                     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 AND PARTNERSHIP MATTERS

         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 nine months  ended  September  30,  2006 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, 2005.

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

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

         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
         income when collected. Interest income is recognized as earned.

                  We accrue for property tax expense  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.  Television,  yellow page, and other  advertising
         expenditures totaled $73,000 and $321,000 for the three and nine months
         ended  September  30,  2006,  respectively,  compared  to  $89,000  and
         $293,000, respectively, for the same periods in 2005.

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

         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  (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:
         ----------------------

                  In accordance with the Financial  Accounting Standards Board's
         Statement No. 130,  "Recording  Comprehensive  Income," at each balance
         sheet date,  the  Partnership  reflects its  marketable  securities  at
         market  value  (based upon their  closing  price on the  balance  sheet
         date), with the difference between the market value and historical cost
         shown as "Other Comprehensive Income" in Partners' Equity.  Adjustments
         to market value are reflected as "Change in  Unrealized  Gain (Loss) on
         Marketable Equity Securities" on the Statement of Comprehensive Income.
         When  marketable  securities are disposed of,  comprehensive  income is
         adjusted to reflect the change in market value through the  disposition
         date.  The  realized  gain is then  reflected  in net income,  and as a
         reduction to Other Comprehensive Income.

                  In accordance with this policy,  the Partnership has reflected
         adjustments  to  unrealized  gains  for the  change  in  market  price,
         reflecting an increase in cumulative unrealized gains of $8,000 for the
         nine months ended September 30, 2006, as compared to an increase in the
         cumulative  unrealized  gains of  $463,000  for the nine  months  ended
         September 30, 2005.

                  Marketable securities consist of 624 shares of common stock of
         Public  Storage,  Inc. and 12,412  depositary  shares of Equity  Stock,
         Series A, of Public  Storage,  Inc.,  at both  September  30,  2006 and
         December 31, 2005. All of the Partnership's  marketable  securities for
         all periods have been designated as available-for-sale.

                  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
         this  transaction,   the  Partnership   recorded  a  realized  gain  of
         $15,633,000  during  the  first  quarter  of  2005,   representing  the
         difference  between the closing  market price on March 31, 2005 and the
         weighted  average  historical  cost  of the  securities  disposed.  The
         limited  and  general  partner's  share  of this  distribution  totaled
         approximately   $16,123,000   ($403.08   per  unit)   and   $5,591,000,
         respectively.  The limited and general  partners' share of the realized
         gain attributable to this transaction totaled approximately $10,102,000
         ($252.55 per unit) and $5,531,000, respectively.

         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 September 30, 2006.

                     NOTES TO CONDENSED FINANCIAL STATEMENTS
                                   (UNAUDITED)

                  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.  Except
         as noted below under  "Accounting for Casualties," our evaluations have
         identified no such impairments at September 30, 2006.

                  Any real estate  facility,  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.

         Accounting for Casualties:
         --------------------------

                  Our policy is to record casualty losses or gains in the period
         the  casualty  occurs  equal to the  differential  between (a) the book
         value of assets destroyed and (b) insurance  proceeds,  if any, that we
         expect to receive in accordance with our insurance contracts. Potential
         insurance   proceeds  that  are  subject  to  uncertainties,   such  as
         interpretation of deductible  provisions of the governing agreements or
         the  estimation  of costs of  restoration,  are treated as a contingent
         proceeds in accordance with Statement of Financial Accounting Standards
         No.  5  ("SFAS  5"),  and not  recorded  until  the  uncertainties  are
         satisfied.

                  During 2005, we recorded a casualty gain totaling $38,000 as a
         result of physical damage to our facilities  caused by Hurricane Wilma,
         which occurred in the fourth quarter of 2005.  This gain represents the
         excess  of  the  insurance  proceeds  that  we  expect  to  receive  of
         approximately  $41,000 over the aggregate net book values of the assets
         damaged ($3,000). We have incurred  approximately  $130,000 in costs to
         repair damages to our facilities.

         Deferred Revenue
         ----------------

                  Deferred  revenue  totaling  $292,000  at  September  30, 2006
         ($321,000 for at December 31, 2005),  consists of prepaid rents,  which
         are recognized when earned.

         Environmental Cost:
         -------------------

                  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.

         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.

         Recent Accounting Pronouncements and Guidance:
         ----------------------------------------------

                  As of November 13, 2006, there have been no recent  accounting
         pronouncements   and   guidance,   which   were   not   effective   for
         implementation  prior to September 30, 2006, that would have a material
         impact upon  reporting  the  operations  or  financial  position of the
         Partnership.

         Segment Reporting:
         ------------------

                  The  Partnership  only has one  reportable  segment as defined
         within Statement of Financial Accounting Standards No. 131.

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  improvements)  needs to be distributed at least
         quarterly.  For the nine  months  ended  September  30,  2006,  we paid
         distributions to the limited and general partners  totaling  $4,560,000
         ($114.00 per unit) and $1,581,000,  respectively.  Future  distribution
         rates may be adjusted to levels,  which are supported by operating cash
         flow after capital improvements and any other obligations.

4.       PARTNERS' EQUITY

                  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 1986,  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 transactions have no effect on the results
         of operations or distributions to partners.

5.       RELATED PARTY TRANSACTIONS

         Management Agreements and Shared Expenses with Affiliates
         ---------------------------------------------------------

                  The Partnership  has a Management  Agreement with PSI pursuant
         to which PSI operates the self-storage facilities for a fee equal to 6%
         of the  facilities'  gross revenue (as  defined).  For the three months
         ended  September 30, 2006 and 2005, the  Partnership  paid PSI $174,000

                                       8


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

         and $162,000,  respectively,  under this management agreement.  For the
         nine months ended  September 30, 2006 and 2005,  the  partnership  paid
         $509,000 and $480,000, respectively.

                  The  Management  Agreement  between  the  Partnership  and PSI
         provides that the Management  Agreement may be terminated without cause
         upon 60 days written notice by the  Partnership or 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 in March 2001, 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 from Affiliate
         under Performance Agreement" on the Partnership's Statements of Income,
         is the  pre-depreciation net operating income with respect to the Azusa
         Property.  The Partnership recorded a total of $340,000 and $311,000 in
         revenue with respect to the Performance  Agreement for the three months
         ended  September  30, 2006 and 2005,  respectively,  and  $927,000  and
         $848,000  for the nine  months  ended  September  30,  2006  and  2005,
         respectively.

                  The Partnership's  facilities,  along with facilities owned by
         PSI and its  affiliates,  are  managed and  marketed  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. As
         a result, significant components of cost of operations, such as payroll
         costs,  advertising  and  promotion,   data  processing  and  insurance
         expenses  are  shared  and  allocated   among  the   properties   using
         methodologies  meant to  fairly  allocate  such  costs  based  upon the
         related  activities.  The total of such expenses,  substantially all of
         which are included in cost of operations in the accompanying  condensed
         statements  of income,  amounted to $329,000 and $284,000 for the three
         months ended September 30, 2006 and 2005, respectively,  and $1,100,000
         and  $921,000 for the nine months  ended  September  30, 2006 and 2005,
         respectively.

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

                  PSI owns 11,365 Limited  Partnership  Units  ("Units"),  as to
         which PSI has sole voting and dispositive power.

                  Hughes and members of his family  (the  "Hughes  Family")  own
         6,198  Units.  Hughes  owns 5,892  Units,  as to which  Hughes has sole
         voting and dispositive  power,  through a wholly-owned  corporation and
         Tamara Hughes Gustavson, an adult daughter of Hughes, owns 306 Units as
         to which Tamara Hughes Gustavson has sole voting and dispositive power;
         PSI has an option to acquire these 306 Units.

                  In  addition,  there  are  7,299  Units  owned by PS  Orangeco
         Partnerships,   Inc.,  a  corporation   in  which  Hughes  Family  owns
         approximately  48% of the  voting  stock,  PSI owns 46% and  members of
         PSI's management and related individuals own approximately 6%.

         Captive Insurance Activities with PSI
         -------------------------------------

                  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, on the cost method,  and has received no distributions
         during the three years ended December 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  (collectively,  this entity and STOR-Re are referred
         to  as  the  "Captive  Entities").  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 reviewed quarterly.

         Other Activities with PSI
         -------------------------

                  A corporation that reinsures  policies against losses to goods
         stored by tenants in PSI's storage facilities was purchased by PSI from
         Mr. Hughes and members of his family (the "Hughes  Family") on December
         31, 2001.  This  corporation  receives the premiums and bears the risks
         associated with the  re-insurance.  The Partnership  receives an access
         fee from this corporation in return for providing tenant listings. This
         fee is based on number of spaces the Partnership has to rent.  Included
         in other income on our accompanying statements of income for these fees
         are $27,000 and $16,000 for the three months ended  September  30, 2006
         and 2005,  respectively,  and  $82,000  and $48,000 for the nine months
         ended September 30, 2006 and 2005, respectively.

                  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  of PSI receives the revenues and
         bears the cost of the activities.

6.       COMMITMENTS AND CONTINGENCIES

         Legal Proceedings:
         ------------------

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

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

                  The claim in this case is  substantially  similar  to those in
         Henriquez  v.  Public  Storage,  Inc.,  which  was  disclosed  in prior
         reports.  In January 2003, the plaintiff caused the Henriquez action to
         be dismissed.

                  Based upon the  uncertainty  inherent  in any  putative  class
         action, PSI cannot presently  determine the potential damages,  if any,
         or the ultimate  outcome of this  litigation.  On November 3, 2003, the
         court granted PSI's motion to strike the plaintiff's  nationwide  class
         allegations  and to limit any putative  class to  California  residents

         only. In August 2005,  PSI filed a motion to remove the case to federal
         court,  but the case has been  remanded to the Superior  Court.  PSI is
         vigorously  contesting  the claims  upon  which this  lawsuit is based,
         including class certification efforts.

         Brinkley v. Public Storage, Inc. (filed April, 2005) (Superior Court of
         -----------------------------------------------------------------------
         California - Los Angeles County)
         --------------------------------

                  The  plaintiff  sued PSI on  behalf  of a  purported  class of
         California  non-exempt  employees based on various  California wage and
         hour laws and seeking  monetary damages and injunctive  relief.  In May
         2006,  a motion for class  certification  was filed  seeking to certify
         five subclasses. Plaintiff sought certification for alleged meal period
         violations,  rest period  violations,  failure to pay for travel  time,
         failure  to pay  for  mileage  reimbursement,  and for  wage  statement
         violations. In October 2006, the Court declined to certify three out of
         the five subclasses.  The Court did, however,  certify subclasses based
         on alleged  meal  period and wage  statement  violations.  The  maximum
         potential  liability  cannot  presently  be  estimated.  PSI intends to
         vigorously   contest  the  substantive  merits  of  the  two  remaining
         subclasses that were certified.

         Simas v. Public Storage, Inc. (filed January,  2006) (Superior Court of
         -----------------------------------------------------------------------
         California - Orange County)
         ---------------------------

                  The  plaintiff  brings this action  against PSI on behalf of a
         purported  class who  bought  insurance  coverage  at PSI's  facilities
         alleging  that PSI  does  not have a  license  to  offer,  sell  and/or
         transact  storage  insurance.  The action was brought under  California
         Business  and  Professions  Code  Section  17200 and  seeks  retention,
         monetary  damages and  injunctive  relief.  PSI filed a demurrer to the
         complaint.  While the  demurrer  was  pending,  Plaintiff  amended  the
         complaint  to allege a national  class and  claims for unfair  business
         practices, unjust enrichment, money had and received, and negligent and
         intentional  misrepresentation.  PSI renewed its  demurrer and moved to
         strike the national  class  allegations.  The Court  dismissed  all the
         claims with leave to amend, except for the claim for unjust enrichment.
         Based on this  ruling,  the Court  held that the  motion to strike  was
         moot.  Plaintiff  elected not to amend her  complaint  and is therefore
         only proceeding with the claim for unjust enrichment. PSI is vigorously
         contesting  the claims upon which this lawsuit is based,  including any
         efforts for class certification.

                  PSI  and  the  Partnership  are a  party  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 effect 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,"   "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 Item 1A,  "Risk
Factors" in Part II of this Quarterly  Report on Form 10-Q. These risks include,
but are not limited to, the following:  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.

OVERVIEW
- --------

         The  self-storage   industry  is  highly  fragmented  and  is  composed
predominantly  of numerous  local and  regional  operators.  Competition  in the
markets in which we  operate  is  significant  and has  increased  over the past
several years due to  additional  development  of  self-storage  facilities.  We
believe  that the  increase  in  competition  has had a  negative  impact to the
Partnership's  occupancy  levels and rental rates in many markets.  However,  we
believe  that  the   Partnership's   affiliation   with  PSI  provides   several
distinguishing   characteristics   that  enable  the   Partnership   to  compete
effectively with other owners and operators.

         PSI is the largest owner and operator of self-storage facilities in the
United States.  All of PSI's  facilities are operated under the "Public Storage"
brand name,  which we believe is the most recognized and established name in the
self-storage  industry.  Market  concentration  establishes  PSI  as  one of the
dominant  providers of self-storage  space in most markets in which PSI operates
and enables PSI to use a variety of promotional  activities,  such as television
advertising as well as targeted  discounting and referrals,  which are generally
not economically viable to most of PSI's competitors.

         We will  continue  to focus our  growth  strategies  on  improving  the
operating performance of our existing self-storage  properties primarily through
increases in revenues  achieved  through the  telephone  reservation  center and
associated  marketing  efforts.  We expect future  increases in rental income to
come  primarily  from  increases  in  realized  rent,  although  there can be no
assurance.

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

         IMPAIRMENT 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 identified no
such  impairments at September 30, 2006.  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.

                                       12



         ESTIMATED USEFUL LIVES OF LONG-LIVED ASSETS

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

         ACCRUALS FOR CONTINGENCIES

         We are exposed to business  and legal  liability  risks with respect to
events that have occurred,  but in accordance with generally accepted accounting
principles  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  result  of  pending
litigation  could  result  in  such  potential  losses  becoming   probable  and
estimable,  which  could  have a  material,  adverse  impact  on  our  financial
condition or results of operations. Some of these potential losses, which we are
aware  of,  are  described  in  Notes  5 and 6 to  the  Partnership's  condensed
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,  the timing of the  recognition  of our expenses  could be incorrect.
Cost of operations,  interest expense,  general and administrative  expense,  as
well as television, yellow page, and other advertising expenditures are expensed
as incurred.

RESULTS OF OPERATIONS

THREE MONTHS ENDED SEPTEMBER 30, 2006 COMPARED TO THREE MONTHS ENDED SEPTEMBER
30, 2005:

         Our net  income  for the three  months  ended  September  30,  2006 was
$2,306,000 compared to $2,140,000 for the three months ended September 30, 2005,
representing an increase of $166,000 or 8%.

         Rental  income  for the  three  months  ended  September  30,  2006 was
$2,905,000 compared to $2,708,000 for the three months ended September 30, 2005,
representing  an increase of $197,000 or 7%. 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 90% and 91% for the three months ended  September  30, 2006 and
2005,  respectively.  Annualized  realized  rent per  square  foot for the three
months ended  September  30, 2006  increased to $15.82 per occupied  square foot
from $14.65 per occupied  square foot for the three months ended  September  30,
2005.

         Dividend  income was  $10,000  and $8,000  for the three  months  ended
September 30, 2006 and 2005, respectively.

         Cost of operations  (including  management fees paid to affiliate - see
Note 5 to the  condensed  financial  statements)  for  the  three  months  ended
September 30, 2006 was $892,000  compared to $813,000 for the three months ended
September  30,  2005,  representing  an  increase  of $79,000 or  10%,which  was
primarily the result of increases in repair and maintenance, property insurance,
utilities and payroll expense  partially  offset by decreases in advertising and
promotion expenses.

         Depreciation  expense was $96,000 for the three months ended  September
30, 2006  compared to $88,000 for the same period in 2005, an increase of $8,000
or 9%.

                                       13




NINE MONTHS ENDED SEPTEMBER 30, 2006 COMPARED TO NINE MONTHS ENDED SEPTEMBER 30,
2005:

         Our net  income  for the  nine  months  ended  September  30,  2006 was
$6,584,000 compared to $21,987,000 for the nine months ended September 30, 2005,
representing a decrease of $15,403,000.  Net income decreased primarily due to a
gain  on  disposition  of  marketable   securities  of  an  affiliate   totaling
$15,633,000 for the nine months ended September 30, 2005.

         Rental  income  for the  nine  months  ended  September  30,  2006  was
$8,502,000  compared to $7,998,000 for the nine months ended September 30, 2005,
representing  an increase of $504,000 or 6%. 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 91% for each of the nine months  ended  September  30, 2006 and
2005.  Annualized  realized  rent per  square  foot for the  nine  months  ended
September 30, 2006 increased to $15.39 per occupied  square foot from $14.43 per
occupied square foot for the nine months ended September 30, 2005.

         Dividend  income  for the nine  months  ended  September  30,  2006 was
$26,000  compared to $196,000  for the nine months  ended  September  30,  2005.
During  the first  quarter  of 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  5 to the  condensed  financial  statements)  for  the  nine  months  ended
September 30, 2006 was  $2,666,000  compared to  $2,444,000  for the nine months
ended September 30, 2005,  representing an increase of $222,000 or 9%, which was
primarily the result of increases in  advertising  and  promotions,  repairs and
maintenance, property taxes, utilities and management fees expenses.

         Depreciation  expense was $288,000 for the nine months ended  September
30,  2006  compared  to  $270,000  for the same  period in 2005,  an increase of
$18,000 or 7%.

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

         Cash generated from  operations  ($7,168,000  for the nine months ended
September 30, 2006) 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  $4,560,000  ($114.00  per unit) and
$1,581,000,  respectively,  for the nine months ended September 30, 2006. Future
distribution rates will be adjusted to levels,  which are supported by operating
cash flow after capital improvements and any other necessary obligations.

         The Partnership does not anticipate issuing senior  securities,  making
loans to other  persons,  investing in the  securities  of other issuers for the
purpose of exercising  control,  underwriting  the  securities of other issuers,
engaging  in the  purchase  and  sale of  investments,  offering  securities  in
exchange for property,  or repurchasing or otherwise reacquiring its outstanding
securities.  The  partnership  may consider  borrowing  money with the intent of
using the proceeds for distribution to partners.

ITEM 4.  CONTROLS AND PROCEDURES
         -----------------------

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

                                       14



         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.  During the third quarter of 2006, there were no significant  changes
in the  Partnership's  internal  controls  over  financial  reporting  that have
materially  affected,  or  are  reasonably  likely  to  materially  affect,  the
Partnership's internal control over financial reporting.

                                       15




PART II.  OTHER INFORMATION


Item 1.  Legal Proceedings

The information set forth under the heading "Legal Proceedings" in Note 6 to our
condensed financial statements in this Form 10-Q is incorporated by reference in
this Item 1.

ITEM 1A. 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,  2005,  you should  consider  the
following factors in evaluating the Partnership:

         THE GENERAL PARTNERS CONTROL THE PARTNERSHIP AS A GROUP.

         Public  Storage Inc.  and B. Wayne  Hughes are general  partners of the
partnership. In the aggregate, Public Storage Inc., B. Wayne Hughes, and members
of his family control  approximately 62% of the limited partnership units of the
partnership. As a result, this group controls any matters submitted to a vote of
our unitholders, including amending our organizational documents, dissolving the
partnership, or approving other such transactions.

         THE PARTNERSHIP MAY BE SUBJECT TO ADDITIONAL RISKS AS A RESULT OF
         PUBLIC STORAGE'S MERGER WITH SHURGARD STORAGE CENTERS, INC.

         In August 2006,  Public  Storage  completed  the  previously  announced
acquisition of Shurgard Storage Centers, Inc. ("Shurgard"), a publicly held REIT
that has interests in approximately 650 self-storage  facilities  located in the
United States and Europe.

         No change in the financial  interests of the Partnership  occurred as a
result of the Shurgard acquisition. However, because the self-storage facilities
of the  Partnership  and Public Storage are managed by Public  Storage,  and the
self-storage  facilities  owned by  Shurgard  are also  being  managed by Public
Storage  since  completion  of the merger,  the merger could have the  following
potential negative impacts on the Partnership:

o        Difficulties  in  the  integration  of  operations,  technologies,  and
         personnel of Shurgard  could  negatively  impact the  operations of the
         facilities managed by Public Storage, including the Partnership's.

o        Public   Storage's   management   attention  to  the   integration  and
         acquisition of Shurgard could divert attention away from the operations
         of the existing self-storage  portfolio that it manages,  including the
         Partnership's properties.

o        Individual  Partnership  properties  could  experience  a  decrease  in
         move-ins,  reductions  to rental  rates,  declines in occupancy  rates,
         increases  to  promotional  discounts,  or other  negative  impacts  to
         revenues in the short and/or long term due to the competitive impact of
         Public Storage commencing management of the former Shurgard facilities,
         particularly  with  respect to those  facilities  that are close to the
         Partnership's facilities.

         SINCE OUR BUSINESS CONSISTS PRIMARILY OF 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        natural disasters, such as earthquakes;

                                       16



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

o        potential terrorists attacks;

o        the impact of environmental protection laws;

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

o        changes in tax, real estate and zoning laws.

         There is significant competition among self-storage facilities and from
other storage alternatives.  All of our properties are self-storage  facilities,
which  generated  substantially  all of our revenue  for the nine  months  ended
September 30, 2006. 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 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 and operator 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,  whether from
environmental  or microbial  issues,  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
Partnership's  properties  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  proactively  with our  tenants to resolve
moisture  infiltration  and  mold-related  issues,  subject  to our  contractual
limitations on liability for such claims.  However,  we can provide no assurance
that material legal claims  relating to moisture  infiltration  and the presence
of, or exposure to, mold will not arise in the future.

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

         We must comply with the Americans  with  Disabilities  Act and fire and
safety  regulations,   which  can  require  significant  expenditures.  All  our
properties must comply with the Americans with Disabilities Act and with related

                                       17



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.

         DEVELOPMENTS  IN CALIFORNIA  MAY HAVE AN ADVERSE IMPACT ON OUR BUSINESS
AND OPERATING RESULTS AND COULD DECREASE THE VALUE OF OUR ASSETS.

         Approximately  70% of  the  Partnership's  properties  are  located  in
California. California is facing 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,  the  Partnership  could be  adversely  impacted by efforts to reenact
legislation  mandating medical insurance for employees of California  businesses
and members of their families.

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

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

         OUR OWNERSHIP INTEREST 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  insurance  coverage  to  the  Partnership,   PSI,  and
affiliates of PSI for losses  occurring prior to 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  amounts  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.  Financial
data with respect to STOR-Re is included in Note 5 to the Partnership's December
31, 2005 financial statements.
