                     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, 1997.

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 March 31, 1998, the results of its operations for the three
         months  ended  March 31, 1998 and 1997 and its cash flows for the three
         months then ended.

3.       The results of operations for the three months ended March 31, 1998 are
         not necessarily indicative of the results expected for the full year.

4.       Marketable  securities  at March 31, 1998 consist of 381,980  shares of
         common stock of Public  Storage,  Inc.,  a publicly  traded real estate
         investment  trust  and  a  general  partner  of  the  Partnership.  The
         Partnership  has designated  its portfolio of marketable  securities as
         available for sale. Accordingly, at March 31, 1998, the Partnership has
         recorded  the  marketable  securities  at fair  value,  based  upon the
         closing quoted prices of the  securities at March 31, 1998.  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.       The Partnership's mortgage note payable matures on October 1, 1998. The
         general  partners  believe the  Partnership  can  refinance the loan on
         terms acceptable to the Partnership upon maturity.

                       PUBLIC STORAGE PROPERTIES IV, LTD.
                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS


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

         Three months ended March 31, 1998  compared to three months ended March
31, 1997:

         The  Partnership's net income for the three months ended March 31, 1998
was  $644,000  compared to $476,000  for the three  months ended March 31, 1997,
representing  an increase of $168,000 or 35%. The increase is primarily a result
of increased  operating results at the Partnership's  mini-warehouse  facilities
combined with decreased interest expense.

         Rental income for the three months ended March 31, 1998 was  $2,110,000
compared to $1,917,000  for the three months ended March 31, 1997,  representing
an increase  of $193,000 or 10%.  This  increase is  primarily  attributable  to
increased occupancy levels and rental rates at the Partnership's  mini-warehouse
facilities.   The  weighted  average  occupancy  levels  at  the  mini-warehouse
facilities  were 94% and 90% for the three months ended March 31, 1998 and 1997,
respectively.  Average monthly  realized rent per occupied square foot increased
from $.81 for the three months ended March 31, 1997 to $.85 for the three months
ended March 31, 1998.

         Interest and other income  decreased  $5,000 for the three months ended
March 31, 1998 compared to the same period in 1997.  The decrease is primarily a
result of  increased  purchase of  marketable  securities  of  affiliate,  which
resulted in lower cash balances and consequently less interest earned.

         Dividend  income from  marketable  securities  of  affiliate  increased
$19,000 for the three months ended March 31, 1998 compared to the same period in
1997 due to an  increase in the number of shares  owned in 1998  compared to the
same period in 1997.

         Cost of operations  (including  management  fees paid to affiliate) for
the three months ended March 31, 1998 was $649,000  compared to $605,000 for the
three months ended March 31,  1997,  representing  an increase of $44,000 or 7%.
This increase is mainly  attributable  to increases in advertising and promotion
costs and property tax expenses.  Property taxes increased due to an increase in
property tax rates at some of the Partnership's mini-warehouse facilities.

         Interest expense decreased $24,000 for the three months ended March 31,
1998  compared  to the  same  period  in 1997  due to a lower  outstanding  loan
balance.


                                       7



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

         Cash flows from operating  activities  ($1,000,000 for the three months
ended March 31, 1998) have been  sufficient to meet all current  obligations  of
the Partnership.

         At March 31, 1997, the Partnership  held 381,980 shares of common stock
with a fair value  totaling  $11,793,000  (cost basis of $6,091,000 at March 31,
1998) in Public Storage,  Inc. The Partnership  recognized  $84,000 in dividends
for the three months ended March 31, 1998.

         In the third quarter of 1991, quarterly distributions were discontinued
to enable the Partnership to make principal  payments that commenced in 1990 and
to increase cash  reserves in  subsequent  years through 1998, at which time the
remaining principal balance is due.

         The Partnership's mortgage note payable matures on October 1, 1998. The
general  partners  believe  the  Partnership  can  refinance  the  loan on terms
acceptable to the Partnership upon maturity.
