         THIS  AGREEMENT  ("Agreement")  is  entered  into as of the 18th day of
September,  1998, by and between PUBLIC STORAGE PROPERTIES IV, LTD. ("Fixed Rate
Payer"), and WELLS FARGO BANK, NATIONAL ASSOCIATION ("Floating Rate Payer").

         WHEREAS,  both Fixed Rate Payer and Floating  Rate Payer seek to reduce
actual or expected  exposure  to changes in interest  rates or to lower costs of
actual or expected borrowings.

         WHEREAS,  the Fixed Rate Payer is willing to make the payments based on
a fixed rate of interest as provided herein; and

         WHEREAS,  the Floating Rate Payer is willing to make the payments based
on a floating rate of interest as provided herein;

         NOW THEREFORE,  in consideration of their mutual covenants,  Fixed Rate
Payer and Floating Rate Payer agree as follows:

         1. DEFINITIONS.  The capitalized terms, "Effective Date", "Fixed Rate",
"Floating Rate", "Floating Rate Maturity",  "Net Swap Settlement Payment Dates",
"Reset Dates", "Swap Amount",  "Termination Date" and "Trade Date" shall each be
as specified in the Swap  Confirmation.  All other  capitalized terms shall have
the meanings set forth below or otherwise as set forth in this Agreement:

                  (a) "BUSINESS DAY" means a day (other than Saturday, Sunday or
holiday) on which Bank is open and conducting its customary banking transactions
in the State of California.

                  (b)  "BUSINESS  DAY   CONVENTION"   means,   for  purposes  of
determining  each  Calculation  Period,  that  convention  specified in the Swap
Confirmation for adjusting any relevant date if it would otherwise fall on a day
that is not a Business Day, so that:

                           (i) if  "following"  is specified,  that date will be
         the first following day that is a Business Day;

                           (ii) if "modified following" is specified,  that date
         will be the first  following day that is a Business Day unless that day
         falls in the next calendar  month,  in which case that date will be the
         first preceding day that is a Business Day; and

                           (iii) if "preceding" is specified,  that date will be
         the first preceding day that is a Business Day.

                  (c)  "CALCULATION  PERIOD" means,  subject to the Business Day
Convention,  each consecutive  period designated in the Swap  Confirmation,  the
first of which will commence on, and include,  the Effective Date and extend to,
but  exclude,  the first Reset Date.  Each  subsequent  Calculation  Period will
commence  on, and  include,  the Reset Date and extend to, but  exclude the next
Reset  Date.  The  final  Calculation  Period  will  end on,  but  exclude,  the
Completion Date.

                  (d) "SWAP CONFIRMATION" means a document, substantially in the
form of Exhibit A hereto,  with the  information  required  in each blank  space
completed.

                  (e) "COMPLETION  DATE" shall mean the Termination  Date unless
an Early Termination Date has occurred,  in which case the Completion Date shall
be the Early Termination Date.

                                       24



                  (f) "DAY COUNT  CONVENTION" means that the calculation of each
Net  Swap  Settlement  will  be  based  on the  actual  number  of  days  in the
Calculation Period divided by a 360-day year.

                  (g) "EARLY  TERMINATION DATE" means the date, if any, prior to
the  Termination  Date upon which  this  Agreement  is  terminated  pursuant  to
Paragraph 3(a) below.

                  (h) "LIBOR" means,  with respect to each  Calculation  Period,
the rate for deposits in U.S.  Dollars for a period  equal to the Floating  Rate
Maturity,  as such rate  appears on  Telerate  Page 3750 as of 11:00 AM,  London
Time,  on the  Reset  Date (or the  Effective  Date in the  case of the  initial
Period).  If such rate does not appear on Telerate Page 3750,  the rate for that
Reset Date will be the  arithmetic  mean of the rates  quoted by major  Banks in
London, selected by Floating Rate Payer, for a period equal to the Floating Rate
Maturity, as of 11:00 AM, London Time, on the Reset Date.

                  (i) "TELERATE PAGE 3750" means the display designated as "Page
3750" on the Dow Jones Telerate  Service (or such other page as may replace Page
3750 on that  service or such other  service as may be  nominated by the British
Bankers'  Association  as the  information  vendor for the purpose of displaying
British  Bankers'   Association   Interest  Settlement  Rates  for  U.S.  Dollar
Deposits).

         2. DETERMINATION; NET SWAP SETTLEMENT PAYMENTS.

                  (a) On the  first  Business  Day  following  the  end of  each
Calculation  Period,  Floating  Rate  Payer will send Fixed Rate Payer a written
notice ("Settlement Notice") specifying:

                           (i) the amount of interest  which would have  accrued
         on the Swap Amount  during the  Calculation  Period at a rate per annum
         equal to the Floating Rate ("Floating Rate Payment").

                           (ii) the amount of interest  which would have accrued
         on the Swap Amount  during the  Calculation  Period at a rate per annum
         equal to the Fixed Rate ("Fixed Rate Payment"); and

                           (iii) the  difference,  if any,  between the Floating
         Rate  Payment  and  the  Fixed  Rate  Payment  ("Net  Swap   Settlement
         Payment").

                  (b) All  calculations  under Paragraph 2(a) above will be made
on the basis of the Day Count Convention.

                  (c) On each Net Swap Settlement Payment Date:

                           (i) if the Fixed Rate  Payment  exceeds the  Floating
         Rate Payment, Fixed Rate Payer shall pay Floating Rate Payer the amount
         of the Net Swap Settlement Payment by, at Floating Rate Payer's option,
         Floating  Rate  Payer's  debiting  Fixed Rate  Payer's  demand  deposit
         account with Floating  Rate Payer,  or by wiring funds to Floating Rate
         Payer; or

                           (ii) if the Floating  Rate Payment  exceeds the Fixed
         Rate Payment, Floating Rate Payer shall pay Fixed Rate Payer the amount
         of the Net Swap Settlement Payment by, at Floating Rate Payer's option,
         crediting  Fixed Rate Payer's demand deposit account with Floating Rate
         Payer, or by wiring funds to a designated Fixed Rate Payer account.

         3. EARLY TERMINATION.

                  (a) This Agreement  shall expire on the  Termination  Date and
neither party may terminate this Agreement prior thereto; provided, however that
in the event that  either  Floating  Rate Payer or Fixed Rate Payer fail to make
any  payment  when due  hereunder  or  otherwise  fail to  perform  any of their
obligations hereunder, unless such default is cured within five Business Days of
the defaulting  party's  receipt of written notice thereof,  the  non-defaulting

                                       25



party may, so long as such default in then  continuing,  upon five Business Days
written notice terminate this Agreement.

                  (b) In the  event of an early  termination  of this  Agreement
pursuant  to  Paragraph  3(a),  the  defaulting  party  shall  promptly  pay the
non-defaulting party, on demand, an amount equal to the Termination Amount. Each
party hereto  acknowledges the Termination Amount to be a reasonable estimate of
the  value,  costs and loss of  compensation  incurred  by the other  party as a
result of the early termination of this Agreement.

                  (c)  "Termination  Amount"  means the  amount in U.S.  Dollars
equal to the arithmetic  mean of the respective  one-time all-in fees (including
documentation  costs)  communicated to the non-defaulting  party on the earliest
practicable  Business Day following the Early  Termination Date by each of three
leading  commercial  banks or  investment  banking firms in San  Francisco,  Los
Angeles or New York  selected in good faith by the  non-defaulting  party as the
fee that it would charge to assume, as of the Early Termination Date, all of the
rights and  obligations of the defaulting  party.  However,  if one or more such
entities  fail so to  communicate  such a fee, the  Termination  Amount shall be
determined on the basis of those fees so communicated by the other entities.

         4.  LIMITATIONS OF LIABILITY.  In no event shall either party hereto be
liable to the other for loss of  profit  or  indirect,  special,  consequential,
punitive or exemplary damages, arising out of any default under this Agreement.

         5. NOTICES. All notices and other communications  required or permitted
to be given  hereunder  shall be in  writing  and  shall be deemed  served  when
personally  delivered  or, if mailed,  upon the first to occur of receipt or the
expiration  of  seventy-two  hours  after  deposit in the United  States  Postal
Service, certified mail, or if sent by overnight courier service, upon the first
to occur of  receipt or 3:00 p.m.  (local  time at place of  delivery)  the next
Business  Day,  addressed  to  Floating  Rate Payer or Fixed Rate Payer at their
respective addresses set forth in the Swap Confirmation.

         6. SUCCESSORS; ASSIGNS. This Agreement shall be binding on and inure to
the benefit of the  successors  and assigns of the parties;  provided,  however,
that Fixed Rate Payer shall not,  without the prior written  consent of Floating
Rate Payer,  assign  (whether by operation of law or  otherwise)  its rights and
obligations  under this Agreement or any interest  herein and any such attempted
assignment shall be void and without force or effect.

         7. GOVERNING LAW. This Agreement  shall be governed by and construed in
accordance  with the laws of the State of  California,  without giving effect to
any choice of law doctrine.

         8. NO THIRD PARTY  BENEFICIARY.  This  Agreement and the payments to be
made by the parties  hereunder are solely for the benefit of the parties  hereto
for the  purposes  stated  herein and no other  person or entity  shall have any
rights  hereunder or be a beneficiary of either party's  obligations  under this
Agreement.

         9.  COUNTERPARTS.  This  Agreement  and the  Swap  Confirmation  may be
executed  in any number of  counterparts  and by each party  hereto on  separate
counterparts,  each of which when  executed and  delivered  shall  constitute an
original,  but all the  counterparts  shall together  constitute but one and the
same instrument.

         10. AMENDMENTS; WAIVERS. Any amendment or waiver of any right under any
provision  of  this  Agreement  shall  be in  writing  and,  in the  case  of an
amendment,  signed by both parties hereto, or in the case of a waiver, signed by
the party  waiving  such right.  No failure or delay by either  party  hereto in
exercising  any right,  power or privilege  hereunder  shall operate as a waiver
thereof.

         11.  TRADE  DATE;  INTEREST  AGREEMENT  NOT  CREDIT  COMMITMENT.   This
Agreement shall be effective at, and as of, 12:01 a.m.,  California time, on the
Trade  Date.  Nothing  in this  Agreement  shall be  construed  to (i) mean that
Floating  Rate Payer is  committed  to make a loan or extend any other credit to
Fixed Rate Payer,  or (ii) amend or modify any contract,  instrument or document
executed in connection with the Loan Facility.

                                       26
