                       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.

                     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 gains of $8,000 for the
         nine months ended September 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 September 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 September 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

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


         insurance   proceeds  that  are  subject  to  uncertainties,   such  as
         interpretation of deductible  provisions of the governing agreements or
         the  estimation  of costs of  restoration,  are treated as a contingent
         proceeds in accordance with Statement of Financial Accounting Standards
         No.  5  ("SFAS  5"),  and not  recorded  until  the  uncertainties  are
         satisfied.

                  During 2005, we recorded a casualty gain totaling $38,000 as a
         result of physical damage to our facilities  caused by Hurricane Wilma,
         which occurred in the fourth quarter of 2005. This gain 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  $271,000  at  September  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 November 13, 2007, there have been no recent  accounting
         pronouncements   and   guidance,   which   were   not   effective   for
         implementation  prior to September 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  September  30,  2007,  we paid
         distributions to the limited and general partners  totaling  $1,880,000
         ($47.00 per unit) and $652,000, respectively. For the nine months ended

         September  30, 2007, we paid  distributions  to the limited and general
         partners  totaling   $6,360,000  ($159.00  per  unit)  and  $2,206,000,
         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
         September  30, 2007 and 2006,  the  Partnership  paid PS  $171,000  and
         $174,000,  respectively,  under this management agreement.  For each of
         the nine months ended September 30, 2007 and 2006, the partnership paid
         $509,000.

                  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 nine 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 $354,000 and $340,000 in
         revenue with respect to the Performance  Agreement for the three months
         ended  September  30, 2007 and 2006,  respectively,  and  $964,000  and
         $927,000  for the nine  months  ended  September  30,  2007  and  2006,
         respectively.

                                   (UNAUDITED)


                  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 $327,000 and $370,000 for the three
         months ended September 30, 2007 and 2006, respectively,  and $1,213,000
         and $1,141,000  for the nine months ended  September 30, 2007 and 2006,
         respectively.

         Ownership Interest by the General Partners

                  In addition to the general  partnership  interests outlined in
         Note 4, 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 $28,000 and $27,000 for the three months ended September
         30, 2007 and 2006,  respectively,  and $83,000 and $82,000 for the nine
         months ended September 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
         bears the cost of the activities.

6.       COMMITMENTS AND CONTINGENCIES

         Legal Proceedings:

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

                  The  plaintiff  in this case filed a suit against 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.

                  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  PS'  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 subclasses  certified
         and  dismissed  those  claims.  The only  surviving  claims  are  those
         relating to the named plaintiff only. The plaintiff has filed an appeal
         to the Court's June 22, 2007 summary judgment ruling.

         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.

CRITICAL ACCOUNTING POLICIES

         IMPAIRMENT OF REAL ESTATE

         On a quarterly  basis, we evaluate our real estate for impairment.  The
evaluation of real estate for impairment requires determining whether indicators
of  impairment  exist,  which is a subjective  process.  When any  indicators of
impairment  are  found,  the  evaluation  then  entails  projections  of  future
operating cash flows, which also involves significant judgment. We identified no
such  impairments at September 30, 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 SEPTEMBER 30, 2007 COMPARED TO THREE MONTHS ENDED SEPTEMBER
30, 2006:

         Our net  income  for the three  months  ended  September  30,  2007 was
$2,252,000 compared to $2,306,000 for the three months ended September 30, 2006,
representing a decrease of $54,000 or 2.3%.

         Rental  income  for the  three  months  ended  September  30,  2007 was
$2,858,000 compared to $2,905,000 for the three months ended September 30, 2006,
representing a decrease of $47,000 or 1.6%. Rental income increased slightly due
to an  increase  in  annualized  realized  rent per  square  foot to $15.88  per
occupied square foot for the three months ended September 30, 2007,  compared to
$15.82 per  occupied  square foot for the same period in 2006,  which was mostly
offset by a decrease in weighted  average  occupancy of 88% for the three months
ended September 30, 2007, compared to 90% for the same period in 2006.

         Dividend  income was $10,000 for the three months ended  September  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 September 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
September 30, 2007 was $896,000  compared to $892,000 for the three months ended
September  30,  2006,  representing  a slight  increase  of  $4,000,  which  was
primarily the result of increases in advertising  and promotion and property tax
expense, partially offset by reductions in repairs and maintenance expense.

         Depreciation  expense was $106,000 for the three months ended September
30, 2007 compared to $96,000 for the same period in 2006, an increase of $10,000
or 10.4% due to depreciation of additional capital expenditures.

NINE MONTHS ENDED SEPTEMBER 30, 2007 COMPARED TO NINE MONTHS ENDED SEPTEMBER 30,
2006:

         Our net  income  for the  nine  months  ended  September  30,  2007 was
$6,524,000  compared to $6,584,000 for the nine months ended September 30, 2006,
representing a decrease of $60,000 or 1%.

         Rental  income  for the  nine  months  ended  September  30,  2007  was
$8,493,000  compared to $8,502,000 for the nine months ended September 30, 2006,
representing a decrease of $9,000.  Rental income  remained flat as the decrease
in weighted  average  occupancy of 89% for the nine months ended  September  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 $15.57 per  occupied
square foot for the nine months ended September 30, 2007, compared to $15.39 per
occupied square foot for the same period in 2006.

         Dividend  income  for the nine  months  ended  September  30,  2006 was
$26,000.  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 nine months ended September 30, 2007.

         Cost of operations  (including  management fees paid to affiliate - see
Note  5 to the  condensed  financial  statements)  for  the  nine  months  ended
September 30, 2007 was  $2,731,000  compared to  $2,666,000  for the nine months
ended September 30, 2006, representing an increase of $65,000 or 2.4%, which was
primarily the result of increases in advertising  and promotion and property tax
expense offset by a decrease in repair and maintenance expense.

         Depreciation  expense was $315,000 for the nine months ended  September
30,  2007  compared  to  $288,000  for the same  period in 2006,  an increase of
$27,000 or 9.4%.

LIQUIDITY AND CAPITAL RESOURCES

         Cash generated from  operations  ($7,232,000  for the nine months ended
September 30, 2007) has been  sufficient to meet all current  obligations of the
Partnership.  Capital  improvements  totaled  $202,000 and $357,000 for the nine
months ended September 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  $1,888,000  ($47.00 per unit) and
$652,000,  respectively,  for the three months ended September 30, 2007. We paid
distributions to the limited and general partners totaling  $6,360,000  ($159.00
per unit) and $2,206,000,  respectively, for the nine months ended September 30,
2007.  During 2007, we have paid more in  distributions  than what was generated
from operating  activities  less capital  expenditures.  This was done to reduce
excess  cash  reserves.  Future  distribution  rates will be adjusted to levels,
which are supported by operating  cash flow after capital  improvements  and any
other necessary  obligations.  As a result, we expect future distributions to be
less than the amounts paid during 2007.

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
third 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.
