NOTE 1.
- ------

McNeil  Real  Estate  Fund  XX,  L.P.  (the  "Partnership"),  formerly  known as
Southmark  Income  Investors,  Ltd., was organized on July 19, 1984 as a limited
partnership  under the  provisions of the  California  Revised  Uniform  Limited

(the "General Partner"), a Delaware limited partnership,  an affiliate of Robert
A. McNeil  ("McNeil").  The principal  place of business for the Partnership and
the General Partner is 13760 Noel Road, Suite 700, Dallas, Texas 75240.

In the opinion of management,  the financial  statements reflect all adjustments
necessary for a fair  presentation of the Partnership's  financial  position and
results  of  operations.  All  adjustments  were of a normal  recurring  nature.
However,  the results of operations for the nine months ended September 30, 1995
are not necessarily indicative of the results to be expected for the year ending
December 31, 1995.

NOTE 2.
- ------

The  financial  statements  should  be read in  conjunction  with the  financial
statements  contained in the  Partnership's  Annual  Report on Form 10-K for the

NOTE 3.
- ------

The  Partnership  pays property  management fees equal to 5% of the gross rental
receipts for its properties to McNeil Real Estate Management,  Inc.  ("McREMI"),
an affiliate of the General Partner, for providing property management services.

The  Partnership  reimburses  McREMI  for  its  costs,  including  overhead,  of
administering the Partnership's affairs.

The  Partnership  is paying an asset  management  fee  which is  payable  to the
General  Partner.  Through 1999, the asset management fee is calculated as 1% of
the  Partnership's  tangible asset value.  Tangible asset value is determined by
using the greater of (i) an amount calculated by applying a capitalization  rate
of 9% to the annualized net operating  income of each property,  (ii) a value of
$10,000 per apartment  unit or (iii) on 1130  Sacramento,  the net book value of
the  property  is used to arrive  at the  property  tangible  asset  value.  The
property  tangible  asset  value is then  added to the book  value of all  other
assets excluding intangible items.
The fee percentage decreases subsequent to 1999.

Compensation  and  reimbursements  paid to or  accrued  for the  benefit  of the
General Partner and its affiliates are as follows:

                                                                                  Nine Months Ended

In May 1994,  the Idlewood  Nursing Home mortgage loan  investment was modified,
extending  the maturity date to March 1999 and reducing the interest rate on the
loan from 12% to 8.5%.  Unpaid  accrued  interest of $82,566 for  November  1993

no longer considered  interest.  Monthly payments of principal and interest were
reduced from $25,067 to $17,286  beginning  April 1, 1994. In February 1995, the
Idlewood Nursing Home mortgage loan investment was again modified.  The interest
rate remained at 8.5% and the maturity date was changed to February 1, 1998. The
borrower paid the Partnership  $33,200 in cash at the date of  modification  and
the  monthly  payments  on the loan  were  changed  such  that  cash  flow  from
operations of the property, with a minimum payment of $9,130, are due monthly.

In February  1995,  the  Lakeland  Nursing Home  mortgage  loan  investment  was
modified  extending the maturity date to February 1, 1999. The interest rate and
monthly  payment amount remain the same.  The borrower paid a $25,941  extension
fee which the Partnership recorded as a deferred gain.

ITEM 2.       MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
- ------        ---------------------------------------------------------------
              RESULTS OF OPERATIONS
              ---------------------

FINANCIAL CONDITION
- -------------------

There has been no  significant  change in the  operations  of  Sterling  Springs
Apartments or 1130 Sacramento Condominiums since December 31, 1994.

The Partnership reported a net loss of $17,803 for the first nine months of 1995
as compared to net income of $185,290  for the same period in 1994.  Revenues in
1995 were $1,428,307 as compared to $1,368,008 in 1994, while expenses increased
to $1,446,110 from $1,182,718.

Net cash provided by operating activities was $350,823 for the nine months ended
September  30, 1995, a change from the  $328,011  provided  during the same nine
month period in 1994. The Partnership expended $78,600 for capital improvements,
made $36,065 in principal  payments on its mortgage note payable,  and collected
$105,471 of principal  on mortgage  loan  investments.  After  distributions  of
$250,001 to the limited partners,  cash and cash equivalents  totaled $3,825,648
at  September  30,  1995, a net increase of $91,628 from the balance at December
31, 1994.

RESULTS OF OPERATIONS
- ---------------------

Revenue:

Total  revenue  increased  by $28,412  and  $60,299 for the three and nine month
periods ended September 30, 1995, respectively,  as compared to the same periods
in 1994.  The  increase  was due to an  increase  in  rental  revenue  and other
interest  income,  partially offset by a decrease in interest income on mortgage
loan investments, as discussed below.

Rental  revenue for the three and nine month  periods  ended  September 30, 1995
increased by $31,807 and $141,509, respectively, as compared to the same periods
in 1994.  The  increase  was  partially  due to an increase  in rental  rates at
Sterling Springs  Apartments in February 1995. Also contributing to the increase
in rental revenue was the increase in occupancy at 1130 Sacramento Condominiums.
Although  construction  of the building was completed in early 1994,  two of the
four units were not leased until the third quarter of 1994.

Interest income on mortgage loan  investments  decreased by $16,067 and $138,518
for the three  and nine  months  ended  September  30,  1995,  respectively,  as
compared to the same  periods in 1994 due to the  modification  of the  Idlewood
Nursing Home mortgage loan investment in February 1995 (See Item 1 - Note 4). In
accordance with Statement of Financial  Accounting Standards No. 114 "Accounting
by Creditors  for  Impairment  of a Loan" ("SFAS  114"),  which the  Partnership
adopted in 1994, the Partnership  has ceased  accruing  interest on the loan and
all payments received are recorded as a reduction of principal.

Other  interest  income  earned  on  short-term  investments  of cash  and  cash
equivalents  increased  by  $12,672  and  $57,308  for the three and nine  month
periods ended  September 30, 1995,  respectively,  as compared to the respective
periods in 1994.  The increase  was mainly due to an increase in interest  rates
earned on invested cash during the first nine months of 1995.

Expenses:

Total  expenses for the three and nine month  periods  ended  September 30, 1995
increased by $158,382 and $263,392,  respectively, as compared to the respective
periods in 1994.  The  increase  was mainly due to an  increase  in general  and
administrative expenses, as discussed below.

Depreciation  expense  increased  by $12,022  and $39,809 for the three and nine
months ended September 30, 1995,  respectively,  as compared to the same periods
in 1994. The increase was primarily due to the addition of  depreciable  capital
improvements at Sterling Springs Apartments and 1130 Sacramento Condominiums.

Personnel  costs  increased  by $2,898 and $21,269 for the three and nine months
ended September 30, 1995, respectively, as compared to the respective periods in
1994.  The increase  was due to an increase in bonuses paid at Sterling  Springs
and 1130 Sacramento, the result of an increase in the overall performance of the
properties in the first quarter of 1995.

Property  management  fees increased by $1,879 in the three months and by $7,661
in the nine months  ended  September  30,  1995,  in relation to the  comparable
periods in 1994, due to an increase in gross rental receipts,  on which the fees
are based, at 1130 Sacramento Condominiums and Sterling Springs Apartments.

Other property  operating  expenses  decreased by $5,105 and increased by $8,749
for the three  and nine  months  ended  September  30,  1995,  respectively,  as
compared to the same periods in 1994. The overall  increase was mainly due to an
increase in property insurance costs in the first half of 1995.

General and  administrative  expenses increased by $141,782 and $151,596 for the
three and nine month periods ended September 30, 1995, respectively, as compared
to  the  respective  periods  in  1994.  The  increase  was  mainly  due  to the
Partnership incurring approximately $118,000 of costs relating to evaluation and
dissemination of information  regarding an unsolicited tender offer as discussed
in Item 5 - Other Information. In addition, there was an increase in legal fees,
the result of the Idlewood and Lakeland note modifications.

LIQUIDITY AND CAPITAL RESOURCES
- -------------------------------

The Partnership  generated  $350,823 through operating  activities for the first
nine months of 1995 as  compared to $328,011  for the first nine months of 1994.
The increase in 1995 was mainly due to an increase in cash received from tenants
(see discussion of increase in rental revenue above).

The Partnership  expended  $78,600 and $162,879 for capital  improvements to its
properties  in the first nine  months of 1995 and 1994,  respectively.  The 1994
amount  includes  improvements  to 1130  Sacramento for which  construction  was
completed early in 1994.

The Partnership collected $105,471 of principal on its mortgage loan investments
in the first nine months of 1995 as compared  to $33,986  collected  in the same
period in 1994.  As  previously  discussed,  in  accordance  with SFAS 114,  all
payments  received on the Idlewood  Nursing Home mortgage loan  investment  have
been recorded as a reduction of principal in 1995.

Short-term liquidity:
- --------------------

At  September  30,  1995,  the  Partnership  held cash and cash  equivalents  of
$3,825,648.  This balance provides a reasonable level of working capital for the
Partnerships immediate needs in operating its properties.

In 1995,  operations of Sterling  Springs  Apartments  and 1130  Sacramento  are
expected  to  provide  sufficient  positive  cash  flow for  normal  operations.
Management  will perform  routine  repairs and  maintenance on the properties to
preserve  and  enhance  their  value  and  competitiveness  in the  market.  The
Partnership has budgeted to spend approximately  $86,000 on capital improvements
to its  properties in 1995,  which are expected to be funded from  operations of
the properties.

For 1995,  management  expects that cash from  operations of its  properties and
principal and interest collections on the mortgage loan investments,  along with
the  present  balance  of  cash  and  cash  equivalents  held,  will  allow  the
Partnership to meet its obligations as they come due.

At the present time, the Partnership  anticipates  making  distributions  to the
limited partners in the foreseeable  future.  Management is currently  reviewing
cash requirements to determine the amount and timing of such distributions.

Long-term liquidity:
- -------------------

Only one property,  Sterling  Springs  Apartments,  is encumbered  with mortgage
debt. The mortgage on this property is not due until 2003.

In the event that the Partnership acquires ownership of other properties through
foreclosure, the cash and cash equivalent balances presently held will provide a
source for the maintenance and improvement of the properties. Because the timing
and number of  properties  which may be  foreclosed  is  uncertain,  there is no
assurance that the balances presently held will be sufficient for needed capital
improvements.  At  present,  there are no  commitments  nor any known  needs for
improvements to the properties securing the Partnership's loans. The Partnership
has no existing lines of credit from outside sources.

The General  Partner has  established a revolving  credit facility not to exceed
$5,000,000 in the aggregate  which is available on a "first-come,  first-served"
basis  to  the  Partnership  and  other  affiliated  partnerships,   if  certain
conditions are met.  Borrowings  under the facility may be used to fund deferred
maintenance,  refinancing  obligations  and working  capital needs.  There is no
assurance that the Partnership will receive any funds under the facility because
no amounts are  reserved for any  particular  partnership.  As of September  30,
1995,  $2,362,004 remained available for borrowing under the facility;  however,
additional  funds could become  available as other  partnerships  repay existing
borrowings.

Another possible source of funds is the sale of the Partnership's  mortgage loan
investments or properties securing the Partnership's  mortgage loans. Such sales
are  possibilities  only,  and  since  the  Partnership  does  not  control  the
properties  securing  its  loans,  sales of those  properties  may occur only if
initiated by the  borrower or in the event of  foreclosure  by the  Partnership.
There is no  assurance  that any sales can be  contracted  or closed to coincide
with the  Partnership's  future cash needs.  For the long term, the  Partnership
will  remain  dependent  on  operations  of the  properties  it  owns  or of the
properties securing its loans as the primary source of debt repayment, until the
properties can be sold.






                           PART II. OTHER INFORMATION


ITEM 1.      LEGAL PROCEEDINGS
- ------       -----------------

1) HCW Pension Real Estate Fund, Ltd. et al. v. Ernst & Young, BDO Seidman et al
(Case  #92-06560-A).  This suit was filed on behalf of the Partnership and other
affiliated partnerships (the "Affiliated  Partnerships") on May 26, 1992, in the
14th Judicial  District Court of Dallas  County.  The petition  sought  recovery
against the  Partnership's  former  auditors,  Ernst & Young, for negligence and
fraud in  failing  to detect  and/or  report  overcharges  of  fees/expenses  by
Southmark,   the  former  general   partner.   The  former   auditors   asserted
counterclaims  against the Affiliated  Partnerships  based on alleged fraudulent
misrepresentations  made  to  the  auditors  by  the  former  management  of the
Affiliated Partnerships (Southmark) in the form of client representation letters
executed  and   delivered  to  the   auditors  by  Southmark   management.   The
counterclaims sought recovery of attorneys' fees and costs incurred in defending
this action. The original petition also alleged causes of action against certain
former officers and directors of the Partnership's  original general partner for
breach  of  fiduciary  duty,  fraud  and  conspiracy  relating  to the  improper
assessment and payment of certain administrative  fees/expenses.  On January 11,
1994 the allegations against the former officers and directors were dismissed.

The  trial  court  granted  summary  judgment  in favor of Ernst & Young and BDO
Seidman on the fraud and negligence  claims based on the statute of limitations.
The Affiliated Partnerships appealed the summary judgment to the Dallas Court of
Appeals.  In August 1995, the appeals court upheld all of the summary  judgments
in favor of the defendants,  except it overturned the summary judgment as to the
fraud claim against Ernst & Young.  Therefore,  the  plaintiffs  will proceed to
trial unless a reasonable  settlement can be effected  between the parties.  The
ultimate outcome of this litigation cannot be determined at this time.

2) High River Limited  Partnership vs. McNeil Partners,  L.P., McNeil Investors,
Inc.,  McNeil Pacific  Investors 1972,  McNeil Real Estate Fund V, Ltd.,  McNeil
Real Estate Fund IX, Ltd.,  McNeil Real Estate Fund X, Ltd.,  McNeil Real Estate
Fund XI, Ltd.,  McNeil Real Estate Fund XIV,  Ltd.,  McNeil Real Estate Fund XV,
Ltd.,  McNeil  Real Estate Fund XX,  L.P.,  McNeil Real Estate Fund XXIV,  L.P.,
McNeil  Real  Estate  Fund XXV,  L.P.,  Robert A.  McNeil and  Carole J.  McNeil
(L95012). High River Limited Partnership ("High River") filed this action in the
United  States  District  Court for the  Southern  District of New York  against
McNeil  Partners,  L.P.,  McNeil  Investors,   Inc.  and  Mr.  and  Mrs.  McNeil
requesting,  among other things,  names and addresses of the limited partners of
the ten  partnerships  listed above (the  "Funds").  The district court issued a
preliminary  injunction  against the Funds  requiring  them to commence  mailing
materials relating to High River tender offer materials on August 14, 1995.

On August 18, 1995, McNeil Partners,  L.P.,  McNeil Investors,  Inc., the Funds,
and Mr. and Mrs.  McNeil  filed an Answer  and  Counterclaim.  The  counterclaim
principally  asserted that (1) the High River tender  offers were  undertaken in
violation of the federal securities laws, on the basis of material,  non-public,
and  confidential  information,  and (2)  that the High  River  offer  documents
omitted and/or misrepresented  certain material information about the High River
tender offers.  The counterclaim  sought a preliminary and permanent  injunction
against the  continuation  of the High River tender  offers and,  alternatively,
ordering  corrective  disclosure  with respect to allegedly false and misleading
statements contained in the tender offer documents.

The High River tender offer expired on October 6, 1995. The  defendants  believe
that the action is moot and expect the matter to be dismissed shortly.

3) Martha Hess, et. al. v. Southmark Equity Partners II, Ltd,,  Southmark Income
Investors, Ltd. (presently known as McNeil Real Estate Fund XX, L.P.), Southmark
Equity Partners, Ltd., Southmark Realty Partners III, Ltd., and Southmark Realty
Partners II, Ltd., et al. ("Hess");  Kotowski v. Southmark Equity Partners, Ltd.
and  Donald  Arceri  v.  Southmark  Income  Investors,  Ltd.  These  cases  were
previously  pending  in the  Illinois  Appellate  Court for the  First  District
("Appellate  Court"),  as consolidated case no. 90-107.  Consolidated with these
cases are an additional 14 matters against unrelated partnership  entities.  The
Hess case was filed on May 20, 1988, by Martha Hess,  individually and on behalf
of a putative class of those similarly situated. The original, first, second and
third  amended  complaints in Hess sought  rescission,  pursuant to the Illinois
Securities  Act, of over $2.7  million of principal  invested in five  Southmark
(now  McNeil)  partnerships,  and other relief  including  damages for breach of
fiduciary  duty and  violation  of the  Illinois  Consumer  Fraud and  Deceptive
Business Practices Act. The original, first, second and third amended complaints
in Hess were dismissed against the  defendant-group  because the Appellate Court
held that they were not the proper  subject of a class  action  complaint.  Hess
was,  thereafter,  amended  a fourth  time to state  causes  of  action  against
unrelated  partnership  entities.  Hess went to judgment  against that unrelated
entity and the judgment, along with the prior dismissal of the class action, was
appealed.  The Hess appeal was decided by the Appellate  Court during 1992.  The
Appellate  Court  affirmed the  dismissal  of the breach of  fiduciary  duty and
consumer  fraud  claims.  The  Appellate  Court did,  however,  reverse in part,
holding that certain  putative class members could file class action  complaints
against the  defendant-group.  Although leave to appeal to the Illinois  Supreme
Court was sought,  the Illinois  Supreme Court  refused to hear the appeal.  The
effect of the denial is that the Appellate Court's opinion remains standing.  On
June 15, 1994, the Appellate  Court issued its mandate  sending the case back to
trial court.

In late  January  1995,  the  plaintiffs  filed  a  Motion  to  File an  Amended
Consolidated  Class Action Complaint,  which amends the complaint to name McNeil
Partners,  L.P. as the successor general partner to Southmark  Investment Group.
In February 1995, the plaintiffs filed a Motion for Class Certification.

In September 1995, the court granted the  plaintiffs'  Motion to File an Amended
Complaint,  to Consolidate  and for Class  Certification.  The  defendants  have
answered the  complaint and have plead that the  plaintiffs  did not give timely
notice of their right to rescind  within six months of knowing  that right.  The
ultimate outcome of this litigation cannot be determined at this time.

4) Robert Lewis vs. McNeil Partners,  L.P.,  McNeil  Investors,  Inc., Robert A.
McNeil, et al - In the District Court of Dallas County,  Texas,  A-14th Judicial
District,  Cause No. 95-08535 (Class Action). The plaintiff,  Robert Lewis, is a
limited partner with McNeil Pacific Investors Fund 1972, McNeil Real Estate Fund
X, Ltd. and McNeil Real Estate Fund XV, Ltd. The plaintiff brings this action on
his own  behalf  and as a class  action on  behalf  of the class of all  limited
partners of McNeil Pacific Investors Fund 1972, McNeil Real Estate Fund V, Ltd.,
McNeil Real Estate Fund IX, Ltd.,  McNeil Real Estate Fund X, Ltd.,  McNeil Real
Estate Fund XI, Ltd., McNeil Real Estate Fund XIV, Ltd., McNeil Real Estate Fund
XV, Ltd.,  McNeil Real Estate Fund XX, L.P.,  McNeil Real Estate Fund XXIV, L.P.
and McNeil Real Estate Fund XXV, L.P as of August 4, 1995.

The plaintiff alleges that McNeil Partners, L.P., McNeil Investors, Inc., Robert
A. McNeil, and other senior officers  (collectively,  the "Defendants") breached
their fiduciary  duties by, amoung other things,  (1) failing to attempt to sell
the properties owned by the Funds (the  "Properties") and extending the lives of
the Funds  indefinitely,  contrary  to the  Funds'  business  plans,  (2) paying
distributions  to  themselves  and  generating  fees for their  affiliates,  (3)
refusing to make  significant  distributions  to the class members,  despite the
fact that the Funds have positive cash flows and substantial cash balances,  and
(4) failing to take steps to create an auction market for Fund equity interests,
despite the fact that a third party bidder filed tender offers for approximately
forty-five  percent  (45%) of the  outstanding  units of each of the Funds.  The
plaintiff  also  claims  that  the  Defendants  have  breached  the  partnership
agreements  by failing to take steps to liquidate  the  Properties  and by their
alteration of the Funds' primary purposes,  their acts in contravention of these
agreements,  and their use of the Fund assets for their own  benefit  instead of
for the benefit of the Funds.

The Defendants deny that there is any merit to the  plaintiff's  allegations and
intend to vigorously defend this action.

5) James F.  Schofield,  Gerald C.  Gillett  and  Donna S.  Gillett  vs.  McNeil
Partners,  L.P., McNeil Investors,  Inc., McNeil Real Estate  Management,  Inc.,
Robert A.  McNeil,  Carole J.  McNeil,  et al,  McNeil Real Estate Fund V, Ltd.,
McNeil Real Estate Fund IX, Ltd.,  McNeil Real Estate Fund X, Ltd.,  McNeil Real
Estate Fund XI, Ltd., McNeil Real Estate Fund XIV, Ltd., McNeil Real Estate Fund
XV, Ltd.,  McNeil Real Estate Fund XX, L.P., McNeil Real Estate Fund XXIV, L.P.,
McNeil Real Estate Fund XXV,  L.P. - Superior  Court of the State of  California
for the County of Los Angeles,  Case No. BC133799  (Class and Derivative  Action
Complaint),  United States District Court,  Southern  District of New York, Case
No.   95CIV.6711   (Class   and   Derivative   Action   Complaint).   These  are
corporate/securities  class and derivative  actions brought in state and federal
court by limited  partners  of each of the nine  limited  partnerships  that are
named as Nominal Defendants as listed above (the "Nine Funds").

The plaintiffs  allege that  defendants  McNeil  Investors,  Inc., its affiliate
McNeil Real Estate  Management,  Inc. and four of their senior  officers  and/or
directors have breached their  fiduciary  duties.  Specifically,  the plaintiffs
allege  that the  defendants  have  caused the Nine Funds to enter into  several
wasteful transactions that have no business purpose or benefit to the Nine Funds
and which have rendered such units highly  illiquid and  artificially  depressed
the prices  that are  available  for units on the  limited  resale  market.  The
plaintiffs  also allege that the defendants  have engaged in a course of conduct
to  prevent  the  acquisition  of units by Carl  Icahn by  disseminating  false,
misleading and inadequate  information.  The plaintiffs  further allege that the
defendants have acted to advance their own personal  interests at the expense of
the Nine Funds'  public unit holders by failing to sell  partnership  properties
and failing to make distributions to unitholders and, thereby, have breached the
partnership agreements.

The defendants deny that there is any merit to the  plaintiffs'  allegations and
intend to vigorously defend these actions.

6) Alfred Napoletano vs. McNeil Partners,  L.P., McNeil Investors,  Inc., Robert
A. McNeil,  Carole J. McNeil,  McNeil Pacific  Investors Fund 1972,  McNeil Real
Estate Fund V, Ltd.,  McNeil Real Estate Fund IX, Ltd.,  McNeil Real Estate Fund

Estate Fund XXIV,  L.P.,  McNeil Real Estate Fund XXV, L.P. - Superior  Court of
the State of California,  County of Los Angeles, Case No. BC133849 (class action
complaint).

The  plaintiff  brings this class action on behalf of a class of all persons and
entities who are current  owners of units and/or are limited  partners in one or
more of the partnerships  referenced above (the "Funds").  The plaintiff alleges
that the defendants  have breached their  fiduciary  duties to the class members
by, among other things, (1) taking steps to prevent the consummation of the High
River  tender  offers,  (2)  failing to take steps to maximize  unitholders'  or
limited partners' values, including failure to liquidate the properties owned by
the Funds,  (3) managing the Funds so as to extend  indefinitely the present fee
arrangements,  and (4) paying  itself and entities  owned and  controlled by the
general partner excessive fees and  reimbursements of general and administrative
expenses.

The defendants deny that there is any merit to the  plaintiff's  allegations and
intend to vigorously defend this action.

7) Warren Heller vs. McNeil Partners,  L.P., McNeil  Investors,  Inc., Robert A.
McNeil, Carole J. McNeil, McNeil Pacific Investors Fund 1972, McNeil Real Estate
Fund V, Ltd., McNeil Real Estate Fund IX, Ltd., McNeil Real Estate Fund X, Ltd.,

XXIV,  L.P.,  McNeil Real Estate Fund XXV, L.P. - Superior Court of the State of
California, County of Los Angeles, Case No. BC133957 (class action complaint).

The  plaintiff  brings this class action on behalf of a class of all persons and
entities who are current  owners of units and/or are limited  partners in one or
more of the Funds referenced  above.  The plaintiff  alleges that the defendants
have  breached  their  fiduciary  duties to the class  members  by,  among other
things,  (1) taking steps to prevent the  consummation  of the High River tender
offers, (2) failing to take steps to maximize  unitholders' or limited partners'
values,  including  failure to liquidate the properties  owned by the Funds, (3)
managing the Funds so as to extend  indefinitely  the present fee  arrangements,
and (4) paying itself and entities owned and  controlled by the general  partner
excessive fees and reimbursements of general and administrative expenses.

The defendants deny that there is any merit to the  plaintiff's  allegations and
intend to vigorously defend this action.

8) High River Limited  Partnership v. McNeil  Partners L.P.,  McNeil  Investors,
Inc.,  McNeil Pacific  Investors 1972,  McNeil Real Estate Fund V, Ltd.,  McNeil
Real Estate Fund IX, Ltd.,  McNeil Real Estate Fund X, Ltd.,  McNeil Real Estate
Fund XI, Ltd.,  McNeil Real Estate Fund XIV,  Ltd.,  McNeil Real Estate Fund XV,
Ltd.,  McNeil  Real Estate Fund XX,  L.P.,  McNeil Real Estate Fund XXIV,  L.P.,
McNeil  Real  Estate  Fund XXV,  L.P.,  Robert A.  McNeil and Carole J. McNeil -
United States District Court for the Southern District of New York, (Case No. 95
Civ. 9488) (Second Action).

On November 7, 1995,  High River  commenced a second  complaint  which  alleges,
inter alia, that McNeil's Schedule 14D-9 filed in connection with the High River
tender  offers was  materially  false and  misleading,  in violation of Sections
14(d) and 14(e) of the Securities Exchange Act of 1934, 15 U.S.C. Section 78n(d)
and (e), and the SEC  Regulations  promulgated  thereunder;  and that High River
further  alleges  that  McNeil has  wrongfully  refused to admit High River as a
limited partner to the Funds. Additionally, High River purports to assert claims
derivatively on behalf of Funds IX, XI, XV, XXIV and XXV, for breach of contract
and breach of  fiduciary  duty,  asserting  that McNeil has charged  these Funds
excessive fees. High River's complaint seeks, inter alia, preliminary injunctive
relief  requiring McNeil to admit High River as a limited partner in each of the
ten Funds and to transfer  the  tendered  units of interest in the Funds to High
River;  an unspecified  award of damages payable to High River and an additional
unspecified  award of damages  payable  to  certain of the Funds;  an order that
defendants must discharge  their fiduciary  duties and must account for all fees
they have received from certain of the Funds; and attorneys' fees.

The defendants deny that there is any merit to the  plaintiff's  allegations and
intend to vigorously defend this action.

ITEM 5.  OTHER INFORMATION
- ------   -----------------

As previously  disclosed,  on an  unsolicited  basis,  High River, a partnership
controlled by Carl Icahn,  announced  that it had commenced an offer to purchase
22,280 units of limited partnership  interest in the Partnership  (approximately
45% of the  Partnership's  units) at  $100.00  per unit.  The  tender  offer was
originally  due to expire on August  31,  1995.  In  connection  therewith,  the
parties entered into certain negotiations and discussions regarding, among other
things,  possible transactions between the parties and their affiliates,  McNeil
Partners,  L.P., McNeil Investors,  Inc., and McREMI. On September 19, 1995, the
parties  having  not  reached  any  resolution  on the  terms  of  the  proposed
transactions,  McNeil Partners,  L.P. terminated the parties'  discussion.  High
River had extended its offer  several times until the final  expiration  date of
October  6,  1995.  On  October  11,  1995 High  River  announced  that based on
preliminary  information  furnished  by the  depositary  for the  tender  offer,
approximately  5,883 limited  partnership units of the Partnership were tendered
and not withdrawn  prior to the  expiration of the tender offer.  On October 12,
1995,  McNeil  Partners,  L.P.  announced  that it  would  continue  to  explore
potential  avenues  to enhance  the value of the  Partnership  units,  which may
include, among other things, asset sales, refinancings of Partnership properties
followed by  distributions  or tender  offers for units of limited  partnership.
There can be no  assurance  that any such  plans  will  develop or that any such
transactions will be consummated.
