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


1.       The accompanying  unaudited  condensed  financial  statements have been
         prepared  pursuant to the rules and  regulations  of the Securities and
         Exchange  Commission.  Certain  information  and  footnote  disclosures
         normally included in financial  statements  prepared in accordance with
         generally accepted accounting principles have been condensed or omitted
         pursuant to such rules and regulations,  although  management  believes
         that  the  disclosures  contained  herein  are  adequate  to  make  the
         information   presented  not  misleading.   These  unaudited  condensed
         financial  statements  should be read in conjunction with the financial
         statements and related notes appearing in the  Partnership's  Form 10-K
         for the year ended December 31, 2000.

2.       In the opinion of  management,  the  accompanying  unaudited  condensed
         financial statements reflect all adjustments, consisting of only normal
         accruals,  necessary  to  present  fairly the  Partnership's  financial
         position at September 30, 2001,  the results of its  operations for the
         three and nine months  ended  September  30, 2001 and 2000 and its cash
         flows for the nine months then ended.

3.       The results of operations for the three and nine months ended September
         30, 2001 are not necessarily indicative of the results expected for the
         full year.

4.       Marketable  securities at September 30, 2001 consist of 381,980  shares
         of common stock and 12,412 shares of Equity  Stock,  Series A of Public
         Storage,  Inc., a publicly  traded real estate  investment  trust and a
         general partner of the Partnership. We have designated our portfolio of
         marketable securities as available for sale. Accordingly,  at September
         30, 2001,  we have  recorded the  marketable  securities at fair value,
         based upon the closing quoted prices of the securities at September 28,
         2001. Changes in market value of marketable securities are reflected as
         unrealized gains or losses directly in Partners' Equity and accordingly
         have no effect on net income.

5.       During September 1998, we borrowed  $21,000,000 from a commercial bank.
         The loan is  unsecured  and  bears  interest  at the  London  Interbank
         Offering Rate,  ("LIBOR") rounded up to the nearest .125% plus 0.60% to
         1.20% depending on our interest  coverage ratio (3.35% at September 30,
         2001).  The loan  requires  monthly  payments of  interest  and matures
         September 2002. Principal may be paid, in whole or in part, at any time
         without penalty or premium.

                                       6



6.       In June  1998,  the  FASB  issued  Statement  of  Financial  Accounting
         Standards No. 133 ("SFAS 133"),  "Accounting for Derivative Instruments
         and  Hedging  Activities,"  as  amended  in June 2000 by  Statement  of
         Financial  Accounting  Standards No. 138 ("SFAS 138"),  "Accounting for
         Certain Derivative  Instruments and Certain Hedging  Activities," which
         requires  companies to recognize  all  derivatives  as either assets or
         liabilities  in the balance sheet and measure such  instruments at fair
         value.  As amended by Statement of Financial  Accounting  Standards No.
         137 ("SFAS 137"),  "Accounting  for Derivative  Instruments and Hedging
         Activities - Deferral of the Effective Date of FASB Statement No. 133,"
         the provisions of SFAS 133 will require  adoption by the Partnership on
         January 1, 2001. The  Partnership  adopted SFAS 133, as amended by SFAS
         138, on January 1, 2001, and the adoption had no material impact on the
         Partnership's consolidated financial statements.

7.       During the third  quarter of 2001,  the  property  manager  changed its
         lease  agreements  in regards to collecting  rent.  New tenants are now
         required  to pay rent in  arrears  as  opposed  to paying  in  advance.
         Primarily  as a  result  of this  change,  rent and  other  receivables
         increased $262,000 and deferred revenue decreased $37,000 from December
         31, 2000.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS


FORWARD LOOKING STATEMENTS
- --------------------------

         When  used  within  this  document,  the words  "expects,"  "believes,"
"anticipates,"  "should,"  "estimates," and similar  expressions are intended to
identify "forward-looking statements" within the meaning of that term in Section
27A of the  Securities  Exchange Act of 1933, as amended,  and in Section 21F of
the Securities Exchange Act of 1934, as amended. Such forward-looking statements
involve known and unknown risks,  uncertainties,  and other  factors,  which may
cause the actual  results and  performance  of the  Partnership to be materially
different  from those  expressed or implied in the forward  looking  statements.
Such factors include the impact of competition from new and existing real estate
facilities  which could  impact  rents and  occupancy  levels at the real estate
facilities that the Partnership has an interest in; the Partnership's ability to
effectively  compete in the markets that it does  business in; the impact of the
regulatory  environment  as  well  as  national,   state,  and  local  laws  and
regulations including, without limitation, those governing Partnerships; and the
impact of general economic  conditions upon rental rates and occupancy levels at
the real estate facilities that the Partnership has an interest in.

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

         THREE AND NINE MONTHS ENDED  SEPTEMBER  30, 2001  COMPARED TO THREE AND
NINE MONTHS ENDED SEPTEMBER 30, 2000:

         Our net  income  for the  nine  months  ended  September  30,  2001 was
$5,404,000  compared to $4,260,000 for the nine months ended September 30, 2000,
representing  an increase  of  $1,144,000  or 27%.  Our net income for the three
months ended  September 30, 2001 was  $2,086,000  compared to $1,640,000 for the
three months ended  September 30, 2000,  representing an increase of $446,000 or
27%. These  increases are primarily a result of increased  operating  results at
our real estate facilities and a decrease in interest expense.

         Rental  income  for the  nine  months  ended  September  30,  2001  was
$8,447,000  compared to $7,114,000 for the nine months ended September 30, 2000,
representing  an  increase of  $1,333,000  or 19%.  Rental  income for the three
months ended  September 30, 2001 was  $3,206,000  compared to $2,422,000 for the
three months ended  September 30, 2000,  representing an increase of $784,000 or
32%.  These  increases are primarily  attributable  to higher rental rates.  The
weighted average occupancy levels at the mini-warehouse  facilities were 92% and
94% for the nine months ended September 30, 2001 and 2000, respectively.  Annual
realized rent for the nine months ended  September 30, 2001  increased to $14.09
per  occupied  square  foot from  $11.69 per  occupied  square foot for the nine
months ended September 30, 2000.

                                       8



         Cost of operations (including management fees paid to an affiliate) for
the nine months ended  September 30, 2001 was $2,553,000  compared to $2,068,000
for the nine  months  ended  September  30,  2000,  representing  an increase of
$485,000  or 23%.  Cost of  operations  (including  management  fees  paid to an
affiliate) for the three months ended September 30, 2001 was $1,132,000 compared
to $685,000 for the three  months ended  September  30,  2000,  representing  an
increase of $447,000 or 65%. This increase is mainly  attributable  to increases
in advertising and promotion expense, and payroll expense.

         During  2001,  we began  offering  containerized  storage at one of our
facilities.  As a result,  we have experienced an increase in both rental income
and cost of  operations,  however,  there  has been no  material  impact  to net
operating income contribution from this property.

         Interest  expense was $218,000 in the nine months ended  September  30,
2001  compared  to  $552,000  in the same  period  in 2000,  a  $334,000  or 61%
decrease.  This decrease is mainly attributable to a lower outstanding principal
balance.

ended September 30, 2001) have been  sufficient to meet all current  obligations
of the Partnership.

         During September 1998, we borrowed  $21,000,000 from a commercial bank.
The loan is unsecured and bears interest at the London  Interbank  Offering Rate
("LIBOR")  rounded up to the nearest .125% plus 0.60% to 1.20%  depending on our
interest coverage ratio (3.35% at September 30, 2001). The loan requires monthly
payments of interest and matures September 2002. Principal may be paid, in whole
or in part, at any time without penalty or premium.

         During the third  quarter of 2001,  the  property  manager  changed its
lease  agreements in regards to collecting rent. New tenants are now required to
pay rent in arrears as opposed to paying in  advance.  Primarily  as a result of
this change, rent and other receivables  increased $262,000 and deferred revenue
decreased $37,000 from December 31, 2000.
