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
     footnote  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, 2007, 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.  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 March 31, 2008.

         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.
     Our evaluations have identified no such impairments at March 31, 2008.

         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 a 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  $325,000 at March 31, 2008 and December 31,
     2007, consists of prepaid rents, which are recognized 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  or state  income tax  expense is  recorded  by the
     Partnership.

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

         As of May 15, 2008, there have been no recent accounting pronouncements
     and guidance,  which were not effective for  implementation  prior to March
     31, 2008,  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, 2008, we paid distributions to the limited
     and general partners  totaling  $1,560,000  ($39.00 per unit) and $541,000,
     respectively.  During  the  three  months  ended  March 31,  2007,  we paid
     distributions  to the  limited  and general  partners  totaling  $1,520,000
     ($38.00 per unit) and $527,000, 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 each of the three month periods
     ended March 31, 2008 and 2007, the Partnership paid PS $168,000, 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  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 $314,000 and $302,000 in revenue with
     respect to the  Performance  Agreement for the three months ended March 31,
     2008 and 2007, 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  $366,000  and
     $448,000 for the three months ended March 31, 2008 and 2007, 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.

                                   (UNAUDITED)


         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  1.7%  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  accompanying  condensed  balance  sheets,  on the cost
     method,  and has  received no  distributions  during the three months ended
     March 31, 2008.

         STOR-Re provides limited property and liability  insurance  coverage to
     the  Partnership,  PS, and affiliates for losses  occurring before April 1,
     2004.  STOR-Re was succeeded  with respect to these  activities  for losses
     occurring  after  March  31,  2004  by a  wholly  owned  subsidiary  of  PS
     (collectively,  this  entity and STOR-Re  are  referred to as the  "Captive
     Entities").  Liabilities for losses and loss adjustment expenses include an
     amount  determined  from loss reports and  individual  cases and an amount,
     based on  recommendations  from an outside  actuary that is a member of the
     American Academy of Actuaries,  using a frequency and severity method,  for
     losses  incurred but not  reported.  Determining  the  liability for unpaid
     losses and loss  adjustment  expense is based upon  estimates  and while we
     believe that the amount is adequate,  the ultimate loss may be in excess of
     or less than the amounts  provided.  The methods for making such  estimates
     and for establishing the resulting liability are reviewed quarterly.

     Other Activities with PS
     ------------------------

         PS owns a corporation  that reinsures  policies against losses to goods
     stored by tenants in the  Partnership's  and PS' 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 the number of
     spaces  the  Partnership  has to  rent.  Included  in other  income  on our
     accompanying  statements  of income for these fees are  $58,000 and $28,000
     for the three months ended March 31, 2008 and 2007, 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,

                                   (UNAUDITED)


         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.  An
     appeal to the Court's  June 22, 2007 order  granting  PS' summary  judgment
     motion is currently pending.

     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,  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"
     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;

     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 current
     reports on Form 8-K and other  information filed from time to time with the
     SEC for additional information.

     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  ("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

                                       11


     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.

         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 rather than
     increases in occupancy, although there can be no assurance.

     Critical Accounting Policies
     ----------------------------

         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 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 March  31,  2008.  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  March 31,  2008
     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. Cost of operations, general
     and administrative  expense, as well as television,  yellow page, and other
     advertising expenditures are expensed as incurred.

     Results of Operations
     ---------------------

         Three months ended March 31, 2008  compared to three months ended March
     31, 2007:

         The  Partnership's net income for the three months ended March 31, 2008
     was $2,184,000  compared to $2,127,000 for the three months ended March 31,
     2007, representing an increase of $57,000 or 2.7%.

                                       12




         Rental income for the three months ended March 31, 2008 was  $2,804,000
     compared  to  $2,808,000  for  the  three  months  ended  March  31,  2007,
     representing  a  decrease  of  $4,000.  The  decrease  in rental  income is
     attributable  primarily to a slight decrease in weighted average  occupancy
     levels at the  self-storage  facilities  from 90% in the three months ended
     March 31,  2007 to 89% for the three  months  ended  March 31,  2008.  This
     decrease was mostly offset by an increase in the  annualized  realized rent
     per square foot to $15.41 per  occupied  square  foot for the three  months
     ended March 31, 2008,  compared to $15.38 per occupied  square foot for the
     same period in 2007. These amounts exclude the property  operated  pursuant
     to the management and performance  agreement with Public Storage Pickup and
     Delivery, LP ("PSPUD"), a subsidiary of PS. See Note 5 to the Partnership's
     March 31, 2008 condensed financial statements for additional information.

         Revenues from  Affiliates  under the  Performance  Agreement  increased
     $12,000 or 4% to  $314,000  in the three  months  ended March 31, 2008 from
     $302,000 for the same period in 2007. See Note 5 to the Partnership's March
     31, 2008  condensed  financial  statements  for further  discussion  of the
     nature of these revenues.

         Cost of operations  (including  management fees paid to affiliate - see
     Note 5 to the Partnership's March 31, 2008 condensed financial  statements)
     for the three months ended March 31, 2008 was $908,000 compared to $917,000
     for the three  months  ended  March 31,  2007,  representing  a decrease of
     $9,000,  which was  primarily  the result of decreases in  advertising  and
     promotion and payroll expenses, partially offset by an increase in property
     tax expense.

         Depreciation  expense was $96,000 for the three  months ended March 31,
     2008 compared to $104,000 for the same period in 2007, a decrease of $8,000
     or 7.7%.

     Liquidity and Capital Resources
     -------------------------------

         Cash generated from  operations  ($2,411,000 for the three months ended
     March 31, 2008) has been sufficient to meet all current  obligations of the
     Partnership. Capital improvements totaled $12,000 and $29,000 for the three
     months ended March 31, 2008 and 2007, 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.

     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.  We paid
     distributions  to the  limited  and general  partners  totaling  $1,560,000
     ($39.00 per unit) and  $541,000,  respectively,  for the three months ended
     March 31,  2008.  During the three  months  ended March 31,  2007,  we paid
     distributions   totaling   $1,520,000   ($38.00  per  unit)  and  $527,000,
     respectively.  Future  distribution rates may be adjusted to levels,  which
     are  supported by operating  cash flow after capital  improvements  and any
     other necessary obligations.

                                       13




     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.

                                       14



PART II. OTHER INFORMATION

     Item 1. Legal Proceedings
     -------------------------

         The information set forth under the heading "Legal Proceedings" in Note
     6 to our March 31, 2008 condensed financial statements in this Form 10-Q is
     incorporated by reference in this Item 1.

     Item 1A. Risk Factors
     ---------------------

         In addition to the other  information in this Quarterly  Report on Form
     10-Q, you should  consider the risks described below that we believe may be
     material to investors in evaluating the Partnership.  This section contains
     forward-looking statements, and in considering these statements, you should
     refer  to  the  qualifications  and  limitations  on  our   forward-looking
     statements  that  are  described  in  Forward  Looking  Statements  at  the
     beginning  of Item 2.  Management's  Discussion  and  Analysis of Financial
     Condition and Results of Operations.

         The General Partners control the Partnership as a group.
         --------------------------------------------------------

         Public Storage is general partner and beneficially  owns  approximately
     29.2% of our outstanding limited  partnership units. In addition,  B. Wayne
     Hughes, General Partner of the Partnership,  and Chairman of PS and members
     of his family beneficially own 33.7% of the Limited Partnership units. As a
     result,  the General Partners,  as a group,  control matters submitted to a
     vote of our unitholders,  including amending our organizational  documents,
     dissolving the Partnership and approving other such transactions.

         Since our business consists  primarily of operating real estate, we are
         -----------------------------------------------------------------------
     subject to real estate operating risks.
     ---------------------------------------

         The value of our  investments  may be reduced by general  risks of real
     estate ownership. Since we derive substantially all of our income from real
     estate  operations,  we are  subject to the  general  risks of owning  real
     estate-related assets, including:

         o lack of demand for rental spaces or units in a locale;

         o changes in general economic or local conditions;

         o natural disasters, such as earthquakes;

         o potential terrorist attacks;

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

         o the impact of environmental protection laws;

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

         o increases in insurance  premiums,  property tax assessments and other
           operating and maintenance expenses;

         o adverse changes in tax, real estate and zoning laws and  regulations;
           and

         o tenant and employment-related claims.

                                       15



         There is significant competition among self-storage facilities and from
     other  storage  alternatives.   All  of  our  properties  are  self-storage
     facilities,  which generated substantially all of our revenue for the three
     month  period ended March 31, 2008.  Local  market  conditions  will play a
     significant  part in how  competition  will affect us.  Competition  in the
     market  areas  in which  many of our  properties  are  located  from  other
     self-storage  facilities and other storage  alternatives is significant and
     has affected the occupancy levels,  rental rates and operating  expenses of
     our  properties.  Any increase in  availability  of funds for investment in
     real estate may accelerate competition. Further development of self-storage
     facilities  may  intensify  competition  among  operators  of  self-storage
     facilities in the market areas in which we operate.

         We may incur  significant  environmental  costs and liabilities.  As an
     owner and operator of real  properties,  under various  federal,  state and
     local  environmental  laws,  we are  required  to clean up  spills or other
     releases  of  hazardous  or toxic  substances  on or from  our  properties.
     Certain  environmental  laws impose liability whether or not the owner knew
     of,  or was  responsible  for,  the  presence  of the  hazardous  or  toxic
     substances. In some cases, liability may not be limited to the value of the
     property.  The  presence  of these  substances,  or the failure to properly
     remediate  any  resulting  contamination,  whether  from  environmental  or
     microbial  issues,  also may  adversely  affect the  owner's or  operator's
     ability  to sell,  lease or operate  its  property  or to borrow  using its
     property as collateral.

         We  have  conducted  preliminary   environmental   assessments  on  the
     Partnership's  properties to evaluate the  environmental  condition of, and
     potential environmental liabilities associated with, our properties.  These
     assessments   generally   consist  of  an  investigation  of  environmental
     conditions at the property (not including  soil or groundwater  sampling or
     analysis),  as well as a review of available information regarding the site
     and publicly  available  data  regarding  conditions  at other sites in the
     vicinity.  In connection  with these property  assessments,  we have become
     aware that prior operations or activities at some facilities or from nearby
     locations  have  or may  have  resulted  in  contamination  to the  soil or
     groundwater at these facilities. In this regard, some of our facilities are
     or may be the  subject of federal or state  environment  investigations  or
     remedial  actions.  Although we cannot provide any assurance,  based on the
     preliminary environmental  assessments,  we believe we have funds available
     to cover  any  liability  from  environmental  contamination  or  potential
     contamination  and we are not aware of any  environmental  contamination of
     our facilities  material to our overall  business,  financial  condition or
     results of operation.

         There has been an increasing  number of claims and  litigation  against
     owners and managers of rental properties relating to moisture infiltration,
     which  can  result  in mold or other  property  damage.  When we  receive a
     complaint concerning moisture  infiltration,  condensation or mold problems
     and/or  become  aware that an air  quality  concern  exists,  we  implement
     corrective  measures in accordance  with  guidelines  and protocols we have
     developed  with  the  assistance  of  outside  experts.  We  seek  to  work
     proactively  with  our  tenants  to  resolve   moisture   infiltration  and
     mold-related  issues,  subject to our contractual  limitations on liability
     for such claims.  However,  we can provide no assurance that material legal
     claims relating to moisture  infiltration  and the presence of, or exposure
     to, mold will not arise in the future.

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

         We must comply with the Americans  with  Disabilities  Act and fire and
     safety  regulations,  which can require significant  expenditures.  All our
     properties  must comply with the Americans with  Disabilities  Act and with
     related   regulations  (the  "ADA").   The  ADA  has  separate   compliance
     requirements for "public  accommodations" and "commercial  facilities," but
     generally  requires  that  buildings  be made  accessible  to persons  with
     disabilities.  Various state laws impose similar requirements. A failure to
     comply  with the ADA or  similar  state  laws  could  result in  government
     imposed fines on us and the award of damages to individuals affected by the
     failure.  In addition,  we must operate our  properties in compliance  with
     numerous local fire and safety regulations,  building codes, and other land
     use regulations. Compliance with these requirements can require us to spend
     substantial  amounts of money, which would reduce cash otherwise  available
     for distribution to shareholders. Failure to comply with these requirements
     could also affect the marketability of our real estate facilities.

                                       16



         We incur liability from tenant and employment-related claims. From time
     to time we must  resolve  tenant  claims and  employment-related  claims by
     corporate level and field personnel.

         Public   Storage's   acquisition   of  Shurgard   or  other   potential
         -----------------------------------------------------------------------
     acquisitions  or development  of properties may subject the  Partnership to
     ---------------------------------------------------------------------------
     additional risks.
     -----------------

         In August 2006,  Public Storage  completed the  acquisition of Shurgard
     Storage Centers, Inc. ("Shurgard"), a publicly held REIT that had interests
     in approximately 646 self-storage  facilities  located in the United States
     ("U.S.") and Europe and acquires and develops other real estate  facilities
     as  part  of its  ongoing  operations.  Such  acquisitions,  including  the
     Shurgard merger, do not change the financial  interests of the Partnership.
     However,  because the self-storage facilities of the Partnership and Public
     Storage are managed by Public  Storage,  together  with the newly  acquired
     self-storage facilities, individual Partnership properties may experience a
     decrease in move-ins,  reductions to rental rates, increases to promotional
     discounts,  or other negative  impacts to revenues in the short and/or long
     term due to the  competitive  impact of Public  Storage  management  of the
     newly acquired  facilities,  particularly  with respect to those facilities
     that are close to the Partnership's facilities.

         Some  of  our  revenues   involve   businesses   that  are  subject  to
         -----------------------------------------------------------------------
     governmental  regulation which could reduce our  profitability or limit our
     ---------------------------------------------------------------------------
     growth.
     -------

         We receive  revenues  related to the offering of insurance  products to
     our tenants.  These products are offered  through an affiliate of PS, which
     holds Limited Lines Self Storage  Insurance Agent licenses from a number of
     individual  state  Departments  of  Insurance  and  are  subject  to  state
     governmental   regulation   and   supervision.   This  state   governmental
     supervision   could  reduce  our  profitability  or  limit  our  growth  by
     increasing the costs of regulatory compliance,  limiting or restricting the
     products or services we provide or the methods by which we provide products
     and services, or subjecting our businesses to the possibility of regulatory
     actions or proceedings. The continued ability of this affiliate to maintain
     these  Limited  Lines  Self  Storage   Insurance   Agent  licenses  in  the
     jurisdictions  in which it is licensed  depends on its compliance  with the
     rules  and  regulations  promulgated  from  time to time by the  regulatory
     authorities in each of these  jurisdictions.  Furthermore,  state insurance
     departments conduct periodic examinations, audits and investigations of the
     affairs of insurance agents.

         In all  jurisdictions,  the applicable laws and regulations are subject
     to amendment or interpretation by regulatory authorities.  Generally,  such
     authorities are vested with relatively broad discretion to grant, renew and
     revoke  licenses and approvals and to implement  regulations.  Accordingly,
     this affiliate may be precluded or  temporarily  suspended from carrying on
     some or all of these  activities or otherwise fined or penalized in a given
     jurisdiction.  No assurances  can be given that our businesses can continue
     to be conducted in any given  jurisdiction  as it has been conducted in the
     past.  For the year  ended  December  31,  2007,  revenues  from our tenant
     reinsurance  business  represented  approximately 1.5% of our 2007 revenues
     and 1.8% of revenues for the quarter ended March 31, 2008.

         Terrorist  attacks and the possibility of wider armed conflict may have
         -----------------------------------------------------------------------
     an adverse impact on our business and operating  results and could decrease
     ---------------------------------------------------------------------------
     the value of our assets.
     ------------------------

         Terrorist attacks and other acts of violence or war, such as those that
     took place on September 11, 2001,  could have a material  adverse impact on
     our business and operating  results.  There can be no assurance  that there
     will not be further terrorist attacks against the U.S. or its businesses or
     interests.  Attacks or armed  conflicts that directly impact one or more of
     our  properties  could  significantly  affect our ability to operate  those
     properties and thereby impair our operating  results.  Further,  we may not
     have  insurance  coverage  for losses  caused by a terrorist  attack.  Such
     insurance  may not be  available,  or if it is  available  and we decide to
     obtain  such  terrorist  coverage,  the  cost  for  the  insurance  may  be
     significant in relationship to the risk overall.  In addition,  the adverse
     effects that such violent acts and threats of future  attacks could have on
     the U.S.  economy could  similarly  have a material  adverse  effect on our
     business and results of operations.  Finally,  further terrorist acts could
     cause the U.S. to enter into a wider armed  conflict,  which could  further
     impact our business and operating results.

         Developments in California may have an adverse impact on our business
         -----------------------------------------------------------------------
     and operating results and could decrease the value of our assets.
     -----------------------------------------------------------------

         Twelve of the  Partnership's  properties  are  located  in  California.
     California  is  facing  budgetary  problems.  Action  that  may be taken in
     response  to these  problems,  such as an  increase  in  property  taxes on
     commercial  properties,  could adversely impact our business and results of
     operations.  In addition,  the Partnership  could be adversely  impacted by
     efforts to reenact legislation mandating medical insurance for employees of
     California businesses and members of their families.

         Increases  in  interest  rates may  adversely  affect  the price of our
         -----------------------------------------------------------------------
     partnership units.
     ------------------

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

         We have become increasingly  dependent upon automated processes and the
         -----------------------------------------------------------------------
     Internet and are faced with system security risks.
     --------------------------------------------------

         We have become  increasingly  centralized  and dependent upon automated
     information  technology  processes.  As a  result,  we  could  be  severely
     impacted  by a  catastrophic  occurrence,  such as a natural  disaster or a
     terrorist  attack.  In addition,  a portion of our business  operations are
     conducted  over the  Internet,  increasing  the risk of viruses  that could
     cause system failures and disruptions of operations.  Experienced  computer
     programmers   may  be  able  to   penetrate   our  network   security   and
     misappropriate our confidential  information,  create system disruptions or
     cause shutdowns.

         Our ownership interest in STOR-Re may lose value or become a liability.
         -----------------------------------------------------------------------

         The  Partnership  has a  1.7%  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. STOR-Re
     provided  limited  property  and  liability   insurance   coverage  to  the
     Partnership,  PS, and affiliates of PS for losses  occurring prior to April
     1, 2004.  Liabilities  for losses and loss adjustment  expenses  include an
     amount  determined  from loss reports and  individual  cases and an amount,
     based on  recommendations  from an outside  actuary that is a member of the
     American Academy of Actuaries,  using a frequency and severity method,  for
     losses  incurred but not  reported.  Determining  the  liability for unpaid
     losses and loss  adjustment  expense is based upon  estimates  and while we
     believe that the amount is adequate,  the ultimate loss may be in excess of
     or less than the amounts  provided,  which may result in a reduction in the
     value of the Partnership's investment or could result in future payments to
     STOR-Re if its reserves were determined to be inadequate.
