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


1.       DESCRIPTION OF THE BUSINESS AND BASIS OF PRESENTATION

                  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,  formerly  Public
         Storage, Inc., ("PS") 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.

                  The accompanying unaudited condensed financial statements have
         been  prepared  by us  pursuant  to the  rules and  regulations  of the
         Securities  and  Exchange  Commission  ("SEC") on the same basis as our
         audited annual  financial  statements  and, in our opinion  reflect all
         adjustments (consisting only of normal recurring adjustments) necessary
         to present fairly the financial information set forth therein.  Certain
         information  and  note  disclosures   normally  included  in  financial
         statements   prepared  in  accordance  with  U.S.   generally  accepted
         accounting  principles have been condensed or omitted  pursuant to such
         rules  and   regulations,   although  we  believe  that  the  following
         disclosures,  when  read in  conjunction  with  the  audited  financial
         statements  and notes thereto as of December 31, 2008,  are adequate to
         make the  information  presented not  misleading.  The  Partnership has
         evaluated  subsequent  events through August 13, 2009, which represents
         the filing date of this Form 10-Q with the SEC. As of August 13,  2009,
         there  were  no  subsequent   events  which  required   recognition  or
         disclosure.

2.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND PARTNERSHIP MATTERS

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

                  The preparation of the financial statements in conformity with
         U.S. generally accepted  accounting  principles  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.  Casualty  losses or gains are  recognized in the
         period the casualty  occurs,  based upon the  differential  between the
         book value of assets destroyed,  and estimated insurance  proceeds,  if
         any,  that we  expect  to  receive  in  accordance  with our  insurance
         contracts.

                       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.

         Financial Instruments:
         ----------------------

                  The  Partnership has estimated the fair value of its financial
         instruments   using  available   market   information  and  appropriate
         valuation   methodologies.   Considerable   judgment   is  required  in
         interpreting   market  data  to  develop  estimates  of  market  value.
         Accordingly,  estimated fair values are not  necessarily  indicative of
         the amounts that could be realized in current market exchanges.

                  For  purposes  of  financial   statement   presentation,   the
         Partnership  considers all highly liquid financial  instruments such as
         short-term treasury securities, money market funds with daily liquidity
         and a rating in excess of AAA by  Standard  and Poor's,  or  investment
         grade short-term  commercial  paper with remaining  maturities of three
         months or less at the date of acquisition to be cash equivalents.

                  Due to  the  short  period  to  maturity  and  the  underlying
         characteristics  of our cash and cash  equivalents,  other assets,  and
         accrued and other  liabilities,  the Partnership  believes the carrying
         values as  presented on the  condensed  balance  sheets are  reasonable
         estimates of fair value.

                  Financial  assets  that are  exposed  to credit  risk  consist
         primarily  of cash  and  cash  equivalents  as well as rent  and  other
         receivables.

         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. At June 30, 2009, all of the real estate facilities have been in
         service longer than 25 years, and accordingly the original  development
         costs of such buildings are fully depreciated.

                  We  evaluate  our real  estate for  impairment  on a quarterly
         basis. We first evaluate these assets for indicators of impairment, and
         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, 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, 2009.

                                       6



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


                  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.

         Deferred Revenue:
         -----------------

                  Deferred revenue totaling  $276,000 at June 30, 2009 ($297,000
         at December 31, 2008),  consists of prepaid rents, which are recognized
         as rental income 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 and state  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 August 13,  2009,  there have been no recent  accounting
         pronouncements   and   guidance,   which   were   not   effective   for
         implementation  prior to June 30,  2009,  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.  During the three months  ended June 30, 2009,  we paid cash
         distributions to the limited and general partners  totaling  $1,480,000
         ($37.00 per unit) and $514,000,  respectively,  and $1,600,000  ($40.00
         per  unit) and  $555,000,  respectively,  for the same  period in 2008.
         During the six months ended June 30, 2009,  we paid cash  distributions
         to the limited and general  partners  totaling  $3,240,000  ($81.00 per
         unit) and $1,124,000,  respectively,  and $3,160,000  ($79.00 per unit)
         and  $1,096,000,  respectively,  for the same  period  in 2008.  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

                  PS 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 transfers 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 (the  "Management
         Agreement")  with PS  pursuant to which PS  operates  the  self-storage
         facilities for a fee equal to 6% of the  facilities'  gross revenue (as
         defined).  For the three  months  ended  June 30,  2009 and  2008,  the
         Partnership  paid PS $167,000 and  $173,000,  respectively,  under this
         Management Agreement.  For the six months ended June 30, 2009 and 2008,
         the Partnership paid PS $334,000 and $341,000, respectively, under this
         Management Agreement.

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

                  A real estate  facility owned by the  Partnership  (the "Azusa
         Property")  is  operated  pursuant  to  a  management  and  performance
         agreement (the  "Performance  Agreement")  with a subsidiary of PS (the
         "PS Sub").  Following the commencement of the Performance  Agreement in
         March 2001, the facility was initially  expanded to include  industrial
         space,  and  this  industrial  space  was  subsequently   converted  to
         self-storage space. These improvements, along with any other subsequent
         improvements or capital expenditures during the term of the Performance
         Agreement,  are entirely  funded by the PS Sub.  During the term of 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 Performance 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 PS in the  market  in which  this  facility  is
         located (the "Guaranteed  Amounts").  The Performance Agreement expires
         on December  31,  2015,  at which time the  Partnership  will  commence
         collecting the actual net operating  income  currently earned by the PS
         Sub from operating the Azusa Property,  and the Guaranteed Amounts will
         no  longer  apply.  The PS Sub  recorded  revenues  of  $1,026,000  and
         $951,000 for the six months ended June 30, 2009 and 2008, respectively,
         and cost of operations totaling $341,000 and $339,000 in the six months
         ended  June 30,  2009  and  2008,  respectively,  with  respect  to the
         operation of the Azusa  property.  Capital  expenditures  for the Azusa
         property  totaled  $4,000 and  $1,000 in the six months  ended June 30,
         2009 and 2008,  respectively.  Average  occupancy of the Azusa Property
         was 89.2% and 81.1% during the six months ended June 30, 2009 and 2008,
         respectively.  The lower average  occupancy during the six months ended
         June 30, 2008 is primarily due to the fill-up of expanded  self-storage
         space which was completed at the Azusa property, and paid for by the PS
         Sub,  during 2006.  Included in the line item  "revenues from affiliate
         under  performance   agreement"  in  the   Partnership's   accompanying
         condensed statements of income, is the Guaranteed Amounts earned by the
         Partnership under the Performance Agreement.

                  The Partnership's  facilities,  along with facilities owned by
         PS and its affiliates,  are managed and marketed jointly by PS in order
         to take  advantage  of scale and other  efficiencies.  Joint  costs are
         allocated on a  methodology  meant to fairly  allocate such costs based
         upon the related  activities.  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 included
         in cost of  operations  on our  accompanying  condensed  statements  of
         income,  amounted to $462,000  and  $501,000 for the three months ended
         June 30, 2009 and 2008, respectively, and $915,000 and $953,000 for the
         six months ended June 30, 2009 and 2008, respectively.

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

                  In addition to the general  partnership  interests outlined in
         Note 4, PS owns 11,671 Limited Partnership Units ("Units"), as to which
         PS has sole voting and dispositive power.

                  At December  31,  2008,  Hughes and members of his family (the
         "Hughes  Family")  owned 6,198 Units.  Hughes owned 5,892 Units,  as to
         which  Hughes  had  sole  voting  and  dispositive  power,   through  a
         wholly-owned corporation and Tamara Hughes Gustavson, an adult daughter
         of Hughes, owned 306 Units as to which Tamara Hughes Gustavson had sole
         voting and  dispositive  power.  On January 1, 2009,  PS exercised  its
         option to acquire the 306 Units held by Tamara  Hughes  Gustavson for a
         cost of  approximately  $136,000.  At June 30, 2009,  Hughes owns 5,892
         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,  PS owns 46% and members of PS
         management and related individuals own approximately 6%.

         Captive Insurance Activities with PS
         ------------------------------------

                  The  Partnership  has a 1.8%  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 PS. The
         Partnership  accounts for its investment in STOR-Re,  which is included
         in other assets in our accompanying  condensed  balance sheets,  on the
         cost method,  and has received no  distributions  during the six months
         ended June 30, 2009 or 2008.

                  STOR-Re  provides  limited  property and  liability  insurance
         coverage to the  Partnership,  PS, 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 PS (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 PS
         ------------------------

                  PS Insurance Company - Hawaii, Ltd.  ("PSICH"),  a corporation
         that  reinsures  policies  against losses to goods stored by tenants in
         the  Partnership's  and PS'  storage  facilities.  PSICH  receives  the

         premiums  and bears the risks  associated  with the  re-insurance.  The
         Partnership  receives a fee (an "Access  Fee") from PSICH in return for
         providing  tenant  listings.  This Access Fee is based on the number of
         spaces the  Partnership  has to rent.  Included in other  income on our
         accompanying  condensed  statements of income for these Access Fees are
         $76,000 and $58,000 for the three  months ended June 30, 2009 and 2008,
         respectively  and  $152,000  and $116,000 for the six months ended June
         30, 2009 and 2008, respectively.

                  A subsidiary of PS sells locks and boxes to the general public
         and tenants to be used in securing their spaces and moving their goods.
         The  subsidiary  of PS receives  the revenues and bears the cost of the
         activities.

6.       COMMITMENTS AND CONTINGENCIES

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

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

                  The  plaintiff  sued PS 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.  Subsequently, PS
         filed a motion for  summary  judgment  seeking to dismiss the matter in
         its  entirety.  On June 22,  2007,  the Court  granted  the PS' summary
         judgment  motion as to the causes of action  relating to the subclasses
         certified and dismissed  those claims.  The only  surviving  claims are
         those  relating  to the named  plaintiff.  The  plaintiff  has filed an
         appeal to the Court's June 22, 2007 summary judgment ruling. On October
         28, 2008, the Court of Appeals sustained the trial court's ruling.  The
         plaintiff  filed a petition  for  review  with the  California  Supreme
         Court, which was granted but further action in this matter was deferred
         pending  consideration  and  disposition  of a related issue in Brinker
         Restaurant  Corp. v. Superior  Court which is currently  pending before
         the California Supreme Court.

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

                  PS  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:  This document  contains  forward-looking
statements within the meaning of the federal  securities laws. All statements in
this document,  other than  statements of historical  fact, are  forward-looking
statements  which  may  be  identified  by  the  use  of  the  words  "expects,"
"believes,"  "anticipates,"  "plans," "would,"  "should," "may," "estimates" and
similar expressions.  These forward-looking statements involve known and unknown
risks and  uncertainties,  which may cause Public Storage  Properties IV, Ltd.'s
(the  "Partnership")  actual results and performance to be materially  different
from those expressed or implied in the forward-looking  statements. As a result,
you should not rely on any  forward-looking  statements in this report, or which
management  may make orally or in writing from time to time, as  predictions  of
future events nor guarantees of future performance.  We caution you not to place
undue reliance on  forward-looking  statements,  which speak only as the date of
this  report  or as of  the  dates  indicated  in  the  statements.  All  of our
forward-looking  statements,  including  those in this report,  are qualified in
their entirely by this statement. We expressly disclaim any obligation to update
publicly or otherwise revise any forward-looking statements, whether as a result
of new  information,  new estimates,  or other factors,  events or circumstances
after  the  date of this  document,  except  where  expressly  required  by law.
Accordingly,   you  should  use  caution  in  relying  on  past  forward-looking
statements to anticipate future results.

         Factors and risks that may impact our future  results  and  performance
include,  but are not limited to, those  described in Item 1A, "Risk Factors" in
the Public Storage  Properties IV, Ltd.  Annual Report on Form 10-K for the year
ended  December  31,  2008 and in our  other  filings  with the  Securities  and
Exchange Commission ("SEC"). These risks include, among others, the following:

         o  general  risks  associated  with the ownership and operation of real
            estate  including  changes  in  demand,   potential   liability  for
            environmental  contamination,  adverse  changes  in  tax,  including
            property tax, real estate and zoning laws and  regulations,  and the
            impact of natural disasters;

         o  risks  associated  with  downturns  in the  local  economies  in the
            markets  in which we  operate,  including  risks  related to current
            economic conditions;

         o  the impact of  competition  from new and existing  self-storage  and
            commercial facilities and other storage alternatives;

         o  the impact of the regulatory environment as well as national, state,
            and local laws and regulations including,  without limitation, those
            governing environmental, tax and tenant insurance matters, and risks
            related to the impact of new laws and regulations;

         o  disruptions  or shutdowns of our automated  processes and systems or
            breaches of our data security; and

         o  economic uncertainty due to the impact of war or terrorism.

         The risks  included  here are not  exhaustive as it is not possible for
management  to predict all  possible  risk factors that may exist or emerge from
time to time. Investors should refer to our future reports and other information
filed from time to time with the SEC for additional information.

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

         Management's Discussion and Analysis of Financial Condition and Results
of Operations  discusses our financial  statements,  which have been prepared in
accordance with United States ("U.S.") generally accepted accounting  principles
("GAAP"). The preparation of our financial statements and related disclosures in

                                       11



conformity with GAAP and our discussion and analysis of our financial  condition
and results of operations requires management to make judgments, assumptions and
estimates that affect the amounts reported in our condensed financial statements
and accompanying  notes. The notes to the Partnership's  June 30, 2009 condensed
financial  statements,  primarily Note 2, summarize the  significant  accounting
policies  and  methods  used  in  the  preparation  of our  condensed  financial
statements and related disclosures.

         Management  believes the following are critical accounting policies the
application  of which  has a  material  impact  on the  Partnership's  financial
presentation. That is, they are both important to the portrayal of our financial
condition  and  results,  and they  require  management  to make  judgments  and
estimates about matters that are inherently uncertain.

         IMPAIRMENT OF REAL ESTATE:  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  includes  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 June 30, 2009.  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  the
Partnership's 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 GAAP, 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 June 30, 2009 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, our expenses could be misstated.

OVERVIEW OF MANAGEMENT'S DISCUSSION AND ANALYSIS OF OPERATIONS
- --------------------------------------------------------------

         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 Public Storage ("PS") provides
several  distinguishing  characteristics  that enable the Partnership to compete
effectively with other owners and operators.

         PS is the largest owner and operator of self-storage  facilities in the
U.S.  All of the PS  facilities  in the U.S.  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 PS as one of
the  dominant  providers  of  self-storage  space  in most  markets  in which PS
operates  and  enables PS 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  competitors  of PS, as well as more
substantial,  well-placed  yellow  page  advertisements  than  can  many  of its
competitors.

                                       12



         The self-storage  industry is not immune to the recessionary  pressures
in the general economic  environment.  Demand for self-storage space in the U.S.
has softened and, as a result, the Partnership is experiencing downward pressure
on occupancy levels, rental rates and revenue growth.

         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 any potential future increases in rental
income to come  primarily  from increases in realized rent rather than increases
in occupancy,  although there can be no assurance that we will  experience  such
increases.

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

         THREE MONTHS ENDED JUNE 30, 2009 AS COMPARED TO THREE MONTHS ENDED JUNE
30, 2008:

         The  Partnership's  net income for the three months ended June 30, 2009
was  $2,275,000,  as  compared  to  $2,206,000  for the  same  period  in  2008,
representing  an  increase of $69,000 or 3.1%.  Property  net  operating  income
(rental income less cost of operations, management fees paid to an affiliate and
depreciation  expense)  decreased  $65,000 or 3.5% from $1,861,000 for the three
months  ended June 30, 2008 to  $1,796,000  for the three  months ended June 30,
2009.

         Rental  income for the three months ended June 30, 2009 was  $2,786,000
as compared to $2,895,000 for the three months ended June 30, 2008, representing
a decrease of $109,000 or 3.8%.  The decrease in rental  income is  attributable
primarily to a 3.3%  decrease in  annualized  realized rent for the three months
ended June 30, 2009 to $15.10 per occupied  square  foot,  as compared to $15.62
per  occupied  square foot for the same period in 2008.  Additionally,  weighted
average occupancy levels at the self-storage  facilities  decreased  slightly to
90.5% for the three  months  ended June 30,  2009,  as compared to 91.2% for the
same period in 2008. These amounts exclude the property operated pursuant to the
management and performance agreement with a subsidiary of PS (the "PS Sub"). See
Note 5 to the  Partnership's  June 30, 2009 condensed  financial  statements for
additional information.

         We believe  that  demand  for  self-storage  space has been  negatively
impacted  by general  economic  conditions,  the slow down in housing  sales and
moving  activity,  as  well  as  increased   competition.   Based  upon  certain
comparative  June  30,  2009  key  operating   metrics  for  the   Partnership's
self-storage  facilities - a 1.5% decline in square foot occupancy from 92.2% at
June 30, 2008 to 90.8% at June 30, 2009, and 6.2% lower in place annual rent per
occupied square foot from $17.82 at June 30, 2008 to $16.71 at June 30, 2009, we
expect that the revenue decline for the  Partnership's  facilities for the three
months  ending  September  30, 2009, as compared to the same period in 2008 will
approximate  8%. The  Partnership's  operating  strategy  will be to continue to
focus on maintaining  occupancy  levels by adjusting  rental rates,  promotional
discounts  and  marketing  activities.  It is  unclear  to us how much the above
mentioned factors will impact our revenues beyond the third quarter of 2009.

         Other income was $176,000 for the three months ended June 30, 2009,  as
compared to $67,000 for the three months ended June 30,  2008,  representing  an
increase of $109,000 or 162.7%. Included in other income are access fees paid by
PS  Insurance  Company -  Hawaii,  Ltd.  ("PSICH"),  a  corporation  owned by PS
(described  more fully in Note 5 to the  Partnership's  June 30, 2009  condensed
financial  statements),  totaling $76,000 and $58,000 for the three months ended
June 30, 2009 and 2008,  respectively.  Included  in other  income for the three
months ended June 30, 2009 is $97,000 in nonrecurring  income in settlement of a
contractual  issue.  Interest income on cash balances for the three months ended
June 30,  2009  declined  as  compared  to the same  period  in 2008.  While the
Partnership had higher average cash balances,  interest rates were significantly
lower in the three  months ended June 30, 2009 as compared to the same period in
2008. The  Partnership  has $1,199,000 in cash on hand at June 30, 2009 invested
primarily in  money-market  funds,  which earn nominal  rates of interest in the
current interest rate environment.

         Revenues from  Affiliates  under the  Performance  Agreement  increased
$24,000  or 7.5% to  $345,000  for the three  months  ended  June 30,  2009 from
$321,000  for  the  three  months  ended  June  30,  2008.  See  Note  5 to  the
Partnership's  June  30,  2009  condensed   financial   statements  for  further
discussion of the nature of these revenues.

                                       13



         Cost of  operations,  including  management  fees paid to an affiliate,
(see Note 5 to the Partnership's June 30, 2009 condensed  financial  statements)
for the three months  ended June 30, 2009 was $880,000  compared to $928,000 for
the three  months  ended June 30,  2008,  representing  a decrease of $48,000 or
5.2%, as reductions  in  advertising  and  promotion,  repairs and  maintenance,
payroll  expenses,  and eviction  costs,  were partially  offset by increases in
property tax, utilities and professional fees expenses.

         Depreciation  expense was  $110,000  and  $106,000 for the three months
ended June 30, 2009 and 2008, respectively, representing an increase of $4,000.

         Administrative  expense was  $42,000  and $43,000 for the three  months
ended June 30, 2009 and 2008, respectively.

         SIX MONTHS ENDED JUNE 30, 2009 AS COMPARED TO SIX MONTHS ENDED JUNE 30,
2008:

         The Partnership's net income for the six months ended June 30, 2009 was
$4,444,000,  as compared to $4,390,000 for the same period in 2008, representing
an increase of $54,000 or 1.2%.  Property net operating  income  (rental  income
less cost of operations,  management fees paid to an affiliate and  depreciation
expense) decreased $80,000 or 2.2% from $3,661,000 for the six months ended June
30, 2008 to $3,581,000 for the six months ended June 30, 2009.

         Rental income for the six months ended June 30, 2009 was  $5,572,000 as
compared to $5,699,000  for the six months ended June 30, 2008,  representing  a
decrease of  $127,000 or 2.2%.  The  decrease in rental  income is  attributable
primarily  to a 2.3%  decrease in  annualized  realized  rent for the six months
ended June 30, 2009 to $15.16 per occupied  square  foot,  as compared to $15.51
per  occupied  square foot for the same period in 2008.  Additionally,  weighted
average occupancy levels at the self-storage  facilities  decreased  slightly to
90.1% for the six months ended June 30, 2009,  as compared to 90.4% for the same
period in 2008.  These  amounts  exclude the property  operated  pursuant to the
management and performance agreement with a subsidiary of PS (the "PS Sub"). See
Note 5 to the  Partnership's  June 30, 2009 condensed  financial  statements for
additional information.

         Other income was  $257,000  for the six months ended June 30, 2009,  as
compared to $165,000  for the six months ended June 30,  2008,  representing  an
decrease of $92,000 or 55.8%%.  Included in other income are access fees paid by
PS  Insurance  Company -  Hawaii,  Ltd.  ("PSICH"),  a  corporation  owned by PS
(described  more fully in Note 5 to the  Partnership's  June 30, 2009  condensed
financial  statements),  totaling $152,000 and $116,000 for the six months ended
June 30,  2009 and 2008,  respectively.  Included  in other  income  for the six
months ended June 30, 2009 is $97,000 in nonrecurring  income in settlement of a
contractual  issue.  Interest  income on cash  balances for the six months ended
June 30,  2009  declined  as  compared  to the same  period  in 2008.  While the
Partnership had higher average cash balances,  interest rates were significantly
lower in the six months  ended June 30,  2009 as  compared to the same period in
2008. The  Partnership  has $1,199,000 in cash on hand at June 30, 2009 invested
primarily in  money-market  funds,  which earn nominal  rates of interest in the
current interest rate environment.

         Revenues from  Affiliates  under the  Performance  Agreement  increased
$40,000 or 6.3% to $675,000 for the six months ended June 30, 2009 from $635,000
for the six months ended June 30, 2008. See Note 5 to the Partnership's June 30,
2009  condensed  financial  statements  for further  discussion of the nature of
these revenues.

         Cost of  operations,  including  management  fees paid to an affiliate,
(see Note 5 to the Partnership's June 30, 2009 condensed  financial  statements)
for the six months ended June 30, 2009 was $1,782,000 compared to $1,836,000 for
the six months ended June 30, 2008,  representing a decrease of $54,000 or 2.9%,
as reductions in repairs and maintenance,  advertising and promotion,  insurance
and  eviction  costs,  were  partially  offset by  increases  in  property  tax,
professional fees and utilities expenses.

         Depreciation expense was $209,000 and $202,000 for the six months ended
June 30, 2009 and 2008, respectively, representing an increase of $7,000.

                                       14



         Administrative  expense was $69,000 and $71,000 in the six months ended
June 30, 2009 and 2008, respectively, representing a decrease of $2,000 or 2.8%.
This decrease is due to lower allocated expenses.

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

         At June 30, 2009, the Partnership had cash of $1,199,000 as compared to
total  liabilities of $603,000.  Cash generated from operations  ($4,601,000 for
the six months  ended June 30,  2009) has been  sufficient  to meet all  current
obligations  of the  Partnership.  Capital  improvements  totaled  $177,000  and
$187,000 in the six months ended June 30, 2009 and 2008,  respectively.  Capital
improvements are budgeted at $414,000 for the year ending December 31, 2009.

         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.  As the capital and credit
markets are currently  constrained  and in flux,  there can be no assurance that
the  Partnership  would be able to access any such borrowings in order to do so,
if such a course of action were otherwise deemed necessary.

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.  During the three months
ended June 30,  2009,  we paid cash  distributions  to the  limited  and general
partners totaling $1,480,000 ($37.00 per unit) and $514,000,  respectively,  and
$1,600,000 ($40.00 per unit) and $555,000,  respectively, for the same period in
2008.  During the six months ended June 30, 2009, we paid cash  distributions to
the limited  and  general  partners  totaling  $3,240,000  ($81.00 per unit) and
$1,124,000,  respectively,  and  $3,160,000  ($79.00  per unit) and  $1,096,000,
respectively,  for the same period in 2008.  Future  distribution  rates will be
adjusted to levels  which are  supported by  operating  cash flow after  capital
improvements and any other necessary obligations.

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

         Public Storage  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  Securities  Exchange Act of 1934,  as
amended, ("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'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 Rules  13a-15(e) and 15d-15(e) of the Exchange Act.
In designing and evaluating the disclosure  controls and procedures,  management
recognized  that any controls and  procedures,  no matter how well  designed and
operated, can provide only reasonable assurance of achieving the desired control
objectives  and  management  necessarily  was  required to apply its judgment in
evaluating the cost-benefit  relationship of possible controls and procedures in
reaching that level of reasonable assurance.

         As of the end of the  fiscal  quarter  covered by this  report,  Public
Storage  carried  out  an  evaluation,   under  the  supervision  and  with  the
participation of the Partnership's management,  including Public Storage's Chief
Executive  Officer and Chief  Financial  Officer,  of the  effectiveness  of the
design and operation of the Partnership's disclosure controls and procedures (as
such term is defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act. Based
on that evaluation, Public Storage's Chief Executive Officer and Chief Financial
Officer concluded that the Partnership's disclosure controls and procedures were
effective.

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