(1)  This Registration Statement relates to the proposed acquisition by the
     Registrant of all of the 33,053 units of limited partnership interest
     ("Units") in PS Partners II, Ltd. (the "Partnership") that are not
     currently owned by the Registrant.  The Registrant's acquisition of the
     33,053 Units will be accomplished through a merger of a subsidiary of the
     Registrant into the Partnership and the conversion of the 33,053 Units into
     either cash or common stock of the Registrant.  The book value of the Units
     at September 30, 1998 was $293.70 per Unit.  The maximum number of shares
     of Registrant to be issued in the merger is 1,000,000.  The exact number of
     shares of common stock of the Registrant to be issued in the merger cannot
     be determined at this time.
(2)  Calculated in accordance with rule 457(f)(2) under the Securities Act of
     1933.  $1,942 of the registration fee was previously paid in connection
     with the Partnership's preliminary information statement.

     The Registrant hereby amends this Registration Statement on such date or
dates as may be necessary to delay its effective date until the Registrant shall
file a further amendment which specifically states that this Registration
Statement shall thereafter become effective in accordance with Section 8(a) of
the Securities Act of 1933 or until the Registration Statement shall become
effective on such date as the Commission, acting pursuant to said Section 8(a),
may determine.

                                    March __, 1999

Dear Limited Partner:

     We enclose an information statement, notice of action without a meeting and
prospectus and accompanying cash election form relating to the acquisition by
Public Storage of all of the units of limited partnership interest in the
Partnership not currently owned by Public Storage.  Public Storage, a general
partner of the Partnership, owns 74% of the Partnership units.  Public Storage
is acquiring the units through a merger in which each of your units will be
converted into the right to receive a value of $697 in Public Storage common
stock or, at your election, in cash.

     The Partnership is not asking you to approve the merger or related
amendment to the partnership agreement.  Public Storage, the holder of a
majority of the Partnership units, has executed a written consent approving the
merger and the related amendment to the partnership agreement.

     We are not asking you for a proxy and you are requested not to send us a
proxy.  If you want to receive cash in this transaction, you must make a cash
election by April 29, 1999, as described in the accompanying cash election form.

     If you have any questions, please contact Public Storage's Investor
Services Department at (800) 807-3055, (800) 421-2856 or (818) 244-8080.

                                    Very truly yours,

                                    PUBLIC STORAGE, INC.
                                    General Partner

                                    By:  Harvey Lenkin

                             Public Storage, Inc.
                             PS Partners II, Ltd.

   INFORMATION STATEMENT, NOTICE OF ACTION WITHOUT A MEETING AND PROSPECTUS

     We are furnishing this information statement, notice of action without a
meeting and prospectus to limited partners of PS Partners II, Ltd. (the
"Partnership") in connection with the acquisition by Public Storage, Inc. of all
of the units of limited partnership interest not currently owned by Public
Storage.  Public Storage, a general partner of the Partnership, owns 74% of the
Partnership units.  Public Storage is acquiring the units through a merger in
which each unit not currently owned by Public Storage will be converted into the
right to receive a value of $697 in Public Storage common stock or, at your
election, in cash.

     See "Risk Factors" beginning on page 14 for certain factors that you should
consider, including the following:

     .    Public Storage owns sufficient Partnership units to approve the merger
          without your vote and has done so.

     .    Public Storage and the Partnership have not (1) negotiated the merger
          at arm's length, (2) hired independent persons to negotiate the terms
          of the merger for you or (3) asked any person to make an offer to buy
          the Partnership's assets.

     .    The merger will be taxable for most of you. This means that original
          taxable limited partners who receive either cash or stock will
          recognize a substantial taxable gain.

     .    After the merger, if you do not elect cash you will own an investment
          in an ongoing fully-integrated real estate company instead of an
          interest in a specified portfolio of properties for a fixed period.

     .    If you receive Public Storage common stock, your level of
          distributions will be significantly lower after the merger than the
          amount you received as a limited partner of the Partnership.

     .    The Partnership's assets might be worth more later. Public Storage
          will realize the benefit of any increase in value.

     .    You will not be entitled to dissenters' rights of appraisal under 
                   ---    
          California law in the merger.

     .    Public Storage, which controls the Partnership, has significant
          conflicts of interest in connection with, and will benefit from, the
          merger. In the absence of these conflicts, the terms of the merger may
          have been more favorable to you.

     The Public Storage common stock is traded on the New York Stock Exchange
under the symbol "PSA".  On March __, 1999, the closing price of the Public
Storage common stock on the NYSE was $_______.  There is no active market for
the Partnership units.

     The Partnership is not asking you to approve the merger or related
amendment to the partnership agreement.  Public Storage, the holder of a
majority of the Partnership units, has executed a written consent approving the
merger and the related amendment to the partnership agreement.  We are mailing
this statement on or about April 1, 1999 to limited partners of record at the
close of business on the date of this statement.

                            ______________________

     We are not asking you for a proxy and you are requested not to send us a 
proxy.  If you want to receive cash in this transaction, you must make a cash 
election by April 29, 1999, as described in the accompanying cash election form.

     Neither the Securities and Exchange Commission nor any state's securities
regulator has approved the common stock of Public Storage to be issued under
this Information Statement, Notice of Action Without a Meeting and Prospectus or
determined if this Information Statement, Notice of Action Without a Meeting and
Prospectus is accurate or adequate. Any representation to the contrary is a
criminal offense.

                                    SUMMARY

  The following summary is qualified by the detailed information appearing
elsewhere in this statement, including the appendices.

Overview of Merger

  Public Storage is acquiring the Partnership units Public Storage does not
currently own in the merger under the Agreement and Plan of Reorganization
attached as Exhibit A to this statement as follows:

  .  A wholly owned, second tier subsidiary of Public Storage will be merged
     into the Partnership.

  .  Each Partnership unit (other than units owned by Public Storage) will be
     converted into the right to receive a value of $697 in Public Storage
     common stock or, at your election, in cash. To be effective you must make a
     cash election by April 29, 1999, as described in the accompanying cash
     election form.

  .  The Partnership will make distributions to holders of Partnership units to
     cause the estimated net asset value per unit as of April 30, 1999, the
     Effective Date, to be substantially equivalent to $697.

  .  The market value of the Public Storage common stock issued in the merger
     will be based on the average of the per share closing prices of the Public
     Storage common stock on the NYSE during the 20 consecutive trading days
     ending on the fifth trading day prior to the Effective Date.

  .  Following the merger, Public Storage will own all Partnership units
     (through a wholly owned entity).

  .  Public Storage (through a wholly owned entity) and Wayne Hughes (chief
     executive officer of Public Storage) will retain their general partnership
     interests in the Partnership, and the Partnership will remain in existence.

  See "The Merger - Determination of Amounts to be Received by Limited Partners
in the Merger."  For a description of the terms of the merger, see "The Merger -
The Merger Agreement."

  The Public Storage common stock is listed on the NYSE.  On March __, 1999, the
last full trading day prior to the date of this statement, the reported closing
price per share of Public Storage common stock was $_______.  There is no
established trading market for the Partnership units.  See "Distributions and
Price Range of Public Storage Common Stock" and "Distributions and Market Prices
of Partnership Units."

Summary Risk Factors

  The merger involves certain risks and detriments that you should consider,
including the following:

  .  Vote by Public Storage. Public Storage owns sufficient Partnership units to
     approve the merger without your vote and has done so.

  .  No Arm's Length Negotiation or Independent Representatives. Public Storage
     and the Partnership have not (1) negotiated the merger at arm's length or
     (2) hired independent persons to negotiate the terms of the merger for you.
     If independent persons had been hired, the terms of the merger may have
     been more favorable to you. In addition, Public Storage and the Partnership
     have not asked any person to make an offer to buy the Partnership's assets.
     Other offers could have generated higher prices.

  .  The Merger Is Taxable. The merger will be taxable for most of you. This
     means that original taxable limited partners who receive either cash or
     stock will recognize a substantial taxable gain.

  .  Change from Finite Life to Infinite Life. After the merger, if you do not
     elect cash you will own an investment in an ongoing integrated real estate
     company instead of an interest in a specified portfolio of properties for a
     fixed period. Public Storage

     .  changes its portfolio of properties from time to time without approval
        of shareholders; 

     .  does not plan to sell its assets within a fixed period of time; and
 
     .  is engaged in all aspects of the mini-warehouse industry, including
        property development and management.

                                       3
<PAGE>
 
    If you receive Public Storage common stock in the merger, you will be able
    to liquidate your investment only by selling your shares.  The market value
    of your shares may or may not reflect the full fair market value of Public
    Storage's assets and will fluctuate.

  .  Lower Level of Distributions After the Merger. If you receive Public
     Storage common stock, your level of distributions is expected to be
     significantly lower after the merger than the amount you received as a
     limited partner of the Partnership.

  .  Potential Loss of Future Appreciation. The Partnership's assets may be
     worth more later. Public Storage will realize the benefit of any increase
     in value.

  .  No Dissenters' Rights of Appraisal. You will not be entitled to
                                                  ---
     dissenters' rights of appraisal under California law in the merger.

  .  Conflicts of Interest. Public Storage, which controls the Partnership, has
     conflicts of interest in, and will benefit from, the merger. Public Storage
     has an interest in acquiring Partnership units at the lowest possible
     price, while you have an interest in selling your units at the highest
     possible price. In the absence of these conflicts, the terms of the merger
     may have been more favorable to you.

  .  Control and Influence over Public Storage by the Hughes Family and Public
     Storage Ownership Limitations. The public shareholders of Public Storage
     are substantially limited in their ability to control Public Storage. The
     Hughes family owns approximately 30% of the Public Storage common stock
     (approximately 33% upon conversion of convertible stock). Also, Public
     Storage's charter documents restrict the number of Public Storage shares
     that may be owned by any other person. These ownership factors should
     prevent any takeover of Public Storage not approved by Mr. Hughes.

  .  Uncertainty Regarding Market Price of Public Storage Common Stock. The
     market price of Public Storage common stock may fluctuate after the date
     that the number of shares to be issued to you is determined, but before
     those shares actually are issued. In addition, the market price could
     decrease because of sales of shares issued in this merger and in the merger
     with another REIT described under "Description of Public Storage's
     Properties" and for other reasons.

  .  Tax Risks of Ownership of Public Storage Common Stock Failure to Maintain
     REIT Status. Public Storage is subject to tax risks, including risks as to
     Public Storage's continued qualification for income tax purposes as a "Real
     Estate Investment Trust" or "REIT."

  .  Financing Risks. Public Storage, unlike the Partnership, borrows money ($86
     million at September 30, 1998), which increases the risk of loss.

  .  Possible Future Dilution. The issuance of additional stock by Public
     Storage can reduce the interest of Public Storage shareholders. Public
     Storage has outstanding preferred stock ($869 million at September 30,
     1998) and intends to issue additional preferred stock that prevents payment
     of distributions on Public Storage common stock unless distributions are
     paid quarterly on the preferred stock.

  .  Merger Payments Based on Appraisal Instead of Arm's Length Negotiation. The
     amount you receive in the merger is based on a third party appraisal of the
     Partnership's properties. However, appraisals are opinions as of the date
     specified and are subject to certain assumptions. The true worth or
     realizable value of these properties may be higher or lower than the
     appraised value.

Benefits to Insiders

  The merger involves certain benefits to Public Storage, including the
following:

  .  Own All Partnership Units. As a result of the merger, Public Storage will
     own all of the Partnership units without taxable gain to Public Storage.

  .  Cost Efficiencies. The merger will eliminate almost all Partnership
     administrative expenses, much of which has been borne by Public Storage as
     owner of 74% of the Partnership units.

                                       4
<PAGE>
 
  .  Issue Capital Stock. The merger will enable Public Storage, which is
     seeking to expand its capital base, to issue up to 900,000 shares of common
     stock.

  .  Eliminate Conflicts of Interest. The merger will eliminate the conflicts of
     interest resulting from the competition of the Partnership's properties
     with other mini-warehouses owned by Public Storage.

Potential Benefits of the Merger

  The following are the principal potential benefits of the merger to you:

  (1) If you elect to receive cash, you will liquidate your investment at
approximately 138% of your original investment and at an amount substantially
higher than the prices in the limited secondary transactions involving
Partnership interests.  Also, you will simplify your tax reporting for years
after 1999.

  (2) If you receive Public Storage common stock, the principal potential
benefits to you are:

  .  Ownership Interest in a Diversified Real Estate Company. Because the
     Partnership is not authorized to issue new securities or to reinvest sale
     or financing proceeds, the Partnership is less able to take advantage of
     new real estate investment opportunities. In contrast, Public Storage has a
     substantially larger, more diversified investment portfolio that reduces
     the risks associated with any particular assets or group of assets and
     increases Public Storage's ability to access capital markets for new
     capital investments.

  .  Increased Liquidity. There is no active market for the Partnership units.
     In comparison, Public Storage has approximately 128 million shares of
     common stock listed on the NYSE with an average daily trading volume during
     the 12 months ended September 30, 1998 of approximately 128,000 shares.
     Given Public Storage's market capitalization and trading volume, you are
     likely to enjoy a more active trading market and increased liquidity for
     the Public Storage common stock you receive.

  .  Simplified Tax Reporting. The merger also will simplify your tax reporting
     for years after 1999.

The Partnership

  The Partnership owns (1) six mini-warehouses directly, (2) interests in 27
mini-warehouses (the "Properties") jointly with Public Storage and (3) a 1.9%
interest in PS Business Parks, L.P. ("PSBP") directly and a 0.7% interest in
PSBP jointly with Public Storage.  PSBP owns and operates commercial properties
and is effectively controlled by Public Storage.

  The general partners of the Partnership are Public Storage and Mr. Hughes.
Public Storage manages and operates the Properties under the "Public Storage"
name.  See "Description of Partnership Properties."  There is no active market
for the Partnership units.  See "Distributions and Market Prices of Partnership
Units."

Public Storage

  Public Storage is a fully integrated, self-administered and self-managed REIT
that acquires, develops, owns and operates mini-warehouses.  Public Storage is
the largest owner and operator of mini-warehouses in the United States.  At
September 30, 1998, Public Storage had equity interests (through direct
ownership, as well as general and limited partnership and capital stock
interests) in 1,188 properties located in 38 states, consisting of 1,089 mini-
warehouse facilities and 99 business parks.

  For information on Public Storage's proposed merger with another REIT, you
should read "Description of Public Storage's Properties."

Address and Phone Number

  The principal executive offices of the Partnership and Public Storage are
located at 701 Western Avenue, Glendale, California 91201-2397.  The telephone
number is (818) 244-8080.

Background and Reasons for the Merger

  Public Storage and the Partnership have not negotiated the merger at arm's
length.  Public Storage has structured the merger.  Public Storage controls the
Partnership and has significant conflicts of interest in connection with, and
will benefit from, the merger.  Public Storage and Mr. Hughes, the general
partners of the Partnership, believe that the merger is fair to you.  This is
based in significant part on a third party appraisal of the Properties and on
the opinion of a financial advisor, in which the general partners concur.

                                       5
<PAGE>
 
  The general partners organized the Partnership in 1983 to acquire properties
jointly with Public Storage and alone.  The Partnership is well beyond its
original anticipated term.  The Partnership originally anticipated selling the
Properties and liquidating from five to eight years after acquisition, i.e.,
between 1989 and 1992.

  Public Storage was organized in 1980 and has increased its asset and capital
base substantially since that time.  Much of Public Storage's growth has
resulted from increasing its interest in affiliated entities, like the
Partnership.

  After the merger, Public Storage will own all of the Partnership units, and
the merger will eliminate almost all Partnership administrative expenses,
including the cost of operating as a public entity.

  The consideration you receive in the merger is based on the appraised value of
the Properties as determined by a third party appraiser, Charles R. Wilson &
Associates, Inc. ("Wilson"), as of November 30, 1998.  The general partners
believe that the merger is fair to you.  This is based in significant part on
the Wilson appraisal of the Properties and on the opinion of a financial
advisor, Robert A. Stanger & Co., Inc. ("Stanger"), in which the general
partners concur.

  The general partners considered liquidation and continued ownership by limited
and general partners as alternatives to the merger.  Based on a comparison of
the potential benefits and detriments of the merger with these alternatives, the
general partners concluded that the merger would be more attractive to you than
the alternatives considered.  The general partners did not ask any person to buy
the Partnership's assets.

  In comparing the merger to other alternatives, the general partners noted the
following:

  Liquidation.  The general partners oppose a sale of the Properties because
they believe that the Properties may continue to appreciate in value.  In the
merger, you may either (1) convert your investment into an investment in Public
Storage, which like the Partnership primarily owns mini-warehouses, or (2)
receive cash based on the appraised value of the Properties.  However, if the
Partnership liquidated its assets through asset sales to unaffiliated third
parties, you would not need to rely upon a real estate portfolio appraisal to
estimate the fair market value of the Properties.

  Continued Ownership.  The Partnership is operating profitably.  Continued
ownership by the limited and general partners should provide you with continued
distributions of net operating cash flow and participation in any future
potential appreciation of the Properties and would avoid many of the risks
described under "Risk Factors."  However, continued ownership by the limited and
general partners would fail to secure the potential benefits of the merger to
you described under "The Merger - Potential Benefits of the Merger" or to Public
Storage described under "The Merger - Benefits to Insiders."

Detriments of the Merger

Summary Risk Factors" beginning on page 2.

Determination of Amounts to be Received by Limited Partners in the Merger

  The general partners have determined the amount to be received by you in the
merger based on the estimated net asset value per Partnership unit computed as

 (2) Reflects closing price of shares of PS Business Parks, Inc. on The American
     Stock Exchange, Inc. ("AMEX") as of December 23, 1998 (the PSBP partnership
     interests are exchangeable for those shares on a one unit for one share
     basis).  Assumes a sale of the units at that price and an allocation of the
     proceeds between the Partnership and Public Storage based on their joint
     venture agreement.  See note (7) to table in "The Merger - Determination of
     Amounts to be Received by Limited Partners in the Merger."

     assets offset by the Partnership's interest in prepaid rents, security
     deposits, accounts payable and accrued expenses as of September 30, 1998.
     Also reflects the Partnership's share of a $1.6 million condemnation award.
     See "Description of Partnership's Properties."

 (4) Represents subordinated incentive distributions payable to the general
     partners and distributions attributable to general partners' 1% capital
     interest in the Partnership.

 (5) Based on 128,000 Partnership units.

Federal Income Tax Matters

  The merger will be a taxable event and result in taxable gain or loss to most
of you whether you receive cash or stock.  Taxable limited partners will
recognize gain or loss in an amount equal to the difference between the value of
what they receive in the merger (cash or stock) and their adjusted basis in
their Partnership units.  It has been estimated that an original limited partner
will realize approximately $435 of capital gain per Partnership unit.  The
merger should not be a taxable event to Public Storage.  See "Federal Income Tax
       ------ ---                                                               
Considerations - The Merger."

Fairness Analysis; Opinion of Financial Advisor

  Public Storage and the Partnership have not negotiated the merger at arm's
length.  Public Storage has structured the merger.  Public Storage controls the
Partnership and has significant conflicts of interest in connection with, and
will benefit from, the merger.  The general partners believe that the merger is
fair to you.  This is based in significant part on the Wilson appraisal and the
opinion of a financial advisor, in which the general partners concur.

  The general partners base their conclusion on the following factors:

  .  The Wilson appraisal of the Properties.
  
  .  Stanger delivered a fairness opinion to the Partnership.

  .  Although the merger has been structured by Public Storage, the merger
     provides you with a choice of converting your investment into an investment
     in Public Storage or receiving cash for your investment.

  .  Based on certain significant assumptions, qualifications and limitations,
     the consideration to be received by you compares favorably with other
     alternatives. 

  The general partners believe that the consideration to be received by you in
the merger compares favorably with

  .  the prices of the limited secondary sales of Partnership units;

  .  a range of estimated going-concern values per unit;

  .  an estimated liquidation value per unit; and

  .  the book value per unit.

  The general partners recognize that these comparisons are subject to
significant assumptions, qualifications and limitations.  See "The Merger - 
Comparison of Consideration to be Received in the Merger to Other Alternatives."

  The Partnership engaged Stanger to deliver a written summary of its
determination as to the fairness of the consideration to be received in the
merger, from a financial point of view, to you.  The full text of the opinion is
set forth in Appendix C to this statement and should be read in its entirety.
Subject to the assumptions, qualifications and limitations contained in the
fairness opinion, the fairness opinion concludes that, as of the date of the
fairness opinion, the consideration to be received in the merger is fair to you,
from a financial point of view.  In arriving at its opinion, Stanger considered,
among other things

  .  the independent appraised value of the Properties;

  .  the estimated liquidation value of the Partnership prepared by the
     Partnership, based 

                                       7
<PAGE>
 
     upon a sale of the Partnership's assets to a third party for cash;
 
  .  financial analyses and projections prepared by the general partners
     concerning the going-concern value of the Partnership under its current
     business plan; and

  .  a comparison of limited secondary sales prices of Partnership units with
     the consideration being received by you in the merger. 

The Partnership did not ask Stanger to

  .  select the method of determining the consideration being received by you in
     the merger;

  .  make any recommendation to you whether to select cash or Public Storage
     common stock in the merger; or

  .  express any opinion as to the business decision regarding the merger or its
     alternatives or tax factors resulting from the merger or relating to Public
     Storage's qualification as a REIT.

  Stanger's opinion is based on business, economic, real estate and securities
markets and other conditions as of the date of its analysis.  See "The Merger - 
Fairness Opinion from Stanger."

  The general partners believe that hiring Wilson to appraise the Properties and
Stanger to deliver a fairness opinion helped the general partners fulfill their
duties to you.  However, the Partnership is paying Wilson and Stanger for their
services and Public Storage is expected to pay them for other assignments.  See
"The Merger  Real Estate Portfolio Appraisal by Wilson" and "- Fairness Opinion
from Stanger."

Comparison of Partnership Units with Public Storage Common Stock

     The information below summarizes certain principal differences between the
Partnership units and the Public Storage common stock.  The effect of the merger
if you receive Public Storage common stock is set forth in italics below each
comparison.  For an expanded discussion of these and other comparisons and
effects, see "The Merger  Comparison of Partnership Units with Public Storage
Common Stock."

                                                     performance.  An increase in Public Storage's FFO will not

                                                     Marketability and Distributions."
</TABLE>

    If you receive Public Storage common stock in the merger, you will change
your investment from "finite-life" to "infinite life" and realize the value of
your investment only by selling your Public Storage common stock.  If Public
Storage issues additional securities, including securities that would have
priority over Public Storage common stock as to cash flow, distributions and
liquidation proceeds, it will dilute the interest of Public Storage
shareholders. Public Storage intends to issue additional securities under a
currently effective registration statement. See "Risk Factors - Uncertainty
Regarding Market Price of Public Storage Common Stock" and "- Financing Risks -
Dilution and Subordination."

    Public Storage has outstanding debt and reinvests proceeds from borrowings.
Incurring debt increases the risk of loss of investment. Public Storage does not
plan to finance the Properties.

</TABLE>

    Given Public Storage's control of all Partnership voting decisions, both
Public Storage and the Partnership can enter into transactions with affiliates
without the need for approval of either the public shareholders or public
limited partners. In the case of Public Storage, however, these transactions
require approval of Public Storage's independent directors.

</TABLE>

    Because Public Storage owns substantially more property interests in more
states than the Partnership, the operations of a single property have less
effect on Public Storage's results of operations than in the case of the
Partnership. Also, it would be more difficult to liquidate Public Storage than
the Partnership within a reasonable period of time.

                                                     Public Storage has issued, and may in the future issue,
                                                     securities that have priority over Public Storage common stock as
                                                     to cash flow, distributions and liquidation proceeds.
</TABLE>

    The Partnership pays distributions to limited partners from cash available
 for distribution.  Tax laws require Public Storage to distribute at least 95%
 of its ordinary REIT taxable income in order to maintain its qualification as a
 REIT.  Since Public Storage distributes less than its cash available for
 distribution (recently distributing amounts approximately equal to its taxable
 income), it is able to retain funds for additional investment and debt
 reduction.

    If you receive Public Storage common stock in the merger, the market for
 your investment will be broader and more active than the market for Partnership
 units.  Distributions on Public Storage common stock are lower than the
 distributions on the Partnership units.  Distributions on Public Storage common
 stock also are subject to priority of preferred stock.

        Additional Issuances of Securities and Anti-Takeover Provisions

The partnership agreement does not provide for       Subject to the rules of the NYSE and applicable provisions of
the issuance of additional Partnership units.        California law, Public Storage can issue authorized capital stock
                                                     without shareholder approval.
</TABLE>

    Both the Partnership and Public Storage can deter attempts to obtain control
in transactions not approved by management.  In the case of the Partnership,
Public Storage owns a majority of the Partnership units.  In the case of Public
Storage, the Hughes family effectively controls Public Storage and Public
Storage has the flexibility to issue capital stock, including senior securities
with special voting rights and priority over Public Storage common stock.

- ---------------
(1) Net income per common share is computed in accordance with Statement of
    Financial Accounting Standard No. 128 (SFAS 128) -  "Earnings per Share" and
    is presented on the diluted basis using the weighted average shares of
    Public Storage common stock outstanding-diluted.  The diluted net income per
    common share is computed using the weighted average common shares
    outstanding (adjusted for stock options).  The class B common stock is not
    included in the determination of net income per common share because all
    contingencies required for the conversion to Public Storage common stock
    have not been satisfied as of September 30, 1998.  In addition, the
    inclusion of Public Storage's convertible preferred stock in the
    determination of net income has been determined to be anti-dilutive.

(2) For federal income tax purposes all distributions on the Public Storage
    common stock are from ordinary income.  All distributions for generally
    accepted accounting principles ("GAAP") were from investment income.

(3) Book value per share computed based on the number of shares of Public
    Storage common stock and Public Storage class B common stock outstanding.

(4) Limited partners' per unit data is based on the weighted average number of
    Partnership units (128,000) outstanding during the year.

(5) Condemnation proceeds and a portion of the operating cash reserve of the
    Partnership (estimated at $31.32 per Partnership unit) were distributed in
    1995 and a portion of the operating cash reserve of the Partnership
    (estimated at $4.90 per unit) was distributed in 1997.

(6) Presents pro forma amounts of Public Storage per equivalent Partnership
    unit.  Net income, cash distributions and book value data are calculated by
    multiplying Public Storage's historical results (before impact of the
    merger, which is not expected to have a material impact on Public Storage's
    per share amounts) by an assumed exchange ratio of 25.12 (the Partnership's
    merger value of $697 divided by an assumed issue price of Public Storage
    common stock of $27.75).

Relationships


  The following charts show the relationships among Hughes, Public Storage and
the Partnership both before and after the merger (assuming maximum cash
elections).  As reflected in the charts below, Mr. Hughes, Public Storage's
chairman of the board and chief executive officer, effectively controls Public
Storage.  Public Storage and Mr. Hughes are the general partners of the
Partnership.  Public Storage and the Partnership jointly own the Properties,
which are managed by Public Storage.

RISK FACTORS

  The merger involves certain risks and detriments that you should consider,
including the following:

Vote by Public Storage

  Public Storage, as owner of 74% of the Partnership units, owns sufficient
units to approve the merger without your vote and has voted its units in favor
of the merger.

No Arm's Length Negotiation or Independent Representatives

  Public Storage and the Partnership have not (1) negotiated the merger at arm's
length or (2) hired independent persons to negotiate the terms of the merger for
you.  If independent persons had been hired, the terms of the merger may have
been more favorable to you.  In addition, Public Storage and the Partnership
have not asked any person to make an offer to buy the Partnership's assets.
Other offers could have generated higher prices.

The Merger Is Taxable

  The merger will be taxable to most of you.  This means that original taxable
limited partners who receive either cash or stock will recognize a substantial
taxable gain.

Change from Finite Life to Infinite Life

  The Partnership is a limited partnership organized to hold interests in
properties for a fixed period.  In contrast, Public Storage, which is engaged in
all aspects of the mini-warehouse industry, including property development and
management, intends to operate for an indefinite period.  Therefore, if you
receive Public Storage common stock in the merger, you will be able to liquidate
your investment only by selling your shares on the NYSE or in private
transactions.  The market value of Public Storage common stock may or may not
reflect the full fair market value of Public Storage's assets and will
fluctuate.

Lower Level of Distributions After the Merger

  If you receive Public Storage common stock in the merger, your level of
distributions will be significantly lower after the merger than the amount you
received as a limited partner of the Partnership.

Potential Loss of Future Appreciation

  The Partnership's assets may increase in value and might be able to be sold
for higher prices at a later date.  Public Storage will realize the benefit of
any increase in value.

No Dissenters' Rights of Appraisal

  Under California law, you will not be entitled to dissenters' rights of
                                 ---                                     
appraisal in connection with the merger.

Conflicts of Interest

  Relationships Among Parties.  Because of the relationships among Public
Storage, the Partnership and Hughes, there are significant conflicts of interest
in connection with the merger.  Public Storage and Hughes are the general
partners of the Partnership, and Public Storage owns 74% of the Partnership
units.  See "Summary -  Relationships."

  Structuring of Merger by Insiders.  Public Storage initiated and structured
the merger.  Public Storage and the Partnership did not negotiate the merger at
arm's length.  Public Storage has an interest in acquiring the Partnership units
at the lowest possible price, while you have an interest in selling your units
at the highest possible price.  Public Storage and the Partnership did not hire
independent persons to negotiate the terms of the merger for you.  If
independent persons had been hired, the terms of the merger might have been more
favorable to you.

  Benefits to Insiders.  The merger involves certain benefits to Public Storage,
including the following:

  .  Ownership of All Partnership Units. As a result of the merger, Public
     Storage will own all of the Partnership units without taxable gain to
     Public Storage.

  .  Cost Efficiencies. The merger will eliminate almost all Partnership
     administrative expenses, much of which has been borne by Public Storage as
     owner of 74% of the Partnership units.

  .  Issuance of Capital Stock.  The merger will enable Public Storage, which is
     seeking to 

                                       14
<PAGE>
 
     expand its capital base, to issue up to 900,000 shares of common stock.

  .  Elimination of Conflicts of Interest. The merger will eliminate the
     conflicts of interest resulting from the public limited partners' ownership
     of a minority interest in the Partnership. The principal conflicts involve
     the competition of the Properties with other mini-warehouses owned by
     Public Storage.

Control and Influence over Public Storage by the Hughes Family and Public
Storage Ownership Limitations

  Public shareholders of Public Storage are substantially limited in their
ability to control Public Storage.  The Hughes family owns approximately 30% of
the outstanding shares of Public Storage common stock (approximately 33% upon
conversion of the Public Storage class B common stock).  Consequently, the
Hughes family effectively controls matters submitted to a vote of Public Storage
shareholders, including electing directors, amending Public Storage's Articles
of Incorporation, dissolving and approving other extraordinary transactions,
such as a takeover attempt.  Also, the Public Storage Articles of Incorporation
and Bylaws restrict the beneficial ownership of Public Storage securities.
Unless Public Storage's board of directors waives these limitations, no Public
Storage shareholder may own more than (A) 2.0% of the outstanding shares of all
common stock of Public Storage or (B) 9.9% of the outstanding shares of each
class or series of preferred or equity stock of Public Storage.  The Public
Storage Articles of Incorporation and Bylaws in effect provide, however, that
the Hughes family may continue to own the shares of Public Storage common stock
held at the time of a 1995 reorganization.  These limitations are designed, to
the extent possible, to avoid a concentration of ownership that might jeopardize
the ability of Public Storage to qualify as a REIT. See "- Tax Risks - Increased
Risk of Violation of Ownership Requirements." These limitations, however, also
make a change of control significantly more difficult (if not impossible) even
if it would be favorable to the interests of the public shareholders of Public
Storage. These provisions will prevent future takeover attempts not approved by
the Public Storage Board of Directors even if a majority of the public
shareholders of Public Storage deem it to be in their best interests because
they would receive a premium for their shares over the shares' then market value
or for other reasons. See "Description of Public Storage Capital Stock -
Ownership Limitations."

Uncertainty Regarding Market Price of Public Storage Common Stock

  If you receive Public Storage common stock in the merger, the number of shares
is based on the average market price of Public Storage common stock for the 20
consecutive trading days ending on the fifth trading day prior to the Effective
Date.  Since the market price of Public Storage common stock fluctuates, the
market value of Public Storage common stock that you may receive in the merger
may decrease after the date that the number of shares is determined, but before
those shares actually are issued.  In addition, because of possible increased
selling activity following issuance of shares in this merger and in the merger
with another REIT described under "Description of Public Storage's Properties"
and other factors, such as changes in interest rates and market conditions, the
market value of Public Storage common stock that you may receive in the merger
may decrease following the merger.

Tax Risks of Ownership of Public Storage Common Stock - Failure to Maintain REIT
Status

  If you receive Public Storage common stock in the merger, you will be subject
to the risk that Public Storage may not qualify as a REIT.  As a REIT, Public
Storage must distribute at least 95% of its REIT taxable income to its
shareholders (which include not only holders of Public Storage common stock but
also holders of preferred stock).  Failure to pay full dividends on the
preferred stock could jeopardize Public Storage's qualification as a REIT.  See
"Federal Income Tax Considerations - General Tax Treatment of Public Storage,"
and "- Consequences of the PSMI Merger on Public Storage's Qualification as a
REIT."

  For any taxable year that Public Storage fails to qualify as a REIT and the
relief provisions do not apply, Public Storage would be taxed at the regular
corporate rates on all of its taxable income, whether or not it makes any
distributions to its shareholders.  Those taxes would reduce the amount of cash
available to Public Storage for distribution to its shareholders or for
reinvestment.  As a result, failure of Public Storage to qualify during any
taxable year as a REIT could have a material adverse effect upon Public Storage
and its shareholders.  Furthermore, unless certain relief provisions apply,
Public Storage would not be eligible to elect REIT status again until the fifth
taxable year that begins after the first year for which Public Storage fails to
qualify.

                                       15
<PAGE>
 
Financing Risks

  Risk of Leverage.  In making real estate investments, Public Storage, unlike
the Partnership, borrows money, which increases the risk of loss.  At September
30, 1998, Public Storage's debt of $86 million was approximately 2.5% of its
total assets.

  Dilution and Subordination.  Issuing additional securities can dilute the
interest of Public Storage shareholders in Public Storage, including persons who
receive shares in the merger.

  Public Storage intends to issue additional securities under a currently
effective registration statement.  Issuing additional stock will dilute the
interest of Public Storage shareholders.  See "Description of Public Storage
Capital Stock" for a discussion of the terms of the preferred stock, common
stock and equity stock.

  If Public Storage is liquidated, holders of the preferred stock will be
entitled to receive, before any distribution of assets to holders of Public
Storage common stock, liquidating distributions (an aggregate of approximately
$869 million with respect to preferred stock outstanding at September 30, 1998),
plus any accrued and unpaid dividends.  Holders of preferred stock are entitled
to receive, when declared by the Public Storage board of directors, cash
dividends (an aggregate of approximately $76.2 million per year with respect to
preferred stock outstanding at September 30, 1998), in preference to holders of
Public Storage common stock.

Merger Payments Based on Appraisal Instead of Arm's Length Negotiation

  The payments you receive in the merger is based in significant part on a third
party appraised value of the Properties.  However, appraisals are opinions as of
the date specified and are subject to certain assumptions and may not represent
the true worth or realizable value of the Properties.  There can be no assurance
that if the Properties were sold, they would be sold at the appraised values;
the sales prices might be higher or lower.

Operating Risks

  Value of Investment Reduced by General Risks of Real Estate Ownership.  Like
the Partnership, Public Storage is subject to the risks generally incident to
the ownership of real estate-related assets, including

  .  lack of demand for rental spaces or units in a locale;

  .  changes in general economic or local conditions, changes in supply of or
     demand for similar or competing facilities in an area; 

  .  the impact of environmental protection laws;

  .  changes in interest rates and availability of permanent mortgage funds
     which may render the sale or financing of a property difficult or
     unattractive; and

  .  changes in tax, real estate and zoning laws.

  Significant Competition Among Mini-Warehouses.  Like the Partnership, most of
Public Storage's properties are mini-warehouses.  Competition in the market
areas in which many of their properties are located is significant and has
affected the occupancy levels, rental rates and operating expenses of certain of
their properties.  Any increase in availability of funds for investment in real
estate may accelerate competition.  Recent increases in development of mini-
warehouses are expected to further intensify competition among mini-warehouse
operators in certain market areas in which Public Storage operates.

  Risk of Environmental Liabilities.  Under various federal, state and local
environmental laws, an owner or operator of real estate interests may have to
clean up spills or other releases of hazardous or toxic substances on or from a
property.  Certain environmental laws impose liability whether or not the owner
knew of, or was responsible for, the presence of the hazardous or toxic
substances.  In some cases, liability may not be limited to the value of the
property.  The presence of such substances, or the failure to properly remediate
any resulting contamination, also may adversely affect the owner's or operator's
ability to sell, lease or operate its property or to borrow using its property
as collateral.

  Public Storage has conducted preliminary environmental assessments of most of
its properties (and intends to conduct such assessments in connection with
property acquisitions) to evaluate the environmental condition of, and potential
environmental liabilities associated with, such properties.  Such assessments
generally consist of an investigation of environmental conditions at the subject
property (not including soil or groundwater sampling or analysis), as well as a
review of available information regarding the site and publicly available data
regarding conditions at other sites in the vicinity.  

                                       16
<PAGE>
 
In connection with these recent property assessments, Public Storage's
operations and recent property acquisitions, Public Storage has become aware
that prior operations or activities at certain facilities or from nearby
locations have or may have resulted in contamination to the soil and/or
groundwater at such facilities. In this regard, certain such facilities are or
may be the subject of federal or state environmental investigations or remedial
actions. Public Storage has obtained, with respect to recent acquisitions and
intends to obtain with respect to pending or future acquisitions, appropriate
purchase price adjustments or indemnifications that it believes are sufficient
to cover any such potential liabilities. Although there can be no assurance,
based on the recent preliminary environmental assessments, Public Storage
believes it has funds available to cover any liability (estimated at $4 million)
from environmental contamination or potential contamination and Public Storage
is not aware of any environmental contamination of its facilities material to
its overall business, financial condition or results of operation.

  Tenant Reinsurance.  A corporation owned by the Hughes family reinsures
policies insuring against losses to goods stored by tenants in the mini-
warehouses operated by Public Storage.  Public Storage believes that the
availability of insurance reduces its potential liability to tenants for losses
to their goods from theft or destruction.  This corporation will continue to
receive the premiums and bear the risks associated with the insurance.  Public
Storage has a right of first refusal to acquire the stock or assets of this
corporation if the Hughes family or the corporation agree to sell them, but
Public Storage has no interest in its operations and no right to acquire the
stock or assets of the corporation unless the Hughes family decides to sell.  If
the reinsurance business were owned directly by Public Storage, the insurance
premiums would be nonqualifying income to Public Storage.  In the absence of a
change in tax laws, REIT requirements would likely preclude Public Storage from
exercising its right of first refusal to acquire the stock of the reinsurance
corporation.

  Canadian Operations.  The Hughes family owns and operates mini-warehouses in
Canada.  Public Storage has a right of first refusal to acquire the stock or
assets of the corporation engaged in these operations if the Hughes family or
the corporation agree to sell them.  However, Public Storage has no interest in
the operations of this corporation and no right to acquire this stock or assets
unless the Hughes family decides to sell.

  Merchandise and Portable Self-Storage Companies.  At almost all of Public
Storage's mini-warehouses, PS Orangeco, Inc. (the "Lock/Box Company") offers for
sale to the general public, including mini-warehouse tenants, a variety of items
such as locks and boxes to assist in the moving and storage of goods.  Because
the revenues received from the sale of these items would be nonqualifying income
to Public Storage, Public Storage owns the nonvoting preferred stock of the
Lock/Box Company (representing 95% of the equity).  The Hughes family, which
owns the voting common stock of the Lock/Box Company (representing 5% of the
equity), controls the operations of the Lock/Box Company.

  Public Storage organized Public Storage Pickup & Delivery ("PSPUD") in 1996 to
operate a portable self-storage business.  Public Storage owns substantially all
of the economic interest of PSPUD.  Since PSPUD will operate profitably only if
it can succeed in the relatively new field of portable self-storage, there can
be no assurance as to its profitability.  As a start-up enterprise, PSPUD
incurred operating losses of $31,700,000 in 1997 and $25,200,000 during the
first nine months of 1998.  See "Federal Income Tax Considerations - General Tax
Treatment of Public Storage" concerning the treatment of income from and
investment in PSPUD for purposes of the REIT income and asset tests.

  Liabilities with Respect to Acquired General Partner Interests.  When Public
Storage succeeded to substantially all of the properties and operations of a
predecessor in a 1995 reorganization, Public Storage became subject to all of
the predecessor's potential pre-reorganization liabilities as general partner of
various limited partnerships.  Public Storage will also have general partner
liability for post-merger activities of these partnerships, as it does for other
partnerships for which it is a general partner.  Subject to certain limitations,
Mr. Hughes agreed to indemnify Public Storage for pre-merger activities and
escrowed shares of Public Storage convertible stock to support this
indemnification.

                              BENEFITS TO INSIDERS

     THE MERGER INVOLVES CERTAIN BENEFITS TO PUBLIC STORAGE, INCLUDING THE
FOLLOWING:

     .  Ownership of All Partnership Units. As a result of the merger, Public
        Storage will own all of the Partnership units without taxable gain to
        Public Storage.

     .  Cost Efficiencies. The merger will eliminate almost all Partnership
        administrative expenses, much of which has been borne by Public Storage
        as owner of 74% of the Partnership units.

     .  Issuance of Capital Stock. The merger will enable Public Storage, which
        is seeking to expand its capital base, to issue up to 900,000 shares of
        common stock.

     .  Elimination of Conflicts of Interest. The merger will eliminate the
        conflicts of interest resulting from the public limited partners'
        ownership of a minority interest in the Partnership. The principal
        conflicts involve the competition of the Properties with other mini-
        warehouses owned by Public Storage.

                                  THE MERGER
General

     The acquisition of the Partnership units not currently owned by Public
Storage will be accomplished in the merger as follows:

     .    A wholly-owned, second tier subsidiary of Public Storage will be
          merged into the Partnership.

     .    Each Partnership unit (other than units owned by Public Storage) will
          be converted into the right to receive a value of $697 in Public
          Storage common stock or, at the election of a limited partner, in
          cash. To be effective a cash election must be made by April 29, 1999,
          in accordance with the accompanying cash election form.

     .    Distributions will be made to holders of Partnership units to cause
          the estimated net asset value per Partnership unit as of the Effective
          Date to be substantially equivalent to $697. In computing the
          estimated net asset value per unit as of the Effective Date, the PSBP
          partnership interests will be valued at the average of the per share
          closing price on the AMEX of the shares of PS Business Parks, Inc.
          during the 20 consecutive trading days ending on the fifth trading day
          prior to the Effective Date.

     .    For purposes of the merger, the market value of the Public Storage
          common stock will be the average of the per share closing prices on
          the NYSE of the Public Storage common stock during the 20 consecutive
          trading days ending on the fifth trading day prior to the Effective
          Date.

     .    Following the merger, Public Storage (through a wholly owned entity)
          will own all Partnership units.

     .    Public Storage (through a wholly owned entity) and Hughes retain their
          general partnership interests in the Partnership, and the Partnership
          remains in existence.

     It is estimated that the aggregate consideration (cash or Public Storage
common stock or a combination of the two) to be paid by Public Storage to
acquire in the merger the Partnership units owned by the public limited partners
will be approximately $23,285,000.  See "- Determination of Amounts to be
Received by Limited Partners in the Merger" and "- Costs of the Merger."

Background and Reasons for the Merger

     The merger has not been negotiated at arm's length.  The merger has been
structured by Public Storage, which controls the Partnership and has significant
conflicts of interest in connection with, and will benefit from, the merger.
Based in significant part on a third party appraisal of the Properties and on
the opinion of a financial advisor, in which they concur, Public Storage and
Hughes, the general partners of the Partnership, believe that the merger is fair
to the public limited partners.

     The Partnership was organized in 1983 and raised $64 million in a public
offering.  All of the proceeds from the offering have been invested to acquire
properties jointly with Public Storage.  A predecessor of Public Storage
sponsored the Partnership.

     As indicated in the original prospectus, the Partnership originally
anticipated selling the Properties and liquidating from five to eight years
after acquisition, i.e., between 1989 and 1992.  By 1990, significant changes
had taken place in the financial and real estate markets affecting the timing of
any proposed sale of the Properties, including:  (i) the increased construction
of mini-warehouses from 1984 to 1988, which had increased competition, (ii) the
general deterioration of the real estate market (resulting from a variety of
factors, including the 1986 changes in tax laws), which had significantly
affected property values and decreased real estate sales activities, (iii) the
reduced sources of real estate financing (resulting from a variety of factors,
including adverse developments in the savings and loan industry) and (iv) the
glut in the real estate market caused by overbuilding and sales of properties

                                       19
<PAGE>
 
acquired by financial institutions.  Accordingly, the Properties were not
marketed during the originally anticipated liquidation period.

     In view of the events affecting the timing of the sale of the Properties,
PSMI concluded that the limited partners of the Partnership, as well as the
limited partners of other partnerships sponsored by PSMI, should be provided
with a more efficient method of realizing the value of their investment than the
secondary market for limited partnership interests.  Accordingly, Public Storage
purchased Partnership units from those limited partners who desired to sell,
including through tender offers in 1994 and 1996.  As a result of these
purchases, public limited partners now own only 26% of the units with the
balance owned by Public Storage.  Since the Partnership is beyond its original
anticipated term and the public limited partners own only a minority of the
units, the general partners have decided to eliminate through the merger the
ongoing costs of a public structure and the conflicts of interest resulting from
the public limited partners' ownership of a minority interest in the
Partnership.  The principal conflicts involve the competition of the Properties
with other mini-warehouses owned by Public Storage.

     Public Storage, which was organized in 1980, has from time to time taken
actions to increase its asset and capital base and increase diversification,
such as by increasing its interest in affiliated entities, like the Partnership.
Public Storage's interest in the Partnership include (i) Public Storage and the
Partnership jointly own the Properties, (ii) Public Storage (through a wholly-
owned entity) and Hughes are general partners of the Partnership, (iii) Public
Storage (through a wholly owned entity) owns 74% of the Partnership units and
(iv) the Properties are managed by Public Storage.  As a result of the merger,
Public Storage will own all of the Partnership units and almost all Partnership
administrative expenses will be eliminated.

Fairness Analysis

     The merger has not been negotiated at arm's length.  The merger has been
structured by Public Storage, which controls the Partnership and has significant
conflicts of interest in connection with, and will benefit from, the merger.
However, based in significant part on a third party appraisal of the Properties
and on the opinion of Stanger, in which they concur, the general partners
believe that the merger is fair to public limited partners.

     The general partners based their conclusions on the following factors:  (i)
the consideration to be received by the limited partners in the merger is based
on the appraised value of the Properties as determined by Wilson; (ii) the
Partnership has received a fairness opinion from Stanger relating to the
consideration to be received by public limited partners; (iii) although the
merger has been structured by Public Storage, the merger provides public limited
partners with a choice of converting their investment into an investment in
Public Storage or receiving cash for their investment; and (iv) based on certain
significant assumptions, qualifications and limitations, the consideration to be
received by public limited partners compares favorably with other alternatives.

     The general partners believe that the engagement of Wilson and Stanger to
provide the portfolio appraisal and the fairness opinion, respectively, assisted
the general partners in the fulfillment of their duties to public limited
partners, notwithstanding that these parties received fees in connection with
their engagements by the Partnership and in connection with other engagements
and may receive fees in the future.  See "- Real Estate Portfolio Appraisal by
Wilson" and "- Fairness Opinion from Stanger."

Alternatives to the Merger

     The general partners considered liquidation and continued ownership by the
limited and general partners as alternatives to the merger.  In order to
determine whether the merger or one of its alternatives would be more
advantageous to public limited partners, the general partners compared the
potential benefits and detriments of the merger with the potential benefits and
detriments of the alternatives.

     Liquidation

          Benefits of Liquidation.  An alternative to the merger would be to
liquidate the Partnership's assets, distribute the net liquidation proceeds to
the partners and thereafter dissolve the Partnership.  Through such liquidation,
the Partnership would provide for a final disposition of its partners' interests
in the Partnership.  Limited partners would receive cash liquidation proceeds
(as they will if they make cash elections).  If the Partnership 

                                       20
<PAGE>
 
liquidated its assets through asset sales to unaffiliated third parties, limited
partners would not need to rely upon a real estate portfolio appraisal of the
fair market value of the Partnership.  The Partnership would be valued through
arm's length negotiations between the Partnership and prospective purchasers.

          Disadvantages of Liquidation.  Over the last several years, the
performance of the Properties has improved as described under "- Continued
Ownership of the Partnership  Benefits of Continued Ownership."  The general
partners believe that the improvement may continue.  The merger provides limited
partners with the opportunity either to convert their investment in the
Partnership into an investment in Public Storage, which like the Partnership
primarily owns mini-warehouses, or to receive cash based on the appraised value
of the Properties.  In contrast to the merger, the Partnership would also be
expected to incur certain costs in a liquidation.

          Limited partners should recognize that appraisals are opinions as of
the date specified and are subject to certain assumptions and may not represent
the true worth or realizable value of the Properties.  There can be no assurance
that if the Properties were sold, they would be sold at the appraised value; the
sales price might be higher or lower than the appraised value.

     Continued Ownership of the Partnership

          Benefits of Continued Ownership.  Another alternative to the merger
would be to continue the Partnership in accordance with its existing business
plan, with the Partnership continuing to be owned by the limited and general
partners.  The Partnership is operating profitably.

          There has been improvement in the mini-warehouse markets.  As the pace
of new mini-warehouse development has slowed from the peak levels of 1984-88,
there has been a corresponding improvement in the financial performance of
existing properties.  This improvement is evidenced by the performance of the
Properties.  From 1995 to the first nine months of fiscal 1998, weighted average
occupancy for the mini-warehouses remained constant at about 90%, and realized
annual rents per occupied square foot for the mini-warehouses increased from an
average of $7.08 to $7.92.  Despite significant recent increases in the
development of new mini-warehouses, the general partners believe that the
financial performance of the Properties may continue to improve, although not
necessarily at the rate of improvement experienced in prior years.  Should such
improvements continue, the value of the Properties could be expected to
increase.  See "Description of Partnership Properties."

          A number of advantages could be expected to arise from the continued
ownership of the Partnership by the limited and general partners.  Limited
partners would continue to receive regular quarterly distributions of net cash
flow arising from operations and the sale or refinancing of the Partnership's
assets.  Given the currently improving market conditions for mini-warehouses,
the general partners believe that the level of these distributions to limited
partners may increase.  Continued ownership of the Partnership by the general
and limited partners affords limited partners with the opportunity to
participate in any future appreciation in the Partnership's assets.  In
addition, this decision, if elected, would mean that there would be no change in
the nature of the investment of limited partners.  This option avoids whatever
disadvantages might be deemed inherent in the merger.  See "Risk Factors" for
discussion of various risks associated with the merger.

          Disadvantages of Continued Ownership.  Not only is the Partnership
well beyond its anticipated term, but continued ownership of the Partnership by
the limited and general partners fails to secure the benefits that the limited
and general partners expect to result from the merger.  The benefits to limited
partners are highlighted under "- Potential Benefits of the Merger," and the
benefits to the general partners are highlighted under "Benefits to Insiders."
The merger affords limited partners increased liquidity.  In addition, because
the Partnership is not authorized to issue new securities or to reinvest sale or
financing proceeds, the Partnership is less able to take advantage of new real
estate investment opportunities.  In contrast, Public Storage has a
substantially larger, more diversified, investment portfolio that reduces the
risks associated with any particular assets or group of assets and increases
Public Storage's ability to access capital markets for new capital investments.

Determination of Amounts to be Received by Limited Partners in the Merger

     In connection with the merger, limited partners will receive a value of
$697 per Partnership unit in cash or Public Storage common stock.  The general
partners have determined this amount based on the estimated net asset value per
unit computed as follows:

     (1)  Reflects appraised value of the Properties determined by Wilson, as of
          November 30, 1998.  Assumes proceeds from a deemed sale of the
          Properties at the appraised value are allocated between the
          Partnership and Public Storage based on their joint venture agreement.

     (2)  Reflects closing price of shares of PS Business Parks, Inc. on the
          AMEX as of December 23, 1998 (the PSBP partnership interests are
          exchangeable for those shares on a one unit for one share basis).
          Assumes proceeds from a deemed sale of the units at that price are
          allocated between the Partnership and Public Storage based on their
          joint venture agreement. See note (7) below.

     (3)  Includes the Partnership's interest in cash and other non-real estate
          assets offset by the Partnership's interest in prepaid rents, security
          deposits, accounts payable and accrued expenses as of September 30,
          1998.  Also reflects the Partnership's share of a $1.6 million
          condemnation award.  See "Description of Partnership's Properties."

     (4)  Represents subordinated incentive distributions payable to the general
          partners under the partnership agreement and distributions
          attributable to general partners' 1% capital interest in the
          Partnership.

     (5)  Based on 128,000 Partnership units.

     (6)  Upon completion of the merger, each Partnership unit would be
          converted into Public Storage common stock with a value of $697 or, at
          the election of a limited partner, in cash.  The number of shares of
          Public Storage common stock to be issued in the merger will be
          determined by dividing $697 by the average of the closing prices of
          Public Storage common stock during the 20 consecutive trading days
          ending on the fifth trading day prior to the Effective Date.  The
          market price of Public Storage common stock may fluctuate after the
          date that the number of shares to be issued to limited partners in the
          merger is determined and before those shares actually are issued.

     (7)  Distributions will be made to limited partners to cause the estimated
          net asset value per Partnership unit as of the Effective Date to be
          substantially equivalent to $697 per unit.  In computing the estimated
          net asset value per unit as of the Effective Date, the PSBP
          partnership interests will be valued at the average of the per share
          closing price on the AMEX of the shares of PS Business Parks, Inc.
          during the 20 consecutive trading days ending on the fifth trading day
          prior to the Effective Date.

     (8)  Original purchase price of a Partnership unit was $500.

Potential Benefits of the Merger

     The general partners believe that the following are the principal potential
benefits to limited partners:

     (i)  Limited partners who elect to receive cash will have fully liquidated
their investment at approximately 138% of their original investment and at an
amount substantially higher than the prices in the limited secondary
transactions.  Also, they will have simplified their tax reporting for years
after 1998.

     (ii) For limited partners who receive Public Storage common stock, the
principal potential benefits are:
   
     .    Ownership Interest in a Diversified Real Estate Company. Because the
          Partnership is not authorized to issue new securities or to reinvest
          sale or financing proceeds, the Partnership is less able to take
          advantage of new real estate investment opportunities. In contrast,
          Public Storage has a substantially larger, more diversified,
          investment portfolio that reduces the risks associated with any
          particular assets or group of assets and increases Public Storage's
          ability to access capital markets for new capital investments.

     .    Increased Liquidity.  There is no active market for the Partnership
          units. In comparison, Public Storage has approximately 128 million
          shares of Public Storage common stock listed on the NYSE with an
          average daily trading volume during the 12 months ended September 30,
          1998 of approximately 128,000 shares. Given Public Storage's market
          capitalization and trading volume, limited partners who receive Public
          Storage common stock are likely to enjoy a more active trading market
          and increased liquidity for the Public Storage securities they
          receive.

     .    Simplified Tax Reporting.  The merger also will simplify tax reporting
          for years after 1998 for limited partners who receive Public Storage
          common stock. Public Storage shareholders will receive Form 1099-DIV
          to report their dividends from Public Storage. Form 1099-DIV is
          substantially easier to understand than the Schedule K-1 prepared for
          the reporting of the financial results of the Partnership.

Detriments of the Merger

     For a discussion of certain risks and detriments of the merger, see "Risk
Factors" beginning on page 14.

Fairness Analysis

     Conclusions.  Based upon an analysis of the merger, the general partners
have concluded that (i) the terms of the merger are fair to public limited
partners and (ii) after comparing the potential benefits and detriments of the
merger with alternatives, the merger is more advantageous to public limited
partners than such alternatives.

     Although the general partners reasonably believe the terms of the merger
are fair to public limited partners, the general partners have significant
conflicts of interest with respect to the merger.  The merger has been initiated
and structured by Public Storage, one of the general partners.  See "Summary
Relationships" and "Risk Factors  Conflicts of Interest."

     Material Factors Underlying Conclusions of General Partners.  The following
is a discussion of the material factors underlying the conclusions of the
general partners.  The general partners have not quantified the relative
importance of these factors.

     1.   Consideration Offered.  The general partners believe that (i) basing
the consideration to be paid to public limited partners in the merger on the
value of the Partnership's assets is reasonable and consistent with the
partnership agreement, (ii) the Partnership's net asset value represents a fair
estimate of the value of its assets, net of liabilities, and constitutes a
reasonable basis for determining the consideration to be received by public
limited partners, (iii) the allocation of the appraised value of the Properties
between the Partnership and Public Storage is fair because it reflects the
amount each would receive upon the Partnership's liquidation under the joint
venture agreement and (iv) the allocation of the Partnership's net asset value
between the limited and general partners is fair because it reflects the amount
they would receive upon the Partnership's liquidation under the partnership
agreement.  

                                       23
<PAGE>
 
There was no negotiation regarding the basis for determining the consideration
to be paid to public limited partners in the merger.  See "-Background and
Reasons for the Merger."

     2.   Choice as to Form of Consideration.  The merger provides public
limited partners with the choice of either (A) converting their investment into
an investment in Public Storage, which generally owns the same type of
properties as the Partnership and which has acquired, and is expected to
continue to acquire, additional properties or (B) receiving in cash the amounts
they would receive if the Properties were sold at their appraised values and the
Partnership's interest in PSBP were sold at its market value and the Partnership
were liquidated (without any reduction for commissions and other sales
expenses).

     3.   Independent Portfolio Appraisal and Fairness Opinion.  The conclusions
of the general partners are based in significant part upon the portfolio
appraisal prepared by Wilson and Stanger's fairness opinion.  The general
partners attributed significant weight to these items, which they believe
support their position, and do not know of any factors that are reasonably
likely to detract from the conclusions in Wilson's portfolio appraisal and
Stanger's fairness opinion.  The general partners believe that the engagement of
Wilson and Stanger to provide the portfolio appraisal and the fairness opinion,
respectively, assisted the general partners in the fulfillment of their duties
to public limited partners, notwithstanding that these parties received fees in
connection with their engagements by the Partnership and in connection with
other engagements by Public Storage and its affiliates and may receive fees in
the future.  See "- Real Estate Portfolio Appraisal by Wilson" and "- Fairness
Opinion from Stanger."

     4.   Comparison of Payments to be Received in the Merger to Other
Alternatives.  The payment to be received in the merger of $697 per Partnership
unit generally compares favorably with (A) the prices at which limited secondary
sales of units have been effectuated, (B) a range of estimated going-concern
value per unit ($625 to $650, (C) an estimated liquidation value per unit ($674)
and (D) the book value per unit as of September 30, 1998 ($294).  The general
partners recognize that this comparison is subject to significant assumptions,
qualifications and limitations.  See "- Comparison of Consideration to be
Received in the Merger to Other Alternatives."

     5.   Lower Level of Distributions to Limited Partners After the Merger. The
level of distributions to limited partners who receive Public Storage common
stock in the merger will be significantly lower after the merger than before.

     6.   Conflicts of Interest.  The merger has been initiated and structured
by Public Storage, one of the general partners. Independent representatives were
not engaged to negotiate these arrangements on behalf of public limited
partners, and the terms of the merger are not the result of arm's length
negotiations.

     The general partners do not believe that the absence of independent
representatives to negotiate the merger undermines the fairness of the merger.
Based upon the use of an independent appraisal firm and the Stanger fairness
opinion, the general partners considered that the engagement of such independent
representatives was not necessary or cost effective.

Comparison of Consideration to be Received in the Merger to Other Alternatives

     General.  The general partners compared the consideration to be received in
the merger, i.e., a value of $697 per Partnership unit to:  (i) the prices at
which limited secondary sales have been effectuated; (ii) estimates of the value
of the Partnership on a liquidation basis assuming that its assets were sold at
their appraised fair market value and the net proceeds distributed between the
joint venture partners in accordance with the joint venture agreement and
between the limited and general partners in accordance with the partnership
agreement; and (iii) estimates of the value of the Partnership on a going-
concern basis assuming that it were to continue as a stand-alone entity and its
assets sold at the end of a five-year holding period.  Due to the uncertainty in
establishing these values, the Partnership established a range of estimated
values for certain of the alternatives, representing a high and low estimated
value for the potential consideration.  Since the value of the consideration for
alternatives to the merger is dependent upon varying market conditions, no
assurance can be given that the range of estimated values indicated establishes
the highest or lowest possible values.  However, the general partners believe
that analyzing the alternatives in terms of ranges of estimated value, based on
currently available market data and, where appropriate, reasonable assumptions
made in good faith, establishes a reasonable framework for comparing
alternatives.

                                       24
<PAGE>
 
     The results of these comparative analyses are summarized in the following
tables.  Limited partners should bear in mind that the estimated values assigned
to the alternate forms of consideration are based on a variety of assumptions
that have been made by the Partnership.  These assumptions relate, among other
things, to:  projections as to the future income, expenses, cash flow and other
significant financial matters of the Partnership; the capitalization rates that
will be used by prospective buyers when the Partnership's assets are liquidated;
and, appropriate discount rates to apply to expected cash flows in computing the
present value of the cash flows that may be received with respect to Partnership
units.  In addition, these estimates are based upon certain information
available to the Partnership at the time the estimates were computed, and no
assurance can be given that the same conditions analyzed by them in arriving at
the estimates of value would exist at the time of the merger.  The assumptions
used have been determined by the Partnership in good faith, and, where
appropriate, are based upon current and historical information regarding the
Partnership and current real estate markets, and have been highlighted below to
the extent critical to the conclusions of the general partners.

     No assurance can be given that such consideration would be realized through
any of the designated alternatives, and limited partners should carefully
consider the following discussions to understand the assumptions, qualifications
and limitations inherent in the presented valuations.  The estimated values
presented in the following table are "forward-looking statements" within the
meaning of the Private Securities Litigation Reform Act of 1995.  These
estimated values are based upon certain assumptions that relate, among other
things, to (i) the price of Public Storage common stock and common stock of PS
Business Parks, Inc. as of the date of the merger being the same as during the
20 trading days ending on the fifth trading day prior to the Effective Date,
(ii) projections as to the future revenues, expenses, cash flow and other
significant financial matters of the Partnership, (iii) the capitalization rates
that will be used by prospective buyers when the Partnership's assets are
liquidated, (iv) selling costs, (v) appropriate discount rates to apply to
expected cash flows in computing the present value of the cash flows and (vi)
the manner of sale of the Properties.  Actual results may vary from those set
forth below based on numerous factors, including interest rate fluctuations, tax
law changes, supply and demand for mini-warehouses, the manner in which the
properties are sold and changes in availability of capital to finance
acquisitions of mini-warehouses.

(1)  Based on the Partnership's net asset value consisting of the independently
     appraised market value of the Properties as of November 30, 1998, the
     closing price of PS Business Parks, Inc. on the AMEX on December 23, 1998
     and estimated book value of its other net assets as of September 30, 1998.
     The market price of Public Storage common stock may fluctuate following
     establishment of the number of shares to be issued to limited partners in
     the merger and prior to issuance and could decrease as a result of
     increased selling activity following issuance of the shares in the merger
     and other factors.  See "- Determination of Amounts to be Received by
     Limited Partners in the Merger."

(2)  There is no active market for the Partnership units. Based on the
     information available to the Partnership, the prices at which limited
     secondary sales have been effectuated ranged from $189 to $530 per unit
     from January 1, 1996 through September 30, 1998. Included in this price
     range are sales to Public Storage. See "Distributions and Market Prices of
     Partnership Units."

     liquidation.  See "- Liquidation Values."

     Limited Secondary Market Prices of Units.  There is no active market for
the Partnership units.  Based on the information available to the Partnership,
the prices at which limited secondary sales have been effectuated ranged 

                                       25
<PAGE>
 
from $189 to $530 per unit from January 1, 1996 through September 30, 1998.
Included in this price range are sales to Public Storage. See "Distributions and
Market Prices of Partnership Units."

     Going-Concern Value.  The Partnership has estimated the going-concern value
of the Partnership by analyzing projected cash flows and distributions assuming
that the Partnership was operated as an independent stand-alone entity and its
assets sold in a liquidation of the Partnership after a five-year holding
period.  The Partnership assumed sale of the Properties at the terminal value
projected by capitalizing the net operating income in year six at a
capitalization rate of 9.8%, which was equal to the midpoint of (a) the
effective implied capitalization rate (at appraised values) for the Properties
based upon reported property operations (before non-recurring expenses and after
certain property tax adjustments) during the 12 months ended September 30, 1998
and (b) the capitalization rate used in the residual value component of the
discounted cash flow analysis.  Under both scenarios, the Partnership assumed
that the Partnership's interest in PSBP was sold at an FFO multiple of 11.1.
Real estate selling costs were assumed to be incurred at the same percentage of
sale proceeds (4.3%) as incurred in the liquidation alternative.  Distribution
and sale proceeds per Partnership unit were discounted in the projections at
rates ranging from 12% to 13% (11.5% to 12.5% with respect to the interest in
PSBP).

     Both scenarios of the going-concern analysis assume that the Properties are
sold in a single transaction at the expiration of the holding period.  Should
the assets be liquidated over time, even at prices equal to those projected,
distributions to limited partners out of the Partnership's cash flow from
operations might be reduced because relatively fixed costs, such as general and
administrative expenses, are not proportionately reduced with the liquidation of
assets.  However, for simplification purposes, the sales are assumed to occur
concurrently.

     The estimated value of the Partnership on a going-concern basis is not
intended to reflect the distributions payable to limited partners if its assets
were to be sold at their current fair market value.

     Liquidation Values.  Since one of the alternatives available to the general
partners is to proceed with a liquidation of the Partnership and a distribution
of the net liquidation proceeds between the joint venture partners and, within
the Partnership, to the limited partners and the general partners in accordance
with the partnership agreement, the Partnership has estimated the liquidation
value of the Partnership assuming that the Properties are sold at their fair
market value, based upon the Wilson real estate portfolio appraisal.  This
alternative assumes that the Partnership's interest in PSBP is sold at the
December 23, 1998 trading price (less a commission of $.06 per unit), the
Partnership incurs real estate selling costs at the time of liquidation (state
and local transfer taxes, real estate commissions of 3% of sales proceeds and
legal and other closing costs) of $4,675,000, and the remaining net liquidation
proceeds are distributed between the joint venture partners in accordance with
the joint venture agreement and between the limited and general partners in
accordance with the partnership agreement, according priority to limited
partners.

     The liquidation analysis assumes that the Properties are sold in a single
transaction at their appraised value.  Should the assets be liquidated over
time, even at prices equal to those projected, distributions to limited partners
from cash flow from operations might be reduced because the Partnership's
relatively fixed costs, such as general and administrative expenses, are not
proportionately reduced with the liquidation of assets.  However, for
simplification purposes, the sales of the Properties are assumed to occur
concurrently.

     Applying these procedures, the Partnership arrived at the liquidation value
set forth in the table.  The real estate portfolio appraisal sets forth, subject
to the specified assumptions, limitations and qualifications, Wilson's
professional opinion as to the market value of the Properties as of November 30,
1998.  While the portfolio appraisal is not necessarily indicative of the price
at which the assets would sell, market value generally seeks to estimate the
price at which the Properties would sell if disposed of in an arm's length
transaction between a willing buyer and a willing seller, each having access to
relevant information regarding the historical revenues and expenses.  The real
estate portfolio appraisal assumes that the Properties are disposed of in an
orderly manner and are not sold in forced or distressed sales where sellers
might be expected to dispose of their interests at substantial discounts to
their actual fair market value.  See "- Real Estate Portfolio Appraisal by
Wilson."

     Distribution Comparison.  The general partners have considered the
potential impact of the merger upon distributions that would be made to limited
partners who exchange their Partnership units for Public Storage common stock.
Based on a market price of Public Storage common stock of $27.75 and the current
regular quarterly 

                                       26
<PAGE>
 
distribution rate for Public Storage ($.22 per share) and the Partnership ($8.36
per unit), limited partners would receive approximately $2.83 (33.9%) less in
regular quarterly distributions per Partnership unit after the merger from
Public Storage than before the merger from the Partnership and approximately
$.19 less per unit in regular quarterly distributions for each $1.00 (3.6%)
increase in the market price of Public Storage common stock above $27.75. These
estimates are based upon the actual distributions made by Public Storage and the
Partnership (not upon the amounts that might have been distributed by them based
upon their cash flow from operations).

     In evaluating this estimate, limited partners should bear in mind that this
comparison does not reflect the tax that a limited partner will have to pay in
connection with the merger.  The merger will be a taxable event for the public
limited partners resulting in the recognition of gain to most taxable public
limited partners who receive either cash or Public Storage common stock.  In
evaluating this estimate, limited partners should also bear in mind that a
number of factors affect the level of distributions.  These factors include the
distributable income generated by operations, the principal and interest
payments on debt, if any, capital expenditure levels (in excess of normal
expenditures for ongoing maintenance and repairs) and the corporate policy with
respect to cash distributions.  A comparison of the current distribution levels
of Public Storage with those of the Partnership does not show how the merger
might affect a limited partner's distribution level over a number of years.

Real Estate Portfolio Appraisal by Wilson

     Wilson was engaged by the Partnership to appraise the Properties and has
delivered a written report of its analysis, based upon the review, analysis,
scope and limitations described therein, as to the fair market value of the
Properties as of November 30, 1998.  The Partnership selected Wilson to provide
the appraisal because of its experience and reputation in appraising mini-
warehouses, including its appraisal of other properties managed by Public
Storage.  The consideration to be paid by Public Storage to the limited partners
in the merger is based on the appraisal.  The appraisal, which contains a
description of the assumptions and qualifications made, matters considered and
limitations on the review and analysis, is set forth as Appendix B and should be
read in its entirety.  Certain of the material assumptions, qualifications and
limitations to the appraisal are described below.

     Experience of Wilson.  Wilson was formed by Charles R. Wilson in 1976, who
has specialized in the appraisal of mini-warehouses and commercial facilities
since 1972.  Wilson has conducted real estate appraisals on a variety of
property types and uses throughout the United States for owners, banks and
thrift organizations, insurance companies and other financial institutions.
Wilson has appraised over 500 mini-warehouses and commercial properties during
the 12 months ended September 1998.

     Summary of Methodology.  At the request of the Partnership, Wilson
evaluated the Properties.  In valuing the Properties, Wilson considered the
applicability of all three commonly recognized approaches to value:  the cost
approach, the income approach and the sales comparison approach.  The type and
age of a property, market conditions and the quantity and quality of data affect
the applicability of each approach in a specific appraisal situation.  Wilson
did not consider the cost approach to be applicable to the Properties.

     The income approach estimates a property's capacity to produce income
through an analysis of the rental market, operating expenses and net income.
Net income may then be processed into a value estimate through either (or a
combination) of two methods:  direct capitalization or yield capitalization,
i.e., a discounted cash flow analysis.

     The sales comparison approach is based upon the principle of substitution,
i.e., that an informed purchaser would pay no more for a property than the cost
of acquiring an existing property with the same utility.  The sales comparison
approach establishes what typical investors in the marketplace are willing to
pay for comparable properties.

     The cost approach is based on the estimated market value of the site as if
vacant plus the depreciated replacement cost of the existing improvements.  The
cost approach was not considered appropriate in the case of the Properties since
(a) today's investors do not rely upon the cost approach in making investment
decisions and (b) the necessity of estimating total accrued depreciation in
buildings of the type and age of the Properties diminishes the validity of this
approach.

                                       27
<PAGE>
 
     While the appraisal was prepared for all of the Properties, Wilson analyzed
the individual Properties by (a) reviewing each Property's previous four years'
operating statements, (b) reviewing information submitted to Wilson by on-site
managers which included competitive rental and occupancy surveys, subject
facility descriptions, area trends and other factors, which were verified by
Wilson through physical inspections, telephone calls and other sources and (c)
developing information from a variety of sources about market conditions for
each individual property that included population, employment and housing trends
within the market.

     To determine any significant differences in quality among the Properties,
Wilson considered such variables as property income growth patterns and
potential, quality of location and construction, tenant appeal, property
appearance, security and potential competition.

     Wilson also interviewed management personnel responsible for the Properties
to discuss competitive conditions, area economic trends affecting the
properties, historical operating revenues and expenses, lease terms and
occupancy rates in competitive facilities.  These interviews included
ascertaining information on items of deferred maintenance, planned capital
improvements and other factors affecting the physical condition of the
properties.  Representatives of Wilson or persons engaged by them performed site
inspections on the Properties between September 1998 and December 1998.

     Wilson then estimated the value of each Property relying primarily upon the
income approach.  Indicated values were developed using a yield capitalization
technique applying overall capitalization rates derived directly from the
marketplace.  To define the occupancy and rental rates and expense escalators to
be used in developing cash flow projections, Wilson reviewed the acquisition
criteria and projection parameters in use in the marketplace by major mini-
warehouse investors, owners and operators, appraisers and financing sources.  In
addition, Wilson reviewed other published information concerning acquisition
criteria in use by property investors through the third quarter of 1998.
Further, Wilson interviewed various sources in local markets to identify sales
of mini-warehouses within the past 24 months in order to derive certain
valuation indicators.  Sources for data concerning such transactions included
local appraisers, property owners, real estate brokers and others.  Wilson also
reviewed information compiled by management identifying sales and acquisitions
of mini-warehouses.

     In applying a discounted cash flow analysis, projections of cash flow from
each property (assuming no indebtedness) were developed for a 10-year period
ending in the year 2008 with a terminal residual value computed at the end of
year 10.  The first year's scheduled gross income was estimated taking into
consideration each property's current rent structure and the rental rates of
competitive facilities.  Also included in the income estimate were trends in
ancillary income from late fees and rental concessions.  Wilson then made an
analysis of each subject's occupancy history, took into consideration the
occupancy level of competitive facilities and estimated a stabilized occupancy
level for each of the Properties.

     Estimated expenses were based upon each Property's actual operating
history.  The projected expenses were tested for reasonableness based upon a
comparison of the operating expense ratios to market norms.  Expenses were
deducted from effective gross income to derive a net operating income for each
property.  Consideration was given to and adjustment made to reflect capital
expenditures and replacement reserves.  Income and expense growth rates were
based on projection parameters currently being used by property investors as
well as upon local, regional and historical trends.

     For the Properties, Wilson used a growth rate of between 3% and 3.5% for
income and expenses except for real estate taxes in California for which Wilson
used 2.0%.  Wilson then used terminal capitalization rates of between 10.25% and
10.5% to capitalize each Property's 11th year net income into a residual value
at the end of a 10-year holding period, assuming normal cost of disposing of the
Properties.  The 10 yearly cash flows were then discounted to present worth
using discount rates of between 12.75% and 13.25% based upon local market and
property conditions.  The indicated value for the 33 Properties based upon the
discounted cash flow analysis is $92,620,000.

     In applying the sales comparison approach to the Properties, Wilson relied
upon an analysis of 64 sales of mini-warehouses between October 1997 and
September 1998.  Using a regression analysis, a statistically significant
correlation was derived between  the comparable property's net income and its
sales price per square foot.

                                       28
<PAGE>
 
     The indicated value for the 33 Properties based upon the sales comparison
approach ranged between $76,940,000 and $102,590,000.

     In addition, Wilson reviewed capitalization rates and purchase prices paid
in recent and pending transactions of properties similar to the Properties
involving Public Storage and others and has concluded that the Properties are
reasonably and appropriately valued relative to these other portfolio
transactions.

     Conclusions as to Value.  Wilson reconciled the values indicated from the
direct sales comparison and income approaches to arrive at a final valuation
conclusion.  Wilson gave primary emphasis to the income approach, an emphasis
deemed appropriate based on acquisition criteria currently employed in the mini-
warehouse market.

     Based on the valuation methodology described above, Wilson assigned a
market value to the Properties as of November 30, 1998 of $94,000,000.  The
resulting effective implied capitalization rate for the Properties based on
reported property operations (before non-recurring expenses and after certain
property tax adjustments) during the 12 months ended September 30, 1998 averaged
9.36%.

     Wilson's conclusion as to value relates to 100% of the Properties, which
includes the joint venture interests of both the Partnership and Public Storage.
Wilson did not separately value the interest of the Partnership in the
Properties.

     Assumptions, Limitations and Qualifications of the Appraisal.  The
appraisal reflects Wilson's valuation of the Properties as of November 30, 1998
in the context of the information available on such date.  Events occurring
after November 30, 1998 and before the closing of the merger could affect the
properties or assumptions used in preparing the appraisal.  Wilson has no
obligation to update the appraisal on the basis of subsequent events; however,
Wilson has informed the Partnership that, as of the date of this statement,
Wilson is not aware of any event or change in conditions since November 30, 1998
that may have caused a material change in the value of the Properties since that
date.

     The appraisal is subject to certain general and specific assumptions and
limiting conditions and is in conformity with the Departure Provision of Uniform
Standards of Professional Appraisal Practice.  Among other limitations, the
appraisal (i) did not consider the effect of easements, restrictions and other
similar items on the value of the Properties, (ii) assumed that the properties
comply with local building codes and zoning ordinances, (iii) assumed that there
are no new or planned facilities except as noted in the appraisal and (iv) did
not involve the physical inspections of competing properties.  See Appendix B
for a discussion of the specific assumptions, limitations and qualifications of
the appraisal.

     Compensation and Material Relationships.  Wilson is being paid an aggregate
fee of $82,500 for preparation of the appraisal, which fee includes
reimbursement for all of Wilson's related out-of-pocket expenses.  Wilson is
also entitled to indemnification against certain liabilities.  The fee was
negotiated with Wilson and payment is not dependent upon completion of the
merger.  As a leading appraiser of mini-warehouses since 1976, Wilson has
prepared appraisals for Public Storage and its affiliates, including appraisals
of the properties of other entities in connection with their mergers with Public
Storage, and Wilson is expected to continue to prepare appraisals for Public
Storage.  During the past three years (1995 to the present), Wilson has received
compensation aggregating approximately $903,000 for these services (exclusive of
amounts received in connection with the merger).

Fairness Opinion from Stanger

     Stanger was engaged by the Partnership to deliver a written opinion of its
determination as to the fairness of the consideration to be received in the
merger, from a financial point of view, to the public limited partners.  The
full text of the opinion, which contains a description of the assumptions and
qualifications made, matters considered and limitations on the review and
opinion, is set forth in Appendix C to this statement and should be read in its
entirety.  Certain of the material assumptions, qualifications and limitations
to the fairness opinion are set forth below.  The summary set forth below does
not purport to be a complete description of the analyses used by Stanger in
rendering the fairness opinion.  Arriving at a fairness opinion is a complex
analytical process not necessarily susceptible to partial analysis or amenable
to summary description.

                                       29
<PAGE>
 
     Except for certain assumptions, described more fully below, which the
Partnership advised Stanger that it would be reasonable to make, the Partnership
imposed no conditions or limitations on the scope of Stanger's investigation or
with respect to the methods and procedures to be followed in rendering the
fairness opinion.  The Partnership has agreed to indemnify Stanger against
certain liabilities arising out of its engagement to prepare and deliver the
fairness opinion.

     Experience of Stanger.  Stanger, founded in 1978, has provided information,
research, investment banking and consulting services to clients throughout the
United States, including major NYSE firms and insurance companies and over 70
companies engaged in the management and operation of partnerships and REITs.
The investment banking activities of Stanger include financial advisory
services, asset and securities valuations, industry and company research and
analysis, litigation support and expert witness services, and due diligence
investigations in connection with both publicly registered and privately placed
securities transactions.

     Stanger, as part of its investment banking business, is regularly engaged
in the valuation of businesses and their securities in connection with mergers,
acquisitions, reorganizations and for estate, tax, corporate and other purposes.
In particular, Stanger's valuation practice principally involves partnerships,
partnership securities and the assets typically owned through partnerships
including, but not limited to, oil and gas reserves, real estate, cable
television systems and equipment leasing assets.

     Summary of Materials Considered.  In the course of Stanger's analysis to
render its opinion regarding the merger, Stanger:  (i) reviewed this statement;
(ii) reviewed the annual reports on Form 10-K of Public Storage and the
Partnership for the three fiscal years ending December 31, 1995, 1996 and 1997
and the quarterly reports on Form 10-Q of Public Storage and the Partnership for
the quarters ended March 31, 1998, June 30, 1998 and September 30, 1998; (iii)
reviewed the appraisal prepared by Wilson and discussed with the general
partners and Wilson the methodologies and procedures employed in preparing the
appraisal; (iv) reviewed information regarding purchases and sales of self-
storage properties by Public Storage or any affiliated entities over the past
thirty months, and other information available relating to acquisition criteria
for self-storage properties; (v) reviewed estimates prepared by the Partnership,
and based in part on the appraisal, of the current net liquidation value per
Partnership unit of the Partnership's assets and projections of cash flow from
operations, cash distributions and going-concern values for the Partnership, and
the calculation of the allocation of such values between the joint venture
partners and between the limited and general partners; (vi) discussed with
certain members of management of Public Storage and the Partnership conditions
in self-storage property markets, conditions in the market for
sales/acquisitions of properties similar to those owned by the Partnership,
current and expected operations and performance, and the financial condition and
future prospects of Public Storage and the Partnership; (vii) reviewed
historical market prices, trading volume and dividends for Public Storage common
stock and historical secondary market transactions for Partnership units; and
(viii) conducted other studies, analyses, inquiries and investigations as
Stanger deemed appropriate.

     Summary of Analysis.  The following is a summary of certain financial and
comparative analyses reviewed by Stanger in connection with and in support of
its fairness opinion.  The summary of the opinion and analysis of Stanger set
forth in this statement is qualified in its entirety by reference to the full
text of such opinion.

     Review of Appraisal.  In preparing its opinion, Stanger relied upon the
appraisal of the Properties which was prepared as of November 30, 1998 by
Wilson, an independent appraiser.  Stanger reviewed the appraisal rendered by
Wilson, reviewed a sample of supporting documentation for the appraisal and
discussed with Wilson its experience and qualifications and the appraisal
methodologies utilized.

     Stanger observed that the appraisal was certified by a Member of the
Appraisal Institute and was conducted utilizing the income approach to
valuation, applying the discounted cash flow method to establish a value for
each individual property, and the sales comparison approach.

     Stanger observed that the effective capitalization rate utilized in the
appraisal was approximately 9.36%, based on net operating income (before non-
recurring expenses and after certain property tax adjustments) generated for the
12 months ended September 30, 1998. Lower capitalization rates generally reflect
higher sales prices for income-producing properties.

                                       30

     Review of Liquidation Analysis.  Stanger reviewed an analysis prepared by
the Partnership of the estimated value of the Partnership based upon liquidation
of its portfolio on a property-by-property basis utilizing estimates prepared by
the Partnership and information provided by Wilson.

     The liquidation analysis assumed each property could be sold within an
estimated marketing period of six months at the appraised value as reported in
the appraisal, to an independent third-party buyer.  Costs of such property
sales by the Partnership to independent third-parties were estimated by the
Partnership to total approximately $4,716,000 and were comprised of estimates of
$915,000 in state and local transfer taxes, $2,861,000 in commissions and
$940,000 in legal and other closing costs.  Such amounts were based on
prevailing transfer tax rates in the locale of each property and on estimates of
the Partnership based on knowledge of real estate transactions.  Stanger
observed that the estimated net proceeds from such liquidation, the sale of the
Partnership's interest in PSBP and the associated dissolution of the Partnership
and distribution of all remaining assets was $674 per Partnership unit, versus
the consideration offered in the merger of $697 cash per unit, or the equivalent
of $697 of Public Storage common stock per unit, based on the average closing
price of Public Storage common stock on the NYSE during the 20 consecutive
trading days ending on the fifth trading day prior to the Effective Date.

     Stanger also reviewed information on recent multi-property purchases and
sales of self-storage properties transacted by Public Storage, PSMI or
affiliates during the 30 months ending September 1998.  Stanger observed that
Public Storage, PSMI or affiliated entities have completed 11 bulk purchases of
property portfolios during the period reviewed, excluding the properties
associated with the mergers of 18 affiliated REITs with Public Storage.  These
transactions involved affiliated and unaffiliated entities with an interest in
73 properties with an aggregate acquisition cost of approximately $209 million.
Capitalization rates ranged from 9.1% to 11.6%, averaging 9.6%, for bulk
transactions during the period reviewed.

     Stanger also reviewed information regarding the merger between Public
Storage and Storage Trust Realty ("Storage Trust") which was closed in March
1999.  Stanger noted that in the merger Public Storage acquired a portfolio of
215 self-storage properties and certain other assets for aggregate consideration
of approximately $600 million, based on the price of Public Storage common stock
as of November 6, 1998.  Stanger also noted that in the context of rendering a
fairness opinion, the financial advisor to Storage Trust performed a net asset
valuation of Storage Trust based on a real estate valuation utilizing property
specific financial projections for 1999 and a direct capitalization method.  The
capitalization rates utilized in this analysis ranged from 9.5% to 10.5%.

     Based on the total transaction value of the Storage Trust merger and other
information cited in the proxy statement relating to the merger, the implied
trailing and forward capitalization rates of the Storage Trust portfolio in the
merger were estimated by Stanger to be approximately 8.7% and 9.3%,
respectively.  This capitalization rate does not reflect certain options and
benefits to be received by Public Storage as a result of the merger, including a
reduction in consolidated general and administrative expenses from the
elimination of certain duplicative administrative costs following the merger,
estimated at over $2 million on a pro forma basis for the nine months ending
September 30, 1998.

     Review of Going-Concern Analysis.  Stanger reviewed financial analyses and
projections prepared by the Partnership concerning estimated cash flows and
distributions from the Partnership's continued operation as an independent
stand-alone entity and estimated sales proceeds from the liquidation of the
Properties.  The analyses incorporated estimates of revenues and operating
expenses for the Properties, capital expenditures, entity-level general and
administrative costs, and cash flow distributions and proceeds from sale of the
Properties during a projection period of five years.  The analyses and
projections assumed, among other things, that (i) net operating income for the
Partnership would grow at a compound annual rate of approximately 3.7% over the
five-year projection period; (ii) general and administrative expenses would
increase at an average rate of 3.0% per annum over the projection period; and
(iii) the sale of the Properties would occur at the terminal value projected by
capitalizing the net operating income in year six at a capitalization rate of
9.8%, which was equal to the midpoint of (a) the effective implied
capitalization rate (at appraised values) for the Properties based upon reported
property operations (before non-recurring expenses and after certain property
tax adjustments) during the 12 months ended September 30, 1998 and (b) the
capitalization rate utilized in the residual value component of the discounted
cash flow analysis.  Real estate selling costs were assumed to be incurred at
the same percentage of sale proceeds (4.3%) as incurred in the 

                                       31
<PAGE>
 
liquidation alternative, and costs of liquidation of the PSBP units were assumed
at $0.06 per unit, consistent with the liquidation alternative.

     The Partnership evaluated its going-concern value by analyzing projected
cash flow and distributions assuming that the Partnership was operated as an
independent stand-alone entity and its assets sold in a liquidation of the
Partnership after a five-year holding period.  The projections also assume that
the Partnership's interest in PSBP is sold at an FFO multiple of 11.1 (reduced
by a commission of $0.06 per unit).  Distributions and sale proceeds per
Partnership unit were discounted in the projections at rates ranging from 12% to
13% (11.5% to 12.5% with respect to the interest in PSBP).

     Stanger observed that the estimated values per Partnership unit on a going-
concern basis resulting from the above analysis were $625 and $650, compared
with the consideration in the merger of $697 per Partnership unit.

     The estimated values assigned to the alternative forms of consideration are
based on a variety of assumptions that have been made by the Partnership.  While
the Partnership has advised Stanger that it believes that it has a reasonable
basis for these assumptions, these assumptions may not necessarily reflect the
Partnership's actual or future experience and such differences could be
material.  See "- Comparison of Consideration to be Received in the Merger to
Other Alternatives."

     Review of Tender Offer and Secondary Market Prices.  Stanger observed that
Partnership units have been purchased in recent months on the informal secondary
market for partnership securities and in 1994 and 1996 through tender offers by
Public Storage.

     Stanger observed that, based on prices reported to Stanger by various firms
active in the informal secondary market for partnership interests, the highest
selling prices reported for Partnership units in the informal secondary market
between January 1, 1997 and September 30, 1998 were $530 per unit compared with
the consideration in the merger of $697 per unit.

     Stanger also observed that the Partnership units had been the subject of
tender offers by Public Storage in 1994 and 1996 and the tender offer prices
ranged from $350 to $520 per unit.

     Distribution/FFO Analysis.  Stanger reviewed distributions per Partnership
unit and FFO per Partnership unit on an equivalent per unit basis.  Stanger
noted that based on a closing price of $27.75 for Public Storage common stock
and the resulting exchange ratio of Partnership units for Public Storage common
stock and based on operating results for Public Storage, regular quarterly
distributions per share would decrease by approximately $2.83 (33.9%) for
limited partners receiving Public Storage common stock.

     Stanger observed that, at the closing price of $27.75 for Public Storage
common stock and based on operating results for Public Storage, FFO for the nine
months ended September 30, 1998 per Partnership unit on a fully-diluted basis on
an equivalent per share basis earned by limited partners would decrease by $3.44
(7.7%).

     Conclusions.  Based on the foregoing, Stanger concluded that, based upon
its analysis and the limitations and qualifications contained in its opinion,
and as of the date of the fairness opinion, the consideration to be received in
the merger is fair to the public limited partners, from a financial point of
view.

     Assumptions.  In evaluating the merger, Stanger relied upon and assumed,
without independent verification, the accuracy and completeness of all financial
and other information contained in this statement or that was furnished or
otherwise communicated to Stanger.  Stanger did not perform an independent
appraisal of the assets and liabilities of Public Storage and the Partnership
and relied upon and assumed the accuracy of the appraisal.  Stanger also relied
on the assurances of Public Storage and the Partnership that any projections,
budgets, or value estimates contained in this statement or otherwise provided to
Stanger, were reasonably prepared on bases consistent with actual historical
experience and reflect the best currently available estimates and good faith
judgments; that the property values and the Partnership's net asset value have
been allocated between the joint venture partners and between the limited and
general partners in the same manner they would be allocated upon the
Partnership's liquidation; that no material changes have occurred in the
appraised value of the Properties or the information reviewed between the date
of the 

                                       32
<PAGE>
 
appraisal or the date of the other information provided and the date of the
opinion; and that Public Storage and the Partnership are not aware of any
information or facts that would cause the information supplied to Stanger to be
incomplete or misleading in any material respect.

     In connection with preparing the fairness opinion, Stanger was not engaged
to, and consequently did not, prepare any written report or compendium of its
analysis for internal or external use beyond the analysis set forth in Appendix
C.  Stanger does not intend to deliver any additional written summary of the
analysis.

     Compensation and Material Relationships.  For preparing the fairness
opinion and related services in connection with the merger, Stanger is being
paid a fee of $60,000.  In addition, Stanger will be reimbursed for certain out-
of-pocket expenses, including legal fees, up to a maximum of $9,000 and will be
indemnified against certain liabilities, including certain liabilities under the
federal securities laws.  The fee was negotiated with Stanger.  Payment of the
fee to Stanger is not dependent upon completion of the merger.  Stanger has
rendered consulting and related services and provided products to Public Storage
and to PSMI and its affiliates, including fairness opinion to the public
shareholders of 18 REITs in connection with their mergers with Public Storage,
and may be engaged in the future.  During the past four years (1995 to the
present), Stanger has received compensation aggregating approximately $1,070,000
for these services and products (exclusive of amounts received in connection
with the merger).

     Limitations and Qualifications.  Stanger was not requested to, and
therefore did not:  (i) select the method of determining the consideration being
paid in the merger; (ii) make any recommendation to the public limited partners
with respect to whether to approve or reject the merger or whether to select the
cash or Public Storage common stock option in the merger; or (iii) express any
opinion as to the business decision to effect the merger, alternatives to the
merger or tax factors resulting from the merger, or relating to Public Storage's
continued qualification as a REIT.  Stanger's opinion is based on business,
economic, real estate and securities markets, and other conditions as of the
date of its analysis.  Events occurring after that date may materially affect
the assumptions used in preparing the opinion.

     Among the factors considered in the selection of Stanger were Stanger's
experience in connection with the mergers of 18 affiliated REITs with Public
Storage and in connection with the merger of two similar partnerships with
Public Storage, its expertise in real estate transactions and the fee quoted by
Stanger.  No party other than Stanger was contacted to render an opinion as to
the fairness of the merger to public limited partners, and the Partnership has
neither requested nor received any views, preliminary or otherwise, from any
party other than Stanger regarding the fairness of the merger to the public
limited partners.

The Merger Agreement

     If the conditions to the merger are satisfied or waived, the merger will be
consummated pursuant to the merger agreement which is set forth in Appendix A
to, and is incorporated by reference into, this statement.  As a result of the
merger, all of the Partnership units will be held by a subsidiary of Public
Storage.  The merger agreement contains representations and warranties of Public
Storage and the Partnership and certain other provisions relating to the merger.
The representations and warranties are extinguished by, and do not survive, the
merger.

     Conditions to Consummation of the Merger.  Consummation of the merger is
contingent upon standard conditions, including the following:  (i) the
Registration Statement shall have been declared effective by the Commission and
Public Storage shall have received all other authorizations necessary to issue
Public Storage common stock in exchange for Partnership units and to consummate
the merger; (ii) the merger agreement and the merger shall have been approved
and adopted by the requisite vote of the limited partners (which condition has
been satisfied by Public Storage's vote of its Partnership units in favor of the
merger); (iii) the shares of Public Storage common stock issued to limited
partners shall be listed on the NYSE; (iv) the Partnership shall have received a
fairness opinion from Stanger (which opinion has been received); (v) no legal
action challenging the merger shall be pending; and (vi) in the case of Public
Storage, the average of the per share closing prices on the NYSE of the Public
Storage common stock during the 20 consecutive trading days ending on the fifth
trading day prior to the Effective Date is not less than $25.  The obligation of
Public Storage to effect the merger is also subject to Public Storage, in its

                                       33
<PAGE>
 
sole discretion, being satisfied as to title to, and the results of an
environmental audit of, the Properties.  Any of these conditions may be waived
by the board of directors of Public Storage.

     Amendment or Termination.  The merger agreement provides for amendment or
modification thereof with respect to the merger by written agreement authorized
by the board of directors of Public Storage and the general partners.  The
merger may be abandoned at any time before or after shareholder approval by
mutual written consent and may be abandoned by either party if, among other
things, the closing of the merger has not occurred on or before June 30, 1999.

     Consummation.  It is contemplated that the merger will be consummated by
filing a certificate of merger with the California Secretary of State.

     Certificates for Public Storage Common Stock.  After the merger, holders of
Partnership units that were converted into shares of Public Storage common
stock, without any further action, will be entitled to receive certificates
representing the number of whole shares of Public Storage common stock into
which Partnership units will have been converted and cash payment in lieu of
fractional share interests, if applicable.  As soon as practicable after the
merger, the exchange agent, BankBoston, N.A., will send the certificates for the
Public Storage common stock to each holder of Partnership units whose
Partnership units have been converted into shares of Public Storage common
stock.  HOLDERS OF PARTNERSHIP UNITS WHO INTEND TO RECEIVE PUBLIC STORAGE COMMON
STOCK IN THE MERGER DO NOT NEED TO TAKE ANY ACTION TO RECEIVE THEIR RESPECTIVE
CERTIFICATES REPRESENTING THE PUBLIC STORAGE COMMON STOCK.  IT IS IMPORTANT THAT
YOU MAKE SURE YOU RECEIVE YOUR CERTIFICATE FOR THE PUBLIC STORAGE COMMON STOCK
MAILED TO YOU BY BANKBOSTON, N.A.  IF YOU DO NOT RECEIVE YOUR PUBLIC STORAGE
COMMON STOCK CERTIFICATE BY MAY 31, 1999, CALL BANKBOSTON, N.A. AT (781) 575-
3120 SO THAT AN AFFIDAVIT OF NON-RECEIPT CAN BE SENT TO YOU AND A CERTIFICATE
REISSUED AT NO COST TO YOU.  ANY SHAREHOLDER WHO CONTACTS BANKBOSTON, N.A. AFTER
OCTOBER 31, 1999 REQUESTING THAT A CERTIFICATE BE REISSUED MAY NEED TO EXECUTE
AN AFFIDAVIT OF LOSS AND PAY THE COST OF A BOND OF INDEMNITY BEFORE A
CERTIFICATE CAN BE REPLACED.

     After the merger, there will be no further registration of transfers of
Partnership units on the Partnership's records.

     Fractional Shares.  No fractional shares of Public Storage common stock
will be issued in the merger.  In lieu of any fractional share interests, each
holder of Partnership units who would otherwise be entitled to a fractional
share of Public Storage common stock will receive a whole share of Public
Storage common stock if such fractional share to which such holder would
otherwise have been entitled is .5 of a share or more, and such fractional share
shall be disregarded if it represents less than .5 of a share; provided that
such fractional share shall not be disregarded if it represents .5 of 1% or more
of the total number of shares of Public Storage common stock such holder is
entitled to receive in the merger.  In such event, the holder will 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 Public Storage
common stock at the time of effectiveness of the merger by (ii) the fractional
interest.

     Restrictions on Other Acquisitions.  The Partnership has agreed not to
initiate, solicit or encourage, directly or indirectly, any inquiries or the
making of any proposal with respect to a merger, consolidation, securities
exchange or similar transaction involving it, or any purchase of all or any
significant portion of its assets, or any equity interest in it, other than the
transactions contemplated by the merger agreement, or engage in any negotiations
concerning, or provide any confidential information or data to, or have
discussions with, any person relating to such a proposal, provided that the
general partners 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 participation in the negotiations and discussions might cause the Partnership
to breach their fiduciary duty to limited partners under applicable law as
advised by counsel.  The Partnership has agreed to notify Public Storage
immediately if inquiries or proposals are received by, any such information is
requested from, or negotiations or discussions are sought to be initiated or
continued with it, and to keep Public Storage informed of the status and terms
of any such proposals and any such negotiations or discussions.

                                       34
<PAGE>
 
     Distributions.  Pending the merger, the Partnership is precluded from
declaring or paying any distributions to the limited partners other than (i)
regular distributions at a quarterly rate not in excess of $8.36 per Partnership
unit and (ii) distributions to the limited partners immediately prior to the
effectiveness of the merger equal to the amount by which the Partnership's
estimated net asset value allocable to limited partners as of the date of the
merger exceeds $697 per Partnership unit.  See "- Determination of Payments to
be Received by Limited Partners in the Merger."

Cash Election Procedure

     Each holder of record of Partnership units may make a cash election to have
his or her Partnership units converted into the right to receive cash in the
merger.  All cash elections are to be made on a cash election form.  A cash
election form is being sent to all holders of record of Partnership units on the
date of this statement.  To be effective, a cash election form must be properly
completed and signed and must be received by the exchange agent, BankBoston,
N.A., no later than 5:00 p.m. New York City time on April 29, 1999.  Holders of
record of units who hold units as nominees, trustees or in other representative
capacities may submit multiple cash election forms, provided that such
representative certifies that each such cash election form covers all the units
held by such representative for a particular beneficial owner.  Any cash
election form may be revoked by written notice received by the exchange agent
prior to 5:00 p.m., New York City time, on April 29, 1999.  In addition, all
cash election forms will automatically be revoked if the exchange agent is
notified in writing that the merger has been abandoned.  The exchange agent may
determine whether or not elections to receive cash have been properly made or
revoked, and any such determination shall be conclusive and binding.

     A holder of Partnership units may not make a cash election as to less than
all of the units owned by such holder.  Any holder of units who does not submit
a properly completed and signed cash election form which is received by the
exchange agent prior to 5:00 p.m., New York City time, on April 29, 1999 will
receive Public Storage common stock in the merger.  If Public Storage or the
exchange agent determines that any purported cash election was not properly
made, such purported cash election will be deemed to be of no force and effect
and the holder of units making such purported cash election will, for purposes
hereof, receive Public Storage common stock in the merger.  None of Public
Storage, the Partnership or the exchange agent will be under any obligation to
notify any person of any defect in a cash election form.

     The tax consequences of receiving cash or Public Storage common stock are
described under "Federal Income Tax Considerations - The Merger."

Consequences to the Partnership if the Merger is Not Completed

     If the merger is not completed, the Partnership will continue as a publicly
owned entity.

Costs of the Merger

     It is estimated that the total consideration (cash and Public Storage
common stock) to be paid by Public Storage to acquire all of Partnership units
owned by the public limited partners in the merger and to pay related costs and
expenses would be approximately $23,285,000.  These amounts will be paid from
Public Storage's working capital or with funds borrowed under credit facilities
with a group of banks for which Wells Fargo Bank, National Association acts as
agent.  These credit facilities aggregate $150,000,000 and bear interest at
LIBOR plus .40% to 1.10%.  Public Storage intends to repay amounts borrowed
under these facilities from the public or private placement of securities or
from Public Storage's undistributed cash flow.

     If the merger is completed, all costs incurred by Public Storage and the
Partnership in connection with the merger will be paid by Public Storage.  If
the merger is not completed, all costs incurred in connection with the merger
will be paid by the party incurring such costs, except that Public Storage will
pay one-half of the cost of any expenses incurred in connection with the
printing of this statement and related registration statement, the appraisal,
environmental and structural audits and filing fees and the Partnership will pay
the other one-half of such costs.  The Partnership's share of such costs would
be paid from its working capital.

     Limited partners who receive Public Storage common stock in the merger will
 be changing their investment from "finite-life" to "infinite-life"; they will
 be able to realize the value of their investment only by selling the Public
 Storage common stock.  The interest of Public Storage shareholders can be
 diluted through the issuance of additional securities, including securities
 that would have priority over Public Storage common stock as to cash flow,
 distributions and liquidation proceeds.  Public Storage has an effective
 registration statement for preferred stock, common stock, equity stock and
 warrants and intends to issue additional securities under this registration
 statement.  There is no assurance that any such securities will be issued.  See
 "Risk Factors - Uncertainty Regarding Market Price of Public Storage Common
 Stock" and "- Financing Risks - Dilution and Subordination."

     Public Storage has no plans with respect to a sale or financing of any of

     Given Public Storage's control of all voting decisions with respect to the
 Partnership, both Public Storage and the Partnership can enter into
 transactions with affiliates without the need for approval of the public
 shareholders and public limited partners, respectively.  In the case of Public
 Storage, however, these transactions require approval of Public Storage's
 independent directors.

     Because Public Storage owns substantially more property interests in more
 states than the Partnership, Public Storage's results of operations are less
 affected by the profitability or lack of profitability of a single property
 than are those of the Partnership and it would be more difficult to liquidate
 Public Storage than the Partnership within a reasonable period of time.

     Distributions are paid to limited partners from cash available for
 distribution.  Public Storage is required to distribute at least 95% of its
 ordinary REIT taxable income in order to maintain its qualification as a REIT.
 Public Storage distributes less than its cash available for distribution
 (recently distributing amounts approximately equal to its taxable income),
 permitting it to retain funds for additional investment and debt reduction.

     A limited partner who receives Public Storage common stock in the merger
 will have an investment for which the market is broader and more active than
 the market for Partnership units.  Distributions on Public Storage common stock
 are lower than the distributions on the Partnership units.  Distributions on
 Public Storage common stock also are subject to priority of preferred stock.

     The Partnership is a pass-through entity, whose income and loss is not
 taxed at the entity level but instead allocated directly to the limited and
 general partners.  Limited partners are taxed on income or loss allocated to
 them, whether or not cash distributions are made to them.  In contrast, Public
 Storage qualifies as a REIT, allowing it to deduct dividends paid to its
 shareholders.  To the extent Public Storage has net income (after taking into
 account the dividends paid deduction), such income will be taxed at the
 corporate level at the standard corporate tax rates.  Dividends paid to Public
 Storage shareholders will constitute portfolio income and not passive income.

     The general partners have, under most circumstances, no liability to the
 Partnership for acts or omissions it undertakes when performed in good faith,
 in a manner reasonably believed to be within the scope of their authority and
 in the best interests of the Partnership.  The general partners also have,
 under specified circumstances, a right to be reimbursed by the Partnership for
 liability, loss, damage, costs and expenses they incur by virtue of serving as
 general partners.  Although the standards are expressed somewhat differently,
 there are similar protections from liability available to directors and
 officers of Public Storage when acting on behalf of Public Storage and rights
 of directors and officers to seek indemnification from Public Storage.  Public
 Storage believes that the scope of the liability and indemnification provisions
 in Public Storage's governing documents provides protection against claims for
 personal liability against Public Storage's directors and officers which is
 comparable to, though not identical with, the protections afforded to the
 general partners under the partnership agreement.

General

     This statement is first being mailed on or about April 1, 1999 to limited
partners in connection with the merger and the amendment to the partnership
agreement.  The general partners are not soliciting proxies in connection with
these matters.

     Holders of record at the close of business on the date of this statement
will be entitled to receive notice of the merger and the amendment to the
partnership agreement.  On such date, there were outstanding 128,000 Partnership
units.  As of the record date, Public Storage beneficially owned 94,947 units
(approximately 74% of the units).

     The affirmative vote of a majority of the Partnership units is required to
approve the merger and the amendment.  As indicated above, the general partners
are not soliciting proxies from the limited partners in connection with these
matters.  Public Storage owns sufficient units to approve the merger and the
amendment without the vote of any other limited partner and has approved these
matters by written consent in accordance with California law and the partnership
agreement.  The merger and the amendment will become effective upon the signing
of the amendment and the filing of a certificate of merger with the California

                          CERTAIN RELATED TRANSACTIONS

     The following are the principal relationships between Public Storage and
the Partnership:

     Joint Venture Interests.  Public Storage owns a joint venture interest
(ranging from approximately 10% to 64%) in 27 of the Properties and a 0.7%
interest in PSBP.  Under the joint ventures, certain special allocation rules
apply and Public Storage has the right to compel the sale of the Properties.
See Note (1) to the Notes to Consolidated Financial Statements of the
Partnership.  (Appendix E).

     General Partners' Interest.  Public Storage and Hughes are general partners
of the Partnership. Public Storage receives incentive distributions equal to 10%
of the Partnership's cash flow and has a subordinated interest in proceeds from
sales or financings of the Properties (15% of such proceeds so long as limited
partners have received sale or financing distributions equal to their capital
contributions plus any deficiency in a simple 8% annual return).  In 1995, 1996
and 1997, the general partners received from the Partnership approximately
$890,000, $480,000 and $551,000, respectively, in respect of their incentive
distributions.  The general partners also have a 1% interest in the Partnership
in respect of their capital contributions and participate in Partnership
distributions in proportion to their interest in the Partnership.

     Property Management.  The Properties are managed by Public Storage and PSBP
pursuant to management agreements under which the property managers receive 6%
and 5% of gross revenues from operations of the mini-warehouse and commercial
space (prior to the contribution of these properties to PSBP), respectively.  In
1995, 1996 and 1997, the property managers received approximately $872,000,
$900,000 and $817,000, respectively, from the Partnership.

     Limited Partner Interests.  Of the 128,000 outstanding Partnership units,
94,947 units (approximately 74%) are beneficially owned by Public Storage.
Public Storage participates in Partnership distributions on the same terms as
other holders of units in respect of units owned by Public Storage.

     PSBP.  The Partnership owns a 1.9% interest in PSBP directly and a 0.7%
interest in PSBP jointly with Public Storage.  Public Storage has a significant
ownership interest in PSBP.

                    DESCRIPTION OF PARTNERSHIP'S PROPERTIES

     The Partnership is a California limited partnership organized in 1983,
which raised $64,000,000 from the sale of 128,000 units at $500 per unit in a
registered public offering of the units completed in June 1984.  All of the
Partnership's net proceeds of that offering were invested in mini-warehouses
and, to a lesser extent, business parks.  The Partnership transferred its
business parks to PSBP.

     The Partnership and Public Storage jointly own 27 of the 33 Properties and
the remaining six are owned by the Partnership alone.  All of the Properties are
mini-warehouses.  Mini-warehouses 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 which ranges generally from 25 to 400 square feet.

     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.

     The following table sets forth information as of September 30, 1998 about
the Properties.

(1)  Represents a leasehold interest.

     In November 1994, a regulatory agency condemned a property owned jointly by
Public Storage and the Partnership.  The Partnership received initial
condemnation proceeds of approximately $1.9 million.  The Partnership is
contesting this amount.  In November 1998, a jury awarded the Partnership an
additional approximately $1.6 million plus interest.  However, the regulatory
agency is seeking to have this award vacated.  The estimated value per
Partnership unit reflects the Partnership's share of the estimated proceeds from
the jury award.

     As of the date of this statement, each of the Properties is generating
sufficient revenues to cover its operating expenses.  None of the Properties is
subject to any material mortgage, lien, or any encumbrance other than liens for
taxes and assessments not yet due or payable, utility easements or other
immaterial liens or encumbrances.  Each of the Properties will continue to be
used for its current purpose.  At present, the Partnership has no plans for any
material renovation or improvement of its properties.  However, the Partnership
budgets for regular maintenance, repair and upgrade to its properties.  The
Partnership believes each of its properties is adequately covered by insurance.

     Competition exists in all of the market areas in which the Properties are
located, and the barriers to entry are relatively low for competitors with the
necessary capital.  However, the Partnership believes that the current overall
demand for mini-warehouse space is strong, and as reflected in the table below
the overall performance of the Properties has generally improved.  The
Properties are, and will continue after the merger to be, operated as part of
the "Public Storage" system by Public Storage, the largest operator of mini-
warehouses in the United States.

     Set forth below is a schedule showing the overall occupancy rate and
realized rent for the Properties for the periods indicated:

                   DESCRIPTION OF PUBLIC STORAGE'S PROPERTIES

     At September 30, 1998, Public Storage had equity interests (through direct
ownership, as well as general and limited partnership interests and stock
ownership interests) in 1,188 facilities (598 of which were wholly-owned)
located in 38 states.  These facilities consist of 1,089 mini-warehouses and 99
business parks.  None of Public Storage's current investments involves 10% or
more of Public Storage's total assets or gross revenues.

     For a general description of mini-warehouses, see "Description of
Partnership Properties."

     The following table reflects the geographic diversification of Public
Storage's mini-warehouses ("Mini") and business parks ("BP"):

     (1)  Includes properties that combine mini-warehouse and business park
space.


     As of the date of this statement, each of Public Storage's properties is
generating sufficient revenues to cover its operating expenses other than
properties in the initial lease-up stage.  Only 25 of Public Storage's
properties are subject to any material mortgage, lien, or any encumbrance other
than liens for taxes and assessments not yet due or payable, utility easements
or other immaterial liens or encumbrances.  As of September 30, 1998, these 25
properties are encumbered by mortgages in the aggregate amount of $35,992,000,
bearing interest at rates ranging from 7.13% to 11.0% per year and maturing
between May 1999 and September 2028.  Each of Public Storage's properties will
continue to be used for its current purpose.  At present, Public Storage has no
plans for any material renovation or improvement of its properties.  However,
Public Storage budgets for regular maintenance, repair and upgrade to its
properties.  Public Storage believes each of its properties is adequately
covered by insurance.

     Competition exists in substantially all of the market areas in which Public
Storage's mini-warehouses and commercial properties are located, and the
barriers to entry are relatively low for competitors with the necessary capital.
However, Public Storage believes that the current overall demand for mini-
warehouse and commercial space is strong, and as reflected in the table below
the overall performance of Public Storage's mini-warehouses and commercial
properties has generally improved.  More than 10% of Public Storage's net
rentable square feet of space are located in each of the Southern California,
Northern California and Texas market areas.  The economy of each of 

                                       53
<PAGE>
 
those markets has been strengthening. Public Storage's mini-warehouses are
operated as part of the "Public Storage" system. Public Storage is the largest
operator of mini-warehouses in the United States.

     Set forth below is a schedule showing the overall occupancy rate and
realized rent for the 985 mini-warehouses in which Public Storage had an
interest, direct or indirect, for the periods indicated.

     On March 12, 1999, Public Storage and Storage Trust Realty ("Storage
Trust"), a New York Stock Exchange listed REIT, completed a merger.  As a result
of the merger Public Storage acquired 215 self-storage facilities located in 16
states totaling approximately 12.0 million net rentable square feet and
approximately 104,000 units.  In the merger, each common share of beneficial
interest of Storage Trust was exchanged for 0.86 shares of Public Storage's
common stock (approximately 13.0 million shares of Public Storage's common stock
were issued in the merger with an additional approximately 1.0 million shares
reserved for issuance upon conversion of units in Storage Trust's operating
partnership).  In connection with the merger, Public Storage assumed
approximately $200 million of debt.  In connection with the merger, Public
Storage's board of directors was expanded by one seat and Daniel C. Staton,
previously Storage Trust's Chairman of the Board of Trustees, was elected as a
new member of Public Storage's board of directors.  The merger was structured as
a tax-free transaction.  For additional information on this merger, you should
read Public Storage's most recent reports filed with the Commission.

    record on March 15, 1999.

     As of December 31, 1998, there were approximately 23,356 record holders of
Public Storage common stock. On March __, 1999, the last full trading day prior
to the date of this statement, the closing price of the Public Storage common
stock was $_______.

     Holders of Public Storage common stock are entitled to receive
distributions when, as and if declared by the board of directors out of any
funds legally available for that purpose.  Public Storage, as a REIT, is
required to distribute annually at least 95% of its "REIT taxable income,"
which, as defined by the relevant tax statutes and regulations, is generally
equivalent to net taxable ordinary income.  Under certain circumstances, Public
Storage can rectify a failure to meet this distribution requirement by paying
dividends after the close of a particular taxable year.  See "Federal Income Tax
Considerations - General Tax Treatment of Public Storage."

     Public Storage's revolving credit facility with a commercial bank restricts
Public Storage's ability to pay distributions in excess of "Funds from
Operations" for the prior four fiscal quarters less scheduled principal payments
and less capital expenditures. Funds from Operations is defined in the loan
agreement generally as net income before gain on sale of real estate,
extraordinary loss on early retirement of debt and deductions for depreciation,
amortization and non-cash charges.  Also, unless full dividends on Public
Storage's preferred stock have been paid for all past dividend periods, no
dividends may be paid on Public Storage common stock, except in certain
instances.

         per unit.

     Holders of Partnership Units.  As of December 31, 1998, there were
approximately 1,632 record holders of Partnership units.

     Sales of Partnership Units.  The Partnership units are not listed on any
national securities exchange or quoted in the over the counter market, and there
is no established public trading market for the units.  Secondary sales activity
for the units has been limited and sporadic.  The general partners monitor
transfers of the units (i) because the admission of the transferee as a
substitute limited partner requires the consent of the general partners under
the partnership agreement, (ii) in order to track compliance with safe harbor
provisions to avoid treatment as a "publicly traded partnership" for tax
purposes and (iii) because Public Storage has purchased units.  However, the
general partners do not have information regarding the prices at which all
secondary sales transactions in the units have been effectuated.  Various
organizations offer to purchase and sell limited partnership interests (such as
the units) in secondary sales transactions.  Various publications such as The
Stanger Report summarize and report information (on a monthly, bimonthly or less
frequent basis) regarding secondary sales transactions in limited partnership
interests (including the units), including the prices at which such secondary
sales transactions are effectuated.

     The general partners estimate, based solely on the transfer records of the
Partnership and the Partnership's transfer agent, that the number of Partnership
units transferred in sales transactions (i.e., excluding transactions believed
to be between related parties, family members or the same beneficial owner) was
as follows:

and 225,000 shares of equity stock.

Common Stock

     The following description of Public Storage common stock sets forth certain
general terms and provisions of Public Storage common stock.  The statements
below describing Public Storage common stock are in all respects subject to and
qualified in their entirety by reference to the applicable provisions of the
Public Storage's articles of incorporation and bylaws.

     Public Storage shareholders will be entitled to receive dividends when, as
and if declared by Public Storage's Board of Directors, out of funds legally
available therefor.  Payment and declaration of dividends on Public Storage
common stock and purchases of shares thereof by Public Storage will be subject
to certain restrictions if Public Storage fails to pay dividends on outstanding
preferred stock.  See "- Preferred Stock."  Upon any liquidation, dissolution or
winding up of Public Storage, holders of Public Storage common stock will be
entitled to share equally and ratably in any assets available for distribution
to them, after payment or provision for payment of the debts and other
liabilities of Public Storage and the preferential amounts owing with respect to
any outstanding preferred stock.  Holders of Public Storage common stock have no
preemptive rights, which means they have no right to acquire any additional
shares of Public Storage common stock that may be issued by Public Storage at a
subsequent date.

     Each outstanding share of Public Storage common stock entitles the holder
to one vote on all matters presented to Public Storage shareholders for a vote,
with the exception that Public Storage shareholders have cumulative voting
rights with respect to the election of the Board of Directors, in accordance
with California law.  Cumulative voting entitles each Public Storage shareholder
to cast as many votes as there are directors to be elected multiplied by the
number of shares registered in his or her name.  A Public Storage shareholder
may cumulate the votes for directors by casting all of the votes for one
candidate or by distributing the votes among as many candidates as the Public
Storage shareholder chooses.  Public Storage shareholders have no preemptive or
other rights to subscribe for or purchase additional shares of Public Storage
common stock.  All outstanding shares of Public Storage common stock are fully
paid and nonassessable.

Ownership Limitations

     In a series of transactions among Public Storage Management, Inc. and its
affiliates (collectively, "PSMI"), culminating in the November 16, 1995 merger
of PSMI into Storage Equities, Inc. ("SEI") (the "PSMI Merger"), SEI became
self-administered and self-managed, acquired substantially all of PSMI's United
States real estate interests and was renamed "Public Storage, Inc."

     For Public Storage to qualify as a REIT under the Code, no more than 50% in
value of its outstanding shares of capital stock may be owned, directly or
constructively under the applicable attribution rules of the Code, by five or
fewer individuals (as defined in the Code to include certain entities) during
the last half of a taxable year.  In order to maintain its qualification as a
REIT, Public Storage's articles of incorporation and bylaws provide certain
restrictions on the shares of capital stock that any Public Storage shareholder
may own.

     Public Storage's articles of incorporation and bylaws provide that, subject
to certain exceptions, no holder may own, or be deemed to own by virtue of the
attribution provisions of the Code, more than (A) 2.0% of the outstanding shares
of all common stock of Public Storage, or (B) 9.9% of the outstanding shares of
each class or series of shares of preferred stock or equity stock of Public
Storage.  The articles of incorporation and bylaws provide, however, that no
person shall be deemed to exceed the ownership limit solely by reason of the
beneficial ownership of shares of any class of stock to the extent that such
shares of stock were beneficially owned by such person (including 

                                       59
<PAGE>
 
the Hughes family) at the time of the PSMI Merger. This ownership limitation was
established in order to assist in preserving Public Storage's REIT status in
view of the Hughes family's substantial ownership interest in Public Storage.
See "Federal Income Tax Considerations - General Tax Treatment of Public
Storage."

     Public Storage's Board of Directors, in its sole and absolute discretion,
may grant an exception to the ownership limits to any person so requesting, so
long as (A) the Board of Directors has determined that, after giving effect to
(x) an acquisition by such person of beneficial ownership (within the meaning of
the Code) of the maximum amount of capital stock of Public Storage permitted as
a result of the exception to be granted and (y) assuming that the four other
persons who would be treated as "individuals" for the purposes of Section
542(a)(2) of the Code and who would beneficially own the largest amounts of
stock of Public Storage (determined by value) beneficially own the maximum
amount of capital stock of Public Storage permitted under the ownership limits
(or any waivers of the ownership limits granted with respect to such persons),
Public Storage would not be "closely held" within the meaning of Section 856(h)
of the Code and would not otherwise fail to qualify as a REIT, and (B) such
person provides to Public Storage's Board of Directors such representations and
undertakings as the Board of Directors may require.  Notwithstanding any of the
foregoing ownership limits, no holder may own or acquire, either directly,
indirectly or constructively under the applicable attribution rules of the Code,
any shares of any class of Public Storage's capital stock if such ownership or
acquisition (i) would cause more than 50% in value of Public Storage's
outstanding capital stock to be owned, either directly or constructively, under
the applicable attribution rules of the Code, by five or fewer individuals (as
defined in the Code to include certain tax-exempt entities, other than, in
general, qualified domestic pension funds), (ii) would result in Public
Storage's stock being beneficially owned by less than 100 persons (determined
without reference to any rules of attribution), or (iii) would otherwise result
in Public Storage's failing to qualify as a REIT.

     Public Storage's articles of incorporation and bylaws provide that, if any
holder of Public Storage's capital stock purports to transfer shares to a person
or there is a change in the capital structure of Public Storage and either the
transfer or the change in capital structure would result in Public Storage
failing to qualify as a REIT, or such transfer or the change in capital
structure would cause the transferee to hold shares in excess of the applicable
ownership limit, then the stock being transferred (or in the case of an event
other than a transfer, the stock beneficially owned) which would cause one or
more of the restrictions on ownership or transfer to be violated shall be
automatically transferred to a trust for the benefit of a designated charitable
beneficiary.  The purported transferee of such shares shall have no right to
receive dividends or other distributions with respect to such shares and shall
have no right to vote such shares.  Any dividends or other distributions paid to
such purported transferee prior to the discovery by Public Storage that the
shares have been transferred to a trust shall be paid to the trustee of the
trust for the benefit of the charitable beneficiary upon demand.  The trustee of
the trust will have all rights to dividends with respect to shares of stock held
in trust, which rights will be exercised for the exclusive benefit of the
charitable beneficiary.  Any dividends or distributions paid over to the trustee
will be held in trust for the charitable beneficiary.  The trustee shall
designate a transferee of such stock so long as such shares of stock would not
violate the restrictions on ownership or transfer in the Public Storage articles
of incorporation or bylaws in the hands of such designated transferee.  Upon the
sale of such shares, the purported transferee shall receive the lesser of (A)(i)
the price per share such purported transferee paid for the stock in the
purported transfer that resulted in the transfer of the shares to the trust, or
(ii) if the transfer or other event that resulted in the transfer of the shares
of the trust was not a transaction in which the purported transferee gave full
value for such shares, a price per share equal to the market price on the date
of the purported transfer or other event that resulted in the transfer of the
shares to the trust and (B) the price per share received by the trustee from the
sale or other disposition of the shares held in the trust.

Class B Common Stock

     The Public Storage class B common stock (i) does not participate in
distributions until the later to occur of Funds from Operations ("FFO") per
Common Share (as defined below by Public Storage) aggregating $1.80 during any
period of four consecutive calendar quarters, or January 1, 2000; thereafter,
the Public Storage class B common stock will participate in distributions (other
than liquidating distributions), at the rate of 97% of the per share
distributions on the Public Storage common stock, provided that cumulative
distributions of at least $.22 per quarter per share have been paid on the
Public Storage common stock, (ii) does not participate in liquidating
distributions, (iii) is not entitled to vote (except as expressly required by
California law) and (iv) will automatically convert into Public Storage common
stock, on a share for share basis, upon the later to occur of FFO per Common
Share aggregating $3.00 during any period of four consecutive calendar quarters
or January 1, 2003.

                                       60
<PAGE>
 
     For these purposes:

     (1) FFO means net income (loss) (computed in accordance with GAAP) before
(i) gain (loss) on early extinguishment of debt, (ii) minority interest in
income and (iii) gain (loss) on disposition of real estate, adjusted as follows:
(i) plus depreciation and amortization (including Public Storage's pro-rata
share of depreciation and amortization of unconsolidated equity interests and
amortization of assets acquired in the PSMI Merger, including property
management agreements and goodwill), and (ii) less FFO attributable to minority
interest.  FFO is a supplemental performance measure for equity REITs as defined
by the National Association of Real Estate Investment Trusts, Inc. ("NAREIT").
The NAREIT definition does not specifically address the treatment of minority
interest in the determination of FFO or the treatment of the amortization of
property management agreements and goodwill.  In the case of Public Storage, FFO
represents amounts attributable to its shareholders after deducting amounts
attributable to the minority interests and before deductions for the
amortization of property management agreements and goodwill.  FFO does not take
into consideration scheduled principal payments on debt, capital improvements,
distributions and other obligations of Public Storage.  Accordingly, FFO is not
a substitute for Public Storage's cash flow or net income as a measure of its
liquidity or operating performance or ability to pay distributions.

     (2) FFO per Common Share means FFO less preferred stock dividends (other
than dividends on convertible preferred stock) divided by the outstanding
weighted average shares of Public Storage common stock assuming conversion of
all outstanding convertible securities and the Public Storage class B common
stock.

Preferred Stock

     Public Storage is authorized to issue 50,000,000 shares of preferred stock,
$.01 par value per share.  Public Storage's articles of incorporation provide
that the preferred stock may be issued from time to time in one or more series
and give the Board of Directors broad authority to fix the dividend and
distribution rights, conversion and voting rights, if any, redemption provisions
and liquidation preferences of each series of preferred stock.

     At March 15, 1999, Public Storage had 12 series of senior preferred stock
outstanding.  In all respects, each of the series of senior preferred stock
ranks on a parity with each other.  Each of the series of senior preferred stock
(i) has a stated value of $25.00 per share, (ii) in preference to the holders of
shares of the common stock and any other capital stock ranking junior to the
senior preferred stock as to payment of dividends, provides for cumulative
quarterly dividends calculated as a percentage of the stated value (ranging from
8% to 10% per year in the case of the 11 series of fixed rate senior preferred
stock and a rate adjustable quarterly ranging from 6.75% to 10.75% per year in
the case of a series of adjustable rate senior preferred stock) and (iii) is
subject to redemption, in whole or in part, at the option of Public Storage at a
cash redemption price of $25.00 per share, plus accrued and unpaid dividends (on
and after June 30, 1999 in the case of the adjustable rate senior preferred
stock and on or after various dates between December 31, 2000 and April 30, 2005
in the case of the series of fixed rate senior preferred stock).

     In the event of any voluntary or involuntary liquidation, dissolution or
winding up of Public Storage, the holders of each of the series of senior
preferred stock will be entitled to receive out of Public Storage's assets
available for distribution to stockholders, before any distribution of assets is
made to holders of Public Storage common stock or any other shares of capital
stock ranking as to such distributions junior to the senior preferred stock,
liquidating distributions in the amount or equivalent amount of $25.00 per
share, plus all accrued and unpaid dividends.

     Except as expressly required by law and in certain other limited
circumstances, the holders of the senior preferred stock are not entitled to
vote. The consent of holders of at least 66 2/3% of the outstanding shares of
the senior preferred stock (and any other series of preferred stock ranking on a
parity therewith), voting as a single class, is required to authorize another
class of shares senior to such preferred stock.

Equity Stock

     Public Storage is authorized to issue 200,000,000 shares of equity stock,
$.01 par value per share.  At March 15, 1999, Public Storage had 225,000
outstanding shares of equity stock which rank on a parity with the Public
Storage common stock.  Public Storage's articles of incorporation provide that
the equity stock may be issued from 

                                       61
<PAGE>
 
time to time in one or more series and give the Board of Directors broad
authority to fix the dividend and distribution rights, conversion and voting
rights, redemption provisions and liquidation rights of each series of equity
stock. Holders of equity stock have no preemptive rights. The shares of equity
stock will be, when issued, fully paid and nonassessable.

Effects of Issuance of Capital Stock

     The issuance of Public Storage common stock and the issuance of preferred
stock or equity stock with special voting rights could be used to deter attempts
by a single shareholder or group of shareholders to obtain control of Public
Storage in transactions not approved by Public Storage's Board of Directors.
Public Storage has no intention to issue Public Storage common stock or the
preferred stock or equity stock for such purposes.

                       FEDERAL INCOME TAX CONSIDERATIONS

     The following discussion summarizes the material federal income tax
considerations that are generally applicable to the public limited partners as a
result of the merger and as a result of the subsequent ownership and disposition
of shares of Public Storage common stock for limited partners that do not make a
cash election.  This discussion is not exhaustive of all possible tax
considerations and does not give a detailed description of any state, local, or
foreign tax considerations.  Nor does it discuss all of the aspects of federal
income taxation that may be relevant to a limited partner in light of his or her
particular circumstances or to certain types of limited partners who are subject
to special treatment under federal income tax laws (including insurance
companies, tax-exempt entities, financial institutions or broker-dealers,
foreign corporations and persons who are not citizens or residents of the United
States).

     This discussion is based on the Internal Revenue Code of 1986, as amended
(the "Code"), including the provisions of the IRS Restructuring and Reform Act
(the "1998 Reform Act"), the Taxpayer Relief Act of 1997 (the "1997 Act"),
applicable Treasury Regulations, judicial decisions, and Internal Revenue
Service ("IRS") rulings, certain factual assumptions related to the ownership
and operation of Public Storage and the Partnership and certain representations
made by Public Storage and the Partnership.  There can be no assurance that the
legal authorities on which this discussion is based will not change, perhaps
retroactively, that the factual assumptions underlying this discussion will be
accurate, or that there will not be a change in the circumstances of Public
Storage or the Partnership that would affect this discussion.  Neither the
Partnership nor Public Storage plans to obtain any rulings from the IRS
concerning tax issues with respect to the merger or the continued qualification
of Public Storage as a REIT.  Thus, no assurance can be provided that the
statements set forth in this discussion (which do not bind the IRS or the
courts) will not be challenged by the IRS or will be sustained if so challenged.

     Because this discussion does not deal with all aspects of federal taxation,
and the tax consequences will not be the same for all public limited partners,
public limited partners are urged to consult their own tax advisors with
specific reference to their own tax situations, including the application and
effect of federal, state, local, and foreign tax laws.

Opinion of Counsel

     A. Timothy Scott, tax counsel and senior vice president of Public Storage,
has reviewed the following discussion and is of the opinion that this discussion
fairly summarizes the material federal income tax considerations to the public
limited partners as a result of the merger and as a result of the subsequent
ownership of Public Storage common stock for limited partners that do not make a
cash election, and that Public Storage is organized and operated so as to meet
the requirements for qualification as a REIT.  As is noted below, Public
Storage's qualification and taxation as a REIT depends upon both Public
Storage's satisfaction in the past, and Public Storage's ability to meet on a
continuing basis in the future, through actual annual operating and other
results, the various requirements under the Code with regard to, among other
things, the sources of its gross income, the lack of "C" corporation earnings
and profits, the composition of its assets, the levels of distributions to
shareholders, and the diversity of its stock ownership.  Tax counsel has relied
upon representations of management with respect to these matters and has not
reviewed or audited, and will not review or audit, compliance with these
requirements and does not express an opinion about those representations.
Accordingly, no assurance can be given that the actual results of Public
Storage's operations, the sources of its income, the lack of "C" corporation
earnings and profits, the nature of its assets, the level of its distributions
to shareholders and the diversity of its share ownership for any given taxable
year have satisfied or will satisfy the requirements under the Code for
qualification and taxation as a REIT.  The opinion is not binding upon the IRS
or the courts, and there can be no assurance that the IRS would not seek to
assert a contrary position.  Also, there cannot be any assurance that future
legislative, judicial or administrative changes (which could be retroactive in
effect) will not adversely affect the conclusions reached in the opinion or the
discussion set forth below.  Finally, the opinion is expressly limited to the
specific conclusions described in the first sentence of this section and does
not purport to address any other federal, state, local or foreign tax
consequences that may result from the merger or any other transaction.

                                       63

The Merger

     The merger will be treated for federal income tax purposes as a taxable
sale of the Partnership Units held by public limited partners, both for limited
partners electing to receive cash and for those electing to receive Public
Storage common stock.  Taxable public limited partners will be taxed on the
difference between the adjusted basis of their units and the amount of cash
received or the fair market value of the Public Storage common stock received.
Public Storage estimates that taxable public limited partners who acquired their
units in the original offering will recognize a capital gain of approximately
$435 per unit as a result of the merger (assuming that the merger is effective
in the first quarter of 1999).  The particular tax consequences of the merger
for a public limited partner will depend upon a number of factors related to his
or her tax situation, including the tax basis of the limited partner's units and
the tax impact could be quite different for public limited partners who acquired
their units after the original offering.

     To the extent that a taxable public limited partner recognizes a capital
loss as a result of the merger, the loss generally can be applied to offset
capital gain from other sources.  Individuals may use capital losses in excess
of capital gains to offset up to $3,000 of ordinary income in any single year
($1,500 for a married individual filing a separate return).  Any capital losses
that are not used currently can be carried forward for use in subsequent years.
A corporation's capital losses in excess of current capital gains generally may
be carried back three years, with any remaining unused portion available to be
carried forward for five years.

     The merger is not expected to be a taxable event for Public Storage, which
will retain its existing interests in the Partnership and will be treated as
having purchased the interests of the public limited partners.

General Tax Treatment of Public Storage

     If certain detailed conditions imposed by the Code and the related Treasury
Regulations are met, an entity, such as Public Storage, that invests principally
in real estate and that otherwise would be taxed as a corporation may elect to
be treated as a REIT.  The most important consequence to Public Storage of being
treated as a REIT for federal income tax purposes is that this enables Public
Storage to deduct dividend distributions to its shareholders, thus effectively
eliminating the "double taxation" (at the corporate and shareholder levels) that
typically results when a corporation earns income and distributes that income to
shareholders in the form of dividends.

     Public Storage elected to be taxed as a REIT beginning with its fiscal year
ending December 31, 1981.  That election continues in effect until it is revoked
or terminated.  Public Storage believes that it has qualified since its
election, and currently qualifies, as a REIT, and Public Storage expects to
continue to be taxed as a REIT for federal income tax purposes.  While Public
Storage intends to operate so that it will continue to qualify as a REIT, given
the highly complex nature of the rules governing REITs, the ongoing importance
of factual determinations, and the possibility of future changes in the
circumstances of Public Storage, no assurance can be given that Public Storage
will so qualify for any particular year.

     Technical Requirements for Taxation as a REIT.  The following is a very
brief overview of certain of the technical requirements that Public Storage must
meet on an ongoing basis in order to continue to qualify as a REIT.  This
summary is qualified in its entirety by the applicable Code provisions, Treasury
Regulations, and administrative and judicial interpretations of those
provisions.

     The Code defines a REIT as a corporation, trust or association:  (1) that
is managed by one or more trustees or directors, (2) the beneficial ownership of
which is evidenced by transferable shares of stock, or by transferable
certificates of beneficial interest, (3) that would be taxable as a domestic
corporation, but for Sections 856 through 859 of the Code, (4) that is neither a
financial institution nor an insurance company subject to certain provisions of
the Code, (5) the beneficial ownership of which is held by 100 or more persons,
(6) that during the last half of each taxable year not more than 50% in value of
the outstanding stock of which is owned, directly or indirectly, by five or
fewer individuals (as defined in the Code to include certain entities and
applying certain ownership attribution rules)(the "5/50 Test"), and (7) that
meets certain other tests, described below, regarding the nature of its income
and assets and the amount of its distributions.

     Public Storage's articles of incorporation and bylaws contain restrictions
regarding the transfer of its capital stock that are intended to assist Public
Storage in continuing to satisfy the stock ownership requirements described in

                                       64
<PAGE>
 
conditions (5) and (6).  See "Description of Public Storage Capital Stock -
Ownership Limitations."  The ownership restrictions in Public Storage's articles
of incorporation and bylaws generally prohibit the actual or constructive
ownership of more than 2% of the outstanding shares of common stock (excluding
the interest held by the Hughes family) or more than 9.9% of the outstanding
shares of each class or series of shares of preferred stock or equity stock,
unless an exception is established by the Board of Directors.  The restrictions
provide that if, at any time, for any reason, those ownership limitations are
violated or more than 50% in value of Public Storage's outstanding stock
otherwise would be considered owned by five or fewer individuals, then a number
of shares of stock necessary to cure the violation will automatically and
irrevocably be transferred from the person causing the violation to a designated
charitable beneficiary.

     The ownership restrictions are modeled after certain arrangements that the
IRS has ruled in private letter rulings will preclude a REIT from being
considered to violate the REIT ownership tests so long as the arrangements are
enforceable as a matter of state law and the REIT seeks to enforce them as and
when necessary.  There can be no assurance, however, that the IRS might not seek
to take a different position with respect to Public Storage (a private letter
ruling is legally binding only with respect to the taxpayer to whom it was
issued and Public Storage has not obtained and will not seek a private ruling on
this issue) or contend that Public Storage failed to enforce these arrangements.

     Pursuant to the 1997 Act, for Public Storage's taxable years commencing on
or after January 1, 1998, if Public Storage complies with regulatory rules
pursuant to which it is required to send annual letters to holders of its
capital stock requesting information regarding the actual ownership of the
capital stock, and Public Storage does not know, or exercising reasonable
diligence would not have known, whether it failed to meet the 5/50 Test
(requirement (6) above), Public Storage will be treated as having met the 5/50
Test.  Public Storage believes that it has issued and outstanding sufficient
shares with sufficient diversity of ownership to allow it to satisfy the REIT
ownership requirements, and Public Storage intends to comply with the regulatory
rules to be issued pursuant to the 1997 Act.  See "- Consequences of the PSMI
Merger on Public Storage's Qualification as a REIT - Violation of Ownership
Requirements."

     A REIT is not allowed to have accumulated earnings and profits attributable
to non-REIT years.  A REIT has until the close of its first taxable year in
which it has non-REIT earnings and profits to distribute any such accumulated
earnings and profits.  In a corporate reorganization qualifying as a tax free
statutory merger (such as the PSMI Merger), the acquired corporation's current
and accumulated earnings and profits are carried over to the surviving
corporation.  Under Treasury Regulations, any non-REIT earnings and profits
treated as having been acquired by a REIT through such a merger will be treated
as accumulated earnings and profits of a REIT attributable to non-REIT years.
See "- Consequences of the PSMI Merger on Public Storage's Qualification as a
REIT - Elimination of Any Accumulated Earnings and Profits Attributable to Non-
REIT Years."

     Income Tests.  In order to maintain qualification as a REIT, Public Storage
must satisfy certain gross income requirements, which are applied on an annual
basis.  First, at least 75% of Public Storage's gross income (excluding gross
income from prohibited transactions) for each taxable year must be derived
directly or indirectly from investments relating to real property or mortgages
on real property (including "rents from real property" and, in certain
circumstances, interest) or from certain types of temporary investments.
Second, at least 95% of Public Storage's gross income (excluding gross income
from prohibited transactions) for each taxable year must be derived from the
same items which qualify under the 75% income test, and from dividends, interest
and gain from the sale or disposition of stock or securities, or from any
combination of the foregoing.  For taxable years ending on or before December
31, 1997, REITs were subject to a third gross income test providing that short-
term gain from the sale or other disposition of stock or securities, gain from
prohibited transactions and gain on the sale or other disposition of real
property held for less than four years (apart from involuntary conversions and
sales of foreclosure property) must have represented less than 30% of the REIT's
gross income (including gross income from prohibited transactions).  Pursuant to
the 1997 Act, Public Storage will not have to meet this 30% gross income test in
1998 and subsequent years.

     Rents received by Public Storage will qualify as "rents from real property"
in satisfying the gross income requirements described above only if several
conditions are met.  First, the amount of rent must not be based in whole or in
part on the income or profits of any person.  However, an amount received or
accrued generally will not be excluded from the term "rents from real property"
solely by reason of being based on a fixed percentage or 

                                       65
<PAGE>
 
percentages of receipts of sales. Public Storage anticipates that none of its
gross annual income will be attributable to rents that are based in whole or in
part on the income of any person (excluding rents based on a percentage of
receipts or sales, which, as described above, are permitted). Second, the Code
provides that rents received from a tenant will not qualify as "rents from real
property" if Public Storage, or an owner of 10% or more of Public Storage,
directly or constructively owns 10% or more of such tenant. Public Storage does
not anticipate that it will receive material amounts of income from such related
party tenants. Third, if rent attributable to personal property, leased in
connection with a lease of real property, is greater than 15% of the total rent
received under the lease, then the portion of rent attributable to such personal
property will not qualify as "rents from real property." Public Storage does not
anticipate deriving rent attributable to personal property leased in connection
with real property that exceeds 15% of the total rents. Finally, for rents
received to qualify as "rents from real property," Public Storage generally must
not operate or manage the property or furnish or render services to tenants,
other than through an "independent contractor" which is adequately compensated
and from whom Public Storage derives no revenue. The "independent contractor"
requirement, however, does not apply to the extent the services provided by
Public Storage are "usually or customarily rendered" in connection with the
rental of space for occupancy only and are not otherwise considered "rendered to
the occupant" ("Permissible Services"). Any services with respect to certain
properties that Public Storage believes may not be provided by Public Storage
directly without jeopardizing the qualification of rent as "rents from real
property" will be performed by "independent contractors."

     Pursuant to the 1997 Act, for Public Storage's taxable years commencing on
or after January 1, 1998, rents received generally will qualify as rents from
real property even if Public Storage were to provide services that are not
Permissible Services so long as the amount received for such "impermissible
services" meets a de minimis standard.  The amount received for impermissible
services with respect to a property will be de minimis so long as such amount
does not exceed one percent of all amounts received, directly or indirectly, by
Public Storage with respect to such property.  In computing any such amounts,
the amount that Public Storage would be deemed to have received for performing
impermissible services will be the greater of the actual amount so received or
150% of the direct cost to Public Storage of providing the impermissible
services.

     See "- Consequences of the PSMI Merger on Public Storage's Qualification as
a REIT - Nonqualifying Income," and "- Consequences of the PSMI Merger on Public
Storage's Qualification as a REIT - Acquisition of Affiliated Partnership
Interests" for a discussion of specific aspects of the PSMI Merger that may
affect Public Storage's ability to satisfy the 95% gross income test.  Public
Storage owns substantially all of the economic interest in PSPUD (the portable
self-storage business).  The income from that business would be nonqualifying
income to Public Storage and the business is conducted by a limited partnership
between Public Storage and a subsidiary of the Lock/Box Company.  The share of
gross income of that business attributable to Public Storage's partnership
interest, when combined with other nonqualifying income of Public Storage, must
be less than 5% of Public Storage's total gross revenues.  Public Storage
anticipates that it will be able to continue to satisfy both the 95% and 75%
gross income tests.

     If Public Storage fails to satisfy one or both of the 75% or 95% gross
income tests for any taxable year, it may nevertheless qualify as a REIT for
such year if qualifies for the "good cause" exception.  In order to qualify for
the "good cause" exception, Public Storage would have to satisfy each of the
following: (i) it reported the source and nature of each item of its gross
income in its federal income tax return for such year; (ii) the inclusion of any
incorrect information in its return is not due to fraud with intent to evade
tax; and (iii) the failure to meet such test is due to a reasonable cause and
not to willful neglect.  Public Storage intends to operate so that, in the event
it were to fail to meet the gross income tests, it would satisfy the "good
cause" exception.  It is not possible, however, to state whether in all
circumstances Public Storage would be entitled to the benefit of this relief
provision.  Even if the relief provision were to apply, Public Storage would be
subject to a 100% excise tax on the amount of the excess nonqualifying income
multiplied by a fraction, the numerator of which would be Public Storage's
taxable income (computed without its distribution deduction) and the denominator
of which would be Public Storage's gross income from all sources.  This excise
tax would have the general effect of causing Public Storage to pay all net
profits generated from this excess nonqualifying income to the IRS.

     Asset Tests.  Generally, to maintain REIT qualification, 75% of the value
of Public Storage's total assets must be represented by real estate, mortgages
secured by real estate, cash, or government securities (including its allocable
share of real estate assets held by any partnerships in which Public Storage
owns an interest).  Not more than 25% of Public Storage's total assets may be
represented by securities other than those in the 75% asset class.  Of the

                                       66
<PAGE>
 
investments included in the 25% asset class, the value of any one issuer's
securities owned by Public Storage may not exceed 5% of the value of Public
Storage's total assets, and Public Storage may not own more than 10% of any one
issuer's outstanding voting securities.  The 5% test generally must be met for
any quarter in which Public Storage acquires securities of an issuer.  Public
Storage believes that it satisfies these tests.  In this regard, however, the
value of Public Storage's interest in the Lock/Box Company (including the
Lock/Box Company's interest in PSPUD) may not exceed 5% of the value of Public
Storage's total assets and the 10% voting stock prohibition precludes Public
Storage from controlling the operations of the Lock/Box Company (in which Public
Storage owns 95% of the equity in the form of non-voting stock and the Hughes
family owns 5% of the equity but 100% of the voting stock), PSPUD (a subsidiary
of the Lock/Box Company) or PS Clearing Company, Inc. ("PSCC") (in which Public
Storage owns a less than 10% voting interest) and may preclude Public Storage
from exercising its rights of first refusal with respect to the corporations
owning the Canadian operations and the reinsurance business.

     See "- Recent Administration Proposal" for a discussion of a proposal that,
if enacted, would limit Public Storage's ability to derive economic benefits
from the activities of the Lock/Box Company and PSPUD.

     For purposes of applying the income and asset tests mentioned above, a REIT
is considered to own a proportionate share of the assets and to earn a
proportionate share of the income of any partnership in which it holds a
partnership interest.  See "- Consequences of the PSMI Merger on Public
Storage's Qualification as a REIT - Acquisition of Affiliated Partnership
Interests in the PSMI Merger."

     Annual Distribution Requirements.  In order to qualify as a REIT, Public
Storage must distribute to its shareholders in each taxable year an amount at
least equal to 95% of Public Storage's "REIT taxable income" (which is generally
equivalent to net taxable ordinary income).

     In years prior to 1990, Public Storage made distributions in excess of its
REIT taxable income.  During 1990, Public Storage reduced its distributions to
its shareholders.  As a result, distributions paid by Public Storage in 1990
were less than 95% of Public Storage's REIT taxable income for 1990.  Public
Storage has satisfied the REIT distribution requirements for 1990 through 1997
by attributing distributions in 1991 through 1998 to the prior year's taxable
income, and Public Storage expects to satisfy the distribution requirement for
1998 by attributing distributions in 1999 to its 1998 taxable income.  Public
Storage may be required, over each of the next several years, to make
distributions after the close of a taxable year and to attribute those
distributions to the prior year, but Public Storage shareholders will be treated
for federal income tax purposes as having received such distributions in the
taxable years in which they were actually made except for under certain
circumstances as described below under the heading "Taxation of Taxable Domestic
Holders of Public Storage Common Stock - Distributions by Public Storage."  The
extent to which Public Storage will be required to attribute distributions to
the prior year will depend on Public Storage's operating results and the level
of distributions as determined by Public Storage's Board of Directors.

     In addition, if Public Storage should fail to distribute during each
calendar year at least the sum of (i) 85% of its REIT ordinary income for such
calendar year, (ii) 95% of its REIT capital gain net income for such calendar
year, and (iii) any undistributed taxable income from prior periods, Public
Storage would be subject to a 4% excise tax on the excess of such required
distribution over the sum of amounts actually distributed during the calendar
year by the REIT and the amount, if any, on which the REIT paid income tax for
such year.

     Public Storage intends to make timely distributions sufficient to satisfy
its annual distribution requirements.  It is expected that Public Storage's REIT
taxable income will be less than its cash flow due to the allowance of
depreciation and other non-cash charges in computing REIT taxable income.
Accordingly, Public Storage anticipates that it will generally have sufficient
cash or liquid assets to enable it to satisfy the distribution requirements
described above.  It is possible, however, that Public Storage, from time to
time, may not have sufficient cash or other liquid assets to meet these
distribution requirements perhaps due to timing differences between (i) the
actual receipt of income and actual payment of deductible expenses and (ii) the
inclusion of such income and deduction of such expenses in arriving at taxable
income of Public Storage.  In such circumstances, in order to meet the
distribution requirements, Public Storage may find it necessary to arrange for
short-term, or possibly long-term, borrowings or to pay dividends in the form of
taxable stock dividends.

     Under certain circumstances, Public Storage may be able to rectify a
failure to meet the 95% distribution requirement for a year by paying
"deficiency dividends" to shareholders in a later year, which may be included in

                                       67
<PAGE>
 
Public Storage's deduction for dividends paid for the earlier year.  Thus,
Public Storage may be able to avoid being taxed on amounts distributed as
deficiency dividends; however, Public Storage will be required to pay interest
to the IRS based upon the amount of any deduction taken for deficiency
dividends.  See "- Consequences of the PSMI Merger on Public Storage's
Qualification as a REIT - Elimination of Any Accumulated Earnings and Profits
Attributable to Non-REIT Years."

     Applicable Federal Income Tax.  If Public Storage qualifies for taxation as
a REIT, Public Storage generally will not be subject to federal corporate income
taxes on net income that it distributes currently to shareholders.  However,
Public Storage will be subject to federal income tax in the following
circumstances.

       (1) Public Storage will be taxed at regular corporate rates on any
  undistributed REIT taxable income, including undistributed net capital gains.

       (2) Under certain circumstances, Public Storage may be subject to the
  "alternative minimum tax" on its items of tax preference.

       (3) If Public Storage has (i) net income from the sale or other
  disposition of "foreclosure property" (which is, in general, property acquired
  by foreclosure or otherwise on default of a lease or a loan secured by the
  property) that is held primarily for sale to customers in the ordinary course
  of business or (ii) other nonqualifying income from foreclosure property,
  Public Storage will be subject to tax at the highest corporate rate on such
  income.

       (4) If Public Storage has net income from prohibited transactions (which
  are, in general, certain sales or other dispositions of property (other than
  foreclosure property) held primarily for sale to customers in the ordinary
  course of business), such income will be subject to a 100% tax.

       (5) If Public Storage should fail to satisfy the 75% gross income test or
  the 95% gross income test (as discussed above), and has nonetheless maintained
  its qualification as a REIT because certain other requirements have been met,
  it will be subject to a 100% tax on the net income attributable to the greater
  of the amount by which Public Storage fails the 75% or 95% gross income test.

       (6) If Public Storage should fail to distribute during each calendar year
  at least the sum of (i) 85% of its REIT ordinary income for such year, (ii)
  95% of its REIT capital gain net income for such year, and (iii) any
  undistributed taxable income from prior periods, Public Storage would be
  subject to a 4% excise tax on the excess of such required distribution over
  the amounts actually distributed.

       (7) Under the "Built-in Gain Rules" of IRS Notice 88-19, 1988-1 C.B. 486,
  Public Storage generally will be subject to a corporate level tax if it
  disposes in a taxable transaction of any of the assets acquired from a C
  corporation (i.e., a corporation generally subject to full corporate level
  tax) in a transaction in which the basis of the asset in Public Storage's
  hands is determined by reference to the basis of the asset (or any other
  asset) in the hands of the C corporation, if the disposition occurs at any
  time during the 10-year period beginning on the date of the acquisition (the
  "Restriction Period").  This tax would be imposed pursuant to anticipated
  Treasury Regulations that have not yet been promulgated at the highest regular
  corporate rate (currently 35%) in effect at the time of the disposition on any
  "Built-in Gain" which represents the excess of (i) the lesser of (a) the fair
  market value at the time of the acquisition of the assets disposed of and (b)
  the selling price of such assets over (ii) Public Storage's adjusted basis in
  such assets at the time of the acquisition by Public Storage.  Public Storage
  made an election pursuant to IRS Notice 88-19 with respect to the PSMI Merger.
  Accordingly, Public Storage will be subject to a corporate level tax with
  respect to the assets acquired in the PSMI Merger only if it disposes of any
  Built-in Gain assets acquired in the PSMI Merger at any time during the
  applicable Restriction Period.  Public Storage currently does not intend to
  dispose any material portion of the assets acquired in the PSMI Merger during
  the Restriction Period, but there can be no assurance that one or more such
  dispositions will not occur.

     Failure to Qualify as a REIT.  For any taxable year that Public Storage
fails to qualify as a REIT and relief provisions do not apply, Public Storage
would be taxed at the regular corporate rates on all of its taxable income,
whether or not it makes any distributions to its shareholders.  Those taxes
would reduce the amount of cash available 

                                       68
<PAGE>
 
to Public Storage for distributions to its shareholders or for reinvestment. As
a result, failure of Public Storage to qualify as a REIT during any taxable year
could have a material adverse effect upon Public Storage and its shareholders.

     Termination of REIT Election.  Public Storage's election to be treated as a
REIT will terminate automatically if Public Storage fails to meet the REIT
qualification requirements described above.  If a termination (or a voluntary
revocation) occurs, unless certain relief provisions apply, Public Storage would
not be eligible to elect REIT status again until the fifth taxable year that
begins after the first year for which Public Storage's election was terminated
(or revoked).  If Public Storage loses its REIT status, but later qualifies and
elects to be taxed as a REIT again, Public Storage may face significant adverse
tax consequences.  Immediately prior to the effectiveness of the election to
return to REIT status, Public Storage would be treated as if it disposed of all
of its assets in a taxable transaction, triggering taxable gain with respect to
Public Storage's appreciated assets.  (Public Storage would, however, be
permitted to elect under Notice 88-19 to have any gains taken into account only
as and when they actually are recognized upon sales of the appreciated property
occurring within the 10-year Restriction Period after return to REIT status.)
Public Storage would not receive the benefit of a dividends paid deduction to
reduce any such taxable gains.  Thus, any such gains on appreciated assets would
be subject to double taxation, at the corporate as well as the shareholder
level.

Consequences of the PSMI Merger on Public Storage's Qualification as a REIT

     In light of the unique federal income tax requirements applicable to REITs,
Public Storage's continued qualification as a REIT could have been adversely
affected by the PSMI Merger, as discussed in greater detail below.

     Nonqualifying Income.  As described above, under the 95% gross income test,
Public Storage must derive at least 95% of its total gross income from specified
classes of income related to real property, dividends, interest or gains from
the sale or other disposition of stock or other securities that do not
constitute "dealer property."  After the PSMI Merger, Public Storage assumed
property management activities for entities in which Public Storage had an
interest, as well as for other entities in which Public Storage did not have an
interest.  Public Storage receives management fees from these owners in exchange
for the performance of the management activities, and the income generally is
treated as income not qualifying under the 95% test ("Nonqualifying Income").
See "- Acquisition of Affiliated Partnership Interests," discussing the
treatment of such income earned from partnerships in which Public Storage owns
an interest.

     In order to reduce the amount of Nonqualifying Income that otherwise might
have been recognized in 1996 (the year following the PSMI Merger), the owners of
certain properties pre-paid to Public Storage in December 1995 approximately
$4.5 million of management fees that Public Storage otherwise would have been
expected to receive for 1996, discounted to compensate for early payment.  At
the time, Public Storage received an opinion of outside tax counsel that it was
more likely than not that the IRS would respect the inclusion of the prepaid
management fees in the gross income of Public Storage when they were received,
although the opinion noted the existence of arguably contrary authorities.
There can be no assurance that the IRS might not assert that such management
fees should have been included in the gross income of Public Storage as the
related management services were provided in 1996, rather than being included in
the gross income when they were received in 1995.  If the IRS were to challenge
on this issue successfully, Public Storage's REIT status may have been
terminated unless Public Storage satisfied the "good cause" exception to the
income test.  There can be no assurance, however, that if Public Storage failed
to satisfy the 95% test, the IRS would necessarily agree that Public Storage had
operated in a manner that qualifies for the "good cause" exception.

     In connection with the PSMI Merger, Public Storage and the various other
owners of mini-warehouses and business parks for which Public Storage performs
management activities (the "Owners") entered into an agreement (the
"Administrative and Cost-Sharing Agreement") with PSCC pursuant to which PSCC
provides the Owners and Public Storage certain administrative and cost-sharing
services in connection with the operation of the properties and the performance
of certain administrative functions.  The services include the provision of
corporate office space and certain equipment, personnel required for the
operation and maintenance of the properties, and corporate or partnership
administration. Each of the Owners and Public Storage pay PSCC directly for
services rendered by PSCC in connection with the Administrative and Cost Sharing
Agreement. That payment is separate from and in addition to the compensation
paid to Public Storage under the management agreement for the management of the
properties 

                                       69
<PAGE>
 
owned by the Owners. Public Storage received a private letter ruling from the
IRS to the effect that the reimbursements and other payments made to PSCC by the
Owners will not be treated as revenues of Public Storage for purposes of the 95%
test.

     Violation of Ownership Requirements.  For Public Storage to qualify as a
REIT under the Code it must satisfy the 5/50 Test during the last half of each
taxable year: no more than 50% in value of its outstanding stock may be owned,
directly or constructively under the applicable attribution rules of the Code,
by five or fewer individuals (as defined in the Code to include certain
entities).  Following the PSMI Merger, the value of the outstanding capital
stock held by the Hughes family was estimated to be approximately 45% of the
value of all outstanding Public Storage stock (the Hughes family's interest has
subsequently come to represent less than 30% at October 1, 1998).  In order to
assist Public Storage in meeting these ownership restrictions, the Public
Storage articles of incorporation and bylaws generally prohibit the actual or
constructive ownership of more than 2.0% of the outstanding shares of all common
stock of Public Storage or more than 9.9% of the outstanding shares of each
class or series of shares of preferred stock of Public Storage, as was described
above.  (The Public Storage articles of incorporation and bylaws provide,
however, that no person is deemed to exceed this ownership limitation solely by
reason of the beneficial ownership of shares of any class of stock to the extent
that such shares of stock were beneficially owned by such person at the time of
the PSMI Merger.)

     However, even with these ownership limitations, a violation of the
ownership restrictions was still possible if four individuals unrelated to the
Hughes family were to own the maximum amount of capital stock permitted under
the Public Storage articles of incorporation.  Therefore, to further assist
Public Storage in meeting the ownership restrictions, the Hughes family at the
time of the PSMI Merger entered into an agreement with Public Storage for the
benefit of Public Storage and certain designated charitable beneficiaries
providing that if, at any time, for any reason, more than 50% in value of Public
Storage's outstanding stock otherwise would be considered owned by five or fewer
individuals, then a number of shares of Public Storage common stock owned by
Wayne Hughes necessary to cure such violation would automatically and
irrevocably be transferred to a designated charitable beneficiary.  These
provisions, like Public Storage's ownership limitations, were modeled after
certain arrangements that the IRS has ruled in private letter rulings will
preclude a REIT from being considered to violate the REIT ownership tests so
long as such arrangements are enforceable as a matter of state law and the REIT
seeks to enforce them as and when necessary.  There can be no assurance,
however, that the IRS would not seek to take a different position with respect
to Public Storage (a private letter ruling is legally binding only with respect
to the taxpayer to whom it was issued and Public Storage did not seek any such
ruling) or contend that Public Storage failed to enforce these various
arrangements and, as a result, there can be no assurance that these arrangements
necessarily preserve Public Storage's REIT status.

     Elimination of Any Accumulated Earnings and Profits Attributable to Non-
REIT Years.  As was noted earlier, a REIT is not allowed at the end of any
taxable year to have accumulated earnings and profits attributable to non-REIT
years.  In a corporate reorganization qualifying as a tax free statutory merger,
the acquired corporation's current and accumulated earnings and profits are
carried over to the surviving corporation.  Accordingly, any accumulated
earnings and profits of PSMI and its predecessors (including earnings and
profits resulting from transactions undertaken in contemplation of the PSMI
Merger or from the PSMI Merger itself) carried over to Public Storage in the
PSMI Merger and Public Storage would have been required to distribute any such
accumulated earnings and profits prior to the close of 1995 (the year in which
the PSMI Merger occurred).  Failure to do so would result in disqualification of
Public Storage as a REIT (unless the "deficiency dividend" procedures described
below apply and Public Storage complies with those procedures).

     The amount of any accumulated earnings and profits of PSMI acquired by
Public Storage was based on the consolidated earnings and profits of PSMI
(including each of its predecessors) through and including the date of the PSMI
Merger.  As a condition to the PSMI Merger, Public Storage received a study
prepared by PSMI of the earnings and profits of PSMI and its subsidiaries that
showed PSMI had no such consolidated accumulated earnings at the time of the
PSMI Merger.  The determination of the accumulated earnings and profits acquired
by Public Storage in the PSMI Merger ("Acquired Earnings") depends upon a number
of factual matters related to the activities and operations of PSMI and its
predecessors during their entire corporate existence and is subject to review
and challenge by the IRS.  There can be no assurance that the IRS will not
examine the tax returns of PSMI and its predecessors for years prior to and
including the PSMI Merger and propose adjustments that could increase the amount
of the Acquired Earnings.  

                                       70
<PAGE>
 
In this regard, the IRS can consider all taxable years of PSMI and its
predecessors as open for review for purposes of determining the amount of
earnings and profits.

     Although not free from doubt, it appears that pursuant to Treasury
Regulations Public Storage may be able to use certain "deficiency dividend"
procedures to distribute any Acquired Earnings that were subsequently determined
to exist as a result of an IRS audit.  In order to use this "deficiency
dividend" procedure, Public Storage would have to make an additional dividend
distribution to its shareholders (in addition to distributions made for purposes
of satisfying the normal REIT distribution requirements), within 90 days of the
IRS determination.  In addition, Public Storage would have to pay to the IRS an
interest charge on 50% of the Acquired Earnings that were not distributed prior
to December 31, 1995, from the date on which its 1995 tax return was due to the
date the IRS determination was made.  If such an issue were to be presented,
there can be no assurance that the IRS would not take the position either that
the "deficiency dividend" procedure is not available (in which case, Public
Storage would cease to qualify as a REIT effective for its taxable year in which
the PSMI Merger occurred) or, alternatively, that even if the procedure is
available, Public Storage cannot qualify as a REIT for the taxable year in which
the merger occurred (but it could qualify as a REIT for subsequent years).

     Acquisition of Affiliated Partnership Interests.  In the PSMI Merger and in
subsequent transactions, Public Storage has acquired interests in various
partnerships that own and operate properties.  Public Storage, for purposes of
satisfying the REIT asset and gross income tests, will be treated as if it
directly owns a proportionate share of each of the assets of these partnerships.
For these purposes, under current Treasury Regulations Public Storage's interest
in each of the partnerships must be determined in accordance with its "capital
interest" in such partnership.

     The ownership of these partnership interests creates several issues
regarding Public Storage's satisfaction of the 95% gross income test.  First,
Public Storage earns property management fees from these partnerships.  Existing
Treasury Regulations do not address the treatment of management fees derived by
a REIT from a partnership in which the REIT holds a partnership interest, but
the IRS has issued a number of private letter rulings holding that the portion
of the management fee that corresponds to the REIT's interest in the partnership
in effect is disregarded in applying the 95% gross income test where the REIT
holds a "substantial" interest in the partnership.  Public Storage disregards
the portion of management fees derived from partnerships in which it is a
partner that corresponds to its interest in these partnerships in determining
the amount of its Nonqualifying Income, and Public Storage's prepayment of
management fees set forth above was computed based upon this approach.  There
can be no assurance, however, that the IRS would not take a contrary position
with respect to Public Storage, either rejecting the approach set forth in the
private letter rulings mentioned above or contending that Public Storage's
situation is distinguishable from those addressed in the private letter rulings
(for example, because Public Storage does not have a "substantial" interest in
the partnerships).

     Second, Public Storage acquired interests in certain of these partnerships
that entitles Public Storage to a percentage of profits (either from operations,
or upon a sale, or both) in excess of the percentage of total capital originally
contributed to the partnership with respect to such interest.  Existing Treasury
Regulations do not specifically address this situation, and it is uncertain,
based on existing authority, how Public Storage's "capital interest" in these
partnerships should be determined.  This determination is relevant because it
affects both the percentage of the gross rental income of the partnership that
is considered gross rental income (or qualifying income) to Public Storage and
the percentage of the management fees paid to Public Storage that are
disregarded in determining Public Storage's Nonqualifying Income.  For example,
if Public Storage takes the position that it has a 25% "capital interest" in a
partnership (because it would receive 25% of the partnership's assets upon a
sale and liquidation) but the IRS determines it only has a 1% "capital interest"
(because the original holder of Public Storage's interest only contributed 1% of
the total capital contributed to the partnership), Public Storage's share of the
qualifying income from the partnership would be reduced and the portion of the
management fee from the partnership that would be treated as Nonqualifying
Income would be increased, thereby adversely affecting Public Storage's ability
to satisfy the 95% gross income test.  In determining its "capital interest" in
the various partnerships, Public Storage determines the percentage of the
partnership's assets that would be distributed to it if those assets were sold
and distributed among the partners in accordance with the applicable provisions
of the partnership agreements.  There can be no assurance, however, that the IRS
will agree with this methodology and not contend that another, perhaps less
favorable, method must be used for purposes of determining Public Storage
"capital interests," which could adversely affect Public Storage's ability to
satisfy the 95% gross income test.

Taxation of Taxable Domestic Holders of Public Storage Common Stock

     As used below, the term "U.S. Shareholder" means a holder of shares of
Public Storage common stock who (for United States federal income tax purposes):
(i) is a citizen or resident of the United States, (ii) is a corporation,
partnership, or other entity created or organized in or under the laws of the
United States or any political subdivision of the United States, (iii) is an
estate the income of which is subject to United States federal income taxation
regardless of its source or (iv) is a trust the administration of which is
subject to the primary supervision of a United States court and which has one or
more United States persons who have the authority to control all substantial
decisions of the trust.

     Distributions by Public Storage.  As long as Public Storage qualifies as a
REIT, distributions made to Public Storage's taxable U.S. Shareholders (and not
designated as capital gain dividends) will generally be taxable to such
shareholders as ordinary income to the extent of Public Storage's earnings and
profits.  Dividends declared during the last quarter of a calendar year and
actually paid during January of the immediately following calendar year
generally are treated as if received by the shareholders on December 31 of the
calendar year during which they were declared.

     Distributions designated by Public Storage as capital gain dividends
generally will be taxed as long-term capital gain to shareholders, to the extent
that the distributions do not exceed Public Storage's actual net capital gain
for the taxable year. Corporate shareholders may be required to treat up to 20%
of any such capital gain dividends as ordinary income. As described below in 
"- Recent Legislation," the 1997 Act changed significantly the taxation of 
capital gains by taxpayers who are individuals, estates, or trusts. On November
10, 1997, the IRS issued IRS Notice 97-64, which provides generally that a REIT
may classify portions of its designated capital-gain dividend as (i) a 20% rate
gain distribution (which would be taxed as long-term capital gain in the 20%
group), (ii) an unrecaptured Section 1250 gain distribution (which would be
taxed as long-term capital gain in the 25% group), or (iii) a 28% rate gain
distribution (which would be taxed as long-term capital gain in the 28% group).
If no designation is made, the entire designated capital gain dividend will be
treated as a 28% rate gain distribution. IRS Notice 97-64 provides that a REIT
must determine the maximum amounts that it may designate as 20% and 25% rate
capital gain dividends by performing the computation required by the Code as if
the REIT were an individual whose ordinary income were subject to a marginal tax
rate of at least 28%. The Notice has not been updated to reflect the provisions
of the 1998 Reform Act, which generally include capital gains (other than gains
in the 25% group) in the 20% group if the asset was held more than 12 months at
the time of sale. The Notice further provided that designations made by the REIT
will only be effective to the extent that they comply with Revenue Ruling 89-81,
which requires that distributions made to different classes of shares be
composed proportionately of dividends of a particular type.

     Shareholders may not include in their individual income tax returns any net
operating losses or capital losses of Public Storage.  Instead, such losses
would be carried over by Public Storage for potential offset against future
income (subject to certain limitations).  Distributions made by Public Storage
and gain arising from the sale or exchange by a U.S. Shareholder of Public
Storage common stock will not be treated as passive activity income, and, as a
result, shareholders generally will not be able to apply any "passive losses"
against such income or gain.  In addition, taxable distributions from Public
Storage will be treated as investment income for purposes of the investment
interest limitations.  Capital gain dividends and capital gains from the
disposition of shares (including distributions treated as such), however, will
be treated as investment income only if the U.S. Shareholder so elects, in which
case such capital gains will be taxed at ordinary income rates.  Public Storage
will notify shareholders after the close of its taxable year as to the portions
of the distributions attributable to that year that constitute ordinary income,
return of capital and capital gain.

     Distributions by Public Storage, whether characterized as ordinary income
or as capital gain, are not eligible for the 70% dividends received deduction
for corporations.  Future regulations may require that the shareholders take
into account, for purposes of computing their individual alternative minimum tax
liability, certain tax preference items of Public Storage.

     Public Storage may designate (by written notice to shareholders) its
retained net capital gain (i.e., net capital gain that is not actually
distributed as capital gain dividends, as described above) as undistributed
capital gains in respect of shareholders' shares.  Pursuant to such a
designation by Public Storage, a U.S. Shareholder would include its
proportionate share of such retained net capital gains in income as capital
gain, and would be treated as having paid its proportionate share of the tax
paid by the REIT with respect to the gain.  The U.S. Shareholder's basis in its

                                       72
<PAGE>
 
shares would be increased by its share of such gain and decreased by its share
of such tax.  With respect to such capital gain of a U.S. Shareholder that is an
individual or an estate or trust, the IRS has authority to issue regulations
that could apply the special tax rate applicable generally to the portion of the
long term capital gains of an individual or an estate or trust attributable to
deductions for depreciation taken with respect to depreciable real property.

     Public Storage may distribute cash in excess of its net taxable income.
Upon distribution of such cash by Public Storage to shareholders (other than as
a capital gain dividend), if all of Public Storage's current and accumulated
earnings and profits have been distributed, the excess cash will be deemed to be
a non-taxable return of capital to each U.S. Shareholder to the extent of the
adjusted tax basis of the shareholder's capital stock.  Distributions in excess
of the adjusted tax basis will be treated as gain from the sale or exchange of
the capital stock.  A U.S. Shareholder who has received a distribution in excess
of current and accumulated earnings and profits of Public Storage may, upon the
sale of the capital stock, realize a higher taxable gain or a smaller loss
because the basis of Public Storage common stock as reduced will be used for
purposes of computing the amount of the gain or loss.

     In any year in which Public Storage does not qualify as a REIT,
distributions by Public Storage to shareholders will be taxable in the same
manner discussed above, except that no distributions can be designated as
capital gain dividends, distributions will be eligible for the corporate
dividends received deduction, and shareholders will not receive any share of
Public Storage's tax preference items.

     Sales of Public Storage Common Stock.  In general, a U.S. Shareholder will
realize gain or loss upon the sale of Public Storage common stock equal to the
difference between (i) the amount of cash and the fair market value of any
property received on such disposition and (ii) the shareholder's adjusted basis
of such shares of Public Storage common stock.  With respect to dispositions
occurring on or after January 1, 1998, such gain or loss will be long-term
capital gain or loss if such shares have been held for more than one year.  If a
shareholder receives a long-term capital gain dividend from Public Storage and
has held the capital stock for six months or less, any loss incurred on the sale
or exchange of the capital stock is treated as a long-term capital loss, to the
extent of the corresponding long-term capital gain dividend received.

     Backup Withholding.  If a U.S. Shareholder is subject to "backup
withholding," Public Storage will be required to deduct and withhold a tax of
31% from any dividends payable to the shareholder.  These rules may apply when a
shareholder fails to supply a correct taxpayer identification number, or when
the IRS notifies Public Storage that the shareholder is subject to the rules or
has furnished an incorrect taxpayer identification number.

     Taxation of Tax Exempt Shareholders.  In general, a tax exempt entity that
is a U.S. Shareholder is not subject to tax on distributions from Public Storage
or gain realized on the sale of capital stock, provided that the tax exempt
entity has not financed the acquisition of its capital stock with "acquisition
indebtedness" within the meaning of the Code.  Special rules apply to
organizations exempt under Code Sections 501(c)(7), (c)(9), (c)(17) and (c)(20),
and such entities should consult their own tax advisors concerning the
applicable "set aside" and reserve requirements.  In addition, certain
distributions by a REIT to a tax-exempt employee's pension trust that owns more
than 10% of the REIT will, in certain circumstances, be treated as "unrelated
business taxable income."

Taxation of Non-U.S. Shareholders

     The rules governing U.S. federal income taxation of non-U.S. Shareholders
are complex, and the following discussion is intended only as a summary of
certain of those rules.  Non-U.S. shareholders should consult with their tax
advisors to determine the impact of U.S. federal, state, and local income tax
laws on an investment in Public Storage, including any reporting requirements,
as well as the tax treatment of such an investment under their home country
laws.

     Distributions by Public Storage.  Distributions to a non-U.S. Shareholder
will generally be subject to tax as ordinary income to the extent of Public
Storage's current or accumulated earnings and profits as determined for U.S.
federal income tax purposes.  Such distributions will generally be subject to
withholding of that income tax at a 30% rate, unless reduced by an applicable
tax treaty or unless the dividends are treated as effectively connected with a
United States trade or business.  Under currently applicable Treasury
regulations, withholding agents are required to determine the applicable
withholding rate pursuant to the appropriate tax treaty, and withhold the
appropriate amount.  New Treasury Regulations recently have been adopted that
revise in certain respects the rules applicable to non-U.S. 

                                       73
<PAGE>
 
Shareholders (the "New Regulations"). The New Regulations are generally
effective with respect to payments made after December 31, 1998 but the IRS has
announced that the New Regulations will be amended to be effective generally for
payments made after December 31, 1999, subject to certain transition rules.

     Currently, dividends paid to an address in a foreign country are presumed
to be paid to a resident of that country (unless the payor has knowledge to the
contrary) for purposes of the 30% U.S. withholding tax applicable to certain
non-U.S. Shareholders and for purposes of determining the applicability of a tax
treaty rate.  Under the New Regulations, however, a non-U.S. Shareholder who
wishes to claim the benefit of an applicable treaty rate will be required to
provide an IRS Form W-8 which satisfies applicable certification and other
requirements, including a representation as to the holder's foreign status, the
holder's name and permanent residence address, and the relevant tax treaty.
Such information is subject to being reported to the IRS.  A permanent residence
address for this purpose generally is the address in the country where the
person claims to be a resident for purposes of the country's income tax.  If the
beneficial holder is a corporation, then the address is where the corporation
maintains its principal office in its country of incorporation.  The New
Regulations also provide special rules to determine whether, for purposes of
determining the applicability of a tax treaty and for purposes of the 30%
withholding tax described above, dividends paid to a non-U.S. Shareholder that
is an entity should be treated as paid to the entity or those holding an
interest in that entity.  In particular, in the case of a foreign partnership,
the certification requirement will generally be applied to the partners of the
partnership.  In addition, the New Regulations will also require the partnership
to provide certain information, including a United States taxpayer
identification number, and will provide look-through rules for tiered
partnerships.  A non-U.S. Shareholder that is eligible for a reduced rate of
U.S. withholding tax pursuant to an income tax treaty may obtain a refund of any
excess amount withheld by filing an appropriate claim for refund with the IRS.

     If the amount distributed exceeds a non-U.S. Shareholder's allocable share
of current or accumulated earnings and profits, the excess will be treated as a
tax-free return of capital to the extent of such shareholder's adjusted basis in
the common stock.  To the extent that such distributions exceed the adjusted
basis of a non-U.S. Shareholder's common stock, such distributions will
generally be subject to tax if such shareholder would otherwise be subject to
tax on any gain from the sale or disposition of its common stock, as described
below.  Under current law, it appears that Public Storage will be required to
withhold 10% of any distribution to a non-U.S. Shareholder in excess of Public
Storage's current and accumulated earnings and profits.  Consequently, although
Public Storage intends to withhold at a rate of 30% on the entire amount of any
distribution to a non-U.S. Shareholder (or lower applicable treaty rate), to the
extent Public Storage does not do so, any portion of such a distribution not
subject to withholding at a rate of 30% (or lower applicable treaty rate) will
be subject to withholding at a rate of 10%.  However, the non-U.S. Shareholder
may seek a refund of such amounts from the IRS if it subsequently determined
that such distribution was, in fact, in excess of current or accumulated
earnings and profits of Public Storage, and the amount withheld exceeded the
non-U.S. Shareholder's United States tax liability, if any, with respect to the
distribution.  A Non-U.S. shareholder who is a shareholder of record and is
eligible for reduction or elimination of withholding must file an appropriate
form with Public Storage in order to claim such treatment.

     Distributions to a non-U.S. Shareholder that are designated by Public
Storage at the time of distribution as capital gains dividends (other than those
arising from the disposition of a United States real property interest)
generally will not be subject to United States federal income taxation, unless
(i) the investment in the common stock is effectively connected with the non-
U.S. Shareholder's United States trade or business, in which case the non-U.S.
Shareholder will be subject to the same treatment as domestic shareholders with
respect to such gain (except that a shareholder that is a foreign corporation
may also be subject to the 30% branch profits tax) or (ii) the non-U.S.
Shareholder is a nonresident alien individual who is present in the United
States for 183 days or more during the taxable year and certain other
requirements are met, in which case the nonresident alien individual will be
subject to a 30% tax on the individual's capital gains.

     Under the Foreign Investment in Real Property Tax Act ("FIRPTA"),
distributions to a non-U.S. Shareholder that are attributable to gain from sales
or exchanges by Public Storage of United States real property interests (whether
or not designated as a capital gain dividend) will be treated as income
effectively connected with a United States trade or business.  Non-U.S.
Shareholders would thus generally be taxed at the same rates applicable to
domestic shareholders (subject to a special alternative minimum tax in the case
of nonresident alien individuals).  Also, such gain may be subject to a 30%
branch profits tax in the hands of a non-U.S. Shareholder that is a corporation.
Public Storage is required to withhold 35% of any such distribution.  That
amount is creditable against the non-U.S. Shareholder's United States federal
income tax liability.

                                       74
<PAGE>
 
     Although the law is not entirely clear on the matter, it appears that
amounts designated by Public Storage pursuant to the 1997 Act as undistributed
capital gains in respect of shares of common stock (see "Taxation of Taxable
Domestic Holders of Common Stock" above) would be treated with respect to non-
U.S. Shareholders in the manner outlined in the preceding paragraph for actual
distributions by Public Storage of capital gain dividends.  Under that approach,
the non-U.S. Shareholders would be able to offset as a credit against their
United States federal income tax liability resulting therefrom their
proportionate share of the tax paid by Public Storage on such undistributed
capital gains (and to receive from the IRS a refund to the extent their
proportionate share of such tax paid by Public Storage were to exceed their
actual United States federal income tax liability).

     Sale of Common Stock.  Gain recognized by a non-U.S. Shareholder upon a
sale of its common stock will generally not be subject to tax under FIRPTA if
Public Storage is a "domestically controlled REIT," which is defined generally
as a REIT in which at all times during a specified testing period less than 50%
in value of its shares were held directly or indirectly by non-U.S. persons.
Because only a minority of Public Storage's shareholders are believed to be non-
U.S. Shareholders, Public Storage expects to qualify as a "domestically
controlled REIT." Accordingly, a non-U.S. Shareholder should not be subject to
U.S. tax from gains recognized upon disposition of the common stock, provided
that such gain is not effectively connected with the conduct of a United States
trade or business and, in the case of an individual shareholder, such holder is
not present in the United States for 183 days or more during the year of sale
and certain other requirements are met.

     Backup Withholding Tax and Information Reporting.  Public Storage must
report annually to the IRS and to each non-U.S. Shareholder the amount of
dividends (including any capital gain dividends) paid to, and the tax withheld
with respect to, each non-U.S. Shareholder.  These reporting requirements apply
regardless of whether withholding was reduced or eliminated by an applicable tax
treaty.  Copies of these returns may also be made available under the provisions
of a specific treaty or agreement with the tax authorities in the country in
which the non-U.S. Shareholder resides.

     The New Regulations also make certain changes in the new information
reporting and backup withholding rules for payments made after December 31,
1998.  As stated above, the IRS has announced its intention to amend the New
Regulations to extend the effective date to those payments made after December
31, 1999.  In general, the New Regulations do not significantly alter the
substantive backup withholding and information reporting requirements described
herein.  Shareholders should consult their tax advisors with respect to such
changes.

     Backup withholding tax (which generally is a withholding tax imposed at a
rate of 31% on certain payments to persons that fail to furnish certain
information under the United States information reporting requirements) and
information reporting will generally not apply to distributions paid to non-U.S.
Shareholders outside the United States that are treated as (i) dividends subject
to the 30% (or lower treaty rate) withholding tax discussed above, (ii) capital
gains dividends, or (iii) distributions attributable to gain from the sale or
exchange by Public Storage of United States real property interests.  As a
general matter, backup withholding and information reporting will not apply to a
payment of the proceeds of a sale of common stock by or through a foreign office
of a foreign broker.  Information reporting (but not backup withholding) will
apply, however, to a payment of the proceeds of a sale of common stock by a
foreign office of a broker that (a) is a United States person, (b) derives 50%
or more of its gross income for certain periods from the conduct of a trade or
business in the United States or (c) is a "controlled foreign corporation"
(generally a foreign corporation controlled by United States shareholders) for
United States tax purposes, unless the broker has documentary evidence in its
records that the holder is a non-U.S. Shareholder and certain other conditions
are met, or the shareholder otherwise establishes an exemption.  Payment to or
through a United States office of a broker of the proceeds of a sale of common
stock is subject to both backup withholding and information reporting unless the
shareholder certifies under penalty of perjury that the shareholder is a non-
U.S. Shareholder, or otherwise establishes an exemption.  A non-U.S. Shareholder
may obtain a refund of any amounts withheld under the backup withholding rules
by filing the appropriate claim for refund with the IRS.

Ownership Records

     To monitor Public Storage's compliance with the REIT share ownership
requirements, Public Storage is required to demand annual written statements
from the record holders of designated percentages of its capital stock
disclosing the actual owners of the capital stock and to maintain permanent
records showing the information it has 

                                       75
<PAGE>
 
received as to the actual ownership of such capital stock and a list of those
persons failing or refusing to comply with such demand.

Recent Legislation

     As described above, the 1997 Act contained certain changes to the REIT
qualification requirements and to the taxation of REITs.  The 1997 Act also
contained certain changes to the taxation of capital gains of individuals,
trusts and estates and further changes relating to capital gains were made by
the 1998 Reform Act.

     Capital Gain Rates.  Under the 1997 Act as modified by the 1998 Reform Act
beginning January 1, 1998, individuals, trusts and estates that hold certain
investments for more than one year may be taxed at a maximum long-term capital
gain rate of 20% on the sale or exchange of those investments.  The 1997 Act
also provides a maximum rate of 25% for "unrecaptured section 1250 gain" for
individuals, trusts and estates, special rules for "qualified 5 year gain," and
other changes to prior law.  The 1997 Act allows the IRS to prescribe
regulations on how the 1997 Act's new capital gain rates will apply to sales of
capital assets by "pass-through entities," including REITs and to sales of
interests in "pass-through entities."  For a discussion of new rules under the
1997 Act that apply to the taxation of distributions by Public Storage to its
shareholders that are designated by Public Storage as "capital gain dividends,"
see "- Taxation of Taxable Domestic Holders of Public Storage Common Stock
Distributions by Public Storage" above.  Shareholders are urged to consult with
their tax advisors with respect to the new rules contained in the 1997 Act and
the 1998 Reform Act.

     REIT Provisions.  In addition to the provisions discussed above, the 1997
Act contained a number of technical provisions that either (i) reduce the risk
that Public Storage will inadvertently cease to qualify as a REIT, or (ii)
provide additional flexibility with which Public Storage can meet the REIT
qualification requirements.  These provisions are effective for Public Storage's
taxable years commencing on or after January 1, 1998.

Recent Administration Proposal

     The administration's budget proposal announced on February 2, 1998 included
a proposal to amend the REIT asset tests with respect to non-qualified REIT
subsidiaries, such as the Lock/Box Company.  The proposal would require a REIT
to own no more than 10% of the vote or value of the outstanding stock of any
non-qualified REIT subsidiary.  Stock interests held by a REIT in existing non-
qualified REIT subsidiaries would be grandfathered, and therefore subject only
to the existing test that restricts a REIT from owning more than 10% of the
voting securities of an issuer (see "- General Tax Treatment of Public
Storage"), except that such grandfathered status would terminate if the non-
qualified REIT subsidiary engaged in a new trade or business or acquired
substantial new assets on or after the effective date of the proposal.  As a
result, if the legislation were enacted and the Lock/Box Company were to
commence new trade or business activities or acquire substantial new assets
after the effective date of the proposal, the Lock/Box Company would lose its
grandfathered status and Public Storage would be subject to the new 10% of the
vote or value limitation with respect to its ownership interest in the Lock/Box
Company (which Public Storage does not now satisfy).  Accordingly, the proposal,
if enacted, could materially impede Public Storage's ability to expand the
business activities of the Lock/Box Company or PSPUD and to engage in other
activities through non-qualified REIT subsidiaries without jeopardizing Public
Storage's REIT status.  This would limit Public Storage's ability to derive
economic benefit from engaging in activities which were related to Public
Storage's businesses, but which were not qualified REIT activities.

     A second proposed provision would tax immediately the built-in gains of C
corporations merging into REITs in tax-free reorganizations.  Under current law,
C corporations can defer and may be able to eliminate this tax.  Accordingly, if
enacted as currently drafted, this provision could impede Public Storage's
ability to acquire additional properties through mergers with C corporations.

                             STATE AND LOCAL TAXES

     The tax treatment of limited partners, Public Storage and Public Storage's
shareholders in states having taxing jurisdiction over them may differ from the
federal income tax treatment.  Accordingly, no discussion of state taxation of
limited partners, Public Storage or Public Storage's shareholders is provided
nor is any representation made as to the tax status of Public Storage in such
states.  All limited partners should consult their own tax advisors as to the
treatment under the respective state tax laws applicable to them.

                                 LEGAL OPINIONS

     David Goldberg, senior vice president and general counsel of Public
Storage, will deliver an opinion to the effect that the shares of Public Storage
common stock to be issued in the merger will be validly issued, fully paid and
nonassessable.  Mr. Goldberg owns 96,214 shares of Public Storage common stock
and 600 shares of Public Storage senior preferred stock and has options to
acquire an additional 166,167 shares of Public Storage common stock.  A. Timothy
Scott, senior vice president and tax counsel of Public Storage, has rendered an
opinion to the effect that the discussion under "Federal Income Tax
Considerations" fairly summarizes the material federal income tax considerations
to a limited partner as a result of the merger, and the subsequent ownership of
Public Storage common stock.  Mr. Scott owns 3,367 shares of Public Storage
common stock and has options to acquire an additional 60,000 shares of Public
Storage common stock.

                      AGREEMENT AND PLAN OF REORGANIZATION



     THIS AGREEMENT AND PLAN OF REORGANIZATION ("Agreement") is entered into as
of this 19th day of January, 1999, by and among PUBLIC STORAGE, INC., a
California corporation ("PSI"), PS Partners II Merger Co., Inc., a California
corporation ("Sub") and PS Partners II, Ltd., a California limited partnership
("PSP").

     A.  This Agreement provides for the merger of Sub, a wholly-owned, second
tier subsidiary of PSI, with and into PSP in accordance with the applicable
provisions of the California Revised Limited Partnership Act (the "CRLPA") and
the Certificate of Merger in the form prescribed by the California Secretary of
State as provided in Section 15678.4 of the CRLPA (the "Certificate of Merger").

     B.  The Board of Directors of PSI and the general partners of PSP believe
that it is in the best interests of PSI and PSP 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), Sub will be merged with and into PSP (the "Merger") in accordance with
the terms, conditions and provisions of this Agreement and the Certificate of
Merger.  The Merger shall become effective at the time at which the Certificate
of Merger is filed with the California Secretary of State in accordance with the
CRLPA, except that if the Certificate of Merger specifies a date subsequent to
the date of such filing on which the Merger is to become effective, the Merger
shall be effective on such specified subsequent date (the "Effective Time").
Sub and PSP are sometimes collectively referred to herein as the "Constituent
Entities" and PSP, as the surviving entity in the Merger, is sometimes referred
to herein as the "Surviving Entity."

         2.2 Effect of the Merger.  At the Effective Time:

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

          2.2.2     Partnership Agreement.  The partnership agreement of PSP in
effect at the Effective Time shall continue in full force and effect until
amended or terminated as provided in such partnership agreement or as provided
by law.

          2.2.3     General Partners.  The general partners of PSP shall remain
as its general partners with the same interests in PSP that they owned at the
Effective Time.

         2.3 Conversion of Partnership Units.  The manner of converting the
outstanding units of limited partnership interest of PSP (the "Units") 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, each Unit 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 Units") shall be converted into and shall represent
the right to receive $697 in cash (the "Cash Election Price").  As soon as
practicable after the Effective Time, the registered holders of Cash Election
Units shall be paid the cash to which they are entitled hereunder in respect of
such Cash Election Units.

          2.3.2     Share Exchange.  At the Effective Time, subject to Sections
2.4 and 2.5 hereof, each Unit (other than Cash Election Units and Units owned by
the parent of Sub) shall be converted into that number of PSI Shares equal to,
rounded to the nearest thousandth, the quotient (the "Conversion Number")
derived by dividing $697 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 Effective
Time.  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 Units who would
otherwise be entitled to such fractional share will 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
Information Statement provided for in Section 6.5 hereof, PSI will send to each
holder of record of Units 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 Units.  Any such
election to receive the cash payment contemplated by Section 2.3.1 hereof shall
have been properly made only if BankBoston, N.A. (the "Exchange Agent") shall
have received at its designated office, by 5:00 p.m., New York time, on the last
business day preceding the Effective Time, a Form of Election properly
completed, as set forth in such Form of Election.  Any Form of Election may be
revoked by the person submitting the same to the Exchange Agent only by written
notice received by the Exchange Agent prior to 5:00 p.m., New York time, on the
last business day before the Effective Time.  In addition, all Forms of Election
shall automatically be revoked if the Exchange Agent is notified in writing by
the parties hereto that the Merger have been abandoned.  The Exchange Agent 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 Exchange Agent determines that any election to
receive cash was not properly or timely made, the Units covered thereby shall
not be treated as Cash Election Units, and shall be converted in the Merger as
provided in Section 2.3.2 hereof.  The Exchange Agent may, with the agreement of
PSI and PSP, establish such procedures, not inconsistent with this Section 2.5,
as may be necessary or desirable to implement this Section 2.5.

         2.6 Conversion of Shares.  At the Effective Time, the shares of capital
stock of Sub shall be converted into an aggregate of 128,000 Units.

         2.7 Cancellation of Units Owned by Parent of Sub.  At the Effective
Time, any Units owned by the parent of Sub (other than Units acquired pursuant
to Section 2.6 hereof) shall be cancelled and retired and no shares shall be
issuable, and no cash shall be exchangeable, with respect thereto.

any person relating to an Acquisition Proposal; provided, however, that PSP's
general partners 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 general
partners of PSP to breach their fiduciary duty to the limited partners of PSP
under applicable law as advised by counsel.  PSP will

                                      A-6

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 PSP, and will keep PSI informed of the
status and terms of any such proposals and any such negotiations or discussions.

         6.5 Registration and Information Statement.  PSP will promptly prepare
and file with the SEC a preliminary information statement and notice of action
without a meeting in connection with the approval of the Merger by the limited

containing an information statement, notice of action without a meeting and
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 Units in the Merger (such information statement, notice of action
without a meeting and prospectus, together with any amendments thereof or
supplements thereto, in each case in the form or forms to be mailed to the
limited partners of PSP, being herein called the "Information Statement").  PSI
and PSP 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 PSP will use its best efforts to cause the Information Statement to be
mailed to its limited partners at the earliest practicable date.  PSP agrees
that if at any time prior to the Effective Time any event with respect to PSP
should occur which is required to be described in an amendment of, or a
supplement to, the Information Statement 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 limited partners
of PSP and (ii) the Information Statement will (with respect to PSP) 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 Information Statement 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 limited partners of PSP and (ii) the Information Statement
will (with respect to PSI) comply as to form in all material respects with the
requirements of the federal securities laws.

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.  PSP will not, at any time prior to the Effective
Time, declare or pay any cash distributions to its limited partners, except (i)
regular quarterly distributions at a quarterly rate not in excess of $8.36 per
Unit and (ii) distributions to limited partners of record immediately prior to
the Effective Time in an aggregate amount equal to the amount by which the
estimated Net Asset Value of PSP (as defined below) as of the Effective Time
exceeds $697 per Unit.  For this purpose, the Net Asset Value of PSP is the sum
of (a) the fair market value of PSP's real estate assets as determined by
appraisal by Charles R. Wilson & Associates, Inc. as of November 30, 1998, (b)
the book value of PSP's non-real estate assets (excluding marketable securities)
as of the date of determination and (c) the fair value of PSP's partnership
interests in PS Business Parks, L.P. based on the average of the per share
closing prices on the American Stock Exchange of the shares of common stock of
PS Business Parks, Inc. during the 20 consecutive trading days ending on the
fifth trading day prior to the Effective Time and less (d) PSP's liabilities as
of the date of determination.  The determination of book value and liabilities
shall be from PSP's financial statements prepared in accordance with generally
accepted accounting principles on a basis consistent with prior periods.

         8.4 Termination by PSP.  This Agreement may be terminated by PSP and
the Merger may be abandoned at any time prior to the Effective Time, before or
after limited partner approval, if (i) PSI shall have failed to comply in any
material respect with any of the covenants, conditions or agreements contained
in this Agreement to be complied with or performed by PSI at or prior to such
date of termination, which failure to comply has not been

                                      A-9
<PAGE>
 
cured within five business days following notice to PSI of such failure to
comply, or (ii) any representation or warranty of PSI contained in this
Agreement shall not be true in all material respects when made, which inaccuracy
or beach (if capable of cure) has not been cured within five business days
following notice to PSI of the inaccuracy or breach, or on and as of the Closing
as if made on and as of the Closing Date.

         8.5 Effect of Termination and Abandonment.  In the event of termination
of this Agreement and abandonment of the Merger pursuant to this Section 8, no
party (or any directors, officers, employees, agents or representatives of any
party) shall have any liability or further obligation to any other party or any
person who controls a party within the meaning of the Securities Act, except as
provided in Section 9.1 and except that nothing herein will relieve any party
from liability for any breach of this Agreement.

     9.  Miscellaneous.

         9.1 Payment of Expenses.  If the Merger is consummated, PSI shall pay
all the expenses incident to preparing for, entering into and carrying out this
Agreement and the consummation of the transactions contemplated hereby.  If the
Merger is not consummated, each of PSI and PSP shall pay its own expenses,
except that any expenses incurred in connection with the printing of the S-4

terminated and extinguished by the effectiveness of the Merger and shall not
survive the Effective Time.  The sole right and remedy arising from a
misrepresentation or breach of warranty, or from the failure of any of the

parties, which by its terms contemplates performance after the Effective Time.

         9.3 Modification or Amendment.  The parties may modify or amend this
Agreement by written agreement authorized by the Board of Directors of PSI and

Merger or this Agreement, without the approval of such limited partners.

         9.4 Waiver of Conditions.  The conditions to each of the parties'

Gentlemen:

According to your request and authorization, we have prepared a limited
appraisal of the above-referenced portfolio described in the attached document,
entitled Property Identification and Classification, and formed an opinion of
their Fee Simple and Leased Fee Market Value.  The accompanying appraisal
report, of which this letter is a part, briefly describes each property and
method of appraisal.

This report is presented in a restricted format and cannot be fully understood
without additional information supporting the appraisal, which has been retained
in the working files of the appraiser.

PURPOSE OF APPRAISAL
- --------------------

The purpose of the appraisal is to estimate the aggregate market value of the
portfolio in connection with a proposed merger of Public Storage Partners II,
Ltd. (PS Partners II) with a subsidiary of Public Storage, Inc. (PSI).

This report, presented in a restricted format, is intended for use only by the
clients or their advisors.  It may be referred to in solicitation materials and
distributed to the partners of PS Partners II, in connection with the proposed
merger.
<PAGE>
 
SCOPE OF ASSIGNMENT
- -------------------

The accompanying report describes the appraisal process undertaken.  In
accordance with our agreement, the scope of this assignment has been limited, as
described herein, but is in conformity with the Departure Provision of Uniform
Standards of Professional Appraisal Practice (USPAP).  The client must consider
that the value may be impacted to the degree there is a departure from specific
USPAP Guidelines.  However, this valuation analysis has utilized the two most
appropriate approaches to value.  We did not consider the Cost Approach to be
applicable.  Based upon our contact with knowledgeable self-storage investors,
owners, and managers, little reliance is placed upon the Cost Approach,
particularly as to properties the age and type of those included in the
portfolio.  Therefore, we have employed both the Income and Sales Comparison
Approaches.  We have relied most heavily on the Income Approach that is
supported by actual market data found in the Sales Comparison Approach.  In our
opinion, we have performed all actions necessary to ensure an accurate valuation
of the portfolio.

Your attention is directed to the Assumptions and Limiting Conditions and
description of the appraisal process set forth on the accompanying pages that
are an integral part of our report.  Only the summary conclusions are presented
in this report.

VALUE CONCLUSIONS
- -----------------

Aggregate Market Value

The market value estimate set forth herein is a gross value estimate and does
not include either a premium or a discount a potential buyer may assign to a
portfolio of properties as a result of its size.  Based on our experience with
buyers and sellers of properties the size and type included in the portfolio, it
would be inappropriate to assign either a premium or discount.  Furthermore, the
market value estimate herein assumes that the properties would be disposed of in
an orderly manner, allowing sufficient time for exposure of each property on the
open market.

Based upon the analysis made, it is our opinion that the Fee Simple and Leased
Fee Market Value of the Portfolio, as of November 30, 1998, is:

                          NINETY FOUR MILLION DOLLARS

                                 ($94,000,000)

                                        

Sincerely,
CHARLES R. WILSON & ASSOCIATES, INC.

Purpose, Function, and Scope of the appraisal

The purpose of this appraisal is to estimate the Fee Simple and Leased Fee
Market Value of the portfolio and to present a summary of conclusions.

The function of this appraisal is for use only by our clients, PS Partners II,
Ltd. and PSI, and their advisors in connection with the proposed merger of PS
Partners II, Ltd. with a subsidiary of PSI.
<PAGE>
 
The scope of this assignment is in accordance with an agreement between Charles
R. Wilson & Associates, Inc., and PS Partners II, Ltd.   In connection with this
portfolio valuation, the following actions have been taken as described more
fully in the section entitled Valuation Methodology.

    .  Inspections of each property were conducted by Charles R. Wilson, MAI,
       CRE, or a representative of Charles R. Wilson & Associates, Inc.

    .  Physical descriptive information was provided by the subject's on-site
       managers and from previous appraisals of the subject properties performed
       by Charles R. Wilson & Associates, Inc.

    .  Demographic information for each property's three mile radius including
       population trends, household income, employment, average housing prices,
       and rental rates was obtained from Scan/US Inc.

    .  Rental surveys of competitive facilities were provided by the on-site
       managers of the subject facilities. The information was verified by phone
       calls and other sources.

    .  Self Storage data Services, Inc. (SSDS), an affiliate company of Charles
       R. Wilson & Associates, Inc., provided operating income and expense
       information on facilities from its nationwide database of over 23,000
       self-storage facilities.

    .  Historical income and expense information on each of the subject
       properties was provided by PSI and the property managers, and compared to
       the operating information found in the SSDS database.

    .  In the cash flow analysis, the actual operating history of each of the
       subject properties was evaluated based on the experience of Charles R.
       Wilson & Associates, Inc., which has appraised over 300 self-storage
       facilities during the past 12 months.

    .  Discount rates, capitalization rates, and growth rates for income and
       expenses were derived from data on actual sales of similar properties,
       surveys of self-storage operator/investors throughout the United States,
       and our market experience over the past 20 years. Surveying self-storage
       investor's criteria is an ongoing function of Charles R. Wilson &
       Associates, Inc. In addition, specific individual and multiple-property
       transactions involving Public Storage, Inc., which are currently under
       contract or consummated within the past 12 months, were reviewed.

    .  The Sales Comparison Approach of the self-storage facilities is based on
       64 sales of self-storage facilities that occurred between October, 1997
       and September 1998.

Property Rights Appraised

The property rights appraised consist of the Fee Simple and Leased Fee Estates.
Due to the short-term, month-to-month tenancies, and the fact that rents are at
market levels, a Fee Simple Interest is appropriate for self-storage facilities.

According to the Appraisal Institute, Dictionary of Real Estate Appraisal, 3rd
                                      ----------------------------------------
Edition, 1993.
- -------       


     "Fee Simple Estate" is defined on page 140 as:  "Absolute ownership
     unencumbered by any other interest or estate; subject only to the
     limitations of governmental powers of taxation, eminent domain, police
     power, and escheat."

     "Leased Fee Estate" is defined on page 140 as:  "An ownership interest held
     by a landlord with the rights of use and occupancy conveyed by lease to
     others."

Market Value Definition

The following Market Value definition is based on Uniform Standards of
Professional Appraisal Practice regulations and standards.

"Market Value" means the most probable price that a property should bring in a
competitive and open market under all conditions requisite to a fair sale, the
buyer and seller each acting prudently and knowledgeably, and assuming the price
is not affected by undue stimulus.  Implicit in this definition is the
consummation of a sale as of a specified date and the passing of title from
seller to buyer under conditions whereby:

     1. Buyer and seller are typically motivated;
 
     2. Buyer and seller are well informed or well advised, and acting in what
        they consider their own best interest;
 
     3. A reasonable time is allowed for exposure on the open market;

     4. Payment is made in cash in U.S. dollars or in terms of financial
        arrangements comparable thereto; and

     5. The price represents the normal consideration for the property sold
        unaffected by special or creative financing or sale concessions granted
        by anyone associated with the sale.

VALUATION METHODOLOGY

Analysis and Valuation of the subject properties involved determining the
highest and best use of the sites, estimating the value of the subjects by
current appraisal theory, and reconciling to a final estimate of value.

The term "highest and best use," as used in this report, is defined as follows:
"The reasonably probable and legal use of vacant land or an improved property,
which is physically possible, appropriately supported, financially feasible, and
that results in the highest value."

     Source:  Appraisal Institute, The dictionary of Real Estate Appraisal, 3rd
                                   --------------------------------------------
     Edition, 1993, P.171.
     -------              

In considering the highest and best use of the properties in this portfolio, we
believe that each facility is producing net operating income in excess of a
reasonable land value.  Therefore, we have concluded that the Highest and Best
Use of each property, as improved and as if vacant, is its existing use as a
self-storage facility.  No other use would warrant their removal or alteration
from their current and intended use.

This valuation analysis has considered all appropriate approaches to value,
namely: the Cost, Income, and Sales Comparison Approaches.

The Cost Approach is based upon the proposition that the informed purchaser
would pay no more than the cost of producing a substitute property with the same
utility as the subject property.  The Cost Approach is particularly applicable
when the property being appraised involves relatively new improvements, which
represent the highest and best use of the land, and when relatively unique or
specialized improvements are located on the site and for which there exists no
comparable properties in the marketplace.

The Income Capitalization Approach is a procedure in appraisal analysis that
converts the anticipated benefits (dollar income or amenities) to be derived
from the ownership of property into a value estimate.  The Income Capitalization
Approach is widely applied in appraising income-producing properties.
Anticipated future income and/or reversions are discounted to a present worth
figure through the capitalization process.
<PAGE>
 
The Sales Comparison Approach is based upon the principle that an informed
purchaser would pay no more for a property than the cost of acquiring an
existing property with the same utility.  This approach is applicable when an
active market provides sufficient quantities of reliable data that can be
verified from authoritative sources.  The Sale Comparison Approach is relatively
unreliable in an inactive market or in estimating the value of properties for
which no real comparable sales data is available.

In all instances, we considered the Income and Sales Comparison Approaches to be
most applicable for the subject properties.  Based on our contact with property
buyers and sellers and others knowledgeable of recent transactions, today's
investors do not rely on the Cost Approach, particularly as to properties the
age and type of those included in the portfolio.  Therefore, we have employed
both the Income and Sales Comparison Approaches to value the facilities

Inspections were made of each property and interviews with property management
personnel were conducted to learn of any deferred maintenance items that need
correcting, as well as general information of the overall condition of the
property.  Questionnaires were completed by each on-site manager concerning
performance of the subject property and market competitors, rental surveys of
competitive properties were also reviewed and verified by telephone and other
sources.  Demographic information on each market was reviewed to gain insight
about local economic trends. Consideration has been given to significant
variations in quality among the various portfolio of properties including:
property income potential, quality of location and construction, tenant appeal,
access, viability, and potential competition.

Valuation Analysis

Income Approach
- ---------------

The Income Approach utilized the yield capitalization method.  The analysis was
premised upon a survey of competitive properties in order to determine market
rental rates, occupancy, and expense levels.

In addition, we reviewed each property's previous four-year operating statement.
Ancillary income included late fees and administrative fees.  Rental concessions
if any were analyzed and taken into consideration.  Utilizing the SSDS database
of operating statistics, the actual operating experience of self-storage
facilities in each subject's market area were compared to the subjects' actual
expenses to determine the reasonableness of each item of expense.  Stabilized
levels of income and expenses were determined.

In applying yield capitalization, we studied acquisition criteria of investors
in self-storage, and analyzed recent sales for valuation indicators such as
overall capitalization rates, effective gross rent multipliers, and prices being
paid per square foot.  We also consulted published sources of investment
criteria for other types of real estate.

In our Yield Capitalization Analysis, we prepared a ten-year discounted cash
flow of each of the self-storage facilities ending in 2008.  Using the
investment criteria discussed above, the income and expenses were increased 3%
to 3.5% annually based on local market conditions.  Real estate taxes for the
California properties are based on a sale and reassessment as of the date of
value and increased at 2% per annum, per California law.  The residual value was
determined by capitalizing the eleventh year income at a terminal capitalization
rate between 10.25% and 10.5% and then deducting 3% for sales costs.  The yearly
cash flows and the properties' residual values were discounted to present worth
using a discount rate between 12.75% and 13.25%

The indicated value of the portfolio based upon the Income Approach is 
$92,620,000.

Sales Comparison Approach
- -------------------------

In the Sales Comparison Approach, we relied most heavily upon an analysis of 64
sales of self-storage properties that occurred during the 12 month period
between October, 1997 and September, 1998.  The sales were analyzed on the basis
of effective gross rent multipliers, overall capitalization rates, and sales
price per square foot of net rentable area. A regression analysis of the
relationship between net operating income and sales price per square foot 
<PAGE>
 
was prepared. The value conclusion derived in the Income Approach was compared
to the conclusions derived from the Sales Comparison Approach to determine the
reasonableness of the value conclusion by the Income Approach. Differences in
time of sale, location, and physical characteristics between the sale
comparables and each subject property were taken into consideration.

Based upon the portfolio's net income per square foot, using the regression
analysis, the indicated value of the portfolio ranged between $76,940,000 and
$102,590,000.  As a reasonableness test, the resultant property and portfolio
capitalization rates were compared to reported capitalization rates of recent
transactions of self-storage property portfolios, some of which involved Public
Storage Inc., as a party to the transactions.

Value Conclusion
- ----------------

Although the departure provision has been invoked, it is our opinion that we
have performed actions necessary to develop an opinion as to the market value of
the portfolio.

The value conclusion from the Income and Sales Comparison Approaches was
reconciled into our final value conclusion of  $94,000,000.  In the final
analysis, both Income and Sales Comparison Approaches were considered, but most
reliance was placed upon the Income Approach.  This is the methodology employed
by today's investors in self-storage.

GENERAL ASSUMPTIONS & LIMITING CONDITIONS

Standards Rule (SR) 2-1 of the "Standards of Professional Practice" of the
Appraisal Institute requires the appraiser to "clearly and accurately disclose
any extraordinary assumption or limiting condition that directly affects an
appraisal analysis, opinion, or conclusion."  In compliance with SR 2-1, and to
assist the reader in interpreting this report, such assumptions and limiting
conditions are set forth as follows:

     1.  The date of value to which the conclusions and opinions expressed in
         this report apply is set forth in the letter of transmittal. Further,
         the dollar amount of any value opinion rendered in this report is based
         upon the purchasing power of the American dollar existing on that date.

     2.  The appraiser assumes no responsibility for economic or physical
         factors that may affect the opinions in the report which occur after
         the date of the letter transmitting the report.

     3.  Forecasts of anticipated revenue and expenses were based on our
         analysis of market trends, economic conditions, and historical
         operating results of the properties. Such forecasts are dependent on
         assumptions as to future economic, social and political conditions, as
         well as market related activity. They represent our opinion of current
         investor attributes and motivations applicable to the class of property
         appraised, and no warranty or representation that these forecasts will
         materialize is implied.

     4.  To the best of our knowledge the data set forth in this report and
         utilized in this appraisal is true and accurate. The information
         furnished by others is believed to be reliable; however, no warranty is
         given for its accuracy.

     5.  No opinion as to title is rendered. Data related to ownership and legal
         description was obtained from public records and is considered
         reliable. Title is assumed to be marketable and free and clear of all
         liens, encumbrances, easements, and restrictions except those
         specifically discussed in the report. The properties are appraised
         assuming they will be under responsible ownership and competent
         management, and available for their highest and best use.

     6.  The appraiser reserves the right to make such adjustments to the
         analyses, opinions, and conclusions set forth in this report as may be
         required by consideration of additional data or more reliable data that
         may become available.

     7.  The appraiser assumes no responsibility for hidden or unapparent
         conditions of the properties, subsoil, or structures that render them
         more or less valuable. No responsibility is assumed for arranging for
         engineering studies that may be required to discover them.
 
     8.  The properties are appraised assuming that all applicable zoning and
         use regulations and restrictions have been complied with, unless
         otherwise stated.

     9.  The properties are appraised assuming that all required licenses,
         certificates of occupancy, consents, or other legislative or
         administrative authority from any local, state, or national government
         or private entity or organization have been, or can be, obtained or
         renewed for any use on which the value estimate contained in this
         report is based, unless otherwise stated.

     10. No engineering survey has been made by the appraiser. Except as
         specifically stated, data relative to size and area was taken from
         sources considered reliable, and no encroachment of real property
         improvements is considered to exist.

     11. No soil tests or environmental studies were reviewed. The appraised
         value assumes that there are no sub-surface, toxic waste, or building
         material hazards in or on the properties that would adversely affect
         their existing or potential use.
<PAGE>
 
     12. Unless specifically stated, this appraisal does not take into
         consideration the possibility of the existence of asbestos, PCB
         transformer, or other toxic, hazardous, or contaminated substances
         and/or underground storage tanks (hazardous material), or the cost of
         encapsulation or removing thereof.

     13. No opinion is expressed as to the value of subsurface oil, gas, or
         mineral rights or whether the properties are subject to surface entry
         for the exploration or removal of such material except as is expressly
         stated.

     14. Maps, plats, and exhibits included in this report are for illustration
         only as an aid in visualizing matters discussed within the report. They
         should not be considered as surveys or relied upon for any other
         purpose, nor should they be removed from, reproduced, or used apart
         from this report.

     15. No opinion is intended to be expressed for matters that require legal
         expertise or specialized investigation or knowledge beyond that
         customarily employed by real estate appraisers.

     16. Except as consented to in the letter of transmittal, possession of this
         report, or a copy of it, does not carry with it the right of
         publication. It may not be used for any purpose by any person other
         than the party to whom it is addressed or it's financial advisors
         without the written consent of the appraiser and in any event only with
         proper written qualification and only in its entirety.

     17. Testimony of attendance in court or at any other hearing is not
         required by reason of rendering this appraisal, unless such
         arrangements are made a reasonable time in advance relative to such
         additional employment.

         to value, the identity of the appraisers, or any reference to the
         Appraisal Institute, or the MAI or CRE designation) shall be
         disseminated to the public through advertising media, public relations
         media, news media, sales media, or any other public means of
         communication, without the prior written consent and approval of the
         author.
<PAGE>
 
SPECIFIC ASSUMPTIONS AND LIMITING CONDITIONS
    
    1. The physical description and current condition of each subject property
       was based upon a combination of previous appraisals, inspections by
       representatives of Charles R. Wilson & Associates, Inc., and information
       provided by PS Partners II, Ltd. and PSI. Charles R. Wilson & Associates,
       Inc., assumes no responsibility for the soundness of structural members
       nor for the condition of mechanical equipment, plumbing, or electrical
       components.

    2. Pursuant to the engagement agreement, the content of the appraisal report
       has been limited as presented herein.  This report is not intended to
       meet the requirements of Title XI of the Federal Financial Institutions
       Reform, Recovery, and Enforcement Act of 1989.  Therefore, federally
       regulated institutions should not rely on this report for financing
       purposes.

    3. The portfolio valuation reported herein does not reflect any premium or
       discount a potential buyer may assign to the portfolio of properties as
       result of its size.  Neither a premium nor a discount is appropriate
       based on our experience with buyers and sellers of self-storage
       facilities.

    4. This valuation analysis assumes that capitalization and discount rates
       used in the market for valuing individual properties are appropriate to
       apply to a portfolio's cash flow for the purpose of estimating the
       portfolio's fair market value.

    5. This valuation covers only the real properties described herein and only
       applies to the valuation problems as stated and does not include
       consideration of mineral rights or related right of entry, nor personal
       property or the removal thereof.  Values reported herein are not intended
       to be valid in any other context, nor are any conclusions as to unit
       values applicable or any other property or utilization than that
       specifically identified herein.  No value has been assigned to any
       personal property, fixtures, or intangible items that are not real
       property, except for that equipment and personal property considered
       usual and incidental to the operation of the facilities such as golf
       carts, office supplies, computer systems, etc.

    6. This report invokes the Departure Provision as follows:

       Standard Rule 1-2 (c), states that the appraiser must, "consider
       easements, restrictions, encumbrances, reservations, covenants,
       contracts, declarations, special assessments, ordinances, or other items
       of a similar nature".  The effect of any easements, encumbrances, and
       similar items were not taken into consideration in this valuation
       analysis.  We were not provided copies of title reports, deed
       restrictions, or similar items nor are we aware of any restrictions or
       similar items existing that could have an impact on our valuation of the
       portfolio. At the request of the clients, this valuation analysis does
       not consider any such restrictions.

       Standard Rule 1-3 (a), states that the appraiser must "consider the
       effect on use and value of the following factors: existing land use
       regulations, reasonably probable modification of such land use
       regulation, economic demand, the physical adaptability of the property,
       neighborhood trends, and the highest and best use of the property".  City
       and county officials were not interviewed and thus it is assumed that
       each property complies with city and county building codes and zoning
       ordinances.  It is further assumed that there are no new or planned
       facilities that would negatively impact any of the portfolio's
       properties.

       Standard Rule 1-4 (b) states the appraiser must  "collect, verify,
       analyze, and reconcile:...(iv) such comparable rental data, adequately
       identified and described, as are available to estimate the market rental
       of the property being appraised;..."   Each on-site manager provided the
       appraiser with competition surveys.  The rental rates were verified and
       used to determine market rent, however, no physical inspections were made
       of competing facilities.
<PAGE>
 
    7. For properties located in California, real estate taxes used in the
       Income Approach are adjusted to reflect a fair sale, as is standard
       practice in California in compliance with Proposition 13.

    8. Capital expenditure items for deferred maintenance have not been taken
       into consideration, which if present may lower the overall value of the
       portfolio.

701 Western Avenue, Suite 200
Glendale, CA  91201-2397

Gentlemen:


     We have been advised that PS Partners, II, LTD. (the "Partnership"), a
California limited partnership, is entering into a transaction (the
"Transaction") in which the Partnership will be merged with a subsidiary of
Public Storage, Inc. ("PSI"), an affiliated, publicly traded real estate
investment trust.  In the Transaction, the limited partners of the Partnership
(the "Limited Partners") will be offered the option of converting their
interests in the Partnership (the "Units") into $697 of cash per Unit or shares
of PSI Common Stock with an equivalent market value based upon the average
closing prices on the New York Stock Exchange during the twenty consecutive
trading days ending five days prior to the closing date of the Transaction
(collectively, the "Consideration"). We have been further advised that the Unit
price offered to the Limited Partners is equivalent to the net asset value per
Unit based in part on an independent appraisal of the Partnership's properties.
We also have been advised that additional distributions will be made to the
Limited Partners prior to the consummation of the Transaction to the extent
required to cause the Partnership's net asset value as of the closing date of
the Transaction to be substantially equivalent to the estimate of the
Partnership's net asset value as of September 30, 1998 contained in the
Information Statement to be filed with the Securities and Exchange Commission.

     The Partnership has requested that Robert A. Stanger & Co., Inc.
("Stanger") provide its opinion as to the fairness to the Limited Partners
(excluding PSI or its affiliates), from a financial point of view, of the
Consideration to be received in the Transaction.

     In the course of our review to render this opinion, we have, among other
things:

     .    Reviewed the Information Statement related to the Transaction to be
          filed with the Securities and Exchange Commission (the "SEC");

     .    Reviewed the Partnership's and PSI's annual reports to shareholders
          filed with the SEC on Form 10-K for the years ending December 31,
          1995, 1996 and 1997, and the Form 10-Q filed as of March 31, 1998,
          June 30, 1998 and September 30, 1998 which reports the Partnership's
          management and PSI's management have indicated to be the most current
          financial statements available;

     .    Reviewed the MAI-certified portfolio appraisal of the properties owned
          by the Partnership as of November 30, 1998 performed by Charles R.
          Wilson & Associates Inc. (the "Appraisal"), and discussed with
          management of the Partnership and the appraiser the methodologies and
          procedures employed in preparing the Appraisal;

     .    Reviewed information regarding purchases and sales of self-storage
          properties by PSI or any affiliated entities and other information
          available relating to acquisition criteria for self-storage
          properties;

     .    Reviewed internal financial analyses and forecasts prepared by the
          Partnership, and based in part on the Appraisal, of the current net
          liquidation value per Unit of the Partnership's assets and projections
          of cash flow from operations, cash flow distributions and going-
          concern values per Unit for the Partnership, including the
          Partnership's calculation of the allocation of such values between the
          limited and general partners;

                                       1
<PAGE>
 
     .    Discussed with members of senior management of the Partnership and PSI
          conditions in self-storage property markets, conditions in the market
          for sales/acquisitions of properties similar to those owned by the
          Partnership, current and projected operations and performance,
          financial condition and future prospects of the Partnership and PSI;

     .    Reviewed historical market prices, trading volume and dividends for
          PSI Common Stock, and secondary market transactions involving
          interests in the Partnership; and

     .    Conducted other studies, analyses, inquiries and investigations as we
          deemed appropriate.

     In rendering this fairness opinion, we have relied upon and assumed,
without independent verification, the accuracy and completeness of all financial
and other information contained in the Information Statement or that was
furnished or otherwise communicated to us by the Partnership and PSI.  We have
not performed an independent appraisal of the assets and liabilities of the
Partnership or PSI and have relied upon and assumed the accuracy of the
appraisals performed by Charles R. Wilson & Associates Inc.  We have also relied
on the assurance of the Partnership and PSI that any pro forma financial
statements, projections, budgets, estimates of environmental liability, or value
estimates contained in the Information Statement or otherwise provided to us,
were reasonably prepared on bases consistent with actual historical experience
and reflect the best currently available estimates and good faith judgments;
that the allocation of Consideration to the Limited Partners has been determined
by the Partnership in accordance with the provisions of the Partnership
Agreement; that no material changes have occurred in the appraised value of the
properties or the information reviewed between the date of the Appraisal or the
date of the other information provided and the date of this letter; and that the
Partnership and PSI are not aware of any information or facts that would cause
the information supplied to us to be incomplete or misleading in any material
respect.

     We have not been requested to, and therefore did not:  (i) select the
method of determining the Consideration offered in the Transaction; (ii) make
any recommendation to the Limited Partners of the Partnership as to whether to
select the cash or Common Stock option in the Transaction; or (iii) express any
opinion as to the business decision to effect the Transaction, alternatives to
the Transaction, or tax factors resulting from the Transaction or relating to
PSI's continued qualification as a REIT.  Our opinion is based on business,
economic, real estate and securities markets, and other conditions as of the
date of our analysis and addresses the Transaction in the context of information
available as of the date of our analysis. Events occurring after that date may
materially affect the assumptions used in preparing the opinion.

     Based upon and subject to the foregoing, and in reliance thereon, it is our
opinion that as of the date of this letter the Consideration to be received in
the Transaction is fair to the public Limited Partners of the Partnership from a
financial point of view.

     The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to partial analysis or summary description. We have
advised the Partnership that our entire analysis must be considered as a whole
and that selecting portions of our analysis and the factors considered by us,
without considering all analyses and  facts, could create an incomplete view of
the evaluation process underlying this opinion.


Yours truly,


/s/ Robert A, Stanger & Co., Inc.

                    NOTES TO CONDENSED FINANCIAL STATEMENTS
                              SEPTEMBER 30, 1998
                                  (UNAUDITED)
 
1.   The accompanying unaudited condensed financial statements have been
     prepared pursuant to the rules and regulations of the Securities and
     Exchange Commission. Certain information and footnote disclosures normally
     included in financial statements prepared in accordance with generally
     accepted accounting principles have been condensed or omitted pursuant to
     such rules and regulations, although management believes that the
     disclosures contained herein are adequate to make the information presented
     not misleading. These unaudited condensed financial statements should be
     read in conjunction with the financial statements and related notes
     appearing in the Partnership's Form 10-K/A for the year ended December 31,
     1997.

2.   In the opinion of management, the accompanying unaudited condensed
     financial statements reflect all adjustments, consisting of only normal
     accruals, necessary to present fairly the Partnership's financial position
     at September 30, 1998, the results of operations for the three and nine
     months ended September 30, 1998 and 1997 and cash flows for the nine months
     then ended.

3.   The results of operations for the three and nine months ended September 30,
     1998 are not necessarily indicative of the results to be expected for the
     full year.

4.   In January 1997, the Partnership, the Joint Venture, PSI, and other related
     partnerships transferred a total of 35 business parks to PS Business Parks,
     LP ("PSBPLP"), an operating partnership formed to own and operate business
     parks in which PSI has a significant interest. Included among the
     properties transferred were the Partnership's and Joint Venture's business
     parks in exchange for respective partnership interest in PSBPLP. The
     general partners of PSBPLP is PS Business Parks, Inc.

5.   Previously, the Partnership consolidated the Joint Venture in its financial
     statements. The accompanying financial statements have been restated to de-
     consolidate the Joint Venture. This restatement had no impact upon net
     income or Partner's Equity.

6.   Summarized combined financial data with respect to the Real Estate Entities
     is as follows:

                         Report of Independent Auditors

The Partners
PS Partners II, Ltd.

We have audited the  balance sheets of PS Partners II, Ltd. as of December 31,
1997 and 1996 and the related  statements of income, partners' equity and cash
flows for each of the three years in the period ended December 31, 1997.  These
financial statements are the responsibility of the Partnership'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 PS Partners II, Ltd. 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.

As discussed in Note 1, the financial statements have been restated to account
for certain joint ventures previously consolidated by the Partnership on the
equity method.

                               December 31, 1997


1.   Summary of Significant Accounting Policies and Partnership Matters
     ------------------------------------------------------------------

     Description of Partnership
     --------------------------

          PS Partners II, Ltd. (the "Partnership") was formed with the proceeds
     of an interstate public offering.  PSI Associates II, Inc.("PSA"), an
     affiliate of Public Storage Management, Inc., organized the Partnership
     along with B. Wayne Hughes ("Hughes").  In September 1993, Storage
     Equities, Inc., now known as Public Storage, Inc. ("PSI ") acquired the
     interest of PSA relating to its general partner capital contribution in the
     Partnership and was substituted as a co-general partner in place of PSA.

          In 1995, there was a series of mergers among Public Storage
     Management, Inc. (which was the Partnership'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.  In the PSMI Merger, Storage Equities, Inc. was
     renamed Public Storage, Inc. and it acquired substantially all of PSMI's
     United States real estate operations and became the operator of the mini-
     warehouse properties that the Partnership has an interest in.

          The Partnership has invested in existing mini-warehouse storage
     facilities which offer self-service storage spaces for lease, usually on a
     month-to-month basis, to the general public and, to a lesser extent, in
     existing business park facilities which offer industrial and office space
     for lease.

          The Partnership has ownership interests in 33 properties in 12 states,
     which excludes two properties transferred to PS Business Parks, L.P.
     ("PSBPLP") in January 1997.  27 of the properties are owned by SEI/PSP II
     Joint Ventures (the "Joint Venture"), a general partnership between the
     Partnership and PSI. The Partnership is the managing general partner of the
     Joint Venture, with ownership interests in the individual properties of the
     Joint Venture ranging from 36% to 90%.

          As used hereinafter, the Joint Venture and PSBPLP are referred to as
     the "Real Estate Entities."

     Basis of Presentation
     ---------------------

          The  financial statements include the accounts of the Partnership. The
     accounts of the Joint Venture, which the Partnership does not control, are
     not consolidated with the Partnership and the Partnership's interest in the
     Joint Venture is accounted for on the equity method.

          The Partnership does not control the Joint Venture because PSI has
     significant control rights with respect to the management of the
     properties, including the right to compel the sale of each property in the
     Joint Venture and the right to require the Partnership to submit operating
     budgets.

          Previously, the Partnership consolidated the Joint Venture in its
     financial statements.  The accompanying financial statements for 1997,
     1996, and 1995 have been restated to de-consolidate the Joint Venture. This
     restatement had no impact upon net income or Partner's Equity.  The primary
     impact of this change was to reduce total assets by $15,482,000 and
     $15,708,000 in 1997 and 1996, respectively; the total of minority interest
     and liabilities was reduced by the corresponding same amount in each
     period.  Total revenues decreased by $8,039,000, $8,353,000, and
     $8,045,000, respectively, in the years ended December 31, 1997, 1996, and
     1995, respectively; the total of minority interest in income and expenses
     were reduced by the corresponding same amount in each period.

1.   Summary of Significant Accounting Policies and Partnership Matters
     ------------------------------------------------------------------
     (Continued)
     -----------

          Under the terms of the general partnership agreement of the Joint
     Venture all depreciation and amortization with respect to each property is
     allocated solely to the Partnership until the limited partners recover
     their initial capital contribution.  Thereafter,  all depreciation  and
     amortization is allocated solely to PSI until it recovers its initial
     capital contribution.  All remaining depreciation and amortization is
     allocated to the Partnership and PSI in proportion to their ownership
     percentages.

     Under the terms of the general partnership agreement of the Joint Venture,
     for property acquisitions in which PSI issued convertible securities to the
     sellers for its interest, PSI 's rights to receive cash flow distributions
     from the partnerships for any year after the first year of operation are
     subordinated to cash distributions to the Partnership equal to a cumulative
     annual 7% of its cash investment (not compounded).  These agreements also
     specify that upon sale or refinancing of a property for more than its
     original purchase price, distribution of proceeds to PSI is subordinated to
     the return to the Partnership of the amount of its cash investment and the
     7% distribution described above.

     Depreciation and amortization
     -----------------------------

          The Partnership and the Joint Venture depreciate the buildings and
     equipment on a straight-line method over estimated useful lives of 25 and 5
     years, respectively. Leasing commissions relating to business park
     properties are expensed when incurred.

     Revenue Recognition
     -------------------

          Property rents are recognized as earned.

     Allocation of Net Income
     ------------------------

          The General Partners' share of net income consists of an amount
     attributable to their 1% capital contribution and an additional percentage
     of cash flow (as defined, see Note 4) which relates to the General
     Partners' share of cash distributions as set forth in the Partnership
     Agreement.  All remaining net income is allocated to the limited partners.

     Per Unit Data
     -------------

          Per unit data is based on the number of limited partnership units
     (128,000) outstanding during the year.

     Cash Distributions
     ------------------

          The Partnership Agreement provides for quarterly distributions of cash
     flow from operations (as defined).  Cash distributions per unit were $38.34
     for 1997, $33.44 for 1996 and $61.97 for 1995.

     Cash and Cash Equivalents
     -------------------------

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

1.   Summary of Significant Accounting Policies and Partnership Matters
     ------------------------------------------------------------------
     (Continued)
     -----------

     Environmental Cost
     ------------------

          Substantially all of the real estate facilities in which the
     Partnership has an interest were acquired prior to the time that it was
     customary to conduct extensive environmental investigations in connection
     with the property acquisitions.  During the fourth quarter of 1995, an
     independent environmental consulting firm completed environmental
     assessments on the properties of the Partnership and the Joint Venture to
     evaluate the environmental condition of, and potential environmental
     liabilities of such properties.  Based on the assessments, the Partnership
     believes that after December 31, 1997 it is probable that the Mini-
     Warehouse Properties will incur costs totaling $68,000.  During 1997, 1996,
     and 1995, the Partnership and the Joint Venture paid none, $12,000, and
     $44,000, respectively, in connection with environmental remediations.
     Although there can be no assurance, the Partnership is not aware of any
     unaccrued environmental contamination of the Mini-Warehouse Properties
     which individually or in the aggregate would be material to the
     Partnership's overall business, financial condition, or results of
     operations.

     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.

2.   Real Estate Facilities
     ----------------------

          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 method of accounting for long-lived assets that are expected
     to be disposed.  The Partnership adopted Statement 121 in 1996 and the
     adoption had no effect.

          In January 1997, the Partnership and PSI and other related
     partnerships transferred a total of 35 business parks to PSBPLP, an
     operating partnership formed to own and operate business parks in which PSI
     has a significant interest.  Included among the properties transferred was
     the Partnership's business park in exchange for a partnership interest in
     PSBPLP.  The general partner of PSBPLP is PS Business Parks, Inc. ("PSB").

3.   Investment in real estate entities
     ----------------------------------

         During 1997, 1996, and 1995, the Partnership recognized earnings from
     the Real Estate Entities of $3,454,000, $2,652,000, and $2,735,000,
     respectively, and received cash distributions totaling $3,961,000,
     $3,101,000, and $4,465,000, respectively from the Real Estate Entities.

                               December 31, 1997

3.   Investment in real estate entities (Continued)
     ----------------------------------------------

          In November 1994, the Massachusetts Bay Transportation Authority
     exercised its right of eminent domain and took possession of the mini-
     warehouse located in Weymouth, Massachusetts which was owned jointly by the
     Partnership and PSI.  This Joint Venture received initial condemnation
     proceeds of approximately $1,910,000, resulting in the recognition of a
     gain on disposition of real estate facilities of $224,000.

          The Partnership is presently contesting the amount of the initial
     condemnation proceeds, however, there is no assurance that the Partnership
     will obtain additional condemnation proceeds.

          The accounting policies of the Real Estate Entities are similar to
     that of the Partnership.  Summarized combined financial data with respect
     to the Real Estate Entities are as follows:

<TABLE>

 Total liabilities                                               12,347,000                     639,000

</TABLE>

         The increase in the size of the combined financial position and
     operating results, respectively, of the Real Estate Entities for the year
     ended December 31, 1997 and at December 31, 1997, respectively, as compared
     to prior periods, is the result of the January 1997 transfer of business
     parks owned by the Joint Venture and the Partnership to PSBPLP, which was
     formed to own and operate business parks.

         Financial statements of the Joint Venture are filed with the
     Partnership's Form 10-K for 1997, in Item 14.  PS Business Parks, Inc. is a
     registrant with the Securities and Exchange Commission, and its filings can
     be accessed through the Securities and Exchange Commission.

4.   General Partners' Equity
     ------------------------

          The General Partners have a 1% interest in the Partnership.  In
     addition, the General Partners have a 10% interest in cash distributions
     attributable to operations, exclusive of distributions attributable to
     sales and refinancing proceeds.

          Proceeds from sales and refinancings will be distributed entirely to
     the limited partners until the limited partners recover their investment
     plus a cumulative 8% annual return (not compounded); thereafter, the
     General Partners have a 15% interest in remaining proceeds.

                               December 31, 1997


5.   Related Party Transactions
     --------------------------

          The Partnership has a management agreement with PSI whereby PSI
     operates the Mini-Warehouse Properties for a fee equal to 6% of the
     facilities' monthly gross revenue (as defined).

          In January 1997, the Partnership and the Joint Venture transferred
     their business park facilities to PSBPLP in exchange for a partnership
     interest in PSBPLP.

          PSI has a significant economic interest in PSBPLP and PSBP.

6.   Leases
     ------

          The Partnership has invested primarily in existing mini-warehouse
     storage facilities which offer self-service storage spaces for lease to the
     general public.  Leases for such space are usually on a month-to-month
     basis.

7.   Taxes Based on Income
     ---------------------

          Taxes based on income are the responsibility of the individual
     partners and, accordingly, the Partnership's  financial statements do not
     reflect a provision for such taxes.

          Unaudited taxable net income was $6,509,000, $2,637,000 and $4,068,000
     for the years ended December 31, 1997, 1996 and 1995, respectively.  The
     difference between taxable income and book income is primarily related to
     timing differences in depreciation expense.

                         Report of Independent Auditors

The Partners
SEI/PSP II Joint Ventures

We have audited the  balance sheets of the SEI/PSP II Joint Ventures as of
December 31, 1997 and 1996 and the related statements of income, partners'
equity and cash flows for each of the three years in the period ended December
31, 1997.  These financial statements are the responsibility of the Joint
Ventures' management.  Our responsibility is to express an opinion on these
financial statements 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 the SEI/PSP II Joint Ventures
at December 31, 1997 and 1996, and the results of its operations and cash flows
for each of the three years in the period ended December 31, 1997, in conformity
with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS
                               December 31, 1997

1.   Description of Partnership
     ---------------------------

          SEI/PSP II Joint Ventures (the "Joint Venture") was formed on December
     31, 1990 in connection with the consolidation of 22 separate general
     partnerships between Public Storage Inc. ("PSI") and PS Partners II, Ltd.
     ("PSP II"). The Joint Venture, through its predecessor general
     partnerships, invested in existing mini-warehouse facilities which offer
     self-service storage spaces for lease, usually on a month-to-month basis,
     to the general public and, to a lesser extent, in existing business park
     facilities which offer industrial and office space for lease.

          The Joint Venture owns 27 properties (referred to hereinafter as the
     "Mini-Warehouses"), which excludes one property which was transferred to PS
     Business Parks, L.P. ("PSBPLP") in January 1997.   PSP II is the managing
     general partner of the Joint Venture, with its ownership interests in the
     properties of the Joint Venture ranging from 36% to 90%.

2.   Summary of Significant Accounting Policies and Partnership Matters
     ------------------------------------------------------------------

     Basis of Presentation
     ---------------------

          The  financial statements include the accounts of the Joint Venture.

          Under the terms of the general partnership agreement of the Joint
     Venture, for property acquisitions in which PSI issued convertible
     securities to the sellers for its interest, PSI's right to receive cash
     flow distributions for any year after the first year of operation are
     subordinated to cash distributions to PSP II equal to a cumulative annual
     7% of its cash investment (not compounded).   In addition, upon sale or
     refinancing of a property for more than its original purchase price,
     distribution of proceeds to PSI is subordinated to the return to PSP II of
     the amount of its cash investment and the 7% distribution described above.

     Depreciation and amortization
     -----------------------------

          The Joint Venture depreciates the buildings and equipment on a
     straight-line method over estimated useful lives of 25 and 5 years,
     respectively. Leasing commissions relating to business park properties are
     expensed when incurred.

     Revenue Recognition
     -------------------

          Property rents are recognized as earned.

     Allocation of Net Income to PSP II and PSI
     ------------------------------------------

          Net income prior to depreciation is allocated to PSP II and PSI based
     upon their relative ownership interest in each property and the results of
     each property.

          Under the terms of the general partnership agreement of the Joint
     Venture all depreciation and amortization with respect to each Joint
     Venture is allocated solely to PSP II until it recovers its initial capital
     contribution.  Thereafter,  all depreciation  and amortization is allocated
     solely to PSI until it recovers its initial capital contribution.  All
     remaining depreciation and amortization is allocated to PSP II and PSI in
     proportion to their ownership percentages.

                         NOTES TO FINANCIAL STATEMENTS
                               December 31, 1997

2.   Summary of Significant Accounting Policies and Partnership Matters
     ------------------------------------------------------------------
       (Continued)
       -----------

     Cash Distributions
     ------------------

          The general partnership agreement of the Joint Venture provides for
     regular distributions of cash flow from operations (as defined).

     Cash and Cash Equivalents
     -------------------------

          For financial statement purposes, the Joint Venture considers all
     highly liquid investments purchased with a maturity of three months or less
     to be cash equivalents.

     Environmental Cost
     ------------------

          Substantially all of the real estate facilities in which the Joint
     Venture has an interest were acquired prior to the time that it was
     customary to conduct extensive environmental investigations in connection
     with the property acquisitions.  During the fourth quarter of 1995, an
     independent environmental consulting firm completed environmental
     assessments on the Joint Venture's properties to evaluate the environmental
     condition of, and potential environmental liabilities of such properties.
     Based upon these evaluations, the Joint Venture accrued a total of $76,000
     of environmental expense in 1995.  Although there can be no assurance, the
     Joint Venture is not aware of any additional unaccrued environmental
     contamination of the Mini-Warehouses.

     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.

3.   Real Estate Facilities
     ----------------------

          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 method of accounting for long-lived assets that are expected
     to be disposed.  The Joint Venture adopted Statement 121 in 1996 and the
     adoption had no effect.

          In November 1994, the Massachusetts Bay Transportation Authority
     exercised its right of eminent domain and took possession of the Joint
     Venture's mini-warehouse located in Weymouth, Massachusetts.  The Joint
     Venture received initial condemnation proceeds of approximately $1,910,000,
     resulting in the recognition of a gain on disposition of real estate
     facilities of $224,000.

                               December 31, 1997


3.   Real Estate Facilities (Continued)
     ----------------------------------

          The Joint Venture is presently contesting the amount of the initial
     condemnation proceeds, however, there is no assurance that additional
     condemnation proceeds will be received.

          In January 1997, the Joint Venture and PSI and other affiliated
     partnerships of PSI transferred a total of 35 business parks to PSBPLP, an
     operating partnership formed to own and operate business parks in which PSI
     has a significant interest.  Included among the properties transferred was
     the Joint Venture's business park in exchange for a partnership interest in
     PSBPLP.  The general partner of PSBPLP is PS Business Parks, Inc.

4.   Investment in real estate entity
     --------------------------------

          In 1997, the Joint Venture recognized $187,000 in equity in earnings
     of real estate entities with respect to the investment in PSBPLP described
     in Note 1 above.

          The accounting policies of PSBPLP are similar to that of the Joint
     Venture.  Summarized combined financial data with respect to PSBPLP is as
     follows:

         PS Business Parks, Inc., which owns PSBPLP, is a registrant with the
     Securities and Exchange Commission, and its filings can be accessed through
     the Securities and Exchange Commission.

5.   Related Party Transactions
     --------------------------

          The Joint Venture has a management agreement with PSI whereby PSI
     operates the Mini-Warehouses for a fee equal to 6% of the facilities'
     monthly gross revenue (as defined).

          In January 1997, the Joint Venture transferred its business park
     facility to PSBPLP in exchange for a partnership interest in PSBPLP.

          PSI has a significant economic interest in PSBPLP and PSBP.

6.   Leases
     ------

          The Joint Venture has invested primarily in existing mini-warehouse
     storage facilities which offer self-service storage spaces for lease to the
     general public.  Leases for such space are usually on a month-to-month
     basis.

7.   Taxes Based on Income
     ---------------------

          Taxes based on income are the responsibility of PSP II and PSI and,
     accordingly, the Joint Venture's financial statements do not reflect a
     provision for such taxes.

          Unaudited taxable net income was $4,468,000, $1,152,000, and
     $3,537,000 for the years ended December 31, 1997, 1996 and 1995,
     respectively.  The difference between taxable income and book income is
     primarily related to timing differences in depreciation expense.

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

Forward Looking Statements
- --------------------------

     Management's Discussion and Analysis of Financial Condition and Results of
Operations contains "forward looking" statements that involve risks and
uncertainties and are based upon a number of assumptions.  Actual results and
trends may differ materially depending upon a number of factors.  Information
regarding these factors is contained in the Partnership's Annual Report on Form
10-K/A for the fiscal year ended December 31, 1997 and in the reports for the
quarterly periods on Form 10-Q/A for the quarters ended March 31, 1998 and June
30, 1998.

Results of Operations - Financials at September 30, 1998
- --------------------------------------------------------

Three months ended September 30, 1998 compared to three months ended September
30, 1997:

     The Partnership's net income for the three months ended September 30, 1998
was $1,513,000 compared to $1,279,000 for the three months ended September 30,
1997, representing an increase of $234,000, or 18%.  The increase was primarily
due to the Partnership's share of improved property operations at the real
estate facilities that the Partnership has an interest in, combined with a
decrease in depreciation expense allocated to the Partnership with respect to
the Joint Venture.

Property Operations
- -------------------

     Rental income for the Partnership's wholly-owned mini-warehouse properties
was $768,000 compared to $729,000 for the three months September 30, 1998 and
1997, respectively, representing an increase of $39,000, or 5%.  Cost of
operations (including management fees) increased $28,000, or 13%, to $252,000
from $224,000 for the three months ended September 30, 1998 and 1997,
respectively.  Accordingly, for the Partnership's wholly-owned mini-warehouse
properties, property net operating income increased by $11,000, or 2%, from
$505,000 to $516,000 for the three months ended September 30, 1997 and 1998,
respectively.

Equity in Earnings of Real Estate Entities
- ------------------------------------------

     Equity in earnings of real estate entities was $1,159,000 in the three
months ended September 30, 1998 as compared to $950,000 during the three months
ended September 30, 1997, representing an increase of $209,000, or 22%.  This
was due primarily to the Partnership's share of improved operating results at
the Joint Venture's mini-warehouses, combined with a decrease in depreciation
expense allocated to the Partnership with respect to the Joint Venture.

Depreciation and Amortization
- -----------------------------

     Depreciation and amortization increased $9,000, or 6%, to $163,000 from
$154,000 for the three months ended September 30, 1997 and 1998, respectively.
This increase was primarily attributable to the depreciation of capital
expenditures made during 1997 and 1998.

                              Appendix F - Page 1
<PAGE>
 
Nine months ended September 30, 1998 compared to nine months ended September 30,
1997:

     The Partnership's net income for the nine months ended September 30, 1998
was $3,989,000 compared to $3,516,000 for the nine months ended September 30,
1997, representing an increase of $473,000, or 13%.  The increase was primarily
due to the Partnership's share of improved property operations at the real
estate facilities that the Partnership has an interest in, combined with a
decrease in depreciation expense allocated to the Partnership with respect to
the Joint Venture.

Property Operations
- -------------------

     Rental income for the Partnership's wholly-owned mini-warehouse properties
was $2,176,000 compared to $2,106,000 for the nine months September 30, 1998 and
1997, respectively, representing an increase of $70,000, or 3%.  Cost of
operations (including management fees) increased $47,000, or 7%, to $738,000
from $691,000 for the nine months ended September 30, 1998 and 1997,
respectively.  Accordingly, for the Partnership's mini-warehouse properties,
property net operating income increased by $23,000, or 2%, from $1,415,000 to
$1,438,000 for the nine months ended September 30, 1997 and 1998, respectively.

Equity in Earnings of Real Estate Entities
- ------------------------------------------

     Equity in earnings of real estate entities was $3,061,000 in the nine
months ended September 30, 1998 as compared to $2,629,000 during the nine months
ended September 30, 1997, representing an increase of $432,000, or 16%.  This
was due primarily to the Partnership's share of improved operating results at
the Joint Venture's mini-warehouses, combined with a decrease in depreciation
expense allocated to the Partnership with respect to the Joint Venture.

Depreciation and Amortization
- -----------------------------

     Depreciation and amortization increased $23,000, or 5%, from $459,000 to
$482,000 for the nine months ended September 30, 1997 and 1998, respectively.
This increase was primarily attributable to the depreciation of capital
expenditures made during 1997 and 1998.

Supplemental Property Data
- --------------------------

     Most of the Partnership's net income is from the Partnership's share of the
operating results of the Mini-Warehouse Properties.  Therefore, in order to
evaluate the Partnership's operating results, the General Partners analyze the
operating performance of  the Mini-Warehouse Properties.

Three months ended September 30, 1998 compared to three months ended September
30, 1997:

     Rental income for the Mini-Warehouse Properties was $3,708,000 compared to
$3,524,000 for the three months ended September 30, 1998 and 1997, respectively,
representing an increase of $184,000, or 5%.  The increase in rental income was
primarily attributable to increased rental rates at the Mini-Warehouse
Properties, combined with increased average occupancy levels.  The monthly
average realized rent per square foot for the Mini-Warehouse Properties was $.68
compared to $.65 for the three months ended September 30, 1998 and 1997,
respectively.  The weighted average occupancy levels at the Mini-Warehouse
Properties increased from 92% to 93% for the three months ended September 30,
1997 and 1998, respectively.  Cost of operations (including management fees)
increased $82,000, or 7%, to $1,300,000 from $1,218,000 for the three months
ended September 30, 1998 and 1997, respectively.  This increase was primarily
attributable to increases in payroll, property tax, and advertising and
promotion (due primarily to the PSI national telephone reservation center)
expenses.  Accordingly, for the Mini-Warehouse Properties, property net
operating income increased by $102,000 from $2,306,000 to $2,408,000 for the
three months ended September 30, 1997 and 1998, respectively.

                              Appendix F - Page 2
<PAGE>
 
Nine months ended September 30, 1998 compared to nine months ended September 30,
1997:

     Rental income for the Mini-Warehouse Properties was $10,576,000 compared to
$10,181,000 for the nine months ended September 30, 1998 and 1997, respectively,
representing an increase of $395,000, or 4%.  The increase in rental income was
primarily attributable to increased rental rates at the Mini-Warehouse
Properties, combined with increased average occupancy levels.  The monthly
average realized rent per square foot for the mini-warehouse facilities was $.66
compared to $.64 for the nine months ended September 30, 1998 and 1997,
respectively.  The weighted average occupancy levels at the Mini-Warehouse
Properties increased from 90% to 91% for the nine months ended September 30,
1997 and 1998, respectively.  Cost of operations (including management fees)
increased $212,000, or 6%, to $3,920,000 from $3,708,000 for the nine months
ended September 30, 1998 and 1997, respectively.  This increase was primarily
attributable to increases in advertising and promotion (due primarily to the PSI
national telephone reservation center), property tax, repairs and maintenance,
and payroll expenses.  Accordingly, for the Mini-Warehouse Properties, property
net operating income increased by $183,000, or 3%, from $6,473,000 to $6,656,000
for the nine months ended September 30, 1997 and 1998, respectively.

Results of Operations - Financials at December 31, 1997
- -------------------------------------------------------

Year ended December 31, 1997 compared to year ended December 31, 1996:

     The Partnership's net income was $4,634,000 in 1997 compared to $4,114,000
in 1996, representing an increase of $520,000, or 12.6%. The increase is due
primarily to the Partnership's share of an improvement in operations of the
mini-warehouses in which the Partnership has an interest (the "Mini-Warehouse
Properties").

Property Operations
- -------------------

     Rental income for the Partnership's wholly-owned mini-warehouse properties
was $2,818,000 in 1997 compared to $2,715,000 during 1996, representing an
increase of $103,000, or 3.8%.   Cost of operations (including management fees)
increased $37,000, or  4.1%, to $937,000 during 1997 from $900,000 in 1996,
respectively.   Accordingly, for the Partnership's wholly-owned mini-warehouse
properties, net operating income increased by $66,000, or 3.6%, from $1,815,000
in 1996 to $1,881,000 during 1997.

     As a result of contribution of the Partnership's business park to PSBPLP in
January 1997 in exchange for operating partnership units,  rental income and
cost of operations, respectively, for the Partnership's business park was
reduced to zero and zero, respectively, in 1997 from $1,676,000 and $857,000,
respectively, in 1996.

Equity in earnings of real estate entities
- ------------------------------------------

     Equity in earnings of real estate entities was $3,454,000 in 1997 as
compared to $2,652,000 during 1996, representing an increase of $802,000, or
30.2%.  The increase was due primarily to the impact of the contribution of the
business parks of the Partnership and the Joint Venture to PSBPLP in January
1997.

Depreciation and Amortization
- -----------------------------

     Depreciation and amortization for the Partnership's wholly-owned properties
decreased $464,000 from $1,080,000 in 1996 to $616,000 in 1997.  This decrease
was primarily attributable to the impact of the contribution of the
Partnership's wholly-owned business park facility to PSBPLP, offset partially by
additional depreciation on capital expenditures made during 1996 and 1997.

Year ended December 31, 1996 compared to year ended December 31, 1995:

     The Partnership's net income in 1996 was $4,114,000 compared to $4,185,000
in 1995, representing a decrease of $71,000, or 1.7%.  The decrease was
primarily due to an increase in depreciation expense and a

                              Appendix F - Page 3
<PAGE>
 
decrease in interest income, partially offset by the Partnership's share of
improved property operations at the Mini Warehouse Properties combined with a
reduction in environmental costs.

Property Operations
- -------------------

     Rental income for the Partnership's wholly-owned mini-warehouse properties
was $2,715,000 in 1996 compared to $2,592,000 during 1995, representing an
increase of $123,000, or 4.7%.   Cost of operations (including management fees)
increased $23,000, or 2.6%, to $900,000 during 1996 from $877,000 in 1995,
respectively.  Accordingly, for the Partnership's wholly-owned mini-warehouse
properties, property net operating income increased by $100,000, or 5.8%, from
$1,715,000 in 1995 to $1,815,000 during 1996.

     Rental income for the Partnership's wholly-owned business park was
$1,676,000 in 1996 compared to $1,556,000 in 1995, representing an increase of
$120,000 or 7.7%.   Cost of operations (including management fees) increased
$56,000, or 7.0%, from $801,000 in 1995 to $857,000 in 1996.  Accordingly, for
the Partnership's wholly-owned business park property, net operating income
increased by $63,000, or 8.3%, from $755,000 in 1995 to $818,000 in 1996.

Equity in earnings of real estate entities
- ------------------------------------------

     Equity in earnings of real estate entities was $2,652,000 in 1996 as
compared to $2,735,000 during 1995, representing a decrease of $83,000, or 3.0%.
This decrease was due primarily to a reduction in operating income in the Joint
Venture's business park, partially offset by the Partnership's share of improved
operating results at the Joint Venture's mini-warehouse properties.

Depreciation and Amortization
- -----------------------------

     Depreciation and amortization attributable to the Partnership's wholly-
owned properties increased $107,000 from $973,000 in 1995 to $1,080,000 in 1996.
This increase was primarily attributable to the depreciation of capital
expenditures made during 1995 and 1996.

Supplemental Property Data
- --------------------------

     Most of the Partnership's net income is from the Partnership's share of the
operating results of the Mini-Warehouse Properties.  Therefore, in order to
evaluate the Partnership's operating results, the General Partners analyze the
operating performance of  the Mini-Warehouse Properties.

Year ended December 31, 1997 compared to the year ended December 31, 1996:

     Rental income for the Mini-Warehouse Properties was $13,617,000 in 1997
compared to $13,049,000 during 1996, representing an increase of $568,000, or
4.4%.  The increase in rental income was primarily attributable to increased
rental rates, partially offset by decreased average occupancy levels.  The
monthly average realized rent per square foot was $.64 in 1997 compared to $.61
in 1996.  The weighted average occupancy levels decreased from 91% in 1996 to
90% in 1997.  Cost of operations (including management fees) increased $222,000,
or 4.7%, to $4,973,000 during 1997 from $4,751,000 in 1996, respectively.  This
increase was primarily attributable to increases in advertising, property tax,
and management expenses.  Accordingly, for the Mini-Warehouse Properties,
property net operating income increased by $346,000, or 4.2%, from $8,298,000 in
1996 to $8,644,000 during 1997.

Year ended December 31, 1996 compared to the year ended December 31, 1995:

     Rental income for the Mini-Warehouse Properties  was $13,049,000 in 1996
compared to $12,564,000 in 1995, representing an increase of $485,000, or 3.9%.
The increase in rental income was primarily attributable to

                              Appendix F - Page 4
<PAGE>
 
increased average realized rental rates combined with increased average
occupancy levels. The monthly average realized rent per square foot was $.61 in
1996 compared to $.59 in 1995. The weighted average occupancy levels were 91% in
1996 compared to 90% in 1995. Costs of operations (including management fees)
increased $232,000, or 5.1%, to $4,751,000 in 1996 from $4,519,000 in 1995. This
increase was primarily attributable to increases in advertising and promotion,
repairs and maintenance, and office expenses. Accordingly, for the Mini-
Warehouse Properties, property net operating income increased by $253,000, or
3.1%, to $8,298,000 in 1996 from $8,045,000 in 1995.

Liquidity and Capital Resources
- -------------------------------

     The Partnership has adequate sources of cash to finance its operations,
both on a short-term and long-term basis, primarily by internally generated cash
from property operations and distributions from Real Estate Entities, combined
with cash on hand at September 30, 1998 of $2,651,000.

     The Partnership has adequate sources of cash to finance its operations,
both on a short-term and long-term basis, primarily from internally generated
cash from property operations and cash reserves.  Cash generated from operations
and distributions from real estate entities ($5,583,000 for the year ended
December 31, 1997 and $5,558,000 for the nine months ended September 30, 1998)
has been sufficient to meet all current obligations of the Partnership.  Total
capital improvements for the Partnership's wholly-owned properties were
$260,000, $367,000 and $335,000 in 1997, 1996, and 1995, respectively.  During
1998, the Partnership anticipates approximately $226,000 of capital improvements
to the Partnership's wholly-owned properties; total capital improvements for the
nine months ended September 30, 1998 with respect to these properties were
$191,000.  During 1995, the Partnership's property manager commenced a program
to enhance the visual appearance of the mini-warehouse facilities.  Such
enhancements include new signs, exterior color schemes, and improvements to the
rental offices.

     Total distributions paid to the General Partners and the limited partners
(including the per Unit amounts) for 1997 and prior years and for the nine
months ended September 30, 1998 were as follows:

     During 1990 and 1992, distribution levels were reduced to enable the Joint
Venture to retain operating cash flows which were used to retire mortgage notes
which were scheduled to mature in 1992, 1993 and 1994 (such mortgage notes
having balloon payments at maturity).  The 1992 distribution includes a special
distribution of cash reserves of approximately $3.60 per Unit  The 1995
distribution includes a special distribution of cash reserves and proceeds from
the Weymouth property condemnation of approximately $31.32 per Unit.  The 1997
distribution includes a special distribution of cash reserves of approximately
$4.90 per Unit.  Future distribution levels will be

based upon cash flows available for distributions (cash flows from operations
and distributions from real estate entities, less capital improvements and
necessary cash reserves).

Impact of Year 2000
- -------------------

     PSI has completed an assessment of all of its hardware and software
applications to identify susceptibility to what is commonly referred to as the
"Y2K Issue" whereby certain computer programs have been written using two digits
rather than four to define the applicable year.  Any of PSI's computer programs
or hardware with the Y2K Issue that have date-sensitive applications or embedded
chips may recognize a date using "00" as the year 1900 rather than the year
2000, resulting in miscalculations or system failure causing disruptions of
operations.

     Many of PSI's critical applications, relative to the direct management of
properties, have recently been replaced and PSI believes they are already Year
2000 compliant.  PSI has an implementation in process on the remaining critical
applications, including its general ledger and related systems, that are
believed to have Y2K issues.  PSI expects the implementation to be complete by
June 1999.  Contingency plans have been developed for use in case PSI's
implementations are not completed on a timely basis.  While PSI presently
believes that the impact of the Y2K Issue on its systems can be mitigated, if
the plan for ensuring Year 2000 Compliance and the related contingency  plans
were to fail, be insufficient, or not be implemented on a timely basis,
operations of the Partnership could be materially impacted.

     Certain of PSI's other non-computer related systems that may be impacted by
the Y2K Issue, such as security systems, are currently being evaluated, and PSI
expects the evaluation to be complete by June 1999.  PSI expects the
implementation of any required solutions to be complete in advance of December
31, 1999.  PSI has not fully evaluated the impact of lack of Year 2000
compliance on these systems, but has no reason to believe that lack of
compliance would materially impact the operations of the Partnership.

     The Partnership exchanges electronic data with certain outside vendors in
the banking and payroll processing areas.  PSI has been advised by these vendors
that their systems are or will be Year 2000 compliant, but has requested a Year
2000 compliance certification from these entities.  PSI is not aware of any
other vendors, suppliers, or other external agents with a Y2K Issue that would
materially impact the Partnership's results of operations, liquidity, or capital
resources.  However, PSI has no means of ensuring that external agents will be
Year 2000 compliant, and there can be no assurance that the Partnership has
identified all such external agents.   The inability of external agents to
complete their Year 2000 compliance process in a timely fashion could materially
impact the Partnership.  The effect of non-compliance by external agents is not
determinable.

     The total cost of PSI's year 2000 compliance activities (which primarily
consists of the costs of new systems) will be allocated to all entities that use
the PSI computer systems.  The amount to be allocated to the Partnership and the
Joint Venture  is estimated at approximately $132,000.  These costs are
capitalized.

     The costs of the projects and the date on which PSI believes that it will
be Year 2000 compliant are based upon management's best estimates, and were
derived utilizing numerous assumptions of future events.  There can be no
assurance that these estimates will be achieved, and actual results could differ
materially from those anticipated.  There can be no assurance that PSI has
identified all potential Y2K Issues either within PSI and the Partnership or at
external agents.  In addition, the impact of the Y2K issue on governmental
entities and utility providers and the resultant impact on the Partnership, as
well as disruptions in the general economy, may be material but cannot be
reasonably determined or quantified.

                     INFORMATION NOT REQUIRED IN PROSPECTUS


ITEM 20.  Indemnification of Directors, Officers and Agents.

    In August 1988, the Company's Articles of Incorporation were amended (as
approved by the shareholders in August 1988) to provide that the Company may
indemnify the agents of the Company to the maximum extent permitted under
California law.  See Section V of the Certificate of Amendment of Articles of
Incorporation (Exhibit 3.11) and Article VII of the By-Laws (Exhibit 3.23) which
are incorporated herein by this reference.  In October 1988, the Company also
entered into indemnity agreements (in the form approved by the shareholders in
August 1988) with its management and non-management directors and executive
officers.  The agreements permit the Company to indemnify directors and
executive officers to the maximum extent permitted under California law and
prohibit the Company from terminating its indemnification obligations as to acts
or omissions of any director or executive officer occurring before the
termination.  The indemnification and limitations on liability permitted by the
amendment to the Articles of Incorporation and the agreements are subject to the
limitations set forth by California law.  The Company believes the
indemnification agreements will assist it in attracting and retaining qualified
individuals to serve as directors and executive officers of the Company.


ITEM 21.  Exhibits and Financial Statement Schedules.

     (a)  Exhibits:  See Exhibit Index contained herein.

     (b)  Financial Statement Schedules:

          See Index to Financial Statement Schedules in registrant's Annual
Report on Form 10-K for the year ended December 31, 1997 and incorporated herein
by reference.

          All other financial statement schedules are omitted since the required
information is not present or not present in amounts sufficient to require
submission of the schedule, or because the information required is  included in
the consolidated financial statements or the notes thereto.


ITEM 22.  Undertakings.

    The undersigned Registrant hereby undertakes as follows:

    1.    To file, during any period in which offers or sales are being made, a
post-effective amendment to this registration statement:

         (i)  To include any prospectus required by Section 10(a)(3) of the
         Securities Act of 1933;

         (ii) To reflect in the prospectus any facts or events arising after the
         effective date of the registration statement (or the most recent post-
         effective amendment thereof) which, individually or in the aggregate,
         represent a fundamental change in the information set forth in the
         registration statement.  Notwithstanding the foregoing, any increase or
         decrease in volume of securities offered (if the total dollar value of
         securities offered would not exceed that which was registered) and any
         deviation from the low or high and of the estimated maximum offering
         range may be reflected in the form of prospectus filed with the
         Commission pursuant to Rule 424(b) if, in the aggregate, the changes in
         volume and price represent no more than 20 percent change in the
         maximum aggregate offering price set forth in the "Calculation of
         Registration Fee" table in the effective registration statement.

                                      S-1
<PAGE>
 
       (iii)  To include any material information with respect to the plan of
       distribution not previously disclosed in the registration statement or
       any material change to such information in the registration statement.

Provided, however, that paragraphs 1.(i) and 1.(ii) do not apply if the
registration statement is on Form S-3 or Form S-8, and the information required
to be included in a post-effective amendment by those paragraphs is contained in
periodic reports filed by the registrant pursuant to Section 13 or Section 15(d)
of the Securities Exchange Act of 1934 that are incorporated by reference in the
registration statement.

   2.  That, for the purpose of determining any liability under the Securities
Act of 1933, each such post-effective amendment shall be deemed to be a new
registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

   3.  To remove from registration by means of a post-effective amendment any of
the securities being registered which remain unsold at the termination of the
offering.

   4.  That, for purposes of determining any liability under the Securities Act
of 1933, each filing of the registrant's annual report pursuant to section 13(a)
or section 15(d) of the Securities Exchange Act of 1934 (and, where applicable,
each filing of an employee benefit plan's annual report pursuant to section
15(d) of the Securities Exchange Act of 1934) that is incorporated by reference
in the registration statement shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

   5.  That prior to any public reoffering of the securities registered
hereunder through use of a prospectus which is a part of this registration
statement, by any person or party who is deemed to be an underwriter within the
meaning of Rule 145(c), the issuer undertakes that such reoffering prospectus
will contain the information called for by the applicable registration form with
respect to reofferings by persons who may be deemed underwriters, in addition to
the information called for by the other Items of the applicable form.

   6.  That every prospectus (i) that is filed pursuant to paragraph (5)
immediately preceding, or (ii) that purports to meet the requirements of section
10(a)(3) of the Act and is used in connection with an offering of securities
subject to Rule 415, will be filed as a part of an amendment to the registration
statement and will not be used until such amendment is effective, and that, for
purposes of determining any liability under the Securities Act of 1933, each
such post-effective amendment shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

   7.  To respond to requests for information that is incorporated by reference
into the prospectus pursuant to Item 4, 10(b), 11, or 13 of this form, within
one business day of receipt of such request, and to send the incorporated
documents by first class mail or other equally prompt means.  This includes
information contained in documents  filed subsequent to the effective date of
the registration statement through the date of responding to the request.

   8.  Except as permitted by General Instruction H to Form S-4 (in a
transaction not covered by General Instruction I), to supply by means of a post-
effective amendment all information concerning a transaction, and the company
being acquired involved therein, that was not the subject of and included in the
registration statement when it became effective.

    Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions described under Item 20 above,
or otherwise, the Registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the Securities Act of 1933 and is, therefore, unenforceable.  In
the event that a claim for indemnification against such liabilities (other than
the payment by the registrant of expenses incurred or paid by a director,
officer or controlling person of the Registrant in the successful defense of any
action, suit or proceeding) is asserted by such director, officer or controlling
person in connection with the securities being registered, the Registrant will,
unless in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act of 1933 and will be governed by the final adjudication of such
issue.

Public Storage, Inc.
701 Western Avenue
Glendale, California 91201-2397

Gentlemen:

     As Senior Vice President and General Counsel of Public Storage, Inc. (the
"Company"), I have examined the Registration Statement on Form S-4, which is
expected to be filed by the Company with the Securities and Exchange Commission
on or about the date of delivery of this opinion (the "Registration Statement"),
which relates to the offer and sale of up to 1,000,000 shares of the Company's
common stock, par value $.10 per share (the "Shares").

     I am familiar with the proceedings taken or to be taken by the Company
relating to the authorization and issuance of the Shares in the manner set forth
in the Registration Statement.  I have also examined the Company's Restated
Articles of Incorporation and Revised Bylaws and have made such other
investigation as I have deemed necessary in order to express the opinions
contained herein.

     It is my opinion that:

     1.   The Company is a corporation duly organized and validly existing in
good standing under the laws of the State of California.

     2.   The Shares, when issued and delivered in the manner and on the terms
described in the Registration Statement, will be legally issued, fully paid and
nonassessable.

     I hereby consent to the reference to me under the caption "Legal Opinions"
in the Registration Statement and to the filing of this opinion as an exhibit to
the Registration Statement or amendments thereto.

                                  Very truly yours,

                                  /S/ DAVID GOLDBERG

                      Re:  Merger Transaction Tax Opinion
                           ------------------------------

Ladies & Gentlemen:

     As Senior Vice President and Tax Counsel of Public Storage, Inc. ("PSI"), I
have examined the registration statement expected to be filed by PSI on Form S-4
with the Securities and Exchange Commission on or about the date of this opinion
(the "Registration Statement").  Unless otherwise defined in this opinion
letter, capitalized terms used below have the same meaning as set forth in the
Registration Statement.  The Registration Statement serves as the definitive
information statement relating to PSI's acquisition of the interests held by the
public limited partners of PS Partners II, Ltd. ("Partners II"), pursuant to a
proposed merger of PS Partners II Merger Co., Inc. ("Merger Sub," which is a
second tier subsidiary of PSI) with and into Partners II (the "Merger").  In the
Merger, each Partners II partnership unit (other than the partnership units held
by PSI and its subsidiaries) will be converted into the right to receive PSI
common stock with a value of $697, or at the election of a limited partner, $697
in cash.  PSI is a general partner of Partners II and now owns indirectly
approximately 74% of the outstanding limited partnership interests in Partners
II.

     In connection with your participation in the Merger, you have requested my
opinion that the discussion in the Registration Statement under the heading
"Federal Income Tax Considerations" fairly summarizes the material federal
income tax considerations to the public limited partners as a result of the
Merger and the subsequent ownership of PSI common stock for limited partners who
do not make a cash election, and that PSI is organized and operated so as to
meet the requirements for qualification as a real estate investment trust
("REIT") as defined in Sections 856 to 860 of the Internal Revenue Code of 1986,
as amended (the "Code").

     In preparing this opinion, I examined such documents as I considered
necessary or appropriate for purposes of issuing this opinion, including the
Registration Statement (including related appendices and exhibits, such as the
Agreement and Plan of Reorganization dated as of January 19, 1999 between PSI,
Merger Sub, and Partners II); and PSI's Restated Articles of Incorporation.
<PAGE>

     I also relied upon certain representations, including representations set
forth in a certificate of an officer of PSI regarding the assets, operations and
activities of PSI in the past and as to the contemplated assets, operations and
activities of PSI in the future.  I have assumed that each representation and
all other information that I reviewed is true and correct in all material
respects and will remain true and correct, that representations or statements
made to the knowledge of any person are correct without that or any similar
qualification, that all obligations imposed by any documents on the parties have
been or will be performed, and that the Registration Statement and the other
information fairly describes the past and expected future actions of the parties
as relevant to this opinion.  I have not made an independent investigation of
the accuracy or completeness of those matters.  For example, I have not
undertaken to review and determine whether each limited partnership or limited
liability company in which PSI owns an interest properly has been classified as
a "partnership" for federal income tax purposes.  Instead, I have relied upon
representations as to the status of these entities for federal income tax
purposes.  If any one or more of these entities were to be classified as an
association taxable as a corporation for federal income tax purposes, that might
preclude PSI from qualifying as a REIT for federal income tax purposes and
therefore could have a material adverse impact on this opinion.

          Based on the facts and representations and subject to the assumptions,
qualifications and limitations referred to in this letter and in the
Registration Statement, I am of the opinion that:

          (1) the discussion in the Registration Statement under the heading
     "Federal Income Tax Considerations" fairly summarizes the material federal
     income tax considerations to the public limited partners as a result of the
     Merger and the subsequent ownership of PSI common stock for limited
     partners who do not make a cash election, and

          (2) PSI is organized and operated so as to meet the requirements for
     qualification as a REIT as defined in Sections 856 to 860 of the Internal
     Revenue Code.

          PSI's qualification and taxation as a REIT depends upon both PSI's
satisfaction in the past, and PSI's ability to meet on a continuing basis in the
future, through actual annual operating and other results, the various
requirements under the Code with regard to, among other things, the sources of
its gross income, the composition of its assets, the levels of distributions to
shareholders, the diversity of its stock ownership, and the lack of C
corporation earnings and profits.  These matters may also be 
<PAGE>
 
PS Partners II, Ltd.

Page 3

affected by the tax treatment of various other entities that have been acquired
by PSI, such as Storage Trust Realty. I have relied upon representations with
respect to these matters and will not review or audit PSI's compliance with
these requirements and am not rendering an opinion on those underlying matters.
For example, I am not rendering an opinion as to whether: (1) any entity
acquired by PSI qualified as a REIT prior to the acquisition, (2) PSI satisfied
or continued to satisfy the stock ownership and gross income requirements
applicable to REITs following the PSMI Merger, or (3) whether PSI acquired or
had any current or accumulated C corporation earnings and profits as a result of
any merger. (For a discussion of certain considerations related to these
particular issues, see the discussion in the Registration Statement under the
caption "Federal Income Tax Considerations -- Consequences of the PSMI Merger on
PSI's Qualification as a REIT.") Accordingly, no assurance can be given that the
actual results of PSI's operations, the sources of its income, the nature of its
assets, the level of its distributions to shareholders, the diversity of its
share ownership, and the absence of any C corporation earnings and profits for
any given taxable year have satisfied or will satisfy the requirements under the
Code for qualification and taxation as a REIT.

          This opinion is based on my interpretation of the federal income tax
laws of the United States of America as they exist on the date of this letter
and does not cover any state, local or foreign tax issues.  I express no opinion
regarding any tax or other issues except as is specifically set forth above.
The federal income tax laws, the regulations, and the judicial and
administrative interpretation and application of those laws is subject to change
at any time.  Some issues under existing law that could significantly affect
this opinion have not been authoritatively addressed by the IRS or the courts.
Of course, any developments or changes in the law, including those reflected in
future regulations, court decisions or administrative pronouncements, may affect
the conclusions set forth in this letter, perhaps on a retroactive basis.  This
opinion is also expressly conditioned upon the truth and accuracy of the
representations, warranties, assumptions, and facts upon which I have relied in
issuing this opinion.

          This opinion represents my legal judgment as to the matters set forth
above.  An opinion of counsel does not have any binding effect and is not a
guarantee that the IRS will agree with the assumptions, analysis, or conclusions
of counsel.  Neither PSI nor Partners II has requested or will request any
ruling from the IRS about any issues presented by the Merger.  The IRS may
assert contrary positions, and a court may sustain such a contrary position if
asserted by the IRS.

          This opinion is rendered to you in connection with your participation
in the Merger and is solely for your benefit in connection with that
transaction.  This opinion 
<PAGE>

may not be relied upon by you for any other purpose, or relied upon by any other
person, firm, corporation or other entity for any purpose, without my prior
written consent. Unless required by applicable law, this opinion may not be
disclosed to or otherwise made available to any other person, firm, corporation
or other entity for any purpose, without my prior written consent. I disclaim
any obligation to advise you of any change of law that occurs, or any facts of
which I become aware, after the date of this opinion.

          I consent to the reference to me under the caption "Legal Opinions" in
the Registration Statement and to the filing of this opinion as an exhibit to
the Registration Statement or amendments to the Registration Statement.  In
giving this consent, however, I do not admit that I am an "expert" within the
meaning of the Securities Act of 1933, as amended.

                               Very truly yours,


                              /s/ A. Timothy Scott

Ladies and Gentlemen:

       If the Exchange Agent has not received your properly completed Cash
Election Form by the Election Deadline (as defined in Instruction A), you will
receive PSI Common Stock in the Merger.

       The undersigned hereby certifies that this Election covers all of the
Units registered in the name of the undersigned and either (i) beneficially
owned by the undersigned, or (ii) owned by the undersigned in a representative
or fiduciary capacity for a particular beneficial owner or for one or more
beneficial owners, except as otherwise permitted pursuant to Instruction F(4).
A Unitholder may not make a cash election as to less than all of the Units
beneficially owned by such Unitholder.

F. SPECIAL CONDITIONS

   (1) Revocation of Election.  An election may be revoked by the person or
persons making such election by a written notice signed and dated by such person
or persons and received by the Exchange Agent prior to the Election Deadline,
identifying the name of the registered holder of the Units subject to such
Election and the total number of Units owned by the beneficial owner.

   (2) Nullification of Election.  All Cash Election Forms will be void and of
no effect if the Merger is not consummated.

   (3) Elections Subject to Election Procedures.  All Elections are subject to
the Election Procedures set forth in the Merger Agreement and described in the
Information Statement and Prospectus under the caption "The Merger -- Cash
Election Procedure" and to the other terms and conditions set forth thereunder
and hereunder, including the documents incorporated herein by reference.

   (4) Units Held by Nominees, Trustees or other Representatives.  Holders of
record of Units who hold such Units as nominees, trustees or in other

<PAGE>
 
Forms covering the aggregate number of Units held by such Representative for the
beneficial owners for whom the Representative is making an Election, provided,
that such Representative certifies that each such Cash Election Form covers all
the Units held by such Representative for a particular beneficial owner.  Any
Representative who makes an Election or a Non-Election may be required to
provide the Exchange Agent with such documents and/or additional certifications,
if requested, in order to satisfy the Exchange Agent that such Representative
holds such Units for a particular beneficial owner of such Units.  If any Units
held by a Representative are not covered by an effective Cash Election Form,
they will be exchanged for PSI Common Stock.

G. GENERAL

   (1) Execution and Delivery.  In order to make an effective Election, you must
correctly fill in the Execution Section of this Cash Election Form.  After
dating and signing it, you are responsible for its delivery to the Exchange
Agent at the address set forth on the first page of this Cash Election Form by
the Election Deadline.  YOU MAY CHOOSE ANY METHOD TO DELIVER THIS CASH ELECTION
FORM; HOWEVER, YOU ASSUME ALL RISK OF NON-DELIVERY.  IF YOU CHOOSE TO USE THE
MAIL, WE RECOMMEND THAT YOU USE REGISTERED MAIL, RETURN RECEIPT REQUESTED.

   (2) Signatures.  Except as otherwise permitted below, you must sign this Cash
Election Form exactly the way your name appears on the label in Box A
(Registered Holder Information).  If the Units are owned by two or more persons,
each must sign exactly as his or her name appears on the label in Box A
(Registered Holder Information).  If the Units have been assigned by the
registered owner, this Cash Election Form should be signed in exactly the same
way as the name of the assignee appearing on the transfer documents.  See
Instruction G(5)(a).

   (3) Notice of Defects; Resolution of Disputes.  None of the Partnership, PSI
and the Exchange Agent will be under any obligation to notify you or anyone else
that the Exchange Agent has not received a properly completed Cash Election Form
or that any Cash Election Form submitted is defective in any way.

       Any and all disputes with respect to Cash Election Forms or to Elections
made in respect of Units (including but not limited to matters relating to the
Election Deadline, time limits, effectiveness of any Elections, will be resolved
by PSI and its decision will be conclusive and binding on all concerned.  PSI
may delegate this function to the Exchange Agent in whole or in part.  PSI or
the Exchange Agent shall have the absolute right in its sole discretion to
reject any and all Cash Election Forms which are deemed by either of them to be
not in proper form or to waive any immaterial irregularities in any Cash
Election Form.

   (4) Issuance of Payment Check(s).  If the Payment Check(s) are to be issued
in the name of the registered holder(s) as it appears on the label in Box A
(Registered Holder Information), no guarantee of the signature on the Cash
Election Form is required.  For corrections in name and change in name not
involving changes in ownership, see Instruction G(5)(b).

   (5) Issuance of Payment Check(s) in Different Names.  If the Payment Check(s)
are to be issued in the name of someone other than the registered holder(s) as
it appears on the label in Box A (Registered Holder Information), you must
follow the guidelines below.  Note that in each circumstance listed below,
unitholder(s) must have signature(s) guaranteed in Box C (Signature Guarantee)
and complete Box E (Special Payment Instructions).

     (a) Transferee's Signature and Guarantee.  The Cash Election Form must be
   signed by the transferee or assignee or his or her agent, and should not be
   signed by the transferor or assignor.  See Box B (Sign Here).  The signature
   of such transferee or assignee must be medallion guaranteed by an eligible
   guarantor institution as provided below.

                  DEFINITION OF ELIGIBLE GUARANTOR INSTITUTION

       Generally an eligible guarantor institution, as defined in Rule 17Ad-15
   of the regulations of the Securities and Exchange Commission, means:  (i)
   banks (as that term is defined in Section 3(a) of the Federal Deposit
   Insurance Act); (ii) brokers, dealers, municipal securities dealers,
   municipal securities brokers, government securities dealers, and government
   securities brokers, as those terms are defined under the Securities Exchange
   Act of 1934; (iii) credit unions (as that term is defined in Section
   19(b)(1)(A) of the Federal Reserve Act); (iv) national securities exchanges,
   registered securities associations, clearing agencies, as those terms are
   used under the Securities Exchange Act of 1934; and (v) savings associations
   (as that term is defined in Section 3(b) of the Federal Deposit Insurance
   Act).

     (b) Correction of or Change in Name.  For a correction of name or for a
   change in name which does not involve a change in ownership, proceed as
   follows.  For a change in name by marriage, etc., the Cash Election Form
   should be signed, e.g., "Mary Doe, now by marriage Mary Jones."  For a
   correction in name, the Cash Election Form should be signed, e.g., "James E.
   Brown, incorrectly inscribed as J.E. Brown."  The signature in each case
   should be guaranteed in the manner described in Instruction G(5)(a) above and
   Box E (Special Payment Instructions) should be completed.

     You should consult your own tax advisor as to any possible tax consequences
   resulting from the issuance of Payment Check(s) in a name different from that
   of the registered holder(s) of the Units.

   (6) Supporting Evidence.  In case any Cash Election Form is executed by an
agent, attorney, administrator, executor, guardian, trustee or any person in any
other fiduciary or representative capacity, or by an officer of a corporation on
behalf of the corporation, there must be submitted (with the Cash Election Form)
documentary evidence of appointment and authority to act in such capacity
(including court orders and corporate resolutions when necessary), as well as
evidence of the authority of the person making such execution to assign, sell or
transfer the Units.  Such documentary evidence of authority must be in form
satisfactory to the Exchange Agent.

   (7) Special Mailing Instructions.  The Payment Check(s) will be mailed to the
address of the registered holder(s) as indicated in Box A (Registered Holder
Information), unless instructions to the contrary are given in Box F (Special
Mailing Instructions).

                                       3
<PAGE>
 
   (8) Federal Income Tax Withholding.  Under Federal income tax law, the
Exchange Agent is required to file a report with the Internal Revenue Service
disclosing any payments of cash being made to each holder of Units pursuant to
the Merger Agreement.  In order to avoid backup withholding of Federal income
tax on any cash received upon the surrender of Units, a holder thereof must,
unless an exemption applies, provide the Exchange Agent with his or her correct
taxpayer identification number ("TIN") on Substitute Form W-9, which is part of
this Cash Election Form (Box D), and certify, under penalties of perjury, that
such number is correct and that such holder is not otherwise subject to backup
withholding.  If the correct TIN and certifications are not provided, a $50
penalty may be imposed by the Internal Revenue Service and payments made for
surrender of Units may be subject to backup withholding of 31%.  In addition, if
a holder makes a false statement that results in no imposition of backup
withholding, and there was no reasonable basis for making such a statement, a
$500 penalty may also be imposed by the Internal Revenue Service.

       Backup withholding is not an additional Federal income tax.  Rather, the
Federal income tax liability of a person subject to backup withholding will be
reduced by the amount of such tax withheld.  If backup withholding results in an
overpayment of income taxes, a refund may be obtained from the Internal Revenue
Service.

       The TIN that must be provided on the Substitute Form W-9 is that of the
registered holder(s) of the Units at the effective time of the Merger.  The TIN
for an individual is his or her social security number.  The box in Part II of
the Substitute Form W-9 may be checked if the person surrendering the Units has
not been issued a TIN and has applied for a TIN or intends to apply for a TIN in
the near future.  If the box in Part II has been checked, the person
surrendering the Units must also complete the Certificate of Awaiting Taxpayer
Identification Number below in order to avoid backup withholding.
Notwithstanding that the box in Part II is checked (and the Certificate of
Awaiting Taxpayer Identification Number is completed), the Exchange Agent will
withhold 31% on all cash payments with respect to surrendered Units made prior
to the time it is provided with a properly certified TIN.

       Exempt persons (including, among others, corporations) are not subject to
backup withholding.  A foreign individual may qualify as an exempt person by
submitting Form W-8 or a substitute Form W-8, signed under penalties of perjury,
certifying to such person's exempt status.  A form of such statement can be
obtained from the Exchange Agent.  A unitholder should consult his or her tax
advisor as to such holder's qualification for an exemption from backup
withholding and the procedure for obtaining such exemption.

       The signature and date provided on the Substitute Form W-9 will serve to
certify that the TIN and withholding information provided in this Cash Election
Form are true, correct and complete.

   (9) Assistance and Information.  If you need assistance to complete this Cash
Election Form or wish to obtain additional copies of the Cash Election Form and
the Information Statement and Prospectus, please contact the Exchange Agent at
the addresses and telephone number set forth on the first page of this Cash
Election Form.  If you have questions, please contact PSI, Investor Services
Department, at the address and telephone numbers set forth on the first page of
this Cash Election Form.

H. DELIVERY OF PAYMENT CHECKS

       As soon as practicable after the Merger becomes effective, the Exchange
Agent will make the payments of cash to be received by holders of Units or their
designees in accordance with the Election Procedures.  The Exchange Agent will
thereafter issue and mail to you a check for any cash to which you are entitled.

          After the Merger, holders of Units that were converted into shares of
PSI Common Stock, without any further action, will be entitled to receive
certificates representing the number of whole shares of PSI Common Stock into
which Units will have been converted and cash payment in lieu of fractional
share interests, if applicable.  As soon as practicable after the Merger, the
Exchange Agent will send the certificates for the PSI Common Stock to each
holder of Units whose Units have been converted into shares of PSI Common Stock.
HOLDERS OF UNITS WHO INTEND TO RECEIVE PSI COMMON STOCK IN THE MERGER DO NOT
NEED TO TAKE ANY ACTION TO RECEIVE THEIR RESPECTIVE CERTIFICATES REPRESENTING
THE PSI COMMON STOCK.
