PROSPECTUS SUPPLEMENT
(TO PROSPECTUS DATED DECEMBER 4, 1996)
 
                               2,200,000 SHARES
 
                             STORAGE TRUST REALTY
 
                                 COMMON SHARES
 
                               ----------------
 
  Storage Trust Realty (the "Company") is a self-administered and self-managed
real estate investment trust (a "REIT") engaged in the self-storage business.
The Company, which began operations through a predecessor in 1974, owns,
manages, acquires and develops self-storage facilities primarily in the
Southern, Mid-Atlantic, Midwestern and Western regions of the United States.
At September 30, 1997, the Company owned or operated a geographically diverse
portfolio of 193 self-storage facilities (the "Facilities") located in 16
states and containing an aggregate of approximately 10.1 million net rentable
square feet.
 
  All of the common shares of beneficial interest of the Company, $.01 par
value per share (the "Common Shares"), offered hereby are being offered by the
Company (the "Offering"). The Common Shares are listed on the New York Stock
Exchange (the "NYSE") under the symbol "SEA." On October 15, 1997, the last
reported sale price of the Common Shares on the NYSE was $24 13/16. See "Price
Range of Common Shares and Distribution History."
 
  To ensure that the Company maintains its qualification as a REIT for federal
income tax purposes, it expects to continue to pay regular quarterly
distributions to its shareholders. In addition, the Declaration of Trust of
the Company restricts the ownership of more than 6% of the Common Shares by
any person or affiliated group, with certain exceptions.
 
  The 2,200,000 Common Shares offered hereby will be purchased from the
Company by BancAmerica Robertson Stephens (the "Underwriter") at a price of
$23.70 per share for an aggregate purchase price of $52,140,000. The Company
has granted the Underwriter an option for 30 days to purchase up to 330,000
additional Common Shares at the same price solely to cover over-allotments. If
such option is exercised in full, the total proceeds to the Company will be
$59,961,000, before deducting expenses payable by the Company (estimated at
$150,000).
 
  The Common Shares may be offered by the Underwriter from time to time in one
or more transactions (which may involve block transactions) on the NYSE, in
the over-the-counter market, through negotiated transactions or otherwise at
market prices prevailing at the time of the sale or at prices otherwise
negotiated. See "Underwriting."

    AND   EXCHANGE  COMMISSION,  NOR  HAS  THE  SECURITIES   AND  EXCHANGE
       COMMISSION  PASSED  UPON  THE   ACCURACY  OR  ADEQUACY  OF  THIS

  The following discussion is qualified in its entirety by the more detailed
information appearing elsewhere in this Prospectus Supplement, the
accompanying Prospectus or incorporated therein by reference. Unless indicated
otherwise, the information contained in this Prospectus Supplement (i) assumes
no exercise of the Underwriter's over-allotment option and (ii) except as
otherwise indicated, is presented as of September 30, 1997. All references to
the "Company" in this Prospectus Supplement and the accompanying Prospectus or
incorporated therein by reference shall be deemed to include the Company, its
predecessors, and those entities of which the Company controls or owns a
majority of the economic interests, unless the context indicates otherwise.
 
                                  THE COMPANY
 
  The Company is a self-administered and self-managed REIT engaged in the
self-storage business. As of September 30, 1997, the Company owned or operated
a geographically diverse portfolio of 193 self-storage Facilities in 16 states
throughout the Southern, Mid-Atlantic, Midwestern and Western regions of the
United States, containing an aggregate of approximately 10.1 million net
rentable square feet. The Facilities offer a broad range of features and
amenities to customers, including uniformed customer-service-oriented facility
managers, door alarms, lighting systems, video cameras, twenty-four hour
computer-controlled access, climate-controlled storage spaces, attractive
buildings and wide drive aisles.
 
  The Company believes that it is one of the largest owners and operators of
self-storage facilities in the United States. The Company wholly owns 181 of
the Facilities and owns an interest in two of the Facilities through joint
ventures. Eleven of the Facilities are managed by Storage Realty Management
Co. (the "Management Company"), including one of the joint venture Facilities.
Since the Company's initial public offering in November 1994 (the "IPO"), the
Company has acquired a total of 128 Facilities and exchanged 18 Facilities,
representing a net total investment (defined as the original purchase price
plus all capitalized costs related to those properties) of approximately $295
million. This represents an increase in the number of Facilities which it owns
and/or operates of 119%, and an increase in net rentable square footage of
153%, since the IPO. From January 1, 1997 to September 30, 1997, the Company
acquired 32 self-storage facilities for a combined purchase price of $84.5
million. In two separate transactions during 1997, the Company exchanged 16
facilities comprising approximately 689,000 net rentable square feet for ten
facilities (included in the acquisition totals above). These acquisitions and
exchanges were strategically chosen to increase the Company's presence in
certain existing markets, to access attractive new markets or to decrease the
Company's presence in markets perceived to have limited opportunity for
growth. The Company intends to continue to grow through acquisitions,
expansions, conversions and developments. The Company believes that the
recently acquired Facilities as well as self-storage facilities which may be
acquired or developed in the future have been and can be efficiently
integrated into its operations due to the Company's centralized operating
procedures and management information systems.
 
  Management believes that the Company's future growth will be determined in
part by certain characteristics of the self-storage industry, including the
(i) low level of consumer sensitivity to rent increases, (ii) lack of
concentrated ownership, (iii) shortage of skilled operators, (iv) economies of
scale and (v) increasing customer base. Based on information published in
Inside Self-Storage (August 1997) , the ten largest operators of self-storage
properties control approximately 3,160 facilities, which the Company believes
constitute approximately 13% of all of the self-storage facilities in the
United States. Of the remaining self-storage facilities in the United States,
most are owned and operated by single-site owners or other small operators.
The Company believes that the fragmented ownership and shortage of skilled
operators in the self-storage industry will continue to lead to significant
opportunities for growth through acquisitions in the near term for those
participants in the self-storage industry who possess sufficient capital
resources and effective operational skills.
 
  The Company intends to increase cash available for distribution per share
and enhance shareholder value by (i) managing the Facilities and expanding
them where economically feasible, (ii) acquiring additional self-storage
facilities, (iii) converting other commercial real estate into self-storage
facilities and (iv) developing new self-storage facilities.

  In November 1994, the Company completed its IPO of 5,859,282 Common Shares,
which resulted in net proceeds of approximately $92.1 million. In June 1995,
the Company completed a second public offering of 2,875,000 Common Shares,
which resulted in net proceeds of approximately $53.6 million. In July 1996,
the Company completed a third public offering of 4,140,000 Common Shares,
which resulted in net proceeds of approximately $78.9 million.
 
HISTORY OF BHC
 
  Burnam Holding Companies Co. and certain of its affiliates, the Company's
predecessor (collectively, "BHC"), developed one of the first self-storage
facilities in the Midwestern United States in 1974. Between 1974 and the IPO,
the Company's management, through BHC, developed 36 self-storage facilities
and oversaw the acquisition, development and management of more than 6.5
million square feet of self-storage facilities. The Company believes that,
over the last 20 years, BHC has historically been at the leading edge of many
innovations in the self-storage industry such as:
 
  .  Developing computer software packages exclusively for self-storage
     (1978)--Prior to the mid 1980's there were no nationally established
     software vendors for the industry. Driven by the need to manage multiple
     facilities from a central office location, BHC developed its own
     application software system and has subsequently developed three
     successive generations of this software. The Company employs three full-
     time employees in its management information systems department to
     support the on-site managers.
 
  .  Establishing an industry lobby (1978)--Many states did not have statutes
     regulating the collection of delinquent accounts for the self-storage
     industry. BHC helped form industry trade groups which lobbied for and
     passed self-storage legislation in Missouri, Florida and Mississippi.
 
  .  Developing standardized manuals and training guides (1981)--As BHC grew
     and began to operate in many locations and different states, training
     and retaining the proper personnel became increasingly important. In
     response, BHC created a comprehensive training manual and training
     programs for its facility managers.
 
  .  Introducing climate-controlled storage (early 1980's)--As BHC began
     development on the Gulf Coast, the need for a low humidity storage
     environment became apparent. In the following years, BHC found a growing
     demand for this premium product. BHC actively converted existing regular
     storage space to climate control and added new climate-controlled
     storage space additions to existing facilities.
 
  .  Installing computer-controlled access gates (1982)--BHC began
     incorporating computer-controlled access gates into its operations in
     recognition of customer concerns regarding convenience, safety and
     security.
 
  .  Conducting facility managers' conventions (1984)--BHC held what it
     believes was the first facility managers' convention in the self-storage
     industry. In a retreat style format, the managers convention is now held
     every 18 months, and, in the Company's opinion, has proven an excellent
     tool for training and team building exercises.
 
  .  Establishing direct marketing (1990)--BHC developed the "40 Hit List"
     marketing program for its facility managers addressing specific
     techniques such as effective telephone sales and community marketing.
     BHC believes that its management techniques for self-storage facilities,
     as well as its conservative approach to the development of new
     properties and ability to acquire existing properties, enabled BHC to
     continue to grow its business during difficult times.
 
  .  Establishing Storage Trust University (1994)--The Company developed a
     centralized training academy for storage managers in the self-storage
     industry.
 
 
                                      S-4
<PAGE>
 
  .  Installing SiteGard Video Surveillance Systems (1996)--The Company
     developed and installed its first property security camera display and
     system. By the end of 1998, all of the Facilities sites will be equipped
     with SiteGard.
 
  .  Partnering with U-Haul Truck Rentals (1996)--The Company became the
     world's largest dealer of U-Haul Rental trucks in an exclusive marketing
     agreement. This synergistic arrangement has resulted in more units being
     rented and additional income from product sales such as boxes and moving
     supplies.
 
  .  Establishing Site Link (1997)--E-mail network to all Company locations
     was established. Site Link provides for the rapid transmission of
     selected operational documents, thus providing for more immediate
     decision making.
 
BUSINESS OBJECTIVES AND OPERATING STRATEGIES
 
 Business Objectives
 
  The Company's primary objectives are to increase cash available for
distribution and enhance shareholder value. These objectives are accomplished
by (i) managing the Facilities and expanding them where economically feasible,
(ii) acquiring existing self-storage facilities, (iii) converting other
commercial real estate into self-storage facilities and (iv) developing new
self-storage facilities. The Company's strategies for accomplishing these
objectives are:
 
 Internal Growth Strategies
 
  The Company's internal growth strategy is to increase cash flow at the
Facilities (and any additional facilities hereafter acquired) by (i)
aggressively increasing rents on a regular basis, (ii) containing costs and
improving operating leverage and (iii) selectively expanding the Facilities,
which includes the addition of climate controlled space.
 
  .  Increasing Rents--Revenues are increased through the use of sales and
     marketing programs that are customized for each location and an
     aggressive leasing program. The Company pursues an objective of being a
     price leader in its local markets and will attempt to increase rents at
     all of the Facilities throughout the year. The Company has a general
     policy that, as occupancy of all same-size units at a particular
     Facility nears 90%, it will consider increasing rents applicable to
     those units. The Company plans to continue this strategy at the
     Facilities and to implement it at facilities that may be acquired or
     developed in the future.
 
  .  Containing Costs and Improving Operating Leverage--The Company seeks to
     increase cash flow by containing facility operating expenses and
     spreading corporate overhead expense over an increasing number of
     facilities. The Company believes that new facilities can be added to the
     portfolio with very little additional overhead expense because of the
     Company's operating procedures, decentralized management structure and
     management information systems. The use of regional managers and
     district managers allows the Company to minimize the levels of
     management between on-site managers and senior management.
 
  .  Expanding the Facilities--Many of the Facilities maintain levels of
     occupancy that when combined with local demand may make it economically
     feasible to expand existing storage space. Additionally, in several of
     the Company's markets, there is increasing demand for climate controlled
     space which the Company currently rents for a premium over non-climate
     controlled space. The Company constantly explores opportunities to add
     new climate controlled space or convert existing space to climate
     controlled space.
 
 External Growth Strategies
 
  The Company's external growth strategy focuses on (i) selectively acquiring
additional self-storage facilities, (ii) converting other real estate
properties into self-storage facilities and (iii) developing new facilities.
 
                                      S-5
<PAGE>
 
The Company's management consists of experienced acquisition, development,
operations and finance personnel who, when evaluating potential opportunities
for acquisition, development and conversion, analyze employment, population
and income trends, proximity to major transportation arteries, retail centers
and commercial services, visibility and other market data.
 
  .  Acquiring Existing Facilities--The Company intends to acquire self-
     storage facilities that are (i) in the Company's geographic regions of
     operations where the Company can achieve greater market penetration and
     economies of scale or in attractive new markets and in new geographic
     regions where the Company can acquire sufficient facilities to achieve
     economies of scale, (ii) available at attractive prices or currently
     underperforming and (iii) capable of enhanced performance through the
     application of the Company's management expertise. The Company focuses
     on acquisitions of Facilities of sufficient size to provide attractive
     operating efficiencies. The Company believes attractive opportunities
     exist to acquire self-storage facilities because of the fragmented
     ownership throughout the industry and the shortage of skilled operators.
     By actively targeting underperforming facilities or facilities where the
     Company can apply its proven management techniques, the Company believes
     that it will be able to enhance its yields by maximizing cash flows at
     such properties. In addition, the Company believes it has the ability to
     attract potential sellers of self-storage properties by offering units
     ("Units") representing ownership interests in Storage Trust Properties,
     L.P. (the "Operating Partnership") in exchange for such properties, thus
     allowing the sellers to defer taxes which would otherwise be payable
     upon a profitable sale of property.
 
  .  Converting Other Real Estate into Self-Storage Facilities--The Company
     also has the ability to perform complex conversions of other real estate
     buildings into self-storage facilities, especially in metropolitan
     markets where new development or acquisitions may not be economically
     feasible. The Company believes that in certain markets the costs
     relating to conversion or redevelopment can be substantially less than
     those of acquisition or development. Additionally, the Company believes
     that conversions can simultaneously provide rapid in-fill of current
     regions of the Company's markets at attractive capitalization rates.
     Previously completed conversion projects include an automobile
     dealership in St. Louis, Missouri, a hotel in New Orleans, Louisiana,
     and a former shoe warehouse in Atlanta, Georgia.
 
  .  Developing New Facilities--The Company intends to develop self-storage
     facilities in certain of its markets where there are favorable
     demographics and where suitable acquisitions may not be available. New
     development may be done by the Company or by joint ventures in which the
     Company has an interest. This development capability will allow the
     Company the opportunity to grow when acquisition opportunities are not
     plentiful or economically attractive. In making its decision to develop
     a facility, the Company obtains information such as census data for the
     relevant market with respect to population density, income levels and
     the relative proportions of rental, commercial and residential space. In
     addition, the Company weighs the costs of acquisition, as measured by
     recent market sales or bids, versus the costs of development, including
     construction, land acquisition and site preparation. The Company intends
     to develop self-storage facilities where it believes there are strong
     barriers to entry, such as a limited number of suitable sites with the
     requisite zoning. The Company also intends to focus on development of
     facilities of sufficient size to provide attractive operating
     efficiencies.
 
 Dispositions and Exchanges
 
  Management constantly reviews the Facilities comprising the Company's
portfolio. The Company has no current intention to dispose of any of the
Facilities, but may do so in the future. Any decision to dispose of a
particular Facility is based on a variety of factors, including, but not
limited to, (i) the strategic fit with the rest of the Company's portfolio,
(ii) the potential to continue to increase cash flow and value in the
particular market, (iii) the current market value and (iv) alternate uses of
capital. The Company may dispose of Facilities for cash or other consideration
or may exchange Facilities with other entities, including other publicly-held
self-storage REITs.

                              RECENT DEVELOPMENTS
 
  During 1997, the Company has expanded its portfolio of facilities and its
operating business through the acquisition, expansion and conversion of self-
storage facilities as described below. Additionally, through property
exchanges, the Company has focused on expanding in selected markets where the
Company already has a strong presence while decreasing its presence in markets
perceived to have limited opportunity for growth.
 
ACQUISITIONS AND EXCHANGES
 
  During the period from January 1, 1997 through September 30, 1997, the
Company continued its acquisition program by adding a total of 32 Facilities
to its portfolio containing an aggregate of approximately 1.7 million net
rentable square feet for an aggregate purchase price of approximately $84.5
million. Twenty-two of these Facilities, containing approximately 1.1 million
net rentable square feet, were purchased for approximately $48.8 million.
These acquisitions were funded by borrowings on the Credit Line (as defined
below). Ten of these Facilities, containing approximately 646,000 net rentable
square feet, were acquired in two separate transactions through the exchange
of 16 Facilities, valued at approximately $23.7 million, and the payment of
approximately $12 million in cash which was funded by borrowings on the Credit
Line. These acquisitions and exchanges allowed the Company to increase its
market share in certain key markets and to create operating efficiencies in
those markets through economies of scale.
 
CLIMATE-CONTROLLED CONVERSIONS
 
  The Company has completed the conversion of regular storage space to
climate-controlled space at eight facilities during the first nine months of
1997. The aggregate amount expended on these conversions was approximately
$565,000. See "--Planned Acquisitions, Developments, Expansions and
Conversions" below for information concerning additional planned climate-
controlled conversions.
 
PLANNED ACQUISITIONS, DEVELOPMENTS, EXPANSIONS AND CONVERSIONS
 
  The Company has executed contracts with respect to three self-storage
facilities with an aggregate estimated purchase price of approximately $10.3
million. Such contracts are expected to close no later than October 31, 1997.
Additionally, the Company has executed non-binding letters of intent with
respect to four additional self-storage facilities and one development parcel
with a total expected purchase price of approximately $7.9 million. The
Company expects to enter into contracts with respect to these purchases by
October 31, 1997 and to close no later than November 30, 1997. Further, the
Company is currently negotiating a number of other acquisitions, five of
which, having an aggregate estimated purchase price of approximately $21.5
million, are expected to be under contract by October 31, 1997 and to close no
later than November 30, 1997. The Company is currently conducting due
diligence on all of the above transactions and, therefore, there can be no
assurance that the acquisition of any of these facilities will occur. The
Company intends to continue to grow through acquisitions and believes that
acquired facilities can be effectively integrated into its operations because
of management's experience in operating and acquiring self-storage facilities
and the Company's centralized operating procedures and management information
systems.
 
  In addition, the Company has executed a contract with respect to a
development site near Ft. Lauderdale, Florida. The estimated purchase price
for such site is approximately $1.1 million with estimated construction and
development costs of $3.4 million.
 
  The Company has plans to complete the expansion of five Facilities during
the twelve months following October 1, 1997 at an estimated aggregate cost of
approximately $2.2 million. The expansion of three of these Facilities has
commenced and approximately $135,000 has been expended on expanding these
Facilities through September 30, 1997. Additionally, the Company has a
contract to acquire land located in Jacksonville, Florida for the expansion of
a nearby Facility. The estimated purchase price for the land is approximately
$750,000 and the Company expects to spend an additional $1.5 million in
connection with construction and development of
 
                                      S-7
<PAGE>
 
this site. Facilities are generally expanded when levels of occupancy combined
with local demand make it economically feasible in management's judgment to
expand existing self-storage space.
 
  The Company also plans to complete climate-controlled conversions at 22
Facilities between October 1, 1997 and September 30, 1998 at an estimated
aggregate cost of approximately $1.1 million. Climate-controlled conversions
have commenced at eight of these Facilities and approximately $140,000 has
been spent on converting these Facilities through September 30, 1997. In
addition, the Company is negotiating the acquisition of a building in the
Miami, Florida area which the Company intends to convert to climate-controlled
self-storage space. The estimated purchase price for this building is
approximately $750,000 and renovation costs should approximate $750,000. In
several of the Company's markets, there is increasing demand for climate-
controlled space which the Company currently rents for a premium over non-
climate-controlled space.
 
THIRD QUARTER RESULTS
 
  Funds from Operations ("FFO") for the nine months ended September 30, 1997,
were approximately $22.4 million as compared to approximately $15.8 million
for the nine months ended September 30, 1996 which represents a 41.8%
increase. FFO for the three months ended September 30, 1997 were approximately
$7.8 million, which represents an 11.7% increase over the same period in 1996.
 
  Revenues were approximately $43.8 million for the nine months ended
September 30, 1997 and approximately $16.0 million for the three months ended
September 30, 1997, which represent increases of 43.8% and 29.8%,
respectively, over the same periods in 1996. Average rent per occupied square
foot was $7.47 and $7.69 for the nine and three months ended September 30,
1997, respectively, which represent increases of 8.3% and 9.1%, respectively,
over the same periods in 1996. Occupancy was 85% as of September 30, 1997 as
compared to 87% as of September 30, 1996. For the 106 Facilities owned by the
Company during each of the nine months ended September 30, 1997 and 1996,
revenues and net operating income increased 4.8% and 5.7%, respectively. For
the 135 Facilities owned by the Company during each of the three months ended
September 30, 1997 and 1996, revenues and net operating income increased 3.7%
and 5.0%, respectively.
 
  The Board of Trustees announced a dividend increase of 5.7% to $.46 per
Common Share for the fourth quarter of 1997. The dividend will be paid on
December 29, 1997 to shareholders of record as of December 15, 1997.
 
DEBT FINANCING
 
 Senior Notes
 
  In December 1996, the Company received commitments from various
institutional investors for the private placement of $100 million of unsecured
senior notes (the "Senior Notes"). The Company funded $75 million of the
Senior Notes on January 22, 1997 and $25 million on April 15, 1997. The Senior
Notes were issued in two tranches (i) $44 million of Series A Senior Notes
with a final maturity of seven years, an average maturity of six years and a
fixed interest rate of 7.47% (125 basis points over comparable Treasuries at
the date of pricing) and (ii) $56 million of Series B Senior Notes with a
final maturity of ten years, an average maturity of eight years and a fixed
interest rate of 7.66% (135 basis points over comparable Treasuries at the
date of pricing). The proceeds of the financing were utilized to repay
indebtedness under the Credit Line and to finance the acquisition of
additional self-storage facilities.
 
 Revolving Line of Credit
 
  The Company has an unsecured revolving line of credit with an aggregate
borrowing capacity of $100 million (the "Credit Line") that expires in January
1998. However, the Company is currently negotiating the terms of a new credit
agreement with several banks. The Company expects to have such new facility in
place in
 
                                      S-8
<PAGE>
 
January 1998, although there can be no assurance that such new facility will
be in place at such time. Amounts borrowed under the Credit Line currently
bear interest at a floating rate of LIBOR plus 137.5 basis points. On
September 30, 1997, the Company had borrowings under the Credit Line of
approximately $23.8 million at a weighted average interest rate of 7.075%.
 
 Debt-to-Total Market Capitalization
 
  As of June 30, 1997, on a pro forma as adjusted basis (as described in
"Capitalization") giving effect to the application of the proceeds of the
Offering as described in "Use of Proceeds," the Company would have had $105.5
million of outstanding Company Debt (as defined below) and the ratio of
Company Debt to Total Market Capitalization (as defined below) would be 20.5%.
This is consistent with the Company's conservative capital strategy and
current policy of limiting the amount of debt as reflected on the Company's
consolidated balance sheet, including debt of joint ventures in which the
Company owns an interest (collectively, "Company Debt"), to less than 50% of
the market value of the issued and outstanding Common Shares (including
securities exchangeable for Common Shares) plus Company Debt (collectively,
"Total Market Capitalization").
 
DISTRIBUTIONS
 
  The Board of Trustees increased the quarterly distribution rate from $.3875
to $.41 per Common Share in the fourth quarter of 1995, representing a 5.8%
increase, from $.41 to $.435 per Common Share in the fourth quarter of 1996,
representing a 6.1% increase, and from $.435 to $.46 per Common Share in the
fourth quarter of 1997, representing a 5.7% increase. The future quarterly
distribution rate of $.46, if annualized, would equal an annual distribution
rate of $1.84 per Common Share. See "Price Range of Common Shares and
Distribution History."

(1) Includes 862,684 Common Shares issuable upon the exchange of Units.
    Pursuant to the partnership agreement of the Operating Partnership, each
    Unit is exchangeable for one Common Share or cash, at the option of the
    Company. Excludes 330,000 Common Shares issuable upon exercise of the
    Underwriter's over-allotment option and excludes 1,203,500 Common Shares
    issuable upon the exercise of options granted pursuant to the Storage
    Trust Realty 1994 Share Incentive Plan, as amended.
 
                                USE OF PROCEEDS
 
  The net proceeds from the sale of Common Shares offered hereby, after
deducting estimated expenses of this Offering, are expected to be
approximately $52.0 million (approximately $59.8 million if the Underwriter's
over-allotment option is exercised in full).
 
  The Company expects to use the net proceeds of the Offering to repay
indebtedness incurred pursuant to the Company's $100 million Credit Line
(approximately $23.8 million on September 30, 1997), which indebtedness was
primarily incurred in order to acquire certain of the Facilities. The
outstanding balance on the Credit Line bears interest at a floating rate of
LIBOR plus 137.5 basis points, and the Credit Line matures on January 25,
1998. On September 30, 1997, the Company had borrowings under the Credit Line
of approximately $23.8 million at a weighted average interest rate of 7.075%.
 
  The balance of the net proceeds will be used to fund the future acquisition
activity of the Company. If the Underwriter's over-allotment option to
purchase 330,000 Common Shares is exercised in full, the Company expects to
use the additional net proceeds to fund its future acquisition activity with
any remaining amounts used for general corporate purposes, including working
capital.
 
  Pending application of the net proceeds, the Company will invest such
portion of the net proceeds in interest-bearing accounts and short-term
interest-bearing securities.

    of record as of December 15, 1997.
 
  On October 15, 1997, the last reported closing sales price of the Common
Shares on the NYSE was $24 13/16 per share. On October 1, 1997, the Company
had approximately 250 shareholders of record.
 
  The Company intends to continue to pay regular distributions to holders of
Common Shares and holders of Units. The Board of Trustees increased the
quarterly distribution rate to $.46 per Common Share from $.435 per Common
Share in the fourth quarter of 1997, representing a 5.7% increase. This
quarterly distribution rate of $.46, if annualized, would equal an annual
distribution rate of $1.84 per Common Share. The distribution for the quarter
ended June 30, 1997 represented approximately 81% of the Company's FFO for
that quarter. Although the Company intends to maintain this distribution rate,
future distributions by the Company will be at the discretion of the Board of
Trustees and will depend on the actual FFO of the Company, its financial
condition, capital requirements, the annual distribution requirements under
the REIT provisions of the Code and such other factors as the Board of
Trustees deems relevant.

                            BUSINESS AND PROPERTIES
 
GENERAL
 
  The Company owns or operates 193 Facilities in specific markets in 16 states
in the Southern, Mid-Atlantic, Midwestern and Western regions of the United
States containing an aggregate of approximately 10.1 million net rentable
square feet. The Company believes that it is one of the largest operators of
self-storage facilities in the United States.
 
  Since the IPO, the Company has grown principally by acquiring additional
self-storage facilities, as well as by improving the operating performance of
the Facilities. The Company has acquired 128 wholly owned Facilities since the
IPO and has exchanged 18 wholly owned Facilities through September 30, 1997.
The Company intends to continue to grow primarily through acquisitions and
believes that acquired facilities can be effectively integrated into its
operations because of management's experience in operating and acquiring self-
storage facilities and the Company's centralized operating procedures and
management information systems.
 
  As of September 30, 1997, the Operating Partnership managed all of the
Company's wholly-owned Facilities and the Management Company managed 11
Facilities, ten of which are owned by unrelated third parties, located in six
states, containing approximately 593,000 net rentable square feet. One of the
Facilities that is managed by the Management Company is a Facility in which
the Company has an ownership interest through a joint venture. The Company
also has an ownership interest in one other Facility through a joint venture.
 
  The following table sets forth information on the Company's portfolio of 181
wholly owned Facilities as of September 30, 1997:

 Characteristics of the Facilities
 
  The Facilities in the Company's portfolio are designed to offer affordable,
accessible storage space for personal and business use. In addition, many
Facilities offer climate-controlled units as well as outside storage pads for
vehicles and boats. Customers rent fully enclosed storage units for their
exclusive use which they may freely enter during business hours, and they can
control access to their units by furnishing their own locks. Facilities are
generally fenced, have locked gates and are lighted at night. All Facilities
currently have managers who reside in an on-site apartment, except in two
instances where the manager lives adjacent to the site.
 
  The Facilities are generally near major business and residential districts
in metropolitan areas, clearly visible from and easily accessible to major
traffic arteries and protected by computer-controlled access gates, security
fencing, lighting and the presence of resident managers. The Facilities are
typically constructed of one-story metal, masonry or tilt-up concrete walls,
with an individual roll-up door for each storage space and with removable
steel interior walls to permit reconfiguration, to protect items from damage
and to separate customers' units. Sites have wide drive aisles to accommodate
most vehicles. The Facilities are designed to be aesthetically pleasing, are
kept clean and in good repair by Company-trained managers, and are open for
service during hours and on days convenient to customers and prospective
customers.
 
  Due to the type of simple structures and durable material used for
Facilities, property maintenance is minimal compared to other types of real
estate investments. Typical capital expenditures include replacing asphalt,
roofs, gates, air conditioning equipment and elevators (as contrasted with
expense items such as repairing asphalt, repairing a door, pointing up masonry
walls, painting trim and facades, repairing a fence, maintaining landscaping,
and repairing damage caused by customer vehicles). Maintenance within a
storage unit between
 
                                     S-17
<PAGE>
 
leasing typically consists of sweeping out the unit and changing a light bulb.
Maintenance is the responsibility of the facility manager.
 
  Climate-controlled units are offered in many of the Facilities for storing
files, antiques and other temperature and humidity-sensitive items.
Approximately 384,000 net rentable square feet at 56 of the Facilities offer
climate-controlled space. The Company plans to add this feature by conversion
of existing units as demand dictates. The marginal costs of building climate-
controlled space are approximately 5% higher than non-climate-controlled space
while the marginal costs of operating and maintaining climate-controlled space
are generally minimal. Based on a recent conversion, the Company believes that
it can receive a rent premium of approximately 30% on climate-controlled space
over rent for non-climate-controlled space.
 
STORAGE REALTY MANAGEMENT CO.
 
  As of September 30, 1997, the Management Company managed 11 Facilities, ten
of which are owned by unrelated third parties. One of the Facilities that is
managed is a Facility in which the Company has an ownership interest through a
joint venture. The managed Facilities contain approximately 593,000 net
rentable square feet and are located in the following six states: Missouri
(3), Florida (2), Kansas (2), Texas (2), Georgia (1) and Virginia (1). While
the Management Company does not intend to actively expand this aspect of its
operations, management of additional facilities in the future may be
considered as a precursor to acquisition by the Operating Partnership or in
order for the Company to become familiar with an attractive new market.
Additionally, the Management Company conducts various other businesses, such
as the sale of locks, boxes and packaging supplies, the processing of customer
property insurance and the rental of trucks, at various Facilities.
 
  BHC owns 95% of the voting common stock of the Management Company, which is
generally entitled to dividends equal to 4.75% of all distributions. The
remaining 5% of the voting common stock, entitled to .25% of all
distributions, is owned by the Operating Partnership. The Operating
Partnership owns 100% of the nonvoting preferred stock of the Management
Company. The nonvoting preferred stock is entitled to dividends equal to 95%
of all distributions of the Management Company. The charter of the Management
Company requires the quarterly distribution as dividends of its net cash flow,
subject to the discretion of the board of directors that there are funds
legally available therefor. Such provision may not be changed without the
consent of the holder of the preferred stock. Accordingly, the Operating
Partnership expects to receive substantially all of the available net cash
flow from the Management Company through ownership of the preferred stock and
thereby will receive substantially all of the economic benefit of the
operations carried on by the Management Company.
 
THE INDUSTRY
 
  The self-storage industry is an integral part of the commercial and
residential real estate markets, serving the storage needs of businesses and
consumers. Initially developed in the early 1960s in the southwestern United
States, self-storage facilities were built in response to the growing need for
low-cost accessible storage. A number of factors have accelerated the demand
for storage facilities including, among others, a more mobile society, with
individuals moving to new homes and new cities needing short-term storage for
their belongings, the increasing cost of residential housing (resulting in
smaller houses), the increased popularity of apartments and condominiums, more
individuals with growing discretionary income (resulting in the accumulation
of more possessions and the purchase of items such as boats and recreational
vehicles which cannot be stored at residences), the growing number of small
businesses and the escalating cost of other storage alternatives. In addition
to traditional use by consumers, many retail stores and other businesses use
self-storage facilities to store goods received from warehouses or, in some
instances, directly from manufacturers, through just-in-time delivery systems.
Self-storage facilities serve as additional storage capacity for households
acquiring goods or businesses building inventory or producing storable items,
such as new products or records.
 
  In addition to providing affordable, accessible storage space for personal
and business use, many facilities offer climate controlled units as well as
outside storage pads for vehicles and boats. With the advent of resident
managers, storing goods became a far more convenient process for customers
(i.e., tenants renting self-storage
 
                                     S-18
<PAGE>
 
space), resulting in increased customer awareness and appreciation. Rental
units are usually secured by customer locks and only the customer has the key,
thus ensuring controlled access. Facilities are generally fenced, have locked
gates and are lighted at night. Computerized access gates for self-storage
have made the overall storage process more convenient for the customer.
 
  The successful development of self-storage facilities is becoming
increasingly sophisticated. Specialized skills in areas such as site
selection, design and unit mix are critical to the development of successful
new self-storage projects on a cost efficient basis. Furthermore, new
development in self-storage has become more difficult due to the lack of
available capital, pressure from zoning boards and municipalities, and
increases in building costs as new facilities are required to meet rigorous
landscaping and other aesthetically oriented standards.
 
REGULATION
 
 Environmental Matters
 
  The Company is subject to federal, state, and local environmental laws,
ordinances and regulations that apply to the development of real property,
including construction activities, the ownership of real property, and the
operation of self-storage facilities.
 
  In developing properties and constructing facilities, the Company utilizes
environmental consultants to determine whether there are any flood plains or
wetlands or environmentally sensitive areas that are part of the property to
be developed. If flood plains are identified, development and construction are
planned so that flood plain areas are preserved or alternative flood plain
capacity is created in conformance with federal and local flood plain
management requirements.
 
  Storm water discharge from a construction site is evaluated in connection
with the requirements for storm water permits under the Clean Water Act. This
is an evolving program in most states. It is anticipated that general storm
water permits will be applicable to the Company's activities, and individual
permits will not be required for existing or new development.
 
  Under various federal, state and local laws, ordinances and regulations, an
owner or operator of real property may become liable for the costs of removal
or remediation of certain hazardous or toxic substances on, under or in such
property. Such laws, ordinances and regulations often impose liability without
regard to whether the owner or operator knew of, or was responsible for, the
presence of such hazardous or toxic substances. The presence of hazardous or
toxic substances, or the failure to properly remediate such substances, when
released, may adversely affect the owner's ability to sell or lease such real
estate or to borrow using such real estate as collateral, and may cause the
property owner to incur substantial remediation costs. In addition to claims
for cleanup costs, the presence of hazardous substances on a property could
result in a claim by a private party for personal injury or a claim by an
adjacent property for property damage.
 
  The Company has not been notified by any governmental authority of any
material noncompliance, claim, or liability in connection with any of the
Facilities. The Company has not been notified of a claim for personal injury
or property damage by a private party in connection with any of the Facilities
in connection with environmental conditions.
 
  A Phase I environmental assessment for each of the Facilities has been
prepared by an independent environmental consultant. The purpose of each such
report was to identify, to the extent reasonably possible and based on
reasonably available information, whether the environmental quality of the
Facility had been affected by hazardous or toxic substances, including
petroleum products and asbestos.
 
  The scope of the Phase I environmental assessment for each such Facility
generally included: (i) a review of reasonably available maps, aerial
photographs and other public information to analyze the past and present uses
of the site; (ii) limited inquiries of federal, state and local agencies
having jurisdiction over certain
 
                                     S-19
<PAGE>
 
environmental matters; and (iii) an on-site assessment of the Facility to
inspect for evidence of past or present on-site waste disposal, visible
surface contamination, above-surface and subsurface storage tanks, drums,
barrels and other storage containers, current waste streams and management
practices, ACMs, and PCB transformers. In addition, as part of the Phase I
environmental assessment, abutting properties and nearby sources of potential
contamination were identified and evaluated for potential impact to the
Facility, to the extent reasonably possible.
 
  The environmental assessments, and in certain circumstances further
investigation, have not revealed, nor is the Company aware of, any
environmental condition with respect to the Facilities that is expected to
have a material adverse effect on the Company's financial condition or results
of operations. No assurances can be given, however, that (a) the environmental
assessments and further investigation which have been conducted with respect
to the Facilities or which will be conducted with respect to the facilities
that may be acquired or developed in the future, have revealed, or will
reveal, all potential environmental liabilities, (b) any prior owner or
operator of the real property on which the Facilities are located did not
create any material environmental condition not known to the Company, or (c)
an environmental condition does not otherwise exist as to any one or more of
the Facilities, which liabilities or conditions could have a material adverse
effect upon the financial condition or results of operations of the Company.
 
 Americans with Disability Act
 
  Under the Americans with Disability Act ("ADA"), all public accommodations
are required to meet certain federal requirements related to physical access
and use by disabled persons. While the Company believes that the Facilities
comply in all material respects with these physical requirements (or would be
eligible for applicable exemptions from material requirements because of
adaptive assistance provided), a determination that the Company is not in
compliance with the ADA could result in the imposition of fines, injunctive
relief, damages or attorney's fees. If the Company were required to make
modifications to comply with the ADA, the Company's ability to make expected
distributions to its shareholders could be adversely affected; however,
management believes that such effect would be minimal.
 
 Local Regulations
 
  As with all real property, self-storage facilities must conform to local
zoning ordinances. The Facilities' operations have not been subjected to any
material zoning complaints. Typically, self-storage facilities are not a
permitted use within the commercial and retail areas desired by the Company
for the development of a new facility. Therefore, the Company must generally
obtain a variance to undertake the development of a new facility. The zoning
classifications for self-storage have been narrowed repeatedly so that new
self-storage development within major metropolitan areas is becoming
increasingly difficult. The restrictive zoning regulations may keep the
industry restricted to all but those who have the expertise to show the
benefits of self-storage to a community and have the credentials necessary to
persuade zoning boards to rezone or grant variances.

(1) Represents the Company's net income (loss) after minority interest of the
    holders of Units and the other shareholder in the Management Company.
 
(2) FFO is defined by the National Association of Real Estate Investment
    Trusts ("NAREIT") as net income (loss) before minority interest (computed
    in accordance with generally accepted accounting principles ("GAAP")),
    excluding gains or losses from debt restructuring and sales of property,
    provision for losses and real estate related depreciation and amortization
    (excluding amortization of financing costs). Effective in 1996, the
    definition of FFO was modified by NAREIT to exclude the add-back of the
    amortization of deferred financing fees and depreciation of non real
    estate assets. The Company has adopted this new definition. Amounts for
    prior years have been revised to conform to the new definition. The
    Company believes that FFO is helpful to investors as a measure of the
    performance of an equity REIT because, along with cash flows from
    operating activities, investing activities and financing activities, it
    provides investors with an understanding of the ability of the Company to
    incur and service debt and to make capital expenditures. FFO is not to be
    considered as an alternative to net income or any other GAAP measurement
    as a measure of operating performance and is not necessarily indicative of
    cash available to fund all cash needs. The FFO measure presented by the
    Company may not be comparable to similarly titled measures of other REITs.
 
(3) EBITDA means operating income before minority interest, mortgage and other
    interest expense, income taxes, depreciation and amortization. EBITDA does
    not represent cash generated from operating activities in accordance with
    GAAP, is not to be considered as an alternative to net income or any other
    GAAP measurement as a measure of operating performance, and is not
    necessarily indicative of cash available to fund all cash needs. The
    Company has included EBITDA herein because, along with cash flows from
    operating activities, financing activities and investing activities, it
    provides operating information relevant to the Company's ability to incur
    and service debt and to make capital expenditures.
 
(4) Determined by dividing net rentable square feet occupied at the end of
    such period by total net rentable square feet, excluding Facilities
    acquired or opened near the end of the period.
 
(5) Revenues per square foot are calculated on a weighted average annual
    basis. For the six-month periods, the average revenues per square foot are
    on an annualized basis.

FUNDS FROM OPERATIONS
 
  The Company believes that FFO is helpful to investors as a measure of the
performance of an equity REIT because, along with cash flows from operating
activities, financing activities and investing activities, it provides
investors with an understanding of the ability of the Company to incur and
service debt and to make capital expenditures. FFO is defined by NAREIT as
income (loss) before minority interest (computed in accordance with GAAP),
excluding gains or losses from debt restructuring and sales of property,
provision for losses, and real estate related depreciation and amortization
(excluding amortization of financing costs). FFO is not to be considered as an
alternative to net income or any other GAAP measurement as a measure of
operating performance and is not necessarily indicative of cash available to
fund all cash needs. The FFO measure presented by the Company may not be
comparable to similarly titled measures of other REITs. Effective in 1996, the
definition of FFO was modified by NAREIT to exclude the add-back of the
amortization of deferred financing fees and depreciation of non real estate
assets. The Company has adopted this new definition. Amounts for prior years
have been revised to conform to the new definition.
 
FFO is determined as follows (amounts in thousands except for share data):

  FFO increased $2,795,000 (60.9%) in the second quarter of 1997 over 1996 due
to the acquisition of Facilities in 1997 and 1996 and the increased results
from those Facilities owned for all of the three months ended June 30, 1997
and 1996. Net operating income, defined as revenues less property operating
expenses and real estate taxes, increased on a same store basis by $224,000
(3.7%). These increases were partially offset by increases in general and
administrative expenses and interest expense.
 
  FFO increased $5,718,000 (64.9%) in the first six months of 1997 over 1996
due to the acquisition of Facilities in 1997 and 1996 and the increased
results from those Facilities owned for all of the six months ended June 30,
1997 and 1996. Net operating income increased on a same store basis by
$633,000 (5.8%). These increases were partially offset by increases in general
and administrative expenses and interest expense.
 
  FFO decreased $184,000 (1.3%) for the pro forma six months ended June 30,
1997 as compared to actual results for this time period due primarily to the
fact that (a) the operations of five Facilities acquired during 1997 were in
their initial lease-up period and (b) one Facility acquired during 1997 was
undergoing a significant expansion that opened in June 1996.

LIQUIDITY AND CAPITAL RESOURCES
 
  Mortgages and Notes Payable
 
  The Company had outstanding borrowings of approximately $123.8 million as of
September 30, 1997. This indebtedness consists of (a) $100 million of Senior
Notes and (b) approximately $23.8 million outstanding under the Credit Line.
The Credit Line is used primarily to fund the acquisition, development or
conversion of additional facilities. The Credit Line expires in January 1998,
and bears interest at a floating rate of LIBOR plus 1.375% (7.075% at
September 30, 1997). However, the Company is currently negotiating the terms
of a new credit agreement with several banks which is expected to be effective
in January 1998.
 
  In December 1996, the Company received commitments from various
institutional investors for the private placement of $100 million of Senior
Notes. The Company funded $75 million of the Senior Notes on January 22, 1997
and the remaining $25 million was funded on April 15, 1997. The Senior Notes
were issued in two tranches (i) $44 million of Series A Senior Notes with a
final maturity of seven years, an average maturity of six years and a fixed
interest rate of 7.47% per annum (125 basis points over comparable Treasuries
at the date of pricing) and (ii) $56 million of Series B Senior Notes with a
final maturity of ten years, an average maturity of eight years and a fixed
interest rate of 7.66% per annum (135 basis points over corresponding
Treasuries at the date of pricing). The proceeds of the financing were
utilized to repay indebtedness under the Credit Line and to finance the
acquisition of additional self-storage facilities.
 
  At September 30, 1997, the Company has joint and several liability with
respect to approximately $3.9 million of indebtedness of a joint venture in
New Orleans, Louisiana in which it has a 15% interest. In 1996, the Company
acquired a 25% interest in a joint venture that is operating a self-storage
facility in Kansas City, Missouri that was constructed during 1997. The
Company has guaranteed 25% of the joint venture's construction loan, which is
for a total of approximately $2.1 million. The balance outstanding under this
construction loan as of September 30, 1997 was approximately $1.8 million.
 
  Liquidity
 
  The expansion of existing Facilities, the acquisition, conversion and
development of additional self-storage facilities and the repayment of
indebtedness, including the Senior Notes and any amounts outstanding on the
Credit Line, represent the Company's principal liquidity requirements.
 
  The Company expects to meet its short-term liquidity requirements from (i)
net cash provided by operating activities and (ii) borrowings under the Credit
Line. The Company expects to meet is long-term liquidity requirements by (i)
borrowings under the Credit Line, (ii) the issuance of new debt and (iii) the
sale of Common Shares.
 
  The Company believes that its future net cash flow will be adequate to meet
operating requirements and provide for payment of distributions by the Company
in accordance with tax requirements relating to a REIT in the short-term and
in the long-term. In order to maintain its status as a REIT, the Company will
be required to make distributions to its shareholders of at least 95% of its
taxable income, which is expected to consist primarily of its share of the
income of the Operating Partnership. Differences in timing between the
recognition of taxable income and receipt of cash which would be available for
distribution could require the Company to borrow to meet the 95% distribution
requirement, although the Company does not currently anticipate the need to
borrow as a result of any such differences in timing.
 
CAPITAL EXPENDITURES
 
  During the three months ended March 31, 1997, the Company spent $187,000 for
expansions of existing Facilities and climate-controlled conversions and
$446,000 on other capital expenditures. During the three months ended June 30,
1997, the Company spent $131,000 for expansions of existing Facilities and
climate-controlled conversions and $832,000 on other capital expenditures. For
the twelve months ending June 30, 1998, the Company expects to spend
$7,800,000 for expansions and climate-controlled conversions at existing
Facilities. For the remaining six months of 1997, the Company expects to spend
$1,350,000 on other capital expenditures. The Company believes that it can
fund any necessary capital expenditures through its operations or from the
Credit Line.

                              RECENT LEGISLATION
 
  For taxable years beginning after August 5, 1997, the Taxpayer Relief Act of
1997 (the "1997 Act") permits a REIT, with respect to undistributed net
capital gains it received during the taxable year, to designate in a notice
mailed to shareholders within 60 days of the end of the taxable year (or in a
notice mailed with its annual report for the taxable year) such amount of such
gains which its shareholders are to include in their taxable income as long-
term capital gains. Thus, if the Company made this designation, the
shareholders of the Company would include in their income as long-term capital
gains their proportionate share of the undistributed net capital gains as
designated by the Company, and the Company would have to pay the tax on such
gains within 30 days after the close of its taxable year. Each shareholder of
the Company would be deemed to have paid such shareholder's share of the tax
paid by the Company on such gains, which tax would be credited or refunded to
the shareholder. A shareholder would increase his tax basis in his Company
stock by the difference between the amount of gain to the holder resulting
from the designation less the holder's credit or refund for the tax paid by
the Company. See the accompanying Prospectus under "Federal Income Tax
Considerations-- Taxation of the Company--General" and under "Taxation of the
Company--Annual Distribution Requirements."
 
  Under the 1997 Act, for taxable years beginning after August 5, 1997, if the
Company complies with the Treasury regulations for ascertaining its actual
ownership and did not know, or exercising reasonable diligence would not have
reason to know, that more than 50% in value of its outstanding shares of stock
were held, actually or constructively, by five or fewer individuals, then the
Company will be treated as meeting such requirement. See the accompanying
Prospectus under "Federal Income Tax Considerations--Taxation of the Company--
Share Ownership Tests."
 
  For taxable years beginning after August 5, 1997, a REIT is permitted to
render a de minimis amount of impermissible services to tenants, or in
connection with the management of property, and still treat amounts received
with respect to that property as rent from real property. The amount received
or accrued by the REIT during a taxable year for impermissible services with
respect to a property may not exceed one percent of all amounts received or
accrued by the REIT directly or indirectly from the property during the
taxable year. The amount received for any service (or management operation)
for this purpose shall be deemed to be not less than 150% of the direct cost
of the REIT in furnishing or rendering the service (or providing the
management or operation). See the accompanying Prospectus under "Federal
Income Tax Considerations--Taxation of the Company--The 75% Test."
 
  The 1997 Act repeals the 30% gross income test for REITs for taxable years
beginning after August 5, 1997. See the accompanying Prospectus under "Federal
Income Tax Considerations--Taxation of the Company--The 30% Test."
 
  For taxable years beginning after August 5, 1997, the 1997 Act (i) expands
the class of non-cash income that is excluded from the distribution
requirement to include income from the cancellation of indebtedness and (ii)
extends the treatment of original issue discount ("OID") (over cash and the
fair market value of property received on the instrument) as such non-cash
income to OID instruments generally and for REITs, like the Company, that use
an accrual method of accounting. See the accompanying Prospectus under
"Federal Income Tax Considerations--Taxation of the Company--Annual
Distribution Requirements."
 
  The 1997 Act made certain changes to the Code with respect to taxation of
long-term capital gains earned by taxpayers other than a corporation. In
general, for sales made after May 6, 1997, the maximum tax rate for individual
taxpayers on net long-term capital gains (i.e., the excess of net long-term
capital gain over net short-term capital loss) is lowered to 20% for most
assets. This 20% rate applies to sales on or after July 29, 1997 only if the
asset was held for more than 18 months at the time of disposition. Capital
gains on the disposition of assets on or after July 29, 1997 held for more
than one year and up to 18 months at the time of disposition will be taxed as
"mid-term gain" at a maximum rate of 28%. Also, so called "unrecaptured
section 1250 gain" is subject to a maximum federal income tax rate of 25%.
"Unrecaptured section 1250 gain" generally includes the long-term capital gain
realized on (i) the sale after May 6, 1997 of a real property asset described
in Section 1250 of the Code or (ii) the sale after July 28, 1997 of a real
property asset described in Section 1250 of the
 
                                     S-28
<PAGE>
 
Code which the taxpayer has held for more than 18 months, but in each case not
in excess of the amount of depreciation (less the gain, if any, treated as
ordinary income under Code Section 1250) taken on such asset. A rate of 18%
instead of 20% will apply after December 31, 2000 for assets held for more
than 5 years. However, the 18% rate applies only to assets acquired after
December 31, 2000 unless the taxpayer elects to treat an asset held prior to
such date as sold for fair market value on January 1, 2001. In the case of
individuals whose ordinary income is taxed at a 15% rate, the 20% rate is
reduced to 10% and the 10% rate for assets held for more than 5 years is
reduced to 8%.
 
  Certain aspects of the new legislation on capital gains are currently
unclear, including how the reduced rates will apply to gains earned by REITs
such as the Company. Until the Internal Revenue Service (the "Service") issues
some guidance, it is unclear whether or how the 20% or 10% rates will apply to
distributions of long-term capital gains by the Company. The 1997 Act gives
the Service authority to apply the 1997 Act's new rules on taxation of capital
gains to sales by pass-thru entities, including REITs. It is possible that the
Service could provide in such regulations that REIT capital gain dividends
must be determined by looking through to the assets sold by the REIT and
treated by REIT stockholders as "long-term capital gain", "mid-term gain" and
"unrecaptured section 1250 gain" to the extent of such respective gain
realized by the REIT. No regulations have yet been issued. Such regulations,
if and when issued, may have a retroactive affect. See the accompanying
Prospectus under "Federal Income Tax Considerations--Taxation of
Shareholders--Taxation of Taxable Domestic Shareholders."
 
  Shareholders of the Company should consult their tax advisor with regard to
(i) the application of the changes made by the 1997 Act with respect to
taxation of capital gains and capital gain dividends and (ii) to state, local
and foreign taxes on capital gains.
 
  New Treasury Regulations recently have been adopted that revise in certain
respects the rules applicable to Non-U.S. Shareholders (the "New
Regulations"). The New Regulations are generally effective with respect to
payments made after December 31, 1998.
 
  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 (see the discussion in the accompanying Prospectus under
"Certain United States Tax Considerations for Non-U.S. Shareholders--
Distributions from the Company--Ordinary Dividends"), 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 Internal Revenue Service
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 Internal Revenue Service. 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 county 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 Service.
 
  The New Regulations also make certain changes in the new information
reporting and backup withholding rules for payments made after December 31,
1998. Shareholders should consult their tax advisors with respect to such
changes.

                                  UNDERWRITING
 
  Subject to the terms and conditions set forth in an underwriting agreement
(the "Underwriting Agreement"), the Company has agreed to sell to BancAmerica
Robertson Stephens and the Underwriter has agreed to purchase from the Company
2,200,000 Common Shares.
 
  Under the terms and conditions of the Underwriting Agreement, the Underwriter
is committed to take and pay for all of the Common Shares included in the
Offering, if any are taken.
 
  The Underwriter proposes to offer the Common Shares offered hereby from time
to time for sale in one or more transactions on the NYSE, in the over-the-
counter market or otherwise, at market prices prevailing at the time of sale,
at prices related to prevailing market prices, or at negotiated prices, subject
to prior sale when, as and if delivered to and accepted by the Underwriter. In
connection with the sale of the Common Shares included in the Offering, the
Underwriter may be deemed to have received compensation from the Company in the
form of underwriting discounts. The Underwriter may effect such transactions by
selling Common Shares to or through dealers, and such dealers may receive
compensation in the form of discounts, concessions or commissions from the
Underwriter and/or the purchasers of such Common Shares for whom they may act
as agents or to whom they may sell as principal.
 
  The Company has granted the Underwriter an option, exercisable within 30 days
of the date of this Prospectus Supplement, to purchase up to 330,000 additional
Common Shares from the Company at the same price per share as the initial
2,200,000 Common Shares to be purchased by the Underwriter. The Underwriter may
exercise such option only to cover over-allotments, if any, incurred in
connection with the Offering.
 
  In the Underwriting Agreement, the Company has agreed to indemnify the
Underwriter against certain liabilities, including liabilities under the
Securities Act of 1933, as amended (the "Securities Act"), or to contribute to
payments the Underwriter may be required to make in respect thereof.
 
  Subject to certain exceptions, the Company, the Operating Partnership and
certain of the Company's executive officers and directors have agreed that, for
a period of 90 days from the date of this Prospectus Supplement, they will not,
without the prior written consent of the Underwriter, directly or indirectly,
offer, sell, contract to sell or otherwise dispose of any Common Shares or any
security convertible into or exercisable or exchangeable for Common Shares.
 
  In connection with the Offering, the rules of the Securities and Exchange
Commission (the "Commission") permit the Underwriter to engage in certain
transactions that stabilize the price of the Common Shares. Such transactions
consist of bids or purchases for the purpose of pegging, fixing or maintaining
the price of the Common Shares.
 
  If the Underwriter creates a short position in the Common Shares in
connection with the Offering, i.e., if it sells more Common Shares than are set
forth on the cover page of this Prospectus Supplement, the Underwriter may
reduce that short position by purchasing Common Shares in the open market. The
Underwriter may also elect to reduce any short position by exercising all or
part of the over-allotment option described above. In general, purchases of a
security for the purpose of stabilization or to reduce a short position could
cause the price of the security to be higher than it might be in the absence of
such purchases.
 
  Neither the Company nor the Underwriter makes any representation or
prediction as to the direction or magnitude of any effect that the transactions
described above may have on the price of the Common Shares. In addition,
neither the Company nor the Underwriter makes any representation that the
Underwriter will engage in such transactions or that such transactions, once
consummated, will not be discontinued without notice.
 
  The Common Shares are traded on The New York Stock Exchange under the symbol
"SEA."

                                  THE COMPANY
 
  The Company and its affiliates constitute a self-administered and self-
managed real estate investment trust (a "REIT") which was organized in
November 1994 to continue and expand the self-storage facility business
conducted by Burnam Holding Companies Co. and certain of its affiliates
(collectively, "BHC" or the "Predecessor Company") since 1974. The Company and
its affiliates own, manage, lease, acquire and develop self-storage
facilities. The Company owns and operates self-storage facilities
("Facilities") in the Southern, Mid-Atlantic, Midwestern and Western regions
of the United States. The Company offers a broad range of features and
amenities to its customers, including uniformed customer service-oriented
facility managers, door alarms, lighting systems, video cameras, twenty-four
hour computer-controlled access, climate-controlled storage spaces, attractive
buildings and wide drive aisles.
 
  The business of the Company is operated through Storage Trust Properties,
L.P. (the "Operating Partnership") and Storage Realty Management Co. (the
"Subsidiary Company"). Substantially all of the Company's assets and interest
in self-storage facilities are held by, and all of its operations are
conducted through, the Operating Partnership. The Company is the sole general
partner of, and thereby controls the operations of, the Operating Partnership,
holding an approximately 93.8% (as of October 31, 1996) ownership interest
therein. The remaining ownership interests in the Operating Partnership (the
"Units") are primarily held by certain owners of the Predecessor Company,
including BHC (collectively, "Original Investors"), and certain former owners
of assets acquired by the Operating Partnership subsequent to the Company's
initial public offering of Common Shares. The Subsidiary Company manages
Facilities owned by unrelated third parties and conducts various other
businesses, such as the sale of locks and the processing of customer property
insurance, at various Facilities. Through its ownership of the preferred stock
of the Subsidiary Company, the Operating Partnership enjoys substantially all
of the economic benefit of the businesses carried on by the Subsidiary
Company.
 
  The Company was formed as a Maryland real estate investment trust on July
12, 1994. The Company's executive offices are located at 2407 Rangeline
Street, Columbia, Missouri 65202 and its telephone number is (573) 499-4799.
 
                                USE OF PROCEEDS
 
  Unless otherwise described in the Prospectus Supplement which accompanies
this Prospectus, the Company intends to use the net proceeds from the sale of
the Offered Securities for the acquisition and development of self-storage
facilities as suitable opportunities arise, improvement of the Facilities
owned by the Company, repayment of certain then-outstanding secured or
unsecured indebtedness and for general corporate purposes.
 
                         DESCRIPTION OF COMMON SHARES
 
GENERAL
 
  The Second Amended and Restated Declaration of Trust of the Company (the
"Declaration of Trust") provides that the Company may issue up to 150,000,000
shares of beneficial interest, $.01 par value per share, consisting of common
shares and such other types or classes of securities of the Company as the
Trustees may create and authorize from time to time and designate as
representing a beneficial interest in the Company. No holder of any class of
shares of beneficial interest of the Company has any preemptive right to
subscribe to any securities of the Company except as may be granted by the
Board of Trustees in authorizing the issuance or reclassification of a class
of shares of beneficial interest. For a description of certain provisions that
could have the effect of delaying, deferring or preventing a change in
control, see "Certain Provisions of Maryland Law and of the Company's
Declaration of Trust and Bylaws."
 
 
                                       3
<PAGE>
 
  The following description sets forth certain general terms and provisions of
the Common Shares to which any Prospectus Supplement may relate, including a
Prospectus Supplement which provides for Common Shares issuable pursuant to
subscription offerings or rights offerings. The statements below describing
the Common Shares are in all respects subject to and qualified in their
entirety by reference to the applicable provisions of the Declaration of Trust
and the Amended and Restated Bylaws of the Company (the "Bylaws"). For further
information regarding the Common Shares, see "Certain Provisions of Maryland
Law and of the Company's Declaration of Trust and Bylaws."
 
  All the Common Shares covered by the Registration Statement of which this
Prospectus is a part will be, when issued, duly authorized, fully paid and,
except as described under "Shareholder Liability" below, non-assessable.
Subject to the provisions of the Declaration of Trust regarding Excess Shares
(as defined therein), each outstanding Common Share entitles the holder
thereof to one vote on all matters voted on by shareholders, including the
election of Trustees. Holders of Common Shares do not have the right to
cumulate their votes in the election of Trustees, which means that the holders
of a majority of the outstanding Common Shares can elect all of the Trustees
then standing for election. Distributions may be paid to the holders of Common
Shares if and when declared by the Board of Trustees of the Company out of
funds legally available therefor, subject to the provisions of the Declaration
of Trust regarding Excess Shares. The Company currently pays regular quarterly
dividends. Holders of Common Shares have no conversion, redemption, preemptive
or exchange rights to subscribe to any securities of the Company. If the
Company is liquidated, each outstanding Common Share will be entitled to
participate pro rata in the assets remaining after payment of, or adequate
provision for, all known debts and liabilities of the Company and the rights
of holders of any preferred shares of beneficial interest of the Company. The
rights of holders of Common Shares are subject to the rights and preferences
established by the Board of Trustees for any preferred shares of beneficial
interest which may subsequently be issued by the Company.
 
RESTRICTIONS ON TRANSFER
 
  Ownership Limits. The Declaration of Trust contains certain restrictions on
the number of Common Shares that individual shareholders may own. For the
Company to qualify as a REIT under the Code, no more than 50% in value of its
shares of beneficial interest (after taking into account options to acquire
shares of beneficial interest and shares of beneficial interest issuable on
conversion of convertible securities) may be owned, directly or indirectly, by
five or fewer individuals (as defined in the Code to include certain entities
and constructive ownership among specified family members) during the last
half of a taxable year (other than the first taxable year) or during a
proportionate part of a short taxable year. The Common Shares must also be
beneficially owned (other than during the first taxable year) by 100 or more
persons during at least 335 days of a taxable year or during a proportionate
part of a shorter taxable year. Because the Company expects to qualify as a
REIT, the Declaration of Trust contains restrictions on the acquisition of
Common Shares intended to ensure compliance with these requirements.
 
  Subject to certain exceptions specified in the Declaration of Trust, no
holder may own, or be deemed to own by virtue of the attribution provisions of
the Code, more than 6% (the "Ownership Limit") of the number or value of the
issued and outstanding shares of beneficial interest of the Company. The
Company's Board of Trustees, upon receipt of a ruling from the Internal
Revenue Service (the "Service") or an opinion of counsel or other evidence
satisfactory to the Board of Trustees and upon such other conditions as the
Board of Trustees may direct, may also exempt a proposed transferee from the
Ownership Limit. As a condition of such exemption, the proposed transferee
must give written notice to the Company of the proposed transfer no later than
the fifteenth day prior to any transfer which, if consummated, would result in
the intended transferee owning shares in excess of the Ownership Limit. The
Board of Trustees of the Company may require such opinions of counsel,
affidavits, undertakings or agreements as it may deem necessary or advisable
in order to determine or ensure the Company's status as a REIT. Any transfer
of shares that would (i) create a direct or indirect ownership of shares in
excess of the Ownership Limit, (ii) result in the shares being beneficially
owned by fewer than 100 persons (determined without reference to any rules of
attribution) as provided in Section 856(a) of the Code, or (iii) result
 
                                       4
<PAGE>
 
in the Company being "closely held" within the meaning of Section 856(h) of
the Code, shall be null and void ab initio, and the intended transferee will
acquire no rights to the shares. The foregoing restrictions on transferability
and ownership will not apply if the Board of Trustees determines, which
determination must be approved by the shareholders, that it is no longer in
the best interests of the Company to attempt to qualify, or to continue to
qualify, as a REIT.
 
  The Company's Board of Trustees has, by resolution, excluded from the
foregoing ownership restriction BHC and Gordon Burnam, Bonnie Burnam, Kimberly
Flower, P. Crismon Burnam, Michael G. Burnam, Timothy B. Burnam, any member of
their respective immediate families and any of their respective affiliates,
heirs, devisees, legal representatives, successors or beneficiaries (the
"Burnam Family"), who collectively may own up to 25% of the outstanding shares
of beneficial interest of the Company as a group. Additionally, the
Declaration of Trust excludes from the foregoing ownership restriction certain
Original Investors (and their transferees) who would exceed the Ownership
Limit as a result of the exchange of Units for Common Shares. In no event will
such persons be entitled to acquire additional shares of beneficial interest
of the Company such that the five largest beneficial owners of shares of
beneficial interest of the Company hold more than 50% of the total outstanding
shares.
 
  Any shares the purported transfer of which would result in a person owning
shares of beneficial interest in excess of the Ownership Limit or cause the
Company to become "closely held" under Section 856(h) of the Code that is not
otherwise permitted as provided above will constitute excess shares ("Excess
Shares"), which will be transferred pursuant to the Declaration of Trust to a
party not affiliated with the Company designated by the Company as the trustee
of a trust for the exclusive benefit of an organization or organizations
described in Sections 170(b)(1)(A) and 170(c) of the Code and identified by
the Board of Trustees as the beneficiary or beneficiaries of the trust (the
"Charitable Beneficiary"), until such time as the Excess Shares are
transferred to a person whose ownership will not violate the restrictions on
ownership. While these Excess Shares are held in trust, they will not be
entitled to share in any distributions which will be paid to the trust for the
benefit of the Charitable Beneficiary and may only be voted by the trustee for
the benefit of the Charitable Beneficiary. Subject to the Ownership Limit, the
Excess Shares shall be transferred by the trustee at the direction of the
Company to any person (if the Excess Shares would not be Excess Shares in the
hands of such person). The purported transferee will receive the lesser of (i)
the price paid by the purported transferee for the Excess Shares (or, if no
consideration was paid, fair market value on the day of the event causing the
Excess Shares to be held in trust) and (ii) the price received from the sale
or other disposition of the Excess Shares held in trust. Any proceeds in
excess of the amount payable to the purported transferee will be paid to the
Charitable Beneficiary. In addition, such Excess Shares held in trust are
subject to purchase by the Company for a 90 day period at a purchase price
equal to the lesser of (i) the price paid for the Excess Shares by the
purported transferee (or, if no consideration was paid, fair market value at
the time of the event causing the shares to be held in trust) and (ii) the
fair market value of the Excess Shares on the date the Company elects to
purchase. Fair market value, for these purposes, means the last reported sales
price reported on the NYSE on the trading day immediately preceding the
relevant date, or if not then traded on the NYSE, the last reported sales
price on the trading day immediately preceding the relevant date as reported
on any exchange or quotation system over or through which the relevant class
of shares of beneficial interest may be traded, or if not then traded over or
through any exchange or quotation system, then the market price on the
relevant date as determined in good faith by the Board of Trustees of the
Company.
 
  From and after the purported transfer to the purported transferee of the
Excess Shares, the purported transferee shall cease to be entitled to
distributions, voting rights and other benefits with respect to the Excess
Shares except the right to payment on the transfer of the Excess Shares as
described above. Any distribution paid to a purported transferee on Excess
Shares prior to the discovery by the Company that such Excess Shares have been
transferred in violation of the provisions of the Declaration of Trust shall
be repaid, upon demand, to the Company, which shall pay any such amounts to
the trust for the benefit of the Charitable Beneficiary. If the foregoing
transfer restrictions are determined to be void, invalid or unenforceable by
any court of competent jurisdiction, then the purported transferee of any
Excess Shares may be deemed, at the option of the Company, to have acted as an
agent on behalf of the Company in acquiring such Excess Shares and to hold
such Excess Shares on behalf of the Company.
 
  All certificates representing shares of beneficial interest will bear a
legend referring to the restrictions described above.
 
                                       5
<PAGE>
 
  All persons who own, directly or by virtue of the attribution provisions of
the Code, more than 5% (or such other percentage between 1/2 of 1% and 5%, as
provided in the rules and regulations promulgated under the Code) of the
number or value of the outstanding shares of beneficial interest of the
Company must give a written notice containing certain information to the
Company by January 31 of each year. In addition, each shareholder shall upon
demand be required to disclose to the Company in writing such information with
respect to the direct, indirect and constructive ownership of shares of
beneficial interest as the Board of Trustees deems reasonably necessary to
comply with the provisions of the Code applicable to a REIT, to determine the
Company's status as a REIT, to comply with the requirements of any taxing
authority or governmental agency or to determine any such compliance.
 
  These ownership limitations could have the effect of discouraging a takeover
or other transaction in which holders of some, or a majority, of the Common
Shares might receive a premium for their shares over the then prevailing
market price or which such holders might believe to be otherwise in their best
interest.
 
SHAREHOLDER LIABILITY
 
  Both Maryland statutory law governing real estate investment trusts
organized under the laws of that state and the Declaration of Trust provide
that no shareholder of the Company will be personally liable for any
obligations of the Company (other than the obligation to pay to the Company
the consideration for which shares were or are to be issued) solely by virtue
of his status as a shareholder. The Declaration of Trust further provides that
the Company shall indemnify each shareholder against claims or liabilities to
which the shareholder may become subject by reason of his being or having been
a shareholder, and that the Company shall reimburse each shareholder for all
legal and other expenses reasonably incurred by him in connection with any
such claim or liability, unless such claim or liability arises out of the
shareholder's bad faith, willful misconduct or gross negligence, and provided
that the shareholder gives prompt notice as to any such claims or liabilities
and takes such action as will permit the Company to conduct the defense
thereof. In addition, it is the Company's policy to include a clause in its
contracts which provides that shareholders assume no personal liability for
obligations entered into on behalf of the Company. However, with respect to
tort claims, contractual claims where shareholder liability is not so negated,
claims for taxes and certain statutory liability, a shareholder may, in some
jurisdictions, be personally liable to the extent that such claims are not
satisfied by the Company. Inasmuch as the Company carries public liability
insurance which it considers adequate, any risk of personal liability to
shareholders is limited to situations in which the Company's assets plus its
insurance coverage would be insufficient to satisfy the claims against the
Company and its shareholders.
 
TRANSFER AGENT AND REGISTRAR
 
  Boatmen's Trust Company (510 Locust Street, St. Louis, Missouri 63178) has
been appointed as transfer agent and registrar for the Common Shares.
 
                     DESCRIPTION OF COMMON SHARE WARRANTS
 
  The Company may issue Common Share Warrants for the purchase of Common
Shares. Common Share Warrants may be issued independently or together with any
other Offered Securities offered by any Prospectus Supplement and may be
attached to or separate from such Offered Securities. Each series of Common
Share Warrants will be issued under a separate warrant agreement (each, a
"Warrant Agreement") to be entered into between the Company and a warrant
agent specified in the applicable Prospectus Supplement (the "Warrant Agent").
The Warrant Agent will act solely as an agent of the Company in connection
with the Common Share Warrants of such series and will not assume any
obligation or relationship of agency or trust for or with any holders or
beneficial owners of Common Share Warrants. The following summaries of certain
provisions of the Warrant Agreement and the Common Share Warrants do not
purport to be complete and are subject to, and are qualified in their entirety
by reference to, all the provisions of the Warrant Agreement and the Common
Share Warrant certificates relating to each series of Common Share Warrants,
which will be filed, at or prior to the time of the issuance of such series of
Common Share Warrants, with the Commission as exhibits to a document
incorporated by reference in this Prospectus.
 
                                       6
<PAGE>
 
  If Common Share Warrants are offered, the applicable Prospectus Supplement
will describe the terms of such Common Share Warrants, including the following
where applicable: (i) the offering price; (ii) the aggregate number of Common
Shares purchasable upon exercise of such Common Share Warrants and the
exercise price; (iii) whether such Common Share Warrants are being offered
with Common Shares and the number of such Common Share Warrants being offered
with such Common Shares; (iv) the date, if any, on and after which such Common
Share Warrants and the related Common Shares will be transferable separately;
(v) the date on which the right to exercise such Common Share Warrants shall
commence and the date on which such right shall expire (the "Expiration
Date"); (vi) any special United States Federal income tax consequences; and
(vii) any other material terms of such Common Share Warrants.
 
  Common Share Warrant certificates may be exchanged for new Common Share
Warrant certificates of different denominations, may (if in registered form)
be presented for registration of transfer, and may be exercised at the
corporate trust office of the Warrant Agent or any other office indicated in
the applicable Prospectus Supplement. Prior to the exercise of any Common
Share Warrants to purchase Common Shares, holders of such Common Share
Warrants will not have any rights of holders of such Common Shares, including
the right to receive payments of dividends, if any, on such Common Shares, or
to exercise any applicable right to vote.
 
  To protect the Company's status as a REIT, restrictions on ownership of
Common Share Warrants similar to the restrictions on ownership of Common
Shares will be imposed and enforced. See "Description of Common Shares--
Restrictions on Transfer."
 
EXERCISE OF COMMON SHARE WARRANTS
 
  Each Common Share Warrant will entitle the holder thereof to purchase such
number of Common Shares at such exercise price as shall in each case be set
forth in, or calculable from, the Prospectus Supplement relating to the
offered Common Share Warrants. After the close of business on the Expiration
Date (or such later date to which such Expiration Date may be extended by the
Company), unexercised Common Share Warrants will become void.
 
  Common Share Warrants may be exercised by delivering to the Warrant Agent
payment as provided in the applicable Prospectus Supplement of the amount
required to purchase the Common Shares purchasable upon such exercise together
with certain information set forth on the reverse side of the Common Share
Warrant certificate. Common Share Warrants will be deemed to have been
exercised upon receipt of payment of the exercise price, subject to the
receipt within five (5) business days of the Common Share Warrant certificate
evidencing such Common Share Warrants. Upon receipt of such payment and the
Common Share Warrant certificate properly completed and duly executed at the
corporate trust office of the Warrant Agent or any other office indicated in
the applicable Prospectus Supplement, the Company will, as soon as
practicable, issue and deliver the Common Shares purchasable upon such
exercise. If fewer than all of the Common Share Warrants represented by such
Common Share Warrant certificate are exercised, a new Common Share Warrant
certificate will be issued for the remaining amount of Common Share Warrants.
 
AMENDMENTS AND SUPPLEMENTS TO WARRANT AGREEMENT
 
  The Warrant Agreements may be amended or supplemented without the consent of
the holders of the Common Share Warrants issued thereunder to effect changes
that are not inconsistent with the provisions of the Common Share Warrants and
that do not adversely affect the interests of the holders of the Common Share
Warrants.
 
ADJUSTMENTS
 
  Unless otherwise indicated in the applicable Prospectus Supplement, the
exercise price of, and the number of Common Shares covered by, a Common Share
Warrant are subject to adjustment in certain events, including (i) payment of
a dividend on the Common Shares payable in shares of beneficial interest and
share splits,
 
                                       7
<PAGE>
 
combinations or reclassifications of the Common Shares; (ii) issuance to all
holders of Common Shares of rights or warrants to subscribe for or purchase
Common Shares at less than their current market price (as defined in the
Warrant Agreement for such series of Common Share Warrants); and (iii) certain
distributions of evidences of indebtedness or assets (including securities but
excluding cash distributions paid out of consolidated earnings or retained
earnings or dividends payable in Common Shares) or of subscription rights and
warrants (excluding those referred to above).
 
  No adjustment in the exercise price of, and the number of Common Shares
covered by, a Common Share Warrant will be made for regular quarterly or other
periodic or recurring cash dividends or distributions or for cash dividends or
distributions to the extent paid from consolidated earnings or retained
earnings. No adjustment will be required unless such adjustment would require
a change of at least 1% in the exercise price then in effect. Except as stated
above, the exercise price of, and the number of Common Shares covered by, a
Common Share Warrant will not be adjusted for the issuance of Common Shares or
any securities convertible into or exchangeable for Common Shares, or carrying
the right or option to purchase or otherwise acquire the foregoing, in
exchange for cash, other property or services.
 
  In the event of any (i) consolidation or merger of the Company with or into
any entity (other than a consolidation or a merger that does not result in any
reclassification, conversion, exchange or cancellation of outstanding Common
Shares); (ii) sale, transfer, lease or conveyance of all or substantially all
of the assets of the Company; or (iii) reclassification, capital
reorganization or change of the Common Shares (other than solely a change in
par value or from par value to no par value), then any holder of a Common
Share Warrant will be entitled, on or after the occurrence of any such event,
to receive on exercise of such Common Share Warrant the kind and amount of
shares of beneficial interest or other securities, cash or other property (or
any combination thereof) that the holder would have received had such holder
exercised such holder's Common Share Warrant immediately prior to the
occurrence of such event. If the consideration to be received upon exercise of
the Common Share Warrant following any such event consists of common shares of
the surviving entity, then from and after the occurrence of such event, the
exercise price of such Common Share Warrant will be subject to the same anti-
dilution and other adjustments described in the second preceding paragraph,
applied as if such common shares were Common Shares.
 
                  DESCRIPTION OF SHAREHOLDER PURCHASE RIGHTS
 
  As set forth under "Plan of Distribution" below, the Company may sell the
Offered Securities to investors directly through Shareholder Purchase Rights.
If Offered Securities are to be sold through Shareholder Purchase Rights, such
Shareholder Purchase Rights will be distributed as a dividend to the Company's
shareholders for which shareholders will pay no separate consideration. The
Prospectus Supplement with respect to the offer of Offered Securities pursuant
to Shareholder Purchase Rights will set forth the relevant terms of the
Shareholder Purchase Rights, including (i) whether Common Shares or Common
Share Warrants, or both, will be offered pursuant to the Shareholder Purchase
Rights and the number of Common Shares and Common Share Warrants, as
applicable, which will be offered pursuant to the Shareholder Purchase Rights,
(ii) the period during which and the price at which the Shareholder Purchase
Rights will be exercisable, (iii) the number of Shareholder Purchase Rights
then outstanding, (iv) any provisions for changes to or adjustments in the
exercise price of the Shareholder Purchase Rights and (v) any other material
terms of the Shareholder Purchase Rights. See "Plan of Distribution."

                   CERTAIN PROVISIONS OF MARYLAND LAW AND OF
                 THE COMPANY'S DECLARATION OF TRUST AND BYLAWS
 
  The following paragraphs summarize material provisions of Maryland law, the
Declaration of Trust and the Bylaws. The summary does not purport to be
complete and reference is made to Maryland law as well as the Declaration of
Trust and the Bylaws, which are filed as exhibits to the Registration
Statement of which this Prospectus is a part.
 
BOARD OF TRUSTEES
 
  The Declaration of Trust and the Bylaws provide that the number of Trustees
of the Company may be established by a majority of a quorum of the entire
Board of Trustees but may not be fewer than three nor more than fifteen. The
Declaration of Trust provides that a majority of the Trustees must be persons
who are not affiliated with any member of the Burnam Family or officers or
employees of the Company ("Independent Trustees"). Any vacancy on the Board of
Trustees will be filled, at any regular meeting or at any special meeting
called for that purpose, by a majority of the remaining Trustees (even if less
than a quorum), except that a vacancy resulting from an increase in the number
of Trustees will be filled by a majority of the entire Board of Trustees and,
in the event that a majority of the Board of Trustees are not Independent
Trustees by reason of the resignation or removal of one or more Independent
Trustees or otherwise, the remaining Independent Trustees (or, if there are no
Independent Trustees, the remaining members of the Board of Trustees) shall
promptly elect that number of Independent Trustees necessary to cause the
Board of Trustees to include a majority of Independent Trustees.
 
  Pursuant to the terms of the Declaration of Trust, the Trustees are divided
into three classes, holding office initially for one-year, two-year and three-
year terms, respectively. As these initial terms expire, Trustees in each
class are elected for terms of three years and until their successors are duly
elected and qualified. The Company believes that classification of the Board
of Trustees will help to assure the continuity and stability of the Company's
business strategies and policies as determined by the Board of Trustees.
 
  The classified Trustee provision could have the effect of making the removal
of incumbent Trustees more time-consuming and difficult, which could
discourage a third party from making a tender offer or otherwise attempting to
obtain control of the Company, even though such an attempt might be beneficial
to the Company and its shareholders. At least two annual meetings of
shareholders, instead of one, will generally be required to effect a change in
a majority of the Board of Trustees.
 
  Holders of Common Shares have no right to cumulative voting for the election
of Trustees. Consequently, at each annual meeting of shareholders, the holders
of a majority of Common Shares voting together as a single class will be able
to elect all of the successors of the Trustees whose terms expire at that
meeting. Trustees may be removed at any time by the affirmative vote of the
holders of two-thirds of the Common Shares.
 
BUSINESS COMBINATIONS
 
  Under the Maryland General Corporation Law, as amended from time to time
(the "MGCL"), as applicable to Maryland real estate investment trusts, certain
"business combinations" (including a merger, consolidation, share exchange,
or, in certain circumstances, an asset transfer or issuance or
reclassification of equity securities) between a Maryland real estate
investment trust and any person who beneficially owns 10% or more of the
voting power of the shares of the trust or an affiliate of the trust who, at
any time within the two-year period prior to the date in question, was the
beneficial owner of 10% or more of the voting power of the then-outstanding
voting shares of beneficial interest of the trust (an "Interested
Shareholder") or an affiliate thereof are prohibited for five years after the
most recent date on which the Interested Shareholder became an Interested
Shareholder. Thereafter, any such business combination must be (a) recommended
by the Board of Trustees of such trust and (b) approved by the affirmative
vote of at least (i) 80% of the votes entitled to be cast by holders of
outstanding voting shares of the trust and (ii) two-thirds of the votes
entitled to be cast by holders of outstanding voting
 
                                       9
<PAGE>
 
shares (other than voting shares held by the Interested Shareholder with whom
the business combination is to be effected or by an affiliate or associate
thereof), voting together as a single group, unless, among other things, the
company's common shareholders receive a minimum price (as defined in the
statute) for their shares and the consideration is received in cash or in the
same form as previously paid by the Interested Shareholder for his shares.
These provisions of Maryland law do not apply, however, to business
combinations with a particular Interested Shareholder or its existing or
future affiliates that are approved or exempted by the board of trustees of
the trust prior to the time that the Interested Shareholder becomes an
Interested Shareholder or if the original declaration of trust includes a
provision electing not to be governed, in whole or in part, as to business
combinations generally, specifically or generally by types, as to identified
or unidentified existing or future Interested Shareholders or their
affiliates. The Declaration of Trust, in accordance with Maryland law, exempts
the Burnam Family from the foregoing restrictions. As a result, members of the
Burnam Family may be able to enter into business combinations with the
Company, which may not be in the best interests of the shareholders, without
compliance by the Company with the super-majority voting requirements and the
other provisions of the statute.
 
CONTROL SHARE ACQUISITIONS
 
  The MGCL, as applicable to Maryland real estate investment trusts, imposes
limitations on the voting rights of shares acquired in a "control share
acquisition" relating to a Maryland real estate investment trust. The MGCL
defines a "control share acquisition" as the acquisition of "control shares,"
which is defined as voting shares that would entitle the acquiror to exercise
voting power in electing trustees in excess of the following levels of voting
power: 20%, 33 1/3%, and 50%. The MGCL requires a two-thirds shareholder vote
(excluding shares owned by the acquiring person and certain members of
management) to accord voting rights to shares acquired in a control share
acquisition. The MGCL also requires a Maryland real estate investment trust to
hold a special meeting at the request of an actual or proposed control share
acquiror generally within 50 days after a request is made with the submission
of an "acquiring person statement," but only if the acquiring person (a)
delivers a written undertaking to pay the expenses of such special meeting or,
if required by the Board of Trustees, posts a bond for the cost of the meeting
and (b) submits a definitive financing agreement to the extent that financing
is not provided by the acquiring person. In addition, unless the charter or
bylaws provide otherwise, the MGCL gives a Maryland real estate investment
trust, within certain time limitations, various redemption rights if there is
a shareholder vote on the issue and the grant of voting rights is not
approved, or if an "acquiring person statement" is not delivered to the target
company within 10 days following a control share acquisition. Moreover, unless
the charter or bylaws provide otherwise, the MGCL provides that if, before a
control share acquisition occurs, voting rights are accorded to the control
shares which results in the acquiring person having a majority of voting
power, then minority shareholders are entitled to appraisal rights. The fair
value of the shares as determined for purposes of such appraisal rights may
not be less than the highest price per share paid by the acquiror in the
control share acquisition. The control share acquisition statute does not
apply (a) to shares acquired in a merger, consolidation or share exchange if
the trust is a party to the transaction or (b) to acquisitions approved or
exempted by the declaration of trust or bylaws of the trust. The Declaration
of Trust, in accordance with Maryland law, contains a provision exempting
acquisitions of shares by the Burnam Family from the foregoing provisions.
 
AMENDMENT TO THE DECLARATION OF TRUST
 
  The Declaration of Trust may be amended only by the affirmative vote or
written consent of the holders of not less than a majority of all of the
shares of beneficial interest entitled to vote on the matter, except that the
Trustees by a two-thirds vote may amend provisions of the Declaration of Trust
from time to time to qualify as a real estate investment trust under the Code
and the Maryland REIT Law.
 
TERMINATION OF THE COMPANY
 
  The Declaration of Trust permits the termination of the Company and the
discontinuation of the operations of the Company by the affirmative vote or
written consent of the holders of not less than two-thirds of the outstanding
shares of beneficial interest.
 
                                      10
<PAGE>
 
ADVANCE NOTICE OF TRUSTEE NOMINATIONS AND NEW BUSINESS
 
  The Bylaws provide that (a) with respect to an annual meeting of
shareholders, nominations of persons for election to the Board of Trustees and
the proposal of business to be considered by shareholders may be made only (i)
pursuant to the Company's notice of the meeting, (ii) by or at the direction
of the Board of Trustees, or (iii) by a shareholder who is entitled to vote at
the meeting and has complied with the advance notice procedures set forth in
the Bylaws, and (b) with respect to special meetings of shareholders, only the
business specified in the Company's notice of meeting may be brought before
the meeting of shareholders, and, if the Board of Trustees has determined that
Trustees shall be elected at any such meeting, nominations of persons for
election to the Board of Trustees may be made only on terms similar to those
for annual meetings.
 
ANTI-TAKEOVER EFFECT OF CERTAIN PROVISIONS OF MARYLAND LAW AND OF THE
DECLARATION OF TRUST AND BYLAWS
 
  The business combination provisions and the control share acquisition
provisions of the MGCL, the provisions of the Declaration of Trust on
classification of the Board of Trustees and removal of Trustees and the
advance notice provisions of the Bylaws could delay, defer or prevent a
transaction or a change in control of the Company that might involve a premium
price for holders of Common Shares or otherwise be in their best interest.
 
                       FEDERAL INCOME TAX CONSIDERATIONS
 
  The following is a description of the material Federal income tax
consequences to the Company and its shareholders of the treatment of the
Company as a REIT. The discussion is general in nature and not exhaustive of
all possible tax considerations, nor does the discussion give a detailed
description of any state, local, or foreign tax considerations. The discussion
does not discuss all aspects of Federal income tax law that may be relevant to
a prospective shareholder in light of his particular circumstances or to
certain types of shareholders (including insurance companies, financial
institutions or broker-dealers, tax exempt organizations, foreign corporations
and persons who are not citizens or residents of the United States) subject to
special treatment under the Federal income tax laws nor does the discussion
address special considerations, if any, which may relate to the purchase of
Common Share Warrants.
 
  THIS DISCUSSION IS NOT INTENDED AS A SUBSTITUTE FOR CAREFUL TAX PLANNING,
AND EACH PROSPECTIVE INVESTOR IS ADVISED TO CONSULT WITH ITS TAX ADVISOR
REGARDING THE SPECIFIC TAX CONSEQUENCES TO IT OF THE PURCHASE, OWNERSHIP AND
SALE OF THE SECURITIES OFFERED HEREBY, INCLUDING THE FEDERAL, STATE, LOCAL,
FOREIGN AND OTHER TAX CONSEQUENCES OF SUCH PURCHASE, OWNERSHIP AND SALE, AND
OF POTENTIAL CHANGES IN APPLICABLE TAX LAWS.
 
  If certain detailed conditions imposed by the REIT provisions of the Code
are met, entities, such as the Company, that invest primarily in real estate
and that otherwise would be treated for Federal income tax purposes as
corporations, are generally not taxed at the corporate level on their "REIT
taxable income" that is currently distributed to shareholders. This treatment
substantially eliminates the "double taxation" (i.e., at both the corporate
and shareholder levels) that generally results from the use of corporations.
 
  If the Company fails to qualify as a REIT in any year, however, it will be
subject to Federal income taxation as if it were a domestic corporation, and
its shareholders will be taxed in the same manner as shareholders of ordinary
corporations. In this event, the Company could be subject to potentially
significant tax liabilities, and therefore the amount of cash available for
distribution to its shareholders would be reduced or eliminated.
 
                                      11
<PAGE>
 
  The Company has elected REIT status effective for the taxable year ended
December 31, 1994, and the Board of Trustees of the Company believes that the
Company has operated and expects that the Company will continue to operate in
a manner that has enabled the Company to qualify as a REIT and will permit the
Company to maintain its REIT status in each taxable year thereafter. There can
be no assurance, however, that this belief or expectation will be fulfilled,
since qualification as a REIT depends on the Company continuing to satisfy
numerous asset, income and distribution tests described below, which in turn
will be dependent in part on the Company's operating results.
 
TAXATION OF THE COMPANY
 
  General. In any year in which the Company qualifies as a REIT it will not,
in general, be subject to Federal income tax on that portion of its REIT
taxable income or capital gain which is distributed to shareholders. The
Company may, however, be subject to tax at normal corporate rates upon any
taxable income or capital gain not distributed.
 
  Notwithstanding its qualification as a REIT, the Company may also be subject
to taxation in certain other circumstances. If the Company should fail to
satisfy either the 75% or the 95% gross income test (as discussed below), and
nonetheless maintains its qualification as a REIT because certain other
requirements are met, it will be subject to a 100% tax on the greater of the
amount by which the Company fails either the 75% or the 95% test, multiplied
by a fraction intended to reflect the Company's profitability. The Company
will also be subject to a tax of 100% on net income from any "prohibited
transaction" as described below, and if the Company has (i) net income from
the sale or other disposition of "foreclosure property" which is held
primarily for sale to customers in the ordinary course of business or (ii)
other non-qualifying income from foreclosure property, it will be subject to
tax on such income from foreclosure property at the highest corporate rate. In
addition, if the Company 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 years, the Company would be subject to
a 4% excise tax on the excess of such required distribution over the amounts
actually distributed. The Company may also be subject to the corporate
alternative minimum tax, as well as tax in certain situations not presently
contemplated. The Subsidiary Company will be taxed on its income at regular
corporate rates. The Company will use the calendar year both for Federal
income tax purposes and for financial reporting purposes.
 
  In order to qualify as a REIT, the Company must meet, among others, the
following requirements:
 
  Share Ownership Tests. The Company's shares of beneficial interest must be
held by a minimum of 100 persons for at least 335 days in each taxable year
(or a proportional number of days in any short taxable year). In addition, at
all times during the second half of each taxable year, no more than 50% in
value of the outstanding shares of beneficial interest of the Company may be
owned, directly or indirectly and by applying certain constructive ownership
rules, by five or fewer individuals, which for this purpose includes certain
tax-exempt entities. However, for purposes of this test, any shares of
beneficial interest held by a qualified domestic pension or other retirement
trust will be treated as held directly by its beneficiaries in proportion to
their actuarial interest in such trust rather than by such trust. These share
ownership requirements need not be met until the second taxable year of the
Company for which a REIT election is made.
 
  In order to attempt to ensure compliance with the foregoing share ownership
tests, the Company has placed certain restrictions on the transfer of its
shares of beneficial interest to prevent additional concentration of share
ownership. Moreover, to evidence compliance with these requirements, under
Treasury regulations the Company must maintain records which disclose the
actual ownership of its outstanding shares of beneficial interest. In
fulfilling its obligations to maintain records, the Company must and will
demand written statements each year from the record holders of designated
percentages of its shares of beneficial interest disclosing the actual owners
of such shares of beneficial interest (as prescribed by Treasury regulations).
A list of those persons failing or refusing to comply with such demand must be
maintained as a part of the Company's records. A shareholder failing or
refusing to comply with the Company's written demand must submit with his tax
return a similar
 
                                      12
<PAGE>
 
statement disclosing the actual ownership of Company shares of beneficial
interest and certain other information. In addition, the Declaration of Trust
provides restrictions regarding the transfer of its shares of beneficial
interest that are intended to assist the Company in continuing to satisfy the
share ownership requirements. See "Description of Common Shares--Restrictions
on Transfer."
 
  Asset Tests. At the close of each quarter of the Company's taxable year, the
Company must satisfy two tests relating to the nature of its assets (with
"assets" being determined in accordance with generally accepted accounting
principles). First, at least 75% of the value of the Company's total assets
must be represented by interests in real property, interests in mortgages on
real property, shares in other REITs, cash, cash items, government securities
and qualified temporary investments. Second, although the remaining 25% of the
Company's assets generally may be invested without restriction, securities in
this class may not exceed (i) in the case of securities of any one non-
government issuer, 5% of the value of the Company's total assets or (ii) 10%
of the outstanding voting securities of any one such issuer. Where the Company
invests in a partnership (such as the Operating Partnership), it will be
deemed to own a proportionate share of the partnership's assets. See "--Tax
Aspects of the Company's Investments in Partnerships--General." Accordingly,
the Company's investment in the Facilities through its interest in the
Operating Partnership is intended to constitute an investment in qualified
assets for purposes of the 75% asset test.
 
  The Operating Partnership owns 100% of the non-voting preferred stock and 5%
of the voting stock of the Subsidiary Company. See "The Company." By virtue of
its partnership interest in the Operating Partnership, the Company is deemed
to own its pro rata share of the assets of the Operating Partnership,
including the securities of the Subsidiary Company, as described above.
Because the Operating Partnership owns only 5% of the voting securities of the
Subsidiary Company, and the preferred stock's approval right is limited to
certain fundamental corporate actions that could adversely affect the
preferred stock as a class, the 10% limitation on holdings of voting
securities of any one issuer should not be exceeded.
 
  Based upon its analysis of the total estimated value of the Subsidiary
Company stock owned by the Operating Partnership relative to the estimated
value of the total assets owned by the Operating Partnership and the other
assets of the Company, the Company believes that the Company's pro rata share
of the stock of the Subsidiary Company owned by the Operating Partnership does
not exceed, on the date of this Prospectus, 5% of the value of the Company's
total assets. This 5% limitation must be satisfied not only as of the date
that the Company (directly or through the Operating Partnership) acquired
securities of the Subsidiary Company, but also at the end of any quarter in
which the Company increases its interest in the Subsidiary Company or so
acquires other property. In this respect, if the holder of a right to exchange
Units for Common Shares, including BHC or an Original Investor, exercises such
rights, the Company will thereby increase its proportionate (indirect)
ownership interest in the Subsidiary Company, thus requiring the Company to
meet the 5% test in any quarter in which such conversion option is exercised.
A similar result will follow in the case of any exchange of Units by Operating
Partnership or Subsidiary Company employees that they received pursuant to the
option plan established by the Company. Although the Company plans to take
steps to ensure that it satisfies the 5% value test for any quarter with
respect to which retesting is to occur, there can be no assurance that such
steps will always be successful or will not require a reduction in the
Operating Partnership's overall interest in the Subsidiary Company.
 
  Gross Income Tests. There are three separate percentage tests relating to
the sources of the Company's gross income which must be satisfied for each
taxable year. For purposes of these tests, where the Company invests in a
partnership, the Company will be treated as receiving its share of the income
and loss of the partnership, and the gross income of the partnership will
retain the same character in the hands of the Company as it has in the hands
of the partnership. See "--Tax Aspects of the Company's Investments in
Partnerships--General" below. The three tests are as follows:
 
  The 75% Test. At least 75% of the Company's gross income for the taxable
year must be "qualifying income." Qualifying income generally includes (i)
rents from real property (except as modified below); (ii) interest on
obligations secured by mortgages on, or interests in, real property; (iii)
gains from the sale or other
 
                                      13
<PAGE>
 
disposition of interests in real property and real estate mortgages, other
than gain from property held primarily for sale to customers in the ordinary
course of the Company's trade or business ("dealer property"); (iv) dividends
or other distributions on shares in other REITs, as well as gain from the sale
of such shares; (v) abatements and refunds of real property taxes; (vi) income
from the operation, and gain from the sale, of property acquired at or in lieu
of a foreclosure of the mortgage secured by such property ("foreclosure
property"); (vii) commitment fees received for agreeing to make loans secured
by mortgages on real property or to purchase or lease real property; and
(viii) certain qualified temporary investment income attributable to the
investment of new capital received by the Company in exchange for its shares
during the one-year period following the receipt of such capital.
 
  Rents received from a customer will not, however, qualify as rents from real
property in satisfying the 75% test (or the 95% gross income test described
below) if the Company, or an owner of 10% or more of the Company, directly or
constructively owns 10% or more of such tenant. In addition, 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. Moreover, an amount received or accrued will not
qualify as rents from real property (or as interest income) for purposes of
the 75% and 95% gross income tests if it is based in whole or in part on the
income or profits of any person, although an amount received or accrued
generally will not be excluded from "rents from real property" solely by
reason of being based on a fixed percentage or percentages of receipts or
sales. Finally, for rents received to qualify as rents from real property for
purposes of the 75% and 95% gross income tests, the Company generally must not
operate or manage the property or furnish or render services to tenants, other
than through an "independent contractor" from whom the Company derives no
income, except that the "independent contractor" requirement does not apply to
the extent that the services provided by the Company are "usually or
customarily rendered" in connection with the rental of space for occupancy
only, or are not otherwise considered "rendered to the occupant for his
convenience."
 
  The Company intends to monitor its operations in the context of these
standards so as to satisfy the 75% and 95% gross income tests. The Operating
Partnership provides certain services at the Facilities it owns and may
provide certain services at any newly acquired self-storage facilities of the
Operating Partnership. The Company believes for purposes of the 75% and 95%
gross income tests, that the services provided at such facilities and any
other services and amenities provided by the Operating Partnership or its
agents with respect to such facilities are and will continue to be of the type
usually or customarily rendered in connection with the rental of space for
occupancy only. The Company intends that services that cannot be provided
directly by the Operating Partnership, the Subsidiary Company or other agents
will be performed by independent contractors.
 
  The 95% Test. In addition to deriving 75% of its gross income from the
sources listed above, at least 95% of the Company's gross income for the
taxable year must be derived from the above-described qualifying income, or
from dividends, interest, or gains from the sale or other disposition of stock
or other securities that are not dealer property. Dividends and interest on
any obligations not collateralized by an interest in real property are
included for purposes of the 95% test, but not for purposes of the 75% test.
The Company intends to closely monitor its non-qualifying income and
anticipates that non-qualifying income from its other activities will not
result in the Company failing to satisfy either the 75% or 95% gross income
test. The Operating Partnership owns partnership interests in certain joint
ventures which own certain Facilities. No assurance can be given that such
partnerships will not realize non-qualifying income, in which case the
Operating Partnership's distributive share of such income would be non-
qualifying income.
 
  For purposes of determining whether the Company complies with the 75% and
the 95% gross income tests, gross income does not include income from
prohibited transactions. A "prohibited transaction" is a sale of dealer
property (excluding foreclosure property); however, it does not include a sale
of property if such property is held by the Company for at least four years
and certain other requirements (relating to the number of properties sold in a
year, their tax bases, and the cost of improvements made thereto) are
satisfied. See "--Taxation of the Company--General" and "--Tax Aspects of the
Company's Investments in Partnerships--Sale of the Facilities."
 
 
                                      14
<PAGE>
 
  The Company believes that, for purposes of both the 75% and the 95% gross
income tests, its investment in the Facilities through the Operating
Partnership will in major part give rise to qualifying income in the form of
rents, and that gains on sales of the Facilities, or of the Company's interest
in the Operating Partnership, generally will also constitute qualifying
income.
 
  Even if the Company fails to satisfy one or both of the 75% or 95% gross
income tests for any taxable year, it may still qualify as a REIT for such
year if it is entitled to relief under certain provisions of the Code. These
relief provisions will generally be available if: (i) the Company's failure to
comply was due to reasonable cause and not to willful neglect; (ii) the
Company reports the nature and amount of each item of its income included in
the tests on a schedule attached to its tax return; and (iii) any incorrect
information on this schedule is not due to fraud with intent to evade tax. If
these relief provisions apply, however, the Company will nonetheless be
subject to a 100% tax on the greater of the amount by which it fails either
the 75% or 95% gross income test, multiplied by a fraction intended to reflect
the Company's profitability.
 
  The 30% Test. The Company must derive less than 30% of its gross income for
each taxable year from the sale or other disposition of (i) real property held
for less than four years (other than foreclosure property and involuntary
conversions); (ii) stock or securities (including an interest rate swap or cap
agreement) held for less than one year; and (iii) property in a prohibited
transaction. The Company does not anticipate that it will have difficulty in
complying with this test. However, if extraordinary circumstances were to
occur that give rise to dispositions of self-storage facilities held for less
than four years (for example, on account of the inability to obtain
refinancing), the 30% test could become an issue.
 
  Annual Distribution Requirements. In order to qualify as a REIT, the Company
is required to distribute dividends (other than capital gain dividends) to its
shareholders each year in an amount at least equal to (A) the sum of (i) 95%
of the Company's REIT taxable income (computed without regard to the dividends
paid deduction and the Company's net capital gain) and (ii) 95% of the net
income (after tax), if any, from foreclosure property, minus (B) the sum of
certain items of non-cash income. Such distributions must be paid in the
taxable year to which they relate, or in the following taxable year if
declared before the Company timely files its tax return for such year and if
paid on or before the first regular dividend payment after such declaration.
To the extent that the Company does not distribute all of its net capital gain
or distributes at least 95%, but less than 100%, of its REIT taxable income,
as adjusted, it will be subject to tax on the undistributed amount at regular
capital gains or ordinary corporate tax rates, as the case may be.
 
  The Company intends to make timely distributions sufficient to satisfy the
annual distribution requirements described in the first sentence of the
preceding paragraph. In this regard, the Partnership Agreement authorizes the
Company, as general partner, to take such steps as may be necessary to cause
the Operating Partnership to distribute to its partners an amount sufficient
to permit the Company to meet these distribution requirements. It is possible
that the Company may not have sufficient cash or other liquid assets to meet
the 95% distribution requirement, due to timing differences between the actual
receipt of income and actual payment of expenses on the one hand, and the
inclusion of such income and deduction of such expenses in computing the
Company's REIT taxable income on the other hand; due to the Operating
Partnership's inability to control cash distributions with respect to any
properties as to which it does not have decision making control; or for other
reasons. To avoid a problem with the 95% distribution requirement, the Company
will closely monitor the relationship between its REIT taxable income and cash
flow and, if necessary, intends to borrow funds (or cause the Operating
Partnership or other affiliates to borrow funds) in order to satisfy the
distribution requirement. However, there can be no assurance that such
borrowing would be available at such time.
 
  If the Company fails to meet the 95% distribution requirement as a result of
an adjustment to the Company's tax return by the Service, the Company may
retroactively cure the failure by paying a "deficiency dividend" (plus
applicable penalties and interest) within a specified period.
 
                                      15
<PAGE>
 
  Failure to Qualify. If the Company fails to qualify for taxation as a REIT
in any taxable year and the relief provisions do not apply, the Company will
be subject to tax (including any applicable alternative minimum tax) on its
taxable income at regular corporate rates. Distributions to shareholders in
any year in which the Company fails to qualify as a REIT will not be
deductible by the Company, nor generally will they be required to be made
under the Code. In such event, to the extent of current and accumulated
earnings and profits, all distributions to shareholders will be taxable as
ordinary income, and, subject to certain limitations in the Code, corporate
distributees may be eligible for the dividends received deduction. Unless
entitled to relief under specific statutory provisions, the Company also will
be disqualified from re-electing taxation as a REIT for the four taxable years
following the year during which qualification was lost.
 
TAX ASPECTS OF THE COMPANY'S INVESTMENTS IN PARTNERSHIPS
 
  General. The Company holds a partnership interest in the Operating
Partnership. See "The Company." In addition, the Operating Partnership owns
partnership interests in several joint venture partnerships which own certain
Facilities. In general, a partnership is a "pass-through" entity which is not
subject to Federal income tax. Rather, partners are allocated their
proportionate shares of the items of income, gain, loss, deduction and credit
of a partnership, and are potentially subject to tax thereon, without regard
to whether the partners receive a distribution from the partnership. The
Company will include its proportionate share of the foregoing partnership
items for purposes of the various REIT gross income tests and in the
computation of its REIT taxable income. See "--Taxation of the Company--
General" and "--Gross Income Tests."
 
  Each partner's share of a partnership's tax attributes is determined in
accordance with the partnership agreement, although the allocations will be
adjusted for tax purposes if they do not comply with the technical provisions
of Code Section 704(b) and the regulations thereunder. The Operating
Partnership's allocations of tax attributes are intended to comply with these
provisions. Notwithstanding these allocation provisions, for purposes of
complying with the gross incomes tests discussed above, the Company will be
deemed to have received a share of the income of the Partnership based on its
capital interest in the Operating Partnership.
 
  Also, any resultant increase in the Company's REIT taxable income from its
interest in the Operating Partnership (whether or not a corresponding cash
distribution is also received from the Operating Partnership) will increase
its distribution requirements (see "--Taxation of the Company--Annual
Distribution Requirements"), but will not be subject to Federal income tax in
the hands of the Company provided that an amount equal to such income is
distributed by the Company to its shareholders. Moreover, for purposes of the
REIT asset tests (see "--Taxation of the Company--Asset Tests"), the Company
will include its proportionate share of assets held by the Operating
Partnership (including the Operating Partnership's share of assets held
through its interests in the joint venture partnerships).
 
  Entity Classification. The Company's interest in the Operating Partnership
involves special tax considerations, including the possibility of a challenge
by the Service of the status of the Operating Partnership as a partnership (as
opposed to an association taxable as a corporation for Federal income tax
purposes). If the Operating Partnership were to be treated as an association,
it would be taxable as a corporation and therefore subject to an entity-level
tax on its income. In such a situation, the character of the Company's assets
and items of gross income would change, which would preclude the Company from
satisfying the REIT asset tests and the REIT gross income tests (see "--
Taxation of the Company--Asset Tests" and "--Gross Income Tests"), which in
turn would prevent the Company from qualifying as a REIT. (See "--Taxation of
the Company--Failure to Qualify" above, for a discussion of the effect of the
Company's failure to meet such tests.) A similar result could occur if any of
the joint venture partnerships in which the Operating Partnership owns a
partnership interest were classified as associations taxable as corporations.
 
  Tax Allocations with Respect to the Facilities. Pursuant to Section 704(c)
of the Code, income, gain, loss and deduction attributable to appreciated or
depreciated property that is contributed to a partnership in exchange for an
interest in the partnership (such as certain of the Facilities or interests
therein), must be allocated in a manner such that the contributing partner is
charged with, or benefits from, respectively, the unrealized gain or
 
                                      16
<PAGE>
 
unrealized loss associated with the property at the time of the contribution.
The amount of such unrealized gain or unrealized loss is generally equal to
the difference between the fair market value of the contributed property at
the time of contribution, and the adjusted tax basis of such property at the
time of contribution (a "Book-Tax Difference"). Such allocations are solely
for Federal income tax purposes and do not affect the book capital accounts or
other economic arrangements among the partners. The formation of the Operating
Partnership included contributions of appreciated property (including certain
of the Facilities or interests therein). Consequently, the Partnership
Agreement requires certain allocations to be made in a manner consistent with
Section 704(c) of the Code.
 
  In general, certain contributors of certain of the Facilities or interests
therein will be allocated lower amounts of depreciation deductions for tax
purposes and increased taxable income and gain on sale by the Operating
Partnership on the contributed assets (including certain of such Facilities).
This will tend to eliminate the Book-Tax Difference over the life of the
Operating Partnership. However, the special allocation rules of Section 704(c)
do not always entirely rectify the Book-Tax Difference on an annual basis or
with respect to a specific taxable transaction such as a sale or a deemed
sale, and accordingly variations from normal Section 704(c) principles may
arise, which could result in the allocation of additional taxable income to
the Company in excess of corresponding cash proceeds in certain circumstances.
 
  Treasury regulations issued under Section 704(c) of the Code provide
partnerships with a choice of several methods of accounting for Book-Tax
Differences, including retention of the method under current law. The
Operating Partnership and the Company will use the traditional method for
making allocations under Section 704(c) with respect to the existing
Facilities.
 
  With respect to any property purchased by the Operating Partnership
subsequent to the admission of the Company to the Operating Partnership as
well as certain Facilities acquired in taxable transactions, in general, such
property will initially have a tax basis equal to its fair market value and
Section 704(c) of the Code will not apply.
 
  Sale of the Facilities. The Company's share of any gain realized by the
Operating Partnership on the sale of any dealer property generally will be
treated as income from a prohibited transaction that is subject to a 100%
penalty tax. See "Taxation of the Company--General" and "Gross Income Tests--
The 95% Test." Under existing law, whether property is dealer property is a
question of fact that depends on all the facts and circumstances with respect
to the particular transaction. The Operating Partnership intends to hold (and,
to the extent within its control, to have any joint venture in which the
Operating Partnership is a partner so hold) the Facilities for investment with
a view to long-term appreciation, to engage in the business of acquiring,
owning, operating and developing the Facilities and other self-storage
facilities, and to make such occasional sales of the Facilities and other
facilities acquired subsequent to the date hereof as are consistent with the
Company's investment objectives. Based upon the Company's investment
objectives, the Company believes that overall the Facilities should not be
considered dealer property and that the amount of income from prohibited
transactions, if any, will not be material.
 
TAXATION OF SHAREHOLDERS
 
  Taxation of Taxable Domestic Shareholders. As long as the Company qualifies
as a REIT, distributions made to the Company's taxable domestic shareholders
out of current or accumulated earnings and profits (and not designated as
capital gain dividends) will be taken into account by them as ordinary income
and will not be eligible for the dividends received deduction for
corporations. Distributions that are designated as capital gain dividends will
be taxed as long-term capital gains (to the extent they do not exceed the
Company's actual net capital gain for the taxable year) without regard to the
period for which the shareholder has held its shares of beneficial interest of
the Company. However, corporate shareholders may be required to treat up to
20% of certain capital gain dividends as ordinary income. To the extent that
the Company makes distributions in excess of current and accumulated earnings
and profits, these distributions are treated first as a tax-free return of
capital to the shareholder, reducing the tax basis of a shareholder's Common
Shares by the amount of such excess
 
                                      17
<PAGE>
 
distribution (but not below zero), with distributions in excess of the
shareholder's tax basis being taxed as capital gains (if the Common Shares are
held as a capital asset). In addition, any dividend declared by the Company in
October, November or December of any year and payable to a shareholder of
record on a specific date in any such month shall be treated as both paid by
the Company and received by the shareholder on December 31 of such year,
provided that the dividend is actually paid by the Company during January of
the following calendar year. Shareholders may not include in their individual
income tax returns any net operating losses or capital losses of the Company.
Federal income tax rules may also require that certain minimum tax adjustments
and preferences be apportioned to Company shareholders.
 
  In general, any loss upon a sale or exchange of Common Shares by a
shareholder who has held such Common Shares for six months or less (after
applying certain holding period rules) will be treated as a long-term capital
loss, to the extent of distributions from the Company required to be treated
by such shareholder as long-term capital gains.
 
  Backup Withholding. The Company will report to its domestic shareholders and
to the Service the amount of dividends paid for each calendar year, and the
amount of tax withheld, if any, with respect thereto. Under the backup
withholding rules, a shareholder may be subject to backup withholding at the
rate of 31% with respect to dividends paid unless such shareholder (i) is a
corporation or comes within certain other exempt categories and, when
required, demonstrates this fact or (ii) provides a taxpayer identification
number, certifies as to no loss of exemption from backup withholding, and
otherwise complies with applicable requirements of the backup withholding
rules. A shareholder that does not provide the Company with its correct
taxpayer identification number may also be subject to penalties imposed by the
Service. Any amount paid as backup withholding is available as a credit
against the shareholder's income tax liability. In addition, the Company may
be required to withhold a portion of capital gain distributions made to any
shareholders who fail to certify their non-foreign status to the Company. See
"Certain United States Tax Considerations for Non-U.S. Shareholders--
Distributions from the Company--Capital Gain Dividends" below.
 
  Taxation of Tax-Exempt Shareholders. The Service has issued a revenue ruling
in which it held that amounts distributed by a REIT to a tax-exempt employees'
pension trust do not constitute unrelated business taxable income ("UBTI").
Subject to the discussion below regarding a "pension-held REIT," based upon
such ruling and the statutory framework of the Code, distributions by the
Company to a shareholder that is a tax-exempt entity should not constitute
UBTI, provided that the tax-exempt entity has not financed the acquisition of
its shares with "acquisition indebtedness" within the meaning of the Code,
that the shares are not otherwise used in an unrelated trade or business of
the tax-exempt entity, and that the Company, consistent with its present
intent, does not hold a residual interest in a REMIC.
 
  However, if any pension or other retirement trust that qualifies under
Section 401(a) of the Code ("qualified pension trust") holds more than 10% by
value of the interests in a "pension-held REIT" at any time during a taxable
year, a portion of the dividends paid to the qualified pension trust by such
REIT may constitute UBTI. For these purposes, a "pension-held REIT" is defined
as a REIT if (i) such REIT would not have qualified as a REIT but for the
provisions of the Code which look through such a qualified pension trust in
determining ownership of shares of the REIT and (ii) at least one qualified
pension trust holds more than 25% by value of the interests of such REIT or
one or more qualified pension trusts (each owning more than a 10% interest by
value in the REIT) hold in the aggregate more than 50% by value of the
interests in such REIT. The Company does not expect to be a "pension-held
REIT."
 
OTHER TAX CONSIDERATIONS
 
  Subsidiary Company. The income of the Subsidiary Company is subject to
Federal and state income tax at full corporate rates, and the Subsidiary
Company cannot claim a deduction for the dividends it pays to its
shareholders, including the Company. To the extent that the Subsidiary Company
pays Federal, state or local taxes, it will have less cash available to
distribute to its shareholders, thereby reducing cash available for
 
                                      18
<PAGE>
 
distribution by the Company to its shareholders. The Subsidiary Company will
attempt to minimize the amount of such taxes, but there can be no assurance
whether or the extent to which measures taken to minimize taxes will be
successful.
 
  Possible Legislative or Other Actions Affecting Tax Consequences.
Prospective shareholders should recognize that the present Federal income tax
treatment of investment in the Company may be modified by legislative,
judicial or administrative action at any time and that any such action may
affect investments and commitments previously made. The rules dealing with
Federal income taxation are constantly under review by persons involved in the
legislative process and by the Service and the Treasury Department, resulting
in revisions of regulations and revised interpretations of established
concepts as well as statutory changes. No assurance can be given as to the
form or content (including with respect to effective dates) of any tax
legislation which may be enacted. Revisions in Federal tax laws and
interpretations thereof could adversely affect the tax consequences of
investment in the Company.
 
  In particular, the Treasury Department promulgated regulations on December
29, 1994 that would permit the Service to recharacterize transactions
involving partnerships purporting to create tax advantages inconsistent with
the intent of the partnership provisions of the Code. The intended application
of these regulations is uncertain. Nonetheless, although the matter is not
free from doubt, it is believed that these regulations will not adversely
affect the Company's ability to qualify as a REIT.
 
  State and Local Taxes. The Company and its shareholders may be subject to
state or local taxation, and the Company and the Operating Partnership may be
subject to state or local tax withholding requirements, in various
jurisdictions, including those in which it or they transact business or
reside. The state and local tax treatment of the Company and its shareholders
may not conform to the Federal income tax consequences discussed above.
Consequently, prospective shareholders should consult their own tax advisors
regarding the effect of state and local tax laws on an investment in Common
Shares.
 
                   CERTAIN UNITED STATES TAX CONSIDERATIONS
                           FOR NON-U.S. SHAREHOLDERS
 
  The following is a discussion of certain anticipated U.S. Federal income and
U.S. Federal estate tax consequences of the ownership and disposition of
shares of beneficial interest applicable to Non-U.S. Shareholders of such
shares. A "Non-U.S. Shareholder" is (i) any individual who is neither a
citizen nor resident of the United States, (ii) any corporation or partnership
other than a corporation or partnership created or organized in the United
States or under the laws of the United States or any state thereof or under
the laws of the District of Columbia, (iii) any estate the income of which,
from sources without the United States which is not effectively connected with
the conduct of a trade or business within the United States, is not includable
in gross income for United States Federal income tax purposes or (iv) any
trust which is not a "United States Trust". A United States Trust is (a) for
taxable years beginning after December 31, 1996, or if the trustee of a trust
elects to apply the following definition to an earlier taxable year, any trust
if, and only if, (i) a court within the United States is able to exercise
primary supervision over the administration of the trust and (ii) one or more
U.S. trustees have the authority to control all substantial decisions of the
trust, and (b) for all other taxable years, any trust whose income is
includable in gross income for United States Federal income tax purposes
regardless of its source. The discussion is based on current law and is for
general information only. The discussion does not address other aspects of
U.S. Federal taxation other than income and estate taxation or all aspects of
U.S. Federal income and estate taxation. The discussion does not consider any
specific facts or circumstances that may apply to a particular Non-U.S.
Shareholder.

DISTRIBUTIONS FROM THE COMPANY
 
  Ordinary Dividends. The portion of dividends received by Non-U.S.
Shareholders payable out of the Company's earnings and profits that are not
attributable to capital gains of the Company and that are not effectively
connected with a U.S. trade or business of the Non-U.S. Shareholder will be
subject to U.S. withholding tax at the rate of 30% (unless reduced by treaty
or the Non-U.S. Shareholder files an Internal Revenue Service Form 4224 with
the Company certifying that the investment to which the distribution relates
is effectively connected to a United States trade or business of such Non-U.S.
Shareholder). Under certain limited circumstances, the amount of tax withheld
may be refundable, in whole or in part, because of the tax status of certain
partners or beneficiaries of Non-U.S. Shareholders that are either foreign
partnerships or foreign estates or trusts. In general, Non-U.S. Shareholders
will not be considered engaged in a U.S. trade or business solely as a result
of their ownership of shares of beneficial interest. In cases where the
dividend income from a Non-U.S. Shareholder's investment in shares of
beneficial interest is (or is treated as) effectively connected with the Non-
U.S. Shareholder's conduct of a U.S. trade or business, the Non-U.S.
Shareholder generally will be subject to U.S. tax at graduated rates, in the
same manner as U.S. shareholders are taxed with respect to such dividends (and
may also be subject to the 30% branch profits tax (unless reduced by treaty)
in the case of a Non-U.S. Shareholder that is a foreign corporation).
 
  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. Treasury
regulations proposed in 1996, which have not been adopted, and are, therefore,
not currently effective, would, if and when they become effective, require
Non-U.S. Shareholders to file a form W-8 to obtain the benefit of any
applicable tax treaty providing for a lower rate of withholding tax on
dividends paid after December 31, 1997. Such form would require a
representation by the holder as to foreign status, the holder's name and
permanent residence address, the basis for a reduced withholding rate (e.g.,
the relevant tax treaty) and other pertinent information, to be certified by
such holder under penalties of perjury. Such information is subject to being
reported to the Internal Revenue Service. A permanent resident address for
this purpose generally is the address in the country where the person claims
to be a resident for the purpose 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.
 
  Capital Gain Dividends. Under the Foreign Investment in Real Property Tax
Act of 1980 ("FIRPTA"), any distribution made by the Company to a Non-U.S.
Shareholder, to the extent attributable to gains from dispositions of United
States Real Property Interests ("USRPIs") by the Company ("USRPI Capital
Gains"), will be considered effectively connected with a U.S. trade or
business of the Non-U.S. Shareholder and subject to U.S. income tax at the
rates applicable to U.S. individuals or corporations, without regard to
whether such distribution is designated as a capital gain dividend. In
addition, the Company will be required to withhold tax equal to 35% of the
amount of such distribution to the extent it constitutes USRPI Capital Gains.
Such distribution may also be subject to the 30% branch profits tax (unless
reduced by treaty) in the case of a Non-U.S. Shareholder that is a foreign
corporation.
 
  Non-Dividend Distributions. Any distributions by the Company that exceed
both current and accumulated earnings and profits of the Company will not be
taxed as either ordinary dividends or capital gain dividends. See "Federal
Income Tax Considerations--Taxation of Shareholders--Taxation of Taxable
Domestic Shareholders." However, if it cannot be determined at the time a
distribution is made whether or not such distribution will be in excess of
current and accumulated earnings and profits, the distribution will be subject
to withholding. Should this occur, the Non-U.S. Shareholder may seek a refund
of overwithholding from the Service once it is subsequently determined that
such distribution was, in fact, in excess of current and accumulated earnings
and profits of the Company.
 
DISPOSITIONS OF SHARES OF BENEFICIAL INTEREST
 
  Unless the shares of beneficial interest constitute USRPIs, a sale or
exchange of shares of beneficial interest by a Non-U.S. Shareholder generally
will not be subject to U.S. taxation under FIRPTA. The shares of beneficial
interest will not constitute USRPIs if the Company is a "domestically
controlled REIT." A domestically
 
                                      20
<PAGE>
 
controlled REIT is a REIT in which, at all times during a specified testing
period, less than 50% in value of its shares is held directly or indirectly by
Non-U.S. Shareholders. It is currently anticipated that the Company will be a
domestically controlled REIT and, therefore, that the sale of shares of
beneficial interest will not be subject to taxation under FIRPTA. No assurance
can be given that the Company will continue to be a domestically controlled
REIT.
 
  If the Company does not constitute a domestically controlled REIT, a Non-
U.S. Shareholder's sale or exchange of shares of beneficial interest generally
will still not be subject to tax under FIRPTA as a sale of USRPIs provided
that (i) the Company's shares of beneficial interest are "regularly traded"
(as defined by applicable Treasury regulations) on an established securities
market (e.g., the NYSE, on which the Common Shares are listed) and (ii) the
selling Non-U.S. Shareholder held 5% or less of the Company's outstanding
shares of beneficial interest at all times during a specified testing period.
 
  If gain on the sale or exchange of shares of beneficial interest were
subject to taxation under FIRPTA, the Non-U.S. Shareholder would be subject to
U.S. income tax at the rates applicable to U.S. individuals or corporations,
and the purchaser of shares of beneficial interest could be required to
withhold 10% of the purchase price and remit such amount to the Service. The
branch profits tax would not apply to such sales or exchanges.
 
  Capital gains not subject to FIRPTA will nonetheless be taxable in the
United States to a Non-U.S. Shareholder in two cases: (i) if the Non-U.S.
Shareholder's investment in shares of beneficial interest is effectively
connected with a U.S. trade or business conducted by such Non-U.S.
Shareholder, the Non-U.S. Shareholder will be subject to the same treatment as
U.S. shareholders with respect to such gain or (ii) if the Non-U.S.
Shareholder is a nonresident alien individual who was present in the United
States for 183 days or more during the taxable year and has a "tax home" in
the United States, the nonresident alien individual will be subject to 30% tax
on the individual's capital gain (unless reduced or eliminated by treaty).
 
FEDERAL ESTATE TAX
 
  Shares of beneficial interest owned or treated as owned by an individual who
is not a citizen or "resident" (as specifically defined for U.S. Federal
estate tax purposes) of the United States at the time of death will be
includable in the individual's gross estate for U.S. Federal estate tax
purposes, unless an applicable estate tax treaty provides otherwise. Such
individual's estate may be subject to U.S. Federal estate tax on the property
includable in the estate for U.S. Federal estate tax purposes.
 
INFORMATION REPORTING AND BACKUP WITHHOLDING
 
  The Company must report annually to the Service 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.
 
  U.S. backup withholding (which generally is imposed at the rate of 31% on
certain payments to persons that fail to furnish the information required
under the U.S. information reporting requirements) and information reporting
will generally not apply to dividends (including any capital gain dividends)
paid on shares of beneficial interest to a Non-U.S. Shareholder at an address
outside the United States. The proposed Treasury regulations referred to under
"--Distributions from the Company--Ordinary Dividends," in general, would
similarly require a Non-U.S Shareholder to provide the form W-8 previously
referred to in order for dividends paid after December 31, 1997 to be exempt
from backup withholding and information reporting.
 
  The payment of the proceeds from the disposition of shares of beneficial
interest to or through a U.S. office of a broker will be subject to
information reporting and backup withholding unless the owner, under penalties
of
 
                                      21
<PAGE>
 
perjury, certifies, among other things, its status as a Non-U.S. Shareholder,
or otherwise establishes an exemption. The payment of the proceeds from the
disposition of shares of beneficial interest to or through a non-U.S. office
of a non-U.S. broker generally will not be subject to backup withholding and
information reporting, except as noted below. In the case of a payment of
proceeds from the disposition of shares of beneficial interest to or through a
non-U.S. office of a broker which is (i) a U.S. person, (ii) a "controlled
foreign corporation" for U.S. Federal income tax purposes or (iii) a foreign
person 50% or more of whose gross income for certain periods is derived from a
U.S. trade or business, information reporting (but not backup withholding)
will apply unless the broker has documentary evidence in its files that the
holder is a Non-U.S. Shareholder (and the broker has no actual knowledge to
the contrary) and certain other conditions are met, or the holder otherwise
establishes an exemption. Under proposed Treasury regulations, a payment of
the proceeds from the disposition of shares of beneficial interest to or
through such broker will be subject to backup withholding if such broker has
actual knowledge that the holder is a U.S. person.
 
  Backup withholding is not an additional tax. Any amounts withheld under the
backup withholding rules will be refunded or credited against the Non-U.S.
Shareholder's U.S. Federal income tax liability, provided that required
information is furnished to the Service.
 
  These backup withholding and information reporting rules are currently under
review by the Treasury Department, and their application to shares of
beneficial interest is subject to change.
 
                             PLAN OF DISTRIBUTION
 
  The Company may sell the Offered Securities to one or more underwriters for
public offering and sale by them or may sell the Offered Securities to
investors directly or through agents. Direct sales to investors may be
accomplished through subscription offerings or through Shareholder Purchase
Rights distributed to the Company's shareholders. See "Description of
Shareholder Purchase Rights." In connection with subscription offerings or the
distribution of Shareholder Purchase Rights to shareholders, if all of the
underlying Offered Securities are not subscribed for, the Company may sell
such unsubscribed Offered Securities to third parties directly or through
underwriters or agents and, in addition, whether or not all of the underlying
Offered Securities are subscribed for, the Company may concurrently offer
additional Offered Securities to third parties directly or through
underwriters or agents. Any such underwriter or agent involved in the offer
and sale of the Offered Securities will be named in the applicable Prospectus
Supplement.
 
  The distribution of the Offered Securities may be effected from time to time
in one or more transactions at a fixed price or prices, which may be changed,
or at prices related to the prevailing market prices at the time of sale or at
negotiated prices (any of which may represent a discount from the prevailing
market prices). The Company also may, from time to time, authorize
underwriters acting as the Company's agents to offer and sell the Offered
Securities upon the terms and conditions as are set forth in the applicable
Prospectus Supplement. In connection with the sale of Offered Securities,
underwriters may be deemed to have received compensation from the Company in
the form of underwriting discounts or commissions and may also receive
commissions from purchasers of Offered Securities for whom they may act as
agent. Underwriters may sell Offered Securities to or through dealers, and
such dealers may receive compensation in the form of discounts, concessions or
commissions from the underwriters and/or commissions from the purchasers for
whom they may act as agent.
 
  Any underwriting compensation paid by the Company to underwriters or agents
in connection with the offering of Offered Securities, and any discounts,
concessions or commissions allowed by underwriters to participating dealers,
will be set forth in the applicable Prospectus Supplement. Underwriters,
dealers and agents participating in the distribution of the Offered Securities
may be deemed to be underwriters, and any discounts and commissions received
by them and any profit realized by them on resale of the Offered Securities
may be deemed to be underwriting discounts and commissions, under the
Securities Act. Underwriters, dealers and agents may be entitled, under
agreements entered into with the Company, to indemnification against and
contribution toward certain civil liabilities, including liabilities under the
Securities Act.
 
 
                                      22
<PAGE>
 
  If so indicated in the applicable Prospectus Supplement, the Company will
authorize dealers acting as the Company's agents to solicit offers by certain
institutions to purchase Offered Securities from the Company at the public
offering price set forth in such Prospectus Supplement pursuant to Delayed
Delivery Contracts ("Contracts") providing for payment and delivery on the
date or dates stated in such Prospectus Supplement. Each Contract will be for
an amount not less than, and the aggregate principal amount of Offered
Securities sold pursuant to Contracts shall be not less nor more than, the
respective amounts stated in the applicable Prospectus Supplement.
Institutions with whom Contracts, when authorized, may be made include
commercial and savings banks, insurance companies, pension funds, investment
companies, educational and charitable institutions, and other institutions but
will in all cases be subject to the approval of the Company. Contracts will
not be subject to any conditions except (i) the purchase by an institution of
the Offered Securities covered by its Contracts shall not at the time of
delivery be prohibited under the laws of any jurisdiction in the United States
to which such institution is subject; and (ii) if the Offered Securities are
being sold to underwriters, the Company shall have sold to such underwriters
the total principal amount of the Offered Securities less the principal amount
thereof covered by Contracts.
 
  Certain of the underwriters and their affiliates may be customers of, engage
in transactions with and perform services for the Company and its subsidiaries
in the ordinary course of business.
