                       PUBLIC STORAGE PROPERTIES IV, LTD.
                     NOTES TO CONDENSED FINANCIAL STATEMENTS
                                   (UNAUDITED)




1.       The accompanying  unaudited  condensed  financial  statements have been
         prepared  pursuant to the rules and  regulations  of the Securities and
         Exchange  Commission.  Certain  information  and  footnote  disclosures
         normally included in financial  statements  prepared in accordance with
         generally accepted accounting principles have been condensed or omitted
         pursuant to such rules and regulations,  although  management  believes
         that  the  disclosures  contained  herein  are  adequate  to  make  the
         information   presented  not  misleading.   These  unaudited  condensed
         financial  statements  should be read in conjunction with the financial
         statements and related notes appearing in the  Partnership's  Form 10-K
         for the year ended December 31, 2002.

2.       In the opinion of  management,  the  accompanying  unaudited  condensed
         financial  statements  reflect all  adjustments,  consisting  of normal
         accruals,  necessary  to  present  fairly the  Partnership's  financial
         position at September 30, 2003,  the results of its  operations for the
         three and nine months  ended  September  30, 2003 and 2002 and its cash
         flows for the nine months then ended.

3.       The results of operations for the three and nine months ended September
         30, 2003 are not necessarily indicative of the results expected for the
         full year.

4.       Marketable  securities at September 30, 2003 consist of 381,980  shares
         of common stock and 12,412 shares of Equity  Stock,  Series A of Public
         Storage,  Inc. ("PSI"),  a publicly traded real estate investment trust
         and a  general  partner  of the  Partnership.  We have  designated  our
         portfolio of marketable securities as available for sale.  Accordingly,
         at September 30, 2003, we have  recorded the  marketable  securities at
         fair value,  based upon the closing  quoted prices of the securities at
         September 30, 2003.  Changes in market value of  marketable  securities
         are  reflected  as  unrealized  gains or losses  directly in  Partners'
         Equity and accordingly have no effect on net income.

5.       The Partnership Agreement requires that cash available for distribution
         (cash flow from all sources less cash necessary for any  obligations or
         capital  improvement  needs) be  distributed at least  quarterly.  Cash
         distributions  were  suspended  since the third quarter of 1991 through
         the fourth  quarter of 2001, in order to build cash reserves for future
         debt  service  payments.  As all debt service was repaid as of December
         31,  2001,  the  Partnership   resumed  with  quarterly   distributions
         beginning in the first  quarter of 2002. We paid  distributions  to the
         limited and general partners totaling $4,080,000 ($102.00 per unit) and
         $1,415,000, respectively, for the nine months ended September 30, 2003.
         We paid  distributions  to the limited and  general  partners  totaling
         $4,160,000  ($104.00 per unit) and  $1,443,000,  respectively,  for the
         nine months ended September 30, 2002. Future  distribution rates may be
         adjusted to levels which are  supported  by  operating  cash flow after
         capital improvements and any other necessary obligations.

6.       We evaluate our real estate for  impairment  on a quarterly  basis.  We
         first evaluate  these assets for indicators of impairment  such as a) a
         significant  decrease  in  the  market  price  of  real  estate,  b)  a
         significant adverse change in the extent or manner in which real estate
         is being used or in its physical  condition,  c) a significant  adverse
         change in legal  factors or the business  climate that could affect the
         value of the real estate, d) an accumulation of costs  significantly in
         excess  of the  amount  originally  projected  for the  acquisition  of
         construction  of the real estate,  or e) a current period  operating or
         cash flow loss combined with a history of operating or cash flow losses
         or  a  projection  or  forecast  that  demonstrates  continuing  losses
         associated with the use of the real estate. When any such indicators of
         impairment are noted,  we compare the carrying value of the real estate
         to the future  estimated  undiscounted  cash flows  attributable to the
         real estate. If the real estate's  recoverable  amount is less than the
         carrying  value of the asset,  then an impairment  charge is booked for
         the excess of  carrying  value over the real  estate's  net  realizable
         value. Our evaluations  identified no such impairments at September 30,
         2003.

         Any real  estate  which we expect to sell or  dispose of prior to their
         previously  estimated  useful  life are  stated  at the  lower of their
         estimated net realizable  value or their carrying  value,  less cost to
         sell, and are evaluated throughout the sale process for impairment.

7.       Related Party Transactions

         The Partnership has a Management Agreement with PSI. Under the terms of
         the  agreement,  PSI operates the  mini-warehouse  facilities for a fee
         equal to 6% of the facilities' monthly gross revenue (as defined).  For
         the nine months ended September 30, 2003 and 2002, the Partnership paid
         PSI $536,000 and $497,000,  respectively,  pursuant to this  management
         agreement.

         The Management  Agreement between the Partnership and PSI provides that
         the Management  Agreement may be terminated  without cause upon 60 days
         written notice by the Partnership or nine months notice by PSI.

         One of the real estate  facilites owned by the Partnership  (the "Azusa
         Property")  is  operated  pursuant  to  a  management  and  performance
         agreement (the "Performance  Agreement") with Public Storage Pickup and
         Delivery, LP ("PSPUD"), a subsidiary of PSI. Following the commencement
         of the  Performance  Agreement,  the  facility  was modified to include
         miniwarehouse and industrial space, with the cost of these improvements
         funded entirely by PSPUD.  The industrial space was constructed for use
         in PSPUD's containerized storage operations.

         Under the  Performance  Agreement,  the  Partnership  is  guaranteed to
         receive  the same net  operating  income  it  received  from the  Azusa
         Property  prior to the effective  dates of the  agreement,  with annual
         increases of the greater of a) 1% or b) the percentage  increase in net
         operating  income achieved at the stabilized  miniwarehouse  facilities
         managed by PSI in the market in which this  facility is located.  Where
         the net operating  income earned by the Azusa Property is less than the
         guaranteed amount,  PSPUD supplements the partnership's  income.  Where
         the amount earned by the Azusa Property exceeds the guaranteed  amount,
         the excess is remitted to PSPUD. The costs of all capital  improvements
         with respect to the Azusa Property are funded by PSPUD.

         The revenues  and  expenses,  respectively,  of the  miniwarehouse  and
         containerized  storage  operations are included in "Rental  Income" and
         "Cost of  Operations,"  respectively,  with the net  payment or receipt
         from PSPUD classified as an increase or decrease to rental income.  The
         Partnership   recorded   a  total   of   $277,000   and   $762,000   in
         pre-depreciation  net  income  for the  three  and  nine  months  ended
         September 30, 2003, respectively,  as compared to $268,000 and $755,000
         in  pre-depreciation  net  income for the same  periods  in 2002,  with
         respect to the Azusa Property.

         Marketable  securities at September 30, 2003 consist of 381,980  shares
         of common stock and 12,412 shares of Equity  Stock,  Series A of Public
         Storage,  Inc., a publicly  traded real estate  investment  trust and a
         general partner of the Partnership.

         In addition,  the Partnership  combines its insurance  purchasing power
         with PSI through a captive insurance company controlled by PSI, STOR-Re
         Mutual  Insurance  Corporation  ("Stor-Re").  Stor-Re  provides limited
         property and liability  insurance to the  Partnership  at  commercially
         competitive  rates.  The Partnership and PSI also utilize  unaffiliated
         insurance  carriers to provide  property  and  liability  insurance  in
         excess of Stor-Re's limitations.

8.       Commitments and Contingencies

         Legal Proceedings

         Serrao v. Public  Storage,  Inc.  (filed April 2003)  (Superior Court -
         Orange County)
         -----------------------------------------------------------------------

         The  plaintiff  in this case  filed a suit  against  Public  Storage on
         behalf of a putative  class of renters  who rented  self-storage  units
         from  Public   Storage.   Plaintiff   alleges   that   Public   Storage
         misrepresents  the size of its storage units,  has brought claims under
         California  statutory  and common law relating to consumer  protection,
         fraud,  unfair  competition,  and negligent  misrepresentation,  and is
         seeking monetary damages,  restitution,  and declaratory and injunctive
         relief.

         The claim in this case is  substantially  similar to those in Henriquez
         v. Public  Storage,  Inc.,  which was  disclosed in prior  reports.  In
         January  2003,  the  plaintiff   caused  the  Henriquez  action  to  be
         dismissed.  Based upon the  uncertainty  inherent in any putative class
         action,   Public  Storage  cannot  presently  determine  the  potential
         damages,  if any, or the ultimate  outcome of this  litigation.  Public
         Storage is vigorously  contesting the claims upon which this lawsuit is
         based.

         Salaam, et. al. v. Public Storage, Inc. (filed February 2000) (Superior
         Court - Los Angeles County)
         -----------------------------------------------------------------------

         The  plaintiffs  in this case are suing  Public  Storage on behalf of a
         purported class of California resident property managers who claim that
         they were not  compensated  for all the hours  they  worked.  The named
         plaintiffs  have indicated that their claims total less than $20,000 in
         aggregate.  This maximum potential  liability cannot be estimated,  but
         can  only be  increased  if a  class  is  certified  or if  claims  are
         permitted  to be brought on behalf of the others  under the  California
         Unfair  Business  Practices  Act.  The  plaintiffs'  motion  for  class
         certification  was denied in August 2002; the plaintiffs  have appealed
         this  denial.  This  denial  does not deal  with the  claim  under  the
         California Unfair Business Practices Act.

         Public  Storage is continuing to vigorously  contest the claims in this
         case and intends to resist any expansion beyond the named plaintiffs on
         the  grounds  of  lack  of  commonality  of  claims.  Public  Storage's
         resistance will include opposing the plaintiffs'  appeal of the court's
         denial  of class  certification  and  opposing  the  claim on behalf of
         others under the  California  Unfair  Business  Practices  Act.  Public
         Storage cannot presently  determine the potential  damages,  if any, or
         the ultimate outcome of this litigation.

         The  Partnership is a party to various  claims,  complaints,  and other
         legal  actions that have arisen in the normal  course of business  from
         time to time. The Partnership  believes that the outcome of these other
         pending legal proceedings,  in the aggregate,  will not have a material
         adverse  effect  upon  the  operations  or  financial  portion  of  the
         Partnership.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS


FORWARD LOOKING STATEMENTS
- --------------------------

         When  used  within  this  document,  the words  "expects,"  "believes,"
"anticipates,"  "should,"  "estimates," and similar  expressions are intended to
identify "forward-looking statements" within the meaning of that term in Section
27A of the  Securities  Exchange Act of 1933, as amended,  and in Section 21F of
the Securities Exchange Act of 1934, as amended. Such forward-looking statements
involve known and unknown risks,  uncertainties,  and other  factors,  which may
cause the actual  results and  performance  of the  Partnership to be materially
different  from those  expressed or implied in the forward  looking  statements.
Such factors are described in "Risk  Factors" (as  discussed  below) and include
changes  in  general  economic  conditions  and  in the  markets  in  which  the
Partnership operates and the impact of competition from new and existing storage
and  commercial  facilities and other storage  alternatives,  which could impact
rents and occupancy levels at the  Partnership's  facilities;  the impact of the
regulatory  environment  as  well  as  national,   state,  and  local  laws  and
regulations,  which  could  increase  the  Partnership's  expense and reduce the
Partnership's cash available for distribution;  and economic  uncertainty due to
the impact of war or terrorism  could  adversely  affect our business  plan.  We
disclaim  any  obligation  to publicly  release the results of any  revisions to
these   forward-looking   statements   reflecting  new   estimates,   events  or
circumstances after the date of this report.

CRITICAL ACCOUNTING POLICIES
- ----------------------------

         Impairment of Long Lived Assets

         Substantially  all of our assets consist of real estate. On a quarterly
basis, we evaluate our real estate for impairment. The evaluation of real estate
for impairment  requires  determining  whether  indicators of impairment  exist,
which is a subjective process.  When any indicators of impairment are found, the
evaluation then entails  projections of future operating cash flows,  which also
involves  significant  judgment.  We  have  identified  no such  impairments  at
September 30, 2003.  However,  future events,  or facts and  circumstances  that
currently exist that we have not yet  identified,  could cause us to conclude in
the future that our real estate is impaired. Any resulting impairment loss could
have a  material  adverse  impact on our  financial  condition  and  results  of
operations.

         Estimated Useful Lives of Long-Lived Assets

         A significant  amount of our assets consist of depreciable,  long-lived
assets. We record  depreciation  expense with respect to these assets based upon
their estimated  useful lives. Any change in the estimated useful lives of those
assets,  caused by functional or economic  obsolescence or other factors,  could
have a  material  adverse  impact  on our  financial  condition  or  results  of
operations.

         Accruals for Contingencies

         We are exposed to business  and legal  liability  risks with respect to
events that have occurred,  but in accordance with generally accepted accounting
principles we have not accrued for such potential  liabilities  because the loss
is either  not  probable  or not  estimable  or  because we are not aware of the
event.  Future events and the result of pending  litigation could result in such
potential  losses becoming  probable and estimable,  which could have a material
adverse  impact on our  financial  condition or results of  operations.  Some of
these  potential  losses  which we are aware of, are  described in Note 8 to the
Partnership's financial statements.


                                       9





         Accruals for Operating Expenses

         We accrue for property tax expense and other  operating  expenses based
upon estimates and historical trends and current and anticipated local and state
government  rules  and  regulations.  If these  estimates  and  assumptions  are
incorrect, our expenses could be misstated.

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

         Three months ended  September  30, 2003  compared to three months ended
September 30, 2002:

         Our net  income  for the three  months  ended  September  30,  2003 was
$1,995,000 compared to $1,862,000 for the three months ended September 30, 2002,
representing an increase of $133,000, or 7%.

         Rental  income  for the  three  months  ended  September  30,  2003 was
$3,062,000 compared to $2,651,000 for the three months ended September 30, 2002,
representing an increase of $411,000 or 16%. These increases are attributable to
an increase in average occupancy at the Partnership's mini-warehouse facilities.
Weighted average occupancy levels at the mini-warehouse  facilities were 94% and
87% for the three months ended September 30, 2003 and 2002, respectively. Annual
realized rent for the three months ended  September 30, 2003 increased to $13.44
per  occupied  square  foot from $13.32 per  occupied  square foot for the three
months ended September 30, 2002.

         Cost of operations  (including  management  fees paid to affiliate) for
the three months ended  September 30, 2003 was  $1,007,000  compared to $803,000
for the three  months ended  September  30,  2002,  representing  an increase of
$204,000 or 25%. The increase in cost of  operations  for the three months ended
September 30, 2003, is primarily  due to increases in payroll,  advertising  and
promotion and property insurance costs.

         In  addition,   revenues  and  cost  of  operations  increased  at  the
Partnership Facility that offers containerized  storage,  however,  there was no
material impact to net operating income.

         Nine months  ended  September  30, 2003  compared to nine months  ended
September 30, 2002:

         Our net  income  for the  nine  months  ended  September  30,  2003 was
$5,690,000  compared to $5,620,000 for the nine months ended September 30, 2002,
representing an increase of $70,000 or 1%.

         Rental  income  for the  nine  months  ended  September  30,  2003  was
$8,932,000  compared to $8,278,000 for the nine months ended September 30, 2002,
representing an increase of $654,000 or 8%. These increases are  attributable to
an increase in average occupancy at the Partnership's mini-warehouse facilities.
Weighted average occupancy levels at the mini-warehouse  facilities were 93% and
87% for the nine months ended September 30, 2003 and 2002, respectively.  Annual
realized rent for the nine months ended  September 30, 2003  increased to $13.24
per occupied  square foot  compared to $13.05 per  occupied  square foot for the
nine months ended September 30, 2002.

         Cost of operations  (including  management  fees paid to affiliate) for
the nine months ended  September 30, 2003 was $3,038,000  compared to $2,549,000
for the nine  months  ended  September  30,  2002,  representing  an increase of
$489,000 or 19%.  The increase in cost of  operations  for the nine months ended
September 30, 2003, is primarily  due to increases in payroll,  advertising  and
promotion and property insurance costs.

         In  addition,   revenues  and  cost  of  operations  increased  at  the
Partnership Facility that offers containerized  storage,  however,  there was no
material impact to net operating income.

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

         Cash flows from operating  activities  ($6,827,000  for the nine months
ended September 30, 2003) have been  sufficient to meet all current  obligations
of the Partnership.


                                       10





         The Partnership Agreement requires that cash available for distribution
(cash flow from all sources less cash  necessary for any  obligations or capital
improvement  needs) be distributed at least quarterly.  Cash  distributions have
been  suspended  since the third quarter of 1991 in order to build cash reserves
for future debt service payments.  As all debt service was repaid as of December
31, 2001, the Partnership resumed with quarterly  distributions beginning in the
first quarter of 2002. We paid distributions to the limited and general partners
totaling  $4,080,000  ($102.00 per unit) and $1,415,000,  respectively,  for the
nine months ended September 30, 2003. We paid  distributions  to the limited and
general  partners  totaling   $4,160,000  ($104.00  per  unit)  and  $1,443,000,
respectively,  for the nine months ended September 30, 2002. Future distribution
rates may be adjusted to levels which are supported by operating cash flow after
capital improvements and any other necessary obligations.

RISK FACTORS
- ------------

         In addition to the other information in our Form 10-Q and Annual Report
on Form 10-K for the year ended  December  31,  2002,  you should  consider  the
following factors in evaluating the Partnership:

         PUBLIC   STORAGE  HAS  A   SIGNIFICANT   DEGREE  OF  CONTROL  OVER  THE
PARTNERSHIP.

         Public Storage is general partner and owns  approximately  33.2% of our
outstanding  limited partnership units. In addition,  PS Orangeco  Partnerships,
Inc.,  an  affiliate  of  Public  Storage,  owns  an  additional  18.2%  of  our
outstanding  limited  partnership  units.  As a  result,  Public  Storage  has a
significant  degree  of  control  over  matters  submitted  to  a  vote  of  our
unitholders,  including  amending our organizational  documents,  dissolving the
Partnership and approving other extraordinary transactions.

         SINCE OUR BUSINESS  CONSISTS  PRIMARILY OF ACQUIRING AND OPERATING REAL
ESTATE, WE ARE SUBJECT TO REAL ESTATE OPERATING RISKS.

         The value of our  investments  may be reduced by general  risks of real
estate  ownership.  Since we derive  substantially  all of our income  from real
estate  operations,  we  are  subject  to  the  general  risks  of  owning  real
estate-related assets, including:

o        lack of demand for rental spaces or units in a locale;

o        changes in general economic or local conditions;

o        changes in supply of or demand for similar or competing  facilities  in
         an area;

o        potential terrorists attacks;

o        the impact of environmental protection laws;

o        changes in interest rates and availability of permanent  mortgage funds
         which may  render the sale or  financing  of a  property  difficult  or
         unattractive; and

o        changes in tax, real estate and zoning laws.

         There is significant competition among self-storage facilities and from
other storage alternatives.  Most of our properties are self-storage facilities,
which generated 87% of our rental revenue during 2003.  Local market  conditions
will play a significant part in how competition  will affect us.  Competition in
the  market  areas  in which  many of our  properties  are  located  from  other
self-storage  facilities and other storage  alternatives  is significant and has
affected the occupancy  levels,  rental rates and operating  expenses of some of
our  properties.  Any increase in  availability  of funds for investment in real
estate  may  accelerate   competition.   Further   development  of  self-storage
facilities may intensify competition among operators of self-storage  facilities
in the market areas in which we operate.


                                       11





         We may incur  significant  environmental  costs and liabilities.  As an
owner of real properties,  under various federal,  state and local environmental
laws, we are required to clean up spills or other releases of hazardous or toxic
substances  on  or  from  our  properties.  Certain  environmental  laws  impose
liability whether or not the owner knew of, or was responsible for, the presence
of the  hazardous  or toxic  substances.  In some  cases,  liability  may not be
limited to the value of the property.  The presence of these substances,  or the
failure to properly  remediate any resulting  contamination,  also may adversely
affect the owner's or operator's  ability to sell, lease or operate its property
or to borrow using its property as collateral.

         We  have  conducted  preliminary   environmental   assessments  on  the
properties   in  which  the   Partnership   has  an  interest  to  evaluate  the
environmental condition of, and potential  environmental  liabilities associated
with, our properties. These assessments generally consist of an investigation of
environmental  conditions at the property  (not  including  soil or  groundwater
sampling or analysis),  as well as a review of available  information  regarding
the site and publicly available data regarding  conditions at other sites in the
vicinity.  In connection with these property  assessments,  we have become aware
that prior  operations or activities at some facilities or from nearby locations
have or may have resulted in  contamination  to the soil or groundwater at these
facilities.  In this regard, some of our facilities are or may be the subject of
federal or state environment  investigations  or remedial  actions.  Although we
cannot  provide  any   assurance,   based  on  the   preliminary   environmental
assessments,  we believe we have funds  available  to cover any  liability  from
environmental  contamination or potential  contamination and we are not aware of
any  environmental  contamination  of our  facilities  material  to our  overall
business, financial condition or results of operation.

         There have been an increasing  number of claims and litigation  against
owners and  managers of rental  properties  relating  to moisture  infiltration,
which can result in mold or other property  damage.  When we receive a complaint
concerning  moisture  infiltration,  condensation or mold problems and/or become
aware that an air quality concern exists,  we implement  corrective  measures in
accordance  with  guidelines and protocols we have developed with the assistance
of outside  experts.  We seek to work  proactively  with our  tenants to resolve
moisture  infiltration  and  mold-related  issues,  subject  to our  contractual
limitations on liability for such claims. However, we can make no assurance that
material legal claims relating to moisture  infiltration and the presence of, or
exposure to mold will not arise in the future.

         Property   taxes  can  increase  and  cause  a  decline  in  yields  on
investments.  Each of our  properties is subject to real property  taxes.  These
real property  taxes may increase in the future as property tax rates change and
as our properties are assessed or reassessed by tax authorities.  Such increases
could adversely impact the Partnership's profitability.

         We must comply with the Americans  with  Disabilities  Act and fire and
safety  regulations,   which  can  require  significant  expenditures.  All  our
properties must comply with the Americans with Disabilities Act and with related
regulations  (the  "ADA").  The ADA has  separate  compliance  requirements  for
"public accommodations" and "commercial facilities," but generally requires that
buildings be made  accessible to persons with  disabilities.  Various state laws
impose similar  requirements.  A failure to comply with the ADA or similar state
laws could result in government  imposed fines on us and the award of damages to
individuals affected by the failure. In addition, we must operate our properties
in compliance with numerous local fire and safety  regulations,  building codes,
and other land use regulations.  Compliance with these  requirements can require
us to spend  substantial  amounts of money,  which would  reduce cash  otherwise
available  for   distribution   to  Partners.   Failure  to  comply  with  these
requirements could also affect the marketability of our real estate facilities.


                                       12



         TERRORIST  ATTACKS AND THE POSSIBILITY OF WIDER ARMED CONFLICT MAY HAVE
AN ADVERSE  IMPACT ON OUR BUSINESS AND OPERATING  RESULTS AND COULD DECREASE THE
VALUE OF OUR ASSETS.

         Terrorist attacks and other acts of violence or war, such as those that
took place on September 11, 2001,  could have a material  adverse  impact on our
business and operating results. There can be no assurance that there will not be
further  terrorist  attacks  against  the  United  States or its  businesses  or
interests.  Attacks or armed  conflicts that directly  impact one or more of our
properties  could  significantly  affect our ability to operate those properties
and thereby  impair our operating  results.  Further,  we may not have insurance
coverage for losses  caused by a terrorist  attack.  Such  insurance  may not be
available,  or if it is  available  and  we  decide  to  obtain  such  terrorist
coverage,  the cost for the insurance may be significant in  relationship to the
risk  overall.  In  addition,  the adverse  effects  that such  violent acts and
threats of future attacks could have on the U.S.  economy could similarly have a
material  adverse  effect on our  business and results of  operations.  Finally,
further terrorist acts could cause the United States to enter into a wider armed
conflict, which could further impact our business and operating results.

DEVELOPMENTS IN CALIFORNIA MAY HAVE AN ADVERSE IMPACT ON OUR BUSINESS.

         We are  headquartered  in, and 12 of the 17  facilities  we operate are
located in, California. California is facing serious budgetary problems. Actions
that may be taken in response to these problems, such as an increase in property
taxes on commercial properties,  could adversely impact our business and results
of  operations.  In  addition,  we could be  adversely  impacted by the recently
enacted legislation mandating medical insurance for California businesses.

CONTROLS AND PROCEDURES
- -----------------------

         The Partnership  maintains  disclosure controls and procedures that are
designed to ensure that  information  required  to be  disclosed  in reports the
Partnership  files and submits under the Exchange  Act, is recorded,  processed,
summarized and reported within the time periods specified in accordance with SEC
guidelines  and that  such  information  is  communicated  to the  Partnership's
management,  including its Chief Executive Officer and Chief Financial  Officer,
to allow timely decisions  regarding required disclosure based on the definition
of "disclosure  controls and procedures" in Rules 13a-15(e) of the Exchange Act.
In designing and evaluating the disclosure  controls and procedures,  management
recognized  that any controls and  procedures,  no matter how well  designed and
operated, can provide only reasonable assurance of achieving the desired control
objectives  and  management  necessarily  was  required to apply its judgment in
evaluating the cost-benefit  relationship of possible controls and procedures in
reaching that level of reasonable assurance.

         As of the  end of the  fiscal  quarter  covered  by  this  report,  the
Partnership  carried  out an  evaluation,  under  the  supervision  and with the
participation of the Partnership's management, including the Partnership's Chief
Executive  Officer  and  the  Partnership's  Chief  Financial  Officer,  of  the
effectiveness  of the  design  and  operation  of the  Partnership's  disclosure
controls and procedures.  Based upon this evaluation,  the  Partnership's  Chief
Executive  Officer and Chief Financial  Officer concluded that the Partnership's
disclosure controls and procedures were effective.

         There have not been any changes in our internal  control over financial
reporting (as such term is defined in Rules  13a-15(f)  and 15d-15(f)  under the
Exchange  Act) during the fiscal  quarter to which this report  relates that has
materially affected, or are reasonably likely to materially affect, our internal
control over financial reporting.
