1997,  KB Realty  Advisors,  Inc.  ("KB") made an
offer, subject to a number of conditions, to purchase all the real estate assets
of all three Partnerships for $141,000,000 in the aggregate.

                                      III-2

<PAGE>



If the offer by KB had been  accepted  and the  Partnerships  had  received  the
$141,000,000, the General Partners estimate that the Partnership's share of that
amount  would  have been  $43,594,737,  and,  after  payment  of taxes and other
expenses  required to be borne by the Partnership  under the KB offer (estimated
at 2% of the  purchase  price),  the  General  Partners  estimate  that  the net
proceeds of the transaction that would have been allocable to the  Partnerships'
limited partners would have been $40,586,700, or $109.17 per Unit. If, following
such a transaction,  the Partnership had been liquidated, and the $2,212,013 the
General  Partners  estimate  would  have  been  payable  by them to the  limited
partners  (see Item (b)(i) in Schedule I above) (the  "Excess Fee  Amount")  had
been paid, the General  Partners  estimate that the limited  partners would have
received $126.61 per Unit (including  amounts relating to the limited  partners'
share of the other net assets of the Partnership).  By comparison,  the per Unit
price in the Offer is $125.50, and the sum of the Revised Deemed Net Asset Value
Per Unit plus the per Unit value of the Excess Fee Amount is $156.05.

                  6. The General Partners are actively  considering a variety of
plans to enhance the value and  liquidity of the Units.  The plans have included
possible  conversion  of the  Partnership  into an  actively  traded real estate
investment   trust  (a   "Reorganization   Plan").   Although  the  terms  of  a
Reorganization  Plan have not been defined,  it is the present  intention of the
General  Partners that, if a  Reorganization  is effected,  the fees to them and
their  affiliates  from the  Partnership  would not increase from their existing
level (see Item  3(b)(i)  in the  Original  Schedule  14D-9),  and their  equity
interest in the  Partnership  as general  partners  would not increase  from the
existing  level.  The trading price for the  securities  that would be issued in
exchange  for the Units could be more or less than the trading  price  currently
available in the  secondary  market.  A  Reorganization  Plan would require as a
condition to its consummation,  among other things, the approval by holders of a
majority of the outstanding  Units.  There can be no assurance a  Reorganization
Plan, or any other plan, will actually be proposed by the General Partners,  or,
if proposed,  will be approved by holders of a majority of the outstanding Units
or consummated.  However,  if a  Reorganization  Plan is proposed by the General
Partners and subject to paragraph 7 below, the General partners expect that they
and their affiliates would vote all Units they own at the time in its favor, and
that the Purchaser and its affiliates  would vote all Units they own at the time
in its favor. At present, the General Partners and their affiliates beneficially
own, in the aggregate,  12.7% of the  outstanding  Units,  and the Purchaser has
advised that it and its affiliates  beneficially own, in the aggregate,  0.6% of
the outstanding  Units. If the Purchaser  acquires a substantial number of Units
in the Offer, the likelihood of approval of a Reorganization  Plan, if proposed,
would be enhanced.

                  7.  Unitholders  who tender  their Units will be giving up the
opportunity to participate in any potential benefits represented by ownership of
such Units,  including  participation  in possible  future  tender offers by the
Purchaser or its  affiliates,  possible  financings  of  Partnership  properties
resulting  in  possible  special  distributions  by  the  Partnership,  possible
appreciation in the value of the Units and  participation in any  reorganization
of  the  Partnership,  including  the  Reorganization  Plan,  or  resolution  or
disposition  of  the  litigation  described  in  paragraph  12  below.  In  that
connection,  the  General  Partners  have  determined  that,  prior to the first
anniversary  of the  completion  of the Offer,  the General  Partners  and their
affiliates will not solicit approval by the limited partners for, or consummate,
a  transaction,  or series of  related  transactions,  constituting  a  "roll-up
transaction"  (within the meaning of  Regulation  S-K,  Item 901),  other than a
conversion  of the  Partnership  into a stand-alone  (i.e.,  not part of another
entity or entities),  actively traded,  real estate investment trust pursuant to
Section  3(a)(10) of the Securities Act of 1933,  where the terms and conditions
of the  transaction,  or series of related  transactions,  including any related
tender offers for Units or any sale or financing of Partnership properties,  are
approved,  after a hearing  upon the  fairness of such terms and  conditions  at
which all limited partners have the right to appear,  by the court in connection
with a settlement of the litigation described in paragraph 12 below.

                  8. The agreement  among the  Purchaser  and  affiliates of the
General Partners  described in Item 3 in the Original  Schedule 14D-9 (which has
been amended to provide for indemnification by the

                                      III-3

<PAGE>



parties for information concerning themselves and their respective affiliates in
connection with the Offer and the offers for units of the other HEP Partnerships
and to provide that the  Purchaser and its  affiliates  are not required to vote
their Units in favor of any  proposal  in  contravention  of  paragraph 7 above)
creates certain  conflicts of interest for the General  Partners with respect to
the Offer.

                  9.  Unitholders  could,  as an alternative to tendering  their
Units,  propose a variety of  possible  actions,  including  liquidation  of the
Partnership or removal and replacement of the General Partners.

                  10.  Depending upon the number of Units  tendered  pursuant to
the Offer and whether  the  Purchaser  or its  affiliates,  on the one hand,  or
affiliates of the General  Partners,  on the other hand,  acquire Units from the
other  pursuant to the  agreement  described in Item 3 in the Original  Schedule
14D-9, the Purchaser or its affiliates, on the one hand, or the General Partners
or their  affiliates,  on the other  hand,  could be in a stronger  position  to
influence significantly all Partnership decisions on which Unitholders may vote,
including decisions regarding removal of the General Partners,  merger, sales of
assets and liquidation.  Accordingly,  (i)  non-tendering  Unitholders  could be
prevented  from taking  action they  desire  that the  Purchaser  or the General
Partners,  as the case may be,  oppose,  and (ii) the  Purchaser  or the General
Partners,  as  the  case  may  be,  may  be  able  to  take  action  opposed  by
non-tendering Unitholders.

                  11. Pursuant to the partnership agreement,  transfers of Units
that  would  cause a  termination  of the  Partnership  for  federal  income tax
purposes  (which  may occur when 50% or more of the Units are  transferred  in a
12-month period) are not permitted.  Depending upon the number of Units tendered
pursuant to the Offer,  sales of Units on the secondary  market for the 12-month
period  following  completion of the Offer may be limited.  The Partnership will
not process a request for transfer of Units during that 12- month period, if the
General  Partners  believe  the  transfer  may  cause  a  tax  termination.   In
determining  the  number of Units  subject  to the  Offer,  the  parties  to the
agreement  described  in  Item  3 in  the  Original  Schedule  14D-9  took  this
restriction into account to permit historical levels of transfers to occur after
consummation of the Offer without violating this restriction.

                  12.  In  May  1993,   limited  partners  in  the  Partnerships
commenced a class action (the  "California  Action") on behalf of all  investors
against  the HEP  General  Partners  and certain  related  persons and  entities
asserting various claims arising from alleged mismanagement of the Partnerships.
On November 30, 1995, the original plaintiffs and intervening plaintiffs filed a
consolidated   class  and  derivative   action   complaint  (the   "Consolidated
Complaint")  alleging various state law class and derivative  claims,  including
claims for breach of fiduciary duty;  breach of contract;  unfair and fraudulent
business  practices under  California  Bus. & Prof. Code ss. 17200;  negligence;
dissolution, accounting, receivership and removal of general partner; fraud; and
negligent  misrepresentation.  The Consolidated  Complaint alleges,  among other
things, that the HEP General Partners caused a waste of the Partnerships' assets
by  collecting  management  fees in lieu of pursuing a strategy to maximize  the
value of the investments  owned by the investors in the  Partnerships,  that the
HEP  General  Partners  breached  their  duty of  loyalty  and  due  care to the
investors by expropriating  management fees from the Partnerships without trying
to run the Partnerships for the purposes for which they were intended;  that the
HEP General  Partners  were acting  improperly  to entrench  themselves in their
position  of control  over the  Partnerships  and that their  actions  prevented
non-affiliated entities from making and completing tender offers to purchase HEP
Units; that, by refusing to seek the sale of the Partnerships'  properties,  the
HEP  General  Partners  diminished  the  value of the  investors'  equity in the
Partnerships;  that the HEP  General  Partners  took  heavily  overvalued  asset
management  fees;  and that HEP Units were sold and marketed  through the use of
false and misleading statements.

         In early 1996, the parties submitted a proposed settlement to the court
(the "Proposed  Settlement"),  which  contemplated a reorganization of the three
Partnerships  into a single  real  estate  investment  trust,  pursuant to which
approximately  85% of the shares of the real estate  investment trust would have
been

                                      III-4

<PAGE>



allocated to  investors  in the  aggregate  (assuming  each of the  Partnerships
participated in the  reorganization)  and  approximately 15% of the shares would
have been allocated to the HEP General Partners. As a consequence,  the Proposed
Settlement would, among other things, have approximately tripled the HEP General
Partners'  equity  interests in the  Partnerships.  In late 1996, the California
Department  of  Corporations  informed  the  Court  of its  conclusion  that the
Proposed  Settlement was unfair, and, in early 1997, the Court declined to grant
final  approval of the Proposed  Settlement  because the Court was not persuaded
that the Proposed Settlement was fair, adequate or reasonable as to the proposed
class.

         As set  forth  in Item 6  above,  although  the  General  Partners  are
actively  considering  a variety of plans to enhance the value and  liquidity of
the  Units,   including  a  possible   Reorganization   Plan,  the  terms  of  a
Reorganization  Plan  have  not been  defined.  Nonetheless,  it is the  present
intention of the General  Partners  that,  if a  Reorganization  Plan were to be
pursued, (a) the fees to them and their affiliates would not increase from their
existing level, and (b) unlike the Proposed Settlement, which would, among other
things,  have approximately  tripled the HEP General Partners' equity interests,
their equity  interests as general partners would not increase from the existing
level.

         The plaintiffs have filed an amended complaint, which generally asserts
the same claims as the earlier Consolidated Complaint but contains more detailed
factual assertions and eliminates some claims they had previously asserted.  The
HEP General Partners believe that the amended complaint was subject to challenge
on legal grounds and filed  demurrers  and a motion to strike.  In October 1997,
the Court granted  substantial  portions of the HEP General  Partners'  motions.
Thereafter,  the HEP General Partners served answers denying the allegations and
asserting numerous defenses.

         The  plaintiffs and the HEP General  Partners  recently have engaged in
discussions  relating  to  a  possible  settlement  of  the  California  Action,
including  discussions  regarding a possible  tender offer by the Partnership or
the General  Partners or their  affiliates  for Units at a price that may exceed
the price in the Offer.  There can be no assurance the parties will enter into a
settlement  agreement,  or that the  court  will  approve  any  such  settlement
agreement.

         The HEP  General  Partners  believe  each  of the  claims  asserted  is
meritless and intend to continue vigorously to defend the California Action. The
partnership  agreement  provides for  indemnification of the General Partner and
their  affiliates  in  certain  circumstances.  The  Partnership  has  agreed to
reimburse  the General  Partners for the actual costs  incurred in defending the
California  Action  and the costs of  preparing  settlement  materials.  Through
December 31, 1997,  the General  Partners had billed the  Partnership a total of
$1,039,511 for these costs, of which $824,511 was paid in February 1997.

PARTNERSHIP  UNITS OF HIGH EQUITY  PARTNERS  L.P. -- SERIES 88,  DATED MARCH 12,
1998  (AS  AMENDED  AND  SUPPLEMENTED  THROUGH  JULY  1,  1998,  THE  "OFFER  TO
PURCHASE").

         The undersigned hereby tenders to Olympia  Investors,  L.P., a Delaware
limited partnership (the "Purchaser"),  the number of the undersigned's units of
limited  partnership  interest specified in the signature box (together with the
Certificates,  "Units") in High Equity  Partners  L.P.  --Series  88, a Delaware
limited partnership (the "Partnership"),  at a price of $125.50 per Unit, net to
the seller in cash, without interest, less the amount of distributions per Unit,
if any (other than distributions of Adjusted Cash from Operations, as defined in
the Partnership  Agreement),  made by the Partnership from the date of the Offer
to Purchase until the Payment Date, upon the terms and subject to the conditions
set forth in the Offer to Purchase, receipt of which is hereby acknowledged, and
in this Assignment of Partnership Interest (which, together with any supplements
or amendments,  collectively constitute the "Offer"). The Purchaser reserves the
right to  transfer or assign,  in whole or from time to time in part,  to one or
more persons,  the right to purchase Units tendered  pursuant to the Offer,  but
any  such  transfer  or  assignment  will  not  relieve  the  Purchaser  of  its
obligations  under the  Offer or  prejudice  the  rights  of  tendering  Limited
Partners to receive payment for Units validly  tendered and accepted for payment
pursuant  to the Offer.  Limited  Partners  who tender  their  Units will not be
obligated to pay any commissions or Partnership transfer fees in connection with
such tender.

         The undersigned  understands that if more than 55,760 Units are validly
tendered  prior to or on the  Expiration  Date and not properly  withdrawn,  the
Purchaser will, upon the terms of the Offer, accept for payment from among those
tendered  Units  55,760  Units on a pro rata basis  based upon the number of the
tendered Units with  adjustments to avoid purchases of certain  fractional Units
and subject to the transfer requirements of the Partnership Agreement.

         Subject to and effective upon acceptance for payment of and payment for
the Units tendered hereby, the undersigned hereby sells,  assigns, and transfers
to or upon the order of the  Purchaser all right,  title,  proxy and interest in
and to all of the Units tendered  hereby  (including the related  Certificates),
including,  without limitation, all rights in, and claims to, any voting rights,
rights to be substituted as a Limited  Partner of the  Partnership,  Partnership
profits  and  losses,  cash  distributions  and  other  benefits  of any  nature
whatsoever  distributable or allocable or otherwise to such tendered Units under
the  Partnership  Agreement;  provided,  that if proration of tendered  Units is
required as described in Section 1 of the Offer to Purchase,  this Assignment of
Partnership  Interest  shall be effective to transfer to the Purchaser only that
number  of the  undersigned's  Units as is  accepted  for  payment  and  thereby
purchased by the Purchaser. The undersigned understands that upon acceptance for
payment of and payment for the Units tendered by the undersigned,  the Purchaser
will seek admission to the Partnership as a Limited Partner in substitution  for
the  undersigned  as to all Units  tendered  by the  undersigned.  If,  however,
proration of tendered  Units is required and as a result the  Purchaser  accepts
for payment  and  thereby  purchases  less than all of the  undersigned's  Units
tendered  hereby,  the  undersigned  may  continue to be a Limited  Partner with
respect  to  Units  tendered  by the  undersigned  that  are not  purchased.  By
executing  and  delivering   this  Assignment  of  Partnership   Interest,   the
undersigned,  being a tendering Limited Partner, expressly intends the Purchaser
to become a Limited Partner.


<PAGE>



         The undersigned understands and hereby acknowledges and agrees that the
Purchaser  shall  be  entitled  to  (i)  deduct  from  the  Purchase  Price  all
distributions  of cash or  other  property  from  the  Partnership  (other  than
distributions of Adjusted Cash from Operations)  attributable to the transferred
Units that are made on or after March 12,  1998,  without  regard to whether the
record date for any such  distribution  may be a date after or prior to the date
of transfer,  and (ii) receive all Partnership  distributions  after the Payment
Date.

         By executing and delivering this Assignment of Partnership  Interest, a
tendering  Limited  Partner  irrevocably  appoints  the  Purchaser,  its general
partner and any  designees of the  Purchaser and of each of them as such Limited
Partner's proxies,  with full power of substitution,  to the full extent of such
Limited  Partner's  rights with  respect to the Units  tendered by such  Limited
Partner and accepted for payment by the Purchaser including, without limitation,
to deliver such Units and transfer  ownership of such Units on the Partnership's
books  maintained  by the general  partners of the  Partnership  and to become a
substituted  Limited Partner and to receive all benefits and otherwise  exercise
all rights of beneficial ownership of such Units and as a Limited Partner of the
Partnership,  all in  accordance  with the terms of the Offer.  All such proxies
shall be  considered  irrevocable  and coupled  with an interest in the tendered
Units. Such appointment will be effective when, and only to the extent that, the
Purchaser  accepts  such Units for  payment.  Upon such  acceptance  for payment
pursuant to the Offer,  all prior  proxies  given by such  Limited  Partner with
respect to such Units will be revoked without further action,  and no subsequent
proxies may be given nor any subsequent  written consent executed (and, if given
or executed, will not be deemed effective).  The Purchaser,  its general partner
and any  designees of the  Purchaser  will,  with respect to the Units for which
such  appointment  is  effective,  be empowered to exercise all voting and other
rights of such Limited  Partner as they in their sole discretion may deem proper
at any meeting of Limited  Partners or any adjournment or postponement  thereof,
by written  consent in lieu of any such meeting or otherwise.  The Purchaser may
assign such proxy to any person with or without assigning the related Units with
respect to which such proxy was  granted.  The  Purchaser  reserves the right to
require that,  in order for a Unit to be deemed  validly  tendered,  immediately
upon the  Purchaser's  payment  for such  Unit,  the  Purchaser  must be able to
exercise  full  voting  rights with  respect to such Unit and other  securities,
including voting at any meeting of Limited Partners.

         By executing and delivering the Assignment of Partnership  Interest,  a
tendering  Limited  Partner  also  irrevocably   constitutes  and  appoints  the
Purchaser, its general partner and any designees of the Purchaser as the Limited
Partner's  attorneys-in-fact,  each with full power of  substitution to the full
extent of the Limited Partner's rights with respect to the Units tendered by the
Limited Partner and accepted for payment by the Purchaser. Such appointment will
be  effective  when,  and only to the extent  that,  the  Purchaser  accepts the
tendered Units for payment.  Upon such acceptance for payment,  all prior powers
of attorney  granted by the  Limited  Partner  with  respect to such Units will,
without further action, be revoked,  and no subsequent powers of attorney may be
granted (and if granted will not be effective).  Pursuant to such appointment as
attorneys-in-fact,  the Purchaser,  its general partner and any designees of the
Purchaser each will have the power,  among other things, (i) to seek to transfer
ownership of such Units on the Partnership's  books (and execute and deliver any
accompanying  evidences  of  transfer  and  authenticity  any of them  may  deem
necessary or appropriate in connection therewith, including, without limitation,
any  documents  or  instruments  required to be executed  under a  "Transferor's
(Seller's)  Application  for Transfer"  created by the NASD, if required),  (ii)
upon receipt by the Depositary (as the tendering Limited Partner's agent) of the
Purchase Price, to receive any and all  distributions  made by the  Partnership,
and to receive all benefits  and  otherwise  exercise  all rights of  beneficial
ownership  of such Units in  accordance  with the terms of the  Offer,  (iii) to
execute and deliver to the Partnership  and/or its general  partners a change of
address  form   instructing   the   Partnership  to  send  any  and  all  future
distributions  to which the  Purchaser is entitled  pursuant to the terms of the
Offer,  in respect of tendered Units to the address  specified in such form, and
(iv) to endorse any check  payable to or upon the order of such Limited  Partner
representing a distribution  to which the Purchaser is entitled  pursuant to the
terms of the Offer, in each case on behalf of the tendering Limited Partner.  If
legal title to the Units is held through an IRA or KEOGH or similar account, the
Limited Partner understands that this Assignment of Partnership Interest must be
signed by the  custodian  of such IRA or KEOGH and the  Limited  Partner  hereby
authorizes  and  directs  the  custodian  of such IRA or KEOGH to  confirm  this
Assignment of Partnership Interest. This Power of Attorney shall not be affected
by the subsequent  mental  disability of the Limited Partner,  and the Purchaser
shall not be required to post bond in any nature in  connection  with this Power
of Attorney.  The Purchaser may assign such Power of Attorney to any person with
or without  assigning  the  related  Units  with  respect to which such Power of
Attorney was granted.

         The  undersigned  hereby  represents and warrants that the  undersigned
owns the Units  tendered  hereby  and has full  power and  authority  to validly
tender,  sell,  assign and transfer the Units tendered  hereby and that when the
same are accepted for payment by the Purchaser, the Purchaser will acquire good,
marketable  and  unencumbered  title  thereto,  free  and  clear  of all  liens,
restrictions,  charges,  encumbrances,  conditional  sales  agreements  or other
obligations relating to the sale or transfer thereof, and such Units will not be
subject to any adverse claims and that the transfer and assignment  contemplated
herein  are  in  compliance  with  all  applicable  laws  and  regulations.  The
undersigned  further  represents and warrants that the  undersigned is a "United
States person",  as defined in section  7701(a)(30) of the Internal Revenue Code
of 1986, as amended (the "Code"),  or if the  undersigned is not a United States
person,  the undersigned  does not own beneficially or of record more than 5% of
the outstanding  Units.  Upon request,  the undersigned will execute and deliver
any  additional  documents  deemed  by the  Depositary  or the  Purchaser  to be
necessary  or desirable  to complete  the  assignment,  transfer and purchase of
Units  tendered  hereby and  otherwise  in order to complete  the  transactions,
transfers and admissions to the Partnership contemplated herein.

         The  undersigned  understands  that a tender of Units  pursuant  to the
procedures  described  in  Section  3 of  the  Offer  to  Purchase  and  in  the
Instructions  hereto will constitute a binding agreement between the undersigned
and the Purchaser upon the terms and subject to the conditions of the Offer. All
authority  herein conferred or agreed to be conferred shall survive the death or
incapacity of the undersigned,  and any obligation of the undersigned  hereunder
shall be  binding  upon the  heirs,  personal  representatives,  successors  and
assigns  of the  undersigned.  Except  as stated in the  Offer,  this  tender is
irrevocable.

         The undersigned  recognizes that under certain  circumstances set forth
in the Offer to  Purchase,  the  Purchaser  may not be  required  to accept  for
payment  any of the  Units  tendered  hereby.  If any  tendered  Units  are  not
purchased  for any reason,  the  Assignment  of  Partnership  Interest  shall be
effective to transfer to the Purchaser  only that number of Units as is accepted
and thereby purchased by the Purchaser,  and the Certificates (or, if necessary,
new certificates) representing such unpurchased Units shall be returned.

         Upon acceptance of Units by the Purchaser,  the Purchaser  agrees to be
bound by all of the terms and provisions of the Partnership Agreement.

         For IRA  custodial  accounts,  the  beneficial  owner should return the
executed  Assignment of  Partnership  Interest to the Depositary as specified in
Instruction  1 herein.  Such  Assignment  of  Partnership  Interest will then be
forwarded by the  Depositary  to the custodian for  additional  execution.  Such
Assignment of Partnership  Interest will not be considered  duly completed until
after it has been executed by the custodian.

         If any tendered  Units are  registered in different  names,  it will be
necessary  to  complete,   sign  and  submit  as  many  separate  Assignment  of
Partnership Interests as there are different registrations of certificates.

         ALL  SIGNATURES  ON THE  ASSIGNMENT  OF  PARTNERSHIP  INTEREST  MUST BE
MEDALLION  GUARANTEED BY A COMMERCIAL BANK, SAVINGS BANK, CREDIT UNION,  SAVINGS

                  ALL SIGNATURES MUST BE MEDALLION GUARANTEED.

  4. U.S. PERSONS.  A Limited Partner who or which is a United States citizen or
a resident alien individual, a domestic corporation,  a domestic partnership,  a
domestic trust or a domestic estate  (collectively,  "United States persons") as
those terms are defined in the Code and Income Tax  Regulations,  should  follow
the instructions with respect to certifying Boxes A and B.

         TAXPAYER  IDENTIFICATION  NUMBER.  To  avoid  31%  federal  income  tax
withholding, the Limited Partner or other payee must provide the Depositary with
the Limited  Partner's  correct TIN in the blanks  provided  for that purpose in
Boxes A and B.  In the  case  of an  individual  person,  such  person's  social
security number is his or her TIN.

         WHEN  DETERMINING  THE TIN TO BE  FURNISHED,  PLEASE  NOTE:  Individual
accounts  should reflect their own TIN; joint accounts should reflect the TIN of
the person whose name  appears  first;  trust  accounts  should  reflect the TIN
assigned  to the Trust;  custodial  accounts  for the  benefit of minors  should
reflect the TIN of the minor;  corporations or other  businesses  should reflect
the TIN assigned to that entity.

         SUBSTITUTE FORM W-9 - BOX A. Each tendering Limited Partner is required
to provide  the  Depositary  with a correct  TIN on  Substitute  Form W-9 and to
certify,  under  penalties of perjury,  that (i) the TIN provided on  Substitute
Form W-9 is correct (or that such Limited  Partner is awaiting a TIN),  and (ii)
the Limited  Partner either (a) is exempt from backup  withholding,  (b) has not
been  notified  by the IRS  that  the  Limited  Partner  is  subject  to  backup
withholding as a result of a failure to report all interest or dividends, or (c)
has been  notified by the IRS that the Limited  Partner is no longer  subject to
backup  withholding.  Failure to provide the information on the form may subject
the  tendering  Limited  Partner to 31% federal  income tax  withholding  on the
payments  made to the  Limited  Partner  or other  payee  with  respect to Units
purchased pursuant to the Offer.

         The box in Box A, Part 2 of the form may be  checked  if the  tendering
Limited  Partner  has not been issued a TIN and has applied for a TIN or intends
to apply for a TIN in the near future.  If the box in Part 2 is checked,  backup
withholding,  if applicable,  will begin 7 days after the Depositary receives an
Awaiting TIN  Certification and will continue until the Limited Partner's TIN is
provided  to the  Depositary.  If within  60 days the  Depositary  receives  the
Limited  Partner's TIN on a new IRS Form W-9 or copy of the Substitute  Form W-9
provided  above,  the Depositary will return amounts  withheld  through the date
such IRS Form W-9 or Substitute Form W-9 is received.

         DO NOT CHECK THE BOX IN BOX A, PART 3 UNLESS YOU HAVE BEEN  NOTIFIED BY
THE IRS THAT YOU ARE SUBJECT TO BACKUP WITHHOLDING.

         FIRPTA  AFFIDAVIT  - BOX  B.  To  avoid  potential  withholding  of tax
pursuant to Section  1445 of the Code in an amount  equal to 10% of the purchase
price  for  Units  purchased  pursuant  to the  Offer,  plus the  amount  of any
liabilities of the Partnership allocable to such Units, each Limited Partner who
or which is a United States person must complete the FIRPTA  Affidavit  stating,
under  penalties of perjury,  such Limited  Partner's TIN and address,  and that
such Limited Partner is not a foreign person. Tax withheld under Section 1445 of
the Code is not an additional  tax. If withholding  results in an overpayment of
tax, a refund may be obtained from the IRS.  CHECK THE BOX IN BOX B, PART 1 ONLY
IF YOU ARE NOT A U.S. PERSON AS DESCRIBED THEREIN.

  5. FOREIGN  PERSONS.  In order for a Limited  Partner who is a foreign  person
(i.e.,  not a United States person as defined in Instruction 4 above) to qualify
as exempt  from 31%  backup  withholding,  such  foreign  Limited  Partner  must
complete and deliver to the Depositary, along with the Assignment of Partnership
Interest, Substitute Form W-8 which can be obtained from the Information Agent.

  6. CONDITIONAL TENDERS. No alternative, conditional or contingent tenders will
be accepted.

  7. NUMBER OF UNITS TENDERED; MINIMUM TENDERS; PARTIAL TENDERS.  ASSIGNMENTS OF
PARTNERSHIP  INTEREST WHICH HAVE BEEN DULY EXECUTED,  BUT WHERE NO INDICATION IS
MARKED IN THE "NUMBER OF UNITS  TENDERED"  COLUMN IN THE SIGNATURE BOX, SHALL BE
DEEMED TO HAVE TENDERED ALL UNITS PURSUANT TO THE OFFER.  ALL UNITS  REPRESENTED
BY CERTIFICATES DELIVERED TO THE DEPOSITARY WILL BE DEEMED TO HAVE BEEN TENDERED
UNLESS  OTHERWISE  INDICATED.  If fewer  than  all the  Units  evidenced  by any
Certificate  submitted are to be tendered,  new Certificate(s) for the remainder
of the Units that were evidenced by the old  Certificate(s)  will be sent to the
tendering  Limited  Partner as soon as  practicable  after the expiration of the
Offer.  A Limited  Partner  may  tender  any or all of the  Units  owned by that
Limited  Partner,  provided,  however,  in order for the transfer to be valid, a
minimum of 10 Units or, if Units are tendered by an IRA or KEOGH, 4 Units,  must
be sold pursuant to the Offer and provided  further that a Limited  Partner must
sell all of his Units if he would otherwise retain less than 10 Units or, in the
case of an IRA or KEOGH, 4 Units (8 Units for residents of Iowa).  No fractional
Units will be purchased  (except from a Limited  Partner who is tendering all of
the Units owned by that Limited Partner).  All tendering  Limited  Partners,  by
execution of the  Assignment of  Partnership  Interest (or  facsimile  thereof),
waive any right to  receive  any  notice of the  acceptance  of their  Units for
payment.

  8.  CERTIFICATES.  Anything  herein to the contrary  notwithstanding,  Limited
Partners should furnish Certificates evidencing tendered Units to the Depositary
only if available. It is not necessary to furnish such Certificates in order for
your tender to be valid.

  9. ASSIGNEE  STATUS.  Assignees must provide  documentation  to the Depositary
which demonstrates,  to the satisfaction of the Purchaser,  such person's status
as an assignee.



<PAGE>


  10.  VALIDITY OF ASSIGNMENT OF PARTNERSHIP  INTEREST.  All questions as to the
validity,  form,  eligibility  (including  time of receipt)  and  acceptance  of
Assignment of Partnership  Interest will be determined by the Purchaser and such
determination will be final and binding.  The Purchaser's  interpretation of the
terms  and  conditions  of the  Offer  (including  these  Instructions  for  the
Assignment  of  Partnership  Interest)  also  will be  final  and  binding.  The
Purchaser  will have the right to waive any  irregularities  or conditions as to
the manner of tendering.  And any irregularities in connection with tenders must
be cured within such time as the Purchaser shall determine unless waived by it.

         The  Assignment  of  Partnership  Interest will not be valid unless and
until any irregularities have been cured or waived.  Neither the Purchaser,  the
Depositary nor the Information  Agent are under any duty to give notification of
any defects in an Assignment of Partnership Interest and will incur no liability
for failure to give such notification.

  11. REQUESTS FOR ASSISTANCE AND ADDITIONAL  COPIES.  Questions or requests for
assistance may be directed to the Information Agent, Beacon Hill Partners,  Inc.
at (212) 843-8500  (collect) or (800) 301-8755 (toll free).  Copies of the Offer
to Purchase and the Assignment of Partnership  Interest may be obtained from the
Information Agent by calling either number.

  12. INADEQUATE  SPACE. If the space provided herein is inadequate,  additional
information may be provided on a separate schedule signed and attached hereto.

         IMPORTANT:  A  PROPERLY  COMPLETED  AND  DULY  EXECUTED  ASSIGNMENT  OF
PARTNERSHIP INTEREST (ALONG WITH AND ANY AND ALL CERTIFICATES,  AND ANY REQUIRED
SIGNATURE  GUARANTEES AND ANY OTHER REQUIRED  DOCUMENTS) MUST BE RECEIVED BY THE
DEPOSITARY  ON OR PRIOR TO 5:00  P.M.,  NEW YORK CITY  TIME,  ON JULY 17,  1998,
UNLESS EXTENDED.

                            IMPORTANT TAX INFORMATION

         Under federal income tax law, in order to prevent backup withholding on
amounts  payable to a Limited  Partner  whose  tendered  Units are  accepted for
payment,  such Limited  Partner is required to provide the Depositary  with such
Limited  Partner's  correct  TIN on  Substitute  Form  W-9  above  or  otherwise
establish a basis for exemption  from backup  withholding.  If the Depositary is
not provided  with the correct  TIN,  the Limited  Partner or other payee may be
subject to penalties imposed by the IRS. In addition,  payments that are made to
such Limited Partner or other payee with respect to Units purchased  pursuant to
the Offer may be subject to backup withholding.

         Certain Limited Partners (including, among others, all corporations and
certain  foreign  persons)  are not  subject  to these  backup  withholding  and
reporting  requirements.  Exempt Limited  Partners  should indicate their exempt
status on  Substitute  Form W-9. In order for a foreign  person to qualify as an
exempt  recipient,  that  Limited  Partner  must  deliver  to the  Depositary  a
Substitute  Form W-8,  signed  under  penalties  of perjury,  attesting  to that
Limited Partner's exempt status.

         If backup withholding  applies,  the Depositary is required to withhold
31% of any  reportable  payments  made to the  Limited  Partner or other  payee.
Backup  withholding  is not an additional  tax.  Rather,  the federal income tax
liability of persons subject to backup withholding will be reduced by the amount
of tax withheld. If withholding results in an overpayment of taxes, a refund may
be obtained from the IRS.

                                 Amendment No. 2
                                       to
                                    Agreement
                               dated March 6, 1998

                  This Amendment No. 2 (the  "Amendment"),  dated as of June 29,
1998, amends the agreement, dated March 6, 1998 (the "Agreement") and as amended
by Amendment No. 1 thereto,  dated as of May 20, 1998 ("Amendment No. 1"), among
Presidio  Capital Corp.,  a corporation  organized in the British Virgin Islands
("Presidio"),   American  Real  Estate   Holdings,   L.P.,  a  Delaware  limited
partnership ("AREH") and Olympia Investors, L.P., a Delaware limited partnership
("Olympia").  Capitalized  terms used herein and not otherwise defined will have
the meanings ascribed to them in the Agreement.

                  The parties agree as follows:

                  1. The following proviso is hereby added to the end of Section
5 of the Agreement:

         "; provided, however, that AREH shall have no obligation to cause Units
         of a Partnership to be voted in favor of any proposal otherwise covered
         by this  Section  5 if such  proposal  (a) is made  prior to the  first
         anniversary of the completion of the Offer relating to such Partnership
         and (b)  relates to a  transaction  or series of  related  transactions
         constituting a "roll-up  transaction" (within the meaning of Regulation
         S-K,  Item  901),  other  than a proposal  for the  conversion  of such
         Partnership  into a stand-alone  (i.e.,  not part of another  entity or
         entities),  actively traded,  real estate  investment trust pursuant to
         Section  3(a)(10) of the  Securities  Act of 1933,  where the terms and
         conditions  of the  transaction,  or  series of  related  transactions,
         including  any related  tender offer for Units or any sale or financing
         of  Partnership  properties,  are  approved,  after a hearing  upon the
         fairness of such terms and  conditions  at which all  limited  partners
         have the right to appear,  by the court in connection with a settlement
         of the  litigation  described in Item 4,  paragraph 12 of the Schedules
         14D-9  filed by HEP 85 and HEP 88 in  connection  with the  Offers  for
         Units of those Partnerships and in Item 4, paragraph 11 of the Schedule
         14D-9  filed by HEP 86 in  connection  with the  Offer for Units of HEP
         86."
