                          NOTES TO FINANCIAL STATEMENTS
                                   (Unaudited)


Note A - Basis of Presentation

The accompanying unaudited financial statements of National Property Investors 4
(the  "Partnership" or the  "Registrant")  have been prepared in accordance with
generally accepted accounting  principles for interim financial  information and
with  the  instructions  to Form  10-QSB  and Item  310(b)  of  Regulation  S-B.
Accordingly,  they do not include all of the information and footnotes  required
by generally accepted accounting  principles for complete financial  statements.
In the opinion of NPI Equity Investments, Inc. (the "Managing General Partner"),
all adjustments  (consisting of normal recurring accruals)  considered necessary
for a fair  presentation  have been  included.  Operating  results for the three
month period ended March 31, 2003, are not necessarily indicative of the results
that may be expected for the fiscal year ending  December 31, 2003.  For further
information, refer to the financial statements and footnotes thereto included in
the  Partnership's  Annual  Report on Form  10-KSB  for the  fiscal  year  ended
December 31, 2002.  The Managing  General  Partner is a subsidiary  of Apartment
Investment  and  Management  Company  ("AIMCO"),  a publicly  traded real estate
investment trust.

Note B - Transactions with Affiliated Parties

The  Partnership  has no employees  and is  dependent  on the  Managing  General
Partner  and  its  affiliates  for  the  management  and  administration  of all
partnership  activities.  The  Partnership  Agreement  provides  for payments to
affiliates for services and for  reimbursement of certain  expenses  incurred by
affiliates on behalf of the Partnership.

Affiliates of the Managing  General  Partner are entitled to receive 5% of gross
receipts  from the  Partnership's  property for  providing  property  management
services.  The  Partnership  paid to such affiliates  approximately  $90,000 and
$95,000 for the three month periods ended March 31, 2003 and 2002, respectively,
which is included in operating expenses.

Affiliates  of  the  Managing   General  Partner  received   reimbursements   of
accountable  administrative  expenses  amounting  to  approximately  $43,000 and
$65,000 for the three month periods ended March 31, 2003 and 2002, respectively,
which  are  included  in  general  and  administrative  expense  and  investment
properties.   Included  in  these  amounts  are  fees  related  to  construction
management  services provided by an affiliate of the Managing General Partner of
approximately  $6,000 for the three months  ended March 31, 2002.  There were no
such fees for the three months ended March 31, 2003. The construction management
service fees are  calculated  based on a percentage of current  additions to the
Partnership's investment property.

For services relating to the  administration of the Partnership and operation of
the Partnership's  property, the Managing General Partner is entitled to receive
payment for non-accountable  expenses up to a maximum of $100,000 per year based
upon the number of Partnership units sold, subject to certain  limitations.  The
Managing  General  Partner  received  payment  for  non-accountable  expenses of
approximately  $21,000  during the three months  ended March 31, 2003,  which is
included in general  and  administrative  expense.  No such  payments  were made
during the three months ended March 31, 2002.

In  addition  to the amounts  discussed  above,  as  compensation  for  services
rendered in managing the  Partnership,  the Managing General Partner is entitled
to receive Partnership management fees in conjunction with distributions of cash
from operations,  subject to certain limitations.  During the three month period
ended March 31,  2003,  approximately  $7,000 was paid in  conjunction  with the
distributions  from  operations  and is included  in general and  administrative
expense. No such fee was paid during the three months ended March 31, 2002.

The Managing  General  Partner has made available to the  Partnership a $300,000
line of credit. At the present time, the Partnership has no outstanding  amounts
due under this line of credit.

The  Partnership  insures its  property up to certain  limits  through  coverage
provided by AIMCO which is  generally  self-insured  for a portion of losses and
liabilities  related to workers  compensation,  property  casualty  and  vehicle
liability.  The Partnership  insures its property above the AIMCO limits through
insurance  policies  obtained  by  AIMCO  from  insurers  unaffiliated  with the
Managing  General  Partner.  During 2003 and 2002,  the  Partnership's  cost for
insurance  coverage  and fees  associated  with  policy  claims  administrations
provided by AIMCO and its affiliates will be approximately  $78,000 and $94,000,
respectively.

Note C - Legal Proceedings

In March 1998, several putative unit holders of limited partnership units of the
Partnership  commenced an action  entitled  Rosalie  Nuanes,  et al. v. Insignia
Financial Group, Inc., et al. (the "Nuanes action") in the Superior Court of the
State of  California  for the  County  of San  Mateo.  The  plaintiffs  named as
defendants,  among others,  the  Partnership,  its Managing  General Partner and
several of their  affiliated  partnerships  and corporate  entities.  The action
purports  to  assert  claims  on  behalf  of a class  of  limited  partners  and
derivatively  on behalf  of a number  of  limited  partnerships  (including  the
Partnership)  which are named as nominal  defendants,  challenging,  among other
things,  the  acquisition  of  interests  in certain  Managing  General  Partner
entities by Insignia Financial Group, Inc. ("Insignia") and entities which were,
at one  time,  affiliates  of  Insignia;  past  tender  offers  by the  Insignia
affiliates to acquire limited partnership units;  management of the partnerships
by the  Insignia  affiliates;  and the series of  transactions  which  closed on
October 1, 1998 and February 26, 1999 whereby  Insignia and Insignia  Properties
Trust,  respectively,  were merged  into AIMCO.  The  plaintiffs  seek  monetary
damages and equitable relief, including judicial dissolution of the Partnership.
On June 25, 1998, the Managing General Partner filed a motion seeking  dismissal
of the action.  In lieu of responding  to the motion,  the  plaintiffs  filed an
amended  complaint.  The Managing General Partner filed demurrers to the amended
complaint which were heard February 1999.

Pending the ruling on such  demurrers,  settlement  negotiations  commenced.  On
November 2, 1999,  the parties  executed and filed a Stipulation  of Settlement,
settling claims, subject to court approval, on behalf of the Partnership and all
limited partners who owned units as of November 3, 1999. Preliminary approval of
the  settlement  was obtained on November 3, 1999 from the Court,  at which time
the Court set a final  approval  hearing for  December  10,  1999.  Prior to the
December  10,  1999  hearing,  the  Court  received  various  objections  to the
settlement, including a challenge to the Court's preliminary approval based upon
the alleged lack of authority of prior lead counsel to enter the settlement.  On
December 14, 1999, the Managing  General  Partner and its affiliates  terminated
the  proposed  settlement.  In  February  2000,  counsel  for some of the  named
plaintiffs filed a motion to disqualify plaintiff's lead and liaison counsel who
negotiated  the  settlement.  On June  27,  2000,  the  Court  entered  an order
disqualifying  them  from the case and an  appeal  was  taken  from the order on
October 5, 2000. On December 4, 2000, the Court  appointed the law firm of Lieff
Cabraser  Heimann & Bernstein  LLP as new lead  counsel for  plaintiffs  and the
putative class.  Plaintiffs filed a third amended complaint on January 19, 2001.
On March 2, 2001,  the  Managing  General  Partner  and its  affiliates  filed a
demurrer to the third amended  complaint.  On May 14, 2001,  the Court heard the
demurrer to the third amended  complaint.  On July 10, 2001, the Court issued an
order  sustaining  defendants'  demurrer on certain  grounds.  On July 20, 2001,
Plaintiffs filed a motion for reconsideration of the Court's July 10, 2001 order
granting in part and denying in part defendants' demurrer. On September 7, 2001,
Plaintiffs  filed a fourth amended class and  derivative  action  complaint.  On
September 12, 2001, the Court denied Plaintiffs' motion for reconsideration.  On
October 5, 2001, the Managing General Partner and affiliated  defendants filed a
demurrer to the fourth amended complaint,  which was heard on December 11, 2001.
On February 2, 2002,  the Court served its order  granting in part the demurrer.
The  Court has  dismissed  without  leave to amend  certain  of the  plaintiffs'
claims.  On February 11, 2002,  plaintiffs  filed a motion  seeking to certify a
putative  class  comprised of all  non-affiliated  persons who own or have owned
units  in  the  partnerships.   The  Managing  General  Partner  and  affiliated
defendants  oppose the motion.  On April 29,  2002,  the Court held a hearing on
plaintiffs' motion for class  certification and took the matter under submission
after further  briefing,  as ordered by the court, was submitted by the parties.
On July 10, 2002,  the Court entered an order vacating the trial date of January
13, 2003 (as well as the pre-trial and discovery  cut-off  dates) and stayed the
case in its entirety  through November 7, 2002 so that the parties could have an
opportunity  to discuss  settlement.  On October 30, 2002,  the court entered an
order extending the stay in effect through January 10, 2003.

On January 8, 2003,  the parties filed a  Stipulation  of Settlement in proposed
settlement of the Nuanes action and the Heller action  described below. On April
4, 2003, the Court preliminarily approved the settlement and scheduled a hearing
on final approval for June 2, 2003.

In general  terms,  the  proposed  settlement  provides  for  certification  for
settlement  purposes of a settlement class consisting of all limited partners in
this  Partnership and others (the  "Partnerships")  as of December 20, 2002, the
dismissal  with  prejudice  and  release  of claims  in the  Nuanes  and  Heller
litigation,  payment by AIMCO of $9.9  million  (which shall be  distributed  to
settlement  class  members  after  deduction of attorney fees and costs of class
counsel and certain costs of settlement) and up to $1 million toward the cost of
independent  appraisals of the  Partnerships'  properties  by a Court  appointed
appraiser.  An affiliate of the Managing General Partner has also agreed to make
a tender offer to purchase all of the partnership  interests in the Partnerships
within one year of final  approval,  if it is granted,  and to provide  partners
with the  independent  appraisals  at the time of these  tenders.  The  proposed
settlement  also provides for the  limitation  of the allowable  costs which the
Managing  General  Partner or its  affiliates  will charge the  Partnerships  in
connection with this litigation and imposes limits on the class counsel fees and
costs in this litigation.  On April 11, 2003,  notice was distributed to limited
partners providing the details of the proposed settlement.

During the third  quarter of 2001, a complaint  (the "Heller  action") was filed
against  the same  defendants  that are named in the  Nuanes  action,  captioned
Heller v. Insignia Financial Group. On or about August 6, 2001, plaintiffs filed
a first amended  complaint.  The first amended complaint in the Heller action is
brought as a purported  derivative  action,  and asserts  claims for among other
things  breach  of  fiduciary  duty;  unfair  competition;   conversion,  unjust
enrichment;  and judicial  dissolution.  Plaintiffs in the Nuanes action filed a
motion to  consolidate  the Heller action with the Nuanes action and stated that
the Heller action was filed in order to preserve the derivative claims that were
dismissed  without  leave to amend in the Nuanes action by the Court order dated
July 10, 2001. On October 5, 2001, the Managing  General  Partner and affiliated
defendants  moved to strike the first  amended  complaint  in its  entirety  for
violating  the Court's July 10, 2001 order  granting in part and denying in part
defendants'  demurrer in the Nuanes action, or alternatively,  to strike certain
portions of the complaint based on the statute of limitations.  Other defendants
in the action  demurred to the fourth  amended  complaint,  and,  alternatively,
moved to strike the complaint. On December 11, 2001, the court heard argument on
the motions  and took the matters  under  submission.  On February 4, 2002,  the
Court  served  notice of its order  granting  defendants'  motion to strike  the
Heller complaint as a violation of its July 10, 2001 order in the Nuanes action.
On March 27, 2002,  the plaintiffs  filed a notice  appealing the order striking
the  complaint.  Before  completing  briefing on the appeal,  the parties stayed
further proceedings in the appeal pending the Court's review of the terms of the
proposed settlement described above.

Estate of Harry  Schubert v.  National  Property  Investors  4, Civil Action No.
97-09129, Court of Common Pleas of Bucks County, Pennsylvania.  During 1998, the
Plaintiff brought action against the Partnership  alleging that as the result of
carbon monoxide and methane  poisoning due to a malfunctioning  heat unit in the
apartment at the Partnership's property, which was leased by decedent's son, the
decedent lost consciousness for several hours,  suffered respiratory arrest, and
suffered  other pains and injuries.  The Plaintiff  alleges  breach of contract,
fraud,  violations of the Unfair Trade Practices and Consumer Protection Law and
negligence  resulting  in wrongful  death.  This matter is in the  discovery  of
litigation. The Partnership is vigorously defending this matter.

The  Managing  General  Partner  does  not  anticipate  that  any  costs  to the
Partnership, whether legal or settlement costs, associated with these cases will
be material to the Partnership's overall operations.

The  Partnership is unaware of any other pending or outstanding  litigation that
is not of a routine nature arising in the ordinary course of business.

ITEM 2.     MANAGEMENT'S DISCUSSION AND ANALYSIS OR PLAN OF OPERATION

The matters discussed in this report contain certain forward-looking statements,
including, without limitation, statements regarding future financial performance
and the effect of government  regulations.  The discussions of the  Registrant's
business  and  results  of  operations,   including  forward-looking  statements
pertaining to such matters,  do not take into account the effects of any changes
to the  Registrant's  business  and results of  operations.  Actual  results may
differ  materially  from those described in the  forward-looking  statements and
will  be  affected  by  a  variety  of  risks  and  factors  including,  without
limitation:  national and local economic  conditions;  the terms of governmental
regulations that affect the Registrant and interpretations of those regulations;
the competitive  environment in which the Registrant operates;  financing risks,
including the risk that cash flows from  operations may be  insufficient to meet
required  payments of  principal  and  interest;  real estate  risks,  including
variations  of real  estate  values and the  general  economic  climate in local
markets and competition for tenants in such markets; and possible  environmental
liabilities.   Readers  should  carefully  review  the  Registrant's   financial
statements and the notes thereto,  as well as the risk factors  described in the
documents  the  Registrant  files  from  time to time  with the  Securities  and
Exchange Commission.

The Partnership's investment property consists of one apartment complex, Village
of Pennbrook Apartments,  located in Falls Township,  Pennsylvania.  The average
occupancy  was 92% and 96% for the three month  periods ended March 31, 2003 and
2002,  respectively.  The decrease in average  occupancy  was due primarily to a
weak economy and layoffs at several companies in the property's market area.

Results of Operations

The Partnership  realized net income of  approximately  $97,000 and $296,000 for
the three  months ended March 31, 2003 and 2002,  respectively.  The decrease in
net income is  attributable  to a decrease in total  revenues and an increase in
total  expenses.  Total  revenues  decreased  due to a decrease in rental income
caused by a  decrease  in  average  occupancy  at the  Partnership's  investment
property,  as discussed above. This decrease was partially offset by an increase
in other income caused by increased late charges and lease  cancellation fees at
the property.

The increase in total expenses was due to increases in operating and general and
administrative  expenses  partially  offset by a decrease in  interest  expense.
Depreciation  expense and property tax expense remained  relatively constant for
the comparable periods.  The increase in operating expenses was primarily due to
an increase in natural gas  expense  due to an  unusually  severe  winter and an
increase in maintenance expenses due to increases in interior painting, yard and
ground  expenses  and snow removal due to a late winter  storm.  The increase in
general and administrative fees is due to an increase in Partnership  management
fees and non-accountable  reimbursements associated with distributions partially
offset by a decrease in accountable  reimbursements  paid to an affiliate of the
Managing General Partner. The decrease in interest expense is due to the payment
of scheduled principal payments on the mortgage encumbering the property.

Included  in general  and  administrative  expenses  are  reimbursements  to the
Managing General Partner allowed under the Partnership Agreement associated with
its  management  of the  Partnership.  Costs  associated  with the quarterly and
annual  communications  with investors and regulatory  agencies,  and the annual
audit required by the Partnership Agreement are also included.

As part of the ongoing  business plan of the  Partnership,  the Managing General
Partner  monitors the rental market  environment of its  investment  property to
assess the feasibility of increasing rents,  maintaining or increasing occupancy
levels and protecting  the  Partnership  from increases in expenses.  As part of
this plan, the Managing General Partner attempts to protect the Partnership from
the burden of  inflation-related  increases in expenses by increasing  rents and
maintaining a high overall  occupancy  level.  However,  due to changing  market
conditions,  which  can  result  in the use of  rental  concessions  and  rental
reductions to offset softening market conditions, there is no guarantee that the
Managing General Partner will be able to sustain such a plan.

Capital Resources and Liquidity

At  March  31,  2003,  the  Partnership   had  cash  and  cash   equivalents  of
approximately  $448,000 as compared to approximately $430,000 at March 31, 2002.
Cash and cash  equivalents  increased  approximately  $166,000 from December 31,
2002.  This  increase  was due to  approximately  $732,000  of cash  provided by
operating activities partially offset by approximately  $445,000 and $121,000 of
cash used in financing  and  investing  activities,  respectively.  Cash used in
financing  activities  consisted  of  distributions  paid  to the  partners  and
payments made on the mortgage encumbering Village of Pennbrook Apartments.  Cash
used  in   investing   activities   consisted  of  property   improvements   and
replacements.  The Partnership  invests its working capital reserves in interest
bearing accounts.

The Managing  General Partner has extended to the Partnership a $300,000 line of
credit.  At the present time, the  Partnership  has no  outstanding  amounts due
under this line of credit.  Based on present plans, the Managing General Partner
does not anticipate  the need to borrow in the near future.  Other than cash and
cash equivalents,  the line of credit is the Partnership's only unused source of
liquidity.

The sufficiency of existing  liquid assets to meet future  liquidity and capital
expenditure   requirements   is  directly   related  to  the  level  of  capital
expenditures required at the property to adequately maintain the physical assets
and other operating  needs of the Partnership and to comply with Federal,  state
and local  legal and  regulatory  requirements.  The  Managing  General  Partner
monitors  developments  in the area of legal and  regulatory  compliance  and is
studying  new  federal  laws,  including  the  Sarbanes-Oxley  Act of 2002.  The
Sarbanes-Oxley Act of 2002 mandates or suggests  additional  compliance measures
with regard to governance,  disclosure, audit and other areas. In light of these
changes,  the Partnership  expects that it will incur higher expenses related to
compliance,  including  increased  legal and audit  fees.  Capital  improvements
planned for the Partnership's investment property are detailed below.

During  the  three  months  ended  March 31,  2003,  the  Partnership  completed
approximately   $180,000  of  capital   improvements  at  Village  at  Pennbrook
Apartments,  consisting primarily of a gas submetering  project,  floor covering
and water heater  replacements,  heating and structural upgrades and parking lot
improvements.  These  improvements  were funded from  operating  cash flow.  The
Partnership  evaluates the capital  improvement needs of the property during the
year and  currently  expects  to  complete  an  additional  $244,000  in capital
improvements  during the remainder of 2003. The additional capital  improvements
will  consist   primarily  of  floor   covering,   appliance  and  water  heater
replacements,  balcony  improvements and air conditioning  upgrades.  Additional
capital improvements may be considered and will depend on the physical condition
of the property as well as the anticipated cash flow generated by the property.

The  capital  improvements  will be  incurred  only if  cash is  available  from
operations  or from  Partnership  reserves.  To the  extent  that such  budgeted
capital improvements are completed,  the Partnership's  distributable cash flow,
if any, may be adversely affected at least in the short term.

The  Partnership's  assets are thought to be sufficient for any near-term  needs
(exclusive  of  capital   improvements)   of  the   Partnership.   The  mortgage
indebtedness of  approximately  $29,297,000 is being amortized over 20 years and
will mature in  September  2021 at which time the  mortgage is  scheduled  to be
fully amortized.

Pursuant to the Partnership Agreement,  the term of the Partnership is scheduled
to expire on December 31, 2005. Accordingly,  prior to such date the Partnership
will need to  either  sell its  investment  property  or extend  the term of the
Partnership.

The Partnership  distributed the following amounts during the three months ended
March 31, 2003 and 2002 (in thousands, except per unit data):

</TABLE>

The  Partnership's  cash  available  for  distribution  is reviewed on a monthly
basis. Future cash distributions will depend on the levels of net cash generated
from operations,  the availability of cash reserves,  and the timing of the debt
maturity,  refinancing, and/or property sale. There can be no assurance that the
Partnership  will  generate  sufficient  funds from  operations  after  required
capital improvements to permit further  distributions to its partners during the
remainder of 2003 or subsequent periods.

Other

In addition to its  indirect  ownership of the general  partner  interest in the
Partnership,  AIMCO and its affiliates  owned 45,310 limited  partnership  units
(the "Units") in the Partnership representing 75.51% of the outstanding Units at
March 31, 2003. A number of these Units were acquired  pursuant to tender offers
made by AIMCO or its  affiliates.  It is possible  that AIMCO or its  affiliates
will acquire additional units of limited partnership interest in the Partnership
in  exchange  for  cash or a  combination  of cash and  units  in the  operating
partnership of AIMCO either through  private  purchases or tender offers.  Under
the  Partnership  Agreement,  unitholders  holding a  majority  of the Units are
entitled to take action with respect to a variety of matters which would include
voting on certain  amendments to the Partnership  Agreement and voting to remove
the  Managing  General  Partner.  As a result of its  ownership of 75.51% of the
outstanding Units, AIMCO is in a position to influence all such voting decisions
with  respect  to  the  Registrant.  With  respect  to  26,466  units,  Insignia
Properties,  LP, an  affiliate  of AIMCO,  is required  to vote such Units:  (i)
against any increase in compensation  payable to the Managing General Partner or
to affiliates;  and (ii) on all other matters submitted by it or its affiliates,
in proportion  to the votes cast by  non-tendering  unitholders.  Except for the
foregoing,  no other limitations are imposed on AIMCO's or Insignia  Properties,
L.P.'s ability to influence  voting  decisions with respect to the  Partnership.
Although  the Managing  General  Partner  owes  fiduciary  duties to the limited
partners of the  Partnership,  the Managing  General Partner also owes fiduciary
duties to AIMCO as its sole stockholder. As a result, the duties of the Managing
General Partner, as managing general partner, to the Partnership and its limited
partners may come into conflict with the duties of the Managing  General Partner
to AIMCO, as its sole stockholder.

Critical Accounting Policies and Estimates

The consolidated financial statements are prepared in accordance with accounting
principles generally accepted in the United States which require the Partnership
to  make  estimates  and  assumptions.  The  Partnership  believes  that  of its
significant  accounting  policies,  the following may involve a higher degree of
judgment and complexity.

Impairment of Long-Lived Assets

The  Partnership's  investment  property is recorded at cost,  less  accumulated
depreciation,  unless considered impaired.  If events or circumstances  indicate
that the carrying amount of the property may be impaired,  the Partnership  will
make an assessment of its  recoverability by estimating the undiscounted  future
cash flows,  excluding interest charges, of the property. If the carrying amount
exceeds the aggregate  future cash flows,  the  Partnership  would  recognize an
impairment  loss to the extent the carrying amount exceeds the fair value of the
property.

Real  property  investments  are  subject  to varying  degrees of risk.  Several
factors  may  adversely  affect  the  economic  performance  and  value  of  the
Partnership's   investment  property.  These  factors  include  changes  in  the
national,  regional and local economic  climate;  local  conditions,  such as an
oversupply  of  multifamily   properties;   competition   from  other  available
multifamily  property  owners and changes in market  rental  rates.  Any adverse
changes in these factors could cause an impairment in the Partnership's asset.

Revenue Recognition

The Partnership generally leases apartment units for twelve-month terms or less.
Rental income  attributable to leases is recognized  monthly as it is earned and
the Partnership  fully reserves all balances  outstanding  over thirty days. The
Partnership will offer rental concessions during  particularly slow months or in
response  to  heavy  competition  from  other  similar  complexes  in the  area.
Concessions are charged to income as incurred.

ITEM 3.     CONTROLS AND PROCEDURES

The principal  executive officer and principal financial officer of the Managing
General Partner, who are the equivalent of the Partnership's principal executive
officer and principal financial officer,  respectively,  have, within 90 days of
the filing date of this quarterly  report,  evaluated the  effectiveness  of the
Partnership's  disclosure  controls and  procedures  (as defined in Exchange Act
Rules 13a-14(c) and 15d-14(c)) and have determined that such disclosure controls
and  procedures  are  adequate.  There have been no  significant  changes in the
Partnership's  internal  controls or in other  factors that could  significantly
affect the  Partnership's  internal  controls since the date of evaluation.  The
Partnership does not believe any significant deficiencies or material weaknesses
exist in the Partnership's internal controls. Accordingly, no corrective actions
have been taken.

                           PART II - OTHER INFORMATION


ITEM 1.     LEGAL PROCEEDINGS

In March 1998, several putative unit holders of limited partnership units of the
Partnership  commenced an action  entitled  Rosalie  Nuanes,  et al. v. Insignia
Financial Group, Inc., et al. (the "Nuanes action") in the Superior Court of the
State of  California  for the  County  of San  Mateo.  The  plaintiffs  named as
defendants,  among others,  the  Partnership,  its Managing  General Partner and
several of their  affiliated  partnerships  and corporate  entities.  The action
purports  to  assert  claims  on  behalf  of a class  of  limited  partners  and
derivatively  on behalf  of a number  of  limited  partnerships  (including  the
Partnership)  which are named as nominal  defendants,  challenging,  among other
things,  the  acquisition  of  interests  in certain  Managing  General  Partner
entities by Insignia Financial Group, Inc. ("Insignia") and entities which were,
at one  time,  affiliates  of  Insignia;  past  tender  offers  by the  Insignia
affiliates to acquire limited partnership units;  management of the partnerships
by the  Insignia  affiliates;  and the series of  transactions  which  closed on
October 1, 1998 and February 26, 1999 whereby  Insignia and Insignia  Properties
Trust,  respectively,  were merged  into AIMCO.  The  plaintiffs  seek  monetary
damages and equitable relief, including judicial dissolution of the Partnership.
On June 25, 1998, the Managing General Partner filed a motion seeking  dismissal
of the action.  In lieu of responding  to the motion,  the  plaintiffs  filed an
amended  complaint.  The Managing General Partner filed demurrers to the amended
complaint which were heard February 1999.

Pending the ruling on such  demurrers,  settlement  negotiations  commenced.  On
November 2, 1999,  the parties  executed and filed a Stipulation  of Settlement,
settling claims, subject to court approval, on behalf of the Partnership and all
limited partners who owned units as of November 3, 1999. Preliminary approval of
the  settlement  was obtained on November 3, 1999 from the Court,  at which time
the Court set a final  approval  hearing for  December  10,  1999.  Prior to the
December  10,  1999  hearing,  the  Court  received  various  objections  to the
settlement, including a challenge to the Court's preliminary approval based upon
the alleged lack of authority of prior lead counsel to enter the settlement.  On
December 14, 1999, the Managing  General  Partner and its affiliates  terminated
the  proposed  settlement.  In  February  2000,  counsel  for some of the  named
plaintiffs filed a motion to disqualify plaintiff's lead and liaison counsel who
negotiated  the  settlement.  On June  27,  2000,  the  Court  entered  an order
disqualifying  them  from the case and an  appeal  was  taken  from the order on
October 5, 2000. On December 4, 2000, the Court  appointed the law firm of Lieff
Cabraser  Heimann & Bernstein  LLP as new lead  counsel for  plaintiffs  and the
putative class.  Plaintiffs filed a third amended complaint on January 19, 2001.
On March 2, 2001,  the  Managing  General  Partner  and its  affiliates  filed a
demurrer to the third amended  complaint.  On May 14, 2001,  the Court heard the
demurrer to the third amended  complaint.  On July 10, 2001, the Court issued an
order  sustaining  defendants'  demurrer on certain  grounds.  On July 20, 2001,
Plaintiffs filed a motion for reconsideration of the Court's July 10, 2001 order
granting in part and denying in part defendants' demurrer. On September 7, 2001,
Plaintiffs  filed a fourth amended class and  derivative  action  complaint.  On
September 12, 2001, the Court denied Plaintiffs' motion for reconsideration.  On
October 5, 2001, the Managing General Partner and affiliated  defendants filed a
demurrer to the fourth amended complaint,  which was heard on December 11, 2001.
On February 2, 2002,  the Court served its order  granting in part the demurrer.
The  Court has  dismissed  without  leave to amend  certain  of the  plaintiffs'
claims.  On February 11, 2002,  plaintiffs  filed a motion  seeking to certify a
putative  class  comprised of all  non-affiliated  persons who own or have owned
units  in  the  partnerships.   The  Managing  General  Partner  and  affiliated
defendants  oppose the motion.  On April 29,  2002,  the Court held a hearing on
plaintiffs' motion for class  certification and took the matter under submission
after further  briefing,  as ordered by the court, was submitted by the parties.
On July 10, 2002,  the Court entered an order vacating the trial date of January
13, 2003 (as well as the pre-trial and discovery  cut-off  dates) and stayed the
case in its entirety  through November 7, 2002 so that the parties could have an
opportunity  to discuss  settlement.  On October 30, 2002,  the court entered an
order extending the stay in effect through January 10, 2003.

On January 8, 2003,  the parties filed a  Stipulation  of Settlement in proposed
settlement of the Nuanes action and the Heller action  described below. On April
4, 2003, the Court preliminarily approved the settlement and scheduled a hearing
on final approval for June 2, 2003.

In general  terms,  the  proposed  settlement  provides  for  certification  for
settlement  purposes of a settlement class consisting of all limited partners in
this  Partnership and others (the  "Partnerships")  as of December 20, 2002, the
dismissal  with  prejudice  and  release  of claims  in the  Nuanes  and  Heller
litigation,  payment by AIMCO of $9.9  million  (which shall be  distributed  to
settlement  class  members  after  deduction of attorney fees and costs of class
counsel and certain costs of settlement) and up to $1 million toward the cost of
independent  appraisals of the  Partnerships'  properties  by a Court  appointed
appraiser.  An affiliate of the Managing General Partner has also agreed to make
a tender offer to purchase all of the partnership  interests in the Partnerships
within one year of final  approval,  if it is granted,  and to provide  partners
with the  independent  appraisals  at the time of these  tenders.  The  proposed
settlement  also provides for the  limitation  of the allowable  costs which the
Managing  General  Partner or its  affiliates  will charge the  Partnerships  in
connection with this litigation and imposes limits on the class counsel fees and
costs in this litigation.  On April 11, 2003,  notice was distributed to limited
partners providing the details of the proposed settlement.

During the third  quarter of 2001, a complaint  (the "Heller  action") was filed
against  the same  defendants  that are named in the  Nuanes  action,  captioned
Heller v. Insignia Financial Group. On or about August 6, 2001, plaintiffs filed
a first amended  complaint.  The first amended complaint in the Heller action is
brought as a purported  derivative  action,  and asserts  claims for among other
things  breach  of  fiduciary  duty;  unfair  competition;   conversion,  unjust
enrichment;  and judicial  dissolution.  Plaintiffs in the Nuanes action filed a
motion to  consolidate  the Heller action with the Nuanes action and stated that
the Heller action was filed in order to preserve the derivative claims that were
dismissed  without  leave to amend in the Nuanes action by the Court order dated
July 10, 2001. On October 5, 2001, the Managing  General  Partner and affiliated
defendants  moved to strike the first  amended  complaint  in its  entirety  for
violating  the Court's July 10, 2001 order  granting in part and denying in part
defendants'  demurrer in the Nuanes action, or alternatively,  to strike certain
portions of the complaint based on the statute of limitations.  Other defendants
in the action  demurred to the fourth  amended  complaint,  and,  alternatively,
moved to strike the complaint. On December 11, 2001, the court heard argument on
the motions  and took the matters  under  submission.  On February 4, 2002,  the
Court  served  notice of its order  granting  defendants'  motion to strike  the
Heller complaint as a violation of its July 10, 2001 order in the Nuanes action.
On March 27, 2002,  the plaintiffs  filed a notice  appealing the order striking
the  complaint.  Before  completing  briefing on the appeal,  the parties stayed
further proceedings in the appeal pending the Court's review of the terms of the
proposed settlement described above.

Estate of Harry  Schubert v.  National  Property  Investors  4, Civil Action No.
97-09129, Court of Common Pleas of Bucks County, Pennsylvania.  During 1998, the
Plaintiff brought action against the Partnership  alleging that as the result of
carbon monoxide and methane  poisoning due to a malfunctioning  heat unit in the
apartment at the Partnership's property, which was leased by decedent's son, the
decedent lost consciousness for several hours,  suffered respiratory arrest, and
suffered  other pains and injuries.  The Plaintiff  alleges  breach of contract,
fraud,  violations of the Unfair Trade Practices and Consumer Protection Law and
negligence  resulting  in wrongful  death.  This matter is in the  discovery  of
litigation. The Partnership is vigorously defending this matter.

The  Managing  General  Partner  does  not  anticipate  that  any  costs  to the
Partnership, whether legal or settlement costs, associated with these cases will
be material to the Partnership's overall operations.
