                     NOTES TO CONDENSED FINANCIAL STATEMENTS
                                   (UNAUDITED)




1.       DESCRIPTION OF THE BUSINESS

         Public Storage Properties IV, Ltd., (the "Partnership") is a publicly
         held limited partnership formed under the California Uniform Limited
         Partnership Act in December 1977. The Partnership raised $20,000,000 in
         gross proceeds by selling 40,000 units of limited partnership interest
         ("Units") in an interstate offering, which commenced in May 1978 and
         completed in November 1978. The general partners in the Partnership are
         Public Storage, Inc. ("PSI") and B. Wayne Hughes ("Hughes").

         The Partnership was formed to engage in the business of developing and
         operating self-storage facilities for personal and business use. The
         Partnership owns 17 self-storage properties in California and Florida.

2.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

         Basis of Presentation:
         ----------------------

         The accompanying unaudited condensed financial statements have been
         prepared in accordance with accounting principles generally accepted in
         the United States of America for interim financial information and with
         instructions to Form 10-Q and Article 10 of Regulation S-X.
         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 management, all adjustments
         (consisting of normal, recurring accruals) necessary for a fair
         presentation have been included. The results of operations for the
         three and six months ended June 30, 2004 are not necessarily indicative
         of the results expected for the full year. 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, 2003.

         Certain amounts previously reported have been reclassified to conform
         to the June 30, 2004 presentation; including amounts pursuant to the
         Performance Agreement (see Note 4).

         Use of Estimates:
         -----------------

         The preparation of the condensed financial statements in conformity
         with accounting principles generally accepted in the United States
         requires management to make estimates and assumptions that affect the
         amounts reported in the condensed financial statements and accompanying
         notes. Actual results could differ from those estimates.

         Allocation of Net Income:
         -------------------------

         The general partners' share of net income consists of amounts
         attributable to their 1% capital contribution and an additional
         percentage of cash flow (as defined) which relates to the general
         partners' share of cash distributions as set forth in the Partnership
         Agreement (See "Ownership Interests by the General Partners" under Note
         4). All remaining net income is allocated to the limited partners.

         Per unit data is based on the weighted average number of the limited
         partnership units (40,000) outstanding during the period.

         Cash and Cash Equivalents:
         --------------------------

         For financial statement purposes, the Partnership considers all highly
         liquid investments purchased with a maturity of six months or less to
         be cash equivalents.

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

         Marketable Securities:
         ----------------------

         Marketable securities at June 30, 2004 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. We have designated our portfolio of
         marketable securities as available for sale. Accordingly, at June 30,
         2004, we have recorded the marketable securities at fair value, based
         upon the closing quoted prices of the securities at June 30, 2004.
         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.

         Comprehensive Income:
         ---------------------

         As of January 1, 1998, the Partnership adopted Statement 130, Reporting
         Comprehensive Income. Statement 130 establishes new rules for the
         reporting and display of comprehensive income and its components;
         however, the adoption of this Statement had no impact on the
         Partnership's net income or shareholders' equity. Statement 130
         requires unrealized gains or losses on the Partnership's
         available-for-sale securities, which prior to adoption were reported
         separately in shareholders' equity, to be included in other
         comprehensive income. The primary impact of this statement for the
         Partnership is to recharacterize unrealized gains or losses in
         shareholders' equity as "other comprehensive income."

         Income Taxes:
         -------------

         Public Storage  Properties  IV, Ltd. is treated as a partnership
         for Federal income tax purposes with the taxable income of the entity
         allocated to each partner in accordance with the partnership agreement.

         Real Estate Facilities and Evaluation of Asset Impairment:
         ----------------------------------------------------------

         Real estate facilities are recorded at cost. Costs associated with the
         development, construction, renovation and improvement of properties are
         capitalized. Interest, property taxes, and other costs associated with
         the development incurred during the construction period are capitalized
         as building cost. Expenditures for repairs and maintenance are charged
         to expense as incurred. Depreciation is computed using the
         straight-line method over the estimated useful lives of the buildings
         and improvements, which are generally between 5 and 25 years. Certain
         real estate facilities have been in service longer than 25 years and
         accordingly such buildings are fully depreciated at June 30, 2004.

         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 or
         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 fair value. Our
         evaluations have identified no such impairments at June 30, 2004.

         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 (less cost to sell) or their carrying
         value.

         Revenue and Expense Recognition:
         --------------------------------

         Rental income, which is generally earned pursuant to month-to-month
         leases for storage space, is recognized as earned. Promotional
         discounts are recognized as a reduction to rental income over the
         promotional period, which is generally during the first month of
         occupancy. Late charges and administrative fees are recognized as
         rental income when collected.

         Property taxes are accrued based upon estimates and historical trends.
         If these estimates are incorrect, the timing of expense recognition
         could be affected.

         Cost of operations, general and administrative expense as well as
         television, yellow page and other advertising expenditures are expensed
         as incurred. Accordingly, the amounts incurred in an interim period may
         not be indicative of amounts to be incurred during a full year. Total
         advertising expenses were $113,000 and $222,000 for the three and six
         months ended June 30, 2004, respectively, compared to $118,000 and
         $215,000, respectively, for the same periods in 2003.

         Environmental Costs:
         --------------------

         The Partnership's policy is to accrue environmental assessments and/or
         remediation costs when it is probable that such efforts will be
         required and the related costs can be reasonably estimated. Although
         there can be no assurance, we are not aware of any environmental
         contamination at any of our facilities, which, individually or in the
         aggregate, would be material to our overall business, financial
         condition or results of operations.

3.       CASH DISTRIBUTIONS

         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. We paid
         distributions to the limited and general partners totaling $2,720,000
         ($68.00 per unit) and $943,000, respectively, for the six month ended
         June 30, 2004. Future distribution rates may be adjusted to levels,
         which are supported by operating cash flow after capital improvements
         and any other necessary obligations.

4.       RELATED PARTY TRANSACTIONS

         Management Agreements and Shared Expenses with Public Storage, Inc.:
         --------------------------------------------------------------------

         The Partnership has a management agreement with PSI pursuant to which
         PSI operates the Partnership's self-storage facilities for a fee equal
         to 6% of the facilities' gross revenue (as defined). For the three
         months ended June 30, 2004 and 2003, the Partnership paid $155,000 and
         $123,000, respectively, pursuant to this management agreement. For the
         six months ended June 30, 2004 and 2003, the Partnership paid $306,000
         and $272,000, respectively. The management agreement between the
         Partnership and PSI may be terminated without cause upon 60 days
         written notice by the Partnership or six months notice by PSI.

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

         A real estate facility 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
         self-storage and industrial space, with the cost of these improvements
         entirely funded 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 with respect to the Azusa Property prior
         to the effective date of the agreement, with an annual increase of the
         greater of a) 1% or b) the percentage increase in net operating income
         achieved at the self-storage facilities managed by PSI in the market in
         which this facility is located (the "Guaranteed Amounts"). Where the
         net operating income earned by the Azusa Property is less than these
         Guaranteed Amounts, PSPUD supplements the Partnership's income. Where
         the amount earned by the Azusa Property exceeds the Guaranteed Amounts,
         the excess is remitted to PSPUD. The costs of all capital improvements
         with respect to the Azusa Property are funded by PSPUD. Included in the
         line item "Revenues under performance agreement" on the Partnership's
         Statements of Income, is the pre-depreciation net operating income with
         respect to the Azusa Property. The Performance Agreement expires on
         December 31, 2015.

         The Partnership's facilities, along with facilities owned by PSI and
         its affiliates, are managed jointly by PSI in order to take advantage
         of scale and other efficiencies. Joint costs are allocated on a
         methodology meant to fairly allocate such costs. Such joint costs
         include supervisory, relief, and administrative personnel costs,
         television advertising expenses, yellow page advertising, data
         processing and insurance. The total of such expenses, which are
         primarily included in cost of operations, amounted to $309,000 and
         $291,000 for the three months ended June 30, 2004 and 2003,
         respectively, and $596,000 and $531,000 for the six months ended June
         30, 2004 and 2003, respectively.


         Ownership in Public Storage Stock:
         ----------------------------------

         Marketable securities at June 30, 2004 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.


         Ownership Interest by the General Partners:
         -------------------------------------------

         PSI and Hughes are general partners of the Partnership. In 1995, Hughes
         contributed his ownership and rights to distributions from the
         Partnership to BWH Marina Corporation II, a corporation wholly-owned by
         Hughes. As such, Hughes continues to act as a general partner of the
         Partnership but does not directly receive any compensation,
         distributions or other consideration from the Partnership.

         The general partners have a 1% interest in the Partnership. In
         addition, the general partners had an 8% interest in cash distributions
         attributable to operations (exclusive of distributions attributable to
         sale and financing proceeds) until the limited partners recovered all
         of their investment. Thereafter, the general partners have a 25%
         interest in all cash distributions (including sale and financing
         proceeds). During 1987, the limited partners recovered all of their
         initial investment. All subsequent distributions are being made 25.75%
         (including the 1% interest) to the general partners and 74.25% to the
         limited partners. Transfers of equity are made periodically to
         reconcile the partners' equity accounts to the provisions of the
         Partnership Agreement. These transfers have no effect on results of
         operations or distributions to partners.

         As of June 30, 2004, Hughes and members of his family own 33.7% of the
         Limited Partnership units. PSI and its affiliates own 29.2% of the
         Limited Partnership units.

         Ownership in STOR-Re:
         ---------------------

         The Partnership has a 1.6% ownership interest in STOR-Re Mutual
         Insurance Corporation ("STOR-Re"), which was formed in 1994 as an
         association captive insurance company, and is controlled by PSI. The
         Partnership accounts for its investment in STOR-Re, which is included
         in other assets, using the cost method, and has not received any
         distributions during 2003 or for the six months ended June 30, 2004.

                                       8


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

         STOR-Re provided limited property and liability insurance coverage to
         the Partnership, PSI, and affiliates for losses occurring during policy
         periods prior to April 1, 2004. An entity wholly owned by PSI has
         succeeded STOR-Re with respect to policy periods subsequent to March
         31, 2004. STOR-Re's liabilities for losses and loss adjustment expenses
         include an amount determined from loss reports and individual cases and
         an amount, based on recommendations from an outside actuary using a
         frequency and severity method, for losses incurred but not reported.
         Determining the liability for unpaid losses and loss adjustment expense
         is based upon estimates and while we believe that the amount is
         adequate, the ultimate loss may be in excess of or less than the
         amounts provided. The methods for making such estimates and for
         establishing the resulting liability are continually reviewed.

5.       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 PSI on behalf of a
         putative class of renters who rented self-storage units from PSI.
         Plaintiff alleges that PSI misrepresented 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, PSI cannot presently determine the potential damages, if any,
         or the ultimate outcome of this litigation. On November 3, 2003, the
         court granted PSI's motion to strike the plaintiff's nationwide class
         allegations and to limit any putative class to California residents
         only. PSI is vigorously contesting the claims upon which this lawsuit
         is based including class certification efforts.

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

         The plaintiffs in this case are suing PSI on behalf of a putative 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. On
         December 1, 2003, the California Court of Appeals affirmed the Supreme
         Court's 2002 denial of plaintiff's motion for class certification. The
         maximum potential liability cannot be estimated, but can only be
         increased if claims are permitted to be brought on behalf of others
         under the California Unfair Business Practices Act. The affirmation of
         denial of class certification does not address the claim under the
         California Unfair Business Practices Act.

         PSI is continuing to vigorously contest the claims in this case and
         intends to resist any expansion beyond the named plaintiffs, including
         by opposing claims on behalf of others under the California Unfair
         Business Practices Act. PSI cannot presently determine the potential
         damages, if any, or the ultimate outcome of this litigation.

         Other Items
         -----------

         PSI and The Partnership are parties to various claims, complaints, and
         other legal actions that have arisen in the normal course of business
         from time to time that are not described above. We believe that it is
         unlikely that the outcome of these other pending legal proceedings
         including employment and tenant claims, in the aggregate, will have a
         material adverse impact upon the operations or financial position of
         the Partnership.

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

         The following should be read in conjunction with the Partnership's
condensed financial statements and notes thereto.

         FORWARD LOOKING STATEMENTS: When used within this document, the words
"expects," "believes," "anticipates," "may," "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 21E 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. We quarterly 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 June 30, 2004. 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: Substantially all 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 5 to the partnership's financial statements.

         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. Cost
of operations, general and administrative expense, as well as television, yellow
page, and other advertising expenditures are expensed as incurred. Accordingly,
the amounts incurred in an interim period may not be indicative of the amounts
to be incurred in a full year.

                                       11


RESULTS OF OPERATIONS


THREE MONTHS ENDED JUNE 30, 2004 COMPARED TO THREE MONTHS ENDED JUNE 30, 2003:

         Our net income for the three months ended June 30, 2004 was $2,016,000
compared to $1,850,000 for the three months ended June 30, 2003, representing an
increase of $166,000 or 9%.

         Rental income for the three months ended June 30, 2004 was $2,581,000
compared to $2,460,000 for the three months ended June 30, 2003, representing an
increase of $121,000 or 5%. These increases are attributable to an increase in
annualized realized rents per square foot and a slight increase in average
occupancy at the Partnership's self-storage facilities. Weighted average
occupancy levels at the self-storage facilities were 92% and 91% for the three
months ended June 30, 2004 and 2003, respectively. Annual realized rent for the
three months ended June 30, 2004 increased to $13.79 per occupied square foot
from $13.20 per occupied square foot for the three months ended June 30, 2003.

         Cost of operations (including management fees paid to affiliate - see
Note 4 to the Financial Statements) for the three months ended June 30, 2004 was
$813,000 compared to $781,000 for the three months ended June 30, 2003,
representing an increase of $32,000 or 4%. The increase in cost of operations
for the three months ended June 30, 2004, is primarily due to increases in
property tax, and management fees, partially offset by a decrease in advertising
and promotion costs.

         Depreciation expense was $184,000 for the three months ended June 30,
2004 compared to $241,000 for the same period in 2003, a decrease of $57,000 or
24%. The decrease in depreciation expense is primarily related to the initial
development costs of buildings for many self-storage facilities becoming fully
depreciated.

SIX MONTHS ENDED JUNE 30, 2004 COMPARED TO SIX MONTHS ENDED JUNE 30, 2003:

         Our net income for the six months ended June 30, 2004 was $3,946,000
compared to $3,695,000 for the six months ended June 30, 2003, representing an
increase of $251,000 or 7%.

         Rental income for the six months ended June 30, 2004 was $5,105,000
compared to $4,857,000 for the six months ended June 30, 2003, representing an
increase of $248,000 or 5%. These increases are attributable to an increase in
annualized realized rents per square foot and an increase in average occupancy
at the Partnership's self-storage facilities. Weighted average occupancy levels
at the self-storage facilities were 91% and 89% for the six months ended June
30, 2004 and 2003, respectively. Annual realized rent for the six months ended
June 30, 2004 increased to $13.69 per occupied square foot from $13.26 per
occupied square foot for the six months ended June 30, 2003.

         Cost of operations (including management fees paid to affiliate - see
Note 4 to the Financial Statements) for the six months ended June 30, 2004 was
$1,635,000 compared to $1,494,000 for the six months ended June 30, 2003,
representing an increase of $141,000 or 9%. The increase in cost of operations
for the six months ended June 30, 2004, is primarily due to increases in
advertising and promotion, property tax, utilities, repairs and maintenance and
management fees.

         Depreciation expense was $382,000 for the six months ended June 30,
2004 compared to $481,000 for the same period in 2003 and decrease of $99,000 or
21%. The decrease in depreciation expense is primarily related to the initial
development costs of buildings for many self-storage facilities becoming fully
depreciated.

LIQUIDITY AND CAPITAL RESOURCES

         Cash flows from operating activities ($4,565,000 for the six months
ended June 30, 2004) have been sufficient to meet all current obligations of the
Partnership.

                                       12




         At June 30, 2004, we held 381,980 shares of common stock and 12,412
shares of Equity Stock, Series A of Public Storage, Inc. with a fair value
totaling $17,899,000 (cost basis of $6,340,000). We recognized $359,000 in
dividends for each of the six months ended June 30, 2004 and 2003.

         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. We paid distributions to
the limited and general partners totaling $2,720,000 ($68.00 per unit) and
$943,000, respectively, for the six months ended June 30, 2004. Future
distribution rates may be adjusted to levels, which are supported by operating
cash flow after capital improvements and any other necessary obligations.

         The Partnership may borrow in the future with the intent of using the
proceeds to finance distributions to the limited and general partners.

ITEM 2A. 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, 2003, 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 29.2% 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.

         DEPENDENCY UPON AUTOMATED PROCESSES.

         We have become increasingly centralized and dependent upon automated
information technology processes. As a result, we could be severely impacted by
a catastrophic occurrence, such as a natural disaster or a terrorist attack.

         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        natural disasters, such as earthquakes;

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.

                                       13


         There is significant competition among self-storage facilities and from
other storage alternatives. Most of our properties are self-storage facilities.
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.

         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 the Partnership has an interest in 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 has 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  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.

         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.

 ITEM 4.  CONTROLS AND PROCEDURES
         -----------------------
         Public Storage, Inc. 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 Rule 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.

         At the end of the period covered by this report, Public Storage, Inc.
carried out an evaluation, under the supervision and with the participation of
the Partnership's management, including Public Storage, Inc.'s Chief Executive
Officer and Chief Financial Officer, of the effectiveness of the design and
operation of the Partnership's disclosure controls and procedures. Based upon
that evaluation, the 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.
