INFORMATION APPEARING ELSEWHERE IN THIS PROSPECTUS SUPPLEMENT OR THE
ACCOMPANYING PROSPECTUS OR INCORPORATED HEREIN OR THEREIN BY REFERENCE.
CAPITALIZED TERMS USED IN THIS PROSPECTUS SUPPLEMENT SUMMARY HAVE THE MEANINGS
SET FORTH ELSEWHERE IN THIS PROSPECTUS SUPPLEMENT OR THE ACCOMPANYING
PROSPECTUS. THE OFFERING OF THE 7.125% NOTES DUE NOVEMBER 1, 2003 (THE "NOTES"),
IS HEREIN REFERRED TO AS THE "OFFERING." ALL REFERENCES TO THE "PARTNERSHIP"
INCLUDE SUSA PARTNERSHIP, L.P., THOSE ENTITIES OWNED OR CONTROLLED BY SUSA
PARTNERSHIP, L.P. AND PREDECESSORS OF SUSA PARTNERSHIP, L.P., UNLESS THE CONTEXT
INDICATES OTHERWISE.
 
                                THE PARTNERSHIP
 
    The Partnership is engaged in the business of owning, managing, acquiring,
developing and franchising self-storage facilities. At September 30, 1996, the
Partnership owned 215 facilities containing 14.5 million net rentable square
feet in 29 states and the District of Columbia and managed for others 19
facilities containing an additional 1.1 million net rentable square feet, making
it the fourth largest operator of self-storage facilities in the United States.
The facilities are located in or near major metropolitan areas, operate under
the Storage USA-Registered Trademark- name, and offer low-cost, easily
accessible and enclosed storage space for personal and business use. Average
physical and economic occupancy for the facilities owned by the Partnership at
September 30, 1996, were 89% and 83%, respectively. Average weighted annual rent
per square foot for these facilities was $9.46.
 
    The Partnership is a fully integrated organization that has expertise in
acquisition, development, construction and management of self-storage facilities
and has approximately 840 employees. Its sole general partner is Storage USA,
Inc. (the "Company"), which is a publicly-held, self-managed and self-advised
real estate investment trust ("REIT"). The Company conducts all of its
activities through the Partnership and its subsidiaries, and at September 30,
1996, it owned a 95% interest in the Partnership.
 
    The Partnership's primary business objectives are to increase its cash flow
from operations and the value of the Partnership's facilities. The Partnership
plans to achieve these objectives through the strategies discussed below,
including improving the operations of its facilities and selectively expanding
its portfolio of facilities through acquisition and development. The Partnership
believes that it is distinguishable from most of its competitors by its access
to capital markets, the management information systems it has developed, the
skilled personnel it has gathered and trained for managing self-storage
facilities, and its expertise in acquiring and developing self-storage
facilities in diverse locales with potential for increased occupancy and rental
rates.
 
SELF-STORAGE FACILITIES
 
    The Partnership's self-storage facilities offer customers fully-enclosed
units, which are for their exclusive use and to which they control access by
furnishing their own locks. The facilities generally contain 400 to 1,000 units
varying in size from 25 to 400 square feet. The majority of the Partnership's
tenants are individuals, ranging from high-income homeowners to college
students, who typically store furniture, appliances and other household and
personal items. Commercial users range from sales representatives and
distributors storing inventory to small businesses that typically store
equipment, records and seasonal items. The facilities generally have a diverse
tenant base of 500-600 tenants, with no single tenant occupying more than one to
two percent of the net rentable square feet of a facility.
 
    The Partnership's self-storage facilities are located near major business
and residential areas, and generally are clearly visible and easily accessible
from major traffic arteries. They generally are protected by computer-controlled
access gates, door alarm systems and video cameras. These facilities typically
are constructed of one-story 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 and to protect items from damage. Sites have
wide drive aisles to accommodate most vehicles. The Partnership's facilities are
designed to be aesthetically pleasing, are kept clean and in good repair by
friendly, trained managers, and are open for service during hours and on days
convenient to tenants and prospective tenants. At most of the facilities, a
property manager lives in an apartment located on site. Climate-controlled space
 
                                      S-3
<PAGE>
is offered in many of the facilities for storing items that are sensitive to
extreme humidity or temperature. Some of the facilities provide paved secure
storage areas for recreational vehicles, boats and commercial vehicles. All
facilities offer reception of deliveries for commercial customers.
 
INTERNAL GROWTH STRATEGY
 
    The Partnership's internal growth strategy is to pursue an active leasing
policy (which includes aggressively marketing available space and renewing
existing leases at higher rents per square foot) and to draw upon management's
industry expertise to satisfy its customers. As a result of its internal growth
strategy, the Partnership has historically received premium rents, while
achieving high occupancy levels and increasing profitability. By implementing
this strategy for the 96 facilities owned by the Partnership since December 31,
1994, the Partnership, for the first six months of 1996, increased revenue and
net operating income by 7.6% and 6.1%, respectively, over revenue and net
operating income achieved by the Partnership in the same period of the prior
year. See "The Partnership -- Internal Growth Strategy."
 
EXTERNAL GROWTH STRATEGY
 
    The Partnership's external growth strategy is designed to increase the
number of facilities owned by the Partnership either by acquiring suitably
located, under-performing facilities that offer upside potential due to low
occupancy rates or non-premium pricing, or by developing and constructing new
self-storage facilities in favorable markets. In pursuing acquisition
opportunities, the Partnership seeks to add facilities in those metropolitan
areas in which the Partnership operates and selectively to enter new markets
that have desirable characteristics such as a growing population and a
concentration of multifamily dwellings. With respect to its development effort,
the Partnership's current strategy is to develop facilities in those markets in
which it currently operates. The Partnership intends to acquire or develop
facilities that are near residential areas, clearly visible to consumer traffic,
easily accessible for entrance and exit and attractively designed. See "The
Partnership -- External Growth Strategy."
 
    Since the closing of the Company's initial public offering on March 23, 1994
(the "IPO"), the Partnership has purchased 170 self-storage facilities
containing 11.6 million net rentable square feet for an aggregate purchase price
of approximately $563.8 million. The Partnership has also completed construction
of two new facilities and expansions to three facilities, collectively
containing 0.2 million square feet, since the IPO.
 
CAPITAL STRATEGY
 
    The Partnership and the Company intend to maintain a conservative capital
structure designed to enhance access to capital and to facilitate earnings
growth. Since the IPO, the Company has completed two public follow-on offerings
of its Common Stock raising total net proceeds of $253.4 million. The Company
has most recently completed a private placement of $220.0 million of its Common
Stock with Security Capital U.S. Realty ("USRealty"), an affiliate of Security
Capital Group. This investment was part of a strategic alliance that permits
USRealty to participate in future equity financings by the Company as necessary
to maintain its ownership interest in the Company. See "--Recent Developments --
Strategic Alliance with Security Capital U.S. Realty." The Company contributes
the proceeds of sales of its Common Stock to the Partnership in exchange for
additional units of interest in the Partnership ("Units"). In addition, since
the IPO, the Partnership has exchanged 1.2 million Units in consideration for
the acquisition of 27 self-storage facilities valued at $34.5 million.
 
    The Partnership has available $105.0 million in unsecured revolving lines of
credit with a group of commercial banks, under which it had borrowed $66.1
million at September 30, 1996. At September 30, 1996, the Partnership also had
mortgage loans outstanding of $18.0 million that were secured by six properties.
The debt policy of the Company and the Partnership, which is subject to change
at the discretion of the Company's Board of Directors, is to limit total
indebtedness to the lesser of 50% of total assets at cost or that amount that
will sustain a minimum debt service coverage ratio of 3:1. On a pro forma basis,
after giving effect to the completion of the Offering, as of September 30, 1996,
the total indebtedness of the Partnership would have been 15.7% of total assets
at cost and its debt service coverage ratio for the six months ended June 30,
1996, would have been 7.2:1. The Partnership believes
 
                                      S-4
<PAGE>
that its debt policy, the Company's success in raising equity capital, its
preference for unsecured debt, and its ability to purchase self-storage
facilities in exchange for Units all demonstrate the commitment of the Company
and the Partnership to maintain a conservative but flexible capital structure
that should permit continued access to the capital markets on favorable terms.

    At September 30, 1996, average physical and economic occupancy of the 215
facilities owned by the Partnership were 89% and 83%, respectively, with an
average rent per square foot of $9.46. For the 146 facilities owned by the
Partnership since September 30, 1995, average physical and economic occupancy at
September 30, 1996 were 89% and 83%, respectively, compared to 90% and 84%,
respectively, at September 30, 1995. For those same 146 facilities, average rent
per square foot increased from $8.98 at September 30, 1995 to $9.60 at September
30, 1996.
 
STRATEGIC ALLIANCE WITH SECURITY CAPITAL U.S. REALTY
 
    On March 1, 1996, the Company entered into a Stock Purchase Agreement with
USRealty. Under the Stock Purchase Agreement, USRealty invested $60.0 million on
July 8, 1996 and invested $99.0 million on September 30, 1996, to complete its
purchase from the Company of 7,028,754 shares of the Company's Common Stock for
an aggregate direct investment of $220.0 million. USRealty has purchased an
additional 1,520,800 shares of the Company's Common Stock on the open market and
owned a total of 8,549,554 shares, or 34.7%, of the Company's outstanding Common
Stock as of September 30, 1996. The Company's Amended Charter permits USRealty
and its affiliates to own up to 37.5% of the Company's Common Stock. Pursuant to
the terms of a Strategic Alliance Agreement entered into by the Company with
USRealty in connection with the Stock Purchase Agreement, effective November 4,
1996, USRealty placed two of its nominees on the Company's Board of Directors,
William D. Sanders, Chairman of the Board and Chief Executive Officer of
Security Capital Group, and J. Marshall Peck, Managing Director of Security
Capital Investment Research Incorporated. USRealty's investment in the Company
is subject to additional terms and limitations under the Strategic Alliance
Agreement and a Registration Rights Agreement.
 
    The Partnership believes that the alliance with USRealty has provided it
with access to significant additional financial and strategic resources not
otherwise readily available to it, thereby enhancing its
 
                                      S-5
<PAGE>
short-term and long-term growth prospects and better positioning it to
capitalize on opportunities as the REIT industry matures. The Partnership also
expects that it will benefit significantly from its affiliation with USRealty
and access to USRealty's market knowledge, operating experience and research
capabilities.

in 11 states and containing 1.6 million net rentable square feet for an

the Partnership had contracted to acquire 8 additional facilities totaling 0.5
million net rentable square feet, and has under construction or in development
1.3 million net rentable square feet contained in 15 new facilities and in
expansions to 15 existing facilities.

(1) See "SUSA Partnership, L.P. Pro Forma Financial Information."
(2) Funds from Operations ("FFO") means net income, computed in accordance with
    generally accepted accounting principles ("GAAP"), excluding gains (losses)
    from debt restructuring and sales of property, plus depreciation and
    amortization and after adjustments for unconsolidated partnerships and joint
    ventures. Management generally considers FFO to be a useful financial
    performance measurement of an equity REIT because, together with net income
    and cash flows, FFO provides investors with an additional basis to evaluate
    the ability of a REIT to incur and service debt and to fund acquisitions and
    other capital expenditures. FFO does not represent net income or cash flows
    from operating, investing or financing activities as defined by GAAP. It
    should not be considered as an alternative to net income as an indicator of
    the Partnership's operating performance or to cash flows as a measure of
    liquidity. FFO does not measure whether cash flow is sufficient to fund all
    cash needs including principal amortization, capital improvements and
    distributions to shareholders. Further, funds from operations statistics as
    disclosed by other REITs may not be comparable to the Partnership's
    calculation of FFO.
(3) Reflects the Partnership's cash flows and pro forma cash flows from
    operating, investing and financing activities. Pro forma cash flows from
    operating activities represents net income plus income allocable to minority
    interest, depreciation of self-storage facilities and amortization of
    deferred expenses, line of credit fees and the cost of an interest rate
    "lock." There are no pro forma adjustments for changes in working capital
    items. Pro forma cash used in investing activities reflects the acquisition
    of the 117 facilities acquired during 1995 and 1996 for an aggregate
    purchase price of $414 million. Pro forma cash used in financing activities
    includes the receipt of $220 million in proceeds from USRealty's purchase of
    7,028,754 shares of Common Stock of the Company, the receipt of $107.6
    million in proceeds from the public offering of Common Stock completed on
    June 7, 1995, and the repayment of $147 million outstanding under the
    Partnership's credit facilities. This unaudited pro forma cash flow data is
    not necessarily indicative of what actual cash flows would have been
    assuming the transactions had been completed as of the beginning of each of
    the periods presented, nor does it purport to represent cash flows from
    operating, investing and financing activities for future periods.
(4) EBIDA means earnings before interest expense, depreciation, amortization and
    minority interest. EBIDA is computed as income from operations before
    minority interest and extraordinary items plus interest expense,
    depreciation and amortization. The Partnership believes that in addition to
    cash flows and net income, EBIDA is a useful financial performance
    measurement for assessing the operating performance of an equity REIT
    because, together with net income and cash flows, EBIDA provides investors
    with an additional basis to evaluate the ability of a REIT to incur and
    service debt and to fund acquisitions and other capital expenditures. To
    evaluate EBIDA and the trends it depicts, the components of EBIDA, such as
    rental revenues, rental expenses, real estate taxes and general and
    administrative expenses, should be considered. See "Management's Discussion
    and Analysis of Financial Condition and Results of Operations" included
    herein and included or incorporated by reference in the accompanying
    Prospectus. Excluded from EBIDA are financing costs such as interest as well
    as depreciation and amortization, each of which can significantly affect a
    REIT's results of operations and liquidity and should be considered in
    evaluating a REIT's operating performance. Further, EBIDA does not represent
    net income or cash flows from operating, financing and investing activities
    as defined by GAAP and does not necessarily indicate that cash flows will be
    sufficient to fund cash needs. It should not be considered as an alternative
    to net income as an indicator of the Partnership's operating performance or
    to cash flows as a measure of liquidity.
(5) The ratio of earnings to fixed charges is computed as income from operations
    before extraordinary items plus fixed charges (excluding capitalized
    interest) divided by fixed charges. Fixed charges consist of interest costs
    including amortization of debt discount and deferred financing fees, whether
    capitalized or expensed and the interest component of rental expense.
(6) The ratio of FFO before fixed charges to fixed charges is calculated as FFO
    plus fixed charges (consisting primarily of interest expense), excluding
    amortization of debt discount and deferred financing fees divided by fixed
    charges. The Partnership believes that in addition to the ratio of earnings
    to fixed charges, this ratio provides a useful measure of a REIT's ability
    to service its debt because of the exclusion of non-cash items such as
    depreciation and amortization from the definition of FFO. This ratio differs
    from a GAAP-based ratio of earnings to fixed charges and should not be
    considered as an alternative to that ratio. Further, funds from operations
    statistics as disclosed by other REITs may not be comparable to the
    Partnership's calculation of FFO.

OF DEBT SECURITIES" IN THE ACCOMPANYING PROSPECTUS.
 
<TABLE>
<S>                            <C>
SECURITIES OFFERED...........  $100,000,000 aggregate principal amount of Notes.
 
MATURITY.....................  The Notes mature on November 1, 2003.
 
INTEREST PAYMENT DATES.......  Interest on the Notes is payable semi-annually on May 1 and
                               November 1 of each year, commencing May 1, 1997.
 
OPTIONAL REDEMPTION..........  The Notes are redeemable at any time at the option of the
                               Partnership, in whole or in part, at a redemption price
                               equal to the sum of (i) the principal amount of the Notes
                               being redeemed plus accrued interest to the redemption date
                               and (ii) the Make-Whole Amount, if any. See "Description of
                               Notes -- Optional Redemption."
 
RANKING......................  The Notes are unsecured obligations of the Partnership and
                               will rank PARI PASSU with each other and with all other
                               unsecured and unsubordinated indebtedness of the Partnership
                               and will be effectively subordinated to all secured debt of
                               the Partnership. As of September 30, 1996, the Partnership
                               had outstanding $66.1 million of unsecured, unsubordinated
                               indebtedness and $18.0 million of secured indebtedness. On a
                               pro forma basis as of September 30, 1996, after giving
                               effect to the completion of the Offering and application of
                               the net proceeds from the Offering as described in "Use of
                               Proceeds," the Partnership would have had outstanding $100.0
                               million of unsecured, unsubordinated indebtedness, $18.0
                               million of secured indebtedness and $735.5 million in
                               unencumbered assets.
 
USE OF PROCEEDS..............  The net proceeds to the Partnership from the Offering will
                               be used to repay outstanding debt incurred in connection
                               with the acquisition of self-storage facilities and for
                               general corporate purposes. See "Use of Proceeds."
 
LIMITATIONS ON INCURRENCE OF
 INDEBTEDNESS................  The Notes contain various covenants, including the
                               following:
 
                               (1) The Partnership will not incur any Indebtedness, if,
                               after giving effect thereto, the aggregate principal amount
                               of all outstanding Indebtedness of the Partnership is
                               greater than 60% of the sum of (i) Total Assets as of the
                               end of the Partnership's fiscal quarter ended immediately
                               prior to the incurrence of such Indebtedness and (ii) the
                               increase in Total Assets since the end of such quarter,
                               including any increase in Total Assets resulting from the

                                THE PARTNERSHIP
 
    The Partnership is engaged in the business of owning, managing, acquiring,
developing and franchising self-storage facilities. At September 30, 1996, the
Partnership owned 215 facilities containing 14.5 million net rentable square
feet in 29 states and the District of Columbia and managed for others 19
facilities containing an additional 1.1 million net rentable square feet, making
it the fourth largest operator of self-storage facilities in the United States.
The facilities are located in or near major metropolitan areas, operate under
the Storage USA-Registered Trademark- name, and offer low-cost, easily
accessible and enclosed storage space for personal and business use. Average
physical and economic occupancy for the facilities owned by the Partnership at
September 30, 1996, were 89% and 83%, respectively. Physical occupancy is
computed by dividing the total net rentable square feet occupied as of the date
computed by the total net rentable square feet for the facilities in a
particular location. Economic occupancy is computed by dividing the expected
income by the gross potential income. Gross potential income is defined as the
sum of all units available to rent multiplied by the market rental rate
applicable to those units as of the date computed. Expected income is defined as
the sum of all units rented as of the date computed, multiplied by the rental
rate per the existing leases applicable to those units as of the date computed.
Rent per square foot for the facilities owned by the Partnership at September
30, 1996, was $9.46. Rent per square foot is the annualized result obtained by
dividing gross potential income by total net rentable square feet available on a
given date.
 
    The Partnership is a fully integrated organization that has expertise in
acquisition, development, construction and management of self-storage facilities
and has approximately 840 employees. Its sole general partner is Storage USA,
Inc. (the "Company"), which is a publicly-held, self-managed and self-advised
real estate investment trust ("REIT"). The Company conducts all of its
activities through the Partnership and its subsidiaries, and at September 30,
1996, it owned a 95% interest in the Partnership.
 
    The Partnership's primary business objectives are to increase its cash flow
from operations and the value of the Partnership's facilities. The Partnership
plans to achieve these objectives through the strategies discussed below,
including improving the operations of its facilities and selectively expanding
its portfolio of facilities through acquisition and development. The Partnership
believes that it is distinguishable from most of its competitors by its access
to capital markets, the management information systems it has developed, the
skilled personnel it has gathered and trained for managing self-storage
facilities, and its expertise in acquiring and developing self-storage
facilities in diverse locales with potential for increased occupancy and rental
rates.
 
SELF-STORAGE FACILITIES
 
    The Partnership's self-storage facilities offer customers fully-enclosed
units, which are for their exclusive use and to which they control access by
furnishing their own locks. The facilities generally contain 400 to 1,000 units
varying in size from 25 to 400 square feet. The majority of the Partnership's
tenants are individuals, ranging from high-income homeowners to college
students, who typically store furniture, appliances and other household and
personal items. Commercial users range from sales representatives and
distributors storing inventory to small businesses that typically store
equipment, records and seasonal items. The facilities generally have a diverse
tenant base of 500-600 tenants, with no single tenant occupying more than one to
two percent of the net rentable square feet of a facility.
 
    The Partnership's self-storage facilities are located near major business
and residential areas, and generally are clearly visible and easily accessible
from major traffic arteries. They are generally protected by computer-controlled
access gates, door alarm systems and video cameras. These facilities are
typically constructed of one-story 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 and to protect items from damage. Sites have
wide drive aisles to accommodate most vehicles. The Partnership's facilities are
designed to be aesthetically pleasing, are kept clean and in good repair by
friendly, trained managers, and are open for service during hours and on days
convenient to tenants and prospective tenants. At most of the facilities, a
property manager lives in an apartment located on site. Climate-controlled
 
                                      S-11

space is offered in many of the facilities for storing items that are sensitive
to extreme humidity or temperature. Some of the facilities provide paved secure
storage areas for recreational vehicles, boats and commercial vehicles. All
facilities offer reception of deliveries for commercial customers.
 
    The following table sets forth the location, total rentable square footage
and the physical and economic occupancy rates of the Partnership's self-storage
facilities as of September 30, 1996.

</TABLE>
 
INTERNAL GROWTH STRATEGY
 
    The Partnership's internal growth strategy is to pursue an active leasing
policy (which includes aggressively marketing available space and renewing
existing leases at higher rents per square foot) and to draw upon management's
industry expertise to satisfy its customers. As a result of its internal growth
strategy, the Partnership has historically received premium rents, while
achieving high occupancy levels and increasing profitability. By implementing
this strategy for the 96 facilities owned by the Partnership since December 31,
1994, the Partnership, for the first six months of 1996, increased revenue and
net operating income by 7.6% and 6.1%, respectively, over revenue and net
operating income achieved by the Partnership in the same period of the prior
year.
 
    -AGGRESSIVE LEASING -- The Partnership seeks to increase its revenues by
     increasing and maintaining the occupancy in its facilities through the use
     of sales and marketing programs that are customized for each location by
     facility managers who have substantial authority and effective incentives.
     The facility managers are trained to market both phone-in and walk-in
     prospective tenants. Emphasis is placed on conversion from the initial
     telephone call to an on-site visit and from the on-site visit to a rental.
 
                                      S-12
<PAGE>
    -REGULARLY SCHEDULED RENT INCREASES -- The Partnership has historically
     increased rents in all of its facilities at least once a year regardless of
     the occupancy level. As a facility nears 100% occupancy, the Partnership
     typically increases rents more frequently.
 
    -GUARANTEED CUSTOMER SATISFACTION -- The Partnership requires its employees
     to be customer satisfaction-oriented. In the Partnership's "Total Storage
     Satisfaction Guaranteed" program, the facility managers have authority to
     resolve most customer problems through rent rebates or cash reimbursements
     without obtaining prior approval from Partnership management.
 
    -TRAINED FACILITY MANAGERS -- The Partnership carefully selects and
     thoroughly trains managers of its self-storage facilities. To hire
     outgoing, personable, sales-oriented people capable of implementing these
     programs, the Partnership uses personality profiles and personal interviews
     to screen applicants during the recruiting process. Training programs
     feature facility operations and marketing manuals, sales and marketing
     programs, telephone communication, and computer and daily facility
     operations (unit rental, retail sales, facility maintenance, security
     systems and financial duties). The Partnership's formal training programs
     are followed by on-the-job training (supervised by a regional manager) and
     a three-step, self-administered certification program. The Partnership
     conducts monthly telephone surveys in which "mystery shoppers" hired by the
     Partnership call each facility posing as prospective customers. These
     telephone calls are recorded and graded by management for policy compliance
     and sales skills.
 
    -INTEGRATED MANAGEMENT INFORMATION SYSTEMS -- To maintain appropriate
     controls and enhance operational efficiencies, the Partnership has
     installed at each facility computer systems with comprehensive facilities
     management software. Weekly operating results are transmitted
     electronically from each of these facilities to the Partnership's
     headquarters. These systems allow the Partnership to monitor closely
     manager performance and market response to the Partnership's rental
     structure.
 
EXTERNAL GROWTH STRATEGY
 
    The Partnership's external growth strategy is designed to increase the
number of facilities owned by the Partnership either by acquiring suitably
located, under-performing facilities that offer upside potential due to low
occupancy rates or non-premium pricing, or by developing and constructing new
self-storage facilities in favorable markets. In pursuing acquisition
opportunities, the Partnership seeks to add facilities in those metropolitan
areas in which the Partnership operates and selectively to enter new markets
that have desirable characteristics such as a growing population and a
concentration of multifamily dwellings. With respect to its development effort,
the Partnership's current strategy is to develop facilities in those markets in
which it currently operates. The Partnership intends to acquire or develop
facilities that are near residential areas, clearly visible to consumer traffic,
easily accessible for entrance and exit and attractively designed.
 
  ACQUISITIONS
 
    Since the IPO, the Partnership has purchased 170 self-storage facilities
containing 11.6 million net rentable square feet for an aggregate purchase price
of approximately $563.8 million. Management believes that there are several
factors that favor its acquisition policy:
 
    -FRAGMENTED INDUSTRY OWNERSHIP -- The Partnership believes that there are
     approximately 25,000 self-storage facilities in the United States with
     approximately 906 million net rentable square feet. At September 30, 1996,
     the 10 largest operators of self-storage facilities managed approximately
     2,900 or 12% of all facilities. Management believes this fragmented
     ownership offers opportunities for acquisitions, including opportunities
     resulting from the necessity of sale by some smaller operators who cannot
     obtain refinancing, the desire of some smaller operators to sell their
     facilities to obtain retirement funds or to seek alternative investments,
     and the inability of other smaller operators to obtain funds with which to
     compete for acquisitions as timely and inexpensively as the Partnership.
 
                                      S-13
<PAGE>
    -OPERATING EFFICIENCIES -- The Partnership believes that a significant
     percentage of self-storage properties are owned by smaller operators which
     historically have been operated less efficiently than the Partnership's
     facilities. Management believes it has developed an expertise in improving
     the performance of such properties.
 
    -DEMAND FOR TAX DEFERRAL -- In several of its acquisitions, the Partnership
     has financed a portion of the sales price through the issuance of Units,
     permitting the sellers to at least partially defer taxation of capital
     gains. The Partnership believes that its ability to offer Units as a form
     of consideration is a key element in its ability to successfully negotiate
     with sellers of self-storage facilities. Since the IPO, the Partnership has
     exchanged 1.2 million Units valued at $34.5 million in consideration for
     the acquisition of 27 self-storage facilities.
 
    -PROPERTY ASSIMILATION -- The Partnership's integrated management
     information systems allow it to quickly and efficiently assimilate its
     acquisition targets. All of the Partnership's facilities are electronically
     linked to a central computer system, which allows management to control an
     increased number of facilities with minimal additional human resources.
     Management expects the data systems, together with its track record of
     managing or developing facilities in new areas of the country, to assist in
     integrating future facilities into the Partnership. Commonly, the
     Partnership is able to retrain existing managers of acquired facilities and
     rapidly realize operating improvements.
 
  DEVELOPMENT
 
    Management believes that there are factors that favor its facilities
development strategy. These factors include:
 
    -DEVELOPMENT EXPERTISE -- The Partnership has recently taken advantage of
     its in-house development capability to selectively develop new facilities
     in areas where suitable acquisitions may not be available. The development
     activities consist primarily of additions to existing facilities and
     construction of new facilities. Since 1985, the Partnership and predecessor
     organizations have developed and constructed 21 facilities, 15 of which the
     Partnership owns. At September 30, 1996, the Partnership had under
     construction or in development approximately 1.3 million net rentable
     square feet contained in 15 new facilities and in expansions to 15 existing
     facilities.
 
    -DEVELOPMENT CAPITAL -- The Partnership has a proven ability to access
     various forms of capital that differentiates it from most competitors,
     particularly since capital for the construction of new self-storage
     facilities (traditionally funded by savings and loan associations) has been
     less available in recent years.
 
CAPITAL STRATEGY
 
    The Partnership and the Company intend to maintain a conservative capital
structure designed to enhance access to capital and to facilitate earnings
growth. Since the IPO, the Company has completed two public follow-on offerings
of its Common Stock raising total net proceeds of $253.4 million. The Company
has most recently completed a private placement of $220.0 million of its Common
Stock with USRealty, an affiliate of Security Capital Group. This investment was
part of a strategic alliance that permits USRealty to participate in future
equity financings by the Company as necessary to maintain its ownership interest
in the Company. The Company contributes the proceeds of sales of its Common
Stock to the Partnership in exchange for additional Units. In addition, since
the IPO, the Partnership has exchanged 1.2 million Units in consideration for
the acquisition of 27 self-storage facilities valued at $34.5 million.
 
    The Partnership has available $105.0 million in unsecured revolving lines of
credit with a group of commercial banks, under which it had borrowed $66.1
million as of September 30, 1996. At September 30, 1996, the Partnership also
had mortgage loans outstanding of $18.0 million that were secured by six
properties. The policy of the Company and the Partnership, which is subject to
change at the discretion of the Company's Board of Directors, is to limit total
indebtedness to the lesser of 50% of total assets at cost or that amount that
will sustain a minimum debt service coverage ratio of 3:1. On a pro

forma basis, after giving effect to the completion of the Offering, as of
September 30, 1996, the total indebtedness of the Partnership would have been
15.7% of total assets at cost and its debt service coverage ratio for the six
months ended June 30, 1996, would have been 7.2:1. The Partnership believes that
this policy, the Company's success in raising equity capital, its preference for
unsecured debt and its ability to purchase self-storage facilities in exchange
for Units all demonstrate the commitment of the Partnership to maintain a
conservative but flexible capital structure that will permit continued access to
the capital markets on favorable terms.
 
STRATEGIC ALLIANCE WITH SECURITY CAPITAL U.S. REALTY
 
    On March 1, 1996, the Company entered into a Stock Purchase Agreement with
USRealty. Under the Stock Purchase Agreement, USRealty invested $60.0 million on
July 8, 1996 and invested $99.0 million on September 30, 1996, to complete its
purchase from the Company of 7,028,754 shares of the Company's Common Stock for
an aggregate direct investment of $220.0 million. USRealty has purchased an
additional 1,520,800 shares of the Company's Common Stock on the open market and
owned a total of 8,549,554 shares, or 34.7%, of the Company's outstanding Common
Stock as of September 30, 1996. The Company's Amended Charter permits USRealty
and its affiliates to own up to 37.5% of the Company's Common Stock. Pursuant to
the terms of a Strategic Alliance Agreement entered into by the Company with
USRealty in connection with the Stock Purchase Agreement, effective November 4,
1996, USRealty placed two of its nominees on the Company's Board of Directors,
William D. Sanders, Chairman of the Board and Chief Executive Officer of
Security Capital Group, and J. Marshall Peck, Managing Director of Security
Capital Investment Research Incorporated. USRealty's investment in the Company
is subject to additional limitations and terms under the Strategic Alliance
Agreement and a Registration Rights Agreement.
 
    The Partnership believes that the alliance with USRealty has provided it
with access to significant additional financial and strategic resources not
otherwise readily available to it, thereby enhancing its short-term and
long-term growth prospects and better positioning it to capitalize on
opportunities as the REIT industry matures. The Partnership also expects that it
will benefit significantly from its affiliation with USRealty and access to
USRealty's market knowledge, operating experience and research capabilities.
 
OTHER DEVELOPMENTS
 
    In June 1996, the Partnership formed Storage USA Franchise Corp. ("Franchise
Corp."), in which the Partnership has a 97.5% interest. Franchise Corp. offers
the Partnership's systems, expertise and a registered trademark to third parties
under a franchise program that the Partnership believes to be unique in the
self-storage industry. The Partnership formed Franchise Corp. to be a
non-capital intensive revenue source and does not anticipate that the franchise
program will have a material impact on its operating results in the near term.

    The net proceeds to the Partnership from the sale of the Notes offered
hereby are expected to be approximately $98.8 million. The Partnership will use
$66.5 million of the net proceeds from the Offering to retire debt incurred to
finance the acquisition of self-storage facilities under certain revolving
credit facilities with a current weighted average effective annual interest rate
of 6.8% and $2.5 million of the net proceeds from the Offering to settle an
interest rate hedge agreement. The remaining $29.8 million will be used for
general corporate purposes. Pending such uses, the net proceeds will be invested
in short-term marketable securities. An affiliate of First Chicago Capital
Markets, Inc., one of the Underwriters, is lender and agent under the $75
million line of credit and will receive a portion of the proceeds from the sale
of the Notes offered hereby. See "Underwriting."

(1) See "SUSA Partnership, L.P. Pro Forma Financial Information."
 
(2) FFO means net income, computed in accordance with GAAP, excluding gains
    (losses) from debt restructuring and sales of property, plus depreciation
    and amortization and after adjustments for unconsolidated partnerships and
    joint ventures. Management generally considers FFO to be a useful financial
    performance measurement of an equity REIT because, together with net income
    and cash flows, FFO provides investors with an additional basis to evaluate
    the ability of a REIT to incur and service debt and to fund acquisitions and
    other capital expenditures. FFO does not represent net income or cash flows
    from operating, investing or financing activities as defined by GAAP. It
    should not be considered as an alternative to net income as an indicator of
    the Partnership's operating performance or to cash flows as a measure of
    liquidity. FFO does not measure whether cash flow is sufficient to fund all
    cash needs including principal amortization, capital improvements and
    distributions to shareholders. Further, funds from operations statistics as
    disclosed by other REITs may not be comparable to the Partnership's
    calculation of FFO.
 
(3) Reflects the Partnership's cash flows and pro forma cash flows from
    operating, investing and financing activities. Pro forma cash flows from
    operating activities represents net income plus income allocable to minority
    interest, depreciation of self-storage facilities and amortization of
    deferred expenses, line of credit fees and the cost of an interest rate
    "lock." There are no pro forma adjustments for changes in working capital
    items. Pro forma cash used in investing activities reflects the acquisition
    of the 117 facilities acquired during 1995 and 1996 for an aggregate
    purchase price of $414 million. Pro forma cash used in financing activities
    includes the receipt of $220 million in proceeds from USRealty's purchase of
    7,028,754 shares of Common Stock of the Company, the receipt of $107.6
    million in proceeds from the public offering of Common Stock completed on
    June 7, 1995, and the repayment of $147 million outstanding under the
    Partnership's credit facilities. This unaudited pro forma cash flow data is
    not necessarily indicative of what actual cash flows would have been
    assuming the transactions had been completed as of the beginning of each of
    the periods presented, nor does it purport to represent cash flows from
    operating, investing and financing activities for future periods.
 
(4) EBIDA means earnings before interest expense, depreciation, amortization and
    minority interest. EBIDA is computed as income from operations before
    minority interest and extraordinary items plus interest expense,
    depreciation and amortization. The Partnership believes that in addition to
    cash flows and net income, EBIDA is a useful financial performance
    measurement for assessing the operating performance of an equity REIT
    because, together with net income and cash flows, EBIDA provides investors
    with an additional basis to evaluate the ability of a REIT to incur and
    service debt and to fund acquisitions and other capital expenditures. To
    evaluate EBIDA and the trends it depicts, the components of EBIDA, such as
    rental revenues, rental expenses, real estate taxes and general and
    administrative expenses, should be considered. See "Management's Discussion
    and Analysis of Financial Condition and Results of Operations" included
    herein and included or incorporated by reference in the accompanying
    Prospectus. Excluded from EBIDA are financing costs such as interest as well
    as depreciation and amortization, each of which can significantly affect a
    REIT's results of operations and liquidity and should be considered in
    evaluating a REIT's operating performance. Further, EBIDA does not represent
    net income or cash flows from operating, financing and investing activities
    as defined by GAAP and does not necessarily indicate that cash flows will be
    sufficient to fund cash needs. It should not be considered as an alternative
    to net income as an indicator of the Partnership's operating performance or
    to cash flows as a measure of liquidity.
 
(5) The ratio of earnings to fixed charges is computed as income from operations
    before extraordinary items plus fixed charges (excluding capitalized
    interest) divided by fixed charges. Fixed charges consist of interest costs
    including amortization of debt discount and deferred financing fees, whether
    capitalized or expensed and the interest component of rental expense.
 
(6) The ratio of FFO before fixed charges to fixed charges is calculated as FFO
    plus fixed charges (consisting primarily of interest expense), excluding
    amortization of debt discount and deferred financing fees divided by fixed
    charges. The Partnership believes that in addition to the ratio of earnings
    to fixed charges, this ratio provides a useful measure of a REIT's ability
    to service its debt because of the exclusion of non-cash items such as
    depreciation and amortization from the definition of FFO. This ratio differs
    from a GAAP-based ratio of earnings to fixed charges and should not be
    considered as an alternative to that ratio. Further, funds from operations
    statistics as disclosed by other REITs may not be comparable to the
    Partnership's calculation of FFO.

   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
               OPERATIONS FOR THE SIX MONTHS ENDED JUNE 30, 1996
 
    The following discussion and analysis of the consolidated financial
condition and results of operations of the Partnership for the six months ended
June 30, 1996, should be read in conjunction with the Consolidated Financial
Statements and Notes thereto and "Management's Discussion and Analysis of
Financial Condition and Results of Operations" included or incorporated by
reference in the Prospectus.
 
    Due to the substantial number of facilities acquired from June 30, 1995, to
June 30, 1996, management believes that it is meaningful and relevant in
understanding the present and ongoing operations of the Partnership to compare
certain information using occupancy, per square foot and pro forma data.
 
    The following are definitions of terms used throughout this discussion in
analyzing the Partnership's business. "Direct Property Operating Cost" is
defined as the costs incurred in the operation of a facility, such as utilities,
real estate taxes, and on-site personnel. "Indirect Property Operations Cost" is
defined as costs incurred in the management of all facilities, such as
accounting personnel and management level operations personnel. "Net Operating
Income" is defined as total property revenues less Direct Property Operating
Costs.
 
RESULTS OF OPERATIONS--SIX MONTHS ENDED JUNE 30, 1996, COMPARED TO SIX MONTHS
ENDED JUNE 30, 1995
 
    In the first six months of 1996, the Partnership reported growth in revenue,
Net Operating Income and net income, respectively, of $17.1 million, $11.0
million and $6.6 million over the same period of 1995. Management income for the
six months ended June 30, 1996, remained relatively consistent with 1995. Other
income, which reflects primarily sales of lock and packaging products and truck
rentals, increased primarily due to the increase in the number of properties
owned.
 
    Cost of property operations and maintenance was $12.1 million for the six
months ended June 30, 1996, representing a $4.2 million increase over the first
six months of 1995. Cost of property operations and maintenance was 26.5% of
revenues for the six months ended June 30, 1996, and 27.7% of revenues for the
six months ended June 30, 1995. The higher costs during 1995 were as a result of
the Partnership implementing its facility operating cost structure, along with
the addition of area and district managers. These costs preceded the revenue
growth related to the implementation of the Partnership's marketing and pricing
strategies.
 
    Tax expense increased from $1.9 million or 6.6% of revenues for the six
months ended June 30, 1995, to $3.7 million, or 8.2% of revenues, for the six
months ended June 30, 1996. This growth as a percentage of revenues reflects
both the impact of reassessments on the properties purchased during 1994 and
1995 and the increased state and franchise taxes as the Partnership moves into
new states and expands in current states. The majority of the real estate tax
increase is attributable to reassessments on acquisitions with the remainder
attributable to increased tax rates or reassessments on properties owned for a
full year.
 
    General and administrative expense increased from $1.1 million to $1.7
million for the first six months of 1996 from the comparable six months of 1995.
As a percentage of revenues, this category of expense fell from 3.9% for the six
months ended June 30, 1995, to 3.8% for the six months ended June 30, 1996. The
Partnership expects that the gross expense will grow as the Partnership expands
its administration, development and acquisition, management information systems,
and human resource departments, in connection with its ongoing growth strategy.
 
    Depreciation expense increased to $5.4 million for the six months ended June
30, 1996, from $3.4 million for the comparable period in 1995, reflecting the
increase in the number of facilities owned. The Partnership has acquired or
placed in service approximately $168.0 million in depreciable assets since July
1, 1995.
 
                                      S-20
<PAGE>
    Interest expense for the six months ended June 30, 1996, was $3.2 million as
compared to $1.2 million for the comparable period in 1995. For the six months
ended June 30, 1996, interest expense represents weighted average borrowings of
$99.6 million under the Partnership's credit facilities at a weighted average
interest rate of 6.4%.
 
    Interest income was $0.3 million for the six months ended June 30, 1996, as
compared to $0.04 million for the six months ended June 30, 1995. Interest
income in 1996 represents earnings on overnight deposits and amounts outstanding
under the 1995 Employee Stock Purchase and Loan Plan.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    Cash provided from operations grew to $23.3 million for the six months ended
June 30, 1996, from $15.9 million for the six months ended June 30, 1995. This
increase is a result of the Partnership's net income growing $6.6 million, or
51.2%, over the prior six month period, primarily as a result of the increase in
number of facilities owned, and the improvement of operations at the facilities
acquired.
 
    During the first six months of 1996, the Partnership acquired 32 facilities
totaling 2,057,000 square feet for a purchase price of $114.4 million, including
the issuance of 246,000 Units valued at $8.0 million. In addition to its
acquisitions during the period, the Partnership opened a newly constructed
68,000 square foot facility in Northern Virginia and a 28,000 square foot
expansion to a facility in Sarasota, Florida. The Partnership currently has
plans to develop 19 new facilities, primarily in the Washington, D.C., and
Memphis, Tennessee, areas. Of these, five projects are under construction or are
in construction planning, with expected costs totaling $14.0 million and
completion dates anticipated to be in the second quarter of 1997. Expansions are
planned for 14 existing facilities, and of these, 10 are under way with planned
completion dates ranging from the fourth quarter of 1996 to the second quarter
of 1997. Estimated costs of the 10 expansions under way are $10.2 million.
 
    At June 30, 1996, the Partnership had $147.4 million of borrowings
outstanding under its credit facilities, $3.4 million of fixed rate debt
maturing in 2001, $2.3 million of fixed rate debt maturing in 2006, and $0.9
million of fixed rate debt maturing in 2000. During the quarter, the Partnership
assumed two variable rate mortgages totaling $7.0 million and maturing in 2001.
The weighted average balance and interest rate on these mortgages was $4.6
million and 9.01%, respectively. The Partnership had $7.6 million of unused
borrowing capacity under its lines of credit at June 30, 1996.
 
    During the period, the Partnership issued approximately 246,000 Units valued
at approximately $8.0 million in connection with the acquisition of facilities.
 
    During the period, the Company issued 1,948,882 shares of Common Stock to
USRealty for net proceeds of $61.0 million. The net proceeds were contributed to
the Partnership in exchange for Units and used to repay borrowings under the
Partnership's revolving lines of credit.
 
FUNDS FROM OPERATIONS
 
    The Partnership believes that FFO should be considered in conjunction with
its net income and cash flows to facilitate a clear understanding of its results
of operations. FFO is defined as net income, computed in accordance with GAAP,
excluding gains (losses) from debt restructuring and sales of property, plus
depreciation and amortization, and after adjustments for unconsolidated
partnerships and joint ventures. FFO should not be considered an alternative to
net income as a measure of the Partnership's performance or to cash flows as a
measure of liquidity.
 
    Effective January 1, 1996, the National Association of Real Estate
Investment Trusts amended its definition of FFO. The impact on the Partnership
of conforming to the amended definition was to reduce FFO by approximately
$240,000 and $87,000 for the six month periods ended June 30, 1996 and June 30,
1995, respectively. Because of the change in the definition of FFO, FFO for the
Partnership may not be comparable to similarly titled measures of operating
performance disclosed by other companies.

    The Company, in order to qualify as a REIT, is required to distribute a
substantial portion of its net income as dividends to its shareholders. It is
the intent of the Partnership that cash distributions will be made for each
fiscal year to enable the Company to meet its distribution requirements for
qualification as a REIT. While the Partnership's goal is to generate and retain
sufficient cash flow to meet its operating, capital, and debt service needs, its
dividend requirements may require the Partnership to utilize its bank lines of
credit to finance property acquisitions and development and major capital
improvements. For the year ended December 31, 1995, distributions were
approximately 85% of the Company's FFO.
 
    The Partnership has incurred approximately $0.43 million for regularly
scheduled maintenance and repairs during the six months ended June 30, 1996. For
the year, the Partnership expects to incur approximately $1.2 million for
scheduled maintenance and repairs and approximately $5.9 million to conform
facilities acquired to Partnership standards.
 
    The Partnership believes that its liquidity and capital resources are
adequate to meet its cash requirements relating to its existing operations for
the next twelve months.

                              DESCRIPTION OF NOTES
 
    THE FOLLOWING SUMMARY SETS FORTH CERTAIN TERMS AND PROVISIONS OF THE NOTES
AND THE INDENTURE (AS DEFINED BELOW) AND IS QUALIFIED IN ITS ENTIRETY BY
REFERENCE TO THE TERMS AND PROVISIONS OF THE NOTES AND THE INDENTURE, WHICH ARE
INCORPORATED HEREIN BY REFERENCE. CAPITALIZED TERMS NOT OTHERWISE DEFINED HEREIN
SHALL HAVE THE MEANINGS GIVEN TO THEM IN THE NOTES AND IN THE INDENTURE. THE
FOLLOWING DESCRIPTION OF THE PARTICULAR TERMS OF THE NOTES OFFERED HEREBY (WHICH
ARE INCLUDED IN THE "DEBT SECURITIES" DESCRIBED IN THE ACCOMPANYING PROSPECTUS)
SUPPLEMENTS, AND, TO THE EXTENT INCONSISTENT THEREWITH, REPLACES THE DESCRIPTION
OF THE GENERAL TERMS AND PROVISIONS OF THE DEBT SECURITIES SET FORTH IN THE
PROSPECTUS.
 
GENERAL
 
    The Notes are to be issued pursuant to an Indenture, dated as of November 1,
1996 (the "Indenture"), between the Partnership and The First National Bank of
Chicago, as Trustee (the "Trustee"). The Notes will be limited to $100,000,000
in aggregate principal amount. The terms of the Notes include those provisions
contained in the Notes and the Indenture and those made part of the Indenture by
reference to the Trust Indenture Act of 1939, as amended (the "TIA"). The Notes
are subject to all such terms, and holders of Notes are referred to the Notes
and the Indenture and the TIA for a statement thereof. Copies of the Indenture
and the form of the Notes are available for inspection at the office of the
Trustee located at One First National Plaza -- Suite 0126, Chicago, Illinois
60670.
 
    The Notes will be direct, unsecured and unsubordinated obligations of the
Partnership and will rank PARI PASSU with each other and all other unsecured and
unsubordinated indebtedness of the Partnership from time to time outstanding.
However, the Notes will be effectively subordinated to mortgages and other
secured indebtedness of the Partnership. As of September 30, 1996, the
Partnership had outstanding $66.1 million of unsecured, unsubordinated debt and
$18.0 million of secured debt. On a pro forma basis, after giving effect to the
completion of the Offering, as of September 30, 1996, the Partnership would have
had outstanding $100.0 million of unsecured, unsubordinated indebtedness, $18.0
million in secured indebtedness and $735.5 million in unencumbered assets.
Subject to certain limitations set forth in the Notes and the Indenture
described in the Prospectus under the caption "Description of Debt Securities --
Certain Covenants," the Indenture will permit the Partnership to incur
additional indebtedness and additional secured indebtedness.
 
    The Notes will be issued only in fully registered, book-entry form, in
denominations of $1,000 and integral multiples thereof, except under the limited
circumstances described below under "-- Book-Entry System."
 
PAYMENT OF PRINCIPAL AND INTEREST ON THE NOTES
 
    Interest on the Notes will accrue at the rate set forth on the cover page of
this Prospectus Supplement from November 1, 1996, or the most recent Interest
Payment Date (as defined below) to which interest has been paid or provided for,
and will be payable in U.S. Dollars semi-annually in arrears on May 1 and
November 1 of each year (each, an "Interest Payment Date"), commencing May 1,
1997. The interest so payable will be paid to the person (the "Holder") in whose
name the applicable Note is registered at the close of business on the April 15
or October 15, as the case may be, (whether or not a Business Day, as defined
below) next preceding the applicable Interest Payment Date (each, a "Regular
Record Date"). The principal of each Note payable on the Maturity Date will be
paid in U.S. Dollars against presentation and surrender thereof at the Corporate
Trust Office of the Trustee located at 14 Wall Street, 8th Floor, Window 2, New
York, New York 10005. Interest on the Notes will be computed on the basis of a
360-day year consisting of twelve 30-day months.
 
MATURITY
 
    The Notes will mature on November 1, 2003. The Notes may be redeemed at the
option of the Partnership at any time. See "-- Optional Redemption." The Notes
will not be entitled to the benefit of any sinking fund.
 
                                      S-29
<PAGE>
OPTIONAL REDEMPTION
 
    The Notes may be redeemed at any time at the option of the Partnership, in
whole or from time to time in part, at a redemption price equal to the sum of
(i) the principal amount of the Notes (or portion thereof) being redeemed plus
accrued interest thereon to the redemption date and (ii) the Make-Whole Amount
(as defined below), if any, with respect to such Notes (or portion thereof) (the
"Redemption Price").
 
    If notice has been given as provided in the Indenture and funds for the
redemption of any Notes (or any portion thereof) called for redemption shall
have been made available on the redemption date referred to in such notice, such
Notes (or any portion thereof) will cease to bear interest on the date fixed for
such redemption specified in such notice and the only right of the Holders of
such Notes will be to receive payment of the Redemption Price.
 
    Notice of any optional redemption of any Notes (or any portion thereof) will
be given to Holders at their addresses, as shown in the security register for
such Notes, not more than 60 nor less than 30 days prior to the date fixed for
redemption. The notice of redemption will specify, among other items, the
Redemption Price and the principal amount of the Notes held by such Holder to be
redeemed.
 
    The Partnership will notify the Trustee at least 60 days prior to giving
notice of redemption (or such shorter period as is satisfactory to the Trustee)
of the aggregate principal amount of such Notes to be redeemed and their
redemption date. If less than all of the Notes are to be redeemed at the option
of the Partnership, the Trustee shall select, in such manner as it shall deem
fair and appropriate, such Notes to be redeemed in whole or in part.
 
    As used herein:
 
    "MAKE-WHOLE AMOUNT"  means, in connection with any optional redemption or
accelerated payment of any Notes, the excess, if any, of (i) the aggregate
present value as of the date of such redemption or accelerated payment of each
dollar of principal being redeemed or paid and the amount of interest (exclusive
of interest accrued to the date of redemption or accelerated payment) that would
have been payable in respect of each such dollar if such redemption or
accelerated payment had not been made, determined by discounting, on a
semi-annual basis, such principal and interest at the Reinvestment Rate
(determined on the third Business Day preceding the date such notice of
redemption is given or declaration of acceleration is made) from the respective
dates on which such principal and interest would have been payable if such
redemption or accelerated payment had not been made, over (ii) the aggregate
principal amount of the Notes being redeemed or paid.
 
    "REINVESTMENT RATE"  means .20% plus the arithmetic mean of the yields under
the respective heading "Week Ending" published in the most recent Statistical
Release under the caption "Treasury Constant Maturities" for the maturity
(rounded to the nearest month) corresponding to the remaining life to maturity,
as of the payment date of the principal being redeemed or paid. If no maturity
exactly corresponds to such maturity, yields for the two published maturities
most closely corresponding to such maturity shall be calculated pursuant to the
immediately preceding sentence and the Reinvestment Rate shall be interpolated
or extrapolated from such yields on a straight-line basis, rounding in each of
such relevant periods to the nearest month. For the purpose of calculating the
Reinvestment Rate, the most recent Statistical Release published prior to the
date of determination of the Make-Whole Amount shall be used.
 
    "STATISTICAL RELEASE"  means the statistical release designated "H.15 (519)"
or any successor publication which is published weekly by the Federal Reserve
System and which establishes yields on actively traded United States government
securities adjusted to constant maturities, or, if such statistical release is
not published at the time of any determination under the Indenture, then such
other reasonably comparable index which shall be designated by the Partnership.
 
                                      S-30
<PAGE>
ADDITIONAL COVENANT
 
    In addition to the limitations on the incurrence of Indebtedness described
in the Prospectus under the caption "Description of Debt Securities -- Certain
Covenants -- Limitations on Incurrence of Indebtedness," for so long as there
are any Outstanding Debt Securities (other than Debt Securities not entitled, by
their terms, to the benefit of this covenant), the Partnership will not, and
will not permit any Subsidiary to, incur any Secured Indebtedness of the
Partnership or any Subsidiary if, immediately after giving effect to the
incurrence of such additional Secured Indebtedness, the aggregate principal
amount of all outstanding Secured Indebtedness of the Partnership and its
Subsidiaries on a consolidated basis would be greater than 40% of Adjusted Total
Assets.
 
    As used herein, "Secured Indebtedness" means Indebtedness secured by any
mortgage, trust deed, deed of trust, deed to secure debt, security agreement,
pledge, conditional sale or other title retention agreement, capitalized lease,
or other like agreement granting or conveying security title to or a security
interest in real property or other tangible assets.
 
SATISFACTION AND DISCHARGE OF THE INDENTURE
 
    The Indenture will, under certain circumstances, upon the Partnership's
request cease to be of further effect with respect to the Notes, and the Trustee
will execute proper instruments acknowledging satisfaction and discharge of its
Indenture as to the Notes. See "Description of Debt Securities -- Defeasance and
Covenant Defeasance" in the accompanying Prospectus.
 
BOOK-ENTRY SYSTEM
 
    The Notes will be issued in the form of a single fully-registered Note in
book-entry form (the "Global Note") which will be deposited with, or on behalf
of, The Depository Trust Company ("DTC") and registered in the name of DTC's
nominee. Except as set forth below, the Global Note may not be transferred
except as a whole by DTC to a nominee of DTC or by a nominee of DTC to DTC or
another nominee of DTC or by DTC or any such nominee to a successor of DTC or a
nominee of such successor.
 
    So long as DTC or its nominee is the registered owner of the Global Note,
DTC or its nominee, as the case may be, will be considered the sole Holder of
the Notes represented by the Global Note for all purposes under the Indenture
and the beneficial owners of the Notes will be entitled only to those rights and
benefits afforded to them in accordance with DTC's regular operating procedures.
Upon specified written instructions of a Participant (defined below), DTC will
have its nominee assist Participants in the exercise of certain Holders' rights,
such as a demand for acceleration or an instruction to the Trustee. Except as
provided below, owners of beneficial interests in the Global Note will not be
entitled to have Notes registered in their names, will not receive or be
entitled to receive physical delivery of Notes in certificated form and will not
be considered the registered owners or Holders thereof under the Indenture.
 
    If (i) DTC is at any time unwilling or unable to continue as depository or
if at any time DTC ceases to be a clearing agency registered under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"), and a
successor depository is not appointed by the Partnership within 90 days, (ii) an
Event of Default under the Indenture has occurred and is continuing and the
beneficial owners representing a majority in principal amount of the Notes
advise DTC to cease acting as depository or (iii) the Partnership, in its sole
discretion, determines at any time that the Notes shall no longer be represented
by the Global Note, the Partnership will issue individual Notes of the
applicable amount and in certificated form in exchange for the Global Note. In
any such instance, an owner of a beneficial interest in the Global Note will be
entitled to physical delivery of individual Notes in certificated form of like
tenor, equal in principal amount to such beneficial interest and to have such
Notes in certificated form registered in its name. Notes so issued in
certificated form will be issued in denominations of $1,000 or any integral
multiple thereof, and will be issued in registered form only, without coupons.
 
                                      S-31
<PAGE>
    The following is based on information furnished by DTC:
 
        DTC is a limited-purpose trust company organized under the New York
    Banking Law, a "banking organization" within the meaning of the New York
    Banking Law, a member of the Federal Reserve System, a "clearing
    corporation" within the meaning of the New York Uniform Commercial Code, and
    a "clearing agency" registered pursuant to the provisions of Section 17A of
    the Exchange Act. DTC holds securities that its participants
    ("Participants") deposit with DTC. DTC also facilitates the settlement among
    Participants of securities transactions, such as transfers and pledges, in
    deposited securities through electronic computerized book-entry changes in
    Participants' accounts, thereby eliminating the need for physical movement
    of securities certificates. Direct Participants include securities brokers
    and dealers, banks, trust companies, clearing corporations and certain other
    organizations ("Direct Participants"). DTC is owned by a number of its
    Direct Participants and by the New York Stock Exchange, Inc., the American
    Stock Exchange, Inc. and the National Association of Securities Dealers,
    Inc. Access to the DTC system is also available to others such as securities
    brokers and dealers, banks and trust companies that clear through or
    maintain a custodial relationship with a Direct Participant, either directly
    or indirectly ("Indirect Participants"). The rules applicable to DTC and its
    Participants are on file with the Securities and Exchange Commission.
 
        Purchases of Notes under the DTC system must be made by or through
    Direct Participants, which will receive a credit for the Notes on DTC's
    records. The ownership interest of each actual purchaser of each Note
    ("Beneficial Owner") is in turn recorded on the Direct and Indirect
    Participant's records. A Beneficial Owner does not receive written
    confirmation from DTC of its purchase, but such Beneficial Owner is expected
    to receive a written confirmation providing details of the transaction, as
    well as periodic statements of its holdings, from the Direct or Indirect
    Participant through which such Beneficial Owner entered into the
    transaction. Transfers of ownership interests in Notes are accomplished by
    entries made on the books of Participants acting on behalf of Beneficial
    Owners. Beneficial Owners do not receive certificates representing their
    ownership interests in the Notes, except in the event that use of the
    book-entry system for the Notes is discontinued.
 
    To facilitate subsequent transfers, the Global Note is registered in the
name of DTC's partnership nominee, Cede & Co. The deposit of the Global Note
with DTC and its registration in the name of Cede & Co. effects no change in
beneficial ownership. DTC has no knowledge of the actual Beneficial Owners of
the Notes; DTC's records reflect only the identity of the Direct Participants to
whose accounts the Notes are credited, which may or may not be the Beneficial
Owners. The Participants remain responsible for keeping account of their
holdings on behalf of their customers.
 
    Delivery of notices and other communications by DTC to Direct Participants,
by Direct Participants to Indirect Participants and by Direct Participants and
Indirect Participants to Beneficial Owners are governed by arrangements among
them, subject to any statutory or regulatory requirements as may be in effect
from time to time.
 
    Neither DTC nor Cede & Co. will consent or vote with respect to the Notes.
Under its usual procedures, DTC mails a proxy (an "Omnibus Proxy") to the issuer
as soon as possible after the record date. The Omnibus Proxy assigns Cede &
Co.'s consenting or voting rights to those Direct Participants to whose accounts
the Notes are credited on the record date (identified on a list attached to the
Omnibus Proxy).
 
    Principal and interest payments on the Notes will be made by the Partnership
to the Trustee and from the Trustee to DTC. DTC's practice is to credit Direct
Participant's accounts on the payable date in accordance with their respective
holdings as shown on DTC's records unless DTC has reason to believe that it will
not receive payment on the payable date. Payments by Participants to Beneficial
Owners will be governed by standing instructions and customary practices, as is
the case with securities held for the accounts of customers in bearer form or
registered in "street name," and will be the responsibility of such Participant
and not of DTC, the Trustee or the Partnership subject to any statutory or
regulatory requirements as may be in effect from time to time. Payment of
principal and interest to DTC is the
 
                                      S-32
<PAGE>
responsibility of the Partnership or the Trustee, disbursement of such payments
to Direct Participants is the responsibility of DTC, and disbursement of such
payments to the Beneficial Owners is the responsibility of Direct and Indirect
Participants.
 
    DTC may discontinue providing its services as securities depository with
respect to the Notes at any time by giving reasonable notice to the Partnership
or the Trustee. Under such circumstances, in the event that a successor
securities depository is not appointed, Note certificates are required to be
printed and delivered.
 
    The Partnership may decide to discontinue use of the system of book-entry
transfers through DTC (or a successor securities depository). In that event,
Note certificates will be printed and delivered.
 
    None of the Partnership, the Underwriters or the Trustee will have any
responsibility or liability for any aspect of the records relating to or
payments made on account of beneficial interests in the Global Note, or for
maintaining, supervising or reviewing any records relating to such beneficial
interests.
 
SAME-DAY SETTLEMENT AND PAYMENT
 
    Settlement for the Notes will be made in immediately available funds. All
payments of principal and interest in respect of the Notes will be made by the
Partnership in immediately available funds.
 
    Secondary trading in long-term notes and debentures of corporate issuers is
generally settled in clearing house or next-day funds. In contrast, the Notes
will trade in DTC's Same-Day Funds Settlement System until maturity, or until
the Notes are issued in certificated form, and secondary market trading activity
in the Notes will therefore be required by DTC to settle in immediately
available funds. No assurance can be given as to the effect, if any, of
settlement in immediately available funds on trading activity in the Notes.
 
                                  UNDERWRITING
 
    Subject to the terms and conditions of the Underwriting Agreement and the
Pricing Agreement, the Partnership has agreed to sell to each of the
Underwriters named below, and each of such Underwriters has severally agreed to
purchase, the principal amount of the Notes set forth opposite its name below:

</TABLE>
 
    Under the terms and conditions of the Underwriting Agreement and the Pricing
Agreement, the Underwriters are committed to take all of the Notes, if any are
taken.
 
    The Underwriters propose to offer the Notes in part directly to the public
at the initial public offering price set forth on the cover page of this
Prospectus Supplement and in part to certain securities dealers at such price
less a concession of .40% of the principal amount of the Notes. The Underwriters
may allow, and such dealers may reallow, a concession not in excess of .25% of
the principal amount of the Notes to certain brokers and dealers. After the
Notes are released for sale to the public, the offering price and other selling
terms may from time to time be varied by the Underwriters.
 
    The Notes are a new issue of securities with no established trading market.

    SUSA  Partnership, L.P. (the "Partnership"), may  from time to time offer in
one  or   more  series   unsecured,  non-convertible   debt  securities   ("Debt
Securities")  having an  aggregate initial public  offering price  not to exceed
$250,000,000, on  terms to  be determined  at  the time  of offering.  The  Debt
Securities  may be offered by the Partnership in separate series, in amounts, at
prices and on terms to be determined at the time of sale and to be set forth  in
a  supplement  to  this Prospectus  (a  "Prospectus Supplement").  At  least one
nationally recognized  statistical rating  organization  will have  assigned  an
investment grade rating to the Debt Securities at the time of sale.
 
    The  Debt  Securities  will  be  effectively  subordinated  to  any  secured
indebtedness of the  Partnership. At March  31, 1996, the  Partnership had  $6.6
million  in secured indebtedness  outstanding. The Debt  Securities will rank in
PARI PASSU  with all  other  unsecured and  unsubordinated indebtedness  of  the
Partnership. Subject to certain limitations set forth in the indenture regarding
the  Debt Securities, the Partnership may  incur additional secured or unsecured
indebtedness. See  "Description  of  Debt Securities  --  Certain  Covenants  --
Limitations   on  Incurrence   of  Indebtedness."  Except   as  described  under
"Description  of  Debt   Securities  --  Merger,   Consolidation  or  Sale"   or
"Description  of Debt Securities -- Certain Covenants" or as may be set forth in
any Prospectus  Supplement,  the  applicable  indenture  will  not  contain  any
provisions that would limit the ability of the Partnership to incur indebtedness
or that would afford holders of the Debt Securities protection in the event of a
significant  transaction involving the Partnership that may adversely affect the
holders of the Debt Securities.
 
    The specific  terms  of  the  Debt  Securities  in  respect  of  which  this
Prospectus  is being  delivered will be  set forth in  the applicable Prospectus
Supplement and will include the specific title, aggregate principal amount, form
(which may be certificated or global), authorized denominations, maturity,  rate
(or  manner of calculation thereof)  and time of payment  of interest, terms for
redemption at the option of  the Partnership or repayment  at the option of  the
holder,  terms  for sinking  fund payments,  covenants,  and any  initial public
offering  price.  The  applicable   Prospectus  Supplement  will  also   contain
information,  where applicable, concerning material United States federal income
tax considerations relating to, and any listing on a securities exchange of, the
Debt Securities covered thereby.
 
    The Debt Securities may be offered directly, through agents designated  from
time  to time by the  Partnership, or to or  through underwriters or dealers. If
any designated  agents or  any underwriters  are involved  in the  sale of  Debt
Securities,  they will be identified and their compensation will be described in
the applicable  Prospectus  Supplement.  See "Plan  of  Distribution."  No  Debt
Securities  may be sold without delivery of the applicable Prospectus Supplement
describing such  Debt  Securities and  the  method  and terms  of  the  offering
thereof.

                                THE PARTNERSHIP
 
    The  Partnership is  managed by its  general partner, Storage  USA, Inc. The
Company is a  self-managed, self-advised real  estate investment trust  ("REIT")
engaged   in  the  business  of   owning,  managing,  acquiring  and  developing
self-storage facilities. The Company operates through the Partnership, in  which
it  owns approximately a  95% interest and through  SUSA Management, Inc., which
provides self-storage management and ancillary  services to the Partnership  and
in  which  the Partnership  owns  a 99%  economic  interest. The  description of
business, property information, policies with respect to certain activities  and
management  information for the Partnership  are substantially identical to that
of the Company. Such information may be found in the Company's Annual Report  on
Form 10-K for the year ended December 31, 1995, as amended, and in the Company's
1996  Annual Meeting Proxy Statement filed April 5, 1996. At March 31, 1996, the
Partnership owned 166  facilities containing  11.1 million  net rentable  square
feet  in  24 states  and  the District  of Columbia  and  managed for  others 29
facilities containing  an  additional  1.8 million  net  rentable  square  feet.
Average  physical  and  economic  occupancy  for  the  facilities  owned  by the
Partnership at March 31, 1996, were 88% and 81%, respectively. Average  weighted
annual rent per square foot for these facilities was $9.40.
 
    The  Partnership is  a Tennessee  limited partnership  and the  Company is a
Tennessee corporation.  Their  executive offices  are  located at  10440  Little
Patuxent  Parkway,  Suite 1100,  Columbia,  Maryland 21044  and  their telephone
number is (410) 730-9500.
 
                                USE OF PROCEEDS
 
    Unless otherwise set forth in the applicable Prospectus Supplement, the  net
proceeds  from the sale of  any Debt Securities will  be used by the Partnership
for general partnership purposes, which  may include repayment of  indebtedness,
making  improvements  to  properties  and  the  acquisition  and  development of
additional properties.
 
                      RATIOS OF EARNINGS TO FIXED CHARGES
 
    The Partnership's ratio of earnings to  fixed charges for the quarter  ended
March  31, 1996 was 5.43 and for the year ended December 31, 1995, was 7.73. For
the period  January 1,  1994, through  March 23,  1994, fixed  charges  exceeded
earnings  by $165,000. The Partnership's ratio  of earnings to fixed charges for
the period March 24, 1994, to December  31, 1994 was 9.38 and the  Partnership's
pro  forma ratio of  earnings to fixed  charges for the  year ended December 31,
1994, was 8.63.  The pro forma  results of  operations from which  the ratio  of
earnings  to  fixed charges  for 1994  is  calculated reflect  the Partnership's
annual results  of  operations and  assume  that the  Company's  initial  public
offering  and  related  transactions,  including  the  contribution  of  the net
proceeds from such  offering to the  Partnership, were completed  on January  1,
1994.  The Partnership's ratio of earnings to  fixed charges for the years ended
December 31, 1993  was 1.10. For  the years  ended December 31,  1992 and  1991,
respectively, fixed charges exceeded earnings by $3.0 and $4.2 million.
 
    The  ratios of earnings to fixed  charges were computed by dividing earnings
by fixed charges. For  purposes of computing these  ratios, earnings consist  of
income  before  extraordinary items  plus fixed  charges other  than capitalized
interest, and fixed  charges consist  of interest on  borrowed funds  (including
capitalized  interest) and amortization  of debt discount  and expense. To date,
the Partnership  has not  issued  any preferred  interests in  the  Partnership;
therefore,  the ratios of earnings to combined fixed charges and preferred share
dividends are identical.
 
                         DESCRIPTION OF DEBT SECURITIES
 
    The following description sets forth certain general terms and provisions of
the  Debt  Securities  to  which  any  Prospectus  Supplement  may  relate.  The
particular  terms of the Debt  Securities being offered and  the extent to which
such general provisions may apply will  be described in a Prospectus  Supplement
relating to such Debt Securities.
 
                                       3
<PAGE>
    The  Debt Securities  will be issued  under an  indenture to be  dated as of
November  1,  1996,  as  amended  or   supplemented  from  time  to  time   (the
"Indenture"), between the Partnership and The First National Bank of Chicago, as
trustee  (the "Trustee").  The Indenture  has been  filed as  an exhibit  to the
Registration Statement of which this Prospectus  is a part and is available  for
inspection  at the corporate trust  services office of the  Trustee at One First
National Plaza --  Suite 0126,  Chicago, Illinois  60670 or  as described  above
under "Available Information." The Indenture is subject to, and governed by, the
Trust  Indenture  Act  of 1939,  as  amended  (the "TIA").  The  statements made
hereunder relating  to  the Indenture  and  the  Debt Securities  to  be  issued
thereunder  are summaries of certain provisions thereof and do not purport to be
complete and are subject  to, and are qualified  in their entirety by  reference
to,  all provisions of the Indenture and such Debt Securities. Capitalized terms
used but not defined herein shall have the respective meanings set forth in  the
Indenture.
 
    Wherever  particular Sections or defined terms of the Indenture are referred
to herein or  in a  Prospectus Supplement, such  Sections or  defined terms  are
incorporated by reference herein or therein, as the case may be.
 
GENERAL
 
    The Debt Securities will be direct, unsecured obligations of the Partnership
and  will  rank  in  PARI  PASSU with  all  other  unsecured  and unsubordinated
indebtedness of the  Partnership. The  Debt Securities  are non-convertible  and
will be effectively subordinated to any secured indebtedness of the Partnership.
At  least one  nationally recognized  statistical rating  organization will have
assigned an investment grade rating to the Debt Securities at the time of  sale.
At  March 31,  1996, the  Partnership had  $6.6 million  in secured indebtedness
outstanding. The Debt  Securities may be  issued without limit  as to  aggregate
principal  amount, in one or more series,  in each case as established from time
to time in  or pursuant to  authority granted by  a resolution of  the Board  of
Directors  of  the Company  as sole  general  partner of  the Partnership  or as
established in  the Indenture  in one  or more  indentures supplemental  to  the
Indenture. All Debt Securities of one series need not be issued at the same time
and, unless otherwise provided, a series may be reopened, without the consent of
the  holders of the Debt Securities of  such series, for issuances of additional
Debt Securities of such series (Section 301).
 
    The Indenture provides that there may  be more than one Trustee  thereunder,
each  with respect to one  or more series of  Debt Securities. Any Trustee under
the Indenture may resign  or be removed  with respect to one  or more series  of
Debt Securities, and a successor Trustee may be appointed to act with respect to
such  series (Section 610). In the event that  two or more persons are acting as
Trustee with respect to different series  of Debt Securities, each such  trustee
shall  be a Trustee of a trust under the applicable Indenture separate and apart
from the trust administered by any  other Trustee (Section 609), and, except  as
otherwise indicated herein, any action described herein to be taken by a Trustee
may be taken by each such Trustee with respect to, and only with respect to, the
one  or  more  series of  Debt  Securities for  which  it is  Trustee  under the
applicable Indenture.
 
    The applicable Prospectus Supplement will set  forth the price or prices  at
which  the Debt Securities  to be offered  will be issued  and will describe the
following terms of such Debt Securities: (1) the title of such Debt  Securities;
(2)  any limit on the aggregate principal  amount of such Debt Securities or the
series of which they are a part; (3)  the Person to whom any interest on a  Debt
Security  shall be  payable, if  other than  the Person  in whose  name the Debt
Security is registered; (4) the date or  dates on which the principal of any  of
such Debt Securities will be payable; (5) the rate or rates at which any of such
Debt  Securities will bear  interest, if any,  the date or  dates from which any
such interest will accrue, the Interest Payment Dates on which any such interest
will be payable and the Regular Record Date for any such interest payable on any
Interest Payment Date; (6) the  place or places where  the principal of and  any
premium  and interest on  any of such  Debt Securities will  be payable; (7) the
period or periods within which, the price  or prices at which and the terms  and
conditions  on which any of such Debt Securities may be redeemed, in whole or in
part, at the  option of  the Partnership;  (8) the  obligation, if  any, of  the
Partnership  to redeem or purchase  any of such Debt  Securities pursuant to any
sinking fund or analogous provision or at the option of the Holder thereof,  and
the  period or periods within which, the price or prices at which, and the terms
and   conditions   on   which   any   of   such   Debt   Securities   will    be
 
                                       4
<PAGE>
redeemed or purchased, in whole or in part, pursuant to any such obligation; (9)
the  denominations in  which any  of such Debt  Securities will  be issuable, if
other than denominations of  $1,000 and any integral  multiple thereof; (10)  if
the  amount of  principal of  or any  premium or  interest on  any of  such Debt
Securities may  be  determined with  reference  to an  index  or pursuant  to  a
formula, the manner in which such amounts will be determined; (11) if other than
the  entire principal amount thereof, the portion of the principal amount of any
of such Debt Securities which will  be payable upon declaration of  acceleration
of  the Maturity  thereof; (12)  if the principal  amount payable  at the Stated
Maturity of any of such Debt Securities  will not be determinable as of any  one
or  more dates prior to the Stated Maturity,  the amount which will be deemed to
be such principal  amount as of  any such  date for any  purpose, including  the
principal  amount thereof which will be due  and payable upon any Maturity other
than the Stated Maturity  or which will  be deemed to be  Outstanding as of  any
such  date (or,  in any  such case,  the manner  in which  such deemed principal
amount is to be determined); (13)  if applicable, that such Debt Securities,  in
whole  or any specified part,  are defeasible pursuant to  the provisions of the
Indenture described under "-- Defeasance  and Covenant Defeasance --  Defeasance
and   Discharge"  or  "--   Defeasance  and  Covenant   Defeasance  --  Covenant
Defeasance", or  under  both  such  captions; (14)  whether  any  of  such  Debt
Securities  will be  issuable in whole  or in  part in the  form of  one or more
Global Debt Securities and, if so,  the respective Depositaries for such  Global
Debt  Securities, the  form of  any legend or  legends to  be borne  by any such
Global Debt Security in addition to or  in lieu of the legend referred to  under
"--  Form, Exchange  and Transfer --  Global Debt Securities"  and, if different
from those described under such caption, any circumstances under which any  such
Global  Debt Security may be  exchanged in whole or  in part for Debt Securities
registered, and any transfer of  such Global Debt Security  in whole or in  part
may  be registered, in the  names of Persons other  than the Depositary for such
Global Debt Security  or its  nominee; (15)  any addition  to or  change in  the
Events  of Default applicable to  any of such Debt  Securities and any change in
the right of the Trustee or the Holders thereof to declare the principal  amount
of  any of such Debt Securities due and  payable; (16) any addition to or change
in the  covenants  in  the  Indenture described  under  "--  Certain  Covenants"
applicable to any of such Debt Securities; and (17) any other terms of such Debt
Securities not inconsistent with the provisions of the Indenture. (Section 301)
 
    Debt  Securities, including Original Issue  Discount Debt Securities, may be
sold at a  substantial discount  below their principal  amount. Certain  special
United  States federal  income tax  considerations (if  any) applicable  to Debt
Securities sold at an original issue discount may be described in the applicable
Prospectus Supplement.
 
    Except as described under "-- Merger, Consolidation or Sale" or "--  Certain
Covenants"  or as may be  set forth in any  Prospectus Supplement, the Indenture
does not contain any provisions that would limit the ability of the  Partnership
to  incur  indebtedness or  that  would afford  holders  of the  Debt Securities
protection in  the  event of  (i)  a  highly leveraged  or  similar  transaction
involving  the Partnership, the management of  the Partnership, or any affiliate
of any  such  party,  (ii)  a  change of  control  or  (iii)  a  reorganization,
restructuring,  merger or similar transaction involving the Partnership that may
adversely affect the holders of the Debt Securities. In addition, subject to the
limitations set forth under "-- Merger, Consolidation or Sale," the  Partnership
may,  in the future, enter into certain transactions, such as the sale of all or
substantially  all  of  its  assets  or  the  merger  or  consolidation  of  the
Partnership, that would increase the amount of the Partnership's indebtedness or
substantially  reduce or eliminate  the Partnership's assets,  which may have an
adverse effect  on  the  Partnership's  ability  to  service  its  indebtedness,
including  the Debt Securities. However, restrictions on ownership and transfers
of the Company's Common Stock designed to preserve its status as a REIT may  act
to  prevent or hinder a  change of control. Reference  is made to the applicable
Prospectus Supplement  for  information  with respect  to  any  deletions  from,
modifications  of or additions  to the events  of default or  covenants that are
described below,  including  any  addition  of a  covenant  or  other  provision
providing event risk or similar protection.

DENOMINATIONS, REGISTRATION AND TRANSFER
 
    The Debt Securities of each series will be issuable only in fully registered
form,  without  coupons,  and,  unless  otherwise  specified  in  the applicable
Prospectus Supplement, only  in denominations of  $1,000 and integral  multiples
thereof. (Section 302)
 
    At  the option of the Holder, subject to  the terms of the Indenture and the
limitations applicable to Global Debt Securities, Debt Securities of each series
will be  exchangeable  for other  Debt  Securities of  the  same series  of  any
authorized  denomination and  of a  like tenor  and aggregate  principal amount.
(Section 305)
 
    Subject to the  terms of  the Indenture  and the  limitations applicable  to
Global  Debt  Securities,  Debt  Securities may  be  presented  for  exchange as
provided above or for registration of  transfer (duly endorsed or with the  form
of  transfer  endorsed thereon  duly  executed) at  the  office of  the Security
Registrar or at the office of  any transfer agent designated by the  Partnership
for  such  purpose. No  service  charge will  be  made for  any  registration of
transfer or exchange of Debt Securities, but the Partnership may require payment
of a sum sufficient  to cover any  tax or other  governmental charge payable  in
connection  therewith.  Such  transfer or  exchange  will be  effected  upon the
Security Registrar or such transfer agent,  as the case may be, being  satisfied
with  the documents of title and identity  of the person making the request. The
Partnership has appointed the Trustee as Security Registrar. Any transfer  agent
(in  addition to the Security Registrar) initially designated by the Partnership
for any Debt Securities will be  named in the applicable Prospectus  Supplement.
(Section  305) The  Partnership may  at any  time designate  additional transfer
agents or rescind the designation of any  transfer agent or approve a change  in
the  office through which  any transfer agent acts,  except that the Partnership
will be required to maintain a transfer  agent in each Place of Payment for  the
Debt Securities of each series. (Section 1002)
 
    If  the Debt Securities of any series (or of any series and specified terms)
are to be redeemed in part, the  Partnership will not be required (i) to  issue,
register  the transfer of  or exchange any  Debt Security of  that series (or of
that series and specified terms, as the  case may be) during a period  beginning
at  the opening of  business 15 days  before the day  of mailing of  a notice of
redemption of any  such Debt Security  that may be  selected for redemption  and
ending at the close of business on the day of such mailing, (ii) to register the
transfer  of or exchange any Debt Security  so selected for redemption, in whole
or in  part, except  the unredeemed  portion  of any  such Debt  Security  being
redeemed  in part or  (iii) to issue,  register the transfer  of or exchange any
Debt Security that has been surrendered for payment at the option of the Holder,
except the portion, if any, of such Debt Security not to be so repaid.  (Section
305)
 
GLOBAL DEBT SECURITIES
 
    Some  or all  of the Debt  Securities of  any series may  be represented, in
whole or in  part, by  one or  more Global Debt  Securities which  will have  an
aggregate  principal amount  equal to  that of  the Debt  Securities represented
thereby. Each  Global  Debt  Security  will  be registered  in  the  name  of  a
Depositary  or  a  nominee  thereof  identified  in  the  applicable  Prospectus
Supplement, will be  deposited with such  Depositary or nominee  or a  custodian
therefor  and will  bear a  legend regarding  the restrictions  on exchanges and
registration of transfer thereof referred to below and any such other matters as
may be provided for pursuant to the Indenture. (Section 305)
 
    Notwithstanding  any  provision  of  the  Indenture  or  any  Debt  Security
described  herein, no Global Debt Security may  be exchanged in whole or in part
for Debt Securities  registered, and no  transfer of a  Global Debt Security  in
whole  or in part  may be registered, in  the name of any  Person other than the
Depositary for  such Global  Debt Security  or any  nominee of  such  Depositary
unless  (i) the Depositary has notified the  Partnership that it is unwilling or
unable to continue as Depositary for such Global Debt Security or has ceased  to
be  qualified to act as such as required by the Indenture, (ii) there shall have
occurred and  be  continuing  an Event  of  Default  with respect  to  the  Debt
Securities  represented by such Global Debt  Security or (iii) there shall exist
such  circumstances,   if  any,   in   addition  to   or   in  lieu   of   those
 
                                       6
<PAGE>
described  above as  may be  described in  the applicable  Prospectus Supplement
(Section 305). All securities issued in  exchange for a Global Debt Security  or
any  portion thereof  will be  registered in  such names  as the  Depositary may
direct. (Sections 204 and 305)
 
    As long as the  Depositary, or its  nominee, is the  registered Holder of  a
Global  Debt Security, the Depositary or such  nominee, as the case may be, will
be considered the sole  owner and Holder  of such Global  Debt Security and  the
Debt  Securities represented thereby for all  purposes under the Debt Securities
and the Indenture (Section 308). Except in the limited circumstances referred to
above, owners of  beneficial interests  in a Global  Debt Security  will not  be
entitled  to have such  Global Debt Security or  any Debt Securities represented
thereby registered in their  names, will not receive  or be entitled to  receive
physical  delivery of certificated Debt Securities in exchange therefor and will
not be considered to be  the owners or Holders of  such Global Debt Security  or
any  Debt  Securities  represented  thereby  for  any  purpose  under  the  Debt
Securities or the Indenture.  All payments of principal  of and any premium  and
interest  on  a Global  Debt  Security will  be made  to  the Depositary  or its
nominee, as  the  case  may  be,  as  the  Holder  thereof.  The  laws  of  some
jurisdictions  require  that  certain  purchasers  of  securities  take physical
delivery of  such securities  in  definitive form.  These  laws may  impair  the
ability to transfer beneficial interests in a Global Debt Security.
 
    Ownership  of beneficial interests in a Global Debt Security will be limited
to  institutions  that  have  accounts  with  the  Depositary  or  its   nominee
("participants")  and  to persons  that  may hold  beneficial  interests through
participants. In connection with the issuance  of any Global Debt Security,  the
Depositary  will credit, on its book-entry registration and transfer system, the
respective principal amounts of Debt  Securities represented by the Global  Debt
Security  to the accounts of its participants. Ownership of beneficial interests
in a Global  Debt Security  will be  shown only on,  and the  transfer of  those
ownership  interests will  be effected only  through, records  maintained by the
Depositary (with respect  to participants'  interests) or  any such  participant
(with  respect  to  interests of  persons  held  by such  participants  on their
behalf).  Payments,  transfers,  exchanges   and  others  matters  relating   to
beneficial  interests  in  a Global  Debt  Security  may be  subject  to various
policies and procedures adopted by the Depositary from time to time. None of the
Partnership, the Trustee  or any agent  of the Partnership  or the Trustee  will
have  any responsibility or liability for any  aspect of the Depositary's or any
participant's  records  relating  to,  or  for  payments  made  on  account  of,
beneficial  interests in a Global Debt Security, or for maintaining, supervising
or reviewing any records relating to such beneficial interests.
 
    Secondary trading in notes and debentures of corporate issuers is  generally
settled  in clearing-house or next-day  funds. In contrast, beneficial interests
in a Global Debt Security, in some cases, may trade in the Depositary's same-day
funds settlement system,  in which  secondary market trading  activity in  those
beneficial   interests  would  be  required  by  the  Depositary  to  settle  in
immediately available funds. The Partnership cannot predict the effect, if  any,
that settlement in immediately available funds would have on trading activity in
such   beneficial  interests.  Also,  settlement  for  purchases  of  beneficial
interests in a Global  Debt Security upon the  original issuance thereof may  be
required to be made in immediately available funds.
 
PAYMENT AND PAYING AGENTS
 
    Unless  otherwise indicated in the applicable Prospectus Supplement, payment
of interest on a Debt Security on any Interest Payment Date will be made to  the
Person  in  whose name  such  Debt Security  (or  one or  more  Predecessor Debt
Securities) is registered at  the close of business  on the Regular Record  Date
for such interest. (Section 307)
 
    Unless   otherwise  indicated  in   the  applicable  Prospectus  Supplement,
principal of and any premium and interest on the Debt Securities of a particular
series will be payable at  the office of such Paying  Agent or Paying Agents  as
the Partnership may designate for such purpose from time to time, except that at
the  option of  the Partnership  payment of  any interest  may be  made by check
mailed to the address of the Person entitled thereto as such address appears  in
the  Security Register. Unless otherwise  indicated in the applicable Prospectus
Supplement, the corporate trust office  of the Trustee in  the City of New  York
will  be designated  as the  Partnership's sole  Paying Agent  for payments with
respect to Debt Securities of
 
                                       7
<PAGE>
each series. Any other Paying Agents initially designated by the Partnership for
the Debt  Securities of  a particular  series will  be named  in the  applicable
Prospectus  Supplement.  The Partnership  may at  any time  designate additional
Paying Agents or rescind the designation of any Paying Agent or approve a change
in the office through which any  Paying Agent acts, except that the  Partnership
will  be required to  maintain a Paying Agent  in each Place  of Payment for the
Debt Securities of a particular series. (Section 1002)
 
    All moneys paid by the Partnership to a Paying Agent for the payment of  the
principal  of, or  any premium  or interest  on, any  Debt Security  that remain
unclaimed at the end of two years after such principal, premium or interest  has
become due and payable will be repaid to the Partnership, and the Holder of such
Debt  Security thereafter may look only  to the Partnership for payment thereof.
(Section 1003)
 
    Any interest  not punctually  paid  or duly  provided  for on  any  Interest
Payment  Date  with  respect  to a  Debt  Security  ("Defaulted  Interest") will
forthwith cease to  be payable to  the holder on  the applicable regular  record
date  and may either be paid  to the person in whose  name such Debt Security is
registered at  the close  of business  on a  special record  date (the  "Special
Record  Date") for  the payment of  such Defaulted  Interest to be  fixed by the
Trustee, notice whereof SHALL be given to  the holder of such Debt Security  not
less  than 10 days prior to such Special Record Date, or may be paid at any time
in any other lawful manner, all  as more completely described in the  applicable
supplement (Section 307).
 
MERGER, CONSOLIDATION OR SALE
 
    The  Partnership may not consolidate with or merge into, or convey, transfer
or lease its properties and assets  substantially as an entirety to, any  Person
(a  "successor Person"), and may not permit any Person to merge into, or convey,
transfer or lease its properties and assets substantially as an entirety to, the
Partnership, UNLESS  (i)  the  successor  Person  (if  any)  is  a  corporation,
partnership  or  trust organized  and  validly existing  under  the laws  of any
domestic  jurisdiction   and  assumes,   by   a  supplemental   indenture,   the
Partnership's  obligations on the Debt Securities  and under the Indenture, (ii)
immediately  after  giving   effect  to  the   transaction,  and  treating   any
indebtedness which becomes an obligation of the Partnership or any Subsidiary as
a  result of the  transaction as having been  incurred by it at  the time of the
transaction, no Event of Default, and no  event which, after notice or lapse  of
time  or both,  would become  an Event  of Default,  shall have  occurred and be
continuing and (iii) certain other conditions are met. (Section 801)
 
CERTAIN COVENANTS
 
    EXISTENCE.  Except as  permitted under "--  Merger, Consolidation or  Sale,"
the  Partnership will be required to do or cause to be done all things necessary
to preserve  and  keep  in full  force  and  effect its  existence,  rights  and
franchises;  provided, however,  that the Partnership  shall not  be required to
preserve any right or franchise if  it determines that the preservation  thereof
is  no longer desirable in the conduct of its business and that the loss thereof
is not  disadvantageous in  any material  respect  to the  holders of  the  Debt
Securities (Section 1005).
 
    MAINTENANCE  OF PROPERTIES.   The Partnership will be  required to cause all
properties used or useful in the conduct of its business or the business of  any
subsidiary to be maintained and kept in good condition, repair and working order
and  supplied with all necessary equipment and to cause to be made all necessary
repairs, renewals, replacements, betterments and improvements thereof, all as in
the judgment of the Partnership may be necessary so that the business carried on
in connection  therewith may  be properly  and advantageously  conducted at  all
times;  provided,  however, that  the Partnership  shall  not be  prevented from
discontinuing the operation  or maintenance  of any  of its  properties if  such
discontinuance  is, in the judgment of the Partnership, desirable in the conduct
of its business or the business of any Subsidiary and not disadvantageous in any
material respect to the Holders. (Section 1006).
 
    INSURANCE.  The Partnership will  be required to, and  to cause each of  its
subsidiaries  to, keep all  of its insurable properties  insured against loss or
damage with  insurers of  recognized responsibility  in commercially  reasonable
amounts and types (Section 1008).
 
                                       8
<PAGE>
    PAYMENT  OF TAXES AND OTHER CLAIMS.  The Partnership will be required to pay
or discharge or cause  to be paid  or discharged, before  the same shall  become
delinquent,  (i)  all  taxes,  assessments and  governmental  charges  levied or
imposed upon the Partnership  or any subsidiary or  upon the income, profits  or
property  of the Partnership or  any subsidiary, and (ii)  all lawful claims for
labor, materials and supplies which, if unpaid, might by law become a lien  upon
the  property of the Partnership or  any subsidiary; provided, however, that the
Partnership shall not be  required to pay  or discharge or cause  to be paid  or
discharged any such tax, assessment, charge or claim whose amount, applicability
or  validity  is  being  contested in  good  faith  by  appropriate proceedings.
(Section 1007).
 
    PROVISION OF  FINANCIAL INFORMATION.    Whether or  not the  Partnership  is
subject  to Section 13 or Section  15(d) of the Exchange Act  and for so long as
any Debt  Securities  are  outstanding,  the Partnership  will,  to  the  extent
permitted  under the Exchange Act, file  with the Commission the annual reports,
quarterly reports  and other  documents which  the Partnership  would have  been
required  to file  with the  Commission pursuant to  such Section  13 or Section
15(d) (the  "Financial Statements")  if the  Partnership were  so subject,  such
documents  to be filed with  the Commission on or  prior to the respective dates
(the "Required Filing Dates") by which the Partnership would have been  required
so  to file such documents  if the Partnership were  so subject. The Partnership
will also in  any event  (x) within  15 days of  each Required  Filing Date  (i)
transmit  by mail to  all holders of  Debt Securities whose  names appear in the
security register for such Debt Securities  (the "Holders"), as their names  and
addresses appear in the security register for such Debt Securities, without cost
to  such Holders, copies of  the annual reports and  quarterly reports which the
Partnership would have  been required to  file with the  Commission pursuant  to
Section  13 or Section 15(d) of the Exchange Act if the Partnership were subject
to such Sections and (ii)  file with any Trustee  copies of the annual  reports,
quarterly  reports and  other documents  which the  Partnership would  have been
required to file with the Commission pursuant to Section 13 or Section 15(d)  of
the  Exchange Act if  the Partnership were  subject to such  Sections and (y) if
filing such documents by  the Partnership with the  Commission is not  permitted
under  the  Exchange  Act, promptly  upon  written  request and  payment  of the
reasonable cost of duplication and delivery, supply copies of such documents  to
any prospective Holder. (Section 1010).
 
    LIMITATIONS  ON INCURRENCE OF  INDEBTEDNESS.  The  Partnership will not, and
will not permit any  Subsidiary to, incur any  Indebtedness (as defined  below),
other  than  inter-company  debt  representing Indebtedness  to  which  the only
parties are the Company, the Partnership and any of their Subsidiaries (but only
so long  as  such  Indebtedness is  held  solely  by any  of  the  Company,  the
Partnership  and  any Subsidiary)  that is  subordinate in  right of  payment to
Outstanding  Debt  Securities  if,  immediately  after  giving  effect  to   the
incurrence  of such additional  Indebtedness, the aggregate  principal amount of
all outstanding  Indebtedness  of the  Partnership  and its  Subsidiaries  on  a
consolidated  basis  is greater  than 60%  of the  sum of  (i) Total  Assets (as
defined  below)  as  of  the  end  of  the  calendar  quarter  covered  in   the
Partnership's  Annual Report on Form  10-K or Quarterly Report  on Form 10-Q, as
the case may be, most  recently filed with the Trustee  (or such reports of  the
Company  if filed by the Partnership with the  Trustee in lieu of filing its own
reports) prior to the  incurrence of such additional  Indebtedness and (ii)  the
increase  in  Total  Assets from  the  end  of such  quarter  including, without
limitation, any increase in Total Assets  resulting from the incurrence of  such
additional  Indebtedness  (such increase,  together  with the  Total  Assets, is
referred to as "Adjusted Total Assets"). (Section 1009)
 
    In addition to the foregoing  limitation on the incurrence of  Indebtedness,
the  Partnership will  not, and  will not  permit any  Subsidiary to,  incur any
Indebtedness if the ratio of Consolidated  Income Available for Debt Service  to
the  Annual  Service  Charge  (in  each case  as  defined  below)  for  the four
consecutive fiscal quarters most recently ended prior to the date on which  such
additional Indebtedness is to be incurred shall have been less than 1.5 to 1, on
a  pro forma basis, after  giving effect to the  incurrence of such Indebtedness
and to  the  application  of  the  proceeds  therefrom  and  calculated  on  the
assumption that (i) such Indebtedness and any other Indebtedness incurred by the
Partnership  or its Subsidiaries since the first day of such four-quarter period
and the  application of  the proceeds  therefrom, including  to refinance  other
Indebtedness,  had occurred at the beginning  of such period, (ii) the repayment
or retirement of any other Indebtedness  by the Partnership or its  Subsidiaries
since the first day of such four-quarter period and had been incurred, repaid or
retired at the beginning of such period
 
                                       9
<PAGE>
(except  that, in making such computation,  the amount of Indebtedness under any
revolving credit facility shall be computed based upon the average daily balance
of such  Indebtedness  during such  period),  (iii)  the income  earned  on  any
increase  in Adjusted Total Assets since the end of such four-quarter period had
been earned on an annualized basis, during such period, and (iv) in the case  of
any acquisition or disposition by the Partnership or any Subsidiary of any asset
or  group of assets since the first  day of such four-quarter period, including,
without limitation, by  merger, stock  purchase or  sale, or  asset purchase  or
sale,  such acquisition or disposition or any related repayment Indebtedness had
occurred as of the  first day of such  period with appropriate adjustments  with
respect  to such  acquisition or  disposition being  included in  such pro forma
calculation. (Section 1009)
 
    For purposes of  the foregoing  provisions regarding the  limitation on  the
incurrence of Indebtedness, Indebtedness shall be deemed to be "incurred" by the
Partnership  or a Subsidiary  whenever the Partnership  and its Subsidiary shall
create, assume,  guarantee  or  otherwise  become  liable  in  respect  thereof.
(Section 1009)
 
    MAINTENANCE  OF  TOTAL  UNENCUMBERED  ASSETS.   For  so  long  as  there are
Outstanding any Debt  Securities (other than  Debt Securities that  are not,  by
their  terms,  entitled to  the benefit  of this  covenant), the  Partnership is
required to maintain  Total Unencumbered  Assets of not  less than  150% of  the
aggregate   outstanding   principal   amount   of   all   outstanding  Unsecured
Indebtedness. (Section 1009)
 
    As used herein:
 
        "ANNUAL SERVICE CHARGE" as of any date means the maximum amount which is
    payable in any  12-month period  from such  date for  interest and  required
    amortization   (including  amounts  payable  to  sinking  funds  or  similar
    arrangements  for  the  retirement  of  debt  which  matures  serially,  but

    of the Partnership and its Subsidiaries.
 
        "CONSOLIDATED INCOME AVAILABLE  FOR DEBT SERVICE"  for any period  means
    Consolidated  Net  Income  plus amounts  which  have been  deducted  for (a)

    (c)  amortization  of Indebtedness  discount, (d)  provisions for  gains and
    losses on properties, (e) depreciation  and amortization, (f) the effect  of
    any  noncash  charge resulting  from a  change  in accounting  principles in
    determining Consolidated Net  Income for  such period,  (g) amortization  of
    deferred  charges  and (h)  the  effect of  net  income (or  loss)  of joint
    ventures in which the Partnership or any Subsidiary owns an interest to  the
    extent not providing a source of, or requiring a use of, cash, respectively.
 
        "CONSOLIDATED   NET  INCOME"  for   any  period  means   the  amount  of
    consolidated net income (or  loss) of the  Partnership and its  Subsidiaries
    for  such  period  determined on  a  consolidated basis  in  accordance with
    generally accepted accounting principles.
 
        "INDEBTEDNESS"  of  the   Partnership  or  any   Subsidiary  means   any
    indebtedness  of the Partnership or  such Subsidiary, as applicable, whether
    or not contingent,  in respect  of (i)  borrowed money  evidenced by  bonds,
    notes,  debentures or  similar instruments,  (ii) indebtedness  secured by a
    mortgage,  pledge,  lien,  charge,  encumbrance  of  any  security  interest
    existing  on property owned by the Partnership or such Subsidiary, (iii) the
    reimbursement obligations, contingent or  otherwise, in connection with  any
    letters  of credit actually issued or  amounts representing the balance that
    constitutes an  accrued  expense or  trade  payable  or (iv)  any  lease  of
    property  by the Partnership or such Subsidiary as lessee which is reflected
    in the Partnership's consolidated  balance sheet as  a capitalized lease  in
    accordance  with generally  accepted accounting  principles, in  the case of
    items of indebtedness under (i) through  (iii) above to the extent that  any
    such items (other than letters of credit) would appear as a liability on the
    Partnership's  consolidated  balance  sheet  in  accordance  with  generally
    accepted accounting  principles,  and  also  includes,  to  the  extent  not
    otherwise  included, any obligation by the Partnership or such Subsidiary to
    be liable for, or to pay, as obligor, guarantor or otherwise (other than for
    purposes of collection in the ordinary course of business), indebtedness  of
    another person (other than the Partnership or any Subsidiary).

    other  Subsidiaries,  or  by   the  Partnership  and   one  or  more   other

    ADDITIONAL  COVENANTS.    Any  additional  or  different  covenants  of  the
Partnership with respect to any series of  Debt Securities will be set forth  in
the applicable Prospectus Supplement.
 
EVENTS OF DEFAULT
 
    Each  of  the  following  will  constitute an  Event  of  Default  under the
Indenture with respect to Debt Securities of any series: (a) failure to pay  any
interest  on any Debt Securities of that series when due, that has continued for
30 days; (b) failure to pay principal of or any premium on any Debt Security  of
that series when due; (c) failure to deposit any sinking fund payment, when due,
in respect of any Debt Security of that series; (d) failure to perform any other
covenant  of the Partnership in the Indenture (other than a covenant included in
the Indenture solely for the benefit of  a series other than that series),  that
has continued for 60 days after written notice has been given by the Trustee, or
the  Holders of at  least 25% in  aggregate principal amount  of the Outstanding
Debt Securities of that series, as provided in the Indenture; (e) failure to pay
when due  (subject  to  any  applicable  grace  period)  the  principal  of,  or
acceleration  of, any indebtedness for money borrowed by the Partnership, if, in
the case of any such failure, such  indebtedness has not been discharged or,  in
the  case of any such acceleration, such indebtedness has not been discharged or
such acceleration has  not been rescinded  or annulled, in  each case within  10
days  after written notice has  been given by the Trustee,  or the Holders of at
least 25% in aggregate  principal amount of the  Outstanding Debt Securities  of
that  series,  as  provided  in  the  Indenture,  if  the  aggregate outstanding
principal amount of indebtedness under the instrument with respect to which such
default or acceleration has occurred exceeds $10 million; (f) certain events  of
bankruptcy,  insolvency or reorganization of  the Partnership or any Significant
Subsidiary or  any of  their respective  property; and  (g) any  other event  of
default  provided  with  respect  to a  particular  series  of  Debt Securities.
(Section 501)
 
    If an Event of Default (other than  an Event of Default described in  clause
(f)  above)  with respect  to  the Debt  Securities of  any  series at  the time
Outstanding shall occur and be continuing, either the Trustee or the Holders  of
at  least 25% in  aggregate principal amount of  the Outstanding Debt Securities
 
                                       11
<PAGE>
of that series by notice as provided in the Indenture may declare the  principal
amount  of the  Debt Securities  of that  series (or,  in the  case of  any Debt
Security that  is an  Original Issue  Discount Debt  Security or  the  principal
amount  of which is not then determinable,  such portion of the principal amount
of such Debt Security, or such other amount in lieu of such principal amount, as
may be specified  in the  terms of  such Debt Security)  to be  due and  payable
immediately.  If an Event of Default described  in clause (f) above with respect
to the Debt Securities of  any series at the  time Outstanding shall occur,  the
principal  amount of all the Debt Securities of  that series (or, in the case of
any such Original  Issue Discount  Debt Security  or other  Debt Security,  such
specified  amount) will automatically, and without  any action by the Trustee or
any Holder, become immediately due and payable. After any such acceleration, but
before a judgment or decree based on acceleration, the Holders of a majority  in
aggregate  principal amount  of the Outstanding  Debt Securities  of that series
may, under certain  circumstances, rescind  and annul such  acceleration if  all
Events of Default, other than the non-payment of accelerated principal (or other
specified  amount),  have been  cured or  waived as  provided in  the Indenture.
(Section 502) For information as to waiver of defaults, see "-- Modification and
Waiver".
 
    Subject to the  provisions of the  Indenture relating to  the duties of  the
Trustee  in case an Event of Default  shall occur and be continuing, the Trustee
will be under no obligation  to exercise any of its  rights or powers under  the
Indenture at the request or direction of any of the Holders, unless such Holders
shall have offered to the Trustee reasonable indemnity. (Section 603) Subject to
such  provisions  for  the indemnification  of  the  Trustee, the  Holders  of a
majority in aggregate principal amount of the Outstanding Debt Securities of any
series will have the right  to direct the time,  method and place of  conducting
any  proceeding for any remedy available to  the Trustee or exercising any trust
or power conferred on the  Trustee with respect to  the Debt Securities of  that
series. (Section 512)
 
    No  Holder of a Debt Security of any series will have any right to institute
any proceeding  with respect  to the  Indenture,  or for  the appointment  of  a
receiver  or a  trustee, or  for any  other remedy  thereunder, unless  (i) such
Holder has previously given to the Trustee written notice of a continuing  Event
of  Default with respect to the Debt Securities of that series, (ii) the Holders
of at least 25% in aggregate principal amount of the Outstanding Debt Securities
of that  series have  made written  request,  and such  Holder or  Holders  have
offered  reasonable indemnity,  to the Trustee  to institute  such proceeding as
trustee and (iii) the Trustee has  failed to institute such proceeding, and  has
not received from the Holders of a majority in aggregate principal amount of the
Outstanding  Debt Securities of  that series a  direction inconsistent with such
request, within 60  days after  such notice,  request and  offer. (Section  507)
However,  such limitations do  not apply to a  suit instituted by  a Holder of a
Debt Security for the enforcement of payment of the principal of or any  premium
or  interest on such Debt Security on or after the applicable due date specified
in such Debt Security. (Section 508)
 
    Within 120 days after the close of each fiscal year, the Partnership will be
required to  furnish to  the Trustee  a statement  by certain  of the  Company's
officers as to whether the Partnership, to their knowledge, is in default in the
performance  or observance of any of the terms, provisions and conditions of the
Indenture and, if so, specifying all such known defaults. (Section 1004)
 
MODIFICATION AND WAIVER
 
    Modifications and amendments of the Indenture may be made by the Partnership
and the Trustee  with the  consent of  the Holders  of a  majority in  principal
amount  of  the Outstanding  Debt  Securities of  each  series affected  by such
modification or  amendment;  PROVIDED, HOWEVER,  that  no such  modification  or
amendment  may,  without the  consent  of the  Holder  of each  Outstanding Debt
Security affected thereby, (a) change the  Stated Maturity of the principal  of,
or any installment of principal of or interest on, any Debt Security, (b) reduce
the  principal amount of, or any premium  or interest on, any Debt Security, (c)
reduce the amount of  principal of an Original  Issue Discount Debt Security  or
any  other Debt Security payable upon  acceleration of the Maturity thereof, (d)
change the place  or currency  of payment  of principal  of, or  any premium  or
interest  on, any Debt Security, (e) impair  the right to institute suit for the
enforcement of any payment on or with  respect to any Debt Security, (f)  reduce
the percentage in principal amount of Outstanding Debt Securities of any series,
the  consent of whose Holders  is required for modification  or amendment of the
Indenture,   (g)    reduce   the    percentage    in   principal    amount    of
 
                                       12
<PAGE>
Outstanding  Debt Securities  of any series  necessary for  waiver of compliance
with certain provisions of  the Indenture or for  waiver of certain defaults  or
(h)  modify such  provisions with respect  to modification  and waiver. (Section
902)
 
    The Holders  of a  majority  in principal  amount  of the  Outstanding  Debt
Securities  of any series  may waive compliance by  the Partnership with certain
restrictive provisions  of  the  Indenture.  (Section 1011)  The  Holders  of  a
majority  in principal amount  of the Outstanding Debt  Securities of any series
may waive any past default under the Indenture, except a default in the  payment
of  principal, premium or  interest and certain covenants  and provisions of the
Indenture that  cannot be  amended without  the consent  of the  Holder of  each
Outstanding Debt Security of such series affected. (Section 513)
 
    The  Indenture  provides  that in  determining  whether the  Holders  of the
requisite principal  amount of  the Outstanding  Debt Securities  have given  or
taken any direction, notice, consent, waiver or other action under the Indenture
as  of any  date (i)  the principal  amount of  an Original  Issue Discount Debt
Security that  will be  deemed  to be  Outstanding will  be  the amount  of  the
principal  thereof  that  would  be  due  and  payable  as  of  such  date  upon
acceleration of the Maturity thereof to such date and (ii) if, as of such  date,
the  principal amount payable at  the Stated Maturity of  a Debt Security is not
determinable (for  example, because  it is  based on  an index),  the  principal
amount of such Debt Security deemed to be Outstanding as of such date will be an
amount  determined in the manner prescribed for such Debt Security. Certain Debt
Securities, including  those for  whose  payment or  redemption money  has  been
deposited  or set aside in trust for the  Holders and those that have been fully
defeased pursuant  to  Section 1302,  will  not  be deemed  to  be  Outstanding.
(Section 101)
 
    Except in certain limited circumstances, the Partnership will be entitled to
set  any day  as a  record date for  the purpose  of determining  the Holders of
Outstanding Debt  Securities  of  any  series  entitled  to  give  or  take  any
direction,  notice, consent, waiver or other  action under the Indenture, in the
manner and subject  to the  limitations provided  in the  Indenture. In  certain
limited  circumstances, the Trustee  will be entitled  to set a  record date for
action by Holders. If a record date is set for any action to be taken by Holders
of a particular series, such action may be taken only by persons who are Holders
of Outstanding  Debt  Securities  of that  series  on  the record  date.  To  be
effective,  such  action must  be taken  by Holders  of the  requisite principal
amount of such Debt  Securities within a specified  period following the  record
date.  For any  particular record  date, this  period will  be 180  days or such
shorter period as may be specified by the Partnership (or the Trustee, if it set
the record date), and may be shortened  or lengthened (but not beyond 180  days)
from time to time. (Section 104)
 
    Modifications and amendments of the Indenture may be made by the Partnership
and the Trustee without the consent of any holders of Debt Securities for any of
the  following purposes: (i) to evidence the succession of another person to the
Partnership and  the  assumption by  such  successor  of the  covenants  of  the
Partnership  in  the Indenture  and  the Debt  Securities;  (ii) to  add  to the
covenants of the Partnership for the benefit of the holders of all or any series
of Debt  Securities  or to  surrender  any right  or  power conferred  upon  the
Partnership  in the Indenture; (iii) to add events of default for the benefit of
the holders of all or  any series of Debt Securities;  (iv) to add to or  change
any  provisions  of  the Indenture  as  necessary  to permit  or  facilitate the
issuance of Debt  Securities in uncertificated  form; (v) to  add to, change  or
eliminate  any of the  provisions of the  Indenture with respect  to one or more
series of Debt Securities, so  long as the changes (A)  do not (1) apply to  any
Debt  Securities of any  series created prior to  such modification or amendment
and entitled to the benefit  of such provision or (2)  modify the rights of  the
holder  of any such  Debt Security with  respect to such  provision, or (B) will
only become effective when there is  no such Debt Security Outstanding; (vi)  to
secure  the  Debt Securities;  (vii)  to establish  the  form or  terms  of Debt
Securities of any series as permitted in the Indenture; or (viii) to provide for
the acceptance of appointment by a successor Trustee. (Section 901)

DEFEASANCE AND COVENANT DEFEASANCE
 
    If and to the extent indicated in the applicable Prospectus Supplement,  the
Partnership  may elect,  at its option  at any  time, to have  the provisions of
Section  1302  of  the  Indenture,  relating  to  defeasance  and  discharge  of
indebtedness,  or Section  1303, relating  to defeasance  of certain restrictive
covenants in the Indenture, applied to the Debt Securities of any series, or  to
any specified part of a series. (Section 1301)
 
    DEFEASANCE   AND  DISCHARGE.     The  Indenture  provides   that,  upon  the
Partnership's exercise of its  option (if any) to  have Section 1302 applied  to
any Debt Securities, the Partnership will be discharged from all its obligations
with respect to such Debt Securities (except for certain obligations to exchange
or  register  the  transfer  of  Debt Securities,  to  replace  stolen,  lost or
mutilated Debt Securities, to  maintain paying agencies and  to hold moneys  for
payment  in trust) upon the  deposit in trust for the  benefit of the Holders of
such Debt Securities of  money or U.S. Government  Obligations, or both,  which,
through  the payment of principal and  interest in respect thereof in accordance
with their  terms,  will  provide money  in  an  amount sufficient  to  pay  the
principal  of  and any  premium  and interest  on  such Debt  Securities  on the
respective Stated Maturities in accordance with  the terms of the Indenture  and
such  Debt Securities.  Such defeasance  or discharge  may occur  only if, among
other things, the Partnership has delivered to the Trustee an Opinion of Counsel
to the  effect  that  the Partnership  has  received  from, or  there  has  been
published  by, the United States Internal Revenue Service a ruling, or there has
been a change in tax law, in either case to the effect that Holders of such Debt
Securities will not recognize gain or loss for federal income tax purposes as  a
result  of such deposit, defeasance and discharge and will be subject to federal
income tax on the same amount, in the same manner and at the same times as would
have been the case if such deposit, defeasance and discharge were not to  occur.
(Sections 1302 and 1304)
 
    DEFEASANCE  OF CERTAIN  COVENANTS.   The Indenture  provides that,  upon the
Partnership's exercise of its  option (if any) to  have Section 1303 applied  to
any Debt Securities, the Partnership may omit to comply with certain restrictive
covenants,  including  those described  under "Certain  Covenants," in  the last
sentence under "Merger, Consolidation or Sale" and any that may be described  in
the  applicable Prospectus Supplement,  and the occurrence  of certain Events of
Default, which  are  described  above  in  clause  (d)  (with  respect  to  such
restrictive covenants) and clauses (e) and (g) under "Events of Default" and any
that  may be described  in the applicable Prospectus  Supplement, will be deemed
not to be or result in  an Event of Default, in  each case with respect to  such
Debt  Securities. The  Partnership, in  order to  exercise such  option, will be
required to  deposit, in  trust for  the benefit  of the  Holders of  such  Debt
Securities,  money or U.S.  Government Obligations, or  both, which, through the
payment of principal and  interest in respect thereof  in accordance with  their
terms,  will provide money in  an amount sufficient to  pay the principal of and
any premium  and interest  on  such Debt  Securities  on the  respective  Stated
Maturities  in  accordance  with  the  terms  of  the  Indenture  and  such Debt
Securities. The  Partnership  will also  be  required, among  other  things,  to
deliver  to the Trustee an Opinion of Counsel to the effect that Holders of such
Debt Securities will not recognize gain or loss for federal income tax  purposes
as  a result of such  deposit and defeasance of  certain obligations and will be
subject to federal income tax on the same amount, in the same manner and at  the
same  times as would have been the case  if such deposit and defeasance were not
to occur. In the event the Partnership exercised this option with respect to any
Debt Securities and such Debt Securities  were declared due and payable  because
of  the  occurrence  of any  Event  of Default,  the  amount of  money  and U.S.
Government Obligations so deposited in trust would be sufficient to pay  amounts
due  on such Debt Securities  at the time of  their respective Stated Maturities
but may not be sufficient  to pay amounts due on  such Debt Securities upon  any
acceleration resulting from such Event of Default. In such case, the Partnership
would remain liable for such payments. (Sections 1303 and 1304) "U.S. Government
Obligations"  means securities  which are (i)  direct obligations  of the United
States of America for the payment of which its full faith and credit is  pledged
or  (ii) obligations  of a person  controlled or  supervised by and  acting as a
agency or instrumentality of the United States of America, the payment of  which
is  unconditionally  guaranteed as  a full  faith and  credit obligation  by the
United States of America, which, in either case, are not callable or  redeemable
at the option of the issuer thereof, and shall also include a depository receipt
issued  by a bank  or trust company as  custodian with respect  to any such U.S.
Government Obligation or a specific payment  of interest on or principal of  any
such  U.S.  Government  Obligation held  by  such  custodian of  the  account of
 
                                       14
<PAGE>
the holder of a  depository receipt, provided that  (except as required by  law)
such  custodian is not authorized to make  any deduction from the amount payable
to the  holder  of such  depository  receipt from  any  amount received  by  the
custodian  in respect of the U.S.  Government Obligation or the specific payment
of interest on or principal of the U.S. Government Obligation evidenced by  such
depository receipt. (Section 1304)
 
NOTICES
 
    Notices to Holders of Debt Securities will be given by mail to the addresses
of  such Holders as they may appear  in the Security Register. (Sections 101 and
106)
 
TITLE
 
    The Partnership, the Trustee and any agent of the Partnership or the Trustee
may treat the Person in whose name a Debt Security is registered as the absolute
owner thereof (whether or not such Debt Security may be overdue) for the purpose
of making payment and for all other purposes. (Section 308)
 
NO CONVERSION RIGHTS
 
    The Debt Securities  will not be  convertible into or  exchangeable for  any
capital stock of the Company or equity interest in the Partnership.
 
                              PLAN OF DISTRIBUTION
 
    The Partnership may sell Debt Securities to or through underwriters and also
may sell Debt Securities directly to other purchasers or through agents.
 
    The distribution of the Debt 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
market  prices  prevailing  at the  time  of  sale, at  prices  related  to such
prevailing market prices or at negotiated prices.
 
    In connection with  the sale  of Debt Securities,  underwriters may  receive
compensation from the Partnership or from purchasers of Debt Securities for whom
they  may act as  agents in the  form of discounts,  concessions or commissions.
Underwriters may sell Debt  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  agents.  Underwriters,  dealers  and  agents  that  participate  in the
distribution of  Debt Securities  may  be deemed  to  be underwriters,  and  any
discounts or commissions received by them from the Partnership and any profit on
the resale of Debt Securities by them may be deemed to be underwriting discounts
and  commissions,  under  the  Securities  Act of  1933  (the  "Act").  Any such
underwriter or agent will be identified, and any such compensation received from
the Partnership will be described, in the Prospectus Supplement.
 
    Under agreements which may be entered into by the Partnership,  underwriters
and  agents  who  participate in  the  distribution  of Debt  Securities  may be
entitled to  indemnification by  the  Partnership against  certain  liabilities,
including liabilities under the Act.
 
    Certain of the underwriters and their affiliates may be customers of, engage
in  transactions with, and perform services for, the Company and the Partnership
in the ordinary course of business.
 
                          VALIDITY OF DEBT SECURITIES
 
    The validity of the Debt Securities will be passed upon for the  Partnership
by Hunton & Williams, Richmond, Virginia.

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS
 
    The   following  discussion  and  analysis  of  the  consolidated  financial
condition and results of  operations of SUSA  Partnership, L.P. (the  "Operating
Partnership")  should  be read  in conjunction  with the  Consolidated Financial
Statements and Notes  thereto. References to  the Operating Partnership  include
SUSA  Management,  Inc., a  wholly owned  subsidiary.  Storage USA,  Inc., ("the
Company") a  self-managed real  estate  investment trust  ("REIT") is  the  sole
general partner of the Operating Partnership.
 
    Due  to the substantial number of facilities acquired from March 31, 1995 to
March 31,  1996, management  believes  that it  is  meaningful and  relevant  in
understanding the present and ongoing operations of the Operating Partnership to
compare certain information using occupancy, per square foot and pro forma data.
 
    The  following are definitions  of terms used  throughout this discussion in
analyzing the Operating Partnership's business. PHYSICAL OCCUPANCY is defined as
the total net rentable square feet rented as of the date computed divided by the
total net rentable square feet available.  GROSS POTENTIAL INCOME is defined  as
the  sum of all units  available to rent at a  facility multiplied by the market
rental rate applicable to those units  as of the date computed. EXPECTED  INCOME
is  defined as the sum of the monthly rent being charged for the rented units at
a facility  as  of the  date  computed. ECONOMIC  OCCUPANCY  is defined  as  the
Expected  Income divided by the Gross Potential  Income. RENT PER SQUARE FOOT is
defined as the annualized result of dividing Gross Potential Income on the  date
computed  by total net rentable square feet available. DIRECT PROPERTY OPERATING
COST is defined as the  costs incurred in the operation  of a facility, such  as
utilities,   real  estate  taxes,  and   on-site  personnel.  INDIRECT  PROPERTY
OPERATIONS  COST  is  defined  as  costs  incurred  in  the  management  of  all
facilities,  such  as  accounting  personnel  and  management  level  operations
personnel. NET OPERATING INCOME  ("NOI") is defined  as total property  revenues
less Direct Property Operating Costs.
 
RESULTS OF OPERATIONS -- QUARTER ENDED MARCH 31, 1996 COMPARED TO QUARTER ENDED
MARCH 31, 1995
 
    In  the first quarter of 1996,  the Operating Partnership reported growth in
revenue, income from  property operations  and net income,  respectively, of  $9
million,  $5.7 million  and $2.9  million over the  same quarter  of 1995. Since
March  31,1995,  the  Operating  Partnership  has  acquired  67  facilities  and
completed  construction and opened  one new facility.  These 68 facilities added
47,620 units, and 4.7  million square feet, bringing  the total square feet  and
units of the 166 facilities owned by the Operating Partnership at March 31, 1996
to  11.1  million square  feet and  110,010 units,  respectively. For  the first
quarter of  1996, the  98 facilities  owned during  the first  quarter of  1995,
provided   59%  of  the  Operating   Partnership's  rental  income.  These  same
facilities' rental income grew 7.2% over  1995 results. Most of this growth  was
provided  by  rate  increases. At  March  31,  1996, the  physical  and economic
occupancy and rent per square foot on these facilities were 88%, 81%, and $9.61,
respectively, while the figures for the same period ended in 1995 were 87%, 79%,
and $8.93, respectively. The  Operating Partnership's portfolio  as a whole  had
average  occupancy at March 31,  1996 of 88% physical  and 81% economic, with an
average rent per square foot of  $9.40. Management income for the quarter  ended
March  31, 1996  remained relatively  consistent with  the comparable  period in
1995. Other  income,  which  reflects  primarily sales  of  lock  and  packaging
products and truck rentals, increased primarily due to property acquisitions.
 
    Cost of property operations and maintenance was $5.7 million for the quarter
ended  March  31, 1996,  representing  a $2.4  million  increase over  the first
quarter of 1995. Cost of property operations and maintenance was 27% of revenues
for both the quarter ended  March 31, 1996 and for  the quarter ended March  31,
1995.
 
    Real  estate tax expense increased from $.8 million or 6.5 % of revenues for
the quarter ended  March 31, 1995  to $1.7 million  or 7.9% of  revenue for  the
quarter  ended March 31, 1996.  This growth as a  percentage of revenue reflects
the  impact  of   reassessments  on   the  properties   purchased  during   1994
 
                                      F-3
<PAGE>
and  1995.  The majority  of the  increase is  attributable to  reassessments on
acquisitions  with  the  remainder  attributable  to  increased  tax  rates   or
reassessments  on properties  owned for a  full year.  The Operating Partnership
expects real estate tax expense as a percentage of revenues for the remainder of
1996 to remain consistent with the first quarter.
 
    General and administrative  expense increased $0.3  million to $0.8  million
for  the  first  quarter of  1996  from the  comparable  quarter of  1995.  As a
percentage of revenues the  expense fell from 4.2%  for the quarter ended  March
31, 1995 to 3.6% for the quarter ended March 31, 1996. The Operating Partnership
expects  that the  expense will  decline further as  a percentage  of revenue in
1996, while the gross expense will grow as the Operating Partnership expands its
accounting, management information systems,  and human resource departments,  in
connection with its ongoing growth strategy.
 
    Depreciation  expense increased to $2.7 million  for the quarter ended March
31, 1996 from  $1.6 million for  the comparable period  in 1995, reflecting  the
increase  in  the  number of  facilities  owned. The  Operating  Partnership has
acquired approximately $179 million in depreciable assets since April 1, 1995.
 
    Interest expense for the  quarter ended March 31,  1996 was $1.7 million  as
compared  to  $0.2 million  for  the comparable  period  in 1995.  1996 interest
expense represents  weighted  average  borrowings  of  $106  million  under  the
Operating  Partnership's lines of credit at  a weighted average interest rate of
6.1%.
 
    Interest income was $0.15  million for the quarter  ended March 31, 1996  as
compared  to $0.01 million for  the quarter ended March  31, 1995. 1996 interest
income represents earnings on overnight deposits and amounts contributed by  the
Company  from earnings under the Company's 1995 Employee Stock Purchase and Loan
Plan.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    Cash provided from  operations grew to  $10.9 million for  the three  months
ended  March 31,  1996 from $5.9  million for  the three months  ended March 31,
1995. This  increase is  a  result of  the  Operating Partnership's  net  income
growing  $2.9 million or 48% primarily as a  result of the increase in number of
facilities owned, and the improvement  of operations at the facilities  acquired
plus depreciation and amortization of $2.7 million.
 
    The  Operating Partnership's first quarter investing activities consisted of
six facility  acquisitions  for  approximately $22  million.  In  addition,  the
Operating  Partnership acquired three parcels of land for $2.2 million to permit
expansion of two facilities and the construction of a new self-storage facility.
Three new  property constructions  are  underway at  an  estimated cost  of  $11
million.  Completion dates range from the second quarter of 1996 through 1997. A
total of 15 expansion projects are in  process with an estimated cost of $12  to
$13  million  with openings  scheduled for  late 1996  into 1997.  The Operating
Partnership currently plans to  the develop 11 new  facilities primarily in  the
Washington,  D.C. and Memphis, TN  metropolitan areas. The Operating Partnership
expects that the cost of the land, the facility construction costs and the  soft
costs, such as capitalized interest, will total approximately $42 million. These
contracts  are subject to zoning approvals and other contingencies, and assuming
successful  completion  of  the   development  and  construction  process,   the
properties are expected to open during 1997 and 1998.
 
    On  March 1, 1996, the Company entered  into a Stock Purchase Agreement with
Security Capital U.S.  Realty ("US  Realty"), an affiliate  of Security  Capital
Group.  Under  the  Stock Purchase  Agreement,  and  pursuant to  the  terms and
conditions thereof,  US  Realty will  invest  a total  of  $220 million  in  the
Company,  initially  place  two  of  its  nominees  on  the  Company's  Board of
Directors, one of whom the Company has been informed will be William D. Sanders,
Chairman of the Board and Chief Executive Officer of Security Capital Group, and
make available to  the Company  certain strategic advice,  research and  related
information   and  expertise  (the   "Strategic  Alliance").  As   part  of  the
transaction, on March 19, 1996, the Company issued to US Realty 1,948,882 shares
of Common Stock, approximately 10.0% of the outstanding Common Stock, at a price
of $31.30 per share, plus a purchase price adjustment for accrued dividends.  At
the  same  time,  the Company  executed  a  Strategic Alliance  Agreement  and a
 
                                      F-4
<PAGE>
Registration Rights  Agreement  with  US Realty.  The  Company  contributed  the
proceeds  of the offering to the  Operating Partnership, which used the proceeds
to pay off $43.4 million of borrowings under the available lines of credit,  for
property acquisitions, and for working capital.
 
    At March 31, 1996, the Operating Partnership had $64.2 million of borrowings
outstanding  on its line of credit, $3.4  million of fixed rate debt maturing in
2001, $2.3 million  of fixed rate  debt maturing  in 2006, and  $0.9 million  of
fixed rate debt maturing in 2000. The Operating Partnership had $40.8 million of
unused borrowing capacity under its lines of credit at March 31, 1996.
 
    During  the quarter,  the Operating Partnership  issued approximately 48,000
units of limited partnership  interest valued at  approximately $1.5 million  in
connection  with  the  acquisition of  facilities.  The  Operating Partnership's
acquisition  of  self-storage  facilities  using  Units  as  consideration   may
partially defer the seller's tax liability.
 
    The  Operating  Partnership has  entered  into various  property acquisition
contracts for facilities with an aggregate cost of approximately $55.8  million.
These  acquisitions are  subject to  customary conditions  to closing, including
satisfactory due diligence and  should close during  the second quarter.  Should
these  contracts be disapproved, the costs incurred by the Operating Partnership
would be immaterial.
 
    On April  10, 1996,  the Operating  Partnership filed  a shelf  registration
statement  relating to  $250 million  of unsecured  non convertible  senior debt
securities which should enable  the Operating Partnership  to access the  public
debt markets efficiently at opportune times.
 
FUNDS FROM OPERATIONS ("FFO")
 
    The  Operating  Partnership  believes  that  FFO  should  be  considered  in
conjunction  with  its  net  income  and  cash  flows  to  facilitate  a   clear
understanding  of  its results  of  operations. FFO  is  defined as  net income,
computed  in  accordance   with  GAAP,  excluding   gains  (losses)  from   debt
restructuring  and sales  of property,  plus depreciation  and amortization, and
after adjustments for unconsolidated partnerships and joint ventures. FFO should
not be considered an  alternative to net  income as a  measure of the  Company's
performance or to cash flows as a measure of liquidity.
 
    Effective   January  1,  1996,  the  National  Association  of  Real  Estate
Investment Trusts amended its definition of FFO. The impact of conforming to the
amended definition was to reduce FFO  by approximately $104,000 and $50,000  for
the  three months ended March 31, 1996 and March 31, 1995, respectively. Because
certain REITs may have  not yet adopted the  amended method of FFO  computation,
the  Company's FFO and FFO  per share may not  be comparable to similarly titled
measures of other REITs.
 
    The  following   table  illustrates   the   components  of   the   Operating
Partnership's FFO for the quarters ended March 31, 1996 and March 31, 1995.

</TABLE>
 
    The  Company, in  order to qualify  as a  REIT, is required  to distribute a
substantial portion of its net income as dividends to its shareholders. For  the
year  ended December 31, 1995, those distributions were approximately 85% of the
Company's FFO.  It  is  the  intent  of  the  Operating  Partnership  that  cash
distributions  will be made for  each fiscal year to  enable the Company to meet
its distribution requirements for qualification  as a REIT. While the  Operating
Partnership's goal is to generate and retain
 
                                      F-5
<PAGE>
sufficient cash flow to meet its operating, capital, and debt service needs, its
dividend  requirements may require the Operating Partnership to utilize its bank
lines of  credit to  finance  property acquisitions  and development  and  major
capital improvements.
 
    The  Operating  Partnership  has  incurred  approximately  $0.2  million for
regularly scheduled maintenance and repairs during the three months ended  March
31, 1996. For the year, the Operating Partnership expects to incur approximately
$1.2  million  for  scheduled  maintenance and  repairs  and  approximately $5.9
million to  conform  facilities  acquired  during 1995  and  1994  to  Operating
Partnership standards.
 
    The  Operating Partnership believes that its liquidity and capital resources
are adequate to meet its cash  requirements relating to its existing  operations
for the next twelve months.
 
INFLATION
 
    The  Operating Partnership does  not believe that inflation  has had or will
have a direct effect on its operations.  Substantially all of the leases at  the
facilities  allow for monthly increases  which provide the Operating Partnership
with the  opportunity  to achieve  increases  in  rental income  as  each  lease
matures.
 
SEASONALITY
 
    The Operating Partnership's revenues typically have been higher in the third
and  fourth quarter  primarily because  the Operating  Partnership increases its
rental rates on  most of its  storage units at  the beginning of  May, and to  a
lesser  extent  because  self-storage  facilities  tend  to  experience  greater
occupancy during  the late  spring and  early  fall months  due to  the  greater
incidence  of residential moves during  those periods. The Operating Partnership
believes that its tenant  mix, rental structure,  and expense structure  provide
adequate  protection against undue  fluctuations in cash  flows and net revenues
during off-peak  seasons.  Thus,  the  Operating  Partnership  does  not  expect
seasonality to materially affect distributions to shareholders.
 
RECENT ACCOUNTING DEVELOPMENTS
 
    In  October of  1995, Statement of  Financial Accounting  Standards No. 123,
"Accounting for Stock-Based Compensation" ("FAS  123") was issued. The  standard
is  effective for fiscal years beginning  after December 15, 1995. The Operating
Partnership has  continued  to  elect  expense recognition  under  APB  25,  and
disclosing pro forma net income, and earnings per share information based on the
FAS123 fair value methodology.

1.  UNAUDITED INTERIM FINANCIAL STATEMENTS
 
    Interim  consolidated financial  statements of  SUSA Partnership,  L.P. (The
"Operating Partnership") are prepared pursuant to the requirements for reporting
on Form  10-Q. Accordingly,  certain disclosures  accompanying annual  financial
statements  prepared in accordance with generally accepted accounting principles
are omitted. In the opinion of management, all adjustments, consisting solely of
normal  recurring   adjustments,  necessary   for  the   fair  presentation   of
consolidated  financial statements for  the interim periods  have been included.
The current period's  results of  operations are not  necessarily indicative  of
results  which ultimately may be achieved for the year. The interim consolidated
financial statements and notes  thereto should be read  in conjunction with  the
financial  statements and notes thereto included  in the Company's Form 10-K, as
filed with the Securities and Exchange Commission.
 
2.  ORGANIZATION
 
    The Operating Partnership, which commenced  operation on March 23, 1994,  is
engaged   in  owning,   developing,  constructing   and  operating  self-storage
facilities throughout  the  United  States.  The sole  general  partner  in  the
Operating   Partnership,  Storage   USA,  Inc.  (the   "Company"),  a  Tennessee
corporation, is  a self-administered  and  self-managed real  estate  investment
trust ("REIT").
 
    On  March 23,  1994, the  Company contributed  substantially all  of its net
assets of approximately $109,969 to the Operating Partnership in exchange for an
approximately 98.9% general partnership  interest in the Operating  Partnership.
In  addition,  the Operating  Partnership formed  SUSA Management,  Inc., ("SUSA
Management") to provide  self-storage management  to third  parties and  certain
ancillary  services. The Operating Partnership owns 99% of the economic interest
of SUSA Management.
 
3.  PARTNERSHIP CAPITAL
 
                        FORMATION OF STRATEGIC ALLIANCE
 
    On March 1, 1996, the Company, as corporate general partner, entered into  a
Stock  Purchase  Agreement  with  Security Capital  U.S.Realty  (US  Realty), an
affiliate of Security Capital Group. Under the Stock Purchase Agreement, subject
to the terms and conditions thereof, US  Realty will invest a total of  $220,000
in  the Company, initially place  two of its nominees  on the Company's Board of
Directors, one of whom the Company has been informed will be William D. Sanders,
Chairman of the Board and Chief Executive Officer of Security Capital Group, and
make available to  the Company  certain strategic advice,  research and  related
information   and  expertise  (the   "Strategic  Alliance").  As   part  of  the
transaction, on March 19, 1996, the Company issued to US Realty 1,948,882 shares
of Common Stock, approximately 10.0% of the outstanding Common Stock, at a price
of $31.30 per share, plus a purchase price adjustment for accrued dividends less
issuance costs. At  the same  time, the  Company executed  a Strategic  Alliance
Agreement and a Registration Rights Agreement with US Realty.
 
    After  the Strategic Alliance  has been approved by  the shareholders of the
Company, and prior to December 31, 1996, the Company will issue to US Realty  an
additional  5,079,872 shares of the Company's common stock at the same price for
an aggregate of $159,000. After acquiring the additional shares (and assuming no
other  change  in  the  number  of  outstanding  shares)  US  Realty  will   own
approximately  28.6% of the outstanding Common Stock. The proceeds of additional
fundings will  be  contributed to  the  Operating Partnership  in  exchange  for
additional  Operating Partnership Units and used  to support the acquisition and
development of self-storage facilities.
 
    The Company has agreed to submit to the shareholders a proposal to amend the
ownership limitations of the Company's Charter to permit US Realty to acquire up
to 37.5% of the Company's capital  stock. The Strategic Alliance, the  amendment
and  certain  related  transactions  have  been  submitted  to  shareholders for
approval at the Company's 1995 annual meeting to be held June 5, 1996.

3.  PARTNERSHIP CAPITAL (CONTINUED)
                     EMPLOYEE STOCK PURCHASE AND LOAN PLAN
 
    The Company  established the  1995 Employee  Stock Purchase  and Loan  Plan.
Under  the terms of the partnership agreement, all proceeds from the issuance of
common stock under  the plan  are contributed  to the  Operating Partnership  in
exchange  for Operating Partnership units. In  March of 1996, the Company issued
40,000 shares of its common stock under  the plan. Pursuant to the terms of  the
plan,  the Company and  certain officers entered  into stock purchase agreements
whereby the officers purchased common stock at the then current stock price. The
Company provides 100% financing for the purchase of the shares with interest  at
7%  per annum payable quarterly. The underlying  notes are secured by the shares
and mature  in  November 2002.  At  March 31,  1996,  there are  270,000  shares
outstanding under the plan.

5.  LINE OF CREDIT BORROWINGS
 
    Line of  credit  borrowings  at  March  31,  1996  consists  of  $64,165  of
borrowings under a $75,000 line of credit with a group of commercial banks. This
line  bears interest at various spreads over  a base rate based on the Operating
Partnership's debt  service coverage.  During  the first  quarter of  1996,  the
weighted  average borrowing was $105,540, and the weighted average interest rate
was 6.1%. The Operating Partnership also has a line of credit with a  commercial
bank which bears interest at Prime or

mortgages collateralizing the line and  increase the amount available under  the
line from $23 million to $30 million, with an initial maturity of July 1, 1996.
 
6.  INTEREST RATE SWAP AGREEMENT
 
    In  anticipation  of  a debt  offering  in 1996,  the  Operating Partnership
entered into an interest rate swap agreement in October 1995, with the objective
of reducing its  exposure to  future interest rate  fluctuations. The  agreement
involved  the exchange  of a  variable rate  for a  fixed rate  interest payment
obligation. On March 8, 1996, the Operating Partnership closed the interest rate
swap agreement  and  received  proceeds  of  approximately  $50.  The  Operating
Partnership  filed a $250,000 debt shelf registration statement on Form S-3 with
the Securities  and  Exchange Commission  on  April 10,  1996.  Upon  successful
completion  of an  offering of  unsecured debt  securities under  the shelf, the
Operating Partnership will  recognize the gain  as a yield  adjustment over  the
life of the debt.
 
7.  COMMITMENTS AND CONTINGENCIES
 
  PROPERTY DEVELOPMENT
 
    The  Operating  Partnership  has  entered into  an  agreement  to  develop a
self-storage facility in Northern  Virginia. The facility will  be owned by  the
Operating  Partnership and an  unaffiliated third party. Under  the terms of the
agreement  the  Operating  Partnership   is  required  to   fund  the  cost   of
construction,  which is  currently estimated to  be approximately  $6,500. As of
March 31, 1996, the  Operating Partnership has  incurred costs of  approximately
$4,183. The facility is expected to be complete by the second quarter of 1996.
 
8.  SUBSEQUENT EVENTS
 
    Subsequent  to March 31,  1996, the Operating  Partnership has completed the
acquisition of  five self-storage  facilities for  approximately $16,000.  These
acquisitions were financed through operating cash flows and borrowings under the
available  line of  credit. The Operating  Partnership has  entered into various
property acquisition contracts with an aggregate cost of approximately  $55,800.
These  acquisitions are  subject to  customary conditions  to closing, including
satisfactory due diligence and  should close during  the second quarter.  Should
these  contracts be disapproved, the costs incurred by the Operating Partnership
would be immaterial.

condition and results of  operations of SUSA  Partnership, L.P. (the  "Operating
Partnership")  should  be read  in conjunction  with the  Consolidated Financial
Statements and Notes  thereto. Storage  USA, Inc.  (the "Company")  is the  sole
general  partner  in  the  Operating  Partnership  and  is  a self-administered,
self-managed real estate investment  trust ("REIT"). As discussed  in Note 1  to
the  Consolidated Financial Statements, the Operating Partnership's 1994 results
of operations  are  presented  from  March 24,  1994,  the  date  the  Operating
Partnership  commenced operation.  As discussed in  Note 11  to the Consolidated
Financial Statements,  the accompanying  combined financial  statements for  the
periods  prior to  March 24,  1994, present  only the  "carved out"  accounts of
Storage  USA,  Inc.  (the  "Predecessor")  comprised  of  the  combined  assets,
liabilities,  and operations of the Predecessor  preceding the IPO, including 11
owned facilities and 6  controlled facilities and  Storage USA Management  Corp.
The  Predecessor completed its initial public  offering (the "IPO") on March 23,
1994, forming  the Company  and  the Operating  Partnership. References  to  the
"Operating   Partnership"  include   SUSA  Management,  Inc.,   a  wholly  owned
subsidiary.
 
    Due to the substantial number of  facilities acquired during 1995 and  1994,
management  believes that  it is  meaningful and  relevant in  understanding the
present  and  ongoing  operations  of  the  Operating  Partnership  to   compare
information using occupancy, per square foot and pro forma data. The assumptions
underlying  the pro forma data presented  are described under "Pro Forma Results
of Operations for the period January 1, 1994 through December 31, 1994."
 
OVERVIEW:
 
    In 1995,  the  Operating Partnership  continued  executing its  strategy  of
acquiring  suitably  located,  under-performing  facilities  that  offer  upside
potential due to low  occupancy rates or non-premium  pricing. During the  year,
the  Operating Partnership invested $220 million  in acquiring 63 facilities. In
addition,  the  Operating  Partnership  pursued  development  opportunities   in
selective markets, specifically the San Francisco, Memphis, and Washington, D.C.
areas.  The Operating Partnership invested $4.7  million in acquiring 11 parcels
of land for expansion of existing facilities and $0.8 million acquiring a parcel
of land  to be  developed. The  1995 financial  results reflect  the  continuing
implementation of this acquisition and development strategy.
 
    Contributions  to  the  Operating  Partnership's  revenue  growth  came from
successful execution  of  both  external and  internal  growth  strategies.  The
Operating  Partnership continues to  purchase properties on  an accretive basis.
Internal growth remained strong during 1995. The 96 properties owned at December
31, 1994 demonstrated total revenue growth of  7.4% and NOI growth of 4.7%  over
the  pro forma 1994 results. The lower rate of NOI growth reflects the fact that
the pro forma expense is based on the previous operator's expense structure  for
the  period  prior  to  acquisition,  and  the  Operating  Partnership's expense
structure is generally higher than that of the previous operator. The  Operating
Partnership  expects that  when comparing its  actual "same  store" results, NOI
growth will  generally exceed  revenue growth,  similarly to  the 67  facilities
described  herein. The Operating Partnership considers facilities to be suitable
for a year-over-year  results comparison  only after four  complete quarters  of
operation by the Operating Partnership. For example, if a facility was purchased
in  January of 1995, the Operating Partnership  would consider it suitable for a
year-over-year comparison  beginning with  the second  quarter of  1996. The  67
properties  owned by the Operating Partnership  for the entire fourth quarter of
1994, experienced 5.2% rental income growth  and 7.7% NOI growth for the  fourth
quarter  of  1995  over the  same  quarter  in 1994.  The  Operating Partnership
believes that once it implements its property operations expense structure,  its
Direct  Property Operations Costs should increase on a year-over-year basis in a
more predictable pattern.
 
                                      F-14

    In 1995, the  Operating Partnership experienced  cost growth principally  in
the  areas  of  real  estate  tax and  Indirect  Property  Operations  Cost. The
Operating Partnership's cost  to manage, or  Indirect Property Operations  Cost,
grew during 1995 to a year-end result of $3.2 million or 4.7% of total revenues.
This  was a result  of the Operating Partnership's  planning and structuring for
continued growth. The Operating Partnership  added four district offices  during
the  year, and  added regional  coordinators and  trainers at  each of  its four
regional offices. The  personnel additions  allow the  Operating Partnership  to
shift  to the regional offices certain  duties that were previously performed at
the Partnership's home office. During the fourth quarter of 1995, the  Operating
Partnership  began to experience growth  in property tax expense  as a result of
revised assessments on acquired facilities. In the initial period following  the
Operating  Partnership's purchase  of a  facility, the  Operating Partnership is
subject to reassessments which may result  in increased real estate tax  expense
for  the  facility.  While  these  increases  are  estimated  by  the  Operating
Partnership in  underwriting the  acquisitions  of the  facility, they  may  not
actually  be incurred by the Operating  Partnership until generally 12-24 months
after closing. In the periods that follow the initial reassessment, increases in
property tax expense becomes more predictable.
 
    The Operating Partnership  expects to continue  implementing its  strategies
for  growth in 1996. The  addition of Indirect Property  Operations Cost in 1995
will allow the  Operating Partnership  capacity to  add more  facilities in  the
future,  assuming  an  even  distribution of  the  facilities  in  the Operating
Partnership's  existing  markets.  Acquisitions  continue  to  be  available  at
attractive capitalization rates and at prices that approximate replacement cost.
Development  efforts  will intensify  in  1996, with  the  Operating Partnership
planning to  have  500,000  square  feet under  development  during  1996.  This
development   includes  expansion  of   existing  facilities  as   well  as  new
construction. The  Operating  Partnership  considers  a  project  to  enter  the
development  stage when  it obtains  a conditional  contract on  the land, which
generally  is  subject  to  rezoning  or  special  use  permits.  The  Operating
Partnership  will normally not acquire land until  it is satisfied it can obtain
the  entitlements  required   to  develop  a   self-storage  facility.   Typical
self-storage  facility construction costs range from $22 to $25 per net rentable
square foot. Land costs vary by location, with the Operating Partnership's  past
experience  being $12  to $35  per buildable  square foot.  Soft costs,  such as
capitalized interest,  can  add $4  to  $9 per  net  rentable square  foot.  The
Operating  Partnership's development policy requires a projected 12.5% return at
stabilization, in order for the Operating Partnership to develop a facility. The
Operating Partnership considers a property  at stabilization when it reaches  an
85%  physical occupancy  level, which  generally occurs  over an  18 -  24 month
lease-up period.  The  1996 development  efforts  are  not expected  to  have  a
material impact on earnings.
 
    In   1996,  the  Operating  Partnership   anticipates  funding  its  capital
requirements through a contribution from the Company following the sale of  7.03
million  shares  of common  stock  of the  Company at  $31.30  per share  to the
Company's strategic alliance partner, Security Capital U.S. Realty, pursuant  to
a  Stock Purchase  Agreement entered  into on  March 1,  1996. In  addition, the
Operating Partnership anticipates filing a shelf registration statement relating
to $250  million  of unsecured,  nonconvertible  senior debt  securities,  which
should  enable  the  Operating Partnership  to  access the  public  debt markets
efficiently at opportune times.
 
RESULTS OF OPERATIONS:
 
  YEAR ENDED DECEMBER 31, 1995, AS COMPARED TO PERIOD MARCH 24, 1994 (INCEPTION)
THROUGH DECEMBER 31, 1994:
 
    In 1995, the Operating Partnership  reported growth in revenue, income  from
property  operations,  and net  income,  respectively, of  $42.2  million, $27.3
million, and $18.2 million over the prior period. Compared to pro forma  results
for  1994, the Operating Partnership's revenues  grew $21.0 million, income from
property operations increased $12.2  million and net  income rose $5.9  million.
These
 
                                      F-15
<PAGE>
significant   increases  are  primarily  attributable   to  both  the  Operating
Partnership's  aggressive  acquisition  strategy  and  aggressive  rental   rate
increases.  Facility  acquisitions  during  1995, by  quarter,  were  as follows
(dollar and square footage amounts in thousands):

    These acquisitions added 44,000  units, bringing the  total square feet  and
units  of the 159 facilities owned by  the Operating Partnership at December 31,
1995 to 10,715,000 and  105,000, respectively. For the  year, the 96  facilities
owned  on December 31, 1994, provided  74% of the Operating Partnership's rental
income. These facilities' rental income grew  9.1% over pro forma 1994  results.
Approximately  8% of this growth was provided by rate increases. At December 31,
1995, the physical  and economic  occupancy and rent  per square  foot on  these
facilities  was 88%, 81%,  and $9.24, respectively.  The Operating Partnership's
portfolio as a whole had average occupancy at December 31, 1995, of 88% physical
and 81% economic, with an average rent per square foot of $8.93.
 
    Management income increased $365  thousand over the  prior period, and  $216
thousand  over the 1994 pro  forma results. The pro  forma variance reflects the
addition  of  three  managed  facilities  and  management  during  the  year  of
facilities that were subsequently purchased by the Operating Partnership.
 
    Other  Income,  which  consists primarily  of  sales of  lock  and packaging
products and truck rentals,  increased 4% over the  prior period. This  increase
reflects primarily the growth in the number of facilities owned.
 
    Cost of property operations and maintenance was 27.2% of revenue for 1995 as
compared  to 26.5% for the prior period.  This increase reflects the addition of
Indirect Property Operations Cost to support the level of growth experienced  in
1995 and planned in 1996.
 
    Real  estate taxes were 7.2% of revenue for 1995 as compared to 6.5% for the
prior period and 6.8% for the pro forma results. This growth as a percentage  of
revenue  reflects the impact of reassessments on the properties purchased during
1994 and 1995. The majority of the increase is attributable to reassessments  on
acquisitions   with  the  remainder  attributable  to  increased  tax  rates  or
reassessments on properties  owned for  a full year.  The Operating  Partnership
expects  continued  modest real  estate tax  expense growth  as a  percentage of
revenues in 1996.
 
    Direct Property Operating Cost  was 29.9% of rental  income, both on the  96
properties owned at December 31, 1994 and the portfolio as a whole. The property
level margins remained consistent from 1994 to 1995.
 
    General and Administrative ("G&A") expense declined as a percentage of total
revenue  as compared to the  prior period and was  consistent as compared to the
1994 pro forma  results. 1995 G&A  expense was  $2.6 million, or  3.8% of  total
revenue  as compared to $1.4  million or 5.3% in the  prior period. G&A was $762
thousand for the quarter ended December  31, 1995 and the Operating  Partnership
expects  that the  expense will  decline further as  a percentage  of revenue in
1996, while the gross expense will grow as the Operating Partnership expands its
accounting, management information systems,  and human resource departments,  in
connection with its ongoing growth strategy.

<PAGE>
    The  increase in  depreciation and  amortization to  $8.6 million  from $2.9
million in the prior period and $5.7  million on a pro forma basis reflects  the
Operating  Partnership's acquisition of  $220 million of  facilities in 1995. In
addition, the Operating  Partnership amortized  $903 thousand of  the loan  fees
related to short term borrowings in 1995. As of December 31, 1995, the Operating
Partnership has unamortized loan fees of approximately $230 thousand.
 
    Interest  expense was $3.0 million in 1995, a $1.6 million increase over the
prior period. 1995  interest expense represents  weighted average borrowings  of
$47.2  million under the  Operating Partnership's lines of  credit at a weighted
average interest rate of 6.4%.
 
    Interest income in 1995 was $166  thousand, as compared to $658 thousand  in
1994. 1995 interest income represents earnings on overnight deposits and amounts
outstanding  under the  1995 Employee  Stock Purchase  and Loan  Plan, while the
prior period reflected  the temporary investment  of a portion  of the  proceeds
from the Company's two common stock offerings during the Period.
 
  PERIOD MARCH 24, 1994 (INCEPTION) THROUGH DECEMBER 31, 1994:
 
    The  Operating Partnership reported  rental income of  $24.7 million, income
before minority interest of $12.3 million and net income of $12.1 million during
the Period.  These  results reflect  the  significant portfolio  expansion  that
occurred  during 1994. On March 23, 1994,  17 facilities were contributed by the
Company (the  "Original  Properties")  to the  Operating  Partnership.  Property
acquisitions  by quarter were  as follows (dollar and  square footage amounts in
thousands):

    The rental  revenues  reflect the  weighted  average per  square  foot  rent
increases  ranging  from 4.9%  for some  of the  facilities acquired  during the
second quarter to 6.9% for facilities acquired during the first quarter.
 
    There were no rent increases implemented at three of the facilities acquired
during the quarter ended June  30 nor at any  of the facilities acquired  during
the  quarters  ended September  30 and  December  31. The  Operating Partnership
generally operates an  acquisition facility  for three  to six  months prior  to
implementing  rent increases. At December  31, 1994, the Operating Partnership's
physical and  economic occupancy  and rent  per square  foot were  87%, 81%  and
$8.53, respectively.
 
    Cost  of operations  and maintenance expense  was $6.9 million,  or 26.5% of
revenue. The expense  reflects the direct  cost of operating  the 96  properties
owned  by  the  Operating  Partnership  at  December  31,  1994.  The  ratio  is
approximately 4% higher than  the pro forma ratio  in the Company's  Prospectus,
dated  September 22, 1994. The 4%  increase reflects the Operating Partnership's
level of acquisition during  the fourth quarter  as there tends  to be a  slight
time  lag between the cost structure the  Operating Partnership puts in place at
an acquisition facility and  the related impact  of the Operating  Partnership's
rent increases.
 
    Real  estate tax expense was $1.7 million  or 6.5% of revenue. The Operating
Partnership evaluates real  estate taxes  on a  property by  property basis  and
appeals assessments where it deems the action warranted.
 
                                      F-17
<PAGE>
    General  and  Administrative expense  was $1.4  million in  1994, reflecting
growth in the number of facilities owned.
 
    The 1994 depreciation expense of $2.9 million reflects the expansion in  the
number  of facilities  owned. The facilities  acquired during the  Period had an
average depreciable base of 73% of cost.
 
    Interest expense was $1.4 million. The Operating Partnership had a  weighted
average  of approximately $20.5 million in debt outstanding during the Period at
a weighted average interest rate of 6.8%.
 
    Interest income was $0.7  million reflecting the  temporary investment of  a
portion of the proceeds contributed by the Company from the Company's two common
stock offerings during the Period.
 
  YEAR ENDED DECEMBER 31, 1995, RESULTS OF THE OPERATING PARTNERSHIP AS COMPARED
TO THE COMBINED (HISTORICAL) YEAR ENDED DECEMBER 31, 1994 RESULTS OF THE
PREDECESSOR AND THE OPERATING PARTNERSHIP:
 
    Rental Income increased $39.4 million (146%) primarily as a result of rental
rate increases, and an increase in the number of facilities owned as a result of
the  Operating  Partnership acquiring  63  facilities during  fiscal  year 1995.
Management income increased $.18 million (20%) reflecting the addition of  three
managed  facilities  and  management during  the  year of  facilities  that were
subsequently purchased by the Operating Partnership.
 
    Cost of property operations and  maintenance increased $10.8 million  (142%)
as  a result of an increase in the number of facilities owned during fiscal year
1995. Cost of property operations and maintenance was 27.2% of revenue for  1995
as compared to 26.9% for the combined 1994 period.
 
    Real  estate taxes increased  $3.1 million (166%) as  a result of additional
expenses due to acquisitions  of 63 facilities during  fiscal year 1995 and  the
impact  of property  reassessments. Real estate  taxes were 7.2%  of revenue for
1995 as compared to 6.5% for the combined 1994 period.
 
    General and administrative (G&A)  expense increased $.9  million (51%) as  a
result  of additional expenses  incurred to support  the Operating Partnership's
aggressive growth strategy. G&A expense was 3.8% of revenue for 1995 as compared
to 6.0% for the combined  1994 period. This decline  as a percentage of  revenue
reflects an overall increase in revenue over the prior year.
 
    Depreciation  and amortization expense increased  $5.5 million (175%) due to
the acquisition of $220 million of facilities in 1995, as well as the impact  of
recognizing a full years of depreciation on the facilities acquired in the prior
period.
 
    Interest  expense  increased  $.4  million  reflecting  the  changes  in the
Operating Partnership's debt structure between the periods.
 
  COMBINED (HISTORICAL) YEAR ENDED DECEMBER 31, 1994 RESULTS OF THE PREDECESSOR
AND THE OPERATING PARTNERSHIP, AS COMPARED TO THE YEAR ENDED DECEMBER 31, 1993
RESULTS OF THE PREDECESSOR:
 
    Rental Income increased $17.0 million (170%) primarily as a result of rental
rate increases, and an increase in the number of facilities owned as a result of
the Operating  Partnership  acquiring 79  facilities  during fiscal  year  1994.
Management  income increased $.04 million (4%)  reflecting growth in revenues at
managed properties.
 
    Cost of property operations and maintenance increased $4.5 million (144%) as
a result of the Company operating 96  facilities during 1994, as compared to  17
facilities  in 1993.  Cost of property  operations and maintenance  was 26.9% of
revenue for the combined 1994 period as compared to 28.0% for 1993.

    Real estate taxes increased $1.2 million  (169%) as a result of an  increase
in  the number  of properties  owned during the  combined periods  of 1994. Real
estate taxes were 6.5% of  revenue for the combined  1994 period as compared  to
6.1%  for 1993. General  and administrative (G&A)  expense increased $.9 million
(104%) as a result  of additional expenses incurred  to support the current  and
future growth in the number of facilities and the related increased requirements
for  accounting, management  information systems,  and administrative personnel.
G&A expense was 6.0%  of revenue for  the combined 1994  period, as compared  to
7.4% for 1993.
 
    Depreciation  and amortization expense increased  $1.8 million (138%) as the
Operating Partnership  acquired 79  facilities  for approximately  $214  million
during 1994.
 
    Interest  expense decreased  $1.8 million as  a result  of the Predecessor's
outstanding mortgage debt balance being significantly reduced through the use of
the proceeds from the Company's March 1994 initial public offering.
 
  PRO FORMA RESULTS OF OPERATIONS FOR THE PERIOD JANUARY 1, 1994 THROUGH
DECEMBER 31, 1994:
 
    The Operating  Partnership believes  that pro  forma results  of  operations
provide  a meaningful and relevant  understanding of the Operating Partnership's
results as if it  had been operating  since January 1,  1994. The following  pro
forma  results of  operations were prepared  as if: (i)  the sale in  the IPO of
6.325 million  shares  of  the  Company's  common  stock  for  net  proceeds  of
approximately  $125.8 million, the related transactions and the contributions of
the proceeds to the Operating Partnership, (ii) the sale of 5.980 million shares
of the Company's  common stock  for aggregate proceeds  of approximately  $155.5
million in a secondary offering, the related transactions, and the contributions
of  the proceeds to the Operating Partnership,  and (iii) the acquisition of the
79 facilities acquired during the year, had taken place on January 1, 1994.
 
    The pro forma information  is not necessarily indicative  of the results  of
operations  which may have occurred if such transactions had been consummated on
January 1, 1994, nor does it purport to represent the results of operations  for
future periods.

LIQUIDITY AND CAPITAL RESOURCES:
 
  CAPITAL RESOURCES:
 
    On  March 1, 1996, the Company entered  into a Stock Purchase Agreement with
Security Capital  U.S. Realty  (US  Realty), an  affiliate of  Security  Capital
Group.  Under  the  Stock  Purchase  Agreement and  pursuant  to  the  terms and
conditions thereof,  US  Realty will  invest  a total  of  $220 million  in  the
Company,  initially  place  two  of  its  nominees  on  the  Company's  Board of
Directors, one of whom the Company has been informed will be William D. Sanders,
Chairman of the Board and Chief Executive Officer of Security Capital Group, and
make available to  the Company  certain strategic advice,  research and  related
information   and  expertise  (the   "Strategic  Alliance").  As   part  of  the
transaction, on March 19, 1996, the Company issued to US Realty 1,948,882 shares
of Common Stock, approximately 10.0% of the outstanding Common Stock, at a price
of $31.30 per share, plus a purchase price adjustment for accrued dividends, and
contributed the proceeds  to the Operating  Partnership. At the  same time,  the
Company  executed  a  Strategic  Alliance Agreement  and  a  Registration Rights
Agreement with US Realty.
 
    The Company believes  that the Strategic  Alliance represents an  attractive
opportunity to improve long-term shareholder value by providing the Company with
access to significant additional financial and strategic resources not otherwise
readily  available  to  it,  thereby  enhancing  the  Company's  short-term  and
long-term  growth  prospects  and  better   positioning  it  to  capitalize   on
opportunities as the REIT industry matures.
 
    After  the Strategic Alliance  has been approved by  the shareholders of the
Company, and prior to December 31, 1996, the Company will issue to US Realty  an
additional  5,079,872 shares  of the Company's  common stock at  the same price.
After acquiring  the additional  shares (and  assuming no  other change  in  the
number  of outstanding  shares), US Realty  will own approximately  28.6% of the
outstanding Common Stock. The Company has agreed to submit to the shareholders a
proposal to amend the ownership limitations  of the Company's Charter to  permit
US  Realty to acquire up to 37.5%  of the Company's capital stock. The Strategic
Alliance, the amendment,  and certain  related transactions are  expected to  be
submitted  to shareholders  for approval at  the Company's  1996 annual meeting.
Pursuant to  the terms  of the  Partnership Agreement,  the Company  intends  to
contribute proceeds received from US Realty to the Operating Partnership.
 
    The Operating Partnership expects to finance the acquisition and development
of  self-storage facilities primarily  through the Company's  issuance of equity
securities and the contribution of the proceeds to the Operating Partnership  by
the  Company,  and the  Operating Partnership  issuance  of debt  securities. As
described above under  "Strategic Alliance with  Security Capital U.S.  Realty,"
pursuant  to the  Strategic Alliance  with US  Realty the  Company issued  to US
Realty 1,948,882 shares of common stock for  $61 million on March 19, 1996,  and
expects to issue an additional 5,079,872 shares of common stock for $159 million
on or prior to December 31, 1996.
 
    The  Operating Partnership anticipates filing a shelf registration statement
relating to  $250  million  of unsecured,  nonconvertible  debt  securities.  In
addition,  the Company has  outstanding a shelf  registration statement covering
approximately $75 million of  unallocated equity securities. These  registration
statements should permit the Operating Partnership and the Company to access the
public capital markets efficiently when it deems appropriate.
 
    The  Operating Partnership anticipates  using the proceeds  of the Company's
common stock  issuance  to  U.S.  Realty  for  acquisition  and  development  of
self-storage  facilities. The proceeds  from any debt or  equity offering by the
Operating Partnership or the Company would be used to repay borrowings under the
Operating  Partnership's  lines  of  credit  used  to  finance  acquisitions  or
development  and  for  general  purposes. As  a  general  matter,  the Operating
Partnership anticipates utilizing its  lines of credit as  an interim source  of
funds  to acquire  and develop self-storage  facilities and  repaying the credit
lines with longer-term  debt or  equity when management  determines that  market
conditions are favorable. The
 
                                      F-20
<PAGE>
Operating  Partnership  believes that  the combination  of the  Company's common
stock issuance pursuant to the Strategic Alliance, and debt or equity  issuances
pursuant  to the shelf registration statements,  in addition to borrowings under
its credit facilities and issuances of Operating Partnership Units, as described
below, will  provide  the Operating  Partnership  with necessary  liquidity  and
capital resources to meet the requirements of its operating strategies in 1996.
 
    On  February  8,  1995,  the Operating  Partnership  entered  into  a Credit
Agreement for a $55 million unsecured revolving line of credit (the "Line") with
a financial institution acting as  an agent for a  group of lenders. On  October
31,  1995, the First Amendment  to the Credit Agreement  was entered into by the
Operating Partnership increasing  the aggregate commitment  available under  the
Line  to $75 million.  The Line had  an initial termination  date of February 8,
1996, with the Operating Partnership having an option to extend the term for two
successive one-year periods. The Operating Partnership has exercised that  right
and  has extended  the maturity  on the  Line to  February 1997.  The Line bears
interest at various spreads (75 basis points at March 1, 1996) over LIBOR  based
on  the Operating Partnership's debt service coverage. On December 31, 1995, the
Operating Partnership entered into  a $25 million  unsecured term loan  facility
(the "Facility") with the same agent as on the Line. The Facility has a maturity
date  of December  21, 1996,  and bears interest  at various  spreads (135 basis
points at March 1, 1996) over LIBOR.
 
    In addition to  the $75 million  Line, the Operating  Partnership has a  $30
million unsecured line of credit with a commercial bank with an initial maturity
date  of July 1, 1996. This line of credit was increased from $15 million to $23
million in  November  1995 and  increased  to $30  million  after year  end.  In
connection  with the last increase, the lender released its security interest in
13 self-storage facilities  that previously  had been pledged  by the  Operating
Partnership.  This line of  credit, at the option  of the Operating Partnership,
bears interest at Prime or LIBOR plus 2.25%.
 
    The Operating  Partnership assumed  a $2.4  million mortgage  on a  facility
acquired  during  September  1995. The  mortgage  bears interest  at  8.375% and
matures in 2006.
 
    At December 31, 1995,  the Operating Partnership had  $3.4 million of  fixed
rate  debt maturing in 2001,  $2.3 million of fixed  rate date maturing in 2006,
and  $.9  million  of  floating  rate  debt  maturing  in  1999.  The  Operating
Partnership  does not  believe it has  significant refinancing  or interest rate
risk on its  debt. At  December 31, 1995,  the Operating  Partnership had  $15.4
million available under the $23 million line of credit with a commercial bank.
 
    During  1995,  the  Operating  Partnership  revised  its  debt  policy.  The
Operating Partnership's policy limits indebtedness at time of incurrence to  the
lesser  of 50% of  its total assets  at cost or  the amount that  will sustain a
minimum debt service coverage ratio  of 3:1. In addition, following  shareholder
approval  of  the Strategic  Alliance Agreement  with  US Realty,  the Strategic
Alliance Agreement  with US  Realty  will restrict  the Company,  including  the
Operating  Partnership,  from incurring  total  consolidated indebtedness  in an
amount exceeding 60% of the market value of the total assets (generally  defined
as  the sum of (i) the value of the Company's outstanding common stock at $31.30
per share, (ii) the Company's  consolidated outstanding indebtedness, and  (iii)
net  property acquisitions after March 1,  1996). The Operating Partnership does
not anticipate operating  at a  debt level  that would  cause the  debt-to-total
assets  ratio to exceed 40%  for an extended period  of time, and, consequently,
does not believe that these restrictions will materially restrict its operations
or have  a material  adverse effect  on its  financial condition  or results  of
operations,  though there can  be no assurance that  they will not  do so in the
future.
 
    On June 7,  1995, the Company  issued 4.025 million  shares of common  stock
raising net proceeds of approximately $107.6 million. Following the contribution
of  the proceeds to the  Operating Partnership, the proceeds  were used to repay
$99.9 million of  the Operating  Partnership's indebtedness,  and for  portfolio
acquisitions.
 
                                      F-21
<PAGE>
    During 1995, the Operating Partnership issued approximately 600,000 units of
limited  partnership interest ("Units")  valued at approximately  $18 million in
connection with  the  acquisition  of facilities.  The  Operating  Partnership's
acquisition   of  self-storage  facilities  using  Units  as  consideration  may
partially defer the seller's tax liability.
 
    The Operating Partnership's investing  activities during the year  consisted
primarily  of the acquisition of  63 self storage facilities,  a warehouse to be
converted  by  the  Operating  Partnership  into  a  self-storage  facility,  11
expansion  parcels of  land at  existing facilities and  one parcel  of land for
development by the Operating Partnership.
 
    The Operating Partnership  expects to incur  approximately $1.2 million  for
scheduled   maintenance  and   repairs  during   the  next   twelve  months  and
approximately $5.9 million to conform  facilities acquired during 1995 and  1994
to Operating Partnership standards.
 
    The  Operating Partnership  at December  31, 1995,  had Partners  Capital of
approximately $385 million, a debt-to-equity ratio of 29.6% and a  debt-to-total
assets ratio of 22.4%.
 
  FUNDS FROM OPERATIONS:
 
    The  Operating Partnership believes FFO  should be considered in conjunction
with net  income and  cash flows  to  facilitate a  clear understanding  of  its
operating  results. FFO  is defined as  net income, computed  in accordance with
generally accepted accounting principles ("GAAP"), excluding gains (losses) from
debt restructuring and  sales of property,  plus depreciation and  amortization,
and  after adjustments for  unconsolidated partnerships and  joint ventures. FFO
should not be considered  as an alternative  to net income as  a measure of  the
Operating Partnership's financial performance or as an alternative to cash flows
from operating activities as a measure of liquidity. FFO does not represent cash
generated  from  operating  activities  in  accordance  with  GAAP  and  is  not
necessarily indicative of cash available  to fund cash needs. Effective  January
1,  1996, the National Association of  Real Estate Investment Trusts amended its
definition of FFO. The Operating Partnership will begin presenting FFO under the
amended  definition  for  the  first  quarter  1996.  As  such,  the   Operating
Partnership's  1995 FFO  and FFO  per share may  not be  comparable to similarly
titled measures of other REITs who may have chosen early adoption of the amended
method of FFO computation. The pro forma FFO was prepared as if the IPO and  the
related  formation transactions, including the acquisition of the 26 facilities,
had occurred on January 1, 1994.
 
    The  following   table  illustrates   the   components  of   the   Operating
Partnership's  FFO  for the  year  ended December  31,  1995, the  period ending
December 31,  1994 and  pro  forma for  the year  ended  December 31,  1994  (in
thousands except per share data):

    The  Company, as a  qualified REIT, is required  to distribute a substantial
portion of  its net  income as  dividends to  its shareholders.  In 1995,  those
distributions  were approximately 85% of the Company's funds from operations. It
is the intent of the Operating Partnership that cash distributions will be  made
for each fiscal year to enable the Company to meet its distribution requirements
for  qualification  as a  REIT.  While the  Operating  Partnership's goal  is to
generate  and   retain   sufficient   cash   flow   to   meet   its   operating,
 
                                      F-22
<PAGE>
capital  and debt service  needs, its distribution  requirements may require the
Operating Partnership to utilize its bank  lines of credit and other sources  of
liquidity  to finance property  acquisitions and development,  and major capital
improvements.
 
    The Operating Partnership believes that its liquidity and capital  resources
are adequate to meet its cash requirements for the next twelve months.
 
  FUTURE ACTIVITIES:
 
    The  Company's  strategic  alliance  with  US  Realty  will  not  affect the
Operating Partnership's business  plan or growth  strategies for 1996.  However,
the  alliance  has positively  affected  the Operating  Partnership's  access to
capital. Pursuant to the terms of  the alliance, US Realty will provide  certain
economic  and market research, and assistance in capital strategy and formation.
The Operating Partnership expects that this alliance will positively impact  the
formulation  of the Operating  Partnership's longer term  strategic plan and its
ability to execute its strategies.
 
    The Operating  Partnership's external  growth strategy  is to  increase  the
number  of facilities  owned by  the Operating  Partnership either  by acquiring
suitably  located,  under-performing   facilities  that   offer  potential   for
improvement  of occupancy or rental rates, or by developing and constructing new
facilities  in  favorable   markets.  The  Operating   Partnership,  since   its
commencement, has made approximately $435 million of acquisitions. The Operating
Partnership  expects to  continue investing  at a  consistent pace  during 1996,
seeking to  acquire approximately  65-75 facilities.  The Operating  Partnership
anticipates purchasing properties in 1996 at an average yield on trailing NOI of
not less than 10%.
 
    The Operating Partnership will continue to selectively develop facilities in
markets  that  are  determined  by management  to  be  favorable.  The Operating
Partnership  has  budgeted   commitments  of  approximately   $30  million   for
development  beginning  in  1996.  The development  activities  will  consist of
additions to  existing  facilities  and  construction  of  new  facilities.  The
Operating  Partnership, at  December 31,  1995, had  12 parcels  of land  in its
portfolio in  various  stages  of development.  The  Operating  Partnership  has
entered  into  an  agreement  to develop  a  self-storage  facility  in Northern
Virginia, to be owned jointly by  the Operating Partnership and an  unaffiliated
third  party.  The  Operating  Partnership  estimates  that  its  share  of  the
construction expenses under  the agreement will  be approximately $6.5  million.
The  Operating Partnership expects to complete construction in April of 1996 and
at December 31,  1995, had  incurred costs  of approximately  $3.3 million.  The
Operating  Partnership is converting a warehouse into a self-storage facility at
an estimated  cost of  construction of  $1 million.  At December  31, 1995,  the
Operating  Partnership  had incurred  construction  costs of  approximately $400
thousand, and expects to complete the facility  by the end of the first  quarter
of 1996.
 
    At  December  31,  1995,  the Operating  Partnership  had  1,025,423 Limited
Partnership  Units  outstanding.  Certain   Limited  Partnership  Units   became
redeemable  beginning on March 23, 1995, for  an amount equal to their then fair
market value ($2.7 million, based upon a  price per Unit of $32.625 at  December
31,  1995)  payable by  the  Operating Partnership  either  in cash  or  (at the
Operating Partnership's  option, based  upon a  determination by  the  Company's
Board   of  Directors   that  the   Operating  Partnership's   anticipated  cash
requirements and anticipated cash flow make  a lump sum payment imprudent) by  a
promissory  note payable in quarterly installments  over two years with interest
at the prime rate. Units held by  other Limited Partners are redeemable, at  the
option  of such  Limited Partners, beginning  on the first  anniversary of their
issuance, for amounts equal to the then fair market value of their Units  ($11.3
million, based upon a price per Unit of $32.625 at December 31, 1995) payable by
the   Operating  Partnership  in  cash  or,  at  the  option  of  the  Operating
Partnership, in shares  of the Company's  Common Stock at  the initial  exchange
ratio  of one share for each Unit. As  of March 29, 1996, no Limited Partner has
requested to redeem Units. It is anticipated that a source of funds for any such
cash redemption will be retained cash flow  or proceeds from the future sale  of
securities  of  the  Operating Partnership  or  the Company  or  other Operating
Partnership or Company indebtedness. The Company
 
                                      F-23
<PAGE>
has granted  registration rights  to  the holders  of  Units entitling  them  to
require  the Company to register under the  Securities Act of 1933 any shares of
the Company's common stock issued upon redemption of Units held by them.
 
    Portfolio expansion  and repayment  of  principal on  Operating  Partnership
indebtedness   represent   the   Operating   Partnership's   primary   liquidity
requirements. The Operating Partnership does  not expect to generate  sufficient
funds  from  operating cash  flow  to meet  such  long-term liquidity  needs and
intends to finance them primarily through borrowings under its lines of  credit,
debt or equity offerings, or additional borrowings for such purpose.
 
  COMPETITION:
 
    The   Operating  Partnership   monitors  the   development  of  self-storage
facilities in its markets. The Operating Partnership has identified four markets
in which potential  overbuilding may  be occurring.  In three  of these  markets
(Dallas,  Atlanta, and  Phoenix) the  Operating Partnership  may be  required to
reduce by  50%  its normal  yearly  rental rate  increase,  and in  one  market,
Albuquerque,  the Operating Partnership  may be unable  to aggressively increase
rates in 1996. All of these markets may also demonstrate a minimal reduction  in
the seasonal physical occupancy achieved throughout the year. As a result of the
geographic  diversity of  the Operating  Partnership's portfolio,  the Operating
Partnership does not expect the potential for excess supply in these markets  to
have a significant impact on its financial condition or results of operations.
 
  INFLATION:
 
    The  Operating Partnership does  not believe that inflation  has had or will
have a direct effect on its operations.  Substantially all of the leases at  the
facilities  allow  for  monthly  rent  increases  which  provide  the  Operating
Partnership with the opportunity to achieve  increases in rental income as  each
lease matures.
 
  SEASONALITY:
 
    The Operating Partnership's revenues typically have been higher in the third
and  fourth quarter  primarily because  the Operating  Partnership increases its
rental rates on  most of its  storage units at  the beginning of  May, and to  a
lesser  extent  because  self-storage  facilities  tend  to  experience  greater
occupancy during  the late  spring, summer,  and early  fall months  due to  the
greater  incidence  of moves  during  those periods.  The  Operating Partnership
believes that its tenant  mix, rental structure,  and expense structure  provide
adequate  protection against undue  fluctuations in cash  flows and net revenues
during off-peak  seasons.  Thus,  the  Operating  Partnership  does  not  expect
seasonality to materially affect distributions to unitholders.
 
  RECENT ACCOUNTING DEVELOPMENTS:
 
    In  October of  1995, Statement of  Financial Accounting  Standards No. 123,
"Accounting for Stock-Based Compensation" ("FAS  123") was issued. The  standard
is  effective for fiscal years beginning  after December 15, 1995. The Operating
Partnership anticipates continuing  to elect expense  recognition under APB  25,

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                  (AMOUNTS IN THOUSANDS, EXCEPT PER UNIT DATA)
 
1.  ORGANIZATION:
 
    SUSA  Partnership,  L.P.  (the  "Operating  Partnership"),  which  commenced
operation on March 23, 1994, is engaged in owning, developing, constructing  and
operating  self-storage facilities  throughout the  United States.  Storage USA,
Inc. (the "Predecessor"  See Note 11),  a Tennessee corporation,  was formed  in
1985  to own, develop, construct  and operate self-storage facilities throughout
the United  States. On  March 23,  1994, the  Predecessor completed  an  initial
public  offering (the "IPO") of  6,325,000 shares of common  stock at $21.75 per
share forming Storage USA, Inc. (the "Company"), the sole general partner in the
Operating Partnership. The Company is a self-administered and self-managed  real
estate investment trust ("REIT").
 
    The results for the period prior to January 1, 1994, and for the period from
January  1, 1994, through March  23, 1994 are presented  for the Predecessor and
are labeled as such on the financial statements.
 
    On March 23,  1994, the  Company contributed  substantially all  of its  net
assets of approximately $109,969 to the Operating Partnership in exchange for an
approximately  98.9% general partnership interest  in the Operating Partnership.
The Operating Partnership used the contribution  from the Company to acquire  26
self-storage facilities from unrelated third parties, to acquire the outstanding
partnership interests in five controlled facilities, and for working capital.
 
    In  addition, the Operating Partnership  formed SUSA Management, Inc. ("SUSA
Management"), to provide  self-storage management to  third parties and  certain
ancillary  services. The Operating Partnership owns 99% of the economic interest
of SUSA Management.
 
    On September 29, 1994, the Company contributed approximately $145,514 to the
Operating Partnership in exchange for  approximately 5,980 units of interest  in
the   Operating  Partnership  ("Units").  The  Operating  Partnership  used  the
contribution from  the  Company  to  acquire  27  self-storage  facilities  from
unrelated  third parties, to  retire approximately $33,200  of indebtedness, and
for working capital. On  June 7, 1995, the  Company contributed $108,169 to  the
Operating  Partnership in exchange for  approximately 4,025 Units. The Operating
Partnership used the  contribution from the  Company to acquire  and repay  debt
related to the acquisition of 34 self-storage facilities.
 
    On October 31, 1995, the Company contributed $6,727 of notes receivable from
employees  who  are officers  of  the Company  to  the Operating  Partnership in
exchange for  approximately  230 Units.  During  1995, the  Company  contributed
approximately  $219  of  proceeds  from various  issuances  of  common  stock in
exchange for approximately 8 Units.
 
2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
  BASIS OF PRESENTATION:
 
    The consolidated financial statements include the accounts of the  Operating
Partnership and SUSA Management. All intercompany balances and transactions have
been  eliminated.  The  financial  statements  reflect  the  segregation  of the
operating  activities  for  the  periods  presented  related  to  the  Operating
Partnership  and  the  Predecessor, which  has  been  accounted for  on  a basis
consistent with the Operating Partnership except for the items noted in Note 12.
 
  USE OF ESTIMATES IN PREPARATION OF FINANCIAL STATEMENTS:
 
    The  preparation  of  financial  statements  in  conformity  with  generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions that  affect the  reported  amounts of  assets and  liabilities  and

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
  FEDERAL INCOME TAXES:
 
    No provision has been made for income taxes in the accompanying consolidated
financial statements since  such taxes, if  any, are the  responsibility of  the
individual partners.
 
  CASH AND CASH EQUIVALENTS:
 
    The  Operating  Partnership  considers all  highly  liquid  debt instruments
purchased with maturity of three months or less to be cash equivalents.
 
  REVENUE RECOGNITION:
 
    Rental income and management  income is recorded when  due from tenants  and
customers.  Rental income received  prior to the  start of the  rental period is
included in rents received in advance.
 
  INVESTMENT IN STORAGE FACILITIES:
 
    Storage facilities are recorded at cost. Depreciation is computed using  the
straight  line method over estimated useful lives  of 40 years for buildings and
improvements, and  three to  ten years  for furniture,  fixtures and  equipment.
Expenditures for significant renovations or improvements which extend the useful
life  of assets are  capitalized. Repairs and maintenance  costs are expensed as
incurred.
 
    During 1995,  the  Operating  Partnership adopted  Statement  of  Accounting
Standards No. 121 "Accounting for Impairment of Long-Lived Assets." The adoption
of  this  standard  had  no  impact  on  the  Operating  Partnership's financial
statements. Impairment is evaluated based upon comparing the sum of the expected
future cash flows (undiscounted  and without interest  charges) to the  carrying
value  of the asset. If the cash flows is less, an impairment loss is recognized
for the amount by which the carrying amount of the assets exceeds the fair value
of the asset.
 
  OTHER INCOME:
 
    Other income  consists primarily  of  sales of  storage-related  merchandise
(locks and packing supplies) and commissions from truck rentals.
 
  MINORITY INTEREST:
 
    The  minority  interest  reflects  the  ownership  interest  of  the limited
partners in two  facilities in which  the Operating Partnership  is the  general
partner.  The  limited  partner's  share  of the  net  income  of  the Operating
Partnership is charged to minority interest expense and increases the  Operating
Partnership's  liability.  Distributions  to the  limited  partners  reduces the
Operating Partnership's liability.
 
  OTHER ASSETS:
 
    Included in other assets in 1995 and 1994, respectively, are $4,842 and $327
of costs related to two development  projects, $257 and $63 due from  affiliate,
prepaid  expenses,  accounts receivable  and  intangible assets.  The intangible
assets at December 31,  1995 and 1994, respectively,  consist primarily of  loan
acquisition   costs  of  approximately   $254  and  $230,   net  of  accumulated
amortization of approximately $24  and $78, a covenant  not to compete of  $500,
net  of accumulated  amortization of  approximately $415  and $167,  and minimum
lease  guarantees  of  approximately  $189  and  $186,  which  have  been  fully
amortized.  Loan acquisition costs  are amortized over the  terms of the related
debt, the  covenant is  amortized over  the contract  period of  the  agreement.
Amounts  under minimum lease  guarantees on five  of the Operating Partnership's
facilities are amortized as earned.
 
  INCOME PER UNIT:
 
    Net income per unit is calculated using the weighted average number of Units
outstanding during the period.

5.  LINE OF CREDIT BORROWINGS:
 
    Line  of credit  borrowings at  December 31,  1995, consists  of $100,000 of
borrowings under a $100,000 line of credit with a group of commercial banks, and
$7,605 of borrowings under a $23,000 line of credit with a commercial bank.  The
balance at December 31, 1994, consists of $4,000 of borrowings under the $23,000
line.  The  $100,000 facility,  consists of  a $75,000  tranche with  an initial
termination date of  February 8,  1996, and a  $25,000 tranche  with an  initial
termination  date  of April  21,  1996. On  the  $75,000 tranche,  the Operating
Partnership has  an  option to  extend  the term  for  two successive  one  year
periods.  On the  $25,000 tranche,  the Operating  Partnership has  an option to
extend the term until December 21,  1996. Subsequent to year end, the  Operating
Partnership  exercised  its  option  on the  $75,000  tranche  and  extended the
maturity to February 8, 1997. This line bears interest at various spreads over a
base rate  based  on the  Operating  Partnership's debt  service  coverage.  The
weighted  average borrowings during the year  was $41,662, the maximum borrowing
outstanding under the  line during  the period  was $100,000,  and the  weighted
average  interest rate during the year was 6.1%. The $23,000 line consists of an
$8,000 tranche maturing on February 15, 1996, and a $15,000 tranche maturing  on
July  1, 1996. Both tranches,  at the option of  the Operating Partnership, bear
interest at prime or LIBOR plus 2.25%, and are collateralized by mortgages on 13
facilities. The facilities have a net book value of $28,035. Subsequent to  year
end,  the commercial bank agreed to release  the mortgages, increase the line to
$30,000 with an  initial maturity of  July 1, 1996,  and continue the  borrowing
arrangement.  During  1995 and  1994, respectively,  the weighted  average daily
borrowings were $5,513 and $4,900, the maximum borrowings outstanding under  the
line were $21,700 and $11,500, and the weighted average interest rates were 8.9%
and 6.5%.

employee's behalf equal to 50% of the participant's contribution to the plan, up
to 2% of  the participant's compensation.  Operating Partnership profit  sharing
contributions  to the plan are determined annually by the Operating Partnership.
Operating Partnership contributions totaled $223 and $137 during 1995 and  1994,
respectively.
 
10. PARTNERSHIP CAPITAL:
 
    The  Company, as  a corporate  general partner,  has Stock  Option, Employee

  EMPLOYEE STOCK PURCHASE AND LOAN PLAN (AMOUNTS NOT IN THOUSANDS):
 
    In 1995, the  Company issued 230,000  shares of its  common stock under  the
1995  Employee Stock Purchase and Loan Plan.  Pursuant to the terms of the plan,
the Company and certain officers entered into stock purchase agreements  whereby
the  officers  purchased common  stock  at the  then  current market  price. The
Company provides 100% financing for the purchase of the shares with interest  at
7%  per annum payable quarterly. The underlying  notes are secured by the shares
and mature in November 2002. Under  the terms of the partnership agreement,  all
proceeds from the issuance of common stock under the plan are contributed to the
Operating Partnership in exchange for Operating Partnership Units.
 
  DIVIDEND REINVESTMENT AND STOCK PURCHASE PLAN:
 
    In  1995, the Company  adopted the Dividend  Reinvestment and Stock Purchase
Plan (the "Plan").  Under the  Plan, the Company  offers holders  of its  common
stock  the  opportunity to  purchase, through  reinvestment  of dividends  or by
additional cash payments, additional shares of  its common stock. The shares  of
common  stock for participants may be purchased  from the Company at the greater
of the average high and  low sales price or the  average closing sales price  on
the  investment date or in the  open market at 100% of  the average price of all
shares purchased for  the Plan. During  1995, 653 shares  were issued under  the
Plan.  Under  the terms  of  the partnership  agreement,  all proceeds  from the
issuance of  common  stock under  the  plan  are contributed  to  the  Operating
Partnership in exchange for Operating Partnership units.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
                  (AMOUNTS IN THOUSANDS, EXCEPT PER UNIT DATA)
 
11. SUMMARY OF PREDECESSOR SIGNIFICANT ACCOUNTING POLICIES:
 
  BASIS OF PRESENTATION:
 
    The  accompanying  combined financial  statements for  the periods  prior to
March 24,  1994  present  only  the "carved-out"  accounts  of  the  Predecessor
comprised   of  the  continuing  assets,   liabilities  and  operations  of  the
Predecessor following the IPO, including 11 owned facilities and six  controlled
facilities   (Original  Facilities)  and   Storage  USA  Management  Corporation
(Management Corp.). All other  accounts of the  Predecessor were excluded  since
the  business segments  to which  they relate  were discontinued  by the Company
before the  IPO.  Due  to  common  ownership  and  management  of  the  Original
Facilities  and Management Corp., the  historical financial statements have been
accounted for as a group of entities  under common control, which is similar  to
the   accounting  method  used  for  a  pooling  of  interest.  All  significant
intercompany transactions  and balances  have been  eliminated in  the  combined
presentation.  The  financial information  included  herein may  not necessarily
reflect the financial position and results of operations of the Predecessor  had
it  been a  separate stand-alone  entity during the  periods prior  to March 24,
1994.
 
  MINORITY INTEREST:
 
    The Predecessor financial statements include the accounts of six  facilities
(Selling  Partnerships) which were owned by investment partnerships in which the
Predecessor or its affiliates had a controlling interest. The ownership interest
of the other partners  in these partnerships is  treated as a minority  interest
and  reported as a liability of  the Predecessor. Increases in minority interest
are charged to operations.
 
  FEDERAL INCOME TAXES:
 
    The Predecessor was an S Corporation and thus was not subject to taxation at
the corporate level.  The self-storage facilities  owned through the  investment
partnerships  required the partners to include their respective share of profits
and losses  in  their  individual  tax returns.  Therefore,  the  statements  of
operations  contain no provision for federal  income taxes for any periods prior
to March 24, 1994.
 
  SHAREHOLDERS' DEFICIT:
 
    The Predecessor's  President  and  Chief  Executive  Officer  contributed  a
portion  of his interests in two of the Selling Partnerships in exchange for the
satisfaction of his indebtedness to the Predecessor. The value attributed to his
interest in the  Selling Partnerships was  determined on the  same basis as  the
determination  of  payments made  by the  Predecessor  to the  unrelated limited
partners in the Selling Partnerships.
 
    Corporate reorganization adjustments consist  primarily of dividends  deemed
cash  distributions, reclassification  of certain minority  interests, and other
non-cash adjustments relating to the IPO.
 
  RELATED PARTY TRANSACTIONS:
 
    The Predecessor  had  demand notes  payable  to the  Predecessor's  founder,
bearing  interest at prime plus  2% (8% at December  31, 1993). These notes were
collateralized by second mortgages on certain of the Original Facilities.  Total
interest  expense to  affiliates amounted to  approximately $178  and $1,426 for
period from January 1, 1994  to March 23, 1994 and  the year ended December  31,
1993, respectively.
 
  OTHER:
 
    There  was no significant Investment in  Storage Facilities activity for the
period from January 1, 1994  to March 23, 1994 and  for the year ended  December
31, 1993.

11. SUMMARY OF PREDECESSOR SIGNIFICANT ACCOUNTING POLICIES: (CONTINUED)
    Total  cash paid for  interest expense related to  the mortgages payable and
notes payable balances for the period from January 1, 1994 to March 23, 1994 and
the year ended December 31, 1993 was $1,017 and $3,006, respectively.
 
12. SUBSEQUENT EVENTS:
 
  FORMATION OF STRATEGIC ALLIANCE:
 
    On March 1, 1996, the Company  entered into a Stock Purchase Agreement  with
Security  Capital  U.S. Realty  (US Realty),  an  affiliate of  Security Capital
Group. Under the Stock Purchase Agreement,  subject to the terms and  conditions
thereof,  US Realty will  invest a total  of $220,000 in  the Company, initially
place two of its nominees on the  Company's Board of Directors, one of whom  the
Company  has been informed will be William D. Sanders, Chairman of the Board and
Chief Executive Officer  of Security Capital  Group, and make  available to  the
Company certain strategic advice, research and related information and expertise
(the  "Strategic Alliance"). As part of the  transaction, on March 19, 1996, the
Company issued  to US  Realty 1,948,882  shares of  Common Stock,  approximately
10.0%  of the outstanding Common  Stock, at a price of  $31.30 per share, plus a
purchase price adjustment for accrued dividends.  At the same time, the  Company
executed a Strategic Alliance Agreement and a Registration Rights Agreement with
US Realty.
 
    After  the Strategic Alliance  has been approved by  the shareholders of the
Company, and prior to December 31, 1996, the Company will issue to US Realty  an
additional  5,079,872 shares of the Company's common stock at the same price for
an aggregate of $159,000. After acquiring the additional shares (and assuming no
other  change  in  the  number  of  outstanding  shares),  US  Realty  will  own
approximately  28.6%  of  the outstanding  Common  Stock. The  proceeds  of both
fundings will  be  contributed to  the  Operating Partnership  in  exchange  for
additional  Operating Partnership Units and used  to support the acquisition and
development of self-storage facilities.
 
    The Company has agreed to submit to the shareholders a proposal to amend the
ownership limitations of the Company's Charter to permit US Realty to acquire up
to 37.5% of the Company's capital stock. The Strategic Alliance, the  amendment,
and  certain related transactions  are expected to  be submitted to shareholders
for approval at the Company's 1996 annual meeting.
 
  PROPERTY ACQUISITIONS:
 
    Subsequent to December 31, 1995, the Operating Partnership has completed the
acquisition  of  six  self-storage  facilities  for  approximately  $21,460.  In
addition, the Operating Partnership purchased two land parcels for approximately
$688.  These  acquisitions  were  financed  through  operating  cash  flows  and
borrowings under the $30,000 line of credit.
 
  INTEREST RATE SWAP AGREEMENT:
 
    In anticipation  of  a debt  offering  in 1996,  the  Operating  Partnership
entered into an interest rate swap agreement in October 1995, with the objective
of  reducing its  exposure to future  interest rate  fluctuations. The agreement
involved the  exchange of  a variable  rate for  a fixed  rate interest  payment
obligation.  The  agreement  had a  notional  principal amount  of  $100,000, an
effective date of March 1, 1996, and a maturity date of March 1, 2003. On  March
8,  1996, the Operating Partnership closed  the interest rate swap agreement and
received proceeds of  approximately $50. The  Operating Partnership  anticipates
filing  a  $250,000  debt shelf  registration  statement  on Form  S-3  with the
Securities and Exchange Commission. Upon successful completion of an offering of
unsecured debt  securities  under  the shelf,  the  Operating  Partnership  will
recognize the gain as a yield adjustment over the life of the debt.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors
 
 and Shareholders of Storage USA, Inc.
 
    We  have  audited  the  accompanying  consolidated  balance  sheets  of SUSA
Partnership, L.P.  (the "Operating  Partnership") as  of December  31, 1995  and
1994,  and  the  related consolidated  statements  of  operations, shareholders'
equity, and cash flows for the year ended December 31, 1995, and for the  period
from March 24, 1994, (inception) through December 31, 1994. We have also audited
the  accompanying combined  statements of operations,  shareholders' equity, and
cash flows of Storage USA, Inc. (the "Predecessor") for the period from  January
1,  1994 through March  23, 1994 and for  the year ended  December 31, 1993 (See
Note 1  and  11). These  financial  statements  are the  responsibility  of  the
management  of the  Operating Partnership. Our  responsibility is  to express an
opinion on these financial statements based on our audits.
 
    We conducted  our  audits in  accordance  with generally  accepted  auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence  supporting
the  amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used  and the significant estimates made  by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
    In our opinion, the financial  statements referred to above present  fairly,
in  all material respects, the consolidated  financial position of the Operating
Partnership as  of December  31, 1995  and 1994,  the consolidated  results  its
operations  and its cash flows for the year  ended December 31, 1995 and for the
period from  March  24, 1994  (inception)  through  December 31,  1994  and  the
combined  results of the Predecessor's operations  and cash flows for the period
from January 1, 1994 through March 23, 1994 and for the year ended December  31,
1993, in conformity with generally accepted accounting principles.
