                     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, 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 financial  instruments such as short-term treasury securities or
         investment grade short-term commercial paper to be cash equivalents.

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

         Marketable securities consist of 624 shares of common stock at June 30,
         2005  (381,980 at December  31, 2004) and 12,412  depositary  shares of
         Equity Stock, Series A, of Public Storage,  Inc., at both June 30, 2005
         and December 31, 2004. The  Partnership has 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 records 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 weighted average historical
         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.
         Accordingly,   no  Federal  income  tax  expense  is  recorded  by  the
         Partnership.

         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 June 30, 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 June 30, 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.

         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 $112,000 and $204,000 for the three and six
         months  ended June 30,  2005,  respectively,  compared to $113,000  and
         $222,000, respectively, for the same periods in 2004.

         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.  The
         Partnership  paid  distributions  to the limited  and general  partners
         totaling $3,000,000 ($75.00 per unit) and $1,040,000, respectively, for
         the six months ended June 30, 2005, of which $1,520,000 with respect to
         limited  partners and $527,000 with respect to the general partners was
         accrued but unpaid 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.

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, 2005 and 2004, the Partnership  paid $161,000 and
         $155,000, respectively,  pursuant to this management agreement. For the
         six months ended June 30, 2005 and 2004, the Partnership  paid $318,000
         and  $306,000,  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.

         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 $303,000  and
         $309,000   for  the  three   months  ended  June  30,  2005  and  2004,
         respectively,  and  $547,000 and $596,000 for the six months ended June
         30, 2005 and 2004, respectively.


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

         Marketable  securities at June 30, 2005 consist of 624 shares of common
         stock and 12,412 depositary 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.   Hughes   continues  to  act  as  a  general  partner  of  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, 2005, Hughes and members of his family own approximately
         16% of the limited partnership units. PSI owns approximately 28% of the
         limited partnership units. Approximately 18% 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 six months ended June 30, 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  is owned by PSI. 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. In August 2005,  Public  Storage,
         Inc. filed a motion to remove the case to federal  court.  There can be
         no assurance that this motion will be granted.  Public Storage, Inc. is

         -----------------------------------------------------------------------
         SOUTHERN DISTRICT OF FLORIDA)
         -----------------------------

         The Brinkley  plaintiffs are suing Public Storage,  Inc. on behalf of a
         purported  class of  California  property  managers who claim that they
         were not compensated  for all the hours they worked.  The Brinkley suit
         is based upon California  wage and hour laws. The Inhan  plaintiffs are
         suing Public Storage, Inc. in Florida on behalf of a purported class of
         property  managers  who claim they were not  compensated  for all hours
         worked.  The Inhan suit is based upon the Federal Fair Labor  Standards
         Act. The maximum potential liability cannot be estimated,  but would be
         increased if a class or classes are  certified  or, in  California,  if
         claims  are  permitted  to be  brought  on behalf  of others  under the
         California  Unfair  Business  Practices Act.  Public  Storage,  Inc. is
         vigorously contesting the claims in each case and intends to resist any
         expansion  beyond  the  named  plaintiffs  on the  grounds  of  lack of
         commonality of claims.

         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.

              ---------------------------------------------------------------
              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 June 30, 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  unaudited
         condensed financial statements at June 30, 2005.

              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.

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

THREE MONTHS ENDED JUNE 30, 2005 COMPARED TO THREE MONTHS ENDED JUNE 30, 2004:

       Our net income for the three  months  ended June 30, 2005 was  $2,055,000
 compared to $2,016,000  for the three months ended June 30, 2004,  representing
 an increase of $39,000.

       Rental  income for the three  months  ended June 30, 2005 was  $2,666,000
 compared to $2,581,000  for the three months ended June 30, 2004,  representing
 an increase of $85,000 or 3%. This increase is  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 92% for each of the three  month  periods  ended  June 30,  2005 and 2004.
 Annualized  realized  rent per square foot for the three  months ended June 30,
 2005  increased  to $14.32 per  occupied  square foot from $13.79 per  occupied
 square foot for the three months ended June 30, 2004.

       Dividend  income  for the three  months  ended  June 30,  2005 was $8,000
 compared to $179,000 for the three  months  ended June 30,  2004.  At March 31,
 2005, we distributed  substantially all of our holdings of Public Storage, Inc.
 common stock to unitholders of record as of January 1, 2005.  Accordingly,  the
 Partnership's  dividend  income  with  respect  to those  securities  that were
 distributed to unitholders ceased on 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 June
 30, 2005 was $820,000  compared to $813,000 for the three months ended June 30,
 2004,  representing  an increase of $7,000 which was primarily the result of an
 increase in revenue-based management fees.

       Depreciation expense was $79,000 for the three months ended June 30, 2005
 compared  to $184,000  for the same  period in 2004,  a decrease of $105,000 or
 57%. 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, 2005 COMPARED TO SIX MONTHS ENDED JUNE 30, 2004:

       Our net  income for the six months  ended June 30,  2005 was  $19,847,000
 compared to $3,946,000 for the six months ended June 30, 2004,  representing an
 increase  of  $15,901,000.  Net  income  increased  primarily  due to a gain on
 disposition of marketable securities of an affiliate totaling $15,633,000.

       Rental  income for the six  months  ended  June 30,  2005 was  $5,290,000
 compared to $5,105,000 for the six months ended June 30, 2004,  representing an
 increase  of $185,000 or 4%. The  increase  is  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 each of the six months  ended June 30,  2005 and 2004.  Annualized
 realized rent per square foot for the six months ended June 30, 2005  increased
 to $14.26 per occupied square foot from $13.69 per occupied square foot for the
 six months ended June 30, 2004.

       Dividend  income for the six  months  ended  June 30,  2005 was  $188,000
 compared to $359,000 for the six months ended June 30, 2004. At March 31, 2005,
 we distributed substantially all of our holdings of Public Storage, Inc. common
 stock to  unitholders  of  record  as of  January  1,  2005.  Accordingly,  the
 Partnership's  dividend  income  with  respect  to those  securities  that were
 distributed to unitholders ceased on April 1, 2005.

       Cost of  operations  (including  management  fees paid to affiliate - see
 Note 4 to the condensed financial statements) for the six months ended June 30,
 2005 was  $1,631,000  compared to $1,635,000  for the six months ended June 30,
 2004,  representing  a decrease of $4,000 which was the result of lower repairs
 and  maintenance  expense  partially  offset by an  increase  in revenue  based
 management fees.

       Depreciation  expense was $182,000 for the six months ended June 30, 2005
 compared  to $382,000  for the same  period in 2004,  a decrease of $200,000 or
 52%. The decrease in depreciation  expense is primarily  related to the initial
 development costs of buildings for many self-storage  facilities becoming fully
 depreciated.


                                       12





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

       Cash generated from operations  ($4,606,000 for the six months ended June
 30,  2005)  have  been  sufficient  to  meet  all  current  obligations  of the
 Partnership.

       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  $3,000,000  ($75.00 per unit) and
 $1,040,000,  respectively,  for the six  months  ended  June 30,  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.

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 AND COULD TAKE ACTIONS ADVERSE TO OTHER UNITHOLDERS.

       As of June 30, 2005,  Hughes and members of his family own  approximately
 16% of the limited partnership units. PSI owns approximately 28% of the limited
 partnership units. Approximately 18% 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,  and could take  actions  that may not be  favorable to the other
 unitholders.

       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


                                       14





 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.

       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 Public Storage, Inc.'s 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


                                       15





 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.
