                       PUBLIC STORAGE PROPERTIES XX, INC.
                     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 Company's Form 10-K for the year ended December 31, 1996.

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 Company's  financial position at
     September 30, 1997 and December 31, 1996, the results of its operations for
     the three and nine months  ended  September  30, 1997 and 1996 and its cash
     flows for the nine months then ended.

3.   The results of operations for the three and nine months ended September 30,
     1997 are not  necessarily  indicative of the results  expected for the full
     year.

4.   Certain prior year amounts have been  reclassified in order to conform with
     current year presentation.

5.   In February  1994,  the Company  purchased  10,000  common shares of Public
     Storage,  Inc.,  a publicly  traded  real  estate  investment  trust and an
     affiliate  of  the  Company,  for  $148,000.  The  market  value  of  these
     securities  at  September  30, 1997 was  $296,000.  The Company  recognized
     $2,000  and  $6,000  in  dividends  for the  three  and nine  months  ended
     September 30, 1997, respectively.

6.   The Company has an  unsecured  revolving  credit  facility  with a bank for
     borrowings  up to $750,000 for working  capital  purposes and to repurchase
     the Company's stock.  Outstanding borrowings on the credit facility, at the
     Company's  option,  bear interest at either the bank's prime rate plus .25%
     or the bank's  LIBOR rate plus  2.25%.  Interest  is  payable  monthly.  On
     December 31, 1999,  all unpaid  principal  and accrued  interest is due and
     payable.  At September  30, 1997 and for the nine months then ended,  there

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


     The  following  is   management's   discussion   and  analysis  of  certain
 significant  factors occurring during the periods presented in the accompanying
 Condensed Financial Statements.

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

     The Company's  net income for the nine months ended  September 30, 1997 and
 1996 was $1,126,000 and $1,074,000,  respectively,  representing an increase of
 $52,000 or 5%. Net income for the three  months  ended  September  30, 1997 and
 1996 was  $456,000  and  $413,000,  respectively,  representing  an increase of
 $43,000 or 10%.  These  increases  are  primarily  the result of  increases  in
 property  net  operating   income  (rental  income  less  cost  of  operations,
 management fees paid to affiliate and depreciation expense).

     Rental  income for the nine months  ended  September  30, 1997 and 1996 was
 $2,534,000 and $2,361,000,  respectively,  representing an increase of $173,000
 or 7%. Rental income for the three months ended September 30, 1997 and 1996 was
 $899,000 and $826,000, respectively, representing an increase of $73,000 or 9%.
 These increases are primarily due to increases in rental rates at a majority of
 the Company's mini-warehouse facilities.

     The Company's  mini-warehouse  operations  had weighted  average  occupancy
 levels of 92% and 94% for the nine month periods  ended  September 30, 1997 and
 1996, respectively.

     Cost  of  operations  (including  management  fees  paid to  affiliate  and
 depreciation expense) for the nine months ended September 30, 1997 and 1996 was
 $995,000 and $878,000,  respectively,  representing  an increase of $117,000 or
 13%. Cost of operations for the three months ended  September 30, 1997 and 1996
 was $310,000 and $280,000, respectively, representing an increase of $30,000 or
 11%. The increases  for both the three and nine month  periods ended  September
 30, 1997 compared to 1996 are primarily  attributable  to increases in payroll,
 property taxes, management fees and advertising costs.

     In 1995, the Company  prepaid eight months of 1996  management  fees on its
 mini-warehouse  operations discounted at a 14% effective rate to compensate for
 early  payment.  As a result,  management fee expense for the nine months ended
 September  30,  1996 was  $22,000  lower  than it would  have  been  under  the
 customary, undiscounted fee structure.

     During the nine months  ended  September  30,  1996,  the Company  incurred
 $2,000 in interest expense on its line of credit facility.  No such expense was
 incurred  during  the same  period in 1997 since the  Company  did not have any
 borrowings against its credit facility.

                                       7



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

     The Company  believes  that net cash provided by operating  activities  and
 funds from  operations  (FFO) are important  measures of its  performance.  The
 Company's  financial  profile has been  characterized  by  increasing  net cash
 provided by operating activities and increasing FFO.

     Net  cash  provided  by  operating  activities  for the nine  months  ended
 September 30, 1997 was $1,514,000 compared to $1,468,000 for the same period in
 the prior year.

     The  following  table  summarizes  the  Company's  ability to make  capital
 improvements  to maintain its  facilities  through the use of cash  provided by
 operating  activities.  The remaining  cash flow is available to the Company to
 pay distributions to shareholders and repurchase its stock.

     Funds from operations (FFO) is defined by the Company,  consistent with the
 definition of FFO by the National  Association of Real Estate Investment Trusts
 (NARIET) as net income (loss),  computed in accordance with generally  accepted
 accounting   principles  (GAAP),   before  depreciation  and  extraordinary  or
 non-recurring items. FFO is presented because the Company considers FFO to be a
 useful measure of the operating  performance of a REIT which, together with net
 income  and  cash  flows,  provides  investors  with a basis  to  evaluate  the
 operating  and cash flow  performances  of a REIT.  FFO does not  represent net
 income or cash flows from operations as defined by GAAP. FFO does not take into
 consideration  scheduled  principal payments on debt and capital  improvements.
 Accordingly, FFO is not necessarily a substitute for cash flow or net income as
 a measure of liquidity or operating performance or ability to make acquisitions
 and capital  improvements  or ability to pay  distributions  or debt  principal
 payments.  Also,  FFO as  computed  and  disclosed  by the  Company  may not be
 comparable to FFO computed and disclosed by other REITs.

     Funds from operation for the Company is computed as follows:

     The Company believes that its rental revenues and interest and other income
 will sufficient in the future to meet the Company's operating expenses, capital
 improvements  and  distributions  to  shareholders.  The Company  believes  its
 geographically  diverse  portfolio  has  resulted  in a  relatively  stable and
 predictable investment portfolio.
 
     The Company has an  unsecured  revolving  credit  facility  with a bank for
 borrowings up to $750,000 for working  capital  purposes and to repurchase  the
 Company's  stock.  Outstanding  borrowings  on  the  credit  facility,  at  the
 Company's  option,  bear  interest at either the bank's prime rate plus .25% or
 the bank's LIBOR rate plus 2.25%.  Interest is payable monthly. On December 31,
 1999,  all  unpaid  principal  and  accrued  interest  is due and  payable.  At
 September 30, 1997 and for the nine months then ended, there was no outstanding
 balance on the credit facility.

     The Company's  Board of Directors has authorized the Company to purchase up
 to 300,000  shares of Series A common  stock.  As of September  30,  1997,  the
 Company had repurchased  184,140 shares of Series A common stock, none of which
 were purchased in 1997.

     In February  1994,  the Company  purchased  10,000  common shares of Public
 Storage,  Inc., a publicly traded real estate investment trust and an affiliate
 of the Company, for $148,000. The market value of these securities at September
 30, 1997 was $296,000.  The Company  recognized  $2,000 and $6,000 in dividends
 for the three and nine months ended September 30, 1997, respectively.

     The bylaws of the Company provide that,  during 1999,  unless  shareholders
 have previously  approved such a proposal,  the shareholders  will be presented
 with a proposal to approve or  disapprove  (a) the sale or  financing of all or
 substantially  all of the properties and (b) the  distribution  of the proceeds
 from  such  transaction  and,  in the case of a sale,  the  liquidation  of the
 Company.

     The Company has elected and intends to continue to qualify as a real estate
 investment  trust  ("REIT") for Federal  income tax  purposes.  As a REIT,  the
 Company must meet, among other tests, sources of income,  share ownership,  and
 certain  asset  tests.  The Company is not taxed on that portion of its taxable
 income which is distributed to its  shareholders  provided that at least 95% of
 its taxable income is so distributed to its shareholders prior to filing of the
 Company's tax return.  The primary  difference  between book income and taxable
 income is depreciation expense. In 1996, the Company's Federal tax depreciation
 was $296,000.
