                     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 months ended March 31, 2005 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, 2004.

         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 with an original  maturity of three months or less
         to be cash equivalents.

                     NOTES TO CONDENSED FINANCIAL STATEMENTS
                                   (UNAUDITED)

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

         Marketable  securities  consisted of 381,980 shares of common stock at
         December 31, 2004 (624 at March 31, 2005) and 12,412 depositary shares
         of Equity Stock,  Series A, of Public  Storage,  Inc., at December 31,
         2004 and March 31, 2005. The  Partnership had designated its portfolio
         of marketable  securities as being  available-for-sale.  In accordance
         with the  Financial  Accounting  Standard  Board's  Statement No. 130,
         "Reporting   Comprehensive   Income",   the  Partnership  records  the
         marketable  securities  at fair value at each balance  sheet  date,and
         record a  corresponding  unrealized  gain for the excess of the market
         value over the cost of the marketable securities, with a corresponding
         increase to Partnership equity.

         On March 31, 2005, the Partnership  distributed  substantially  all of
         its holdings in Public Storage,  Inc. common stock on a pro rata basis
         to  unitholders  of record as of January  1, 2005.  As a result of the
         disposition of its holdings of Public Storage,  Inc. common stock, the
         Partnership recorded a gain of $15,633,000 during the first quarter of
         2005,  representing  the difference  between the March 31, 2005 market
         value of the marketable securities and the historical cost (calculated
         using weighted average cost).

         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 the original  development cost of such buildings are fully
         depreciated at March 31, 2005.

         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 March 31, 2005.

         Any real  estate  which we expect to sell or  dispose  of prior to its
         previously  estimated  useful  life  is  stated  at the  lower  of its
         estimated  net  realizable  value (less cost to sell) or its  carrying
         value.

                     NOTES TO CONDENSED FINANCIAL STATEMENTS
                                   (UNAUDITED)

         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 $92,000 and $109,000 for the
         three months ended March 31, 2005 and 2004 respectively.

         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.  Future  distribution  rates will be  adjusted to levels to
         levels  which are  supported  by  operating  cash flow  after  capital
         improvements and any other necessary obligations.

         On April 15, 2005, we paid a cash distribution to unitholders totaling
         $2,047,000,  representing cash available for distribution at March 31,
         2005. At March 31, 2005,  management  decided to pay this distribution
         to unitholders.  Accordingly, we have accrued this distribution on our
         March 31, 2005 condensed balance sheet.

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 March 31, 2005 and 2004,  the  Partnership  paid $157,000
         and $151,000, respectively, pursuant to this management agreement. 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.

         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
                                       7


                       PUBLIC STORAGE PROPERTIES IV, LTD.

                                   (UNAUDITED)

         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 $267,000  and
         $287,000  for  the  three  months  ended  March  31,  2005  and  2004,
         respectively.


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

         Marketable securities at March 31, 2005 consist of 624 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 with a significant ownership interest in the Partnership.


         Ownership Interests 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 March 31,  2005,  Hughes and  members of his family own 15.5% of
         the  limited   partnership  units.  PSI  owns  28.4%  of  the  limited
         partnership  units.  An  additional  18.2% of the limited  partnership
         units are owned by PS Orangeco  Partnerships,  Inc., a corporation  in
         which  Hughes and members of his family own  approximately  48% of the
         voting stock, PSI owns 46% and members of PSI's management and related
         individuals own approximately 6%.


         Based on their pro rata  ownership  interests,  PSI and its affiliates
         received  211,023  shares of common stock and Hughes  received  61,448
         shares of common stock in connection  with the  distribution of common
         stock described in Note 2.

         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  2004 or for the three  months  ended  March 31,
         2005.

         STOR-Re provides limited property and liability  insurance coverage to
         the Partnership, PSI, and affiliates for losses occurring before April
         1, 2004.  STOR-Re was succeeded  with respect to these  activities for
         losses  occurring after March 31, 2004 by a wholly owned subsidiary of
         PSI.  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 that is a
         member of the American  Academy of  Actuaries,  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.

         Other Business Activities
         -------------------------

         A corporation  that reinsures  policies against losses to goods stored
         by tenants in the  Partnership's  storage  facilities was purchased by
         PSI from Mr. Hughes and members of his family (the "Hughes Family") on
         December  31,  2001.  We believe  that the  availability  of insurance
         reduces our  potential  liability to tenants for losses to their goods
         from theft or destruction.  This corporation receives the premiums and
         bears the risks associated with the re-insurance of tenant goods.

         A  subsidiary  of PSI sells  locks  and boxes and rents  trucks to the
         general  public and  tenants to be used in securing  their  spaces and
         moving their goods. The subsidiary receives the revenues and bears the
         cost of the activities.  We believe that the availability of locks and
         boxes for sale and the rental of trucks promote the rental of spaces.

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

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

         Public  Storage,  Inc.  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.  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 March 31, 2005.  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
accounting  principles  generally  accepted in the United  States,  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  outcome  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  of which we are  aware  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 MARCH 31, 2005 COMPARED TO THREE MONTHS ENDED MARCH 31, 2004:

     Our net income for the three months  ended March 31, 2005 was  $17,792,000
compared to $1,930,000 for the three months ended March 31, 2004,  representing
an increase of  $15,862,000.  Net income  increased  primarily due to a gain on
disposition of marketable securities of an affiliate totaling $15,633,000.

     Rental  income for the three  months  ended March 31, 2005 was  $2,624,000
compared to $2,524,000 for the three months ended March 31, 2004,  representing
an increase of $100,000 or 4%. These increases are  attributable to an increase
in annualized realized rents per square foot at the Partnership's  self-storage
facilities.  Weighted average  occupancy levels at the self-storage  facilities
were 91% for the  three  months  ended  March  31,  2005 and  2004.  Annualized
realized  rent per  square  foot for the three  months  ended  March  31,  2005
increased  to $14.16 per occupied  square foot from $13.60 per occupied  square
foot for the three months ended March 31, 2004.

     At March 31, 2005,  we  distributed  381,356 of the 381,980  shares of our
holdings of Public  Storage,  Inc.  common  stock held at December  31, 2004 to
unitholders  of record as of  January  1,  2005,  and we  recognized  a gain on
disposition of $15,633,000.  The historical cost of these marketable securities
was $6,081,000.

     Dividends  from our holdings in  marketable  securities  of our  affiliate
amounted to $180,000 for each of the three month  periods  ended March 31, 2005
and 2004 which  included  $172,000 with respect to our 381,980 shares of Public
Storage, Inc. common stock. As discussed above, we distributed 381,356 of these
commons shares to unitholders and, accordingly,  the Partnership will no longer
receive dividends on those 381,356 shares effective April 1, 2005.

     Cost of operations (including management fees paid to affiliate - see Note
4 to the condensed  financial  statements) for the three months ended March 31,
2005 was  $811,000  compared to $822,000  for the three  months ended March 31,
2004,  representing  a  decrease  of  $11,000  which  was the  result  of lower
advertising   expenses  partially  offset  by  an  increase  in  revenue  based
management fees.

     Depreciation  expense was  $103,000  for the three  months ended March 31,
2005 compared to $198,000 for the same period in 2004, a decrease of $95,000 or
48%. 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 for the three months ended March 31,
2005 have been sufficient to meet all current obligations of the Partnership.

     Dividends  from our holdings in  marketable  securities  of our  affiliate
amounted to $180,000 for each of the three month  periods  ended March 31, 2005
and 2004 which  included  $172,000 with respect to our 381,980 shares of Public
Storage, Inc. common stock. As discussed above, we distributed 381,356 of these
commons shares to unitholders and, accordingly,  the Partnership will no longer
receive dividends on those 381,356 shares effective April 1, 2005.

     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.  At March 31, 2005, the
Partnership  accrued,  but did not pay, cash  distributions  to the limited and
general partners. On April 15, 2005, we paid a cash distribution to unitholders
totaling $2,047,000,  representing cash available for distribution at March 31,
2005. Future  distribution rates will be adjusted to levels 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.

                                      12


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,  2004,  you  should  consider  the
following factors in evaluating the Partnership:

         THE GENERAL PARTNERS HAVE A SIGNIFICANT DEGREE OF CONTROL OVER THE
PARTNERSHIP.

     As of March 31,  2005,  Hughes and  members of his family own 15.5% of the
limited  partnership units. PSI owns 28.4% of the limited partnership units. An
additional  18.2% of the  limited  partnership  units are owned by PS  Orangeco
Partnerships, Inc., a corporation in which Hughes and members of his family own
approximately  48% of the  voting  stock,  PSI  owns 46% and  members  of PSI's
management  and related  individuals  own  approximately  6%. As a result,  the
General Partners have 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.


         COMPLIANCE WITH SECTION 404 OF THE SARBANES-OXLEY ACT

     Pursuant  to Section  404 of the  Sarbanes-Oxley  Act of 2002,  we will be
required to include,  in our annual  report  beginning  December 31, 2006,  our
assessment  of  the  effectiveness  of  our  internal  control  over  financial
reporting and our audited  financial  statements as of that date.  Furthermore,
our independent registered public accounting firm will be required to attest to
whether our  assessment  of the  effectiveness  of our  internal  control  over
financial reporting is fairly statement in all material respects and separately
report  on  whether  it  believes  we  maintained,  in all  material  respects,
effective internal control over financial reporting as of December 31, 2006.

     As of March 31, 2005,  PSI, our General  Partner,  has not  completed  our
assessment  of  the  effectiveness  of  our  internal  control  over  financial
reporting.  PSI believes we will meet the requirements of Section 404, however,
if PSI  fails  to  timely  complete  their  assessment,  or if our  independent
registered public accounting firm cannot timely attest to their assessment,  we
could be subject to regulatory sanctions and a loss of public confidence in our
internal  control.  In  addition,  any  failure to  implement  new or  improved
controls, or difficulties  encountered in their  implementation,  could have an
adverse effect on our operating  results or cause us to fail to timely meet our
regulatory reporting obligations.

         INCREASES IN INTEREST RATES MAY ADVERSELY AFFECT THE VALUE OF
PARTNERSHIP UNITS.

     One of the factors that  influence the value of our  partnership  units is
the annual rate of  distributions  that we pay as compared with interest rates.
An increase in interest  rates may lead  purchasers of real estate  partnership
units to demand higher annual  distribution rates, which could adversely affect
the market price of our partnership units.

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

     A majority of our  properties  are located in  California.  California  is
facing  serious  budgetary  problems.  Action  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 efforts to reenact legislation mandating medical
insurance for employees of California businesses and members of their families.

         WE HAVE DEVELOPED A DEPENDENCY UPON AUTOMATED PROCESSES AND THE
INTERNET.

     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. In
addition, a portion of our business operations are conducted over the internet,
increasing the risk of viruses that could cause system failures and disruptions
of operations.

                                      13


         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.

     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.

                                      14


     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.

         OUR OWNERSHIP IN STOR-RE MAY LOSE VALUE OR BECOME A LIABILITY.

     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. STOR-Re provides limited property
and liability coverage to the Partnership, PSI and affiliates of PSI for losses
occurring  before  April 1, 2004.  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  that is a
member of the American  Academy of  Actuaries,  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 amount provided,  which may result in a reduction in the value of
the  Partnership's  investment or could result in future payments to STOR-Re if
its reserves were determined to be inadequate.

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.
                                      15



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.
