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


1.       DESCRIPTION OF THE BUSINESS

              Public  Storage  Properties  IV, Ltd.,  (the  "Partnership")  is a
         publicly held limited  partnership  formed under the California Uniform
         Limited  Partnership  Act in  December  1977.  The  Partnership  raised
         $20,000,000  in gross  proceeds  by  selling  40,000  units of  limited
         partnership  interest  ("Units")  in  an  interstate  offering,   which
         commenced  in May 1978 and  completed  in  November  1978.  The general
         partners  in  the  Partnership  are  Public  Storage,  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.

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.

              Per unit  data is  based on the  weighted  average  number  of the
         limited partnership units (40,000) outstanding during the period.

         Cash and Cash Equivalents:
         --------------------------

              For financial  statement purposes,  the Partnership  considers all
         highly  liquid  financial   instruments  such  as  short-term  treasury
         securities or investment grade  short-term  commercial paper to be cash
         equivalents.

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

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

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

              In accordance  with this policy,  the Partnership has reflected an
         adjustment  to  unrealized  gains  for  the  change  in  market  price,
         reflecting a decrease in cumulative  unrealized  gain of $7,000 for the
         six months ended June 30, 2006.

         Real Estate Facilities and Evaluation of Asset Impairment:
         ----------------------------------------------------------

              Real estate facilities are recorded at cost. Costs associated with
         the development, construction, renovation and improvement of properties
         are capitalized.  Interest,  property taxes, and other costs associated
         with the  development  incurred  during  the  construction  period  are
         capitalized as building cost.  Expenditures for repairs and maintenance
         are charged to expense as incurred.  Depreciation is computed using the
         straight-line  method over the estimated  useful lives of the buildings
         and improvements,  which are generally between 5 and 25 years.  Certain
         real estate  facilities have been in service longer than 25 years,  and
         accordingly the original  development  cost of such buildings are fully
         depreciated at June 30, 2007.

              We evaluate our real estate for  impairment on a quarterly  basis.
         We first evaluate these assets for indicators of impairment  such as a)
         a  significant  decrease  in the  market  price  of real  estate,  b) a
         significant adverse change in the extent or manner in which real estate
         is being used or in its physical  condition,  c) a significant  adverse
         change in legal  factors or the business  climate that could affect the
         value of the real estate, d) an accumulation of costs  significantly in
         excess of the amount  originally  projected for the  acquisition  of or
         construction of the real estate,  or e) a  current-period  operating or
         cash flow loss combined with a history of operating or cash flow losses
         or  a  projection  or  forecast  that  demonstrates  continuing  losses
         associated with the use of the real estate. When any such indicators of
         impairment are noted,  we compare the carrying value of the real estate
         to the future  estimated  undiscounted  cash flows  attributable to the
         real estate. If the real estate's  recoverable  amount is less than the
         carrying  value of the asset,  then an impairment  charge is booked for
         the excess of carrying value over the real estate's fair value.  Except
         as noted below under  "Accounting for Casualties," our evaluations have
         identified no such impairments at June 30, 2007.

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

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

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

                                       6


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

              During 2005,  we recorded a casualty  gain  totaling  $38,000 as a
         result of physical damage to our facilities  caused by Hurricane Wilma,
         which occurred in the fourth quarter of 2005. This gain represented the
         excess  of the  insurance  proceeds  that we  expected  to  receive  of
         approximately  $41,000 over the aggregate net book values of the assets
         damaged  ($3,000).  In 2006,  we  reevaluated  the damage caused by the
         hurricane  as well as the cost to repair  this  damage and any  related
         insurance  proceeds.  Based  on  this  reevaluation,   we  recorded  an
         additional   casualty  gain  of  $31,000.   This  gain  represents  the
         additional insurance proceeds that we expect to receive.

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

              Deferred revenue  totaling  $320,000 at June 30, 2007 ($313,000 at
         December 31, 2006),  consists of prepaid  rents,  which are  recognized
         when earned.

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

              The Partnership's  policy is to accrue  environmental  assessments
         and/or  remediation costs when it is probable that such efforts will be
         required and the related  costs can be reasonably  estimated.  Although
         there  can be no  assurance,  we are  not  aware  of any  environmental
         contamination at any of our facilities,  which,  individually or in the
         aggregate,  would  be  material  to  our  overall  business,  financial
         condition or results of operations.

         Income Taxes:
         -------------

                  Public Storage Properties IV, Ltd. is treated as a partnership
         for Federal 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 or state income tax expense is
         recorded by the Partnership.

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

              As of August  14,  2007,  there  have  been no  recent  accounting
         pronouncements   and   guidance,   which   were   not   effective   for
         implementation  prior to June 30,  2007,  that  would  have a  material
         impact upon  reporting  the  operations  or  financial  position of the
         Partnership.

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

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

3.       CASH DISTRIBUTIONs

              The  Partnership   Agreement  requires  that  cash  available  for
         distribution  (cash flow from all sources less cash  necessary  for any
         obligations or capital  improvements)  needs to be distributed at least
         quarterly.   For  the  three  months  ended  June  30,  2007,  we  paid
         distributions to the limited and general partners  totaling  $2,960,000
         ($74.00  per unit) and  $1,027,000,  respectively.  For the six  months
         ended June 30, 2007, we paid  distributions  to the limited and general
         partners  totaling   $4,480,000  ($112.00  per  unit)  and  $1,554,000,
         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 transactions have no effect on the results
         of operations or distributions to partners.

5.       RELATED PARTY TRANSACTIONS

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

              The  Partnership  has a Management  Agreement  with 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, 2007 and 2006, the Partnership  paid PS $170,000 and $169,000,
         respectively, under this management agreement. For the six months ended
         June 30, 2007 and 2006,  the  partnership  paid  $338,000 and $335,000,
         respectively.

              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 Public Storage Pickup and
         Delivery, LP ("PSPUD"),  a subsidiary of PS. Following the commencement
         of the  Performance  Agreement in March 2001, the facility was modified
         to include  self-storage and industrial  space,  with the cost of these
         improvements  entirely  funded  by  PSPUD.  The  industrial  space  was
         constructed for use in PSPUD's containerized storage operations.  Under
         the Performance Agreement, the Partnership is guaranteed to receive the
         same net  operating  income  it  received  with  respect  to the  Azusa
         Property prior to the effective  date of the agreement,  with an annual
         increase of the greater of a) 1% or b) the  percentage  increase in net
         operating income achieved at the self-storage  facilities managed by PS
         in the  market in which  this  facility  is  located  (the  "Guaranteed
         Amounts").  Where the net operating income earned by the Azusa Property
         is  less  than  these  Guaranteed   Amounts,   PSPUD   supplements  the
         Partnership's  income.  Where the amount  earned by the Azusa  Property
         exceeds the Guaranteed  Amounts,  the excess is remitted to PSPUD.  The
         costs of all capital  improvements  with respect to the Azusa  Property
         are funded by PSPUD. Included in the line item "Revenues from Affiliate
         under Performance Agreement" on the Partnership's Statements of Income,
         is the  pre-depreciation net operating income with respect to the Azusa
         Property.  The Partnership recorded a total of $308,000 and $297,000 in
         revenue with respect to the Performance  Agreement for the three months
         ended June 30, 2007 and 2006,  respectively,  and $610,000 and $587,000
         for the six months ended June 30, 2007 and 2006, respectively.

              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.  As a

         result,  significant components of cost of operations,  such as payroll
         costs,  advertising  and  promotion,   data  processing  and  insurance
         expenses  are  shared  and  allocated   among  the   properties   using
         methodologies  meant to  fairly  allocate  such  costs  based  upon the
         related  activities.  The total of such expenses,  substantially all of
         which are included in cost of operations in the accompanying  condensed
         statements  of income,  amounted to $438,000 and $390,000 for the three
         months  ended June 30, 2007 and 2006,  respectively,  and  $886,000 and
         $771,000 for the six months ended June 30, 2007 and 2006, respectively.

         Ownership Interest by the General Partners

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

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

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

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

              The  Partnership  has a 1.6% ownership  interest in STOR-Re Mutual
         Insurance  Corporation  ("STOR-Re"),  which  was  formed  in 1994 as an
         association  captive  insurance  company,  and is controlled by PS. The
         Partnership  accounts for its investment in STOR-Re,  which is included
         in other assets, on the cost method.

              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 owns a corporation  that reinsures  policies  against losses to
         goods  stored  by  tenants  in  the   Partnership's  and  PS's  storage
         facilities.  This corporation receives the premiums and bears the risks
         associated with the  re-insurance.  The Partnership  receives an access
         fee from this corporation in return for providing tenant listings. This
         fee is based on number of spaces the Partnership has to rent.  Included
         in other income on our accompanying  condensed statements of income for
         these fees are $27,000 and $28,000 for the three  months ended June 30,
         2007 and 2006, respectively, and $55,000 and $55,000 for the six months
         ended June 30, 2007 and 2006, 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

6.       COMMITMENTS AND CONTINGENCIES

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

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

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

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

              Based upon the uncertainty  inherent in any putative class action,
         PS cannot  presently  determine the potential  damages,  if any, or the
         ultimate  outcome of this  litigation.  On November 3, 2003,  the court
         granted  our  motion  to  strike  the  plaintiff's   nationwide   class
         allegations  and to limit any putative  class to  California  residents
         only.  In August 2005,  PS filed a motion to remove the case to federal
         court,  but the case has been  remanded to the  Superior  Court.  PS is
         vigorously  contesting  the claims  upon  which this  lawsuit is based,
         including class certification efforts.

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

              The plaintiff sued 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 subclass certified and dismissed those
         claims.  They only  surviving  claims are those  relating  to the named
         plaintiff only.

         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: 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 are made pursuant to the  safe-harbor  provisions of
Section 21E of the Securities Exchange Act of 1934, as amended,  and Section 27A
of the  Securities  Act of 1933, as amended.  These  forward-looking  statements
involve  known  and  unknown  risks  and  uncertainties,  which  may  cause  the
Partnership's  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 these  forward-looking  statements as  predictions  of future
events.

         Factors  and risks  that may  impact  future  results  and  performance
include,  but are not limited to, those  described in Item 1A, "Risk Factors" in
the  Partnership's  Annual  Report on Form 10-K for the year ended  December 31,
2006 and in our other filings with the Securities and Exchange Commission. These
risks include the following:  changes in general economic  conditions and in the
markets in which the Partnership operates and the impact of competition from new
and existing storage and commercial  facilities and other storage  alternatives,
which could impact rents and occupancy levels at the  Partnership's  facilities;
the impact of the regulatory  environment as well as national,  state, and local
laws and regulations,  which could increase the Partnership's expense and reduce
the Partnership's cash available for distribution;  and economic uncertainty due
to the impact of war or terrorism could adversely affect our business plan.

         We  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
assume no 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.

OVERVIEW
- --------

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

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

                                       11


CRITICAL ACCOUNTING POLICIES

         IMPAIRMENT OF REAL ESTATE

         On a quarterly  basis, we evaluate our real estate for impairment.  The
evaluation of real estate for impairment requires determining whether indicators
of  impairment  exist,  which is a subjective  process.  When any  indicators of
impairment  are  found,  the  evaluation  then  entails  projections  of  future
operating cash flows, which also involves significant judgment. We identified no
such  impairments  at June 30,  2007.  However,  future  events,  or  facts  and
circumstances that currently exist that we have not yet identified,  could cause
us to conclude in the future that our real  estate is  impaired.  Any  resulting
impairment loss could have a material, adverse impact on our financial condition
and results of operations.

         ESTIMATED USEFUL LIVES OF LONG-LIVED ASSETS

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

         ACCRUALS FOR CONTINGENCIES

         We are exposed to business  and legal  liability  risks with respect to
events  that have  occurred,  but in  accordance  with U.S.  generally  accepted
accounting  principles,  we have  not  accrued  for such  potential  liabilities
because the loss is either not  probable or not  estimable or because we are not
aware of the event.  Future  events and the result of pending  litigation  could
result in such potential  losses  becoming  probable and estimable,  which could
have a  material,  adverse  impact on our  financial  condition  or  results  of
operations. Some of these potential losses, which we are aware of, are described
in Notes 5 and 6 to the Partnership's condensed financial statements.

         ACCRUALS FOR OPERATING EXPENSES

         We accrue for property tax expense and other  operating  expenses based
upon estimates and historical trends and current and anticipated local and state
government  rules  and  regulations.  If these  estimates  and  assumptions  are
incorrect,  the timing of the  recognition  of our expenses  could be incorrect.
Cost of operations,  interest expense,  general and administrative  expense,  as
well as television, yellow page, and other advertising expenditures are expensed
as incurred.

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

THREE MONTHS ENDED JUNE 30, 2007 COMPARED TO THREE MONTHS ENDED JUNE 30, 2006:

         Our net income for the three months ended June 30, 2007 was  $2,145,000
compared to $2,169,000 for the three months ended June 30, 2006, representing an
increase of $24,000 or 1.1%.

         Rental  income for the three months ended June 30, 2007 was  $2,827,000
compared to $2,831,000 for the three months ended June 30, 2006,  representing a
decrease of $4,000 or 0.1%.  Rental income  remained flat as the slight decrease
in weighted  average  occupancy of 90% for the three months ended June 30, 2007,
compared to 91% for the same period in 2006 was mostly  offset by an increase in
annualized  realized rent per square foot to $15.46 per occupied square foot for
the three  months ended June 30,  2007,  compared to $15.29 per occupied  square
foot for the same period in 2006.

         Dividend  income was $8,000 for the three  months  ended June 30, 2006.
During  the  fourth  quarter  of 2006,  we sold all  remaining  shares of Public
Storage stock on the open market.  Accordingly,  the Partnership had no dividend
income for the three months ended June 30, 2007.

                                       12


         Cost of operations  (including  management fees paid to affiliate - see
Note 5 to the condensed  financial  statements)  for the three months ended June
30, 2007 was  $918,000  compared to $893,000 for the three months ended June 30,
2006,  representing  an increase  of $25,000 or 2.8%,  which was  primarily  the
result of  increases  in  advertising  and  promotion  and property tax expense,
partially offset by reductions in payroll expense.

         Depreciation  expense was  $105,000 for the three months ended June 30,
2007  compared to $99,000 for the same period in 2006,  an increase of $6,000 or
6.1%.

SIX MONTHS ENDED JUNE 30, 2007 COMPARED TO SIX MONTHS ENDED JUNE 30, 2006:

         Our net income for the six months  ended June 30,  2007 was  $4,272,000
compared to $4,278,000  for the six months ended June 30, 2006,  representing  a
decrease of $6,000.

         Rental  income for the six months  ended June 30,  2007 was  $5,635,000
compared to $5,597,000 for the six months ended June 30, 2006,  representing  an
increase of $38,000 or 0.7%.  This  increase is  attributable  to an increase in
annualized  realized  rents per square  foot at the  Partnership's  self-storage
facilities.  Weighted average  occupancy  levels at the self-storage  facilities
were 90% and 91% for the six months ended June 30, 2007 and 2006,  respectively.
Annualized  realized rent per square foot for the six months ended June 30, 2007
increased  to $15.42 per occupied  square foot from $15.18 per  occupied  square
foot for the six months ended June 30, 2006.

         Dividend  income for the six months  ended June 30,  2006 was  $16,000.
During the fourth  quarter of 2006, we sold all our  remaining  shares of Public
Storage stock on the open market.  Accordingly,  the Partnership had no dividend
income for the six months ended June 30, 2007.

         Cost of operations  (including  management fees paid to affiliate - see
Note 5 to the condensed financial  statements) for the six months ended June 30,
2007 was  $1,835,000  compared to  $1,774,000  for the six months ended June 30,
2006,  representing  an increase  of $61,000 or 3.4%,  which was  primarily  the
result of increases in advertising and promotion and property tax expense.

         Depreciation  expense was  $209,000  for the six months  ended June 30,
2007 compared to $192,000 for the same period in 2006, an increase of $17,000 or
8.9%.

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

         Cash generated  from  operations  ($4,846,000  for the six months ended
June 30,  2007)  has been  sufficient  to meet all  current  obligations  of the
Partnership.  Capital  improvements  totaled  $142,000  and $203,000 for the six
months ended June 30, 2007 and 2006, respectively.

         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.

         The Partnership Agreement requires that cash available for distribution
(cash flow from all sources less cash  necessary for any  obligations or capital
improvement  needs) be distributed at least quarterly.  We paid distributions to
the limited  and  general  partners  totaling  $2,960,000  ($74.00 per unit) and
$1,027,000,  respectively,  for the three months  ended June 30,  2007.  We paid
distributions to the limited and general partners totaling  $4,480,000  ($112.00
per unit) and $1,554,000,  respectively, for the six months ended June 30, 2007.
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 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 Rule 13a-15(e) of
the Exchange  Act. In  designing  and  evaluating  the  disclosure  controls and
procedures,  management  recognized that any controls and procedures,  no matter
how well  designed  and  operated,  can provide  only  reasonable  assurance  of
achieving the desired control objectives.

         At the end of the period 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.  Based upon that evaluation,
the Chief  Executive  Officer and Chief  Financial  Officer  concluded  that the
Partnership's  disclosure  controls and procedures  were  effective.  During the
second quarter of 2007, there were no significant  changes in the  Partnership's
internal controls over financial reporting that have materially affected, or are
reasonably likely to materially affect, the Partnership's  internal control over
financial reporting.
