                                     PART I.

ITEM 1.  BUSINESS
         --------

General
- -------

     Public  Storage  Properties  XX,  Inc.  (the  "Company")  is a real  estate
investment trust ("REIT") organized as a California  corporation that was formed
to succeed to the business of Public  Storage  Properties XX, Ltd., a California
limited  partnership  (the  "Partnership"),   in  a  reorganization  transaction
completed on August 27, 1991.

     The Partnership offered 100,000 units of limited partnership  interest (the
"Units") to the public in July 1989;  41,377 units were sold. The  Partnership's
general partners were PSI Associates II, Inc. ("PSA"), a California corporation,
and  B.  Wayne  Hughes  ("Hughes").  PSA  was an  affiliate  of  Public  Storage
Management, Inc., a California corporation (see below).

     Effective  August 27, 1991, the  Partnership  transferred all of its assets
and liabilities to the Company pursuant to a plan of Reorganization  approved by
a majority of the limited partners. In exchange for the Partnership's assets and
liabilities,  the  Company  issued  1,044,874  shares of common  stock  Series A
("Series A shares"),  90,859 shares of common stock Series B ("Series B shares")
and 257,432  shares of common  stock Series C ("Series C shares") of the Company
to the Partnership.  The Partnership then made a liquidating distribution to the
limited partners by distributing 99 percent of the Series A shares (on the basis
of 25 Series A shares for each  Unit).  The  remaining 1 percent of the Series A
shares and all of the Series B shares and Series C shares  were  distributed  to
the  general  partners  in  respect  of  their  interests  in  the  Partnership.
Subsequent thereto, the Partnership was dissolved. The Company has elected to be
taxed as a REIT for Federal income tax purposes.

     The Company is a finite life REIT, with a term until December 31, 2038 (the
same  as the  predecessor  Partnership).  However,  pursuant  to  the  Company's
by-laws, in 1999 the Company will be required to present the shareholders with a
proposal for the sale or financing of the properties and, in the case of a sale,
a liquidation of the Company,  unless the  properties  have already been sold or
financed. See " Sale or Financing" below.

     The Company's  investment  objectives  are (as were the  Partnership's)  to
maximize cash flow from operations and to maximize capital appreciation.

     The Company has acquired 7 properties,  all of which are in operation.  The
Company   believes   that  its   mini-warehouses   have   attractive   operating
characteristics.

     In 1995,  there were a series of mergers among Public  Storage  Management,
Inc. (which was the Company's mini-warehouse operator), Public Storage, Inc. and
their affiliates  (collectively,  "PSMI"),  culminating in the November 16, 1995
merger (the "PSMI Merger") of PSMI into Storage Equities, Inc., a REIT listed on
the New York Stock  Exchange.  In the PSMI Merger,  Storage  Equities,  Inc. was
renamed  Public  Storage,  Inc.  ("PSI") and PSI acquired  substantially  all of
PSMI's  United  States real  estate  operations  and became the  operator of the
Company's  mini-warehouse  properties.  Hughes,  the Company's  Chief  Executive
Officer,  and  members  of his  family  (the  "Hughes  Family")  are  the  major
shareholders of PSI. As a result of the PSMI Merger,  PSI owns all of the shares
of the Company's common stock that was owned by PSMI or its affiliates,  and PSI
has an option to acquire all of the shares of the  Company's  common stock owned
by Hughes.

Investments in Facilities
- -------------------------

     At December 31, 1997, the Company owned 7 mini-warehouse facilities located
in 5 states:  California (2), Illinois (2), Minnesota (1), Missouri (1) and Ohio
(1).

     The  Company  believes  that its  operating  results  have  benefited  from
favorable   industry   trends  and  conditions.   Notably,   the  level  of  new
mini-warehouse construction has decreased somewhat from the peak mid-1980 levels
while consumer demand has increased. In addition, the Company's  mini-warehouses
are  characterized  by a low level of capital  expenditures  to  maintain  their
condition and appearance.
                                       2

     Mini-warehouses

     Mini-warehouses,  which comprise the Company's investments, are designed to
offer accessible storage space for personal and business use at a relatively low
cost. A user rents a fully enclosed space which is for the user's  exclusive use
and to which only the user has access on an  unrestricted  basis during business
hours.  On-site  operation is the  responsibility  of resident  managers who are
supervised  by  area  managers.   Some  mini-warehouses  also  include  rentable
uncovered parking areas for vehicle storage. Leases for mini-warehouse space may
be on a long-term or short-term basis, although typically spaces are rented on a
month-to-month  basis.  Rental  rates  vary  according  to the  location  of the
property and the size of the storage space.

     Users of space in  mini-warehouses  include both  individuals and large and
small  businesses.  Individuals  usually employ this space for storage of, among
other  things,  furniture,  household  appliances,  personal  belongings,  motor
vehicles,  boats,  campers,  motorcycles and other household  goods.  Businesses
normally employ this space for storage of excess  inventory,  business  records,
seasonal goods, equipment and fixtures.

     Mini-warehouses  in which the Company  has  invested  generally  consist of
three to seven  buildings  containing an aggregate of between 350 to 750 storage
spaces, most of which have between 25 and 400 square feet and an interior height
of approximately 8 to 12 feet.

     The Company experiences minor seasonal fluctuations in the occupancy levels
of  mini-warehouses  with  occupancies  higher in the summer  months than in the
winter months. The Company believes that these fluctuations  result in part from
increased moving activity during the summer.

     The  Company's  mini-warehouses  are  geographically  diversified  and  are
generally  located in heavily  populated  areas and close to  concentrations  of
apartment  complexes,  single family  residences  and  commercial  developments.
However,  there may be  circumstances  in which it may be  appropriate  to own a
property  in a less  populated  area,  for  example,  in an area  that is highly
visible  from a major  thoroughfare  and  close to,  although  not in, a heavily
populated area. Moreover,  in certain population centers,  land costs and zoning
restrictions may create a demand for space in nearby less populated areas.

     As with most other types of real estate,  the conversion of mini-warehouses
to  alternative  uses in  connection  with a sale or otherwise  would  generally
require substantial capital  expenditures.  However, the Company does not intend
to convert its mini-warehouses to other uses.

Operating Strategies
- --------------------

     The  Company's  mini-warehouses  are  operated  by PSI  under  the  "Public
Storage" name,  which the Company  believes is the most  recognized  name in the
mini-warehouse   industry.   The  major  elements  of  the  Company's  operating
strategies are as follows:

*    Capitalize on "Public  Storage's" name recognition.  PSI, together with its
     predecessor,  has  more  than  20  years  of  operating  experience  in the
     mini-warehouse  business, and is the largest operator of mini-warehouses in
     the United States. PSI believes that its marketing and advertising programs
     improve its competitive position in the market. PSI's in-house Yellow Pages
     staff designs and places  advertisements  in approximately 700 directories.
     Commencing  in  early  1996,  PSI  began  to  experiment  with a  telephone
     reservation  system designed to provide added customer  service.  Customers
     calling either PSI's toll-free  telephone referral system,  (800) 44-STORE,
     or a mini-warehouse facility are directed to PSI's reservation system where
     a trained  representative  discusses with the customer space  requirements,
     price and  location  preferences  and also  informs  the  customer of other
     products and services  provided by PSI. The  telephone  reservation  system
     supports  rental  activity  at  all  of  the  Company's  properties.  PSI's
     toll-free  telephone referral system services  approximately  160,000 calls
     per month from  potential  customers  inquiring  as to the  nearest  Public
     Storage mini-warehouse.

*    Maintain  high  occupancy  levels  and  increase  realized  rents.  Average
     occupancy for the Company's  mini-warehouses has decreased from 94% in 1996
     to 92% in 1997.  Realized  monthly rents per occupied square foot increased
     from $8.45 in 1996 to $9.28 in 1997.

                                       3
<PAGE>

*    Systems and controls.  PSI has an  organizational  structure and a property
     operation system, "CHAMP" (Computerized Help and Management Program), which
     links its corporate  office with each  mini-warehouse.  This enables PSI to
     obtain  daily   information  from  each   mini-warehouse   and  to  achieve
     efficiencies in operations and maintain  control over its space  inventory,
     rental rates,  promotional discounts and delinquencies.  Expense management
     is achieved through  centralized payroll and accounts payable systems and a
     comprehensive  property  tax appeals  department,  and PSI has an extensive
     internal  audit  program   designed  to  ensure  proper  handling  of  cash
     collections.

*    Professional  property  operation.  In  addition to the  approximately  150
     support  personnel  at the  Public  Storage  corporate  offices,  there are
     approximately 2,700 on-site personnel who manage the day-to-day  operations
     of  the  mini-warehouses  in  the  Public  Storage  system.  These  on-site
     personnel are supervised by 110 district managers, 15 regional managers and
     three divisional  managers (with an average of 13 years'  experience in the
     mini-warehouse  industry) who report to the president of the mini-warehouse
     property  operator (who has 12 years of experience  with the Public Storage
     organization). PSI carefully selects and extensively trains the operational
     and  support  personnel  and offers them a  progressive  career  path.  See
     "Property Operator."

Property Operator
- -----------------

     The  Company's  mini-warehouse  properties  are  managed  by  PSI  under  a
Management Agreement (as amended, the "Management Agreement").

     Under the supervision of the Company,  PSI coordinates the operation of the
facilities,  establishes rental policies and rates,  directs marketing activity,
and directs the purchase of equipment and supplies,  maintenance  activity,  and
the  selection  and  engagement  of  all  vendors,   supplies  and   independent
contractors.

     PSI engages, at the expense of the Company,  employees for the operation of
the Company's  facilities,  including  resident  managers,  assistant  managers,
relief  managers,  and billing and maintenance  personnel.  Some or all of these
employees may be employed on a part-time basis and may also be employed by other
persons,  partnerships,  REITs or other entities owning  facilities  operated by
PSI.

     In the  purchasing of services  such as  advertising  (including  broadcast
media advertising) and insurance, PSI attempts to achieve economies by combining
the resources of the various facilities that it operates. Facilities operated by
PSI  have  historically  carried   comprehensive   insurance,   including  fire,
earthquake, liability and extended coverage.

     PSI has  developed  systems for space  inventory,  accounting  and handling
delinquent  accounts,  including a  computerized  network  linking PSI  operated
facilities. Each project manager is furnished with detailed operating procedures
and typically  receives  facilities  management  training from PSI. Form letters
covering a variety of circumstances are also supplied to the project managers. A
record of actions  taken by the project  managers  when  delinquencies  occur is
maintained.

     The Company's  facilities  are  typically  advertised  via signage,  yellow
pages,  flyers  and  broadcast  media  advertising  (television  and  radio)  in
geographic  areas  in  which  many  of the  Company's  facilities  are  located.
Broadcast  media  and  other  advertising  costs are  charged  to the  Company's
facilities located in geographic areas affected by the advertising. From time to
time, PSI adopts  promotional  programs,  such as temporary rent reductions,  in
selected areas or for individual facilities.

     For as long as the Management  Agreement is in effect,  PSI has granted the
Company  a  non-exclusive  license  to use two PSI  service  marks  and  related
designs,  including the "Public  Storage" name, in  conjunction  with rental and
operation of  facilities  managed  pursuant to the  Management  Agreement.  Upon
termination  of the Management  Agreement,  the Company would no longer have the
right to use the service marks and related  designs  except as described  below.
Management  believes  that the loss of the  right to use the  service  marks and
related designs could have a material adverse effect on the Company's business.

     The Management  Agreement,  as amended in February 1995,  provides that (i)
the Management  Agreement will expire in February 2002 provided that in February
of  each  year  it  shall  be  automatically  extended  for  one  year  (thereby
maintaining a seven-year  term) unless either party  notifies the other that the
Management  Agreement  is not being  extended,  in which  case it expires on the
first  anniversary  of  its  then  scheduled  expiration  date.  The  Management
Agreement may also be  terminated  by either party for cause,  but if terminated
for cause by the  Company,  the  Company  retains  the rights to use the service
marks  and  related  designs  until  the  then  scheduled  expiration  date,  if
applicable, or otherwise a date seven years after such termination.
 
                                      4

     Certain of the directors and officers of the Company are also directors and
officers of PSI.

Competition
- -----------

     Competition  in  the  market  areas  in  which  the  Company   operates  is
significant  and  affects  the  occupancy  levels,  rental  rates and  operating
expenses of certain of the Company's facilities.  Competition may be accelerated
by any increase in availability  of funds for investment in real estate.  Recent
increases in plans for  development  of  mini-warehouses  is expected to further
intensify competition among mini-warehouse operators in certain market areas. In
addition to competition  from  mini-warehouses  operated by PSI, there are three
other  national  firms and numerous  regional and local  operators.  The Company
believes  that  the  significant  operating  and  financial  experience  of  its
executive  officers and directors,  PSI and the "Public  Storage"  name,  should
enable the Company to continue to compete effectively with other entities.

Other Business Activities
- -------------------------

     A corporation owned by the Hughes Family reinsures  policies against losses
to goods  stored  by  tenants  in the  Company's  mini-warehouses.  The  Company
believes that the availability of insurance  reduces the potential  liability of
the Company to tenants for losses to their goods from theft or destruction. This
corporation  receives  the  premiums  and bears the  risks  associated  with the
insurance.

     A  corporation,  in which PSI has a 95%  economic  interest  and the Hughes
Family has a 5% economic interest,  sells locks, boxes and tape to tenants to be
used in securing  their  spaces and moving their  goods.  PSI believes  that the
availability of locks, boxes and tape for sale promotes the rental of spaces.

Sale or Financing
- -----------------

     The by-laws 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.

Employees
- ---------

     As of December  31,  1997,  the Company  had 28  employees,  14 persons who
render services on behalf of the Company on a full-time basis and 14 persons who
render services on a part-time basis (6 of whom were executive officers).  These
persons include resident managers, assistant managers, relief managers, district
managers, and administrative and maintenance personnel.

Federal Income Tax
- ------------------

     The Company  intends to continue to operate in a manner so as to qualify as
a REIT under the Internal Revenue Code of 1986, as amended, but no assurance can
be given that the Company  will be able to continue to qualify at all times.  By
qualifying  as a REIT,  the Company  can deduct  dividend  distributions  to its
shareholders for Federal income tax purposes,  thus effectively  eliminating the
"double  taxation"  (at the  corporate and  shareholder  levels) that  typically
applies to corporate  dividends.  The Company  believes it is in compliance with
these  requirements  and,  accordingly,  no provision  for income taxes has been
made.

Year 2000 Compliance
- --------------------

     PSI has  completed  an initial  assessment  of its  computer  systems.  The
majority of the computer  programs were  installed or upgraded over the past few
years and are Year 2000 compliant.  Some of the older computer programs utilized
by PSI were written  without  regard for Year 2000 issues and could
cause  a  system  failure  or  miscalculations   with  possible   disruption  of
operations. Each of these computer programs and systems has been evaluated to be
upgraded or replaced as part of PSI Year 2000 project.

     The cost of the Year 2000 project will be allocated to all  companies  that
use the PSI  computer  systems.  The  cost of the  Year  2000  project  which is
expected to be allocated to the Company is less than $30,000.  This cost will be
expensed as incurred.

                                       5
<PAGE>

     The project is expected to be completed by March 31, 1999 which is prior to
any   anticipated   impact  on  operating   systems.   PSI  believes  that  with
modifications to existing software and, in some instances, the conversion to new
software,  the Year 2000 issue will not pose significant  operational  problems.
However,  if such  modifications are not made, or are not completed timely,  the
Year 2000 issue could have a material impact on the operations of the Company.

     The  costs  of the  project  and the  date on which  PSI  believes  it will
complete the Year 2000  modifications  are based on management's best estimates,
which were derived utilizing numerous assumptions of future events. There can be
no guarantee  that these  estimates  will be achieved and actual  results  could
differ materially from those anticipated.

Proposed Merger
- ---------------

     In  February  1998,  the  Company  and  PSI  agreed,   subject  to  certain
conditions,  to merge. Upon the merger,  each outstanding share of the Company's
common  stock  series A (other  than  shares  held by PSI or by  holders  of the
Company's  common stock  series A ("Series A  Shareholders")  who have  properly
exercised dissenters' rights under California law ("Dissenting Shares")) will be
converted  into the right to receive cash,  PSI common stock or a combination of
the two,  as  follows:  (i) with  respect  to a certain  number of shares of the
Company's  common  stock series A (not to exceed 20% of the  outstanding  common
stock  series A of the Company,  less any  Dissenting  Shares),  upon a Series A
Shareholder's election,  $22.57 in cash, subject to reduction as described below
or (ii)  that  number  (subject  to  rounding)  of shares  of PSI  common  stock
determined by dividing  $22.57,  subject to reduction as described below, by the
average of the per share  closing  prices on the New York Stock  Exchange of PSI
common stock during the 20 consecutive  trading days ending on the fifth trading
day  prior  to  the  special   meeting  of  the  Company's   shareholders.   The
consideration  paid by PSI to the Series A  Shareholders  in the merger  will be
reduced by the amount of cash distributions  required to be paid to the Series A
Shareholders  by the Company  prior to  completion  of the merger  (estimated at
$0.93  per  share)  in  order  to  satisfy  the  Company's   REIT   distribution
requirements ("Required REIT Distributions").  The consideration received by the
Series A  Shareholders  in the merger,  however,  along with any  Required  REIT
Distributions,  will not be less than $22.57 per share of the  Company's  common
stock series A, which amount  represents  the market value of the Company's real
estate  assets at  October  1,  1997  (based on an  independent  appraisal)  and
interest of the Series A  Shareholders  in the  estimated net asset value of its
other assets at April 30,  1998.  Additional  distributions  will be made to the
Series A Shareholders to cause the Company's estimated net asset value allocable
to the Series A  Shareholders  as of the date of the merger to be  substantially
equivalent  to $22.57 per share.  Upon the merger,  each share of the  Company's
common  stock series B and common stock series C (other than shares held by PSI)
would be converted  into the right to receive $10.90 in PSI common stock (valued
as in the case of the Company's  common stock series A) plus (i) any  additional
distributions  equal to the amount by which the  Company's  estimated  net asset
value  allocable to the holders of the Company's  common stock series B and C as
of the date of the  merger  exceeds  $10.90  per  share  and (ii) the  estimated
Required REIT Distributions payable to the holders of the Company's common stock
series B of $0.93 per share. The common stock of the Company held by PSI will be

     Substantially  all of the Company's  facilities  were acquired prior to the
time that it was customary to conduct environmental investigations in connection
with  property  acquisitions.  During the fourth  quarter of 1995,  the  Company
completed   environmental   assessments   of  its  properties  to  evaluate  the
environmental  condition of, and  potential  environmental  liabilities  of such
properties.  These  assessments  were performed by an independent  environmental
consulting firm. Based on the assessments, the Company expensed $156,000 in 1995
for known environmental remediation requirements.

     The  Company's  properties  are operated to maximize  cash flow through the
regular  review of and,  when  warranted by market  conditions,  adjustments  to
scheduled  rents.  As reflected in the table below,  the Company has experienced
overall improved property operations:

(1)  Realized  rent per square foot  represents  the actual  revenue  earned per
     occupied square foot.  Management  believes this is a more relevant measure
     than the posted rental rates,  since posted rates can be discounted through
     the use of promotions. Includes administrative and late fees.
(2)  Operating margin (before reduction for depreciation expense) is computed by
     dividing rental income less cost of operations by rental income.  Operating
     margin (after reduction for  depreciation  expense) is computed by dividing
     rental income less cost of operations and depreciation by rental income.

Act of 1934 and no public  trading  market  exists for the Series B and Series C
shares.

     The Company's  Articles of  Incorporation  provide that the Series B shares
and  Series  C shares  will  convert  automatically  into  Series A shares  on a
share-for-share  basis (the "Conversion") when (A) the sum of (1) all cumulative
dividends  and other  distributions  from all sources  paid with  respect to the
Series A shares (including liquidating distributions, but not including payments
made to redeem  such stock  other than in  liquidation)  and (2) the  cumulative
Partnership  distributions from all sources with respect to all Units (including
the General  Partners' 1% interest)  equals (B) the product of $20 multiplied by
the  number  of the  then  outstanding  "Original  Series  A  shares".  The term
"Original   Series  A  shares"   means  the  Series  A  shares   issued  in  the
Reorganization.

     In general,  the Series A shares,  Series B shares and Series C shares have
equal voting rights.  The Company's  bylaws provide that during the period prior

"General  Partners") or their  successors in interest as holders of Series B and
Series C shares,  other than the  election  and removal of  directors  and other
proposals  relating to the control of the Company and its business,  the General
Partners and any  successors  in interest have agreed to vote their Series B and

     As of December 31, 1997, there were  approximately 653 holders of record of
the Company's Series A shares.

     Holders of Series A shares are entitled to receive  distributions  when, as
and if declared by the Board of Directors out of any funds legally available for
that purpose. The Company, as a REIT, is required to distribute, prior to filing
its tax  return,  at least  95% of its "real  estate  investment  trust  taxable
income,"  which,  as defined by the relevant tax  statutes and  regulations,  is
generally   equivalent   to  net  taxable   ordinary   income.   Under   certain
circumstances,  the  Company  can  rectify a failure  to meet this  distribution
requirement by paying dividends after the close of a particular taxable year.

     A principal policy of the Company is to make quarterly cash  distributions.
The Company  intends to make quarterly cash  distributions  out of funds legally
available, as determined by the Company's Board of Directors.

     For Federal income tax purposes,  distributions to shareholders are treated
as ordinary income,  capital gains, return of capital or a combination  thereof,
and for the past three years all distributions  have been classified as ordinary
income.

     Under generally accepted accounting principles, the amount of distributions
declared to shareholders exceeded income by $80,000 during 1996.

     Series A shares are entitled to participate  equally in distributions  when
declared  by the  Board  of  Directors  and in the  Company's  net  assets  upon
dissolution and liquidation  after repayment of the Company's  liabilities.  The
Series B shares (prior to  conversion  into Series A shares) are not entitled to
participate  in  distributions  attributable  to  sales  or  financings  of  the
properties or the  liquidation  of the Company,  but will  participate  in other
distributions  on the same  basis as the  Series A shares.  The  Series C shares
(prior to conversion  into Series A shares) are not entitled to  participate  in
any distributions, including liquidating distributions.

Repurchase of Company's common stock
- ------------------------------------

     If  considered  to be an  attractive  investment  opportunity  or in  other
appropriate circumstances, the Company may repurchase its Series A shares out of
legally available funds, if approved by the Board of Directors.

     The Board of  Directors  has  authorized  the Company to  repurchase  up to
300,000 Series A shares.  Through 1996, the Company repurchased 184,140 Series A
shares.  No Series A shares were  repurchased  in 1997 or through  February  28,
1998.

ITEM 6.  SELECTED FINANCIAL DATA (CONTINUED)
         -----------------------------------

(1)  Funds from operations (FFO) is defined by the Company,  consistent with the
     definition  of FFO by the National  Association  of Real Estate  Investment
     Trusts  (NAREIT),  as  net  income  (loss)  (computed  in  accordance  with
     generally  accepted   accounting   principles)   before   depreciation  and
     extraordinary or non-recurring items. FFO is presented because the Company,
     as well as many  industry  analysts,  consider FFO to be one measure of the
     performance of the Company,  ie, one that generally reflects changes in the
     Company's  net  operating  income.  FFO does not  take  into  consideration
     scheduled principal payments on debt and capital improvements. Accordingly,
     FFO is not  necessarily  a substitute  for the  Company's  cash flow or net
     income as a measure of the Company's liquidity or operating  performance or
     ability to pay  distributions.  Furthermore,  the NAREIT  definition of FFO
     does not address the  treatment of certain items and all REITs do not treat
     items the same way in computing FFO. Accordingly,  comparisons of levels of
     FFO among REITs may not necessarily be meaningful.

(2)  Net  income  per share is  presented  on a basic  and  diluted  basis.  The
     earnings per share amount prior to 1997 have been  reflected as required to
     comply with statement of Financial  Accounting  Standards No. 128, Earnings
     per Share.  For further  discussion of earnings per share and the impact of
     Statement No. 128, see notes to the financial  statements beginning on page
     F-6.  Basic  earnings  per share  represents  the  shareholders'  rights to
     distribution out of the respective period's net income, which is calculated
     by dividing net income after  reduction for any  distributions  made to the
     holders of the Company Common Stock Series B (holders of the Company Common
     Stock  Series C are not  entitled to cash  distributions)  by the  weighted
     average  number of shares of the Company Common Stock Series A. (See note 4
     below.) Diluted earnings per share assumes conversion of the Company Common
     Stock Series B and C into the Company Common Stock Series A.

(3)  In connection  with the  reorganizations  of the Company  Partnership,  the
     Company  issued the  Company  Common  Stock  Series A, B and C. The capital
     structure of the Company was designed to reflect the economic rights of the
     limited  partners and general  partners in the Company  Partnership and the
     capital  shares were  distributed  to the  limited and general  partners in
     respect of their interest in the Company Partnership.

     The  Company  Common  Stock  Series A shares are  entitled  to 100% of cash
     distributions from operations from the Company until (a) the sum of (1) all
     cumulative  dividends  and  other  distributions  from all  sources  to the
     holders of the Common  Stock  Series A shares  and (2) the  cumulative  the
     Company  distributions from all sources with respect to all units equal (b)
     the product of $20 multiplied by the number of the then-outstanding "Common
     Stock Series A shares," at which time the Company Common Stock Series B and
     Common  Stock  Series C shares  will  automatically  convert to the Company
     Common Stock Series A shares ("Conversion").

     As of  December  31,  1997,  Conversion  will  occur  when  $10,046,000  in
     additional  distributions  are made to holders of the Company  Common Stock
     Series A  (assuming  no further  repurchases  of the Company  Common  Stock
     Series A).

(4)  For federal income tax purposes,  distributions on the Company Common Stock
     for 1993, 1994,  1995,  1996, and 1997 were from ordinary income.  For GAAP
     income purposes, distributions exceeded net income in 1993, 1994, 1995, and
     1996  by   $157,000,   $19,000,   $287,000,   and   $80,000   respectively.
     Distributions  for each year  include  distributions  declared  during  the
     fourth quarter and paid in January.  The difference  between the components
     of distributions  for GAAP purposes and tax purposes results primarily from
     the methods used to compute depreciation expense.

(5)  Book value per share  computed based on the number of shares of the Company
     Common Stock Series A, B and C outstanding at the end of the period.

ITEM 7.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
         OF OPERATIONS.
         ----------------------------------------------------------------------

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

     YEAR ENDED  DECEMBER  31, 1997  COMPARED TO YEAR ENDED  DECEMBER  31, 1996.
     --------------------------------------------------------------------------
Netincome in 1997 was $1,509,000 compared to $1,439,000 in 1996, representing an
increase  of $70,000 or 5%. Net income per  diluted  Series A share was $1.25 in
1997  compared  to $1.18 in 1996,  representing  an  increase  of $.07 or 6% per
share. These increases are due to an increase in property net operating income.

     During 1997,  property net  operating  income  (rental  income less cost of
operations,  management  fees paid to an  affiliate  and  depreciation  expense)
increased  $66,000 from  $1,509,000 in 1996 to $1,575,000 in 1997. This increase
is attributable to an increase in rental income at the Company's  mini-warehouse
operations.

     Rental income for the  mini-warehouse  operations  increased $228,000 or 7%
from  $3,192,000 in 1996 to $3,420,000  in 1997.  Cost of operations  (including
management fees paid to an affiliate of the Company)  increased  $156,000 or 13%
from  $1,214,000 in 1996 to $1,370,000 in 1997. The results of these changes was
a net increase in property net operating income before  depreciation  expense of
$72,000 or 4% from  $1,978,000  in 1996 to  $2,050,000  in 1997.  Rental  income
increased  primarily  due to an  increase  in  rental  rates at all seven of the
Company's  properties.  The  increase  in cost of  operations  is mainly  due to
increases in management fees, payroll, advertising and property tax expense.

     Weighted  average   occupancy  levels  for  the  Company's   mini-warehouse
facilities were 92% and 94% in 1997 and 1996, respectively.

     In 1995, the Company  prepaid eight months of 1996  management  fees on its
mini-warehouse  discounted at the rate of 14% per year to  compensate  for early
payment. As a result, management fee expense for the twelve month ended December
31,  1996 was  $22,000  lower  than it would have  without  the  discounted  fee
structure.


     YEAR ENDED  DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995. 
     -----------------------------------------------------------------------
Net  income   in   1996   was  $1,439,000  compared  to  $1,085,000  in  1995,
representing  an increase of  $354,000 or 33%.  Net income per diluted  Series A
share was $1.18 in 1996  compared to $.85 in 1995,  representing  an increase of
$.33 or 39% per share.  These  increases  are  primarily  due to an  increase in
property net operating income combined with the favorable impact of comparing to
expenses  for 1995 which  included  a  non-recurring  charge  for  environmental
assessments and provision for future remediation costs.

     During 1996,  property net  operating  income  (rental  income less cost of
operations,  management  fees paid to an  affiliate  and  depreciation  expense)
increased  $211,000 from $1,298,000 in 1995 to $1,509,000 in 1996. This increase
is  primarily  attributable  to an  increase in rental  income at the  Company's
mini-warehouse operations.

     Rental income for the mini-warehouse  operations  increased $279,000 or 10%
from  $2,913,000 in 1995 to $3,192,000  in 1996.  Cost of operations  (including
management  fees paid to an affiliate of the  Company)  increased  $70,000 or 6%
from  $1,144,000 in 1995 to $1,214,000 in 1996. The results of these changes was
a net increase in property net operating income before  depreciation  expense of
$209,000 or 12% from  $1,769,000 in 1995 to  $1,978,000  in 1996.  Rental income
increased  primarily  due to an  increase  in  rental  rates at all seven of the
Company's  properties.  The  increase  in cost of  operations  is mainly  due to
increases in payroll,  advertising  and  property  tax expense.  The increase in
property taxes is mainly  attributable  to a one-time tax refund received at the
Company's Los Angeles,  California  property in early 1995 from appealing  prior
years tax assessments.

     Weighted  average   occupancy  levels  for  the  Company's   mini-warehouse
facilities were 94% and 92% in 1996 and 1995, respectively.

     In 1995, the Company  prepaid eight months of 1996  management  fees on its
mini-warehouse  operations  (based  on the  management  fees for the  comparable
period during the calendar year immediately preceding the prepayment) discounted
at the  rate of 14% per year to  compensate  for  early  payment.  In 1996,  the
Company  expensed  the  prepaid  management  fees.  The  amount is  included  in
management  fees paid to affiliate in the  statements of income.  As a result of
the  prepayment,  the Company saved  approximately  $22,000 in management  fees,
based on the  management  fees that  would have been  payable  on rental  income
generated in 1996 compared to the amount prepaid.

(1)  Realized  rent per square foot  represents  the actual  revenue  earned per
     occupied square foot.  Management  believes this is a more relevant measure
     than the posted rental rates,  since posted rates can be discounted through
     the use of promotions. Includes administrative and late fees.
(2)  Operating margin (before reduction for depreciation expense) is computed by
     dividing rental income less cost of operations by rental income.  Operating
     margin (after reduction for  depreciation  expense) is computed by dividing
     rental income less cost of operations and depreciation by rental income.

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

     CAPITAL STRUCTURE.  The Company's  financial profile has been characterized
by increasing net income,  increasing cash provided by operating  activities and
increasing funds from operations ("FFO").

     NET CASH PROVIDED BY OPERATING  ACTIVITIES AND FUNDS FROM  OPERATIONS.  The
Company believes that important measures of its performance as well as liquidity
are net cash provided by operating activities and FFO.

     Net cash provided by operating  activities  (net income plus  depreciation)
reflects the cash generated from the Company's business before  distributions to
shareholders,  capital  expenditures  and principal  payments on debt.  Net cash
provided  by  operating  activities  has  increased  over  the past  years  from
$1,629,000 in 1995 to $2,016,000 in 1997.

     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 LIBOR
rate plus 2.25%.  Interest is payable  monthly until  maturity.  On December 31,
1999, all unpaid principal and accrued  interest is due and payable.  During the
first quarter of 1996, the Company  borrowed and repaid  $150,000 on its line of
credit facility.  At December 31, 1997, there was no outstanding  balance on the
credit facility.

     The  following  table  summarizes  the  Company's  ability to make  capital

</TABLE>

     The Company believes that its rental revenues and interest and other income
will be  sufficient  over at least the next twelve  months to meet the Company's
operating expenses, capital improvements and distributions to shareholders.  For
1997,  the Company  anticipates  expending  approximately  $159,000  for capital
improvements.  During 1995, the Company's  property operator commenced a program
to enhance the visual appearance of the  mini-warehouse  facilities  operated by
it.  Such  enhancements   include  new  signs,   exterior  color  schemes,   and
improvements  to the rental offices.  The vast majority of the costs  associated
with these enhancements were incurred in 1995 and 1996.

     FFO is defined by the Company, consistent with the definition of FFO by the
National  Association of Real Estate Investment  Trusts (NAREIT),  as net income
(loss) (computed in accordance with generally  accepted  accounting  principles)
before depreciation and extraordinary or non-recurring  items. FFO for the years
ended December 31, 1997 and 1996 was $1,984,000  and  $1,908,000,  respectively.
FFO is  presented  because  the  Company,  as well as  many  industry  analysts,
consider FFO to be one measure of the performance of the Company, i.e., one that
generally  reflects changes in the Company's net operating income.  FFO does not
take  into  consideration  scheduled  principal  payments  on debt  and  capital
improvements. Accordingly, FFO is not necessarily a substitute for the Company's
cash flow or net income,  as a measure of the  Company's  liquidity or operating
performance or ability to pay distributions.  Furthermore, the NAREIT definition
of FFO does not  address  the  treatment  of certain  items and all REITs do not
treat items the same way in computing FFO. Accordingly, comparisons of levels of
FFO among REITs may not necessarily be meaningful.

     Funds from operations is computed as follows:

     In February  1994,  the Company  purchased  10,000  common shares of Public
Storage,  Inc.  ("PSI"),  a publicly traded real estate  investment trust and an
affiliate of the Company, for $148,000.  The market value of these securities at
December  31, 1997 was  $294,000.  The Company  recognized  $9,000 in  dividends
during 1997 and 1996.

     The Company believes its geographically diverse portfolio has resulted in a
relatively stable and predictable investment portfolio.

     On November 12, 1997, the Company's  Board of Directors  declared a regular
quarterly  distribution  per share of $0.28.  In addition,  consistent  with the
Company's  REIT  distribution  requirements,  the  Company's  Board of Directors
declared  a special  distribution  of $0.40 per  share.  The  distributions  are
payable on January 15, 1998 to shareholders of record on December 31, 1997.

     In August 1995, the Management Agreement for the mini-warehouse  facilities
was amended to provide  that upon  demand  from PSI made prior to  December  15,
1995,  the Company  agreed to prepay (within 15 days after such demand) up to 12
months of  management  fees  (based on the  management  fees for the  comparable
period  during  the  calendar  year   immediately   preceding  such  prepayment)
discounted  at the rate of 14% per year to  compensate  for  early  payment.  In
November 1995, the Company prepaid,  to PSI, 8 months of 1996 management fees at
a cost of  $102,000.  The amount has been  expensed as  management  fees paid to
affiliate during 1996.

     The  Convertible  Series  B shares  and  Convertible  Series C shares  will

"Conversion")  when  (A) the  sum of (1)  all  cumulative  dividends  and  other
distributions  from  all  sources  paid  with  respect  to the  Series  A shares
(including liquidating distributions,  but not including payments made to redeem
such  stock  other  than in  liquidation)  and (2)  the  cumulative  Partnership
distributions  from all sources with respect to all units equals (B) the product
of $20  multiplied  by the  number of the then  outstanding  "Original  Series A
shares". The term "Original Series A shares" means the Series A shares issued in
the Reorganization. Through December 31, 1997, the Company has made and declared
cumulative cash  distributions of  approximately  $7,169,000 with respect to the
Series A shares. Accordingly, assuming no repurchases or redemptions of Series A
shares after  December  31,  1997,  Conversion  will occur when  $10,046,000  in
additional distributions with respect to the Series A shares have been made.

REIT DISTRIBUTION REQUIREMENT
- -----------------------------

     The  Company  has  elected  and  intends to continue to qualify as 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. As a REIT,
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 the Company's tax return.
Under certain  circumstances,  the Company can rectify a failure to meet the 95%
distribution  test by  making  distributions  after  the  close of a  particular
taxable year and  attributing  those  distributions  to the prior year's taxable
income.  The Company has satisfied the REIT  distribution  requirement for 1995,
1996 and 1997 by attributing  distributions  in 1995, 1996 and 1997 to the prior
year's  taxable  income.  The extent to which the  Company  will be  required to
attribute distributions to the prior year will depend on the Company's operating
results  (taxable  income) and the level of  distributions  as determined by the
Board of Directors.  The basic difference between book income and taxable income
is depreciation  expense.  In 1997, the Company's  Federal tax  depreciation was
$352,000.

     The Company's  Board of Directors has authorized the Company to purchase up
to 300,000 shares of Series A common stock. As of December 31, 1997, the Company
had purchased and retired 184,140 shares of Series A common stock.

YEAR 2000 SYSTEM ISSUES
- -----------------------

     PSI has  completed  an initial  assessment  of its  computer  systems.  The
majority of the computer  programs were  installed or upgraded over the past few
years and are Year 2000 compliant.  Some of the older computer programs utilized
by PSI were written without regard for Year 2000 issues and could cause a system
failure or miscalculations with possible disruption of operations. Each of these
computer  programs and systems has been  evaluated to be upgraded or replaced as
part of PSI's Year 2000 project.

     The cost of the Year 2000 project will be allocated to all  companies  that
use the PSI  computer  systems.  The  cost of the  Year  2000  project  which is
expected to be allocated to the Company is less than $30,000.  This cost will be
expensed as incurred.

     The project is expected to be completed by March 31, 1999 which is prior to
any   anticipated   impact  on  operating   systems.   PSI  believes  that  with
modifications to existing software and, in some instances, the conversion to new
software,  the Year 2000 issue will not pose significant  operational  problems.
However,  if such  modifications are not made, or are not completed timely,  the
Year 2000 issue could have a material impact on the operations of the Company.

     The  costs  of the  project  and the  date on which  PSI  believes  it will
complete the Year 2000  modifications  are based on management's best estimates,
which were derived utilizing numerous assumptions of future events. There can be
no guarantee  that these  estimates  will be achieved and actual  results  could
differ materially from those anticipated.

PROPOSED MERGER
- ---------------

     In  February  1998,  the  Company  and  PSI  agreed,   subject  to  certain
conditions,  to merge. Upon the merger,  each outstanding share of the Company's
common  stock  series A (other  than  shares  held by PSI or by  holders  of the
Company's  common stock  series A ("Series A  Shareholders")  who have  properly
exercised dissenters' rights under California law ("Dissenting Shares")) will be
converted  into the right to receive cash,  PSI common stock or a combination of
the two,  as  follows:  (i) with  respect  to a certain  number of shares of the
Company's  common  stock series A (not to exceed 20% of the  outstanding  common
stock  series A of the Company,  less any  Dissenting  Shares),  upon a Series A
Shareholder's election,  $22.57 in cash, subject to reduction as described below
or (ii)  that  number  (subject  to  rounding)  of shares  of PSI  common  stock
determined by dividing  $22.57,  subject to reduction as described below, by the
average of the per share  closing  prices on the New York Stock  Exchange of PSI
common stock during the 20 consecutive  trading days ending on the fifth trading
day  prior  to  the  special   meeting  of  the  Company's   shareholders.   The
consideration  paid by PSI to the Series A  Shareholders  in the merger  will be
reduced by the amount of cash distributions  required to be paid to the Series A
Shareholders  by the Company  prior to  completion  of the merger  (estimated at
$0.93  per  share)  in  order  to  satisfy  the  Company's   REIT   distribution
requirements ("Required REIT Distributions").  The consideration received by the
Series A  Shareholders  in the merger,  however,  along with any  Required  REIT
Distributions,  will not be less than $22.57 per share of the  Company's  common
stock series A, which amount  represents  the market value of the Company's real
estate  assets at  October  1,  1997  (based on an  independent  appraisal)  and
interest of the Series A  Shareholders  in the  estimated net asset value of its
other assets at April 30,  1998.  Additional  distributions  will be made to the
Series A Shareholders to cause the Company's estimated net asset value allocable
to the Series A  Shareholders  as of the date of the merger to be  substantially
equivalent  to $22.57 per share.  Upon the merger,  each share of the  Company's
common  stock series B and common stock series C (other than shares held by PSI)
would be converted  into the right to receive $10.90 in PSI common stock (valued
as in the case of the Company's  common stock series A) plus (i) any  additional
distributions  equal to the amount by which the  Company's  estimated  net asset
value  allocable to the holders of the Company's  common stock series B and C as
of the date of the  merger  exceeds  $10.90  per  share  and (ii) the  estimated
Required REIT Distributions payable to the holders of the Company's common stock
series B of $0.93 per share. The common stock of the Company held by PSI will be
canceled in the merger. The merger is conditioned on, among other  requirements,
approval by the  Company's  shareholders.  It is  expected  that the merger will
close in the first half of 1998.  PSI is the Company's  mini-warehouse  operator
and owns  24.18% of the total  combined  shares of the  Company's  common  stock
series A, B and C.

                         Report of Independent Auditors


The Board of Directors and Shareholders
Public Storage Properties XX, Inc.


We have audited the accompanying balance sheets of Public Storage Properties XX,
Inc. as of December  31, 1997 and 1996,  and the related  statements  of income,
shareholders'  equity and cash  flows for each of the three  years in the period
ended  December 31, 1997.  Our audits also  included the schedule  listed in the
index  at  item  14(a).   These  financial   statements  and  schedule  are  the
responsibility of the Company's management.  Our responsibility is to express an
opinion on these financial statements and schedule based on our audits.

We  conducted  our  audits  in  accordance  with  generally   accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all material  respects,  the financial position of Public Storage Properties XX,
Inc. at December 31, 1997 and 1996,  and the results of its  operations  and its
cash flows for each of the three years in the period ended December 31, 1997, in
conformity with generally accepted accounting principles.  Also, in our opinion,
the related  financial  statement  schedule,  when considered in relation to the
basic  financial  statements  taken as a whole,  presents fairly in all material
respects the information set forth therein.

                       PUBLIC STORAGE PROPERTIES XX, INC.
                          NOTES TO FINANCIAL STATEMENTS
                                December 31, 1997

1.       DESCRIPTION OF BUSINESS

     Public  Storage  Properties  XX,  Inc.  (the  "Company")  is  a  California
corporation  which has  elected  to qualify as a real  estate  investment  trust
("REIT") for Federal income tax purposes.  The Company succeeded to the business
of Public Storage  Properties XX, Ltd. (the  "Partnership")  in a reorganization
transaction which was effective August 27, 1991 (the "Reorganization").

     The Company owns and operates seven self-storage facilities located in five
states.

     The term of the Company is until all properties  have been sold and, in any
event, not later than December 31, 2038. 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.

2.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Income Taxes:

     The Company has and intends to continue to qualify as a REIT, as defined in
Section 856 of the Internal  Revenue Code (the Code).  As a REIT, the Company is
not taxed on that  portion of its taxable  income  which is  distributed  to its
shareholders  provided that the Company meets the  requirements of the Code. The
Company believes it is in compliance with these  requirements and,  accordingly,
no provision for income taxes has been made.

     Statements of Cash Flows:

     For purposes of financial statement presentation, the Company considers all
highly liquid debt instruments purchased with a maturity of three months or less
to be cash equivalents.

     Real Estate Facilities:

     Cost of land includes  appraisal and legal fees related to acquisition  and
closing costs. Buildings, land improvements and equipment reflect costs incurred
through  December 31, 1997 and 1996 to develop  mini-warehouse  facilities.  The
mini-warehouse facilities provide self-service storage spaces for lease, usually
on a  month-to-month  basis, to the general public.  The buildings and equipment
are depreciated on the straight-line basis over estimated useful lives of 25 and
5 years, respectively.

     In 1995,  the  Financial  Accounting  Standards  Board issued  Statement of
Financial  Accounting  Standards No. 121 ("Statement 121"),  "Accounting for the
Impairment of Long-Lived  Assets and for  Long-Lived  Assets to be Disposed of."
Statement 121 requires  impairment  losses to be recorded on  long-lived  assets
used  in  operations   when   indicators  of  impairment  are  present  and  the
undiscounted  cash flows estimated to be generated by those assets are less than
the assets'  carrying  amount.  Statement 121 also  addresses the accounting for
long-lived  assets  that are  expected to be  disposed  of. The Company  adopted
Statement 121 in 1996 and based on current circumstances,  such adoption did not
have any effect on the financial statements.

2.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

     Real Estate Facilities (continued):

     At December 31, 1997, the basis of real estate facilities  (excluding land)
for Federal income tax purposes (after  adjustment for accumulated  depreciation
of $2,562,000) is $9,344,000.

     Revenue Recognition:

     Property rents are recognized as earned.

     Investment in Affiliate:

     In February  1994,  the Company  purchased  10,000  common shares of Public
Storage, Inc. (PSI), a publicly traded REIT and an affiliate of the Company, for
$148,000.  The Company has designated its portfolio of marketable  securities as
being  available  for sale.  Accordingly,  at December  31,  1997 and 1996,  the
Company has recorded the  marketable  securities  at fair value,  based upon the
closing  quoted price of the  securities at December 31, 1997 and 1996,  and has
recorded a corresponding  unrealized  loss, gain totaling  $16,000 and $120,000,
respectively,   in  shareholders'  equity.  The  Company  recognized  $9,000  in
dividends in 1997, 1996 and 1995.

     Net Income Per Share:

     In 1997, the Financial Accounting Standards Board issued Statement No. 128,
Earnings per Share.  Statement 128 replaced the calculation of primary and fully
diluted  earnings per share with basic and diluted  earnings  per share.  Unlike
primary  earnings  per share,  basic  earnings  per share  excludes any dilutive
effects of convertible securities. Diluted earnings per share is very similar to
the previously reported fully diluted earnings per share. All earnings per share
amounts for all periods  have been  presented  to conform to the  Statement  128
requirements.

     Net income  per share is  presented  on a basic and  diluted  basis.  Basic
earnings per share represents the Series A shareholders' rights to distributions
out of the respective  period's net income,  which is calculated by dividing net
income  after  reduction  for   distributions   to  the  Convertible   Series  B
shareholders  (Series C shareholders are not entitled to cash  distributions) by
the weighted  average  number of  outstanding  Series A shares (Note 4). Diluted
earnings per share assumes  conversion of the Convertible  Series B and Series C
shares into Series A shares.

     Use of Estimates:

     The  preparation of the financial  statements in conformity  with 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.

     Environmental Cost:

     Substantially  all of the Company's  facilities  were acquired prior to the
time that it was customary to conduct environmental investigations in connection
with  property  acquisitions.  During the fourth  quarter of 1995,  the  Company
completed   environmental   assessments   of  its  properties  to  evaluate  the
environmental  condition of, and  potential  environmental  liabilities  of such
properties.  These  assessments  were performed by an independent  environmental
consulting firm. Based on the assessments, the Company expensed $156,000 in 1995
for  known  environmental  remediation  requirements.  Although  there can be no
assurance, the Company is not aware of any environmental contamination of any of
its property sites which  individually  or in the aggregate would be material to
the Company's overall business, financial condition, or results of operations.

                                      F-7

3.       RELATED PARTY TRANSACTIONS

     The Company has a Management  Agreement with Public Storage,  Inc. ("PSI").
Under the terms of the agreement, PSI operates the mini-warehouse facilities for
a fee equal to 6% of the facilities' monthly gross revenue (as defined).

     The Management  Agreement,  as amended in February 1995,  provides that the
agreement will expire in February 2002 provided that in February of each year it
shall be automatically  extended for one year (thereby  maintaining a seven-year
term) unless either party  notifies the other that the  Management  Agreement is
not being extended,  in which case it expires,  on the first  anniversary of its
then scheduled  expiration date. The Management Agreement may also be terminated
by either  party for cause,  but if  terminated  for cause by the  Company,  the
Company  retains the rights to use the service  marks and related  designs until
the then scheduled  expiration  date, if  applicable,  or otherwise a date seven
years after such termination.

     In August 1995, the Management Agreement for the mini-warehouse  facilities
was amended to provide  that upon  demand  from PSI made prior to  December  15,
1995,  the Company  agreed to prepay (within 15 days after such demand) up to 12
months of  management  fees  (based on the  management  fees for the  comparable
period  during  the  calendar  year   immediately   preceding  such  prepayment)
discounted  at the rate of 14% per year to  compensate  for  early  payment.  In
November 1995, the Company prepaid,  to PSI, 8 months of 1996 management fees at
a cost of $102,000. The amount was expensed as management fees paid to affiliate
during 1996.

4.       SHAREHOLDERS' EQUITY

     Series A shares  are  entitled  to all  distributions  of cash from sale or
refinancing  and  participate  ratably with the  Convertible  Series B shares in
distributions  of cash flow from  operations.  The  Convertible  Series C shares
(prior  to  conversion  into  Series  A  shares)  will  not  participate  in any
distributions.

     The  Convertible  Series  B shares  and  Convertible  Series C shares  will
convert  automatically  into  Series A shares on a  share-for-share  basis  (the
"Conversion")  when  (A) the  sum of (1)  all  cumulative  dividends  and  other
distributions  from  all  sources  paid  with  respect  to the  Series  A shares
(including liquidating distributions,  but not including payments made to redeem
such  stock  other  than in  liquidation)  and (2)  the  cumulative  Partnership
distributions  from all sources with respect to all units equals (B) the product
of $20  multiplied  by the  number of the then  outstanding  "Original  Series A
shares". The term "Original Series A shares" means the Series A shares issued in
the Reorganization. Through December 31, 1997, the Company has made and declared
cumulative cash  distributions of  approximately  $7,169,000 with respect to the
Series A shares. Accordingly, assuming no repurchases or redemptions of Series A
shares after  December  31,  1997,  Conversion  will occur when  $10,046,000  in
additional distributions with respect to the Series A shares have been made.

     Assuming  liquidation  of the Company at its net book value at December 31,
1997 and 1996,  each Series of common  shares would  receive the  following as a
liquidating distribution:

                                                    1997              1996
                                                 ------------    ------------
     Series A                                    $13,283,000      $13,626,000

4.       SHAREHOLDERS' EQUITY (CONTINUED)

     The Company's  Board of Directors has authorized the Company to purchase up
to 300,000  shares of the Company's  Series A common  stock.  As of December 31,
1997,  the Company had purchased and retired  184,140  shares of Series A common
stock, of which 10,000 were purchased and retired in 1996.

     For Federal income tax purposes, all distributions declared by the Board of
Directors in 1997, 1996 and 1995 were ordinary income.

5.       NOTE PAYABLE TO BANK

     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 until maturity.  On December
31, 1999, all unpaid principal and accrued interest is due and payable.

     During the first quarter of 1996, the Company  borrowed and repaid $150,000
on its line of credit  facility.  At December 31, 1996, there was no outstanding
balance on the credit facility.

     Under  covenants  of the credit  facility,  the Company is (1)  required to
maintain a ratio of  liabilities  to assets (as defined) for each fiscal quarter
of not more than .3 to 1.0, (2) required to maintain a debt  coverage  ratio (as
defined) for each fiscal quarter of not less than 8 times the debt service,  (3)
required to maintain a fixed charge  coverage ratio (as defined) for each fiscal
quarter  of not less  than 1.0 to 1.0 and (4)  required  to  maintain  a minimum
shareholder's equity (as defined) for each fiscal quarter of $10 million.

6.       PROPOSED MERGER

     In February  1998, the Company and Public  Storage,  Inc.  ("PSI")  agreed,
subject to certain conditions, to merge. Upon the merger, each outstanding share
of the  Company's  common  stock  series A (other  than shares held by PSI or by
holders of the  Company's  common stock series A ("Series A  Shareholders")  who
have properly  exercised  dissenters'  rights under  California law ("Dissenting
Shares"))  will be converted into the right to receive cash, PSI common stock or
a combination  of the two, as follows:  (i) with respect to a certain  number of
shares  of the  Company's  common  stock  series  A (not  to  exceed  20% of the
outstanding common stock series A of the Company,  less any Dissenting  Shares),
upon a Series A Shareholder's election,  $22.57 in cash, subject to reduction as
described  below or (ii) that  number  (subject  to  rounding)  of shares of PSI
common stock  determined by dividing  $22.57,  subject to reduction as described
below,  by the  average  of the per share  closing  prices on the New York Stock
Exchange of PSI common  stock during the 20  consecutive  trading days ending on
the  fifth   trading  day  prior  to  the  special   meeting  of  the  Company's
shareholders.  The consideration paid by PSI to the Series A Shareholders in the
merger will be reduced by the amount of cash  distributions  required to be paid
to the Series A  Shareholders  by the Company  prior to completion of the merger
(estimated  at  $0.93  per  share)  in  order  to  satisfy  the  Company's  REIT
distribution  requirements  ("Required REIT  Distributions").  The consideration
received by the Series A  Shareholders  in the merger,  however,  along with any
Required  REIT  Distributions,  will not be less  than  $22.57  per share of the
Company's common stock series A, which amount represents the market value of the
Company's  real  estate  assets  at  October  1, 1997  (based on an  independent
appraisal) and interest of the Series A Shareholders  in the estimated net asset
value of its other assets at April 30, 1998.  Additional  distributions  will be
made to the Series A  Shareholders  to cause the  Company's  estimated net asset
value  allocable to the Series A Shareholders as of the date of the merger to be
substantially equivalent to $22.57 per share. Upon the merger, each share of the
Company's  common  stock  series B and common  stock series C (other than shares
held by PSI) would be converted  into the right to receive  $10.90 in PSI common
stock  (valued as in the case of the  Company's  common stock series A) plus (i)
any  additional  distributions  equal  to the  amount  by  which  the  Company's
estimated net asset value allocable to the holders of the Company's common stock
series B and C as of the date of the  merger  exceeds  $10.90 per share and (ii)
the  estimated  Required  REIT  Distributions  payable  to  the  holders  of the
Company's  common  stock  series B of $0.93 per share.  The common  stock of the
Company held by PSI will be canceled in the merger.

                                      F-9

6.       PROPOSED MERGER (CONTINUED)

     The merger is  conditioned  on, among other  requirements,  approval by the
Company's  shareholders.  It is expected that the merger will close in the first
half of 1998.  PSI is the Company's  mini-warehouse  operator and owns 24.18% of
the total combined shares of the Company's common stock series A, B and C.

                                                                     Exhibit 2

                      AGREEMENT AND PLAN OF REORGANIZATION


         THIS AGREEMENT AND PLAN OF REORGANIZATION ("Agreement") is entered into
as of this 13th day of  February,  1998,  by and among PUBLIC  STORAGE,  INC., a
California  corporation  ("PSI")  and PUBLIC  STORAGE  PROPERTIES  XX,  INC.,  a
California corporation ("PSP20").

         A. The parties  intend that this Agreement  shall  constitute a Plan of
Reorganization  for purposes of Section  368(a) of the Internal  Revenue Code of
1986, as amended.  The Plan of  Reorganization  provides for the merger of PSP20
with and into PSI in accordance  with the  applicable  provisions of the General
Corporation  Law  of  California  (the  "GCLC")  and  the  Agreement  of  Merger
substantially in the form attached hereto as Exhibit A ("Merger Agreement").

         B. The Boards of Directors  of PSI and PSP20  believe that it is in the
best interests of such  corporations and their respective  shareholders to enter
into and complete this  Agreement and they have approved this  Agreement and the
transactions contemplated hereby.

         NOW, THEREFORE, the parties agree as follows:

         1.     Adoption  of  Plan.   The  parties  hereby  adopt  the  Plan  of
Reorganization hereinafter set forth.

         2.     The Merger.

                2.1 Completion of the Merger.  At the Effective Time (as defined
below), PSP20 will be merged with and into PSI (the "Merger") in accordance with
the terms, conditions and provisions of this Agreement and the Merger Agreement.
The Merger  shall become  effective  at the time at which the Merger  Agreement,
together with the requisite  Officers'  Certificates  of PSI and PSP20 are filed
with  the  California  Secretary  of  State in  accordance  with  the GCLC  (the
"Effective Time"). PSI and PSP20 are sometimes  collectively  referred to herein
as the "Constituent  Corporations" and PSI, as the surviving  corporation of the
Merger, is sometimes referred to herein as the "Surviving Corporation."

                2.2     Effect of the Merger.  At the Effective Time:

                        2.2.1 Constituent  Corporations.  The separate corporate
existence of PSP20 shall cease and the  Surviving  Corporation  shall  thereupon
succeed,  without  other  transfer,  to all the rights and property of PSP20 and
shall be subject to all the debts and liabilities of PSP20 in the same manner as
if the Surviving  Corporation  had itself incurred them; all rights of creditors
and all liens upon the property of each of the Constituent Corporations shall be
preserved  unimpaired,  provided that such liens upon property of PSP20 shall be
limited to the property  affected  thereby  immediately  prior to the  Effective
Time; and any action or proceeding pending by or against PSP20 may be prosecuted
to  judgment,  which  shall bind the  Surviving  Corporation,  or the  Surviving
Corporation may be proceeded against or substituted in its place.

                        2.2.2 Articles and Bylaws. The Articles of Incorporation
and the Bylaws of PSI, as then  amended,  shall  continue to be the  Articles of
Incorporation  and the  Bylaws of the  Surviving  Corporation  until  changed as
provided by law and their respective provisions.

                        2.2.3 Officers and Directors. The officers and directors
of PSI shall  continue as officers and  directors of the  Surviving  Corporation
until  their  successors  are elected  and  qualified  as provided by law and in
accordance  with the  Articles  of  Incorporation  and  Bylaws of the  Surviving
Corporation.

                2.3   Conversion  of  Common  Stock  Series  A.  The  manner  of
converting the  outstanding  shares of Common Stock Series A ($.01 par value) of
PSP20 (the "PSP20  Shares")  into cash and/or  shares of Common  Stock ($.10 par
value) of PSI (the "PSI Shares") shall be as follows:

                        2.3.1 Cash Election.  At the Effective Time,  subject to
Sections  2.6 and 6.8 hereof,  each PSP20 Share as to which a cash  election has
been made in  accordance  with the  provisions of Section 2.5 hereof and has not
been  revoked,  relinquished  or lost  pursuant to Section 2.5 hereof (the "Cash
Election  Shares")  shall be  converted  into and shall  represent  the right to
receive $22.57 in cash (the "Cash Election Price"). As soon as practicable after
the Effective Time, the registered holders of Cash Election Shares shall be paid
the cash to which they are entitled  hereunder in respect of such Cash  Election
Shares.

                        2.3.2 Share Exchange.  At the Effective Time, subject to
Sections  2.4,  2.5,  2.7 and 6.8  hereof,  each PSP20  Share  (other  than Cash
Election  Shares and PSP20  Shares  owned by PSI) shall be  converted  into that
number of PSI Shares equal to, rounded to the nearest  thousandth,  the quotient
(the  "Conversion  Number") derived by dividing $22.57 by the average of the per
share closing  prices on the New York Stock  Exchange,  Inc. (the "NYSE") of PSI
Shares  during the 20  consecutive  trading days ending on the fifth trading day
prior to the  meeting of  shareholders  of PSP20  provided  for in  Section  6.2
hereof.  If, prior to the  Effective  Time,  PSI should split or combine the PSI
Shares,  or pay a stock dividend,  the Conversion  Number will be  appropriately
adjusted to reflect such action.

                2.4 No  Fractional  Shares.  Notwithstanding  any other  term or
provision of this  Agreement,  no fractional PSI Shares and no  certificates  or
script therefor,  or other evidence of ownership thereof,  will be issued in the
Merger.  In lieu of any such fractional  share  interests,  each holder of PSP20
Shares who would  otherwise  be entitled  to such  fractional  share will,  upon
surrender of the certificate representing such PSP20 Shares, receive a whole PSI
Share if such  fractional  share to which such holder would  otherwise have been
entitled  is .5 of an PSI  Share or more,  and such  fractional  share  shall be
disregarded if it represents  less than .5 of an PSI Share;  provided,  however,
that, such fractional share shall not be disregarded if such fractional share to
which such holder would otherwise have been entitled represents .5 of 1% or more
of the total  number of PSI Shares  such  holder is  entitled  to receive in the
Merger.  In such  event,  such holder  shall be paid an amount in cash  (without
interest),  rounded to the nearest $.01,  determined by multiplying  (i) the per
share closing price on the NYSE of the PSI Shares at the Effective  Time by (ii)
the fractional interest.

                2.5 Procedure for Cash  Election.  At the time of the mailing of
the Proxy Statement and Prospectus  provided for in Section 6.5 hereof, PSI will
send to each  holder  of record of PSP20  Shares  at the  record  date for PSP20
meetings of shareholders  referred to in Section 6.2 hereof a cash election form
(the  "Form of  Election")  providing  such  holder  with the option to elect to
receive  the Cash  Election  Price with  respect  to all or any  portion of such
holder's   PSP20  Shares.   Any  such  election  to  receive  the  cash  payment
contemplated  by Section  2.3.1  hereof  shall have been  properly  made only if
American Stock Transfer & Trust Company (the  "Depositary")  shall have received
at its designated  office, by 5:00 p.m., New York time, on the last business day
preceding the day of such meeting of shareholders,  a Form of Election  properly
completed and accompanied by  certificates  for the shares to which such Form of
Election relates (or an appropriate guarantee of delivery in a form and on terms
satisfactory  to  PSI),  as set  forth  in such  Form of  Election.  Any Form of
Election may be revoked by the person submitting the same to the Depositary only
by written notice received by the Depositary  prior to 5:00 p.m., New York time,
on the last business day before the day of the meeting of shareholders  referred
to in Section 6.2 hereof. In addition, all Forms of Election shall automatically
be revoked if the  Depositary is notified in writing by the parties  hereto that
the Merger have been  abandoned.  If a Form of  Election is revoked  pursuant to
this Section 2.5, the  certificate or  certificates or any guarantee of delivery
in respect of the PSP20 Shares to which such Form of Election  relates  shall be
promptly  returned  to the person  submitting  the same to the  Depositary.  The
Depositary  may  determine  whether or not  elections  to receive cash have been
properly   made  or  revoked   pursuant  to  this  Section  2.5,  and  any  such
determination shall be conclusive and binding. If the Depositary determines that
any election to receive  cash was not properly or timely made,  the PSP20 Shares
covered  thereby  shall not be treated  as Cash  Election  Shares,  and shall be
converted in the Merger as provided in Section 2.3.2 hereof. The Depositary may,
with the agreement of PSI and PSP20, establish such procedures, not inconsistent
with this Section  2.5, as may be  necessary  or  desirable  to  implement  this
Section 2.5.

                2.6     Procedure for Proration.

                        2.6.1 No Proration  of PSP20  Shares.  If the  aggregate
number of Cash Election Shares and Dissenting Shares (as defined below) of PSP20
is 20% or less than the number of PSP20 Shares outstanding as of the record date
for the meeting of  shareholders  of PSP20 referred to in Section 6.2, then each
Cash Election  Share of PSP20 shall be converted in the Merger into the right to
receive the Cash Election Price for PSP20 Shares.

                        2.6.2 Proration of PSP20 Shares. If the aggregate number
of Cash Election  Shares and  Dissenting  Shares of PSP20 exceeds 20%, then each
Cash Election  Share of PSP20 shall be converted in the Merger into the right to
receive cash or into PSI Shares as follows:  the number of Cash Election  Shares
of PSP20  owned by a holder of PSP20  Shares  that shall be  converted  into the
right to receive the Cash Election Price for PSP20 Shares shall equal the number
obtained by  multiplying  (i) (A) 20% of  outstanding  PSP20 Shares less (B) the
number of Dissenting Shares (as hereinafter defined) of PSP20, if any, by (ii) a
fraction  of which the  numerator  shall be the number of Cash  Election  Shares
owned by such holder and the denominator  shall be the aggregate  number of Cash
Election  Shares of PSP20.  The balance of such Cash  Election  Shares  shall be
converted  into PSI Shares in  accordance  with the  provisions of Section 2.3.2
hereof.  Notwithstanding the foregoing,  PSI, in its sole discretion,  may allow
Cash  Election  Shares of PSP20 to  receive  the Cash  Election  Price for PSP20
Shares  even if the  aggregate  number of Cash  Election  Shares and  Dissenting
Shares of PSP20 exceeds 20% of the number of PSP20 Shares  outstanding as of the
record date for the meeting of shareholders of PSP20 referred to in Section 6.2,
provided that in no event shall the number of Cash Election Shares exceed 50% of
the outstanding PSP20 Shares.

                2.7  Dissenting  Shares.  PSP20  Shares held by a holder who has
demanded and  perfected  his right to an appraisal of such shares in  accordance
with Section 1300 et seq. of the GCLC and who has not  effectively  withdrawn or
lost his right to appraisal ("Dissenting Shares") shall not be converted into or
represent  the right to receive cash and/or PSI Shares,  but the holder  thereof
shall be entitled  only to such rights as are granted by Section 1300 et seq. of
the GCLC. Each holder of Dissenting  Shares who becomes  entitled to payment for
PSP20 Shares  pursuant to these  provisions  of the GCLC shall  receive  payment
therefor from the Surviving Corporation in accordance  therewith.  If any holder
of PSP20 Shares who demands appraisal in accordance with Section 1300 et seq. of
the  GCLC  shall  effectively   withdraw  with  the  consent  of  the  Surviving
Corporation  or lose  (through  failure to perfect  or  otherwise)  his right to
appraisal with respect to PSP20 Shares, such PSP20 Shares shall automatically be
converted into the right to receive PSI Shares pursuant to Section 2.3.2 hereof.

                2.8 PSI Shares Unaffected.  The Merger shall effect no change in
any of the  outstanding  PSI  Shares  and no  outstanding  PSI  Shares  shall be
converted  or  exchanged  as a  result  of the  Merger,  and no  cash  shall  be
exchangeable, and no securities shall be issuable, with respect thereto.

                2.9  Cancellation  of Shares  Held or Owned by  Parties.  At the
Effective Time, any PSP20 Shares owned by PSI shall be cancelled and retired and
no shares shall be  issuable,  and no cash shall be  exchangeable,  with respect
thereto.

                2.10 Exchange of  Certificates.  After the Effective  Time, each
holder of a certificate  theretofore  evidencing  outstanding PSP20 Shares which
were  converted  into  PSI  Shares  pursuant  hereto,  upon  surrender  of  such
certificate to The First National Bank of Boston (the "Exchange  Agent") or such
other agent or agents as shall be appointed by the Surviving Corporation,  shall
be entitled to receive a certificate representing the number of whole PSI Shares
into  which the PSP20  Shares  theretofore  represented  by the  certificate  so
surrendered  shall have been  converted as provided in Section  2.3.2 hereof and
cash  payment in lieu of  fractional  share  interests,  if any,  as provided in
Section  2.4  hereof.  As soon as  practicable  after the  Effective  Time,  the
Exchange Agent will send a notice and a transmittal form to each holder of PSP20
Shares of record at the  Effective  Time whose stock  shall have been  converted
into PSI Shares, advising such holder of the effectiveness of the Merger and the
procedure for surrendering to the Exchange Agent  certificates  evidencing PSP20
Shares in exchange for certificates evidencing PSI Shares.

                2.11 Status Until Surrendered.  Until surrendered as provided in
Section 2.10 hereof, each outstanding  certificate which, prior to the Effective
Time, represented PSP20 Shares (other than Cash Election Shares and Dissenting

                                       3
<PAGE>

Shares, if any) will be deemed for all corporate  purposes to evidence ownership
of the number of whole PSI Shares into which the PSP20 Shares evidenced  thereby
were converted. However, until such outstanding certificates formerly evidencing
PSP20 Shares are so surrendered, no dividend payable to holders of record of PSI
Shares shall be paid to the holders of such outstanding  certificates in respect
of PSP20 Shares,  but upon surrender of such  certificates by such holders there
shall be paid to such  holders the amount of any  dividends  (without  interest)
theretofore  paid with respect to such whole PSI Shares as of any record date on
or  subsequent  to the  Effective  Time  and the  amount  of any  cash  (without
interest) payable to such holder in lieu of fractional share interests  pursuant
to Section 2.4 hereof.

                2.12 Transfer of Shares.  After the Effective Time,  there shall
be no further  registration of transfers of PSP20 Shares on the records of PSP20
and,  if  certificates  formerly  evidencing  such shares are  presented  to the
Surviving  Corporation,  they shall be cancelled and exchanged for  certificates
evidencing PSI Shares and cash in lieu of fractional  share  interests as herein
provided.

                2.13 Conversion of Common Stock Series B and C. At the Effective
Time,  subject to Section 6.8 hereof,  each share of Common Stock Series B and C
($.01 par value) of PSP20  (other than shares  owned by PSI) shall be  converted
(or deemed to be converted)  into that number of PSI Shares equal to, rounded to
the nearest  thousandth,  the quotient derived by dividing $10.90 by the average
per share  closing  prices on the NYSE of PSI Shares  during the 20  consecutive
trading  days  ending  on  the  fifth  trading  day  prior  to  the  meeting  of
shareholders  of PSP20  provided  for in Section  6.2 hereof.  If,  prior to the
Effective  Time,  PSI should  split or combine  the PSI  Shares,  or pay a stock
dividend,  such conversion number will be appropriately adjusted to reflect such
action. At the Effective Time, any Common Stock Series B and C of PSP20 owned by
PSI shall be cancelled  and retired and no shares shall be issuable with respect
thereto.

         3.     Closing.

                3.1 Time and Place of Closing.  If this Agreement is approved by
the  shareholders  of PSP20,  a meeting  (the  "Closing")  shall  take  place as
promptly as practicable thereafter at which the applicable parties will exchange
certificates  and other  documents as required by this  Agreement.  Such Closing
shall  take place at such time and place as PSI may  designate.  The date of the
Closing shall be referred to as the "Closing Date."

                3.2 Execution and Filing of Merger  Agreement.  At or before the
Closing and after  shareholder  approval of PSP20, the applicable  parties shall
execute and deliver the Merger Agreement,  together with the requisite Officers'

California  with all requisite  corporate  power and authority to own, lease and
operate  its  properties  and to carry on its  business  as and where now owned,
leased,  operated or carried on, as the case may be; and is duly qualified to do
business as a foreign  corporation and is in good standing in each  jurisdiction
in which the  property  owned,  leased or  operated  by it or the  nature of the
business carried on by it requires such  qualification  and where the failure to

to which PSP20 is a party or by which it is bound  calling for or requiring  the
issuance of any of PSP20's capital stock, except that the shares of Common Stock
Series  B and C  are  convertible  into  shares  of  Common  Stock  Series  A in
accordance with PSP20's Articles of Incorporation.

                4.4 Consents and Approvals;  No Violation.  Assuming approval of
the Merger and of this  Agreement  by the  shareholders  of PSP20,  neither  the

of any provision of its Articles of  Incorporation  or Bylaws;  (ii) require any
consent,  waiver,  approval,  authorization  or permit  of,  or  filing  with or

applicable state securities or takeover laws, or (F) where the failure to obtain
such  consent,  approval,  authorization  or permit,  or to make such  filing or
notification, would not in the aggregate have a material adverse effect on PSP20
or  adversely  affect  the  ability  of PSP20  to  consummate  the  transactions
contemplated  hereby;  (iii) result in a violation or breach of, or constitute a
default (or give rise to any right of termination, cancellation or acceleration)
under any of the terms, conditions or provisions of any note, license, mortgage,
agreement or other  instrument or obligation to which PSP20 is a party or any of
its properties or assets may be bound, except for such violations,  breaches and
defaults  which, in the aggregate,  would not have a material  adverse effect on
PSP20 or adversely  affect the ability of PSP20 to consummate  the  transactions
contemplated hereby; or (iv) assuming the consents, approvals, authorizations or
permits and filings or  notifications  referred to in this  Section 4.4 are duly
and timely  obtained  or made,  violate  any order,  writ,  injunction,  decree,
statute,  rule or regulation  applicable  to PSP20 or its  properties or assets,
except for violations  which would not in the aggregate have a material  adverse
effect on PSP20 or  adversely  affect  the  ability of PSP20 to  consummate  the
transactions contemplated hereby.

                4.5   Litigation.   There  is  no   litigation,   proceeding  or
governmental investigation which, individually or in the aggregate, is or may be

and regulations promulgated by the SEC thereunder,  all of which complied in all
material  respects with all applicable  requirements  of the federal  securities
laws and such rules and  regulations  (collectively,  the "PSP20 SEC  Reports").
None of the  PSP20 SEC  Reports,  including  without  limitation  any  financial
statements or schedules included therein, at the time filed contained any untrue
statement of a material  fact or omitted to state a material fact required to be
stated therein or necessary in order to make the statements therein, in light of
the circumstances under which they were made, not misleading.

                4.7 Financial  Statements.  The financial statements included in
the  PSP20  SEC  Reports  complied  as to form  in all  material  respects  with
applicable  accounting  requirements  and the published rules and regulations of

the  business of PSP20 has been carried on only in the ordinary and usual course
and there has not been any material  adverse change in its business,  results of
operations or financial condition, or any damage or destruction in the nature of
a casualty loss,  whether covered by insurance or not, that would materially and
adversely affect its properties, business or results of operations.

such  consent,  approval,  authorization  or permit,  or to make such  filing or
notification,  would not in the aggregate have a material  adverse effect on PSI
or  adversely   affect  the  ability  of  PSI  to  consummate  the  transactions

reports and  documents  with the SEC  required to be filed by it pursuant to the
federal  securities  laws and the rules and  regulations  promulgated by the SEC
thereunder,  all of which complied in all material  respects with all applicable

         6.     Covenants and Agreements.

                6.1 Ordinary  Course.  Except as contemplated by this Agreement,
during the period from the date of this Agreement to the Effective Time, each of
PSI and PSP20 will carry on its business in the ordinary course in substantially
the same manner as heretofore  conducted and use all reasonable  efforts to: (a)
preserve intact its present  business,  organization and goodwill,  (b) maintain
all permits,  licenses and  authorizations  required by applicable laws, and (c)
keep  available  the  services  of  its  present   employees  and  preserve  its
relationships with customers, suppliers, lenders, lessors, governmental entities
and others having business or regulatory  dealings with it. PSP20 will not issue
any capital stock or debt  securities  convertible  into capital stock.  PSI and
PSP20 will  promptly  notify the  others of any event or  occurrence  not in the
ordinary  and usual  course of  business  or which may have a  material  adverse
effect on the properties or financial condition of such party.

                6.2  Meetings  of  Shareholders.  PSP20  will  take  all  action
necessary  in  accordance  with  applicable  law to  convene  a  meeting  of its
shareholders  as promptly as  practicable  to consider and vote upon approval of
this  Agreement,  it being  understood that the principal terms of the Agreement
must be approved by the affirmative vote of a majority of the outstanding shares
of Common Stock Series A, B and C of PSP20,  counted  together as a single class
with the  shares of Common  Stock  Series B and C voted  with the  holders  of a
majority of the unaffiliated shares of Common Stock Series A.

                6.3 Tax  Reporting.  Each of PSI and PSP20  agrees to report the
Merger for federal and state income tax  purposes,  as a  reorganization  of the
type described in Section  368(a)(1)(A) of the Internal Revenue Code of 1986, as
amended.

                6.4 Acquisition Proposals.  PSP20 will not initiate,  solicit or
encourage,  directly or indirectly,  any inquiries or the making of any proposal
with respect to a merger,  consolidation,  share exchange or similar transaction
involving PSP20, or any purchase of all or any significant  portion of either of
their  assets,  or any  equity  interest  in  either  of  them,  other  than the
transactions  contemplated hereby (an "Acquisition Proposal"),  or engage in any
negotiations concerning,  or provide any confidential information or data to, or
have any  discussions  with,  any person  relating to an  Acquisition  Proposal;
provided,  however, that the Board of Directors of PSP20 may furnish or cause to
be  furnished   information  and  may   participate  in  such   discussions  and
negotiations  through its representatives  with persons who have sought the same
if the failure to provide such  information or participate in such  negotiations
and  discussions  might cause the members of the Board of  Directors of PSP20 to
breach their fiduciary duty to the shareholders of PSP20 under applicable law as
advised by counsel.  PSP20 will notify PSI  immediately if any such inquiries or
proposals are received by, any such  information is requested  from, or any such
negotiations  or discussions are sought to be initiated or continued with PSP20,
and will keep PSI informed of the status and terms of any such proposals and any
such negotiations or discussions.

                6.5  Registration  and Proxy  Statements.  PSP20  will  promptly
prepare and file with the SEC a preliminary  proxy  statement in connection with
the vote of  shareholders  of PSP20 with  respect to the  Merger.  PSI will,  as
promptly as practicable,  prepare and file with the SEC a registration statement
on Form S-4 (the "S-4  Registration  Statement"),  containing  a combined  proxy
statement/prospectus,  in connection with the registration  under the Securities
Act of 1933, as amended (the "Securities Act") of the PSI Shares to be issued to
holders of PSP20 Shares in the Merger (such combined proxy statement/prospectus,
together with any amendments thereof or supplements thereto, in each case in the
form or forms to be mailed to the shareholders of PSP20, being herein called the
"Proxy Statement and Prospectus").  PSI and PSP20 will use their best efforts to
have or  cause  the S-4  Registration  Statement  to be  declared  effective  as
promptly  as  practicable,  and also will take any other  action  required to be
taken  under  federal  or state  securities  laws,  and PSP20  will use its best
efforts  to cause  the  Proxy  Statement  and  Prospectus  to be  mailed  to its
shareholders at the earliest  practicable date. PSP20 agrees that if at any time
prior to the  Effective  Time any event with respect to PSP20 should occur which
is required to be described in an  amendment  of, or a supplement  to, the Proxy
Statement and Prospectus or the S-4 Registration Statement, such event shall be

                                       8
<PAGE>

so described,  and such amendment or supplement shall be promptly filed with the
SEC and, as required by law,  disseminated to the shareholders of PSP20 and (ii)
the Proxy  Statement  and  Prospectus  will (with respect to PSP20) comply as to
form in all material  respects with the  requirements of the federal  securities
laws.  PSI agrees that (i) if at any time prior to the Effective  Time any event
with  respect  to PSI should  occur  which is  required  to be  described  in an
amendment of, or a supplement to, the Proxy  Statement and Prospectus or the S-4
Registration Statement,  such event shall be so described, and such amendment or
supplement  shall  be  promptly  filed  with the SEC and,  as  required  by law,
disseminated  to the  shareholders  of PSP20  and (ii) the Proxy  Statement  and
Prospectus will (with respect to PSI) comply as to form in all material respects
with the requirements of the federal securities laws.

                6.6 Best Efforts. Each of PSI and PSP20 shall: (i) promptly make
its respective filings and thereafter make any other required  submissions under
all  applicable  laws with  respect  to the  Merger  and the other  transactions
contemplated hereby; and (ii) use its best efforts to promptly take, or cause to
be  taken,  all other  actions  and do,  or cause to be done,  all other  things
necessary,   proper  or   appropriate  to  consummate  and  make  effective  the
transactions contemplated by this Agreement as soon as practicable.

                6.7  Registration  and Listing of PSI  Shares.  PSI will use its
best efforts to register the PSI Shares under the  applicable  provisions of the
Securities  Act and to cause the PSI Shares to be listed for trading on the NYSE
upon official notice of issuance.

                6.8  Distributions.  PSP20  will not,  at any time  prior to the
Effective  Time,  declare or pay any cash  distribution  on its capital stock or
make any other  distribution of assets to its  shareholders,  except (i) regular
quarterly  dividends  on its Common  Stock at a quarterly  rate not in excess of
$.28 per share, (ii)  distributions to shareholders of record  immediately prior
to the  Effective  Time in an aggregate  amount equal to the amount by which the
estimated  Net  Asset  Value  of  PSP20  (as  defined  below)  allocable  to the
shareholders  as of the Effective  Time exceeds  $22.57 per share in the case of
the PSP20  Shares  and $10.90  per share in the case of the PSP20  Common  Stock
Series B and C and (iii)  pre-Merger  cash  distributions  required  to  satisfy
PSP20's REIT  distribution  requirements (the number of PSI Shares issued in the
Merger and the amount  receivable  upon Cash Elections would be reduced on a pro
rata basis in an aggregate amount equal to such additional  distributions).  For
this  purpose,  the Net Asset  Value of PSP20 is the sum of (a) the fair  market
value of PSP20's real estate  assets as determined by appraisal by The Nicholson
Group,  Ltd. as of October 31, 1997, and (b) the book value of PSP20's  non-real
estate assets as of the date of determination,  and less (c) PSP20's liabilities
as of the date of determination. The determination of book value and liabilities
shall be from PSP20's financial statements prepared in accordance with generally
accepted accounting principles on a basis consistent with prior periods.

         7.     Conditions.

                7.1  Conditions  to Each  Party's  Obligations.  The  respective

requirements  of the HSR Act) shall have been made or obtained  (as the case may
be)  without  material  restrictions,  except  where the  failure to obtain such
consents, approvals, permits and authorizations could not reasonably be expected
to have a material adverse effect on PSI, PSP20.

                        7.1.3 Litigation. No court or governmental or regulatory

         C.  PSI  and  PSP20  have  entered  into  an  Agreement   and  Plan  of
Reorganization dated as of February 13, 1998 (the "Plan"), setting forth certain
representations,  warranties, conditions and agreements pertaining to the Merger
(as defined below).

         D. The Boards of Directors of PSI and PSP20 have  approved the Plan and
this  Agreement  of Merger,  and the  requisite  shareholder  approval  has been
obtained.

         NOW, THEREFORE, the parties agree as follows:

                                    ARTICLE I

                1.1 The Merger. At the Effective Time (as defined below),  PSP20
will be merged with and into PSI (the  "Merger")  and PSI shall be the surviving
corporation.  PSI and PSP20 are sometimes collectively referred to herein as the
"Constituent  Corporations" and PSI, as the surviving corporation of the Merger,
is sometimes referred to herein as the "Surviving Corporation."

                1.2  Effective  Time.  The Merger shall become  effective at the
time at which this Agreement, together with the requisite Officers' Certificates
of PSI and  PSP20,  are  filed  with the  California  Secretary  of  State  (the
"Effective Time").

                1.3 Effect of the Merger. At the Effective Time:

                        (a) The  separate  corporate  existence  of PSP20  shall
cease and the  Surviving  Corporation  shall  thereupon  succeed,  without other
transfer,  to all the rights and  property  of PSP20 and shall be subject to all
the  debts  and  liabilities  of PSP20 in the same  manner  as if the  Surviving
Corporation had itself incurred them; all rights of creditors and all liens upon
the  property  of  each  of the  Constituent  Corporations  shall  be  preserved
unimpaired,  provided that such liens upon property of PSP20 shall be limited to
the property  affected thereby  immediately prior to the Effective Time; and any
action or proceeding  pending by or against PSP20 may be prosecuted to judgment,
which shall bind the Surviving Corporation,  or the Surviving Corporation may be
proceeded against or substituted in its place.

                                      A-1
<PAGE>

                        (b) The Articles of Incorporation and the Bylaws of PSI,
as then  amended,  shall  continue to be the Articles of  Incorporation  and the
Bylaws of the Surviving  Corporation  until changed as provided by law and their
respective provisions.

                        (c) The directors of PSI shall  continue as directors of
the Surviving  Corporation  until their  successors are elected and qualified as
provided by law and in accordance with the Articles of Incorporation  and Bylaws
of the Surviving Corporation.

                                   ARTICLE II

                2.1  Conversion  of PSP20 Shares.  The manner of converting  the
outstanding PSP20 Shares into cash and/or PSI Shares shall be as follows:

                        (a) At the Effective Time, subject to Section 2.6 of the
Plan,  each PSP20 Share as to which a cash  election has been made in accordance
with the  provisions  of  Section  2.5 of the  Plan  and has not  been  revoked,
relinquished  or lost  pursuant to Section  2.5 of the Plan (the "Cash  Election
Shares")  shall be  converted  into and shall  represent  the  right to  receive
$_______ in cash (the "Cash Election  Price").  As soon as practicable after the
Effective Time, the registered holders of Cash Election Shares shall be paid the
cash to which they are  entitled  hereunder  in  respect  of such Cash  Election
Shares.

                        (b) At the Effective Time,  subject to Sections 2.4, 2.5
and 2.7 of the Plan, each PSP20 Share (other than Cash Election Shares and PSP20
Shares owned by PSI) shall be converted into ______ PSI Shares.

                2.2 No  Fractional  Shares.  Notwithstanding  any other  term or
provision  of this  Agreement  or the Plan,  no  fractional  PSI  Shares  and no
certificates or script therefor, or other evidence of ownership thereof, will be
issued in the  Merger.  In lieu of any such  fractional  share  interests,  each
holder of PSP20 Shares who would otherwise be entitled to such fractional  share
will, upon surrender of the certificate  representing such PSP20 Shares, receive
a whole PSI Share if such fractional  share to which such holder would otherwise
have been  entitled  is .5 of an PSI Share or more,  and such  fractional  share
shall be  disregarded if it represents  less than .5 of an PSI Share;  provided,
however, that, such fractional share shall not be disregarded if such fractional
share to which such holder would  otherwise have been entitled  represents .5 of
1% or more of the total  number of PSI Shares such holder is entitled to receive
in the  Merger.  In such  event,  such  holder  shall be paid an  amount in cash
(without interest),  rounded to the nearest $.01,  determined by multiplying (i)
the per share  closing  price on the New York Stock  Exchange,  Inc.  of the PSI
Shares at the Effective Time by (ii) the fractional interest.

                2.3  Dissenting  Shares.  PSP20  Shares held by a holder who has
demanded and  perfected  his right to an appraisal of such shares in  accordance
with  Section 1300 et seq. of the General  Corporation  Law of  California  (the
"GCLC") and who has not  effectively  withdrawn  or lost his right to  appraisal
("Dissenting  Shares")  shall not be converted  into or  represent  the right to
receive cash and/or PSI Shares, but the holder thereof shall be entitled only to
such rights as are granted by Section  1300 et seq. of the GCLC.  Each holder of
Dissenting  Shares who becomes  entitled to payment for PSP20 Shares pursuant to
these  provisions of the GCLC shall receive payment  therefor from the Surviving
Corporation in accordance  therewith.  If any holder of PSP20 Shares who demands
appraisal in accordance with Section 1300 et seq. of the GCLC shall  effectively
withdraw with the consent of the Surviving  Corporation or lose (through failure
to perfect or  otherwise)  his right to appraisal  with respect to PSP20 Shares,
such PSP20 Shares shall automatically be converted into the right to receive PSI
Shares pursuant to Section 2.1(b) hereof.

                2.4 PSI Shares Unaffected.  The Merger shall effect no change in
any of the  outstanding  PSI  Shares  and no  outstanding  PSI  Shares  shall be
converted  or  exchanged  as a  result  of the  Merger,  and no  cash  shall  be
exchangeable and no securities shall be issuable, with respect thereto.

                2.5  Cancellation  of Shares  Held or Owned by  Parties.  At the
Effective Time, any PSP20 Shares owned by PSI shall be cancelled and retired and
no shares shall be  issuable,  and no cash shall be  exchangeable,  with respect
thereto.

                2.6 Exchange of  Certificates.  After the Effective  Time,  each
holder of a certificate  theretofore  evidencing  outstanding PSP20 Shares which
were  converted  into  PSI  Shares  pursuant  hereto,  upon  surrender  of  such
certificate  to First  National  Bank of Boston (the  "Exchange  Agent") or such
other agent or agents as shall be appointed by the Surviving Corporation,  shall
be entitled to receive a certificate representing the number of whole PSI Shares
into  which the PSP20  Shares  theretofore  represented  by the  certificate  so
surrendered  shall have been  converted  and cash payment in lieu of  fractional
share  interests,  if any. As soon as practicable  after the Effective Time, the
Exchange Agent will send a notice and a transmittal form to each holder of PSP20
Shares of record at the  Effective  Time whose stock  shall have been  converted
into PSI Shares, advising such holder of the effectiveness of the Merger and the
procedure for surrendering to the Exchange Agent  certificates  evidencing PSP20
Shares in exchange for certificates evidencing PSI Shares.

                2.7 Status Until  Surrendered.  Until surrendered as provided in
Section 2.6 hereof,  each outstanding  certificate which, prior to the Effective
Time,  represented  PSP20 Shares (other than Cash Election Shares and Dissenting
Shares, if any) will be deemed for all corporate  purposes to evidence ownership
of the number of whole PSI Shares into which the PSP20 Shares evidenced  thereby
were converted. However, until such outstanding certificates formerly evidencing
PSP20 Shares are so surrendered, no dividend payable to holders of record of PSI
Shares shall be paid to the holders of such outstanding  certificates in respect
of PSP20 Shares,  but upon surrender of such  certificates by such holders there
shall be paid to such  holders the amount of any  dividends  (without  interest)
theretofore  paid with respect to such whole PSI Shares as of any record date on
or  subsequent  to the  Effective  Time  and the  amount  of any  cash  (without
interest) payable to such holder in lieu of fractional share interests.

                2.8 Transfer of Shares. After the Effective Time, there shall be
no further  registration  of  transfers  of PSP20 Shares on the records of PSP20
and,  if  certificates  formerly  evidencing  such shares are  presented  to the
Surviving  Corporation,  they shall be cancelled and exchanged for  certificates
evidencing PSI Shares and cash in lieu of fractional  share  interests as herein
provided.

                2.9  Conversion of Common Stock Series B and C. At the Effective
Time, each share of Common Stock Series B (other than shares owned by PSI) shall
be  converted  into  ______ PSI Shares and each share of Common  Stock  Series C
(other than shares owned by PSI) shall be converted into ______ PSI Shares.

                3.3 Counterparts.  This Agreement may be executed in two or more
counterparts,  each of which shall be deemed to be an original, but all of which
shall be considered one and the same agreement.

                3.4 Further Action. If at any time after the Effective Time, the
Surviving Corporation shall determine that any assignments,  transfers, deeds or
other  assurances  are  necessary or desirable to vest,  perfect or confirm,  of
record or  otherwise,  in the  Surviving  Corporation,  title to any property or
rights of  PSP20,  the  officers  of either  Constituent  Corporation  are fully
authorized  in the  name of PSP20 or  otherwise  to  execute  and  deliver  such
documents  and do all things  necessary  and proper to vest,  perfect or confirm
title to such property or rights in the Surviving Corporation.

                3.5  Governing  Law.  This  Agreement  shall be  governed by and
construed in accordance with the laws of the State of California, without giving
effect to the principles of conflict of laws thereof.

                3.6 Abandonment of Merger. The Constituent Corporations have the
power to abandon  the Merger by mutual  written  consent  prior to the filing of
this Agreement with the California Secretary of State.
