            SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

directors and executive officers, and persons who own more than 10% of any
registered class of the Company's equity securities ("10% owners"), to file with
the Securities and Exchange Commission ("SEC") initial reports (on Form 3) of
ownership of the Company's equity securities and to file subsequent reports (on
Form 4 or Form 5) when there are changes in such ownership.  The due dates of
such reports are established by statute and the rules of the SEC.  Based on a
review of the reports submitted to the Company, the Company believes that, with
respect to the fiscal year ended December 31, 1996, (i) Uri P. Harkham, a
director of the Company, filed one report on Form 5 which disclosed two
transactions that were not timely reported and (ii) Obren B. Gerich, an

Item 11.  Executive Compensation
          ----------------------

Compensation of Executive Officers

     Prior to November 16, 1995, the effective date of the PSMI Merger (the
"Effective Date"), the Company did not pay cash compensation to its executive
officers (other than the directors' fees and expenses paid to Harvey Lenkin--see
"Compensation of Directors" below).

     Prior to the Effective Date, the Company had an advisory contract with
Public Storage Advisers, Inc. (the "Adviser") pursuant to which the Company paid
advisory fees to the Adviser, and the Company had management agreements with
PSMI and Public Storage Commercial Properties Group, Inc. ("PSCP") pursuant to
which the Company paid fees to PSMI and PSCP.  The Adviser, PSMI and (prior to
the Effective Date) PSCP were controlled by B. Wayne Hughes and members of his
family.

     On the Effective Date, the Advisory Contract and the Management Agreement
were extinguished, and the Company became self-administered and self-managed.
Accordingly, beginning on the Effective Date, the Company began to pay cash
compensation to its executive officers.

     The following table sets forth certain information concerning the annual
and long-term compensation paid to (i) B. Wayne Hughes, the Company's Chief
Executive Officer, the four most highly compensated persons who were executive
officers of the Company on December 31, 1996 and one former executive officer of
the Company who would have been among the four most highly compensated executive
officers had he been an executive officer of the Company on December 31, 1996
(the "Named Executive Officers") for 1996 and (2) to B. Wayne Hughes for 1995
for the period beginning on the Effective Date and ending on December 31, 1995
(the Company has no executive officer who earned $100,000 or more from the
Company for such period).

Compensation of Directors

     Each of the Company's directors, other than B. Wayne Hughes, receives
director's fees of $19,000 per year plus $450 for each meeting attended.  In
addition, each of the members of the Audit Committee (other than the chairman,
who receives $900 per meeting) receives $450 for each meeting of the Audit
Committee attended.  The policy of the Company is to reimburse directors for
reasonable expenses.  Directors who are not officers or employees of the Company
("Outside Directors") also receive grants of options under the Company's 1996
Stock Option and Incentive Plan (and B. Wayne Hughes and Harvey Lenkin are
eligible to receive grants of options and/or restricted stock thereunder) as
described below.  (See "Compensation of Executive Officers--Option Grants in
Last Fiscal Year" for information on the option grants to Harvey Lenkin in 1996
under the Company's 1994 Stock Option Plan and 1996 Stock Option and Incentive
Plan.)  Under the 1996 Stock Option and Incentive Plan, each new Outside
Director is, upon the date of his or her initial election to serve as an Outside
Director, automatically granted non-qualified options to purchase 15,000 shares
of Common Stock.  In addition, after each annual meeting of shareholders, each
Outside Director then duly elected and serving is automatically granted, as of
the date of such annual meeting, non-qualified options to purchase 2,500 shares
of Common Stock, so long as such person has attended, in person or by telephone,
at least 75% of the meetings held by the Board of Directors during the
immediately preceding calendar year.

Employment Agreement

     B. Wayne Hughes, the Chairman of the Board and Chief Executive Officer of
the Company, entered into an employment agreement with the Company in November
1995 in connection with the PSMI Merger.  This agreement is for a term of five
years and provides for annual compensation of $60,000.

          COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     The Company does not have a compensation committee.  The Company's stock
option and incentive plans, under which executive officers are eligible to
receive options and/or restricted stock, are administered by the Audit
Committee.  The members of the Audit Committee are Robert J. Abernethy and
William C. Baker.

     Messrs. Hughes and Lenkin, who are executive officers of the Company, are
members of the Board of Directors.  Mr. Hughes is a director and the Chief
Executive Officer of the six Public Storage REITs (and during all or part of
1996, Mr. Hughes was a director and the Chief Executive Officer of Properties 9,
Properties 10, Properties 12, Properties 14, Properties 15, PSBP, PPY, PPY2 and
PPY3).  Until June 1996, Mr. Hughes also was the Chief Executive Officer and a
director of SPI, of which Mr. Lenkin was the President and a director.  None of
the six Public Storage REITs has (nor did Properties 9, Properties 10,
Properties 12, Properties 14, Properties 15, PSBP, PPY, PPY2, PPY3 or SPI have)
a compensation committee.

Certain Relationships and Related Transactions

     Mergers with Related Companies.  During 1996 and 1997, 10 of the Merged
Public Storage REITS were merged with and into the Company.  The Company's
executive officers and members of their families received the following
consideration in nine of these mergers:

     Each of these mergers was approved by the shareholders and the
disinterested directors of the respective Merged Public Storage REIT and the
disinterested directors of the Company.

     In April 1997, the Company and Properties 16 agreed, subject to certain
conditions, to merge.  Upon the merger, each outstanding share of Properties 16
common stock series A (other than shares held by the Company or by holders of
Properties 16 common stock series A ("Properties 16 Series A Shareholders") who
have properly exercised dissenters' rights under California law ("Properties 16
Dissenting Shares")) would be converted into the right to receive cash, the
Company's Common Stock or a combination of the two, as follows:  (i) with
respect to a certain number of shares of Properties 16 common stock series A
(not to exceed 20% of the outstanding Properties 16 common stock series A, less
any Properties 16 Dissenting Shares), upon a Properties 16 Series A
Shareholder's election, $20.76 in cash, subject to reduction as described below
or (ii) that number (subject to rounding) of shares of the Company's Common
Stock determined by dividing $20.76, subject to reduction as described below, by
the average of the per share closing prices on the New York Stock Exchange
("NYSE") of the Company's Common Stock during the 20 consecutive trading days
ending on the fifth trading day prior to the special meeting of the shareholders
of Properties 16.  The consideration paid by the Company to the Properties 16
Series A Shareholders in the merger will be reduced by the amount of cash
distributions required to be paid by Properties 16 to the Properties 16 Series A
Shareholders prior to completion of the merger (estimated at $.72 per share) in
order to satisfy Properties 16's REIT distribution requirements ("Properties 16
Required REIT Distributions").  The consideration received by the Properties 16
Series A Shareholders in the merger, however, along with any Properties 16
Required REIT Distributions, will not be less than $20.76 per share of
Properties 16 common stock series A, which amount represents the interest of the
Properties 16 Series A Shareholders in the market value of Properties 16's real
estate assets at March 17, 1997 (based on an independent appraisal) and the
interest of the Properties 16 Series A Shareholders in the estimated value of
its other assets at June 30, 1997.  Additional distributions would be made to
the Properties 16 Series A Shareholders to cause Properties 16's estimated net
asset value allocable to the Properties 16 Series A Shareholders as of the date
of the merger to be substantially equivalent to $20.76 per share.  Upon the
merger, each share of Properties 16 common stock series B and common stock
series C would be converted into the right to receive $11.82 in the Company's
Common Stock (valued as in the case of the Properties 16 common stock series A)
plus any Properties 16 Required REIT distributions payable to the holders of the
Properties 16 common stock series B (estimated at $.72 per share).  The
Properties 16 common stock held by the Company will be canceled in the merger.
The merger was approved by the disinterested directors of Properties 16 and is
conditioned on, among other requirements, approval by the shareholders of
Properties 16 and the disinterested directors of Properties 16 and receipt of a
satisfactory fairness opinion by Properties 16.  Properties 16 is one of the
finite-life REITs organized by an affiliate of PSMI.  Properties 16's common
stock series A is listed on the American Stock Exchange.  Properties 16's common
stock series B and C is owned by the Company and certain executive officers of
the company and members of their families.  Properties 16 owns 20 mini-
warehouses, one business park and one property that combines mini-warehouse and
business park space.  There are 2,962,348 shares of Properties 16 common stock
series A and 1,180,793.2 shares of Properties 16 common stock series B and C.
As a result of the PSMI Merger, the Company is Properties 16's mini-warehouse
property operator.  The Company owns 34.98% of the total combined shares of
Properties 16 common stock series A, B and C (the "Total Properties 16 Common
Stock").  The Company's executive officers have significant relationships with
Properties 16.  B. Wayne Hughes owns 4.46% of the Total Properties 16 Common
Stock, members of B. Wayne Hughes' family own an additional 1.54% of the Total
Properties 16 Common Stock and the Company's executive officers, excluding
Hughes, and members of their families own an additional 2.51% of the Total
Properties 16 Common Stock.

     In April 1997, the Company and Properties 17 agreed, subject to certain
conditions, to merge. Upon the merger, each outstanding share of Properties 17
common stock series A (other than shares held by the Company or by holders of
Properties 17 to common stock series A ("Properties 17 Series A Shareholders")
who have properly exercised dissenters' rights under California law ("Properties
17 Dissenting Shares")) would be converted into the right to receive cash, the
Company's Common Stock or a combination of the two, as follows: (i) with respect
to a certain number of shares of Properties 17 common stock series A (not to
exceed 20% of the outstanding Properties 17 common stock series A, less any
Properties 17 Dissenting Shares), upon a Properties 17 Series A Shareholder's
election, $19.63 in cash, subject to reduction as described below or (ii) that
number (subject to rounding) of shares of the Company's Common Stock determined
by dividing $19.63, subject to reduction as

described below, by the average of the per share closing prices on the NYSE of
the Company's Common Stock during the 20 consecutive trading days ending on the
fifth trading day prior to the special meeting of the shareholders of Properties
17. The consideration paid by the Company to the Properties 17 Series A
Shareholders in the merger will be reduced by the amount of cash distributions
required to be paid by Properties 17 to the Properties 17 Series A Shareholders
prior to completion of the merger (estimated at $.81 per share) in order to
satisfy Properties 17's REIT distribution requirements ("Properties 17 Required
REIT Distributions"). The consideration received by the Properties 17 Series A
Shareholders in the merger, however, along with any Properties 17 Required REIT
Distributions, will not be less than $19.63 per share of Properties 17 common
stock series A, which amount represents the interest of the Properties 17 Series
A Shareholders in the market value of Properties 17's real estate assets at
March 17, 1997 (based on an independent appraisal) and the interest of the
Properties 17 Series A Shareholders in the estimated value of its other assets
at June 30, 1997. Additional distributions would be made to the Properties 17
Series A Shareholders to cause Properties 17's estimated net asset value
allocable to the Properties 17 Series A Shareholders as of the date of the
merger to be substantially equivalent to $19.63 per share. Upon the merger, each
share of Properties 17 common stock series B and common stock series C would be
converted into the right to receive $10.26 in the Company's Common Stock (valued
as in the case of the Properties 17 common stock series A) plus any Properties
17 Required REIT distributions payable to the holders of the Properties 17
common stock series B (estimated at $.81 per share). The Properties 17 common
stock held by the Company will be canceled in the merger. The merger was
approved by the disinterested directors of Properties 17 and is conditioned on,
among other requirements, approval by the shareholders of Properties 17 and the
disinterested directors of Properties 17 and receipt of a satisfactory fairness
opinion by Properties 17. Properties 17 is one of the finite-life REITs
organized by an affiliate of PSMI. Properties 17's common stock series A is
listed on the American Stock Exchange. Properties 17's common stock series B and
C is owned by the Company and certain executive officers of the Company and
members of their families. Properties 17 owns 16 mini-warehouses, one business
park and two properties that combine mini-warehouse and business park space.
There are 2,776,023 shares of Properties 17 common stock series A and 1,245,791
shares of Properties 17 common stock series B and C. As a result of the PSMI
Merger, the Company is Properties 17's mini-warehouse property operator. The
Company owns 41.08% of the total combined shares of Properties 17 common stock
series A, B and C (the "Total Properties 17 Common Stock"). The Company's
executive officers have significant relationships with Properties 17. B. Wayne
Hughes owns 0.02% of the Total Properties 17 Common Stock, members of B. Wayne
Hughes' family own an additional 0.94% of the Total Properties 17 Common Stock
and the Company's executive officers, excluding Hughes, and members of their
families own an additional 1.76% of the Total Properties 17 Common Stock.

     In April 1997, the Company and Properties 19 agreed, subject to certain
conditions, to merge.  Upon the merger, each outstanding share of Properties 19
common stock series A (other than shares held by the Company or by holders of
Properties 19 common stock series A ("Properties 19 Series A Shareholders") who
have properly exercised dissenters' rights under California law ("Properties 19
Dissenting Shares")) would be converted into the right to receive cash, the
Company's Common Stock or a combination of the two, as follows:  (i) with
respect to a certain number of shares of Properties 19 common stock series A
(not to exceed 20% of the outstanding Properties 19 common stock series A, less
any Properties 19 Dissenting Shares), upon a Properties 19 Series A
Shareholder's election, $16.72 in cash, subject to reduction as described below
or (ii) that number (subject to rounding) of shares of the Company's Common
Stock determined by dividing $16.72, subject to reduction as described below, by
the average of the per share closing prices on the NYSE of the Company's Common
Stock during the 20 consecutive trading days ending on the fifth trading day
prior to the special meeting of the shareholders of Properties 19.  The
consideration paid by the Company to the Properties 19 Series A Shareholders in
the merger will be reduced by the amount of cash distributions required to be
paid by Properties 19 to the Properties 19 Series A Shareholders prior to
completion of the merger (estimated at $.35 per share) in order to satisfy
Properties 19's REIT distribution requirements ("Properties 19 Required REIT
Distributions").  The consideration received by the Properties 19 Series A
Shareholders in the merger, however, along with any Properties 19 Required REIT
Distributions, will not be less than $16.72 per share of Properties 19 common
stock series A, which amount represents the interest of the Properties 19 Series
A Shareholders in the market value of Properties 19's real estate assets at
March 17, 1997 (based on an independent appraisal) and the interest of the
Properties 19 Series A Shareholders in the estimated value of its other assets
at June 30, 1997.  Additional distributions would be made to the Properties 19
Series A Shareholders to cause Properties 19's estimated net asset value
allocable to the Properties 19 Series A Shareholders as of the date of the
merger to be substantially equivalent to $16.72 per share.  Upon the merger,
each share of Properties 19 common stock series B and common stock 

                                      -9-

series C would be converted (or deemed to be converted) into the right to
receive $1.41 in the Company's Common Stock (valued as in the case of the
Properties 19 common stock series A) plus any Properties 19 Required REIT
distributions payable to the holders of the Properties 19 common stock series B
(estimated at $.35 per share). The Properties 19 common stock held by the
Company will be canceled in the merger. The merger was approved by the
disinterested directors of Properties 19 and is conditioned on, among other
requirements, approval by the shareholders of Properties 19 and the
disinterested directors of Properties 19 and receipt of a satisfactory fairness
opinion by Properties 19. Properties 19 is one of the finite-life REITs
organized by an affiliate of PSMI. Properties 19's common stock series A is
listed on the American Stock Exchange. Properties 19's common stock series B and
C is owned by the Company. Properties 19 owns 12 mini-warehouses, one business
park and one property that combines mini-warehouse and business park space.
There are 3,023,371 shares of Properties 19 common stock series A and 1,085,690
shares of Properties 19 common stock series B and C. As a result of the PSMI
Merger, the Company is Properties 19's mini-warehouse property operator. The
Company owns 42.15% of the total combined shares of Properties 19 common stock
series A, B and C (the "Total Properties 19 Common Stock"). The Company's
executive officers have significant relationships with Properties 19. B. Wayne
Hughes owns 0.04% of the Total Properties 19 Common Stock and members of B.
Wayne Hughes' family own an additional 0.1% of the Total Properties 19 Common

commenced (i) a tender offer to acquire up to 6,000 of the limited partnership
units in Public Storage Properties IV, Ltd., a California limited partnership
("Properties IV") at a price of $447 per unit in cash and (ii) a tender offer to
acquire up to 6,600 of the limited partnership units in Public Storage

Company an option to acquire from him, at his cost, the units tendered in each
of the tender offers, at any time after May 2, 1998 (12 months from the
expiration date of the tender offers).

     Purchase of Common Stock by Officers and Directors Pursuant to Shelf
Registration Statement.  The Company's directors have authorized the Company to
offer and sell shares of Common Stock (collectively, the "Director and Officer
Shares") pursuant to the prospectus included in the Company's shelf registration
