                     NOTES TO CONDENSED FINANCIAL STATEMENTS

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,  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.

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.

     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.

                                       5



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



          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 with remaining  maturities of
     three months or less at the date of acquisition to be cash equivalents.

     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 March 31, 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  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,  then an impairment  charge is booked for the
     excess of carrying value over the real estate's fair value. Our evaluations
     have identified no such impairments at March 31, 2009.

          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 Casualty Losses:
     -------------------------------

          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 contingent proceeds in accordance with
     Statement  of  Financial  Accounting  Standards  No. 5 ("SFAS 5"),  and not
     recorded until the uncertainties are satisfied.

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

          Deferred  revenue  totaling  $303,000 at March 31, 2009  ($297,000  at
     December 31,  2008),  consists of prepaid  rents,  which are  recognized as
     rental income when earned.

                                   (UNAUDITED)



     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  May  14,   2009,   there   have  been  no  recent   accounting
     pronouncements  and guidance,  which were not effective for  implementation
     prior to March 31, 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  March 31,  2009,  we paid cash
     distributions  to the  limited  and general  partners  totaling  $1,760,000
     ($44.00 per unit) and $610,000, respectively. During the three months ended
     March 31,  2008,  we paid cash  distributions  to the  limited  and general
     partners totaling $1,560,000 ($39.00 per unit) and $541,000,  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

          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  March  31,  2009  and  2008,  the
     Partnership  paid  PS  $167,000  and  $168,000,  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 $497,000 and $484,000 in the three months ended March
     31,  2009 and  2008,  respectively,  and  incurred  operating  expenses  of
     $181,000 for each of the three month periods ended March 31, 2009 and 2008,
     respectively,  with respect to the operation of the Azusa Property. Capital
     expenditures  for the Azusa  Property  totaled  $4,000 and $10,000,  in the
     three months ended March 31, 2009 and 2008, respectively. Average occupancy
     of the Azusa  Property  was 88.7% and 76.5%  during the three  months ended
     March 31, 2009 and 2008,  respectively.  The lower average occupancy during
     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 $453,000 and $452,000 for the
     three months ended March 31, 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 March
     31, 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 three months ended
     March 31, 2009.

          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.  ("PSIC"),  a  corporation  that
     reinsures  policies  against  losses  to goods  stored  by  tenants  in the
     Partnership's  and PS' storage  facilities.  PSIC receives the premiums and
     bears the risks associated with the re-insurance.  The Partnership receives
     a fee (an "Access Fee") from PSIC 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 $85,000 for the three  months
     ended March 31, 2009 and 2008, respectively.

          A  subsidiary  of PS 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 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 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  Quarterly  Report  on  Form  10-Q
     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, 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 the current  global
          fiscal crisis;

     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;

     o    disruptions or shutdowns of our automated processes and systems; 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 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  March 31, 2009 condensed  financial

                                       11



     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 March 31, 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  March 31,  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.

          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.

                                       12



          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  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.

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

          THREE  MONTHS  ENDED MARCH 31, 2009 AS COMPARED TO THREE  MONTHS ENDED
          MARCH 31, 2008:

          The Partnership's net income for the three months ended March 31, 2009
     was  $2,169,000,  as  compared to  $2,184,000  for the same period in 2008,
     representing a decrease of $15,000 or 0.7%.  Property net operating  income
     (rental  income  less  cost  of  operations,  management  fees  paid  to an
     affiliate  and  depreciation   expense)  decreased  $15,000  or  0.8%  from
     $1,800,000  for the three months ended March 31, 2008 to $1,785,000 for the
     three months ended March 31, 2009.

          Rental income for the three months ended March 31, 2009 was $2,786,000
     as compared  to  $2,804,000  for the three  months  ended  March 31,  2008,
     representing  a decrease of $18,000 or 0.6%.  The decrease in rental income
     is attributable primarily to a decrease in annualized realized rent for the
     three months ended March 31, 2009 to $15.22 per  occupied  square foot,  as
     compared  to $15.41 per  occupied  square foot for the same period in 2008,
     offset by a slight increase in the weighted average occupancy levels at the
     self-storage  facilities  from 89.5% for the three  months  ended March 31,
     2008 to 89.6%  for the same  period  in 2009.  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  March
     31, 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.  It is unclear to us how
     much we have been negatively impacted by these factors,  and how much these
     factors may impact us going forward.

          Other income was $81,000 for the three months ended March 31, 2009, as
     compared to $98,000 for the three months ended March 31, 2008, representing
     a decrease of $17,000 or 17.3%.  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  March 31, 2009
     condensed financial statements), totaling $76,000 and $85,000 for the three
     months  ended  March 31,  2009 and 2008,  respectively.  Included  in other
     income for the three months  ended March 31, 2008 are access fees  totaling
     $27,000,  which represent changes in accounting  estimates recorded in 2008
     with  respect  to  fees  that  were  earned  in  2007.  Additional  similar
     adjustments  were made in later periods in 2008 as the 2007 fees  continued
     to be evaluated.  Amounts recorded in the three months ended March 31, 2009
     reflect  the  current  ongoing  level of access  fees  based  upon  current
     activity levels.  Other income for the three months ended March 31, 2009 as
     compared to the same period in 2008  reflects a decline in interest  income
     on cash balances.  While the  Partnership had higher average cash balances,
     interest rates were significantly lower in the three months ended March 31,
     2009 as compared to the same period in 2008. The Partnership has $1,187,000
     in cash on hand at March 31, 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
     $16,000 or 5.1% to $330,000  for the three months ended March 31, 2009 from
     $314,000  for the three  months  ended  March 31,  2008.  See Note 5 to the
     Partnership's  March 31, 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  March  31,  2009  condensed  financial
     statements) for the three months ended March 31, 2009 was $902,000 compared
     to $908,000  for the three  months  ended March 31,  2008,  representing  a
     decrease of $6,000,  as reductions in repairs and maintenance,  payroll and
     eviction  costs,  were  mostly  offset  by  increases  in  advertising  and
     promotion, property tax and utilities expenses.

                                       13



          Depreciation  expense was  $99,000  and  $96,000 for the three  months
     ended March 31, 2009 and 2008,  respectively,  representing  an increase of
     $3,000.

          Administrative  expense was  $27,000  and $28,000 in the three  months
     ended March 31,  2009 and 2008,  respectively,  representing  a decrease of
     $1,000 or 3.6%. This decrease is due to lower allocated expenses.

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

          Cash generated from operations  ($2,441,000 for the three months ended
     March 31, 2009) has been sufficient to meet all current  obligations of the
     Partnership.  Capital improvements totaled $23,000 and $12,000 in the three
     months ended March 31, 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  March 31,  2009,  we paid cash
     distributions  to the  limited  and general  partners  totaling  $1,760,000
     ($44.00 per unit) and $610,000, respectively. During the three months ended
     March 31,  2008,  we paid cash  distributions  to the  limited  and general
     partners totaling $1,560,000 ($39.00 per unit) and $541,000,  respectively.
     Future distribution rates will be adjusted to levels which are supported by
     operating  cash flow after  capital  improvements  and any other  necessary
     obligations.

                                       14




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.

4.   The  registrant's  other  certifying  officer  and  I are  responsible  for
     establishing and maintaining disclosure controls and procedures (as defined
     in Exchange Act Rules  13a-15(e) and  15d-15(e))  for the registrant and we
     have:

     a)   designed  such  disclosure  controls  and  procedures,  or caused such
          disclosure   controls  and   procedures  to  be  designed   under  our
          supervision,  to ensure  that  material  information  relating  to the
          registrant,  including its consolidated subsidiaries, is made known to
          us by others within those entities,  particularly during the period in
          which this report is being prepared;

     b)   [paragraph omitted pursuant to SEC Release Nos. 33-8238 and 34-47986]

     c)   evaluated the  effectiveness of the registrant's  disclosure  controls

          of the period covered by this report based on such evaluation; and

     d)   disclosed  in this  report  any  change in the  registrant's  internal
          control over financial  reporting that occurred the registrant's  most
          recent fiscal quarter (the  registrant's  fourth fiscal quarter in the
          case  of  an  annual  report)  that  has  materially  affected,  or is
          reasonably  likely to materially  affect,  the  registrant's  internal
          control over financial reporting; and

5.   The registrant's  other certifying  officer and I have disclosed,  based on
     our most recent evaluation of internal control over financial reporting, to
     the registrant's  auditors and the audit committee of registrant's board of
     directors (or person performing the equivalent functions):

     a)   all significant  deficiencies and material weaknesses in the design or
          operation  of internal  control  over  financial  reporting  which are
          reasonably  likely to  adversely  affect the  registrant's  ability to
          record, process, summarize and report financial information; and

     b)   any fraud, whether or not material,  that involves management or other
          employees who have a  significant  role in the  registrant's  internal
          control over financial reporting.
